背景技术
在当前5G(5th Generation,第五代)NR(New RAT,新空口)移动通信通信系统中,小区的覆盖范围是重要的技术指标。而Msg3 PUSCH(Physical Uplink Shared Channel,物理上行共享信道)传输是5G NR系统中覆盖的瓶颈。因此如何增强Msg3 PUSCH的覆盖范围是当前研究的重要课题。
目前针对Msg3 PUSCH传输引入repetition type A的重传机制。但是,如何确定Msg3 PUSCH重复传输次数,当前并没有明确的方案。同时,考虑到Msg3 PUSCH的传输处于初始接入阶段,此时的终端仅能获得SIB(System Information Block,系统信息块)1发送的小区公共的TDD上下行配置,无法获知其他终端的终端专用UE-dedicated上下行配置。当Msg3 PUSCH在多个slot上进行发送时,如何确定可用的上行时隙,当前并没有明确的方法。

本申请实施例中术语“多个”是指两个或两个以上,其它量词与之类似。
下面将结合本申请实施例中的附图,对本申请实施例中的技术方案进行清楚、完整地描述,显然,所描述的实施例仅仅是本申请一部分实施例,并 不是全部的实施例。基于本申请中的实施例,本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例,都属于本申请保护的范围。
本申请实施例提供了一种重复传输的确定方法及装置。其中,方法和装置是基于同一申请构思的,由于方法和装置解决问题的原理相似,因此装置和方法的实施可以相互参见,重复之处不再赘述。
如图1所示,为本公开实施例提供的重复传输的确定方法的流程示意图,应用于终端,该方法包括:
步骤101:终端获取随机接入响应RAR,其中,RAR包括上行授权UL grant和除UL grant之外的第一信息;
步骤102:终端根据所述UL grant和/或所述第一信息,确定Msg3初始传输的重复传输次数;
这里,终端可以根据UL grant或者第一信息,或者UL grant以及第一信息,确定Msg3初始传输的重复传输次数,这样,能够提高Msg3资源分配的灵活性。
步骤103:终端根据Msg3初始传输的重复传输次数以及传输所述Msg3的可用时隙,确定用于传输所述Msg3的目标时隙。
本步骤中,终端基于Msg3初始传输的重复传输次数以及传输所述Msg3的可用时隙,能够确定出用于传输所述Msg3的目标时隙,从而确保终端在后续发送Msg3时能够正确确定可以使用的上行时隙。
本公开实施例的重复传输的确定方法,终端通过获取随机接入响应RAR,其中,RAR包括上行授权UL grant和除UL grant之外的第一信息;根据所述UL grant和/或所述第一信息,确定Msg3初始传输的重复传输次数;并根据Msg3初始传输的重复传输次数以及传输所述Msg3的可用时隙,确定用于传输所述Msg3的目标时隙,如此,能够基于UL grant和/或RAR中除该UL grant之外的第一信息,确定Msg3初始传输的重复传输次数,进而确定用于传输所述Msg3的可用的上行时隙,能够提高Msg3资源分配的灵活性,同时保证其传输性能。
作为一可选的实现方式,本公开实施例的方法还可包括:
接收网络侧设备发送的第一指示信令,所述第一指示信令用于指示下述 任意一项:
用于指示终端根据所述第一信息,确定Msg3初始传输的重复传输次数;
用于指示终端根据所述UL grant,确定Msg3初始传输的重复传输次数;
用于指示终端根据所述第一信息和所述UL grant,确定Msg3初始传输的重复传输次数。
也就是说,通过网络侧设备发送的第一指示信令,指示终端是根据第一信息、还是根据UL grant、还是根据第一信息以及UL grant,确定Msg3初始传输的重复传输次数。
可选地,第一指示信令为SIB1携带的指示信令。具体的,第一指示信令由SIB1携带的N bits信息进行指示,N为大于或者等于1的整数。
需要说明的是,对于第一信息以及UL grant内的相关信息域的定义不做任何限定。
假设系统中存在需要进行覆盖增强的终端。为了保证其随机接入过程的可靠性,需要对Msg3进行重复传输。Msg3 PUSCH的传输可分为重复传输次数的指示以及时域资源的确定两个步骤。
