Description

通信控制方法、用户设备和基站 技术领域
本发明实施例涉及通信技术,尤其涉及一种通信控制方法、用户设备和基站。
背景技术
一般地,在蜂窝通信技术中,用户设备一般是通过基站的转发实现通信,即用户设备通过空口与基站进行通信,通过基站将用户数据转发到网络中的目的节点。但是,在蜂窝通信中,由于无线频谱资源的紧张,如何提高频谱资源的利用率成为研究热点。
为此,一种新的无线接口技术,终端与设备(Device-to-Device,简称D2D)通信被提出。D2D通信是一种允许用户设备之间通过复用小区资源直接进行通信的新型通信技术,它能够增加蜂窝通信系统频谱效率,缓解基站负载,在一定程度上解决了无线通信系统频谱资源匮乏的问题。
当前,D2D通信支持组播通信(即1-to-many通信),即D2D用户设备(User Equipment,简称UE)可以发送D2D数据到某个通信组的若干UE。目前,对于D2D通信来说,主要的研究热点集中在组播通信方面。但是,实际应用中,还会存在单播通信(即1-to-1通信)的需求,即一个UE通过D2D通信方式与另一个UE进行通信。在该需求下,基站如何实现对需要进行单播D2D通信的用户设备的控制,成为亟待解决的问题。

具体实施方式
为使本发明实施例的目的、技术方案和优点更加清楚,下面将结合本发明实施例中的附图,对本发明实施例中的技术方案进行清楚、完整地描述,显然,所描述的实施例是本发明一部分实施例,而不是全部的实施例。基于本发明中的实施例,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他实施例,都属于本发明保护的范围。
图1为本发明实施例提供的一种通信场景示意图,本发明的方案可以应用于用户设备之间进行D2D通信的场景,尤其适用于进行第一通信即单播通信方式的D2D亦即一对一(one-to-one)方式的D2D通信场景或者中继通信方式的D2D亦即用户设备到网络的中继通信(UE-to-Network Relay)的D2D通信场景。适用于本发明的方案的通信网络可以是长期演进(Long Term Evolution,简称LTE)网络,相应的,在LTE网络中,图1所示的基站可以是演进型基站(evolved Node B,简称eNB)。如图1所示,假设UE A想要进行与UE B的第一通信,UE A首先需要从eNB中获取相应的第一通信资源即单播通信资源或中继通信资源,进而使用该第一通信资源进行与UE B间的第一通信。
图2为本发明实施例提供的通信控制方法实施例一的流程图,如图2所示,在图1所示的通信场景的基础上,该方案的执行主体为UE A,该通信控制方法的具体步骤包括:
步骤101:UE A确定是否需要进行第一通信,若需要进行第一通信,则执行步骤102,否则,结束。
本实施例中,对于UE A来说,其用户在需要进行与另一用户(其对应的用户设备为UE B)间的通信时,在一种具体实现中,该用户可以通过APP的方式来选择采用何种具体的通信方式来进行该次通信。可选的,在APP界面中可选的通信方式比如包括:基站转发方式、组播D2D方式、单播D2D方式、中继通信方式、WIFI方式等等。当UE A接收到的是用户选择了第一通信方式时所触发的对应指令时,确定当前需要进行与UE B的第一通信。
步骤102:UE A从基站中获取进行所述第一通信所需的第一通信资源,采用所述第一通信资源进行第一通信。
本实施例中,在UE A需要与UE B进行第一通信即单播D2D通信或中继通信时,UE A可通过其对应的基站来获取相应的第一通信资源即单播通信资源或中继通信资源。也就是说,由覆盖UE A的基站来负责对UE A的单播D2D通信或中继通信进行控制,包括为其分配单播通信或中继通信的资源。
在基站覆盖范围内的具有第一通信功能的用户设备需要进行第一通信时,可以从该覆盖基站获取相应的第一通信资源,实现了覆盖基站对用户设备第一通信的资源分配控制。
UE A可以根据其自身所处的无线资源控制(Radio Resource Control,简称RRC)状态来确定从基站获取第一通信资源的方式。
具体来说,可选的,上述步骤102中,UE A从基站中获取进行第一通信所需的第一通信资源,可以通过如下方式中的任一种实现:
若UE A处于RRC空闲态,则UE A根据监听到的基站广播的系统消息块(System Information Block,简称SIB)获取第一通信资源;
或者,
若UE A处于RRC空闲态,则进入RRC连接态,向基站发送第一通信资源请求用于请求所述基站分配第一通信资源;
