[0050] Next, the technical solutions in the embodiments of the present application will be clearly described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art belong to the scope of protection of the present application.

[0051] The terms "first", "second", etc. in the present application are used to distinguish similar objects, rather than to describe a specific order or sequence. It should be understood that such terms can be interchanged under appropriate circumstances so that the embodiments of the present application can be implemented in an order other than those illustrated or described herein, and the objects distinguished by "first" and "second" are usually of the same type, and the number of objects is not limited. For example, the first object can be one or multiple. In addition, "or" in the present application means at least one of the connected objects. For example, "A or B" covers three scenarios, namely, Scenario 1: including A and not including B; Scenario 2: including B and not including A; Scenario 3: including both A and B. The character " / " generally indicates an "or" relationship between the associated objects before and after.

[0052] It should be noted that the technology described in the embodiments of this application is not limited to Long Term Evolution (LTE) / LTE-Advanced (LTE-A) systems, and can also be used in other wireless communication systems, such as Code Division Multiple Access (CDMA), Time Division Multiple Access (TDMA), Frequency Division Multiple Access (FDMA), Orthogonal Frequency Division Multiple Access (OFDMA), Single-carrier Frequency Division Multiple Access (SC-FDMA), or other systems. The terms "system" and "network" in this application are often used interchangeably. The described technology can be used in the systems and radio technologies mentioned above, as well as in other systems and radio technologies. The following description describes the New Radio (NR) system for example purposes, and the NR term is used in most of the following descriptions, but these technologies can also be applied to systems other than NR system applications, such as the 6th Generation (6 th Generation, 6G) communication system.

[0053] To facilitate the understanding of the embodiments of this application, the following technical points are introduced first:

[0054] I. Regarding communication and sensing integration.

[0055] Future mobile communication systems, such as Beyond 5th Generation (B5G) mobile communication systems or 6th Generation (6G) mobile communication systems, will not only have communication capabilities but also sensing capabilities in the future. The sensing capability means that one or more devices with sensing capabilities can sense information such as the orientation, distance, and speed of a target object through the transmission and reception of wireless signals, or detect, track, identify, image, etc. a target object, event, or environment. In the future, with the deployment of small base stations with high-frequency band and large bandwidth capabilities such as millimeter waves and terahertz in the 6G network, the sensing resolution will be significantly improved compared to centimeter waves, enabling the 6G network to provide more refined sensing services. Typical sensing functions and application scenarios are shown in Table 1.

[0056]

[0057] Table 1: Typical sensing functions and application scenarios.

[0058] Communication-perception integration (abbreviated as communication-sensing integration) means that in the same system, through spectrum sharing and hardware sharing, the integrated design of communication and perception functions is realized. While the system is transmitting information, it can sense information such as direction, distance, and speed, detect, track, and identify target devices or events. The communication system and the perception system complement each other, achieving an improvement in overall performance and bringing a better service experience.

[0059] The integration of communication and radar belongs to a typical application of communication-perception integration (communication-sensing fusion). In the past, radar systems and communication systems were strictly separated due to different research objects and focuses of attention, and the two systems were studied independently in most scenarios. In fact, both radar and communication systems are typical ways of information transmission, acquisition, processing, and exchange, and there are many similarities in terms of working principles, system architectures, and frequency bands. The design of communication-radar integration has great feasibility, which is mainly reflected in the following aspects: First, both the communication system and the perception system are based on the electromagnetic wave theory, and use the transmission and reception of electromagnetic waves to complete information acquisition and transmission; Second, both the communication system and the perception system have structures such as antennas, transmitters, receivers, and signal processors, and there is a large overlap in hardware resources; With the development of technology, there is also more and more overlap in their working frequency bands; In addition, there are similarities in key technologies such as signal modulation, reception detection, and waveform design. The integration of communication and radar systems can bring many advantages, such as cost savings, size reduction, power consumption reduction, spectrum efficiency improvement, and mutual interference reduction, thus improving the overall performance of the system.

[0060] According to the different first signal sending nodes and receiving nodes, it is divided into 6 basic sensing methods, as Figure 1 shown, specifically including:

[0061] (1) Base station echo sensing. In this sensing method, base station A sends the first signal and performs sensing measurements by receiving the echo of the first signal.

[0062] (2) Air interface sensing between base stations. Base station B receives the first signal sent by base station A and performs sensing measurements.

[0063] (3) Uplink air interface sensing. Base station A receives the first signal sent by terminal A and performs sensing measurements.

[0064] (4) Downlink air interface sensing. Terminal B receives the first signal sent by base station B and performs sensing measurements.

[0065] (5) Terminal echo sensing. Terminal A sends the first signal and performs sensing measurements by receiving the echo of the first signal.

[0066] (6) Sidelink (SL) sensing between terminals. Terminal B receives the first signal sent by Terminal A and performs sensing measurements.

[0067] It should be noted that Figure 1 each sensing method in [reference document] takes a first signal sending node and a first signal receiving node as examples. In an actual system, one or more different sensing methods can be selected according to different sensing use cases and sensing requirements, and there can be one or more sending nodes and receiving nodes for each sensing method. Figure 1 The sensing targets in [reference document] take people and vehicles as examples, and it is assumed that neither people nor vehicles carry or install signal receiving or sending devices. The sensing targets in the actual scenario are more diverse.

[0068] The first signal in this article includes at least one of a reference signal, a synchronization signal, a data signal, and a dedicated signal. Sensing services can be supported by receiving or sending the first signal. For example, sensing measurement quantities or sensing results can be obtained by receiving or sending the first signal. The sensing result refers to the result that meets the sensing requirements. For example: the shape of the sensing target, 2D or 3D environment reconstruction, spatial position, orientation, displacement, moving speed, acceleration; speed measurement, distance measurement, angle measurement or imaging of the target object in radar-like sensing; the presence or absence of people or objects; the actions, gestures, breathing frequency, heart rate, sleep quality, etc. of the sensing target such as people.

