具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述。
应理解，本申请实施例的技术方案可以应用于各种通信系统，例如：全 球移动通讯(Global System of Mobile communication，GSM)系统、码分多址(Code Division Multiple Access，CDMA)系统、宽带码分多址(Wideband Code Division Multiple Access，WCDMA)系统、通用分组无线业务(General Packet Radio Service，GPRS)、长期演进LTE系统、LTE频分双工(Frequency Division Duplex，FDD)系统、LTE时分双工(Time Division Duplex，TDD)、通用移动通信系统(Universal Mobile Telecommunication System，UMTS)、全球互联微波接入(Worldwide Interoperability for Microwave Access，WiMAX)通信系统、新无线(New Radio，NR)或未来的5G系统等。
特别地，本申请实施例的技术方案可以应用于各种基于非正交多址接入技术的通信系统，例如稀疏码多址接入(Sparse Code Multiple Access，SCMA)系统、低密度签名(Low Density Signature，LDS)系统等，当然SCMA系统和LDS系统在通信领域也可以被称为其他名称；进一步地，本申请实施例的技术方案可以应用于采用非正交多址接入技术的多载波传输系统，例如采用非正交多址接入技术正交频分复用(Orthogonal Frequency Division Multiplexing，OFDM)、滤波器组多载波(Filter Bank Multi-Carrier，FBMC)、通用频分复用(Generalized Frequency Division Multiplexing，GFDM)、滤波正交频分复用(Filtered-OFDM，F-OFDM)系统等。
本申请实施例中的终端设备可以指用户设备(User Equipment，UE)、接入终端、用户单元、用户站、移动站、移动台、远方站、远程终端、移动设备、用户终端、终端、无线通信设备、用户代理或用户装置。接入终端可以是蜂窝电话、无绳电话、会话启动协议(Session Initiation Protocol，SIP)电话、无线本地环路(Wireless Local Loop，WLL)站、个人数字处理(Personal Digital Assistant，PDA)、具有无线通信功能的手持设备、计算设备或连接到无线调制解调器的其它处理设备、车载设备、可穿戴设备，未来5G网络中的终端设备或者未来演进的公用陆地移动通信网络(Public Land Mobile Network，PLMN)中的终端设备等，本申请实施例并不限定。
本申请实施例中的网络设备可以是用于与终端设备通信的设备，该网络设备可以是GSM或CDMA中的基站(Base Transceiver Station，BTS)，也可以是WCDMA系统中的基站(NodeB，NB)，还可以是LTE系统中的演进型基站(Evolutional NodeB，eNB或eNodeB)，还可以是云无线接入网络(Cloud Radio Access Network，CRAN)场景下的无线控制器，或者该网络 设备可以为中继站、接入点、车载设备、可穿戴设备以及未来5G网络中的网络设备或者未来演进的PLMN网络中的网络设备等，本申请实施例并不限定。
图1是本申请实施例一个应用场景的示意图。图1中的通信系统可以包括终端设备10和网络设备20。网络设备20用于为终端设备10提供通信服务并接入核心网，终端设备10通过搜索网络设备20发送的同步信号、广播信号等而接入网络，从而进行与网络的通信。图1中所示出的箭头可以表示通过终端设备10与网络设备20之间的蜂窝链路进行的上/下行传输。
对于上行信号，终端的功率控制在节电和抑制小区间干扰两方面具有重要意义，因此，上行功率控制是LTE重点关注的部分。小区内的上行功率控制，分别包括控制物理上行共享信道(Physical Uplink Shared Channel，PUSCH)、物理上行控制信道(Physical Uplink Control Channel，PUCCH)和探测参考信号(Sounding Reference Signal，SRS)的功率。
在NR中引入了两种上行传输方式：基于码本的传输方式和基于非码本的传输方式。对于基于码本的传输方式，传输所采用的上行波束是通过调度信息中的波束指示信息通知给终端的。终端采用不同的发送波束时，需要采用不同的功率控制参数。所述波束指示信息与上行的功率控制参数相关联，通过波束指示信息可以确定相应的功率控制参数。该关联关系通过RRC信令预先通知终端。
