Description

Technical Field

[0001] The present application relates to the field of communication technology, and in particular to a satellite-based positioning method, positioning system and communication device. Background Art

[0002] In communication systems, such as Figure 1 As shown in the figure, the terminal equipment (UE) communicates with the ground base station, and the ground base station communicates with the core network equipment through optical fiber to realize the communication service of UE. In the event of natural disasters (such as floods, earthquakes, etc.), optical fiber is easily damaged, and the cost of laying optical fiber is high, so backpack base stations come into being. Figure 2 As shown, the backpack base station communicates with the UE, and the backpack base station communicates with the core network equipment via a satellite, thereby realizing communication services for the UE.

[0003] Taking the communication service as a positioning service as an example, there are often situations where the location information of the UE needs to be determined. In the process of determining the location information of the UE, the backpack base station needs to communicate with the core network via satellite. Since the satellite periodically covers the backpack base station, there may be a situation where the backpack base station has no satellite link coverage.

[0088] In this application, "at least one" means one or more, and "plurality" means two or more. "And / or" describes the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone, where A and B can be singular or plural. The character " / " generally indicates that the associated objects before and after are in an "or" relationship. "At least one of the following" or similar expressions refers to any combination of these items, including any combination of single items or plural items. For example, at least one of a, b, or c alone can represent: a, b, c, a and b, a and c, or a, b, and c, where a, b, and c can be single or multiple. In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0089] The directions or positional relationships indicated by terms such as "center", "longitudinal", "lateral", "up", "down", "left", "right", "front", and "back" are based on the directions or positional relationships shown in the accompanying drawings and are only for the convenience of describing the present application and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present application.

[0090] The terms "connected" and "connected" should be understood in a broad sense. For example, the "connected" or "connected" of a circuit structure can refer to not only physical connection, but also electrical connection or signal connection. For example, it can be directly connected, that is, physically connected, or indirectly connected through at least one intermediate element, as long as the circuit is connected, or it can be the internal connection of two elements; signal connection can refer to signal connection through a circuit or through a media medium, such as radio waves. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0091] In conventional technology, there are multiple methods for determining the location information of a UE.

[0092] Method 1: positioning method based on positioning reference signal (PRS), such as Figure 3 As shown, the PRS-based positioning method may include the following steps:

[0093] The location management function (LMF) network element in the core network sends a PRS request to the base station of the serving cell.

[0094] The base station of the serving cell sends the time-frequency resources of the alternative PRS to the LMF.

[0095] The LMF selects all or part of the PRS time-frequency resources from the candidate PRS time-frequency resources, and notifies the UE, the base station of the serving cell, and the base station of the neighboring cell of all or part of the PRS time-frequency resources respectively.

[0096] The base station of the serving cell and the base station of the neighboring cell respectively send PRS to the UE at the location indicated by the time-frequency resources notified by the LMF.

[0097] The UE measures the two PRSs respectively, and obtains the difference between the reception time of the PRS sent by the base station of the serving cell and the reception time of the PRS sent by the base station of the neighboring cell.

[0098] The UE sends the difference to the LMF.

[0099] The LMF determines the location information of the UE based on the difference.

[0100] Method 2: positioning method based on sounding reference signal (SRS), such as Figure 4 As shown, the SRS-based positioning method may include the following steps:

[0101] The LMF network element in the core network sends an SRS request to the base station of the serving cell.

[0102] The base station of the serving cell sends the time-frequency resources of the alternative SRS to the LMF.

[0103] The LMF selects all or part of the SRS time-frequency resources from the candidate SRS time-frequency resources, and notifies the UE, the base station of the serving cell, and the base station of the neighboring cell of all or part of the SRS time-frequency resources respectively.

[0104] The UE sends SRS to the base station of the serving cell and the base station of the neighboring cell respectively at the location indicated by the time-frequency resources notified by the LMF.

[0105] The base station of the serving cell measures the SRS to obtain a receiving time, and the base station of the neighboring cell measures the SRS to obtain another receiving time.

[0106] The base station of the serving cell sends a receiving time to the LMF.

[0107] The base station of the neighboring cell sends another receiving time to the LMF.

[0108] LMF determines the UE's location information based on the two reception times.

[0109] In method 1, the UE needs to measure the PRS sent by the base station of the serving cell and the PRS sent by the base station of the neighboring cell to determine the location information of the UE. Therefore, the UE needs to have high measurement accuracy.

[0110] In method 2, the UE needs to send SRS to the base station of the serving cell and the base station of the neighboring cell respectively. In this way, the UE consumes more power when sending the SRS. Therefore, the UE needs to have a higher battery life.

[0111] However, the base stations in the above two methods are not applicable to backpack base stations. Because there is a situation where there is no satellite link coverage for backpack base stations, that is, backpack base stations do not always have satellite link coverage. When there is no satellite link coverage, the backpack base station cannot communicate with the core network via satellite. Therefore, when the above method 1 is adopted, the UE will not be able to send the difference to the LMF through the backpack base station. When the above method 2 is adopted, the backpack base station of the service cell cannot send a receiving time to the LMF, and the backpack base station of the neighboring cell cannot send another receiving time to the LMF. In this way, the above methods 1 and 2 will not be able to determine the location information of the UE.

[0112] If the backpack base station is covered by a satellite link, the backpack base station will communicate with the core network via satellite. In this way, although the above method 1 or method 2 can determine the location information of the UE, the positioning process will be longer. In addition, especially when the UE moves, since the information fed back to the LMF is not timely enough, the location information of the UE determined by the above method 1 or method 2 will be inaccurate, which will also make it impossible to determine the location information of the UE.

[0113] Based on the above problems, the present application provides a satellite-based positioning method, positioning system, communication device, computer-readable storage medium and chip, which can fully consider the factor that the network equipment is covered by satellite links, determine the time and frequency resources of positioning-related reference signals covered by satellite links, and thus accurately and quickly determine the location information of the terminal device.

[0114] The positioning related reference signal may be a PRS, an SRS, or other types of signals.

[0115] See also Figure 5 , Figure 5 FIG. 1 shows a schematic diagram of the structure of a positioning system provided by an embodiment of the present application. Figure 5 As shown, the positioning system of the present application may include: network equipment 11, network equipment 12, satellite 13, terminal equipment 14 and core network equipment 15.

[0116] The network device 11 can communicate with the terminal device 14, and the network device 11 can also communicate with the core network device 15 through the satellite 13. The network device 12 can communicate with the terminal device 14, and the network device 12 can also communicate with the core network device 15 through the satellite 13. The satellite 13 communicating with the network device 11 and the satellite 13 communicating with the network device 12 can be the same satellite or different satellites.

