Description

一种上行混合自动重传请求的调度方法与系统
技术领域
本发明涉及通信领域, 具体地说, 涉及一种上行混合自动重传请求 ( HARQ, Hybrid Automatic Retransmission Request ) 的调度方法与系统。
背景技术
混合自动重传请求 (HARQ )是一种为克服无线移动信道时变和多径衰 落对信号传输的影响而提出的技术, 该技术是通过将自动重传请求(ARQ, Automatic Retransmission Request ) 和前向纠错编码 ( FEC , Forward Error Correction )这两种技术联合使用来实现的。 HARQ技术能够使无线移动通信 系统获得更高的系统吞吐量和更高的系统稳定性,并且是 3G长期演进( LTE, Long Term Evolution ) 系统以及全球微波接入互操作性(WiMAX , World Interoperability for Microwave Access ) 系统中的关键技术之一。
在 TDD-OFDM ( Time Division Duplex-Orthogonal Frequency Division
Multiplexing, 时分双工正交频分复用) 系统中, 上、 下行是分时传输的, 该 系统中的基站和终端收到对方的数据都需要一定的处理时间, 另外由于帧对 齐和传播也会引入的一定的时延, 为了减少 TDD-OFDM 系统固有的时间延 迟, TDD-OFDM系统通常将用于数据传输的无线帧( Radio Frame )分为几个 更小的子帧(Sub-Frame ) , 包括下行子帧和上行子帧, 下行子帧和上行子帧 的比例可以根据具体实施情况而确定; 如图 1所示, 一个无线帧分为 8个子 帧(SF0-SF7 ) , —个无线帧内有一对上下行切换点, 图 1中 UL/DL (上行子 帧 /下行子帧) 的比例为 3: 5。
在现有的技术方案中, 如图 2所示, 一种上行 HARQ通信过程, 又称为 HARQ进程, 可以描述:
步骤 S201 , 基站通过控制信道上的控制信令给终端分配发送数据的上行 子帧的资源, 终端在所分配的上行子帧的资源上向基站发送初传数据或重传 数据, 开始 HARQ进程; 步骤 S202, 基站接收来自终端的初传数据或重传数据, 并在相应的反馈 信道中将反馈信息发送给终端, 如果反馈信息是否认信息 (NACK ) , 则执 行步骤 S203; 如果反馈信息是确认信息 (ACK ) , 则执行步骤 S204;
步骤 S203 , 终端接收否认信息, 判断对数据的重传是否达到最大重传次 数, 如果达到重传次数, 则执行步骤 S204; 否则, 终端在 HARQ进程规定的 重传间隔要求下,执行步骤 S201 ,在相应的上行子帧的资源上进行重传数据; 步骤 S204, 终端终止 HARQ进程, 结束。
在 TDD-OFDM系统下, 突发业务与正在进行的上行 HARQ进程中的控 制信道和 /或反馈信道相冲突, 使得控制或反馈信道的所在的资源存在不可用 的情况。 例如当多播广播业务(MBS, Multicast and Broadcast Service ) /增强 的多播广播业务 ( E-MBS, Enhanced Multicast and Broadcast Service )以 TDM (时分复用) 方式与单播业务复用资源时, 由于多播广播业务是非周期性调 度的, 多播广播业务会临时占用下行子帧的资源, 使得位于所述下行子帧上 的控制信道和 /或反馈信道将不可用 , 这样使得发送端不能正确获得相应的控 制信息和 /或反馈信息。 如图 3所示, 在 TDD-OFDM系统下连续两个无线帧 N、 N+1中, 控制信道 /反馈信道以间隔 1个子帧的方式分布, 如图中下行子 帧 U0、 Ul和 U2与上行子帧 SF5、 SF6和 SF7分别——对应, 下行子帧 U0、 Ul和 U2是上行子帧 SF5、 SF6和 SF7的控制信道和 /或反馈信道, 多播广播 业务以 TDM方式与单播业务复用,占用了无线帧 N+1中下行子帧 SF3和 SF4, 无线帧 N+1中的反馈信道 U2用于承载着无线帧 N中的上行子帧 SF7的反馈 信息, 由于无线帧 N+1中的下行子帧 SF4被占用, 所以不能在下行子帧 SF4 上发送; 因此, 在无线帧 N中子帧 SF7上发送数据的终端得不到反馈信息, 而无线帧 N+1的 SF7将处于控制空缺状态。

本发明的较佳实施方式
以下对具体实施方式进行详细描述, 但不作为对本发明的限定。
如图 4所示, 为本发明实施例所述的克服上行混合自动重传请求与突发 业务冲突的方法,应用于 TDD-OFDM系统的基站与终端间进行的上行 HARQ 进程中, 具体步骤包括:
步骤 101 , 基站对用于上行 HARQ进程的每个超帧内的无线帧进行顺序 标号 , 并对超帧中作为控制信道或反馈信道的下行子帧进行标号。
