Description

Technical Field

[0001] The present disclosure relates to the technical field of wireless communications, and more particularly, to a user equipment, a device and a method executed by the same in a wireless communication system. Background Art

[0002] Considering the development of wireless communication from generation to generation, these technologies are mainly developed for services targeting people, such as voice calls, multimedia services, and data services. With the commercialization of the fifth-generation (5G) communication system, the number of connected devices is expected to grow exponentially. These will be increasingly connected to the communication network. Examples of the Internet of Things can include vehicles, robots, drones, home appliances, displays, smart sensors connected to various infrastructures, construction machinery, and factory equipment. Mobile devices are expected to develop in various forms such as augmented reality glasses, virtual reality headsets, and holographic devices. Efforts have been made to develop improved 6G communication systems in order to provide various services by connecting hundreds of billions of devices and things in the sixth-generation (6G) era. For these reasons, 6G communication systems are called super 5G systems.

[0003] The 6G communication system, which is expected to be commercialized around 2030, will have a peak data rate of tera (1,000 gigabits) bps and a radio latency of less than 100 μsec, thus being 50 times the data rate of the 5G communication system and having 1 / 10 of its radio latency.

[0004] In order to achieve such high data rates and ultra-low latency, the implementation of 6G communication systems in terahertz (e.g., 95GHz to 3THz bands) has been considered. It is expected that since the path loss and atmospheric absorption in the terahertz band are more serious than those in the millimeter wave (mmWave) band introduced in 5G, the technology that can ensure the signal transmission distance (i.e., coverage) will become more critical. As the main technology to ensure coverage, it is necessary to develop radio frequency (RF) elements, antennas, new waveforms with better coverage than orthogonal frequency division multiplexing (OFDM), beamforming and massive multiple input multiple output (MIMO), full dimensional multiple input multiple output (FD-MIMO), array antennas, and multi-antenna transmission technologies such as massive antennas. In addition, new technologies have been discussed to improve signal coverage in the terahertz band, such as metamaterial-based lenses and antennas, orbital angular momentum (OAM), and reconfigurable intelligence surface (RIS).

[0005] In addition, in order to improve spectrum efficiency and overall network performance, the following technologies have been developed for 6G communication systems: full-duplex technology for enabling uplink and downlink transmissions to use the same frequency resources simultaneously; network technology that utilizes satellites, high-altitude platform stations (HAPS), etc. in an integrated manner; improved network structure to support mobile base stations, etc., and to enable network operation optimization and automation, etc.; dynamic spectrum sharing technology with conflict avoidance based on spectrum usage prediction: using artificial intelligence (AI) in wireless communications to improve overall network operations by utilizing AI from the design stage of developing 6G and internalizing end-to-end AI support functions; and next-generation distributed computing technology that overcomes the computing power limitations of user equipment (UE) through ultra-high performance communication and computing resources achievable on the network (such as mobile edge computing (MEC), cloud, etc.). In addition, attempts are continuing to strengthen connectivity between devices, optimize networks, promote software-based network entities, and increase openness of wireless communications by designing new protocols to be used in 6G communication systems, developing mechanisms for implementing hardware-based security environments and secure use of data, and developing technologies for maintaining privacy.

[0006] It is expected that the research and development of 6G communication systems including hyperconnectivity of person to machine (P2M) and machine to machine (M2M) will bring about the next hyperconnectivity experience. In particular, services such as truly immersive extended reality (XR), high-fidelity mobile holograms, and digital replicas are expected to be provided through 6G communication systems. In addition, services such as remote surgery, industrial automation, and emergency response for enhanced safety and reliability will be provided through 6G communication systems, making the technology applicable to various fields such as industry, healthcare, automobiles, and home appliances.

In addition, those skilled in the art will appreciate that the principles of the present disclosure can be implemented in any appropriately arranged wireless communication system.

