Abstract
Description
Sensing signal processing methods, communication nodes and storage media Technical Field
[0001] This application relates to the field of wireless communication technology, such as a sensing signal processing method, a communication node, and a storage medium. Background Technology
[0002] With the continuous development of communication technology, communication networks will be able to support sensing functions. To avoid severe self-interference problems, base station sensing often adopts pulse transmission.

[0023] The present application will now be described in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are merely illustrative of the application and not intended to limit it. It should be noted that, unless otherwise specified, the embodiments and features described herein can be arbitrarily combined with each other. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present application, not the entire structure.
[0024] Figure 1 is a flowchart of a sensing signal processing method according to an embodiment. This method can be applied to communication nodes, such as base stations or terminals. As shown in Figure 1, the method provided in this embodiment includes:
[0025] Step 110: Transmit the first pulse sensing signal;
[0026] Step 120: Receive the first pulse sensing signal reflected by the sensing target;
[0027] Step 130: Transmit a second pulse sensing signal, the pulse width of which is different from that of the first pulse sensing signal;
[0028] Step 140: Receive the second pulse sensing signal reflected by the sensing target;
[0029] Step 150: Determine the perception result of the target based on the first pulse sensing signal and the second pulse sensing signal.
[0030] This application's embodiments primarily address the scenario where the sensing signal contains pulses. Within a single sensing resource, a communication node can transmit sensing signals with pulse widths of T1 and T2, where T2 ≠ T1. Taking T2 > T1 as an example, a pulse with a pulse width of T1 can be used to achieve a smaller pulse sensing blind zone, while a pulse with a pulse width of T2 can be used to increase received energy to ensure coverage.
[0031] Depending on the needs of the sensing task, bandwidth can be allocated to pulses of different widths. For example:
[0032] If the bandwidth of the first pulse sensing signal is equal to the bandwidth of the second pulse sensing signal, the same distance resolution can be achieved. The advantage of this configuration is that it is relatively simple and convenient for allocating resources.
[0033] If the bandwidth of the first pulse sensing signal is greater than that of the second pulse sensing signal, then the first pulse sensing signal can achieve high resolution at close range, and the second pulse sensing signal can achieve long-range sensing by using power boosting. The advantage of this configuration is that it is suitable for scenarios with higher requirements for close-range resolution.
[0034] If the bandwidth of the first pulse sensing signal is less than that of the second pulse sensing signal, then the first pulse sensing signal can be used to achieve low-overhead sensing, while the second pulse sensing signal can be used for high-precision sensing. The advantage of this configuration is that, under limited resource constraints, more power and bandwidth resources can be allocated to long distances to ensure coverage.

[0045] Continuous waves are transmitted using at least one symbol.
[0046] In one embodiment, the first pulse sensing signal is transmitted through at least two consecutive first symbols, each of which corresponds to a different bandwidth resource;
[0047] The second pulse sensing signal is transmitted through at least two consecutive second symbols, each of which corresponds to a different bandwidth resource.
[0048] In one embodiment, the first pulse sensing signal is transmitted through one of two consecutive symbols; the second pulse sensing signal is transmitted through the other of the two consecutive symbols; and the bandwidth resources corresponding to each symbol are different.
[0049] In one embodiment, the method further includes:
[0050] S1010, Receive sensing request;
[0051] S1020. If the variable pulse width pulse transmission mode is determined to be adopted based on the perception request, the resource configuration and signal configuration are determined.
[0052] The resource configuration includes at least one of the following: time-domain start position, frequency-domain start position, time-domain repetition period, number of time-domain repetitions, and frequency-domain bandwidth;
[0053] The signal configuration includes at least one of the following: the number of variable pulse width pulses, and the pulse width of the variable pulse width pulses.
[0054] In one embodiment, determining the perception result of the perceived target based on the first pulse sensing signal and the second pulse sensing signal includes:
[0055] The first sensing information of the sensing target is determined based on the first pulse sensing signal;
[0056] The second sensing information of the sensing target is determined based on the second pulse sensing signal;
[0057] The first perception information and the second perception information are combined to obtain the perception result of the perception target.
[0058] In one embodiment, merging the first sensing information and the second sensing information includes one of the following:
[0059] The first sensing information is combined with the second sensing information;
[0060] The first sensed information and the second sensed information are coherently merged;
[0061] The first and second perceived information are merged at the maximum ratio.
[0062] For each blind zone corresponding to the first pulse sensing signal and the second pulse sensing signal, the frequency hopping signals covering the blind zone are coherently combined.
[0063] In one embodiment, the method further includes:
[0064] S1200: After transmitting the first pulse sensing signal and before receiving the first pulse sensing signal reflected by the sensing target, switch from the transmitting state to the receiving state.
[0065] S1300: After receiving the first pulse sensing signal reflected by the sensing target and before transmitting the second pulse sensing signal, switch from the receiving state to the transmitting state.
