Description

一种计数方法及装置 技术领域
本发明涉及通信技术领域，尤其涉及一种计数方法及装置。
背景技术
为了使终端省电，LTE系统引入了非连续接收(Discontinuous reception，DRX)技术，DRX周期包括激活期和休眠期。终端会周期性的醒来进入激活期，在激活期去监听物理下行控制信道(Physical Downlink Control Channel，PDCCH)，检测是否有下行数据或上行授权到达，在休眠期不监听PDCCH信道。
在激活期间终端会根据条件启动相应的DRX定时器，如持续时间定时器(on Duration Timer)，DRX静止定时器(drx-Inactivity Timer)，DRX重传定时器(drx-Retransmission Timer)，DRX上行重传定时器(drx-ULRetransmission Timer)，竞争解决定时器(mac-ContentionResolution Timer)等，其中，onDuration Timer，drx-Inactivity Timer，mac-Contention Resolution Timer是按照终端配置的，所有的服务小区都使用相同的定时器，而drx-Retransmission Timer，drx-ULRetransmission Timer是按服务小区的HARQ进程配置的，每一个HARQ进程维护一个相应的drx-Retransmission Timer或drx-ULRetransmission Timer。
具体的，终端在休眠期结束后启动on Duration Timer。终端在激活期间不停的监听PDCCH，如果在任意一个服务小区上终端有上行授权或下行数据到达，那么终端启动或重启drx-Inactivity Timer。否则，on Duration Timer超时后直接进入休眠期。终端在激活期间如果未成功接收下行数据，那么会在混合自动重传请求(Hybrid Automatic Repeat reQuest，HARQ)回程时间定时器(HARQ Round Timer，HARQ RTT)(如8ms)后启动或重启drx-Retransmission Timer，或启动或重启drx-ULRetransmission Timer，其中drx-Retransmission  Timer是针对下行异步HARQ重传，而drx-ULRetransmission Timer是针对上行异步HARQ重传。终端在drx-ULRetransmission Timer或drx-Retransmission Timer定时器期间等待重传数据，如果drx-Retransmission Timer或drx-ULRetransmission Timer超时，还没重传相应的数据，那么终端就可能直接进入休眠期。总之，激活期的长度取决于on Duration Timer、drx-Inactivity Timer，drx-ULRetransmission Timer和drx-Retransmission Timer等。
这些定时器计数是按PDCCH子帧(PDCCH-subframe)计数，以确定激活期的时长。所谓PDCCH-subframe就是：如果载波聚合小区都采用非时分双工(Time Division Duplexing，TDD)制式，基站在载波聚合小区中发送的所有下行子帧(subframe)则均可定义为PDCCH子帧。如果载波聚合小区采用的不全是频分双工(Frequency Division Duplexing，FDD)制式，则有两种情况：第一种全是TDD制式，另一种是部分TDD制式。在这两种情况下，如果终端在多个载波聚合小区下不能够同时接收和发送消息，则终端以特殊小区(Special Cell，SPCell)为准，如果基站在SPCell中发送的子帧是下行子帧，那么基站发送的子帧就是PDCCH子帧。其中，SPCell为主小区(Primary Cell，PCell)或辅基站的主小区(Primary Secondary Cell，PSCell)。如果终端在载波聚合小区下能够同时接收和发送消息，那么只要任意一个小区的子帧为下行子帧，此时就可确定为PDCCH子帧，不过，这种情况需要除去跨载波调度的小区的子帧。例如，PCell，SCell1，SCell2，SCell3都是终端的载波聚合的服务小区，若采用SCell2跨载波调度SCell3，那么在确定PDCCH子帧时需要除去SCell3的子帧。
