Description

Technical Field

[0001] This disclosure relates to, but is not limited to, the field of wireless communication technology, and in particular to an information processing method, apparatus, communication device, and storage medium. Background Technology

[0002] Non-terrestrial network (NTN) communication, such as satellite communication, has been adapted to an increasing number of application scenarios due to its wide coverage, strong disaster resistance, and large capacity. When satellites, such as neighbor satellites, communicate with user equipment (UE), it is possible that due to the not particularly dense deployment of the satellite constellation, the neighbor satellites may not receive the signals transmitted by the UE, and / or the UE may not receive the signals transmitted by the neighbor satellites. For example, the UE or the satellite may not be able to receive the downlink positioning reference signal (DL-PRS) or the uplink sounding reference signal (UL-SRS).

[0003] If the UE or satellite cannot receive the desired positioning signal, such as DL-PRS or UL-SRS, network positioning measurements cannot be performed, which in turn prevents the completion of network positioning or the use of these positioning signals to verify whether the UE's location is correct.

Of course, those skilled in the art will understand that the multiple embodiments provided in this disclosure can be executed individually, or in combination with the methods of other embodiments in this disclosure, or individually or in combination with some methods in other related technologies; this disclosure does not limit these aspects.

[0172] It should be noted that when multiple execution entities are involved in the embodiments of this disclosure, when one execution entity sends a certain transmission to another execution entity, it can mean that one execution entity sends the transmission directly to another execution entity, or it can mean that one execution entity sends the transmission to another execution entity through any other device; the embodiments of this disclosure do not limit this.

[0173] To better understand the technical solutions described in any embodiment of this disclosure, some aspects of the related technology will be described first:

[0174] Non-terrestrial network (NTN) communications, such as satellite communications, have been included in 3GPP discussions regarding 5G standards due to their wide coverage, strong disaster resilience, and high capacity. The NTN scenarios defined in TR38.821 include scenarios based on Geostationary Earth Orbiting (GEO) satellites and scenarios based on Non-Geostationary Earth Orbiting (NGSO) satellites. The NTN network structure can be as follows... Figure 2 As shown, this NTN network architecture has two types: transparent forwarding architecture and regenerative architecture. In the transparent architecture, the satellite plays a transparent forwarding role, meaning communication between the base station and the UE is relayed via the satellite; generally, it's assumed that the NTN gateway and base station are very close and can be approximated as being in the same location. In the regenerative architecture, a portion of the base station (DU) or the entire base station structure is on the satellite, which has data processing capabilities.

[0175] Currently, the positioning methods in 5G NR include the following types: Downlink Time Difference of Arrival (DL-TDOA), Uplink Time Difference of Arrival (UL-TDOA), Multi-Round Trip Time (Multi-RTT), Downlink Angle-of-Departure (DL-AOD), or Uplink Angle of Arrival (UL-AOA). Considering the large beam range of satellites, it is difficult for the UE and satellite to accurately measure variables related to angles. Therefore, DL-TDOA, UL-TDOA, and / or Multi-RTT positioning methods are typically considered.

[0176] The DL-TDOA positioning method can be as follows: The UE receives downlink positioning reference signals (DL-PRS) from different Transmitter Receiver Points (TRPs) to measure the downlink reference signal time difference (DL-RSTD). The UE or LMF then uses multiple RSTD measurements and the positions of each TRP to estimate the UE's positioning. The UL-TDOA positioning method can be as follows: Different TRPs receive uplink sounding reference signals (UL-SRS) from the UE to measure the uplink relative time of arrival (UL-RTOA). The LMF then uses multiple UL-RTOA measurements and the positions of each TRP to estimate the UE's positioning. The Multi-RTT positioning method can be as follows: different TRPs transmit DL-PRS signals and receive UL-SRS signals transmitted by the UE. The LMF estimates the UE's positioning based on the UE-Rx-Tx time difference, the TRP-Rx-Tx time differences, and the positions of each TRP. Here, the UE-Rx-Tx time difference is the time interval between the UE measuring the reception of the DL-PRS signal and the transmission of the UL-SRS signal; the TRP-Rx-Tx time difference is the time difference between the satellite transmitting the DL-PRS signal and receiving the UL-SRS signal.

[0177] If the NTN network is a regenerative architecture, the satellite directly transmits positioning-related signals; if the NTN network is a transparent architecture, the gNB transmits positioning-related signals and forwards them to the UE via the satellite; in both architectures, signal transmission is directly between the satellite and the UE.

[0178] In the WI phase of Rel-18, the accuracy of network-verified UE location and network-based positioning were mentioned. Rel-18 discussed the topic of network-verified UE location and reduced the priority of network positioning. However, network positioning may still be discussed in the future. Furthermore, in the methods currently discussed for network-side verification of UE's Global Navigation Satellite System (GNSS) location, there is a continued use of traditional Time-Reversal (TR) positioning methods, such as Multi-RTT. Therefore, discussing NTN network positioning is necessary.

[0179] When a satellite transmits DL-PRS using the transmit power specified in 3GPP TR 38.821, or when a UE transmits UL-SRS using the transmit power specified in 3GPP TR 38.821, there may be situations where the DL-PRS signal received by the UE is weak, or the UL-SRS signal received by the satellite is weak.

[0180] When a user transmits a UL-SRS signal at its current maximum transmit power (23dBm), other satellites performing positioning measurements, such as neighboring satellites, may not be able to receive the signal. The uplink budget analysis of two adjacent satellites in the Starlink Steam-1 constellation (simulation parameters refer to 3GPP 38.821set12GHz0.4MHz) yielded the simulation results shown in Table 1.

[0181]

[0182] Table 1

[0183] When all satellites performing positioning send DL-PRS signals to the user, the user may not be able to receive signals from some neighboring satellites: a downlink budget analysis was performed on two adjacent satellites of the Starlink Steam-1 constellation (simulation parameters refer to 3GPP 38.821set1 2GHz 30MHz), and the simulation results are shown in Table 2.

