In some embodiments, access network devices, core network devices, or network devices can be replaced by terminals. For example, embodiments of this disclosure can also be applied to structures where communication between access network devices, core network devices, or network devices and terminals is replaced by communication between multiple terminals (e.g., device-to-device (D2D), vehicle-to-everything (V2X), etc.). In this case, the structure can also be configured such that the terminal has all or part of the functions of the access network device. Furthermore, terms such as "uplink" and "downlink" can be replaced with terms corresponding to communication between terminals (e.g., "sidelink"). For example, uplink channel, downlink channel, etc., can be replaced with sidelink channel, and uplink link, downlink, etc., can be replaced with sidelink link.

In some embodiments, the terminal may be replaced by an access network device, a core network device, or a network device. In this case, the access network device, core network device, or network device may also be configured to have all or some of the functions of the terminal.

In some embodiments, the acquisition of data, information, etc., may comply with the laws and regulations of the country where the location is situated.

In some embodiments, data, information, etc., may be obtained with the user's consent.

Furthermore, each element, each row, or each column in the table of this disclosure can be implemented as an independent embodiment, and any combination of any element, any row, or any column can also be implemented as an independent embodiment.

In NR, especially when the communication frequency band is in frequency range 2, high-frequency channels attenuate quickly, so beam-based transmission and reception are required to ensure coverage.

During beam management, network devices configure a set of reference signal resources for beam measurement. The terminal measures the reference signal resources within this set and reports the IDs of some of the stronger reference signal resources, along with their corresponding Layer 1 reference signal received power (L1-RSRP) and/or Layer 1 signal-to-interference-plus-noise ratio (L1-SINR), to the network device.

In related technologies, it is assumed that the network device's set of reference signal resources includes X reference signal resources, each corresponding to a different transmit beam of the network device. For each reference signal resource, the terminal needs to use all receive beams to measure the reference signal, obtain the beam measurement quality corresponding to each receive beam, and determine one or more of the best beam measurement qualities. Therefore, the number of beam pairs that the terminal needs to measure is M*N. Here, M represents the number of transmit beams of the network device, and N is the number of receive beams of the terminal.

However, for most users, their commuting routes on weekdays are relatively fixed, meaning the beams used along the way are also relatively fixed. Performing beam measurements daily would increase the complexity of the terminal's measurements and boost power consumption. Even for different users, beam reporting can be based on historical beam reports from other users at a specific location, eliminating the need for repeated measurements.

This disclosure provides a communication method in which a terminal acquires a beam map. The beam map includes a correspondence between first information used to determine the terminal's location and beam reports. This allows the terminal to obtain beam reports corresponding to its location information based on the beam map, reducing the number of beam measurements performed by the terminal and thus lowering its power consumption.

Figure 2 is an interactive schematic diagram of a communication method according to an embodiment of the present disclosure. As shown in Figure 2, the embodiments of the present disclosure relate to a communication method, which includes:

Step S2101: The terminal acquires the beam map.

In some embodiments, the beam map includes a correspondence between first information and beam reports, wherein the first information is information used to determine the location of the terminal.

It is understood that a beammap can include a correspondence between each piece of first information and a beam report. Specifically, one piece of first information can correspond to one or more beam reports, and one beam report can correspond to one or more pieces of first information.

In some embodiments, the first information may include at least one of the following: the current position of the terminal; the position of the terminal; the relative position of the terminal; the starting position of the terminal; the target position of the terminal; the relative distance between the current position and the starting position of the terminal; the relative direction between the current position and the starting position of the terminal; the route selected by the terminal; the time taken for the terminal to move from the starting position to the current position; the moving speed of the terminal; and the current time.

