值得指出的是,本申请实施例所描述的技术不限于长期演进型(Long Term Evolution,LTE)/LTE的演进(LTE-Advanced,LTE-A)系统,还可用于其他无线通信系统,诸如码分多址(Code Division Multiple Access,CDMA)、时分多址(Time Division Multiple Access,TDMA)、频分多址(Frequency Division Multiple Access,FDMA)、正交频分多址(Orthogonal Frequency Division Multiple Access,OFDMA)、单载波频分多址(Single-carrier Frequency-Division Multiple Access,SC-FDMA)和其他系统。本申请实施例中的术语“系统”和“网络”常被可互换地使用,所描述的技术既可用于以上提及的系统和无线电技术,也可用于其他系统和无线电技术。然而,以下描述出于示例目的描述了新空口(New Radio,NR)系统,并且在以下大部分描述中使用NR术语,尽管这些技术也可应用于NR系统应用以外的应用,如第6代(6 th Generation,6G)通信系统。
参见图1,图中示出本申请实施例可应用的一种无线通信系统的框图。无线通信系统包括终端11、网络侧设备12,终端11之间可以通过Sidelink接口建立通信连接,终端11可以通过蜂窝网通信接口(Uu接口)与网络侧 设备12建立通信连接。其中,终端11也可以称作终端设备或者用户终端(User Equipment,UE),终端11可以是手机、平板电脑(Tablet Personal Computer)、膝上型电脑(Laptop Computer)或称为笔记本电脑、个人数字助理(Personal Digital Assistant,PDA)、掌上电脑、上网本、超级移动个人计算机(Ultra-Mobile Personal Computer,UMPC)、移动上网装置(Mobile Internet Device,MID)、可穿戴式设备(Wearable Device)或车载设备(Vehicle User Equipment,VUE)、行人终端(Pedestrian User Equipment,PUE)等终端侧设备,可穿戴式设备包括:手环、耳机、眼镜等。需要说明的是,在本申请实施例并不限定终端11的具体类型。
网络侧设备12可以是基站或核心网,其中,基站可被称为节点B、演进节点B、接入点、基收发机站(Base TransceiverStation,BTS)、无线电基站、无线电收发机、基本服务集(BasicServiceSet,BSS)、扩展服务集(ExtendedServiceSet,ESS)、B节点、演进型B节点(eNB)、家用B节点、家用演进型B节点、无线局域网(Wireless Local Area Networks,WLAN)接入点、无线保真(Wireless Fidelity,WiFi)节点、发送接收点(Transmitting Receiving Point,TRP)、无线接入网节点或所述领域中其他某个合适的术语,只要达到相同的技术效果,所述基站不限于指定技术词汇,需要说明的是,在本申请实施例中仅以NR系统中的基站为例,但是并不限定基站的具体类型。
为了便于理解本申请实施例,下面先介绍以下技术点:
1、关于副链路的介绍。
长期演进(Long Term Evolution,LTE)系统从第12个发布版本开始支持副链路(sidelink,或译为侧链路,边链路等),副链路用于UE之间不通过网络设备进行直接数据传输。
LTE sidelink的设计适用于特定的公共安全事务(如火灾场所或地震等灾难场所进行紧急通讯),或车联网(Vehicle To Everything,V2X)通信等。车联网通信包括各种业务,例如,基本安全类通信,高级(自动)驾驶,编队,传感器扩展等等。由于LTE sidelink只支持广播通信,因此主要用于基本安全类通信,其他在时延、可靠性等方面具有严格服务质量(Quality of Service, QoS)需求的高级V2X业务将通过新空口(New Radio,NR)sidelink支持。
