Example uplink transmission resource requesting methods and apparatus are described. One example method includes a terminal determines that a collision occurs when the terminal sends a first request to a network device, where the first request is used to request the network device to schedule an uplink transmission resource for the terminal. The terminal adjusts a manner of sending the first request according to a preset rule. In embodiments of this application, the terminal may request the uplink transmission resource from the network device by using the first request.
