Description

一种配置非连续接收周期的方法、终端及存储介质 技术领域
本申请涉及通信技术领域,尤其涉及一种配置非连续接收周期的方法、终端及存储介质。
背景技术
在基于OFDM的全新空口设计的全球性5G标准5G New Radio(新空口,NR),以及长期演进(Long Term Evolution,LTE)通信系统中,会通过混合自动重传请求(Hybrid Automatic Repeat reQuest,HARQ)机制保证数据的传输。对于用户设备与基站之间的通信Uu链路,基站可以发送物理下行控制信道(Physical Downlink Control Channel,PDCCH)信息并指示物理下行共享信道(Physical Downlink Shared Channel,PDSCH)或者直接发送PDSCH,用户设备(User Equipment,UE)根据接收到的数据在基站调度的上行资源上向基站上报是否正确接收PDSCH的HARQ-ACK信息。HARQ-ACK信息包括2种,确认应答(Acknowledgement,ACK)和否定应答(Negative Acknowledgement,NACK),当UE收到并成功解析出PDSCH则发送ACK信息;当UE收到PDCCH但并未成功解析出PDSCH或者没有收到PDSCH时,则发送NACK,此时,基站收到NACK后会重新发送PDSCH。如果UE未收到已下发的用于调度PDSCH的下行PDCCH或者下行PDCCH解析不正确,则UE并不上报任何反馈信息,基站未收到信息则认为UE处于非连续发信(Discontinuous Transmission,DTX)状态,同样也会重新发送PDSCH。
在5G侧链路通信系统中,HARQ机制也同样会应用于侧链路通信。第一终端向第二终端发送物理侧行共享信道(Physical Sidelink Shared Channel,PSSCH)和物理侧行控制信道(Physical Sidelink Control Channel,PSCCH)之后,第二终端会在物理侧行反馈信道(Physical Sidelink Feedback Channel,PSFCH)上向第一终端反馈HARQ信息以确认是否收到或者解出第一终端发送的PSSCH。侧链路通信的传播类型包含单播、组播以及广播。在单播和组播场景下,如果使能HARQ反馈后,第二终端都需要向第一终端反馈HARQ信息,也就是说在组播场景下的第二终端可以大于一个。在资源分配模式下,侧链路的资源都是由基站来进行分配,此时,第一终端还需要将HARQ信息上报给基站,以获得侧链路上重传PSCCH和PSSCH的资源。
非连续接收(Discontinuous Reception,DRX)机制的引入是为了降低UE功耗,延长电池寿命。如图1所示,在时域上可化分成一个个连续的非连续接收周期DRXcycle。该非连续接收周期DRX cycle可包括激活期On Duration和休眠期opportunity for DRX。在激活期,终端可以正常接收信道和信号;在休眠期,终端将不接收检测信道或信号,以保持低功耗状态。在NR Uu链路中,在激活期状态下,UE监听并接收PDCCH;在休眠期,UE不接收PDCCH以减少功耗。
现有技术中,用户设备在休眠期则不接收PDCCH,且用户设备的非连续接收周期DRX cycle由基站指示,用户设备不能自己调整。这样导致在休眠期,用户设备对所有的侧链路信道都不接收,比如反馈信道。且,对于各个非连续接收周期DRX cycle配置不同的用户设备,各自所处的激活期的时间可能不同,这将导致设备之间通信受阻。

具体实施方式
为了使本技术领域的人员更好地理解本申请方案,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的实施例,而不是全部的实施例。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,都应当属于本申请保护的范围。
