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描述，显然，所描述的实施例是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。

应理解，本文中术语“***”和“网络”在本文中常被可互换使用。本文中术语“和/或”，仅仅是一种描述关联对象的关联关系，表示可以存在三种关系，例如，A和/或B，可以表示：单独存在A，同时存在A和B，单独存在B这三种情况。另外，本文中字符“/”，一般表示前后关联对象是一种“或”的关系。
下面对几个概念进行详细介绍。
一、NR-U***
免授权频谱是国家和地区划分的可用于无线电设备通信的频谱，该频谱通常被认为是共享频谱，即不同通信***中的通信设备只要满足国家或地区在该频谱上设置的法规要求，就可以使用该频谱，不需要向政府申请专有的频谱授权。为了让使用免授权频谱进行无线通信的各个通信***在该频谱上能够友好共存，一些国家或地区规定了使用免授权频谱必须满足的法规要求。例如，在欧洲地区，通信设备遵循“先听后说(listen-before-talk，LBT)”原则，即通信设备在免授权频谱的信道上进行信号发送前，需要先进行信道侦听，只有当信道侦听结果为信道空闲时，该通信设备才能进行信号发送；如果通信设备在免授权频谱的信道上的信道侦听结果为信道忙，该通信设备不能进行信 号发送。且为了保证公平性，在一次传输中，通信设备使用免授权频谱的信道进行信号传输的时长不能超过最大信道占用时间(Maximum Channel Occupation Time，MCOT)。
二、NR***中的同步信号(Synchronization Signal，SS)/物理广播信道(Physical Broadcast Channel，PBCH)块(block)
在NR***中的公共信道和信号，如同步信号和广播信道，需要通过多波束扫描的方式覆盖整个小区，便于小区内的UE接收。同步信号的多波束发送是通过定义SS/PBCH脉冲集合(burst set)实现的。一个SS burst set包含一个或多个SS/PBCH block。一个SS/PBCH block用于承载一个波束的同步信号和广播信道。因此，一个SS/PBCH burst set可以包含小区内SS/PBCH block个数(number)个波束的同步信号。SS/PBCH block number的最大数目可以表示为L，L与***的频段有关，例如，频率范围为小于或者等于3GHz，L取4；频率范围为3GHz到6GHz，L取8；频率范围为6GHz到52.6GHz，L取64。
图2示出了一个SS/PBCH block(下述简称为“SSB”)占用的时频资源的示意图。如图2所示，一个SSB中可以包括一个正交频分复用(Orthogonal Frequency Division Multiplexing，OFDM)符号的主同步信号(Primary Synchronization Signal，PSS)，还可以包括一个OFDM符号的辅同步信号(Secondary Synchronization Signal，SSS)以及两个OFDM符号的NR-PBCH，其中，PBCH所占的时频资源中，可以包括解调参考信号(Demodulation Reference Signal，DMRS)，该DMRS用于PBCH的解调。
SS/PBCH burst set内所有的SS/PBCH block在5ms的时间窗内发送，并以一定的周期重复发送，该周期可以通过高层的参数SSB时间(SSB-timing)信息进行配置，例如，该周期可以包括5ms、10ms、20ms、40ms、80ms和160ms等。对于UE来说，通过接收到的SS/PBCH block得到该SSB的索引(index)，SSB index对应该SSB在5ms时间窗内的相对位置，UE根据该信息和PBCH中承载的半帧指示信息，获得帧同步。其中，SS/PBCH block的index可以通过PBCH的DMRS或者PBCH承载的信息来指示。
