Description

通信处理方法以及通信装置
本申请要求于2021年8月26日提交中国专利局,申请号为202110990898.1,发明名称为“通信处理方法以及通信装置”的中国专利申请的优先权,其全部内容通过引用结合在本申请中。
技术领域
本申请涉及通信技术领域,尤其涉及一种通信处理方法以及通信装置。
背景技术
随着室内定位的发展,各种各样的定位终端在工业工厂、室内商场、物流中心等得到广泛应用。在室内定位中,定位终端的续航时间大多较短,由此低功耗定位成为当前研究的热点话题,以降低定位终端的功耗开销,提升定位终端设备的续航时间。
目前,采用非连续收发(discontinuous reception and transmission,DRX)模式实现低功耗定位。在DRX周期内,终端设备根据探测参考信号(sounding reference signal,SRS)的配置信息定期的从深度睡眠(deep sleep)模式醒来进入微睡眠(micro sleep)模式。终端设备先通过跟踪参考信号(tracking reference signals,TRS)实现下行时频跟踪。然后,终端设备在发送SRS的时刻向接入网设备发送SRS,接入网设备测量SRS以确定终端设备的位置,从而实现对终端设备的定位。而当该终端设备移动重选至邻居小区之后,终端设备需要从空闲态或未激活态且切换至连接态,以获取邻居小区的服务基站为该终端设备配置的TRS配置信息。
由此可知,终端设备进入邻居小区都需要从空闲态或未激活态且切换至连接态,以获取邻居小区的服务基站为该终端设备配置的TRS配置信息,导致终端设备的功耗开销较大。
发明内容

上述技术方案中,终端设备在重选至第二小区之前,终端设备先接收来自网络设备的第二小区的TRS配置信息,便于终端设备从第一小区重选至第二小区之后,终端设备可以直接基于第二小区的TRS配置信息接收第二小区的TRS。终端设备无需从空闲态或未激活态切换至连接态,以获取邻居小区的服务基站为该终端设备配置的TRS配置信息。避免终端设备重选至第二小区之后切换至连接态带来的功耗开销。从而降低终端设备的功耗开销,提升终端设备的续航时间。

S201、网络设备获取至少一个小区的TRS配置信息。
终端设备处于第一小区,该至少一个小区是第一小区的邻居小区。该至少一个小区的TRS配置信息可以理解是为该终端设备配置的该至少一个小区的TRS配置信息。
在一些实施例方式中,该至少一个小区和第一小区是该终端设备所在的定位区域内的小区,该至少一个小区可以包括该定位区域内除第一小区外的其他部分或全部小区。也就是说该定位区域内除第一小区外的其他小区都可以称为该第一小区的邻居小区。
例如,如图4所示,该终端设备所在的用户专属定位区域(user-centric positioning area,UCPA)中,终端设备在时刻1接入gNB1的小区。至少一个小区可以包括该UCPA区域中除gNB1之外其他gNB的小区的TRS配置信息。例如,该至少一个小区可以包括gNB2的小区、gNB3的小区、gNB4的小区等。
在一些实施方式中,该至少一个小区的TRS配置信息包括该至少一个小区的标识和该至少一个小区分别为该终端设备配置的TRS资源。
该至少一个小区的标识用于标识TRS配置信息是哪个小区的TRS配置信息。该至少一个小区的TRS资源用于终端设备接收该至少一个小区的TRS。该至少一个小区的TRS用于终端设备与该至少一个小区进行时频跟踪,以实现与该至少一个小区的时频同步。例如,该至少一个小区的TRS为信道状态信息参考信号(channel state information reference signal,CSI-RS),该CSI-RS用于终端设备进行时频跟踪。
