本发明涉及通信领域技术，特别涉及一种CoMP场景下确定上行控制信道基序列和物理资源的方法及其装置。The present invention relates to the technology in the communication field, in particular to a method and a device for determining an uplink control channel base sequence and physical resources in a CoMP scenario.
背景技术Background technique
在增强的长期演进(LTE-A，Long Term Evolution Advanced)系统中，协作多点(CoMP，Coordinated Multi-point)传输/接收作为关键技术之一被纳入到LTE-A系统中。协作传输场景利用地理位置相邻的传输点协作发送信号给用户设备，对于小区边缘用户，尤其能改善信号质量，扩大覆盖范围。在3GPP LTE-A标准化过程中，对于上下行CoMP(UL/DLCoMP)定义了以下四种场景：In an enhanced Long Term Evolution (LTE-A, Long Term Evolution Advanced) system, Coordinated Multi-point (CoMP, Coordinated Multi-point) transmission/reception is incorporated into the LTE-A system as one of key technologies. In the cooperative transmission scenario, transmission points adjacent to each other are used to cooperatively send signals to user equipment. For cell edge users, signal quality can be improved and coverage can be expanded. During the 3GPP LTE-A standardization process, the following four scenarios are defined for uplink and downlink CoMP (UL/DLCoMP):
场景1：同构网络的站址间CoMP(Homogenous Network with Intra-site CoMP)；Scenario 1: Homogenous Network with Intra-site CoMP (Homogenous Network with Intra-site CoMP);
场景2：具有高发送功率远端无线单元(RRH，Remote Radio Head)的同构网络；Scenario 2: Homogeneous network with high transmit power Remote Radio Head (RRH, Remote Radio Head);
场景3：宏小区范围分布低功率RRH的具有不同小区标识(Cell ID)的异构网络场景；Scenario 3: A heterogeneous network scenario with different cell IDs (Cell ID) in which low-power RRHs are distributed in a macro cell;
场景4：宏小区范围分布低功率RRH的具有相同小区ID的异构网络场景。Scenario 4: A heterogeneous network scenario with the same cell ID in which low-power RRHs are distributed in a macro cell range.
上行控制信道(PUCCH，Physical Uplink Control Channel)用来承载对下行数据信道(PDSCH)的正确/错误(ACK/NACK)接收反馈，例如PUCCH format 1/1a/1b。另外，PUCCH也可以用来承载下行信道的信道状态信息(CSI)，例如PUCCH format 2/2a/2b。在Rel.10中，上行控制信道PUCCH由恒包络零自相关(CAZAC，Constant Amplitude Zero AutoCorrelation)序列(sequence)作为基序列，其基序列分成30个序列组，序列组标号由u表示，u∈{0，1，2，......，29}；每个序列组中包含一个或两个基序列，v表示一个序列组中基序列的标号，v＝0，1。一个用户的PUCCH基序列由序列组标号u和一个序列组中基序列标号v共同决定。相同小区的所有用户采用相同的序列组，不同小区的用户采用不同的序列组。由于一个小区的不同用户采用相同的序列组标号，所以当两个用户占用相同的上行物理块资源(PRB)发送PUCCH时，可以通过不同的循环移位(CS，Cyclic Shift)和/或不同的正交掩码(OCC，Orthogonal Cover Code)来保证小区内的PUCCH正交性，从而保证较低的小区间干扰。同时，多个用户可占用相同的CS和/或OCC但占用不同的PRB，以保证其正交性。An uplink control channel (PUCCH, Physical Uplink Control Channel) is used to carry correct/error (ACK/NACK) reception feedback on a downlink data channel (PDSCH), such as PUCCH format 1/1a/1b. In addition, the PUCCH can also be used to carry channel state information (CSI) of the downlink channel, such as PUCCH format 2/2a/2b. In Rel.10, the uplink control channel PUCCH has a constant envelope zero autocorrelation (CAZAC, Constant Amplitude Zero AutoCorrelation) sequence (sequence) as the base sequence, and its base sequence is divided into 30 sequence groups, and the sequence group label is represented by u, u ∈{0,1,2,...,29}; each sequence group contains one or two base sequences, v represents the label of the base sequence in a sequence group, v=0,1. A user's PUCCH base sequence is jointly determined by the sequence group index u and the base sequence index v in a sequence group. All users in the same cell use the same sequence group, and users in different cells use different sequence groups. Since different users of a cell use the same sequence group number, when two users occupy the same uplink physical block resource (PRB) to send PUCCH, they can use different cyclic shifts (CS, Cyclic Shift) and/or different Orthogonal Cover Code (OCC, Orthogonal Cover Code) is used to ensure the orthogonality of the PUCCH in the cell, so as to ensure low inter-cell interference. Meanwhile, multiple users may occupy the same CS and/or OCC but different PRBs to ensure their orthogonality.
