In the related technology, a fuzzy problem exists for the phase full cycle of the positioning signal, and in order to solve the problem of the phase full cycle fuzzy degree, usually, positioning signals are transmitted using multiple carrier frequencies with different wavelengths but the same transmission distance, respectively, to solve the phase full cycle fuzzy problem.

[0072] As described above, in the signal processing method provided by the embodiment of the present disclosure, the user equipment obtains carrier frequency information of at least two carrier frequencies set by the network device, and the carrier frequencies are used to transmit positioning signals, and then the user equipment obtains positioning signal resources corresponding to each carrier frequency set by the network device, and the user equipment transmits positioning signals according to the carrier frequency information and positioning signal resources of the at least two carrier frequencies, and the access network device receives the positioning signals, measures them, obtains a positioning report, and reports them to the core network device. From this, it can be seen that the present disclosure provides a method for setting multi-carrier frequency positioning signals and a method for reporting measurement reports for multi-carrier frequency scenarios, thereby solving the technical problem of "how to set multi-carrier frequency positioning signals and how to report measurement reports".

[0073] FIG. 3 is a schematic flowchart of a signal processing method provided by an embodiment of the present disclosure, which is executed by a UE and can be used for uplink positioning. As shown in FIG. 3, the method can include the following steps 301-304.

[0074] In step 301, capability information is reported.

[0075] In one embodiment of the present disclosure, this capability information can be used to indicate whether the UE supports simultaneous transmission of positioning signals on multiple carrier frequencies.

[0077] In step 302, carrier frequency information of at least two carrier frequencies configured by a core network device is obtained.

[0078] In step 303, obtain positioning signal resources corresponding to each carrier frequency configured by the core network device.

[0079] In one embodiment of the present disclosure, if the above capability information indicates that the UE supports simultaneous transmission of positioning signals on multiple carrier frequencies, the core network device can configure positioning signal resources in the same time domain and / or different time domains on each carrier frequency, so as to enable simultaneous or non-simultaneous transmission of positioning signals on the multiple carrier frequencies.

[0080] In another embodiment of the present disclosure, if the capability information indicates that the UE does not support simultaneous transmission of positioning signals on multiple carrier frequencies, the core network device can only configure positioning signal resources of different time domains on each carrier frequency. , thereby enabling non-simultaneous transmission of positioning signals at multiple carrier frequencies.

[0081] In step 304, a positioning signal is transmitted based on carrier frequency information of at least two carrier frequencies and a positioning signal resource.

[0082] In one embodiment of the present disclosure, if the above capability information indicates that the UE supports simultaneous transmission of positioning signals on multiple carrier frequencies, the core network device can configure positioning signal resources of the same time domain and / or different time domains on each carrier frequency, and the UE needs to transmit positioning signals simultaneously and / or non-simultaneously on the positioning signal resources on at least two carrier frequencies. In another embodiment of the present disclosure, if the above capability information does not support the UE supports simultaneous transmission of positioning signals on multiple carrier frequencies, the core network device can only configure positioning signal resources of different time domains on each carrier frequency, and the UE needs to transmit positioning signals non-simultaneously on the positioning signal resources on at least two carrier frequencies.

[0083] In one embodiment of the present disclosure, the above step 301 is selectively performed. Specifically, in one embodiment of the present disclosure, when the UE transmits a positioning signal, the UE can report the above capability information by performing the above step 301. In addition, when the UE subsequently transmits a positioning signal, if the UE's capability of "whether to support simultaneous transmission of positioning signals at multiple carrier frequencies" does not change, the UE does not need to perform the above step 301 (i.e., the UE does not report this capability information), and if the UE's capability of "whether to support simultaneous transmission of positioning signals at multiple carrier frequencies" changes, the UE can perform the above step 301 (the UE needs to update and report this capability information).

