Description
本申请涉及通信技术领域,尤其涉及一种通信方法及设备。
当终端设备驻留在一个小区时,该终端设备可以使用当前小区配置的资源池(resource pool)在侧行链路(sidelink,SL)进行数据传输。目前,资源池的信息可以通过系统信息发送,而系统信息可能会发生改变。对于终端设备来说,如果系统信息发生了改变,终端设备就认为资源池发生了变化,那么终端设备需要开始使用新的系统信息提供的资源池。例如终端设备在使用一个新的资源池所包括的发送资源池时,需要对该发送资源池进行探测(sensing),以从发送资源池中选择可用的资源。在探测的过程中,终端设备只能使用新的资源池所提供的特殊发送资源池,终端设备在使用特殊发送资源池内的资源时,只需要从中随机选择即可。
由于没有探测的过程,终端设备在使用特殊发送资源池时,在选择资源时与其他终端设备产生碰撞的可能性较大,导致终端设备的传输性能下降。
发明内容
本申请实施例提供一种通信方法及设备,用于提高终端设备的传输性能。
第一方面,提供第一种通信方法,该方法包括:终端设备使用第二侧行链路发送资源;所述终端设备接收来自网络设备的第一系统信息;当所述第一系统信息指示的第一侧行链路发送资源与所述第二侧行链路发送资源不同时,所述终端设备使用所述第二侧行链路发送资源。
该方法可由第一通信装置执行,第一通信装置可以是通信设备或能够支持通信设备实现该方法所需的功能的通信装置,例如芯片系统。示例性地,所述通信设备为终端设备。
在本申请实施例中,如果第一系统信息指示的第一侧行链路发送资源与第二系统信息指示的第二侧行链路发送资源不同,且第一侧行链路发送资源没有可用的探测结果,则终端设备可以使用第二侧行链路发送资源,相当于,终端设备如果还未获得新的侧行链路发送资源的探测结果,则可以继续使用旧的侧行链路发送资源,而无需使用侧行链路特殊发送资源,提高了终端设备的传输性能。
结合第一方面,在第一方面的第一种可能的实施方式中,所述方法还包括如下的任意一种情况:所述终端设备接收第一消息,所述第一消息用于指示系统信息是否发生改变;或,所述终端设备接收第一消息,所述第一消息包括指示信息,所述指示信息用于指示在系统信息发生改变时,侧行链路发送资源是否发生变化;或,所述终端设备接收第一消息,当所述第一消息包括指示信息时,指示在系统信息发生改变时,侧行链路发送资源发生变化;或,当所述第一消息不包括指示信息时,指示在系统信息发生改变时,侧行链路发送资源不发生变化;或,所述终端设备接收第一消息,当所述第一消息包括时间信息时,所述第一消息指示在系统信息发生改变时,侧行链路发送资源发生变化,或,当所述第一消息不包括时间信息时,所述第一消息指示在系统信息发生改变时,侧行链路发送资源不发生变化。
在实际应用中,如上的几种情况可任选一种使用,或者具体选择哪种可通过网络设备配置,或通过协议规定。第一消息可以指示系统信息是否发生改变,如果系统信息发生变更,就认为侧行链路发送资源发生了改变;或者,第一消息也可以直接指示在系统信息发生改变时侧行链路发送资源是否会发生变 化,使得指示方式更为直接。而且第一消息的具体指示方式可以有多种,如上只是列举了其中的几种,本申请实施例并不限制第一消息究竟如何指示系统信息是否发生改变,或如何指示在系统信息发生改变时侧行链路发送资源是否会发生变化。
结合第一方面,在第一方面的第二种可能的实施方式中,所述终端设备可以将所述第一侧行链路发送资源与所述第二侧行链路发送资源相比较,确定所述第一侧行链路发送资源与所述第二侧行链路发送资源不同。
终端设备要确定第一侧行链路发送资源与第二侧行链路发送资源是否相同,可以由网络设备通过第一消息来指示,或者终端设备也可以自行比较后确定。采用终端设备自行比较的方式,无需网络设备通过第一消息来指示,有助于节省传输资源。
结合第一方面的第一种可能的实施方式,在第一方面的第三种可能的实施方式中,所述终端设备可以通过如下方式中的任意一种来使用所述第二侧行链路发送资源:所述终端设备对所述第一侧行链路发送资源进行探测,并在获取探测结果之前继续使用所述第二侧行链路发送资源;或者,所述终端设备使用所述第二侧行链路发送资源,直到获取第一侧行链路发送资源的探测结果。
如果网络设备通过第一消息指示系统信息是否发生变更,或者通过第一消息包括的指示信息来指示在系统信息发生改变时,侧行链路发送资源是否会发生变化,那么终端设备在确定第一侧行链路发送资源与第二侧行链路发送资源不同时,就可以直接使用第二侧行链路发送资源,且可以对第一侧行链路发送资源进行探测,在获取探测结果之前可以持续使用第二侧行链路发送资源,在获取探测结果时再开始使用第一侧行链路发送资源,以及停止使用第二侧行链路发送资源。通过这种方式,可以避免终端设备使用侧行链路特殊发送资源,减少终端设备之间在选择资源时产生的碰撞。
结合第一方面的第一种可能的实施方式,在第一方面的第四种可能的实施方式中,所述方法还可以包括如下的任意一种情况:在所述时间信息所指示的时刻到来之前,若所述终端设备获取了所述第一侧行链路发送资源的探测结果,则在获取所述第一侧行链路发送资源的探测结果时,所述终端设备使用所述第一侧行链路发送资源;或,在所述时间信息所指示的时刻到来时,若所述终端设备未获取所述第一侧行链路发送资源的探测结果,则在所述时间信息所指示的时刻到来时,所述终端设备使用侧行链路特殊发送资源,所述侧行链路特殊发送资源是所述第一系统信息指示的,或是第二系统信息指示的,所述第二系统信息是用于指示所述第二侧行链路发送资源的系统信息。
如果网络设备通过第一消息包括的时间信息来指示在系统信息发生改变时,侧行链路发送资源是否会发生变化,那么终端设备可以采用这种方式。以时间信息是定时器的信息为例。终端设备在接收第一系统信息后,可以启动定时器,该定时器的时长就是时间信息所指示的时长。在定时器超时之前,如果终端设备获取了第一侧行链路发送资源的探测结果,那么终端设备在获取第一侧行链路发送资源的探测结果时,就可以开始使用第一侧行链路发送资源。因为不同的终端设备获得探测结果的时间可能是不同的,通过这种实现方式,终端设备在获得第一侧行链路发送资源的探测结果时就可以使用第一侧行链路发送资源,从而不同的终端设备使用第一侧行链路发送资源的时间可能不同,也可以减小因为多个终端设备同时使用第一侧行链路发送资源而导致在选择资源时发生碰撞的几率。既然开始使用第一侧行链路发送资源,也就表明终端设备停止使用第二侧行链路发送资源。
