Description

无线通信中的电子设备和方法
本申请要求于2016年8月10日提交中国专利局、申请号为201610653477.9、发明名称为“无线通信中的电子设备和方法”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本公开涉及无线通信领域，具体地涉及车辆通信(V2X)领域。更具体地，涉及一种快速确定V2X通信中的下行组播/广播区域的方案。
背景技术
在基于Uu接口的V2X通信中，发送车辆(Transmission Vehicular UE，T-VUE)产生的数据信息(在下文中也可称为V2X消息)经上行信道发送给其服务基站，服务基站接收到该消息后，经下行信道将该消息组播/广播到该T-VUE周围一定距离的影响区域内。然而，由于该T-VUE周围一定范围内的接收车辆(Receiving Vehicular UEs，R-VUEs)可能位于不同的小区内，因此为了保证所有R-VUEs能够正确接收到该消息，可能需要在多个小区内组播/广播该消息。
在现有相关技术中，通常由基站维护相应的R-VUEs组并根据R-VUEs所在位置确定组播/广播区域。然而，这种方案需要基站动态更新所有VUE的位置信息，因此信令开销较大，并且在位置信息不可用的情况下，无法确定此时的组播/广播区域。因此，期望一种能够快速高效地传播V2X消息的解决方案，其能够实现以下优点中的一个或多个：信令开销减小、时延缩短以及V2X消息的有效传递。

具体实施方式
在下文中将结合附图对本公开的示范性实施例进行描述。为了清楚和简明起见，在说明书中并未描述实际实施方式的所有特征。然而，应该了解，在开发任何这种实际实施例的过程中必须做出很多特定于实施方式的决定，以便实现开发人员的具体目标，例如，符合与系统及业务相关的那些限制条件，并且这些限制条件可能会随着实施方式的不同而有所改变。此外，还应该了解，虽然开发工作有可能是非常复杂和费时的，但对得益于本公开内容的本领域技术 人员来说，这种开发工作仅仅是例行的任务。
在此，还需要说明的一点是，为了避免因不必要的细节而模糊了本公开，在附图中仅仅示出了与根据本公开的方案密切相关的设备结构和/或处理步骤，而省略了与本公开关系不大的其它细节。
在具体描述本公开的实施例之前，应指出，尽管在本公开的实施例中以车辆通信(V2X)应用场景为例来描述本公开的技术，但是本公开的技术显然不限于该应用场景，而是可类似地应用于通信设备的位置动态变化的任何通信场景，并且用户设备的示例显然也不限于车载终端(例如，车载导航设备)，而是可以包括任何移动终端(例如，智能手机、平板电脑、个人数字助理(PDA)等)。V2X通信可例如包括车辆到车辆(V2V)通信、车辆到基础设施(V2I)通信、车辆到行人(V2P)通信等。
接下来，将参照图1至图21详细描述本公开的实施例。
图1是示出在V2X通信的不同场景下的下行组播/广播区域的变化的示意图。如图1所示，在场景A中，T-VUE位于其服务小区的中央区域，受其V2X消息影响的R-VUEs都位于该小区内，因此组播/广播只需在此小区内进行；在场景B中，T-VUE位于两个相邻小区的边界区域，受其影响的R-VUEs位于这两个相邻小区内，因此组播/广播需要在这两个相邻小区内进行；而在场景C中，T-VUE位于三个相邻小区的边界区域，受其影响的VUE位于该三个相邻小区内，因此组播/广播需要在这三个相邻小区内进行。
可以理解，在V2X通信中，车辆的快速移动将导致T-VUE和R-VUEs的位置以及R-VUEs成员的快速变化，从而进一步导致组播/广播范围的动态变化和V2X消息影响范围内的接收车辆的动态变化，因此，迫切需要一种能够高效地确定组播/广播区域的解决方案。
第一实施例
首先，将参照图2描述根据本公开的第一实施例的无线通信中的用户设备端的电子设备的功能配置示例。图2是示出根据本公开的第一实施例的无线通信中的用户设备端的电子设备的功能配置示例的框图。
如图2所示，根据该实施例的用户设备端的电子设备200可包括测量单元 202和确定单元204。
测量单元202可被配置成测量用户设备的服务基站和邻近基站的下行信道质量。该测量事件可以是响应于预定触发事件而执行的，或者也可以是预定周期而周期性地执行的，本公开对此不做限制。预定触发事件可以包括但不限于V2X消息发送请求。
下行信道质量的测量结果可以包括信道质量指示(CQI)、参考信号接收功率(RSRP)、参考信号接收质量(RSRQ)、接收信号强度指示(RSSI)以及参考信号信干噪比(RS-SINR)中的一个或多个。在以下描述中，以RSRP为例来描述本公开的技术的具体实现，但是显然本公开的技术也可以替代地使用CQI、RSRQ、RSSI或RS-SINR或者它们的组合来实现。
具体地，例如，测量单元202可以根据来自其服务基站(eNB)的测量配置信息而测量其服务基站和邻近基站的RSRP。该测量配置信息可以由服务基站通过例如无线资源控制连接重配置(RRCConnectionReconfiguration)消息携带的measConfig信元将测量配置信息通知给用户设备，该测量配置信息可包括测量对象、基站列表、报告方式、测量标识、事件参数等中的一个或多个。在该应用示例中，测量对象为RSRP，基站列表为服务基站和邻近基站，报告方式为周期性上报，测量方式为连续测量。
确定单元204可被配置成基于所测量的下行信道质量而从服务基站和邻近基站中确定第一基站集合，第一基站集合表示要对来自用户设备的数据信息进行广播或组播的基站集合。
