Description

一种下行控制信道增强方法及相关设备 技术领域
本发明涉及通信技术领域, 尤其涉及一种下行控制信道增强方法及相关 设备。 背景技术
非连续发送 ( Discontinuous Transmission, DTX )是永久包在线( Continuous Packet Connection, CPC ) 的特征之一, 即在没有数据传输时, 停止发送上行 专用物理控制信道 ( Dedicated Physical Control Channel, DPCCH )信令, 以 降低对网络侧设备的上行干扰, 在用户设备(UE ) 的非连续发送周期内, 为 了保持功率控制和链路同步, UE可定期发送 DPCCH脉冲信号。
双载波高速上行分组接入 ( Dual Cell High Speed Uplink Packet Access, DC-HSUPA ) 支持 UE在上行两个载波发送数据。 当 UE配置了 DTX且配置 了 DC-HSUPA时, 主、 辅载频共用一套 DTX参数, 且主、 辅载频的 DTX状 态是耦合的。
为了使得辅载频上行能够支持高速的数据传输, Rell2中引入了 DTX增 强技术, 将主、 辅载频的 DTX 参数解耦, 即辅载频有一套独立于主载频的 DTX参数, 使得辅载频能支持更长的 DTX周期。
DTX增强技术中,若辅载频釆用更长的 DTX周期,会影响辅载频的上行 DPCCH信号的发送, 进而影响辅载频下行功控性能以及辅载频的下行控制信 道的性能, 例如下行控制信道 F-DPCH、 E-RGCH、 E- AGCH和 E-HICH的性 能, 进而对辅载频的上行性能造成一定的影响。 为解决该问题, 提出了下行 控制信道增强技术。
所谓下行控制信道增强是将辅载频的 F-DPCH、 E-RGCH、 E-AGCH、 E-HICH等下行控制信道移动到主载频, 这将会占用主载频的 OVSF码资源, 导致主载频的 OVSF码资源紧张。 并且在软切换过程中, 由于 DC-HSUPA中 UE在主、 辅载频上独立维护激活集, 可能导致某些小区在辅载频上被加入到 激活集, 但主载频上未被加入激活集, 从而导致下行控制信道的跨载频配置 不成功。
类似的, 下行控制增强也可能将主载频的 F-DPCH、 E-RGCH、 E-AGCH、 E-HICH等下行控制移动到辅载频; 或者将辅载频 1上的 F-DPCH、 E-RGCH、 E-AGCH、 E-HICH等下行控制移动到辅载频 2。 该操作也可能存在上述码资 源紧张及跨载频配置不成功的问题。
可见, 现有的下行控制信道增强技术, 需要解决码资源不足以及软切换 中的下行控制信道跨载频配置不成功的问题。 发明内容

为了使本发明的目的、 技术方案和优点更加清楚, 下面将结合附图对本 发明作进一步地详细描述, 显然, 所描述的实施例仅仅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它实施例, 都属于本发明保护的 范围。
以下各实施例中, 以上行多载频为例, 上行多载频是指上行至少存在 2 个及以上的载频。
所述下行控制信道增强是指将载频 1 ( F1 )的部分或全部下行控制信道移 动到另一载频 2 ( F2 ), 例如, 载频 1为辅载频, 载频 2为主载频; 或, 载频 1为主载频, 载频 2为辅载频; 或, 载频 1和 2均为辅载频。 例如, 在传统的 DC-HSUPA技术中, 载频 F1上的 F-DPCH, E-AGCH, E-RGCH, E-HICH在 载频 F1上发, 占用的是载频 F1的码资源; 载频 F2上的下行控制信道(例如 F-DPCH, E-AGCH, E-RGCH, E-HICH等等)在载频 F2上发, 占用载频 F2 的码资源。 引入 DTX增强后, 载频 F2上的 F-DPCH, E-AGCH, E-RGCH, E-HICH等下行控制信道可能存在性能问题, 而载频 F1上的控制信道性能较 好,因此网络侧配置时,将给载频 F2的 F-DPCH, E-AGCH, E-RGCH, E-HICH 等移动到载频 F1上, 以保证原本应在 F2上的控制信道的性能, 该控制信道 的移动会占用载频 F1的码资源, 称为下行控制信道增强。 以下各实施例中, 下行控制信道增强是指将辅载频的部分或全部下行控 制信道移动到主载频, 或者, 将主载频的部分或全部下行控制信道移动到辅 载频, 或者, 将第一辅载频的部分或全部下行控制信道移动到第二辅载频。

