The wireless communication system includes a first device, a second device, a core network, and an application server; wherein the first device may be a terminal, and the second device may be a terminal or a network-side device. Figure 1 The second device is used as an example to illustrate the network side device.
[0046] In this application embodiment, the terminal can be a mobile phone, tablet computer, laptop computer (also known as a notebook computer), personal digital assistant (PDA), handheld computer, netbook, ultra-mobile personal computer (UMPC), mobile internet device (MID), augmented reality (AR) / virtual reality (VR) device, robot, wearable device, vehicle-mounted device (VUE), pedestrian terminal (PUE), smart home (home devices with wireless communication functions, such as refrigerators, televisions, washing machines, or furniture), game console, personal computer (PC), ATM or self-service machine, etc. Wearable devices include: smartwatches, smart bracelets, smart headphones, smart glasses, smart jewelry (smart bracelets, smart chains, smart rings, smart necklaces, smart anklets, smart anklets, etc.), smart wristbands, smart clothing, etc. It should be noted that this application embodiment does not limit the specific type of terminal.
[0047] Network-side equipment may include access network equipment or core network equipment. Access network equipment may also be referred to as radio access network equipment, radio access network (RAN), radio access network function, or radio access network unit. Access network equipment 12 may include base stations, WLAN access points, or WiFi nodes, etc. Base stations may be referred to as Node B, evolved Node B (eNB), access point, base transceiver station (BTS), radio base station, radio transceiver, Basic Service Set (BSS), Extended Service Set (ESS), home B node, home evolved B node, Transmitting Receiving Point (TRP), or any other suitable term in the field, as long as the same technical effect is achieved.

[0048] In this embodiment, both the first and second devices possess sensing capabilities. These sensing devices can perceive information such as the location, distance, and speed of a target object through the transmission and reception of wireless signals, or perform sensing operations such as detection, tracking, identification, and imaging of the target object, event, or environment. For example, in some scenarios or implementations, the sensing categories may be as shown in Table 1 below:
[0049] Table 1
[0050]
[0051] It should be noted that the perception categories shown in Table 1 above are merely illustrative examples, and the categories of perception measurements are not limited in this application embodiment.
[0052] In addition, the purposes of sensing in this application embodiment can be divided into two main categories. The first category is sensing for the purpose of assisting communication or enhancing communication performance, such as: the first device provides more accurate beamforming alignment of the device by tracking the movement trajectory of the device; the other category is sensing that is not directly related to communication, such as: the first device monitors weather conditions through wireless signals, such as a mobile phone recognizing the user's gestures through millimeter wave wireless sensing, etc.
[0053] In this application embodiment, the sensing method may include active sensing, passive sensing, and interactive sensing;
[0054] Active sensing can refer to a device using the reflected signal (e.g., echo) of its own transmitted signal for sensing. Transceivers located in the same area can use different antennas to sense information about their surrounding environment. For example: Figure 2 As shown, the base station uses the reflected signal of its own transmitted signal for sensing.
[0055] Passive sensing can refer to a situation where transceivers are located in different positions, and the receiver uses wireless signals emitted by the transmitter to sense the environment. For example, a first device senses environmental information between itself and another device by receiving wireless signals from that device. Figure 3 As shown, base station 1 transmits a signal, and base station 2 and the terminal sense the signal reflected from the target.
[0056] Interactive perception can be a process in which the perceiver and the target object agree on the subject, time, frequency, format, etc. of electromagnetic wave transmission through information exchange, thereby completing the perception process.
[0057] In some scenarios or implementations of this application, both wireless communication signals and wireless sensing signals will be supported simultaneously. Through signal joint design and / or hardware sharing, and other integrated communication and sensing methods, the integrated design of communication and sensing functions can be achieved. This allows for sensing capabilities or the provision of sensing services while transmitting information. Such integration of communication and sensing can achieve effects such as cost savings, reduced device size, lower device power consumption, improved spectrum efficiency, reduced mutual interference between sensing signals, and enhanced system performance.
