If PRACH repetition transmission is introduced to enhance PRACH coverage, then the communication system can transmit multiple PRACH signals, but the method for transmitting these multiple PRACH signals has not been determined, affecting system performance
Solution Approach 1:
The patent applies parameter changes by dynamically adjusting transmission power parameters and selecting from multiple PRACH resource sets based on repetition numbers. The terminal determines parameters including transmission power of single PRACH signal and PRACH resource set according to the specific repetition transmission scenario, enabling adaptive optimization of multiple PRACH signal transmissions while maintaining reliable coverage enhancement.