基于与第七、 第八实施例相同的发明构思, 本发明第九实施例中, 如图 12所示, UE进行下行控制信道增强的详细方法流程如下。
步骤 1201 : UE接收下行控制信道增强的指示消息。
具体地, UE接收网络侧发送的指示消息, 该指示消息用于指示该 UE启 动下行控制信道增强。
步骤 1202: UE确定下行控制信道增强在第一载频上的生效小区, 以及确 定第二载频上与该生效小区存在协作关系的目标小区。
UE根据下行控制信道增强的不同, 确定生效小区的具体方式不同, 具体 ^口下。
若下行控制信道增强为将辅载频的部分或全部下行控制信道移动到主载 的组合, 其中, 在辅载频激活集内的小区 A1 与主载频的小区 B1 之间存在 DC-HSUPA或上行多载频的协作关系时,将主载频的小区 B1称为辅载频的小 区 A1的对应小区, 所述确定生效小区的方式: a、 将与主载频有对应小区的辅载频激活集内的小区确定为生效小区。 b、 将辅载频激活集内的服务小区确定为生效小区, 进一步, 在辅载频激 活集内除服务小区外的其它小区在主载频有对应小区时, 将该辅载频激活集 内的其它小区也确定为生效小区, 所述其它小区可以为至少一个或辅载频激 活集内除服务小区外的所有小区。
c、 在辅载频激活集内所有小区均在主载频有对应小区时, 将该辅载频激 活集内的所有小区确定为生效小区。
若下行控制信道增强为将主载频的部分或全部下行控制信道移动到辅载 频, 则确定生效小区的方式包括但不限于以下列举的具体实现方式的任意一 种或一种以上的组合, 其中, 在主载频激活集内的小区 C1 与辅载频的小区 D1之间存在 DC-HSUPA或上行多载频的协作关系时,将辅载频的小区 D1称 为主载频的小区 C1的对应小区, 所述确定生效小区的方式:
a、 将与辅载频有对应小区的主载频激活集内的小区确定为生效小区。 b、 将主载频激活集内的服务小区确定为生效小区, 进一步, 在主载频激 活集内除服务小区外的其它小区在辅载频有对应小区时, 将该主载频激活集 内的其它小区也确定为生效小区, 所述其它小区可以为至少一个或主载频激 活集内除服务小区外的所有小区。
c、 在主载频激活集内所有小区均在辅载频有对应小区时, 将该主载频激 活集内的所有小区确定为生效小区。
若下行控制信道增强为将第一辅载频的部分或全部下行控制信道移动到 第二辅载频, 则确定生效小区的方式包括但不限于以下列举的具体实现方式 中的任意一种或一种以上的组合, 其中, 在第一辅载频激活集内的小区 E1与 第二辅载频的小区 F1之间存在上行多载频协作关系时,将第二载频的小区 F1 称为第一辅载频的小区 E1的对应小区, 所述确定生效小区的方式:
a、 将与第二辅载频有对应小区的第一辅载频激活集内的小区确定为生效 小区。
b、 将第一辅载频激活集内的服务小区确定为生效小区, 进一步, 在第一 辅载频激活集内除服务小区外的其它小区在第二载频有对应小区时, 将该第 一辅载频激活集内的其它小区也确定为生效小区, 所述其它小区可以为至少 一个或第一辅载频激活集内除服务小区外的所有小区。
C、 在第一辅载频激活集内所有小区均在第二辅载频有对应小区时, 将该 第一辅载频激活集内的所有小区确定为生效小区。
釆用以上任一方式确定生效小区后, 确定在不同于该生效小区所在载频 的另一载频上、 与该生效小区存在协作关系的对应小区, 将该对应小区确定 为该生效小区对应的目标小区。
步骤 1203: UE到目标小区接收该生效小区的下行控制信道。
优选地,移动的下行控制信道包括 F-DPCH、 E-RGCH、 E-AGCH、 E-HICH 和 HS-SCCH中的任意一种或一种以上的组合。
具体实施中,若步骤 1202中确定不存在生效小区,则不再执行后续步骤, 不启动下行控制信道增强过程。
该实施例中, UE根据预定义的规则确定下行控制信道增强的生效小区以 及该生效小区对应的目标小区, 到目标小区接收生效小区的下行控制信道, 可以保证下行控制信道跨载频配置的成功率。
