Network Synchronization for System Configuration Exchanges

摘要

This disclosure relates to techniques for avoiding loss of synchronization between a cellular device and a cellular network. According to some embodiments, a wireless device and a base station may perform a handshake procedure to select configuration parameters for cellular communication. The handshake procedure may establish a system frame number and subframe number at which the selected configuration parameters take effect. The wireless device and the base station may implement the selected configuration parameters at the selected system frame number and subframe number.

主权项

1. An apparatus, comprising:
a processing element configured to: perform a handshake procedure with a cellular base station (BS) to exchange configuration parameters for cellular communication between the UE and the BS, wherein the selected configuration parameters comprise at least discontinuous reception configuration parameters, wherein the handshake procedure establishes a system frame number and subframe number at which the selected configuration parameters take effect; initiate discontinuous reception operation according to the configuration parameters at the indicated system frame number and subframe number; and initiate a timing alignment timer at the indicated system frame number and subframe number.
