Title:
METHOD FOR TRANSMITTING UPLINK CONTROL INFORMATION AND USER EQUIPMENT, AND METHOD FOR RECEIVING UPLINK CONTROL INFORMATION AND BASE STATION
Document Type and Number:
WIPO Patent Application WO/2012/169753
Kind Code:
A3
Abstract:
The present invention provides a method and apparatus for uplink transmission / reception of at least one slot in a sub-frame comprising two slots. A base station transmits information which controls the slot performing the uplink transmission among the two slots, to user equipment, and the user equipment performs uplink transmission from the slot directed by the Information. When the user equipment transmits ACK / NACK information, the ACK / NACK information is transmitted from the first slot of the user equipment if the CCE associated with the first slot is the CCE included in the PDCCH of the user equipment, and the ACK / NACK information is transmitted from the second slot if the CCE is the CCE associated with the second slot.