[0066] S1400: After transmitting the second pulse sensing signal and before receiving the second pulse sensing signal reflected by the sensing target, switch from the transmitting state to the receiving state.
[0067] The following examples illustrate the sensing signal processing method of this application.
[0068] In one embodiment, a communication node (such as a base station or terminal) with wireless sensing capabilities periodically uses spectrum resources for sensing.
[0069] Figure 2 is a schematic diagram of a communication sensing embodiment. As shown in Figure 2, S represents sensing and C represents communication. In a sensing resource, communication nodes can send the same sensing signal, and the signal-to-noise ratio is improved by accumulating energy at the receiving end. The sensing signal can be a pulse, a continuous wave, or both. This embodiment mainly focuses on the case where the sensing signal contains a pulse. Traditional solutions send two sensing signals with a pulse width of T in a sensing resource. In this embodiment, sensing signals with pulse widths of T1 and T2 (a first pulse sensing signal and a second pulse sensing signal) are sent in a sensing resource. For example, T2 is greater than T1. The pulse with a pulse width of T1 can be used to achieve a smaller pulse sensing blind zone, while the pulse with a pulse width of T2 can be used to increase the received energy to ensure coverage.
[0070] Depending on the needs of the sensing task, different bandwidths can be allocated to pulses of different widths, including:
[0071] Case 1: Pulse 1 bandwidth = Pulse 2 bandwidth, used to achieve the same distance resolution. The advantage of this configuration is that it is relatively simple and easy to allocate resources.
[0072] Scenario 2: Pulse 1 bandwidth > Pulse 2 bandwidth: Pulse 1 achieves high resolution at close range, while Pulse 2 utilizes power boosting for long-range sensing. This configuration is suitable for scenarios requiring higher resolution at close range.
[0073] Scenario 3: Pulse 1 bandwidth < Pulse 2 bandwidth. Pulse 1 is used for low-overhead sensing, while Pulse 2 is used for high-precision sensing. The advantage of this configuration is that, under limited resource constraints, coverage can be ensured by allocating more power and bandwidth resources for long-distance travel.
[0074] In one embodiment, the integrated sensing device uses Orthogonal Frequency Division Multiplexing (OFDM) waveforms for transmission, and there are various ways to utilize OFDM waveforms. This embodiment focuses on introducing various implementation methods of variable pulse width transmission.
[0075] Figure 3 is a schematic diagram of transmitting a variable pulse width pulse according to an embodiment. As shown in Figure 3, the implementation of transmitting a variable pulse width pulse includes at least one of the following methods:
[0076] Single Symbol Multipulse: Variable pulse width pulses are implemented within a single Cyclic Prefix (CP) OFDM symbol, as shown in Figure 2. Two pulse signals with different pulse widths are transmitted within a single symbol for sensing.
[0077] Single symbol single pulse: A variable pulse width pulse is transmitted within a single CP-OFDM symbol, as shown in Figure 3. Two pulse signals with different pulse widths are transmitted within two symbols for sensing.
[0078] Multi-symbol single pulse: A variable pulse width pulse is transmitted within multiple CP-OFDM symbols, as shown in Figure 3. Two pulse signals with different pulse widths are transmitted within four symbols for sensing. The first and third symbols in this method are similar to the single-symbol single pulse method. The difference is that the first and second symbols together constitute the pulse signal, and the third and fourth symbols also together constitute the pulse signal. The second and fourth symbols are set to zero.
[0079] Hybrid mode: The above methods can be combined arbitrarily to form a hybrid mode, as shown in Figure 3. It transmits two variable pulse width pulses in the first symbol, a third variable pulse width pulse in the second symbol, and a fourth variable pulse width pulse in the third and fourth symbols.
[0080] In one embodiment, the method for generating a single pulse may include at least one of the following:
[0081] A. Time-domain generation methods, such as using linear frequency modulation (LFM) or ZC (Zadoff-Chu sequence) to generate the pulse with values, and assigning 0 to the pulse without values;
[0082] B. Frequency domain generation methods, such as generating frequency domain data using LFM or ZC with a specific sweep slope;
[0083] C. The time-frequency domain alternating iterative method generates pulses by transforming the pulse in one domain and then processing it in another domain.
[0084] For single-symbol multipulse, the single-pulse generation method described above can be used, and then the generation data of multiple pulses can be superimposed.
[0085] In one embodiment, the pulse width may be greater than or equal to the CP-OFDM symbol width.
[0086] Figure 4 is a schematic diagram of a variable pulse width transmission based on OFDM symbols according to an embodiment. As shown in Figure 4, the pulse can be the symbol length. When the pulse width is greater than or equal to the symbol width, the pulse signal needs to be combined with the subsequent symbols to form a pulse signal. Similarly, the pulse can be twice the symbol length, and it also forms a pulse signal together with the subsequent symbols. In this embodiment, the time-domain or frequency-domain generation method of continuous wave can be used to determine the portion of the pulse with value. The difference from continuous wave sensing signals is that subsequent symbols need to be set to zero to form the pulse signal.
