Wireless communication method, terminal device, and network device

Abstract

Provided are a wireless communication method, a terminal device, and a network device. The method comprises: a terminal device sends a first sensing signal to a network device, wherein a sensing result obtained on the basis of the first sensing signal is used for implementing cell reselection of the terminal device. The relevant technology does not take into account the impact of the sensing result between the terminal device and the network device on cell reselection. Therefore, the terminal device may select a cell with respect to which the terminal device has a relatively high movement speed, or a cell where a line-of-sight path is obstructed, or a cell for which distance information provided by sensing is inconsistent with map information, or the like. In this case, the terminal device may soon face the need to perform reselection again, which adversely affects the power consumption, user experience, and other aspects of the terminal device. However, in the present application, cell reselection can be implemented on the basis of a sensing result, so that the described problem can be avoided, thereby reducing energy consumption of the terminal device and improving user experience.

In such cases, the terminal device may face the need for rapid reselection, which negatively impacts power consumption and user experience. This application, however, enables cell reselection based on perception results, thereby avoiding the aforementioned problems, saving terminal device power consumption, and improving user experience.

[0036] It should be understood that all or part of the functions of the communication device in this application can also be implemented by software functions running on hardware, or by virtualization functions instantiated on a platform (e.g., a cloud platform).

[0037] Perception

[0038] Wireless sensing is an emerging technology that utilizes ubiquitous wireless signals to perceive our surroundings. It enables a wide range of applications, such as gesture recognition for human-computer interaction, vital sign monitoring in healthcare, and intrusion detection for security management.

[0039] Typical radio frequency (RF) signals (300kHz-300GHz) are essentially electromagnetic (EM) waves. When propagating in the physical world, these waves undergo various physical phenomena such as reflection, diffraction, and scattering. The multipath signals eventually superimpose and are received by the receiver. Therefore, the received superimposed signal carries physical information about the signal propagation space. In particular, from the received signal, the transmitter can analyze and determine the distance and relative speed of the sensed objects.

[0040] Consider a scenario where the locations of both the transmitter (Tx) and the sensing objective are known to the transmitter. The transmitter sends a reference signal towards the objective and then measures the signal reflected back from the objective. Using this location knowledge and the sensing result, the transmitter can determine whether a line-of-sight (LOS) path exists between the transmitter and the objective by comparing the distance derived from the location knowledge with the distance derived from the sensing result. If the difference is below a certain threshold, the transmitter considers a LOS path to exist between the transmitter and the objective.

[0041] Community re-election

[0042] For ease of understanding, the cell reselection process is explained below using a 5G system as an example. It is understood that this cell reselection process is merely an example and is not intended to limit this application; that is, this application can also be applied to other communication systems.

[0043] The UE performs cell reselection procedure in the RRC_IDLE state.

[0044] Different trigger conditions should be followed for intra-frequency measurement and inter-frequency measurement.

[0045] Intra-frequency / inter-frequency reselection with equal priority is based on the cell ranking.

[0046] Inter-frequency cell reselection takes into account the priority of the frequency and the corresponding cell: when the target cell signal level is good enough, reselection should be performed to a cell with a higher priority; when the serving cell signal level is low enough and the target cell signal level is good enough, reselection should be performed to a cell with a lower priority.

[0047] For NTN satellite cells, if the distance between the UE and the serving gNB is long enough, the UE still needs to perform cell reselection-related measurements even if the signal level is good enough.

[0048] The triggering conditions for same-frequency measurement and different-frequency measurement in 5G systems are explained below.

[0049] Intra-frequency measurement triggering condition

[0050] If the condition Srxlev > SIntraSearchP and Squal > SIntraSearchQ is not met, the UE performs intra-frequency measurement. If the condition is met, the UE further checks whether it is within the specific range of the serving gNB, if distanceThresh and referenceLocation are broadcast in SIB19, and if the UE supports location-based measurement initiation and has obtained its location information.

[0051] Inter-frequency measurement triggering condition

[0052] For frequencies with higher frequency reselection priority, the UE must always perform a measurement.