[0117] The network device 12 may include one or more. The satellite 13 may include one or more. The terminal device 14 may include one or more. The core network device 15 may include one or more. The network device 11 is different from the network device 12. The network device 11 is a device that currently provides communication services for the terminal device 14. The communication services may include positioning services, signal measurement services, etc. The cell where the user terminal 14 is currently located is the serving cell, and the network device 11 may also be referred to as the network device 11 of the serving cell. The cell adjacent to the serving cell is a neighboring cell, and the network device 12 may also be referred to as the network device 12 of the neighboring cell.

[0118] The network device 11 or the network device 12 may be a base station, an access point, or an access network device, or may refer to a device in the access network that communicates with the wireless terminal through one or more sectors on the air interface. The network device may be used to convert received air frames to and from IP packets, and serve as a router between the wireless terminal and the rest of the access network, wherein the rest of the access network may include an Internet Protocol (IP) network. The network device may also coordinate the attribute management of the air interface.

[0126] Scene 1

[0127] See also Figure 6 , Figure 6A signaling interaction diagram of a satellite-based positioning method provided in an embodiment of the present application is shown.

[0128] like Figure 6 As shown, the satellite-based positioning method of the present application may include:

[0129] S101. A first communication device sends a first request to a second communication device.

[0130] Correspondingly, the second communication device receives the first request sent by the first communication device.

[0131] The first request is used to request the location information of the third communication device. The first request may indicate the type of the positioning related reference signal. That is, the first request may indicate that the positioning related reference signal is a PRS, or a signal related to the PRS.

[0132] The location information of the third communication device may be an absolute location or a relative location, etc. For example, the absolute location may be longitude and latitude based on a world coordinate system, and the relative location may be location information with the first communication device and the second communication device as reference points.

[0133] Based on this, when the location information of the third communication device needs to be determined, the first communication device can send a first request to the second communication device, so that the second communication device knows that the first communication device requests to determine the location information of the third communication device by transmitting PRS.

[0134] S102: The second communication device sends first information to the first communication device.

[0135] Correspondingly, the first communication device receives the first information sent by the second communication device.

[0136] The first information is used to indicate a first time-frequency resource of the PRS, and the first time-frequency resource of the PRS is related to a first time period.

[0137] It should be noted that the time-frequency resources of PRS in this application refer to time domain resources and frequency domain resources. Among them, the time domain resources are used to indicate one or more transmission moments, one or more transmission time periods and other information, and the PRS can be transmitted at one or more transmission moments or in one or more transmission time periods indicated by the time-frequency resources. The frequency domain resources are used to indicate one or more sub-bands and other information, and the PRS can be transmitted on the sub-bands indicated by the frequency domain resources.

[0138] The first time-frequency resource of the PRS refers to information such as one or more transmission time instants, one or more transmission time periods, or one or more sub-frequency bands of the PRS.

[0139] Among them, the first time period is the time period in which the second communication device is covered by the satellite link. That is to say, the second communication device is covered by the satellite link in the first time period, so that the second communication device can communicate with the core network device through the satellite in the first time period. Since the satellite periodically covers the second communication device. Therefore, the time period in which the satellite link covers the second communication device is periodic, and the time period in which the satellite link covers the second communication device includes multiple cycles. In this way, the first time period can be any one cycle or all cycles. When the first time period is any one cycle, the first time period is determined, and the time period in which the satellite link covers the second communication device is also determined. In other words, the time period in which the satellite link covers the second communication device can be derived based on the first time period. The first time period can be determined based on the ephemeris information of the satellite, and the ephemeris information can be pre-stored in the second communication device, can be stored in the satellite, or can be stored in the satellite network management platform.

[0140] Based on this, the second communication device can determine the first information.

[0141] In some examples, the second communication device may determine that the first time-frequency resource of the PRS is an available time-frequency resource of the PRS in the first time period. Thus, the second communication device may determine that the first information is used to indicate the available first time-frequency resource of the PRS.

[0142] In other examples, considering the time delay of PRS transmission, the time-frequency resources of PRS in the time period when the satellite link covers the second communication device cannot be fully used to locate the third communication device. Therefore, the second communication device can screen the time-frequency resources of PRS in the time period when the satellite link covers the second communication device to obtain the available time-frequency resources 1 of PRS. Among them, the time-frequency resource 1 can indicate one or more sending time moments, or one or more sending time periods.

[0143] The available PRS refers to a PRS that can be used to locate the third communication device.

[0144] It can be seen that the second communication device can rationalize the time-frequency resources of the PRS used to locate the third communication device in combination with the actual satellite coverage of the second communication device and the objective delay effect of the PRS. Thus, the first communication device can determine that the first information is used to indicate the available PRS time-frequency resource 1. In addition, the time-frequency resource 1 here can be the second time-frequency resource mentioned later, or it can be other time-frequency resources.

[0145] In summary, in response to the first request, the second communication device can determine the first information. Thus, the second communication device can send the first information to the first communication device, so that the first communication device knows that it is necessary to consider in which time period or time periods the second communication device has satellite link coverage to determine the time-frequency resources of the PRS used to locate the third communication device.

[0146] S1031. The first communication device sends second information to the second communication device.

[0147] Correspondingly, the second communication device receives the second information sent by the first communication device.

[0148] S1032. The first communication device sends second information to the third communication device.

[0149] Correspondingly, the third communication device receives the second information sent by the first communication device.

[0150] S1033. The first communication device sends second information to the fourth communication device.

[0151] Correspondingly, the fourth communication device receives the second information sent by the first communication device.

[0152] It should be noted that there is no temporal order between the above S1031 - S1033 , and S1031 - S1033 can be executed simultaneously or sequentially.

[0153] The second information is used to indicate the second time-frequency resource of the available PRS, the second information is determined according to the first information and the first time period, the second information is used to determine the location information of the third communication device, and the second communication device is different from the fourth communication device. In other words, the second time-frequency resource of the PRS refers to information such as one or more transmission moments, one or more transmission time periods, or one or more sub-bands of the available PRS.

[0154] It should be noted that when the second time-frequency resource of the PRS indicates a transmission time, the first communication device, the second communication device, the third communication device and the fourth communication device need to know the transmission time. In addition, the second communication device, the third communication device and the fourth communication device can simultaneously transmit the PRS according to the transmission time.

[0155] When the second time-frequency resource of the PRS indicates multiple transmission time instants, the first communication device, the second communication device, the third communication device, and the fourth communication device need to know the multiple transmission time instants. In addition, the second communication device, the third communication device, and the fourth communication device can simultaneously transmit the PRS according to each of the multiple transmission time instants.

[0156] Based on this, the first communication device can determine the second information.

[0157] In some examples, considering the time delay of PRS transmission, the time-frequency resources of PRS in the time period when the satellite link covers the second communication device cannot be fully used to locate the third communication device. Therefore, when the first communication device learns that the first information is used to indicate that PRS is available in the first time period or time-frequency resource 1, the first communication device can screen the time-frequency resources of PRS in the time period when the satellite link covers the second communication device according to the first information and the first time period, and obtain the available second time-frequency resources of PRS.

