[0030] In order to better understand the method and apparatus for determining multi-carrier frequency carrier phase positioning capability disclosed by the embodiments of the present disclosure, the following first describes a communication system to which the embodiments of the present disclosure are applied.

[0031] Referring to Fig. 1, Fig. 1 is a schematic diagram of the architecture of a communication system provided by an embodiment of the present disclosure. The communication system may include, but is not limited to, one network side device and one terminal device, where the network side device includes one radio access network device and / or one core network device, and the number and form of devices shown in Fig. 1 are only exemplary and do not limit the embodiment of the present disclosure, and may include two or more network side devices, two or more terminal devices, two or more radio access network devices, and two or more core network devices in practical applications. Take as an example that the communication system shown in Fig. 1 includes one network side device 101 and one terminal device 102, where the network side device 101 includes a radio access network device 1011 and a core network device 1012.

[0032] It should be noted that the technical means of the embodiments of the present disclosure can be applied to various communication systems, such as a long term evolution (LTE) system, a fifth generation (5G) mobile communication system, a 5G new radio (NR) system, or other future new mobile communication systems. It should be noted that the sidelink in the embodiments of the present disclosure is also called a sideline link or a direct communication link.

[0033] Here, the radio access network (RAN) device 1011 is mainly responsible for functions such as radio resource management, quality of service (QoS) management, data compression and encryption on the air interface side. The radio access network device 1011 may include various types of base stations, such as a macro base station, a micro base station (also called a small station), a relay station, an access point, and a transmission reception point (TRP). In systems employing different radio access technologies, the name of a device having a base station function may be different. For example, in a 5th generation (5G) system, it is called gNB, in an LTE system, it is called evolved node B (eNB or eNodeB), and in a 3rd generation (3G) system, it is called node B.

[0034] Optionally, one radio access network device 1011 includes a central unit (CU) and multiple distributed units (DUs), where the CU is a logical node including some gNB functions, and the DU is a logical node including the rest of the gNB functions. One CU can correspond to multiple DUs. In an optional implementation, the CU includes radio resource control (RRC), packet data convergence protocol (PDCP), and Service Data Adaptation Protocol (SDAP) protocol stack functions, and the DU includes radio link layer control protocol (RLC), media access control (MAC), and physical layer (PHY) protocol stack functions. There is a communication interface between the CU and the DU.

[0035] The core network device 1012 is used to provide user connections, manage users, and bear services. For example, the establishment of user connections includes functions such as mobility management (MM) and paging. User management includes user description, QoS, and security (appropriate security measures provided by the authentication center include security management of mobile business and security processing of external network access). Bearer connections include public switched telephone networks (PSTN) to the outside, external circuit data networks and packet data networks, the Internet, and the like. For example, the core network device 1012 may be an Access and Mobility Management Function (AMF) that is mainly responsible for the signaling processing part, i.e., control plane functions including functions such as access control, mobility management, attach / detach, and gateway selection. The core network device 1012 according to the embodiment of the present invention is not limited to the AMF.

[0036] The terminal device 102 in the embodiment of the present disclosure is an entity for receiving or transmitting a user-side signal, such as a mobile phone. The terminal device is also called a terminal, user equipment (UE), mobile station (MS), mobile terminal (MT), etc. The terminal device may be an automobile with a communication function, a smart car, a mobile phone, a wearable device, a tablet (Pad), a personal computer with a wireless transmission and reception function, a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, a wireless terminal device in industrial control, a wireless terminal device in self-driving, a wireless terminal device in remote medical surgery, a wireless terminal device in a smart grid, a wireless terminal device in transportation safety, a wireless terminal device in a smart city, a wireless terminal device in a smart home, etc. The embodiments of the present disclosure are not limited to a specific technology adopted in a terminal device and a specific device form.

[0037] The communication system described in the embodiments of the present disclosure is intended to more clearly explain the technical means of the embodiments of the present disclosure, and is not intended to limit the technical means provided by the embodiments of the present disclosure. It will be understood by those skilled in the art that with the evolution of system architecture and the emergence of new service scenarios, the technical means provided by the embodiments of the present disclosure can be similarly applied to similar technical problems.

[0038] In the related art, a positioning method based on carrier phase has been proposed, in which positioning measurement and reporting are performed based on the fractional part of the carrier phase and the number of revolutions. Here, the fractional part of the carrier phase is a fractional part less than a full revolution, which is a part of the phase difference between a reference signal generated at the receiving side and a carrier signal from a transmitting point that is less than one revolution, or a part of the phase of a carrier signal received at the receiving side from a transmitting point that is less than one revolution. The number of revolutions corresponds exactly to the number of full revolutions excluding the fractional part less than one revolution. Since the number of revolutions of the carrier phase has a fuzzy problem, there is a large room for improvement in the accuracy of positioning measurement.

[0039] In the present disclosure, in order to solve the problem of full-circle fuzziness, multi-carrier frequencies are introduced into NR (New Radio access technology). Multiple carrier frequencies are used to transmit positioning signals, and although the wavelengths of the multiple carrier frequencies are different, the transmission distance experienced is the same, which can well solve the problem of full-circle fuzziness. However, whether a terminal device supports the transmission of multi-carrier frequency positioning signals and which combination of multi-carrier frequency positioning signals it supports needs to be reported by the termination, and currently there is a lack of a method for reporting the relevant terminal device capabilities.

[0040] Based on this, the embodiments of the present disclosure provide a method and apparatus for determining multi-carrier frequency carrier phase positioning capability, so as to at least solve the problems existing in the related art.

[0045] On this basis, the terminal device and the network side device can determine, based on the positioning capability information sent from the terminal device to the network side device, that the terminal device has capability information for transmitting multi-carrier frequency positioning signals, and transmit, receive and measure positioning signals at the multi-carrier frequencies supported by the terminal device, thereby increasing the flexibility of the terminal device and improving the accuracy of positioning measurement.

[0046] Here, the positioning signals are transmitted, received and measured at at least two carrier frequencies, and the at least two carrier frequencies are used to transmit the same positioning signal by aggregating them or to transmit different positioning signals individually. When transmitting the same positioning signal by aggregating them, it is necessary to measure the positioning signals at at least two carrier frequencies to obtain one measurement result, and when transmitting different positioning signals individually, it is necessary to separately measure the positioning signals at one carrier frequency to obtain one measurement result.
