[0032] To enable those skilled in the art to better understand the embodiments of this application, the following description is provided first.
[0033] Communication and sensing integration refers to the integrated design of communication and sensing functions within the same system through spectrum sharing and hardware sharing. While transmitting information, the system can sense information such as location, distance, and speed, and detect, track, and identify target devices or events. The communication system and the sensing system complement each other, thereby improving overall performance and bringing a better service experience.
[0034] Future mobile communication systems, such as B5G or 6G systems, will possess sensing capabilities in addition to communication capabilities. Sensing capabilities refer to the ability of one or more devices to sense the location, distance, and speed of target objects through the transmission and reception of wireless signals, or to detect, track, identify, and image target objects, events, or environments. With the deployment of small base stations using high-frequency, high-bandwidth technologies such as millimeter waves and terahertz waves in 6G networks, the resolution of sensing will be significantly improved compared to centimeter waves, enabling 6G networks to provide more refined sensing services.
[0035] The integration of communication and radar is a typical application of communication-sensing fusion. In the past, radar systems and communication systems were strictly separated due to different research objects and focuses, and in most scenarios, the two systems were studied separately. In fact, radar and communication systems are both typical methods of information transmission, acquisition, processing, and exchange, and they share many similarities in terms of working principles, system architecture, and frequency bands. The design of integrated communication and radar is highly feasible, mainly in the following aspects: First, both communication and sensing systems are based on electromagnetic wave theory, using the transmission and reception of electromagnetic waves to complete information acquisition and transmission; second, both communication and sensing systems have structures such as antennas, transmitters, receivers, and signal processors, resulting in significant overlap in hardware resources; with technological advancements, their operating frequency bands also increasingly overlap; furthermore, they share similarities in key technologies such as signal modulation and 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, improved spectral efficiency, and reduced mutual interference, thereby improving the overall system performance.
[0036] Currently, there has been considerable research on the integrated design of radar and communication systems. Typical joint designs include spectrum coexistence, where the two systems operate independently, allowing information exchange to reduce mutual interference; receiver sharing, where the transmitting ends of the two systems send their own signal waveforms, and the waveforms of the two systems need to be orthogonal so as not to affect their respective reception and detection; transmitter sharing, where the transmitting end transmits a joint waveform of radar and communication; and transmitter-receiver sharing, where the transmitting and receiving ends of the two systems share resources, which also requires the use of joint waveforms or waveforms with orthogonal relationships.
[0037] Sensing can be conducted in two modes: single-site and multi-site. Single-site sensing transmits a sensing signal and receives and analyzes the echo signal to extract sensing parameters. For example, a base station acts as both the transmitter and receiver, while a terminal or other object acts as the sensing target. Alternatively, dual-site or multi-site sensing can be used. Single-site transmitting and receiving are not co-located; other receivers receive and analyze the signal to extract sensing parameters. For example, base station 1 acts as the transmitter, while a terminal or base station 2 acts as the receiver. Similarly, in single-site or multi-site sensing, the transmitter can also be a terminal.
[0038] The perception method provided in this application will be described in detail below with reference to the accompanying drawings and through some embodiments and application scenarios.
[0039] like Figure 2 As shown, this application provides a sensing method, including:
[0040] Step 201: The first terminal performs a sensing measurement and obtains the sensing measurement result. The first terminal is a terminal in an idle state or an inactive state.
[0041] Here, the first terminal can perform sensing measurements based on the received sensing signals to obtain the sensing measurement results.
[0042] The sensing signal in this application embodiment may specifically be a signal used to acquire information such as the orientation, distance, and speed of a target object, or a signal used to detect, track, identify, and image a target object, event, or environment.

[0056] The bandwidth of the sensing signal, which is inversely proportional to the distance resolution, can be obtained by c / (2*delta_d), where delta_d is the distance resolution (related to sensing requirements).
[0057] The burst duration of the sensed signal is inversely proportional to the rate resolution (which is a requirement for sensing). This parameter represents the time span of the sensed signal and is mainly used to calculate the Doppler frequency offset. This parameter can be calculated using c / (2*delta_v*fc), where delta_v is the rate resolution and fc is the center frequency of the signal.
[0058] The time-domain interval of the sensing signal can be calculated by c / (2*fc*v_range); where v_range is the maximum speed minus the minimum speed (related to sensing requirements); this parameter is the time interval between two adjacent sensing signals; and fc is the carrier frequency of the signal.

