Description

天线相关上行反馈方法 技术领域
本发明涉及移动通信领域, 更具体地, 涉及一种天线相关上行反馈 方法。 背景技术
与 3GPP (笫三代伙伴合作计划) LTE (长期演进) Release 8相比, 3GPP LTE Release 10对 UE上行反馈提出了一些新的要求:
· 具有较高秩( rank )的 UE通常安装有较多的接收天线和 较少的发射天线;
- 侦听参考信号( SRS )起到更为重要的作用, 这可能导致 潜在的 SRS资源短缺;
- 针对多用户多输入多输出 ( MU-MIM0 )进行优化 , 例如, 利用信道信息等多种参数。 根据上述演进特点,以下三个因素将成为应用天线相关上行反馈方 案的主要原因:
- UE能力的不对称性一一个 UE通常安装有较多的接收模块 和较少的发射模块;
■ 资源限制一已经提出了一些方案来解决 SRS 资源短缺的 问题, 例如, 非周期 SRS、 将预编码矩阵索引和 /或解调 参考信号(PMI/DMRS )用作 SRS 的补充等; 天线相关上 行反馈方案可以与这些方案进行组合,以提供更高的 SRS 传输效率;
- 灵活的信道状态信息( CSI )反馈精度一无论是基于互易 性的解决方案 (SRS、 上行 /下行转换等)还是基于量化 的解决方案(长期 PMI、 显式协方差矩阵等) , 天线相关 上行反馈方案都能提供更为灵活的反馈精度; 例如, 可 以针对优选的天线 (例如, 具有较好的信道质量指示 ( CQI ) 的天线、 具有较好的空间相关协方差的天线等) 传输更多的上行反馈, 以作为开销和性能之间的折中。 发明内容
考虑到 3GPP LTE Release 10对天线相关上行反馈方案的需求, 本 发明提出了一种天线相关上行反馈方法。 根据本发明, 提出了一种天线相关上行反馈方法, 包括: 基站向用 户设备通知针对指定的天线进行指定形式的上行信息反馈; 用户设备针 对所述指定的天线向基站进行所述指定形式的上行信息反馈。
一方面, 基站可以以隐式形式向用户设备通知所述指定的天线。 优选地, 基站以交替指定的方式指定所述指定的天线, 其中在现有 的控制信令中增加或重新定义一个标志比特, 以指示用户设备采用交替 指定的方式。 或者, 基站以交替指定的方式指定所述指定的天线, 其中 基站通过高层信令指示用户设备采用交替指定的方式。
优选地, 基站以固定指定的方式指定所述指定的天线, 其中基站通 过高层信令指示用户设备采用固定指定的方式。
另一方面, 基站也可以以显式形式向用户设备通知所述指定的天 线。
优选地, 基站以逐比特指定的方式指定所述指定的天线, 其中每个 比特代表一根对应的天线。
优选地, 基站以预定义指定的方式指定所述指定的天线, 其中每个 预定义编码与所有可能的天线相关上行反馈场景中的每一种一一对应。
在本发明中,用户设备向基站反馈的所述指定形式的上行信息包含 以下信息中的至少一项:
- 侦听参考信号 (SRS ) ;
- 量化协方差矩阵;
• 短期预编码矩阵索引 (Short-Term PMI ); 和
• 长期预编码矩阵索引 ( Long-Term PMI ) 。
所述指定的天线是由基站自行确定的。 或者,在基站向用户设备通知针对指定的天线进行指定形式的上行 信息反馈之前, 根据本发明的天线相关上行反馈方法还包括: 用户设备 向基站发送天线 /用户设备相关信息; 在这种情况下, 基站也可以根据 所接收到的天线 /用户设备相关信息, 确定所述指定的天线。
在本发明中, 所述天线 /用户设备相关信息包括以下信息中的至少 一项:
- 天线排列类型;
- 天线间距离;
- 天线特性;
· 用户设备的能力。
所述天线排列类型可以包括: 天线是线阵列天线、 柱状天线阵、 还 是天线方阵。
所述天线特性可以包括: 天线是全向天线, 还是定向天线; 和 /或 天线是极化天线, 还是非极化天线。
所述用户设备的能力可以包括: 用户设备的发送模块的数量、 和 / 或接收模块的数量。 本发明提出了一种灵活的天线相关上行反馈方案,能够在开销和性 能之间提供很好的灵活性。
本发明的优点在于:
( 1 )基站可以通过调度, 减少携带较少信息量的天线反馈信息的 发送次数和 /或所占用资源, 增加携带较多信息量的天线反馈信息的发 送次数和 /或所占用资源; 有效地节省了上行反馈开销, 同时可以确保 性能的损失在可接受的范围以内;
( 2 )考虑到和 3GPP LTE Rel ease 8系统的兼容性, 本发明可以有 效地解决 3GPP LTE Release 8 系统中上行反馈资源短缺的问题, 所述 资源包括侦听参考符号 (SRS ) 、 物理上行控制信道(PUCCH )等。 附图说明
根据以下结合附图对本发明非限制实施例的详细描述,本发明的以 上和其他目的、 特征和优点将变得更加清楚, 其中:
图 1是示出了根据本发明的天线相关上行反馈方法的时序图。 具体实施方式
下面, 将才艮据附图描述本发明。 在以下描述中, 一些具体的实施例 只用于描述的目的, 不应该将其理解为对于本发明的任何限制, 而只是 示例。当可能导致使本发明的理解发生模糊时,将省略传统结构或构造。 图 1是示出了根据本发明的天线相关上行反馈方法的时序图。
