Abstract: A method of supporting signal transmission/reception using at least two RATs and apparatus therefor are disclosed. The present invention includes, when a user equipment is simultaneously accessing a 1st base station of a 1st communication network supportive of a 1st RAT and a 2nd base station of a 2nd communication network supportive of a 2nd RAT, receiving a setup message indicating a termination of a connection to the 2nd base station from the 1st base station and terminating the connection to the 2nd base station. Before the connection to the 2nd base station is terminated, the user equipment transceives data for a specific traffic type via the 2nd base station and also transceives data except the specific traffic type via the 1st base station. If the connection to the 2nd base station is terminated, the user equipment transceives the data for the specific traffic type via the 1st base station.

Abstract: A method and apparatus for service data adaptation protocol (SDAP) configuration for a destination in sidelink communication is provided. A wireless device establishes a service data adaptation protocol (SDAP) entity based on a SDAP configuration per destination of a sidelink communication. This can be achieved by the wireless device receiving a configuration of one or more sidelink radio bearers (SLRBs), which includes an SDAP configuration for each of the one or more SLRBs. Each SDAP configuration, in turn, includes a list of Quality of Service Flow Identities (QFIs) for a corresponding destination, from among one or more destinations, to be mapped to a corresponding SLRB. One or more transmitting SDAP entities can then be established for each of the one or more destinations.

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.