具体地，下行信道质量测量结果(诸如变化趋势、幅值等信息)可用来反映用户设备(例如，发送车辆)的移动轨迹以及相对于周围基站的位置。例如，如果在一定测量时间内(例如，数据信息的生命周期内)对于某一基站的下行信道质量的测量结果的变化趋势为增大并且平均测量值或者测量结束时的最终值的幅值较大，则说明发送车辆正在移动靠近该基站并且距该基站的距离较近，从而该基站的小区覆盖范围内的用户设备会受到该数据信息的影响，应该将该基站加入到第一基站集合中，以将发送用户设备的数据信息组播/广播到其小区覆盖范围内的用户设备。
具体地，确定单元204可被配置成基于所测量的下行信道质量的变化趋势 及幅值而确定第一基站集合。
优选地，作为一种示例实现方式，确定单元204可基于变化趋势为增大的、幅值排序靠前的第一预定数量的下行信道质量之间的差值关系和数据信息的影响范围来确定第一基站集合。
具体地，假设确定单元204选择变化趋势为增大的下行信道质量(这里例如为RSRP)并且将这些下行信道质量按均值(或者按测量结束时的终值)从大到小排序，并且取前K(这里，假设K等于例如3)个RSRP，分别表示为RSRP1、RSRP2、RSRP3，并且分别对应于基站eNB1、eNB2、eNB3。然后，确定单元204可以例如根据以下差值关系，确定相应的第一基站集合：
(a)如果RSRP1-RSRP2>T1并且RSRP1-RSRP3>T1，则可以确定第一基站集合仅包括基站eNB1；
(b)如果RSRP1-RSRP2<T2并且RSRP1-RSRP3>T1，则可以确定第一基站集合包括基站eNB1和eNB2；以及
(c)如果RSRP1-RSRP2<T2并且RSRP1-RSRP3<T2，则可以确定第一基站集合包括基站eNB1、eNB2和eNB3。
T1和T2分别表示预定阈值，并且满足T1>T2。下面将参照图3详细描述确定T1和T2的一种示例方式。图3是示出根据本公开的实施例的确定第一基站集合的第一示例方式的示意图。
在图3所示的示例中，假设数据信息(例如为V2X消息(message))的影响范围为dm，在T-VUE处接收eNB1的功率为RSRP1，接收eNB2的功率为RSRP2，功率差为RSRP1-RSRP2。从T-VUE到eNB1的距离为d1，从T-VUE到eNB2的距离为d2，并且基站eNB1和eNB2之间的距离为D。在该情况下，T1可以取保证所有接收车辆R-VUE刚好位于eNB1的覆盖范围内时的功率差的最大值，如图3中的(a)所示，并且T2可以取保证所有接收车辆R-VUE刚好位于eNB1的覆盖范围内时的功率差的最小值，如图3中的(b)所示。通过根据上述计算条件进行计算、化简，可以发现，T1和T2的取值与V2X消息的影响范围dm有关。
V2X消息的影响范围dm用于反映希望R-UE接收该消息的覆盖范围。一般地，V2X消息的影响范围dm可以与V2X消息的类别和用户设备的移动速 度至少之一有关。示例性地，V2X消息的类别可通过消息的重要程度或影响程度或消息发生的地点来区分。在某一示例中，该类别可通过消息的优先级来区分。例如，对于包含重大交通事故的V2X消息(优先级高)，该V2X消息的影响范围dm可以较大。在另一示例中，根据发出消息时车辆所在地点来区分消息的类别。例如，对于在城市范围行驶时发出的V2X消息，其影响范围可以是例如150米，而对于在高速公路行驶时发出的V2X消息，其影响范围可以是例如320米。此外，在另一示例中，车辆行驶速度越大，为了保证接收车辆的反应时间，影响范围dm应该越大。
对于影响范围dm的控制，可通过多种方式来实现。例如，如果消息的影响范围在用户设备的发射能力范围之内，则用户设备可以通过功率控制来形成不同的影响范围。例如，发送车辆可以根据当前行驶速度、要发送的消息的类别等而调整其发射功率，从而形成该消息的影响范围。影响范围内的车辆如果接收到该消息，则可以根据所接收到的消息(例如，道路安全消息等)而做出相应反应(例如，调整自身的行驶速度、行驶路线等)，另外，也可通过控制接收车辆对V2X消息选择性地解析来控制影响范围dm。例如，影响范围之内的车辆接收并解析V2X消息，而对于影响范围之外的车辆，由于该消息可能对这些车辆并没有太大影响，因此这些车辆即使接收到该消息也无需解析或做出反应。
应指出，尽管以上给出了上述三种差值关系来确定第一基站集合的示例，但是显然差值关系并不仅限于以上三种，而是可以考虑更多种差值关系(例如，RSRP2与RSRP3的差值关系)。某一实施例中，为了减轻计算负荷，可以仅需要考虑所选取的下行信道质量的测量值与其中的最大值之间的差值关系即可确定第一基站集合。
另一方面，在上述三种差值关系都不满足的情况下，确定单元204可进一步被配置成还基于上述确定的第一预定数量的下行信道质量对应的基站之间的距离来确定第一基站集合。具体地，例如，可以采用以下参照图4描述的方式来确定第一基站集合。图4是示出根据本公开的实施例的确定第一基站集合的第二示例方式的示意图。
在图4所示的示例中，假设发送车辆T-VUE的发送功率为P，并且在 T-VUE处接收到eNB1、eNB2、eNB3的功率分别为RSRP1、RSRP2、RSRP3，则可以确定T-VUE距eNB1、eNB2、eNB3的距离d1、d2和d3分别为：
Figure PCTCN2017093805-appb-000001
Figure PCTCN2017093805-appb-000002
Figure PCTCN2017093805-appb-000003
然后，如图4所示，根据d1、d2、d3以及各个基站间的距离D，利用三角测量方法确定T-VUE的相对位置，并且进一步根据V2X消息的影响范围dm得到以T-VUE为圆心、半径为dm的圆，并且根据该圆的覆盖范围来确定第一基站集合。
