[0037] The technical solution in this application will be described below with reference to the accompanying drawings.

[0038] FIG1 illustrates a wireless communication system 100 used in an embodiment of the present application. The wireless communication system 100 may include a network device 110 and a user equipment (UE) 120. The network device 110 may communicate with the UE 120. The network device 110 may provide communication coverage for a specific geographic area and may communicate with the UE 120 within the coverage area. The UE 120 may access a network (e.g., a wireless network) through the network device 110.

Optionally, the wireless communication system 100 may include multiple network devices, and each network device may include a different number of terminal devices within its coverage area, which is not limited in this embodiment of the present application. Optionally, the wireless communication system 100 may also include other network entities such as a network controller and a mobility management entity, which is not limited in this embodiment of the present application.

[0041] The UE in the embodiments of the present application may also be referred to as a terminal device, an access terminal, a user unit, a user station, a mobile station, a mobile station (MS), a mobile terminal (MT), a remote station, a remote terminal, a mobile device, a user terminal, a terminal, a wireless communication device, a user agent, or a user apparatus. The UE in the embodiments of the present application may refer to a device that provides voice and / or data connectivity to a user and can be used to connect people, objects, and machines, such as a handheld device or an in-vehicle device with wireless connection capabilities. The UE in the embodiments of the present application can be a mobile phone, a tablet computer, a laptop computer, a PDA, a mobile internet device (MID), a wearable device, a virtual reality (VR) device, an augmented reality (AR) device, 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. Optionally, the UE can be used to act as a base station. For example, the UE can act as a scheduling entity that provides sidelink signals between UEs in V2X or D2D, etc. For example, a cellular phone and a car communicate with each other using sidelink signals. The cellular phone and smart home devices communicate without relaying the communication signal through a base station.

[0042] The network device in the embodiments of the present application may be a device for communicating with a UE, and may also be referred to as an access network device or a radio access network device. For example, the network device may be a base station. The network device in the embodiments of the present application may refer to a radio access network (RAN) node (or device) that connects a UE to a wireless network. A base station may broadly cover various names as follows, or be replaced with the following names, such as: NodeB, evolved NodeB (eNB), next generation NodeB (gNB), relay station, access point, transmitting and receiving point (TRP), transmitting point (TP), master station MeNB, secondary station SeNB, multi-standard radio (MSR) node, home base station, network controller, access node, wireless node, access point (AP), transmission node, transceiver node, baseband unit (BBU), remote radio unit (RRU), active antenna unit (AAU), remote radio head (RRH), central unit (CU), distributed unit (DU), positioning node, etc. A base station may be a macro base station, a micro base station, a relay node, a donor node, or the like, or a combination thereof.

[0043] In some embodiments, the network device can be fixed or mobile. For example, a helicopter or drone can be configured to act as a mobile network device, and one or more cells can move according to the location of the mobile network device. In other examples, the helicopter or drone can be configured to act as a device for communicating with another network device. In some embodiments, the network device can refer to a CU or a DU, or the network device can include a CU and a DU, or the network device can also include an AAU.

[0044] It should be understood that network devices can be deployed on land, including indoors or outdoors, handheld or vehicle-mounted; can also be deployed on water; and can also be deployed in the air on aircraft, balloons, and satellites. The embodiments of this application do not limit the network devices and the scenarios in which they are used.

[0045] It should also be understood that all or part of the functions of the network device and UE in this application can also be implemented through software functions running on hardware, or through virtualization functions instantiated on a platform (such as a cloud platform).

[0046] With the development of communication technology, some communication systems support location services (LCS), which can locate terminal devices. Several common positioning methods are introduced below.

[0047] Time difference of arrival (TDOA) positioning is a positioning method that uses time difference. TDOA positioning includes uplink and downlink positioning. When using uplink positioning, the terminal device transmits an uplink sounding reference signal (SRS). Each base station needs to measure the SRS sent by the terminal device to determine the path difference between the terminal device and the signals from different base stations. The intersection of more than two unrelated path differences forms the intersection point of a hyperbola, and the resulting intersection point is the positioning result (the terminal device's location). When using downlink positioning, each base station transmits a downlink positioning reference signal (DL-PRS). The terminal device needs to measure the reference signal sent by each base station to determine the path difference between the terminal device and the signals from different base stations. The intersection of more than two unrelated path differences forms the intersection point of a hyperbola, and the resulting intersection point is the positioning result. TDOA positioning requires that the base stations involved in positioning are time synchronized. If the two base stations are not time-synchronized, the calculation result of the signal path difference between the terminal device and the two base stations will contain a value that is proportional to the degree of time asynchrony between the two base stations, which will cause deviation in the positioning results.

