通常来说，传统的通信系统支持的连接数有限，也易于实现，然而，随着通信技术的发展，移动通信系统将不仅支持传统的通信，还将支持例如，设备到设备(Device to Device，D2D)通信，机器到机器(Machine to Machine，M2M)通信，机器类型通信(Machine Type Communication，MTC)，以及车辆间(Vehicle to Vehicle，V2V)通信等，本申请实施例也可以应用于这些通信系统。
可选地，本申请实施例中的通信系统可以应用于载波聚合(Carrier Aggregation，CA)场景，也可以应用于双连接(Dual Connectivity，DC)场景，还可以应用于独立(Standalone，SA)布网场景。
示例性的，本申请实施例应用的通信系统100如图1所示。该无线通信系统100可以包括网络设备110。网络设备110可以是与终端设备通信的设备。网络设备110可以为特定的地理区域提供通信覆盖，并且可以与位于该覆盖区域内的终端设备进行通信。可选地，该网络设备100可以是GSM系统或CDMA系统中的基站(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 Node B，eNB或eNodeB)，或者是NR系统中的网络侧设备，或者是云无线接入网络(Cloud Radio Access Network，CRAN)中的无线控制器，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、下一代网络中的网络侧设备或者未来演进的公共陆地移动网络(Public Land Mobile Network，PLMN)中的网络设备等。
该无线通信系统100还包括位于网络设备110覆盖范围内的至少一个终端设备120。作为在此使用的“终端设备”包括但不限于经由有线线路连接，如经由公共交换电话网络(Public Switched Telephone Networks，PSTN)、数字用户线路(Digital Subscriber Line，DSL)、数字电缆、直接电缆连接；和/或另一数据连接/网络；和/或经由无线接口，如，针对蜂窝网络、无线局域网(Wireless Local Area Network，WLAN)、诸如DVB-H网络的数字电视网络、卫星网络、AM-FM广播发送器；和/或另一终端设备的被设置成接收/发送通信信号的装置；和/或物联网(Internet of Things，IoT)设备。被设置成通过无线接口通信的终端设备可以被称为“无线通信终端”、“无线终端”或“移动终端”。
终端设备120可以是移动的或固定的。可选地，终端设备120可以指接入终端、用户设备(User Equipment，UE)、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PLMN中的终端设备等。其中，可选地，终端设备120之间也可以进行终端直连(Device to Device，D2D)通信。
具体地，网络设备110可以为小区提供服务，终端设备120通过该小区使用的传输资源(例如，频域资源，或者说，频谱资源)与网络设备110进行通信，该小区可以是网络设备110(例如基站)对应的小区，小区可以属于宏基站，也可以属于小小区(Small cell)对应的基站，这里的小小区可以包括：城市小区(Metro cell)、微小区(Micro cell)、微微小区(Pico cell)、毫微微小区(Femto cell)等，这些小小区具有覆盖范围小、发射功率低的特点，适用于提供高速率的数据传输服务。
图1示例性地示出了一个网络设备和两个终端设备，可选地，该无线通信系统100可以包括多个网络设备并且每个网络设备的覆盖范围内可以包括其它数量的终端设备，本申请实施例对此不做限 定。可选地，该无线通信系统100还可以包括网络控制器、移动管理实体等其他网络实体，本申请实施例对此不作限定。
以NR系统为例，网络设备可以为每个下行信号配置相应的传输配置指示(transmission configuration indicator，TCI)状态，终端设备可以基于此配置进行下行信号的接收。
可选地，一个TCI状态中可以包含以下中的至少一个：信道状态信息参考信号(channel state information reference signal，CSI-RS)资源的索引、同步信号块(synchronization signal block，SSB)索引和PTRS端口。
其中，CSI-RS资源的索引可以为CSI-RS资源的身份(identity，ID)。
不同的CSI-RS可以由不同的资源来发送，不同的SRS也可以由不同的资源来发送。
可选地，终端设备可以基于TCI状态中的CSI-RS资源索引和/或SSB索引来确定下行信号的空间接收参数，该空间接收参数可以用于指示接收所述下行信号所使用的波束或者天线面板(panel)。
以CSI-RS为例，网络设备可以使用不同的波束向终端设备发送多个CSI-RS，终端设备可以根据CSI-RS的接收情况，向网络设备上报选择CSI-RS。
可选地，终端设备可以向网络设备上报接收质量最好的CSI-RS的CSI-RS资源的索引。或者终端设备可以向网络设备上报至少一个CSI-RS资源上的接收质量，该上报信息中包括至少一个CSI-RS资源的索引值以及该资源上的信号接收质量等。
