Method for performing an adaptive modulation and coding scheme in mobile communication system

摘要

A method for performing an adaptive modulation and coding scheme in a mobile communication system. Including receiving a signal and selecting a modulation and coding scheme (MCS) level from an MCS subset of an MCS set considering information derived from the signal, by a mobile station. The MCS subset is selected in accordance with a service type related to the mobile station and the MCS subset is configured with one or more MCS levels, the MCS set is represented by 5 bits and the MCS subset is represented by 4 bits to indicate MCS value, respectively, and the 4 bits of the MCS subset is a part of the 5 bits of the MCS set.

1. A method for performing an adaptive modulation and coding (AMC) scheme in a mobile communication system, the method performed by a receiver and comprising:
receiving MCS information from a transmitter, wherein a size of the MCS information is 5 bits; identifying a modulation and coding scheme (MCS) level from an MCS set according to the MCS information; and communicating with the transmitter using the MCS level, wherein the MCS set includes a MCS subset defined in accordance with a service type of the receiver, wherein the MCS subset is configured with one or more MCS levels having different modulation schemes, and wherein the MCS level is indicated by using four bits of the MCS information when the MCS level is selected from the MCS subset.