[0048] For example, as shown in Figure 2, the distance between the UE and TRP4 is d4, the distance between the UE and TRP3 is d3, the distance between the UE and TRP2 is d2, and the distance between the UE and TRP1 is d1. d4 and d1 correspond to hyperbola S4 (the distance difference from points on hyperbola S4 to d4 and d1 is equal), d4 and d3 correspond to hyperbola S3 (the distance difference from points on hyperbola S3 to d4 and d3 is equal), d3 and d2 correspond to hyperbola S2 (the distance difference from points on hyperbola S2 to d3 and d2 is equal), and d2 and d1 correspond to hyperbola S1 (the distance difference from points on hyperbola S1 to d2 and d1 is equal). As can be seen from the figure, the intersection of the hyperbolas is the location of the terminal device, and d1, d2, d3, and d4 are positive numbers. Generally, at least two hyperbolas, or three TRPs, are required to locate the terminal device.

[0049] Round trip time (RTT) positioning is a positioning method that uses the round-trip time of a signal. RTT positioning uses reference signals transmitted between a terminal device and a base station to estimate the distance, and then determines the position based on the distance between the terminal device and at least three base stations.

[0050] For example, as shown in Figure 3, the UE sends an SRS to the RAN and receives a DL-PRS sent by the RAN. At the same time, the UE records the duration from when it sends the SRS to when it receives the DL-PRS, and the RAN records the duration from when it receives the SRS to when it sends the DL-PRS. Then, the signal propagation time T between the UE and the RAN is:

[0051] T=(T UE -T RAN ) / 2

[0052] Among them, T UE Indicates the duration from when the UE sends SRS to when it receives DL-PRS, T RAN Indicates the duration from when the RAN receives the SRS to when the RAN sends the DL-PRS.

[0053] Furthermore, the distance between the UE and the RAN can be calculated based on the signal propagation time T between the UE and the RAN. After the distances between the terminal device and at least three base stations are calculated, the location of the terminal device can be estimated.

[0054] In actual positioning scenarios (for example, in cities), the communication link between the terminal device and the base station is often non-line of sight (NLOS), that is, the communication link will block the signal. After research, the applicant found that the signal will be greatly attenuated due to the blockage, which will affect the accuracy of the ranging and angle measurement that positioning relies on, thereby reducing the positioning accuracy of the terminal device.

[0055] The intelligent reflecting surface (IRS) is a revolutionary new technology that can significantly improve the performance of wireless communication networks by integrating a large number of low-cost passive reflective elements on a plane, intelligently reconfiguring the wireless propagation environment. Specifically, the different elements of an IRS can independently reflect the incident signal by controlling their amplitude and / or phase, thereby collaboratively achieving sophisticated three-dimensional (3D) passive beamforming for directional signal enhancement or nulling. In stark contrast to existing transmitter / receiver radio link adaptation technologies, the IRS actively modifies the wireless channel between them through highly controllable and intelligent signal reflection. As shown in Figure 4, the RAN can transmit signals to the UE through the intelligent reflecting surface, which can adjust its integrated reflective elements to ensure that the communication link between the intelligent reflecting surface and the terminal device is line of sight (LOS). This provides new degrees of freedom for further improving the performance of wireless links and paves the way for the realization of intelligent and programmable wireless environments. By properly adjusting the 3D passive beamforming, the signal reflected by the IRS can be constructively added with the signals from other paths to enhance the desired signal power at the receiver, or destructively cancel unwanted signals such as co-channel interference. Because the IRS eliminates the use of transmit radio frequency (RF) chains and operates only over short distances, it can be densely deployed with scalable cost and low energy consumption without the need for complex interference management between passive IRSs.

[0056] After analysis, the applicant concluded that if a smart reflective plane is introduced, the signal transmission path can be changed by adjusting the smart reflective plane, so that the communication link between the smart reflective plane and the terminal device is line of sight (LOS) (i.e., unobstructed). This can improve the accuracy of the distance and angle measurements that positioning relies on, thereby improving the positioning accuracy of the terminal device. However, it is currently unclear how to use the smart reflective plane for positioning.

[0057] In order to solve one or more of the above technical problems, the present application proposes a communication method and a communication device, which can use an intelligent reflective plane for positioning, thereby helping to improve the positioning accuracy of terminal equipment.

[0058] The embodiment of the present application is described in detail below with reference to FIG5 .

[0059] FIG5 is a schematic flow chart of a communication method according to an embodiment of the present application. The method 500 shown in FIG5 may include steps S510 and S540, which are as follows:

[0060] S510: The second device sends first information to the first device.

[0061] The first device may be a location management function (LMF) or a terminal device.

