Process for Beamforming Data to be Transmitted by a Base Station in a MU-MIMO System and Apparatus for Performing the Same |
摘要 |
A process for beamforming data to be transmitted in a MU-MIMO communication system comprising a base station and a selected set of User Equipments (UE) communicating with said base station; said data being precoded by said base station in accordance with a beamforming matrix complying with a precoding matrix under the form of: (formula 1) Where—M is the number of transmit antennas—D is a diagonal unitary matrix of the form D=diag (formula 2)—P is a permutation matrix interchanging only the last M−1 rows. —A is a general Hadamard matrix. and that the signaling information transmitted by the base station to the UE comprises at least a first and a second index which are representative of D, P and A.
