Description

半静态调度资源配置方法、半静态调度方法及装置 技术领域
本申请涉及通信技术领域,尤其涉及一种半静态调度资源配置方法、半静态调度方法及装置。
背景技术
如图1所示,在新型无线电(new radio,NR)通信系统中,多播广播业务(multicast broadcast service,MBS)在(长期演进(long term evolution,LTE)中称为多媒体广播多播业务(multimedia broadcast multicast service,MBMS)),是面向多个用户设备(user equipment,UE)的业务,例如现场直播、定时播放节目等。MBS技术是指通过基站同时向多个UE发送MBS数据的技术。可以在基站与UE之间建立UE专用的承载以单播的形式发送MBS数据给UE,然而当大量UE需要接收某一MBS数据时,需要为大量的UE建立专用承载,会消耗大量的资源。也可以通过MBS专用的承载以广播的形式发送MBS数据给UE,这样只需要建立MBS专用的承载,所有对该MBS业务感兴趣的UE都可以接收到该MBS数据。
基站的下行调度方式可以分为动态调度和半静态调度(semi-persistent scheduling,SPS)。基站动态调度进行下行传输,每次都需要发送下行控制信息(downlink control information,DCI)给UE。对于频繁的下行数据传输以及用户数量庞大的情况下,所需控制信息的开销很大。使用SPS进行下行传输的特点为:一次授权(grant),周期性使用,可以有效地节省基站用于调度指示的DCI占用的资源。也就是说,基站通过一次DCI调度,即可为UE激活一系列周期性的下行资源,下行资源用于传输下行数据,从而UE可以在相应的资源接收下行数据,而无需基站每次进行下行传输都需要使用一个DCI通知UE相应的资源位置。
然而,目前SPS的资源配置仅针对单播业务,对于MBS业务如何进行SPS的资源配置,目前尚未能够实现以较低的信令开销实现对MBS业务的SPS的资源配置。
发明内容

需要说明的是,本申请下述实施例中各个网元之间的消息名字或消息中各参数的名字等只是一个示例,具体实现中也可以是其他的名字,本申请实施例对此不做具体限定。
下面将结合图1至图8对本申请实施例提供的半静态调度资源配置方法进行具体阐述。
如图3所示,为本申请实施例提供的一种半静态调度资源配置方法的流程示意图。网络设备100对第一组终端设备201进行半静态调度资源配置,该第一组终端设备201包括X1~Xn个终端设备200。示例性地,该方法可以包括:
S101、网络设备向第一组终端设备发送第一信息,该第一信息用于指示频域资源的周期(periodicity)P和第一起始时刻O1。相应地,第一组终端设备201中的任一个终端设备接收该第一信息。
本实施例中,网络设备通过SPS调度第一组终端设备,给第一组终端发送MBS数据。因此,网络设备需要首先给该第一组终端设备配置SPS资源。对于某一个MBS业务,如果网络设备配置了SPS资源,则对于此MBS业务感兴趣的或正在接收此MBS业务的终端设备均可以通过此SPS资源接收MBS数据。其中,MBS业务可以是广播(broadcast)业务,也可以是组播/多播(multicast)业务。
网络设备通过第一信息给第一组终端设备配置统一的SPS频域资源和SPS频域资源的起始时刻。可选的,该起始时刻可以是第一信息指示的激活该第一组终端设备的SPS频域资源的时刻,该起始时刻也可以是根据第一信息指示的参考时刻计算出的激活该第一终端设备的SPS频域资源的时刻。该第一组终端设备包括X1~Xn个终端设备。该第一信息可以是有多种实现,下面分别进行描述:
实现方式A,该第一信息包括无线资源控制(radio resource control,RRC)信息和下行控制信息(downlink control information,DCI)。该RRC信息包括SPS频域资源的周期P。RRC信息配置的一组周期性的SPS资源如图4所示。
此外,该RRC信息还可以包括配置的用于SPS下行的混合自动重传请求(hybrid automatic repeat request,HARQ)进程号(number of configured HARQ processes for SPS DL),以及用于下行SPS的物理上行控制信道(physical uplink control channel,PUCCH)的HARQ资源(HARQ resource for PUCCH for DL SPS)等。在另外的实现中,该RRC信息也可以替换为系统信息块(system information block,SIB),或者MBS控制/配置信息(MBS控制/配置信息的逻辑信道(比如多媒体广播多播业务控制信道(MBMS control channel,MCCH)传输),单小区多媒体广播多播业务控制信道(single cell-MBMS control channel,SC-MCCH))发送的信息等,媒体接入控制控制单元(media access control control element,MAC CE)等,不做限制。
当网络设备要为该第一组终端设备中的某个或某些或全部终端设备激活SPS资源时,向该终端设备或这些终端设备分别发送DCI,该DCI包括SPS频域资源的第一起始时刻O1(即第一个激活的SPS资源的时域位置)。该第一起始时刻O1可以包括起始的系统帧号 SFN start time、起始时刻的时隙slot start time、起始时刻的符号symbol start time,本申请不做限制。
由于RRC信息配置的SPS资源用于为第一组终端设备调度MBS数据,对于首次激活SPS资源的DCI,该组终端设备均可以采用基于组的无线网络临时标识(group-based radio network temporary identifier)加扰该DCI,即基于组的无线网络临时标识用于对激活第一组终端设备的DCI进行加扰。可选的,基于组的无线网络临时标识可以是用于MBS动态调度的无线网络临时标识(radio network temporary identifier,RNTI),比如组无线网络临时标识(group radio network temporary identifier,G-RNTI),也可以仅用于半静态调度的RNTI,不做限制。以下以基于组的无线网络临时标识是G-RNTI为例进行说明。从而,该第一组终端设备中的每个终端设备均监听此G-RNTI加扰的DCI,进行SPS资源的激活。
