210、终端设备接收网络设备发送的基于端口的累积发射功率控制信令，所述基于端口的累积发射功率控制信令为若所述网络设备接收的所述终端设备的至少两个发射天线端口中两个发射天线端口的接收功率之间的功率差值大于或等于预先设置的开始调整阈值发送。

本发明所提供的技术方案，可以适用于物理上行共享信道(Physical Uplink Shared Channel，PUSCH)传输，或者还可以适用于其他上行信道传输，本实施例对此不进行特别限定。
目前，物理上行共享信道(Physical Uplink Shared Channel，PUSCH)传输的发送功率可以通过如下公式计算：
Figure PCTCN2018123449-appb-000001
其中，i是一次PUSCH传输的索引，j是开环功率控制参数的索引(包括目标功率P O_PUSCH,b,f,c(j)和路损因子α b,f,c(j))，f b,f,c(i,l)是针对终端设备整体的闭环发射功率控制调整因子，其中l是闭环发射功率控制进程的索引。
终端设备采用多发射天线发射上行信号时，可能会因为各个发射天线自身的损耗差异及人体遮挡等因素，导致在网络设备端接收的上行信号的信号强度存在较大差异，导致上行MIMO的传输能力下降。
由于上述针对终端设备整体进行发射功率控制的方法，没有考虑到不同发射天线端口的损耗等因素的可能会有所不同，因此，网络设备所接收到的各个发射天线端口所发射的上行信号的接收功率会存在较大差异，这样，会导致上行多天线传输能力的下降。
本发明所提供的技术方案，通过在上行传输的发射功率控制中引入基于端口的发射功率控制，及其相应的信令和调整参数，使得网络设备可以调整终端设备不同发射天线端口的发射功率，最终在网络设备端接收到的各发射天线端口之间的信号强度保持相对平衡状态，能够有效增加上行吞吐量。
针对现有的这种针对终端设备整体进行发射功率控制的方法，本发明的主要思想为：在网络设备接收的终端设备的至少两个发射天线端口中任意两个发射天线端口的接收功率之间的功率差值大于或等于预先设置的开始调整阈值时，则可以由网络设备直接对终端设备不同发射天线端口的发射功率进行调整，以得到需要的发射功率，从而实现了终端设备的各个发射天线端口的发射功率在接收端达到平衡状态，能够进一步提高上行多天线传输能力。
本发明中，可以在网络设备向终端设备所发送的用于上行传输的发射功率控制(Transmit Power Control，TPC)的相关信令中，增加基于端口的累积发射功率控制(TPC-Accumulation-Port)信令。所述基于端口的累积发射功率控制(TPC-Accumulation-Port)信令，用于指示终端设备对该终端设备的指定发射天线端口的发射功率进行调整。
相应地，还可以在网络设备向终端设备所发送的发射功率控制参数中，增加基于指定端口的闭环发射功率控制调整因子，用以指示终端设备对该指定端口采用对应的闭环发射功率控制调整因子，来进行基于端口的发射功率调整。
可选地，在本实施例的一个可能的实现方式中，在210中，若所述网络设备接收的所述终端设备的至少两个发射天线端口中两个发射天线端口的接收功率之间的功率差值大于或等于预先设置的开始调整阈值，例如，6dB等，所述终端设备具体可以接收所述网络设备发送的用于上行传输的TPC的相关信令，在该上行的TPC的相关信令中可以激活TPC-Accumulation-Port信令。
此时，在该上行的TPC的相关信令中可以禁用原有的累积发射功率控制(TPC-Accumulation)信令。
这样，终端设备在接收到该上行的TPC的相关信令时，则可以根据该TPC的相关信令中所激活的TPC-Accumulation-Port信令，执行后续基于端口的发射功率调整的相关操作。
可选地，在本实施例的一个可能的实现方式中，所述终端设备执行210和220的顺序不固定，可以先执行210，再执行220，或者还可以先执行220，再执行210，或者也可以同时执行210和220，本实施例对此不进行特别限定。
