本公开涉及通信技术领域,尤其是涉及一种数据传输方法、装置、网络侧设备及终端。
当用户配置一个非连续接收(Discontinuous Reception,DRX)组时,用户设备(User Equipment,UE)将对所有服务小区进行不连续的监听物理下行控制信道(Physical Downlink Control Channel,PDCCH)。在DRX周期内,UE只在激活期(On duration)内监测PDCCH,在“Opportunity for DRX”即非激活期(DRX off)时间内,UE不接收除调度广播信令之外的其他PDCCH,以减少功耗,即进入睡眠模式。
DRX机制主要对以下无线网络临时标识(Radio Network Tempory Identity,RNTI)加扰的PDCCH在非激活期不进行监听,具体有:小区无线网络临时标识(Cell Radio Network Tempory Identity,C-RNTI)、控制信息无线网络临时标识(Control Information Radio Network Tempory Identity,CI-RNTI)、配置调度无线网络临时标识(Configured Scheduling Radio Network Tempory Identity,CS-RNTI)、中断无线网络临时标识(Interruption Radio Network Tempory Identity,INT-RNTI),时隙格式指示无线网络临时标识(Slot Format Indication RNTI,SFI-RNTI)、半持续信道状态信息无线网络临时标识(Semi Persistent-Channel State Information,SP-CSI-RNTI)、发射功率控制无线网络临时标识(Transmit Power Control Physical Uplink Control Channel Radio Network Tempory Identity,TPC-PUCCH-RNTI)、发射功率控制物理上行共享信道无线控制网络临时标识(Transmit Power Control Physical Uplink Shared Channel Radio Network Tempory Identity,TPC-PUSCH-RNTI)、发射功率控制探测参考信号无线网络临时标识(Transmit Power Control-Sounding Reference,TPC-SRS-RNTI)以及AI-RNTI。其中,C-RNTI主要用于数据调度的下行控制信息(Downlink Control Information,DCI)加扰。
可见,相关的DRX机制,对于调度相关的RNTI受DRX激活期参数配置影响,因此,DRX参数配置上需要考虑多个业务的综合影响,使得DRX周期配置很难与具体业务相匹配,这样,会引入不必要的等待传输时延。

下面将结合本公开实施例中的附图,对本公开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公开一部分实施例,并不是全部的实施例。基于本公开中的实施例,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,都属于本公开保护的范围。
本公开实施例提供的技术方案可以适用于多种系统,尤其是5G系统。例如适用的系统可以是全球移动通讯(Global System of Mobile Communication,GSM)系统、码分多址(Code Division Multiple Access,CDMA)系统、宽带码分多址(Wideband Code Division Multiple Access,WCDMA)通用分组无线业务(General Packet Radio Service,GPRS)系统、长期演进(Long Term Evolution,LTE)系统、LTE频分双工(Frequency Division Duplex,FDD)系统、LTE时分双工(Time Division Duplex,TDD)系统、高级长期演进(Long Term Evolution Advanced,LTE-A)系统、通用移动系统(Universal Mobile Telecommunication System,UMTS)、全球互联微波接入(Worldwide interoperability for Microwave Access,WiMAX)系统、5G新空口(New Radio,NR)系统等。这多种系统中均包括终端设备和网络侧设备。系统中还可以包括核心网部分,例如演进的分组系统(Evloved Packet System,EPS)、5G系统(5G System,5GS)等。
