具体实施方式
下面结合附图和实施例对本申请进行说明。此处所描述的实施例仅仅用于解释本申请，而非对本申请的限定。另外，为了便于描述，附图中仅示出了与本申请相关的部分而非全部结构。
在NTN和多切换的场景中，卫星基站距离地面终端非常远，导致传输时延大，对于LEO卫星基站，高达7.5km/s的运动速度还会使终端发生频繁切换。过大的时延导致随机接入过程持续时间长、受信道变化的影响大，而频繁的切换导致频繁的随机接入过程。在NR协议中，并没有在随机接入过程中加入CSI上报的机制，服务节点在做出竞争解决的决策时，由于缺乏信道状态信息的考虑而导致随机接入过程中的传输性能大大受损，无法适应信道变化。
本实施例针对随机接入引入CSI的上报机制，终端向服务节点上报CSI，服务节点可以根据终端上报的CSI在竞争的终端中选择最佳的接入终端或者确定调制方式等，从而更好地适应无线信道的变化，提高随机接入的性能。
图1为一实施例提供的一种信息上报方法的流程图。本实施例提供的信息上报方法可应用于终端，如图1所示，该方法包括步骤110和步骤120。
在步骤110中，接收随机接入机制下的指示信息。
在一实施例中，终端接收服务节点在随机接入机制下发送的指示信息，服务节点可以通过随机接入响应消息(Random Access Response，RAR)或下行广播消息指示终端上报CSI。在一实施例中，指示信息还可用于指示终端上报CSI的参数、计算CSI所需测量的参考信号等。
在步骤120中，根据所述指示信息上报信道状态信息。
在一实施例中，终端根据指示信息，通过测量参考信号得到对应的信道状态信息并上报给服务节点。例如，指示信息可以指示终端对同步信号/物理广播 信道块(Synchronization Signal/Physical Broadcast Channel Block，SSB)进行测量并上报最佳参考信号的接收功率，这种情况下，终端在接收到指示信息后，测量SSB并确定最佳SSB的接收功率，作为CSI上报给服务节点。又如，指示信息可以指示终端对信道状态信息参考信号(Channel State Information Reference Signal，CSI-RS)进行测量并上报最佳CSI-RS的信道质量指示(Channel Quality Indicator，CQI)，则终端在接收到指示信息后，测量CSI-RS并确定最佳CSI-RS的CQI，作为CSI上报给服务节点。在此基础上，服务节点可以根据终端上报的CSI做出随机接入的决策，向终端发送竞争解决消息。
在一实施例中，终端上报CSI的资源位置与终端的标识(Identifier，ID)相对应；在终端接收并测量多个基站的下行参考信号的情况下，资源位置还与小区的ID相对应。
在一实施例中，上报CSI的参数可根据实际情况设置。例如可以根据天线端口数、高层参数配置等设置。例如，指示信息中可以包括CQI的指示信息，用于指示终端上报宽带CQI或子带CQI。又如，指示信息中可以包括预编码矩阵指示(Precoding Matrix Indicator，PMI)的指示信息，用于指示终端在天线端口数大于1的情况下上报宽带PMI还是子带PMI；在上报子带PMI的情况下，在端口数不为2的情况下还可以指示终端上报一个宽带PMI(i1)并且每个子带上报一个子带PMI(i2)，在端口数为2的情况下，还可以指示终端每个子带上报一个子带PMI；在上报了PMI的情况下，还可以指示终端上报层指示(Layer Indicator，LI)来指示预编码矩阵中对应码字最强层的列等。上述的CQI、PMI、LI等都做CSI上报，供服务节点决策。
在一实施例中，指示信息用于指示终端通过第一类随机接入机制的第三消息上报信道状态信息；或者，指示信息用于指示终端通过第二类随机接入机制的A类消息上报信道状态信息。
在一实施例中，在第一类随机接入机制的情况下，所述指示信息为随机接入响应消息RAR或下行广播消息；在第二类随机接入机制的情况下，所述指示信息为下行广播消息。
图2为一实施例中的第一类随机接入机制的示意图。如图2所示，在第一类随机接入机制中，在终端与服务节点建立连接前有四个步骤：
1)终端向服务节点发送第一消息(记为msg1(message1))，msg1中包括随机接入前导，用于向服务节点发起竞争接入的请求，随机接入前导一致的终端之间存在竞争关系。
2)服务节点接收到msg1后，向终端发送第二消息(记为msg2(message2))，msg2为RAR，用于响应终端发起的竞争接入的请求。
3)终端向服务节点发送第三消息(记为msg3(message3))，用于根据服务节点的指示信息上报CSI，指示信息可以为RAR，也可以为下行广播消息，下行广播消息在步骤1)之前由服务节点向终端发送。
4)服务节点向终端发送第四消息，第四消息包括竞争解决消息，表示服务节点根据CSI做出的竞争解决方案。
