Method for carrier frequency and time offset estimation for mobile communications equipment

A method of performing carrier frequency offset (CFO) estimation and/or time offset (TO) estimation at a radio equipment in a mobile communications system. The method allows, for each of a plurality of synchronization signal (SS) blocks (SSBs) in a SS Burst detected at said radio equipment, determin...

Zusammenfassung:	A method of performing carrier frequency offset (CFO) estimation and/or time offset (TO) estimation at a radio equipment in a mobile communications system. The method allows, for each of a plurality of synchronization signal (SS) blocks (SSBs) in a SS Burst detected at said radio equipment, determining a CFO estimation and/or a TO estimation based on network information signal prediction. The method includes selecting at least some of said detected SSBs in said SSB Burst and combining the CFO estimations and/or the TO estimations to obtain improved CFO compensation and/or TO compensation for signal processing at said radio equipment.