图3示出了本申请实施例的在不同的子载波间隔(subcarrier spacing，SCS)下SSB的时隙分布图样。以15kHz子载波间隔，L＝4为例，一个时隙(slot)包含14个符号(symbol)，可以承载两个SS/PBCH block，在5ms时间窗内的前两个slot内共分布4个SS/PBCH block。
应理解，本申请实施例中的SSB的个数L为最大的SSB的个数，也就是说实际发送的SSB的个数可以小于或者等于L。在NR***中，由于在一定的频段上，L为发送的SSB的最大个数，则SSB index的取值范围为[0,L-1]。SSB index可以用于帧同步，另一方面，也可以用于UE获得SSB的QCL关系。在不同的时间接收到的SS/PBCH block的index相同，则认为它们之间具有QCL关系。
当两个参考信号(比如SSB)具有QCL关系的时候，可以认为这两个参考信号的大尺度参数是可以相互推断的，或者可以认为是类似的，其中，大尺度参数可以包括如多普勒时延、平均时延和空间接收参数等。在测量时UE可以将具有QCL关系的SSB做滤波处理，作为波束级别的测量结果。
三、NR-U***中的发现参考信号(Discovery reference signal，DRS)
在NR-U***中，对于一个主小区(Primary Cell，Pcell)，网络设备发送DRS信号可以用于接入和测量等，其中，DRS至少可以包括SSB。考虑到非授权频谱上信道使用权获得的不确定性，网络设备在SSB的发送过程中，由于存在LBT失败的可能，在预定的时刻可能无法成功发送SSB。因此，NR-U定义了SSB的候选位置。例如，在一个最长5ms的时间窗里，针对SSB的子载波间隔为30kHz，定义20个候选位置，针对SSB的子载波间隔为15kHz，定义10个候选位置。发送的SSB的最大个数为Q，基站根据该DRS传输窗内的LBT的检测结果来确定使用多个候选位置中的Q个候选位置来传输DRS。其中，该参数Q可以由网络设备为终端设备配置，或者也可以为协议规定的，本申请实施例并不限于此。
图4示出了在候选位置处进行LBT的示意图。如图4所示，这里以子载波间隔为30kHz，定义20个候选位置为例进行说明，发送的SSB的最大个数Q取8，对应的，该8个SSB的可能起始位置可以为图4中20个候选位置中的任意一个。这里假设基站仅在如图4所示的候选位置索引为1、4、8和16进行LBT，也就是将这四个位置作为8个SSB的可能起始位置。如图4所示，假设基站在候选位置12之前进行的LBT成功，则对应开始发送SSB QCL index 0-7。
其中，NR-U中的SSB QCL index与NR中的SSB index含义是不同。在NR中，SSB index可以用于获得同步和QCL关系，而NR-U中，通过SSB position index获得同步，通过SSB QCL index获得QCL关系。
如图4所示，根据LBT成功的时刻，SSB的实际发送位置可能在20个候选位置中任何一个或多个。对于NR-U中定义的SSB的发送方式，由于UE需要通过在候选发送位置上接收到的SSB获得帧同步，需要针对候选发送位置定义SSB position index。例如，以最大SSB的发送个数Q＝8，候选位置个数Y＝20为例，由于最大8个SSB可能在20个候选位置上发送，SSB携带的SSB position index需要扩展到0到19，以便UE获得接收到的SSB的位置，进一步获得帧同步。而由于最大的SSB发送个数为8，用于获得SSB之间的QCL关系的SSB QCL index的取值范围为0到7，也就是SSB position index与SSB QCL index的取值范围不相同。对于不同时刻发送的SSB，如果它们的SSB QCL index相同，则认为它们之间是有QCL关系的。换句话说，SSB QCL index不相同的SSB之间不存在QCL关系。其中，SSB QCL index＝Mod(SSB position index，Q)，SSB QCL index的取值范围为0到Q-1。
