Description

一种确定信道接入方式的方法、装置及可读存储介质 技术领域
本公开涉及无线通信技术领域,尤其涉及一种确定信道接入方式的方法、装置及可读存储介质。
背景技术
在无线通信技术中,例如在第五代移动通信技术(5th Generation Mobile Communication Technology,简称5G)中,在非授权频谱上,发送端在占用信道发送数据之前,一般都需要对信道进行监听,即进行空闲信道评估(clear channel assessment,CCA)。发送端执行空闲信道评估后,如果确定信道空闲,则可以占用信道收发数据,其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;如果确定信道已被占用,则不能占用信道。此过程一般被称为非授权频段上的先听后说(LBT,listen before talk)的信道接入(channel access)机制。LBT还可以根据具体的信道接入参数分成不同的类型。
在非授权频谱上,还可以使用免LBT的信道接入方式,即发送端不需要做信道监听,就可以直接占用信道。

鉴于第二类型信道接入方式(Type 2 channel access)一般用在UE共享gNB的COT的场景中,要求gNB最近的下行传输的结束时间与UE传输的起始时间之间的间隔小于一定的gap Y。如果gNB采用share COT的方式,使用1个DCI调度多个PUSCH,且第一个PUSCH的传输起始时间与基站的下行传输的结束时间之间的间隔小于gap Y,那么第一个传输突发可以按照gNB的指示应用第二类型信道接入方式(Type 2 channel access)。但是对于后续各个传输突发,基站如果想保证最近的下行传输的结束时间与UE开始传输此传输突发的时间之间的间隔小于gap Y,就会比较困难,所以确定对第2个及之后的传输突发使用第一类型信道接入方式(Type 1 channel access)。
