Description

Technical Field

[0001] This invention generally relates to communication-sensing integrated (ISAC) systems, and more specifically, to signal design and sequence configuration within ISAC systems. Background Technology

[0002] Unless otherwise stated, the methods described in this section are not considered prior art in the claims, nor are they considered prior art by virtue of their inclusion in this section.

[0003] With the development of ISAC in certain network systems (e.g., 5G, B5G, and 6G networks), integrating radar sensing into wireless networks has become increasingly important. Achieving robust and reliable radar sensing under practical deployment constraints has become crucial.

[0004] However, full-duplex sensing architectures can be affected by residual self-interference, which may mask weak long-range echoes, while orthogonal frequency division multiplexing (OFDM)-based sensing may experience inter-symbol interference. Although pulse-based radar can avoid these problems, it may introduce a minimum detection range, and partially received echoes may generate increased sidelobes, thus degrading detection performance. Furthermore, mutual interference between sensing signals from different cells or base stations and receiver saturation further limit overall sensing capabilities.

[0005] Therefore, improving signal design and configuration mechanisms is increasingly important to support reliable sensing in ISAC systems. Thus, enhanced signal design and configuration techniques are still needed to improve the sensing reliability of ISAC systems. Summary of the Invention

[0038] This invention discloses detailed embodiments and implementations of the claimed subject matter. However, it should be understood that the inventive embodiments and implementations are merely illustrative of the claimed subject matter, which can be implemented in various forms. Moreover, the invention can be implemented in many different forms and should not be construed as limited to the exemplary embodiments and implementations set forth herein. Rather, these exemplary embodiments and implementations are provided to make the specification of this invention comprehensive and complete, and to fully convey the scope of the invention to those skilled in the art. In the following description, details of known features and techniques may be omitted to avoid unnecessarily obscuring the presented embodiments and implementations.

[0039] Overview Embodiments of the present invention relate to various techniques, methods, schemes, and / or solutions for signal design and sequence configuration in ISAC systems associated with devices in mobile communications. According to the present invention, multiple possible solutions can be implemented individually or in combination. That is, although these possible solutions are described individually below, two or more of them can be implemented in some combination.

[0040] In certain network scenarios, devices (such as user equipment (UE) or network nodes) can function as both transmitters (TX) and receivers (RX) to transmit and receive signals in a single-site sensing network environment to sense targets and communicate with other network nodes. In some network scenarios, the device acting as a TX (e.g., UE or network node) and the device acting as an RX (e.g., UE or network node) can exchange necessary network parameters. In a single-site sensing network scenario, the TX device can transmit signals for sensing targets and communicating with other network nodes, while the RX device can receive signals reflected from the sensed targets.

[0041] It should be noted that the following description is for illustrative purposes only and may focus on a single-site sensing network scenario. However, this is not intended to limit the invention. Those skilled in the art will understand that the invention can also be applied to other sensing configurations, such as single-site sensing network scenarios.

[0042] In some embodiments of the present invention, an apparatus operating as TX and RX (e.g., a base station (BS) or UE) may transmit one or more sensing signals for sensing purposes. The one or more sensing signals may include a first sensing signal. The first sensing signal may include: (1) a first sequence transmitted at a first power, and (2) a second sequence transmitted at a second power. The first power may be higher than the second power. The apparatus may receive one or more reflections corresponding to the one or more sensing signals.

[0043] Therefore, by transmitting different sequences at different power levels, the sensing performance for both distant and near-range targets can be enhanced. Specifically, a higher-power sequence (i.e., the first sequence) can improve the detection capability for distant targets, while a lower-power sequence (i.e., the second sequence) can reduce receiver saturation and achieve reliable detection of near-range targets. Such a sensing configuration can also further mitigate self-interference effects and improve overall sensing reliability.

[0044] In some embodiments, the apparatus may transmit multiple sensing signals. Each sensing signal may include a first sequence. The first sequence may include: (1) a first portion of the first sequence, and (2) a second portion of the first sequence. The first sequence of sensing signals may form a first complementary sequence set. The first portion and the second portion of the first sequence may be configured to suppress sidelobes of a portion of the received signal.

[0045] Therefore, since the first sequence of the sensed signal can form a first complementary sequence set, and each first sequence can contain different parts for partial signal processing, the side lobes generated during the correlation processing (including side lobes caused by partial received signals) can be effectively suppressed, thereby improving detection reliability and distance performance.

