[0035] The following will be combined with the drawings in the embodiments of the present disclosure to clearly and completely describe the technical solutions in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present disclosure.

[0036] Unless the context requires otherwise, throughout the specification and claims, the term "comprise" and other forms thereof, such as the third person singular form "comprises" and the present participle form "comprising", are to be interpreted as open, inclusive, that is, "including, but not limited to". In the description of the specification, the terms "one embodiment", "some embodiments", "exemplary embodiments", "example", "specific example" or "some examples" and the like are intended to indicate that specific features, structures, materials or characteristics associated with the embodiment or example are included in at least one embodiment or example of the present disclosure. The schematic representation of the above terms does not necessarily refer to the same embodiment or example. In addition, the specific features, structures, materials or characteristics may be included in any one or more embodiments or examples in any appropriate manner.

[0037] The terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the present disclosure, unless otherwise specified, "plurality" means two or more.

[0038] In the embodiments of the present disclosure, words such as "exemplary" or "for example" are used to indicate examples, illustrations, or descriptions. Any embodiment or design described as "exemplary" or "for example" in the embodiments of the present disclosure should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific way.

[0039] Additionally, the use of “based on” is meant to be open and inclusive, as a process, step, calculation, or other action “based on” one or more stated conditions or values ​​may, in practice, be based on additional conditions or values ​​beyond those stated.

[0040] At present, the discussion on the integration of interawareness in related technologies is mainly focused on the air interface, with less involvement of signaling interaction within the base station. There is no unified solution for how to deploy the perception function within the base station.

[0041] Therefore, the present disclosure provides a communication method, based on which a first unit of a wireless access network can receive perception configuration information from a second unit of a wireless access network, and the perception configuration information includes information required for the first unit of the wireless access network to perform a perception task. In this way, when the corresponding perception function is deployed inside a network device, signaling interaction between various wireless access network units during the perception process, that is, various signaling interactions inside the network device, can be realized. In this way, the application and development of the synaesthesia integration technology in network devices is facilitated.

[0042] Figure 1 FIG. 1 shows a schematic diagram of a synaesthesia integrated system structure provided by the present disclosure. The system integrates communication function and perception function. Figure 1 As shown, the system includes a network device and at least one terminal device. In some embodiments, the system may also include a sensing target.

[0043] In some embodiments, Figure 1 The synaesthesia integration system shown can be a third generation partnership project (3GPP) communication system, for example, a fourth generation (4G) long term evolution (LTE) system, a fifth generation (5G) new radio (NR) system, a vehicle to everything (V2X) system, a LTE and NR hybrid networking system, or a device-to-device (D2D) system, a machine-to-machine (M2M) communication system, an Internet of Things (IoT), and other next generation communication systems.

[0044] Among them, the network device can be a network-side device with wireless transceiver functions. For example, the network device can be a telepathic base station, which can also be called a base station. For example, it can be a base station, an evolved base station (evolvedNodeB, eNodeB), a next generation base station (next generation NodeB, gNB) in a 5G mobile communication system, a transmission reception point (transmission reception point, TRP), a base station that is subsequently evolved by 3GPP, an access node in a WiFi system, a wireless relay node, a wireless backhaul node, etc. In addition, the perception mode of the base station in the present disclosure can be a spontaneous and self-receiving mode or a collaborative perception mode. In the technical solution provided in the present disclosure, the network device can also be referred to as a first node.

[0045] In some embodiments, the internal logic architecture of the network device may include at least an open radio access network radio unit (O-RU), which may also be referred to as a first radio access network unit, an open radio access network distributed unit (O-DU), which may also be referred to as a second radio access network unit, an open radio access network centralized unit (O-CU), which may also be referred to as a third radio access network unit, an open base station unit (O-eNB), and a cloud component (O-Cloud), etc. Among them, the O-RU and the O-DU may be the main logic units related to the synaesthesia physical layer.

[0046] The O-RU is mainly involved in low physical layer functions, such as analog beamforming, analog-to-digital conversion, Fourier / inverse Fourier transform (FFT / IFFT), and addition / subtraction of cyclic prefix (CP). The O-DU is mainly involved in high physical layer functions, such as resource element mapping / demapping, addition / descrambling, channel estimation and equalization. In some embodiments, the O-DU and the O-RU are connected by wire through the front interface. The wired connection can be subdivided into the control plane, the user plane, the synchronization plane, and the management plane. Among them, the control plane is mainly responsible for transmitting semi-static control information, the user plane mainly transmits compressed frequency domain channel I / Q samples, the synchronization plane mainly transmits synchronization information between the O-DU and the O-RU, and the management plane mainly transmits static control information.

[0047] The sensing target may be any tangible object that can reflect electromagnetic waves, such as mountains, forests, or buildings, and may also include movable objects such as vehicles, drones, pedestrians, and terminal devices. The sensing target may also be referred to as a detected target, a sensed object, a detected object, or a sensed device, etc., and the present disclosure does not specifically limit this. In the technical solution provided in the present disclosure, the sensing target may also be referred to as a second node.

[0048] In this system, the network device can send downlink communication signals to the terminal device, and the terminal device can also send uplink communication signals to the network device. In addition, the network device can also send a sensing signal and receive an echo signal of the sensing signal reflected by the sensed target to estimate the speed, distance, angle, motion trajectory, shape and size of the sensed target. In some embodiments, the sensing process for the sensed target can be single-station sensing or multi-station sensing. Figure 2 As shown, similar to the multi-station collaboration in radar, multiple network devices can collaborate to realize the perception process of the perceived target.

