Abstract
Description
TECHNICAL FIELD
[0001] The following description relates to a wireless communication system, and more particularly, to an apparatus and method for configuring a sensing group in a wireless communication system. BACKGROUND
[0002] Wireless access systems have been widely deployed to provide various kinds of communication services such as voice or data. Generally, a wireless access system is a multiple access system that supports communication of multiple users by sharing available system resources (bandwidth, transmission power, etc.) among them. For example, multiple access systems include code division multiple access (CDMA) systems, frequency division multiple access (FDMA) systems, time division multiple access (TDMA) systems, orthogonal frequency division multiple access (OFDMA) systems, and single carrier frequency division multiple access (SC-FDMA) systems.
[0003] Specifically, since a large number of communication devices require a large communication capacity, an enhanced mobile broadband (eMBB) communication technology is proposed compared to a conventional radio access technology (RAT). In addition, not only a massive machine type communication (massive MTC) that provides various services anytime and anywhere by connecting multiple devices and objects is proposed, but also a communication system that considers services / UEs sensitive to reliability and latency is proposed. For this, various technical configurations are proposed. SUMMARY

[0045] The embodiments of this disclosure described below are combinations of the structural elements and features of this disclosure in a specific manner. Unless otherwise stated, elements or features may be considered selective. Each element or feature may also be practiced without combination with other elements or features. Furthermore, embodiments of this disclosure may be constructed by combining some elements and / or features. The order of operations described in the embodiments of this disclosure may be rearranged. Some constructions or elements of any embodiment may be included in another embodiment and may be replaced by corresponding constructions or features of another embodiment.
[0046] In the description of the accompanying drawings, processes or steps that would unnecessarily obscure the scope of this disclosure will be omitted, as will processes or steps that would be understandable to those skilled in the art.
[0047] Throughout the specification, when a part "comprises" or "includes" a component, this indicates that other components are not excluded and may be included unless otherwise specified. The terms "unit," "device," and "module" described in the specification indicate a unit for performing at least one function or operation, which may be implemented by hardware, software, or a combination thereof. Furthermore, unless otherwise indicated in this specification or unless clearly indicated in the context, in the context of this disclosure (more specifically, in the context of the appended claims), related terms such as "a or an," "the," etc., may include both singular and plural expressions.
[0048] In the embodiments of this disclosure, the relationship between data reception and transmission between a base station (BS) and a mobile station is mainly described. A BS refers to a terminal node in the network that communicates directly with the mobile station. Specific operations described as being performed by the BS can be performed by upper-layer nodes of the BS.
[0049] That is, it is clear that in a network consisting of multiple network nodes including a BS, various operations performed for communicating with a mobile station can be performed by the BS or network nodes other than the BS. In this document, "BS" can be replaced by terms such as "fixed station", "node B", "evolved node B (eNode B or eNB)", "advanced base station (ABS)" or "access point".
[0050] In embodiments of this disclosure, the term "terminal" may be replaced by terms such as "UE", "mobile station (MS)", "mobile subscriber station (MSS)", "mobile terminal" or "advanced mobile station (AMS)".
[0051] The sender is a fixed and / or mobile node that provides data or voice services, and the receiver is a fixed and / or mobile node that receives data or voice services. Therefore, on the uplink (UL), the mobile station can act as the sender, and the BS can act as the receiver. Similarly, on the downlink (DL), the mobile station can act as the receiver, and the BS can act as the sender.

As another example, the memory device may be configured with RAM, dynamic RAM (DRAM), ROM, flash memory, volatile memory, non-volatile memory, and / or combinations thereof.
[0084] This disclosure applies to 5G system architectures.
[0085] 5G systems are advanced technologies derived from 4G LTE mobile communication technology and support new radio access technologies (RATs), extended long-term evolution (eLTE) as an extension of LTE, and non-3GPP access (e.g., wireless local area network (WLAN) access) through the evolution of existing mobile communication network architectures or net-state architectures.
[0086] Defining 5G systems based on services, and the interactions between network functions (NFs) in the architecture of 5G systems can be represented in the following two ways.
[0087] - Reference point representation: Indicates the interaction between NF services in an NF described by a point-to-point reference point (e.g., N11) between two NFs (e.g., AMF and SMF).
[0088] - Service-based representation: Network functions within the control plane (CP) (e.g., AMF) allow other authenticated network functions to access their services. This representation may also include point-to-point reference points if needed.
[0089] The 5G core (5GC) may include various components including Access and Mobility Management Function (AMF), Session Management Function (SMF) 420, Policy Control Function (PCF), Prose User Plane Function (UPF), Application Function (AF), Unified Data Management (UDM), and Non-3GPP Interoperability Function (N3IWF).
[0090] The UE connects to the data network via a UPF through a next-generation radio access network (NG-RAN) including a gNB. Data services can be provided to the UE even through untrusted, non-3GPP access (e.g., a wireless local area network (WLAN)). To connect non-3GPP access to the core network, an N3IWF can be deployed.
[0091] The N3IWF manages interoperability between non-3GPP access and 5G systems. When a UE connects to a non-3GPP access (e.g., WiFi known as IEEE 801.11), the UE can connect to the 5G system via the N3IWF. The N3IWF performs control signaling with the AMF and connects to the UPF via the N3 interface for data transmission.
[0092] AMF can manage access and mobility in 5G systems. AMF can perform functions to manage (non-access stratum) NAS security. AMF can perform functions to handle mobility in idle states.
[0093] UPF performs gateway functions for sending and receiving user data. A UPF node can perform all or part of the user plane functions of a Serving Gateway (S-GW) and Packet Data Network Gateway (P-GW) for 4G mobile communications.
[0094] The UPF serves as a boundary point between the Next Generation Radio Access Network (NG-RAN) and the core network, and is a component that maintains the data path between the gNB and the SMF. Additionally, the UPF acts as a mobility anchor point when the UE moves within an area served by the gNB. The UPF can perform the function of disposing of PDUs. For mobility within the NG-RAN (defined after 3GPP Release 15), the UPF can route packets. Furthermore, the UPF can also serve as an anchor point for mobility with another 3GPP network (RANs defined before 3GPP Release 15, such as Universal Mobile Telecommunications System (UMTS) Terrestrial Radio Access Network (UTRAN), Evolved (E)-UTRAN, or Global System for Mobile Communications (GERAN) / Enhanced Data Rate Global Evolution (EDGE) RAN). The UPF can correspond to an endpoint of the data interface toward the data network.
[0095] PCF is the node that controls the operator's policies. AF is the server used to provide various services. UDM is the server that manages subscriber information (e.g., the Home Subscriber Server (HSS) for 4G mobile communications). UDM stores and manages subscriber information in the Unified Data Repository (UDR).
[0096] The SMF can perform the function of allocating Internet Protocol (IP) addresses to UEs. In addition, the SMF can control Packet Data Unit (PDU) sessions.
[0097] For ease of explanation, the reference numerals for AMF, SMF, PCF, UPF, AF, UDM, N3IWF, gNB, or UE may be omitted in the following text. These reference numerals can be referenced to the descriptions in the standard documents previously published for this purpose.
[0098] Figure 3 This is a diagram illustrating an example of the functional separation of NG-RAN and fifth-generation core (5GC) applicable to this disclosure.
