Abstract
The present invention relates to a method for communicating in a network, said network comprising a primary station and at least a first secondary station, wherein the first secondary station transmits to the primary station an indication of a first plurality of precoding vectors, wherein the number of first precoding vectors is greater than a preferred rank of transmission from the primary station to the first secondary station.
Claims15
A method for communicating in a network, said network comprising:
- a primary station;
- and
- at least a first secondary station, wherein the first secondary station transmits to the primary station an indication of a first plurality of precoding vectors, said indication comprises a number of said first plurality of precoding vectors greater than a preferred rank of transmission from the primary station to the first secondary station, and less than a number of receive antennas of the first secondary station, wherein the first secondary station selects the first plurality of precoding vectors depending on at least one of a correlation between the receive antennas of the first secondary station and a corresponding SINR for each precoding vector.
A secondary station communicating in a network with a primary station, the secondary station comprising:
- transmitting means arranged for transmitting an indication of a first plurality of precoding vectors, said indication comprising a number of first precoding vectors is greater than a preferred rank of transmission from the primary station to the secondary station, and less than a number of receive antennas of the secondary station, wherein the secondary station selects the first plurality of precoding vectors depending on at least one of a correlation between the receive antennas of the secondary station and a corresponding SINR for each precoding vector.
A primary station comprising:
- receiving means arranged for receiving an indication of a first plurality of precoding vectors, said indication comprising a number of said first plurality of precoding vectors is greater than a preferred rank of transmission, and less than a number of receive antennas of the first secondary station, wherein the first secondary station selects the first plurality of precoding vectors depending on at least one of a correlation between the receive antennas of the first secondary station and a corresponding SINR for each precoding vector;
- and
- control means arranged for selecting a first transmission precoding vector based on a combination of the first precoding vectors.
A system comprising:
- a primary station:
- and
- a secondary station, the secondary station further comprising:
- transmitting means arranged for transmitting to the primary station an indication of a first plurality of precoding vectors, said indication comprising a number of said first plurality of precoding vectors greater than a preferred rank of transmission from the primary station, and less than a number of receive antennas of the first secondary station, wherein the secondary station selects the first plurality of precoding vectors depending on at least one of a correlation between the receive antennas of the secondary station and a corresponding SINR for each precoding vector.
