单播侧链路配置方法、装置及终端
相关申请的交叉引用
本申请主张在2021年7月5日在中国提交的中国专利申请No.202110758772.1的优先权,其全部内容通过引用包含于此。
技术领域
本申请属于通信领域,特别涉及一种单播侧链路配置方法、装置及终端。
背景技术
新空口(New Radio,NR)侧链路(Sidelink,SL,也称直通链路、直接通信链路、副链路等)单播的直接通信接口(PC5)非连续接收(Discontinuous Reception,DRX)参数可以通过不同的业务所需的服务质量(Quality of Service,QoS)配置文件(Profile)经过用户设备(User Equipment,UE,也称终端)间在接入层(Access Stratum,AS)的信息交互来进行配置。即,接收终端(Receive UE or Peer UE,Rx UE,也称接收端)发送辅助信息(Assistance Information)给发送终端(Transmit UE,Tx UE,也称发送端),而Tx UE根据Rx UE的信息和自己业务所需的QoS,最后判断决定单播的PC5 DRX。
一般情况下,Tx UE可以通过所需的QoS Profile或PC5 QoS ID(PQI)来配置特殊(Specific)PC5 DRX的参数。车到万物(vehicle to everything,V2X)层将这些信息提供给AS层,AS层通过单播间UE信息交互磋商,由Tx UE考虑Rx UE提供的辅助信息(Assistance Information),并结合业务所需的QoS Profile信息,决定最终的PC5 DRX配置。因此在AS层Tx UE能够根据自己的业务性质/特点,同时结合Rx UE提供的辅助信息有效地配置PC5 DRX参数。
当Rx UE没有实施DRX的时候,Rx UE不需要Tx UE的QoS Profile信息来接收数据包,但是,当Rx UE实施DRX的时候,由于DRX参数是根据Tx UE的QoS Profile信息来决定的,但是在业务初始阶段,即单播UE间还没有建立单播侧链路之前,单播的Rx UE是无法获取Tx UE的QoS Profile 信息的,在没有相关的Tx UE的QoS Profile信息的情况下,Rx UE无法确定DRX参数,这就意味着Rx UE在单播侧链路以后无法进入单播节能模式。

具体实施方式
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描述,显然,所描述的实施例是本申请一部分实施例,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所获得的所有其他实施例,都属于本申请保护的范围。
本申请的说明书和权利要求书中的术语“第一”、“第二”等是用于区别类似的对象,而不用于描述特定的顺序或先后次序。应该理解这样使用的术语在适当情况下可以互换,以便本申请的实施例能够以除了在这里图示或描述的那些以外的顺序实施,且“第一”、“第二”所区别的对象通常为一类,并不限定对象的个数,例如第一对象可以是一个,也可以是多个。此外,说明书以及权利要求中“和/或”表示所连接对象的至少其中之一,字符“/”一般表示前后关联对象是一种“或”的关系。
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。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,但是这些技术也可应用于NR系统应用以外的应用,如第6代(6th Generation,6G)通信系统。
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单播侧链路配置方法、装置及终端进行详细地说明。
如图1所示,本申请实施例提供一种单播侧链路配置方法,包括:
步骤101,在单播侧链路建立过程中,被配置非连续接收DRX模式的接收端接收发送端发送的第一无线资源控制RRC参数配置信息和第一DRX的 参数配置信息;
需要说明的是,可选地,该第一RRC参数配置信息在本申请实施例中指的是无线通信所需的PC5-RRC典型参数配置信息(PC5-RRC NORMAL参数配置信息)。
需要说明的是,针对于PC5 DRX,本申请中主要包括:默认PC5 DRX(Default PC5 DRX)和特殊PC5 DRX(Specific PC5 DRX),当然还存在其他类型的DRX,在单播侧链路建立之前,终端通常使用的是默认PC5 DRX,而默认PC5 DRX参数是预配置的。在本申请实施例中在单播链路建立过程中主要进行Specific PC5 DRX的配置,该Specific PC5 DRX只在单播链路通信过程中使用;也就是说,本申请实施例中所说的第一DRX的参数配置信息可以指的是Specific PC5 DRX的参数配置信息。
