本发明涉及通信技术领域, 特别涉及一种下行测量导频的配置和发送 方法和装置、 以及下行测量导频的接收和测量方法及装置。 背景技术
在无线通信系统中, 在传输数据的同时, 需要伴随发送导频信号, 用 于信道估计和信道测量。 随着 MIMO技术在无线通信系统中的应用, 为了 利用空间选择性, 需要进一步辨别不同空间信道, 这样, 需要发送多个正 交的导频来识别每个空间信道。 随着技术的进步, 收发信机采用更多的天 线, 需要的导频也越来越多。 在 LTE系统中, 不同天线端口的导频都是全 频带配置, 并且在每个子帧都发送导频, 以完成信道估计和信道测量两个 功能。
但是, 在 LTE-A系统中, 下行支持的天线端口数量增至 8个。 为了防 止导频开销过大, SI阶段已将下行导频分为测量导频和解调导频。 其中, 解调导频是用户专属的, 基于流的结构; 测量导频是小区专属, 基于天线 端口的结构, 在时频域上稀疏分布。 然而, 目前现有技术中还没有如何发 送下行测量导频的方案。 发明内容

本发明提出了 LTE-A系统中的下行测量导频的配置及发送方法, 并且 本发明可根据系统工作需要, 灵活配置下行测量导频, 不仅降低了导频的 开销, 还降低了下行测量导频对 R8用户的影响。
本发明附加的方面和优点将在下面的描述中部分给出, 部分将从下面 的描述中变得明显, 或通过本发明的实践了解到。 附图说明
本发明上述的和 /或附加的方面和优点从下面结合附图对实施例的描 述中将变得明显和容易理解, 其中:
图 1 为根据本发明实施例的下行测量导频的配置和发送方法的流程 图;
图 2A至图 2C为根据本发明一个实施例的下行测量导频周期配置的示 意图;
图 3为根据本发明实施例的下行测量导频的起始子帧配置的示意图; 以及
图 4为根据本发明实施例的配置和发送装置的结构图; 图 5为根据本发明实施例的接收和测量方法的流程图; 以及 图 6为根据本发明实施例的接收和测量装置的示意图。 具体实话方式
下面详细描述本发明的实施例, 所述实施例的示例在附图中示出, 其 中自始至终相同或类似的标号表示相同或类似的元件或具有相同或类似功 能的元件。 下面通过参考附图描述的实施例是示例性的, 仅用于解释本发 明, 而不能解释为对本发明的限制。
本发明主要在于, 在配置 LTE-A系统中下行测量导频时, 根据系统工 作需要, 灵活配置下行测量导频, 不仅降低了导频的开销, 还降低了下行 测量导频对 R8用户的影响。
图 1为根据本发明实施例的下行测量导频的配置和发送方法流程图, 该方法包括以下步骤:
步骤 S101 , 基站配置下行测量导频。 其中基站的下行测量导频的周期 与其他基站的下行测量导频的周期可不一致, 这需要根据基站的自身情况 (如天线端口配置情况或测量需求等) 确定。
例如, 采用不同天线端口配置情况的基站, 可配置不同的下行测量导 频周期。 对于天线端口配置较大 (诸如, 天线端口数量大于等于 4 ) 的情 况, 可配置较小的下行测量导频的周期, 而对于天线端口配置较小的情况, 可配置较大的下行测量导频的周期。
以上是对如何配置下行测量导频的一个概述, 以下将以具体的实施例 对如何配置下行测量导频进行介绍:
实施例一, 可根据天线的端口配置情况, 确定基站下行测量导频的周 期。
图 2A至图 2C为根据本发明一个实施例的下行测量导频周期配置的示 意图。 例如, 如图 2A至图 2C所示, 当天线端口数量为 1或 2时, 下行测 量导频周期为 N1 ; 当天线端口数量为 4时, 下行测量导频周期为 N2; 天 线端口数量为 8时, 下行测量导频周期为 N3 ; 如图 2A至图 2C所示, 可 以是 N3≥N2≥M , 当然在此仅是示意图, 重要的是在于, 如果天线的端口 配置情况不同, 其下行测量导频周期也不相同。 其他天线端口配置情况与 此类似, 在此不再赘述。
实施例二, 可根据小区用户的测量需求配置下行测量导频周期。 通常 根据小区内用户信道的统计信息, 特别是移动速度, 调整下行测量导频的 周期。 图 3为根据本发明一个实施例的下行测量导频周期配置的示意图。 例如, 当小区内用户平均移动速度大于 200km/h时, 下行测量导频的周期 N为 N1 ; 当小区内用户平均移动速度小于 200km/h且大于 20km/h时, 下 行测量导频的周期 N为 N2; 当小区内用户平均移动速度小于 20km/h时, 下行测量导频的周期 N为 N3 ; 如图 3所示, 可以是 N3≥N2≥M , 当然在此 仅是示意图, 重要的是在于, 如果小区内用户的测量需求不同时, 其下行 测量导频的周期也不相同。 其它小区内用户的测量需求与此类似, 在此不 再赘述。
