本发明涉及通信技术领域，特别涉及一种信息发送方法、用户设备和基站。The present invention relates to the field of communication technology, in particular to an information sending method, user equipment and base station.
背景技术Background technique
随着通信技术的飞速发展，宽带码分多址作为第三代移动通信系统的主流技术之一，在全球范围内得到了广泛的研究和应用。目前3GPP已经有第6版本(Release6，R6)、第7版本(Release7，R7)……第11版本(Release11，R11)等。为了提高数据传输速率，满足不同的需求，UMTS(UniversalMobileTelecommunicationsSystem，通用移动通信系统)在R5中引入了高速下行分组接入(HighSpeedDownlinkPacketAccess，HSDPA)技术，使得下行链路能够实现高达14.4Mbit/s的速度；在R6中引入了高速上行分组接入(HighSpeedUplinkPacketAccess，HSUPA)。为了进一步提高HSPA系统的数据传输速率，在R8版本中引入了DC-HSDPA(Dual-CellHSDPA，双小区HSDPA)技术，即采用下行两载波，上行单载波配置，UE可以同时接收两个下行载波的高速下行共享通道(HS-DSCH，HighSpeedDownlinkSharedChannel)发送的数据；其中与上行载波相关联的下行载波称为主载波，另外一个载波称为辅载波。With the rapid development of communication technology, wideband code division multiple access, as one of the mainstream technologies of the third generation mobile communication system, has been widely researched and applied all over the world. At present, 3GPP already has version 6 (Release6, R6), version 7 (Release7, R7) ... version 11 (Release11, R11) and so on. In order to increase the data transmission rate and meet different needs, UMTS (Universal Mobile Telecommunications System, Universal Mobile Communications System) introduced High Speed Downlink Packet Access (HSDPA) technology in R5, enabling the downlink to achieve a speed of up to 14.4Mbit/s ; High-speed uplink packet access (HighSpeedUplinkPacketAccess, HSUPA) is introduced in R6. In order to further improve the data transmission rate of the HSPA system, the DC-HSDPA (Dual-CellHSDPA, dual-cell HSDPA) technology was introduced in the R8 version, that is, the configuration of two downlink carriers and an uplink single carrier is adopted, and the UE can receive signals from two downlink carriers at the same time. Data sent by a high-speed downlink shared channel (HS-DSCH, HighSpeedDownlinkSharedChannel); the downlink carrier associated with the uplink carrier is called the primary carrier, and the other carrier is called the secondary carrier.
R9版本中对HSPA多载波技术继续演进，引入了DC-HSUPA(Dual-CellHSUPA，双小区HSUPA)技术，即：采用上行两载波，UE可以使用两个上行载波的增强专用信道(E-DCH，EnhancedDedicatedChannel)发送上行数据；其中一个载波为上行主载波，该上行主载波用于承载对该下行主载波进行功率控制的TPC命令，另外一个载波为上行辅载波，跟一个下行辅载波相对应。在每个上行载波上，分别独立进行上行功率控制和下行功率控制。图1a为基站与用户设备形成的架构示意图，其中，基站30与用户设备10的交互过程中，为了通过功率控制以实现通信。In the R9 version, the HSPA multi-carrier technology continues to evolve, and the DC-HSUPA (Dual-CellHSUPA, dual-cell HSUPA) technology is introduced, that is, two uplink carriers are used, and the UE can use the enhanced dedicated channel (E-DCH, EnhancedDedicatedChannel) to send uplink data; one of the carriers is an uplink primary carrier, and the uplink primary carrier is used to carry TPC commands for power control of the downlink primary carrier, and the other carrier is an uplink secondary carrier, corresponding to a downlink secondary carrier. On each uplink carrier, uplink power control and downlink power control are independently performed. FIG. 1 a is a schematic diagram of a structure formed by a base station and a user equipment, wherein, during an interaction process between a base station 30 and a user equipment 10 , power control is used to implement communication.