[0049] Terminal equipment can refer to a user-side device with wireless transceiver functions. For example, a terminal is a handheld device with wireless communication functions (such as a mobile phone or tablet computer, etc.), a vehicle-mounted device, a wearable device, a terminal or computing device in an Internet of Things (IoT) system, etc. The terminal can also be called a terminal device or a user equipment (UE), without limitation.

[0050] In some embodiments, the network device may also be connected to the core network device wirelessly or wired. The core network device and the network device may be independent and different physical devices; or the functions of the core network device and the logical functions of the network device may be integrated on the same physical device; or the functions of part of the core network device and part of the network device may be integrated on the same physical device. In the technical solution provided in the present disclosure, the core network device may also be referred to as a third node.

[0051] It should be understood that Figure 1 This is just an exemplary architecture diagram. Figure 1 There is no limit to the number of devices or nodes shown. Figure 1 In addition to the devices or nodes shown, other devices or nodes may also be included, which is not limited.

[0052] The embodiments provided by the present disclosure are described in detail below in conjunction with the accompanying drawings.

[0053] Figure 3 The following is a flow chart of a communication method provided by an embodiment of the present disclosure. Figure 3 As shown, the method is applied to a first unit of a wireless access network, comprising:

[0054] S101. Receive perception configuration information from a second unit of a wireless access network.

[0055] The perception configuration information includes information required by the first unit of the wireless access network to perform the perception task.

[0056] The first unit of the radio access network may be an O-RU or a logical unit with similar functions, and the second unit of the radio access network may be an O-DU or a logical unit with similar functions.

[0057] Implementation method 1: Implement the sensing mode (SensingEstimation based on DU) of the sensing function through the second unit of the wireless access network.

[0058] Exemplarily, the physical layer functions of the perception module can be split and deployed on the second unit of the wireless access network and the first unit of the wireless access network. Among them, the low physical layer functions of the perception module are deployed on the first unit of the wireless access network, and the high physical layer functions thereof are deployed on the second unit of the wireless access network. In this implementation, the generation of the perception result is on the second unit of the wireless access network, so this implementation can also be called Sensing Estimation based on DU.

[0059] For example, Figure 4 As shown, the second unit of the wireless access network can perform sensing reference signal generation (Sensing RS Generation), modulation (Modulation), resource element mapping (RE Mapping), in-phase and orthogonal compression (IQ Compression) and other functions in sensing downlink data flow. The second unit of the wireless access network can perform IQ decompression (IQ Decompression), resource element demapping (RE Demapping), channel estimation (Channel Estimation) and detection (Detection) and other functions in sensing uplink data flow.

[0060] like Figure 4 As shown, the first unit of the wireless access network can perform IQ decompression (IQ Decompression), inverse Fourier transform and CP addition (IFFT and CP Addition), digital-analog conversion (Digital-Analog), and selectively perform analog beamforming (Analog Beamforming) and other functions in sensing the downlink data flow. The first unit of the wireless access network can perform IQ compression (IQ Compression), Fourier transform and CP removal (FFT and CP removal), analog-digital conversion (Analog-Digital), and selectively perform analog beamforming (Analog Beamforming) and other functions in sensing the uplink data flow.

[0061] In some embodiments, the second unit of the wireless access network may send the awareness configuration information to the first unit of the wireless access network. That is, the first unit of the wireless access network may receive the awareness configuration information from the second unit of the wireless access network.

[0062] In one example, during the downlink process of the sensing task, the sensing configuration information includes at least one of the following:

[0063] Fast Fourier transform parameters of the perception reference signal;

[0064] subcarrier spacing of the perception reference signal;

[0065] Resource information of sensing reference signals;

[0066] A symbol indication information of a sensing reference signal;

[0067] Resource set information of sensing reference signals;

[0068] sensing sequence information of a reference signal;

[0069] Compression parameters of the perceptual reference signal;

[0070] the type of cyclic prefix of the perceptual reference signal;

[0071] A transmit power range of a sensing reference signal;

[0072] A sending period of a sensing reference signal;

[0073] Indication information on whether to adopt multi-station collaborative sensing method.

[0074] Among them, the fast Fourier transform parameter is a commonly used technique for processing digital signals, which is used to convert signals from the time domain to the frequency domain. The fast Fourier transform parameter of the perceptual reference signal can define the number of points or size used when performing the fast Fourier transform operation, which can further affect the resolution of the signal in the frequency domain.

[0075] The subcarrier spacing of the perceptual reference signal is used to determine the granularity of the signal in the frequency domain. A smaller subcarrier spacing corresponds to lower bandwidth efficiency and higher spectrum efficiency, that is, a larger subcarrier spacing can be suitable for application scenarios that require fast response.

[0076] The resource information of the perception reference signal is used to indicate the specific position of the perception reference signal in the time-frequency resources, such as the symbol position in time and the subcarrier position in frequency, and may also be an identifier (ID) and the like.

[0077] The symbol indication information of the perception reference signal is used to identify the specific symbol position of the perception reference signal in a radio frame or subframe, thereby helping a receiving end to correctly identify and receive the perception reference signal.

