The radio access network (RAN) device 1011 is mainly responsible for radio resource management, quality of service (QoS) management, data compression, encryption and other functions on an air interface side. The access network device 1011 may include various forms of base stations, such as a macro base station, a micro base station (also called a small station), a relay station, an access point, a transmission reception point (TRP), etc. In systems using different wireless access technologies, names of devices with a base station function may vary. For example, in a 5th generation (5G) system, it is called gNB; in a LTE system, it is called evolved node B (eNB or eNodeB); and in a 3rd generation (3G) system, it is called node B, etc.
In an embodiment, the access network device 1011 includes a central unit (CU) and a plurality of distributed units (DU). The CU is a logic node, and includes a part of functions of the gNB; and the DU is a logic node, and includes functions of the gNB other than those of the CU. One CU may correspond to a plurality of DUs. In an implementation, the CU includes radio resource control (RRC), packet data convergence protocol (PDCP), and service data adaptation protocol (SDAP) stack functions.

The core network device 1012 of the embodiments of the present disclosure is not limited to the AMF.
The terminal 102 in the embodiments of the present disclosure is an entity on a user side for receiving or transmitting a signal, such as a mobile phone. The terminal may also be called a terminal, a user equipment (UE), a mobile station (MS), a mobile terminal (MT), etc. The terminal may be a vehicle with a communication function, an intelligent vehicle, a mobile phone, a wearable device, a Pad, a computer with a wireless transceiver function, a virtual reality (VR) terminal, an augmented reality (AR) terminal, a wireless terminal in industrial control, a wireless terminal in self-driving, a wireless terminal in remote medical surgery, a wireless terminal in a smart grid, a wireless terminal in transportation safety, a wireless terminal in a smart city, a wireless terminal in a smart home, etc. The embodiments of the present disclosure do not limit a specific technology and a specific shape used by the terminals.
It is to be understood that the communication system described in the embodiment of the present disclosure is to clarify the technical solutions of the embodiments of the present disclosure more clearly, and does not constitute a limitation to the technical solutions provided by the embodiments of the present disclosure. It could be known to those of ordinary skill in the art that with the evolution of a system architecture and the emergence of a new business scenario, the technical solutions provided by the embodiments of the present disclosure is also applicable to similar technical problems.
In related art, there is provided a carrier phase-based positioning method, and positioning measurement and reporting are performed according to a fractional part and an integer number of complete cycles of the carrier phase. The fractional part of the carrier phase refers to a fractional part smaller than one complete cycle, and is a part of a phase difference between a reference signal generated by a receiver and a carrier signal from a sender which is smaller than one complete cycle, or a part of a phase of the carrier signal received by the receiver from the sender which is smaller than one complete cycle. The integer number of complete cycles corresponds to an exact integer number of the complete cycles other than the fractional part smaller than complete cycle. Due to the integer ambiguity problem of the carrier phase, there is still much room for improvement in accuracy of positioning measurement.
In the invention of the present disclosure, in order to solve the integer ambiguity problem, a multi-carrier-frequency is introduced into a new radio access technology (NR). The multiple carrier frequencies are used to send positioning signals, and the multiple carrier frequencies have different wavelengths but experience a same transmission distance, which can better solve the integer ambiguity problem. However, the terminal needs to report whether a terminal supports transmission of multi-carrier-frequency positioning signals and which combination of multi-carrier-frequency positioning signals is supported by the terminal for transmission. At present, there is still a lack of a relevant method for reporting a capacity of the terminal.
Based on this, embodiments of the present disclosure provide a method and an apparatus for determining a multi-carrier-frequency carrier phase positioning capability, so as to at least solve the problems in the related art.
