Fig. 4 is a flowchart of a positioning measurement method based on carrier phase according to an embodiment of the present application. The method is performed by a first device. The method comprises the following steps:

step 401, a first positioning usage reference signal is received, and a received carrier phase corresponding to the first positioning usage reference signal is determined.

The first device comprises at least one of a terminal device and an access network device. The first positioning usage reference signal is different for different first devices. The first positioning-purpose reference signal comprises at least one of a positioning reference signal (Positioning Reference Signal, PRS) and a sounding reference signal (Sounding Reference Signal, SRS).

Optionally, when the first device is a terminal device, the first positioning usage reference signal is a downlink positioning usage reference signal sent by the access network device. The downlink positioning use reference signal may be a PRS, or other signal used for positioning.

Optionally, when the first device is an access network device, the first positioning usage reference signal is an uplink positioning usage reference signal sent by the terminal device. The uplink positioning use reference signal may be an SRS, or other signal used for positioning. An access network device in embodiments of the present application may refer to a base station (e.g., a gNB), or a transmission-reception point (Transmission Reception Point, TRP).

In the embodiment of the present application, when receiving the first positioning usage reference signal, the first device determines a received carrier phase corresponding to a receiving time of the first positioning usage reference signal. The first device may receive a plurality of first positioning use reference signals from different devices, and determine a received carrier phase corresponding to a reception time of each first positioning use reference signal when each first positioning use reference signal is received.

Illustratively, when the first device is a terminal device, the terminal device may receive PRSs sent from different access network devices, and determine a received carrier phase for each PRS receive time.

Step 402, transmitting a second positioning purpose reference signal, and determining a transmission carrier phase corresponding to the second positioning purpose reference signal.

Accordingly, the second location use reference signal is different for different first devices. The second positioning use reference signal comprises at least one of a positioning reference signal (Positioning Reference Signal, PRS) and a sounding reference signal (Sounding Reference Signal, SRS).

Optionally, when the first device is a terminal device, the second positioning usage reference signal is an uplink positioning usage reference signal sent by the terminal device to the access network device. When the first device is an access network device, the second positioning purpose reference signal is a downlink positioning purpose reference signal sent by the access network device to the terminal device.

The first device determines a transmission carrier phase corresponding to the transmission time when transmitting the second positioning use reference signal. Similarly, the first device may transmit the second positioning use reference signals to a plurality of different devices, and determine a transmission carrier phase corresponding to a transmission time of each second positioning use reference signal when transmitting each second positioning use reference signal.

Illustratively, when the first device is a terminal device, the terminal device may send SRS to different access network devices, and determine a transmission carrier phase of each SRS transmission time.

Step 403, determining a receive transmit carrier phase difference value based on the receive carrier phase and the transmit carrier phase.

After determining the received carrier phase and the transmitted carrier phase, the first device may determine a received-transmitted carrier phase difference value between the received carrier phase and the transmitted carrier phase, and obtain a variation value of the carrier phase between the transmission time and the reception time.

The transmission time and the reception time do not have a sequence, and only indicate the time of transmitting the signal and the time of receiving the signal.

Schematically, when the first device is at t ₁ When the first positioning purpose reference signal is received at the moment, the first equipment determines t ₁ A received carrier phase of the time first positioning use reference signal; when the first device is at t ₂ When the second positioning purpose reference signal is transmitted at the moment, the first equipment determines t ₂ Determining t based on the received carrier phase and the transmitted carrier phase of the reference signal for the second positioning use at the moment ₁ Time and t ₂ The value of the carrier phase change between moments.

In one possible implementation manner, the first devices may determine the received and transmitted carrier phase difference values for different third devices respectively, and the different first devices each determine a corresponding received and transmitted carrier phase difference value, so that the core network device realizes positioning according to the different received and transmitted carrier phase difference values. When the first equipment is terminal equipment, the third equipment is access network equipment; and when the first equipment is access network equipment, the third equipment is terminal equipment.

As shown in fig. 5, in an exemplary scenario, the terminal device 101 may receive downlink positioning usage reference signals from three access network devices, including a first downlink positioning usage reference signal sent by the first access network device 502, a second downlink positioning usage reference signal sent by the second access network device 503, and a third downlink positioning usage reference signal sent by the third access network device 504; and the terminal device 101 may send a first uplink positioning usage reference signal to the first access network device 502, a second uplink positioning usage reference signal to the second access network device 503, and a third uplink positioning usage reference signal to the third access network device 504, respectively.

