A method is provided for communication in a wireless telecommunication system. The method comprises designating, by a network element, a first set of time-frequency resources for transmitting a first set of downlink control channels for a plurality of UEs, wherein the first set of time-frequency resources is known to the plurality of UEs, and wherein the first set of time-frequency resources varies from a first time interval to a second time interval. The method further comprises mapping, by the network element, a first downlink control channel to the first set of time-frequency resources. The method further comprises transmitting, by the network element, the first downlink control channel together with a downlink data channel in a frequency-division multiplexing manner.
