[0020] Referring to Figure 1, Figure 1 is a schematic diagram of a wireless communication system according to an embodiment of the present disclosure. As shown in Figure 1, the wireless communication system is a communication system based on cellular mobile communication technology, and the wireless communication system may include a plurality of terminals 11 and a plurality of access devices 12.

[0021] Terminal 11 can refer to a device that provides voice and / or data connectivity to a user. Terminal 11 can communicate with one or more core networks via a Radio Access Network (RAN). Terminal 11 may also be an Internet of Things terminal, such as a sensor device, a mobile phone (or "cellular" phone), or a computer with the Internet of Things.

[0022] The access device 12 may be a network node device in a wireless communication system.

The central unit is configured with a protocol stack for the Packet Data Convergence Protocol (PDCP) layer, the Radio Link Control (RLC) layer, and the Media Access Control (MAC) layer, while the distributed units are configured with a physical (PHY) layer protocol stack. The specific implementation of the access device 12 is not limited in the embodiments of this disclosure.

[0024] A wireless connection can be established between the access device 12 and the terminal 11 via a wireless air interface. In different embodiments, the wireless air interface is a wireless air interface based on the fourth-generation mobile communication network technology (4G) standard.

[0025] Selectively, the wireless communication system may further include a network management device 13. Multiple access devices 12 are each connected to the network management device 13. The network management device 13 may be a core network device in the wireless communication system, for example, a Mobility Management Entity (MME) in an Evolved Packet Core (EPC) network. Alternatively, the network management device may be another core network device such as a Serving Gateway (SGW), Public Data Network Gateway (PGW), Policy and Charging Rules Function (PCRF), or Home Subscriber Server (HSS). The embodiments of the present disclosure are not limited to the implementation of the network management device 13.

[0026] Exemplary, terminal 11 may be a UE in an embodiment of the present disclosure, which may include, but is not limited to, a mobile phone, a wearable device, a vehicle terminal, a roadside unit (RSU), a smart home terminal, an industrial sensing device, and / or a medical device. Access device 12 may be a positioning node in an embodiment of the present disclosure, such as a base station. Network management device 13 may be a core network device in an embodiment of the present disclosure.

[0027] As shown in Figure 2, the information processing method according to the embodiment of this disclosure is performed by a UE and includes the following step S110. In S110, first time interval information for uplink transmission and downlink reception between the UE and the positioning node is transmitted to the core network device, and the first time interval information is used to determine the UE's location information.

[0028] In embodiments of this disclosure, the positioning node may be a base station and / or a satellite, etc. Uplink transmission may include uplink transmission of an uplink time unit to the positioning node. Downlink reception may include receiving a downlink time unit from the positioning node. The time unit may be a subframe, a slot, or other time unit, etc. The first time interval information may indicate a timing difference between the uplink time unit and the downlink time unit, and for example, the first time interval information may include the number of subframes, the number of slots, or the length of the interval, etc.

[0029] In one embodiment, if the positioning node is a satellite, the downlink time unit of downlink reception may be a downlink subframe transmitted by the base station and forwarded by the positioning node. The uplink time unit of uplink transmission may be transmitted by the positioning node to the base station.

[0030] In one embodiment, the UE may transmit first time interval information to a core network device. For example, the core network device may be a Location Management Function (LMF). The core network device can be used to determine the UE's location information based on the first time interval information.

[0031] In one embodiment, the first time interval information for uplink transmission and downlink reception between the UE and the positioning node may be the first time interval information between a downlink time unit transmitted by the downlink-receiving positioning node and an uplink time unit transmitted uplink to the positioning node. The downlink time unit may be a time unit for carrying a first target signal. The uplink time unit may be the time unit closest to the downlink time unit and / or a time unit for carrying a second target signal.

[0032] In one embodiment, the second target signal may be a signal corresponding to the first target signal. For example, the first target signal may be a downlink position reference signal (PRS) or a downlink channel state information-reference signal (CSI-RS). The second target signal may be an uplink channel sounding reference signal (SRS). The first target signal may be included in a downlink time unit. The second target signal may be included in an uplink time unit. The first and second target signals may appear as a pair.

[0033] In one embodiment, the first time interval information includes a first time difference. Prior to step S110, the method may further include the step of determining the first time difference based on a first time in a first downlink time unit received from a positioning node and a second time in a first uplink time unit transmitted by the UE. The first downlink time unit is used to transmit a first target signal, and the first uplink time unit is the uplink time unit closest to the first downlink time unit. For example, the first uplink time unit is the time unit closest to the first downlink time unit in the time domain. Closest can mean closest in the time domain, for example, the time corresponding to the time unit is closest.

[0034] In one embodiment, the first time difference can indicate the time difference between a first time and a first uplink time unit. For example, the second time may be the start or end time of the first uplink time unit or the transmission time of a second target signal. The first time difference may be the time difference between the first time and the end or start time of the first uplink time unit or the transmission time of a second target signal.

