Abstract: A method of performing contention based multiple access (MA) by a base station in a wireless communication system, includes receiving information regarding a best beam ID (identifier) from each user equipment (UE), allocating a resource for contention based multiple access per beam based on a number of best beam ID per beam obtained from the information regarding the best beam ID received from the each UE, and transmitting information regarding the resource for the contention based multiple access allocated per beam, to the each UE. In this case, an amount of the resource allocated for the contention based multiple access per beam is in proportion to the number of best beam ID per beam.

Abstract: A method by which a transmission user equipment (UE) transmits a sounding reference signal (SRS) in a wireless communication system, according to the present disclosure, can comprise the steps of: receiving, from a base station, first configuration information including a timing advance and/or a timing advance offset; receiving, from the base station, second configuration information including SRS configuration; and transmitting an SRS to a reception UE on the basis of the first configuration information and the second configuration information. The timing advance is the same as the downlink reception timing of the reception UE, and the timing advance offset can be set to transmit the SRS. The timing advance can have a value corresponding to the downlink reception timing of the reception UE.

Abstract: In a wireless communication system, a physical broadcast channel (PBCH) is encoded based on a Polar code and then is transmitted. Half-frame information within the PBCH is mapped to a bit position 247 among bit positions of the Polar code and synchronization signal and PBCH block (SSB) index information within the PBCH is mapped to bit positions 253, 254, and 255 of the Polar code.
