Description

一种控制信道传输和资源确定方法、 基站及用户设备 本申请要求在 2010年 8月 17日提交中国专利局、申请号为 201010256194.3、 发明名称为"一种控制信道传输和资源确定方法、基站及终端 "的中国专利申请 的优先权, 其全部内容通过引用结合在本申请中。
技术领域
本发明涉及移动通信领域, 尤其涉及一种控制信道传输和资源确定方法、 基站及用户设备。 背景技术
目前, 在长期演进多载波***中, 可能存在多种聚合能力不同的用户设 备, 在使用频傳聚合技术时, 基站根据用户设备的聚合能力和具体的业务需 求, 为用户设备配置非对称载波聚合。 一般情况下, DL ( Down Link, 下行 链路)载波数大于 UL ( Up Link, 上行链路)载波数, 因此, 若要灵活的支 持各种比例的非对称载波聚合, ***需要在每个上行载波内都为各自对应的 下行载波预留一定的反馈资源, 以便用户设备在接收到基站下发的数据包并 确定出 ACK ( ACKnowledge Character, 确认字符) 或 NACK ( Negative ACKnowledg Character, 否定确认字符 )时, 从上行载波预留的反馈资源中选 取一定的资源向基站反馈 ACK或 NACK。
在长期演进多载波***中, 为提高数据传输的可靠性, 一般都是采用 HA Q ( Hybrid Automatic Repeat reQuest , 混合自动重传请求)技术来实现。 当下行 HARQ功能开启后, 用户设备对接收到的下行数据包进行译码, 若译 码正确则通过上行载波预留的资源向基站反馈 ACK; 若译码失败, 则通过上 行载波预留的资源向基站反馈 NACK, 以请求基站重传该下行数据包。 当下 行持续调度业务结束后, 基站向用户设备发送 SPS (半持续调度) 资源释放 指示, 以通知用户设备释放***为其分配的用于此次业务的所有资源; 用户 设备在正确接收到基站下发的 SPS资源释放指示之后, 向基站反馈 ACK。
对于长期演进多载波***, 为支持比 LTE ( Long Term Evolution, 长期演 进) ***更宽的***带宽, 如为支持 100MHz的***带宽, ***可直接分配 100MHz的***带宽, 如图 1所示; 或者, 将已经分配给其他***的全部或部 分频谱聚合起来, 凑成 100MHz的***带宽, 以供给长期演进多载波***, 如图 2 所示; 该种情况下, ***中上下行载波可不对称配置, 如用户设备可 占用 N ( N≥l )个载波进行下行传输, 占用 M ( M > 1 )个载波进行上行传输。
目前, 标准化工作已经基本完成 LTE***(如 Rel-8 ) 中 ACK或 NACK 的反馈方案, 针对每个工作载波, 分别定义下行控制信令、 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; 在 LTE***中传输数据和控 制信令的方式如下:
针对 FDD ( Frequency Division Duplexing, 频分双工) ***, 图 3A、 图 3B分别为 FDD***进行下行传输、 上行传输的结构示意图; 图 3B中, 上行 控制信令占用频带的边缘区, 并通过跳频方式传输, 即在一个上行子帧内的 两个时隙里, 采用不同频段传输上行控制信令; 该种传输方式, 由于无法动 态获知上行子帧中需要承载的控制信道的数量, 因此, 需要在上行子帧中预 留出一定的资源用于上行控制信道传输, 如图 3B中的预留资源(用斜线填充 的区域)。
针对 TDD ( Time Division Duplexing, 时分双工) ***, 图 4为 TDD系 统进行上下行传输的结构示意图, 同理, 在 TDD***中的上行子帧中预留出 一定的资源用于上行控制信道传输, 预留资源为图中用斜线填充的区域。
