Abstract: A method for a device-to-device (D2D) communication in a wireless communication system is discussed. The method performed by a user equipment (UE) includes measuring a D2D received signal strength indicator (RSSI) for each resource region for the D2D communication, the D2D RSSI representing a received signal strength per symbol in the resource region; obtaining ratio information indicating a ratio of D2D resource regions having a higher D2D RS SI than a specific threshold within a resource pool for the D2D communication; and transmitting a measurement report including the ratio information to a base station.

Abstract: The present invention relates to a method for an NR (New Radio Access Technology) user equipment to transmit and receive a signal in a wireless communication system and an apparatus therefor. The method comprises the steps of checking a PDCCH (Physical Downlink Control Channel) order and, if the PDCCH order is checked, initiating a random access procedure. In this case, if a first uplink carrier and a second uplink carrier are configured, the random access procedure is configured to transmit a random access preamble via a specific uplink carrier corresponding to an indicator associated with the PDCCH order among the first uplink carrier and the second uplink carrier.

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: 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.

Abstract: A user equipment for performing multi-RAT concurrent transmission according to an embodiment of the present invention receives, from a base station, information on subframe sets and power management parameters to be applied to each of the subframe sets, sets the maximum transmission power of each of a first RAT signal and a second RAT signal using the power management parameters, and transmits at least one of the first RAT signal and the second RAT signal based on the set maximum transmission power. The subframe sets may include a first subframe set in which only transmission of the first RAT signal is allowed and a second subframe set in which multi-RAT concurrent transmission is allowed, and the power management parameters may include a parameter for limiting the maximum transmission power of the second RAT signal to be transmitted concurrently with the first RAT signal in the second subframe set.
