Abstract: A method of supporting signal transmission/reception using at least two RATs and apparatus therefor are disclosed. The present invention includes, receiving, at the user equipment concurrently connected a first base station of a first communication network supportive of a first RAT and a second serving base station of a second communication network supportive of a second RAT, a setup message indicating a handover from the second serving base station to a second target base station from a first base station, terminating a connection to the second serving base station, and establishing a connection to the second target base station. Before the connection to the second serving base station is terminated, data for a specific traffic type is transceived via the second serving base station. After the connection to the second target base station is established, the data for the specific traffic type is transceived via the second target base station. Data except the specific traffic type is transceived via the first base station.

Abstract: In the present disclosure, a UE transmits a random access preamble (RAP) on a physical random access channel (PRACH) and a common control channel (CCCH) service data unit (SDU) on a physical uplink channel (PUSCH). The UE receives a medium access control (MAC) protocol data unit (PDU) based on transmitting the RAP and the CCCH SDU. The MAC PDU may include a MAC PDU associated with a contention resolution identity (CRID) in the MAC PDU. The UE determines whether a MAC SDU is present or not in the MAC PDU, based on the MAC SDU indicator associated with a CRID in the MAC PDU in a state in which the CRID matches the CCCH SDU.

Abstract: The present invention relates to a method of transmitting buffer status report (BSR) by a node in a wireless communication system. In particular, the method includes the steps of: transmitting, to a parent node, a first BSR with starting a timer before receiving data from a child node; triggering a second BSR based on receiving the data from the child node; and based on the data not being transmitted to the parent node until expiration of the timer, transmitting, to the parent node, a scheduling request (SR) for transmission of the second BSR, wherein, based on the data being transmitted to the parent node before the expiration of the timer, the timer is stopped and the second BSR is canceled.
