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.
Claims17
A method performed by a wireless device operating in a wireless communication system, the method comprising:
- receiving, from a network on 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 a resource index related to a configured grant;
- and
- while in the RRC idle state, performing an uplink transmission based on the configured grant at resources indicated by the resource index.
A wireless device configured to operate 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, perform operations comprising:
- receiving, via the at least one transceiver from a network on 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 a resource index related to a configured grant;
- and
- while in the RRC idle state, performing, via the at least one transceiver, an uplink transmission based on the configured grant at resources indicated by the resource index.
A processing apparatus configured to operate in a wireless communication system, the wireless device comprising:
- at least one memory;
- and
- at least one processor, coupled to the at least one memory, and configured to perform operations comprising:
- obtaining 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 a resource index related to a configured grant;
- and
- while in the RRC idle state, performing an uplink transmission based on the configured grant at resources indicated by the resource index.