在采用DC-HSUPA技术的通信系统中，发射功率资源是各个载波之间共享的。由于一个载波占用功率必定造成另一个载波可使用的功率减少，因此如何在多载波模式下在保证TPC的接收性能，成为多载波技术当前中亟待解决的问题之一。In a communication system using DC-HSUPA technology, transmit power resources are shared among carriers. Since the power occupied by one carrier will inevitably reduce the available power of another carrier, how to ensure the receiving performance of the TPC in the multi-carrier mode has become one of the problems to be solved urgently in the current multi-carrier technology.

为使本发明的目的、技术方案和优点更加清楚，下面将结合附图对本发明实施方式作进一步地详细描述。In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.
图1b是本发明实施例提供的一种信息发送方法的流程图。该实施例的执行主体为UE(UserEquipment，用户设备)，参见图1b，包括：Fig. 1b is a flowchart of an information sending method provided by an embodiment of the present invention. The execution subject of this embodiment is UE (UserEquipment, user equipment), referring to FIG. 1b, including:
101、通过上行主载波发送第一专用物理控制信道DPCCH给基站，该第一DPCCH用于承载第一信息，该第一信息至少包括：第一导频Pilot信息、第一传输功率控制TPC命令。101. Send a first dedicated physical control channel DPCCH to a base station through an uplink primary carrier, where the first DPCCH is used to carry first information, and the first information includes at least: first pilot information and a first transmission power control TPC command.
其中，第一TPC命令携带请求基站升高还是降低下行发射功率的信息。Wherein, the first TPC command carries information requesting the base station to increase or decrease downlink transmit power.
当基站获取到第一Pilot信息后，根据Pilot信息进行信干噪比估计，然后跟目标信干噪比进行比较，根据比较结果，判决抬高还是降低UE下一时刻的上行发射功率，然后下发TPC命令，来调整UE下一时刻的上行发射功率。After the base station obtains the first Pilot information, it estimates the SINR according to the Pilot information, and then compares it with the target SINR. Send a TPC command to adjust the uplink transmission power of the UE at the next moment.
102、通过上行辅载波发送第二DPCCH给该基站，该第二DPCCH用于承载第二信息，该第二信息至少包括：第二Pilot信息和第二TPC命令，该第二TPC命令的命令内容与该第一TPC命令的命令内容相同，该第一TPC命令和该第二TPC命令用于使该基站根据该第一TPC命令和该第二TPC命令中的至少一个命令，对与该上行主载波相对应的下行主载波进行功率控制。102. Send a second DPCCH to the base station through an uplink secondary carrier, where the second DPCCH is used to carry second information, where the second information includes at least: second Pilot information and a second TPC command, and the command content of the second TPC command The command content of the first TPC command is the same as that of the first TPC command, and the first TPC command and the second TPC command are used to enable the base station to communicate with the uplink master according to at least one of the first TPC command and the second TPC command. The downlink primary carrier corresponding to the carrier performs power control.
其中，基站在接收到第一TPC命令和第二TPC命令时，可以根据其中至少一个TPC命令进行功率控制，如仅根据第一TPC命令进行功率控制，或根据第二TPC命令进行功率控制，又或者，根据第一TPC命令和第二TPC命令，得到下行TPC。Wherein, when the base station receives the first TPC command and the second TPC command, it may perform power control according to at least one of the TPC commands, such as performing power control only according to the first TPC command, or performing power control according to the second TPC command, and Or, obtain the downlink TPC according to the first TPC command and the second TPC command.
需要说明的是，上述步骤101-102是在同一时刻内进行。It should be noted that the above steps 101-102 are performed at the same time.
