Description

监听授权辅助接入小区的方法、设备和基站 技术领域
本发明实施例涉及通信技术领域，尤其涉及一种监听授权辅助接入小区的方法、设备和基站。
背景技术
随着移动通信业务数据量急剧提升，无线通信频谱越来越紧张，近年来，由于无线电视等业务逐步退出市场，腾出的一些频谱，由于这些频谱资源未经电气和电子工程师协会(英文：Institute of Electrical and Electronics Engineers，简称：IEEE)分配给第三代合作伙伴项目(英文：the 3rd Generation Partnership Project，简称：3GPP)使用，所以对3GPP来说，属于未授权(unlicensed)频谱，也称为非标频谱。将未授权频谱用于部署小站，可以为宏站分流数据负荷，优化无线网络性能，提升用户体验。如果使用未授权频谱传输多媒体广播组播业务(英文：Multimedia Broadcast Multicast Service，简称：MBMS)业务，可以有效利用未授权频谱，节约授权(license)频谱用于其它更高优先级的业务。
由于未授权频谱并非3GPP专用，而是属于公共频谱，任何人、任何机构都可以使用该频谱发送信息，所以对于3GPP而言，未授权频谱并非随时都可用。3GPP需要与其它系统竞争其使用权，竞争成功后可以在有限的时间内使用，使用完毕，必须释放。
使用未授权频谱的小区被称为授权辅助接入(英文：License Assist Access，简称：LAA)小区，由于未授权频谱并非随时都可用，所以为了使用LAA小区进行通信，用户设备(英文：User Equipment，简称，UE)必须首先确认LAA小区是否可用。在一种现有技术中，基站(如eNB)先通知UE“哪些LAA小区可能可以使用”，UE收到该通知后，随时监听这些LAA小区是否可以使用，一旦发现可以使用的LAA小区，马上使用这些LAA小区传送数据。但是，上述技术中，UE需要不间断地监听这些LAA小区，UE的耗电量很大。
在一种现有技术中，基站先通知UE“哪些LAA小区可能可以使用”，UE收到该通知后，持续接收这些LAA小区的信号。当某个LAA小区可用时，基站采用“跨载波调度”的方式，即通过普通小区调度LAA小区的资源，向UE传送数据。具体的，基站在普通小区向UE发送下行控制信息(英文：Downlink Control Information，简称：DCI)，DCI中包含所述数据的调制与编码方式(英文：Modulation and Coding Scheme，简称：MCS)、所述数据所在的LAA小区标识、在LAA小区内的物理资源位置等，UE根据这些信息去对应的LAA小区解调数据。上述技术中，UE虽然不需要UE连续监听LAA小区是否可用，但是仍然需要UE持续接收LAA小区的信号，否则当普通小区通知UE“LAA小区有数据”时，UE没有准备，来不及接收LAA小区的数据。
由此可见，现有技术中，UE需要连续不断地监听或者接收LAA小区的信号，耗电量很大。

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作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。
应理解，本发明实施例的技术方案可应用于图1所示的场景，在普通小区中包括多个LLA小区，其中普通小区的基站为宏站，LLA小区的基站为小站(也称微站)，普通小区使用的是授权频谱，LLA小区使用的是非授权频谱，普通小区的基站能够通过LLA小区与用户设备传输数据，从而能够为普通小区的基站分流数据负荷，优化无线网络性能。

步骤101、用户设备接收基站发送的通知信令，所述通知信令用于通知所述用户设备监听目标LAA小区。
步骤102、所述用户设备对目标LAA小区的指定信号进行监听。
其中，若只配置了一个LAA小区时，基站仅通知信令即可，当存在多个LAA小区时，基站发送的通知信令中还包括目标LAA小区的特征信息，所述用户设备先根据所述特征信息在所述多个LAA小区中确定所述目标LAA小区，再对所述目标LAA小区的指定信号进行监听。