PUCCH所占用的物理资源对应CS，OCC及PRB的组合。对于动态的物理下行共享信道(PDSCH，Physical Downlink Share Channel)传输，PUCCH format 1/1a/1b的物理资源由调度PDSCH的物理下行控制信道(PDCCH，Physical Downlink ControlChannel)的控制信道元素(CCE，Control Channel Element)索引(index)动态决定，其中nCCE为PDCCH的CCE的起始序号，为小区公共参数，由高层信令配置。Physical resources occupied by PUCCH Corresponding to the combination of CS, OCC and PRB. For dynamic physical downlink shared channel (PDSCH, Physical Downlink Share Channel) transmission, the physical resources of PUCCH format 1/1a/1b It is dynamically determined by the control channel element (CCE, Control Channel Element) index (index) of the physical downlink control channel (PDCCH, Physical Downlink ControlChannel) scheduling PDSCH, where nCCE is the starting sequence number of the CCE of the PDCCH, It is a public parameter of the cell and is configured by high-layer signaling.
在实现本发明的过程中发明人发现，在Release 11的上行CoMP场景中，上述PUCCH的设计并不能很好工作，目前还没有有效的解决方法。以下举例说明。In the process of realizing the present invention, the inventors found that in the uplink CoMP scenario of Release 11, the above-mentioned PUCCH design does not work well, and there is no effective solution at present. The following example illustrates.
图1是CoMP场景3的网络架构示意图。如图1所示，CoMP UE1的下行物理控制信道由eNB调度，但是其PUCCH是宏基站(Macro eNB)和RRH1共同接收。如果沿用R10的PUCCH设计方法，当该RRH1内同时存在UE2占用与该CoMP UE1相同的PRB发送PUCCH时，该CoMP UE1和UE2会采用不同的CAZAC序列组，由于不同的CAZAC序列的互相关系数非零，该UE2的PUCCH与CoMP UE1的PUCCH互相干扰。FIG. 1 is a schematic diagram of a network architecture of CoMP scenario 3. As shown in FIG. 1 , the downlink physical control channel of CoMP UE1 is scheduled by eNB, but its PUCCH is jointly received by the macro base station (Macro eNB) and RRH1. If the PUCCH design method of R10 is followed, when UE2 occupies the same PRB as the CoMP UE1 to send PUCCH in the RRH1, the CoMP UE1 and UE2 will use different CAZAC sequence groups, because the cross-correlation coefficients of different CAZAC sequences are not 0, the PUCCH of the UE2 interferes with the PUCCH of the CoMP UE1.
此外，在CoMP场景4下，RRH和eNB共享一个小区ID，若沿用现有的PUCCH设计，所有用户的PUCCH相同的序列组，理论上小区内的各个用户能够达到理想正交。然而在CoMP场景4下，不同RRH采用完全相同的序列组，不能实现小区分裂增益(Cell Splitting Gain)；另一方面，由于RRH的引入，同时服务的用户数量增多，当前设计的PUCCH不能提供足够的正交资源如CS、OCC及PRB，从而会存在大量的RRH之间干扰，即inter-point干扰。因此在CoMP场景4下，需要考虑inter-point的干扰随机化增强技术。In addition, in CoMP scenario 4, RRH and eNB share a cell ID. If the existing PUCCH design is used, the PUCCH sequence group of all users is the same. In theory, each user in the cell can achieve ideal orthogonality. However, in CoMP scenario 4, different RRHs use exactly the same sequence group, which cannot achieve Cell Splitting Gain; Orthogonal resources such as CS, OCC and PRB, so there will be a lot of interference between RRHs, that is, inter-point interference. Therefore, in CoMP scenario 4, inter-point interference randomization enhancement technology needs to be considered.

