Abstract:
1. A communication node comprising: a plurality of antennas; a plurality of radio circuitries configured to transmit and receive signals via the plurality of antennas; and a baseband processor, wherein said communication node is located within a clear channel assessment (CCA) range of a neighboring node, wherein the communication node and the neighboring node share a co-channel in compliance with an IEEE 802.11 standard, wherein the baseband processor is configured to set uplink transmit weights after said neighboring node has transmitted a preamble, for transmitting a signal power level of said communication node, as received by said neighboring node, below a signal power level associated with the CCA range, at one or more of the antennas of said neighboring node, wherein said communication node is a station configured to be served by the access point (AP) serving said communication node, and the neighboring node is an AP which is serving its respective stations, and wherein said station and APs operate in compliance with the IEEE 802.11 standard, wherein said station monitors Modulation Coding Scheme (MCS) transmitted by said neighboring AP, and further reduces transmit power if MCS <4, by a DELTA
