Description

信道质量指示反馈方法、 资源调度信息发送方法和装置 技术领域
本发明实施例涉及通信技术领域,尤其涉及一种信道质量指示反馈方法、 资源调度信息发送方法和装置。 背景技术
多入多出 (Multiple Input Multiple Output, MIMO)天线技术是无线通信 中的关键技术, 通过发射波束赋形(Beamforming, BF) /预编码和接收合并, MIMO无线系统可以得到分集和阵列增益。 发射波束赋形或预编码需要使用 预编码矩阵, 为了获得最优的预编码矩阵, 发射端需要完全知道信道状态信 息 (Channel State Information, CSI) , 这就需要接收端对瞬时 CSI进行量化 并反馈给发射端, 这种 MIMO系统称为闭环 MIMO系统。
对于闭环 MIMO系统而言, 接收端向发射端反馈的 CSI包括信道质量指 示 (Channel Quality Indicator, CQI) 、 预编码矩阵指示 (Precoding Matrix Indicator, PMI) 、 秩指示 (Rank Indicator, RI) 等信息。 接收端在物理上行 控制信道 (Physical Uplink Control Channel, PUCCH) 或无理上行共享信道 (Physical Uplink Share Channel, PUSCH) 上反馈 CQI时, 有各种的反馈模 式, 对于一种反馈模式来说, 对给定的系统带宽, 子带的 CQI对反馈粒度是 固定的。
但当 MIMO系统的天线端口数量较多时, 例如大规模 MIMO (Massive MIMO) , 天线数量越多, 经过预编码后, 信道质量的频率选择性越小, 当 天线数量很多时, 信道质量在频率上呈现出接近平坦的特性。 而现有的固定 反馈粒度的 CQI反馈方式, 没有利用上述特性, 从而增加系统开销。 发明内容

利用 BF或预编码的典型 MIMO系统通常可以表示为: y = HVs + n, 其 中 y表示接收信号矢量, H表示信道矩阵, V表示预编码矩阵, s表示发射的 符号矢量, n表示测量噪声。 从上式可知, 发射端若要实现最优的传输, 需 要得到最优的预编码矩阵。 而最优预编码通常需要发射端完全已知 CSI才能 得出。
在目前的闭环 MIMO系统中, 常用的 CSI 反馈方法为用户设备 (User
Equipment, UE) 对瞬时 CSI进行量化并反馈给节点 B (NodeB ) , 这里的 NodeB包括任一种形式的基站 (Base Station, BS ) 。 UE需要反馈给 NodeB 的 CSI包括 RI、 PMI、 CQI等信息, 其中 RI和 PMI分别指示使用的层数和 预编码矩阵。 当 RI 2 时, NodeB 发送数据时, 使用两个信道编码的码字 (Codeword) 进行发送。 同样, 当 UE反馈 RI 2的 CQI时, 需要反馈两个 码字的 CQI。当 UE在 PUCCH或 PUSCH上反馈 CQI时,有各种的反馈模式, 例如 PUCCH反馈模式 1-1、 PUCCH反馈模式 2-1。
对于一种反馈模式来说, 对于给定的系统带宽, 子带的 CQI的反馈粒度 是固定的。 CQI 的反馈粒度表示反馈的 CQI 所代表的子带的大小。 例如 PUCCH反馈模式 2-1, 子带的 CQI反馈粒度如表 1所示。
表 1 PUSCH反馈模式 3-1下下行系统带宽和子带大小的关系

在表 1中,下行系统带宽和子带大小都是以资源块(Resource Block, RB ) 为单位。 当系统带宽和子带大小不是整除的关系时, 最后一个子带的大小为
Figure imgf000011_0001
为了提高无线通信系统的性能, 天线端口数量越来越多, 比如在 Massive