[0046] Figure 1 This is an example scenario 100 according to an embodiment of the present invention. Scenario 100 involves network nodes and targets, which may be part of a wireless communication network (e.g., an LTE network, a 5G / NR network, an Internet of Things (IoT) network, or a 6G network).

[0047] Scenario 100 illustrates an example network framework. Network nodes can communicate with other devices. In the figures of this application, the network node is exemplified by a BS (Base Station) to illustrate a single-site sensing network scenario. In some cases, the BS can function as a single-site radar, transmitting specially designed sensing signals via full-duplex radio and receiving corresponding reflected signals from targets. However, this example is not limiting. Those skilled in the art will understand that network nodes can also be implemented as other devices (e.g., UEs) and can collaborate with other devices in a single-site sensing network scenario.

[0048] In some embodiments, the network node can operate as both TX and RX. The network node can transmit one or more sensing signals for sensing purposes. The one or more sensing signals may include a first sensing signal. The first sensing signal may have a sequence pattern of transmitting different sequences at different power levels.

[0049] Specifically, the first sensing signal may include: (1) a first sequence transmitted at a first power, and (2) a second sequence transmitted at a second power. The first power may be higher than the second power. In some cases, the first power may be configured for long-range detection. More specifically, the first power may be set to ensure sufficient transmission energy for detecting weak echoes from distant targets. In some cases, the second power may be configured to be less than the analog-to-digital converter (ADC) saturation power to prevent receiver saturation when receiving echoes from nearby targets. Subsequently, the network node may receive one or more reflections corresponding to the one or more sensing signals. The reflections may be from at least one target during the reception window.

[0050] Figure 2 This is an example scenario 200 according to an embodiment of the present invention. In some implementations, the first sensing signal may include a first sequence and a second sequence. The first sequence may be transmitted at a first power. The second sequence may be transmitted at a second power.

[0051] Specifically, the transmission of the sensing signal can be divided into multiple cycles, including a high-power component cycle T. h High-low transition period T t Low power level component period T l and the silent period T s During the high-power-level component period, the first sequence can be transmitted at a high power level. During the low-power-level component period, the second sequence can be transmitted at a low power level. In some cases, the duration of the corresponding period can be adjusted. In some cases, the two power levels can be configured.

[0052] In some cases, the high-power stage component period can be used to detect distant targets at a high power level configured according to sensing requirements. In other cases, the low-power stage can be configured below the ADC saturation stage (e.g., the ADC saturation power stage at the ADC input). In some cases, the high-low transition period can be very short or omitted (i.e., no high-low transition period), while the silence period can be extended to allow for the reception of target echoes.

[0053] In some cases, the receive window during the transmission of the sensed signal may include a sampling off period corresponding to the transmission of the first sequence and a sampling on period associated with the transmission of the second sequence. In some cases, during the sampling off period, the network node does not sample the input signal due to ADC saturation, and therefore the network node is in transmit-only mode. In other cases, during the sampling off period, the network node may sample the input signal, but these sampled values ​​are discarded.

[0054] In some cases, the length of the sampling off period can be the same as the length of the high-power stage period. In some cases, during the sampling on period, the network node can sample the input signal because the low-power stage does not cause ADC saturation, allowing for close-range detection within the blind zone created by the sampling off period. In some cases, the length of the sampling on period can be equal to the sum of the high-low transition period, the low-power stage period, and the silence period. In some cases, the silence period can be zero.

[0055] In some implementations, one or more sensing signals may include a second sensing signal. The second sensing signal may include: (1) a third sequence transmitted via a first power, and (2) a fourth sequence transmitted via a second power. The first sensing signal and the second sensing signal may be grouped based on correlation attributes.

[0056] More specifically, the first sequence and the third sequence can be complementary sequences, and the second sequence and the fourth sequence can be complementary sequences.

[0057] Figure 3 This is an example scenario 300 according to an embodiment of the present invention. In some implementations, the first sensing signal and the second sensing signal can be grouped into a signal group based on the correlation attributes contained in the signals. The sensing signals within a group can be used jointly for radar sensing at network nodes.

