[0087] 5G system architecture applicable to the present disclosure

[0088] 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.

[0089] 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.

[0090] - 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).

[0091] 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.

[0092] 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).

[0093] 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.

[0094] 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.

[0095] 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.

[0096] 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).

[0097] 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.

[0098] 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).

[0099] 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.

[0100] 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.

[0101] Figure 3 illustrates an example of functional separation of NG-RAN and 5GC (5th generation core) applicable to the present disclosure.

[0102] 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). The CPF node includes the AMF and the SMF.

[0103] The UPF node functions as a gateway through which user data is transmitted and received.

[0104] The authentication server function (AUSF) authenticates and manages UEs. The Network Slice Selection Function (NSSF) is a node for network slicing, as described below.

[0105] The network exposure function (NEF) provides a mechanism to securely expose the services and functions of the 5G core.

N81 represents a reference point between an SMF and an NSACF.

[0107] The radio interface protocol is based on the 3GPP radio access network standard. Horizontally, the radio interface protocol consists of the physical layer, data link layer, and network layer. Vertically, it is divided into the user plane for data information transmission and the control plane for control signaling.

[0108] Protocol layers can be divided into L1 (layer-1), L2 (layer-2), and L3 (layer-3) based on the three lower layers of the open systems interconnection (OSI) standard model, which is widely known in communication systems.

[0109] Below, the present disclosure describes each layer of the wireless protocol. Figure 4 illustrates an example of a general architecture of a 5G (5th generation) system applicable to the present disclosure.

[0110] Referring to FIG. 4, the AS (access stratum) layer may include a physical (PHY) layer, a medium access control layer, a radio link control (RLC) layer, a packet data convergence protocol (PDCP) layer, and a radio resource control (RRC) layer, and operations based on each layer may be performed by referring to matters described in standard documents published prior to this document.

[0111]

[0112] Specific embodiments of the present disclosure

[0113] The present disclosure relates to a method and device for dynamically reporting sensing measurement results for a sensing signal based on wireless communication.

[0114]

[0115] 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.

[0116] 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.

[0117] 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.

[0118] - Sensing initiator: An entity that starts the sensing measurement process, which may be a base station, a terminal, or a consumer premise equipment (CPE).

[0119] - 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.

[0120] - 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.

[0121] - 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, UE, or CPE that receives sensing signals transmitted from the sensing transmitter and acquires sensing measurement data in the sensing measurement process.

[0122] 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.

[0123] 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.

[0124] 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.

[0125] 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.

[0126] 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).

[0127] 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.

[0128]

[0129] 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.

[0130] 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.

[0131] 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.

[0132] 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.

[0133] 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.

[0134] 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.

[0135] 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 or repeated once. If necessary, at least one of the sensing group update or the sensing measurement configuration update may be repeated more than once. For example, the sensing measurement configuration setting step (S703) may be performed repeatedly to update the sensing measurement configuration.

[0136] 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.

[0137] 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 a duty cycle or 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.

[0138]

[0139] Setting up sensing groups

[0140] 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.

[0141] 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 a first type of DCI format. 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 who is expected to withdraw or terminate a sensing group in which he or she is participating. When an adjustment status is received from a responder with certain conditions, a sensing initiator determines whether to accept the adjusted conditions.

[0142] 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.

[0143] 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.

[0144] - 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.

[0145] - 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.

[0146] - 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.

[0147] 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.

[0148] 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.

[0149] - 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.

[0150] - If the number of respondents is less than the first threshold, the initiator proceeds to terminate the sensing group setup.

[0151]

[0152] Sensing Measurement Configuration Settings

[0153] 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.

[0154] 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.

[0155] 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 a first type of DCI format. 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 data may be assigned a group of sensing measurement data. 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.

[0156] 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.

[0157] 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.

[0158] 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.

[0159] 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.

[0160] - 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.

[0161] - 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.

[0162] Additional negotiations may be performed between the initiator and responder to set configuration parameters for the sensing measurements.

[0163] - 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.

[0164] - 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.

[0165] 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.

[0166] 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.

[0167]

[0168] Generation and reporting of sensing measurement data

[0169] After the sensing measurement configuration setup is successfully performed, sensing measurement data generation and reporting are performed. As illustrated in Figure 7, some operations during the sensing measurement process, including the sensing measurement data generation and reporting steps, may be repeated, while others may be omitted. Additionally, some operations may be processed jointly.

[0170] 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.

[0171] FIG. 8 illustrates an example of a sensing measurement data generation and reporting procedure based on a sensing measurement configuration setting 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) of forming a sensing group with the first receiver (810-1). Once the sensing group setup is complete, 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) can repeatedly perform the sensing measurement configuration setup 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 can be performed. Generally, the termination can be performed explicitly or implicitly by the initiator or the responder.

[0172]

[0173] End sensing measurement configuration

[0174] 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.

[0175]

[0176] Sensing group termination

[0177] 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.

[0178]

[0179] In 3GPP, Downlink Control Information (DCI) conveys hybrid automatic repeat and request (HARQ) information, physical layer resource allocation, and / or power control commands for uplink and downlink. For example, DCI can convey information for resource scheduling for the PDSCH, resource scheduling information for the PUSCH, and information related to power adjustment of the PUSCH and / or PUCCH for uplink power control. DCI is transmitted via the PDCCH with a 24-bit CRC. Various DCI formats have been defined to meet various requirements and conditions, and NR DCI formats can share the same DCI size for efficient implementation.

[0180] In 3GPP, PUCCH is an uplink physical channel that carries uplink control information (UCI). DCI is carried on the PDCCH, while UCI is carried on the PUCCH. A key difference between DCI and UCI is that UCI can be transmitted on either the PUCCH or the PUSCH, depending on the situation, while DCI can only be transmitted on the PDCCH. DCI is never transmitted on the PDSCH.

[0181] UCI is reported to the network via PUCCH or PUSCH. UCI may include at least one of HARQ ACK / NACK, SR (scheduling request), or CSI. HARQ is a physical layer message that indicates the success or failure of PDSCH decoding at the UE, and SR is a physical layer message that requests an UL grant from the network for PUSCH transmission by the UE. In other words, SR is a message that notifies the network that the UE has data to transmit via uplink. CSI may include several components such as CQI (channel quality information), PMI (precoding matrix indicator), CRI (CSI-RS resource indicator), SSBRI (SS / PBCH (synchronization signal / physical broadcast channel) resource block indicator), LI (layer indicator), RI (rank indicator), and / or L1-RSRP (layer 1 reference signal received power).

[0182] UCI may 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 only as a single UCI. UCI is encoded and transmitted via PUCCH or multiplexed via PUSCH. CSI reporting configuration may be performed aperiodically via PUSCH, periodically via PUCCH, or semi-permanently via PUCCH or DCI-activated PUSCH. To determine PUCCH resources for PUCCH transmission within a slot based on the UCI size, a PUCCH resource indicator field may be used in the DCI format. The PUCCH resource indicator consists of 3 bits in DCI format 1_0 and format 1_1, and bits 0, 1, 2, or 3 can be determined by a higher layer parameter (e.g., numberOfBitsForPUCCH-ResourceIndicatorDCI-1-2).

[0183] For the 3GPP sensing measurement processor, CSI can include new types of channel state information in addition to existing RSs such as CSI-RS, SRS, or PRS (positioning reference signal). Information related to Doppler (e.g., velocity-related information), delay (e.g., position-related information), angle-of-arrival (AoA), and / or angle-of-departure (AoD) can be identified as new types of elements or CSI related to sensing measurements.

[0184] In the present disclosure, information about the sensing measurement process (e.g., SGID, SMID, SMI, etc.) may be newly defined or modified for identification or at any given moment. This information may be included in the UCI or transmitted using separate channels or resources used for identification purposes. Alternatively, this information may be jointly decoded with the sensing measurement data of the UCI. Given that the SGID and SMID are consistent over a certain period of time, the SGID and SMID may be transmitted only when a specific situation changes. For example, if the value of newly defined information is maintained over a certain period of time, the information may not be transmitted. However, if the value of the information is updated based on a specific event, the updated value may be transmitted.

