Description

一种通信控制方法、装置及计算机可读存储介质 技术领域
本公开涉及无线通信技术领域，更具体地，涉及一种通信控制方法、装置及计算机可读存储介质。
背景技术
随着通信技术的发展及需求的丰富，无线通信的应用场景也日益广泛，其中比较典型的是车联网(VEHICLE NETWORKING)。所谓的车联网，是车辆可以参与到无线通信中，通过利用先进的无线蜂窝通信技术，实现车与车、车与人、车与路侧基础设施间的实时信息交互，告知彼此目前的状态(包括车辆的位置、速度、加速度、行驶路径)及获知的道路环境信息，协作感知道路危险状况，及时提供多种碰撞预警信息，防止道路交通安全事故的发生。车联网通信的模式具体分为三种：车与车通信(VEHICLE-TO-VEHICLE COMMUNICATIONS，简称V2V)，车与路侧基础设施/网络通信(VEHICLE-TO-INFRASTRUCTURE COMMUNICATIONS，简称V2I/V2N)，车与行人通信(VEHICLE-TO-PEDESTRIAN COMMUNICATIONS，简称V2P)三类，如图1所示，且这三类也可以统称为VEHICLE-TO-EVERYTHING(简称V2X)通信。
相关技术已经支持使用蜂窝无线通信技术来实现车联网应用。在V2V/V2P/V2I车联网通信模式下，车联网信息的传输大多以广播和组播方式为主，现有系统基站支持基于MBSFN(MULTICAST BROADCAST SINGLE FREQUENCY NETWORK，多播组播单频网络)以及SC-PTM(SINGLE CELL POINT TO MULTIPLOINT，单小区点到多点)的广播机制。此外，UE到UE的直接发现/通信(D2D/PROSE/SIDELINK DIRECT DISCOVERY/COMMUNICATION)机制也可以用于支持通过旁链/边链链路进行V2X消息的传输。增强的EV2X通信在延迟、可靠性、数据传输率等方面提出了更高的性能需求，以支持车辆组队、远程驾驶、传感器应用等车联网应用。如EV2X应用场景中数据率在0.5MBPS～1GBPS之间变化。对于通过PC5接口进行的V2X通信，相关技术尚不能满足EV2X场景较高的数据率需求。

具体实施方式
为使本公开的目的、技术方案和优点更加清楚明白，下文中将结合附图对本公开的实施例进行详细说明。需要说明的是，在不冲突的情况下，本申请中的实施例及实施例中的特征可以相互任意组合。
在附图的流程图示出的步骤可以在诸如一组计算机可执行指令的计算机系统中执行。并且，虽然在流程图中示出了逻辑顺序，但是在某些情况下，可以以不同于此处的顺序执行所示出或描述的步骤。
在LTE(Long Term Evolution，长期演进)中，载波聚合(carrier aggregation)机制用于提升数据率及系统容量。配置了载波聚合之后，UE能够同时与多个小区进行数据收发操作。为了提升sidelink(旁链/边链，简称SL)V2X通信的数据传输率，一种解决方法是，为UE配置一个sidelink载频集合，UE同时在多个sidelink载频上进行数据发送/接收，即UE之间使用不同sidelink载频上的sidelink链路进行V2X通信。在这种情况下，一个重要的问题是如何维护与更新UE之间的多个聚合sidelink载频上的sidelink链路。
sidelink载波聚合是一种直接而有效的提升UE在旁链链路上的V2X通信数据率的方法。如图2所示，f1、f2、f3、f4为sidelink载频(该载频上可提供sidelink资源，支持V2X sidelink发现/通信)，UE1驻留在载频f2，同时在载频f1、f4范围内；UE2驻留在载频f3，同时在载频f1、f4范围内；UE3驻留在载频f2，同时在载频f1范围内。UE1和UE2可以通过旁链载波聚合在载频f1、f4上进行V2X sidelink通信；UE1和UE3可以通过旁链载波聚合在载频f2和f1上进行V2X sidelink通信。以UE1和UE3旁链载波聚合V2X sidelink通信为例，假设f1上建立的sidelink链路为主sidelink链路(Sidelink Primary link，简称SL Plink)，通过SL Plink添加的其它载频sidelink链路为辅sidelink链路链路(Sidelink Secondary link，简称SL Slink)。UE1与UE3之间的SL Plink及所有SL Slink为其服务sidelink通信链路(serving sidelink)。在其他实施方式中，UE1与UE3之间的所有旁链载波上的sidelink链路也可以是对等的链路，即f1上的sidelink通信链路与f2上的sidelink链路为平等的2条sidelink链路，称为对等的sidelink链路。