[0059] The following Figures 1 to 3 Various embodiments of the present disclosure are described as being implemented in a wireless communication system. Figures 1 to 3 The description is not meant to imply physical or architectural limitations to the manner in which different embodiments may be implemented. Different embodiments of the present disclosure may be implemented in any suitably arranged communications system.

[0060] Figure 1 An example wireless network according to an embodiment of the present disclosure is shown. Figure 1 The embodiment of the wireless network shown in FIG. 1 is for illustration only. Other embodiments of the wireless network 100 may be used without departing from the scope of the present disclosure.

[0061] like Figure 1As shown, the wireless network includes a base station (next generation nodeB, gNB or gNodeB) 101, gNB 102, and gNB 103. gNB 101 communicates with gNB 102 and gNB 103. gNB 101 also communicates with at least one network 130 such as the Internet, a proprietary Internet Protocol (IP) network, or other data network.

[0062] The gNB 102 provides wireless broadband access to a network 130 for a plurality of first user equipments (UEs) within a coverage area 120 of the gNB 102. The plurality of first UEs include a UE 111 that may be located at a small business (SB); a UE 112 that may be located at an enterprise (E); a UE 113 that may be located at a WiFi hot spot (HS); a UE 114 that may be located at a first residence (R1); a UE 115 that may be located at a second residence (R2); and a UE 116 that may be a mobile device (M) such as a cellular phone, a wireless laptop, a wireless personal digital assistant (PDA), etc. The gNB 103 provides wireless broadband access to the network 130 for a plurality of second UEs within a coverage area 125 of the gNB 103. The plurality of second UEs include UE 115 and UE 116 and subscriber stations (SS, e.g., UEs) 117, 118, and 119. In some embodiments, one or more of gNBs 101-103 may communicate with each other and UEs 111-116 using existing wireless communication technologies, and one or more of UEs 111-119 may communicate directly with each other (e.g., UEs 117-119) using other existing or proposed wireless communication technologies.

[0063] Depending on the type of network, the term "base station" or "BS" may refer to any component (or collection of components) configured to provide wireless access to a network, such as a transmit point (TP), a transmit-receive point (TRP), an enhanced (or "evolved") base station (eNodeB or eNB), a 5G base station (gNB), a macro cell, a femto cell, a wireless fidelity (WiFi) access point (AP), or other wireless capable devices. A base station may provide wireless access according to one or more wireless communication protocols, such as 3GPP 5G new radio (NR), Long Term Evolution (LTE), LTE-Advanced (LTE-A), high speed packet access (HSPA), Wi-Fi 802.11a / b / g / n / ac, etc. For convenience, various names of base station type devices and functions are used interchangeably in this patent document to refer to network infrastructure components that provide wireless access to remote terminals. Also, depending on the network type, the term "user equipment" (UE) may refer to any component such as a mobile station (MS), a subscriber station (SS), a remote terminal, a wireless terminal, a reception point, or a user device, etc. For convenience, various names of user equipment type devices and functions are used interchangeably in this patent document to refer to a remote wireless device that wirelessly accesses a BS regardless of whether the UE is a mobile device (such as a mobile phone or a smart phone) or a remote wireless device that is generally considered to be a fixed device (such as a desktop computer or a vending machine).

[0064] Dashed lines illustrate the approximate extents of coverage areas 120 and 125, which are shown as generally circular for purposes of illustration and explanation only. It should be clearly understood that coverage areas associated with a gNB, such as coverage areas 120 and 125, may have other shapes, including irregular shapes, depending on the configuration of the gNB and variations in the wireless environment associated with natural and artificial obstacles.

[0065] As described in more detail below, one or more of UEs 111-119 include circuitry, programming, or a combination thereof. In certain embodiments, one or more of gNBs 101-103 include circuitry, programming, or a combination thereof.