在定时器超时时,如果终端设备还未获取第一侧行链路发送资源的探测结果,则终端设备可以开始使用侧行链路特殊发送资源,该侧行链路特殊发送资源可以是第一系统信息指示的第一侧行链路特殊发送资源,或者可以是第二系统信息指示的第二侧行链路特殊发送资源。既然开始使用侧行链路特殊发送资源,也就表明终端设备停止使用第二侧行链路发送资源。当然,终端设备在使用侧行链路特殊发送资 源的过程中,还可以继续对第一侧行链路发送资源进行探测,在获取第一侧行链路发送资源的探测结果时,终端设备可以停止使用侧行链路特殊发送资源,而开始使用第一侧行链路发送资源,以减小碰撞几率。系统信息发生变化,除了侧行链路资源可能变化之外,其他的一些配置也可能发生变化,因此终端设备需要尽量及时地应用新的系统信息所提供的新的配置。而且旧的侧行链路资源很可能也有时效性,例如网络设备已经通过新的系统信息指示了新的侧行链路资源,则旧的侧行链路资源很可能会在一段时间后失效,如果终端设备长时间应用旧的侧行链路资源,可能导致终端设备出现发送失败等情况。因此在本申请实施例中,为终端设备规定了时间信息,在时间信息所指示的时刻到来时,无论终端设备是否获取了第一侧行链路发送资源的探测结果,终端设备都可以停止使用第二侧行链路发送资源,而开始使用第一侧行链路发送资源或侧行链路特殊发送资源,以提高终端设备的发送成功率。
结合第一方面的第一种可能的实施方式,在第一方面的第五种可能的实施方式中,所述方法还可以包括如下的任意一种情况:在所述时间信息所指示的时刻到来之前,若所述终端设备获取了所述第一侧行链路发送资源的探测结果,则在所述时间信息所指示的时刻到来时,所述终端设备使用所述第一侧行链路发送资源;或,在所述时间信息所指示的时刻到来时,若所述终端设备未获取所述第一侧行链路发送资源的探测结果,则在所述时间信息所指示的时刻到来时,所述终端设备使用侧行链路特殊发送资源,所述侧行链路特殊发送资源是所述第一系统信息指示的,或是第二系统信息指示的,所述第二系统信息是用于指示所述第二侧行链路发送资源的系统信息。
如果网络设备通过第一消息包括的时间信息来指示在系统信息发生改变时,侧行链路发送资源是否会发生变化,那么终端设备也可以采用这种方式。
以时间信息是定时器的信息为例。终端设备在接收第一消息后的下一个修改周期的起始时刻,可以启动定时器,该定时器的时长就是时间信息所指示的时长。在定时器超时之前,如果终端设备获取了第一侧行链路发送资源的探测结果,那么终端设备继续使用第二侧行链路发送资源,直到定时器超时时,终端设备开始使用第一侧行链路发送资源。也就是说,在这种实现方式中,终端设备会等到定时器超时时再开始使用第一侧行链路发送资源,这种实现方式使得网络设备可以明确终端设备究竟是何时开始使用第一侧行链路发送资源,便于网络设备的管理。而且,既然开始使用第一侧行链路发送资源,也就表明终端设备停止使用第二侧行链路发送资源。
在定时器超时时,如果终端设备还未获取第一侧行链路发送资源的探测结果,则终端设备可以开始使用侧行链路特殊发送资源,该侧行链路特殊发送资源可以是第一系统信息指示的第一侧行链路特殊发送资源,或者可以是第二系统信息指示的第二侧行链路特殊发送资源。既然开始使用侧行链路特殊发送资源,也就表明终端设备停止使用第二侧行链路发送资源。当然,终端设备在使用侧行链路特殊发送资源的过程中,还可以继续对第一侧行链路发送资源进行探测,在获取第一侧行链路发送资源的探测结果时,终端设备可以停止使用侧行链路特殊发送资源,而开始使用第一侧行链路发送资源,以减小碰撞几率。系统信息发生变化,除了侧行链路资源可能变化之外,其他的一些配置也可能发生变化,因此终端设备需要尽量及时地应用新的系统信息所提供的新的配置。而且旧的侧行链路资源很可能也有时效性,例如网络设备已经通过新的系统信息指示了新的侧行链路资源,则旧的侧行链路资源很可能会在一段时间后失效,如果终端设备长时间应用旧的侧行链路资源,可能导致终端设备出现发送失败等情况。因此在本申请实施例中,为终端设备规定了时间信息,在时间信息所指示的时刻到来时,无论终端设备是否获取了第一侧行链路发送资源的探测结果,终端设备都可以停止使用第二侧行链路发送资源,而开始使用第一侧行链路发送资源或侧行链路特殊发送资源,以提高终端设备的发送成功率。
结合第一方面的第四种可能的实施方式或第一方面的第五种可能的实施方式,在第一方面的第六种 可能的实施方式中,所述终端设备在接收所述第一系统信息之后,以及在使用所述第一侧行链路发送资源或在使用所述侧行链路特殊发送资源之前,还可以包括如下的任意一种情况:所述终端设备继续使用所述第二系统信息所指示的侧行链路的全部配置;或,所述终端设备使用所述第一系统信息所指示的侧行链路的全部配置中除了所述第一侧行链路发送资源之外的其余的配置;或,所述终端设备使用所述第一系统信息所指示的侧行链路的全部配置中除了所述第一侧行链路发送资源之外的部分配置。
在接收所述第一系统信息之后,以及在使用第一侧行链路发送资源之前或在使用侧行链路特殊发送资源之前,终端设备可以使用第二系统信息所指示的侧行链路的全部配置,也就是说,终端设备除了使用第二侧行链路发送资源之外,也使用第二侧行链路接收资源等第二系统信息所指示的侧行链路的全部配置。而在获取第一侧行链路发送资源的探测结果之后,终端设备再一并使用第一系统信息所指示的侧行链路的全部配置,也就是说,在获取第一侧行链路发送资源的探测结果之后,终端设备停止使用第二系统信息所指示的侧行链路的全部配置,而改为使用第一系统信息所指示的侧行链路的全部配置。在这种方式下,终端设备可以整体更换侧行链路相关的配置,实现方式更为简单。

当然网络设备还可以包括核心网设备,但因为本申请实施例提供的技术方案主要涉及的是接入网设备,因此在后文中,如无特殊说明,则后文所描述的“网络设备”均是指接入网设备。
3)sidelink,在LTE系统中,D2D通信与V2X通信均属于终端设备通过sidelink接口与其他终端设备通信的过程。D2D与V2X均是基于PC5接口的通信,二者使用的资源可以统称为sidelink的资源。
4)V2X,在版本(Rel)-14/15/16版本中,V2X作为设备到设备(device-to-device,D2D)技术的一个主要应用顺利立项。V2X将在已有的D2D技术的基础上对V2X的具体应用需求进行优化,需要进一步减少V2X设备的接入时延,解决资源冲突问题。
V2X具体又包括车与车(vehicle-to-vehicle,V2V)、车与路侧基础设施(vehicle-to-infrastructure,V2I)、车与行人(vehicle-to-pedestrian,V2P)的直接通信,以及车与网络(vehicle-to-network,V2N)的通信交互等几种应用需求。如图1所示。V2V指的是车辆间的通信;V2P指的是车辆与人(包括行人、骑自行车的人、司机、或乘客)的通信;V2I指的是车辆与网络设备的通信,网络设备例如RSU,另外还有一种V2N可以包括在V2I中,V2N指的是车辆与基站/网络的通信。
其中,RSU包括两种类型:终端类型的RSU,由于布在路边,该终端类型的RSU处于非移动状态,不需要考虑移动性;基站类型的RSU,可以给与之通信的车辆提供定时同步及资源调度。
5)本申请实施例中的术语“系统”和“网络”可被互换使用。“至少一个”是指一个或者多个,“多个”是指两个或两个以上。“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的情况,其中A,B可以是单数或者复数。字符“/”一般表示前后关联对象是一种“或”的关系。“以下至少一项(个)”或其类似表达,是指的这些项中的任意组合,包括单项(个)或复数项(个)的任意组合。例如,a,b,或c中的至少一项(个),可以表示:a,b,c,a-b,a-c,b-c,或a-b-c,其中a,b,c可以是单个,也可以是多个。
