Abstract
A method, performed by a user equipment (UE), of performing communication in a handover process includes receiving uplink (UL) grant configuration information via an RRC reconfiguration message, selecting a SSB among a plurality of SSBs included in the UL grant information, determining a UL grant corresponding to the selected SSB and a HARQ process corresponding to the UL grant based on the UL grant information and transmitting a reconfiguration complete message in the determined UL grant corresponding to the selected SSB using a HARQ process.

A method of performing communication in a wireless communication system by a user equipment (UE), the method comprising:
- receiving uplink (UL) grant configuration information via a radio resource control (RRC) release message;
- selecting a synchronization signal block (SSB) among at least one SSB identified based on the UL grant configuration information;
- identifying a UL grant corresponding to the selected SSB;
- identifying a hybrid automatic repeat request (HARQ) process corresponding to the identified UL grant based on the UL grant configuration information;
- and
- transmitting a UL medium access control protocol data unit (MAC PDU) based on the identified UL grant using the identified HARQ process in an RRC INACTIVE state.
A method of performing communication in wireless communication system by a base station, the method comprising:
- transmitting uplink (UL) grant configuration information via a radio resource control (RRC) release message;
- and
- receiving, from a user equipment (UE) in an RRC INACTIVE state, a UL medium access control protocol data unit (MAC PDU) based on a UL grant using a hybrid automatic repeat request (HARQ) process,
- wherein:
- a synchronization signal block (SSB) among at least one SSB identified based on the UL grant configuration information is selected at the UE,
- the UL grant corresponding to the selected SSB is identified at the UE, and
- the HARQ process corresponding to the identified UL grant is identified based on the UL grant configuration information.
A user equipment (UE) of performing communication in wireless communication system, the UE comprising:
- a transceiver;
- and
- a processor configured to:

- identify a hybrid automatic repeat request (HARQ) process corresponding to the identified UL grant based on the UL grant configuration information;
- and
- transmit, via the transceiver, a UL medium access control protocol data unit (MAC PDU) based on the identified UL grant using the identified HARQ process in an RRC INACTIVE state.
A base station of performing communication in wireless communication system, the base station comprising:
- a transceiver;
- and
- a processor configured to:
- transmit, through the transceiver, uplink (UL) grant configuration information via a radio resource control (RRC) release message;
- and
- receive, via the transceiver, from a user equipment (UE) in an RRC INACTIVE state, a UL medium access control protocol data unit (MAC PDU) based on a UL grant using a hybrid automatic repeat request (HARQ) process,
- wherein:
- a synchronization signal block (SSB) among at least one SSB identified based on the UL grant configuration information is selected at the UE,
- the UL grant corresponding to the selected SSB is identified at the UE, and
- the HARQ process corresponding to the identified UL grant is identified based on the UL grant configuration information.