对于非码本的上行传输，网络侧可以为上行SRS或者PUSCH配置一个对应的CSI-RS资源。终端基于所述CSI-RS资源获得下行信道信息，再基于该下行信道信息和信道互易性来得到上行信道信息，根据该上行信道信息计算所述上行SRS或者PUSCH的预编码矩阵。传输采用的上行波束也可以由终端通过上下行波束对应性得到的，即终端可以通过下行信号的接收波束来得到上行信号的发送波束，不需要网络侧的波束指示。此时终端如何为不同的发送波束确定对应的功率控制参数是个问题。
图2示出了本申请实施例的传输信号的方法100的示意性框图。如图2所示，该方法100包括以下部分或全部内容：
S110，终端设备确定与目标上行信号对应的信道状态信息-参考信号CSI-RS资源指示信息；
S120，该终端设备根据该CSI-RS资源指示信息，确定该目标上行信号 的功率控制参数；
S130，该终端设备根据该功率控制参数，确定该目标上行信号的发送功率；
S140，该终端设备根据该发送功率，向网络设备发送该目标上行信号。
具体地，网络设备可以提前配置好或者通过协议约定好一个或多个信道状态信息参考信号(Channel State Information-Reference Signals，CSI-RS)资源，在不同CSI-RS资源上发送的CSI-RS可以采用不同的波束，并且网络设备也可以提前配置好或者通过协议约定好该一个或多个CSI-RS资源与功率控制参数的对应关系或者一个或多个CSI-RS资源指示信息与功率控制参数的对应关系，也就是说，每一个CSI-RS资源或每一个CSI-RS资源指示信息可以对应一组独立的功率控制参数。网络设备可以向终端设备指示使用与哪个CSI-RS资源或CSI-RS资源指示信息对应的功率控制参数进行目标上行信号的传输，终端设备可以在网络设备指示的功率控制参数的基础上进行一定调整，确定目标上行信号的功率控制参数或者也可以直接将网络设备指示的功率控制参数确定为目标上行信号的功率控制参数。终端设备可以根据确定的功率控制参数进一步确定目标上行信号的发送功率，从而根据确定的发送功率向网络设备发送目标上行信号。
因此，本申请实施例的传输信号的方法，通过参考与网络设备发送的CSI-RS资源指示信息对应的功率控制参数来确定目标上行信号的发送功率，有利于提高上行功率控制的准确性，从而能够提高系统传输的性能。
目标上行信号可以是PUSCH、PUCCH或SRS等，本申请实施例对目标上行信号的类型不作限定，只要是上行信号都可以用本申请实施例技术方案确定发送功率。
进一步地，该目标上行信号为基于非码本预编码的PUSCH或为用于获得基于非码本预编码的PUSCH的传输参数的探测参考信号SRS。也就是说，该PUSCH的传输是基于非码本传输方式。例如，终端设备在接收到网络设备发送的CSI-RS资源指示信息，终端设备可以根据该CSI-RS资源指示信息指示的CSI-RS资源获得下行信道信息，再基于该下行信道信息和信道互易性来得到上行信道信息，并根据该上行信道信息计算该PUSCH的预编码信息。终端设备也可以通过波束对应性得到该PUSCH的发送波束，也就是说可以采用终端设备接收CSI-RS的接收波束来得到发送PUSCH的发送波束。 该SRS的传输也可以是基于非码本传输方式。该目标上行信号还可以是用来获取上述PUSCH的传输参数的SRS。
可选地，在本申请实施例中，该CSI-RS资源指示信息指示的CSI-RS资源用于获得该目标上行信号的预编码矩阵或发送波束，或用于获得与该目标上行信号对应的第一SRS的预编码矩阵或发送波束。
前文已经介绍过该CSI-RS资源指示信息指示的CSI-RS资源如何得到PUSCH的预编码矩阵或发送波束，该方法同样适用于任何上行信号，例如，前述PUCCH或SRS。
进一步地，该第一SRS为用于获取该目标上行信号的传输参数的SRS，或该第一SRS为用于调度该目标上行信号的下行控制信息DCI中携带的SRS资源指示信息所指示的SRS资源上传输的SRS。
可选地，在本申请实施例中，上述各种上行信号的传输参数都可以通过第一SRS来获得。该传输参数可以包括以下信息中的至少一项：所用的频域资源、层数、预编码矩阵、调制编码方式和发送波束。也就是说，终端设备接收到CSI-RS资源指示信息后，可以根据其指示的CSI-RS资源及信道互易性，确定出第一SRS的预编码矩阵或发送波束。终端基于该预编码矩阵或发送波束发送该第一SRS后，网络侧可以根据该第一SRS来确定目标上行信号的传输参数，并将所确定的传输参数指示给终端，或者根据所确定的传输参数对终端进行调度。所述第一SRS用于得到所述目标上行信号的传输参数，可以通过所述第一SRS的天线端口数等于所述目标上行信号的传输端口数来实现。
