控制上行链路功率Control Uplink Power

技术领域technical field

本公开涉及在载波聚合被应用的情况下在用户设备中复用上行链路信道和在上行链路上传输的上行链路参考信号，并且控制上行链路功率。The present disclosure relates to multiplexing an uplink channel and an uplink reference signal transmitted on an uplink in a user equipment and controlling uplink power in a case where carrier aggregation is applied.

背景技术Background technique

载波聚合(CA)为信号通过两个或者更多个分量载波的传输和接收。在载波聚合中，用户设备可以向传输/接收点同时传输上行链路信道(例如上行链路数据信道和/或上行链路控制信道)和上行链路信号。在这种情况下，典型地，用户设备的单个传输时间提前量(TA)值被同一地施加于所有不同分量载波或者所有不同服务小区。这里，传输TA值由传输/接收点来指出。Carrier aggregation (CA) is the transmission and reception of signals over two or more component carriers. In carrier aggregation, a user equipment can simultaneously transmit uplink channels (eg, uplink data channels and/or uplink control channels) and uplink signals to a transmission/reception point. In this case, typically a single transmission timing advance (TA) value for a user equipment is applied identically to all different component carriers or to all different serving cells. Here, the transmission TA value is indicated by the transmission/reception point.

然而，在为用户设备指出的多个传输TA值的情况下，可能需要上行链路信道与不同分量载波(或者服务小区)或者分量载波组(或者服务小区组)上的上行链路信号之间的复用和/或功率控制方法与单个TA情况下的复用和/或功率控制方法不同。However, in case of multiple transmission TA values indicated for the user equipment, there may be a need for communication between uplink channels and uplink signals on different component carriers (or serving cells) or groups of component carriers (or groups of serving cells). The multiplexing and/or power control method in the case of a single TA is different from the multiplexing and/or power control method in the case of a single TA.

A wireless communication system 100 such as a CoMP system may include a plurality of transmission/reception points 110 and 112 and at least one user equipment (UE) 120 and 122 .

与传输/接收点(例如，110和112)中的一个对应的第一传输/接收点(例如，eNB 110)可以执行到用户设备120和122的下行链路传输。第一传输/接收点(例如，eNB 110)可以传输与初级物理信道对应的PDSCH，以用于单播传输。而且，第一传输/接收点(例如，eNB 110)可以传输PDCCH，以便于传输下行链路控制信息(例如，用于接收PDSCH所需要的调度信息)并且传输用于上行链路数据信道(例如PUSCH)传输的调度授权信息。在下文中，“通过信道传输或者接收信号”可以称为“传输或者接收信道”的表达。A first transmission/reception point (eg, eNB 110) corresponding to one of the transmission/reception points (eg, 110 and 112) may perform downlink transmission to user equipments 120 and 122. A first transmission/reception point (eg, eNB 110) may transmit a PDSCH corresponding to a primary physical channel for unicast transmission. Also, the first transmission/reception point (e.g., eNB 110) may transmit PDCCH in order to transmit downlink control information (e.g., scheduling information required for receiving PDSCH) and transmission for uplink data channel (e.g., PUSCH) transmission scheduling grant information. Hereinafter, "transmitting or receiving a signal through a channel" may be referred to as an expression of "transmitting or receiving a channel".

如图1所述，第一用户设备(UE1)120可以向第一传输/接收点(例如eNB110)传输上行链路信号。第二用户设备(UE2)122可以向多个传输/接收点(例如110和112)中的第二传输/接收点(例如RRH 112)传输上行链路信号。可替换地，第一用户设备(UE1)可以向第二传输/接收点(例如RRH 112)传输上行链路信号，并且第二用户设备122可以向第一传输/接收点(例如eNB 110)传输上行链路信号。与图1不同，两个或者更多个用户设备可以被包括在无线通信系统100中。然而，为了描述方便，无线通信系统100将被描述为包括两个用户设备120和122，一个向第一传输/接收点(例如eNB 110)传输上行链路信号，并且另一个向第二传输/接收点(例如RRH 112)传输上行链路信号。As shown in FIG. 1 , a first user equipment (UE1) 120 may transmit an uplink signal to a first transmission/reception point (eg, eNB110). A second user equipment (UE2) 122 may transmit an uplink signal to a second transmission/reception point (eg, RRH 112) of the plurality of transmission/reception points (eg, 110 and 112). Alternatively, the first user equipment (UE1) may transmit an uplink signal to a second transmission/reception point (e.g. RRH 112), and the second user equipment 122 may transmit an uplink signal to the first transmission/reception point (e.g. eNB 110) uplink signal. Unlike FIG. 1 , two or more user equipments may be included in the wireless communication system 100 . However, for convenience of description, the wireless communication system 100 will be described as including two user equipments 120 and 122, one transmitting uplink signals to a first transmission/reception point (e.g. eNB 110), and the other transmitting/receiving a signal to a second transmission/reception point. A receiving point (eg, RRH 112) transmits uplink signals.

在这种情况下，如稍后所述，第一用户设备(UE1)120可以向第一传输/接收点(例如eNB 110)传输上行链路信号，并且第二用户设备(UE2)122可以向第二传输/接收点(例如RRH 112)传输上行链路信号。In this case, as described later, the first user equipment (UE1) 120 may transmit an uplink signal to a first transmission/reception point (e.g. eNB 110), and the second user equipment (UE2) 122 may transmit an uplink signal to A second transmission/reception point (eg, RRH 112) transmits uplink signals.

在无线通信系统中，当执行上行链路传输时，用户设备可以每个时隙传输上行链路解调参考信号(UL DMRS或者UL DM-RS)，使得识别用于解调数据信道的信道信息。在与PUSCH相关联的上行链路DM-RS的情况下，用户设备可以通过每时隙一个符号来传输参考信号。在与PUCCH相关联的上行链路DM-RS的情况下，用户设备可以按照PUCCH格式通过不同数量的符号来传输参考信号。例如，在PUCCH格式1/1a/1b(即PUCCH格式1，PUCCH格式1a以及PUCCH格式1b)的情况下，可以通过每时隙三个符号来传输参考信号。在PUCCH格式2/2a/2b/3(即PUCCH格式2，PUCCH格式2a以及PUCCH格式2b以及PUCCH格式3)的情况下，可以通过每时隙两个符号来传输参考信号。In a wireless communication system, when performing uplink transmission, a user equipment may transmit an uplink demodulation reference signal (UL DMRS or UL DM-RS) every slot so that channel information for demodulating a data channel is identified . In case of an uplink DM-RS associated with PUSCH, a user equipment can transmit a reference signal by one symbol per slot. In case of an uplink DM-RS associated with PUCCH, a user equipment may transmit a reference signal through a different number of symbols in a PUCCH format. For example, in the case of PUCCH format 1/1a/1b (ie PUCCH format 1, PUCCH format 1a and PUCCH format 1b), the reference signal can be transmitted by three symbols per slot. In the case of PUCCH formats 2/2a/2b/3 (ie PUCCH format 2, PUCCH format 2a and PUCCH format 2b and PUCCH format 3), reference signals may be transmitted by two symbols per slot.

PUCCH用作上行链路控制信道且与根据从用户设备传输的信息类型而分类的格式相关联。下面的表1示出PUCCH格式。The PUCCH is used as an uplink control channel and is associated with formats classified according to the type of information transmitted from the user equipment. Table 1 below shows PUCCH formats.

PUCCH格式1/1a/1b(即PUCCH格式1，PUCCH格式1a以及PUCCH格式1b)可以用于传输调度请求(SR)和HARQ-ACK。PUCCH格式2/2a/2b(即PUCCH格式2，PUCCH格式2a以及PUCCH格式2b)可以用于传输信道质量指示(CQI)、预编码矩阵指示(PMI)以及秩指示(RI)。PUCCH格式3可以用于传输多个HARQ ACK/NACK。PUCCH format 1/1a/1b (ie PUCCH format 1, PUCCH format 1a and PUCCH format 1b) can be used to transmit scheduling request (SR) and HARQ-ACK. PUCCH format 2/2a/2b (ie PUCCH format 2, PUCCH format 2a and PUCCH format 2b) can be used to transmit channel quality indicator (CQI), precoding matrix indicator (PMI) and rank indicator (RI). PUCCH format 3 can be used to transmit multiple HARQ ACK/NACK.

在下文中，将更详细地描述每个PUCCH格式及其使用。Hereinafter, each PUCCH format and its use will be described in more detail.

PUCCH格式1为用于仅传输调度请求(SR)的信道格式。PUCCH格式1a/1b(即PUCCH格式1a和PUCCH格式1b)为用于传输调度请求(SR)和/或ACK/NACK的信道格式以用于下行链路数据信道。在本文中，PUCCH格式1a/1b可以根据ACK/NACK的位的数量和对应调制方案来分类。同时，在与ACK/NACK传输相关联的PUCCH格式1a/1b的情况下，可以打孔(puncture)子帧的最后SC-FDMA符号。在这种情况下，使用打孔的SC-FDMA符号的PUCCH格式1a可以称为“缩短的PUCCH格式1a”。同理，使用打孔的SC-FDMA符号的PUCCH格式1b可以称为“缩短的PUCCH格式1b”。可以基于由传输/接收点的相关联的高层提供的RRC参数(例如“ackNackSRS-Simultaneous Transmission”)的值(例如“真”或者“假”)和探测参考符号(SRS)的小区特定信息来选择且使用PUCCH格式1/1a/1b中的一个。PUCCH format 1 is a channel format for transmitting only scheduling requests (SRs). PUCCH format 1a/1b (ie, PUCCH format 1a and PUCCH format 1b) is a channel format for transmitting a scheduling request (SR) and/or ACK/NACK for a downlink data channel. Herein, PUCCH formats 1a/1b can be classified according to the number of bits of ACK/NACK and corresponding modulation schemes. Meanwhile, in case of PUCCH format 1a/1b associated with ACK/NACK transmission, the last SC-FDMA symbol of a subframe may be punctured. In this case, the PUCCH format 1a using punctured SC-FDMA symbols may be referred to as 'shortened PUCCH format 1a'. Similarly, the PUCCH format 1b using punctured SC-FDMA symbols may be called "shortened PUCCH format 1b". Can be selected based on the value (e.g. "true" or "false") of the RRC parameter (e.g. "ackNackSRS-Simultaneous Transmission") provided by the associated higher layer of the transmission/reception point and the cell-specific information of the Sounding Reference Symbol (SRS) And use one of PUCCH formats 1/1a/1b.

PUCCH格式2为用于仅传输信道质量指示(CQI)的信道格式。同时，PUCCH格式2a/2b(即PUCCH格式2a和PUCCH格式2b)为用于传输“CQI”和“与对下行链路数据信道的响应对应的ACK/NACK”的信道格式。PUCCH格式2a/2b可以根据ACK/NACK的位的数量和调制方案来分类。PUCCH format 2 is a channel format for transmitting only channel quality indication (CQI). Meanwhile, PUCCH format 2a/2b (ie, PUCCH format 2a and PUCCH format 2b) is a channel format for transmitting "CQI" and "ACK/NACK corresponding to a response to a downlink data channel". PUCCH formats 2a/2b can be classified according to the number of bits of ACK/NACK and a modulation scheme.