在一示例中,网络侧设备(如基站)通过SIB1携带的指示信令,指示终端根据第一信息携带的信息确定Msg3初始传输的重复传输次数或者根据UL grant携带的信息确定Msg3初始传输的重复传输次数。
具体的,所述SIB1携带的指示信令包括1bit指示信息,指示确定Msg3初始传输的重复传输次数的方法。在该示例中,所述1bit指示信息具有如下功能:
Figure PCTCN2022088441-appb-000001
如果SIB1中携带的指示信息为状态0,则网络侧设备通过第一信息携带 的信息指示Msg3 PUSCH初始传输的重复次数;如果SIB1中携带的指示信息为状态1,则网络侧设备通过UL grant中携带的信息指示Msg3 PUSCH初始传输的重复次数。本示例对于第一信息以及UL grant内的相关信息域的定义不做任何限定。
需要说明的是,由于终端处于初始随机接入阶段,因此,此时只能获得由SIB1发送的小区级别的时分双工上下行配置TDD UL-DL configuration。但是对于其他已进入连接态的终端而言,网络侧设备可以为其配置终端专用UE-dedicated的TDD UL-DL configuration,UE-dedicated的TDD配置可以将半静态灵活符号semi-static flexible symbol配置成DL。这里,
当然,网络侧设备(如基站)还可通过SIB1携带的指示信令,指示终端根据第一信息携带的信息以及UL grant携带的信息,共同确定Msg3初始传输的重复传输次数。
作为一可选的实现方式,本公开实施例的方法步骤102,终端根据所述UL grant和所述第一信息,确定Msg3初始传输的重复传输次数,包括:
根据所述第一信息中的预留比特位以及所述UL grant中的预留比特位,确定Msg3初始传输的重复传输次数。
这里,根据第一信息中的预留比特位reserved bits以及UL grant中的预留比特位reserved bits共同确定Msg3初始传输的重复传输次数。
作为另一可选的实现方式,本公开实施例的方法步骤102,终端根据所述UL grant和所述第一信息,确定Msg3初始传输的重复传输次数,包括:
根据所述第一信息中携带的定时提前TA值的取值范围以及所述UL grant中携带的指示信息,确定Msg3初始传输的重复传输次数。
这里,根据第一信息中携带的定时提前TA值的取值范围,即TA range,以及UL grant中携带的指示信息共同确定Msg3初始传输的重复传输次数。
具体的,根据所述第一信息中携带的定时提前TA值的取值范围以及所述UL grant中携带的指示信息,确定Msg3初始传输的重复传输次数,包括下述方法中的至少一者:
通过所述第一信息中携带的TA值的取值范围,确定所使用的时域资源分配表;通过所述UL grant中携带的TDRA指示域指示所述时域资源分配表 中的时域资源分配信息;并根据所述时域资源分配信息,确定Msg3初始传输的重复传输次数;
这里,基站在第一信息中携带的TA command信息域,指示对应的TA值,终端接收第一信息中携带的TA command,并确定对应的TA值。基站和终端通过预定义的规则,确定TA值的取值区间与时域资源分配表TDRA table的关系。例如,当TA值小于或者等于第一门限值(该第一门限值通过预定义方式或网络侧配置方式(比如SIB1)确定)时,采用TDRA table#1;当TA值大于第一门限值时,采用TDRA table#2。进一步地,终端和基站基于对应的TDRA table进行Msg3初始传输的重复传输次数。
通过所述第一信息中携带的TA值的取值范围,确定Msg3初始传输的重复传输次数的取值范围;并通过所述UL grant中携带的第一指示信息,在所述重复传输次数的取值范围内指示Msg3初始传输的重复传输次数;
这里,基站在第一信息中携带的TA command信息域,指示对应的TA值,终端接收第一信息中携带的TA command,并确定对应的TA值。基站和终端通过预定义或者SIB1通知的规则,确定TA值的取值区间与Msg3 PUSCH repetition number取值区间(即Msg3初始传输的重复传输次数的取值范围)的关系。例如,当TA值小于或者等于第二门限值(该第二门限值通过预定义方式或网络侧配置方式(比如SIB1)确定)时,Msg3 PUSCH repetition number取值区间为{a1,a2,a3…};当TA值大于第二门限值时,Msg3 PUSCH repetition number取值区间为{b1,b2,b3…}。进一步地,基站和终端基于对应的Msg3 PUSCH repetition number取值区间,根据UL grant中携带的重复传输次数指示域确定实际采用的重复传输次数。
