Description
TTI集束的传输处理方法及装置、 网络侧设备、 UE 技术领域 本发明涉及移动通信领域, 具体而言, 涉及一种传输时间间隔集束(Transmission Time Interval bundling, 简称 TTI bundling) 的传输处理方法及装置、 网络侧设备、 用 户设备 (User Equipment, 简称 UE)。 背景技术 长期演进 (Long-Term Evolution, 简称 LTE) 系统的无线接入网络包括: 网络侧 (增强的节点 B, 演进型基站(evolved Node B, 简称 e B))与 UE, 其中, 网络侧与 核心网络或其它网络相连, 并通过无线接口与位于该网络侧所服务的小区中的 UE进 行通信。为了提升上行链路(Uplink,简称 UL)网络电话(Voice over Internet Protocol, 简称 VoIP)业务的覆盖, LTE在物理层引入了 TTI bundling技术。 其中, TTI bundling 是指调度器为 UE分配超过 1个传输时间间隔 ΤΉ的无线资源。 基本思想是允许 UE 使用连续的 ΤΉ连续发送同一传输块的不同冗余版本(Redundancy Version,简称 RV), 并且将上述操作作为该传输块的 1次传输尝试。 注: 由于 ΤΉ和子帧通常是等价的, 所以本文后续内容不再对两者进行区分。 已知在使能 TTI bundling传输的情况下, 总的 UL 混合自动重传请求 (Hybrid Automatic Repeat Request, 简称 HARQ)进程数为 4个; 另外对于 VoIP业务, 其传输 块的到达间隔或周期通常为 20ms或 20个子帧, 并且其空中接口延时限制通常被设置 为大约 50ms。 具体地, 如图 1所示, 调度器通过在无线帧 n-1子帧 6上的 1次半持续 ( Semi-Persistent Scheduling, 简称 SPS) 类型的上行授予, 为 UE分配以传输块到达 间隔 20ms为周期的上行子帧资源 (即无线帧 n+k (k=0,2,4,6, ... ... ) 的子帧 0至 3 ), 这些周期性的上行子帧资源分别被用于每个 VoIP 传输块的首次传输尝试。 传输块 0 利用 HARQ进程 0资源, 第 1次传输尝试在无线帧 n子帧 0至 3的范围内执行, 如果 相应下行 HARQ应答为否定的非确认字符 (Non-Acknowledgement, 简称 NACK) 应 答, 第 2次传输尝试在无线帧 n+1子帧 6至 9的范围内执行, 以此类推, 直到相应应 答为肯定的确认字符 (Acknowledgement, 简称 ACK) 应答, 或达到了最大 4次的传 输尝试次数, 传输块 0终止传输。 类似地, 其它传输块也是利用指定 HARQ进程资源 通过上述方式实现 TTI bundling传输。
在现有的 LTE (A) 系统上行授予下行控制信息 (Downlink Control Information, 简称 DCI) 格式中, 调制编码方案 (Modulation and coding scheme, 简称 MCS ) 字段 包括 5个比特 (bit), 如下表 1所示, 索引 IMCS范围为 0至 31 (十进制)。 其中, 索引 0至 28被用于指示 HARQ首次传输下的调制阶数和传输块大小(Transport Block Size, 简称为 TBS )索引 (RV索引固定为 0), 索引 29至 31被用于指示 HARQ某次重传下 的 RV索引 (调制阶数和 TBS索引与首传相同)。然而, 在使能 ΤΉ bundling传输的情 况下, 上述 32个(0至 31 ) 索引中的大部分不会被使用。 例如, 由于 TTI bundling传 输主要被用于 VoIP业务 (有效载荷较小), 此时大小为 2的调制阶数 (正交相移键控 ( Quadrature Phase Shift Keying, 简称 QPSK) ) 和较小的 TBS索引已经是足够的, 从 而索引 11至 28可能不会被使用; 另外, 由于 ΤΉ bundling的大小为 4个子帧, 每一 次 bundling传输 (包括首传和重传) 取值范围为 0至 3的 RV索引都会被遍历, 从而 专门用于 HARQ重传 RV索引指示的索引 29至 31也可能从不会被使用。 表 1

