图2是根据一示例性实施例示出的通信方法的流程示意图,如图2所示,本示例的通信方法适用于网络设备侧,网络设备可以包括基站、中继站或射频拉远单元等接入网络设备,具体包括以下处理步骤:
步骤201,发送参考信号的资源配置信息。
其中,所述参考信号对一个寻呼帧(Paging Frame,PF)内的所有寻呼时机(Paging Occasion,PO)或部分PO有效,也即,本公开实施例中,网络设备所配置的参考信号对PF内的全部个PO有效,或仅对某个PO或某些PO有效。具体地,可以由网络设备实现对PO是否有效进行配置,或由网络协议来实现对PF内PO是否有效的配置。
本公开实施例中,所述参考信号的资源配置信息包括:承载所述参 考信号的时频位置信息;所述时频位置为相对于PF/PO起点的偏置信息。为了简化所述参考信号的配置,本公开实施例通过参考信号相对于PF/PO起点的偏置信息来进行指示,以方便UE能尽快解析出所述参考信号的承载时频位置,以便进行监听而进行同步。本公开实施例中,虽然记载了PF/PO起点,但对于本领域技术人员而言,PF/PO起点仅是一参考时间点,也可以是其他的参考时间点的偏置信息,如可以是其他通知消息帧的起始或结束时间点等。
作为一种实现方式,网络设备在确定承载所述参考信号的时频位置信息时,需要接收UE上报的UE所支持的参考信号到PF/PO之间的最小偏置,即网络设备需要根据海量的UE上报自身所支持的参考信号到PF/PO之间的最小偏置来对所述参考信号的时频位置进行配置,以使UE能基于自身能力能够在合适的时刻醒来监听所述参考信号。具体地,网络设备确定UE的能力信息中,解调参考信号时所支持的参考信号到PF/PO之间的最小偏置;基于UE的参考信号到PF/PO之间的最小偏置,确定偏置值。
作为一种实现方式,网络设备基于所述最小偏置确定所述时频位置;其中,所述时频位置相对于PF/PO起点的偏置大于或等于所述最小偏置。也即,网络设备需要根据UE所支持的参考信号到PF/PO之间的最小偏置,所设置的所述参考信号的时频位置信息,能够使UE在自身的能力范围内监听到参考信号,因此,此时需要根据UE上报的参考信号到PF/PO之间的最小偏置中的最大值来设置所述参考信号的时频位置信息,使所配置的所述参考信号的时频位置信息到PF/PO之间的偏置大于所有UE支持的参考信号到PF/PO之间的最小偏置中的最大值,从而能保证所有UE都能在DTX接收模式下正常监听所述参考信号。
作为一种实现方式,网络设备可以基于通信协议获取UE所支持的参 考信号到PF/PO之间的最小偏置。也就是说,当UE所支持的参考信号到PF/PO之间的最小偏置如果通过协议被配置,则网络设备可以基于通信协议获取到UE所支持的参考信号到PF/PO之间的最小偏置。或者,网络设备可以接收UE自行上报的UE所支持的参考信号到PF/PO之间的最小偏置,此时,UE可以基于上行消息实现UE所支持的参考信号到PF/PO之间的最小偏置的上报。或者,网络设备也可以接收其他网络设备发送的UE所支持的参考信号到PF/PO之间的最小偏置。这里的其他网络设备可以是核心网侧的相关网络设备,例如,可以通过核心网实现向接入侧网络设备发送UE所支持的参考信号到PF/PO之间的最小偏置的通知。
作为一种实现方式,网络设备接收DRX场景下UE所支持的参考信号到PF/PO之间GAP的能力信息;或,接收针对UE所支持的参考信号到PF/PO之间的GAP的能力信息。
本公开实施例中,所述发送参考信号的资源配置信息中还包括发送周期的信息,所述发送周期包括以下之一:10ms、20ms、40ms、80ms、160ms。
在一些实施例中,所述发送参考信号的资源配置信息中的发送周期与寻呼帧周期绑定时,所述发送参考信号的资源配置信息中不包括发送周期的信息。此时,通过寻呼帧周期的倍数隐式地指示所述发送参考信号的资源配置信息的发送周期。作为一种示例,所述发送参考信号的资源配置信息中不包括发送周期的信息,所述发送周期和寻呼帧密度存在对应关系:
oneT,halfT,quarterT,oneEighthT,oneSixteenthT,分别对应于发送周期的10ms,20ms,40ms,80ms,160ms。这里仅是示例性地给出了一种实现方式,本领域技术人员应当理解,也可以采用其他指示符来表 达对应的指示信息,作为一种示例,也可以用倒置的指示信息分别指示上述的发送周期等。
本公开实施例中,所述发送参考信包括以下至少之一:追踪参考信号(Tracking Refernece Signal,TRS)、小区参考信号(Cell Reference Signal,CRS)。