在上述两个实施例中, 配置的下行测量导频的周期是小区专属的。 另 外, 下行测量导频的周期是可配置的, 即对于某种天线端口配置模式, 下 行测量导频的周期有 N个可配置的值选择, 根据具体情况选择其中一个; 或者, 其也可以是默认的, 即下行测量导频的周期是一个确定的值, 该值 可以是唯一的或与天线端口配置——对应的。 下行测量导频的周期是可变 的 , 即根据具体情况(如天线端口配置和 /或用户需求等) 的变化而变化。 或者, 其也可以是固定的。
另外, 可以使所有端口的下行测量导频对应于相同的起始子帧号。 需要说明的是, 在实施例一和实施例二中, 也可以使所有端口的下行 测量导频对应于相同的起始子帧号, 且下行测量导频的起始子帧是小区专 属的。 另外, 下行测量导频的起始子帧号是可配置的, 即对于各个端口或 各组端口或各个小区, 下行测量导频的起始子帧有 N个值可以选择; 或者, 其也可以是默认的, 即小区 ID 和 /或双工模式等与下行测量导频的起始子 帧号——对应。
另外, 在上述这些实施例中, 下行测量导频的周期和起始子帧号的配 置应当尽量避免与 PBCH/P-SCH/S-SCH等信道的碰撞。
步骤 S102, 基站将下行测量导频的配置信息发送给 UE, 其中配置信 息包括下行测量导频的起始子帧号和 /或周期。
在该实施例中, 可通过广播或者高层信令将配置信息发送给 UE。 作为 本发明的一个实施例, 可采用对下行测量导频的起始子帧号和 /或周期联合 标识或分别标识的信令将下行测量导频的配置信息发送给 UE,即可以采用 联合编码, 联合标识下行测量导频的起始子帧和 /或周期; 或还可以分别设 定信令指示下行测量导频的起始子帧和 /或周期。
步骤 S103 , 基站按照所述下行测量导频的配置信息将所述下行测量导 频发送给 UE, UE根据下行测量导频的配置信息进行信道测量并反馈信道 状态信息 (如 CSI, CQI/PMI/RI等) 。 其中, 某一个端口的信道状态信息 在导频配置周期内看作是恒定的。
图 4为根据本发明实施例的配置和发送装置的结构图。 该配置和发送 装置 400位于基站侧, 如图 4所示, 其包括配置模块 402和发送模块 404。 配置模块 402用于配置下行测量导频, 包括配置下行测量导频的起始子帧 号和 /或周期, 其中根据所述基站的自身情况(如天线端口配置情况或小区 用户的测量需求等) 确定下行测量导频的周期; 发送模块 404用于将下行 测量导频的配置信息发送给 UE,该配置信息包括下行测量导频的起始子帧 号和 /或周期。
作为本发明的一个实施例, 配置模块 402根据基站的天线端口配置情 况确定下行测量导频的周期, 其中不同的天线端口配置情况对应不同的下 行测量导频的周期。
作为本发明的另一个实施例, 配置模块 402根据小区用户的测量需求 确定下行测量导频的周期。
其中, 在上述实施例中, 下行测量导频的周期可以是小区专属的。 另 外, 下行测量导频的周期可以是配置的或是固定的。
作为本发明的另一个实施例, 配置模块 402根据天线端口配置情况确 定下行测量导频的起始子帧号, 其中, 可以使所有端口的下行测量导频对 应于相同的起始子帧号。 在该实施例中, 下行测量导频的起始子帧号是小 区专属的。 另外, 下行测量导频的起始子帧号是可配置的, 或是固定的。
作为本发明的另一个实施例, 发送模块 404采用对下行测量导频的起 始子帧号和 /或周期联合标识或分别标识的信令将下行测量导频的配置信 息发送给 UE。
图 5为根据本发明实施例的接收和测量方法的流程图。 如图 6所示, 接收和测量方法包括以下步骤:
S502 , UE接收来自基站的下行测量导频的配置信息, 其中, 所述配置 信息包括下行测量导频的起始子帧号和 /或周期; 以及
S504 , UE根据所述配置信息获得下行测量导频并进行信道测量。 图 6为根据本发明实施例的接收和测量装置的示意图。 如图 6所示, 接收和测量装置 600 , 位于 UE侧, 其包括:
所述接收模块 602 , 用于接收来自基站的下行测量导频的配置信息, 其中, 所述配置信息包括下行测量导频的起始子帧号和 /或周期; 以及
所述测量模块 604 , 用于根据所述配置信息获得下行测量导频并进行 信道测量。
在本发明的实施例中, 小区专属包括两层含义:
1、 小区内所有用户的配置是相同的;
2、 不同小区的配置可以相同也可以不同。 小区可以独立完成该配置, 但是考虑到系统性能等因素, 实际中也可以考虑其他小区的配置情况进行 配置。
本发明提出了 LTE-A系统中下行测量导频的配置及发送方法, 并且本 发明可根据系统工作需要, 灵活配置下行测量导频, 从而不仅降低了导频 的开销, 还降低了下行测量导频对 R8用户的影响。
尽管已经示出和描述了本发明的实施例, 对于本领域的普通技术人员 而言, 可以理解在不脱离本发明的原理和精神的情况下可以对这些实施例 进行多种变化、 修改、 替换和变型, 本发明的范围由所附权利要求及其等 同限定。
