1. A method for communication in a wireless telecommunication system, the method comprising:

  • generating, by a network element, a sequence of signals of an enhanced physical HARQ (hybrid automatic repeat request) indicator channel (E-PHICH);

    mapping, by the network element, the sequence of signals of the E-PHICH to a first set of resource elements, wherein the first set of resource elements is multiplexed with a second set of resource elements over a set of virtual resource blocks, and wherein the second set of resource elements carries at least one of an enhanced physical downlink control channel (E-PDCCH) and a physical downlink shared channel (PDSCH); and

    transmitting the sequence of E-PHICH signals in separate virtual resource blocks than the E-PDCCH, wherein the separate virtual resource blocks are mapped to physical resource blocks such that each physical resource block carrying E-PHICH signals is different than each physical resource block carrying E-PDCCH.
