图1示出本申请实施例可应用的一种无线通信系统的示意图。无线通信系统包括终端11和网络侧设备12。其中，终端11也可以称作终端设备或者用户终端(User Equipment，UE)，终端11可以是手机、平板电脑(Tablet Personal Computer)、膝上型电脑(Laptop Computer)或称为笔记本电脑、个人数字助理(Personal Digital Assistant，PDA)、掌上电脑、上网本、超级移动个人计算机(ultra-mobile personal computer，UMPC)、移动上网装置(Mobile Internet Device，MID)、增强现实(augmented reality，AR)/虚拟现实(virtual reality，VR)设备、机器人、可穿戴式设备(Wearable Device)、车载设备(VUE)、行人终端(PUE)、智能家居(具有无线通信功能的家居设备，如冰箱、电视、洗衣机或者家具等)等终端侧设备，可穿戴式设备包括：智能手表、智能手环、智能耳机、智能眼镜、智能首饰(智能手镯、智能手链、智能戒指、智能项链、智能脚镯、智能脚链等)、智能腕带、智能服装、游戏机等。需要说明的是，在本申请实施例并不限定终端11的具体类型。网络侧设备12可以是基站或核心网，其中，基站可被称为节点B、演进节点B、接入点、基收发机站(Base Transceiver Station，BTS)、无线电基站、无线电收发机、基本服务集(Basic  Service Set，BSS)、扩展服务集(Extended Service Set，ESS)、B节点、演进型B节点(eNB)、下一代节点B(gNB)、家用B节点、家用演进型B节点、WLAN接入点、WiFi节点、发送接收点(TransmittingReceivingPoint，TRP)或所述领域中其他某个合适的术语，只要达到相同的技术效果，所述基站不限于特定技术词汇，需要说明的是，在本申请实施例中仅以NR系统中的基站为例，但是并不限定基站的具体类型。
下面结合附图，通过一些实施例及其应用场景对本申请实施例提供的SRS的传输方法、装置、终端及网络侧设备进行详细地说明。
本申请各个实施例可以应用在基于非码本的物理上行共享信道(Physical Uplink Shared Channel，PUSCH)传输的场景中，也即，终端可以首先接收信道状态信息参考信号(Channel State Information-Reference Signal，CSI-RS)，通过接收的CSI-RS获得下行信道状态信息。
根据信道互易性，该下行信道信息可以近似等效为上行信道信息，这样，终端即可根据上行信道信息来计算候选的用于上行传输的预编码，并根据该预编码对SRS进行预编码并发送，该SRS与上述CSI-RS关联。
终端发送SRS之后，网络侧设备还可以根据测量预编码后的SRS来进一步确定PUSCH传输所使用的预编码，并通过调度PUSCH的下行控制信息(Downlink Control Information，DCI)来通知给终端，终端即可使用网络侧设备指示的预编码来发送PUSCH。
本申请后续多个实施例多以非码本的PUSCH传输的场景为例介绍SRS该如何传输，可以理解，本申请实施例提供的SRS的传输方法并不以上述非码本的PUSCH传输的场景为限。
如图2所示，本申请实施例提供一种SRS的传输方法200，该方法可以由终端执行，换言之，该方法可以由安装在终端的软件或硬件来执行，该方法包括如下步骤。
S202：终端确定SRS的发送参数，所述发送参数包括如下至少之一：传输配置指示(Transmission Configuration Indicator，TCI)状态，预编码，功率 控制参数。
在一个实施例中，所述发送参数包括TCI状态，该实施例可以应用在基于非码本的PUSCH传输的场景中，所述SRS配置有关联的CSI-RS。这样，SRS使用的TCI状态可以参考CSI-RS的TCI状态，例如，SRS的波束信息参考CSI-RS的波束信息，使得SRS和CSI-RS使用相同的波束进行传输。
在其他的例子中，在本申请实施例可以应用在统一的TCI架构中，其中，统一的TCI架构即为终端上下行传输采用统一的一套波束指示信息。例如，上下行统一使用一个波束，上下行所有信道和/或信号都应用一个TCI状态(称作是联合TCI状态)，即SRS以及关联的CSI-RS均使用该联合TCI状态进行传输。
