A method of a serving radio base station, RBS, in a communication system, for link adaptation, LA, of a physical downlink control channel, PDCCH, the method comprising: obtaining information about a reduced power subframe, RPS, pattern used by a first neighbouring RBS, and obtaining information about an RPS pattern used by a second neighbouring RBS; obtaining an indication of a reception quality of the PDCCH at a first user equipment, UE,; determining whether the obtained indication relates to the reception quality in a subframe in which the first neighbouring RBS is not using reduced power in accordance with the obtained RPS information, or to the reception quality in a subframe in which the first neighbouring RBS is using reduced power in accordance with the obtained RPS information, and determining whether the obtained indication of a reception quality relates to the reception quality in a subframe in which the second neighbouring RBS is not using reduced power in accordance with the obtained RPS information, or to the reception quality in a subframe in which the second neighbouring RBS is using reduced power in accordance with the obtained RPS information; controlling a first LA algorithm of a first LA loop for a first PDCCH to the first UE said first LA loop relating to subframes in which neither the first neighbouring RBS nor the second neighbouring RBS is using reduced power in accordance with the obtained RPS information; and controlling a second LA algorithm of a second LA loop for the first PDCCH to the first UE, said second LA loop relating to subframes in which both the first neighbouring RBS and the second neighbouring RBS are using reduced power in accordance with the obtained RPS information; controlling a third LA algorithm of a third LA loop for the first PDCCH to the first UE, said third LA loop relating to subframes in which the first neighbouring RBS is not using reduced power and in which the second neighbouring RBS is using reduced power in accordance with the obtained RPS information; and controlling a fourth LA algorithm of a fourth LA loop for the first PDCCH to the first UE, said fourth LA loop relating to subframes in which the first neighbouring RBS is using reduced power and in which the second neighbouring RBS is not using reduced power in accordance with the obtained RPS information; wherein at least one of the first, second, third and fourth LA algorithms, depending on said determining, is controlled based on said obtained indication of a reception quality. obtaining information about a reduced power subframe, RPS, pattern used by a first neighbouring RBS, and obtaining information about an RPS pattern used by a second neighbouring RBS; obtaining an indication of a reception quality of the PDCCH at a first user equipment, UE,; determining whether the obtained indication relates to the reception quality in a subframe in which the first neighbouring RBS is not using reduced power in accordance with the obtained RPS information, or to the reception quality in a subframe in which the first neighbouring RBS is using reduced power in accordance with the obtained RPS information, and determining whether the obtained indication of a reception quality relates to the reception quality in a subframe in which the second neighbouring RBS is not using reduced power in accordance with the obtained RPS information, or to the reception quality in a subframe in which the second neighbouring RBS is using reduced power in accordance with the obtained RPS information; controlling a first LA algorithm of a first LA loop for a first PDCCH to the first UE said first LA loop relating to subframes in which neither the first neighbouring RBS nor the second neighbouring RBS is using reduced power in accordance with the obtained RPS information; and controlling a second LA algorithm of a second LA loop for the first PDCCH to the first UE, said second LA loop relating to subframes in which both the first neighbouring RBS and the second neighbouring RBS are using reduced power in accordance with the obtained RPS information; controlling a third LA algorithm of a third LA loop for the first PDCCH to the first UE, said third LA loop relating to subframes in which the first neighbouring RBS is not using reduced power and in which the second neighbouring RBS is using reduced power in accordance with the obtained RPS information; and controlling a fourth LA algorithm of a fourth LA loop for the first PDCCH to the first UE, said fourth LA loop relating to subframes in which the first neighbouring RBS is using reduced power and in which the second neighbouring RBS is not using reduced power in accordance with the obtained RPS information; wherein at least one of the first, second, third and fourth LA algorithms, depending on said determining, is controlled based on said obtained indication of a reception quality.
