20110019768 | METHOD AND APPARATUS FOR SPECTRALLY EFFICIENT LINK ADAPTATION USING HARQ IN OFDMA SYSTEMS - A method increases spectral efficiency in a communication system. The communication system includes at least one mobile station and is capable of transmitting messages encoded according to a plurality of available modulation coding schemes (“MCSs”). Each available MCS includes a modulation scheme and an effective coding rate. The MCSs are indexed according to increasing complexity. A signal-to-interference ratio (“SINR”) is determined which is sufficient to satisfy a predetermined frame error rate (“FER”). A first MCS and a corresponding amount of transmissions needed to satisfy the predetermined FER at the SINR using the first MCS are determined. The first MCS has a higher effective coding rate than a second MCS. The second MCS sufficiently satisfies the predetermined FER at the SINR in a single transmission. A message encoded according to the first MCS is transmitted through the communication system using hybrid automatic repeat request (“HARQ”) | 01-27-2011 |
20110034206 | METHOD AND APPARATUS FOR CANDIDATE LIST GENERATION FOR UPLINK V-MIMO - A method selects mobile station candidates for use with virtual multiple-input multiple-output (“V-MIMO”) in a communication system. The communication system includes at least one base station and a plurality of mobile stations. At least one downlink metric is determined for a first mobile station. The at least one downlink metric is used to determine eligibility for uplink V-MIMO candidate list selection. Responsive to determining that the first mobile station is eligible for uplink V-MIMO candidate list selection, the first mobile station is paired with a second mobile station eligible for uplink V-MIMO candidate list selection. | 02-10-2011 |