[0058] In some cases, in the first sensing signal, the first sequence (i.e., sequence A) can be transmitted at a high power level, and the second sequence (i.e., sequence C) can be transmitted at a low power level. In the second sensing signal, the third sequence (i.e., sequence B) can be transmitted at a high power level, and the fourth sequence (i.e., sequence D) can be transmitted at a low power level.

[0059] In these cases, sequences A and B can be configured as complementary sequences (or approximately complementary sequences) of the same length. Sequences C and D can be configured as complementary sequences (or approximately complementary sequences) of the same length. .

[0060] More specifically, complementary sequences can satisfy the following equation: in Indicates time The correlation function between time series 'X' and 'Y'.

[0061] In addition to the complementary sequence requirements between A and B, and between C and D, additional correlation constraints can be imposed between sequences A, B, C, and D. When these complementarity and correlation conditions are met, the range sidelobes in the overall correlation result can be eliminated when jointly processing the two sensing signals.

[0062] In some implementations, one or more sensing signals may include a third sensing signal and a fourth sensing signal. The third sensing signal may include: (1) a fifth sequence transmitted via a first power, and (2) a sixth sequence transmitted via a second power. The fourth sensing signal may include: (1) a seventh sequence transmitted via the first power, and (2) an eighth sequence transmitted via the second power. The first, second, third, and fourth sensing signals may be grouped based on correlation attributes.

[0063] More specifically, the first and third sequences can be complementary sequences. In some cases, the second and fourth sequences can be complementary sequences. The fifth sequence can be the same as the first sequence. The seventh sequence can be the same as the third sequence. The sixth sequence and the second sequence can be opposite sequences. The eighth sequence and the fourth sequence can be opposite sequences. In some cases, the fifth sequence and the first sequence can be opposite sequences. The seventh sequence and the third sequence can be opposite sequences. The sixth sequence can be the same as the second sequence. The eighth sequence can be the same as the fourth sequence.

[0064] Figure 4 This is an example scenario 400 according to an embodiment of the present invention. In some implementations, the first sensing signal, the second sensing signal, the third sensing signal, and the fourth sensing signal can be grouped as a signal group based on the correlation attributes contained in the signals. The sensing signals within a group can be used jointly for radar sensing at network nodes.

[0065] In some cases, in the first sensing signal, the first sequence (i.e., sequence A) can be transmitted at a high power level, and the second sequence (i.e., sequence C) can be transmitted at a low power level. In the second sensing signal, the third sequence (i.e., sequence B) can be transmitted at a high power level, and the fourth sequence (i.e., sequence D) can be transmitted at a low power level.

[0066] In some cases, in the third sensing signal, the fifth sequence (i.e., the same as sequence A) can be transmitted at a high power level, and the sixth sequence (i.e., sequence C') can be transmitted at a low power level. In the fourth sensing signal, the seventh sequence (i.e., the same as sequence B) can be transmitted at a high power level, and the eighth sequence (i.e., sequence D') can be transmitted at a low power level.

[0067] In these cases, sequences A and C can be configured as complementary sequences (or approximately complementary sequences) of equal length. Sequences B and D can be configured as complementary sequences (or approximately complementary sequences) of equal length. Sequence C and sequence C' can be configured as reverse sequences. Sequence D and sequence D' can be configured as reverse sequences.

[0068] More specifically, complementary sequences can satisfy the following equation: in Indicates time The correlation function between time series 'X' and 'Y'.

[0069] In some cases, when the high-low transition period is set to zero, the overall correlation function... This can be analyzed in two parts. First, when hour, Secondly, when hour, Therefore, even if the transition period from high to low is not zero, the overall correlation function can remain without sidelobes.

[0070] In some implementations, the one or more sensing signals may be transmitted within at least one sensing symbol. Figure 5A and Figure 5B These are example scenarios 500A and 500B according to embodiments of the present invention. Specifically, within a sensing symbol, one or more sensing signals can be arranged in various configurations. In scenario 500A, each sensing symbol may include a single sensing signal. In this case, multiple sensing symbols can be processed jointly to achieve a sidelobe-free correlation result. In scenario 500B, each sensing symbol may include multiple sensing signals. The required number of sensing symbols may depend on the number of sensing signals contained in each sensing symbol, the group of sensing signals used, and other sensing requirements.

