具体实施方式
下文中将结合附图对本申请的实施例进行说明。
第五代移动通信系统新空口技术(New Radio，NR)的关键特征之一就是支持高频段。高频段有丰富的频域资源，但是存在无线信号衰减快导致覆盖小的问题。波束方式发送信号可以将能量聚集在比较小的空间范围，改善高频段信号的覆盖问题。在波束场景下，随着时间和位置的变化，基站与终端(User Equipment，UE)之间的波束对也可能发生变化，因此需要灵活的波束更新机制。为了支持灵活的波束变化，会导致信令开销变大。
波束可以是一种资源。例如，发送端空间滤波器、接收端空间滤波器、发送端预编码、接收端预编码、天线端口、天线权重矢量或天线权重矩阵等均可以作为波束。波束可以是一种传输的发送或接收方式，包括以下方式中的至少之一：空分复用或频域/时域分集等。
传输的波束或发送方式可以用参考信号资源索引，或空间关系索引指示。一个传输的波束或发送方式或接收方式根据参考信号资源索引确定，是指该传输的发送或接收滤波器参数与参考信号资源索引所指示的参考信号资源的发送或接收滤波器参数相同。所述传输包括以下之一：PUSCH传输、PUCCH传输或SRS传输。空间关系本质上是用参考信号指示，即空间关系索引也可以是参考信号索引。
传输的波束或发送方式或接收方式根据参考信号资源索引确定，是指该传输的解调参考信号与参考信号资源索引所指示的参考信号具有相同的准共址参数。准共址的参数包括以下至少之一：多普勒扩展、多普勒平移、时延拓展、平均时延、平均增益和空间参数。空间参数包括空间接收参数，例如到达角、接收波束的空间相关性、平均时延和时频信道响应的相关性(包括相位信息)。所述传输包括以下之一：物理下行共享信道(Physical Downlink Shared Channel，PDSCH)传输、物理下行控制信道(Physical Downlink Control Channel，PDCCH)传输或CSI-RS传输。
参考信号至少包括以下之一：信道状态信息参考信号(Channel State Information Reference Signal，CSI-RS)、信道状态信息干扰测量信号(Channel State Information Interference Measurement Signal，CSI-IM)、解调参考信号(Demodulation Reference Signal，DMRS)、下行解调参考信号(Downlink Demodulation Reference Signal，DL DMRS)、上行解调参考信号(Uplink Demodulation Reference Signal，UL DMRS)、探测参考信号(Sounding Reference  Signal，SRS)、相位追踪参考信号(Phase-Tracking Reference Signals，PTRS)、随机接入信道信号(Random Access Channel，RACH)、同步信号(Synchronization Signal，SS)、同步信号块(Synchronization Signal Block，SSB)、主同步信号(Primary Synchronization Signal，PSS)或辅同步信号(Secondary Synchronization Signal，SSS)。
可以由高层信令，如RRC(Radio Resources Control，无线资源控制)信令，配置参考信号。例如，下行链路方向(DL)的参考信号是SSB、CSI-RS，上行链路方向(UL)的参考信号是SRS。基站调度DL的传输，如PDSCH、PDCCH或CSI-RS传输，用参考信号指示给UE所调度传输的波束方向或接收方式，则被调度的传输与所指示的参考信号具有相同的准共址参数。基站调度UL的传输，如PUSCH、PUCCH或SRS传输，用参考信号指示给UE所调度传输的波束方向或发送方式，则被调度的传输与所指示的参考信号具有相同的滤波器参数，或具有相同的准共址参数。
下面以UL传输为例介绍。