为了更好地管理配置了旁链载波聚合的UE的电池消耗，可以配置通信UE对之间的SL Slink或sidelink链路的激活状态与去激活状态。对于RRC(Radio Resource Control，无线资源控制)连接态的UE，可以由eNB(evoled NodeB，演进的节点B)同时为源UE和目标UE对配置SL Slink或sidelink链路激活/去激活；对于无E-UTRAN(Evolved UMTS Terrestrial Radio Access Network，演进的通用陆地无线接入网)覆盖的UE，可以由UE自主向对端UE发起SL Slink或sidelink链路的激活/去激活(同样适用于RRC连接态UE)。此外，UE的MAC(Media Access Control，媒体接入控制)实体为每个激活的sidelink链路(该sidelink 链路可以是SL Slink或对等的sidelink链路)维护一个去激活定时器，如果在去激活定时器的定时时间内，UE对在该旁链链路上无数据收发，该sidelink链路将去激活。激活状态的sidelink链路，UE可以在对应的载频上进行层1测量(信道质量指示/预编码矩阵索引/轶指示/预编码类型指示/信道状态信息参考信号资源指示、sidelink链路质量测量、SL Slink或对等的sidelink链路上数据传输。去激活状态的sidelink链路，UE仅能在对应的载频上进行sidelink链路质量测量。
对于配置了旁链载波聚合的UE，源UE和目标UE之间的SL Plink及一个或多个SL Slink或多条对等的sidelink链路的信道环境会发生变化，源UE和目标UE需要测量其所有serving sidelink的质量，以及对端UE所支持的除serving sidelink链路所在频点外的其它sidelink频点上进行测量，并根据测量结果决定是否进行sidelink更新。对sidelink测量，可有如下三种方式：对旁链发现信号测量，对旁链同步信号测量，对旁链通信测量。如果某个sidelink链路质量变差，则可以释放该sidelink链路；如果某个其它sidelink频点(非serving sidelink链路所在频点的)上的sidelink链路质量较好，则可以考虑添加到旁链载波聚合的sidelink链路中。如果SL Plink链路质量变差，也可以根据测量结果更换SL Plink。总体上，有两种旁链载波聚合测量配置及SL Plink更换或SL Slink更换/释放或sidelink链路更换/释放的方式：一是基于eNB辅助的SL Plink更换或SL Slink更换/释放或sidelink链路更换/释放，由eNB进行旁链载波聚合测量配置，二是UE之间协商多sidelink链路测量及更新/释放条件。

其余细节请参考前一实施例，此处不再赘述。
以下通过实施例一至实施例四给出实现旁链载波聚合通信UE对之间的旁链链路的激活/去激活的几种方法。
实施例一
UE1与UE2配置了旁链载波聚合，通过SL Plink添加了5条SL Slink，每条SL Slink有对应的link索引SlinkIndex i。SL Plink一直处于激活状态，SL Slink初始为去激活状态。UE1、UE2可以是E-UTRAN覆盖内或E-UTRAN覆盖外。UE1通过用户面方式自主地向对端UE(即UE2)发起SL Slink的激活/去激活。例如，通过SL Plink的sidelink共享信道(SideLink Shared Channel，简称SL-SCH)的激活/去激活MAC控制单元(activation/deactivation MAC CE)指示SL Slink的激活/去激活状态。一种activation/deactivation MAC CE的格式如图5所示，包括S1～S7共7个比特，以及一个预留比特R，其中Si(i＝1～7)指示SlinkIndex i对应的SL Slink的激活/去激活状态，如果某个SlinkIndex i没有配置对应的SL Slink，则忽略对应的Si。在一实施例中，Si设置为1表示激活SlinkIndex i对应的SL Slink，Si为0指示去激活SlinkIndex i对应的SL Slink。当然，此处取值仅为示例。也可以用其他取值指示各SL Slink的激活/去激活状态。
此外，可选的，UE的MAC实体为每个SL Slink维护一个去激活定时器。当SL Slink 上有数据发送或接收时，启动/重启相应的去激活定时器；如果在去激活定时器定时时间内，UE对在该SL Slink上无数据收发，该SL Slink将去激活。其中，去激活定时器的定时时间，UE可以从预配置信息中获得，或从对端UE发送的旁链载波配置信息中获得，或从eNB发送的包含去激活定时器定时时间配置的RRC专有信令中获得。所述去激活定时器的定时时间，为UE specific(UE专有)配置或UE pair specific(UE对专有)配置。所述去激活定时器的定时时间为对应的旁链链路上出现的有旁链资源的子帧数。所述去激活定时器的时间以有旁链资源的子帧为单位进行递减或递增。即，以递减为例，在所述去激活定时器定时开始后，对应的旁链链路上每出现一个有旁链资源的子帧，所述去激活定时器减1，如果出现的是没有旁链资源的子帧，则去激活定时器的值不变，直到去激活定时器超时。所述去激活定时器时间以有旁链资源的子帧为单位进行递减，因为不一定每个子帧上都有旁链资源。例如，去激活定时器定时时间为16，假设在对应旁链载频链路上出现16个有旁链资源的子帧上(这16个子帧不一定是连续的16个上行子帧)没有旁链数据收发，去激活定时器超时。
