Abstract
A method and apparatus for performing uplink transmission is provided. The method includes receiving an RRC Release message from a base station, The RRC Release message includes SuspendConfig, causing a wireless device to transition to the RRC_INACTIVE state in response to receiving the RRC Release message and to perform cell selection. The wireless device initiates an RRC CONNECTION RESUME in the cell, and perform a PUSCH transmission.
Claims20
A method performed by a base station, the method comprising:
- receiving, from a wireless device, a first Radio Resource Control (RRC) message, wherein the first RRC message comprises one or more capability parameters;
- transmitting, to the wireless device and via a first cell, a second RRC message that causes an RRC state transition, wherein the second RRC message comprises configuration information for an RRC inactive state;
- and
- transmitting, to the wireless device and via the first cell, a paging message;
- receiving, from the wireless device and via the first cell, a common control channel (CCCH) service data unit (SDU) indicating a resume cause value relating to small data transmission (SDT), wherein the receiving the CCCH SDU is based on:
- a configured grant (CG);
- the paging message comprising:
- a first identifier of the wireless device;
- and
- an indication associated with SDT;
- CG-SDT being configured on a selected uplink carrier;
- and
- a time alignment (TA) of the CG being valid;
- and
- after the receiving the CCCH SDU, performing, via the first cell and based on a second identifier of the wireless device, data communication with the wireless device.

A base station comprising:
- a transceiver;
- a memory;
- and
- a controller coupled to the transceiver and the memory, wherein the controller is configured to cause the base station to:
- receive, from a wireless device, a first Radio Resource Control (RRC) message, wherein the first RRC message comprises one or more capability parameters;
- transmit, to the wireless device and via a first cell, a second RRC message that causes an RRC state transition, wherein the second RRC message comprises configuration information for an RRC inactive state;
- and
- transmit, to the wireless device and via the first cell, a paging message;
- receive, from the wireless device and via the first cell, a common control channel (CCCH) service data unit (SDU) indicating a resume cause value relating to small data transmission (SDT), wherein receiving the CCCH SDU is based on:
- a configured grant (CG);
- the paging message comprising:
- a first identifier of the wireless device;
- and
- an indication associated with SDT;
- CG-SDT being configured on a selected uplink carrier;
- and
- a time alignment (TA) of the CG being valid;
- and
- after receiving the CCCH SDU, perform, via the first cell and based on a second identifier of the wireless device, data communication with the wireless device.