具体实施方式Detailed ways
下面结合附图对本发明的各种实施方式进行说明。这些实施方式只是示例性的，不是对本发明的限制。为了使本领域的技术人员能够容易地理解本发明的原理和实施方式，本发明的实施方式以用于PUCCH format 1/1a/1b，也用于PUCCH format 2/2a/2b的确定CoMP传输系统的上行控制信道的基序列和物理资源的方法为例进行说明，但可以理解，本发明并不限于上述系统和PUCCH传输，对于涉及确定上行控制信道的基序列和物理资源的其他系统均适用。Various embodiments of the present invention will be described below in conjunction with the accompanying drawings. These embodiments are illustrative only, and do not limit the present invention. In order to enable those skilled in the art to easily understand the principle and implementation of the present invention, the implementation of the present invention is used for PUCCH format 1/1a/1b, and is also used for PUCCH format 2/2a/2b to determine the CoMP transmission system The method of the base sequence and physical resources of the uplink control channel is described as an example, but it can be understood that the present invention is not limited to the above-mentioned system and PUCCH transmission, and is applicable to other systems involving determining the base sequence and physical resources of the uplink control channel.
为了解决背景技术中所述的各场景下存在的问题，发明人在研究中发现使用何种基序列是由当前的上行CoMP模式决定，例如是单点接收还是多点接收，接收点是与下行发送点相同还是不同。另一方面，使用何种基序列也与CoMP的优化目标有关，以避免干扰为目标或是干扰随机化为目标。并且为支持灵活的调度以获得更大的CoMP增益，基序列需动态变化，进而使得PUCCH的物理资源需动态变化，以避免干扰。因此，本发明实施例提供一种可动态选择PUCCH的基序列和物理资源的方法，以避免干扰或达到干扰随机化的效果，同时可提高PUCCH的利用效率。以下结合附图对本发明实施例进行详细说明。In order to solve the problems existing in various scenarios described in the background technology, the inventor found in the research which base sequence to use is determined by the current uplink CoMP mode, such as single-point reception or multi-point reception, and whether the receiving point is connected to the downlink Whether the sending point is the same or different. On the other hand, which base sequence to use is also related to the optimization goal of CoMP, to avoid interference or to randomize interference. And in order to support flexible scheduling to obtain greater CoMP gain, the base sequence needs to be changed dynamically, so that the physical resources of the PUCCH need to be changed dynamically to avoid interference. Therefore, the embodiment of the present invention provides a method for dynamically selecting the base sequence and physical resources of the PUCCH, so as to avoid interference or achieve the effect of interference randomization, and at the same time improve the utilization efficiency of the PUCCH. Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

并且在为需要下行ACK/NACK反馈和信道状态信息反馈的上行控制信道传输配置相关参数时，配置的该相关参数中的用户专用的虚拟小区标识可相同，并且配置的物理资源指示索引各自独立且一一对应，这样可简化信令。And when configuring related parameters for uplink control channel transmission that requires downlink ACK/NACK feedback and channel state information feedback, the user-specific virtual cell identifier in the configured related parameters may be the same, and the configured physical resource indication indexes are independent and correspond one-to-one, which can simplify signaling.

步骤407，该用户设备根据该参数确定基序列和物理资源；Step 407, the user equipment determines a base sequence and a physical resource according to the parameter;
在本实施例中，例如，该PUCCH基序列为CAZAC序列，如果网络侧为其选择一组用户专用的参数可按照以下方式确定基序列：In this embodiment, for example, the PUCCH base sequence is a CAZAC sequence, if the network side selects a set of user-specific parameters for it The base sequence can be determined as follows:
1)利用公式(2)和(3)计算伪随机序列c的初始化状态和序列移位图样该公式(2)和(3)分别为：1) Use formulas (2) and (3) to calculate the initialization state and sequence shift pattern of the pseudo-random sequence c The formulas (2) and (3) are respectively:
2)通过公式(4)产生PUCCH序列该公式(4)为：2) Generate PUCCH sequence by formula (4) The formula (4) is:
在公式(4)中，In formula (4),
为预先设定的序列，如TS 36.211中Table 5.5.1.2-1&Table 5.5.1.2-2； It is a preset sequence, such as Table 5.5.1.2-1&Table 5.5.1.2-2 in TS 36.211;
α表示循环位移(CS)，由等元素决定；α represents the cyclic shift (CS), given by determined by other elements;
n表示该序列的第n个元素；n represents the nth element of the sequence;
u表示序列组标号，u∈{0，1，2，......，29}，每个序列组中包含一个或两个基序列；u represents the sequence group label, u ∈ {0, 1, 2, ..., 29}, each sequence group contains one or two base sequences;
v表示一个序列组中基序列的标号，v＝0，1；v represents the label of the base sequence in a sequence group, v=0,1;
对于一个用户设备来说，一个TTI内发送的PUCCH只占用一个资源块(ResourceBlock，RB)，其基序列BS仅跟序列组标号u有关，与基序列标号v无关，v＝0。在时隙ns中，序列组标号u是由序列组跳变图样(Group Hopping Pattern)和序列移位图样(SequenceShift Pattern)共同决定。即序列组标号u可采用公式(5)和(6)获得：For a user equipment, the PUCCH sent in one TTI only occupies one resource block (ResourceBlock, RB), and its base sequence BS is only related to the sequence group label u, and has nothing to do with the base sequence label v, v=0. In the time slot ns , the sequence group label u is jointly determined by the sequence group hopping pattern (Group Hopping Pattern) and the sequence shift pattern (SequenceShift Pattern). That is, the sequence group label u can be obtained using formulas (5) and (6):
u＝(fgh(ns)+fss)mod30， (5)u=(fgh (ns )+fss ) mod 30, (5)
在公式(5)和(6)中：In formulas (5) and (6):
fgh表示序列组跳变图样，ns表示时隙标号，范围是[0～19]；fgh represents the sequence group hopping pattern, ns represents the time slot label, and the range is [0～19];
fss表示序列移位图样，由公式(2)计算，c(y)＝c(8ns+i)是伪随机序列。fss represents a sequence shift pattern, calculated by formula (2), c(y)=c(8ns +i) is a pseudo-random sequence.