HARQ进程资源的借用过程。
S204: 向 UE发送上述触发消息。 通过上述步骤的执行, 当获取到用于触发采用增强的传输时间间隔集束传输机制 (增强的混合自动重传请求 HARQ操作或者 HARQ进程资源的借用过程) 的上行授 予 DCI格式中的 MCS字段时, 随即向用户发送上述触发信息。采用这样的技术方案, 能够有效的解决现有技术中由于受限于 UL链路或 UE的最大发射功率, 上行 VoIP业
务仍然是覆盖的瓶颈,无法满足期望的覆盖需求的问题。有效地增强了上行 VoIP业务 覆盖性能, 并且还避免了对高层协议或者规范的较大影响。 在本实施例中, 上述增强的 HARQ操作包括: 设置 HARQ RTT为 12ms。 本发明实施例对上述技术方案的进一步改进在于,上述 HARQ进程资源的借用过 程包括以下之一: 持续 HARQ进程资源的借用过程、 半持续 HARQ进程资源的借用 过程和动态 HARQ进程资源的借用过程。 其中, 持续 HARQ进程资源的借用过程可 以表现为以下实现形式: 对于所有连续的 VoIP传输块, 位于首次传输尝试 HARQ进 程资源之后的第 1个 HARQ进程资源被上述 VoIP传输块借用;半持续 HARQ进程资 源的借用过程可以表现为以下实现形式: 对于至少 1个连续的 VoIP传输块,位于首次 传输尝试 HARQ进程资源之后的第 1个上述 HARQ进程资源被 VoIP传输块借用; 动 态 HARQ进程资源的借用过程可以表现为以下实现形式: 对于 1个 VoIP传输块, 位 于首次传输尝试 HARQ进程资源或重传尝试 HARQ进程资源之后的第 X个 HARQ进 程资源被上述 VoIP传输块借用, 其中, 上述 X是从以下之一取值: 1、 2、 3。 需要说明的是, 上述重传尝试是指实际操作过程中除首次传输尝试以外的所有其 它传输尝试中的 1次传输尝试。 在以下两种情形下, 表示上述增强的传输时间间隔集束传输机制被触发:
( 1 )在采用上述增强的 HARQ操作、 上述持续 HARQ进程资源的借用过程以及 上述动态 HARQ进程资源的借用过程的情况下, 且在上述 MCS字段表示的十进制索 引为以下之一时: 29、 30、 31; ( 2 )在采用上述半持续 HARQ进程资源的借用过程的情况下, 且在上述 MCS字 段表示的十进制索引为以下取值时: 索引值大于 10的取值。 本实施例对上述技术方案的进一步改进在于, 当利用上述 MCS 字段触发半持续 HARQ进程资源的借用过程时, 上述 MCS字段还用于确定半持续 HARQ进程资源借 用过程持续的连续传输块数, 除了本实施提供的确定上述连续传输块数的方式外, 对 于上述半持续 HARQ进程资源借用过程,其持续的连续传输块数也可以通过预先设定 的方式确定上述连续传输快的数目。 本实施例中的上述 MCS字段的作用并不局限于上述功能。 上述 MCS字段还用于 当利用所述 MCS字段触发所述持续 HARQ进程资源的借用过程时,所述 MCS字段还
用于关闭所述持续 HARQ进程资源的借用过程。 例如, 当上述 MCS字段表示的十进 制索引不等于 31时, 表示所述持续 HARQ进程资源的借用过程被关闭。 本实施例对上述技术方案的进一步改进在于, 对于上述增强的 HARQ操作、 上述 持续 HARQ进程资源的借用过程以及上述半持续 HARQ进程资源的借用过程, 上述 MCS字段在传输块 0到达时刻之前的第 4个子帧上传输, 其中, 上述传输块 0是使能 增强的传输时间间隔集束传输机制的第 1个传输块; 对于上述动态 HARQ进程资源的借用过程, 上述 MCS字段在指定传输块首次传 输尝试或重传尝试 HARQ进程资源的第 1个子帧上传输, 其中, 上述指定传输块是使 能增强的传输时间间隔集束传输机制的传输块。 为了更好地理解上述实施例, 以下结合优选实施例详细说明。 