ANTENNA PORT GROUP INFORMATION REPORTING

Abstract

A communication device (12) transmits, for each of one or more antenna port groups (18-1…18-N) into which antenna ports (16) of the communication device (12) are grouped, information (20-1…20-N) characterizing the antenna port group (18-1…18-N). In some embodiments, the information (20-1…20-N) characterizing the antenna port group (18-1…18-N) includes information indicating into how many columns antenna ports (16) in the antenna port group (18-1…18-N) are arranged and/or information indicating into how many rows antenna ports (16) in the antenna port group (18-1…18-N) are arranged. In other embodiments, the information (20-1…20-N) characterizing the antenna port group (18-1…18-N) alternatively or additionally includes information indicating a maximum oversampling factor supported by the antenna port group (18-1…18-N). In yet other embodiments, the information (20-1…20-N) characterizing the antenna port group (18-1…18-N) alternatively or additionally includes information indicating a coherence capability of the one or more antenna ports (16) included in the antenna port group (18-1…18-N) as being fully coherent and non-coherent.
