Method and device for transmitting and receiving downlink control channel for controlling inter-cell interference in wireless communication system

摘要

The present invention relates to a wireless communication system, and more particularly, to a method and device for transmitting and receiving a downlink control channel for controlling inter-cell interference in a wireless communication system. An embodiment of the present invention provides a method for transmitting a downlink control channel from a base station to a terminal, and the method may comprise: a step of determining whether a downlink subframe is of a first type or a second type; and a step in which if the downlink subframe is of the first type, the number of OFDM symbols for transmitting the downlink control channel is set to a preset value (N), and the downlink control channel is transmitted using N OFDM symbols.

1. A method of a base station transmitting a downlink control channel to a user equipment, the method comprising:
determining a type of a downlink subframe; setting a number of OFDM (orthogonal frequency division multiplexing) symbols used for the downlink control channel to a predefined value and transmitting the downlink control channel via the OFDM symbols when the downlink subframe corresponds to a first type subframe; and transmitting information about a number of OFDM symbols used for the downlink control channel via a PCFICH (physical control format indicator channel) and transmitting the downlink control channel via the OFDM symbols when the downlink subframe corresponds to a second type subframe.
