Description

一种载波聚合系统下 PHR的处理方法和设备 本申请要求于 2010年 9 月 29 日提交中国专利局， 申请号为 201010299887.0, 发明名称为 "一种载波聚合系统下 PHR 的处理方 法和设备"的中国专利申请的优先权， 其全部内容通过引用结合在本 申请中。 技术领域
本发明涉及通信技术领域， 尤其涉及一种载波聚合系统下 PHR 的处理方法和设备。 背景技术
( 1 ) CA ( Carrier Aggregation, 载波聚合 )
LTE-A( LTE- Advanced,高级 LTE )系统的峰值速率较 LTE( Long Term Evolution,长期演进）系统有很大的提高，要求达到下行 lGbps, 上行 500Mbps, 同时， LTE-A系统要求和 LTE系统具有 4艮好的兼容 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系统引入了载波聚合技术。 其中， 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, 成员载波）。
具体的， 在载波聚合系统中， 各个成员载波可以是连续， 也可以 是非连续的， 各成员载波间的带宽可以相同， 也可以不同。 其中， 为 了保持和 LTE系统的兼容，每个成员载波的最大带宽限制为 20MHz, 且目前一般认为 CC最大个数为 5个。
( 2 ) LTE PHR ( Power Headroom Reporting, 功率余量上^ 1艮 )
LTE系统中 PHR的含义为： UE ( User Equipment, 用户设备） 最大发射功率和估计的发射功率之间的差值， 其中， PH计算公式为： PH (功率余量） = PMAX ( UE最大发射功率） - PPUSCH (携带该 PHR信息的上行共享信道 PUSCH使用的功率）。 在实现本发明的过程中，发明人发现现有技术中至少存在以下问 题：
LTE系统中 UE只工作在 1个 DL (下行） /UL (上行） CC上， 当该 CC的路损发生变化并达到门限时， 则会触发 PHR的上报。 但 是在 LTE-A载波聚合中， 当 UE配置了多个上行和多个下行 CC时， 每个 CC的路损变化如何影响 UE PHR的上报过程， 现有技术中并没 有相应的处理方法。 发明内容
本发明实施例提供一种载波聚合系统下 PHR 的处理方法和设 备， 以触发 PHR, 并将相应的 PH信息上报给网络侧。
为了达到上述目的，本发明实施例提供一种载波聚合系统下功率 余量上报 PHR的处理方法， 包括：
用户设备获取当前处于激活状态的上行载波对应的路损变化； 所述用户设备根据所述路损变化判断是否触发 PHR;
如果是， 所述用户设备获取需要上报的功率余量 PH信息， 并上 报所述 PH信息。
本发明实施例提供一种用户设备， 该设备包括：
获取模块，用于获取当前处于激活状态的上行载波对应的路损变 化；
判断模块，用于根据所述获取模块获取的所述路损变化判断是否 触发 PHR;
处理模块， 用于当判断结果为是时， 获取需要上报的功率余量 PH信息， 并上报所述 PH信息。 与现有技术相比， 本发明至少具有以下优点：
在载波聚合系统下， UE可根据当前处于激活状态的上行载波上 的路损变化情况来触发 PHR, 从而解决了载波聚合系统下可以获得 多个 pathloss的情况下， UE如何触发 PHR的问题。 附图说明
图 1为现有技术中 RRC层 PHR相关配置的示意图；
图 2为现有技术中 MAC子头的示意图；
图 3为现有技术中 PHR MAC CE的示意图；
图 4为本发明实施例一提供的一种载波聚合系统下 PHR的处理 方法流程示意图；
图 5为本发明实施例八提供的一种用户设备结构示意图。 具体实施方式
下面结合附图和实施例，对本发明的具体实施方式作进一步详细 描述：
在 LTE系统中， PHR的相关技术包括：
( 1 )与 PHR相关的 RRC ( Radio Resource Control, 无线资源控 制 )层参数配置。 其中， PHR上报的目的是通知 eNB (基站 )该 UE 最大发射功率和 UE估计的 UL-SCH ( UL-Shared Channel, 上行共享 信道）信道发射功率之间的差值。 PHR上报参数由 RRC层配置， 且 相关参数包括： 定时器参数、 周期性 PHR 上报定时器 periodicPHR-Timer的周期、 禁止 PHR上报定时器 prohibitPHR-Timer 的长度、 触发 PHR上报的路损变化参数 dl-PathlossChange, 如图 1 所示的 RRC层 PHR相关配置的示意图。
( 2 ) PHR的触发机制。 其中， 当满足以下条件之一时即可触发
PHR:
UE有上行资源可用， prohibitPHR-Timer超时且距离最近一次 PHR上报路损变化超过 dl-PathlossChange dB;
periodicPHR- Timer超时；
高层初次配置 PHR或者对 PHR进行重配。 ( 3 ) PHR上报格式。 在 LTE系统中进行 PHR上报时， 包括一 个 MAC ( Media Access Control,介质访问控制 )子头和一个 MAC CE ( Control Element, 控制单元；)， 如图 2所示的 MAC子头的示意图， 以及图 3所示的 PHR MAC CE的示意图。
