Abstract
Provided are a method for skipping contention resolution. According to an embodiment of the present disclosure, the method includes leaving radio resource control (RRC) connected state, while leaving RRC connected state, receiving information on timing advance in a paging occasion, adapting the timing advance and performing transmission based on the adapted timing advance.
Claims12
A method performed by a wireless device in a wireless communication system, the method comprising:
- receiving, from a network via a serving cell, a radio resource control (RRC) release message,
- leaving a radio resource control (RRC) connected state and entering an RRC idle state based on the RRC release message, wherein the RRC release message includes information on a time alignment timer for uplink transmission in the RRC idle state based on a configured grant;
- and
- while in the RRC idle state:
- starting the time alignment timer based on the information;
- and
- performing the uplink transmission based on the configured grant while the time alignment timer is running.
A wireless device in a wireless communication system, the wireless device comprising:
- at least one transceiver;
- at least one processor;
- and
- at least one computer memory operably connectable to the at least one processor and storing instructions that, based on being executed by the at least one processor, performs operations comprising:
- receiving, from a network via a serving cell, a radio resource control (RRC) release message,
- leaving a radio resource control (RRC) connected state and entering an RRC idle state based on the RRC release message, wherein the RRC release message includes information on a time alignment timer for uplink transmission in the RRC idle state based on a configured grant;
- and
- while in the RRC idle state:
- starting the time alignment timer based on the information;
- and
- performing the uplink transmission based on the configured grant while the time alignment timer is running.
A wireless device in a wireless communication system, the wireless device comprising:
- at least one memory;
- and
- at least one processor, operatively coupled to the at least one memory, and configured to:
- obtain a radio resource control (RRC) release message,
- control the wireless device to leave a radio resource control (RRC) connected state and enter an RRC idle state based on the RRC release message, wherein the RRC release message includes information on a time alignment timer for uplink transmission in the RRC idle state based on a configured grant;
- and
- while in the RRC idle state:
- start the time alignment timer based on the information;
- and
- generate the uplink transmission based on the configured grant while the time alignment timer is running.
