摘要： An apparatus and method for controlling a Hybrid Automatic Repeat reQuest (HARQ) operation in a transmitter of a wireless mobile communication system using each frame constituted by a plurality of subframes are provided. In the method for controlling an HARQ operation, indication information indicating a subframe position where transmission of a data burst starts and the number of subframes required for transmission of the data burst is transmitted to a receiver through an i-th frame. When the number of subframes does not exceed a threshold, it is determined that the data burst at the subframe position indicated by indication information of an (i+1)-th frame is retransmitted to the receiver. When the number of subframes exceeds the threshold, it is determined that the data burst at the subframe position indicated by indication information of an (i+n)-th frame, where n is a positive integer exceeding 1, is retransmitted to the receiver.

摘要： A method for handover by a Mobile Station (MS) in a wireless mobile communication system is provided. The MS receives from a serving Base Station (BS) an identifier and an interference level value of a neighboring BS. The MS determines a hysteresis margin value used for determining handover from the serving BS to the neighboring BS taking into account the interference level value of the neighboring BS. The MS sends a handover request to the serving BS when a difference between strength of a signal received from the neighboring BS and strength of a signal received from the serving BS exceeds the determined hysteresis margin value.
