Description

设置方法、终端设备和网络设备 技术领域
本申请涉及通信领域,并且更具体地,涉及设置方法、终端设备和网络设备。
背景技术
设备到设备通信是基于终端到终端(D2D,Device to Device)技术的一种侧行链路(SL,Sidelink)传输技术,与传统的蜂窝系统中通信数据通过基站接收或者发送的方式不同,具有更高的频谱效率以及更低的传输时延。车联网系统采用终端到终端直接通信的方式,在第三代合作伙伴计划(3GPP,3rd Generation Partnership Project)定义了两种传输模式:第一模式和第二模式。在第二模式中,终端可以在预配置或网络配置的资源池中选取一个资源进行数据的侧行传输。在终端选取了传输资源后,如果直接在这些资源上进行数据发送,有可能存在两个终端选取了相同的传输资源而发生资源冲突。为了解决这个问题,在新空口-车辆到其他设备(NR-V2X,New Radio-Vehicle to Everything)中引入了资源抢占(pre-emption)和重评估(re-evaluation)机制,使得终端在使用选取的资源之前可以判断是否与其他终端存在资源冲突,如果没有冲突,可以继续使用选取的传输资源,如果有资源冲突,则需要根据相应的机制进行避让和资源重选,以避免资源冲突。
为了降低能耗,一些终端没有侧行数据的接收能力,也就是没有侦听能力。当一个资源池中既支持通过随机选取的方式获取传输资源、也支持通过侦听的方式获取传输资源时,没有侦听能力的终端随机选取资源,之后不会进行re-evaluation或pre-emption检测,而是直接使用选取的资源进行侧行传输;而有侦听能力的终端选取了传输资源之后,在使用该资源进行侧行传输之前,需要进行re-evaluation或pre-emption检测,以判断是否和其他终端发生资源冲突。例如对于pre-emption检测,当有侦听能力的终端检测到发生资源冲突,并且该终端的优先级低于有冲突的终端,并且检测到其他终端的参考信号接收功率(RSRP,Reference Signal Received Power)高于门限时,此时该终端会重新选取资源,以避免和其他终端的冲突;而如果该终端的优先级高于有冲突的终端,则该终端不会进行资源重选,而是期望与其有冲突的终端进行资源重选,即具有高优先级的终端可以优先使用该冲突的资源。但是,如果其他有冲突的终端是没有侦听能力的终端,也就不会进行pre-emption检测,也不会进行资源重选,从而导致的后果是低优先级的终端可以避免和没有侦听能力的终端之间的资源冲突,但是高优先级的终端无法避免和没有侦听能力的终端之间的资源冲突,即没有侦听能力的终端会和具有侦听能力的高优先级的数据传输资源存在冲突,从而影响高优先级的数据传输的性能。

为便于理解本申请实施例的技术方案,以下对本申请实施例的相关技术进行说明,以下相关技术作为可选方案与本申请实施例的技术方案可以进行任意结合,其均属于本申请实施例的保护范围。
在侧行通信中,根据进行通信的终端所处的网络覆盖情况,可以分为网络覆盖内侧行通信,部分网络覆盖侧行通信,及网络覆盖外侧行通信,分别如图1A、图1B和图1C所示。
如图1A所示,在网络覆盖内侧行通信中,所有进行侧行通信的终端均处于同一基站的覆盖范围内,这些终端均可以通过接收基站的配置信令,基于相同的侧行配置进行侧行通信。
如图1B所示,在部分网络覆盖侧行通信情况下,部分进行侧行通信的终端位于基站的覆盖范围内,这部分终端终端能够接收到基站的配置信令,而且根据基站的配置进行侧行通信。而位于网络覆盖范围外的终端,无法接收基站的配置信令在这种情况下,网络覆盖范围外的终端将根据预配置(pre-configuration)信息及位于网络覆盖范围内的终端发送的物理侧行广播信道(PSBCH,Physical Sidelink Broadcast Channel)中携带的信息确定侧行配置,进行侧行通信。
