Enhanced PHICH transmission for LTE-advanced
First Claim
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.

Abstract
A method is provided for communication in a wireless telecommunication system. The method comprises generating a sequence of signals of an enhanced physical HARQ (hybrid automatic repeat request) indicator channel (E-PHICH). The method further comprises mapping 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).

15. A network element comprising:
-
a processor configured such that the network element; generates a sequence of signals of an enhanced physical HARQ (hybrid automatic repeat request) indicator channel (E-PHICH); maps 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 transmits 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. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28)

29. A user equipment (UE) comprising:
-
a processor configured such that the UE receives a sequence of signals of an enhanced physical HARQ (hybrid automatic repeat request) indicator channel (E-PHICH), wherein the sequence of signals has been mapped to a first set of resource elements, and wherein the first set of resource elements has been 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), the processor further configured such that the UE receives 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. - View Dependent Claims (30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43)
