Document Type and Number:
WIPO Patent Application WO/2011/042847
Kind Code:
A3
Abstract:
The present invention relates to a method for operating a primary station comprising a transceiver for communicating with a plurality of secondary stations, said transceiver including at least two antennas, the method comprising the primary station transmitting to a secondary station for a single spatial channel at least one first set of reference symbols with a first antenna and at least one second set of reference symbols with a second antenna, the second set of reference symbols being orthogonal to the first set of reference symbols.
