Abstract
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.
