具体实施方式
为使本申请实施例的目的、技术方案和优点更加清楚，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，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作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。
为了便于清楚描述本申请实施例的技术方案，在本申请的各实施例中，若采用了“第一”、“第二”等字样对功能和作用基本相同的相同项或相似项进行区分，本领域技术人员可以理解“第一”、“第二”等字样并不对数量和执行次序进行限定。
在NR系统中，上行信道包括PUSCH和PUCCH。
目前，对于高频传输，由于传输范围受限，通常上行信道会经过波束赋形后进行传输以增强覆盖。为了确定赋形波束的方向，需要进行上行或者下行的参考信号波束扫描，选择波束质量好的参考信号，基于此参考信号的波束确定上行信道传输的波束。
比如：对于PUCCH，基站选择的上行信道传输使用的波束是通过空间关系信息(SpatialRelationInfo)半静态的直接配置给终端的；
对于PUSCH，基站选择的上行信道传输使用的波束是由动态信令DCI(Downlink Control Information，下行控制信息)中SRI(Sounding Reference Signal Resource Indicator，信道探测参考信号资源指示)所指的SRS(Sounding Reference Signal，信道探测参考信号)资源的空间关系信息(SpatialRelationInfo)间接指示的。
但是，PUSCH传输的波束虽然可以动态指示，但只能由参考信号的波束确定；而PUCCH传输的波束只能半静态配置，无法动态改变，从而限制了上行信道传输使用的波束的灵活选择。
针对上述问题，本申请实施例提供一种上行信道传输方法、装置、基站、终端及存储介质，以提高上行信道传输使用的波束的灵活选择。
本申请实施例提供的上行信道传输方法、装置、基站、终端及存储介质可以应用在无线通信系统或无线与有线结合的系统。包括但不限于5G系统(如NR系统)、6G系统、卫星系统、车联网系统、演进型长期演进(Long Term Evolution，LTE)系统，上述系统的后续演进通信系统等。
本申请实施例提供的基站可以包含但不限于以下中的一种或多种：通常 所用的基站、演进型基站(evolved node base station，eNB)、5G系统中的网络侧设备(例如下一代基站(next generation node base station，gNB)、发送和接收点(transmission and reception point，TRP))等设备。
本申请实施例提供的终端有可以被称为用户设备等。终端包括单不限于手持设备、车载设备。例如，可以为手机、平板电脑、笔记本电脑、超级移动个人计算机(Ultra-Mobile Personal Computer，UMPC)、上网本或者个人数字助理(Personal Digital Assistant，PDA)等。
下面通过具体实施例进行说明。
图1为本申请实施例提供的一种上行信道传输方法的流程图，该上行信道传输方法可以用于终端。如图1所示，该上行信道传输方法包括如下步骤：
步骤110：确定上行波束或下行波束。
具体地，上行波束可以通过上行波束管理来获得，并用于进行下行数据传输。其中，上行波束可以包括但不限于以下一项或多项：
最近的RACH(Random Access Channel，随机接入信道)的波束；
预定义的PUSCH的波束；
上行PUCCH信道使用的波束。
其中，最近的RACH可以指的是终端在确定上行信道传输使用的第一波束之前的最后一个RACH。
另外，下行波束可以通过下行波束管理来获得，并用于进行下行传输。其中，下行波束可以包括但不限于以下一项或多项：
下行PDCCH(Physical Downlink Control Channel，物理下行控制信道)的波束；
下行CORESET(Control-resource set，控制资源集)的波束；