[0035] In one embodiment, the first time may be the time when the UE receives the first target signal in the first downlink time unit. The first time can be determined based on the first downlink time unit or the first path in which the first target signal is detected in multipath detection.

[0036] In one embodiment, the first target signal may be PRS or CSI-RS. The first downlink time unit may be a downlink time unit used by the positioning node to transmit the first target signal. The first time may be the time when the UE receives the first target signal in the first downlink time unit. For example, the first time can be determined based on the symbol position where the first target signal was received.

[0037] In one embodiment, the first uplink time unit may be the uplink time unit whose transmission time is closest to the first downlink time unit. For example, the first uplink time unit may be an uplink time unit whose transmission time is before the first downlink time unit and whose transmission time is closest to the first downlink time unit, or it may be an uplink time unit whose transmission time is after the first downlink time unit and whose transmission time is closest to the first downlink time unit.

[0038] The transmission time may be the second time in the first uplink time unit. The second time may be the start time corresponding to the transmission of the first uplink time unit. For example, as shown in Figure 3, the first downlink time unit is subframe i, the first uplink time unit is subframe j whose transmission time is closest to the first time in subframe i, and the first time difference is the time difference T between the time the downlink (DownLink, DL) PRS is received and the end time of the first uplink time unit. RX-TX That is the case.

[0039] In one embodiment, the method may further include the steps of receiving instruction information for a first downlink time unit transmitted by a positioning node, and / or transmitting instruction information for a first uplink time unit to the positioning node. The UE may also further transmit instruction information for a first uplink time unit to a core network device. For example, if the positioning node and the UE transmit separately, the UE transmits instruction information for a first uplink time unit to the core network device, and the positioning node transmits instruction information for a first downlink time unit to the core network device.

[0040] In one embodiment, after receiving instruction information for a second downlink time unit transmitted by a positioning node, the method may further include the step of transmitting instruction information for a first downlink time unit and instruction information for a first uplink time unit to a core network device. The instruction information may include an identifier for the time unit. For example, if the time unit is a subframe, the instruction information may be a subframe number, etc., so that the core network device can accurately identify the first downlink time unit and / or the first uplink time unit.

[0041] The process may include a step of transmitting a processing result determined based on the instruction information for the first downlink time unit and the instruction information for the first uplink time unit to a core network device. Here, the processing result may be used by the core network device to determine the location information of the UE, or the core network device may determine the processing result based on the instruction information for the first downlink time unit and the instruction information for the first uplink time unit.

[0042] In one embodiment, after transmitting the instruction information of the first uplink time unit to the positioning node, the positioning node transmits the instruction information of the first uplink time unit along with the instruction information of the first downlink time unit to the core network device.

[0043] In one embodiment, the method further includes the step of determining a second time difference, the second time difference may be used to indicate a time difference between a second downlink time unit that receives a downlink pilot and a second uplink time unit that transmits an uplink pilot. Accordingly, step S110 may include the step of transmitting a first time difference and a second time difference.

[0044] In one embodiment, the second downlink time unit may be a different time unit from the first downlink time unit, for example, the first downlink time unit and the second downlink time unit may be used to transmit different signals. For example, the first downlink time unit may be used by the positioning node to transmit a first PRS, and the second downlink time unit may be used by the positioning node to transmit a second PRS, etc. Alternatively, the second downlink time unit may be the same time unit as the first downlink time unit. For example, the downlink pilot may be a downlink PRS or downlink CSI-RS, and the second uplink time unit may be an uplink time unit for transmitting the uplink pilot. For example, the second uplink time unit may be used to transmit an uplink pilot corresponding to the downlink pilot. For example, the uplink pilot may be an uplink SRS, etc.

[0045] In one embodiment, the second uplink time unit is the time unit for transmitting the uplink pilot that is closest to the second downlink time unit. Closest to the second downlink time unit can mean being closest to the transmission time of the second downlink time unit, or having the shortest time interval between it and the second downlink time unit, for example, having the fewest number of slots or subframes between it and the second downlink time unit.

[0046] In one embodiment, the second uplink time unit may be a time unit for transmitting an uplink pilot that is located before the second downlink time unit and is closest to the second uplink time unit. Alternatively, the second uplink time unit may be a time unit for transmitting an uplink pilot that is located after the second downlink time unit and is closest to the second uplink time unit.

[0047] Exemplary, as shown in Figure 4, the second downlink time unit receiving the downlink pilot DL PRS is subframe i, the second uplink time unit transmitting the uplink pilot uplink (UpLink, UL) SRS closest to subframe i is subframe j+4, and the second time difference may be the number of subframes and / or slots between the second downlink time unit and the second uplink time unit.

