PROBLEM TO BE SOLVED: To provide a method of notification of a precoding scheme to accommodate user equipment (UE) having higher Doppler speed.SOLUTION: A different precoding matrix (#0-11) is applied to each OFDM symbol 0-2, 4-9, 11-13 in a transmission stream 301. A downlink control message format is defined to handle assignment of multiple different transmission schemes using the same message format. The downlink control message format includes a control element in one of the message fields along with a set of parameters specifically applicable to the assigned transmission scheme. Based on the value of this control element, the UE sets the specific transmission scheme and determines a set of interpretation rules uniquely associated with that transmission scheme. Using the interpretation rules, the UE reads the set of parameters applied to the selected transmission scheme. |