In some embodiments, the terminal's starting location may be, for example, home or office; the terminal's target location may be, for example, office or home; the route selected by the terminal may be a route from the starting location to the target location (e.g., a route by public transport, a driving route, a cycling route, etc.); the time taken for the terminal to move from the starting location to the current location may be the time interval between the time the terminal spends at the starting location and the time it spends at the current location; and the terminal's moving speed may be the average speed at which the terminal moves from the starting location to the current location. For example, the first information includes the terminal's location, and the beam map includes the correspondence between the terminal's location and beam reports. After the terminal obtains its actual location, a beam report corresponding to the terminal's actual location can be obtained based on the beam map. The terminal's location can also be called an absolute location, which is not a relative location relative to a certain other location. The terminal's location may include its latitude and longitude information.

The location of the terminal can be determined by a positioning method, and this disclosure does not limit this.

The location of the terminal can be determined based on the terminal's current location, or based on the terminal's starting location, the relative distance between the terminal's current location and the terminal's starting location, or based on the terminal's starting location, the time it takes for the terminal to move from the starting location to the current location, and the terminal's moving speed. This disclosure does not limit the determination of these factors.

For example, the first piece of information includes the terminal's relative position, and the beam map includes the correspondence between the terminal's relative position and the beam report. After the terminal obtains its actual relative position, it can obtain the beam report corresponding to the terminal's actual relative position based on the beam map.

For example, a terminal can also obtain its position based on its relative and starting positions. The beam map includes the correspondence between the terminal's position and beam reports. After the terminal obtains its actual position, it can obtain a beam report corresponding to its actual position based on the beam map.

The relative position of the terminal can be the relative position between the terminal's current actual position and its starting position. The relative position of the terminal can be determined based on the terminal's current position and its starting position, or based on the relative distance between the terminal's current position and its starting position, or based on the time it takes for the terminal to move from its starting position to its current position and the terminal's moving speed. This disclosure does not limit this determination.

For example, the first piece of information includes the route selected by the terminal, and the beam map includes the correspondence between the route selected by the terminal and the beam report. After the terminal obtains the route actually selected by the terminal, it can obtain the beam report corresponding to the route actually selected by the terminal based on the beam map.

For example, the first piece of information includes the time taken to move from the starting position to the current position and the terminal's moving speed. The beam map includes the correspondence between the time taken to move from the starting position to the current position, the terminal's moving speed, and the beam report. After the terminal obtains the actual time taken to move from the starting position to the current position and the actual moving speed, it can obtain the corresponding beam report based on the beam map.

For example, a terminal can obtain its relative position based on the time taken to move from its starting position to its current position, its moving speed, and its route. Then, it can obtain its actual position based on the relative position and the starting position. The beam map includes the correspondence between the terminal's position and the beam report. After the terminal obtains its actual position, it can obtain the beam report corresponding to its actual position based on the beam map.

For example, the first piece of information includes the current time, and the beam map includes the correspondence between the current time and the beam report. After the terminal obtains the actual current time, it can obtain the beam report corresponding to the actual current time based on the beam map.

For example, a terminal can obtain its relative position based on the current time and route, and then obtain its actual location based on the relative position and the starting position. The beam map includes the correspondence between the terminal's location and beam reports. After the terminal obtains its actual location, it can obtain a beam report corresponding to its actual location based on the beam map. For example, if the terminal is traveling by public transportation (such as a subway), the route and its location at each time are fixed.

In some embodiments, a terminal may obtain a beam map through at least one of the following methods: the terminal generates a beam map; the terminal downloads a beam map from the Internet; the terminal downloads the beam map from a terminal-side server; or the terminal receives the beam map sent by a network device.

In some embodiments, the beam map is generated based on the beam measurement results of the terminal and the first information corresponding to the beam measurement results.

In some embodiments, the beam map may be generated based on an artificial intelligence (AI) model.

The above step S2101 may include any one of steps S2101a, S2101b, and S2101c.

Step S2101a: The network device sends a beam map to the terminal.

In some embodiments, the terminal can send the terminal's beam measurement results and the first information corresponding to the beam measurement results (e.g., via beam reports) to the network device. The network device generates a beam map based on the terminal's beam measurement results and the first information corresponding to the beam measurement results, and then sends the beam map to the terminal.

