METHOD AND DEVICE FOR TRANSMITTING AND RECEIVING DATA IN WIRELESS ACCESS SYSTEM SUPPORTING UNLICENSED BAND

摘要

The present invention provides one of embodiments comprising: receiving an upper layer signal including configuration information which indicates the size and use of the TxOP period in a primary cell (Pcell); receiving a scheduling grant including scheduling information on the TxOP period in a first subframe of the TxOP period; and transmitting and receiving data according to the use of the TxOP period on the basis of the scheduling information in a secondary cell (Scell) during the TxOP period, wherein the size of the TxOP period is defined by the number of subframes of the Scell and the use of the TxOP period is set by a downlink data transmission or an uplink data transmission, wherein whether the subframes of the Scell are included in the TxOP period can be determined according to a transmission direction of subframes of the Pcell corresponding to the subframe of the Scell.

主权项

1. A method for transmitting and receiving data during a transmission opportunity (TxOP) period in a wireless access system supporting carrier aggregation (CA) with an unlicensed band, the method performed by a user equipment (UE) and comprising:
receiving a higher layer signal on a primary cell (Pcell), the higher layer signal including configuration information which indicates a size and a use of the TxOP period; receiving a scheduling grant including scheduling information on the TxOP period at a first subframe of the TxOP period; and transmitting and receiving data in accordance with the use of the TxOP period on the basis of the scheduling information in a secondary cell (Scell) during the TxOP period, wherein the size of the TxOP period is defined by a number of subframes of the Scell and the use of the TxOP period is set for downlink data transmission or uplink data transmission, wherein whether the subframes of the Scell are included in the TxOP period is determined in accordance with a transmission direction of subframes of the Pcell corresponding to the subframes of the Scell.