[0066] although Figure 1 An example of a wireless network is shown, but Figure 1Various changes may be made. For example, wireless network 100 may include any number of gNBs and any number of UEs in any suitable arrangement. Moreover, gNB 101 may communicate directly with any number of UEs and provide those UEs with wireless broadband access to network 130. Similarly, each gNB 102-103 may communicate directly with network 130 and provide UEs with direct wireless broadband access to network 130. In addition, gNBs 101, 102, and / or 103 may provide access to other or additional external networks such as an external telephone network or other types of data networks.

[0067] Figure 2 An example base station according to an embodiment of the present disclosure is shown. Figure 2 The embodiment of the gNB 102 shown in FIG. is for illustration only, and Figure 1 gNBs 101 and 103 may have the same or similar configurations. However, gNBs appear in a variety of configurations, and Figure 2 The scope of the present disclosure is not limited to any particular implementation of the gNB.

[0068] like Figure 2 As shown in FIG. 1 , gNB 102 includes multiple antennas 200a-200n, multiple radio frequency (RF) transceivers 201a-201n, a transmit (TX) processing circuit 203, and a receive (RX) processing circuit 204. gNB 102 also includes a controller / processor 205, a memory 206, and a backhaul or network interface (IF) 207.

[0069] The RF transceivers 201a-201n receive incoming RF signals from the antennas 200a-200n, such as signals sent by UEs in the network 100. The RF transceivers 201a-201n down-convert the incoming RF signals to generate intermediate frequency (IF) or baseband signals. The IF or baseband signals are sent to the RX processing circuit 204, which generates processed baseband signals by filtering, decoding and / or digitizing the baseband or IF signals. The RX processing circuit 204 sends the processed baseband signals to the controller / processor 205 for further processing.

[0070] TX processing circuit 203 receives analog or digital data (such as voice data, web data, email, or interactive video game data) from controller / processor 205. TX processing circuit 203 encodes, multiplexes, and / or digitizes the outgoing baseband data to generate processed baseband or IF signals. RF transceivers 201a-201n receive the outgoing processed baseband or IF signals from TX processing circuit 203 and up-convert the baseband or IF signals to RF signals that are transmitted via antennas 201a-201n.

[0071] Controller / processor 205 may include one or more processors or other processing devices that control the overall operation of gNB 102. For example, controller / processor 205 may control the reception of forward channel signals and the transmission of reverse channel signals by RF transceivers 201a-201n, RX processing circuitry 204, and TX processing circuitry 203 in accordance with well-known principles. Controller / processor 205 may also support additional functionality, such as more advanced wireless communication functionality.

[0072] For example, the controller / processor 205 may support beamforming or directional routing operations in which outgoing signals from multiple antennas 200a-200n are weighted differently to effectively steer the outgoing signals in a desired direction. Any of a variety of other functions may be supported in the gNB 102 by the controller / processor 205.

[0073] The controller / processor 205 is also capable of executing programs and other processes, such as an operating system (OS), located in the memory 206. The controller / processor 205 can move data into or out of the memory 206 as required by the executing process.

[0074] The controller / processor 205 is also connected to a backhaul or network interface 207. The backhaul or network interface 207 allows the gNB 102 to communicate with other devices or systems via a backhaul connection or via a network. The interface 207 may support communication over any appropriate (one or more) wired or wireless connections. For example, when the gNB 102 is implemented as part of a cellular communication system (such as a cellular communication system supporting 5G, LTE, or LTE-A), the interface 207 may allow the gNB 102 to communicate with other gNBs via a wired or wireless backhaul connection. When the gNB 102 is implemented as an access point, the interface 207 may allow the gNB 102 to communicate over a wired or wireless local area network or over a wired or wireless connection to a larger network (such as the Internet). The interface 207 includes any appropriate structure that supports communication over a wired or wireless connection such as an Ethernet or RF transceiver.

For example, Figure 2 The various components in may be combined, further subdivided, or omitted, and additional components may be added according to specific needs.

[0077] Figure 3 An example user device according to an embodiment of the present disclosure is shown. Figure 3 The embodiment of UE 116 shown in FIG. 1 is for illustration only, and Figure 1 UEs 111-115 and 117-119 may have the same or similar configurations. However, UEs may appear in a variety of configurations, and Figure 3 The scope of the present disclosure is not limited to any particular implementation of the UE.