本发明实施例中，当UE配置为上行多载波模式时，可以通过上行主载波和上行辅载波发送对下行主载波的TPC命令，避免了对下行辅载波的发射功率进行控制，由于在辅载波上简化了控制信息指示、数据发送、数据调度和信道状态反馈等信息，优化了系统性能。In the embodiment of the present invention, when the UE is configured in the uplink multi-carrier mode, the TPC command for the downlink primary carrier can be sent through the uplink primary carrier and the uplink secondary carrier, avoiding the control of the transmit power of the downlink secondary carrier. It simplifies information such as control information indication, data transmission, data scheduling, and channel state feedback, and optimizes system performance.
如果在上行主辅载波上均不支持DCH(DedicatedChannel，专用信道)业务，只支持E-DCH业务，则该第一DPCCH(DedicatedPhysicalControlChannel，专用物理控制信道)承载的信息可以仅包括第一导频Pilot信息、第一TPC命令，而如果考虑支持DCH业务的情况下，则该第一DPCCH承载的信息可以包括第一导频Pilot信息、第一TPC命令、TFCI(TransportFormatCombinationIndicator，传输格式组合标识符)和FBI(FeedbackInformation，反馈信息)。If neither the DCH (Dedicated Channel, dedicated channel) service is supported on the uplink primary and secondary carriers, but only the E-DCH service is supported, the information carried by the first DPCCH (DedicatedPhysicalControlChannel, dedicated physical control channel) may only include the first pilot frequency Pilot information, the first TPC command, and if the DCH service is considered, the information carried by the first DPCCH may include the first pilot Pilot information, the first TPC command, TFCI (TransportFormatCombinationIndicator, transport format combination identifier) and FBI (FeedbackInformation, feedback information).
在UE通过上行主载波向基站发送第一信息，而在上行辅载波上发送第二信息的情况可以有以下任一种：When the UE sends the first information to the base station through the uplink primary carrier, and sends the second information on the uplink secondary carrier, any of the following may occur:
(一)所述第二信息为第二Pilot信息和第二TPC命令；(1) The second information is the second Pilot information and the second TPC command;
在本发明实施例中，当UE配置为上行多载波模式时，主辅载波均不支持DCH，只支持E-DCH业务，因此在上行辅载波上，可以发送承载第二信息的DPCCH，该第二信息为第二pilot信息和第二TPC命令。In the embodiment of the present invention, when the UE is configured in the uplink multi-carrier mode, the primary and secondary carriers do not support DCH, and only support E-DCH services. Therefore, on the uplink secondary carrier, a DPCCH carrying the second information can be sent. The second information is the second pilot information and the second TPC command.
由于UE发送仅承载第二pilot信息和第二TPC命令的S-DPCCH，而不再承载TFCI(TransportFormatCombinationIndicator，传输格式组合标识符)和FBI(FeedbackInformation，反馈信息)，由于携带的信息域减少，而降低了上行发射功率。Since the UE sends the S-DPCCH that only carries the second pilot information and the second TPC command, and no longer carries TFCI (TransportFormatCombinationIndicator, transport format combination identifier) and FBI (FeedbackInformation, feedback information), due to the reduction of the information field carried, and Reduced uplink transmit power.
具体地，在上行辅载波使用单天线发射模式时，UE通过上行辅载波发送第二DPCCH给所述基站，所述第二DPCCH用于承载第二信息，所述第二信息为第二Pilot信息和第二TPC命令；Specifically, when the uplink auxiliary carrier uses a single-antenna transmission mode, the UE sends a second DPCCH to the base station through the uplink auxiliary carrier, and the second DPCCH is used to carry second information, and the second information is the second Pilot information and a second TPC command;
如果上行辅载波使用发射分集模式，通过上行辅载波发送S-DPCCH给所述基站，该S-DPCCH用于承载第二信息，所述第二信息为第二Pilot信息和第二TPC命令。If the uplink secondary carrier uses the transmit diversity mode, the S-DPCCH is sent to the base station through the uplink secondary carrier, and the S-DPCCH is used to carry second information, and the second information is the second Pilot information and the second TPC command.