如图1C所示,对于网络覆盖外侧行通信,所有进行侧行通信的终端均位于网络覆盖范围外,所有终端均根据预配置信息确定侧行配置进行侧行通信。
设备到设备通信是基于D2D的一种侧行链路传输技术,与传统的蜂窝系统中通信数据通过基站接收或者发送的方式不同,因此具有更高的频谱效率以及更低的传输时延。车联网系统采用终端到终端直接通信的方式,在3GPP定义了两种传输模式:第一模式和第二模式。
第一模式:终端的传输资源是由基站分配的,终端根据基站分配的资源在侧行链路上进行数据的发送;基站可以为终端分配单次传输的资源,也可以为终端分配半静态传输的资源。如图1A中,终端位于网络覆盖范围内,网络为终端分配侧行传输使用的传输资源。
第二模式:终端在资源池中选取一个资源进行数据的传输。如图1C中,终端位于小区覆盖范围外,终端在预配置的资源池中自主选取传输资源进行侧行传输;或者在图1A中,终端在网络配置的资源池中自主选取传输资源进行侧行传输。
在NR-V2X中,需要支持自动驾驶,因此对车辆之间数据交互提出了更高的要求,如更高的吞吐量、更低的时延、更高的可靠性、更大的覆盖范围、更灵活的资源分配等。
当NR-V2X的终端工作在上述第二模式时(即NR-V2X中的模式2),终端根据侦听进行资源选取,具体的,当在时隙n有新的数据包到达,需要进行资源选取,终端会根据过去一段时间的侦听结果,在资源选择窗内进行资源选取。图2是终端在选择窗内进行资源选取的方式示意图。在图2所示的示例中,终端确定的资源侦听窗(简称侦听窗)为[n-1000,n-1),资源选择窗(简称选择窗)为[n+1,n+100]。
终端在选择窗内进行资源选取的简要过程如下:
1、终端将选择窗内所有可用的资源作为一个集合A,
2、如果终端在侦听窗内某些子帧没有侦听结果,则这些子帧在选择窗内对应的子帧上的资源被排除掉;
3、如果终端侦听窗内检测到物理侧行控制信道(PSCCH,Physical Sidelink Control Channel),测量该PSCCH的RSRP或者该PSCCH所调度的物理侧行共享信道(PSSCH,Physical Sidelink Shared Channel)的RSRP,如果测量的RSRP高于RSRP门限,并且根据该控制信息中预留信息确定的其预留的传输资源与本用户待发送的数据存在资源冲突,则用户在集合A中排除掉该资源。其中,RSRP门限的选取是由检测到的PSCCH中携带的优先级信息和终端待传输数据的优先级确定的。
4、如果集合A中剩余的资源个数小于总资源个数X%,终端会提升RSRP的门限3dB,并且重复上述步骤,直到集合A中剩余的资源个数大于总资源数的X%。其中,X是高层配置参数。
5、终端将集合A上报给高层。
高层根据物理层上报的可用资源集合,从中随机选取N个传输资源用于侧行传输。
在终端选择了传输资源之后,由于存在两个终端因选取相同的传输资源而发生资源冲突的可能,为了解决这个问题,在NR-V2X中引入了pre-emption和re-evaluation机制,使得终端在使用选取的资源之前可以判断是否跟其他终端存在资源冲突,如果没有冲突,可以继续使用选取的传输资源,如果有资源冲突,需要根据相应的机制进行避让和资源重选,以避免资源冲突。
在re-evaluation机制中,终端在完成资源选择后仍然持续侦听侧行控制信息,并对已选但未指示的资源进行至少一次的再次评估。图3是re-evaluation机制示意图。如图3所示,资源w、x、y、z、v是UE在时刻n已经选择的时频资源,资源x位于时隙m。对于UE即将在资源x发送侧行控制信息进行首次指示的资源y和z(资源x之前已经被资源w中的侧行控制信息指示)。UE至少在时隙m-T 3执行一次资源侦听,即确定资源选择窗与侦听窗,并对资源选择窗内的资源进行资源排除,得到候选资源集合。如果资源y或z不在候选资源集合中,则UE重选资源y和z中不在候选资源集合中的时频资源,也可以重选任何已经选择但未通过发送侧行控制信息指示的资源,例如资源y、z和v中的任意几个资源。上述m-T 3取决于终端的处理能力。
