Description

终端实现绝对 /相对授权的方法及终端 技术领域
本发明涉及高速上行分组接入（HSUPA, High Speed Uplink Packet Access ) 系统中的调度技术， 尤指一种终端实现绝对 /相对授权的方法及终 端。 背景技术
HSUPA是针对上行链路性能增强的技术。 HSUPA通过有效地利用功 率， 在信道条件好时， 提高终端向接入网的上行方向的数据传输速率。 HSUPA技术沿用了传统无线通信技术的大部分特性， 比如小区选择、同步、 随机接入、 基本移动性管理等。 HSUPA的关键技术包括： 混合的自动重发 请求（HARQ , Hybrid Automatic Repeat Request ), 节点 B的快速调度、 2 毫秒的短传输时间间隔 （TTI, Transmission Time Interval )等。
在 HSUPA调度算法中， 通过考虑接收总带宽功率（RTWP, Received Total Wide band Power ), 终端发射功率， 终端功率余量、 终端緩存容量、 业务以及优先级别等信息来决定终端的上行方向数据传输速率。 并通过绝 对授权或相对授权的下行调度控制信令来通知终端当前最大可用的上行功 率资源， 上行功率资源限定了终端的上行方向最大数据传输速率。
其中，绝对授权提供了终端可用的上行最大功率资源，为每一次 HARQ 进程最大允许使用的增强型专用信道专用物理数据信道 ( E-DPDCH， Enhanced Dedicated Physical Data Channel ) /专用物理控制信道 ( DPCCH, Dedicated Physical Control Channel )功率比； 相对授权表示终端在前一次调 度使用的功率资源基础上上调或者减少一个相对值， 服务的相对授权具体 包括上调 （UP )、 维持不变 （HOLD )、 减少 （DOWN )这 3种值， 非服务 的相对授权具体包括 HOLD、 DOWN这 2种值。 终端接收到调度后， 会计 算出一个服务授权。 服务授权用于增强传输格式合并 （E-TFC , Enhanced Transport Format Combination )选择算法时，表示在激活的 HARQ进程中传 输数据的最大 E-DPDCH/DPCCH功率比。
如果终端接收到绝对授权， 则参照表 1 (绝对授权值映射关系表一）或 者表 2 (绝对授权值映射关系表二）来更新服务授权。
Figure imgf000004_0001
表 1
比如， 终端接收到绝对授权为索引号 31 , 使用表 1所示的绝对授权值 映射关系表一来更新服务授权， 如表 1所示， 索引号 31 代表绝对授权值为 (168/15)2x6, 所以， 终端更新服务授权为（168/15)2x6, 也就是说， 终端在激 活的 HARQ 进程中传输数据的最大 E-DPDCH/DPCCH 功率比为 (168/15)2x6。
Figure imgf000005_0001
比如， 终端接收到绝对授权为索引号 31 , 使用表 2所示的绝对授权值 映射关系表二来更新服务授权， 如表 2所示， 索引号 31 代表绝对授权值为 (377/15)2χ4, 因此， 终端更新服务授权为 (377/15)2χ4, 也就是说， 终端在激 活的 HARQ 进程中传输数据的最大 E-DPDCH/DPCCH 功率比为 (377/15)2x4。
如果终端接收到相对授权， 则根据相对授权转换为服务授权的算法来 更新服务授权。 相对授权转换为服务授权的算法具体为：
终端参照表 3 (调度授权表一）或者表 4 (调度授权表二），
Figure imgf000006_0001
Figure imgf000007_0001
表 4
当终端接收到一个服务的相对授权（在冲突解决后的小区专用信道状 态或者小区前向接入信道状态）， 终端确定表 3或者表 4内大于等于参考功 率比的最小功率比， 确定该最小功率比在表中的索引号， 将该确定的索引 号记为调度授权（功率比）。 其中， 参考功率比为： 与这次数据传输具有相 同 HARQ进程的前一个 TTI所用于 E-TFC选择的 E-DPDCH/DPCCH功率 比。 此时，
当该服务的相对授权为 UP时， 如果调度授权（功率比）小于 3步长索 引门限， 则终端更新服务授权为 MIN (调度授权（功率比） +3 , 37)索引号对 应的表 3或表 4中的调度授权， MIN为取最小值运算符；如果调度授权（功 率比） 小于 2步长索引门限， 且大于等于 3步长索引门限， 则终端更新服 务授权为 MIN (调度授权（功率比 ) +2 , 37)索引对应的表 3或表 4中的调度 授权； 如果调度授权（功率比） 大于等于 2 步长索引门限， 则终端更新服 务授权为 MIN (调度授权（功率比 ) +1 , 37)索引号对应的表 3或表 4中的调 度授权；
当该服务的相对授权为 DOWN时，终端更新服务授权为 MAX (调度授 权（功率比） -1 , 0)索引号对应的表 3或表 4中的调度授权。
当终端接收到一个非服务的相对授权， 终端确定表 3或者表 4内大于 等于最大值的参考记录保存功率比的最小功率比，确定该最小功率比在表 3 或表 4中的索引号， 将该索引号记为调度授权（记录保存功率比）。 其中， 参考记录保存功率比为：与这次数据传输具有相同 HARQ进程的前一个 ΤΉ 所用于 E-TFC选择的 E-DPDCH/DPCCH功率比更新为新值时所记录保存的 这个新值。 此时，
当该非服务的相对授权为 DOWN时，终端更新服务授权为 MAX (调度 授权（记录保存功率比） - 1 , 0)索引号对应的表 3或表 4中的调度授权。
HSUPA使用的调制方式有正交相移键控（ QPSK, Quadrature Phase Shift Keying )和 16个样点的幅度相位联合调制（ 16QAM, 16 Quadrature Amplitude Modulation ) 两种。 其中， QPSK是一种数字调制方式， 分为绝对相移和相 对相移两种； 16QAM是一种数字高阶调制方式，每个符号的信息量是 QPSK 的 2倍。 相对于 QPSK的普通调制方式， 16QAM能够更有效的利用信道带 宽。
在工程实际运用中， 当终端进行 16QAM操作时，釆用现有技术实现授 权时会出现如下问题：
问题一： 当终端进行 16QAM操作时， 终端接收到绝对授权为索引号 31(以参照表 1为例 )，如表 1所示，索引号 31 代表绝对授权值为（168/15)2x6, 因此， 终端更新服务授权为（168/15)2x6, 也就是说， 在激活的 HARQ进程 中传输数据的最大 E-DPDCH/DPCCH功率比为（168/15)2x6。 随后， 如果终 据传输速率， 比如， 此时终端功率余量较高或终端緩存容量较高， 那么， 限定只能够通过服务的相对授权为 UP, 参照表 4, 根据相对授权转换为服 务授权的算法来更新服务授权， 从而一步一步的向上调整服务授权， 每调 整一个步长， 至少需要一个 TTI 的时间长度。 如果期望服务授权从 (168/15)2x6 调整到 (377/15)2x4, 则至少需要调整两个步长， 至少需要两个 TTI的时间长度。 HSUPA调度是需要在一个 TTI的时间长度处理完毕， 如 果需要两个 TTI的处理时间长度， 将增加了一倍的处理时延， 对于性能影 响较大， 无法保证通过快速调度来及时响应终端。
问题二： 当终端进行 16QAM操作时， 终端接收到绝对授权为索引号 2 (以参照表 2为例）， 如表 2所示， 索引号 2代表绝对授权值为（15/15)2, 所 以终端更新服务授权为（15/15)2, 也就是说， 在激活的 HARQ进程中传输数 据的最大 E-DPDCH/DPCCH功率比为（15/15)2。 随后， 如果终端期望能够获 得更小的 E-DPDCH/DPCCH功率比来降低上行方向数据传输速率， 比如， 此时终端功率余量不够或终端緩存容量接近清空， 则限定只能够通过相对 授权为 DOWN, 参照使用表 4 (调度授权表二）， 根据相对授权转换为服务 授权的算法来更新服务授权， 从而一步一步向下调整服务授权。 每调整一 个步长， 至少需要一个 TTI的时间长度， 比如期望服务授权从 (15/15)2调整 到 (7/15)2,则至少需要调整两个步长，至少需要两个 TTI的时间长度。 HSUPA 调度是需要在一个 TTI的时间长度处理完毕， 如果需要两个 TTI的处理时 间长度， 必然增加了一倍的处理时延， 对于性能影响较大， 无法保证通过 快速调度来实现对终端的及时响应。
问题三： 当终端进行 16Q AM操作时，终端接收到的绝对授权为索引号 3 (以参照表 1为例 ), 如表 1所示， 索引号 3代表绝对授权值为（11/15)2, 所以终端更新服务授权为（11/15)2, 也就是说， 在激活的 HARQ进程中传输 数据的最大 E-DPDCH/DPCCH功率比为（11/15)2。 随后， 比如终端功率余量 不够或终端緩存容量接近清空， 那么终端会期望能够获得更小的 E-DPDCH/DPCCH 功率比， 比如 (7/15)2, 以降低上行方向数据传输速率。 由于此时服务授权已经为（11/15)2, 即已经是表 4的最下限， 无法再使用相 对授权为 DOWN来一步一步的向下调整服务授权，造成了相对授权的调度 调整方式的失效。
从上述当终端进行 16QAM操作时，釆用现有技术实现授权时出现的问 题来看， 其原因在于表 1、 表 2、 表 3和表 4的边界不对齐， 而且各表中的 上限和下限均不同， 特别是在偏大值（即接近上限）和偏小值（接近下限） 的使用时， 导致终端对授权的调整的处理时延， 甚至是失败， 从上述分析 可见， 现有终端授权方法无法保证通过快速调度来及时响应终端， 甚至造 成相对授权的调度调整方式的失效，降低了 HSUPA技术在工程应用中的性 能。 发明内容

图 1为本发明实现绝对 /相对授权的方法的流程图， 如图 1所示， 包括： 步骤 100: 终端判断是否进行 16Q AM操作， 如果进行 16QAM操作， 则进入步骤 102; 如果不进行 16QAM操作， 则进入步骤 101。
终端是否进行 16QAM操作，由无线网络控制通过无线资源控制（ RRC ) 层控制信令来指示给终端。 具体地， 无线网络控制器发送 RRC层控制信令 给终端，信令中携带终端是否进行 16QAM操作的指示信息。如果指示信息 标识终端进行 16Q AM操作， 则终端进行 16QAM操作； 如果指示信息标识 终端不进行 16Q AM操作 , 则终端不进行 16Q AM操作。
步骤 101 : 当终端不进行 16QAM操作时， 终端使用绝对授权值映射关 系表一映射绝对授权， 并且， 终端使用调度授权表一更新服务授权。
本步骤中， 终端使用绝对授权值映射关系表一映射绝对授权为： 终端 接收到绝对授权的索引号后， 使用绝对授权值映射关系表一获取该索引号 映射的绝对授权值。
终端使用调度授权表一更新服务授权为： 终端参照调度授权表一， 根 据相对授权转换为服务授权的算法来更新服务授权。在该算法中， 3步长索 引门限和 2步长索引门限两个参数是由无线网络控制器通过 RRC层控制信 令配置给终端的。 其中， 3步长索引门限参数对应的是调度授权表一中的索 引， 2步长索引门限参数对应的是调度授权表一中的索引。 具体包括： 当终端接收到一个服务的相对授权（在冲突解决后的小区专用信道状 态或者小区前向接入信道状态）， 终端确定调度授权表一内大于等于参考功 率比的最小功率比， 确定该最小功率比在调度授权表一中的索引号， 将该 索引号记为调度授权（功率比）。 其中： 参考功率比为： 与这次数据传输具 有相同 HARQ 进程的前一个传输时间间隔所用于 E-TFC 选择的 E-DPDCH/DPCCH功率比。 此时，
当该服务的相对授权为 UP时， 如果调度授权（功率比）小于 3步长索 引门限， 则终端更新服务授权为 MIN (调度授权（功率比） +3 , 37)索引号对 应的调度授权表一中的调度授权； 如果调度授权（功率比） 小于 2 步长索 引门限， 且大于等于 3步长索引门限， 则终端更新服务授权为 MIN (调度授 权（功率比） +2 , 37)索引对应的调度授权表一中的调度授权； 如果调度授 权 (功率比）大于等于 2步长索引门限， 则终端更新服务授权为 MIN (调度 授权（功率比） +1 , 37)索引号对应的调度授权表一中的调度授权；
当该服务的相对授权为 DOWN时，终端更新服务授权为 MAX (调度授 权（功率比） -1 , 0)索引号对应的调度授权表一中的调度授权。
当终端接收到一个非服务的相对授权， 终端确定调度授权表一内大于 等于最大值的参考记录保存功率比的最小功率比， 确定该最小功率比在调 度授权表一中的索引号， 将该索引号记为调度授权（记录保存功率比）。 其 中， 参考记录保存功率比为： 与这次数据传输具有相同 HARQ进程的前一 个传输时间间隔所用于 E-TFC选择的 E-DPDCH/DPCCH功率比更新为新值 时所记录保存的这个新值。 此时，
当该非服务的相对授权为 DOWN时，终端更新服务授权为 MAX (调度 授权（记录保存功率比） - 1 , 0)索引号对应的调度授权表一中的调度授权。
步骤 102: 当终端进行 16QAM操作时， 终端使用绝对授权值映射关系 表二映射绝对授权， 并且， 终端使用调度授权表二更新服务授权。
本步骤中， 终端使用绝对授权值映射关系表二映射绝对授权为： 终端 接收到绝对授权的索引号后， 使用绝对授权值映射关系表二获取该此索引 号映射的绝对授权值。
终端使用调度授权表二更新服务授权为： 终端参照调度授权表二， 根 据相对授权转换为服务授权的算法来更新服务授权。在该算法中， 3步长索 引门限和 2步长索引门限两个参数是由无线网络控制器通过 RRC层控制信 令配置给终端的。 其中， 3步长索引门限参数对应的是调度授权表二中的索 引， 2步长索引门限参数对应的是调度授权表二中的索引。 具体包括：
当终端接收到一个服务的相对授权（在冲突解决后的小区专用信道状 态或者小区前向接入信道状态）， 终端确定调度授权表二内大于等于参考功 率比的最小功率比， 确定该最小功率比在调度授权表二中的索引号， 将该 索引号记为调度授权（功率比）。 其中： 参考功率比为： 与这次数据传输具 有相同 HARQ 进程的前一个传输时间间隔所用于 E-TFC 选择的 E-DPDCH/DPCCH功率比。 此时，
当该服务的相对授权为 UP时， 如果调度授权（功率比）小于 3步长索 引门限， 则终端更新服务授权为 MIN (调度授权（功率比） +3 , 37)索引号对 应的调度授权表二中的调度授权； 如果调度授权（功率比） 小于 2 步长索 引门限， 且大于等于 3步长索引门限， 则终端更新服务授权为 MIN (调度授 权（功率比） +2 , 37)索引对应的调度授权表二中的调度授权； 如果调度授 权 (功率比）大于等于 2步长索引门限， 则终端更新服务授权为 MIN (调度 授权（功率比） +1 , 37)索引号对应的调度授权表二中的调度授权； 当该服务的相对授权为 DOWN时，终端更新服务授权为 MAX (调度授 权（功率比） -1 , 0)索引号对应的调度授权表二中的调度授权。
当终端接收到一个非服务的相对授权， 终端确定调度授权表二内大于 等于最大值的参考记录保存功率比的最小功率比， 确定该最小功率比在调 度授权表二中的索引号， 将该索引号记为调度授权（记录保存功率比）。 其 中， 参考记录保存功率比为： 与这次数据传输具有相同 HARQ进程的前一 个传输时间间隔所用于 E-TFC选择的 E-DPDCH/DPCCH功率比更新为新值 时所记录保存的这个新值。 此时，
当该非服务的相对授权为 DOWN时，终端更新服务授权为 MAX (调度 授权（记录保存功率比） - 1 , 0)索引号对应的调度授权表二中的调度授权。
本发明方法中， 在终端实现授权时， 使用的反映绝对授权的绝对授权 值映射关系表与反映相对授权的调度授权表， 上限完全一致， 达到了绝对 授权和相对授权的完全覆盖； 而且这两个表的下限相隔 2个值， 在绝对授 权后， 实现了釆用一次相对授权命令达到更精细的调整。 通过本发明方法， 保证了通过快速调度来及时响应终端， 避免了由于授权调整造成的调度调 整方式的失败， 提升了 HSUPA技术在工程应用中的性能。

指令分析模块， 用于接收 RRC层控制信令， 根据信令中携带终端是否 进行 16Q AM操作的指示信息，在指示信息标识终端不进行 16QAM操作时， 向处理模块发送第一处理通知； 在指示信息标识终端进行 16QAM操作， 向 处理模块发送第二处理通知。
处理模块， 用于接收到来自指令分析模块的第一处理通知， 使用绝对 授权值映射关系表一映射绝对授权， 并且， 终端使用调度授权表一更新服 务授权； 接收到来自指令分析模块的第二处理通知， 使用绝对授权值映射 关系表二映射绝对授权， 并且， 终端使用调度授权表二更新服务授权。

步骤 302: 终端不进行 16QAM操作， 确定使用绝对授权值映射关系表 一映射绝对授权， 并且， 使用调度授权表一更新服务授权； 3步长索引门限 参数和 2步长索引门限参数对应的是调度授权表一中的索引。
步骤 303 : 参考功率比为： 终端保存有的、 与这次数据传输具有相同 HARQ进程的前一个 TTI所用于 E-TFC选择的 E-DPDCH/DPCCH功率比， 为（168/15)2。 终端确定调度授权表一内大于等于参考功率比 （168/15)2的最 小功率为（168/15)2,并进一步确定此最小功率比（168/15)2在调度授权表一中 的索引号为 29, 将该索引号记为调度授权（功率比）。
步骤 304: 终端接收到一个服务的相对授权 (在冲突解决后的小区专用 信道状态或者小区前向接入信道状态)为 UP,终端判断出调度授权（功率比） (取值为索引 29 ) 大于等于 2步长索引门限（取值为索引 20 ), 所以终端 更新服务授权为 MIN (调度授权（功率比） + 1 , 37 ) 索引对应的调度授权 表一中的调度授权。其中， MIN (调度授权（功率比） + 1 , 37)= MIN(29 + 1 , 37)= ΜΙΝ(30 , 37)=30 , 索引 30 对应的调度授权表一中的调度授权为 (95/15)2*4, 因此， 终端更新服务授权为（95/15)2*4。

步骤 403: 参考功率比为： 与这次数据传输具有相同 HARQ进程的前 一个 TTI所用于 E-TFC选择的 E-DPDCH/DPCCH功率比， 为（38/15)2。 终 端确定调度授权表一内大于等于参考功率比 （38/15)2 的最小功率为 (38/15)2,并进一步确定此最小功率比 (38/15)2在调度授权表一中的索引号为 16, 将该索引号记为调度授权（功率比）。
步骤 404: 终端接收到一个服务的相对授权（在冲突解决后的小区专用 信道状态或者小区前向接入信道状态）为 UP, 终端判断出调度授权（功率 比）（取值为索引 16 )小于 2步长索引门限（取值为索引 20 ), 且大于等于 3步长索引门限（取值为索引 3 ) , 因此， 终端更新服务授权为 MIN (调度授 权（功率比）+ 2 , 37)索引对应的调度授权表一中的调度授权。其中， MIN (调 度授权（功率比） + 2 , 37)= ΜΙΝ(16 + 2 , 37)= ΜΙΝ(18 , 37)=18, 索引 18对 应的调度授权表一中的调度授权为 (47/15)2 , 因此， 终端更新服务授权为 (47/15)2。

步骤 404: 终端接收到一个服务的相对授权（在冲突解决后的小区专用 信道状态或者小区前向接入信道状态）为 UP, 终端判断出调度授权（功率 比）（取值为索引 2 ) 小于 3步长索引门限（取值为索引 3 ), 因此， 终端更 新服务授权为 MIN (调度授权 (功率比 ) + 3, 37)索引对应的调度授权表一中 的调度授权。其中， MIN (调度授权（功率比）+ 3 , 37)= MIN(2 + 3, 37)= MIN(5 37)=5 , 索引 5对应的调度授权表一中的调度授权为（11/15)2, 因此， 终端更 新服务授权为（11/15)2。