另外，目标上行信号与SRS关联，也可以通过在调度目标上行信号的下行控制信息(Downlink Control Information，DCI)中携带指示SRS资源的SRS资源指示信息来体现。一般地，所述DCI携带的SRS资源指示信息即用于指示与所述目标上行信号关联的SRS资源，在该资源上传输的SRS即为第一SRS。
在本申请实施例中，与目标上行信号对应的CSI-RS资源指示信息中的“对应”可以是指网络设备和终端设备预先约定好或者由网络设备配置好某种指示方式是属于特定的一种上行信号，例如，可以约定好用于调度PUSCH的下行控制信息(Downlink Control Information，DCI)中的某个特定域为该PUSCH对应的CSI-RS资源指示信息。
另外，本领域技术人员理解，CSI-RS资源指示信息可以是用于指示CSI-RS资源的指示信息。例如，网络设备和终端设备预先约定好4种CSI-RS资源，，并提前约定好采用2个bit来指示该4个CSI-RS资源，具体地，CSI-RS资源1对应的指示信息为00，CSI-RS资源2对应的指示信息为01，CSI-RS资源3对应的指示信息为10，CSI-RS资源4对应的指示信息为11。
应理解，本申请实施例中的功率控制参数可以是发送功率的计算公式中的任一项或者多项参数的任意组合。例如，发送功率的计算公式一般包括：终端设备的最大允许发射功率、功率偏移量、上行信号在子帧上的传输带宽、目标接收功率、路径损耗补偿因子、闭环功率调整量和路径损耗等。也就是说，在本申请实施例中，每一个CSI-RS资源或每一个CSI-RS资源指示信息对应的一组功率控制参数包括至少一项参数的取值。
下面将分别以目标上行信号为PUSCH和SRS为例详细描述本申请实施例中的CSI-RS的承载方式。
可选地，在本申请实施例中，该方法还包括：该终端设备接收该网络设备发送的第一信息，该第一信息携带该CSI-RS资源指示信息；该终端设备确定与目标上行信号对应的CSI-RS资源指示信息，包括：该终端设备从该第一信息中，确定该CSI-RS资源指示信息。
应理解，该第一信息可以是如无线资源控制(Radio Resource Control，RRC)信令、媒体接入控制(Media Access Control，MAC)信令等高层信令、DCI信令、系统信息等。
实施例1：如果所述目标上行信号为PUSCH，且所述CSI-RS资源指示信息为网络设备为所述PUSCH配置的CSI-RS资源指示信息，所述CSI-RS资源指示信息可以通过调度该PUSCH的DCI承载。
实施例2：如果该目标上行信号为PUSCH，且该CSI-RS资源指示信息为网络设备为与该PUSCH对应的SRS配置的CSI-RS资源指示信息，那么该CSI-RS资源指示信息可以通过网络设备配置、触发或激活该SRS传输的下行信令承载。具体地，如果该SRS为周期性的SRS，可以通过配置该SRS传输的RRC信令携带该CSI-RS资源指示信息。如果该SRS为非周期性的SRS，可以通过触发该SRS传输的DCI携带该CSI-RS资源指示信息。此时，该DCI的传输资源与该CSI-RS资源指示信息指示的CSI-RS资源可以包含在同一个时隙中。如果该SRS为准持续性SRS，可以通过激活该SRS传输 的MAC信令或者通过RRC信令携带该CSI-RS资源指示信息。
实施例3：如果该目标上行信号为SRS，则该CSI-RS资源指示信息可以通过网络设备配置、触发或激活该SRS传输的下行信令承载。具体地，如果该SRS为周期性的SRS，可以通过配置该SRS传输的RRC信令携带该CSI-RS资源指示信息。如果该SRS为非周期性的SRS，可以通过触发该SRS传输的DCI携带该CSI-RS资源指示信息。此时，该DCI的传输资源与该CSI-RS资源指示信息指示的CSI-RS资源可以包含在同一个时隙中。如果该SRS为准持续性SRS，可以通过激活该SRS传输的MAC信令或者通过RRC信令携带该CSI-RS资源指示信息。
可选地，在本申请实施例中，该方法还包括：该终端设备接收该网络设备发送的配置信息，该配置信息用于指示至少一个CSI-RS资源与至少一组功率控制参数的对应关系，该至少一个CSI-RS资源包括该CSI-RS资源指示信息指示的CSI-RS资源，该至少一组功率控制参数中每组功率控制参数包括至少一个功率控制参数的值；该终端设备根据该CSI-RS资源指示信息，确定该目标上行信号的功率控制参数，包括：该终端设备根据该CSI-RS资源指示信息以及该配置信息，确定该功率控制参数。
可选地，在本申请实施例中，该方法还包括：该终端设备接收该网络设备发送的配置信息，该配置信息用于指示至少一个CSI-RS资源指示信息与至少一组功率控制参数的对应关系，该至少一个CSI-RS资源指示信息包括该CSI-RS资源指示信息，该至少一组功率控制参数中每组功率控制参数包括至少一个功率控制参数的值；该终端设备根据该CSI-RS资源指示信息，确定该目标上行信号的功率控制参数，包括：该终端设备根据该CSI-RS资源指示信息以及该配置信息，确定该功率控制参数。
