Description

信息识别方法、装置、及通信设备
交叉引用
本发明要求在2021年04月28日提交中国专利局、申请号为202110469406.4、发明名称为“信息识别方法、装置、及通信设备”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
本申请属于移动通信技术领域,具体涉及一种信息识别方法、装置、及通信设备。
背景技术
对于副链接(sidelink)传输场景,sidelink的资源选择技术可以选择增强的方式,例如,如图1所示,考虑由数据接收端的用户设备11(RXUE)向数据发送端的用户设备12(TXUE)提供推荐资源,TX UE12利用所述推荐资源进行数据传输;或者RX UE11向TX UE12推荐不利于传输的资源,TX UE12在资源选择时排除掉这些资源;或者,如图2所示,由资源进行传输负责协调的UE13(Co-UE)向另一个UE(例如TX UE12)推荐资源,TX UE利用所述推荐资源进行传输或者在资源选择时排除掉该资源。
以新空口(New Radio,NR)sidelink技术中副链路控制信息(Sidelink Control Information,SCI)为例,SCI是与数据一起发送的,并且在SCI中携带的资源信息包含了当前SCI关联的数据所占用的资源。所以当推荐信息或者调度信息或者辅助信息的资源信息在SCI中携带时。由于SCI是与数据一起发送的,所以对于辅助信息或者调度信息的接收端来说,该SCI关联的数据信息是无用的,会增加接收端的解码负担,增大功耗。