MIMO的情况下, 信道的特性会发生变化。 当天线端口数量增加时, 需要表 示的码本就会变多, 经过预编码后, 信道质量的频率选择性越小, 当天线数 量很多时, 信道质量在频率上呈现出接近平坦的特性, 同样比特的 CQI表示 较多子带时性能基本一致。但现有的 CQI反馈模式下, 反馈的 CQI表示的子 带大小相对于系统带宽是固定的, 这样在天线端口数量较多的情况下, 子带 CQI所反馈的比特数没有利用天线端口与信道质量的上述特性, 从而增加系 统开销。
本发明实施例提供一种信道质量指示反馈方法和装置, 应用于 MIMO无 线通信系统, 根据 MIMO系统的天线端口数量确定 CQI的反馈粒度, 从而减 少反馈 CQI所需的比特数。
图 1为本发明实施例提供的信道质量指示反馈装置实施例一的结构示意 图, 如图 1所示, 本实施例的信道质量指示反馈装置包括:
确定模块 11, 用于根据系统带宽、 CQI反馈模式和网络设备设置的天线 端口数量信息确定 CQI的反馈粒度。
具体地, 本实施例提供的信道质量指示反馈装置位于 UE侧, 可以设置 于 UE中。 本实施例提供的信道质量指示反馈装置用于向网络中的网络设备 反馈 CQI, 其中网络设备为网络中的接入设备, 例如各种类型的基站、 演进 型节点 B (Evolved Node B, eNodeB ) 等。
现有的 CQI反馈方法中, 确定模块 11根据系统带宽和 CQI反馈模式确 定 CQI反馈粒度, CQI的反馈粒度表示 CQI所反馈的信息的内容大小, 例如 CQI的反馈粒度包括 UE反馈的 CQI所代表的子带的大小, 即 CQI对应的频 率宽度的大小。不同的 CQI反馈模式下, 相应的系统带宽对应的 CQI的子带 大小是确定的, 因此 UE 的反馈粒度也是确定的。 在本实施例中, 确定模块 11在根据系统带宽和 CQI反馈模式的基础上, 进一步地根据 UE所接入的网 络设备设置的天线端口数量信息确定 CQI的反馈粒度。 例如, 如表 2和表 3 所示, 当 UE所接入的网络设备设置的天线端口数量小于^时, 下行系统带 宽和 CQI的子带大小的关系如表 2所示, 当 UE所接入的网络设备设置的天 线端口数量大于等于 时, 下行系统带宽和 CQI 的子带大小的关系如表 3 所示。 需要说明的是, 表 2和表 3所示的对应关系中, CQI的反馈模式相同。
表 2 天线端口数量小于 时下行系统带宽和 CQI的子带大小的关系
Figure imgf000012_0001
在表 2和表 3中, 下行系统带宽和 CQI的子带大小都是以 RB为单位。 从表 2和表 3中可以看出, 在确定的 CQI反馈模式下, 下行系统带宽相同的 情况下,网络设备设置的天线端口数量较大则相应地 CQI的子带大小也较大。 依据上述设置, 确定模块 11可以在确定下行系统带宽和 CQI反馈模式的基 础上, 根据网络设备设置的天线端口数量信息确定不同的 CQI的子带大小, 天线端口数量越多, 贝 ij CQI的子带大小越大, 该 CQI的子带大小即为 UE确 定的 CQI反馈粒度。
进一步地,表 2和表 3所示的情况仅示出了天线端口数量小于 和大于 等于 的两种情况, 本实施例提供的信道质量指示反馈装置不限于此。还可 以将天线端口数量分为两个以上的范围区间, 例如天线端口数量小于 Ni、 大 于等于 小于 N2、 大于等于 Nj 三种情况等。 当天线端口数量位于不同的 范围区间时, 相同的 CQI反馈模式和系统带宽下对应不同的 CQI反馈粒度。 总之, 在同样的系统带宽和 CQI反馈模式下, 若网络设备包括至少两种天线 端口数量且每种天线端口数量对应的反馈粒度不同, 则天线端口数量越多反 馈粒度越大。
反馈模块 12, 用于根据所述 CQI 的反馈粒度向所述网络设备反馈所述
CQI。