[0069] Optionally, the first signal in this application may be a signal that does not contain transmission information, such as existing Long Term Evolution (LTE) or New Radio (NR) synchronization and reference signals, including Synchronization Signal and PBCH block (SSB) signals, Channel State Information-Reference Signal (CSI-RS), Demodulation Reference Signal (DMRS), Sounding Reference Signal (SRS), Positioning Reference Signal (PRS), Phase Tracking Reference Signal (PTRS), etc.; it may also be a single-frequency continuous wave (CW), frequency-modulated continuous wave (FMCW), and ultra-wideband Gaussian pulse commonly used in radar; it may also be a newly designed dedicated signal with good correlation characteristics and low peak-to-average power ratio, or a newly designed integrated communication and sensing signal that not only carries certain information but also has good sensing performance. For example, the new signal is formed by splicing, combining, or superimposing at least one dedicated first signal or reference signal and at least one communication signal in the time domain or frequency domain.

[0070] The Sensing Function network element in this application, which can also be called the sensing network element or sensing function, can be on the Radio Access Network (RAN) side or the core network side. That is, it can be a network node in the core network or RAN responsible for at least one function such as sensing request processing, sensing resource scheduling, sensing information interaction, and sensing data processing. For example, it can be upgraded based on the Access and Mobility Management Function (AMF) or Location Management Function (LMF) in the 5G network, or it can be other network nodes or newly defined network nodes. Specifically, the functional characteristics of the Sensing Function network element may include at least one of the following:

[0072] (2) Determine the sensing method to be used based on factors such as the type of sensing service, information of the sensing service consumer, required sensing Quality of Service (QoS) requirement information, sensing capabilities of the wireless signal transmitting device, sensing capabilities of the wireless signal measuring device, etc. The sensing method can include: base station A transmits and base station B receives, or base station transmits and terminal receives, or base station A transmits and receives by itself, or terminal transmits and base station receives, or terminal transmits and receives by itself, or terminal A transmits and terminal B receives, etc.

[0073] (3) Determine the sensing device for the sensing service based on factors such as the type of sensing service, information of the sensing service consumer, required sensing QoS requirement information, sensing capabilities of the wireless signal transmitting device, sensing capabilities of the wireless signal measuring device, etc., where the sensing device includes a wireless signal transmitting device or a wireless signal measuring device.

[0074] (4) Manage the overall coordination and scheduling of resources required for the sensing service, such as performing corresponding configuration of the sensing resources of the base station or terminal;

[0075] (5) Perform data processing on the value of the sensing measurement quantity, or perform calculations to obtain the sensing result. Further, verify the sensing result, estimate the sensing accuracy, etc.

[0076] The terminal in this application can be a mobile phone, a tablet personal computer, a laptop computer or a notebook computer, a personal digital assistant (PDA), a handheld computer, a netbook, an ultra-mobile personal computer (UMPC), a mobile internet device (MID), an augmented reality (AR) or virtual reality (VR) device, a robot, a wearable device, a vehicle-mounted device (VUE), a pedestrian terminal (PUE), a smart home (home devices with wireless communication functions, such as refrigerators, TVs, washing machines or furniture, etc.), a game console, a personal computer (PC), a teller machine or a self-service machine, etc. Terminal-side devices. Wearable devices include: smart watches, smart bracelets, smart earphones, smart glasses, smart jewelry (smart bracelets, smart bracelets, smart rings, smart necklaces, smart anklets, smart ankle chains, etc.), smart wristbands, smart clothing, game consoles, etc. It should be noted that the specific type of the terminal is not limited in the embodiments of this application.

[0078] II. Introduction to four-step random access

[0079] The basic process of contention-based four-step random access (taking Synchronization Signal and PBCH block (SSB) as an example) is shown in Figure 2 :

[0080] Step 1: The terminal (e.g., User Equipment (UE)) determines the Physical Random Access Channel (PRACH) occasion associated with the SSB index based on an SSB index whose measured Synchronisation signal-reference signal received quality (SS-RSRP) of the target cell is greater than the RSRP preset threshold (rsrp-ThreholdSSB), specifically the next available PRACH occasion corresponding to the PRACH occasion of the SSB; the RSRP preset threshold is notified by the base station to the UE.

[0081] In Step 1, the UE selects a preamble index, for example, the UE randomly selects a preamble index.

[0082] Step 2: The UE sends Message 1 (MSG 1) to the base station according to the PRACH occasion and preamble index determined in the first step.

[0083] Among them, before the UE sends MSG 1, it needs to determine the target receiving power of MSG 1, so as to determine the transmission power of MSG 1.

[0084] Step 3: After receiving MSG 1, the base station sends Message 2 (MSG 2) to the UE;

[0085] Optionally, the base station calculates the Timing Advance (TA) of the UE according to the received preamble and sends the TA to the user through MSG2 (for the UE to use when sending Message 3 (MSG3)). In addition, MSG2 also includes time-frequency resource allocation information for scheduling MSG3, power control information, etc.

[0086] Optionally, MSG2 includes the preamble index detected by the base station, TA command, Temporary Cell-Radio Network Temporary Identifier (TC-RNTI), and uplink grant, where the uplink grant is used to indicate the time-frequency resource allocation information and power control information for scheduling MSG3;

[0087] Optionally, after the UE sends a preamble, it will listen for the Physical Downlink Control Channel (PDCCH) within the Random Access Response (RAR) window to receive the RAR corresponding to the Random Access - Radio Network Temporary Identifier (RA-RNTI). If the RAR replied by the base station is not received within the RAR time window, this random access procedure is considered to have failed.

[0088] Optionally, when the UE successfully receives an RAR and the preamble index carried in the RAR is the same as the preamble index sent by the UE, it is considered that the RAR has been successfully received, and at this time the UE can stop listening for the RAR.

[0089] Step 4: The UE receives MSG2 and sends MSG 3 to the base station according to the indication of MSG2 (TA, resource allocation information, power control information, etc.).

[0090] Optionally, MSG3 includes an identifier for conflict resolution, which can be a user identifier or a user flag from the core network. Specifically:

[0091] 1) For a UE in the Radio Resource Control Connected state (RRC_CONNECTED), its unique identifier is the C-RNTI.