在NR-V2X中,关于pre-emption机制的结论都是以被抢占UE的角度描述的。在完成资源选择后,UE仍然持续侦听侧行控制信息,如果已经选择的并且已经通过发送侧行控制信息指示的时频资源满足以下三个条件,则触发资源重选:
1.侦听到的侧行控制信息中预留的资源与UE已选且已指示的资源重叠,包括全部重叠和部分重叠。
2.UE侦听到的侧行控制信息对应的PSCCH的RSRP或该PSCCH调度的PSSCH的RSRP大于SL RSRP门限。
3.侦听到的侧行链路控制信息(SCI,Sidelink Control Information)中携带的优先级比UE待发送数据的优先级高。
图4是pre-emption机制示意图。如图4所示,资源w、x、y、z、v是UE已经选择的时频资源,资源x位于时隙m。对于UE即将在时隙m发送侧行控制信息指示的且已经被UE之前发送的侧行控制信息指示的资源x和y。UE至少在时隙m-T 3执行一次资源侦听,确定候选资源集合。如果资源x或y不在候选资源集合中(满足上述条件1和2),进一步判断是否是由于携带高优先级的侧行链路控制信息的指示导致资源x或y不在候选资源集合中(满足上述条件3),如果是,则UE执行资源重选,重新选取x和y中满足上述3个条件的时频资源。
由于没有侦听能力的终端随机选择侧行资源,且不进行re-evaluation或pre-emption检测;而具有侦听能力的终端,选取了传输资源之后,在使用该资源进行侧行传输之前,需要进行re-evaluation或pre-emption检测,以判断是否和其他终端发生资源冲突。并且在发生冲突时,具有侦听能力的终端的优先级如果高于有冲突的终端,则该终端不会进行资源重选,而是期望与其有冲突的终端进行资源重选,这就导致没有侦听能力的终端只干扰高优先级的具有侦听能力的终端的侧行传输。
鉴于上述问题,本申请实施例提出一种设置方法,图5是根据本申请实施例的一种设置方法500的示意性流程图,该方法可选地可以应用于上述没有侦听能力的终端设备。该方法包括以下内容的至少部分内容:
S510:第一终端设备在发送侧行数据时,将调度该侧行数据的SCI中的优先级设置为第一优先级。
上述第一终端设备可以包括没有侦听能力的终端设备。
现有技术中,终端在发送侧行数据时,将该侧行数据的优先级承载在SCI中;本实施例中SCI中 携带的第一优先级与第一终端设备发送的侧行数据对应的优先级可以不同。
在一种实施方式中,上述第一优先级可以设置为最高优先级。
可选地,该最高优先级为第一终端设备进行侧行数据传输的资源池所允许的优先等级中的最高优先级,或者,该最高优先级为侧行数据对应的所有优先级中的最高优先级。
实施例1:
在本实施例中,没有侦听能力的终端在发送侧行数据时,将调度该侧行数据的SCI中的第一优先级设置为最高优先级。
当有侦听能力的终端进行pre-emption检测时,在满足如下条件的情况下,该终端会进行资源重选:
1.进行侦听的终端(TX UE)侦听到的其他终端(RX UE)的侧行控制信息中预留的资源与TX UE已选且已指示的资源重叠,包括全部重叠和部分重叠。
2.TX UE侦听到的RX UE的SCI对应的PSCCH的RSRP或该PSCCH调度的PSSCH的RSRP大于SL RSRP门限。
3.TX UE侦听到的RX UE的侧行控制信息中携带的第一优先级(记为P_rx)比TX UE待发送数据的优先级(记为P_tx)高,即P_rx<P_tx,其中P_rx和P_tx表示优先等级对应的值,该值越高,表示优先等级越低。例如,侧行数据对应的优先级包括8个等级,即[0,7],其中,优先等级值为0表示优先级最高,优先等级值为7表示优先级最低。
对于没有侦听能力的终端,其采用随机选取的方式获取传输资源,在使用传输资源进行侧行传输时,将SCI中的第一优先级设置为最高优先级,从而使得其他终端在进行pre-emption检测时,其优先等级低于或等于该终端的优先级,可以满足触发终端进行资源重选的条件之一。