(二)所述第二信息为所述第二Pilot信息、第二TPC命令和传输格式组合指示TFCI信息。由于UE发送仅承载第二pilot信息、第二TPC命令和TFCI的第二DPCCH，而不再承载FBI，由于携带的信息域减少，而降低了上行发射功率。(2) The second information is the second Pilot information, the second TPC command, and the transport format combination indication TFCI information. Since the UE sends the second DPCCH carrying only the second pilot information, the second TPC command, and the TFCI instead of carrying the FBI, the uplink transmission power is reduced due to the reduction of the carried information field.
(三)所述第二信息为所述第二Pilot信息、第二TPC命令和反馈信息FBI信息。(3) The second information is the second Pilot information, the second TPC command and feedback information FBI information.
由于UE发送仅承载第二pilot信息、第二TPC命令和FBI的第二DPCCH，而不再承载TFCI，由于携带的信息域减少，而降低了上行发射功率。Since the UE sends the second DPCCH that only carries the second pilot information, the second TPC command and the FBI, and does not carry the TFCI, the uplink transmission power is reduced due to the reduction of the carried information field.
可选地，基于图1的实施例技术方案的基础上，该第一TPC命令和该第二TPC命令具体用于使该基站根据该第一TPC命令和该第二TPC命令中的至少一个命令，对该下行主载波所承载的第一控制信道和第二控制信道进行功率控制，该第一控制信道用于承载对该上行主载波进行功率控制的上行TPC命令，该第二控制信道用于承载对该上行辅载波进行功率控制的上行TPC命令。Optionally, on the basis of the technical solution of the embodiment in FIG. 1 , the first TPC command and the second TPC command are specifically used to make the base station according to at least one of the first TPC command and the second TPC command , performing power control on the first control channel and the second control channel carried by the downlink main carrier, the first control channel is used to carry the uplink TPC command for power control on the uplink main carrier, and the second control channel is used for Carries an uplink TPC command for performing power control on the uplink secondary carrier.
该第一TPC命令和第二TPC命令可以是对第一控制信道和第二控制信道均进行功率控制，还可以是分别进行控制，如第一TPC命令用于对第一控制信道进行功控，而第二TPC命令用于对第二控制信道进行功控，在后续实施例中会详细说明。其中，所述第一控制信道和所述第二控制信道为F-DPCH(FractionalDedicatedPhysicalChannel，分数专用物理信道)、E-AGCH(E-DCHAbsoluteGrantChannel，E-DCH绝对授权信道)、E-RGCH(E-DCHRelativeGrantChannel，E-DCH相对授权信道)、E-HICH(E-DCHHybridARQIndicatorChannel，E-DCH混合自动重传指示信道)中的任一种。优选地，该第一控制信道和第二控制信道均为F-DPCH。其中，E-DCH(EnhancedDedicatedChannel)用于指代上行增强专用信道信息。The first TPC command and the second TPC command may perform power control on both the first control channel and the second control channel, and may also perform power control separately. For example, the first TPC command is used to perform power control on the first control channel, The second TPC command is used to perform power control on the second control channel, which will be described in detail in subsequent embodiments. Wherein, the first control channel and the second control channel are F-DPCH (FractionalDedicatedPhysicalChannel, Fractional Dedicated Physical Channel), E-AGCH (E-DCHAbsoluteGrantChannel, E-DCH Absolute Grant Channel), E-RGCH (E- Any one of DCHRelativeGrantChannel, E-DCH relative grant channel), E-HICH (E-DCHHybridARQIndicatorChannel, E-DCH hybrid automatic repeat indicator channel). Preferably, both the first control channel and the second control channel are F-DPCH. Wherein, E-DCH (EnhancedDedicatedChannel) is used to refer to uplink enhanced dedicated channel information.