第五代移动通信技术(5th generation,5G)NR系统可用于LTE不支持的6GHz以上工作频段,支持更大的工作带宽,但目前版本的NR系统只支持基站与终端间的接口,尚不支持终端之间直接通信的Sidelink接口。
Sidelink接口也可以称作PC5接口。
2、关于Sidelink的传输形式。
目前的sidelink传输包括广播(broadcast),组播(groupcast),单播(unicast)。单播是一对一(one to one)的传输。组播是一对多(one to many)的传输。广播也是one to many的传输,但是广播并没有UE属于同一个组的概念。
目前Sidelink传输中的单播和组播通信支持物理层混合自动重传请求(Hybrid Automatic Repeat reQuest,HARQ)反馈机制。
3、关于DRX。
非连续接收的目的是用于节电,处于DRX状态的终端不需要连接监听控制信道。但是如果终端长时间不监听控制信道,那么一旦有数据达到,将会增加数据传输的时延。为了兼顾省电和传输时延,根据终端监听信道的时间长短,5G媒体接入控制(Medium Access Control,MAC)支持两种DRX周期,长DRX周期和短DRX周期。如果预测终端数据量达到比较频繁或者业务对时延比较敏感,网络可以配置终端使用短DRX周期;如果预测终端数据量比较稀疏且时延不敏感,网络可以配置终端仅使用长DRX周期。为了便于终端进行长DRX周期/短DRX周期的切换,要求长DRX周期是短DRX周期的整数倍,这样保证两者的持续时间(onDuration)对齐。
为了支持DRX机制,基站会为终端配置DRX相关定时器和参数,具体包括:
(1)drx-LongCycleStartOffset:用于配置长DRX周期的周期和偏移,周期和偏移的单位可以是毫秒;
(2)drx-ShortCycle:用于配置短DRX周期的周期和偏移,周期和偏移的单位可以是毫秒;
(3)drx-ShortCycleTimer:用于控制终端使用短DRX周期的时长,单位为整数,表示终端一旦进入短DRX周期,要维持整数倍个短DRX周期;
(4)drx-onDurationTimer:DRX持续监听定时器,在该定时器运行期间,终端需要持续监听网络的物理下行控制信道(Physical Downlink Control Channel,PDCCH)控制信道。该定时器单位可以是毫秒;
(5)drx-SlotOffset:终端启动drx-onDurationTimer的时延,通过该参数设置DRX onDuration的起始时刻相对于子帧起点的偏移量,偏移量可以是1/32毫秒的整数倍;
(6)drx-InactivityTimer:DRX非激活定时器。该定时器在终端收到针对上/下行新数据调度PDCCH信令后的第一个符号启动,在该定时器运行期间,终端需要持续监听控制信道,该定时器的单位可以是毫秒;
(7)drx-HARQ-RTT-TimerDL:下行HARQ往返时延(Round-Trip Time,RTT)定时器,基于每个下行进程维护,定时器长度为从HARQ反馈时刻到收到针对该进程的HARQ重传之间的最小时间间隔。只有下行进程对应的数据未成功解码,终端才会在该进程的HARQ NACK反馈之后的第一个符号启动该定时器。如果当前终端只有drx-HARQ-RTT-TimerDL和/或drx-HARQ-RTT-TimerUL运行,则终端无需监听PDCCH控制信道,该定时器的单位可以是符号;
(8)drx-HARQ-RTT-TimerUL:上行HARQ RTT定时器,基于每个上行进程维护,该定时器长度为从上行物理共享信道(Physical Uplink Shared Channel,PUSCH)传输时刻到收到针对该进程的HARQ重传之间的最小时间间隔。上行PUSCH传输后,终端启动针对该上行进程的上行HARQ RTT定时器,如果PUSCH传输使用了PUSCH重复(PUSCH repetition),那么上行HARQ RTT定时器在PUSCH第一次重复后启动,以保证基站提前解析出PUSCH后,能够及时终止PUSCH重复传输。该定时器的单位可以是符号;