[0071] In some implementations, at least one sensing symbol may be integrated into the transmit-receive (TX-RX) transition period. Figure 6A and Figure 6B These are example scenarios 600A and 600B according to embodiments of the present invention. Specifically, in a 4G network, when a network node switches from downlink (DL) to uplink (UL), there may be special frames with guard intervals, while in a 5G network, flexible symbols may be required during the transmit-receive (TX-RX) transition period. In scenario 600A, a sensing symbol may be deployed between at least one TX symbol and at least one RX symbol. In scenario 600B, a sensing symbol may be deployed between at least one TX symbol and at least one RX symbol.

[0072] Figure 7A and Figure 7B These are example scenarios 700A and 700B according to embodiments of the present invention. In some implementations, communication cycles and sensing cycles may alternate on the timeline of network nodes, regardless of how many symbols are included in the communication cycle and sensing cycle.

[0073] Specifically, TX and RX symbols can constitute a communication cycle. Sensing symbols can constitute a sensing cycle. In some cases, the communication cycle can be longer than the sensing cycle. In scenario 700A, sensing cycles can be deployed periodically along the timeline with fixed sensing intervals. In scenario 700B, sensing cycles can be deployed non-periodically along the timeline. Both scenarios can be processed to obtain sensing estimates.

[0074] Network nodes can process received signals during the sensing cycle. The sensed signals to be jointly processed can first be sampled, and then a matched filter (or mismatch filter) is applied to obtain the corresponding aperiodic correlation results. The matched filter outputs of different sensed signals can then undergo Doppler processing, for example, by applying a Fast Fourier Transform (FFT) algorithm. Constant False Alarm Rate (CFAR) detection can then be performed on the resulting delay-Doppler (RD) map to estimate the target's distance and velocity.

[0075] In certain scenarios, pulse radar systems may experience partial reception of the sensed echo. More specifically, such as... Figure 8 As shown, the TX of the pulse radar can be divided into two periods, including: (1) the pulse transmission period T h and (2) the silent period T s The pulse transmission period may include the duration of the radar pulse signal and the recovery time required for the system to switch from transmit mode to receive mode.

[0076] During the pulse transmission period, the TX can transmit a high-power continuous wave signal generated based on pulse shaping, OFDM architecture, or other applicable generation methods. The methods for generating continuous wave pulse signals from a sequence are not limited to those described above. The RX of a pulse radar can operate under two different conditions, depending on whether sampling occurs during the transmission of the continuous wave pulse signal.

[0077] In some cases, when the RX samples the radar echo from a target within the minimum range while the TX transmits a continuous wave pulse signal, the radar echo may include distorted signals due to ADC saturation and a portion of the received signal. During radar sensing processing, the distorted signal can be discarded. However, the portion of the received signal may still affect sensing operations. Therefore, strong targets within the minimum range may interfere with the detection of targets outside the minimum range. Furthermore, when the portion of the received signal is used to detect targets within the minimum range, its longer autocorrelation sidelobes may degrade multi-target detection performance.

[0078] In some cases, when the radar cross-section (RX) is switched off during continuous wave pulse signal transmission, the radar echo from targets within minimum range contains only a portion of the received signal. The impact of this scenario is similar to that described above. Therefore, improved sequence configurations can be introduced to suppress sidelobes caused by the partial received signal.

[0079] In some embodiments, a network node may transmit multiple sensing signals. Each sensing signal may include a first sequence. The first sequence may include: (1) a first portion of the first sequence, and (2) a second portion of the first sequence. The first sequence of sensing signals may form a first complementary sequence set. The first and second portions of the first sequence may be configured to suppress sidelobes of a portion of the received signal. Subsequently, the network node may receive one or more reflections corresponding to the sensing signals. The reflections may be caused by at least one target during the reception window.

[0080] Figure 9 This is an example scenario 900 according to an embodiment of the present invention. In some implementations, a sequence set (SS) Can contain A length of The sequence. This set of sequences can be denoted as... -SS, and available The matrix is ​​represented as: in Represents a sequence set The OK. Represents a sequence The first part (e.g., the first to the second part) (point), and Represents a sequence The second part (e.g., the first) arrive (Point). To suppress sidelobes of the received signal, network nodes can transmit sensing signals in groups, with each sensing signal represented as a pulse. Specifically, A sensing signal (i.e., a pulse) (or (Integer multiples of sensing signals) can be transmitted within a coherent processing interval, so that... Individual sensing signal sequences can be processed as a group during coherent processing.

