AI Technical Summary
In existing technologies, when base stations identify preamble sequences using correlation peak detection methods based on signal energy, they are prone to misjudging noise and interference as valid preambles, leading to a high false alarm rate in physical random access channels, reduced network access performance, and decreased system capacity and throughput.
After detecting the preamble sequence, the system receives uplink physical channel data using the second uplink transmission resource, performs CRC checksum verification and index value comparison, verifies the validity of the preamble sequence, and reduces the probability of false alarms.
Effectively filtering out false detections caused by noise and interference reduces the false alarm probability of physical random access channels, avoids wasting ineffective resources, and improves terminal access reliability and network performance.
