Description

Method and device for setting up a sensing group in a wireless communication system

[0001] The following description relates to a wireless communication system, and more particularly, to a device and method for setting a sensing group in a wireless communication system.

[0002] Wireless access systems are widely deployed to provide various types of communication services, such as voice and data. Typically, wireless access systems are multiple access systems that support communications with multiple users by sharing available system resources (e.g., bandwidth, transmission power). Examples of multiple access systems include code division multiple access (CDMA), frequency division multiple access (FDMA), time division multiple access (TDMA), orthogonal frequency division multiple access (OFDMA), and single-carrier frequency division multiple access (SC-FDMA).

[0003] In particular, as numerous communication devices demand greater communication capacity, enhanced mobile broadband (eMBB) communication technologies are being proposed, improving upon existing radio access technology (RAT). Furthermore, massive machine type communications (mMTC), which connects numerous devices and objects to provide diverse services anytime and anywhere, as well as communication systems that consider reliability and latency-sensitive services / user equipment (UE), are being proposed. Various technological configurations are being proposed for these purposes.

[0043] In the description of the drawings, procedures or steps that may obscure the gist of the present disclosure are not described, and procedures or steps that can be understood by a person skilled in the art are also not described.

[0044] Throughout the specification, when a part is said to "comprising" or "including" a component, this does not mean that other components may be included, but rather that other components may be excluded, unless otherwise specifically stated.

[0083]

[0084] 5G system architecture applicable to the present disclosure

[0085] The 5G system is an advanced technology from the 4th generation LTE mobile communication technology. It supports new radio access technology (RAT: Radio Access Technology), extended LTE (eLTE) as an extended technology of LTE (Long Term Evolution), and non-3GPP (e.g., WLAN) access through the evolution or clean-state structure of the existing mobile communication network structure.

[0086] 5G systems are defined as service-based, and the interactions between network functions (NFs) within the architecture for 5G systems can be expressed in two ways as follows.

[0087] - Reference point representation: Represents the interaction between NF services within NFs described by a point-to-point reference point (e.g., N11) between two NFs (e.g., AMF and SMF).

[0088] Service-based representation: Network functions (e.g., AMF) within the control plane (CP) allow other authorized network functions to access their services. This representation also includes point-to-point reference points, if necessary.

[0089] 5GC (5G Core) can include various components, some of which include access and mobility management function (AMF), session management function (SMF), policy control function (PCF), user plane function (UPF), application function (AF), unified data management (UDM), and non-3GPP interworking function (N3IWF).

[0090] The UE connects to the data network via the UPF via the next-generation radio access network (NG-RAN) that includes the gNB. The UE can receive data services via untrusted non-3GPP access points, such as wireless local area networks (WLANs). To connect non-3GPP access points to the core network, an N3IWF may be deployed.

[0091] The N3IWF manages interworking between non-3GPP access and 5G systems. When a UE is connected to a non-3GPP access (e.g., WiFi, also known as IEEE 802.11), it can connect to a 5G system via the N3IWF. The N3IWF performs control signaling with the AMF and connects to the UPF via the N3 interface for data transmission.

[0092] AMF can manage access and mobility in 5G systems. It can also manage non-access stratum (NAS) security. It can also handle mobility in idle states.

[0093] The UPF functions as a gateway for transmitting and receiving user data. A UPF node can perform all or part of the user plane functions of a 4G mobile communications S-GW (serving gateway) and P-GW (packet data network gateway).

[0094] The UPF acts as a boundary point between the next generation RAN (NG-RAN) and the core network, and is an element that maintains the data path between the gNB and the SMF. In addition, the UPF acts as a mobility anchor point when the UE moves across the area served by the gNB. The UPF can perform the function of handling PDUs. For mobility within the NG-RAN (e.g., NG-RAN defined after 3GPP Release-15), the UPF can route packets. In addition, the UPF can also act as an anchor point for mobility with other 3GPP networks (e.g., RAN defined before 3GPP Release-15), such as UTRAN (UMTS (universal mobile telecommunications system) terrestrial radio access network), E-UTRAN (evolved-UTRAN), or GERAN (GSM (global system for mobile communication) / EDGE (enhanced data rates for global evolution) radio access network). A UPF may correspond to the termination point of a data interface toward a data network.

[0095] The PCF is a node that controls the operator's policies. The AF is a server that provides various services to UEs. The UDM is a server that manages subscriber information, similar to the HSS (home subscriber server) of 4G mobile communications. The UDM (460) stores and manages subscriber information in a unified data repository (UDR).

[0096] The SMF can perform the function of assigning an IP (Internet protocol) address to the UE. In addition, the SMF can control the PDU (protocol data unit) session.

[0097] For convenience of explanation below, the drawing symbols for AMF, SMF, PCF, UPF, AF, UDM, N3IWF, gNB, or UE may be omitted, and operation may be performed by referring to the matters described in standard documents published prior to this document.

[0098] Figure 3 illustrates an example of functional separation of NG-RAN and 5GC (5th generation core) applicable to the present disclosure.

[0099] Referring to Figure 3, the UE connects to a data network (DN) via a next-generation RAN. The control plane function (CPF) node performs all or part of the functions of the mobility management entity (MME) of 4G mobile communications, and all or part of the control plane functions of the serving gateway (S-GW) and the PDN gateway (P-GW).

[0109] Specific embodiments of the present disclosure

[0110] The present disclosure relates to a device and method for dynamically setting up a sensing group in a wireless communication system. Specifically, the present disclosure relates to a method and device for dynamically setting up a sensing group by having a sensing initiator select at least one sensing group from among sensing groups preset in a network and join the selected at least one sensing group.

[0111]

[0112] Next-generation wireless communications are considered a key driver of diverse emerging fields, such as smart cities, industrial IoT, eHealth, automotive, public safety, and education. Sensing capabilities supporting these emerging applications are expected to play a critical role in meeting the demand for high-quality services based on the accuracy of environmental perception. Therefore, it is natural that sensing-related functions, technologies, and possibilities are being discussed in both cellular and WiFi networks.

[0113] Hereinafter, in the present disclosure, 5G wireless sensing may be defined as a 5GS function that provides the ability to obtain information about an environment and / or characteristics of objects within the environment (e.g., shape, size, direction, speed, position, distance, or relative movement between objects) using NR RF (radio frequency) signals, and in some cases, obtain predefined information available in EPC and / or E-UTRA. In addition, a sensing group may be defined as a set including at least one sensing transmitter and at least one sensing receiver whose location is known and capable of synchronously collecting sensing data. A sensing result may mean processed 3GPP sensing data requested by a service consumer, and a sensing signal may mean a transmitted signal on a 3GPP radio interface used for sensing. This definition refers to NR RF signals, and predefined information available in EPC and / or E-UTRA may be used to the extent that it does not affect the EPC and / or E-UTRA.

[0114] The present disclosure describes a sensing measurement process for collecting sensing measurement data. Sensing measurement data refers to data collected based on radio / wireless signals that are affected by, for example, reflection, refraction, or diffraction, by a target of interest or environment for sensing purposes. Hereinafter, sensing measurement data may be used and / or interpreted to indicate 3GPP sensing data and / or non-3GPP sensing data. Information derived from the sensing measurement data refers to sensing results. Furthermore, to clarify the sensing measurement process, four components are defined as follows: a sensing initiator, a sensing responder, a sensing transmitter, and a sensing receiver.