或者,
若UE A处于RRC连接态,则向基站发送第一通信资源请求。
本实施例中,用户设备可以根据第一通信资源的使用模式来获取第一通信资源,用户设备第一通信资源的使用模式,包括共享模式和独立模式,其中:共享模式即第一通信资源可以与第二通信资源共享;独立模式即第一通信资源与第二通信资源是独立使用的。
也就是说,用户设备UE A可以通过独立模式或者共享模式从基站获取第一通信资源。其中,所述第二通信资源是进行第二通信时对应的通信资源,文中所述第二通信是指组播D2D通信,即one-to-many的D2D通信,相应的,文中所述第二通信资源池为组通信资源池。
其中,所述第一通信资源的使用模式通过协议规定,或者通过RRC消息配置。
下面结合几个具体的实施例来介绍上述几种可选的实现方式。
图2a为图2所示实施例中步骤102的一种具体实现方式的信令图,在UE A处于RRC空闲态时,UE A可以根据如图2a所示的方式,通过监听基站广播的SIB获取第一通信资源。
具体地,若第一通信资源的使用模式是共享模式,基站可以广播SIB,该SIB中包含用于第二通信的第二通信资源池,且包括指示UE A使用该第二通信资源池进行第一通信的指示消息。从而,UE A在监听到该SIB时,根据该SIB中所包含的上述指示消息,在该第二通信资源池中选择第一通信资源,此时,UEA仍保持在空闲态。
其中,组通信资源池中包括可以用于进行组播D2D通信的多个物理资源块,UE A可以根据其所需发送的D2D数据的大小确定所需的物理资源块的数量,从中选择出相应数量的物理资源块作为其进行第一通信的第一通信资源。
本实施例中,基站能够控制第一通信复用组播D2D通信即第二通信的资源,在网络负载较重的情况下,尤其能够提高资源利用率。
图2b为图2所示实施例中步骤102的另一种具体实现方式的信令图,在UE A处于RRC空闲态时,UE A可以根据如图2b所示的方式,通过监听基站广播的SIB获取第一通信资源。
具体地,若第一通信资源的使用模式是独立模式,基站可以广播SIB,该SIB中包含用于进行第一通信的第一通信资源池。从而,UE A在监听到该SIB时,可以从该第一通信资源池中选择第一通信资源,此时,UEA仍保持在空闲态。
值得说明的是,为了与现有协议标准兼容,在该SIB中可以包括两个资源池,一个是现有协议标准中的组通信资源池,另一个是上述第一通信资源池即单播通信资源池或中继通信资源池。可以理解的是,为了使得用户设备能够 区别这两个资源池,每个资源池会有相应的标识,从而UE A在监听到该SIB时,可以从第一通信资源池中选择第一通信资源。
可以理解的是,上述第二通信资源池和第一通信资源池中所包含的物理资源块没有重叠,即基站为组播D2D通信和第一通信分别分配不同的资源池,与图2a中两种D2D通信可以共享资源的方式相反。
同样的,UE A可以根据其所需发送的D2D数据的大小确定所需的物理资源块的数量,从第一通信资源池中选择出相应数量的物理资源块作为其进行第一通信的第一通信资源。
本实施例中,基站为第一通信分配独立的第一通信资源池,可以一定程度上避免D2D用户设备间的相互干扰,可以更好保证第一通信的质量,尤其适用于网络负载较轻的情况。
图2c为图2所示实施例中步骤102的又一种具体实现方式的信令图,在UE A处于RRC空闲态时,UE A可以根据如图2c所示的方式,通过进入连接态,向基站发送第一通信资源请求的方式来获取第一通信资源。
具体地,若第一通信资源的使用模式是共享模式,基站广播SIB,该SIB中没有提供用于第二通信的第二通信资源池或第一通信的第一通信资源池,从而,UE A在监听到该SIB时,进入RRC连接态,向基站发送第一通信资源请求来获取第一通信资源。
图2d为图2所示实施例中步骤102的再一种具体实现方式的信令图,在UE A处于RRC空闲态时,UE A可以根据如图2d所示的方式,通过进入连接态,向基站发送第一通信资源请求的方式来获取第一通信资源。
具体地,若第一通信资源的使用模式是独立模式,基站广播SIB,该SIB中没有提供用于第一通信的第一通信资源池,此时,UE A在监听到该SIB时,进入RRC连接态,并向基站发送所述第一通信资源请求。
图2e为图2所示实施例中步骤102的还一种具体实现方式的信令图,在UE A处于RRC空闲态时,UE A可以根据如图2d所示的方式,通过进入连接态,向基站发送第一通信资源请求的方式来获取第一通信资源。
