Furthermore, multiple systems can be combined (e.g., LTE or LTE-A combined with 5G, 5G combined with 5G, 5G combined with 6G, etc.) for application.
[0139] In some embodiments, sensing technology refers to the integration of communication and sensing functions, enabling the communication system to simultaneously possess both communication and sensing capabilities. In this way, while transmitting information through a wireless channel, the communication device can also actively recognize and analyze the characteristics of the channel to perceive the physical features of the surrounding environment.
[0140] In some embodiments, the sensing technology includes a variety of different types. For example, the sensing technology includes at least one of the following: LiDAR-based sensing technology; millimeter-wave radar-based sensing technology; camera-based sensing technology, wherein the camera includes a visual camera and / or a time-of-flight (TOF) camera; sonar-based sensing technology; infrared-based sensing technology; cellular network-based sensing technology, wherein the cellular network can be a 4G (e.g., LTE), 5G (e.g., new radio, NR) or 6G cellular network; or sensing technology based on communication base station sensing or communication terminal sensing.
[0141] In some embodiments, depending on the type of sensing device, the information about the target object that the sensing device can acquire may include at least one of the following: coordinate information, such as coordinates relative to the wireless signal receiver, such as distance, horizontal angle, or vertical angle; speed information, such as the moving speed and direction of movement relative to the wireless signal receiver; signal strength; behavioral pattern information, such as motion information such as running, walking, approaching, falling, or swinging; weather information, such as rain or snow; and traffic information, such as congestion or accidents.
[0142] In some embodiments of ISAC technology, a wireless signal transmitter transmits radio waves, and a wireless signal receiver receives the radio waves. During the transmission of the radio waves, the transmission may be blocked by objects (hereinafter referred to as reflectors), resulting in wireless transmission effects such as reflection, diffraction, transmission, phase change, Doppler shift, and / or signal strength change. By receiving the radio waves and comparing the transmitted and received signals, or recording the historical changes in the received signal, the wireless signal receiver can obtain information about the reflectors (e.g., coordinate information, velocity information, signal strength, and / or behavior pattern information).
[0143] In some embodiments, the "signal transmitter" can be a terminal or a base station, and the "signal receiver" can be a terminal or a base station.
[0144] In some embodiments, the wireless signal transmitter and the wireless signal receiver may be from the same device or different devices. For example: Mode 1: Base station A transmits, base station B receives; Mode 2: Base station A transmits, base station A receives; Mode 3: Terminal A transmits, terminal B receives; Mode 4: Terminal A transmits, terminal A receives; Mode 5: Base station A transmits, terminal A receives; Mode 6: Terminal A transmits, base station A receives.
[0145] The above-mentioned mode can also be referred to as the perception mode.
[0146] In some embodiments, please refer to Table 1, which shows the advantages and disadvantages of different sensing methods.
[0147] Table 1
[0148] In some embodiments, when the wireless signal transmitter and receiver are co-located, this sensing method can be called mono-static sensing. When the wireless signal transmitter and receiver are not co-located, this sensing method can be called bi-static sensing.
[0149] In some embodiments, the location management function (LMF) can determine the positioning accuracy. The positioning method initiated by the LMF can adjust the positioning accuracy by modifying parameters. Based on terminal positioning, the LMF can obtain the positioning results reported by the terminal and evaluate the positioning accuracy. In sensing services, it is necessary to adjust the sensing range or sensing accuracy according to the service requirements.
[0150] In some embodiments, in a base station-based (e.g., vehicle-based) self-transmitting and self-receiving sensing mode, some parameters of the terminal's self-transmitting and self-receiving can be adjusted based on the vehicle speed. In scenarios with slow vehicle speeds, using low power can save power consumption and reduce interference to other terminals. In similar scenarios, using low-density signal transmission can save wireless resources.
[0151] In some embodiments, the sensing area is determined based on the transmit power (size) of the terminal (e.g., a vehicle), and the terminal's requirement for the sensing area ahead varies with vehicle speed. For example, at slow speeds, the required sensing area is smaller, and the requirements for sensing latency and accuracy are not as high. However, at fast speeds, the required sensing area is larger because the vehicle needs to sense situations further away, and the requirements for sensing latency and accuracy also increase. Therefore, some parameters of the terminal's sensing operations can be adjusted based on vehicle speed. In slow-speed scenarios, using low power can save power consumption and reduce interference to other terminals. In slow-speed scenarios, using low-density signal transmission can save wireless resources.
[0152] However, since the terminal's moving speed is not taken into account, the configuration parameter values for performing perception measurements cannot be adapted to the moving speed, resulting in the inaccurate and unreliable execution of perception measurements based on the configuration parameter values. This is a problem that needs to be considered.
[0153] Figure 2A is an interactive schematic diagram of a communication method according to an embodiment of the present disclosure. As shown in Figure 2A, the embodiment of the present disclosure relates to a communication method used in a communication system 100, the method including:
[0154] Step S2101: The terminal sends the second information to the access network device and / or the core network device.
[0155] In some embodiments, the access network device and / or core network device receive second information sent by the terminal.