[0078] The resource set information of the perception reference signal may include possible information related to the resource set, such as resource (Resource), resource set identifier (Resourceset ID), resource set periodicity (Resource Set Periodicity) and resource set offset (Resource Setoffset).

[0079] The sequence information of the perception reference signal is used to indicate the specific sequence used by the perception reference signal, and may also be an identifier (ID). These sequences usually have good autocorrelation and cross-correlation characteristics, so as to perform accurate channel estimation and interference measurement at the receiving end.

[0080] The compression parameters of the perceptual reference signal may include the selection of a compression algorithm, a compression ratio, etc. The perceptual reference signal may be compressed before transmission to reduce bandwidth occupancy and transmission delay.

[0081] The types of CP of the perceptual reference signal may include normal CP (NCP) and extended CP (ECP). Different types of CP of perceptual reference signals have different CP lengths. The selection of CP type may affect system performance, such as signal coverage and transmission efficiency.

[0082] The transmit power range of the perception reference signal is used to indicate the upper limit and lower limit of the transmit power of the perception reference signal.

[0083] The sending period of the sensing reference signal is also the sending frequency of the sensing reference signal, that is, how often the sensing reference signal is sent. The sending period of the sensing reference signal can be determined according to the requirements of the sensing task, such as the speed of channel change and the measurement accuracy requirements.

[0084] The indication information of whether to adopt the multi-station coordinated sensing mode is used to indicate whether to adopt multiple base stations or access points to coordinately send or receive sensing reference signals. It should be understood that the multi-station coordinated sensing mode can overcome the blind spot problem and interference problem of single-station sensing, thereby improving the accuracy and reliability of sensing.

[0085] In one example, the second unit of the wireless access network can indicate the start of the perception task to the first unit of the wireless access network through a control plane message (C-plane Message), and send perception configuration information to the first unit of the wireless access network through a C-plane Message / management plane message (M-Plane Message).

[0086] For example, a possible C / M-Plane Message may include the following content:

[0087]

[0088] That is, the C / M-Plane Message includes a field for identifying or carrying information related to the compression of the perceptual reference signal, a fast Fourier transform parameter, an identifier of a resource of the perceptual reference signal, an identifier of a resource set of the perceptual reference signal, a sequence identifier of the perceptual reference signal, a compression parameter of the perceptual reference signal, a type of CP of the perceptual reference signal, a minimum transmit power of the perceptual reference signal, a maximum transmit power of the perceptual reference signal, and a transmission period of the perceptual reference signal.

[0089] In some embodiments, the first unit of the wireless access network may also receive IQ sample data (IQ sample) from the second unit of the wireless access network, and decompress the IQ sample data to obtain a perception reference signal.

[0090] Furthermore, the first unit of the radio access network may also send a sensing reference signal to the second node according to the sensing configuration information. It should be understood that the first unit of the radio access network is on the first node.

[0091] Exemplarily, in this embodiment, the second unit of the wireless access network may also send a compressed IQ sample containing a sensing reference signal (Sensing RS) to the first unit of the wireless access network through a user plane message (U-plane Message). Then, the first unit of the wireless access network may receive the IQ sample from the second unit of the wireless access network, decompress the IQ sample through an IQ decompression function, and then transmit the sensing reference signal to the radio frequency link and send it to the air interface through an inverse Fourier transform, a CP addition function, and a digital-to-analog conversion function.

[0092] In another example, in the uplink process of the sensing task and in the sensing mode of realizing the sensing function by the second unit of the radio access network, the sensing configuration information includes at least one of the following:

[0093] Indicative information of whether the current symbol is a perceptual symbol;

[0094] The number of antennas used to perform the sensing task;

[0095] Reference antenna or port identification information;

[0096] Compression parameters and compression methods of in-phase and quadrature IQ sampling data corresponding to the reference antenna or port;

[0097] Compression parameters and compression methods of IQ sampling data corresponding to non-reference antennas or ports.

[0098] For example, a possible C / M-plane message may include the following content:

[0099] Common Header Fields ......

[0101] referenceantennaCompHdr(Compression header of IQ samples forreference antenna)

[0102] nonreferenceantennaCompHdr(Compression header of IQ samples for non-reference antenna) ......

[0104] Section Header Fields ......

[0106] SensingSymbolidentifier:(the identifier of sensing symbol)

[0107] numofantenna:(the number of antennas for sensing)

[0108] referenceantennaID:(the ID of reference antenna)

[0109] numofbitsforreferenceantennaComp:(the number of bits for referenceantenna compression)

[0110] numofbitsfornonreferenceantenna:(the number of bits for non-referenceantenna compression)

[0111] referenceantennaCompParam:(the compression method)

[0112] nonreferenceantennaCompParam:(the compression method)

[0113] Among them, SensingSymbolidentifier is a 1-bit message used to indicate whether the current symbol is a sensing symbol, that is, the indication information of whether the current symbol is a sensing symbol.

[0114] Numofantenna is used to indicate the number of antennas used for perception, that is, the number of antennas used to perform the above-mentioned perception task.

[0115] referenceantennaID is used to indicate the ID corresponding to the reference antenna, that is, the identification information of the reference antenna or port.