另外，mac-contentionresolution Timer也是按PDCCH-subframe计数的。这个定时器适用于基于竞争的随机接入的消息，基于竞争的随机接入主要有四步：第一步，终端发送消息1，即前导序列。第二步，基站(Evolutional Node B，eNB)发送消息2，即随机接入响应消息。第三步，终端发送消息3，消息的具体内容很多，比如缓存状态报告(Buffer Status Report，BSR)、s-TMSI等。第四步，eNB发送消息4，即竞争解决消息。终端在成功发送消息3后，就 会启动mac-contentionresolution Timer，以等待消息4的下发。
LTE引入辅助授权接入(License Assisted Access，LAA)小区之后，并与授权小区载波聚合。在载波聚合小区中，所有小区都是子帧对齐的，即统一的子帧边界和子帧号。同时，3GPP规定，针对LAA小区上的数据传输，无论是eNB还是用户设备(User Equipment，UE)，它们在发送任何数据前都要先完成(Listen Before Talk，LBT)过程。如果LBT成功，信道能量检测低于一定门限，则认为信道空闲，数据可正常发送；否则，认为信道忙碌，数据不能发送。
由于非授权小区使用的是非授权频谱，而非授权频谱没有对称的上下行频谱，所以FDD帧结构不会适用于非授权小区。对于TDD模式，尽管有一定数量的上下行配比。但是还是不够灵活，不能根据上下行数据量合理的安排帧结构，从而有效的使用每一次抢占到的传输机会。eNB或终端成功抢占到信道资源的使用权称为传输机会。所以非授权小区采用的帧结构可以为灵活上下行的帧结构，在一个传输机会中，可以是全下行子帧，或者，全上行子帧，或者，部分下行传输子帧+部分上行子帧+部分特殊子帧。
在这种帧结构中，终端在计算PDCCH子帧时，需要区分当前子帧上的传输是上行传输，下行传输还是WiFI传输。但是，现有技术中，终端在区分LAA小区的子帧上的传输方向时，容易出现PDCCH子帧的误判，进一步的，由于终端的DRX定时器是根据PDCCH子帧进行计数，这样终端侧和基站侧在进行DRX定时器计数时，由于终端在LAA小区无法准确判断出子帧方向，从而导致DRX定时器在终端侧和基站侧理解不一致，继而影响数据调度。
发明内容
本发明实施例提供一种计数方法及装置，已解决现有的LAA小区的载波聚合场景下，DRX定时器在终端侧和基站侧理解不一致，影响数据调度的问题。
第一方面，提供一种计数方法，应用于第一小区与第二小区的载波聚合 场景中，包括：
终端获取所述第一小区的子帧K1以及所述第二小区的子帧K2；
所述终端在子帧K2中确定PDCCH子帧，在子帧K1和子帧K2中确定监听子帧；
所述终端基于所述PDCCH子帧，控制DRX定时器进行计数，并基于所述监听子帧监听PDCCH，以获知下行数据和/或上行授权到达；
所述第一小区为需做信道空闲检测的小区，所述第二小区为不需做信道空闲检测的小区。

具体实施方式
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。
本发明的技术方案，可以应用于长期演进(Long Term Evolution，简称LTE)系统，未来演进的4.5G或5G系统等，本发明并不限定。
首先，对本申请中的部分用语进行解释说明，以便于本领域技术人员理解。
1)、基站又可以称之为无线接入网(Radio Access Network，RAN)设备，是一种将终端接入到无线网络的设备，包括但不限于：演进型节点B(evolved Node B，eNB)、无线网络控制器(radio network controller，RNC)、节点B(Node B，NB)、基站控制器(Base Station Controller，BSC)、基站收发台(Base Transceiver Station,BTS)、家庭基站(例如，Home evolved NodeB，或Home Node B，HNB)、基带单元(BaseBand Unit，BBU)、WIFI接入点(Access Point，AP)等。
