Abstract
User equipment according to an embodiment of the present disclosure may: receive a radio resource control (RRC) release message including small data transmission (SDT) configuration information related to a configured grant (CG); switch to an RRC INACTIVE state; and, on the basis of a case in which a resource for the CG is activated on the basis of the SDT configuration information, transmit SDT data via the resource.
Claims12
A method of performing a small data transmission (SDT) procedure by a user equipment (UE) in a wireless communication system, the method comprising:
- receiving a radio resource control (RRC) release message including SDT configuration information;
- converting a current state to an RRC INACTIVE state based on the RRC release message;
- and
- performing the SDT procedure based on the SDT configuration information,
- wherein the SDT configuration information includes a configured grant (CG) configuration for the SDT procedure an uplink bandwidth part (BWP) configuration for the SDT procedure, and a downlink BWP for the SDT procedure,
- wherein the SDT configuration is configured for a specific cell, and
- wherein the UE stops a TAT (Time Alignment Timer) running for the SDT procedure based on an initiation of the SDT procedure for a cell different from the specific cell.
A user equipment (UE) for wireless communication, the UE comprising:
- a transceiver;
- and
- one or more processors,
- wherein the one or more processors are configured to:
- receive a radio resource control (RRC) release message including small data transmission (SDT) configuration information;
- convert a current state to an RRC INACTIVE state based on the RRC release message;
- and
- performing the SDT procedure based on the SDT configuration information, and
- wherein the SDT configuration information includes a configured grant (CG) configuration for the SDT procedure, an uplink bandwidth part (BWP) configuration for the SDT procedure, and a downlink BWP for the SDT procedure,
- wherein the SDT configuration is configured for a specific cell, and
- wherein the one or more processors are further configured to stop a TAT (Time Alignment Timer) running for the SDT procedure based on an initiation of the SDT procedure for a cell different from the specific cell.
A method of receiving a uplink data by a base station (BS) in a wireless communication system, the method comprising:
- transmitting, to a user equipment (UE), a radio resource control (RRC) release message including small data transmission (SDT) configuration information;
- and
- receiving the uplink data related to the SDT procedure,
- wherein the SDT configuration information includes a configured grant (CG) configuration for the SDT procedure, an uplink bandwidth part (BWP) configuration for the SDT procedure, and a downlink BWP for the SDT procedure,
- wherein the SDT configuration is configured for a specific cell, and
- wherein, based on the initiation of the SDT procedure for a cell different from the specific cell, a TAT (Time Alignment Timer) running for the SDT procedure is stopped.