PUCCH格式3为用于传输具有超过四位下行链路载波聚合的长度的ACK/NACK的信道格式。在与ACK/NACK传输相关联的PUCCH格式3的情况下，可以打孔子帧的最后SC-FDMA符号。在这种情况下，使用打孔的SC-FDMA符号的PUCCH格式3可以称为“缩短的PUCCH格式3”。换言之，缩短的PUCCH格式3的最后SC-FDMA符号未被映射到资源单元。可能基于由传输/接收点的相关联的高层提供的RRC参数(例如“ackNackSRS-Simultaneous Transmission”)的值(例如“真”或者“假”)和SRS的小区特定信息来选择且使用PUCCH格式3和缩短的PUCCH格式3中的一个。PUCCH format 3 is a channel format for transmitting ACK/NACK having a length exceeding four-bit downlink carrier aggregation. In case of PUCCH format 3 associated with ACK/NACK transmission, the last SC-FDMA symbol of a subframe may be punctured. In this case, PUCCH format 3 using punctured SC-FDMA symbols may be called 'shortened PUCCH format 3'. In other words, the last SC-FDMA symbol of shortened PUCCH format 3 is not mapped to resource elements. Possibly select and use PUCCH format 3 based on the value (e.g. "true" or "false") of the RRC parameter (e.g. "ackNackSRS-Simultaneous Transmission") provided by the associated higher layer of the transmission/reception point and the cell-specific information of the SRS and one of the shortened PUCCH format 3.

同时，在与无线通信系统对应的LTE通信系统中，解调参考信号(DMRS或者DM-RS)和SRS可以被定义以用于上行链路。三种类型的参考信号(RS)可以被定义以用于下行链路。在本文中，三种类型的参考信号(RS)可以包括小区特定参考信号(CRS)、多播/广播上的单频网络参考信号(MBSFN-RS)以及UE特定参考信号。Meanwhile, in an LTE communication system corresponding to a wireless communication system, a demodulation reference signal (DMRS or DM-RS) and an SRS may be defined for uplink. Three types of Reference Signals (RS) can be defined for downlink. Herein, three types of reference signals (RS) may include a cell-specific reference signal (CRS), a single frequency network reference signal over multicast/broadcast (MBSFN-RS), and a UE-specific reference signal.

上行链路探测参考信号(SRS)可以用于测量上行链路信道状态以用于上行链路频变调度。这种上行链路SRS也可以用于测量上行链路信道状态和下行链路信道状态，以用于在时分双工(TDD)系统中使用信道相互性来下行链路波束形成。在上行链路SRS的情况下，无线通信系统100中的特定传输/接收点或者特定小区可以向用户设备传输用于SRS生产的参数(即用于生成由用户设备传输的SRS的参数)。在本文中，用于SRS生成的参数可以包括小区特定SRS带宽、传输梳、UE特定SRS带宽、与跳跃相关的配置参数、频域位置、周期、子帧配置(指定哪个子帧将传输SRS)、天线配置(指定传输SRS的天线的数量和天线端口的数量)、基序列索引、循环移位索引(即用于SRS生成的参考信号)等。在本文中，传输梳可以指定每隔两种类型的子载波间隔分配的频率位置。例如，“0”可以表示偶数子载波，并且“1”可以表示奇数子载波。基序列索引可以为用于生成对应的SRS的SRS序列索引。可以基于用在PUCCH中的序列组号和根据序列跳跃配置定义的基序列号来确定SRS序列索引。更具体而言，对应的传输/接收点(例如eNB 110)可以向用户设备120传输用于SRS生成的参数作为RRC参数。用户设备120可以从eNB 110接收用于SRS生成的参数，并且向eNB 110传输上行链路SRS。Uplink Sounding Reference Signals (SRS) may be used to measure uplink channel status for uplink frequency-varying scheduling. This uplink SRS can also be used to measure uplink channel status and downlink channel status for downlink beamforming using channel reciprocity in Time Division Duplex (TDD) systems. In case of uplink SRS, a specific transmission/reception point or a specific cell in the wireless communication system 100 may transmit parameters for SRS generation (ie, parameters for generating SRS transmitted by the user equipment) to the user equipment. In this paper, parameters for SRS generation may include cell-specific SRS bandwidth, transmission comb, UE-specific SRS bandwidth, configuration parameters related to hopping, frequency domain location, period, subframe configuration (specify which subframe will transmit SRS) , antenna configuration (specify the number of antennas for transmitting SRS and the number of antenna ports), base sequence index, cyclic shift index (that is, reference signal used for SRS generation), etc. In this paper, the transmission comb can specify frequency positions allocated every two types of subcarrier spacing. For example, "0" may represent even subcarriers, and "1" may represent odd subcarriers. The base sequence index may be an SRS sequence index used to generate a corresponding SRS. The SRS sequence index may be determined based on the sequence group number used in the PUCCH and the base sequence number defined according to the sequence hopping configuration. More specifically, the corresponding transmission/reception point (e.g., eNB 110) may transmit parameters for SRS generation to user equipment 120 as RRC parameters. User equipment 120 may receive parameters for SRS generation from eNB 110 and transmit uplink SRS to eNB 110.

而且，非周期SRS可以连同周期SRS一起被定义。在非周期SRS的情况下，像周期SRS的情况，特定传输/接收点可以向用户设备传输用于生成非周期SRS的参数作为RRC参数。在本文中，用于生成非周期SRS的参数可以包括非周期SRS的UE特定SRS带宽、传输梳、频域位置、周期、子帧配置、天线配置、基序列索引、循环移位索引等，如无线通信系统100中定义的。Also, an aperiodic SRS can be defined together with a periodic SRS. In the case of the aperiodic SRS, like the case of the periodic SRS, a specific transmission/reception point may transmit parameters for generating the aperiodic SRS to the user equipment as RRC parameters. In this paper, the parameters used to generate aperiodic SRS may include UE-specific SRS bandwidth, transmission comb, frequency domain position, period, subframe configuration, antenna configuration, base sequence index, cyclic shift index, etc. of aperiodic SRS, such as defined in the wireless communication system 100.

此外，特定传输/接收点可以通过PDCCH动态触发用户设备120，使得用户设备120可以传输周期SRS。当通过PDCCH和RRC参数接收触发信号时，用户设备120可以传输上行链路非周期SRS。In addition, a specific transmission/reception point can dynamically trigger the user equipment 120 through the PDCCH, so that the user equipment 120 can transmit a periodic SRS. When receiving a trigger signal through the PDCCH and RRC parameters, the user equipment 120 may transmit an uplink aperiodic SRS.

在下文中，在上行链路PUCCH和探测参考信号(SRS)的同时传输被认为在一个子帧的情况下，将详细描述对应的用户设备的操作。Hereinafter, in a case where simultaneous transmission of an uplink PUCCH and a sounding reference signal (SRS) is considered to be in one subframe, the operation of the corresponding user equipment will be described in detail.

在认为同时传输PUCCH和SRS的情况下，对应的用户设备的操作可以按照PUCCH格式类型和SRS类型来定义(或者配置)。在本文中，SRS可以分类成周期SRS(或者在本文中称为“类型0触发的SRS”)和非周期SRS(或者在本文中称为“类型1触发的SRS”)。而且，可以在考虑到适应多个分量载波而定义用户设备的这种操作。In the case that the PUCCH and the SRS are considered to be transmitted at the same time, the operation of the corresponding user equipment can be defined (or configured) according to the PUCCH format type and the SRS type. Herein, SRS may be classified into periodic SRS (or referred to herein as "Type 0 triggered SRS") and aperiodic SRS (or referred to herein as "Type 1 triggered SRS"). Also, such operation of the user equipment can be defined in consideration of adapting to multiple component carriers.

用户设备根据SRS类型(例如周期SRS或者非周期SRS)和PUCCH格式的操作可以被定义如下。The operation of the user equipment according to the SRS type (eg periodic SRS or aperiodic SRS) and PUCCH format can be defined as follows.

(i)在PUCCH格式2/2a/2b传输和周期SRS传输在相同子帧中同时发生的情况下，用户设备可以不传输周期SRS。(i) In the case that PUCCH format 2/2a/2b transmission and periodic SRS transmission occur simultaneously in the same subframe, the user equipment may not transmit periodic SRS.

(ii)在携带ACK/NACK的PUCCH格式2/2a/2b传输和非周期SRS传输在相同子帧中同时发生的情况下，用户设备可以不传输非周期SRS。(ii) In the case that PUCCH format 2/2a/2b transmission carrying ACK/NACK and aperiodic SRS transmission occur simultaneously in the same subframe, the user equipment may not transmit aperiodic SRS.

(iii)在未携带ACK/NACK的PUCCH格式2传输和非周期SRS传输在相同子帧中同时发生的情况下，用户设备可以不传输不具有ACK/NACK的PUCCH格式2。(iii) In case that PUCCH format 2 transmission without ACK/NACK and aperiodic SRS transmission occur simultaneously in the same subframe, the user equipment may not transmit PUCCH format 2 without ACK/NACK.

(iv)在携带ACK/NACK和调度请求(SR)二者或者之一的PUCCH格式传输和SRS传输在相同子帧中同时发生的情况下，如果由高层限定的参数“ackNackSRS-Simultaneous Transmission”为FALSE时，用户设备可以不传输SRS。在本文中，SRS可以为周期SRS和非周期SRS。(iv) In the case where PUCCH format transmission and SRS transmission carrying both ACK/NACK and scheduling request (SR) or one of them occur simultaneously in the same subframe, if the parameter "ackNackSRS-Simultaneous Transmission" defined by the upper layer is When FALSE, the user equipment may not transmit the SRS. Herein, the SRS can be periodic SRS and aperiodic SRS.

(v)在携带ACK/NACK和正SR二者或者之一的缩短的PUCCH格式传输和SRS传输在相同子帧中同时发生的情况下，如果由高层限定的参数“ackNackSRS-Simultaneous Transmission”为TRUE时，用户设备可以传输SRS和缩短的PUCCH格式二者。在本文中，SRS可以为周期SRS和非周期SRS。(v) In the case where shortened PUCCH format transmission and SRS transmission carrying both ACK/NACK and positive SR and SRS transmission occur simultaneously in the same subframe, if the parameter "ackNackSRS-Simultaneous Transmission" defined by higher layers is TRUE , the user equipment can transmit both the SRS and the shortened PUCCH format. Herein, the SRS can be periodic SRS and aperiodic SRS.

(vi)在使用标准PUCCH格式来携带ACK/NACK和正SR二者或者之一的PUCCH传输和服务小区上的SRS传输在相同子帧中同时发生的情况下，用户设备可以不传输SRS。在本文中，SRS可以为周期SRS和非周期SRS。(vi) In case that PUCCH transmission using standard PUCCH format to carry either or both ACK/NACK and positive SR and SRS transmission on the serving cell occur simultaneously in the same subframe, the user equipment may not transmit SRS. Herein, the SRS can be periodic SRS and aperiodic SRS.