以及,除非有相反的说明,本申请实施例提及“第一”、“第二”等序数词是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。例如,第一标识和第二标识,只是为了区分不同的标识,而并不是表示这两种标识的内容、优先级或者重要程度等的不同。
如上介绍了本申请实施例涉及的一些概念,下面介绍本申请实施例的技术特征。
V2X,是未来智能交通运输系统的关键技术。它使得车与车、车与基站、基站与基站之间能够通信。从而获得实时路况、道路信息、行人信息等一系列交通信息,从而提高驾驶安全性、减少拥堵、提高交通效率、提供车载娱乐信息等。
可参考图2,在LTE系统中,在覆盖范围内的终端设备根据基站通过Uu接口发送的配置消息获取在侧行链路上的发送配置,从而终端设备可以在侧行链路上向其他终端设备进行广播。
在LTE系统中,基站有两种控制车与车之间通过侧行链路通信的方式:模式(mode)3和mode4。
mode3可参考图3。基站通过专用信令(dedicated signal)向无线资源控制连接态(radio resource-connected)的终端设备发送专用资源(dedicated resource),该专用资源例如包括专用的侧行链路发送资源。终端设备获得专用信令携带的专用的侧行链路发送资源,可以通过该专用的侧行链路发送资源发送数据。其中,RRC连接态的终端设备还可以先向基站发送请求(request)消息,基站接收请求消息后通过专用信令向该终端设备发送专用资源。
mode4可参考图4。基站通过专用信令或广播信息向终端设备发送用于在侧行链路上进行传输的资源池(resource pool)的信息,该资源池例如包括侧行链路发送资源池(TX pool)、侧行链路接收资源池(RX pool)以及侧行链路特殊发送资源池(exceptional TX pool)。终端设备获得侧行链路发送资源池后,可以从该侧行链路发送资源池中选择资源以发送数据。其中,对于RRC连接态的终端设备,基站可以通过专用信令或广播信息发送资源池的信息,而对于RRC空闲态(idle)的终端设备,基站可以通过广播信息发送资源池的信息。广播信息例如为系统信息块(system information block,SIB)21或SIB26等。则RRC连接态的终端设备可以通过专用信令接收基站配置的资源池,例如包括侧行链路接收资源池、侧行链路发送资源池以及侧行链路特殊发送资源池,RRC空闲态的终端设备可以通过读系统广播SIB21和SIB26,获取侧行链路接收资源池、侧行链路发送资源池、以及侧行链路特殊发送资源池。
其中,侧行链路接收资源池用于告知终端设备,在侧行链路上需要在哪些资源上接收信号。侧行链路发送资源池用于终端设备在当前小区在侧行链路上传输时,从侧行链路发送资源池中选取资源进行传输。侧行链路特殊发送资源池用于在一些特殊情况下,例如进行小区切换、小区重选、或发生链路失败等情况下,终端设备可以在侧行链路特殊发送资源池中随机选取资源进行发送。
在NR系统中,类似地,侧行链路业务对应mode1和mode2,mode1的控制方式类似于LTE系统中的mode3,mode2的控制方式类似于LTE系统中的mode4。并且NR系统的侧行链路业务还可以通过侧行链路进行向一个终端设备单播或者向一组终端设备进行组播。对于mode 1和mode 3,基站可能分配侧行链路专用资源或者侧行链路资源池给终端设备,用于终端设备进行传输,对于mode 2和mode 4,基站 分配侧行链路资源池给终端设备,用于终端设备进行传输。其中,侧行链路专用资源是指专用于该终端设备进行传输的,该终端设备无需与其他终端设备竞争,也无需再次进行资源选择,而侧行链路资源池可能是供多个终端设备使用,终端设备也还需要从侧行链路资源池中再选择资源。
其中,终端设备在侧行链路发送资源池中挑选资源进行侧行链路传输时,会首先对侧行链路发送资源池进行sensing,并获取对侧行链路发送资源池的sensing结果。sensing是指,通过听取一段时间内侧行链路发送资源池内不同的资源的占用情况,来选取侧行链路发送资源池内当前没有被占用的资源进行传输,从而降低不同的终端设备因同时选取一个资源而造成冲突的概率。因此,当侧行链路发送资源池发生变化时,终端设备均需要重新对变化后的侧行链路发送资源池进行sensing。为了减少由于终端设备等待sensing结果而造成的发送中断,基站通常还会提供侧行链路特殊发送资源池,终端设备在使用侧行链路特殊发送资源池内的资源时,只需要从中随机选择即可,不需要对侧行链路特殊发送资源池进行sensing。
其中,系统信息一般是按周期发送的,基站通过系统信息向终端设备发送配置等信息。基站可以通过改变当前系统信息来改变某些配置。当然,基站并不是在任何时间都可以直接改变系统信息,系统信息的更改是要在修改周期(modification period)开始时完成,在整个修改周期内是不可以变化的。当基站想改变当前的系统信息时,需要发送用于通知系统信息改变的寻呼(paging)消息,并在下一个修改周期内广播新的系统信息。对于LTE小区,当任何系统信息发生变化时,SIB1中的值标签(value tag)值会加1。其中在LTE系统中,SIB1里包括一个value tag,只要有任何一个SIB发生了变化,该value tag的值都会加1。对于NR小区,每个SIB会单独对应一个value tag值,即SIB1中有一个数组,该数组通过不同的value tag分别指示具体是哪个SIB发生了变化。当某一个SIB发生变化时,对应的value tag的值将加1。在NR系统中还引入了区域特定(area specific)的系统信息(system information,SI),并设置了SI的area标识号(ID)。当系统信息中的area ID发生变化或者value tag发生变化时,基站都会在之前发送paging消息,通知系统信息改变。其中,对于area specific的SI来说,除了对应area ID之外,也对应SIB1中的value tag。对于终端设备来说,除了判断area ID是否发生了改变之外,一般也要判断value tag是否发生了改变,从而确定系统信息是否发生了变化。
对于终端设备来说,当在当前修改周期内收到系统信息要改变的寻呼消息时,会在下一个修改周期重新读取改变后的系统信息,并应用新的系统信息所提供的相应配置。针对LTE系统中支持侧行链路的终端设备,当侧行链路发送资源池发生变化时,在获取到对于新的侧行链路发送资源池的sensing结果前,终端设备需要使用新的系统信息提供的特殊发送资源池。在获得对新的侧行链路发送资源池的sensing结果后,再使用新的侧行链路发送资源池进行发送。
终端设备在使用特殊发送资源池时是不需要进行sensing的,碰撞几率较大,因此,由于使用特殊发送资源池,造成了终端设备的传输性能下降。而且,如果所有的终端设备均按照此方式实现,则在系统信息发生变化时,当前小区的所有的终端设备都会使用新的系统信息提供的特殊发送资源池,则进一步增加了碰撞的几率,造成系统信息改变时服务性能变差。
