Description

传输信息的方法、 基站和用户设备 技术领域
本发明的实施例涉及通信系统, 尤其是涉及一种传输信息的方法、 基站 和用户设备。 背景技术
与以往的通信系统相比, 第四代移动通信系统可以提供更高的峰值用户 吞吐率、平均用户吞吐率和边缘用户吞吐率,给予用户更佳的数据传输体验。
协作多点传输( Coordinated Multiple Point transmission, CoMP )是为了 获得更高的用户吞吐量而引入第四代移动通信系统的。 CoMP技术是指多个 地理位置相互独立分散的传输点通过不同的协作方式(例如, 联合传输、 联 合处理、 协作调度等)为用户设备提供服务。 其中, 传输点可以是具有完整 资源管理功能、 基带处理功能和射频功能的基站, 或者是地理位置互异的多 个射频单元及天线(例如, 分布式天线), 或者是中继节点。
在 CoMP技术中, 提供了一种动态小区选择方案 (DPS ), 即一个用户 设备在多个小区或节点(或传输点)之间进行动态切换, 而多个小区或节点 以时分方式或频分方式为一个用户设备提供数据传输服务。
在时分方式下, 两个服务节点可以在不同的子帧内为同一个用户设备提 供服务, 在频分方式下, 两个服务节点(传输点)在同一子帧内在不同的资 源 (例如, 频带)上为同一个用户设备提供服务。

下面将结合本发明实施例中的附图,对本发明实施例中的技术方案进行 清楚、 完整地描述, 显然, 所描述的实施例是本发明一部分实施例, 而不是 全部的实施例。 基于本发明中的实施例, 本领域普通技术人员在没有作出创 造性劳动前提下所获得的所有其他实施例, 都属于本发明保护的范围。
应理解, 本发明的技术方案可以应用于各种通信系统, 例如: GSM ( Global System of Mobile communication,全球移动通讯)系统、 CDMA( Code Division Multiple Access ,码分多址 )系统、 WCDMA( , Wideband Code Division Multiple Access, 宽带码分多址)系统、 GPRS ( General Packet Radio Service , 通用分组无线业务)、 LTE ( Long Term Evolution, 长期演进) 系统、 LTE-A ( Advanced long term evolution, 先进的长期演进) 系统、 UMTS ( Universal Mobile Telecommunication System, 通用移动通信系统)等, 本发明实施例并 不限定, 但为描述方便, 本发明实施例将以 LTE网络为例进行说明。 系统中可包括不同的网元。例如, LTE和 LTE-A中无线接入网络的网元包括 eNB ( eNodeB , 演进型基站), WCDMA 中无线接入网络的网元包括 RNC ( Radio Network Controller, 无线网络控制器)和 NodeB , 类似地, WiMax ( Worldwide Interoperability for Microwave Access, 全球微波互联接入 )等其 它无线网络也可以使用与本发明实施例类似的方案, 只 ^^站系统中的相关 模块可能有所不同, 本发明实施例并不限定, 但为描述方便, 下述实施例将 以 eNodeB为例进行说明。
还应理解, 在本发明实施例中, 用户设备( UE, User Equipment ) 包括 但不限于移动台 (MS , Mobile Station )、 移动终端( Mobile Terminal )、 移动 电话 ( Mobile Telephone )、 手机 ( handset )及便携设备 ( portable equipment ) 等, 该用户设备可以经无线接入网(RAN, Radio Access Network )与一个或 多个核心网进行通信, 例如, 用户设备可以是移动电话(或称为 "蜂窝" 电 话)、 具有无线通信功能的计算机等, 用户设备还可以是便携式、 袖珍式、 手持式、 计算机内置的或者车载的移动装置。
