Title: RADIO LINK MONITORING TEST PROCEDURES FOR WIRELESS DEVICES
Abstract:
A technique includes maintaining a signal-to-noise ratio of the transmitted reference signals to be less than a lower signal-to-noise ratio threshold for a first period of time that is a sufficient length of time to allow a correctly operating user device to detect an out-of-sync status and subsequently declare a radio link failure with respect to the connection, increasing, after the maintaining, the signal-to-noise ratio of the reference signals transmitted to the user device from the second signal-to-noise ratio to a third signal-to-noise ratio, wherein the third signal-to-noise ratio is greater than an upper signal-to-noise ratio threshold, after the increasing, sending, by the network device to the user device, an uplink resource grant, and confirming that the network device does not receive an uplink transmission from the user device in response to the uplink resource grant within a second period of time.