[0092] 2) For a UE in the Radio Resource Control Idle state (RRC_IDLE), a unique UE identifier from the core network will be used: 39-bit ng-5G-S-TMSI-Part1 or a 39-bit random number as its identifier. At this time, the base station needs to communicate with the core network first to respond to Msg3.

[0093] 3) For a UE in the Radio Resource Control Inactive state (RRC_INACTIVE), a unique UE identifier from the core network will be used: 24-bit resumeIdentity (ShortI-RNTI-Value) or 40-bit resumeIndetity (I-RNTI-Value) as the identifier for restoring the UE context.

[0094] Step 5: The base station receives MSG 3 and sends Message 4 (MSG 4) to the UE.

[0095] Optionally, the base station sends MSG4 scrambled with the user identifier in MSG3 to the UE.

[0096] Optionally, if the scrambling identifier of MSG4 received by the UE matches the user identifier in MSG3, the random access process is completed.

[0097] Random access process event trigger scenarios:

[0098] 1) Initial access: The UE transitions from the RRC_IDLE state to the RRC_CONNETTED state;

[0099] 2) RRC connection reestablishment: To enable the UE to reestablish a radio connection after a radio link failure (during reestablishment, the cell may or may not be the cell where the UE's radio link failed);

[0100] 3) Handover: The UE is in the RRC_CONNETTED state, and at this time, the UE needs to establish uplink synchronization with a new cell;

[0101] 4) When uplink or downlink data arrives in the RRC_CONNETTED state and the UE's uplink is out of synchronization at this time;

[0102] 5) When uplink data arrives in the RRC_CONNETTED state and the UE does not have Physical Uplink Control Channel (PUCCH) resources for Scheduling Request (SR);

[0103] 6) SR failure: Reacquire PUCCH resources through the random access process;

[0104] 7) Request during RRC synchronous reconfiguration;

[0105] 8) Access in the RRC_INACTIVE state: The UE transitions from the RRC_INACTIVE state to the RRC_CONNETTED state;

[0106] 9) Establish time alignment when adding a Secondary Cell (SCell);

[0107] 10) Request other System Information (SI): When the UE is in the RRC_IDLE state and the RRC_CONNETTED state, request other SI through the random access process;

[0108] 11) Beam failure recovery: When the UE detects a failure and discovers a new beam, it will select the new beam.

[0109] Therefore, the random access process has two different modes:

[0110] Mode 1: Contention-based random access procedure: Applied to the above 2), 3), 4), 5), 6), 8), 10) or 11).

[0111] Mode 2: Non-contention-based random access procedure: Applied to the above 3), 4), 7), 9), 10) or 11).

[0112] For the contention-based random access procedure, the UE can only initiate it on the PCell, while for the non-contention-based random access procedure, the UE can initiate it either on the primary cell (PCell) or on the SCell.

[0113] III. Introduction to two-step random access.

[0114] Two-step RACH is an enhancement of four-step RACH, see Figure 3 .

[0115] Among them, the message A (MSGA) of two-step RACH includes the preamble sent on the PRACH channel (i.e., MSG1 in four-step RACH) and the payload sent on the PUSCH channel (i.e., MSG3 in four-step RACH); there is a time interval between the preamble and the physical uplink shared channel (PUSCH);

[0116] Optionally, different from the transmission resource of MSG3 in four-step RACH which is indicated by MSG2, the transmission resource of MSGAPUSCH in two-step RACH adopts a part of the periodically reserved time-frequency resource.

[0117] Optionally, there is an association relationship between the PRACH and the PUSCH, so that the UE can determine the corresponding PUSCH after determining the PRACH.

[0118] Optionally, if the UE selects a preamble without a corresponding PUSCH occasion (PO), the UE only sends the preamble (equivalent to falling back to four-step RACH).

[0119] Optionally, when the base station detects MSGA, it will feedback message B (MSGB), and MSGB is carried by the PDCCH and the physical downlink shared channel (PDSCH); among them, the PDCCH is scrambled by the MSGB-RNTI, and the MSGB-RNTI is determined by the time-frequency position where the RACH occasion (RO) transmitted by the PRACH is located; the value range of the MSGB-RNTI is different from the value range of the RA-RNTI;

[0120] Optionally, when the MSGA sent by the UE is successfully detected and the MSGB fed back by the base station contains the user's SuccessRAR, the UE feeds back a Hybrid Automatic Repeat Qequest-ACKnowledgemen (HARQ-ACK) message indicating successful reception of MSGB, marking the successful completion of the random access procedure by the UE.

[0121] Optionally, after the UE sends MSGA, if the UE does not correctly receive the MSGB RAR corresponding to its preamble within the detection window, the UE needs to retransmit MSGA and increase the transmission power.

[0122] Optionally, when the number of retransmissions of MSGA in two-step RACH reaches the target threshold, it falls back to four-step RACH, that is, the UE sends MSG1.

[0123] In addition, when the base station can correctly detect the preamble of MSGA but the PUSCH message demodulation fails, the base station can feed back a FallbackRAR, similar to MSG2 in four-step RACH, to schedule the transmission of the UE's MSG3; if the transmission of MSG3 fails and retransmission occurs at this time, two-step RACH needs to be preferentially used for the retransmission of MSGA. (That is, it falls back to four-step RACH, but the preamble is no longer sent because it was successfully sent during two-step RACH).

[0124] Optionally, the time-frequency resources of two-step RACH are configured independently, or two-step RACH and four-step RACH share RO resources, which are distinguished by different preamble sequence sets.

[0125] Application scenarios: Two-step RACH has a shorter total delay, less signaling overhead and power consumption compared to four-step RACH, and is suitable for scenarios such as unlicensed spectrum and small packet transmission.

[0126] Among them, the timing relationship between the PRACH channel and the PUSCH channel of MSGA is as Figure 4 shown, that is, within the PRACH configuration period, there is a time offset between the PRACH slot and the PUSCH slot, and there is a corresponding relationship between PO (PUSCH occasion) and RO (RACH Occasion), that is, the PO associated with it can be determined according to RO.

