Abstract

Methods and apparatuses are disclosed regarding a field unit, which may receive a plurality of forward link assignment messages for a plurality of time slots for a plurality of forward link transmissions, each message including an indication of a modulation and a code rate associated with a respective forward link transmission. The unit may receive at least one of the forward link transmissions in at least two of the time slots at the respective indicated modulation and code rate. The unit may receive a plurality of reverse link assignment messages for a plurality of time slots for a plurality of reverse link transmissions, each message including an indication of a modulation and a code rate associated with a respective reverse link transmission. The unit may transmit at least one of the reverse link transmissions in at least two of the time slots at the respective indicated modulation and code rate.

Claims
