Description

This disclosure relates to the field of communications technology, and more specifically, to a repetitive transmission method, a repetitive transmission device, a communications device, and a computer-readable storage medium. To improve communication efficiency, full-duplex communication has been proposed in related technologies. For example, by setting an uplink (UL) subband for the terminal in the downlink (DL) slot, the terminal can transmit information to the network-side device using the uplink subband of the downlink slot, and can also receive information transmitted from the network device using the portion of the downlink slot other than the uplink subband, thereby achieving full-duplex communication. Furthermore, to improve transmission reliability, related technologies propose repetition techniques, which allow the same information to be transmitted repeatedly, and each transmission in repetition can be placed in a different slot. However, since the frequency domain resources are the same for each repetition, problems may arise where not all frequency domain resources are allocated to subbands, or not all are allocated to the active bandwidth portion (BANDWidth Part, BWP). Therefore, the embodiments of this disclosure propose a repetitive transmission method, a repetitive transmission device, a communication device, and a computer-readable storage medium to solve the technical problems of related technologies.