基站配置至少一个SRS资源(SRS resource)给UE，SRS资源用SRS资源ID(索引或编号，Identifier)区分。基站还配置至少一个SRS资源集合(SRS resource set)给UE，SRS资源集合用SRS资源集合ID(索引或编号)区分。SRS资源集合中包括至少一个SRS资源(SRS resource)。SRS资源集合有不同用途：波束管理、天线选择、码本或非码本。其中，用途为码本和非码本的SRS资源集合分别用于基于码本的PUSCH传输和非基于码本的PUSCH传输。SRS资源中可能配置空间关系。当SRS资源配置了空间关系，UE需要按照SRS资源的空间关系发送SRS资源，即确定发送滤波器参数；当SRS资源没有配置空间关系，则UE自己确定发送滤波器参数。发送滤波器参数可以理解为为了形成特定的波束方向需要的发送参数。
以基站(gNB)和UE都支持多个波束为例说明。一般地，上行和下行链路都需要做波束训练(也叫波束扫描或波束管理)。基站先为UE配置用途为波束管理的SRS资源集合，SRS资源不配置空间关系，UE自己为SRS资源确定发送滤波器参数。然后，基站根据波束训练的结果挑选一些较好的波束对(beam pair)作为可用的/备选的波束对配置用途为码本或非码本的SRS资源集合给UE，SRS资源集合中包括至少一个SRS资源，SRS资源的空间关系用UE已经发送过的SRS资源或基站已经发送过的下行参考信号指示(包括参考信号资源索引)或SSB指示(包括SSB索引)表达，至少一个SRS资源分别对应可用的/备选的至少一个波束对。
对于PUSCH传输，基站通过下行控制信息(Downlink Control Information， DCI)中的SRI(SRS Resource Indicator，SRS资源指示)域指示一个或多个SRS资源，即SRI可以指示多个SRS资源ID。UE则使用与SRI对应的SRS资源相同的发送滤波器参数发送PUSCH，也可以理解为使用相同的波束。DCI中指示的SRI是根据基站配置的SRS资源集合确定的。用途为码本及非码本的SRS资源集合中的SRS资源可以用于PUSCH传输的参考。图2是本申请实施例提供的一种基站和UE在训练后的波束中选择波束进行传输的示意图，图1是本申请实施例提供的一种基站和UE训练后的波束关系示意图，如图1所示，SRS资源集合中包括2个SRS资源，分别标记为SRI1和SRI2。如图2所示，调度PUSCH的DCI中SRI域指示了SRI1，则UE使用SRI1对应的SRS资源的空间关系确定PUSCH的发送滤波器参数。对于PUCCH传输，其波束用PUCCH资源对应的空间关系表达。
对于上行传输，基站还需要为UE配置功控(即功率控制)参数。对PUSCH传输，功控参数与PUSCH的SRI有关联关系。对PUCCH传输，功控参数与PUCCH的空间关系有关联关系。
当UE发生位置改变时，基站与UE之间的可用波束对可能会发生改变。SRS资源集合、SRS资源对应的空间关系，以及DCI中的SRI域的取值与功率控制参数的对应关系都是由高层信令配置的，例如RRC信令。一般地，高层参数的配置时延较大，灵活性不高。因此相关技术支持对SRS资源集合用MAC CE修改SRS资源的空间关系。另外，也支持用MAC CE修改上行传输的功控参数。MAC层介于RRC层之下，物理层之上，其时域和灵活性介于两者之间，对开销的敏感性也介于两者之间。
相关技术使用MAC CE更新上行传输的发送参数时，存在以下问题：
用于空间关系更新的CC group与PL_ref_linking(高层参数pathlossReferenceLinking的取值)、PUCCH group(PUCCH分组)的关系不明确；SRS的空间关系更新的CC group与SRS resource set ID及SRS resource ID的关系不明确；RRC信令对每种上行传输在每个CC的每个BWP独立配置功控参数池导致开销太大。总之，相关技术使用MAC CE确定上行传输的发送参数的机制仍不够完善。