对于首次激活SPS资源的DCI,也可以采用终端设备专用的(UE specific)RNTI加扰该DCI。可选的,终端设备专用的RNTI例如可以是仅用于半静态调度的RNTI,比如配置的调度无线网络临时标识(configured scheduling RNTI,CS-RNTI),半静态调度无线网络临时标识(semi-persistent scheduling RNTI,SPS-RNTI),还可以是也用于动态调度的RNTI,比如小区无线网络临时标识(cell RNTI,C-RNTI)从而,该第一组终端设备中的每个终端设备均监听该终端设备专用的RNTI加扰的DCI,进行SPS资源的激活。可以理解的是,该终端设备级别的RNTI可以用此终端设备其他业务的动态调度,也可以仅用于该MBS业务的SPS调度。
实现方式B,该第一信息为RRC信息。该RRC信息包括以下至少一个信息:频域资源的周期P,参考时间。其中,该参考时间可以是网络设备配置的首个SPS资源的时间。可选的,参考时间可以包括系统帧号(system frame number,SFN)、时隙(slot)号、符号(symbol)号、偏置(offset),本申请不做限制。根据该参考时间和频域资源的周期P可以确定一系列的SPS资源。此外,该RRC信息还可以包括配置的用于SPS下行的HARQ进程号,以及用于下行SPS的PUCCH的HARQ资源等。
实现方式C,该第一信息为MAC CE。该MAC CE承载在物理下行共享信道(physical downlink shared channel,PDSCH)上,MAC CE本身需要在PDCCH上传输的DCI进行调度。在本实现方式C中,通过MAC CE配置SPS资源,以及激活或去激活SPS资源的使用。具体地,该MAC CE包括以下至少一个信息:频域资源的周期P,参考时间。其中,该参考时间可以是网络设备配置的首个SPS资源的时间。可选的,参考时间可以包括系统帧号SFN、时隙(slot)号、符号(symbol)号,不做限制。根据该参考时间和频域资源的周期P可以确定一系列的SPS资源。此外,该MAC CE还可以包括配置的用于SPS下行的HARQ进程号,以及用于下行SPS的PUCCH的HARQ资源等。
由于MAC CE配置的SPS资源用于为第一组终端设备调度MBS数据,对于首次激活SPS资源的MAC CE,该组终端设备均可以采用基于组的RNTI加扰的DCI调度该MAC CE。可选的,基于组的无线网络临时标识可以是用于MBS动态调度的RNTI,比如G-RNTI,也可以仅用于半静态调度的RNTI,不做限制。以下以基于组的无线网络临时标识是G-RNTI为例进行说明。从而,该第一组终端设备中的每个终端设备均监听此G-RNTI加扰的DCI,接收MAC CE,获取SPS资源的配置,并激活或者开始使用SPS资源接收MBS业务数据。可以理解的是,该G-RNTI也可以同时用于该MBS业务的动态调度,也可以仅用于该MBS 业务的SPS调度。
也可以采用终端设备专用的RNTI加扰该DCI调度。可选的,终端设备专用的RNTI例如可以是仅用于半静态调度的RNTI,比如CS-RNTI,SPS-RNTI。还可以是用于动态调度的RNTI,比如C-RNTI。从而,该第一组终端设备中的每个终端设备均监听该终端设备专用的RNTI加扰的DCI,接收MAC CE,获取SPS资源的配置,并激活或开始使用SPS资源接收MBS业务数据。可以理解的是,该终端设备专用的RNTI可以用此终端设备其他业务的动态调度,也可以仅用于该MBS业务的SPS调度。
实现方式D,该第一信息为SIB和/或MBS控制/配置信息(MBS控制/配置信息的逻辑信道(比如MCCH,SC-MCCH)发送的信息等。其中,该SIB可以是与MBS相关的SIB,例如用于承载MBS业务配置/控制信息的SIB。该第一信息包括以下至少一个信息:频域资源的周期P,参考时间。其中,参考时间的概念与上面的描述相同。此外,该第一信息还可以包括配置的用于SPS下行的HARQ进程号,以及用于下行SPS的PUCCH的HARQ资源等。
举例说明,上述配置的SPS资源均用于数据的新传。如果终端设备没能成功解码数据包,则会向网络设备发送失败响应(non-acknowledgement,NACK),网络设备会为此终端设备调度此数据包的重传。重传采用动态调度方式,但在SPS激活的情况下,调度数据包的重传的DCI仍采用CS-RNTI/SPS-RNTI加扰。终端设备对新收到的数据包进行解码,如果解码成功,向网络发送成功响应(acknowledgement,ACK);如果不成功仍返回NACK,网络设备继续为终端设备调度此数据包的重传,直至终端设备返回ACK,或者计时器超时,或者网络设备在同一个HARQ进程上为此终端设备调度其他数据包的新传,或者下一个使用同一个HARQ进程的SPS资源到来等。
S102、在第一时刻T1上,使用所述频域资源向所述一组终端设备发送第一MBS的数据,所述第一时刻T1满足T1=O1+NP,N为正整数。相应地,第一组终端设备201中的任一个终端设备接收该第一MBS的数据。
第一组终端设备的每个终端设备接收上述第一信息,从而该组终端设备中的每个终端设备可以确定出相同的第一时刻T1,在第一时刻T1均监听网络设备发送的MBS数据。
对于上述实现方式A,终端设备接收并成功解码用于激活SPS资源的DCI后,确定此DCI是用于激活SPS资源或者说用于激活某一个SPS资源(假设网络设备为该终端设备配置了多套SPS资源)。则网络设备在第一时刻T1上,使用频域资源向一组终端设备发送MBS数据,该第一时刻T1满足O1+NP,N为正整数,终端设备在第一时刻T1的频域资源上接收该MBS数据。其中O1与P的粒度可以相同,可选的均为系统帧级别,或者时隙级别,或者符号级别,或者可以不同,比如O1为一个系统帧内的一个时隙,P的单位为系统帧(即P个系统帧),本申请不做限制。具体地,该DCI可以包括起始时刻的系统帧号SFN start time,和/或起始时刻的时隙slot start time,和/或起始时刻的符号symbol start time。则O1为通过SFN start time和/或起始时刻的时隙slot start time,和/或起始时刻的符号symbol start time确定的时刻。可选的,SPS频域资源的周期P换算为与确定O1的参数中粒度最小的参数一致。比如O1通过SFN start time和起始时刻的时隙slot start time确定,如果频域资源的周期的配置大于slot粒度,则频域资源的周期可以换算成slot级别。频域资源的周期配置为SFN粒度,则
P=numberOfSlotsPerFrame*频域资源的周期。
其中,numberOfSlotsPerFrame为每帧中的时隙数量。