需要说明的是, 以 下优选实施例的方案并不构成对本发明的限定。 具体地: 图 3是根据本发明实施例的利用上行授予 DCI格式中 MCS字段触发增强的 HARQ 操作的示意图。 注: 附图中图案參表示正常的上行授予, 图案▲表示用于触发增强的 HARQ操作的上行授予。 如图 3所示: 在使能 ΤΉ bundling传输的情况下, 利用上行授予 DCI格式中的 MCS字段触发 增强的 HARQ操作。例如如果上述 MCS字段表示的十进制索引 IMCS等于 31, 表示增 强的 HARQ操作被触发或使能。 其中, 上述 RTT是指从一次传输尝试开始至下一次 传输尝试开始的持续时间间隔。 具体地, 用于触发增强的 HARQ操作的上行授予在无线帧 n-1子帧 6被发射, 其 中, 无线帧 n-1子帧 6是位于传输块 0到达时刻之前的第 4个子帧, 传输块 0是使能 增强的 HARQ操作的第 1个传输块。在增强的 HARQ操作的情况下, 在大约 50ms的 延时限制下, 传输块 0至多能够执行 5次传输尝试, 占据 20个子帧资源。 类似地, 其 它传输块 1 (>0 ) 同样至多能够执行 5次传输尝试。 图 4是根据本发明优选实施例的触发持续 HARQ进程资源的借用过程的示意图。 如图 4所示,注: 附图中图案參表示正常的上行授予, 图案▲表示用于触发持续 HARQ 进程资源借用过程的上行授予。 在使能 TTI bundling传输情况下, 利用上行授予 DCI格式中 MCS字段触发持续 HARQ进程资源的借用过程。 其中, 上述持续 HARQ进程资源的借用过程是指: 对于 所有的连续的 VoIP传输块, 位于首次传输尝试 HARQ进程资源之后的第 1个 HARQ
进程资源被传输块借用。 例如如果上述 MCS字段表示的十进制索引 IMCS等于 31, 表 示上述持续的 HARQ进程资源的借用过程被触发。 具体地, 如图 4所示, 用于触发持续 HARQ进程资源借用过程的上行授予在无线 帧 n-1子帧 6被发射, 其中, 无线帧 n-1子帧 6是传输块 0到达时刻之前的第 4个子 帧, 传输块 0是使能持续 HARQ进程资源借用的第 1个传输块。 在正常情况下, 传输 块 0不会使用 HARQ进程 1资源, 但在使能持续 HARQ进程资源借用过程的情况下, 传输块 0除了使用 HARQ进程 0资源以外,还会使用位于传输块 0首次传输尝试 HARQ 进程 0资源之后的 HARQ进程 1资源, 即 HARQ进程 1资源被传输块 0借用。 类似 地, HARQ进程 2资源被传输块 1借用, HARQ进程 3资源被传输块 2借用, HARQ 进程 0资源被传输块 3借用, 以此类推。 另外,在持续 HARQ进程资源借用的情况下, 同样可以利用上行授予 DCI格式中 MCS字段关闭上述持续 HARQ进程资源的借用过程。例如如果上述 MCS字段表示的 索引 IMCS不等于 31, 表示上述持续 HARQ进程资源的借用过程被关闭。 图 5是根据 本发明优选实施例的触发半持续 HARQ进程资源的借用过程,并确定上述过程持续的 传输块数的示意图。 如图 5所示, 注: 附图中图案《表示正常的上行授予, 图案 表 示用于触发半持续 HARQ进程资源借用过程的上行授予。 在使能 ΤΉ bundling传输的情况下, 利用上行授予 DCI格式中的 MCS字段触发 半持续 HARQ进程资源的借用过程, 并确定上述过程持续的连续传输块数。 其中, 上 述持续的连续传输块还可以采用预先设定的方式。上述半持续 HARQ进程资源借用过 程是指:对于至少 1个连续 VoIP传输块,位于首次传输尝试 HARQ进程资源后的第 1 个 HARQ进程资源被传输块借用。 例如如果上述 MCS字段表示的十进制索引 IMCS大 于 10,表示半持续 HARQ进程资源的借用过程被触发,并且上述持续的传输块数由具 体的十进制索引 IMCS的取值指示(如下表 2所示)。 以上述 MCS字段表示的索引 IMCS 等于 13为例, 表示半持续 HARQ进程资源借用过程被触发, 且持续的连续传输块数 为 3个。 表 2