[0156] In some embodiments, the second information may be report information, auxiliary information, configuration parameter auxiliary information, or indication information.
[0157] In some embodiments, the access network equipment may be a base station, and the core network equipment may be a first network element, such as SF-C.
[0158] In some embodiments, the second information is information associated with the speed at which the terminal moves.
[0159] In some embodiments, the information associated with the speed at which the terminal moves can be the speed of the terminal itself, or information determined based on the speed of the terminal, such as the QoS of perceived service requirements determined based on the speed of the terminal.
[0160] In some embodiments, before the terminal sends the second information to the access network device and / or core network device, the terminal may obtain the speed of its movement in real time (or periodically) and determine the second information based on the speed.
[0161] For example, the second information is the QoS of the perceived service requirements. During movement, the terminal acquires its real-time speed v (km / h) (v is greater than or equal to 0), determines the QoS of the perceived service requirements based on v, and then sends the second information to the access network equipment and / or core network equipment. It should be noted that in this disclosure, the speed v is greater than or equal to 0, and the unit can be either km / h or m / s; no limitation is made here.
[0162] In some embodiments, the QoS requirements for the sensing service differ depending on the speed at which the terminal moves. The parameters corresponding to QoS can be at least one of the following: 5G QoS Identifier (5QI); service priority; QoS flow information; and bit rate. However, it is not limited to these; it can also include the location accuracy of the sensing estimate, the speed accuracy of the sensing estimate, distance resolution, speed resolution, sensing service latency, missed detection rate, and / or false alarm rate, etc.
[0163] For example, when the terminal moves at a first speed, the terminal determines that the QoS required by the perceived service corresponds to a first service priority; when the terminal moves at a second speed, the terminal determines that the QoS required by the perceived service corresponds to a second service priority, wherein the first speed is greater than the second speed, and the first priority is higher than the second priority.
[0164] In some embodiments, after receiving the QoS requirement of the sensing service, the access network device and / or core network device can determine the terminal's demand information based on the QoS requirement of the sensing service and configure QoS parameters or parameters associated with the sensing service for the sensing service based on the demand information. Here, the configured QoS parameters can be the parameters corresponding to the QoS requirement of the sensing service.
[0165] In some embodiments, the terminal may periodically send second information to the access network device and / or the core network device, so that the access network device and / or the core network device can obtain the latest speed value obtained by the terminal.
[0166] In some embodiments, the second information includes at least one of the following: speed information, which indicates the speed at which the terminal moves; parameter information, which includes recommended configuration parameter values for the terminal, which are used to configure sensing measurements and are determined based on the speed at which the terminal moves; and QoS information, which indicates the QoS required by the sensing service and is determined based on the speed at which the terminal moves.
[0167] In some embodiments, speed information is used to indicate at least one of the following: speed level (also referred to as speed threshold), where different speed levels indicate different speed ranges; quantity, which is the number of times the serving cell of the terminal changes per unit time; and the speed at which the terminal moves (which may be the actual speed value of the terminal's movement). Here, the number of changes may also be the number of transformations or handovers, which is not limited here.
[0168] For example, the speed at which the terminal moves is within the range of a to b (where a and b are both numbers greater than or equal to 0, a is less than b, and the units of a and b can be kilometers per second or meters per second, without limitation here), and the speed level is the first speed level. It can be understood that the faster the terminal moves, the higher the corresponding speed level can be.
[0169] For example, if the number of times the terminal's serving cell changes is n times per unit time (n is an integer greater than or equal to 1), the terminal speed can be determined to be y kilometers per hour (y is greater than or equal to 0).
[0170] For example, if the terminal is currently moving at a speed of x km / h (x is greater than or equal to 0), then the speed information can be information indicating x km / h. For instance, the speed information may contain x km / h, or the speed information may contain an index indicating a speed of x km / h.
[0171] For example, if the terminal's current moving speed is x km / h (x is greater than or equal to 0), and the terminal determines the configuration parameter value for performing sensing measurements based on x km / h as t, then the parameter information can include this configuration parameter value t. Here, there is a mapping relationship between the speed and the configuration parameter value, and the terminal can determine the configuration parameter value for performing sensing measurements based on the detected speed and this mapping relationship. Here, the configuration parameter value can be a transmission power value for transmitting sensing signals and / or a transmission period value, etc.
[0172] For example, if the terminal is currently moving at a speed of x kilometers per hour (x is greater than or equal to 0), and the QoS required by the perceived service at this speed is the first QoS, then the QoS information can indicate the first QoS.
[0173] In some embodiments, QoS information may include at least one of the following parameters: 5QI; service priority; quality of service flow information; bit rate. However, it is not limited to this; QoS information may also include at least one of the following parameters: location accuracy of perception estimation; velocity accuracy of perception estimation; distance resolution; velocity resolution; perception service latency; missed detection rate; false alarm rate.
[0174] In some embodiments, QoS information can be used to determine the needs of a terminal. After receiving the QoS information, the access network device or network device can determine the terminal's needs based on the QoS information and configure the QoS parameters for the perceived service based on those needs. Here, the configured QoS parameters can be the parameters included in the QoS information, but are not limited to this; they can also be parameters reconfigured by the access network device or network device based on the terminal's needs.