[0053] For frequencies with the same or lower reselection priority, the UE does not need to perform the measurement if the serving cell satisfies Srxlev > SnonIntraSearchP and Squal > SnonIntraSearchQ.

[0054] If the condition is met, but the UE is outside the specific range of the serving gNB, the UE still needs to perform the measurement if distanceThresh and referenceLocation are broadcast in SIB19.

[0055] The cell reselection criteria under different circumstances are explained below.

[0056] Intra-frequency and equal-priority inter-frequency cell reselection criteria

[0057] The calculation methods for the neighborhood ranking criteria Rs and Rn are as follows: R s =Q meas,s +Q hyst -Qoffset temp R n =Q meas,n -Qoffset–Qoffset temp

[0058] Cell reselection rule:

[0059] If rangeToBestCell is not configured, the UE should perform cell reselection to the highest-ranked cell.

[0060] If rangeToBestCell is configured, the UE shall perform cell reselection to the cell with the highest number of beams above the threshold among the cells whose R value is the top rangeToBestCell.

[0061] Inter-frequency and inter-RAT cell reselection criteria

[0062] For higher priority NR frequencies: if the target cell satisfies Squal > ThreshX, HighQ Or Srxlev>ThreshX, HighP, the UE reselects to the cell if the target cell fulfils Squal>ThreshX, HighQ or Srxlev>ThreshX, HighP ).

[0063] For NR frequencies of equal priority: based on ranking for intra-frequency cell reselection.

[0064] For NR frequencies of lower priority: if the serving cell fulfils STh, the UE reselects to the cell.

[0065] The inventor of the present application found that the cell reselection process in the related art can be further improved.

[0066] FIG. 2 is a schematic flowchart of a wireless communication method provided by an embodiment of the present application. The method shown in FIG. 2 may be performed by a terminal device and a network device.

[0067] The network device may include a first network device and / or a second network device. The first network device may be the network device corresponding to the serving cell of the terminal device. The second network device may be the network device corresponding to the neighboring cell of the serving cell. The first network device and the second network device may be the same network device or different network devices.

[0068] The method shown in FIG. 2 includes step S210.

[0069] In step S210, the terminal device sends a first sensing signal to the network device. The first sensing signal can implement the sensing process described above. For example, the first sensing signal may include one or more reference signals for sensing. The reference signals for sensing may be configured by the network device. Illustratively, the reference signal may include an SRS signal.

[0070] The sensing result obtained based on the first sensing signal can be used to implement cell reselection of the terminal device. That is, in the present application, the sensing result needs to be considered in the cell reselection process.

[0071] As described above, the network device may include a first network device and / or a second network device. The first sensing signal may include a second sensing signal and / or a third sensing signal. The second sensing signal may be sent to the first network device. The third sensing signal may be sent to the second network device. Based on this, the terminal device may send the first sensing signal to the serving cell and / or neighboring cells to obtain the sensing results for the serving cell and / or neighboring cells. Based on the sensing results for the serving cell and / or neighboring cells, a cell reselection process can be implemented.

[0072] In some embodiments, the sensing result may include one or more of the following: a first measured distance, a second measured distance, a first relative motion speed, a second relative motion speed, etc. The first measured distance is the distance between a first network device and a terminal device obtained based on a first sensing signal. The second measured distance is the distance between a second network device and a terminal device obtained based on the first sensing signal. The first relative motion speed may be the relative motion speed between the terminal device and the first network device obtained based on the first sensing signal (e.g., a second sensing signal included in the first sensing signal). The second relative motion speed may be the relative motion speed between the terminal device and the second network device obtained based on the first sensing signal (e.g., a third sensing signal included in the first sensing signal).

[0073] Without considering the sensing results between the terminal device and network device, the terminal device might select a cell with a relatively high moving speed relative to the terminal device, a cell with obstructions in its direct path, or a cell where the distance information provided by the sensing does not match the map information. In such cases, the terminal device may face the need to reselect cells frequently, which negatively impacts power consumption and user experience. This application, however, enables cell reselection based on sensing results, thereby avoiding the aforementioned problems, saving terminal device power consumption, and improving user experience.