[0099] Reference Figure 3 The UE connects to the data network (DN) via the next-generation RAN. Control plane function (CPF) nodes perform all or part of the functions of the mobility management entity (MME) for 4G mobile communications, as well as all or part of the functions of the serving gateway (S-GW) and PDN gateway (P-gateway). CPF nodes include the AMF and SMF.
[0100] UPF nodes function as gateways that send and receive user data.

[0104] The radio interface protocol is based on the 3GPP radio access network standard. Horizontally, the radio interface protocol is divided into the physical layer, data link layer, and network layer; vertically, it is divided into the user plane for transmitting data information and the control plane for sending control signals (signaling).
[0105] Based on the three lower layers of the widely known Open Systems Interconnection (OSI) reference model in communication systems, the protocol layer can be divided into L1 (layer 1), L2 (layer 2), and L3 (layer 3).
[0106] In the following sections, each layer of the radio protocol is described. Figure 4 This is an example illustrating a general architecture applicable to 5G (5th generation) systems of this disclosure.
[0107] Reference DETAILED DESCRIPTION The access layer (AS) may include the physical (PHY) layer, medium access control layer, radio link control (RLC) layer, packet data convergence protocol (PDCP) layer, and radio resource control (RRC) layer, and operations based on each layer can be performed with reference to the descriptions in the standard documents previously published in this document.
[0108] Figure 5
[0109] This disclosure relates to apparatus and method for dynamically configuring sensor groups in a wireless communication system. Specifically, this disclosure relates to a method and apparatus for dynamically configuring a sensor group by having a sensing initiator select at least one sensor group from pre-configured sensor groups in a network and join the selected at least one sensor group.
[0110] Next-generation wireless communication is considered a key driver for various emerging fields such as smart cities, industrial IoT, eHealth, automotive, public safety, and education. Sensing capabilities supporting applications in these emerging fields are seen as crucial in meeting the demand for high-quality services based on the accuracy of sensing the surrounding environment. Therefore, it is natural to discuss sensing-related functions, technologies, and capabilities in both cellular and Wi-Fi networks.
[0111] In the following, within this disclosure, 5G wireless sensing can be defined as a 5GS function that provides the ability to obtain information about the environment using NR radio frequency (RF) signals and / or characteristics of objects within the environment (e.g., the shape, size, orientation, speed, position, distance, or relative movement between objects), and in some cases, the ability to obtain predefined information available in EPC and / or E-UTRA. Additionally, a sensing group can be defined as a set including at least one sensing transmitter and at least one sensing receiver, the locations of which are known and sensing data can be collected synchronously. Sensing results can refer to processed 3GPP sensing data requested by a service consumer, and sensing signals can refer to transmitted signals on the 3GPP radio interface used for sensing. These definitions refer to NR RF signals and predefined information available in EPC and / or E-UTRA can be used without affecting EPC and / or E-UTRA.
[0112] This disclosure describes a sensing measurement process for collecting sensing measurement data. Sensing measurement data refers to data collected based on radio / wireless signals affected by reflection, refraction, or diffraction of the target of interest or the environment used for sensing purposes. In the following, sensing measurement data may be used and / or interpreted as indicating 3GPP sensing data and / or non-3GPP sensing data. Information derived from the sensing measurement data refers to the sensing result. Furthermore, to clarify the sensing measurement process, four components are defined below (i.e., sensing initiator, sensing responder, sensing transmitter, and sensing receiver).
[0113] - Sensing Initiator: The sensing initiator is the entity that initiates the sensing measurement process and can be a base station, UE, or CPE.
[0114] - Sensing Response Entity: A sensing response entity is an entity that participates in the sensing measurement process in response to a sensing initiator, and can be a base station, UE, or CPE.
[0115] - Sensing Sender: The sensing sender is the entity that transmits sensing signals for the operation of the sensing service, and can be an NR RAN node or a UE. The sensing sender can be the same entity as the sensing receiver, or it can be a different entity. Additionally, the sensing sender can be a base station, UE, or CPE that transmits sensing signals to be measured during the sensing measurement process.
[0116] - Sensing Receiver: A sensing receiver is an entity that receives sensing signals for operation used in sensing services, and can be an RN RAN node or a UE. The sensing receiver can be the same entity as the sensing sender or a different entity. Alternatively, the sensing receiver can be a base station, UE, or CPE that receives sensing signals transmitted from the sensing sender and obtains sensing measurement data during the sensing measurement process.
[0117] In this disclosure, each of the sensing initiator, sensing responder, sensing sender, and sensing receiver may be referred to as the initiator, responder, sender, and receiver, respectively.
[0118] The location or service area used for the sensing measurement process can include a target sensing service area and a moving target sensing service area. A target sensing service area refers to a Cartesian location area sensed by deriving characteristics of an environment and / or objects within that environment with a specific sensing service quality from wireless signals that have already been affected (e.g., refraction, reflection, diffraction). Here, the target sensing service area can include both indoor and outdoor environments. Conversely, a moving target sensing service area refers to a target sensing service area that moves from the perspective of the sensing transmitter according to the movement of the target.
[0119] During the sensing measurement process, a device (e.g., a base station, UE, or CPE) can act as an initiator, responder, transmitter, and / or receiver. A device acting as a sensing initiator can initiate the sensing measurement process via a downlink shared channel (DSCH), physical downlink control channel (PDCCH), physical uplink shared channel (PUSCH), physical uplink control channel (PUCCH), or sidelink shared channel (SL-SCH). A device that has initiated the sensing measurement process as a sensing initiator can operate as at least one of a sensing transmitter or a sensing receiver, or may not operate as either a sensing transmitter or a sensing receiver. A device acting as a sensing initiator can access sensing measurement data and can transmit the sensing measurement data to a service provider or service consumer via the network, or can directly derive the sensing results. A device acting as a sensing responder can participate in the sensing measurement process via PDSCH, PDCCH, PUSCH, PUCCH, or SL-SCH, and can act as at least one of a sensing transmitter or a sensing receiver. A device acting as a sensing receiver can access measurement data. The device acting as a sensing transmitter can transmit sensing signals affected by the object of interest or the sensing environment (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), or Sounding Reference Signal (SRS)). When permitted, non-3GPP signals (e.g., radar signals) can be used as sensing signals. When high spectral efficiency is preferred during the sensing measurement process, OFDM, Discrete Fourier Transform-Extended-OFDM (DFT-S-OFDM), or modifications thereof can be used as sensing signals. The device acting as a sensing receiver can receive affected sensing signals and, if necessary, report sensing measurement data (e.g., PDSCH, PUSCH, SL-SCH, etc.) to the sensing initiator. The device operating as a sensing receiver can access the sensing measurement data. Based on the topology or architecture defined in 3GPP, the sensing initiator and sensing transmitter can be the same device. Similarly, the sensing responder and sensing receiver can be the same device.
[0120] Figure 6 An example of a sensing measurement process according to the role of the apparatus applicable to this disclosure is illustrated, and Figure 5 Another example of a sensing measurement process based on the role applicable to the apparatus of this disclosure is illustrated.
[0121] Reference Figure 6In this configuration, base station 520 operates as both a sensing initiator and a sensing transmitter, while UEs 510-1 and 510-2 operate as both sensing responders and sensing receivers. In this configuration, base station 520, acting as the sensing initiator, is configured with a sensing group consisting of UEs 510-1 and 510-2 acting as sensing responders, and base station 520, acting as the sensing transmitter, transmits signals for sensing. Each of UEs 510-1 and 510-2, acting as sensing receivers, receives signals reflected from a target and transmits sensing measurement data generated based on the received signals to base station 520 as a sensing result.