[0058] In addition, the integration of sensing can include, but is not limited to, at least one of the following:
[0059] The same network provides both communication and sensing services;
[0060] The same terminal provides both communication and sensing services;
[0061] The same spectrum provides both communication and sensing services;
[0062] Integrated sensing and communication services are completed in a single radio transmission, namely the joint design of communication signals and sensing signals.
[0063] Furthermore, in the field of sensory integration technology, waveform integration can be achieved as follows: Figure 4 As shown, waveform multiplexing includes waveform sharing. Waveform multiplexing includes time division multiplexing, frequency division multiplexing, space division multiplexing, and code division multiplexing, while waveform sharing includes communication-based, sensing-based, and communication-sensing joint optimization.
[0064] The following description, in conjunction with the accompanying drawings, details a sensing measurement method, a sensing measurement indication method, a terminal, and a network-side device provided in this application, through some embodiments and application scenarios.
[0065] Please see Figure 5 , Figure 5 This is a flowchart of a sensing measurement method provided in an embodiment of this application, such as... Figure 5 As shown, the steps include:
[0066] Step 501: The terminal receives PEI, which includes perception indication information.
[0067] The aforementioned PEI can be a PEI sent by the network-side device received by the terminal, and the aforementioned steps can be performed by the terminal receiving the PEI in an idle state or an inactive state.
[0068] The aforementioned perception indication information can be used to instruct the terminal on perception-related behaviors, specifically instructing the terminal to perform perception measurements, report perception measurement quantities, or send signals for performing perception measurements. Furthermore, the aforementioned perception indication information can also be used to instruct the terminal on perception-related behaviors in idle and / or inactive states.
[0069] The aforementioned PEI can also be control signaling carried by PDCCH, or sequence-based control signaling.
[0070] Step 502: The terminal performs a target operation based on the sensing indication information, the target operation including at least one of the following:
[0071] The first signal is sensed and measured, and the sensed measurement is reported.
[0072] A second signal is sent to the target device for the target device to perform sensing measurements.
[0073] The aforementioned first signal can be sent to the terminal by network-side equipment, or it can be sent to the aforementioned terminal by other terminals. For example, the aforementioned first signal can be a first signal sent by at least one of the following: base station, TRP, access point (AP), relay or reconfigurable intelligence surface (RIS), terminal, etc.
[0074] The aforementioned reported sensing measurement results can be reported by the terminal to the network-side device, or the terminal can report to other terminals.
[0075] The target device may include at least one of network-side devices, terminals, TRPs, APs, relays, RISs, etc. Wherein, if the target device includes a terminal, the terminal may be a terminal that performs device-to-device (D2D) communication with the aforementioned terminal.
[0076] It should be noted that in the embodiments of this application, the first signal can be a signal sent by one or more devices, and the second signal can be a signal sent to one or more devices.
[0077] In this embodiment of the application, the first signal may include, but is not limited to, at least one of the following:
[0078] Sensing signal, reference signal, synchronization signal.
[0079] The aforementioned sensing signal may be a newly defined sensing signal for performing sensing measurements in this application embodiment, or it may be a sensing signal defined in the protocol.
[0080] The reference signal included in the first signal mentioned above may include, but is not limited to, at least one of the following:
[0081] Channel State Information Reference Signal (CSI-RS), Positioning Reference Signal (PRS), Demodulation Reference Signal (DMRS), Phase Tracking Reference Signal (PTRS), and Tracking Reference Signal (TRS).
[0082] In this embodiment of the application, the second signal may include, but is not limited to, at least one of the following:
[0083] Sensing signal, reference signal, synchronization signal.
[0084] The reference signal included in the second signal may include, but is not limited to, at least one of the following:
[0085] Preamble, Sounding Reference Signal (SRS), DMRS, and PTRS.