本公开实施例涉及的终端,可以是指向用户提供语音和/或数据连通性的 设备,具有无线连接功能的手持式设备、或连接到无线调制解调器的其他处理设备等。在不同的系统中,终端的名称可能也不相同,例如在5G系统中,终端可以称为用户设备(User Equipment,UE)。无线终端设备可以经无线接入网(Radio Access Network,RAN)与一个或多个核心网(Core Network,CN)进行通信,无线终端设备可以是移动终端设备,如移动电话(或称为“蜂窝”电话)和具有移动终端设备的计算机,例如,可以是便携式、袖珍式、手持式、计算机内置的或者车载的移动装置,它们与无线接入网交换语言和/或数据。例如,个人通信业务(Personal Communication Service,PCS)电话、无绳电话、会话发起协议(Session Initiated Protocol,SIP)话机、无线本地环路(Wireless Local Loop,WLL)站、个人数字助理(Personal Digital Assistant,PDA)等设备。无线终端设备也可以称为系统、订户单元(subscriber unit)、订户站(subscriber station),移动站(mobile station)、移动台(mobile)、远程站(remote station)、接入点(access point)、远程终端设备(remote terminal)、接入终端设备(access terminal)、用户终端设备(user terminal)、用户代理(user agent)、用户装置(user device),本公开实施例中并不限定。

下面结合附图,通过具体的实施例及其应用场景对本公开实施例提供的数据传输方法、装置、网络侧设备及终端进行详细地说明。
如图2所示,为本公开实施例的输出传输方法的步骤流程示意图之一,该方法包括:
步骤201,网络侧设备生成第一下行控制信息DCI;第一DCI用于调度第一业务;
步骤202,网络侧设备在非连续接收DRX激活期和/或DRX非激活期发送所述第一DCI。
本公开实施例的数据传输方法中,网络侧设备生成用于调度第一业务的第一DCI,并在DRX激活期和/或非激活期向终端发送所述第一DCI,如此,使得第一DCI为用于调度第一业务的DCI,实现了网络侧设备为终端配置专属的数据传输信息;并在DRX激活期和/或非激活期向终端发送第一DCI,使得终端能够在非连续接收DRX激活期和/或DRX非激活期内进行所述第一DCI的监听。如此,终端可以在DRX机制下不受DRX限制而根据业务特性进行相应的数据动态调度DCI监听,从而解决目前由于DRX参数配置上需要考虑多个业务的综合影响,使得DRX周期配置很难与具体业务相匹配而引入不必要的等待传输时延的问题,同时,也能保证其他业务的不连续接收。
需要说明的是,第一DCI可能包括第一业务的调度信息,也可能不包括第一业务的调度信息,第一DCI是否包括调度信息取决于第一业务的到达情况。
作为一个可选的实现方式,所述第一DCI采用与第一业务相关的专用标识加扰。
本可选的实现方式中,与第一业务相关的专用标识可以为业务专属的RNTI,如X-RNTI,用于业务传输的检测标识。其中,该业务标识RNTI加扰的DCI监听不受DRX控制,即在DRX非激活期,终端仍能进行第一DCI的监听。这样,实现了网络侧设备为终端配置专属的数据传输信息,且终端可以在DRX机制下不受DRX限制而根据业务特性进行相应的数据动态调度DCI监听,避免了由于DRX周期配置很难与具体业务相匹配而引入不必要的等待传输时延的问题。
进一步地,作为一个可选的实现方式,所述方法还包括:
所述网络侧设备为所述第一DCI配置DRX激活期内的第一搜索空间集和/或DRX非激活期内的第二搜索空间集;
