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 is provided for receiving a downlink signal through an Enhanced Physical Downlink Control Channel (EPDCCH) in a wireless communication system by a user equipment (UE). The UE receives a parameter indicating a quasi co-location behavior type is. The UE further receives a demodulation reference signal (DMRS) associated with the EPDCCH. The UE attempts to decode the EPDCCH based on the DMRS. If a transmission mode configured in the UE is a transmission mode 10, the UE assumes that antenna ports of the DMRS are quasi co-located with antenna ports of a reference signal determined by the parameter.

Abstract: The present invention relates to a method and a device for a New Radio (NR) access technology base station transmitting a signal in a wireless communication system. Specifically, the method comprises the steps of: checking a configuration associated with a subframe assigned to a Long Term Evolution (LTE) band; according to the checked configuration, determining a resource region in which a NR downlink signal may be assigned in the LTE band in a specific subframe shared for NR communication; and transmitting a control resource set (CORSET) via the resource region. The NR UE is capable of communicating with at least one of another UE, a UE related to an autonomous driving vehicle, a base station or a network.

Abstract: A user equipment, according to one embodiment of the present invention, monitors candidates of a control channel which schedules system information in a configured specific CORESET based on a PBCH signal, obtains the system information scheduled by the control channel, and obtain a only part of entire parameters for configuring the specific CORESET from the PBCH signal. In this case, the user equipment can monitor the candidates of the control channel by assuming that remaining parameters for configuring the specific CORESET not obtained through the PBCH signal are fixed as follows a size of 1 REG bundle is fixed to 6 REGs, a CCE-to-REG mapping type is fixed to interleaving, a row size of an interleaver for interleaving is fixed to 2, and a precoder granularity which is a unit of the same precoding assumption is fixed to 1 REG bundle.

Abstract: Provided are a method and an apparatus for receiving a downlink signal in a wireless communication system. The method includes receiving resource block assignment information including a bitmap and receiving the downlink signal through a resource block group (RBG) indicated by the bitmap in a bandwidth part. A total number of resource block groups (RBGs) in the bandwidth part is determined based on an index of a start resource block of the bandwidth part, a size of the bandwidth part, and a size of one resource block group.