[0184]

[0185] Table 2

[0186] The simulation above shows that when a neighboring satellite communicates with the UE, the neighboring satellite may not receive the UL-SRS signal transmitted by the UE. Due to the satellite's high transmit power, the UE may be able to receive the DL-PRS signal transmitted by the neighboring satellite, but if the satellite constellation is not densely deployed, the UE may also fail to receive the DL-PRS signal transmitted by the neighboring satellite. If the UE or neighboring satellites cannot receive the desired signal (DL-PRS or UL-SRS), positioning measurements cannot be performed, thus preventing the completion of positioning or the verification of the UE's correct location using these parameters. Figure 3 As shown, a relationship between the location of a UE and a satellite (e.g., a neighboring satellite) is provided; where UE1 can be a UE not on a satellite, and UE2 can be a UE on a satellite. It can be seen that there are situations where UE1 and UE2 cannot communicate with neighboring satellites, regardless of whether the UE is on a satellite or not.

[0187] This disclosure provides an information processing method that can solve the aforementioned problem of the UE's inability to communicate with a satellite. For example... Figure 4 As shown, this disclosure provides an information processing method, executed by an LMF, comprising:

[0188] Step S41: Send a request message to the serving base station, wherein the request message is used to request the beam information of the first beam of the serving base station; wherein the beam information of the first beam is used by the neighboring base station to adjust the beam configuration of the second beam; the second beam after adjusting the beam configuration is used for the transmission of positioning signals between the neighboring base station and the UE.

[0189] Here, the neighboring base station adjusts the beam configuration of the second beam using the beam information of the first beam, and the second beam with the adjusted beam configuration is used for the transmission of positioning signals between the neighboring base station and the UE.

[0190] Here, a neighboring base station can be on a neighboring satellite, or a neighboring satellite is a satellite used to relay signals between a neighboring base station and a UE.

[0191] In one embodiment, the serving base station and the neighboring base station can be, but are not limited to, at least one of the following: a 3G base station, a 4G base station, a 5G base station, and other evolved base stations. In another embodiment, both the serving base station and the neighboring base station can be base stations in satellite communications.

[0192] In another embodiment, the serving base station is a base station to which the UE has registered or a base station that has located the UE; the neighboring base station is a base station within a predetermined range of the UE or a base station that has not yet located the UE, etc.

[0193] For example, the serving base station can be a first base station; the neighboring base station can be a second base station. For example, the serving base station can be a service gNB, and the neighboring base station can be a neighbor gNB.

[0194] In one embodiment, the UE can be various mobile terminals or fixed terminals. For example, the UE can be, but is not limited to, a mobile phone, a computer, a server, a wearable device, a game control platform, a multimedia device, or various sensors.

[0195] In one embodiment, LMF is a logical node, function, or entity that implements a function, which can be flexibly arranged in the core network.

[0196] In one embodiment, sending the request information to the serving base station in step S41 can be: sending a service base station (gNB) request to the serving base station via the NR Positioning Protocol A (NRPPa) protocol.

[0197] In one embodiment, the beam information of the first beam may be, but is not limited to, information related to the geographical location of the first beam and / or information related to the direction of the first beam. The direction of the first beam refers to the direction of any one of the beams in the first beam. The geographical location information of the first beam may be, but is not limited to, the location of the center point of the first beam, the geographical locations of the two boundaries of the first beam, and / or the location of any point in the first beam.

[0198] In one embodiment, the beam information of the first beam includes, but is not limited to, the location information of the beam center point of the first beam and / or the direction of at least one beam of the first beam.

[0199] In one embodiment, the first beam may be the beam of the serving base station. For example, the first beam is the serving beam of the serving base station.

[0200] In one embodiment, the beam configuration of the second beam includes, but is limited to, at least one of the following: the geographical location of at least one beam in the second beam, the number of second beams, the direction of at least one beam in the second beam, and the coverage area of ​​at least one beam in the second beam.

[0201] In one embodiment, the second beam can be the beam of a neighboring base station. For example, the beam information of the first beam can be used by the neighboring base station to adjust the beam configuration of its second beam. Here, for a regenerative architecture, the neighboring base station is deployed on a neighboring satellite; adjusting the beam of the neighboring base station is equivalent to adjusting the beam of the satellite. Alternatively, for a transparent forwarding architecture, the neighboring base station can adjust its beam by adjusting the signal transmitted between the neighboring base station and the satellite beam.

[0202] In another embodiment, the second beam can also be a beam from a nearby satellite. For example, the beam information of the first beam can be used by the nearby satellite to adjust the beam configuration of the second beam of the nearby satellite. Here, for a transparent forwarding architecture, the beam configuration of the second beam of the nearby satellite can be used by the nearby base station to adjust the beam configuration of the second beam.

[0203] In one embodiment, both the first beam and the second beam can be one or more beams. In embodiments of this disclosure, "multiple" refers to two or more. Here, both the first beam and the second beam can include a transmit beam and / or a receive beam; the transmit beam can be at least one, and / or the receive beam can be at least one. Also, the first beam and the second beam can include one or more transmit beams, one or more receive beams, or can include a portion of receive beams and a portion of transmit beams.

[0204] In another embodiment, if the UE is an array antenna, then both the first beam and the second beam can be beamformed beams.

[0205] In one embodiment, the positioning signal includes, but is not limited to, at least one of the following: DL-PRS and UL-SRS.

[0206] For example, the second beam after adjusting the beam configuration is used by the neighboring base station to send DL-PRS to the UE, and / or the second beam after adjusting the beam configuration is used by the UE to send UL-SRS to the neighboring base station; thus, the successful transmission of DL-PRS and / or UL-SRS can facilitate the positioning between the neighboring base station and the UE.

[0207] In another embodiment, the positioning signal can also be any positioning-related signal in the NTN network; for example, it can be an SSB; no limitation is made on the positioning signal here.

[0208] In one embodiment, the positioning signal can be used for at least one of the following positioning methods: UL-TDOA positioning, DL-TDOA positioning, Multi-RTT positioning, DL-AOD positioning, and UL-AOA positioning. Thus, the beam adjustment of neighboring base stations and / or neighboring satellites in this embodiment can be adapted to positioning scenarios such as UL-TDOA positioning, DL-TDOA positioning, Multi-RTT positioning, DL-AOD positioning, and / or UL-AOA positioning, thereby adapting to a wider range of application scenarios.