通过所述第一信息中携带的TA值的取值范围,确定Msg3初始传输的重复传输次数的缩放因子;并通过所述UL grant中携带的第二指示信息,确定所述UL grant指示的重复传输次数;根据所述缩放因子和所述UL grant指示的重复传输次数,确定Msg3初始传输的重复传输次数。
这里,基站在第一信息中携带的TA command信息域,指示对应的TA值,终端接收第一信息中携带的TA command,并确定对应的TA值。基站和终端通过预定义或者SIB1通知的规则,确定TA值的取值区间与Msg3初始传输 的重复传输次数Msg3 PUSCH repetition number的缩放因子的关系。例如,当TA值小于第三门限值T时,缩放因子(scaling factor)K=1;当TA值大于或者等于T时,缩放因子K=2。进一步地,通过UL grant中携带的相关指示信息所指示的重复传输次数R以及缩放因子K,确定Msg3初始传输的重复传输次数为K*R。
作为一可选的实现方式,本公开实施例的方法还可包括:
根据预定义的规则或网络指示,确定用于传输所述Msg3的可用时隙。
一可选地,本步骤中,根据预定义的规则,确定用于传输所述Msg3的可用时隙,包括下述方法中的一者:
将且仅将半静态上行时隙,作为用于传输所述Msg3的可用时隙;
将半静态上行时隙以及半静态灵活时隙,作为用于传输所述Msg3的可用时隙;
其中,所述半静态灵活时隙不包括用于传输下述至少一种信道或者信息的半静态灵活符号:
同步信号块SSB;
控制资源集CORSET#0;
类型0的公共搜索空间CSS。
这里,终端通过本公开实施例方法步骤102获取了Msg3初始传输的重复传输次数之后,可通过上述方法中的一者确定用于传输所述Msg3的可用时隙。
需要说明的是,在半静态上行时隙以及半静态灵活时隙,作为用于传输所述Msg3的可用时隙的情况下,在传输了所述Msg3的所有符号上,基站不在上述传输了所述Msg3的所有符号发送任何UE-dedicated的下行数据或者信号;而且终端也不期待基站发送任何UE-dedicated的下行数据或者信号,如此能够避免需要重复传输Msg3的终端中有些重复与其他终端的下行冲突而导致传输失败,避免Msg3 PUSCH的传输性能受损。
一者,对于终端在获取了Msg3初始传输的重复传输次数之后,将且仅将半静态上行时隙,作为用于传输所述Msg3的可用时隙,下面就一具体示例进行说明。
如图2所示,假设SIB1通知的TDD UL-DL configuration结构为DDSUUDDSUU。额外地,SIB1通过Msg3 PUSCH repetition指示方式信息域指示通过第一信息或者UL grant指示Msg3初始传输的重复传输次数。在本示例中,假设基站通过UL grant中的相关信息指示Msg3初始传输的重复传输次数,并假设其重复传输次数为4,则由于用于传输所述Msg3的可用时隙仅为半静态上行时隙,所以,基于重复传输次数以及半静态上行时隙(图中用斜线表示的框图部分),确定用于传输Msg3的目标时隙,即为图中的4个用斜线表示的框图部分所表示的时隙,即半静态上行时隙。
另一者,对于终端在获取了Msg3初始传输的重复传输次数之后,将半静态上行时隙以及半静态灵活时隙,作为用于传输所述Msg3的可用时隙,下面就一具体示例进行说明。
如图3所示,假设SIB1通知的TDD UL-DL configuration结构为DDDDSSSSUU。额外地,SIB1通过Msg3 PUSCH repetition指示方式信息域指示通过第一信息或者UL grant指示Msg3初始传输的重复传输次数。在本示例中,假设基站通过UL grant中的相关信息指示Msg3初始传输的重复传输次数,并假设其重复传输次数为4。假设终端在第四个DL slot上检测接收到UL grant,且UL grant内携带的时域资源指示域指示K2=1,也即Msg3在UL grant传输的slot之后的第一个slot传输。假设网络侧在slot#5上发送了Type0-CSS。则可用于发送Msg3 PUSCH的slot如图3中的4个用横线表示的框图部分所表示的时隙。