以下以DCI包括起始时刻的系统帧号SFN start time和起始时刻的时隙slot start time为例进行说明,SPS频域资源的周期P为下式中的periodicity:根据公式1计算出第N个频域资源的SFN以及SFN中的时隙(slot number in the frame)如下:
(numberOfSlotsPerFrame×SFN+slot number in the frame)=[(numberOfSlotsPerFrame×SFN start time+slot start time)+N×periodicity×numberOfSlotsPerFrame/10]modulo(1024×numberOfSlotsPerFrame)
                      …公式1
则终端设备在计算出的每个频域资源的SFN和时隙号(slot number in the frame)接收MBS数据。对于上述实现方式B,RRC信息包括以下至少一个信息:频域资源的周期P,参考时间。该参考时间可以是网络设备配置的首个SPS资源的时间,也可以是其它时间。可选的,参考时间可以包括系统帧号SFN、时隙(slot)号、符号(symbol)号,偏置(offset),不做限制。则终端设备接收到该RRC消息后,可以根据该参考时间和频域资源的周期P可以确定一系列的SPS资源。终端设备可以从第一个可用的频域资源(可选的,第一起始时刻O1)开始接收MBS数据。可以理解的,第一个可用的频域资源为多个频域资源的某一个,可以是终端设备确定频域资源的时刻后第一个可用的频域资源。
以下以参考时间的配置为SFN和slot为例进行说明,或者说通过配置的SFN和slot确定参考时间。一种可能的方式,可以根据公式2计算出第N个频域资源的SFN以及SFN中的时隙(slot number in the frame)如下:
(numberOfSlotsPerFrame×SFN+slot number in the frame)=[(numberOfSlotsPerFrame×SFN+offset+slot)+N×periodicity×numberOfSlotsPerFrame/10]modulo(1024×numberOfSlotsPerFrame)
                 …公式2
其中,slot number in the frame即为上述slot,numberOfSlotsPerFrame为每帧中的时隙数。这里,通过numberOfSlotsPerFrame×SFN+offset+slot确定参考时间。例如,该参考时间为首个SPS频域资源的时间,则根据公式2可以确定一系列SPS频域资源的时域位置。
其中,上述offset可以为SFN或slot粒度,也可以是symbol粒度,其值可以配置为0。可选的,offset也可以缺省。
则终端设备使用接收到RRC信息的内容确定每个频域资源的时刻,并可以某一个可用的频域资源(例如,第一个可用的频域资源)开始接收MBS数据。
对于上述实现方式C,MAC CE包括以下至少一个信息:频域资源的周期P,参考时间,参考时间的含义可参考上面的描述,则终端设备接收到该MAC CE后,可以根据该参考时间和频域资源的周期P可以确定一系列的SPS资源。终端设备可以从第一个可用的频域资源(可选的,第一起始时刻O1)开始接收MBS数据。可以理解的第一个可用的频域资源为多个频域资源的某一个,可以是终端设备确定频域资源的时刻后第一个可用的频域资源。终端设备可以使用接收到MAC CE的内容确定每个频域资源的时刻,并可以从第一 个可用的频域资源接收MBS数据。
对于上述实现方式D,广播信息包括以下至少一个信息:频域资源的周期P,参考时间,参考时间的含义可参考上面的描述,则终端设备接收到该广播信息后,可以根据该参考时间和频域资源的周期P可以确定一系列的SPS资源。终端设备可以从第一个可用的频域资源(可选的,第一起始时刻O1)开始接收MBS数据。可以理解的第一个可用的频域资源为多个频域资源的某一个,可以是终端设备确定频域资源的时刻后第一个可用的频域资源。终端设备可以使用接收到广播信息的内容确定每个频域资源的时刻,并可以从第一个可用的频域资源接收MBS数据。
根据本申请实施例提供的一种半静态调度资源配置方法,网络设备针对一组终端设备统一进行半静态调度资源配置,可以以较低的信令开销实现对MBS业务的SPS的资源配置。
对于单播业务的SPS配置,其配置的SPS资源如图4所示,可以是一组周期性的SPS资源。
网络设备通过发送DCI激活该单播业务的SPS资源,DCI中包括SPS的频域资源、以及时域资源的起始时刻的系统帧号SFN start time和起始时刻的时隙slot start time。从而,UE可以根据上述SPS资源的周期以及SFN start time、slot start time通过公式1计算出第N个SPS的时域资源SFN以及SFN中的时隙(slot number in the frame)。
如果UE成功激活SPS资源,也就是UE收到并成功解码由CS-RNTI(在NR中使用)/SPS-RNTI(在LTE中使用)加扰的激活SPS的DCI(承载在物理下行控制信道(physical downlink control channel,PDCCH)上),则开始使用通过上述公式1计算得出的周期性SPS资源接收数据。如果UE成功接收SPS传输的数据,则向网络设备发送成功响应(acknowledgement,ACK);如果UE没能成功解码SPS资源上传输的数据,则向网络设备发送失败响应(non-acknowledgement,NACK)。网络通过ACK/NACK可以判断出该UE是否已经激活了SPS资源。如果网络没有收到此UE的ACK/NACK,也就意味着此UE没有使用SPS资源接收数据,则会给此UE重新发送DCI,用于激活SPS资源。如图5所示,当网络设备对此UE重新发送DCI时,DCI中所指示的SFN start time,slot start time由网络设备确定,重新激活的SPS的时域资源可以与首次未成功激活的SPS的时域资源不一致。
采用上述网络设备给接收同一MBS业务的一组终端设备进行统一配置SPS资源的方案,然而,如果一个终端设备中有一个或一些UE错过或没有成功解码激活SPS资源的DCI,则会错过一些SPS资源上传输的数据,造成丢包,降低这些UE的服务质量;如果该组终端设备所属的小区已经开始在SPS资源上进行MBS数据的调度,如果有UE通过切换流程切换到这个小区,或者该小区中对此MBS业务开始感兴趣的UE想要接收MBS数据,这些UE统称为新入UE,如果这些UE不知道此小区的SPS资源的配置和激活情况,则会无法接收通过SPS调度的MBS数据。因此,网络设备在给一组终端设备统一配置SPS资源,如何同时考虑上述未被激活的UE或新入UE?