可选地，在本实施例的一个可能的实现方式中，在220中，所述终端设备具体可以接收所述网络设备发送的所述至少一个发射天线端口中需要调整的发射天线端口的闭环发射功率控制调整因子即f b,f,c,m(i,l)。也就是说，所述网络设备将不再向所述终端设备发送不需要调整的发射天线端口的闭环发射功率控制调整因子。这样，能够节省传输的信令开销。
可选地，在本实施例的一个可能的实现方式中，在220中，所述终端设备具体可以接收所述网络设备发送的所述至少一个发射天线端口中每个发射天线端口的闭环发射功率控制调整因子。也就是说，所述网络设备可以将向所述终端设备发送的不需要调整的发射天线端口的闭环发射功率控制调整因子设置为0。
可选地，在本实施例的一个可能的实现方式中，在220中，所述终端数具体可以接收所述网络设备通过高层信令，或者调度上行传输的下行控制信息(Downlink Control Information，DCI)，发送的所述至少一个发射天线端口的闭环发射功率控制调整因子。
例如，所述高层信令可以是无线资源控制(Radio Resource Control，RRC)消息，具体可以通过RRC消息中的信息元素(Information Element，IE)携带所述至少一个发射天线端口的闭环发射功率控制调整因子，所述RRC消息可以为现有技术中的RRC消息，例如，RRC连接重配置(RRC CONNECTION RECONFIGURATION)消息等，本实施例对此不进行限定，通过对已有的RRC消息的IE进行扩展携带所述至少一个发射天线端口的闭环发射功率控制调整因子，或者所述RRC消息也可以为不同于现有技术中已有的RRC消息。
或者，再例如，所述高层信令可以是媒体访问控制(Media Access Control，MAC)控制元素(Control Element，CE)消息，具体还可以通过增加新的MAC CE消息携带所述至少一个发射天线端口的闭环发射功率控制调整因子。
可选地，在本实施例的一个可能的实现方式中，在220之前，所述网络设备还可以进一步确定需要调整的发射天线端口。这样，网络设备则可以根据需要调整的发射天线端口，获得每个发射天线端口的闭环发射功率控制调整因子。
在该实现方式中，所述网络设备可以采用各种发射功率控制策略，确定需要调整的发射天线端口，以使得所述网络设备接收的调整之后的发射天线端口的接收功率之间的差值小于预先设置的结束调整阈值。
其中，所述结束调整阈值可以小于所述开始调整阈值，或者还可以等于所述开始调 整阈值，本实施例对此不进行特别限定。
假设终端设备的两个发射天线端口分别为Port1和Port2；终端设备在Port1和Port2的发射功率分别为P 1和P 2，P1+P2≤Pue，其中，Pue为终端设备的最大发射功率能力，P 1与P 2之和需要不超过该Pue；网络设备接收的Port1和Port2的接收功率分别为R 1和R 2，R 2>R 1。
此时，网络设备可以调整R 2将其功率降低，也可以调整R 1将其功率增加，或者同时调整R 2将其功率降低，以及调整R 1将其功率增加，本实施例对此不进行特别限定。
那么，在该实现方式中，所述需要调整的发射天线端口，可以包括但不限于下列发射天线端口中的至少一项：
所述终端设备的至少两个发射天线端口中接收功率的功率差值大于或等于所述开始调整阈值的任意两个发射天线端口或者其中的一个发射天线端口；
所述终端设备的至少两个发射天线端口中接收功率的功率差值最大的两个发射天线端口或者其中的一个发射天线端口；以及
所述终端设备的至少两个发射天线端口中全部发射天线端口。
可选地，在本实施例的一个可能的实现方式中，在230中，所述终端设备具体可以利用所述至少一个发射天线端口的闭环发射功率控制调整因子，对所述至少一个发射天线端口中需要调整的发射天线端口的发射功率进行调整，以使得所述网络设备接收的调整之后的发射天线端口的接收功率之间的差值小于预先设置的结束调整阈值。