具体地, 当确定模块 11确定了 CQI反馈粒度后, 反馈模块 12根据该反 馈粒度向 UE接入的网络设备反馈该 CQI, 由于确定模块 11确定的 CQI反馈 粒度不仅根据 CQI反馈模式和系统带宽确定, 还根据网络设备设置的天线端 口数量信息确定, 因此 CQI的反馈粒度充分考虑到了 MIMO系统的特点, 当 MIMO系统的天线端口数量较多时, 例如 Massive MIMO中的大规模天线端 口数量,当天线端口数量增多时,增加 CQI的所反馈的子带大小,即增加 CQI 的反馈粒度, 从而减少 UE反馈 CQI所使用的比特数, 节约系统开销。
另外, 通过本实施例节约的反馈 CQI所使用的比特数可以进一步地用来 发送或反馈另外的信息, 从而可以使现有的 MIMO系统在不增加额外开销的 情况下, 反馈更加丰富的信道参考信号信息。
本实施例, 通过根据系统带宽、 CQI 反馈模式和网络设备设置的天线端 口数量信息确定 CQI的反馈粒度,并使用确定的 CQI反馈粒度向网络设备反 馈 CQI, 从而使 CQI的反馈粒度与网络设备设置的天线端口数量相关, 在网 络设备设置的天线端口数量增加的情况下,可以减少反馈 CQI所需的比特数, 从而减少系统开销。
图 2为本发明实施例提供的信道质量指示反馈装置实施例二的结构示意 图, 如图 2所示, 本实施例的信道质量指示反馈装置在图 1的基础上, 还包 括:
获取模块 21, 用于获取所述网络设备发送的所述系统带宽、所述 CQI反 馈模式和所述网络设备设置的天线端口数量信息。
具体地, 本实施例提供的信道质量指示反馈装置中还包括获取模块 21, 获取模块 21用于获取系统带宽、 CQI反馈模式和网络设备设置的天线端口数 量信息。 由于系统带宽、 CQI 反馈模式和网络设备设置的天线端口数量信息 均是在网络设备侧设置的, 因此获取模块 21 是获取网络设备发送的系统带 宽、 CQI反馈模式和网络设备设置的天线端口数量信息。获取模块 21可以获 取网络设备直接发送的上述各项信息,另外获取模块 21还可以从网络设备发 送的各种信令或信息中间接获取上述各项信息。
图 1和图 2所示实施例中, 网络设备设置的天线端口数量信息可以是网 络设备主动或被动设置的任一种天线端口的数量信息, 只要该天线端口的数 量信息能够被获取模块 21获取到即可。例如网络设备设置的天线端口数量信 息, 包括: 网络设备设置的信道状态信息-参考信号 (Channel State Information-Reference Signal, CSI-RS ) 天线端口数量信息。

接收模块 31, 用于接收 UE反馈的 CQI, 所述 CQI的反馈粒度为所述 UE根据系统带宽、 CQI 反馈模式和网络设备设置的天线端口数量信息确定 的。
具体地, 本实施例提供的信道质量指示接收装置位于网络设备侧, 可以 设置于网络设备中。 本实施例提供的信道质量指示接收装置用于接收 UE反 馈的 CQI,其中网络设备为网络中的接入设备,例如各种类型的基站、 eNodeB 等。
现有的 CQI反馈方法中, UE根据系统带宽和 CQI反馈模式确定 CQI反 馈粒度, CQI的反馈粒度表示 CQI所反馈的信息的内容大小, 例如 CQI的反 馈粒度包括 UE反馈的 CQI所代表的子带的大小, 即 CQI对应的频率宽度的 大小。不同的 CQI反馈模式下, 相应的系统带宽对应的 CQI的子带大小是确 定的, 因此 UE 的反馈粒度也是确定的。 在本实施例中, 接收模块 31 接收 UE反馈的 CQI, 所述 CQI的反馈粒度为所述 UE根据系统带宽、 CQI反馈模 式和网络设备设置的天线端口数量信息确定的。也就是说, 接收模块 31接收 到的 UE反馈的 CQI的反馈粒度是 UE根据系统带宽和 CQI反馈模式的基础 上, 进一步地根据网络设备设置的天线端口数量信息确定的。 网络设备设置 的不同天线端口数量对应的 CQI反馈粒度如表 2和表 3所示, 从表 2和表 3 中可以看出, 在确定的 CQI反馈模式下, 下行系统带宽相同的情况下, 网络 设备设置的天线端口数量较大则相应地 CQI的子带大小也较大,也即 CQI反 馈粒度较大。