[0122] Reference Figure 7 In this configuration, base station 620 operates as both a sensing initiator and a sensing receiver, first UE 610-1 operates as both a sensing responder and a sensing transmitter, and second UE 610-2 operates as both a sensing responder and a sensing receiver. In this case, base station 620, acting as the sensing initiator, is configured with a sensing group consisting of UEs 610-1 and 610-2 acting as sensing responders. When the sensing group is configured, first UE 610-1, acting as the sensing transmitter, transmits a signal for sensing. Each of second UE 610-2, acting as the sensing receiver, and base station 620 receives a signal reflected from a target. Base station 620 stores sensing measurement data generated based on the received signals as a sensing result, and second UE 610-2 transmits the same sensing measurement data to base station 620 as a sensing result.
[0123] Figure 7 Examples of specific steps in the sensing measurement process applicable to this disclosure are illustrated. (Refer to...) Sensing group configuration The sensing and measurement process can consist of the following steps.
[0124] Sensing Group (SG) Establishment Phase S701: The sensing group configuration phase S701 is the phase in which the sensing initiator and sensing responder form a sensing group, and updates to the sensing group can be performed when necessary. For example, an existing sensing group can be changed when necessary.
[0125] Sensing Measurement Configuration (SMC) Configuration Phase S703: The sensing measurement configuration phase S703 is the phase for configuring the information required for sensing measurements of the sensing transmitter and / or sensing receiver within the sensing group, and updates to the sensing measurement configuration can be performed if necessary.
[0126] Sensing Measurement Data (SMD) Generation and Reporting Stage S705: The sensing measurement data generation and reporting stage S705 includes the sensing signal transmission stage S711 of the sensing sender, the sensing measurement data generation stage S713 of the sensing receiver, and the sensing measurement data reporting stage S715 of the sensing receiver.
[0127] Sensing Measurement Configuration Termination Stage S707: The sensing measurement configuration termination stage S707 is the stage that terminates the sensing measurement configuration after the sensing measurement is completed.
[0128] Sensing group termination stage S709: The sensing group termination stage S709 is the stage that terminates the sensing group after the sensing measurement configuration is terminated.
[0129] At least some of the steps in the sensing measurement process described above can be repeated. For example, the sensing measurement data generation and reporting phase S705 can be repeated. As another example, the sensing group establishment phase S701 and the sensing measurement configuration phase S703 can be designed to be performed once. If necessary, at least one of the sensing group update or sensing measurement configuration update can be repeated once or more. For example, to update the sensing measurement configuration, the sensing measurement configuration phase S703 can be repeated.
[0130] When different devices are in different modes relative to the sensing initiator (e.g., sensing idle mode or sensing active mode), the sensing initiator can consider two conditions before starting the sensing measurement process. In this disclosure, each of the idle mode and active mode can be understood as a sensing idle mode relative to the sensing initiator and a sensing active mode relative to the sensing initiator. A UE operating in idle mode relative to sensing initiator A can operate in active mode relative to another sensing initiator.
[0131] Depending on the type of sensing measurement process, during the idle mode of the sensing responder, each candidate responder or potential responder may perform periodic wake-ups and monitoring to check for the presence of data to be received from the first sensing initiator. Alternatively, each candidate responder or potential responder may operate in a completely idle state relative to the first sensing initiator, so as not to expect to receive data from the first sensing initiator while monitoring, measuring, or receiving data from a second sensing initiator that has completed another sensing group establishment. That is, a sensing responder may operate in an idle mode relative to the first initiator and in an active mode relative to the second initiator or responder. When a candidate responder is in an active mode, the sensing initiator transmits information for a predefined duration and may transmit this information via a control channel (e.g., Physical Downlink Control Channel (PDCCH), Sidelink Control Channel (SLCCH)). In this case, the candidate responder participates in the sensing measurement process when the information indicates the presence of data to be received. Assuming an active link has been configured between the sensing initiator and the sensing responder, the sensing initiator can obtain information corresponding to the link quality from potential responders (e.g., interference information based on Channel State Information Reference Signal (CSI-RS) and CSI for Interference Management (CSI-IM), as well as channel state information). Before participating in the sensing measurement process, the initiator can perform a process to obtain link quality from candidate responders. The sensing activity mode can be configured semi-statically or dynamically via RRC, MAC CE, or DCI, based on information about the time and location for switching to the sensing activity mode or based on a specific mode (e.g., duty cycle).
[0132] Sensing measurement configuration settings
[0133] The sensing initiator may send a sensing group establishment request message, which may include a first sensing group establishment ID. The sensing group establishment ID may be co-encoded with a portion of the establishment request message (e.g., a CRC scrambled with the sensing group establishment ID). The sensing group establishment request message may include a minimum number of responders. The minimum number of responders can be configured via RRC parameters (e.g., RRC common parameters or RRC UE-specific parameters). Subsequently, when the base station participates in the sensing measurement process as a responder, RRC UE-specific parameters (e.g., RRC responder / receiver parameters) for the base station can be used and / or interpreted. In this case, when no threshold indicating the minimum number of responders is defined, the minimum number of responders may be considered as 1 or a specific value. The sensing group configuration request message may include capability information required by the sensing responders. The required capability information can be configured via RRC parameters (e.g., RRC common parameters or RRC UE-specific parameters). The sensing group configuration request message may be retained as is until the sensing group is terminated by the sensing initiator or sensing responder. Parameters configured via RRC common parameters or RRC UE-specific parameters can be retained as is until the sensing group is terminated by the initiator or responder.
[0134] In response to a sensing group configuration request message including a first sensing group configuration ID, the sensing responder sends sensing group configuration response information. The sensing group configuration response information can be sent using a first type of DCI format. The first sensing group configuration ID can be CRC scrambled in the first type of DCI. The sensing group configuration response information may include information indicating the responder's participation status. The responder's participation status may include participation acceptance, participation rejection, or an adjustment status indicating that participation is possible under specific conditions. The sensing group configuration response information may be sensing group configuration-related information sent by a responder expected to withdraw from or terminate participation in the sensing group. When an adjustment status is received from a responder with specific conditions, the sensing initiator determines whether to accept the adjusted status.
[0135] When necessary, the sensing initiator can check whether the number of sensing responders wanting to participate in the sensing group is equal to or greater than a first threshold. The first threshold can be configured as a minimum number of responders. The first threshold can be a fixed value or one of a predefined set of values. The predefined set can be configured differently based on the environment of interest or the sensing object being sensed. When there is no predefined threshold for a minimum number of responders, the threshold can be considered as 1. As described above, when various values configured for a first duration are given, if the number of sensing responders is less than the first threshold, the initiator waits until the longest value among the values within the first duration.
[0136] The sensing initiator sends sensing group configuration completion information with a first sensing group configuration ID to one or more responders who have responded in an accepted or adjusted state. When the number of responders is equal to or greater than a first threshold, the sensing initiator selects the responders to whom it will send sensing group configuration completion information.
[0137] - When negotiation of the corresponding link between the initiator and the responder is completed, a sensing group configuration completion message can be sent. In this case, the sensing group configuration completion message can be sent from either the initiator or the responder.
[0138] - A sensing group configuration completion message can be sent when all negotiations between the initiator and the responder are complete. In this case, the initiator can send a sensing group configuration completion message when all negotiations between the initiator and the responder are complete.