为使得本发明实施例提供的方法更加清楚，下面将以两个发射天线端口的终端设备的PUSCH传输作为举例。假设终端设备的两个发射天线端口分别为Port1和Port2，终端设备在Port1和Port2的发射功率分别为P 1和P 2，基站接收的Port1和Port2的接收功率分别为R 1和R 2。
基站通过对比R 1和R 2的功率强度，若二者之间的功率差值大于或等于预先设置的开始调整阈值例如，6dB，基站则可以启动基于端口的发射功率调制机制。
此时，PUSCH的上行传输的发射功率控制中，TPC-Accumulation-Port信令被激活。基站向终端设备发送Port1的闭环发射功率控制调整因子和Port2的闭环发射功率控制调整因子，用以分别控制Port1的发射功率和Port2的发射功率进行调整，直到R 1和R 2二者之间的功率差值小于预先设置的结束调整阈值例如，3dB为止。
这样，基站通过调整终端设备不同发射天线端口的发射功率强度，最终在基站接收到的各发射天线端口之间的信号强度保持相对平衡状态，从而增加了上行吞吐量。
本实施例中，通过终端设备接收网络设备发送的基于端口的累积发射功率控制信令，进而由所述终端设备接收所述网络设备发送的所述至少两个发射天线端口中至少一个发射天线端口的闭环发射功率控制调整因子，使得所述终端设备能够利用所述至少一个发射天线端口的闭环发射功率控制调整因子，进行基于端口的发射功率调整，从而实现了终端设备的各个发射天线端口的发射功率在接收端达到平衡状态，能够进一步提高上行多天线传输能力。
图3是本申请实施例提供的另一种上行传输的功率控制方法300的示意性图。
310、若网络设备接收的终端设备的至少两个发射天线端口中两个发射天线端口的接收功率之间的功率差值大于或等于预先设置的开始调整阈值，所述网络设备向所述终端设备发送基于端口的累积发射功率控制信令。
320、所述网络设备向所述终端设备发送所述至少两个发射天线端口中至少一个发射天线端口的闭环发射功率控制调整因子，以供所述终端设备利用所述至少一个发射天线端口的闭环发射功率控制调整因子，进行基于端口的发射功率调整。
本发明所提供的技术方案，可以适用于物理上行共享信道(Physical Uplink Shared Channel，PUSCH)传输，或者还可以适用于其他上行信道传输，本实施例对此不进行特别限定。
目前，物理上行共享信道(Physical Uplink Shared Channel，PUSCH)传输的发送功率可以通过如下公式计算：
Figure PCTCN2018123449-appb-000002
其中，i是一次PUSCH传输的索引，j是开环功率控制参数的索引(包括目标功率P O_PUSCH,b,f,c(j)和路损因子α b,f,c(j))，f b,f,c(i,l)是针对终端设备整体的闭环发射功率控制调整因子，其中l是闭环发射功率控制进程的索引。
终端设备采用多发射天线发射上行信号时，可能会因为各个发射天线自身的损耗差异及人体遮挡等因素，导致在网络设备端接收的上行信号的信号强度存在较大差异，导致上行MIMO的传输能力下降。
由于上述针对终端设备整体进行发射功率控制的方法，没有考虑到不同发射天线端口的损耗等因素的可能会有所不同，因此，网络设备所接收到的各个发射天线端口所发射的上行信号的接收功率会存在较大差异，这样，会导致上行多天线传输能力的下降。
本发明所提供的技术方案，通过在上行传输的发射功率控制中引入基于端口的发射功率控制，及其相应的信令和调整参数，使得网络设备可以调整终端设备不同发射天线端口的发射功率，最终在网络设备端接收到的各发射天线端口之间的信号强度保持相对平衡状态，能够有效增加上行吞吐量。