[0209] Thus, in this embodiment of the disclosure, the LMF sends a request message to the serving base station, wherein the request message is used to request the beam information of the first beam of the serving base station; the beam information of the first beam is used by the neighboring base station to adjust the beam configuration of the second beam, and the adjusted second beam is used for the transmission of positioning signals between the neighboring base station and the UE. In this way, the LMF or the base station (e.g., the neighboring base station) can control the beam configuration (e.g., beam pointing) of the beams of the neighboring base station and / or the neighboring satellite, enabling the neighboring base station and the UE to receive positioning signals sent by each other, thereby enabling positioning measurement or location verification of the UE between the neighboring base station and the UE; that is, it can improve the reliability of positioning signal transmission between the neighboring base station and the UE, and can help improve the accuracy of UE positioning and the correctness of UE location verification.

[0210] It should be noted that those skilled in the art will understand that the methods provided in the embodiments of this disclosure can be executed alone or together with some methods in the embodiments of this disclosure or some methods in related technologies.

[0211] In some embodiments, sending request information to the serving base station in step S41 includes: sending request information to the serving base station based on receiving first identification information of a neighboring base station sent by the UE. Here, the first identification information is sent by the UE after it has not received a downlink signal from a neighboring base station.

[0212] like Figure 5 As shown, this disclosure provides an information processing method, executed by an LMF, comprising:

[0213] Step S50: Receive the first identification information of the neighboring base station sent by the UE;

[0214] Step S51: Send request information to the serving base station based on the first identification information.

[0215] In some possible implementations of this disclosure, the UE may send first identification information of a neighboring base station to the LFM. In some embodiments, the first identification information includes at least one of the following:

[0216] Physical Cell Identifier (PCI);

[0217] Cell Global Identifier (GCI);

[0218] Transmitter Receiver Point (TRP) identifier.

[0219] In this way, the UE informs the LMF about information about neighboring base stations, so that the LMF can subsequently interact with the corresponding neighboring base stations.

[0220] In some embodiments of this disclosure, the request information can be the request information in step S41; the beam information of the first beam can be the beam information of the first beam in step S41.

[0221] In one embodiment, the first identification information is sent by the UE after it has not received a downlink signal from a neighboring base station.

[0222] In another embodiment, the first identification information is sent by the UE after it has not received a downlink signal from a neighboring base station within a predetermined time. Here, the predetermined time may be pre-configured by the UE, determined based on historical experience information, or determined based on negotiation between the UE and the base station (e.g., the serving base station or neighboring base stations).

[0223] In one embodiment, the first identification information includes, but is not less than, at least one of the following: PCI, GCI, and TRP identifier. Here, the TRP identifier can be used to uniquely identify the TRP.

[0224] In this way, by receiving these first identification information from neighboring base stations, the LMF can know which one or more neighboring base stations cannot receive the positioning signal (e.g., UL-SRS).

[0225] This disclosure provides an information processing method executed by an LMF, comprising: receiving response information sent by a serving base station, wherein the response information is used to indicate beam information of a first beam.

[0226] In one embodiment, receiving response information sent by the serving base station can be: receiving response information sent by the serving base station via the NRPPa protocol.

[0227] Here, the response information is determined based on the request information. That is, the LMF sends the request information as described above to the serving base station, and the serving base station sends the development information to the LMF based on the received request information.

[0228] Thus, in this embodiment of the disclosure, the LMF can obtain the beam information of the first beam by receiving the beam information of the first beam sent by the serving base station. This is beneficial for subsequently sending the beam information of the first beam to a neighboring base station to control the beam configuration of the second beam.

[0229] This disclosure provides an information processing method executed by an LMF (Light Filter Function), comprising: receiving beam information of a first beam transmitted by a serving base station. Thus, the LMF can also directly receive the beam information of the first beam.

[0230] This disclosure provides an information processing method executed by an LMF, comprising: sending first indication information to a neighboring base station, wherein the first indication information is used to indicate the beam information of a first beam.

[0231] Here, the first indication information can be one or more bits of information.

[0232] Thus, in this embodiment of the disclosure, it is advantageous for a neighboring base station to receive the first indication information to obtain the beam information of the first beam, thereby facilitating the neighboring base station or neighboring satellite to adjust the beam configuration of the second beam based on the beam information of the first beam, and then successfully complete the transmission of positioning signals between the neighboring satellite and the UE or the neighboring base station and the UE based on the adjusted second beam.

[0233] This disclosure provides an information processing method executed by an LMF (Light Filter Function), comprising: sending beam information of a first beam to a neighboring base station. In this embodiment, the LMF sends a request message to the serving base station, the request message requesting the beam information of the first beam from the serving base station; after receiving the beam information of the first beam sent by the serving base station, the LMF sends the beam information of the first beam to the neighboring base station. Thus, the LMF can also directly send the beam information of the first beam to the neighboring base station.

[0234] It should be noted that those skilled in the art will understand that the methods provided in the embodiments of this disclosure can be executed alone or together with some methods in the embodiments of this disclosure or some methods in related technologies.

[0235] In some embodiments, the LMF sends a request message to the serving base station; wherein the request message includes first identification information, and the request message is used to request first configuration information of the beam information of the first beam of the serving base station; wherein the first configuration information is used by a neighboring base station to receive the beam information of the first beam sent by the serving base station.

[0236] This disclosure provides an information processing method executed by an LMF, comprising: sending a request message to a serving base station, wherein the request message includes first identification information; the request message is used for first configuration information sent by the serving base station, and the first configuration information is used to instruct a neighboring base station to receive beam information of a first beam sent by the serving base station.

[0237] This disclosure provides an information processing method executed by an LMF, comprising: receiving first configuration information sent by a serving base station; and sending the first configuration information to a neighboring base station.

[0238] For example, after receiving the first identification information of a neighboring base station sent by the UE, the LMF determines, based on the first identification information, that the neighboring base station corresponding to the first identification information cannot receive the positioning signal sent by the UE. The LMF sends a request message including the first identification information to the serving base station to request first configuration information, wherein the first configuration information is used to instruct the neighboring base station to receive the beam information of the first beam sent by the serving base station. The LMF receives the first configuration information sent by the serving base station based on the request message and sends the first configuration information to the neighboring base station. In this way, the neighboring base station can directly receive the beam information of the first beam sent by the serving base station based on the first configuration information.