可见,将没有侦听能力的终端的SCI中的第一优先级设置为最高级,使得其他有侦听能力的终端的优先级都低于(或等于)没有侦听能力的终端的优先级,在pre-emption检测机制中可以使得有侦听能力的终端更容易满足资源抢占的条件,触发资源重选,避免与没有侦听能力终端的资源冲突。
当有侦听能力的终端进行资源选取或进行re-evaluation检测时,如果终端在侦听窗内检测到PSCCH,就测量该PSCCH的RSRP或者该PSCCH所调度的PSSCH的RSRP,如果测量的RSRP高于RSRP门限、并且根据SCI中预留信息确定的其预留的传输资源与本终端待发送的数据存在资源冲突,则有侦听能力的终端在可用资源集合中排除掉该资源。其中,RSRP门限的选取是由检测到的PSCCH中携带的优先级信息和终端待传输数据的优先级确定的,优先级越高,对应的RSRP门限也越高。
可见,将没有侦听能力的终端的SCI中的第一优先级设置为最高级,使得确定出的RSRP门限最高,则有侦听能力的终端在侦听窗内检测到PSCCH后,测量该PSCCH的RSRP或者该PSCCH所调度的PSSCH的RSRP高于RSRP门限的可能性最小,则有侦听能力的终端在可用资源集合中排除掉该没有侦听能力的预留的传输资源的可能性最小。因此,无论具有侦听能力的终端的优先级如何,该终端都不容易触发资源重选,没有侦听能力的终端的传输可能与所有优先级的具有侦听能力的终端之间存在资源冲突,故而避免了没有侦听能力的终端只干扰高优先级的具有侦听能力的终端的侧行传输。
在另一种实施方式中,上述第一优先级可以设置为最低优先级。
可选地,该最低优先级为第一终端设备进行侧行数据传输的资源池所允许的优先等级中的最低优先级,或者,该最高优先级为侧行数据对应的所有优先级中的最低优先级。
实施例2:
在本实施例中,没有侦听能力的终端在发送侧行数据时,将调度该侧行数据的SCI中的第一优先级设置为最低优先级。
当有侦听能力的终端进行pre-emption检测时,与实施例1相同,在满足上述3个条件的情况下,该终端会进行资源重选。
对于没有侦听能力的终端,其采用随机选取的方式获取传输资源,在使用传输资源进行侧行传输时,将SCI中的第一优先级设置为最低优先级,从而使得其他终端在进行pre-emption检测时,其优先等级高于或等于该终端的优先级,不满足触发终端进行资源重选的条件之一。
可见,将没有侦听能力的终端的SCI中的第一优先级设置为最低级,使得其他有侦听能力的终端的优先级都高于(或等于)没有侦听能力的终端的优先级,在pre-emption检测机制中使得有侦听能力的终端不满足资源抢占的条件,不触发资源重选。因此,无论具有侦听能力的终端的优先级如何,该终端都不触发资源重选,没有侦听能力的终端的传输可能与所有优先级的具有侦听能力的终端之间存在资源冲突,故而避免了没有侦听能力的终端只干扰高优先级的具有侦听能力的终端的侧行传输。
当有侦听能力的终端进行资源选取或进行re-evaluation检测时,如果终端在侦听窗内检测到PSCCH,就测量该PSCCH的RSRP或者该PSCCH所调度的PSSCH的RSRP,如果测量的RSRP高于RSRP门限、并且根据SCI中预留信息确定的其预留的传输资源与本终端待发送的数据存在资源冲突, 则有侦听能力的终端在可用资源集合中排除掉该资源。其中,RSRP门限的选取是由检测到的PSCCH中携带的优先级信息和终端待传输数据的优先级确定的,优先级越高,对应的RSRP门限也越高。
可见,将没有侦听能力的终端的SCI中的第一优先级设置为最低级,使得确定出的RSRP门限最低,则有侦听能力的终端在侦听窗内检测到PSCCH后,测量该PSCCH的RSRP或者该PSCCH所调度的PSSCH的RSRP高于RSRP门限的可能性最大,则有侦听能力的终端在可用资源集合中排除掉该没有侦听能力的预留的传输资源的可能性最大。