进一步地,表 2和表 3所示的情况仅示出了天线端口数量小于 和大于 等于 的两种情况, 本实施例提供的信道质量指示接收装置不限于此。还可 以将天线端口数量分为两个以上的范围区间, 例如天线端口数量小于 Ni、 大 于等于 小于 N2、 大于等于 N 三种情况等。 当天线端口数量位于不同的 范围区间时, 相同的 CQI反馈模式和系统带宽下对应不同的 CQI反馈粒度。 总之, 在同样的系统带宽和 CQI反馈模式下, 若网络设备包括至少两种天线 端口数量且每种天线端口数量对应的反馈粒度不同, 则天线端口数量越多反 馈粒度越大。
由于接收模块 31接收到的 CQI的反馈粒度不仅根据 CQI反馈模式和系 统带宽确定, 还根据网络设备设置的天线端口数量信息确定, 因此 CQI的反 馈粒度充分考虑到了 MIMO系统的特点,当 MIMO系统的天线端口数量较多 时, 例如 Massive MIMO中的大规模天线端口数量, 当天线端口数量增多时, 增加 CQI的所反馈的子带大小, 即增加 CQI的反馈粒度, 从而减少 UE反馈 CQI所使用的比特数, 节约系统开销。
另外, 通过本实施例节约的反馈 CQI所使用的比特数可以进一步地用来 发送或反馈另外的信息, 从而可以使现有的 MIMO系统在不增加额外开销的 情况下, 反馈更加丰富的信道参考信号信息。
本实施例, 通过根据系统带宽、 CQI 反馈模式和网络设备设置的天线端 口数量信息确定 CQI的反馈粒度,并使用确定的 CQI反馈粒度向网络设备反 馈 CQI, 从而使 CQI的反馈粒度与网络设备设置的天线端口数量相关, 在网 络设备设置的天线端口数量增加的情况下,可以减少反馈 CQI所需的比特数, 从而减少系统开销。
图 4为本发明实施例提供的信道质量指示接收装置实施例二的结构示意 图, 如图 4所示, 本实施例的信道质量指示接收装置在图 3的基础上, 还包 括:
发送模块 41, 用于向所述 UE发送所述系统带宽、 所述 CQI反馈模式和 所述网络设备设置的天线端口数量信息。
具体地, 本实施例提供的信道质量指示接收装置中还包括发送模块 41, 发送模块 41用于向 UE发送系统带宽、 CQI反馈模式和网络设备设置的天线 端口数量信息。 由于系统带宽、 CQI 反馈模式和网络设备设置的天线端口数 量信息均是在网络设备侧设置的, 因此发送模块 41需要向 UE发送上述各信 息, UE才能够根据上述信息确定 CQI的反馈粒度, 从而向网络设备反馈相 应的 CQI。发送模块 41可以直接向网络设备发送上述各项信息, 另外发送模 块 41还可以通过各种信令或信息间接地向 UE发送上述各项信息。
图 3和图 4所示实施例中, 网络设备设置的天线端口数量信息可以是网 络设备主动或被动设置的任一种天线端口的数量信息, 只要该天线端口的数 量信息能够通过发送模块 41发送到 UE即可。例如网络设备设置的天线端口 数量信息, 包括: 网络设备设置的 CSI-RS天线端口数量信息。
图 1至图 4所示实施例示出了 UE向网络设备反馈 CQI时, 可以通过网 络设备设置的天线端口数量信息调整 CQI的反馈粒度,从而解决 UE反馈 CQI 所使用的比特数。 而在网络设备侧, 网络设备需要向 UE发送包括载波指示、 资源调度、 功率控制、 传输模式等各种信息, 而各种信息据需要占用一定的 比特, 上述各种信息所使用的比特占用了很大一部分系统开销。
对于闭环 MIMO 系统的下行资源调度, 例如基于解调参考信号
(Demodulation Reference Signal, DMRS ) 解调的 MIMO模式 TM9, 使用类 型 0 (Type O) 或类型 1 (Type 1 ) 的资源分配方式指示 RB的分配, 其中类 型 0使用资源块组 (Resource Block Group, RBG) 的资源分配方式; 类型 1 使用比特位图 (Bitmap) 的资源分配方式。 类型 0和类型 1的资源分配方式 是采用离散的方式进行 RB 资源的分配和调度, 因此可以称为非连续资源调 度方法。 但在长期演进(Long Term Evolution, LTE) 的上行传输中, 存在一 种连续资源调度方式, 上行传输使用连续资源调度方式, 主要目的是降低功 率的峰均比。 连续资源调度方式与非连续资源调度方式相比可以降低控制信 令的比特数。
