Description

上行信息传输方法、基站与用户设备 技术领域
本发明实施例涉及数据传输技术，尤其涉及一种上行信息传输方法、基站与用户设备。
背景技术
为缓解频谱资源不足，第三代移动通信伙伴组织(3rd Generation Partnership Project，3GPP)采用非授权频谱提供无线通信服务。根据授权频谱小区与非授权频谱小区是否共站署，现有如下两种部署方式：方式一、授权频谱小区与非授权频谱小区共站部署，此时，对于一个具体的基站，该基站下的小区包括授权频谱小区和非授权频谱小区；方式二、授权频谱小区不与非授权频谱小区共站部署，此时，至少存在一个基站，该基站下的小区均为非授权频谱小区。
载波聚合(Carrier Aggregation，CA)技术中，用户设备(User Equipment，UE)同时使用该基站的多个小区传输数据，从而提高数据传输速度。多个小区中，其中一个是主小区(Primary Cell，PCell)，其他是辅小区(Secondary Cell，SCell)。一般来说，CA可分为基站内小区聚合、基站间小区聚合等。基站内小区聚合是指对于一个UE，聚合的服务小区属于同一个基站；基站间小区聚合是指对于同一个UE，聚合的服务小区属于多个不同的基站(当前标准协议只支持两个基站)，其中，PCell所在的服务基站是主基站(Master eNB，MeNB)，其他服务基站是辅基站(Secondary，SeNB)，辅基站下的一个或多个SCell中有一个小区是主辅小区(Primary Secondary Cell，PSCell)。一般来说，上行信息包括上行控制信息与上行数据信息，SCell用于传输上行数据信息，而PCell除了传输上行数据信息外，还传输辅助其他SCell传输上行数据信息的上行控制信息。
当采用上述方式一部署非授权频谱小区时，上行信息传输过程中，聚合的服务小区中的非授权频谱小区作为SCell，只传输UE的上行数据信息，UE所有的上行控制信息均通过授权频谱小区PCell传输，若PCell是一个窄 带小区，由于窄带小区容量有限，则会导致PCell容量受限的问题，PCell传输的上行控制信息有限，进而影响SCell传输上行数据信息，导致上行信息的传输可靠性差；当采用上述方式二部署非授权频谱小区时，一个基站下的所有小区均为非授权频谱小区。目前，还未针对这种场景提出上行信息传输方法。因此，CA技术中，如何传输上行信息实为业界亟待解决的问题。
发明内容
本发明实施例提供一种上行信息传输方法、基站与用户设备，通过把上行信息分散到小区组中的多个小区传输，实现上行信息的高可靠性传输。
一方面，本发明实施例提供一种上行信息传输方法，所述方法是从用户设备的角度描述，该方法中，用户设备接收基站发送的小区组的配置信息，并根据配置信息通过小区组发送上行信息，从而把上行信息分散到小区组中的多个小区传输，实现上行信息的高可靠性传输。同时，将该方法应用于非授权小区与授权小区共站部署的场景，能解决Pcell容量受限的问题；将该方法应用于非授权频谱小区不与授权频谱小区共站部署的场景，可以实现这种场景下的上行信息传输。。
在一种可能的实现方式中，对于小区组中的一个具体的小区，通过将该小区的上行信息分散给该小区自身，或者其他小区，从而将整个小区组的上行信息分散到小区组中的多个小区传输，解决了PCell容量受限的问题。此时，

在一种可能的实现方式中，所述UE在一个多播控制信道MCCH周期中，通过所述第三小区接收所述基站发送的单小区多播控制信道SC-MCCH消息之后，还包括：所述UE根据所述SC-MCCH，确定所述基站发送SC-MTCH信息的SC-MTCH窗口；所述UE根据SC-PTM优先级，从所述小区组中确定出第四小区；所述UE通过所述第四小区接收所述基站在所述SC-MTCH内发送的SC-MTCH信息。

具体实施方式
一般来说，可根据授权频谱小区与非授权频谱小区是否共站署，将非授权频谱的部署方式分为如下两种：方式一、授权频谱小区与非授权频谱小区共站部署；方式二、授权频谱小区不与非授权频谱小区共站部署。将非授权频谱小区引入CA技术中，上行信息(包括上行控制信息和上行数据信息)传输过程中，当采用上述方式一时，聚合服务的小区中的SCell，主要指非授权频谱小区只传输上行数据信息，所有小区的上行控制信息均通过授权频谱小区PCell传输，若PCell是一个窄带小区，由于窄带小区容量有限，则会导致PCell容量受限的问题，PCell传输的上行控制信息有限，进而影响SCell传输上行数据信息，导致上行信息的传输可靠性差；当采用上述方式二时，一个基站下的所有小区均为非授权频谱小区，目前，还未提出这种场景下的上行信息传输方法。
针对上述方式一，为解决PCell容量受限的问题，目前一种可能的方式减少上行信息的上报。以上行信息具体为上行控制信息、上行控制信息具体 为信道状态指示(Channel Quality Indicator，CQI)为例，为了使得eNB实时知道下行信道的各个子载波的衰减情况，一般要求UE每5ms上报一次CQI，以便eNB作出最佳的下行调度决策。但是由于PCell容量受限，因此减少CQI的上报，UE每20ms上报一次。如此一来，基站作下行调度决策时的依据为20ms之前的信道状态，与当前的信道状态偏差较大，无法选择最小的子载波传输下行数据，进而影响了下行吞吐量。
