可选的，所述用户设备也可获取所述服务基站配置的下行路损参考关联信息，该下行路损参考关联信息指示所述用户设备在估算下行路损、计算PH、PUCCH/PUSCH发射功率、探测参考信号（SRS）发射功率时所使用的关联信息；其中，所述下行路损参考关联信息可以与所述上行CoMP测量集合相关联，用以指示所述用户设备按照CoMP测量集合估算下行路损，同时也用以指示所述用户设备按照CoMP测量集合对应的上行功率控制参数计算PH、PUCCH/PUSCH发射功率；当系统在配置了载波聚合（CA）时，所述下行路损参考关联信息可以为主服务小区（PCell）、辅服务小区（SCell）或上行CoMP测量集合；在未配置CA时，所述下行路损参考关联信息可以为PCell或上行CoMP测量集合。Optionally, the user equipment may also obtain downlink path loss reference association information configured by the serving base station, the downlink path loss reference association information indicating that the user equipment is estimating downlink path loss, calculating PH, PUCCH/PUSCH transmission power . Association information used when sounding reference signal (SRS) transmit power; wherein, the downlink path loss reference association information may be associated with the uplink CoMP measurement set, to instruct the user equipment to estimate the downlink according to the CoMP measurement set The path loss is also used to instruct the user equipment to calculate the PH, PUCCH/PUSCH transmission power according to the uplink power control parameters corresponding to the CoMP measurement set; when the system is configured with carrier aggregation (CA), the downlink path loss refers to the association The information may be a primary serving cell (PCell), a secondary serving cell (SCell), or an uplink CoMP measurement set; when CA is not configured, the downlink path loss reference association information may be a PCell or an uplink CoMP measurement set.
此处需要说明的是，现有技术中在RRC信令中直接指示用户设备按照指定小区的参考信号CRS测量路损，而用户设备根据基站配置的服务小区发送CRS的信号功率-实际接收CRS的信号功率可以计算出下行路损；而本实施例中用户设备按照上行CoMP测量集合中多个CSI-RS的测量情况计算下行路损，配置信息包含多个CSI-RS或CRS的发射功率，用户设备可以基于上述多个CSI-RS或CRS的平均值或最小值，根据基站发送CRS或CSI-RS的功率-用户设备接收CSI-RS或CRS的功率计算下行路损，从而保证了下行路损估算的稳定性。What needs to be explained here is that in the prior art, the RRC signaling directly instructs the user equipment to measure the path loss according to the reference signal CRS of the designated cell, and the user equipment sends the signal power of the CRS according to the serving cell configured by the base station - the actual received CRS The signal power can calculate the downlink path loss; in this embodiment, the user equipment calculates the downlink path loss according to the measurement situation of multiple CSI-RSs in the uplink CoMP measurement set, and the configuration information includes the transmission power of multiple CSI-RSs or CRSs. The device can calculate the downlink path loss based on the average or minimum value of the above-mentioned multiple CSI-RS or CRS, and according to the power of the base station to send the CSI-RS or CSI-RS - the power of the user equipment to receive the CSI-RS or CRS, thereby ensuring the downlink path loss Estimated stability.
可选的，在用户设备获取到服务基站配置的上行协作多点CoMP测量集合后，所述用户设备可向服务基站发送无线资源控制连接重配置完成（RRCConnectionReconfigurationComplete）消息。Optionally, after the user equipment acquires the uplink coordinated multipoint CoMP measurement set configured by the serving base station, the user equipment may send a radio resource control connection reconfiguration complete (RRCConnectionReconfigurationComplete) message to the serving base station.

具体的，不论所述服务基站为所述用户设备配置的上行CoMP测量集合中所指示的是基于CSI-RS的RSRP测量或基于CRS的RSRP测量，所述用户设备均可以通过获取RSP与RSRP之差来估算所述下行路损；其中RSP为实际的参考信号发射功率，由服务基站通过RRC信令配置给用户设备。Specifically, regardless of whether the CSI-RS-based RSRP measurement or the CRS-based RSRP measurement indicated in the uplink CoMP measurement set configured by the serving base station for the user equipment, the user equipment can obtain the RSP and RSRP The difference is used to estimate the downlink path loss; where RSP is the actual reference signal transmission power, which is configured by the serving base station to the user equipment through RRC signaling.
