Methods and apparatus are provided for configuring a plurality of User Equipments (UEs) to communicate with a base station. In one example, a method includes determining, for each UE, a respective bandwidth based on an indication of channel quality between the UE and the base station, and configuring at least a subset of the plurality of UEs to communicate with the base station based on the respective bandwidths.

Configuring a plurality of user equipments

A technique for transmitting on a multiple-input channel from a transmitting device to at least one receiving device is described. As to a method of the technique, a quality of a channel estimate of the multiple-input channel from the transmitting device to the at least one receiving device is determined. A transmission on the multiple-input channel from the transmitting device to the at least one receiving device is performed. The transmission is spatially precoded using at least one precoder determined out of a set of precoders. A size of the set of precoders is an increasing or non-decreasing function of the determined quality of the channel estimate.