如图6所示,为本申请实施例提供的又一种半静态调度资源配置方法的流程示意图,网络设备100对第一组终端设备201和第二组终端设备202进行半静态调度资源配置,该第一组终端设备201包括X1~Xn个终端设备,为网络设备第一次发送激活命令便被激活的 一些终端设备。该第二组终端设备202包括Y1~Ym个终端设备,为上述由于未接收到网络设备第一次发送的激活命令而未被激活的终端设备,和/或新入终端设备。网络设备100还可以对第三组终端设备203去激活频域资源,该第三组终端设备203可以是上述第一组终端设备201和第二组终端设备202,也可以包括更多被激活的UE。示例性地,该方法可以包括:
S201、网络设备向第一组终端设备发送第一信息,所述第一信息用于指示频域资源的周期P和第一起始时刻O1。相应地,第一组终端设备402中的任一个终端设备接收该第一信息。
该步骤的具体实现可参考图3所示实施例的步骤S101。
S202、在第一时刻T1上,使用所述频域资源向所述一组终端设备发送第一多播广播业务MBS的数据,所述第一时刻T1满足O1+NP,N为正整数。相应地,第一组终端设备402中的任一个终端设备接收该第一MBS的数据。
该步骤的具体实现可参考图3所示实施例的步骤S102。
S203、网络设备向第二组终端设备发送第二信息,所述第二信息用于指示频域资源的第二起始时刻O2,O2与O1满足O2=O1+MP,M为大于或等于0的整数。相应地,第二组终端设备中的任一个终端设备接收该第二信息。
针对由于未接收到网络设备发送的第一次激活命令而未被激活的和/或新入的一个或一组终端设备,网络设备可以重新发送第二信息。该第二信息所指示的内容与第一信息类似,其用于指示频域资源的第二起始时刻O2,O2与O1满足O2=O1+MP,M为大于或等于0的整数。即网络设备指示该第二组终端设备在O1之后的M个SPS资源上监听MBS数据。重新激活的SPS资源与已经被激活的SPS资源在时序上对齐。
与第一信息相似,第二信息也可以有多种实现:
实现方式E,若第一信息包括RRC信息和DCI,其中,RRC信息包括频域资源的周期P。第二组终端设备可能接收到了该RRC信息,但未接收到激活该频域资源的DCI,第二组终端设备未被激活SPS资源。网络设备向该第二组终端设备发送第二信息,该第二信息可以是DCI。该DCI包括SPS频域资源的第二起始时刻O2。如图7所示,第一组终端设备被激活的第一起始时刻O1包括起始时刻的系统帧号SFN start time1、起始时刻的时隙slot start  tim1e、起始时刻的符号symbol start time,不做限制;第二组终端设备的第1~3个SPS资源未被激活,第二组终端设备未在这3个SPS资源上接收MBS数据,第二组终端设备在第二起始时刻O2被激活,该第二起始时刻O2可以包括起始时刻的系统帧号SFN start tim2、起始时刻的时隙slot start time2、起始时刻的符号symbol start time2,不做限制;进一步地,还可能存在部分终端设备在起始时刻O2也未被激活或新加入,例如,该部分终端设备的第1~6个SPS资源未被激活,该部分终端设备未在这6个SPS资源上接收MBS数据,则该部分终端设备可以在第三起始时刻O3被激活,该起始时刻O3可以包括起始时刻的系统帧号SFN start  tim3、起始时刻的时隙slot start time3、起始时刻的符号symbol start time3,不做限制。起始时刻O3仍包含于所述DCI中。可以看出,多次激活发送的DCI均指向原SPS资源图样中的资源位置,即重新激活的SPS资源与已经激活的SPS资源在时序上对齐。不然,在重新激活第二组终端设备时,可能造成第二组终端设备与第一组终端设备对于SPS资源的时域位置的理 解不同。
由于是重新激活一组终端设备调度同一个MBS数据,对于重新激活SPS资源的DCI,该组终端设备均可以采用基于组的G-RNTI加扰该DCI,即基于组的无线网络临时标识用于对重新激活第二组终端设备的DCI进行加扰。可选的,基于组的无线网络临时标识可以是用于MBS动态调度的RNTI,比如G-RNTI,也可以仅用于半静态调度的RNTI,不做限制。以下以基于组的无线网络临时标识是G-RNTI为例进行说明。从而,该第二组终端设备中的每个终端设备均监听此G-RNTI加扰的DCI,进行SPS资源的激活。可以理解的是,该G-RNTI也可以同时用于该MBS业务的动态调度,也可以仅用于该MBS业务的SPS调度。
由于网络设备知道接收MBS数据的终端设备中哪些终端设备没有被成功激活,或哪些终端设备是新入终端设备,则对于重新激活SPS资源的DCI,也可以采用终端设备专用的RNTI加扰该DCI。终端设备专用的RNTI例如可以是仅用于半静态调度的RNTI,比如CS-RNTI,SPS-RNTI,还可以是也用于动态调度的RNTI,比如C-RNTI。从而,该第二组终端设备中的每个终端设备均监听该终端设备专用的RNTI加扰的DCI,进行SPS资源的激活。可以理解的是,该终端设备专用的RNTI可以用此终端设备其他业务的动态调度,也可以仅用于该MBS业务的SPS调度。
实现方式F,该第二信息为RRC信息。该RRC信息包括以下至少一个信息:频域资源的周期P,参考时间。其中,该参考时间可以是网络设备配置的首个SPS资源的时间。可选的,参考时间可以包括系统帧号SFN、时隙(slot)号、符号(symbol)号,不做限制。根据该参考时间和频域资源的周期P可以确定一系列的SPS资源。此外,该RRC信息还可以包括配置的用于SPS下行的HARQ进程号,以及用于下行SPS的PUCCH的HARQ资源等。