其中,所述第一搜索空间集和所述第二搜索空间集相同或不同。
这里,需要说明的是,在所述网络侧设备为所述第一DCI配置DRX激活期内的第一搜索空间集和/或DRX非激活期内的第二搜索空间集的基础上,终端可以仅在DRX激活期采用该第一搜索空间集监听第一DCI,或者,终端可以仅在DRX非激活期采用该第二搜索空间集监听第一DCI,或者,终端在 DRX激活期采用网络侧设备配置的第一搜索空间集监听第一DCI,并在DRX非激活期采用网络侧设备配置的第二搜索空间集监听第一DCI。
这里,还需要说明的是,网络侧设备在为第一DCI配置第一搜索空间集和第二搜索空间的情况下,终端可以在DRX激活期和DRX非激活期采用相同或不同的搜索空间集监听第一DCI;其中,搜索空间集参数可以包括监听周期、带宽部分(BandWidth Part,BWP)、聚合等级(Aggregation Level,AL)、发送/接收天数的数量、发射/接收层数、发射/接收层数最大层数据等,但不以此为限。网络侧设备为第一DCI配置多个搜索空间集的具体示例如下:
示例一:网络侧设备为X-RNTI加扰的DCI(第一DCI)配置多套搜索空间集参数,例如:网络侧设备对DRX激活期和DRX非激活期配置的搜索空间集分别为搜索空间集1和搜索空间集2,这样,在DRX激活期,终端采用搜索空间集1对X-RNTI加扰的DCI(第一DCI)进行监听,在DRX非激活期,终端采用搜索空间集2对X-RNTI加扰的DCI(第一DCI)进行监听。
示例二:网络侧设备可以为X-RNTI加扰的DCI(第一DCI)配置一套搜索空间集参数,且在该套搜索空间集中配置多套参数。这里,以监听周期为例,X-RNTI加扰的DCI(第一DCI)的搜索空间集中配置监听周期1和监听周期2,分别对应DRX的激活期和非激活期,其中,监听周期1小于监听周期2,从而在DRX非激活期可以配置较稀疏的监听行为。
这里,还需要说明的是,第一DCI的配置方法,可以与相关的DCI的搜索空间集配置方法相同,还可以从终端节能的角度采用上述网络侧设备为第一DCI配置至少一个搜索空间集的配置方法。其中,相关的DCI的搜索空间集配置方法如下:
网络侧设备通过系统消息为用户分配一个或多个搜索空间(Search Space),每个搜索空间的配置是周期性的,终端在配置的搜索空间进行DCI检测。终端每次进行DCI检测的时刻称为DCI监听机会(DCI monitoring occasion)。搜索空间一般是周期性配置,在5G NR系统中,终端为了获得下行调度信息,需要在每个DCI监听机会对DCI进行监听,来判断是否有下行调度信息,每次DCI监听的过程是一次DCI译码过程,然后根据循环冗余校验码(Cyclic redundancy check,CRC)校验结果判断为携带UE调度信息的 DCI。如果DCI有终端的调度信息,那么UE可以获得正的CRC校验,同时,可以获得DCI中携带的调度信息;否则,CRC校验为负值,UE无法获得DCI中的任何信息。
对于DCI的参数配置如下:
搜索空间集和的索引,即:Search Space ID;
用于建立搜索空间s与控制资源集合p联系的控制资源集合编号,即CORESET ID;
DCI监听周期k
p,s以及偏移值o
p,s,其单位均为时隙(slot),终端根据此配置参数确定监听DCI的时隙;
DCI在slot内的监听图样;
用于区分当前搜索空间为公共搜索空间还是终端专属搜索空间的标志searchspace Type。
本可选实现方式中,网络侧设备为第一DCI配置至少一个搜索空间集,使得终端能够在DRX激活期或DRX非激活期采用配置的搜索空间集监听第一DCI,或者,能够在DRX激活期和DRX非激活期采用相同或不同的搜索空间集监听第一DCI,如此,实现了在DRX机制下不受DRX限制而根据业务特性进行相应的数据动态调度DCI监听,避免了不必要的等待时延也不会影响其它业务的传输。
进一步地,作为一个可选的实现方式,所述方法还包括:
所述网络侧设备向终端发送第一指示信息,所述第一指示信息用于指示以下至少一项:
所述终端在DRX激活期进行监听跳过和/或休眠;
所述终端在DRX非激活期进行监听跳过和/或休眠。
