具体实施方式
为了使本申请的目的、技术方案和优点更加清楚,下面将结合附图对本申请作进一步地详细描述,显然,所描述的实施例仅仅是本申请一部份实施例,而不是全部的实施例。基于本申请中的实施例,本领域普通技术人员在 没有做出创造性劳动前提下所获得的所有其它实施例,都属于本申请保护的范围。
以下对本申请实施例中的部分用语进行解释说明,以便于本领域技术人员理解。
(1)本申请实施例中,名词“网络”和“系统”经常交替使用,但本领域的技术人员可以理解其含义。
(2)本申请实施例中术语“多个”是指两个或两个以上,其它量词与之类似。
(3)“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这三种情况。字符“/”一般表示前后关联对象是一种“或”的关系。
对于设备和设备之间的通信链路为直接通信链路(Sidelink),直接通信设备对应的无线接口为Sidelink接口;网络侧设备与直接通信设备之间的蜂窝通信链路为终端和网络设备之间的链路(Uu link),网络侧设备与直接通信设备对应的无线接口为终端和网络设备之间的接口(Uu)。
在第三代合作伙伴项目新空口车到万物技术(the 3rd Generation Partnership Project New Radio vehicle to X,3GPP NR V2X)立项文件中讨论到Uu接口辅助直接通信接口资源分配时提出了三种场景,如表1所示:
Figure PCTCN2019092108-appb-000001
表1
从表1中可以看出,Uu link使用的无线接入技术和Sidelink使用的无线 接入技术可以任意组合,比如,Uu link使用的无线接入技术为LTE,Sidelink使用的无线接入技术为NR。
对于Uu link,终端一旦确定了驻留小区,该Uu link使用的无线接入技术就确定了,此时,如果终端直接通信接口有数据传输需求,并且终端在直接通信接口同时支持无线接入技术NR和无线接入技术LTE,则需要明确终端在直接通信接口上应该选择何种无线接入技术进行数据传输。
本申请实施例描述的应用场景是为了更加清楚的说明本申请实施例的技术方案,并不构成对于本申请实施例提供的技术方案的限定,本领域普通技术人员可知,随着新应用场景的出现,本申请实施例提供的技术方案对于类似的技术问题,同样适用。
针对上述场景,本申请提供了一种确定直接通信接口使用的无线接入技术的系统结构示意图,具体如图1所示,该系统中包括:
终端10,用于确定自身在直接通信接口支持的无线接入技术;若在直接通信接口支持多种无线接入技术,则从所述多种无线接入技术中选择自身在直接通信接口使用的无线接入技术。
网络侧设备20,用于确定终端需要使用直接通信接口;确定终端在直接通信接口使用的无线接入技术。
本申请实施例中,终端确定自身在直接通信接口支持的无线接入技术,如果终端在直接通信接口支持多种无线接入技术,则该终端从多种无线接入技术中选择自身在直接通信接口使用的无线接入技术,相应的,当终端有直接通信需求时,网络侧设备确定终端需要使用直接通信接口,然后确定终端在直接通信接口使用的无线接入技术,由于终端从该终端支持的多种无线接入技术中选择在直接通信接口使用的无线接入技术以及网络侧设备确定终端在直接通信接口使用的无线接入技术,并且需要保证终端和网络侧设备对终端在直接通信接口使用的无线接入技术理解的一致性,从而使终端根据终端选择的无线接入技术或网络侧设备确定的无线进入技术在直接通信接口进行数据传输,进而保证网络侧设备根据终端在直接通信接口使用的无线接入技 术进行合理的资源分配。