步骤102,在第一RRC参数配置失败的情况下,所述接收端接收所述发送端重新发送的第一RRC参数配置信息,和/或,在第一DRX的参数配置失败的情况下,所述接收端接收所述发送端重新发送的第一DRX的参数配置信息。
这里需要说明的是,本申请实施例中,在配置过程中,哪一个参数配置失败则重新配置哪一个参数,无需进行所有参数的重新配置,能够提高配置效率,节省单播链路建立过程中的信令开销。
这里需要说明的是,在终端间进行业务时,发送业务数据包的一方称为发送终端(Tx UE,也可以称为发送端),接收业务数据包的一方称为接收终端(Rx UE,也可以称为接收端)。
一般来说,PC5-RRC NORMAL参数配置信息数据量远远大于Specific PC5 DRX的参数配置信息的数据量,而且Rx UE对PC5-RRC NORMAL参数的配置要求基本依赖于Tx UE。在配置PC5-RRC NORMAL参数过程中,Rx UE不发送辅助信息(Assistance Information),而在配置Specific PC5 DRX的参数过程中,Rx UE会发送辅助信息。因此,PC5-RRC NORMAL参数的配置成功率要远远大于Specific PC5 DRX的参数。
为了提高配置效率,本申请提出以下三种配置方式来配置PC5-RRC NORMAL参数和Specific PC5 DRX的参数。
配置方式一、Tx UE使用合并的配置方式
此种情况下,步骤101的具体实现方式为:
在单播侧链路建立过程中,所述接收端接收所述发送端通过侧链路RRC配置信息同时发送的第一RRC参数配置信息和第一DRX的参数配置信息。
也就是说,在单播侧链路建立过程中,所述接收端接收所述发送端通过一个侧链路RRC配置(RRCReconfigurationSidelink)信息同时发送的PC5-RRC典型参数配置信息和第一DRX的参数配置信息。
在所述PC5-RRC典型参数和所述第一DRX的参数均配置成功的情况下,所述接收端发送侧链路无线资源控制配置完成(RRCReconfigurationCompleteSidelink)信息给所述发送端;
在至少所述PC5-RRC典型参数配置失败的情况下,所述接收端发送侧链路RRC配置失败(RRCReconfigurationFailureSidelink)信息给所述发送端,发送端在接收到侧链路RRC配置失败信息后,重新通过侧链路RRC配置信息发送第一RRC参数配置信息和第一DRX的参数配置信息给接收端;
在所述PC5-RRC典型参数配置成功、所述第一DRX的参数配置失败的情况下,所述接收端发送辅助信息给所述发送端,所述辅助信息用于指示所述发送端重新发送所述第一DRX的参数配置信息。
也就是说,Tx UE通过一条RRCReconfigurationSidelink为Rx UE同时配置PC5-RRC NORMAL参数和Specific PC5 DRX的参数,只有当Rx UE确认PC5-RRC NORMAL参数和Specific PC5 DRX的参数都配置成功,Rx UE通过侧链路RRC配置完成(RRCReconfigurationCompleteSidelink)信息发送成功确认信息;只要PC5-RRC的典型参数配置失败,则Rx UE将发送RRCReconfigurationFailureSidelink确认配置失败,Rx UE需要重新配置PC5-RRC NORMAL参数和Specific PC5 DRX的参数,即Rx UE通过RRCReconfigurationSidelink重新发送PC5-RRC NORMAL参数配置信息和Specific PC5 DRX的参数配置信息;当只有Specific PC5 DRX的参数配置失败的情况下,Rx UE将不发送RRCReconfigurationFailureSidelink,而是通过终端侧链路辅助信息(UEAssistanceInformationSidelink)发送辅助信息给Tx UE(此种方式可以认为是隐式指示方式,即只要发送了辅助信息就隐式指示 Specific PC5 DRX的参数配置失败),要求Tx UE重新配置Specific PC5 DRX的参数,Tx UE在接收到该辅助信息后,确定是Specific PC5 DRX的参数配置失败,重新发送Specific PC5 DRX的参数配置信息给Rx UE。
配置方式二、Tx UE使用并行的配置方式
此种情况下,步骤101的具体实现方式为:
在单播侧链路建立过程中,所述接收端接收所述发送端通过侧链路RRC配置信息同时发送的第一RRC参数配置信息和第一DRX的参数配置信息。
也就是说,在单播侧链路建立过程中,所述接收端接收所述发送端通过一个侧链路RRC配置信息同时配置的PC5-RRC典型参数配置信息和第一DRX的参数配置信息。
