本公开实施例涉及通信技术领域,尤其涉及信道接入方法、配置方法、终端及网络侧设备。
在第五代(5th-Generation,5G)移动通信系统中,采用非授权的频段进行信号的收发。发送端在采用非授权的频段发送信号之前,需要监听该频段是否空闲,如果该频段空闲,则发送端可以接入物理信道,并采用该频段进行信号的发送。其中,发送端监听非授权频段是否空闲的时间长度与物理信道的信道接入参数相关。
而在当前的5G移动通信系统中,同一物理信道采用的是固定的信道接入参数,因此,发送端在接入某物理信道之前,监听非授权频段是否空闲的时间长度也是固定的,导致信道接入的灵活度较低。

请参见图1,图1是本公开实施例可应用的一种网络系统的结构图,如图1所示,包括终端11和网络侧设备12,其中,终端11和网络侧设备12之间可以通过网络进行通信。
在本公开实施例中,终端11也可以称作用户终端(User Equipment,UE), 具体实现时,终端11可以是手机、平板电脑(Tablet Personal Computer)、膝上型电脑(Laptop Computer)、个人数字助理(Personal Digital Assistant,PDA)、移动上网装置(Mobile Internet Device,MID)、可穿戴式设备(Wearable Device)或车载设备等终端侧设备,需要说明的是,在本公开实施例中并不限定终端11的具体类型。

为了便于描述,以下对本公开实施例涉及的一些内容进行说明:
新空口-非授权(New RAT Un-licensed,NR-U)简介
在5G系统中,采用非授权的频段进行数据的收发,信号的发送端需要满足非授权频段的使用规则。对于非授权的频段,发送端在发送信号之前需要监听该频段是否被占用(或空闲),如果没有被占用(或空闲),则发送端可以进行信号的发送。
当前5G系统设计中,不同的信道接入参数,UE监听非授权频段是否空闲的时间长度不同。示例性的,对于信道接入优先级类别比较高的情况,UE监听非授权频段空闲的时长更短,即,用更短的监听时间去获取可用的频率使用权限。其中,信道接入参数可以包括信道接入优先级类别(Channel Access Priority Class)和/或的信道接入类型(Channel Access type),但不仅限于此。
当前的5G系统中,对于不同的物理信道,可以采用不同的信道接入参数。但对于同一物理信道,采用的是固定的信道接入参数,无法区分业务类型对物理信道的信道接入参数进行处理。也就是说,对于同一物理信道,触发该物理信道的不同业务类型,采用的监听时间长度相同。因此,针对同一物理信道,高优先级的业务的用于探测非授权频段是否空闲的监听时间长度,相比低优先级的业务的监听时间长度,并不存在优势,容易导致高优先级的业务触发的信号发送延迟或导致无法发送。
针对上述问题,本公开实施例提供一种信道接入方法,使得终端可以根据触发物理信道的业务信息,确定物理信道的信道接入参数,进而确定监听时间 长度,从而可以提高信道接入的灵活度,使得高优先级的业务触发的信号发送更容易抢到信道,实现更短的信号发送延时和更少的信号丢失。
以下对本公开实施例的信道接入方法进行说明。
参见图2,图2是本公开实施例提供的信道接入方法的流程图。本实施例的信道接入方法应用于终端。
如图2所示,本实施例的信道接入方法包括以下步骤:
步骤201、根据业务信息和信道接入参数的对应关系,确定第一业务信息对应的目标信道接入参数,所述第一业务信息为触发第一物理信道的业务信息。
具体实现时,UE可以预先获取业务信息和信道接入参数的对应关系。其中,获取的具体表现方式与对应关系的来源相关。在本实施例中,可选的,所述对应关系由网络侧设备配置,或由协议预定义。
具体地,若对应关系由网络侧设备配置,则UE可以接收网络侧设备配置的业务信息和信道接入参数的对应关系。这样,网络侧设备可以对业务信息和信道接入参数的对应关系进行调整,从而可以提高对应关系确定的灵活度。
若对应关系由协议预定义,则UE可以直接从协议中读取业务信息和信道接入参数的对应关系。这样,网络侧设备无需发送上述对应关系,从而可以节约信令开销。
在上述对应关系中,业务信息可以用于触发物理信道,即触发物理信道进行信号发送,也可以称为触发物理信道发送;信道接入参数可以用于物理信道发送时的非授权频段的空闲检测。其中,物理信道可以为物理上行控制信道(Physical Uplink Control Channel,PUCCH)或物理随机接入信道(Physical Random Access Channel,PRACH),但不仅限于此。
可选的,所述信道接入参数可以包括信道接入优先级类别和信道接入类型中的至少一项。
