Timing Error Group Indexing for 5G Positioning Accuracy

The patent applies preliminary action by pre-calibrating the timing delays in the receive and transmit signal paths before positioning measurements are performed. The baseband processor determines calibration values for Rx and Tx timing errors based on known reference signals, storing these values for subsequent compensation during actual positioning operations. This advance preparation eliminates timing delays that would otherwise reduce positioning accuracy.

The patent implements feedback mechanisms where the baseband processor continuously monitors timing errors in receive and transmit paths, compares them against calibration values, and adjusts compensation parameters accordingly. The system reports timing error group indices and positioning measurements back to the network, enabling iterative refinement of timing compensation to maintain high positioning accuracy.

The patent segments the timing error compensation into distinct, manageable components: receive timing error calibration, transmit timing error calibration, and combined Rx/Tx timing error calibration. Each component is handled separately through dedicated calibration procedures and compensation mechanisms, making the overall complex system more tractable and maintainable while achieving high positioning accuracy.

The patent changes parameters by introducing timing error group (TEG) indices that categorize different timing error conditions. Instead of continuously adjusting numerous timing parameters, the system uses discrete TEG index values to represent timing error states, simplifying the compensation process while maintaining accuracy. The baseband processor selects appropriate compensation values based on the determined TEG index.
