Abstract:
1. A method for signaling a plurality of transmission parameters for a plurality of communications between a primary station and a plurality of respective secondary stations wherein the transmissions to the plurality of secondary stations at least partly overlap in time and frequency and each use a different antenna or combination of antennas for transmission in a multi-user MIMO mode, the method comprising the steps of (a) signaling at least one first transmission parameter in a multicast message addressed to at least two secondary stations, the at least one first transmission parameter representing a resource allocation being common to respective communications corresponding to the at least two secondary stations, and (b) signaling at least one second transmission parameter in a unicast message to selected ones of said at least two secondary stations, each of said unicast messages being addressed to a specific one of said at least two secondary stations, said at least one second transmission being associated with said resource allocation and specific to said specific one of said at least two secondary stations.