需要说明的是,在本实施例中,信道接入优先级类别和信道接入类型的优先级可以与监听时间长度成反比,即,信道接入优先级类别越高,该信道接入优先级类别对应的监听时间长度越短,UE可以用更短的监听时间去获取可用的频段使用权限;信道接入类型的优先级越高,该信道接入类型对应的监听时间长度越短,UE可以用更短的监听时间去获取可用的频段使用权限。
可选的,所述业务信息可以包括触发事件和逻辑信道信息中的至少一项。
其中,触发事件可以理解为信号发送的触发事件;逻辑信道信息可以理解为触发信号发送对应的逻辑信道信息。
具体实现时,信号发送可以表现为随机接入过程的Msg1(消息1)的发送,或者,调度请求(Scheduling Request,SR)的发送,但不仅限于此。对于不同的信号发送,其触发事件可以不同。
进一步地,在随机接入过程中,所述触发事件可以包括以下至少一项:
无线资源控制(Radio Resource Control,RRC)空闲态(Idle)或非激活态(Inactive)的初始接入;
RRC非激活态的状态转换(如,转化到RRC连接态);
RRC连接重建立流程;
切换;
主辅小区(Primary Secondary Cell,PSCell)添加或变更;
RRC连接态的下行或上行数据到达,且上行同步状态为失步;
辅小区(Secondary Cell,SCell)的上行定时;
系统信息请求;
波束失败恢复。
其中,所述触发事件可以表现为随机接入过程的Msg1的发送的触发事件。
对于SR的发送,其触发事件可以是UE没有SR资源或SR达到最大发送次数,但不仅限于此。
进一步地,所述逻辑信道信息可以包括以下至少一项:
逻辑信道标识(如,逻辑信道1);
逻辑信道组标识(如,逻辑信道组1);
逻辑信道的优先级(如,逻辑信道优先级1);
逻辑信道对应的小区标识(如,小区1);
逻辑信道对应的小区类型标识(如,主小区(Primary Cell,PCell)、PSCell或SCell);
逻辑信道对应的小区组(如,主小区组(Master Cell Group,MCG)或辅小区主(Secondary Cell Group,SCG));
逻辑信道对应的数据类型控制信令(如,RRC控制信令)或业务数据(如,专属业务信道(Dedicated Traffic Channel,DTCH)对应的数据);
逻辑信道对应的控制信令类型(如,通用控制信道(Common Control Channel,CCCH)控制信令或DCCH控制信令)。
其中,所述逻辑信道信息可以表现为触发随机接入过程的Msg1发送对应的逻辑信道信息,或触发SR发送对应的逻辑信道信息。
在实际应用中,多个业务信息可以触发同一物理信道,进一步地,在上述对应关系中,触发同一物理信道的不同业务信息对应的信道接入参数可以不同。也就是说,网络侧设备可以配置或协议可以约定特定物理信道可用的多个(大于或等于2个)信道接入参数和信道接入参数对应的业务信息。
这样,UE在确定触发第一物理信道的第一业务信息后,可以通过查找上述对应关系,确定第一业务信息对应的目标信道接入参数,进而可以根据所述目标信道接入参数,执行第一物理信道的接入,即可以将所述目标信道接入参数确定为该物理信道的信道接入参数,从而可以提高信道接入的灵活度。
示例性的,对于PRACH信道的发送,网络侧设备可以配置:对于波束失败恢复触发的PRACH发送,PRACH的信道接入参数可以表现为“信道接入优先级类别1”和“信道接入类型1”;对于逻辑信道1的上行数据到达触发的PRACH发送,PRACH的信道接入参数可以表现为“信道接入优先级类别2”和“信道接入类型2”;对于逻辑信道2的上行数据到达触发的PRACH发送,PRACH的信道接入参数可以表现为“信道接入优先级类别3”和“信道接入类型2”。
这样,当UE的逻辑信道1(且该逻辑信道的逻辑信道优先级为1)的上行数据到达的时候,由该逻辑信道1的上行数据到达会生成缓冲状态报告(Buffer Status Report,BSR)上报,由于UE没有SR资源或SR达到最大发送次数,则包含该逻辑信道1的数据的BSR会触发PRACH上报,则该PRACH的信道优先级类别为“信道接入优先级类别2”,且信道接入类型为“信道接入类型2”。
步骤102、根据所述目标信道接入参数,执行所述第一物理信道的接入。
具体实现时,将所述目标信道接入参数用于第一物理信道发送时的非授权 频段的空闲检测。
在本实施例中,第一业务信息对应的目标信道接入参数的包括的项数可能是1,也可能大于1。
在所述目标信道接入参数包括的项数是1的情况下,UE可以直接采用所述目标信道接入参数,执行所述第一物理信道的接入,并在接入成功后,通过第一物理信道进行信号的发送。
