Patent ID: 8483158

Claim:
A method for allocating uplink (UL) resource in a network terminal of a wireless communication system, the method comprising: informing a user equipment (UE) about resource allocation via a resource allocation field in a UL grant message, to indicate the UE to use M clusters out of N radio units to perform uplink transmission; wherein each of the M clusters comprises at least one contiguous radio units, the UL grant message indicates a starting location and an ending location of each of the M clusters, the UL grant message uses a value (r) to indicate the starting location and the ending location of each of the M clusters, and the value (r) is a sum of binominal coefficients where r = ∑ i = 0 2 ⁢ M - 1 ⁢ 〈 N - s i 2 ⁢ M - i 〉 ⁢ ⁢ in ⁢ ⁢ which ⁢ ⁢ { s i } i = 0 2 ⁢ M - 1 indicates the starting location and the ending location of each cluster, and 〈 x y 〉 = { ( x y ) x ≥ y 0 x < y .