[0175] In some embodiments, the second information is used to enable the access network device or the core network device to determine the first configuration parameter value, and the first configuration parameter value is used to configure sensing measurement.
[0176] In some embodiments, the first configuration parameter value may be at least one of the following: a transmission power value, the transmission power value being the power of the terminal transmitting the sensing and measurement signal; a transmission period value, the transmission period value being the period of the terminal transmitting the sensing and measurement signal; and a transmission density value, the transmission density value being the distribution density of the first resource in the time domain and / or frequency domain, the first resource being used to transmit the sensing and measurement signal.
[0177] In some embodiments, the first configuration parameter value may be the same as the parameter value included in the second information, such as the first configuration parameter value being the terminal-recommended configuration parameter value included in the second information.
[0178] In some embodiments, the sensing measurement signal is a measurement signal that the terminal needs to send to perform sensing measurements.
[0179] In some embodiments, the first configuration parameter value is one or more configuration parameter values activated by the network device from at least one configuration parameter value. For example, the network device pre-configures N (N is an integer greater than or equal to 1) configuration parameter values, and the first configuration parameter value can be a configuration parameter value activated from the N configuration parameter values, wherein the first configuration parameter value is a configuration parameter value that matches the second information.
[0180] In some embodiments, the terminal sends second information to the access network device and / or core network device based on a first event, wherein the first event is that the terminal's moving speed is greater than or equal to a speed threshold.
[0181] For example, when the terminal determines that the speed at which the terminal is moving is greater than or equal to a speed threshold, the terminal sends second information to the access network device and / or the core network device.
[0182] In some embodiments, the terminal sends second information to the access network device and / or core network device based on a first event, wherein the first event is that the number of times the terminal's serving cell changes within a unit time is greater than or equal to a number threshold.
[0183] For example, if the number of times the terminal's serving cell changes within a unit of time is greater than or equal to a threshold, the terminal sends second information to the access network equipment and / or the core network equipment.
[0184] In some embodiments, the terminal sends second information to the access network device and / or core network device based on a first event, wherein the first event is that the speed level corresponding to the terminal's speed is greater than or equal to the level threshold.
[0185] For example, when the speed level corresponding to the terminal's speed is greater than or equal to the level threshold, the terminal sends the second information to the access network device and / or the core network device.
[0186] In some embodiments, the speed threshold includes multiple thresholds set according to a gradient. For example, the multiple thresholds include a first speed threshold, a second speed threshold, and a third speed threshold (where the first speed threshold may be less than the second speed threshold, and the second speed threshold may be less than the third speed threshold). When the terminal determines that the speed at which the terminal is moving is greater than or equal to any of the multiple speed thresholds, it sends second information to the network device.
[0187] In some embodiments, the terminal sends second information to the access network device and / or core network device based on a first cycle.
[0188] In some embodiments, the speed threshold and / or the first cycle may be pre-configured by the network.
[0189] In some embodiments, the second information is further used to request the first information, wherein the first information is used to indicate a first configuration parameter value determined by the access network device and / or the core network device.
[0190] In some embodiments, the terminal sends RRC signaling to the access network device, and the RRC signaling includes second information.
[0191] In some embodiments, the terminal sends a MAC CE to the access network device, the MAC CE containing second information.
[0192] In some embodiments, the access network device receives the second information sent by the core network device, in which case step S2101 can be ignored.
[0193] In step S2102, the core network device sends the second information to the access network device.
[0194] In some embodiments, the access network device receives second information sent by the core network device.
[0195] In some embodiments, the second information may be report information, auxiliary information, configuration parameter auxiliary information, or indication information.
[0196] In some embodiments, the access network device may be a base station, the core network device may be a first network element, and the first network element may be SF-C.
[0197] In some embodiments, the second information is information associated with the speed at which the terminal moves.
[0198] In some embodiments, the information associated with the speed at which the terminal moves can be the speed itself, or information determined based on the speed.
[0199] In some embodiments, before the core network device sends the second information to the access network device, the core network device may obtain the speed of the terminal movement in real time (or periodically) and determine the second information based on the speed.
[0200] For example, the second information is the QoS of the perceived service requirements. When the terminal is moving, it will obtain the speed v km / h (v is greater than or equal to 0) of the terminal in real time and send v km / h to the core network equipment. The core network equipment determines the QoS of the perceived service requirements based on v km / h and then sends the second information to the access network equipment.
[0201] In some embodiments, the core network device may periodically send second information to the access network device, thereby enabling the access network device to obtain the latest mobile speed of the terminal.
[0202] In some embodiments, the second information includes at least one of the following: speed information, which indicates the speed at which the terminal moves; QoS information (also referred to as QoS requirement information), which indicates the QoS of perceived service requirements, and the QoS is determined based on the speed at which the terminal moves.
[0203] In some embodiments, QoS information can be used to determine a first QoS parameter, which can be mapped to a first DRB based on the mapping relationship between QoS and data radio bearer (DRB). The first DRB is associated with at least one logical channel, and the first QoS parameter can be used to adjust the configuration of the corresponding logical channel by adjusting the priority and / or bucket size.