图2是本发明实施例提供的一种发射功率控制方法的流程图。该实施例的执行主体为基站，参见图2，包括：Fig. 2 is a flowchart of a transmission power control method provided by an embodiment of the present invention. The executive body of this embodiment is the base station, referring to Figure 2, including:
201、接收用户设备通过上行主载波发送的第一专用物理控制信道DPCCH，并通过该第一DPCCH获取第一信息，该第一信息至少包括：第一导频Pilot信息和第一传输功率控制TPC命令。201. Receive the first dedicated physical control channel DPCCH sent by the user equipment through the uplink primary carrier, and obtain first information through the first DPCCH, where the first information includes at least: first pilot Pilot information and first transmission power control TPC Order.
202、接收该用户设备通过上行辅载波发送的第二DPCCH，并通过该第二DPCCH获取第二信息，该第二信息至少包括：第二Pilot信息和第二TPC命令，该用户设备发送的该第一TPC命令的命令内容和该第二TPC命令的命令内容相同。202. Receive a second DPCCH sent by the user equipment through an uplink secondary carrier, and acquire second information through the second DPCCH, where the second information includes at least: second Pilot information and a second TPC command, and the second information sent by the user equipment The command content of the first TPC command is the same as that of the second TPC command.
203、根据该第一TPC命令和该第二TPC命令中的至少一个命令，对与该上行主载波相对应的下行主载波进行功率控制。203. Perform power control on a downlink main carrier corresponding to the uplink main carrier according to at least one of the first TPC command and the second TPC command.
本发明实施例中，为了节约信令开销，只对下行主载波进行功率控制，而不对下行的辅载波不单独做功率控制，由于传输过程中的功率损失等情况，基站对上行主载波所承载的TPC接收性能可能降低，为了避免这种情况的发生，可以通过上述主载波和辅载波承载相同的下行TPC，以便在接收后的处理过程中能够提高解调效率，从而提高基站的TPC接收性能。In the embodiment of the present invention, in order to save signaling overhead, only power control is performed on the downlink main carrier, and no power control is performed on the downlink auxiliary carrier separately. The receiving performance of the TPC may be reduced. In order to avoid this situation, the same downlink TPC can be carried by the above-mentioned main carrier and auxiliary carrier, so that the demodulation efficiency can be improved in the processing process after receiving, thereby improving the TPC receiving performance of the base station .
可选地，基于图2所述实施例技术方案的基础上，该步骤203“根据该第一TPC命令和该第二TPC命令中的至少一个命令，对与该上行主载波相对应的下行主载波进行功率控制”可以包括：Optionally, based on the technical solution of the embodiment described in FIG. 2 , in step 203 "according to at least one of the first TPC command and the second TPC command, perform Carrier power control" may include:
2031、对所述第一TPC命令和所述第二TPC命令进行TPC合并，得到下行TPC命令。2031. Perform TPC combination on the first TPC command and the second TPC command to obtain a downlink TPC command.
具体地，TPC合并可以包括：分别计算第一TPC命令和第二TPC命令的软值，该软值表示TPC命令为+1(提高发射功率)或者为-1(降低发射功率)的概率，然后将两个TPC命令的软值相加，最后对合并后的TPC命令的软值进行判决，得到下行TPC命令。Specifically, the TPC merging may include: respectively calculating soft values of the first TPC command and the second TPC command, where the soft value represents the probability that the TPC command is +1 (increase transmit power) or -1 (decrease transmit power), and then The soft values of the two TPC commands are added, and finally the soft value of the combined TPC command is judged to obtain the downlink TPC command.
2032、利用所述下行TPC命令对所述下行主载波所承载的第一控制信道和第二控制信道进行功率控制，所述第一控制信道用于承载对所述上行主载波进行功率控制的上行TPC命令，所述第二控制信道用于承载对所述上行辅载波进行功率控制的上行TPC命令。2032. Use the downlink TPC command to perform power control on the first control channel and the second control channel carried by the downlink primary carrier, where the first control channel is used to carry an uplink channel that performs power control on the uplink primary carrier A TPC command, the second control channel is used to carry an uplink TPC command for performing power control on the uplink secondary carrier.