现有技术中, 对于动态调度的 ACK或 NACK反馈, 用户设备根据接收 到的 PDCCH ( Physical Downlink Control Channel , 物理下行链路控制信道 ) 中的下行控制信令所对应的 CCE ( Control Channel Element, 控制信道元素) 的编号 (用"《 ^表示), 从上行载波中预留的资源中确定出用于反馈 ACK或 NACK的资源的编号(用" 表示), 再利用确定出的编号为 " 的资源向基站 反馈 ACK或 NACK;即每个 PDCCH都对应着一个可用的上行控制信道资源。
目前 ACK或 NACK的传输方式, 需要在每个上行载波中为其对应的下 行载波预留用于反馈 ACK或 NACK的资源。 由于***中, 用户设备的数量 和载波数量都比较庞大, 上行栽波中存在较大的信道资源浪费, 严重的还可 能导致没有可用的上行资源进行数据传输。
综上所述, 目前控制信道资源分配方式, 存在信道资源浪费较大、 信道 资源利用率较低和传输效率较低的问题。 发明内容

本发明实施例基站针对至少一个下行子帧, 在该下行子帧中指示基站在 指定上行控制信道资源集合中为用户设备分配的一个上行控制信道资源 (即 基站在至少一个下行子帧中, 通过 PDCCH为用户设备( UE )在指定上行控 制信道资源集合中分配一个上行控制信道资源;), 指定上行控制信道资源集合 包括至少两类上行信道控制资源, 每类上行控制信道资源对应一种上行控制 信道传输格式; 基站在至少一个下行子帧中传输 PDCCH; 基站在分配的上行 控制信道资源上接收 UE反馈的上行控制信号。 UE在基站下发的至少一个下 行子帧中接收 PDCCH, 该下行子帧中指示基站在指定上行控制信道资源集合 中为 UE分配的一个上行控制信道资源; UE在至少一个下行子帧所指示的 上行控制信道资源中选取用于反馈上行控制信号的上行控制信道资源; 在选 取的上行控制信道资源中反馈上行控制信号 (上行控制信号可包括 ACK和 / 或 NACK )。
采用本发明技术方案, 由于基站已经为用户设备预先指定用于反馈上行 控制信号的上行控制信道资源, 因此, 不需要在每个上行载波中为其对应的 下行载波预留用于反馈上行控制信号的反馈资源, 从而提高了控制信道资源 的利用率和传输效率。
本发明实施例中, 基于信道选择的多比特 ACK或 NACK的复用传输, 用户设备的每个子帧中需要一组控制信道资源; 对于使用 DFT-S-OFDM (基 于离散傅立叶变换扩展的正交频分复用) 的多比特复用传输或使用 PUCCH format la/lb的 ACK或 NACK合并传输, 用户设备在每个子帧中只需要一个 控制信道资源。
需要说明的是, 由于本发明实施例中涉及到 "反馈窗口" 的概念, 虽然 "反馈窗口" 为现有技术, 但是为了进一步使本领域技术人员能够理解, 在 此对于 "反馈窗口" 进行一定程度上的介绍。
目前, 在 LTE- A ( Long Term Evolution- Advanced, 长期演进升级) *** 中最多可支持 5个载波的聚合, 用户设备在反馈上行控制信号时, 在同一个 上行子帧中传输多个下行载波和下行子帧所对应的上行控制信号, 即所谓的 "反馈窗口"。 在 FDD ( Frequency Division Duplex, 频分双工)***, 反馈窗 口的大小为用户设备进行载波聚合时参与聚合的下行载波的数量; 在 TDD ( Time Division Duplex, 时分双工) ***中, 反馈窗口的大小为 ( NxM ), 其中, N为用户设备进行载波聚合时参与聚合的下行载波的数量, M为需要 在同一上行子帧中反馈上行控制信号的下行子帧的数量, M的取值根据上下 行载波数的配置和上行子帧数来确定, 具体可参考表 1。 UL-DL配置