[0239] Thus, in this embodiment of the disclosure, a neighboring base station can also obtain the first configuration information of the beam information of the first beam sent by the serving base station, so as to directly obtain the beam information of the first beam sent by the serving base station; thus, there is no need for the LMF to forward the beam information of the first beam, thereby reducing the waste of transmission resources.

[0240] Furthermore, in this embodiment, the LMF sends a request message after receiving the first identification information. This means that the LMF can control the configuration information of the second beam (e.g., control the direction of the second beam) only after determining that the neighboring base station cannot receive the positioning signal sent by the UE, so as to enable the transmission of the positioning signal between the neighboring base station and the UE. In this way, the transmission of the positioning signal between the neighboring base station and the UE can be improved without the need to control the configuration information of the second beam in real time, thereby reducing the power consumption of the neighboring base station, etc.

[0241] It should be noted that those skilled in the art will understand that the methods provided in the embodiments of this disclosure can be executed alone or together with some methods in the embodiments of this disclosure or some methods in related technologies.

[0242] This disclosure provides an information processing method executed by an LMF, comprising: sending second indication information to a neighboring base station, wherein the second indication information is used to indicate the beam configuration of the second beam to be restored after the positioning measurement is completed.

[0243] Here, the second indication information can be one or more bits.

[0244] For example, the second indication information can be used to indicate whether the positioning measurement is completed; for instance, when the second indication information is a first value, it is used to indicate that the positioning measurement is completed, or when the second indication information is a second value, it is used to indicate that the positioning measurement is not completed.

[0245] For example, the second indication information can be used to indicate the beam configuration for restoring the second beam; for instance, when the second indication information is a third value, it is used to indicate the beam configuration for restoring the second beam, or when the second indication information is a fourth value, it is used to indicate the beam configuration for not restoring the second beam. Here, the third value can be the same as or different from the first value; the fourth value can be the same as or different from the second value.

[0246] Here, the beam configuration of the second beam is restored, that is, the beam configuration of the second beam is restored to the beam configuration before adjustment based on the beam information of the first beam. For example, the beam configuration of the second beam is the same as the beam configuration of the first beam; after adjusting the beam configuration of the second beam based on the beam information of the first beam, the beam configuration of the second beam is the same as the first beam configuration; after the positioning measurement is completed, the beam configuration of the first beam is restored, that is, the beam configuration of the second beam is adjusted to the first beam configuration.

[0247] Thus, in this embodiment of the disclosure, the beam configuration of the second beam can be restored after the positioning measurement is completed, which is beneficial for nearby base stations or nearby satellites to perform other transmission operations based on the second beam before adjustment.

[0248] It should be noted that those skilled in the art will understand that the methods provided in the embodiments of this disclosure can be executed alone or together with some methods in the embodiments of this disclosure or some methods in related technologies.

[0249] The following information processing method is executed by the UE and is similar to the information processing method executed by the LMF described above. For technical details not disclosed in the embodiments of the information processing method executed by the UE, please refer to the description of the information processing method example executed by the LMF, which will not be described in detail here.

[0250] like Figure 6 As shown, this disclosure provides an information processing method, executed by a UE, including:

[0251] Step S61: Send the first identification information of the neighboring base station to the LMF; wherein, the first identification information is used by the LMF to send request information to the serving base station;

[0252] The request information is used to request the beam information of the first beam of the serving base station; the beam information of the first beam is used by the neighboring base station to adjust the beam configuration of the second beam; the second beam after adjusting the beam configuration is used for the transmission of positioning signals between the neighboring base station and the UE.

[0253] In some embodiments of this disclosure, LMF, UE, serving base station and neighboring base station can be LMF, UE, serving base station and neighboring base station as described in the above embodiments; first identification information can be first identification information as described in the above embodiments; service request can be service request as described in the above embodiments; beam information of the first beam and beam configuration of the second beam can be beam information of the first beam and beam configuration of the second beam as described in the above embodiments; positioning signal can be positioning signal as described in the above embodiments.

[0254] For example, the first identification information includes, but is not limited to, at least one of the following: PCI, GCI, and TRP identification.

[0255] For example, the positioning signal can be used for at least one of the following positioning methods: UL-TDOA positioning, DL-TDOA positioning, and Multi-RTT positioning. For example, the positioning signal can be used for at least one of the following positioning methods: DL-AOD positioning and UL-AOA positioning.

[0256] For example, the positioning signal includes, but is not limited to, at least one of the following: DL-PRS, UL-SRS, and SBB.

[0257] For example, the beam information of the first beam may be, but is not limited to, information related to the geographical location of the first beam and / or information related to the direction of the first beam. For instance, the beam information of the first beam includes, but is not limited to, the location information of the beam center point of the first beam and / or the direction of at least one beam of the first beam.

[0258] For example, the beam configuration of the second beam includes, but is limited to, at least one of the following: the geographical location of at least one beam in the second beam, the number of second beams, the direction of at least one beam in the second beam, and the coverage area of ​​at least one beam in the second beam.

[0259] In some embodiments, sending the first identification information of the neighboring base station to the LMF in step S61 includes: sending the first identification information of the neighboring base station to the LMF based on the fact that no downlink signal sent by the neighboring base station has been received.

[0260] This disclosure provides an information processing method executed by a UE, including: sending first identification information of a neighboring base station to an LMF based on the fact that no downlink signal has been received from a neighboring base station.

[0261] In some embodiments, sending the first identification information of the neighboring base station to the LMF in step S61 includes: sending the first identification information of the neighboring base station to the LMF based on the fact that no downlink signal sent by the neighboring base station has been received within a predetermined time.

[0262] This disclosure provides an information processing method executed by a UE, including: sending first identification information of a neighboring base station to an LMF based on the fact that no downlink signal is received from a neighboring base station within a predetermined time.

[0263] Here, the signal transmission between the neighboring base station and the UE can be either direct transmission between the neighboring base station and the UE, or signal transmission between the neighboring base station and the UE via relay from a neighboring satellite.

[0264] Thus, in this embodiment of the disclosure, if no downlink signal is received from a neighboring base station (within a predetermined time), it is determined that the UE may not receive a positioning signal (e.g., DL-PRS) from the neighboring base station. This predetermined time can be specified by a protocol, pre-configured, or configured as needed via other signaling.

