1. An apparatus for performing multi-user transmission to a plurality of other transmission ends, said apparatus being configured:
to broadcast a request for transmission to said plurality of other transmission ends; to provide said request with a Medium Access Control (MAC) frame which includes a list of at least two identifications of other transmission ends which are requested to reply to said request; and to use said request for transmission as a request for feeding back a channel state information, to assess channel realizations of said other transmission ends based on channel state feedback information received from said other transmission ends, and to derive appropriate beamforming vectors for said other transmission ends, wherein an order of the identifications in the list is used by the other transmission ends to derive a timing corresponding to said order for a response to said request. |