其中， 各域的含义包括：
LCID ( Logical Channel ID, 逻辑信道标识）： 用于标识对应负荷 部分的逻辑信道号，对于 PHR上报来说， LCID用于标识对应的负荷 部分为 PHR。
E: 扩展比特， 用于指示下一个 byte是 MAC子头还是 MAC负 荷。
R: 预留比特。
PH: 上行功率余量。
( 4 ) PHR上报过程。 如果 UE有上行可用资源， 一旦触发 PHR 上报， 则按照逻辑信道的优先级进行上报， 如果当前为该 UE分配的 上行资源可以容纳一个 PHR MAC CE, 则： 通知物理层计算 PH值； 通知 Multiplexing and Assembly (复用和集合）过程生成 PHR MAC CE; 启动 /重启 periodicPHR-Timer; 启动 /重启 prohibitPHR-Timer; 取 消所有触发的 PHR。
另外， 在 LTE-A系统中， 为了支持更高的峰值速率， 引入了 CA 技术， 此时， LTE-A CA中 PHR相关的情况包括：
UE工作的多个 UL CC上，每个 CC都有自己的 PH信息， 即 PH 信息是以 CC为单位的；
当 1个 ΤΉ ( Transmission Time Interval, 传输时间间隔） 内有多 个 CC上报 PH信息时， 将多个 CC的 PH信息打包在 1个 MAC CE 中上传给网络；
UE配置的 UL CC上对应的 pathloss (路损 ) reference (参考 ) CC可以来自 PCdl, 也可以来自其 SIB2 ( System Information Block, 系统信息块） linked (关联） 的 DL CC;
UE可在多个 DL CC上测量 pathloss, 去激活 DL CC上也会测量 到 pathloss;
上行可能会 I入激活去激活的状态。
针对现有技术中并没有 LTE-A 载波聚合技术下如何实现 UE PHR上报过程的问题， 本发明实施例提出一种载波聚合系统下 PHR 的处理方法和设备， UE侧当前处于激活态的上行载波所对应的路损 变化超过门限时， UE触发 PHR, 从而解决了载波聚合系统下可以获 得多个 pathloss的情况下， UE如何触发 PHR的问题。
下面将结合本发明实施例中的附图，对本发明中实施例的技术方 案进行清楚、 完整地描述， 显然， 所描述的实施例仅仅是本发明的一 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。 本发明实施例一提供一种载波聚合系统下 PHR的处理方法， 如 图 4所示， 该方法包括以下步骤：
步骤 401 , 用户设备获取当前处于激活状态的上行载波对应的路 损变化。 其中， 该上行载波对应的路损变化为上行载波距离最近一次 PHR上报时的路损变化。
本发明实施例中， 在 UE侧， 只有当前处于激活态的上行载波所 对应的路损变化超过门限， 才触发 PHR上报。 因此， UE需要获取当 前处于激活状态的上行载波距离最近一次 PHR上报时的路损变化。
进一步的， 用户设备需要获取当前具有 UL Grant (许可）的上行 载波距离最近一次 PHR上报时的路损变化。
进一步的， 考虑到上行重传的情况， 需要在 UL Grant中排除上 行重传的情况， 此时， 该上行载波为具有 new UL Grant的上行载波， 即用户设备需要获取当前具有 new UL Grant的上行载波距离最近一 次 PHR上报时的的路损变化。
步骤 402,用户设备根据该路损变化判断是否触发 PHR。如果是， 转到步骤 403, 否则， 结束流程。 本发明实施例中， 根据 prohibitPHR-Timer和 periodicPHR-Timer 的维护情况， 本步骤有以下 3种处理方式：
( 1 ) prohibitPHR-Timer是基于用户设备 ( per UE ) 维护， 且 periodicPHR-Timer是基于用户设备维护。
本步骤中， 当 UE侧在任何一个 UL CC (上行载波 )上有 new UL Grant时， UE可根据路损变化判断是否满足预设触发条件：
prohibitPHR-Timer超时，且至少 1个处于激活状态的上行 CC距 离最近一次 PHR上报的路损变化（即当前获得的下行^员相对于最 近一次 UE PHR传输时的路损的变化 )超过预设门限；
periodicPHR- Timer超时；
配置或者重配 PHR功能；
当然， 实际应用中， 该预设触发条件并不局限于此， 对于其他的 触发条件， 本发明实施例中不再赘述。
如果满足预设触发条件的一种或几种时， 则确定触发 PHR, 否 则， 确定不触发 PHR。
( 2 ) prohibitPHR-Timer是基于成员载波（per CC ) 维护， 且 periodicPHR-Timer是基于用户设备维护。
本步骤中， 当 UE侧在某个 UL CC上有 new UL Grant时， UE可 根据路损变化判断每个处于激活状态的上行载波是否满足预设触发 条件， 即每个激活 CC上的 PHR触发的判断条件如下：
该处于激活状态的 UL CC上的 prohibitPHR-Timer超时， 且相对 于最近一次 UE PHR传输时， 该 CC上距萬最近一次 PHR上报的路 损变化（即 UL CC对应的路损变化）超过预设门限；