需要说明的是，UE的MAC实体为每个SL Slink维护一个去激活定时器，可以与任意其它SL Slink激活/去激活方法相结合，以下实例不再特意描述。
SL Slink激活状态下，UE可以对SL Slink进行层1测量、sidelink链路质量测量、SL Slink链路上数据传输；SL Slink去激活状态下，UE可以对SL Slink进行sidelink链路质量测量；其中：
层1测量包括以下至少之一：信道质量指示，预编码矩阵索引，轶指示，预编码类型指示，CSI-RS资源指示；
sidelink链路质量测量包括以下至少之一：sidelink发现信道的RSRP，sidelink发现信道的RSRQ，sidelink通信控制信道的RSRP，sidelink通信控制信道的RSRQ，sidelink通信数据信道的RSRP，sidelink通信数据信道的RSRQ，sidelink同步信道的RSRP，sidelink同步信道的RSRQ，旁链接收信号强度指示。
实施例二
UE1与UE2配置了旁链载波聚合，通过SL Plink添加了5条SL Slink。UE1、UE2可以是E-UTRAN覆盖内或E-UTRAN覆盖外。UE1或UE2通过旁链链路控制信令向对端UE发起SL Slink的激活/去激活。
如图6所示，本实施例提供一种SL Slink激活/去激活方法，包括：
步骤601，UE1发送SL Slink激活状态指示信息给UE2。
其中，UE1通过SL Plink上的控制信令向UE2发送SL Slink激活状态指示信息。所述SL Slink激活状态指示信息包含激活的SL Slink列表和去激活的SL Slink列表其中至少之一，激活/去激活的SL Slink列表中包含激活/去激活的SL Slink索引值或SL Slink所在频点信息。可选的，通过一字节的比特映射(bitmap)指示所配置的所有SL Slink的激活/去激活状态，每一个比特对应一个SL Slink的激活/去激活状态，其余比特填0。
其中，UE1根据要传输的数据量，数据率需求，时延需求，当前激活的sidelink链路资 源负载情况，节电需求，电量指示等sidelink激活/去激活触发因素决定发送所述sidelink激活状态指示信息。
步骤602，所述UE2收到所述UE1发送的SL Slink激活状态指示信息后，根据该SL Slink激活状态指示信息，激活相应的SL Slink或去激活相应的SL Slink。相应地，UE1激活/去激活对应的SL Slink。
步骤603，可选的，所述UE2根据指示信息激活/去激活相应的SL Slink后，发送SL Slink激活状态确认信息给所述UE1。
实施例三
UE1与UE2处于RRC连接态，UE1与UE2配置了旁链载波聚合，由eNB控制SL Slink的激活/去激活。如图7所示，具体包括：
步骤701，eNB配置SL Slink激活状态指示信息给UE1；
在一可选实施例中，eNB通过下行共享信道(Downlink Shared Channel，简称DL-SCH)的MAC PDU(Protocol Data Unit，协议数据单元)中的sidelink激活/去激活MAC控制单元(sidelink activation/deactivation MAC CE)控制UE1与某个目标UE(UE2)之间的SL Slink的激活/去激活状态。
在一实现方式中，sidelink activation/deactivation MAC CE格式如图8所示。UE可能存在一个或多个目标通信UE，因此需要明确该UE与每个目标UE之间的SL Slink的激活/去激活状态。DestinationIndex i(i＝1～N)表示目标UE的标识索引，DestinationIndex i占用4个比特，DestinationIndex i之后紧跟的8个比特S1～S7和预留比特R中，Si(i＝1～7)表示SlinkIndex i对应的UE与DestinationIndex i指示的目标UE之间的SL Slink的激活/去激活状态，如果SlinkIndex i没有配置对应的SL Slink，则忽略其对应的Si。Si设置为1表示激活SlinkIndex i对应的SL Slink，Si为0指示去激活SlinkIndex i对应的SL Slink。图8中还示出了N为偶数和奇数的不同之处。当N为奇数时，DestinationIndex N在S1～S7之后有5个预留比特。需要说明的是，此处sidelink activation/deactivation MAC CE格式仅为示例，可以根据需要使用其他格式携带UE和目标UE的sidelink的激活/去激活状态。
