Description

一种接收及发送上行信道配置信息的方法、装置及介质 技术领域
本公开涉及无线通信技术领域,尤其涉及一种接收及发送上行信道配置信息的方法、装置及存储介质。
背景技术
在无线通信系统中,例如5G新无线(new radio,NR)通信系统中,将下行数据承载在物理下行共享信道(physical downlink shared channel,PDSCH)上,将上行数据承载在物理上行共享信道(physical uplink shared channel,PUSCH)上。基站设备通过承载在物理下行控制信道(physical downlink control channel,PDCCH)的下行控制信息(downlink control information,DCI)调度PDSCH和PUSCH。
在NR 52.6-71GHz对应于非授权频谱的场景中,在非授权频谱上,发送端可遵循先听后说(listen before talk,LBT)的信道接入(channel access)机制。在LBT机制中,发送端需要对信道进行监听,以进行空闲信道检测(clear channel assessment,CCA)。在CCA之后发送端占用空闲的信道发送数据,信道非空闲时则不能占用。发送端占用信道的最大时长(maximum channel occupy time,MCOT)由协议约定或者基站配置/指示。
在一些场景中,发送端发送数据前可能不需进行LBT,而是进行免竞争传输(contention exemption transmission,CET)。如何确定上行信道是否可以进行CET是需要解决的问题。

工业实用性
网络设备可以根据上行信道特点确定其能否使用免竞争传输,从而合理的配置对应的传输方式指示信息,并将传输方式指示信息发送至用户设备。用户设备根据接收的传输方 式指示信息,确定自身是否可以进行免竞争传输。当用户设备可以进行免竞争传输时,用户设备可以不进行先听后说的信道接入方式,而直接占用信道进行发送数据,从而能够更及时的发出消息,提升通信效率。进而使用免竞争传输的用户设备101更有利于传输高优先级的信息,如超高可靠低时延通信业务的信息。
