Description

时分双工系统中的上行数据传输及接收方法和设备 本申请要求在 2012 年 11 月 19 曰提交中国专利局、 申请号为 201210468139.X, 发明名称为 "时分双工系统中的上行数据传输及接收方法 和设备" 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
本发明涉及无线通信领域, 尤其涉及一种时分双工系统中的上行数据传 输及接收方法和设备。 背景技术
在长期演进 ( Long Term Evolution, LTE ) 系统中, 受限于用户设备 ( User Equipment, UE ) 的最大发射功率, 每个数据包在一个传输时间间隔 ( Transmission Time Interval, TTI ) 内可以利用的功率非常有限, 因此, 恶劣 信道条件下, 上行传输达不到性能要求。 为了提高上行覆盖, LTE 系统引入 了 ΤΤΙ绑定( bundling )方案,期望至少达到高速上行包接入( High Speed Uplink Packet Access, HSUPA ) 的性能。
所谓的 TTI bundling 方案, 即是 UE基于基站的一个调度指示, 在多个 子帧内发送同一数据传输块( Transport Block, TB )在信道编码后的不同冗余 版本(Redundancy Version, RV ), 这样, 可以提高上行数据的传输增益, 从 而增强上行信号的覆盖效果。 该多个上行子帧称为一个绑定子帧束(bundle )。
在 TDD ( Time Division Duplexing, 时分双工) LTE系貌中, 针对三种 上下行配置即上下行配置 0、 1和 6引入了 TTI bundling方案, 并且采用了统 一的 bundling大小( size ),其他上下行配置不支持 TTI bundling技术。 bundling size为一个 bundle中包含的上行子帧的个数, 现有技术中 bundling size为 4。
TDD TTI bundling方案如下:
对于 TDD系统,连续的上行子帧数目小于 bundle大小, 因此数据包的不 同 RV在非连续的上行子帧内发送。 配置 TTI bundling操作的 TDD上下行配 置◦, 1和 6的上行混合自动重传请求 ( Hybrid Automatic Repeat Request, HARQ )进程分别如图 1 -图 3所示。
对于 TDD上下行配置 0,在 non-bundling时,上行 HARQ进程数目为 7; 配置 TTI bundling时, 上行 HARQ进程数目为 3。
对于 TDD上下行配置 1,在 non-bundling时,上行 HARQ进程数目为 4; 配置 TTI bundling时, 上行 HARQ进程数目为 2。
对于 TDD上下行配置 6,在 non-bundling时,上行 HARQ进程数目为 6; 配置 TTI bundling时, 上行 HARQ进程数目为 3。
基于 IP的语音呼叫 (Voice over IP, VoIP )业务模型如图 4所示。
图 4中,从时间上看, VoIP业务数据的传输过程包括语音激活期( talkspurt ) 和静默期( silent period )两种时段。 其中 talkspurt的话音分组周期性到达(周 期为 20ms ), 并且每一个语音分组仅有几十个字节, 可以采用动态调度方式 传输数据包,调度每一个语音分组都需要单独发送物理下行控制信道〔 Physical Downlink Control Channel, PDCCH ), 将引入很大的控制开销。 为了降低控制 开销, 考虑到话音分组的大小基本相同, TD-LTE 中引入了半持续调度 ( Semi-Persistent Scheduling, SPS )。
SPS的具体过程如图 5所示。
在图 5中,基站( eNB )首先发送无线资源控制( Radio Resource Control, RRC )信令, 进行 SPS相应的配置, 如资源分配的周期、 HARQ反馈使用的 资源等。 当必要时(如 Talkspurt到来时), eNB发送 SPS激活 PDCCH, 以为 UE实际分配所使用的 SPS资源, SPS资源一旦激活, 将周期性有效(如图 5 中, SPS资源周期为 τ ), 直到被释放。
在实现本发明的过程中, 发明人发现现有技术中存在以下技术问题: 支持 TTI bundling的三种上下行配置采用统一的 bundling size,并没有针对 每种上下行配置的上行子帧数进行优化, 导致上行子帧利用率达不到 100% , 不能充分利用上行子帧资源以提升覆盖。 发明内容

