    Abstract: Disclosed is a method for performing, by a UE, carrier aggregation (CA) via a first carrier wave and a second carrier wave, on the basis of switching of a transmission chain, in a wireless communication system according to various embodiments. Disclosed are the method and apparatus therefor, the method comprising the steps of: reporting a first power headroom report (PHR) for the first carrier wave and a second PHR for the second carrier wave; receiving transmission chain switching information for changing a setting of a transmission chain for each of the first carrier wave and the second carrier wave; and assigning first transmission power for the first carrier wave and second transmission power for the second carrier wave, wherein one or more transmission chains are assigned to the second carrier wave via the transmission chain switching information, and when a power control value set for the second carrier wave is greater than first maximum output power of the one or more transmission chains, the second transmission power can be assigned on the basis of the number of all transmission chains for performing the CA and the number of the one or more transmission chains.

    Abstract: A method in which a UE transmits an uplink signal, based on a codebook, in a wireless communication system includes: receiving downlink control information (DCI) for determining a precoding matrix, which is applied to transmission of the uplink signal, from a base station; determining a precoding matrix that is applied to transmission of the uplink signal from a codebook subset related to transmission of the uplink signal, based on the DCI; and transmitting the uplink signal to the base station, based on the determined precoding matrix, in which, based on that differences of phase values applied to antenna ports for transmitting the uplink signal are changed in all pairs of antenna ports, the codebook subset includes at least one specific precoding matrix for full power transmission.

    Abstract: The present specification relates to a method by which a device performs data transmission or reception in a wireless communication system, comprising: performing an initial access operation with other devices; and transmitting first information (M−N) times and second information N times to the other devices, wherein M and N are respectively natural numbers, M is greater than N, and the first information and the second information are respectively the information related to timing adjustment, the first information has a value differing from that of the second information, and the data transmission or reception with the other devices is performed on the basis of a timing advance (TA) value, which is based on the average of all of the first information transmitted (M−N) times and the second information transmitted N times.

    Abstract: Disclosed herein are a method and a device for transmitting a message in an initial access procedure by a user equipment (UE) in a wireless communication system. According to the present disclosure, a UE may transmit to a base station capability information associated with transmission power of the UE and the information may include a subset including at least one transmit precoding matrix indicator (TPMI) supported by the UE. The UE may receive first control information for transmitting a message associated with an initial access and the control information may include a TPMI used for the UE to transmit the message. Thereafter, the UE may transmit to the base station the message by using transmission power determined based on the TPMI and the transmission power may be determined according to whether the TPMI is included in the at least one TPMI.