之后，网络设备在发送下行信号时，可以为每个下行信号配置TCI状态，TCI状态中包括CSI-RS资源的索引。终端设备可以假设下行信号与该CSI-RS资源上的CSI-RS采用相同的波束，从而采用与所述CSI-RS资源相同的接收波束来接收该下行信号。
以SRS为例，终端设备可以采用不同的波束向网络设备发送多个SRS，网络设备可以根据SRS的接收质量，向终端设备发送SRS资源指示信息，指示其中接收质量最好的SRS资源，从而令终端设备使用发送该SRS资源的波束来发送后续的其他信号。
上文是以波束为例，对终端设备根据下行信号的至少一个TCI状态来确定接收下行信号所采用的波束进行描述。对于天线面板来说，也同样适用于此方法。
以CSI-RS为例，网络设备可以使用不同的天线面板来发送多个CSI-RS，终端设备可以采用不同的天线面板来接收CSI-RS。之后，网络设备可以在发送的下行信号的至少一个TCI状态中指示一个CSI-RS资源的索引，终端设备可以根据该CSI-RS资源的索引确定接收该CSI-RS资源上的CSI-RS所使用的天线面板，并采用该天线面板来接收下行信号。
以SRS为例，终端设备可以使用不同的天线面板来发送多个SRS，网络设备可以根据SRS的接收质量，向终端设备发送SRS资源指示信息，指示其中接收质量最好的SRS资源，从而令终端设备使用发送该SRS资源的天线面板来发送后续的其他信号。
需要说明的是，本申请实施例中的波束可以是由天线面板来形成的，一个方向上的波束也可以是由多个天线面板来形成，也可以是由一个天线面板来形成。一个天线面板可以形成一个方向的波束，也可以形成不同方向的波束。
可选地，本申请实施例中的波束也可以称为空间域传输滤波器(spatial domain transmission filter)。
如果网络设备在某个下行信号的至少一个TCI状态中指示了一个CSI-RS资源，则终端设备可以假设该下行信号与该CSI-RS资源采用相同的波束或天线面板，从而终端设备可以采用接收该CSI-RS资源所采用的波束或天线面板来接收该下行信号。
如果网络设备在某个下行信号中指示了一个SSB索引，则终端设备可以假设该下行信号与该SSB索引所指示的SSB采用相同的波束或天线面板，从而终端设备可以采用发送该SSB所采用的波束来接收该下行信号。
以NR系统为例，网络设备可以采用多个TRP、天线面板或波束独立地向终端设备发送多个下行信号，终端设备可能需要向该多个TRP、天线面板或波束分别发送下行信号对应的上行信号。在接收下行信号时，终端设备可以采用不同的天线面板或波束来接收不同的下行信号。如果终端设备发送下行信号对应的上行信号所采用的波束或天线面板与接收下行信号所采用的波束或天线面板不同时，则终端设备发送下行信号对应的上行信号所使用的波束可能会没有对准对应的TRP或天线面板，导致发送给对应的TRP或天线面板的上行信号的传输性能较差。
本申请实施例提供了一种传输上行信号的方法和设备，能够保证终端设备上行传输的可靠性。
图2是本申请实施例提供的一种传输上行信号的方法的示意图。图2的方法包括步骤210-230。
在步骤210中，终端设备接收网络设备发送的下行信号。
可选地，该下行信号可以为以下中的至少一个：物理下行共享信道(physical downlink shared channel，PDSCH)，物理下行控制信道(physical downlink control channel，PDCCH)，或CSI-RS等。
其中，PDSCH可以用于承载数据信息或高层信令等。例如，PDSCH可以用于传输数据，或者PDSCH可以用于承载无线资源控制(radio resource control，RRC)信令，或者PDSCH可以用于承载介质访问控制(medium access control，MAC)信令。

本申请实施例提供的技术方案中，下行信号对应的上行信号的空间相关信息是根据下行信号的TCI状态来确定。由于下行信号的TCI状态与发送下行信号的TRP或天线面板相关联，不同的TRP或天线面板具有各自独立的TCI状态。这样，通过下行信号的TCI状态确定的下行信号对应的上行信号的空间相关信息也是与TRP或天线面板相关联的，因此，终端设备基于该空间相关信息发送下行信号对应的上行信号时，能够对准发送下行信号的TRP或天线面板，保证了终端设备通过TRP或天线面板接收信号的质量，从而能够保证通信质量。
图3是本申请实施例提供的另一种上行信号的传输方法的示意图，图3的方法包括步骤310-330。
在步骤310中，网络设备向终端设备发送下行信号。
可选地，该下行信号可以为PDSCH，PDCCH，和/或CSI-RS等。
其中，PDSCH可以用于承载数据信息或高层信令等。例如，PDSCH可以用于传输数据，或者PDSCH可以用于承载RRC信令，或者PDSCH可以用于承载MAC信令。

在步骤330中，网络设备采用该空间相关信息接收终端设备发送的下行信号对应的上行信号。