[0204] In some embodiments, speed information is used to indicate at least one of the following: speed level, where different speed levels indicate different speed ranges; quantity, where the quantity is the number of times the terminal changes serving cells per unit time; and the magnitude of the terminal's movement speed (which may be the actual speed value of the terminal's movement).
[0205] For example, the speed at which the terminal moves is within the range of a to b (where a and b are both numbers greater than or equal to 0, a is less than b, and the units of a and b can be kilometers per hour or meters per second, without limitation here), and the speed level is the first speed level. It can be understood that the faster the terminal moves, the higher the corresponding speed level can be.
[0206] For example, if the number of times the terminal's serving cell changes is n (n is an integer greater than or equal to 1) per unit time, the terminal speed can be determined to be y kilometers per hour. It should be noted that the more frequently the terminal switches serving cells, the faster the terminal moves.
[0207] For example, if the terminal is currently moving at a speed of x kilometers per hour (x is greater than or equal to 0), then the speed information can be information used to indicate x. For instance, the speed information contains x, or the speed information contains an index that indicates a speed of x.
[0208] For example, if the terminal is currently moving at a speed of x kilometers per hour, and the QoS required by the perceived service at this speed is the first QoS, then the QoS information can indicate the first QoS.
[0209] For example, QoS information may include at least one of the following: location accuracy of perception estimation; velocity accuracy of perception estimation; distance resolution; velocity resolution; perception service latency; missed detection rate; false alarm rate.
[0210] In some embodiments, the second information is used to enable the network device to determine a first configuration parameter value, the first configuration parameter value being used to configure sensing measurements.
[0211] In some embodiments, the second information is speed information, which can be used to determine a first configuration parameter value, which may be at least one of a transmit power value, a transmit period value, and a transmit density value.
[0212] In some embodiments, the second information is parameter information, which can be used to determine a first configuration parameter value. The first configuration parameter value can be at least one of a transmit power value, a transmit period value, and a transmit density value.
[0213] In some embodiments, the second information is QoS information, which can be used to determine a first configuration parameter value. The first configuration parameter value can be at least one of a transmit power value, a transmit period value, and a transmit density value.
[0214] In some embodiments, there is a mapping relationship between the first configuration parameter value and the second information, and the mapping relationship is used by the network device to determine the first configuration parameter value based on the second information.
[0215] In some embodiments, the mapping relationship can be the relationship between speed information (or parameter information or QoS information, which will not be elaborated here) and transmit power value.
[0216] For example, the second information is used to indicate the speed level, and the mapping relationship can be a mapping relationship between the speed level and the first configuration parameter value, where the first configuration parameter value is the transmit power value.
[0217] For example, the mapping relationship could be: {Speed level 1, Transmission power P1}.
[0218] For example, the mapping relationship could be: {Speed Level 2, Transmission Power P2}. Here, P1 and P2 are transmission power values, both greater than 0. The units for P1 and P2 can be watts or kilowatts, without limitation.
[0219] In some embodiments, the mapping relationship can be the relationship between speed information (or parameter information or QoS information, which will not be elaborated here) and the transmission period value.
[0220] For example, the second information is used to indicate the speed level, and the mapping relationship can be a mapping relationship between the speed level and the first configuration parameter value, where the first configuration parameter value is the transmission cycle value.
[0221] For example, the mapping relationship could be: {speed level 1, launch period C1}.
[0222] For example, the mapping relationship could be: {Speed Level 2, Launch Period C2}. Here, C1 and C2 are period values, both greater than 0. The units for C1 and C2 can be seconds or milliseconds, without limitation.
[0223] In some embodiments, the mapping relationship can be the relationship between velocity information (or parameter information or QoS information, which will not be elaborated here) and transmission density value.
[0224] For example, the second information is used to indicate the speed level, and the mapping relationship can be a mapping relationship between the speed level and the first configuration parameter value. The first configuration parameter value can be a transmission density value determined based on the distribution of resources in the first resource set. The first resource set contains time-domain and / or frequency-domain resources of different densities for transmitting signals, and the transmission density values determined based on different first resource sets are different.
[0225] In some embodiments, the first resource set may be a set of launch resources.
[0226] For example, the mapping relationship could be: {Speed Level 1, First Resource Set A1}. Or, for example, the mapping relationship could be: {Speed Level 2, First Resource Set A2}.
[0227] In some embodiments, the first configuration parameter value may be at least one of the following: a transmit power value, which is the power of the terminal transmitting the sensing and measurement signal; a transmit period value, which is the period of the terminal transmitting the sensing and measurement signal; and a transmit density value, which is the distribution density of the first resource in the time domain and / or frequency domain, wherein the first resource is used to transmit the sensing and measurement signal. However, it is not limited to the above parameters.
[0228] In some embodiments, the sensing measurement signal is a measurement signal that needs to be sent to perform sensing measurements.
[0229] In some embodiments, the first configuration parameter value is one or more configuration parameter values activated by the network device from at least one configuration parameter value. For example, if the network device is pre-configured with N configuration parameter values, the first configuration parameter value may be one of the N configuration parameter values activated, and this first configuration parameter value is a configuration parameter value that matches the second information.
