本发明有益效果如下:
由于多栽波的引入, UE需要同时工作在多个载波上, 而这也使得 UE的 电量消耗极度增加, 并且, 当 UE的工作 CC处于失步状态, 则表征 UE当前 需要传输的数据较少, 当出现该情况时,如果 UE继续处于监听并收发准备的 状态, 那么对 UE来说就处于比较费电的状态。 因此, 本发明实施例提供的技 术方案中, 在 CC处于失步状态时, 便去激活处于失步状态的 CC。 由于能够 将不同步的 CC去激活, 从而也达到让 UE更加省电, 延长电池寿命的目的。 附图说明

图 2为本发明实施例中上行同步处理方法实施流程示意图;
图 3为本发明实施例中网络侧设备结构示意图;
图 4为本发明实施例中用户设备一结构示意图;
图 5为本发明实施例中用户设备二结构示意图。 具体实施方式
在 LTE-A ( Long Term Evolution-Advance, 长期演进升级) 系统中, 为了 支持更高的峰值速率, 引入了 CA ( Carrier Aggregation, 载波聚合)技术。 发 明人在发明过程中注意到: 由于多载波的引入, UE需要同时工作在多个载波 上, 而这也使得 UE的电量消耗极度增加,基于此, 本发明实施例中将提供在 多栽波系统中使 UE省电的技术方案。下面结合附图对本发明的具体实施方式 进行说明。 首先对本发明实施过程中涉及的技术特征进行说明。
一、 载波聚合技术介绍。
LTE-A的峰值速率比 LTE ( Long Term Evolution, 长期演进)有很大的提 高, 要求下行速率达到 lGbps, 上行速率达到 500Mbps. 同时, LTE-A系统 要求和 LTE系统有很好的兼容性。 基于提高峰值速率、 与 LTE系统兼容以及 充分利用频谱资源的需要, LTE-A系统引入了栽波聚合技术。
载波聚合技术是指在一个小区内上下行各包含多个 CC ( component carrier, 成员栽波), 而不是 LTE及之前的无线通信系统中只有一套栽波的模 式。 在栽波聚合系统中各个成员栽波可以是连续或非连续的, 为了和 LTE系 统兼容, 每个成员栽波的最大带宽为 20MHz, 各成员栽波间的带宽可以相同 或不同。
二、 下面对 LTE中上行同步的维护过程进行说明。
上行同步过程用于保持终端和基站的上行同步, 便于终端进行上行数据 传输和对下行数据发送 HARQ ( Hybrid Automatic Repeat Request,混合自动重 复请求)反馈信息。
图 1为上行同步维持过程示意图, 在 LTE系统中规定由基站维护上行同 步。 UE随机接入时,基站根据 preamble (前导序列)获得最初的定时提前量, 后续上行同步维护过程如图 1所示:基站和 UE分别维护一个 TAT ( TA timer, TA定时器; TA: Timing Advance,时间提前量),基站向终端发送 TA command (时间提前量调整命令)并启动 TAT, 如果终端不能正确接收 TA command, 则基站过一段时间 T1重新发送 TA command并重启 TAT,终端正确接收到 TA command则启动终端的 TAT并向基站发送 ACK (确认)信息, 基站接收到终 端发的 ACK信息之后重启基站的 TAT。 基站针对某个 UE的 TAT没有超时, 则基站认为该 UE处于同步状态; 只要 UE自己维护的 TAT没超时, 则 UE也 认为自己是同步的。
若 TAT超时, 则 UE和基站会自动释放 UE在 CC上的 SRS ( Sounding Reference signals >信道探测参考信号 )和 D-SR ( Dedicated scheduling request, 专用的调度请求) 配置, 并清空当前的半持续调度的上行和下行资源配置, 进入失步状态