具体地,若第一通信资源的使用模式是独立模式,基站可以广播SIB,该SIB中包含用于第二通信的第二通信资源池,且,不包括指示UE A使用该组通信资源池进行第一通信的指示消息或包括指示UE A不可以使用所述第二 通信资源池进行第一通信的指示消息。从而,UE A在监听到该SIB时,进入RRC连接态,向基站发送第一通信资源请求来获取第一通信资源。
也就是说,当UE A监听到的SIB中仅包含有组通信资源池,或者包含有组通信资源池和指示不可以用该组通信资源池进行第一通信的指示消息时,UE A进入RRC连接态,向基站发送第一通信资源请求。
图2f为图2所示实施例中步骤102的还一种具体实现方式的信令图,在UE A处于RRC空闲态时,UE A可以根据如图2f所示的方式,通过进入连接态,向基站发送第一通信资源请求的方式来获取第一通信资源。
具体地,基站可以广播SIB,该SIB中包括指示UE A进入RRC连接态,向基站发送第一通信资源请求来获取第一通信资源的指示消息。从而,UE A在监听到该SIB时,根据该指示消息进入RRC连接态,向基站发送第一通信资源请求。
图2g为图2所示实施例中步骤102的还一种具体实现方式的信令图,在UE A处于RRC空闲态时,UE A可以根据如图2g所示的方式,通过进入连接态,向基站发送第一通信资源请求的方式来获取第一通信资源。
具体地,UE A在确定需要进行第一通信时,直接进入连接态,向基站发送第一通信资源请求的方式来获取第一通信资源。
上述图2c至图2g的实施例中,当UE A处于RRC空闲态时,既可以根据默认设置,在确定需要进行第一通信时,直接进入RRC连接态,也可以根据监听到的SIB中的指示进入连接态的指示来进入RRC连接态,还可以在监听到的SIB中不包含第一通信资源池时进入RRC连接态,在进入RRC连接态之后,可以通过向基站请求的方式来请求基站为其分配第一通信资源。从而,基站基于上述不同的控制方式,可以实现对用户设备第一通信的通信资源分配的控制。
在上述图2c至图2g的实施例的基础上,当UE A向基站发送了第一通信资源请求后,基站可以采用如下的几种可选实现方式进行相应的响应处理:
图3a为图2c至图2g中UE A进入RRC连接态后,UE A的一种获取第一通信资源的信令图,如图3a所示,UE A进入连接态之后,向基站发送第一通信资源请求。具体的,该第一通信资源请求中可以包括UE A所需发送 的数据的大小等信息。
基站接收到该第一通信资源请求后,可以通过专用信令,如第一RRC信令或第一媒介接入控制单元(Medium Access Control Element,简称MAC CE)向UE A发送指示UE A使用第二通信的第二通信资源池进行第一通信的指示消息,进而,UE A根据该指示消息,从第二通信资源池中选择第一通信资源。
值得说明的是,基站预先已经进行了第二通信资源(即组播D2D通信资源)的分配,且UE A已经获取到该第二通信资源池(即组通信资源池),当UE A向基站请求第一通信所需的第一通信资源时,若接收到基站反馈的上述指示消息,则说明UE A可以复用组通信资源作为第一通信资源。UE A可以根据所需发送数据的大小,从组通信资源池中选择相应数量的物理资源块作为第一通信资源使用,本文中,第一通信包含单播(one-to-one)D2D通信和中继通信,第一通信资源包括单播通信资源和中继通信资源,第二通信可以为组播D2D通信。
图3b为图2c至图2g中UE A进入RRC连接态后,UE A的另一种获取第一通信资源的信令图,如图3b所示,UE A进入连接态之后,向基站发送第一通信资源请求。基站接收到该第一通信资源请求后,可以通过专用信令,如第二RRC信令或第二MAC CE向UE A发送指示UE A重用侧行无线网络临时标识(SideLink-Radio Network Temporary Identity,简称SL-RNTI)获取第一通信资源的指示消息,UE A进而根据SL-RNTI获取基站分配的第二通信资源,并以该第二通信资源作为第一通信资源,进行第一通信。
其中,SL-RNTI是用于调度第二通信即组播D2D通信的通信资源的RNTI,也就是说,该SL-RNTI是在基站为UE A分配组通信资源时所采用的RNTI。因此,基站通过发送该指示消息,意味着指示UE A继续使用该SL-RNTI获取基站分配的组通信资源来用作第一通信资源。
上述图3a和图3b两种方式,基站仍旧是指示UE A复用之前分配的组通信资源来进行第一通信。