Step S2101b: The terminal-side server sends a beam map to the terminal.

In some embodiments, the terminal can send the beam measurement results of the terminal and the first information corresponding to the beam measurement results to the terminal-side server. The terminal-side server generates a beam map based on the beam measurement results of one or more terminals and the first information corresponding to the beam measurement results, and then sends the beam map to the terminal.

The terminal-side server interacts with one or more terminals to generate beam maps. When the beam map needs updating, the terminal-side server updates the beam map and sends the updated beam map to each terminal that has interacted with it. The terminal-side server may be invisible to network devices, meaning it does not interact with network devices.

Step S2101c: The terminal generates a beam map.

In some embodiments, the terminal may generate a beam map based on the terminal's beam measurement results and the first information corresponding to the beam measurement results.

In other embodiments, the terminal may also upload the terminal's beam measurement results and the first information corresponding to the beam measurement results to the Internet. The Internet generates a beam map based on the terminal's beam measurement results and the first information corresponding to the beam measurement results, and the terminal can download the beam map from the Internet.

In this embodiment of the disclosure, terminals located in the same geographical location (or the same geographical area) use essentially the same beam. Therefore, if beam measurement has been performed for that geographical location before, the terminal can use the previous beam measurement results when it is in that geographical location again, thereby reducing the number of times the terminal needs to perform beam measurement.

In this embodiment of the present disclosure, a beam map is generated based on the beam measurement results of the terminal and the first information corresponding to the beam measurement results. When the terminal needs to perform beam measurement, the corresponding beam report can be determined in the beam map based on the actual first information of the terminal. The beam report is then reported to the network, which can reduce the number of times the terminal performs beam measurement.

In this embodiment of the disclosure, for users of terminals with regular travel patterns, the corresponding beam report can be obtained from the beam map based on the relative position of the terminal's current actual position and starting position or the current time, and the beam report can be used as the beam report reported to the network device, which can reduce the number of times the terminal performs beam measurement.

For example, users whose work hours and routes to and from work are relatively fixed on weekdays will be located at roughly the same time each day (e.g., 8:30). They can obtain the corresponding beam report from the beam map based on the current actual time.

In some embodiments, the beam report may include at least one of the following: an identifier of at least one reference signal resource; and at least one quality information. The identifier of the reference signal resource may be, for example, at least one of a Synchronization Signal and PBCH block (SSB) identifier (ID) and a Channel State Information Reference Signal (CSI-RS) ID. The quality information may be, for example, at least one of Layer 1 reference signal receiving power (L1-RSRP) and Layer 1 signal-to-interference-plus-noise ratio (L1-SINR). The reference signal resource identifier can be used to represent the transmit beam of the network-side device.

In step S2102, the terminal determines the actual first information.

In some embodiments, the actual first information is used to determine the current actual location of the terminal.

In some embodiments, the actual first information corresponds to the first information in the beammap. For example, the first information in the beammap is the terminal's position, while the actual first information is the terminal's actual position. For example, the first information in the beammap is the relative distance between the terminal's current position and its starting position, while the actual first information is the relative distance between the terminal's current actual position and its starting position. For example, the first information is the time it takes for the terminal to move from its starting position to its current position and the terminal's moving speed, while the actual first information is the time it takes for the terminal to move from its starting position to its current actual position and the terminal's actual moving speed.

In step S2103, the terminal determines the first beam report corresponding to the actual first information based on the correspondence relationship.

In some embodiments, the terminal can determine the beam report corresponding to the actual first information from the beam map. For ease of description, the beam report corresponding to the actual first information determined from the beam map is referred to as the first beam report.

In some embodiments, the first beam report may include at least one reference signal resource identifier and its corresponding quality information. For ease of description, the reference signal resource identifier included in the first beam report is referred to as the first reference signal resource identifier, the reference signal corresponding to the first reference signal resource identifier is referred to as the first reference signal, and the quality information corresponding to the first reference signal resource identifier is referred to as the first quality information.