图5示出了具有不同位置索引的SSB的准共址关系。如图5所示，假设发送SSB的候选位置有20个，位置索引的取值范围为0-19，而最大的SSB发送个数为8，也就是用于获得SSB之间的QCL关系的SSB QCL index的取值范围为0到7，那么可能存在多个SSB的位置索引不同，但具有QCL关系。例如，如图5所示，SSB position index为0,8,16的三个SSB均具有QCL关系。
四、信道/信号之间的空间关系信息
在NR***中，UE的信道/信号的发送和接收具有空间特性。网络侧为UE配置了信道/信号之间的空间关系信息，以指示上行物理上行控制信道(Physical Uplink Control Channel，PUCCH)或探测信号(Sounding Reference Signal，SRS)与参考信号之间的空间关系信息，其中，该参考信号可以是SSB、信道状态信息参考信号(Channel-State Information Reference Signal，CSI-RS)或者SRS。例如，当网络侧指示PUCCH与SSB之间具有空间关系时，UE则可以使用与接收该SSB相同的空间域滤波器，来发送PUCCH。再例如，当网络侧指示目标SRS与SSB之间具有空间关系时，UE将使用与接收该SSB相同的空间域滤波器，来发送目标SRS。
在NR中，网络侧配置的上行信道/信号与参考信号的空间关系信息中，SSB是通过SSB-Index进行标识的；SSB-Index的取值范围是0到L-1，在SSB中携带，且具有不同的SSB-Index的SSB不具有QCL关系，通过SSB-Index可以直接获得该SSB的QCL关系。
而在NR-U中，SSB中携带的是SSB position index，而QCL关系的获得是通过SSB QCL index，而SSB QCL index并不是SSB中直接携带的，而是通过SSB position index和参数Q计算得到的。因此，在NR-U中，若SSB与上行信道/信号具有空间关系时，如何标识该SSB是目前需要解决的问题。本申请实施例提出了一种用于发送上行信道/信号的方法，能够解决该问题。
图6为本申请实施例提供的一种用于发送上行信道/信号的方法200的示意性流程图。如图6所示，该方法200包括：S210，发送空间关系指示信息。具体地，网络设备向终端设备发送空间关系指示信息，该空间关系指示信息指示了与上行信道/信号存在空 间关系的参考信号。
应理解，本申请实施例的方法200可以用于免授权频谱，例如，该方法可以应用于NR-U***中，但本申请实施例并不限于此。另外，该方法200可以由终端设备和网络设备执行，例如，该终端设备可以为如图1所示的终端设备；该网络设备可以为如图1所示的网络设备。
可选地，本申请实施例中的上行信道/信号可以包括PUCCH和/或SRS。
可选地，本申请实施例中的该空间关系指示信息指示的参考信号可以包括以下至少一个：SSB、CSI-RS和SRS。其中，本申请实施例中的SSB为SS/PBCH block。
应理解，本申请实施例中以该参考信号为SSB为例进行说明，也就是说，网络设备发送的空间关系指示信息指示了与上行信道/信号存在空间关系的SSB，为了区别，这里称该SSB为目标SSB，该目标SSB可以指任意一个SSB。
具体地，该空间关系指示信息用于指示目标SSB，以便于终端设备根据该空间关系指示信息确定目标SSB。其中，该空间关系指示信息可以包括该目标SSB的位置信息，例如，该目标SSB的位置信息可以包括该目标SSB的位置索引；或者，该空间关系指示信息可以包括该目标SSB的准共址(QCL)信息，例如，该目标SSB的QCL信息可以包括该目标SSB的QCL索引。
可选地，作为一个实施例，对于该空间关系指示信息包括该目标SSB的位置信息的情况，例如，该目标SSB的位置信息可以包括该目标SSB的位置索引(position index)，该目标SSB的position index用于表示该目标SSB的发送位置的索引，则终端设备根据空间关系指示信息中的目标SSB的位置索引，确定对应的目标SSB。