[0115] - Sensing initiator: An entity that starts the sensing measurement process, which may be a base station, a terminal, or a consumer premise equipment (CPE).

[0116] - Sensing responder: An entity that participates in the sensing measurement process in response to a sensing initiator, and may be a base station, a terminal, or a CPE.

[0117] - Sensing transmitter: An entity that transmits sensing signals to be used in the operation of a sensing service, which may be an NR RAN node or a terminal. The sensing transmitter may be the same entity as the sensing receiver or a different entity. In addition, the sensing transmitter may be a base station, terminal, or CPE that transmits sensing signals to be measured in the sensing measurement process.

[0118] - Sensing receiver: A sensing receiver is an entity that receives sensing signals to be used for the operation of a sensing service, and may be an RN RAN node or a terminal. The sensing receiver may be the same entity as the sensing transmitter or a different entity. In addition, the sensing receiver may be a base station, terminal, or CPE that receives sensing signals transmitted from the sensing transmitter and acquires sensing measurement data in the sensing measurement process.

[0119] In the present disclosure, a sensing initiator, a sensing responder, a sensing transmitter, and a sensing receiver may each be referred to as an initiator, a responder, a transmitter, and a receiver.

[0120] The location or service area for the sensing measurement process may include a target sensing service area and a moving target sensing service area. The target sensing service area refers to a Cartesian location area to be sensed by deriving characteristics of objects within the environment and / or environment having a specific sensing service quality from wireless signals affected (e.g., refraction, reflection, diffraction). Here, the target sensing service area may include both indoor and outdoor environments. In addition, the moving target sensing service area refers to a target sensing service area that moves according to the mobility of the target from the perspective of the sensing transmitter.

[0121] During a sensing measurement process, devices (e.g., base stations, terminals, or CPEs) may act as initiators, responders, transmitters, and / or receivers. As a sensing initiator, a device may initiate a sensing measurement process via a downlink shared channel (DSCH), a physical downlink control channel (PDCCH), a physical uplink shared channel (PUSCH), a physical uplink control channel (PUCCH), or a sidelink shared channel (SL-SCH). As a sensing initiator, a device that initiates a sensing measurement process may operate as at least one of a sensing transmitter and a sensing receiver, or may not operate as either a sensing transmitter or a sensing receiver. As a sensing initiator, a device may access sensing measurement data and transmit the sensing measurement data to a service provider or a service consumer via a network, or derive sensing results directly. As a sensing responder, a device may participate in the sensing measurement process via a PDSCH, a PDCCH, a PUSCH, a PUCCH, or a SL-SCH, and may perform the role of at least one of a sensing transmitter and a sensing receiver. The device acts as a sensing receiver and can access measurement data. The device acts as a sensing transmitter and can transmit sensing signals (e.g., channel state information reference signal (CSI-RS), CSI for interference management (CSI-IM), demodulation reference signal (DM-RS), phase tracking reference signal (PT-RS), sounding reference signal (SRS)) that are influenced by an object of interest or environment for sensing.If allowed, non-3GPP signals (e.g., radar signals) may be used as sensing signals. If high spectral efficiency is desired during the sensing measurement process, OFDM, discrete Fourier transform-spread-OFDM (DFT-S-OFDM), or variants thereof may be used as sensing signals. A device, acting as a sensing receiver, receives the affected sensing signals and, if necessary, reports sensing measurement data (e.g., PDSCH, PUSCH, SL-SCH, etc.) to a sensing initiator. A device acting as a sensing receiver has access to the sensing measurement data. Based on the topology or framework defined in 3GPP, the sensing initiator and the sensing transmitter may be the same device. Similarly, the sensing responder and the sensing receiver may be the same device.

[0122] FIG. 5 illustrates an example of a sensing measurement process according to the roles of devices applicable to the present disclosure, and FIG. 6 illustrates another example of a sensing measurement process according to the roles of devices applicable to the present disclosure.

[0123] Referring to FIG. 5, the base station (520) operates as a sensing initiator and a sensing transmitter, and the terminals (510-1, 510-2) operate as sensing responders and sensing receivers. At this time, the base station (520) sets up a sensing group with the terminals (510-1, 510-2) as sensing responders as a sensing initiator, and transmits a signal for sensing as a sensing transmitter. Each of the terminals (510-1, 510-2) receives a signal reflected by a target as a sensing receiver, and transmits sensing measurement data generated based on the received signal as a sensing result to the base station (520).

[0124] Referring to FIG. 6, the base station (620) operates as a sensing initiator and a sensing receiver, the first terminal (610-1) operates as a sensing responder and a sensing transmitter, and the second terminal (610-2) operates as a sensing responder and a sensing receiver. At this time, the base station (620) sets up a sensing group with the terminals (610-1, 610-2) that are sensing responders as a sensing initiator. Once the sensing group is set, the first terminal (610-1) transmits a signal for sensing as a sensing transmitter. The second terminal (610-2) and the base station (620) each receive a signal reflected by a target as a sensing receiver. The base station (620) stores sensing measurement data generated based on the received signal as a sensing result, and the second terminal (610-2) transmits sensing measurement data generated based on the received signal to the base station (620) as a sensing result.

[0125]

[0126] Figure 7 illustrates specific steps of a sensing measurement process applicable to the present disclosure. Referring to Figure 7, the sensing measurement process may be comprised of the following steps.

[0127] Sensing Group (SG) Setup Step (S701): The sensing group setup step (701) is a step in which a sensing initiator and a sensing responder form a sensing group. If necessary, updates to the sensing group can be performed. For example, an existing sensing group can be changed if necessary.

[0128] Sensing measurement configuration (SMC) setting step (S703): The sensing measurement configuration setting step (S703) is a step for setting information required for sensing measurement of a sensing transmitter and / or a sensing receiver within a sensing group, and if necessary, an update to the sensing measurement configuration can be performed.

[0129] Sensing measurement data (SMD) generation and reporting step (S705): The sensing measurement data generation and reporting step (S705) includes a sensing signal transmission step (S711) of a sensing transmitter, a sensing measurement data generation step (S713) of a sensing receiver, and a sensing measurement data reporting step (S715) of a sensing receiver.

[0130] Sensing measurement configuration end step (S707): The sensing measurement configuration end step (S707) is a step in which the sensing measurement configuration ends after the sensing measurement is completed.

[0131] Sensing group termination step (S709): The sensing group termination step (S709) is a step in which the sensing group is terminated after the sensing measurement configuration is terminated.

[0132] At least some of the steps of the sensing measurement process described above may be performed repeatedly. For example, the sensing measurement data generation and reporting step (S705) may be performed repeatedly. As another example, the sensing group setting step (S701) and the sensing measurement configuration setting step (S703) may be designed to be performed once. If necessary, at least one of the sensing group update or the sensing measurement configuration update may be performed repeatedly more than once. For example, the sensing measurement configuration setting step (S703) may be performed repeatedly to update the sensing measurement configuration.

