技术领域
本公开涉及终端技术领域,尤其涉及一种信息处理方法、装置及终端。
背景技术
在第五代(5 th Generation,5G)新无线接入技术(New Radio,NR)车联网(vehicle-to-everything,V2X)系统中,终端与终端之间在直通链路(Sidelink)上进行直接通信。在进行业务数据传输之前,首先需要确定直通链路数据传输所使用的时频资源,而确定时频资源的主要准则是避免不同终端所使用的时频资源之间的碰撞,以避免产生互相干扰。在NR V2X中,有两种资源调度模式,第一种是Mode(模式)1资源分配模式,由基站统一调度终端与终端之间在直通链路通信中所使用的时频资源,第二种是Mode2资源分配模式,是在没有基站参与的情况下,终端自主选择终端与终端之间在直通链路通信中所使用的时频资源。
NR-V2X Mode 2采用分布式资源调度,由于没有基站统一调度,终端(user equpment,UE)需通过资源感知机制确定其他UE的资源占用情况,并根据资源感知结果进行资源选择。相比于完全随机的资源选择机制,通过资源感知机制可以提高资源利用率,降低碰撞概率,提升系统性能。
但是,在相关技术中,资源感知过程是一直进行的,也就是说,即使终端没有数据发送,终端也需要持续不断的进行感知。如果参与直通链路通信的终端都是汽车的话,持续的资源感知所带来的耗电量还可以接受,但是,在直通链路通信系统中,除了汽车终端之外,还有一些对于电量消耗敏感的行人终端(pedestrian UE,PUE)或其他便携式移动终端。对于行人终端(PUE)而言,由于PUE的电池电量有限,持续不断的资源感知就会导致PUE的电 池电量迅速耗尽,影响了参与直通链路通信的PUE的用户体验和可用性。
发明内容

本公开实施例涉及的终端,可以是指向用户提供语音和/或数据连通性的设备,具有无线连接功能的手持式设备、或连接到无线调制解调器的其他处理设备等。在不同的系统中,终端的名称可能也不相同,例如在5G系统中,终端可以称为用户设备(User Equipment,UE)。无线终端可以经无线接入网(Radio Access Network,RAN)与一个或多个核心网(Core Network,CN)进行通信,无线终端可以是移动终端设备,如移动电话(或称为“蜂窝”电话)和具有移动终端设备的计算机,例如,可以是便携式、袖珍式、手持式、计算机内置的或者车载的移动装置,它们与无线接入网交换语言和/或数据。例如,个人通信业务(Personal Communication Service,PCS)电话、无绳电话、会话发起协议(Session Initiated Protocol,SIP)话机、无线本地环路(Wireless Local Loop,WLL)站、个人数字助理(Personal Digital Assistant,PDA)等设备。无线终端设备也可以称为系统、订户单元(subscriber unit)、订户站(subscriber station),移动站(mobile station)、移动台(mobile)、远程站(remote station)、接入点(access point)、远程终端设备(remote terminal)、接入终端设备(access terminal)、用户终端设备(user terminal)、用户代理(user agent)、用户装置(user device),本公开实施例中并不限定。

下面首先对本公开实施例提供的方案涉及的内容进行介绍。
1.NR-V2X直通链路Mode2资源分配的步骤包括:
(1)资源感知:资源感知是指终端根据某资源上接收信号的参考信号接收功率(reference signal received power,RSRP)强度来判断该资源是否被其他终端使用。在资源感知过程中,需要考虑NR V2X应用中的混合业务场景中周期性业务和非周期性业务的不同特点,以及业务类型对资源感知结果的影响。同时还需要根据物理信道中的时频资源粒度,资源池设置等信息进行合适的资源感知配置。资源感知窗是指终端进行资源感知的时间窗口。