有鉴于此，本发明实例提供上行信息传输方法、基站与用户设备，通过把上行信息分散到小区组中的多个小区传输，实现上行信息的高可靠性传输。
本文中描述的技术可用于各种通信***，例如当前2G，3G通信***和下一代通信***，例如全球移动通信***(Global System for Mobile communications，GSM)，码分多址(Code Division Multiple Access，CDMA)***，时分多址(Time Division Multiple Access，TDMA)***，宽带码分多址(Wideband Code Division Multiple Access Wireless，WCDMA)，频分多址(Frequency Division Multiple Addressing，FDMA)***，正交频分多址(Orthogonal Frequency-Division Multiple Access，OFDMA)***，单载波FDMA(SC-FDMA)***，通用分组无线业务(General Packet Radio Service，GPRS)***，长期演进(Long Term Evolution，LTE)***，E-UTRA***以及其他此类通信***。
本申请中涉及的终端，可以是有线终端，也可以是无线终端，该无线终端可以是指向用户提供语音和/或数据连通性的设备，具有无线连接功能的手持式设备、或连接到无线调制解调器的其他处理设备。无线终端可以经无线接入网(例如，RAN，Radio Access Network)与一个或多个核心网进行通信，无线终端可以是移动终端，如移动电话(或称为“蜂窝”电话)和具有移动终端的计算机，例如，可以是便携式、袖珍式、手持式、计算机内置的或者车载的移动装置，它们与无线接入网交换语言和/或数据。例如，个人通信业务(Personal Communication Service，PCS)电话、无绳电话、会话发起协议(SIP)话机、无线本地环路(Wireless Local Loop，WLL)站、个人数字助理(Personal Digital Assistant，PDA)等设备。无线终端也可以称为***、订户单元(Subscriber Unit)、订户站(Subscriber Station)，移动站(Mobile Station)、 移动台(Mobile)、远程站(Remote Station)、远程终端(Remote Terminal)、接入终端(Access Terminal)、用户终端(User Terminal)、用户代理(User Agent)、用户设备(User Device)、或用户装备(User Equipment)。
本申请中涉及的基站可以是指接入网中在空中接口上通过一个或多个扇区与无线终端通信的设备。基站可用于将收到的空中帧与IP分组进行相互转换，作为无线终端与接入网的其余部分之间的路由器，其中接入网的其余部分可包括网际协议(IP)网络。基站还可协调对空中接口的属性管理。例如，基站可以是GSM或CDMA中的基站(Base Transceiver Station，BTS)，也可以是WCDMA中的基站(NodeB)，还可以是LTE中的演进型基站(NodeB或eNB或e-NodeB，evolutional Node B)，本申请并不限定。
下面，为描述方便、清楚起见，以***架构具体为LTE***、基站具体为eNB为例对本发明技术方案进行详细描述。具体的，请参见图1。
图1为本发明上行信息传输方法所适用的网络架构示意图。如图1所示：网络中包括移动管理实体(Mobile Management Entity，MME)、服务网(Service Gateway，S-GW)、MeNB、SeNB等，MeNB具有分组数据汇聚协议(Packet Data Convergence Protocol，PDCP)层、无线链路控制(Radio Link Control，RLC)层、媒质接入控制(Radio Link Control，MAC)层，SeNB具有RLC层与MAC层。该网络架构中，非授权频谱小区可以采用上述的方式一部署，如MeNB下的小区中，以网格填充的小区为授权频谱小区，以竖线填充的小区为非授权频谱小区；非授权频谱小区也可以采用上述的方式二部署。例如，SeNB下的小区均为非授权频谱小区。
需要说明的是，虽然图1MeNB中，授权频谱小区与非频谱授权小区共站部署，SeNB中仅存在非授权频谱小区，MeNB与SeNB为主辅基站的关系。实质上，MeNB下也可仅存在非授权频谱小区，而SeNB下非授权频谱小区与授权频谱小区共站部署，而且，该两个基站独立部署，不存在主辅关系。
需要说明的是，本发明实施例提供的上行信息传输方法，可适用于非授权频谱小区单独组网的场景，也可适用于非授权频谱小区与授权频谱小区共同组网但不依赖授权频谱小区传输上行信息的场景，还可适用于非授权频谱小区和授权频谱小区共同组网但仅部分依赖于授权频谱小区传输上行信息的场景。下面，在图1的基础上对本发明通知方法进行详细说明，具体的，可 参见图2。
实施例一
