下面结合附图，通过具体的实施例及其应用场景对本申请实施例提供的指示载波信道状态信息的方法进行详细地说明。
如图2所示，本发明的一个实施例提供一种指示载波信道状态信息的方法200，该方法可以由第一终端设备执行，换言之，该方法可以由安装在第一终端设备的软件或硬件来执行，该方法包括如下步骤。
S202：第一终端生成第一MAC CE。
所述第一MAC CE包括侧链路一个或多个载波成分对应的信道状态信息。
其中，第一终端可以生成一个第一MAC CE，该一个第一MAC CE包括 侧链路多个载波成分对应的信道状态信息。
第一终端可以生成多个第一MAC CE，其中的每一个第一MAC CE可以包括一个侧链路多个载波成分对应的信道状态信息，而通过发送多个第一MAC CE发送多个载波成分对应的信道状态信息。
S204：向第二终端发送所述第一MAC CE。
本发明实施例提供的一种指示载波信道状态信息的方法，通过生成第一MAC CE，所述第一MAC CE包括侧链路一个或多个载波成分对应的信道状态信息；向第二终端发送所述第一MAC CE，能够解决SL传输的MAC CE无法表示多个CC对应的CSI的问题。
如图3a所示，本发明的一个实施例提供一种指示载波信道状态信息的方法300，该方法可以由第一终端设备执行，换言之，该方法可以由安装在第一终端设备的软件或硬件来执行，该方法包括如下步骤。
S302：第一终端生成第一MAC CE，所述第一MAC CE包括侧链路一个或多个载波成分对应的信道状态信息，所述侧链路多个载波成分对应的信道状态信息是通过所述第一MAC CE对应的载波成分位图指示的。
本步骤可以采用图2实施例步骤S202的描述，对于重复部分在此不再赘述。
图3b示出第一MAC CE的一种示意图。如图3b所示，在一种实现方式中，所述第一MAC CE包括：信道质量指示(Channel quality indicator，CQI)域和所述第一MAC CE对应的载波成分位图。
在一种实现方式中，所述第一MAC CE对应的载波成分位图中的第一比特用于表示对应的第一载波成分是否有对应的信道状态信息。其中所述信道状态信息包括CQI和RI的至少一项。
比如C0＝1表示对应的SL CC 1有对应的信道状态信息(例如CQI值)，C1＝0表示SL CC 2没有对应的信道状态信息。
在一种实现方式中，所述第一MAC CE中包括多个CQI域，所述CQI 域与表示第一载波成分有对应的信道状态信息的目标比特之间具有一一对应关系，所述目标比特对应的CQI域是通过所述目标比特在所述载波成分位图中的排序指示的。
如图3b所示，比如C0＝1表示对应的SL CC 1有对应的CQI值，C1＝1表示对应的SL CC 2有对应的CQI值，C0、C1为目标比特。
C2＝0表示对应的SL CC 3无对应的CQI值，C2不是目标比特。
C3＝1表示对应的SL CC 4有对应的CQI值，C3为目标比特。
可见，目标比特在所述载波成分位图中的排序为：C0、C1、C3，则通过该排序可以确定：图中第一个八位组Oct1对应的CQI值对应目标比特C0，是C0对应的SL CC 1的CQI值；图中第二个八位组Oct2对应的CQI值对应目标比特C1，是C1对应的SL CC 2的CQI值；第三个八位组Oct3(图中未示出)对应的CQI值对应目标比特C3，是C3对应的SL CC 4的CQI值。
类似地，在一种实现方式中，所述第一MAC CE中还包括多个秩指示(Rank indicator，RI)，所述RI域与表示第一载波成分有对应的信道状态信息的目标比特之间具有一一对应关系，所述目标比特对应的RI域是通过所述目标比特在所述载波成分位图中的排序指示的。
作为一种可选的实施方式，对于位图中指示有信道状态信息的一个或多个CC，该一个或多个CC各自对应的信道状态信息可以基于CC标识以升序的形式进行排列。当然，也可以以降序的形式排列，本实施例不做具体限定。
作为一种可选的实施方式，对于位图中指示有信道状态信息的一个或多个CC，该一个或多个CC中的每个CC对应一个八位组，每个CC对应的一个八位组中包括该CC对应的信道状态信息(例如CQI和/或RI)。