本申请实施例中,所述终端是一种具有直接通信功能的设备,可以部署在陆地上,包括室内或室外、手持或车载;也可以部署在水面上(如轮船等);还可以部署在空中(例如飞机、气球和卫星上等)。所述终端可以是手机(mobile phone)、平板电脑(pad)、带无线收发功能的电脑、虚拟现实(virtual reality,VR)所述终端、增强现实(augmented reality,AR)所述终端、工业控制(industrial control)中的无线所述终端、无人驾驶(self driving)中的无线所述终端、远程医疗(remote medical)中的无线所述终端、智能电网(smart grid)中的无线所述终端、运输安全(transportation safety)中的无线所述终端、智慧城市(smart city)中的无线所述终端、智慧家庭(smart home)中的无线所述终端等;还可以是各种形式的用户设备(User Equipment,UE),移动台(mobile station,MS),所述终端设备(terminal device)。
所述网络侧设备是一种为所述终端提供无线通信功能的设备,包括但不限于:5G中的gNB、无线网络控制器(radio network controller,RNC)、节点B(node B,NB)、基站控制器(base station controller,BSC)、基站收发台(base transceiver station,BTS)、家庭基站(例如,home evolved nodeB,或home node B,HNB)、基带单元(BaseBand Unit,BBU)、传输点(transmitting and receiving point,TRP)、发射点(transmitting point,TP)、移动交换中心等。
对于直接通信的设备,可以是在网的,也可以是脱网的,还可以是部分设备在网,部分设备脱网。所谓在网,即参与直接通信的设备位于3GPP直接通信载波覆盖范围内;所谓脱网,即参与直接通信的设备不在3GPP直接通信载波覆盖范围内。
典型的直接通信场景包括如下三种:
直接通信,即设备一对一进行通信;
组通信,即一个设备一次可以给一个通信群组里的所有设备发送相同数据;
广播通信,即一个设备一次可以给所有附近的设备发送相同数据。
本申请实施例中的直接通信的设备为在网的直接通信设备;直接通信场景为以上三种直接通信场景中的任何一种。
在实施中,终端确定自身在直接通信接口支持的无线接入技术,可以根据终端能力信息确定。
这里的终端能力信息,是该终端能够支持何种无线接入技术,比如仅支持LTE无线接入技术;仅支持NR无线接入技术;既支持LTE无线接入技术,又支持NR无线接入技术。
本申请实施例中的无线接入技术为基于LTE Rel-14的直接通信接口无线接入技术、基于LTE Rel-15的直接通信接口无线接入技术、基于NR的直接通信接口无线接入技术。
终端支持以上三种无线接入技术中的部分或全部。
终端确定自身在直接通信接口支持的无线接入技术,如果终端在直接通信接口支持多种无线接入技术,比如终端在直接通信接口既支持基于LTE Rel-14无线接入技术,又支持基于NR无线接入技术,则终端需要从多种无线接入技术中选择在终端的直接通信接口使用的无线接入技术,本申请实施例给出了8种终端从多种无线接入技术中选择自身在直接通信接口使用的无线接入技术的方式,下面分别进行说明。
方式一、终端将预设的无线接入技术作为自身在直接通信接口使用的无线接入技术。
这里预设的无线接入技术,为终端在直接通信接口支持的无线接入技术中的一个,比如终端在直接通信接口支持的无线接入技术有三种,分别为基于LTE Rel-14的直接通信接口无线接入技术、基于LTE Rel-15的直接通信接口无线接入技术、基于NR的直接通信接口无线接入技术,则预设的无线接入技术为基于LTE Rel-14的直接通信接口无线接入技术、基于LTE Rel-15的直接通信接口无线接入技术、基于NR的直接通信接口无线接入技术中的一种。
