一、侧行链路(sidelink,SL),也可以称为旁链路,本申请实施例中均称为侧行链路。侧行链路用于终端设备和终端设备之间的通信,可以包括物理侧行链路共享信道(physical sidelink shared channel,PSSCH)和物理侧行链路控制信道(physical sidelink control channel,PSCCH)。其中,PSSCH用于承载侧行链路数据(SL data),PSCCH用于承载侧行链路控制信息(sidelinkcontrolinformation,SCI),所述SCI中包含的信息用于侧行链路调度分配(sidelink schedulingassigment,SL SA)。SL SA是用于数据调度相关的信息,比如,用于承载PSSCH的资源分配和/或调制编码机制(modulation and coding scheme,MCS)等信息。
可选的,侧行链路通信还可以包括:物理侧行链路反馈信道(physical sidelink feedback channel,PSFCH)。物理侧行链路反馈信道也可以简称为侧行链路反馈信道。物理侧行链路反馈信道可以用于传输侧行链路反馈控制信息(sidelink feedback control information,SFCI),侧行链路反馈控制信息也可以简称为侧行链路反馈信息。其中,侧行链路反馈控制信息可以包括信道状态信息(channel state information,CSI)和混合自动重传请求(hybrid automatic repeat request,HARQ)等信息中的一个或多个。其中,HARQ信息中可以包括确认信息(acknowledgement,ACK)或否定性确认(negtive acknowledgement,NACK)等。
二、Uu空口,Uu空口可以简称为Uu,Uu空口用于终端设备与接入网设备之间的通信。Uu空口可以理解为通用的用户设备(user equipment,UE)和网络之间的接口(universal  UE to network interface)。Uu空口的传输可以包括上行传输和下行传输。
其中,上行传输是指终端设备向接入网设备发送信息,上行传输的信息可以称为上行信息或上行信号。上行信息或上行信号中可以包括PUSCH,PUCCH,探测参考信号(sounding reference signal,SRS)中的一个或多个。用于传输上行信息或上行信号的信道称为上行信道,上行信道可以包括物理上行数据信道(physical uplink shared channel,PUSCH)和物理上行控制信道(physical uplink controlchannel,PUCCH)中的一个或多个。PUSCH用于承载上行数据,上行数据也可以称为上行数据信息。PUCCH用于承载终端设备反馈的上行控制信息(uplink control information,UCI)。示例的,UCI中可以包括终端设备反馈的信道状态信息(channel state information,CSI)、ACK和NACK等中的一个或多个。
下行传输是指接入网设备向终端设备发送信息,下行传输的信息可以为下行信息或下行信号。下行信息或下行信号可以包括PDSCH,PDCCH,信道状态信息参考信号(channel state information reference signal,CSI-RS),相位跟踪参考信号(phase tracking reference signal,PTRS)中的一个或多个。用于传输下行信息或下行信号的信道称为下行信道,下行信道可以包括物理下行数据信道(physical downlink shared channel,PDSCH)和物理下行控制信道(physical downlink control channel,PDCCH)中的一个或多个。所述PDCCH用于承载下行控制信息(downlink control information,DCI),PDSCH用于承载下行数据(data),下行数据也可称为下行数据信息。
三,信道接入过程,信道接入过程也可以称为先听后说(listen before talk,LBT)过程,以下均统一称为信道接入过程。信道接入过程的类型有两种:类型一,基于固定时长的信道接入过程,通信设备检测固定时长,如果在该固定时长内,在信道内检测到的信号的能量低于预设门限,则认为信道处于空闲状态,从而可以占用信道,否则需要重新竞争信道。
