Description

一种半静态调度重激活的方法及基站
技术领域
本发明涉及无线通讯领域， 尤其涉及一种半静态调度重激活的方法及基 站。
背景技术
如图 1 所示， LTE ( LTE, long term evolution ) 系统主要由终端 （User Equipment, UE ) 、 基站（eNB )和核心网组成。 eNB负责接入层事务， 如无 线资源管理等， 上下行无线资源按共享信道的方式由 eNB负责调度。 核心网 负责非接入层事务， 如计费、 位置管理等。 每个 UE在上行方向通常只能连 接到网络中的一个 eNB。
在现有 LTE系统中，对于上行和下行共享信道，釆用 eNB调度的方式来 控制不同 UE的上行和下行传输， 以提高信道的利用率。 eNB有两种调度方 式： 半静态调度（Semi-Persistent Schedule, SPS )和动态调度。
半静态调度是指： 为特定业务设计的、 需要激活 /重激活 /释放资源的、 在 方法。
半静态调度的原理如图 2所示。 半静态调度釆用 SPS数据来触发 SPS激 活， 基站通过专用的物理下行控制信道 ( Physical Downlink Control Channel, PDCCH ) 向 UE发送为其预分配的资源信息， 以激活 UE。 在半静态调度周 期内， 该 UE会使用 eNB为其预分配的静态资源来传输数据。 当 SPS数据大 小发生较大变化， 或信道质量发生较大变化时， eNB会进行 SPS重激活， 利 用 PDCCH向该 UE发送为其重新预分配的资源信息， 而该 UE会使用 eNB 为其重新预分配的静态资源来传输数据。 其中， 上行 SPS和下行 SPS的激活 和重激活都是独立的， SPS重激活不宜频繁发生。
在半静态调度周期内， UE在使用该 eNB为其预分配的静态资源来传输 数据时， 若有其他的并发业务， 则应禁止在同一个传输时间间隔 （ΤΉ, transmission time interval ) 内传输该并发业务。 在半静态调度周期内， UE需 要监测 PDCCH, 如果没有监测到属于本 UE的控制信息， 则釆用静态的 SPS 参数， 此时该 UE 的控制信道不发送， 以节约资源； 如果监测到属于本 UE 的重激活控制信息，则保存并使用重激活的 SPS参数；如果监测到属于该 UE 的动态资源分配控制信息， 则解析该控制信息， 对动态数据进行解码。
动态调度是指 eNB在每个 TTI为 UE动态分配资源， 并通过 PDCCH通 知 UE; UE通过监测 PDCCH来发现可能的动态资源。
在上行方向， UE是数据的发送端， 调度器位于 eNB。 UE通过向 eNB发 送緩存状态报告 ( Buffer Status Report, BSR )以通知服务 eNB其上行緩存中 的数据总量。 eNB根据 UE向其发送的 BSR及当前信道质量等信息进行调度， 为每个 UE分配资源。
UE以逻辑信道组（ Logical Channel Group, LCG )为单位向服务 eNB发 送 BSR。 LTE中共有四个 LCG。 可以将 SPS业务专门划分到同一个 LCG, 也可以划分到不同的 LCG。 当 SPS业务被划分到不同 LCG时， SPS业务有 可能和动态调度业务共存于同一个 LCG。
eNB是根据收到的 BSR获得 UE待发送的数据量信息的。 当 SPS业务和 动态调度业务被划分到同一个 LCG时，该 LCG的 BSR会同时包含 SPS业务 和动态调度业务的数据量， 因此此时 eNB就无法根据收到的 BSR区分 SPS 业务和动态调度业务的数据量。所以， UE不能通过 BSR通知 eNB其上行 SPS 数据的变化情况。 当 UE的上行 SPS数据在一段时间内发生变化时， eNB也 就无法进行上行 SPS重激活， 从而导致持续的空口资源浪费或分配给 UE的 空口资源不足的情况。
发明内容

附图概述

图 2为现有技术中半静态调度原理示意图；
图 3为本发明实施例中上行 SPS数据变大时， SPS重激活的流程示意图； 图 4为本发明实施例中上行 SPS数据变小时， SPS重激活的流程示意图； 图 5为本发明实施例中半静态调度重激活的基站结构图。
本发明的较佳实施方式
下面将结合附图及实施例对本发明的技术方案进行更详细的说明。
本发明所述方法的基本构思是： 被激活半静态调度的 eNB在为 UE预分 配资源后， 保存该预分配的传输块的大小信息； eNB在收到该 UE上传的完 整的 SPS数据包后， 将该数据包的大小与其上保存的预分配的传输块的大小 进行比较， 并在二者大小不相等的情况下重激活半静态调度。
在重激活半静态调度后， 该 eNB重新为该 UE预分配资源， 并将其上保 存的预分配的传输块的大小信息更新为此次预分配的传输块大小信息。
其中，完整的 SPS数据包大小可以等于 eNB 无线链路控制协议（ radio link control, RLC ) 的业务数据单元（ Service Data Unit, SDU ) 的长度； 或者等 于 eNB分组数据汇聚协议 ( acket data convergence protocol, PDCP ) 的协议 数据单元（Protocol Data Unit, PDU ) 的长度。
此外， 为了防止由于单个数据包过大或过小而造成的频繁触发重激活半 静态调度的情况， 可在 eNB中预设一比较周期， 则 eNB在收到该 UE上传的 完整的 SPS数据包后， 将该数据包的大小与其上保存的预分配的传输块的大 小进行比较， 并在二者大小不相等的情况下重激活半静态调度是指： eNB分 别对在该比较周期内从上述 UE收到的各完整的 SPS数据包大小与其上保存 的预分配的传输块的大小进行比较， 当各完整的 SPS数据包大小都与其上保 存的预分配的传输块的大小均不相等时， 重激活半静态调度。 其中， 该比较 周期的值大于 2个半静态调度周期的值。
为了进一步抑制频繁重激活半静态调度，还可以在 eNB中预设一门限值， eNB只有当判断出在该比较周期内从上述 UE收到的各完整的 SPS数据包大 小与其上保存的预分配的传输块的大小的差值的绝对值均大于等于上述门限 值时， 才重激活半静态调度。 其中， 门限值的取值与 SPS业务类型及具体的 业务特性有关。
下面用本发明的两个应用实例进一步加以说明。
实施例 1 : 上行 SPS数据变大时， 重激活 SPS。

步骤 1.4、在比较周期内，所收到的所有数据包的偏差△均大于等于预设 门限值，则 eNB进行上行半静态调度重激活， 重新为 UE预分配较多的资源， 保存新的预分配的传输块大小为参考值 R; 步骤 1.5、 UE在半静态调度周期使用重新预分配的资源发送上行 SPS数 据。
实施例 2: 上行 SPS数据变小时， SPS重激活
SPS业务和动态调度业务共存且划分到同一个 LCG的 UE, 上行 SPS数 据变小时， SPS重激活的过程如图 4所示， 包括以下步骤：
步骤 1.1、 eNB激活上行半静态调度， 周期性的为 UE预分配资源， 保存 预分配的传输块大小作为参考值 R;
步骤 1.2、 UE在半静态调度周期使用预分配资源发送上行 SPS数据； 步骤 1.3、 eNB收到完整的上行 SPS数据包，记录 RLC SDU或 PDCP PDU 的长度 L, 且 L < R, 偏差 A =R - L;
步骤 1.4、在比较周期内，所收到的所有数据包的偏差△均大于等于预设 的门限值， 则 eNB进行上行半静态调度重激活， 重新为 UE预分配较少的资 源， 保存新的预分配的传输块大小为参考值 R;
步骤 1.5、 UE在半静态调度周期使用重新预分配的资源发送上行 SPS数 据。

资源分配模块设置成为 UE预分配资源后， 将该预分配的传输块的大小 信息发送到存储模块； 存储模块设置成保存接收到的预分配的传输块的大小 信息； 数据包接收模块设置成在收到 UE上传的完整的半静态调度数据包后， 将该数据包的大小信息发送到比较模块； 比较模块设置成比较接收到的完整 的半静态调度数据包与预分配的传输块的大小， 并在二者大小不相等的情况 下向资源分配模块发送重激活半静态调度指令。 其中， 完整的半静态调度数 据包的大小等于 eNB 无线链路控制协议的业务数据单元的长度， 或者等于 eNB分组数据汇聚协议的协议数据单元的长度。
资源分配模块还设置成在收到重激活半静态调度指令后， 重新为该 UE 预分配资源， 并将此次预分配的传输块大小信息发送给存储模块； 存储模块 还用于将本地保存的预分配的传输块的大小信息更新为接收到的此次预分配 的传输块大小信息。 另外， 存储模块中预设有一比较周期；
比较模块设置成比较接收到的所述完整的半静态调度数据包与所述预分 配的传输块的大小， 并在二者大小不相等的情况下向所述资源分配模块发送 重激活半静态调度指令是指：所述比较模块分别对在该比较周期内从上述 UE 收到的各完整的半静态调度数据包的大小与所述存储模块中保存的预分配的 传输块的大小进行比较， 当判断出各完整的 SPS数据包大小都与所述预分配 的传输块的大小均不相等时， 向所述资源分配模块发送重激活半静态调度指 令。
所述存储模块中还预设一门限值； 比较模块设置成比较接收到的所述完 整的半静态调度数据包与所述预分配的传输块的大小， 并在二者大小不相等 的情况下向所述资源分配模块发送重激活半静态调度指令是指： 所述比较模 块分别对在该比较周期内从上述 UE收到的各完整的半静态调度数据包的大 小与所述存储模块中保存的预分配的传输块的大小进行比较， 当判断出各完 整的 SPS数据包大小都与所述预分配的传输块的大小的差值的绝对值均大于 等于所述门限值时， 向所述资源分配模块发送重激活半静态调度指令。
当然， 本发明还可有其他多种实施例， 在不背离本发明精神及其实质的 但这些相应的改变和变形都应属于本发明所附的权利要求的保护范围。
工业实用性
与现有技术相比， 本发明解决了 SPS业务和动态调度业务共存且划分到 同一个 LCG的 UE, 上行 SPS数据在一段时间内发生变化时， eNB无法进行 上行 SPS重激活的问题， 使空口资源的分配更加合理。
