Abstract
A wireless device, in a radio resource control (RRC) idle state or RRC inactive state, transmits, to a base station, a message. The message comprises first data associated with a small data transmission (SDT) procedure and an RRC request message. While the wireless device is in the RRC idle state or RRC inactive state, the wireless device receives, from the base station, an indication of an uplink resource, transmits, via the uplink resource, second data associated with the SDT procedure, and receives, from the base station and after the transmitting the second data, an RRC release message.
Claims20
A method comprising:
- receiving, by a wireless device from a base station, a first radio resource control (RRC) release message comprising a suspend configuration associated with a first bandwidth part (BWP);
- and
- while the wireless device is in an RRC idle state or an RRC inactive state:
- transmitting, by the wireless device, based on the suspend configuration:
- first data associated with a small data transmission (SDT) procedure;
- and
- an RRC message requesting to resume an RRC connection;
- receiving, by the wireless device, a second RRC release message comprising a subsequent configuration associated with a second BWP;
- and
- transmitting via the second BWP, by the wireless device based on the subsequent configuration, second data associated with the SDT procedure.
A wireless device comprising one or more processors and memory storing instructions that, when executed by the one or more processors, cause the wireless device to:
- receive, from a base station, a first radio resource control (RRC) release message comprising a suspend configuration associated with a first bandwidth part (BWP);
- while in an RRC idle state or an RRC inactive state:
- transmit, based on the suspend configuration:
- first data associated with a small data transmission (SDT) procedure;
- and
- an RRC message requesting to resume an RRC connection;
- receive a second RRC release message comprising a subsequent configuration associated with a second BWP;
- and
- transmit via the second BWP, based on the subsequent configuration, second data associated with the SDT procedure.
A system, comprising:
- a wireless device comprising:
- one or more processors and memory storing instructions that, when executed by the one or more processors, cause the wireless device to:
- receive, from a base station, a first radio resource control (RRC) release message comprising a suspend configuration associated with a first bandwidth part (BWP);
- while in an RRC idle state or an RRC inactive state:
- transmit, based on the suspend configuration:
- first data associated with a small data transmission (SDT) procedure;
- and
- an RRC message requesting to resume an RRC connection;
- receive a second RRC release message comprising a subsequent configuration associated with a second BWP;
- and
- transmit via the second BWP, based on the subsequent configuration, second data associated with the SDT procedure
- a base station comprising:
- one or more processors and memory storing instructions that, when executed by the one or more processors, cause the base station to:
- transmit the first RRC release message;
- receive the first data and the RRC message requesting to resume the RRC connection;
- transmit the second RRC release message;
- and
- receive the second data.
