Description

上行控制信息的发送方法和装置
技术领域
本发明涉及通信领域, 具体而言, 涉及一种上行控制信息的发送方法和装置。 背景技术
长期演进 (Long Term Evolution, 简称为 LTE) 系统是第三代伙伴组织的重要计划, 图 1 示出了 LTE系统中基本帧结构的结构示意图, 如图 1所示, 帧结构分为无线帧、 半帧、 子帧、 和时隙四个等级, 其中, 一个无线帧的长度为 10毫秒 (ms), 一个无线帧由两个长度为 5ms 的半帧组成, 一个半帧由 5个长度为 1ms的子帧组成, 一个子帧由两个长度为 0.5ms的时隙 构成。
在 LTE的下行 HARQ中, 物理下行共享信道(Physical Downlink Shared Channel, 简称为 PDSCH) 的正确 /错误 (Acknowledgement/Negative Acknowledgement, 简称为 ACK/NACK) 应答消息,当终端(User Equipment,简称为 UE)没有物理上行共享信道(Physical Uplink Shared Channel, 简称为 PUSCH) 时, 是在物理上行控制信道 (Physical Uplink Control Channel, 简 称为 PUCCH)上发送的。 LTE定义了多种 PUCCH format (format格式), 包括 PUCCH format 1/la/lb和 format 2/2a/2b, 其中 format 1用来发送 UE的调度请求 (Scheduling Request, 简称 为 SR) 信号, format la和 lb 分别用来反馈 1 比特的 ACK/NACK应答信息和 2 比特的 ACK/NACK应答信息, format 2用来发送信道状态信息 (Channel States Information, 简称为 CSD o
在 LTE系统中, 频分双工 (Frequency Division Duplex, 简称为 FDD) 系统中, 由于上下 行子帧是一一对应的, 所以当 PDSCH只包含一个传输块时, UE要反馈 1比特的 ACK/NACK 应答信息, 当 PDSCH包含两个传输块时, UE要反馈 2比特的 ACK/NACK应答信息, UE使 用 PUCCH formatla/lb发送 1/2比特的 ACK/NACK应答信息。时分双工(Time Division Duplex, 简称为 TDD ) 系统中, 由于上下行子帧的不是一一对应的, 也就是说多个下行子帧对应的 ACK/NACK应答信息需要在一个上行子帧的 PUCCH信道上发送, 其中, 上行子帧对应的下 行子帧集合组成了" bundling window" o ACK/NACK 应答信息的发送方法有两种: 一种是 bundling (绑定方法), 该方法的核心思想是把需要在该上行子帧上反馈的各个下行子帧对应 的传输块的 ACK/NACK应答信息进行逻辑与运算。 如果一个下行子帧有 2个传输块, UE要 反馈 2比特的 ACK/NACK应答信息, 如果一个下行子帧只有一个传输块, UE要反馈 1比特 的 ACK/NACK应答信息, UE采用 PUCCH format la/lb来发送这 1/2比特的 ACK/NACK应 答消息; 另一种是 multiplexing (Multiplexing with Channel Selection, 信道选择) 方法, 该方 法的核心思想是利用不同的 PUCCH信道和该信道上不同的调制符号来表示需要在该上行子 帧上反馈的下行子帧的不同反馈状态, 如果下行子帧上有多个传输块, 那么先将下行子帧的 多个传输块反馈的 ACK/NACK进行逻辑与 (Spatial Bundling) 后再进行信道选择, UE采用 format lb with channel selection (格式 lb联合信道选择) 来发送 ACK/NACK应答消息。 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的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。在现有的 LTE系统的基础上,可以将 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、 缓解频谱资源紧缺, 进而优化频谱资源的利用。 为了获得更高的峰值频 谱效率, LTE-A 系统中, 上行支持多根传输天线, 即上行支持单天线传输模式和多天线传输 模式。 考虑到传输分集方式可以提高信道传输的可靠性, 改善接收信号的信噪比, 所以针对 PUCCH信道多天线传输模式的讨论都是基于传输分集方式的, 而且对于四天线的场景, 都是 通过对两天线虚拟化得到的。
在引入了载波聚合的系统中, 进行聚合的载波称为分量载波(Component Carrier, 简称为 CO,也称为一个服务小区(Serving Cell)。同时,还提出了主分量载波 /小区(Primary Component Carrier/Cell, 简称为 PCC/PCell)和辅分量载波〃 j、区(Secondary Component Carrier/Cell, 简称 为 SCC/SCell)的概念,在进行了载波聚合的系统中, 至少包含一个主服务小区和辅服务小区, 其中, 主服务小区一直处于激活状态。 对于 LTE-A 的终端而言, 如果最多支持 4 比特 ACK/NACK应答信息, 则使用 format lb with channel selection发送 ACK/NACK应答信息; 如 果支持大于 4比特 ACK/NACK应答信息, 则可以使用 format lb with channel selection发送 ACK/NACK应答信息, 也可以使用新引入的 PUCCH format3发送 ACK/NACK应答信息, 具 体使用哪种方式发送 ACK/NACK应答信息通过高层信令进行配置。
空间正交资源传输分集 ( Space Orthogonal-Resource Transmit Diversity, 简称为 SORTD) 是目前多天线系统下 PUCCH formatl/la/lb, format2/2a/2b和 format3的发射分集方案, SORTD 的原理是使用不同的正交资源在不同的天线上传输相同的信令, 对于信道选择来说, 由于使 用的正交资源个数成倍的增加, 所以在 Rel-10的版本中不支持在不同的天线上传输相同的信 令。 在后续版本中, 对于 FDD系统, 最多使用 4个 PUCCH资源在多天线模式下进行传输, 对于 TDD系统, 现在还无法实现信道选择在多天线模式下进行传输的问题。
针对上述的问题, 目前尚未提出有效的解决方案。 发明内容 本发明提供了一种上行控制信息的发送方法和装置, 以至少解决现有技术中无法实现 TDD系统下信道选择在多天线模式下进行传输的技术问题。