[0158] It can be seen that the first communication device can rationalize the time-frequency resources of the PRS used to locate the third communication device by combining the actual satellite coverage of the second communication device and the objective delay effect of the PRS. Thus, the first communication device can determine the second information.

[0159] In other examples, if the second communication device has taken into account the influence of the delay in the transmission of the PRS, the second communication device has screened the time-frequency resources of the PRS in the time period when the satellite link covers the second communication device according to the first information and the first time period. In this way, the available time-frequency resource 1 of the PRS obtained by the second communication device is the available second time-frequency resource of the PRS.

[0160] It can be seen that the second communication device can indicate the available second time-frequency resource of the PRS to the first communication device through the first information. Thus, the first communication device can determine that the second information includes the first information. In addition, the second time-frequency resource can be determined by the first communication device, or by the second communication device, or by the first communication device and the second communication device, and this application does not limit this. The first communication device and the second communication device can negotiate in advance who will determine it.

[0161] Based on this, the first communication device can send the second information to the second communication device, the third communication device and the fourth communication device respectively, so that the second communication device, the third communication device and the fourth communication device can know which PRS time-frequency resources can be used to locate the third communication device during the time period when the satellite link covers the second communication device, thereby facilitating the second communication device and the fourth communication device to simultaneously send PRS according to the second information, and correspondingly, the third communication device can respectively receive PRS according to the second information.

[0162] In some examples, after the second communication device, the third communication device, and the fourth communication device receive the second information, the satellite-based positioning method of the present application also includes: S1041-S105.

[0163] Among them, S1041-S105 are optional steps.

[0164] S1041. The second communication device sends a first PRS to the third communication device according to the second information.

[0165] Correspondingly, the third communication device receives the first PRS sent by the second communication device according to the second information.

[0166] S1042: The fourth communication device sends a second PRS to the third communication device according to the second information.

[0167] Correspondingly, the third communication device receives the second PRS sent by the fourth communication device according to the second information.

[0168] It should be noted that the above S1041-S1042 need to be executed simultaneously.

[0169] The sending time of the first PRS and the second PRS are consistent.

[0170] The number of the first PRS or the second PRS is one or more, and the number of the first PRS and the second PRS is the same. The first PRS and the second PRS are in one-to-one correspondence, and the corresponding first PRS and the second PRS are sent at the same time.

[0171] When the number of the first PRS is one and the number of the second PRS is one, the sending time of the first PRS is the same as the sending time of the second PRS.

[0172] When the number of the second PRS is plural, the multiple first PRSs correspond to the multiple second PRSs one by one, and the sending time of a corresponding first PRS and a corresponding second PRS is the same.

[0173] When the number of the first PRS is one and the number of the second PRS is one, the second communication device and the fourth communication device may determine a transmission time from one or more transmission times indicated by the second time-frequency resource according to the second information. Thus, the second communication device and the fourth communication device may simultaneously and respectively transmit the first PRS and the second PRS to the third communication device at the transmission time.

[0174] Correspondingly, the third communication device can obtain the transmission time of the first PRS and the second PRS according to the second information, so that the third communication device can be prepared to receive the PRS. Thus, the third communication device can determine the reception time period of the PRS according to the same transmission time of the first PRS and the second PRS.

[0175] In some examples, the PRS reception time period may be a certain time period starting from the same transmission time of the first PRS and the second PRS. Alternatively, the PRS reception time period may be a certain time period after the same transmission time of the first PRS and the second PRS.

[0176] In addition, the PRS reception time period may also be replaced by the PRS reception start time and total reception duration, or the PRS reception end time and total reception duration, or the PRS reception start time, reception end time and total reception duration.

[0177] In this way, the third communication device can receive the first PRS from the second communication device and the second PRS from the fourth communication device within the PRS reception time period.

[0178] When the number of the first PRS is multiple and the number of the second PRS is multiple, the second communication device and the fourth communication device can determine multiple transmission times from one or more transmission times indicated by the second time-frequency resource according to the second information. Thus, for each of the multiple transmission times, the second communication device and the fourth communication device can simultaneously send a corresponding first PRS and a corresponding second PRS to the third communication device at each transmission time. Correspondingly, the third communication device can obtain multiple transmission times according to the second information, so that the third communication device can be prepared to receive the PRS. Thus, the third communication device can determine the reception time period of the PRS according to the multiple transmission times.

[0179] In some examples, the PRS reception time period may be a certain time period starting from the earliest time of the multiple transmission time periods. Alternatively, the PRS reception time period may be a certain time period after the earliest time of the multiple transmission time periods.

[0180] In addition, the PRS reception time period may also be replaced by the PRS reception start time and total reception duration, or the PRS reception end time and total reception duration, or the PRS reception start time, reception end time and total reception duration.

[0181] In this way, the third communication device can receive multiple first PRSs from the second communication device and multiple second PRSs from the fourth communication device within the PRS reception time period.

[0182] S105. The third communication device sends third information to the first communication device.

[0183] Correspondingly, the first communication device receives the third information sent by the third communication device.

[0184] The third information is used to determine the location information of the third communication device, and the third information is determined by the third communication device according to the first PRS and the second PRS.

[0185] Since the transmission time of the PRS is affected by the distance, the second communication device and the fourth communication device are usually arranged at different locations. Therefore, the distance between the second communication device and the third communication device is different from the distance between the fourth communication device and the third communication device.

[0186] Based on the above description, the reception time of the first PRS is different from the reception time of the second PRS. The reception time of the PRS here refers to the time when the third communication device receives the PRS. Therefore, the third communication device can determine the difference value based on the reception time of the first PRS and the reception time of the second PRS. The third communication device can determine the third information based on the difference value.

[0187] When the number of the first PRS is one and the number of the second PRS is one, the third communication device determines a difference according to the reception time of the first PRS and the reception time of the second PRS. Thus, the third communication device can determine the third information according to the difference.

[0188] It can be seen that the above implementation manner can save the computing resources of the third communication device for determining the location information of the third communication device according to the third information.

[0189] When the number of the first PRS is multiple and the number of the second PRS is multiple, for each pair of the first PRS and the second PRS in the multiple first PRSs and the multiple second PRSs, the third communication device determines a difference value according to the reception time of the first PRS in each pair and the reception time of the corresponding second PRS. In this way, the third communication device can determine multiple differences. Thus, the third communication device can determine the third information according to the multiple differences.

[0190] It can be seen that the above implementation manner can improve the accuracy of the third communication device determining the location information of the third communication device according to the third information.

[0191] The present application does not limit the specific implementation of the third information. For example, the third information carries the location information of the third communication device.

[0192] Thus, the third communication device can send the third information to the first communication device through the second communication device or the fourth communication device. The first communication device can then determine the location information of the third communication device according to the third information.