在该示例中,Msg3 PUSCH的传输只能在semi-static UL以及没有用于传输SSB/CORESET#0/Typ0CSS的semi-static flexible symbols上发送。当终端遇到不能发送Msg3 PUSCH的symbol或者slot时,将该Msg3 PUSCH的重复传输向后延迟。
对于没有发送SSB/CORESET#0/Typ0CSS的semi-static flexible symbols,终端不期待基站在这些符号上调度任何下行传输。基站在为终端配置UE-dedicated TDD UL DL configuration时,不会把这些符号设置成DL,也不会调度其他终端的下行传输。如此,能够避免需要重复传输Msg3的终端中有些重复与其他终端的下行冲突而导致传输失败,避免Msg3 PUSCH的传输 性能受损。
另一可选地,本步骤中,根据网络指示,确定用于传输所述Msg3的可用时隙,包括:
接收网络侧设备发送的第二指示信令,所述第二指示信令用于指示终端按照下述方法中的一者确定用于传输所述Msg3的可用时隙:
将且仅将半静态上行时隙,作为用于传输所述Msg3的可用时隙;
将半静态上行时隙以及半静态灵活时隙,作为用于传输所述Msg3的可用时隙;
其中,所述半静态灵活时隙不包括用于传输下述至少一种信道或者信息的半静态灵活符号:
SSB;
CORSET#0;
类型0的CSS。
可选地,若用于传输所述Msg3的可用时隙包括所述半静态灵活时隙,则终端不期待网络侧设备在所述Msg3所占用的半静态灵活符号上传输下行数据或者配置下行符号。
可选地,终端可通过网络侧设备发送的SIB1携带的相关信息(即第二指示信令)的指示,确定相应的确定用于传输所述Msg3的可用时隙的方法。
作为一可选的实现方式,在确定用于传输所述Msg3的目标时隙之后,本公开实施例的方法还可包括:
在确定的目标时隙上,发送Msg3。
本公开实施例的重复传输的确定方法,终端通过获取随机接入响应RAR,其中,RAR包括上行授权UL grant和除UL grant之外的第一信息;根据所述UL grant和/或所述第一信息,确定Msg3初始传输的重复传输次数;并根据Msg3初始传输的重复传输次数以及传输所述Msg3的可用时隙,确定用于传输所述Msg3的目标时隙,如此,能够基于UL grant和/或RAR中除该UL grant之外的第一信息,确定Msg3初始传输的重复传输次数,进而确定用于传输所述Msg3的可用的上行时隙,能够提高Msg3资源分配的灵活性,同时保证其传输性能。
如图4所示,为本公开实施例提供的重复传输的确定方法的流程示意图,应用于网络侧设备,包括:
步骤401:网络侧设备通过随机接入响应RAR中的上行授权UL grant和/或除UL grant之外的第一信息,指示终端Msg3初始传输的重复传输次数;
这里,网络侧设备可以通过UL grant或者第一信息,或者UL grant以及第一信息,指示终端Msg3初始传输的重复传输次数,这样,能够提高Msg3资源分配的灵活性。
步骤402:网络侧设备根据所述Msg3初始传输的重复传输次数以及传输所述Msg3的可用时隙,确定用于传输所述Msg3的目标时隙。
本步骤中,网络侧设备基于Msg3初始传输的重复传输次数以及传输所述Msg3的可用时隙,能够确定出用于传输所述Msg3的目标时隙,从而确保网络侧设备能够在正确的上行时隙上接收Msg3。
本公开实施例的重复传输的确定方法,网络侧设备通过随机接入响应RAR中的上行授权UL grant和/或除UL grant之外的第一信息,指示终端Msg3初始传输的重复传输次数;并根据所述Msg3初始传输的重复传输次数以及传输所述Msg3的可用时隙,确定用于传输所述Msg3的目标时隙,如此,能够基于UL grant和/或RAR中除该UL grant之外的第一信息,确定Msg3初始传输的重复传输次数,进而确定用于传输所述Msg3的可用的上行时隙,从而提高Msg3资源分配的灵活性,同时保证其传输性能。