图2为本发明上行信息传输方法实施例一的流程图。本实施例中，基站与终端交互，适用于需要通过小区组传输上行信息的场景。具体的，本实施例包括如下步骤：
101、基站为用户设备配置小区组。
本步骤中，基站从为用户设备提供聚合服务的小区中，选择出一个或多个配置成小区组，小区组中小区的数量小于或等于聚合服务的小区的数量，小区组中的一个或多个小区包括授权频谱小区和/或非授权频谱小区。
102、所述基站向所述UE发送配置信息，所述信息指示所述基站为所述UE配置的所述小区组。
在为UE配置好小区组后，基站将该小区组的配置信息发送给UE，其中，配置信息包括小区组中包含哪些小区、哪些物理资源位置、上行信息在哪些子帧上传输等信息。
103、UE通过所述小区组向所述基站发送上行信息。
在接收到配置信息后，UE通过小区组向基站发送上行信息。例如，UE通过小区组中的一个或多个非授权频谱小区向基站发送上行控制信息或上行数据信息。以发送上行控制信息为例，同一个小区组中的多个小区公共承担物理上行控制信道(Physical Uplink Control CHannel，PUCCH)，即上行控制信息传输的功能。其中，上行控制信息包括信道状态指示(Channel State Information，CSI)、秩指示(Rank Indication，RI)、预编码矩阵指示(Precoding Matrix Indicator，PMI)、混合自动重传请求(Hybrid Automatic Repeat reQuest，HARQ)等。
另外，上述小区组配置过程中，基站也可以非用户设备配置一个小区组集合并将小区组集合的配置信息发送给UE，该小区组集合中的每个小区组包含一个或多个小区。UE在接收到小区组集合的配置信息后，从小区组集合中选择出一个小区组，即从小区组集合中选择出一个或多个小区，并通过选择出的小区组向基站发送上行信息。如此一来，同一个小区组内的多个小区合作传输上行数据信息，以及上行传输数据信息所需的上行控制信息。小区组与小区组之间是独立工作的。
本发明实施例提供的上行信息传输方法，基站为UE配置小区组，并将小区组的配置信息发送给UE，使得UE通过小区组发送上行信息，从而把上行信息分散到小区组中的多个小区传输，实现上行信息的高可靠性传输。同时，将该方法应用于非授权小区与授权小区共站部署的场景，能解决Pcell容量受限的问题；将该方法应用于非授权频谱小区不与授权频谱小区共站部署的场景，可以实现这种场景下的上行信息传输。
下面，用不同的实施例对本发明上行信息传输方法进行详细说明。具体的，可参见下述的实施例二至实施例十一。
实施例二
本实例中，所述上行信息包括第一小区的上行信息，所述UE通过所述小区组向所述基站发送上行信息，包括：所述UE通过所述第一小区向所述基站发送所述第一小区的上行信息；或者，所述UE通过第二小区向所述基站发送所述第一小区的上行信息；其中，所述第一小区为所述小区组中的小区，所述第二小区为所述小区组中除所述第一小区之外的其他小区。也就是说，同一个上报周期内，一个第一小区的上行信息可以通过自身，即第一小区上报，也可以通过第二小区上报，例如，在第一个上报周期内，第一小区的上行信息通过第一小区上报，在第二个上报周期内，第一小区的上行信息通过第二小区上报。另外，当第二小区为非授权频谱小区时，在通过第二小区传输第一小区的上行信息之前，还需要确定出第二小区为可用的授权频谱小区。
具体的，以上行信息具体为上行控制信息为例，假设基站为UE配置了一个小区组集合，根据小区组索引得出的小区组的配置如表1所示。
表1
Figure PCTCN2016081555-appb-000001
Figure PCTCN2016081555-appb-000002
下面，以上行控制信息具体为CQI为例对本发明上行信息传输方法进行详细说明，具体的，可参见图3，图3为本发明上行信息传输方法实施例二 中CQI的上报过程示意图。
请参照图3，假设小区组中包括4个小区，Cell1～Cell4，图中黑色实线箭头表示Cell1的CQI上报时机，不带箭尾的空心箭头表示Cell2的CQI上报时机，带箭尾的空心箭头表示Cell3的CQI上报时机，黑色虚线箭头表示Cell4的CQI上报时机。以Cell1的CQI为例，UE根据表1所示的配置信息中的周期和偏移，找到满足“(SFN×10+子帧号)modCell1的CQI周期T1＝Cell1的CQI偏移值”的子帧，在对应的子帧，通过对应的Cell上报CQI，其中，第一次是通过Cell1自身上报，第二次是通过Cell2上报，第三次是通过Cell3上报。其他上行控制信息，如RI、PMI、HARQ、PTI等的上报，与CQI的上报机制相同。
需要说明的是，对于小区组中的Cell4，其对应的上行控制信息可以全部通过其他cell传输，而Cell4本身不传输上行控制信息。例如，当Cell4为一个只工作在下行的小区时。
本发明实施例二提供的上行信息传输方法，对于小区组中的一个具体的小区，通过将该小区的上行信息分散给该小区自身，或者其他小区，从而将整个小区组的上行信息分散到小区组中的多个小区传输，解决了PCell容量受限的问题。
实施例三
