本申请涉及通信领域,并且更具体地,涉及一种物理信道监测方法和终端设备。
背景技术
通常,在工作于非授权频谱的新空口NR-U(NR based access to Unlicensed spectrum)系统中,终端在一个服务小区上可以被配置两个搜索空间组(search space group,SS group),有时也将搜索空间组称为搜索空间集合组(search space sets group,SSS group),用于监测物理下行控制信道PDCCH。
对于确定配置了两个搜索空间SS组的情况,在一段时间内,终端确定需要对该两个SS组中的一个SS组中的PDCCH进行监测(PDCCH monitoring)。目前,在一个服务小区上,终端可支持从基于第一组标识对应的搜索空间集合监测PDCCH切换到基于第二组标识对应的搜索空间集合监测PDCCH,反之亦然。但是,对于多个服务小区组中的一个服务小区组,如何确定终端在该服务小区组中的多个服务小区上的搜索空间组的切换行为,是目前需要研究的问题。

为了清楚地阐述本申请实施例的思想,首先对通信系统中一个服务小区上的搜索空间组切换的处理过程进行简要描述。本申请实施例包括以下内容中的至少部分内容。
在通信系统例如NR-U系统中,为UE配置搜索空间SS时,搜索空间对应的配置参数中可以包括搜索空间组标识ID参数,例如searchSpaceGroupIdList-r16,如果UE被配置搜索空间组ID参数,那么该搜索空间组ID参数可指示该搜索空间包括以下三种情况中的一种:
①该搜索空间对应的搜索空间组标识为第一组标识,例如该搜索空间对应组0,或者,该搜索空间属于组0;
②该搜索空间对应的搜索空间组标识为第二组标识,例如该搜索空间对应组1,或者,该搜索空间属于组1;
③该搜索空间对应的搜索空间组标识既对应于第一组标识,也对应于第二组标识,例如该搜索空间对应组0和组1,或者,该搜索空间既属于组0也属于组1。
可选地,UE可以被配置搜索空间切换组指示参数。如果UE被提供搜索空间切换组指示参数,例如searchSpaceSwitchingGroupList-r16,该参数指示一个或多个服务小区组,对于该一个或多个服务小区组中的一个服务小区组,UE在进行PDCCH监测时,在该服务小区组中的所有小区上的SS组的切换行为都是相同的;否则,如果UE被提供搜索空间组ID参数,那么UE在进行PDCCH监测时,仅针对该服务小区上的SS组进行SS组的切换。
可选地,UE可被提供一个定时器,该定时器的取值的计时单位可以为时隙。例如,当定时器启动后,每经过一个时隙,定时器的取值减去1。该定时器的取值可以是高层配置的,例如可以通过高层参数searchSpaceSwitchingTimer-r16提供。
UE进行搜索空间SS组切换可采用显式切换的方式实现,或可以采用隐式切换的方式实现。
关于显式切换,终端设备可在下行控制信息(Downlink control information,DCI)格式2_0中被配置用于指示SS组切换的切换指示信令,终端设备还可根据检测(detect)到的DCI格式2_0中的切换指示信令的指示来进行SS组的切换。关于隐式切换,终端设备可根据是否在例如第一组标识对应的SS集合中检测到DCI,来确定是否切换到例如第二组标识对应的SS集合。
以下基于图2、图3和图4,对一个服务小区上的隐式切换的方式做进一步详细描述。对于一个服务小区,如果UE没有被提供切换指示信令,例如在DCI格式2_0中UE没有被网络设备提供或没有被网络设备配置该服务小区对应的SearchSpaceSwitchTrigger-r16参数,和/或该服务小区不属于任何服务小区组,那么在该服务小区上,SS组的切换过程可包括以下情况中的至少一种:
1)参考图2,如果UE在根据第一组标识对应的一个搜索空间集合进行PDCCH监测时检测到一个DCI格式,那么从携带该DCI格式的PDCCH的最后一个符号后的至少P个符号后的第一个时隙开始,UE根据第二组标识对应的搜索空间集合进行PDCCH监测,并停止根据第一组标识对应的搜索空间集合进行PDCCH监测。
2)如果UE在任意搜索空间集合中进行PDCCH监测时检测到一个DCI格式,那么UE设置或重设定时器为高层参数例如searchSpaceSwitchingTimer-r16配置的值。
3)参考图3,如果UE根据SS组1中的搜索空间集合进行PDCCH监测,那么从定时器过期的时隙后的至少P个符号后的第一个时隙开始,UE根据第一组标识对应的搜索空间集合进行PDCCH监测,并停止根据第二组标识对应的搜索空间集合进行PDCCH监测。
4)参考图4,如果UE被配置监测DCI格式(例如DCI格式2_0),从DCI格式指示的该服务小 区的剩余信道占用时间COT的最后一个符号后的至少P个符号后的第一个时隙开始,UE根据第一组标识对应的搜索空间集合进行PDCCH监测,并停止根据第二组标识对应的搜索空间集合进行PDCCH监测。
可选地,如果存在上述3)和4)的条件,那么UE根据第一组标识对应的搜索空间集合进行PDCCH监测,并停止根据第二组标识对应的搜索空间集合进行PDCCH监测的时隙包括上述3)和4)中先开始的时隙。
