本申请实施例中的终端设备可以指用户设备(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、终端、无线通信设备、用户代理或用户装置。接入终端可以是蜂窝电话、无绳电话、会话启动协议(Session Initiation Protocol,SIP)电话、无线本地环路(Wireless Local Loop,WLL)站、个人数字处理(Personal Digital Assistant,PDA)、具有无线通信功能的手持设备、计算设备或连接到无线调制解调器的其它处理设备、车载设备、可穿戴设备,未来5G网络中的终端设备或者未来演进的公用陆地移动通信网络(Public Land Mobile Network,PLMN)中的终端设备等,本申请实施例并不限定。
本申请实施例中的网络设备可以是用于与终端设备通信的设备,该网络设备可以是GSM或CDMA中的基站(Base Transceiver Station,BTS),也可以是WCDMA***中的基站(NodeB,NB),还可以是LTE***中的演进型基站(Evolutional NodeB,eNB或eNodeB),还可以是云无线接入网络(Cloud Radio Access Network,CRAN)场景下的无线控制器,或者该网络设备可以为中继站、接入点、车载设备、可穿戴设备以及未来5G网络中的网络设备或者未来演进的PLMN网络中的网络设备等,本申请实施例并不限定。
本申请实施例中所涉及到的通信设备,可以是终端设备,也可以是网络设备。也就是说,可以是指终端设备和终端设备之间进行侧行通信,也可以是指终端设备和网络设备之间进行上下行通信。
图1和图2是本申请实施例的一个应用场景的示意图。图1示例性地示出了一个网络设备和两个终端设备,可选地,该无线通信***可以包括多个网络设备并且每个网络设备的覆盖范围内可以包括其它数量的终端设备,本申请实施例对此不做限定。此外,该无线通信***还可以包括移动管理实体(Mobile Management Entity,MME)、服务网关(Serving Gateway,S-GW)、分组数据网络网关(Packet Data Network Gateway,P-GW)等其他网络实体,但本申请实施例不限于此。
具体地,终端设备20和终端设备30可以以D2D通信模式进行通信,在进行D2D通信时,终端设备20和终端设备30通过D2D链路即侧行链路(Sidelink,SL)直接进行通信。例如图1或者图2所示,终端设备20和终端设备30通过侧行链路直接进行通信。在图1中,终端设备20和终端设备30之间通过侧行链路通信,其传输资源是由网络设备分配的;在图2中,终端设备20和终端设备30之间通过侧行链路通信,其传输资源是由终端设备自主选取的,不需要网络设备分配传输资源。
D2D通信模式可以应用于车对车(Vehicle to Vehicle,V2V)通信或车辆到其他设备(Vehicle to Everything,V2X)通信。在V2X通信中,X可以泛指任何具有无线接收和发送能力的设备,例如但不限于慢速移动的无线装置,快速移动的车载设备,或是具有无线发射接收能力的网络控制节点等。应理解,本申请实施例主要应用于V2X通信的场景,但也可以应用于任意其它D2D通信场景,本申请实施例对此不做任何限定。
在3GPP协议的版本Release-14中,定义了两种传输模式,即传输模式3(mode 3) 和传输模式4(mode 4)。使用传输模式3的终端设备的传输资源是由基站分配的,终端设备根据基站分配的资源在侧行链路上进行数据的发送;基站可以为终端设备分配单次传输的资源,也可以为终端设备分配半静态传输的资源。使用传输模式4的终端设备如果具备侦听能力,采用侦听(sensing)和预留(reservation)的方式传输数据,如果终端设备不具备侦听能力,则在资源池中随机选取传输资源。具备侦听能力的终端设备在资源池中通过侦听的方式获取可用的资源集合,终端设备从该集合中随机选取一个资源进行数据传输。由于车联网***中的业务具有周期性特征,因此终端设备通常采用半静态传输的方式,即终端设备选取一个传输资源后,就会在多个传输周期中持续的使用该资源,从而降低资源重选以及资源冲突的概率。终端设备会在本次传输的控制信息中携带预留下次传输资源的信息,从而使得其他终端设备可以通过检测该终端设备的控制信息判断这块资源是否被该终端设备预留和使用,达到降低资源冲突的目的。
