MCS TABLE ADAPTATION FOR 256-QAM

摘要

The present invention relates to adaptive modulation and coding scheme selection and signaling in a communication system. In particular, a modulation and coding scheme to be used for transmission of a data is selected from a set of predetermined modulation and coding schemes. The predetermination of the set is performed by selecting the set from a plurality of predefined sets. The sets have the same size, so that a modulation and coding selection indicator signaled to select the modulation and coding scheme may be advantageously applied to any of the selected sets. Moreover, a second set includes schemes with a modulation not covered by the schemes of a first set, and which is of a higher order than any modulation in the first set.

主权项

1. An apparatus for receiving data from a network node in a communications system, the apparatus comprising:
a control information reception unit for receiving scheduling information specifying resources on which data are to be transmitted and including a modulation and coding indicator; a modulation and coding selection unit capable of selecting modulation and coding from a set of predefined modulation and coding schemes according to the modulation and coding indicator, a set selection unit for selecting the set of predefined modulation and coding schemes from at least two predefined sets—the first set and the second set, which have a plurality of modulation and coding schemes in common and differ in that the second set further includes an additional modulation with an order higher than any modulation in the first set, and the first set and the second set have the same size; and a data transmission unit for transmitting the data on the scheduled resources using the selected modulation and coding.