图3c为图2c至图2g中UE A进入RRC连接态后,UE A的又一种获取第一通信资源的信令图,如图3c所示,UE A进入连接态之后,向基站发送第一通信资源请求。基站接收到该第一通信资源请求后,可以通过专用信令,如第四RRC信令或第四MAC CE向UE A发送第一通信资源池,UE A进 而从该第一通信资源池中选择第一通信资源。其中,该第一通信资源池是基站分配的专用于进行第一通信的资源池。
图3d为图2c至图2g中UE A进入RRC连接态后,UE A的再一种获取第一通信资源的信令图,如图3d所示,UE A进入连接态之后,向基站发送第一通信资源请求。基站接收到该第一通信资源请求后,可以通过专用信令,如第五RRC信令或第五MAC CE向UE A发送新的无线网络临时标识,可以记为New-RNTI,可选的,还可以通过物理下行控制信道(Physical Downlink Control Channel,简称PDCCH)或增强的物理下行控制信道(enhanced PDCCH,简称ePDCCH)向UE A发送经该New-RNTI加扰的调度信息,其中,所述New-RNTI是用于调度第一通信的通信资源的RNTI,所述调度信息中包括基站为第一通信调度的第一通信资源。进而,UE A根据New-RNTI获取第一通信资源。即New-RNTI是用于调度第一通信的通信资源的RNTI,所述调度信息中包括基站为第一通信调度的第一通信资源。
值得说明的是,上述图3c至图3d所示实施例中,当基站接收到UE A发送的第一通信资源请求后,可以先判断是否准许UE A进行该第一通信,判断的依据比如可以是当前的资源是否足够。如果足够,可以准许UE A进行第一通信,为UE A分配第一通信资源。相反的,如果不足够,则不准许UE A进行第一通信,相应的,可以通过RRC信令或MAC CE向UE A发送资源拒绝消息,或者不为UE A分配资源。
具体来说,基站通过第三RRC信令或第三MAC CE向UE A发送资源拒绝消息,其中,所述资源拒绝消息包括资源拒绝指示,所述资源拒绝指示用于指示UE A禁止使用第二通信资源池,和/或,指示UE A禁止使用已分配的用于调度所述第二通信的通信资源的SL-RNTI。从而,UE A根据该资源拒绝指示不使用第二通信资源池进行第一通信,或者,不适用SL-RNTI调度相应资源进行第一通信。或者,若UE A没有接收到基站的资源分配的信息,则确定不能进行所述第一通信。
上述各实施例可以适用于如图1所示的一种普通的通信场景中,该场景下,UE A作为支持D2D通信的用户设备,在其需要进行第一通信时,触发上述处理过程。下面,结合另一种特殊的第一通信场景,介绍一个特殊的第 一通信方式——中继通信。
图4为本发明实施例提供的另一种通信场景示意图,如图4所示,假设UE A和UE C都支持D2D通信尤其是支持第一通信,UE A位于基站的覆盖范围内,且处于其覆盖范围的边缘,此时,由于UEA位于基站覆盖范围边缘,存在较大的不能接入到基站中的风险,此时,UE A为远程用户设备,即Remote UE A。假设UE C可以提供中继服务,UE A可以通过UE C接入基站,此时,UE C为中继用户设备,即Relay UE C。Remote UE A与Relay UE C之间的第一通信即中继通信。
图5为本发明实施例提供的通信控制方法实施例二的流程图,如图5所示,在图4所示的通信场景的基础上,该方案的执行主体为UE A,该通信控制方法的具体步骤包括:
步骤201:UE A判断接收基站发送参考信号的参考信号接收强度是否低于预设阈值,若低于预设阈值,则执行步骤202,否则结束。
其中,如果UE A接收到的基站发送的参考信号的参考信号接收强度低于预设阈值,说明该UE A很可能处于基站覆盖范围的边缘,其很可能无法通过基站实现蜂窝通信。
步骤202:UE A确定需要进行中继通信,UE A发送通信请求消息,所述通信请求消息用于请求具有中继通信服务功能的用户设备反馈响应消息。
步骤203:UE A根据各具有中继通信服务功能的用户设备反馈的响应消息的接收信号强度,从各具有中继通信服务功能的用户设备中选择出UE C。
其中,UE C对应的响应消息的接收信号强度最高,UE C用于为UE A提供中继通信服务即中继服务。
在UE A确定处于基站覆盖边缘,无法通过基站实现蜂窝通信时,触发UE A采用中继通信的方式接入基站。
为此,UE A首选需要在小区中提供中继服务的众多中继用户设备中选择出为其提供中继服务的用户设备。具体地,UE A可以发送一条中继请求消息即上述通信请求消息,该中继请求消息用于请求具有中继服务功能的中继用户设备反馈响应消息。从而,UE A根据各中继用户设备反馈 的响应消息的接收信号强度,从各中继用户设备中选择出接收信号强度最高的UE C作为其中继用户设备。
