Patent ID: 8385364

Claim:
A method to allocate resources in a single-cell discrete Fourier transform spread orthogonal frequency division multiple access (DFT-S-OFDMA) network, comprising: for each user, determining a reward for assigning each permissible frequency chunk (FC), where each FC is a set of contiguous subcarriers; splitting each user into one or more sub-users, each sub-user having identical rewards; and assigning resources using a greedy heuristic or a message-passing based procedure; wherein the reward for a k th user, is determined when assigning a chunk of subcarriers or resource blocks (RBs) starting from the i th subcarrier or RB [i , . . . , i+n−1] of size n as w k c ki n , where c k,i n is the maximum achievable rate under the available modulation and coding schemes (MCS) and power budget and w k is the weight or priority of user k.