Step S2104: The terminal sends a beam report to the network device.

In some embodiments, the terminal may send a beam report to the network device based on the first beam report.

In some embodiments, the terminal can directly send the first beam report to the network device, that is, the terminal does not need to perform beam measurement on the reference signal resources sent by the network device, which can reduce the number of times the terminal performs beam measurement, thereby reducing the power consumption of the terminal.

In some embodiments, the terminal may measure the first reference signal corresponding to at least one first reference signal resource identifier in the first beam report, and determine the accuracy of the first beam report based on the measurement result of the first reference signal, thereby determining the beam report to be sent to the network device.

In some embodiments, the terminal measures the first reference signal to obtain quality information of the first reference signal. For ease of description, the quality information of the first reference signal obtained by the terminal measurement is referred to as second quality information.

In some embodiments, by comparing the quality value corresponding to the first quality information (quality information in the first beam report) and the quality value corresponding to the second quality information (quality information obtained by the terminal in this measurement), the accuracy of the first beam report can be determined, thereby determining whether to send the first beam report to the network device or to perform beam measurement and send the second beam report based on more reference signal resources sent by the network device.

In some embodiments, when the difference between the quality value corresponding to the first quality information and the quality value corresponding to the second quality information meets a difference condition, the terminal sends a first beam report obtained from the beam map to the network device. When the difference between the measured quality value and the quality value in the first beam report meets the difference condition, it indicates that the first beam report obtained from the beam map is highly accurate. The terminal does not need to perform further beam measurements and can directly send the first beam report obtained from the beam map to the network device. This reduces the number of beam measurements performed by the terminal while ensuring the accuracy of the beam report, thereby reducing the terminal's power consumption.

In some embodiments, when the difference between the quality value corresponding to the first quality information and the quality value corresponding to the second quality information does not meet the difference condition, the terminal performs measurements based on the reference signal resources sent by the network device to obtain a second beam report, and the terminal sends the second beam report to the network device. The reference signal resources sent by the terminal based on the network device include the reference signal resources included in the first beam report. The reference signal resources sent by the network device can be reference signal resources in the reference signal resource configuration set sent by the network device, that is, reference signal resources used by the terminal for measurement.

In some embodiments, when the measured quality value and the quality value in the first beam report do not meet the difference condition, the terminal performs beam measurement on the reference signal resources sent by the network device to ensure the accuracy of the beam report.

In some embodiments, satisfying the difference condition means that the difference is less than a threshold value, and not satisfying the difference condition means that the difference is greater than or equal to the threshold value. The size of the threshold value can be set according to actual conditions, and this disclosure does not limit it.

For example, the L1-RSRP or L1-SINR of the first reference signal obtained by the terminal measurement can be compared with the L1-RSRP or L1-SINR of the first reference signal in the first beam report. If the difference is within the threshold value, the terminal sends the first beam report to the network device; otherwise, the terminal performs beam measurement based on the reference signal resources sent by the network device to obtain the second beam report, and the terminal sends the second beam report to the network device.

In step S2105, the terminal sends a second beam report to the terminal-side server.

In some embodiments, the terminal obtains a beam map from the terminal-side server. After receiving the second beam report, the terminal sends the second beam report to the terminal-side server. The second beam report is used by the terminal-side server to update the beam map of the terminal-side server.

In some embodiments, the terminal can obtain an updated beam map from the terminal-side server.

In the above embodiments, after the terminal performs beam measurement on the reference signal resources sent by the network device to obtain a second beam report, it sends the second beam report to the terminal-side server so that the terminal-side server can update the beam map and ensure the real-time performance and accuracy of the beam map.

The communication method provided in this embodiment allows a terminal to acquire a beam map. The beam map includes a correspondence between first information used to determine the terminal's location and beam reports. This enables the terminal to obtain beam reports corresponding to its location information based on the beam map, reducing the number of beam measurements performed by the terminal and thus lowering its power consumption.