值得说明的是,关于多个中继用户设备,该中继用户设备既然能够提供中继功能,说明其相对于基站的接收功率一般大于一定阈值。
步骤204:UE A从基站获取进行中继通信所需的第一通信资源,并使用该第一通信资源与UE C进行中继通信。
UE A选择出中继用户设备UE C之后,可以采用根据前述各实施例的方式,获得上述第一通信资源,进而使用该第一通信资源与UE C进行中继通信,即将其所要发送的数据,通过UE C发送至基站。
本实施例中,当支持D2D通信的用户设备处于某基站的覆盖边缘而无法接入基站进行蜂窝通信时,触发该用户设备的中继通信过程,通过该中继通信过程,保证了该用户设备的数据的成功发送,且由于该中继通信属于D2D通信,该用户设备与中继用户设备间使用第一通信资源的通信,还可以提高资源利用率。
图6为本发明实施例提供的通信控制方法实施例三的流程图,如图6所示,在图1或图4所示的通信场景的基础上,该方案的执行主体是UE A,该通信控制方法的具体步骤包括:
步骤301:UE A向基站上报测量事件,所述测量事件指示UE A接收基站的链路质量和/或信号强度满足一定条件。
步骤302:UE A接收基站通过RRC信令或MAC CE发送的信息。
其中,所述信息用于指示UE A停止第一通信或者停止使用第一通信的资源和/或停止使用配置的用于调度第一通信的通信资源的New-RNTI和/或停止使用配置的用于调度第二通信的通信资源的SL-RNTI,其中,第一通信的资源包括第一通信资源池和第二通信资源池;
步骤303:UE A执行所述信息。
即UE A根据所述信息,停止第一通信或者停止使用第一通信的资源和/或停止使用配置的用于调度第一通信的通信资源的New-RNTI和/或停止使用配置的用于调度第二通信的通信资源的SL-RNTI。
本实施例中,在用户设备采用第一通信的方式进行第一通信的情况下, 基站可以控制用户设备停止继续采用第一通信方式进行通信。
具体来说,比如基站可以在检测到自身的无线资源紧张或者负载过重,可以控制用户设备停止采用第一通信方式进行通信,从而降低自身的负荷,此时,上述步骤301为可选步骤。
另外,UE A使用第一通信资源与UE B进行通信,或者在通过UE C接入网络之后,在测量到上述测量事件时,向基站上报该测量事件。该测量事件表明UE A与基站的信道质量良好,可以通过基站进行蜂窝通信,不必再通过UE C中继入网或者与UE B进行单播D2D通信。此时,触发基站控制UE A停止继续采用第一通信方式进行通信。
此外,基站还可以基于用户设备UE A上报的测量结果来决定是否控制UE A停止继续采用第一通信方式进行通信。具体地,以图4场景为例,UE A可以在通过UE C接入网络之后,周期性检测比如参考信号接收功率(RSRP)和/或参考信号接收质量(Reference Signal Receiving Quality,简称RSRQ),并将测量结果上报给基站。基站根据测量结果确定相应的PSRP、RSRQ满足一定条件即大于一定阈值时,控制UE A停止继续采用中继通信方式进行通信。
值得说明的是,基站可以依据上述测量事件和测量结果中的一个做出上述控制停止第一通信的控制决定,也可以依据两者做出上述控制停止第一通信的控制决定,即只有既满足测量事件,测量结果又满足一定条件时,做出控制停止第一通信的控制决定。
对于图4场景中的UE A来说,由于其在基站覆盖边缘时,无法通过基站实现蜂窝通信而采用中继通信,如果基站基于UE A的测量事件或测量结果发现UE A的接收功率已经大于一定阈值或信号强度已经大于一定阈值,其已经移动至覆盖范围内部,此时可以控制UE A停止中继通信,因为UE A已经可以通过基站进行蜂窝通信。对于UE C来说,基站可以在检测到UE C的中继负载很轻时,控制UE C停止中继通信,以避免不能充分利用第一通信资源。
具体地,基站可以通过专用信令如RRC信令或MAC CE向用户设备发送上述信息。
其中,MAC CE包括特定的逻辑信道索引值标识的MAC PDU子头;或者,MAC CE包括被停止第一通信的所述用户设备UE A的标识和/或指示UE A停止第一通信的指示信息。
其中,MAC CE可以设计如下表,使用MAC分组数据单元(packet data unit,简称PDU)子头的索引(index)和逻辑信道标识(logical channel identify,简称LCID)值来实现停止中继通信的目的。