现有技术中,终端在处于非连续接收DRX的休眠期时,虽然可以通过不接收任何信道或者信号来达到节省功耗的目的,但是侧链路中UE仍然需要通过接收PSCCH来进行资源感知和选择,也需要通过接收PSFCH来确定所发送数据是否被正确接收,以便判断是否需要重传该数据。为此,本申请实施例提供在侧行SL通信中,DRX有多种不同的状态,用于表示在DRX休眠期不接收或者接收哪些信道或者信号。其中,通过设定多种状态,只接收特定信道或者信号可以达到功耗和系统性能的平衡,提高资源感知的准确性,降低不同用户设备UE资源碰撞的概率;另一方面可以减少因为DRX造成的PSFCH漏检,避免非必要的重传,降低时延,提高系统可靠性。
下面介绍本方案提供的不同状态的DRX。
其中,如表一所示为不同状态下的DRX在休眠期接收检测的信道/信号:
表一
DRX状态 休眠期不接收检测信道/信号 休眠期接收检测信道/信号
状态一 PSCCH+PSSCH+PSFCH --
状态二 PSCCH+PSSCH PSFCH
状态三 PSSCH+PSFCH PSCCH
状态四 PSSCH PSCCH+PSFCH
其中,上述仅以四种状态为例进行说明,上述DRX状态还包括其他状态,如状态五,休眠期接收检测信道/信号PSSCH+PSCCH;或者,状态六,PSSCH+PSFCH等等,本方 案对此不做具体限定。
进一步地,本方案还提供可根据接收检测信道类型来定义不同的功率模式确定终端处于哪一种节能模式,如表二所示。
表二
节能状态 不接收检测信道/信号 接收检测信道/信号
状态一 PSCCH+PSSCH+PSFCH --
状态二 PSCCH+PSSCH PSFCH
状态三 PSSCH+PSFCH PSCCH
状态四 PSSCH PSCCH+PSFCH
其中,表二仅以上述四种状态为例进行说明。上述节能状态还可以包括状态五,不接收检测信道/信号PSCCH+PSFCH;状态六,不接收检测信道/信号PSCCH;状态七,不接收检测信道/信号PSFCH等,本方案对此不做具体限定。
另一方面,本方案还提供可根据接收检测信道数量来定义不同的功率模式确定终端处于哪一种节能模式,如表三所示。
表三
节能状态 接收检测信道/信号 信道数量
状态一 PSCCH X1
状态二 PSCCH X2
其中,上述X1、X2均为正整数,且X1不等于X2。上述仅以接收检测信道/信号为PSCCH为例进行说明,其接收检测信道/信号还可以是PSFCH、PSSCH或者PSCCH+PSSCH、PSSCH+PSFCH、PSCCH+PSFCH的组合等,此处不做具体限定。
上述通过确定不同的DRX状态或者节能状态,以便终端设备在节能的同时,保证侧链路的通信,避免冗余的重传以及降低资源选择时资源碰撞的概率。相较于现有技术在DRX的休眠期所有动态调度的信道都不接收,本方案在DRX状态下接收部分信道,可提高感知资源的准确度,同时避免不必要的重传。
下面具体介绍本申请实施例提供的配置非连续接收周期的实现方式。
终端设备发送数据时可以位于DRX激活期或者休眠期。当终端设备在发送数据时,根据资源池当前的配置可以得到在哪些具体的时频位置上接收物理侧行反馈信道PSFCH。当该时频位置不在终端设备的DRX激活期内时,终端设备将不会收到相应的反馈信息。为此,本申请实施例提供一种配置非连续接收周期的方法,可通过调整DRX状态或者激活期的窗口长度来达到可接收到相应反馈信息的目的。
参照图2所示,为本申请实施例提供的一种配置非连续接收周期的方法的流程示意图。 其包括:
201、若即将接收的物理侧行反馈信道位于第一终端的非连续接收周期的休眠期内,所述第一终端调整所述非连续接收周期,其中,所述物理侧行反馈信道承载第二终端响应于物理侧行共享信道的混合自动重传信息,所述物理侧行共享信道为所述第一终端向所述第二终端发送的侧行共享信道;