[0265] This disclosure provides an information processing method executed by a UE, including: determining not to send UL-SRS to a neighboring base station. If the UE does not receive a positioning signal (e.g., DL-PRS) sent by a neighboring base station, the UE will not send UL-SRS to the neighboring base station, thus reducing UE power consumption and lowering the failure rate of sending UL-SRS. This method can be adapted to scenarios of UL-TDOA positioning, DL-TDOA positioning, and / or Multi-RTT positioning.

[0266] This disclosure provides an information processing method, executed by a UE, including:

[0267] Obtain second configuration information, wherein the second configuration information is used to indicate the configuration of the uplink detection reference signal UL-SRS and / or SSB;

[0268] Receive downlink signals sent by neighboring base stations based on the second configuration information.

[0269] In some embodiments, obtaining the second configuration information includes:

[0270] Receive second configuration information sent by the serving base station, wherein the second configuration information is used to indicate the configuration of UL-SRS;

[0271] And / or,

[0272] Receive second configuration information of neighboring base stations sent by LMF, wherein the second configuration information is used to indicate the configuration of SSB.

[0273] This disclosure provides an information processing method, executed by a UE, including:

[0274] Receive second configuration information sent by the serving base station, wherein the second configuration information is used to indicate the configuration of UL-SRS;

[0275] Receive downlink signals sent by neighboring base stations based on the second configuration information.

[0276] For example, the UE receives second configuration information sent by the LMF serving base station, which is used to indicate the configuration of UL-SRS; the UE receives downlink signals sent by neighboring base stations based on the second configuration information; if the UE does not receive downlink signals sent by neighboring base stations within a predetermined time, it determines not to send UL-SRS to neighboring base stations, and sends the first identification information of the neighboring base station to the serving base station.

[0277] This disclosure provides an information processing method, executed by a UE, including:

[0278] Receive second configuration information of neighboring base stations sent by the LMF, wherein the second configuration information is used to indicate the configuration of the SSB.

[0279] Receive downlink signals sent by neighboring base stations based on the second configuration information.

[0280] For example, the UE receives the second configuration information of the neighboring base station sent by the LMF. The second configuration information is used to indicate the configuration of the SSB. The second configuration information is sent by the neighboring base station to the LMF. The UE receives the downlink signal sent by the neighboring base station based on the second configuration information. If the UE does not receive the downlink signal sent by the neighboring base station within a predetermined time, the UE will not send UL-SRS to the neighboring base station, and the serving base station will send the first identification information of the neighboring base station.

[0281] It should be noted that those skilled in the art will understand that the methods provided in the embodiments of this disclosure can be executed alone or together with some methods in the embodiments of this disclosure or some methods in related technologies.

[0282] This disclosure provides an information processing method, executed by a UE, including: sending UL-SRS to a nearby base station. This can be adapted to scenarios involving UL-TDOA positioning and / or Multi-RTT positioning.

[0283] For example, the UE receives a downlink signal from a neighboring signal and sends a UL-SRS to the neighboring base station; or, the UE (within a predetermined time) does not receive a downlink signal from a neighboring signal and sends a UL-SRS to the neighboring base station. Here, when the neighboring base station does not receive the UL-SRS sent by the UE, the neighboring base station sends an indication that it has not received the UL-SRS sent by the UE to the LMF; thus, the LMF requests the beam information of the first beam or first configuration information indicating the beam information of the first beam and sends it to the neighboring base station.

[0284] In this embodiment of the disclosure, the UE performs UL-SRS transmission regardless of whether it receives a downlink signal from a neighboring base station.

[0285] It should be noted that those skilled in the art will understand that the methods provided in the embodiments of this disclosure can be executed alone or together with some methods in the embodiments of this disclosure or some methods in related technologies.

[0286] This disclosure provides an information processing method, executed by a UE, including:

[0287] Receive SSB and / or downlink positioning reference signal (DL-PRS) signals transmitted by a neighboring base station based on the second beam after adjusting the beam configuration;

[0288] Based on the second beam after adjusting the beam configuration, the third beam for the UE to transmit UL-SRS is determined.

[0289] Here, the second and third beams form a beam pair. Thus, a nearby base station and the UE can transmit positioning signals via the beam pair. For example, the UE can send UL-SRS to a nearby base station based on the third beam to increase the probability that the nearby base station or a nearby satellite will receive the UL-SRS.

[0290] For details of the above implementation methods, please refer to the description on the LMF side, which will not be repeated here.

[0291] It should be noted that those skilled in the art will understand that the methods provided in the embodiments of this disclosure can be executed alone or together with some methods in the embodiments of this disclosure or some methods in related technologies.

[0292] The following information processing method is performed by the serving base station and is similar to the information processing method performed by the LMF and / or UE described above. For technical details not disclosed in the embodiments of the information processing method performed by the serving base station, please refer to the description of the information processing method example performed by the LMF and / or UE, which will not be described in detail here.

[0293] like Figure 7 As shown, this embodiment of the disclosure provides an information processing method, executed by a serving base station, including:

[0294] Step S71: Receive the request information sent by the LMF, wherein the request information is used to request the beam information of the first beam of the serving base station;

[0295] The beam information of the first beam is used by the neighboring base station to adjust the beam configuration of the second beam; the second beam after adjusting the beam configuration is used for the transmission of positioning signals between the neighboring base station and the UE.

[0296] In some embodiments of this disclosure, LMF, UE, serving base station and neighboring base station can be LMF, UE, serving base station and neighboring base station as described in the above embodiments; service request can be service request as described in the above embodiments; beam information of the first beam and beam configuration of the second beam can be beam information of the first beam and beam configuration of the second beam as described in the above embodiments; positioning signal can be positioning signal as described in the above embodiments.

[0297] For example, the positioning signal can be used for at least one of the following positioning methods: UL-TDOA positioning, DL-TDOA positioning, and Multi-RTT positioning. For example, the positioning signal can be used for at least one of the following positioning methods: DL-AOD positioning and UL-AOA positioning.

[0298] For example, the positioning signal includes, but is not limited to, at least one of the following: DL-PRS, UL-SRS, and SBB.

[0316] For example, the beam information of the first beam may be, but is not limited to, information related to the geographical location of the first beam and / or information related to the direction of the first beam. For instance, the beam information of the first beam includes, but is not limited to, the location information of the beam center point of the first beam and / or the direction of at least one beam of the first beam.

