System and method for co-located and co-channel Wi-Fi access points

摘要

A wireless communication system may include a plurality of co-located transceivers. The plurality of transceivers may be configured to transmit data to at least one user equipment, according to a collision sense multiple access/collision avoidance (CSMA/CA) protocol. A processor may receive a signal preamble and a sender address of the signal preamble and determine whether the sender address is included in the stored list of addresses. If the sender address is included in the stored list of addresses, the processor may allow simultaneous data transmission from two or more of the co-located transceivers.

1. A wireless communication system comprising:
a plurality of transceivers co-located to each other and each configured to transmit data to at least one user equipment using the same frequency channel, according to a collision sense multiple access/collision avoidance (CSMA/CA) protocol, wherein the co-located transceivers are grouped together into one base station; a processor to:
initiate a clear channel assessment upon receipt of a data packet;determine whether a signal preamble is present in the data packet;if the signal preamble is not present in the data packet, terminate the clear channel assessment; andif the signal preamble is present in the data packet:
a) update a Network Allocation Vector (NAV) with a duration value from the received data packet,b) receive a sender address of the signal preamble,c) determine whether the preamble is from a co-located transceiver based on whether the sender address is included in a stored list of addresses of co-located transceivers, andd) allow simultaneous data transmission from two or more of the co-located transceivers, if the sender address is included in the stored list of addresses by resetting the NAV timer to zero.