载波聚合(CA，carrier aggregation)或双连接(DC，dual connectivity)场景中包括至少一个CC。CC也可以叫服务小区、小区载波。一个CC可以包括至少一个上行载波，例如UL carrier，SUL carrier，分别表示上行载波、补充的上行载波。一个上行载波或补充的上行载波包括至少一个部分带宽(BWP)。PUSCH传输、PUCCH传输、SRS传输在上行BWP中传输，可以占上行BWP的部分或全部频域资源。
为节省MAC CE的开销，在本申请实施例中，可以使用MAC CE对CC group更新上行信道(PUCCH或PUSCH)或信号(SRS)的空间关系(spatial relation)。
为了解决上述问题，在一个示例性实施方式中，本申请实施例提供了应用于第一节点设备的一种发送参数确定方法。图3是本申请实施例提供的一种发送参数确定流程示意图。该方法可以适用于第一节点设备确定上行传输的发送参数的情况，其中，第一节点设备可以是终端设备等。相应的，如图3所示，本申请提供的一种发送参数确定方法，包括S110。
S110、根据MAC CE确定CC group，以及所述CC group的CC的上行传输的发送参数。
所述上行传输的发送参数包括空间关系信息和/或功控参数信息；所述上行传输包括SRS传输、PUSCH传输及PUCCH传输中的至少一项。
在本申请实施例中，第一节点设备可以接收第二节点设备发送的MAC CE，并根据接收的MAC CE确定CC group，以及CC group内CC的上行传输的发送参数。CC group内CC的上行传输是指CC group内CC的所有BWP或激活的BWP的上行传输。
CC group内CC的上行传输是指每个CC上有指定类型的传输的情形。假设CC group包括CC1、CC2、CC3，其中，CC1上配置PUSCH、PUCCH、SRS传输，而CC2上配置了PUSCH、SRS传输，那么当指定的上行传输是PUCCH传输时，MAC CE应用于CC group中的CC1的PUCCH。而当指定的上行传输是PUSCH传输时，MAC CE应用于CC group中的CC1、CC2、和CC3的PUSCH传输。
本申请实施例通过根据MAC CE确定CC group，以及CC group内所有CC包括空间关系信息和/或功控参数信息的上行传输的发送参数，解决上行传输的发送参数的确定机制不够完善的问题，优化了上行传输的发送参数的确定机制。
在上述实施例的基础上，提出了上述实施例的变型实施例，为了使描述简要，在变型实施例中仅描述与上述实施例的不同之处。
在一个示例中，所述根据MAC CE确定CC group，可以包括：根据所述MAC CE包括的CC group ID，根据所述MAC CE包括的小区编号所属的CC group，或根据承载所述MAC CE的小区所属的CC group，确定所述MAC CE所应用的CC group。
在本申请实施例中，CC group所包括的载波成员(或叫成员载波、服务小区、小区)可以是预先配置的。一个小区只能属于一个CC group，即不同CC group不能有相同的小区。
在一个示例中，所述CC group的特性可以包括下述至少一项：
所述CC group包括至少一个CC；所述CC group的每个CC上都配置了SRS；所述CC group内SRS资源编号相同的SRS资源与相同的空间关系关联；(即，SRS资源所关联的空间关系是相同的参考信号或SSB。)所述CC group内SRS资源编号相同的SRS资源所关联的空间关系的参考信号或SSB具有准共址QCL关系；所述CC group内SRS资源编号相同的SRS资源所关联的空间关系的参考信号或SSB具有相同的类型D的QCL参数；所述CC group包括空间关系CC group和/或功控参数CC group；所述CC group由高层参数配置；所述CC group由路损参考链接参数确定；所述CC group是路损参考链接参数确定的第一类CC group的子集；所述CC group与路损参考链接参数确定的第一类CC group相同；所述CC group由PUCCH分组确定；所述CC group是PUCCH分组的子集；所述CC group与PUCCH分组相同；SRS与PUSCH的所述CC group相同；SRS的空间关系CC group与SRS的功控参数CC group相同；PUSCH的空间关系CC group与PUSCH的功控参数CC group相同。