(vii)同时，参数“ackNackSRS-SimultaneousTransmission”可以由高层来提供作为RRC参数。这种RRC参数可以用于确定用户设备是否被配置为支持PUCCH上的HARQ ACK/NACK和SRS在相同子帧中的同时传输。在用户设备被配置为支持PUCCH上的HARQ ACK/NACK和SRS在一个子帧中的同时传输的情况下，如果对应的子帧为鉴于第一小区(例如主小区、主分量载波、P小区)的小区特定SRS子帧，则用户设备可以使用缩短的PUCCH格式来同时传输HARQ ACK/NACK和SRS。这里，缩短的PUCCH格式可以无关乎SRS是否在对应的子帧中被传输而使用。如果对应的子帧不是第一小区的小区特定SRS，则用户设备可以使用标准PUCCH格式1/1a/1b或者标准PUCCH格式3中的一个来执行HARQ ACK/NACK和SRS的传输。(vii) Meanwhile, the parameter "ackNackSRS-SimultaneousTransmission" may be provided by higher layers as an RRC parameter. Such RRC parameters may be used to determine whether the user equipment is configured to support simultaneous transmission of HARQ ACK/NACK and SRS on the PUCCH in the same subframe. In case the user equipment is configured to support simultaneous transmission of HARQ ACK/NACK and SRS on PUCCH in one subframe, if the corresponding subframe is in view of the first cell (e.g. primary cell, primary component carrier, PCell) The cell-specific SRS subframe, the user equipment can use the shortened PUCCH format to transmit HARQ ACK/NACK and SRS at the same time. Here, the shortened PUCCH format may be used irrespective of whether the SRS is transmitted in the corresponding subframe. If the corresponding subframe is not the cell-specific SRS of the first cell, the user equipment may use one of standard PUCCH format 1/1a/1b or standard PUCCH format 3 to perform HARQ ACK/NACK and SRS transmission.

在下文中，将描述用于在上行链路PUCCH上的一个子帧中同时传输ACK/NACK和周期CSI的用户设备的操作。Hereinafter, an operation of a user equipment for simultaneously transmitting ACK/NACK and periodic CSI in one subframe on an uplink PUCCH will be described.

图2是示出根据至少一个实施例的使用PUCCH格式2来同时传输HARQACK/NACK和CSI的示意图。FIG. 2 is a schematic diagram illustrating simultaneous transmission of HARQ ACK/NACK and CSI using PUCCH format 2, according to at least one embodiment.

参照图2(a)，在标准循环前缀(CP)的情况下，可以使用PUCCH格式2来同时传输HARQ ACK/NACK和CSI。在这种情况下，CSI传输信息可以为块码的且使用QPSK来调制。因此，每个子帧可以包括十个符号。前面五个符号可以在第一时隙中传输，并且剩余的五个符号可以在第二时隙中传输。Referring to FIG. 2( a ), in the case of a standard cyclic prefix (CP), PUCCH format 2 can be used to simultaneously transmit HARQ ACK/NACK and CSI. In this case, the CSI transmission information may be block coded and modulated using QPSK. Therefore, each subframe may include ten symbols. The first five symbols may be transmitted in a first slot, and the remaining five symbols may be transmitted in a second slot.

每个时隙可以包括七个DFTS-OFDM符号。在每个时隙中的七个DFTS-DFDM符号中，两个符号可以用于传输上行链路DM-RS。当同时传输HARQ ACK/NACK时，每个时隙中的第二DM-RS可以由HARQ ACK/NACK来调整。BPSK调制方案和QPSK调制方案中的一个可以根据反馈信息是“一位的HARQ ACK/NACK”还是“两位的HARQ ACK/NACK”来使用。在每个时隙中，待传输的五个QPSK符号中的每一个和第二调制的DM-RS符号可以乘以循环移位的长度12的小区特定序列。在本文中，第二调制的DM-RS符号可以为每个时隙中的DM-RS符号中的、由HARQ ACK/NACK调制的第二DM-RS符号。乘法结果可以在对应的DFTS-OFDM符号中传输。Each slot may include seven DFTS-OFDM symbols. Of the seven DFTS-DFDM symbols in each slot, two symbols can be used to transmit uplink DM-RS. When HARQ ACK/NACK is transmitted simultaneously, the second DM-RS in each slot can be adjusted by HARQ ACK/NACK. One of the BPSK modulation scheme and the QPSK modulation scheme may be used according to whether the feedback information is "HARQ ACK/NACK of one bit" or "HARQ ACK/NACK of two bits". In each slot, each of the five QPSK symbols to be transmitted and the second modulated DM-RS symbol may be multiplied by a cyclically shifted length 12 cell-specific sequence. Herein, the second modulated DM-RS symbol may be the second DM-RS symbol modulated by HARQ ACK/NACK among the DM-RS symbols in each slot. The multiplication results can be transmitted in corresponding DFTS-OFDM symbols.

参照图2(b)，在具有每时隙六个DFTS-OFDM符号的扩展循环前缀(CP)的情况下，可以使用相同结构。然而，每个时隙可以包括一个上行链路DM-RS符号而代替两个上行链路DM-RS符号。CSI传输信息和HARQ ACK/NACK可以为块码的且使用QPSK调制方案来调制。因此，每个子帧可以包括十个符号。在这种情况下，前面五个符号可以在第一时隙中传输，并且剩余的五个符号可以在第二时隙中传输。每个时隙中待传输的五个QPSK符号中的每一个乘以循环移位的长度12的小区特定序列。乘法结果可以在对应的DFTS-OFDM符号中传输。Referring to FIG. 2( b ), in case of an extended cyclic prefix (CP) with six DFTS-OFDM symbols per slot, the same structure can be used. However, each slot may include one uplink DM-RS symbol instead of two uplink DM-RS symbols. CSI transmission information and HARQ ACK/NACK may be block coded and modulated using a QPSK modulation scheme. Therefore, each subframe may include ten symbols. In this case, the first five symbols may be transmitted in the first slot, and the remaining five symbols may be transmitted in the second slot. Each of the five QPSK symbols to be transmitted in each slot is multiplied by a cyclically shifted length 12 cell-specific sequence. The multiplication results can be transmitted in corresponding DFTS-OFDM symbols.

例如，参数“simultaneousAckNackAndCQI”可以由高层提供作为RRC参数。这种RRC参数可以用于确定用户设备是否被配置为支持HARQ ACK/NACK和周期CSI在相同子帧中的同时传输。如果用户设备被配置为支持HARQACK/NACK和周期CSI在一个子帧中的同时传输，则用户设备可以使用对应的子帧中的PUCCH格式2a/2b来同时传输HARQ-ACK和周期CSI。For example, the parameter "simultaneousAckNackAndCQI" may be provided by higher layers as an RRC parameter. Such RRC parameters can be used to determine whether the user equipment is configured to support simultaneous transmission of HARQ ACK/NACK and periodic CSI in the same subframe. If the user equipment is configured to support simultaneous transmission of HARQ ACK/NACK and periodic CSI in one subframe, the user equipment may use PUCCH format 2a/2b in the corresponding subframe to simultaneously transmit HARQ-ACK and periodic CSI.

在下文中，将根据是否存在传输功率限制来描述功率控制方法。换言之，在两种情况(例如功率受限情况和非功率受限情况)下，将详细描述用于以载波聚合执行功率控制的方法。具体地，将详细描述用于在载波聚合下执行(i)上行链路传输信道之间的、(ii)上行链路信道和SRS之间的、和/或(iii)SRS之间的功率控制的方法。Hereinafter, a power control method will be described according to whether there is a transmission power limitation. In other words, a method for performing power control with carrier aggregation will be described in detail in two cases such as a power-limited case and a non-power-limited case. Specifically, a method for performing power control (i) between uplink transport channels, (ii) between uplink channels and SRSs, and/or (iii) between SRSs under carrier aggregation will be described in detail. Methods.

在用户设备被配置为支持PUCCH和PUSCH的同时传输的情况下，如果用户设备的总传输功率超过则用户设备可以首先确定用于PUCCH的传输功率，并且然后确定剩余可用的传输功率内的、用于服务小区(“c”)的对应的PUSCH的传输功率。在这种情况下，用户设备可以通过将PUSCH传输功率按比例缩放为“0”和“1”之间的数值来确定PUSCH传输功率(即PUSCH的传输功率)。In the case that the user equipment is configured to support simultaneous transmission of PUCCH and PUSCH, if the total transmission power of the user equipment exceeds The user equipment may then first determine the transmission power for the PUCCH, and then determine the transmission power for the corresponding PUSCH of the serving cell ("c") within the remaining available transmission power. In this case, the user equipment can determine the PUSCH transmission power (that is, the transmission power of the PUSCH) by scaling the PUSCH transmission power to a value between "0" and "1".

在上述的情形下，用户设备可以根据下面的公式1来确定对应的PUSCH的传输功率。用户设备可以按比例缩放子帧i中的用于服务小区(“c”)的使得满足下面的公式1的条件。In the above situation, the user equipment may determine the transmission power of the corresponding PUSCH according to the following formula 1. The user equipment may scale the cell ("c") for the serving cell ("c") in subframe i so that the condition of Formula 1 below is satisfied.

[公式1][Formula 1]

在公式1中，表示P_PUCCH(i)的线性值，并且表示P_PUSCH，c(i)的线性值。表示子帧i中的UE总配置的最大输出功率P_CMAX的线性值。w(i)表示用于服务小区c的的比例因子，其中，0≤w(i)≤1。在子帧i中不存在PUCCH传输的情况下，In Equation 1, represents the linear value of P_PUCCH (i), and Represents the linear value of P_PUSCH,c (i). Indicates the linear value of the total configured maximum output power P_CMAX of the UE in subframe i. w(i) represents the The scaling factor of , where 0≤w(i)≤1. In case there is no PUCCH transmission in subframe i,

同时，如果用户设备的总传输功率超过则用户设备可以根据对应的PUSCH是否包括上行链路控制信息(UCI)来确定在不同分量载波或者不同服务小区上传输的、PUSCH之间的传输功率。更具体而言，用户设备可以以这样的方式执行PUSCH传输功率分配：与“具有UCI的PUSCH传输”相关联的服务小区或者分量载波具有较高优先级。在这种情况下，用于“不具有UCI的PUSCH”的传输功率可以使用剩余的服务小区之间或者分量载波之间的同一比例因子通过执行功率比例缩放来确定。At the same time, if the total transmission power of the user equipment exceeds Then the user equipment can determine the transmission power between PUSCHs transmitted on different component carriers or different serving cells according to whether the corresponding PUSCH includes uplink control information (UCI). More specifically, the user equipment may perform PUSCH transmission power allocation in such a way that the serving cell or component carrier associated with "PUSCH transmission with UCI" has a higher priority. In this case, the transmission power for "PUSCH without UCI" can be determined by performing power scaling using the same scaling factor between remaining serving cells or component carriers.

在上述情形中，用户设备可以根据下面的公式2来确定用于对应的PUSCH的传输功率。如果用户设备具有服务小区j上的具有UCI的PUSCH传输、以及一个或者多个剩余的服务小区中的任一个服务小区中的不具有UCI的PUSCH传输，并且如果用户设备的总传输功率超过则用户设备可以针对子帧i中的不具有UCI的服务小区按比例缩放使得满足下面的公式2的条件。In the above situation, the user equipment may determine the transmission power for the corresponding PUSCH according to Formula 2 below. If the user equipment has PUSCH transmission with UCI on serving cell j and PUSCH transmission without UCI in any one of the one or more remaining serving cells, and if the total transmission power of the user equipment exceeds Then the user equipment can scale for the serving cell without UCI in subframe i so that the condition of Formula 2 below is satisfied.

在公式2中，表示用于具有UCI的小区的PUSCH传输功率，并且w(i)为用于不具有UCI的服务小区c的的比例因子。在这种情况下，除非且用户设备的总传输功率超过否则没有功率比例缩放可以应用于而且，当w(i)＞0时，w(i)值在服务小区之间为相同的，但是针对一个或者多个特定服务小区，w(i)可能为“0”。In Equation 2, denotes the PUSCH transmission power for a cell with UCI, and w(i) is for the serving cell c without UCI scale factor. In this case, unless And the total transmission power of the user equipment exceeds Otherwise no power scaling can be applied to Also, when w(i) > 0, the w(i) value is the same among serving cells, but w(i) may be "0" for one or more specific serving cells.