需要说明的是,预设的无线接入技术,可以是终端和网络侧设备预先商量好的,比如对于终端1,终端1直接通信接口支持两种无线接入技术,基于 LTE Rel-14的直接通信接口无线接入技术和基于NR的直接通信接口无线接入技术,在终端有直接通信需求之前,终端和网络侧设备预先商量好使用基于NR的直接通信接口无线接入技术,则在终端1有直接通信需求时,在直接通信接口使用基于NR的直接通信接口无线接入技术进行数据传输。
为了便于理解终端将预设的无线接入技术作为自身在直接通信接口使用的无线接入技术,下面以具体实施例进行说明。
实施例一:
对于在网的终端,比如无线资源控制空闲(Radio Resource Control_IDLE,RRC_IDLE)态终端、无线资源控制非激活(RRC_INACTIVE)态终端、无线资源控制连接(RRC_CONNECTED)态终端,如果在该终端直接通信接口有数据传输需求,则终端根据该终端能力信息确定终端在直接通信接口支持的无线接入技术。
如果终端在直接通信接口仅支持一种无线接入技术,则终端在直接通信接口使用该无线接入技术进行数据的传输;如果终端在直接通信接口支持多种无线接入技术,比如既支持基于LTE Rel-14的直接通信接口无线接入技术,又支持基于NR的直接通信接口无线接入技术,则终端将预设的无线接入技术作为终端在直接通信接口使用的无线接入技术,比如预设的无线接入技术为基于NR的直接通信接口无线接入技术,则终端将基于NR的直接通信接口无线接入技术作为终端在直接通信接口使用的无线接入技术。
需要说明的是,预设的无线接入技术可以是终端和网络侧设备之间使用的无线接入技术,即Uu link使用的无线接入技术;也可以是固定使用的一种无线接入技术,比如终端在直接通信接口同时支持基于LTE Rel-14的直接通信接口无线接入技术和基于NR的直接通信接口无线接入技术,则预设的无线接入技术可以是固定使用基于LTE Rel-14的直接通信接口无线接入技术或固定使用基于NR的直接通信接口无线接入技术;还可以是协议约定的直接通信接口的无线接入技术或者预配置在终端中的直接通信接口的无线接入技术。
当终端将预设的无线接入技术作为自身在直接通信接口使用的无线接入 技术时,相应地,网络侧设备将该终端预设的无线接入技术作为该终端自身在直接通信接口使用的无线接入技术,也就是网络侧设备确定终端在直接通信接口使用的无线接入技术为预设的无线接入技术。
网络侧设备确定了终端在直接通信接口使用的无线接入技术后,根据终端在直接通信接口使用的无线接入技术进行合理的资源分配。
方式二、终端将在终端与网络侧设备之间的接口使用的无线接入技术作为自身在直接通信接口使用的无线接入技术。
由于是在网终端,所以终端与网络侧设备连接,当终端与网络侧设备连接后,终端与网络侧设备之间的接口使用的无线接入技术已经确定,所以在终端从该终端支持的多种无线接入技术中选择自身在直接通信接口使用的无线接入技术时,可以将在终端与网络侧设备之间的接口使用的无线接入技术作为该终端在直接通信接口使用的无线接入技术。
为了便于理解终端将在终端与网络侧设备之间的接口使用的无线接入技术作为自身在直接通信接口使用的无线接入技术,下面以具体实施例进行说明。
实施例二:
对于在网的终端,比如RRC_IDLE终端、RRC_INACTIVE终端、RRC_CONNECTED终端,如果在该终端直接通信接口有数据传输需求,则终端根据该终端能力信息确定终端在直接通信接口支持的无线接入技术。
如果终端在直接通信接口仅支持一种无线接入技术,则终端在直接通信接口使用该无线接入技术进行数据的传输;如果终端在直接通信接口支持多种无线接入技术,比如既支持基于LTE Rel-14的直接通信接口无线接入技术,又支持基于NR的直接通信接口无线接入技术,则终端将在终端与网络侧设备之间的接口使用的无线接入技术作为自身在直接通信接口使用的无线接入技术。
