Claim:
1. A method of operation of a user equipment in a cellular network, the method comprising: receiving, by the user equipment, a downlink subframe, the downlink subframe comprising a plurality of downlink control channels; determining a division of the downlink control channels into at least one common subset of the downlink control channels and a plurality of group subsets of the downlink control channels, the determination being based, at least in part, on an assignment of resources received by the user equipment in a control region of the downlink subframe, the at least one common subset being a subset of downlink control channels which is mandatory for all user equipments in the cellular network to decode, and the plurality of group subsets being a plurality of subsets of downlink control channels in which decoding of any particular group subset among the plurality of group subsets is mandatory for a limited group of user equipments in the cellular network; determining a group subset from the plurality of group subsets to decode, the determined group subset being a relevant group subset; and decoding the downlink control channels forming the common subset or each common subset of the downlink control channels, and decoding only the downlink control channels of the relevant group subset of the downlink control channels.