同时，如果用户设备的总传输功率超过则用户设备可以执行在不同分量载波或者不同服务小区上传输的“具有UCI的PUCCH/PUSCH传输(即具有UCI的同时的PUCCH和PUSCH传输)”和“不具有UCI的PUSCH传输”之间的传输功率分配。更具体而言，用户设备可以以这样方式执行传输功率分配：(i)首先保证PUCCH传输功率，并且(ii)第二保证具有UCI的PUSCH传输功率。在这种情况下，可以为不具有UCI的PUSCH分配剩余的传输功率。即，用于不具有UCI的PUSCH的传输功率可以使用剩余的服务小区之间或者分量载波之间的同一比例因子通过执行功率比例缩放来确定。在本文中，用于一个或者多个特定服务小区或者一个或者多个分量载波的比例因子可以设置为“0”。At the same time, if the total transmission power of the user equipment exceeds Then the user equipment can perform transmission between "PUCCH/PUSCH transmission with UCI (ie simultaneous PUCCH and PUSCH transmission with UCI)" and "PUSCH transmission without UCI" transmitted on different component carriers or different serving cells power distribution. More specifically, the user equipment may perform transmission power allocation in such a manner that (i) PUCCH transmission power is guaranteed first, and (ii) PUSCH transmission power with UCI is guaranteed second. In this case, the remaining transmission power can be allocated for PUSCH without UCI. That is, the transmission power for PUSCH without UCI may be determined by performing power scaling using the same scaling factor between remaining serving cells or component carriers. Herein, the scale factor for one or more specific serving cells or one or more component carriers may be set to '0'.

在上述情形中，用户设备可以根据下面的公式3来确定对应的PUSCH的传输功率。如果用户设备具有服务小区j上的具有UCI的同时的PUCCH和PUSCH传输、以及一个或者多个剩余的服务小区中任一个服务小区中的不具有UCI的PUSCH传输，并且如果用户设备的总传输功率超过则用户设备可以根据下面的公式3来获得In the above situation, the user equipment may determine the transmission power of the corresponding PUSCH according to Formula 3 below. If the user equipment has simultaneous PUCCH and PUSCH transmission with UCI on serving cell j, and PUSCH transmission without UCI in any one of the one or more remaining serving cells, and if the total transmission power of the user equipment Exceed Then the user equipment can be obtained according to the following formula 3

同时，如果用户设备的总传输功率超过则用户设备可以执行在与不同分量载波或者不同服务小区相关联的SRS之间的传输功率分配。更具体而言，用于SRS的传输功率可以使用剩余的服务小区之间或者分量载波之间的同一比例因子通过执行功率比例缩放来确定。At the same time, if the total transmission power of the user equipment exceeds The user equipment may then perform transmission power allocation between SRSs associated with different component carriers or different serving cells. More specifically, the transmission power for SRS may be determined by performing power scaling using the same scaling factor between remaining serving cells or component carriers.

在上述情形中，用户设备可以根据下面的公式4来确定对应的SRS的传输功率。如果用于SRS的用户设备的总传输功率超过则用户设备按比例缩放子帧i中的用于服务小区c的使得满足下面的公式4的条件。In the above situation, the user equipment may determine the transmission power of the corresponding SRS according to Formula 4 below. If the total transmission power of the user equipment used for SRS exceeds Then the user equipment scales the subframe i for the serving cell c so that the condition of Formula 4 below is satisfied.

在公式4中，表示P_SRS，c(i)的线性值，并且表示子帧i中的P_CMAX的线性值。w(i)表示用于服务小区c的的比例因子，其中，0≤w(i)≤1。在本文中，w(i)值可以在服务小区之间是相同的。In Equation 4, represents the linear value of_{PSRS, c} (i), and Indicates the linear value of_PCMAX in subframe i. w(i) represents the The scaling factor of , where 0≤w(i)≤1. Herein, the w(i) value may be the same among serving cells.

同时，在应用载波聚合的情况下，用户设备可以向传输/接收点同时传输上行链路信道(例如上行链路数据信道和/或上行链路控制信道)和上行链路信号(例如SRS)。在这种情况下，用户设备的单个传输时间提前量(TA)值(即与单个值对应的传输TA值)可以同一地应用于所有不同分量载波或者所有不同服务小区。在本文中，传输TA值可以从传输/接收点中指出。在应用单个TA的情况下，与上行链路信道之间的复用和/或功率控制相关联的上述方法可以用作用户设备的操作。Meanwhile, in the case of applying carrier aggregation, the user equipment can simultaneously transmit uplink channels (eg, uplink data channel and/or uplink control channel) and uplink signals (eg, SRS) to the transmission/reception point. In this case, a single transmission timing advance (TA) value of the user equipment (ie a transmission TA value corresponding to a single value) can be applied identically to all different component carriers or all different serving cells. Herein, the transmission TA value can be indicated from the transmission/reception point. In case a single TA is applied, the above-described methods associated with multiplexing and/or power control between uplink channels may be used as the operation of the user equipment.

典型地，对于相同分量载波和/或不同分量载波而言通常不支持在相同符号中的上行链路信道(例如上行链路数据信道和/或上行链路控制信道)和SRS的同时传输。在这种情况下，如图3所示，如果应用单个TA，则可以有效阻止上行链路信道(例如上行链路数据信道和/或上行链路控制信道)和SRS之间的符号重叠。Typically, simultaneous transmission of uplink channels (eg, uplink data channels and/or uplink control channels) and SRS in the same symbol is not supported for the same component carrier and/or different component carriers. In this case, as shown in FIG. 3, if a single TA is applied, symbol overlap between uplink channels (eg, uplink data channels and/or uplink control channels) and SRSs can be effectively prevented.

然而，在针对用户设备指出多个传输TA值的情况下，可能需要不同分量载波(或者服务小区)或者分量载波组(或者服务小区组)上的上行链路信道和上行链路信号之间的复用和/或功率控制方法与在单个TA的情况下的复用和/或功率控制方法不同。换言之，一个子帧中的上行链路SC-FDMA符号的边界可能不在不同分量载波(或者服务小区)之间或者不同分量载波组(或者服务小区组)之间准确同时发生。由于这个原因，可能存在当对应的用户设备传输上行链路(例如上行链路数据信道和/或上行链路控制信道)和上行链路信号时的不定性。因此，传输/接收点和对应的用户设备可能不必识别如何执行对应的用户设备的操作。However, in case multiple transmission TA values are indicated for the user equipment, it may be necessary to communicate between uplink channels and uplink signals on different component carriers (or serving cells) or groups of component carriers (or groups of serving cells). The multiplexing and/or power control method is different from that in the case of a single TA. In other words, the boundaries of uplink SC-FDMA symbols in one subframe may not occur exactly simultaneously between different component carriers (or serving cells) or between different component carrier groups (or serving cell groups). For this reason, there may be ambiguities when the corresponding user equipment transmits uplink (eg uplink data channel and/or uplink control channel) and uplink signals. Therefore, the transmission/reception point and the corresponding user equipment may not have to identify how to perform the operation of the corresponding user equipment.

换言之，如图4所示，在指出用于用户设备的多个TA值的情况下，可能存在不同分量载波(或者服务小区)之间或者不同分量载波组(或者服务小区组)之间的上行链路信道(例如上行链路数据信道和/或上行链路控制信道)和SRS的重叠或者冲突问题(例如符号重叠和/或一个符号内的重叠或者冲突)。例如，在CC0(Pcell)和CC1(Scell)被配置有不同时间提前量组(TAG)(例如TAG0，TAG1)的情况下，可能在区域“410”和“420”处存在与用户设备的上行链路传输(例如上行链路信道和上行链路信号的传输)相关联的不定性。因此，在传输/接收点中也可能存在与上行链路接收(上行链路信道和上行链路信号的接收)相关联的不定性。In other words, as shown in Figure 4, in the case of indicating multiple TA values for the user equipment, there may be uplink between different component carriers (or serving cells) or between different component carrier groups (or serving cell groups) Overlap or collision issues of link channels (eg, uplink data channel and/or uplink control channel) and SRS (eg, symbol overlap and/or overlap or collision within a symbol). For example, in the case that CC0 (Pcell) and CC1 (Scell) are configured with different timing advance groups (TAG) (such as TAG0, TAG1), there may be uplink with the user equipment at areas "410" and "420". Uncertainties associated with link transmissions such as transmission of uplink channels and uplink signals. Consequently, there may also be ambiguities associated with uplink reception (reception of uplink channels and uplink signals) in the transmission/reception point.

因此，在用户设备被配置有多个TAG的情况下，可能需要限定与由用户设备传输的上行链路信道(例如上行链路数据信道和/或上行链路控制信道)和上行链路信号相关联的复用和功率控制方法。Therefore, in the case that the user equipment is configured with multiple TAGs, it may be necessary to define Linked multiplexing and power control methods.

本实施例涉及在施加载波聚合的情况下的与由用户设备在上行链路上传输的控制信道相关联的传输和复用方法。此外，本实施例涉及一种用于复用上行链路控制信道和SRS的方法和设备。具体地，在采用多个TAG的情况下，本实施例可以提供(i)上行链路控制信道和SRS之间和(ii)SRS之间的复用和传输。The present embodiment relates to a transmission and multiplexing method associated with a control channel transmitted by a user equipment on the uplink with carrier aggregation applied. Furthermore, the present embodiment relates to a method and device for multiplexing an uplink control channel and an SRS. Specifically, in the case of using multiple TAGs, this embodiment can provide (i) multiplexing and transmission between the uplink control channel and the SRS and (ii) between the SRS.

更具体而言，在要由用户设备传输的上行链路信道(例如上行链路控制信道和/或上行链路数据信道)和SRS在载波聚合下处于与多个TAG相关联的不同分量载波上的情况下，可能需要最新定义用户设备的操作。More specifically, when the uplink channel (e.g. uplink control channel and/or uplink data channel) and the SRS to be transmitted by the user equipment are on different component carriers associated with multiple TAGs under carrier aggregation In some cases, it may be necessary to up-to-date define the operation of the user device.

而且，在配置多个TAG的情况下，本实施例可以定义用户设备的操作，使得支持向后兼容性。同时，如果不需要支持向后兼容性，则本实施例可能定义用户设备的最新操作。Moreover, in the case of configuring multiple TAGs, this embodiment can define the operation of the user equipment so as to support backward compatibility. At the same time, the present embodiment may define the latest operation of the user equipment if backward compatibility is not required to be supported.

在这种情况下，虽然传输/接收形成了用于用户设备的多个TAG，但是如果用户设备的操作与两个或者更多个上行链路分量载波相关联，则特定分量载波可以属于相同TAG。例如，在形成了两个上行链路分量载波的情况下，每个上行链路分量载波可以属于相同TAG。针对另一个示例，在形成三个上行链路分量载波的情况下，两个上行链路分量载波可以属于相同TAG，并且其它上行链路分量载波可以属于另一个TAG(即不同的TAG)。In this case, although transmission/reception forms a plurality of TAGs for the user equipment, if the operation of the user equipment is associated with two or more uplink component carriers, a specific component carrier may belong to the same TAG . For example, where two uplink component carriers are formed, each uplink component carrier may belong to the same TAG. For another example, where three uplink component carriers are formed, two uplink component carriers may belong to the same TAG and the other uplink component carriers may belong to another TAG (ie a different TAG).

