Claim:
1. A method of managing peak-to-average power ratio (PAPR) for multi-carrier modulation in a wireless multi-carrier communication system, comprising: determining a maximum number of carriers that may be allocated for data transmission between an access point and at least one terminal in a plurality of terminals based on a determined required transmit power for the at least one terminal, the determined required transmit power being based on path loss or received signal quality or both associated with the at least one terminal relative to the access point; computing a difference between a maximum transmit power for the at least one terminal and the determined required transmit power for the at least one terminal corresponding to the path loss or the received signal quality associated with the at least one terminal, wherein determining the maximum number of carriers that may be allocated to the at least one terminal is based on the computed difference; and allocating for the data transmission between the access point and the at least one terminal, a specific number of carriers based at least on the maximum number of carriers determined for the data transmission between the access point and the at least one terminal, wherein multiple carriers are allocated for the data transmission between the access point and the at least one terminal, and wherein the specific number is larger than another number of carriers allocated for data transmission to or from another terminal having higher transmit power that operates at a smaller back-off relative to said at least one terminal.