鉴于此,提供本申请实施例的技术方案。在本申请实施例中,如果第一系统信息指示的第一侧行链路发送资源与第二系统信息指示的第二侧行链路发送资源不同,且第一侧行链路发送资源没有可用的探测结果,则终端设备可以使用第二侧行链路发送资源,相当于,终端设备可以继续使用旧的侧行链路发送资源,而无需使用侧行链路特殊发送资源,提高了终端设备的传输性能。
本申请实施例提供的技术方案可以应用于sidelink场景,例如设备到设备(device-to-device,D2D)场景,可以是NR D2D场景也可以是LTE D2D场景等,或者例如V2X场景,可以是NR V2X场景也 可以是LTE V2X场景等。或者还可以应用于其他的场景或其他的通信系统,具体的不做限制。
下面介绍本申请实施例所应用的网络架构。请参考图5,为本申请实施例所应用的一种网络架构。
图5中包括网络设备和两个终端设备,分别为终端设备1和终端设备2,这两个终端设备均可以在网络设备覆盖下,或者这两个终端设备可以只有终端设备1在网络设备覆盖下,终端设备2不在网络设备覆盖下,或者这两个终端设备也可以在不同的网络设备覆盖下。这两个终端设备之间可以通过sidelink进行通信。图5以这两个终端设备均在图5中所示的一个网络设备的覆盖下为例。其中,这两个终端设备都是V2X终端设备。当然图5中的终端设备的数量只是举例,在实际应用中,网络设备可以为多个终端设备提供服务。
图5中的网络设备例如为接入网设备,例如基站,或者还可以是RSU等,图5中以基站为例。其中,接入网设备在不同的系统对应不同的设备,例如在第四代移动通信技术(the 4th generation,4G)系统中可以对应eNB,在5G系统中对应5G中的接入网设备,例如gNB。
其中,图5中的终端设备是以车载终端设备或车为例,但本申请实施例中的终端设备不限于此。
接下来结合附图介绍本申请实施例提供的技术方案。
本申请实施例提供一种通信方法,请参见图6,为该方法的流程图。在下文的介绍过程中,以该方法应用于图5所示的网络架构为例。另外,该方法可由两个通信装置执行,这两个通信装置例如为第一通信装置和第二通信装置。其中,第一通信装置可以是网络设备或能够支持网络设备实现该方法所需的功能的通信装置,或者可以是终端设备或能够支持终端设备实现该方法所需的功能的通信装置,当然还可以是其他通信装置,例如芯片系统。同理,第二通信装置可以是网络设备或能够支持网络设备实现该方法所需的功能的通信装置,或者可以是终端设备或能够支持终端设备实现该方法所需的功能的通信装置,当然还可以是其他通信装置,例如芯片系统。且对于第一通信装置和第二通信装置的实现方式均不做限制,例如这两个通信装置可以实现为相同的形式,例如均通过设备的形式实现,或者这两个通信装置也可以实现为不同的形式,例如第一通信装置通过设备的形式实现,第二通信装置通过芯片系统的方式实现,等等。其中,网络设备例如为基站。
为了便于介绍,在下文中,以该方法由网络设备和终端设备执行为例,也就是,以第一通信装置是网络设备、第二通信装置是终端设备为例。因为本实施例是以应用在图5所示的网络架构为例,因此,下文中所述的网络设备可以是图5所示的网络架构中的网络设备,下文中所述的终端设备可以是图5所示的网络架构中的终端设备1或终端设备2,如果下文中所述的终端设备是图5所示的网络架构中的终端设备1,那么下文中所述的其他终端设备可以是图5所示的网络架构中的终端设备2,或者,如果下文中所述的终端设备是图5所示的网络架构中的终端设备2,那么下文中所述的其他终端设备可以是图5所示的网络架构中的终端设备1。
S61、网络设备发送第二系统信息,终端设备接收来自网络设备的所述第二系统信息。
第二系统信息可以指示侧行链路资源,例如将第二系统信息指示的侧行链路资源称为第二侧行链路资源。在本申请实施例中,侧行链路资源例如包括D2D资源或V2X资源等,具体的不做限制。
侧行链路资源可以是专用资源,例如包括专用的发送资源,或专用的接收资源,或专用的发送资源和专用的接收资源。或者,侧行链路资源也可以是资源池,例如包括侧行链路发送资源池、侧行链路接收资源池或侧行链路特殊发送资源池中的至少一种。在后文中,所述的侧行链路发送资源可以是指侧行链路发送资源池,例如第一侧行链路发送资源可以是第一侧行链路发送资源池,或者侧行链路发送资源也可以是指专用资源或其他资源。同理,所述的侧行链路特殊发送资源可以是指侧行链路特殊发送资源池,例如第一侧行链路特殊发送资源可以是第一侧行链路特殊发送资源池,或者侧行链路特殊发送资源 也可以是指专用资源或其他资源;所述的侧行链路接收资源可以是指侧行链路接收资源池,例如第一侧行链路接收资源可以是第一侧行链路接收资源池,或者侧行链路接收资源也可以是指专用资源或其他资源。
例如,将第二系统信息指示的侧行链路发送资源称为第二侧行发送资源,将第二系统信息指示的侧行链路接收资源称为第二侧行接收资源,以及将第二系统信息指示的侧行链路特殊发送资源称为第二侧行特殊发送资源。终端设备在接收第二系统信息后,可以使用第二系统信息所指示的侧行链路资源,例如包括第二侧行链路发送资源、第二侧行链路接收资源或第二侧行链路特殊发送资源中的至少一种。例如终端设备在接收第二系统信息后,如果要在侧行链路发送数据,则可以使用第二侧行链路发送资源。当然,终端设备需要先对第二侧行链路发送资源进行sensing,在获得sensing结果之后,终端设备再使用第二侧行链路发送资源。
当然,第二系统信息除了指示侧行链路资源之外还可以指示其他的配置,具体的不做限制。
S62、网络设备生成第一消息。
作为第一消息的第一种实现方式,第一消息可以指示系统信息是否发生改变。
例如,第一消息为寻呼消息。在系统信息发生改变时,网络设备所发送的寻呼消息可以携带1比特(bit)的信息,通过这1比特的信息指示系统信息发生改变。而在系统信息不改变时,网络设备所发送的寻呼消息可以不携带这1比特的信息。因此,终端设备根据所接收的寻呼消息是否携带这1比特的信息,就可以确定系统信息是否会发生改变。
再例如,第一消息为SIB1。在系统信息发生改变时,网络设备所发送的SIB1中的相应的value tag的值会加1,而在系统信息不发生改变时,网络设备所发送的SIB1中的相应的value tag的值不变。因此,终端设备通过将新的SIB1中的value tag的值与之前接收的SIB1中的value tag的值进行比较,就能确定value tag的值是否发生了变化,从而确定相应系统信息是否发生了改变。
再例如,第一消息为SIB1。SIB1携带有area ID,当区域特定的系统信息发生改变时,SIB1中的area ID的值会发生变化,而在系统信息不发生改变时,网络设备所发送的SIB1的area ID的值会发生不变。因此,终端设备通过将SIB1中的area ID的值与之前接收的SIB1中的area ID的值进行比较,就能确定area ID的值是否发生了变化,从而确定系统信息是否发生了改变。
