[0054] It can be understood that the communication system described in the embodiment of the present disclosure is for the purpose of more clearly illustrating the technical solution of the embodiment of the present disclosure, and does not constitute a limitation on the technical solution provided by the embodiment of the present disclosure. A person skilled in the art can know that with the evolution of the system architecture and the emergence of new business scenarios, the technical solution provided by the embodiment of the present disclosure is also applicable to similar technical problems.
[0055] Generally, the contents that need to be measured and reported in the positioning method based on carrier phase include the fractional part and integer number of carrier phase. Among them, the fractional part of carrier phase refers to the fractional part that is less than a whole cycle, which is the phase measurement result of the signal sent by the received transmitter, or the result obtained by subtracting the phase of the reference signal generated by the receiver oscillator and the phase of the signal sent by the received transmitter. However, in the process of sending the reference signal, the transmitter needs to modulate the reference signal above the radio frequency, and in the process of receiving the reference signal, the receiver needs to demodulate the radio frequency signal. In the process of processing the radio frequency signal, the transmitter and the receiver may generate a phase error, which may affect the positioning accuracy. In the present disclosure, the devices send the phase error information generated by themselves when processing the radio frequency signal to the opposite device, thereby accurately positioning the carrier phase according to the phase error generated by processing the radio frequency signal, the fractional part of the carrier phase and the integer number of cycles, thereby improving the accuracy of the position information.
[0056] A carrier phase positioning method and device provided by the present disclosure are described in detail below in conjunction with the accompanying drawings.
[0057] See also Figure 2 , Figure 2 1 is a flow chart of a method for carrier phase positioning provided by an embodiment of the present disclosure, and the method is executed by a terminal device. Figure 2 As shown, the method may include but is not limited to the following steps:
[0058] Step 201: Send first indication information to a network device, wherein the first indication information is used to indicate phase error group information on a terminal device side.
[0059] The phase error group information, also called phase error group information, includes at least one of the following: a phase error group identification ID, and an error value corresponding to the phase error group ID. The network device may include a core network device and / or an access network device.
[0060] In the present disclosure, the phase error group ID may be any information that can uniquely identify the phase error group, such as a phase error group number, and the present disclosure does not impose any limitation on this.
[0061] The phase error group information may be at least one of the following: sending phase error group information, receiving phase error group information, and sending and receiving phase error group information.
[0062] Correspondingly, the above-mentioned first indication information may include at least one of the following items: sending phase error group ID, error value corresponding to sending phase error group ID, receiving phase error group ID, error value corresponding to receiving phase error group ID, sending and receiving phase error group ID, and error value corresponding to sending and receiving phase error group ID.
[0063] In the present disclosure, the phase error group may also be a timing error group (TEG).
[0064] In the present disclosure, the error value corresponding to the phase error group ID may be the phase difference between the two signals before and after modulation when the terminal device modulates the reference signal, or the phase difference between the two signals before and after demodulation when the terminal device demodulates the reference signal.
[0065] Correspondingly, the sending phase error can be the phase error generated when the terminal device modulates the reference signal, the receiving phase error can be the phase error generated when the terminal device demodulates the reference signal, and the sending and receiving phase error can be the phase error generated when the terminal device modulates and demodulates the reference signal. The reference signal can be any signal used for positioning. For example, it can be a positioning reference signal (PRS) used for positioning, or a sounding reference signal (SRS) used for positioning, or other reference signals used for positioning.
[0066] In the present disclosure, for the uplink reference signal, when positioning is performed based on the carrier phase, the network device can measure the reference signal through the phase of the reference signal generated by itself and / or the phase of the reference signal sent by the received terminal device. However, in the process of the terminal device sending the reference signal, the reference signal needs to be modulated. In the process of modulating the reference signal, a phase error may be generated, which affects the accuracy of positioning. Therefore, the terminal device can send the phase error group information corresponding to the phase error generated in the process of modulating the reference signal to the network device as phase error auxiliary information, so that the network device can determine the phase error generated by the terminal device in modulating the reference signal according to the phase error auxiliary information, and determine the position of the terminal device according to this phase error, the fractional part of the carrier phase and the integer number of cycles, thereby improving the accuracy of positioning.