2)、终端，即UE，也可称之为移动终端(Mobile Terminal)、移动用户设备等，可以经无线接入网(例如，Radio Access Network，简称RAN)与一个或多个核心网进行通信，用户设备可以是移动终端，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，本发明并不限定。
3)、载波聚合(Carrier Aggregation，CA)。长期演进的后续演进(Long Term Evolution Advanced，LTE-A)系统为了满足单用户峰值速率和系统容量提升的要求，引入了CA技术，该技术支持多个成员载波(Component Carrier，CC)的聚合，包括在相同频带内的CC聚合，相同频带内相邻或不相邻的CC聚合，以及不同频带内的CC聚合。终端根据自己的能力大小决定最多可以同 时利用几个载波进行上下行传输。
4)、主小区(PCell)和辅小区(SCell)。在聚合的多个成员载波中，包括一个主成员载波(Primary Component Carrier，PCC)和至少一个辅成员载波(Secondary Component Carrier，SCC)，其中，这些成员载波都属于同一个基站，PCC用于控制面的传输，也可以用于用户面的传输；SCC用于用户面的传输。PCC对应的小区为PCell，SCC对应的小区为SCell。PCell是终端初始接入的小区，负责与终端之间的无线资源控制(radio resource control，RRC)通信。SCell是在RRC重配置时添加的，用于提供额外的无线资源。PCell是在连接建立(connection establishment)时确定的；SCell是在初始安全激活流程(initial security activation procedure)之后，通过RRC连接重配置消息(RRC Connection Reconfiguration)添加/修改/释放的。
5)、“多个”是指两个或两个以上。“和/或”，描述关联对象的关联关系，表示可以存在三种关系，例如，A和/或B，可以表示：单独存在A，同时存在A和B，单独存在B这三种情况。字符“/”一般表示前后关联对象是一种“或”的关系。
本发明实施例以LTE通信系统为例，但不限于此。如图2所示，在LTE通信系统的架构示意图中，无线通信网络100可以包括至少一个基站110和核心网设备130，用以支撑终端120进行通信。例如，基站110可以是LTE中的演进型基站(evolved NodeB，eNB)，该基站110可以支持或管理至少一个授权小区和/或至少一个LAA小区。采用双连接(Dual Connectivity，DC)模式的终端120需要和网络通信时，可以同时从至少两个基站110接收数据，即至少两个基站110为终端120提供服务。其中，基站110可以实现主基站和/或辅基站的功能。核心网设备130可以包括移动性管理实体(Mobile Management Entity，MME)。
本发明实施例，涉及的场景为LAA小区与授权小区的载波聚合下，提供DRX定时器的计数方案。具体的，本发明实施例适用的LAA小区与授权小区的载波聚合主要包括以下场景：
场景一：TDD cell+LAA cell，即TDD小区与LAA小区的载波聚合，其中TDD小区作为主小区。
场景二：FDD cell+TDD cell+LAA cell，即TDD小区、FDD小区与LAA小区的载波聚合，这种场景下包括包括两种情形，第一种情形下FDD小区作为主小区，TDD小区与LAA小区作为辅小区；第二种情形下TDD小区作为主小区，FDD小区与LAA小区作为辅小区。
场景三：TDD cell+TDD cell+LAA cell，即TDD小区、TDD小区与LAA小区的载波聚合，这种场景下TDD小区可以采用相同的上下行配比模式，也可以采用不同的上下行配比模式，其中的一个TDD小区作为主小区，其余的TDD小区和LAA小区作为辅小区。
场景四：eIMTA TDD cell+LAA cell，即eIMTA TDD小区与LAA小区的载波聚合，eIMTA TDD小区作为主小区，LAA小区作为辅小区。其中，eIMTA TDD是指动态TDD上下行配比，对于支持eIMTA的UE，eNB通知多套TDD上下行配比，具体使用那一套取决于eNB的指示，这样就可以较为灵活的适应上下行数据流量。
