在 LTE系统(Release-8 ) 的基本传输方案中: FDD ( Frequency division duplex, 频分双工) 系统与 TDD ( Time division duplex, 时分双工) 系统分别 如图 1A和图 1B所示。对于每个工作载波(即上行载波和下行载波), 分别定 义了下行控制信令、 下行数据、 上行控制信令和上行数据, 以及彼此之间的 传输关系。 上行控制信令占用频带的两端, 使用跳频方式传输, 即在一个子 帧内的两个时隙里, 上行控制信令将占用不同的频段传输。
对于长期演进多载波系统, 为支持比长期演进系统更宽的系统带宽, 比 如 100MHz, —种可能是直接分配 100MHz带宽, 其频谱参见图 1C, 一种可 能是将分配给现有系统的一些频语聚合起来, 凑成大带宽供给长期演进多载 波系统使用, 此时系统中上行载波和下行载波可以不对称配置, 即用户可能 会占用 N个下行载波进行下行传输, 占用 M个上行栽波进行上行传输, 且
Ν≠Μ , 参见图 1D。
由于长期演进多载波系统中存在多个载波, 并且上行载波和下行载波有 可以不对称配置, 所以目前的长期演进系统中配置上行控制信令区域的方案 艮难适用于长期演进多载波系统中。
综上所述, 目前的长期演进多载波系统中没有配置上行控制信令区域的 方案。 发明内容

本发明实施例建立上行载波组和下行载波组的对应关系, 并根据上行载 波组和下行载波组的对应关系, 对上行载波组中的每个上行载波配置上行控 制信令区域, 从而在长期演进多载波系统中配置上行控制信令区域, 提高了 上行传输效率。
下面结合说明书附图对本发明实施例作进一步详细描述。
如图 2所示, 本发明实施例资源配置的装置包括: 分组模块 1、 建立模块 2和配置模块 3。
分组模块 1, 用于对上行载波进行分组, 生成至少一个上行载波组, 对多 个下行载波进行分组, 生成下行载波組。
其中, 下行载波组的数量不大于上行载波组的数量。
比如: 有 M个上行载波(M为正整数, 且 M>1), N个下行载波(N为 正整数, 且1^>2)。
将 M个上行栽波分成 m组, 则第 j组中包含 Uj个上行栽波;
其中, l<m<M, Kuj<M, j = 1, 2..... m。
将 N个下行载波分成 n组, 则第 i组中包含 di个下行载波;
其中, l<n<N, JLn<m, Kdi<N, i=l, 2..... n。
比如: 有 5个上行载波, 8个下行载波, 则可以将上行载波分成 3组, 其 中有一组含有 1个上行栽波, 另外两组分别含有两个上行载波;
则可以将下行载波分为 2组, 每组分别含有 4个下行载波。 需要说明的是, 只要保证下行载波组的数量不大于上行载波組的数量, 具体上行载波和下行载波分为多少组, 以及每组中含有多少个上行载波和下 行载波, 可以根据需要进行设定。
建立模块 2, 用于根据分组模块 1生成的上行载波组和下行栽波组, 建立 上行载波组和下行载波组的对应关系。
其中, 每个下行载波组对应至少一个上行载波组。
比如: 有三个上行栽波组 al、 a2和 a3, 以及一个下行载波组 bl, 则建立 的对应关系可以是下行载波组 bl对应上行载波组 al、 a2和 a3。
比如: 有三个上行栽波组 al、 a2和 a3 , 以及三个下行载波组 bl、 b2和 b3, 则建立的对应关系可以是: 下行载波组 bl对应上行载波组 al和 a2, 下 行载波组 b2对应上行载波组 al和 a3, 下行载波组 b3对应上行载波组 a2和 a3。
需要说明的是, 只要保证每个下行载波组都对应至少一个上行载波组, 具体哪个下行载波组对应哪个上行载波组, 可以根据需要进行设定。 个下行载波配置上行控制信令区域。
比如: 一个含有 3个上行载波的上行载波组对应一个含有 5个下行载波 的下行载波组, 则所述 3个上行载波中的每个上行载波都需要配置 5个上行 控制信令区域, 每个上行控制信令区域对应一个下行载波。
