Abstract
This specification describes, in part, a technique for dynamic assignment of multiple antennas to different radio subsystems in a wireless device. The technique may include using an adaptive algorithm to allocate antennas to different radio subsystems as a function of, for example, application requirements, power requirements, and/or channel/network conditions. The specification also describes, in part, a technique for adaptively optimizing the use of the assigned antennas and other transmission parameters for each radio subsystem.
Claims23
A method comprising:
- initializing a number of spatial streams to a starting value;
- repeating until the number of spatial streams is greater than a maximum number of spatial streams:
- optimizing use of antennas to support the number of spatial streams;
- optimizing transmission parameters;
- determining throughput for the number of spatial streams and the optimized transmission parameters;
- storing the number of spatial streams and optimized transmission parameters as optimal, and throughput as maximum throughput, if throughput is higher than a prior maximum throughput;
- incrementing the number of spatial streams.
A method comprising:
- assigning a minimum number of antennas to each of a plurality of operational radio subsystems;
- assigning additional antennas to meet minimum performance criteria for first one or more operational radio subsystems of the plurality of operational radio subsystems;
- assigning remaining antennas, if any, to second one or more operational radio subsystems of the plurality of operational radio subsystems.
A wireless device comprising:
- a plurality of antennas;
- a plurality of radio subsystems;
- an antenna multiplexer dynamically coupling subsets of the plurality of antennas to one or more of the radio subsystems in accordance with a switching algorithm embodied in a computer-readable medium.
