Enhanced common downlink control channels
First Claim
1. A method for communication in a wireless telecommunication system, the method comprising:
- mapping, by a network element, an enhanced physical hybrid automatic repeat request (HARQ) indicator channel (E-PHICH) to a plurality of resource elements comprising HARQ acknowledgement/negative acknowledgement (ACK/NACK) response signals transmitted to user equipment (UEs), wherein resource blocks containing the E-PHICH are frequency-division multiplexed with resource blocks of a downlink data channel, and wherein a configuration of the plurality of resource elements for receiving the HARQ ACK/NACK response signals is signaled to the UEs before the HARQ ACK/NACK response signals are transmitted; and
transmitting the HARQ ACK/NACK response signals to the UEs via the E-PHICH,wherein at least one of the resource elements for transmitting one of the HARQ ACK/NACK response signals is located adjacent to at least one resource element used for a demodulation reference signal (DMRS), and at least another of the resource elements containing an enhanced physical control format indicator channel (E-PCFICH) is located adjacent to at least another resource element used for another DMRS.

Abstract
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.