这里,需要说明的是,第一指示信息可以承载于第一DCI,还可以通过其他非激活期可接收的信令承载,如:层1信令、节能信号、媒体接入控制(Media Access Control,MAC)层信令和高层信令等。其中,所述第一指示信息承载于第一DCI以外的其他信令时,网络侧设备发送所述第一指示信息 和所述第一DCI没有绝对的先后顺序,可以第一DCI与第一指示信息同时发送,也可以在发送第一DCI之前发送所述第一指示信息,还可以在发送所述第一DCI之后发送所述第一指示信息。
这里,需要说明的是,第一指示信息为终端节能指示信息,网络侧设备可以在DRX激活期通过该第一指示信息指示终端进行后续的监听跳过和/或休眠,或者,网络侧设备在DRX非激活期,通过包括第一指示信息的第一DCI、层1信令、节能信号、MAC层信令和高层信令等至少一个信令进行后续监听跳过和/或休眠,以指示终端进行不连续的第一DCI监听行为,从而节省一定功耗的同时,还能减少第一业务的等待时延。
这里,还需要说明的是,在所述第一指示信息指示终端在DRX激活期进行监听跳过和/或休眠时,第一指示信息指示的内容具体可以为以下至少一项:终端在当前监听窗口内或DRX非激活期内的监听机会进行监听跳过和/或休眠;即:终端在当前监听窗口内的剩余的监听机会进行监听跳过和/或休眠;终端在当前DRX激活期内已配置的剩余的监听位置进行监听跳过和/或休眠。在所述第一指示信息指示终端在DRX非激活期进行监听跳过和/或休眠时,第一指示信息指示的内容具体可以为以下至少一项:终端在当前监听窗口内或DRX非激活期内的监听机会进行监听跳过和/或休眠;即:终端在当前监听窗口内或DRX非激活期内的监听机会进行监听跳过和/或休眠;终端在当前监听窗口内的剩余的监听机会进行监听跳过和/或休眠;终端在当前DRX非激活期内已配置的剩余的监听位置进行监听跳过和/或休眠。
进一步地,作为一个可选的实现方式,所述方法还包括:
所述网络侧设备配置第一DCI的监听位置信息;其中,所述第一DCI的监听位置信息包括以下至少一项:
DRX激活期内第一DCI的第一监听位置信息;
DRX非激活期内第一DCI的第二监听位置信息。
这里,需要说明的是,第一监听位置信息和第二监听位置信息可以相同或不同。
这里,还需要说明的是,第一DCI可以采用C-RNTI加扰,或者,采用与第一业务相关的专用标识加扰。其中,在DRX激活期,终端可以根据网络 侧设备配置的第一监听位置信息和/或第一搜索空间集进行第一DCI的监听;在DRX非激活期,终端可以根据网络侧设备配置的第二监听位置信息和/或第二搜索空间集进行第一DCI的监听。
本可选的实现方式中,通过网络侧设备配置第一DCI的监听位置信息,使得终端能够根据第一DCI的监听位置信息,监听第一DCI,如此,实现了终端可以在DRX机制下不受DRX限制而根据业务特性进行相应的数据动态调度DCI监听,从而解决目前由于DRX参数配置上需要考虑多个业务的综合影响,使得DRX周期配置很难与具体业务相匹配而引入不必要的等待传输时延的问题,同时,也能保证其他业务的不连续接收。
作为一个可选的实现方式,所述网络侧设备配置第一DCI的监听位置信息,包括以下至少一项:
所述网络侧设备通过高层信令半静态配置所述监听位置信息;
所述网络侧设备通过第一信息动态配置所述监听位置信息。
本可选实现方式中,网络侧设备通过第一信息动态配置所述监听位置信息,实现了对第一DCI的监听位置进行动态调整。具体如下:
网络侧设备可以在DRX非激活期配置第一业务专属的监听位置信息,同时,网络侧设备为终端配置第一信息,用于指示终端在监听到业务专属DCI之后继续监听的时间。其中,第一信息可以通过层1信令或MAC信令或高层信令携带,例如:第一信息可以是监听计时器或持续时间,也可以是指示信令信息,也可以是参考信号。以监听计时器为例,当监听计时器未超时时,终端可以继续进行业务专属DCI监听(第一DCI)。当业务数据包因时延抖动而在监听窗口结束时进行数据传输时,由于后续没有监听机会而导致数据包需要等下一个监听窗口或监听机会才能传输,配置监听计时器有利于减小因时延抖动而引起的传输时延。
可选的,当网络侧设备完成数据传输,则通过第一指示信息指示终端跳过监听或休眠。
作为一个具体的实现方式,半静态配置的监听位置信息包括:
所述第一DCI的监听窗口和/或监听起始位置信息。
也就是说,半静态配置的监听位置信息可以包括用于监听第一DCI的监 听窗口,和/或,包括监听第一DCI的监听起始位置。