例如,该至少一个小区的TRS配置信息包括gNB2的小区的TRS配置信息。TRS资源用于终端设备接收来自该gNB2的TRS,并通过gNB2的TRS进行时频跟踪,以实现与该gNB2的小区时频同步。
需要说明的是,上述TRS仅仅是一种示例,本申请中对TRS的名称不做限定。
可选的,网络设备可以为定位设备或者为第一接入网设备。第一接入网设备为终端设 备的服务基站。定位设备可以为LMF。
对于网络设备为定位设备的实现方式,具体请参阅后文图3所示的实施例介绍定位设备获取该至少一个小区的TRS配置信息的过程;对于网络设备为第一接入网设备的实现方式,具体请参阅后文图6所示的实施例介绍第一接入网设备获取该至少一个小区的TRS配置信息的过程,这里不再赘述。
S202、网络设备向终端设备发送至少一个小区的TRS配置信息。相应的,终端设备接收来自网络设备的至少一个小区的TRS配置信息。
在一些实施方式中,网络设备为定位设备,定位设备向终端设备发送提供辅助信息(provide assistant data)消息,该提供辅助信息消息包括该至少一个小区的TRS配置信息。
具体的,定位设备可以通过长期演进定位协议(long term evolution positioning protocol,LPP)信令以提供辅助信息消息的形式向终端设备发送该至少一个小区的TRS配置信息。
例如,如图4所示,网络设备为LMF,终端设备接入gNB1的小区。LMF向终端设备发送提供辅助信息消息,该提供辅助信息消息包括:gNB2的小区的TRS配置信息、gNB3的小区的TRS配置信息、gNB4的小区的TRS配置信息。
在一些实施方式中,网络设备为第一接入网设备,第一接入网设备向终端设备发送RRC消息,该RRC消息包括该至少一个小区的TRS配置信息。
例如,如图7所示,终端设备接入gNB1的小区,网络设备为gNB1。gNB1向终端设备发送RRC消息,RRC消息包括:gNB4的小区的TRS配置信息、gNB5的小区的TRS配置信息、gNB6的小区的TRS配置信息。
S203、当终端设备从第一小区重选至第二小区,且至少一个小区的TRS配置信息包括第二小区的TRS配置信息,终端设备基于第二小区的TRS配置信息接收TRS。
具体的,第二小区为第二接入网设备的小区,终端设备从第一小区重选到第二小区,终端设备可以通过第二小区的标识确定该至少一个小区的TRS配置信息中是否包括该第二小区的TRS配置信息。如果该至少一个小区的TRS配置信息包括第二小区的TRS配置信息,终端设备可以基于第二小区的TRS配置信息接收来自第二接入网设备的TRS。
需要说明的是,如果终端设备没有重选到该第二小区,且至少一个小区的TRS配置信息包括该第二小区的TRS配置信息,第二接入网设备在该第二小区的TRS配置信息所配置的TRS资源上仍会发送该第二小区的TRS。
例如,如图4所示,终端设备在时刻1接入gNB1的小区,终端设备在时刻2重选到gNB2的小区。若终端设备在上述S202中获取到该gNB2的小区的TRS配置信息,终端设备可以基于该gNB2的小区的TRS配置信息接收来自该gNB2的TRS2。
可选的,图2所示的实施例还包括步骤S204和S205。步骤S204和步骤S205可以在步骤S203之后执行。
S204、终端设备基于第二小区的TRS进行时频跟踪。
例如,终端设备在时刻1接入gNB1的小区,终端设备在时刻2重选到gNB2的小区。 终端设备可以基于该gNB2的小区的TRS配置信息接收来自该gNB2的TRS2,终端设备基于TRS2进行时频跟踪,以实现与该gNB2的小区的时频同步。
S205、终端设备发送SRS。SRS用于对终端设备进行定位。
