Description

信道信息的上报和接收方法、终端及网络侧设备
交叉引用
本发明要求在2022年11月04日提交中国专利局、申请号为2022113782849、发明名称为“信道信息的上报和接收方法、终端及网络侧设备”的中国专利申请的优先权，该申请的全部内容通过引用结合在本发明中。
技术领域
本申请属于通信技术领域，具体涉及一种信道信息的上报和接收方法、终端及网络侧设备。
背景技术
由信息论可知，准确的信道状态信息(channel state information，CSI)对信道容量的提升至关重要。尤其是对于多天线系统，发送端可以根据CSI优化信号的发送，使其更加匹配信道的状态，从而可以提升信道容量。
新空口(New Radio，NR)的信道状态信息(或简称信道信息)上报主要包括秩指示(rank indicator，RI)、信道质量指示(channel quality indicator，CQI)、预编码矩阵指示(precoding matrix indicator，PMI)、层指示(layer indicator，LI)以及波束质量等，其中，CQI可以用来选择合适的调制编码方案(modulation and coding scheme，MCS)以实现链路自适应；PMI可以用来实现特征波束成形(eigen beamforming)从而最大化接收信号的强度，或者用来抑制干扰(如小区间干扰、多用户之间干扰等)。因此，自从多天线技术(multi-input multi-output，MIMO)被提出以来，信道信息获取一直都是研究热点。
相关技术中的信道信息上报框架主要是针对单个信道信息的压缩和优化，由于单个信道信息的数据量较小，上报开销较小。随着人工智能(Artificial Intelligence，AI)等融入无线通信网络，终端通常需要上报大量的信道信息，目前对于大量的信道信息的上报尚无研究和优化，信道信息的上报开销较大。

下面结合附图，通过一些实施例及其应用场景对本申请实施例提供的信道信息的上报和接收方法进行详细地说明。
如图2所示，本申请实施例提供一种信道信息的上报方法200，该方法可以由终端执行，换言之，该方法可以由安装在终端的软件或硬件来执行，该方法包括如下步骤。
S202：终端基于第一特征信息对多个第一信道信息进行分组，得到一个或多个分组； 其中，每个分组内的所述第一信道信息共享第二特征信息，所述第二特征信息为所述第一特征信息的部分或全部。
本申请各个实施例中提到的第一信道信息可以是预编码矩阵指示(Pre-coding Matrix Indicator，PMI)，S202之前，终端还可以使用第三代合作伙伴计划(3rd Generation Partnership Project，3GPP)码本对信道H1进行压缩得到第一信道信息(或称PMI1)，该3GPP码本可以包括类型1(Type I)码本，类型2(Type II)码本(包括Type II的增强和演进)或3GPP新型码本等。
本申请各个实施例中提到的第一信道信息可以是终端基于参考信号得到的信道信息，S202之前，终端可以接收或检测参考信号得到第一信道信息。
可选地，所述第一特征信息包括如下至少之一：1)波束信息；2)幅度系数；3)相位系数；4)Type I码本的第一预编码矩阵(W1)；5)Type I码本的第二预编码矩阵(W2)；6)子带数目。
该步骤中提到的多个第一信道信息可以是多个样本的第一信道信息，每个样本可以对应一个第一信道信息，当然也可以对应多个第一信道信息。这些样本的第一信道信息可以用于AI模型训练或输入，该AI模型可以用于指定的通信任务，如信道状态信息压缩和信道预测等。
该步骤中，终端可以将具有相同的第一特征信息的第一信道信息分到一个分组内，每个分组内的所述第一信道信息共享第二特征信息。
例如，第一特征信息包括波束信息和幅度系数，终端依据波束信息和幅度系数对多个第一信道信息进行分组，得到第一分组和第二分组，其中，第一分组内的多个样本均具有相同的波束信息1和幅度系数1，第一分组内的多个样本共享波束信息1和幅度系数1(即第二特征信息，第二特征信息是第一特征信息的全部)；第二分组内的多个样本均具有相同的波束信息2和幅度系数2，第二分组内的多个样本共享波束信息2和幅度系数2(即第二特征信息，第二特征信息是第一特征信息的全部)。
又例如，第一特征信息包括波束信息和幅度系数，终端先依据波束信息对多个第一信道信息进行分组，得到第三分组，第三分组内的样本均具有相同的波束信息3；终端再依据幅度系数对第三分组内的样本进行分组，得到第一子分组和第二子分组，第一子分组内的样本具有相同幅度系数3，第二子分组内的样本具有相同幅度系数4。
该例子中，第三分组内的样本共享波束信息3(即第二特征信息，第二特征信息是第一特征信息的部分，因为第一特征信息还包括幅度系数)。第一子分组内的样本共享波束信息3+幅度系数3，第二子分组内的样本共享波束信息3+幅度系数4。
又例如，第一特征信息为相位系数，终端依据相位系数对多个第一信道信息进行分组，得到第四分组，其中，第四分组内的多个样本等均具有相同的相位系数1(即第二特征信息)，相位系数1是第一特征信息的全部。
可选地，所述每个分组内的所述第一信道信息共享第二特征信息包括如下之一：
1)每个分组的信息中包含所述第二特征信息，分组内的所述第一信道信息不携带所述第二特征信息。
该例子可以在分组的信息中携带共享的第二特征信息，分组内的多个第一信道信息均不携带所述第二特征信息，从而节省了重复第二特征信息的开销。
2)每个分组内的一个所述第一信道信息携带所述第二特征信息，分组内的其他所述第一信道信息不携带所述第二特征信息。
例如，样本X1、X2、X3、….、XN为一个分组，样本X1携带该分组的第二特征信息，样本X2、X3、….、XN均可以不携带该分组的第二特征信息；样本Y1、Y2、Y3、….、YM为一个分组，样本Y1携带该分组的第二特征信息，样本Y2、Y3、….、YM均可以不携带该分组的第二特征信息，从而节省了重复第二特征信息的开销。
S204：所述终端发送所述一个或多个分组的所述第一信道信息。
本申请实施例提供的信道信息的上报方法，终端基于第一特征信息对多个第一信道信息进行分组，每个分组内的第一信道信息可以共享部分或全部的第一特征信息，终端发送分组后的第一信道信息。本申请实施例减少了重复的第一特征信息的开销，从而可以减少信道信息的上报开销，降低通信系统的资源开销和时延。