由上述可知，可利用公式(2)～(6)获得PUCCH的基序列。It can be known from the above that the base sequence of PUCCH can be obtained by using formulas (2)-(6).
在本实施例中，通过来确定该物理资源，即CS，OCC和PRB资源，例如PRB序号由公式(7)获得：In this example, by To determine the physical resources, namely CS, OCC and PRB resources, for example, the PRB sequence number is obtained by formula (7):
PUCCH映射的PRB索引m可表示为：The PRB index m of PUCCH mapping can be expressed as:
其中，为PUCCH format 2/2a/2b所占用RB数，为混合的PRB内format 1/1a/1b占用的CS数。为format 1/1a/1b可用CS的最小间隔，in, The number of RBs occupied by PUCCH format 2/2a/2b, It is the number of CSs occupied by format 1/1a/1b in the mixed PRB. The minimum interval of available CS for format 1/1a/1b,
在本实施例中，如果网络侧选择的参数是小区共有参数，即方法与上述类似，只是在确定PUCCH基序列时，将上述公式中的替换为In this embodiment, if the parameter selected by the network side is a parameter shared by the cell, that is, The method is similar to the above, except that when determining the PUCCH base sequence, the above formula replace with
在本实施例中，如果网络侧选择的参数是小区共有参数，即在根据该参数确定PUCCH基序列时，方法与上述类似，将上述公式中的替换为在确定物理资源时，需要根据下面公式(7)首先确定物理资源指示索引，然后再利用该物理资源指示索引来确定物理资源。公式(7)如下：In this embodiment, if the parameter selected by the network side is a parameter shared by the cell, that is, When determining the PUCCH base sequence according to this parameter, the method is similar to the above, and the above formula replace with When determining the physical resource, it is necessary to first determine the physical resource indication index according to the following formula (7), and then use the physical resource indication index to determine the physical resource. Formula (7) is as follows:
由上述实施例可知，网络侧为用户设备配置相关参数，其中直接配置用户专用PUCCH物理资源指示索引并动态选择一组参数用来确定PUCCH基序列和物理资源，可避免干扰或达到干扰随机化的目的，提高PUCCH的利用效率。此外，对于上述步骤的执行顺序可根据实际情况进行调整，如步骤403可与步骤404互换，也可与步骤406并列执行等。It can be seen from the above embodiments that the network side configures relevant parameters for the user equipment, where the user-specific PUCCH physical resource indication index is directly configured And dynamically select a set of parameters to determine the PUCCH base sequence and physical resources, which can avoid interference or achieve the purpose of interference randomization, and improve the utilization efficiency of PUCCH. In addition, the execution sequence of the above steps can be adjusted according to the actual situation, for example, step 403 can be interchanged with step 404, and can also be executed in parallel with step 406, etc.
本发明实施例4还提供一种确定上行控制信道的基序列和物理资源的方法。在本实施例中，对于与实施例3类似的步骤流程不进行说明，仅对不同之处进行说明。Embodiment 4 of the present invention also provides a method for determining the base sequence and physical resource of the uplink control channel. In this embodiment, the steps similar to those in Embodiment 3 will not be described, and only the differences will be described.