[0139] Negotiation of the sensing group configuration between the initiator and responder can be processed within a specific time interval. In this case, the specific time interval can be included in the first sensing group configuration request message with a first configuration ID. This specific time interval can be configured by RRC common parameters or RRCUE specific parameters. The sensing group configuration completion message should be sent within the specific time interval.
[0140] The initiator completes the sensor group configuration process and proceeds to the next stage of the sensing measurement process together with the responders who have already completed the sensor group configuration process.
[0141] - For additional operations related to the sensor group configuration, the initiator can update the responder information for the targeted sensor group using the first sensor group configuration ID. One or more responders can join or leave the sensor group for any reason. When the number of responders is equal to or greater than a first threshold, all request-response-completion processes described above do not need to be repeated.
[0142] - For additional operations related to sensor group configuration, a sensor group configuration using a second sensor group configuration ID can begin before a sensor group using a first sensor group configuration ID terminates. In this case, a responder can participate in one or more sensor groups.
[0143] - When the number of responders is less than the first threshold, the initiator terminates the sensing group configuration.
[0144] Sensing measurement data generation and reporting
[0145] After successful sensor group configuration, perform sensor measurement configuration setup. Sensor measurement configuration setup begins by sending a sensor measurement configuration setup notification message to users of the sensor group involved in the sensor group configuration phase via multicast or unicast.
[0146] The sensing measurement configuration setting notification information may include a sensing group configuration 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 jointly encoded together with a portion of the sensing measurement configuration setting notification information (e.g., a CRC scrambled with the first sensing measurement configuration setting ID). When a sensing measurement configuration setting ID is assigned to a sensing group, the notification information can be retained as is until the corresponding sensing measurement configuration is terminated.
[0147] The sensing measurement configuration setting announcement information may include the type of sensing measurement data to be measured. The sensing measurement data may be channel state information (e.g., average SNR-related information and 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 RRC parameters (e.g., RRC common parameters or RRC UE-specific parameters). The type of sensing measurement data may be transmitted 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 configuration setting ID may be assigned to one sensing measurement data. For example, sensing measurement configuration setting IDs may be assigned as a group to one or more sensing measurement data. Furthermore, the set of sensing measurement data may be configured differently depending on the purpose. For example, in the case of sensing measurement configuration for a sidelink, it may be necessary to assign a subset of sensing measurement data to the downlink.
[0148] The sensing measurement configuration settings notification information can include information about the frequency at which sensing measurement data is generated. For example, the measurement interval for each sensing measurement data can be configured, and different sensing measurement data can be measured at different intervals.
[0149] The sensing measurement configuration settings notification information can include the reporting frequency and / or content of sensing measurement data. For example, the reporting interval for each measurement data can be configured, and different sensing measurement data can be reported at different intervals. When reporting sensing measurement data, the sensing measurement data can be the most recently measured sensing measurement data. The reported sensing measurement data can include the average of one or more sensing measurement data.
[0150] When a sensing measurement configuration setting notification is received, the responder who has participated in the sensing measurement process during the sensing group configuration can send a sensing measurement configuration setting completion message in response to the sensing measurement configuration setting notification.
[0151] - The initiator can check whether the responder has correctly received the corresponding sensor measurement configuration information. The responder's sending of the sensor measurement configuration setup completion message indicates that the responder has accepted the parameters configured for the sensor measurement configured by the initiator.
[0152] The sensing measurement configuration setting response information may include information indicating at least one of an accept state, a reject state, or an adjustment state. The sensing measurement configuration setting response information can be transmitted via a third type of DCI format. The first sensing measurement configuration setting ID can be CRC scrambled in a third type of DCI format. The accept state indicates that the parameters for the sensing measurement configuration configured by the initiator have been accepted, and the reject state indicates that the parameters for the sensing measurement configuration configured by the initiator have been rejected. Additionally, the adjustment state indicates negotiation of the parameters for the sensing measurement configuration configured by the initiator. Here, for better perception in mobility situations, the responder can propose one or more parameters for sensing measurements via the sensing measurement configuration setting response information.
[0153] - The initiator may send a sensing measurement configuration setup completion message to one or more responders. For example, sending a sensing measurement configuration setup completion message to a responder in the accept state means that the initiator has acknowledged that the responder has accepted the parameters for the sensing measurement configuration configured by the initiator. As another example, sending a sensing measurement configuration setup completion message to a responder in the adjust state means that the initiator has accepted the parameters for the sensing measurement configuration configured by the responder. Alternatively, sending a sensing measurement configuration setup completion message to a responder in the reject state means that the initiator has acknowledged that the responder has rejected the parameters for the sensing measurement configuration configured by the initiator and that the responder has not yet proposed configuration parameters. To save resource elements, the initiator may choose not to send a sensing measurement configuration setup completion message to a responder in the reject state.
[0154] Additional negotiation can be performed to configure configuration parameters for sensing measurements between the initiator and the responder.
[0155] - Once negotiation for each corresponding link between the initiator and responder is complete, a sensing measurement configuration setup completion message can be sent. This message can be sent from either the initiator or the responder.
[0156] - Once all negotiations between the initiator and the responder are complete, a sensing measurement configuration setup completion message can be sent. The initiator can send this message once all negotiations between the initiator and the responder are complete.
[0157] Additional operations related to the sensing measurement configuration settings allow the initiator to update sensing measurement configuration information. Within one or more sensing measurement configurations for sensing measurement data, the measurement time interval can be updated to a new measurement time interval. In this case, the remaining configuration for the sensing measurement data is preserved as is. Similarly, within one or more sensing measurement configurations for sensing measurement data, the reporting time interval can be updated to a new reporting time interval. In this case, the remaining configuration for the sensing measurement data is preserved as is.
[0158] For additional operations related to sensing measurements, a sensing measurement configuration setting using a second sensing measurement configuration setting ID can be started before terminating the sensing measurement using the first sensing measurement configuration setting ID. A responder can participate in one or more sensing measurement configuration settings.
[0159] Figure 7
[0160] After successfully executing the sensor measurement configuration settings, perform sensor measurement data generation and reporting. For example... Figure 8 As shown, some steps of the sensing measurement process (i.e., the sensing measurement data generation and reporting phase) can be repeated.
[0161] Once the sensor group configuration and sensor measurement configuration settings are complete, the sender transmits a sensor signal. Additionally, two or more senders can transmit sensor signals. The receiver or initiator can trigger one or more senders to transmit sensor signals. The receiver measures and reports the transmitted sensor signals according to the configuration pre-configured during the sensor measurement configuration setup.
[0162] exist Figure 8 The example signaling used for setting up sensing measurement configuration and generating and reporting sensing measurement data is illustrated in the figure. Figure 8 An example of a sensing measurement data generation and reporting process based on sensing measurement configuration settings applicable to this disclosure is illustrated. Sensing measurement configuration terminationEach of the sender 820 and / or receivers 810-1, 810-2, and 810-3 shown can be a UE, a base station, or another network entity. For example, sender 820 can be a base station, and receivers 810-1, 810-2, and 810-3 can be UEs. Sender 820 can be an initiator, and the first receiver 810-1, the second receiver 810-2, and / or the third receiver 810-3 can be potential or confirmed responders. Sender 820 can perform step 1, a sensing group configuration phase S80, to configure the sensing group using the first receiver 810-1. When the sensing group configuration is complete, sender 820 and the first receiver 810-1 participate in the sensing measurement process. That is, sender 820 and the first receiver 810-1 can repeatedly perform the sensing measurement configuration setup phases S803, S807, and S811, and the sensing measurement data generation and reporting phases S805, S809, and S813. After successfully generating and reporting the sensed measurement data, you can terminate the sensed measurement configuration or the sense group. Typically, termination can be performed explicitly or implicitly by the initiator or responder.