[0081] like Figure 9 As shown, a set of sensing signals may contain A sensing signal (i.e., a pulse). Each transmission of a sensing signal (i.e., each pulse) may include a transmission period T. h and the silent period T s During the transmission phase, network nodes can send continuous signals generated from a sequence for sensing purposes, where the first... The sensing signal (i.e. the first) Each pulse can correspond to a transmission sequence. .

[0082] In some cases, the SS sent The following equations can be satisfied: in, Represents a sequence The nonperiodic autocorrelation function. Represents a sequence and In time The relevant functions. Then It can be a set of complementary sequences (CSS), denoted as ( )-CSS.

[0083] In some cases, sequences subsequence of The first part and subsequence The second part satisfies the following equation: in, Representation and sequence The corresponding portion of the received signal represents the sequence that the network node can sample. Part of it. Representation and sequence The corresponding portion of the received signal. Sequence and Each has Possible scenarios, ranging from a single receiving point in the sequence to the sequence's... A continuous receiving point.

[0084] In some cases, by jointly processing the sensed signal groups, some received signals from targets within the minimum range may not affect the detection of targets outside the minimum range. Specifically, sidelobes associated with targets within the minimum range can be suppressed, keeping them below a certain value. Within the range index.

[0085] In some implementations, multiple sensing signals may include two sensing signals. Figure 10A and Figure 10B These are example scenarios 1000A and 1000B according to embodiments of the present invention. Specifically, the sequence of sensed signals may need to be transmitted in groups. Network nodes can transmit two sequences as a paired set.

[0086] In scenario 1000A, the sensing signal group may include a first sensing signal and a second sensing signal transmitted in a paired manner. The transmission of each sensing signal can be divided into a transmission period T. h and the silent period T s The first sensing signal may include a first sequence. . first sequence It can include two sequence parts of equal length, namely the first part of the sequence (i.e., the sequence itself). ) and the second part of the sequence (i.e., the sequence The second sensing signal may include a sequence. .sequence It can include two sequence parts of equal length, namely the first part of the sequence (i.e., the sequence itself). ) and the second part of the sequence (i.e., the sequence In some cases, sequences and sequence They can be the same sequence. In some cases, the sequence... It can be a sequence The phase-reversed version (i.e. - ).

[0087] In scenario 1000B, the sensing signal group may include a first sensing signal and a second sensing signal transmitted in a paired manner. The transmission of each sensing signal may be divided into a transmission period and a silence period. The first sensing signal may include a first sequence. . first sequence It can include two sequence parts of equal length, namely the first part of the sequence (i.e., the sequence itself). ) and the second part of the sequence (i.e., the sequence The second sensing signal may include a sequence. .sequence It can include two sequence parts of equal length, namely the first part of the sequence (i.e., the sequence itself). ) and the second part of the sequence (i.e., the sequence In some cases, sequences and sequence They can be the same sequence. In some cases, the sequence... It can be a sequence The phase-reversed version (i.e. - ).

[0088] In some cases, sequences and sequence (or sequence) and sequence They can form a pair of complementary sequences of the same length. Therefore, the sequence and sequence Sending (or sequence) and pulse sequence The transmissions can form a pair of complementary sequences. This configuration ensures that the sequences maintain their complementary properties. Complementary sequences satisfy the following equation: in Indicates time The correlation function between the sequences 'X' and 'Y'.

[0089] For the sensing signal group in scenario 1000A, when the target delay Less than At that time, a portion of the received signal from the sensing signal group can be phase-reversed and represented as and (Right now ).when When this condition is met, the following equation can be satisfied: This can show that for targets within the minimum distance range (i.e., when...) (At that time), the sidelobe length generated by the related processing can be .sequence It can have length This can reduce the sidelobe range of the corresponding correlation function to Therefore, sidelobes can be generated after the target delay. Complete elimination at the point. When the target is delayed. At that time, part of the received signal of the sensing signal group can be represented as and .when When this condition is met, the following equation can be satisfied: This indicates that targets within the minimum distance range pass through... No sidelobes appear after the time delay, indicating that some received signals will not affect the detection of targets outside the minimum range. When the target is delayed... At that time, the complete signal information of the transmitted waveform can be fully acquired. The following equation can be satisfied: In scenario 1000B, the sensing signal group can exhibit the same correlation characteristics as the sensing signal group in scenario 1000A. This sequence configuration ensures that during correlation processing, sidelobes associated with targets within minimum distance do not extend beyond the correlation point H, and the length of the sidelobes can be reduced to half the sequence length.