实现方式G,该第二信息为MAC CE。该MAC CE承载在PDSCH上,MAC CE本身需要在PDCCH上传输的DCI进行调度。在本实现中,通过MAC CE配置SPS资源,以及重新激活SPS资源的使用。具体地,该MAC CE包括以下至少一个信息:频域资源的周期P,参考时间。其中,该参考时间可以是网络设备配置的首个SPS资源的时间。可选的,参考时间可以包括系统帧号SFN、时隙(slot)号、符号(symbol)号,不做限制。根据该参考时间和频域资源的周期P可以确定一系列的SPS资源。此外,该第二信息还可以包括配置的用于SPS下行的HARQ进程号,用于下行SPS的PUCCH的HARQ资源,以及第二组终端设备在第二时刻T2之前的SPS资源上未接收到的数据包等。如图8所示,UE2未被调度SPS1的MAC CE激活,从而未接收到SPS1;UE2被调度SPS2的MAC CE激活,从而可以接收到SPS2及其后的其它SPS资源上的数据包,其中,调度SPS2的MAC CE可以包括SPS1上的数据包。同理,UE3未被调度SPS1和SPS2的MAC CE激活,从而未接收到SPS1和SPS2;UE3被调度SPS3的MAC CE激活,从而可以接收到SPS3及其后的其它SPS资源上的数据包,其中,调度SPS3的MAC CE可以包括SPS1和SPS2上的数据包。
由于MAC CE配置的SPS资源用于为第二组终端设备调度MBS数据,对于重新激活SPS资源的MAC CE,该组终端设备均可以采用基于组的RNTI加扰的DCI调度该MAC CE。 可选的,基于组的无线网络临时标识可以是用于MBS动态调度的RNTI,比如G-RNTI,也可以仅用于半静态调度的RNTI,不做限制。以下以基于组的无线网络临时标识是G-RNTI为例进行说明。从而,该第二组终端设备中的每个终端设备均监听此G-RNTI加扰的DCI,接收MAC CE,获取SPS资源的配置,并激活或者开始使用SPS资源。可以理解的是,该G-RNTI也可以同时用于该MBS业务的动态调度,也可以仅用于该MBS业务的SPS调度。再次或多次激活发送的MAC CE均指向原SPS资源图样中的资源位置,即重新激活的SPS资源与已经激活的SPS资源在时序上对齐。
也可以采用终端设备专用的RNTI加扰的该DCI。可选的,终端设备专用的RNTI例如可以仅用于半静态调度的RNTI,比如CS-RNTI,SPS-RNTI。还可以是用于动态调度的RNTI,比如C-RNTI。从而,该第二组终端设备中的每个终端设备均监听该终端设备专用的RNTI加扰的DCI,接收MAC CE,获取SPS资源的配置,并激活或开始使用SPS资源接收MBS业务数据。可以理解的是,该终端设备专用的RNTI可以用此终端设备其他业务的动态调度,也可以仅用于该MBS业务的SPS调度。
实现方式H,该第二信息为SIB和/或MBS控制/配置信息(MBS控制/配置信息的逻辑信道(比如MCCH,SC-MCCH)发送的信息等。其中,该SIB可以是与MBS相关的SIB,例如用于承载MBS业务配置/控制信息的SIB。该第二信息包括以下至少一个信息:频域资源的周期P,参考时间。其中,参考时间的概念与上面的描述相同。此外,该第二信息还可以包括配置的用于SPS下行的HARQ进程号,以及用于下行SPS的PUCCH的HARQ资源等。
S204、网络设备在第二时刻T2上,使用频域资源向第二组终端设备发送第一MBS的数据,第二时刻T2满足O2+KP,K为正整数。相应地,第二组终端设备中的任一个终端设备接收该第一MBS的数据。
第二组终端设备的每个终端设备接收到上述第二信息,网络设备给每个终端设备配置的第二起始时刻O2相同,从而该组终端设备中的每个终端设备可以确定出相同的第二时刻T2,在第二时刻T2均监听网络设备发送的MBS数据。且第二时刻T2上的频域资源与第一时刻T1上的频域资源对齐,从而网络设备可以在同一组周期性的SPS资源上向多个终端设备(第一组终端设备和第二组终端设备)发送同一MBS数据。
对于上述实现方式E,第二组终端设备中的每个终端设备接收并成功解码用于激活SPS资源的DCI后,确定此DCI是用于重新激活某一个SPS资源的(假设网络设备为该终端设备配置了多套SPS资源,该DCI还可以包括SPS资源组的索引(index))。则网络设备在第二时刻T2上,使用频域资源向第二组终端设备发送MBS数据,该第二时刻T2满足O2+KP,K为正整数,第二组终端设备在第二时刻T2的频域资源上接收该MBS数据。具体地,该DCI包括起始时刻O2的系统帧号SFN start time,和/或起始时刻的时隙slot start time,和/或起始时刻的符号symbol start time,可以根据公式1计算出第K个频域资源的SFN、和/或SFN中的时隙(slot number in the frame)、和/或时隙中的符号。
网络设备给第二组终端设备发送G-RNTI加扰的重新激活命令时,第一组终端设备也可以采用同一个G-RNTI监听到该重新激活命令,且监听到该重新激活命令是用于激活同一组SPS资源的(重新激活命令包括SPS资源组的索引),由于第一组终端设备已在第一 起始时刻O1被激活,则可以处理该重新激活命令。也可以在收到该重新激活命令后,基于该重新激活命令所指示的起始时刻O2的系统帧号SFN start time和/或起始时刻的时隙slot start  time,和/或起始时刻的符号symbol start time,根据公式1重新计算一系列的在SPS资源上接收MBS数据的时刻。重新计算出的起始时刻的频域资源与第一时刻T1上的频域资源对齐。则终端设备在计算出的每个频域资源的SFN、和/或SFN中的时隙、和/或每个时隙中的符号接收MBS数据。