[0116] numofbitsforreferenceantenna is used to indicate the number of bits after the IQ sample corresponding to the reference antenna is compressed. For example, the number of bits of the IQ sample after the reference antenna is compressed is 8 bits, and the number of bits of the IQ sample after the non-reference antenna is compressed is 4 bits; referenceantennaCompHdr and

[0117] nonreferenceantennaCompHdr indicates that the compression method can be, for example, amplitude difference, phase difference, or both amplitude and phase difference. referenceantennaCompParam and

[0118] nonreferenceantennaCompParam represents the parameters used for compression, that is, the compression parameters and compression method of the in-phase orthogonal IQ sampling data corresponding to the above-mentioned reference antenna or port, and the compression parameters and compression method of the IQ sampling data corresponding to the non-reference antenna or port.

[0119] Exemplarily, the resource element (RE) corresponding to the reference antenna and the RE corresponding to the non-reference antenna are as follows: Figure 5 As shown, its antenna dimension compression can be shown in Table 1. Among them, iSample(1stRE in the PRB1Antenna 1) can indicate the first resource element (1stRE in the first physical resource block (PRB 1) and the first antenna (Antenna 1). st RE) is sampled.

[0120] Table 1

[0121]

[0122]

[0123] In some embodiments, the first wireless access network unit may also send identification information related to the airspace corresponding to the sensing data to the second wireless access network unit.

[0124] Exemplarily, after receiving the above C / M-plane message, the first unit of the wireless access network can report a U-plane message to the second unit of the wireless access network, and the reported U-plane message needs to include the Antenna ID corresponding to the IQ sample (identification information related to the airspace corresponding to the perception data). That is, the antenna ID information needs to be added to the header field (header) of the U-plane. For example, the U-plane message may include:

[0125] Common header fields ......

[0127] Section Fields ......

[0129] AntennaID: (the antenna ID of each IQ sample)

[0130] Implementation method 2: realizing the perception mode of the perception function through the first unit of the wireless access network.

[0131] Exemplarily, the physical layer functions of the perception module may all be deployed on the first unit of the wireless access network.

[0132] It should be noted that there is a delay error between the first unit of the wireless access network and the second unit of the wireless access network, which may affect the accuracy of the final perception result. Therefore, all physical layer functions of the perception module can be deployed in the first unit of the wireless access network to reduce this impact.

[0133] For example, Figure 6 As shown, the second unit of the wireless access network can perform functions such as sensing reference signal generation, modulation, resource element mapping, in-phase and orthogonal compression in sensing downlink data flow. The first unit of the wireless access network can perform functions such as IQ decompression, inverse Fourier transform and CP addition, digital-to-analog conversion, and selectively perform analog beamforming in sensing downlink data flow.

[0134] In the perception uplink data flow, the perception-related physical layer functions such as resource element demapping, channel estimation and detection are all located in the first unit of the wireless access network. In addition, the original IQ compression and IQ decompression are retained between the first unit of the wireless access network and the second unit of the wireless access network, that is, the FH-U interface is retained.

[0135] In some embodiments, the second unit of the wireless access network may send the awareness configuration information to the first unit of the wireless access network. That is, the first unit of the wireless access network may receive the awareness configuration information from the second unit of the wireless access network.

[0136] In one example, during the downlink process of the sensing task, the sensing configuration information includes at least one of the following:

[0137] Fast Fourier transform parameters of the perception reference signal;

[0138] subcarrier spacing of the perception reference signal;

[0139] Resource information of sensing reference signals;

[0140] A symbol indication information of a sensing reference signal;

[0141] Resource set information of sensing reference signals;

[0142] sensing sequence information of a reference signal;

[0143] Compression parameters of the perceptual reference signal;

[0144] the type of cyclic prefix of the perceptual reference signal;

[0145] A transmit power range of a sensing reference signal;

[0146] A sending period of a sensing reference signal;

[0147] Indication information on whether to adopt multi-station collaborative sensing method.

[0148] In one example, the second unit of the wireless access network can indicate the start of the perception task to the first unit of the wireless access network through a control plane message (C-plane Message), and send perception configuration information to the first unit of the wireless access network through a C-plane Message / management plane message (M-plane Message).

[0149] In another example, in the uplink process of the sensing task, and in the sensing mode in which the sensing function is realized by the first unit of the radio access network, the sensing configuration information further includes at least one of the following:

[0150] a transmission direction of the sensing data generated by the first unit of the wireless access network;

[0151] The number of symbols that the first unit of the wireless access network needs to cache to perform a sensing task;

[0152] Perceive the position information of symbols in the time domain;

[0153] The fast Fourier transform parameters used when estimating Doppler shift;

[0154] Perceive the comb information of the reference signal in the time-frequency domain;

[0155] Resource set information of the perception reference signal.

[0156] Exemplarily, the transmission direction of the perception data generated by the first unit of the radio access network is ORUdatadirection (the data direction for O-RU to transmit U-plane message).

[0157] In this implementation, an NG-U interface is added to the O-RU. At this time, the O-RU can directly exchange information with the U-plane of the core network through the NG-U interface. Among them, the second unit of the wireless access network can send a 1-bit C / M-plane message to the first unit of the wireless access network. The C / M-plane message instructs the first unit of the wireless access network to send the perception estimation results such as time of arrival (TOA), angle of arrival (AOA) and Doppler shift parameters to the second unit of the wireless access network through the interface FH-U. Then, the second unit of the wireless access network sends it to the core network through the third unit of the wireless access network, such as the wireless access network central unit (O-CU), or the second unit of the wireless access network directly sends it to the core network through the interface NG-U.