This disclosure provides a communication method that may include a method for generating and using a beam map based on artificial intelligence (AI), which can reduce terminal beam measurements and ensure the accuracy of beam reporting and low latency.

In some embodiments, the terminal obtains a beam map, which includes a correspondence between first information and beam reports. The first information may include at least one of the following: the terminal's current location, the terminal's starting location, the terminal's target location, the relative distance and/or direction between the terminal's current location and the starting location, the route selected by the terminal (e.g., the route between the terminal's starting location and the target location), the time interval between the terminal's current location and the starting location (i.e., the time elapsed from the starting location to the current location), the terminal's moving speed, and the current time (e.g., morning commute or afternoon commute).

In some embodiments, the current position of the terminal may refer to the terminal's location or its relative position.

In some embodiments, the beam map may include a correspondence between the location of the terminal and the beam report.

In other embodiments, the beam map may include a correspondence between the relative position of the terminal and beam reports. For example, the relative position of the terminal may be the relative position between the terminal's current position and its starting position.

In some embodiments, the beam map may include a correspondence between the terminal's starting location and the beam report. For example, the terminal's starting location may be the location of the terminal user's home, or it may be the location of the terminal user's company.

In some embodiments, the beam map may include a correspondence between the terminal's target location and beam reports. For example, the terminal's target location could be the location of the terminal user's company, or it could be the location of the terminal user's home. Place.

In some embodiments, the beam map may include a correspondence between the relative position of the terminal's current position and its starting position and the beam report. The relative position of the terminal's current position and its starting position may include the relative distance and/or direction between the two positions. The relative position of the terminal's current position and its starting position can be determined by the time elapsed from the starting position to the current position and the terminal's moving speed, for example, by multiplying the time elapsed from the starting position to the current position by the terminal's moving speed.

In some embodiments, the beam map may include a correspondence between the route selected by the terminal (such as the route between the terminal's starting position and the target position) and the beam report.

In some embodiments, the beam map may include the correspondence between the time interval between the terminal's current location and the starting location (i.e., the time elapsed from the starting location to the current location) and the beam report.

In some embodiments, the beam map may include a correspondence between the terminal’s movement speed and beam reports.

In some embodiments, the beam map may include the time interval between the terminal's current position and its starting position, and the correspondence between the terminal's moving speed and the beam report.

In some embodiments, the beam map may include a correspondence between the current time and the beam report.

In some embodiments, a beam report may include at least one of the following: an identifier of at least one reference signal resource, and/or at least one quality information. The identifier of the reference signal resource may be, for example, at least one of SSB ID and CSI-RS ID. The quality information may be, for example, at least one of L1-RSRP and L1-SINR.

In some embodiments, the terminal can obtain the above-mentioned beam map in the following manner.

In one example, the terminal can generate the beam map itself, or the terminal can download the beam map from the internet, or the terminal can download the beam map from a terminal-side server.

For example, the terminal has a unified server. The server first collects the beam measurement results (e.g., beam reports) and corresponding first information from the terminal. Then, it generates a beam map based on the beam reports and first information from at least one terminal and sends the beam map to each terminal.

In this case, the terminal sends the traditional beam measurement results and the corresponding first information to the terminal-side server, which is invisible to the network-side devices.

If multiple terminals are located in the same area but their beam measurement results in the beam reports are different, it's equivalent to the same first information corresponding to multiple different beam reports. In this case, the server can determine the beam report corresponding to the first information based on the order in which the beam measurement results were reported (e.g., selecting the beam report with the later reporting time), or the server can determine the beam report corresponding to the first information based on the number of terminals that reported the beam measurement results (e.g., selecting the beam report corresponding to the number of reported beam measurement results).

In one example, the terminal can receive a beam map sent by the base station or the core network.

For example, the terminal first sends the traditional beam measurement results and the corresponding first information to the base station or core network. The base station or core network generates a beam map based on the measurement results of at least one terminal, and then sends the beam map to the terminal.

In some embodiments, the terminal may use the above beam map in the following manner.

In some embodiments, the terminal determines the current first information (e.g., current actual location, current relative location, current time, current moving speed, etc.) and obtains the beam report based on the correspondence between the first information in the beam map and the beam report.

In one example, the terminal directly sends the beam report obtained based on the beam map to the network device.

In one example, the terminal measures the reference signal corresponding to at least one reference signal resource identifier in the beam report obtained based on the beam map, and compares the L1-RSRP/L1-SINR corresponding to the obtained reference signal with the L1-RSRP/L1-SINR corresponding to the reference signal in the beam map. If the difference between the two is within a threshold, the terminal directly sends the beam report obtained based on the beam map to the network device; otherwise, the terminal measures the L1-RSRP/L1-SINR corresponding to more reference signal resources sent by the network device, obtains the latest beam report based on the measurement results, and sends the latest beam report to the network.

If a new beam report is obtained based on measurements of more reference signal resources, the terminal can send it to the terminal-side server, allowing the server to update the beam map. The terminal can then retrieve the updated beam map from the terminal-side server, the network, or the internet.

The AI-based beam map provided in this disclosure can reduce terminal beam measurement and reduce terminal power consumption.

In the embodiments disclosed herein, some or all of the steps and their optional implementations may be arbitrarily combined with some or all of the steps in other embodiments, or may be arbitrarily combined with the optional implementations in other embodiments.

This disclosure also provides an apparatus for implementing any of the above methods. For example, an apparatus is provided that includes units or modules for implementing the steps performed by the terminal in any of the above methods. Alternatively, another apparatus is provided that includes units or modules for implementing the steps performed by a network device (e.g., an access network device, a core network functional node, a core network device, etc.) in any of the above methods.

It should be understood that the division of units or modules in the above device is only a logical functional division. In actual implementation, they can be fully or partially integrated into a single physical entity, or they can be physically separated. Furthermore, the units or modules in the device can be accessed by a processor calling software... Formal Implementation: For example, the device includes a processor connected to a memory containing instructions. The processor calls the instructions stored in the memory to implement any of the above methods or to implement the functions of each unit or module of the device. The processor is, for example, a general-purpose processor, such as a Central Processing Unit (CPU) or a microprocessor, and the memory is either internal or external to the device. Alternatively, the units or modules in the device can be implemented as hardware circuits. The functions of some or all units or modules can be implemented through the design of the hardware circuits, which can be understood as one or more processors. For example, in one implementation, the hardware circuit is an application-specific integrated circuit (ASIC). The functions of some or all units or modules are implemented through the design of the logical relationships between the components within the circuit. In another implementation, the hardware circuit can be implemented using a programmable logic device (PLD), such as a Field Programmable Gate Array (FPGA). This PLD can include a large number of logic gates, and the connection relationships between the logic gates are configured through a configuration file to implement the functions of some or all units or modules. All units or modules of the above devices can be implemented entirely through processor calling software, or entirely through hardware circuits, or partially through processor calling software with the remaining parts implemented through hardware circuits.

In this embodiment, the processor is a circuit with signal processing capabilities. In one implementation, the processor can be a circuit with instruction read and execute capabilities, such as a Central Processing Unit (CPU), a microprocessor, a graphics processing unit (GPU) (which can be understood as a microprocessor), or a digital signal processor (DSP). In another implementation, the processor can implement certain functions through the logical relationships of hardware circuits. The logical relationships of the aforementioned hardware circuits are fixed or reconfigurable. For example, the processor is a hardware circuit implemented using an application-specific integrated circuit (ASIC) or a programmable logic device (PLD), such as an FPGA. In a reconfigurable hardware circuit, the process of the processor loading a configuration document and configuring the hardware circuit can be understood as the process of the processor loading instructions to implement the functions of some or all of the above units or modules. In addition, it can also be hardware circuits designed for artificial intelligence, which can be understood as ASICs, such as Neural Network Processing Unit (NPU), Tensor Processing Unit (TPU), Deep Learning Processing Unit (DPU), etc.