[0185]

[0186] In this disclosure, the sensing measurement process describes a scenario between a base station and a terminal, the signaling related thereto, and channels such as DCI, UCI, PUCCH, or PUSCH. Here, the base station may act as a transmitter or initiator, and the terminal may act as a receiver or responder. However, the present disclosure is not limited thereto. For example, the method proposed in this disclosure may be equally applied to at least one of a scenario between a plurality of base stations and one base station, a scenario between a base station and multiple base stations, a scenario between a base station and multiple terminals, a scenario between multiple terminals and one terminal, or a scenario between a terminal and one terminal. That is, the signaling, channels, and / or interfaces proposed in this disclosure may be appropriately replaced or modified to support the same or similar purposes and functions.

[0187] A scenario involving multiple base stations acting as transmitters or initiators and terminals acting as receivers or responders will be described in the final section of this disclosure. The methods and corresponding sensing and measurement processes associated with the base stations and terminals proposed in this disclosure can be reused, modified, or replaced with new methods and sensing and measurement processes applicable to multiple base stations and terminals.

[0188]

[0189] FIG. 9 illustrates an example of a sensing measurement data generation and reporting procedure that dynamically changes based on sensing measurement configuration settings applicable to the present disclosure. Here, a transmitter may be a transmitter for a sensing service, for example, a base station, and receivers (910-1, 910-2, 910-3) may be receivers for the sensing service, for example, terminals.

[0190] Referring to FIG. 9, in step S901, the transmitter (920) may perform a sensing group setting step to form a sensing group with at least one of the first receiver (910-1), the second receiver (910-2), and the third receiver (910-3). Here, the transmitter (920) may form a sensing group with the first receiver (910-1) through the sensing group setting step.

[0191] Thereafter, the transmitter (920) and the first receiver (910-1) can repeatedly perform the sensing measurement configuration setting steps (S903, S907, S911) and the sensing measurement data generation and reporting steps (S905, S909, S913). In the sensing measurement configuration setting steps (S903, S907, S911), the transmitter (920) can transmit a sensing measurement configuration setting notification signal to the first receiver (910-1). The sensing measurement configuration setting notification signal can include an SGID and an SMID. The SGID can be maintained at the same value until the corresponding sensing group is terminated, and the SMID can be maintained at the same value until the next sensing measurement configuration setting is performed. In addition, the sensing measurement configuration setting notification signal can further include sensing measurement configuration setting information necessary for sensing measurement, as described above. For example, the sensing measurement configuration setting notification signal may include information about at least one of the period, frequency, or interval for generating and / or reporting sensing measurement data, and the content of the report.

[0192] In the sensing measurement data generation and reporting steps (S905, S909, S913), the transmitter (920) transmits at least one sensing signal based on the sensing measurement configuration setting information, and the first receiver (910-1) generates sensing measurement data for a sensing signal reflected by a target based on the sensing measurement configuration setting information, and can report the generated sensing measurement data.

[0193] The amount of sensing measurement data reported by the first receiver (910-1) can be dynamically changed during the repeated execution of the sensing measurement configuration setting steps (S903, S907, S911) and the sensing measurement data generation and reporting steps (S905, S909, S913) as described above. In other words, the amount of sensing measurement data to be reported can be dynamically changed according to the sensing measurement configuration setting notification and / or the sensing measurement instant.

[0194] For example, in a situation where SGID and SMID are 1 and 1, respectively, the first receiver (910-1) can generate and report sensing measurement data 1, 2, and 3 at a first sensing measurement time point (S921), and generate and report sensing measurement data 2 and 3 at a second sensing measurement time point (S923), based on sensing measurement configuration setting information set based on a sensing measurement configuration setting notification signal of SMID=1. That is, sensing measurement data 2 and 3 can be generated and reported at every sensing measurement moment, and sensing measurement data 1 can be generated and reported every time two sensing measurements are performed.

[0195] As another example, in a situation where SGID and SMID are 1 and 2, respectively, the first receiver (910-1) generates and reports sensing measurement data 1, 2, and 3 at the Nth sensing measurement time point according to the sensing measurement configuration setting set based on the sensing measurement configuration setting notification signal of SMID=2 (S931).

[0196] As another example, in a situation where SGID and SMID are 1 and 3, respectively, the first receiver (910-1) generates sensing measurement data 1 and 2 at the Mth sensing measurement time point, and generates and reports sensing measurement data 1 and 2 at the (M+1)th sensing measurement time point according to the sensing measurement configuration setting set based on the sensing measurement configuration setting notification signal of SMID=3 (S941). Here, the reported sensing measurement data 1 and 2 may be an average value of the sensing measurement data 1 and 2 generated at the Mth sensing measurement time point and the sensing measurement data 1 and 2 generated at the (M+1)th sensing measurement time point. That is, the sensing measurement data 1 and 2 are generated at every sensing measurement moment, but the reporting may be performed every time two sensing measurements are performed.

[0197]

[0198] The present disclosure describes a method and device for dynamically reporting sensing measurement results for a sensing signal based on sensing measurement configuration information.

[0199] Once the sensing measurement configuration is established by the transmitter, the transmitter can anticipate the UCI size for all sensing measurement reports from the receiver. In this case, the UCI size for the sensing measurement data to be reported can be indicated via DCI. Assuming dynamic and flexible signaling based on various sensing measurement services with various types of measurement objects, two options are proposed to support UCIs of various sizes. In an embodiment, either Option 1 or Option 2 may be configured or indicated.

[0200] Option 1

[0201] The transmitter can accurately estimate the UCI size based on the sensing measurement configuration information established by the transmitter. In this case, UCIs of various sizes transmitting sensing measurement data can be successfully received. In terms of implementation complexity, the UCI size can vary depending on the receiver's capabilities. Considering the variable size, implementation complexity will not be burdened by the receiver's capabilities.

[0202] Option 2

[0203] Depending on the design method, considering the supported dynamic signaling, the variation of the UCI size may be limited to implement efficient sensing and decoding. For example, a single-size UCI may be defined using padding bits, if necessary. Alternatively, a limited number of UCI sizes may be defined using padding bits, if necessary. These padding bits may be fixed values ​​such as 0 or 1, or may be a specific pattern for future use. To limit the variation of the UCI size, Method 1 or Method 2 may be configured or indicated as follows. Only one of Method 1 or Method 2 may be supported at a given time.

[0204] Method 1: This method limits changes in UCI size by using information indicating the presence or absence of certain information in the UCI. This information can be a bitmap. For example, a bitmap indicating whether the UCI should include CQI, RI, PMI, Doppler, or delay is used.

[0205] Method 2: This method limits the UCI size to a specific size using information indicating the UCI size. The information indicating the UCI size can indicate the state of the UCI size. For example, the information indicating the UCI size can indicate one of three states: N-bit UCI, M-bit UCI, or K-bit UCI.

[0206] Information for Method 1 and / or Method 2 may be determined by the transmitter and included in the DCI as follows.

[0207] Option 2-1. Reuse of existing DCI

[0208] - A 3-bit PUCCH resource indicator field can be assigned to DCI formats 0_0 and 0_1, and 0, 1, 2, or 3 bits can be assigned to DCI format 0_2 using upper layer configuration.

[0209] - If 3 bits are sufficient or there is a reservation left in the bits, the existing DCI can be reused.

[0210] - If 3 bits are not sufficient, one state or one bit is used to indicate that additional combinations are possible. For example, a control information state or control information field is used. If a control information state or control information field is indicated, one or more states or bits may be newly interpreted for Method 1 or Method 2.

[0211] - If 3 bits are not enough, at least one more bit can be added. For example, a PUCCH resource indicator_relX field can be added. To include more bits in an existing DCI type, higher layer signaling can be configured to indicate the presence of new bits in the DCI and the DCI size.

