为便于理解本申请的实施例,首先对本申请中涉及到的术语做简单说明。
1、侧行链路中的广播、组播通信方式
广播或组播是指一个发送设备发送的广播或组播数据,能够被一个或多个终端设备接 收到。例如,预先定义业务数据在PC5接口上传输时所使用的目的层2标识(Destination Layer-2ID)。当发送设备有该广播业务数据发送时,可以在媒体接入控制(mediaaccesscontrolprotocol,MAC)层和/或物理层(physical,PHY)层填充该广播业务对应的目的标识(Destination ID)。对该广播业务感兴趣的终端设备可以在PHY层监听是否有标识了该广播业务对应的目的层1标识(Destination Layer-1 ID)的信息,或者在MAC层判断是否收到标识了该广播业务对应的目的层2标识(Destination Layer-2 ID)的信息,并进行接收、解析,但本申请不限于此。
2、侧行链路中的单播通信方式
单播是终端设备一对一的通信方式,发送设备通过目的标识指示其发送的单播数据的接收设备,接收设备根据单播数据的目的标识或者目的标识和源标识确定该单播数据是否是发送给自己的单播数据,以及根据单播数据的源地址确定该单播数据是由哪个设备发送的。可选地,两个终端设备可以通过信令交互建立该两个设备之间的单播连接,单播连接建立完成后可以进行单播通信。
3、侧行链路传输模式1(mode1)
侧行链路mode1是指终端设备根据网络设备发送的侧行链路调度授权(sidelinkgrant)确定用于发送侧行链路数据的资源。该侧行链路调度授权用于授权该终端设备专用的发送侧行链路数据的资源。例如,终端设备在发送侧行链路前,向网络设备上报缓存状态报告bufferstatus reports,BSR)以通知网络设备待发送的数据量,网络设备根据终端设备上报的数据量为其授权相应资源。
4、侧行链路传输模式2(mode2)
侧行链路mode2是指网络设备预先分配用于侧行链路的资源池,例如终端设备可以通过预配置、系统消息广播、专用信令等获取该用于侧行链路的资源池,多个终端设备可以在该用于侧行链路的资源池中竞争资源,在竞争到资源的情况下,终端设备可以在该竞争到的资源上发送侧行链路的数据。例如,终端设备根据测量该用于侧行链路的资源池中的时频资源是否被占用、来选择未被占用的资源进行传输,但本申请不限于此。
5、持续定时器(onduration timer)
对于SL DRX,持续定时器是指一个SL DRX周期开始的一段时间(duration)。在该定时器运行期间,接收UE处于激活时间,或者,需监听SCI。每个SL连接或目的地(destination)对应的SL DRX配置可对应一个持续定时器;
6、非激活定时器(inactivity timer)
对于SL DRX,非激活定时器是指收到指示新传的SCI后的一段时间。在该定时器运行期间,接收UE处于激活时间,或者,需监听SCI。每个SL连接或目的地(destination)对应的SL DRX配置可对应一个非激活定时器
7、重传定时器(retransmission timer)
对于SL DRX,重传定时器是指直至收到SL重传的最长时间。每个SL进程对应一个重传定时器。
8、混合自动重传请求往返时间定时器(HARQ RTT timer)
对于SL DRX,混合自动重传请求往返时间定时器是指MAC实体期望收到SL HARQ重传之前的最长时间。每个SL进程对应一个混合自动重传请求往返时间定时器。
在网络设备与终端设备交互的通信系统中,网络设备可以向终端设备发送物理下行控制信道(physical downlink control channel,PDCCH)。PDCCH主要用于传输下行控制信息(downlink control information,DCI),或者说用于承载DCI,包括用于下行和上行数据传输的调度信息、上行功率控制信息、时隙格式信息等。
类似地,在侧行链路通信中,即在终端设备与终端设备交互的通信系统中,发送端(transmitter,TX)也可以向接收端(receiver,RX)发送SL信息,该SL信息中可以包括侧行链路控制信息(sidelink control information,SCI),该SCI可以用于接收端对接收的SL信息中的SL数据进行解码,因此,接收端将接收SCI。然而,由于接收端不清楚发送端发送SL信息的时间,接收端需要监听SCI,若接收端一直处于监听状态将显著增加接收端功耗。因此,可以在终端设备中执行SLDRX操作,从而使得接收端仅需在部分时间监听SCI,从而降低接收端终端设备的功耗。