[0230] In some embodiments, the access network device receives the second information sent by the terminal. In this case, step S2102 can be ignored, as shown by the dashed arrow in FIG2a.
[0231] Step S2103: The network device determines the first configuration parameter value.
[0232] In some embodiments, if the terminal is sending the second information, the network device may be a core network device or an access network device.
[0233] In some embodiments, if the core network device sends the second information, the network device is an access network device.
[0234] In some embodiments, the network device determines a first configuration parameter value.
[0235] In some embodiments, there is a mapping relationship between the first configuration parameter value and the second information, and the network device can determine the first configuration parameter value based on the second information and the mapping relationship.
[0236] In some embodiments, based on the second information, the network device activates one or more configuration parameter values from at least one configuration parameter value (e.g., sensing measurement configuration). In this case, there is a mapping relationship between the second information and the activated configuration parameter value, and the network device determines the activated configuration parameter value as the first configuration parameter value based on the mapping relationship.
[0237] For example, the second information is speed information, which indicates the speed at which the terminal moves. The speed and the configuration parameter values have a mapping relationship as shown in Table 2.
[0238] Table 2
[0239] As shown in the table above, when the speed indicated by the second information is A, the network device activates parameter value 'a' among the three configuration parameter values, and the network device determines the first configuration parameter value to be parameter value 'a'. Of course, the same speed value D can correspond to multiple configuration parameter values, such as parameter values a1 and a2. The network device can activate both parameter values a1 and a2 simultaneously and determine them as the first configuration parameter values. After obtaining the first configuration parameter value, the terminal can choose either parameter value a1 or parameter value a2 to perform sensing measurement; this is not limited here.
[0240] It should be noted that network devices may also activate a configuration parameter value from an already configured configuration parameter value as the first configuration parameter value (activated sensing measurement configuration) without using the activation method, or they may regenerate a new configuration parameter value based on the second information (new configuration) and use the new configuration parameter value as the first configuration parameter value. There is no limitation here.
[0241] In some embodiments, if the second information is parameter information, which includes configuration parameter values recommended by the terminal, the network device can determine the first configuration parameter value as the configuration parameter value recommended by the terminal based on the second information. In this way, it can adapt to the terminal's recommendation and better meet the terminal's needs.
[0242] In some embodiments, if the second information is QoS information, which is used to indicate the QoS of the perceived service requirement, the network device can determine that the first configuration parameter value is the configuration parameter value corresponding to the QoS of the perceived service requirement, wherein there is a mapping relationship between QoS and configuration parameter value.
[0243] In step S2104, the network device sends the first information to the terminal.
[0244] In some embodiments, the terminal receives first information sent by the network device.
[0245] In some embodiments, if the terminal is sending the second information, the network device may be a core network device or an access network device.
[0246] In some embodiments, if the core network device sends the second information, the network device is an access network device.
[0247] In some embodiments, the first information is used to indicate a first configuration parameter value, which is the configuration parameter value determined in step S2103.
[0248] In some embodiments, the first information is used for the terminal to perform sensing measurements.
[0249] In some embodiments, the network device receives second information sent by the terminal, the second information being used to request first information. After receiving the second information, the network device sends the first information to the terminal. Thus, the network device can send the first information to the terminal based on the request, but is not limited thereto.
[0250] In some embodiments, the network device actively sends first information to the terminal, for example, the network device periodically sends first information to the terminal.
[0251] In some embodiments, after determining the value of the first configuration parameter, the network device sends the first information to the terminal.
[0252] In some embodiments, the first information includes an index that indicates a first configuration parameter value, and different indices indicate different first configuration parameter values.
[0253] For example, the first configuration parameter value can be a parameter A value and a parameter B value. When the first information contains a first index, the first index indicates the parameter A value. When the first information contains a second index, the second index indicates the parameter B value.
[0254] In some embodiments, the first information includes a first configuration parameter value.
[0255] In some embodiments, the first information is configuration parameter information, indication information, parameter configuration information, or configuration information.
[0256] In some embodiments, the network device sends RRC signaling to the terminal, the RRC signaling containing first information.
[0257] In some embodiments, the network device sends a MAC CE to the terminal, the MAC CE containing first information.
[0258] In some embodiments, the network device sends a DCI to the terminal, the DCI containing first information.
[0259] Step S2105: The terminal performs sensing measurements.
[0260] In some embodiments, the terminal performs sensing measurements based on first information.
[0261] In some embodiments, the terminal performs sensing measurements based on predefined or protocol-defined first information. In this case, step S2104 is an optional step and can be omitted.
[0262] In some embodiments, the terminal performs sensing measurements based on first information sent by the network device.
[0263] In some embodiments, the first information is used to indicate the value of the first configuration parameter.
[0264] In some embodiments, a network device sends first information to a terminal. The first information includes an index indicating a first configuration parameter value. Different indices indicate different first configuration parameter values. After receiving the first information, the terminal performs a sensing measurement based on the first configuration parameter value indicated by the index contained in the first information. For example, if the first information includes index 'a', and the first configuration parameter corresponding to index 'a' is parameter 'b', then the terminal performs a sensing measurement based on parameter 'b'.
