Abstract: Embodiments of the present invention relate to a wireless access system supporting a non-licensed band and, more particularly, to methods for transmitting or receiving sub-frame length information indicating the lengths of current and next sub-frames, and apparatuses for supporting the same. As an embodiment of the present invention, a method for receiving sub-frame (SF) length information in a wireless access system supporting a non-licensed band may comprise the steps of: receiving a signal including first SF length information indicating the lengths of one or more of a current SF and a next SF in sub-frame number n−1 (SF # n−1); and receiving one or more of a downlink physical channel and a downlink signal in the SF # n−1 on the basis of the first SF length information. Here, the first SF length information may indicate that the current SF or the next SF is the end SF of a downlink transmission burst in the non-licensed band.

Abstract: The disclosure of the present invention proposes a method for connecting to a base station. The method may be performed by a user equipment (UE) and comprise: receiving information on a UE-specific bandwidth of a first cell. Here, the UE-specific bandwidth of the first cell is variable based on a bandwidth of a second cell using long term evaluation (LTE) radio access technology (RAT). The information on the UE-specific bandwidth may indicate a bandwidth between a bandwidth between a minimum bandwidth and a maximum bandwidth.

Abstract: Disclosed are methods for transmission and reception of downlink control information between a base station and a terminal, and devices for supporting same. Disclosed more particularly are: methods whereby a base station transmits downlink control information by means of an analogue beam independently determined for every one or more symbols (e.g., a unit of one or more symbols) and, in response to the base station, a terminal receives, by means of a serving beam of the terminal, the downlink control information transmitted by means of the analogue beam, which corresponds to the serving beam; and devices for supporting same.

Abstract: A method of monitoring a control signal in a wireless communication system, where the method is performed by a user equipment (UE) and includes: selecting at least one control resource set (CORESET) among a plurality of CORESETs based on an overlap between physical downlink control channel (PDCCH) monitoring occasions in the plurality of CORESETs; and monitoring a PDCCH only in the selected at least one CORESET, among the plurality of CORESETs. The method also includes: based on the at least one CORESET including a first CORESET, and based on a first reference signal of the first CORESET and a second reference signal of a second CORESET being associated with a same synchronization signal/physical broadcast channel block (SSB): monitoring the PDCCH in both the first CORESET and the second CORESET.

Abstract: According to one embodiment of the present invention, a method of receiving DCI by a UE includes receiving bundling information regarding REGs via higher layer signaling, performing blind detection for a PDCCH in a CORESET configured on a plurality of OFDM symbols, and acquiring DCI from the PDCCH. When the bundling information indicates a first value, the UE may perform bundling such that only REGs locating on a same RB and corresponding to different OFDM symbols in the CORESET, are bundled as 1 REG bundle, and when the bundling information indicates a second value, the UE may perform bundling such that the REGs locating on the same RB and corresponding to the different OFDM symbols are bundled as 1 REG bundle along with REGs locating on different RBs in the CORESET, and the UE may perform the blind detection of the PDCCH by assuming same precoding for REGs belonging to a same REG bundle as a result of REG bundling.