可选地，所述第一MAC CE还可以包括预留比特位R。作为另一种可选的实施方式，对于位图中指示有信道状态信息的CC，每个CC对应一个八位组，每个CC对应的一个八位组中包括预留比特位R。其中，预留比特位的个数不做限定。例如，图3b中的第一个八位组中包括3个bit的预留比特位 R，第二个八位组中也包括3个bit的预留比特位。
需要说明的是，图3b中的MAC CE是以最多可以发送32个CC的信道状态信息进行设计的，C i域具有四个八位组，当然，如果最多可以发送8个CC的信道状态信息，C i域也可具有一个八位组，本实施例不做具体限定。另外，图3b中的MAC CE的信道状态信息所在的一个或多个八位组排在C i域的前面，当然，信道状态信息所在的一个或多个八位组也可排在C i域的后面，本实施例不做具体限定。
S304：向第二终端发送所述第一MAC CE。
本发明实施例提供的一种指示载波信道状态信息的方法，通过生成第一MAC CE，所述第一MAC CE包括侧链路一个或多个载波成分对应的信道状态信息；向第二终端发送所述第一MAC CE，能够解决SL传输的MAC CE无法表示多个CC对应的CSI的问题。
如图4a所示，本发明的一个实施例提供一种指示载波信道状态信息的方法400，该方法可以由第一终端设备执行，换言之，该方法可以由安装在第一终端设备的软件或硬件来执行，该方法包括如下步骤。
S402：第一终端生成第一MAC CE，所述第一MAC CE包括侧链路一个或多个载波成分对应的信道状态信息，所述侧链路多个载波成分对应的信道状态信息是通过所述第一MAC CE对应的载波成分索引指示的。
本步骤可以采用图2实施例步骤S202的描述，对于重复部分在此不再赘述。
图4b-4e示出第一MAC CE的一种示意图。在一种实现方式中，所述第一MAC CE包括第一域和第二域，其中，所述第一域用于指示对应的第二载波成分的索引(例如CC index)，所述第二域用于指示所述索引对应的信道状态信息；其中所述信道状态信息包括CQI和RI的至少一项。
一种可选的实施方式，每个CC对应的第一域和第二域使用一个八位组，例如，图4b中，CC index对应的CC的第一域和第二域使用一个八位组Oct1。
另一种可选的实施方式，每个CC对应的第一域和第二域分布在两个八位组中。可选地，所述第一MAC CE还可以包括预留比特位R。其中，图4c、4d分别示出不同位数的预留比特位R。
作为一种可选的实施方式，信道状态信息基于CC index i以升序的形式进行排列，当然，也可以降序的形式进行排列，本实施例不做具体限定。
在另一种实现方式中，可选地，第一域可以占用现有CSI MAC CE的预留比特位R。如图4e所示，例如，预留比特位R为3位，第一域占用预留比特位R可以指示8个CC索引，其对应关系可以包括：
000->CC1
001->CC2
010->CC3
011->CC4
100->CC5
101->CC6
110->CC7
111->CC8
在一种实现方式中，载波频点与所述第一域指示的载波成分索引之间的对应关系为预配置或基站配置或由第二终端配置。一种实现方式中，所述对应关系通过系统消息或RRC重配置消息传输或侧链路RRC重配置消息传输。
可选地，基站配置CC索引值，包括CC1,CC2,...，CC8对应哪个载波频点，例如包括f1,f2,....,f8。此时，所述对应关系可以通过系统消息或RRC重配置消息传输或侧链路RRC重配置消息传输。
可选地，预配置CC索引值，包括CC1,CC2,...，CC8对应哪个载波频点，例如包括f1,f2,....,f8，此时无需网络与SL UE协商。
可选地，Sidelink RRC配置CC索引值，包括CC1,CC2,...，CC8对应哪个载波频点，例如包括f1,f2,....,f8，此时，SL UE通过Sidelink RRC重配置消息接收来自对端SL UE 2发送的该对应信息。对端SL UE 2发送的该对应 信息可以是自己决定，也可以是来自于它的服务基站配置。
S404：向第二终端发送所述第一MAC CE。
