Abstract:
1. For use in a wireless network, a base station for transmitting in a downlink to a plurality of subscriber stations using a plurality of antennas according to a multiple input, multiple-output (MIMO) protocol, wherein, during a first downlink subframe, the base station is configured to operate in single-user MIMO mode in which the base station transmits a first data subpacket to a first subscriber station using a first antenna and transmits a second data subpacket to the first subscriber station using a second antenna, wherein, during a second downlink subframe following the first downlink subframe, the base station is configured to operate in multi-user MIMO mode in which the base station transmits a third data subpacket to the first subscriber station using the first antenna and transmits a fourth data subpacket to a second subscriber station using the second antenna, the first, second, third, and fourth data subpackets generated from original data packets using at least one error correction technique, wherein the base station is configured to alternate between operating in single-user MIMO mode and operating in multi-user MIMO mode repeatedly within a single frame.