[0067] In the present disclosure, for the downlink reference signal, when positioning is performed based on the carrier phase, the terminal device can measure the reference signal through the phase of the reference signal generated by itself and / or the phase of the reference signal sent by the received network device. However, in the process of the terminal receiving the reference signal, the reference signal needs to be demodulated, and in the process of demodulating the reference signal, a phase error may be generated, affecting the accuracy of positioning. Therefore, the terminal device can send the phase error group information corresponding to the phase error generated in the process of demodulating the reference signal as phase error auxiliary information to the network device, so that the network device can determine the phase error generated by the terminal device in demodulating the reference signal based on the phase error auxiliary information, and determine the position of the terminal device based on this phase error, the fractional part of the carrier phase and the integer number of cycles, thereby improving the accuracy of positioning.
[0068] In the present disclosure, the terminal device sends a first indication information to the network device for indicating the phase error group information on the terminal device side. After that, the network device can determine the phase error generated by the terminal device in modulating or demodulating the reference signal based on the first indication information, and determine the terminal position based on this phase error, the decimal part of the carrier phase and the integer number of cycles, thereby improving the accuracy of positioning.
[0069] See also Figure 3 , Figure 3 1 is a flow chart of a method for carrier phase positioning provided by an embodiment of the present disclosure, and the method is executed by a terminal device. Figure 3 As shown, the method may include but is not limited to the following steps:
[0070] Step 301: Send first indication information to a network device, wherein the first indication information includes measurement results and terminal device side phase error group information corresponding to each measurement result.
[0071] The terminal device side phase error group information may include at least one of the following: receiving phase error group information, sending and receiving phase error group information. The specific explanation of the phase error group information can be found in the detailed description of any embodiment of the present disclosure, which will not be repeated here.
[0072] The measurement result is a measurement result of the terminal device measuring the received reference signal, which may include at least one of the fractional part and the integer number of the carrier phase.
[0073] In addition, the measurement result may further include at least one of the following: reference signal received power, angle of arrival (Angle of Arrival), angle of departure (Angle of Departure), time of arrival (Time of Arrival), time difference of arrival (Time Difference of Arrival), round trip time (Round Trip Time), receive time error (Rx time error group, REG) identifier or error value, send time error group (Tx time error group, TEG) identifier or error value, and send and receive time error group (Tx Rx time error group, TREG) identifier or error value.
[0074] In addition, the network equipment may include core network equipment and / or access network equipment.
[0075] In the present disclosure, the receiving phase error may be a phase error generated when the terminal device demodulates a reference signal, and the sending and receiving phase error may be a phase error generated when the terminal device modulates and demodulates a reference signal. The reference signal may be any downlink reference signal used for positioning.
[0076] In the present disclosure, when positioning is performed based on carrier phase, after the terminal device measures the downlink reference signal, it can send the measurement result to the network device, so that the network device can determine the position of the terminal device based on the measurement result. However, due to the influence of the phase error generated when the terminal device demodulates the reference signal sent by the received network device, it is not accurate enough to determine the position of the terminal device based on the measurement result alone. Therefore, the phase error group information generated by the terminal device when demodulating the reference signal can be sent to the network device as the terminal device side phase error group information corresponding to the measurement result. Thereby, the network device can determine the phase error generated by the terminal device when demodulating the reference signal when obtaining the measurement result based on the phase error group information, and determine the position of the terminal device based on this phase error and the corresponding measurement result, thereby improving the accuracy of positioning.
[0077] In the present disclosure, a terminal device may send a first indication message including a measurement result and terminal device side phase error group information corresponding to each measurement result to a network device. Thereafter, the network device may determine, based on the first indication message, a phase error generated by a demodulated reference signal when the terminal device obtains the measurement result, and determine the position of the terminal device based on the phase error and the corresponding measurement result, thereby improving the accuracy of positioning.
[0078] See also Figure 4 , Figure 41 is a flow chart of a method for carrier phase positioning provided by an embodiment of the present disclosure, and the method is executed by a terminal device. Figure 4 As shown, the method may include but is not limited to the following steps:
[0079] Step 401: Send first indication information to a network device, wherein the first indication information includes terminal device side phase error group information corresponding to each reference signal.
[0080] The network equipment may include core network equipment and / or access network equipment.
[0081] Optionally, the reference signal may be a positioning reference signal (PRS), or a sounding reference signal (SRS) used for positioning, or other reference signals used for positioning, etc., which is not limited in the present disclosure.