[0163] Sensing group termination
[0164] Sensing measurement configuration termination can be performed implicitly or explicitly. For example, sensing measurement configuration termination can be performed after a predefined duration of implicit waiting for expected information, or it can be performed by explicitly indicating the termination of the sensing measurement configuration based on first information. The first information may include at least one of a sensing measurement configuration setting ID or a sensing group configuration ID. In this case, the same sensing measurement configuration setting ID and different sensing group IDs can be assigned. The initiator can terminate the sensing measurement configuration simultaneously for all participants in the sensing group. The initiator can terminate one or more sensing measurement configurations for one or more specific responders. One or more responders can terminate their own sensing measurement configurations. The first information may include a sensing measurement configuration setting ID set to a specific value (e.g., F) to indicate the termination of all sensing measurement configurations, independent of the sensing measurement configuration setting ID.
[0165] Figure 9
[0166] Sensing group termination can be performed implicitly or explicitly. For example, it can be performed after a predefined duration of implicit waiting for expected information, or it can be performed using first information indicating the termination of the sensing group. The predefined duration can be configured by RRC common parameters or RRC UE-specific parameters. The first information may include the sensing group configuration ID. A sensing group can be terminated simultaneously for all participants by an initiator. A sensor group can be terminated 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 may include a sensing group configuration ID configured to a specific value (e.g., F) to indicate the termination of all sensing groups, independent of the corresponding sensing group configuration ID.
[0167] In 3GPP, downlink control information (DCI) can send information such as hybrid automatic repeat and request (HARQ) messages for uplink and downlink, physical layer resource allocation, and power control commands.
[0168] - Send information for resource scheduling against PDSCH
[0169] - Send information for resource scheduling for PUSCH.
[0170] - Send information for PUSCH and PUCCH power adjustments for UL power control.
[0171] DCI is transmitted via PDCCH with a 24-bit CRC. To meet various requirements and conditions, multiple DCI formats are defined, and NR DCI formats can share the same DCI size for efficient implementation.
[0172] In 3GPP, the Physical Uplink Control Channel (PUCCH) is the uplink physical channel for transmitting Uplink Control Information (UCI). Directed Downlink Control Information (DCI) is transmitted via the Physical Downlink Control Channel (PDCCH), and UCI is transmitted via the PUCCH. The main difference between DCI and UCI is that, depending on the situation, UCI can be transmitted via either PUCCH or PUSCH, while DCI can be transmitted via PDCCH only. DCI is never transmitted via PDSCH. UCI is reported to the network via the uplink physical channel (i.e., PUCCH or PUSCH). UCI may include at least one of HARQ ACK / NACK, Scheduling Request (SR), or CSI. For example, depending on the situation, UCI may include only one of HARQ ACK / NACK, SR, or CSI, or it may include at least two or more of HARQ ACK / NACK, SR, or CSI. HARQ ACK / NACK, SR, or CSI are not transmitted via a single UCI. UCI is encoded and transmitted via PUCCH or multiplexed via PUSCH. CSI reporting configuration can be executed non-periodically via PUSCH, periodically via PUCCH, or semi-persistently via PUCCH or DCI-activated PUSCH.
[0173] In this disclosure, new or modified information related to the sensing measurement process (e.g., SGID, SMID, SMI, or sensing measurement data related information) may be carried along with the UCI as described above via PUCCH and / or PUSCH.
[0174] 3GPP has not yet discussed how a sensing initiator can configure sensing groups (e.g., sensing groups including those of the responder) in a sensing system to initiate a sensing measurement process. Therefore, this disclosure proposes a method for configuring sensing groups to initiate a sensing measurement process, in which a base station, network node, and / or service provider pre-configures sensing groups (i.e., a set of sensing groups). Specifically, this disclosure proposes a method and apparatus in which a base station, network node, and / or service provider pre-configures a set of sensing groups, and a sensing initiator selects at least one sensing group from the pre-configured set of sensing groups to perform a sensing measurement process.
[0175] A pre-configured set of sensor groups can include N sensor groups. Each sensor group can include one or more initiators and / or one or more responders. When the set of sensor groups is pre-configured, the initiator does not need to perform additional processes for configuring the sensor groups or for finding devices to be included in the sensor groups in order to begin the sensing measurement process. For example, the initiator can select at least one sensor group from the pre-configured sensor groups based on some criteria, conditions, or circumstances. In this way, the sensing measurement process can be performed simply and efficiently.
[0176] Each sense group within a sense group set can be assigned an index. For example, a first index can be assigned to a first sense group, and a second index can be assigned to a second sense group. The index assigned to each sense group can be used as the sense group's ID. When a sense group set is configured, the sense groups with assigned indexes can be notified or exposed to the initiator and / or responder. The sense group set can be configured by RRC and may require defining some parameters for the sense measurement process.
[0177] According to existing technology, a sensing initiator needs to request at least one other device (e.g., a responder) to configure a sensing group for the sensing initiator. In contrast, according to one embodiment of this disclosure, a sensing initiator can participate in at least one selected sensing group by selecting at least one sensing group from a pre-configured set of sensing groups without requesting at least one other device to configure the sensing group. Here, participating in a sensing group may include performing an authentication process at the sensing initiator.
[0178] To enable the initiator to dynamically indicate sensing groups, existing or new types of DCI and / or UCI used for the sensing measurement process may include an index of at least one sensing group in the configured set of sensing groups. In multi-cell or multi-band applications, dedicated types of DCI and / or UCI for the sensing measurement process may be used. Alternatively, for dynamic indication, the MAC CE may transmit the index of at least one sensing group in the configured set of sensing groups.
[0179] Predefined or configured sense groups set at a specific point in time, for a specific duration, or during a time interval can be reconfigured for any reason. That is, new sense group sets can be generated and configured. According to one implementation, sense group sets can be reconfigured based on RRC configuration parameters (e.g., a specific duration). According to one implementation, sense group sets can be reconfigured non-periodically based on events driven by specific conditions. Here, the event can be specified as a condition, and a new sense group set is configured when the condition of the event is met. For example, the condition could be a degradation in sense performance during a specific duration (e.g., a degradation percentage), a high percentage of sense groups with a size less than a first threshold, or a situation where members of the current sense group are assessed as being outside the cell, outside the service area, or outside the service duration.
[0180] When a device belonging to a specific sensing group receives information about a new set of sensing groups, it can terminate the inclusion of that specific sensing group in an outdated set of sensing groups.
[0181] Various options exist for generating a set of sensor groups. Here, the device uses the concept of a set to associate with at least one sensor group that already exists and is exposed to or identified by the device. The device uses the set of sensor groups to facilitate the selection of the most suitable candidate sensor group for association, and the device can obtain sensing-related data or sensing services by associating with the selected sensor group.
[0182] Figure 9 An example of a sensor group set according to one embodiment of the present disclosure is illustrated.