[0212] Option 2-2. A new type of DCI

[0213] - A new type of DCI can be defined for the sensing measurement process.

[0214] - The UCI size including the PUCCH resource indicator can be newly defined depending on the use case of the sensing measurement process.

[0215] - The PUCCH resource indicator field can support UCIs of various sizes.

[0216]

[0217] The 3GPP system supports mechanisms that enable the 3GPP network to retrieve wireless sensing capabilities from UEs and RAN entities, and to exchange wireless sensing capabilities between UEs and RAN entities. For example, a UE and / or RAN entity device may enter a personal location area (home, work, or registered location) where the 3GPP sensing measurement process is no longer supported. In another example, a device may contribute to the sensing measurement service of another device only for a certain period of time. That is, depending on various sensing use cases, a situation may arise where only the receiver is aware of or can sense updated sensing capabilities and / or sensing conditions of the sensing measurement process. In this case, the transmitter may become aware of this situation when the expected sensing measurement data is not delivered to the transmitter, or when unexpected sensing measurement data is delivered to the transmitter. This means that the UCI size indicated by the transmitter via DCI may not match the UCI size responded by the receiver. If the UCI size does not match, the transmitter will not be able to decode the UCI. Therefore, if the receiver indicates that the amount of resources required for UCI for a certain period of time is small, the transmitter can indicate a new size of uplink resources for UCI for the sensing measurement data to be reported.

[0218] To address the aforementioned UCI size mismatch, the receiver can transmit indication information indicating whether the UCI size indicated by the DCI and the UCI size in the response are the same. The transmitter can first detect the indication information to estimate the UCI size. The indication information can be a single-bit information. For example, it can be a single-bit information indicating a single-size UCI or a fixed-size UCI in the response. Alternatively, the indication can be information consisting of one or more bits indicating various UCI sizes in the response. For example, information consisting of one or more bits can be used to have a limited number of UCI sizes using Method 1 or Method 2, as shown below.

[0219] UCI size variations can be limited to allow for efficient detection and decoding, using dynamic signaling to prevent the transmitter from predicting the UCI size for any reason. For example, a single-size UCI can be defined using padding bits, if necessary. Alternatively, a limited number of UCI sizes can be defined using padding bits, if necessary.

[0220] Method 1: Information indicating the information to be included in the UCI is used. This information may be a bitmap. For example, this information may consist of an 8-bit bitmap indicating the presence of CQI, RI, PMI, …, Doppler, or delay.

[0221] -Method 2: When the UCI size is limited to a specific number, information is used to indicate the UCI size. This information can indicate each state, and each state indicates an N-bit UCI, an M-bit UCI, or a K-bit UCI.

[0222] Information from methods 1 and / or 2 may be determined by the receiver to be first decoded to obtain the UCI size.

[0223]

[0224] Figure 10 illustrates an example of a sensing measurement data reporting procedure according to one embodiment of the present disclosure. Figure 10 illustrates a method performed by a terminal. The terminal can act as a receiver for a sensing service.

[0225] Referring to FIG. 10, in step S1001, the terminal receives a capability information request. The terminal may receive a message requesting transmission of the terminal's capability information from the base station.

[0226] In step S1003, the terminal transmits its capability information. 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 terminal supports the sensing service, information on the terminal's computational capabilities, or the types of raw data that the terminal can process. According to one embodiment, a sensing group of terminals may be formed based on the terminal's capability information.

[0227] In step S1005, the terminal receives control information related to measurement. In other words, the terminal receives control information related to measurement including information necessary for measuring a signal. According to one embodiment, the control information related to measurement may be received using DCI, and the control information related to measurement may include information for limiting the size of UCI. For example, the control information related to measurement may include information for limiting the size of sensing measurement data to be reported. According to one embodiment, the control information related to measurement may include information necessary for measuring a sensing signal of a sensing transmitter and / or a sensing receiver within a sensing group. For example, the control information related to measurement may include at least one of a sensing group setting ID, a sensing measurement configuration setting ID, a type of sensing measurement data, a time point or frequency of generating sensing measurement data, a time point or frequency of reporting sensing measurement data, a type of sensing measurement data to be reported, a size of sensing measurement data to be reported, a threshold value, or a time interval.

[0228] In step S1007, the terminal receives a signal for measurement. In other words, the terminal receives a signal based on control information related to measurement. For example, the terminal may receive a sensing signal that is transmitted from a transmitter within a sensing group and then reflected, refracted, or diffracted by a target based on sensing measurement configuration information. At this time, the terminal generates a measurement result including measurement data for the received signal. For example, the terminal may generate sensing measurement data for the sensing signal based on sensing measurement configuration information.

[0229] In step S1009, the terminal transmits a measurement result report. The terminal reports sensing measurement data based on control information related to the measurement. The sensing measurement data can be reported using UCI. The terminal can obtain UCI size limit information from the control information related to the measurement, and based on the obtained UCI size limit information, report sensing measurement data of a limited size as a measurement result for the sensing signal. For example, the terminal can calculate a delta value corresponding to the difference between the sensing measurement data for a previously received sensing signal and the sensing measurement data for a currently received sensing signal, and report the calculated delta value as a measurement result.

[0230]

[0231] FIG. 11 illustrates an example of a sensing measurement data reception procedure according to one embodiment of the present disclosure. FIG. 11 illustrates a method performed by a base station. The base station may operate as a transmitter for a sensing service.

[0232] Referring to FIG. 11, in step S1101, the base station transmits a request for capability information. The base station may transmit a message requesting transmission of capability information to the terminal.

[0233] In step S1103, the base station receives capability information. That is, the base station receives capability information of the terminal. 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 terminal supports the sensing service, information on the terminal's computational capability, or the type of raw data that the terminal can process. According to one embodiment, a sensing group may be formed based on the terminal's capability information.

[0234] In step S1105, the base station transmits control information related to measurement. In other words, the base station transmits control information related to measurement including information necessary for measuring a signal. According to one embodiment, the control information related to measurement may be transmitted using DCI, and the control information related to measurement may include information for limiting the size of the UCI of the terminal. For example, the control information related to measurement may include information for limiting the size of sensing measurement data to be reported from the terminal. According to one embodiment, the control information related to measurement may include information necessary for measuring a sensing signal of a sensing transmitter and / or a sensing receiver within a sensing group. For example, the control information related to measurement may include at least one of a sensing group configuration ID, a sensing measurement configuration configuration ID, a type of sensing measurement data, a time point or frequency of generating sensing measurement data, a time point or frequency of reporting sensing measurement data, a type of sensing measurement data to be reported, a size of sensing measurement data to be reported, a threshold value, or a time interval.

[0235] In step S1107, the base station transmits a signal for measurement. In other words, the base station transmits a signal based on control information related to the measurement. For example, the base station may transmit a sensing signal toward the target based on sensing measurement configuration information.

[0236] In step S1109, the base station receives a measurement result report. The base station receives a report on sensing measurement data generated based on the sensing signal. The report on the sensing measurement data may be received via UCI. At this time, the size of the reported sensing measurement data may match the UCI size limited by the base station via DCI. The reported sensing measurement data may include a difference value, i.e., a delta value, between the sensing measurement data for the last transmitted sensing signal and the sensing measurement data for the previously transmitted sensing signal.

[0237]

[0238] The present disclosure proposes an efficient method for conserving UCI resources while reporting differences in channel measurement data measured from consecutive sensing signals. In the methods described below, the transmitter does not predict the UCI size within the response. In this case, the aforementioned methods or options can be applied jointly.

[0239] Case 1: After the transmitter successfully receives and / or detects the sensing measurement result for the first sensing signal, the receiver reports a delta value, which is the difference between the current sensing measurement data and the first sensing measurement data.

[0240] FIG. 12 illustrates an example of a procedure for reporting a difference in sensing measurement data according to one embodiment of the present disclosure.