场景五：LAA Cell+LAA cell(s)，即多个LAA小区的载波聚合，其中一个LAA小区作为主小区，其余的LAA小区作为辅小区。
针对上述场景本发明实施例提供一种计数方法及装置，已解决现有的LAA小区的载波聚合场景下，DRX定时器在终端侧和基站侧理解不一致，影响数据调度的问题。其中，方法和装置是基于同一发明构思的，由于方法及装置解决问题的原理相似，因此装置与方法的实施可以相互参见，重复之处不再赘述。
请参考图3，其为本发明实施例提供的一种计数方法的流程图，该方法应用于第一小区与第二小区的载波聚合场景中，可选的，第一小区为上述场景中的LAA小区，第二小区为上述场景中的授权小区，如TDD小区和/或FDD小区。如图3所示，该方法包括如下步骤：
步骤30：终端获取第一小区的子帧K1以及第二小区的子帧K2。
其中，所述第一小区为需做信道空闲检测的小区，所述第二小区为不需做信道空闲检测的小区。
具体的，基站在所述子帧K1中可以发送下行传输，或分配上行传输资源以便终端进行上行传输，或不发送任何传输。
需要说明的是，在具体实施时，第一小区的数量可以为1个或者多个，同理第二小区的数量也可以为1个或多个。若所述第一小区的数量为多个时，那么所述子帧K1为多个小区的子帧的集合。若所述第二小区的数量为多个时，那么所述子帧K2为多个小区的子帧的集合。
步骤31：终端在子帧K2中确定PDCCH子帧，在子帧K1和子帧K2中确定监听子帧。
具体的，所述终端确定所述子帧K2中包含至少一个特殊子帧和/或下行子帧就认为是一个PDCCH子帧。
其中，所述特殊子帧包括通过时分方式进行上行传输和/或下行传输的子帧。所述子帧包含两个维度信息：时域维度(比如子帧标准时长为1毫秒，ms)和频域维度(比如一定带宽大小的频谱资源)。所述PDCCH子帧是从时域维度描述，频域维度可以不做限制。
具体的，所述终端确定所述子帧K1和所述子帧K2中为非上行子帧的子帧为监听子帧。其中，非上行子帧为下行子帧或特殊子帧。具体的，子帧K1中所有的子帧都是下行子帧或所有的子帧都是特殊子帧或所有的子帧中存在部分下行子帧或所有的子帧中存在部分特殊子帧时，终端始终确定为一个第一小区的监听子帧，该第一小区的监听子帧为子帧K1中所有的子帧包含下行子帧或特殊子帧的子帧的集合；同理，子帧K2中所有的子帧都是下行子帧或所有的子帧都是特殊子帧或所有的子帧中存在部分下行子帧或所有的子帧中存在部分特殊子帧时，终端始终确定为一个第二小区的监听子帧，该第二小区的监听子帧为子帧K2中所有的子帧包含下行子帧或特殊子帧的子帧的集合。监听子帧包括第一小区的监听子帧和第二小区的监听子帧。
可选的，终端可通过检测第一小区的参考信号和/或下行控制信息获知当 前第一小区的子帧为非上行子帧，以及，根据事先协议约定的子帧类型的规则，如FDD或TDD，获知当前第二小区的子帧为非上行子帧。下行控制信息可用于指示终端特殊子帧的时域位置。
一种可能的实施方式中，所述终端在子帧K1和子帧K2中确定PDCCH子帧，具体可以通过以下两种实施方式。
第一种实施方式，所述终端在子帧K1和子帧K2中确定PDCCH子帧时，若所述K1子帧中包含有上行传输，或下行传输，或其他任何非长期演进(Long Term Evolution，LTE)/长期演进技术升级版(Long Term Evolution-Advanced，LTE-A)/长期演进技术升级版的升级版(Long Term Evolution-Advanced Pro，LTE-Ap)的不同空口技术的传输，比如Wi-Fi传输，以及所述K2子帧中包含上行传输和/或下行传输，终端始终确定为一个PDCCH子帧。
第二种实施方式，所述终端在子帧K1和子帧K2中确定PDCCH子帧时，所述终端确定所述K1子帧中包含有下行传输，和/或，所述终端确定所述K2子帧中包含有下行传输，终端始终确定为一个PDCCH子帧。可选的，所述终端可通过检测第一小区的参考信号和/或下行控制信息获知当前第一小区的子帧包含有下行传输。
步骤32：终端基于所述PDCCH子帧，控制DRX定时器进行计数，并基于所述监听子帧监听PDCCH，以获知下行数据和/或上行授权到达。
具体的，终端在所述监听子帧监听PDCCH，包括终端在子帧K1和子帧K2中所有的子帧包含非上行子帧的子帧监听PDCCH。
