Abstract: Embodiments of the present disclosure relate to methods and apparatuses for updating a repetition level of a downlink channel in a communication network. According to some embodiments, the network device determines a channel quality of a downlink channel based at least in part on uplink transmission from the terminal device to the network device. The network device determines a target channel quality of the downlink channel based on at least one parameter associated with a target performance of the downlink channel. The repetition level indicating the number of repetition transmission in the downlink channel is updated based on the first channel quality and the second channel quality. By employing the above method, the repetition level in the downlink channel may be dynamically updated according to the channel quality of the downlink channel and the target channel quality required by the target performance of the downlink channel, thereby achieving better spectrum efficiency and capacity performance in the communication network.
