Abstract: Embodiments of the present application relates to a method and device for random access, for use in resolving the problem that no current random access process can satisfy requirements of a satellite communication system. The method of the embodiments of the present application comprises: receiving and obtaining a related parameter in a configuration message, the related parameter comprising common cell delay information; generating a physical random access channel random access preamble (PRACH Preamble) sequence, and determining an uplink sending timing location according to the common cell delay information; and sending the PRACH Preamble sequence on a time-frequency resource corresponding to the uplink sending timing location. A relative transmission delay and a multi-path channel delay from a terminal, to a satellite, and to a base station are compensated according to the determined uplink sending timing location, thereby reducing overheads of a PRACH channel.

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 includes 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 location 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 location of the receiving device.