[0241] Referring to FIG. 12, in step S1201, the transmitter (1220) and the receiver (1210) form a sensing group by performing a sensing group setup procedure. The transmitter (1220) that forms the sensing group may be a base station, and the receiver (1210) may be a terminal. However, the present disclosure is not limited thereto.

[0242] In step S1203, the transmitter (1220) and the receiver (1210) perform a sensing measurement configuration setting procedure to set information required for sensing measurement. For example, the transmitter (1220) may transmit a sensing measurement configuration setting notification signal including sensing measurement configuration setting information to the receiver (1210). The sensing measurement configuration setting notification signal may include an SGID and an SMID.

[0243] In step S1205, the transmitter (1220) and the receiver (1210) perform a sensing measurement data generation and reporting procedure. The sensing measurement data generation and reporting procedure may be composed of a sensing signal transmission step (S1211, S1215, S1219) and a sensing measurement data reporting step (S1213, S1217, S1221).

[0244] Specifically, in step S1211, the transmitter (1220) transmits a first sensing signal. For example, the transmitter (1220) may transmit a first sensing signal having SGID=1, SMID=1, and SMI=1. The SMI (sensing measurement index) may be an index assigned to the sensing signal. The sensing signals transmitted at each designated time from the transmitter (1220) until the sensing measurement configuration is terminated may have different indices. At this time, the receiver (1210) performs a measurement on the sensing signal having SMI=1 and generates first sensing measurement data based on the measurement result.

[0245] In step S1213, the receiver (1210) reports the first sensing measurement data with SMI=1 as a sensing measurement result for the first sensing signal. At this time, the transmitter (1220) may attempt to receive and / or detect the sensing measurement result for the first sensing signal. FIG. 12 assumes that the transmitter (1220) successfully receives and / or detects the sensing measurement result for the first sensing signal with SMI=1.

[0246] In step S1215, the transmitter (1220) transmits a second sensing signal. For example, the transmitter (1220) transmits a second sensing signal having SGID=1, SMID=1, and SMI=2. At this time, the transmitter can transmit first information indicating whether the transmitter has successfully received a sensing measurement result for the first sensing signal having SMI=1 using the second sensing signal. Here, the first information indicates that the transmitter has successfully received a sensing measurement result for the first sensing signal having SMI=1. The receiver (1210) performs a measurement for the second sensing signal having SMI=2 and generates second sensing measurement data based on the measurement result.

[0247] In step S1217, the receiver (1210) may report a delta value, which is a difference between the first sensing measurement data and the second sensing measurement data, to the transmitter (1220) as a sensing measurement result for the second sensing signal. That is, since the transmitter (1220) successfully receives the first sensing measurement data, the receiver (1210) may not transmit the entire second sensing measurement data, but may report a difference value between the first sensing measurement data and the second sensing measurement data. At this time, the transmitter (1220) may attempt to receive and / or detect a sensing measurement result for the second sensing signal. When the delta value, which is a difference between the first sensing measurement data and the second sensing measurement data, is received as a sensing measurement result for the second sensing signal, the transmitter (1220) may estimate the second sensing measurement data based on the received delta value and the first sensing measurement data.

[0248] In step S1219, the transmitter (1220) transmits a third sensing signal. For example, the transmitter (1220) transmits a third sensing signal having SGID=1, SMID=1, and SMI=3. The receiver (1210) performs measurement on the third sensing signal having SMI=3 and generates third sensing measurement data based on the measurement result.

[0249] In step S1221, the receiver (1210) may report a delta value, which is a difference between the first sensing measurement data and the third sensing measurement data, to the transmitter (1220) as a sensing measurement result for the third signal. That is, since the transmitter (1220) successfully received the first sensing measurement data, the receiver (1210) may not transmit the entire third sensing measurement data, but may report a difference value between the first sensing measurement data and the third sensing measurement data. At this time, the transmitter (1220) may attempt to receive and / or detect the sensing measurement result for the third sensing signal.

[0250] In the embodiment described with reference to FIG. 12, the first information may be transmitted along with the corresponding SMI. The first information may indicate which components of the sensing measurement data were correctly or incorrectly received. If some components are indicated as not being successfully received or detected, some data reported to the transmitter may be delta values, and other data may be sensing measurement data.

[0251] According to one embodiment, the delta value may be generated based on sensing measurement data for a sensing signal having a specific SMI. For example, when reporting a sensing measurement result for a sensing signal having an SMI of 2, the reported delta value may be the difference between the sensing measurement data for the sensing signal having an SMI of 1 and the sensing measurement data for the sensing signal having an SMI of 2. When reporting a sensing measurement result for a sensing signal having an SMI of 3, the reported delta value may be the difference between the sensing measurement data for the sensing signal having an SMI of 1 and the sensing measurement data for the sensing signal having an SMI of 3.

[0252] To reduce signaling complexity, the transmitter can choose to transmit either all sensing measurement data or a delta value for all sensing measurement data. This approach may be reasonable, considering that most components of the sensing measurement data are likely to change due to large-scale channel effects.

[0253]

[0254] FIG. 13 illustrates another example of a procedure for reporting differences in sensing measurement data according to one embodiment of the present disclosure. Here, steps S1301 and S1303 may be performed in the same manner as steps S1201 and S1203 of FIG. 12 . Therefore, a description thereof will be omitted.

[0255] Referring to FIG. 13, in step S1305, the transmitter (1320) and the receiver (1310) perform a sensing measurement data generation and reporting procedure. The sensing measurement data generation and reporting procedure may be composed of a sensing signal transmission step (S1311, S1315, S1319) and a sensing measurement data reporting step (S1313, S1317, S1321). Here, the transmitter (1320) may be a base station, and the receiver (1310) may be a terminal. However, the present disclosure is not limited thereto.

[0256] Specifically, in step S1311, the transmitter (1320) transmits a first sensing signal. For example, the transmitter (1320) may transmit a first sensing signal having SGID=1, SMID=1, and SMI=1. At this time, the receiver (1310) performs measurement on the first sensing signal having SMI=1 and generates first sensing measurement data based on the measurement result.

[0257] In step S1313, the receiver (1310) reports the first sensing measurement data with SMI=1 as a sensing measurement result for the first sensing signal. At this time, the transmitter (1320) may attempt to receive and / or detect the sensing measurement result for the first sensing signal. FIG. 13 assumes a case where the sensing measurement result for the first sensing signal with SMI=1 is not successfully received and / or detected by the transmitter (1320).

[0258] In step S1315, the transmitter (1320) transmits a second sensing signal. For example, the transmitter (1320) transmits a second sensing signal having SGID=1, SMID=1, and SMI=2. At this time, the transmitter can transmit first information indicating whether a sensing measurement result for a first sensing signal having SMI=1 was successfully received using the second sensing signal. Here, the first information indicates that a sensing measurement result for the first sensing signal having SMI=1 was not successfully received. The receiver (1310) performs a measurement for the second sensing signal having SMI=2 and generates second sensing measurement data based on the measurement result.

[0259] At step S1317, the receiver (1310) may report the second sensing measurement data to the transmitter (1320). That is, since the transmitter (1320) did not successfully receive or detect the sensing measurement result for the first sensing signal, the receiver (1310) may report the entire second sensing measurement data as the sensing measurement result for the second sensing signal. At this time, the transmitter (1320) may attempt to receive and / or detect the sensing measurement result for the second sensing signal. FIG. 13 assumes a case where the sensing measurement result for the second sensing signal with SMI=2 is successfully received and / or detected.

[0260] In step S1319, the transmitter (1320) transmits a third sensing signal. For example, the transmitter (1320) transmits a third sensing signal having SGID=1, SMID=1, and SMI=3. At this time, the transmitter can transmit first information indicating whether a sensing measurement result for a second sensing signal having SMI=2 was successfully received using the third sensing signal. Here, the first information indicates that the sensing measurement result for the second sensing signal having SMI=2 was successfully received. The receiver (1310) performs a measurement for the third sensing signal having SMI=3 and generates third sensing measurement data based on the measurement result.

