[0002] This disclosure is based on and claims priority to Chinese patent application CN202410849869.7, filed on June 27, 2024, entitled “A Processing Method for Perception-Assisted Communication”, the entire contents of which are incorporated herein by reference. Technical Field

[0003] This disclosure relates to the field of wireless communication technology, and more specifically, to a processing method for sensing-assisted communication. Background Technology

[0004] Mobile users, especially high-speed mobile users, do not receive accurate frequency offset information during the access phase, making timely frequency offset compensation impossible. This results in significant access latency and a low access success rate. The same applies to cell handover, leading to prolonged handover latency and a low handover success rate. For base station communication cells, regardless of whether a fixed wide or narrow beam is configured, the corresponding generation weights, number of beams, and coverage area are fixed, resulting in imprecise control. For a specific mobile user, the beam is always too wide.

[0005] No solution has yet been proposed to address the issues that high-speed mobile users cannot receive timely frequency offset compensation in related technologies, resulting in large access or handover delays, low success rates, and fixed beam counts and coverage areas, leading to imprecise control.

[0028] This embodiment provides a processing method for perception-assisted communication running on the aforementioned computer device. Figure 2 is a flowchart of the processing method for perception-assisted communication according to an embodiment of this disclosure. As shown in Figure 2, the process includes the following steps:

[0029] Step S202: Receive detection information of moving targets sensed by the sensing cell;

[0030] Step S204: Perform beam adjustment and / or frequency offset pre-compensation based on the detection information.

[0031] Through the above steps S202 to S204, the problems in related technologies, such as the inability of high-speed mobile users to perform frequency offset compensation in a timely manner, resulting in large access or handover delays, low success rates, and fixed beam counts and coverage areas with insufficient control, can be solved. Based on the detection information obtained from the sensing cell, frequency offset pre-compensation is performed on the access or handover signals, thereby improving the success rate of cell access and handover for the mobile user in the communication cell and reducing the cell access and handover delays for the mobile user; and it can adaptively adjust the downlink beam coverage of the communication cell.

[0032] Figure 3 is a flowchart of a processing method for perception-assisted communication according to an optional embodiment of the present disclosure. As shown in Figure 3, step S204 may specifically include:

[0033] Step S302: Determine the Doppler frequency offset value of the moving target relative to the base station based on the detection information;

[0034] Step S304: When a mobile target accesses or switches to a communication cell, frequency offset pre-compensation is performed on the uplink signal and / or downlink signal based on the Doppler frequency offset value.

[0035] The Doppler frequency offset value in step S302 above can be obtained directly from the detection information or calculated based on the detection information. Specifically, if the detection information includes the Doppler frequency offset value generated when the mobile target accesses or switches to the communication cell, the Doppler frequency offset value generated by the mobile target relative to the base station is obtained from the detection information; or the Doppler frequency offset value generated by the mobile target relative to the base station is determined based on the detection information. The Doppler frequency offset value in the detection information is calculated by the sensing cell. Specifically, the Doppler frequency offset value can be calculated as follows: f = (v*f0) / (c*cosθ), where f is the Doppler frequency offset value, f0 is the carrier frequency, c is the transmission speed of electromagnetic waves, v is the moving speed of the mobile target, and θ is the angle between the direction of the mobile target and the signal propagation direction of the base station. Alternatively, the Doppler frequency offset value can be calculated as follows: calculate the phase difference Δφ of the sensing signal within a fixed time Δt, and then use the formula f = Δφ / (2π*Δt).

[0036] In one embodiment, determining the Doppler frequency offset value of the moving target relative to the base station based on the detection information may specifically include: obtaining the position of the moving target, the angle between the moving target's direction of movement and the signal propagation direction of the base station, and the moving speed of the moving target from the detection information; determining the moving direction of the moving target based on the position of the moving target; and calculating the Doppler frequency offset value based on the angle between the moving target's direction of movement and the signal propagation direction of the base station, as well as the moving speed.

[0037] In another embodiment, calculating the Doppler frequency offset value of the moving target relative to the base station based on the detection information may further include: obtaining the carrier frequency and the transmission speed of electromagnetic waves; and determining the Doppler frequency offset value based on the Doppler principle, according to the moving speed of the moving target, the angle between the moving target's direction of movement and the signal propagation direction of the base station, the carrier frequency, and the transmission speed of electromagnetic waves. Further, the Doppler frequency offset value can be determined in the following ways:

[0038] f = (v*f0) / (c*cosθ), where f is the Doppler frequency offset, f0 is the carrier frequency, c is the transmission speed of electromagnetic waves, v is the moving speed of the moving target, and θ is the angle between the direction of the moving target and the signal propagation direction of the base station.

[0039] In one embodiment, the Doppler frequency offset value is filtered using historical Doppler frequency offset values. Specifically, filtering can be performed based on pre-set filtering coefficients, for example, for f' = α*f + (1-α)*f d f' is the filtered Doppler frequency offset value, f d This represents the historical Doppler frequency offset value.