[0078] like Figure 3 As shown in FIG. 1 , UE 116 includes an antenna 301, a radio frequency (RF) transceiver 302, a TX processing circuit 303, a microphone 304, and a receive (RX) processing circuit 305.

The memory 311 includes an OS 312 and one or more applications 313.

[0079] RF transceiver 302 receives incoming RF signals transmitted by a gNB of network 100 from antenna 301. RF transceiver 302 downconverts the incoming RF signals to generate an IF or baseband signal. The IF or baseband signal is sent to RX processing circuitry 305, which generates a processed baseband signal by filtering, decoding, and / or digitizing the baseband or IF signal. RX processing circuitry 305 sends the processed baseband signal to speaker 306 (such as for voice data) or processor 307 for further processing (such as for web browsing data).

[0080] The TX processing circuit 303 receives analog or digital voice data from the microphone 304 or other outgoing baseband data (such as web data, email, or interactive video game data) from the processor 307. The TX processing circuit 303 encodes, multiplexes, and / or digitizes the outgoing baseband data to generate a processed baseband or IF signal. The RF transceiver 302 receives the outgoing processed baseband or IF signal from the TX processing circuit 303 and up-converts the baseband or IF signal to an RF signal that is transmitted via the antenna 301.

[0081] The processor 307 may include one or more processors or other processing devices and executes the OS 312 stored in the memory 311 to control the overall operation of the UE 116. For example, the processor 307 may control the reception of forward channel signals and the transmission of reverse channel signals by the RF transceiver 302, the RX processing circuit 305, and the TX processing circuit 303 according to well-known principles. In some embodiments, the processor 307 includes at least one microprocessor or microcontroller.

[0082] The processor 307 is also capable of executing other processes and programs located in the memory 311, such as a process for CSI (Channel State Information) reporting on the uplink channel. The processor 307 can move data into or out of the memory 311 as needed to execute the process. In some embodiments, the processor 307 is configured to execute the application 313 based on the OS 312 or in response to a signal received from the gNB or operator. The processor 307 is also coupled to the I / O interface 308, which provides the UE 116 with the ability to connect to other devices such as laptops and portable computers. The I / O interface 308 is the communication path between these accessories and the processor 307.

[0083] Processor 307 is also connected to touch screen display 310. A user of UE 116 may use touch screen display 310 to enter data into UE 116. Touch screen display 310 may be a liquid crystal display, light emitting diode display, or other display capable of rendering text and / or at least limited graphics, such as from a website.

[0085] although Figure 3 An example of UE 116 is shown, but the Figure 3 Make various changes. For example, Figure 3 The various components in the embodiment may be combined, further subdivided, or omitted, and additional components may be added as required. As a specific example, processor 307 may be divided into multiple processors, such as one or more central processing units (CPUs) and one or more graphics processing units (GPUs). Furthermore, although Figure 3 The UE 116 is shown configured as a mobile phone or smart phone, but the UE may be configured to operate as other types of mobile or stationary devices.

[0086] The text and drawings are provided as examples only to help understand the present disclosure. They should not be interpreted as limiting the scope of the present disclosure in any way. Although certain embodiments and examples have been provided, it will be apparent to those skilled in the art based on what is disclosed herein that the embodiments and examples shown may be changed without departing from the scope of the present disclosure.

[0087] With the advancement of science and technology, the types of communication equipment are becoming more and more diverse. In addition to traditional mobile phones, computers and other devices, they can also include mobile robots, such as self-driving vehicles, drones, etc. This type of mobile device often needs to have the ability to accurately locate or be accurately located, so as to accurately identify the current situation and respond, that is, to have positioning capabilities similar to those provided by radar technology. A direct way may be to equip the communication equipment with a radar module. However, as the working frequency band of the communication system has gradually developed to a higher frequency band in recent years, the communication frequency band has gradually approached the radar frequency band. The resulting interference and resource conflicts between the communication system and the radar system will be inevitable. One idea to solve this problem may be to consider the fusion system of communication and radar, called communication perception integration technology, to further enhance the function of the communication system and improve the spectrum efficiency. At present, both the industry and academia regard communication perception integration as one of the key technologies for future communication systems.