[0193] The satellite-based positioning method provided in the present application sends a first request to a second communication device through a first communication device, and the first request is used to request the location information of a third communication device, so that the second communication device learns that the first communication device requests to determine the location information of the third communication device by transmitting PRS. The second communication device responds to the first request and determines the first information, and the second communication device sends the first information to the first communication device, so that the first communication device can learn from the first information whether the second communication device needs to be considered whether it has satellite link coverage. The first communication device can determine the second information, and the first communication device can send the second information to the second communication device, the third communication device and the fourth communication device respectively, and the second information is used to indicate the second time-frequency resource of the available PRS, which can make the second communication device, the third communication device and the fourth communication device Which or which PRS time-frequency resources can be used to locate the third communication device. Thus, it is helpful to quickly and accurately determine the location information of the third communication device, avoid the phenomenon that the third communication device cannot be located in time due to the second communication device having no satellite link coverage, and also avoid the phenomenon that the third communication device may move during the positioning process, and the information fed back to the first communication device is not timely enough, and the third communication device cannot be accurately located.

[0194] In this way, the second communication device sends the first PRS to the third communication device according to the second information, the fourth communication device sends the second PRS to the third communication device according to the second information, and the third communication device receives the first PRS and the second PRS respectively according to the second information. Thus, the third communication device determines the third information according to the first PRS and the second PRS. The third communication device sends the third information to the first communication device through the second communication device, and the first communication device can determine the location information of the third communication device according to the third information. Thus, the positioning of the third communication device is achieved.

[0195] Based on the description of the above embodiment, the time period indicated by the second time-frequency resource is the second time period. When the number of PRS transmission moments is one, the second time period refers to a period of time including the one transmission moment of the PRS. When the number of PRS transmission moments is multiple, the second time period refers to a period of time including the multiple transmission moments of the PRS.

[0196] The second time period may be represented in a variety of ways.

[0197] As a feasible representation, the second time period includes a third time period and a fourth time period, the third time period is a time period before the first time period, the fourth time period is a partial time period in the first time period, and the third time period is connected to the fourth time period.

[0198] Next, combine Figure 7 , the second time period is explained exemplarily.

[0199] Figure 7 In the example, the first time period is recorded as the time period from T1 to T2, the third time period is recorded as the time period from T3 to T1, and the fourth time period is recorded as the time period from T1 to T4.

[0200] like Figure 7 As shown, due to the delay in the transmission of PRS, after the PRS in the T4 to T2 time period is transmitted, the reception time of the PRS may fall outside the T1 to T2 time period, and the second communication device has no satellite link coverage outside the T1 to T2 time period. Therefore, the time-frequency resources of the PRS in the T4 to T2 time period cannot be used to locate the third communication device. Based on this, the first communication device and / or the second communication device can exclude the T4 to T2 time period from the T1 to T2 time period and retain the T1 to T4 time period.

[0201] Furthermore, since there is a time delay in the transmission of the PRS, after the PRS in the time period from T3 to T1 is transmitted, the reception time of the PRS may fall within the time period from T1 to T2, and the second communication device is covered by the satellite link within the time period from T1 to T2. Therefore, the time-frequency resources of the PRS in the time period from T3 to T1 can be used to locate the third communication device.

[0202] In summary, the first communication device and / or the second communication device may determine that the second time period is the time period from T3 to T4. Thus, the first communication device and / or the second communication device may select the time-frequency resources of the PRS from the time period from T3 to T4, which can improve the utilization rate of the time-frequency resources of the PRS and also improve the accuracy of positioning.

[0203] As another feasible representation, the second time period is all or part of the first time period except the time period from T4 to T2. In some examples, the second time period is the fourth time period mentioned above. Alternatively, the second time period is part of the fourth time period mentioned above.

[0204] For example, combining Figure 7 , the fourth time period is recorded as the time period from T1 to T4. Based on the description of a feasible representation method mentioned above, the first communication device and / or the second communication device may determine that the second time period is the time period from T1 to T4. Thus, the first communication device and / or the second communication device may select the time-frequency resources of the PRS from the time period from T1 to T4, which can improve the accuracy of positioning.

[0205] Based on the description of the above embodiments, the first communication device and / or the second communication device may adopt multiple implementation methods to determine the second time period, that is, one or more sending times of the PRS, according to the first information.

[0206] In some examples, the first information may carry a first time threshold value and a second time threshold value, the first time threshold value is used to indicate that the first time-frequency resource of the PRS is available in a third time period, and the second time threshold value is used to indicate that the first time-frequency resource of the PRS is unavailable in a fifth time period, the third time period is the time period before the first time period, the fifth time period is the other time period in the first time period except the fourth time period, the fourth time period is a partial time period in the first time period, and the third time period is connected to the fourth time period.

[0207] The first time threshold value and the second time threshold value may be the same or different in size. The size of the first time threshold value and the second time threshold value is related to the delay of PRS transmission.

[0208] The length of the third time period may be equal to the first time threshold, and the length of the fifth time period may be equal to the second time threshold.

[0209] Combination Figure 7 The first time period is recorded as the time period from T1 to T2, the third time period is recorded as the time period from T3 to T1, the fourth time period is recorded as the time period from T1 to T4, and the fifth time period is recorded as the time period from T4 to T2.

[0210] Therefore, the first communication device and / or the second communication device may determine that the second time period is the time period from T3 to T4 according to the first information.

[0211] In addition, the first information may not carry the first time threshold value and the second time threshold value.

[0212] In some examples, the first communication device and / or the second communication device may store the first time threshold and the second time threshold in advance. In this way, the first communication device and / or the second communication device may determine that the second time period is the time period from T3 to T4 according to the first information, the first time threshold and the second time threshold.

[0213] In some other examples, the first communication device and / or the second communication device may store the second time threshold in advance. In this way, the first communication device and / or the second communication device may determine that the second time period is the time period T1 to T4 according to the first information and the second time threshold. Thus, the first communication device and / or the second communication device may determine the second time-frequency resource of the PRS.

[0214] Scene 2

[0215] See also Figure 8 , Figure 8 A signaling interaction diagram of a satellite-based positioning method provided in an embodiment of the present application is shown.

[0216] like Figure 8As shown, the satellite-based positioning method of the present application may include:

[0217] S201. A first communication device sends a first request to a second communication device.

[0218] Correspondingly, the second communication device receives the first request sent by the first communication device.

[0219] The first request is used to request the location information of the third communication device. The first request may indicate the type of the positioning related reference signal. That is, the first request may indicate that the positioning related reference signal is SRS, or a signal related to SRS.

[0220] The location information of the third communication device may be an absolute location or a relative location, etc. For example, the absolute location may be longitude and latitude based on a world coordinate system, and the relative location may be location information with the first communication device and the second communication device as reference points.

[0221] Based on this, when the location information of the third communication device needs to be determined, the first communication device can send a first request to the second communication device, so that the second communication device knows that the first communication device requests to determine the location information of the third communication device by transmitting SRS.

[0222] S202: The second communication device sends first information to the first communication device.