具体地,第一终端向第二终端发送物理侧行共享信道PSSCH;其中,第二终端响应于上述物理侧行共享信道,第二终端向第一终端发送混合自动重传信息HARQ。物理侧行反馈信道PSFCH承载有第二终端响应于物理侧行共享信道PSSCH的混合自动重传信息HARQ。
其中,当即将接收的(待接收的)物理侧行反馈信道PSFCH位于第一终端的非连续接收周期的休眠期内时,所述第一终端通过调整所述非连续接收周期,以便可接收所述物理侧行反馈信道PSFCH。
需要说明的是,本申请实施例中所述的调整所述非连续接收周期,可以是调整所述非连续接收周期的激活期,例如调整激活期的时长和/或起始位置,也可以是切换DRX状态等。本申请实施例对此不作具体限定。
作为第一种可选的实现方式,所述第一终端调整所述非连续接收周期,包括:
所述第一终端在不晚于所述物理侧行反馈信道的起始时刻触发第一计时器,其中,在所述第一计时器定时时间范围内,所述第一终端处于非连续接收周期的激活期内,所述第一计时器的定时时间范围不小于所述物理侧行反馈信道时域资源长度。
也就是说,在接收所述物理侧行反馈信道时,所述终端处于非连续接收周期的激活期内。其中,在激活期内所述终端可接收任意侧行信道,包括PSCCH,PSSCH,PSFCH以及物理侧行广播信道(physical sidelink broadcast channel,PSBCH)。其中,在不晚于所述物理侧行反馈信道的起始时刻,所述第一终端处于所述非连续接收周期的激活期内,以确保可以接收到所述物理侧行反馈信道。同时,所述第一终端处于所述非连续接收周期的激活期内的时长不少于所述物理侧行反馈信道时域资源长度,即不少于所述第一终端接收完所述物理侧行反馈信道,以确保完整接收物理侧行反馈信道。采用该手段,可以实现成功接收物理侧行反馈信道PSFCH。应理解,所述物理侧行反馈信道时域资源长度表示在时域上占用的连续或者不连续时域资源个数,包括但不限于OFDM符号个数,时隙个数,子帧个数,无线帧个数等。
具体地,如图3所示,终端设备可在不晚于PSFCH的起始时刻,开始进入激活期。为了完成接收PSFCH,因此还需要设定终端设备在激活期的时间长度。其中,在不晚于所述物理侧行反馈信道的起始时刻触发第一计时器Timer 1,Timer 1定时时间范围不小于所述物理侧行反馈信道的时域资源长度。其中,Timer 1可以由高层信令配置。
具体地,在所述第一终端触发所述第一计时器之前,所述第一终端可处于非连续接收周期的休眠期内。终端设备在不晚于PSFCH的起始时刻触发第一计时器Timer 1,并开始进入激活期。
可替代的,在所述第一终端触发所述第一计时器之前,所述第一终端可处于非连续接收周期的激活期内。其中,根据DRX的配置,如果在接收PSFCH时已经位于激活期外, 终端设备还可以直接扩展激活期的时长,如图4所示。其中,该扩展时长可由Timer1确定,具体数值可由高层参数配置。其中,通过扩展激活期,以便终端成功接收物理侧行反馈信道PSFCH。
具体地,在所述第一终端触发所述第一计时器之前,所述第一终端可处于非连续接收周期的激活期内。终端设备在不晚于PSFCH的起始时刻触发第一计时器Timer 1,并处于扩展后的激活期内。
作为第二种可选的实现方式,所述第一终端调整所述非连续接收周期,包括:
所述第一终端在不晚于所述物理侧行反馈信道的起始时刻触发第一计时器,其中,在所述第一计时器定时时间范围内所述第一终端可接收物理侧行反馈信道、物理侧行反馈信道和物理侧行控制信道、物理侧行反馈信道和物理侧行共享信道中的任一种。
本方案对上述各信道类型不做具体限定。其可以仅接收一种信道,也可以接收两种信道等。
也就是说,在接收所述物理侧行反馈信道时,所述终端处于可接收物理侧行反馈信道PSFCH(如表一中状态二)、物理侧行反馈信道和物理侧行控制信道PSFCH+PSCCH(如表一中状态四)、物理侧行反馈信道和物理侧行共享信道PSFCH+PSSCH中的任一种。