index LCID
00000 保留
00001-01010 逻辑信道标识
01011 停止中继命令
01100-11110 保留
11111 填充
以上实施例,还可用于基站停止进行单播通信的用户设备的单播通信链路。
本实施例中,基站基于自身资源情况、负载情况或基于检测到的用户设备的网络接入情况,可以控制进行第一通信的用户设备停止使用第一通信方式进行通信或控制用户设备禁止使用上述相关资源进行第一通信。
图7为本发明实施例提供的通信控制方法实施例四的流程图,如图7所示,在图1或图4所示的通信场景的基础上,该方案的执行主体是UE A,该通信控制方法的具体步骤包括:
步骤401:UE A接收所述基站通过PDCCH或ePDCCH发送的经SL-RNTI或New-RNTI加扰的授权消息,所述授权消息中包括指示停止第一通信的指示消息。
其中,所述SL-RNTI是用于调度第二通信即组播D2D通信的通信资源的RNTI,所述New-RNTI是用于调度第一通信的通信资源的RNTI。
其中,上述授权消息是指用于进行资源分配的授权消息。
步骤402:UE A根据对应的SL-RNTI或New-RNTI获取所述指示停止第一通信的指示消息,停止进行第一通信。
本实施例中,在用户设备采用第一通信的方式进行第一通信的情况下,基站可以控制用户设备停止继续采用第一方式进行通信。
其中,基站做出上述停止第一通信的决定的条件与前述实施例一致,不 赘述。与前述实施例的区别在于基站控制用户设备停止第一通信的方式不同。
具体地,基站可以通过PDCCH或ePDCCH向用户设备发送经SL-RNTI或New-RNTI加扰的授权消息,所述授权消息中包括指示停止第一通信的指示消息。
值得说明的是,该SL-RNTI和New-RNTI是与用户设备对应的,即如果用户设备为UE A,则该SL-RNTI和New-RNTI是与UE A对应的。
另外,该SL-RNTI和New-RNTI也与基站为用户设备分配第一通信资源的方式相关,如果基站为用户设备分配第一通信资源的方式是指示用户设备根据SL-RNTI获取第一通信资源,即指示用户设备复用组播通信资源,则在其停止用户设备的第一通信时,向用户设备发送的便是该SL-RNTI;如果基站为用户设备分配第一通信资源的方式是指示用户设备根据New-RNTI获取第一通信资源,即指示用户设备根据该New-RNTI获取基站为其分配的独立的第一通信资源,则在其停止用户设备的第一通信时,向用户设备发送的便是该New-RNTI。
用户设备在接收到该授权消息后,根据其获取第一通信资源时所对应的SL-RNTI或New-RNTI获取该授权消息中包含的上述指示停止第一通信的指示消息,根据该指示消息停止进行第一通信。
本实施例中,基站基于自身资源情况、负载情况或基于检测到的用户设备的网络接入情况,可以控制进行第一通信的用户设备停止使用第一通信方式进行通信。
上述各实施例都是从用户设备作为执行主体的角度进行的描述,下面,将从基站作为执行主体的角度说明基站的处理过程。
本发明的方案中,基站可以为需要进行第一通信的用户设备分配进行第一通信所需的第一通信资源,以使用户设备使用该第一通信资源进行第一通信。
具体来说,基站可以通过广播SIB的方式或者通过用户设备请求分配第一通信资源的方式为需要进行第一通信的用户设备分配第一通信资源。
可选的,基站广播携带有第一通信资源的SIB,以使处于RRC空闲态的用户设备根据该SIB获取第一通信资源。
或者,可选的,基站接收处于RRC连接态的用户设备发送的第一通信资源请求,基站根据该第一通信资源请求为处于RRC连接态的用户设备分配第一通信资源。
值得说明的是,本发明实施例中,在不引起歧义的情况下,用户设备都是指需要进行第一通信的用户设备,而不是通过蜂窝通信的用户设备。而且,本实施例中,第一通信为单播D2D通信或者中继通信,第二通信为组播D2D通信。相应的,第一通信资源为单播通信资源或中继通信资源,下述第二通信资源池为组通信资源池,即用于进行组播D2D通信的通信资源池。
而且,本实施例中,基站可以根据第一通信资源的使用模式为用户设备分配进行第一通信所需的第一通信资源,所述第一通信资源的使用模式,包括共享模式和独立模式,其中:共享模式即第一通信资源可以与第二通信资源共享;独立模式即第一通信资源与第二通信资源是独立使用的。所述第一通信资源的使用模式通过协议规定,或者通过RRC消息配置。
下面,结合几个具体的实现方式介绍基站的第一通信资源分配的处理过程:
方式一:若第一通信资源的使用模式是共享模式,基站广播第一SIB,第一SIB中包括用于第二通信的第二通信资源池,且包括指示用户设备使用组通信资源池进行第一通信的指示消息。
从而,RRC空闲态的用户设备在监听到该第一SIB后,从该第二通信资源池中选择第一通信资源,且该用户设备依旧保持在RRC空闲态。
该方式一对应于图2a所示的实施例,具体的处理过程不再赘述。
方式二:若第一通信资源的使用模式是独立模式,基站广播第二SIB,第二SIB中包括用于进行第一通信的第一通信资源池。
从而,处于RRC空闲态的用户设备在监听到该第二SIB后,从第一通信资源池中选择第一通信资源,且该用户设备依旧保持在RRC空闲态。
该方式二对应于图2b所示的实施例,具体的处理过程不再赘述。
方式三:若第一通信资源的使用模式是共享模式,基站广播第三SIB,第三SIB中没有提供用于第二通信的第二通信资源池或第一通信的第一通信 资源池。
从而,处于RRC空闲态的用户设备在监听到第三SIB后,进入RRC连接态,并向基站发送所述第一通信资源请求。
该方式三对应于图2c所示的实施例,具体的处理过程不再赘述。
方式四:若第一通信资源的使用模式是独立模式,基站广播第四SIB,第四SIB中没有提供用于第一通信的第一通信资源池。
从而,处于RRC空闲态的用户设备在监听到第四SIB后,进入RRC连接态,并向基站发送所述第一通信资源请求。
该方式四对应于图2d所示的实施例,具体的处理过程不再赘述。
方式五:若第一通信资源的使用模式是独立模式,基站广播第五SIB,第五SIB中包括用于第二通信的第二通信资源池,且不包括指示用户设备使用第二通信资源池进行第一通信的指示消息或包括指示用户设备不可以使用第二通信资源池进行第一通信的指示消息。
从而,处于RRC空闲态的用户设备在监听到该第五SIB后,进入RRC连接态,向基站发送所述第一通信资源请求,以请求基站为其分配第一通信资源。
该方式五对应于图2e所示的实施例,具体的处理过程不再赘述。
方式六:基站广播第六SIB,第六SIB中包括指示用户设备进入RRC连接态,向基站发送第一通信资源请求以获取第一通信资源的指示消息。
从而,处于RRC空闲态的用户设备在监听到该第六SIB后,进入RRC连接态,向基站发送第一通信资源请求。
该方式六对应于图2f所示的实施例,具体的处理过程不再赘述。
方式七:处于RRC空闲态的用户设备直接进入RRC连接态,向基站发送第一通信资源请求。
该方式七对应于图2g所示的实施例,具体的处理过程不再赘述。
在方式三至方式六中,用户设备从RRC空闲态进入RRC连接态,向基站发送第一通信资源请求之后,或者,开始便处于RRC连接态的用户设备直接向基站发送第一通信资源请求之后,基站根据该第一通信资源请求为处于RRC连接态的用户设备分配第一通信资源,具体实现方式包括:
方式1:基站通过第一RRC信令或第一MAC CE向用户设备发送指示用 户设备使用第二通信的第二通信资源池进行第一通信的指示消息。
从而,用户设备从该第二通信资源池中选择第一通信资源。
该方式1对应于图3a所示的实施例,具体的处理过程不再赘述。
方式2:基站通过第二RRC信令或第二MAC CE向用户设备发送指示用户设备重用SL-RNTI获取第一通信资源的指示消息。
其中,所述SL-RNTI是用于调度第二通信的通信资源的RNTI。
从而,用户设备根据该SL-RNTI获取基站分配的第二通信资源,并以该第二通信资源作为第一通信资源。
该方式2对应于图3b所示的实施例,具体的处理过程不再赘述。
方式3:基站通过第四RRC信令或第四MAC CE向用户设备发送第一通信资源池。
从而,用户设备从第一通信资源池中选择第一通信资源。
该方式3对应于图3c所示的实施例,具体的处理过程不再赘述。
方式4:基站通过第五RRC信令或第五MAC CE向用户设备发送New-RNTI。
其中,所述New-RNTI是用于调度第一通信的通信资源的RNTI。
从而,用户设备根据New-RNTI获取第一通信资源。
该方式4对应于图3d所示的实施例,具体的处理过程不再赘述。
值得说明的是,基站在根据第一通信资源请求为处于RRC连接态的用户设备分配所述第一通信资源之前,可以先判断是否准许UE A进行该第一通信,判断的依据比如可以是当前的资源是否足够。如果足够,可以准许UE A进行第一通信,为UE A分配第一通信资源。相反的,如果不足够,则不准许UE A进行第一通信,相应的,可以通过RRC信令或MAC CE向UE A发送资源拒绝消息,或者不为UE A分配资源。
