Abstract
Official abstract text for this publication.
The present invention provides a method for receiving acknowledgement/not-acknowledgement (ACK/NACK) of a terminal in a wireless communication system. The method transmits uplink data through an uplink data channel and receives ACK/NACK for the uplink data. The uplink data channel is transmitted through aggregated carriers and the aggregated carriers include a first band recognizable to first and second type terminals and a second band recognizable only to the second type terminal.
First claim
Opening claim text (preview).
1 .- 10 . (canceled) 11 . A method of communication by a user equipment (UE) in a wireless communication system, the method comprising: receiving physical hybrid-ARQ indicator channel (PHICH) information indicating PHICH duration; and receiving information indicating a starting symbol of an enhanced-physical downlink control channel (E-PDCCH) via a radio resource control (RRC) message, wherein the starting symbol of the E-PDCCH is configured after the PHICH duration. 12 . The method of claim 11 , wherein the physical hybrid-ARQ indicator channel (PHICH) information indicating PHICH duration is received via another RRC message. 13 . The method of claim 11 , wherein the starting symbol is an orthogonal frequency division multiplexing (OFDM) symbol. 14 . The method of claim 11 , wherein the PHICH duration is one of normal PHICH duration and extended PHICH duration. 15 . The method of claim 14 , wherein if the PHICH duration is the normal PHICH duration and a subframe configured at the UE is a non-Multicast-broadcast single-frequency network (MBSFN) subframe, the value of the PHICH duration is 1. 16 . The method of claim 14 , wherein if the PHICH duration is normal PHICH and a subframe configured at the UE is a Multicast-broadcast single-frequency network (MBSFN) subframe on a carrier supporting a Physical Downlink Shared Channel (PDSCH), the value of the PHICH duration is 1. 17 . A user equipment (UE), the UE comprising: a radio frequency (RF) unit that transmits and receives a radio signal; and a processor operatively coupled to the RF unit, wherein the processor: receives physical hybrid-ARQ indicator channel (PHICH) information indicating PHICH duration; and receives information indicating a starting symbol of an enhanced-physical downlink control channel (E-PDCCH) via a radio resource control (RRC) message, wherein the starting symbol of the E-PDCCH is configured after the PHICH duration.