[0088] The core concept of communication and perception integration is to use the same set of hardware equipment to achieve the perception function of the surrounding environment at the cost of as little resource overhead as possible while ensuring basic communication functions. That is, the communication nodes in the communication system (for example, gNB, UE, repeater, backhaul access integrated base station IAB, etc.) can have the functions of communication and perception at the same time, which can be called communication and perception integrated nodes, hereinafter referred to as synaesthesia nodes. To add the perception function to the communication system, a feasible solution is that the first synaesthesia node receives the signal for perception (hereinafter referred to as the perception signal) sent by the second synaesthesia node, and obtains the characteristics of the perceived target object based on the signal detection of the perception signal. Since the perception signal will cause the corresponding change in the propagation channel frequency response after being reflected by the perception target object in the environment, and the change in frequency response has a corresponding relationship with the characteristics of the distance, moving speed, etc. of the perception target object, the first synaesthesia node can estimate the propagation channel based on the received perception signal, thereby obtaining the characteristics of the perception target object. Among them, the characteristics of the perceived target object may include but are not limited to the number of perceived target objects, the distance between the perceived target object and the sensing node, the radial velocity of the perceived target object, etc.; and the perceived target object may be an object connected to a communication network (for example, a base station, a terminal, etc.), or an object not connected to a communication network (for example, a small drone, a building, an animal, a plant, etc.).

[0089] In the above-mentioned synaesthesia scheme, the first synaesthesia node and the second synaesthesia node can be a base station and a user respectively, for example, the first synaesthesia node is a user device and the second synaesthesia node is its serving cell; or the second synaesthesia node is a user device and the first synaesthesia node is its serving cell. According to the perception requirements, the serving cell can configure the user device to send or receive a perception signal. At this time, corresponding to the user device being configured to send an uplink perception signal, the base station of the serving cell receives the uplink perception signal and performs a perception measurement, hereinafter referred to as uplink perception; corresponding to the user device being configured to receive a downlink perception signal, the user device receives the downlink perception signal and performs a perception measurement, hereinafter referred to as downlink perception.

[0090] It is worth noting that in some scenarios with high requirements for perception accuracy, such as autonomous driving, base stations or user devices often need to accumulate multiple perception signals and improve perception accuracy through signal merging or diversity. To achieve this goal, according to existing protocols, the service cell can configure a single user device to send (or receive) repeated physical signals, and the base station (or user device) of the service cell receives and merges multiple repetitions of the same physical signal to improve perception accuracy. However, this method will significantly increase the physical resource overhead used for perception by each user device and reduce the communication rate of a single user device. How to reduce the physical resource overhead of perception in this scenario and reduce the impact on the communication rate is an urgent problem to be solved.

[0091] In fact, the serving cell base station can receive uplink perception signals from multiple user equipments, or obtain downlink perception measurement results of multiple user equipments based on downlink perception signals, so that the purpose of perception combining gain or diversity gain to improve perception accuracy can still be obtained. For example, it is still possible to obtain combining gain by combining uplink perception signals sent by multiple user equipments or combining downlink perception measurement results reported by multiple user equipments; or, by selecting several perception measurement results reported by multiple user equipments with larger reference signal receiving power for combination, combining gain and diversity gain, etc. are obtained.

