Abstract: Provided are a method for determining the number of hybrid automatic repeat request (HARQ) processes in a carrier aggregated system configured with a plurality of serving cells, and an apparatus using such a method. The method receives data from a downlink subframe of a second serving cell, and transmits an ACK/NACK signal for the data from an uplink subframe of a first serving cell, wherein the first serving cell uses a first-type frame, the second serving cell uses a second-type frame, and the number of HARQ processes in the second serving cell are determined with respect to each subframe comprised in the second-type frame and on the basis of the number of downlink subframes comprised in each section comprising a set number of subframes.

Abstract: The present disclosure relates to a wireless access system supporting an unlicensed band, and provides a method for configuring a transmission opportunity period (TxOP) and devices for supporting the same. The method for configuring a TxOP in a wireless access system supporting an unlicensed band, according to one embodiment of the present disclosure, can comprise the steps of: performing a carrier sensing step for checking whether a secondary cell (SCell) constituted in an unlicensed band is in an idle state; transmitting a reservation signal for a predetermined amount of time if the SCell is in the idle state; and configuring a TxOP in the SCell. At this time, a start point of a first subframe (SF) included in the TxOP can be matched to a subframe, a slot or symbol boundary of a primary cell (PCell) constituted in a licensed band.