The terminal device 101 determines at t ₁ A first received carrier phase when receiving a first downlink positioning use reference signal at a time, t ₂ A first transmission carrier phase when transmitting the first uplink positioning use reference signal at a moment, and determining a first reference carrier according to the first reception carrier phase and the first transmission carrier phaseA first receiving transmit carrier phase difference value of the access network device 502; and is determined at t ₃ A second received carrier phase when receiving the second downlink positioning use reference signal at time t ₄ A second transmit carrier phase when the second uplink positioning usage reference signal is transmitted at a moment, and determining a second receive transmit carrier phase difference value for the second access network device 503 according to the second receive carrier phase and the second transmit carrier phase; and is determined at t ₅ A third received carrier phase when receiving a third downlink positioning use reference signal at time t ₆ And determining a third receiving and transmitting carrier phase difference value for the third access network device 504 according to the third receiving carrier phase and the third transmitting carrier phase.

And the first access network device 502 may determine a fourth received carrier phase when receiving the first uplink positioning use reference signal and determine a fourth transmitted carrier phase when transmitting the first downlink positioning use reference signal, thereby determining a fourth received transmitted carrier phase difference value; the second access network device 503 may determine a fifth received carrier phase when receiving the second uplink positioning usage reference signal, and determine a fifth transmitted carrier phase when transmitting the second downlink positioning usage reference signal, thereby determining a fifth received transmitted carrier phase difference value; and the third access network device 504 may determine a sixth received carrier phase when receiving the third uplink positioning use reference signal and determine a sixth transmitted carrier phase when transmitting the third downlink positioning use reference signal, thereby determining a sixth received transmitted carrier phase difference value. The terminal device 101, the first access network device 502, the second access network device 503, and the third access network device 504 respectively send each received and sent carrier phase difference value to the core network device 103, the core network device 103 calculates a distance D1 between the terminal device 101 and the first access network device 502, a distance D2 between the terminal device 101 and the second access network device 503, and a distance D3 between the terminal device 101 and the third access network device 504 according to each received and sent carrier phase difference value, and then, the core network device 103 may determine the position coordinates of the terminal device based on the three distances (D1, D2, and D3) and the position coordinates of the three access network devices.

In summary, in the embodiment of the present application, the first device determines the received carrier phase corresponding to the received reference signal for positioning purposes, and determines the transmitted carrier phase corresponding to the transmitted reference signal for positioning purposes, so as to obtain the received and transmitted carrier phase difference value, which can be used for positioning of the first device. In the embodiment of the application, the positioning is performed according to the change condition of the carrier phase, so that the positioning measurement based on the carrier phase is realized, and the positioning precision can be improved.

Fig. 6 is a flowchart of a positioning measurement method based on carrier phase according to another embodiment of the present application. The method is performed by a first device. The method comprises the following steps:

step 601, receiving a first positioning use reference signal, and determining a received carrier phase corresponding to a reception time of the first positioning use reference signal.

Optionally, when the first device is a terminal device, the received carrier phase is a carrier phase corresponding to when the terminal device receives the downlink positioning use reference signal at the first time. Namely, the terminal equipment receives the reference signal for downlink positioning and determines the received carrier phase of the reference signal for downlink positioning at the first time.

Optionally, when the first device is an access network device, the received carrier phase is a carrier phase corresponding to when the access network device receives the uplink positioning use reference signal at the third time. That is, the access network device receives the uplink positioning use reference signal, and determines a received carrier phase for receiving the uplink positioning use reference signal at the third time.

Step 602, transmitting a second positioning purpose reference signal, and determining a transmission carrier phase corresponding to a transmission time of the second positioning purpose reference signal.

Optionally, when the first device is a terminal device, the transmitting carrier phase is a carrier phase corresponding to when the terminal device transmits the uplink positioning use reference signal at the second time. That is, the terminal device transmits the uplink positioning use reference signal, and determines a transmission carrier phase for transmitting the uplink positioning use reference signal at the second time.

Optionally, when the first device is an access network device, the sending carrier phase is a carrier phase corresponding to when the access network device sends the reference signal for downlink positioning at the fourth time. That is, the access network device transmits the reference signal for downlink positioning, and determines the transmission carrier phase for transmitting the reference signal for downlink positioning at the fourth time.

It should be noted that, the first time, the second time, the third time, and the fourth time do not have a sequence, and only indicate the time of receiving or transmitting the signal.

In one possible scenario, as shown in fig. 7, the TRP first transmits a downlink positioning use reference signal to the UE at a fourth time, the UE receives the downlink positioning use reference signal transmitted by the TPR at the first time, and transmits an uplink positioning use reference signal to the TRP at a second time, and the TRP receives the uplink positioning use reference signal transmitted by the UE at a third time. The UE may determine the first received transmit carrier phase difference value 701 from the received carrier phase corresponding to the first time (i.e., the receive time) and the transmit carrier phase corresponding to the second time (i.e., the transmit time), and the trp may determine the second received transmit carrier phase difference value 702 from the received carrier phase corresponding to the third time (i.e., the receive time) and the transmit carrier phase corresponding to the fourth time (i.e., the transmit time).

