Tile allocation method

A computer program product stored on a non-transitory computer readable medium wherein the product includes instructions of program code for implementing a method of allocating and transmitting groups of subcarriers, called tiles, between a plurality of transceiver antennas, when run on a computer, wherein the method comprises:

• a subscriber station transceiver receiving at least one downlink signal through at least one of the plurality of transceiver antennas;
• the subscriber station transceiver characterizing a received signal of at least one downlink signal over multiple subcarriers, by calculating at least one metric;
• and
• the subscriber station transceiver allocating tiles for uplink transmission through at least one of the plurality of transceiver antennas, wherein allocating tiles is based on the characterized received signal of the at least one downlink signal over multiple subcarriers and is based on a required power Ptx for uplink transmission compared with a maximum power P that each of the plurality of said transceiver antennas can emit.