[0223] Correspondingly, the first communication device receives the first information sent by the second communication device.

[0224] The first information is used to indicate a first time-frequency resource of the SRS, and the first time-frequency resource of the SRS is related to a first time period.

[0225] It should be noted that the time-frequency resources of SRS in this application refer to time domain resources and frequency domain resources. Among them, the time domain resources are used to indicate one or more transmission times, one or more transmission time periods and other information, and the SRS can be transmitted at one or more transmission times or in one or more transmission time periods indicated by the time-frequency resources. The frequency domain resources are used to indicate one or more sub-bands and other information, and the SRS can be transmitted on the sub-bands indicated by the frequency domain resources.

[0226] The first time-frequency resource of the SRS refers to information such as one or more transmission time instants, one or more transmission time periods, or one or more sub-frequency bands of the SRS.

[0227] Among them, the first time period is the time period in which the second communication device is covered by the satellite link. That is to say, the second communication device is covered by the satellite link in the first time period, so that the second communication device can communicate with the core network device through the satellite in the first time period. Since the satellite periodically covers the second communication device. Therefore, the time period in which the satellite link covers the second communication device is periodic, and the time period in which the satellite link covers the second communication device includes multiple cycles. In this way, the first time period can be any one cycle or all cycles. When the first time period is any one cycle, the first time period is determined, and the time period in which the satellite link covers the second communication device is also determined. In other words, the time period in which the satellite link covers the second communication device can be derived based on the first time period. The first time period can be determined based on the ephemeris information of the satellite, and the ephemeris information can be pre-stored in the second communication device, can be stored in the satellite, or can be stored in the satellite network management platform.

[0228] Based on this, the second communication device can determine the first information.

[0229] In some examples, the second communication device may determine that the first time-frequency resource of the SRS is a time-frequency resource of the SRS available in the first time period. Thus, the second communication device may determine that the first information is used to indicate the first time-frequency resource of the available SRS.

[0230] In other examples, considering the time delay of SRS transmission, the time-frequency resources of SRS in the time period when the satellite link covers the second communication device cannot be fully used to locate the third communication device. Therefore, the second communication device can screen the time-frequency resources of SRS in the time period when the satellite link covers the second communication device to obtain the available time-frequency resources 1 of SRS. Among them, the time-frequency resource 1 can indicate one or more sending time moments, or one or more sending time periods.

[0231] The available SRS refers to an SRS that can be used to locate the third communication device.

[0232] It can be seen that the second communication device can rationalize the time-frequency resources of the SRS used to locate the third communication device in combination with the actual satellite coverage of the second communication device and the objective delay effect of the SRS. Thus, the first communication device can determine that the first information is used to indicate the time-frequency resource 1 of the available SRS. In addition, the time-frequency resource 1 here is the second time-frequency resource mentioned later, and can also be other time-frequency resources.

[0233] In summary, in response to the first request, the second communication device can determine the first information. Thus, the second communication device can send the first information to the first communication device, so that the first communication device knows that it needs to consider in which time period or time periods the second communication device and the fourth communication device are simultaneously covered by the satellite link to determine the time-frequency resources of the SRS used to locate the third communication device.

[0234] S203: The first communication device sends second information to the fourth communication device.

[0235] Correspondingly, the fourth communication device receives the second information sent by the first communication device.

[0236] The second information is used to indicate the second time-frequency resource of the SRS available to the second communication device, the second information is determined based on the first information and the first time period, and the fourth communication device is different from the second communication device. In other words, the second time-frequency resource of the SRS refers to one or more transmission moments, one or more transmission time periods, or one or more sub-bands of the SRS available to the second communication device.

[0237] After receiving the first information, the first communication device may determine the second information.

[0238] In some examples, considering the time delay of SRS transmission, the time-frequency resources of SRS in the time period when the satellite link covers the second communication device cannot be fully used to locate the third communication device. Therefore, when the first communication device learns that the first information is used to indicate that SRS is available in the first time period or time-frequency resource 1, the first communication device can screen the time-frequency resources of SRS in the time period when the satellite link covers the second communication device according to the first information and the first time period to obtain the second time-frequency resources.

[0239] It can be seen that the first communication device can rationalize the time-frequency resources of the SRS used to locate the third communication device in combination with the actual satellite coverage of the second communication device and the objective delay effect of the SRS. Thus, the first communication device can determine the second information without considering whether the second communication device has considered the transmission delay of the SRS.

[0240] In other examples, if the second communication device has taken into account the impact of time delay in SRS transmission, the second communication device has screened the SRS within the time period when the satellite link covers the second communication device based on the first information and the first time period. In this way, the time-frequency resource 1 corresponding to the available SRS obtained by the second communication device is the second time-frequency resource.

[0241] It can be seen that the second communication device can indicate the available second time-frequency resource of SRS to the first communication device through the first information. Therefore, the first communication device can determine that the second information includes the first information, which fully combines the transmission delay of SRS considered by the second communication device and reduces the use of resources.

[0242] In addition, the second time-frequency resource may be determined by the first communication device, or by the second communication device, or by the first communication device and the second communication device, which is not limited in this application. The first communication device and the second communication device may negotiate in advance who will determine the resource.

[0243] Since the first communication device requests to locate the third communication device by transmitting SRS, the first communication device needs to consider not only whether the second communication device is covered by the satellite link, but also whether the fourth communication device is covered by the satellite link.

[0244] Based on this, the first communication device sends the second information to the fourth communication device, so that the fourth communication device can obtain the second time-frequency resources of the SRS available to the second communication device, and also enable the fourth communication device to determine which SRS time-frequency resources can be used simultaneously to locate the third communication device during the time period when the second communication device and the fourth communication device are covered by the satellite link.

[0245] S204: The fourth communication device sends third information to the first communication device.

[0246] Correspondingly, the first communication device receives the third information sent by the fourth communication device.

[0247] Among them, the third information is used to indicate the third time-frequency resource of the SRS that is commonly used by the second communication device and the fourth communication device, and the third information is determined by the fourth communication device based on the second information and the fourth time period. In other words, the third time-frequency resource of the SRS refers to one or more transmission times, one or more transmission time periods, or one or more sub-bands of the PRS that are commonly used by the second communication device and the fourth communication device. For ease of description, in this application, the third time-frequency resource of the SRS that is commonly used by the second communication device and the fourth communication device may be referred to as the third time-frequency resource of the commonly used SRS for description.

[0248] It should be noted that when the third time-frequency resource of the commonly available SRS indicates a transmission time, the first communication device, the second communication device, the third communication device and the fourth communication device need to know the transmission time. In addition, the second communication device, the third communication device and the fourth communication device can simultaneously transmit the SRS according to the transmission time.

[0249] When the third time-frequency resource of the commonly available SRS indicates multiple transmission time instants, the first communication device, the second communication device, the third communication device, and the fourth communication device need to know the multiple transmission time instants. In addition, the second communication device, the third communication device, and the fourth communication device can simultaneously transmit the SRS according to each of the multiple transmission time instants.