[0133] When different devices are in different modes (e.g., sensing idle mode or sensing active mode) with respect to a sensing initiator, the sensing initiator may consider two conditions before starting a sensing measurement process. In the present disclosure, the idle mode and the active mode may be understood as a sensing idle mode for the sensing initiator and a sensing active mode for the sensing initiator, respectively. A terminal operating in idle mode with respect to sensing initiator A may operate in active mode with respect to another sensing initiator.

[0134] Depending on the different types of sensing measurement processes, during the idle mode of the sensing responder, each candidate responder or potential responder may periodically wake up and monitor to check if there is data to be received from the first sensing initiator. Alternatively, each candidate responder or potential responder may operate in a completely idle state with respect to the first sensing initiator so as not to expect data reception from the first sensing initiator while monitoring, measuring, or receiving data from a second sensing initiator that has completed the setup of another sensing group. That is, the sensing responder may operate in an idle mode with respect to the first initiator and in an active mode with respect to the second initiator or responder. While the candidate responder is in the active mode, the sensing initiator transmits information according to a predefined period, which may be conveyed via a control channel (e.g., PDCCH, SLCCH). At this time, the candidate responder participates in the sensing measurement process if the information indicates that there is data to be received. Assuming that active links have already been established between a sensing initiator and a sensing responder, the sensing initiator can obtain information corresponding to link quality, such as interference information and channel state information based on CSI-RS and CSI-IM, from potential responders. Before participating in the sensing measurement process, the initiator can perform a procedure to obtain link quality from the candidate responders. Information on when and where to switch to sensing active mode or the sensing active mode based on a specific pattern (e.g., duty cycle) can be configured semi-statically or dynamically by RRC, MAC CE, or DCI.

[0135]

[0136] Setting up sensing groups

[0137] A sensing initiator transmits sensing group setup request information, and the sensing group setup request information may include a first sensing group setup ID. The sensing group setup ID may be co-encoded with a portion of the setup request information (e.g., a CRC scrambled by the sensing group setup ID). The sensing group setup request information may include a minimum number of responders. The minimum number of responders may be configured by an RRC parameter (e.g., an RRC common parameter or an RRC UE-specific parameter). Subsequently, when a base station participates as a responder in a sensing measurement process, an RRC UE-specific parameter (e.g., an RRC responder / receiver parameter) for the base station may be used and / or interpreted. In this case, if a threshold value indicating the minimum number of responders is not defined, the minimum number of responders may be considered as 1 or a specific value. The sensing group setup request information may include capability information required for a sensing responder. The required capability information may be configured by an RRC parameter (e.g., an RRC common parameter or an RRC UE-specific parameter). The sensing group setup request information may remain the same until the sensing group is terminated by the sensing initiator or sensing responder. Parameters configured by RRC common parameters or RRC UE-specific parameters may remain the same until the sensing group is terminated by the initiator or responder.

[0138] A sensing responder transmits sensing group configuration response information in response to sensing group configuration request information including a first sensing group configuration ID. The sensing group configuration response information may be transmitted in the form of a first type of DCI. The first sensing group configuration ID may be CRC scrambled in the first type of DCI. The sensing group configuration response information may include information indicating a participation status of the responder. The participation status of the responder may include participation acceptance, participation rejection, or an adjustment status indicating that participation is possible under certain conditions. The sensing group configuration response information may be sensing group configuration-related information transmitted by a responder expected to withdraw or terminate a sensing group in which it is participating. When an adjustment status is received from a responder with certain conditions, a sensing initiator determines whether to accept the adjusted conditions.

[0139] If necessary, the sensing initiator verifies that the number of sensing respondents who wish to participate in the sensing group is greater than or equal to a first threshold. The first threshold can be set to a minimum number of respondents. The first threshold can be a fixed value or one of a predefined set of values. The predefined set can be set differently based on the environment or sensing object of interest for sensing. If there is no predefined threshold for the minimum number of respondents, the threshold can be considered as 1. As described above, when various values ​​are set in the first period, if the number of sensing respondents is less than the first threshold, the initiator waits until the longest value among the values ​​within the first period.

[0140] The sensing initiator transmits sensing group setup completion information having a first sensing group setup ID to one or more respondents that have responded with an acceptance or adjustment status. If the number of respondents is greater than or equal to the first threshold, the sensing initiator selects a responder to which to transmit the sensing group setup completion information.

[0141] - When negotiation for the corresponding link between the initiator and the responder is completed, sensing group setup completion information may be transmitted. At this time, the sensing group setup completion information may be transmitted from either the initiator or the responder.

[0142] - Sensing group setup completion information may be transmitted when all negotiations between the initiator and responder are completed. At this time, the initiator may transmit sensing group setup completion information when all negotiations between the initiator and responder are completed.

[0143] - Negotiations for establishing a sensing group between an initiator and a responder may be processed within a specific time interval. The specific time interval may be included in the first sensing group establishment request information with the first configuration ID. The specific time interval may be configured by an RRC common or RRC UE-specific parameter. Sensing group establishment completion information must be transmitted within the specific time interval.

[0144] The initiator completes the sensing group setup procedure and proceeds to the next step of the sensing measurement process with the respondent who completed the sensing group setup procedure.

[0145] To further configure the sensing group, the initiator can update responder-related information for the sensing group using the first sensing group configuration ID. One or more respondents may join or leave the sensing group for any reason. If the number of respondents is greater than or equal to the first threshold, the entire request-response-completion process described above may not be repeated.

[0146] - For additional work on sensing group configuration, sensing group configuration using the second sensing group configuration ID can be started before the sensing group configuration using the first sensing group configuration ID ends. In this case, one respondent can participate in more than one sensing group.

[0147] - If the number of respondents is less than the first threshold, the initiator proceeds to terminate the sensing group setup.

[0148]

[0149] Sensing Measurement Configuration Settings

[0150] After a successful sensing group setup, sensing measurement configuration setup is performed. Sensing measurement configuration setup begins by multicasting or unicasting sensing measurement configuration setup announcement information to users participating in the sensing group established during the sensing group setup phase.

[0151] The sensing measurement configuration setting notification information may include a sensing group setting ID. The sensing measurement configuration setting notification information may include a first sensing measurement configuration setting ID. The first sensing measurement configuration setting ID may be co-encoded with a portion of the sensing measurement configuration setting notification information (e.g., a CRC scrambled by the first sensing measurement configuration setting ID). Once a sensing measurement configuration setting ID is assigned to a sensing group, the notification information may remain the same until the corresponding sensing measurement configuration is terminated.

[0152] The sensing measurement configuration setting notification information may include the type of sensing measurement data to be measured. The sensing measurement data may be channel state information such as average SNR-related information, channel quality-related information, precoding matrix-related information, layer-related information, and / or rank-related information. The type of sensing measurement data may be configured by an RRC parameter (e.g., an RRC common parameter or an RRC UE-specific parameter). The type of sensing measurement data may be conveyed in the form of a first type of DCI. The first sensing measurement configuration setting ID may be CRC scrambled in the first type of DCI. Different sensing measurement data or different sets of sensing measurement data may be assigned different sensing measurement configuration setting IDs. For example, one sensing measurement data may be assigned one sensing measurement configuration setting ID. For example, one or more sensing measurement configuration setting IDs may be assigned to one or more sensing measurement data as a group. In addition, the sensing measurement data sets may be configured differently depending on the purpose. For example, for sensing measurement setup for sidelink, a subset of the sensing measurement data allocated to downlink may be required.

[0153] The sensing measurement configuration setting notification information may include information regarding the frequency at which sensing measurement data is generated. For example, a measurement interval may be set for each sensing measurement data, and different sensing measurement data may be measured at different intervals.

[0154] The sensing measurement configuration setting notification information may include the reporting frequency and / or content of sensing measurement data. For example, a reporting interval for each measurement data may be set, and different sensing measurement data may be reported at different intervals. When sensing measurement data is reported, the sensing measurement data may be the most recently measured sensing measurement data. The reported sensing measurement data may include an average value of one or more sensing measurement data.

[0155] Upon receiving the sensing measurement configuration setup notification information, a responder who participated in the sensing measurement process during the sensing group setup can transmit sensing measurement configuration setup completion information in response to the sensing measurement configuration setup notification information.

[0156] The initiator can verify whether the responder has accurately received the sensing measurement configuration information. The responder's transmission of sensing measurement configuration completion information indicates that the parameters configured for the sensing measurement set by the initiator have been accepted by the responder.

[0157] - The sensing measurement configuration setting response information may include information indicating at least one of an acceptance state, a rejection state, or an adjustment state. The sensing measurement configuration setting response information may be transmitted in a third type of DCI format. The first sensing measurement configuration setting ID may be CRC scrambled in the third type of DCI format. The acceptance state is a state indicating that the parameters configured for the sensing measurement set by the initiator have been accepted, and the rejection state is a state indicating that the parameters configured for the sensing measurement set by the initiator have been rejected. In addition, the adjustment state is a state indicating negotiation of the parameters configured for the sensing measurement set by the initiator. Here, for better recognition in a mobility situation, one or more parameters for the sensing measurement may be proposed by the responder through the sensing measurement configuration setting response information.

[0158] - The initiator can transmit sensing measurement configuration setup completion information to one or more responders. For example, transmitting sensing measurement configuration setup completion information to a responder in an accepting state means that the initiator has confirmed that the configured parameters for the sensing measurement set by the initiator have been accepted by the responder. As another example, transmitting sensing measurement configuration setup completion information to a responder in an adjusting state means that the initiator has accepted the configured parameters for the sensing measurement set by the responder. Alternatively, transmitting sensing measurement configuration setup completion information to a responder in a rejecting state means that the initiator has confirmed that the responder has rejected the configured parameters for the sensing measurement set by the initiator and has not proposed any configuration parameters. In order to save resources, the initiator may not transmit sensing measurement configuration setup completion information to a responder in a rejecting state.

[0159] Additional negotiations may be performed between the initiator and responder to set configuration parameters for the sensing measurements.

[0160] - Sensing measurement configuration setup completion information may be transmitted when negotiation for each corresponding link between the initiator and responder is completed. Sensing measurement configuration setup completion information may be transmitted from either the initiator or the responder.

[0161] - Sensing measurement configuration setup completion information can be transmitted when all negotiations between the initiator and the responder are completed. The initiator can transmit sensing measurement configuration setup completion information when all negotiations between the initiator and the responder are completed.

[0162] To further configure the sensing measurement configuration, the initiator may update information related to the sensing measurement configuration. The measurement time interval of one or more sensing measurement configurations for the sensing measurement data may be updated to a new measurement time interval. At this time, the remaining configurations for the sensing measurement data remain the same. The reporting time interval of one or more sensing measurement configurations for the sensing measurement data may be updated to a new reporting time interval. At this time, the remaining configurations for the sensing measurement data remain the same.

[0163] For additional sensing measurement tasks, a sensing measurement configuration setup using a second sensing measurement configuration setup ID may be initiated before the end of a sensing measurement using the first sensing measurement configuration setup ID. A responder may participate in more than one sensing measurement configuration setup.

[0164]

[0165] Generation and reporting of sensing measurement data

[0166] After the sensing measurement configuration setup is successfully performed, sensing measurement data generation and reporting are performed. Some steps in the sensing measurement process, namely the sensing measurement data generation and reporting steps, may be repeated as illustrated in FIG. 7.

[0167] Once the sensing group setup and sensing measurement configuration are complete, the transmitter transmits a sensing signal. Furthermore, two or more transmitters can transmit the sensing signal. The receiver or initiator can trigger one or more transmitters to transmit the sensing signal. The receiver measures and reports the transmitted sensing signal according to the configuration preset during the sensing measurement configuration setup.

[0168] An exemplary signaling for sensing measurement configuration settings and sensing measurement data generation and reporting is illustrated in FIG. 8. FIG. 8 illustrates an example of a sensing measurement data generation and reporting procedure based on a sensing measurement configuration applicable to the present disclosure. Each of the transmitter (820) and / or receivers (810-1, 810-2, 810-3) illustrated in FIG. 8 may be a terminal, a base station, or another network entity. For example, the transmitter (820) may be a base station, and the receivers (810-1, 810-2, 810-3) may be terminals. The transmitter (820) may be an initiator, and the first receiver (810-1), the second receiver (810-2), and / or the third receiver (810-3) may be potential or determined responders. The transmitter (820) may perform a sensing group configuration step (S801) that configures a sensing group with the first receiver (810-1). Once the sensing group configuration is completed, the transmitter (820) and the first receiver (810-1) participate in the sensing measurement process. That is, the transmitter (820) and the first receiver (810-1) may repeatedly perform the sensing measurement configuration configuration configuration steps (S803, S807, S811) and the sensing measurement data generation and reporting steps (S805, S809, S813). After the sensing measurement data generation and reporting are successfully performed, the sensing measurement configuration termination or the sensing group termination may be performed. Generally, the termination may be performed explicitly or implicitly by the initiator or the responder.

[0169]

[0170] End sensing measurement configuration

[0171] The termination of a sensing measurement configuration can be performed implicitly or explicitly. For example, the termination of a sensing measurement configuration can be performed implicitly after a predefined period of time to wait for expected information, or explicitly by first information indicating the termination of a sensing measurement configuration. The first information can include at least one of a sensing measurement configuration setting ID and a sensing group setting ID. In this case, the same sensing measurement configuration setting ID and different sensing group IDs can be assigned. The sensing measurement configuration can be terminated simultaneously for all participants in a sensing group by an initiator. The initiator can terminate one or more sensing measurement configurations for one or more specific respondents. One or more respondents can terminate their own sensing measurement configurations. The first information can include a sensing measurement configuration setting ID set to a specific value (e.g., F) to indicate the termination of all sensing measurement configurations regardless of the sensing measurement configuration setting ID.