[0048] In one embodiment, the second time difference may be the number of subframes and / or slots between the second uplink time unit and the second downlink time unit. For example, as shown in Figure 4, if the second uplink time unit is located after the second downlink time unit, the second time difference may be the number of subframes and / or slots that are located after the second downlink time unit but before the second uplink time unit, i.e., three subframes. If the second uplink time unit is located before the second downlink time unit, the second time difference may be the number of subframes and / or slots that are located before the second downlink time unit but after the second uplink time unit, provided that the number of subframes and slots are integers.

[0049] The number of slots can be determined based on the number of subframes. Each subframe can contain a predetermined number of slots. For example, each subframe can contain two, four, or eight slots. In this way, the second time difference is used as auxiliary information to correct errors present in the first time difference. To determine the second time difference, it is only necessary to identify the subframes in which the first and second target signals are located, and it is not necessary to determine the specific time when the first target signal is received and the specific time when the second target signal is transmitted. This reduces the computational load and improves efficiency.

[0050] In one embodiment, determining the second time difference may involve determining a target set based on a predetermined rule or configuration information instructed by a core network device, and determining the target value in the target set as the second time difference. For example, in response to the predetermined rule or configuration information containing instruction information, the target value is determined from the target set based on the subcarrier interval information based on the instruction information and transmitted to the core network device as the second time difference. The instruction information is used to instruct the UE to determine the target value by referring to the subcarrier interval information. Here, the instruction information included in the predetermined rule or configuration information may be information such as a command or instruction. For example, if the UE determines that the predetermined rule or configuration information includes a predetermined instruction, it determines the target value from the target set based on the subcarrier interval information.

[0051] In one embodiment, the step of determining a target value from a target set based on subcarrier interval information may include the step of determining a target value from a target set based on subcarrier interval information and a predetermined ratio. For example, the predetermined ratio may be 2, and the target value may be 2 times the subcarrier interval value, and so on.

[0052] In one embodiment, the second downlink time unit may be the same as or different from the first downlink time unit, and the second uplink time unit may be the same as or different from the first uplink time unit.

[0053] In one embodiment, the method may further include the steps of receiving instruction information for a second downlink time unit transmitted by a positioning node, and / or transmitting instruction information for a second uplink time unit to the positioning node. The method may further include the step of transmitting instruction information for a second uplink time unit to a core network device. For example, if the positioning node and the UE transmit separately, the UE transmits instruction information for a second uplink time unit to the core network device, and the positioning node transmits instruction information for a second downlink time unit to the core network device.

[0054] In one embodiment, after receiving instruction information for a second downlink time unit transmitted by a positioning node, the method may further include the step of transmitting instruction information for a second downlink time unit and instruction information for a second uplink time unit to a core network device.

[0055] This may include a step of transmitting a processing result determined based on the instruction information for the second downlink time unit and the instruction information for the second uplink time unit to a core network device. Here, the processing result may be used by the core network device to determine the location information of the UE. Alternatively, the core network device may determine the processing result based on the instruction information for the first downlink time unit and the instruction information for the first uplink time unit.

[0056] In one embodiment, the step of transmitting the second uplink time unit instruction information may include the step of transmitting the second uplink time unit instruction information to a positioning node. The second downlink time unit instruction information may be received from the positioning node, for example, by transmitting the second uplink time unit instruction information to the positioning node, which can then transmit it to a network device.

[0057] In one embodiment, after receiving instruction information for a second downlink time unit transmitted by a positioning node, the system transmits it to the core network device along with instruction information for a second uplink time unit. Alternatively, the system may include the step of transmitting instruction information for a second uplink time unit to a positioning node, which then transmits the instruction information for a second uplink time unit to the core network device along with instruction information for a second downlink time unit.

[0058] In one embodiment, the first time interval information is used by the core network device to determine the location information of the UE in a manner such as multi-round-trip time (multi-RTT).

[0059] Thus, the first time difference can reflect the time interval between the downlink time unit on the UE side and the adjacent uplink time unit, and the second time difference, such as the number of subframes or slots, can reflect the uplink and downlink time interval scale based on the target signal between the UE and the positioning node. Therefore, the second time difference can correct the error of the first time difference and more comprehensively reflect the uplink and downlink time interval situation between the UE and the positioning node, making it even easier for the network side to determine the UE's location information based on the first time interval information.

[0060] In one embodiment, the first time interval information includes a third time difference. Accordingly, the method further includes the step of determining the third time difference based on a first time in a first downlink time unit received from a positioning node and a third time in a third uplink time unit transmitted by the UE.

[0061] A first downlink time unit is used to transmit a first target signal, and a third uplink time unit is an uplink time unit for transmitting a second target signal, which is closest to the first downlink time unit. Here, the third uplink time unit may be an uplink time unit for transmitting a second target signal, whose transmission time is closest to the first downlink time unit. The transmission time may be a third time. The third time may be the time when the UE transmits the second target signal in the third uplink time unit. For example, the third time may be determined based on the symbol position in the third uplink time unit where the second target signal is transmitted.