在LTE***中,频域资源都是在整个***带宽中分配的。在NR***中,由于***带宽大大提高,终端传输带宽可能只占有***带宽一部分。那么对于NR-V2X来说,终端设备不可能在整个***带宽上选择资源池进行侧行通信,因此,就需要将***带宽进行细分,并在细分后的带宽范围内选择资源池,在有多个资源池存在的情况下,终端设备如何进行资源池之间的切换是需要解决的问题。
图3示出了本申请实施例的切换资源池的方法100的示意性框图。该方法100可以由图1或图2中的某个终端设备执行,该方法100包括以下部分或全部内容:
S110,第一终端设备获取第一指示信息;
S120,所述第一终端设备根据所述第一指示信息,将侧行链路的资源池从第一资源池切换到第二资源池。
具体地,该第一终端设备可以是图1或图2中的终端设备20或终端设备30。该第一终端设备可以首先获取第一指示信息,例如该第一终端设备从网络设备处获取该第一指示信息,或者也可以从其他终端设备处获取该第一指示信息,进而该第一终端设备可以根据该第一指示信息,进行侧行链路的资源池切换。例如,从第一资源池切换到第二资源池,该第一资源池可以是当前使用的资源池。
因此,本申请实施例的切换资源池的方法,根据第一指示信息的指示来进行侧行链路上资源池的切换,从而使得第一终端设备能够及时进行资源池的切换,以保证在合适的时频资源上进行侧行通信,以提高侧行通信的性能。
可选地,该第一指示信息可以是直接指示第一终端设备进行资源池的切换,即该第一指示信息用于指示将侧行链路的资源池从第一资源池切换到第二资源池,或者,该第一指示信息用于指示将侧行链路的资源池切换到第二资源池,或者,该第一指示信息用于指示激活第二资源池。例如,该第一指示信息携带第二资源池的信息以及切换命令/激活命令,第一终端设备在接收到该第一指示信息之后,就可以直接将当前处于工作状态的第一资源池切换到第二资源池,也就是说,第一终端设备在接收到该第一指示信息之后即可在该第二资源池上进行侧行通信。其中,该切换命令/激活命令可以是一个指示域,例如可以是一个特定比特位,若该比特位为1,则表示该第一指示信息是一个切换信息/激活命令。在该第一指示信息中可以包括一个信息域,用于指示第二资源池的信息,第一终端设备可以在该第一指示信息中获取第二资源池的信息,并以此将侧行链路的资源池切换到第二资源池。
可选地,该第一指示信息也可以是间接指示第一终端设备进行资源池的切换。
在NR目前的研究中,已经引入带宽部分(bandwidth part,BWP)概念,实现比***带宽更小范围的频域资源分配。网络设备可以通过无线资源控制(Radio Resource Control,RRC)信令配置多个BWP,然后在下行控制信令(Downlink Control Information,DCI)中动态的激活某个BWP。每种BWP可以基于一种基础参数集(包括子载波间隔、循环前缀(Cyclic Prefix,CP))。按目前的方案,针对一个终端设备只能激活一个BWP,当激活一个新的BWP的同时,原有的BWP就被去激活。当激活某个BWP时,同时会重置该BWP的定时器,如果定时器超时,则会回落到缺省BWP。
如图4所示,在BWP1处于激活状态时,如果激活BWP2,BWP1就会被去激活。当激活一个BWP时,会同时重置该BWP的定时器,例如,当激活BWP1时,同时会重置该BWP1的定时器,如果在该定时器超时的情况下,则会激活缺省BWP,BWP1去激活。
在V2X***中,没有BWP的概念,当侧行链路和上行链路共用一个载波,即V2X工作在上行载波上时,并且终端只有一个发射链,当网络配置终端从一个上行BWP切换到另外一个上行BWP时,如果终端的侧行链路仍然工作在原来的传输资源上,就会导致终端的上行资源在一个频域范围内,侧行链路传输资源在另外一个频域范围内,从而导致终端在一个时刻只能发送上行或者侧行链路的数据。
同样地,当侧行链路和下行链路共用一个载波,即V2X工作在下行载波上时,并且终端只有一个接收链,当网络配置终端从一个下行BWP切换到另一个下行BWP时,如果终端的侧行链路仍然工作在原来的传输资源上,就会导致终端的下行资源在一个频域范围内,侧行链路传输资源在另外一个频域范围内,从而导致终端在一个时刻只能接收下行或者侧行链路的数据。
因此,在为终端配置资源池时,可以将资源池与BWP关联,即该资源池的频域资源在关联的BWP的带宽范围内,在配置终端进行BWP切换时,终端也可以进行资源池的切换。