应指出，尽管以上描述了在判断差值关系不满足的情况下才利用图4所示的方式来确定T-VUE的位置进而确定第一基站集合，但是，这仅是示例而非限制。实际上，图4所示的确定方式具有更普遍的适用性，即，也可在无需判断差值关系的情况下，直接利用图4所示的方式来确定第一基站集合。然而，为了减轻计算负荷，优选地，可以如上所述先利用差值关系来确定第一基站集合，如果利用差值关系无法确定，再利用图4所示的三角测量方法来确定第一基站集合，这样既能尽可能地减轻计算负荷，又可有效地确定第一基站集合。
优选地，电子设备200还可包括生成单元，该生成单元可被配置成生成包括数据信息和第一基站集合的报告以发送至其服务基站。从而，服务基站可以根据所接收到的报告而将数据信息发送至第一基站集合中的各个基站，以由这些基站对所接收到的数据信息进行组播/广播。
可以看出，根据以上描述的根据下行信道质量测量来确定组播/广播区域的方案，即使在用户设备的位置信息不可用的情况下，例如，在车辆处于隧道或地下停车场等场所中从而GPS信号被遮挡的情况下，也可以快速地确定组播/广播基站集合。
此外，对于V2X通信，由于发送车辆和接收车辆均处于运动中，因此组播/广播区域也是动态变化的。例如，如图1所示，假设发送车辆从场景A移 动至场景B然后移动至场景C，从而组播/广播区域也相应地变化。因此，如果在确定了第一基站集合之后再在基站间传输V2X消息，可能会造成不必要的延时。
为了解决该问题，优选地，可以考虑将V2X消息预先缓存在发送车辆的行进路线上的一些基站内，从而当这些基站落入组播/广播区域内时，可以立即对所缓存的V2X消息进行组播/广播。这样，能够大大减少不必要的延时，提高了V2X消息的实时性。
优选地，确定单元204可进一步被配置成基于所测量的下行信道质量而从服务基站和邻近基站中确定第二基站集合，第二基站集合表示要预先缓存数据信息的基站集合。
作为一种示例实现方式，确定单元204可根据测量单元202的测量结果，将下行信道质量的变化趋势为增大的、幅值排序靠前的第二预定数量的基站确定为第二基站集合。
可以理解，如上所述，对于下行信道质量的变化趋势为增大且幅值较大的基站，说明用户设备(即，发送车辆)正在移动靠近这些基站，也就是说，这些基站位于发送车辆的行进路线上，从而可以由用户设备的服务基站通过例如X2接口将数据信息提前发送至这些基站进行缓存，这样，一旦发送车辆行进至相应位置使得这些缓存基站落入组播/广播区域内，这些基站可以立即对所缓存的数据信息进行组播/广播。
具体地，例如，确定单元204可以在测量结束时选取不断增大的RSRP并且将这些RSRP按其均值(或者测量结束时的终值)从大到小排序，取前N个RSRP，例如，N＝4，从而RSRP1、RSRP2、RSRP3、RSRP4对应的基站eNB1、eNB2、eNB3、eNB4被确定为第二基站集合。图5示出了根据本公开的实施例的第二基站集合的示例的示意图。
应指出，通常，N≥K，即，第一基站集合(即，组播/广播基站集合)是第二基站集合(即，缓存基站集合)的子集。换言之，缓存基站集合通常包括更宽范围的基站，而组播/广播基站集合仅考虑了在当前位置需要进行组播/广播的基站。
优选地，上述生成单元所生成的报告还包括关于第二基站集合的信息。一 般来说，用户设备的服务基站包括在所确定的第二基站集合中，从而服务基站可以根据所接收到的报告，通过例如X2接口将数据信息提前发送至第二基站集合中的各个基站进行缓存。
作为一种优选方式，由于生成单元所生成的报告包括第一基站集合和第二基站集合，并且第一基站集合通常是第二基站集合的子集，因此，关于基站集合的报告格式可以简化为如下表1所示。
表1基站集合的报告格式
CellID1+(1/0) CellID2+(1/0) CellID3+(1/0) ... CellIDN+(1/0)
可以看出，所生成的报告包括所确定的N个缓存基站的小区标识(cellID)以及一位标识位，其中，“1”表示该基站属于第一基站集合(组播/广播基站集合)，“0”表示该基站属于第二基站集合(缓存基站集合)。
这样，当某一基站从缓存基站变为组播/广播基站时，服务基站仅需向该基站发送一比特的标识“1”，从而触发接收到该标识的基站对数据信息进行组播/广播。这样，可以减少基站间的信令开销。
应指出，尽管以上给出了用于确定第一基站集合和第二基站集合的示例实现方式，但是这仅是示例而非限制，本领域技术人员可以根据本公开的原理，即，下行信道质量测量结果反映了用户设备与基站间的相对位置、用户设备的行进路线等信息，从而可以根据下行信道质量测量结果而确定相应的组播/广播区域以及缓存区域，对上述示例进行修改。例如，K和N的取值不特别限制，而是可以根据实际情况来选择。又例如，下行信道质量测量结果不一定是RSRP，而是可以是CQI、RSRQ、RSSI或RS-SINR等。又例如，可以不基于差值关系而是直接利用三角测量方法来确定组播/广播区域。
此外，考虑如下场景：并不是组播/广播基站的覆盖范围内的所有用户设备都需要接收来自发送用户设备的数据信息，一般来说，仅在发送用户设备周围一定范围内的用户设备才需要接收这些数据信息。因此，期望能够避免用户设备的不必要接收以便降低功耗。
在现有技术中，通常存在两种广播方式，即，多播/组播单频网络(MBSFN)方式和单小区点到多点(SC-PTM)方式。对于MBSFN方式，由于不能与物 理下行共享信道(PDSCH)或者同步信令复用，并且每个帧里只有六个子帧分配给MBSFN，因此限制了MBSFN的容量。MBSFN具有广播普遍存在的问题，即，存在不必要的接收。例如，当发送车辆离开了V2V传输范围后，MBSFN范围内的车辆还要检测所有数据包，从而增大了功耗。对于SC-PTM方式，其组播给特定的用户设备，并且在组播前eNB会给相应的用户设备分配临时移动组标识(TMGI)，从而在一定程度上避免了不必要的接收。但是，对于V2X通信场景，由于车辆的快速移动及变化，所有车辆需要频繁上报地理位置信息，这样eNB才能确定给哪些车辆分配相同的TMGI，并且在地理位置信息不可用的情况下，则无法实时地为车辆分配适当的TMGI。因此，现有的SC-PTM方式的信令开销较大并且具有一定的应用局限性。
