METHODS AND SYSTEMS FOR EMBEDDING SUPPLEMENTARY DATA CHANNEL IN LTE-BASED COMMUNICATION SYSTEMS

摘要

Disclosed herein are methods and systems for embedding a supplementary data channel in LTE-based communication systems. One embodiment takes the form of a process that includes obtaining a primary data signal. The primary data signal includes a given symbol, and the given symbol includes primary payload data prepended with a given cyclic prefix. The process also includes obtaining supplementary payload data. The process also includes generating a modified primary data signal at least in part by replacing an initial portion of the given cyclic prefix with a subset of the supplementary payload data. The process also includes outputting the generated modified primary data signal for transmission via an air interface.
