US 10,477,531 B2 · Method and device for setting a control channel and a data channel in a wireless communication system

Abstract

The present invention relates to a method for configuring a starting position of a control channel in a wireless communication system, and a terminal using the same. The method includes receiving duration information about a physical downlink control channel from the first orthogonal frequency division multiplexing (OFDM) symbol of a downlink subframe; and configuring a first OFDM symbol after OFDM symbols indicated by the duration information, as a starting point of an enhanced-physical downlink control channel. The downlink subframe includes a plurality of subcarriers in a frequency domain and 12 or 14 OFDM symbols in a time domain. The PDCCH includes the first N (N is a natural number of from 1 to 4) number of OFDM symbols of the downlink subframe. The duration information indicates the N number of OFDM symbols. The E-PDCCH comprises the starting point to the last OFDM symbol of the downlink subframe.

Dependent claims

A method for receiving a data channel in a carrier aggregation system, the method performed by a user equipment (UE) which is configured with a plurality of serving cells and comprising:

receiving position information informing of a starting orthogonal frequency division multiplexing (OFDM) symbol for an Enhanced Physical Downlink Control CHannel (EPDCCH) through a Radio Resource Control (RRC) message;
receiving the EPDCCH;
and
receiving a physical downlink shared channel (PDSCH) assigned by the EPDCCH,
wherein, if the EPDCCH and the PDSCH are received in a same serving cell, a starting OFDM symbol for the PDSCH is given by the position information.