[0084] As described above, in the signal processing method provided by the embodiment of the present disclosure, the user equipment obtains carrier frequency information of at least two carrier frequencies set by the network device, and the carrier frequencies are used to transmit positioning signals, and then the user equipment obtains positioning signal resources corresponding to each carrier frequency set by the network device, and the user equipment transmits positioning signals according to the carrier frequency information and positioning signal resources of the at least two carrier frequencies, and the access network device receives the positioning signals, measures them, obtains a positioning report, and reports them to the core network device. From this, it can be seen that the present disclosure provides a method for setting multi-carrier frequency positioning signals and a method for reporting measurement reports for multi-carrier frequency scenarios, thereby solving the technical problem of "how to set multi-carrier frequency positioning signals and how to report measurement reports".

[0085] FIG. 4 is a schematic flowchart of a signal processing method provided by an embodiment of the present disclosure, which is executed by a UE and can be used for uplink positioning. As shown in FIG. 4, the method can include the following steps 401-404.

[0086] In step 401, carrier frequency information of at least two carrier frequencies configured by a core network device is obtained, and the carrier frequencies are used to transmit positioning signals.

[0087] In step 402, obtain positioning signal resources corresponding to each carrier frequency configured by the core network device.

[0088] In step 403, information (such as auxiliary information) is reported.

[0089] In one embodiment of the present disclosure, this information includes: phase error group information when the UE transmits the positioning signal, the phase error group information including an ID of a phase error group and / or an error value corresponding to the phase error group; and timing error group information when the UE transmits the positioning signal, the timing error group information including an ID of a timing error group and / or an error value corresponding to the timing error group.

[0090] In addition, the UE can specifically report the above information to the core network device so that the core network device can take into account the influence of the error information when subsequently performing positioning calculation based on the positioning report, thereby ensuring positioning accuracy; and / or the UE can specifically report the above information to the access network device so that the access network device can subsequently receive and measure the positioning signal transmitted from the UE based on the above information, thereby ensuring positioning accuracy.

[0091] In step 404, a positioning signal is transmitted based on carrier frequency information of at least two carrier frequencies and a positioning signal resource.

[0092] For other detailed explanations regarding steps 401 to 404, refer to the explanations of the above embodiments, and the explanations of the embodiments of the present disclosure will be omitted here.

[0093] It should be noted that the above step 403 is selectively performed. Specifically, in one embodiment of the present disclosure, when the UE transmits a positioning signal, the UE can report the above information by performing the above step 403. Also, when the UE subsequently transmits a positioning signal, if the current corresponding information of the UE (i.e., the phase error group information and / or the timing error group information when the UE currently transmits the positioning signal) does not change compared with the information previously reported by the UE, the UE does not need to perform the above step 403 (i.e., does not report this information); if the current corresponding information of the UE changes compared with the information previously reported by the UE, the UE can perform the above step 403 (the UE needs to update and report this information).

[0094] Also, in one embodiment of the present disclosure, the above steps 403 and 404 may be performed in any order, ie, 403 may be performed before, after, or simultaneously with 404.

[0095] As described above, in the signal processing method provided by the embodiment of the present disclosure, the user equipment obtains carrier frequency information of at least two carrier frequencies set by the network device, and the carrier frequencies are used to transmit positioning signals, and then the user equipment obtains positioning signal resources corresponding to each carrier frequency set by the network device, and the user equipment transmits positioning signals according to the carrier frequency information and positioning signal resources of the at least two carrier frequencies, and the access network device receives the positioning signals, measures them, obtains a positioning report, and reports them to the core network device. From this, it can be seen that the present disclosure provides a method for setting multi-carrier frequency positioning signals and a method for reporting measurement reports for multi-carrier frequency scenarios, thereby solving the technical problem of "how to set multi-carrier frequency positioning signals and how to report measurement reports".

[0096] FIG. 5 is a schematic flowchart of a signal processing method provided by an embodiment of the present disclosure, which is executed by a UE and can be used for uplink positioning. As shown in FIG. 5, the method can include the following steps 501-504.

[0097] In step 501, carrier frequency information of at least two carrier frequencies configured by a core network device is obtained, and the carrier frequencies are used to transmit positioning signals.

