Document Type and Number:
WIPO Patent Application WO/2019/093813
Kind Code:
A1
Abstract:
A method, performed by a user equipment (UE), of transmitting and receiving signals in a wireless communication system, according to an embodiment, includes receiving a logical channel release request from a next-generation node B (gNB), determining a logical channel to release, an operation mode of the logical channel to release, and whether a packet data convergence protocol (PDCP) layer apparatus connected to the logical channel is re-established, based on the logical channel release request, and performing PDCP data recovery based on the determination result.