如图5所示,终端设备在不晚于PSFCH的起始时刻,如进入DRX状态二,此时在DRX状态二中,终端设备仅接收PSFCH,除此之外并不接收其他侧行信道。其中,为了完成接收PSFCH,因此还需要设定终端设备位于DRX状态二的时间长度。例如,在不晚于所述物理侧行反馈信道的起始时刻触发第一计时器Timer 1,Timer 1定时时间范围不小于所述第一终端接收完所述物理侧行反馈信道的时间长度。其中,Timer 1可以由高层信令配置。其中,如图5所示,在终端触发第一计时器之前,所述终端可处于非连续接收周期的休眠期内。Timer 1的时间和配置的激活期可以存在多种关系。如状态二的结束时刻可以与配置的激活期起始时刻有一定间隔,此时,设备可再次进入休眠期;或者,状态二的结束时刻可以与配置的激活期起始时刻恰好衔接,即DRX状态二的结束时刻恰好是DRX激活期的起始时刻;或者,在状态二的结束时刻可以与配置的激活期互相重叠,即状态二还未结束,设备已进入激活期等。本方案对此不做具体限定。
可替代的,如图6所示,终端设备可以在激活期结束后进入DRX状态二。也就是说,在激活期结束后,终端触发Timer1并进入状态二,其中终端处于状态二的时长可由Timer1确定,其中,Timer 1的具体数值可由高层参数配置。如,Timer 1的时间长度不低于所述物理侧行反馈信道时域资源长度,即不低于终端设备接收完PSFCH的时长。
需要说明的是,上述各种实现方式中的Timer1可以是相同的,也可以是不同的,此处不做具体限定。
进一步地,本方案的第一终端在调整所述非连续接收周期之前,可先确认所述非连续接收周期的激活期结束时刻与所述物理侧行反馈信道的起始时刻之间的间隔是否大于第一阈值。其中,若所述间隔不大于第一阈值,则可通过在激活期内进一步扩展激活期来实现接收;或者通过在激活期结束后进入DRX状态二来实现接收。具体可参阅图4、图6的描述,此处不再赘述。
其中,Timer1取值范围可以是1~32个正整数时隙等。可替代的,Timer 1的数值大小 还可以根据以下参数中的一个或多个进行确定,如(反馈)最小时间间隔T minigap:用于确定PSSCH和PSFCH之间最小的时间间隔;PSFCH周期:PSFCH反馈资源的周期;调整系数k:用于调整时间间隔的长短。
其中,根据最小时间间隔以及PSFCH反馈资源的周期,可确定至多经过T个时隙就会有反馈资源,则按照不同的最小时间间隔配比和PSFCH周期,可以确定时隙数量T的值,如表四所示:
表四
Figure PCTCN2020106668-appb-000001
也就是说,在时隙数量T对应的时间长度里面至少包含一个PSFCH的资源。其中,Timer1的时间长度可表示为:
L timer=k×T;
其中,K的取值可以为1~8之间的整数,具体可以由高层参数或者动态信令指示。
另一方面,Timer1的长度是PSFCH时域资源个数的整数倍,可以表示为:
L timer=k’×L PSFCH
其中,L PSFCH为时域资源个数,例如L PSFCH为2个PSFCH符号,例如k’为1~84中的正整数。其中,若所述第一终端通过确认所述非连续接收周期的激活期结束时刻与所述物理侧行反馈信道的起始时刻之间的间隔大于所述第一阈值,则可通过在休眠期内进入DRX状态来实现接收;或者通过结束休眠期进入激活期来实现接收。具体可参阅图3、图5的描述,此处不再赘述。
本申请实施例提供的配置非连续接收周期DRX cycle的方法,其中,非连续接收周期按照有高层信令或者动态信令指示出具体的配置,可以包括以下信息中的部分或者全部:激活期的时间或者占比,休眠期的时间或者占比,以及非连续接收周期的时间。
在数据发送后,若相应的反馈信道并不位于终端设备的激活期内,则终端设备可以在不晚于PSFCH的起始时刻,开始接收PSFCH。
需要说明的是,本申请中的起始时刻和结束时刻等只是示例性的描述,其还可以是起始符号或者结束符号,或者起始符号或者结束符号位于的时隙、子帧、系统帧等。
202、所述第一终端接收所述物理侧行反馈信道。
