Method for transmitting uplink control information and user equipment, and method for receiving uplink control information and base station

摘要

Disclosed are a method and a UE for transmitting uplink control information, and a method and a BS for receiving uplink control information. According to the present invention, a time-frequency resource for the UL transmission, which collides with the DL transmission by the neighbor cell, can be removed or reduced to mitigate inter-cell interference.

主权项

1. A method for transmitting uplink control information at a user equipment (UE) to a base station (BS) in a time resource unit including a plurality of orthogonal frequency division multiplexing (OFDM) symbols in a time division duplex (TDD) system, the method comprising:
configuring an uplink control channel in the time resource unit; and transmitting the uplink control information in the time resource unit to the BS through the uplink control channel, wherein when the time resource unit includes an interfering OFDM symbol in which interference caused by a downlink control channel occurs, the uplink control channel is configured in a specific format from among a plurality of uplink control channel formats.