在另一个实施例中，所述发送参数包括预编码，该实施例可以应用在基于非码本的PUSCH传输的场景中，所述SRS配置有关联的CSI-RS。这样，终端可以根据所述CSI-RS计算所述SRS的预编码。
在其他的例子中，所述SRS没有配置关联的CSI-RS，终端还可以根据目标参考信号来计算所述SRS的预编码，该目标参考信号将在后续实施例中详细介绍。
在再一个实施例中，所述发送参数包括功率控制参数，该实施例可以应用在基于非码本的PUSCH传输的场景中，所述SRS配置有关联的CSI-RS。这样，终端可以根据第一命令确定功率控制参数。
该实施例中，第一命令可以用于指示TCI状态，第一命令指示的TCI状态包括如下至少之一：联合TCI状态；分离TCI状态，所述分离TCI状态包括上行TCI状态和下行TCI状态。
本申请各个实施例中提到的联合TCI状态，可以是终端上下行传输采用统一的一套波束指示信息，即采用统一的一个联合TCI状态；本申请各个实施例中提到的分离TCI状，可以是DCI指示两个分离TCI状态，一个下行TCI状态应用于下行信道或信号，一个上行TCI状态应用于上行信道或信号。
需要说明的是，上述多个实施例分别介绍了终端如何确定用于SRS传输的 TCI状态，预编码以及功率控制参数，实际上，上述多个实施例可以根据需要进行组合，使得终端可以同时采用上述一个或多个实施例来确定SRS的发送参数。
S204：终端根据所述发送参数发送所述SRS。
上述介绍了终端如何确定SRS的发送参数，该步骤中，终端即可根据确定出的发送参数发送SRS。可以理解，终端发送SRS可能还需要上述发送参数之外的参数，这些参数可以根据协议约定或网络侧设备指示得到。
本申请实施例提供的SRS的传输方法，终端确定SRS的发送参数，并根据确定出的发送参数发送SRS，该发送参数包括如下至少之一：TCI状态，预编码，功率控制参数。本申请实施例有利于SRS得到有效传输，进而通过SRS测量，获得用于PUSCH的传输参数，进一步提高上行数据传输的性能。
本申请各个实施例提供的SRS的传输方法可以应用在统一的TCI架构中，使得SRS得到有效传输。其中，统一的TCI架构即为终端上下行传输采用统一的一套波束指示信息。例如，一种是上下行统一使用一个波束。当DCI指示了一个TCI状态，则上下行所有信道和/或信号都应用该TCI状态(称作是联合TCI状态)。另一种方案是DCI指示一对波束，即两个TCI状态，一个应用于下行信道或信号，一个应用于上行信道或信号，这两个TCI状态可以称作是分离TCI状态。
可选地，以实施例200为基础，所述终端确定SRS的发送参数之前，所述方法还包括：所述终端接收CSI-RS，所述CSI-RS与所述SRS关联，所述CSI-RS使用第一命令指示的下行TCI状态；其中，所述第一命令指示的TCI状态可以包括如下至少之一：联合TCI状态，所述联合TCI状态同时作为上行TCI状态和所述下行TCI状态；分离TCI状态，所述分离TCI状态包括上行TCI状态和所述下行TCI状态，该实施例假设第一命令指示的TCI状态包括联合TCI状态，或包括分离TCI状态中的下行TCI状态。该实施例可以应用在基于非码本的PUSCH传输的场景中。
在一个实施例中，所述第一命令指示的TCI状态为所述联合TCI状态，所 述发送参数包括TCI状态，所述终端确定SRS的发送参数包括：所述终端将所述联合TCI状态作为所述SRS的TCI状态。
在该实施例中，非码本的PUSCH传输的场景中的CSI-RS以及PUSCH均可以使用所述联合TCI状态；也即，该实施例中的SRS用于PUSCH传输。
在该实施例中，所述终端确定SRS的发送参数还可以包括：所述终端将所述联合TCI状态所包含或关联的用于SRS传输的功率控制参数作为所述SRS的功率控制参数。
在另一个实施例中，所述第一命令指示的TCI状态为所述分离TCI状态，所述CSI-RS使用第一命令下行TCI状态。该实施例中，所述终端确定SRS的发送参数包括：所述终端将所述上行TCI状态所包含或关联的用于SRS传输的功率控制参数作为所述SRS的功率控制参数。
该实施例中，在终端根据第一命令确定功率控制参数的情况下，终端发送SRS使用的波束信息可以参考CSI-RS的波束信息，使得SRS和CSI-RS使用相同的波束进行传输。
在该实施例中，终端还可以发送PUSCH；其中，所述发送PUSCH参考所述上行TCI状态所包含或关联的用于PUSCH传输的功率控制参数，也即，该实施例中的SRS用于PUSCH传输。
在该实施例中，所述SRS和/或所述PUSCH可以忽略第一信息，所述第一信息为所述上行TCI状态包含或关联的信息中所述功率控制参数之外的信息。