其中，与实施例3的不同之处在于：Wherein, the difference with embodiment 3 is:
在步骤401中，所配置的用户专用的参数中，不直接配置用户专用物理资源指示索引而是配置用于确定该的参数，例如该参数为In step 401, among the configured user-specific parameters, the user-specific physical resource indication index is not directly configured Instead the configuration is used to determine the parameters, for example, the parameter is
在步骤404中，网络侧如果选择用户专用的参数时，该用户专用的参数可表示为In step 404, if the network side selects user-specific parameters, the user-specific parameters can be expressed as
在步骤407中，在利用该确定时，可利用公式(8)：In step 407, using the Sure , formula (8) can be used:
由上述实施例可知，网络侧为用户设备配置相关参数，其中不直接配置用户专用PUCCH物理资源指示索引而是配置确定该的参数，并动态选择一组参数用来确定PUCCH基序列和物理资源，可避免干扰或达到干扰随机化的目的，提高PUCCH的利用效率。It can be seen from the above embodiments that the network side configures relevant parameters for the user equipment, and does not directly configure the user-specific PUCCH physical resource indication index Instead the configuration determines the parameters, and dynamically select a group of parameters to determine the PUCCH base sequence and physical resources, which can avoid interference or achieve the purpose of interference randomization, and improve the utilization efficiency of PUCCH.
图5是本发明实施例5的确定上行控制信道的基序列和物理资源的方法流程图。在本实施例中，以网络侧配置相关参数为例进行说明。与实施例3和4的不同之处在于对用户专用的参数的配置，网络侧仅配置用户专用的物理资源指示索引FIG. 5 is a flowchart of a method for determining base sequences and physical resources of an uplink control channel according to Embodiment 5 of the present invention. In this embodiment, configuration of related parameters on the network side is taken as an example for description. The difference from Embodiments 3 and 4 lies in the configuration of user-specific parameters, and the network side only configures user-specific physical resource indication indexes
如图5所示，该方法包括：As shown in Figure 5, the method includes:
步骤501，网络侧配置相关参数，该相关参数包括小区共有的参数和用户专用的参数；Step 501, the network side configures related parameters, and the related parameters include cell-common parameters and user-specific parameters;
在本实施例中，网络侧的用户设备所属服务小区的基站根据小区或发送点的分布及负载情况，用户设备可能的发送或接收方式等，为每个用户配置用户专用的参数；此外，还配置小区共有的参数；In this embodiment, the base station of the serving cell to which the user equipment belongs on the network side configures user-specific parameters for each user according to the distribution and load of the cells or transmission points, the possible transmission or reception modes of the user equipment, etc.; Configure the parameters shared by the cell;
其中，小区共有的小区专用(Cell-Speicific)参数如实施例3和4所述，此处不再赘述；Wherein, the cell-specific (Cell-Speicific) parameters shared by the cell are as described in embodiments 3 and 4, and will not be repeated here;
该用户专用的参数与实施例3和4不同，仅配置与用户专用的虚拟小区标识对应的小区专用的物理资源指示索引在这种情况下，该用户专用的虚拟小区标识与其他导频符号绑定，这样，可节省信令开销；The user-specific parameters are different from Embodiments 3 and 4, only the cell-specific physical resource indication index corresponding to the user-specific virtual cell identifier is configured In this case, the user-specific virtual cell identity Binding with other pilot symbols, thus saving signaling overhead;
例如，该导频符号为PUSCH的DM-RS或UL CoMP接收点配置的CSI-RS，如果该基站为该PUSCH的DM-RS或CSI-RS配置了一组或多组UE-specific虚拟小区标识，如则该确定PUCCH基序列所使用的UE-specific虚拟小区标识与PUSCH的DM-RS或CSI-RS的虚拟小区标识一致，并且该基站为该UE配置的与该一一对应。For example, the pilot symbol is the DM-RS of PUSCH or the CSI-RS configured by the UL CoMP receiving point, if the base station configures one or more sets of UE-specific virtual cell identities for the DM-RS or CSI-RS of the PUSCH ,like Then determine the UE-specific virtual cell identity used by the PUCCH base sequence Virtual cell identity with DM-RS or CSI-RS of PUSCH Consistent, and the base station configured for the UE with the One to one correspondence.
步骤502，将配置的相关参数通知用户设备；Step 502, notifying the user equipment of the configured relevant parameters;
在本实施例中，该基站可通过高层信令通知该相关参数。In this embodiment, the base station may notify the relevant parameters through high-layer signaling.
步骤503，该用户设备接收网络侧为其配置的该相关参数。Step 503, the user equipment receives the relevant parameters configured for it by the network side.
