Description

一种子帧调度方法及基站 技术领域
本发明涉及通信技术领域,具体涉及一种子帧调度方法及基站。
背景技术
无线通信系统使用的频谱包括授权频谱(licensed spectrum)和非授权频谱(unlicensed spectrum),授权频谱是只能被授权用户使用的频谱,非授权频谱是可以被任何用户使用的频谱。授权频谱上的载波称为授权载波,非授权频谱上的载波称为非授权载波。因此,当基站需要使用非授权频谱时,需要通过先听后发(Listen Before Talk,LBT)方式抢占信道。目前,在长期演进的授权辅助接入(Licensed-Assisted Access Using Long Term Evolution,LAA-LTE)系统中,基站抢占到信道之后,会将发送数据的起始符号的编号发送给终端,以便终端可以通过该编号接收并解调相应的数据。而由于在3GPP RAN1 5G的帧结构研究中,增加了微时隙(mini-slot)类型,因此若在5G的非授权载波上发送数据时,只将发送数据的起始符号的编号发送给终端,此时终端并不知道该子帧中可能包含的帧结构类型,从而增加了终端侧的接收复杂度。
发明内容
本发明实施例公开了一种子帧调度方法及基站,用于简化终端的处理过程。
第一方面公开了一种子帧调度方法,该方法应用于基站,当基站抢占到非授权载波时,获取抢占到的非授权载波的起始位置,根据抢占到的非授权载波的起始位置确定第一编号和第一子帧的类型,并将第一子帧的类型和第一编号发送给终端。第一编号为基站用于发送数据的第一子帧中的起始位置对应的符号编号,第一子帧为第一编号对应的符号所在的子帧,由于将第一子帧的类型发送给了终端,因此,终端可以根据第一子帧的类型确定其相应的接收解调方式,从而可以简化终端的处理过程。
在一个实施例中,微时隙可以包括的符号数量大于0且小于7,当微时隙 包括的符号数量是可变的时,当该起始位置为符号边界,且该起始位置对应的符号编号为0时,确定第一子帧的类型为子帧,并将0确定为第一编号;当该起始位置为符号边界,且该起始位置对应的符号编号大于0且小于7时,确定第一子帧的类型为微时隙与时隙,并将起始位置对应的符号编号确定为第一编号;当该起始位置不是符号边界,且该起始位置对应的符号编号大于或等于0且小于6时,确定第一子帧的类型为微时隙与时隙,并将与该起始位置对应的符号编号相邻的下一个编号确定为第一编号;当该起始位置不是符号边界,且该起始位置对应的符号编号为6时,确定第一子帧的类型为时隙,并将7确定为第一编号。其中,第一子帧的类型可以包括子帧、微时隙与时隙、时隙和微时隙,子帧即表明第一子帧从符号0开始发送数据,微时隙与时隙即表明第一子帧从符号1-6中的任一符号开始发送数据,时隙即表明第一子帧从符号7开始发送数据,微时隙即表明第一子帧从符号8-13中的任一符号开始发送数据。因此,在微时隙包括的符号数量是可变的情况下,当该起始位置为符号边界且该起始位置对应的符号编号大于0且小于7,或者该起始位置不是符号边界且该起始位置对应的符号编号大于或等于0且小于6时,可以使用第一子帧中符号7之前的符号发送数据,而不必等待到符号7才开始发送数据,因此,可以增加用于发送数据的符号的数量,从而在简化终端的处理过程同时,可以提高信道利用率。

具体实施方式
本发明实施例公开了一种子帧调度方法及基站,用于简化终端的处理过程。
为了更好地理解本发明实施例公开的一种子帧调度方法及基站,下面先对本发明实施例使用的基站概念进行描述。目前,在传统的LTE 4G网络中,基站发送数据是以子帧为基本单位的,一个子帧包括14个符号,一个子帧包括2个时隙(slot),每个时隙包括7个符号,一个子帧内的符号编号从0开始到13结束。请参阅图1,图1是本发明实施例公开的一种子帧的示意图。如图1所示, 符号1-6为第一个时隙,符号7-13为第二个时隙。目前,在LAA-LTE系统中,基站抢占到信道之后,只能在符号0或者符号7处开始发送数据,因此,当抢占到信道不在符号0或符号7时,需要发送保留信号(reservation signal)到时隙边界或子帧边界。其中,保留信号用于占着信道,不被其他网络节点抢占信道,但保留信号内不发送任何数据。由于当抢占到信道不在符号0或符号7时,需要发送保留信号到时隙边界或子帧边界,而保留信号不发送任何数据,以致降低了信道利用率。此外,本发明实施例提出了一种新的概念,即微时隙(mini-slot),微时隙包括的符号的数量小于时隙,包括的符号的数量大于0且小于7。
为了更好地理解本发明实施例公开的一种子帧调度方法及基站,下面先对本发明实施例使用的网络架构进行描述。请参阅图2,图2是本发明实施例公开的一种网络架构示意图。如图2所示,该网络架构可以包括基站201和终端202,基站201与终端202可以通过网络连接。当基站201需要与终端202通过非授权载波进行通信时,基站201,用于抢占非授权载波,根据抢占到的非授权载波的起始位置确定用于发送数据的起始位置对应的符号编号和用于发送数据的第一子帧的类型,将确定的符号编号和第一子帧的类型通过授权载波或非授权载波发送给终端202,以及将待发送数据通过抢占到的非授权载波发送给终端202。终端202,用于接收基站201发送的符号编号、第一子帧的类型以及待传输数据,并根据第一子帧的类型确定用于解码第一子帧的解码方式,之后根据该解码方式和符号编号对待传输数据进行解码。其中,第一子帧的类型可以包括子帧、微时隙与时隙、时隙以及微时隙,子帧即表明第一子帧从符号0开始发送数据,微时隙与时隙即表明第一子帧从符号1-6中的任一符号开始发送数据,时隙即表明第一子帧从符号7开始发送数据,微时隙即表明第一子帧从符号8-13中的任一符号开始发送数据。其中,子帧和时隙的定义可以与传统定义相同,也可以与传统定义不同。其中,基站101可以是接入网中在空中接口上通过一个或多个扇区与终端进行通信的设备,如长期演进(Long Term Evolution,LTE)或长期演进升级版(LTE-Advanced,LTE-A)等系统中的演进型基站(evolutional Node B,NodeB或eNB或e-NodeB)、5G 新无线(New Radio,NR)技术中的gNB或g-NodeB等,可用于将接收到的空中帧与网际协议(Internet Protocol,IP)分组进行相互转换,作为终端与接入网的其余部分之间的路由器,接入网的其余部分可包括IP网络;还可用于协调空中接口的属性管理。