在下面的说明过程中, 先从网络侧和用户设备侧的配合实施进行说明, 最后分别从网络侧与用户设备侧的实施进行说明, 但这并不意味着二者必须 配合实施, 实际上, 当网络侧与用户设备侧分开实施时, 也解决了分別在网 络侧、 用户设备侧所存在的问题, 只是二者结合使用时, 会获得更好的技术 效果。
参见图 5, 为本发明实施例中控制信道传输和资源确定的方法流程图, 该 方法包括步骤:
步骤 501、基站为用户设备分配 N个上行控制信道资源( N≥l ),并将该 N 个上行控制信道资源通知给用户设备。
步骤 502、基站向用户设备发送下行数据包, 并在该下行数据包中的各下 行子帧中,通过 PDCCH为用户设备在指定上行控制信道资源集合中分配一个 上行控制信道资源, 并将分配的上行控制信道资源通知给用户设备。
该步骤中, 指定上行控制信道资源集合中包括至少一类上行控制信道资 源。
比如包括第一类上行控制信道资源和 /或第二类上行控制信道资源。 第一类上行控制信道资源由高层信令配置确定, 该第一类上行控制信道 资源对应的上行控制信道传输格式为 DFT-S-OFDM、 PUCCH format lb with channel selection (使用物理上行控制信道格式 lb的信道选择)或者 PUCCH format la/lb ; 指定上行控制信道资源集合中的第二类上行控制信道资源由 PDCCH的 CCE的序号确定, 该第二类上行控制信道资源对应的上行控制信 道传输格式为 PUCCH format la/lb 或者 PUCCH format lb with channel sdsction。
步骤 503、用户设备根据基站下发的下行数据包,确定出相应的上行控制 信号。
步骤 504、用户设备在基站指定的上行控制信道资源中向基站反馈确定出 的相应的上行控制信号。
上述步骤 501 中, 基站通过高层信令半静态的为用户设备分配 N个用于 反馈上行控制信号 (本发明实施例中, 上行控制信号可包括 ACK 和 /或 NAC )的上行控制信道资源,并根据该 N个上行控制信道资源的标识信息(如 编号) 生成与该用户设备对应的一个指定上行控制信道资源集合, 该指定上 行控制信道资源集合中包括 N个元素, 每个元素对应于一个上行控制信道资 源的编号。 基站通过高层 RRC ( Radio Resource Control, 无线资源控制)信 令将生成的指定上行控制信道资源集合发送给相应的用户设备。
较佳地, 为提高资源利用率, 本发明实施例中分配给用户设备的 N个控 制信道资源还可以被其他用户设备共享; 基站通过调度限制, 多个用户设备 分时复用每个控制信道资源, 从而避免了多个用户设备在同一时间采用同一 控制信道资源而引起控制信道资源碰撞的问题。
上述步骤 502 中, 基站为用户设备分配上行控制信道资源之后, 可通过 在 PDCCH上传输下行调度指示(DL grant )将分配的上行控制信道资源通知 给用户设备, DL grant的指定字节指示分配的上行控制信道资源;
相应的, 用户设备在 PDCCH上接收基站下发的下行调度指示 DL grant。
DL grant的指定字节的比特数设置为: =「log2(N + l), 式 ( 1 );
式(1 )中, L 为指定字节的比特数, W为指定上行控制信道资源集合中 所包含的上行控制信道资源的总数量。
上述步骤 502 中, 基站为用户设备分配上行控制信道资源之后, 基站还 可以在 PDCCH上传输用于指示半持续调度 SPS资源幹放的信令, 所述指示 SPS 资源释放的信令携带有用于指示分配的用于反馈上行控制信号的上行控 制信道资源的指定字节;
相应的, 用户设备在 PDCCH上接收基站下发的用于指示 SPS资源释放 的信令。
