Claim Text:
1. A primary station comprising: a plurality of antennas configured to transmit signals to a plurality of secondary stations in multicast or unicast multi-user MIMO modes; a transmitter configured to signal messages to a plurality of secondary stations through the plurality of antennas; a controller configured to control the transmitter, and to: signal via a transmitter and a first set of at least one antenna of a plurality of antennas, operating in a multicast mode, an indication of a value of at least one first transmission parameter in a multicast message addressed to at least a first and a second secondary station, the value of the first transmission parameter being for common use for respective communications by both of the first and second secondary stations, signal via the transmitter and a second set of multiple antennas of the plurality of antennas, operating in a unicast multi-user MIMO mode, an indication of a value of at least one second transmission parameter in a unicast message of a plurality of unicast messages to respective first and second secondary stations of the plurality of secondary stations, wherein the signaling of at least two of the unicast messages to different respective secondary stations occurs at least partly mutually overlap in time and frequency, wherein the indication of the value of the at least one first transmission parameter in the multicast message, and the indication of the value of the at least one second transmission parameter in the unicast message are adapted to be combined for computing transmission parameters; and wherein the indication of value of the at least one second transmission parameter provided in the unicast message provided only to the first secondary station is a parameter of the set of signaled transmission parameters for communications between the primary station and the first secondary station.
