Method and devices for selecting transmission resource in wireless access system supporting non-licensed band
First Claim
1. A method of selecting an uplink transmission resource, which is selected by a user equipment (UE) in a wireless access system supporting an unlicensed band, the method comprising:
- receiving, from an evolved NodeB (eNB), first information related to a resource selection area and second information on a reservation resource configuration for the unlicensed band;
selecting an uplink transmission resource among resources of the unlicensed band in a time interval, based on the resource selection area; and
transmitting a signal via the selected uplink transmission resource,wherein the time interval for the resource selection area is determined based on a reservation resource period (RRP),wherein the RRP is determined based on the reservation resource configuration, and used for an eNB-scheduling based signal transmission, andwherein the uplink transmission resource is selected from the resource selection area without receiving an uplink grant from the eNB.

Abstract
The present invention relates to a wireless access system supporting a non-licensed band and provides a method for selecting an uplink transmission resource and devices for same. A method for selecting the uplink transmission resource in the wireless access system, according to one embodiment of the present invention, may comprise the steps of: receiving, from an eNB, information related to a resource selection area; selecting an uplink transmission resource in a cell in which the non-licensed band is formed for the resource selection area according to the information related to the resource selection area; and transmitting a signal through the selected uplink transmission resource, wherein the uplink transmission resource in the resource selection area may be selected without receiving an uplink grant from the eNB.

11. A User Equipment (UE) selecting an uplink transmission resource in a wireless access system supporting an unlicensed band, the UE comprising:
-
a transmitter; a receiver; and a processor coupled to the transmitter and the receiver, the processor configured to; control the receiver to receive, from an evolved NodeB (eNB), first information related to a resource section area and second information on a reservation resource configuration for the unlicensed band; select an uplink transmission resource among resources of the unlicensed band in a time interval, based on the resource selection area; and control the transmitter to transmit a signal via the selected uplink transmission resource, wherein the time interval for the resource selection area is determined based on a reservation resource period (RRP), wherein the RRP is determined based on the reservation resource configuration, and used for an eNB-scheduling based signal transmission, and wherein the uplink transmission resource is selected from the resource selection area without receiving an uplink grant from the eNB.
