Description

非周期信道质量信息上报的方法、 装置及终端
技术领域
本发明涉及通信领域，具体而言， 涉及一种非周期信道质量信息（CQI ) 上报的方法、 装置及终端。 背景技术
为了向用户提供诸如语音、 分组数据、 广播等各种业务内容， 无线通信 网络被广泛部署， 为了满足用户日益增长的通信质量和通信速率需求， 无线 通信技术（无线网络） 不断的演进发展。 无线通信网络已经从全球移动通信 系统（ Global System For Mobile Communication, GSM ) /通用无线分组业务 系统（ General Packet Radio Service, GPRS )第 2代 /第 2.5代移动通信网络演 进到通用移动通信系统 (Universal Mobile Telecommunications System, UMTS) 第 3代移动通信网络。 而为了更好的提高频语使用效率， 满足用户飞速增长
3GPP )组织又在 UMTS的基础上提出了第 4代移动通信技术长期演进（ Long Term Evolution, LTE )及其进一步演进技术 "高级长期演进" （ Long Term Evolution Advance , LTE-A ) 。
为向移动用户提供更高的数据速率， LTE-A提出了载波聚合技术（ Carrier Aggregation, 简称 CA ) , 其目的是为具有相应能力的 UE提供更大宽带， 提 高 UE的峰值速率。 LTE中， 系统支持的最大下行传输带宽为 20MHz, 载波 聚合是将两个或者更多的分量载波（Component Carriers, 简称 CC )聚合起 来支持大于 20MHz, 最大不超过 100MHz的传输带宽。 UE进入连接态后可 以同时通过多个分量载波（如 CC1和 CC2 )与基站进行通信， 基站会通过显 式的配置或者按照协议约定为 UE指定一个主分量载波（ Primary Component Carrier, PCC ),其他的分量载波称为辅分量载波（ Secondary Component Carrier, SCC ) 。 在 PCC上的服务小区称为主服务小区 （Primary Cell, Pcell ) , 在 SCC上的服务小区称为辅服务小区 （Secondary Cell, Scell ) 。
为了满足 LTE-A的性能指标， 尤其是达到 LTE-A对小区边缘用户的性 能要求， 多点协作（Coordinated Multi point, CoMP )传输技术被提出。 CoMP 传输技术被看做是提高小区边缘用户性能， 有效抑制小区间干扰的重要技术 之一。 LTE-A系统可以通过 CoMP技术来增加高数据速率的覆盖， 从而提高 小区边缘的吞吐量， 进一步提高系统吞吐量。 所谓 CoMP是指地理位置上分 离的多个 eNB ( evolved NodeB , 演进型基站） ， 或者称多个传输节点 ( Transmission Point, TP )参与和同一个 UE的数据传输。 为此， 在 LTE系 统已有的传输模式 1-9 ( Transmission Mode, TM )的基础上， 为 CoMP专门 设计了 TM10。
LTE系统中， UE会上报信道质量指示（ Channel Quality Indicator , CQI ) 以便网络侧进行合理的调度， CQI有周期和非周期上报， 除非特别说明， 本 文指的 CQI上报都是非周期上报。 对于 CQI上报的配置， 在引入 CoMP之 前， 按照比特位图的形式配置需要上报 CQI的服务小区， 即一共为终端配置 两个触发集合称为第一触发集合（需要上报 CQI的服务小区对应的比特设置 为 1 , 其他设置为 0 )和第二触发集合（需要上报 CQI的服务小区对应的比 特设置为 1 , 其他设置为 0 ) ， 网络侧会通过物理层信令指示终端上报 CQI 请求， 信令内容对应下表中第一列， 比如指示上报 '10， （从下表可以看出 对应第一触发集合）的 CQI时， 终端查找第一个触发集合中配置了需要上报 CQI的小区并将这些小区的 CQI上报， 指示上报 '11 '的情况跟， 10 '的类 似， 当指示上报， 01 '的 CQI时， 需要上报 CQI的小区是同时满足以下条件 的小区：小区被分配了上报 CQI的资源，且小区的非周期 CQI触发值为 '01，。

