[0072]

[0013] As described above, in the signal processing method provided by the embodiments of the present disclosure, the user equipment obtains carrier frequency information of at least two carrier frequencies configured by the network device, and the carrier frequencies are used to transmit positioning signals. Then, the user equipment obtains positioning signal resources corresponding to each carrier frequency configured by the network device. The user equipment transmits positioning signals based on the carrier frequency information of the at least two carrier frequencies and the positioning signal resources, and the access network device receives and measures the positioning signals to obtain positioning reports and report them to the core network device. From this, it can be seen that the present disclosure provides a method for configuring multi-carrier frequency positioning signals and a method for reporting measurement reports for multi-carrier frequency scenarios, thereby solving the technical problems of "how to configure 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 to 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.

[0076] In addition, in one embodiment of the present disclosure, the UE can report capability information to at least one of a core network device and an access network device, and the core network device can configure the UE with carrier frequency information of at least two carrier frequencies and positioning signal resources corresponding to each carrier frequency based on the capability information, and / or the access network device can receive positioning signals simultaneously and / or non-simultaneously based on the capability information.

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

[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 that the positioning signals on the multiple carrier frequencies can be transmitted simultaneously or non-simultaneously.

[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 in 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 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, 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 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 in 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] Note that, 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. Furthermore, 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" remains unchanged, the UE does not need to perform the above step 301 (i.e., the UE does not report this capability information), but 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]

[0013] As described above, in the signal processing method provided by the embodiments of the present disclosure, the user equipment obtains carrier frequency information of at least two carrier frequencies configured by the network device, and the carrier frequencies are used to transmit positioning signals. Then, the user equipment obtains positioning signal resources corresponding to each carrier frequency configured by the network device. The user equipment transmits positioning signals based on the carrier frequency information of the at least two carrier frequencies and the positioning signal resources, and the access network device receives and measures the positioning signals to obtain positioning reports and report them to the core network device. From this, it can be seen that the present disclosure provides a method for configuring multi-carrier frequency positioning signals and a method for reporting measurement reports for multi-carrier frequency scenarios, thereby solving the technical problems of "how to configure 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 to 404.

[0086] In step 401, obtain carrier frequency information of at least two carrier frequencies configured by a core network device, 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 is: 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; The timing error group information may include at least one of: 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 may 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 may specifically report the above information to the access network device so that the access network device can subsequently receive and measure positioning signals 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 descriptions of steps 401 to 404, please refer to the description of the above embodiment, and the description of the embodiment 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 a 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 UE's current corresponding information (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 to 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); but if the UE's current corresponding information changes compared to 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]

[0013] As described above, in the signal processing method provided by the embodiments of the present disclosure, the user equipment obtains carrier frequency information of at least two carrier frequencies configured by the network device, and the carrier frequencies are used to transmit positioning signals. Then, the user equipment obtains positioning signal resources corresponding to each carrier frequency configured by the network device. The user equipment transmits positioning signals based on the carrier frequency information of the at least two carrier frequencies and the positioning signal resources, and the access network device receives and measures the positioning signals to obtain positioning reports and report them to the core network device. From this, it can be seen that the present disclosure provides a method for configuring multi-carrier frequency positioning signals and a method for reporting measurement reports for multi-carrier frequency scenarios, thereby solving the technical problems of "how to configure 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 to 504.

[0097] In step 501, obtain carrier frequency information of at least two carrier frequencies configured by a core network device, 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 on 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, if a positioning signal at a specific carrier frequency becomes invalid, the invalid positioning signal will cause inaccurate measurement results and make accurate positioning impossible. In this case, if the carrier frequency continues to transmit the invalid positioning signal, transmission resources will be wasted, affecting positioning efficiency. Therefore, in one embodiment of the present disclosure, it is generally necessary to determine whether the positioning signal at each carrier frequency has become invalid, and then, if it is determined that the positioning signal has become invalid, stop transmitting the invalid positioning signal, 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 the steps of: determining whether the UE can measure an RS and / or a pathlossReferenceRS indicated by QCL information of the positioning signals at the carrier frequencies; and determining that the positioning signals at the carrier frequencies have become invalid if the UE cannot measure the RS and / or the pathlossReferenceRS indicated by the QCL information of the positioning signals at the carrier frequencies.

[0103] In one embodiment of the present disclosure, the method for stopping transmission of the positioning signal based on the determination result includes a step of independently determining whether the positioning signal at each carrier frequency has been disabled, and stopping transmission of the positioning signal at the carrier frequency at which the positioning signal has been disabled, i.e., stopping transmission of the positioning signal only at the carrier frequency at which the positioning signal has been disabled, and continuing to transmit the positioning signal at the other carrier frequencies at 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 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 positioning signals on at least two carrier frequencies. Alternatively, the other associated carrier frequencies may include carrier frequencies that transmit different positioning signals independently of the disabled carrier frequency, but measurement results on both the other associated carrier frequencies and the disabled carrier frequency are required to calculate the terminal position.

[0105]

[0013] As described above, in the signal processing method provided by the embodiments of the present disclosure, the user equipment obtains carrier frequency information of at least two carrier frequencies configured by the network device, and the carrier frequencies are used to transmit positioning signals. Then, the user equipment obtains positioning signal resources corresponding to each carrier frequency configured by the network device. The user equipment transmits positioning signals based on the carrier frequency information of the at least two carrier frequencies and the positioning signal resources, and the access network device receives and measures the positioning signals to obtain positioning reports and report them to the core network device.

[0106] FIG. 6 is a schematic flowchart of a signal processing method provided by an embodiment of the present disclosure, which is performed by an access network device and can be used for uplink positioning. As shown in FIG. 6, the method can include the following steps 601 to 602.

[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, measure a positioning signal to obtain a positioning report, and send the positioning report to a core network device.

[0111] It should be noted that in one embodiment of the present disclosure, the number of positioning reports 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 independently transmit different positioning signals. 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 independently transmit different positioning signals, multiple positioning reports can be obtained by measuring the positioning signals at each carrier frequency.

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

[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, positioning signals are received on positioning signal resources on at least two carrier frequencies.

[0118] In one embodiment of the present disclosure, the method for receiving positioning signals 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 a step of being able to non-simultaneously receive positioning signals on positioning signal resources on at least two carrier frequencies.

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

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

[0121] Note that, in one embodiment of the present disclosure, the above step 701 is selectively performed. Specifically, in one embodiment of the present disclosure, when an 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. Furthermore, 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" remains unchanged, the access network device does not need to perform the above step 701 (i.e., does not receive the capability information reported by the UE); but 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).