[0074] In some embodiments, the first sensing signal can be transmitted on unlicensed spectrum and / or a resource pool. The resource pool may include transmission resources for the wireless sensing signal. Optionally, the resource pool may be configured by a network device. For example, the network device may broadcast a first message, which may include configuration information of the resource pool.

[0075] It should be noted that this application does not limit the method of determining the sensing result. For example, the sensing result can be obtained by monitoring the first sensing signal of backscattering. Exemplarily, the terminal device can monitor the first sensing signal of backscattering to determine the sensing result.

[0076] In some embodiments, the terminal device can receive location information sent by the network device. This location information can be used to indicate the actual location of the network device. In other words, the location information can be used to indicate the ground-truth location information of the network device.

[0077] In one implementation, when the network device is a fixed device, the actual location of the network device is its location. For example, location information may include coordinate information (such as latitude and longitude) that sets the location of the network device.

[0078] As one implementation method, when the network device is a mobile network device, its actual location can be determined or indicated by one or more of the following: the network device's movement path, movement speed, etc. For example, when the network device includes a satellite, the location information can include one or more of the following: the satellite's ephemeris information, the satellite's movement speed, the satellite's orbit, etc.

[0079] In some embodiments, network devices may broadcast location information.

[0080] The following example is illustrated with reference to Figure 3. In Figure 3, the first sensing signal includes the SRS signal. The method shown in Figure 3 includes steps S310 to S330.

[0081] In step S310, the network device sends its real location information to the terminal device.

[0082] Optionally, step S310 can be sent via broadcast.

[0083] Optionally, the method shown in FIG3 may include step S315. In step S315, the network device sends information about the SRS configuration resource pool for wireless sensing purposes. Exemplarily, step S315 may be sent via broadcast.

[0084] In step S320, the terminal device sends an SRS signal to the network device.

[0085] As one implementation method, the terminal device can send SRS signals from the resources in the SRS resource pool configured in the network device.

[0086] As one implementation method, the terminal device can transmit SRS signals on unlicensed spectrum.

[0087] Step S330: The terminal device monitors the back-scattered SRS signal.

[0088] The sensing results can be obtained based on the monitored backscattered SRS signals. The terminal equipment can analyze the sensing results to enable cell reselection.

[0089] In some embodiments, the sensing results may include one or more of the following: the distance between the terminal device and the network device; the relative speed between the terminal device and the network device. In other words, one or more of the following sensing results can be obtained through the first sensing signal to achieve cell reselection: the distance between the terminal device and the network device, and the relative speed between the terminal device and the network device.

[0090] It should be noted that "implementing cell reselection" in this application may include some or all of the steps in the cell reselection process. That is, any step in the cell reselection process can be implemented based on the sensing results. The following explanation uses the triggering of the measurement process and the execution of the cell reselection process as examples.

[0091] In some embodiments, the terminal device may perform measurements for co-frequency and / or inter-frequency devices when a first condition is met. The first condition may be related to a sensing result. The sensing result may be a sensing result corresponding to the serving cell. That is, the terminal device can determine whether to perform measurements for co-frequency and / or inter-frequency devices based on the condition related to the sensing result corresponding to the serving cell.

[0092] In some embodiments, measurements for different frequencies with the same frequency, same priority, or lower priority can be performed based on a first condition. For example, if the first condition is met, the terminal device can perform measurements for different frequencies with the same frequency, same priority, or lower priority. Measurements for higher priority frequencies are not subject to the first condition. In other words, the terminal device always performs measurements for higher priority frequencies.

[0093] It should be noted that the priority in this application can be obtained by comparing it with the priority corresponding to the serving cell (hereinafter referred to as the first priority). The first priority can, for example, be the priority of the frequency in which the serving cell is located. Taking the determination of the priority of the first frequency as an example, if the priority of the first frequency is higher than the first priority, then the first frequency is a high-priority frequency. Similarly, if the priority of the first frequency is equal to the first priority, then the first frequency is a frequency of the same priority. And if the priority of the first frequency is lower than the first priority, then the first frequency is a low-priority frequency.