CC group可以是空间关系和功控参数的CC group，第一类CC group可以是路损参考链接参数确定的CC group。
在本申请实施例中，PUCCH分组可以包括：主PUCCH分组和辅PUCCH分组(Secondary PUCCH group)。主PUCCH分组包括主小区(PCell，Primary Cell)以及大于或等于0个辅小区(SCell，Secondary Cell)，这些小区的PUCCH信令都与PCell上的PUCCH关联。辅PUCCH分组包括一组辅小区，这些辅小区的PUCCH信令都与PUCCH SCell上的PUCCH关联。
在本申请的一个可选实施例中，空间关系的CC group可以是路损参考链接参数确定的CC group或子集。
MAC CE更新SRS的空间关系是基于CC group的。MAC CE更新SRS的空间关系的CC group是RRC配置的，或者由路损参考链接参数(例如，pathlossReferenceLinking参数)确定。MAC CE更新PUSCH传输的空间关系的CC group是RRC配置的，或者可以由路损参考链接参数确定。因此，MAC CE更新上行传输的空间关系的CC group是RRC配置的，或者可以由路损参考链接参数确定。
MAC CE更新上行传输的空间关系的CC group具有如下至少之一的特征：
空间关系的CC group与路损参考链接参数确定的CC group无关；空间关系的CC group与路损参考链接参数确定的CC group相同；或空间关系的CC group的CC成员不多于路损参考链接参数确定的CC group的CC成员。即空间关系 的CC group的CC成员不能属于路损参考链接参数确定的不同CC group。
图4是本申请实施例提供的一种空间关系、CC group与路损参考链接参数确定的第一类CC group的关系示意图。如图4所示，PL_Ref_linking是指高层参数路损参考链接参数的取值。如UL CC1是PCell(primary cell，主小区)，其对应的DL CC为CC1’；DL CC2’、DL CC3’及DL CC4’是UL CC2、UL CC3及UL CC4对应的DL CC。假设UL CC1、UL CC2及UL CC3都参考CC1的PL-RS(路损测量参数)，PL-RS是下行RS在CC1’发送；而UL CC4参考CC4的PL-RS，CC4的PL-RS在CC4’发送。因此路损参考链接参数确定的CC group有两个：CC1+CC2+CC3和CC4。MAC CE更新上行传输的空间关系的CC group中的CC成员依据路损参考链接参数确定的CC group确定，可以是图4中CC group set 1所示的与路损参考链接参数确定的CC group相同，也可以是图4中CC group set 2所示的路损参考链接参数确定的CC group的子集。CC group set 2包括3个CC group：CC1+CC2、CC3及CC4。

上行传输的发送参数中PUSCH传输的功控参数是通过以下方式获得的：
(1)、基站通过高层信令为UE配功控参数池，其中，功控参数池包括以下至少之一：开环功控参数池，闭环功控参数池，路损测量参数池。每个类别 的参数池包括至少一个对应类别的参数。
(2)、基站通过高层信令为UE配SRS资源集合。基站用SRI指示SRS资源集合内的一个或多个SRS资源，用于PUSCH传输的参考。
(3)、基站通过高层信令为UE配置DCI中的SRI域的取值与功控参数池的各个类别的功控参数的关联关系(简称为SRI与功控参数的关联)。另外，基站可以通过MAC CE更新或修改SRI与功控参数的关联。