In yet another possible scenario, as shown in fig. 8, the UE first transmits an uplink positioning purpose reference signal to the TRP at a second time, the TRP receives the uplink positioning purpose reference signal transmitted by the UE at a third time, and transmits a downlink positioning purpose reference signal to the UE at a fourth time, the UE receives the downlink positioning purpose reference signal at the first time. The UE may determine the first received transmit carrier phase difference value 801 from the received carrier phase corresponding to the first time (i.e., the receive time) and the transmit carrier phase corresponding to the second time (i.e., the transmit time), and the trp may determine the second received transmit carrier phase difference 802 from the received carrier phase corresponding to the third time (i.e., the receive time) and the transmit carrier phase corresponding to the fourth time (i.e., the transmit time).

That is, there is no sequence of the sending time of the signal sent by the first device and the receiving time of the received signal, and the first device only needs to determine the variation value of the carrier phase between the sending time and the receiving time.

Step 603, determining a receive transmit carrier phase difference value based on the receive carrier phase and the transmit carrier phase.

Optionally, when the first device is a terminal device, the received and transmitted carrier phase difference value is a value of a change that the carrier phase measured by the terminal device experiences between the first time and the second time.

Optionally, when the first device is an access network device, the received and transmitted carrier phase difference value is a value of a change that the access network device measured carrier phase experiences between the third time and the fourth time.

Wherein the receive transmit carrier phase difference value comprises at least one of a whole number of weeks and a fractional portion of less than the whole number of weeks. The phase-locked loop of the first device locks to fractional parts less than the full circumference, and the counter of the first device can keep track of the number of changes in phase over the full circumference. That is, the received transmit carrier phase difference value includes not only the difference of less than the entire period of the phase locked loop between the transmit time and the receive time, but also the number of entire periods that have been experienced. For example, when the reception time is early, the reception carrier phase at the reception time contains only a fraction of less than the whole circumference, and when the transmission time is elapsed, the transmission carrier phase at the transmission time contains the whole circumference and the phase-locked loop shows a fraction of less than the whole circumference, and the reception transmission carrier phase difference is obtained by subtracting the fraction of less than the whole circumference corresponding to the reception carrier phase from the transmission carrier phase.

Schematically, as shown in FIG. 9, which shows a first device at a time of receipt t ₀ To the transmission time t ₁ Carrier phase change map of (a). At the time of reception t ₀ And transmission time t ₁ And then undergoes 0.3 wavelengths after 5 cycles, so the phase difference of the receiving and transmitting carriers comprises the whole cycle number of 5 and the fractional part of less than the whole cycle number of 0.3.

In combination with the above example, in the scenario shown in fig. 7, the first receiving-transmitting carrier phase difference 701 of the UE is the fractional part of the carrier phase integer and possibly the less than integer circumference that the phase-locked loop of the terminal experiences from the first time to the second time, and the second receiving-transmitting carrier phase difference 702 of the TRP is the fractional part of the carrier phase integer and possibly the less than integer circumference that the phase-locked loop of the TRP end experiences from the fourth time to the third time.

Step 604, transmitting a receive transmit carrier phase difference value to the second device, the receive transmit carrier phase difference value comprising at least one of a whole number of weeks and a fractional portion of less than the whole circumference.

Alternatively, the first device may send a positioning measurement report to the second device, which performs positioning according to the positioning measurement report.

Optionally, the second device comprises a core network device. A location server in the core network may determine the location of the terminal device based on the positioning measurement report.

In this embodiment, after determining the received and transmitted carrier phase difference value, the first device may send the received and transmitted carrier phase difference value to the second device. The second device determines the round-trip carrier phase difference between the different first devices according to the received and transmitted carrier phase difference values sent by the different first devices, thereby determining the round-trip time of the signals.

In one possible implementation, the second device may receive a first received transmit carrier phase difference value from the terminal device and a second received transmit carrier phase difference value from the access network device, and determine a round-trip carrier phase difference between the terminal device and the access network device based on a difference between the first received transmit carrier phase difference value and the second received transmit carrier phase difference value.

In combination with the above example, in the scenario shown in fig. 7, the round-trip carrier phase difference is the phase difference obtained by subtracting the first received and transmitted carrier phase difference 701 from the second received and transmitted carrier phase difference 702. In the scenario shown in fig. 8, the round-trip carrier phase difference is the phase difference obtained by subtracting the second received-transmitted carrier phase difference value 802 from the first received-transmitted carrier phase difference 801.