比如终端在直接通信接口支持两种无线接入技术,基于LTE Rel-14的直接通信接口无线接入技术和基于NR的直接通信接口无线接入技术,终端在选 择自身在直接通信接口使用的无线接入技术时,终端首先判断该终端与网络侧设备之间的接口使用的无线接入技术是基于LTE Rel-14的直接通信接口无线接入技术还是基于NR的直接通信接口无线接入技术,如果终端与网络侧设备之间的接口使用的无线接入技术为基于LTE Rel-14的直接通信接口无线接入技术,则终端将基于LTE Rel-14的直接通信接口无线接入技术作为终端在直接通信接口使用的无线接入技术;如果终端与网络侧设备之间的接口使用的无线接入技术为基于NR的直接通信接口无线接入技术,则终端将基于NR的直接通信接口无线接入技术作为终端在直接通信接口使用的无线接入技术。
相应地,当终端在直接通信接口有数据传输需求时,终端会将该需求上报给网络侧设备,网络侧设备接收到终端上报的需求后,确定终端需要使用直接通信接口,网络侧设备确定终端在直接通信接口使用的无线接入技术。
当终端将在终端与网络侧设备之间的接口的无线接入技术作为自身在直接通信接口使用的无线接入技术时,相应地,网络侧设备将该终端与网络侧设备之间的接口使用的无线接入技术作为该终端在直接通信接口使用的无线接入技术。
网络侧设备确定了终端在直接通信接口使用的无线接入技术后,根据终端在直接通信接口使用的无线接入技术进行合理的资源分配。
方式三、终端根据发送参数Tx Profile标识和直接通信接口使用的无线接入技术之间的映射关系将当前数据包的发送参数Tx Profile标识对应的直接通信接口使用的无线接入技术作为自身在直接通信接口使用的无线接入技术。
需要说明的是,终端发送数据包时,数据包对应一个发送参数Tx Profile,Tx Profile会有Tx Profile标识,终端根据Tx profile标识和直接通信接口使用的无线接入技术之间的映射关系确定自身在直接通信接口使用的无线接入技术,并将该无线接入技术作为终端在直接通信接口支持的无线接入技术。
为了便于理解终端根据发送参数Tx Profile标识和直接通信接口使用的无线接入技术之间的映射关系将当前数据包的发送参数Tx Profile标识对应的直接通信接口使用的无线接入技术作为自身在直接通信接口使用的无线接入技 术,下面以具体实施例进行说明。
实施例三:
对于在网的终端,比如RRC_IDLE终端、RRC_INACTIVE终端、RRC_CONNECTED终端,如果在该终端直接通信接口有数据传输需求,则终端根据该终端能力信息确定终端在直接通信接口支持的无线接入技术。
如果终端在直接通信接口仅支持一种无线接入技术,则终端在直接通信接口使用该无线接入技术进行数据的传输;如果终端在直接通信接口支持多种无线接入技术,比如既支持基于LTE Rel-14的直接通信接口无线接入技术,又支持基于NR的直接通信接口无线接入技术,则根据发送参数Tx Profile标识和直接通信接口使用的无线接入技术之间的映射关系将当前数据包的发送参数Tx Profile标识对应的直接通信接口使用的无线接入技术作为自身在直接通信接口使用的无线接入技术。
比如终端在直接通信接口支持两种无线接入技术,基于LTE Rel-14的直接通信接口无线接入技术和基于NR的直接通信接口无线接入技术,发送参数Tx Profile标识和直接通信接口使用的无线接入技术之间的映射关系中发送参数Tx Profile标识A对应的直接通信接口使用的无线接入技术为基于NR的直接通信接口无线接入技术,当终端在直接通信接口有数据传输时,数据包对应的发送参数Tx Profile标识为A,则终端将基于NR的直接通信接口无线接入技术作为终端在直接通信接口使用的无线接入技术。
终端根据发送参数Tx Profile标识和直接通信接口使用的无线接入技术之间的映射关系将当前数据包的发送参数Tx Profile标识对应的直接通信接口使用的无线接入技术作为自身在直接通信接口使用的无线接入技术后,终端将自身在直接通信接口使用的无线接入技术通知该网络侧设备。
