Abstract
User equipment of a communication system in one aspect obtains data indicative of the position of a satellite, and obtains data indicative of the position of the user equipment. The user equipment computes a delay measure based on the data indicative of the position of the satellite and the data indicative of the position of the user equipment, and adjusts the timing of a communication transmitted from the user equipment to the satellite based on the delay measure. In an illustrative embodiment, the user equipment receives data indicative of position and velocity of the satellite, and adjusts both timing and frequency of the communication based on the position and velocity data. The timing and frequency adjusted communication may then be transmitted to the satellite over a unicast uplink channel.