具体来说,基站通过第三RRC信令或第三MAC CE向UE A发送资源拒绝消息,其中,所述资源拒绝消息包括资源拒绝指示,所述资源拒绝指示用于指示UE A禁止使用第二通信资源池,和/或,指示UE A禁止使用已分配的用于调度所述第二通信的通信资源的SL-RNTI。从而,UE A根据该资源拒绝指示不使用第二通信资源池进行第一通信,或者,不使用SL-RNTI获取相应资源进行第一通信。或者,若UE A没有接收到基站的资源分配的信息,则确定 不能进行所述第一通信。
上述各种实现方式,均是说明基站为用户设备分配第一通信资源的实现方式。其所适用于的通信场景可以如图1或图4所示,其中,该用户设备对应于UE A或UE C。在图4的场景中,第一通信具体为中继通信。其中,UE A在确定其接收基站发送参考信号的参考信号接收强度低于预设阈值时,确定需要进行中继通信。从而可参考前述各种实现方式,获得用户进行该中继通信所需的第一通信资源,以与UE C进行中继通信。图4中,UE C获取第一通信资源的方式与UE A获得第一通信资源的方式相同。
基站除了可以为用户设备分配第一通信资源,实现对第一通信的资源控制之外,还可以通过停止用户设备的第一通信实现对用户设备第一通信的控制。
以下,基于图1或图4所示的通信场景,说明基站如何控制用户设备停止第一通信。
针对上述通信场景中的UE A来说,UE C同理,不重复说明,可以通过如下方式a或方式b实现对其第一通信的停止控制:
方式a:基站通过RRC信令或MAC CE向UE A发送信息。
其中,该信息用于指示UE A停止第一通信或者停止使用第一通信的资源和/或停止使用配置的用于调度第一通信的通信资源的New-RNTI和/或停止使用配置的用于调度第二通信的通信资源的SL-RNTI,其中,第一通信的资源包括第一通信资源池和第二通信资源池。
从而,UE A执行该信息。
该方式a对应于图6所示的实施例,具体的处理过程不再赘述。
方式b:基站通过PDCCH或ePDCCH向UE A发送经SL-RNTI或New-RNTI加扰的授权消息,所述授权消息中包括指示停止第一通信的指示消息。
所述SL-RNTI是用于调度第二通信的通信资源的RNTI,所述New-RNTI是用于调度第一通信的通信资源的RNTI。从而UE A在根据对应的SL-RNTI或New-RNTI获取指示停止第一通信的指示消息时,停止进行第一通信。
其中,当向UE A发送该授权消息时,SL-RNTI和New-RNTI是与UE A对应的;当向UE C发送该授权消息时,SL-RNTI和New-RNTI是与UE C对应的。
该方式b对应于图7所示的实施例,具体的处理过程不再赘述。
值得说明的是,在上述方式a、b中,基站可以基于如下的方式来决定是否执行方式a、b。
具体来说,比如基站可以在检测到自身的无线资源紧张或者负载过重,可以控制用户设备停止采用第一通信方式进行通信,从而降低自身的负荷。
另外,基站也可以基于用户设备(UE A、UE C)上报的测量事件和/或测量结果决定否执行方式a、b。
具体来说,以图4所示通信场景中的UE A为例,UE A在通过UE C接入网络之后,在测量到上述测量事件时,向基站上报该测量事件。该测量事件表明UE A与基站的信道质量良好,可以通过基站进行蜂窝通信,不必再通过UE C中继入网。此时,触发基站控制UE A停止继续采用第一通信方式进行通信。
此外,基站还可以基于用户设备UE A上报的测量结果来决定是否控制UE A停止继续采用第一通信方式进行通信。具体地,UE A可以在通过UE C接入网络之后,周期性检测比如RSRP和/或参考信号接收质量RSRQ,并将测量结果上报给基站。基站根据测量结果确定相应的PSRP、RSRQ满足一定条件即大于一定阈值时,控制UE A停止继续采用第一通信方式进行通信。
图8为本发明实施例提供的用户设备实施例一的结构示意图,如图8所示,该用户设备用于在需要进行第一通信时,从基站获取进行所述第一通信所需的第一通信资源,该用户设备包括:第一获取模块11,或者该用户设备包括状态转换模块12和发送模块13。
第一获取模块11,用于在所述用户设备处于RRC空闲态时,通过接收所述基站广播的系统消息块SIB获取所述第一通信资源。
状态转换模块12,用于在所述用户设备处于RRC空闲态时,控制所述用户设备进入RRC连接态。
发送模块13,用于向所述基站发送第一通信资源请求,所述第一通信 资源请求用于请求所述基站分配所述第一通信资源。
所述发送模块13,还用于在所述用户设备处于RRC连接态时,向所述基站发送第一通信资源请求。