[0265] In some embodiments, the network device sends first information to the terminal, the first information containing first configuration parameter values, and the terminal performs sensing measurements based on the first configuration parameter values contained in the first information after receiving the first information.
[0266] In some embodiments, a first piece of information is predefined, which indicates a predefined first configuration parameter, and the terminal performs sensing measurements based on the predefined first configuration parameter value.
[0267] In some embodiments, the protocol specifies first information, which indicates first configuration parameters specified in the protocol, and the terminal performs sensing measurements based on the first configuration parameters specified in the protocol.
[0268] In some embodiments, the terminal may update the first configuration parameter value based on the speed at which the terminal moves, and perform sensing measurements based on the updated first configuration parameter value.
[0269] In some embodiments, the terminal may determine the updated first configuration parameter based on the speed at which the terminal moves and a mapping relationship, and perform a sensing measurement based on the updated first configuration parameter; wherein, the mapping relationship is the mapping relationship between the speed at which the terminal moves and the configuration parameter value.
[0270] Since the speed of the terminal is constantly changing and may vary at different times, the configuration parameter values need to adapt to this change. Therefore, the first configuration parameter value corresponding to the current speed in the mapping relationship needs to be used to perform perception measurement. Thus, the first information needs to be updated to adapt to the changes in the speed of the terminal's movement.
[0271] In some embodiments, the first configuration parameter value is the transmission power value, and the terminal can transmit a sensing signal to the target object based on the transmission power value when performing sensing measurements.
[0272] In some embodiments, the first configuration parameter value is the transmission period value, and the terminal can transmit a sensing signal to the target object based on the transmission period value when performing sensing measurements.
[0273] In some embodiments, the first configuration parameter value is the emission density value, and the terminal can emit a sensing signal to the target object based on the emission density value when performing sensing measurements.
[0274] It should be noted that the scenario for performing sensing measurements in this disclosure can be one of the aforementioned ISAC sensing scenarios. The network side can pre-configure the ISAC sensing scenario, which is not limited here. The embodiments of this disclosure can be applied to one of the ISAC sensing scenarios, such as a self-transmitting and self-receiving sensing scenario.

[0284] Figure 2B is an interactive schematic diagram of a communication method according to an embodiment of the present disclosure. As shown in Figure 2B, the embodiment of the present disclosure relates to a communication method used in a communication system 100, the method including:
[0285] Step S2201: The network device sends the first information to the terminal.
[0286] In some embodiments, the terminal receives first information sent by the network device.
[0287] In some embodiments, the first information is used to indicate a first configuration parameter value, which can be understood as information pre-configured by the network for sensing measurements.
[0288] In some embodiments, the first information is used for the terminal to perform sensing measurements.
[0289] In some embodiments, the network device receives second information sent by the terminal, the second information being used to request first information; the network device then sends the first information to the terminal. The network device may send the first information to the terminal based on a request, but is not limited to this; it may also proactively send the first information to the terminal, for example, periodically.
[0290] In some embodiments, the network device receives second information sent by a terminal or core network device, the second information being used to determine the value of the first configuration parameter.
[0291] In some embodiments, after determining the value of the first configuration parameter based on the second information, the network device sends the first information to the terminal.
[0292] In some embodiments, the network device sends RRC signaling to the terminal, the RRC signaling containing first information.
[0293] In some embodiments, the network device sends a MAC CE to the terminal, the MAC CE containing first information.
[0294] In some embodiments, the network device sends a DCI to the terminal, the DCI containing first information.
[0295] It should be noted that the steps for determining the first configuration parameter value can be found in the exemplary description in the partial embodiment of Figure 2A, and will not be repeated here.
[0296] Step S2202: The terminal updates the first information.
[0297] In some embodiments, the first information may be sent by the network device, or it may be predefined or specified by a protocol, which is not limited here. If the first information is predefined or specified by a protocol, step S2201 can be ignored.
[0298] In some embodiments, the terminal updates the first configuration parameter value indicated by the first information.
[0299] In some embodiments, the terminal may update the first information based on the speed at which the terminal moves and the third information to obtain the fourth information; wherein the third information includes a configuration parameter value corresponding to the speed at which the terminal moves.
[0300] In some embodiments, the third information includes a mapping relationship between the speed at which the terminal moves and the configuration parameter values.
[0301] In some embodiments, the terminal can update the first information based on the speed of the terminal's movement and the mapping relationship to obtain the fourth information. It should be noted that since the speed of the terminal is constantly changing and may differ at different times, the configuration parameter values need to adapt to this change. Therefore, the first configuration parameter value corresponding to the current speed in the mapping relationship needs to be used to perform sensing measurements, and thus the first information needs to be updated to adapt to the changes in the speed of the terminal's movement.
[0302] For example, the first configuration parameter value is the transmission power value. The current speed of the terminal is v1, and the corresponding transmission power value is P1. When the terminal's speed is v2, the corresponding transmission power value is updated to P2. Then, the updated fourth information indicates that the first configuration parameter is the transmission power and that the corresponding value is P2. Here, v1 and v2 are greater than or equal to 0, and the unit can be kilometers per second or meters per second, without limitation; P1 and P2 are greater than 0, and the unit can be watts or kilowatts, without limitation.