接收端在第一RRC参数配置失败的情况下,发送第一侧链路RRC配置失败信息给所述发送端;发送端在接收到第一侧链路RRC配置失败信息后,重新发送第一RRC参数配置信息,接收端只需重新接收该第一RRC参数配置信息即可。
接收端在第一DRX的参数配置失败的情况下,发送第二侧链路RRC配置失败信息或辅助信息给所述发送端;发送端在接收到第二侧链路RRC配置失败信息或辅助信息后,重新发送第一DRX的参数配置信息,接收端只需重新接收该第一DRX的参数配置信息即可。
接收端在第一RRC参数配置成功的情况下,发送第一侧链路RRC配置完成信息给所述发送端;在第一DRX的参数配置成功的情况下,发送第二侧链路RRC配置完成信息给所述发送端。
需要说明的是,此种情况下,发送端通过一条侧链路RRC配置信息同时发送PC5-RRC典型参数配置信息和Specific PC5 DRX的参数配置信息给接收端,当发送端接收到第一侧链路RRC配置失败信息后,需要重新发送PC5-RRC NORMAL参数配置信息给接收端,接收端在新配置的PC5-RRC NORMAL参数配置成功的情况下,发送第一侧链路RRC配置完成信息给所述发送端,否则,发送第一侧链路RRC配置失败信息给所述发送端,直到PC5-RRC NORMAL参数配置成功为止;当发送端接收到第二侧链路RRC配置失败信息后,需要重新发送Specific PC5 DRX的参数配置信息给接收端, 接收端在新配置的Specific PC5 DRX的参数配置成功的情况下,发送第二侧链路RRC配置完成信息给所述发送端,否则,发送第二侧链路RRC配置失败信息给所述发送端,直到Specific PC5 DRX的参数配置成功为止。
需要说明的是,此种情况指的是Tx UE为Rx UE同时配置PC5-RRC典型参数和Specific PC5 DRX的参数,但是Rx UE独立确认每个配置是否成功。
例如,Tx UE可以通过使用RRCReconfigurationSidelink同时配置PC5-RRC NORMAL参数和Specific PC5 DRX的参数,Rx UE对PC5-RRC NORMAL参数和Specific PC5 DRX的参数使用不同的RRCReconfigurationCompleteSidelink和不同的RRCReconfigurationFailureSidelink发送反馈信息,以便Tx UE可以为PC5-RRC NORMAL参数和Specific PC5 DRX的参数单独进行配置。例如,若PC5-RRC NORMAL参数配置成功,Rx UE通过RRCReconfigurationCompleteSidelink1为PC5-RRC NORMAL参数发送确认信息,否则,Rx UE将发送RRCReconfigurationFailureSidelink1,以请求进行PC5-RRC NORMAL参数的重新配置;若Specific PC5 DRX的参数配置成功,Rx UE通过RRCReconfigurationCompleteSidelink2为Specific PC5 DRX的参数发送确认信息,否则Rx UE将发送RRCReconfigurationFailureSidelink2,以请求进行Specific PC5 DRX的参数的重新配置。
需要说明的是,因针对PC5-RRC NORMAL参数和Specific PC5 DRX的参数配置,当采用不同的侧链路RRC配置失败信息进行失败反馈时,此种方式可以被考虑显式指示方式。
配置方式三、Tx UE使用串行的配置方式
此种情况下,步骤101的具体实现方式为:
在单播侧链路建立过程中,所述接收端接收所述发送端通过侧链路RRC配置信息发送的第一目标参数配置信息;
在第一目标参数配置成功的情况下,所述接收端发送侧链路RRC配置完成信息给所述发送端;
所述接收端接收所述发送端通过侧链路RRC配置信息发送的第二目标 参数配置信息;
其中,所述第一目标参数配置信息为第一RRC参数配置信息和第一DRX的参数配置信息中的一者,所述第二目标参数配置信息为第一RRC参数配置信息和第一DRX的参数配置信息中的另一者。
也就是说,此种情况指的是先进行第一目标参数的配置,在第一目标参数配置失败的情况下,接收端发送侧链路RRC配置失败信息给所述发送端,发送端在接收到侧链路RRC配置失败信息后,重新发送第一目标参数配置信息;只有当接收端发送侧链路RRC配置完成信息之后,发送端才会进行第二目标参数配置信息的发送,在第二目标参数配置成功的情况下,所述接收端发送侧链路无线资源控制配置完成信息给所述发送端;在第二目标参数配置失败的情况下,所述接收端发送侧链路无线资源控制配置失败信息给所述发送端,发送端在接收到侧链路RRC配置失败信息后,重新发送第二目标参数配置信息;