因此，当考虑上述情节时，在与上行链路信道(例如上行链路控制信道和/或上行链路数据信道)和SRS的传输相关联的分量载波属于相同TAG的情况下，用户设备的操作可以被定义为使得用户设备根据与单个TA相关联来定义的上行链路信道/SRS传输方法(即上行链路控制/数据信道和SRS的传输方法)来操作。Therefore, when the above scenario is considered, the operation of the user equipment in case the component carriers associated with the transmission of the uplink channel (e.g. uplink control channel and/or uplink data channel) and the SRS belong to the same TAG, the operation of the user equipment may be defined such that the user equipment operates according to an uplink channel/SRS transmission method (ie, a transmission method of an uplink control/data channel and an SRS) defined in association with a single TA.

典型地，通常仅支持单个TA。然而，即使在形成多个TAG的情况下，为了保证向后兼容性，被形成属于相同TAG的分量载波的用户设备的操作也可以根据要由用户设备传输的传输功率是否受限(即根据对应于功率受限情形或者非功率受限情形)来确定(或者定义)，如稍后所述。Typically, only a single TA is usually supported. However, even in the case of forming a plurality of TAGs, in order to ensure backward compatibility, the operation of the user equipment formed of component carriers belonging to the same TAG may be based on whether the transmission power to be transmitted by the user equipment is limited (ie, according to the corresponding be determined (or defined) in a power-constrained situation or a non-power-constrained situation), as described later.

首先，在(i)不同分量载波属于相同TAG或者属于不同TAG的不同分量载波完全重叠，(ii)期望PUCCH/PUSCH和SRS的同时传输，以及(iii)传输功率受限的情况(“情况1”)下，用户设备的操作可以被定义如下。First, in cases where (i) different component carriers belonging to the same TAG or different component carriers belonging to different TAGs completely overlap, (ii) simultaneous transmission of PUCCH/PUSCH and SRS is desired, and (iii) transmission power is limited (“Case 1 ”), the operation of the user equipment may be defined as follows.

对于PUCCH和SRS的同时传输(在本文中称为“PUCCH+SRS”)而言，如果PUCCH格式2传输与非周期SRS传输重叠，则用户设备的操作可以被定义以传输非周期SRS。否则，用户设备可以被定义以总是放弃SRS。For simultaneous transmission of PUCCH and SRS (referred to herein as "PUCCH+SRS"), if PUCCH format 2 transmission overlaps with aperiodic SRS transmission, the operation of the user equipment may be defined to transmit aperiodic SRS. Otherwise, the user equipment can be defined to always drop the SRS.

对于PUSCH和SRS的同时传输(在本文中称为“PUSCH+SRS”)而言，如果PUSCH包括UCI，则用户设备的操作可以被定义为使得具有UCI的PUSCH的传输功率首先被保证且剩余的传输功率用于SRS传输。在这种情况下，如果不存在用于SRS传输的剩余的传输功率，则用户设备可以放弃SRS。For simultaneous transmission of PUSCH and SRS (referred to as "PUSCH+SRS" herein), if the PUSCH includes UCI, the operation of the user equipment can be defined such that the transmission power of the PUSCH with UCI is guaranteed first and the remaining The transmission power is used for SRS transmission. In this case, if there is no remaining transmission power for SRS transmission, the user equipment may drop the SRS.

对于PUCCH、PUSCH和SRS的同时传输(在本文中称为“PUCCH+PUSCH+SRS”)而言，如果PUCCH格式2传输与非周期SRS传输重叠，则用户设备的操作可以被定义为使得传输PUSCH和非周期SRS。对于PUSCH和非周期SRS的传输功率而言，如果PUSCH包括UCI，则用户设备的操作可以被定义为使得具有UCI的PUSCH的传输功率首先被保证且剩余的传输功率用于非周期SRS传输。For simultaneous transmission of PUCCH, PUSCH and SRS (referred to herein as "PUCCH+PUSCH+SRS"), if PUCCH format 2 transmission overlaps with aperiodic SRS transmission, the operation of the user equipment can be defined such that the transmission of PUSCH and aperiodic SRS. Regarding the transmission power of PUSCH and aperiodic SRS, if the PUSCH includes UCI, the operation of the user equipment can be defined such that the transmission power of PUSCH with UCI is guaranteed first and the remaining transmission power is used for aperiodic SRS transmission.

而且，在这种情况下，无关乎PUSCH是否包括UCI，用户设备的操作可以被定义以传输PUSCH，此处，对应的子帧中的为SRS传输保留的最后符号被打孔使得为SRS传输保留的最后符号未被映射到用于PUSCH的资源单元。换言之，在用户设备被配置有多个TAG且执行SRS和PUSCH在相同小区上的同时传输的情况下，用户设备可以被定义为使得传输PUSCH的子帧的最后符号未被映射到PUSCH的资源单元。此后，可以参照图5和图6如实施例1来详细描述上述实施例。Also, in this case, irrespective of whether the PUSCH includes UCI, the operation of the user equipment can be defined to transmit the PUSCH, where the last symbol reserved for SRS transmission in the corresponding subframe is punctured so that it is reserved for SRS transmission The last symbol of is not mapped to resource elements for PUSCH. In other words, in the case where a user equipment is configured with multiple TAGs and performs simultaneous transmission of SRS and PUSCH on the same cell, the user equipment can be defined such that the last symbol of a subframe in which PUSCH is transmitted is not mapped to a resource element of PUSCH . Hereinafter, the above-mentioned embodiment can be described in detail as Embodiment 1 with reference to FIGS. 5 and 6 .

在除了这种情况之外，用户设备的操作可以被定义为总是放弃SRS。这里，对应的子帧可以为UE特定非周期SRS子帧或者小区特定SRS子帧。更具体而言，用户设备可以被配置有多个TAG且执行SRS和PUSCH/PUCCH在不同小区上的同时传输。在这种情况下，如果针对给定的服务小区在子帧(例如子帧i)上的符号中的用户设备的SRS传输与针对一个或者多个不同服务小区的在子帧(例如子帧i或者子帧i+l)上的PUCCH/PUSCH传输重叠，并且如果其总传输功率在该符号的任何重叠部分上超过P_CMAX，则用户设备可以放弃与SRS传输相关联的子帧(例如子帧i)中的SRS。此后，可以参照图7和图8如实施例2来详细描述上述实施例。In addition to this case, the operation of the user equipment may be defined to always discard the SRS. Here, the corresponding subframe may be a UE-specific aperiodic SRS subframe or a cell-specific SRS subframe. More specifically, user equipment may be configured with multiple TAGs and perform simultaneous transmission of SRS and PUSCH/PUCCH on different cells. In this case, if the user equipment's SRS transmission in a symbol on a subframe (eg subframe i) for a given serving cell is different from that for one or more different serving cells in a subframe (eg subframe i Or the PUCCH/PUSCH transmissions on subframe i+1) overlap, and if their total transmission power exceeds_PCMAX on any overlapping part of the symbol, the user equipment can abandon the subframe associated with the SRS transmission (e.g. subframe SRS in i). Hereinafter, the above-mentioned embodiment can be described in detail with reference to FIG. 7 and FIG. 8 as Embodiment 2. FIG.

对于SRS和另一个SRS的同时传输(在本文中称为“SRS+SRS”)而言，用户设备可以使用同一比例缩放值(即同一比例因子)通过执行功率比例缩放来确定SRS传输功率，使得用户设备可以以典型方式来操作(即使得用户设备根据典型的或者现有的UE行为来操作)。更具体而言，在这种情况下，如果(i)用户设备被配置有多个TAG且(ii)存在传输功率限制(即总传输功率在与SRS传输相关联的符号之间的任何重叠部分上超过用户设备的最大可允许传输功率(P_CMAX))，则当针对不同小区同时传输“SRS和另一个SRS”(“SRS+SRS”)时用户设备可以使用同一比例因子通过执行功率比例缩放来确定SRS传输功率。此后，可以参照图9和图10如实施例3来详细描述上述实施例。For simultaneous transmission of an SRS and another SRS (referred to herein as "SRS+SRS"), the user equipment can determine the SRS transmission power by performing power scaling using the same scaling value (ie, the same scaling factor), such that The user equipment may operate in a typical manner (ie such that the user equipment operates according to typical or existing UE behavior). More specifically, in this case, if (i) the user equipment is configured with multiple TAGs and (ii) there is a transmission power limitation (i.e. any overlap of total transmission power between symbols associated with SRS transmission exceeds the maximum allowable transmission power of the user equipment (P_CMAX )), then the user equipment can use the same scaling factor when transmitting "SRS and another SRS"("SRS+SRS") simultaneously for different cells by performing power scaling to determine the SRS transmission power. Hereinafter, the above-mentioned embodiment can be described in detail with reference to FIG. 9 and FIG. 10 as Embodiment 3. FIG.

第二，在(i)不同分量载波属于相同TAG或者属于不同TAG的不同分量载波完全重叠，(ii)期望PUCCH/PUSCH和SRS的同时传输，以及(iii)不存在传输功率受限的情况(“情况2”)下，用户设备的操作可以被定义为使得用户设备根据参照公式1到公式4描述的UE操作来操作。Second, when (i) different component carriers belonging to the same TAG or different component carriers belonging to different TAGs completely overlap, (ii) simultaneous transmission of PUCCH/PUSCH and SRS is expected, and (iii) there is no transmission power limitation ( In "Case 2"), the operation of the user equipment may be defined such that the user equipment operates according to the UE operation described with reference to Equation 1 to Equation 4.

第三，在(i)属于不同TAG的不同分量载波不完全重叠(即部分地重叠)，(ii)期望PUCCH/PUSCH和SRS的同时传输，以及(iii)存在传输功率受限的情况(“情况3”)下，用户设备的操作可以被定义如下。Third, when (i) different component carriers belonging to different TAGs do not completely overlap (i.e. partially overlap), (ii) simultaneous transmission of PUCCH/PUSCH and SRS is expected, and (iii) there is a case of transmission power limitation (“ Case 3"), the operation of the user equipment can be defined as follows.

对于PUCCH+SRS(即PUCCH和SRS的同时传输)而言，用户设备可以放弃对应的分量载波上的SRS且仅传输PUCCH。For PUCCH+SRS (ie simultaneous transmission of PUCCH and SRS), the user equipment may abandon SRS on the corresponding component carrier and transmit only PUCCH.

对于PUSCH+SRS(即PUSCH和SRS的同时传输)而言，用户设备可以放弃对应的分量载波上的SRS且仅传输PUSCH。For PUSCH+SRS (ie simultaneous transmission of PUSCH and SRS), the user equipment may abandon SRS on the corresponding component carrier and only transmit PUSCH.