[0063] The frequency resources of the sensed signal include the center frequency, bandwidth, RB and / or subcarrier of the target signal;
[0064] The quasi-co-located QCL relationship of the sensed signal, for example, the target signal includes multiple resources, each resource is associated with an SSB QCL, and the QCL includes Type A, B, C or D;

[0104] Optionally, the first terminal performs sensing measurements, including:
[0105] The first terminal receives second indication information, the second indication information including a terminal identifier list, wherein the terminal identifier list corresponds to a terminal with sensing and measurement capabilities;
[0106] If the terminal identifier of the first terminal is included in the terminal identifier list, the first terminal performs sensing measurements.
[0107] In this embodiment of the application, the terminal identifier can be the identifier of a terminal group. The terminal identifier list can be determined by the network function or network element of the core network (such as the sensing network function or sensing network element). The first terminal matches its own ID with the ID in the terminal identifier list. If the ID of the first terminal is an ID in the list, it is determined to be a sensing associated terminal, and then sensing measurement is performed.
[0108] The aforementioned terminal identifier can be a terminal core network identifier, such as a 5G globally unique temporary UE identity (5G-GUTI), a 5G-S-temporary mobile subscriber identity (5G-S-TMSI), a 5G-TMSI, a Subscription Concealed Identifier (SUCI), etc., or it can be a UE radio access network identifier, such as an inactive radio network temporary identifier (I-RNTI), a RAN UE NG application protocol (NGAP) ID, etc.
[0109] Optionally, the terminal corresponding to the terminal identifier list is a terminal with a first sensing capability type, where the first sensing capability type is the sensing capability type corresponding to the sensing measurement.
[0110] In other words, the first sensing capability type mentioned above is the sensing capability type corresponding to this sensing service, such as the echo detection capability type.
[0111] Optionally, the first terminal reports the sensing measurement results, including:

[0114] The reporting time of the aforementioned sensing measurement results can be a time point, a reporting period, and / or the latest reporting time (associated with sensing QoS).
[0115] The reporting cycle for the aforementioned sensing measurement results can be the same as the DRX cycle, that is, the downlink sensing signal is sent by paging, and the result is reported after each measurement is completed upon receiving the paging signal.
[0116] Optionally, the method in this application embodiment further includes:
[0117] The amount of data reported for the sensing measurement results is related to the amount of data reported for the sensing measurement results.
[0118] The specific methods for reporting data volume may include at least one of the following:
[0119] The UE initiates SDT and reports it via MSG1 (either through a special preamble or through a special RO resource).
[0120] The UE initiates SDT and reports it via MSG3;
[0121] After the UE initiates SDT and sends an RRC resume request via MSG 3, a time window is opened. Within the time window, the UE can receive PUSCH scheduled by PDCCH and report via PUSCH.
[0122] The UE initiates random access and enters the connected state, reporting via PUCCH or PUSCH.
[0123] Here, the amount of data from the sensing measurement results is reported to the network device so that the network device can determine the appropriate reporting method for the sensing measurement results based on the amount of data.
[0124] Specifically, when the amount of data of the sensing measurement result is less than or equal to the first preset threshold, the sensing measurement result is reported in the first reporting method.
[0125] If the amount of data in the sensing measurement result is greater than a first preset threshold, the sensing measurement result is reported using a second reporting method.
[0126] The first reporting method is to report by initiating Small Data Transmission (SDT);
[0127] The second reporting method is to report by initiating random access.
[0128] In this embodiment of the application, when instructing to report in the first reporting method described above, it may also instruct SDT configuration or CG-SDT.
[0129] Among them, reporting through the first reporting method mentioned above includes:
[0130] Reporting via MSG1 (e.g., when the data volume is small, it is represented by a special preamble or by a special physical random access channel transmission opportunity RO resource representation);
[0131] Alternatively, the UE can initiate SDT and report via MSG3 or MSG A (or MSG2 can schedule more resources, schedule multiple PUSCH resources, and report via the scheduled PUSCH resources).
[0132] Alternatively, after sending the RRC resume request via MSG 3, the network side and / or the terminal open a time window (or timer). Within the time window, the UE can receive the PDCCH to schedule the PUSCH and report through the PUSCH.
[0133] The length of the time window, the size of the scheduled PUSCH resources (number of RBs, number of symbols) or the number of PUSCHs are related to the size of the sensing measurement result data. The size of the sensing measurement result data can be calculated by the core network functions or network elements (such as sensing network functions / sensing network elements) and / or the base station according to the sensing requirements, or it can be reported by the UE after completing the sensing measurement.
[0134] Among them, reporting through the second reporting method mentioned above includes:
[0135] The UE initiates random access and enters the connected state, reporting via PUCCH or PUSCH.
[0136] Optionally, when the UE initiates SDT or random access, MSG1 or MSG A contains target indication information.

