METHOD FOR CONFIGURING TRANSMISSION OPPORTUNITY SECTION IN WIRELESS ACCESS SYSTEM SUPPORTING UNLICENSED BAND, AND DEVICE FOR SUPPORTING SAME

摘要

The present invention relates to a wireless access system supporting an unlicensed band, and provides a method for configuring a transmission opportunity (TxOP) section, and devices for supporting the same. The method for configuring a transmission opportunity (TxOP) section in a wireless access system supporting carrier aggregation (CA) with an unlicensed band, in one embodiment of the present invention, comprises the steps of: receiving, by a terminal, TxOP start information for indicating the start of the TxOP section; receiving orthogonal frequency division multiplexing (OFDM) symbol position information for indicating an OFDM symbol starting data transmission and reception in the TxOP section; and transmitting and receiving the data in a subframe (SF) of an S cell indicated by the TxOP start information on the basis of the OFDM symbol position information.

1. A method of configuring a transmission opportunity (TxOP) duration in a wireless access system supporting carrier aggregation (CA) with an unlicensed band, the method performed by a user equipment (UE) and comprising:
receiving TxOP start information for indicating a start of the TxOP duration; receiving OFDM symbol position information for indicating an orthogonal frequency division multiplexing (OFDM) symbol at which data transmission and reception start in the TxOP duration; and transmitting and receiving data based on the OFDM symbol position information in a subframe (SF) of a Scell indicated by the TxOP start information.