三、 CC激活与去激活的说明。
在 LTE-A协议讨论中涉及到了 CC激活与去激活的过程, 即在 eNB (演 进基站)为 UE配置了工作 CC集合之后, 由于业务传输期间的数据量会产生 变化, 因此可能只需要使用几个工作栽波用于数据传输和调度即可。 在这种 情况下, 网络展可以通过去激活的过程将部分不需要的工作栽波去激活。 发 明人在发明过程中注意到的是: 将部分 CC去激活可以让 UE更加省电, 延长 电池寿命。 当 UE所需要传输的数据量增多, 即所需数据传输的 CC增多, 则 可以通过信令控制的方式将部分 CC激活。
eNB只会调度 UE处于激活状态的 CC, 不会在去激活的 CC上进行调度 和数据传输, 但是如果需要的话, 在去激活的 CC上 UE也会继续进行相应的 栽波测量和系统信息监听。
四、 special cell (特殊小区) 的说明,
在 LTE-A引入栽波技术后, 由于 UE可以同时工作在多个 CC上, 若这 些 CC均为网络侧按照小区管理的 CC, 那么从网络侧可以看到 UE在多个小 区上的情况发生。 但由于 UE 连接过程中加密使用的密钥以及 NAS ( Non Access Stratum, 非接入层)移动性管理的需要, 都需要联系到 UE的某个指 定小区上, 故该小区则称之为 special ceU。
发明人注意到, 目前 LTE-A协议中尚无明确描述多栽波系统上行失败后 的处理机制。 同时, 在移动通信系统中由于多栽波的引入, 当 UE的工作 CC 处于失步状态, 则表征 UE当前需要传输的数据较少, 当出现该情况时, 如果 UE继续处于监听并收发准备的状态,那么对 UE来说就处于比较费电的状态。
鉴于此, 针对多载波系统中聚合的各个 UL (上行) CC的同步过程的维 护方式可能不同的情况,本发明实施例中将给出一种 UE在失步状态下省电的 方法, 即当 UE处于失步状态下的 CC默认进入去激活状态(深度睡眠状态), 当该 CC再次进入同步状态则进入激活状态重新工作的方法, 下面进行说明。 图 1为上行同步处理方法实施流程示意图, 如图所示, 在上行同步处理 过程中可以包括如下步骤:
步骤 201、 确定 UE上的 CC的同步与失步状态;
步骤 202、 在 CC处于失步状态时, 去激活处于失步状态的 CC。
进一步的, 考虑到后续的激活过程, 还可以在去激活处于失步状态的 CC 后, 进一步包括:
步骤 203、 在去激活的 CC上发起随机接入过程, 或激活去激活的 CC。 下面对各步骤的具体实施方式进行说明。
在步骤 201的实施中,确定 UE上的 CC的同步与失步状态的具体实施方 式可以参考前面 LTE中上行同步的维护过程中的说明, 此处不再赘述。
由上述过程也可以看出, 网络侧与 UE均能够获知 UE上的 CC的同步与 失步状态, 因此, 步骤 202中去激活处于失步状态的 CC时, 既可以由网络侧 指示 UE去激活处于失步状态的 CC;也可以由 UE去激活处于失步状态的 CC。
在步骤 202的实施中,去激活处于失步状态的 CC的具体实施方式可以参 考前面 CC激活与去激活的说明, 此处不再赘述, 同时, 由于能够及时地将不 同步的 CC去激活,从而也达到让 UE更加省电,延长电池寿命的目的。并且, 当 UE所需要传输的数据量增多, 即所需数据传输的 CC增多时, 则可以在步 骤 203通过信令控制的方式将部分 CC激活, 级别的, TA组级别的和 CC级别的三种情况, UE的失步 CC进入去激活状态 的方式将分别以网络侧的实施为例进行说明。 同时, 还可以进一步考虑用于 维持与 special cell联系的 CC即主小区 Primary Cell所属的 CC的情况, 在对 CC级别、 TA组级别、 UE级别的 CC去激活时, 还可以进一步包括: 确定处 于失步状态的 CC是不是用于维持与 special cell联系的 CC; 确定是用于维持 与 special cell联系的 CC时, 网络侧在维持该 CC的激活状态后去激活处于失 步状态的 CC。 具体实施中, UE主动去激活的实施与之相似, 参考实施即可。 则, 对 CC级别、 TA組级别、 UE级别的 CC去激活时可以如下: 1、 UE按照 CC级别来维护各个 CC的同步失步状态。