对于上述实现方式F,RRC信息包括以下至少一个信息:频域资源的周期P,参考时间。该参考时间可以是网络设备配置的首个SPS资源的时间,也可以是其它时间。可选的,参考时间可以包括系统帧号SFN、时隙(slot)号、符号(symbol)号,不做限制。则终端设备接收到该RRC消息后,可以根据该参考时间和频域资源的周期P可以确定一系列的SPS资源。终端设备可以从接收到RRC信息后的下一个可用的频域资源(第二起始时刻O2)开始接收MBS数据(终端设备错过了接收到RRC信息前的若干个频域资源上的数据)。可以理解的,下一个可用的频域资源为多个频域资源的某一个,可以是终端设备接收到RRC信息的时刻后第一个可用的频域资源。
以下以参考时间的配置为SFN和slot为例进行说明,或者说通过配置的SFN和slot确定参考时间。一种可能的方式,可以根据公式2计算出第N个频域资源的SFN以及SFN中的时隙(slot number in the frame)。则终端设备使用接收到的RRC信息的内容确定每个频域资源的时刻,可以从某一个可用的频域资源开始接收MBS数据。对于上述实现方式G,MAC CE包括以下至少一个信息:频域资源的周期P,参考时间。该参考时间可以是网络设备配置的首个SPS资源的时间,也可以是其它时间。可选的,参考时间可以包括系统帧号SFN、时隙(slot)号、符号(symbol)号,不做限制。则终端设备接收到该MAC CE后,可以根据该参考时间和频域资源的周期P可以确定一系列的SPS资源。终端设备可以从接收到MAC CE后的下一个可用的频域资源(第二起始时刻O2)开始接收MBS数据(终端设备错过了接收到MAC CE前的若干个频域资源上的数据,错过接收的数据可以包括在MAC CE中)。可以理解的,下一个可用的频域资源为多个频域资源的某一个,可以是终端设备接收到MAC CE的时刻后第一个可用的频域资源。
以下以参考时间的配置为SFN和slot为例进行说明,或者说通过配置的SFN和slot确定参考时间。一种可能的方式,可以根据公式2计算出第N个频域资源的SFN以及SFN中的时隙(slot number in the frame)。则终端设备使用接收到的MAC CE的内容确定每个频域资源的时刻,可以从某一个可用的频域资源开始接收MBS数据。
对于上述实现方式H,广播信息包括以下至少一个信息:频域资源的周期P,参考时间。该参考时间可以是网络设备配置的首个SPS资源的时间,也可以是其它时间。可选的,参考时间可以包括系统帧号SFN、时隙(slot)号、符号(symbol)号,不做限制。则终端设备接收到该广播信息后,可以根据该参考时间和频域资源的周期P可以确定一系列的SPS资源。终端设备可以从接收到广播信息后的下一个可用的频域资源(第二起始时刻O2)开始接收MBS数据(终端设备错过了接收到广播信息前的若干个频域资源上的数据)。可以理解的,下一个可用的频域资源为多个频域资源的某一个,可以是终端设备接收到广播信息的时刻后第一个可用的频域资源。
以下以参考时间的配置为SFN和slot为例进行说明,或者说通过配置的SFN和slot确定参考时间。一种可能的方式,可以根据公式2计算出第N个频域资源的SFN以及SFN中的时隙(slot number in the frame)。则终端设备使用接收到的广播信息的内容确定每个频域资源的时刻,可以从某一个可用的频域资源开始接收MBS数据。
S205、网络设备向第三组终端设备发送第三信息,所述第三信息用于去激活所述频域资源。相应地,第三组终端设备中的任一个终端设备接收该第三信息。
当网络设备想要去激活/释放此MBS业务的SPS资源时,比如在业务结束,一段时间没有此MBS业务的数据,核心网将此MBS业务的协议数据单元(protocol data unit,PDU)/MBS会话释放等情况下,网络设备可以向使用此SPS资源接收此MBS业务的第三组终端设备发送第三信息,该第三信息用于指示去激活/释放此MBS业务的SPS资源,可以称为去激活命令。
该第三信息可以是上述DCI,RRC信息,MAC CE和广播信息等。该第三信息的加扰方式与上文相同,可使用G-RNTI或终端设备级别的RNTI。
S206、第三组终端设备中的任一个终端设备向网络设备发送反馈信息。相应地,网络设备接收第三组终端设备中的至少一个终端设备的反馈信息。
如果第三组终端设备中的任一个终端设备成功接收并解码该第三信息,则向网络设备发送反馈信息,该反馈信息用于指示接收到第三信息。
S207、网络设备未接收到所述第三组终端设备中的所有终端设备的反馈信息,向所述第三组终端设备发送第四信息,直至接收到所述第三组终端设备中的所有终端设备的反馈信息,所述第四信息用于去激活所述频域资源。
如果第三组终端设备中存在任一个终端设备没有收到或成功解码第三信息,则不会向网络设备反馈,网络设备即可确定这个或这些终端设备的情况。如果此时这些终端设备继续按照SPS资源的配置去接收MBS数据,将会造成终端设备耗电。网络设备需要为这些终端设备重新发送发送第四信息,该第四信息用于指示去激活或释放此MBS业务的SPS资源。该第四信息也可以使用组RNTI或终端设备级别的RNTI加扰。该第四信息可以是上述DCI,RRC信息,MAC CE和广播信息等。