参见图 6, 本发明实施例提供的 TDD系统中的上行数据传输方法, 包括 以下步骤:
步骤 60: 终端选取绑定的 N个上行子帧; N是在该终端当前采用的 TDD 上下行配置下、 一个业务周期内包含的上行子帧的数目, N为不小于 1 的整 数; 业务周期为周期性到达的业务数据的传输周期; 业务周期可以是由网络 侧通过配置信令(例如高层信令)预先通知给终端的, 也可以是网络侧与终 端预先约定的。
步骤 61 : 终端在 N个上行子帧上传输一个数据传输块( TB )。
具体的,该 N个上行子帧可以为 N个连续的上行子帧或 N个非连续的上 行子帧。 N个连续的上行子帧是指该 N个上行子帧之间不存在其它上行子帧; 非连续的 N个上行子帧是指 N个上行子帧之间存在其它上行子帧。该 N个上 行子帧为 N个非连续的上行子帧时, 能够提高时间分集增益。
在该 N个上行子帧为 N个非连续的上行子帧时,该 N个上行子帧分布在 M个业务周期内, 或者该 N个上行子帧分布在时间段 T内; 其中, M为不小 于 2 的整数; T大于一个业务周期且不是业务周期的整数倍。
在 N个上行子帧为 N个非连续的上行子帧时, N个上行子帧的分布图样 可以如下:
该 N个上行子帧与之前或之后的数据 TB传输所用的 N个上行子帧之间 的分布方式采用子帧级离散分布的方式, 具体可以为以子帧为单位的交织分 布方式或以子帧组为单位的交织分布方式, 子帧组为包含上行子帧的子帧集 合, 该子帧集合中的上行子帧的数目大于 1、且为非整数个无线帧所包含的上 行子帧的个数(比如, 在一个无线帧包含 K个子帧的情况下, 该子帧集合中 的上行子帧的数目大于 1、且不为 K或 K的整数倍)。 在釆用以子帧为单位的 交织分布方式时, 同一数据 TB占用的上行子帧不相邻; 在采用以子帧组为单 位的交织分布方式时, 同一数据 TB 占用的子帧組不相邻。 其中, "之前或之 后的数据 TB" 是指在所述 N个上行子帧上传输一个数据传输块( TB )之前 传输的那个 TB或之后将要传输的 TB块。
该 N个上行子帧与之前或之后的数据 TB传输所用的 N个上行子帧之间 的分布方式,也可以采用无线帧级离散分布的方式, 即同一数据 TB占用的无 线帧不相邻。
N个上行子帧的分布图样可以由网络侧与终端预先约定, 或由网络侧通 过配置信令(例如高层信令)预先通知给终端。
较佳的, 在终端选取绑定的 N个上行子帧之前, 终端可以在第一下行子 帧接收网络侧发送的上行调度(UL grant )信令或半持续调度( SPS )激活命 令; 第一下行子帧与该 N个上行子帧中的第一个子帧之间的时序关系, 遵守 LTE系统协议中规定的上行混合自动重传请求( HARQ )中的调度传输时序关 系, 该调度传输时序关系具体在 3GPP 36.213协议中规定。 可见, 本发明实施 例提供的 TTI bundling方案是可以支持半持续调度的。
步骤 61中, 终端在 N个上行子帧上传输一个数据 TB, 具体实现可以为: 终端按照设定的版本号顺序, 在 N个上行子帧上循环传输一个数据 TB 的多个冗余版本( RV ), 例如 RV0-RV1 -RV2-RV3-RV0. . . .。 网络侧与终端可以 预先约定 RV的使用顺序, 或者由网络侧将 RV的使用顺序通知给终端。
较佳的, 终端在 N个上行子帧上传输一个数据 TB之后, 可以确定网络 侧是否反馈对该数据 TB的接收应答信息, 该应答信息即肯定应答 /否定应答 ( ACK/NACK ); 若是, 则在第二下行子帧接收网络侧反馈的接收应答信息; 其中, 第二下行子帧与 N个上行子帧中的最后一个子帧之间的时序关系, 遵 守 LTE系统协议中规定的上行 HARQ中的传输反馈时序关系 , 该传输反馈时 序关系具体在 3GPP 36.213协议中规定。这里, 网络侧可以预先将网络侧是否 反馈接收应答信息的指示信息通过配置信令(例如高层信令)发送给终端, 或由网络侧与终端预先约定网络侧是否反馈接收应答信息。
较佳的, 在步骤 60中终端选取绑定的 N个上行子帧之前,终端向网络侧 上报该终端支持新的 TTI bundling传输机制 (即本发明实施例提供 TTI bundlin 传输机制,本发明实施例中将该新的 TTI bundlin 传输机制称为第一 TTI bundling传输机制) 的能力信息, 并接收网络侧下发的是否开启该新的 TTI bundling传输机制的通知; 终端在接收网络侧下发的开启该新的 TTI bundling传输机制的通知时, 选取绑定的 N个上行子帧, 并执行后续步骤。 若终端接收到网络侧下发的不开启该新的 TTI bundling传输机制的通知,则按 照现有技术进行上行传输。
这里, 终端可以通过媒体接入控制主配置( M AC-MainConfig )信元 , 接收网络侧下发的是否开启该新的 TTI bundling传输机制的通知。
具体地,网络侧通过在信元 MAC-MainConfig中配置 newttiBundling这一 参数,来通知终端是否开启该新的 TTI bundling传输机制,且网络侧不可以同 时开启传统的 TTI bunding传输机制 (即现有技术提供的 TTI bunding传输机 制)和该新的 TTI bundling传输机制 (即本发明实施例提供的 TTI bunding传 输机制)。 例如:
当 ttiBundling置为 TRUE且 newttiBundling置为 FALSE时, 传统的 TTIbunding开启;
当 ttiBundling置为 FALSE且 newttiBundling置为 TRUE时, 新的 TTIbunding机制开启;
当 ttiBundling置为 FALSE且 newttiBundling置为 FALSE时, 所有的 TTIbunding机制关闭;
由于传统的 TTIbunding传输机制和本申请中新的 TTIbunding传输机制不 会同时开启,所以上例中的参数 ttiBundling与 newttiBundling不可以同时置为 TRUE。

参见图 7, 本发明实施例提供的 TDD系统中的上行数据接收方法, 包括 以下步骤: 步骤 70:网络侧选取绑定的 N个上行子帧; N是在网络侧当前采用的 TDD 上下行配置下、 一个业务周期内包含的上行子帧的数目, N为不小于 1的整 数; 该业务周期为周期性到达的业务数据的传输周期; 业务周期可以是由网 络侧通过配置信令(例如高层信令)预先通知给终端的, 也可以是网络侧与 终端预先约定的。

较佳的 , 在步骤 70中网络侧选取绑定的 N个上行子帧之前,网络侧接收 终端上报的该终端支持新的 TTI bundling传输机制的能力信息,并向该终端下 发是否开启该新的 TTI bundling传输机制的通知;网络侧在向终端下发开启该 新的 TTI bundling传输机制的通知时, 选取绑定的 N个上行子帧, 并执行后 续步骤。
