Data transmission method using dual protocol preambles
The patent US12047998B2 outlines methods and systems for data transmission and reception in mobile access networks that utilize two different communication protocols. The primary method involves encoding data according to a first protocol and generating a preamble that conforms to both the first and a second protocol. This preamble includes fields that facilitate synchronization and detection, allowing for effective communication in a shared frequency band. The process includes adding a preamble field from the first protocol to the preamble of the second protocol, resulting in a new preamble that is then combined with the encoded data to form a complete frame for transmission.
Additionally, the patent describes a method for receiving data frames that incorporates the detection of the new preamble and the encoded data. The receiving equipment compares the detected preamble against stored fields to estimate the frame's temporal duration and decode the data accordingly. The system also allows for adjustments in energy thresholds based on the recognition of the preamble, enhancing the reliability of data reception. The patent further details the architecture of mobile terminals capable of both transmitting and receiving data, emphasizing the integration of encoders, processors, and detectors to facilitate these processes in a shared frequency environment.