[0303] For example, the first configuration parameter value is the transmission period value. The current terminal's movement speed is v1, and the corresponding transmission period value is C1. When the terminal's movement speed is v2, the corresponding transmission period value is updated to C2. The updated fourth information indicates that the first configuration parameter is the transmission period and that the corresponding value is C2. Here, v1 and v2 are greater than or equal to 0, and the unit can be kilometers per second or meters per second, without limitation. C1 and C2 are greater than 0, and the unit can be seconds or milliseconds, without limitation. For example, the first configuration parameter value is the transmission density value. The current terminal's movement speed is v1, and the corresponding transmission density value is M1. When the terminal's movement speed is v2, the corresponding transmission density value is updated to M2. The updated fourth information indicates that the first configuration parameter is the transmission density and that the corresponding value is M2. Here, v1 and v2 are greater than or equal to 0, and the unit can be kilometers per second or meters per second, without limitation. M1 and M2 are greater than 0, and the unit can be units per resource block, without limitation.
[0304] Step S2203: The terminal performs sensing measurements.
[0305] In some embodiments, the terminal performs sensing measurements based on the updated first information (corresponding to the fourth information).
[0306] For example, if the first configuration parameter value is the transmit power value, and the updated fourth information indicates a transmit power value of P1, then a sensing signal is transmitted based on P1 during the sensing measurement process. P1 is the transmit power value, which is greater than 0. The unit of P1 can be kilowatts or watts, and is not limited here.
[0307] For example, if the first configuration parameter value is the transmission period value, and the updated fourth information indicates a transmission period value of C1, then a sensing signal is transmitted based on C1 during the sensing measurement process. C1 is the transmission period value, and C1 is greater than 0. The unit of C1 can be seconds or milliseconds, which is not limited here.
[0308] For example, if the first configuration parameter value is the emission density value, and the emission density value indicated by the updated fourth information is M1, then a sensing signal is emitted based on M1 during the sensing measurement process. M1 is the emission density value, M1 is greater than 0, and the unit of M1 can be one unit of resource block, which is not limited here.
[0309] Step S2204: The terminal sends the fourth information to the network device.
[0310] In some embodiments, the network device receives fourth information sent by the terminal.
[0311] In some embodiments, the fourth information may be notification information.
[0312] In some embodiments, a fourth message is sent to the network device after the terminal updates the first message.
[0313] In some embodiments, after receiving the fourth information, the network device can use the updated fourth information to perform calculations in subsequent sensing and measurement calculations, making the calculation results more accurate and reliable.
[0314] The communication method involved in the embodiments of this disclosure may include at least one of steps S2201 to S2204.

[0315] In some embodiments, step S2201 may be optional, and one or more of these steps may be omitted or substituted in different embodiments.

[0349] In some embodiments, the steps and their optional implementations in other embodiments described before or after this embodiment, as well as other related parts in the specification, can be referred to, and will not be repeated here.
[0350] To better understand the embodiments of this disclosure, the technical solutions of this disclosure are further described below through some exemplary embodiments:
[0351] Example 1:
[0352] In some embodiments, the sensing area is determined based on the transmit power (or the magnitude of the transmit power) of the terminal (e.g., a vehicle), and the terminal's requirement for the sensing area ahead varies with vehicle speed. For example, at slow vehicle speeds, the required sensing area is smaller, and the requirements for sensing result acquisition latency and sensing accuracy are not as high. However, at fast vehicle speeds, the required sensing area is larger because the vehicle needs to sense situations at greater distances, and the requirements for sensing result acquisition latency and sensing accuracy also increase. Therefore, some parameters of the UE's self-transmitting and self-receiving can be adjusted based on vehicle speed. In slow vehicle speed scenarios, using low power can save power consumption and reduce interference to other terminals. In slow vehicle speed scenarios, using low-density signal transmission can save wireless resources.
[0353] In some embodiments, the transmit power (or transmit power magnitude) of the corresponding UE is mapped based on a speed threshold (corresponding to a speed level). For example: {speed threshold 1, transmit power P1 (corresponding transmit power value)}, and / or {speed threshold 2, transmit power P2}, etc.
[0354] In some embodiments, based on a speed threshold, the frequency or period (corresponding to the first period) of the UE's self-transmitted and self-received signal is mapped. For example: {speed threshold 1, signal transmission period P1 (corresponding to the transmission period value)}, and / or {speed threshold 2, signal transmission period P2}, etc.
[0355] In some embodiments, based on a speed threshold, the corresponding signal sets (corresponding signal combinations) of the UE's self-transmitted and self-received signals are different. A faster terminal movement speed allows the signal set to contain more signals, and vice versa. This is beneficial for UE energy saving. For example: {speed threshold 1, signal transmission set A1 (corresponding transmission density value)}, and / or {speed threshold 2, signal transmission set A2}, etc. Different signal transmission sets correspond to different densities of sensed signals.