[0062] In one embodiment, the third uplink time unit may be an uplink time unit for transmitting a second target signal whose transmission time is before the first downlink time unit and is closest to the first downlink time unit. Alternatively, it may be an uplink time unit for transmitting a second target signal whose transmission time is after the first downlink time unit and is closest to the first downlink time unit.

[0063] In one embodiment, the third uplink time unit may be the same as or different from the first uplink time unit.

[0064] In one embodiment, the first time may be the time when the UE receives the first target signal in the first downlink time unit. The third time may be the time when the UE transmits the second target signal in the third uplink time unit. The third time difference may be the time interval between the first time and the third time. For example, as shown in Figure 5, the first downlink time unit is subframe i, the first time is the time when the downlink (DownLink, DL) PRS is received, the third uplink time unit is subframe j+4, and the third time is the time when the uplink (UpLink, UL) SRS is transmitted. Thus, the third time difference can reflect the uplink and downlink time intervals between the UE and the positioning node based on the target signal, and can be used by the network side to determine the UE's location information based on a method such as multi-RTT corresponding to the target signal, thereby reducing errors due to the high-speed movement of the positioning node.

[0065] In one embodiment, the method may further include the steps of receiving instruction information for a first downlink time unit transmitted by a positioning node, and / or transmitting instruction information for a third uplink time unit to the positioning node. The UE may also transmit instruction information for a third uplink time unit to a core network device. For example, if the positioning node and the UE transmit separately, the UE transmits instruction information for a third uplink time unit to the core network device, and the positioning node transmits instruction information for a first downlink time unit to the core network device.

[0066] In one embodiment, after receiving instruction information for a first downlink time unit transmitted by a positioning node, the method may further include the step of transmitting instruction information for a first downlink time unit and instruction information for a third uplink time unit to a core network device.

[0067] This may include a step of transmitting the processing result, determined based on the instruction information for the first downlink time unit and the instruction information for the third uplink time unit, to a core network device. Here, the processing result may be used by the core network device to determine the location information of the UE. Alternatively, the core network device may determine the processing result based on the instruction information for the first downlink time unit and the instruction information for the first uplink time unit.

[0068] In one embodiment, the instruction information for the third uplink time unit is transmitted to the positioning node, and the positioning node transmits the instruction information for the third uplink time unit along with the instruction information for the first downlink time unit to the core network device.

[0069] In one embodiment, the time unit instruction information may include a subframe identifier, such as a subframe number, which can be used by a core network device to accurately identify a first downlink time unit and / or a third uplink time unit.

[0070] In this way, by providing first time interval information for the uplink and downlink between the UE and the positioning node, the network can more accurately determine the UE's location. For example, in a satellite communication scenario, the first time interval information can also reflect the delay in the uplink and downlink between the UE and the positioning node (satellite), thereby improving the network's positioning accuracy of the UE.

[0071] Furthermore, the technical features described in the above-mentioned embodiments can be arbitrarily rearranged, combined, and reordered, provided they do not contradict each other, and can be arbitrarily combined to form new technical proposals for methods.

[0072] Those skilled in the art will understand that the methods relating to the embodiments of this disclosure may be performed alone, or in conjunction with some methods of the embodiments of this disclosure or other embodiments, or with some methods of the related technology.

[0073] In some embodiments, as shown in Figure 5, the first time interval information includes a first time difference. The method further includes the following step S101. In S101, a first time difference is determined based on a first time in a first downlink time unit received from the positioning node and a second time in a first uplink time unit transmitted to the positioning node. The first downlink time unit is used to transmit the first target signal, and the first uplink time unit is the uplink time unit closest to the first downlink time unit. S110 may include the following step S111. In S111, the first time delay is transmitted.

[0074] In one embodiment, the first time may be the time when the first target signal is received. The first time can be determined based on the first downlink time unit or the first path in which the first target signal is detected in multipath detection.

[0075] In one embodiment, the first target signal may be PRS or CSI-RS. The first downlink time unit may be a downlink time unit used by the positioning node to transmit the first target signal. The first time may be the time when the UE receives the first target signal in the first downlink time unit. For example, the first time can be determined based on the symbol position where the first target signal was received.

[0076] In one embodiment, the first uplink time unit may be the uplink time unit whose transmission time is closest to the first downlink time unit. For example, the first uplink time unit may be an uplink time unit whose transmission time is earlier than the first downlink time unit and whose transmission time is closest to the first downlink time unit, or it may be an uplink time unit whose transmission time is later than the first downlink time unit and whose transmission time is closest to the first downlink time unit.