[0098] In step 502, obtain positioning signal resources corresponding to each carrier frequency configured by the core network device.

[0099] In step 503, a positioning signal is transmitted based on carrier frequency information of at least two carrier frequencies and a positioning signal resource.

[0100] In step 504, it is determined whether the positioning signals in at least two carrier frequencies have been disabled, and based on the determination result, it is determined whether to stop transmitting the positioning signals.

[0101] Specifically, in one embodiment of the present disclosure, when a positioning signal at a certain carrier frequency becomes invalid, the invalid positioning signal will cause inaccurate measurement results, and accurate positioning cannot be achieved. In this case, if the carrier frequency still transmits the invalid positioning signal, transmission resources will be wasted, which will affect positioning efficiency. Therefore, in one embodiment of the present disclosure, it is usually necessary to determine whether the positioning signal at each carrier frequency is invalid, so that when it is determined that the positioning signal is invalid, the transmission of the invalid positioning signal is stopped, thereby achieving the purpose of "saving transmission resources and ensuring positioning efficiency".

[0102] In one embodiment of the present disclosure, a method for determining whether the positioning signals of at least two carrier frequencies have become invalid may include a step of determining whether the UE can measure an RS and / or a pathlossReferenceRS indicated by QCL information of the positioning signal at the carrier frequency, and a step of determining that the positioning signal at the carrier frequency has become invalid if the UE cannot measure the RS and / or the pathlossReferenceRS indicated by the QCL information of the positioning signal at the carrier frequency.

[0103] In one embodiment of the present disclosure, the method for stopping the transmission of the positioning signal based on the above-mentioned determination result includes a step of independently determining whether the positioning signal in each carrier frequency has been disabled, and stopping the transmission of the positioning signal in the carrier frequency in which the positioning signal has been disabled, i.e., stopping the transmission of the positioning signal only in the carrier frequency in which the positioning signal has been disabled, and continuing to transmit the positioning signal in the other carrier frequencies in which the positioning signal has not been disabled.

[0104] In another embodiment of the present disclosure, the method for stopping transmission of the positioning signal based on the above determination result includes, when a positioning signal of any carrier frequency is disabled, stopping transmission of the positioning signal on both the disabled carrier frequency and other associated carrier frequencies. The other associated carrier frequencies may include carrier frequencies used to transmit the same positioning signal in aggregate with the disabled carrier frequency, and when at least two carrier frequencies are aggregated to transmit the same positioning signal, one positioning report can be obtained by measuring the positioning signals on the at least two carrier frequencies. Or, the other associated carrier frequencies include carrier frequencies transmitting different positioning signals independently of the disabled carrier frequency, but measurement results of both the other associated carrier frequencies and the disabled carrier frequency are required to calculate the terminal position.

[0105] As described above, in the signal processing method provided by the embodiment of the present disclosure, the user equipment obtains carrier frequency information of at least two carrier frequencies set by the network device, and the carrier frequencies are used to transmit positioning signals, and then the user equipment obtains positioning signal resources corresponding to each carrier frequency set by the network device, and the user equipment transmits positioning signals according to the carrier frequency information and positioning signal resources of the at least two carrier frequencies, and the access network device receives the positioning signals, measures them, obtains a positioning report, and reports them to the core network device. From this, it can be seen that the present disclosure provides a method for setting multi-carrier frequency positioning signals and a method for reporting measurement reports for multi-carrier frequency scenarios, thereby solving the technical problem of "how to set multi-carrier frequency positioning signals and how to report measurement reports".

[0107] In step 601, a positioning signal is received on positioning signal resources in at least two carrier frequencies.

[0108] In one embodiment of the present disclosure, the carrier frequency information of the at least two carrier frequencies and the positioning signal resources corresponding to each carrier frequency may be configured in the access network device by the core network device, or the carrier frequency information of the at least two carrier frequencies and the positioning signal resources corresponding to each carrier frequency may be provided to the core network device by the access network device.

[0109] The positioning signal may also be transmitted by the UE to an access network device.

[0110] In step 602, a positioning signal is measured to obtain a positioning report, and the positioning report is sent to a core network device.

