Specifically: the terminal itself determines a candidate reservation resource set consisting of at least Y subframes, the physical layer determines the sensing period P step , and the upper layer configures a candidate sensing interval sequence for the physical layer, that is, a sequence consisting of 0 and 1. The length of is 10 bits, and each bit corresponds to a sensing period.

技术领域
本公开涉及移动通信技术领域,具体涉及一种直通链路资源的部分感知方法及设备。
背景技术
第五代移动通信系统(5th Generation Mobile Communication Technology,5G)新空口(New Radio,NR)智能网联汽车(Vehicle-to-Everything,V2X)系统中,终端之间使用直通链路(Sidelink)进行通信,数据通信所使用的时频资源,相关标准支持两种资源分配模式对其进行调度,第一种是模式1(Mode1)资源分配模式,由基站统一调度终端通信所需的时频资源,第二种是模式2(Mode2)资源分配模式,是在没有基站参与的情况下,终端自主选择通信所需的时频资源。
其中,Mode 2资源分配模式由于没有基站统一调度,终端/用户设备(User Equipment,UE)可通过资源感知机制确定其它UE的资源占用情况,并根据资源感知结果进行资源选择,从而降低碰撞概率,增强传输鲁棒性。
在第四代移动通信系统(4th Generation Mobile Communication Technology,4G)长期演进型(Long Time Evolution,LTE)的V2X标准中,针对电能利用效率(Power Usage Effectiveness,PUE)的节能需求,支持部分感知机制,终端可间断的进行感知,从而达到节电的目的。目前部分感知技术目前只在LTE中应用,PUE根据节能需求应用部分感知操作。NR的V2X标准还不支持部分感知。另外,现在的NR标准中只支持持续感知,没有针对PUE的节能感知机制,LTE中的部分感知操作只考虑周期传输,没有重评估机制,且针对一次业务发送进行的部分感知操作的配置只有一种,无法根 据周期和非周期传输的影响灵活配置。

为了帮助理解本公开,下面对本公开中可能涉及的一些概念进行简单说明:
部分感知:部分感知的基本原理是终端周期的感知预先选出来的资源集,最终从资源集中选出可用的资源。具体是:终端自身决定由至少Y个子帧组成的候选预约资源集,物理层确定感知的周期P step,高层为物理层配置一个候选感知间隔序列,即一串由0和1组成的序列,长度为10位,每位对应一个感知周期,当序列中的位对应的值是1的时候,终端在距候选预约资源集k×P step的时刻进行感知,并排除不可用的资源,最终从Y个子帧中选出可用的子帧,其中k是序列当前的位对应的索引值。图1给出了部分感知的一个示意图,其中,填充有小圆点的矩形框标识与序列中值为1的位对应的感知周期,虚线矩形框则表示与序列中值为0.的位对应的感知周期。
在Sidelink通信中,LTE仅包含周期传输,资源池中配置了资源预约间隔和感知周期两个变量,终端通过将两个变量相乘得到传输的周期,使用感知周期一个变量进行部分感知;NR则包含周期传输和非周期传输,资源池中 配置了资源预约周期这一变量,相关标准只支持持续感知,所以没有感知周期这一变量,终端通过资源预约周期进行业务初重传的周期性发送,终端进行非周期传输时不使用该变量,仅进行一次初重传操作。
相关NR标准中mode2资源分配重评估机制是终端在m-T3时刻(m是初传资源的发送时刻,T3是发送处理时延),利用业务到达并选择资源的时刻n和m时刻之间的持续感知结果,判断在这段时间之内是否有其他终端传输预约的资源与其在n时刻选出的资源会产生碰撞,排除会碰撞的资源,并重新选择。图2给出了重评估的一个示意图。
相关NR中的非连续接收(Discontinue Reception,DRX)机制主要是为了适当减少物理下行控制信道(Physical Downlink Control Channel,PDCCH)的监听,以达到节电的目的,主要操作是在激活状态(DRX on duration)下接收PDCCH,在非激活状态(DRX inactive duration)下不接收PDCCH。Sidelink可能在后续版本的节电机制中引入DRX。
如前文所述的,相关的NR标准中只在初传之前进行重评估操作,重传之前没有进行重评估操作,重评估部分使用的是通过持续感知获取到的结果,如果出于节能目的将LTE标准中的部分感知操作应用到NR标准的重评估操作的感知部分中,对于非周期传输的感知的可靠性可能会降低。