如果多个下行载波组对应一个上行载波组, 会减少上行载波组中每个上 行载波的上行数据区域。 较佳地, 如果生成至少两个下行载波组(即上行载 波组也至少是两组), 则可以在建立的上行栽波组和下行载波组的对应关系 中, 使每个下行载波组对应不同的至少一个上行载波组, 这样可以增加上行 数据区域。
比如: 有三个上行载波组 al、 a2和 a3, 以及三个下行载波组 M、 b2和 b3 , 则建立的对应关系可以是: 上行栽波组 al对应下行载波组 M , 上行载波 組 a2对应下行载波组 b2, 上行载波组 a3对应下行载波组 b3 , 这样上行载波 组 al 中的所有上行载波只需要为下行载波组 bl 中的所有下行载波配置上行 控制信令区域即可, 上行载波组 a2和 a3也是如此。
然而, 如果只有一组下行载波组, 则不能采用此方案。
还有一种建立对应关系的方法是在每个下行载波组对应不同的至少一个 上行载波组的前提下, 进一步地, 如果上行载波组的数量大于下行载波组的 数量, 则多余出来的每个上行载波组可以对应多个下行载波组。
比如: 有三个上行载波组 al、 a2和 a3 , 以及两个下行载波组 bl和 b2, 则建立的对应关系可以是:上行载波组 al对应下行栽波组 bl,上行载波组 a2 对应下行载波组 b2, 上行载波组 a3就是多余出来的上行载波组, 则上行载波 组 a3可以对应所有下行载波组, 即上行载波组 a3对应下行载波组 bl和 b2。
在具体实施过程中, 可以不建立多余出来的每个上行载波组和下行栽波 组的对应关系, 默认为如果对应关系中没有上行载波组 A, 则上行载波组 A 与所有下行载波组对应。
当然, 具体采用哪种配置方案可以在协议中进行规定, 这样是为了保证 网络侧和终端侧保持一致。
配置模块 3,用于根据建立模块 2建立的上行载波组和下行载波组的对应 关系, 对上行载波组中的每个上行载波配置上行控制信令区域。
其中, 配置模块 3还可以进一步包括: 下行载波组确定模块 31、 数量确 定模块 32和处理模块 33。
下行载波组确定模块 31, 用于根据建立模块 2建立的上行载波组和下行 载波组的对应关系, 确定上行载波组对应的所有下行载波组。
比如: 有三个上行栽波组 al、 a2和 a3, 以及两个下行载波组 bl和 b2, 建立的对应关系可以是: 上行载波组 al对应下行载波组 bl, 上行载波组 a2 对应下行载波组 b2, 上行载波组 a3对应下行载波组 bl, 上行载波组 a3对应 下行载波组 b2。
则根据建立的对应关系确定上行载波组 al对应的所有下行载波组为下行 载波组 bl; 上行载波组 a2对应的所有下行载波组为下行载波组 b2; 上行载 数量确定模块 32,用于确定下行载波组确定模块 31确定的上行载波组对 应的所有下行载波组中下行载波的数量。
比如: 下行载波组 bl和 b2分别有 3个和 5个下行载波, 则确定上行载 波组 al对应的所有下行载波组中下行载波的数量为 3个;确定上行载波组 a2 对应的所有下行载波组中下行载波的数量为 5个; 确定上行载波组 a3对应的 所有下行载波组中下行载波的数量为 8个。
处理模块 33, 用于对上行载波组中的每个上行载波配置与数量确定模块 32确定的下行栽波的数量相同数量的上行控制信令区域。
其中, 一个上行载波中配置的每个上行控制信令区域与确定的所有下行 载波组中的每个下行载波 对应。
比如: 上行载波组 al对应的所有下行载波组中下行载波的数量为 3个; 上行载波组 a2对应的所有下行载波组中下行载波的数量为 5个; 上行载波组 a3对应的所有下行载波组中下行载波的数量为 8个。
则对上行载波组 al中的每个上行载波配置 3个上行控制信令区域, 与下 行载波组 bl中的 3个下行载波——对应;
对上行载波组 a2中的每个上行载波配置 5个上行控制信令区域, 与下行 载波组 b2中的 5个下行载波 对应;
