Document Type and Number:
WIPO Patent Application WO/2021/251765
Kind Code:
A1
Abstract:
Disclosed are a method for transmitting and receiving signals in a wireless communication system, and an apparatus supporting the method, wherein dual active protocol stack-based handover (DAPS HO) operation is carried out, and, on the basis of transmission, to a target master cell group, of a message comprising a physical random access channel (PRACH) and a physical uplink shared channel (PUSCH), an uplink signal different from the message is not transmitted to a source MCG in a first time period that overlaps with a second time period in which PRACH and PUSCH were transmitted.