[0172]

[0173] Sensing group termination

[0174] Sensing group termination can be performed implicitly or explicitly. For example, sensing group termination can be performed implicitly after a predefined period of time to wait for expected information, or can be performed by first information indicating the termination of the sensing group. The predefined period can be configured by an RRC common parameter or an RRC UE-specific parameter. The first information can include a sensing group configuration ID. A sensing group can be terminated simultaneously for all participants by an initiator. The initiator can terminate one or more sensing groups for one or more specific responders. One or more responders can terminate their own sensing groups. When a sensing group with a sensing group ID (SGID) set to A is terminated, the sensing measurement configuration with the SGID set to A is implicitly terminated. The first information can include a sensing group configuration ID set to a specific value (e.g., F) to indicate the termination of all sensing groups regardless of their corresponding sensing group configuration IDs.

[0175]

[0176] In 3GPP, DCI (Downlink Control Information) can convey information such as HARQ (hybrid automatic repeat and request) information for uplink and downlink, physical layer resource allocation, and power control commands.

[0177] - Information transmission for resource scheduling for PDSCH

[0178] - Information transfer for resource scheduling for PUSCH

[0179] - Information transmission for PUSCH and PUCCH power adjustment for UL power control

[0180] DCI is transmitted via the PDCCH with a 24-bit CRC. Multiple DCI formats are defined to meet various requirements and conditions, and NR DCI formats can share the same DCI size for efficient implementation.

[0181] In 3GPP, PUCCH is an uplink physical channel that carries uplink control information (UCI). DCI is carried by the PDCCH, and UCI is carried by the PUCCH. The major difference between DCI and UCI is that UCI can be transmitted on either the PUCCH or the PUSCH, depending on the situation, whereas DCI can only be transmitted on the PDCCH. DCI is never transmitted on the PDSCH. UCI is reported to the network through the uplink physical channel, PUCCH or PUSCH. UCI can include at least one of HARQ ACK / NACK, SR (scheduling request), or CSI. For example, UCI can include only one of HARQ ACK / NACK, SR, or CSI, or at least two of HARQ ACK / NACK, SR, or CSI, depending on the situation. HARQ ACK / NACK, SR, or CSI are not carried solely by a single UCI. UCI is encoded and transmitted over the PUCCH or multiplexed over the PUSCH. CSI reporting can be performed aperiodically over the PUSCH, periodically over the PUCCH, or semi-permanently over the PUCCH or DCI-activated PUSCH.

[0182] In the present disclosure, newly defined or modified information related to the sensing measurement process, for example, SGID, SMID, SMI, or sensing measurement data related information, may be carried via PUCCH and / or PUSCH together with the UCI as described above.

[0183] 3GPP has not yet discussed how a sensing initiator in a sensing system configures a sensing group (e.g., a sensing group including a responder) to initiate a sensing measurement process. Therefore, the present disclosure proposes a method for configuring a sensing group to initiate a sensing measurement process, wherein a base station, a network node, and / or a service provider preconfigures sensing groups, i.e., a set of sensing groups. Specifically, the present disclosure proposes a method and apparatus in which a base station, a network node, and / or a service provider preconfigures a set of sensing groups, and a sensing initiator selects at least one sensing group from the preconfigured set of sensing groups to perform a sensing measurement process.

[0184] A pre-configured set of sensing groups may include N sensing groups. Each sensing group may include one or more initiators and / or one or more responders. If a set of sensing groups is pre-configured, the initiator does not need to perform additional processes to configure the sensing groups or to find devices to be included in the sensing groups to initiate the sensing measurement process. For example, the initiator may select at least one sensing group from the pre-configured sensing groups based on some criteria, conditions, or circumstances. In this way, the sensing measurement process can be performed simply and efficiently.

[0185] Each sensing group within a sensing group set may be assigned an index. For example, a first sensing group may be assigned a first index, and a second sensing group may be assigned a second index. The index assigned to each sensing group may be used as an ID of the sensing group. The sensing groups to which the indexes are assigned may be known or exposed to the initiator and / or the responder when the sensing group set is configured. The sensing group set may be configured by RRC, and some parameters need to be defined for the sensing measurement process.

[0186] According to the prior art, a sensing initiator must request at least one other device (e.g., a responder) to configure a sensing group for itself. In contrast, according to one embodiment of the present disclosure, a sensing initiator can participate in at least one selected sensing group by selecting at least one sensing group from a pre-configured set of sensing groups without requesting the configuration of a sensing group from at least one other device. Here, participating in a sensing group may include performing an authentication procedure on the sensing initiator.

[0187] In order for the initiator to dynamically indicate a sensing group, an existing or new type of DCI and / or UCI for the sensing measurement process may include an index of at least one sensing group from a configured set of sensing groups. In a multi-cell or multi-band environment, a dedicated type of DCI and / or UCI for the sensing measurement process may be used. Alternatively, a MAC CE may convey an index of at least one sensing group from a configured set of sensing groups for dynamic indication.

[0188] A predefined or configured sensing group set at a specific point in time, during a specific period, or during a time interval may be reset for any reason. That is, a new sensing group set may be created and configured. In one embodiment, the sensing group set may be reset based on an RRC configuration parameter, such as a specific period. In one embodiment, the sensing group set may be reset aperiodically based on an event triggered by a specific condition. Here, the event may be designated as a condition, and when the condition for the event is met, a new sensing group set is configured. For example, the condition may be a degradation of sensing performance over a specific period of time (e.g., a degradation ratio), a high percentage of sensing groups smaller than a first threshold, or when members of the current sensing group are evaluated as being outside the cell, outside the service area, or outside the service period.

[0189] When information about a new set of sensing groups is received by a device belonging to a particular sensing group, a particular sensing group included in the outdated set of sensing groups may be terminated.

[0190] There are several options for creating a set of sensing groups. Here, the concept of a set is used to associate a device with at least one sensing group among the sensing groups already existing and exposed or identified in the device. The device uses the set of sensing groups to select the most suitable candidate sensing group for association, and the device can obtain sensing-related data or sensing services through association with the selected sensing group.

[0191]

[0192] FIG. 9 illustrates an example of a sensing group set according to one embodiment of the present disclosure.

[0193] Referring to FIG. 9, a responder may belong to at least one sensing group among a plurality of sensing groups included in a sensing group set. That is, a device operating as a responder may be linked to at least one sensing group among a plurality of sensing groups. Here, the device may be a base station or a terminal. For example, a sensing group set may include N sensing groups (901, 902, 903, 904), and responder B may belong to sensing group 1 (901), sensing group 2 (902), and sensing group 3 (903) among the N sensing groups. For example, sensing group 1 (901) may include responder A and responder B, and sensing group 2 (902) may include responder B, responder C, and responder D. In addition, sensing group 3 (903) may include responder B and responder E, and sensing group N (904) may include responder F and responder G. The configuration of such sensing groups is only an example to aid understanding, and the present disclosure is not limited thereto.

[0194]

[0195] FIG. 10 illustrates another example of a sensing group set according to an embodiment of the present disclosure. Referring to FIG. 10, a responder can belong to only one sensing group among multiple sensing groups included in a sensing group set. That is, one responder cannot be included in multiple different sensing groups. In other words, if a first device acting as a responder belongs to one sensing group, the first device cannot belong to another sensing group. Here, the first device may be a base station or a terminal. For example, a sensing group set may include N sensing groups (1001, 1002, 1003), and responders A and B may belong only to sensing group A (1001). As an example, sensing group 1 (1001) may include responders A and B, and sensing group 2 (1002) may include responders C and D. In addition, sensing group N (1003) may include responders E, F, and G. The configuration of such sensing groups is only an example to aid understanding, and the present disclosure is not limited thereto.

[0196]

[0197] FIG. 11 illustrates another example of a sensing group set according to one embodiment of the present disclosure. Referring to FIG. 11, an initiator and / or a responder may belong to at least one sensing group among a plurality of sensing groups included in the sensing group set. For example, the sensing group set may include N sensing groups (1101, 1102, 1103, 1104, 1105), and initiator B and responder B may belong to all of sensing group 1 (1101), sensing group 2 (1102), and sensing group 3 (1103). As an example, sensing group 1 (1101) may include initiator A, initiator B, responder A, and responder B, and sensing group 2 (1102) may include initiator B, responder B, responder C, and responder D. Additionally, sensing group 3 (1103) may include initiator B, responder B, and responder E, sensing group 4 (1104) may include responder H and responder I, and sensing group N (1105) may include initiator C, responder F, and responder G. The configuration of such sensing groups is merely an example to aid understanding, and the present disclosure is not limited thereto.

[0198]

[0199] FIG. 12 illustrates another example of a sensing group set according to one embodiment of the present disclosure. Referring to FIG. 12, an initiator and / or a responder may belong to only one group among a plurality of sensing groups included in a sensing group set. An initiator or a responder is not included in different sensing groups. For example, a sensing group set may include N sensing groups (1201, 1202, 1203), and initiator A and responder B may belong only to sensing group 1 (1201). For example, sensing group 1 (1201) may include initiator A, responder A, and responder B, and sensing group 2 (1202) may include initiator C, initiator G, responder C, and responder D. In addition, sensing group N (1203) may include initiator B, responder E, responder F, and responder G. The configuration of such sensing groups is only an example to aid understanding, and the present disclosure is not limited thereto.

[0200]

[0201] As described with reference to FIGS. 9 to 12, a sensing system and / or a network node for a sensing service presets a set of sensing groups, and each device (e.g., a base station or a terminal) having a function of supporting a sensing measurement process can know at least one sensing group to which it belongs. Each device can identify the sensing group to which it belongs by obtaining information (e.g., a sensing group index) about at least one sensing group from the network node. For example, as illustrated in FIG. 9, respondent B can know that it belongs to sensing group 1, sensing group 2, and sensing group 3. In addition, the initiator can recognize the size of each sensing group, the respondent's capability, and / or exposure information within the sensing group. The exposure information may include information about an exposure scenario that is distinguished according to the amount and / or type of information to be exposed. When the initiator is given the aforementioned information from each sensing group, the initiator can select at least one sensing group to which it belongs, based on the given information, to perform a sensing measurement process.

[0202]

[0203] In the present disclosure, information about sensing groups of terminals and / or base stations may be exposed to the sensing initiator. The information about the sensing groups exposed may vary depending on exposure scenario 1 or exposure scenario 2. Furthermore, the members (e.g., respondents) of each sensing group may vary based on the exposure information.

[0204] According to Exposure Scenario #1, the existence of a sensing group may be disclosed by exposing the index of each sensing group within the sensing group set. How the sensing system and / or sensing service arranges the members (e.g., responders) of each sensing group may vary depending on the implementation. When selecting a sensing group, the initiator may only have limited information, such as the size of each sensing group, and may not have any additional information.

[0205] On the other hand, additional information about each sensing group may be exposed according to Exposure Scenario #2. For example, according to Exposure Scenario #2, the exposure information may include information such as the number of members of the sensing group, information about the geographic location / area covered by the sensing group, information about the target sensing service area, information about the moving target sensing service area, and / or information about the members (e.g., subscriber information). According to Exposure Scenario #2, by exposing additional information about each sensing group as described above, it may be helpful for the initiator to select one or more sensing groups from the set of sensing groups.

[0206] The following steps can be taken to set up sensing groups based on exposure information:

[0207] 1. Network nodes and / or base stations evaluate the intent / preference of each sensing group near the sensing initiator to associate with the sensing initiator. Intention / preference may be evaluated based on exposure information.

[0208] 2. The network node and / or base station transmits the evaluated intent / preference information for each sensing group to the sensing initiator.

[0209] 3. The sensing initiator selects at least one sensing group from a set of sensing groups based on the intent / preference information.

[0210]

[0211] When selecting a sensing group, target sensing service area information and / or moving target sensing service area information can serve as important information. However, target sensing service area information and / or moving target sensing service area information are not necessarily provided as exposure information. Therefore, measures need to be taken to address such cases. For example, when a sensing group set is formed, at least one of the target sensing service area information or moving target sensing service area information for each sensing group needs to be configured to be provided as exposure information.

[0212]

[0213] Considering the sensing measurement process, a minimum number of respondents can be established to meet certain conditions during the sensing measurement process. This minimum number of respondents can be referred to as a first threshold. At least one sensing group (e.g., a sensing group set) can be predefined, configured, or directed for a specific initiator or responder. The present disclosure proposes several options for the sensing group selection procedure and corresponding signals.

[0214]

[0215] FIG. 13 illustrates an example of a sensing group set according to one embodiment of the present disclosure. Specifically, FIG. 13 illustrates a sensing group set (1301) from the initiator's perspective and a sensing group set (1303) from the respondent B's perspective. At least one of the steps described with reference to FIG. 13 may not be performed, or the order of at least one of the steps may be changed.

[0216] Referring to FIG. 13, each of the plurality of sensing groups included in the sensing group set may be configured to include at least one responder. At this time, at least one responder may belong to at least one sensing group. On the other hand, the initiator does not belong to any of the plurality of sensing groups included in the sensing group set. In this case, the initiator may select any sensing group within the sensing group set. However, since the initiator must be provided with exposure information for the entire sensing group set, relatively large resources are required. Alternatively, depending on the sensing system, only certain sensing groups may be provided or exposed to the initiator so that the initiator can efficiently select the optimal sensing group based on a limited number of potential sensing groups and the corresponding exposure information. From the responder's perspective, respondent B may belong to sensing group 1, sensing group 2, and sensing group 3, and exposure information for each sensing group may be provided. Alternatively, the responder may be provided with only a sensing group ID number without exposure information.

[0217] Step 1: A set of sensing groups is configured as shown in Fig. 13, and an index is assigned to each sensing group.

[0218] Step 2: The initiator performs an authentication procedure to select at least one sensing group.

[0219] Step 3: The initiator selects at least one sensing group from a set of sensing groups based on various levels of exposure information and instructs potential respondents within the selected sensing group to begin the sensing measurement process.

[0220] - The initiator can select one or more sensing groups whose size is greater than or equal to a first threshold value.

[0221] - The initiator may terminate the sensing group if it is determined that the number of respondents reporting sensing measurement data during the sensing measurement process is less than the first threshold value.

[0222] Step 4: If at least one of target sensing service area information or moving target sensing service area information does not exist in the exposure information, when a set of sensing groups is configured, target sensing service area information and / or moving target sensing service area information is generated as exposure information.