步骤504，网络侧从配置的该相关参数中选择一组确定PUCCH基序列和物理资源的参数；Step 504, the network side selects a set of parameters for determining the PUCCH base sequence and physical resources from the configured relevant parameters;
在本实施例中，网络侧根据该用户设备的实际调度情况和不同目的从该相关参数中动态地选择用于确定上行控制信道传输的基序列和物理资源的参数；In this embodiment, the network side dynamically selects the parameters used to determine the base sequence and physical resources for uplink control channel transmission from the relevant parameters according to the actual scheduling situation and different purposes of the user equipment;
其中，选择的参数可以为小区共有的参数，如或也可以为一组用户专用的参数Wherein, the selected parameter may be a parameter shared by the cell, such as or Can also be a set of user-specific parameters
在本实施例中，在选择用户专用的参数时，可根据上述导频符号所使用的虚拟小区标识来选择例如，若PUSCH DM-RS或CSI-RS采用作为UE-specific虚拟小区标识，则选择该作为UE-specific虚拟小区标识且选择与其对应的In this embodiment, when selecting user-specific parameters, it can be selected according to the virtual cell identity used by the above-mentioned pilot symbols For example, if PUSCH DM-RS or CSI-RS uses As a UE-specific virtual cell identifier, select the As a UE-specific virtual cell identifier and select the corresponding
步骤505，该基站将选择的参数通知该用户设备；Step 505, the base station notifies the user equipment of the selected parameters;
在本实施例中，该基站通过物理层或MAC层信令通知该用户设备，其中可通过DCI来通知；In this embodiment, the base station notifies the user equipment through physical layer or MAC layer signaling, which may be notified through DCI;
例如，在与PUSCH的DM-RS绑定时，由于网络侧需要动态选择一组PUSCH DMRS的参数，因此，可以用指示PUSCH DMRS参数的DCI同时指示PUCCH的参数。即DCI中的1个或2个比特指示PUCCH与DMRS的参数。For example, when binding with the DM-RS of the PUSCH, since the network side needs to dynamically select a set of PUSCH DMRS parameters, the DCI indicating the PUSCH DMRS parameters can be used to indicate the PUCCH parameters at the same time. That is, 1 or 2 bits in the DCI indicate the parameters of the PUCCH and DMRS.
例如，在与CSI-RS绑定而未与DM-RS绑定时，由于CSI-RS不需要动态选择一组参数，因此，还需要有1or 2bits指示用于PUCCH的与其中为第i套CSI-RS的虚拟小区标识For example, when binding with CSI-RS but not binding with DM-RS, since CSI-RS does not need to dynamically select a set of parameters, therefore, 1 or 2 bits are required to indicate the parameters used for PUCCH and in is the virtual cell identifier of the i-th set of CSI-RS
步骤506，该用户设备接收网络侧为其选择的参数。Step 506, the user equipment receives the parameters selected for it by the network side.
步骤507，该用户设备根据该参数确定基序列和物理资源；Step 507, the user equipment determines a base sequence and a physical resource according to the parameter;
在本实施例中，确定基序列和物理资源的方式与实施例3类似，此处不再赘述。In this embodiment, the manner of determining the base sequence and the physical resource is similar to that of Embodiment 3, and will not be repeated here.
由上述实施例可知，网络侧为用户设备配置相关参数，其中只配置用户专用PUCCH物理资源指示索引而与导频符号的绑定，这样可简化信令；并动态选择一组参数用来确定PUCCH基序列和物理资源，可避免干扰或达到干扰随机化的目的，提高PUCCH的利用效率。此外，对于上述步骤的执行顺序可根据实际情况进行调整，与实施例3和4类似，此处不再赘述。It can be seen from the above embodiments that the network side configures relevant parameters for the user equipment, where only the user-specific PUCCH physical resource indication index is configured and with pilot symbols Binding, which can simplify signaling; and dynamically select a set of parameters to determine the PUCCH base sequence and physical resources, which can avoid interference or achieve the purpose of interference randomization, and improve the utilization efficiency of PUCCH. In addition, the execution order of the above steps can be adjusted according to the actual situation, which is similar to that of Embodiments 3 and 4, and will not be repeated here.
本发明实施例6还提供一种确定上行控制信道的基序列和物理资源的方法。在本实施例中，对于与实施例5类似的步骤流程不进行说明，仅对不同之处进行说明。Embodiment 6 of the present invention also provides a method for determining the base sequence and physical resource of the uplink control channel. In this embodiment, the steps similar to those in Embodiment 5 will not be described, and only the differences will be described.