上述各个实施例中，在所述发送参数包括预编码的情况下，所述终端确定SRS的发送参数包括：所述终端根据所述CSI-RS计算所述SRS的预编码。
可选地，以实施例200为基础，所述发送参数包括TCI状态，所述终端确定SRS的发送参数包括：所述终端将第一命令指示的上行TCI状态作为所述SRS的TCI状态；其中，所述第一命令指示的TCI状态包括如下至少之一：联合TCI状态，所述联合TCI状态同时作为下行TCI状态和所述上行TCI状态；分离TCI状态，所述分离TCI状态包括所述上行TCI状态和下行TCI状态，该实施例假设第一命令指示的TCI状态包括联合TCI状态，或包括分离TCI 状态的上行TCI状态。
该实施例例如，终端将第一命令指示的分离TCI状态中的上行TCI状态作为所述SRS的TCI状态。
在上述实施例的基础上，所述终端确定SRS的发送参数之前，所述方法还包括：所述终端接收CSI-RS，所述CSI-RS与所述SRS关联，所述CSI-RS不使用第一命令指示的TCI状态，例如，所述CSI-RS不使用第一命令指示的分离TCI状态中的下行TCI状态。
该实施例满足如下条件之一：
1)第一命令指示的TCI状态中的QCL类型D的参考信号与所述CSI-RS关联的TCI状态中的参考信号相同。
2)所述CSI-RS与第一命令指示的TCI状态中的QCL对应的参考信号是准共址的。
通过上述两个条件的至少之一的限制，在基于非码本的PUSCH传输的场景中，使得SRS和CSI-RS使用相同的波束进行传输，这样，通过CSI-RS计算出的SRS的预编码更准确，提高SRS以及PUSCH的传输质量，提高通信效率。
可选地，以实施例200为基础，所述SRS没有配置关联的CSI-RS，所述终端确定SRS的发送参数包括：所述终端根据目标参考信号计算所述SRS使用的预编码；其中，所述目标参考信号为如下之一：
1)距离所述SRS最近，且与所述SRS关联相同的TCI状态的非零功率CSI-RS。可选地，所述SRS为非周期，半持续，周期至少一种情况，相应地，CSI-RS也可以是非周期，半持续，周期至少一种情况。
2)距离所述SRS大于或等于X个时间单位之外最近，且与所述SRS关联相同TCI状态的非零功率CSI-RS，X为正整数。上述时间单位可以为时隙，正交频分复用(Orthogonal Frequency Division Multiplexing，OFDM)符号，毫秒等。
3)目标资源被指示的TCI状态中的CSI-RS。
4)第二命令配置或更新的CSI-RS。该第二命令可以为无线资源控制(Radio Resource Control，RRC)命令，还可以为媒体接入控制控制单元(Media Access Control-Control Element，MAC CE)命令。
该实施例可以应用在统一的TCI架构中，使得SRS得到有效传输。该实施例可以应用在基于非码本的PUSCH传输的场景中，也可以应用在上述场景之外。
可选地，以实施例200为基础，所述终端确定SRS的发送参数包括：所述终端根据所述SRS所属的资源集，确定所述SRS的发送参数；其中，所述资源集包括第一SRS资源集和第二SRS资源集，所述第一SRS资源集参考联合TCI状态；所述第二SRS资源集参考分离TCI状态。
需要说明的是，该实施例中提到的第一SRS资源集和第二SRS资源集，可以是按照SRS资源集的标识大小(或小大)排序后的第一个SRS资源集和第二个SRS资源集。因此，上述第一SRS资源集参考联合TCI状态，第二SRS资源集参考分离TCI状态，在其他的例子中，还可以替换为第二SRS资源集参考联合TCI状态，第一SRS资源集参考分离TCI状态。
可选地，所述第一SRS资源集参考联合TCI状态包括：所述第一SRS资源集中的SRS，所述第一SRS资源集中的SRS关联的CSI-RS，所述第一SRS资源集中的SRS关联的PUSCH均使用所述联合TCI状态。
可选地，所述分离TCI状态包括上行TCI状态和下行TCI状态，所述第二SRS资源集参考分离TCI状态包括如下至少之一：
1)所述第二SRS资源集中的SRS关联的CSI-RS使用所述下行TCI状态；
2)所述第二SRS资源集中的SRS，所述第二SRS资源集中的SRS关联的PUSCH均参考第二信息，而忽略第一信息，所述第二信息为所述上行TCI状态所包含或关联的功率控制参数，所述第一信息为所述上行TCI状态包含或关联的信息中所述功率控制参数之外的信息。
