High Density Deployment Using Transmit or Transmit-Receive Interference Suppression with Selective Channel Dimension Reduction/Attenuation and Other Parameters

摘要

In a wireless local area network, each of multiple access points, in a high density deployment, are configured to suppress co-channel interference. A first access point having a plurality of antennas beamforms a transmission to a wireless client device within a null-space or with the weakest singular eigenmodes of a wireless channel between the first access point and at least one co-channel second access point. Techniques are presented herein for situations in which any given access point has two or more co-channel access points. In addition, an access point may perform receive side suppression with respect to a transmission (made by a co-channel access point to one of its associated wireless client devices) that is received from that co-channel access point.

主权项

1. A method comprising:
at a second access point, determining one or more antennas paths for which to disable reception in order to suppress co-channel interference associated with transmissions made by a first access point; and sending channel state information from the second access point to the first access point, the channel state information indicating which one or more antennas paths are to be disabled at the second access point.
