    • PROBLEM TO BE SOLVED: To provide a digital wireless communication system that reduces scheduling and ARQ delay. SOLUTION: A base station 301 schedules one mobile station 104 based upon scheduling information 402 and a link quality measure received from each mobile station 1014, and decodes first data received from the scheduled mobile station 1014. If the decoding ends in failure, the base station 301 rereceives data from the scheduled mobile station 1014 and puts the rereceived data together with previously received data to generate composite data. In this case, the generation of composite data is performed until the decoding of the composite data is successful or batch erasure of a hybrid automatic retransmission request (H-ARQ) buffer is performed. When decoding of one of the first data and composite data is successful, an acknowledgement signal is transmitted to the mobile station 1014 and batch erasure of the H-ARA is performed in response to the acknowledgement signal.

    • PROBLEM TO BE SOLVED: To provide a method for scheduling asynchronous transmission for a plurality of subscriber units, which reduces an amount of overlap and/or gap of transmission segments between the subscriber units.SOLUTION: The method of scheduling asynchronous transmission includes a step (305) of receiving information associated with a plurality of subscriber units that have uplink data to transmit and the information includes uplink timing offset information associated with each of the subscriber units. Two or more subscriber units are selected from a plurality of subscriber units having a timing offset differential that is below a predetermined threshold value (310). The timing offset differential is a difference in timing offset between the subscriber units, and is minimized by being offset by a multiple of the transmission segment size. The transmission segments of data are allocated (315) to the selected two or more subscriber units.

    • PROBLEM TO BE SOLVED: To provide a digital wireless communication system for reduction of scheduling and ARQ delay. SOLUTION: An up-link transmission scheduling method includes a step for receiving scheduling information 402 from a mobile station 1014 with a base station 301, 303, and 304 in an active set. The scheduling information has at least one of the queue status and electrical power status of the mobile station. The method also includes a step for determining up-link channel scheduling assignment 418 with the base station in the active set by utilizing the scheduling information and at least any one of a base station interfrometer amount and link quality, which correspond to the mobile station. The method still further includes steps for transmitting up-link channel scheduling assignment 418 containing a maximum power margin target with the base station in the active set and for receiving a selection instruction 416 of the modulated encoding system of up-link transmission based on the maximum power margin target from the mobile station with the base station in the active set.

    • PROBLEM TO BE SOLVED: To provide an efficient signal system for supporting the high speed uplink packet access service (HSUPA) for relieving a resource usage amount and an arithmetic processing load.
      SOLUTION: A cellular communication system (100) comprises a first base station (103) which schedules resource for a user equipment (101). When receiving a resource allocation message, the user equipment (101) transmits a first message comprising a transmit indication to a plurality of base stations (103 to 109) wherein the transmit indication is indicative of a subsequent transmission of a second message. The user equipment (101) then proceeds to determine a transmit format for the second message; and to transmit the second message to the plurality of base stations (103 to 109). When receiving the transmit indication, the plurality of base stations (103 to 109) proceed to configure their receivers to receive the second message. The first message may be transmitted in a control channel and the second message may be transmitted in a user data channel.
