METHOD AND NETWORK NODE FOR LINK ADAPTATION IN A WIRELESS COMMUNICATIONS NETWORK

摘要

A method in network node for selecting a downlink modulation and coding scheme is provided. The network node obtains information comprising a first uplink signal strength of a transmission from the terminal in the first cell. The network node further obtains information comprising a second uplink signal strength of a transmission from the terminal in the second cell. The network node also obtains scheduled downlink transmission information for the respective first cell and second cell. The network node then selects a downlink modulation and coding scheme for transmission from one or more of the access point serving the first cell and the access point serving the second cell to the terminal. The selection is based on the obtained information comprising the first uplink signal strength, the obtained information comprising the second uplink signal strength, and the obtained scheduled downlink transmission information for the respective first cell and second cell.