[0094] The first condition is illustrated below. The first condition may include: a significant difference between the first measured distance and the first actual distance (e.g., greater than or equal to a first distance threshold). The first actual distance can be obtained based on the location of the terminal device and the actual location of the first network device.

[0095] Differences can be represented by similarity and / or dissimilarity. Higher similarity indicates greater similarity between the two values ​​and a smaller difference. Lower similarity indicates greater dissimilarity between the two values ​​and a larger difference. Similarly, lower dissimilarity indicates greater similarity between the two values ​​and a smaller difference. Conversely, higher dissimilarity indicates greater dissimilarity between the two values ​​and a larger difference.

[0096] As one implementation method, the first condition may include: the similarity between the first measured distance and the first actual distance is less than or equal to a first threshold, and / or, the dissimilarity between the first measured distance and the first actual distance is greater than or equal to a second threshold. It is understood that if the similarity is small or the dissimilarity is large, the gap between the perceived distance and the actual distance is greater, meaning the perception is less accurate (e.g., lacking a direct path). This indicates that the accuracy of the perception results between the terminal device and the serving cell is insufficient, resulting in poor service performance from the serving cell to the terminal device. Triggering measurements for other cells allows for rapid reselection to other cells, thereby ensuring a better user experience.

[0097] For example, the difference between the first measured distance and the first actual distance is the first difference, and the similarity between the first measured distance and the first actual distance includes one or more of the following: the ratio of the first difference to the first actual distance; the reciprocal of the first difference.

[0098] For example, the dissimilarity between the first measured distance and the first actual distance includes a first difference. The difference between the first measured distance and the first actual distance is the first difference.

[0099] It should be noted that, in this application, the difference between A and B can include: AB, BA, or |AB|, etc.

[0100] In some embodiments, one or more of the first threshold and the second threshold are configured, pre-configured, or predefined by the network device. For example, the network device may send configuration information to the terminal device. This configuration information can be used to configure the threshold for the terminal device to perform cell reselection based on sensing results. For instance, the configuration information can be used to configure one or more of the first threshold and the second threshold.

[0101] It should be noted that the location of a terminal device can be obtained through non-sensory technologies. For example, the location can be obtained through positioning technologies. Positioning technologies include one or more of the following: satellite-based positioning technology, cellular network-based positioning technology, WiFi-based positioning technology, Bluetooth-based positioning technology, and inertial navigation system-based positioning technology.

[0102] In some embodiments, the first condition may be related to a first relative motion speed, that is, the first condition for determining the trigger measurement may be related to the relative motion speed between the terminal device and the network device corresponding to the serving cell.

[0103] As one implementation method, the first condition may include: the first relative motion speed is greater than or equal to the third threshold. It is understood that if the first relative motion speed is large, meaning the relative motion speed between the terminal device and the network equipment corresponding to the serving cell is large, the service quality provided by the serving cell to the terminal device is poor. Triggering measurements for other cells can quickly reselect to other cells, thereby ensuring user experience.

[0104] In some embodiments, the third threshold is configured, pre-configured, or predefined by the network device. For example, the configuration information described above can be used to configure the third threshold.

[0105] For example, the triggering conditions for same-frequency / same-priority different-frequency / low-priority different-frequency measurements may include: the condition Srxlev>SIntraSearchP and Squal>SIntraSearchQ is not met, or the similarity between the first measured distance and the first actual distance is less than or equal to a first threshold, or the dissimilarity between the first measured distance and the first actual distance is greater than or equal to a second threshold.

[0106] To facilitate understanding, examples from Example 1 will be provided below.

[0107] Example 1

[0108] Figure 4 is a schematic flowchart of a communication process provided in Embodiment 1 of this application. The method shown in Figure 4 can be executed by a terminal device and a network device.

[0109] The method shown in Figure 4 may include steps S410 to S430.

[0110] Step S410 may include step S411 and / or step S412.