此外，本实施例提供了另一种下行路损估算方式，但本领域普通技术人员理解并不局限于此：所述下行路损为所述上行CoMP测量集合中所有RP中最小下行路损；或，所有RP的下行路损的加权平均值，即不同的RP可以取值为不同的因子，所有因子的和为1；或，最小的n个RP的下行路损的平均值或加权平均值；其中n小于等于上行CoMP测量集中所有RP个数。In addition, this embodiment provides another downlink path loss estimation method, but those skilled in the art understand that it is not limited to this: the downlink path loss is the minimum downlink path loss among all RPs in the uplink CoMP measurement set; Or, the weighted average of the downlink path losses of all RPs, that is, different RPs can take different factors, and the sum of all factors is 1; or, the average or weighted average of the downlink path losses of the smallest n RPs ; where n is less than or equal to the number of all RPs in the uplink CoMP measurement set.
步骤130：所述用户设备根据所述下行路损生成功率余量报告PHR并将所述PHR上报给所述服务基站。Step 130: The user equipment generates a power headroom report PHR according to the downlink path loss and reports the PHR to the serving base station.
其中，在本实施例中采用周期型触发、基于下行路损变化触发或基于上行CoMP测量集合变化触发等方式，当然并不局限于此：具体的，当上行CoMP测量集合中增加和/或删除一个或多个RP的配置信息时，或者当上行CoMP测量集合的内容从基于CRS的RSRP测量重配置为基于CSI-RS的RSRP测量时，或当上行CoMP测量集合从基于CSI-RS的RSRP测量重配置为基于CRS的RSRP测量时，所述用户设备触发PHR过程。Among them, in this embodiment, periodic triggering, triggering based on downlink path loss changes, or triggering based on uplink CoMP measurement set changes, etc., are of course not limited to this: specifically, when adding and/or deleting configuration information of one or more RPs, or when the content of the uplink CoMP measurement set is reconfigured from CRS-based RSRP measurement to CSI-RS-based RSRP measurement, or when the uplink CoMP measurement set is changed from CSI-RS-based RSRP measurement to When reconfiguring to CRS-based RSRP measurement, the user equipment triggers a PHR procedure.
当所述用户设备触发了PHR过程后，用户设备计算PH、PCMAX，c、PUSCH发射功率、PUCCH发射功率，然后按照PHR的消息格式获取各参数并写入相应字段，生成PHR并报告给服务基站；其中，在本实施例中所述用户设备可以利用根据上行CoMP测量集合所估计的最小下行路损、根据最小下行路损所对应的RP的上行功率控制参数计算PH和PUCCH/PUSCH发射功率，或根据下行路损平均值或加权平均值、上行CoMP测量集合所对应的上行功率控制参数计算PH和PUCCH/PUSCH发射功率，或根据上行CoMP测量集合中每个RP所估计的下行路损、每个RP所对应的上行功率控制参数计算每个RP所对应的PH和PUCCH/PUSCH发射功率。When the user equipment triggers the PHR process, the user equipment calculates PH, PCMAX, c, PUSCH transmission power, and PUCCH transmission power, then obtains each parameter according to the message format of the PHR and writes it into the corresponding field, generates a PHR and reports it to the serving base station ; Wherein, in this embodiment, the user equipment can use the minimum downlink path loss estimated according to the uplink CoMP measurement set, and calculate the PH and PUCCH/PUSCH transmission power according to the uplink power control parameters of the RP corresponding to the minimum downlink path loss, Or calculate the transmit power of PH and PUCCH/PUSCH according to the average or weighted average of downlink path loss and the uplink power control parameters corresponding to the uplink CoMP measurement set, or calculate the downlink path loss and each RP estimated by each RP in the uplink CoMP measurement set The uplink power control parameters corresponding to each RP are used to calculate the PH and PUCCH/PUSCH transmit power corresponding to each RP.
此外，当所述用户设备配置了PH时，所述用户设备采用PHMACCE格式向所述服务基站报告PHR；当所述用户设备配置了extendedPH时，所述用户设备采用extendedPHMACCE向所述服务基站报告PHR；当所述用户设备配置了CA和extendedPH时，服务基站可以为主服务小区和至少1个辅服务小区分别配置上行CoMP测量集合，对于每个配置了上行CoMP测量集合的服务小区在extendedPH中包含根据该上行CoMP测量集合所计算的PH信息。In addition, when the user equipment is configured with PH, the user equipment uses the PHMACCE format to report PHR to the serving base station; when the user equipment is configured with extendedPH, the user equipment uses extendedPHMACCE to report PHR to the serving base station ; When the user equipment is configured with CA and extendedPH, the serving base station may configure an uplink CoMP measurement set for the primary serving cell and at least one secondary serving cell, and for each serving cell configured with an uplink CoMP measurement set, the extendedPH includes PH information calculated according to the uplink CoMP measurement set.