[0092] In order to achieve the above effect, first of all, it should be required that the multiple user devices are at least geographically close; secondly, the uplink perception signal or downlink perception signal is required to meet certain conditions, for example, the transmission time of the uplink perception signal / downlink perception signal is the same or similar, the physical direction of the transmission beam is the same or similar, etc. Since the number of user devices configured to participate in uplink perception or downlink perception can be very large, the use of user-specific configuration methods may cause excessive signaling overhead and affect the downlink throughput of the system. How to reduce signaling overhead and ensure perception performance is an issue that needs to be considered. In addition, considering that the movement of user equipment may cause a change in position, the uplink perception signal and / or downlink perception signal configured by the user equipment according to the previous position does not correspond to the user position after the movement, and cannot be used for the diversity or merging of the perception signal or perception measurement results of the serving cell base station. Therefore, it is also necessary to support the dynamic adjustment of the perception configuration according to the change of the user position.

[0093] In the present disclosure, a perception configuration method is proposed, in which a user equipment determines whether the obtained perception configuration is effective according to a preset condition, and performs uplink perception or downlink perception according to the effective perception configuration. Among them, the perception configuration can be configured by a base station to multiple user equipments in a broadcast or multicast manner, and each user equipment determines whether the perception configuration is effective according to the preset condition. This method greatly reduces the signaling overhead of the perception configuration, and at the same time enables the user equipment to adaptively select or adjust the effective perception configuration according to its own position change, thereby ensuring that the base station obtains the merging and diversity gain of uplink perception and / or downlink perception.

[0094] The embodiment of the present disclosure provides a method for perceiving configuration, which may include the following steps: the user equipment obtains at least one perceiving configuration; the user equipment determines that one or more of the at least one perceiving configuration are effective based on at least one (preset) condition; the user equipment sends an uplink perceiving signal according to the effective perceiving configuration, or the user equipment receives a downlink perceiving signal and / or performs perceiving measurement according to the effective perceiving configuration. The uplink perceiving signal includes at least one of the following: an uplink perceiving dedicated signal, an uplink shared channel, an uplink control channel, a sounding reference signal SRS, a random access channel PRACH, an uplink positioning reference signal UL PRS, an uplink demodulation reference signal, etc.; the downlink perceiving signal includes at least one of the following: a downlink perceiving dedicated signal, a downlink shared channel, a downlink control channel, a channel state information reference signal CSI-RS, a positioning reference signal PRS, a synchronization signal, a broadcast channel PBCH, a synchronization signal / broadcast channel block SSB, a downlink demodulation reference signal, etc. The uplink (and / or downlink) perceiving dedicated signal is an uplink (and / or downlink) physical signal / channel for perceiving purposes. In this article, the perceiving configuration may be a configuration for perceiving, and may be referred to as a first configuration. A perception configuration may include one or more configuration contents or configuration parameters, etc., and may also be referred to as a perception configuration group.

[0095] In some examples of the present disclosure, the user equipment may obtain the perception configuration through at least one of high-level signaling, a media access control control unit MAC CE, and downlink control information. A specific implementation is that the user equipment obtains the perception configuration through public high-level signaling, for example, the user equipment obtains it by receiving a master information block MIB, a system information block SIB, a remaining minimum system information RMSI, and an uplink / downlink bandwidth part BWP configuration (for example, BWP-Downlink, BWP-Uplink). Another specific implementation is that the user equipment receives a broadcast / groupcast / multicast channel and obtains high-level signaling and / or MAC CE containing the perception configuration. Another specific implementation is that the user equipment receives a downlink shared channel corresponding to a specific radio network temporary identifier RNTI, and the downlink shared channel carries high-level signaling and / or MAC CE containing the perception configuration, wherein the specific RNTI is the RNTI used for the perception configuration. Another specific implementation is that the user equipment receives a downlink control channel associated with a specific RNTI (for example, scrambled by a specific RNTI), and the downlink control information carried by the downlink control channel includes the perception configuration, wherein the specific RNTI is the RNTI used for the perception configuration. Furthermore, the RNTI used for the perception configuration may be common to a user group, that is, a group of user devices are configured with the RNTI for receiving a downlink control channel for the perception configuration, and the control channel search space corresponding to the RNTI is a common search space. The above four specific implementation methods all consider the perception configuration in a public configuration manner such as broadcast or user multicast, that is, multiple user devices receive the same physical channel or physical signal sent by the base station to obtain the perception configuration signaling. Compared with the user device-specific configuration method, the public configuration method can save more resource overhead for sending configuration signaling.