(9)drx-RetransmissionTimerDL:下行重传定时器,drx-HARQ-RTT-TimerDL超时后的下一个符号启动该定时器。该定时器运行期间,终端监听网络的控制信道,如果接收到针对该进程的下行调度信息或者下行配置授权(configured grant),则停止该定时器。该定时器的单位可以是时隙(time slot);
(10)drx-RetransmissionTimerUL:上行重传定时器, drx-HARQ-RTT-TimerUL超时后的下一个符号启动该定时器。该定时器运行期间,终端监听网络的控制信道,如果接收到针对该进程的上行调度信息或者上行configured grant,则停止运行。该定时器单位是时隙(time slot)。
现有的DRX机制是用于Uu接口,由网络侧通过UE专用RRC信令进行配置的,用于网络侧和UE之间的非连续接收。然而由于SL接口是两个或者多个UE之间,SL组播(groupcast),广播(broadcast),单播(unicast)的不同方式,如何进行SL DRX相关配置,目前没有解决方案。
下面结合附图,通过一些实施例及其应用场景对本申请实施例提供的一种副链路的非连续接收配置方法、装置、设备及可读存储介质进行详细地说明。

下面以发送端为TX UE,接收端为RX UE为例,介绍本申请几种可选的实施例。
实施例一:配置组播和广播业务的SL DRX参数。
因为组播和广播,比较不方便进行TX UE和RX UE之间的交互过程以确定SL DRX参数,因此可以采取统一配置的方式配置SL DRX参数。
可选地,统一配置SL DRX参数的方式包括如下一种或者多种组合:
(1)标准规定;
(2)Pre-configuration信令;
(3)SIB信令;
(4)V2X layer信令。
可选地,统一配置的SL DRX参数粒度,可以包括如下一种或者多种组合:
(1)所有的广播和组播业务,使用SL DRX参数集合0;
(2)广播业务,使用SL DRX参数集合1;
(3)组播业务,使用SL DRX参数集合2;
(4)广播业务中,公共安全(public safety)或者指定类型的业务,使用SL DRX参数集合3;
(5)广播业务中,商业(commercial)或者指定类型的业务,使用SL DRX参数集合4;
(6)组播业务中,public safety或者指定类型的业务,使用SL DRX参数集合5;
(7)组播业务中,commercial或者指定类型的业务,使用SL DRX参数集合6;
(8)广播业务中,满足QoS flow类型1的业务,使用SL DRX参数集合7;
(9)广播业务中,满足QoS flow类型2的业务,使用SL DRX参数集合8;
(10)组播业务中,满足QoS flow类型3的业务,使用SL DRX参数集合9;
(11)组播业务中,满足QoS flow类型4的业务,使用SL DRX参数集合10;
(12)组播或广播业务,发起指定业务,使用的SL DRX参数集合11。
相当于,TX UE和RX UE分别获得关于组播和广播业务的SL DRX参数集合,然后TX UE根据自己即将发起的业务类型,选择其中适合的一个SL DRX参数集合,进行业务的发送;RX UE根据自己感兴趣或者需要接收的业务类型,选择其中合适的一个或者多个SL DRX参数集合,进行业务的监听和接收,从而使得TX UE和RX UE可以按照相同的DRX图案(pattern)进行SL通信,既满足了不同业务需求也达到了RX UE省电的目的。
通过V2X layer信令统一配置SL DRX参数的方式如下:
由于该V2X layer信令可以用于TX UE和RX UE之间协商组和组业务的QoS需求等过程,那么在这个过程中,也可以一起协商关于SL DRX具体参数,也就是说通过V2X layer信令过程,可以为一组UE协商自己的SL DRX参数配置,这组TX UE和RX UE可以获得一组不同于公共信令中的SL DRX参数。
需要说明的是,由于广播或组播业务,TX UE和RX UE之间需要对SL DRX参数的理解完全一致,因此所有的SL DRX参数取值都需要在两端之间进行统一,比如包括:偏移量(offset),这样TX UE和RX UE才能统一进行收发操作。
对于SIB和pre-configuration两种方式,一般也是区分TX UE或者RX UE的状态,选择其中一种:
(1)当TX UE或者RX UE处于OOC状态,则只能选择pre-configuration方式来获得SL DRX参数,如果pre-configuration信令中没有对应的SL DRX参数,则RX UE只能经常(always)监听,TX UE不受限制;
(2)当TX UE或者RX UE处于Idle、inactive或Connected态,则从SIB消息来获得SL DRX参数,如果SIB消息中没有对应的SL DRX参数,则接收RX UE只能always监听,TX UE不受限制;
(3)从网络侧来看,为了确保组播/广播业务能够正常通信,则pre-configuration消息和不同小区的SIB消息中关于SL DRX参数的配置需要保持一致,这样才能使TX UE和RX UE使用相同的DRX pattern进行收发操作。
实施例二:单播业务的DRX参数。
单播业务因为具有TX UE和RX UE之间一对一的PC5RRC过程,因此可以进行TX UE和RX UE之间的SL DRX参数的相互配置和协商过程,相比于广播/组播业务有更灵活的DRX参数配置方式。
单播业务中,可以由TX UE或者RX UE来决定SL DRX参数,然后将SL DRX参数发送给RX UE或TX UE之后,统一操作。TX UE或者RX UE可以通过以下方式获得SL DR配置参数:
当TX UE/RX UE处于脱网状态,即处于OOC状态,则该TX UE/RX UE从pre-configuration消息获得具体SL DRX参数,由于pre-configuration信令是公共信令,需要针对UE可能发起的所有类型业务进行全面配置,由UE根据当前发起的具体业务选择合适的SL DRX参数,如果没有对应的SL DRX参数,则选择默认SL DRX参数;
当TX UE或RX UE处于Idle或Inactive态,则该TX UE/RX UE从SIB消息获得具体SL DRX参数,同样SIB消息是公共信令,该SIB消息中也需要包含TX UE或RX UE可能发起的所有类型业务进行全面配置,由TX UE或RX UE根据当前发起的具体业务选择合适的SL DRX参数,如果没有对应的SL DRX参数,则选择默认SL DRX参数;
当TX UE或RX UE处于Connected态,则该TX UE或RX UE将自己的SL全部业务信息,例如QoS flow信息,发送给服务基站,由服务基站根据TX UE或RX UE的业务情况决定DRX参数,并通过专有(dedicated)RRC消息发送具体SL DRX参数给TX UE或RX UE,这样配置的SL DRX参数是适合当前业务的DRX参数,TX UE或RX UE无需再进行选择或者决定,一般直接使用即可。
其中,由于pre-configuration消息和SIB消息可以是公共消息,需要配置每个QoS flow或者类似QoS flow组合对应的SL DRX参数集合,例如:
-QoS flow 1,对应的一组SL DRX参数集合,或者不允许配置DRX;
-QoS flow a(a大于1),对应的一组SL DRX参数集合,或者不允许配置DRX;
-QoS flow列表(list)1,其中包含一个或多个QoS flow,对应一组DRX参数集合,或者不允许配置DRX;
-QoS flow list 2,其中包含一个或多个个QoS flow,对应一组DRX参数集合,或者不允许配置DRX;
-或者,QoS flow 1-m,DRX参数集合1-n,每个QoS flow对应于其中一组DRX参数集合或者不对应任何一组DRX参数集合;
-对其中一组DRX参数集合,标记为默认(default);
-显式或者隐式的指示,没有对应SL DRX参数集合的QoS flow,是否 使用default的SL DRX参数,或者不允许使用DRX;
TX UE或RX UE根据自己SL单播业务的QoS flow组合,通过以下方式,获得最终的SL DRX参数:
-最终SL DRX参数,需要满足SL单播业务中每个QoS flow的业务需求;
-如果SL单播业务中,如果有任何一个QoS flow不能配置DRX,则这个SL link不配置SL DRX参数;