比如,终端根据发送参数Tx Profile标识和直接通信接口使用的无线接入技术之间的映射关系确定当前数据包的发送参数Tx Profile标识对应的直接通信接口使用的无线接入技术为基于NR的直接通信接口无线接入技术,则终端将基于NR的直接通信接口无线接入技术作为终端在直接通信接口使用的无 线接入技术,并将基于NR的直接通信接口无线接入技术通知给网络侧设备,以使网络侧设备知道终端在直接通信接口使用的无线接入技术为基于NR的直接通信接口无线接入技术。
相应地,网络侧设备接收终端通知的该终端在直接通信接口使用的无线接入技术,然后根据终端在直接通信接口使用的无线接入技术进行合理的资源分配。
方式四、终端根据V2X业务标识和直接通信接口使用的无线接入技术的映射关系将当前V2X业务对应的直接通信接口使用的无线接入技术作为自身在直接通信接口使用的无线接入技术。
需要说明的是,V2X业务标识的内容为PSID或ITS-AIDs。
在实施中,终端中可以存储V2X业务标识和直接通信接口使用的无线接入技术的映射关系,终端首先确定当前V2X业务对应的V2X业务标识,然后根据V2X业务标识和直接通信接口使用的无线接入技术的映射关系,确定该V2X业务标识对应的直接通信接口使用的无线接入技术,最后将确定的直接通信接口使用的无线接入技术作为自身在直接通信接口使用的无线接入技术。
为了便于理解终端根据V2X业务标识和直接通信接口使用的无线接入技术的映射关系将当前V2X业务对应的直接通信接口使用的无线接入技术作为自身在直接通信接口使用的无线接入技术,下面以具体实施例进行说明。
实施例四:
对于在网的终端,比如RRC_IDLE终端、RRC_INACTIVE终端、RRC_CONNECTED终端,如果在该终端直接通信接口有数据传输需求,则终端根据该终端能力信息确定终端在直接通信接口支持的无线接入技术。
如果终端在直接通信接口仅支持一种无线接入技术,则终端在直接通信接口使用该无线接入技术进行数据的传输;如果终端在直接通信接口支持多种无线接入技术,比如既支持基于LTE Rel-14的直接通信接口无线接入技术,又支持基于NR的直接通信接口无线接入技术,则终端根据V2X业务标识和直接通信接口使用的无线接入技术的映射关系将当前V2X业务对应的直接通 信接口使用的无线接入技术作为自身在直接通信接口使用的无线接入技术。
比如,终端在直接通信接口支持两种无线接入技术,基于LTE Rel-14的直接通信接口无线接入技术和基于NR的直接通信接口无线接入技术,终端中存储的V2X业务标识和直接通信接口使用的无线接入技术的映射关系为V2X业务标识A对应的无线接入技术为基于LTE Rel-14的直接通信接口无线接入技术,V2X业务标识B对应的无线接入技术为基于NR的直接通信接口无线接入技术,假如终端当前V2X业务对应的V2X业务标识为V2X业务标识A,则终端将基于LTE Rel-14的直接通信接口无线接入技术作为直接通信接口使用的无线接入技术。
这里需要说明的是,一个直接通信接口使用的无线接入技术可以对应一个V2X业务标识,也可以对应多个V2X业务标识,比如V2X业务标识A对应的无线接入技术为基于LTE Rel-14的直接通信接口无线接入技术,V2X业务标识C对应的无线接入技术也为基于LTE Rel-14的直接通信接口无线接入技术。
终端根据V2X业务标识和直接通信接口使用的无线接入技术的映射关系将当前V2X业务对应的直接通信接口使用的无线接入技术作为自身在直接通信接口使用的无线接入技术后,终端将直接通信接口使用的无线接入技术通知该网络侧设备。
相应地,网络侧设备接收终端通知的该终端在直接通信接口使用的无线接入技术,然后根据终端在直接通信接口使用的无线接入技术进行合理的资源分配。
方式五、终端根据直接通信业务的QoS参数和直接通信接口使用的无线接入技术的映射关系将当前直接通信业务的QoS参数对应的直接通信接口使用的无线接入技术作为自身在直接通信接口使用的无线接入技术。