通过调整非连续接收周期,所述第一终端可实现接收所述物理侧行反馈信道。
通过本申请实施例,当待接收的物理侧行反馈信道位于终端的非连续接收周期的休眠期内时,终端通过调整非连续接收周期,进而实现成功接收物理侧行反馈信道。其中,通过切换DRX状态或者延长DRX激活时间,以确保可以接收PSFCH,避免因DRX休眠期造成的PSFCH漏检,避免非必要的重传,降低时延,可提高系统的可靠性。
如图7所示,本申请实施例还提供一种配置非连续接收周期的方法。第一终端可以通过反馈信息确定第二终端的非连续接收周期。其包括:
701、第一终端向第二终端发送物理侧行控制信道和物理侧行共享信道;
其中,上述第二终端可以是一个,也可以是多个,本方案对此不作具体限定。如第一终端采用单播,或者组播等方式发送物理侧行共享信道和物理侧行控制信道。
702、所述第一终端接收K个物理侧行反馈信道,所述物理侧行反馈信道承载第二终端响应于所述物理侧行共享信道的混合自动重传信息,K为大于1的整数;
例如工作在DRX状态二下,此时第一终端正常发送数据,第一终端可以接收PSFCH。
其中,上述第一终端接收K个物理侧行反馈信道,可以是在预设时长内,如可以是第一终端确定的统计时间长度,可在统计时间窗内统计是否接收到了发送数据的反馈信息,统计时间窗的长度可以通过以下方式获得:
1)由基站配置统计时间窗;
2)终端自行选择统计时间窗。
其中,统计时间窗长可以满足以下部分或者全部条件:
1)统计时间窗的长度是第一终端UE1的非连续接收周期的整数倍;
2)配置在资源池上;
3)根据业务类型或者业务的优先级信息由第一终端UE1选择长度。
703、所述第一终端根据所述K个物理侧行反馈信道的接收时间确定所述第二终端的激活时间;
其中,通过统计多个物理侧行反馈信道的接收时间,进而可确定第二终端的激活时间。
进一步地,上述步骤703,还可以包含统计第二终端反馈信息的状态,进而确定第二终端的DRX cycle。
该第二终端反馈信息的状态可包括第二终端未发送反馈信息,如在接收反馈信息时,第一终端未收到反馈信息,则可确定第一终端发送对应物理侧行共享信道时,第二终端可能处于休眠期。
进一步地,若第一终端周期发送的连续Y个物理侧行共享信道,第二终端均未反馈的HARQ信息,则可确定第一终端发送对应物理侧行共享信道时,第二终端处于休眠期,Y为大于等于1的正整数。进而可提高方案的可靠性,减少因漏检和虚警导致的判决不准确。
该第二终端反馈信息的状态还可包括第二终端发送反馈信息,如在接收反馈信息时,第一终端收到反馈信息,则可确定第一终端发送对应物理侧行共享信道时,第二终端处于激活期。
也就是说,统计时间窗中发送PSCCH/PSSCH后接收到相应的ACK/NACK,以及未收到反馈的DTX状态的位置,根据上述信息可确定第二终端UE2的DRX的激活时间以及非连续接收周期;
具体地,若未收到ACK/NACK(即DTX状态),则对应的PSCCH/PSSCH不位于DRX激活时间内;若收到ACK/NACK,则相应的PSCCH/PSSCH可能位于DRX激活时间内。
通过根据所有的ACK/NACK以及预留周期或者业务周期确定最小时隙集合,确定位于 激活时间内最长的连续的时隙集合,即为第二终端的非连续接收周期激活时间。
具体地,如图8所示,其中,UE1在统计时间窗内向UE2依次发送PSCCH/PSSCH1、PSCCH/PSSCH2、PSCCH/PSSCH3、PSCCH/PSSCH4、PSCCH/PSSCH5、PSCCH/PSSCH6、PSCCH/PSSCH7。
其中,UE1接收UE2的反馈,其接收到PSFCH3、PSFCH4、PSFCH5和PSFCH6,则对应的PSCCH/PSSCH位于UE2的DRX激活时间范围内;
对于非周期发送PSSCH收到相应HARQ反馈信息,如PSFCH3,则按照配置的预留周期或者业务周期对PSSCH进行平移,直到与其他周期发送的PSSCH时域资源重叠或者时域上连续,如图8所示,则该PSSCH平移后的时域资源也处于DRX激活时间。