类型二,基于回退的信道接入过程,通信设备在一个竞争窗口中,随机选择一个数值A,当检测到至少A个空闲的时隙之后,才可以确定信道处于空闲状态,从而可以占用信道,否则需要重新竞争信道。其中,空闲的时隙是指在一个时隙内,在信道内检测到的信号的能量低于预设门限。在这种类型的信道接入过程中,引入了四种信道接入优先等级(channel access priority class,CAPC),不同的CAPC对应不同的信道接入参数,信道接入参数包括竞争窗口的大小、对应的业务情况以及信道占用时间(channel occupancy time,COT)信息等。COT是指信道接入过程成功之后,能使用这个信道的时长。
请参考图1,为本申请实施例适用的一种通信系统的网络架构示意图。该通信系统包括第一终端设备和第二终端设备,当然还可以包括其他终端设备,为了描述方便在此不再示出。第一终端设备和第二终端设备之间的直连通信链路即为侧行链路。
该通信系统还包括网络设备,网络设备可通过Uu接口与至少一个终端设备(如图1中所示的第一终端设备)进行通信。
图1中的网络设备可以为接入网设备,例如基站。其中,接入网设备在不同的系统对应不同的设备,例如在5G系统中对应5G中的接入网设备,例如gNB。图1中的网络设备可以是LTE系统中的演进型基站(evolutional node B,eNB),可以是全球移动通讯(global system of mobile communication,GSM)系统或码分多址(code division multiple access,CDMA)中的基站(base transceiver station,BTS),也可以是宽带码分多址(wideband code division multiple access,WCDMA)系统中的基站(nodeB,NB)等。尽管只在图1中示 出了第一终端设备和第二终端设备,应理解,网络设备可以为更多个终端设备提供服务,本申请实施例对通信系统中网络设备和终端设备的数量均不作限定。
图1中的终端设备可以为具有无线收发功能的设备或可设置于任一设备中的芯片,也可以称为用户设备(user equipment,UE)、接入终端、用户单元、用户站、移动站、移动台、远方站、远程终端、移动设备、用户终端、无线通信设备、用户代理或用户装置。本申请实施例中的终端设备可以是手机(mobile phone)、平板电脑(Pad)、带无线收发功能的电脑、虚拟现实(virtual reality,VR)终端、增强现实(augmented reality,AR)终端、工业控制(industrial control)中的无线终端、无人驾驶(self driving)中的无线终端、远程医疗(remote medical)中的无线终端、智能电网(smart grid)中的无线终端、运输安全(transportation safety)中的无线终端、智慧城市(smart city)中的无线终端、智慧家庭(smart home)中的无线终端等。
本申请实施例中的术语“系统”和“网络”可被互换使用。“多个”是指两个或两个以上,鉴于此,本申请实施例中也可以将“多个”理解为“至少两个”。“至少一个”,可理解为一个或多个,例如理解为一个、两个或更多个。例如,包括至少一个,是指包括一个、两个或更多个,而且不限制包括的是哪几个。例如,包括A、B和C中的至少一个,那么包括的可以是A、B、C、A和B、A和C、B和C、或A和B和C。同理,对于“至少一种”等描述的理解,也是类似的。“和/或”,描述关联对象的关联关系,表示可以存在三种关系,例如,A和/或B,可以表示:单独存在A,同时存在A和B,单独存在B这三种情况。另外,字符“/”,如无特殊说明,一般表示前后关联对象是一种“或”的关系。
本申请实施例提及“第一”、“第二”等序数词用于对多个对象进行区分,不用于限定多个对象的顺序、时序、优先级或者重要程度,并且“第一”、“第二”的描述也并不限定对象一定不同。
结合前面的描述,如图2所示,为本申请实施例提供的一种通信方法流程示意图。参见图2,该方法包括:
步骤200:第一终端设备获取第一资源。