(2)资源排除:资源排除的主要目的是根据感知的结果,排除资源选择窗内不可用于资源选择的资源,比如排除终端接收数据所需要占用的时频资源(NR V2X终端以半双工方式进行数据收发,半双工意味着终端不能同时收发数据),形成候选资源集合,降低资源碰撞概率,提高可靠性。
(3)资源选择:资源选择机制是在候选资源集合中为待发送业务包传输 块(transport block,TB)选择合适的发送时频资源,需要考虑业务的优先级、时延、业务包大小、以及传输可靠性要求进行资源选择。资源选择窗是指终端进行资源选择的时间窗口。
2.NR-V2X Mode 2采用分布式资源调度,由于没有基站统一调度,UE需通过资源感知机制确定其他UE的资源占用情况,并根据资源感知结果进行资源选择。相比于完全随机的资源选择机制,通过资源感知机制可以提高资源利用率,降低碰撞概率,提升系统性能。
当业务到达,终端在资源感知窗内接收数据包并解码直通链路控制信息(sidelink control information,SCI),落在资源选择窗内且RSRP大于RSRP门限值的资源需要被排除,剩余的资源是候选资源,然后从接收信号强度指示(Received Signal Strength Indication,RSSI)最小的20%的候选资源中随机选择或者直接从所有的候选资源随机选择直通链路传输所需资源。其中资源选择窗口的长度可以配置为业务的最大周期。
3.终端在直通链路上数据发送之前,首先进行资源感知并且根据资源感知的结果进行资源选择,该机制可以在一定程度上避免碰撞。相关技术中,如图2所示,为了获得尽可能准确的资源感知的结果,终端需要持续不断的进行资源感知,但这样同时会带来终端耗电量的显著增加。
基于以上,本公开实施例提供了一种信息处理方法、装置及终端,用以解决相关技术中资源感知方案耗电量大的问题。
其中,方法、装置及终端是基于同一申请构思的,由于方法、装置及终端解决问题的原理相似,因此方法、装置及终端的实施可以相互参见,重复之处不再赘述。

其中,多级序列具体可为相同序列的嵌套。
四、PSCCH监听降低节能方案以及与SL DRX(直通链路不连续接收)的关系:
(9)当直通链路上配置了周期性SL DRX时,第一节能信号S-WUS指示第一终端在S-WUS所关联的SL DRX周期内开始进行PSCCH监听、开始进行资源感知以及开始进行资源选择等至少一项操作;或者,第一节能信号S-WUS指示第一终端停止进行PSCCH监听、停止进行资源感知以及开始进行资源选择等至少一项操作;关于上述“开始”执行的操作具体可以是在周期开始时“开始”执行操作。

(11)第一节能信号S-WUS的上述指示是通过如下两种方法之一进行:
1)方法1:第一节能信号S-WUS中包含有使得第一终端被唤醒或休眠的信息;
2)方法2:第一节能信号S-WUS如果出现的话,就指示第一终端被唤醒,如果不出现的话,就指示第一终端被休眠。
五、第一节能信号S-WUS的波束发送方式:
(12)在频率范围(frequency range,FR)1(即上述第一频率范围),第一节能信号S-WUS采用符号重复的方式进行发送,即:使用至少两个正交频分复用(Orthogonal frequency division multiplex,OFDM)符号发送相同的S-WUS序列。
(13)在FR2(即上述第二频率范围),第一节能信号S-WUS采用波束扫描的方式进行发送,即:使用至少两个OFDM符号发送具有不同波束方向的S-WUS序列。具体的,一个OFDM符号占用一个波束,发送一个序列;多个波束上的序列相同。
其中,FR1具体可为410MHz~7125MHz,FR2具体可为24250MHz~52600MHz。
下面对本公开实施例提供的方案进行具体举例说明。
举例1(第一节能信号S-WUS的序列设计1):

而上述第一节能信号S-WUS的序列可采用第一序列,如下所示:
d S-WUS(n)=[1-2x 0((n+m 0)mod 132)][1-2x 1((n+m 1)mod 132)];

本举例采用这种第一序列的设计方法,可以依据该方法产生基于序列的第一节能信号S-WUS,从而可以指示第一终端被唤醒或休眠。序列生成比较简洁,复杂度较低。
举例2(第一节能信号S-WUS的序列设计2):
