Robust beam tracking and data communication in millimeter-wave mobile networks

A computer system for robust beam tracking and data communication, comprising:

• a processor device operatively coupled to a memory device, the processor device being configured to:
• divide, by a base station, time into frames each having two phases, a location probing phase and a data communication phase;
• determine a steady state analysis of the performance of beam tracking by the base station;
• formulate an optimization problem to obtain optimal frame structure maximizing steady state average throughput;
• in the location probing phase, use a fractional search policy to localize at least one mobile device by transmitting multiple probing packets over different time-slots and update information about a location of the at least one mobile device;
• and
• in the data communication phase, communicate with the at least one mobile device while expanding a beamwidth to compensate for possible mobility of the at least one mobile device.
