Abstract: Disclosed in embodiments of the present application are a resource allocation method, a device, and a medium. The method comprises: a terminal device determines N NPRACH transmission resources corresponding to a sending period of an ephemeris-bearing SIB bearing according to said sending period as well as configuration information for an NPRACH transmission resource indicated in an SIB2, where N is a natural number greater than zero; the terminal device randomly selects one NPRACH transmission resource from among the N NPRACH transmission resources; and the terminal device performs random access on a network device by means of the selected NPRACH transmission resource. By means of the present method, a terminal can randomly select one transmission resource to perform random access from among a plurality of available transmission resources, causing randomly delayed sending when the terminal performs random access, allowing for dispersion among different transmission resources, the probability of a collision is lowered, and the problem of random access failure caused by a transmission resource sending collision due to terminals initiating random access on a same transmission resource is effectively prevented.

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.