[0261] In step S1321, the receiver (1310) may report a delta value, which is a difference between the second sensing measurement data and the third sensing measurement data, to the transmitter (1320) as a sensing measurement result for the third sensing signal. That is, since the transmitter (1320) successfully received the second sensing measurement data, the receiver (1310) may report a difference value between the second sensing measurement data and the third sensing measurement data without transmitting the entire third sensing measurement data.

[0262] As described with reference to FIG. 13, if the sensing measurement result for the sensing signal with SMI=n is not successfully received and / or detected by the transmitter (e.g., base station), the next sensing signal with SMI=n+1 may convey to the receiver (e.g., terminal) information indicating what problem occurred at the transmitter with respect to the previously reported sensing measurement result. In response, the receiver reports the sensing measurement result for the sensing signal with SMI=n+1 and checks again whether information indicating whether the report was correctly received is conveyed in the next sensing signal with SMI=n+2. If the sensing measurement result for the sensing signal with SMI=n+1 is successfully received, the transmitter may convey information indicating this using the next sensing signal with SMI=n+2. In this case, when reporting the sensing measurement result for the sensing signal with SMI=n+2, a delta value, which is a difference value of sensing measurement data between the sensing signal with SMI=n+1 and the sensing signal with SMI=n+2, may be reported.

[0263] In the description with reference to FIG. 13, detection of a sensing measurement result may be performed based on a time boundary, a time interval, or a timer. For example, after transmitting a sensing signal, the transmitter may detect whether a sensing measurement result for the sensing signal is detected during a predefined, configured, or indicated time boundary, time interval, or timer operation.

[0264] In the description with reference to Fig. 13, when the sensing measurement result is not detected, the next sensing signal is used to transmit information indicating what problem occurred in the transmitter with respect to the sensing measurement result reported by the receiver. However, the next sensing signal may be transmitted without the information. At least, both the transmitter and the receiver know the value of the time interval, and the transmitter can consider there to be no error through the regular sensing measurement process during the time interval. The value of the time boundary can be configured as a single value by the upper layer parameter, or can be configured by the upper layer parameter to activate the corresponding capability. The value of the time boundary can be configured as one or more values ​​by the upper layer parameter. To indicate the value of the time boundary, the DCI or MAC CE can be used to dynamically indicate one of the predefined values ​​configured by the upper layer parameter or as each fixed value with each corresponding state.

[0265] According to one embodiment, a timer may be defined as follows. The timer is started upon transmission of the first sensing signal. The timer starts from an initial value (e.g., 0) and may include a predefined offset value. Here, the predefined offset value may be separately included as an additional time offset in the sensing measurement configuration information. The predefined offset value may be configured by an RRC common or RRC terminal-specific parameter.

[0266] When a sensing measurement result is reported, a timer is stopped or reset to its initial value in response. Upon expiration of the timer, the transmitter may reset the timer to its initial value for the next corresponding operation. Alternatively, upon expiration of the timer, the transmitter may terminate the sensing configuration if a specific condition is satisfied. For example, the transmitter may terminate the sensing measurement configuration if no sensing measurement result is received within a predefined, configured, or indicated second time interval or time period.

[0267]

[0268] Case 2: After the transmitter successfully receives and / or detects the previous sensing measurement result, the receiver can transmit a delta value, which is the difference between the previous sensing measurement data and the current sensing measurement data.

[0269] FIG. 14 illustrates another example of a procedure for reporting differences in sensing measurement data according to one embodiment of the present disclosure. Here, steps S1401 and S1403 may be performed in the same manner as steps S1201 and S1203 of FIG. 12 . Therefore, a description thereof will be omitted.

[0270] Referring to FIG. 14, in step S1405, the transmitter (1420) and the receiver (1410) perform a sensing measurement data generation and reporting procedure. The sensing measurement data generation and reporting procedure may be composed of a sensing signal transmission step (S1411, S1415, S1419) and a sensing measurement data reporting step (S1413, S1417, S1421). Here, the transmitter (1420) may be a base station, and the receiver (1410) may be a terminal. However, the present disclosure is not limited thereto.

[0271] Specifically, in step S1411, the transmitter (1420) transmits a first sensing signal. For example, the transmitter (1420) may transmit a first sensing signal having SGID=1, SMID=1, and SMI=1. At this time, the receiver (1410) performs measurement on the first sensing signal having SMI=1 and generates first sensing measurement data based on the measurement result.

[0272] In step S1413, the receiver (1410) reports the first sensing measurement data with SMI=1 as a measurement result for the first sensing signal. At this time, the transmitter (1420) may attempt to receive and / or detect the measurement result for the first sensing signal. FIG. 14 assumes that the transmitter (1420) successfully receives and / or detects the measurement result for the first sensing signal with SMI=1.

[0273] In step S1415, the transmitter (1420) transmits a second sensing signal. For example, the transmitter (1420) transmits a second sensing signal having SGID=1, SMID=1, and SMI=2. At this time, the transmitter can transmit first information indicating whether the transmitter has successfully received a measurement result for the first sensing signal having SMI=1 using the second sensing signal. Here, the first information indicates that the transmitter has successfully received a measurement result for the first sensing signal having SMI=1. The receiver (1410) performs a measurement for the second sensing signal having SMI=2 and generates second sensing measurement data based on the measurement result.

[0274] In step S1417, the receiver (1410) may report a delta value, which is a difference between the first sensing measurement data and the second sensing measurement data, to the transmitter (1420) as a measurement result for the second sensing signal. That is, since the transmitter (1420) successfully received the measurement result for the first sensing signal that was previously transmitted, the receiver (1410) may report the difference value between the first sensing measurement data and the second sensing measurement data without transmitting the entire second sensing measurement data. At this time, the transmitter (1420) may attempt to receive and / or detect the measurement result for the second sensing signal. FIG. 14 assumes a case where the transmitter (1420) successfully receives and / or detects the measurement result for the second sensing signal with SMI=2. When a delta value, which is a difference between the first sensing measurement data and the second sensing measurement data, is received as a sensing measurement result for the second sensing signal, the transmitter (1420) can estimate the second sensing measurement data based on the received delta value and the first sensing measurement data.

[0275] In step S1419, the transmitter (1420) transmits a third sensing signal. For example, the transmitter (1220) transmits a third sensing signal having SGID=1, SMID=1, and SMI=3. At this time, the transmitter can transmit first information indicating whether the transmitter successfully received the measurement result for the second sensing signal having SMI=2 using the third sensing signal. Here, the first information indicates that the measurement result for the second sensing signal having SMI=2 was successfully received by the transmitter. The receiver (1410) performs measurement for the third sensing signal having SMI=3 and generates third sensing measurement data based on the measurement result.

[0276] In step S1421, the receiver (1410) may perform measurement on the third sensing signal with SMI=3, and report a delta value, which is a difference between the second sensing measurement data and the third sensing measurement data, to the transmitter (1420) as a measurement result for the third sensing signal. That is, since the transmitter (1420) successfully received the measurement result for the previously transmitted second sensing signal, the receiver (1410) may report a difference value between the second sensing measurement data and the third sensing measurement data without transmitting the entire third sensing measurement data.

[0277] As described with reference to FIG. 14, if the measurement result for the previous sensing signal is successfully received or detected, the transmitter may transmit first information indicating that the measurement result for the previous sensing signal was correctly received using the next sensing signal.

[0278] The first information may indicate which components of the sensing measurement data were received correctly or incorrectly. If one or more of the components are indicated as being detected correctly or incorrectly, some of the data reported to the transmitter may be delta values ​​and other portions may be sensing measurement data. To clarify which sensing signal and / or sensing measurement data the first information relates to, a corresponding SMI may be transmitted along with the first information. Here, the corresponding SMI refers to the SMI of the most recently successfully received and / or detected sensing measurement data. If a delta value is received, the transmitter can determine the sensing measurement data for the current SMI based on the sensing measurement data having the corresponding SMI and the delta value.

