Patent ID: 8270426

Claim:
A method of performing communicating at a transmitting side in a wireless communication system, the method comprising: selecting one of a modulation and coding scheme (MCS) index according to a first scheme and a resource allocation scheme according to a second scheme; and using the selected one of the modulation and coding scheme (MCS) index and the resource allocation scheme to perform the communicating, wherein the resource allocation scheme comprises one of a localized resource allocation scheme that allocates data to subcarriers in a contiguous manner, and a distributed resource allocation scheme that allocates data to the subcarriers in a non-contiguous manner, wherein the first scheme includes: selecting a MCS index having a coding rate that is greater than or equal to a coding rate threshold if a resource allocation scheme of the transmitting side employs a localized resource allocation scheme; and selecting a MCS index having a coding rate that is less than the coding rate threshold if the resource allocation scheme of the transmitting side employs a distributed resource allocation scheme, and wherein the second scheme includes: selecting the localized resource allocation scheme as the resource allocation scheme by the transmitting side if a selected MCS index is the MCS index that has the coding rate that is greater than or equal to the coding rate threshold; and selecting the distributed resource allocation scheme as the resource allocation scheme by the transmitting side if the selected MCS index is the MCS index having the coding rate that is less than the coding rate threshold.