具体的,第二小区为第二接入网设备的小区,终端设备通过第二小区的TRS进行时频跟踪实现与第二小区时频同步之后,终端设备向第二接入网设备发送SRS,第二接入网设备测量SRS,以确定终端设备的位置。例如,如图5所示,第二小区为gNB2的小区,终端设备从深度睡眠(deep sleep)模式切换到微睡眠(micro sleep)模式后,终端设备基于gNB2的小区的TRS配置信息接收来自gNB2的TRS2,并通过TRS2进行时频跟踪以实现与gNB2的小区时频同步。终端设备处于微睡眠模式,直到发送SRS的时刻,终端设备发送完SRS之后,终端设备可以进入深度睡眠模式。
例如,如图4和图5所示,该至少一个小区的TRS配置信息包括:gNB2的小区的TRS配置信息、gNB3的小区的TRS配置信息、gNB4的小区的TRS配置信息。终端设备在时刻1接入gNB1的小区,终端设备接收来自gNB1的TRS1,并通过TRS1实现与gNB1时频同步。终端设备处于微睡眠模式,直到发送SRS的时刻,终端设备发送SRS,以便于gNB1通过测量SRS实现对终端设备的定位。终端设备发送完SRS之后,终端设备可以进入深度睡眠模式。终端设备在时刻2从gNB1的小区重选到gNB2的小区。终端设备基于gNB2的小区的TRS配置信息接收gNB2的TRS2,并通过TRS2实现与gNB2时频同步。终端设备处于微睡眠模式,直到发送SRS的时刻,终端设备发送SRS,以便于gNB2通过测量SRS实现对终端设备的定位。终端设备发送完SRS之后,终端设备可以进入深度睡眠模式。对于终端设备在时刻3重选至gNB3的小区以及终端设备在时刻4重选至gNB4的小区的过程同样类似,具体不再一一说明。由此可知,通过本申请的技术方案,邻居小区为终端设备预配置邻居小区的TRS配置信息,并发送给网络设备。网络设备向终端设备发送该邻居小区的TRS配置信息。终端设备在重选至邻居小区之后,终端设备可以直接基于邻居小区的TRS配置信息接收TRS。因此,终端设备在重选到邻居小区之后,不需要向邻居小区请求邻居小区的TRS配置信息。所以终端设备无需从空闲态或未激活态切换至连接态,从而降低终端设备的功耗开销,提升终端设备的续航时间。
可选的,上述图2所示的实施例还包括步骤S206至步骤S208。步骤S206至步骤S208可以在步骤S202之后执行。
S206、当终端设备从第一小区重选至第二小区,且该至少一个小区的TRS配置信息不包括第二小区的TRS配置信息,终端设备接收第二小区的SSB。
具体的,终端设备可以通过第二小区的标识确定该至少一个小区的TRS配置信息中是否包括该第二小区的TRS配置信息。如果该至少一个小区的TRS配置信息中不包括该第二小区的TRS配置信息且终端设备重选至第二小区,终端设备可以接收第二小区的SSB,以便于终端设备与第二小区实现时频同步。
下面介绍该至少一个小区的TRS配置信息不包括第二小区的TRS配置信息的一些可能的情况。
情况1、网络设备向邻居小区请求为终端设备配置第二小区的TRS配置信息,邻居小 区拒绝为终端设备配置第二小区的TRS配置信息。例如,邻居小区没有空余的TRS资源可配置,邻居小区拒绝该网络设备的请求。
情况2、网络设备为终端设备的服务基站,该服务基站与邻居小区的基站之间没有建立Xn接口的连接。服务基站无法向邻居小区的基站发送TRS配置请求,导致服务基站无法向终端设备提供第二小区的TRS配置信息。
S207、终端设备基于第二小区的SSB进行时频跟踪。
例如,如图7所示,终端设备在时刻3重选至gNB5的小区,该至少一个小区的TRS配置信息不包括gNB5的小区的TRS配置信息。终端设备可以基于gNB5的小区的SSB5进行时频跟踪,以实现与gNB5的时频同步。
S208、终端设备发送SRS。
