Efficient network hand-off utilizing stored beam-forming information

摘要

A system and method for performing efficient network hand-off (e.g., of a mobile communication device) utilizing stored beam-forming information. For example and without limitation, before determining to perform a particular hand-off, various aspects may comprise storing beam-forming information associated with the particular hand-off. Various aspects may also, for example, comprise determining to perform the particular hand-off. Various aspects may additionally, for example, comprise (e.g., after determining to perform the particular hand-off) accessing the stored beam-forming information associated with the particular hand-off to be performed. Various aspects may further, for example, comprise utilizing the accessed beam-forming information to form a communication beam to utilize for performing the particular hand-off.

主权项

1. A mobile communication device comprising:
a communication system configurable for radio communication with one or more remote radios, the communication system including beamforming circuitry responsive to stored beamforming information to develop one or more directed transmission beams in particular directions corresponding to the one or more remote radios; a location determining device configured to determine location information defining current location of the mobile communication device; a processor in data communication with the communication system and the location determining device, the processor configured to receive from the location determining device the location information defining the current location of the mobile communication device and to retrieve stored beamforming information associated with the current location of the mobile communication device and to provide the retrieved beamforming information to the communication system for development of one or more respective directed transmission beams in particular directions corresponding to one or more respective remote radios providing radio coverage to locations including the current location of the mobile communication device; and the processor further configured to retrieve the stored beamforming information for a communication handoff between a first remote radio and a second remote radio of the one or more radios, including first beamforming information for forming a first directed transmission beam in a particular direction corresponding to the first remote radio at the current location of the mobile communication device and second beamforming information for forming a second directed transmission beam in a particular direction corresponding to the second remote radio at the current location of the mobile communication device.