[0158] Afterwards, the second unit of the wireless access network can send the start of the sensing service and the position of the sensing symbol in each time slot, the number of symbols that the first unit of the wireless access network needs to cache, the fast Fourier transform parameters used for Doppler frequency shift estimation, for example, a 128-point FFT may be required for receiving 100 sensing symbols, the comb information of the sensing reference signal in the time and frequency domain, such as CombSize, and the resource set information of the sensing reference signal, such as resources (Resource), resource set identifier (Resource set ID), resource set periodicity (Resource Set Periodicity) and resource set offset (Resource Set offset) and other possible information related to the resource set to the resource set.

[0159] For example, a possible C-Plane Message may include the following content:

[0160]

[0161] resource set ID(the ID of sensing RS resource set)

[0162] resource set periodicity (the periodicity of sensing RS resource set)

[0163] resource slot offset (the slot offset of sensing RS resource)

[0164] resource symbol offset(the symbol offset of sensing RS resource)

[0165] Wherein, symbolIdforsensing is used to indicate the position of the sensing symbol in each time slot.

[0166] numofSymbolstoBuffer is used to indicate the number of symbols that need to be cached for perception.

[0167] Combsize is used to indicate the perceived Combsize, for example, 000 corresponds to Comb1, 001 corresponds to Comb2, 010 corresponds to Comb4, 011 corresponds to Comb6 (for example, when the terminal side sends and the network device side receives, the terminal side sends UL-SRS as Sensing RS), 100 corresponds to Comb8, and 101 corresponds to Comb12.

[0168] FFTsizeforDoppler is used to indicate the size of the fast Fourier transform parameters of the cached perception symbols in the Doppler dimension.

[0169] resource ID indicates the sensing RS resource ID.

[0170] resource set ID indicates the sensing RS resource set ID.

[0171] Resource set periodicity indicates the sensing RS resource set periodicity.

[0172] Resource slot offset indicates the offset of sensing RS resources in the time slot.

[0173] Resource symbol offset indicates the symbol offset of the sensing RS resource.

[0174] Exemplarily, after receiving the C / M-plane message sent by the second unit of the wireless access network, the first unit of the wireless access network can also obtain the estimation results of the target distance (TOA), angle (AOA) and speed (Doppler shift) by sequentially using the "Analog-Digital", "FFT and CP removal", "RE mapping", "Channel Estimation" and "Detection" functions of the received echo.

[0175] Furthermore, the first unit of the wireless access network can send the estimation result to the second unit of the wireless access network or directly to the core network through the FH-U interface or the NG-U interface according to the C / M-plane message sent by the second unit of the wireless access network.

[0176] When the first unit of the wireless access network sends the data to the second unit of the wireless access network through FH-U, that is, the perception result is reported from the physical layer IQ sample to the second unit of the wireless access network, the second unit of the wireless access network first needs to indicate the compression method and the number of compressed bits of the perception result through the C / M-plane message. For example, the perception result can be compressed into 12 bits, where 0-3 bits represent AOA, 4-7 bits represent TOA, and 8-11 bits represent Doppler shift. Exemplarily, the C / M-plane message may include the following content:

[0177] Common Header Fields

[0178]

[0179] Implementation method 3: multi-station collaborative perception method.

[0180] Exemplarily, the sensing function may be located in the first unit of the radio access network, the second unit of the radio access network, and the third unit of the radio access network.

[0181] like Fig. 7AAs shown, network devices BS B, BS C and BS A can exchange information through a wired Xn interface to complete the task of perceiving the target. Since each BS can obtain the perceived measurement and estimation results (such as TOA / AOA / Doppler shift) about the target, it is necessary to merge and deduplicate the perceived measurement and estimation results of multiple base stations. Exemplarily, a multi-station perception result processing function such as a perception result deduplication function can be added to the perception module at will, and the multi-station perception result processing function can be deployed on the third unit of the wireless access network.

[0182] like Figure 7B As shown, in the perception process, network devices BS B and BS C can transmit perception results (such as TOA / AOA / Doppler shift) to BS B through the Xn interface. Among them, network device BS A serves as a serving BS, and the third unit of the wireless access network of the network device BS A is deployed with a "Combine and Filtering" function for processing the merging and deduplication of perception results between multiple stations, which can be responsible for filtering and deduplication of perception results between multiple stations.

[0183] Exemplarily, similar to the above-mentioned implementation method 1, the second unit of the wireless access network sequentially sends the C / M-plane message and the perception reference signal to the first unit of the wireless access network in the perception downlink data stream. The first unit of the wireless access network can process the IQ sample compressed by the received perception reference signal through the "IQ Decompression", "IFFTand CP Addition", and "Digital-Analog" functions and send it to the air interface through the RF link.

[0184] During the perception uplink process, since the perception module functions may be located on the first unit of the wireless access network and the second unit of the wireless access network respectively (as shown in implementation method 1) or may be all located on the O-RU (as shown in implementation method 2), the second unit of the wireless access network may first send 1 bit of perception function logical unit selection information (SensingEstimationmode(sensing mode)) to all first units of the wireless access network participating in the perception through the C / M-plane message, for example, it may be a perception mode "Sensing Estimation based on O-DU" for implementing the perception function through the second unit of the wireless access network, or a perception mode "Sensing Estimationbased on O-RU" for implementing the perception function through the first unit of the wireless access network.