其中,所述第一资源用于所述第一终端设备与第二终端设备之间进行侧行链路通信,或者用于所述第一终端设备与网络设备之间进行通信。第一资源可以包括多个资源,具体包括的资源数量,本申请实施例对此并不限定。
需要说明的是,第一资源可以为网络设备为第一终端设备分配的资源,也可以为第一终端设备自己选择的资源。第一终端设备可以多次获取资源,多次获取的资源的总和称为第一资源,例如第一资源可以是网络设备多次分配的资源,或者第一资源可以是第一终端设备多次选择的资源。
第一资源可以为非授权(unlicensed)频谱资源,即第一终端设备在使用第一资源中的资源进行数据传输之前,需要进行信道接入过程,如果信道接入过程成功,则可以使用该资源进行数据传输;如果信道接入过程失败,则不可以使用该资源进行数据传输。
针对任一资源,当所述第一终端设备在该资源的传输起点之前,没有完成信道接入过程,则确定信道接入过程失败,此时第一终端设备不可以使用该资源进行数据传输;当所述第一终端设备在该资源的传输起点之前,完成信道接入过程,则确定信道接入过程成功,此时第一终端设备可以使用该资源进行数据传输。
需要说明的是,第一终端设备执行信道接入过程的具体过程,本申请实施例对此并不 限定,具体可以参考现有技术中关于信道接入过程的描述,在此不再赘述。
本申请实施例中,在使用第一资源的过程中,第一终端设备可以对信道接入过程失败的数量进行统计。第一终端设备在进行统计时,可以按照以下任一方式进行统计。
方式一:统计在所述第一资源中,所述第一终端设备在用于单播的资源中发生信道接入过程失败的数量。
方式二:统计在所述第一资源中,所述第一终端设备在用于组播的资源中发生信道接入过程失败的数量。
方式三:统计在所述第一资源中,所述第一终端设备在用于广播的资源中发生信道接入过程失败的数量。
方式四:统计在所述第一资源中,所述第一终端设备在用于组播以及广播的资源中发生信道接入过程失败的数量。
方式五:统计在所述第一资源中,所述第一终端设备在用于单播以及广播的资源中发生信道接入过程失败的数量。
方式六:统计在所述第一资源中,所述第一终端设备在用于组播以及单播的资源中发生信道接入过程失败的数量。
方式七:统计在所述第一资源中,所述第一终端设备在属于预设的信道(channel)的资源中发生信道接入过程失败的数量。
方式八:统计在所述第一资源中,所述第一终端设备在属于预设的子带(subband)的资源中发生信道接入过程失败的数量。
方式九:不区分第一资源的类型,统计在第一资源中,所述第一终端设备发生信道接入过程失败的总数量。
第一终端设备在进行统计时,若确定发生预设数量的信道接入过程失败时,可以确定无线链路失败(radio link failure,RLF),预设数量为预设的值,也可以为网络设备配置的值,还可以根据其他方式确定的值,在此不再限定。举例来说,预设数量为5,第一终端设备按照方式九统计信道接入过程失败的数量。当第一终端设备确定信道接入过程失败的数量为5时,可以确定无线链路失败。
需要说明的是,第一终端设备在统计时,一种可能是实现方式中,第一终端设备可以统计连续发生信道接入过程失败的数量,在这种方式下,第一终端设备可以启动计数器,每当发生信道接入过程失败,将计数器的值加1;每当发生信道接入过程成功或第三定时器超时,将计数器的值重置为0。在每次发送信道接入过程失败时候,启动或重第三定时器。当计数器的值等于预设数量时,第一终端设备确定发送无线链路失败。需说明的是,计数器的最大次数,第三定时器的时长可以由网络设备配置的。
另一种可能是实现方式中,第一终端设备可以所有续发生信道接入过程失败的数量,在这种方式下,第一终端设备可以启动计数器,每当发生信道接入过程失败,将计数器的值加1。第一终端设备将计数器最终统计的值,作为信道接入过程失败的数量。当计数器的值大于或等于预设数量时,第一终端设备可以确定发送无线链路失败。
需要说明的是,步骤200,与步骤201至步骤204可以为相互独立的流程,也可以相互配合,本申请实施例对此并不限定。
步骤201:第一终端设备确定第一信息。
本申请实施例中,所述第一信息可以包括以下一项或多项:
1、信道接入过程结果,可以用于指示第一终端设备发生了信道接入过程失败。
可选地,还可以用于指示在第一资源中,哪些资源发生了信道接入过程失败,和/或,哪些资源发生了信道接入过程成功;
