[0199] In the embodiments of this application, the term "and / or" describes the relationship between associated objects, indicating that three relationships can exist. For example, A and / or B can represent three cases: A alone, A and B simultaneously, and B alone. The character " / " generally indicates that the preceding and following associated objects have an "or" relationship.

[0200] In the embodiments of this application, the term "multiple" refers to two or more, and other quantifiers are similar.

[0201] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0202] See Figure 1 , Figure 1This is a flowchart of an information processing method provided in an embodiment of this application, applied to a terminal. For example... Figure 1 As shown, it includes the following steps:

[0203] Step 101: Receive first information sent by the network device, wherein the first information is used to instruct the network device on one or more of the following:

[0204] The location of the first sampling point, the first sampling period, the bandwidth used for the first sampling, the configuration of the reference signal for positioning and / or sensing, information on other terminals and / or other network devices involved in positioning and / or sensing the terminal, and resource information for positioning and / or sensing the terminal.

[0205] Wherein, the location of the first sampling point and the first sampling period are used for positioning and / or sensing of the terminal; or

[0206] The information of other terminals and / or other network devices involved in locating and / or sensing the terminal includes at least one of the following:

[0207] The number of other terminals and / or network devices involved in locating and / or sensing the terminal;

[0208] Identifications of other terminals and / or network devices involved in locating and / or sensing the terminal;

[0209] The location of other terminals and / or network devices involved in locating and / or sensing the terminal;

[0210] Alternatively, the resource information used for locating and / or sensing the terminal may include bandwidth size.

[0211] The configuration of reference signals used for positioning and / or sensing may include, for example, the transmission resources occupied by reference symbols.

[0212] In this embodiment, when a UE enters an NTN (Non-terrestrial network), the network device can send system messages or other signaling information to the terminal, carrying the aforementioned first information. Optionally, it may also include bandwidth information of the cell that can be used for positioning and / or sensing, orbit information, and the distance of the satellite's movement curve over a certain period of time.

[0213] Step 102: Based on the first positioning and / or sensing accuracy, send the second information to the network device.

[0214] The second information is used to request an update to the first information. Optionally, the terminal may also receive updated first information sent by the network device.

[0215] In this embodiment of the application, the second information can request an update of one or more pieces of information indicated by the first information, based on the first information. For example, if the first indication information indicates the location of a first sampling point, the second information can be used to request an update of the location of the first sampling point.

[0216] Optionally, the second information may also include the first positioning and / or sensing accuracy.

[0217] Prior to this step, the terminal may acquire initial positioning and / or sensing accuracy.

[0218] Specifically, the terminal can obtain at least one third piece of information from the network device and determine the first positioning and / or sensing accuracy corresponding to the at least one third piece of information. Each piece of third information includes at least one of the following: a first bandwidth, a first SINR, a second sampling period, and antenna parameters. The antenna parameters include: RCS, GA, antenna aperture, etc.

[0219] That is, in the embodiments of this application, the terminal determines whether to send the second information to the network by comparing the calculated first positioning and / or sensing accuracy with the required accuracy or a multiple of the required accuracy.

[0220] Wherein, for each of the third pieces of information, the first positioning and / or sensing accuracy is proportional to the second sampling period, and / or, the first positioning and / or sensing accuracy is inversely proportional to the first bandwidth, the first SINR, and the antenna parameters.

[0221] For example, for target third information, a partial derivative is taken with respect to the second sampling period in the target third information to obtain a first value, wherein the target third information is one or more of the third information. Then, a second value is obtained by taking the partial derivative based on the first bandwidth, the first SINR, and the antenna parameters in the target third information, and the quotient of the first value and the second value is used as the first positioning and / or sensing accuracy corresponding to the target third information.

[0222] Specifically, the first positioning and / or sensing accuracy corresponding to the third information of the target can be determined according to the following formula:

[0223]

[0224] in, Let T represent the second sampling period in the target's third information, BW represent the first bandwidth in the target's third information, SINR represent the first SINR in the target's third information, GA represent the antenna gain in the target's third information, AD represent the antenna aperture in the target's third information, and RCS represent the radar cross section in the target's third information.

[0225] The terminal compares the first positioning and / or sensing accuracy with the second positioning and / or sensing accuracy. If the first positioning accuracy is greater than the second positioning accuracy, and / or if the first sensing accuracy is greater than the second sensing accuracy, the terminal sends second information to the network device, wherein the second positioning and / or sensing accuracy includes a preset positioning and / or sensing accuracy.