-如果有一个QoS flow,没有直接对应的SL DRX参数集合,允许使用default的SL DRX参数集合,则以下步骤中对该QoS flow对应于default的SL DRX参数集合;
-UE对多个QoS flow获得的对应多组SL DRX参数集合,进行如下至少一项操作,获得最终SL DRX参数:
(1)取所有QoS flow对应的SL DRX参数集合中最小的DRX cycle作为最终DRX cycle;
(2)取所有QoS flow对应的SL DRX参数集合中最大的onDuration timer长度或上述最小的DRX cycle对应参数集合中的onDuration timer的长度作为最终onDuration timer的长度;
(3)取所有QoS flow对应的SL DRX参数集合中最大的Inactivity timer长度或上述最小的DRX cycle对应参数集合中的Inactivity timer的长度作为最终Inactivity timer的长度;
(4)取所有QoS flow对应的SL DRX参数集合中最小的HARQ RTT timer长度或上述最小的DRX cycle对应参数集合中的HARQ RTT timer的长度作为最终HARQ RTT timer的长度;
(5)取所有QoS flow对应的SL DRX参数集合中最大的Retransmission timer长度或上述最小的DRX cycle对应SL DRX参数集合中的Retransmission timer的长度作为最终Retransmission timer的长度;
(6)取所有QoS flow对应的SL DRX参数集合中最小的DRX cycle所在的SL DRX参数集合作为最终DRX参数;
(7)UE根据最终DRX cycle长度,随机选择一个offset值;
(8)UE根据最终DRX cycle长度和/或资源池配置,随机选择一个offset值。
在单播业务中,由于TX UE和RX UE之间可以相互通知SL DRX参数,因此根据业务类型决定了SL DRX参数之后,对于offset这个参数,最好采取一定随机选择的机制,避免所有UE选择重叠的DRX pattern,造成碰撞概率升高和资源利用不均匀,即避免所有UE在相同位置发送数据,而空余了很多非激活时间(non-active time)的资源没有UE使用。
TX UE或者RX UE获得了SL DRX参数之后,通过PC5RRC发送给RX UE或TX UE,之后TX UE和RX UE按照配置好的DRX pattern,进行数据收发。
实施例三:配置组播、广播和单播业务的SL DRX参数。
以上两个实施例,分别给出了不同业务类型的SL DRX配置方式。可以看到,SIB消息和pre-configuration消息是不同传输模式中公共的获取SL DRX参数的方式。
本实施例说明SIB消息和pre-configuration消息如何对不同的业务类型进行DRX配置。
第一种方式,在SIB消息和/或pre-configuration消息中,组播/广播业务,和单播业务采取独立方式配置。
例如,组播业务的SL DRX参数配置,广播业务的SL DRX参数配置,单播业务的SL DRX参数配置,可以分别独立进行,当UE要发送或者接收某一种类型的业务,则去对应的SL DRX参数配置集合中寻找合适的SL DRX参数,根据SL DRX参数进行接收或者发送操作;
或者,组播业务和广播业务的SL DRX参数联合配置,和单播业务的SL DRX参数独立配置,这种与上一种方式的差别仅在于组播和广播业务联合一起配置,当UE要发送或者接收某一种组播/广播业务,则去统一的SL DRX参数配置集合中寻找合适的SL DRX参数,从而尊照进行接收或者发送操作。
第二种方式,在SIB消息和/或pre-configuration消息中,组播/广播业务,和单播业务采取联合方式配置。
在这种方式种,由于单播业务是按照QoS flow和SL DRX参数集合的对 应进行配置的,因此要将组播/广播业务也采取相同的结构进行,可以有如下方式:
-对指定的SL DRX参数集合,标记其用于组播或者广播业务;
-按照组播或者广播业务的具体QoS需求,选择对应的SL DRX参数集合;
-按照default SL DRX参数集合,用于组播或者广播业务。
