SYSTEM AND METHODS FOR ADAPTIVE PER-USER MULTIPATH CONTROL FOR SPATIAL MULTIPLEXING GAIN IN MIMO SYSTEMS

摘要

Disclosed herein is a system, apparatus, and method for adaptive per-user multipath control for spatial multiplexing gain in MIMO systems. Transmission parameters relating to Cyclic Shifts and/or Radio Frequency (RF) antenna beams are modified and tested to find optimal transmission parameters that enable better exploitation of multipath RF propagation and therefore better spatial multiplexing gain.

1. A non-transitory computer readable medium comprising instructions which, when executed by one or more devices, cause performance of operations comprising:
transmitting a first plurality of packets from a first device to a second device, the first plurality of packets being transmitted using a plurality of radio frequency chains, each radio frequency chain being associated with a different cyclic shift value in a first set of cyclic shift values; based on performance information, dynamically modifying at least one cyclic shift value in the first set of cyclic shift values to obtain a second set of cyclic shift values; and transmitting a second plurality of packets from the first device to the second device, the second plurality of packets being transmitted using the plurality of radio frequency chains, each radio frequency chain being associated with a different cyclic shift value in the second set of cyclic shift values.