[0062] The second device can be a first intelligent reflective plane or a first access network device. The first access network device can transmit signals to the terminal device via the first intelligent reflective plane. Optionally, the communication link between the terminal device and the first intelligent reflective plane can be line-of-sight. In this way, the communication link between the terminal device and the first intelligent reflective plane does not block the signal, allowing accurate ranging and angle measurement information required for positioning to be obtained, thereby improving the positioning accuracy of the terminal device.

[0063] Optionally, the first access network device may obtain location information of the first intelligent reflecting plane. For example, the first intelligent reflecting plane may send the location information to the first access network device, or the location information of the first intelligent reflecting plane may be pre-configured in the first access network device.

[0064] The first information may include location information and signal processing delay information of the first intelligent reflecting plane. Optionally, the location information and signal processing delay information may be sent simultaneously or at different times (in which case the first information may be considered to include multiple pieces of information). For example, the first device may receive location information sent by the first intelligent reflecting plane (or the first access network device), and may also receive signal processing delay information sent by the first access network device (or the first intelligent reflecting plane).

[0065] Optionally, the signal processing delay information may include the duration from when the first intelligent reflective plane receives the signal to when the first intelligent reflective plane reflects (or transmits) the signal. For example, if the time when the first intelligent reflective plane receives the signal is T1 and the time when the first intelligent reflective plane reflects (or transmits) the signal is T2, the signal processing delay information may include T2-T1, where T2 and T1 are positive numbers.

[0066] The signal processing delay information may include the immediate delay or non-immediate delay of signal processing performed by the first intelligent reflective plane. The immediate delay may indicate that the signal processing delay performed by the first intelligent reflective plane is variable, and the first intelligent reflective plane may determine the delay (for signal processing) in real time or periodically. The non-immediate delay may indicate that the signal processing delay performed by the first intelligent reflective plane is constant, and the delay (for signal processing) may be pre-configured in the first intelligent reflective plane. Optionally, the first intelligent reflective plane may send the signal processing delay information to the first access network device.

[0067] The first information is carried in New Radio NR Positioning Protocol A (NRPPa) signaling. Optionally, the NRPPa signaling may include NRPPa ProvideAssistanceData signaling. For example, the second device may send the first information to the first device via NRPPa ProvideAssistanceData signaling.

[0068] In some embodiments, the second device may send the first information upon receiving the trigger request. For example, before S510, the method 500 may include S520, which is as follows:

[0069] S520: The first device sends second information to the second device. Optionally, the second information can be used to request the first information.

[0070] Accordingly, upon receiving the second information, the second device may send the first information to the first device.

[0071] In some embodiments, the second device may directly send the first information to the first device without triggering a request.

[0072] In some embodiments, the second device may indicate to the first device that “the signal is processed by the smart reflective plane.” For example, method 500 may include S530, specifically as follows:

[0073] S530: The second device sends third information to the first device. Optionally, the third information may be used to indicate that the signal transmitted between the first access network device and the terminal device is processed (or reflected) by the intelligent reflection plane.

[0074] For example, for a positioning method based on DL-PRS or a positioning method based on UL-PRS, the second device may send the third information to the first device. For another example, for TDOA positioning or RTT positioning, the second device may send the third information to the first device.

[0075] Optionally, the second device may send the third information to the first device through radio resource control (RRC) signaling and a medium access control control element (MAC CE).

[0076] It should be noted that the embodiment of the present application does not limit the order in which the first information, the second information, and the third information are sent.

[0077] Typically, the location of the smart reflective plane is a known condition for the network. Therefore, as shown in FIG6 , in the communication link from the access network device (e.g., a base station) to the smart reflective plane and then to the terminal device, the path length d1 from the access network device to the smart reflective plane is known (derivable from the position coordinates of the access network device and the smart reflective plane). Furthermore, a signal may introduce a certain delay τ when reflected by the smart reflective plane. Therefore, the distance d2 of the communication link from the smart reflective plane to the terminal device can be derived from the signal measurement results d, d1, and τ of the terminal device (downlink) or the access network device (uplink), i.e., d2 = d - d1 - τ. Because signal transmission between the terminal and the smart reflective surface can be line-of-sight (as shown in FIG6 , the communication link between the access network device and the terminal device is obstructed), the embodiment described in S540 below can locate the terminal device based on d2 (i.e., the first distance information between the terminal device and the first smart reflective plane determined by the first information).

[0078] S540: The first device determines a positioning result of the terminal device according to the first information.

[0079] The positioning result of the terminal device may refer to the location of the terminal device, etc.

[0080] In some embodiments, in S540, the first device may determine first distance information between the terminal device and the first intelligent reflective plane based on the first information; further, the first device may determine a positioning result of the terminal device based on the first distance information.