b、所述终端将包含的至少一个波束相同的第一信道信息分为一个分组。例如，第一信道信息包括第一波束，第二波束，第三波束和第四波束，终端将包含的第一个波束相同的第一信道信息分为一组；此轮分组结束后，在组内根据包含的第二个波束继续进行分组，以此类推。
2)幅度系数，可以包括宽带幅度系数和/或子带幅度系数。

对于上述任意一个分组的多个所述幅度系数是通过差分上报的方式发送的，例如，第 五分组内的样本包括Z1、Z2、Z3、Z4、Z5、Z6，其中，Z1、Z2、Z3、Z4、Z5具有相同的幅度系数1，Z6具有幅度系数2，终端可以上报幅度系数1，幅度系数1作为参考值，幅度系数2是通过差分上报的方式发送的，仅需要上报幅度系数2与幅度系数1的差值。
在一个例子中，所述幅度系数包括宽带幅度系数和子带幅度系数，所述终端基于第一特征信息对多个第一信道信息进行分组包括：所述终端基于所述宽带幅度系数对多个第一信道信息进行分组，得到一个或多个第一分组；所述终端基于所述子带幅度系数对第一分组内的第一信道信息继续进行分组。即，终端先根据宽带幅度系数进行分组，然后根据子带幅度系数进行分组。
3)相位系数，可以包括宽带相位系数和/或子带相位系数。
在一个例子中，所述第一特征信息包括所述相位系数；其中，不同的分组之间的所述相位系数是通过差分上报的方式发送的，或任意一个分组的多个所述相位系数是通过差分上报的方式发送的。
对于上述差分上报的方式，终端可以选择一个分组的相位值作为参考相位值，其它分组的相位值表示为与该参考相位值的差值。通过差分上报的方式，可以进一步节约上报开销。
对于上述任意一个分组的多个所述相位系数是通过差分上报的方式发送的，例如，第六分组内的样本包括K1、K2、K3、K4、K5、K6其中，K1、K2、K3、K4、K5具有相同的相位系数1，K6具有相位系数2，终端可以上报相位系数1，相位系数1作为参考值，相位系数2是通过差分上报的方式发送的，仅需要上报相位系数2与相位系数1的差值。
在一个例子中，所述相位系数包括宽带相位系数和子带相位系数，所述终端基于第一特征信息对多个第一信道信息进行分组包括：所述终端基于所述宽带相位系数对多个第一信道信息进行分组，得到一个或多个第二分组；所述终端基于所述子带相位系数对第二分组内的第一信道信息继续进行分组。即，终端先根据宽带相位系数进行分组，然后根据子带相位系数进行分组。
4)类型1(Type I)码本的第一预编码矩阵(W1)。
在一个例子中，所述第一特征信息包括所述W1；其中，所述终端基于第一特征信息对多个第一信道信息进行分组包括：所述终端基于所述W1的全部或部分比特对多个第一信道信息进行分组。
例如，W1的比特值可以分成多段，如W1分为3段，W1_1，W1_2，W1_3，可以先根据W1_1进行分组，然后根据W1_2进行分组，等等。
5)Type I码本的第二预编码矩阵(W2)。
在一个例子中，所述第一特征信息包括所述W2；其中，所述终端基于第一特征信息对多个第一信道信息进行分组包括：所述终端基于所述W2的全部或部分比特对多个第一信道信息进行分组。

6)子带数目。
在一个例子中，所述第一特征信息包括所述子带数目；其中，所述终端基于第一特征信息对多个第一信道信息进行分组包括：所述终端将包含的子带数目相同的第一信道信息分为一个分组。
可选地，终端在基于第一特征信息对多个第一信道信息进行分组包括：终端结合上述1)至6)中的多个第一特征信息对多个第一信道信息进行分组，例如，第一级根据波束信息进行分组，在具有的波束信息相同的分组内，根据幅度系数再进行分组。在具有的波束信息相同以及幅度信息相同的分组内，第一信道信息只需要携带相位信息即可。
以下将分两个实施例，对本申请实施例中的第一信道信息进行介绍。