又例如,第一消息为对应于sidelink的SIB,该SIB可以携带area ID。在系统信息发生改变时,网络设备所发送的该SIB所携带的area ID的值会发生变化,而在系统信息发生改变时,网络设备所发送的该SIB所携带的area ID的值不会发生变化。因此,终端设备通过将新的SIB中的area ID的值与之前接收的SIB中的area ID的值进行比较,就能确定area ID的值是否发生了变化,从而确定系统信息是否发生了改变。
在第一消息的这种实现方式下,如果第一消息指示系统信息发生改变,则表示隐式指示侧行链路发送资源发生了改变,终端设备就认为侧行链路发送资源发生了改变,而如果第一消息指示系统信息不发生改变,则表示隐式指示侧行链路发送资源不发生改变,则终端设备就认为侧行链路发送资源不发生改变。
或者,作为第一消息的第二种实现方式,第一消息也可以指示,在系统信息发生改变时,侧行链路发送资源是否发生改变。
例如,第一消息包括指示信息,该指示信息可以指示,在系统信息发生改变时,侧行链路发送资源是否发生改变。例如该指示信息占用一个或多个比特。
例如第一消息为寻呼消息,则寻呼消息本身就会指示系统信息是否会发生改变,本申请实施例只是 在寻呼消息中额外增加了指示信息。那么,如果寻呼消息指示系统信息会发生改变,且指示信息指示在系统信息发生改变时,侧行链路发送资源会发生改变,终端设备就可以确定系统信息会发生改变,且在系统信息发生改变时,侧行链路发送资源会发生改变,从而终端设备可以确定第一侧行链路发送资源与第二侧行链路发送资源不同,那么终端设备可以在下一个修改周期读取新的系统信息,并获取新的侧行链路发送资源;或者,如果寻呼消息指示系统信息不会发生改变,且指示信息指示在系统信息发生改变时,侧行链路发送资源不会发生改变,或者,寻呼消息指示系统信息不会发生改变,终端设备就可以确定系统信息不会发生改变,从而终端设备可以确定第一侧行链路发送资源与第二侧行链路发送资源相同,那么终端设备可以在下一个修改周期可以不必读取新的系统信息,而可以继续使用第二侧行链路资源,例如继续使用第二侧行链路发送资源;或者,寻呼消息指示系统信息会发生改变,且指示信息指示在系统信息发生改变时,侧行链路发送资源不会发生改变,终端设备就可以确定系统信息会发生改变,且在系统信息发生改变时,侧行链路发送资源不会发生改变,从而终端设备可以确定第一侧行链路发送资源与第二侧行链路发送资源相同,那么终端设备可以在下一个修改周期读取新的系统信息,但可以不必获取新的侧行发送链路资源,而是继续使用旧的侧行链路发送资源,例如继续使用第二侧行链路发送资源。
如果第一消息携带了该指示信息,表明在系统信息发生改变时,侧行链路发送资源会发生改变,而如果第一消息未携带该指示信息,表明在系统信息发生改变时,侧行链路发送资源不会发生改变;或者,如果第一消息未携带该指示信息,表明在系统信息发生改变时,侧行链路发送资源会发生改变,而如果第一消息携带了该指示信息,表明在系统信息发生改变时,侧行链路发送资源不会发生改变。在这种情况下,该指示信息的取值可以任意,主要是通过该指示信息是否存在来指示侧行链路发送资源的变化情况。
或者,无论在系统信息发生改变时侧行链路发送资源是否会发生改变,第一消息都会携带该指示信息,在这种情况下,就可以通过指示信息的取值指示,在系统信息发生改变时,侧行链路发送资源是否会发生改变。以指示信息占用1比特为例。如果这1比特的取值为“1”,表明在系统信息发生改变时,侧行链路发送资源会发生改变,如果这1比特的取值为“0”,表明在系统信息发生改变时,侧行链路发送资源不会发生改变;或者,如果这1比特的取值为“1”,表明在系统信息发生改变时,侧行链路发送资源不会发生改变,如果这1比特的取值为“0”,表明在系统信息发生改变时,侧行链路发送资源会发生改变。
通过指示信息来显示指示侧行链路发送资源是否会发生改变,指示方式较为明确。例如第一消息为寻呼消息,本申请实施例可以在寻呼消息中额外增加指示信息,以显示指示侧行链路发送资源是否发生改变。或者第一消息也可以复用其他的已有的消息,或者第一消息也可以是本申请实施例所提供的专用的消息,具体的不做限制。
或者,作为第一消息的第三种实现方式,第一消息也可以指示,在系统信息发生改变时,侧行链路发送资源是否发生改变。在这种实现方式下,第一消息指示的内容可以与第一消息的第二种实现方式中指示的内容相同,但第一消息的实现方式不同。
例如,第一消息可以通过是否包含时间信息,来指示在系统信息发生改变时,侧行链路发送资源是否发生改变。当第一消息包含时间信息时,第一消息指示在系统信息发生改变时,侧行链路发送资源会发生改变,当第一消息不包含时间信息时,第一消息指示在系统信息发生改变时,侧行链路发送资源不会发生改变。
例如第一消息为寻呼消息,则寻呼消息本身就会指示系统信息是否会发生改变,本申请实施例只是在寻呼消息中额外增加了时间信息。那么,如果寻呼消息指示系统信息会发生改变,且第一消息包含时 间信息,终端设备就可以确定系统信息会发生改变,且在系统信息发生改变时,侧行链路发送资源会发生改变,从而终端设备可以确定第一侧行链路发送资源与第二侧行链路发送资源不同,那么终端设备可以在下一个修改周期读取新的系统信息,并获取新的侧行链路发送资源;或者,如果寻呼消息指示系统信息不会发生改变,且第一消息不包含时间信息,或者,寻呼消息指示系统信息不会发生改变,终端设备就可以确定系统信息不会发生改变,从而终端设备可以确定第一侧行链路发送资源与第二侧行链路发送资源相同,那么终端设备可以在下一个修改周期可以不必读取新的系统信息,可以继续使用第二侧行链路资源,例如使用第二侧行链路发送资源;或者,寻呼消息指示系统信息会发生改变,且第一消息不包含时间信息,终端设备就可以确定系统信息会发生改变,且在系统信息发生改变时,侧行链路发送资源不会发生改变,从而终端设备可以确定第一侧行链路发送资源与第二侧行链路发送资源相同,那么终端设备可以在下一个修改周期读取新的系统信息,但可以不必获取新的侧行发送链路资源,而是继续使用旧的侧行链路发送资源,例如使用第二侧行链路发送资源。
时间信息例如为定时器(timer)的信息,或者为第一时刻的信息,或者为时间偏置。定时器的信息例如包括定时器的时长,第一时刻可以是一个绝对时刻,例如第一时刻为15:30:05,时间偏置例如为相对于下一个修改周期的起始时刻的时间偏置,或者也可以是相对于其他时刻的时间偏置。关于时间信息的使用方法,将在后文介绍。
在第一消息的第三种实现方式下,第一消息可以通过是否包含时间信息来隐式指示在系统信息发生改变时,侧行链路发送资源是否发生改变,且时间信息也可以有进一步的应用,提高了信息的利用率。
S63、网络设备发送第一消息,终端设备接收来自网络设备的所述第一消息。
网络设备在生成第一消息后,可以发送第一消息。
S64、网络设备发送第一系统信息,终端设备接收来自网络设备的所述第一系统信息。
第一系统信息也可以指示侧行链路资源,例如将第一系统信息指示的侧行链路资源称为第一侧行链路资源。例如,将第一系统信息指示的侧行链路发送资源称为第一侧行发送资源,将第一系统信息指示的侧行链路接收资源称为第一侧行接收资源,以及将第一系统信息指示的侧行链路特殊发送资源称为第一侧行特殊发送资源。