本公开实施例中,当基站未下发TRS/CRS的资源配置信息时,UE仍然按照原来的同步方式,基于监听SSB进行同步。
图3是根据一示例性实施例示出的通信方法的流程示意图,如图3所示,本示例的通信方法适用于网络设备侧,网络设备可以包括基站、中继站或射频拉远单元等接入网络设备,具体包括以下处理步骤:
步骤301,确定SSB配置密度超出第一设定阈值时,不发送TRS。
这里,当SSB的配置密度较大时,UE完全可以基于SSB同步,无需配置TRS。
具体地,在SSB配置周期和寻呼帧间隔相同或者小于寻呼帧间隔且PF配置位置和SSB较为靠近,不配置TRS。
即当在SSB配置周期和寻呼帧间隔相同或者小于寻呼帧间隔且PF配置位置和SSB之间的间隔较小如小于第二设定阈值的情况下,则无需配置TRS。这里的第二设定阈值可以是5ms、10ms或15ms等。
作为一种实现方式,当网络设备确定SSB的配置周期为5ms或10ms,不发送TRS的资源配置信息;或
确定SSB配置周期不大于寻呼帧间隔且PF与SSB之间的间隔小于第二设定阈值时,不发送TRS的资源配置信息;这里的第二设定阈值可以是5ms、10ms或15ms等。
作为一种实现方式,当网络设备确定寻呼搜索空间pagingSearchSpace指示为0、复用模式为模式2或3时,不发送TRS的资源配置信息。
作为一种实现方式,当网络设备确定寻呼搜索空间pagingSearchSpace指示为0、复用模式为模式2或3时,且PF配置位置和SSB之间的间隔较小如小于第二设定阈值的情况下不发送TRS的资源配置信息。
图4是根据一示例性实施例示出的通信方法的流程示意图,如图4所示,本示例的通信方法适用于UE,具体包括以下处理步骤:
步骤401,将所支持的参考信号与PF/PO之间的最小偏置向网络设备发送。
本公开实施例中,UE将自身所支持的解调参考信号时的参考信号与PF/PO之间的最小偏置向网络设备发送,以方便网络设备基于UE所支持的参考信号与PF/PO之间的最小偏置确定参考信号的时频资源,并将网络设备所配置的参考信号的时频资源信息尽快向UE进行通知。
本公开实施例中,UE在向网络设备发送完自身所支持的参考信号与PF/PO之间的最小偏置信息后,将接收网络设备发送的参考信号的资源配置信息,以便基于参考信号的资源配置信息监听参考信号,以便对相应的PO进行监听,以便发起相应的随机接入。
UE接收所述网络设备发送的参考信号的资源配置信息,所述参考信号的资源配置信息包括承载所述参考信号的时频位置信息;本公开实施例中,网络设备所配置的所述时频位置为相对于PF/PO起点的偏置信息。
本公开实施例中,UE确定所述网络设备配置的所述参考信号的相对于PF/PO起点的偏置与所述UE支持的参考信号到PF/PO之间的偏置相同时,按照所述偏置值醒来,基于所述参考信号进行时频域同步。
作为一种实现方式,当UE确定所述网络设备配置的所述参考信号的相对于PF/PO起点的偏置大于所述UE支持的参考信号到PF/PO之间的偏置时,按照所述网络设备配置的偏置值醒来,基于所述参考信号进行时频域同步。
作为一种实现方式,当UE确定所述网络设备配置的所述参考信号的相对于PF/PO起点的偏置小于所述UE支持的参考信号到PF/PO之间的偏置时,
采用持续监听方式监听所述参考信号;或
接收所述网络设备重新配置的所述参考信号的相对于PF/PO起点的第二偏置;或
按照所述UE支持的参考信号到PF/PO之间的偏置监听所述参考信号;
基于所述参考信号进行时频域同步。
本公开实施例中,UE还向所述网络设备发送所支持的DRX的GAP的能力信息;或UE向所述网络设备发送UE针对Long DRX和Short DRX所支持的GAP的能力信息。以便网络设备基于GAP确定参考信号的资源配置信息。
在一些实施例中,所述发送参考信号的资源配置信息中还包括发送周期的信息,所述发送周期包括以下之一:
10ms、20ms、40ms、80ms、160ms。
在一些实施例中,所述发送参考信号的资源配置信息中的发送周期与寻呼帧周期绑定时,所述发送参考信号的资源配置信息中不包括发送周期的信息。
在一些实施例中,所述发送参考信号的资源配置信息不包括发送周期的信息,所述发送周期和寻呼帧密度存在对应关系:
oneT,halfT,quarterT,oneEighthT,oneSixteenthT,分别对应于发送周期的10ms,20ms,40ms,80ms,160ms。
在一些实施例中,所述发送参考信包括以下至少之一:
追踪参考信号(Tracking Refernece Signal,TRS)、小区参考信号(Cell Reference Signal,CRS)。
本公开实施例中,当基站未下发TRS/CRS的资源配置信息时,UE仍然按照原来的同步方式,基于监听SSB进行同步。
本公开实施例通过在空闲态使用连接态的TRS/CRS来辅助UE进行获取和网络的时频域同步,相比于SSB同步,TRS/CRS配置可以配置距离PO更近,可以更晚醒过来,因此可以更加省电。本公开实施例正是针对TRS/CRS配置方式,针对PF和/或PO进行TRS/CRS的偏置配置,以减少信令开销,以及降低配置复杂度。以网络设备为基站为例,进一步阐明本公开实施例的技术方案。
基站下发的TRS/CRS的资源针对一个PF内的所有PO或部分PO生效。即PF内的多个PO或某个共用相同TRS/CRS资源配置进行时频域同步。其中,基站下发的TRS/CRS的资源的时域位置为相对于PF帧起点或者PO的偏置(offset);基站参考UE的支持的TRS/CRS到PF/PO之间的最小offset进行TRS/CRS资源时域位置相对于PF帧/PO起点的offset配置,并下发给UE;其中,UE支持的TRS到PF/PO之间的最小offset为协议规定或者UE在连接态时提前上报给基站或者基站从核心网获取,作为基站配置TRS/CRS的资源的时域位置的参考。作为一种实现方式,UE可以针对DRX/eDRX上报一个能力配置gap;作为另一种实现方式,UE可以针对eDRX场景,上报了GAP指示能力,Long DRX类型的gap以及short DRX类型的gap,用于在配置eDRX场景中eDRX的Gap,以用于寻呼时间窗口(Paging Time Window,PTW)内的第一个PF/PO,也可以用于在配置eDRX场景中DRX的Gap用于PTW内其他PF/PO。
本公开实施例中,基站下发给UE的TRS/CRS资源时域位置相对于PF帧/PO起点的offset配置可能和UE支持的能力不相同:UE需要按照规则确定监听TRS/CRS监听时刻。或者,基站下发给UE的TRS/CRS资源时域位置相对于PF帧/PO起点的offset配置和UE支持值相同,则UE按照该值 提前醒来和TRS/CRS资源配置进行时频域同步。
作为一种示例,下发给UE的TRS/CRS资源时域位置相对于PF帧/PO起点的offset大于UE支持值,则UE采用持续监听方式监听所述参考信号,此时,由于UE所支持的TRS/CRS相对于PF帧/PO起点的offset大于网络设备所配置的TRS/CRS相对于PF帧/PO起点的offset,此时已超出UE的监听能力,这种情况下,UE放弃DTX方式,持续监听TRS/CRS;或UE接收所述网络设备重新配置的所述参考信号的相对于PF/PO起点的第二偏置,作为一种示例,所述第二偏置可以为不小于所述UE支持的参考信号到PF/PO之间的偏置,此时UE可以基于所述第二偏置监听TRS/CRS;当然,所述第二偏置也可以仍然是小于所述UE支持的参考信号到PF/PO之间的偏置。作为一种实现方式,UE也可以按照所述UE支持的参考信号到PF/PO之间的偏置监听所述参考信号,并基于所述参考信号进行时频域同步。此时,UE可能会错过所述参考信号。本公开实施例中,基站下发的TRS/CRS的资源的周期即取值为{10ms,20ms,40ms,80ms,160ms}。
本公开实施例中,当网络设备将TRS/CRS周期和寻呼帧周期进行绑定时,此时基站即不用下发TRS/CRS周期配置。具体地,基站可以向UE发送oneT,halfT,quarterT,oneEighthT,oneSixteenthT等指示信息,oneT,halfT,quarterT,oneEighthT,oneSixteenthT的指示信息分别对应指示参考信号的发送周期10ms,20ms,40ms,80ms,160ms。
作为一种实施例,SSB配置周期=5ms,不需要TRS;作为一种实施例,SSB配置周期=10ms,不需要TRS;作为一种实施例,在SSB配置周期和寻呼帧间隔相同或者小于寻呼帧间隔且PF配置位置和SSB较为靠近,则无需TRS,比如PF为紧挨着SSB的下一个无线帧。作为一种实施例,当pagingSearchSpace=0,复用模式为模式2或模式3时,则无需TRS。也就是说,当寻呼帧密度比SSB配置周期更加稀疏,每个寻呼PF总能找到对应 的SSB,且PF和SSB是频分复用时,则无需再发送TRS,也无需TRS的配置信息。
本公开实施例中,当基站未下发TRS/CRS的资源配置信息时,UE仍然按照原来的同步方式,基于监听SSB进行同步。