需要说明的是，本实施例中所述用户设备上报的PHR可以采用多种格式，下面仅以PHMACCE和extendedMACCE两种格式为例说明，但并不局限于此；It should be noted that the PHR reported by the user equipment in this embodiment can adopt multiple formats, and the following only uses the two formats of PHMACCE and extendedMACCE as examples, but is not limited thereto;

When the user equipment is configured with CA, the serving base station may configure a CoMP measurement set for the PCell and at least one SCell, and correspondingly indicate the CSI-RS for each serving cell in the extendedMACCE reported by the user equipment index or CoMP cell index; wherein, PCell and SCell are collectively referred to as a serving cell.
其中，如图2所示，所述PHMACCE占用三个字节的固定容量，包括一个字节的MAC子头和两个字节的PHRMACCE静荷；而MAC子头中“R”表示保留字段；“E”为扩展字段，指示是否还有后续的MAC子头及对应的媒体接入控制业务数据单元（MACSDU）；LCID为逻辑信道标识，代表了该MACCE的类型；MACCE静荷中“R”表示保留字段，PH表示功率余量级别，取值0～63；静荷中的D0～7表示参考信号索引，代表上行CoMP测量中的CSI-RS索引或CoMP小区索引。Wherein, as shown in Figure 2, described PHMACCE occupies the fixed capacity of three bytes, comprises the MAC subhead of one byte and the PHRMACCE static load of two bytes; And " R " represents reserved field in the MAC subhead; "E" is an extension field, indicating whether there is a subsequent MAC subheader and the corresponding media access control service data unit (MACSDU); LCID is a logical channel identifier, representing the type of the MACCE; "R" in the MACCE payload Represents a reserved field, PH represents a power headroom level, and takes a value of 0 to 63; D0 to 7 in the payload represent a reference signal index, representing a CSI-RS index or a CoMP cell index in uplink CoMP measurement.
如图3所示，ExtendedPHMACCE格式为可变长度的，包括一个两字节的MAC子头和可变长度的extendedPHRMACCE静荷，与是否配置了PUCCH和PUSCH同时发送、发送PHR时处于激活状态的SCell数目、各激活的SCell是否分配有上行资源等因素有关；其中，MAC子头中“R/E/LCID”的含义同PHR的MAC子头；“F”表示“L”字段为7bit还是15bit；“L”表示MAC静荷的长度；MACCE静荷中“R/PH”的含义同PHMACCE静荷；当配置了PUCCH和PUSCH同时发送时包含还包含类型2PH，否则仅包含类型1PH；“C1～C7”表示SCell索引所对应的PH是否存在，只有处于激活状态的SCell才有对应的PH；D0～7表示参考信号索引，代表对应的服务小区所配置的上行CoMP测量中的CSI-RS索引或CoMP小区索引；“P”表示用户设备是否进行了功率回退；“V”表示计算PH时是针对真实的上行发送还是虚拟PH，前者表示发送PHR时该SCell上分配有上行资源，后者表示该SCell上没有上行资源，而是使用了参考格式；当“V”为0是对应的服务小区所配置的最大用户设备输出功率PCMAX字段不出现。As shown in Figure 3, the ExtendedPHMACCE format is variable-length, including a two-byte MAC subheader and variable-length extendedPHRMACCE payload, and whether PUCCH and PUSCH are configured to be sent at the same time, and the SCell that is active when sending PHR The number and whether each activated SCell is allocated uplink resources are related to factors such as; Among them, the meaning of "R/E/LCID" in the MAC subheader is the same as that of the PHR MAC subheader; "F" indicates whether the "L" field is 7bit or 15bit; "L" indicates the length of the MAC static load; the meaning of "R/PH" in the MACCE static load is the same as that of the PHMACCE static load; when PUCCH and PUSCH are configured to be sent at the same time, it also includes type 2PH, otherwise only type 1PH is included; "C1～ C7" indicates whether the PH corresponding to the SCell index exists, and only the activated SCell has the corresponding PH; D0~7 indicate the reference signal index, which represents the CSI-RS index in the uplink CoMP measurement configured by the corresponding serving cell or CoMP cell index; "P" indicates whether the user equipment has performed power back-off; "V" indicates whether the calculation of PH is for real uplink transmission or virtual PH. The former indicates that the SCell has allocated uplink resources when sending PHR, and the latter indicates There is no uplink resource on the SCell, but a reference format is used; when "V" is 0, the maximum user equipment output power PCMAX field configured by the corresponding serving cell does not appear.