对于PUCCH+PUSCH+SRS(即PUCCH、PUSCH和SRS的同时传输)而言，用户设备可以放弃对应的分量载波上的SRS，并且根据用于同时传输PUCCH和PUSCH(“PUCCH+PUSCH”)的传输功率确定方法来传输PUCCH和PUSCH。如实施例2所述，在用户设备被配置有多个TAG并且完全或者部分重叠处于不同TAG中的情况下，可以执行在不同小区中的SRS和PUSCH/PUCCH的同时传输。在这种情况下，如果总传输功率在不同小区上传输SRS和PUCCH/PUSCH的符号之间的任何重叠部分上超过用户设备的最大可允许的传输功率(P_CMAX)，则用户设备可以放弃与SRS传输相关联的子帧中的SRS。更具体而言，如果针对给定的服务小区在子帧(例如子帧i)上的符号中的用户设备的SRS传输与针对一个或者多个不同服务小区的在子帧(例如子帧i或者子帧i+l)上的PUCCH/PUSCH传输重叠，并且如果其总传输功率在该符号的任何重叠部分上超过P_CMAX，则用户设备可以放弃与SRS传输相关联的子帧(例如子帧i)中的SRS。For PUCCH+PUSCH+SRS (i.e. simultaneous transmission of PUCCH, PUSCH and SRS), the user equipment may forego SRS on the corresponding Power determination method to transmit PUCCH and PUSCH. As described in Embodiment 2, in the case that the user equipment is configured with multiple TAGs and is completely or partially overlapped in different TAGs, simultaneous transmission of SRS and PUSCH/PUCCH in different cells can be performed. In this case, if the total transmission power exceeds the maximum allowable transmission power (P_CMAX ) of the user equipment on any overlap between the symbols transmitting SRS and PUCCH/PUSCH on different cells, the user equipment may forego the communication with The SRS transmits the SRS in the associated subframe. More specifically, if the user equipment's SRS transmission in a symbol on a subframe (eg, subframe i) for a given serving cell is different from that for one or more different serving cells in a subframe (eg, subframe i or The PUCCH/PUSCH transmissions on subframe i+1) overlap, and if their total transmission power exceeds_PCMAX on any overlapping part of the symbol, the user equipment can abandon the subframe associated with the SRS transmission (such as subframe i SRS in ).

对于SRS+SRS(即SRS和另一个SRS的同时传输)而言，用户设备可以使用同一比例缩放值(即同一比例因子)通过执行功率比例缩放来确定SRS传输功率，使得用户设备可以以典型方式来操作(即使得用户设备根据典型的或者现有的UE行为来操作)。如实施例3所述，如果(i)用户设备被配置有多个TAG且(ii)存在传输功率限制(即总传输功率在与SRS传输相关联的符号之间的任何重叠部分上超过用户设备的最大可允许传输功率(P_CMAX))，则当针对不同小区同时传输SRS和另一个SRS时用户设备可以使用同一比例因子通过执行功率比例缩放来确定SRS传输功率。For SRS+SRS (i.e. simultaneous transmission of an SRS and another SRS), the user equipment can determine the SRS transmission power by performing power scaling using the same scaling value (i.e. the same scaling factor), so that the user equipment can typically to operate (that is, to make the user equipment operate according to typical or existing UE behavior). As described in Embodiment 3, if (i) the user equipment is configured with multiple TAGs and (ii) there is a transmission power limitation (that is, the total transmission power exceeds the user equipment on any overlap between symbols associated with SRS transmission maximum allowable transmission power (P_CMAX )), then the user equipment can determine the SRS transmission power by performing power scaling using the same scaling factor when simultaneously transmitting an SRS and another SRS for different cells.

第四，在(i)属于不同TAG的不同分量载波不完全重叠(即部分地重叠)，(ii)期望PUCCH/PUSCH和SRS的同时传输，以及(iii)不存在传输功率受限的情况(“情况4”)下，用户设备的操作可以被定义如下。Fourth, when (i) different component carriers belonging to different TAGs do not completely overlap (i.e. partially overlap), (ii) simultaneous transmission of PUCCH/PUSCH and SRS is desired, and (iii) there is no transmission power limitation ( Under "Case 4"), the operation of the user equipment can be defined as follows.

对于PUCCH+SRS(即PUCCH和SRS的同时传输)而言，用户设备可以在旨在用于SRS传输的分量载波上连同PUCCH传输一起来传输SRS。For PUCCH+SRS (ie simultaneous transmission of PUCCH and SRS), the user equipment may transmit SRS along with PUCCH transmission on component carriers intended for SRS transmission.

对于PUSCH+SRS(即PUSCH和SRS的同时传输)而言，用户设备可以在旨在用于SRS传输的分量载波上连同PUSCH传输一起来传输SRS。For PUSCH+SRS (ie simultaneous transmission of PUSCH and SRS), the user equipment may transmit SRS along with PUSCH transmission on component carriers intended for SRS transmission.

对于PUCCH+PUSCH+SRS(即PUCCH、PUSCH和SRS的同时传输)而言，用户设备可以在旨在用于SRS传输的分量载波上连同PUCCH传输和PUSCH传输一起来传输SRS。For PUCCH+PUSCH+SRS (ie simultaneous transmission of PUCCH, PUSCH and SRS), the user equipment may transmit SRS together with PUCCH transmission and PUSCH transmission on component carriers intended for SRS transmission.

对于SRS+SRS(即SRS和另一个SRS的同时传输)而言，用户设备可以使用同一比例缩放值(即同一比例因子)通过执行功率缩放来确定SRS传输功率，使得用户设备可以以典型方式来操作(即使得用户设备根据典型的或者现有的UE行为来操作)。For SRS+SRS (i.e. simultaneous transmission of SRS and another SRS), the user equipment can determine the SRS transmission power by performing power scaling using the same scaling value (i.e. the same scaling factor), so that the user equipment can typically Operation (i.e. making the user equipment operate according to typical or existing UE behavior).

图5是示出根据实施例1的用于在用户设备中控制上行链路功率的方法的流程图。图6是示出根据实施例1的用于在用户设备中控制上行链路功率的概念的示意图。FIG. 5 is a flowchart illustrating a method for controlling uplink power in a user equipment according to Embodiment 1. Referring to FIG. FIG. 6 is a schematic diagram illustrating a concept for controlling uplink power in a user equipment according to Embodiment 1. Referring to FIG.

参照图5，根据实施例1的用于在用户设备中控制上行链路功率的方法(500)可以包括：(i)在步骤S510处配置多个TAG并且(ii)在步骤S520处执行上行链路资源映射。Referring to FIG. 5, the method (500) for controlling uplink power in user equipment according to Embodiment 1 may include: (i) configuring multiple TAGs at step S510 and (ii) performing uplink power at step S520 Road resource mapping.

在步骤S510处，用户设备可以由传输/接收点(例如基站)被配置有多个TAG。用户设备可以从传输/接收点接收与多个TAG相关联的配置信息(例如TAG配置信息)，并且配置(或者形成)多个TAG。例如，可以从传输/接收点通过下行链路控制信息(例如PDCCH)或者高层信令(例如RRC消息)向用户设备传输TAG配置信息。At step S510, the user equipment may be configured with multiple TAGs by a transmission/reception point (such as a base station). The user equipment may receive configuration information (for example, TAG configuration information) associated with a plurality of TAGs from a transmission/reception point, and configure (or form) the plurality of TAGs. For example, the TAG configuration information may be transmitted from the transmission/reception point to the user equipment through downlink control information (such as PDCCH) or high layer signaling (such as RRC message).

在步骤S520处，在SRS和PUSCH在相同小区上的同时传输的情况下，用户设备可以执行上行链路资源映射，使得用于PUSCH的资源单元被映射到除了为子帧中的SRS传输分配的最后符号之外的SC-FDMA符号。At step S520, in case of simultaneous transmission of SRS and PUSCH on the same cell, the user equipment may perform uplink resource mapping such that resource elements for PUSCH are mapped to SC-FDMA symbols other than the last symbol.

换言之，如图6所示，在形成多个TAG(例如TAG0和TAG1)的情况下，如果用户设备被定义为在与传输PUSCH的小区相同的小区中传输相同子帧中的SRS，则可以针对于PUSCH传输相关联的最后符号执行速率匹配。在这种情况下，如图6(a)所示，当应用多个TAG时，可以完全重叠不同分量载波(例如CC0，CC1)之间或者分量载波组之间的上行链路信道(例如上行链路数据信道和/或上行链路控制信道)和SRS。可替换地，如图6(b)所示，在应用多个TAG时，可以部分重叠不同分量载波(例如CC0，CC1)之间或者不同分量载波组之间的上行链路信道(例如上行链路数据信道和/或上行链路控制信道)和SRS。In other words, as shown in FIG. 6, in the case of forming multiple TAGs (such as TAG0 and TAG1), if the user equipment is defined to transmit SRS in the same subframe in the same cell as the PUSCH transmission cell, it can be used for Rate matching is performed on the last symbol associated with the PUSCH transmission. In this case, as shown in Figure 6(a), when multiple TAGs are applied, the uplink channels (e.g. uplink Link Data Channel and/or Uplink Control Channel) and SRS. Alternatively, as shown in Figure 6(b), when multiple TAGs are applied, uplink channels between different component carriers (such as CC0, CC1) or between different component carrier groups (such as uplink data channel and/or uplink control channel) and SRS.

在本文中，“小区”可以为一个分量载波。SRS可以为周期SRS和非周期SRS中的一个。Herein, a "cell" may be a component carrier. The SRS may be one of a periodic SRS and an aperiodic SRS.

更具体而言，在PUSCH被映射到物理资源的情况下，到与为PUSCH传输分配的物理资源块(或者多个物理资源块)对应的时间频率资源单元(k,l)的映射可能不用于为相同服务小区中的UE特定周期SRS的可能SRS传输保留的SC-FDMA符号。换言之，无关乎PUSCH是否包括UCI，用户设备的操作可以被定义为传输PUSCH，此处，对应的子帧中的、为SRS传输保留的最后符号被打孔，使得为SRS传输保留的最后符号未被映射到用于PUSCH的资源单元。More specifically, in the case where PUSCH is mapped to physical resources, the mapping to time-frequency resource units (k,l) corresponding to a physical resource block (or multiple physical resource blocks) allocated for PUSCH transmission may not be used for SC-FDMA symbols reserved for possible SRS transmission of UE-specific periodic SRS in the same serving cell. In other words, regardless of whether the PUSCH includes UCI, the operation of the user equipment can be defined as transmitting the PUSCH, where the last symbol reserved for SRS transmission in the corresponding subframe is punctured so that the last symbol reserved for SRS transmission is not are mapped to resource elements for PUSCH.

图7是示出根据实施例2的用于在用户设备中控制上行链路功率的方法的流程图。图8是示出根据实施例2的用于在用户设备中控制上行链路功率的概念的示意图。FIG. 7 is a flowchart illustrating a method for controlling uplink power in a user equipment according to Embodiment 2. Referring to FIG. FIG. 8 is a schematic diagram illustrating a concept for controlling uplink power in a user equipment according to Embodiment 2. Referring to FIG.

参照图7，根据实施例2的用于在用户设备中控制上行链路功率的方法(700)可以包括(i)在步骤S710处配置(或者形成)多个TAG并且(ii)在步骤S720处控制上行链路功率。Referring to FIG. 7, the method (700) for controlling uplink power in user equipment according to Embodiment 2 may include (i) configuring (or forming) a plurality of TAGs at step S710 and (ii) at step S720 Controls uplink power.

在步骤S710处，用户设备可以通过传输/接收点(例如基站)而被配置有多个TAG。用户设备可以从传输/接收点接收与多个TAG相关联的配置信息(例如，TAG配置信息)，并且配置(或者形成)多个TAG。例如，可以通过下行链路控制信息(例如PDCCH)或者高层信令(例如RRC消息)将TAG配置信息从传输/接收点传输到用户设备。At step S710, the user equipment may be configured with multiple TAGs through a transmission/reception point (such as a base station). The user equipment may receive configuration information (for example, TAG configuration information) associated with a plurality of TAGs from a transmission/reception point, and configure (or form) the plurality of TAGs. For example, the TAG configuration information can be transmitted from the transmission/reception point to the user equipment through downlink control information (such as PDCCH) or high layer signaling (such as RRC message).

