Methods And Apparatus For Overlaying Multi-Carrier And Direct Sequence Spread Spectrum Signals In A Broadband Wireless Communication System

Patent No. EP3876490 (titled "Methods And Apparatus For Overlaying Multi-Carrier And Direct Sequence Spread Spectrum Signals In A Broadband Wireless Communication System") was filed by NEO Wireless on Jan 27, 2005. The application was issued on May 17, 2023.

Patent Summary

A communication method for a mobile station operating within a time frame structure (frames comprising subframes, time slots, and OFDM symbols) utilizes a hybrid Multi-Carrier (MC) and Direct Sequence Spread Spectrum (DSSS) approach. The mobile station receives random access channel availability from a base station and transmits a spread spectrum random access signal within an uplink frequency band. This signal contains a base-station-designated sequence, a reserved guard period, and a duration exceeding a multiple of OFDM symbols. Upon receiving an acknowledgement containing a mobile station identifier and power/time adjustments, the mobile station transmits a message in the uplink frequency band utilizing the specified timing and power. The system leverages DSSS for initial access and MC for high-spectral-efficiency broadband data.
