Abstract
A method for a UE for performing SDT is provided. The method includes receiving, from a BS, system information that includes a SIB1; determining whether to initiate an SDT procedure based on one or more conditions, the one or more conditions including the SIB1 including an SDT configuration; and initiating the SDT procedure in a case that the one or more conditions are fulfilled. A UE using the method is also provided.
Claims14
A method performed by a User Equipment (UE) for Small Data Transmission (SDT), the method comprising:
- receiving, from a Base Station (BS), system information that includes a System Information Block 1 (SIB1);
- initiating an SDT procedure in response to determining that a plurality of conditions is satisfied, the plurality of conditions comprising:
- the SIB1 including an SDT configuration, and
- an SDT-specific Reference Signal Received Power (RSRP) threshold being absent from the SDT configuration;
- in response to initiating the SDT procedure, determining whether a serving cell for the SDT procedure is configured with a Supplementary Uplink (SUL) carrier;
- and
- selecting a Normal Uplink (NUL) carrier as an Uplink (UL) carrier for the SDT procedure in response to determining that the serving cell is not configured with the SUL carrier.
A User Equipment (UE) for performing Small Data Transmission (SDT), the UE comprising:
- transmission and reception circuitry;
- and
- at least one processor coupled to the transmission and reception circuitry and configured to:
- receive, by the transmission and reception circuitry, from a base station (BS), system information that includes a System Information Block 1 (SIB1);
- initiate an SDT procedure in response to determining that a plurality of conditions is satisfied, the plurality of conditions comprising:
- the SIB1 including an SDT configuration, and
- an SDT-specific Reference Signal Received Power (RSRP) threshold being absent from the SDT configuration;
- in response to initiating the SDT procedure, determine whether a serving cell for the SDT procedure is configured with a Supplementary Uplink (SUL) carrier;
- and
- select a Normal Uplink (NUL) carrier as an Uplink (UL) carrier for the SDT procedure in response to determining that the serving cell is not configured with the SUL carrier.
