Method for operating a secondary station

A primary station communicating in a multiple-input-multiple-output (MIMO) wireless transmission system, with at least one secondary station, the primary station comprising:

• a plurality of transmit antennas,
• a transmitter coupled to the plurality of transmit antennas,
• a plurality of receive antennas,
• a receiver, coupled to a plurality of receive antennas,
• a controller connected to the transmitter and receiver, configured to receive from the secondary station a single precoding indicator representative of at least one set of recommended precoding coefficients, wherein the same single precoding indicator applies for a plurality of available transmission modes, and
• the controller being configured for selecting a transmission mode out of the plurality of available transmission mode based at least partly on the single precoding indicator.

A secondary station communicating in a multiple-input-multiple-output (MIMO) wireless transmission system, with a primary station, the secondary station comprising:

• a plurality of receive antennas,
• a receiver coupled to the plurality of receive antennas,
• a plurality of transmit antennas,
• a transmitter, coupled to the plurality of transmit antennas, configured to transmit a single precoding indicator representative of at least one set of recommended precoding coefficients to the primary station, wherein the same single precoding indicator applies for a plurality of available transmission modes.

A tangible computer-readable storage medium that is not a transitory propagating signal or wave, encoded with control information including instructions, for controlling a primary station for performing a method for communication in a multiple-input-multiple-output (MIMO) wireless transmission system, with at least one secondary station, the method comprising:

• at the primary station:
• receiving in a transceiver of the primary station, from the secondary station, a single precoding indicator representative of at least one set of recommended precoding coefficients, wherein the same single precoding indicator applies for a plurality of available transmission modes;
• and
• selecting in a controller, a transmission mode out of the plurality of available transmission modes based at least partly on the single precoding indicator.

A method for operating a primary station, for communication in a multiple-input-multiple-output (MIMO) wireless transmission system, with at least one secondary station, the method comprising:

• in the primary station:
• a receiver, receiving from the secondary station a single precoding indicator representative of at least one set of recommended precoding coefficients, wherein the same single precoding indicator applies for a plurality of available transmission modes;
• and
• a controller selecting a transmission mode out of the plurality of available transmission mode based at least partly on the single precoding indicator.
