Abstract: Provided in the present application are a physical downlink control channel detection method and a related apparatus. A terminal device receives indication information sent by a network device side, wherein the indication information may include an association relationship between search space sets, and a specified monitoring mode of the terminal device. The terminal device can determine, on the basis of the indication information, an associated MO which is used for the same PDCCH, such that the terminal device can narrow a blind detection range, thereby effectively reducing the number of times of blind merging of candidate PDCCHs during PDCCH joint detection and decoding. The problem of it being impossible for a terminal device to detect a PDCCH within the scope of a monitoring capability is alleviated, thereby improving the success rate of PDCCH transmission.

Abstract: A method and apparatus for determining an information transmission position. The method includes upon receiving at least one control information DCI sent by a network side, a terminal determines a reference transmission position according to a predefined rule, the preset rule being predefined information or configured by high-layer signaling, and then determines, according to the reference transmission position, a transmission parameter of a first physical channel or first physical information. In this way, a transmission parameter of a first physical channel or first physical information can be determined according to a determined reference transmission position, thus avoiding the problem of a reception failure of transmitted data information or first physical information due to incorrect determination of a transmission position of the first physical channel or first physical information by a terminal, and ensuring the reliability of reception of the transmitted data information by the terminal.