上述实施例二中，并未对第二小区为非授权频谱小区且不可用时，如何传输第一小区的上行信息进行说明。本实施例中，将详细说明当第二小区为非授权频谱小区且不可用时，如何传输第一小区的上行信息。其中，第一小区可以是授权频谱小区也可以是非授权频谱小区。
本实施例中，第二小区为非授权频谱小区；所述UE通过所述第二小区向所述基站发送所述第一小区的上行信息之前，若确定此刻所述第二小区为不可用的非授权频谱小区，则执行如下两种处理：处理一、UE不发送所述第一小区的上行信息；处理二、UE从本该发送所述第一小区的上行信息的时刻启动窗口定时器；所述UE在所述窗口定时器运行期间内检测所述第二小区是否可用，若可用，则通过所述第二小区向所述基站发送所述第一小区的上行信息；否则，不通过第一小区的上行信息。
具体的，基站为UE配置小区组时，向UE指示小区组中的各个小区类型 到底是授权频谱小区还是非授权频谱小区。UE在计算出上行信息的发送时机后，如果该上行信息在非授权频谱小区传输，则UE在传输该上行信息之前，需要先做先听后说(Listen before talk，LBT)，即监听该非授权频谱小区是否可用，若该非授权频谱小区当前被占用，则不能传输。此时，可以采用上述的处理一，即若LBT失败，则UE本次不发送上行信息；或者，采用上述的处理二，即若LBT失败，UE从本该发送上行信息的时刻开始，启动一个窗口定时器，在定时器运行期间继续对第二小区做LBT，若LBT成功，则在成功的时刻发送上行信息，若在定时器运行期间LBT始终不成功，则本次不发送上行信息。具体的，可参见图4。
图4为本发明上行信息传输方法实施例三中通过非授权频谱小区上报上行信息的示意图。
请参照图4，假定Cell2是非授权频谱小区，UE本该在T2时刻通过Cell2发送Cell1的上行信息，但是LBT失败，根据处理1，UE不在T2时刻通过Cell2发送Cell1的上行信息；根据处理二，UE在T2时刻启动一个窗口定时器，并在该窗口定时器内继续对Cell2做LBT，若LBT成功，则UE通过Cell2发送Cell1的上行信息。
需要说明的是，当采用上述处理二时，同一个非授权频谱小区内，发送不同小区的上行信息使用的窗口定时器的长度可以不同或相同，传输同一个小区的不同类型的上行信息使用的窗口定时器的长度也可以不同或相同。也就是说，从UE的角度来说，为每个UE配置的窗口定时器的长度可以不同；从小区的角度来说，为每个小区配置的窗口定时器的长度可以不同；从不同类型的上行信息来说，对每个上行信息配置的窗口定时器的长度也可以不同。
本发明实施例三提供的上行信息传输方法，当通过非授权频谱小区传输上行信息时，在检测出非授权频谱小区不可用时，停止本次传输或启动窗口定时器，在窗口定时器内检测出非授权频谱小区可用时，继续传输上行信息，提高通过非授权频谱小区传输上行信息的可靠性。
实施例四
上述实例三中，在上行信息的发送时机，当检测出第二小区为不可用的非授权频谱小区时，要么放弃传输上行信息，要么启动窗口定时器，在窗口 定时器运行期间内检测出第二小区可用时，继续通过第二小区第一小区的上行信息。该过程中，是在用同一个非授权频谱小区传输上行信息。本实施例中，第二小区为非授权频谱小区；所述UE通过所述第二小区向所述基站发送所述第一小区的上行信息之前，若确定所述第二小区为不可用的非授权频谱小区，则确定所述第二小区的至少一个备选小区中是否存在可用的备选小区；若所述UE确定出所述第二小区的至少一个备选小区中存在可用的备选小区，则通过所述第二小区的可用的备选小区向所述基站发送所述第一小区的上行信息；否则，停止通过所述第二小区向所述基站发送所述第一小区的上行信息。
具体的，对于每个非授权频谱小区，基站为该非授权频谱小区配置一个或多个备选小区，若配置了多个备选小区，则同时配置这些备选小区的顺序；或者，也可以不配置先后顺序，此时，UE自行决定顺序。若UE在传输上行信息之前，在非授权频谱小区做LBT失败，则按照顺序选择备选小区，通过备选小区传输上行信息。该过程中，若所有的备选小区都是非授权频谱小区，且当前时刻所有的备选小区都不可用，则UE启动一个窗口定时器，在窗口定时器运行期间内，同时监测这些备选小区，哪个备选小区的频谱先变为可用，则通过该备选小区传输上行信息；若窗口定时器超时，所有的备选小区都一直都处于不可用状态，则UE放弃发送本次上行信息。具体的，可参见图5。
图5为本发明上行信息传输方法实施例四中通过非授权频谱小区的备选小区上报上行信息的流程图，包括：
201、UE确定第二小区是否为可用的非授权频谱小区。
本步骤中第二小区是非授权频谱小区，UE检测上行信息发送时刻，第二小区是否可用。若可用，则执行步骤202；否则，执行步骤203。
202、UE传输第一小区的上行信息。
本步骤中，UE通过第二小区发送第一小区的上行信息。
203、UE确定第一备选小区是否可用，若可用，则执行步骤202；否则，执行步骤204；
步骤204、UE确定第二备选小区是否可用，若可用，则执行步骤202；否则，执行步骤205，依次对其他备选小区进行判断。
步骤205：UE确定第X个备选小区是否可用，若可用，则执行步骤202；否则，执行步骤206；
步骤206：启动窗口定时器。
207、在窗口定时器运行期间内判断第二小区或第二小区的备选小区中是否出现可用的小区，若出现，则执行步骤202；否则，执行步骤208；
