Abstract
The present invention provides a method of operating a user equipment, UE device in communication with a non-terrestrial communication system comprising a plurality of transmission points, the method comprising in the UE device triggering a transmission of a measurement report dependent on a measurement by the UE device of a received signal parameter of a signal received from a transmission point of the system and a comparison of the measured parameter with a threshold, the threshold varying according to a predetermined function dependent on an expected position of the UE device with respect to the transmission point.
Claims11
A method of operating a user equipment, UE, device in communication with a non-terrestrial communication system comprising a plurality of transmission points, the method comprising:
- in the UE device periodically triggering a transmission of a measurement report, the measurement report comprising information dependent on a measurement by the UE device of a received signal parameter of a signal received from a transmission point of the non-terrestrial communication system, the periodic triggering being performed by the UE device with a periodicity, the periodicity being a predetermined time-variant function dependent on a time-dependent expected position of the UE device with respect to the transmission point;
- and
- transmitting the measurement report.
A user equipment, UE, device capable of communicating with a satellite communication system, the UE device being adapted to periodically generate measurement reports, wherein the UE device is arranged to send the measurement reports with a time varying periodicity, the time varying periodicity varying according to a predetermined time-variant function dependent on an expected change in position of a satellite of the satellite communication system.
A method for a non-terrestrial communication system to control a handover of a user equipment, UE, device from a first transmission point to a second transmission point, the method comprising:
- providing the UE device with configuration information for performing measurement reporting;
- instructing the UE device to periodically perform measurement reporting with a time varying periodicity, the time varying periodicity varying according to a pre-determined time-variant function dependent on a time-dependent expected position of the UE device with respect to the first transmission point;
- receiving from the UE device measurement reports in accordance with the configuration information;
- and
- in an event of a determination based on the measurement reports that a handover from the first transmission point to the second transmission point would be beneficial, issuing a handover command to the UE device.