[0279] According to one embodiment, the delta value may be generated based on sensing measurement data having a corresponding SMI. For example, if the most recently successfully received and / or detected sensing measurement data has an SMI of 1 and a sensing measurement result for a second sensing signal having a current SMI=2 is to be reported, the delta value may be the difference between the sensing measurement data for the first sensing signal having an SMI=1 and the sensing measurement data for the second sensing signal having an SMI=2. As another example, if the most recently successfully received and / or detected sensing measurement data has an SMI of 2 and a sensing measurement result for a third sensing signal having a current SMI=3 is to be reported, the delta value may be the difference between the sensing measurement data for the second sensing signal having an SMI=2 and the sensing measurement data for the third sensing signal having an SMI=3.

[0280] To reduce signaling complexity, the transmitter can choose to transmit either all sensing measurement data or a delta value for all sensing measurement data. This approach may be reasonable, considering that most components of the sensing measurement data are likely to change due to large-scale channel effects.

[0281]

[0282] FIG. 15 illustrates another example of a procedure for reporting differences in sensing measurement data according to one embodiment of the present disclosure. Here, steps S1501 and S1503 may be performed in the same manner as steps S1201 and S1203 of FIG. 12 . Therefore, a description thereof will be omitted.

[0283] Referring to FIG. 15, in step S1505, the transmitter (1520) and the receiver (1510) perform a sensing measurement data generation and reporting procedure. The sensing measurement data generation and reporting procedure may be composed of a sensing signal transmission step (S1511, S1515, S1519) and a sensing measurement data reporting step (S1513, S1517, S1521). Here, the transmitter (1520) may be a base station, and the receiver (1510) may be a terminal. However, the present disclosure is not limited thereto.

[0284] Specifically, in step S1511, the transmitter (1520) transmits a first sensing signal. For example, the transmitter (1520) may transmit a first sensing signal having SGID=1, SMID=1, and SMI=1. At this time, the receiver (1510) performs a measurement on the sensing signal having SMI=1 and generates first sensing measurement data based on the measurement result.

[0285] In step S1513, the receiver (1510) reports the first sensing measurement data with SMI=1 as a sensing measurement result for the first sensing signal. At this time, the transmitter (1520) may attempt to receive and / or detect the sensing measurement result for the first sensing signal and determine whether the first sensing measurement data is successfully received and / or detected. FIG. 15 assumes a case where the sensing measurement result for the first sensing signal with SMI=1 is successfully received and / or detected by the transmitter (1520).

[0286] In step S1515, the transmitter (1520) transmits a second sensing signal. For example, the transmitter (1420) transmits a second sensing signal having SGID=1, SMID=1, and SMI=2. At this time, the transmitter can transmit first information indicating whether the transmitter has successfully received a sensing measurement result for the first sensing signal having SMI=1 using the second sensing signal. Here, the first information indicates that the transmitter has successfully received a sensing measurement result for the first sensing signal having SMI=1. The receiver (1510) performs a measurement for the second sensing signal having SMI=2 and generates second sensing measurement data based on the measurement result.

[0287] In step S1517, the receiver (1510) may report a delta value, which is a difference between the first sensing measurement data and the second sensing measurement data, to the transmitter (1520). That is, since the previously transmitted first sensing measurement data was successfully received by the transmitter (1520), the receiver (1510) may not transmit the entire second sensing measurement data, but may report a difference value between the first sensing measurement data and the second sensing measurement data. At this time, the transmitter (1520) may attempt to receive and / or detect a sensing measurement result for the second sensing signal. FIG. 15 assumes a case where the sensing measurement result for the second sensing signal with SMI=2 is not successfully received and / or detected by the transmitter (1520).

[0288] In step S1519, the transmitter (1520) transmits a third sensing signal. For example, the transmitter (1220) transmits a third sensing signal having SGID=1, SMID=1, and SMI=3. At this time, the transmitter can transmit first information indicating whether the transmitter successfully received a sensing measurement result for a second sensing signal having SMI=2 using the third sensing signal. Here, the first information indicates that the sensing measurement result for the second sensing signal having SMI=2 was not successfully received by the transmitter. The receiver (1510) performs a measurement for the third sensing signal having SMI=2 and generates third sensing measurement data based on the measurement result.

[0289] In step S1521, the receiver (1510) may perform measurement on the third sensing signal with SMI=3 and report a delta value, which is a difference between the first sensing measurement data and the third sensing measurement data, to the transmitter (1520). That is, the receiver (1510) may report a difference value between the first sensing measurement data and the third sensing measurement data, which are sensing measurement data most recently successfully received and / or detected by the transmitter (1520). At this time, the transmitter (1520) may estimate the third sensing measurement data based on the received delta value and the first sensing measurement data.

[0290] As described with reference to FIG. 15, if a sensing measurement result for a sensing signal with SMI=n+1 is not successfully received and / or detected by a transmitter (e.g., a base station), the next sensing signal with SMI=n+2 may convey to the receiver first information indicating what problem occurred in the transmitter with respect to the previously reported sensing measurement result. In response, the receiver (e.g., a terminal) reports sensing measurement delta data, which is a difference value between the sensing measurement data for the sensing signal with SMI=n+2 and the sensing measurement data for the most recently successfully received and / or detected sensing signal.

[0291] Referring to FIG. 15, detection of sensing measurement data can be performed based on a time boundary, a time interval, or a timer. For example, after transmitting a sensing signal, the transmitter can detect whether a sensing measurement result for the sensing signal is detected during a predefined, configured, or indicated time boundary, time interval, or timer operation.

[0292] In the description with reference to Fig. 15, when the sensing measurement result is not detected, the transmitter transmits information indicating what problem occurred in the transmitter for the sensing measurement data reported by the receiver using the next sensing signal. However, the next sensing signal may be transmitted without the information. At least, both the transmitter and the receiver know the value of the time interval, and the transmitter can consider that there is no error through the regular sensing measurement process during the time interval. The value of the time boundary can be configured as a single value by the upper layer parameter, or can be configured by the upper layer parameter to activate the corresponding capability. The value of the time boundary can be configured as one or more values ​​by the upper layer parameter. To indicate the value of the time boundary, the DCI or MAC CE can be used to dynamically indicate one of the predefined values ​​configured by the upper layer parameter or as each fixed value with each corresponding state. In response, the receiver reports sensing measurement delta data between the current sensing measurement report (e.g., the measurement report for a sensing signal with SMI=3) and the sensing measurement report based on the most recently correctly detected sensing signal with SMI (e.g., the measurement report for a sensing signal with SMI=1).

[0293] According to one embodiment, a timer may be defined as follows. The timer is started upon transmission of the first sensing signal. The timer starts from an initial value (e.g., 0) and may include a predefined offset value. Here, the predefined offset value may be separately included as an additional time offset in the sensing measurement configuration information. The predefined offset value may be configured by an RRC common or RRC terminal-specific parameter.

[0294] When reporting a sensing measurement result, a timer is stopped or reset to its initial value in response. Upon expiration of the timer, the transmitter may reset the timer to its initial value for the next corresponding operation. Alternatively, upon expiration of the timer, the transmitter may terminate the sensing configuration if a specific condition is met. For example, the transmitter may terminate the sensing measurement configuration if no sensing measurement result is received within a predefined, configured, or indicated second time interval.

[0295]

[0296] Case 3: When the changes between sensing measurement data for consecutive sensing signals are minor, a threshold value may be introduced to reduce unnecessary overhead. At least one threshold value may be semi-statically configured or dynamically indicated. For example, one threshold value may be configured or indicated for each configured parameter. Alternatively, one threshold value may be applied to all configured parameters. Here, the threshold value may be configured or indicated by an RRC configuration during the sensing measurement configuration. Alternatively, the threshold value may be conveyed by the sensing signal. For example, the threshold value may be predefined, configured, or indicated.