208、UE停止传输上行信息。
需要说明的是，上述图5中步骤206与207为可选步骤。
需要说明的是，同一个非授权频谱小区内，发送不同小区的上行信息使用的备选小区可以相同或不同，传输同一个小区的不同类型的上行信息使用的备选小区也可以不同或相同。也就是说，从UE的角度来说，为每个UE配置的备选小区可以不同；从小区的角度来说，为每个小区配置的备选小区可以不同；从不同类型的上行信息来说，对每个上行信息配置的备选小区也可以不同。
另外，当UE通过备选小区传输上行信息时，该备选小区使用的时频资源位置可以与第二小区中使用的时频资源位置相同或不同。不同时，备选小区的时频资源位置可以由基站分配，也可以由UE根据第二小区中分配给自己的时频资源位置自行推算。
本发明实施例四提供的上行信息传输方法，通过为非授权频谱小区配置多个备选小区，提高上行信息传输的可靠性。
实施例五
上述实施例一至四所述的方案，除了适用于上行信息中上行控制信息的传输外，还适用于上行信息中上行数据信息的传输。下面，以图6为例对上行数据信息发送进行详细讲解。
图6为本发明上行信息传输方法中上行数据信息的发送示意图。请参照图6，假设小区组中包含四个小区Cell1～Cell4，该些小区均为非授权频谱小区，根据优先级顺序，Cell1的备选小区依次为Cell2、Cell3、Cell4；Cell2的备选小区依次为Cell3、Cell4、Cell1；Cell3的备选小区依次为Cell4、Cell1、Cell2、；Cell4的备选小区依次为Cell1、Cell2、Cell2。上行数据信息传输过程中，假设UE根据上行资源指示信息确定出目标小区为Cell1，倘若在上行传输时机Cell1不可用，则UE依次在Cell2、Cell3与Cell4上做 LBT，哪个小区可用，则就在哪个小区上传输上行数据信息。需要说明的是，图6中为突出UE顺序做LBT的行为，在时间上将各个LBT明显的错开，然而，实际上与子帧的长度相比，LBT的时间特别短。其中，备选小区的信息可以是基站通过RRC信令配置的，也可以是基站在指示上行资源的时候临时指示给UE的，本发明并不以此为限制。
上述过程中，基站为UE分配上行资源时，上行资源指示信息所指示的信息可以仅指示上行资源所在的小区、物理资源块(Physical Resource Block，PRB)所在的位置、调制与编码方式(Modulation and Coding Scheme，MCS)、是捎带CSI信息、传输功率控制(Transport Power Control，TPC)等，还可以为每个备选小区指示不同的上行资源分配参数，甚至可以预先通过高层信令配置在各个备选小区使用的上行资源分配参数，本发明实施例并不做限定。
本发明实施例五中，通过为非授权频谱小区配置多个备选小区，提高上行数据信息传输的可靠性。
实施例六
本实施例中，UE从所述小区组中确定出无线链路监测RLM组，该RLM组中的小区均为非授权频谱小区；所述UE对所述RLM小区组中的各个小区依次执行RLM；所述UE根据所述RLM，确定出所述RLM组中的各个小区均不可用；所述UE启动RLM定时器，在所述RLM定时器运行期间内检测所述RLM小区组中是否存在可用的非授权频谱小区，若存在，则停止所述RLM定时器；否则，在所述RLM定时器超时后确定所述RLM小区组中的所有非授权频谱小区发生无线链路失败RLF。其中，UE对RLM小区组中的各个小区依次执行RLM是指：UE在一个大尺度时间内，对RLM小区组中的各个小区执行RLM，但是不会同时对多个小区执行RLM
具体的，eNB为UE配置无线链路检测(Radio Link Monitor，RLM)组，并将该RLM组的配置信息发送给UE。当UE确定出RLM组后，在RLM组范围内做RLM。如果UE当前正在做RLM的小区变得不可用，UE自行选择另一个可用的小区做RLM。或者eNB配置小区优先级，如果UE当前正在做RLM的小区变得不可用，UE在当前可用的小区中选择优先级最高的一个，作为新的RLM目标。当RLM组内所有的小区都不可用，或者所有的小区信 道低于门限，UE启动RLM定时器。在RLM定时器运行期间内，只要检测出RLM组中的一个小区可用，或信道高于门限值，则UE停止运行RLM定时器。若RLM定时器超时，则UE认为发生了无线链路失败(Radio Link failure，RLF)。此时，UE通过其他小区上报RLF，或者发起无线资源控制(Radio Resource Control，RRC)重建立。具体的，可参见图7。
图7为本发明上行信息传输方法中UE使用RLM小区组监听RLM的示意图。请参照图7，RLM组内包含两个小区：非授权频谱小区1与非授权频谱小区2，UE在T1时刻检测出非授权频谱小区1与非授权频谱小区均不可用，或信道低于门限，则启动RLM定时器，在RLM定时器运行期间内继续检测非授权频谱小区1与非授权频谱小区2是否可用，若可用，则停止运行RLM定时器；否则，UE在RLM定时器超时后，即T2时刻确定出RLM小区组中的所有非授权频谱小区发生RLF。
本发明实施例六中，通过对RLM组内的多个小区的无线信号进行检测，只有在所有小区的信号均不可用时，并持续一段时长后，才认为发生了RLF，提高了RLF的判决门槛，提升了非授权频谱小区的可用性，并解决了由于非授权频谱小区不可用导致的RLM误判的问题。