本方案提供一种适用于直通链路的基于序列的第一节能信号S-WUS的 发送方法:采用基于序列的直通链路第一节能信号S-WUS,指示第一终端在直通链路通信中被唤醒或休眠。而上述的被唤醒是指第一终端监听PSCCH、开始进行资源感知以及开始进行资源选择等至少一项操作;被休眠是指第一终端停止监听PSCCH、停止进行资源感知以及停止进行资源选择等至少一项操作。

定义为长度为31的Gold序列c(n)。c(n)的长度为M PN,其中n=0,1,...,M PN-1。c(n)的定义如下:
c(n)=(x 1(n+N c)+x 2(n+N c))mod2;
x 1(n+31)=(x 1(n+3)+x 1(n))mod2;

Figure PCTCN2021105997-appb-000202
并且
Figure PCTCN2021105997-appb-000203
本举例采用这种第二序列的设计方法,可以依据该方法产生基于序列的第一节能信号S-WUS,从而可以指示第一终端被唤醒或休眠。序列生成数量较多适用于终端数量较多的场景。
举例3(第一节能信号S-WUS指示方式):
本方案提供一种适用于直通链路的基于序列的第一节能信号S-WUS的发送方法:采用基于序列的直通链路第一节能信号S-WUS,指示第一终端在直通链路通信中被唤醒或休眠。而上述的被唤醒是指第一终端开始监听PSCCH、开始进行资源感知以及开始进行资源选择等至少一项操作;被休眠是指第一终端停止监听PSCCH、停止进行资源感知以及停止进行资源选择等至少一项操作。
其中,(1)第一节能信号S-WUS可以被配置用来指示以下至少一种唤醒或休眠方式:
1)终端特定(UE-specific):一次S-WUS信号发送仅唤醒或休眠一个UE;
2)小区特定唤醒或休眠(Cell-specific):一次S-WUS信号发送唤醒或休眠同一小区内覆盖内所有UE;
3)终端组特定(UE-Group-specific):一次S-WUS信号发送唤醒或休眠一组UE;
4)直通链路识别号特定(SL-SSID-specific):一次S-WUS信号发送唤醒或休眠具有相同SL-SSID的所有UE。
(2)根据业务信道的传输类型,第一节能信号S-WUS可以被配置如下至少一种发送方法:
1)当传输类型是单播(Unicast)时:采用UE-specific的S-WUS信号发送方式;
2)当传输类型是广播(Broadcast)时:采用Cell-specific或SL-SSID-specific的S-WUS信号发送方式;
3)当传输类型是组播(Groupcast)时:采用UE-group-specific或SL-SSID-specific的S-WUS信号发送方式。
如果一次S-WUS信号发送只能唤醒或休眠一个UE,意味着S-WUS信号可以是UE-specific的方式进行指示,这种指示方法指示的粒度很小,可以指示单个UE是否被唤醒或休眠,这样可以仅仅唤醒有业务需求的终端,节能效果较好。
而SL-SSID-specific的指示方法,一次S-WUS信号可以唤醒具有相同SL-SSID的所有终端,也就是位于同一个同步簇内的所有终端,让这些终端开始监听PSCCH或开始进行资源感知,这种指示方法指示的粒度较大,适用于广播业务或组播业务,开销较小,并且不容易产生终端之间S-WUS信号的干扰。
本举例中,UE-specific或UE-group-specific的指示方式,节能效果较好;SL-SSID-specific或Cell-specific的指示方法,开销较小,并且不容易产生终端之间S-WUS信号的干扰。
举例4(单级序列或多级序列的第一节能信号S-WUS):
本方案中第一节能信号S-WUS可以采取单级序列或多级序列(具体可为两级序列)。
具体的,可根据场景选择不同的序列类型:
(1)当Cell-specific或SSID-specific时:采用单级序列;
(2)当UE-specific或Group-specific时:采用多级序列;
这样做的好处是为了能够提供更多的可用序列,一般地,当S-WUS采取单级序列时,一般可以支持数百个序列(例如:256个);而采用两级序列就可以支持256×256个序列,从而可以更加有效的支持UE-specific的唤醒或休眠方式。