在另一种实施方式中,上述第一优先级可以设置为不高于第一参数对应的优先级;或者,上述第一优先级的取值可以设置为大于或等于第一参数对应的优先级取值。
可选地,上述第一参数可以包括资源抢占使能(sl-PreemptionEnable)参数。sl-PreemptionEnable参数是在资源池配置信息中包括的参数,该参数用于指示该资源池中是否支持pre-emption检测。sl-PreemptionEnable参数的可能取值包括{enabled,pl1,pl2,pl3,pl4,pl5,pl6,pl7,pl8}。当该参数被配置为“enabled”时,进行侦听的终端判断根据实施例1和实施例2中的3个条件判断是否被资源抢占,以及是否需要进行资源选取。此时,可以按照实施例1的方式,即配置没有侦听能力的终端的第一优先级为最高优先级,从而使得在进行pre-emption检测时,侦听终端更容易满足被资源抢占的条件,并触发资源选取;或使得在进行资源选择或re-evaluation检测时,侦听终端不更容易满足被资源抢占的条件,不触发资源选取。或者,可以按照实施例2的方式,即配置没有侦听能力的终端的第一优先级为最低优先级,从而使得在进行pre-emption检测时,侦听终端不更容易满足被资源抢占的条件,不触发资源选取;或使得在进行资源选择或re-evaluation检测时,侦听终端更容易满足被资源抢占的条件,且触发资源选取。
实施例3:
在本实施例中,没有侦听能力的终端在发送侧行数据时,将调度该侧行数据的SCI中的第一优先级的取值设置为大于或等于sl-PreemptionEnable参数对应的优先级取值。
当sl-PreemptionEnable参数被配置为P_pre,即对应pl1至pl8中的一个值时,进行侦听的终端判断是否被资源抢占,以及是否需要进行资源选取,除了需要满足实施例1和实施例2中的3个条件外,还需要满足以下条件:
4.TX UE侦听到的RX UE的侧行控制信息中携带的优先级比参数sl-PreemptionEnable对应的优先级高,即P_rx<P_pre。
只有当上述4个条件都满足时,进行资源侦听的终端才会被其他终端资源抢占(pre-emption),并触发进行资源选取。
没有侦听能力的终端在发送侧行数据时,其SCI中的第一优先级设置为大于或等于P_pre的一个等级,即P_rx>=P_pre,即没有侦听能力的终端发送的侧行数据的优先级低,因此,进行侦听的终端不会被资源抢占,即无论进行侦听的终端的优先级是否低于没有侦听能力的终端的优先级,都不会被资源抢占,也就不会进行资源重选。即,所有进行资源侦听的终端即使检测到和没有侦听能力的终端选取的资源有资源冲突也不会进行资源重选。没有侦听能力的终端的传输可能与所有优先级的具有侦听能力的终端之间存在资源冲突,从而避免了只干扰优先级高的具有侦听能力的终端的传输。
可见,将没有侦听能力终端的第一优先级设置为不高于第一参数(例如sl-PreemptionEnable参数)配置的优先级门限,有侦听能力的终端在侦听时都不会被资源抢占,不会进行资源重选,使得没有侦听能力的终端可能与所有优先等级的有侦听能力的终端存在资源冲突,而避免只影响高优先级的具有侦听能力的终端的传输。
以上实施例1至3中,通过设置没有侦听能力的终端设备的第一优先级,实现了对所有优先级的具有侦听能力的终端的干扰情况相同。没有侦听能力的终端的传输可能与所有优先级的具有侦听能力的终端之间均存在资源冲突,或者与所有优先级的具有侦听能力的终端之间均不存在资源冲突,从而避免只影响高优先级的具有侦听能力的终端的传输。
本申请实施例还提出另一种设置方法,通过一定的设置来确定在进行资源选取或资源重选时没有侦听能力的终端设备对应的RSRP门限,避免只影响高优先级的具有侦听能力的终端的传输。
图6是根据本申请实施例的一种设置方法600的示意性流程图,该方法可选地可以应用于上述具有侦听能力的终端设备。该方法包括以下内容的至少部分内容:
S610:第二终端设备在进行资源选取、资源重选、re-evaluation检测或pre-emption检测时,根据第一配置参数确定第一终端设备对应的RSRP门限;其中,该第一终端设备包括没有侦听能力的终端设备。
上述第一配置参数可以由网络配置信息或预配置信息确定。
在一些实施方式中,上述第一配置参数可以包括优先级参数。
可选地,上述根据第一配置参数确定第一终端设备对应的RSRP门限,包括:
根据第一配置参数和第一终端设备的SCI中携带的优先级信息,确定RSRP门限;或者,
根据第一配置参数和第二终端设备的优先级信息,确定RSRP门限;或者,
根据第一配置参数、第一终端设备的SCI中携带的优先级信息及第二终端设备的优先级信息,确定RSRP门限。
在一些实施方式中,上述第一配置参数可以包括RSRP门限。
以下采用实施例4中的两个示例,分别介绍上述第一配置参数的两种示例。
实施例4:
具有侦听能力的终端在进行资源选择、资源选取、re-evaluation检测或pre-emption检测时,如果检测到没有侦听能力的终端时,对没有侦听能力的终端使用第一配置参数。
如果具有侦听能力的终端能够检测和识别没有侦听能力的终端,可以针对没有侦听能力的终端使用第一配置参数。
实施例4-1:
具有侦听能力的终端在侦听过程中,通过资源排除确定候选资源集合,在资源排除的过程中,如果检测到其他终端的SCI,根据其他终端的SCI中携带的优先级信息(记为P_rx)和该终端的优先级信息(记为P_tx)确定RSRP门限,如果测量其他终端的RSRP超过该RSRP门限,并且其他终端预留的传输资源和该终端在资源选择窗内的资源重叠,则从资源选择窗中排除该资源。在此过程中,如果检测到其他终端是没有侦听能力的终端,则该终端根据第一配置参数确定RSRP门限。
可选的,第一配置参数是优先级参数。进一步的,该终端根据该优先级参数、P_rx和P_tx确定RSRP门限,或者该终端根据该优先级参数和P_rx确定RSRP门限,或者该终端根据该优先级参数和P_tx确定RSRP门限,或者该终端只根据该优先级参数确定RSRP门限。
例如,网络配置P_tx、P_rx和RSRP门限的对应关系或表格,即根据P_tx和P_rx,结合该对应关系或表格可以确定相应的RSRP门限。通常,优先级越高,对应的RSRP门限也越高。
网络配置优先级参数,终端检测到没有侦听能力的终端时,根据该优先级参数和P_tx确定RSRP门限,网络可以配置该优先级参数对应的优先等级很低,例如,对应优先等级7(即最低优先级),从而使得确定的RSRP门限非常低,这样就很容易使得测量的没有侦听能力的终端的RSRP高于该门限,从资源选择窗内排除没有侦听能力的终端预留的资源,从而避免有侦听能力的终端与没有侦听能力的终端之间的传输冲突。
又例如,网络配置优先级参数,终端检测到没有侦听能力的终端时,根据该优先级参数和P_rx确定RSRP门限,这样,当有侦听能力的终端在进行资源排除时,都是用该优先级参数确定RSRP门限,而无论该终端对应的优先级是高还是低,从而使得没有侦听能力的终端对所有优先等级的具有侦听能力的终端的干扰概率是相同的,避免只干扰优先等级高的具有侦听能力的终端。进一步的,网络可以配置该优先级参数对应的优先等级很低,例如,对应优先等级7(即最低优先级),从而使得确定的RSRP门限非常低,这样就很容易使得测量的没有侦听能力的终端的RSRP高于该门限,从资源选择窗内排除没有侦听能力的终端预留的资源,从而避免有侦听能力的终端与没有侦听能力的终端之间的传输冲突。
又例如,网络配置优先级参数,终端检测到没有侦听能力的终端时,根据该优先级参数确定RSRP门限,这样,当有侦听能力的终端在进行资源排除时确定的RSRP门限相同,而无论该终端对应的优先级是高还是低,从而使得没有侦听能力的终端对所有优先等级的具有侦听能力的终端的干扰概率是相同的,避免只干扰优先等级高的具有侦听能力的终端。进一步的,网络可以配置该优先级参数对应的优先等级很低,例如,对应优先等级7(即最低优先级),从而使得确定的RSRP门限非常低,这样就很容易使得测量的没有侦听能力的终端的RSRP高于该门限,从资源选择窗内排除没有侦听能力的终端预留的资源,从而避免有侦听能力的终端与没有侦听能力的终端之间的传输冲突。
