    Abstract: A positioning method, a device, a system, a terminal, an LMF entity, and a medium, used to solve the problem of low positioning accuracy of UE-based OTDOA in the prior art. The method includes a terminal sending to a location management function (LMF) entity an auxiliary positioning data request message includes first identification information of a beam reference signal detected by the terminal itself, receiving from the LMF entity auxiliary positioning data of beam direction information of a beam reference signal including second identification information, and the second identification information is identification information of a beam reference signal sent by a neighboring base station and determined, according to the first identification information, by the LMF entity as being detectable by the terminal, and determining an RSTD of each beam reference signal having the first identification information or the second identification information, and determining position information of the terminal according to the determined RSTD and a beam direction of each beam reference signal.

    Abstract: Disclosed are a method and apparatus for determining an RA-RNTI. In the present application, a base station receives a random access preamble sent by a terminal; the base station determines an RA-RNTI according to a time-frequency resource occupied by the random access preamble, wherein the time-frequency resource is a time-frequency resource of an orthogonal frequency division multiplexing (OFDM) symbol level; and the base station sends a random access response message, wherein the random access response message comprises downlink control information allocated, by the base station, for the terminal, and the downlink control information is scrambled using the RA-RNTI. By means of the present application, an RA-RNTI can be determined during a random access process of an NR system.