在 CoMP技术中, 网络侧设备可以通过高层信令( higher layer signaling ) 为用户设备配置 4个参数集合, 例如, 每个参数集合可以包括如下参数: 针 对 PDSCH 资源单元映射的公共参考信号 (Cell-specific Reference signal, CRS ) 天线端口的编号 ( Number of CRS antenna ports for PDSCH RE mapping ), 针对 PDSCH 资源单元映射的 CRS频率偏移 ( frequency shift )、 针对 PDSCH资源单元映射的 MBSFN子帧配置( subframe configuration )、 针对 PDSCH资源单元映射的零功率 (Zero-power ) CSI-RS资源配置、 针对 PDSCH资源单元映射的 PDSCH开始位置( starting position )、 针对 PDSCH 资源单元映射的信道状态指示参考信号 (Channel State Information RS , CSI-RS ) 资源酉己置标只 ( resource configuration identity )。
在采用频分方式的 DPS技术下, 由于在一个子帧内有多个节点使用不 同的频带为同一个用户设备提供服务, 就需要信令通知给用户设备具体每个 服务节点上有哪些资源为该用户设备服务, 以及这些资源的 PQI信息是什 么。
图 1是根据本发明一个实施例的传输信息的方法的示意性流程图。 图 1 的方法由网络侧设备(例如, 基站)执行。
110, 在一个子帧内, 网络侧设备向用户设备发送一条下行控制信息, 其中该下行控制信息包括多条资源分配信息和至少一个资源单元映射及准 共址指示符的组合。
下行控制信息例如可以是通过物理下行控制信道(Physical Downlink Control Channel, DPCCH )或增强物理下行控制信道 ( Enhanced PDCCH, E-PDCCH )传输的 DCI format 2D。 资源分配信息例如可以用 DCI format 2D 中的若干个比特(例如, 8比特)来表示, 用于指示用户设备哪些资源 (例 如, PRB )用于传输物理数据共享信道。 资源单元映射及准共址指示符例如 可以用 DCI format 2D中的若干比特(例如, 2比特或 3比特)来表示, 用 于指示哪些天线端口占用的资源单元用于传输参考信号, 即哪些传输点的资 源单元不能用于物理数据共享信道的传输,从而指示用户设备在一个子帧内 在传输点的合适资源单元上解码物理数据共享信道。
例如, 网络侧设备可以通过高层信令, 例如, 无线资源控制 (Radio Resource Control , RRC )信令, 向用户设备提供 RRC配置, 其中 RRC配 置包括资源分配信息与资源单元映射及准共址信息的映射关系或对应关系。 可选地,可以在网络侧设备和用户设备预先配置资源分配信息与资源单元映 射及准共址指示符的映射关系或对应关系。 例如, 用户设备可以根据下行控 制信令中的 PDSCH资源单元映射及准共址指示符 (以下筒称资源单元映射 及准共址指示符) 确定使用哪个参数集合中的 PDSCH 资源单元映射及 PDSCH天线端口准共址信息进行 PDSCH解码。 每个传输点的 PDSCH资源 单元映射及 PDSCH天线端口准共址信息是不同的, 因此, 如果使用不同传 输点资源来联合传输物理数据共享信道, 网络侧设备需要通知用户设备每个 传输点的资源上的 PDSCH资源单元映射及 PDSCH天线端口准共址信息。
120, 该网络侧设备向该用户设备发送该下行控制信息所调度的物理数 据共享信道。