对应的，本发明实施例还提供另一种监听授权辅助接入小区的方法，由基站执行，该基站为普通小区的基站，如图3所示，该方法包括：
步骤201、基站确定将要参与LAA小区的频率竞争。
步骤202、所述基站向至少一个用户设备发送通知信令，所述通知信令用于通知所述至少一个用户设备监听目标LAA小区，以便所述至少一个用户设备对所述目标LAA小区的指定信号进行监听。
其中，若只配置了一个LAA小区时，基站仅通知信令即可，当存在多个LAA小区时，基站发送的通知信令中还包括目标LAA小区的特征信息，以便所述用户设备先根据所述特征信息在所述多个LAA小区中确定所述目标LAA小区，再对所述目标LAA小区的指定信号进行监听。
或者，在另一种实现方式中，本实施例提供的监听授权辅助接入小区的方法，由基站执行，该基站为普通小区的基站，如图4所示，包括：
步骤301、基站进行目标LAA小区的频率竞争。
步骤302、若竞争所述目标LAA小区失败，所述基站获取成功竞争到所述目标LAA小区的网元预计使用所述目标LAA小区的使用时间。
步骤303、所述基站向至少一个用户设备发送通知信令，所述通知信令包括所述使用时间，用于指示所述至少一个用户设备在所述使用时间内不对所述目标LAA小区进行监听。
其中，若只配置了一个LAA小区时，基站发送的通知信令可以不包括目标LAA小区的特征信息，当存在多个LAA小区时，基站发送的通知信令中还包括目标LAA小区的特征信息，以便所述至少一个用户设备先根据所述特征信息在所述多个LAA小区中确定所述目标LAA小区，并在所述使用时间内不对所述目标LAA小区进行监听。
对应的，本实施例还提供另一种监听授权辅助接入小区的方法，由用户设备执行，如图5所示，该方法包括：
步骤401、用户设备接收基站发送的通知信令，所述通知信令包括目标LAA小区的使用时间；其中，所述使用时间是所述基站在竞争所述目标LAA小区失败后，从成功竞争到所述目标LAA小区的网元获取的所述网元预计使用所述目标LAA小区的使用时间。
步骤402、所述用户设备在所述使用时间内不对所述目标LAA小区进行 监听。
其中，若只配置了一个LAA小区时，基站发送的通知信令可以不包括目标LAA小区的特征信息，当存在多个LAA小区时，基站发送的通知信令中还包括目标LAA小区的特征信息，所述至少一个用户设备根据所述特征信息在所述多个LAA小区中确定所述目标LAA小区，并在所述使用时间内不对所述目标LAA小区进行监听。
另外，本发明实施例中的所述目标LAA小区可以是某个普通小区中的一个或多个LAA小区。
为了使本领域技术人员能够更清楚地理解本发明实施例提供的技术方案，下面通过具体的实施例，对本发明的实施例提供的监听授权辅助接入小区的方法进行详细说明，如图6所示，该方法包括：
步骤501、基站确定将要参与LAA小区的频率竞争后，向至少一个用户设备发送通知信令。
其中，该通知信令用于告知用户设备所述基站将要参与LAA小区的频率竞争，通知用户设备对目标LAA小区进行监听，如果基站所述在普通小区中只配置了一个LAA小区，那么该通知信令中不需要携带其他信息，用户收到通知信令后默认监听这唯一的LAA小区，若存在多个LAA小区时，该通知信令中包括目标LAA小区的特征信息(即基站将要竞争的目标LAA小区的特征信息)，其中，目标LAA小区可以是一个或者多个LAA小区，该特征信息可以包括这些目标LAA小区的标识(例如ID)或者频点，该特征信息用于用户设备确定哪些LAA小区是目标LAA小区。
可选的，该通知信令可以是广播信令，也可以是专用信令。该通知信令如果是过专用信令，基站需要选择一部分用户设备来通知，但是由于只通知了一部分用户设备，在竞争成功后，基站也只能通过竞争到的LAA小区与所述一部分用户设备进行传输数据。当然，这一限制只在本次竞争成功后有效，下一次竞争成功后则此限制无效。该通知信令如果是通过广播信令，基站就可以在竞争成功后与任意用户设备传输数据。
步骤502、用户设备接收基站发送的通知信令。
步骤503、用户设备对所述目标LAA小区的指定信号进行监听。
具体的，以存在多个LAA小区为例，通知信令中包括目标LAA小区 的特征信息，则用户设备在收到通知信令后，首先，根据通知信令中的目标LAA小区的标识或频点等特征信息找到对应的LAA小区，然后对这些LAA小区的指定信号进行监听。
其中，若在第一预设时间T1内监听到所述指定信号，则执行步骤504～步骤505；若在第一预设时间T1内未监听到所述指定信号，则执行步骤506。
示例性的，该指定信号可以是前导(preamble)序列。值得注意的是，如果接收方事先不知道发送方会发送哪一个前导序列，就只能盲检，以确定是否发送了信号，以及发送了哪一个前导序列，处理复杂度高，因此，为了避免盲检，降低处理复杂度，加快UE用户设备对目标LAA小区监听的速度，基站可以将自己准备在目标LAA小区发送的用于作为竞争成功通知信号的前导序列的索引事先告诉用户设备，这样可以降低处理复杂度，从而进一步地降低了用户设备的耗电量。
进一步的，为了进一步减少用户设备盲检复杂度，前导序列只在设定的一个或多个OFDM符号位置开始。
因此，可选的，步骤501中的通知信令还可以包括该前导序列的索引。此时，用户设备可以在根据特征信息确定所述目标LAA小区后，可以根据所述前导序列的索引对所述目标LAA小区的所述前导序列进行监听。
另外，基站在发送向用户设备发送通知信令后，由于该基站可能还在处理自身业务，或一些其他原因，导致该基站不会立即参与到LAA小区的频率竞争中。因此，可选的，可以在接收到所述通知信令后，间隔第二预设时间T2后，再对所述目标LAA小区的指定信号进行监听，例如，其过程可以如图7所示，普通小区的基站发送向用户设备发送通知信令，指示用户设备在目标LAA小区监听指定信号，在间隔T2时间后，用户设备开始了对目标LAA小区的指定信号的监听，从图7中可见，用户设备在T1内监听到了指定信号(图7中用黑色加粗竖线表示)，从而能够确定基站竞争目标LAA小区成功，该目标LAA小区是可用的。或者，如图7所示，用户设备在T1内没有监听到指定信号，则能够确定基站竞争目标LAA小区失败，该目标LAA小区是不可用的。
步骤504、用户设备确定竞争所述目标LAA小区成功，所述目标LAA 小区可用。
步骤505、基站与用户设备通过所述目标LAA小区传输数据。
步骤506、用户设备确定竞争所述目标LAA小区失败，所述目标LAA小区不可用。
本发明实施例提供一种监听授权辅助接入小区的方法，用户设备先接收基站发送的通知信令，该通知信令用于通知用户设备监听目标LAA小区，用户设备在收到通知信令后对该目标LAA小区的指定信号进行监听，其中，若基站所在的普通小区中存在多个LAA小区，该通知信令中还包括目标LAA小区的特征信息，用户设备根据该特征信息能够在多个LAA小区中确定目标LAA小区，并对该目标LAA小区的指定信号进行监听，由此可见，本发明实施例不需要连续监听或接收LAA小区的信号，只在基站指示时才进行监听，能够解决现有技术中由于用户设备需要不断地监听或者接收LAA小区的信号导致的耗电量大的问题，从而能够降低用户设备的耗电量。进一步的，在用户设备对该目标LAA小区的指定信号进行监听之前，可以预先获取该指定信号的索引，例如该指定信号为前导序列时，预先从基站获取该前导序列的索引，使得用户设备能够根据该前导序列的索引快速定位要监听的前导序列，从而能够进一步地降低用户设备的耗电量。
在另一种实现方式中，提供另一种监听授权辅助接入小区的方法，如图8所示，该方法包括：
步骤701、基站进行目标LAA小区的频率竞争。
其中，若基站竞争所述目标LAA小区成功，则执行步骤702，若竞争所述目标LAA小区失败则执行步骤703～705。
步骤702、基站与至少一个用户设备通过所述目标LAA小区传输数据。
其中，所述至少一个用户设备可以是对目标LAA小区的指定信号持续保持监听的用户设备，当基站竞争所述目标LAA小区成功时，所述至少一个用户设备会接收到所述目标LAA小区的指定信号，从而确定所述目标LAA小区可用，进而基站与所述至少一个用户设备能够通过所述目标LAA小区传输数据。其中，关于所述指定信号，可以参照步骤503中 的指定信号，此处不再赘述。
步骤703、基站获取成功竞争到所述目标LAA小区的网元预计使用所述目标LAA小区的使用时间。
步骤704、基站向至少一个用户设备发送通知信令，所述通知信令包括所述目标LAA小区的特征信息和所述使用时间。
当然，如果基站所在的普通小区中只配置了一个LAA小区，该通知信令中可以不包括目标LAA小区的特征信息。
步骤705、所述至少一个用户设备在所述使用时间内不对所述目标LAA小区进行监听。
其中，所述至少一个用户设备是对目标LAA小区的指定信号持续保持监听的用户设备，当所述至少一个用户设备接收到通知信令后，根据通知信令中的所述使用时间，在所述使用时间内不对所述目标LAA小区进行监听。或者，所述至少一个用户设备不对目标LAA小区进行持续监听，只是在基站指示后，或者其他需要坚挺的情况下对目标LAA小区进行监听，在监听时根据之前收到的所述使用时间，在该使用时间内不对所述目标LAA小区进行监听。
其过程可以如图9所示，以用户设备对目标LAA小区保持持续监听为例，当用户设备接收到通知信令后，从通知信令中获取不必监听目标LAA小区的时间T1，并在该T1内停止对目标LAA小区进行监听。
本发明实施例还提供另一种监听授权辅助接入小区的方法，基站在进行目标LAA小区的频率竞争失败后，获取成功竞争到目标LAA小区的网元预计使用目标LAA小区的使用时间，并向至少一个用户设备发送通知信令，该通知信令包括所述使用时间，用于指示正在监听这些目标LAA小区的该至少一个用户设备在该使用时间内不对目标LAA小区进行监听，其中，若基站所在的普通小区中存在多个LAA小区，该通知信令中还包括目标LAA小区的特征信息，收到通知信令的用户设备根据该特征信息能够在多个LAA小区中确定目标LAA小区，并对在该使用时间内不对目标LAA小区进行监听，由此可见，本发明实施例中，用户设备收到基站的通知信令后，在该通知信令指示的时间内对LAA小区不进行监听，能够解决现有技术中由于用户设备需要不断地监听或者接收LAA小区的信 号导致的耗电量大的问题，从而能够降低用户设备的耗电量
除此之外，本发明实施例还提供一种广播业务的数据读取方法，如图10所示，该方法包括：
步骤1001、基站向用户设备发送系统广播消息，所述系统消息广播包括业务信息列表和子帧集合信息列表。
其中，业务信息列表包括一个或多个业务的信息，每个业务的信息包括该业务对应的组-无线网络临时标识(英文：Group Radio Network Temporary Identity，简称G-RNTI)，以及该业务对应的子帧集合，其中该业务对应的子帧集合可以理解为该业务所分布的可能的子帧的集合；
子帧集合信息列表中包括一个或多个子帧集合的信息，每个子帧集合的信息包括该子帧集合的无线帧周期、偏移量以及比特位图，其中，无线帧周期和偏移量用于指示该子帧集合所在的无线帧，比特位图用于指示在所述无线帧中的哪些子帧为该子帧集合中的子帧。
步骤1002、用户设备根据业务信息列表确定目标业务对应的G-RNTI和子帧集合。
步骤1003、用户设备利用目标业务对应的G-RNTI，在目标业务对应的子帧集合内进行盲检，获取目标业务的数据。
示例性的，假设用户设备的目标业务为业务A，用户设备该从基站接收到系统消息广播中的业务信息列表和子帧集合信息列表分别如表1和表2所示。
表1
业务 G-RNTI 子帧集合
业务A G-RNTI A 子帧集合1
业务B G-RNTI B 子帧集合2
表2
子帧集合 周期(无线帧) 偏移量(无线帧) 比特位图
子帧集合1 4 0 0110001100
子帧集合2 8 1 0110001000
则该用户设备根据表1可以确定其目标业务，即业务A对应的G-RNTI为G-RNTI A，对应的子帧集合为子帧集合1。根据表2可知，子帧集合1中的子帧所在的无线帧的周期为4，偏移量为0，所以子帧集合1中的子帧所在的无线帧应为第0、4、8、12、16……号无线帧，根据比特位图0110001100可知子帧集合1中的子帧应为第0、4、8、12、16……号无线帧中的第1、2、6、7号子帧。用户设备利用G-RNTI A在第0、4、8、12、16……号无线帧中的第1、2、6、7号子帧中进行盲检就能够获取业务A的数据。