需要说明的是，与上行辅载波相对应的控制信道F-DPCH、E-AGCH、E-RGCH和E-HICH均可以在下行主载波上传输，因此，可以通过上行主载波所承载的下行TPC对该多个控制信道中的任一个进行功率控制，优选地，对于与主载波相对应的控制信道F-DPCH、E-AGCH、E-RGCH和E-HICH，下行TPC可以是用于对F-DPCH信道进行功率控制，其他控制信道的功率相对于F-DPCH信道有一个固定的功率偏置。另外，由于上行主载波只承载一个用于下行功率控制的TPC，因此将所述第二控制信道的功率设置为与所述第一控制信道有一个固定的功率偏置。It should be noted that the control channels F-DPCH, E-AGCH, E-RGCH and E-HICH corresponding to the uplink auxiliary carrier can all be transmitted on the downlink main carrier, therefore, the downlink TPC carried by the uplink main carrier can Perform power control on any one of the multiple control channels. Preferably, for the control channels F-DPCH, E-AGCH, E-RGCH and E-HICH corresponding to the main carrier, the downlink TPC can be used to control the F - The DPCH channel performs power control, and the power of other control channels has a fixed power offset relative to the F-DPCH channel. In addition, since the uplink primary carrier only carries one TPC for downlink power control, the power of the second control channel is set to have a fixed power offset with the first control channel.
可选地，基于图2所述实施例技术方案的基础上，该步骤2032“所述利用所述下行TPC命令对所述下行主载波所承载的第一控制信道和第二控制信道进行功率控制”，包括：Optionally, based on the technical solution of the embodiment described in FIG. 2 , in step 2032 "using the downlink TPC command to perform power control on the first control channel and the second control channel carried by the downlink main carrier ",include:
2032-1、根据所述下行TPC命令，在所述第一控制信道在上一时刻的功率的基础上进行功率调整，得到所述第一控制信道在当前时刻的功率；2032-1. According to the downlink TPC command, perform power adjustment on the basis of the power of the first control channel at the previous moment to obtain the power of the first control channel at the current moment;
2032-2、将得到的所述第一控制信道在当前时刻的功率加上一个预设的功率偏置，作为所述第二控制信道在当前时刻的功率。2032-2. Add a preset power offset to the obtained power of the first control channel at the current moment, and use it as the power of the second control channel at the current moment.
基站通过接收到的导频可以进行对上一时刻的信干噪比估计，从而与目标信干噪比进行比较，以确定基站获取到该下行TPC命令时，可以根据下行TPC命令所指示的功率调整方式(提高或降低)对第一控制信道进行功率调整，从而得到并根据预设的功率偏置和第一控制信道的功率，将第二控制信道的功率设置为与第一控制信道具有固定功率偏置的功率。如，当预设的功率偏置为0时，第一控制信道跟第二控制信道的功率相同。The base station can estimate the SINR at the previous moment through the received pilot, and compare it with the target SINR to determine that when the base station obtains the downlink TPC command, it can use the power indicated by the downlink TPC command The adjustment method (increase or decrease) adjusts the power of the first control channel, thereby obtaining and according to the preset power offset and the power of the first control channel, the power of the second control channel is set to have a fixed frequency with the first control channel. The power of the power bias. For example, when the preset power offset is 0, the power of the first control channel is the same as that of the second control channel.
可选地，基于图2所述实施例技术方案的基础上，该步骤203“根据该第一TPC命令和该第二TPC命令中的至少一个命令，对与该上行主载波相对应的下行主载波进行功率控制”可以包括：Optionally, based on the technical solution of the embodiment described in FIG. 2 , in step 203 "according to at least one of the first TPC command and the second TPC command, perform Carrier power control" may include:
2033、根据所述第一TPC命令，在所述第一控制信道在上一时刻的功率的基础上进行功率调整，得到所述第一控制信道在当前时刻的功率。2033. According to the first TPC command, perform power adjustment on the basis of the power of the first control channel at the previous moment to obtain the power of the first control channel at the current moment.