实例3：Example 3:
图14是本发明实施例17的场景示意图。以下结合附图14所示的场景对参数的配置进行说明，对于参数的选择与上述实施例类似。Fig. 14 is a schematic diagram of a scene according to Embodiment 17 of the present invention. The configuration of parameters will be described below in conjunction with the scene shown in FIG. 14 , and the selection of parameters is similar to the above-mentioned embodiment.
如图14所示，对于低版本的传统用户(Legacy UE)，仅有一组小区共有(cell-specifc)的参数(和)。As shown in Figure 14, for legacy users (Legacy UE) of a lower version, there is only one set of cell-specific parameters (cell-specifc) ( and ).
对于位于RRH或Macro中心的用户设备，可以仅配置一组用户专用(UE-specific)参数。例如，在RRH2中心的用户设备，配置的用户专用的参数为(和)。For the user equipment located in the RRH or Macro center, only a set of user-specific (UE-specific) parameters can be configured. For example, in the user equipment in the RRH2 center, the configured user-specific parameters are ( and ).
对于位于RRH或Macro覆盖边缘用户，可以配置多组参数。例如，配置2组参数，其中1组可为小区共有(cell-specifc)参数，1组为用户专用的(UE-specific)参数。例如，RRH1边缘用户，可配置和和For users at the edge of RRH or Macro coverage, multiple sets of parameters can be configured. For example, two sets of parameters are configured, one set may be cell-specific (cell-specific) parameters, and the other set may be user-specific (UE-specific) parameters. For example, RRH1 edge users can configure and and
基站根据实际的调度情况，动态选择最优的参数配置。例如，当PUCCH仅被RRH1接收时，可选择和而PUCCH被RRH1和Macro eNB同时接收时，可选择和The base station dynamically selects the optimal parameter configuration according to the actual scheduling situation.

实例4：Example 4:
图15是本发明实施例18的场景示意图。Fig. 15 is a schematic diagram of a scene according to Embodiment 18 of the present invention.
如图15所示，当整个小区中在某一时刻，同时调度的用户设备为RRH2中心用户设备，RRH1的中心用户设备及RRH1边缘用户设备，为该边缘用户设备配置2组参数，如配置一组小区共有的参数，再配置一组用户专用的参数。As shown in Figure 15, when in the entire cell at a certain moment, the user equipments scheduled at the same time are RRH2 central user equipment, RRH1 central user equipment and RRH1 edge user equipment, configure two sets of parameters for the edge user equipment, such as configuring a Configure the parameters common to the group of cells, and then configure a group of user-specific parameters.
此时，基站选择用户专用的参数和与RRH1中心用户设备采用相同的CAZAC序列，从而达到完全正交的效果，与RRH2中心用户设备采用不同的CAZAC序列，达到干扰随机化的效果。At this time, the base station selects user-specific parameters and The same CAZAC sequence is used for the central user equipment of RRH1, so as to achieve the effect of complete orthogonality, and a different CAZAC sequence is used for the central user equipment of RRH2, so as to achieve the effect of interference randomization.
由于该3个用户设备PUCCH占用的PRB资源在相同区域内，可达到提高PUCCH资源利用率的效果。Since the PRB resources occupied by the PUCCHs of the three user equipments are in the same area, the effect of improving the utilization rate of the PUCCH resources can be achieved.
实例5：Example 5:
图16是本发明实施例19的场景示意图。Fig. 16 is a schematic diagram of a scene according to Embodiment 19 of the present invention.
若整个小区内低版本用户设备(传统UE)较多，或配置为小区共有的参数(和)的用户设备较多，则为均匀负载，可动态的指示用户设备在相对负载较少的资源上发送PUCCH。If there are many low-version user equipments (traditional UEs) in the entire cell, or configured as parameters shared by the cell ( and ) has a large number of user equipments, the load is uniform, and the user equipment can be dynamically instructed to send the PUCCH on resources with relatively less load.
例如，RRH1的边缘用户设备，为该边缘用户设备配置2组参数，如配置一组小区共有的参数，再配置一组用户专用的参数。For example, the edge user equipment of RRH1 configures two sets of parameters for the edge user equipment, such as configuring a set of parameters common to cells, and configuring a set of user-specific parameters.
此时若在对应的物理资源上的PUCCH负载较少，基站为该UE选择(和)。If at this time The PUCCH load on the corresponding physical resource is less, and the base station selects ( and ).
反之，若在对应的物理资源上的PUCCH负载较多，则基站为该用户设备选择(和)。Conversely, if in If the PUCCH load on the corresponding physical resource is relatively large, the base station selects ( and ).