在步驟 200, 基站 (eNB ) 可以采用隐式或显式的方式来通知用户 设备 ( UE )针对哪根或哪些根天线进行天线相关上行反馈。
( 1 ) 隐式指定
( a ) 交替指定, 也可以称为轮询指定, 即轮流针对各根 /各组天线来进行上行反馈。 交替指定可以是顺序指定, 也可 以是非顺序指定。 例如, 可以指定具有八根天线的 UE按照针 对天线 1、 针对天线 2 针对天线 8的顺序进行上行反馈
(即每次反馈一根天线的信息); 也可以指定具有八根天线的 UE按照针对天线 3和天线 4、 针对天线 1和天线 2和天线 7、 针对天线 5和天线 6和天线 8的顺序进行上行反馈 (依次同时 反馈两根、 三根、 三根天线的信息) 。
交替指定能够节约上行资源 (如 SRS等) , 和 /或能够以 相同的开销代价, 获得更高的分辨率(如 CS I量化等) 。
有两种隐式指定的办法, 一种是在现有的控制信令基础 上增加或重新定义一个标志比特, 以指示用户设备交替发送。
另一种方法是定义新的反馈模式 (由基站通过高层信令 通知用户设备), 一旦用户被配置了该种反馈模式, 则自动进 入交替反馈状态。
( b ) 固定指定, 可以固定地指定哪根或哪些根天线进行 上行反馈。例如,具有八根天线的 UE的天线 1 ~ 5配置了接收 模块, 天线 6 ~ 8配置了发射模块; 在这种情况下, 可以固定 地指定针对天线 6 ~ 8进行一些指定形式的上行信息的反馈, 例如 SRS等, 而针对天线 1 ~ 5进行另外一些指定形式的上行 信息的反馈, 例如 PMI等。
固定指定尤其适用于非对称发射 /接收配置。
为了支持该隐式指定, 新的反馈模式需要被定义, 一旦 用户设备被指定了该种反馈模式,则用户设备自动按照双方预 定义的机制进行反馈。 另外,新的用户设备能力可能也需要定 义并通知基站, 比如, 该用户设备的 6根天线具有接收模块, 2根天线具有发送模块等。
显示指定
( a )逐比特指定, 可以以比特的形式表示不同的天线, 每个比特的数值指示对应的天线是否被指定。例如, 具有八根 天线的 UE的天线 1一 8分别对应于 8个比特,当天线指定指示 为 "00100100" 时, 针对天线 3和天线 6进行上行反馈; 而当 天线指定指示为 "10101001" 时, 针对天线 1、 天线 3、 天线 5和天线 8进行上行反馈。
逐比特指示能够提供最大的灵活性, 可以实现天线 /天线 组合的任意指定, 当然其代价是相对较高的比特开销。
( b )预定义指定, 对于预定义指定而言, 需要对所有的 天线相关上行反馈场景进行预先定义和编码,从而以相应的信 息比特来表示特定的预定义场景。例如,对于具有八根天线的 UE (天线 1 ~ 8 ) , 所有的天线相关上行反馈场景可以被编码 为: 预定义编码 天线相关上行反馈场景
00 针对天线 1和天线 3进行上行反馈
01 针对天线 2和天线 6进行上行反馈
10 针对天线 2进行上行反馈
11 针对天线 8进行上行反馈 这样, eNB就可以用两个比特的天线指定指示来通知 UE 需要哪根 /哪些根天线进行上行反馈, 由此, 能够节约信息比 特开销。 在步骤 300 , UE针对指定的天线进行上行反馈。 UE需要反馈的、 指定的天线的信息应包含以下信息中的至少一项:
- 侦听参考信号 (SRS ) ;
- 量化协方差矩阵;
- 短期预编码矩阵索引 (Shor t- Term PMI ) ; 和
· 长期预编码矩阵索引 (Long- Term PMI ) 。 在以上的操作中, 需要进行上行反馈的天线完全由 eNB 自行指定 / 保持 /改变。 可选地, 根据本发明的天线相关上行反馈方法还可以包括 步骤 100 (以虚线示出) , UE向 eNB发送天线相关信息。 此时, eNB可 以根据来自 UE的指示 /信息, 进行优选天线 /天线组的选择。 来自 UE的 指示 /信息可以包括以下信息中的至少一项:
- UE的天线排列类型, 例如, 线阵排列、 柱状排列、 方形排列 等;
- UE的天线间距离;
· UE的天线特性, 例如, 全向 /定向天线、 极化与否等;
- UE的能力, 例如, 发射模块的数量、 接收模块的数量等。 eNB可以利用天线排列类型和天线之间的距离估计 UE的各根天线 间的空间相关性, 从而对上行反馈进行天线相关的调度。 例如, 相互距 离较大的天线的协方差矩阵值应当比相互距离较小的天线的协方差矩 阵值更不频繁地被反馈。 eNB甚至可以根据 UE的天线排列类型和抵达方 向 (DoA )粗略地得到 UE的协方差天线矩阵。
UE 的天线特性可以包含以下判断中的至少一项, 例如: 是全向天 线, 还是定向天线; 是极化天线, 还是非极化天线等。 eNB也可以根据 这些信息, 估计出 UE的各根天线间的空间相关性, 从而对上行反馈进 行天线相关的调度。 PO 2011/097753 以上实施例只是用于示例目的, 并不倾向于限制本发明。 本领域普 通技术人员应该理解的是, 在不脱离本发明的范围和精神的情况下, 可 以存在对该实施例的各种修改和代替, 并且这些修改和代替落在所附权 利要求所限定的范围中。