在SL通信中,终端设备可以执行SLDRX操作,该SL DRX操作对应的SL DRX配置可以由网络设备进行配置,例如,网络设备向终端设备发送包括SL DRX配置的信息。终端设备可以确定接受或拒绝该SL DRX配置,然而对于终端设备如何确定接受或拒绝SL DRX配置的判断方式并没有进一步的规定,即SL DRX配置的配置方式不够完善。
此外,对于网络设备调度终端设备以实现终端设备的SL通信系统中,终端设备在与网络设备通信的空口上,可以执行DRX操作,例如Uu DRX,并且终端设备在与其他终端设备通信的空口上,也可以执行DRX操作,例如SL DRX。然而Uu DRX与SL DRX的不对齐或不一致可能会导致通信资源的浪费。例如,当作为发送端的终端设备在与网络设备通信的空口上没有收到网络设备配置的用于SL连接的混合自动重传请求(hybrid automatic repeat request,HARQ)反馈资源时,即网络设备没有为作为发送端的终端设备配置用于SL连接的HARQ反馈资源时,网络设备将无法确定发送端对应的接收端是否成功解码数据,网络设备可能会继续向发送端调度资源(例如用于发送端向接收端发送信息的资源),然而接收端可能处于睡眠状态,从而可能会造成发送端接收网络设备调度的资源后,将该调度的资源丢弃,导致资源的浪费;或发送端接收网络设备调度的资源后,用于发送其他进程(process)的数据,由于接收端处于睡眠状态,导致丢包。
因此,本申请实施例提供了无线通信的方法,一方面,能够完善通信设备确定接受或拒绝SL DRX配置的准则,另一方面能够避免因网络设备不确定RX的active time导致的通信资源的浪费或RX丢包。
应理解,通信设备可以为终端设备,也可以为未来演进的终端设备,还可以为网络设备,本申请对此不作限定。
应理解,本申请实施例中对具体场景的描述仅为举例,本申请实施例提供的方法除了可以应用于上述描述的应用场景外,同样适用于存在类似问题的应用场景。
还应理解,在本申请实施例提供的无线通信的方法中,有些方法可以应用于通信设备的DRX相关机制中的部分流程,有些方法可以应用于通信设备的DRX相关机制中的任意一个或多个流程。还应理解,本申请实施例提供的无线通信的方法可以相互结合使用,例如,通信设备的DRX相关机制中的某一流程使用一种方法,而另一流程使用另一种方法,或者,还可以是通信设备的DRX相关机制中的某一流程既使用一种方法又使用另一种方法。
还应理解,应用于通信设备的DRX相关机制可能会随着技术的演进而发生变化,本申请提供的方法还适用于未来演进的DRX相关机制。
下面结合附图详细说明本申请实施例提供的无线通信的方法。

因此,通信设备可以在接收到SL DRX配置信息后,可以根据自身情况,或者说自身的状态,即状态信息,确定接收或拒绝该SL DRX配置信息,从而完善了通信设备确定接受或拒绝SL DRX配置的机制。
可选的,第一通信设备的状态信息可以具体包括以下至少一项:第一通信设备的第二SL连接的SL DRX配置信息、第一通信设备建议或期望的SL DRX配置信息、第一通信设备的发送资源配置信息、第一通信设备的节能需求信息、第一通信设备的电量信息。

还应理解,第一通信设备的发送资源配置信息可以包括第一通信设备的发送资源池配置信息。
一种可能的实现方式中,第一通信设备根据第一SL DRX配置信息以及第一通信设备的状态信息,确定接受或拒绝该第一SL DRX配置信息,可以包括:第一通信设备根据第一SL DRX配置信息与第一通信设备的第二SL连接的SL DRX配置信息不匹配,确定拒绝该第一SL DRX配置信息。
在本申请实施例中,第一SL DRX配置信息与第一通信设备的第二SL连接的SL DRX配置信息不匹配,可以包括:第一SL DRX配置信息对应的激活时间与第二SL连接的SL DRX配置信息对应的激活时间的重叠信息满足某个条件,例如,第一SL DRX配置信息对应的第一激活时间与第二SL连接的SL DRX配置信息对应的第二激活时间的重叠度小于或等于第一门限值,本申请不限于此。应理解,第一激活时间和第二激活时间可以是在某个时间段内,第一通信设备可以处于唤醒状态(wake up)的时间。还应理解,第一激活时间与第二激活时间的重叠度可以理解为,第一激活时间和第二激活时间的重叠时长, 或者还可以理解为第一激活时间占第二激活时间的比率,或者还可理解为第一激活时间与第二激活时间重叠的时长占第三时间的比率,其中第三时间为第一激活时间与第二激活时间的并集。以上对于“第一激活时间与第二激活时间的重叠度”的理解,也适用于本申请中其他地方任意“两个激活时间(如第k激活时间与第j激活时间)的重叠度”的理解。