网络设备获取到第一资源的信道接入过程结果时,可以根据第一资源的信道接入过程结果,确定第一资源中哪些资源信道接入过程失败,哪些资源信道接入过程成功,从而可以确定是否为第一终端设备分配用于重传的资源,以及用于重传的资源的数量。
2、资源请求消息,所述资源请求消息用于请求在所述第一终端设备与第二终端设备之间的侧行链路进行重传的资源。
相应的,网络设备获取到资源请求消息时,可以根据资源请求消息确定是否为第一终端设备分配用于重传的资源。
进一步可选的,第一信息还可以包括以下一项或多项:
3、至少一个侧行链路载波标识;所述至少一个侧行链路载波标识为所述第一资源中,信道接入过程失败的资源所对应的侧行链路载波的标识,或者所述至少一个侧行链路载波标识为所述第一资源中,信道接入过程成功的资源所对应的侧行链路载波的标识。
当所述至少一个侧行链路载波标识为信道接入过程失败的资源所对应的侧行链路载波的标识时,网络设备根据所述至少一个侧行链路载波标识,可以确定发生信道接入过程失败的资源对应的载波,从而可以在为第一终端设备再次分配资源时,将所述至少一个侧行链路载波标识对应的载波排除。
相应的,当所述至少一个侧行链路载波标识为信道接入过程成功的资源所对应的侧行链路载波的标识时,网络设备可以确定发生信道接入过程成功的资源对应的载波,从而可以在为第一终端设备再次分配资源时,优先将所述至少一个侧行链路载波标识对应的载波中的资源分配给第一终端设备。
4、至少一个侧行链路混合自动重传请求(hybrid automatic repeat request,HARQ)标识;所述至少一个侧行链路HARQ标识为所述第一终端设备在所述第一资源中,发生信道接入过程失败的传输块所对应的侧行链路HARQ标识,或者所述至少一个侧行链路HARQ标识为所述第一终端设备在所述第一资源中,发送传输块成功的资源所对应的侧行链路HARQ标识。
第一终端设备在进行侧行链路通信时,会维护至少一个HARQ进程(process),每个HARQ进程都有一个HARQ标识,每个HARQ进程用于传输不同的传输块。网络设备可以根据所述至少一个侧行链路HARQ标识,确定是哪些传输块发送失败。
当网络设备在为第一终端设备分配重传资源时,可以向第一终端设备指示该重传资源所对应的侧行链路HARQ标识。第一终端设备根据网络设备指示的侧行链路HARQ标识,可以确定该重传资源,用于重传该侧行链路HARQ标识对应的传输块。
5、信道接入过程类型信息,用于指示所述第一终端设备对所述第一资源执行的信道接入过程的类型。
如前所述,本申请实施例中,信道接入过程的类型有两种:类型一,基于固定时长的信道接入过程;类型二,基于回退的信道接入过程。
通过信道接入过程类型信息,网络设备可以确定第一终端设备在进行信道接入过程时, 采用的信道接入过程类型。当网络设备再次为第一终端设备分配资源时,网络设备可以向第一终端设备指示信道接入过程的类型,网络设备指示的信道接入过程的类型,可以是根据信道接入过程类型信息确定的。
举例来说,当网络设备根据第一资源的信道接入过程结果确定,信道接入过程成功的第一资源的数量与第一资源包括的总的资源的数量的比值大于阈值,同时网络设备根据信道接入过程类型信息,第一终端设备采用的信道接入过程的类型为类型一,则可以指示第一终端设备继续采用类型一的信道接入过程,对网络设备分配的资源执行信道接入过程。其它情况不再赘述。
6、信道接入优先等级信息,用于指示所述第一终端设备对所述第一资源的执行信道接入过程所使用的信道接入优先等级。
如前所述,不同的信道接入优先等级对应不同的信道接入参数,信道接入参数包括竞争窗口的大小以及信道占用时间(channel occupancy time,COT)信息等。网络设备根据信道接入优先等级信息,可以确定在信道接入过程成功的资源中,第一终端设备在该资源中的COT等信息。
7、信道接入过程失败次数信息,用于指示所述第一资源中每个信道接入过程失败的资源对应的信道接入过程执行的次数。
结合前面的至少一个侧行链路载波标识,网络设备可以根据信道接入过程失败次数信息以及至少一个侧行链路载波标识,确定第一终端设备在信道接入过程时,信道接入过程失败次数较多的载波。当网络设备为第一终端设备分配资源时,可以避免将信道接入过程失败次数较多的载波中的资源分配给第一终端设备。
8、侧行链路类型信息,用于指示所述第一资源中信道接入过程失败的资源对应的资源类型。
