摘要： 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")

摘要： Upon receiving a particular data unit by a receiving layer of a wireless device, it is detected that a previous data unit earlier in sequence to the particular data unit has not yet been received by the receiving layer. A timer is started in response to the detecting, where the timer has a timeout period that is variable dependent upon a parameter associated with receipt of the particular data unit. Upon expiration of the timer based on the timeout period, the receiving layer generates an error indication.
