WIRELESS DEVICE, NETWORK NODE, METHODS THEREIN, FOR RESPECTIVELY SENDING AND RECEIVING A REPORT ON QUALITY OF TRANSMITTED BEAMS

摘要

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.

主权项

1. A method performed by a wireless device for sending a report on channel information to a network node, the network node controlling at least one Transmission Point, TP, which at least one TP transmits TP beams, wherein each of at least a number N of the TP beams is associated with one or more respective beamformed Beam-specific Reference Signals, BRS, for channel information measurements, the wireless device and the network node operating in a wireless communications system, the method comprising:
sending the report on the channel information to the network node, the report on the channel information comprising a number of sub-reports, wherein each sub-report is associated with:
one respective TP beam of the N TP beams, which is an associated TP beam, wherein each one associated TP beam comprises at least one BRS of the one or more BRS associated with each of the N TP beams, wherein each one associated TP beam is selected by the wireless device, andat least one indicator of channel quality value, wherein the indicator of channel quality value is for one code word transmitted by the network node on the associated TP beam.