也就是说,在本申请实施例中,该第一指示信息可以用于指示将BWP从第一BWP切换到第二BWP,或者,该第一指示信息可以用于指示将BWP切换到第二BWP,或者,该第一指示信息可以用于指示激活第二BWP。其中,该第一BWP可以是当前处于激活态的BWP。例如,该第一指示信息可以携带第二BWP的信息,该第一指示信息还可以携带一个指示域,当第一终端设备接收到该第一指示信息之后,可以激活第二BWP,同时去激活第一BWP。该第一终端设备在接收到该第一指示信息之后,还可以激活与第二BWP关联的资源池,例如第二资源池,同时去激活与第一BWP关联的资源池,例如第一资源池。即当第一终端设备将BWP从第一BWP切换到第二BWP时,将侧行链路的资源池也从第一BWP上的资源池切换到第二BWP上的资源池。
可选地,网络设备在为第一终端设备配置资源池时,该资源池的配置信息可以包括该资源池的信息,以及对应的BWP的信息。该BWP的信息可以包括以下信息中的至少一种:BWP的索引、BWP所占的带宽范围、该BWP所支持的基础参数集,以及相关的测量参数(无线资源管理(Radio Resource Management,RRM)测量和无线链路监测(Radio Link Monitoring,RLM)测量)等。
其中,网络设备为第一终端设备配置的任何一个BWP均可支持至少一种基础参数 集。而某个BWP上的资源池所支持的基础参数集为该BWP所支持的基础参数集中的任意组合。例如,第一BWP上支持两种基础参数集,该第一BWP上的资源池可以支持该两种基础参数集中的任一种,也可以支持该两种基础参数集。
若网络设备为第一终端设备配置多个BWP,该多个BWP分别支持的基础参数集可以完全不同,也可以部分相同,还可以完全相同。例如,网络设备为第一终端设备配置BWP1和BWP2,该BWP1支持两种基础参数集,该BWP2支持三种基础参数集,该BWP2支持的三种基础参数集可以包括该BWP1支持的两种基础参数集。再例如,网络设备为第一终端设备配置BWP1和BWP2,该BWP1支持一种基础参数集,该BWP2支持与BWP1不同的另外一种基础参数集。
由于可能存在不同BWP支持相同的基础参数集,那么当第一终端设备进行BWP的切换时,所使用的基础参数集也可以不进行切换。
可选地,在为终端配置资源池时,也可以将资源池与基础参数集关联,即一个资源池配置至少一种基础参数集,在配置终端进行基础参数集的切换时,终端也可以进行资源池的切换。
也就是说,在本申请实施例中,该第一指示信息可以用于指示将基础参数集从第一种基础参数集切换到第二种基础参数集,或者,该第一指示信息可以用于指示将基础参数集切换到第二种基础参数集,或者,该第一指示信息可以用于指示激活第二种基础参数集。其中,该第一种基础参数集可以是当前处于激活态的基础参数集。例如,该第一指示信息可以携带第二种基础参数集的信息,该第一指示信息还可以携带一个指示域,当第一终端设备接收到该第一指示信息之后,可以激活第二种基础参数集,同时去激活第一种基础参数集。该第一终端设备在接收到该第一指示信息之后,还可以激活与第二种基础参数集关联的资源池,例如第二资源池,同时去激活与第一种基础参数集关联的资源池,例如第一资源池。即当第一终端设备将基础参数集从第一种基础参数集切换到第二种基础参数集时,将侧行链路的资源池也从第一种基础参数集对应的资源池切换到第二基础参数集对应的资源池。
可选地,网络设备在为第一终端设备配置资源池时,该资源池的配置信息可以包括该资源池的信息以及该资源池的基础参数集信息。
其中,网络设备在为第一终端设备配置某个资源池时,可以将该资源池与基础参数集关联起来,例如,可以配置第一资源池支持至少一种基础参数集,配置第二资源池也支持至少一种基础参数集。该资源池的频域资源也可以在关联的BWP的带宽范围内。换句话说,该资源池的配置信息还可以包括对应的BWP的信息。
若网络设备为第一终端设备配置多个资源池,该多个资源池的频域资源均可以在同一个BWP的带宽范围内,也可以是部分资源池的频域资源在一个BWP的带宽范围内,其他部分资源池的频域资源分别在之外的不同BWP的带宽范围内。换句话说,对于本申请实施例中的第一资源池和第二资源池,该第一资源池和第二资源池可以都在第一BWP内,并且该第一BWP既支持第一资源池支持的基础参数集,如第一种基础参数集,又支持第二资源池支持的基础参数集,如第二种基础参数集。可选地,该第一资源池和第二资源池也可以在不同的BWP内,如第一资源池在第一BWP内,第二资源池在第二BWP内,该第一BWP支持第一资源池支持的基础参数集,如第一种基础参数集,该第二BWP支持第二资源池支持的基础参数集,如第二种基础参数集。其中,该第一BWP可以支持 至少一种基础参数集,该第二BWP可以支持至少一种基础参数集。
可选地,本申请实施例所涉及的资源池包括发送资源池和/或接收资源池。
下面将通过几个具体的实施例来详细描述本申请技术方案。