[0320] In some embodiments, step S81 includes: receiving first indication information sent by the LMF, wherein the first indication information is used to indicate the beam information of the first beam.

[0321] This disclosure provides an information processing method executed by a neighboring base station, comprising: receiving first indication information sent by an LMF, wherein the first indication information is used to indicate beam information of a first beam.

[0322] This disclosure provides an information processing method executed by a neighboring base station, comprising: receiving beam information of a first beam transmitted by an LMF.

[0323] In this way, a neighboring base station can obtain the beam information of the first beam sent by the serving base station through the first indication information forwarded by the LMF, or it can obtain the beam information of the first beam sent by the serving base station through the LMF.

[0324] In some embodiments, the method includes: receiving first configuration information sent by the LMF;

[0325] Step S81 includes: receiving beam information of the first beam sent by the serving base station based on the first configuration information.

[0326] This disclosure provides an information processing method, executed by a neighboring base station, including:

[0327] Receive the first configuration information sent by LMF;

[0328] Based on the first configuration information, receive the beam information of the first beam sent by the serving base station.

[0329] In this way, a neighboring base station can receive the first configuration information of the serving base station regarding the beam information of the first beam, and directly receive the beam information of the serving base station's first beam based on the first configuration information.

[0330] In one embodiment, adjusting the beam configuration of the second beam of a neighboring base station based on the beam information of the first beam in step S82 can be: adjusting the beam configuration of the beams of a neighboring satellite based on the beam information of the first beam.

[0331] Here, the second beam can be a beam from a nearby base station, or the second beam can be a beam from a nearby satellite.

[0332] This disclosure provides an information processing method executed by a neighboring base station, comprising: sending a DL-PRS to a UE based on a second beam configured with adjusted beams; and / or receiving a UL-SRS sent by the UE based on the second beam configured with adjusted beams. Here, the UL-SRS may also be sent by the UE based on a third beam, which is a beam pair with the second beam.

[0333] It should be noted that those skilled in the art will understand that the methods provided in the embodiments of this disclosure can be executed alone or together with some methods in the embodiments of this disclosure or some methods in related technologies.

[0334] In some embodiments, before step S81, the method further includes: sending a downlink signal to the UE. Here, the neighboring base station sends the downlink signal to the UE before step S81, that is, it sends the downlink signal to the UE by adjusting the second beam before the beam.

[0335] This disclosure provides an information processing method executed by a neighboring base station, comprising: sending a downlink signal to a UE based on a second beam before beam configuration adjustment. Here, the downlink signal is used to send request information to the serving base station when the base station does not receive it; the request information is used to request beam information of the first beam.

[0336] In some embodiments, before sending the downlink beam to the UE, the method further includes sending second configuration information of a neighboring base station to the LMF.

[0337] This disclosure provides an information processing method executed by a neighboring base station, comprising: sending second configuration information of the neighboring base station to an LMF, wherein the second configuration information is used by the LMF to send to a UE, and the second configuration information is used to indicate the configuration of the SSB.

[0338] In some embodiments, the neighboring base station is a base station in a regenerative architecture;

[0339] The method includes: adjusting the transmission power to a predetermined transmission power; and transmitting a downlink signal based on the predetermined transmission power.

[0340] This disclosure provides an information processing method executed by a neighboring base station, comprising: adjusting the transmission power to a predetermined transmission power; and transmitting a downlink signal based on the predetermined transmission power.

[0341] In one embodiment, the predetermined transmit power is a power greater than or equal to a first power. For example, the predetermined transmit power is greater than 22 dBm or 23 dBm, etc.

[0342] In another embodiment, the predetermined transmission power is the maximum transmission power. For example, the maximum transmission power is 23 dBm.

[0343] Thus, for a neighboring base station or a neighboring satellite in the regeneration architecture, the transmit power of the neighboring base station or neighboring satellite can be adjusted to the maximum transmit power (23dBm); if the UE has not yet received the downlink signal sent by the neighboring base station or neighboring satellite, it is assumed that the neighboring base station or neighboring satellite also cannot receive the UL-SRS sent by the UE.

[0344] For nearby base stations or nearby satellites in the transparent forwarding architecture, because the path loss and reception gains of the feeder link and service link are inconsistent, whether the UE can receive the downlink signal of the nearby base station cannot be used as a criterion for whether UL-SRS transmission can be received by the nearby satellite or nearby base station.

[0345] It should be noted that those skilled in the art will understand that the methods provided in the embodiments of this disclosure can be executed alone or together with some methods in the embodiments of this disclosure or some methods in related technologies.

[0346] In some embodiments, step S8, adjusting the beam configuration of the second beam of a neighboring base station based on the beam information of the first beam, includes:

[0347] For a neighboring base station in a transparent forwarding architecture, after determining that a neighboring satellite can receive the signal from the neighboring base station, the beam configuration of the second beam is adjusted based on the beam information of the first beam.

[0348] And / or,

[0349] For neighboring base stations of the regenerative architecture, after obtaining the beam information of the first beam, the beam configuration of the second beam is adjusted based on the beam information of the first beam.

[0350] This disclosure provides an information processing method executed by a neighboring base station in a transparent forwarding architecture, comprising: after determining that a neighboring satellite can receive signals from the neighboring base station, adjusting the beam configuration of a second beam based on the beam information of a first beam. Here, in the transparent forwarding architecture, since the neighboring base station and the neighboring satellite are not in the same location, it is necessary to determine that the neighboring satellite can receive signals (e.g., downlink signals) from the neighboring base station before adjusting the beam configuration of the second beam. This ensures that signals transmitted between the neighboring base station and the UE can be forwarded through the neighboring satellite.

[0351] This disclosure provides an information processing method executed by a neighboring base station in a regenerative architecture, comprising: after acquiring the beam information of a first beam, adjusting the beam configuration of a second beam based on the beam information of the first beam. Here, in the regenerative architecture, since the neighboring base station is on a neighboring satellite, directly adjusting the beam configuration of the second beam in this way can also ensure that the signal transmitted between the neighboring base station and the UE can be forwarded by the neighboring satellite.

[0352] It should be noted that those skilled in the art will understand that the methods provided in the embodiments of this disclosure can be executed alone or together with some methods in the embodiments of this disclosure or some methods in related technologies.