[0111] In step S411, the network device sends proprietary signaling. The proprietary signaling is used to configure one or more of the following: a first threshold, a second threshold, and a third threshold.

[0112] In step S412, the network device broadcasts a message. The broadcast message is used to configure one or more of the following: a first threshold, a second threshold, and a third threshold.

[0113] In step S420, the terminal device measures one or all of the configured reference signals. The first sensing signal may include one or more configured reference signals. Based on step S420, a sensing result can be obtained.

[0114] In step S430, the terminal device determines whether to trigger same-frequency / different-frequency measurement based on the sensing results.

[0115] In some embodiments, if a second condition is met, the terminal device performs cell reselection to a neighboring cell (i.e., the target cell) corresponding to the second network device. The second condition is related to the perception results. The perception results may include perception results for the first network device and / or perception results for the second network device. In other words, whether to perform cell reselection to a neighboring cell corresponding to the second network device can be determined based on the second condition related to the perception results for the first network device and / or the perception results for the second network device.

[0116] As one implementation method, the second condition may be related to one or more of the following: first measured distance, first actual distance, second measured distance, second actual distance, first relative velocity, second relative velocity, first priority, and second priority. For detailed explanations of the first measured distance, first actual distance, and first relative velocity, please refer to the above text; they will not be repeated here.

[0117] The second measured distance is the distance between the second network device and the terminal device obtained based on the first sensing channel measurement. In other words, the second measured distance can be considered part of the sensing result.

[0118] The second actual distance is obtained based on the location of the terminal device and the actual location of the second network device. In other words, the second actual distance can be equated to the actual distance between the terminal device and the second network device.

[0119] The second relative motion speed is the relative motion speed between the second network device and the terminal device. The second relative motion speed is obtained based on the first sensing signal; that is, the second relative motion speed can be attributed to the sensing result.

[0120] The first priority is the frequency of the serving cell (the cell corresponding to the first network device). The second priority is the frequency of the neighboring cell (the cell corresponding to the second network device).

[0121] The following example illustrates the second condition when the second priority is higher than the first priority, i.e., the condition for performing cell reselection to a higher-priority inter-frequency neighboring cell. In this case, the second condition may include one or more of the following: the similarity between the second measured distance and the second actual distance is greater than or equal to a fourth threshold; the dissimilarity between the second measured distance and the second actual distance is less than or equal to a fifth threshold; the second relative motion speed is less than or equal to a sixth threshold.

[0122] For example, the difference between the second measured distance and the second actual distance is a second difference value. The similarity between the second measured distance and the second actual distance can include one or more of the following: the ratio of the second difference value to the second actual distance; the reciprocal of the second difference value. The dissimilarity between the second measured distance and the second actual distance can include the second difference value.

[0123] In some embodiments, one or more of the fourth, fifth, and sixth thresholds are configured, pre-configured, or predefined by the network device. For example, the configuration information described above can be used to configure one or more of the fourth, fifth, and sixth thresholds.

[0124] For example, if the cell satisfies Squal > ThreshX, HighQ Or Srxlev>ThreshX, HighP Furthermore, the target cell satisfies one or more of the following: the similarity between the second measured distance and the second actual distance is greater than or equal to a fourth threshold; the dissimilarity between the second measured distance and the second actual distance is less than or equal to a fifth threshold; the second relative motion speed is less than or equal to a sixth threshold, and the terminal device can reselect to the target cell. Among these, Squal, ThreshX, HighQ Srxlev>ThreshX, HighP You can refer to the definitions in the relevant technologies.

[0125] The following example illustrates the second condition when the second priority equals the first priority or is on the same frequency, i.e., the condition for performing cell reselection to a neighboring cell on a different frequency with the same or same priority. In this case, the second condition can be related to the serving cell's Rs and the neighboring cell's Rn. Rs can be calculated based on one or more of the first actual distance, the first measured distance, and the first relative motion speed. Rn can be calculated based on one or more of the second actual distance, the second measured distance, and the second relative motion speed. Where R represents the cell ranking. Rs represents the serving cell ranking. Rn represents the neighboring cell ranking. For example, if rangeToBestCell is not configured, the terminal device should perform cell reselection to the cell with the highest ranking. As another example, if rangeToBestCell is configured, the terminal device should perform cell reselection to the cell with the most beams whose R value is within the rangeToBestCell range and above the threshold.