在第一类随机接入机制的场景下，指示信息用于指示终端通过msg3上报CSI。
图3为一实施例中的第二类随机接入机制的示意图。如图3所示，在第二类随机接入机制中，在终端与服务节点建立连接前有两个步骤：
1)终端根据指示信息向服务节点发送A类消息(记为msgA(messageA))，msgA中包括随机接入前导以及CSI，从而发起竞争接入请求，并上报CSI。指示信息为下行广播消息，下行广播消息在步骤1)之前由服务节点向终端发送。
2)服务节点接收到msgA后，向终端发送B类消息(记为msgB(messageB))，msgB中包括RAR以及竞争解决消息，从而响应终端发起的竞争接入请求，并指示根据CSI做出的竞争解决方案。
在第二类随机接入机制的场景下，指示信息用于指示终端通过msgA上报CSI。
在一实施例中，所述指示信息包括以下至少之一：第一指示信息，用于指示终端上报的信道状态信息所包括的参数；第二指示信息，用于指示终端计算信道状态信息所需测量的参考信号；第三指示信息，用于指示终端对信道状态信息的上报操作，所述上报操作包括上报和不上报。
本实施例中，第一指示信息可用于指示终端上报的CSI中所包括的参数，例如，最佳参考信号的索引、参考信号接收功率(Reference Signal Receiving  Power，RSRP)、CQI、PIMI、秩指示(Rank indicator，RI)等；第二指示信息可用于指示终端通过测量SSB计算CSI，或者通过测量CSI-RS计算CSI；第三指示信息用于指示终端是否需要上报CSI。
在一实施例中，在指示信息不包括一项信息的情况下，可根据预设规则确定相应的指示内容。例如，在指示信息不包括第一指示信息的情况下，终端和服务节点之间可以预先约定、通过协议规定或者通过其他信令通知的方式，指示出上报的CSI默认包括哪些参数，终端在上报CSI的过程中上报这些参数即可。
在一实施例中，在指示信息不包括第二指示信息且在第一类随机接入机制的情况下，终端计算CSI所需测量的参考信号为第一类随机接入机制中的第一消息所占资源对应的参考信号；或者，在指示信息不包括第二指示信息且在第二类随机接入机制的情况下，终端计算CSI所需测量的参考信号为第二类随机接入机制的A类消息所占资源对应的参考信号；其中，参考信号包括SSB和CSI-RS中的至少之一。
本实施例中，对于第一类随机接入机制，指示信息不包括第二指示信息的情况，终端通过测量第一消息所占的资源对应的参考信号得到CSI，第一消息所占的资源为物理随机接入信道(Physical Random Access Channel，PRACH)；对于第二类随机接入机制，指示信息不包括第二指示信息的情况，终端测量A类消息所占的资源对应的参考信号得到CSI，A类消息所占的资源为PRACH和物理上行共享信道(Physical Uplink Shared Channel，PUSCH)。
在一实施例中，信道状态信息通过测量参考信号得到，参考信号包括SSB和CSI-RS中的至少之一。
在一实施例中，信道状态信息的参数包括最佳参考信号的索引、RSRP、CQI、RI、PMI中的至少之一。
在一实施例中，信道状态信息的参数包括最佳参考信号的索引；或者，在最佳参考信号的索引与用于发射第一类随机接入机制的第一消息或第二类随机接入机制的A类消息所占资源对应的参考信号的索引一致的情况下，信道状态信息的参数不包括最佳参考信号的索引，在最佳参考信号的索引与用于发射第一类随机接入机制的第一消息或第二类随机接入机制的A类消息所占资源对应 的参考信号的索引不一致的情况下，信道状态信息的参数包括最佳参考信号的索引。
在一实施例中，在参考信号天线端口数为1的情况下，所述信道状态信息的参数不包括PMI和RI；或者，在参考信号天线端口数大于1的情况下，所述信道状态信息的参数包括最佳参考信号的索引、参考信号接收功率RSRP、信道状态指示CQI、秩指示RI、预编码矩阵指示PMI中的至少之一。
本实施例中，在参考信号天线端口数为1的情况下，无需区分秩和预编码矩阵，因此，上报的CSI的参数可以不包括PMI和RI，但包括最佳参考信号的索引、RSRP、CQI中的至少之一。或者，在参考信号天线端口数大于1的情况下，CSI的参数包括最佳参考信号的索引、RSRP、CQI、RI、PMI中的至少之一。
在一实施例中，最佳参考信号为测量功率最大的参考信号或CQI最大的参考信号。
本实施例中，参考信号可以为SSB和CSI-RS，对参考信号进行测量，将接收功率最大的参考信号作为最佳参考信号，或者将CQI最大的参考信号作为最佳参考信号，并上报最佳参考信号的CSI，CSI可以包括最佳参考信号的索引、RSRP、CQI、RI、PMI中的至少之一。
在一实施例中，在根据指示信息上报信道状态信息之后，还包括：接收服务节点根据信道状态信息生成的竞争解决消息；在竞争解决消息中的终端ID与上报CSI的终端ID一致的情况下，与服务节点建立连接。
