Abstract:
A high-accuracy positioning method and a corresponding positioning system and positioning terminal are provided, and may be used in the field of intelligent vehicle technologies. In this positioning method, a real-time kinematics (RTK) positioning technology and a multi-receiver constraint MRC positioning technology are used to determine a location of a to-be-positioned target. In this positioning method, an RTK error correction model and an MRC error correction model may be preconstructed according to a big data technology. The RTK error correction model is used to provide a correction value for an original detection value obtained based on the RTK positioning technology. The MRC error correction model is used to provide a correction value for an original detection value obtained based on the MRC positioning technology. Then, the correction values are used to calculate the location of the to-be-positioned target.

Abstract:
A resource allocation method to resolve a problem that a transport block of a typical enhanced voice service (EVS) scenario in an air interface is much smaller than a transport block of a conventional adaptive multi rate (AMR), and use of a resource allocation method in the existing long term evolution (LTE) causes a waste of user spectrum resources such that spectrum utilization in an EVS scenario can be improved. The method includes determining resource allocation information and resource allocation block indication information, where the resource allocation information includes information indicating at least one fractional resource block (FRB) allocated to user equipment, and the resource allocation block indication information indicates that a resource allocation block is the FRB, where a resource occupied by the FRB is less than one RB, and notifying the user equipment of the resource allocation information and the resource allocation block indication information.