需要说明的是，所述DRX定时器为持续时间定时器或DRX静止定时器或DRX重传定时器或DRX上行重传定时器或竞争解决定时器。
下面以上述场景一的实施场景为例，来详细说明图3中的计数方法。
如图4所示，TDD小区与LAA小区的载波聚合下，PCell为上下行配比模式为2的TDD小区，SCell小区为LAA小区，使用的帧结构为灵活的帧结构。此时，第一小区为TDD小区，第二小区为LAA小区。
终端在子帧n+2时醒来进入激活期，开启on Duration Timer并监听LAA 小区的PDCCH，通过监听获知下行控制信息的指示信息为子帧n+4到子帧n+9为上行子帧。终端将TDD小区中的子帧为下行子帧或特殊子帧的子帧确定为PDCCH子帧，即子帧n+5、子帧n+6、子帧n+10、子帧n+11为PDCCH子帧，在PDCCH子帧上针对on Duration Timer计数；将LAA小区和TDD小区中的子帧为非上行子帧的子帧确定为监听子帧，由于终端没有接收到上行授权指示LAA小区中的子帧n+10、子帧n+11、子帧n+12、子帧n+13、子帧n+14为上行子帧的指示信息，因此在子帧n+2、子帧n+3、子帧n+5、子帧n+6、子帧n+10、子帧n+11、子帧n+12、子帧n+13、子帧n+14确定监听子帧，具体的，在在子帧n+2、子帧n+3、子帧n+5、子帧n+6、子帧n+10、子帧n+11、子帧n+12、子帧n+13、子帧n+14中检测LAA小区的小区参考信号获知LAA小区的监听子帧，TDD小区的监听子帧是根据上下行配比模式中的TDD小区的下行子帧，在所述监听子帧上监听TDD小区和LAA小区的PDCCH，已获知下行数据和/或上行授权的到达。
因此，终端子帧n+2不做on Duration Timer计数，但是需要监听LAA小区的PDCCH，同理，在子帧n+3也不做on Duration Timer计数，但是需要监听LAA小区的PDCCH，在子帧n+4既不用监听TDD小区和LAA小区的PDCCH，也不计数on Duration Timer。同理，在子帧n+7到子帧n+9，终端既不用监听TDD小区和LAA小区的PDCCH，也不计数on Duration Timer。在子帧n+5和子帧n+6，由于PCell都有下行传输，所以需要计数on Duration Timer，并需要监听TDD小区的PDCCH。对于子帧n+10和n+11，由于PCell都有下行传输，所以需要计数on Duration Timer，终端根据没检测出LAA小区的参考信号和下行控制信息的指示信息，获知当前子帧的传输为Wi-Fi传输，所以只需要监听TDD小区的PDCCH。对于子帧n+12到子帧n+14,由于PCell都没有下行传输，所以不需要计数on Duration Timer，而且在子帧n+12，终端不能检测小区参考信号，所以不用监听LAA小区的PDCCH，以及不用监听TDD小区的PDCCH。在子帧n+13到子帧n+14，终端根据LAA小区的小区参考信号获知当前子帧为LAA小区的下行子帧，所以监听LAA小区的 PDCCH，但是不用监听TDD小区的PDCCH。
同理，对于其他DRX定时器，如drx-Inactivity Timer，drx-Retransmission Timer，drx-ULRetransmission Timer，mac-contentionresolution Timer，具体的计数规则和监听PDCCH规则跟上面一样。
以drx-Inactivity Timer为例，如图5所示，同样终端在子帧n+2的时候醒来，进入激活期，启动on Duration Timer，计数规则如上分析。在子帧n+5时候，有下行数据到达，此时启动drx-Inactivity Timer，延长DRX激活时间，具体的计数规则和监听PDCCH规则，如同on Duration Timer。即在PDCCH子帧上计数，在监听子帧上监听TDD小区和LAA小区的PDCCH，以获知下行数据和/或上行授权的到达。
以drx-Retransmission Timer为例，如图6所示，同样终端在子帧n+2的时候醒来，进入激活期，启动on Duration Timer，计数规则如上分析。在子帧n+5接收到下行数据，但是终端没有成功解码出数据。此时终端在之后的某一个子帧启动drx-Retransmission Timer定时器，以等待重传数据，延长激活时间。具体的计数规则和监听PDCCH规则，如同on Duration Timer。即在PDCCH子帧上计数，在监听子帧上监听TDD小区和LAA小区的PDCCH，以获知下行数据和/或上行授权的到达。
综上所述，上述实施例中，终端在不需做信道空闲检测的小区即授权小区的子帧中确定PDCCH子帧，基于PDCCH子帧控制DRX定时器的计数，在需要做信道空闲检测的小区即LAA小区和不需做信道空闲检测的小区即授权小区的子帧中确定监听子帧，在监听子帧上监听PDCCH，这样在LAA小区的载波聚合下，DRX定时器计数时在终端侧能够准确确定出用于计数的PDCCH子帧，以实现高效的调度。
请参考图7，其为本发明实施例提供的另一种计数方法的流程图，该方法包括如下步骤：
步骤71：基站向终端发送配置信息，所述配置信息包括DRX定时器的至少一个时长信息。
其中，所述DRX定时器为持续时间定时器或DRX静止定时器或DRX重传定时器或DRX上行重传定时器或竞争解决定时器。
可选的，所述基站通过无线资源控制消息向所述终端发送所述配置消息，所述配置信息包括DRX定时器的至少一个时长信息。
例如，基站将包括DRX定时器的至少一个时长信息的配置信息携带在RRC链接重配置消息中发送至终端。
步骤72：所述基站向所述终端发送指示信息，所述指示信息用于指示终端从所述配置信息中的至少一个时长信息中选择一个时长信息作为所述DRX定时器的时长。
可选的，所述基站通过物理层指示消息或媒体接入控制消息向所述终端发送所述指示消息。
具体的，基站在发送指示消息时，可以采用直接信令指示，也可以采用间接信令指示。
例如，基站为on Duration Timer提前配置三个时长，分别是T1、T2和T3，基站根据当前信道的忙碌情况实时选择时长T2作为on Duration Timer的时长，通过物理层指示消息通知终端使用的on Duration Timer的时长为T2。
又例如，基站为on Duration Timer提前配置三个时长，分别是T1、T2和T3，基站将on Duration Timer的时长与传输时间间隔(Transmission Time Interval，TTI)的映射关系发送至终端，假设on Duration Timer的时长与TTI的映射关系为子帧号除3余1的对应于T1，子帧号除3余2的对应于T2，子帧号能够整除3的对应于T3，终端可以根据当前的帧号和/或子帧号推断出使用哪一个on Duration Time的时长。比如：子帧1对应于T1，子帧2对应于T2，子帧3对应于T3。因此，终端根据子帧上接收到的PDCCH指示下行传输，确定当前DRX定时器的时长。根据终端对下行传输的反馈，从而基站确定终端当前具体使用哪一个时长。
步骤73：所述终端基于所述指示信息确定所述DRX定时器的时长；
步骤74：所述终端基于所述DRX定时器的时长和预设的所述DRX定时 器的计数规则，针对所述DRX定时器进行计数。
具体的，所述DRX定时器的计数规则由基站和终端事先协商确定，遵循统一的计数规则，从而避免DRX定时器在计数时在终端侧和基站侧理解不一致，影响数据调度。
其中，所述DRX定时器为持续时间定时器或DRX静止定时器或DRX重传定时器或DRX上行重传定时器或竞争解决定时器。
综上所述，上述实施例中，基站向终端发送配置信息，预先为DRX定时器配置至少一个备选的时长信息，并通过向终端发送指示信息，从而指示终端从所述配置信息中的至少一个时长信息中选择一个时长信息作为所述DRX定时器的时长，终端基于DRX定时器的时长和预设的所述DRX定时器的计数规则，针对所述DRX定时器进行计数，这样，由于终端利用基站为终端预先配置的DRX定时器的时长，采用统一的DRX定时器计数规则，避免DRX定时器在终端和基站理解不一致而影响数据调度。

其中，所述特殊子帧包括通过时分方式进行上行传输和/或下行传输的子帧。

可选的，所述DRX定时器为持续时间定时器或DRX静止定时器或DRX重传定时器或竞争解决定时器。
本发明实施例上述涉及的装置800，可以是独立的部件，也可以是集成于其他部件中，例如本发明实施例提供的上述装置800可以是现有通信网络中的终端，也可以是集成于终端内的部件。
需要说明的是，本发明实施例中的装置800的各个单元的功能实现以及交互方式可以进一步参照相关方法实施例的描述，在此不再赘述。