在步骤S720处，在不同小区中执行SRS和PUSCH/PUCCH的同时传输的情况下，如果总传输功率在不同小区上的传输SRS和PUCCH/PUSCH的符号之间的任何重叠部分上超过用户设备的最大可允许传输功率(P_CMAX)，则用户设备可以放弃与SRS传输相关联的子帧中的SRS。这里，不同小区可以为两个或者更多个不同分量载波。SRS可以为周期SRS和非周期SRS中的一个。At step S720, in the case of performing simultaneous transmission of SRS and PUSCH/PUCCH in different cells, if the total transmission power exceeds the user equipment's The maximum allowable transmission power (P_CMAX ), then the user equipment can give up the SRS in the subframe associated with the SRS transmission. Here, different cells may be two or more different component carriers. The SRS may be one of a periodic SRS and an aperiodic SRS.

换言之，如果在TAG中的、用于给定的服务小区的子帧(例如子帧i)上的符号中的用户设备的SRS传输与在相同TAG或者另一个TAG中的、用于不同服务小区的子帧(例如子帧i或者子帧i+1)上的PUCCH/PUSCH重叠，则如果用户设备的总传输功率在符号的任何重叠部分上超过P_CMAX，则用户设备可以放弃SRS。In other words, if the user equipment's SRS transmission in symbols on a subframe (eg, subframe i) for a given serving cell in a TAG is different from that in the same TAG or in another TAG for a different serving cell PUCCH/PUSCH overlap on a subframe (for example, subframe i or subframe i+1), then if the total transmission power of the user equipment exceeds_PCMAX in any overlapping part of the symbol, the user equipment can give up the SRS.

更具体而言，如图8(a)所示，在(i)不同分量载波(例如CC0和CC1)属于相同TAG(例如TAG0)和(ii)针对不同小区执行SRS和PUSCH/PUCCH的同时传输的情况下，用户设备可以根据是否存在传输功率限制来传输或者放弃SRS。例如，在不存在传输功率限制的情况下，如果形成多个TAG，则用户设备可以传输SRS。在存在传输功率限制的情况下，用户设备可以放弃SRS。同时，如图8(a)和图8(c)所示，在(i)不同分量载波(例如CC0和CC1)属于不同TAG(例如TAG0和TAG1)并且(ii)SRS传输和PUSCH/PUCCH传输完全重叠的情况下，当针对不同小区执行SRS和PUSCH/PUCCH的同时传输时，用户设备可以根据是否存在传输功率限制而传输或者放弃SRS。例如，在不存在传输功率限制的情况下，如果形成多个TAG，则用户设备可以传输SRS。在存在传输功率限制的情况下，用户设备可以放弃SRS。同时，如图8(d)所示，在(i)不同分量载波(例如CC0和CC1)属于不同TAG(例如TAG0和TAG1)并且(ii)SRS传输和PUSCH/PUCCH传输部分重叠的情况下，当针对不同小区执行SRS和PUSCH/PUCCH的同时传输时，用户设备可以根据是否存在传输功率限制而传输或者放弃SRS。例如，在不存在传输功率限制的情况下，如果形成多个TAG，则用户设备可以传输SRS。在存在传输功率限制的情况下，用户设备可以放弃SRS。More specifically, as shown in Figure 8(a), when (i) different component carriers (e.g. CC0 and CC1) belong to the same TAG (e.g. TAG0) and (ii) simultaneous transmission of SRS and PUSCH/PUCCH is performed for different cells In the case of , the user equipment can transmit or give up the SRS according to whether there is a transmission power limitation. For example, in the absence of transmission power limitation, if multiple TAGs are formed, the user equipment can transmit the SRS. In case there is a transmission power limitation, the user equipment may forego SRS. Meanwhile, as shown in Figure 8(a) and Figure 8(c), when (i) different component carriers (such as CC0 and CC1) belong to different TAGs (such as TAG0 and TAG1) and (ii) SRS transmission and PUSCH/PUCCH transmission In the case of complete overlap, when simultaneous transmission of SRS and PUSCH/PUCCH is performed for different cells, the user equipment can transmit or give up SRS according to whether there is a transmission power limitation. For example, in the absence of transmission power limitation, if multiple TAGs are formed, the user equipment can transmit the SRS. In case there is a transmission power limitation, the user equipment may forego SRS. Meanwhile, as shown in FIG. 8(d), in the case that (i) different component carriers (such as CC0 and CC1) belong to different TAGs (such as TAG0 and TAG1) and (ii) SRS transmission and PUSCH/PUCCH transmission partially overlap, When simultaneous transmission of SRS and PUSCH/PUCCH is performed for different cells, the user equipment may transmit or give up SRS according to whether there is a transmission power limitation. For example, in the absence of transmission power limitation, if multiple TAGs are formed, the user equipment can transmit the SRS. In case there is a transmission power limitation, the user equipment may forego SRS.

同时，在用户设备使用三个或者更多个服务小区来配置的情况下，如果在TAG中的、用于给定的服务小区的子帧(例如子帧i)上的符号中的用户设备的SRS传输(i)与用于一个或者多个不同服务小区的子帧(例如子帧i)上的SRS传输重叠，且(ii)与用于一个或者多个另一种小区的子帧(例如子帧i或者子帧i+1)上的PUCCH/PUSCH传输重叠，则如果总传输功率在符号的任何重叠部分上超过P_CMAX，则用户设备可以放弃SRS。换言之，如果用户设备使用三个或者更多个服务小区来配置，则用户设备可以执行在两个或者更多个TAG的三个或者更多个分量载波上的SRS+SRS+PUSCH/PUCCH的同时传输(即SRS、另一个SRS和PUSCH/PUCCH的同时传输)。在这种情况下，如果完全或者部分重叠对应的符号且存在传输功率限制的情况下，则用户设备可以在执行另一个功率比例缩放之前放弃所有的SRS。在这种情况下，如果不存在传输功率限制，则用户设备可以传输所有SRS。Meanwhile, in the case that the user equipment is configured using three or more serving cells, if the symbol of the user equipment on a subframe (for example, subframe i) used for a given serving cell in the TAG SRS transmissions (i) overlap with SRS transmissions on subframes (e.g., subframe i) for one or more different serving cells, and (ii) overlap with subframes for one or more other types of cells (e.g., If the PUCCH/PUSCH transmissions on subframe i or subframe i+1) overlap, the user equipment may drop the SRS if the total transmission power exceeds_PCMAX on any overlapping part of the symbols. In other words, if the user equipment is configured using three or more serving cells, the user equipment can perform simultaneous SRS+SRS+PUSCH/PUCCH on three or more component carriers of two or more TAGs. transmission (ie simultaneous transmission of SRS, another SRS and PUSCH/PUCCH). In this case, the user equipment may discard all SRSs before performing another power scaling if the corresponding symbols overlap completely or partially and there is a transmission power limitation. In this case, if there is no transmission power limitation, the user equipment can transmit all SRSs.

图9是示出根据实施例3的用于在用户设备中控制上行链路功率的方法的流程图。图10是示出根据实施例3的用于在用户设备中控制上行链路功率的概念的示意图。FIG. 9 is a flowchart illustrating a method for controlling uplink power in a user equipment according to Embodiment 3. Referring to FIG. FIG. 10 is a schematic diagram illustrating a concept for controlling uplink power in a user equipment according to Embodiment 3. Referring to FIG.

参照图9，根据实施例3的用于在用户设备中控制上行链路功率的方法(900)可以包括(i)在步骤S910处配置多个TAG并且(ii)在步骤S920处确定SRS传输功率。Referring to FIG. 9, the method (900) for controlling uplink power in a user equipment according to Embodiment 3 may include (i) configuring multiple TAGs at step S910 and (ii) determining SRS transmission power at step S920 .

在步骤S910处，用户设备可以通过传输/接收点(例如基站)被配置有多个TAG。用户设备可以从传输/接收点接收与多个TAG相关联的配置信息(例如，TAG配置信息)，并且配置(或者形成)多个TAG。例如，可以通过下行链路控制信息(例如PDCCH)或者高层信令(例如RRC消息)将TAG配置信息从传输/接收点传输到用户设备。At step S910, the user equipment may be configured with multiple TAGs through a transmission/reception point (such as a base station). The user equipment may receive configuration information (for example, TAG configuration information) associated with a plurality of TAGs from a transmission/reception point, and configure (or form) the plurality of TAGs. For example, the TAG configuration information can be transmitted from the transmission/reception point to the user equipment through downlink control information (such as PDCCH) or high layer signaling (such as RRC message).

在步骤S920处，在存在传输功率限制且执行不同小区上的SRS和另一个SRS(“SRS+SRS”)的同时传输的情况下，用户设备可以通过执行同一功率比例缩放来确定SRS传输功率，其中，比例因子大于0且小于等于1。换言之，如图10(a)所示(在TAG为相同的情况下)、如图10(b)所示(在TAG为不同的且存在部分重叠的情况下)以及如图10(c)所示(在TAG为不同的且存在完全重叠的情况下)，用户设备可以通过执行同一比例缩放来确定SRS传输功率。更具体而言，如果(i)在一个TAG(例如TAG0)中的、用于给定的服务小区的子帧(例如子帧i)上的符号中的用户设备的SRS传输与在不同的TAG(例如TAG1)中的、用于不同服务小区的子帧(例如子帧i)上的SRS传输部分或者完全重叠，并且(ii)存在传输功率限制，则用户设备可以通过执行同一比例缩放来确定用于“SRS+SRS”的同时传输的SRS传输功率，使得总传输功率不超过P_CMAX。在这种情况下，如果不存在传输功率限制，则用户可以在没有执行功率比例缩放的情况下传输SRS。这里，不同小区可以为2个或者多个不同分量载波。SRS可以为周期SRS和非周期SRS中的一个。At step S920, in case there is a transmission power limitation and simultaneous transmission of the SRS and another SRS ("SRS+SRS") on different cells is performed, the user equipment may determine the SRS transmission power by performing the same power scaling, Wherein, the scale factor is greater than 0 and less than or equal to 1. In other words, as shown in Figure 10(a) (in the case of the same TAG), as shown in Figure 10(b) (in the case of different TAGs with partial overlap), and as shown in Figure 10(c) As shown (in case the TAGs are different and there is a complete overlap), the user equipment can determine the SRS transmission power by performing the same scaling. More specifically, if (i) the user equipment's SRS transmission in symbols on a subframe (eg subframe i) for a given serving cell in one TAG (eg TAG0) is different from that in a different TAG SRS transmissions on subframes (e.g. subframe i) for different serving cells in (e.g. TAG1) overlap partially or completely, and (ii) there is a transmission power limitation, then the UE can determine by performing the same scaling SRS transmission power for simultaneous transmission of "SRS+SRS" such that the total transmission power does not exceed_PCMAX . In this case, if there is no transmission power limitation, the user can transmit the SRS without performing power scaling. Here, different cells may be two or more different component carriers. The SRS may be one of a periodic SRS and an aperiodic SRS.

图11是示出根据其它实施例的用于控制上行链路功率的方法的系统流程图。FIG. 11 is a system flow diagram illustrating a method for controlling uplink power according to other embodiments.