针对现有的这种针对终端设备整体进行发射功率控制的方法，本发明的主要思想为：在网络设备接收的终端设备的至少两个发射天线端口中任意两个发射天线端口的接收功率之间的功率差值大于或等于预先设置的开始调整阈值时，则可以由网络设备直接对终端设备不同发射天线端口的发射功率进行调整，以得到需要的发射功率，从而实现了终端设备的各个发射天线端口的发射功率在接收端达到平衡状态，能够进一步提高上行多天线传输能力。
本发明中，可以在网络设备向终端设备所发送的用于上行传输的发射功率控制(Transmit Power Control，TPC)的相关信令中，增加基于端口的累积发射功率控制(TPC-Accumulation-Port)信令。所述基于端口的累积发射功率控制(TPC-Accumulation-Port)信令，用于指示终端设备对该终端设备的指定发射天线端口的发射功率进行调整。
相应地，还可以在网络设备向终端设备所发送的发射功率控制参数中，增加基于指定端口的闭环发射功率控制调整因子，用以指示终端设备对该指定端口采用对应的闭环发射功率控制调整因子，来进行基于端口的发射功率调整。
可选地，在本实施例的一个可能的实现方式中，在310中，若所述网络设备接收的所述终端设备的至少两个发射天线端口中两个发射天线端口的接收功率之间的功率差值大于或等于预先设置的开始调整阈值，例如，6dB等，所述网络设备具体可以向所述终端设备发送用于上行传输的TPC的相关信令，在该上行的TPC的相关信令中可以激活TPC-Accumulation-Port信令。
此时，在该上行的TPC的相关信令中可以禁用原有的累积发射功率控制(TPC-Accumulation)信令。
这样，终端设备在接收到该上行的TPC的相关信令时，则可以根据该TPC的相关信令中所激活的TPC-Accumulation-Port信令，执行后续基于端口的发射功率调整的相关操作。
可选地，在本实施例的一个可能的实现方式中，所述网络设备执行310和320的顺序不固定，可以先执行310，再执行320，或者还可以先执行320，再执行310，或 者也可以同时执行310和320，本实施例对此不进行特别限定。
可选地，在本实施例的一个可能的实现方式中，在320中，所述网络设备具体可以向所述终端设备发送所述至少一个发射天线端口中需要调整的发射天线端口的闭环发射功率控制调整因子即f b,f,c,m(i,l)。也就是说，所述网络设备将不再向所述终端设备发送不需要调整的发射天线端口的闭环发射功率控制调整因子。这样，能够节省传输的信令开销。
可选地，在本实施例的一个可能的实现方式中，在320中，所述网络设备具体可以向所述终端设备发送所述至少一个发射天线端口中每个发射天线端口的闭环发射功率控制调整因子。也就是说，所述网络设备可以将向所述终端设备发送的不需要调整的发射天线端口的闭环发射功率控制调整因子设置为0。
可选地，在本实施例的一个可能的实现方式中，在320中，所述网络设备具体可以通过高层信令，或者调度上行传输的下行控制信息(Downlink Control Information，DCI)，向所述终端数发送所述至少一个发射天线端口的闭环发射功率控制调整因子。
例如，所述高层信令可以是无线资源控制(Radio Resource Control，RRC)消息，具体可以通过RRC消息中的信息元素(Information Element，IE)携带所述至少一个发射天线端口的闭环发射功率控制调整因子，所述RRC消息可以为现有技术中的RRC消息，例如，RRC连接重配置(RRC CONNECTION RECONFIGURATION)消息等，本实施例对此不进行限定，通过对已有的RRC消息的IE进行扩展携带所述至少一个发射天线端口的闭环发射功率控制调整因子，或者所述RRC消息也可以为不同于现有技术中已有的RRC消息。
或者，再例如，所述高层信令可以是媒体访问控制(Media Access Control，MAC)控制元素(Control Element，CE)消息，具体还可以通过增加新的MAC CE消息携带所述至少一个发射天线端口的闭环发射功率控制调整因子。