[0226] For example, if the first positioning accuracy calculated in the above manner is greater than the preset second positioning accuracy (which may also include a multiple of the second positioning accuracy), the terminal can send second information to the network device, thereby triggering the network device to perform positioning.

[0227] Alternatively, the at least one third piece of information may also include one or more of a third positioning and / or sensing accuracy and a third positioning and / or sensing type. The third positioning and / or sensing accuracy can be one or more positioning and / or sensing accuracies provided by the network device, with different positioning and / or sensing types having their own corresponding positioning and / or sensing accuracy requirements. That is, the network device can provide various configurations, including different bandwidths, SINRs, RCSs, sampling time intervals, antenna gain, and antenna apertures, as well as corresponding accuracy information and positioning and / or sensing types. The terminal can select a suitable configuration based on its own accuracy requirements and supported positioning and / or sensing types, and synchronize with the network device. The bandwidth can be represented as the bandwidth occupied by a set of reference signals used for positioning and / or sensing, or multiple sets of reference signals, or the frequency domain density occupied by the positioning and / or sensing reference signals. In this way, the terminal can more flexibly determine whether to send the first information.

[0228] Specifically, the terminal can compare the first positioning and / or sensing accuracy with one or more of the third positioning and / or sensing accuracy and the positioning and / or sensing accuracy corresponding to the third positioning and / or sensing type, and send the second information to the network device according to the comparison result.

[0229] For example, the terminal can compare a calculated first positioning and / or sensing accuracy with a third positioning and / or sensing accuracy. If the two are consistent or match, the terminal sends second information to the network device; otherwise, the terminal does not send second information. Similarly, the terminal can compare the first positioning accuracy with the third positioning accuracy. If they are consistent or match, the terminal sends the first information to the network device; otherwise, the terminal does not send second information. Likewise, the terminal can compare the first sensing accuracy with the third sensing accuracy. If they are consistent or match, the terminal sends second information to the network device; otherwise, the terminal does not send second information. Furthermore, the terminal can compare the first positioning accuracy with the third positioning accuracy, and also compare the first sensing accuracy with the third sensing accuracy. If both comparison results indicate consistency or match, the terminal sends second information to the network device; if one or both results indicate inconsistency or mismatch, the terminal does not send second information.

[0230] Alternatively, the terminal may compare the calculated first positioning and / or sensing accuracy with the positioning and / or sensing accuracy corresponding to a certain positioning and / or sensing type. If the two are consistent or match, the terminal sends the second information to the network device; if the two are inconsistent or do not match, the terminal does not send the second information to the network device.

[0231] Alternatively, the terminal may compare the first positioning and / or sensing accuracy with the third positioning and / or sensing accuracy and the positioning and / or sensing accuracy corresponding to the third positioning and / or sensing type, and determine whether to send the second information based on the comparison results. The strategy for determining whether to send the second information may depend on the specific implementation of the terminal and is not limited here. For example, sending the second information may be determined if the two comparison results are consistent.

[0232] In this embodiment, the terminal sends first information to the network device. The first information includes one or more of the following: the location of a first sampling point, a first sampling period, the bandwidth used for the first sampling, the configuration of a reference signal for positioning and / or sensing, information on other terminals and / or other network devices participating in positioning and / or sensing the terminal, and resource information for positioning and / or sensing the terminal. This enables the network device to perform positioning and / or sensing based on the first information of the terminal, thereby improving the accuracy of positioning and / or sensing.

[0233] Based on the above embodiments, the terminal can also obtain fourth information from the network device, wherein the fourth information includes sampling point information, which is determined based on the first information. Then, the terminal can merge the sampling points according to the fourth information and send fifth information to the network device, wherein the fifth information includes information about the merged sampling points.

[0234] After receiving the fifth piece of information, the network device can determine the specific location and sampling period of the sampling points based on this information, and then perform sampling to form a series of sampling point information. Whether the sampling point merging is performed at the terminal or the network side can be agreed upon in advance by either the terminal or the network side, or, by default, one side can be used for processing. During the data sampling point merging process, distance errors caused by satellite movement can be deducted.

[0235] When merging sampling points, as the satellite moves, multiple lines (surfaces) can be formed between the satellite and the terminal's positioning and / or between the sensing point and the satellite at different sampling points. The intersection of multiple lines (surfaces) can form a point, and multiple sampling points that form this point can be merged into one sampling point.