又例如,网络配置优先级参数,终端检测到没有侦听能力的终端时,根据该优先级参数、P_tx和P_rx确定RSRP门限,网络可以配置该优先级参数对应的优先等级很低,例如,对应优先等级7(即最低优先级),从而使得确定的RSRP门限非常低,这样就很容易使得测量的没有侦听能力的终端的RSRP高于该门限,从资源选择窗内排除没有侦听能力的终端预留的资源,从而避免有侦听能力的终端与没有侦听能力的终端之间的传输冲突。
实施例4-2:
在本例中,上述第一配置参数是RSRP门限。
具有侦听能力的终端在侦听过程中,通过资源排除确定候选资源集合,在资源排除的过程中,如果检测到没有侦听能力的终端发送的SCI,则使用该第一配置参数,即RSRP门限,进行资源排除,即该终端测量没有侦听能力的终端的RSRP,如果超过该RSRP门限,则将没有侦听能力的终端预留的传输资源从资源选择窗内排除。
可见,由于所有优先级的具有侦听能力的终端采用的RSRP门限相同,没有侦听能力的终端对所有 优先等级的具有侦听能力的终端的干扰概率是相同的,避免了只干扰优先等级高的具有侦听能力的终端。
进一步地,还可以将RSRP门限设置非常低,这样就很容易使得测量的没有侦听能力的终端的RSRP高于该门限,从资源选择窗内排除没有侦听能力的终端预留的资源,从而避免有侦听能力的终端与没有侦听能力的终端之间的传输冲突。
在本实施例中,前提条件是能够识别出没有侦听能力的终端。上述步骤S610之前可以进一步包括:第二终端设备确定第一终端设备是没有侦听能力的终端设备。
可选地,上述第二终端设备采用以下至少一种方式,确定第一终端设备是没有侦听能力的终端设备:
方式一:第二终端设备根据第一终端设备的SCI中的信息域,确定第一终端设备是没有侦听能力的终端设备;
例如,在SCI中包括1比特信息域,该比特取值为1时表示是没有侦听能力的终端,取值为0时表示具有侦听能力的终端。
其中,上述第一终端设备的SCI可以是第一阶SCI和/或第二阶SCI。
方式二:第二终端设备根据第一终端设备的SCI的格式,确定第一终端设备是没有侦听能力的终端设备。
例如,上述SCI的格式包括第一格式和第二格式;
其中,第一格式包括可以第一阶SCI格式(format)1-A、第二阶SCI格式2-A和第二阶SCI格式2-B中的至少一项。
方式三:第二终端设备根据加扰第一终端设备的SCI比特序列的扰码序列,确定第一终端设备是没有侦听能力的终端设备;
例如,SCI的信息比特序列,或经过信道编码后的比特序列可以进行加扰处理,如果使用第一序列进行加扰,则表示具有侦听能力的终端,如果使用第二序列进行加扰,则表示没有侦听能力的终端。
方式四:第二终端设备根据第一终端设备的PSCCH或PSSCH的DMRS序列,确定第一终端设备是没有侦听能力的终端设备;
例如,如果PSCCH或PSSCH的DMRS序列采用第一序列,则表示是具有侦听能力的终端,如果采用第二序列,则表示没有侦听能力的终端。
方式五:第二终端设备在资源池中配置的第一时频资源集合内检测到第一终端设备的PSCCH时,确定第一终端设备是没有侦听能力的终端设备。
这种方式下,可以在资源池中配置第一时频资源集合,并配置没有侦听能力的终端在该第一时频资源集合内进行传输。相应的,当其他终端在该第一时频资源集合内检测到PSCCH(即SCI)时,即可确定发送该PSCCH的终端是没有侦听能力的终端。
本申请实施例还提出一种侧行数据传输方法,图7是根据本申请实施例的一种侧行数据传输方法700的示意性流程图,该方法可选地可以应用于上述具有侦听能力的终端设备和不具有侦听能力的终端设备。该方法包括以下内容的至少部分内容:
S710:终端设备获取资源池配置信息,根据第一优先级门限,确定在资源池中传输优先级不高于该第一优先级门限对应的优先级的侧行数据。