在本申请实施例中,第一SL DRX配置信息与第一通信设备的节能需求信息不匹配,可以包括:第一SL DRX配置信息与对应的第一节能增益小于或等于节能需求信息对应的第二节能增益,或第一SL DRX配置信息对应的第一节能增益与节能需求信息对应的第二节能增益的比值小于或等于第三门限值,或第一SL DRX配置信息对应的第一节能增益小于或等于第四门限值。
应理解,具体地,在本申请实施例中,以第一通信设备为接收端RX,第二通信设备为发送端TX为例,当RX的当前节能需求较强,但是TX向RX配置的第一SL DRX配置信息对应的持续定时器(onduration timer)较长,或DRX周期(DRX cycle)较短时,第一通信设备可以确定第一SL DRX配置信息与第一通信设备的节能需求信息不匹配。例如,可以将RX从TX接收到的第一SL DRX配置信息对应的节能增益A与RX当前要求的节能增益B进行比较,当节能增益A小于节能增益B或节能增益A未达到节能增益B的某个百分比值,则第一通信设备可以确定拒绝第一SL DRX配置信息。
可选的,节能增益A的计算可以满足公式1-onduration/DRX cycle,节能增益B可以由第一通信设备确定。其中,onduration表示在一个DRX周期中持续定时器(onduration timer)的运行时长,DRX cycle表示DRX的周期。
可选的,本申请中的“节能增益”可替换为“睡眠时间占比”,或“最大睡眠时间占比”。

在本申请实施例中,第一SL DRX配置信息以及第一通信设备建议或期望的SL DRX配置信息不匹配,包括:第一SL DRX配置信息对应的激活时间与第一通信设备建议或期望的SL DRX配置信息对应的激活时间的重叠信息满足某个条件,例如,第一SL DRX配置信息对应的第一激活时间与第一通信设备建议或期望的SL DRX配置信息对应的第三激活时间的重叠度小于或等于第八门限值,本申请不限于此。

S203,第一通信设备发送第二信息,第二信息用于指示拒绝第一SL DRX配置,或第二信息用于指示第一SL DRX配置失败,相应的,第二通信设备接收该第二信息。
因此,通过通信设备在确定拒绝SL DRX配置时,向对侧通信设备发送信息来指示对侧通信设备SL DRX机制的配置情况,对侧通信设备获知后可以对后续的SL DRX配置进行决策、确定是否根据该SL DRX配置进行调度等操作,从而完善了SL DRX的配置机制。
进一步的,TX为RX配置SL DRX机制的同时,还可以配置其他机制,因此还需要对TX为RX配置SL DRX机制以及其他机制的方式进行优化。例如,下述本申请实施例提供的无线通信的方法300。

S402,第二通信设备根据该第一HARQ进程对应的DRX机制的定时器的运行情况,确定网络设备不发送或不调度第一目的地或第一SL连接的资源配置信息,第一目的地或第一SL连接为该第一HARQ进程对应的目的地或SL连接,相应的,网络设备根据该第一HARQ进程对应的DRX的定时器的运行情况,确定不发送或不调度该第一HARQ进程对应的SL连接的资源配置信息。
具体地,在本申请实施例中,第二通信设备确定网络设备不发送或不调度第一目的地或第一SL连接的资源配置信息,可以替换为,第二通信设备确定不期望网络设备发送或调度第一目的地或第一SL连接的资源配置信息。
应理解,第一目的地的资源配置信息可以包括第一目的通信设备的资源配置信息,或者可以包括第一目的地址标识对应的资源配置信息。
因此,通过当通信设备确定在与网络设备通信的空口上,无反馈资源配置时,规定网络设备不再发送或不再调度相关资源配置,从而避免了网络设备继续调度资源,通信设备将资源浪费的情况发生,提高了资源的利用率。
在本申请实施例中,网络设备不发送或不调度第一目的地或第一SL连接的资源配置信息,包括:网络设备不发送或不调度该第一目的地或第一SL连接对应的除第一HARQ进程之外的其他HARQ进程的新传或重传;和/或,网络设备不发送或不调度该第一目的地或第一SL连接对应的第一HARQ进程的新传。