在处于失步状态的 CC是单独的 CC时, 网络侧去激活该处于失步状态的
CC;
该方式下, 当某个 CC进入失步状态, 则网络侧释放该 CC上的 SRS和 D-SR等资源, 同时去激活该 CC, 即该 CC的相关处理单元便可以进入省电 模式; 若该 CC为用于维持基本连接的 CC, 即, 与 special cell联系的 CC, 则该 CC除外, 不用去激活。
2、 UE按照 TA组級别来维护各个 CC的同失步状态。
在处于失步状态的 CC是一个 TA組的 CC时, 网络侧去激活该处于失步 状态的 CC所属 TA組的 CC;
该方式下, 当某个 TA組进入失步状态, 则网络侧释放该 TA组内所有 CC的 SRS和 D-SR等资源, 同时去激活 TA組内所有 CC,使得该组 CC的相 关处理单元进入省电模式; 若 TA组中包括用于维持基本连接的 CC , 即, 与 special cell联系的 CC, 则该 CC除外, 不用去激活。
3、 UE按照 UE级别来维护各个 CC的同失步状态。
在处于失步状态的 CC是 UE的所有 CC时, 网络侧去激活该 UE所有的 cc。
该方式下, 当 UE进入失步状态, 则网络侧释放该 UE在所有 CC的 SRS 和 D-SR等资源, 同时去激活除 special cell之外的所有 CC, 使得这些 CC的 相关处理单元进入省电模式; 用于维持与 special cell联系的基本连接的 CC, 不用去激活。
下面对恢复 CC的激活进行说明。
在步骤 203的实施中,在去激活处于失步状态的 CC后,可以在去激活的 CC上发起随机接入过程, 或者直接激活去激活的 CC。
激活的实施同样可以由网络侧发起指示,也可以由 UE自行主动发起。具 体实施中, 可以包括:
网络侧通过激活的 CC通知 UE在去激活的 CC上发起随机接入过程; 或, 网络侧指示 UE激活去激活的 CC;
或, UE在去激活的 CC上发起随机接入过程;
或, UE激活去激活的 CC。
实施中,凡是能够实现激活 CC的技术手段都可以采用, 下面以网络侧为 例对发起随机接入过程进行说明。
网络侧可以通过 PDCCH order( PDCCH命令; PDCCH: physical downlink control channel, 物理下行控制信道)、 MAC ( Medium Access Control, 媒体接 入控制) CE ( control element, 控制单元)、 RRC ( Radio Resource Control, 无 线资源控制)信令之一或者其組合通过激活的 CC通知 UE在去激活的 CC上 发起随机接入过程。 此时, 网络侧可以直接通过 PDCCH order或 MAC CE的 方式通过激活的 CC通知 UE在失步后被去激活的一个或多个 CC上进行随机 接入过程, 随后, UE则会唤醒该一个或多个 CC进行随机接入进行同步, 从 而激活该 CC; 若 UE在该 CC上进行了随机接入过程, 则该 CC重新进入激 活状态。
实施中, UE在去激活的 CC上发起随机接入过程的作用也与网络侧指示 发起随机接入过程相同。
实施中, 网络侧也可以通过 PDCCH order、 MAC CE, RRC信令之一或 者其组合指示 UE激活去激活的 CC;。