当然,第一系统信息除了指示侧行链路资源之外还可以指示其他的配置,具体的不做限制。
如果网络设备发送了第一消息,那么本申请实施例以第一消息指示系统信息发生改变,或指示在系统信息发生改变时,侧行链路发送资源会发生改变为例。那么第一系统信息就是变化后的系统信息。
例如终端设备获知系统信息会发生改变,或者获知在系统信息发生改变时,侧行链路发送资源会发生改变,那么终端设备则在下一个修改周期内接收了变化后的系统信息,也就是第一系统信息。
或者,终端设备并不知道系统信息会发生变更,只是正常接收了第一系统信息。例如网络设备并未发送第一消息,或者终端设备没有成功接收第一消息。那么终端设备接收第一系统信息后,可以将第一侧行链路资源与第二侧行链路资源进行比较,以确定二者是否相同。例如终端设备可以将第一侧行链路发送资源与第二侧行链路发送资源进行比较,以确定二者是否相同。本申请实施例以终端设备确定第一侧行链路发送资源与第二侧行链路发送资源不同为例。
当然,在终端设备自行比较侧行链路资源的情况下,网络设备也可以无需发送第一消息,那么S62和S63都无需执行。
S64、当所述第一侧行链路发送资源与所述第二侧行链路发送资源不同时,所述终端设备使用所述第二侧行链路发送资源。
根据前文的介绍可知,如果第一侧行链路发送资源与第二侧行链路发送资源相同,则终端设备可以 继续使用第二侧行链路发送资源,对此不多赘述。
在本申请实施例中,如果第一侧行链路发送资源与第二侧行链路发送资源不同,那么终端设备可以继续使用第二侧行链路发送资源,而暂时不使用第一侧行链路发送资源,自然也不使用第一系统信息所提供的第一侧行链路特殊发送资源,从而可以减小在选择资源时的碰撞,提高终端设备的传输性能。
当第一侧行链路发送资源与第二侧行链路发送资源不同时,终端设备可以对第一侧行链路发送资源进行探测,并在探测过程中使用第二侧行链路发送资源。如果第一消息采用的是如上的第一种实现方式或第二种实现方式,那么,终端设备对第一侧行链路发送资源进行探测,在探测过程中使用第二侧行链路发送资源,在获取到对第一侧行链路发送资源的探测结果时,终端设备开始使用第一侧行链路发送资源,或者说,终端设备使用第二侧行链路发送资源,直到获取第一侧行链路发送资源的探测结果,终端设备开始使用第一侧行链路发送资源。而终端设备开始使用第一侧行链路发送资源,自然也就停止使用第二侧行链路发送资源。
对此可参考图7。可以看到,在系统信息发生改变之前,或者说是在终端设备接收第二系统信息时,终端设备可以使用第二侧行链路发送资源。在系统信息发生改变时,也就是终端设备接收第一系统信息时,终端设备可以继续使用第二侧行链路发送资源,当然在这个过程中,终端设备可以对第一侧行链路发送资源进行探测。在获取第一侧行链路发送资源的探测结果时,终端设备可以开始使用第一侧行链路发送资源。
另外,在获取第一侧行链路发送资源的探测结果之前,终端设备可以使用第二系统信息所指示的侧行链路的全部配置,也就是说,终端设备除了使用第二侧行链路发送资源之外,也使用第二侧行链路接收资源等第二系统信息所指示的侧行链路的全部配置。而在获取第一侧行链路发送资源的探测结果之后,终端设备再一并使用第一系统信息所指示的侧行链路的全部配置,也就是说,在获取第一侧行链路发送资源的探测结果之后,终端设备停止使用第二系统信息所指示的侧行链路的全部配置,而改为使用第一系统信息所指示的侧行链路的全部配置。在这种方式下,终端设备可以整体更换侧行链路相关的配置,实现方式更为简单。
或者,在获取第一侧行链路发送资源的探测结果之前,终端设备也可以只是使用第二系统信息所指示的第二侧行链路发送资源,而对于侧行链路的其他配置,全部使用第一系统信息所指示的配置。也就是说,在获取第一侧行链路发送资源的探测结果之前,终端设备使用第一系统信息所指示的侧行链路的全部配置中除了第一侧行链路发送资源之外的其余的所有配置。而在获取第一侧行链路发送资源的探测结果之后,终端设备使用第一侧行链路发送资源,而对于侧行链路的其他配置,终端设备继续使用第一系统信息所指示的配置。也就是说,在获取第一侧行链路发送资源的探测结果之后,终端设备只需更改侧行链路发送资源即可。通过这种方式,可以尽量及时应用新的系统信息所提供的相应配置。
或者,在获取第一侧行链路发送资源的探测结果之前,终端设备除了使用第二系统信息所指示的第二侧行链路发送资源之外,还可以使用第一系统信息所指示的一部分配置,而除此之外,终端设备使用第一系统信息所指示的配置。也就是说,在获取第一侧行链路发送资源的探测结果之前,终端设备可以使用第一系统信息所指示的侧行链路的全部配置中除了第一侧行链路发送资源之外的剩余的一部分配置。例如,终端设备可以使用第二系统信息指示的第二侧行链路发送资源和第二侧行链路接收资源,而对于侧行链路的其他配置,终端设备可以使用第一系统信息指示的内容。通过这种方式,可以尽量及时应用新的系统信息所提供的相应配置。
在本申请实施例中,终端设备在获取第一侧行链路发送资源的探测结果之前,可以继续使用第二侧行链路发送资源,而无需使用第一系统信息指示的第一侧行链路特殊发送资源,从而减小了在选择资源 时发生碰撞的几率,提高了终端设备的传输性能。并且由于不同终端设备由于能力不同,可能获取sensing的时间不同,可以在一段时间内小区内的所有终端设备相当于使用两个侧行链路资源,减少终端设备间对于选择资源的碰撞。
如果第一消息采用的是如上的第三种实现方式,也就是通过第一消息是否包含时间信息来指示在系统信息发生改变时,侧行链路发送资源是否发生变化。那么,当第一侧行链路发送资源与第二侧行链路发送资源不同时,终端设备可以有不同的实现过程,下面分别介绍。
1、作为终端设备的第一种实现过程,在时间信息所指示的时刻到来之前,若终端设备获取了第一侧行链路发送资源的探测结果,则在获取第一侧行链路发送资源的探测结果时,终端设备使用第一侧行链路发送资源。而在时间信息所指示的时刻到来时,若终端设备未获取第一侧行链路发送资源的探测结果,则在时间信息所指示的时刻到来时,终端设备使用侧行链路特殊发送资源,该侧行链路特殊发送资源是第一系统信息指示的,或是第二系统信息指示的。
其中,如果时间信息是定时器的信息,那么时间信息所指示的时刻,是指定时器超时的时刻;或者,如果时间信息是第一时刻的信息,那么时间信息所指示的时刻,就是第一时刻;或者,如果时间信息是时间偏置,例如该时间偏置是相对于下一个修改周期的时间偏移,那么时间信息所指示的时刻,是指与下一个修改周期之间的时间差等于该时间偏置的时刻。例如时间信息是相对于下一个修改周期的时间偏移,例如该时间偏移为5ms,而在第二时刻,与下一个修改周期之间的时间差就是5ms,那么该时间信息所指示的时刻就是第二时刻。
如果时间信息是定时器的信息,那么定时器的信息可以由网络设备配置,或者也可以通过协议规定。例如定时器的信息包括定时器的时长,定时器的时长可以根据多个终端设备进行sensing所需要的时间来确定,当然也可以根据其他因素确定,具体的不做限制。