但经研究发现, 当 MIMO系统的天线端口大于一定数量时, 各信道的频 率选择特性将趋于平稳, 此时若应用连续资源调度方式进行下行资源调度, 可以达到与非连续资源调度方式相同的性能。 因此, 本发明提供一种资源调 度信息发送装置, 基于网络设备设置的天线端口数量信息确定所使用的资源 调度方式, 从而节约资源调度所使用的控制信令的比特数。
图 5为本发明实施例提供的资源调度信息发送装置实施例一的结构示意 图, 如图 5所示, 本实施例的资源调度信息方法装置包括:
确定模块 51, 用于根据网络设备设置的天线端口数量信息确定资源调度 方式。
具体地, 本实施例提供的资源调度信息发送装置位于网络设备侧, 可以 设置于网络设备中。 本实施例提供的资源调度信息发送装置用于向 UE发送 资源调度的信息, 其中网络设备为网络中的接入设备, 例如各种类型的基站、 eNodeB等。
现有的 MIMO系统中下行资源调度采用非连续的资源分配方式, 即通过 RGB或 Bitmap的方式确定下行 RB的分配, 这种方式考虑到信道的特性,一 般能够为各信道分配较优的资源。 但当 MIMO 系统的天线端口增多, 例如 Massive MIMO系统中, 由于天线端口增多独立信道也随之增多,信道的频率 选择特性将趋于平稳, 此时若使用连续资源分配方式分配下行 RB 资源, 信 道性能与使用非连续资源分配方式基本一致。
但对于非连续的资源分配方式而言, 资源调度所使用的比特数为 「Λ^/Ρ 其中 N 表示下行系统带宽, Ρ根据下行系统带宽和子带大小确定 并为整数, 「A / ^表示 N /p上取整。 P的取值与下行系统带宽的关系如表
4所示。
表 4 P与下行系统带宽的关系
Figure imgf000017_0002
而若采用连续资源分配方式, 则资源调度所使用的比特数为 [log2(NR D B L(NR D B L+l)/2)] , 其中 N 表示下行系统带宽, 「log2(NR D B L(A +l)/2) 表示
Figure imgf000017_0001
+l)/2)上取整。 将连续资源分配方式与连续资源分配方式进行比 较可知, 采用连续资源分配方式时资源调度所使用的比特数将小于采用非连 续资源分配方式时资源调度所使用的比特数。 表 5示出不同下行系统带宽下 连续资源调度和非连续资源调度所需使用的比特数。
表 5 不同下行系统带宽下连续资源调度和非连续资源调度所需使用的比特数 下行系统带宽 连续资源调度 非连续资源调度

100 13 25
在表 4和表 5中, 下行系统带宽以 RB为单位, 连续资源调度和非连续 资源调度列中示出所需使用的比特数。 从表 5中可以看出, 当下行系统带宽 越大时, 连续资源调度将比非连续资源调度节约更多的比特数。
因此, 在本实施例提供的资源调度信息发送装置中, 包括确定模块 51, 确定模块 51用于根据网络设备设置的天线端口数量信息确定资源调度方式。 也就是说,确定模块 51根据网络设备所设置的不同天线端口数量确定使用不 同的资源调度方式。 从而在天线端口数量变化时, 在保证资源调度的性能的 基础上, 节约资源调度所使用的比特数。
进一步地, 上述资源调度方式包括连续资源调度方式和非连续资源调度 方式; 确定模块 51, 具体用于若判断所述网络设备设置的天线端口数量大于 预设阈值则确定使用连续资源调度方式;否则确定使用非连续资源调度方式。 在资源调度信息发送装置中预设有天线端口数量的阈值,确定模块 51对网络 设备设置的天线端口数量进行判断, 若大于预设阈值则使用连续资源调度方 式, 否则使用非连续资源调度方式。
