Description

下行数据的速率匹配方法及装置
技术领域 本发明涉及通信领域, 具体而言, 涉及一种下行数据的速率匹配方法及装置。 背景技术 长期演进(Long Term Evolution, 简称为 LTE)系统在经历了第三代合作伙伴 G"1
Generation Partnership Project, 简称为 3GPP) R8/9/10几个版本后, 又陆续准确地研究 R11版本技术。 目前, 部分 R8版本产品开始逐步商用, R9版本和 R10版本有待进行 进一步的产品规划。 在经历了 R8版本和 R9版本阶段之后, R10版本在前两者的基础上又增加了很多 新的特性, 例如, 解调参考信号 (Demodulation Reference Signal, 简称为 DMRS)、 信 道状态信息参考信号 (Channel State Information Reference Signal, 简称为 CSI-RS) 等 导频特性, 8 天线支持等传输和反馈特性, 特别是小区间干扰抵消增强 (Enhanced Inter-Cell Interference Cancelling, 简称为 elCIC) 技术在考虑了 R8/9版本中 ICIC的基 础之上, 进一步考虑了小区之间的干扰避免技术。 对于解决小区之间干扰问题的技术 而言, 在 R10版本的阶段初期主要考虑了同构网下的小区干扰避免, 其中, 主流技术 考虑了 elCIC技术和多点协作 (Coordinated Multi-point, 简称为 CoMP) 技术, CoMP 是指多个节点协作给一个或者多个 UE在相同的时频资源或者不同的时频资源上发送 数据, 因此, CoMP可以减少小区之间的干扰, 提高小区边缘的吞吐率, 扩大小区覆 盖。 但是, 由于在讨论后期考虑了异构网引入更多场景的情况、 CoMP技术的复杂性, 以及 R10版本的讨论时间限制,最终决定在 R10版本阶段不引入额外的 CoMP标准化 内容, 在设计 CSI-RS时可以考虑 CoMP的部分需求, 因此, CoMP技术在 60bis会议 后就没有进行更深一步的讨论。
LTE定义了物理下行控制信道(Physical downlink control channel,简称为 PDCCH) 承载调度分配和其它控制信息, 每个 PDCCH由若干个控制信道单元(Control Channel Element, 简称为 CCE) 组成, 每个子帧的 CCE数目由 PDCCH的数量和下行带宽决 定。 用户设备 (User Equipment, 简称为 UE) 是通过在搜索空间中进行盲检测得到 PDCCH的,搜索空间分为公共搜索空间和用户专用搜索空间,公共搜索空间是指所有 的 UE都会搜索到的区域, 此空间携带的是小区专有信息; 用户专用搜索空间是单个 UE会搜索到的空间范围, 多个 UE的用户专用搜索空间有可能重叠, 但是每个 UE的 用户专用搜索空间的一般初始搜索位置是不一样的。 在 UE进行盲检测之前, 通常由 基站通过高层信令通知 UE 需要采用的工作模式和用于 PDCCH 的循环冗余校验 (Cyclic Redundancy Check, 简称为 CRC) 加扰的无线网络临时标识 ( Radio Network Temporary Identity, 简称为 RNTI) 类型。 其中, 搜索空间 与聚合级别 L及候选 PDCCH数量 间的关系请参见表 1。 聚合等级即 PDCCH占用的 CCE个数。在 UE在用户专用搜索空间进行盲检测时, UE 首先根据 UE ID (用户标识) 和子帧号等计算出盲检测初始位置 , 然后在用户专用 搜索空间中进行检测, 直到检测到分给自己的 PDCCH为止。 表 1 PDCCH候选集

聚合级别和 PDCCH第一个控制信道单元在用户专用搜索空间中的相对位置及对 应关系请参见表 2。 PDCCH第一个控制信道单元在用户专用搜索空间中的相对位置是 指 PDCCH占用的第一个 CCE的索引 nCCE与盲检测初始位置 的相对位置(本申请 中用 nCCE, offset表示), nCCE, offset= nCCE - 。 如表 2所示, 为用户专用搜索空 间, 可能的第一个 CCE位置及其对应的聚合等级的示意图。 表 2 聚合级别和第一个 CCE位置的对应关系