其中，目标SSB的位置索引的取值范围表示该目标SSB的可能的发送位置。例如，该目标SSB的position index的取值范围可以与DRS的传输窗口大小有关，该DRS包括该目标SSB；和/或，该目标SSB的position index的取值范围还可以与子载波间隔有关。
例如，以图4为例，DRS窗口大小为5ms，SSB的子载波间隔为30kHz，则SSB可能的发送位置的数量为20，也就是说目标SSB的position index的取值范围为0-19。再例如，DRS窗口大小为5ms，SSB的子载波间隔为15kHz，则定义10个候选位置，即SSB可能的发送位置的数量为10，也就是说目标SSB的position index的取值范围为0-9。网络设备可以采用LBT的方式，在例如上述的20或者10个可能的发送位置中选择一个或者多个，以发送一个或者多个目标SSB，而该空间关系指示信息中包括的目标SSB的position index可以表示该目标SSB实际发送所在位置的索引，以便于终端设备可以确定该目标SSB的位置索引，还可以接收该目标SSB。
可选地，作为另一实施例，对于该空间关系指示信息为该目标SSB的QCL信息的情况，例如，该目标SSB的QCL信息可以包括该目标SSB的QCL索引(QCL index)，该目标SSB的QCL信息或者目标SSB的QCL index可以用于表示该目标SSB与其他SSB之间的QCL关系，例如，具有QCL关系的多个SSB具有相同的QCL索引，相反的，具有不同QCL索引的SSB之间不具有QCL关系。
其中，目标SSB的QCL index的取值范围与一个DRS传输窗口内发送的，不具有QCL关系的SSB的最大个数Q有关，例如，该目标SSB的QCL index的取值范围为0至Q-1。
如图6所示，该方法200还可以包括：S220，确定与上行信道/信号具有空间关系的SSB。具体地，终端设备根据空间关系指示信息，确定与上行信道/信号具有空间关系的目标SSB，并确定该目标SSB对应的目标空间关系信息。
可选地，作为一个实施例，若空间关系指示信息包括该目标SSB的位置信息，例如，该目标SSB的位置信息可以包括该目标SSB的位置索引，则终端设备可以根据该目标SSB的位置索引，确定与之对应的目标空间关系信息。
应理解，对于该目标SSB的位置索引，存在至少一个SSB的位置索引与该目标SSB 的位置索引不同，但是该目标SSB与该至少一个SSB对应于相同的空间关系信息，该目标SSB与该至少一个SSB具有QCL关系，也就是说与目标SSB具有QCL关系的至少一个SSB也对应于目标空间关系信息。
例如，该终端设备可以根据SSB的位置索引与空间关系信息之间的对应关系，确定该目标SSB的位置索引对应的空间关系信息为目标空间关系信息。其中，在该SSB的位置索引与空间关系信息之间的对应关系中，存在具有QCL关系的多个SSB的位置索引对应相同的空间关系信息，也就是说，具有QCL关系的多个SSB的位置索引可能不同，但是该多个SSB对应了相同的空间关系信息。
再例如，该终端设备还可以根据该目标SSB的位置索引，确定该目标SSB的QCL信息，再确定与该目标SSB的QCL信息对应的空间关系信息为目标空间关系信息，例如，终端设备可以根据SSB的QCL信息与空间关系信息之间的对应关系，确定该目标SSB的QCL信息对应的空间关系信息为目标空间关系信息。
应理解，SSB的位置索引可以用于确定SSB的准共址索引。以目标SSB为例，目标SSB的position index与目标SSB的QCL index之间的关系与参数Q有关，也就是说SSB QCL index是根据SSB position index计算得到的。具体地，终端设备可以根据下面的公式(1)，确定该目标SSB的准共址索引：
QCL＝mod(P，Q)        (1)
其中，QCL为该目标SSB的准共址索引，P为该目标SSB的位置索引，Q为用于确定该目标SSB的准共址索引的参数，例如，该Q可以表示一个DRS的传输窗口内发送的不具有准共址关系的SSB的最大个数。可选地，该参数Q可以是由网络设备为终端设备配置的，或者也可以是协议规定的，本申请实施例并不限于此。