[0096] In some examples of the present disclosure, each of the "at least one perception configuration" includes at least configuration information for determining a perception signal physical resource (i.e., configuration information related to the physical resource of the perception signal, for example, determining a time domain and / or frequency domain resource for sending an uplink perception signal; or determining a time domain and / or frequency domain resource for receiving a downlink perception signal and / or performing perception measurement based on the downlink perception signal) and / or information related to an effective condition of the perception configuration, etc. Further, the configuration information for determining the perception signal physical resource in the perception configuration includes at least one of the following: information related to time domain and / or frequency domain resource mapping of uplink / downlink perception signals, information related to sequences of uplink / downlink perception signals, information related to antenna ports of uplink / downlink perception signals, information related to a transmit beam of an uplink perception signal (for example, a spatial filter used by a user equipment to send a perception signal (for example, an uplink perception signal)), information related to a receive beam of a downlink perception signal (for example, a spatial filter used by a user equipment to receive a perception signal (for example, a downlink perception signal)), information related to power control, cycle and time slot offset, etc. In addition, different perception configurations may have the same configuration content, but different configuration parameter values ​​under the same configuration content. For example, the user equipment obtains N perception configurations, each of which contains relevant configuration information of the transmit beam / receive beam of the perception signal (for example, the transmit configuration indication TCI, etc.), but the specific configuration values ​​are different. Through different perception configurations, the perception signal can be configured to be sent with different transmit beams or received with different receive beams. At this time, each group of configurations can correspond to different perception needs and perceive in different expected directions. When the perception configuration contains information related to the effective condition, a specific implementation of this example is that the perception configuration contains relevant information for determining whether each perception configuration is effective. For example, the content related to the effective condition can be at least one threshold threshold for determining whether one or more perception configurations are effective, or at least one specific physical signal and / or channel index, or an effective timer for determining whether one or more perception configurations are effective. The design of including relevant information related to the effective condition in the perception configuration can enable the base station to configure the corresponding effective condition according to the perception demand / expected perception direction, ensuring that the appropriate user equipment is selected for uplink perception or downlink perception, thereby ensuring that the base station side obtains the merging and diversity gain of the perception measurement.

[0097] In some examples of the present disclosure, when the perception configuration includes relevant information of the transmission beam of the uplink perception signal, the information may be a downlink perception signal indication spatially associated with the uplink perception signal, wherein the spatial association may mean that the spatial reception (filter) parameters have a quasi-co-location relationship (e.g., a quasi-co-location relationship of type D, QCL typeD). At this time, the user equipment may determine the uplink transmission spatial filter according to the configured downlink perception signal indication (e.g., a downlink perception signal index or a resource index, etc.). A specific implementation is that the user equipment obtains a perception configuration for sending an uplink perception signal, the perception configuration includes a downlink perception signal index spatially associated with the uplink perception signal, for example, the TCI state configuration of the uplink perception signal includes a downlink perception signal index, and when the user equipment sends an uplink perception signal according to the perception configuration, the adopted uplink transmission spatial filter parameters may be obtained according to the reception spatial filter parameters of the downlink perception signal of the index received by the user equipment. And, before the user equipment obtains the downlink perception signal index configuration spatially associated with the uplink perception signal, the user equipment receives at least one downlink perception signal with a different index, wherein at least two transmission beams in the at least one downlink perception signal are different, i.e., the quasi-co-location relationship of the spatial reception (filter) parameters is not satisfied. The downlink perception signal transmitted in this way can realize downlink perception beam scanning, and one of its uses can be to provide the user equipment with a reference for determining the transmission spatial filter of the uplink perception reference signal. This design is necessary for some synaesthesia scenarios, such as aircraft perception scenarios, where the beam direction used for perception is toward the aircraft in the sky, and the beam direction used for communication is toward the ground. Communication equipment such as mobile phones, so the existing reference signals (e.g., CSI-RS, SSB, SRS, etc.) cannot be used as beam references for perception signals. A feasible way is to simultaneously support beam scanning of downlink perception signals, and the user equipment can determine the beam for sending uplink perception signals (i.e., transmitting spatial filters) based on the beam for receiving the downlink perception signal (i.e., receiving spatial filter parameters).