[0087] In one embodiment, the variable pulse width pulse technology and the continuous wave sensing technology can be combined to solve the problem of blind areas existing in pulse signals.
[0088] FIG. 5 is a schematic diagram of a pulse width greater than or equal to the symbol width provided by an embodiment. As shown in FIG. 5, two variable pulse width pulses are transmitted in the first symbol, the third variable pulse width pulse is transmitted in the second symbol, and continuous waves are transmitted in the third and fourth symbols.
[0089] In one embodiment, the variable pulse width pulse technology and the frequency hopping technology can be combined.
[0090] FIG. 6 is a schematic diagram of simultaneous transmission of variable pulse width pulses and continuous wave signals provided by an embodiment. As shown in FIG. 6, narrow pulse signals are transmitted on both the first and second symbols, and the pulse signals occupy different bandwidth resources in these two symbols. Similarly, wide pulse signals are transmitted on the third and fourth symbols, and the pulse signals occupy different bandwidth resources in these two symbols. At the receiving end, the channel estimation results of the first two symbols and the last two symbols can be combined to improve the bandwidth, thereby improving the resolution of distance sensing.
[0091] In one embodiment, the variable pulse width pulse technology and the frequency hopping technology can be combined.
[0092] FIG. 7 is a schematic diagram of frequency hopping transmission of variable pulse width pulse signals provided by an embodiment. As shown in FIG. 7, pulse signals are transmitted in four symbols respectively, and these four pulse signals use different pulse widths w1 < w2 < w3 < w4. After each pulse is transmitted, the wireless node switches to the receiving mode and combines the received signals to obtain a more accurate sensing measurement. Since the pulse widths of different pulses are different, the sizes of the blind areas of each pulse are different, which are d1 < d2 < d3 < d4 respectively. In the range of d1 to d2, only the first pulse can cover, so no combination is performed. In the range of d2 to d3, both the first and second pulses can cover, and the first and second pulses are used for coherent combination. In the range of d3 to d4, the first three pulses can cover, and the first three pulses are used for coherent combination. In the range greater than d4, all four pulses can cover, and all four pulses are used for coherent combination. On this basis, for longer distances, a larger bandwidth and a larger energy can be used for sensing.
[0093] In one embodiment, FIG. 8 is a schematic diagram of the processing flow of frequency hopping transmission and reception of variable pulse width pulse signals provided by an embodiment. As shown in FIG. 8, the processes before and after the variable pulse width signal is transmitted may include:
[0094] ① The sensing function (SF) network element initiates a sensing request to the base station (BS) / user equipment (UE). This sensing request contains parameter information for the sensing task, such as the sensing area or range, target type, or radar cross-section (RCS).
[0095] ② After receiving a sensing request, the BS / UE determines whether to use a variable pulse width (VPWM) transmission mode based on the sensing task information. When the BS / UE selects the VPWM transmission mode, it further needs to determine the resource configuration and signal configuration for using VPWM based on the sensing task information. The resource configuration includes the time domain start position, frequency domain start position, time domain repetition period, number of time domain repetitions, and frequency domain bandwidth. The signal configuration for VPWM includes the number and width of the pulses.
[0096] ③ The BS / UE transmits variable pulse width signals to the target area;
[0097] ④ The BS / UE performs a transmit / receive handover to receive the variable pulse width signal reflected by the sensing target;
[0098] ⑤ The BS / UE performs signal processing on the received variable pulse width pulse signal to obtain sensing measurement information;
[0099] ⑥ The BS / UE will report the sensing measurement information to the SF.
[0100] In one embodiment, the reception and processing of variable pulse width (VPWM) signals are mainly described. Figure 9 is a schematic diagram of a sensing process based on VPWM signals provided in one embodiment. As shown in Figure 9, the transmitter first transmits a narrower pulse, then switches to receive mode to receive the narrower pulse, then switches back to transmit mode to transmit a wider pulse, and finally switches back to receive mode to receive the wider pulse. These two receptions yield two sensing results. The sensing result of the narrower pulse has a smaller blind zone, while the sensing result of the wider pulse has a higher signal-to-noise ratio (SNR). These two sensing results can be further combined into one sensing result. The combining method can be simple splicing, such as using part of the sensing result of the narrower pulse to supplement the blind zone of the wider pulse. The combining method can also be signal-level coherent combining, that is, combining the overlapping parts of the two results while retaining the non-overlapping parts of the two results. In coherent combining, maximum ratio combining (MRC) can be used to ensure that the SNR of the combined result is maximized.
