CODEBOOK-BASED UPLINK TRANSMISSION METHOD IN WIRELESS COMMUNICATION SYSTEM AND DEVICE THEREFOR

摘要

Disclosed are a codebook-based uplink transmission method in a wireless communication system and a device therefor. Particularly, a method for a user equipment (UE) performing codebook-based uplink transmission in a wireless communication system comprises the steps of: receiving from a base station downlink control information (DCI) for physical uplink shared channel (PUSCH) scheduling comprising the number of layers and precoding information; determining a precoder on the basis of the precoding information and the number of the layers; and transmitting a PUSCH to which the determined precoder is applied to the base station, wherein the DCI can further comprise a phase coefficient and an amplitude coefficient applied to the precoder.