然而,如果UE被提供搜索空间切换组指示参数例如UE被网络设备配置参数searchSpaceSwitchingGroupList-r16,该参数指示至少一个服务小区组,那么对于该至少一个服务小区组中的一个服务小区组,UE在进行PDCCH监测时,在该服务小区组中包括的所有小区上的SS组的切换行为都可以是相同的。但是,在隐式切换方式下,如何确定一个服务小区组中的所有小区上的搜索空间SS组的切换行为,有待进一步明确和优化。
为此,本申请实施例提供一种物理信道监测方法,参考图5,该方法应用于终端设备,该方法包括:
S101,终端设备被配置至少一个服务小区组;
S102,所述终端设备在第一服务小区上根据第一服务小区组进行物理信道监测;其中,所述第一服务小区是所述第一服务小区组中包括的服务小区,所述第一服务小区组是所述至少一个服务小区组中的服务小区组。
可选地,该物理信道包括控制信道。具体地,该控制信道包括PDCCH。
可选地,该物理信道可以包括终端设备和终端设备之间传输的物理信道,例如终端设备和终端设备之间传输的控制信道;或,该物理信道可以包括网络设备和网络设备之间传输的物理信道,例如网络设备和网络设备之间传输的控制信道。
应理解,在本申请实施例中,物理信道监测以PDCCH监测为例进行说明。如果待监测的物理信道包括其他物理信道,那么将PDCCH替换为对应的物理信道即可。本申请对此不再赘述。
利用本申请的实施例,如果终端设备被配置至少一个服务小区组,则对于该至少一个服务小区组中的第一服务小区组,以及该第一服务小区组中的第一服务小区,该终端设备在该第一服务小区上根据该第一服务小区组进行PDCCH监测,由此,能够确定终端设备在一个服务小区组中的所有小区上的搜索空间SS组的切换行为。
应理解,在本申请实施例中,服务小区也可以称为小区。搜索空间也可以称为搜索空间集合。搜索空间组也可以称为搜索空间集合组。
可选地,在本申请实施例中,终端设备在第一服务小区上进行PDCCH监测,包括:终端设备在第一服务小区的下行激活带宽部分(Bandwidth part,BWP)上进行PDCCH监测。
可选地,在本申请实施例中,对于第一服务小区,终端设备被配置的搜索空间SS集合中包括搜索空间组标识,包括:在第一服务小区的BWP上,终端设备被配置的搜索空间SS集合中包括搜索空间组标识。可选地,对于同一个服务小区中的不同BWP上的SS集合是独立配置的,因此同一个服务小区中的不同BWP上,可能被配置的SS集合组个数相同,也可能被配置的SS集合组个数不同。例如,假设第一服务小区中包括第一BWP和第二BWP,那么可以是第一BWP和第二BWP上都包括两个SS集合组例如组0和组1;或,第一BWP上包括两个SS集合组例如组0和组1,第二BWP上包括一个SS集合组例如组0;或,第一BWP上包括两个SS集合组例如组0和组1,第二BWP上不包括SS集合组;或,第一BWP上包括一个SS集合组例如组0,第二BWP上不包括SS集合组。
在对本申请实施例的多种实施方式进行详细描述之前,首先对服务小区组中的多个小区上的SS组的切换进行简要描述。如果终端设备被配置按服务小区组进行PDCCH监测,例如终端设备被提供搜索空间切换组指示参数例如searchSpaceSwitchingGroupList-r16,该参数指示一个或多个服务小区组,那么对于该一个或多个服务小区组中的第一服务小区组,终端设备可以根据该第一服务小区组对该第一服务小区组中包括的至少一个小区进行PDCCH监测。可选地,终端设备在该第一服务小区组中的至少两个小区上的SS组的切换行为是相同的。可选地,终端设备在该第一服务小区组中的所有小区上的SS组的切换行为都是相同的。
可选地,第一服务小区组可为该一个或多个服务小区组中的任意一个服务小区组。可选地,一个小区最多可以被配置属于一个服务小区组。例如,一个小区不能同时属于两个或两个以上的服务小区组。又例如,一个小区可以被配置属于一个服务小区组,也可以不属于任何服务小区组。可选地,对于属于第一服务小区组的小区,终端设备在该小区上进行PDCCH监测时,SS组监测切换行为和该第一服务小区组中的其他小区的SS组监测切换行为一致。
可选地,对于一个搜索空间集合,如果该搜索空间集合对应的配置参数中不包括搜索空间组标识ID参数,那么UE需要根据该搜索空间集合进行PDCCH监测。或者说,如果一个搜索空间集合不对应 任何组标识,那么UE需要根据该搜索空间集合进行PDCCH监测。
可选地,对于一个搜索空间集合,如果该搜索空间集合对应的搜索空间组标识既包括第一组标识也包括第二组标识,那么UE在根据第一组标识或第二组标识对应的搜索空间集合进行PDCCH监测时,都包括根据该搜索空间集合进行PDCCH监测。
在不同的情况下,本申请实施例的终端设备在第一服务小区上根据第一服务小区组进行PDCCH监测的处理过程不同,均能够实现对服务小区组中的至少一个小区上的搜索空间SS组的切换。以下通过多个实施例分别进行详细描述。
实施例1
在本实施方式中,终端设备在第一服务小区上根据第一组标识对应的搜索空间SS集合进行PDCCH监测,其中,如果终端设备在第一服务小区组中的第二服务小区上根据第一组标识对应的SS集合检测到第一DCI格式,则从第一服务小区上的第一时隙开始,终端设备在第一服务小区上根据第二组标识对应的SS集合,进行PDCCH监测,并停止根据第一组标识对应的SS集合进行PDCCH监测。