这里需要说明的是,对于第一DRX的参数配置信息,若第一DRX的参数配置失败,则接收端需要反馈辅助信息用于进行第一DRX的参数的重配,因此,当第一目标参数配置信息或第二目标参数配置信息为第一DRX的参数配置信息的情况下,若第一DRX的参数配置失败,则接收端反馈的可以是侧链路RRC配置失败信息,接收端也可以反馈辅助信息。
需要说明的是,此种方式是Tx UE为Rx UE独立配置PC5-RRC NORMAL参数和Specific PC5 DRX的参数。例如,Tx UE通过RRCReconfigurationSidelink首先为Rx UE配置PC5-RRC NORMAL参数,如果Rx UE认为PC5-RRC NORMAL参数配置成功,Rx UE将通过RRCReconfigurationCompleteSidelink发送确认信息;然后,Tx UE通过RRCReconfigurationSidelink再为Rx UE配置Specific PC5 DRX的参数,如果Rx UE并不认可Tx UE配置的Specific PC5 DRX的参数,Rx UE将向Tx UE发送通过UEAssistanceInformationSidelink发送辅助信息,通过drx-PreferenceConfigSidelink告知Tx UE自己的PC5 DRX配置的偏好;然后,Tx UE根据Rx UE提供的辅助信息和业务要求的QoS信息,为Rx UE重新配置Specific PC5 DRX的参数。
在单播UE间配置PC5-RRC NORMAL参数和Specific PC5 DRX的参数过程中,Rx UE只需要使用相同的RRCReconfigurationCompleteSidelink为Rx UE发送确认信息即可。
值得注意的是,由于配置的PC5-RRC NORMAL参数的数据量远远大于Specific PC5 DRX的参数的数据量,而且Rx UE对PC5-RRC NORMAL参数的配置要求基本依赖于Tx UE,PC5-RRC NORMAL参数的配置成功率要远远大于Specific PC5 DRX,因此使用独立配置方式,能够提高系统配置的效率。
需要说明的是,对于PC5-RRC NORMAL参数和Specific PC5 DRX的参数的配置的顺序本申请中并不进行限定,Tx UE可以先为Rx UE配置Specific PC5 DRX的参数,然后再配置PC5-RRC NORMAL参数,Tx UE也可以先为Rx UE配置PC5-RRC NORMAL参数,然后再配置Specific PC5 DRX的参数。
因此,在Specific PC5 DRX的参数配置之前,必须在Default PC5 DRX的On-duration或Default PC5 DRX的On-duration之后的延长时间(偏移时间(Time Offset)或扩展时间(Extension Time))内发送信息,这是因为针对Specific PC5 DRX配置,只有在Rx UE发送和Tx UE接收到最后一个RRCReconfigurationCompleteSidelink时,才能算完成Specific PC5 DRX配置。
由于业务变化的原因,PC5 QoS流(PC5 QoS Flow)会被增加,修改或删除。如果PC5 QoS Flow(s)发生变化,Specific PC5 DRX也应该相应地被更新。单播侧链路更新是在每个UE的V2X层决定。一旦UE决定更新单播侧链路,V2X层会向AS层提供有关单播侧链路更新的信息,最后,AS层执行单播侧链路的更新。
因更新可以是接收端发起也可以是发送端发起,下面对这两种方式进行说明如下。
一、发送端发起
此种情况下的具体地实现方式为:所述接收端接收链路更新请求,所述链路更新请求用于指示进行第一DRX的参数配置信息的更新;
在向所述发送端反馈侧链路无线资源控制配置完成信息后,所述接收端更新所述第一DRX的参数配置信息。
需要说明的是,对于发送端发送链路更新请求给所述接收端,在接收到所述接收端反馈的侧链路无线资源控制配置完成信息后,所述发送端更新所述第一DRX的参数配置信息。
二、接收端发起
此种情况下的具体地实现方式为:所述接收端发送链路更新请求,所述链路更新请求用于指示进行第一DRX的参数配置信息的更新;
在接收到所述发送端反馈的侧链路无线资源控制配置完成信息后,所述接收端更新第一DRX的参数配置信息。
需要说明的是,对于接收端发送链路更新请求,发送端接收所述接收端发送的链路更新请求,向接收端反馈侧链路无线资源控制配置完成信息后,发送端更新第一DRX的参数配置信息。
综上可知,更新单播侧链路的具体过程是:当单播的一方UE-2希望更新单播侧链路时,该UE会向另一方UE-1发送链路修改请求(Link Modification Request)要求。当UE-1收到该侧链路更新要求并认同侧链路更新的情况下,UE-1会向UE-2发送链路修改接受(Link Modification Accept)信息。