UE的 periodicPHR-Timer超时；
配置或者重配 PHR功能；
当然， 实际应用中， 该预设触发条件并不局限于此， 对于其他的 触发条件， 本发明实施例中不再赘述。
如果满足预设触发条件的一种或几种时， 则确定触发 PHR, 否 则， 确定不触发 PHR。 ( 3 ) prohibitPHR-Timer 是基于成员 载波维护 ， 且 periodicPHR-Timer ^^于成员载波维护。
本步骤中， 当 UE侧在某个 UL CC上有 new UL Grant时， UE可 根据路损变化判断每个有 UL Grant的成员载波是否满足预设触发条 件， 即每个 CC上的 PHR触发的判断条件如下：
该 CC的 prohibitPHR-Timer超时， 且该 CC距离最近一次 PHR 上报的路损变化超过预设门限；
该 CC上的 periodicPHR-Timer超时；
配置或者重配 PHR功能；
当然， 实际应用中， 该预设触发条件并不局限于此， 对于其他的 触发条件， 本发明实施例中不再赘述。
如果满足预设触发条件的一种或几种时， 则确定触发 PHR, 否 则， 确定不触发 PHR。
步骤 403, 用户设备获取需要上报的功率余量 PH信息， 并上报 该 PH信息。
本发明实施例中， 根据 prohibitPHR-Timer和 periodicPHR-Timer 的维护情况， 本步骤也有对应步骤 402的 3种处理方式：
( 1 ) prohibitPHR-Timer 是基于用 户 设备维护 ， 且 periodicPHR-Timer是基于用户设备维护。
本步骤中， 用户设备需要获取所有处于激活状态的上行载波的 PH信息， 并将所有处于激活状态的上行载波的 PH信息携带于 PHR MAC CE中上报给网络侧。
具体的， 当 UE PHR被触发， 则需要上报该 UE 的所有激活 UL CC上的 PH信息， 并组织 PHR MAC CE, 将所有激活的 UL CC的 PH信息携带于 PHR MAC CE中上报给网络侧。 其中， 在通过 PHR MAC CE上>¾时，可以通过本成员载波或者其它成员载波上 >¾该 PHR MAC CE; 而当通过其它成员载波上报该 PHR MAC CE时， 该 PHR MAC CE中需要携带成员载波指示信息。
另 外， 在上报该 PH 信息后 ， 还需要启动或重启 periodicPHR-Timer; 启动或重启 prohibitPHR-Timer。
( 2 ) prohibitPHR-Timer 是基于成员 载波维护 ， 且 periodicPHR-Timer是基于用户设备维护。
本步骤中， 如果 PHR是由于 prohibitPHR-Timer超时（即处于激 活状态的 UL CC上的 prohibitPHR-Timer超时， 且 CC上距离最近一 次 PHR上报的路损变化超过预设门限 )触发的， 则用户设备需要获 取该上行载波（即触发 PHR的上行载波） 的 PH信息， 并将该上行 载波的 PH信息携带于 PHR MAC CE中上报给网络侧。 即组织 PHR MAC CE时只包含该触发 PHR的 CC的 PH信息。 另夕卜， 在上报该 PH信息后， 还需要重启该 CC对应的 prohibitPHR-Timer。
如果 PHR是由于 periodicPHR-Timer超时、 和 /或， 配置或重配 PHR 功能触发的， 则用户设备需要获取所有处于激活状态的上行载 波的 PH信息， 并将所有处于激活状态的上行载波的 PH信息携带于 PHR MAC CE中上报给网络侧。 即组织 PHR MAC CE时需要包含所 有激活的 UL CC的 PH信息。 其中， 在通过 PHR MAC CE上报时， 可以通过本成员载波或者其它成员载波上 >¾该 PHR MAC CE; 而当 通过其它成员载波上报该 PHR MAC CE时，该 PHR MAC CE中需要 携带成员载波指示信息。
另外， 在上报该 PH 信息后， 还需要重启所有激活 CC 上的 prohibitPHR- Timer和 periodicPHR-Timer。
( 3 ) prohibitPHR-Timer 是基于成员 载波维护 ， 且 periodicPHR-Timer ^^于成员载波维护。
本步骤中， 用户设备需要获取触发 PHR的上行载波的 PH信息， 并将该触发 PHR的上行载波的 PH信息携带于 PHR MAC CE中上报 给网络侧。即组织 PHR MAC CE时， PHR MAC CE中只包含触发 PHR 的 UL CC的 PH信息。 其中， 在通过 PHR MAC CE上报时， 可以通 过本成员载波或者其它成员载波上 "¾该 PHR MAC CE; 而当通过其 它成员载波上报该 PHR MAC CE时，该 PHR MAC CE中需要携带成 员载波指示信息。 另外， 在上报该 PH信息后， 还需要启动或重启上述触发 PHR 的 UL CC所对应的 prohibitPHR-Timer和 prohibitPHR-Timer。 本发明实施例二提供一种载波聚合系统下 PHR的处理方法， 本 实施例中， prohibitPHR-Timer是 per UE维护的， periodicPHR-Timer 是 per UE维护。