其中, 该步骤 101之前基站是根据预定信息对每个超帧内的无线帧中的 上行子帧设置与其关联的控制信道和反馈信道, 通过上述设置基站与终端间 进行上行 HARQ进程; 所述预定信息包括: 一个超帧内的无线帧中上行子帧 和下行子帧的数量之比、 控制信道或反馈信道的分布、 上 /下行的处理时延。
所述设置具体是基站根据预定信息将超帧内每个上行子帧与该上行子帧 之前的一个下行子帧关联作为该上行子帧的控制信道, 与该上行子帧之后的 一个下行子帧关联作为该上行子帧的反馈信道。
这里所述控制信道为承载调度该上行子帧发送数据信息的时频资源; 所 述反馈信道为终端通过该上行子帧发送数据信息给基站后, 基站根据上行 HARQ技术用于发送的确认(ACK )信息或否定(NACK )信息的时频资源。
步骤 102, 当有突发业务产生并使基站和终端间正在进行的上行 HARQ 进程中的一个或多个上行子帧所关联的控制信道和 /或反馈信道不可用时, 基 站根据关联关系的改变原则得到这些上行子帧新关联的控制信道和 /或反馈 信道, 并将上行子帧的标号、 改变后的这些上行子帧新关联的控制信道和 /或 反馈信道的标号, 以及这些上行子帧新的关联关系的有效持续时间组成广播 消息 (该广播消息中的信令格式如表 2所示) , 将该广播消息写入超帧头中 通过广播信道发送给终端。
其中, 所述有效持续时间为在基站内预先设置的基站和终端间在几个超 帧中根据改变后的这些上行子帧新的关联关系进行上行 HARQ进程, 如在基 站内没有预先设置有效持续时间的时长, 则该有效持续时间默认为一个超帧 的时长;
其中, 所述关联关系的改变原则是:
基站将上行子帧所关联的不可用的控制信道改为该控制信道之前可用的 控制信道, 将上行子帧所关联的不可用的反馈信道改为该反馈信道之后可用 的反馈信道。
这里后续实施例 1 - 3釆用的是:基站将上行子帧所关联的不可用的控制 信道改为该控制信道之前相邻最近的可用的控制信道, 将上行子帧所关联的 不可用的反馈信道改为该反馈信道之后相邻最近的可用的反馈信道。
步骤 103 , 终端读取超帧头中的广播消息, 并按照广播消息中上行子帧 的标号、 改变后的所述上行子帧新关联的控制信道和 /或反馈信道的标号确定 上行子帧新关联的控制信道和 /或反馈信道, 然后基站和终端均根据该上行子 帧新关联的控制信道和 /或反馈信道进行上行 HARQ进程,在有效持续时间结 束后, 基站和终端均对改变关联的控制信道和 /或反馈信道的上行子帧恢复到 预先设置所关联的控制信道和 /或反馈信道上继续进行上行 HARQ进程。
这里本发明实施例方法中所述的突发业务为多播广播业务或者增强的多 播广播业务。
根据本发明所述的方法实施例 1
如预定信息是: 1、 超帧包含有 4个无线帧, 一个无线帧包含 8个子帧, 上下行子帧分配比例为 3: 5; 2、 上行处理时延和下行处理时延均为 2个子 帧的时长; 3、 与上行子帧关联的控制信道或反馈信道在超帧中是每间隔一个 无线帧中的下行子帧分布的; 根据本发明所述的方法, 具体步骤是:
步骤 1 , (如图 5所示)基站对一个超帧中的无线帧进行顺序标号, 比 如: SF0 SF31 ; 并对超帧中作为控制信道或反馈信道的下行子帧进行标号, 比 ¾。U0, Ul , U2...0
现有的根据预定信息对每个上行子帧设置与其关联的控制信道和反馈信 道, 如表 1所示, 在一个超帧中每个上行子帧与其关联的控制信道和反馈信 道对应关系表:
表 1
Figure imgf000012_0001
与该上行子帧关联的反馈信道上进行 ACK/NACK信息的反馈,从而使终端决 定其是否重传。
步骤 2, 当系统在下行子帧 SF11、 SF12上调度了多播组播业务, 位于下 行子帧 SF12上的控制信道或反馈信道 U5不能在预定的资源上发送控制信息 或反馈信息, 基站根据设置的关联关系的改变原则, 将 SF7关联的反馈信道 从 U5改为 U6, 将 SF15关联的控制信道从 U5改为 U4; 由于多播组播业务 的调度是以超帧为周期, 因此基站将改变后的这些上行子帧与控制信道和 /或 反馈信道的新的关联关系, 以及这些上行子帧新的关联关系的有效持续时间 组成广播消息, 并将该广播消息写入超帧头中通过广播信道发送给终端; 如表 2所示, 为广播消息的信令格式的表示;
表 2
Figure imgf000013_0001
其中, 如广播消息的信令格式中的有效持续时间没有设置, 则该有效持 续时间釆用默认的一个超帧的时长。
与表 1相对应的表 3是当上行子帧的控制信道和 /或反馈信道不可用时, 根据关联关系的改变原则, 改变后的一个超帧中每个上行子帧与其关联的控 制信道和反馈信道对应关系表, 通过表 1和表 3的对比更加直观的看出根据 关联关系的改变原则所改变的部分(如表 3所示, 其中下划线的部分为上行 子帧新的关联信道) ;