[0141] System Information Block (SIB) messages, for example, target indication information that indicates some common sensing signals via SIB;
[0142] Radio Resource Control (RRC) release messages, for example, PDCCH carries a limited amount of information, so configuration can be considered in the RRC release message and activated through PDCCH (Paging PDCCH field size is limited, several sensing signal configuration types are agreed upon in advance, different sensing signal configuration types and corresponding specific configurations are issued by RRC release, and PDCCH uses fewer bits to indicate the sensing signal configuration type).
[0143] Messages during the random access procedure, including but not limited to Msg2, Msg4, and MsgB;
[0144] PDCCH scrambled with the temporary identifier C-RNTI of the cell wireless network;

[0146] Specifically, target indication information update indication can be carried in the PDCCH scrambled by C-RNTI, and target indication information can be carried in the PDSCH scheduled by the PDCCH.
[0147] It should be noted that the first instruction information, the second instruction information, and the third instruction information in the embodiments of this application can be sent through the same message or through different messages.
[0148] Optionally, the first terminal receives target indication information via the first PDCCH, including:
[0149] The first terminal receives target indication information based on the bit positions of the short message in the first PDCCH;
[0150] Alternatively, the first terminal receives target indication information based on the reserved bit in the first PDCCH;
[0151] Alternatively, the first terminal receives at least one first target PDCCH based on the target PDCCH information indicated by the first PDCCH, wherein the first target PDCCH carries the target indication information.

[0157] Optionally, the time interval between the first target PDCCH and the first PDCCH is defined by the protocol or configured by the network.
[0158] Specifically, the first target PDCCH reuses the control resource set (CORESET) or search space (SS) of the first PDCCH, or reuses a dedicated CORESET or SS of the first PDCCH. Optionally, the time interval (gap) between the first PDCCH and the first target PDCCH is agreed upon by the protocol or configured by the network, for example, 2ms.
[0159] Optionally, the first PDCCH is determined according to the indication of the second PDCCH.
[0160] In this embodiment, the second PDCCH can instruct the first terminal to receive at least one first PDCCH, and the PDSCH scheduled by the first PDCCH carries the aforementioned target indication information. In this method, coarse or stable information can be scheduled through the first-level DCI (the DCI in the second PDCCH), and the listening period of the first-level DCI can be set to be longer. More refined information can be scheduled through the second-level DCI (the DCI in the first PDCCH), effectively reducing the overhead of the PDCCH.
[0161] Optionally, the DCI of the first PDCCH mentioned above is DCI 1_0 scrambled using P-RNTI.
[0162] Optionally, the first terminal receives the target indication information via a first PDSCH scheduled by a first PDCCH, including:

[0165] Optionally, the carrying information includes at least one of the following:
[0166] Target indication information;
[0167] Paging message.
[0168] Optionally, obtaining the first information indicated by the first PDCCH includes:

[0171] Alternatively, the first information can be obtained based on the first RNTI, where the first RNTI is an RNTI that scrambles the first PDCCH;
[0172] Wherein, the first RNTI is associated with the sensing service, or the first RNTI is associated with both the sensing service and paging.
[0173] In this embodiment of the application, if the UE does not support sensing capability and receives a paging DCI, and the DCI is a sensing-related DCI, then the UE will not receive the PDSCH scheduled by the DCI.
[0174] Optionally, the terminal identifier list associated with sensing can reuse the UE ID list in the PDSCH of the DCI 1_0 schedule scrambled by P-RNTI. Optionally, the UE ID list in the PDSCH can be followed by an indication of whether the UE ID is associated with sensing, paging, or both.
