Abstract: A method of transmission power control in a wireless communication system, is discussed. The method can include performing a wide area network (WAN) transmission in a first subframe of a first carrier; and performing a sidelink transmission in a second subframe of a second carrier, wherein if the first subframe and the second subframe overlap in time, a maximum output power for either the WAN transmission in the first subframe or the sidelink transmission in the second subframe is determined on the basis of a maximum output power for the first subframe of the first 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 is provided with puncturing information indicating a resource to which downlink data is punctured among time-frequency resources to which the downlink data is allocated. The user equipment may decode the downlink data received in the time-frequency resource on the basis of the puncturing information. The downlink data may be mapped to the time-frequency resource by a combined method of a time-first resource mapping method and a frequency-first resource mapping method, or by a distributed resource mapping method.