鉴于上述问题，期望提供一种能够避免用户设备的不必要接收同时保证数据传输性能以及减少信令开销的方案。
在V2X通信中，V2X消息可以区分为高优先级消息和低优先级消息。由于MBSFN的专用资源有限且不需要给用户分配组标识，时延较短且覆盖范围广，因此高优先级消息可以优先使用MBSFN方式。SC-PTM方式使用PDSCH资源并需要给用户分配组标识，因此低优先级消息可使用SC-PTM方式。用户设备可以在向服务基站发送调度请求(SR)以请求分配上行通信资源时将此时发送的数据信息的优先级报告给服务基站。
然而，如上所述，如果直接将现有的SC-PTM方式应用于V2X通信场景，则可能导致信令开销较大。因此，本公开针对通信设备的位置动态变化的通信场景(例如V2X通信场景)提出了一种改进的SC-PTM方式。
以V2X通信场景为例，由于受V2X消息影响的车辆一般位于发送车辆周围一定距离内，因此考虑由发送车辆广播一个组标识符(例如，RNTI)，只有能够正确接收到该组标识符的周围车辆才需要接收该V2X消息并且对由该组标识符加扰的V2X消息进行解码。该组标识符可以是服务基站响应于用户设备发送的指示V2X消息的优先级的优先级指示而分配的。
另外，由于发送车辆周围可能不断地有新的车辆加入或者驶出，为了保证新加入的车辆能够正确对V2X消息进行解码，发送车辆可以周期性地广播该组标识符。
根据以上实施例，可以在避免不必要的接收的同时，保证高优先级数据信息的接收性能，并且减少信令开销。
可以看出，在V2X通信中，优选地，上述电子设备200不仅支持蜂窝通信(cellular communication)以便与基站进行通信，还支持设备到设备(D2D)通信以便与其他车辆设备直接通信。
作为一种优选实现方式，电子设备200还可包括支持蜂窝通信的第一接口(例如Uu接口)以及支持D2D通信的第二接口(例如PC5接口)。例如，电子设备200可以经由第一接口向服务基站发送指示数据信息的优先级的优先级指示并接收服务基站基于该优先级指示而发送的组标识符，然后经由第二接口周期性地广播该组标识符。
可以理解，上述电子设备200可以以芯片级来实现，或者也可通过包括其它外部部件而以设备级来实现。例如，电子设备200可以作为整机而工作为用户设备，从而可包括上述第一接口和第二接口以进行蜂窝通信和设备间通信。此外，还应理解，第一接口和第二接口仅是根据其功能而做出的逻辑划分，在实际实现时，这两个接口也可以合并为一个接口，该接口能够同时支持蜂窝通信和设备间通信。
与以上描述的用户设备端的电子设备相对应的，下面将参照图6描述根据本公开的实施例的基站端的电子设备。图6是示出根据本公开的第一实施例的无线通信中的基站端的电子设备的功能配置示例的框图。
如图6所示，根据该实施例的电子设备600可包括确定单元602和通信接口604。
确定单元602可被配置成根据来自基站服务的用户设备的报告而确定数据信息和第一基站集合。第一基站集合可以是如上所述由用户设备根据服务基站和周围基站的下行信道质量测量结果而确定的，并且表示要对用户设备的数据信息进行组播/广播的基站集合。
通信接口604可被配置成执行收发操作。具体地，电子设备600可经由通信接口604从用户设备接收包括数据信息和第一基站集合的报告，并且根据确定单元602的确定结果而经由通信接口604将数据信息发送至第一基站集合中的各个基站。应指出，该通信接口604是可选的(在图6中以虚线框示出)， 例如，在电子设备600以芯片级实现的情况下，其可不包括收发功能而不需要包括通信接口604。
优选地，如上所述，来自用户设备的报告还可包括第二基站集合，从而确定单元602可进一步被配置成根据所接收的报告而确定第二基站集合，以经由通信接口604将数据信息发送至第二基站集合中的各个基站进行缓存。该第二基站集合可以是如上所述由用户设备根据对周围基站的下行信道质量测量结果而确定的。
具体的确定第一基站集合和第二基站集合的过程可参见以上描述，在此不再重复。
优选地，确定单元602可进一步被配置成根据所接收的报告而确定指示特定基站属于第一基站集合还是第二基站集合的标识，以便将该标识与数据信息一起发送至该基站。如上所述，用户设备在将所确定的基站集合报告给服务基站时，除了各个基站的标识符(ID)之外，报告中还包括指示该基站属于第一基站集合还是第二基站集合的标识，例如，标识“1”表示该基站属于第一基站集合，标识“0”表示该基站属于第二基站集合，从而基站端的电子设备600可根据所确定的标识，将数据信息和标识“1”发送至属于第一基站集合的基站，以指示该基站在接收到数据信息之后进行组播/广播，并且将数据信息和标识“0”发送至属于第二基站集合的基站，以指示该基站仅缓存所接收到的数据信息而不进行组播/广播。
此外，优选地，随着用户设备的移动，当确定单元602根据所接收的报告确定原来属于第二基站集合的基站变为属于第一基站集合的基站时，其可生成指示该基站属于第一基站集合的标识以发送至该基站。具体地，例如，此时，电子设备600可将所生成的标识“1”发送至相应基站，以触发该基站对缓存的数据信息进行组播/广播。
这里，应指出，尽管以上描述了由用户设备端来确定第一基站集合和第二基站集合的示例实现方案，但是替选地，这些确定操作也可以由基站端来执行，即，用户设备将所获得的下行信道质量测量结果报告给其服务基站，从而由基站根据上述方式来确定第一基站集合和第二基站集合。在该情况下，用户设备仅需将数据信息发送给服务基站，服务基站会根据自己所确定的基站集合而将 数据信息和相应的标识分别发送至相应的基站。
