A method of wireless communication between a base station (110, 610) and at least one user equipment, UE (120, 633), the method comprising: a first precoder configuration step, comprising: transmitting first reference signals from the base station (110, 610) to the at least one UE (120, 633) by using a first set of antenna ports of the base station (110, 610); generating, by the at least one UE (120, 633), first feedback information associated with the first reference signals; transmitting the first feedback information from the at least one UE (120, 633) to the base station (110, 610); configuring, by the base station (110, 610), a first precoder based on the first feedback information; classifying, by the base station (110, 610), the at least one UE (120, 633) based on the first feedback information; allocating, by the base station (110, 610), resources to the at least one UE (120, 633) based on the classification of the at least one UE (120, 633); and a second precoder configuration step, comprising: transmitting second reference signals from the base station (110, 610) to the at least one UE (120, 633) on the allocated resources based on the configuration of the first precoder; generating, by the at least one UE (120, 633), second feedback information associated with the second reference signals; transmitting the second feedback information from the at least one UE (120, 633) to the base station (110, 610); and configuring a second precoder based on the second feedback information. a first precoder configuration step, comprising: transmitting first reference signals from the base station (110, 610) to the at least one UE (120, 633) by using a first set of antenna ports of the base station (110, 610); generating, by the at least one UE (120, 633), first feedback information associated with the first reference signals; transmitting the first feedback information from the at least one UE (120, 633) to the base station (110, 610); configuring, by the base station (110, 610), a first precoder based on the first feedback information; classifying, by the base station (110, 610), the at least one UE (120, 633) based on the first feedback information; allocating, by the base station (110, 610), resources to the at least one UE (120, 633) based on the classification of the at least one UE (120, 633); and transmitting first reference signals from the base station (110, 610) to the at least one UE (120, 633) by using a first set of antenna ports of the base station (110, 610); generating, by the at least one UE (120, 633), first feedback information associated with the first reference signals; transmitting the first feedback information from the at least one UE (120, 633) to the base station (110, 610); configuring, by the base station (110, 610), a first precoder based on the first feedback information; classifying, by the base station (110, 610), the at least one UE (120, 633) based on the first feedback information; allocating, by the base station (110, 610), resources to the at least one UE (120, 633) based on the classification of the at least one UE (120, 633); and a second precoder configuration step, comprising: transmitting second reference signals from the base station (110, 610) to the at least one UE (120, 633) on the allocated resources based on the configuration of the first precoder; generating, by the at least one UE (120, 633), second feedback information associated with the second reference signals; transmitting the second feedback information from the at least one UE (120, 633) to the base station (110, 610); and configuring a second precoder based on the second feedback information. transmitting second reference signals from the base station (110, 610) to the at least one UE (120, 633) on the allocated resources based on the configuration of the first precoder; generating, by the at least one UE (120, 633), second feedback information associated with the second reference signals; transmitting the second feedback information from the at least one UE (120, 633) to the base station (110, 610); and configuring a second precoder based on the second feedback information.