实施例七
本实施例中，UE从所述小区组中确定出上行时间参考组，该上行时间参考组中的小区均为非授权频谱小区；所述UE确定所述上行时间参考组中是否存在可用的非授权频谱小区，若存在，则从可用的非授权频谱小区中选择出一个作为上行时间参考；否则，所述UE启动上行发送定时器，在所述上行发送定时器运行期间内检测所述上行时间参考组中是否存在可用的非授权频谱小区，若存在，则停止所述上行发送定时器；否则，在所述上行发送定时器超时后确定所述UE与所述基站不同步。
具体的，eNB为UE配置上行时间参考组，并将该上行时间参考组的配置信息发送给UE。当UE确定出上行时间参考组后，从该上行时间参考组内选择出一个可用的小区作为上行时间参考。若该上行时间参考组内所有的小区均不可用，则UE启动一个上行发送定时器，在上行定时器超时之前，只要上行时间参考组内的任意一个小区变为可用，则停止运行上行发送定时器，将该可以的小区作为上行时间参考小区。定时器运行期间内，若UE需 要发送上行信息，例如发送上行控制信息或上行数据信息，则以自己内部维护的时钟作为上行时间参考。若定时器超时，所有的小区均不可用，则UE认为自己内部维护的时钟与基站时钟不再同步，UE发起发送上行信息。
上述过程中，UE发送上行信息时，以上行时间参考组内的任意一个小区的下行子帧作为时间参考；如果小区组内所有的小区当前均不可用，且上行发送定时器尚未超时，则UE以自己内部维护的时钟作为上行参考时间；如果上行时间参考组内的所有小区当前均不可用，且上行发送定时器已经超时，则UE认为自己与基站不同步，放弃上行发送。具体的，可参见图8。
图8为本发明上行信息传输方法中UE使用非授权频谱小区作为上行时间参考的示意图。请参照图8，上行时间参考组内包含两个小区：非授权频谱小区1与非授权频谱小区2，T1时刻之前，上行时间参考组内存在可用的非授权频谱小区，UE发送上行信息时，选择任意一个可用的非授权频谱小区作为上行时间参考；在T1时刻，UE检测出非授权频谱小区1与非授权频谱小区均不可用，或信道低于门限，则启动上行发送定时器，在上行发送定时器运行期间内，以自己内部维护的时钟作为上行时间参考，并且，若检测出任意一个非授权频谱小区变为可用，则采用该非授权频谱小区作为上行时间参考；T2时刻，上行发送定时器超时，此时UE认为自身与基站不同步，放弃发送上行信息。
继续检测非授权频谱小区1与非授权频谱小区2是否可用，若可用，则停止运行RLM定时器；否则，UE在RLM定时器超时后，即T2时刻确定出RLM小区组中的所有非授权频谱小区发生RLF。
本实施例中，当上行时间参考组中的所有小区均不可用且定时器超时后，UE才确定自身与基站不同步，进而放弃发送上行信息，解决由于非授权频谱小区不可用导致UE发送上行时间参考的问题。
实施例八
上述实施例七中，如果上行时间参考组内的所有小区当前均不可用，且上行发送定时器超时，则UE放弃上行发送。本实施例中，上行时间参考组还包含授权频谱小区，当上行时间参考组内的所有的非授权频谱小区当前均不可用，且上行发送定时器超时，UE接收所述基站发送的时间差，所述时间差指示所述授权频谱小区与所述上行时间参考组中的各非授权频谱小区之间 的子帧边界差值；所述UE在所述上行发送定时器超时后确定所述UE与所述基站不同步，还根据所述授权频谱小区与所述时间差，确定上行发送时间参考。
具体的，eNB预先向UE通知一个时间差，该时间差表示UE所使用的授权频谱小区与非授权频谱小区的子帧边界差值。eNB可以通过RRC信令或MAC信令向UE通知该时间差，还可以定期更新该时间差，或者事件触发更新该时间差。例如，UE检测到时间差高于eNB通知的值，则通知基站，基站接收到后，向UE发送更新后的时间差值。当上行参考时间小区组内所有的非授权小区当前不可用时、且上行发送定时器超时后，UE使用授权频谱小区作为时间参考，并辅以“时间差”，作为上行发送的时间参考。具体的，可参见图9。
图9为本发明上行信息传输方法中UE通过授权频谱小区与时间差确定上行时间参考的示意图。请参照图9，T2时刻，上行参考时间小区组内所有的非授权小区当前不可用时、且上行发送定时器超时后，UE使用授权频谱小区作为时间参考，并辅以“时间差”，作为上行发送的时间参考。
本实施例中，上行时间参考组中还包括授权频谱小区，当上行时间参考组中的所有小区均不可用且定时器超时后，UE使用授权频谱小区作为时间参考，并辅以“时间差”，作为上行发送的时间参考，解决由于非授权频谱小区不可用导致UE发送上行时间参考的问题。
实施例九
本实施例中，所述UE根据SC-PTM优先级从所述小区组中确定出第三小区，所述第三小区为所述小区组中SC-PTM优先级最高的小区，或者，所述第三小区为所述小区组中SC-PTM优先级最低的小区；所述UE在一个多播控制信道MCCH周期中，通过所述第三小区接收所述基站发送的单小区多播控制信道(Single Cell-Multicast Control Channel，SC-MCCH)消息。