一种可能的实现方式中,可以根据第一HARQ进程对应的DRX的重传定时器retransmission timer、持续定时器on duration timer和非激活定时器inactivity timer中至少一种定时器的运行情况,确定不发送或不调度该第一目的地或第一SL连接的资源配置信息。例如,在满足以下至少一项时,确定网络设备不发送或不调度该第一目的地或第一SL连接的资源配置信息:在第二通信设备的第一接口的DRX上仅有该第一HARQ进程对应的重传定时器retransmission timer在运行;在第二通信设备的第一接口的DRX上该第一HARQ进程对应的重传定时器retransmission timer在运行,除该第一HARQ进程之外的其他HARQ进程的重传定时器retransmission timer不运行或未运行;在第二通信设备的第一接口的DRX上持续定时器on duration timer和/或非激活定时器inactivity timer未运行;在第二通信设备的第二接口的DRX上对应的持续定时器on duration timer和/或非激活定时器inactivity timer未运行。
应理解,第二通信设备的第一接口可以为与网络设备通信的空口,例如Uu口;第二通信设备的第二接口可以为与第一通信设备通信的接口,例如,SL口或PC5口。相应上,上述“第一接口的DRX”可为Uu DRX,“第二接口的DRX”可为SL DRX。
另一种可能的实现方式中,可以根据运行的重传定时器retransmission timer对应的HARQ进程的类型,确定网络设备不发送或不调度第一目的地或第一SL连接的资源配置信息。
其中可选的,HARQ进程的类型包括配置第一信道的HARQ进程和未配置第一信道的HARQ进程。当第一信道为PUCCH时,HARQ进程的类型包括配置PUCCH的HARQ进程和未配置PUCCH的HARQ进程。
在本申请实施例中,当运行的重传定时器retransmission timer对应的HARQ进程的类型均为未配置第一信道的HARQ进程时,可以确定网络设备不发送或不调度第一目的地或第一SL连接的资源配置信息;或者,当运行的重传定时器retransmission timer对应的未配置第一信道的HARQ进程的数量大于或等于第一数量时,可以确定网络设备不发送或不调度第一目的地或第一SL连接的资源配置信息,其中,第一数量可以满足一定的条件,例如,第一数量为某个门限值(例如为1)。
图5示出了本申请实施例提供的另一种无线通信的方法500。
需要说明的是,图5所示的方法500中的部分步骤与图4所示的方法400相同,此处不再赘述,关于相同部分的详细说明,可参考图4中相关描述。
S501,第二通信设备确定该第二通信设备的第一目的地或第一侧行链路SL连接对应的第一混合自动重传请求HARQ进程没有或未被配置第一信道或第一资源,该第一信道或第一资源用于承载该第一HARQ进程对应的反馈信息。
其中,该第一HARQ进程可以为Uu口上用于SL的HARQ进程。可选的,第一HARQ进程包括至少一个HARQ进程。
关于上述步骤S501的详细说明,可参考方法400中的步骤S401的相关描述,此处不再赘述。
S502,第二通信设备发送指示信息,指示信息用于指示第二通信设备的该第一HARQ进程没有或未被配置第一信道或第一资源,相应的,第一通信设备接收该指示信息。
具体地,在本申请实施例中,第二通信设备可以为发送端TX,第一通信设备可以为接收端RX。
S503,第一通信设备启动该第一HARQ进程在SL上对应的至少一个SL进程对应的重传定时器retransmission timer。
应理解,上述至少一个SL进程用于第二通信设备与第一通信设备之间的接口上的通信。而上述步骤S503中至少一个SL进程对应的重传定时器retransmission timer为第一通信设备在SL DRX上的重传定时器。
具体地,在本申请实施例中,第一通信设备在收到该指示信息后,无论是否成功解码数据,均启动第一HARQ进程对应的retransmission timer。
可选的,第一通信设备若收到该指示信息,则可以在该指示信息中指示的第一HARQ进程对应的至少一个SL进程对应的混合自动重传请求往返时间定时器(hybrid automatic repeat request round trip time timer,HARQ RTT timer)超时后或超时时,启动对应的retransmission timer;或者,第一通信设备若收到该指示信息,则可以在该指示信息中指示的第一HARQ进程对应的SL进程对应的物理侧行链路反馈信道PSFCH传输或PSFCH资源结束后的第一符号或第一时隙,启动retransmission timer;或者,第一通信设备若收到该指示信息,则可以在收到或监听到该指示信息中指示的第一HARQ进程对应的至少一个SL进程对应的SCI时或后的第一符号或第一时隙,启动对应的retransmission timer。
