Embodiments of the present disclosure relate to communication. According to embodiments of the present disclosure, a network device is able to configure resources dedicated to repetition of transmission during the access procedure. If a terminal device determines to perform the repetition of transmission, the terminal device uses the dedicated resources for the transmission. The numbers of the repetition are determined based on a target power for the transmission and a maximum power at the terminal device. In this way, it improves coverage of the terminal device and the success in accessing channel.