[0040] Furthermore, the method also includes updating the filtered Doppler frequency offset value to the historical Doppler frequency offset value.

[0041] In this embodiment of the present disclosure, step S204, which involves adjusting the beam based on the detection information, specifically adjusting the downlink beam, may include:

[0042] S2041, Obtain the position of the moving target, the angle between the moving target's direction of movement and the signal propagation direction of the base station, and the moving speed of the moving target from the detection information;

[0043] S2042, adjust downlink beam coverage according to the location of the moving target, the angle between the moving target's direction of movement and the base station's signal propagation direction, and the moving speed of the moving target.

[0044] Furthermore, S2042 may specifically include: adjusting the beamwidth and azimuth angle of the beam covering the moving target based on the location of the moving target, the angle between the moving target's direction of movement and the signal propagation direction of the base station, and the moving speed of the moving target; transmitting a downlink beam according to the adjusted beamwidth and azimuth angle of the beam covering the moving target, so that the beam covers the moving target. The beam coverage adjustment process may include: after receiving a moving target from the sensing cell, the communication cell periodically adjusts the beamwidth and azimuth angle of the beam used to cover the moving target based on the target's location and speed information, and schedules the transmission of the beam during the beam transmission period, so that the beam covers the moving target. Other beams are used based on the same principle to cover targets with low movement speed or stationary locations in other parts of the communication cell.

[0045] In one embodiment, the method further includes: transmitting the frequency-off pre-compensated downlink signal after performing frequency offset pre-compensation on the downlink signal based on the Doppler frequency offset value; or performing channel estimation after performing frequency offset pre-compensation on the uplink signal based on the Doppler frequency offset value.

[0046] This embodiment of the disclosure detects and obtains the location, angle, and speed information of a mobile user in a sensing cell, and then sends this information to communication cells with the same beam coverage or adjacent cells. The communication cell can adaptively adjust the number of downlink beams and beam weight generation parameters accordingly, reducing redundant coverage while using a narrower beam to cover the mobile user. Furthermore, it can calculate the Doppler frequency offset value generated by the mobile user during access or handover. At the beginning of the actual access or handover process, the calculated Doppler frequency offset value can be used to pre-compensate the frequency offset of the incoming signal, thereby improving the success rate of cell access and handover in the communication cell and reducing the latency of cell access and handover. Furthermore, the specific process of frequency offset pre-compensation may include: for uplink frequency offset pre-compensation, after converting the air interface signal into a frequency domain signal, frequency offset pre-compensation is performed on the frequency domain position of the communication signal of the mobile target, and then channel estimation and channel equalization are performed on the signal; for downlink frequency offset pre-compensation, after the frequency domain data resource block mapping and modulation shaping are converted to the time domain by IFFT, frequency offset pre-compensation is performed, and then the air interface signal is transmitted.

[0047] By leveraging prior information about mobile users obtained from sensing cells, the downlink beam coverage of communication cells can be optimized to improve uplink reception and downlink transmission performance during cell access and handover. Based on a sensing cell under an integrated sensing base station, sensing target detection technology is used to obtain the Range-Doppler map of the mobile target and its angle information relative to the base station, and this information is continuously transmitted to neighboring or co-located co-frequency communication cells. The communication cell uses this information to dynamically and adaptively adjust its downlink beam coverage and pre-estimates the Doppler frequency offset value of the mobile user relative to the base station. When a user accesses or hands over to a cell of this base station, the base station can use this Doppler frequency offset value to perform frequency offset pre-compensation for uplink and downlink signals. This mainly includes:

[0048] Step 1: Activate communication cells and sensing cells that include integrated communication and sensing base stations.

[0049] Step 2: Create a sensing task in the sensing cell. The sensing cell periodically detects and identifies information such as the angle, speed and position of moving targets.

[0050] Step 3: After the sensing cell confirms that a moving target has been detected, the above information is continuously sent to the relevant communication cell.

[0051] Step 4: Based on the target's sensing and detection information (angle, speed, and position), the communication cell can determine the target's direction of movement, angle, and speed, and calculate and maintain the Doppler frequency offset value generated by the target during cell access or cell handover.

[0052] Step 5: The communication cell performs near-frequency offset pre-compensation based on the Doppler frequency offset value.

[0053] In one embodiment, frequency offset pre-compensation is performed on high-speed rail users in the communication cell using frequency offset information from the sensing cell, specifically including:

[0054] 1. Create sensing tasks in the sensing community.

[0055] 2. After the sensing cell confirms the detection of the high-speed rail, it continuously estimates the channel of the sensing signal and calculates the phase difference Δφ of the sensing signal within a fixed time Δt. Then, it calculates the corresponding frequency offset using the formula f=Δφ / (2π*Δt) and sends the frequency offset information to the relevant communication cell. The frequency offset information includes the Doppler frequency offset value.

[0056] 3. The communication cell filters the currently calculated Doppler frequency offset value and the historical Doppler frequency offset value to obtain the filtered Doppler frequency offset value f' = α*f + (1-α)*f d α is a pre-set filter coefficient.

[0057] The filtered Doppler frequency offset value is used for frequency offset pre-compensation of the uplink and downlink signals of the high-speed rail. For the downlink signal, pre-compensation is performed on the downlink time domain signal, and for the uplink signal, pre-compensation is performed on the frequency domain signal after the high-speed rail UE access.

[0058] In another embodiment, frequency offset pre-compensation is performed on high-speed rail users under the communication cell using the angle, speed, and location information of the sensing cell, specifically including:

[0059] 1. Create sensing tasks in the sensing community.

[0060] 2. After the sensing cell confirms the detection of the high-speed rail, it continuously sends information such as the angle, speed, and location of the high-speed rail relative to the base station under the integrated sensing and communication system to the relevant communication cells.

[0061] 3. The communication cell can determine the target's direction of movement based on changes in the high-speed rail's location information. Using the angle and speed information obtained each time, it calculates the corresponding Doppler frequency offset value f = (v*f0) / (c*cosθ) according to the Doppler principle. This calculated Doppler frequency offset value is then used for frequency offset pre-compensation of the high-speed rail's uplink and downlink signals. For downlink signals, pre-compensation is performed in the downlink time domain; for uplink signals, pre-compensation is performed in the frequency domain signal after the high-speed rail's access.

[0062] In yet another embodiment, frequency offset pre-compensation is performed on high-speed rail users within the communication cell using the angle, speed, and location information of the sensing cell. Specifically, this includes:

[0063] 1. Create sensing tasks in the sensing community.

[0064] 2. After the sensing cell confirms the detection of the high-speed rail, it continuously sends information such as the angle, speed, and location of the high-speed rail relative to the base station under the integrated sensing and communication system to the relevant communication cells.

[0065] 3. The communication cell can determine the target's direction of movement based on changes in the high-speed rail's location information. Using the angle and velocity information obtained each time, it calculates the corresponding Doppler frequency offset value f = (v*f0) / (c*cosθ) according to the Doppler principle. The currently calculated Doppler frequency offset value is then filtered along with historical Doppler frequency offset values ​​to obtain the filtered Doppler frequency offset value f' = α*f + (1-α)*f d α is a pre-set filtering coefficient. The filtered Doppler frequency offset value is used for frequency offset pre-compensation of the uplink and downlink signals of the high-speed rail. For the downlink signal, pre-compensation is performed on the downlink time domain signal; for the uplink signal, pre-compensation is performed on the frequency domain signal after the high-speed rail UE access.

[0066] Figure 4 is a schematic diagram of beam adaptive adjustment to cover mobile users according to an embodiment of the present disclosure. As shown in Figure 4, the communication cell can also determine the number of downlink beams to be generated, as well as the beamwidth and azimuth information of the corresponding beams, based on the sensing and detection information (position, speed, angle) of the mobile target. The downlink beams are transmitted according to this information so that there is always a narrower beam that can cover the mobile user.

[0067] The beam coverage adjustment process may include: after receiving a moving target from the sensing cell, the communication cell periodically designs the horizontal bandwidth, vertical bandwidth, azimuth angle, and downtilt angle of the SSB (Synchronization Signal Block) beam and CSIRS (Channel State Information Reference Signal) beam to cover the moving target based on the target's location and speed information. This beam is then scheduled for transmission during the SSB and CSIRS transmission cycles. Other beams, based on the same design principles, are used to cover users with lower movement speeds or those that are stationary in other locations within the communication cell. Downlink beam management using sensing information specifically includes:

[0068] 1. Create sensing tasks in the sensing community.

[0069] 2. Assume that after the sensing cell confirms the detection of two moving targets, it continuously sends the angle, speed and location information of the two moving targets to the relevant communication cell.

[0070] 3. Assuming a communication cell transmits 7 SSBs in one broadcast cycle and has 4 CSIRS beams used for PMI (Precoding Matrix Indicator) measurement in one CSIRS cycle, the communication cell can direct two narrow beams of the downlink beams from the SSBs and two from the CSIRS beams towards the two mobile targets respectively, while using the other beams for low-speed or static users. Based on the position and speed information of the two mobile targets, the horizontal and vertical beamwidths, azimuth angles, and downtilt angles of the covering beams are adjusted so that the two mobile targets always have narrower SSB or CSIRS beams to cover them, whether they are accessing the network or conducting services.

[0071] 4. Subsequently, the Doppler frequency offset value determined by any of the above methods can be used for frequency offset pre-compensation processing.

[0072] Figure 5 is a schematic diagram of beam adaptive adjustment coverage of mobile users according to an embodiment of the present disclosure. As shown in Figure 5, when a mobile user accesses or switches to the communication cell, the communication cell begins to perform frequency offset pre-compensation on the downlink signal using a determined Doppler frequency offset value before transmitting it. The Doppler frequency offset value used for the accessed uplink signal is also pre-compensated before subsequent channel estimation and other operations are performed.
