Patent ID: 8891367

Claim:
A method for allocating uplink resources using information of a Bandwidth Request (BR) indicator in a Base Station (BS), the method comprising: receiving a BR indicator including a station Identifier (ID), and a Quality of Service (QoS) parameter from a Mobile Station (MS); estimating uplink resources based on the BR indicator and allocating the estimated uplink resources to the MS, wherein if there are a plurality of connections for the MS, the estimating further comprises deciding one QoS parameter to be used to estimate the uplink resources among a plurality of QoS parameters corresponding to the connections; and transmitting information about the allocated uplink resources to the MS through an uplink grant message, wherein the BR indicator further includes a BR type field and a BR size field, the BR type field indicating a BR type 1 for increasing or decreasing an amount of the estimated uplink resources by an increment or a decrement indicated by the BR size field, and a BR type 2 for requesting allocation of a desired amount of the uplink resources, and wherein if the BR type field indicates the BR type 1, the BR indicator further includes a BR sign field, the BR sign field indicating whether an amount of the estimated uplink resources is needed to be increased by the increment or an amount of the estimated uplink resources is needed to be decreased by the decrement.