[0126] For example, Rs can be calculated using a first score. The first score can be a score relating the wireless sensing distance between the terminal device and the serving cell. The first score can be obtained through the similarity or dissimilarity between the first actual distance and the first measured distance. The greater the difference between the first actual distance and the first measured distance, the smaller the first score. For example, the first score can be equal to the similarity between the first actual distance and the first measured distance. Alternatively, the first score can be equal to the reciprocal of the dissimilarity between the first actual distance and the first measured distance.

[0127] For example, Rn can be calculated using a second score. The second score can be a score relating the terminal device to the wireless sensing distance of neighboring cells. The second score can be obtained through the similarity or dissimilarity between the second actual distance and the second measured distance. The greater the difference between the second actual distance and the second measured distance, the smaller the second score. For example, the second score can be equal to the similarity between the second actual distance and the second measured distance. Alternatively, the second score can be equal to the reciprocal of the dissimilarity between the second actual distance and the second measured distance.

[0128] For example, Rs can be calculated using a third fraction. The third fraction is derived from the first relative velocity. The greater the first relative velocity, the lower the third fraction. For instance, the third fraction can be equal to the reciprocal of the first relative velocity.

[0129] For example, Rn can be calculated using a fourth fraction. The fourth fraction is derived from the second relative velocity. The greater the second relative velocity, the lower the fourth fraction. For instance, the fourth fraction can be equal to the reciprocal of the second relative velocity.

[0130] As one implementation method, Rs = first fraction + second fraction + Q meas,s +Qhyst –Qoffset temp Rn = Third fraction + Fourth fraction + Q meas,n-Qoffset –Q offsettemp .

[0131] The following example illustrates the second condition when the second priority is less than the first priority, namely, the condition for performing cell reselection to a neighboring cell of the same priority but on a different frequency.

[0132] When the second priority is less than the first priority, the second condition includes one or more of the following: the similarity between the second measured distance and the second actual distance is greater than or equal to the seventh threshold; the dissimilarity between the second measured distance and the second actual distance is less than or equal to the eighth threshold; the second relative motion speed is less than or equal to the ninth threshold; the similarity between the first measured distance and the first actual distance is less than or equal to the tenth threshold; the dissimilarity between the first measured distance and the first actual distance is greater than or equal to the eleventh threshold; and the first relative motion speed is greater than or equal to the twelfth threshold.

[0133] The similarity and dissimilarity between the first measured distance and the first actual distance have been described above and will not be repeated here. The following examples illustrate the similarity and dissimilarity between the second measured distance and the second actual distance.

[0134] For example, the difference between the second measured distance and the second actual distance is a second difference. The similarity between the second measured distance and the second actual distance includes one or more of the following: the ratio of the second difference to the second actual distance, and the reciprocal of the second difference. The dissimilarity between the second measured distance and the second actual distance includes the second difference.

[0135] In some embodiments, one or more of the seventh, eighth, ninth, tenth, eleventh, and twelfth thresholds are configured, pre-configured, or predefined by the network device. For example, the configuration information described above can be used to configure one or more of the seventh, eighth, ninth, tenth, eleventh, and twelfth thresholds.

[0136] For example, for a frequency with a lower priority, if the serving cell satisfies STh, and one or more of the following conditions are met, the terminal device will reselect to the cell: the similarity between the second measured distance and the second actual distance is greater than or equal to a seventh threshold; the dissimilarity between the second measured distance and the second actual distance is less than or equal to an eighth threshold; a second relative movement speed is less than or equal to a ninth threshold; the similarity between a first measured distance and a first actual distance is less than or equal to a tenth threshold; the dissimilarity between the first measured distance and the first actual distance is greater than or equal to an eleventh threshold; and a first relative movement speed is greater than or equal to a twelfth threshold.
