20220376886 · 2022-11-24 · ·

A radio apparatus correlates signal data with stored synchronization data to determine correlation data. The signal data represents a received radio-frequency signal that encodes a data frame, which has a synchronization preamble with a plurality of instances of a predetermined synchronization sequence. The stored synchronization data represents the predetermined synchronization sequence. The radio apparatus identifies a set of peaks in the correlation data, and uses a timing criterion to identify a plurality of subsets of the set of peaks, such that time values of the peaks of each identified subset satisfy the timing criterion. The radio apparatus calculates a correlation score C.sub.j for each of the identified subsets from correlation values of the subset's peaks, and uses the correlation scores C.sub.j to select a subset from the plurality of subsets. Timing or frequency synchronization information for the radio apparatus is determined from the peaks of the selected subset.

The application relates to maintaining time-synchronization of a wireless connection between a network access node and a client device. The wireless connection may be configured for services with latency constraints.
