METHODS FOR RECEIVING AND SENDING A REPORT COMPRISING CHANNEL STATE INFORMATION

摘要

Embodiments herein relate to a network node and method performed by a network node (211, 230) for controlling one or more Transmission Points (TPs) which transmit TP beams. The network node selects a set of TP beams based on at least one of: one or more measurements by the wireless device on first beam-specific reference signals of the TP beams and a measured transmission from the wireless device. Each beam in a TP uses one unique signal. The network node configures the wireless device (250) with a set of second beam-specific reference signals. Each second beam-specific signal is associated with a selected TP beam. The node receives a report from the wireless device, comprising channel state information for at least a subset of the selected set of TP beams, measured on the set of second beam-specific signals which are mutually orthogonal. The embodiments also relate to a wireless device (250) and a method therein.