[0185] Furthermore, the second unit of the wireless access network may send a corresponding C / M-plane message to the first unit of the wireless access network according to different functional configurations of the perception module of the first unit of the wireless access network.

[0186] For example, the first unit of the wireless access network is configured as "Sensing Estimation based on DU", which corresponds to the above implementation 1. At this time, the first unit of the wireless access network can refer to the above implementation 1 to send the received echo signal to the second unit of the wireless access network through the FH-U interface.

[0187] It should be understood that the perception configuration information received by the first unit of the wireless access network at this time can also refer to the above-mentioned implementation method 1, which will not be repeated here.

[0188] For another example, the first unit of the wireless access network is configured as "Sensing Estimation based on RU", which corresponds to the above implementation method 2. At this time, the first unit of the wireless access network can refer to the above implementation method 2 to obtain the perception target estimation result of the received echo signal through the "Analog-Digital", "FFT and CP removal", "RE DeMapping", "ChannelEstimation" and "Detection" functions, and compress the perception estimation result through "IQCompression" and send it to the second unit of the wireless access network. Among them, the "ORUdatadirection" sent by the second unit of the wireless access network points to the FH-U interface.

[0189] It should be understood that the perception configuration information received by the first unit of the wireless access network at this time can also refer to the above-mentioned implementation method 2, which will not be repeated here.

[0190] In some embodiments, the first unit of the wireless access network may also send indication information for indicating the information type of the sensing data to the second unit of the wireless access network. The type of the sensing data may include sensing results or target reflection echo frequency domain data.

[0191] Exemplarily, since the U-plane message may contain a perceived target echo or a perceived target estimation result, the first unit of the wireless access network may add 1 bit of indication information to the header of the U-plane message, and the indication information is used to indicate the content type contained in the U-plane message. For example, "0" represents a target reflection echo or a channel information frequency domain data IQ sample, and "1" represents a perceived estimation result IQ sample.

[0192] Common header fields ......

[0194] typeofsensingUplanemessage:(the type of U-plane message)field 1Bit ......

[0196] In some embodiments, the first wireless access network unit is on the first node, and the first wireless access network unit may send the sensing result information to the third wireless access network unit through the second wireless access network unit.

[0197] Exemplarily, the first unit of the wireless access network receives a U-plane message, and can generate perception result information for the IQ sample of the target reflection echo or the frequency domain data of the channel information through the "IQDecompression", "RE Demapping", "Channel Estimation" and "Detection" functions in sequence based on the instruction of the second unit of the wireless access network. Then, the first unit of the wireless access network can send the perception result information to the third unit of the wireless access network through the F1-U interface. For the IQ sample of the perception result, it can be sent directly to the third unit of the wireless access network through the F1-U interface after "IQDecompression" based on the instruction of the second unit of the wireless access network.

[0198] Furthermore, the third unit of the wireless access network corresponding to the network devices BS B and BS C can obtain the perception estimation result information (such as TOA / AOA / Doppler shift) and send it to the third unit of the wireless access network corresponding to BS A through the Xn interface. The third unit of the wireless access network corresponding to BS-A can use the "Combine and Filtering" function to deduplicate and filter all perception results and then report them to the core network (third node).

[0199] Implementation method 4: a multi-station collaborative perception method, in which the second unit of the wireless access network collaborates with multiple first units of the wireless access network to perform multi-station perception.

[0200] The multi-station sensing performed by the second unit of the wireless access network in collaboration with a plurality of first units of the wireless access network may include at least two possible modes: fronthaul multiplexer (FHM mode) and cascade mode.

[0201] Mode 1, FHM mode.

[0202] FHM can be called the fourth unit of the radio access network. FHM is equivalent to a RU without radio capability, but has the capability of downlink message copy and uplink message combine.

[0203] like Figure 8 As shown, the second radio access network unit can interact with multiple first radio access network units respectively through the fourth radio access network unit FHM.

[0204] In the downlink process of the sensing task, the second unit of the wireless access network may first send messages to N first units of the wireless access network respectively through FHM, where N is a positive integer. Exemplarily, the message may be a plane message, and the message may include sensing configuration information, which may include any of the following:

[0205] Identification information of a first unit of a wireless access network participating in multi-station collaborative sensing, such as an identification list;

[0206] Beam identification information corresponding to each first unit of the radio access network, such as an identifier, and the beam directions of the first units of different radio access networks may be different;

[0207] The effective sensing area information of each first unit of the wireless access network may be, for example, the radius and angle of the sensing sector of each first unit of the wireless access network, the cell ID or sector ID, the longitude and latitude coordinates of the sensing area, etc.;

[0208] a transmission power range of the first unit of each radio access network;

[0209] Resource set information corresponding to each first unit of the radio access network, such as Resource set ID and Resource ID corresponding to each first unit of the radio access network;

[0210] Sequence information of the perception reference signal corresponding to each first unit of the radio access network, such as a Sequence ID list.

[0211] Exemplarily, the plane message may include the following content:

[0212]

[0213] Thus, for any first unit of the wireless access network, during the downlink process of the perception task, the perception configuration information received from the second unit of the wireless access network may include the identification information of the first unit of the wireless access network participating in multi-station collaborative perception, the identification information of the beam corresponding to the first unit of the wireless access network, the effective perception area information of the first unit of the wireless access network, the transmission power range of the first unit of the wireless access network, the resource set information corresponding to the first unit of the wireless access network, and the sequence information of the perception reference signal corresponding to the first unit of the wireless access network.