可选地,上述资源池配置信息中包括该第一优先级门限。
可选地,上述资源池配置信息中可以包括指示信息,该指示信息用于指示没有侦听能力的终端允许在该资源池中进行数据传输。
以下实施例5对应这种侧行数据传输方式。
实施例5:
当资源池中允许随机资源选取时,该资源池配置信息中包括第一优先级门限,优先级高于该第一优先级门限的侧行数据不允许在该资源池中进行传输。
当资源池允许有侦听能力的终端(通过侦听选取传输资源)和没有侦听能力的终端(通过随机选取获取传输资源)共同使用时,没有侦听能力的终端选取了传输资源,由于不会进行re-evaluation和pre-emption检测,也就不会进行资源重选,只能期望其他有侦听能力的终端通过re-evaluation或pre-emption检测避免与没有侦听能力的终端之间的干扰,而当有侦听能力的终端的优先级高于没有侦听能力的终端时,也不会触发资源重选,从而导致没有侦听能力的终端与高优先级的具有侦听能力终端之间的干扰。因此,本申请实施例在资源池配置信息中,配置了第一优先级门限,优先级高于该第一优先级门限的侧行数据不允许在该资源池中传输,从而可以避免没有侦听能力的终端对高优先级侧行传输的干扰。
例如,侧行数据的优先级为8个等级,即[0,7],其中0表示最高优先级,7表示最低优先级,在资 源池配置信息中配置第一优先级门限为P_thd=3,则优先等级为0,1,2的侧行数据(其对应的优先级比第一优先级门限对应的优先级高)不允许在该资源池中传输,即该资源池能够支持的侧行数据的优先级为[3,7],这样就避免了没有侦听能力的终端对优先级为0,1,2的侧行数据的干扰。
本申请实施例还提出一种侧行数据传输方法,图8是根据本申请实施例的一种侧行数据传输方法800的示意性流程图,该方法可选地可以应用于上述具有侦听能力的终端设备。该方法包括以下内容的至少部分内容:
S810:在信道占用率(CBR,Channel Busy Ratio)低于第一门限的情况下,第二终端设备检测到与第一终端设备发生资源冲突时,第二终端设备进行资源重选;其中,第一终端设备包括没有侦听能力的终端设备。第二终端设备包括有侦听能力的终端设备。
可选地,第二终端设备检测到与第一终端设备发生资源冲突,并且第二终端设备测量第一终端设备的RSRP高于第二门限时,第二终端设备进行资源重选。
可选地,上述第一门限和第二门限根据网络配置信息或预配置信息确定。
在本实施例中,前提条件是能够识别出没有侦听能力的终端。上述步骤S810之前可以进一步包括:第二终端设备确定第一终端设备是没有侦听能力的终端设备。具体的识别方式与上述实施例4中的方式类似,在此不再赘述。
以下实施例6对应这种侧行数据传输方式。
实施例6:
如果CBR低于第一门限,则当具有侦听能力的终端检测到与没有侦听能力的终端发生资源冲突时,有侦听能力的终端进行资源选取,以避免和没有侦听能力的终端之间的干扰。
或者,如果CBR低于第一门限,则当具有侦听能力的终端检测到与没有侦听能力的终端发生资源冲突、并且具有侦听能力的终端测量没有侦听能力的终端的RSRP高于第二门限时,有侦听能力的终端进行资源选取,以避免和没有侦听能力的终端之间的干扰。
上述第一门限和第二门限可以根据网络配置信息或预配置信息确定。
当终端测量的CBR低于该第一门限时,可以认为系统资源是空闲的。此时终端检测到存在资源冲突,可以触发该终端进行资源重选;由于系统空闲,因此在资源重选的过程中选取到空闲资源的概率大,从而可以避免终端之间的干扰。
本申请实施例还提出一种配置方法,图9是根据本申请实施例的一种配置方法900的示意性流程图,该方法可选地可以应用于网络设备。该方法包括以下内容的至少部分内容:
S910:网络设备向第二终端设备发送配置信息,该配置信息用于确定第一配置参数,该第一配置参数用于该第二终端设备在进行资源选取、资源重选、re-evaluation检测或pre-emption检测时确定第一终端设备对应的RSRP门限;其中,