[0086] The synchronization signal included in the first signal mentioned above includes, but is not limited to, at least one of the following:
[0087] Primary Synchronization Signal (PSS), Secondary Synchronization Signal (SSS), and Synchronization Signal Block (SSB).
[0088] The first and second signals mentioned above can also be sensing signals, reference signals, and synchronization signals in a sidelink system.
[0089] In this embodiment of the application, the above steps enable the terminal to perform the target operation according to the perception indication information included in the PEI, thereby improving the perception performance of the terminal.
[0090] As an optional implementation, the sensing indication information includes at least one of the following:
[0091] The first signal includes indication information, sensing measurement information, resource information for reporting sensing measurement, terminal grouping information, reporting method of sensing measurement, resource information for sending the second signal, indication information of the second signal, sending method of the second signal, and terminal identification information for sending the second signal.
[0092] The indication information of the aforementioned first signal includes, but is not limited to, at least one of the following:
[0093] The identification information of the first signal, the detection period of the first signal, the detection offset of the first signal, and the terminal identification information corresponding to the first signal.
[0094] The identification information of the first signal can be an index of the first signal, and the identification information can be used to flexibly instruct the terminal to perceive different signals.
[0095] By using at least one of the detection period and detection offset of the first signal mentioned above, the terminal can perform sensing measurements only at the corresponding location, thereby saving the terminal's power consumption.
[0096] The terminal identification information corresponding to the first signal can be a terminal identifier or a terminal group identifier. Through this terminal identification information, it is possible to instruct only the terminal corresponding to the terminal identification information to perform sensing and measurement of the first signal.
[0097] The aforementioned sensing measurement information can indicate to the terminal what needs to be measured for the first signal. For example, the aforementioned sensing measurement information may include at least one of the following:
[0098] Channel matrix, channel state information, reference signal received power, received signal strength indication, channel power delay spectrum, Doppler power spectrum, Doppler spread, coherence bandwidth, coherence time, power of each path in the multipath channel, delay of each path in the multipath channel, angle of each path in the multipath channel, Doppler frequency shift, quotient of the frequency domain channel response of the first antenna and the second antenna, conjugate product of the frequency domain channel response of the first antenna and the second antenna, amplitude ratio of the received signals of the first antenna and the second antenna, amplitude difference of the received signals of the first antenna and the second antenna, phase difference of the first antenna and the second antenna, and angle-related information of the first antenna and the second antenna.
[0099] The first antenna and the second antenna are the receiving antennas of the terminal.
[0100] The aforementioned perceived measurement information can also be a measurement obtained after performing simple operations (including addition, subtraction, multiplication, division, matrix addition, subtraction, multiplication, matrix transpose, trigonometric operations, square root operations, power operations, etc., as well as threshold detection results and maximum / minimum value extraction results of the above operations) on at least one of the above items, or a measurement obtained after performing complex operations (including Fast Fourier Transform (FFT) / Inverse Fast Fourier Transform (IFFT), Discrete Fourier Transform (DFT) / Inverse Discrete Fourier Transform (IDFT), 2D-FFT, 3D-FFT, matched filtering, autocorrelation operations, wavelet transform, digital filtering, etc., as well as threshold detection results and maximum / minimum value extraction results of the above operations).
[0101] The aforementioned channel state information may include, but is not limited to: the amplitude and / or phase of the domain channel response, and the I-channel and Q-channel signal characteristics of the frequency domain channel response. The I-channel and Q-channel signal characteristics may include the amplitudes of the I-channel and Q-channel signals.
[0102] At least one of the above can be indicated according to actual scenario requirements or business requirements, so that the terminal can obtain the corresponding perceived measurement quantity, thereby improving the accuracy of the perceived measurement quantity reported by the terminal.
[0103] Furthermore, the aforementioned sensing measurement information may also include granularity information of the sensing measurement, which can make the sensing measurement reported by the terminal more accurate.