[0250] Among them, the fourth time period is a time period in which the fourth communication device is covered by a satellite link. That is to say, the fourth communication device is covered by a satellite link in the fourth time period, so that the fourth communication device can communicate with the core network device through the satellite in the fourth time period. Since the satellite periodically covers the fourth communication device. Therefore, the time period in which the satellite link covers the fourth communication device is periodic, and the time period in which the satellite link covers the fourth communication device includes multiple cycles. In this way, the fourth time period can be any one cycle or all cycles. When the fourth time period is any one cycle, the fourth time period is determined, and the time period in which the satellite link covers the fourth communication device is also determined. The fourth time period can be determined based on the ephemeris information of the satellite, and the ephemeris information can be pre-stored in the fourth communication device, can be stored in the satellite, or can be stored in the satellite network management platform.

[0251] The fourth communication device may determine the third time-frequency resource of the commonly available SRS in multiple ways.

[0252] In some examples, the fourth communication device may determine the overlapping time-frequency resources of the time-frequency resources in the fourth time period and the second time-frequency resources as the third time-frequency resources of the commonly available SRS.

[0253] It can be seen that the fourth communication device can rationalize the time-frequency resources of the SRS used for positioning the third communication device by combining factors such as the actual coverage of the second communication device and the actual coverage of the fourth communication device.

[0254] In other examples, considering the time delay of SRS transmission, the time-frequency resources of SRS in the time period when the satellite link covers the fourth communication device cannot be fully used to locate the third communication device. Therefore, the fourth communication device can screen the time-frequency resources of SRS in the time period when the satellite link covers the fourth communication device to obtain the available time-frequency resources 2 corresponding to the SRS. Thus, the fourth communication device can determine the overlapping time-frequency resources of time-frequency resource 2 and the second time-frequency resource as the third time-frequency resource of the commonly available SRS.

[0255] It can be seen that the fourth communication device can rationalize the time-frequency resources of the SRS used to locate the third communication device by combining factors such as the actual coverage of the second communication device, the actual coverage of the fourth communication device, and the objective delay impact of the SRS.

[0256] Based on the above description, the fourth communication device can determine the third information based on the third time-frequency resources of the commonly available SRS. Thus, the fourth communication device can send the third information to the first communication device, so that the first communication device can know which SRS time-frequency resources are commonly available to the second communication device and the fourth communication device.

[0257] S2051. The first communication device sends third information to the second communication device.

[0258] Correspondingly, the second communication device receives the third information sent by the first communication device.

[0259] S2052: The first communication device sends third information to the third communication device.

[0260] Correspondingly, the third communication device receives the third information sent by the first communication device.

[0261] S2053. The first communication device sends third information to the fourth communication device.

[0262] Correspondingly, the fourth communication device receives the third information sent by the first communication device.

[0263] It should be noted that there is no temporal order between the above S2051-S2053, and S2051-S2053 can be executed simultaneously or sequentially.

[0264] The third information is used to determine the location information of the third communication device.

[0265] Based on this, the first communication device sends the third information to the second communication device, the third communication device and the fourth communication device respectively, so that the second communication device, the third communication device and the fourth communication device can know which SRS time-frequency resources can be used to locate the third communication device, thereby facilitating the third communication device to send SRS to the second communication device and the fourth communication device respectively according to the third information. Correspondingly, the second communication device can receive the SRS sent by the third communication device according to the third information, and the fourth communication device can receive the SRS sent by the third communication device according to the third information.

[0266] In some examples, after the second communication device, the third communication device, and the fourth communication device receive the third information, the satellite-based positioning method of the present application also includes: S2061-S2072.

[0267] Among them, S2061-S2072 are optional steps.

[0268] S2061. The third communication device sends a first SRS to the second communication device according to the third information.

[0269] Correspondingly, the second communication device receives the first SRS sent by the third communication device according to the third information.

[0270] S2062. The third communication device sends a second SRS to the fourth communication device according to the third information.

[0271] Correspondingly, the fourth communication device receives the second SRS sent by the third communication device according to the third information.

[0272] It should be noted that the above S2061-S2062 need to be executed simultaneously.

[0273] The sending time of the first SRS and the second SRS are consistent.

[0274] The number of the first SRS or the second SRS is one or more, the number of the first SRS and the second SRS is the same, the first SRS and the second SRS are in one-to-one correspondence, and the corresponding first SRS and the second SRS are sent at the same time.

[0275] When the number of the first SRS is one and the number of the second SRS is one, the sending time of the first SRS is the same as the sending time of the second SRS.

[0276] When the number of the second SRS is plural, the multiple first SRSs correspond to the multiple second SRSs one by one, and the sending time of a corresponding first SRS and a corresponding second SRS is the same.

[0277] When the number of the first SRS is one and the number of the second SRS is one, the third communication device may determine a transmission time from one or more transmission times indicated by the third time-frequency resource according to the third information. Thus, the third communication device may simultaneously send the first SRS to the second communication device and the second SRS to the fourth communication device at the transmission time.

[0278] Correspondingly, the second communication device and the fourth communication device can obtain the sending time of the first SRS and the second SRS according to the third information, so that the second communication device and the fourth communication device can be prepared to receive the SRS. Thus, the second communication device can determine the receiving time period of the SRS according to the sending time of the first SRS. The fourth communication device can determine the receiving time period of the SRS according to the sending time of the second SRS.

[0279] The receiving time period of the SRS corresponding to the second communication device may be the same as or different from the receiving time period of the SRS corresponding to the fourth communication device. In some examples, the receiving time period of the SRS may be a certain time period starting from the same sending time of the first SRS and the second SRS. Alternatively, the receiving time period of the SRS may be a certain time period after the same sending time of the first SRS and the second SRS.

[0280] In addition, the SRS reception time period may also be replaced by the SRS reception start time and total reception duration, or the SRS reception end time and total reception duration, or the SRS reception start time, reception end time and total reception duration.

[0281] In this way, the second communication device can receive the first SRS from the third communication device within the SRS reception time period. The fourth communication device can receive the second SRS from the third communication device within the SRS reception time period.

[0282] When the number of the first SRS is multiple and the number of the second SRS is multiple, the second communication device can determine multiple transmission times from one or more transmission times indicated by the third time-frequency resource according to the third information. Thus, for each of the multiple transmission times, the third communication device can simultaneously send a corresponding first SRS to the second communication device and a corresponding second SRS to the fourth communication device at each transmission time. Correspondingly, the second communication device and the fourth communication device can obtain multiple transmission times according to the third information, so that the second communication device and the fourth communication device can be prepared to receive the SRS. Thus, the second communication device and the fourth communication device can determine the reception time period of the SRS according to the multiple transmission times.