较佳地, 上述步骤 504 中, 用户设备为多个上行子帧确定上行控制信道 资源, 确定的上行控制信道资源对应于同一个上行子帧; 若确定的上行控制 信道资源包括至少一个第一类上行控制信道资源, 用户设备使用确定的第一 类上行控制信道资源中最新的上行控制信道资源传输上行控制信息, 其中最 新的上行控制信道资源为多个下行子帧 (该多个下行子帧对应的上行控制信 道资源为第一类上行控制信道资源 ) 中最后一个被用户设备接收的下行子帧 所对应的上行控制信道资源。
较佳地, 基站根据用户设备反馈上行控制信号的方式, 从指定上行控制 信道资源集合中为该用户设备指定用于传输上行控制信号的上行控制信道资 源, 具体为:
用户设备反馈上行控制信号的方式为合并传输, 即用户设备将数据包中 多个调度下行子帧对应的上行控制信号合并成一个上行控制信号: 若用于传 输下行数据包下行子帧的主载波上有唯——个 PDCCH对应的隐式资源,基站 指示用户设备采用该 PDCCH对应的隐式资源来反馈上行控制信号; 否则,基 站从指定上行控制信道资源中选取一个当前能用的上行控制信道资源反馈上 行控制信号。
用户设备反馈上行控制信号的方式为复用传输, 即需要用户设备传输各 调度下行子帧对应的上行控制信号: 若基站在下行子帧中只调度一个 PDCCH 在主载波上传输的数据包,基站指示用户设备使用该 PDCCH对应的隐式资源 传输各调度下行子帧对应的上行控制信号; 否则, 基站从指定上行控制信道 资源集合中选取一个当前能用的上行控制信道资源, 并指示用户设备使用该 指定的上行控制信道资源反馈各调度下行子帧对应的上行控制信号。
较佳地, 为保证基站能够确认下发的数据包的所有下行子帧是否都已经 成功发送给用户设备, 以确保数据传输的可靠性, 本发明实施例中, 当用户 设备接收的所有下行子帧的 DL grant的指定字节对应的上行控制信道资源都 为隐式资源时, 用户设备根据反馈窗口内所收到的最后一个调度下行子帧中 的 DL grant的指定字节对应的上行控制信道资源, 反馈上行控制信号。
为使本领域技术人员更清楚的了解本发明技术方案中, 下面以一具体的 实例来对本发明技术方案进行详细的描述。
假设, 基站通过高层信令给用户设备分配了 3个用于反馈上行控制信号 的上行控制信道资源, 该 3个上行控制信道资源对应的标识信息, 如编号为 资源 1、 资源 2、 资源 3。 基站根据分配的 3个上行控制信道资源的编号为该 用户设备生成指定上行控制信道资源集合为{隐式资源, 资源 1, 资源 2, 资源 3} ; 根 据式( 1 )可知, DL grant的指定字节为 2比特, 得到指定字节和上行控制信 道资源的映射关系如图 6所示。 图 6中, 当 DL grant的指定字节为 "00" 时, 其对应的上行控制信道资源为用户设备的 PDCCH对应的隐式资源,即基站指 示用户设备使用 PDCCH对应的隐式资源来传输相应的上行控制信号; 当 DL grant的指定字节为 "01" 时, 其对应的上行控制信道资源为分配给用户设备 的资源 1 , 即基站指示用户设备使用资源 1传输相应的上行控制信号; 当 DL grant的指定字节为 "10" 时, 其所对应的上行控制信道资源为分配给用户设 备的资源 2, 即基站指示用户设备使用资源 2传输相应的上行控制信号; 当 DL grant的指定字节为 "11 "时, 其所对应的上行控制信道资源为分配给用户 设备的资源 3 , 即基站指示用户设备使用资源 3传输相应的上行控制信号。 在基站端, 当判断用户设备反馈上行控制信号的方式为合并传输时, 针 对数据包中的每个下行子帧, 若用于传输该下行子帧的主载波上有唯一一个
PDCCH对应的隐式资源时, 基站在该下行子帧的 DL grant中携带指定字节 "00" , 否则, 基站在该下行子帧的 DL grant中携带指定字节 "01"、 "10" 或 "11 "。
