Patent ID: 8718081

Claim:
A method of wireless communication power control comprising: allocating a first plurality of subcarriers into a first plurality of groups, subcarriers within each group of said first plurality of groups having a consistent subcarrier power level, said each group of said first plurality of groups having a different subcarrier power level from other groups of said first plurality of groups; allocating a second plurality of subcarriers into a second plurality of groups, subcarriers of each group of said second plurality of groups having a same subcarrier power level, said each group of said second plurality of groups having a different subcarrier power level, wherein a group with a highest subcarrier power level in said second plurality of groups uses different subcarriers than a group with a highest subcarrier power level in said first plurality of groups; receiving at a first communication device at a first transmit location and from a user device at a first receive location a determined suitable subcarrier power level, wherein said determined suitable subcarrier power level is based at least in part on a comparison of a signal power of a first signal received at said user device at said first receive location and transmitted from said first communication device at said first transmit location with a signal power of a second signal received at said user device at said first receive location and transmitted from a second communication device at a second transmit location; assigning one subcarrier of said first plurality of subcarriers to a wireless communication link, said one subcarrier belonging to a group of said first plurality of groups, said consistent subcarrier power level of said group of said first plurality of groups being suitable for said wireless communication link based on said determined suitable subcarrier power level, and said wireless communication link uses Orthogonal Frequency Division Multiple Access (OFDMA); receiving an updated suitable subcarrier power level; and assigning to said wireless communication link a new subcarrier from a different group of said first plurality of groups based on said updated suitable subcarrier power level.