步骤200中描述了,在第一资源中,第一终端设备对信道接入过程失败的数量进行统计时,会按照第一资源对应的资源类型进行统计,这里的侧行链路类型信息,就是指第一设备统计信道接入过程失败的资源时,统计的资源对应的资源类型。如前所述,资源类型可以包括以下任一项:

用于组播的资源;
用于广播的资源;
用于单播以及组播的资源;
用于组播以及广播的资源;
用于广播以及单播的资源;

属于预设的子带道的资源;
所有类型的资源,即用于单播、组播以及广播的资源。
步骤202:第一终端设备向网络设备发送所述第一信息。
需要说明的,第一信息可以通过物理层信令,或媒体接入控制(medium access control,MAC)控制元素(control element,CE)等方式进行传输,本申请实施例对此并不限定。
步骤203:网络设备获取来自第一终端设备的第一信息。
步骤204:网络设备根据所述第一信息为所述第一终端设备分配第二资源。
其中,所述第二资源用于所述第一终端设备与第二终端设备之间进行侧行链路通信,或者用于所述第一终端设备与所述网络设备之间进行通信。
示例性的,在步骤200中,第一终端设备确定发生无线链路失败时,或者第一终端设备确定信道接入过程失败的数量大于或等于预设数量时,启动第二定时器。第二定时器的定时时长为预设的或者网络设备配置的,本申请实施例对此并不限定。第一终端设备在第二定时器运行期间,执行无线链路恢复过程。
当在所述第二定时器超时时,若所述无线链路恢复失败,所述第一终端设备触发无线链路重建立过程。
在第二定时器运行期间,第一终端设备允许执行带宽部分(bandwidth part,BWP)切换。具体的,在第二定时器运行期间,第一终端设备可以从第一资源所属的第一BWP切换到第二BWP。第二BWP可以为网络设备为第一终端设备配置的任一BWP。
第二定时器超时,第一终端设备进行小区的无线链路恢复失败时,第一终端设备可以进行小区选择过程,选择一个小区,并通过这个小区进行随机接入过程,通过随机接入过程向网络设备发送重建立请求,网络设备在接收到重建立请求之后,会向第一终端设备发送响应消息,用于重建立。
在步骤201之前,第一终端设备可以在确定以下任一条件满足时,确定向网络设备发送第一信息。
条件一:第一终端设备接收到来自网络设备的第二信息时,所述第二信息用于指示所述第一终端设备发送所述第一信息。
在条件一中,网络设备通过第二信息直接指示第一终端设备发送第二信息,第一终端设备接收到第二信息,则可以向网络设备发送第一信息。
需要说明的是,第二信息还可以调度上行资源,第二信息调度的上行资源用于第一终端设备发送第一信息。第二信息调度的上行资源可以位于授权频谱上,也可以位于非授权频谱上,本申请实施例对此不做限定。
条件二:第一终端设备接收到来自网络设备的第三信息或者第二信息时,启动或重启第一定时器。其中,第一定时器的定时时长,可以为预设时长,也可以为网络设备配置的时长。
在第一定时器运行期间,第一终端设备接收到第三信息或者第二信息,可以重启第一定时器。当所述第一定时器超时,第一终端设备若在第一定时器运行期间没有接收到第三信息或者第二信息,则确定需要向网络设备发送第一信息。
其中,第二信息的含义和条件一中第二信息的含义相同,在此不再赘述。第一终端设备在确定向网络设备发送第一信息之前,网络设备已经为第一终端设备分配了资源。第三信息用于指示所述第一资源中的部分或全部资源,即第三信息为网络设备向第一终端设备分配资源的信息。
条件二中,通过设置第一定时器,使得第一终端设备每隔一段时间,向网络设备发送一次第一信息,避免了由于第一终端设备长时间不上报资源的使用结果,使得网络设备无法确定为第一终端设备的资源利用率。
条件三:第一终端设备确定在第一资源中,发生信道接入过程失败的数量大于或等于 预设数量。
第一终端设备具体如何确定发生信道接入过程失败的数量,可以参考步骤200中的描述,在此不再赘述。
需要说明的是,以上条件只是示例,还可能存在其他条件,在此不再逐一举例说明。
最终在步骤204,网络设备可以根据所述第一信息为所述第一终端设备分配第二资源。网络设备具体如何分配第二资源,可以参考前面的描述。需要说明的是,网络设备在分配第二资源时,可能只是参考第一信息,并不一定是按照第一信息分配第二资源。例如第一信息请求分配资源,网络设备若确定当前没有可以分配的资源,则可以不为第一终端设备分配第二资源,其它情况不在赘述。