[0111] It should be noted that in one embodiment of the present disclosure, the positioning report obtained by the access network device may be one or more.

[0112] Specifically, in one embodiment of the present disclosure, the at least two carrier frequencies can be aggregated to transmit the same positioning signal, or can be used to transmit different positioning signals independently. When the at least two carrier frequencies are aggregated to transmit the same positioning signal, one positioning report can be obtained by measuring the positioning signals at the at least two carrier frequencies; when the at least two carrier frequencies are used to transmit different positioning signals independently, multiple positioning reports are correspondingly obtained by measuring the positioning signals at each carrier frequency.

[0113] For other detailed explanations regarding steps 601 to 602, refer to the explanations of the above embodiments, and the explanations of the embodiments of the present disclosure will be omitted here.

From this, it can be seen that the present disclosure provides a method for setting multi-carrier frequency positioning signals and a method for reporting measurement reports for multi-carrier frequency scenarios, thereby solving the technical problem of "how to set multi-carrier frequency positioning signals and how to report measurement reports".

[0116] In step 701, capability information reported by a UE is obtained, and the capability information is used to indicate whether the UE supports simultaneous transmission of positioning signals on multiple carrier frequencies.

[0117] In step 702, a positioning signal is received on positioning signal resources on at least two carrier frequencies.

[0118] In one embodiment of the present disclosure, the method for receiving a positioning signal on positioning signal resources in at least two carrier frequencies includes: if the capability information reported by the UE indicates that the UE supports simultaneous transmission of positioning signals on multiple carrier frequencies, the access network device may receive positioning signals simultaneously and / or non-simultaneously on positioning signal resources on at least two carrier frequencies; If the capability information reported by the UE indicates that the UE does not support simultaneous transmission of positioning signals on multiple carrier frequencies, the access network device may include being able to receive positioning signals non-simultaneously on positioning signal resources in at least two carrier frequencies.

[0119] In step 703, measure a positioning signal to obtain a positioning report, and send the positioning report to a core network device.

[0120] For other detailed explanations regarding steps 701 to 703, refer to the explanations of the above embodiments, and the explanations of the embodiments of the present disclosure will be omitted here.

[0121] It should be noted that, in one embodiment of the present disclosure, the above step 701 is selectively performed. Specifically, in one embodiment of the present disclosure, when the access network device receives a positioning signal, the access network device can receive the capability information reported by the UE by performing the above step 701. Also, when the access network device subsequently receives the positioning signal, if the UE's capability of "whether to support simultaneous transmission of positioning signals at multiple carrier frequencies" does not change, the access network device does not need to perform the above step 701 (does not receive the capability information reported by the UE); if the UE's capability of "whether to support simultaneous transmission of positioning signals at multiple carrier frequencies" changes, the UE can perform the above step 701 (i.e., the access network device receives the capability information updated and reported by the UE).

[0122] As described above, in the signal processing method provided by the embodiment of the present disclosure, the user equipment obtains carrier frequency information of at least two carrier frequencies set by the network device, and the carrier frequencies are used to transmit positioning signals, and then the user equipment obtains positioning signal resources corresponding to each carrier frequency set by the network device, and the user equipment transmits positioning signals according to the carrier frequency information and positioning signal resources of the at least two carrier frequencies, and the access network device receives the positioning signals, measures them, obtains a positioning report, and reports them to the core network device.

Specifically, in one embodiment of the present disclosure, when an access network device receives a positioning signal, the access network device can receive the above information reported by the UE by performing the above step 801. Also, when the access network device subsequently receives a positioning signal, if the current corresponding information of the UE (i.e., the phase error group information and / or the timing error group information when the UE currently transmits the positioning signal) does not change compared with the information previously reported by the UE, the access network device does not need to perform the above step 801 (i.e., does not receive the information reported by the UE); if the current corresponding information of the UE changes compared with the information previously reported by the UE, the UE can perform the above step 801 (i.e., the access network device needs to update and receive the information reported by the UE).