在本申请实施例中,第一符号或第一时隙可以包括第一个符号或第一个时隙。或者,第一符号或第一时隙包括第N个符号或第N个时隙,N为正整数。或者,第一符号或第一时隙包括第N个符号或第N个时隙与偏移量的叠加,N为正整数。
一种可能的实现方式中,在第一目的地中的或在第一SL连接上的,与该至少一个SL进程对应的HARQ反馈去使能。或者说,SL HARQ反馈去使能。应理解,SL HARQ反馈去使能可以理解为,当第一通信设备接收第二通信设备发送的信息后,不再向第二通信设备反馈信息的接收情况,其中,接收情况信息包括ACK或NACK。
本申请实施例中的“SL进程”可替换为“HARQ进程”。
应理解,在本申请的多个实施例中,门限值(例如第一门限值、第二门限值、第三门限值等等)可以预设值,也可以是接收到的配置值,还可以是根据某个计算公式获得的值,本申请对此不作限定。
还应理解,在本申请的多个实施例中,“空口”和“接口”表达相同的含义,两者可以相互替换。
在终端设备之间的侧行链路通信过程中,发送端TX可能未收到接收端RX发送的物理侧行链路反馈信道PSFCH,或SL HARQ反馈,从而发送端不能确定接收端是否启动对应的重传定时器,例如TX不知道RX是否启动了上述PSFCH对应的重传定时器,可能会导致传输数据丢包。
例如,根据Uu DRX的逻辑,RX成功解码数据时不启动所述TX未收到的SL HARQ反馈/PSFCH对应SL进程(可替换为“SL HARQ进程”)的retransmission timer,否则若未成功解码数据则启动该retransmission timer。而TX由于未能收到SL HARQ反馈/PSFCH,故并不知道RX是否成功解码对应的数据,也就不知道RX在SL DRX是否启动对应的retransmission timer。TX未能收到SL HARQ反馈/PSFCH时,若采用mode1,则可能向基站发送NACK,随后基站可能调度相应SL进程的重传或新传资源,或其它SL进程的新传或重传资源。当TX收到其它SL进程的新传或重传资源时,由于并不知道RX在SL DRX是否启动对应的retransmission timer,并不确定RX是否处于active time,故若使用所述其它SL进程的新传或重传资源进行数据发送,且Rx若未启动所述retransmission timer时,RX可能发生丢包。
应理解,TX未收到RX发送的PSFCH的原因包括但不限于:TX发送PSFCH与接收PSFCH发生冲突导致未收到RX发送的PSFCH;TX向RX发送的SCI指示SL HARQ反馈去使能(disabled),或者说TX通过SCI指示RX对SCI调度的数据不发送HARQ反馈。
因此,为了避免SL通信中,数据丢包的情况发生,本申请实施例提供了一种无线通信的方法,能够避免SL通信中,由于TX未收到RX的PSFCH导致的丢包。即以下方法600。
图6示出了本申请实施例提供的一种无线通信的方法600。
S601,第二通信设备确定未收到第一PSFCH,该第一PSFCH用于第一通信设备向第二通信设备发送反馈信息。
具体地,在本申请实施例中,第二通信设备可以为TX,第一通信设备可以为RX。反馈信息可以为HARQ反馈。其中,第一PSFCH用于第一通信设备向第二通信设备发送反馈信息可以理解为,第一PSFCH用于承载第一通信设备向第二通信设备发送的反馈信息。此外,可选的,在上述步骤S601之前,第二通信设备可以为第一通信设备配置SL DRX或可以向第一通信设备发送数据,从而第一通信设备可以向第二通信设备发送相应的反馈信息或不向第二通信设备发送相应的反馈信息。
