US 10,122,500 B2 · Efficient sparse network resource usage and connection release

Abstract

This disclosure relates to techniques for efficient sparse network resource usage and connection release procedures. According to some embodiments, a wireless device may utilize techniques for efficiently releasing a radio resource control (RRC) connection, including techniques that avoid or reduce the occurrence of random access procedures when out-of-sync with the network when the RRC connection is being released. In some embodiments, a wireless device may utilize techniques for efficiently sparsely using network uplink resources, including techniques that avoid or reduce the occurrence of random access procedures to regain timing alignment to perform uplink communication when out-of-sync with the network.

Dependent claims

An apparatus, comprising:

a processing element configured to cause the apparatus to:
establish a radio resource control (RRC) connection with a base station of a cellular network;
receive connection release timer configuration settings from the base station, wherein a connection release timer for the RRC connection at the apparatus operates according to the configuration settings received from the base station;
determine to release the RRC connection based on expiry of the connection release timer without receiving an RRC connection release message from the base station;
and
release the RRC connection without sending a radio link control (RLC) layer acknowledgement message indicating that the RRC connection has been released to the base station.