[0214] Furthermore, the second radio access network unit can also send a U-plane message containing Sensing RS to each first radio access network unit (through the fourth radio access network unit). The IQ sample containing Sensing RS that can be received by each O-RU is decompressed through "IQ Decompression" and sent to the air interface by the RF link and receives the target echo.

[0215] Exemplarily, the first unit of the wireless access network is on the first node and can also send a perception reference signal to the second node according to the perception configuration information.

[0216] During the uplink process of the sensing task, the second unit of the wireless access network may first send the sensing function logic unit list information (SensingEstimationmodeList(sensing modes of all O-RUs)) to each first unit of the wireless access network through the M-plane message. For example, O-RU#1 may be a sensing mode for implementing the sensing function through the second unit of the wireless access network, Sensing Estimation based on O-DU, or may be O-RU#N, a sensing mode for implementing the sensing function through the Nth first unit of the wireless access network, SensingEstimation based on O-RU. In some embodiments, the M-plane message may be sent through the FHM, or the M-plane message may be sent directly without going through the FHM.

[0217] In some embodiments, the second unit of the wireless access network may also send a C-plane message to each first unit of the wireless access network (through FHM), where the C-plane message may include sensing configuration information or other possible information. The specific description of the C-plane message may refer to the above-mentioned implementation method 1 (corresponding to Sensing Estimation based on O-DU) or implementation method 2 (corresponding to Sensing Estimation based on O-RU), which will not be repeated here.

[0218] Furthermore, each first unit of the radio access network may process the received echo according to the M-plane message and the C-plane message sent by the second unit of the radio access network.

[0219] Exemplarily, in the case of configuration as “Sensing Estimation based on O-RU”, the first unit of the radio access network may generate sensing result information of the sensing target, for example

[0220] Estimation results of TOA / AOA / Doppler shift. Alternatively, when configured as "Sensing Estimationbased on O-DU", the first unit of the wireless access network can generate target echo or channel information frequency domain data. The first unit of the wireless access network can compress the generated data (such as perception results or target echo frequency domain data) through the "IQCompression" function and report it to the FHM. In some embodiments, the first unit of the wireless access network can also add the ID information of the first unit of the wireless access network to the U-plane message header. In some examples, a perception mode identifier can also be included. For example:

[0221] Common header fields ......

[0223] IDofORU:(the ID of O-RU)field 8Bit ......

[0225] That is, the first unit of the wireless access network can also send the identity (ID information) and the sensing mode identifier of the first unit of the wireless access network to the second unit of the wireless network through the FHM, such as the identification information of "Sensing Estimation based on O-DU". The first unit of the wireless access network sends the identity and the sensing mode identifier to the FHM, and then the FHM sends the identity and the sensing mode identifier of the first unit of the wireless access network to the second unit of the wireless network.

[0226] In some embodiments, the FHM may merge U-plane messages of different radio access network first units and generate a new U-plane message header. The generated header may include a list of radio access network first units corresponding to different types of U-plane messages. For example:

[0227]

[0228] Among them, ORUIDlistforsensingtype0 corresponds to the first unit of the wireless access network that only performs sensing-related low physical layer processing, such as Figure 8 In the radio access network first unit #1 and the radio access network first unit #2, ORUIDlistforsensingtype1 corresponds to the radio access network first unit that performs sensing-related high physical layer processing, such as O-RU#N.

[0229] In some embodiments, after receiving the IQ samples of different O-RUs reported by the FHM, the second unit of the wireless access network can first decompress them through "IQ Decompression", and then the IQ samples corresponding to ORUIDlistforsensingtype0 can be processed through "RE Demapping", "ChannelEstimation", and "Detection" functions to obtain the perception estimation results, such as TOA / AOA / ZOA / Doppler shift. Furthermore, it can also be processed with the perception estimation results of the remaining first units of the wireless access network (such as O-RU#N) through the "Combine and Filtering" function to obtain the multi-station collaborative perception estimation results.

[0230] Mode 2: Cascade mode.

[0231] like Fig. 9As shown, the cascade mode can utilize the cascade between multiple wireless access network first units to realize the signaling interaction between the wireless access network second unit and multiple wireless access network first units. Among them, the wireless access network first unit can receive downlink information from the wireless access network first unit of the upper level (north node) and forward it to the wireless access network first unit of the lower level (south node).

[0232] During the downlink process of the perception task, the first unit of the wireless access network at each level can directly send the information from the previous level to the wireless access network unit at the next level without any modification. In this way, its downlink process is similar to the above-mentioned FHM mode. Please refer to the relevant description of the downlink process of the perception task of the above-mentioned FHM mode, which will not be repeated here.

[0233] During the uplink process of the perception task, each first unit of the wireless access network can also receive the perception target echo from the air interface and generate a corresponding IQ sample when receiving the uplink data of the next level. In this way, the amount of data transmitted between the cascade links will increase rapidly during the uplink process. Therefore, based on the cascade link formed by the first unit of the wireless access network and at least one other first unit of the wireless access network, the first unit of the wireless access network can send at least one of the position information of the first unit of the wireless access network on the cascade link, the remaining space information in the stack, and the indication information of the adjusted perception mode to the first unit of the wireless access network at the upper level on the cascade link.