[0183] Reference Figure 10 The responder can belong to at least one of the multiple sensing groups included in the sensing group set. That is, the device operating as a responder can be associated with at least one of the multiple sensing groups. Here, the device can be a base station or a UE. For example, the sensing group set can include N sensing groups 901, 902, 903, and 904, and responder B can belong to sensing group 1 901, sensing group 2 902, and sensing group 3 903 among the N sensing groups. As an example, sensing group 1 901 can include responder A and responder B, and sensing group 2 902 can include responder B, responder C, and responder D. Additionally, sensing group 3 903 can include responder B and responder E, and sensing group N 904 can include responder F and responder G. This configuration of sensing groups is merely an example for ease of understanding, and this disclosure is not limited thereto.
[0184] Figure 10 Another example of a sensor group set according to one embodiment of the present disclosure is illustrated. (See also...) Figure 11A responder may belong to only one of the multiple sensing groups included in the sensing group set. That is, a responder may be included in different sensing groups in a non-overlapping manner. In other words, when a first device operating as a responder belongs to one sensing group, that first device may not belong to another sensing group. Here, the first device may be a base station or a UE. For example, the sensing group set may include N sensing groups 1001, 1002, and 1003, and responders A and B may belong to only sensing group A1001. As an example, sensing group 1 1001 may include responders A and B, and sensing group 2 1002 may include responders C and D. Additionally, sensing group N 1003 may include responders E, F, and G. This configuration of sensing groups is merely an example for ease of understanding, and this disclosure is not limited thereto.
[0185] Figure 11 Another example of a sensor group set according to one embodiment of the present disclosure is illustrated. (See also...) Figure 12 The initiator and / or responder may belong to at least one of multiple sensing groups included in the sensing group set. For example, the sensing group set may include N sensing groups 1101, 1102, 1103, 1104, and 1105, and initiator B and responder B may belong to all of sensing group 1 1101, sensing group 2 1102, and sensing group 3 1103. As an example, sensing group 1 1101 may include initiator A, initiator B, responder A, and responder B, and sensing group 2 1102 may include initiator B, responder B, responder C, and responder D. Additionally, sensing group 3 1103 may include initiator B, responder B, and responder E, sensing group 4 1104 may include responder H and responder I, and sensing group N 1105 may include initiator C, responder F, and responder G. This configuration of sensing groups is merely an example for ease of understanding, and this disclosure is not limited thereto.
[0186] Figure 12 Another example of a sensor group set according to one embodiment of the present disclosure is illustrated. (See also...) Figures 9-12An initiator and / or responder may belong to only one of the multiple sensor groups included in the sensor group set. An initiator or a responder may not be included in different sensor groups in an overlapping manner. As an example, the sensor group set may include N sensor groups 1201, 1202, and 1203, and initiator A and responder B may belong only to sensor group 1201. As an example, sensor group 1 1201 may include initiator A, responder A, and responder B, and sensor group 2 1202 may include initiator C, initiator G, responder C, and responder D. Additionally, sensor group N 1203 may include initiator B, responder E, responder F, and responder G. This configuration of sensor groups is merely an example for ease of understanding, and this disclosure is not limited thereto.
[0187] For reference Figure 9 As described, network nodes for sensing systems and / or sensing services are pre-configured with a set of sensing groups, and each device (e.g., a base station or UE) with functionality supporting the sensing measurement process can know at least one sensing group to which it belongs. Each device can identify the sensing group to which it belongs by obtaining information about at least one sensing group (e.g., a sensing group index) from the network nodes. For example, as Figure 13 As shown, responder B can know that it belongs to sensing group 1, sensing group 2, and sensing group 3. Additionally, the initiator can identify the size of each sensing group, the responder's capabilities, and / or exposure information within each sensing group. Exposure information may include information about exposure scenarios differentiated by the amount and / or type of exposure information. When the above information is provided from each sensing group, the initiator can select at least one sensing group from among the at least one sensing groups to which it belongs to perform the sensing measurement process based on the provided information.
[0188] In this disclosure, information about the sensing groups of the UE and / or base station can be exposed to the sensing initiator. In this case, the information about the exposed sensing groups can vary depending on exposure scenario 1 or exposure scenario 2. Furthermore, the members of each sensing group (e.g., the responder) can vary based on the exposure information.
[0189] According to exposure scenario #1, the existence of a sensing group can be exposed by exposing the index of each sensing group within the set of sensing groups. How the sensing system and / or sensing service arranges the members of each sensing group (e.g., the responders) can vary depending on the implementation. When selecting a sensing group, the initiator may have only limited information (e.g., the size of each sensing group) and may not have any additional information.
[0190] In contrast, according to exposure scenario #2, additional information about each sensing group can be exposed. For example, according to exposure scenario #2, the exposed information may include information such as the number of members in the sensing group, geographic location / area information covered by the sensing group, target sensing service area information, mobile target sensing service area information, and / or member information (e.g., subscriber information). According to exposure scenario #2 as described above, exposing additional information about each sensing group can help the initiator select one or more sensing groups from the set of sensing groups.
[0191] To configure a sensing group based on exposure information, the following procedure can be performed.
[0192] 1. Network nodes and / or base stations assess the intent / preferences of each sensing group near the sensing initiator, which will be associated with the sensing initiator. Intent / preferences can be assessed based on exposure information.
[0193] 2. Network nodes and / or base stations send intent / preference information for each sensing group to the sensing initiator.
[0194] 3. The sensing initiator selects at least one sensing group from the set of sensing groups based on intent / preference information.
[0195] When a sensing group is selected, the target sensing service area information and / or the mobile target sensing service area information can serve as important information. However, the target sensing service area information and / or the mobile target sensing service area information do not necessarily have to be set as exposed information. Therefore, measures need to be prepared for this situation. For example, when configuring a set of sensing groups, at least one of the target sensing service area information or the mobile target sensing service area information for each sensing group may need to be configured as exposed information.
[0196] Considering the sensing measurement process, a minimum number of responders can be configured to satisfy specific conditions during the sensing measurement process. This minimum number of responders can be referred to as a first threshold. At least one sensing group (e.g., a set of sensing groups) can exist, predefined, configured, or indicated for a specific initiator or responder. This disclosure proposes several options for the sensing group selection process and corresponding signaling.
[0197] Figure 13 An example of a sensor group set according to one embodiment of the present disclosure is illustrated. Specifically, Figure 13 Examples of sensor set 1301 from the perspective of the initiator and sensor set 1303 from the perspective of the responder B are shown. Referencing is optional. Figure 13 At least one of the steps described, or the order of at least one step may be changed.
[0198] Reference Figure 13Each of the multiple sensing groups included in the sensing group set can be configured to include at least one responder. In this case, at least one responder can belong to at least one sensing group. In contrast, the initiator does not belong to any of the multiple sensing groups included in the sensing group set. In this case, the initiator can select any sensing group within the sensing group set. However, since exposure information for the entire sensing group set must be provided to the initiator, relatively large resources are required. Alternatively, depending on the sensing system, specific sensing groups can be provided or exposed only to the initiator, allowing the initiator to efficiently select the optimal sensing group based on a limited number of potential sensing groups and corresponding exposure information. From the responder's perspective, responder B belongs to sensing group 1, sensing group 2, and sensing group 3, and can provide exposure information for each sensing group. Alternatively, as a responder, only the sensing group ID number can be provided without providing exposure information.
[0199] Step 1: As Figure 14 The configuration shows a set of sensor groups, and an index is assigned to each sensor group.
[0200] Step 2: The initiator performs an authentication process to select at least one sensing group.
