MIMO WIRELESS COMMUNICATION METHOD AND SYSTEM

摘要

The present invention discloses a MIMO wireless communication method functioning through a main wireless communication device and comprising: acquiring a transmission opportunity; issuing an distributed MIMO initiation frame including a transmission duration, a number Ns1 of transmission spatial stream(s), and a number Nr1 of reception spatial streams which an intended receiver is operable to process; receiving an initial portion which an attendant wireless communication device sends in response to the distributed MIMO initiation frame, or issuing the initial portion after reaching a time limit; and transmitting a distributed MIMO packet to the intended receiver while the attendant wireless communication device is allowed to transmit another distributed MIMO packet to the intended receiver or another intended receiver concurrently, wherein the sum of the number Ns1 and a number Ns2 of transmission spatial stream(s) of the attendant wireless communication device is equal to or less than the number Nr1.

主权项

1. A multiple-input multiple-output (MIMO) wireless communication method to function through a main wireless communication device, comprising:
acquiring a transmission opportunity under a protocol indicating that any other device running after the transmission opportunity has to hold off transmission without a distributed MIMO frame from the main wireless communication device; issuing a distributed MIMO initiation frame including the transmission duration of the main wireless communication device, a number Ns1 of transmission spatial stream(s) of the main wireless communication device, and a number Nr1 of reception spatial streams which an intended receiver is operable to process; receiving an initial portion which an attendant wireless communication device sends in response to the distributed MIMO initiation frame, or issuing the initial portion after reaching a predetermined condition; and after receiving or issuing the initial portion, transmitting a distributed MIMO packet to the intended receiver while the attendant wireless communication device is allowed to transmit another distributed MIMO packet to the intended receiver or another intended receiver in the transmission duration of the main wireless communication device, wherein the sum of the number Ns1 and a number Ns2 of transmission spatial stream(s) of the attendant wireless communication device is equal to or less than the number Nr1.