具体的，网络侧预先配置所述至少一个CSI-RS资源中的每个资源，或者所述至少一个CSI-RS资源指示信息中的每个信息，所对应的一组功率控制参数的取值，从而终端可以根据当前所指示的CSI-RS资源或者当前的CSI-RS资源指示信息来确定对应的一组功率控制参数的取值。这里，一组功率控制参数可以只包含一个功率控制参数，例如开环功率控制参数或者路损值，也可以包含多个参数，例如开环功率控制参数和路损值。
例如，网络设备和终端设备预先约定好4种CSI-RS资源，并且该4种CSI-RS资源分别都有独立的功率控制参数，那么网络设备和终端设备还可 以提前约定好采用2个bit来指示该4个CSI-RS资源，具体地，CSI-RS资源1对应的指示信息为00，CSI-RS资源2对应的指示信息为01，CSI-RS资源3对应的指示信息为10，CSI-RS资源4对应的指示信息为11。也就是说，网络设备可以配置00对应功率控制参数组1，01对应功率控制参数组2，10对应功率控制参数组3，11对应功率控制参数组4。网络设备也可以配置CSI-RS资源1对应功率控制参数组1，CSI-RS资源2对应功率控制参数组2，CSI-RS资源3对应功率控制参数组3，CSI-RS资源4对应功率控制参数组4。其中，功率控制参数组1-4对应同一组功率控制参数的不同取值情况。
CSI-RS资源和CSI-RS资源指示信息中的至少一种与功率控制参数是有对应关系的。也就是说，终端设备在接收到CSI-RS资源指示信息后，根据该指示信息的取值确定与之对应的功率控制参数，终端设备也可以是在接收到CSI-RS资源指示信息后，先根据指示信息确定该指示信息指示的CSI-RS资源，进一步地根据该CSI-RS资源确定与之对应的功率控制参数，本申请对此不构成限定。
可选地，在本申请实施例中，该功率控制参数包括以下信息中的至少一种信息：用于计算该发送功率的路损值、用于测量用于计算该发送功率的路损值的下行信号的信息、开环功率控制参数和闭环功率控制参数。
其中，该用于测量用于计算该发送功率的路损值的下行信号的信息可以认为是路损参考关联信息。也就是说可以是用于对目标上行信号的路径损耗进行估计的下行信号的子集。例如，针对PUSCH的路损参考关联信息可以是指下行导频信号的配置集合中的哪些下行导频信号用于进行路径损耗的测量从而估计PUSCH的路径损耗。该下行信号可以是下行同步信号块(Synchronous signal Block，SSB)、CSI-RS或者物理广播信道(Physical Broadcast Channel，PBCH)、解调参考信号(Demodulation Reference Signal，DMRS)。例如，该终端基于该CSI-RS资源指示信息所指示的CSI-RS资源进行下行路损测量，从而得到该路损值。再例如，该终端根据该CSI-RS资源指示信息确定对应的一个下行信号的索引k，基于该索引k指示的下行信号进行下行路损测量，从而得到该路损值。这里该CSI-RS资源指示信息和下行信号的索引k的对应关系由网络侧通过高层信令预先配置。
可选地，该开环功率控制参数包括目标功率Po的值、路损加权因子a的值、目标功率Po的索引j或路损加权因子a的索引p。其中，索引j从高 层信令预先配置的多个目标功率取值中指示一个目标功率，索引p从高层信令预先配置的多个路损加权因子取值中指示一个路损加权因子。这里，目标功率Po的取值、路损加权因子a的取值、目标功率Po的索引j和路损加权因子的索引p与CSI-RS资源指示信息的对应关系可以由高层信令预先配置好。
可选地，该闭环功率控制参数包括闭环功率控制进程的索引1。其中，索引l从预先定义的至少一个功率控制进程中指示一个功率控制进程，索引l与CSI-RS资源指示信息的对应关系可以由高层信令预先配置好。
可选地，在本申请实施例中，在该终端设备确定与目标上行信号对应的CSI-RS资源指示信息之前，该方法还包括：该终端设备采用该网络设备预配置的功率控制参数，确定该目标上行信号的发送功率。
具体地，如果终端没有接收到网络侧发送的CSI-RS资源指示信息，则采用网络侧预先为所述目标上行信号配置的功率控制参数，直到接收到所述CSI-RS资源指示信息为止。具体的，接收到该CSI-RS资源指示信息后，就采用该CSI-RS资源指示信息对应的功率控制参数来代替网络侧预先配置的值。
图3示出了本申请实施例的传输信号的方法200的示意性框图。如图3所示，该方法200包括以下部分或全部内容：
S210，网络设备向终端设备发送与目标上行信号对应的信道状态信息-参考信号CSI-RS资源指示信息，该CSI-RS资源指示信息用于该终端设备确定该目标上行信号的功率控制参数；