实施例1:当侧行链路和上行链路共享载波时,侧行链路工作在上行链路载波上,上行配置了两个BWP:BWP1和BWP2,在BWP1上配置了发送资源池TX_RP1和TX_RP2,配置了接收资源池RX_RP1;在BWP2上配置了发送资源池TX_RP3和TX_RP4,配置了接收资源池RX_RP2和RX_RP3;当网络配置用户工作在上行BWP1时,侧行链路的发送资源池使用BWP1上的TX_RP1和/或TX_RP2,接收资源池使用BWP1上的RX_RP1;当网络配置用户从上行BWP1切换到BWP2时,该用户侧行链路的资源池也切换到BWP2上的发送资源池TX_RP3和TX_RP4,以及接收资源池RX_RP2和RX_RP3。
实施例2:当侧行链路和上行链路共享载波时,侧行链路工作在上行链路载波上,上行配置了两个BWP:BWP1和BWP2。在BWP1上支持15KHz和30kHz两种子载波间隔,配置了发送资源池TX_RP1对应15kHz的子载波间隔,TX_RP2对应30kHz的子载波间隔,配置了接收资源池RX_RP1对应15kHz的子载波间隔,RX_RP2对应30kHz的子载波间隔;在BWP2上支持30KHz和60kHz两种子载波间隔,配置了发送资源池TX_RP3对应30kHz的子载波间隔,TX_RP4对应60kHz的子载波间隔,配置了接收资源池RX_RP3对应30kHz的子载波间隔,RX_RP4对应60kHz的子载波间隔。当网络配置终端工作在BWP1上,并且工作在15kHz的子载波间隔时,终端使用TX_RP1和RX_RP1,当网络配置终端工作在BWP1上,并且工作在30kHz的子载波间隔时,终端使用TX_RP2和RX_RP2,当网络配置终端工作在BWP2上,并且工作在30kHz的子载波间隔时,终端使用TX_RP3和RX_RP3,当网络配置终端工作在BWP2上,并且工作在60kHz的子载波间隔时,终端使用TX_RP4和RX_RP4。
实施例3:在实施例2的场景下,如果当前工作在BWP1上,网络配置从15kHz切换到30kHz时,终端不需要进行BWP切换,只需要将发送资源池从TX_RP1切换到TX_RP2,接收资源池从RX_RP1切换到RX_RP2;如果当前工作在BWP1上,并且是15kHz子载波间隔,网络配置BWP1的第一类子载波间隔(即15kHz)切换到BWP2的第二类子载波间隔(即60kHz)时,终端需要进行BWP切换,并且将发送资源池从TX_RP1切换到TX_RP4,接收资源池从RX_RP1切换到RX_RP4。
可选地,也可以是侧行链路和下行链路共享载波,使用上述相同的方式配置以及切换资源池,为了简洁,此处不再赘述。
需要说明的是,关于资源池的配置可以是由网络设备向第一终端设备配置,也可以是由协议约定的,还可以是由其他终端设备配置的。也就是说,第一终端设备在获取第一指示信息之前首先得获取第一配置信息,该第一配置信息用于指示资源池的参数,例如,该资源池的时频资源信息,对应的BWP的信息,基础参数集信息等。该第一配置信息可以是网络发送的配置信息,也可以是预存在第一终端设备内部的预配置信息,还可以是由其他终端设备发送的,例如,组播通信中的组头为组成员配置资源池信息。
在一种可能的实现方式中,该第一指示信息可以承载在第一侧行信道中。也就是说,该第一指示信息可以是其他终端设备发送给第一终端设备的。该第一指示信息可以承载在包括但不限于物理侧行控制信道(Physical Sidelink Control Channel,PSCCH),或物理侧行共享信道(Physical Sidelink Shared Channel,PSSCH),或物理侧行广播信道(Physical  Sidelink Broadcast Channel,PSBCH)等各种侧行信道中。
在另一种可能的实现方式中,该第一指示信息也可以承载在下行信道中。也就是说,该第一指示信息可以是由网络设备发送给第一终端设备的。该第一指示信息可以承载在包括但不限于广播信息、无线资源控制(Radio Resource Control,RRC)信令或下行控制信息(Downlink Control Information,DCI)等下行信息中。
应理解,本申请实施例中的“第一”并不意味着一定会有“第二”,只是一种术语表达而已。例如,本申请实施例中的“第一指示信息”,并不代表一定会有“第二指示信息”。
还应理解,本文中术语“***”和“网络”在本文中常被可互换使用。本文中术语“和/或”,仅仅是一种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,本文中字符“/”,一般表示前后关联对象是一种“或”的关系。
