Wireless device, network node, methods therein, for respectively sending and receiving a report on quality of transmitted beams
Embodiments herein relate to methods performed by a wireless device for sending a report on channel information to a network node, methods performed by a network node for receiving a report on channel information, and corresponding wireless devices and network nodes. A network node controls at least one Transmission Point (TP) that transmits TP beams. Each TP beam is associated with respective beamformed Beam-specific Reference Signal (BRS) for channel information measurements. The wireless device sends the report, which comprises a number of sub-reports, to the network node. Each sub-report is associated with a TP beam. Each associated TP beam comprises at least one BRS and is selected by the device. Each sub-report is also associated with an indicator of channel quality value for one code word transmitted by the network node on the associated TP beam.