对上行载波组 a3中的每个上行载波配置 8个上行控制信令区域, 与下行 载波组 M中的 3个下行载波和下行载波组 b2中的 5个下行载波——对应。
这样就完成了对上行控制信令区域的配置。
配置完上行控制信令区域后, 为了让终端知道下行载波对应哪个上行载 波中的上行控制信令区域, 则需要将建立的上行载波组和下行载波组的对应 关系发送给终端, 则本发明实施例资源配置的装置还可以进一步包括: 广播 模块 4。
广播模块 4,用于通过广播信令发送建立模块 2建立的上行载波组和下行 载波组的对应关系。 需要说明的是, 本发明实施例并不局限于通过广播信令发送这一种方式, 任何能够将上行载波组和下行载波組的对应关系发送给终端的方式都适用本 发明实施例。
本发明实施例的资源配置的装置可以是基站, 也可以是其他装置。
如图 3所示, 本发明实施例资源配置的方法包括下列步骤:
步骤 300、 对上行载波进行分组, 生成至少一个上行载波组, 对多个下行 载波进行分组, 生成下行载波组。
其中, 下行载波组的数量不大于上行载波组的数量。
比如: 有 M个上行栽波(M为正整数, 且^1>1), N个下行载波(N为 正整数, 且1^>2)。
将 M个上行载波分成 m组, 则第 j组中包含 uj个上行载波;
其中, : m<M, l<uj<M, j = 1, 2..... m。
将 N个下行载波分成 n组, 则第 i组中包含 φ个下行载波;
其中, l<n<N, JLn<m, Kdi<N, i= 1, 2…-. n。
比如: 有 5个上行载波, 8个下行载波, 则可以将上行载波分成 3组, 其 中有一组含有 1个上行载波, 另外两组分别含有两个上行载波;
则可以将下行载波分为 2组, 每组分别含有 4个下行载波。
需要说明的是, 只要保证下行载波組的数量不大于上行载波组的数量, 具体上行载波和下行载波分为多少组, 以及每组中含有多少个上行载波和下 行载波, 可以根据需要进行设定。
步骤 301、 建立上行栽波组和下行载波组的对应关系。
其中, 每个下行载波组对应至少一个上行栽波组。
比如: 有三个上行载波组 al、 a2和 a3, 以及一个下行载波组 bl, 则建立 的对应关系可以是下行载波组 bl对应上行载波组 al、 a2和 a3。
比如: 有三个上行载波组 al、 a2和 a3, 以及三个下行载波组 bl、 b2和 b3, 则建立的对应关系可以是: 下行载波组 M对应上行载波组 al和 a2, 下 行载波组 b2对应上行载波组 al和 a3, 下行载波组 b3对应上行载波组 a2和 a3。
需要说明的是, 只要保证每个下行载波组都对应至少一个上行载波组, 具体哪个下行载波组对应哪个上行载波组, 可以根据需要进行设定。
个下行载波配置上行控制信令区域。
比如: 一个含有 3个上行载波的上行载波组对应一个含有 5个下行载波 的下行载波组, 则所述 3个上行载波中的每个上行载波都需要配置 5个上行 控制信令区域, 每个上行控制信令区域对应一个下行载波。
如果多个下行载波组对应一个上行载波组, 会减少上行载波组中每个上 行载波的上行数据区域。 较佳地, 如果确定至少两个下行载波组(即上行载 波组也至少是两组), 则可以在建立的上行载波组和下行载波组的对应关系 中, 使每个下行载波组对应不同的至少一个上行载波组, 这样可以增加上行 数据区域。
比如: 有三个上行载波组 al、 a2和 a3 , 以及三个下行载波组 bl、 b2和 b3 , 则建立的对应关系可以是: 上行载波组 al对应下行栽波组 bl , 上行载波 组 a2对应下行载波组 b2, 上行载波组 a3对应下行载波组 b3 , 这样上行载波 组 al 中的所有上行载波只需要为下行载波组 bl 中的所有下行载波配置上行 控制信令区域即可, 上行载波组 a2和 a3也是如此。
然而, 如果只有一组下行载波组, 则不能采用此方案。