[0297] The initiator or transmitter transmitting the sensing signal needs to determine whether data to be reported exists based on a threshold value at the receiver side. An option is proposed for this purpose. The option involves using reporting information indicating whether data to be reported exists. The reporting information can be configured to have a minimum size. Furthermore, even if a minor change below the threshold is measured before the expiration of a predefined time interval, the sensing measurement data must be reported at least once.

[0298]

[0299] FIG. 16 illustrates an example of a procedure for reporting a difference in sensing measurement data based on a threshold value according to one embodiment of the present disclosure.

[0300] Referring to FIG. 16, in step S1601, the transmitter (1620) and the receiver (1610) form a single sensing group by performing a sensing group setup procedure. Here, the transmitter (1620) may be a base station, and the receiver (1610) may be a terminal. However, the present disclosure is not limited thereto.

[0301] In step S1603, the transmitter (1620) and the receiver (1610) perform a sensing measurement configuration setting procedure to set information required for sensing measurement. For example, the transmitter (1620) may transmit a sensing measurement configuration setting notification signal including sensing measurement configuration setting information to the receiver (1610). The sensing measurement configuration setting notification signal may include an SGID and an SMID. In addition, the sensing measurement configuration setting notification signal may include a threshold value for reporting.

[0302] In step S1605, the transmitter (1620) and the receiver (1610) perform a sensing measurement data generation and reporting procedure. The sensing measurement data generation and reporting procedure may be composed of a sensing signal transmission step (S1611, S1615, S1619) and a sensing measurement data reporting step (S1613, S1617, S1621).

[0303] Specifically, in step S1611, the transmitter (1620) transmits a first sensing signal. For example, the transmitter (1620) may transmit a first sensing signal having SGID=1, SMID=1, and SMI=1. At this time, the receiver (1610) performs a measurement on the sensing signal having SMI=1 and generates sensing measurement data based on the measurement result.

[0304] In step S1613, the receiver (1610) reports the first sensing measurement data with SMI=1 as a sensing measurement result for the first sensing signal. At this time, the transmitter (1620) may attempt to receive and / or detect the first sensing measurement result for the first sensing signal. FIG. 16 assumes that the transmitter (1620) successfully receives and / or detects the sensing measurement result for the first sensing signal with SMI=1.

[0305] In step S1615, the transmitter (1620) transmits a second sensing signal. For example, the transmitter (1620) transmits a second sensing signal having SGID=1, SMID=1, and SMI=2. At this time, the transmitter can transmit first information indicating whether the transmitter has successfully received a first sensing measurement result for the first sensing signal having SMI=1 using the second sensing signal. Here, the first information indicates that the transmitter has successfully received a sensing measurement result for the first sensing signal having SMI=1. The receiver (1610) performs a measurement for the second sensing signal having SMI=2 and generates second sensing measurement data based on the measurement result.

[0306] In step S1617, the receiver (1610) calculates a delta value, which is a difference between the first sensing measurement data and the second sensing measurement data, and compares the calculated delta value with a threshold value. If the delta value is greater than or equal to the threshold value, the receiver (1610) can report the delta value, which is a difference between the first sensing measurement data and the second sensing measurement data, to the transmitter (1620) as a sensing measurement result for the second sensing signal. That is, since the transmitter (1620) successfully receives the sensing measurement result for the first sensing signal and the difference between the first sensing measurement data and the second sensing measurement data is greater than or equal to the threshold value, the receiver (1610) can report the delta value, which is a difference between the first sensing measurement data and the second sensing measurement data, as a sensing measurement result for the second sensing signal.

[0307] In step S1619, the transmitter (1620) transmits a third sensing signal. For example, the transmitter (1620) transmits a third sensing signal having SGID=1, SMID=1, and SMI=3. The receiver (1610) performs a measurement on the third sensing signal having SMI=3 and generates third sensing measurement data based on the measurement result.

[0308] In step S1621, the receiver (1210) calculates a delta value, which is a difference between the second sensing measurement data and the third sensing measurement data, and compares the calculated delta value with a threshold value. If the delta value is less than the threshold value, the receiver (1610) can report to the transmitter (1620) at least the minimum information indicating that the difference between the second sensing measurement data and the third sensing measurement data is less than the threshold value as alternative sensing measurement data.

[0309] In the embodiment described with reference to FIG. 16, the receiver (1610) operating as a receiver reports the difference value as the sensing measurement data when the difference between the sensing measurement data for consecutive sensing signals is greater than or equal to a threshold value. On the other hand, when the difference value is less than the threshold value, the receiver (1610) may report minimal information to indicate that the difference between the sensing measurement data for consecutive sensing signals is negligibly small, or may not perform any reporting. This approach may be reasonable considering that most components of the sensing measurement data are likely to change due to large-scale channel effects.

[0310] In the embodiment described with reference to FIG. 16, the alternative sensing measurement data or the sensing measurement data may include components in which the difference between the sensing measurement data based on continuous sensing signals is less than or equal to a threshold value, equal to or greater than a threshold value. The alternative sensing measurement data or the sensing measurement data may further include sensing measurement data for specific components, and in the specific components, the difference value between the sensing measurement data based on continuous sensing signals may be equal to or greater than a threshold value.

[0311] If the difference between the sensing measurement data for consecutive sensing signals is less than a threshold, the difference between the sensing measurement data for consecutive sensing signals can be considered negligible. If the sensing measurement result is not reported in a situation where the difference between the sensing measurement data for consecutive sensing signals is negligible, the initiator or transmitter transmitting the sensing signal needs to determine what is wrong or has nothing to report based on the threshold on the receiver side. For this purpose, a time interval can be predefined, configured, or indicated. The receiver can notify the transmitter that there is no error by reporting the sensing measurement data at least once within the specified time interval.

[0312] FIG. 17 illustrates another example of a procedure for reporting differences in sensing measurement data based on threshold values ​​according to one embodiment of the present disclosure. Here, steps S1701 and S1703 are identical to steps S1601 and S1603 of FIG. 16 , and therefore, a description thereof is omitted.

[0313] Referring to FIG. 17, in step S1705, the transmitter (1720) and the receiver (1710) perform a sensing measurement data generation and reporting procedure. The sensing measurement data generation and reporting procedure may be composed of a sensing signal transmission step (S1711, S1715, S1719) and a sensing measurement data reporting step (S1713, S1717, S1721). Here, the transmitter (1720) may be a base station, and the receiver (1710) may be a terminal. However, the present disclosure is not limited thereto.

[0314] Specifically, in step S1711, the transmitter (1720) transmits a first sensing signal. For example, the transmitter (1720) may transmit a first sensing signal having SGID=1, SMID=1, and SMI=1. At this time, the receiver (1710) performs a measurement on the first sensing signal having SMI=1 and generates first sensing measurement data based on the measurement result.

[0315] In step S1713, the receiver (1710) reports the first sensing measurement data with SMI=1 as a sensing measurement result for the first sensing signal. At this time, the transmitter (1720) may attempt to receive and / or detect the sensing measurement result for the first sensing signal. FIG. 16 assumes that the transmitter (1620) successfully receives and / or detects the sensing measurement result for the first sensing signal with SMI=1.

[0316] In step S1715, the transmitter (1720) transmits a second sensing signal. For example, the transmitter (1720) transmits a second sensing signal having SGID=1, SMID=1, and SMI=2. At this time, the transmitter (1720) may transmit first information indicating whether a sensing measurement result for the first sensing signal having SMI=1 has been successfully received and / or detected to the receiver (1710). The first information may be transmitted using the second sensing signal. For example, the first information may indicate that a sensing measurement result for the first sensing signal having SMI=1 has been successfully received. The receiver (1710) performs a measurement for the second sensing signal having SMI=2 and generates second sensing measurement data based on the measurement result. The receiver (1710) calculates a delta value, which is a difference between the first sensing measurement data and the second sensing measurement data, and compares the calculated delta value with a threshold value. The receiver (1710) does not report the sensing measurement result for the second sensing signal if the delta value is less than the threshold value.

