Abstract
A method for transmitting an uplink signal by a user equipment in a wireless communication system, including receiving, by the user equipment, an enhanced physical downlink control channel (EPDCCH); receiving, by the user equipment, a physical downlink shared channel (PDSCH) based on the EPDCCH; and transmitting acknowledgement/negative acknowledgement (ACK/NACK) information corresponding to the PDSCH using a PUCCH resource, wherein the PUCCH resource is determined based on an index of an enhanced control channel element (eCCE) for an EPDCCH and an index of an antenna port used for EPDCCH transmission.
Claims14
A method for transmitting an uplink signal by a user equipment in a wireless communication system, comprising:
- receiving, by the user equipment, an enhanced physical downlink control channel (EPDCCH);
- receiving, by the user equipment, a physical downlink shared channel (PDSCH) based on the EPDCCH;
- and
- transmitting acknowledgement/negative acknowledgement (ACK/NACK) information corresponding to the PDSCH using a PUCCH resource,
- wherein the PUCCH resource is determined based on an index of an enhanced control channel element (eCCE) for an EPDCCH and an index of an antenna port used for EPDCCH transmission.
A user equipment for transmitting an uplink signal in a wireless communication system, comprising:
- a radio frequency (RF) unit;
- and
- a processor configured to control the RF unit,
- wherein the processor controls the RF unit to receive an enhanced physical downlink control channel (EPDCCH), controls the RF unit to receive a physical downlink shared channel (PDSCH) based on the EPDCCH and controls the RF unit to transmit acknowledgement/negative acknowledgement (ACK/NACK) information corresponding to the PDSCH using a physical uplink control channel (PUCCH) resource,
- wherein the PUCCH resource is determined based on an index of an enhanced control channel element (eCCE) for an EPDCCH and an index of an antenna port used for EPDCCH transmission.
