Abstract: Provided in embodiments of the present invention are a method and device for transmitting control information. In an embodiment of the present invention, the method comprises: a base station determining to repeatedly transmit DCI; and the base station repeatedly causing the DCI to be carried on at least two PDCCHs used for repeated DCI transmission, and transmitting same. When a terminal is unable to successfully detect some of PDCCHs for repeated DCI transmission due to a blockage or interference, the terminal can still perform detection on the remaining PDCCHs to obtain DCI, thereby enhancing the reliability of DCI transmission.

Abstract: 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.

Abstract: A positioning method and device used for solving the problems of the existing method for determining an integer ambiguity being relatively difficult and relatively time-consuming. During positioning, the method comprises: a receiving device determining a virtual phase measured value according to at least two received C-PRS signals (600); determining a TOA measured value according to a received PRS signal (601); determining a virtual integer ambiguity according to the TOA measured value and the virtual phase measured value (602); and finally, determining the position of the receiving device according to the virtual integer ambiguity (603). An integer ambiguity search space is reduced, and the integer ambiguity is determined faster, thus improving the efficiency of determining the position of the receiving device.