根据公式(1)可知，对于不同的SSB position index，可能存在不同的SSB position index对应的多个SSB具有相同的QCL准共址索引，也就是说不同的SSB position index对应的多个SSB彼此之间具有QCL关系的。例如，可以将SSB position index的全部取值范围看作一个集合，该集合可以分为多个子集，同一个子集中包含的SSB的position index不同但具有QCL关系，也就是同一个子集内的SSB具有相同的QCL信息；而属于不同子集的SSB的position index不同并且彼此之间不具有QCL关系，也就是不同子集的SSB的QCL信息不同。
可选地，所为另一个实施例，若空间关系指示信息包括该目标SSB的QCL信息，例如，该目标SSB的QCL信息可以包括该目标SSB的QCL索引，则终端设备可以根据该目标SSB的QCL索引，确定与之对应的目标空间关系信息。
应理解，对于该目标SSB的QCL信息，例如，以QCL索引为例，相同QCL索引的多个SSB具有QCL关系，而不同QCL索引的多个SSB不具有QCL关系。另外，具有相同QCL索引的多个SSB的位置索引可能相同，也可能不同，也就是可能存在至少一个SSB的位置索引与该目标SSB的位置索引不同，但是该目标SSB与该至少一个SSB具有QCL关系，具有相同的QCL信息。并且，具有相同QCL索引的SSB对应于相同的空间关系信息，也就是说与目标SSB具有QCL关系的至少一个SSB也对应于目标空间关系信息。
例如，该终端设备可以根据SSB的QCL信息与空间关系信息之间的对应关系，确定该目标SSB的QCL信息对应的空间关系信息为目标空间关系信息。其中，在该SSB的QCL信息与空间关系信息之间的对应关系中，具有相同QCL信息的SSB具有QCL关系，而具有QCL关系的SSB对应相同的空间关系信息。
再例如，该终端设备还可以根据SSB的位置索引与空间关系信息之间的对应关系，确定出SSB的QCL信息与空间关系信息之间的对应关系；终端设备可以再根据SSB的QCL信息与空间关系信息之间的对应关系，确定该目标SSB的QCL信息对应的空间关系信息为目标空间关系信息。在该SSB的位置索引与空间关系信息之间的对应关系中， 存在具有QCL关系的多个SSB的位置索引对应相同的空间关系信息，也就是说，具有QCL关系的多个SSB的位置索引可能不同，但是该多个SSB的位置索引对应相同的QCL信息，也对应了相同的空间关系信息。
应理解，SSB的位置索引可以用于确定SSB的QCL索引。例如，根据上一个实施例可知，根据上述公式(1)，可以确定任意一个SSB的位置索引对应的QCL索引，为了简洁，在此不再赘述。
可选地，如图6所示，该方法200还可以包括：S230，发送上行信道/信号。具体地，终端设备接收空间关系指示信息，根据该空间关系指示信息确定目标SSB，并确定该目标SSB的目标空间关系信息，以便于该终端设备将该目标空间关系信息确定为发送上行信道/信号的空间关系信息。也就是说，该目标空间关系信息用于确定上行信道/信号的发射的空间特性，以便于终端设备根据空间关系信息确定的空间特性，发送上行信道/信号。
例如，当网络设备通过空间关系指示PUCCH与目标SSB之间具有空间关系时，终端设备确定该目标SSB对应的空间关系信息与PUCCH相同，则终端设备可以使用与接收该目标SSB相同的空间域滤波器，来发送该PUCCH。
再例如，当网络设备通过空间关系指示SRS与目标SSB之间具有空间关系时，终端设备确定该目标SSB对应的空间关系信息与SRS相同，则终端设备可以使用与接收该目标SSB相同的空间域滤波器，来发送该SRS。
因此，本申请实施例的用于发送上行信道/信号的方法，终端设备接收网络设备发送的空间关系指示信息，该空间关系指示信息可以包括SSB的位置信息或者SSB的QCL信息，以便于终端设备正确的确定该SSB并确定该SSB的空间特性，从而根据该空间特性发送上行信道/信号，例如发送PUCCH或SRS，提高PUCCH或SRS的接收性能。
应理解，在本申请的各种实施例中，上述各过程的序号的大小并不意味着执行顺序的先后，各过程的执行顺序应以其功能和内在逻辑确定，而不应对本申请实施例的实施过程构成任何限定。