[0077] The transmission time may be a second time in the first uplink time unit. The second time may be the start time corresponding to the transmission of the first uplink time unit. For example, the first time difference may be the time difference between the time the downlink PRS is received and the start time of the first uplink time unit.

[0078] For content that overlaps with other embodiments or corresponds to other embodiments, please refer to the relevant content of the aforementioned embodiments, such as step S110, and no further detailed explanation will be provided here.

[0079] In some embodiments, as shown in Figure 6, the method further includes the following step S102. In S102, a second time difference is determined to indicate the time difference between a second downlink time unit that receives a downlink pilot from a positioning node and a second uplink time unit that transmits an uplink pilot to a positioning node. S110 may include the following step S112. In S112, the first time difference and the second time difference are transmitted.

[0080] In one embodiment, the second time difference is indicated by the number of subframes and / or slots.

[0081] In one embodiment, the downlink pilot includes a downlink PRS or a downlink CSI-RS, and / or the uplink pilot includes an uplink SRS.

[0082] In one embodiment, as shown in Figure 7, step S102 may include the following steps S1021 and S1022. In S1021, the target set is determined based on predetermined rules or configuration information instructed by the core network device. In S1022, the target value in the target set is determined as the second time difference.

[0083] In one embodiment, prior to step S1022, the method may further include the steps of determining whether the configuration information instructed by a predetermined rule or core network device includes instruction information, and determining a target value from a target set based on subcarrier interval information in response to the configuration information instructed by the predetermined rule or core network device including instruction information.

[0084] Thus, efficiency can be further improved by determining the second time difference based on subcarrier spacing information, without needing to determine the subframe position and the number of subframes corresponding to the second time difference. Furthermore, since the subcarrier spacing is related to uplink and downlink transmission between the UE and the positioning node, the second time difference determined based on the subcarrier spacing is better suited to the characteristics of uplink and downlink transmission, and the accuracy of the second time difference in satellite communication scenarios can be improved.

[0085] In one embodiment, the second downlink time unit may be a different time unit from the first downlink time unit. For example, the first downlink time unit and the second downlink time unit are used to transmit different signals. For example, the first downlink time unit is used by the positioning node to transmit a first PRS, and the second downlink time unit is used by the positioning node to transmit a second PRS, and so on. Alternatively, the second downlink time unit may be the same time unit as the first downlink time unit. For example, the downlink pilot may be a downlink PRS or a downlink CSI-RS, and the second uplink time unit may be an uplink time unit for transmitting the uplink pilot. For example, the second uplink time unit may be used to transmit an uplink pilot corresponding to the downlink pilot. For example, the uplink pilot may be an uplink SRS, etc.

[0086] In one embodiment, the second uplink time unit is the time unit for transmitting the uplink pilot that is closest to the second downlink time unit. Being closest to the second downlink time unit can mean being closest to the transmission time of the second downlink time unit, or having the shortest time interval between it and the second downlink time unit, for example, having the fewest number of slots or subframes between it and the second downlink time unit.

[0087] In one embodiment, the second uplink time unit may be a time unit for transmitting an uplink pilot that is located before the second downlink time unit and is closest to the second uplink time unit. Alternatively, the second uplink time unit may be a time unit for transmitting an uplink pilot that is located after the second downlink time unit and is closest to the second uplink time unit.

[0088] In one embodiment, the second time difference may be the number of subframes and / or slots between the second uplink time unit and the second downlink time unit. For example, if the second uplink time unit is located after the second downlink time unit, the second time difference may be the number of subframes and / or slots that are located after the second downlink time unit but before the second uplink time unit. If the second uplink time unit is located before the second downlink time unit, the second time difference may be the number of subframes and / or slots that are located before the second downlink time unit but after the second uplink time unit. However, the number of subframes and the number of slots are integers.

[0089] The number of slots can be determined based on the number of subframes. Each subframe can contain a predetermined number of slots. For example, each subframe can contain two, four, or eight slots. In this way, the second time difference is used as auxiliary information to correct errors present in the first time difference. To determine the second time difference, it is only necessary to identify the subframes in which the first and second target signals are located, and it is not necessary to determine the specific time when the first target signal is received and the specific time when the second target signal is transmitted. This reduces the computational load and improves efficiency.

[0090] For content that overlaps with other embodiments or corresponds to other embodiments, please refer to the relevant content of the aforementioned embodiments, such as step S110, and no further detailed explanation will be provided here.

[0091] In some embodiments, as shown in Figure 8, the first time interval information includes a third time difference. The method further includes step S103 below. In S103, a third time difference is determined based on the first time in the first downlink time unit received from the positioning node and the third time in the third uplink time unit transmitted to the positioning node. The first downlink time unit is used to transmit the first target signal, and the third uplink time unit is used to transmit the second target signal and is the time unit closest to the first downlink time unit. Step S110 may include the following step S113. In S113, a third time delay is transmitted.