该实施例例如，第一命令同时指示了联合(joint)TCI状态和分离(separate)TCI状态，该实施例中提到的联合TCI状态，可以是终端上下行传输采用统一 的一套波束指示信息(如统一的一个联合TCI状态)；该实施例中提到的分离TCI状态，可以是DCI指示一对波束，即两个TCI状态，一个下行TCI状态应用于下行信道或信号，一个上行TCI状态应用于上行信道或信号。
该实施例假设RRC为终端配置了SRS资源集，该SRS资源集包括第一SRS资源集和第二SRS资源集，其中，RRC配置的第一SRS资源集可以参考联合TCI状态，同时，第一SRS资源集中的SRS资源，相关联的CSI-RS以及PUSCH均参考联合TCI状态。
RRC配置的第二SRS资源集参考分离TCI状态。具体地，第二SRS资源集中的SRS资源关联的CSI-RS应用下行TCI状态，第二SRS资源集中的SRS资源以及关联的PUSCH，仅参考上行TCI状态关联或者包含的功率控制参数集合，忽略其他信息。该实施例中，第二SRS资源集中的SRS资源以及关联的PUSCH的波束信息参考CSI-RS的波束信息。
上述将SRS资源集分为第一SRS资源集和第二SRS资源集的分组方法，可以是直接按照SRS资源组来区分。
具体例如，RRC配置了两个SRS资源集，SRS资源集1和SRS资源集2，SRS资源集1关联CSI-RS 1，SRS资源集2关联CSI-RS 2。
如果第一命令指示的是联合TCI状态，则SRS资源集1，CSI-RS 1以及关联来自SRS资源集1的PUSCH应用所述联合TCI状态。
第二个TCI状态是分离TCI状态，包含一个下行TCI状态一个上行TCI状态，CSI-RS 2应用下行TCI状态，来自SRS资源集2的SRS资源以及关联所述SRS资源的PUSCH仅参考上行TCI状态关联或者包含的功率控制参数集合，忽略其他信息。
可选地，所述终端确定SRS的发送参数之前，所述方法还包括：所述终端接收第二命令，所述第二命令用于指示如下至少之一：TCI状态的资源池；TCI状态的模式，其中，所述TCI状态的模式包括联合指示或分离指示。
该实施例中提到的联合指示，可以是终端上下行传输采用统一的一套波束指示信息(如统一的一个联合TCI状态)；本申请各个实施例中提到的分离指 示，可以是DCI指示一对波束，即两个分离TCI状态，一个应用于下行信道或信号，一个应用于上行信道或信号。
在多TRP场景中，终端或SRS可以被指示多个联合TCI状态，每个联合TCI状态对应一个TRP；终端或SRS还可以被指示多组分离TCI状态，每组分离TCI状态对应一个TRP。
该实施例中，TCI状态的资源池以及TCI状态的模式等，可以满足如下至少之一：
1)所述TCI状态的资源池与控制资源集资源池索引(CORESETPoolIndex)关联。由于CORESETPoolIndex与TRP关联，因此，TCI状态的资源池也与TRP关联。
2)所述TCI状态的模式与CORESETPoolIndex关联。由于CORESETPoolIndex与TRP关联，因此，TCI状态的模式也与TRP关联。
3)所述TCI状态的资源池与所述第一SRS资源集关联。
4)所述TCI状态的模式与所述第一SRS资源集关联。
5)所述TCI状态的资源池与所述第二SRS资源集关联。
6)所述TCI状态的模式与所述第二SRS资源集关联。
7)所述TCI状态的资源池与所述TCI状态的模式关联。
该实施例中，网络侧设备可以配置TCI状态指示模式是分离的还是联合的，这些指示模式可以与TRP关联，该TRP可以用SRS资源集的标识进行区分，还可以用TCI状态的资源池标识进行区分。
通过上述关联关系，在多发送接收点/多天线面板(multi-TRP/multi-panel，后续统一简称为M-TRP或多TRP)场景中，可以基于终端的能力以及信道条件来针对不同TRP配置不同的TCI状态指示模式，增加网络配置灵活性，同时也保证了上行传输的性能。
可选地，以实施例200为基础，终端满足如下至少之一：
1)所述SRS关联有CSI-RS，所述终端被配置为上下行波束联合指示，该例子中终端不期望被配置为分离TCI状态指示。该实施例使得SRS和CSI-RS 使用相同的波束进行传输，这样，通过CSI-RS计算出的SRS的预编码更准确，提高SRS以及PUSCH的传输质量，提高通信效率。
2)所述SRS关联的CSI-RS使用第一命令指示的TCI状态，第一命令可以参见前文实施例的介绍。
3)第一命令指示的TCI状态所关联的QCL关系对所述SRS和/或PUSCH不生效，其中，所述SRS用于所述PUSCH传输，第一命令可以参见前文实施例的介绍。可选地，该实施例中的QCL关系可以为类型D的QCL关系。
