Transmission resource determination method and apparatus, and storage medium
Embodiments of the present disclosure provide a determining transmission resources method and apparatus, and a storage medium. The method includes receiving first configuration information transmitted by a network side device, and the first configuration information is used for indicating a repetition of a physical downlink control channel (PDCCH); and determining an association between resources used by two or more repetitions of PDCCH or determining the resources used by the two or more repetitions of PDCCH based on one or more of the first configuration information, a first PDCCH association configured by the network side device and a predefined second PDCCH association. The present disclosure can reduce the complexity of blind detection of a terminal device and the number and range of attempts for blind combination.
