Description

Technical Field

[0001] This disclosure relates to the field of communication technology, and in particular to a signal processing method / apparatus / device and storage medium. Background Technology

[0002] In NR (new radio) systems, to improve positioning accuracy, a positioning method based on carrier phase is typically used to locate devices.

[0003] In related technologies, when using carrier phase-based positioning methods, it is typically necessary to measure and report the integer number of phase cycles (e.g., the integer part of the quotient of transmission distance and carrier frequency wavelength) and the fractional part of the phase that is not an integer cycle (e.g., the fractional part of the quotient of transmission distance and carrier frequency wavelength). However, in these technologies, the integer number of phase cycles in the positioning signal can be ambiguous. To resolve this ambiguity, multiple carrier frequencies with different wavelengths but the same transmission distance are typically used to transmit the positioning signal separately, thus addressing the issue of phase integer number ambiguity.

[0004] Furthermore, after introducing multiple carrier frequencies into the NR system, the question of "how to configure the positioning signals of multiple carrier frequencies and how to report measurement reports" urgently needs to be addressed. Summary of the Invention

[0136] Figure 2b This is a flowchart illustrating a signal processing method provided in an embodiment of the present disclosure. The method is executed by the UE and can be used for uplink positioning, such as... Figure 2b As shown, the method may include the following steps:

[0137] Step 201b: Obtain the carrier frequency information of at least two carrier frequencies configured in the core network equipment.

[0156] Step 203b: Obtain the second part of the parameter information that the core network equipment configures independently for each carrier frequency.

[0157] That is, in one embodiment of this disclosure, the core network device can independently configure a second set of parameter information for positioning signal resources for each carrier frequency.

[0158] In one embodiment of this disclosure, the second part of the parameter information may be parameter information other than the first part of the parameter information in the above-mentioned positioning signal resource parameter information.

[0159] Furthermore, in one embodiment of this disclosure, the second part of the parameter information corresponding to each carrier frequency may be the same.

[0162] For further details regarding steps 201b-204b, please refer to the description of the above embodiments. These embodiments will not be repeated here.

[0163] In summary, in the signal processing method provided in this disclosure, the user equipment (UE) acquires carrier frequency information of at least two carrier frequencies configured by the network device, which are used to transmit positioning signals. Subsequently, the UE also acquires positioning signal resources corresponding to each carrier frequency configured by the network device. Furthermore, the UE can send positioning signals based on the carrier frequency information of the at least two carrier frequencies and the positioning signal resources, so that the access network device receives and measures the positioning signals to obtain a positioning report and reports it to the core network device. Therefore, this disclosure provides a method for configuring positioning signals and reporting measurement reports for multi-carrier scenarios, thereby solving the technical problem of "how to configure positioning signals for multiple carrier frequencies and how to report measurement reports."

[0164] Figure 3 This is a flowchart illustrating a signal processing method provided in an embodiment of the present disclosure. The method is executed by the UE and can be used for uplink positioning, such as... Figure 3 As shown, the method may include the following steps:

[0165] Step 301: Report capability information.

[0166] In one embodiment of this disclosure, the capability information can be used to indicate whether the UE supports the simultaneous transmission of positioning signals on multiple carrier frequencies.

[0167] Furthermore, in one embodiment of this disclosure, the UE can report capability information to at least one of the core network device and the access network device. This allows the core network device to configure carrier frequency information for at least two carrier frequencies and the corresponding positioning signal resources for each carrier frequency to the UE based on the capability information, and / or allows the access network device to receive positioning signals simultaneously and / or not simultaneously based on the capability information.

[0168] Step 302: Obtain the carrier frequency information of at least two carrier frequencies configured in the core network equipment.

[0169] Step 303: Obtain the positioning signal resources corresponding to each carrier frequency configured in the core network equipment.

[0170] In one embodiment of this disclosure, when the aforementioned capability information indicates that the UE supports the 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 positioning signals on multiple carrier frequencies can be transmitted simultaneously or at different times.

[0171] In another embodiment of this disclosure, when the capability information indicates that the UE does not support the 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 so that positioning signals on multiple carrier frequencies can be transmitted at different times.

[0172] Step 304: Send a positioning signal based on the carrier frequency information and positioning signal resources of at least two carrier frequencies.