在一实现方式中，eNB配置SL Slink激活状态指示信息给UE1之前，UE1发送sidelink辅助信息给eNB；其中，sidelink辅助信息包括以下至少之一：要传输的数据量，数据率需求，时延需求，当前激活的sidelink链路资源负载情况，节电需求，电量指示。
步骤702，所述UE1收到所述eNB配置的所述UE1与目标UE(本实施例中为UE2)的SL Slink激活状态指示信息后，向目标UE(UE2)发起SL Slink激活状态指示信息；具体地，有用户面(参考实施例一)和控制面(参考实施例二)两种方式，此处不再赘述。
步骤703，UE1、UE2根据SL Slink激活状态指示信息，激活/去激活相应的SL Slink。
步骤704，UE2完成相应的SL Slink激活/去激活后，发送SL Slink激活状态确认信息给UE1。
步骤705：UE1、UE2完成SL Slink激活/去激活后，发送SL Slink激活状态确认信息给 eNB。图7中仅示出了UE1向eNB发送SL Slink激活状态确认信息。需要说明的是，在其他实施例中，也可以只有UE1或UE2其中之一向eNB发送SL Slink激活状态确认信息。
其中，在另一实施例中，步骤704、步骤705也可省略。
此外，需要说明的是，在本公开的一可选实施例中，在步骤701中，eNB可以同时为源UE和目标UE对即UE1、UE2同时配置SL Slink激活状态指示信息(对UE2的配置方法与UE1相同，如步骤701所述)，UE1、UE2根据eNB的配置执行SL Slink激活/去激活，在完成激活/去激活后通知eNB。这样的话，UE1就不需要在sidelink链路向UE2发起SL Slink激活/去激活指示。
实施例四
本实施例描述具有旁链载波聚合能力的UE1、UE2通信对之间多条载波聚合的对等的sidelink链路的激活/去激活方法。
方法一：eNB为UE1、UE2配置sidelink链路的激活/去激活；UE1、UE2处于eNB覆盖内。例如，eNB通过下行共享信道(DL-SCH)的MAC PDU中的sidelink激活/去激活MAC控制单元sidelink activation/deactivation MAC CE控制UE1的某个目标UE(本实施例中为UE2)之间的sidelink链路激活/去激活状态。sidelink activation/deactivation MAC CE格式与图8类似，Si表示SidelinkIndex i对应的sidelink链路的激活/去激活状态，如果SidelinkIndex i没有配置对应的sidelink链路，则忽略Si。Si设置为1表示激活SidelinkIndex i对应的sidelink链路，Si为0指示去激活SidelinkIndex i对应的sidelink链路。
方法二：UE1、UE2通信对之间自主进行sidelink链路的激活/去激活；至少一条或所有sidelink链路初始为激活状态，可以通过任一激活的sidelink链路配置所有sidelink链路的激活/去激活状态。具体地，如实施例一所述，通过sidelink共享信道SL-SCH的激活/去激活MAC控制单元(activation/deactivation MAC CE)指示sidelink链路的激活/去激活状态。activation/deactivation MAC CE格式与图5类似，Si指示SidelinkIndex i对应的sidelink链路的激活/去激活状态，如果SidelinkIndex i没有配置对应的sidelink链路，则忽略Si。Si设置为1表示激活SidelinkIndex i对应的sidelink链路，Si为0指示去激活SidelinkIndex i对应的sidelink链路。或者，如实施例2所述，UE1或UE2通过任一激活的旁链链路的控制信令向对端UE发起sidelink链路的激活/去激活。
方法三：eNB为UE1配置sidelink链路的激活/去激活，UE1向对端UE2发起sidelink链路的激活/去激活，至少一条sidelink链路初始为激活状态，可以通过任一激活的sidelink链路配置其它sidelink链路的激活/去激活状态。
方法四：UE为每个激活的sidelink链路维护一个去激活定时器。当sidelink链路上有数据发送或接收时，启动/重启相应的去激活定时器；如果在去激活定时器的定时时间内，UE对在该sidelink链路上无数据收发，该sidelink链路将去激活。其中，UE可以通过以下方式获取去激活定时器的定时时间：从预配置信息中获得，或从对端UE发送的旁链载波配置信息中获得，或从eNB发送的包含去激活定时器定时时间配置的RRC专有信令中获得。去激 活定时器的定时时间，为UE specific配置或UE pair specific配置。该方法可以与方法一至三中任意一种相结合。