[0104] The resource information for reporting sensing measurements may include at least one of the frequency domain resources and time domain resources for reporting sensing measurements.
[0105] The aforementioned terminal grouping information can indicate the terminal group corresponding to the aforementioned sensing indication information. For example, in PEI, each group corresponds to 2 bits, and the position of these 2 bits represents the group identifier, as shown in Table 2.
[0106] Table 2:
[0107]
[0108] The above-mentioned reporting method for sensed measurements can represent the reporting method of the terminal for sensed measurements. For example, the reporting method for sensed measurements may include the following:
[0109] Initiate a Short Data Transfer (SDT) process to report the sensed measurement;
[0110] Initiate random access to report sensing measurements.
[0111] The aforementioned SDT process can be a configured grant (CG) SDT process, or it can be a non-CG SDT process. Furthermore, the relevant configurations for the aforementioned SDT process can be specified by the network-side device.
[0112] The aforementioned reporting of sensed measurements during random access can be initiated by the terminal, either during the random access process or after entering the connected state.
[0113] In one implementation, the network-side device can determine the reporting method based on the sensing requirements. The terminal does not need to determine the relationship between the data size and the SDT threshold, but can directly report based on the instructions of the network-side device.
[0114] In one implementation, the reporting method is associated with the data size of the measurement result corresponding to the perceived measurement quantity, and is determined by the network-side device or terminal. For example, if the data size of the measurement result is ≤ threshold 1, the SDT process is initiated to report the perceived measurement quantity; if threshold 1 is < data size of the measurement result, random access is initiated to report the perceived measurement quantity.
[0115] The resource information for transmitting the second signal may include at least one of frequency domain resources and time domain resources.
[0116] The indication information of the second signal may include the identification information of the second signal, such as the index of the second signal.
[0117] The aforementioned method of transmitting the second signal can represent the way the terminal transmits the second signal. For example, the aforementioned method of transmitting the second signal may include the following:
[0118] The second signal is sent during the four-step random access process;
[0119] The second signal is sent during the two-step random access process;
[0120] Initiate the SDT procedure by sending the second signal;
[0121] Initiate random access by sending the second signal.
[0122] In the four-step random access process, sending the second signal can be either sending a preamble for sensing or sending DMRS message 3 (MSG3) for sensing.
[0123] The above-mentioned sending of the second signal during the two-step random access process can be done by sending the preamble of message A (MSG A) for sensing, or by sending the DMRS of MSG A for sensing;
[0124] The above-mentioned sending of the second signal to initiate random access may be done during the random access initiation process or after entering the connected state.
[0125] The terminal identification information that sends the second signal may include the terminal identifier or the terminal group identifier that sends the second signal.
[0126] It should be noted that some of the information included in the above-mentioned sensing indication information may be pre-configured or protocol-defined. For example, some information in the following categories may be pre-configured or protocol-defined: the indication information of the first signal, the sensing measurement information, the resource information for reporting the sensing measurement, the terminal grouping information, the reporting method of the sensing measurement, the resource information for sending the second signal, the indication information of the second signal, the sending method of the second signal, and the terminal identification information for sending the second signal.
[0127] As an optional implementation, the sensing indication information is used to indicate one of the following:
[0128] Indicates that paging PDCCH is not detected;
[0129] Indicates detection of PDCCH;
[0130] Indicator detection and sensing dedicated PDCCH;
[0131] Indicates detection of paging PDCCH and sensing-specific PDCCH.
[0132] The aforementioned sensing-dedicated PDCCH refers to a PDCCH specifically used for sensing. Furthermore, the Radio Network Temporary Identifier (RNTI) of the sensing-dedicated PDCCH can be different from or the same as the Paging RNTI (P-RNTI) of the paging PDCCH; this is not limited. Additionally, the control resource set (CORESET) and search space of the sensing-dedicated PDCCH can also be different from or the same as the CORESET and search space of the paging PDCCH; this is not limited.