[0283] The receiving time period of the SRS corresponding to the second communication device may be the same as or different from the receiving time period of the SRS corresponding to the fourth communication device. In some examples, the receiving time period of the SRS may be a certain time period starting from the earliest time of the multiple transmission times. Alternatively, the receiving time period of the SRS may be a certain time period after the earliest time of the multiple transmission times.

[0284] In addition, the SRS reception time period may also be replaced by the SRS reception start time and total reception duration, or the SRS reception end time and total reception duration, or the SRS reception start time, reception end time and total reception duration.

[0285] In this way, the second communication device can receive multiple first SRSs from the third communication device within the SRS reception period. The fourth communication device can receive multiple second SRSs from the third communication device within the SRS reception period.

[0286] S2071. The second communication device sends fourth information to the first communication device.

[0287] Correspondingly, the first communication device receives the fourth information sent by the second communication device.

[0288] S2072. The fourth communication device sends fifth information to the first communication device.

[0289] Correspondingly, the first communication device receives the fifth information sent by the fourth communication device.

[0290] It should be noted that there is no chronological order between the above S2071 - S2072, and S2071 - S2072 can be executed simultaneously or sequentially.

[0291] The fourth information and the fifth information are used to determine the location information of the third communication device, the fourth information is determined by the second communication device according to the first SRS, and the fifth information is determined by the fourth communication device according to the second SRS.

[0292] Since the transmission time of the SRS is affected by the distance, the second communication device and the fourth communication device are usually arranged at different locations. Therefore, the distance between the second communication device and the third communication device is different from the distance between the fourth communication device and the third communication device.

[0293] Based on the above description, the reception time of the first SRS is different from the reception time of the second SRS. The reception time of the first SRS here refers to the time when the second communication device receives the first SRS, and the reception time of the second SRS refers to the time when the fourth communication device receives the second SRS. Therefore, the second communication device can determine that the fourth information is used to indicate the reception time of the first SRS, and the fourth communication device can determine that the fifth information is used to indicate the reception time of the second SRS.

[0294] When the number of first SRSs is one and the number of second SRSs is one, the second communication device may determine that the fourth information is used to indicate the reception time of the first SRS, and the fourth communication device may determine that the fifth information is used to indicate the reception time of the second SRS.

[0295] It can be seen that the above implementation manner can save the computing resources of the third communication device in determining the location information of the third communication device according to the fourth information and the fifth information.

[0296] When there are multiple first SRSs and multiple second SRSs, the second communication device may determine that the fourth information is used to indicate the reception time of the multiple first SRSs, and the fourth communication device may determine that the fifth information is used to indicate the reception time of the multiple second SRSs.

[0297] The reception times of the multiple first SRSs indicated by the fourth information correspond one-to-one to the reception times of the multiple second SRSs indicated by the fifth information.

[0298] It can be seen that the above implementation manner can improve the accuracy of the third communication device determining the location information of the third communication device according to the third information.

[0299] Thus, the second communication device can send the fourth information to the first communication device, and the fourth communication device can send the fifth information to the first communication device. The first communication device can then determine the location information of the third communication device according to the fourth information and the fifth information.

[0300] The satellite-based positioning method provided by the present application sends a first request to the second communication device through a first communication device, and the first request is used to request the location information of the third communication device, so that the second communication device learns that the first communication device requests to determine the location information of the third communication device by transmitting SRS. The second communication device determines the first information in response to the first request, and the second communication device sends the first information to the first communication device, so that the first communication device can learn from the first information that it is necessary to consider that the second communication device and the fourth communication device are simultaneously covered by the satellite link in which or which time periods. The first communication device can determine the second information, and the first communication device can send the second information to the fourth communication device, and the second information is used to indicate the second time-frequency resource of the available SRS of the second communication device, so that the fourth communication device can learn that it is necessary to determine the time-frequency resource of the SRS used by the second communication device and the fourth communication device to locate the third communication device. The fourth communication device determines the third information according to the second information and the fourth time period, and the fourth communication device sends the third information to the first communication device, the third information is used to indicate the third time-frequency resource of the SRS that can be used by the second communication device and the fourth communication device, and the fourth time period is the time period in which the fourth communication device is covered by the satellite link, so that the first communication device can know which or which SRS time-frequency resources can be used by the second communication device and the fourth communication device. The first communication device sends the third information to the second communication device, the third communication device and the fourth communication device respectively, so that the second communication device, the third communication device and the fourth communication device can know which or which SRS time-frequency resources can be used to locate the third communication device. Thereby, it is helpful to quickly and accurately determine the location information of the third communication device, avoid the phenomenon that the third communication device cannot be located in time due to the lack of satellite link coverage of the second communication device, and also avoid the phenomenon that the third communication device cannot be accurately located due to the lack of timely information fed back to the first communication device when the third communication device may move during the positioning process.

[0301] In this way, the third communication device sends the first SRS to the second communication device according to the third information, and the third communication device sends the second SRS to the fourth communication device according to the third information, and the sending time of the first SRS and the second SRS is the same. The second communication device receives the first SRS according to the third information. The second communication device determines the fourth information according to the reception time of the first SRS, and the second communication device can send the fourth information to the first communication device. The fourth communication device receives the second SRS according to the third information. The fourth communication device determines the fifth information according to the reception time of the second SRS, and the fourth communication device can send the fifth information to the first communication device. The first communication device can determine the location information of the third communication device according to the fourth information and the fifth information. Thereby, the positioning of the third communication device is achieved.

[0302] Based on the description of the above embodiment, the time period indicated by the third time-frequency resource is the third time period. When the number of SRS transmission moments is one, the third time period refers to a period of time including the one SRS transmission moment. When the number of SRS transmission moments is multiple, the third time period refers to a period of time including the multiple SRS transmission moments.

[0303] The third time period is an overlapping time period of the second time period and the fifth time period, the second time period is a time period in which the second communication device can use the SRS, and the fifth time period is a time period in which the fourth communication device can use the SRS.

[0304] The second time period may be represented in a variety of ways.

[0305] As a feasible representation, the second time period includes a sixth time period and a seventh time period, the sixth time period is a time period before the first time period, the seventh time period is a partial time period in the first time period, and the sixth time period is connected to the seventh time period.

[0306] Next, combine Fig. 9 , the second time period is explained by way of example.

[0307] Fig. 9 In the example, the first time period is recorded as the time period from T1 to T2, the sixth time period is recorded as the time period from T3 to T1, and the seventh time period is recorded as the time period from T1 to T4.

[0308] like Fig. 9As shown, due to the time delay of SRS transmission, after the SRS in the T4 to T2 time period is transmitted, the reception time of the SRS may fall outside the T1 to T2 time period, and the second communication device has no satellite link coverage outside the T1 to T2 time period. Therefore, the time-frequency resources of the SRS in the T4 to T2 time period cannot be used to locate the third communication device. Based on this, the first communication device and / or the second communication device can exclude the T4 to T2 time period from the T1 to T2 time period and retain the T1 to T4 time period.

