Abstract: Disclosed are methods for transmission and reception of a paging channel between user equipment (UE) and a base station in a wireless communication system. In particular, the present invention may comprise the steps of: receiving, in a paging occasion of UE, a control channel for a paging channel; attempting to receive the paging channel on the basis of downlink control information (DCI) including information indicating a retransmission time of the paging channel; and if reception of the paging channel fails, reattempting to receive the paging channel at the retransmission time indicated by the DCI.

Abstract: The present disclosure relates to a method and device for receiving a paging signal in a radio resource control (RRC) connected mode. More specifically, the present disclosure relates to a method and a device therefor, the method comprising the steps of: receiving gap configuration information indicating a gap section in a search space; when a first search space related to a data signal in a specific time interval and a second search space related to the paging signal are configured in different narrowbands (NBs), monitoring the second search space in the specific time interval, wherein the first search space is not monitored in the specific time interval on the basis of the gap section; and when the first search space and the second search space are configured in one NB in the specific time interval, monitoring the first search space and the second search space in the specific time interval without applying the gap section.

Abstract: The present disclosure suggests a method for adjusting the size of a contention window of a base station/terminal. The method comprises transmitting a physical downlink shared channel (PDSCH) to a user equipment (UE) through a frequency bandwidth, receiving an acknowledgement/negative-acknowledgement (ACK/NACK) signal for the PDSCH from the UE, and adjusting the contention window based on the ACK/NACK signal, wherein based on the frequency bandwidth overlapping with a plurality of frequency bands, the BS adjusts the contention window for each of the plurality of frequency bands based on the ACK/NACK signal.