作为一个可选的实现方式,半静态配置的所述监听位置信息,包括以下至少一项:
与第一行为相关联的位置信息;
独立的监听位置信息。
这里,需要说明的是,第一行为可以为周期性或半持续性行为或非周期性行为;其中,周期性或半持续性行为包括以下至少一项:

下面,结合具体的实例对本公开实施例的数据传输方法的具体实现进行说明:
实例一:第一DCI采用与第一业务相关的专用标识加扰,终端在DRX的激活期和DRX的非激活期均可以监听第一DCI:
引入业务专属的业务标识(第一业务的专用标识),用于业务传输的检测标识,如:业务专属的RNTI,如X-RNTI,该业务标识RNTI加扰的DCI监听不受DRX控制,即:在DRX非激活期,终端仍能进行相应的DCI监听,本实例以X-RNTI为例进行说明。
对于业务X(第一业务)的通过XRNTI加扰调度DCI进行数据调度,在DRX的激活期和非激活期均可以进行监听。调度DCI的配置方法可以同相关DCI搜索空间集配置方法相同,也可以从终端节能的角度采用以下方法中的至少一种:
方法1:为X-RNTI加扰DCI(第一DCI)配置多套搜索空间集参数,或一套搜索空间集参数中配置多套参数。例如:在DRX激活期,终端采用搜索空间集1对X-RNTI加扰的DCI的进行监听,在DRX非激活期,终端采用搜索空间集2对X-RNTI加扰的DCI的进行监听;还可以是网络侧设备对DRX激活期和DRX非激活期配置的搜索空间集分别为搜索空间集1和搜索空间集 2。又例如:X-RNTI加扰的DCI的搜索空间集中配置监听周期1和监听周期2,分别对应DRX的激活期和非激活期,即在DRX激活期采用监听周期1对X-RNTI加扰的DCI进行监听,在DRX非激活期采用监听周期2对X-RNTI加扰的DCI进行监听。在DRX非激活期可以配置较稀疏的监听行为。
方法2:在X-RNTI加扰DCI(第一DCI)中携带终端节能指示信息(第一指示信息),如:监听跳过指示和/或休眠指示。例如:终端在DRX激活期可以通过包括第一指示信息的第一DCI、层1信令、节能信号、MAC层信令和高层信令等至少一个信令进行后续监听跳过或休眠指示。在DRX非激活期,可以通过包括第一指示信息的第一DCI、层1信令、节能信号、MAC层信令和高层信令等至少一个信令进行后续监听跳过或休眠指示终端进行不连续的PDCCH监听行为,从而节省一定功耗的同时,还能减少X业务的等待时延。
这里,需要说明的是,对于采用C-RNTI加扰的第一DCI,也可以采用本实例中的方法进行第一DCI的监听。
这里,还需要说明的是,对于仅在DRX激活期对第一DCI进行监听的实现方式,与本实例中在DRX激活期对第一DCI进行监听的实现方式类似。
实例二:第一DCI采用与第一业务相关的专用标识加扰,终端仅在DRX的非激活期监听第一DCI:
引入业务专属的业务标识(第一业务的专用标识),用于业务传输的检测标识,如:业务专属的RNTI,如X-RNTI,该业务标识RNTI加扰的DCI监听不受DRX控制,即:在DRX非激活期,终端仍能进行相应的DCI监听,本实例以X-RNTI为例进行说明。
对于业务X(第一业务)的通过X-RNTI加扰调度DCI进行数据调度,X-RNTI加扰的DCI仅在DRX非激活期进行监听。
网络侧设备为终端配置X-RNTI加扰的DCI(第一DCI)的搜索空间配置,具体的参数可以与搜索空间集参数一致。但考虑到X-RNTI加扰的DCI需要在DRX非激活期进行监听,从节能的角度,X-RNTI加扰的DCI的搜索空间还可以采用以下方法中的一种:
方法1:X-RNTI加扰的DCI(第一DCI)的搜索空间配置较大数值的监听周期,其中,较大数值是指DRX非激活期内的监听周期大于DRX激活期 内的监听周期。
方法2:在X-RNTI加扰DCI(第一DCI)中携带终端节能指示信息(第一指示信息),如:监听跳过指示和/或休眠指示。例如:终端在DRX激活期可以通过包括第一指示信息的第一DCI、层1信令、节能信号、MAC层信令和高层信令等至少一个信令进行后续监听跳过或休眠指示。在DRX非激活期,可以通过包括第一指示信息的第一DCI、层1信令、节能信号、MAC层信令和高层信令等至少一个信令进行后续监听跳过或休眠指示终端进行不连续的PDCCH监听行为,从而节省一定功耗的同时,还能减少X业务的等待时延。