[0133] In this implementation, the sensing indication information can be used to flexibly instruct the terminal to perform only the corresponding detection, thereby saving the terminal's power consumption.
[0134] Optionally, the terminal performs a target operation based on the perceived indication information, including at least one of the following:
[0135] When the sensing indication information indicates that a paging PDCCH is to be detected, the terminal detects the paging PDCCH and performs the target operation according to the indication content of the detected paging PDCCH;
[0136] When the sensing indication information indicates the detection of a sensing-dedicated PDCCH, the terminal detects the sensing-dedicated PDCCH and performs the target operation according to the indication content of the detected sensing-dedicated PDCCH;
[0137] When the sensing indication information indicates the detection of a sensing dedicated PDCCH, the terminal detects the sensing dedicated PDCCH and demodulates the Physical Downlink Shared Channel (PDSCH) according to the detected sensing dedicated PDCCH. If the terminal identifier in the PDSCH is associated with the terminal, the target operation is performed according to the indication content of the dedicated PDCCH or the PDSCH.
[0138] When the sensing indication information indicates the detection of paging PDCCH and sensing-dedicated PDCCH, the terminal detects the sensing-dedicated PDCCH and paging PDCCH, and performs the target operation according to the indication content of the detected sensing-dedicated PDCCH;
[0139] When the sensing indication information indicates the detection of paging PDCCH and sensing dedicated PDCCH, the terminal detects the sensing dedicated PDCCH and paging PDCCH, and demodulates PDSCH according to the detected sensing dedicated PDCCH. If the terminal identifier in the PDSCH is associated with the terminal, the target operation is performed according to the indication content of the dedicated PDCCH or the PDSCH.
[0140] The terminal identifier in the PDSCH mentioned above may include the terminal identifier or the identifier of the group to which the terminal belongs.
[0141] In this embodiment, the target operation can be performed according to the indication content of the dedicated PDCCH, the indication content of the PDSCH, or the indication content of the paging PDCCH, so as to improve the terminal's perception performance.
[0142] Optionally, the indication content of the dedicated PDCCH, or the indication content of the PDSCH, or the indication content of the paging PDCCH, includes at least one of the following:
[0143] The first signal includes indication information, sensing measurement information, resource information for reporting sensing measurement, terminal grouping information, reporting method of sensing measurement, resource information for sending the second signal, indication information of the second signal, sending method of the second signal, and terminal identification information for sending the second signal.
[0144] The above-mentioned at least one item can be referred to the corresponding description of the at least one item included in the perception indication information in the above embodiments, which will not be repeated here.
[0145] As an optional implementation, the aforementioned sensing indication information is carried by sensing-related bits in the PEI.
[0146] For example, as shown in Table 3, the bits associated with perception mentioned above are 2 bits, which are used to indicate the behavior of the terminal:
[0147] Table 3:
[0148]
[0149]
[0150] As an optional implementation, the aforementioned sensing indication information is carried by the sensing indication bits associated with the terminal group to which the terminal is located, from at least one set of sensing indication bits carried in the PEI.
[0151] In this embodiment, the PEI mentioned above may include at least one set of sensing indicator bits, each set of sensing indicator bits being associated with a terminal packet. Each set of sensing indicator bits may be 2 bits, as shown in Table 3 above.
[0152] Since a PEI can include at least one set of sensing indicator bits, the sensing behavior of multiple terminal groups can be indicated by a single PEI, thus saving transmission overhead.
[0153] As an optional implementation, the method further includes:
[0154] The terminal receives configuration signaling, which is used to indicate sensing configuration information;
[0155] The terminal performs a target operation based on the perceived indication information, including:
[0156] The terminal performs the target operation based on the perception instruction information and the perception configuration information.

[0160] The terminal performs the target operation based on the target information, which includes the information indicated by the perception instruction information in the perception configuration information.
