1. A wireless communication system comprising:
- a first transceiver and second transceiver, each of the first transceiver and second transceiver co-located to each other and each configured to transmit data to at least one user equipment using the same communications resources, according to a collision sense multiple access/collision avoidance (CSMA/CA) protocol; and
a processor to;
identify data transmission sent from the second transceiver to the at least one user equipment by detecting a signal preamble from the second transceiver by measuring a time difference between when the second transceiver transmits the signal preamble and when the first transceiver receives the signal preamble, andallow data transmission from the first transceiver simultaneously with the data transmission sent from the second transceiver to the at least one user equipment, on one frequency.

Abstract
A wireless communication system may include a first transceiver co-located with a second transceiver. The first and second 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 identify data transmission from the second transceiver and allow data transmission from the first transceiver simultaneously with data transmission from the second transceiver, on one frequency.