[0234] Exemplarily, the amount of data in the sensing mode "Sensing Estimation based on DU" is much larger than the amount of data in the sensing mode "Sensing Estimation based on RU". The first unit of the wireless access network may send the position information of the first unit of the wireless access network on the cascade link and / or the remaining space information in the stack to the first unit of the wireless access network at the upper level on the cascade link, so that the first unit of the wireless access network may determine whether it is necessary to adjust the sensing mode or the sensing estimation mode configured for the second unit of the wireless access network based on the position information and / or the remaining space information in the stack.

[0235] In the uplink process of the perception task, the second unit of the wireless access network can first send a C-plane message to all the first units of the wireless access network in the link. The C-plane message may include perception configuration information or other possible information. The specific description of the C-plane message can refer to the description of the C-plane message of the uplink process in the above FHM mode, which will not be repeated here. Thus, each first unit of the wireless access network receives the C-plane message sent by the first unit of the upper-level wireless access network in turn.

[0236] Furthermore, the second unit of the wireless access network may sequentially send a U-plane message containing a perception reference signal to the first unit of the wireless access network, and then each first unit of the wireless access network may send the perception reference signal to the air interface through its own radio frequency link.

[0237] In some embodiments, during the uplink process of the sensing task, the second unit of the wireless access network may first send an M-plane message to all the first units of the wireless access network in the link, and the M-plane message is used to configure the sensing estimation mode "Sensing Estimation mode" of each first unit of the wireless access network. Then, the first unit of the wireless access network at the lowest level of the link may start to receive the echo signal of the sensing target, and generate corresponding M-plane messages and U-plane messages according to the configured sensing estimation mode. Among them, the M-plane message may include the location information and / or the remaining space information in the stack that the first unit of the wireless access network can use. For example, the M-plane message may include the following content:

[0238] ExistingIDinsharedchain: (the existing ID of O-RUs in the sharedchain)field:8bits

[0239] Remainingspaceinstack:(the remaining space in the stack)field:16bits

[0240] Among them, ExistingIDinsharedchain is used to indicate the position of the first unit of the current radio access network in the entire cascade link (for example, the ID corresponding to the O-RU at the bottom layer is 0, and so on).

[0241] Remainingspaceinstack is used to indicate the remaining space size in the protocol stack.

[0242] For the first unit of the wireless access network on the link, after receiving the M-plane message of the first unit of the wireless access network at the next level, it can adjust its own "Sensing Estimation mode" according to the first unit identifier of the wireless access network that has appeared and the remaining space in the stack. Exemplarily, when the space in the stack is insufficient, the first unit of the wireless access network can adjust its own "Sensing Estimation mode" from "Estimation on DU" to "Estimation on RU", and update the type0 identifier list "IDlistfortype0" and the type1 identifier list "IDlistfortype1" in the M-plane message after the adjustment.

[0243] In some embodiments, the first unit of the wireless access network may also merge the U-plane messages, and specific reference may be made to the merging method in the above FHM mode, for example, all IQ samples of "ORUIDlistforsensingtype0" may be merged, and all IQ samples of "ORUIDlistforsensingtype1" may be merged.

[0244] Furthermore, the first unit of the wireless access network can send the updated C-plane message and the merged U-plane message to the first unit of the wireless access network at the next level on the link, and so on, until it is transmitted to the first unit of the wireless access network at the top level.

[0245] Based on the technical solution provided by the present disclosure, when the corresponding perception function is deployed inside the network device, the signaling interaction between various wireless access network units during the perception process, that is, various signaling interactions inside the network device, can be realized. In this way, the application and development of the synaesthesia integration technology in network devices can be facilitated.

[0246] In some embodiments, based on the above implementations, the first wireless access network unit may also send its own sensing capability information to the second wireless access network unit.

[0247] In one example, Fig. 10A As shown, the first unit of the wireless access network can directly send its own perception capability information to the second unit of the wireless access network. The first unit of the wireless access network can send its own perception capability information to the second unit of the wireless access network via an M-plane message.

[0248] In another example, Fig. 10BAs shown, the first unit of the wireless access network receives the sensing capability reporting request information from the second unit of the wireless access network. In response to the sensing capability reporting request information, the first unit of the wireless access network sends its own sensing capability information to the second unit of the wireless access network.

[0249] The sensing capability reporting request information may be carried in a C-plane message or an M-plane message. Furthermore, the first wireless access network unit may also send its own sensing capability information to the second wireless access network unit via an M-plane message.

[0258] Indication information of whether the first radio access network unit supports the cooperative sensing controlled by the second radio access network unit.

[0267] The maximum transmission bandwidth supported by the first unit of the wireless access network;

[0268] A receiving power range supported by the first unit of the radio access network.

[0269] In some embodiments, during the uplink process of the perception task, when the first wireless access network unit supports the indication information of the shared wireless access network second unit, it may also include a mode of the shared wireless access network second unit (Shared Cell) supported by the first wireless access network unit.

[0270] In one possible example, Fig.11 As shown, the sensing process may include steps S1-S10.

[0271] S1. The second unit of the wireless access network sends a downlink perception capability reporting request message to the first unit of the wireless access network.

[0272] Among them, step S1 is optional.