发送模块 52, 用于根据所述资源调度方式向 UE发送资源调度信息。 具体地, 当确定模块 51确定了资源调度方式后, 资源调度信息发送装置 中的发送模块 52根据该资源调度方式向 UE发送根据该资源调度方式生成的 资源调度信息。 该资源调度信息以信令的方式发送至 UE, 使 UE根据接收的 资源调度信息在相应的资源上接收下行资源。
本实施例, 通过根据网络设备设置的天线端口数量信息确定资源调度方 式, 并向 UE发送资源调度信息, 在网络设备设置的天线端口数量较多时, 节约发送资源调度信息所使用的比特数, 从而节约了系统开销。
进一步地, 由于 UE在接收资源调度信息时, 需要获知发送该资源调度 信息所使用的比特数,才能够在相应的比特上接收该资源调度信息, 因此 UE 也需要得知网络设备设置的天线端口数量信息。 因此, 发送模块 52, 还用于 向所述 UE发送所述网络设备设置的天线端口数量信息。 UE中也预设有天线 端口数量的阈值, 当 UE获取到网络设备设置的天线端口的数量信息后, 就 可以得知需要接收的资源调度信息所使用的比特数, 从而可以在相应的比特 上接收该资源调度信息。
图 6为本发明实施例提供的资源调度信息发送装置实施例二的结构示意 图, 如图 6所示, 本实施例的资源调度信息方法装置在图 5的基础上, 还包 括:
生成模块 61, 用于若确定模块 51确定使用连续资源调度方式, 生成扩 展的多用户 MIMO配对信息。
具体地, 在图 5所示实施例中, 确定模块 51根据网络设备设置的天线端 口数量信息确定资源调度方式, 若确定模块 51确定使用连续资源调度方式, 则发送资源调度信息所使用的比特数将减少。 在本实施例中, 进一步地, 可 以使用从资源调度信息中节约的比特数向 UE发送另一些更多的信息。 因此 本实施例提供的资源调度信息发送装置还包括生成模块 61, 当确定模块 51 确定使用连续资源调度方式, 生成模块 61生成扩展的多用户 MIMO配对信 息。
在目前的 LTE标准中,最多支持 4层的多用户 MIMCXMulti User MIMO, MU-MIMO ),在 MU-MIMO中,一个用户最多传送两层的数据。当使用 massive MIMO时, MU-MIMO将成为一个主要的场景, 一个用户传输的数据层数将 增加。 这样, 省出的比特可以用于指示额外的多用户 MIMO的配对信息, 即 可以生成扩展的多用户 MIMO配对信息。扩展的多用户 MIMO配对信息表示 信息更加丰富的多用户 MIMO分配信息,相较于现有的多用户 MIMO配对信 息, 扩展的多用户 MIMO配对信息包括更多的信息。 比如, 在 Format 2C格 式中, 天线端口、 扰码标识和层数的 3个比特的含义如表 6所示。

另外, 扩展的多用户 MIMO配对信息不仅可以包括如表 7所示的天线端 口、 扰码标识和层数指示对照表, 还可以包括多用户配对信息, 如表 8所示。

表 8中用 3个比特示出了多用户的配对信息, 其中包括层信息和端口信 息的配对关系。
表 7和表 8仅示出扩展的多用户 MIMO匹配信息的两种情况, 在本实施 例中, 扩展的多用户 MIMO匹配信息不以此为限, 只要是能够表示更多的多 用户 MIMO的相关信息就可以成为是扩展的多用户 MIMO匹配信息。
发送模块 52,还用于向所述 UE发送所述扩展的多用户 MIMO配对信息。 具体地, 本实施例中, 发送模块 52, 还用于向 UE 发送扩展的多用户 MIMO配对信息。 发送模块 52可以使用当确定模块 51确定使用连续资源调 度方式时, 发送资源调度信息所节约的比特发送扩展的多用户 MIMO配对信 息。 从而可以在不增加系统开销的前提下, 向 UE发送更多的多用户 MIMO 配对信息。
进一步地, 图 5和图 6所示实施例中, 确定模块 51可以根据网络设备主 动或被动设置的任一种天线端口数量信息确定资源调度方式, 例如确定模块 51可以根据设置的 CSI天线端口数量信息确定资源调度方式。
图 7为本发明实施例提供的资源调度信息接收装置实施例一的结构示意 图, 如图 7所示, 本实施例的资源调度信息接收装置包括:
确定模块 71, 用于根据网络设备设置的天线端口数量信息确定资源调度 方式。
具体地, 实施例提供的资源调度信息接收装置位于 UE侧, 可以设置于 UE中。本实施例提供的资源调度信息接收装置用于向网络中的网络设备反馈 CQI, 其中网络设备为网络中的接入设备, 例如各种类型的基站、 eNodeB等。
根据图 5所示实施例可知, 网络设备侧的资源调度信息发送装置需要根 据网络设备设置的天线端口数量信息确定资源调度方式, 并根据该资源调度 方式向 UE发送资源调度信息。而 UE为了从相应的比特中获取该资源调度信 息, 同样需要确定网络设备所使用的资源调度方式。 因此在本实施例中, 资 源调度信息接收装置中包括确定模块 71, 确定模块 71根据网络设备设置的 天线端口数量信息确定资源调度方式。确定模块 71确定资源调度信息的方法 与图 5中的确定模块 51相同。
接收模块 72, 用于根据所述资源调度方式接收所述网络设备发送的资源 调度信息。
具体地, 当确定模块 71确定了资源调度方式后, 接收模块 71即可根据 该资源调度方式接收网络设备发送的资源调度信息。 从而使 UE根据该资源 调度信息在相应的资源上接收数据。
本实施例, 通过根据网络设备设置的天线端口数量信息确定资源调度方 式, 并接收网络设备发送资源调度信息, 在网络设备设置的天线端口数量较 多时, 节约发送资源调度信息所使用的比特数, 从而节约了系统开销。
图 8为本发明实施例提供的资源调度信息接收装置实施例二的结构示意 图, 如图 8所示, 本实施例的资源调度信息接收装置在图 7的基础上, 还包 括:
获取模块 81, 用于获取所述网络设备发送的所述网络设备设置的天线端 口数量信息。
具体地, 由于确定模块 71需要根据网络设备设置的天线端口数量信息确 定资源调度方式, 因此资源调度信息接收装置首先需要获取网络设备设置的 天线端口数量信息。 资源调度信息接收装置中的获取模块用于获取所述网络 设备发送的所述网络设备设置的天线端口数量信息。
进一步地, 图 7和图 8所示实施例中, 资源调度方式包括连续资源调度 方式和非连续资源调度方式; 确定模块 71, 具体用于若判断所述网络设备设 置的天线端口数量大于预设阈值则确定使用连续资源调度方式; 否则确定使 用非连续资源调度方式。 在资源调度信息接收装置中预设有天线端口数量的 阈值, 确定模块 71对网络设备设置的天线端口数量进行判断, 若大于预设阈 值则使用连续资源调度方式, 否则使用非连续资源调度方式。
上述连续资源调度方式所使用的比特数为「log2 (NR D BL(A +D/2)],非连续资 源调度方法所使用的比特数为「^\^ / ^ , 其中 N 表示下行系统带宽, P根据 下行系统带宽和子带大小确定并为整数。
进一步地, 图 7和图 8所示实施例中, 若确定模块 71确定使用连续资源 调度方式,接收模块 72,还用于接收所述网络设备发送的扩展的多用户 MIMO 配对信息。 具体地, 由于在图 7和图 8所示实施例中, 若确定模块 71确定使 用连续资源调度方式,则接收模块 72接收到的资源调度信息所使用的比特数 将减少,所以接收模块 72就可以使用节约的比特接收网络设备发送的扩展的 多用户 MIMO配对信息。扩展的多用户 MIMO配对信息表示信息更加丰富的 多用户 MIMO分配信息,相较于现有的多用户 MIMO配对信息,扩展的多用 户 MIMO配对信息包括更多的信息。 如表 6至表 8所示, 节约的比特可以接 收额外的信息。
进一步地, 图 7和图 8所示实施例中, 确定模块 71可以根据网络设备主 动或被动设置的任一种天线端口数量信息确定资源调度方式, 例如确定模块 71可以根据所述网络设备设置的测量 CSI天线端口数量信息确定资源调度方 式。 图 9为本发明实施例提供的信道质量指示反馈方法实施例一的流程图, 如图 9所示, 本实施例的方法包括:
