Description

一种信道状态信息的发送方法和用户设备
技术领域
本发明涉及移动无线通信领域, 特别是涉及无线通信系统中信道状态信 息的发送方法及用户设备。 背景技术
在长期演进系统(LTE: Long Term Evolution ) 中, 上行需要传输的控制 信令有正确 /错误应答消息 ( ACK/NACK: Acknowledgement/Negative Acknowledgement ) , 以及反映下行物理信道状态的信息( CSI: Channel State Information )的三种形式: 信道质量指示 ( CQI: Channels quality indication ) 、 预编码矩阵指示 (PMI: Pre-coding Matrix Indicator ) 、 秩指示 (RI: Rank Indicator ) 。
LTE 系统中, ACK/NACK应答消息在物理上行控制信道( PUCCH: Physical Uplink Control Channel )上以格式 1/1 a/lb ( PUCCH format 1/lal/b )传 输, 如果用户设备 ( UE: User Equipment )需要发送上行数据时, 则在物理 上行共享信道(PUSCH: Physical Uplink Shared Channel )上传输, 上报的 CSI 的可以是周期性的, 也可以是非周期性的, 具体的反馈如表 1所示:
Figure imgf000003_0001
表 1 周期性和非周期性上报时对应的上行物理信道
其中,如果 UE不需要发送上行数据,则周期上报的 CSI在 PUCCH上以 格式 2/2a/2b ( PUCCH format2/2a/2b )传输, 如果 UE需要发送上行数据时, 则周期上报的 CSI在 PUSCH上传输; 非周期性上报的 CSI只在 PUSCH上传 输。 高层信令半静态配置 UE在 PUCCH上周期上报不同的 CQI, PMI和 RI 信息, 上报时使用的上报模式如表 2所示, 每一种下行传输模式都有对应的 上才艮模式。
Figure imgf000004_0001
表 2 上报模式
LTE中定义了 4中 CQI/PMI信息和 RI信息上报类型,即支持 UE选择子 带 CQI信息反馈的上报类型 1, 支持宽带 CQI信息和 PMI信息反馈的上报类 型 2, 支持 RI信息反馈的上报类型 3 , 支持宽带 CQI信息的上报类型 4。
为 了 满足高级国 际电信联盟 ( International Telecommunication Union-Advanced, 简称为 ITU-Advanced )的要求, 作为 LTE演进标准的高级 长期演进(Long Term Evolution Advanced, 简称为 LTE-A ) 系统需要支持更 大的系统带宽 (最高可达 100MHz ) , 并需要后向兼容 LTE现有的标准。 在 现有 LTE系统的基础上,可以通过将 LTE系统的带宽进行合并来获得更大的 带宽, 这种技术称为载波聚合(Carrier Aggregation, 简称为 CA )技术。 该技 术能够提高 IMT-Advance系统的频谱利用率、 緩解频谱资源紧缺, 进而优化 频谱资源的利用。 所述载波聚合的 LTE 系统带宽可以看作分量载波 ( Component Carrier, 简称为 CC ) , 每个分量载波也可以称为一个服务小区 ( Serving Cell ) , 也就是说一个频谱可以由 η个分量载波(或服务小区)聚 合而成。 一个 RIO UE的资源由频域的 η个分量载波(或服务小区)构成, 其中, 一个服务小区称为主小区 (Primary cell )或主分量载波, 其余服务小 区称为辅小区 (Secondary cell )或辅分量载波。 LTE-A系统中, CQI/PMI信 息, RI信息的上报类型也扩展为: 支持 UE选择子带 CQI信息的上报类型 1 , 支持子带 CQI和第二个 PMI反馈的上报类型 la, 支持宽带 CQI信息和 PMI 信息反馈的上报类型 2, 上报类型 2b, 上报类型 2c, 支持宽带 PMI反馈的上 报类型 2a,支持 RI信息反馈的上报类型 3 ,支持宽带 CQI信息的上报类型 4, 支持 RI 和宽带 PMI反馈的上报类型 5 , 支持 RI和 ΡΉ ( Precoder Type Indication, 预编码类型指示) 的上报类型 6。
LTE-A的讨论过程中, 提出引入几种大负载的 PUCCH格式来支持周期 CSI传输, 比如现在的 PUCCH格式 3 , 或者增强的 PUCCH格式 3。
LTE-A系统规定: 如果 UE配置了多个下行服务小区, 在任一子帧内, UE只传输一个下行服务小区的周期 CSI信息, 即多个服务小区的周期 CSI 报告釆用时分复用的方式传输。 现有技术还规定了如果多个服务小区的周期 CSI信息需要在同一子帧传输的处理方式: 选择一个下行服务小区对应的周 期 CSI信息传输, 打掉其他下行服务小区对应的周期 CSI信息。 具体的选择 方法为: 根据各个下行服务小区的周期 CSI上报类型对应的优先级选择, 即 选择上报类型优先级高的服务小区的周期 CSI信息传输, 如果多个下行服务 小区对应的周期 CSI信息的上报类型对应的优先级相同, 根据服务小区索引 值选择, 即选择服务小区索引值最小的服务小区的周期 CSI信息传输。 优先 级最高的上报类型是: 上报类型 3 , 上报类型 5, 上报类型 6和上报类型 2a; 优先级最低的上报类型是: 上报类型 1和上报类型 la; 其他上报类型的优先 级在这两者之间。
发明内容
LTE-A系统中不支持多个下行服务小区的周期 CSI报告同时传输, 而是 釆用时分复用的方式传输多个下行服务小区的周期 CSI报告, 所以基站获得 各个下行服务小区的信道质量信息延迟, 对调度产生影响, 从而影响系统的 吞吐量, 浪费上行资源。 釆用时分复用的方式也不能完全避免多个下行服务 小区的周期 CSI信息同时传输, 当多个下行服务小区的周期 CSI报告需要同 时传输时, 只发送一个下行服务小区的周期 CSI才艮告, 打掉其他下行服务小 区的周期 艮告, 也会使得系统的性能下降。 而且在后续的版本中, 由于 新技术的引入,如协作多点传输系统( Coordinated Multi-Point Transmission and Reception , 简称为 CoMP )需要发送的周期 CSI报告的下行小区个数也会增 加, 延迟或打掉对系统的影响是不能忽视的。
本发明要解决的技术问题是提供一种信道状态信息的发送方法和用户设 备, 有效地减少由于下行小区的周期 CSI报告延迟或打掉对系统的影响, 提 高系统的性能。

假设高层信令指示支持 3个小区的周期 CSI同时发送, 当前子帧内需要 发送的周期 CSI的下行小区个数为 6, UE从 6个下行小区中选择 3个小区的 周期 CSI上报, 这 3个小区的周期 CSI报告分别为 {«...4} , 和
本实施例中, 预定义的规则是规则一, UE根据高层信令配置的 PUCCH 格式发送周期 CSI,本实施例中,高层信令配置的 PUCCH格式是新的 PUCCH 格式。
假设常规 CP下, 新的 PUCCH格式为: 图 4所示的 PUCCH格式 3且编 码过程如图 2 (c)所示, 交织是基于调制符号的交织, 每个 RM (L, 0) 的 输入序列上行控制信息序列 1, 上行控制信息序列 2, 上行控制信息 3分别由 以下几种方案中的一种得到:
方式一: 3个小区的周期 CSI信息分别作为上行控制信息序列 1, 上行控 制信息序列 2, 上行控制信息序列 3;

由于 PUCCH格式 3最多可承载 24个调制符号 ,那么每个 RM 的编码后输出序列长度为 16。 由于编码后釆用基于调制符号的交织, 所以第 一个 RM (L, 0) 的输出映射为图 4中的调制符号

由于增强的 PUCCH格式 a最多可承载 48个调制符号 , 那么 每个 RM的编码后输出序列长度为 24。 所以第一个 RM (L, 0)的输出映射 为图 5或图 6中的调制符号 {H. 第二个 RM (L, 0) 的输出映射为 图 5或图 6中调制符号 第三个 RM (L, 0) 的输出映射为图 5 或图 6中调制符号 { 4, 5,..., 5}, 第四个 RM (L, 0)的输出映射为图 5或图 6中调制符号 { 6,&7,...,&7}。 如果釆用图 2(d)所示的编码过程, 且交织为基于 调制符号的交织, 第一个 RM (L, 0) 的输出映射为图 5或图 6中的调制符 -f {S^S^S^S^S^S^S^S^S^S^S^S , 第二个 RM (L, 0) 的输出映射为 图 5或图 6中的调制符号 {^ , , ,^, ,^,^, ,^,^},第三个 RM(L,
