Abstract  Abstract

A method, comprising: collecting, by means of a base station (210) in a wireless network, uplink channel quality information of one or more uplink channels of a multi-input, multi-output system, MIMO, employed by the base station (210) to communicate with at least one subscriber station (220, 225) in the wireless network, where the uplink channel quality information is based, at least in part, on the channel quality of channels uplink spatial data and / or data streams, the method being characterized by: calculating, by means of the base station (210), as a function of, at least in part, the uplink channel quality information, downlink, where the downlink channel parameters include the number of downlink channels usable to transmit signals from the base station (210) and a modulation and coding scheme for its use by the base station (210) to transmit signals to the at least one subscriber station (220, 225) through one or more downlink channels of the plurality of downlink channels; and requesting, via the base station (210) from the at least one subscriber station (220, 225), an uplink message that includes feedback information only for the plurality of downlink channels usable to transmit signals from the station. base (210).