[0127] Definition of PO: The PUSCH occasion for PUSCH transmission is defined by a set of frequency resources, time resources, etc.

[0128] Optionally, each PO can also carry multiple Demodulation Reference Signal (DMRS) resources, with a maximum of 8 DMRS resources multiplexed per PO.

[0129] IV. Association between the Preamble of RO and the DMRS of PO in Two-step RACH:

[0130] After the UE selects a certain RO and a certain preamble index of the RO, through a predefined mapping rule, it finds the corresponding PO for transmitting PUSCH and the DMRS resources. Figure 5 A mapping example is given, where the abscissa of the left schematic diagram represents the increasing order of time index, and the ordinate represents the increasing order of frequency index.

[0131] Next, in conjunction with the accompanying drawings, the perception processing method, device, communication equipment, and readable storage medium provided by the embodiments of the present application will be described in detail through some embodiments and their application scenarios.

[0132] See Figure 6 An embodiment of the present application provides a perception processing method, which is applied to a terminal, and the specific steps are 601.

[0133] Step 601: The terminal measures one or more first signals to obtain measurement values of the target metrics of the one or more first signals;

[0134] Among them, the target metrics include at least one of the following: a first metric, a second metric, and a third metric. The first metric is related to the received power, the second metric is related to the interference and noise power, and the third metric is related to both the received power and the interference and noise power;

[0135] Among them, the target metrics include at least one of the following (1) to (3):

[0136] (1) A first metric;

[0137] The first metric is the linear average (in watts) of the received power of the perception target associated path in the channel response measured for the target signal on the resource unit carrying the target signal;

[0138] (2) A second metric;

[0139] The second indicator includes at least one of the following (2a) to (2c):

[0140] (2a) The fourth indicator;

[0141] The fourth indicator is the sum of the linear average of the power of the paths other than the perceived target associated path in the channel response of the target signal on the target resource and the linear average of the interference and noise power of the signals other than the target signal on the first resource (in watts), where the first resource is the target resource or other resources other than the target resource; the target resource includes the resource unit carrying the first signal, and the resource unit can be a time-domain resource unit or a frequency-domain resource unit;

[0142] Optionally, the fourth indicator = total received power - the first indicator; where the total received power can be expressed as: the linear average of the total received power on the target resource (including the received power of the signals of the serving cell and non-serving cells, adjacent channel interference, and thermal noise, etc.) (in watts); or, the total received power = RSSI * K1, where K1 is a coefficient, and the measurement resource of RSSI is the target resource or other resources (such as the resources configured by high-layer signaling).

[0143] (2b) The fifth indicator;

[0144] The fifth indicator is the linear average of the interference and noise power of the signals other than the target signal on the second resource, where the second resource is the target resource or other resources other than the target resource;

[0145] Optionally, the fifth indicator = total received power - the received power of the first signal; where the received power of the first signal is the reference signal receiving power (RSRP) of the first signal.

[0146] (2c) The sixth indicator;

[0147] The sixth indicator is the linear average of the power of the paths other than the perceived target associated path in the channel response of the target signal on the target resource (in watts);

[0148] Optionally, the fourth indicator = RSRP of the first signal - the first indicator;

[0149] (3) The third indicator;

[0150] The third indicator includes at least one of the following (3a) to (3d):

[0151] (3a) The seventh indicator;

[0152] The seventh indicator represents the first indicator divided by the fourth indicator, i.e., seventh indicator = first indicator / fourth indicator;

[0153] (3b) The eighth indicator;

[0154] The eighth indicator represents the first indicator divided by the fifth indicator, i.e., eighth indicator = first indicator / fifth indicator;

[0155] (3c) The ninth indicator;

[0156] The ninth indicator represents the first indicator divided by the sixth indicator, i.e., ninth indicator = first indicator / sixth indicator;

[0157] (3d) The tenth indicator;

[0158] The tenth indicator represents the first indicator divided by the first received power and then multiplied by a preset first coefficient. The first received power represents the total received power on the target resource, or the first received power represents the product of the Received Signal Strength Indication (RSSI) and a preset second coefficient. The measurement resource of the RSSI is the target resource or other resources, i.e., tenth indicator = K2 * first indicator / total received power, where K2 is a coefficient.

[0159] In an implementation manner of the present application, the obtaining method of the perceived target associated path includes:

[0160] The terminal performs channel estimation on the target signal and the received signal corresponding to the target signal to obtain a channel response;

[0161] The terminal transforms the channel response to the first dimension;

[0162] The terminal determines the perceived target associated path among the paths corresponding to the first dimension;

[0163] Wherein, the first dimension includes at least one of the following: delay dimension; Doppler dimension; azimuth angle dimension; elevation angle dimension.

[0164] In an implementation manner of the present application, when the terminal determines the perceived target associated path among the paths corresponding to the first dimension, it includes:

[0165] The terminal selects the path that meets the first condition as the perceived target associated path among the paths corresponding to the first dimension;

[0166] Wherein, the first condition includes at least one of the following:

[0167] 1) The first parameter of the path is greater than or equal to the first threshold or within the first interval range;

[0168] 2) The difference between the diameter and the first parameter of the first arrival diameter or the reference diameter is greater than or equal to the second threshold or lies within the second interval range;

[0169] 3) The second parameter of the diameter satisfies a preset modulation rule;

[0170] Wherein, the first parameter includes at least one of the following: amplitude, power, intensity, energy, Doppler, time delay, angle;

[0171] The second parameter includes at least one of the following: amplitude, power, intensity, energy, phase.

[0172] In an implementation manner of the present application, when the terminal selects, from the diameters corresponding to the first dimension, the diameters that meet the second condition as the perception target associated diameters, it includes:

[0173] The terminal determines a first diameter set from the diameters corresponding to the first dimension. The third parameter of each diameter in the first diameter set is greater than or equal to the third threshold. The third parameter includes at least one of the following: amplitude, power, intensity, energy;

[0174] The terminal determines, from the first diameter set, the diameters that meet the first condition as the perception target associated diameters.