具体的，基站为UE配置小区组，该小区组内的所有小区的广播信息，可以由基站通过专用的信令告知给UE，也可用由基站通过广播信令告知给UE。小区组内所有小区的广播信息包括单小区点到多点(Single Cell-Point To Multipoint，SC-PTM)的传输相关参数：SC-MCCH的重复周期、偏移值、子帧号等信息，且小区内所有小区的SC-MCCH消息的内容完全相同。也就 是说，小区组内所有小区使用相同的无线帧号和子帧号，并且在相同的子帧内发送SC-MCCH消息。当然，采用非授权频谱小区发送SC-MCCH消息时，需要先获得频谱的使用权。与授权频谱小区相比，非授权频谱小区还需要将本小区在整个小区组内的SC-PTM优先级告知给UE。如此一来，如果同一时刻有多个非授权频谱小区都获得了频谱使用权，基站只通过优先级最高的那个非授权频谱小区发送SC-MCCH消息，而不是在其他的非授权频谱小区发送SC-MCCH。当然，也可以只通过优先级最低的非授权频谱小区发送SC-MCCH消息。具体的，可参见图10。
图10为本发明上行信息传输方法中SC-MCCH的发送示意图。请参照图10，小区组中包含三个非授权频谱小区，Cell1～Cell3，优先级依次降低。UE读取非授权频谱小区的***信息后，确定基站会通过小区组在哪些子帧发送SC-MCCH消息，图10中示出了两次SC-MCCH消息的发送时机，第一次，Cell1和Cell2都获得了频谱使用权，而这两个小区中，Cell1的优先级更改，因此基站通过Cell1发送SC-MCCH消息。第二次，只有Cell3获得了频谱使用权，所以基站通过Cell3发送SC-MCCH消息。当然，也有可能在SC-MCCH的发送时机，任何一个小区都没有获得频谱使用权，此时，基站不发送SC-MCCH消息。
UE在接收到基站发送的SC-MCCH后，根据所述SC-MCCH，确定所述基站发送SC-MTCH消息的SC-MTCH窗口，包括SC-MTCH窗口的起始位置和窗口长度；所述UE根据SC-PTM优先级，从所述小区组中确定出第四小区，所述第四小区为在SC-MTCH窗口对应的时间内可用的非授权频谱小区；所述UE通过所述第四小区接收所述基站在SC-MTCH窗口内发送的SC-MTCH消息。
具体的，UE对其SC-MCCH，确定出基站发送单小区多播业务信道(Multicast Traffic Channel，SC-MTCH)消息的发送时机，该发送时机可以理解为用哪个窗口、哪个无线网络临时标识(Radio Network Tempory Identity，RNTI)发送。具体的，可参见图11。
图11为本发明上行信息传输方法中SC-MTCH消息的发送示意图。请参照图11，基站在SC-MCCH中与UE协商好发送SC-MTCH消息的窗口的起始位置和窗口长度。其中，窗口的起始位置可用Scheduling Period Start Offset  SCPTM表示，窗口长度用on Duration Timer SCPTM表示。请参照图11，第一个SC-PTM周期内，Cell1和Cell2都获得了频谱使用权，基站通过SC-PTM优先级最高的Cell1发送SC-MTCH，如图中粗黑线条表示。基站发送SC-MTCH后，启动非连续周期(Discontinuous Reception，DRX)静止定时器SCPTM(DRX-Inactivity Timer SCPTM)，将发送窗口延长到T3。但是，Cell1的发送时机只能持续到T2。从T2到T3时刻，小区组中只有Cell2具有频谱使用权。此时，若基站还有SC-MTCH发送，则通过Cell2发送。到了T3时刻，DRX-Inactivity Timer SCPTM超时，窗口结束，基站停止发送SC-MTCH。
在第二个SC-PTM周期内，SC-MTCH的发送时机为T4，此时，窗口的起始位置为T4，窗口长度内，只有Cell3获得了频谱使用权，因此基站通过Cell3发送SC-MTCH。
需要说明的是，若在窗口长度内，基站没有发送SC-MTCH的需求，则等待窗口时长后，窗口结束。当然，也有可能在一个窗口长度内，任何小区都没有获得频谱使用权，此时，基站不发送SC-MTCH。
本实施例中，将多个非授权频谱小区绑定在一起，协作发送SC-MCCH或SC-MTCH，提升了发送成功率。
实施例十
本实施例中，所述UE通过所述小区组中的第五小区接收所述基站发送的下行数据，所述第五小区为非授权频谱小区；所述UE从所述小区组中确定出第六小区，所述第六小区为所述下行数据的混合自动重传请求窗口HARQ Windows时间内最早出现的、具有可用的物理上行共享信道PUCCH机会的小区；所述UE通过所述小区组向所述基站发送上行控制信息，包括：所述UE通过所述第六小区的所述PUCCH机会向所述基站发送所述下行数据的HARQ。
具体的，在小区组中的各个小区同步的情况下，基站预先为每个Cell配置上下行子帧配比，并且在一部分上行子帧中，按需要配置PUCCH，PUCCH的时频位置也可以预先配置好并通知给UE，例如图12A所示。
图12A为本发明上行信息传输方法中小区同步情况下的PUCCH。请参照图12A，一个传输机会(Transmission Opportunity，TXOP)内，Cell1每次抢到频谱，固定先发3个下行子帧(如图中斜线填充部分所示)，然后发送3 个上行子帧(如图中方格填充部分所示)。3个上行子帧中，第一个和第三个子帧中有PUCCH的时频资源，时域上都位于上行子帧的第一列符号，频域在第X个物理资源单元(Physical Resource Element，PRE)到第Y个PRE之间(如图中竖线填充部分所示)。Cell2每次抢到频谱，固定发送4个下行子帧，然后再发送2个上行子帧。2个上行子帧中，在第二个上行子帧中有PUCCH的时频资源，时域上位于第二列符号，频域位于第X个PRE和第Y个PRE。