还有一种建立对应关系的方法是在每个下行载波组对应不同的至少一个 上行载波组的前提下, 进一步地, 如果上行载波组的数量大于下行载波组的 数量, 则多余出来的每个上行载波组可以对应多个下行载波组。
比如: 有三个上行载波组 al、 a2和 a3, 以及两个下行载波组 bl和 b2, 则建立的对应关系可以是:上行载波组 al对应下行载波组 bl,上行载波组 a2 对应下行载波组 b2, 上行载波组 a3就是多余出来的上行载波组, 则上行载波 组 a3可以对应所有下行载波组, 即上行载波组 a3对应下行载波组 bl和 b2。
在具体实施过程中, 可以不建立多余出来的每个上行载波组和下行载波 组的对应关系, 默认为如果对应关系中没有上行载波组 A, 则上行载波组 A 与所有下行载波组对应。
当然, 具体采用哪种配置方案可以在协议中进行规定, 这样是为了保证 网络侧和终端侧保持一致。
步骤 302、才艮据上行载波组和下行载波组的对应关系,对上行载波组中的 每个上行载波配置上行控制信令区域。
其中, 步骤 302还可以进一步包括:
步骤 a302、 根据上行载波组和下行载波组的对应关系, 确定上行载波组 对应的所有下行载波组。
比如: 有三个上行载波组 al、 a2和 a3 , 以及两个下行载波组 bl和 b2, 建立的对应关系可以是: 上行载波组 al对应下行载波组 M , 上行载波组 a2 对应下行载波组 b2, 上行载波组 a3对应下行载波组 bl , 上行载波组 a3对应 下行载波组 b2。
则根据建立的对应关系确定上行载波组 al对应的所有下行载波组为下行 载波组 bl; 上行载波组 a2对应的所有下行载波组为下行载波组 b2; 上行载 波组 a3对应的所有下行载波组为下行载波组 bl和 b2。
步骤 b302、 确定上行载波组对应的所有下行载波组中下行载波的数量。 比如: 下行载波组 bl和 b2分别有 3个和 5个下行载波, 则确定上行载 波组 al对应的所有下行栽波组中下行载波的数量为 3个;确定上行载波组 a2 对应的所有下行载波组中下行载波的数量为 5个; 确定上行载波组 a3对应的 所有下行载波组中下行载波的数量为 8个。
步骤 c302、 对上行载波组中的每个上行载波配置与确定的下行载波的数 量相同数量的上行控制信令区域。
其中, 一个上行载波中配置的每个上行控制信令区域与确定的所有下行 载波组中的每个下行载波 对应。
比如: 上行载波组 al对应的所有下行载波组中下行载波的数量为 3个; 上行载波组 a2对应的所有下行载波组中下行载波的数量为 5个; 上行载波组 a3对应的所有下行载波组中下行载波的数量为 8个。
则对上行载波组 al中的每个上行载波配置 3个上行控制信令区域, 与下 行载波组 bl中的 3个下行载波——对应;
对上行栽波组 a2中的每个上行载波配置 5个上行控制信令区域, 与下行 载波组 b2中的 5个下行载波——对应;
对上行载波组 a3中的每个上行载波配置 8个上行控制信令区域, 与下行 栽波组 bl中的 3个下行载波和下行载波组 b2中的 5个下行载波 对应。
这样就完成了对上行控制信令区域的配置。
配置完上行控制信令区域后, 为了让终端知道下行载波对应哪个上行载 波中的上行控制信令区域, 则需要将建立的上行载波组和下行载波组的对应 关系发送给终端, 则步骤 301之后还可以进一步包括:
通过广播信令发送建立的上行载波组和下行载波组的对应关系。
需要说明的是, 本发明实施例并不局限于通过广播信令发送这一种方式, 发明实施例。 '
下面以一具体示例对本发明实施例资源配置的方案进行进一步说明。
设系统由 4个下行载波, 4个上行载波聚合而成。
将 4个下行栽波分为 2组, 第一组(
Figure imgf000013_0001
) 由下行载波 1、 2组成, 第二 组(c2 ) 由下行载波 3、 4组成。 将 4个上行载波分为 3组,第一组( CiUL )由上行载波 1组成,第二组( c ) 由上行载波 2组成, 第三组(C^ ) 由上行载波 3、 4组成。
