Abstract
The initial beam access method for a mobile station in a mmWave cellular network having a base station and multiple mobile stations includes a method having steps of probing a channel for information about the base station from the multiple mobile stations; receiving information from the multiple mobile stations on the direction of the base station in relation to a reference point; and adjusting the direction of the base station based on the received information and the reference point using a digital compass.

An initial beam access method for a mobile station in a mmWave cellular network having a base station and multiple mobile stations, the method comprising the steps of:
- upon entering a coverage area of a base station transmitting a directional signal from a beamforming antenna array, probing the coverage area with a low power omnidirectional antenna for directional signal parameters for contacting the base station provided by at least one of the multiple mobile stations already in the coverage area;
- receiving the directional signal parameters from at least one of the multiple mobile stations;
- adjusting the directional signal parameters received from the at least one of the multiple mobile stations using a digital compass to obtain reference parameters relative to magnetic north;
- and
- inputting the adjusted reference parameters to the mobile station's beamforming antenna to make contact with the base station.
A method for providing initial beam access in a mmWave cellular network, the network comprising:
- a base station configured for transmitting a directional signal beam through a beamformer array;
- a plurality of mobile stations, each of the mobile stations being configured for communicating with the base station through a beamformer antenna, configured for communicating with neighboring mobile stations by low power omnidirectional transmission and configured with a digital compass for locating the base station's beamformer array relative to magnetic north,
- the method for providing initial beam access to the base station comprising:
- the step of a single one of the plurality of mobile stations already in contact with the base station transmitting parameters for communicating with the base station's beamformer array to a single neighboring mobile station by low power omnidirectional signal.