例如, 在 CoMP场景下, 网络侧设备可以通过至少一个传输点联合向用 户设备发送物理数据共享信道。 举例而言, 网络侧设备可以在一个子帧内将 一部分物理数据共享信道的数据直接发送给用户设备, 而在同一个子帧将另 一部分物理数据共享信道的数据通过另一网络侧设备发送给用户设备。换句 话说, 这两部分物理数据共享信道的数据分别占用两个网络侧设备对应的资 源发送, 而用户设备根据下行控制信息分别在两个网络侧设备对应的资源上 接收这两部分物理数据共享信道的数据。
网络侧设备可以在该子帧内传输该物理数据共享信道。根据本发明的实 施例并不限于此, 例如, 在跨子帧调度的场景下, 网络侧设备也可以在另一 子帧内传输该物理数据共享信道。
用户设备根据从网络侧设备接收到的下行控制信息, 并且根据资源分配 信息与资源单元映射及准共址指示符的映射关系或对应关系确定在哪些传 输点的哪些资源上解码物理数据共享信道。每个资源分配信息和资源单元映 射及准共址指示符的组合可以指示一个用于传输物理数据共享信道的传输 点的资源。 多个资源分配信息和资源单元映射及准共址指示符的组合可以分 别指示多个用于传输物理数据共享信道的传输点的资源。 这样, 网络侧设备 可以在一个子帧内, 用一条下行控制信息指示多个用于传输物理数据共享信 道的传输点的资源, 从而能够实现采用频分方式的 DPS技术方案。
本发明的实施例可以在一个子帧内为用户设备提供多条资源分配信息 和至少一个资源单元映射及准共址指示符的组合, 以便为多传输点的资源提 供用于解码物理数据共享信道的下行控制信息,从而能够支持采用频分方式 的 DPS技术方案。
根据本发明的实施例, 该多条资源分配信息承载在该下行控制信息的一 个资源分配域(field ) 中, 该资源分配域包括多个部分, 该多个部分分别用 于承载该多条资源分配信息, 该至少一个资源单元映射及准共址指示符包括 一个资源单元映射及准共址指示符且承载在该下行控制信息的一个资源单 元映射及准共址指示符域中。
例如, 在资源分配域为 8个比特的情况下, 可以将资源分配域分为 4个 部分, 每个部分为 2个比特。 在这种情况下, 在用户设备上配置的资源分配 信息与资源单元映射及准共址指示符的映射关系或对应关系中,每 2个比特 的资源分配信息的取值与资源单元映射及准共址指示符的组合联合指示一 个传输点的资源, 这样, 一条下行控制信息的资源分配域的 4个部分 载的 资源分配信息与资源单元映射及准共址指示符的组合可以指示 4个传输点的 资源。 本明的实施例对每个部分的大小不作限定, 不同部分的比特数可以相 同, 也可以不同, 例如, 在资源分配域为 8个比特的情况下, 也可以将资源 分配域分为大小不等的 4个部分: 一个部分为 1比特, 两个部分为 2比特, 另外一个部分为 3比特, 相应地, 可以分别用下行控制信息中的 1个、 2个、 2个和 3个比特的资源分配信息与资源单元映射及准共址指示符的组合联合 指示 4个传输点的资源。
根据本发明的实施例, 一个完整的资源分配域可以指示系统的整个带宽 的资源分配信息。
根据本发明的实施例, 该多条资源分配信息分别承载在该下行控制信息 的多个资源分配域中,该至少一个资源单元映射及准共址指示符包括一个资 源单元映射及准共址指示符且承载在该下行控制信息的一个资源单元映射 及准共址指示符域中。
例如, 下行控制信息包括 4个资源分配域, 在每个资源分配域为 8个比 特的情况下,在用户设备上配置的资源分配信息与资源单元映射及准共址指 示符的映射关系或对应关系中,每 8个比特的资源分配信息的取值与资源单 元映射及准共址指示符的组合联合指示一个传输点的资源, 这样, 一条下行 控制信息的 4个资源分配域 载的资源分配信息与资源单元映射及准共址指 示符的组合可以指示 4个传输点的资源。 应理解, 本明的实施例对每个资源 分配域的大小不作限定, 不同资源分配域的比特数可以相同, 也可以不同, 相应地,可以分别用下行控制信息中的不同比特数的资源分配信息与资源单 元映射及准共址指示符的组合可以联合指示多个传输点的资源。
根据本发明的实施例, 资源单元映射及准共址指示符用于指示多条资源 分配信息对应的资源单元映射及准共址信息。该多条资源分配信息对应于该 资源单元映射及准共址指示符。 例如, 可以是多条资源分配信息中的每条资 源分配信息与该资源单元映射及准共址指示符相对应或者多条资源分配信 息中的若干条资源分配信息与该资源单元映射及准共址指示符相对应。
根据本发明的实施例, 图 1的方法还包括: 网络侧设备向该用户设备发 送该物理数据共享信道所使用的无线资源控制 RRC配置, 该 RRC配置指示 资源分配信息和资源单元映射及准共址指示符之间的对应关系。
例如, 每个 RRC配置包括一个资源单元映射及准共址指示符与多条资 源分配信息的对应关系,一个资源单元映射及准共址指示符包括多种资源单 元映射及准共址指示符状态,每种多种资源单元映射及准共址指示符状态对 应于多条资源分配信息。
根据本发明的实施例, 该多条资源分配信息承载在该下行控制信息的一 个资源分配域中, 该资源分配域包括多个部分, 该多个部分分别用于 载该 多条资源分配信息, 该至少一个资源单元映射及准共址指示符包括多个资源 单元映射及准共址指示符且分别承载在该下行控制信息的多个资源单元映 射及准共址指示符域中。
例如, 在资源分配域为 8个比特的情况下, 可以将资源分配域分为 4个 部分, 每个部分为 2个比特。 例如, 资源单元映射及准共址指示符域可以为 4个, 每个资源单元映射及准共址指示符域 3个比特。 这样, 一条下行控制 信息的资源分配域的 4个部分 载的资源分配信息可以分别 4个资源单元映 射及准共址指示符的组合以指示 4个传输点的资源。 相应地, 在配置的资源 分配信息与资源单元映射及准共址指示符的映射关系或对应关系中,每 2个 比特的资源分配信息的取值与 3个比特的资源单元映射及准共址指示符的取 值的组合联合指示一个传输点的资源。
根据本发明的实施例, 该多条资源分配信息承载在该下行控制信息的多 个资源分配域中, 该至少一个资源单元映射及准共址指示符包括多个资源单 元映射及准共址指示符且^载在多个资源单元映射及准共址指示符域中。 例如, 下行控制信息包括 4个资源分配域和 4个资源单元映射及准共址 指示符域。 这样, 一条下行控制信息的 4个资源分配域 载的资源分配信息 与资源单元映射及准共址指示符的组合可以指示 4个传输点的资源。相应地, 在每个资源分配域为 8个比特且每个资源单元映射及准共址指示符域为 3个 比特的情况下,在配置的资源分配信息与资源单元映射及准共址指示符的映 射关系或对应关系中,每 8个比特的资源分配信息的取值与 3个比特的资源 单元映射及准共址指示符取值的组合联合指示一个传输点的资源。
根据本发明的实施例, 多个资源单元映射及准共址指示符用于分别指示 多条资源分配信息对应的资源单元映射及准共址信息。该多条资源分配信息 分别对应于该多个资源单元映射及准共址指示符。 例如, 该多条资源分配信 息可以——对应于该多个资源单元映射及准共址指示符。
图 2是根据本发明另一实施例的传输信息的方法的示意性流程图。 图 2 的方法由网络侧设备(例如, 基站)执行。
210,在一个子帧内, 网络侧设备向用户设备发送至少一个 E-PDCCH集 合, 其中该至少一个 E-PDCCH集合的资源单元映射及准共址指示符作为用 于传输物理数据共享信道的资源的资源单元映射及准共址指示符。
220, 该网络侧设备向该用户设备发送该物理数据共享信道。
本发明的实施例可以通过 E-PDCCH集合向用户设备指示与资源分配信 息相对应的资源单元映射及准共址指示符, 由于无需使用专门的下行控制信 息向用户设备通知与资源分配信息相对应的资源单元映射及准共址指示符, 因此, 节省了信令开销, 提高了频谱利用率。 另外, 在 E-PDCCH为多个的 情况下, 能够支持采用频分方式的 DPS技术方案。
根据本发明的实施例, 用于传输物理数据共享信道的资源的资源分配信 息与该至少一个 E-PDCCH集合的资源分配信息相同或部分相同。
可选地, 作为另一实施例, 图 2的方法还包括: 将用于传输物理数据共 享信道的资源分配信息与至少一个 E-PDCCH 集合的资源分配信息进行绑 定, 以便通过至少一个 E-PDCCH集合向用户设备隐式地指示资源的资源单 元映射及准共址指示符。

图 3是根据本发明的另一实施例的传输信息的方法的示意性流程图。 图 3的方法由基站执行。
310, 在一个子帧内, 网络侧设备向用户设备发送一条下行控制信息, 其中下行控制信息包括多个下行解调导频的信息, 多个下行解调导频不是准 共址的, 并且多个下行解调导频的信息与下行控制信息中的多个资源单元映 射及准共址指示符相对应。
320, 网络侧设备向用户设备发送下行控制信息所调度的物理数据共享 信道。
例如, 对应于同一条下行控制信息的不同下行解调导频, 例如, 解调参 考信号 (Demodulation Reference Signal, DMRS )端口 (port ), 可以不是准 共址的, 即该下行控制信息中的下行解调导频可以来自不同的传输点。 在下 行控制信息中, 将下行解调导频和 PQI信息之间建立关联, 即每个下行解调 导频对应于一个 PQI, 使得用户设备可以根据每个下行解调导频对应的 PQI 信息区分来自不同传输点的下行解调导频。
根据本发明的实施例可以在多个下行解调导频不是准共址的情况下,通 过将多个下行解调导频的信息与下行控制信息中的多个资源单元映射及准 共址指示符相对应来区分不同的下行解调导频,从而实现物理共享数据信道 的解调。

RRC配置方法 1 : 可以重新设计 RRC配置表, 增加多个 RA, 例如, 针 对 4个 RA,存在 8个 PQI状态,如表 5所示,其中,其中 PQIl-rl2至 PQI8-rl2 为本发明的实施例定义的 LTE版本 12中的 PQI状态, PQI可以为 3个比特, 每个 RA可以为 8比特。 表 5 Rel-12 PQI RA1 RA2 RA3 RA4 状态表

实施例三
本实施例的资源分配方案 (RA scheme )信息中仅有一条 RA信息, 但 分成了多个部分, 换句话说, DCI包括多个 RA域, 每个 RA域分成了多个 部分, 每个部分承载一部分 RA信息。 一个完整的 RA域能指示整个带宽的 资源分配信息。 DCI包括多个 PQI域, 每个 PQI域承载一个 PQI, RA域的 每个部分承载的 RA信息都有一个对应的 PQI信息。
例如, RA信息被分成 4个部分, RA parti、 RA part 2、 RA part 3和 RA part 4, 对应的 PQI分别为 PQI1、 PQI2、 PQI3和 PQI4。 在这种情况下, 下 行控制信息 DCI Format X3如下所示:

RApart3+PQI3
RApart4+PQI4
实施例四
本实施例的资源分配方案信息 (RA scheme ) 中包括有多条 RA信息。 DCI包括多个 RA域, 每个 RA域承载一条 RA信息。 一个完整的 RA域能 指示整个带宽的资源分配信息。 DCI包括多个 PQI域,每个 PQI域承载多个 PQI。 每个 RA域承载的 RA信息都有一个对应的 PQI信息。
例如,该 DCI中包括 4条 RA信息, RA1、 RA2、 RA3和 RA 4 , DCI Format X4如下所示:
DCI Format X4
RA1+PQI1;

实施例五
在本实施例中, 可以将传输点的 RA与至少一个 E-PDCCH集合( Set ) 绑定, 以便通过至少一个 E-PDCCH集合(Set )向用户设备指示多个传输点 的资源对应的 PQI状态。
具体而言, 可以将传输点的 RA与至少一个 E-PDCCH集合的 RA进行 绑定。 如果 TP1的 RA绑定到 E-PDCCH Setl , 那么与 E-PDCCH Setl中的 资源块( Resource Block, RB )重叠的 RA所指示的 RB就可对应到 TP1。
由于 LTE版本 11的系统中配置了两个至少一个 E-PDCCH集合, 而每 个至少一个 E-PDCCH集合都有一个 RRC配置的 PQI状态。 因此, 如果将 多个传输点的 RA与至少一个 E-PDCCH集合绑定, 则可以隐式通知用户多 个传输点的 RA对应的 PQI状态。