这里需要说明的是,目前直接通信接口的QoS参数主要有三个,每个直接通信数据包的优先级(ProSe Priority Per Packet,PPPP)、每个直接通信数据包的可靠性(ProSe Realibility Per Packet,PPPR)以及数据包时延预算(Packet  Delay Budge,PDB),随着标准的推进,后续还会引入其他直接通信接口的QoS参数。

比如,终端在直接通信接口支持的无线接入技术有两种,基于LTE Rel-14的直接通信接口无线接入技术和基于NR的直接通信接口无线接入技术。终端在直接通信接口存在3个直接通信业务传输需求,直接通信业务A、直接通信业务B和直接通信业务C。针对直接通信业务A,直接通信业务A的QoS参数为1,直接通信业务的QoS参数和直接通信接口使用的无线接入技术的映射关系中QoS参数为1时对应的直接通信接口使用的无线接入技术为基于LTE Rel-14的直接通信接口无线接入技术,则终端在直接通信接口对直接通信业务A传输时,将基于LTE Rel-14的直接通信接口无线接入技术作为终端在直接通信接口使用的无线接入技术;
针对直接通信业务B,直接通信业务B的QoS参数为0,直接通信业务的QoS参数和直接通信接口使用的无线接入技术的映射关系中QoS参数为0时对应的直接通信接口使用的无线接入技术为基于NR的直接通信接口无线接入技术,则终端在直接通信接口对直接通信业务B传输时,将基于NR的直接通信接口无线接入技术作为终端在直接通信接口使用的无线接入技术;
针对直接通信业务C,直接通信业务C的QoS参数为1,则终端在直接通信接口对直接通信业务C传输时,将基于LTE Rel-14的直接通信接口无线接入技术作为终端在直接通信接口使用的无线接入技术。
终端根据直接通信业务的QoS参数和直接通信接口使用的无线接入技术的映射关系将当前直接通信业务的QoS参数对应的直接通信接口使用的无线接入技术作为自身在直接通信接口使用的无线接入技术的三种情形介绍完后,为了便于理解下面以具体实施例进行说明。
实施例五:
对于在网的终端,比如RRC_IDLE终端、RRC_INACTIVE终端、RRC_CONNECTED终端,如果在该终端直接通信接口有数据传输需求,则终端根据该终端能力信息确定终端在直接通信接口支持的无线接入技术。
如果终端在直接通信接口仅支持一种无线接入技术,则终端在直接通信接口使用该无线接入技术进行数据的传输;如果终端在直接通信接口支持多种无线接入技术,比如既支持基于LTE Rel-14的直接通信接口无线接入技术,又支持基于NR的直接通信接口无线接入技术,则终端根据直接通信业务的QoS参数和直接通信接口使用的无线接入技术的映射关系将当前直接通信业务的QoS参数对应的直接通信接口使用的无线接入技术作为自身在直接通信接口使用的无线接入技术。
终端根据直接通信业务的QoS参数和直接通信接口使用的无线接入技术的映射关系将当前直接通信业务的QoS参数对应的直接通信接口使用的无线接入技术作为自身在直接通信接口使用的无线接入技术后,终端将直接通信接口使用的无线接入技术通知该网络侧设备。
相应地,网络侧设备接收终端通知的该终端在直接通信接口使用的无线接入技术,然后根据终端在直接通信接口使用的无线接入技术进行合理的资源分配。
方式六、终端根据实现算法从多种无线接入技术中选择自身在直接通信接口使用的无线接入技术。
为了便于理解终端根据实现算法从多种无线接入技术中选择自身在直接通信接口使用的无线接入技术,下面以具体实施例进行说明。
实施例六:
对于在网的终端,比如RRC_IDLE终端、RRC_INACTIVE终端、RRC_CONNECTED终端,如果在该终端直接通信接口有数据传输需求,则终端根据该终端能力信息确定终端在直接通信接口支持的无线接入技术。
如果终端在直接通信接口仅支持一种无线接入技术,则终端在直接通信接口使用该无线接入技术进行数据的传输;如果终端在直接通信接口支持多种无线接入技术,比如既支持基于LTE Rel-14的直接通信接口无线接入技术,又支持基于NR的直接通信接口无线接入技术,则终端根据实现算法从多种无线接入技术中选择自身在直接通信接口使用的无线接入技术。
具体的,实现算法可以取决于UE实现,考虑的因素可以为:终端的直接通信业务的QoS参数、终端与网络侧设备之间的接口使用的无线接入技术等。
终端根据实现算法从多种无线接入技术中选择自身在直接通信接口使用的无线接入技术后,终端将直接通信接口使用的无线接入技术通知该网络侧设备。
相应地,网络侧设备接收终端通知的该终端在直接通信接口使用的无线接入技术,然后根据终端在直接通信接口使用的无线接入技术进行合理的资源分配。
方式七、终端根据期望使用的资源分配模式从多种无线接入技术中选择自身在直接通信接口使用的无线接入技术。
直接通信接口支持两种资源分配模式:
网络调度的资源分配模式:即由网络根据终端上报的直接通信链路(Sidelink)缓冲区上报(Buffer State Reporting,BSR)为终端分配资源的方式;
终端自主选择的资源分配方式:即终端自行从预配置或者网络广播的发送资源中选择一个资源进行直接通信链路的发送。
这里需要说明的是,对于直接通信接口,如果终端在网,无论使用网络调度的资源分配模式还是使用终端自主选择的资源分配模式,终端在直接通信接口使用的无线资源都是受网络控制的,网络侧设备通过Uu接口控制直接通信接口分配的资源池(终端自主选择的资源分配模式)或者具体资源(网络调度的资源分配模式)。
在本申请实施例中,终端期望使用的资源分配模式可以是终端自主选择的资源分配模式,也可以是网络调度的资源分配模式。
如果终端期望使用的资源分配模式是所述终端自主选择的资源分配模式,那么终端从终端支持的无线接入技术中选择任何一种无线接入技术作为自身在直接通信接口使用的无线接入技术。
比如,终端在直接通信接口支持两种直接通信接口使用的无线接入技术,基于LTE Rel-14的直接通信接口无线接入技术和基于NR的直接通信接口无线接入技术,终端根据期望使用的资源分配模式从多种无线接入技术中选择自身在直接通信接口使用的无线接入技术时,终端期望使用的资源分配模式为终端自主选择的资源分配模式,则终端可以将基于LTE Rel-14的直接通信接口无线接入技术作为终端自身在直接通信接口使用的无线接入技术,也可以将基于NR的直接通信接口无线接入技术作为终端在直接通信接口使用的无线接入技术。
如果终端期望使用的资源分配模式是网络调度的资源分配模式,那么终端将在终端与网络侧设备之间的接口使用的无线接入技术作为自身在直接通信接口使用的无线接入技术。
比如,终端在直接通信接口支持两种直接通信接口使用的无线接入技术,基于LTE Rel-14的直接通信接口无线接入技术和基于NR的直接通信接口无线接入技术,终端根据期望使用的资源分配模式从多种无线接入技术中选择自身在直接通信接口使用的无线接入技术时,终端期望使用的资源分配模式为网络调度的资源分配模式,此时终端和网络侧设备直接的接口使用的无线接入技术为基于LTE Rel-14的直接通信接口无线接入技术,则终端将基于LTE  Rel-14的直接通信接口无线接入技术作为终端在直接通信接口使用的无线接入技术。
为了便于理解终端根据期望使用的资源分配模式从多种无线接入技术中选择自身在直接通信接口使用的无线接入技术,下面以具体实施例进行说明。
实施例七:
对于在网的终端,比如RRC_IDLE终端、RRC_INACTIVE终端、RRC_CONNECTED终端,如果在该终端直接通信接口有数据传输需求,则终端根据该终端能力信息确定终端在直接通信接口支持的无线接入技术。
如果终端在直接通信接口仅支持一种无线接入技术,则终端在直接通信接口使用该无线接入技术进行数据的传输;如果终端在直接通信接口支持多种无线接入技术,比如既支持基于LTE Rel-14的直接通信接口无线接入技术,又支持基于NR的直接通信接口无线接入技术,则终端根据期望使用的资源分配模式从多种无线接入技术中选择自身在直接通信接口使用的无线接入技术。