[0090] In some implementations, each sensed signal may include a first sequence and a second sequence. Specifically, the first sequence may be transmitted at a first power, and the second sequence may be transmitted at a second power. The first power is higher than the second power. In some cases, the first power may be configured for long-range detection. More specifically, the first power may be set to ensure sufficient transmission energy for weak echoes from distant targets. In some cases, the second power may be configured to be less than the ADC saturation power to prevent receiver saturation when receiving echoes from nearby targets.

[0091] In some implementations, each second sequence may include: (1) a first portion of the second sequence, and (2) a second portion of the second sequence. The second sequences of the sensed signal may form a second complementary sequence set. The first and second portions of the second sequence may be configured to suppress sidelobes of a portion of the received signal.

[0092] Figure 11 This is an example scenario 1100 according to an embodiment of the present invention. In some implementations, to suppress sidelobes of some received signals, the sensing signals can be transmitted in groups. Specifically, A sensing signal (or (Integer multiples of sensing signals) can be transmitted within a coherent processing interval, such that during coherent processing, Individual sensing signals appear as a group.

[0093] In some cases, from sequence sets The generated sensing signals can be transmitted at high power levels, where each signal is of length 1. The sequence can be represented as A matrix, denoted as: in, express The row sequence. Represents a sequence The first part (e.g., the first to the second part) (point), and Represents a sequence The second part (e.g., the first) arrive point).

[0094] In some cases, from sequence sets The generated sensing signals can be transmitted at low power levels, where each signal is of length 1. The sequence can be represented as A matrix, denoted as: in, express The row sequence. Represents a sequence The first part (e.g., the first to the second part) (point), and Represents a sequence The second part (e.g., the first) arrive (Point). To suppress sidelobes of the minimum-range target, a sequence set is sent. and sequence set The following equations can be satisfied: in, Representation and sequence The corresponding portion of the received signal represents the sequence that the network node can sample. Part of it. Representation and sequence The corresponding part receives the signal.

[0095] During sensing operations using a portion of the received signal corresponding to the low-power signal, the sequence set It can satisfy the sequence set The same mathematical constraints apply. When these conditions are met, joint processing of the sensing signal group can reduce the sidelobes of some received signals to half the sequence length.

[0096] In some implementations, the plurality of sensing signals may include four sensing signals. Figure 12This is an example scenario 1200 according to an embodiment of the present invention. Specifically, the sequence of sensed signals may require transmission in groups.

[0097] In scenario 1200, the sensing signal group may include a first sensing signal, a second sensing signal, a third sensing signal, and a fourth sensing signal. In the first sensing signal, the sequence transmitted at a high power level may include a first portion of the sequence (i.e., the sequence...). ) and the second part of the sequence (i.e., the sequence The sequence transmitted at low power levels may include the first part of the sequence (i.e., the sequence number). ) and the second part of the sequence (i.e., the sequence In some cases, sequences Can be used with sequence They are complementary. In some cases, sequences Can be used with sequence They complement each other.

[0098] In the second sensing signal, the sequence transmitted at the high power level may include a first part of the sequence (i.e., the sequence). ) and the second part of the sequence (i.e., the sequence The sequence transmitted at low power levels may include the first part of the sequence (i.e., the sequence number). ) and the second part of the sequence (i.e., the sequence ).

[0099] In some cases, sequences Can be used with sequence Same, and sequence Can be a sequence The inverse version. In some cases, the sequence Can be a sequence The inverse version, and the sequence Can be used with sequence same.

[0100] In some cases, sequences Can be used with sequence Same, and sequence Can be a sequence The inverse version. In some cases, the sequence Can be a sequence The inverse version, and the sequence Can be used with sequence same.