具体地, 如图 5所示, 用于使能半持续 HARQ进程资源借用的上行授予在无线帧 n-1子帧 6被发射, 其中, 无线帧 n-1子帧 6是传输块 0到达时刻之前的第 4个子帧, 传输块 0是使能半持续 HARQ进程资源借用的连续 3个传输块中的第 1个。在正常情 况下, 传输块 0不会使用 HARQ进程 1资源, 但在使能半持续 HARQ进程资源借用 过程的情况下,传输块 0除了使用 HARQ进程 0资源以外还会使用位于传输块 0首次 传输尝试 HARQ进程 0资源之后的 HARQ进程 1资源, 即 HARQ进程 1资源被传输 块 0借用。 类似地, HARQ进程 2资源被传输块 1借用, HARQ进程 3资源被传输块
2借用。由于上述半持续 HARQ进程资源借用过程持续的连续传输块数被设定为 3个, HARQ进程 0资源不再被传输块 3借用。 当触发的是动态 HARQ进程资源的借用过程时, 存在以下两种情况: 在使能 ΤΉ bundling传输的情况下, 利用上行授予 DCI格式中的 MCS字段触发 动态的 HARQ进程资源的借用过程。 其中, 上述动态 HARQ进程资源借用过程是指: 对于 1个 VoIP传输块, 位于首次传输尝试 HARQ进程资源或重传尝试 HARQ进程资 源之后的第 X ( =1,2,或 3 )个 HARQ进程资源被该传输块借用。 例如, 如果上述 MCS 字段表示的十进制索引 IMCS大于 28, 表示动态的 HARQ进程资源借用过程被触发, 并且上述变量 X的取值由具体的索引 IMCS的取值指示 (如下表 3所示)。 以索引 IMCS 取值等于 29为例, 表示动态的 HARQ进程资源借用过程被使能并且 X的取值为 1。 表 3

图 8是根据本发明实施例的传输时间间隔集束的传输处理方法的另一流程图。 如 图 8所示, 该方法相对于图 2所示实施例, 从 UE侧进行说明, 具体包括步骤 S802至 步骤 S804:
S802: UE接收来自网络侧设备的用于触发采用增强的传输时间间隔集束传输机 制的触发信息; 在该步骤中, 上述触发信息包括: 上行授予 DCI格式中的 MCS字段; 上行授予 DCI格式中的 MCS字段与资源分配 RA字段的结合。 例如, 当上述所述 MCS字段表 示的十进制索引等于最小值 0, 并且 RA字段表示的十进制索引等于最大值时, 上述 增强传输时间间隔集束传输机制被触发; 上述增强的传输时间间隔集束传输机制包括 以下至少之一: 增强的混合自动重传请求 HARQ操作、 HARQ进程资源的借用过程。
S804: 在上述触发信息的触发下, 上述 UE采用上述增强的传输时间间隔集束传 输机制进行上行传输。 通过上述步骤的执行, 当 UE接收到用于触发采用增强的传输时间间隔集束传输 机制 (增强的 HARQ操作或者 HARQ进程资源的借用过程) 的上行授予 DCI格式中 的 MCS字段时, UE采用上述增强的传输时间间隔集束传输机制进行上行传输。 采用 这样的技术方案, 能够有效的解决现有技术中由于受限于 UL链路或 UE的最大发射 功率, 上行 VoIP业务仍然是覆盖的瓶颈, 无法满足期望的覆盖需求的问题。有效地增 强了上行 VoIP业务覆盖性能, 并且还避免了对高层协议或者规范的较大影响。 在本实施例中, 上述增强的 HARQ操作包括: 设置 HARQ RTT为 12ms。 本发明对上述技术方案的进一步改进在于,上述 HARQ进程资源的借用过程包括 以下之一: 持续 HARQ进程资源的借用过程、 半持续 HARQ进程资源的借用过程和 动态 HARQ进程资源的借用过程。 在本实施例中还提供了一种传输时间间隔集束的传输处理方法装置, 该装置应用 于网络侧设备, 用于实现上述实施例及优选实施方式, 已经进行过说明的不再赘述, 下面对该装置中涉及到的模块进行说明。 如以下所使用的, 术语"模块"可以实现预定 功能的软件和 /或硬件的组合。 尽管以下实施例所描述的装置较佳地以软件来实现, 但 是硬件, 或者软件和硬件的组合的实现也是可能并被构想的。 图 9是根据本发明实施 例的传输时间间隔集束的传输处理装置的结构框图。 如图 9所示, 该装置包括:
