Description

一种管理调制编码方式的方法和系统
技术领域
本发明涉及移动通信系统,尤其涉及一种管理调制编码方式(Modulation and Coding Scheme, MCS ) 的方法和系统。
背景技术
数字集群通信系统提供的最基本业务包括组呼业务和广播业务。 组呼业 务允许集群用户终端建立到属于某一给定区域某一组集群用户终端的群组呼 叫, 釆用半双工模式, 同一小区内的所有组内集群用户终端共享一条下行链 路, 抢占上行链路; 广播呼叫业务中只有呼叫发起方能够讲话, 其它都是听 者, 如果呼叫发起方退出呼叫, 则广播呼叫终止。 这两种业务的共同特点是: 组呼的非话权用户, 无无线资源控制 (Radio Resource Control, RRC )连接, 无专有信道, 共同监听群组下行广播信道; 单呼的话权 /非话权用户、 组呼的 话权用户, 基于 RRC 连接, 有专有信道, 类似普通长期演进(Long Term Evolution, LTE )用户。
因为无线信道的时变性,传统 LTE技术中釆用自适应调制编码(Adaptive Modulation Coding, AMC )方式, 使得系统通过动态改变编码方式和调制阶 数对链路变化进行自适应跟踪: 当信道条件较好时, 就会使用相对高阶的 MCS进行数据发送, 以提高系统吞吐量; 当信道条件较差时, 就会使用相对 低阶的调制编码方式来进行数据发送, 以保证传输可靠性。 传统 LTE实现自 适应调制编码方法是: 终端测量下行信道质量得到下行信号与干扰和噪声比 ( Signal to Interference plus Noise Ratio, SINR )值, 终端查询 SINR与 CQI 的映射表得到下行信道质量指示 ( Channel Quality Indicator, CQI ) , 并通过 上行 PUCCH( Physical Uplink Control Channel,物理上行控制信道)或 PUSCH ( Physical Uplink Shared Channel, 物理上行共享信道)上报给基站, 基站根 据上报的 CQI查询 CQI与 MCS的映射表得到 MCS的内环值;基站根据终端 上才艮的下行混合自动重传请求(Hybrid Automatic Repeat Request, HARQ )结 果计算误块率(Block Error Ratio, BLER ) ,再由 BLER的釆样值计算出 MCS 外环值。
基于传统 LTE技术的数字集群通信系统, 实现了传统集群业务。 由于传 统的 LTE技术是针对点对点的通信业务设计的, 而集群业务是一种点对多 点的业务, 因此, 集群业务特点决定集群数据传输中所釆用的 MCS也不同于 普通 LTE技术, 表现如下:
集群用户的下行数据传输是没有 HARQ反馈的, 因此基站无法获知终端 的误包率, 无法获得 MCS外环值; 集群中非话权用户没有上行通道, 因此不 能使用普通 LTE用户上报 CQI的过程; 群组用户是分散的, 分布比较随机, 必须保证群组中每个用户都能可靠地解调出编码信息; 群组中每个终端用户 都会上报 CQI, 基站必须合理处理群组多个终端上报的 CQI信息。
这些特点决定目前 LTE中使用的调制编码方法不适用于基于 LTE技术的 数字集群通信系统。

附图概述
以及
图 3为本发明实施例提供的管理调制编码方式的系统的结构示意图。 本发明的较佳实施方式
下面将结合附图对本发明实施例作详细描述。 需要说明的是, 在不冲突 的情况下, 本申请中的实施例及实施例中的特征可以相互任意组合。
图 1所示, 所述方法包括如下步骤:
步骤 101、 基站获取集群终端的误块率达到预先存储的误块率门限时的 下行 CQI。
步骤 102、 基站将接收的 CQI与本地保存的群组上报 CQI进行比较, 其 中所述群组上报 CQI为已接收到的群组中各集群终端上报的 CQI 中的最小 值。
步骤 103、 如果比较结果为群组当前 CQI小于群组上报 CQI, 基站发起 更新 MCS值的操作。
本发明实施例提供的方法中, 针对数字集群系统, 基于 LTE无线协议基 础上, 提出了一种基于 LTE技术的集群系统自适应调制编码方案, 能够动态 自适应调整群组数据传输时所使用的调制编码方案, 保证集群业务数据可靠 有效地传输, 进而提高系统容量。
通过操作维护中心( Operation Maintenance Center, OMC )配置管理参数, 如,上报 CQI状态报告的 BLER门限、避免频繁触发 CQI上报的定时器时长、 MCS外环调度计数器阔值、 以及群组初始 CQI等参数,在由基站通过群组承 载控制消息将 BLER门限和避免频繁触发 CQI上报的定时器时长参数带给集 群终端; 在接收到上述参数后, 集群终端实时检测自己的 BLER, 当 BLER 站接收集群终端上报的 CQI及 MCS,并根据上报的 CQI确定群组调度时 MCS 内环值, 根据上报 CQI及 MCS确定群组调度时的 MCS外环值, 进而根据 MCS内环值和 MCS外环值确定最终调度时的群组 MCS。
为了有效控制集群终端上报 CQI的频率, 所述方法还包括:
集群终端在本地的误块率达到预先存储的误块率门限时, 在进行 CQI上 报后, 启动用于禁止上报的定时器, 用以控制在定时器到时前不再向基站发 送 CQI信息; 以及
在用于禁止上"¾的定时器到时后, 如果本地的误块率仍大于所述误块率 门限, 集群终端继续向基站发送 CQI信息。
其中, 所述基站发起更新 MCS值的操作包括:
将群组当前 CQI更新为群组上才艮 CQI; 以及
在预先存储的群组 CQI与 MCS的映射表, 查询群组当前 CQI对应的数 值, 将查询得到的数值作为 MCS内环值。
上面对如何确定 MCS内环值进行了说明,本领域技术人员可以釆用其他 方式确定 MCS外环值, 最终得到 MCS值。 下文提供了一种如何确定 MCS 外环值的方式, 该方式说明如下。
其中, 所述基站发起更新 MCS的操作包括:
如果群组上报 MCS小于或等于群组 MCS,则所述基站将群组 MCS外环 值降一阶,其中,群组上报 MCS为集群终端的误块率达到预先存储的误块率 门限时上 ^艮的 CQI对应的 MCS的最小值,群组 MCS为上次被调度时所确定 的 MCS;
如果群组外环调度次数计数器达到预先设置的 MCS 外环调度计数器阔 值, 则所述基站将群组 MCS外环值升一阶, 并将群组外环调度次数计数器清 零; 其中, 在更新后的群组上报 CQI在预先存储的群组 CQI与 MCS的映射 表对应的 MCS小于群组 MCS, 或者, 群组上报 MCS小于或等于群组 MCS 时, 群组外环调度次数计数器清零; 在每次基站周期性调度 MCS值时, 群组 外环调度次数计数器加一; 以及
根据调整后的 MCS外环值, 确定本次调度的 MCS值。
同理,上面对如何确定 MCS外环值进行了说明,本领域技术人员可以釆 用其他方式确定 MCS内环值, 当然, 也可以釆用上文提供的 MCS内环值获 取方法, 进而最终得到 MCS值。
为了简化集群终端的处理流程, 所述集群终端的误块率达到预先存储的 误块率门限时上报的 CQI对应的 MCS值是同集群终端上报的 CQI—起发送 的。
下面对本发明实施例提供的方法作详细说明。 如图 2所示, 所述方法包含以下步骤 201~207:
步骤 201 , OMC配置触发集群终端的上报 CQI状态报告的 BLER门限、 避免频繁触发 CQI上报的定时器时长、 MCS外环调度计数器阔值、 以及群组 初始 CQI等参数。
1 ) 、 OMC配置触发集群终端的上报 CQI状态报告的 BLER门限、 避免 频繁触发 CQI上报的定时器时长、 MCS外环调度计数器阔值、群组初始 CQI、 以及群组初始 MCS外环值等参数;
2 )、基站的群组 CQI管理模块及群组 MCS管理模块获取上述配置信息。 步骤 202 ,基站通过群组承载控制消息将 BLER门限和避免频繁触发 CQI 上报的定时器时长参数带给终端。 1 ) 、 基站将 BLER 门限和避免频繁触发 CQI上报的定时器时长参数编码到群组承载控制消息中;
2 )、 基站周期性发送群组承载控制消息, 保证群组迟后接入终端的正确 接收;
3 )、 集群终端接收群组承载控制消息, 并获取 BLER门限和避免频繁触 发 CQI上报的定时器时长参数。
步骤 203 , 集群终端实时检测自己的 BLER , 当 BLER达到规定的门限, 集群终端接收群组数据并实时监测 BLER;
若监测到 BLER超过门限, 集群终端通过随机接入过程上报状态报告, 该状态 ^艮告包括 BLER对应的 CQI及 MCS;
为避免集群终端频繁上报自己的状态, 集群终端满足 BLER触发的同时 还需要满足 CQI上报间隔保护。 CQI上报一次之后将启动用于禁止上报的定 时器, 定时器时长即为上述通过承载控制消息传递给终端的避免频繁触发 CQI上报的定时器时长参数, 定时器超时前不能再进行 CQI上报。
步骤 204, 基站接收集群终端上 ^艮的 CQI及 MCS。
基站解调随机接入的 MSG3 (第三条消息 )获取上报的 CQI和 MCS, 并 传递给群组 CQI管理模块;
群组 CQI管理模块包括群组 CQI、 群组上报 CQI、 群组 MCS、 群组上报 MCS四个属性, 其中:
群组 CQI属性用于群组被调度时计算 MCS内环值, 群组 CQI的初始值 由步骤 201中群组初始 CQI参数确定; 群组 MCS保存群组上次被调度时所 确定的 MCS; 群组上报 CQI保存群组中各终端上报的 CQI最小值, 在后续 计算群组 MCS时作为群组 CQI 的候选;群组上报 MCS保存群组中各终端上 报的 MCS最小值, 用于后续计算群组 MCS外环值;
群组 CQI管理模块收到上报的 CQI和 /或 MCS, 判断其是否小于群组上 报 CQI和 /或 MCS, 如果小于, 则更新群组上报 CQI和 /或 MCS, 如果大于, 则丟弃不作处理。
步骤 205, 基站根据上报的 CQI确定群组调度时的 MCS内环值。
群组调度时确定群组 CQI的方法是:
群组 MCS管理模块依据群组 CQI管理模块输出的群组 CQI, 查询群组 CQI与 MCS的映射表, 得到群组 MCS内环值。
步骤 206,基站根据上报的 CQI及 MCS确定群组调度时的 MCS外环值。 照下面步骤进行: 步骤 a、 群组 CQI管理模块依据群组上报 CQI查询群组 CQI与 MCS的 映射表, 获取一个 MCS, 若此 MCS小于群组 MCS, 则将群组外环调度次数 计数器清零。
步骤 b、 群组 MCS 管理模块判断群组 CQI 管理模块输出的群组上报 MCS,如果群组上报 MCS小于等于群组 MCS,则将群组 MCS外环值降一阶, 即数值减一。
步骤 c、 在每次基站周期性调度 MCS值时, 群组外环调度次数计数器加 一,群组 MCS管理模块判断群组外环调度次数计数器是否达到 MCS外环调度 计数器阔值, 如果达到, 则将群组 MCS外环值升一阶, 并将群组外环调度次 数计数器清零; 如果未达到, 则群组 MCS外环值不作变化。
步骤 207, 基站计算最终调度时群组 MCS。
群组 MCS管理模块确定群组调度时的最终 MCS, 即,群组 MCS内环值 与 MCS外环值之和;
群组 MCS管理模块输出群组 MCS给下行数据调度模块。