图11为无线帧的结构图，如图11所示，无线帧0～19中的每个无线帧中都包括10个子帧，即子帧0～9。子帧集合1包括第0、4、8、12、16……号无线帧中的第1、2、6、7号子帧(用斜线部分表示)，子帧集合2包括第1、9、17…号无线帧的第1、2、6号子帧(用相反的斜线部分表示)。
可见，本实施例中，可以将业务限定在一个有限的子帧集合内，用户设备只需检测一部分子帧就可以读取业务数据，这样可以降低用户设备的耗电量。另外，上述出现的各个参数仅仅为示例性的，包括但不限于此，上述业务可以是多媒体广播组播(英文：Multimedia Broadcast Multicast Service，简称：MBMS)业务，子帧可以是多媒体广播组播单频网络(英文：Multimedia Broadcast multicast service Single Frequency Network，简称：MBSFN)子帧。
或者，本发明实施例还提供另一种广播业务的数据读取方法，如图12所示，该方法包括：
步骤1201、基站向用户设备发送系统消息广播，所述系统消息广播包括MBMS调度信息(英文：MBMS Schedule Information，简称：MSI)的描述信息和业务信息列表。
其中，MSI的描述信息包括MSI的无线帧周期、偏移量以及MSI所在的子帧号，或者其它信息能让UE找到MSI所在的子帧。业务信息列表中包括一个或多个业务的信息，每个业务的信息包括该业务的G-RNTI和逻辑信道号。
步骤1202、用户设备根据MSI的描述信息找到MSI所在的子帧并读取MSI，所述MSI用于指示一个或多个业务对应的G-RNTI可能出现在哪 些子帧。
步骤1203、用户设备根据MSI确定可能出现目标业务对应的G-RNTI的子帧。
步骤1204、用户设备在可能出现目标业务对应的G-RNTI的子帧中获取使用目标业务对应的G-RNTI寻址的数据块。
步骤1205、用户设备利用目标业务的逻辑信道号在使用目标业务对应的G-RNTI寻址的数据块中获取目标业务的数据。
示例性的，假设用户设备的目标业务为业务B，用户设备该从基站接收到系统消息广播中的MSI描述信息和业务信息列表分别如表3和表4所示。
表3
MSI的描述信息 周期(无线帧) 偏移量 所在子帧号
MSI所在子帧 32 0 #0
表4
业务 G-RNTI 逻辑信道号
业务A G-RNTI A 3
业务B G-RNTI B 5
业务C G-RNTI B 9
用户设备根据MSI所在的无线帧周期为32，偏移量为0，以及所在子帧号为#0可知MSI位于第0、32、64…号无线帧的第0号子帧，而后，用户设备在第0、32、64…号无线帧的第0号子帧上读取MSI，示例性的，假设第0号无线帧上的MSI指示G-RNTI A可能在第0-18号子帧出现，G-RNTI B可能在第19-35号子帧出现，如图13所示，一共有32个无线帧，每个无线帧有10个子帧，所以共有320个子帧，编号0-319，其中0号子帧(用斜线表示)中的方块表示MSI，这里MSI仅指示G-RNTI A 18即可表示G-RNTI A可能在第0-18号子帧出现，指示G-RNTI A 35即可表示G-RNTI B可能在第19-35号子帧出现。
用户设备根据表4中的信息可知目标业务，即业务B的G-RNTI为G-RNTI B，逻辑信道号为5，因此用户设备根据MSI的指示在第19-35号 子帧中获取使用G-RNTI B寻址的数据块，最后用户设备根据逻辑信道号5在使用G-RNTI B寻址的数据块中获取业务B的数据。
另外，第0、32、64…号无线帧上的MSI可能是不同的，例如图13所示，第32号无线帧的第0号子帧上的MSI指示G-RNTI A可能在第0-17号子帧出现，G-RNTI B可能在第18-42号子帧出现。用户设备读取该MSI并获取目标业务的数据的方法与前述相同，不再赘述。
可见，本实施例中，可以将业务限定在一个有限的子帧集合内，用户设备只需检测一部分子帧就可以读取业务数据，这样可以降低用户设备的耗电量。另外，上述出现的各个参数仅仅为示例性的，包括但不限于此，上述业务可以MBMS业务，子帧可以是MBSFN子帧。
