    摘要： Disclosed is a method for requesting allocation of uplink bandwidth for uplink data transmission and allocating the uplink bandwidth in a wireless communication system. In the method, when a number of uplink bandwidth allocation requests having occurred in a certain interval is different from that of scheduled uplink bandwidth allocation requests, uplink bandwidths are allocated to the extent that the occurred uplink bandwidth allocation requests can be implanted. Herein, the uplink bandwidth allocation requests occur in an MS according to services. Accordingly, as the uplink bandwidth allocation requests increase, uplink bandwidths also increase. However, as the uplink bandwidth allocation requests decrease, uplink bandwidths also decrease.

    摘要： Disclosed is a method and system for synchronizing base stations in a communication system. A mobile station receives reference base station information and base station group information, selects a synchronization correction-requiring base station from among a plurality of base stations included in a base station group corresponding to the base station group information, detects a timing offset based on reference signals received from the reference base station and synchronization correction-requiring base station, and transmits the timing offset to the synchronization correction-requiring base station so as to enable the synchronization correction-requiring base station to correct synchronization, thereby synchronizing the base stations in consideration of a real channel environment.
