Patent ID: 8014349

Claim:
A method for transmitting a signal by a base station (BS) in a communication system, the method comprising: allocating a quasi-dedicated control channel (QDCCH) to a first mobile station (MS); temporarily allocating the QDCCH as a temporary uplink channel (TULCH), to a second MS for a preset time, when the first MS does not need to use the QDCCH, and after temporarily allocating the QDCCH to the second MS, transmitting information indicating the allocation of the QDCCH to the second MS, to the first MS and the second MS, wherein the preset time is set within a bound satisfying at least one of a maximum allowable delay time of the first MS and a quality-of-service (QoS) of a service received by the first MS, wherein the QDCCH is used for one of Channel Quality Information Channel (CQICH) allocation and uplink resource allocation for at least one service to require data transmission over an uplink, wherein the preset time excludes a Channel Quality Information (CQI) feedback period for which the first MS feeds back CQI, if the QDCCH is used to the CQICH allocation, and the preset time excludes an interval in which the first MS transmits a request for the uplink resources allocation to the BS, if the QDCCH is used to the uplink resources allocation, and wherein a maximum number of QDDCHs allocable as the TULCH is determined based on a total number of QDCCHs allocated by the BS and a session access delay value of each MS, which receiving service from the BS.