针对当前 UE对工作栽波的上行同步定时提前量( TA )的维护可能是 UE 级别的, TA組级别的和 CC級别的三种情况, UE的处于失步去激活状态的 CC被激活的方式分别以网络侧为例进行说明如下, 此处由于 special cell不会 被去激活, 故下属说明的 CC不包含 special CC, 具体实施中, UE主动发起 的激活过程也与之类似, 参考实施即可,
1、 UE按照 CC级别来维护各个 CC的同步失步状态。
该方式下, 网络侧直接通过 PDCCH order或 MAC CE的方式通过激活的 CC通知 UE在失步后去激活的一个或多个 CC上进行随机接入过程,随后 UE 则唤醒该一个或多个 CC进行随机接入进行同步, 从而激活该 CC; 若 UE在 该 CC上进行了随机接入过程, 则该 CC重新进入激活状态。
2、 UE按照 TA组级别来维护各个 CC的同失步状态。
该方式下, 网络侧直接通过 PDCCH order或 MAC CE的方式通过激活的 CC通知 UE在失步后去激活的一个或多个 CC上进行随机接入过程,随后 UE 则唤醒该一个或多个 CC进行随机接入进行同步, 从而激活该 CC所属 TA组 内的所有 CC; 若 UE在该 TA组内某个 CC上进行了随机接入过程, 则该 TA 组内所有 CC都重新进入激活状态,
3、 UE按照 UE级别来维护各个 CC的同失步状态;
该方式下, 网络侧直接通过 PDCCH order或 MAC CE的方式通过激活的 CC (即 special cell )通知 UE进行同步, 从而唤醒所有 CC进入激活状态。 若 UE自身发起了随机接入过程, 则所有 CC重新进入激活状态。
由上述实施例可见,在实施中,既可以由网络侧确定 CC的同步与失步状 态后由网络侧指示去激活;也可以由 UE自行在确定 CC的同步与失步状态后 由 UE去激活;
在去激活 CC后, 激活去激活后的 CC是一个相对独立的过程, 其同样可 以经由网络侧指示后激活, 也可由 UE自行激活。 程的组合得到相应的不同的技术方案, 比如:
1、 网络侧指示去激活, 网络侧指示激活;
2、 网络侧指示去激活, UE激活;
3、 UE去激活, 网络侧指示激活;
4、 UE去激活, UE激活;
具体实施中可以根据需要进行各种可能的结合,只要能够利用 CC的失步 状态, 结合去激活过程, 并用以获得省电的作用则都是可行的, 这也是本领 域技术人员容易获知的。
基于同一发明构思, 本发明实施例中还提供了一种网络侧设备, 由于该 设备解决问题的原理与一种上行同步处理方法相似, 因此该设备的实施可以 参见方法的实施, 重复之处不再赘述。

为了描述的方便, 以上所述装置的各部分以功能分为各种模块或单元分 别描述。 当然, 在实施本发明时可以把各模块或单元的功能在同一个或多个 软件或硬件中实现.
由上述实施例可见, 在本发明实施例提供的技术方案中, 在多载波系统 中, 网络测使 UE工作栽波中失步状态栽波自动进入去激活状态, 以及再同步 后自动恢复激活状态, 从而达到省电的目的。
在 LTE-A系统中, 为了支持更高的峰值速率, 引入了栽波聚合技术。 但 是, 由于多栽波的引入, UE需要同时工作在多个栽波上, 而这也使得 UE的 电量消耗极度增加。
由于目前 LTE-A协议中尚无明确多栽波系统上行失败后的处理机制的描 述。 同时, 在移动通信系统中由于多栽波的引入, 当 UE的工作 CC处于失步 状态, 则表征 UE当前需要传输的数据较少, 当出现该情况时, 如果 UE继续 处于监听并收发准备的状态, 那么对 UE来说就处于比较费电的状态。
本发明实施例中, 由于在 CC处于失步状态时,便去激活处于失步状态的 CC。 由于能够及时地将不同步的 CC去激活, 从而也达到让 UE更加省电, 延长电池寿命的目的。