[0201] Step 3: The initiator selects at least one sensing group from the set of sensing groups based on exposure information at various levels, and instructs potential responders within the selected sensing group to be aware of the start of the sensing measurement process.
[0202] - The initiator can select one or more sensing groups with a size equal to or greater than the first threshold.
[0203] - When the initiator determines that the number of responders who have reported sensing measurement data during the sensing measurement process is less than a first threshold, the initiator may terminate the corresponding sensing group.
[0204] Step 4: When at least one of the target sensing service area information or the mobile target sensing service area information is not present in the exposure information, the target sensing service area information and / or the mobile target sensing service area information is generated as exposure information when configuring the sensing group set.
[0205] When a new initiator intends to participate in the sensing measurement process, it needs information about the configured set of sense groups. The new initiator can wait to receive the corresponding information, which is configured periodically. Alternatively, the new initiator can send a request for information that triggers the generation of the information to be configured.
[0206] When a new responder intends to participate in the sensing measurement process, the new responder needs to belong to a new set of sensing groups. The new responder can send requests to participate in one or more sensing groups within the new set of sensing groups. When a new set of sensing groups is configured, the new responder can be included as a member in one or more sensing groups with one or more indices.
[0207] Figure 14 Another example of a sensor group set according to one embodiment of the present disclosure is illustrated. Specifically, Figure 14 Examples of sensor group set 1401 from the perspective of the initiator and sensor group set 1403 from the perspective of the responder B are shown. Referencing is optional. Figure 14 At least one of the steps described, or the order of at least one step may be changed.
[0208] Reference Figure 14 Each of the multiple sensor groups in the sensor group set is configured to include at least one responder. In this case, each responder may belong to only one sensor group. In contrast, the initiator does not belong to any of the multiple sensor groups in the sensor group set. In this case, the initiator can select any sensor group from the multiple sensor groups in the sensor group set. However, since exposure information for the entire sensor group set needs to be provided to the initiator, relatively large resources are required. Alternatively, depending on the sensing system, specific sensor groups may be provided or exposed only to the initiator, allowing the initiator to efficiently select the optimal sensor group based on a limited number of potential sensor groups and corresponding exposure information. From the responder's perspective, responder B may belong to only one sensor group in the sensor group set (e.g., sensor group 1) and may provide exposure information for the corresponding sensor group. Alternatively, the responder may only need the sensor group ID number without needing exposure information.
[0209] Step 1: As Figure 15 The configuration shows a set of sensor groups, and an index is assigned to each sensor group.
[0210] Step 2: The initiator performs the authentication process to select a sensing group.
[0211] Step 3: The initiator selects a sensing group from the set of sensing groups based on exposure information at various levels, and instructs potential responders within the selected sensing group to be aware of the start of the sensing measurement process.
[0212] - The initiator can select a sensing group with a size equal to or greater than the first threshold.
[0213] - When the initiator determines that the number of responders who have reported sensing measurement data during the sensing measurement process is less than a first threshold, the initiator may terminate the corresponding sensing group.
[0214] Step 4: When at least one of the target sensing service area information or the mobile target sensing service area information is not present in the exposure information, the target sensing service area information and / or the mobile target sensing service area information is generated as exposure information when configuring the sensing group set.
[0215] When a new initiator intends to participate in the sensing measurement process, it needs information about the configured set of sense groups. The new initiator can wait to receive the corresponding information, which is configured periodically. Alternatively, the new initiator can send a request for information that triggers an event to configure this information.
[0216] When a new responder intends to participate in the sensing measurement process, the new responder needs to belong to a new sensing group set. The new responder can send a request to participate in a sensing group within the new sensing group set. When configuring a new sensing group set, the new responder can be included as a member in a sensing group with one or more indices.
[0217] Figure 15 Another example of a sensor group set according to one embodiment of the present disclosure is illustrated. Specifically, Figure 13 The example illustrates sensor set 1501 from the perspective of initiator B and sensor set 1503 from the perspective of responder B. Referencing is optional. Figure 15 At least one of the steps described, or the order of at least one step may be changed.
[0218] Reference Figure 15 Each of the multiple sensing groups in the sensing group set can be configured to include at least one initiator and at least one responder. In this case, at least one initiator and / or at least one responder can belong to at least one sensing group. Therefore, an initiator can belong to at least one of the multiple sensing groups within the sensing group set. When a limited number of sensing groups are given to each initiator, the initiator can efficiently select the optimal sensing group based on a limited number of potential sensing groups and corresponding exposure information. For example, since initiator B belongs to sensing groups 1, 2, and 3, initiator B can select at least one sensing group from sensing groups 1, 2, and 3. From the responder's perspective, the responder belongs to at least one sensing group within the sensing group set. For example, responder B belongs to sensing groups 1, 2, and 3, and exposure information for each group can be exposed. Alternatively, as a responder, only the sensing group ID number may be needed in the absence of exposure information.
[0219] Step 1: As Figure 16 The configuration shows a set of sensor groups, and an index is assigned to each sensor group.
[0220] Step 2: The initiator performs an authentication process to select at least one sensing group from among the sensing groups that include the sensing initiator.
[0221] Step 3: The initiator selects one or more sensing groups from the set of sensing groups including the initiator based on the exposure information at various levels.
[0222] Step 4: When at least one of the target sensing service area information or the mobile target sensing service area information is not present in the exposure information, the target sensing service area information and / or the mobile target sensing service area information is generated as exposure information when the sensing group set is configured.
[0223] Step 5: The initiator instructs potential responders within the selected sensing group to be aware of the start of the sensing measurement process.
[0224] - The initiator can select one or more sensing groups with a size equal to or greater than the first threshold.
[0225] - When the initiator determines that the number of responders who have reported sensing measurement data during the sensing measurement process is less than a first threshold, the initiator may terminate the corresponding sensing group.
[0226] When a new initiator intends to participate in the sensing measurement process, it needs information about the configured set of sensing groups. The new initiator can send a request to participate in one or more sensing groups within the new set. When configuring a new set of sensing groups, the new initiator can be included as a member in one or more sensing groups with one or more indices.
[0227] When a new responder intends to participate in the sensing measurement process, the new responder needs to belong to a new set of sensing groups. The new responder can send requests to participate in one or more sensing groups within the new set of sensing groups. When a new set of sensing groups is configured, the new responder can be included as a member in one or more sensing groups with one or more indices.
[0228] Figure 16 Another example of a sensor group set according to one embodiment of the present disclosure is illustrated. Specifically, Figure 16 The example illustrates sensor set 1601 from the perspective of initiator A and sensor set 1603 from the perspective of responder B. Referencing is optional. Figure 16 At least one of the steps described, or the order of at least one step may be changed.
[0229] ReferenceFigure 16 Each of the multiple sensor groups in the sensor group set can be configured to include at least one initiator and at least one responder. In this case, the initiator and / or responder can belong to only one sensor group. Therefore, the initiator can belong to only one sensor group in the sensor group set. When each initiator provides only one sensor group, the initiator can effectively select the optimal sensor group. When exposure information for a sensor group exists, the optimal sensor group can be selected based on the exposure information. From the responder's perspective, the responder belongs to only one sensor group in the sensor group set. For example, responder B belongs to only sensor group 1 and can expose exposure information for sensor group 1. Alternatively, as a responder, only the sensor group ID number may be required in the absence of exposure information.
[0230] Step 1: As Figure 17 The configuration shows a set of sensor groups, and an index is assigned to each sensor group.
