Abstract:
1. A method for wireless communication, comprising the steps of determining sectors of a cell; determining a first downlink transmission beam and a second downlink transmission beam in said sectors based on a received user-derived signal, the first downlink transmission beam being substantially uncorrelated with the second downlink transmission beam, the first downlink transmission beam being associated with a portion within a first sector of said spatial domain, the second downlink transmission beam being associated with a portion within a second sector; diversity encoding a first signal in said first sector to produce a first diversity-encoded signal; diversity encoding a second signal in said second sector to produce a second diversity-encoded signal; sending the first diversity-encoded signal over the first downlink transmission beam; and sending the second diversity-encoded signal over the second downlink transmission beam; wherein the first downlink transmission beam is associated with a first uplink multipath from a plurality of uplink multipaths associated with a first user, the second downlink transmission beam is associated with a second uplink multipath from the plurality of uplink multipaths, the first uplink multipath and the second uplink multipath being no less optimal than the remaining uplink multipaths from the plurality of uplink multipaths.