[0173] In one embodiment of this disclosure, when the aforementioned 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 and / or different time domains on each carrier frequency. The UE needs to transmit positioning signals simultaneously and / or at different times on positioning signal resources on at least two carrier frequencies. In another embodiment of this disclosure, when the aforementioned 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. The UE only needs to transmit positioning signals at different times on positioning signal resources on at least two carrier frequencies.

[0174] It should be noted that, in one embodiment of this disclosure, step 301 is optional. Specifically, in one embodiment of this disclosure, when the UE sends a positioning signal, the UE can report the aforementioned capability information by executing step 301. Furthermore, when the UE subsequently sends a positioning signal, if the UE's capability of "whether it supports simultaneous transmission of positioning signals on multiple carrier frequencies" remains unchanged, the UE may not execute step 301 (i.e., the UE no longer reports this capability information). If the UE's capability of "whether it supports simultaneous transmission of positioning signals on multiple carrier frequencies" changes, the UE may execute step 301 (i.e., the UE needs to update and report this capability information).

[0175] In summary, in the signal processing method provided in this disclosure, the user equipment (UE) acquires carrier frequency information of at least two carrier frequencies configured by the network device, which are used to transmit positioning signals. Subsequently, the UE also acquires positioning signal resources corresponding to each carrier frequency configured by the network device. Furthermore, the UE can send positioning signals based on the carrier frequency information of the at least two carrier frequencies and the positioning signal resources, so that the access network device receives and measures the positioning signals to obtain a positioning report and reports it to the core network device. Therefore, this disclosure provides a method for configuring positioning signals and reporting measurement reports for multi-carrier scenarios, thereby solving the technical problem of "how to configure positioning signals for multiple carrier frequencies and how to report measurement reports."

[0176] Figure 4 This is a flowchart illustrating a signal processing method provided in an embodiment of the present disclosure. The method is executed by the UE and can be used for uplink positioning, such as... Figure 4 As shown, the method may include the following steps:

[0177] Step 401: Obtain the carrier frequency information of at least two carrier frequencies configured in the core network equipment. The carrier frequencies are used to transmit positioning signals.

[0178] Step 402: Obtain the positioning signal resources corresponding to each carrier frequency configured in the core network equipment.

[0179] Step 403: Report information (such as auxiliary information).

[0180] In one embodiment of this disclosure, the information may include at least one of the following:

[0181] The phase error group information when the UE sends the positioning signal includes the ID of the phase error group and / or the error value corresponding to the phase error group.

[0182] The timing error group information when the UE sends the positioning signal includes the ID of the timing error group and / or the error value corresponding to the timing error group.

[0183] Furthermore, the UE can report the above information to the core network equipment so that the core network equipment can consider the impact of this error information when performing positioning calculations based on the positioning report, thus ensuring positioning accuracy. And / or the UE can report the above information to the access network equipment so that the access network equipment can receive and measure the positioning signals sent by the UE based on the above information, ensuring positioning accuracy.

[0184] Step 404: Send a positioning signal based on the carrier frequency information and positioning signal resources of at least two carrier frequencies.

[0185] For further details regarding steps 401-404, please refer to the description of the above embodiments; these embodiments will not be repeated here.

[0186] It should be noted that step 403 is optional. Specifically, in one embodiment of this disclosure, when the UE sends a positioning signal, the UE can report the aforementioned information by executing step 403. Furthermore, when the UE subsequently sends a positioning signal, if the information currently corresponding to the UE (i.e., the phase error group information and / or timing error group information when the UE currently sends the positioning signal) has not changed compared to the information previously reported by the UE, then the UE may not execute step 403 (i.e., no longer report the information); if the information currently corresponding to the UE has changed compared to the information previously reported by the UE, then the UE may execute step 403 (i.e., the UE needs to update and report the information).

[0187] Furthermore, in one embodiment of this disclosure, steps 403 and 404 are not sequential in time, that is, 403 can be before, after, or simultaneously with 404.

[0188] In summary, in the signal processing method provided in this disclosure, the user equipment (UE) acquires carrier frequency information of at least two carrier frequencies configured by the network device, which are used to transmit positioning signals. Subsequently, the UE also acquires positioning signal resources corresponding to each carrier frequency configured by the network device. Furthermore, the UE can send positioning signals based on the carrier frequency information of the at least two carrier frequencies and the positioning signal resources, so that the access network device receives and measures the positioning signals to obtain a positioning report and reports it to the core network device. Therefore, this disclosure provides a method for configuring positioning signals and reporting measurement reports for multi-carrier scenarios, thereby solving the technical problem of "how to configure positioning signals for multiple carrier frequencies and how to report measurement reports."