[0092] In one embodiment, the first target signal includes PRS or CSI-RS. A first downlink time unit is used to transmit a first target signal, and a third uplink time unit is an uplink time unit for transmitting a second target signal whose transmission time is closest to that of the first downlink time unit. Here, the transmission time of the third uplink time unit may be a third time, which may be the time when the second target signal is transmitted in the third uplink time unit. For example, the third time may be determined based on the symbol position where the second target signal is transmitted in the third uplink time unit.

[0093] In one embodiment, the first time may be the time when the first target signal is received in the first downlink time unit, and the third time may be the time when the second target signal is transmitted in the third uplink time unit. For example, the third time may be determined based on the symbol position corresponding to the transmission of the second target signal included in the third uplink time unit.

[0094] In one embodiment, the third uplink time unit may be an uplink time unit for transmitting a second target signal whose transmission time is earlier than the first downlink time unit and closest to the first downlink time unit, or it may be an uplink time unit for transmitting a second target signal whose transmission time is later than the first downlink time unit and closest to the first downlink time unit.

[0095] In one embodiment, the first time may be the time when the first target signal is received, and the third time may be the time when the second target signal is transmitted. The third time difference may be the time interval between the first time and the third time. For example, as shown in Figure 9, the first downlink time unit is subframe i, the first time is the time when the downlink (DownLink, DL) PRS in subframe i is received, the third uplink time unit is subframe j+4, the third time is the time when the uplink (UpLink, UL) SRS in subframe j+4 is transmitted, and the third time difference T RX-TX This is the time interval between the first time point and the third time point.

[0096] Thus, the third time difference can reflect the time intervals between the UE and the positioning node based on the target signal for uplink and downlink. Therefore, it can be used by the network to determine the UE's location based on methods such as multi-RTT corresponding to the target signal, thereby reducing errors due to the high-speed movement of the positioning node.

[0097] For content that overlaps with other embodiments or corresponds to other embodiments, please refer to the relevant content of the aforementioned embodiments, such as step S110, and no further detailed explanation will be provided here.

[0098] Furthermore, the technical features described in the above-mentioned embodiments can be arbitrarily rearranged, combined, and reordered, provided they do not contradict each other, and can be arbitrarily combined to form new technical proposals for methods.

[0099] Those skilled in the art will understand that the methods relating to the embodiments of this disclosure may be performed alone, or in conjunction with some methods of the embodiments of this disclosure or other embodiments, or with some methods of the related technology.

[0100] As shown in Figure 10, an embodiment of the present disclosure provides an information processing method performed by a positioning node. The method includes the following step S210. In S210, a second time interval information of downlink transmission and uplink reception between the positioning node and the UE is transmitted to the core network device, and this second time interval information is used to determine the UE's location.

[0101] In embodiments of this disclosure, the positioning node may be a base station or a satellite. In one embodiment, the second time interval information includes a fourth time difference. The method may further include the step of determining a fourth time difference based on a fourth time in a first downlink time unit transmitted to the UE and a fifth time in a first uplink time unit received from the UE, wherein the first uplink time unit is used to receive a second target signal, and the first downlink time unit is the downlink time unit closest to the first uplink time unit. The second target signal may be an SRS, and the first downlink unit is the downlink unit closest to the first uplink unit receiving the SRS. Closest can mean closest in the time domain, for example, closest to the time corresponding to the time unit.

[0102] The fourth time difference can indicate the time interval between the first downlink unit and the fifth time. The fifth time may be the time when the positioning node receives the second target signal in the first uplink time unit, which can be determined, for example, based on the symbol position at which the second target signal was received. The first downlink time unit is the uplink time unit closest to the fifth time in the first uplink time unit. The fourth time may be the start time, end time, or the time when the positioning node transmits the first target signal in the first downlink time unit. For example, the first target signal may be PRS or CSI-RS, and the second target signal may be SRS, etc.

[0103] In one embodiment, the second time interval information includes a fourth time difference. Prior to step S210, the method may further include the step of determining the fourth time difference based on a fourth time in a first downlink time unit transmitted to the UE and a fifth time in a first uplink time unit received from the UE. The first uplink time unit is used to receive the second target signal, and the first downlink time unit is the downlink time unit closest to the first uplink time unit.

[0104] In one embodiment, the fourth time may be the time when the positioning node transmits the first target signal in the first downlink time unit.

[0105] In one embodiment, the first target signal may be PRS or CSI-RS. The first downlink time unit may be the downlink time unit used by the positioning node to transmit the first target signal. The fourth time may be the time at which the positioning node transmits the first target signal in the first downlink time unit. For example, the fourth time can be determined based on the symbol position at which the first target signal is transmitted.