另外,终端设备可以在一个修改周期开始时开启定时器,例如终端设备接收携带定时器的信息的第一消息时正好是一个修改周期开始时,那么终端设备接收第一消息时就可以启动定时器,或者,如果终端设备接收携带定时器的信息的第一消息的时刻处于一个修改周期内,那么终端设备可以等到下一个修改周期开始时再启动该定时器。如果是这种启动定时器的方式,则网络设备也可以跟终端设备同步维护具有相同的时长的定时器,网络设备可以与终端设备同步启动定时器,这样便于网络统一管理。
或者,终端设备也可以在接收到或读取了新的系统信息后启动定时器,例如终端设备先接收第一消息,第一消息携带定时器的信息,之后终端设备才接收第一系统信息,那么终端设备可以在接收第一系统信息时,或者在接收第一系统信息之后,再启动定时器。如果是这种情况,则网络设备可能没办法跟终端设备同步维护定时器,因为网络设备可能并不知道终端设备何时会读取第一系统信息,例如终端设备可能在网络设备第一次发送第一系统信息时读取失败,而在网络设备第二次发送第一系统信息时才读取成功,这些是网络设备所没办法控制的。
或者,终端设备也可以在接收携带定时器的信息的第一消息时,或者在接收该第一消息之后,启动定时器,这种启动方式较为及时。
对于终端设备究竟在何时启动定时器,本申请实施例不做限制。
以时间信息是定时器的信息为例。终端设备在接收第一系统信息后,可以启动定时器,该定时器的时长就是时间信息所指示的时长。在定时器超时之前,如果终端设备获取了第一侧行链路发送资源的探测结果,那么终端设备在获取第一侧行链路发送资源的探测结果时,就可以开始使用第一侧行链路发送资源。因为不同的终端设备获得探测结果的时间可能是不同的,通过这种实现方式,终端设备在获得第一侧行链路发送资源的探测结果时就可以使用第一侧行链路发送资源,从而不同的终端设备使用第一侧 行链路发送资源的时间可能不同,也可以减小因为多个终端设备同时使用第一侧行链路发送资源而导致在选择资源时发生碰撞的几率。另外,终端设备在获取第一侧行链路发送资源的探测结果时,也可以停止定时器,此时定时器可能刚好超时,也可能还未超时,但终端设备不必等待定时器超时,只要获取了第一侧行链路发送资源的探测结果,就可以停止定时器。而且,既然开始使用第一侧行链路发送资源,也就表明终端设备停止使用第二侧行链路发送资源。
对此可参考图8A。可以看到,在系统信息发生改变之前,或者说是在终端设备接收第二系统信息时,终端设备可以使用第二侧行链路发送资源。在系统信息发生改变时,也就是终端设备接收第一系统信息时,终端设备可以继续使用第二侧行链路发送资源,当然在这个过程中,终端设备可以对第一侧行链路发送资源进行探测。在获取第一侧行链路发送资源的探测结果时,定时器还未超时,则终端设备可以开始使用第一侧行链路发送资源。在这种情况下,终端设备无需使用侧行链路特殊发送资源,减小了碰撞几率,提高了终端设备的传输性能。并且由于不同的终端设备的能力不同,获取探测结果的时间可能不同,在一段时间内小区内的所有终端设备相当于可以使用两个侧行链路资源,减少终端设备间对于选择资源的碰撞。
但很有可能,在定时器超时时,终端设备还未获取第一侧行链路发送资源的探测结果。如果是这种情况,终端设备可以开始使用侧行链路特殊发送资源,该侧行链路特殊发送资源可以是第一系统信息指示的第一侧行链路特殊发送资源,或者可以是第二系统信息指示的第二侧行链路特殊发送资源。既然开始使用侧行链路特殊发送资源,也就表明终端设备停止使用第二侧行链路发送资源。当然,终端设备在使用侧行链路特殊发送资源的过程中,还可以继续对第一侧行链路发送资源进行探测,在获取第一侧行链路发送资源的探测结果时,终端设备可以停止使用侧行链路特殊发送资源,而开始使用第一侧行链路发送资源,以减小碰撞几率。
对此可参考图8B。在图8B可以看到,在系统信息发生改变之前,或者说是在终端设备接收第二系统信息时,终端设备可以使用第二侧行链路发送资源。在系统信息发生改变时,也就是终端设备接收第一系统信息时,终端设备可以继续使用第二侧行链路发送资源,当然在这个过程中,终端设备可以对第一侧行链路发送资源进行探测。而在定时器超时时,终端设备还未获取第一侧行链路发送资源的探测结果,因此终端设备可以开始使用侧行链路特殊发送资源。在终端设备使用侧行链路特殊发送资源的过程中,终端设备继续对第一侧行链路发送资源进行探测。在获取第一侧行链路发送资源的探测结果时,终端设备可以开始使用第一侧行链路发送资源。
系统信息发生变化,除了侧行链路资源可能变化之外,其他的一些配置也可能发生变化,因此终端设备需要尽量及时地应用新的系统信息所提供的新的配置。而且旧的侧行链路资源很可能也有时效性,例如网络设备已经通过新的系统信息指示了新的侧行链路资源,则旧的侧行链路资源很可能会在一段时间后失效,如果终端设备长时间应用旧的侧行链路资源,可能导致终端设备出现发送失败等情况。因此在本申请实施例中,为终端设备规定了时间信息,在时间信息所指示的时刻到来时,无论终端设备是否获取了第一侧行链路发送资源的探测结果,终端设备都可以停止使用第二侧行链路发送资源,而开始使用第一侧行链路发送资源或侧行链路特殊发送资源,以提高终端设备的发送成功率。
另外,在接收所述第一系统信息之后,以及在使用第一侧行链路发送资源之前或在使用侧行链路特殊发送资源之前,终端设备可以使用第二系统信息所指示的侧行链路的全部配置,也就是说,终端设备除了使用第二侧行链路发送资源之外,也使用第二侧行链路接收资源等第二系统信息所指示的侧行链路的全部配置。而在获取第一侧行链路发送资源的探测结果之后,终端设备再一并使用第一系统信息所指示的侧行链路的全部配置,也就是说,在获取第一侧行链路发送资源的探测结果之后,终端设备停止使 用第二系统信息所指示的侧行链路的全部配置,而改为使用第一系统信息所指示的侧行链路的全部配置。在这种方式下,终端设备可以整体更换侧行链路相关的配置,实现方式更为简单。
或者,在接收所述第一系统信息之后,以及在使用第一侧行链路发送资源之前或在使用侧行链路特殊发送资源之前,终端设备也可以只是使用第二系统信息所指示的第二侧行链路发送资源,而对于侧行链路的其他配置,全部使用第一系统信息所指示的配置。也就是说,在获取第一侧行链路发送资源的探测结果之前,终端设备使用第一系统信息所指示的侧行链路的全部配置中除了第一侧行链路发送资源之外的其余的所有配置。而在获取第一侧行链路发送资源的探测结果之后,终端设备使用第一侧行链路发送资源,而对于侧行链路的其他配置,终端设备继续使用第一系统信息所指示的配置。也就是说,在获取第一侧行链路发送资源的探测结果之后,终端设备只需更改侧行链路发送资源即可。通过这种方式,可以尽量及时应用新的系统信息所提供的相应配置。
或者,在接收所述第一系统信息之后,以及在使用第一侧行链路发送资源之前或在使用侧行链路特殊发送资源之前,终端设备除了使用第二系统信息所指示的第二侧行链路发送资源之外,还可以使用第一系统信息所指示的一部分配置,而除此之外,终端设备使用第一系统信息所指示的配置。也就是说,在获取第一侧行链路发送资源的探测结果之前,终端设备可以使用第一系统信息所指示的侧行链路的全部配置中除了第一侧行链路发送资源之外的剩余的一部分配置。例如,终端设备可以使用第二系统信息指示的第二侧行链路发送资源和第二侧行链路接收资源,而对于侧行链路的其他配置,终端设备可以使用第一系统信息指示的内容。通过这种方式,可以尽量及时应用新的系统信息所提供的相应配置。