参照图1和图11，在步骤S1110处，在多点协作传输/接收(CoMP)或者载波聚合(CA)的情况下，与服务小区对应的第一传输/接收点(例如eNB 110)可以向用户设备120(UE1)传输与多个TAG相关联配置信息(例如TAG配置信息)。这里，可以通过下行链路控制信息(例如PDCCH)或者高层信令(例如RRC消息)将TAG配置信息从第一传输/接收点(例如eNB 110)传输到用户设备120(UE1)。1 and 11, at step S1110, in the case of coordinated multi-point transmission/reception (CoMP) or carrier aggregation (CA), the first transmission/reception point corresponding to the serving cell (e.g. eNB 110) may send The user equipment 120 (UE1) transmits configuration information associated with multiple TAGs (eg TAG configuration information). Here, the TAG configuration information may be transmitted from the first transmission/reception point (eg eNB 110) to the user equipment 120 (UE1) through downlink control information (eg PDCCH) or high layer signaling (eg RRC message).

在步骤S1120处，用户设备120(UE1)可以接收TAG配置信息，并且配置(或者形成)多个TAG。如上所述，尽管用户设备通过传输/接收点而被配置有多个TAG，但是在载波聚合(CA)情况下的特定分量载波可以属于相同TAG。例如，在配置两个上行链路分量载波的情况下，每个分量载波可以属于相同TAG。对于另一个示例而言，在配置三个上行链路分量载波的情况下，两个上行链路分量载波可以属于相同TAG，而其它上行链路分量载波可以属于另一个TAG(即不同的TAG)。At step S1120, the user equipment 120 (UE1) may receive TAG configuration information, and configure (or form) multiple TAGs. As described above, although a user equipment is configured with a plurality of TAGs by a transmission/reception point, a specific component carrier in case of carrier aggregation (CA) may belong to the same TAG. For example, in the case of configuring two uplink component carriers, each component carrier may belong to the same TAG. For another example, where three uplink component carriers are configured, two uplink component carriers may belong to the same TAG, while other uplink component carriers may belong to another TAG (ie different TAG) .

在步骤S1130处，用户设备120(UE1)可以根据上述的情况1到情况4来执行资源映射和与上行链路信道(例如上行链路数据信道和/或上行链路控制信道)和SRS相关联的功率控制。这里，“情况1”表示(i)不同分量载波属于相同TAG，或者属于不同TAG的不同分量载波完全重叠,(ii)期望PUCCH/PUSCH和SRS的同时传输，以及(iii)存在传输功率限制的情况。“情况2”表示(i)不同分量载波属于相同TAG，或者属于不同TAG的不同分量载波完全重叠，(ii)期望PUCCH/PUSCH和SRS的同时传输，以及(iii)不存在传输功率受限的情况。“情况3”表示(i)属于不同TAG的不同分量载波不完全重叠(即部分地重叠)，(ii)期望PUCCH/PUSCH和SRS的同时传输，以及(iii)存在传输功率限制的情况。“情况4”表示(i)属于不同TAG的不同分量载波不完全重叠(即部分地重叠)，(ii)期望PUCCH/PUSCH和SRS的同时传输，以及(iii)不存在传输功率限制的情况。At step S1130, the user equipment 120 (UE1) may perform resource mapping and association with uplink channels (eg, uplink data channels and/or uplink control channels) and SRSs according to the above-mentioned cases 1 to 4 power control. Here, "Case 1" means that (i) different component carriers belong to the same TAG, or different component carriers belonging to different TAGs completely overlap, (ii) simultaneous transmission of PUCCH/PUSCH and SRS is expected, and (iii) there is a transmission power limitation Condition. "Case 2" means (i) different component carriers belong to the same TAG, or different component carriers belonging to different TAGs completely overlap, (ii) simultaneous transmission of PUCCH/PUSCH and SRS is expected, and (iii) there is no transmission power limited Condition. "Case 3" represents a case where (i) different component carriers belonging to different TAGs do not completely overlap (ie partially overlap), (ii) simultaneous transmission of PUCCH/PUSCH and SRS is desired, and (iii) there is a transmission power limitation. "Case 4" represents a case where (i) different component carriers belonging to different TAGs do not completely overlap (ie partially overlap), (ii) simultaneous transmission of PUCCH/PUSCH and SRS is desired, and (iii) there is no transmission power limitation.

在步骤S1130处，例如，如参照图5和图6所述，在SRS和PUSCH在相同小区上的同时传输的情况下，用户设备可以执行上行链路资源映射，使得用于PUSCH的资源单元被映射到除了为子帧中的SRS传输分配的最后符号之外的SC-FDMA符号。由于参照上面的实施例1详细描述了这种操作，所以省略了其详细描述。At step S1130, for example, as described with reference to FIG. 5 and FIG. 6, in case of simultaneous transmission of SRS and PUSCH on the same cell, the user equipment may perform uplink resource mapping such that resource elements for PUSCH are Mapped to SC-FDMA symbols other than the last symbol allocated for SRS transmission in a subframe. Since this operation was described in detail with reference to Embodiment 1 above, its detailed description is omitted.

在步骤S1130处，针对另一个示例，如参照图7和图8所述，在不同小区中执行SRS和PUSCH/PUCCH的同时传输的情况下，如果总传输功率在不同小区上的传输SRS和PUCCH/PUSCH的符号之间的任何重叠部分上超过用户设备的最大可允许传输功率(P_CMAX)，则用户设备可以放弃与SRS传输相关联的子帧中的SRS。由于如实施例2已经详细描述了这种操作，所以省略了其详细描述。At step S1130, for another example, as described with reference to FIG. 7 and FIG. 8, in the case of performing simultaneous transmission of SRS and PUSCH/PUCCH in different cells, if the total transmission power of the transmission of SRS and PUCCH on different cells If any overlap between the symbols of PUSCH exceeds the maximum allowable transmission power (P_CMAX ) of the user equipment, the user equipment may give up the SRS in the subframe associated with the SRS transmission. Since this operation has already been described in detail as in Embodiment 2, its detailed description is omitted.

在步骤S1130处，针对另一个实施例，如参照图9和图10所述，在存在传输功率限制且执行SRS和另一个SRS(“SRS+SRS”)在不同小区上的同时传输的情况下，用户设备120可以通过执行同一功率比例缩放来确定SRS传输功率。由于参照上面的实施例3详细描述了这种操作，所以省略了其详细描述。At step S1130, for another embodiment, as described with reference to FIG. 9 and FIG. 10 , in case there is transmission power restriction and simultaneous transmission of SRS and another SRS ("SRS+SRS") on different cells is performed , the user equipment 120 may determine the SRS transmission power by performing the same power scaling. Since this operation was described in detail with reference to Embodiment 3 above, its detailed description is omitted.

而且，在两个或者更多个不同分量载波被配置为用于用户设备的上行链路传输且用户设备被配置有多个TAG的情况下，用户设备的操作可以根据用户设备是处于功率受限情形还是非功率受限情形来限定。具体地，与(i)不同分量载波(CC)属于相同TAG或者(ii)属于不同TAG的不同分量载波完全重叠的情况相关联的UE操作方法可以首先被施加。此后，与属于不同TAG的不同分量载波未完全重叠(即部分重叠)的情况相关联的UE操作还可以被进一步地施加。Also, in case two or more different component carriers are configured for uplink transmission of the user equipment and the user equipment is configured with multiple TAGs, the operation of the user equipment may be based on whether the user equipment is in power limited The situation is also defined as a non-power-limited situation. Specifically, a UE operation method associated with a case where (i) different component carriers (CCs) belong to the same TAG or (ii) different component carriers belonging to different TAGs completely overlap may be applied first. Thereafter, UE operations associated with the case where different component carriers belonging to different TAGs do not fully overlap (ie partially overlap) may be further applied.

换言之，针对属于相同TAG的不同分量载波的UE操作可以首先被定义为使得可以施加向后兼容性。因此，当在相同TAG下传输上行链路信道(例如上行链路控制信道和/或上行链路数据信道)和SRS时，可以执行针对特定信道和/或信号的功率控制或者放弃程序。而且，可以最大地保证通过属于不同TAG的分量载波的上行链路数据信道传输和SRS传输。In other words, UE operations for different component carriers belonging to the same TAG can first be defined such that backward compatibility can be applied. Therefore, when an uplink channel (eg, an uplink control channel and/or an uplink data channel) and an SRS are transmitted under the same TAG, a power control or drop procedure for a specific channel and/or signal may be performed. Also, uplink data channel transmission and SRS transmission through component carriers belonging to different TAGs can be guaranteed maximally.

此外，根据针对用户设备定义的这种操作，在载波聚合的情况下，可以通过避免上行链路数据信道的过多功率控制来阻止数据信道中的数据传输速率的降低。而且，针对SRS，可以阻止根据特定条件的满足的频繁下降和/或过多功率控制，由此保证在载波聚合的情况下的SRS传输的可靠性。因此，可以获得根据频率依赖的调度的增益和/或根据时分复用(TDD)中的信道互易性的波束形成增益。Furthermore, according to such an operation defined for the user equipment, in case of carrier aggregation, it is possible to prevent the reduction of the data transmission rate in the data channel by avoiding excessive power control of the uplink data channel. Also, for SRS, frequent drops and/or excessive power control according to satisfaction of certain conditions can be prevented, thereby ensuring reliability of SRS transmission in case of carrier aggregation. Accordingly, a gain according to frequency-dependent scheduling and/or a beamforming gain according to channel reciprocity in time division duplexing (TDD) can be obtained.

如实施例1所述，控制处理器1320可以形成多个TAG且执行用于SRS和PUSCH在相同小区上的同时传输的资源映射。这里，资源映射可以被执行为使得传输PUSCH的子帧的最后符号未被映射到用于PUSCH的资源单元。可替换地，如实施例2所述，控制处理器1320可以形成多个TAG，并且在SRS和PUSCH/PUCCH(即PUSCH和/或PUCCH)在不同小区上的同时传输的情况下控制SRS传输。这里，控制可以包括：如果总传输功率在不同小区上传输SRS和PUCCH/PUSCH的符号之间的任何重叠部分上超过用户设备1300的最大可允许传输功率(P_CMAX)则放弃SRS。可替换地，如实施例3所述，在SRS(这里称为“第一SRS”)和另一个SRS(这里称为“第二SRS”)在不同小区上同时传输的情况下(即在SRS+SRS的同时传输的情况下)，控制处理器1320可以通过执行同一比例缩放来确定传输给不同小区中的每一个的每个SRS的传输功率，如果总传输功率在传输第一SRS和第二SRS的符号之间的重叠部分上超过用户设备1300的最大可允许传输功率的话。As described in Embodiment 1, the control processor 1320 may form multiple TAGs and perform resource mapping for simultaneous transmission of SRS and PUSCH on the same cell. Here, resource mapping may be performed such that the last symbol of a subframe in which PUSCH is transmitted is not mapped to resource elements for PUSCH.

发射机1330可以通过对应的信道向传输/接收点传输控制信息、数据和/或消息。The transmitter 1330 may transmit control information, data and/or messages to a transmission/reception point through a corresponding channel.

在上述实施例的情况下，在用户设备在载波聚合的情况下被配置有多个TAG且在不同分量载波上传输一个或者多个上行链路控制/数据信道和SRS的情况下，用户设备的操作可以根据是否存在用于用户设备的传输功率限制而被定义。因此，可以克服根据传输/接收点的请求的用户设备的不定性关联的上行链路信道/信号传输。In the case of the above-mentioned embodiments, when the user equipment is configured with multiple TAGs in the case of carrier aggregation and transmits one or more uplink control/data channels and SRS on different component carriers, the user equipment's Operation may be defined according to whether there is a transmission power limitation for the user equipment.