[0082] Optionally, different types of reference signals may correspond to different terminal device side phase error group information. For example, when the reference signal is an uplink reference signal, the terminal device side phase error group information may be sending phase error group information and / or sending and receiving phase error group information. For a specific explanation of the phase error group information, please refer to the detailed description of any embodiment of the present disclosure, which will not be repeated here.
[0083] In the present disclosure, when positioning is performed based on carrier phase, it includes the terminal device sending an uplink reference signal, and the network device receiving the uplink reference signal and measuring it. After the terminal device modulates the uplink reference signal into a radio frequency signal, a phase error will be generated. Therefore, the phase error group information corresponding to the phase error generated by the terminal device in the process of modulating the reference signal can be sent to the network device as the terminal device side phase error group information corresponding to the reference signal. Thus, the network device can determine the phase error generated by the terminal device when modulating the reference signal according to the terminal device side phase error group information corresponding to the reference signal. After that, the position of the terminal device can be determined according to the phase error and the measurement result of the measured reference signal, thereby improving the accuracy of positioning.
[0084] In the present disclosure, the terminal device can send a first indication message including terminal device side phase error group information corresponding to each reference signal to the network device. Thereafter, the network device can determine the phase error generated by the terminal device when modulating the reference signal based on the phase error group information corresponding to the reference signal, and determine the terminal position based on the phase error and the measurement result of the reference signal, thereby improving the positioning accuracy.
[0085] See also Figure 5 , Figure 5 1 is a flow chart of a method for carrier phase positioning provided by an embodiment of the present disclosure, and the method is executed by a terminal device. Figure 5 As shown, the method may include but is not limited to the following steps:
[0086] Step 501: Send first indication information to a network device, wherein the first indication information is used to indicate phase error group information on a terminal device side.
[0087] In the present disclosure, the specific implementation process of step 501 can be found in the detailed description of any embodiment in the present disclosure, and will not be repeated here.
[0088] Step 502: In response to the phase error group information being a phase error group ID, second indication information is sent to the network device, wherein the second indication information is used to indicate an error value corresponding to each phase error group ID.
[0089] In the present disclosure, when the phase error group information is a phase error group ID, the terminal device can also send the error value corresponding to each phase error group ID to the network device. Thus, the network device can determine the error value corresponding to the group according to the phase error group ID, and determine the position of the terminal device according to the phase error and the measurement result, thereby improving the accuracy of positioning.
[0090] It should be noted that after the terminal device sends the phase error group ID to the network device, it may not separately indicate the error value corresponding to each phase error group ID. The network device determines the error value corresponding to the phase error group ID according to the protocol agreement, and the present disclosure does not limit this.
[0091] In the present disclosure, the terminal device can send first indication information for indicating the phase error group information on the terminal device side to the network device. When the phase error group information is a phase error group ID, second indication information for indicating the error value corresponding to each phase error group ID can be sent to the network device. Thereafter, the network device can determine the error value corresponding to the phase error group according to the phase error group ID, and determine the terminal position according to the error value and the test result, thereby improving the accuracy of positioning.
[0092] See also Figure 6 , Figure 61 is a flow chart of a method for carrier phase positioning provided by an embodiment of the present disclosure, and the method is executed by a network device. The network device may include a core network device and / or an access network device. Figure 8 As shown, the method may include but is not limited to the following steps:
[0093] Step 601: Receive first indication information sent by a terminal device, wherein the first indication information is used to indicate phase error group information on the terminal device side.
[0094] The phase error group information, also referred to as phase error group information, includes at least one of the following: a phase error group identifier ID, and an error value corresponding to the phase error group ID.
[0095] In the present disclosure, the phase error group identification ID may be any information that can uniquely identify the phase error group, such as a phase error group number, and the present disclosure does not impose any limitation on this.
[0096] The phase error group information may be at least one of the following: sending phase error group information, receiving phase error group information, and sending and receiving phase error group information.
[0097] In the present disclosure, the phase error group may also be a timing error group (TEG).
[0098] In the present disclosure, the error value corresponding to the phase error group ID may be the phase difference between the two signals before and after modulation when the terminal device modulates the reference signal, or the phase difference between the two signals before and after demodulation when the terminal device demodulates the reference signal.