其二、当采用所述extendedPHMACCE上报所述PHR时，在所述extendedPHMACCE中也可以包含根据每个RP的下行路损所计算的PH和/或对应的PCMAX；其中，当配置了CA时，服务基站为PCell和至少1个SCell分别配置CoMP测量集，而在extendedMACCE中针对每个服务小区分别包含根据其上行CoMP测量集中每个RP的下行路损所计算的PH和/或对应的PCMAX；其与采用PHMACCE的不同之处在于PCell和每个激活的服务小区均可以包含多个PH，当CSI-RS索引或CoMP小区索引D0～D7对应bit取值为1时，则包含其PH；每个激活的服务小区的PCMAX包含1个，也可以包含多个，在此不再赘述。Second, when the extendedPHMACCE is used to report the PHR, the extendedPHMACCE may also include the PH calculated according to the downlink path loss of each RP and/or the corresponding PCMAX; wherein, when CA is configured, the service The base station configures the CoMP measurement set for the PCell and at least one SCell respectively, and the extendedMACCE includes, for each serving cell, the PH and/or the corresponding PCMAX calculated according to the downlink path loss of each RP in the uplink CoMP measurement set; The difference from using PHMACCE is that PCell and each activated serving cell can contain multiple PHs. When the corresponding bit value of CSI-RS index or CoMP cell index D0~D7 is 1, its PH is included; each The PCMAX of the activated serving cell includes one or more than one, which will not be repeated here.

除此之外，当所述服务基站为所述用户设备配置了上行功率控制参数后，该上行功率控制参数包括以下至少一种：标称PUCCH基准发射功率（p0-NominalPUCCH）、用户设备特定的PUCCH基准发射功率（p0-用户设备-PUCCH）、标称PUSCH基准发射功率（p0-NominalPUSCH）、用户设备特定的PUSCH基准发射功率（p0-用户设备-PUSCH）、下行路损补偿因子（alpha）等信息；当然并不局限于此，本实施例在此不再赘述。值得注意的是，本实施例的方法还可以针对每个上行CoMP测量集合配置与其对应的上行功率控制参数，也可以针对所述上行CoMP测量集合中的每个CSI-RS配置信息或CoMP小区配置信息分别配置与其对应的上行功率控制参数；上行功率控制参数配置信息可以和所关联的上行CoMP测量集配置信息包含在不同的RRC信元中。In addition, when the serving base station configures uplink power control parameters for the user equipment, the uplink power control parameters include at least one of the following: nominal PUCCH reference transmit power (p0-NominalPUCCH), user equipment specific PUCCH reference transmit power (p0-user equipment-PUCCH), nominal PUSCH reference transmit power (p0-NominalPUSCH), user equipment-specific PUSCH reference transmit power (p0-user equipment-PUSCH), downlink path loss compensation factor (alpha) and other information; of course, it is not limited to this, and this embodiment will not be repeated here. It is worth noting that the method of this embodiment can also configure the corresponding uplink power control parameters for each uplink CoMP measurement set, or configure each CSI-RS configuration information or CoMP cell in the uplink CoMP measurement set The information configures corresponding uplink power control parameters; the uplink power control parameter configuration information and the associated uplink CoMP measurement set configuration information may be included in different RRC information elements.