(4)、基站通过物理层控制信息，如DCI，调度或激活UE发送PUSCH传输，并在DCI中包括SRI域，用于指示PUSCH所参考的SRS资源。或，基站通过高层信令配置UE发送PUSCH传输，并通过高层信令包括SRI指示PUSCH所参考的SRS资源。其中，DCI调度的PUSCH传输称为动态授权的PUSCH传输，高层配置的PUSCH传输称为类型1的配置授权的PUSCH传输，DCI激活的PUSCH传输称为类型2的配置授权的PUSCH传输。
UE接收以上PUSCH传输的功控参数信息，对不同类型的PUSCH传输分为以下几种处理情况：
对于动态授权的PUSCH传输，通过DCI中的SRI值，以及SRI域的取值与功控参数池的各个类别的功控参数的关联关系获取PUSCH传输所对应的功控参数。
对于类型1的配置授权的PUSCH传输，通过高层信令直接获取PUSCH传输的功控参数。
对于类型2的配置授权的PUSCH传输，通过高层信令直接获取PUSCH传输的开环功控参数和闭环功控参数，而路损测量参数则通过激活该PUSCH传输的DCI中的SRI值，以及SRI域的取值与功控参数池的路损测量参数池的关联关系获得。
从上述描述可见，动态授权的PUSCH传输和类型2的配置授权的PUSCH传输的功控参数获取与SRI以及SRI与PUSCH功控参数的关联信息有关。因此，在一些场景中，UE可能无法获得SRI。例如，对类型2的配置授权的PUSCH传输，和动态授权的PUSCH传输，可以用DCI格式0_0或0_1调度或激活。DCI格式0_0中不包括SRI域。当PUSCH传输对应的SRS资源集合中只包括一个SRS资源时，则DCI格式0_1中不包括SRI域。
对动态授权的PUSCH传输，当UE无法获取SRI，或无法获取SRI与PUSCH功控参数的关联信息时，对开环功控参数和闭环功控参数的处理方式为：使用功控参数池中的开环和闭环的功控参数池的编号最小的功控参数。例如开环功控参数池中配置的第一个(编号为0)开环功控参数。对路损测量参数的处理方 式为：当PUCCH的空间参数可以获取时，UE通过最小编号的PUCCH资源的所关联的空间关系获得路损测量参数。当无法获取PUCCH的空间参数时，使用功控参数池中的路损测量参数池的编号最小的功控参数。
对于类型2的配置授权的PUSCH传输，当UE无法获取SRI，或无法获取SRI与PUSCH功控参数的关联信息时，对开环功控参数和闭环功控参数的处理方式为：使用高层参数配置值。对路损测量参数的处理方式为：使用功控参数池中的路损测量参数池的编号最小的功控参数。
综上所述，当UE无法获取SRI，或无法获取SRI与PUSCH功控参数的关联信息时，则使用功控参数池的固定编号的功控参数。
由此可见，MAC CE更新功控参数是更新SRI与PUSCH功控参数的关联ID与功控参数池各类型参数在各自参数池中的ID(包括路损测量参数的ID)的对应关系。这个SRI与PUSCH功控参数的关联ID可以理解为SRI域的取值，当SRI域没有的时候，SRI与PUSCH功控参数的关联ID如何确定，以及没有SRI域时MAC CE更新功控参数无法起效是相关技术存在的问题。例如，SRS resource set中只有1个SRS resource，该SRS resource的空间关系可以通过MAC CE更新，UE无法获得SRI，但是可以通过唯一的SRS resource获得空间关系。基站也可以通过高层信令或MAC CE更新或修改SRI与PUSCH功控参数的关联信息。但上述使用功控参数池的固定编号的功控参数导致基站更新或修改SRI与功控参数的关联无法对PUSCH的传输起效。
因此，当DCI中无SRI域时，RRC或MAC CE更新功控参数时，SRI与PUSCH功控参数的关联信息ID就是固定值，例如0。即相关技术中只有SRI与PUSCH功控参数的关联ID与DCI中的SRI域的取值对应，当DCI中无SRI域时，需要明确SRI与PUSCH功控参数的关联ID就是固定值，例如0。当DCI中无SRI域，但存在SRI与PUSCH功控参数的关联信息时，可以使用SRI与PUSCH功控参数的关联ID中的最大、最小、配置的值、或预定值对应的功控参数。例如0。