[0099] Correspondingly, the sending phase error can be the phase error generated when the terminal device modulates the reference signal, the receiving phase error can be the phase error generated when the terminal device demodulates the reference signal, and the sending and receiving phase error can be the phase error generated when the terminal device modulates and demodulates the reference signal. The reference signal can be any signal used for positioning. For example, it can be a positioning reference signal (PRS) used for positioning, or a sounding reference signal (SRS) used for positioning, or other reference signals used for positioning.
[0100] In the present disclosure, corresponding to the uplink reference signal, when positioning is performed based on the carrier phase, the network device can measure the reference signal through the phase of the reference signal generated by itself and / or the phase of the reference signal sent by the received terminal device. However, in the process of the terminal device sending the reference signal, the reference signal needs to be modulated. In the process of modulating the reference signal, a phase error may be generated, which affects the accuracy of positioning. Therefore, the terminal device can send the phase error group information corresponding to the phase error generated in the process of modulating the reference signal to the network device as phase error auxiliary information, so that the network device can determine the phase error generated by the terminal device in modulating the reference signal according to the phase error auxiliary information, and determine the position of the terminal device according to this phase error, the fractional part of the carrier phase and the integer number of cycles, thereby improving the accuracy of positioning.
[0101] In the present disclosure, for the downlink reference signal, when positioning is performed based on the carrier phase, the terminal device can measure the reference signal through the phase of the reference signal generated by itself and / or the phase of the reference signal sent by the received network device. However, in the process of the terminal receiving the reference signal, the reference signal needs to be demodulated, and in the process of demodulating the reference signal, a phase error may be generated, affecting the accuracy of positioning. Therefore, the terminal device can send the phase error group information corresponding to the phase error generated in the process of demodulating the reference signal as phase error auxiliary information to the network device, so that the network device can determine the phase error generated by the terminal device in demodulating the reference signal based on the phase error auxiliary information, and determine the position of the terminal device based on this phase error, the fractional part of the carrier phase and the integer number of cycles, thereby improving the accuracy of positioning.
[0102] In the present disclosure, a network device can receive first indication information sent by a terminal device for indicating phase error group information on the terminal device side. Afterwards, the network device can determine the phase error generated by the terminal device in modulating or demodulating a reference signal based on the phase error auxiliary information, and determine the terminal position based on this phase error, the decimal part of the carrier phase and the integer number of cycles, thereby improving the accuracy of positioning.
[0103] See also Figure 7 , Figure 7 1 is a flow chart of a method for carrier phase positioning provided by an embodiment of the present disclosure, and the method is executed by a network device. The network device may include a core network device and / or an access network device. Figure 7 As shown, the method may include but is not limited to the following steps:
[0104] Step 701: Receive first indication information sent by a terminal device, wherein the first indication information includes terminal device side phase error group information corresponding to each measurement result.
[0105] The terminal device side phase error group information may include at least one of the following: receiving phase error group information, sending and receiving phase error group information. The specific explanation of the phase error group information can be found in the detailed description of any embodiment of the present disclosure, which will not be repeated here.
[0106] The measurement result includes at least one of the fractional part and the integer number of the carrier phase. In addition, the measurement result may further include at least one of the following: reference signal received power, angle of arrival, angle of departure, time of arrival, time difference of arrival, round trip time, Rx time error group (REG) identifier or error value, Tx time error group (TEG) identifier or error value, and Tx Rx time error group (TREG) identifier or error value.
[0107] In the present disclosure, the receiving phase error may be a phase error generated when the terminal device demodulates a reference signal, and the sending and receiving phase error may be a phase error generated when the terminal device modulates and demodulates a reference signal. The reference signal may be any downlink reference signal used for positioning.
[0108] In the present disclosure, when positioning is performed based on carrier phase, after the terminal device measures the downlink reference signal, it can send the measurement result to the network device, so that the network device can determine the position of the terminal device based on the measurement result. However, due to the influence of the phase error generated when the terminal device demodulates the reference signal sent by the received network device, it is not accurate enough to determine the position of the terminal device based on the measurement result alone. Therefore, the phase error group information generated by the terminal device when demodulating the reference signal can be sent to the network device as the terminal device side phase error group information corresponding to the measurement result. Thereby, the network device can determine the phase error generated by the terminal device when demodulating the reference signal when obtaining the measurement result based on the phase error group information, and determine the position of the terminal device based on this phase error and the corresponding measurement result, thereby improving the accuracy of positioning.