[0236] Based on the above embodiments, the terminal can also obtain sixth information from the network device, wherein the sixth information includes information of the merged sampling points, and perform uplink and downlink synchronization based on the sixth information.

[0237] By merging sampling points or synchronizing uplink and downlink based on merged sampling points, positioning and / or sensing accuracy can be further improved and positioning and / or sensing errors reduced.

[0238] See Figure 2 , Figure 2 This is a flowchart of an information processing method provided in an embodiment of this application, applied to a network device, such as... Figure 2 As shown, it includes the following steps:

[0239] Step 201: Send the first message to the terminal.

[0240] The explanation of the first information can be found in the description of the foregoing method embodiments.

[0241] Step 202: Receive the second information sent by the terminal.

[0242] The second information is used to request an update to the first information. Correspondingly, the network device can also send updated first information to the terminal.

[0243] After receiving the second information, the network device can determine whether to adjust the bandwidth, transmit power, sampling interval, etc., based on the second information to obtain updated first information. For example, taking RTT (Round-Trip Time) technology as an example, if the current network device is configured with a bandwidth of BW0, a signal-to-noise ratio of SINR0, a sampling interval of T0, and the antenna gain and antenna aperture are statically configured, and the terminal calculates a first positioning and / or sensing accuracy higher than the required positioning and / or sensing accuracy, the terminal can send the second information to the network device. The network device can then increase the measurement bandwidth used for positioning and / or sensing, increase the transmit power, reduce the sampling interval, etc., thereby improving positioning and / or sensing accuracy and reducing positioning and / or sensing errors.

[0244] Optionally, the network device may also send at least one third piece of information to the terminal, wherein each third piece of information includes at least one of the following: a first bandwidth, a first SINR, a second sampling period, and antenna parameters, so as to facilitate the terminal in determining whether to send the second piece of information.

[0245] Optionally, the at least one third piece of information may further include one or more of the following: third positioning and / or sensing accuracy and third positioning and / or sensing type. That is, the network device can provide various configurations, including different bandwidths, SINRs, RCSs, sampling time intervals, antenna gain, and antenna apertures, as well as corresponding accuracy information and positioning and / or sensing types. The terminal can select a suitable configuration based on its own accuracy requirements and supported positioning and / or sensing types, and synchronize with the network device. The bandwidth can represent the bandwidth occupied by a set of reference signals used for positioning and / or sensing, or multiple sets of reference signals, or the frequency domain density occupied by the positioning and / or sensing reference signals, etc. In this way, the terminal can more flexibly determine whether to send the second information.

[0246] Optionally, the network device may also send a fourth piece of information to the terminal, wherein the fourth piece of information includes sampling point information, which is determined based on the first information, such as sampling point interval and sampling period. The network device may also receive a fifth piece of information sent by the terminal, wherein the fifth piece of information includes information of the merged sampling points (such as the sampling point interval and sampling period of the merged sampling points), thereby locating and / or sensing the terminal based on the fifth piece of information.

[0247] Optionally, the network device may also merge the sampling points according to the updated first information and send sixth information to the terminal, wherein the sixth information includes information of the merged sampling points.

[0248] For example, network devices can perform processing such as merging sampling points based on the updated first information to form sixth information. That is, the sixth information can include information about the merged sampling points. During sampling point merging, as the satellite moves, multiple lines (surfaces) can be formed between the satellite and the terminal's positioning and / or the sensing point and the satellite at different sampling points. The intersection of multiple lines (surfaces) can form a point, and multiple sampling points forming this point can be merged into one sampling point.

[0249] During the positioning and / or sensing process of network devices, if the area overlaps with the terrestrial network, the network devices can also combine and merge information from terrestrial cells (e.g., based on the location information corresponding to CGI (Common Gateway Interface) in the broadcast messages of terrestrial cells) to reduce the errors caused by data positioning and / or sensing by monorail satellites.

[0250] In this embodiment, the terminal sends first information to the network device. The first information includes one or more of the following: the location of a first sampling point, a first sampling period, the bandwidth used for the first sampling, the configuration of a reference signal for positioning and / or sensing, information on other terminals and / or other network devices participating in positioning and / or sensing the terminal, and resource information for positioning and / or sensing the terminal. This enables the network device to perform positioning and / or sensing based on the first information of the terminal, thereby improving the accuracy of positioning and / or sensing.