具体的,第二小区为第二接入网设备的小区,终端设备通过第二小区的SSB进行时频跟踪实现与第二小区时频同步之后,终端设备向第二接入网设备发送SRS,第二接入网设备测量SRS,以确定终端设备的位置。例如,如图7和图8所示,第二小区为gNB5的小区,终端设备从深度睡眠(deep sleep)模式切换到微睡眠(micro sleep)模式后,终端设备接收来自gNB5的SSB5,并通过SSB5进行时频跟踪以实现与gNB5的小区时频同步。终端设备处于微睡眠模式,直到发送SRS的时刻,终端设备发送完SRS之后,终端设备可以进入深度睡眠模式。
上述技术方案中,第二小区的TRS配置信息可以是参考终端设备的SRS配置信息配置的。也就是第二小区的TRS配置信息与终端设备的SRS配置信息具有关联。因此,终端设备通过第二小区的TRS实现时频同步的方案相对于终端设备通过小区的SSB实现时频同步的方案来说,终端设备在微睡眠模式下等待发送SRS的时长较短,有利于降低终端设备的功耗。并且,终端设备通过第二小区的TRS可以实现及时的进行时频同步,以便于终端设备发送SRS,使得第二小区能够在相应的SRS资源上接收到终端设备发送的SRS。避免由于时频偏差导致终端设备发送SRS的过程受到干扰或干扰其他终端设备的通信。
例如,如图7和图8所示,该至少一个小区的TRS配置信息包括:gNB4的小区的TRS配置信息。终端设备在时刻1接入gNB1的小区,终端设备接收来自gNB1的TRS1,并通过TRS1实现与gNB1时频同步。终端设备处于微睡眠模式,直到发送SRS的时刻,终端设备发送SRS,以便于gNB1通过测量SRS实现对终端设备的定位。终端设备发送完SRS之后,终端设备可以进入深度睡眠模式。终端设备在时刻2从gNB1的小区重选到gNB4的小区。终端设备基于gNB4的小区的TRS配置信息接收gNB4的TRS4,并通过TRS4实现与gNB4时频同步。终端设备处于微睡眠模式,直到发送SRS的时刻,终端设备发送SRS,以便于gNB4通过测量SRS实现对终端设备的定位。由此可知,邻居小区为终端设备预配置邻居小区的TRS配置信息,并向网络设备发送该邻居小区的TRS配置信息。网络设备向终端设备发送该邻居小区的TRS配置信息。终端设备在重选至邻居小区之后,终端设备可以直接基于邻居小区的TRS配置信息接收TRS。因此,终端设备在重选到邻居小区之后,不需要向邻居小区请求邻居小区的TRS配置信息。所以终端设备无需从空闲态或未激活态切换至连接态。从而降低终端设备的功耗开销,提高终端设备的续航时间。其次,该至少一个小区的TRS 配置信息可以是该至少一个小区参考终端设备的SRS配置信息配置的,也就是至少一个小区的TRS配置信息与SRS配置信息之间具有关联关系。例如,终端设备的SRS资源的周期是TRS资源的周期的整数倍,或者,SRS资源与TRS资源所位于的时隙或时域符号之间的时间间隔较小。例如,gNB4的小区的TRS配置信息,终端设备在通过TRS4实现时频同步之后,在短时间内可以发送SRS,发送完SRS之后进入深度睡眠模式。从而降低终端设备处于微睡眠模式的时间,实现低功耗定位,提升终端设备的续航时间。
终端设备发送完SRS之后,终端设备可以进入深度睡眠模式。终端设备在时刻3从gNB4的小区重选到gNB5的小区。终端设备接收来自gNB5的SSB5,并通过SSB5实现与gNB5的时频同步。终端设备处于微睡眠模式,直到发送SRS的时刻,终端设备发送SRS,以便于gNB5通过测量SRS实现对终端设备的定位。终端设备在时刻3从gNB5的小区重选到gNB6的小区。终端设备接收来自gNB6的SSB6,并通过SSB6实现与gNB6的时频同步。终端设备处于微睡眠模式,直到发送SRS的时刻,终端设备发送SRS,以便于gNB6通过测量SRS实现对终端设备的定位。由此可知,终端设备移动至第二小区,该至少一个小区的TRS配置信息不包括该第二小区的TRS配置信息。终端设备可以通过该小区的SSB实现时频同步。