此外，优选地，为了避免不必要的接收，确定单元602还可根据从用户设备接收到的指示数据信息的优先级的优先级指示，确定用户设备的组标识符，以通过通信接口604发送至用户设备。具体地，如果确定数据信息属于低优先级信息，则可以为用户设备分配相应的组标识符，从而用户设备可对该组标识符进行广播，使得仅能够接收到该组标识符的用户设备才能够接收和解码利用组标识符加扰的数据信息。
作为一种示例实现方式，可由电子设备600利用组标识符对所接收的数据信息进行加扰，并且将加扰后的数据信息发送至第一基站集合和第二基站集合中的各个基站。替选地，作为另一种示例实现方式，电子设备600也可将组标识符和数据信息一起发送至第一基站集合和第二基站集合中的各个基站而不进行加扰，当需要进行组播/广播时，由相应基站利用组标识符对数据信息进行加扰并进行组播/广播。
可以理解，类似地，上述电子设备600可以以芯片级来实现，或者也可通过包括其它外部部件而以设备级来实现。例如，当以芯片级来实现时，电子设备600可不包括上述通信接口604；而当以设备级来实现时，可以作为整机而工作为基站。
此外，应理解，上述电子设备200和电子设备600中的各个单元仅是根据其所实现的具体功能划分的逻辑功能模块，而不是用于限制具体的实现方式。在实际实现时，上述各个功能单元可被实现为独立的物理实体，或者也可由单个实体(例如，处理器(CPU或DSP等)、集成电路等)来实现。
为了进一步便于理解上述实施例中的技术方案，下面将参照图7A和图7B来简要描述用于实现基于下行信道质量测量的下行组播/广播区域确定方案的示例流程。
图7A是示出根据本公开的实施例的基于下行信道质量测量的下行组播/广播区域确定方案的示例的交互流程图。
首先，如图7A所示，响应于预定触发事件或者根据预定周期，用户设备(这里例如为发送车辆T-VUE)开始测量周围基站的下行信道质量。然后，在步骤S701中，发送车辆T-VUE在相应资源上向服务基站(eNB)发送调度 请求(SR)以请求分配上行传输资源。随后，在步骤S702中，服务基站eNB通过上行授权(UL grant)信令为T-VUE分配上行资源。然后，在测量结束时，在步骤S703中，发送车辆T-VUE将数据信息以及根据所测量的下行信道质量而确定的基站集合(包括第一基站集合和第二基站集合)在所分配的上行资源上报告给服务基站。基站集合的报告格式例如可以如上述表1所示。
替选地，如上所述，第一基站集合和第二基站集合的确定也可由基站端来执行。下面将参照图7B描述该情况下的交互流程图。
图7B是示出根据本公开的实施例的基于下行信道质量测量的下行组播/广播区域确定方案的另一示例的交互流程图。
图7B所示的交互流程图与图7A所示的交互流程图基本上相同，区别仅在于，在步骤S703’中，取代将所确定的基站集合报告给服务基站，用户设备将数据信息和下行信道质量测量结果(例如，RSRP)报告给服务基站，以由服务基站根据测量结果、利用相应算法来确定第一基站集合和/或第二基站集合。
应指出，图7A和图7B所示的交互流程图仅是示例而非限制，本领域技术人员也可以根据以上详细描述以及本公开的原理而对上述交互流程图进行修改，例如，可以在发送SR时同时向服务基站发送指示数据信息的优先级的优先级指示。又例如，在向服务基站发送数据信息和下行信道质量测量结果时，还需要向服务基站发送数据信息的影响范围等信息，以供基站确定第一基站集合和第二基站等。所有这样的修改显然应落入本公开的范围内，在此不再一一列举。
第二实施例
以上描述了基于下行信道质量测量来确定组播/广播区域的方案，下面将参照图8至图11来描述基于地理位置预测来确定组播/广播区域的方案。
图8是示出根据本公开的第二实施例的无线通信中的基站端的电子设备的功能配置示例的框图。
如图8所示，根据该实施例的电子设备800可包括子区域集合确定单元802和基站集合确定单元804。
子区域集合确定单元802可被配置成根据用户设备的移动位置和来自用户设备的数据信息的影响范围而确定第一子区域集合。
这里的子区域(zone)是通过对小区覆盖范围进行划分而得到的，通常可在网络端预先配置好，并且服务基站事先已掌握了本小区和邻近小区内的子区域的划分。
作为示例，子区域的划分可以包括但不限于以下几种方式：基于地理位置坐标(例如，经纬度)在全网统一划分，从而每个子区域在全网具有唯一的子区域标识符(ZoneID_Global)；在单个小区内根据实际情况而独立划分，例如，对于小小区，子区域划分的粒度可以小一些从而划分得到的子区域较密集，而对于宏小区，子区域划分的粒度可以大一些从而划分得到的子区域较稀疏，在该情况下，每个子区域可以利用小区标识符和在该小区内的子区域标识符(CellID+ZoneID_Local)来唯一地标识；以及在相邻的两个或更多个小区构成的小区组内进行划分，在该情况下，每个子区域可以利用小区组标识符和在该组内的子区域标识符(CellSetID+ZoneID_Local)来唯一地标识。
可以看出，子区域(zone)与小区(cell)之间没有必然的联系，只是从划分粒度上来说，子区域的粒度一般粗于具体的地理位置信息的粒度而细于小区的粒度。此外，子区域的划分当然也不限于以上列出的方式，本领域技术人员可以根据实际需要而进行适当的子区域划分，并且具体的划分粒度也可根据实际场景来确定，本公开对此不做具体限制。图9示出了根据本公开的实施例的子区域划分的示例的示意图。如图9所示，其中的每个格子可以表示一个子区域(zone)。