下行PDSCH(Physical Downlink Shared Channel，物理下行共享信道)中的DMRS(Demodulation Reference Signal，解调参考信号)的波束；
终端最近一次CRI(Channel State Information-Reference Signal resource indicator，信道状态信息参考信号资源指示)上报中的参考信号的波束；
用于确定下行PDSCH中的SRS的波束；
下行PDSCH信道使用的波束。
其中，最近一次CRI上报可以指的是终端在确定上行信道传输使用的第一波束之前的最后一次CRI上报。
步骤120：根据上行波束或下行波束、以及设定规则或基站为终端配置的第一指示信息，确定上行信道传输使用的第一波束。
具体地，终端可以根据设定规则从上行波束或下行波束中确定上行信道传输使用的第一波束，也可以根据基站为终端配置的用于波束管理的第一指示信息从上行波束或下行波束中确定上行信道传输使用的第一波束。
其中，设定规则可以是系统预先定义的规则。
第一指示信息可以是基站通过动态指令指示给终端的。
上行信道可以包括PUSCH和PUCCH中的至少一个。
步骤130：使用第一波束发送上行信道。
由上述实施例可见，在确定上行波束或下行波束后，可以结合设定规则或基站为终端配置的第一指示信息从上行波束或下行波束中来确定上行信道传输使用的第一波束，以及使用该第一波束发送上行信道，从而提高了上行信道传输使用的波束的灵活选择，还提高了上行信道传输的效率。
进一步地，建立在上述方法的基础上，上述步骤120中的设定规则中包括多个子规则；基站为终端配置的第二指示信息中包括用于指示所述子规则生效的标识。
与此对应的，在执行步骤120中根据上行波束或下行波束、以及设定规则确定上行信道传输使用的第一波束时，可以先获取基站为终端配置的第二指示信息，所述第二指示信息中包括用于指示所述子规则生效的标识；再根据所述设定规则和所述第二指示信息，从所述上行波束或下行波束中确定上行信道传输使用的第一波束。
具体地，基站可以通过高层信令或物理层信令指示设定规则中生效的子规则。
比如：终端根据第二指示信息确定设定规则中生效的子规则，并根据该生效的子规则确定上行信道传输使用的第一波束。
由上述实施例可见，在确定上行波束或下行波束后，可以结合设定规则和基站为终端配置的第二指示信息从上行波束或下行波束中来确定上行信道传输使用的第一波束，以及使用该第一波束发送上行信道，从而丰富了确定第一波束的选择方式，提高了上行信道传输的可靠性。
进一步地，建立在上述方法的基础上，上述步骤120中的上行信道可以包括第一PUSCH，上行信道传输使用的第一波束中包括该第一PUSCH传输使用的第二波束。
与此对应的，在执行步骤120时：
可以根据设定规则从上行波束或下行波束中确定第一PUSCH传输使用的第二波束；或
可以根据基站为终端配置的用于波束管理的第一指示信息，从上行波束或下行波束中确定第一PUSCH传输使用的第二波束；或
可以根据设定规则和第二指示信息，从上行波束或下行波束中确定第一PUSCH传输使用的第二波束；其中，设定规则中包括多个子规则，基站为终端配置的第二指示信息中包括用于指示所述子规则生效的标识。

在一实施例中，基站通过RRC(Radio Resource Control，无线资源控制)配置SRS资源1的空间关系信息(SpatialRelationInfo)为CORESET1，此配置说明终端使用接收CORESET1的接收波束用于传输SRS资源1。类似的，基站配置SRS资源2的空间关系信息(SpatialRelationInfo)为CORESET2，SRS资源3的空间关系信息(SpatialRelationInfo)为CORESET3。经过上行SRS波束扫描后，在时刻n，基站传输的DCI信令中的SRI域指示SRS资源1，指示与SRS资源1使用相同的波束传输PUSCH。在时刻n+K，基站传输DCI信令的SRI域指示SRS资源3，这样终端将与SRS资源3使用相同的波束，即将接收CORESET3的接收波束确定为n+K时刻的第二波束，并利用 该第二波束发送对应的PUSCH，从而实现了通过DCI的不同指示信息来改变上行波束。
类似的，所述的空间关系信息(SpatialRelationInfo)也可以是下行DMRS信号、下行PDSCH信道、上行PUCCH信道等。