[0356] Please refer to Figure 4, which provides a communication method, including one of the following schemes:
[0357] Option 1:
[0358] Step S4101: Send a velocity report (corresponding to velocity information).
[0359] In some embodiments, the speed report may be based on periodic or event-based transmission.
[0360] In some embodiments, speed reports are used to activate a sensing measurement configuration or to determine a new configuration.
[0361] In some embodiments, the UE can report based on its own speed, and the network side activates the UE's self-reporting and self-receiving resource configuration. The configuration parameters include the UE's self-reporting and self-receiving power, period, and set of transmitted signals. For example, the network side pre-configures multiple sets of sensing parameter configurations for the UE and configures the events triggered by UE reporting, such as reporting based on a speed threshold, thereby triggering the base station to activate a certain sensing parameter configuration. Event reporting should be triggered immediately if the speed is greater than a certain threshold; if it is lower than a certain threshold, reporting should be delayed by a time T.
[0362] Step S4102: Receive the activated perception measurement configuration or new configuration (corresponding to the first information).
[0363] Option 2:
[0364] Step S4103: Send sensing measurement configuration (corresponding parameter information).
[0365] In some embodiments, the sensing measurement parameters are used to activate the sensing measurement configuration or determine a new configuration.
[0366] In some embodiments, the UE requests the desired perception measurement configuration from the network side based on its own speed.
[0367] In some embodiments, the network side activates pre-configured parameters to update the configuration used by perception.
[0368] Step S4104: Receive the activated perception measurement configuration or new configuration (corresponding to the first information).
[0369] Option 3:
[0370] Step S4105: Send QoS requirement based on UE velocity (corresponding QoS information).
[0371] In some embodiments, QoS comes from SF-C's UE speed or update QoS requirements.
[0372] In some embodiments, the UE reports QoS requirements based on its own speed, such as the location accuracy of the perception estimate, the speed accuracy of the perception estimate, the distance resolution, the speed resolution, the perceived service latency, the missed detection rate, and the false alarm rate.
[0373] In some embodiments, the network side activates pre-configured parameters to update the configuration used by sensing.
[0374] Step S4106: Receive the activated perception measurement configuration or new configuration (corresponding to the first information).
[0375] Option 4:
[0376] Step S4107: Obtain UE speed (corresponding speed information) or update QoS requirements (corresponding QoS information) from SF-C.
[0377] In some embodiments, the UE speed or update QoS requirement from SF-C is the UE speed or update QoS requirement from SF-C.
[0378] In some embodiments, the base station obtains the UE's speed information or updated QoS requirements from the SF-C.
[0379] In some embodiments, the network side activates pre-configured parameters to update the configuration used by sensing.
[0380] Step S4108: Receive the activated perception measurement configuration or new configuration (corresponding to the first information).
[0381] In some embodiments, for schemes 1 to 4 above, network-side activation parameters can be sent via RRC signaling, MAC CE, or DCI.
[0382] In some embodiments, for schemes 1 to 4 above, network-side activation parameters can be sent to the UE via SF-C signaling.
[0383] The network side here can be a base station or SF-C.
[0384] In some embodiments, for the UE's self-sensing process in vehicle scenarios, the latency requirements for sensing results are relatively high. Therefore, the further down the processing node for sensing results is, the better for latency. Thus, the sensing data processing node can be located at the UE, or at the base station if the UE is unable to process the sensing data.
[0385] In some embodiments, speed information or speed auxiliary information may be: speed level (each speed level corresponds to a speed range) or a measurement characterizing speed (e.g., the number of cell changes within a specified time), or an absolute speed value.
[0386] In some embodiments, the above-mentioned speed-based configuration adjustment is merely a use case, and configuration changes triggered by other factors are not excluded.
[0387] In some embodiments, different UE speeds may correspond to different parameter configurations, and the parameter configurations may include one or a combination of several of the following: power of the transmitted signal, period of the transmitted signal, density of the transmitted signal, and set of transmitted signals.
[0388] In some embodiments, the UE configures multiple sets of parameters for the terminal based on network side settings, as well as a sensing mode, such as self-transmission and self-reception. Each set of parameters may explicitly or implicitly include an index. Each set of parameters may include one or a combination of several of the following: transmitted signal power, transmitted signal period, transmitted signal density, and a set of transmitted signals. The network side indicates the latest parameters to be used based on the index.
[0389] In some embodiments, the UE decides to change the configuration based on the speed range and corresponding configuration configured by the network side, and notifies the network side of the latest selected configuration (corresponding to the fourth information).
[0390] In some embodiments, the UE decides to change the configuration itself based on the speed range and corresponding configuration configured by the network side, without notifying the network side of the latest selected configuration.
[0391] In some embodiments, based on UE speed information, UE preferences, or updated QoS requirements, the network side may change the values of sensing configuration parameters, including the power of the transmitted signal, the period of the transmitted signal, and the density of the transmitted signal.

Furthermore, it can also be a hardware circuit designed for artificial intelligence, which can be understood as an ASIC, such as a neural network processing unit (NPU), tensor processing unit (TPU), deep learning processing unit (DPU), etc.