同理，当所述服务基站为所述用户设备配置了下行路损参考关联信息后，该下行路损参考关联信息指示所述用户设备在估算下行路损、计算PH、PUCCH/PUSCH发射功率、探测参考信号（SRS）发射功率时所使用的关联信息；其中，所述下行路损参考关联信息可以与所述上行CoMP测量集合相关联，用以指示所述用户设备按照CoMP测量集合估算下行路损，同时也用以指示所述用户设备按照CoMP测量集合对应的上行功率控制参数计算PH、PUCCH/PUSCH发射功率；当系统在配置了载波聚合（CA）时，所述下行路损参考关联信息可以为主服务小区（PCell）、辅服务小区（SCell）或上行CoMP测量集合；在未配置CA时，所述下行路损参考关联信息可以为PCell或上行CoMP测量集合。Similarly, when the serving base station configures downlink path loss reference association information for the user equipment, the downlink path loss reference association information instructs the user equipment to estimate the downlink path loss, calculate PH, PUCCH/PUSCH transmission power, Association information used when sounding reference signal (SRS) transmit power; wherein, the downlink path loss reference association information may be associated with the uplink CoMP measurement set, to instruct the user equipment to estimate the downlink path according to the CoMP measurement set It is also used to instruct the user equipment to calculate PH, PUCCH/PUSCH transmission power according to the uplink power control parameters corresponding to the CoMP measurement set; when the system is configured with carrier aggregation (CA), the downlink path loss refers to the associated information It can be a primary serving cell (PCell), a secondary serving cell (SCell), or an uplink CoMP measurement set; when CA is not configured, the downlink path loss reference association information can be a PCell or an uplink CoMP measurement set.
此处需要说明的是，现有技术中在RRC信令中直接指示用户设备按照指定小区的参考信号CRS测量路损，而用户设备根据基站配置的服务小区发送CRS的信号功率-实际接收CRS的信号功率可以计算出下行路损；而本实施例中通过指示用户设备按照上行CoMP测量集合中多个CSI-RS的测量情况计算下行路损，配置信息包含多个CSI-RS或CRS的发射功率，而用户设备可以基于上述多个CSI-RS或CRS的平均值或最小值，根据基站发送CRS或CSI-RS的功率-用户设备接收CSI-RS或CRS的功率计算下行路损，从而保证了下行路损估算的稳定性。What needs to be explained here is that in the prior art, the RRC signaling directly instructs the user equipment to measure the path loss according to the reference signal CRS of the designated cell, and the user equipment sends the signal power of the CRS according to the serving cell configured by the base station - the actual received CRS The signal power can calculate the downlink path loss; in this embodiment, the user equipment is instructed to calculate the downlink path loss according to the measurement conditions of multiple CSI-RSs in the uplink CoMP measurement set, and the configuration information includes the transmission power of multiple CSI-RSs or CRSs , and the user equipment can calculate the downlink path loss based on the average or minimum value of the above-mentioned multiple CSI-RS or CRS, according to the power of the base station to send the CSI-RS or CSI-RS - the power of the user equipment to receive the CSI-RS or CRS, thus ensuring Stability of downlink path loss estimation.

具体的，不论所述服务基站为所述用户设备配置的上行CoMP测量集合中所指示的是基于CSI-RS的RSRP测量或基于CRS的RSRP测量，所述用户设备都通过获取RSP与RSRP之差来估算所述下行路损；其中RSP为实际的参考信号发射功率，由服务基站通过RRC信令配置给用户设备。Specifically, regardless of whether the uplink CoMP measurement set configured by the serving base station for the user equipment is CSI-RS-based RSRP measurement or CRS-based RSRP measurement, the user equipment obtains the difference between RSP and RSRP to estimate the downlink path loss; where RSP is the actual reference signal transmission power, which is configured by the serving base station to the user equipment through RRC signaling.
此外，当所述用户设备配置了PH时，所述用户设备采用PHMACCE格式向所述服务基站报告PHR；当所述用户设备配置了extendedPH时，所述用户设备采用extendedPHMACCE向所述服务基站报告PHR；当所述用户设备配置了CA和extendedPH时，服务基站可以为主服务小区和至少1个辅服务小区分别配置上行CoMP测量集合，对于每个配置了上行CoMP测量集合的服务小区在extendedPH中包含根据该上行CoMP测量集合所计算的PH信息。In addition, when the user equipment is configured with PH, the user equipment uses the PHMACCE format to report PHR to the serving base station; when the user equipment is configured with extendedPH, the user equipment uses extendedPHMACCE to report PHR to the serving base station ; When the user equipment is configured with CA and extendedPH, the serving base station may configure an uplink CoMP measurement set for the primary serving cell and at least one secondary serving cell, and for each serving cell configured with an uplink CoMP measurement set, the extendedPH includes PH information calculated according to the uplink CoMP measurement set.