建立 C' 与 ci 对^, c2 与 C3 对 , 则上行载波 1中只为下行载波 1、 2 预留相应的上行控制信令区域, 上行栽波 3、 4中同时为下行栽波 3、 4预留 相应的上行控制信令区域, 而 组中的上行载波 2中将为所有 4个下行载波 预留相应的上行控制信令区域, 参见图 4。 <^ 与<^对应和 C 与 C 对应(对应关系 1 )只是举例说明, 完全可以配 置为 与 对^和 ^ 与<^ 对^ (对 关系 2 )。
在采用对应关系 1时, 上行载波 3和 4分别预留下行载波 3、 4的上行控 制信令区域;
在采用对应关系 2时, 上行载波 3和 4分别预留下行载波 1、 2、 3和 4 的上行控制信令区域。
所以采用对应关系 1相比于采用对应关系 2能够提高上行数据区域; 相 应地, 采用对应关系 2时比采用对应关系 1时的上行控制信令区域多, 所以 终端发送上行控制信令的方式更灵活。
也就是说, 本发明实施例具体上行载波组和下行载波组的对应关系, 可 以根据需要进行设定。
下面描述的本发明实施例的数据传输方案, 除非特殊说明, 否则都是利 用本发明实施例配置的资源进行的数据传输。
如图 5所示, 本发明实施例数据传输的系统包括: 基站 10和终端 20。 基站 10, 用于根据需要发送数据的容量和生成的下行载波组, 确定承载 数据的下行载波, 通过确定的下行载波发送数据。
终端 20, 用于通过下行载波接收来自基站 10的数据。
如图 6所示, 本发明实施例基站包括: 第一载波确定模块 100和第一发 送模块 110。
第一载波确定模块 100,用于根据需要发送数据的容量和生成的下行载波 组, 确定承载数据的下行栽波。
其中, 如果需要三个下行栽波才能承载需要发送数据, 则从生成的下行 载波组中选择三个下行载波。
选择的三个下行载波可以都在同一个下行载波组中, 也可以不在同一个 下行载波组中。
较佳地, 第一载波确定模块 100在一个下行载波组中的下行载波可以承 载需要发送数据时, 从该下行载波组中选择至少一个下行载波。
比如: 有三个下行载波就可以承载需要发送的数据, 则查看是否有包含 至少三个下行载波的下行载波组, 如果有, 则可以从一个下行载波组中选择 三个下行载波; 如果没有, 则从多个下行载波组中选择三个下行载波, 在选 择时可以涉及尽量少的下行载波组, 也就是说, 如果可以从两个下行载波组 中选择三个下行载波, 则不选择三个下行载波组。
第一发送模块 110,用于通过第一载波确定模块 100确定的下行载波发送 数据。
如图 7所示, 本发明实施例终端包括: 第二载波确定模块 200和第二发 送模块 210。
第二载波确定模块 200, 用于通过下行载波收到数据后,根据承栽数据的 下行载波以及上行载波组和下行载波组的对应关系, 确定承栽上行控制信令 的上行载波。
在具体实施过程中, 第二载波确定模块 200先确定承栽数据的每个下行 载波所在的下行载波组, 然后根据上行载波组和下行载波组的对应关系, 确 定承载数据的下行载波所在的下行载波组对应的上行载波组, 从上行载波组 中选择至少一个上行载波。
具体选择多少个上行载波是根据承载数据的下行栽波所在的下行载波组 对应的上行载波组的数量决定的。
假设有三个承载数据的下行载波分别是下行载波 A、 下行载波 B和下行 载波 C, 其中, 下行载波 A所在的下行载波组对应上行载波组 A1和 A2, 下 行载波 B所在的下行载波组对应上行载波组 A1 ,下行载波 C所在的下行载波 组对应上行载波组 A1和 A3。
则对于下行载波 A, 可以从上行载波组 A1和 A2中选择一个上行载波; 对于下行载波 B, 可以从上行载波组 A1中选择一个上行载波; 对于下行载波 C, 可以从上行载波组 A1和 A3中选择一个上行载波。 较佳地, 由于下行载波 A, B和 C都对应上行载波组 Al, 则可以从上行 载波组 Al中选择一个上行载波。