[0175] In an implementation manner of the present application, the calculation method of the first index is as follows:

[0176] The terminal performs channel estimation on the basis of the transmitted first signal (hereinafter represented by X(k)) and the received signal corresponding to the first signal (hereinafter represented by Y(k)) to obtain the channel response (Channel Response), that is, H(k) = Y(k) / X(k), where k = 0, 1, 2,..., K - 1 represents the resource unit index. After the terminal obtains the channel response H(k), it transforms it into the first dimension and determines the perception target associated diameters in the first dimension. Then, the power of the perception target associated diameters is calculated as the first index. If the perception target associated diameters include multiple diameters, the sum of the powers of the multiple diameters is calculated as the first index.

[0177] Wherein, the first dimension includes at least one of the following: time delay dimension; Doppler dimension; azimuth angle dimension; elevation angle dimension. For example, time delay - Doppler dimension, time delay - Doppler - angle dimension, etc.;

[0178] For example, if \(H(f)\) is the channel response, where \(f = 0, 1, 2, \ldots, N - 1\) represents the frequency-domain sampling points (e.g., subcarrier indices), then by performing the inverse Fourier transform on \(H(f)\), it can be transformed into the delay dimension (the first dimension); for another example, if \(H(f, t)\) is the channel response, where \(f = 0, 1, 2, \ldots, N - 1\) represents the frequency-domain sampling points (e.g., subcarrier indices) and \(t = 0, 1, 2, \ldots, M - 1\) represents the time-domain sampling points (e.g., OFDM symbol indices), then by performing the inverse Fourier transform along the frequency domain dimension and the Fourier transform along the time domain dimension on \(H(f, t)\), it can be transformed into the delay-Doppler dimension (the first dimension); for another example, if \(H(f, t, s)\) is the channel response, where \(f = 0, 1, 2, \ldots, N - 1\) represents the frequency-domain sampling points (e.g., subcarrier indices), \(t = 0, 1, 2, \ldots, M - 1\) represents the time-domain sampling points (e.g., Orthogonal Frequency Division Multiplexing (OFDM) symbol indices), and \(s = 0, 1, 2, \ldots, P - 1\) represents the spatial domain sampling points (antenna indices or port indices), then by performing the inverse Fourier transform along the frequency domain dimension, the Fourier transform along the time domain dimension, and the Fourier transform along the antenna domain dimension on \(H(f, t, s)\), it can be transformed into the delay-Doppler-angle dimension (the first dimension).

[0179] In this application, a method for determining the paths associated with the sensing target (simply referred to as sensing paths) in the channel response measured for the first signal:

[0180] Step 1: Determine the first path set. The paths in the first path set include the paths among all the paths whose amplitude, power, intensity, or energy exceeds a preset threshold after the channel response is transformed into the first dimension. (For example Figure 10 in which, paths 0, 1, 2, 3 are the paths in the first path set);

[0181] Optionally, the preset threshold can be set to be higher than the noise threshold or higher than the noise interference threshold.

[0182] It can be understood that the step of determining the first path set is optional, and the paths associated with the sensing target can also be determined only according to Step 2.

[0183] Step 2: Select the paths that meet the first condition from the first path set or from all the paths as the paths associated with the sensing target.

[0184] Optionally, the first condition includes at least one of the following:

[0185] 1) The amplitude, power, intensity, or energy of the path exceeds a preset threshold or is within a preset interval range; for example, the preset threshold is 5 times higher than the noise threshold;

[0186] 2) The Doppler of the path exceeds a preset threshold or lies within a preset range;

[0187] 3) The time delay of the path exceeds a preset threshold or lies within a preset range;

[0188] 4) The angle of the path exceeds a preset threshold or lies within a preset range;

[0189] 5) The difference in amplitude or power or intensity or energy between the path and the first-arrival path (e.g., Line-of-Sight (LOS) path) or the reference path (e.g., the signal path reflected by a known target (such as a Reconfigurable Intelligence Surface (RIS) or Backscatter or other known passive target, etc.)) exceeds a preset threshold or lies within a preset range;

[0190] 6) The Doppler difference between the path and the first-arrival path (e.g., LOS path) or the reference path (e.g., the signal path reflected by a known target (such as RIS or Backscatter device or other known passive target, etc.)) exceeds a preset threshold or lies within a preset range;

[0191] 7) The time delay difference between the path and the first-arrival path (e.g., LOS path) or the reference path (e.g., the signal path reflected by a known target (such as RIS or Backscatter device or other known passive target, etc.)) exceeds a preset threshold or lies within a preset range;

[0192] 8) The angle difference between the path and the first-arrival path (e.g., LOS path) or the reference path (e.g., the signal path reflected by a known target (such as RIS or Backscatter device or other known passive target, etc.)) exceeds a preset threshold or lies within a preset range;

[0193] 9) The amplitude or power / intensity / energy or phase of the path satisfies a specific modulation rule, and the specific modulation rule is the modulation rule of a Tag or a backscatter device or an RIS, that is, the path associated with the sensed target can be the path modulated and reflected by a Tag or a backscatter device or an RIS.

[0194] It should be noted that the first condition of each of the above items can also be based on the results of statistics over a period of time; for example, the proportion of the above indicators (such as the Doppler of the path, the time delay of the path, etc.) exceeding the preset threshold or lying within the preset range reaches a preset proportion within a preset time window, or the number of times the above indicators (such as the Doppler of the path, the time delay of the path, etc.) exceed the preset threshold or lie within the preset range reaches a preset number within the preset time window;

[0195] Among them, the preset threshold or the set range is sent by other devices to the receiving device, and is determined by other devices according to the prior perception information or the perception requirements. Alternatively, the preset threshold or the set range is determined by the receiving device according to the prior perception information or the perception requirements.

