Claim:
1. A method for operating a user equipment device, the method comprising: receiving first control information from a first base station within a first coverage area, wherein the first control information occurs within a first time interval and first frequency subset, wherein a second base station is configured to transmit second control information in the first time interval and the first frequency subset within a second coverage area, wherein the first and second coverage areas are substantially different; receiving third control information from a third base station, wherein the third control information occurs within the first time interval and a second frequency subset within a third coverage area, wherein a fourth base station is configured to transmit fourth control information in the first time interval and the second frequency subset within a fourth coverage area, wherein each of the third and fourth coverage areas overlaps the first coverage area in one or more parts of the first coverage area, wherein the third and fourth base stations do not interfere with the first base station in the one or more parts of the first coverage area; receiving first payload data from the first base station based on the first control information; and receiving second payload data from the third base station based on the third control information; wherein a first set of base stations of a first type, comprising the first and second base stations, operate within the first frequency subset and not within the second frequency subset; and wherein a second set of base stations of a second type, corresponding to low power base stations and comprising the third and fourth base stations, operate within the second frequency subset and not the within the first frequency subset.