应理解,在本申请实施例中,第一通信设备与第二通信设备之间可以采用SL单播或SL组播进行通信。当采用SL单播进行通信时,第一通信设备与第二通信设备之间需建立SL连接。一个SL连接中可以对应多个SL进程(process)。当采用SL DRX时,一个SL进程对应于一个重传定时器retransmission timer,即一个SL连接可以对应多个重传定时器,而一个SL连接可以对应于一个持续定时器on duration timer和一个非激活定时器inactivity timer。或者可以理解为,一个SL连接中对应多个PSFCH,例如上述第一PSFCH,一个PSFCH对应于一个SL进程(例如第一PSFCH对应于第一SL进程),从而一个PSFCH 对应于一个重传定时器retransmission timer。当第一通信设备与第二通信设备之间采用SL组播进行通信时,第一通信设备与第二通信设备之间不需建立SL连接,此时,第一通信设备与第二通信之间的SL通信可用该SL组播业务对应的标识来指示,所述标识可包括目的标识,例如Destination layer-2ID。
可选的,该方法600可以包括步骤S602:
S602,第二通信设备确定不调度第二SL进程的数据,或,确定不启动第一PSFCH对应的重传定时器retransmission timer。
一种可能的实现方式中,第二通信设备根据第一通信设备侧的SL DRX相关定时器的运行情况,确定不调度第二SL进程的数据。例如,第二通信设备可以根据第一通信设备侧第二SL进程对应的重传定时器retransmission timer未运行/不运行,以及第二SL进程对应的SL连接或目的地(destination)对应的持续定时器on duration timer和非激活定时器inactivity timer均未运行/不运行,确定不调度第二SL进程的数据,和/或,不调度第一SL进程的新传。其中,第一SL进程对应于第一PSFCH。可选的,第二SL进程为除第一PSFCH对应的第一SL进程之外的其他SL进程。
另一种可能的实现方式中,第二通信设备确定其本地维护的与第一通信设备侧SL DRX定时器对应的SL DRX定时器中的第一PSFCH对应的重传定时器retransmission timer不启动。例如,当第二通信设备确定未收到第一PSFCH时,确定不启动与第一通信设备侧SL DRX定时器对应的第一PSFCH对应的重传定时器retransmission timer。
因此,通过上述第二通信设备在为第一通信设备配置了SL DRX,但是未收到第一通信设备的相应HARQ反馈信息时,确定不再调度相应SL进程的数据,或不启动相应反馈信息对应的重传定时器,避免了第二通信设备在未收到反馈信息时导致的数据丢包的情况。
在本申请实施例中,第二通信设备确定不调度第二SL进程的数据包括第二SL进程的新传或重传,或者说,第二通信设备确定的传输资源(例如SL grant)不用于第二SL进程的新传或重传。
在本申请实施例中,第二通信设备根据第一通信设备侧的定时器的运行情况,可包括:第二通信设备根据自身维护的与第一通信设备侧的定时器对应的定时器的运行情况。
可选的,上述第二SL进程不包括SL HARQ反馈去使能的SL进程。
可选的,步骤S601中,第二通信设备确定未收到第一PSFCH,可以替换为,第二通信设备的确定第一SCI对应的SL HARQ反馈去使能,其中第一SCI对应于第一SL进程。
应理解,在本申请实施例中,第二通信设备可以进行目的通信设备或目的业务
(destination)的选择和传输资源的选择,例如,上述选择的第一通信设备为第二通信设备选择的目的通信设备。或者,第二通信设备可以将候选目的通信设备或候选目的业务和确定或选择的传输资源进行匹配,从候选目的通信设备或候选目的业务中选择目的通信设备或目的业务,并为该目的通信设备或目的业务配置该确定或选择的传输资源。在为至少一个传输资源选定目的通信设备或目的业务之前,可从一个传输资源集合中选择至少一个传输资源。还应理解,传输资源可以为用于SL通信的传输资源,例如SL grant。
还应理解,在本申请实施例中,选择目的通信设备或目的业务(destination)可以替换为选择目的通信设备标识或目的业务标识(destination ID)。
可选的,第二通信设备进行的目的通信设备或目的业务标识选择和传输资源的选择可 以在步骤S601和S602之前。例如,在步骤S601和S602之前,第二通信设备为至少一个SL grant选定了目的通信设备(destination)或目的通信设备标识(destination ID),或者说第二通信设备为至少一个SL grant配置了目的通信设备(destination)或目的通信设备标识(destination ID)。
本申请中,“目的通信设备”可替换为“目的业务”。
可选的,该方法600可以包括步骤S603:
S603,第二通信设备在进行目的通信设备(destination)的选择时,使用的目的通信设备的SL DRX激活时间active time不考虑未收到PFSCH对应SL进程的重传定时器是否启动。
具体地,在本申请实施例中,第二通信设备在进行目的通信设备(destination)的选择时,使用的目的通信设备的SL DRX激活时间active time不考虑未收到PFSCH对应SL进程的重传定时器是否启动,也可理解为,第二通信设备在进行目的通信设备(destination)的选择时,可以根据传输资源是否在候选目的通信设备对应的SL DRX对应的激活时间内进行确定,或者,第二通信设备在进行目的通信设备选择时,可以根据传输资源与候选目的通信设备对应的SL DRX对应的激活时间之间的关系来进行。其中,候选目的通信设备对应的激活时间可以不考虑第二通信设备未收到PSFCH对应的SL进程的重传定时器retransmission timer是否启动。例如,当第二通信设备的某一个候选目的通信设备为第一通信设备时,在进行目的通信设备选择时,第一通信设备的激活时间不考虑第一PSFCH对应重传定时器retransmission timer是否启动,或者说,若第一通信设备对应的SL DRX仅有第一PSFCH对应的SL进程(即未收到PSFCH对应的SL进程)的重传定时器retransmission timer在运行时,即该SL DRX的其它SL进程的重传定时器未运行、且持续定时器和非激活定时器均未运行时,不将第一通信设备视为处于激活时间active time。
可选的,该方法600可以包括步骤S604:
S604,第二通信设备在进行传输资源选择时,根据候选目的通信设备的激活时间确定。
具体地,在本申请实施例中,第二通信设备在进行传输资源选择时,可以根据候选目的通信设备的激活时间进行确定,其中的候选目的通信设备的激活时间用于与传输资源进行匹配。
一种可能的实现方式中,第二通信设备根据候选目的通信设备的激活时间进行确定,可理解为,第二通信设备在进行传输资源选择时,当候选目的通信设备对应的SL DRX的持续定时器on duration timer、非激活定时器inactivity timer、第二通信设备收到候选目的通信设备发送的PSFCH对应的重传定时器retransmission timer中任一定时器在运行时,第二通信设备认为候选目的通信设备处于激活时间;或者,第二通信设备在进行传输资源选择时,关联或考虑的候选目的通信设备的激活时间不包括第二通信设备仅有未收到候选目的通信设备发送的PSFCH对应的重传定时器retransmission timer在运行、而该候选目的通信设备的SL DRX的其它SL进程的重传定时器未运行、且持续定时器和非激活定时器均未运行时的时间,换句话说,第二通信设备在确定候选目的通信设备的激活时间时,不考虑第二通信设备未收到候选目的通信设备发送的PSFCH对应的重传定时器retransmission timer是否运行,例如,当候选目的通信设备为第一通信设备时,第二通信设备在确定第一通信设备的激活时间时,不考虑第一PSFCH对应的重传定时器 retransmission timer的运行时间,或者,第二通信设备不考虑第一PSFCH对应的重传定时器retransmission timer是否运行。
另一种可能的实现方式中,候选目的通信设备的激活时间用于与传输资源进行匹配可理解为,第二通信设备可以根据第一传输资源是否在候选通信设备的激活时间内来确定是否选择或排除第一传输资源。应理解,第一传输资源为传输资源中的至少一个传输资源,例如第一传输资源为第一SL grant,第一SL grant为SL grant集合中的至少一个SL grant。
可选的,确定第一传输资源是否在候选目的通信设备的激活时间内,可以根据第一传输资源是否在候选目的通信设备的定时器的运行时间内确定。可选的,当第二通信设备确定第一传输资源满足第一条件时,确定将第一传输资源丢弃。例如,当第二通信设备确定第一传输资源不在任意候选目标通信设备的持续定时器on duration timer和非激活定时器inactivity timer的运行时间或收到PSFCH对应的重传定时器retransmission timer的运行时间内(即第一条件),第二通信设备可以将第一传输资源丢弃。
应理解,可选的,当第二通信设备中的所有传输资源均满足上述第一条件时,则可以触发资源重选,重新预留资源。
可选的,该方法600可以包括步骤S605:
S605,当第二通信设备确定未收到第一PSFCH时,第二通信设备不向网络设备请求传输资源。
具体地,在本申请实施例中,在mode1下,当第二通信设备为第一通信设备配置了SL DRX后,第二通信设备未收到第一通信设备的反馈信息时,即未收到第一PSFCH时,第二通信设备不向网络设备请求重传资源。
可选的,该方法600可以包括步骤S606:
S606,当第二通信设备确定调度第三SL进程的数据。
一种可能的实现方式中,第二通信设备根据第一通信设备侧的SL DRX相关定时器的运行情况,确定调度第三SL进程的数据。例如,第二通信设备在确定第一通信设备侧第三SL进程对应的SL连接或目的地(destination)对应的SL DRX的持续定时器on duration timer和非激活定时器inactivity timer均未运行/不运行,第三SL进程对应的重传定时器retransmission timer在运行时,确定可调度第三SL进程的数据。可选的,第三SL进程为除第一PSFCH对应的第一SL进程之外的其他SL进程。可选的,第三SL进程为第二通信设备收到的SL HARQ反馈或PSFCH对应的SL进程。
在本申请实施例中,第二通信设备确定可调度第三SL进程的数据,包括:第二通信设备确定可调度第三SL进程的新传或重传。
在本申请中,可调度某个SL进程或HARQ进程的数据,包括,可将资源关联至该SL进程或HARQ进程,或者,可将资源用于该SL进程或HARQ进程的数据传输。
在本申请中,可调度某个SL进程或HARQ进程的新传或重传,包括,可将资源关联至该SL进程或HARQ进程,或者,可将资源用于该SL进程或HARQ进程的新传或重传。
在终端设备之间的侧行链路通信过程中,对于HARQ反馈为去使能(disabled)的SCI调度的数据,TX不会收到RX的SL HARQ反馈,因此TX不知道RX是否启动SL DRX上对应的重传定时器retransmission timer,可能导致TX向RX发送数据丢包。
例如,TX发送的SCI指示SL HARQ反馈为disabled(即:指示RX对该SCI调度的 数据不发送HARQ反馈)时,若根据Uu DRX的逻辑,RX成功解码数据时,在SL DRX上不启动所述SL HARQ反馈disabled的SCI对应SL进程(可替换为“SL HARQ进程”)的retransmission timer,否则若未成功解码数据则启动该retransmission timer。而TX由于不会收到该SCI调度的数据的SL HARQ反馈/PSFCH,故并不知道RX是否成功解码对应的数据,也就不知道RX在SL DRX是否启动对应的retransmission timer,因此可能将资源(如SL grant)关联至除所述SL HARQ反馈disabled的SCI对应SL进程之外的其它SL进程,若使用所述其它SL进程的新传或重传资源进行数据发送,且RX若未启动所述retransmission timer时,RX可能发生丢包。
因此,为了避免上述SL HARQ反馈去使能,引起的RX丢包的情形,本申请实施例提供了一种无线通信的方法,能够避免由SL HARQ反馈去使能引起的RX丢包等资源浪费。即以下方法700。
图7示出了本申请实施例提供的另一种无线通信的方法700。
S701,第一通信设备接收第六信息,该第六信息用于指示SL HARQ反馈去使能。
具体地,在本申请实施例中,该第六信息可以由第二通信设备向第一通信设备发送。例如,第一通信设备为RX,第二通信设备为TX。可选的,第六信息承载于SCI中。
S702,第一通信设备接收第七信息,该第七信息用于指示重传资源信息或盲重传资源信息。
具体地,在本申请实施例中,该第七信息可以由第二通信设备向第一通信设备发送。
可选的,第七信息承载于SCI中。例如,第六信息和第七信息承载于同一SCI(如第一SCI)中。
S703,第一通信设备启动第六信息或第七信息对应的SL进程的重传定时器。
一种可能的实现方式中,当第六信息或第七信息对应的SL进程的HARQ RTT timer超时时,第一通信设备无论是否成功解码数据,第一通信设备均启动第六信息或第七信息对应的SL进程的重传定时器。
另一种可能的实现方式中,当第一通信设备接收到第六信息或第七信息对应的SCI时,无论是否成功解码数据,第一通信设备均启动第六信息或第七信息对应的SL进程的重传定时器。
因此,通过上述方法,当RX配置了SL DRX时,避免了有SL进程对应的SL HARQ反馈去使能导致的RX丢包。
