Devices, methods and apparatuses for beam reporting

A network device, comprising:

• at least one processor;
• and
• at least one memory including computer program codes, wherein the at least one memory and the computer program codes are configured to, with the at least one processor, cause the network device to:
• receive capability information on beam prediction from a terminal device, the capability information indicating at least one of:
• an intra-cell beam prediction;
• an inter-cell beam prediction;
• a time domain beam prediction;
• a spatial domain beam prediction;
• and wherein the capability information further indicates at least one of:
• a number of channel state information reference signal resource indication-reference signal received power, CRI-RSRP, which is supported to be contained in a beam report;
• a number of synchronization signal/physical broadcast channel block resource indication-reference signal received power, SSBRI-RSRP, which is supported to be contained in a beam report;
• the maximum number of configured cell identities other than the identity of a serving cell;
• or
• the maximum number of SSB resources configured for measuring Layer 1-RSRP within a slot for at least one of the serving cell or another cell;
• transmit a beam reporting configuration to the terminal device, the beam reporting configuration indicating at least one set of beams for at least one of beam measurements or beam predictions, wherein each beam of the at least one set of beams is associated with a cell of multiple cells which are able to be measured by the terminal device;
• and
• receive, from the terminal device, a reporting of at least one beam associated with the at least one set of beams, wherein the at least one beam comprises a predicted beam which is associated with a cell of the multiple cells.