[0196] Among them, the prior perception information or the perception requirements include the following information:

[0197] 1) Perception service or perception service type;

[0198] Optionally, the perception service may include, but is not limited to, at least one of the following: detecting whether a target exists, positioning, speed detection, distance detection, angle detection, acceleration detection, material analysis, component analysis, shape detection, category classification, radar cross section radar cross section detection, polarization scattering characteristic detection, fall detection, intrusion detection, quantity statistics, indoor positioning, gesture recognition, lip reading recognition, gait recognition, expression recognition, face recognition, breathing monitoring, heart rate monitoring, pulse monitoring, humidity or brightness or temperature or atmospheric pressure monitoring, air quality monitoring, weather condition monitoring, environment reconstruction, terrain and landform, building or vegetation distribution detection, pedestrian or vehicle flow detection, crowd density, vehicle density detection, etc.; The perception service type may classify multiple different perception services according to certain characteristics. For example, it can be classified into detection type perception services (such as intrusion detection, fall detection), parameter estimation type perception services (distance, angle, speed calculation), recognition type perception services (action recognition, identity recognition), etc. according to function, or it can also be classified according to the perception range (close range perception, medium range perception, long range perception), according to the perception fineness (coarse-grained perception, fine-grained perception, etc.), according to power consumption or energy consumption, according to resource occupancy, etc. If the perception service is breathing monitoring, the corresponding normal breathing frequency can be judged according to the gender and age of a person (for example, male: 13 - 21 times per minute, female: 15 - 20 times per minute; adult: 12 - 20 times per minute, child: about 30 - 40 times per minute), which can be used as prior perception information;

[0199] 2) Perception target area;

[0200] Optionally, the perception target area includes the position area of the perception object, or the position area that needs to be imaged or reconstructed; for example, the preset interval range of the time delay of the perception target association path is determined according to the approximate position or distance of the perception object.

[0201] 3) Perception object type;

[0202] Optionally, the perception objects are classified according to the possible motion characteristics of the perception objects, and each perception object type contains information such as the motion speed range, motion acceleration range, and typical RCS range of typical perception objects.

[0203] 4) Number of perceived targets;

[0204] Optionally, as a kind of perception prior information, the camera perception result can be used to obtain the number of perceived targets;

[0205] For example, Figure 10 The medium diameters 0, 1, 2, 3 are the diameters in the first diameter set, where the diameters 2, 3 are the perceived diameters that meet the first condition (for example, their time delays meet the preset threshold), and the diameters 0, 1 are the diameters associated with other scatterers. Figure 10 The horizontal axis in the middle is the first dimension, and the vertical axis is the normalized amplitude or power or intensity or energy.

[0206] For frequency range 1, the reference point of the first metric can be the antenna connector of a receiving device such as a terminal. For frequency range 1, if the receiving device has multiple receiving channels, the first metric measured and reported by the receiving device cannot be lower than the metric of any single receiving channel. For frequency range 2, the first metric measured by a certain receiving channel needs to be obtained by measuring the combined signals on multiple antenna elements corresponding to this receiving channel.

[0207] In another embodiment of the present application, the calculation method of the first metric is as follows:

[0208] Optionally, when calculating the received power of the perceived target associated diameter, it can also be the difference between the power of the perceived target associated diameter in the first dimension and as the first metric, where N 1 represents the number of diameters associated with the perceived target. is the average power of multiple diameters outside the first diameter set in the first dimension.

[0209] In one embodiment of the present application, the calculation method of the received power of the first signal is as follows:

[0210] The received power of the first signal can be that after the receiving device obtains the channel response H(k), it transforms it into the first dimension, determines the first diameter set in the first dimension, and then calculates the sum of the powers of all diameters in the first diameter set.

[0211] In another embodiment of the present application, the calculation method of the received power of the first signal is as follows:

[0212] The received power of the first signal can also be the difference between the sum of the powers of all diameters in the first diameter set in the first dimension and where N2 Indicates the number of paths in the first set of paths.

[0213] Calculation method of the total received power:

[0214] Total received power

[0215] In an implementation manner of the present application, the calculation method of the third indicator:

[0216] The channel response H(k) is subjected to a first filtering process to obtain H filter1 (k), and then based on H filter1 (k) and the first signal X(k), the received signal Y filter1 (k) after the first filtering process is calculated, that is, Y filter1 (k) = H filter1 (k)X(k). Then the received signal Y(k) is subtracted from the received signal Y filter1 (k) after the first filtering process to obtain the interference and noise signal Y σ1 (k), that is, Y σ1 (k) = Y(k) - Y filter1 (k), and then the third indicator is calculated

[0217] Wherein, the first filtering process is used to eliminate the noise and interference in the first dimension and the paths not associated with the perceived target. For example, the first filtering process sets Figure 10 the amplitude or power or intensity or energy of the paths other than the paths associated with the perceived target in to zero. The channel response H filter1 (k) after the first filtering process does not contain noise and interference and the paths not associated with the perceived target, and only contains the paths associated with the perceived target.

[0218] In an implementation manner of the present application, the calculation method of the fourth indicator is as follows:

[0219] The channel response H(k) is subjected to a second filtering process to obtain H filter2 (k), and then based on H filter2 (k) and the first signal X(k), the received signal Y filter2 (k) after the second filtering process is calculated, that is, Y filter2 (k) = H filter2 (k)X(k). Then the received signal Y(k) is subtracted from the received signal Y filter2 (k) after the second filtering process to obtain the interference and noise signal Y σ2 (k), that is, Y σ2 (k) = Y(k) - Y filter2 (k), and then the fourth indicator is calculated

[0220] The second filtering process may be a noise interference suppression process in the first dimension (for example Figure 10 setting the amplitude or power or intensity or energy of other paths except the first path set to zero), or a Minimum Mean Square Error (MMSE) filter. The channel response H filter2 after the second filtering process does not contain noise and interference, and only contains the paths in the first path set.

[0221] In another embodiment of the present application, the calculation method of the fourth index is as follows:

[0222] Calculate the fourth index P according to the average power of multiple paths outside the first path set in the first dimension σ2 , that is where N represents the number of sampling points in the first dimension.