2034、根据所述第二TPC命令，在所述第二控制信道在上一时刻的功率的基础上进行功率调整，得到所述第二控制信道在当前时刻的功率。2034. According to the second TPC command, perform power adjustment on the basis of the power of the second control channel at the previous moment to obtain the power of the second control channel at the current moment.
对于步骤2033和2034，第一TPC命令仅用于对第一控制信道进行功率控制，而第二TPC命令则用于对第二控制信道进行功率控制。对于通信过程来说，第一控制信道和第二控制信道在同一时刻的功率不一定相同，也即是说明，通过根据第一TPC命令和第二TPC命令进行调整后的第一控制信道和第二控制信道的功率也可以不相同，以达到对载波功率的灵活分配的目的。For steps 2033 and 2034, the first TPC command is only used to perform power control on the first control channel, while the second TPC command is used to perform power control on the second control channel. For the communication process, the power of the first control channel and the second control channel at the same time are not necessarily the same, that is to say, the first control channel and the second control channel adjusted according to the first TPC command and the second TPC command The power of the two control channels can also be different, so as to achieve the purpose of flexible allocation of carrier power.
当然，在本发明实施例提供的另一个实施例中，下行TPC还可以是用于所述基站对所述下行主载波所承载的第一控制信道进行功率控制，第一控制信道上承载两个分别跟上行主辅载波相关联的功率控制信息。第一控制信道为F-DPCH信道。在本发明实施例中，基站可以认为下行TPC命令不仅用于对下行主载波的发射功率进行功率控制，还可以用于对下行辅载波的发射功率进行功率控制。Of course, in another embodiment provided by the embodiment of the present invention, the downlink TPC can also be used for the base station to perform power control on the first control channel carried by the downlink main carrier, and the first control channel carries two Power control information associated with the uplink primary and secondary carriers respectively. The first control channel is the F-DPCH channel. In the embodiment of the present invention, the base station may consider that the downlink TPC command is not only used to perform power control on the transmit power of the downlink primary carrier, but also used to perform power control on the transmit power of the downlink secondary carrier.
图3是本发明实施例提供的一种信息发送方法的流程图。参见图3，该方法的交互双方为用户设备和基站，则该方法具体包括：Fig. 3 is a flowchart of an information sending method provided by an embodiment of the present invention. Referring to FIG. 3, the interaction parties of the method are the user equipment and the base station, and the method specifically includes:
301、用户设备通过上行主载波发送第一专用物理控制信道DPCCH给基站，所述第一DPCCH用于承载第一信息；以及，通过上行辅载波发送第二DPCCH给所述基站，所述第二DPCCH用于承载第二信息；所述第一信息至少包括：第一导频Pilot信息、第一传输功率控制TPC命令，所述第二信息至少包括：第二Pilot信息和第二TPC命令，所述第二TPC命令的命令内容与所述第一TPC命令的命令内容相同，301.

本发明实施例中，为了节约信令开销，只对下行主载波进行功率控制，而不对下行的辅载波不单独做功率控制，由于传输过程中的功率损失等情况，基站对上行主载波所承载的TPC接收性能可能降低，为了避免这种情况的发生，可以通过上述主载波和辅载波承载相同的下行TPC，以便在接收后的处理过程中能够提高解调效率，从而提高基站的TPC接收性能。In the embodiment of the present invention, in order to save signaling overhead, only power control is performed on the downlink main carrier, and no power control is performed on the downlink auxiliary carrier separately. The receiving performance of the TPC may be reduced. In order to avoid this situation, the same downlink TPC can be carried by the above-mentioned main carrier and auxiliary carrier, so that the demodulation efficiency can be improved in the processing process after receiving, thereby improving the TPC receiving performance of the base station .