[0309] Moreover, since there is a time delay in the transmission of SRS, after the SRS in the time period from T3 to T1 is transmitted, the reception time of the SRS may fall within the time period from T1 to T2, and the second communication device is covered by the satellite link within the time period from T1 to T2. Therefore, the time and frequency resources of the SRS in the time period from T3 to T1 can be used to locate the third communication device.

[0310] In summary, the first communication device and / or the second communication device may determine that the second time period is the time period from T3 to T4.

[0311] As another feasible representation, the second time period is all or part of the first time period except the time period from T4 to T2. In some examples, the second time period is the seventh time period mentioned above. Alternatively, the second time period is part of the seventh time period mentioned above.

[0312] For example, combining Fig. 9 , the seventh time period is recorded as the time period from T1 to T4. Based on the description of a feasible representation method mentioned above, the first communication device and / or the second communication device may determine that the second time period is the time period from T1 to T4.

[0313] The fifth time period may be represented in a variety of ways.

[0314] As a feasible representation method, the fifth time period includes an eighth time period and a ninth time period, the eighth time period is the time period before the fourth time period, the ninth time period is a partial time period in the fourth time period, and the eighth time period is connected to the ninth time period.

[0315] Next, combine Fig. 9 , the fifth time period is explained by way of example.

[0316] Fig. 9 In the example, the fourth time period is recorded as the time period from T5 to T6, the eighth time period is recorded as the time period from T7 to T5, and the ninth time period is recorded as the time period from T5 to T8.

[0317] like Fig. 9As shown, due to the delay in the transmission of the SRS, after the SRS in the T8 to T6 time period is transmitted, the reception time of the SRS may fall outside the T5 to T6 time period, and the fourth communication device has no satellite link coverage outside the T5 to T6 time period. Therefore, the time-frequency resources of the SRS in the T8 to T6 time period cannot be used to locate the third communication device. Based on this, the fourth communication device can exclude the T8 to T6 time period from the T5 to T6 time period and retain the T5 to T8 time period.

[0318] Furthermore, since there is a time delay in the transmission of the SRS, after the SRS in the time period from T7 to T5 is transmitted, the reception time of the SRS may fall within the time period from T5 to T6, and the fourth communication device is covered by the satellite link. Therefore, the time-frequency resources of the SRS in the time period from T7 to T5 can be used to locate the third communication device.

[0319] In summary, the fourth communication device may determine that the fifth time period is the time period from T7 to T8.

[0320] As another feasible representation, the fifth time period is all or part of the fourth time period except the time period from T8 to T6. In some examples, the fifth time period is the ninth time period mentioned above. Alternatively, the fifth time period is part of the ninth time period mentioned above.

[0321] For example, combining Fig. 9 , the ninth time period is recorded as the time period from T5 to T8. Based on the description of a feasible representation method mentioned above, the fourth communication device may determine that the fifth time period is the time period from T5 to T8.

[0322] Based on the above description, the third time period may include multiple implementations:

[0323] When the second time period is T3 to T4 and the fifth time period is T7 to T8, the fourth communication device can determine that the third time period is T3 to T4 and the overlapping part of T7 to T8 is T7 to T4, that is, the third time period is T7 to T4.

[0324] Therefore, the fourth communication device can select the time-frequency resources of the SRS from the time period from T7 to T4.

[0325] When the second time period is T3 to T4 and the fifth time period is T5 to T8, the fourth communication device may determine that the overlapping portion of T3 to T4 and T5 to T8 is T5 to T4, that is, the third time period is T5 to T4.

[0326] Therefore, the fourth communication device can select the time-frequency resources of the SRS from the time period from T5 to T4.

[0327] When the second time period is T1 to T4 and the fifth time period is T7 to T8, the fourth communication device can determine that the third time period is T1 to T4 and the overlapping part of T7 to T8 is T1 to T4, that is, the third time period is T1 to T4.

[0328] Therefore, the fourth communication device can select the time-frequency resources of the SRS from the time period from T1 to T4.

[0329] When the second time period is T1 to T4 and the fifth time period is T5 to T8, the fourth communication device can determine that the third time period is T1 to T4 and the overlapping part of T7 to T8 is T5 to T4, that is, the third time period is T5 to T4.

[0330] Therefore, the fourth communication device can select the time-frequency resources of the SRS from the time period from T5 to T4.

[0331] In summary, accurate determination of the third time period can improve the utilization of SRS time-frequency resources and can also improve positioning accuracy.

[0332] Based on the description of the above embodiments, the first communication device and / or the second communication device may adopt multiple implementation methods to determine the second time period according to the first information.

[0333] In some examples, the first information may carry a first time threshold value and a second time threshold value, the first time threshold value is used to indicate that the first time-frequency resource of the SRS is available in the sixth time period, and the second time threshold value is used to indicate that the first time-frequency resource of the SRS is unavailable in the tenth time period, the sixth time period is the time period before the first time period, the tenth time period is the other time period in the first time period except the seventh time period, the seventh time period is a partial time period in the first time period, and the seventh time period is connected to the tenth time period.

[0334] The first time threshold value and the second time threshold value may be the same or different in size. The size of the first time threshold value and the second time threshold value is related to the delay of SRS transmission.

[0335] The length of the sixth time period may be equal to the first time threshold, and the length of the tenth time period may be equal to the second time threshold.

[0336] Combination Fig. 9 The first time period is recorded as the time period from T1 to T2, the sixth time period is recorded as the time period from T3 to T1, the seventh time period is recorded as the time period from T1 to T4, and the tenth time period is recorded as the time period from T4 to T2.

[0337] Therefore, the first communication device and / or the second communication device may determine that the second time period is the time period from T3 to T4 according to the first information.

[0338] In addition, the first information may not carry the first time threshold value and the second time threshold value.

[0339] In some examples, the first communication device and / or the second communication device may store the first time threshold and the second time threshold in advance. In this way, the first communication device and / or the second communication device may determine that the second time period is the time period from T3 to T4 according to the first information, the first time threshold and the second time threshold.

[0340] In other examples, the first communication device and / or the second communication device may store the second time threshold in advance, so that the first communication device and / or the second communication device may determine that the second time period is the time period from T1 to T4 according to the first information and the second time threshold.

[0341] Based on the above description, the fourth communication device may store the fifth time period in advance, may store the third time threshold value and the fourth time threshold value in advance, or may store the fourth time threshold value in advance.

[0342] The third time threshold value and the fourth time threshold value may be the same or different in magnitude. The magnitude of the third time threshold value and the fourth time threshold value is related to the delay of SRS transmission.

[0343] The length of the time period from T7 to T5 may be equal to the third time threshold, and the length of the time period from T8 to T6 may be equal to the fourth time threshold.

[0344] In some examples, the fourth communication device may determine that the fifth time period is the time period from T7 to T8 based on the third time threshold and the fourth time threshold.
