摘要： Disclosed in embodiments of the present application are a method and device for scheduling transmission, which are used to solve the problem in which there are currently no solutions for transmission scheduling that supports various communication scenario changes. In the embodiments of the present application, a network side device sends a transmission instruction to a terminal device; and the terminal device determines a transmission scheduling mode according to the transmission instruction and performs transmission scheduling. Moreover, after determining that an adjustment condition is satisfied, the network side device determines a new transmission scheduling mode and notifies the terminal device, so that the terminal device performs transmission scheduling by means of the new transmission scheduling mode. In the described method, the network side device may adjust the transmission scheduling mode after determining that the current transmission scheduling mode satisfies the adjustment condition, and then notify the terminal device, so that the terminal device adjusts the transmission scheduling mode, which better ensures the transmission performance and reliability of a system, and achieves dynamic switching between multiple transmission modes.

摘要： 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.
