The method comprises: a UE determines a target reporting mode for beam failure of a first SCell; if the UE detects that beam failure occurs to the first SCell, the UE reports information of beam failure recovery to a base station by using the target reporting mode; the base station performs beam failure recovery of the first SCell according to the detected information indicating that a beam failure event occurs to the first SCell and/or candidate beam information. According to the present application, a UE may perform beam failure reporting of a SCell in a relatively reliable mode or a relatively reliable mode selected by a base station, so that the system is able to use a reliable beam reporting mode of the SCell to perform beam failure recovery of the SCell.

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.