[0353] This disclosure provides an information processing method, executed by a neighboring base station, including:

[0354] Receive the second instruction information sent by LMF;

[0356] In some embodiments of this disclosure, the second indication information may be the second indication information described in the above embodiments. For example, the second indication information may be used to indicate the completion of positioning-side measurements and / or to indicate the beam configuration for recovering the second beam.

[0373] The UE is configured to send the first identification information of the neighboring base station to the LMF if it does not receive a downlink signal from the neighboring base station within a predetermined time.

[0374] For details of the above implementation methods, please refer to the descriptions on the LMF and / or UE and / or serving base station and / or neighboring base station sides, which will not be repeated here.

[0375] It should be noted that those skilled in the art will understand that the apparatus provided in the embodiments of this disclosure can be executed alone or together with some apparatus in the embodiments of this disclosure or some apparatus in related technologies.

[0376] Regarding the apparatus in the above embodiments, the specific manner in which each module performs its operation has been described in detail in the embodiments related to the method, and will not be elaborated upon here.

[0377] To further explain any of the embodiments of this disclosure, several specific embodiments are provided below.

[0378] Example 1:

[0379] This disclosure provides an information processing method executed by a communication device, which includes an LMF, a UE, a neighboring base station, and / or a serving base station; the information processing method includes the following steps:

[0380] Step 1: The UE determines that it cannot receive downlink signals transmitted by a nearby base station (or nearby satellite); this step 1 may include the following two situations:

[0381] Scenario 1:

[0382] Upon receiving second configuration information from the serving base station, which indicates the configuration of UL-SRS, or upon receiving second configuration information from the LMF from a neighboring base station, which indicates the configuration of SSB, the UE begins receiving downlink signals from the neighboring base station based on the second configuration information. If the UE does not receive downlink signals from the neighboring base station within a predetermined time, it determines that it cannot receive downlink signals from the neighboring base station and determines not to send UL-SRS to the neighboring base station; the UE sends the first identification information of the neighboring base station to the LMF via the LTE Positioning Protocol (LPP), wherein the first identification information includes PCI, GCI, and / or TRP identifiers.

[0383] For example, in UL-TDOA positioning, the LMF will indicate the SSB configuration information of the neighboring base station to the serving base station when requesting UL-SRS transmission characteristic information.

[0384] For example, in a regenerative architecture, a nearby base station or satellite can adjust its transmit power to the UE's maximum transmit power (23dBm) and transmit downlink signals based on this maximum transmit power. If the UE does not receive downlink signals from a nearby base station or satellite, it can be assumed that the nearby base station or satellite also cannot receive UL-SRS signals. This method of adjusting the transmit power to the maximum transmit power to transmit downlink signals is suitable for a regenerative architecture.

[0385] Scenario 2: Regardless of whether the UE receives downlink signals from neighboring base stations, the UE sends UL-SRS to the neighboring base stations. If a neighboring base station does not receive the UL-SRS sent by the UE, the neighboring base station sends information indicating that it has not received UL-SRS to the LMF via the NRPPa protocol.

[0386] UL-TDOA positioning and / or Multi-RTT positioning can be adapted to both Case 1 and Case 2; or, DL-TDOA positioning and / or Multi-RTT positioning can be adapted to Case 1.

[0387] Step 2: Information exchange between the LMF and the base station (serving base station and / or neighboring base stations) to control the beam configuration of the second beam; this second step includes the following two cases:

[0388] Scenario 1:

[0389] Based on the received first identification information, the LMF determines neighboring base stations that cannot receive UL-SRS. The LMF sends a request message to the serving base station via the NRPPa protocol, requesting beam information (e.g., the geographical location of the first beam) for the serving base station. The serving base station sends a response message indicating the beam information of the first beam to the LMF via the NRPPa protocol, or sends the beam information of the first beam. The LMF sends a first indication message indicating the beam information of the first beam to the neighboring base stations, or sends the beam information of the first beam. Based on the beam information of the first beam, the neighboring base stations adjust the configuration information of the second beam.

[0390] For example, if the UE is an array antenna, the first and second beams can be beamformed. After receiving SSB and / or DL-PRS transmitted by a neighboring base station or a neighboring satellite, the UE can obtain a beam pair with the best direction to the neighboring base station or neighboring satellite (for example, the third beam in the above embodiment); and transmit UL-SRS based on the third beam pair to increase the satellite's reception power of UL-SRS.

[0391] For example, the beam information transmitted by the serving base station for the first beam may be, but is not limited to, the location information of the center point of the beam transmitting the first beam and / or the direction of at least one beam.

[0392] For example, for a neighboring base station in a transparent forwarding architecture, after determining that a neighboring satellite can receive the signal from the neighboring base station, the beam configuration of the second beam is adjusted based on the beam information of the first beam; and / or, for a neighboring base station in a regenerative architecture, after obtaining the beam information of the first beam, the beam configuration of the second beam is adjusted based on the beam information of the first beam.

[0393] Scenario 2:

[0394] Based on the received first identification information, the LMF determines neighboring base stations that cannot receive UL-SRS. The LMF sends a request message to the serving base station via the NRPPa protocol. The request message includes the first identification information and is used to request the first configuration information of the serving base station's first beam (e.g., the geographical location of the first beam). The serving base station sends the first configuration information to the LMF via the NRPPa protocol. The LMF sends indications of the first configuration information to neighboring base stations. The neighboring base stations directly receive the beam information of the first beam sent by the serving base station based on the first configuration information and adjust the configuration information of the second beam based on the beam information of the first beam.

[0395] For example, if the UE is an array antenna, the first and second beams can be beamformed. After receiving SSB and / or DL-PRS transmitted by a neighboring base station or a neighboring satellite, the UE can obtain a beam pair with the best direction to the neighboring base station or neighboring satellite (for example, the third beam in the above embodiment); and transmit UL-SRS based on the third beam pair to increase the satellite's reception power of UL-SRS.

[0396] For example, for a neighboring satellite with a transparent relay architecture, after determining that the neighboring satellite can also receive signals from a neighboring base station, the beam configuration information of the neighboring satellite is adjusted based on the beam information of the first beam; and / or, for a neighboring satellite with a regenerative architecture, signals can be transmitted via Starlink (i.e., inter-satellite links).

