1. An uplink transmission apparatus, comprising:
a receiver configured to receive indication information used for indicating a terminal equipment to transmit an uplink transmission, the indication information indicating the terminal equipment to transmit the uplink transmission according to an integer parameter, the integer parameter being used for calculating a duration of cyclic prefix extension preceding a first symbol of the uplink transmission; and
processor circuitry configured to, in a case where a value of the integer parameter is not configured or the uplink transmission is for contention-based random access (CBRA), calculate the duration of the cyclic prefix extension according to the value of the integer parameter determined according to timing advance and transmit the cyclic prefix extension and the uplink transmission.