可选地，在本实施例的一个可能的实现方式中，在320之前，所述网络设备还可以进一步确定需要调整的发射天线端口。这样，网络设备则可以根据需要调整的发射天线端口，获得每个发射天线端口的闭环发射功率控制调整因子。
在该实现方式中，所述网络设备可以采用各种发射功率控制策略，确定需要调整的发射天线端口，以使得所述网络设备接收的调整之后的发射天线端口的接收功率之间的差值小于预先设置的结束调整阈值。其中，所述结束调整阈值小于或等于所述开始调整阈值。
假设终端设备的两个发射天线端口分别为Port1和Port2；终端设备在Port1和Port2的发射功率分别为P 1和P 2，P1+P2≤Pue，其中，Pue为终端设备的最大发射功率能力，P 1与P 2之和需要不超过该Pue；网络设备接收的Port1和Port2的接收功率分别为R 1和R 2，R 2>R 1。
此时，网络设备可以调整R 2将其功率降低，也可以调整R 1将其功率增加，或者同时调整R 2将其功率降低，以及调整R 1将其功率增加，本实施例对此不进行特别限定。
那么，在该实现方式中，所述需要调整的发射天线端口，可以包括但不限于下列发射天线端口中的至少一项：
所述终端设备的至少两个发射天线端口中接收功率的功率差值大于或等于所述开始调整阈值的任意两个发射天线端口或者其中的一个发射天线端口；
所述终端设备的至少两个发射天线端口中接收功率的功率差值最大的两个发射天线端口或者其中的一个发射天线端口；以及
所述终端设备的至少两个发射天线端口中全部发射天线端口。
所述终端设备接收所述至少一个发射天线端口的闭环发射功率控制调整因子之后，则可以利用所述至少一个发射天线端口的闭环发射功率控制调整因子，进行基于端口的 发射功率调整。
具体来说，所述终端设备具体可以利用所述至少一个发射天线端口的闭环发射功率控制调整因子，对所述至少一个发射天线端口中需要调整的发射天线端口的发射功率进行调整，以使得所述网络设备接收的调整之后的发射天线端口的接收功率之间的差值小于预先设置的结束调整阈值。
其中，所述结束调整阈值可以小于所述开始调整阈值，或者还可以等于所述开始调整阈值，本实施例对此不进行特别限定。
为使得本发明实施例提供的方法更加清楚，下面将以两个发射天线端口的终端设备的PUSCH传输作为举例。假设终端设备的两个发射天线端口分别为Port1和Port2，终端设备在Port1和Port2的发射功率分别为P 1和P 2，基站接收的Port1和Port2的接收功率分别为R 1和R 2。
基站通过对比R 1和R 2的功率强度，若二者之间的功率差值大于或等于预先设置的开始调整阈值例如，6dB，基站则可以启动基于端口的发射功率调制机制。
此时，PUSCH的上行传输的发射功率控制中，TPC-Accumulation-Port信令被激活。基站向终端设备发送Port1的闭环发射功率控制调整因子和Port2的闭环发射功率控制调整因子，用以分别控制Port1的发射功率和Port2的发射功率进行调整，直到R 1和R 2二者之间的功率差值小于预先设置的结束调整阈值例如，3dB为止。
这样，基站通过调整终端设备不同发射天线端口的发射功率强度，最终在基站接收到的各发射天线端口之间的信号强度保持相对平衡状态，从而增加了上行吞吐量。
本实施例中，若网络设备接收的终端设备的至少两个发射天线端口中两个发射天线端口的接收功率之间的功率差值大于或等于预先设置的开始调整阈值，通过所述网络设备向所述终端设备发送基于端口的累积发射功率控制信令，使得所述网络设备能够向所述终端设备发送所述至少两个发射天线端口中至少一个发射天线端口的闭环发射功率控制调整因子，以供所述终端设备利用所述至少一个发射天线端口的闭环发射功率控制调整因子，进行基于端口的发射功率调整，从而实现了终端设备的各个发射天线端口的发射功率在接收端达到平衡状态，能够进一步提高上行多天线传输能力。