在基站端, 当判断用户设备反馈上行控制信号的方式为复用传输时, 针 对数据包中的每一个下行子帧, 若基站在该下行子帧上只调度了一个数据包, 且该数据包在主载波上传输时, 基站在该下行子帧的 DL grant中携带指定字 节" 00",否则,基站在该子帧的 DL grant中携带指定字节 "01"、 "10"或 "11"。
结合实际应用, 本发明实施例针对隐式资源的利用, 分别从 FDD***和 TDD***的控制信道资源分配进行进一步详细的描述。
针对 FDD***:
当用户设备接收的多个下行子帧中, 存在某一下行子帧的 DL grant的指 定字节 "00" 时, 不管该用户设备反馈上行控制信号的方式如何, 用户设备 都使用 PUCCH format la/lb在 PDCCH对应的隐式资源上传输相应的上行控 制信号, 如: 当用户设备反馈上行控制信号的方式为合并传输, 用户设备采 用与隐式资源对应的上行控制信道传输格式 (如 PUCCH format lb with channel selection或者 PUCCH format la/lb ), 在 PDCCH对应的隐式资源上传 输合并后的上行控制信号; 当用户设备反馈上行控制信号的方式为复用传输, 用户设备釆用与该隐式资源对应的上行控制信道传输格式(如 DFT-S-OFDM ) 则在 PDDCH对应的隐式资源中传输各调度下行子帧对应的上行控制信号。
针对 TDD***:
用户设备反馈上行控制信号的方式为合并传输, 当用户设备接收的某一 下行子帧的主载波上有唯——个 PDCCH对应的隐式资源时,用户设备采用与 该隐式资源对应的上行控制信道传输格式(如 PUCCH format lb with channel selection, PUCCH format la/lb )在该 PDCCH对应的隐式资源中反馈上行控 制信号; 较佳地, 为保证基站能够确认下发的数据包的所有子帧是否都已经成功 发送给用户设备, 以确保数据传输的可靠性, 本发明实施例中, 当用户设备 接收的所有下行子帧的 DL grant的指定字节对应的上行控制信道资源为隐式 资源时, 用户设备还可选取数据包中最后一个调度下行子帧的 DL grant中的 指定字节对应的上行控制信道资源, 传输合并后的上行控制信号;
用户设备反馈上行控制信号的方式为复用传输, 用户设备采用与隐式资 源对应的上行控制信道传输格式, 在最后一个调度下行子帧的 DL grant的指 定字节对应的上行控制信道资源中, 反馈各下行子帧对应的上行控制信号, 具体如下:
若基站在反馈给用户设备的某一下行子帧的 DL grant 的指定字节为非 "00" 时, 则基站在反馈给用户设备的后续下行子帧的 DL grant的指定字节 也为上述非 "00" 的指定字节。
用户设备反馈上行控制信号的方式为信道选择复用传输, 若用户设备接 收到的所有下行子帧的 DL grant 中的指定字节为 "00" 时, 用户设备使用 PUCCH format la/lb在 PDCCH对应的隐式资源上进行上行控制信道资源的 选择, 并在选择的上行控制信道资源中传输各下行子帧对应的上行控制信号; 若用户设备接收到的后续部分的多个下行子帧的 DL grant中的指定字节相同 且都为非 "00" 时, 则用户设备采用与费隐式资源对应的上行控制信道传输 格式(如 PUCCH format la/lb, PUCCH format lb with channel selection ) , 在 该指定字节对应的非隐式资源中传输各下行子帧对应的上行控制信号。
用户设备反馈上行控制信号的方式为 DFT-S-OFDM复用传输, 当用户设 备接收的所有下行子帧的 DL grant中的指定字节为 "00" 时, 用户设备使用 PUCCH format la/lb在 PDCCH对应的隐式资源中传输各下行子帧对应的上 行控制信号; 若用户设备接收的后续部分下行子帧的 DL grant中的指定字节 相同且都为非 "00" 时, 则用户设备使用 DFT-S-OFDM在指定字节对应的非 隐式资源中传输各下行子帧对应的上行控制信号。 下面以具体的实例来对上述 TDD***的上行控制信号的反馈进行更为清 楚、 详细的描述。