在该举例中,S-WUS通过采用多级序列,可以获得更大的序列容量,避免了UE的S-WUS信号之间的干扰,从而可以更加有效的支持UE-specific的唤醒或休眠方式。
举例5(S-WUS节能方案1:配置周期性SL DRX):
本方案提供一种适用于直通链路的基于序列的第一节能信号S-WUS的发送方法:采用基于序列的直通链路第一节能信号S-WUS,指示第一终端在直通链路通信中被唤醒或休眠。而上述的被唤醒是指第一终端开始监听 PSCCH、开始进行资源感知以及开始进行资源选择等至少一项操作;被休眠是指第一终端停止监听PSCCH、停止进行资源感知以及停止进行资源选择等至少一项操作。
具体的,当直通链路上配置了周期性SL DRX时,第一节能信号S-WUS指示第一终端在S-WUS所关联的SL DRX周期内开始进行PSCCH监听、开始进行资源感知以及开始进行资源选择等至少一项操作;或者,第一节能信号S-WUS指示第一终端停止进行PSCCH监听、停止进行资源感知以及开始进行资源选择等至少一项操作;关于上述“开始”执行的操作具体可以是在周期开始时“开始”执行操作。
其中,处于周期性SL DRX的V2X(车辆网)UE,需要周期性的醒来监听PSCCH或进行资源感知或进行资源选择,这样,UE的大部分功耗消耗在周期性监听PSCCH并进行PSCCH的解调解码、或者周期性进行资源感知或资源选择上面,而不管UE是否真的有数据接收或发送的需求。同时,为了UE进行PSCCH解调,UE需要连续的执行信号处理,例如,信道跟踪,信道估计,以确保对于PSCCH解调解码的准确性。
但是,终端数据的到达一般是突发的,非周期的。所以,本举例中使用了第一节能信号S-WUS来指示后续的SL DRX周期内UE是否需要醒来(具体的为指示第一终端被唤醒或者被休眠)进行PSCCH的监测,或者是否需要醒来进行资源感知或资源选择。
第一节能信号S-WUS的上述指示是通过如下两种方法之一进行:方法1是第一节能信号S-WUS中包含有使得第一终端被唤醒或休眠的信息,例如通过不同的序列来指示被唤醒或休眠;方法2是通过第一节能信号S-WUS是否出现来指示第一终端被唤醒或休眠,即:第一节能信号S-WUS如果出现的话,就指示第一终端被唤醒,如果不出现的话,就指示第一终端被休眠。
本举例以节能信号是否出现作为第一节能信号S-WUS的指示方法为例,其中,第一节能信号S-WUS一般会被配置在一个DRX周期开始或结束的时域位置,在该时域位置,第一终端会检测第一节能信号S-WUS,如果第一节能信号S-WUS没有被检测到,则UE在整个SL DRX周期内不再醒来监测PSCCH,或不再醒来进行资源感知或资源选择;否则,如果第一节能信号 S-WUS被检测到了,UE需要醒来在后续的SL DRX周期内进行PSCCH的监测,或醒来进行资源感知或资源选择,从而可以在保证UE正常直通链路通信的同时,还能进一步降低UE的功耗。
如图5所示,第一终端配置了周期性SL DRX,并且具备图中所示的DRX周期。虚线方块代表第一节能信号S-WUS没有出现,实线方块代表第一节能信号S-WUS出现了。点状填充方框代表第一终端处于休眠状态,斜线填充方块代表第一终端处于被唤醒状态,并在被唤醒状态进行PSCCH监听、资源感知或资源选择操作。第一终端只有在第一节能信号S-WUS出现时,也就是第一终端检测到实线方块时,才会被唤醒过来;而如果第一节能信号S-WUS不出现,也就是第一终端在虚线方块位置检测不到第一节能信号S-WUS时,第一终端不会被唤醒过来,而是继续保持休眠状态。
在该举例中,给出了在配置了周期性SL DRX情况下的第一节能信号S-WUS节能方案,采用该方案,可以使用第一节能信号S-WUS来指示第一终端是否被唤醒或休眠,从而可以达到降低第一终端能耗的效果。
举例6(S-WUS节能方案2:未配置SL DRX或配置非周期性SL DRX):
本方案提供一种适用于直通链路的基于序列的第一节能信号S-WUS的发送方法:采用基于序列的直通链路第一节能信号S-WUS,指示第一终端在直通链路通信中被唤醒或休眠。而上述的被唤醒是指第一终端开始监听PSCCH、开始进行资源感知以及开始进行资源选择等至少一项操作;被休眠是指第一终端停止监听PSCCH、停止进行资源感知以及停止进行资源选择等至少一项操作。