引入 CoMP 的时候， 每个服务小区必须按照信道状态信息处理进程 ( Channel State Information, CSI-process )来配置 CQI, 每个小区可以配置多 个 CSI-process, 每个 CSI-process都配置单独的非周期 CQI触发值， 非周期 CQI触发值可以是 'ΟΓ , '10' , '11' , 网络侧会通过物理层信令指示 终端上报 CQI请求，信令内容对应下表中第一列， 比如指示上报如 '10， （从 下表可以看出对应第一触发集合） 的 CQI 时， 终端查找每个服务小区的 CSI-process的 CQI配置，非周期 CQI触发值为 '10，的服务小区的 CSI-process 都需要进行 CQI上报，指示上报 '11 '的情况跟， 10 '的类似， 当指示上报， 01 '的 CQI时， 被分配了上报 CQI的资源的服务小区， 并且该服务小区配置 的非周期 CQI触发值也为， 01 '才需要上报该服务小区下所有的 CSI-Process 的 CQL

Ί Γ report is triggered for a 2nd set of CSI process(es) configured by higher layers )
另外，上述物理层信令中指示终端上报 CQI的请求，只能对应表 7.2.1-1A 和表 7.2.1-1B中的一张表。 当终端同时有连接的多个服务小区， 都没有配置 CoMP时， CQI请求就对应表 7.2.1-1A,当多个服务小区都配置了 CoMP时， CQI请求就对应表 7.2.1-1B, 当多个服务小区部分配置了 CoMP, CQI请求 就对应表 7.2.1-1B, 那么没有配置 CoMP的小区无法对应表 7.2.1-1B就无法 上报 CQI, 网络侧无法对这些服务小区进行合理的调度。

下面结合附图和具体实施例对本发明所述技术方案作进一步的详细描述, 以使本领域的技术人员可以更好的理解本发明并能予以实施， 但所举实施例 不作为对本发明的限定。 需要说明的是， 在不冲突的情况下， 本申请中的实 施例及实施例中的特征可以相互组合。
实施例 1
本发明非周期信道质量信息 （CQI )上报的方法， 如图 1 所示， 该方法 包括：
步骤 101 : 网络侧对终端进行非周期 CQI触发配置， 其中， 同时存在配 置多点协作 （CoMP ) 的小区和未配置 CoMP的小区时， 未配置 CoMP的小 区的非周期 CQI触发配置信息包括按小区配置的非周期 CQI触发值；
具体地，未配置 CoMP的小区的非周期 CQI触发配置信息可以即包括按 小区配置的非周期 CQI触发值，也包括按比特位图方式对未配置 CoMP的小 区进行非周期 CQI触发值； 或者仅包括按小区配置的非周期 CQI触发值。 本文中，按小区配置未配置 CoMP的小区的非周期 CQI触发值指即将该 未配置 CoMP的小区认为是只有一个 CSI-process的情况， 比照配置 CoMP 的小区中的 CSI-Process的配置方式进行配置。
优选地，如图 2所示，所述网络侧对终端进行非周期 CQI触发配置包括： 步骤 201 : 网络侧判断终端的多个服务小区中是否存在配置多点协作 ( CoMP ) 的小区；
步骤 202: 判断存在配置 CoMP的小区时， 所述按小区进行非周期 CQI 触发值配置， 否则按照比特位图的形式进行非周期 CQI触发信息配置；
具体地， 判断存在配置 CoMP的小区时包括两种情形， 一种情形是， 终 端的所有服务小区都是配置 CoMP的小区， 还有一种情形是终端的部分服务 小区是配置 CoMP的小区， 另一部分是未配置 CoMP的小区， 在该具体实施 例中， 配置 CoMP的小区和未配置 CoMP的小区都按小区进行非周期 CQI 触发值配置。
可理解地，对配置 CoMP的小区按小区进行非周期 CQI触发值配置， 即 为小区中的每个 CSI-process都配置一个非周期 CQI触发值。
如上文所述，对于同时存在配置 CoMP的小区和未配置 CoMP的小区的 情形， 对于未配置 CoMP的小区也可以同时按照比特位图的方式配置非周期 CQI触发值。
不存在配置 CoMP 的小区的情形即终端的所有服务小区都是未配置
CoMP的小区， 此时即按照比特位图的方式进行非周期 CQI触发值配置。