本申请实施例提供的技术方案中，下行信号对应的上行信号的空间相关信息是根据下行信号的TCI状态来确定。由于下行信号的TCI状态与发送下行信号的TRP或天线面板相关联，不同的TRP或天线面板具有各自独立的TCI状态。这样，通过下行信号的TCI状态确定的下行信号对应的上行信号的空间相关信息也是与TRP或天线面板相关联的，因此，终端设备基于该空间相关信息发送下行信号对应的上行信号时，能够对准发送下行信号的TRP或天线面板，保证了终端设备通过TRP或天线面板接收信号的质量，从而能够保证通信质量。
上行信号与下行信号有多种对应关系，下面对下行信号对应的上行信号的多种形式进行详细描述。
应理解，下文的描述可以适用于图2所示的方法，也可以适用于图3所示的方法。
在下行信号为PDSCH的情况下，下行信号对应的上行信号可以为PUCCH或者SRS。
作为一个示例，下行信号PDSCH可以承载用户数据信息，终端设备可能需要对PDSCH的接收情况向网络设备进行数据对应的应答(acknowledgment，ACK)/否定应答(negative-acknowledgment，NACK)反馈。此时，下行信号对应的上行信号可以为PUCCH，该PUCCH用于承载PDSCH的ACK/NACK反馈信息。
网络设备可以采用不同的波束向终端设备发送多个PDSCH，此时终端设备可能需要根据该多个PDSCH中每个PDSCH的接收情况，向网络设备进行ACK/NACK反馈。
例如，网络设备可以采用不同的波束向终端设备发送第一PDSCH和第二PDSCH，终端设备对第一PDSCH进行ACK/NACK反馈时，可以采用第一PUCCH承载第一PDSCH的ACK/NACK反馈信息。在发送第一PUCCH时，终端设备可以根据第一PDSCH的TCI状态来确定第一PUCCH的空间相关信息，然后可以采用该第一PUCCH的空间相关信息来发送第一PUCCH。
同样地，终端设备在对第二PDSCH进行ACK/NACK反馈时，可以采用第二PUCCH承载第二PDSCH的ACK/NACK反馈信息。在发送第二PUCCH时，终端设备可以根据第二PDSCH的TCI状态来确定第二PUCCH的空间相关信息，然后可以采用该第二PUCCH的空间相关信息来发送第二PUCCH。
可选地，当终端设备接收到网络设备发送的多个PDSCH后，可以采用上文描述的对每一个PDSCH进行反馈时，都采用一个独立的PUCCH进行ACK/NACK反馈的方式，也可以将多个PDSCH的ACK/NACK反馈信息承载在一个PUCCH上进行反馈。
终端设备可以采用不同的波束来接收多个PDSCH，针对该多个PDSCH，终端设备可以将该多个PDSCH中的至少两个PDSCH的ACK/NACK反馈信息承载在一个PUCCH上，然后向网络设备发送该PUCCH。
步骤220可以进一步包括：终端设备可以根据多个下行信号中的至少一个下行信号的TCI状态来确定下行信号对应的上行信号的空间相关信息。也就说，终端设备可以根据多个PDCSH中的至少一个PDSCH的TCI状态来确定PUCCH的空间相关信息。
优选地，PUCCH所采用的空间相关信息可以根据该多个PDSCH中最后一个接收的PDSCH的TCI状态来确定。
网络设备可以采用不同的波束向终端设备发送第一PDSCH和第二PDSCH，终端设备针对该第一PDSCH和第二PDSCH进行ACK/NACK反馈时，可以将该两个ACK/NACK反馈信息承载在一个PUCCH上向网络设备发送。该PUCCH所采用的空间相关信息可以是根据第一PDSCH的TCI状态来确定的，也可以是根据第二PDSCH的TCI状态来确定的。
如果终端设备接收第二PDSCH的时间晚于第一PDSCH，则终端设备可以优先采用第二PDSCH的TCI状态确定的空间相关信息来发送该PUCCH。
可选地，当多个PDSCH的TCI状态相同时，终端设备可以将该多个PDSCH的ACK/NACK反馈信息承载在一个PUCCH上，并将该PUCCH发送给网络设备。终端设备发送该PUCCH所使用的空间相关信息可以是根据该相同的TCI状态来确定的。
作为另一个示例，PDSCH可以承载RRC信令，该RRC信令可以用于配置CSI上报。终端设备收到该PDSCH后，可以向网络设备发送PUCCH，该PUCCH用于承载所配置的CSI上报的信息。此时，下行信号为承载RRC信令的PDSCH，下行信号对应的上行信号为承载对应CSI上报的PUCCH。
RRC信令还可以配置CSI上报的周期和/或上报方式等。

该DCI可以用于触发SRS，终端设备可以基于该DCI向网络设备发送SRS。此时，下行信号PDCCH对应的上行信号为DCI触发的SRS。
在下行信号为CSI-RS的情况下，下行信号对应的上行信号为PUSCH、PUCCH或SRS。
终端设备可以基于CSI-RS对CSI进行测量，并将测量得到的CSI承载在PUSCH或PUCCH上。此时，下行信号CSI-RS对应的上行信号为承载CSI的PUSCH或PUCCH。
在下行信号为CSI-RS的情况下，下行信号对应的上行信号可以为SRS，其中，SRS的预编码向量是根据从CSI-RS测量得到的信道信息确定的。
可选地，终端设备在发送SRS之前，可以根据预设的至少一个CSI-RS与至少一个SRS的对应关系，选择要向网络设备发送的SRS。
至少一个CSI-RS与至少一个SRS的对应关系可以指，发送CSI-RS的CSI-RS资源与发送SRS的SRS资源的对应。例如，网络设备可以通过高层信令为不同的SRS资源配置不同的CSI-RS资源，用于得到该SRS资源的预编码向量。