[0231] Step 2: The initiator selects a sensing group that includes itself based on various levels of exposure information. (No further information provided.)
[0232] Step 3: When at least one of the target sensing service area information or the mobile target sensing service area information is in the exposure information, the target sensing service area information and / or the mobile target sensing service area information is generated as exposure information when configuring the sensing group set.
[0233] Step 4: The initiator instructs potential responders within the selected sensing group to be aware of the start of the sensing measurement process.
[0234] - The initiator can select one or more sensing groups with a size equal to or greater than the first threshold.
[0235] - When the initiator determines that the number of responders who have reported sensing measurement data during the sensing measurement process is less than a first threshold, the initiator may terminate the corresponding sensing group.
[0236] When a new initiator intends to participate in the sensing measurement process, it needs information about the configured set of sensing groups. The new initiator can send a request to participate in one or more sensing groups within the new set. When configuring a new set of sensing groups, the new initiator can be included as a member in one or more sensing groups with one or more indices.
[0237] When a new responder intends to participate in the sensing measurement process, the new responder needs to belong to a new sensing group set. The new responder can send requests to participate in one or more sensing groups within the new sensing group set. When configuring a new sensing group set, the new responder can be included as a member in one or more sensing groups with one or more indices.
[0238] Figure 17 An example of an information receiving process for sensing measurements according to one embodiment of the present disclosure is illustrated. Figure 17 An example of a method performed by a first device is illustrated. The first device may be a UE (User Equipment).
[0239] Reference Figure 18 In step S1701, the first device receives a capability information request. This device can receive a message from the second device requesting the transmission of UE capability information. The second device can be a base station or a network node.
[0240] In step S1703, the first device sends 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 first device supports the sensing service, computing capability information of the first device, or the type of raw data that can be processed by the first device.
[0241] In step S1705, the first device receives control information or configuration information. That is, the first device can receive control information or configuration information for the sensing service from the second device. The control information or configuration information for the sensing service may include sensing-related information for at least one of a plurality of pre-configured sensing groups. For example, the control information or configuration information may include only sensing-related information for at least one sensing group to which the first device belongs, or it may include sensing-related information for all sensing groups in the plurality of sensing groups. The sensing-related information may include at least one of the identification information (e.g., index or ID) or exposure information of the sensing group. In this case, the exposure information can be configured differently depending on the exposure scenario.
[0242] In step S1707, the first device configures the sensing group based on control information or configuration information. That is, the first device can select at least one sensing group for performing the sensing measurement process based on control information or configuration information, and can utilize at least one other device included in the selected at least one sensing group to perform the sensing function. The first device can perform the sensing measurement process with at least one member within the selected at least one sensing group by sending information indicating the start of the sensing measurement process to at least one member (e.g., a potential responder) within the selected at least one sensing group.
[0243] Figure 18 An example of an information transmission process for sensing measurements according to one embodiment of the present disclosure is illustrated. Figure 18 The method performed by a second device is illustrated. The second device may be a network node or a base station.
[0244] Reference Figures 9-12 In step S1801, the second device sends a capability information request. This device can send a message to the first device requesting the transmission of capability information.
[0245] In step S1803, the second device receives capability information. That is, the second device receives capability information from the first device. The capability information may include capability information related to the sensing service. For example, the capability information related to the sensing service may include at least one of information indicating whether the first device supports the sensing service, computing capability information of the first device, or the type of raw data that can be processed by the first device.
[0246] In step S1805, the second device generates control information or configuration information based on the capability information. That is, the second device can generate control information or configuration information for the sensing service based on the capability information of the first device. Based on the capability information of the first device, the second device can, as referred to... Figure 19 The sensor group set is configured as described, and control information or configuration information including information about the configured sensor group set can be generated. Information about the sensor group set may include at least one of the following: identification information of the sensor group to which the device belongs (e.g., index or sensor group ID), exposure information of the sensor group to which the device belongs, exposure information of each of the multiple sensor groups included in the sensor group set, minimum number of responders for the sensing service, duration of reconfiguration for the sensor group set, or reconfiguration conditions for the sensor group set. The exposure information of the sensor group may include at least one of the following: index of the sensor group, number of members of the sensor group, geographic location information covered by the sensor group, geographic area information covered by the sensor group, target sensing service area information of the sensor group, mobile target sensing service area information of the sensor group, or member information included in the sensor group. The exposure information can be configured differently depending on the exposure scenario.
[0247] In step S1807, the second device sends control information or configuration information. The second device can send the control information or configuration information to the first device. RRC parameters, DCI, or MAC CE can be used to send the control information or configuration information.
[0248] Figure 19 An example of a sensor group configuration process according to one embodiment of the present disclosure is illustrated. Figure 19 The method performed by the first device is illustrated. Figure 17At least some of the operations can be understood as Figure 19 Detailed operation of steps S1705 and S1707.
[0249] Reference Figures 13-16 In step S1901, the first device obtains information about a set of sensing groups. The first device may obtain this information based on control information or configuration information received from the second device. The information about the set of sensing groups may include sensing-related information for at least one of a plurality of pre-configured sensing groups. For example, the information about the set of sensing groups may include only sensing-related information for at least one sensing group to which the first device belongs, or it may include sensing-related information for all sensing groups in a plurality of sensing groups. The sensing-related information may include at least one of the following: identification information (e.g., index or ID) or exposure information of the sensing group. In this case, depending on the exposure scenario, the exposure information may include at least one of the following: index, number of members, covered geographic location information, covered geographic area information, target sensing service area information, mobile target sensing service area information, or member information. According to one embodiment, the control information or configuration information may also include at least one of the following: a minimum number of responders for the sensing service, a reconfiguration duration for the set of sensing groups, or reconfiguration conditions for the set of sensing groups.
[0250] In step S1903, the first device selects a sensing group. The first device can select at least one sensing group based on information about the set of sensing groups. (See reference...) Figure 7 As described, the first device can select at least one sensing group based on the existence of a sensing group to which the first device belongs. The existence of a sensing group to which the first device belongs can be identified based on information about a set of sensing groups. When no sensing group to which the first device belongs exists, the first device can select at least one sensing group from among multiple sensing groups based on exposure information of each of the multiple sensing groups within the set of sensing groups. Conversely, when at least one sensing group to which the first device belongs exists, the first device can select at least one sensing group from among the sensing groups to which the first device belongs based on exposure information of the at least one sensing group to which the first device belongs. When selecting a sensing group, the first device can also consider specified conditions and can select at least one sensing group. For example, the first device can select at least one sensing group that satisfies a minimum number of responders.
[0251] In step S1905, the first device performs a sensing measurement process. The first device can perform the sensing measurement process with at least one member within a selected at least one sensing group by sending information indicating the start of the sensing measurement process. The information indicating the start of the sensing measurement process can be unicast or multicast to at least one member within the selected at least one sensing group. The first device can send the index or ID of the selected at least one sensing group along with the information indicating the start of the sensing measurement process. This is to allow other devices included as members of the selected at least one sensing group to recognize that the sensing measurement process for the selected sensing group has started. Thereafter, the first device and other devices included as at least one member of the selected at least one sensing group can perform reference... Figure 8 and / or The description includes a sensing measurement configuration setup phase, a sensing measurement data generation and reporting phase, a sensing measurement configuration termination phase, and a sensing group termination phase. Here, when the number of responders reporting sensing measurement data is less than the minimum number of responders, the first device can terminate the corresponding sensing group.
