Abstract:
1. A bandwidth request method for use in a communication system including a base station and a mobile station, wherein the base station communicates with the mobile station using multiple carriers, the method comprising: determining, by the mobile station, for communication connections for which a bandwidth request is to be sent, a quality of service (QoS) of each of the communication connections; and sending, by the mobile station, the bandwidth request based on the determination to the base station, wherein when it is determined by the mobile station that the communication connections have different QoS classes, the method further comprises: separating, by the mobile station, the communication connections into a plurality of groups of communication connections, each of the groups having a same QoS class; calculating, by the mobile station, a total bandwidth required for each of the groups of communication connections, to thereby generate a plurality of calculated bandwidths; sending, by the mobile station, the bandwidth request wherein a group connection identifier is used; and sending, by the mobile station, separate requests as the bandwidth request when a random access to one of the multiple carriers is achieved, each of the separate requests for one of the plurality of calculated bandwidths.