作为一种示例实现方式，在地理位置信息可用的情况下，子区域集合确定单元802可被配置成根据用户设备报告的当前位置信息和移动速度而估计用户设备的移动位置，从而基于例如预先存储的位置信息与子区域之间的对应关系(例如，查找表的形式)而确定该移动位置所属的子区域。
具体地，如图9所示，电子设备800在接收到上报信息之后，根据用户设备的当前位置C和移动速度V而估计在经过了时间间隔▽t之后用户设备的移动位置C’，并确定该移动位置所属的子区域。其中，时间间隔▽t表示服务基站收到上报信息的时刻到相应广播资源之间的时间间隔。该确定过程可以表示 为：
C’＝C+V×▽t
C’→ZoneID
替选地，作为另一实例实现方式，如果位置信息不可用，还可基于用户设备对周围基站的下行信道质量的测量结果来估计用户设备的移动位置。即，子区域集合确定单元802可进一步被配置成根据用户设备报告的对于基站和邻近基站的下行信道质量测量结果，估计用户设备的移动位置，进而基于预先存储的对应关系而确定该移动位置所属的子区域。
具体地，如以上参照图4所描述的方式，子区域集合确定单元802可利用三角测量方法、根据下行信道质量测量结果和基站间的距离来估计用户设备的移动位置，该下行信道质量测量结果至少包括下行信道质量的变化趋势及幅值。具体的实现过程与以上参照图4描述的确定用户设备的相对位置时的过程基本上相同，区别仅在于，在以上描述中，由用户设备来估计其所处的位置，而在该实施例中，用户设备需要将测量结果报告给服务基站由基站来估计用户设备的移动位置，在此不再重复描述该过程。
可以理解，在基于下行信道质量测量结果来估计用户设备的移动位置的上述方案中，由于选取了变化趋势为增大的下行信道质量测量结果，因此与以上基于地理位置信息的方案类似，这里所估计的移动位置也是用户设备的移动轨迹上的预测位置。
在如上所述确定了用户设备所处的子区域之后，子区域集合确定单元802可根据所确定的用户设备所处的子区域，并且结合用户设备所报告的数据信息的影响范围dm来确定受数据信息影响的第一子区域集合，即，ZoneID+dm→Zone Set。
然后，基站集合确定单元804可被配置成根据所确定的第一子区域集合中的各个子区域所属的小区，确定第一基站集合，从而服务基站可将来自用户设备的数据信息发送至第一基站集合中的各个基站以进行组播/广播，即，Zone Set→eNB Set。
可以理解，在上述技术方案中，取代基于具体的地理位置信息的变化而基于子区域的变化来确定第一基站集合的变化，由于子区域的划分粒度介于小区 与具体地理位置之间，因此，在该方案中，虽然用户设备仍然会周期性地上报地理位置信息或信道质量测量信息，但是如果所估计的用户设备所处的子区域不变，那么受数据信息影响的子区域集合就不变，从而要进行组播/广播的基站集合也不变。这样，对于例如车辆的位置频繁变化的V2X通信场景，可以大大减轻处理负荷以及降低信令开销。
类似地，如上所述，作为缓存基站集合的第二基站集合的确定也可以由服务基站端来执行。优选地，基站集合确定单元804可进一步被配置成根据用户设备报告的对于服务基站和邻近基站的下行信道质量测量结果，确定第二基站集合，从而服务基站可以将数据信息提前发送至第二基站集合中的各个基站进行缓存。
具体地，基站确定单元804可将下行信道质量测量结果的变化趋势为增大的、幅值排序靠前的预定数量的基站确定为第二基站集合。具体的确定第二基站集合的方式与以上用户设备端所执行的确定方式相同，在此不再重复描述。
可以理解，上述电子设备800可以以芯片级来实现，或者也可通过包括其它外部部件而以设备级来实现。例如，电子设备800还可以包括通信接口以作为整机而工作为基站，该通信接口可被配置成执行收发操作，例如，与用户设备以及与其它基站进行收发操作。
这里，应指出，这里的电子设备800同样可以如上述电子设备600一样执行用于避免不必要接收的操作，具体可参见以上相应位置的描述，在此不再重复。
与基站端的电子设备800相对应地，接下来将参照图10描述用户设备端的电子设备的功能配置示例。图10是示出根据本公开的第二实施例的无线通信中的用户设备端的电子设备的功能配置示例的框图。
如图10所示，根据该实施例的电子设备1000可包括生成单元1002和通信接口1004。
生成单元1002可被配置成生成至少包括用户设备的数据信息的影响范围的报告。
然后，电子设备1000经由通信接口1004将所生成的报告发送至服务基站，从而服务基站可根据用户设备的移动位置所属的子区域和数据信息的影响范 围而确定第一子区域集合，进而基于第一子区域集合确定第一基站集合，以便将来自用户设备的数据信息发送至第一基站集合中的各个基站进行组播/广播。
通信接口1004可被配置成支持蜂窝通信和设备间通信。可以理解，通信接口1004是可选的(在图10中以虚线框示出)，例如，在电子设备1000以芯片级来实现的情况下，其可不包括收发功能而不需要包括通信接口1004。
优选地，所生成的报告还可包括用户设备的当前位置信息和移动速度，以供服务基站估计用户设备的移动位置。
此外，优选地，所生成的报告还可包括用户设备对服务基站和周围基站的下行信道质量测量结果，以供服务基站估计用户设备的移动位置以及确定要预先缓存数据信息的第二基站集合。
应指出，移动位置的确定也可以在用户设备端执行。具体地，用户设备可以根据下行信道质量测量结果来估计其移动位置，然后将该移动位置发送给服务基站，从而服务基站可以根据该位置以及所掌握的子区域划分等信息而确定相应的子区域集合进而确定第一基站集合。同样地，第二基站集合的确定也可以在用户设备端执行。
应理解，电子设备1000可以以芯片级或设备级来实现。当以芯片级实现时，电子设备1000可不包括上述通信接口1004；而当以设备级来实现时，可以作为整机而工作为用户设备。
