Managing handover procedures of two or more modems from a serving base station to a target base station includes receiving at least one message indicative of at least one measurement report of radio conditions from at least one modem of the two or more modems; determining, based on the at least one message, whether to handover the two or more modems from the serving base station to the target base station; and upon determining to handover the two or more modems from the serving base station to the target base station, indicating to each of the two or more modems to send to the serving base station a measurement report configured to trigger a respective handover procedure from the serving base station to the target base station.

Handover management in air-to-ground wireless communication

Methods, systems, and devices are described for establishing a wireless communications link at an aircraft terminal (AT). An AT may determine a timing offset based on the propagation delay between the AT and a ground station, which in some cases may be more than 100 kilometers away. The AT may then transmit an initial access message to the ground station based on the determined timing offset. In some embodiments, the AT may receive an access response message from the ground station that includes a timing alignment value and adjust the timing offset based on this value. The AT may transmit a connection message to the ground station that includes AT location information. This information may be used by the ground station to facilitate beamforming.