[0081] The first device may determine the positioning result of the terminal device based on the distance between the terminal device and the multiple smart reflective planes. Optionally, the first device may determine the positioning result of the terminal device based on the first distance information and the second distance information. For example, the first device may determine the positioning result of the terminal device based on the positioning method shown in Figure 2 or Figure 3 based on the first distance information and the second distance information. The second distance information may include N distance information between the terminal device and N second smart reflective planes, where N is an integer greater than or equal to 2.

[0082] In some embodiments, the first device can calculate the distance between the terminal device and the first intelligent reflection plane (i.e., the first distance information) based on the SRS measurement result (such as reported by the first access network device), the distance information between the first access network device and the first intelligent reflection plane, and the signal processing delay information of the first intelligent reflection plane. Optionally, the first device can determine the third distance information between the first access network device and the first intelligent reflection plane based on the position information of the first intelligent reflection plane; further, the first device can determine the first distance information based on the first measurement result of the SRS, the third distance information, and the signal processing delay information. Optionally, the first measurement result can be the measurement result of the SRS transmitted through the first intelligent reflection plane.

[0083] Optionally, the first device may receive the first measurement result sent by the first access network device.

[0084] In some embodiments, the first device can calculate the distance between the terminal device and the second intelligent reflection plane based on the SRS measurement result (such as reported by the second access network device), the distance information between the second access network device and the second intelligent reflection plane, and the signal processing delay information of the second intelligent reflection plane. Optionally, the first device can determine the fourth distance information between the second access network device and the second intelligent reflection plane based on the position information of the second intelligent reflection plane; further, the first device can determine the second distance information based on the second measurement result of the SRS, the fourth distance information and the signal processing delay information of the second intelligent reflection plane. Optionally, the second measurement result can be the measurement result of the SRS transmitted through the second intelligent reflection plane.

[0085] Optionally, the second distance information may include N distance information. Therefore, in the above embodiment, the distance information between the terminal device and the N second intelligent reflective planes may be determined respectively, that is, the second distance information may be obtained.

[0086] Optionally, the first device may receive a second measurement result sent by a second access network device. Optionally, the second access network device may include N access network devices, and these N access network devices may respectively transmit signals with the terminal device via N second intelligent reflection planes. Optionally, the first device may respectively receive N second measurement results sent by the N second access network devices.

[0087] In some embodiments, the first device may calculate the distance between the terminal device and the first intelligent reflection plane (i.e., first distance information) based on the DL-PRS measurement result (such as reported by the first access network device), the distance information between the first access network device and the first intelligent reflection plane, and the signal processing delay information of the first intelligent reflection plane. Optionally, the first device may determine third distance information between the first access network device and the first intelligent reflection plane based on the location information of the first intelligent reflection plane; further, the first device may determine the first distance information based on the third measurement result of the DL-PRS, the third distance information, and the signal processing delay information. Optionally, the third measurement result may be a measurement result of the DL-PRS transmitted through the second intelligent reflection plane.

[0088] Optionally, if the first device is a LMF, the first device may receive the third measurement result sent by the terminal device.

[0089] Optionally, if the first device is a terminal device, the first device may measure the DL-PRS transmitted through the first smart reflection plane to obtain a third measurement result.

[0090] In some embodiments, the first device may calculate the distance between the terminal device and the second intelligent reflection plane based on the DL-PRS measurement result (such as reported by the second access network device), the distance information between the second access network device and the second intelligent reflection plane, and the signal processing delay information of the second intelligent reflection plane. Optionally, the first device may determine fourth distance information between the second access network device and the second intelligent reflection plane based on the location information of the second intelligent reflection plane; further, the first device may determine the second distance information based on the fourth measurement result of the DL-PRS, the fourth distance information, and the signal processing delay information of the second intelligent reflection plane. Optionally, the fourth measurement result may be a measurement result of the DL-PRS transmitted through the second intelligent reflection plane.

[0091] Optionally, if the first device is an LMF, the first device may receive the fourth measurement result sent by the terminal device.

[0092] Optionally, if the first device is a terminal device, the first device may measure the DL-PRS transmitted through the first smart reflection plane to obtain a fourth measurement result.

[0093] Optionally, the fourth measurement result may include N measurement results. For example, the fourth measurement result may include N measurement results of DL-PRS transmitted through N second smart reflection planes. Accordingly, the first device may receive the N measurement results (fourth measurement results) sent by the terminal device simultaneously or at different times, or the first device may measure the N DL-PRSs separately to obtain N measurement results (fourth measurement results).

[0094] In an embodiment of the present application, the first information includes position information and signal processing delay information of the first intelligent reflection plane. The first device receives the first information and determines the positioning result of the terminal device based on the first information, which helps to improve the positioning accuracy of the terminal device.