[0223] When a new initiator wishes to participate in the sensing measurement process, it requires information about the configured sensing group set. The new initiator can wait to obtain this information, which is periodically configured. Alternatively, the new initiator can send a request for information that triggers an event to trigger the information to be configured.

[0224] If a new responder wishes to participate in the sensing measurement process, the new responder must belong to a new sensing group set. The new responder can submit a request to join one or more sensing groups within the new sensing group set. Once the new sensing group set is formed, the new responder can be included as a member in one or more sensing groups with one or more indices.

[0225]

[0226] FIG. 14 illustrates another example of a sensing group set according to one embodiment of the present disclosure. Specifically, FIG. 14 illustrates a sensing group set (1401) from the perspective of the initiator and a sensing group set (1403) from the perspective of the responder B. At least one of the steps described with reference to FIG. 14 may not be performed, or the order of at least one of the steps may be changed.

[0227] Referring to Fig. 14, each of the plurality of sensing groups included in the sensing group set is configured to include at least one responder. In this case, each responder can belong to only one sensing group. On the other hand, the initiator does not belong to any of the plurality of sensing groups within the sensing group set. In this case, the initiator can select any of the plurality of sensing groups within the sensing group set. However, since the initiator must be provided with exposure information for the entire sensing group set, relatively large resources are required. Alternatively, depending on the sensing system, only certain sensing groups may be provided or exposed to the initiator so that the initiator can efficiently select the optimal sensing group based on a limited number of potential sensing groups and the corresponding exposure information. From the responder's perspective, respondent B may belong to only one sensing group (e.g., sensing group 1) among the sensing group sets, and exposure information for that sensing group may be provided. Alternatively, the responder may only need a sensing group ID number without exposure information.

[0228] Step 1: A set of sensing groups is configured as shown in Fig. 14, and an index is assigned to each sensing group.

[0229] Step 2: The initiator performs an authentication procedure to select one sensing group.

[0230] Step 3: The initiator selects one sensing group from a set of sensing groups based on various levels of exposure information and instructs potential respondents within the selected sensing group to begin the sensing measurement process.

[0231] - The initiator can select one sensing group whose size is greater than or equal to the first threshold value.

[0232] - The initiator may terminate the sensing group if it is determined that the number of respondents reporting sensing measurement data during the sensing measurement process is less than the first threshold value.

[0233] Step 4: If at least one of target sensing service area information or moving target sensing service area information does not exist in the exposure information, when a set of sensing groups is configured, target sensing service area information and / or moving target sensing service area information is generated as exposure information.

[0234] When a new initiator wishes to participate in the sensing measurement process, it requires information about the configured sensing group set. The new initiator can wait to obtain this information, which is periodically configured. Alternatively, the new initiator can send a request for information that triggers an event to trigger the information to be configured.

[0235] If a new responder wishes to participate in the sensing measurement process, the new responder must belong to a new sensing group set. The new responder can submit a request to join one sensing group within the new sensing group set. Once the new sensing group set is formed, the new responder can be included as a member of one sensing group with one or more indices.

[0236]

[0237] FIG. 15 illustrates another example of a sensing group set according to one embodiment of the present disclosure. Specifically, FIG. 15 illustrates a sensing group set (1501) from the perspective of initiator B and a sensing group set (1503) from the perspective of responder B. At least one of the steps described with reference to FIG. 13 may not be performed, or the order of at least one of the steps may be changed.

[0238] Referring to FIG. 15, each of a plurality of sensing groups included in a sensing group set may be configured to include at least one initiator and at least one responder. At this time, at least one initiator and / or at least one responder may belong to at least one sensing group. Accordingly, the initiator may belong to at least one sensing group among the plurality of sensing groups within the sensing group set. If each initiator is given a limited number of sensing groups, the initiator can efficiently select an optimal sensing group based on the limited number of potential sensing groups and the corresponding exposure information. For example, initiator B belongs to all of sensing groups 1, 2, and 3, and thus may select at least one sensing group among sensing groups 1, 2, and 3. From the responder's perspective, the responder belongs to at least one sensing group among the sensing group set. For example, responder B belongs to sensing group 1, sensing group 2, and sensing group 3, and exposure information for each group may be exposed. Alternatively, the responder may only need a sensing group ID number without exposure information.

[0239] Step 1: A set of sensing groups is configured as shown in Fig. 15, and an index is assigned to each sensing group.

[0240] Step 2: The initiator performs an authentication procedure to select at least one sensing group from among the sensing groups that include the sensing initiator.

[0241] Step 3: The initiator selects one or more sensing groups from a set of sensing groups containing the initiator based on various levels of exposure information.

[0242] Step 4: If at least one of target sensing service area information or moving target sensing service area information does not exist in the exposure information, when a set of sensing groups is configured, target sensing service area information and / or moving target sensing service area information is generated as exposure information.

[0243] Step 5: The initiator instructs potential respondents within the selected sensing group to begin the sensing measurement process.

[0244] - The initiator can select one or more sensing groups whose size is greater than or equal to a first threshold value.

[0245] - The initiator may terminate the sensing group if it is determined that the number of respondents reporting sensing measurement data during the sensing measurement process is less than the first threshold value.

[0246] When a new initiator wishes to participate in the sensing measurement process, it requires information about the configured sensing group set. The new initiator can send a request to join one or more sensing groups within the new sensing group set. Once the new sensing group set is configured, the new initiator can be included as a member in one or more sensing groups with one or more indices.

[0247] If a new responder wishes to participate in the sensing measurement process, the new responder must belong to a new sensing group set. The new responder can submit a request to join one or more sensing groups within the new sensing group set. Once the new sensing group set is formed, the new responder can be included as a member in one or more sensing groups with one or more indices.

[0248]

[0249] FIG. 16 illustrates another example of a sensing group set according to one embodiment of the present disclosure. Specifically, FIG. 16 illustrates a sensing group set (1601) from the perspective of initiator A and a sensing group set (1603) from the perspective of responder B. At least one of the steps described with reference to FIG. 16 may not be performed, or the order of at least one of the steps may be changed.

[0250] Referring to FIG. 16, each of a plurality of sensing groups included in a sensing group set may be configured to include at least one initiator and at least one responder. At this time, the initiator and / or the responder may belong to only one sensing group. Accordingly, the initiator may belong to only one sensing group among the sensing group sets. If only one sensing group is given to each initiator, the initiator can efficiently select the optimal sensing group. If exposure information for one sensing group exists, the optimal sensing group may be selected based on the exposure information. From the responder's perspective, the responder belongs to only one sensing group among the sensing group sets. For example, responder B belongs to only sensing group 1, and exposure information for sensing group 1 may be exposed. Alternatively, as a responder, only a sensing group ID number may be required without exposure information.

[0251] Step 1: A set of sensing groups is configured as shown in Fig. 16, and an index is assigned to each sensing group.

[0252] Step 2: The initiator selects one sensing group containing the initiator based on different levels of exposure information.

[0253] Step 3: If at least one of target sensing service area information or moving target sensing service area information does not exist in the exposure information, when a set of sensing groups is configured, target sensing service area information and / or moving target sensing service area information is generated as exposure information.