[0106] In one embodiment, the first downlink time unit may be the downlink time unit whose transmission time is closest to the first uplink time unit. For example, the first downlink time unit may be the downlink time unit whose transmission time is before the first uplink time unit and whose transmission time is closest to the first uplink time unit, or it may be the downlink time unit whose transmission time is after the first uplink time unit and whose transmission time is closest to the first uplink time unit.

[0107] In one embodiment, the method further includes the step of determining a fifth time difference, the fifth time difference may be used to indicate a time difference between a second downlink time unit that transmits a downlink pilot and a second uplink time unit that receives an uplink pilot. Accordingly, step S110 may include the step of transmitting a fourth time difference and a fifth time difference.

[0108] In one embodiment, the second downlink time unit may be a different time unit from the first downlink time unit. For example, the first downlink time unit and the second downlink time unit are used to transmit different signals. For example, the first downlink time unit is used by the positioning node to transmit a first PRS, and the second downlink time unit is used by the positioning node to transmit a second PRS, etc. Alternatively, the second downlink time unit may be the same time unit as the first downlink time unit. For example, the downlink pilot may be a downlink PRS or a downlink CSI-RS, and the second uplink time unit may be an uplink time unit for receiving the uplink pilot. For example, the second uplink time unit may be used to receive an uplink pilot corresponding to the downlink pilot. For example, the uplink pilot may be an uplink SRS, etc.

[0109] In one embodiment, the second uplink time unit is the time unit for receiving the uplink pilot that is closest to the second downlink time unit. Being closest to the second downlink time unit can mean being closest to the reception time of the second downlink time unit, or having the shortest time interval between it and the second downlink time unit, for example, having the fewest number of slots or subframes between it and the second downlink time unit.

[0110] In one embodiment, the second uplink time unit is a time unit for receiving an uplink pilot that is located before the second downlink time unit and is closest to the second uplink time unit, or the second uplink time unit is a time unit for receiving an uplink pilot that is located after the second downlink time unit and is closest to the second uplink time unit.

[0111] In one embodiment, the fifth time difference may be the number of subframes and / or slots between the second uplink time unit and the second downlink time unit. For example, if the second uplink time unit is located after the second downlink time unit, the fifth time difference may be the number of subframes and / or slots that are located after the second downlink time unit but before the second uplink time unit. If the second uplink time unit is located before the second downlink time unit, the fifth time difference may be the number of subframes and / or slots that are located before the second downlink time unit but after the second uplink time unit. However, the number of subframes and the number of slots are integers.

[0112] The number of slots can be determined based on the number of subframes. Each subframe can contain a predetermined number of slots. For example, each subframe can contain two, four, or eight slots. In this way, the fifth time difference is used as auxiliary information to correct errors present in the fourth time difference. Determining the fifth time difference only requires identifying the subframes in which the first and second target signals are located, and does not require determining the specific time when the first target signal is received and the specific time when the second target signal is transmitted. This reduces computational complexity and improves efficiency.

[0113] In one embodiment, the step of determining the fifth time difference may be the step of determining a target set based on a predetermined rule or configuration information instructed by a core network device, and determining the target value in the target set as the fifth time difference. For example, in response to the predetermined rule or configuration information containing instruction information, the target value is determined from the target set based on the subcarrier interval information based on the instruction information and transmitted to the core network device as the fifth time difference. The instruction information is used to instruct the UE to determine the target value by referring to the subcarrier interval information, and for example, the instruction information may be information such as a command or instruction, and is used to determine whether the UE needs to determine the target value from the target set based on the subcarrier interval information.

[0114] In one embodiment, the step of determining a target value from a target set based on subcarrier interval information may include the step of determining a target value from a target set based on subcarrier interval information and a predetermined ratio. For example, the predetermined ratio may be 2, and the target value may be twice the subcarrier interval value.

[0115] In one embodiment, the second time interval information is used by the core network device to determine the location information of the UE in a manner such as multi-round-trip time (multi-RTT).

[0116] Thus, the fourth time difference can reflect the time interval between the downlink time unit on the positioning node side and the adjacent uplink time unit, and the fifth time difference, such as the number of subframes or slots, can reflect the uplink and downlink time interval scale based on the target signal between the UE and the positioning node. Therefore, the fifth time difference can correct the error of the fourth time difference and can more comprehensively reflect the uplink and downlink time interval situation between the UE and the positioning node, making it even easier for the network side to determine the UE's location information based on the second time interval information.

[0117] In one embodiment, the second time interval information includes a sixth time difference. Accordingly, the method further includes the step of determining the sixth time difference based on a fourth time in a first downlink time unit transmitted to the UE and a sixth time in a third uplink time unit received from the UE.

[0118] A first downlink time unit is used to transmit a first target signal, and the first downlink time unit is the downlink time unit for transmitting the first target signal whose transmission time is closest to that of a third uplink time unit. Here, the fourth time may be the time when the first target signal is transmitted in the first downlink time unit. This can be determined, for example, based on the symbol position where the first target signal is transmitted. The reception time of the third uplink time unit may be a sixth time. The sixth time may be the time when the positioning node receives a second target signal in the third uplink time unit. For example, the sixth time can be determined based on the symbol position where the second target signal is received in the third uplink time unit.