此外，应指出，上述电子设备800和电子设备1000中的各个单元仅是根据其所实现的具体功能划分的逻辑功能模块，而不是用于限制具体的实现方式。在实际实现时，上述各个功能单元可被实现为独立的物理实体，或者也可由单个实体(例如，处理器(CPU或DSP等)、集成电路等)来实现。
为了进一步有利于理解本实施例的方案，下面将参照图11描述基于地理位置预测的方案的示例的交互流程。图11是示出根据本公开的实施例的基于地理位置预测的下行组播/广播区域确定方案的交互流程图。
如图11所示，首先，在步骤S1101中，响应于预定触发事件或者根据预定周期，用户设备(这里例如为发送车辆)在相应的资源上发送调度请求SR。然后，在步骤S1102中，服务基站eNB通过UL grant为用户设备分配上行资 源。接下来，在步骤S1103中，用户设备在所分配的上行资源上向服务基站上报信息。所上报的信息可以包括数据信息本身以及数据信息的影响范围dm，并且还可以可选地包括用户设备的当前地理位置、移动速度、对于周围基站的下行信道质量测量结果等。这样，服务基站可以根据来自用户设备的上报信息而确定第一基站集合以及可选的第二基站集合，并且将来自用户设备的数据信息通过例如X2接口发送至这些基站。
这里，应指出，以上被描述为在基站端或用户设备端执行的操作并不限于仅在所描述的这一端执行，而是可替代地在另一端执行，只要将执行操作所需要的信息发送至另一端即可。因此，本公开不特别限制执行各个操作的主体，本领域技术人员可以根据执行本公开的技术方案时的具体情况(包括处理能力、通信负荷、功耗等因素)而选择在合适的一端执行相应的操作，以便实现系统性能最优。
此外，还应指出，虽然以上分别描述了各个实施例中的电子设备的功能配置，但是这仅是示例而非限制，并且本领域技术人员可以根据需要而对上述各个实施例中的功能进行添加、删除、组合、子组合和变更等，所有这样的变型应认为落入本公开的范围内。
为了进一步有利于对本公开的技术方案的整体理解，下面将参照图12描述本公开的总体工作流程。图12是示出根据本公开的实施例的整体方案的实现示例的交互流程图。在图12中，以V2X通信场景为例进行描述。
如图12所示，首先，响应于预定触发事件或者根据预定周期，发送车辆T-VUE向服务基站eNB发送调度请求SR，还可同时向服务基站eNB发送关于要发送的数据信息(V2X消息)的优先级的优先级指示。
然后，服务基站eNB通过UL grant为发送车辆T-VUE分配上行资源。同时，根据所接收到的优先级指示，如果指示该V2X消息是低优先级的，则说明可以采用SC-PTM广播方式，从而服务基站eNB还将所分配的组标识符(GroupID)发送给发送车辆T-VUE。
然后，发送车辆T-VUE对组标识符进行广播。由于仅在发送车辆周围一定范围的接收车辆R-VUE才能接收到该组标识符进而接收和解码利用GroupID加扰后的数据信息，因此能够避免不必要的接收。
接下来，发送车辆T-VUE将数据信息与所确定的基站集合(包括第一基站集合以及可选的第二基站集合)或者与数据信息的影响范围dm和地理位置信息或下行信道质量测量结果等一起上报至服务基站eNB。
接下来，服务基站eNB根据所接收到的上报信息而将数据信息和标识发送至相应基站，例如，对于组播/广播基站，发送标识“1”，而对于缓存基站，发送标识“0”，从而接收到相应标识符的基站可以对所接收到的数据信息进行组播/广播或者缓存。此外，应指出，如上所述，在低优先级数据信息的情况下，发送至组播/广播基站和缓存基站的数据信息可以是已利用组标识符加扰后的数据信息，或者服务基站也可以将原始数据信息和组标识符一起发送至各个基站，从而各个基站在进行组播/广播时利用接收到的组标识符对数据信息进行加扰并组播/广播。此外，为了保证新加入的接收车辆能够正确接收和和解调数据信息，发送车辆可周期性地广播其组标识符。
应指出，参照图12描述的整体交互流程仅是示例，本领域技术人员可以根据本公开的原理而对该交互流程进行修改。此外，以上描述的各个操作的顺序并不特别限制，而是可根据实际需要而进行适当地调整，例如，可以并行地或者独立地执行。
与上述设备实施例相对应地，本公开还描述了以下方法实施例。
图13是示出根据本公开的实施例的无线通信中的用户设备端的方法的过程示例的流程图。
如图13所示，根据该实施例的方法1300开始于步骤S1301。在步骤S1301中，测量用户设备的服务基站和邻近基站的下行信道质量。该下行信道质量可包括CQI、RSRP和RSRQ中的一个或多个。
然后，该方法进行到步骤S1302。在步骤S1302中，基于所测量的下行信道质量而从服务基站和邻近基站中确定第一基站集合，该第一基站集合表示要对数据信息进行组播或广播的基站集合。具体地，可基于下行信道质量的变化趋势及幅值、并结合数据信息的影响范围来确定第一基站集合。具体的确定过程可参见以上相应位置的描述，在此不再重复。
优选地，该方法还可包括用于基于所测量的下行信道质量而确定第二基站集合的步骤，生成包括数据信息、所确定的第一基站集合以及可选的第二基站 集合的报告的步骤，对组标识符进行广播的步骤，以及发送所生成的报告的步骤等。
应理解，这里描述的方法实施例是与以上参照图2描述的电子设备200的实施例相对应的，因此，在此未详细描述的内容可参见以上相应位置的描述，在此不再重复。
图14是示出根据本公开的实施例的无线通信中的基站端的方法的过程示例的流程图。
如图14所示，根据该实施例的方法开始于步骤S1401。在步骤S1401中，根据来自该基站服务的用户设备的报告而确定相应的数据信息和第一基站集合。
然后，该方法进行到步骤S1402。在步骤S1402中，将数据信息发送至第一基站集合中的各个基站。