2、作为终端设备的第二种实现过程,在时间信息所指示的时刻到来之前终端设备获取了所述第一侧行链路发送资源的探测结果,则在时间信息所指示的时刻到来时,终端设备使用第一侧行链路发送资源。既然开始使用第一侧行链路发送资源,自然也就停止使用第二侧行链路发送资源。而在时间信息所指示的时刻到来时,若终端设备未获取第一侧行链路发送资源的探测结果,则在时间信息所指示的时刻到来时,终端设备使用侧行链路特殊发送资源,侧行链路特殊发送资源是第一系统信息指示的,或是第二系统信息指示的。既然开始使用侧行链路特殊发送资源,自然也就停止使用第二侧行链路发送资源。
关于对时间信息的解释、对于定时器的信息的解释以及对于定时器的启动时刻等内容的介绍,可参考终端设备的第一种实现过程中的相关内容。
以时间信息是定时器的信息为例。终端设备在接收第一消息后的下一个修改周期的起始时刻,可以启动定时器,该定时器的时长就是时间信息所指示的时长。在定时器超时之前,如果终端设备获取了第一侧行链路发送资源的探测结果,那么终端设备继续使用第二侧行链路发送资源,直到定时器超时时,终端设备开始使用第一侧行链路发送资源。也就是说,在这种实现方式中,终端设备会等到定时器超时时再开始使用第一侧行链路发送资源,这种实现方式使得网络设备可以明确终端设备究竟是何时开始使用第一侧行链路发送资源,便于网络设备的管理。而且,既然开始使用第一侧行链路发送资源,也就表明终端设备停止使用第二侧行链路发送资源。
对此可参考图9A。可以看到,在系统信息发生改变之前,或者说是在终端设备接收第二系统信息时,终端设备可以使用第二侧行链路发送资源。在系统信息发生改变时,也就是终端设备接收第一系统信息时,终端设备可以继续使用第二侧行链路发送资源,当然在这个过程中,终端设备可以对第一侧行链路发送资源进行探测。在获取第一侧行链路发送资源的探测结果时,定时器还未超时,则终端设备可以继续使用第二侧行链路发送资源,而在定时器超时时,终端设备开始使用第一侧行链路发送资源。在这种情况下,终端设备无需使用侧行链路特殊发送资源,减小了碰撞几率,提高了终端设备的传输性能。
但很有可能,在定时器超时时,终端设备还未获取第一侧行链路发送资源的探测结果。如果是这种 情况,终端设备可以开始使用侧行链路特殊发送资源,该侧行链路特殊发送资源可以是第一系统信息指示的第一侧行链路特殊发送资源,或者可以是第二系统信息指示的第二侧行链路特殊发送资源。既然开始使用侧行链路特殊发送资源,也就表明终端设备停止使用第二侧行链路发送资源。当然,终端设备在使用侧行链路特殊发送资源的过程中,还可以继续对第一侧行链路发送资源进行探测,在获取第一侧行链路发送资源的探测结果时,终端设备可以停止使用侧行链路特殊发送资源,而开始使用第一侧行链路发送资源,以减小碰撞几率。
对此可参考图9B。在图9B可以看到,在系统信息发生改变之前,或者说是在终端设备接收第二系统信息时,终端设备可以使用第二侧行链路发送资源。在系统信息发生改变时,也就是终端设备接收第一系统信息时,终端设备可以继续使用第二侧行链路发送资源,当然在这个过程中,终端设备可以对第一侧行链路发送资源进行探测。而在定时器超时时,终端设备还未获取第一侧行链路发送资源的探测结果,因此终端设备可以开始使用侧行链路特殊发送资源。在终端设备使用侧行链路特殊发送资源的过程中,终端设备继续对第一侧行链路发送资源进行探测。在获取第一侧行链路发送资源的探测结果时,终端设备可以开始使用第一侧行链路发送资源。
系统信息发生变化,除了侧行链路资源可能变化之外,其他的一些配置也可能发生变化,因此终端设备需要尽量及时地应用新的系统信息所提供的新的配置。而且旧的侧行链路资源很可能也有时效性,例如网络设备已经通过新的系统信息指示了新的侧行链路资源,则旧的侧行链路资源很可能会在一段时间后失效,如果终端设备长时间应用旧的侧行链路资源,可能导致终端设备出现发送失败等情况。因此在本申请实施例中,为终端设备规定了时间信息,在时间信息所指示的时刻到来时,无论终端设备是否获取了第一侧行链路发送资源的探测结果,终端设备都可以停止使用第二侧行链路发送资源,而开始使用第一侧行链路发送资源或侧行链路特殊发送资源,以提高终端设备的发送成功率。
另外,在接收所述第一系统信息之后,以及在使用第一侧行链路发送资源之前或在使用侧行链路特殊发送资源之前,终端设备可以使用第二系统信息所指示的侧行链路的全部配置,也就是说,终端设备除了使用第二侧行链路发送资源之外,也使用第二侧行链路接收资源等第二系统信息所指示的侧行链路的全部配置。而在获取第一侧行链路发送资源的探测结果之后,终端设备再一并使用第一系统信息所指示的侧行链路的全部配置,也就是说,在获取第一侧行链路发送资源的探测结果之后,终端设备停止使用第二系统信息所指示的侧行链路的全部配置,而改为使用第一系统信息所指示的侧行链路的全部配置。在这种方式下,终端设备可以整体更换侧行链路相关的配置,实现方式更为简单。
或者,在接收所述第一系统信息之后,以及在使用第一侧行链路发送资源之前或在使用侧行链路特殊发送资源之前,终端设备也可以只是使用第二系统信息所指示的第二侧行链路发送资源,而对于侧行链路的其他配置,全部使用第一系统信息所指示的配置。也就是说,在获取第一侧行链路发送资源的探测结果之前,终端设备使用第一系统信息所指示的侧行链路的全部配置中除了第一侧行链路发送资源之外的其余的所有配置。而在获取第一侧行链路发送资源的探测结果之后,终端设备使用第一侧行链路发送资源,而对于侧行链路的其他配置,终端设备继续使用第一系统信息所指示的配置。也就是说,在获取第一侧行链路发送资源的探测结果之后,终端设备只需更改侧行链路发送资源即可。通过这种方式,可以尽量及时应用新的系统信息所提供的相应配置。
或者,在接收所述第一系统信息之后,以及在使用第一侧行链路发送资源之前或在使用侧行链路特殊发送资源之前,终端设备除了使用第二系统信息所指示的第二侧行链路发送资源之外,还可以使用第一系统信息所指示的一部分配置,而除此之外,终端设备使用第一系统信息所指示的配置。也就是说,在获取第一侧行链路发送资源的探测结果之前,终端设备可以使用第一系统信息所指示的侧行链路的全 部配置中除了第一侧行链路发送资源之外的剩余的一部分配置。例如,终端设备可以使用第二系统信息指示的第二侧行链路发送资源和第二侧行链路接收资源,而对于侧行链路的其他配置,终端设备可以使用第一系统信息指示的内容。通过这种方式,可以尽量及时应用新的系统信息所提供的相应配置。
通过本申请实施例提供的方法,能让终端设备知道在系统信息改变时,侧行链路发送资源是否会发生变化,无需终端设备进行识别,降低终端设备的复杂度。而且,如果侧行链路发送资源发生改变,终端设备可以采用当前正在使用的侧行链路发送资源,而无需使用新的侧行链路特殊发送资源,可以降低在选择资源时的碰撞几率,提高终端设备的通信质量。