当终端处于DRX激活期时,第一业务的数据包通过C-RNTI加扰的调度DCI进行数据调度,即第一DCI采用C-RNTI加扰,当影响DRX激活期的定时器,如:DRX激活期定时器(drx-onDurationTimer)、DRX非激活定时器(drx-InactivityTimer)等超时时,终端进入非激活期。由于第一业务对传输时延的要求相对较高,为了避免终端等待下一个DRX激活期,而引入不必要的传输时延,本可选实现方式中,终端基于预配置的参数对采用第一业务的专用标识加扰第一DCI进行监听。
这里,需要说明的是,对于采用C-RNTI加扰的第一DCI,也可以采用本实例中的方法进行第一DCI的监听。
实例三:业务专属的业务标识X-RNTI(与第一业务相关的专用标识),通过层1信令/MAC层信令/高层信令等信令指示X-RNTI加扰的DCI(第一DCI)的监听方式。
引入业务专属的业务标识(与第一业务相关的专用标识),用于业务传输的检测标识,如:业务专属的RNTI,如X-RNTI,该业务标识RNTI加扰的DCI监听不受DRX控制,即:在DRX非激活期,终端仍能进行相应的DCI监听,本实例以X-RNTI为例进行说明。
对于业务X的通过X-RNTI加扰调度DCI进行数据调度,X-RNTI加扰的DCI是否在DRX非激活期进行监听,由业务专属监听指示进行指示。业务专属监听指示可以通过L1/MAC层信令/高层信令等信令携带。
网络侧设备为终端配置X-RNTI加扰的DCI(第一DCI)的搜索空间配置,具体的参数可以与搜索空间集参数一致。网络侧设备可以根据业务传输 情况向终端发送业务专属监听指示信息(第三指示信息)通知终端是否在DRX激活期和/或DRX非激活期进行X-RNTI加扰的DCI监听,具体可以采用以下几种方法之一:
方法1:L1信令携带业务专属监听指示信息(第三指示信息)。
当网络侧设备确定当前业务是X业务时,通过DRX激活期的调度DCI信令/非调度DCI信令携带业务专属监听指示,指示终端在DRX激活期和/或DRX非激活期进行业务专属的DCI监听。也可以在DRX非激活期通过非调度DCI携带业务专属监听指示,指示终端在DRX非激活期进行业务专属的DCI监听,也可以在DRX非激活期通过节能信号携带第三指示信息,指示终端在DRX激活期和/或DRX非激活期进行第一DCI的监听。
方法2:MAC CE携带业务专属监听指示信息(第三指示信息)。
网络侧设备可以通过DRX激活期的PDSCH中的MAC CE携带业务专属监听指示,用于指示终端在DRX激活期和/或DRX非激活期进行业务专属的DCI(第一DCI)监听。还可以通过DRX非激活期的SPS PDSCH携带业务专属指示,指示终端在DRX非激活期进行业务专属的DCI监听。
方法3:高层信令携带业务专属监听指示(第三指示信息)。
网络侧设备通过高层信令配置业务专属监听指示信息,当取值为第一值(如第一值为1)时,指示终端在DRX非激活期进行业务专属的DCI监听;当取值为值第二值(如第二值为2)或缺省时,指示终端在DRX非激活期不用进行业务专属的DCI监听。
这里,需要说明的是,对于采用C-RNTI加扰的第一DCI,也可以采用本实例中的方法进监听方式的指示。
实例四:网络侧设备配置业务专属的监听位置信息,即第一DCI的监听位置信息(包括监听窗口和/或监听起始位置信息)。
在DRX非激活期配置业务专属的第二监听位置信息。在DRX激活期,终端按激活期配置的DCI搜索空间进行监听;在DRX非激活期,终端按预配置的第二监听位置信息进行调度DCI(第一DCI)监听。
网络侧设备通过高层信令预配置DRX激活期和/或DRX非激活期内X业务专属的监听位置信息。对于X业务专属的监听位置信息可以采用的配置 方法有以下参数的一种或几种组合:
通过监听周期periodicity和offset配置监听起始时间;
监听窗口的起始时间T
start;
监听持续时间duration;
终止时间T
final;
相邻监听窗口之间的时间间隔T
offset;
非激活期监听起始位置/监听窗口的个数;
激活期监听起始位置/监听窗口的个数;
