Title:
METHOD FOR TRANSMITTING AND RECEIVING SIGNALS IN WIRELESS COMMUNICATION SYSTEM, AND DEVICE SUPPORTING SAME
Document Type and Number:
WIPO Patent Application WO/2021/066602
Kind Code:
A1
Abstract:
The present invention relates to a method carried out by a user equipment in a wireless communication system and a device supporting same and, more particularly, to a method and a device supporting same, the method comprising the steps of: obtaining a message A related to a random access procedure; transmitting the message A; and in response to the message A, receiving a message B related to the random access procedure, wherein: the message A includes a physical random access channel (PRACH) preamble and a physical uplink shared channel (PUSCH); the PUSCH is transmitted on the basis of information related to a PUSCH configuration for the message A received; on the basis that the information related to the PUSCH configuration includes information related to the indication of a code division multiplexing (CDM) group for a demodulation reference signal (DMRS) for the PUSCH, the CDM group is set to be a group indicated by information related to the indication of the CDM group among two preset groups; after the random access procedure, communication is carried out; on the basis of the communication, a physical downlink shared channel (PDSCH) is received; and on the basis that discontinuous reception (DRX) is set, a physical downlink control channel (PDCCH) for the PDSCH is monitored within an on duration related to the DRX.