在有关 LTE技术的最新的第 67次会议讨论过程中, 关于下行控制信令的提案基 本上都是关于 CSI-RS信令增强、 DMRS信令增强、 小区专用参考信号 (Cell-Specific Reference Signal, 简称为 CRS)碰撞与干扰问题避免增强、 PDSCH起始符号对齐接收 增强、 零功率和非零功率的 CSI-RS碰撞和干扰避免增强。 其中, CRS碰撞和干扰问 题避免增强、 PDSCH起始符号对齐接收增强、 零功率和非零功率的 CSI-RS碰撞和干 扰避免增强都属于速率匹配范畴, 统称为干扰避免方法, 具体地, 可以根据通知的信 令来进行速率匹配处理或者干扰压缩处理, 其主要原因在于: 在 R11版本的新增场景 中, 特别是 SCenariol~3, 由于不同的节点所具有的小区标识不同, 导致不同节点的 CRS位置不同,导致不同节点的序列也不同。这时,如果不同节点间进行联合发送 (Joint Transmission, 简称为 JT), 则不同节点的资源合并则无法对齐, 如果按照每个小区的 CRS、 PDSCH起始符号或者零功率 CSI-RS的配置独立进行数据映射,由于 Muting (噪 声抑制) 的资源位置不同会导致数据合并错误, 如果按照主服务节点来进行合并, 导 致资源浪费的同时也引入了其他节点的 CRS对数据的干扰。另外, 对于动态节点选择 (Dynamic Point Selection, 简称为 DPS)来说, 由于不同的子帧会由不同的节点向 UE 发送, 如果按照主服务节点来发送数据同样也存在资源浪费和 CRS 对数据的干扰问 题; 如果考虑利用零功率 CSI-RS测量干扰, 则需要配置更多的零功率 CSI-RS, 如果 配置在一个节点的零功率 CSI-RS子帧的 UE不能意识到零功率 CSI-RS的存在, 可能 会对这种 UE造成较大的影响。 针对相关技术中下行数据速率匹配准确率比较低的问题, 目前尚未提出有效的解 决方案。 发明内容 针对相关技术中下行数据速率匹配准确率比较低的问题, 本发明提供一种下行数 据的速率匹配方法及装置, 以至少解决上述问题。 根据本发明的一个方面, 提供了一种下行数据的速率匹配方法, 包括: 用户设备 UE获取以下信息之一:基站配置的用于指示 UE进行速率匹配的一套或者多套速率匹 配资源指示信息; 所述一套或者多套速率匹配资源指示信息和速率匹配资源组合指示 信息, 其中, 所述速率匹配资源组合指示信息用于指示所述一套或者多套速率匹配资 源指示信息的组合; 所述 UE接入网络时获取的该 UE的服务小区的速率匹配资源指 示信息; 所述 UE确定所述基站发送的下行控制信息的子帧中的下行授权指示信息所 对应的下行控制信息格式 DCI Format;所述 UE根据所述 DCI Format和预设对应关系, 确定所述 DCI Format对应的用于速率匹配的速率匹配资源信息,并根据所述速率匹配 资源信息对下行数据进行速率匹配操作, 其中, 所述预设对应关系包括以下之一: 所 述一套或者多套速率匹配资源指示信息与所述 DCI Format的对应关系、所述服务小区 的速率匹配资源指示信息与所述 DCI Format的对应关系的对应关系、所述速率匹配资 源组合指示信息与所述 DCI Format的对应关系。 优选地, 所述 UE根据所述 DCI Format和预设对应关系, 确定所述 DCI Format 对应的资源信息包括以下之一: 所述下行授权控制信息所对应的 DCI Format为 DCI Format 1A时,所述 UE确定当前子帧采用的速率匹配的资源信息为高层信令配置的第 一套速率匹配资源指示信息或者最低索引的速率匹配资源指示信息。 所述下行授权控 制信息所对应的 DCI Format 为所述 DCI Format 1A时, 所述 UE确定当前子帧采用的 速率匹配的资源信息为所述 UE接入网络时获取的服务小区的速率匹配资源指示信息; 所述下行授权控制信息所对应的 DCI Format 为所述 DCI Format 1 A时, 所述 UE确定 当前子帧采用的速率匹配的资源信息为终端专用高层信令配置的一套速率匹配资源指 示信息; 所述下行授权控制信息所对应的 DCI Format 为所述 DCI Format 1 A时, 所述 UE 通过第一预设资源指示信息指示终端专用高层信令配置的两套速率匹配资源指示 信息中的哪一套为当前子帧的速率匹配的资源信息; 所述下行授权控制信息所对应的 DCI Format为所述 DCI Format 1A时, 所述 UE采用预设状态对应的第二预设资源指 示信息为当前子帧的速率匹配的资源信息, 其中, 所述第二预设资源指示信息的内容 通过所述高层信令通知给所述 UE; 所述下行授权控制信息所对应的 DCI Format 为 DCI Format 2B、 DCI Format 2C或者 DCI Format 2D时, 所述 UE采用第三预设资源指 示信息为所述用于速率匹配的资源信息, 其中, 所述第三预设资源指示信息通过所述 下行授权控制信息中的预设比特来进行指示。 优选地, 所述第一预设资源指示信息通过多播广播单频网络 MBSFN子帧中 DCI