图4是本发明实施例提供的一种信息发送方法的流程图。参见图4，所述方法包括：Fig. 4 is a flowchart of an information sending method provided by an embodiment of the present invention. Referring to Figure 4, the method includes:
401、通过上行主载波发送第一专用物理控制信道DPCCH给基站，所述第一DPCCH用于承载第一信息，所述第一信息至少包括：第一导频Pilot信息、下行传输功率控制命令TPC命令，所述下行TPC用于使所述基站对与所述上行主载波相对应的下行主载波所承载的第一控制信道和第二控制信道进行功率控制，所述第一控制信道用于承载对所述上行主载波进行功率控制的上行TPC命令，所述第二控制信道用于承载对所述上行辅载波进行功率控制的上行TPC命令。401. Send a first dedicated physical control channel DPCCH to the base station through an uplink primary carrier, where the first DPCCH is used to carry first information, and the first information includes at least: first pilot pilot information, downlink transmission power control command TPC command, the downlink TPC is used to enable the base station to perform power control on the first control channel and the second control channel carried by the downlink main carrier corresponding to the uplink main carrier, and the first control channel is used to carry An uplink TPC command for performing power control on the uplink main carrier, and the second control channel is used to carry an uplink TPC command for performing power control on the uplink auxiliary carrier.
402、通过上行辅载波发送第二DPCCH给所述基站，第二DPCCH包括pilot域和第一域，所述pilot域用于承载第二pilot信息，所述第一域用于承载固定比特。402. Send a second DPCCH to the base station through an uplink secondary carrier, where the second DPCCH includes a pilot field and a first field, the pilot field is used to carry second pilot information, and the first field is used to carry fixed bits.
其中，所述第一域可以为TPC域，或者为固定fixed域，关于TPC域和fixed域的详细描述可以参考3GPP协议，这里不再赘述。Wherein, the first domain may be a TPC domain or a fixed fixed domain. For detailed descriptions of the TPC domain and the fixed domain, reference may be made to the 3GPP protocol, which will not be repeated here.
本实施例中，当所述第一域为TPC域时，所述第二DPCCH还可以包括反馈信息FBI域，其中，所述FBI域用于承载FBIIn this embodiment, when the first field is the TPC field, the second DPCCH may further include a feedback information FBI field, where the FBI field is used to bear the FBI
本实施例中，该固定比特对于基站和UE是已知的，该固定比特具体可以为比特序列‘10’，该固定比特可以与导频信息起相同的作用。In this embodiment, the fixed bit is known to the base station and the UE, the fixed bit may specifically be a bit sequence '10', and the fixed bit may have the same function as the pilot information.
为了更好地说明本发明实施例的技术方案，以下结合不同的业务模式，对第二DPCCH上承载的信息做简要介绍，在本实施例的一种实施方式中，第二DPCCH承载的信息可以有以下形式：In order to better illustrate the technical solution of the embodiment of the present invention, the information carried on the second DPCCH is briefly introduced below in combination with different service modes. In an implementation manner of this embodiment, the information carried by the second DPCCH can be There are the following forms:
(一)第二DPCCH承载的信息为第二Pilot信息；(1) The information carried by the second DPCCH is the second Pilot information;
在本发明实施例中，当UE配置为上行多载波模式时，主辅载波均不支持DCH，只支持E-DCH业务，因此在上行辅载波上，可以发送承载第二导频pilot信息的DPCCH。In the embodiment of the present invention, when the UE is configured in the uplink multi-carrier mode, the primary and secondary carriers do not support DCH, and only support E-DCH services. Therefore, the DPCCH carrying the second pilot pilot information can be sent on the uplink secondary carrier .
由于UE发送仅承载导频pilot的S-DPCCH，而不再承载TFCI(TransportFormatCombinationIndicator，传输格式组合标识符)和FBI(FeedbackInformation，反馈信息)，由于携带的信息域减少，而降低了上行发射功率。Since the UE sends the S-DPCCH carrying only the pilot pilot, instead of carrying TFCI (TransportFormatCombinationIndicator, transport format combination identifier) and FBI (FeedbackInformation, feedback information), the uplink transmission power is reduced due to the reduction of the information field carried.