[0317] In step S1717, the transmitter (1620) transmits a third sensing signal. For example, the transmitter (1720) transmits a third sensing signal having SGID=1, SMID=1, and SMI=3. The receiver (1710) performs measurement on the third sensing signal having SMI=3 and generates third sensing measurement data based on the measurement result. The receiver (1710) calculates a delta value, which is a difference between the first sensing measurement data and the third sensing measurement data, and compares the calculated delta value with a threshold value. If the delta value is less than the threshold value, the receiver (1710) does not report the sensing measurement result for the third sensing signal.

[0318] In step S1719, the transmitter (1620) transmits an Nth sensing signal. For example, the transmitter (1720) transmits an Nth sensing signal where SGID=1, SMID=1, and SMI=N. The receiver (1710) performs a measurement on the Nth sensing signal where SMI=N and generates Nth sensing measurement data based on the measurement result. The receiver (1710) calculates a delta value, which is a difference between the first sensing measurement data and the Nth sensing measurement data, and reports the calculated delta value as a sensing measurement result for the third sensing signal. At this time, the receiver (1710) may report the delta value even if the delta value is less than a threshold value. This is to inform the transmitter that there is no error. In other words, the receiver (1710) can inform the transmitter (1720) that the reason why the sensing measurement result for at least one previous sensing signal was not received is because the difference between the sensing measurement data of consecutive sensing signals was less than a threshold value by transmitting the sensing measurement data to the transmitter (1720) at least once before the specified time interval expires regardless of the size of the delta value.

[0319] In the embodiment described with reference to FIG. 17, the time interval may be predefined, set, or indicated. Both the transmitter and receiver must know the value of the time interval. The transmitter may consider the transmission error-free if regular sensing measurement processes are performed during the time interval. For example, if at least one sensing measurement result is reported before the expiration of the time interval, the transmitter may consider the transmission error-free.

[0320] The value of the time interval can be set to a single value by a higher layer parameter, or can be set by a higher layer parameter to activate the corresponding capability. The value of the time boundary can be set to one or more values ​​by a higher layer parameter. To indicate the value of the time boundary, DCI or MAC CE can be used to dynamically indicate one of the predefined values, which are set by a higher layer parameter, or each fixed value with its own corresponding state.

[0321] According to one embodiment, a timer for time interval measurement may be defined as follows. The timer is started upon transmission of the first sensing signal. The timer starts from an initial value (e.g., 0) and may include a predefined offset value. Here, the predefined offset value may be separately included as an additional time offset in the sensing measurement configuration information. The predefined offset value may be configured by an RRC common or RRC terminal-specific parameter.

[0322] When reporting a sensing measurement result, a timer is stopped or reset to its initial value. Upon expiration of the timer, the transmitter may reset the timer to its initial value for the next corresponding operation. Alternatively, upon expiration of the timer, the transmitter may terminate the sensing configuration if a specific condition is met. For example, the transmitter may terminate the sensing measurement configuration if no sensing measurement result is received within a predefined, set, or indicated time interval or time period.

[0323]

[0324] In the present disclosure, a multi-base station and single terminal operation scenario may be additionally considered. Here, there may be one serving base station (BS) (1820, 1920) and multiple neighboring base stations (neighboring BS1, neighboring BS2) (1830-1, 1830-2, 1930-1, 1930-2) for the terminal (1810, 1910).

[0325] FIG. 18 illustrates an example of a sensing measurement process between multiple base stations and a single terminal according to one embodiment of the present disclosure.

[0326] Referring to FIG. 18, the serving base station (1820) can request the terminal (1810) to scan neighboring base stations and report scan result information. For example, the terminal (1810) can obtain information on neighboring base stations (1830-1, 1830-2) through scanning and report the obtained information on the neighboring base stations to the serving base station (1820). Based on the information reported from the terminal, the serving base station (1820) can coordinate sensing-related parameters for controlling and managing the terminal (1810) with the neighboring base stations (1830-1, 1830-2) through the X2 interface. Through this, the serving base station (1820) can request sensing measurement configuration-related information from the neighboring base stations (1830-1, 1830-2).

[0327] FIG. 19 illustrates another example of a sensing measurement process between multiple base stations and a single terminal according to one embodiment of the present disclosure.

[0328] Referring to FIG. 19, the terminal (1910) identifies the presence of multiple neighboring base stations (1930-1, 1930-2) that the terminal (1910) can listen to on the serving base station (1920). For example, the terminal (1910) can obtain information on the neighboring base stations (1930-1, 1930-2) and transmit the information to the serving base station (1920). Based on the information received from the terminal (1910), the serving base station (1920) can adjust sensing-related parameters with the neighboring base stations (1930-1, 1930-2) through the X2 interface in order to control and manage the terminal (1910). Through this, the serving base station (1920) can request sensing measurement configuration-related information from the neighboring base stations (1930-1, 1930-2).

[0329] As described with reference to FIGS. 18 and 19, various scenarios can be defined and related control information can be transmitted depending on the degree to which adjacent base stations intervene in the terminal during X2 interface communication.

[0330] Scenario 1: Weak involvement

[0331] The neighboring base station shares its sensing measurement configuration information with the serving base station via the X2 interface. For example, the sensing measurement configuration information may include information about at least one of a transmission time and a transmission target. The serving base station transmits its sensing measurement configuration information and information about the neighboring base station. In this scenario, the terminal can receive additional sensing signals from the neighboring base station and report sensing measurement data for the additional sensing signals to the serving base station.

[0332] Since these additional sensing signals are not targeted at the terminal, they may be missed or no longer transmitted. At this time, the terminal can measure the sensing signals from the serving base station and report the sensing measurement data to the serving cell.

[0333] Alternatively, during the sensing measurement process, if the terminal is unable to hear from at least one neighboring base station, the terminal may report its status to the serving base station. The status information may be added and / or augmented as a new component to the UCI. For example, the UCI may include the terminal's status information as a new component other than ACK / NACK, CSI, and SR. The status information may be added and / or augmented to the SR within the UCI. In this case, the terminal may only measure the sensing signal from the serving base station according to the sensing measurement configuration settings, and report the sensing measurement data to the serving base station.

[0334] Scenario 2: Strong involvement

[0335] The neighboring base station receives information from the serving base station that there is a terminal capable of listening to the neighboring base station through the X2 interface. The serving base station and the neighboring base station optimize parameters for the terminal by negotiating sensing measurement configuration information through the X2 interface. For example, the serving base station and the neighboring base station can negotiate at least one of the transmission timing and transmission target of the sensing signal. In this scenario, multiple base stations and terminals can be considered as a single sensing group.

[0336] During the sensing measurement process, if the terminal is unable to hear from at least one neighboring base station, the terminal may report its status to the serving base station. Status information may be added and / or augmented as a new component to the UCI. For example, the UCI may include terminal status information as a new component other than ACK / NACK, CSI, and SR. Status information may be added and / or augmented to the SR within the UCI.

[0337] The serving base station shares status information received from the terminal with its neighboring base stations. This allows the sensing measurement configuration to be completed.

[0338] In a multiple base station and terminal scenario, a sensing measurement process as illustrated in FIG. 20 may be performed based on a sensing measurement configuration set by a serving base station to support the aforementioned scenario. FIG. 20 illustrates another example of a sensing measurement process between multiple base stations and a single terminal according to an embodiment of the present disclosure.

[0339] Referring to FIG. 20, a serving base station (2020) and adjacent base stations (2030-1, 2030-2) transmit sensing signals toward a target. A terminal (2010) receives sensing signals reflected, refracted, or diffracted by the target and reports sensing measurement data for the sensing signals to the serving base station (2020). Here, the transmission time of the sensing signals may be set and / or instructed by the serving base station (2020). The reporting time, reporting method, or reporting target of the sensing measurement data for each sensing signal may be set and / or instructed by the serving base station (2020).