也就是说, 尽量选择较少的上行载波承载上行控制信令。
如果规定不建立多余出来的每个上行栽波组和下行载波组的对应关系, 默认为如果对应关系中没有上行载波組 A, 则上行载波组 A与所有下行载波 组对应, 则第二载波确定模块 200还可以从多余出来的上行载波组中选择一 个上行栽波。
第二发送模块 210,用于通过第二载波确定模块 200确定的上行载波传输 上行控制信令。
如图 8所示, 本发明实施例数据传输的方法包括下列步骤:
步骤 800、基站根据需要发送数据的容量和生成的下行载波组, 确定承载 数据的下行载波。
其中, 如果需要三个下行载波才能承载需要发送数据, 则从生成的下行 载波组中选择三个下行载波。
选择的三个下行载波可以都在同一个下行载波组中, 也可以不在同一个 下行栽波组中。
较佳地, 基站在一个下行载波组中的下行载波可以承载需要发送数据时, 从该下行载波组中选择至少一个下行载波。
比如: 有三个下行载波就可以承载需要发送的数据, 则查看是否有包含 至少三个下行载波的下行载波组, 如果有, 则可以从一个下行载波組中选择 三个下行载波; 如果没有, 则从多个下行载波组中选择三个下行载波, 在选 择时可以涉及尽量少的下行载波组, 也就是说, 如果可以从两个下行载波组 中选择三个下行载波, 则不选择三个下行载波组。
步骤 801、 基站通过确定的下行载波发送数据。
其中, 步骤 801之后还可以进一步包括:
步骤 802、终端通过下行载波收到数据后,根据承栽数据的下行载波以及 上行载波组和下行载波组的对应关系, 确定承载上行控制信令的上行载波。
在具体实施过程中, 终端先确定承载数据的每个下行载波所在的下行载 波组, 然后根据上行载波组和下行载波组的对应关系, 确定承载数据的下行 载波所在的下行载波组对应的上行载波组, 从上行载波组中选择至少一个上 行载波。
具体选择多少个上行载波是根据承载数据的下行载波所在的下行载波组 对应的上行载波组的数量决定的。
假设有三个承载数据的下行载波分别是下行载波 A、 下行载波 B和下行 载波 C, 其中, 下行载波 A所在的下行载波组对应上行载波组 A1和 A2, 下 行载波 B所在的下行载波组对应上行载波组 A1 ,下行载波 C所在的下行载波 组对应上行载波组 A1和 A3。
则对于下行载波 A, 可以从上行载波组 A1和 A2中选择一个上行载波; 对于下行载波 B, 可以从上行载波组 A1中选择一个上行载波; 对于下行载波 C, 可以从上行载波组 A1和 A3中选择一个上行栽波。 较佳地, 由于下行载波 A, B和 C都对应上行载波组 Al, 则可以从上行 载波组 A1中选择一个上行载波。
也就是说, 尽量选择较少的上行载波承载上行控制信令。
如果规定不建立多余出来的每个上行载波组和下行载波组的对应关系 , 默认为如果对应关系中没有上行载波组 A, 则上行载波组 A与所有下行载波 组对应, 则终端还可以从多余出来的上行载波组中选择一个上行载波。
步骤 803、 终端通过确定的上行载波传输上行控制信令。
从上述实施例中可以看出: 本发明实施例对上行载波进行分组, 生成至 少一个上行载波组, 对多个下行载波进行分组, 生成下行载波组, 所述下行 载波组的数量不大于所述上行载波组的数量; 建立所述上行载波组和所述下 行载波组的对应关系, 其中, 每个下行载波组对应至少一个上行载波组; 根 据所述上行载波组和所述下行载波组的对应关系, 对所述上行载波组中的每 个上行载波配置上行控制信令区域。 由于可以在长期演进多载波系统中配置 上行控制信令区域, 从而提高长期演进多载波系统的性能、 系统资源利用率 和上行传输效率。 发明的精神和范围。 这样, 倘若本发明的这些修改和变型属于本发明权利要 求及其等同技术的范围之内, 则本发明也意图包含这些改动和变型在内。