目前NR的V2X标准还不支持部分感知。如果在NR的V2X系统中如果出于节能目的引入部分感知机制,并沿用在LTE中类似的配置方式,即一个发送资源池配置一套部分感知配置参数,终端会在一次或多次业务发送进行的部分感知过程中都使用同一套部分感知配置。然而在不同时刻,周期传输和非周期传输对资源选择可靠性的影响不同,在资源选择触发的一个传输周期之前,可较有效的感知其他终端的周期传输,出于节能目的配置的感知密度可以较低,在资源选择触发前后一个传输周期内,业务初传之前,资源选择有可能受到其他终端非周期传输重传的影响,如果按照和之前相同的密度较低的感知配置进行感知,能够感知到的非周期业务会非常有限,选出的资源或重评估结果的可靠性会降低。
本公开实施例提供了一种部分感知的方法,能够支持不同的部分感知操作的配置参数,从而能够提高部分感知操作的灵活性。例如,可以根据不同 的时刻使用不同的部分感知配置参数。具体的,本公开实施例可以按照感知密度的高低配置多套部分感知配置参数,终端根据实现或(预)配置决定使用一套或多套部分感知配置参数,从而可以根据需要选择合适的部分感知配置参数,有利于终端节能,并提高部分感知的的鲁棒性。
请参照图3,本公开实施例提供的直通链路资源的部分感知的方法,由终端执行,具体包括:
步骤31,终端从至少两套不同的部分感知配置参数中,确定出至少一套部分感知配置参数。
这里,终端侧预先获得一个发送资源池所配置的至少两套部分部分感知配置参数,每套部分感知配置参数具有不同的参数,例如,各套部分感知配置参数具有不同的感知密度。每套部分感知配置参数通常包括以下参数:最少候选资源数量和候选感知间隔的比特序列。上述比特序列通常为某个预设长度,如10个比特位,每个比特位对应一个感知周期,当比特位的值是1的时候,表示在距离预约资源集k×P step的时刻进行感知,并排除不可用的资源,最终从Y个子帧中选出可用的子帧,其中k是比特位对应的索引值,P step为感知周期,Y为所述最少候选资源数量。
另外,本公开实施例可以预先在终端本地存储所述至少两套部分部分感知配置参数,或者终端接收网络发送的配置信息,获得所述至少两套部分部分感知配置参数。
步骤32,所述终端使用所述至少一套部分感知配置参数进行部分感知。
这里,终端根据步骤31中确定出的部分感知配置参数进行直通链路资源的部分感知。具体感知方式可以参考相关技术,本公开实施例对此不再赘述。
通过以上步骤,本公开实施例提供了多套部分感知配置参数,能够支持终端使用不同的部分感知操作的配置参数进行感知,例如,可以根据不同的时刻使用不同的部分感知配置参数,从而能够提高部分感知操作的灵活性。
在上述步骤32之后,所述终端还可以根据部分感知获得的感知结果,进行数据的初传和/或重传。所述重传可以包括一次或多次重传,分别对应一个或多个重传资源。
作为一种实现方式,本公开实施例中,按照感知密度的高低配置所述至 少两套部分感知配置参数。在上述步骤31中,所述终端确定出的至少一套部分感知配置参数为两套部分感知配置参数,分别是第一套配置参数和第二套配置参数,其中,第一套配置参数和第二套配置参数的感知密度不同。这里,假设第一套配置参数的感知密度小于第二套配置参数的感知密度,即,第一套配置参数的候选感知间隔的比特序列中值为1的比特位数,要少于第二套配置参数的候选感知间隔的比特序列中值为1的比特位数。这样,在上述步骤32中,所述终端使用第一套配置参数和第二套配置参数进行部分感知。具体的,可以是:
1)所述终端在处于DRX的DRX on duration下时,使用所述第一套配置参数进行部分感知,以及,在处于DRX的DRX inactive duration下时,使用所述第二套配置参数进行部分感知。即,终端在不同的DRX状态下使用不同的配置参数进行部分感知,每种DRX状态对应的配置参数不同。
例如,所述终端在从感知开始时刻到资源选择时刻的期间,当处于DRX的DRX on duration下时,使用所述第一套配置参数进行部分感知,以及,当处于DRX的DRX inactive duration下时,使用所述第二套配置参数进行部分感知。
又例如,所述终端在从感知开始时刻到数据初传时刻的期间,当处于DRX的DRX on duration下时,使用所述第一套配置参数进行部分感知,以及,当处于DRX的DRX inactive duration下时,使用所述第二套配置参数进行部分感知;
再例如,所述终端在从感知开始时刻到最后一次数据重传时刻的期间,当处于DRX的DRX on duration下时,使用所述第一套配置参数进行部分感知,以及,当处于DRX的DRX inactive duration下时,使用所述第二套配置参数进行部分感知。
2)所述终端在从感知开始时刻到数据初传时刻的期间,使用所述第一套配置参数和第二套配置参数进行部分感知。
例如,所述终端在从感知开始时刻到资源选择时刻的期间,使用所述第一套配置参数进行部分感知,以及,在从资源选择时刻到数据初传时刻的期间,使用所述第二套配置参数进行部分感知。
又例如,所述终端在从感知开始时刻到第一时刻的期间,使用所述第一套配置参数进行部分感知,以及,在从所述第一时刻到数据初传时刻的期间,使用所述第二套配置参数进行部分感知,其中,所述第一时刻位于数据初传时刻之前,且与所述数据初传时刻之间间隔第一预设时长f1。考虑到当前周期传输和非周期传输的特点,这里第一预设时长f1可以为31个时隙。
3)所述终端在从感知开始时刻到数据重传时刻的期间,使用所述第一套配置参数和第二套配置参数进行部分感知。
例如,所述终端在从感知开始时刻到资源选择时刻的期间,使用所述第一套配置参数进行部分感知,以及,在从资源选择时刻到数据重传时刻的期间,使用所述第二套配置参数进行部分感知。
又例如,所述终端在从感知开始时刻到第二时刻的期间,使用所述第一套配置参数进行部分感知,以及,在从所述第二时刻到最后一次数据重传时刻的期间,使用所述第二套配置参数进行部分感知,其中,所述第二时刻位于数据初传时刻之前,且与所述数据初传时刻之间间隔第二预设时长f2。考虑到当前周期传输和非周期传输的特点,这里第二预设时长f2可以为31个时隙。
从以上所述可以看出,本公开实施例针对一个发送资源池配置了多套部分感知配置参数,终端在不同时刻,可以根据周期和非周期传输对资源选择可靠性的影响不同,使用不同配置参数进行后续一段时间的部分感知操作,例如,在监测周期性传输的时间段内,使用第一套部分感知配置参数进行密度较低的部分感知操作,以确保节能效果;在监测非周期传输的时间段内,使用第二套部分感知配置参数进行短时间的高密度部分感知操作,确保感知结果的可靠性,减少传输碰撞。另外,在使用DRX进行节电的情况下,本公开实施例可以使用两套配置参数进行部分感知,在达到节电效果的情况下,还能适当减少资源碰撞。
作为一种实现方式,本公开实施例中,按照感知密度的高低配置所述至少两套部分感知配置参数。在上述步骤31中,所述终端确定出的至少一套部分感知配置参数为一套部分感知配置参数,具体可以是第一套配置参数或第二套配置参数。这样,在上述步骤32中,所述终端使用第一套配置参数或第 二套配置参数进行部分感知。所述第一套配置参数和第二套配置参数的感知密度不同。这里,假设第一套配置参数的感知密度小于第二套配置参数的感知密度。具体的,使用第一套配置参数或第二套配置参数进行部分感知可以是:
1)所述终端在从感知开始时刻到数据初传时刻的期间,使用所述第一套配置参数或第二套配置参数进行部分感知。
例如,所述终端在从感知开始时刻到资源选择时刻的期间,使用所述第一套配置参数进行部分感知,以及,在从资源选择时刻到数据初传时刻的期间,继续使用所述第一套配置参数进行部分感知。或者,所述终端在从感知开始时刻到资源选择时刻的期间,使用所述第二套配置参数进行部分感知,以及,在从资源选择时刻到数据初传时刻的期间,继续使用所述第二套配置参数进行部分感知。
又例如,所述终端在从感知开始时刻到第三时刻的期间,使用所述第一套配置参数进行部分感知,以及,在从所述第三时刻到数据初传时刻的期间,继续使用所述第一套配置参数进行部分感知,其中,所述第三时刻位于数据初传时刻之前,且与所述数据初传时刻之间间隔第三预设时长f3。或者,所述终端在从感知开始时刻到第三时刻的期间,使用所述第二套配置参数进行部分感知,以及,在从所述第三时刻到数据初传时刻的期间,继续使用所述第二套配置参数进行部分感知,其中,所述第三时刻位于数据初传时刻之前,且与所述数据初传时刻之间间隔第三预设时长f3。
考虑到当前周期传输和非周期传输的特点,这里第三预设时长f3可以为31个时隙。
2)所述终端在从感知开始时刻到数据重传时刻的期间,使用所述第一套配置参数或第二套配置参数进行部分感知。
例如,所述终端在从感知开始时刻到资源选择时刻的期间,使用所述第一套配置参数进行部分感知,以及,在从资源选择时刻到最后一次数据重传时刻的期间,继续使用所述第一套配置参数进行部分感知。或者,所述终端在从感知开始时刻到资源选择时刻的期间,使用所述第二套配置参数进行部分感知,以及,在从资源选择时刻到最后一次数据重传时刻的期间,继续使 用所述第二套配置参数进行部分感知。
又例如,所述终端在从感知开始时刻到第四时刻的期间,使用所述第一套配置参数进行部分感知,以及,在从所述第四时刻到最后一次数据重传时刻的期间,继续使用所述第一套配置参数进行部分感知。或者,所述终端在从感知开始时刻到第四时刻的期间,使用所述第二套配置参数进行部分感知,以及,在从所述第四时刻到最后一次数据重传时刻的期间,继续使用所述第二套配置参数进行部分感知,其中,所述第四时刻位于数据初传时刻之前,且与所述数据初传时刻之间间隔第四预设时长f4。其中,所述第四时刻位于数据初传时刻之前,且与所述数据初传时刻之间间隔第四预设时长f4。考虑到当前周期传输和非周期传输的特点,这里的第四预设时长f4可以为31个时隙。
以下通过多个示例对本公开实施例的方法作进一步的说明。以下示例包括使用两套配置参数进行部分感知,具体又分为:
