  • Patent number: 11665570
    Abstract: An electronic device (14) detects when a downlink reference signal has not been received from a base station (12), and initiates transmission of an uplink reference signal (64) in response to determining that certain trigger criteria have been satisfied. Upon receiving the uplink reference signal (64) or a notification signal (60) from the electronic device (14), the base station (12) can perform various actions to maintain network mobility and handover performance. In this manner, the disclosed approach allows a network to maintain mobility and handover performance even when a base station (12) is unable to transmit downlink reference signals due to an occupied communication channel.