在所述目标信道接入参数包括的项数大于1的情况下,可选的,所述根据所述目标信道接入参数,执行所述第一物理信道的接入,包括:
采用所述目标信道接入参数包括的信道接入优先级类别中,优先级最高的信道接入优先级类别,执行所述第一物理信道的接入;或者,
采用所述目标信道接入参数包括的信道接入优先级类别中,优先级最低的信道接入优先级类别,执行所述第一物理信道的接入;或者,
采用所述目标信道接入参数包括的信道接入类型中,优先级最高的信道接入类型,执行所述第一物理信道的接入;或者,
采用所述目标信道接入参数包括的信道接入类型中,优先级最低的信道接入类型,执行所述第一物理信道的接入。
应理解的是,所述目标信道接入参数包括的项数大于1的场景可以包括:
场景一、第一业务信息包括两个或两个以上业务信息,且上述两个或两个以上业务信息中,至少存在两个业务信息所对应的信道接入参数不同。
场景二、第一业务信息仅包括一个业务信息,但该业务信息对应的信道接入参数包括信道接入优先级类别和信道接入类型。
对于采用所述目标信道接入参数包括的信道接入优先级类别中,优先级最高的信道接入优先级类别,执行所述第一物理信道的接入的方式,示例性的,触发PRACH上报的BSR中包含了逻辑信道优先级1的数据(其对应“信道接入优先级类别1”)和逻辑信道优先级2的数据(其对应“信道接入优先级类别2”),则采用“信道接入优先级类别1”用于该PRACH的发送。
这样,UE可以通过缩短监听时间,缩短接入第一物理信道的时间,进而可以缩短经第一物理信道发送的信号的发送延时和降低信号的丢失。
对于采用所述目标信道接入参数包括的信道接入优先级类别中,优先级最 低的信道接入优先级类别,执行所述第一物理信道的接入的方式,示例性的,触发PRACH上报的BSR中包含了逻辑信道优先级1的数据(其对应“信道接入优先级类别1”)和逻辑信道优先级2的数据(其对应“信道接入优先级类别2”),则采用“信道接入优先级类别2”用于该PRACH的发送。
需要说明的是,在本公开实施例中,不同UE采用相同的规则,执行物理信道的接入。因此,在本方式中,尽管UE接入第一物理信道的时间较长,但本实施例的UE可以为其他UE(该UE的目标信道接入参数中最低优先级的信道接入优先级类别,高于本实施例UE的目标信道接入参数包括的最低优先级的信道接入优先级类别)节省接入物理信道的时间,进而可以缩短其他UE的信号发送延时和降低其他UE的信号丢失。
对于采用所述目标信道接入参数包括的信道接入类型中,优先级最高的信道接入类型,执行所述第一物理信道的接入的方式,示例性的,触发PRACH上报的BSR中包含了逻辑信道优先级1的数据(其对应“信道接入类型1”)和逻辑信道优先级2的数据(其对应“信道接入类型2”),则采用“信道接入类型1”用于该PRACH的发送。
这样,UE可以通过缩短监听时间,缩短接入第一物理信道的时间,进而可以缩短经第一物理信道发送的信号的发送延时和降低信号的丢失。
对于采用所述目标信道接入参数包括的信道接入类型中,优先级最低的信道接入类型,执行所述第一物理信道的接入的方式,示例性的,触发PRACH上报的BSR中包含了逻辑信道优先级1的数据(其对应“信道接入类型1”)和逻辑信道优先级2的数据(其对应“信道接入类型2”),则采用“信道接入优先级类别2”用于该PRACH的发送。
需要说明的是,在本公开实施例中,不同UE采用相同的规则,执行物理信道的接入。因此,在本方式中,尽管UE接入第一物理信道的时间较长,但本实施例的UE可以为其他UE(该UE的目标信道接入参数中最低优先级的信道接入类型,高于本实施例UE的目标信道接入参数包括的最低优先级的信道接入类型)节省接入物理信道的时间,进而可以缩短其他UE的信号发送延时和降低其他UE的信号丢失。
在实际应用中,UE可以先决定选择采用目标随机接入参数中的信道接入 优先级类别执行第一物理信道的接入,还是采用目标随机接入参数中的信道接入类型执行第一物理信道的接入。再进一步决定选择采用目标随机接入参数中最高级别或最低级别的信道接入优先级类别(或信道接入类型)执行第一物理信道的接入。
需要说明的是,本公开实施例中介绍的多种可选的实施方式,彼此可以相互结合实现,也可以单独实现,对此本公开实施例不作限定。
本实施例的信道接入方法,终端根据业务信息和信道接入参数的对应关系,确定第一业务信息对应的目标信道接入参数,所述第一业务信息为触发第一物理信道的业务信息;根据所述目标信道接入参数,执行所述第一物理信道的接入。可见,本公开可以基于触发第一物理信道的业务信息,确定第一物理信道的信道接入参数,进而确定监听时间长度,从而可以提高信道接入的灵活度。