[0109] In the present disclosure, a network device can receive a first indication message sent by a terminal device, including terminal device side phase error group information corresponding to each measurement result. Thereafter, the network device can determine, based on the first indication message, a phase error generated by a demodulated reference signal when the terminal device obtains the measurement result, and determine the position of the terminal device based on this phase error and the corresponding measurement result, thereby improving the accuracy of positioning.
[0110] See also Figure 8 , Figure 8 1 is a flow chart of a method for carrier phase positioning provided by an embodiment of the present disclosure, and the method is executed by a network device. The network device may include a core network device and / or an access network device. Figure 8 As shown, the method may include but is not limited to the following steps:
[0111] Step 801: Receive first indication information sent by a terminal device, where the first indication information includes terminal device side phase error group information corresponding to each reference signal.
[0112] Optionally, the reference signal may be a positioning reference signal (PRS), or a sounding reference signal (SRS) used for positioning, or other reference signals used for positioning, etc., which is not limited in the present disclosure.
[0113] Optionally, different types of reference signals may correspond to different terminal device side phase error group information. For example, when the reference signal is an uplink reference signal, the terminal device side phase error group information may be sending phase error group information and / or sending and receiving phase error group information. For a specific explanation of the phase error group information, please refer to the detailed description of any embodiment of the present disclosure, which will not be repeated here.
[0114] In the present disclosure, when positioning is performed based on carrier phase, it includes the terminal device sending an uplink reference signal, and the network device receiving the uplink reference signal and measuring it. After the terminal device modulates the uplink reference signal into a radio frequency signal, a phase error will be generated. Therefore, the phase error group information corresponding to the phase error generated by the terminal device in the process of modulating and demodulating the reference signal can be sent to the network device as the terminal device side phase error group information corresponding to the reference signal. Thus, the network device can determine the phase error generated by the terminal device when modulating the reference signal according to the terminal device side phase error group information corresponding to the reference signal. After that, the position of the terminal device can be determined according to the phase error and the measurement result of the measured reference signal, thereby improving the accuracy of positioning.
[0115] In the present disclosure, a network device can receive first indication information sent by a terminal device, including terminal device side phase error group information corresponding to each reference signal. Afterwards, the network device can determine the phase error generated by the terminal device when modulating the reference signal based on the phase error group information corresponding to the reference signal, and determine the terminal position based on the phase error and the measurement results of the reference signal, thereby improving the positioning accuracy.
[0116] See also Fig. 9 , Fig. 9 1 is a flow chart of a method for carrier phase positioning provided by an embodiment of the present disclosure, and the method is executed by a network device. The network device may include a core network device and / or an access network device. Fig. 9 As shown, the method may include but is not limited to the following steps:
[0117] Step 901: Receive first indication information sent by a terminal device, wherein the first indication information is used to indicate phase error group information on the terminal device side.
[0118] In the present disclosure, the specific implementation process of step 901 can be found in the detailed description of any embodiment in the present disclosure, and will not be repeated here.
[0119] Step 902: Receive second indication information sent by the terminal device, where the second indication information is used to indicate an error value corresponding to each phase error group ID in the phase error group information.
[0120] In the present disclosure, when the phase error group information is a phase error group ID, the terminal device may also send the error value corresponding to each phase error group ID to the network device. Thus, the network device may determine the error value corresponding to the phase error group ID according to the phase error group ID, and determine the position of the terminal device according to the phase error and the measurement result, thereby improving the accuracy of positioning.
[0121] It should be noted that after the terminal device sends the phase error group ID to the network device, it may not separately indicate the error value corresponding to each phase error group ID. The network device determines the error value corresponding to the phase error group ID according to the protocol agreement, and the present disclosure does not limit this.
[0122] In the present disclosure, a network device can receive first indication information sent by a terminal device for indicating phase error group information on the terminal device side. When the phase error group information is a phase error group ID, a network device can receive second indication information for indicating an error value corresponding to each phase error group ID in the phase error group information. Afterwards, the network device can determine the error value corresponding to the phase error group based on the phase error group ID, and determine the terminal position based on the error value and the test result, thereby improving the accuracy of positioning.