与现有第一行为的起始位置/结束位置的偏移值offset作为监听起始时间,第一行为包括周期性或半持续性行为,如:周期性CSI/RRM/RLM测量、SPS PDSCH所在时隙、SPS PDSCH的HARQ-ACK反馈所在时隙、SPS PDSCH的RTT定时器开启或超时时、DRX周期/激活期的起始位置/结束位置、SSB/CSI-RS/TRS等周期性参考信号等。第一行为还包括非周期性行为,如:下行信令,CSI测量,参考信号,如CSI-RS、TRS等。
对于上述参数具体举例说明监听窗口和/或监听起始位置的配置方法:
示例一:通过监听周期periodicity和offset配置监听起始时间,例如:起始时间满足以下条件:
其中,n
f为帧号,
为子载波μ下的时隙号,
为子载波μ下一个子帧所包含的时隙数,k
s为监听周期,o
s为第一偏移值。此外,如果配置监听持续时间duration,则可以确定一个或多个监听窗口。也可以结合配置相邻监听窗口之间的时间间隔T
offset和/或DRX非激活期/DRX激活期监听起始位置/监听窗口的个数,确定多个监听窗口。
示例二:通过配置监听窗口的绝对起始时间T
start和监听终止时间T
final或监听持续时间duration,确定一个监听窗口。此外,如果配置了相邻监听窗口之间的时间间隔T
offset和/或监听起始位置/监听窗口的个数,则可以确定多个监听窗口。
示例三:监听窗口或监听起始位置可以与现有周期性行为的起始位置/结束位置的偏移值offset作为监听起始时间。这里的偏移值可以是在周期性行为的起始位置/结束位置之后的偏移值位置,也可以在周期性行为的起始位置 /结束位置之前的偏移值位置。
当网络侧设备接收到核心网发送X业务指示,或网络侧设备识别出下行数据业务指示为X业务,网络侧设备可以通过X业务指示信息(第三指示信息)通知终端,当前业务是X业务。也可以是终端应用层识别出当前业务是X业务。这里,需要说明的是,对于终端应用层识别之前,采用原有的数据传输方案,比如数据传输出气是以DRX激活期开始。
当数据传输业务为X业务时,终端可以根据预配置的监听窗口或监听机会在DRX激活期和/或DRX非激活期内进行X业务的调度DCI的监听。
从节能的角度考虑,还可以采用以下方法:
在第一DCI中携带终端节能指示(第一指示信息),如:监听跳过指示和/或休眠指示。例如:终端在DRX非激活期可以通过包括第一指示信息的第一DCI、层1信令、节能信号、MAC层信令和高层信令等至少一个信令指示终端进行不连续的DCI监听行为,从而节省一定功耗的同时,还能减少X业务的等待时延。
实例五:X-RNTI(第一业务的专用标识)加扰的DCI仅在DRX非激活期内的监听窗口和/或监听起始位置进行监听。
网络侧设备对于X业务的调度DCI配置业务专属标识,如X-RNTI。X-RNTI加扰的DCI不受DRX非激活期的限制,即可以在DRX非激活期进行监听。对于X-RNTI加扰的DCI在DRX激活期内可以进行监听,也可以不进行监听,具体参见实例一和实例二。
当终端处于DRX非激活期时,终端在预配置的监听窗口和/或监听起始位置进行监听X-RNTI加扰的DCI。具体过程可详见实施四。
实例六:对于第一业务的专用标识,还可以扩展用于同一业务的不同类型数据传输,例如:视频流业务中的I帧、P帧以及B帧。当核心网可以对不同编码的数据流进行指示时,网络侧设备可以利用不同编码的数据流的传输优先级,对其配置专属的业务流标识,例如:X-RNTI等。具体的传输方案可以参见实例一至五。
实例七:X业务的监听窗口大小可以基于第一信息进行动态调整。
在DRX非激活期配置业务专属的监听位置信息。举例说明:在DRX激 活期,终端按激活期配置的PDCCH搜索空间进行监听,在DRX非激活期,终端按预配置的监听位置信息(监听窗口或监听起始位置)进行调度DCI监听。
同时,网络侧设备为终端配置第一信息,用于指示终端在监听到业务专属DCI之后继续监听的时间。
第一信息可以通过L1信令或MAC信令或高层信令携带。例如:第一信息可以是监听计时器或持续时间,也可以是指示信令信息,也可以参考信号。以监听计时器为例,当监听计时器未超时时,终端可以继续进行业务专属DCI监听。当业务数据包因时延抖动而在监听窗口结束时进行数据传输时,由于后续没有监听机会而导致数据包需要等下一个监听窗口或监听机会才能传输,配置监听计时器有利于减小因时延抖动而引起的传输时延。
当网络侧设备完成数据传输,则通过第一指示信息指示终端跳过监听或休眠。具体过程同实施一至四。
