Wi-Fi radio distribution network stations and method of operating Wi-Fi RDN stations
First Claim
1. A Wi-Fi radio distribution network (RDN) station for use in a wireless communications network comprising a plurality of wireless stations, the Wi-Fi RDN station comprising:
- a multiple-input-multiple-output (MIMO) receiving system configured to operate in accordance with a channel estimation MIMO receiving scheme; and
a RDN connected to the MIMO receiving system, the RDN comprising at least one beamformer arranged to be fed by two or more antennas, wherein each of the beamformers includes a combiner configured to combine signals coming from a plurality of antennas associated with the respective beamformer into a single signal, and, wherein the MIMO receiving system is configured to select whether to perform channel estimation using a single antenna or beamforming, said selection being based on one or more packets addressed to one or more wireless stations in the communications network other than the Wi-Fi RDN station,wherein the MIMO receiving system is configured to determine whether an access point (AP) serving the Wi-Fi RDN station is to send a packet to a station other than the Wi-Fi RDN station andif the determination is positive perform said channel estimation using a single antenna; and
if the determination is negative use one or more alternative methods for beamforming or channel estimation or both, andwherein the one or more alternative methods comprise;
beamforming based on one or more packets addressed to one or more wireless stations in the communications network other than the Wi-Fi RDN station; and
channel estimation or beamforming based on one or more packets addressed to the Wi-Fi RDN station, andwherein the MIMO receiving system is configured to determine the level of packets addressed to stations in the communications network other than the Wi-Fi RDN station based on the ratio between air-time or number of packets addressed to other stations and air-time or number of packets addressed to the Wi-Fi RDN station over a period of time.

Abstract
A Wi-Fi radio distribution network (RDN) station is provided for use in a wireless communications network comprising a plurality of wireless stations. The Wi-Fi RDN station comprises a multiple-input-multiple-output (MIMO) receiving system configured to operate in accordance with a channel estimation MIMO receiving scheme; and a RDN connected to the MIMO receiving system. The RDN comprises at least one beamformer arranged to be fed by two or more antennas, wherein each of the beamformers includes a combiner configured to combine signals coming from a plurality of antennas associated with the respective beamformer into a single signal. The MIMO receiving system is configured to perform one or both of channel estimation using a single antenna or beamforming. Both channel estimation and beamforming may be based on one or more packets addressed to one or more wireless stations in the communications network other than the Wi-Fi RDN station.
