Enhanced common downlink control channels

摘要

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.

1. A method for communication in a wireless telecommunication system, the method comprising:
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 user equipment (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, wherein the first set of time-frequency resources comprise at least one of consecutive or distributed resources designated for an enhanced physical downlink control channel (E-PDCCH); mapping, by the network element, a first region of the E-PDCCH to the first set of time-frequency resources; and transmitting, by the network element, the E-PDCCH in a subframe comprising a physical downlink control channel (PDCCH) and a physical downlink shared channel (PDSCH), wherein the E-PDCCH is transmitted simultaneously with the PDSCH in a frequency-division multiplexing manner such that the E-PDCCH occupies different resource blocks (RBs) than the PDSCH, wherein resource allocation configuration of the first set of time-frequency resources is dynamically signaled through an enhanced physical control format indicator channel (E-PCFICH) that is transmitted earlier in time than the E-PDCCH.