在HARQ反馈过程中，UE从非授权频谱小区接收到下行数据，在一定的时间窗口内选择最早出现的一次PUCCH机会，传输HARQ反馈。当然，UE在传输HARQ反馈之前需要监听信道，抢占频谱使用权，若发现对应的频谱已经被占用，则不能在该PUCCH发送时机进行HARQ的反馈了。此时，UE需要选择窗口内下一次PUCCH机会，再次尝试传输HARQ反馈。请参照图12A，eNB在子帧N通过Cell1向UE发送了一个数据块(如图中横线填充部分所示)。假定UE认为HARQ窗口(HARQ Windows)从子帧N+4开始，到N+7结束。UE在该HARQ窗口内，最早出现的PUCCH资源，即N+4子帧、Cell1上的PUCCH资源发送HARQ反馈。如果UE监听信道发现该资源已经被占用，则选择N+5、Cell2上的PUCCH发送HARQ反馈。如果到了HARQ window末尾，UE依然没有抢到PUCCH使用权，则不反馈HARQ。
上述的流程是假定多个非授权频谱小区时同步的，也就是说，从UE的角度来看，多个非授权频谱小区的子帧边界是对齐的。对于非同步的场景，上述HARQ反馈流程稍稍变化。具体的，可参见图12B。
图12B为本发明上行信息传输方法中小区异步情况下的PUCCH。请参照图12B，UE在Cell1接收上行数据信息后，以Cell的子帧边界所谓计算HARQWindow的标尺，并使用这个标尺，判断Cell2上的PUCC时机是否落在HARQWindows内，若Cell2上的某个PUCCH资源所处的物理资源在时间尺度上正好跨过了HARQ window边界，如图12B中Cell2内的最后一个PUCCH资源。这种情况下，是否适用该PUCCH资源反馈HARQ，取决于eNB的配置。
需要说明的是，上述图12A与图12B中，均是假定非授权频谱小区每次抢到频谱使用权后的上下行子帧配比是预先配置好的，不会动态改变。实际上，这个上下行子帧配比也可以不预先配置，而是由eNB每次抢到信道后根 据当时的上下行数据量临时确定。只要eNB每次为TXOP确定上下行子帧配比后，通知给UE，则UE可以推算出HARQ Window内可用的PUCCH资源。
另外，还需要说明的是，上述图12A与图12B均未考虑多个Cell的PUCCH资源发生在同一个时间的情形。对于这种情形，如果UE只在一个Cell上抢占到信道使用权，则使用这一Cell的PUCCH发生HARQ；如UE同时在多个Cell上抢到信道使用权，就按照预先定义的先后顺序，选择一个Cell，使用这个Cell上的PUCCH发送HARQ。
本实施例中，UE可用从小区组中选择出一个小区发送HARQ，相较于现有技术中只能使用PCell的PUCCH发送HARQ，提升了UE反馈HARQ的概率。
实施例十一
本实施例中，所述UE通过所述小区组向所述基站发送上行控制信息之前，还确定信道状态指示CSI资源。
具体的，基站为UE配置周期性的CSI资源，只配置时间位置，不配置具体在哪个Cell。此时，有两种实现方式：方式一、所述UE接收所述基站发送的第一CSI资源指示信息，所述第一CSI资源指示信息指示所述CSI资源的时间位置；所述UE根据所述第一CSI资源指示信息，将所述小区组中每个小区的所述时间位置预留为所述CSI资源的位置。具体的，基站为每个非授权频谱小区的该时域位置都预留座位PUCCH位置，UE发送PUSCH做速率匹配(rate matching)时避开这个位置；
方式二、所述UE接收所述基站发送的第二CSI资源指示信息，所述第二CSI资源指示信息指示所述CSI资源的时间位置和第七小区；所述UE根据所述第二指示信息，将所述第七小区的所述时间位置预留为所述CSI资源的位置。具体的，在每次TXOP开始时，基站用广播方式通知PUCCH在哪个非授权频谱小区，没有PUCCH的非授权小区将相应位置用作PUSCH。
在预先配置好的周期性CSI资源位置，UE判断哪些非授权频谱小区时上行子帧，并在这些小区监听信道，抢频谱使用权。如果成功获得非授权频谱小区的使用权，且没有PUSCH发送，就利用抢到频谱的非授权频谱小区的PUCCH发送CSI等上行控制信息；若UE抢到频谱，且有PUSCH发送，则领用抢到频谱的非授权频谱小区的PUSCH发送CSI；如果UE没有抢到任何 小区的频谱使用权，就不发送SCI。
另外，上述过程也可以改为基于窗口机制的。具体的，预先为UE配置周期性的CSI，该些CSI资源是按照时间窗排列的。每个时间窗口内，可以有一个或多个用于发送周期性CSI的PUCCH资源，UE只需要发送一次周期性CSI就可以。UE按照时间先后顺序，在每次准备发送周期性CSI之前抢占频谱资源，如果抢占成功，则利用PUCCH资源发送周期性CSI；如果抢占不成功，就不发送，并且在该窗口内的下一次PUCCH资源出现前抢占频谱资源……如果知道窗口结束也没有抢到频谱资源，就不发送周期性CSI。