[0223] If the receiving device determines multiple sensing targets, or the receiving device obtains the number of sensing targets according to sensing prior information or sensing requirements, there are the following several methods:

[0224] Method 1: Calculate the target index of each sensing target respectively. For example, in Figure 10 determine the paths associated with each sensing target respectively, and then calculate the respective target indexes corresponding to each sensing target; when calculating the third index corresponding to a certain sensing target (such as sensing target A) at this time, there are two methods: that is: the third index of sensing target A = total received power - the first index of sensing target A; or, the third index of sensing target A = total received power - the first index of sensing target A - the first index of sensing target B; (assuming there are two sensing targets in total: A and B); similarly, there are also two calculation methods for the fifth index: the fifth index of sensing target A = RSRP of the first signal - the first index of sensing target A; or, the fifth index of sensing target A = RSRP of the first signal - the first index of sensing target A - the first index of sensing target B; (assuming there are two sensing targets in total: A and B).

[0225] Method 2: Calculate a target index for multiple sensing targets. For example, in Figure 10 determine the paths associated with any sensing target, and then use these paths as the paths associated with the sensing target; it is equivalent to regarding multiple sensing targets as a virtual sensing target, and then calculating the target index corresponding to this virtual sensing target.

[0226] It can be understood that when step 601 is executed, the terminal is in the Idele state or the Inactive state, that is, the terminal can participate in the sensing service without accessing the connected state, reducing the energy consumption of the terminal.

[0227] In the embodiments of the present application, the terminal or the network side device can determine whether the terminal is suitable to participate in the sensing service according to the measured values of the target indicators of one or more first signals, and the terminal or the network side device can select a suitable terminal to participate in the sensing service according to the measured values of the target indicators of one or more first signals to ensure the performance of sensing.

[0228] In the embodiments of the present application, before the terminal measures one or more first signals to obtain the measured values of the target indicators of the one or more first signals, the method further includes:

[0229] The terminal receives the first information sent by the network side device, and the first information includes the target indicators of the first signals that the terminal needs to measure.

[0230] Optionally, after receiving the first information, the terminal can determine whether to measure the first signal.

[0231] For example, if the location information of the terminal is consistent with the sensing target area in the sensing requirement carried by the first information, the terminal determines to measure the first signal.

[0232] For another example, if the type of the sensing service supported by the terminal is consistent with the type of the sensing service in the sensing requirement in the first information, the terminal determines to measure the first signal.

[0233] For another example, if the terminal finds that it meets the time information of the sensing service in the first information (the terminal can participate in sensing during this time period), the terminal determines to measure the first signal.

[0234] In an embodiment of the present application, if the number of the multiple first signals is N, the terminal measures the multiple first signals, including:

[0235] The terminal measures the first signals through different receiving beams.

[0236] For example, at different times, different receiving beams are used to measure the first signal; at this time, the base station needs to send the same first signal at the different times (that is, the beam direction of the first signal sent by the base station at the different times remains unchanged).

[0237] Optionally, the first signal includes at least one of the following: a dedicated signal for sensing, a sounding reference signal, a preamble, a channel state information-reference signal (CSI-RS), a tracking reference signal (TRS), and a synchronization signal.

[0238] Optionally, the bandwidth of the dedicated signal for sensing, CSI-RS, or TRS can be configured to be wider than that of the synchronization signal, and the signal is quasi co-located (QCL) with the synchronization signal. For example, the synchronization signal includes multiple beams, and each beam is associated with a first signal.

[0239] In an embodiment of the present application, the method further includes:

[0240] The terminal determines whether the measured value of the target metric of the one or more first signals satisfies a second condition;

[0241] If the measured value of the target metric of at least some of the one or more first signals satisfies the second condition, the terminal reports the identifier of the at least some first signals to the network-side device;

[0242] Or,

[0243] If the measured value of the target metric of the one or more first signals does not satisfy the second condition, the terminal does not initiate a random access procedure, or the terminal initiates a random access procedure and reports to the network-side device through Message 1 or Message 3 or Message A that the measured value of the target metric of the first signal does not satisfy the second condition, or the terminal does not participate in the sensing service;

[0244] Wherein, the second condition includes at least one of the following:

[0245] 1) The measured value of the target metric is greater than or equal to a fourth threshold;

[0246] 2) The measured value of the target metric is less than or equal to a fifth threshold;

[0247] 3) The measured value of the target metric is within a third interval range;

[0248] 4) The proportion of the measured value of the target metric that is greater than or less than a sixth threshold within a first time window is greater than or equal to a first proportion;

[0249] 5) The proportion of the measured value of the target metric that is within a fourth interval range within a second time window is greater than or equal to a second proportion;

[0250] 6) The number of times that the measured value of the target metric is greater than or less than the seventh threshold within the third time window is greater than or equal to the first number;

[0251] 7) The number of times that the measured value of the target metric is within the fifth interval range within the fourth time window is greater than or equal to the second number.

[0252] Optionally, the second condition may be notified by the network - side device to the UE through a paging message, SIB, or other signaling.

[0253] In an embodiment of the present application, the random access occasion resources in the sensing - related random access procedure are different from the random access occasion resources in the communication - related random access procedure.

[0254] In an embodiment of the present application, if the measured values of the target metrics of at least some of the one or more first signals satisfy the second condition, the terminal initiates a sensing - related random access procedure, including:

[0255] If the measured values of the target metrics of at least some of the one or more first signals satisfy the second condition, and the communication link performance of the at least some first signals satisfies the communication condition, the terminal reports the identifiers of the at least some first signals to the network - side device.

[0256] In an embodiment of the present application, the terminal reporting the identifiers of the at least some first signals to the network - side device includes:

[0257] The terminal reports the identifiers of the at least some first signals to the network - side device through Message 1, Message 3, or Message A.

[0258] For example, if the terminal measures 10 first signals, and the measured values of the target metrics of 6 of the first signals satisfy the second condition, the terminal reports the identifiers of the 6 first signals to the network - side device through Message 1, Message 3, or Message A.

[0259] In an embodiment of the present application, the measured values of the target metrics of the first signals associated with Message 1 or Message A do not satisfy the second condition; that is, the terminal first measures the first signals or SSB, determines the first signals or SSB that satisfy the communication metrics (for example, RSRP is greater than a certain threshold), and then sends Message 1 or Message A through the paging occasion (PO) corresponding to the first signals or SSB that satisfy the communication metrics.