实例6：Example 6:
图17是本发明实施例20的场景示意图。Fig. 17 is a schematic diagram of a scene according to Embodiment 20 of the present invention.
如图17所示，若在整个小区中，存在多个用户设备，其PUCCH被多个点接收。如图17所示，RRH1边缘用户设备的PUCCH同时被Macro eNB和RRH1接收，而RRH2边缘用户设备的PUCCH同时被Macro eNB和RRH2接收，那么，这两个用户设备若调度在相同的PRB资源上，必须使用相同的CAZAC序列，例如，基站为这2个用户设备均选择参数(和)。As shown in FIG. 17 , if there are multiple user equipments in the entire cell, their PUCCHs are received by multiple points. As shown in Figure 17, the PUCCH of RRH1 edge user equipment is received by Macro eNB and RRH1 at the same time, and the PUCCH of RRH2 edge user equipment is received by Macro eNB and RRH2 at the same time, then, if the two user equipments are scheduled on the same PRB resource , the same CAZAC sequence must be used, for example, the base station selects parameters ( and ).
实例7：Example 7:
对于用户设备ACK/NACK反馈的PUCCH，例如forma1/1a/1b，基站可为用户设备配置多组参数。每组参数至少包含物理资源指示索引与虚拟小区标识NID。For the PUCCH fed back by user equipment ACK/NACK, such as form1/1a/1b, the base station can configure multiple sets of parameters for the user equipment. Each set of parameters contains at least physical resource indication index and the virtual cell identifier NID .
对于用户设备CSI反馈的PUCCH，例如format 2/2a/2b，基站可为用户设备配置多组参数。每组参数至少包含物理资源指示索引与虚拟小区标识NID。For the PUCCH fed back by the CSI of the user equipment, such as format 2/2a/2b, the base station can configure multiple sets of parameters for the user equipment. Each set of parameters contains at least physical resource indication index and the virtual cell identifier NID .
不同的format的参数配置可以是独立的，也可以是绑定在一起的。The parameter configurations of different formats can be independent or bound together.
当独立配置时，多组参数的数目可以是不同的，也可以相同。例如，可为format1a/1b配置3组参数，而为format 2a/2b配置2组参数，且format 1a/1b的虚拟小区标识NID与format 2a/2b的虚拟小区标识NID没有一一对应关系。When configured independently, the number of multiple sets of parameters can be different or the same. For example, 3 sets of parameters can be configured for format1a/1b, and 2 sets of parameters can be configured for format 2a/2b, and there is no one-to-one correspondence between the virtual cell ID NID of format 1a/1b and the virtual cell ID NID of format 2a/2b .
当绑定配置时，用于CSI反馈的PUCCH，与仅承载ACK/NACK反馈的PUCCH format配置的虚拟小区标识NID相同，但物理资源指示索引需单独配置，且与一一对应。When binding configuration, the PUCCH used for CSI feedback is the same as the virtual cell identifier NID configured in the PUCCH format that only carries ACK/NACK feedback, but the physical resource indicates the index need to be configured separately, and and One to one correspondence.
当动态调度的PDSCH的ACK/NACK与CSI反馈同时发送时，基站可通过调度该PDSCH的DCI动态指示用户使用哪一套资源发送PUCCH。例如，在第n时刻PDCCH承载的DCI动态指示n+4时刻的PUCCH format 1a所使用的PUCCH参数为与那么在n+m时刻的PUCCHformat 2所使用的参数为与其中m为大于4的最小整数。在这种情况下，DCI指示PUCCH format 1a的参数，而PUCCH format 2所使用的参数默认与PUCCH format 1a参数绑定的，即一个DCI指示PUCCH format 1a和2的参数。When the ACK/NACK of the dynamically scheduled PDSCH and the CSI feedback are sent at the same time, the base station can dynamically instruct the user which set of resources to use to send the PUCCH by scheduling the DCI of the PDSCH. For example, at the nth moment, the DCI carried by the PDCCH dynamically indicates that the PUCCH parameter used by the PUCCH format 1a at the n+4 moment is and Then the parameters used by PUCCHformat 2 at time n+m are and Where m is the smallest integer greater than 4. In this case, the DCI indicates the parameters of PUCCH format 1a, and the parameters used by PUCCH format 2 are bound with the parameters of PUCCH format 1a by default, that is, one DCI indicates the parameters of PUCCH format 1a and 2.
对于仅承载CSI反馈的PUCCH format所使用的参数，例如format 2，可使用与最近指示的与对应的与For the parameters used by the PUCCH format that only carries CSI feedback, such as format 2, the latest indicated and corresponding and