[0119] In one embodiment, the first downlink time unit may be a downlink time unit for transmitting a first target signal whose transmission time is before the third uplink time unit and is closest to the third uplink time unit, or it may be a downlink time unit for transmitting a first target signal whose transmission time is after the third uplink time unit and is closest to the third uplink time unit.

[0120] In one embodiment, the fourth time may be the time when the positioning node transmits a first target signal in a first downlink time unit, and the sixth time may be the time when the positioning node receives a second target signal in a third uplink time unit. The sixth time difference may be the time interval between the fourth time and the sixth time. For example, the fourth time may be the time when the DownLink (DL) PRS is received, and the sixth time may be the time when the UpLink (UL) SRS is transmitted. Thus, the sixth time difference can reflect the uplink and downlink time intervals between the UE and the positioning node based on the target signal, and can be used by the network side to determine the UE's location information based on a method such as multi-RTT corresponding to the target signal, thereby reducing errors due to the high-speed movement of the positioning node.

[0121] In one embodiment, the method may further include the steps of transmitting instruction information for a first downlink time unit to the UE, and / or receiving instruction information for a first uplink time unit transmitted by the UE. The method may further include the step of transmitting instruction information for a first downlink time unit and instruction information for a first uplink time unit to a core network device. The step of transmitting the instruction information for the first downlink time unit may be the step of transmitting the instruction information for the first downlink time unit to the UE. The step of receiving the instruction information for the first uplink time unit may be the step of receiving the instruction information for the first uplink time unit transmitted by the UE.

[0122] In one embodiment, the instruction information may include information such as a subframe identifier, for example, a subframe number, which can be used by a core network device to accurately identify a first downlink time unit and / or a first uplink time unit.

[0123] In one embodiment, the second time interval information further includes a fifth time difference. The method may further include the step of determining a fifth time difference to indicate the time difference between a second downlink time unit that transmits a downlink pilot and a second uplink time unit that receives an uplink pilot.

[0124] In one embodiment, the fifth time difference is indicated by the number of subframes and / or slots.

[0125] In one embodiment, the fifth time difference can indicate the number of subframes and / or slots between a second downlink time unit in which the positioning node transmits a downlink pilot and a second uplink time unit in which it receives an uplink pilot.

[0126] In one embodiment, the downlink pilot includes a downlink PRS or CSI-RS, and / or the uplink pilot includes an uplink SRS.

[0127] In one embodiment, the step of determining the fifth time difference may include determining a target set based on a predetermined rule or configuration information instructed by a core network device, and determining the target value in the target set as the fifth time difference.

[0128] In one embodiment, prior to the step of determining the target value in the target set as a fifth time difference, the method may further include the steps of determining whether the configuration information indicated by a predetermined rule or core network device contains instruction information, and determining the target value from the target set based on subcarrier interval information in response to the configuration information indicated by the predetermined rule or core network device containing instruction information.

[0129] In one embodiment, the method may further include the steps of transmitting instruction information for a second downlink time unit to the UE, and / or receiving instruction information for a second uplink time unit transmitted by the UE. The method may further include the step of transmitting instruction information for a second downlink time unit and instruction information for a second uplink time unit to a core network device. The step of transmitting the instruction information for the second downlink time unit may be the step of transmitting the instruction information for the second downlink time unit to the UE. The step of receiving the instruction information for the second uplink time unit may be the step of receiving the instruction information for the second uplink time unit transmitted by the UE.

[0130] In one embodiment, the second time interval information includes a sixth time difference. The method further includes the step of determining a sixth time difference based on a fourth time in a first downlink time unit transmitted to the UE and a sixth time in a third uplink time unit received from the UE. The first downlink time unit is used to transmit the first target signal, and the third uplink time unit is an uplink time unit for transmitting the second target signal, the one whose transmission time is closest to the first downlink time unit.

[0131] In one embodiment, the fourth time may be the time when the positioning node transmits a first target signal in a first downlink time unit, and the sixth time may be the time when the positioning node receives a second target signal in a third uplink time unit.

[0132] In one embodiment, the method may further include the steps of transmitting instruction information for a first downlink time unit to a UE, and / or receiving instruction information for a third uplink time unit transmitted by the UE. The method may further include the step of transmitting instruction information for a first downlink time unit and instruction information for a third uplink time unit to a core network device. The step of transmitting the instruction information for the first downlink time unit may be the step of transmitting the instruction information for the first downlink time unit to the UE, and the step of receiving the instruction information for the third uplink time unit may be the step of receiving the instruction information for the third uplink time unit transmitted by the UE.