[0415] The implementation manners of the present application are introduced below in conjunction with specific embodiments.

[0416] Embodiment 1

[0417] See Figure 8 , and the specific steps include:

[0418] Step 801: The sensing function sends sensing requirements to the base station;

[0419] Step 802: The base station receives the sensing capabilities or sensing subscription information reported by the terminal;

[0420] Step 803: The base station sends first information to the UE according to at least one of the sensing requirements, sensing capabilities, and sensing subscription information;

[0421] Optionally, the sensing capabilities include the types of sensing services supported by the UE or the sensing modes supported by the UE.

[0422] Optionally, the sensing subscription information may include, but is not limited to, whether the UE supports downlink-based sensing in the idle state or the inactive state.

[0423] Among them, the UE is in the idle state or the inactive state.

[0424] Optionally, the first information includes at least one of the following: sensed requirements, configuration information of the first signal, time information of the sensed service, sensing mode (e.g., uplink sensing or downlink sensing).

[0425] Step 804: The UE determines whether to measure the first signal according to the first information;

[0426] For example, if the location information of the UE (which can be the location information obtained by the UE through downlink positioning) is consistent with the sensed target area in the sensed requirements carried by the first information, the UE determines to measure the first signal; for another example, if the type of the sensed service supported by the UE is consistent with the type of the sensed service in the sensed requirements in the first information, the UE determines to measure the first signal; for still another example, if the UE finds that it meets the time information of the sensed service in the first message (during this time period, the UE can participate in sensing), the UE determines to measure the first signal.

[0427] Step 805: The base station sends the first signal to the UE;

[0428] Step 806: The UE measures one or more first signals to obtain measurement values of target metrics of the one or more first signals;

[0429] Step 807: The UE determines whether the measurement values of the target metrics of the one or more first signals meet the second condition;

[0430] Optionally, the second condition is notified by the base station to the UE through a paging message, SIB, or other signaling.

[0431] Step 808: If the measurement values of the target metrics of at least some of the one or more first signals meet the second condition, the UE sends the measurement values of the target metrics of the at least some first signals to the base station through Msg1, Msg3, or MsgA;

[0432] It can be understood that if the terminal determines that the measurement values of the target metrics of the one or more first signals do not meet the second condition, the terminal does not send Msg1, Msg3, or MsgA.

[0433] In one implementation, the UE reports to the base station, through Msg1, Msg3, or MsgA, the indexes of one or more first signals whose measurement values of the target metrics meet the preset conditions. For example, the UE reports, through PUSCH in Msg3 or MsgA, the index of the first signal whose measurement value of the target metric meets the second condition.

[0434] In another implementation, the transmission parameters (e.g., the transmission parameters include time domain resources, frequency domain resources, and preamble sequence format, etc.) of the preamble of Msg1 or MsgA sent by the terminal are associated with the index of the first signal.

[0435] In this embodiment, if the UE initiates a random access procedure due to communication requirements (for example, there is uplink data to be transmitted), the UE sends a preamble related to communication; for simplicity of design, the RO resources related to sensing and the RO resources related to communication can be independent.

[0436] Step 809: The base station determines that the UE meets the requirements of service sensing;

[0437] Step 810: The base station sends the information related to sensing to the UE through Msg2 or Msg4 or MsgB;

[0438] Optionally, the information related to sensing includes, but is not limited to, the configuration information of the second signal, the format information of the measurement quantity that the UE needs to feedback, etc., where the second signal can be the same as or different from the first signal.

[0439] Step 811: Transmit the data related to sensing on the PUSCH resource scheduled by the configured grant configured in the RRC inactive state or on the PUSCH resource of MSG A.

[0440] In this embodiment, after the base station receives MSG1 or MSGA sent by the UE, it determines that the UE meets the requirements of the sensing service, and subsequently can instruct the UE to officially participate in sensing. For example, the UE can transmit the data related to sensing, such as sensing measurement quantities, on the Msg3 PUSCH in the four-step random access procedure, or on the Msg A PUSCH in the two-step random access procedure, or on the PUSCH resource scheduled by the configured grant configured in the RRC inactive state. The base station can transmit the information related to sensing through MSG2, MSG4 or MSG B, etc.

[0441] Embodiment 2

[0442] See Figure 9 , and the specific steps include:

[0443] Step 901: The sensing function sends the sensing requirements to the base station;

[0444] Step 902: The base station sends the first information to the UE;

[0445] Step 903: The UE determines whether to measure the first signal according to the first information;

[0446] Step 904: The base station sends the first signal to the UE;

[0447] Step 905: The UE measures one or more first signals and obtains the measured values of the target indicators of one or more first signals;

[0448] Step 906: The UE sends the measurement value of the target metric of one or more first signals to the base station via Msg1 or MsgA;

[0449] Step 907: The base station determines whether the measurement value of the target metric of one or more first signals meets the third condition. If it meets the condition, the base station selects the UE to participate in the sensing service (perform Step 908); otherwise, the base station does not select the UE to participate in the sensing service;

[0450] Optionally, the third condition may be notified to the base station by the sensing function or determined by the base station according to the sensing requirements.

[0451] Step 908: The base station sends sensing-related information to the UE via Msg2 or Msg4 or MsgB;

[0452] Step 909: Transmit sensing-related data on the PUSCH resource scheduled by the configured grant configured in the RRC inactive state or on the PUSCH resource of MSG A.

[0453] In one implementation, the UE reports the measurement value of the target metric to the base station via MSG 1, and the base station determines whether to select the UE; if the UE is selected, the base station transmits sensing-related information via MSG2 or MSG4, etc., such as the configuration information of the second signal that the UE needs to measure, the format information of the measurement quantity that the UE needs to feedback, etc. The UE can transmit sensing-related data, such as sensing measurement quantities, on the Msg3 PUSCH during the four-step random access procedure or on the PUSCH resource scheduled by the configured grant configured in the RRC inactive state.