[0189] Figure 5 This is a flowchart illustrating a signal processing method provided in an embodiment of the present disclosure. The method is executed by the UE and can be used for uplink positioning, such as... Figure 5 As shown, the method may include the following steps:

[0190] Step 501: Obtain the carrier frequency information of at least two carrier frequencies configured in the core network equipment. The carrier frequencies are used to transmit positioning signals.

[0191] Step 502: Obtain the positioning signal resources corresponding to each carrier frequency configured in the core network equipment.

[0192] Step 503: Send a positioning signal based on the carrier frequency information and positioning signal resources of at least two carrier frequencies.

[0193] Step 504: Determine whether the positioning signals on at least two carrier frequencies are invalid, and determine whether to stop transmitting the positioning signals based on the determination results.

[0194] Specifically, in one embodiment of this disclosure, when the positioning signal on a certain carrier frequency fails, the failed positioning signal causes inaccurate measurement results, thus preventing precise positioning. If the carrier frequency continues to transmit the failed positioning signal, transmission resources will be wasted, and positioning efficiency will be affected. Therefore, in one embodiment of this disclosure, it is typically necessary to determine whether the positioning signal on each carrier frequency is failed, so that when a positioning signal is determined to be failed, the transmission of the failed positioning signal is stopped, achieving the goal of "saving transmission resources and ensuring positioning efficiency".

[0195] In one embodiment of this disclosure, the method for determining whether the positioning signals of at least two carrier frequencies are invalid may include: determining whether the UE can measure the RS and / or pathlossReferenceRS indicated by the QCL information of the positioning signal on the carrier frequency; when the UE cannot measure the RS and / or pathlossReferenceRS indicated by the QCL information of the positioning signal on the carrier frequency, determining that the positioning signal on the carrier frequency is invalid.

[0196] Furthermore, in one embodiment of this disclosure, the method for stopping the transmission of the positioning signal based on the judgment result includes: independently determining whether the positioning signal on each carrier frequency is invalid, and stopping the transmission of the positioning signal on the carrier frequency where the positioning signal is invalid. That is, the transmission of the positioning signal is stopped only on the carrier frequency where the positioning signal is invalid, while the positioning signal continues to be transmitted on other carrier frequencies where the positioning signal is not invalid.

[0197] In another embodiment of this disclosure, the method for stopping the transmission of the positioning signal based on the judgment result includes: if the positioning signal of any carrier frequency fails, then the transmission of positioning signals on the failed carrier frequency and other related carrier frequencies is stopped. The other related carrier frequencies may include those aggregated with the failed carrier frequency to transmit the same positioning signal, wherein if at least two carrier frequencies are aggregated to transmit the same positioning signal, a positioning report can be obtained by measuring the positioning signals on at least two carrier frequencies. Other related carrier frequencies include those that transmit different positioning signals independently of the failed carrier frequency, but require the measurement results of other related carrier frequencies and the failed carrier frequency together to calculate the terminal location.

[0198] In summary, in the signal processing method provided in this disclosure, the user equipment (UE) acquires carrier frequency information of at least two carrier frequencies configured by the network device, which are used to transmit positioning signals. Subsequently, the UE also acquires positioning signal resources corresponding to each carrier frequency configured by the network device. Furthermore, the UE can send positioning signals based on the carrier frequency information of the at least two carrier frequencies and the positioning signal resources, so that the access network device receives and measures the positioning signals to obtain a positioning report and reports it to the core network device.

[0202] Furthermore, the location signal can be sent by the UE to the access network device.

[0203] Step 602: Measure the positioning signal to obtain a positioning report, and send the positioning report to the core network equipment.

[0204] It should be noted that, in one embodiment of this disclosure, the location report obtained by the access network device may be one or multiple reports.

[0205] Specifically, in one embodiment of this disclosure, the aforementioned at least two carrier frequencies can be used to aggregate and transmit the same location signal, or to transmit different location signals independently. If the at least two carrier frequencies are used to aggregate and transmit the same location signal, a location report can be obtained by measuring the location signals on the at least two carrier frequencies. If the at least two carrier frequencies are used to transmit different location signals independently, multiple location reports can be obtained by measuring the location signals on each carrier frequency separately.
