<p>The invention relates to a method of providing a broadcast or multicast service to user equipments (UEs, 114; 116; 118; 120) in a digital wireless telecommunication network, the digital wireless telecommunication network comprising a set of antennas (102; 104) for providing the service to the user equipments (114; 116; 118; 120), the method comprising:
- sending broadcast or multicast service data to the user equipments (114; 116; 118; 120),
- receiving feedbacks from the user equipments (114; 116; 118; 120) in response to the sent data, the feedbacks comprising user equipment service data reception quality information and/or a precoding vector information, wherein the precoding vector information indicates for each of the user equipments (114; 116; 118; 120) a precoding vector for reception of the broadcast or multicast service,
- determining an optimized precoding vector for transmitting the service to the user equipments (114; 116; 118; 120), wherein the determination of the optimized precoding vector is performed by analyzing the feedbacks.</p> |