本申请实施例中,终端设备接收来自网络设备的至少一个小区的TRS配置信息,终端设备处于第一小区,该至少一个小区是第一小区的邻居小区。当终端设备从第一小区重选至第二小区,且该至少一个小区的TRS配置信息包括第二小区的TRS配置信息,终端设备基于第二小区的TRS配置信息接收第二小区的TRS。由此可知,终端设备先接收来自网络设备的第二小区的TRS配置信息。便于终端设备从第一小区重选至第二小区之后,终端设备可以基于第二小区的TRS配置信息接收第二小区的TRS。终端设备无需从空闲态或未激活态切换至连接态,以获取邻居小区的服务基站为该终端设备配置的TRS配置信息。从而降低终端设备的功耗开销,提升终端设备的续航时间。
下面结合图3所示的实施例介绍定位设备获取第二小区的TRS配置信息的过程以及定位设备向终端设备发送第二小区的TRS配置信息的过程。
图3为本申请实施例通信处理方法的另一个实施例示意图。请参阅图3,通信处理方法包括:
S301、定位设备向第二接入网设备发送第一定位信息请求消息。相应的,第二接入网设备接收来自定位设备的第一定位信息请求消息。

例如,如图4和图5所示,终端设备接入gNB1的小区,终端设备通过gNB1的小区的TRS配置信息接收来自gNB1的TRS1,并通过TRS1实现时频同步之后,终端设备在短时间内可以发送SRS,在发送完SRS之后终端设备进入深度睡眠模式,从而实现终端设备的低功耗定位,降低终端设备的功耗开销。也就是说第一接入网设备参考终端设备的SRS配置信息配置第一小区的TRS配置信息,使得SRS资源与TRS资源之间关联,有利于终端设备降低功耗开销。在定位区域内终端设备的SRS资源是共享的,也就是终端设备在定位区域内的不同小区采用的SRS资源是相同的(SRS资源包括终端设备用于发送SRS的时频资源,在图5的示例中仅示出了终端设备在不同的小区内用于发送SRS的时域资源是相同的,实际上终端设备在不同的小区内用于发送SRS的频域资源也是相同的),因此定位设备向第二接入网设备发送第一小区的TRS配置信息。有利于第二接入网设备为终端设备配置与终端设备的SRS配置信息关联的第二小区的TRS配置信息,从而进一步降低功耗开销,提升终端设备的续航时间。
实现方式3、第一定位信息请求消息包括SRS资源预留信息和第二指示信息。

2、基于上述步骤S301的实现方式2,第二接入网设备参考第一推荐TRS配置信息配置第二小区的TRS配置信息。
可选的,第一推荐TRS配置信息包括第一小区的TRS配置信息中的部分或全部信息。第二接入网设备参考第一推荐TRS配置信息配置第二小区的TRS配置信息。例如,第二接入网设备可以将第一推荐TRS配置信息作为第二小区的TRS配置信息。在定位区域内终端设备在不同的小区内的SRS资源是共享的,也就是终端设备在定位区域内的不同小区采用的SRS资源是相同的。结合上述步骤S301a和步骤S301b可知,定位设备向第二接入网设备发送第一小区的TRS配置信息,有利于第二接入网设备参考第一小区的TRS配置信息为终端设备配置与终端设备的SRS配置信息关联的第二小区的TRS配置信息,从而进一步降低功耗开销。第二接入网设备向定位设备发送第一定位信息响应消息。第一定位信息响应消息包括第二小区的TRS配置信息。
例如,如图4和图5所示,终端设备在时刻2重选到gNB2的小区,终端设备通过gNB2的小区的TRS配置信息接收来自gNB2的TRS2,并通过TRS2实现时频同步之后,终端设备在短时间内可以发送SRS,在发送完SRS之后终端设备进入深度睡眠模式,从而实现终端设备的低功耗定位,降低终端设备的功耗开销。也就是说第二接入网设备参考第一小区的TRS配置信息配置第二小区的TRS配置信息,使得SRS资源与TRS资源关联,有利于终端设备降低功耗开销。
