  • Method and base station for link adaptation of PDCCH in a radio communication system
    Patent number: 9668222
    Abstract: The present disclosure relates to a method and a serving radio base station (RBS) for link adaptation (LA) of PDCCH. The method includes obtaining information about a reduced power subframe (RPS) pattern used by a neighboring RBS. An indication of a reception quality of the PDCCH at a user equipment (UE) is obtained. A determination is made whether the obtained indication relates to an RPS or a non-RPS according to the obtained information. A first LA loop for a PDCCH to the first UE is controlled. The first LA loop relates to non-RPS. A second LA loop for the PDCCH to the UE is controlled. The second LA loop relates to RPS. At least one of the first and second LA algorithms, depending on the determining, is controlled based on the obtained indication of a reception quality.