此外，本实施例还可包括步骤230：当周期性测量报告定时器超时，或者当上行CoMP测量集中某个或多个RP的RSRP小于门限X或下行路损大于门限Y时，或者当估算的下行路损与最小RP的下行路损的差值超过门限Z时，所述服务基站接收所述用户设备上报的测量报告，并根据所述测量报告更新所述上行CoMP测量集合；其中，所述门限X、Y和Z为预设的门限值。In addition, this embodiment may further include step 230: when the periodic measurement report timer expires, or when the RSRP of one or more RPs in the uplink CoMP measurement set is less than the threshold X or the downlink path loss is greater than the threshold Y, or when the estimated When the difference between the downlink path loss and the downlink path loss of the smallest RP exceeds the threshold Z, the serving base station receives the measurement report reported by the user equipment, and updates the uplink CoMP measurement set according to the measurement report; wherein, the Thresholds X, Y and Z are preset threshold values.
其中，本实施例中所述服务基站接收到的用户设备上报的测量报告还可包括：上行CoMP测量集合中下行路损最小的RP对应的CSI-RS索引或PCI（PhysicalCellIdentification，物理小区标识）；或上行CoMP测量集合中下行路损最小的多个RP对应的CSI-RS索引或PCI；或者上行CoMP测量集合中RSRP小于门限x或下行路损大于门限x的某个或多个RP对应的CSI-RS索引或PCI；此外，所述测量报告还可包括所述RP对应的CSI-RS或PCI对应的RSRP或下行路损值等；但并不局限于此。Wherein, the measurement report reported by the user equipment received by the serving base station in this embodiment may further include: a CSI-RS index or PCI (PhysicalCellIdentification, physical cell identification) corresponding to the RP with the smallest downlink path loss in the uplink CoMP measurement set; Or the CSI-RS index or PCI corresponding to multiple RPs with the smallest downlink path loss in the uplink CoMP measurement set; or the CSI corresponding to one or more RPs in the uplink CoMP measurement set whose RSRP is smaller than the threshold x or the downlink path loss is greater than the threshold x - RS index or PCI; in addition, the measurement report may also include the CSI-RS corresponding to the RP or the RSRP or downlink path loss value corresponding to the PCI; but it is not limited thereto.
相应的，当所述服务基站接收到所述用户设备上报的测量报告后，还可根据所述测量报告更新所述上行CoMP测量集合，并为所述用户设备配置所述更新的上行CoMP测量集合；所述用户设备在接收到所述更新后的上行CoMP测量集合后向服务基站发送无线资源控制连接重配置完成消息。其中，所述服务基站更新上行CoMP测量集合的操作具体可通过以下方式实现，但并不局限于此：从所述上行CoMP测量集合中删除RSRP小于第一预设门限值或下行路损大于第二预设门限值对应的RP，或者在所述上行CoMP测量集合中增加新RP配置信息。Correspondingly, after the serving base station receives the measurement report reported by the user equipment, it may also update the uplink CoMP measurement set according to the measurement report, and configure the updated uplink CoMP measurement set for the user equipment ; after receiving the updated uplink CoMP measurement set, the user equipment sends a radio resource control connection reconfiguration complete message to the serving base station.

具体的，当所述测量报告显示所述用户设备因位置改变等原因导致其无线条件发生变化时，所述服务基站已配置上行CoMP测量集合中的个别RP可能不再适合参与用户设备的上行协作通信，此时需要所述服务基站将这些RP删除，或者增加新的RP；例如所述服务基站从上行CoMP测量集合中删除RSRP小于门限x或下行路损大于门限x对应的RP，或者所述服务基站根据其他测量结果，如SRS或无线资源管理（RRM）测量增加新的RP配置信息到所述上行CoMP测量集合中；当然还可以有其他方式，本实施例在此不再赘述。Specifically, when the measurement report shows that the radio condition of the user equipment changes due to reasons such as a change in location, individual RPs in the uplink CoMP measurement set configured by the serving base station may no longer be suitable for participating in the uplink coordination of the user equipment Communication, at this time, the serving base station needs to delete these RPs, or add a new RP; for example, the serving base station deletes the RP corresponding to the RSRP less than the threshold x or the downlink path loss is greater than the threshold x from the uplink CoMP measurement set, or the The serving base station adds new RP configuration information to the uplink CoMP measurement set according to other measurement results, such as SRS or radio resource management (RRM) measurement; of course, there are other ways, which will not be repeated in this embodiment.