具体的,如果终端期望使用的资源分配模式是所述终端自主选择的资源分配模式,那么终端选择任何一种无线接入技术作为自身在直接通信接口使用的无线接入技术;若终端期望使用的资源分配模式是网络调度的资源分配模式,那么终端将在所述终端与网络侧设备之间的接口使用的无线接入技术作为自身在直接通信接口使用的无线接入技术。
终端根据期望使用的资源分配模式从多种无线接入技术中选择自身在直接通信接口使用的无线接入技术后,终端将直接通信接口使用的无线接入技术通知该网络侧设备。
相应地,网络侧设备接收终端通知的该终端在直接通信接口使用的无线接入技术,然后根据终端在直接通信接口使用的无线接入技术进行合理的资源分配。
方式八、终端将网络侧设备通知的无线接入技术作为自身在直接通信接口使用的无线接入技术。
在实施中,网络侧设备通知终端在直接通信接口使用哪种无线接入技术, 则网络侧设备需要确定终端在直接通信接口使用哪种无线接入技术,所以首先终端通知网络侧设备终端在直接通信接口支持的无线接入技术,比如终端在直接通信接口支持两种无线接入技术,基于LTE Rel-14的直接通信接口无线接入技术和基于NR的直接通信接口无线接入技术;
网络侧设备接收到终端通知的终端在直接通信接口支持的无线接入技术后,确定终端在直接通信接口使用的无线接入技术,比如网络侧设备确定终端在直接通信接口使用的无线接入技术为基于LTE Rel-14的直接通信接口无线接入技术;
网络侧设备将确定的终端在直接通信接口使用的无线接入技术通知给终端,终端接收到网络侧设备通知的终端在直接通信接口使用的无线接入技术后,将该无线接入技术作为终端在直接通信接口使用的无线接入技术。
需要说明的是,网络侧设备通知终端在直接通信接口使用的无线接入技术时,可以通过显式方式指示的无线接入技术作为在直接通信接口的无线接入技术,也可以通过资源分配指示信息隐式方式指示的无线接入技术作为在直接通信接口的无线接入技术。
为了便于理解终端将网络侧设备通知的无线接入技术作为自身在直接通信接口使用的无线接入技术,下面以具体实施例进行说明。
实施例八:
终端通过终端能力为网络侧设备上报该终端在直接通信接口使用的无线接入技术。
对于在网的终端,比如RRC_IDLE终端、RRC_INACTIVE终端、RRC_CONNECTED终端,如果在该终端直接通信接口有数据传输需求,则终端根据该终端能力信息确定终端在直接通信接口支持的无线接入技术。
如果终端在直接通信接口仅支持一种无线接入技术,则终端在直接通信接口使用该无线接入技术进行数据的传输;如果终端在直接通信接口支持多种无线接入技术,比如既支持基于LTE Rel-14的直接通信接口无线接入技术,又支持基于NR的直接通信接口无线接入技术,则终端将网络侧设备通知的无 线接入技术作为自身在直接通信接口使用的无线接入技术。
具体的,网络侧设备通知终端在直接通信接口使用的无线接入技术可以采用显式方式,也可以采用隐式方式。
对于显式方式通知,即网络侧设备直接指示终端在直接通信接口使用的无线接入技术;
比如对于在网的终端,RRC_IDLE终端、RRC_INACTIVE终端、RRC_CONNECTED终端,该指示信息可以携带在广播消息中,比如主系统信息块(Master Information Block,MIB)、系统信息块1(System Information Block 1,SIBI)、直接通信相关的系统信息块(System Information Block,SIB)中,对于RRC_CONNECTED终端,还可以携带在专用信令中。
对于隐式方式通知,即网络侧设备通过资源分配指示信息隐式指示终端在直接通信接口可以使用的无线接入技术,比如资源分配指示信息的格式。
网络侧设备确定了终端在直接通信接口使用的无线接入技术后,根据终端在直接通信接口使用的无线接入技术进行合理的资源分配。