[0101] In the third sensing signal, the sequence transmitted at a high power level may include a first part of the sequence (i.e., the sequence). ) and the second part of the sequence (i.e., the sequence A sequence transmitted at a low power level may include the first part of the sequence (i.e., the sequence...). ) and the second part of the sequence (i.e., the sequence ).

[0102] In some cases, sequences It can be a sequence The phase-reversed version, sequence It can be a sequence A phase-reversed version.

[0103] In the fourth sensing signal, the sequence transmitted at a high power level may include the first part of the sequence (i.e., the sequence). ) and the second part of the sequence (i.e., the sequence A sequence transmitted at a low power level may include the first part of the sequence (i.e., the sequence...). ) and the second part of the sequence (sequence) ).

[0104] In some cases, sequences It can be a sequence The phase-reversed version, sequence It can be a sequence A phase-reversed version. When the sequence and sequence Form a complementary set, and the sequence and sequence When another complementary set is formed, the sequence configuration requirements for eliminating some of the sidelobes of the received signal can be fully met.

[0105] In some implementations, the first complementary sequence set and the second complementary sequence set of the first sequence of the sensed signal can be orthogonal to each other. Specifically, the second complementary sequence set can be formed from sequences of other sensed signals, which can be transmitted by network nodes or other devices.

[0106] More specifically, to suppress signal interference between and within cells, the sensing signal groups corresponding to different cells can be configured using mutually orthogonal complementary sequence sets. Each cell can be associated with the same network node or different devices.

[0107] Figure 13 This is an example scenario 1300 according to an embodiment of the present invention. In some implementations, the SS may include... A length of A sequence of . Such a set can be represented as ( )-SS, and can be used Matrix representation. Let Represents a group Matrix, each matrix having a size of ,as follows: in express The Row sequence.

This configuration can be called an orthogonal sensing signal group. To achieve sidelobe cancellation of some received signals, the sequence... ( (Also need to meet) Figure 9 The sequence configuration requirements are shown in the diagram and described in the relevant paragraphs.

[0109] In some implementations, the first complementary sequence set and the third complementary sequence set of the first sequence of the sensed signal can be orthogonal to each other, and the second complementary sequence set and the fourth complementary sequence set of the second sequence of the sensed signal can be orthogonal to each other. Specifically, the third complementary sequence set and the fourth complementary sequence set are formed by sequences of other sensed signals, which can be transmitted by network nodes or other devices.

[0110] More specifically, to suppress signal interference between and within cells, the sensing signal groups corresponding to different cells can be configured using mutually orthogonal complementary sequence sets. Each cell can be associated with the same network node or different devices.

[0111] Figure 14 This is an example scenario 1400 according to an embodiment of the present invention.

To achieve sidelobe cancellation of some received signals, the sequence... and sequence ( (Also need to meet) Figure 11 The sequence configuration requirements are shown in the diagram and described in the relevant paragraphs.

[0113] Figure 15A and Figure 15B These are example scenarios 1500A and 1500B according to embodiments of the present invention. In some implementations, in a single-base station scenario 1500A, mutually orthogonal pulse or sensing signal groups can be used in different sectors (e.g., cells) of a network node (e.g., a base station) to mitigate mutual interference between sensing signals within a cell. In a multi-base station scenario 1500B, the base stations can adopt the same configuration as the network node (e.g., a single base station) to ensure orthogonality between adjacent sectors and suppress interference between sensing signals from different sectors. Therefore, the network configuration may require at least three sets of orthogonal pulse or sensing signal groups to support normal operation.

[0114] In some cases, the network configuration associated with mutually orthogonal pulse or sensing signal groups can be determined by the central network node and distributed to each base station. In other cases, the network configuration can be determined by a single base station and sent to other base stations.

[0115] In some implementations, the network node of the present invention may include a transceiver. The transceiver of the network node may receive one or more reflections corresponding to one or more sensing signals (such as the sensing signals described above in the present invention). The one or more sensing signals may include a first sensing signal. The first sensing signal may include: (1) a first sequence transmitted at a first power, and (2) a second sequence transmitted at a second power. The first power is higher than the second power.

[0116] In some implementations, the transceiver may include a receiver. The receiver may include an antenna module, a low-noise amplifier (LNA) module, an ADC module, and a gain control module. The gain control module may be configured to control the gain of the LNA. In some cases, the gain control module may be configured to decrease the gain of the LNA during the transmission of a first sequence and increase the gain of the LNA during the transmission of a second sequence.

