Communication method, mobile station apparatus and wireless base station apparatus

摘要

In a communication method, a wireless base station apparatus (1-1) periodically sends a reference signal to a mobile station apparatus (1-2, 1-2'); the mobile station apparatus (1-2, 1-2') selects resources to be used for sending communication data to the wireless base station apparatus (1-1) based on a receive time when receiving the reference signal first; the mobile station apparatus (1-2, 1-2') sends information on selected resources to the wireless base station apparatus (1-1), and sends communication data to the wireless base station apparatus (1-1) using the selected resources; the wireless base station apparatus (1-1) receives and demodulates the communication data based on the information on the resources sent from the mobile station apparatus (1-2, 1-2').