优选地，该方法还包括根据报告信息确定第二基站集合以及将数据信息发送至第二基站集合中的各个基站的步骤，为用户设备分配组标识符的步骤，以及利用组标识符对数据信息进行加扰的步骤等。此外，优选地，在发送数据信息的同时，还将指示该基站是组播/广播基站还是缓存基站的标识发送至相应基站，以指示该基站是否要对接收到的数据信息进行组播/广播。
应理解，这里描述的方法实施例是与以上参照图6描述的基站端的电子设备600的实施例相对应的，因此，在此未详细描述的内容可参见以上相应位置的描述，在此不再重复。
图15是示出根据本公开的另一实施例的基站端的方法的过程示例的流程图。
如图15所示，该方法开始于步骤S1501。在步骤S1501中，根据基站服务的用户设备的移动位置所属的子区域和来自用户设备的数据信息的影响范围，确定第一子区域集合，该子区域是通过对小区覆盖范围进行划分而得到的。优选地，可基于当前地理位置信息和移动速度等信息来估计用户设备的移动位置，或者也可基于用户设备报告的下行信道质量测量结果和基站间距离、利用三角测量方法来估计用户设备的移动位置。
然后，该方法进行到步骤S1502。在步骤S1502中，根据第一子区域集合 中的各个子区域所属的小区，确定第一基站集合，以便在随后的步骤中将数据信息发送至第一基站集合中的各个基站。
优选地，该方法还可包括用于基于下行信道质量测量结果确定第二基站集合以及将数据信息发送至第二基站集合中的各个基站的步骤。
应理解，这里的方法实施例是与以上参照图8描述的基站端的电子设备800的实施例相对应的，因此，在此未详细描述的内容可参见以上相应位置的描述，在此不再重复。
图16是示出根据本公开的另一实施例的无线通信中的用户设备端的方法的过程示例的流程图。
如图16所示，根据该实施例的方法1600开始于步骤S1601。在步骤S1601中，生成至少包括用户设备的数据信息的影响范围的报告。
然后，该方法进行到步骤S1602。在步骤S1602中，将所生成的报告信息发送至用户设备的服务基站。
优选地，该报告还可包括用户设备的当前位置信息、移动速度、对于周围基站的下行信道质量测量结果等，以供服务基站确定用户设备的移动位置，然后结合数据信息的影响范围确定第一子区域集合，进而确定第一基站集合。
应理解，这里描述的方法实施例是与以上参照图10描述的用户设备端的电子设备1000的实施例相对应的，因此，在此未详细描述的内容可参见以上相应位置的描述，在此不再重复。
根据上述本公开的实施例，本公开的技术方案至少可以实现以下优点中的一个或多个：
(1)通过基于下行信道质量测量结果来确定组播/广播基站集合，解决了在地理位置信息不可用的情况下的问题，并且还克服了现有技术中由基站维护所有车辆的位置信息以此来确定组播/广播基站集合所导致的信令开销大的缺陷；
(2)通过确定缓存基站集合以将数据信息预先发送至这些基站进行缓存，一旦这些基站变为组播/广播基站，可以立即进行组播/广播，减小了时延；
(3)通过取代基于具体地理位置的变化而基于子区域(zone)的变化来确定组播/广播基站的变化，可以避免过于频繁地确定组播/广播基站，从而减 轻了处理负荷，这对于用户设备的地理位置频繁变化的情况尤其有利；以及
(4)通过根据数据信息的优先级而选择不同的组播方式，并且为发送低优先级数据信息的用户设备分配组标识符以进行广播，不仅可以保证高优先级数据信息的接收性能，还可以避免不必要的接收，降低设备功耗。
应理解，根据本公开的实施例的存储介质和程序产品中的机器可执行的指令还可以被配置为执行与上述装置实施例相对应的方法，因此在此未详细描述的内容可参考先前相应位置的描述，在此不再重复进行描述。

另外，还应该指出的是，上述系列处理和装置也可以通过软件和/或固件实现。在通过软件和/或固件实现的情况下，从存储介质或网络向具有专用硬件结构的计算机，例如图17所示的通用个人计算机1700安装构成该软件的程序，该计算机在安装有各种程序时，能够执行各种功能等等。图17是示出作为本公开的实施例中可采用的信息处理设备的个人计算机的示例结构的框图。

以下将参照图18至图21描述根据本公开的应用示例。
[关于基站的应用示例]
(第一应用示例)
图18是示出可以应用本公开内容的技术的eNB的示意性配置的第一示例的框图。eNB 1800包括一个或多个天线1810以及基站设备1820。基站设备 1820和每个天线1810可以经由RF线缆彼此连接。

基站设备1950包括控制器1951、存储器1952、网络接口1953、无线通信接口1955以及连接接口1957。控制器1951、存储器1952和网络接口1953与参照图18描述的控制器1821、存储器1822和网络接口1823相同。
无线通信接口1955支持任何蜂窝通信方案(诸如LTE和LTE-先进)，并且经由RRH 1960和天线1940来提供到位于与RRH 1960对应的扇区中的终端的无线通信。无线通信接口1955通常可以包括例如BB处理器1956。除了BB 处理器1956经由连接接口1957连接到RRH 1960的RF电路1964之外，BB处理器1956与参照图18描述的BB处理器1826相同。如图19所示，无线通信接口1955可以包括多个BB处理器1956。例如，多个BB处理器1956可以与eNB 1930使用的多个频段兼容。虽然图19示出其中无线通信接口1955包括多个BB处理器1956的示例，但是无线通信接口1955也可以包括单个BB处理器1956。
连接接口1957为用于将基站设备1950(无线通信接口1955)连接至RRH1960的接口。连接接口1957还可以为用于将基站设备1950(无线通信接口1955)连接至RRH 1960的上述高速线路中的通信的通信模块。