[0117] Figure 16 This is an example scenario 1600 according to an embodiment of the present invention. For example, the transceiver includes a baseband processing module, a transmitting module, and a receiving module. The baseband processing module is electrically connected to the transmitting module and the receiving module.

[0118] The transmitting module includes a digital-to-analog converter (DAC) module, a power amplifier (PA) module, and an antenna module. The receiving module includes an ADC module, an LNA module, an antenna module, and a gain control module. The gain control module is electrically connected to the LNA module and is configured to: (1) reduce the gain of the LNA during the transmission of the first sequence, and (2) increase the gain of the LNA during the transmission of the second sequence.

[0119] More specifically, the ADC module of the receiver module requires a recovery period after a saturation event. Therefore, the gain control module applies a lower gain during high-power transmission to prevent ADC saturation. This method ensures that the ADC remains in a non-recovery state during low-power transmission. During high-power transmission, the received signal exhibits strong self-interference and is therefore discarded during sensing processing. During low-power transmission, the gain control module applies a higher gain to reduce quantization noise in the echo signal.

[0120] In some implementations, the transceiver may include a receiver. The receiver may include an antenna module, an LNA module, an ADC module, and a switch located between the antenna module and the LNA module. In some cases, the switch may be configured to disconnect the antenna module from the LNA during the transmission of a first sequence and connect the antenna module to the LNA during the transmission of a second sequence.

[0121] Figure 17 This is an example scenario 1700 according to an embodiment of the present invention. For example, the transceiver includes a baseband processing module, a transmitting module, and a receiving module. The baseband processing module is electrically connected to the transmitting module and the receiving module.

[0122] The transmitting module includes a DAC module, a PA module, and an antenna module. The receiving module includes an ADC module, an LNA module, an antenna module, and a switch. The switch is located between the antenna module and the LNA module and is configured to: (1) disconnect the antenna module from the LNA during the transmission of the first sequence, and (2) connect the antenna module to the LNA during the transmission of the second sequence.

[0123] More specifically, during high-power transmission, the switch remains open to prevent ADC saturation due to self-interference. During low-power transmission, the switch closes, and automatic gain control (AGC) adjusts the receiver gain.

[0146] Additional notes The subject matter described in this invention sometimes illustrates different components included within or connected to other components. However, it should be understood that these depicted architectures are merely examples, and many other architectures implementing the same functionality can actually be implemented. Conceptually, any arrangement of components implementing the same function is effectively “associated” to enable the desired functionality. Therefore, regardless of architecture or intermediate components, any two components combined in this invention to achieve a specific function can be considered “associated” with each other to enable the desired functionality. Similarly, any two such associated components can also be considered “operationally connected” or “operationally coupled” to each other to achieve the desired functionality, and any two components that can be suchly associated can also be considered “operationally coupled” to each other to achieve the desired functionality. Specific examples of operationally coupled components include, but are not limited to, physically mating and / or physically interacting components and / or wirelessly interacting components and / or logically interacting and / or logically interactable components.

Those skilled in the art will also understand that if a specific number of claims is intentionally listed, this intention will be explicitly listed in the claims, and the absence of such a listing will not indicate this intention. For example, to aid understanding, the appended claims may include the use of the introductory phrases “at least one” and “one or more.” However, the use of such phrases should not be construed as implying that the introduction of the indefinite article “a” or “an” limits any particular claim that includes such an introductory claim to only one embodiment of such a listing, even when the same claim includes the introductory phrases “one or more” or “at least one” and indefinite articles such as “a” or “an,” for example, “a and / or one” should be interpreted as meaning “at least one” or “one or more,” the same applies to the use of definite articles used to introduce claims. Furthermore, even when a specific number of the introduced claims are explicitly listed, those skilled in the art will recognize that such a listing should be interpreted as meaning at least the number listed. For example, in the absence of other modifiers, the basic listing of "two listings" means at least two listings or two or more listings. Additionally, when using conventions such as "at least one of A, B, and C," it generally means, in the sense that those skilled in the art will understand, that a system having at least one of A, B, and C will include, but is not limited to, systems having A alone, having B alone, having C alone, having A and B together, having A and C together, having B and C together, and / or having A, B, and C together.