步骤 102: 所述网络侧向所述终端发送信道状态信息 （CSI ) 上^艮请求； 步骤 103: 所述网络侧接收所述终端上报的 CQI。
所述 CSI上报请求中包括非周期 CQI上报索引值， 同时存在配置 CoMP 的小区和未配置 CoMP的小区时， 其中： 所述非周期 CQI上报索引值为 'ΟΓ时， 上报的 CQI对应的服务小区和 / 或服务小区 CSI-process包括被分配了上报 CQI资源且非周期 CQI触发值为 '01' 的服务小区或该服务小区下的所有 CSI-Process;
所述非周期 CQI上报索引值为 '10'时， 上报的 CQI对应的服务小区和 / 或服务小区 CSI-process 包括非周期 CQI 触发值为 ' 10' 的服务小区或 CSI-Process;
所述非周期 CQI上报索引值为 '11'时， 上报的 CQI对应的服务小区和 / 或服务小区 CSI-process 包括非周期 CQI 触发值为 ' 11 ' 的服务小区或 CSI-Process。
实施例 2 明的， 本实施例 2从用户设备 (UE, 本文中也称为终端）的角度对本发明方法 进行说明。
如图 3 所示， 本发明非周期信道质量信息 （CQI )上报的方法实施例 2 包括：
步骤 301 :终端接收网络侧发送的所述终端的非周期 CQI触发配置信息； 如上文所述， 同时存在配置多点协作 （CoMP ) 的小区和未配置 CoMP 的小区时，未配置 CoMP的小区的非周期 CQI触发配置信息包括按小区配置 的非周期 CQI触发值。
步骤 302: 所述终端接收网络侧发送的信道状态信息 （CSI ) 上报请求； 步骤 303: 所述终端向网络侧上 ^艮 CQI, 其中， 同时存在配置 CoMP的 小区和未配置 CoMP的小区时，所述上 "^的 CQI对应的未配置 CoMP的小区 是基于按小区配置的非周期 CQI触发值确定的。
所述 CSI上报请求中包括非周期 CQI上报索引值， 如图 4所示， 所述终 端向网络侧上 ^艮 CQI的步骤包括：
步骤 401 : 所述终端判断服务小区中是否存在配置 CoMP的小区； 步骤 402: 所述终端根据所述非周期 CQI上报索引值匹配非周期 CQI触 发值， 其中， 判断存在配置 CoMP的小区时， 基于按小区配置的非周期 CQI 触发值进行匹配， 否则基于按照比特位图的形式配置的非周期 CQI触发值进 行匹配；
具体地，终端可根据接收的非周期 CQI触发配置信息判断是否存在配置 多点协作 （CoMP ) 的小区。
具体地， 判断存在配置 CoMP的小区时包括两种情形， 一种情形是， 终 端的所有服务小区都是配置 CoMP的小区， 还有一种情形是终端的部分服务 小区是配置 CoMP的小区， 另一部分是未配置 CoMP的小区， 在该具体实施 例中， 在本实施例中， 无论哪一种情形都基于按小区配置的非周期 CQI触发 值匹配。
不存在配置 CoMP 的小区的情形即终端的所有服务小区都是未配置 CoMP的小区，此时基于按照比特位图的形式配置的非周期 CQI触发值匹配。
步骤 403: 所述终端获得并上 匹配的非周期 CQI触发值对应的小区或 CSI-process的 CQI。
根据上述实施例可以看出， 本发明中未配置 CoMP的小区的非周期 CQI 触发配置信息包括按小区配置的非周期 CQI触发值， 具体地：
当所有的服务小区的 CoMP都启用后，非周期 CQI触发配置都按小区配 置。
当部分服务小区的 CoMP配置取消以后， 可以保留按小区配置的方式。 当所有服务小区的 CoMP 配置都取消， 即所有的服务小区的都未配置 CoMP, 非周期 CQI触发配置回退成按照比特位图的方式配置。
本发明解决了终端的多个服务小区， 其中没配置 CoMP的服务小区无法 上报非周期 CQI的问题。
下文中将参考附图及应用实例对本发明详细说明。
如图 5所示为一种 CoMP部署场景示意图。图 5中 3个彼此相邻的小区， 小区 1的基站 1、 小区 2的射频拉远单元（ Remote Radio Head, RRH ) 2、 小 区 3的射频拉远单元 3共享 UE 的信道信息、 分布信息， 并基于这些信息进 行联合调度， 共同决定 UE的调度和 /或波束赋型。 其中基站 1与射频拉远单 元 2和 3之间用光纤连接。