3、基于上述步骤S301的实现方式3,第二接入网设备根据第二指示信息参考SRS资源预留信息配置第二小区的TRS配置信息。
具体的,SRS资源预留信息包括终端设备的SRS资源的配置信息。例如,SRS资源预留信息包括终端设备的SRS资源所在的时频位置。第二接入网设备通过该SRS资源预留信息为终端设备预留SRS资源。第二接入网设备可以根据第二指示信息配置与该SRS资源关联的第二小区的TRS配置信息。然后第二接入网设备向定位设备发送第一定位信息响应消息。第一定位信息响应消息包括第二小区的TRS配置信息。以便于定位设备向终端设备发送该第二小区的TRS配置信息。基于实现方式3,第二小区的TRS配置信息与SRS资源预留信息对应的SRS资源关联。有利于进一步降低终端设备的功耗开销。

本申请还提供一种通信装置。请参阅图11,图11为本申请实施例通信装置的一个结构示意图。通信装置1100可以用于执行图3所示的实施例中第一接入网设备执行的步骤,具体请参考上述方法实施例中的相关介绍。
通信装置1100包括收发模块1101和处理模块1102。
收发模块1101,用于接收来自定位设备的第二定位信息请求消息,通信装置1100为第一小区的接入网设备,终端设备处于第一小区,第二定位信息请求消息包括第三指示信息,第三指示信息用于指示通信装置1100参考终端设备的SRS配置信息配置终端设备的第一小区的TRS配置信息;

本申请还提供一种通信装置。请参阅图12,图12为本申请实施例通信装置的一个结构示意图。通信装置1200可以用于执行图3所示的实施例中第二接入网设备执行的步骤,具体请参考上述方法实施例中的相关介绍。

上述技术方案中,定位设备指示通信装置1200配置第二小区的TRS配置信息。处理模块1202为终端设备预配置第二小区的TRS配置信息.收发模块1201向定位设备发送该第二小区的TRS配置信息。这样,当终端设备重选至第二小区时,终端设备可以直接基于第二小区的TRS配置信息接收第二小区的TRS。终端设备无需从空闲态或未激活态切换至连接态,以获取第二小区的服务基站为该终端设备配置第二小区的TRS配置信息。避免终端设备重选至第二小区后切换至连接态导致终端设备的功耗增加的问题,从而降低终端设备的功耗开销,提升终端设备的续航时间。进一步的,第二接入网设备可以配置与终端设备的SRS配置信息关联的第二小区的TRS配置信息。终端设备进入微睡眠模式,终端设备基于第二小区的TRS配置信息接收TRS并进行时频同步之后,可以在短时间内发送SRS。终端设备发送SRS之后可以进入深度睡眠模式。在深度睡眠模式下,终端设备只需要维持极低的时钟电流。从而减少了终端设备处于微睡眠模式的时间,降低了终端设备的功耗开销,提升终端设备的续航时间。
可选的,上述图12所示的通信装置1200还可以用于执行图6所示的实施例中的第二接入网设备执行步骤。具体的,图12所示的通信装置1200可以执行以下方案:

上述技术方案中,第一接入网设备指示通信装置1200配置参考第二TRS推荐配置信息 配置第二小区的TRS配置信息。处理模块1202根据第四指示信息参考第二TRS推荐配置信息为终端设备预配置第二小区的TRS配置信息。收发模块1201向第一接入网设备发送第二小区的TRS配置信息。这样,当终端设备重选至第二小区时,终端设备可以直接基于第二小区的TRS配置信息接收第二小区的TRS。终端设备无需从空闲态或未激活态切换至连接态,以获取第二小区的服务基站为该终端设备配置第二小区的TRS配置信息,从而降低终端设备的功耗开销。避免终端设备重选至第二小区后切换至连接态导致终端设备的功耗增加的问题,从而降低终端设备的功耗开销,提升终端设备的续航时间。