举例说明,网络设备再次/多次发送G-RNTI加扰的去激活命令去激活或释放此SPS资源,也就是说这组终端设备均监听此G-RNTI加扰的DCI,进行SPS资源的去激活。可选的,对于已经去激活/释放此SPS资源的终端设备,可以通过去激活命令中的相应指示信息,比如SPS index等,不处理去激活命令,不再向网络设备进行去激活反馈。
举例说明,由于网络设备知道哪些终端设备没有成功去激活或释放此SPS资源,则网络设备可以使用终端设备级别的RNTI加扰去激活命令,对于没有去激活SPS资源的这些终端设备进行取激活。
网络设备发送第四信息,直至接收到第三组终端设备中的所有终端设备的反馈信息,即表明第三组终端设备中的所有终端设备均接收到了去激活命令。
S208、网络设备释放所述频域资源。
第三组终端设备中的所有终端设备均接收到了去激活命令后,网络设备可以释放该SPS资源,以提高SPS资源的利用率。
根据本申请实施例提供的一种半静态调度资源配置方法,网络设备针对一组终端设备统一进行半静态调度资源配置,可以以较低的信令开销实现对MBS业务的SPS的资源配置;如果存在未被激活的终端设备或新入终端设备,网络设置统一激活这些终端设备的半静态调度资源,且这些终端设备的半静态调度资源与已经激活的一组终端设备的半静态调度资源,以实现MBS数据的可靠接收;网络设备还可以针对所有终端设备统一进行半静态调度资源去激活,从而释放已经去激活的半静态调度资源,提高半静态调度资源的利用率。
基于包的数据流通常是突发性的,在没有数据传输的时候,可以通过关闭UE的接收电路来降低功耗,从而提升电池使用时间。这就是不连续接收(discontinuous reception,DRX)模式的由来。连接态的不连续接收(connected discontinuous reception,c-DRX)为应用于无线资源控制-连接态(RRC_CONNTECTED)UE的DRX机制。
如图9所示,c-DRX的基本机制是为处于RRC_CONNECTED态的UE配置一个不连续接收周期(DRX cycle)。DRX cycle由“苏醒期间(on duration)”和“不连续接收机会(Opportunity for DRX)(或者称休眠期间)”组成。在苏醒期间,UE监听并接收PDCCH(激活期);在“休眠期间,UE不接收下行信道的PDCCH数据以节省功耗。
然而,配置接收MBS数据的一组UE中如果存在UE在苏醒期间未被激活SPS资源而进入休眠期间,错过后续网络设备利用SPS调度的MBS数据。
有鉴于此,本申请实施例提供一种半静态调度方法,终端设备在非连续接收模式的苏醒期间接收重传数据包,将苏醒期间延长第一时间段,并在延长的苏醒期间检测激活命令,该激活命令用于激活半静态调度资源,从而,可以提高终端设备接收SPS资源的激活命令的可靠性。
下面将结合图9至图11对本申请实施例提供的半静态调度方法进行具体阐述。
如图10所示,为本申请实施例提供的一种半静态调度方法的流程示意图,示例性地,该方法包括以下步骤:
S301、终端设备在非连续接收模式的苏醒期间接收重传数据包。
网络设备统一对接收某一MBS业务的一组UE的SPS资源进行激活,激活命令采用组的RNTI加扰,并且使用组的RNTI调度数据的重传(即调度数据重传的命令采用同一个组RNTI加扰)。
对于网络设备发送组的RNTI加扰的信息对配置给某一MBS业务的一组UE的SPS资源进行激活时,该组UE存在以下状态:
1)类型1的UE:成功接收并解码激活命令,并成功接收SPS资源上传输的MBS数据,则向网络设备发送ACK;
2)类型2的UE:成功接收并解码激活命令,但未成功接收到SPS资源上传输的MBS数据,则向网络设备发送NACK;
3)类型3的UE:未接收到或未成功解码激活命令。
由于该组UE中有UE未能成功接收数据包,则网络设备使用组的RNTI调度数据的重传。由于对此MBS业务感兴趣或正在接收此MBS业务的UE均会监听此组的RNTI,则在接收到重传数据包后,对于上述三种类型的UE的行为为:
1)类型1的UE:什么都不做;
2)类型2的UE:接收并解码重传数据包,如果成功则返回ACK,不成功则返回NACK;
3)类型3的UE:如图11所示,该UE在DRX模式的苏醒期间可能接收到了重传数据包,可以通过调度重传数据的DCI(采用组RNTI加扰)判断出是SPS的重传,但是该UE未被激活SPS资源,不知道下一个SPS资源的时域位置在哪里。由于该UE被配置成DRX模式,该UE可能会根据DRX的配置和工作情况而进入休眠。如果UE不会在网络设备重新发送SPS激活命令的时机醒来,则仍然无法接收激活命令,也无法接收SPS资源上承载的MBS数据。从而UE发生丢包或无法接收MBS数据,降低业务传输/服务质量和用户体验。在图11的示例中,UE3未被激活SPS资源,却在苏醒期间接收到重传(re-transmission,RE)数据包,UE3之后进入休眠期间,对于网络设备在其休眠期间发送的DCI和SPS2等都接收不到。
S302、终端设备将苏醒期间延长第一时间段。
本实施例中,UE将自身的苏醒期间延长一个时间段,例如延长第一时间段。即无论UE的DRX处于哪个定时器激活的状态,在收到调度SPS重传数据包的DCI时,均在此时把定时器再延长一个第一时间段。可选地,该第一时间段可以是至少一个SPS周期,或者直至UE接收到激活命令。
可替换地,也可以是网络设备在调度SPS重传数据包的DCI中指示UE后面将会激活命令,和/或UE不要进入休眠状态。进一步地,UE在接收到激活命令后,可以继续运行现有DRX机制。