UE1未接收到PSFCH 1、PSFCH2和PSFCH7(DTX状态),则对应的PSCCH/PSSCH不位于UE2的DRX激活时间内;
可选的,所述方法还包括步骤704,具体为704、所述第一终端根据所述第二终端的激活时间发送所述物理侧行控制信道和物理侧行共享信道。
其中,步骤704可以执行,也可以不执行,本申请对此不做具体限定。
其中,所述第一终端根据所述第二终端的激活时间发送所述物理侧行共享信道,包括:所述第一终端根据所述第二终端的激活时间调整所述第一终端的非连续接收周期,以便所述第一终端接收到所述第二终端发送的消息。
在确定DRX激活时间范围后,UE1可以调整自己的激活期或者切换DRX状态等,以便可以接收到所述UE2发送的消息。
其中,所述调整所述第一终端的非连续接收周期的具体实现手段,可以参照图2所示实施例的描述,在此不再赘述。其还可以是其他任意形式,本方案对此不作具体限定。
本申请实施例,第一终端可通过第二终端发送的反馈信息,来确定第二终端的激活时间,进而第一终端调整自身的非连续接收周期,以便可以接收到第二终端发送的消息。采用该手段,可避免因休眠期造成的PSFCH漏检,进而避免非必要的重传,降低时延,可提高系统的可靠性。
本申请实施例还提供一种配置非连续接收周期的方法。第一终端可向其他终端发送消息,以指示第一终端的非连续接收周期信息,其中该非连续接收周期信息包括DRX offset,period等。该方法包括:
第一终端向M个第二终端发送第一消息,所述第一消息携带所述第一终端的非连续接收周期信息,以便所述M个第二终端中的任一第二终端根据所述第一终端的非连续接收周期信息向所述第一终端发送第二消息。也就是说,所述非连续接收周期信息用于指示所述M个第二终端中的任一第二终端根据所述第一终端的非连续接收周期信息向所述第一终端发送第二消息,M为正整数。
作为第一种实现方式,第一终端可将非连续接收周期信息携带在主系统信息块(MasterInformationBlock,MIB)或者系统信息块(SystemInformationBlock,SIB)中,通过广播的方式发送出去;此时,M可以是1,也可以是大于1的整数。可选的,在发送上述信息时,第一终端可将非连续接收周期信息通过自己的source ID进行加扰,再进行发送。 例如,将编码后的信息的循环冗余校验(Cyclic Redundancy Check,CRC)通过source ID加扰。这样做的目的是为了只限于对第一终端感兴趣的UE才会检测这部分信息。
作为第二种实现方式,第一终端可将共用DRX信息common DRX cycle信息组播给组内的UE。第一终端可通过组播的方式发送上述信息。其中,common DRX cycle信息用于通知组内UE至少需要在common DRX激活期状态中保持激活以便接收信息。上述common DRX cycle信息可以承载在侧链路可控制信息SCI中,也可以承载在PSSCH中进行发送。
作为第三种实现方式,第一终端还可以在单播场景中发送非连续接收周期信息。第一终端可将非连续接收周期信息携带在PC5-RRC中。
其中,任一第二终端根据所述第一终端的非连续接收周期信息向所述第一终端发送第二消息,可以是任一第二终端通过调整自身的非连续接收周期来实现接收。
其中,在采用单播的方式和采用组播的方式时,UE1可以根据是否接收到了相应的反馈来判断UE2是否可以进行调整。
进一步地,第一终端在发送上述信息时,可以采用配置一定的重复次数以及发送的间隔gap。如图9所示,示例了重复3次进行发送,其中,gap如可以取0~7的整数。
与该实施例一致的,本申请实施例还提供一种配置非连续接收周期的方法。该方法包括:
第二终端接收第一终端发送的第一消息,所述第一消息携带所述第一终端的非连续接收周期信息;
所述第二终端根据所述第一终端的非连续接收周期信息向所述第一终端发送第二消息。