在侧链路更新过程中,单播UE间的通信还是根据现有的Specific PC5DRX进行,只有在侧链路更新完毕以后,单播UE间的通信将切换到新的Specific PC5 DRX配置,即只有在UE-1发送和UE-2接收到RRCReconfigurationCompleteSidelink时,才能算完成更新Specific PC5 DRX的参数,单播UE间的通信可以使用新的Specific PC5 DRX的参数。这样根据不同QoS配置的不同Specific PC5 DRX对齐性问题得到了很好的解决。利用发送和接收到RRCReconfigurationCompleteSidelink的时间点来作为Specific PC5 DRX的参数配置切换点能更加灵活并且有效对齐单播Specific PC5 DRX配置。
下面对本申请的几种应用情况进行举例说明如下。
具体应用情况一、
如图2所示,在合并配置方式中,可选地,在时间t30,Tx UE通过RRCReconfigurationSidelink为Rx UE配置PC5-RRC NORMAL和Specific PC5 DRX参数(即PC5-RRC NORMAL参数和Specific PC5 DRX的参数)。 由于PC5-RRC NORMAL参数或Specific PC5 DRX的参数配置失败,在时间t31,Rx UE通过RRCReconfigurationFailureSidelink发送配置失败信息。
可选地,在时间t32,Tx UE通过RRCReconfigurationSidelink为Rx UE配置PC5-RRC NORMAL和Specific PC5 DRX参数,由于PC5-RRC NORMAL和Specific PC5 DRX参数配置成功,在时间t33,Rx UE通过RRCReconfigurationCompleteSidelink发送配置成功信息。
可选地,在时间t34,Tx UE通过RRCReconfigurationSidelink为Rx UE配置PC5-RRC NORMAL和Specific PC5 DRX参数,由于PC5-RRC NORMAL参数配置成功,而Specific PC5 DRX的参数配置失败,在时间t35,Rx UE没有通过RRCReconfigurationFailureSidelink向Tx UE发送配置失败信息,而通过UEAssistanceInformationSidelink向Tx UE发送相关的辅助信息,Rx UE发送辅助信息给Tx UE,意味着Rx UE用隐式方式告知Tx UE,PC5-RRC NORMAL参数配置成功,而Specific PC5 DRX的参数配置失败。在时间t36,Tx UE通过RRCReconfigurationSidelink为Rx UE重新配置Specific PC5 DRX的参数。在时间t37,Rx UE通过RRCReconfigurationCompleteSidelink发送相应配置成功信息。
具体应用情况二、
如图3所示,在并行配置方式中,在时间t40,Tx UE通过RRCReconfigurationSidelink为Rx UE配置PC5-RRC NORMAL和Specific PC5 DRX参数。由于PC5-RRC NORMAL参数配置成功,而Specific PC5 DRX的参数配置失败,在时间t41,Rx UE通过RRCReconfigurationCompleteSidelink1发送PC5-RRC NORMAL参数配置成功信息。在时间t42,Rx UE通过RRCReconfigurationFailureSidelink2发送Specific PC5 DRX配置失败信息。
在时间t43,Rx UE通过UEAssistanceInformationSidelink向Tx UE发送相关的辅助信息。在时间t44,Tx UE考虑Rx UE的辅助信息,并根据业务的QoS要求,Tx UE通过RRCReconfigurationSidelink为Rx UE重新配置Specific PC5 DRX的参数。在时间t45,Rx UE通过RRCReconfigurationCompleteSidelink2发送配置成功信息。
并行配置方法意味着,Rx UE是通过显式方式告知Tx UE被配置的参数是成功或失败。
可选地,在时间t42,Rx UE可以不发送RRCReconfigurationFailureSidelink2,而直接通过UEAssistanceInformationSidelink在时间t43向Tx UE发送辅助信息。即,Rx UE用隐式方式告知Tx UE,Specific PC5 DRX的参数配置失败,并要求Tx UE考虑辅助信息,重新配置Specific PC5 DRX的参数。
具体应用情况三、