参见图 7, 为本发明实施例中针对 TDD***中为配置为上行控制信号合 并传输的用户设备分配反馈资源的示意图, 图 7中:
假设用户设备接收到的数据包包含四个下行子帧, 分别用下行子帧 1、 下 行子帧 2、 下行子帧 3和下行子帧 4表示, 基站在下行子帧 1、 下行子帧 2和 下行子帧 4只调用了一个数据包,且下行子帧 1、 下行子帧 2和下行子帧 4分 别都在主载波上传输, 因此, 该三个子帧所对应的 DL grant中的指定字节为 "00" (即隐式资源), 而下行子帧 3 的数据在副载波上传输, 该下行子帧 3 所对应的 DL grant中的指定字节为 "01" ; 用户设备将该四个下行子帧对应的 上行控制信号进行合并之后的上行控制信号在 PDCCH对应的隐式资源上反 馈给基站。
参见图 8, 为本发明实施例中针对 TDD***中为配置为上行控制信号复 用传输的用户设备分配反馈资源的示意图, 图 8中:
假设用户设备接收到的数据包包含四个下行子帧, 分别用下行子帧 1、 下 行子帧 2、 下行子帧 3和下行子帧 4表示, 基站在下行子帧 1、 下行子帧 2上 只调用了一个数据包, 且下行子帧 1、 下行子帧 2分别都在主载波上传输, 因 此, 该下行子帧 1、 下行子帧 2对应的 DL grant中的指定字节为 "00" (即 隐式资源) ; 而基站在下行子帧 3上调用了多个数据包, 因此下行子帧 3所 对应的 DL grant中的指定字节为 "01 " (即为非隐式资源) ; 基站在下行子 帧 4 中只调用一个数据包, 且下行子帧 4在主载波上传输, 虽然下行子帧 4 满足使用隐式资源的奈件, 但是, 由于其前面下行子帧 3的 DL grant中的指 定字节为 "01" , 因此, 下行子帧 4的 DL grant中的指定字节也为 "01" 。 用户设备在 "01 " 对应的上行控制信道资源中传输各调度下行子帧对应的上 行控制信号。
本发明实施例中, DL grant中的指定字节并不仅限于用 "00" 、 "01 " 、 "10" 、 "11 " 等比特来表示分配给用户设备的多个上行控制信道资源, 还 可以通过其他的方式实现, 如在 DL grant中携带上行控制信道资源的编号、 名称等, 实现方式多种多样, 本领域技术人员应该可以理解。

较佳地, 第二收发单元 91在资源确定单元 92选取的上行控制信道资源 中反馈上行控制信号, 具体应用为:

本发明实施例中, 基站通过高层信令半静态的为用户设备分配多个用于 反馈上行控制信号的控制信道资源, 并将分配的多个控制信道资源通知给用 户设备; 在数据传输时, 基站针对发送给用户设备的数据包中的每一调度下 行子帧, 从分配给该用户设备的多个控制信道资源中为该下行子帧指定用于 反馈上行控制信号的控制信道资源; 用户设备在接收到基站下发的数据包, 确定出相应的上行控制信号; 用户设备从基站指定的控制信道资源中选取相 应的控制信道资源向基站反馈上行控制信号。 采用本发明技术方案, 用户设 备在对接收到的数据包进行译码之后确定出需要反馈的上行控制信号, 并采 用基站指定的控制信道资源反馈上行控制信号即可, 不需要在每个上行载波 中为其对应的下行载波预留用于反馈上行控制信号的控制信道资源, 因此, 本发明技术方案充分利用了上行控制信道资源、 提高了***传输效率。
显然, 本领域的技术人员可以对本发明进行各种改动和变型而不脱离本 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。
