Abstract: The present invention discloses a method for a user equipment to receive a PDCCH (Physical Downlink Control Channel) for RMSI (Remaining Minimum System Information). The method comprises: receiving an SS/PBCH block containing an SS (Synchronization Signal) and a PBCH (Physical Broadcasting Channel); obtaining information related to a CORESET (Control resource set) for the PDCCH; and receiving the PDCCH within the CORESET based on the information. The information includes an offset between a frequency position of the SS/PBCH block related to the COPRESET and a frequency position of the CORESET. Values of the offset are defined based on subcarrier spacing of the SS/PBCH block and a minimum channel bandwidth.

Abstract: Provided are a method and a device for generating a virtual bearer in a wireless communication system. A mobility management entity (MME) acquires context information for a packet data network (PDN) connection generated through a Wi-Fi network, and generates a virtual bearer in a cellular network on the basis of the acquired context information. The virtual bearer may be generated by various methods according to whether a PDN connection mapped to the PDN connection generated through the Wi-Fi network exists in the cellular network and whether a default bearer exists in the cellular network.

Abstract: A method for selecting, by a base station, HD mode or FD mode in a wireless communication system supporting an FDR scheme may comprise: a step of receiving, from a second terminal which receives interference from a first terminal, a value related to the signal to noise ratio (SNR) of the second terminal and a value related to the signal-to-interference-plus-noise ratio (SINR) of the second terminal; a step of measuring the SNR value and the SINR value of the base station; a step of calculating the channel capacity ratio between the HD mode and the FD mode by using the received value related to the SNR of the second terminal, the received value related to the SINR of the second terminal, the measured SNR value of the base station, and the measured SINR value of the base station; and a step of selecting either mode on the basis of the calculated channel capacity ratio between the HD mode and the FD mode.

Abstract: Disclosed is a method of receiving downlink control information and an apparatus therefore in a wireless access system supporting an enhanced physical downlink control channel. The method includes receiving, from an eNB, DCI transmission channel information that indicates which one of a physical downlink control channel (PDCCH) and the e-PDCCH is used to transmit the DCI, checking the starting symbol of the e-PDCCH when the DCI transmission channel information indicates that the e-PDCCH is used to transmit the DCI, and receiving the DCI by performing blind decoding on the e-PDCCH from the starting symbol of the e-PDCCH.

Abstract: A method of allocating resources according to the present invention comprises the steps of: allocating a signal having a first beam width from a first base station controlling a first cell to a predetermined resource; and allocating a signal, having a second beam width different from the first beam width, from a second base station controlling a second cell adjacent to the first cell to the resource. The signal having the first beam width may be a signal having a first priority, and the signal having the second beam width may be a signal having a second priority that is different from the first priority. Accordingly, a method for allocating resources is proposed which can stably receive signals even when a terminal that moves in a dense small cell structure is at a cell edge or a border region between cells.