如图4所示,在串行配置方式中,在时间t50,首先,Tx UE通过RRCReconfigurationSidelink为Rx UE配置PC5-RRC NORMAL参数。在时间t51,Rx UE通过RRCReconfigurationCompleteSidelink发送配置成功信息。
在时间t52,Tx UE通过RRCReconfigurationSidelink为Rx UE配置Specific PC5 DRX的参数,由于Tx UE配置的Specific PC5 DRX的参数和Rx UE希望的不相符合,在时间t53,Rx UE通过RRCReconfigurationFailureSidelink发送配置失败信息。而后,在时间t54,Rx UE通过UEAssistanceInformationSidelink向Tx UE发送相关的辅助信息。在时间t55,Tx UE通过RRCReconfigurationSidelink为Rx UE重新配置Specific PC5 DRX的参数。在时间t56,Rx UE通过RRCReconfigurationCompleteSidelink发送相应配置成功信息。
在时间t53,Rx UE可以不发送RRCReconfigurationFailureSidelink,而直接通过UEAssistanceInformationSidelink在时间t54向Tx UE发送辅助信息。即,Rx UE用隐式方式告知Tx UE,Specific PC5 DRX的参数配置失败,并要求Tx UE考虑辅助信息,重新配置Specific PC5 DRX的参数。
具体应用情况四、
此种应用情况主要是说明由于单播业务变化的原因,Tx UE更新PC5 QoS Flow,从而使Specific PC5 DRX被重新配置。
如图5所示,在时间t18以前,Tx UE应用层要求QoS1相关的单播业务,因此Tx UE使用Specific PC5 DRX1配置,向Rx UE发送数据包。在时间t18,Tx UE应用层改变单播业务,决定提供QoS2相关的单播业务,同时应用层 通过V2X层通知AS层,更新PC5-RRC NORMAL和Specific PC5 DRX。
值得注意的是,本实施例中,QoS1要求的PDB要大于QoS2要求的PDB,因此,针对QoS2业务要求的Specific PC5 DRX周期也相应的比QoS1业务要求的Specific PC5 DRX周期短。
在时间t19,Tx UE在Specific PC5 DRX1相关的On-duration中发送Link Modification Request给Rx UE,并在时间t22,Rx UE发送Link Modification Accept给Tx UE。即,更新PC5-RRC NORMAL和Specific PC5 DRX的过程是在时间t19和时间t22之间进行的,共使用了两个Specific PC5 DRX1相关的On-duration。
在时间t18,应用层通过AS层要求更新PC5-RRC NORMAL和Specific PC5 DRX之后,QoS2相关的数据包在时间t20已经到达AS层,由于新的Specific PC5 DRX2还没有配置完毕,在时间t22以前,Tx UE和Rx UE间的通信必须使用Specific PC5 DRX1配置。因此在时间t21,Tx UE使用Specific PC5 DRX1相关联的On-duration发送在时间t20到达的新数据包。
在时间t22之后,单播UE间已经更新了PC5-RRC NORMAL和Specific PC5 DRX配置,因此在时间t23,当QoS2相关的数据包到达AS层,Tx UE在Specific PC5 DRX2相关联的On-duration中的时间t24,发送QoS2相关的数据包。之后,Tx UE利用合并Default PC5 DRX On-duration和Specific PC5DRX2On-duration作为PC5-DRX激活时间(Active Time),发送QoS2相关的数据包。
利用在时间t22发送和接收到RRCReconfigurationCompleteSidelink的时间点来作为Specific PC5 DRX的参数配置切换点是配置灵活性更高,并且对齐性更好。
综上可知,本申请实施例可以达到如下有益效果:
在为单播UE配置Specific PC5 DRX的参数时,通过区分PC5-RRC NORMAL参数和PC5-RRC DRX的参数,使得系统整体的PC5-RRC NORMAL参数配置更加灵活有效;
在单播Specific PC5 DRX的参数配置更新过程中,本申请实施例解决了Specific PC5 DRX的参数配置对齐性问题,寻找到了利用发送和接收到 RRCReconfigurationCompleteSidelink的时间点来作为Specific PC5 DRX的参数配置切换,使得单播UE间的Specific PC5 DRX的配置使用更加灵活并且对齐性更好。
