    • The present invention relates to a method and apparatus for requesting bandwidth in a wireless communication system. According to one aspect of the present invention, a method in which a mobile terminal makes a request for bandwidth in a wireless communication system is configured such that the mobile terminal receives, from a base station, information on whether or not the base station can compensate for changes in the bandwidth request quantity caused by the fragmentation or packing of a protocol data unit (PDU), the mobile terminal makes a request, to the base station, for bandwidth required for transmitting a first PDU, the mobile terminal separates the first PDU and generates a second PDU and a third PDU in consideration of the quantity of allocated bandwidth when the quantity of bandwidth allocated by the base station is smaller than the requested quantity, the mobile terminal transmits the second PDU to the base station, and the mobile terminal starts a first timer at the point in time the bandwidth allocation is received or at the point in time when the second PDU is transmitted, if said information indicates that the base station can compensate for changes in the bandwidth request quantity caused by the fragmentation or packing of a PDU.
    • 本发明涉及一种在无线通信系统中请求带宽的方法和装置。 根据本发明的一个方面,移动终端在无线通信系统中请求带宽的方法被配置为使得移动终端从基站接收关于基站是否可以补偿的信息 对于由协议数据单元(PDU)的分段或打包引起的带宽请求量的变化,移动终端向基站请求发送第一PDU所需的带宽,移动终端将第一PDU分离 并且当基站分配的带宽量小于所请求的数量时,考虑到分配的带宽的数量生成第二PDU和第三PDU,则移动终端向基站发送第二PDU,并且移动终端 在接收到带宽分配的时间点或在发送第二PDU的时间点上启动第一定时器,如果所述信息 表示基站可以补偿由PDU的分段或打包引起的带宽请求量的变化。

    • A method for retransmitting data using an HARQ method and a mobile station using the same in a wireless telecommunications system are disclosed herein. When all bits of a resource index field in an uplink basic assignment A-MAP received from a base station through a specific frame are set to 1, the mobile station may not retransmit an HARQ sub-packet from an uplink subframe within the specific frame. In this case, the mobile station may retransmit an HARQ sub-packet from an uplink subframe within a frame subsequent to the specific frame. At this point, the uplink subframe and resource index of the subsequent frame respectively correspond to the subframe and resource index having the same index and resource index of an uplink subframe predetermined in association with the retransmission of the mobile station in a previous frame. The resource index corresponds to information indicating where the assigned resource is positioned within the corresponding subframe and how large the size of the assigned resource is. Alternatively, the mobile station may receive once again the uplink basic assignment A-MAP, so as to retransmit the HARQ sub-packet from an uplink subframe designated by the uplink basic assignment A-MAP.
    • 本文公开了一种使用HARQ方法重传数据的方法和在无线电信系统中使用该方法的移动台。 当从基站通过特定帧接收的上行链路基本分配A-MAP中的资源索引字段的所有比特被设置为1时,移动台可以不从特定帧中的上行链路子帧重发HARQ子分组。 在这种情况下,移动台可以在特定帧之后的帧内的上行链路子帧中重传HARQ子分组。 此时,后续帧的上行子帧和资源索引分别对应于与前一帧中的移动台的重发相关联地预定的上行链路子帧的索引和资源索引相同的子帧和资源索引。 资源索引对应于指示分配的资源位于相应子帧内的位置以及所分配的资源的大小多大的信息。 或者,移动台可以再次接收上行链路基本分配A-MAP,以便从由上行链路基本分配A-MAP指定的上行链路子帧重传HARQ子分组。