[0397] Step 3: Positioning ends, and each neighboring base station restores the beam configuration of the second beam to its original state; Step 3 includes: after the LMF determines that the positioning measurement is completed, the LMF sends a second indication information to the neighboring base stations, the second indication information indicating that the beam configuration of the second beam is restored after the positioning measurement is completed; based on the second indication information, the neighboring base stations restore the beam configuration of the second beam to its original state.

[0398] For example, for a neighboring base station in a transparent forwarding architecture, the neighboring base station instructs a neighboring satellite to restore the beam configuration of the second beam (e.g., the neighboring base station sends a second instruction message to the neighboring satellite); and / or, for a regeneration architecture, the neighboring base station directly restores the beam configuration of the second beam.

[0399] The first, second, and third steps of the embodiments of this disclosure are all applicable to UL-TDOA positioning or Multi-RTT positioning; except for the second case in the first step which is not applicable to DL-TDOA positioning, all other cases in the embodiments of this disclosure are applicable to DL-TDOA positioning.

[0400] Example 2

[0401] like Figure 9 As shown, this disclosure provides an information processing method executed by a communication device, which includes an LMF, a UE, a neighboring base station, and / or a serving base station; the information processing method includes the following steps:

[0402] Here, the steps performed by the serving base station can also be performed by the TRP of the serving base station; the steps performed by the neighboring base station can also be performed by the TRP of the neighboring base station.

[0403] Step S900: The neighboring base station or the serving base station exchanges third configuration information with the LMF through the NRPPa protocol, so that the LMF, the neighboring base station or the serving base station can obtain the third configuration information;

[0404] Here, the third configuration information may be, but is not limited to, the second configuration information mentioned above and / or the first identification information of the neighboring base station and / or the location-related configuration information.

[0405] Step S901: The LMF obtains the UE's positioning capability through the LPP protocol;

[0406] Step S902: The LMF requests the serving base station to configure the UE's UL-SRS via the NRPPa location request information;

[0407] Here, the LMF can also indicate the SSB configuration of other base stations (e.g., base stations other than the serving base station) to the serving base station for path loss estimation;

[0408] Here, the configuration of UL-SRS and / or SSB can be indicated by the second configuration information in the above embodiments.

[0409] Here, the NRPPa location request information can be an NRPPa POSITIONING INFORMATION REQUEST.

[0410] Step S903: The serving base station determines the resource configuration of UL-SRS and sends it to the UE;

[0411] Step S904: The serving base station transmits the U-SRS configuration to the LMF via the NRPPa positioning response information;

[0412] Here, the NRPPa positioning response information can be NRPPa POSITIONING INFORMATION RESPONSE.

[0413] Step S905: The UE detects downlink signals (e.g., SSB) sent by neighboring base stations; if downlink signals from all neighboring base stations are detected, the normal positioning measurement process is performed; if downlink signals from some neighboring base stations are not detected, the UE sends the PCI, GCI, and / or TRP identifiers of those neighboring base stations to the LMF.

[0414] Here, if step S905 uses "case one" of "step one" in the above embodiments, then "case two" of "step one" in the above embodiments is ignored.

[0415] Step S906A: The LMF sends an NRPPa location activation request message to the serving base station to request activation of UL-SRS transmission;

[0416] Here, the NRPPa Positioning Activation Request message can be an NRPPa Positioning Activation Request message.

[0417] Here, in a non-periodic or semi-static configuration, the LMF sends an NRPPa location activation request message to the serving base station.

[0418] Step S906B: The serving base station sends an NRPPa location activation request message to the UE;

[0419] Step S906C: The serving base station activates UL-SRS transmission and sends an NRPPa location activation response message to the LMF;

[0420] Here, the NRPPa positioning activation response message can be an NRPPa Positioning Activation Response message.

[0421] Here, the UE starts transmitting UL-SRS according to the time domain configured by the UL-SRS resources, or the UE does not transmit UL-SRS.

[0422] Step S907: The LMF sends the UL-SRS configuration to the serving base station that needs to perform positioning measurements;

[0423] Here, LMF can also send the information required for UL-SRS measurement to the service base station that needs to perform positioning measurement via NRPPa measurement request.

[0424] Step S908: If the neighboring base station does not detect UL-SRS, it sends the first identification information of the neighboring base station to the LMF;

[0425] Here, the first identification information includes at least one of the following: PCI, GCI, and TRP identification.

[0426] Step S909: The serving base station sends a request message to the LMF via the NRPPa protocol. The request message is used to request the beam information of the first beam.

[0427] Step S910: The serving base station sends a response message to the LMF via NRPPa. The response message is used to indicate the beam information of the first beam.

[0428] Step S911: The LMF sends a first indication message to a neighboring base station that cannot receive UL-SRS via the NRPPa protocol. The first indication message is used to indicate the beam information of the first beam.

[0429] In an optional embodiment, the method includes the following steps (steps S912 to S915):

[0430] Step S912: The LMF sends a request message to the neighboring base station via the NRPPa protocol. The request message includes the first identification information of the neighboring base station that cannot receive UL-SRS, and the first configuration information of the beam information of the first beam is used to request the beam information of the first beam.

[0431] Step S913: The serving base station sends the first configuration information to the LMF;

[0432] Step S914: The first configuration information of LMF is sent to the neighboring base station that cannot receive UL-SRS;

[0433] Step S915: The beam information of the first beam of the serving base station is sent to a neighboring base station that cannot receive UL-SRS;

[0434] Step S916: The neighboring base station adjusts the configuration information of the second beam based on the beam information of the first beam;

[0435] Step S917: The neighboring base station and / or serving base station perform positioning measurement operations with the LMF;

[0436] Step S918: After the location is completed, the LMF sends an NRPPa location deactivation message to the serving base station;

[0437] Here, the NRPPa POSITIONING DEACTIVATION message can be the NRPPa POSITIONING DEACTIVATION message.

[0438] Step S919: The LMF indicates via NRPPa that the positioning measurement of the neighboring base station has been completed and restores the beam configuration of the second beam.

[0439] Thus, the embodiments of this disclosure can solve the problem in satellite communication where the distance between multiple satellites in a satellite constellation is large, causing the UE and neighboring base stations to be unable to receive downlink and / or uplink signals. This is beneficial for improving the accuracy of UE positioning measurements or verifying the correctness of the UE's location.