其中,当未配置SL DRX或仅配置非周期性SL DRX时,第一节能信号S-WUS指示第一终端开始进行PSCCH监听、开始进行资源感知以及开始进行资源选择等至少一项操作;或者,第一节能信号S-WUS指示第一终端停止进行PSCCH监听、停止进行资源感知以及开始进行资源选择等至少一项操作。
当有数据到达时,第一节能信号S-WUS用来触发UE唤醒,进行PSCCH的监测,或者进行资源感知或资源选择,此时,UE可以从休眠状态转换为数据接收状态,从而可以开始各项操作。如果没有第一节能信号S-WUS被检测到,则UE可以继续休眠。此时,由于完全可以用第一节能信号S-WUS进行 数据收发的监听的触发,从而可以不用配置周期的DRX,或者是配置为完全匹配业务特性的非周期的DRX。
第一节能信号S-WUS的上述指示是通过如下两种方法之一进行:方法1是第一节能信号S-WUS中包含有使得第一终端被唤醒或休眠的信息,例如通过不同的序列来表示被唤醒或休眠;方法2是通过第一节能信号S-WUS是否出现来表示第一终端被唤醒或休眠,即:第一节能信号S-WUS如果出现的话,就指示第一终端被唤醒,如果不出现的话,就指示第一终端被休眠。
本举例以节能信号是否出现作为第一节能信号S-WUS的指示方法为例,其中,第一节能信号S-WUS会被配置非周期性出现,在第一节能信号S-WUS出现的时域位置,第一终端会检测第一节能信号S-WUS,如果第一节能信号S-WUS没有被检测到,则UE将不会醒来监测PSCCH,或不会醒来进行资源感知或资源选择。否则,如果第一节能信号S-WUS被检测到了,UE需要醒来进行PSCCH的监测,或醒来进行资源感知或资源选择,从而可以在保证UE正常直通链路通信的同时,还能进一步降低UE的功耗。
如图6所示,第一终端没有配置SL DRX。虚线方块代表第一节能信号S-WUS没有出现,实线方块代表S-WUS出现了。点状填充方框代表第一终端处于休眠状态,斜线填充方块代表第一终端处于被唤醒状态,并在被唤醒状态进行PSCCH监听、资源感知或资源选择操作。第一终端只有在S-WUS出现时,也就是第一终端检测到实线方块第一节能信号S-WUS时,才会被唤醒过来;而如果第一节能信号S-WUS不出现,也就是第一终端在虚线方块位置检测不到第一节能信号S-WUS时,第一终端不会被唤醒过来,而是继续保持休眠状态。
在该举例中,给出了在未配置SL DRX或仅配置非周期性SL DRX情况下的第一节能信号S-WUS节能方案,采用该方案,可以使用第一节能信号S-WUS来指示第一终端是否被唤醒或休眠,从而可以达到降低第一终端能耗的效果。
举例7(第一节能信号S-WUS的波束发送方式):
本方案中:
在FR1,第一节能信号S-WUS采用符号重复的方式进行发送,即:使用 至少两个OFDM符号发送相同的S-WUS序列。
在FR2,第一节能信号S-WUS采用波束扫描的方式进行发送,即:使用至少两个OFDM符号发送具有不同波束方向的S-WUS序列。
在不同的工作频段采取不同的波束发送方式,可以适应不同频段下的S-WUS信号的发送特点。在FR1,S-WUS往往采用宽波束进行发送,采用在多个OFDM符号中进行相同的S-WUS序列重复发送,可以让第一终端获得较高的S-WUS信号序列检测概率。而在FR2,S-WUS往往采用窄波束进行发送,采用波束扫描的方式在不同的OFDM符号中发送不同的S-WUS波束,也可以让第一终端获得较高的S-WUS信号序列检测概率。
使用上述方案,可以根据第一终端在进行直通链路通信时的工作频段的不同,灵活的选用不同的S-WUS的波束发送方式,从而可以让第一终端获得较高的S-WUS信号序列检测概率。
由上可知,本公开实施例提出了一种适用于直通链路的基于序列的节能信号(S-WUS,直通链路唤醒信号)的发送方法,采用基于序列的直通链路节能信号,指示第一终端在直通链路通信中被唤醒或休眠。使用该方法,避免了第一终端周期性监听PSCCH(物理直通链路控制信道)或持续资源感知而带来的电量消耗,从而可以使得第一终端根据业务需求进行PSCCH监听或资源感知或资源选择,降低了第一终端的耗电量。