[0254] Step 4: The initiator instructs potential respondents within the selected sensing group to begin the sensing measurement process.

[0255] - The initiator can select one or more sensing groups whose size is greater than or equal to a first threshold value.

[0256] - The initiator may terminate the sensing group if it is determined that the number of respondents reporting sensing measurement data during the sensing measurement process is less than the first threshold value.

[0257] When a new initiator wishes to participate in the sensing measurement process, it requires information about the configured sensing group set. The new initiator can send a request to join one or more sensing groups within the new sensing group set. Once the new sensing group set is configured, the new initiator can be included as a member in one or more sensing groups with one or more indices.

[0258] If a new responder wishes to participate in the sensing measurement process, the new responder must belong to a new sensing group set. The new responder can submit a request to join one or more sensing groups within the new sensing group set. Once the new sensing group set is formed, the new responder can be included as a member in one or more sensing groups with one or more indices.

[0259]

[0260] FIG. 17 illustrates an example of an information reception procedure for sensing measurement according to one embodiment of the present disclosure. FIG. 17 illustrates a method performed by a first device. The first device may be a terminal.

[0261] Referring to FIG. 17, at step S1701, a first device receives a capability information request. The device may receive a message requesting transmission of terminal capability information from a second device. The second device may be a base station or a network node.

[0262] In step S1703, the first device transmits capability information of the first device. The capability information may include capability information related to the sensing service. For example, the capability information related to the sensing service may include at least one of information indicating whether the first device supports the sensing service, information on the first device's computational capabilities, or the types of raw data that the first device can process.

[0263] In step S1705, the first device receives control information or configuration information. In other words, the first device can receive control information or configuration information for a sensing service from the second device. The control information or configuration information for the sensing service may include sensing-related information for at least one sensing group among a plurality of preset sensing groups. For example, the control information or configuration information may include sensing-related information only for at least one sensing group to which the first device belongs, or may include sensing-related information for all of the plurality of sensing groups. The sensing-related information may include at least one of identification information (e.g., an index or ID) of the sensing group or exposure information of the sensing group. In this case, the exposure information may be configured differently depending on the exposure scenario.

[0264] In step S1707, the first device sets a sensing group based on control information or configuration information. In other words, the first device selects at least one sensing group for performing a sensing measurement process based on the control information or configuration information, and can perform a sensing function with at least one other device included in the at least one selected sensing group. The first device can perform the sensing measurement process with at least one member of the sensing group by transmitting information instructing the start of the sensing measurement process to at least one member (e.g., a potential responder) within the at least one selected sensing group.

[0265]

[0266] Figure 18 illustrates an example of an information transmission procedure for sensing measurements according to one embodiment of the present disclosure. Figure 18 illustrates a method performed by a second device. The second device may be a network node or a base station.

[0267] Referring to FIG. 18, in step S1801, the second device transmits a capability information request. The device may transmit a message requesting transmission of capability information to the first device.

[0268] In step S1803, the second device receives capability information. That is, the second device receives capability information from the first device. The capability information may include capability information related to a sensing service. For example, the capability information related to a sensing service may include at least one of information indicating whether the first device supports the sensing service, information on the first device's computational capabilities, or the types of raw data that the first device can process.

[0269] In step S1805, the second device generates control information or setting information based on the capability information. In other words, the second device can generate control information or setting information for a sensing service based on the capability information of the first device. The second device can set a sensing group set as described with reference to FIGS. 9 to 12 based on the capability information of the first device, and generate control information or setting information including information on the set sensing group set. The information on the sensing group set can include at least one of identification information (e.g., an index or a sensing group ID) of a sensing group to which the device belongs, exposure information of each of a plurality of sensing groups included in the sensing group set, a minimum number of responders for the sensing service, a period for resetting the sensing group set, or a reset condition for the sensing group set. Exposure information of a sensing group may include at least one of an index of the sensing group, the number of members of the sensing group, geographic location information covered by the sensing group, geographic area information covered by the sensing group, target sensing service area information of the sensing group, moving target sensing service area information of the sensing group, or member information included in the sensing group. The exposure information may be configured differently depending on the exposure scenario.

[0270] In step S1807, the second device transmits control information or configuration information. The second device can transmit control information or configuration information to the second device. The control information or configuration information can be transmitted using RRC parameters, DCI, or MAC CE.

[0271]

[0272] FIG. 19 illustrates an example of a sensing group configuration procedure according to one embodiment of the present disclosure. FIG. 19 illustrates a method performed by a first device. At least some of the operations in FIG. 19 can be understood as detailed operations of steps S1705 and S1707 of FIG. 17.

[0273] Referring to FIG. 19, in step S1901, the first device obtains information about a sensing group set. The first device can obtain information about the sensing group set based on control information or setting information received from the second device. The information about the sensing group set may include sensing-related information about at least one sensing group among a plurality of preset sensing groups. For example, the information about the sensing group set may include sensing-related information about only at least one sensing group to which the first device belongs, or may include sensing-related information about all of the plurality of sensing groups. The sensing-related information may include at least one of identification information (e.g., an index or ID) of the sensing group, or exposure information of the sensing group. In this case, the exposure information may include at least one of an index, number of members, covered geographic location information, covered geographic area information, target sensing service area information, moving target sensing service area information, or member information, depending on the exposure scenario. According to one embodiment, the control information or configuration information may further include at least one of a minimum number of responders for a sensing service, a period for resetting a sensing group set, or a reset condition for a sensing group set.

[0274] In step S1903, the first device selects a sensing group. The first device can select at least one sensing group based on information about a sensing group set. As described with reference to FIGS. 13 to 16, the first device can select at least one sensing group based on whether a sensing group to which the first device belongs exists. The presence of a sensing group to which the first device belongs can be determined based on information about the sensing group set. If the sensing group to which the first device belongs does not exist, the first device can select at least one sensing group from among a plurality of sensing groups based on exposure information of each of the plurality of sensing groups in the sensing group set. On the other hand, if at least one sensing group to which the first device belongs exists, the first device can select at least one sensing group from among the sensing groups based on exposure information of the at least one sensing group to which it belongs. When selecting a sensing group, the first device can select at least one sensing group by further considering a specified condition. For example, the first device can select at least one sensing group that satisfies a minimum number of respondents.

[0275] In step S1905, the first device performs a sensing measurement process. The first device can perform the sensing measurement process with at least one member within at least one selected sensing group by transmitting information indicating the start of the sensing measurement process. The information indicating the start of the sensing measurement process can be unicast or multicast to at least one member within the at least one selected sensing group. The first device can transmit an index or ID of the at least one selected sensing group together with the information indicating the start of the sensing measurement process. This is to enable other devices that are members of the at least one selected sensing group to recognize that the sensing measurement process of the selected sensing group has started. Thereafter, the first device and at least one other device that is a member of the at least one selected sensing group can perform the sensing measurement configuration setting step, the sensing measurement data generation and reporting step, the sensing measurement configuration termination step, and the sensing group termination step described with reference to FIGS. 7 and / or 8. Here, the first device can terminate the sensing group if the number of respondents reporting the sensing measurement data is less than the minimum number of respondents.

[0276]
