First Claim
Patent Images
1. A system comprising:
- a base station to generate at least one spatial stream in each sector of a plurality of sectors with subscriber stations, the base station comprising at least two antennas, the base station further comprising;
a V generator to generate a pre-defined pre-coding matrix, V, comprising a predetermined number of columns, each column corresponding to one of the plurality of spatial streams through which data is transmitted from the base station to the subscriber stations;
a feedback channel to receive a combined channel quality indicator, the combined channel quality indicator comprising an estimate of combined channel quality received by at least one of the subscriber stations;
a uniform scheduler to schedule data packets with a common scheduling priority in at least two of the plurality of sectors;
a plurality of resource blocks comprising the plurality of spatial streams, wherein the uniform scheduler schedules data for the at least one of the subscriber stations to each resource block based on the combined channel quality indicator.

7. A method comprising:
-
identifying a home sector of a base station using a subscriber station, wherein the base station is configured to transmit spatial streams to a home sector and at least one other sector; measuring channel quality indicator information using the subscriber station, from the home sector and the at least one other sector; implementing a sector micro diversity mechanism to form a combined channel quality indicator if a home sector channel quality indicator is less than a given threshold; transmitting the combined channel quality indicator from the subscriber station to the base station, the base station comprising a plurality of antennas; and receiving a plurality of resource blocks from the base station, wherein the subscriber station is configured to receive the plurality of resource blocks from the spatial streams transmitted by the base station. - View Dependent Claims (8, 9, 10, 11, 12)