[0161] This allows the sensing indication information to only indicate the information in the sensing configuration information, without carrying specific information. For example, the sensing indication information only needs to carry the index of the signal, the index of the resource, the index of the sensing measurement, etc., to save PEI overhead.
[0162] It should be noted that this embodiment does not limit the terminal to perform the target operation based on the aforementioned target information. For example, in some embodiments, the aforementioned sensing configuration information may include information unrelated to the content indicated by the aforementioned sensing indication information. This allows the terminal to perform the target operation based on the information indicated by the aforementioned sensing indication information and the sensing configuration information including no additional information related to the content indicated by the aforementioned sensing indication information. For instance, in some embodiments, the aforementioned sensing configuration information configures a unique resource for reporting measurements, so the sensing indication information does not need to indicate resource information for reporting measurements; similarly, in some embodiments, the aforementioned sensing configuration information configures a unique first signal, so the sensing indication information does not need to indicate information about the first signal.
[0163] In the above embodiments, since the terminal performs the target operation based on the perception instruction information and the perception configuration information, PEI overhead can be saved because the perception configuration information does not need to be carried in the PEI.

[0169] Among them, the DMRS corresponding to index 1 refers to the DMRS in System Information Block (SIB) 1, the DMRS corresponding to index 5 refers to the DMRS in Physical Broadcast Channel (PBCH); the TRS can be the TRS in idle mode, the SSB1 can be the Cell-Defining SSB, and the SSB2 can be the Non-Cell-Defining SSB.

[0172] It should be noted that the identification information of at least one of the signals used for sensing measurement can also be defined by the protocol. For example, the configuration information of the first signal is indicated in other SIBs, such as the TRS in idle mode being indicated by the SIB; or, Table 4 above is defined by the protocol.

[0175] The CDM type mentioned above may include CDM values and modes, and the resource mapping mentioned above may include Orthogonal Frequency Division Multiplexing (OFDM) symbols and subcarrier occupancy information of resources within the time slot.
[0176] In addition, the configuration information of at least one of the signals used for sensing and measurement can also be pre-configured or agreed upon by a protocol.

[0178] Table 6:
[0179] index Reference signal or synchronization signal 1 RSRP 2 Doppler extension 3 AOA 4 …
[0180] In this context, AOA refers to the Angle of Arrival (AOA).
[0181] Furthermore, at least one of the aforementioned sensing measurement information can be agreed upon by protocol, for example, the protocol defines Table 5 above. Of course, Table 6 above is just a simple illustrative table.
[0182] The resource information for reporting at least one of the above-mentioned sensing measurements may include at least one of the time-domain resources and frequency-domain information for reporting sensing measurements, as well as the corresponding number or index.
[0183] The aforementioned terminal identification information may include at least one of the following:
[0184] Terminal grouping rules, terminal grouping identifiers, and terminal identifiers.
[0185] The aforementioned terminal group identifier may include a terminal group index identifier and associated terminal identifier features to identify the group to which the terminal belongs, and the terminals within that group. Using a terminal group identifier can save on the overhead of the terminal identifier. For example, the aforementioned terminal group identifier may be obtained by performing a certain operation, such as a hash function, on the terminal identifier.
[0186] The aforementioned terminal identifier may include the terminal core network identifier, such as the 5G globally unique temporary UE identity (5G-GUTI), the 5G shortened form-temporary mobile subscriber identity (5G-S-TMSI), the 5G shortened form-temporary mobile subscriber identity (5G-TMSI), the subscription concealed identifier (SUCI), etc.; or the aforementioned terminal identifier may include the terminal radio access network identifier, such as the inactive radio network temporary identifier (I-RNTI), the RAN UE NGAP ID, etc., wherein the RAN UE NGAP ID is an identifier sent by the base station to the AMF to identify the base station end connected to the control panel on the NG interface of the terminal.