目前可以通过MAC CE向UE发送不连续接收命令(DRX command),指示UE立刻进入休眠状态。可替换地,在本实施例中,也可以是通过MAC CE向UE发送指示信息,用于指示UE不要进入休眠状态。
S303、终端设备在延长的苏醒期间检测激活命令,该激活命令用于激活半静态调度资源。
由于延长了苏醒期间,从而UE可以在延长的苏醒期间检测SPS资源的激活命令。继续参考图11,UE在延长的苏醒期间接收到了网络设备发送的DCI,还可以接收到网络设备在SPS2上发送的数据。UE在被激活SPS资源后,在休眠期间到达时,可以进入休眠状态。后续UE可以根据SPS资源的周期,接收后续的SPS资源上的数据。
根据本申请实施例提供的一种半静态调度方法,终端设备在非连续接收模式的苏醒期间接收重传数据包,将苏醒期间延长第一时间段,并在延长的苏醒期间检测激活命令,该激活命令用于激活半静态调度资源,从而,可以提高终端设备接收SPS资源的激活命令的可靠性。
如前所述,网络的下行调度模式分为动态调度模式和SPS调度模式,UE在接收下行调度信息时,通过使用不同的RNTI解扰不同格式的DCI,接收后续调度的信息。不同的调度模式,可以不同的RNTI加扰相应的DCI。从而UE可以区分网络是以哪种调度模式调度的,准确地解调下行调度信息,避免后续不能可靠地接收下行调度数据。
有鉴于此,本申请实施例提供一种MBS业务的下行调度方案,终端设备根据与确定的下行调度模式对应的RNTI解扰下行调度信息,提高了下行调度的可靠性。
如图12所示,为本申请实施例提供的一种下行调度方法的流程示意图,示例性地,该 方法包括:
S401、网络设备向终端设备发送下行调度信息。相应地,终端设备接收该下行调度信息。其中,该下行调度信息用于调度下行数据,该下行调度采用第一下行调度模式。
该第一下行调度模式可以是动态调度,也可以是SPS调度,还可以是动态调度和SPS调度。若该第一下行调度模式是动态调度,则该下行调度信息可以是DCI;若该第一下行调度模式是SPS调度,则该下行调度信息可以是DCI,RRC,MAC CE,广播信息等;若该第一下行调度模式是动态调度和SPS调度,则可以分别发送对应的下行调度信息。
S402、终端设备确定第一下行调度模式以及对应的无线网络临时标识解扰下行调度信息和/或DCI格式。
本实施例中,不同的下行调度模式可以具有对应的RNTI。UE确定了与第一下行调度模式后,确定对应的RNTI以及DCI格式,才能正确地解扰下行调度信息,从而利用解扰后的下行调度信息接收下行调度数据。
UE确定与第一下行调度模式对应的RNTI的方式有多种,下面分别进行描述:
实现方式1,若第一下行调度模式是动态调度或SPS调度中的任一种,则网络设备可以发送RRC给UE,该RRC用于指示第一下行调度模式是动态调度或SPS调度。例如,RRC中包括1比特信息,该比特值为“0”表示调度模式为动态调度,该比特值为“1”表示调度模式为SPS调度。反之亦可。UE接收到RRC后,获取RRC中的该比特信息,从而可以获得其指示的调度模式。在此实施方式中,第一下行调度模式对应的DCI可以采用一个RNTI加扰,也就是动态调度和SPS调度信息(DCI)使用相同的RNTI进行加扰,比如G-RNTI。
实现方式2,若第一下行调度模式是动态调度或SPS调度中的任一种,则网络设备可以通过DCI指示第一下行调度模式。可选的,动态调度以及SPS调度采用相同的DCI格式。UE解码DCI,确定第一下行调度模式为动态调度或SPS调度中。比如说,该DCI中也可以包括1比特信息,该比特信息用于指示第一下行调度模式是动态调度或SPS调度。例如,该比特值为“0”表示调度模式为动态调度,该比特值为“1”表示调度模式为SPS调度。反之亦可。该DCI可以采用G-RNTI加扰,网络设备和UE可以预先协商采用G-RNTI加扰该DCI,则该DCI是用于动态调度或SPS调度。则UE接收到该DCI,用G-RNTI解扰该DCI后,就可确定是动态调度或SPS调度。
实现方式3,网络设备在发送下行调度信息之前,发送SPS资源配置信息给终端设备,终端设备解码该SPS资源配置信息,可以确定该下行调度信息是进行SPS资源激活,该下行调度模式为SPS调度模式。
实现方式4,网络设备还可以和终端设备通过预先协商的方式确定下行调度模式。
实现方式5,若第一下行调度模式包括动态调度和SPS调度,则网络设备可以通过上述4种实现方式分别通知每个下行调度信息采用的下行调度模式。用于动态调度和SPS调度的DCI采用不同的RNTI进行加扰,比如动态调度采用G-RNTI,SPS调度采用专用于半静态调度的RNTI加扰DCI。
根据本申请实施例提供的一种下行调度方法,终端设备根据与确定的下行调度模式对应的RNTI解扰下行调度信息,提高了下行调度的可靠性。
可以理解的是,以上各个实施例中,由终端设备实现的方法和/或步骤,也可以由可用于终端设备的部件(例如芯片或者电路)实现;由网络设备实现的方法和/或步骤,也可以由可用于网络设备的部件(例如芯片或者电路)实现。

本申请实施例可以根据上述方法实施例中对终端设备和网络设备进行功能模块的划分,例如,可以对应各个功能划分各个功能模块,也可以将两个或两个以上的功能集成在一个处理模块中。上述集成的模块既可以采用硬件的形式实现,也可以采用软件功能模块的形式实现。需要说明的是,本申请实施例中对模块的划分是示意性的,仅仅为一种逻辑功能划分,实际实现时可以有另外的划分方式。
