Abstract

The present disclosure relates to methods, a device and a system for evaluation of channel estimate. One method is performed in a first access point arranged to communicate with one or more wireless devices through information streams that are created using multiple co-located antennas. The method comprises transmitting or receiving a packet A, to/from, the first wireless device, wherein the packet A is transmitted using a precoder determined using the channel estimate, retrieving information about possibly interfering transmissions C between further access points in the vicinity of the first access point, and respective second wireless devices; wherein the information comprises location information and timing information related to the possibly interfering transmissions, determining spatial separations between the transmissions A and C and evaluating the channel estimate, based on the determined spatial separations.