[0098] In some examples of the present disclosure, the condition in "the user equipment determines that one or more of the at least one perception configuration are effective based on at least one preset condition" may include at least a first condition for making a determination based on the user equipment's own specific physical signal and / or channel-related information (e.g., determining the effectiveness of the perception configuration). The specific physical signal and / or channel may be at least one of the following: a synchronization signal, a downlink reference signal for acquiring channel state information (e.g., CSI-RS, etc.), an uplink reference signal for channel detection (e.g., SRS, etc.), a broadcast channel, a synchronization signal / broadcast channel block (e.g., SSB), and a physical channel for sending the perception configuration.

[0099] In some examples, the specific physical signal and / or channel-related information of the user equipment itself used for determining the first condition may be at least one of the following: a synchronization signal index / broadcast channel index / SSB index determined by the user equipment during the random access process; an index of a specific physical signal and / or channel (for example, a resource index of CSI-RS, an SSB index, a synchronization signal index, a broadcast channel index, an SRS index, etc.) configured by the user equipment that has a first quasi-co-location relationship with a common downlink physical resource or a common downlink physical channel (for example, a control resource set CORESET#0 with an index of 0), wherein the first quasi-co-location relationship may be received by the same spatial filter (for example, the same spatial reception parameters), such as a co-location relationship of type D QCL type D; the user equipment is configured with an index of a specific physical signal and / or channel (for example, a resource index of CSI-RS, an SSB index, a synchronization signal index, a broadcast channel index, an SRS index, etc.) that has a first quasi-co-location relationship with a predetermined reference signal or a predetermined physical channel (for example, the predetermined reference signal or the predetermined physical channel may be at least one of the following: a downlink shared channel PDSCH and a demodulation reference signal thereof, a downlink control channel PDCCH and a demodulation reference signal thereof, CSI-RS, SRS, an uplink shared channel PUSCH and a demodulation reference signal thereof, an uplink control channel PUCCH and a demodulation reference signal thereof, etc.), wherein the first quasi-co-location relationship may be received by the same spatial filter (for example, the spatial reception parameters are the same) or sent by the same spatial filter, such as a co-location relationship of type D QCL type D.

[0100] In other examples, the user equipment performs a first condition determination based on the index of its own specific physical signal and / or channel (for example, it may be a specific physical signal and / or channel for the UE, or a specific physical signal and / or channel configured / scheduled to the UE), and the first condition may be that when the index of the specific physical signal and / or channel of the user equipment itself is the same as the first index corresponding to the i-th perception configuration, the user equipment determines that the i-th perception configuration is effective, wherein the first index is the index of the specific physical signal and / or channel corresponding to the i-th perception configuration. Wherein i is an integer less than or equal to the number of the at least one perception configuration. It should be noted that the first index may be different for different perception configurations, such as different configuration information elements / configuration values. The specific physical signals and / or channels corresponding to different perception configurations may be different. Taking the user equipment performing a first condition determination based on the SSB index determined in the random access process as an example, the first condition may be that when the SSB index determined by the user equipment in the random access process is the same as the first index corresponding to the i-th perception configuration, the user equipment determines that the i-th perception configuration is effective, wherein the first index is the SSB index corresponding to the i-th perception configuration. In this example, the SSB index can be equally replaced by other specific physical signals and / or channels, for example, a resource index of CSI-RS, a synchronization signal index, a broadcast channel index, an SRS index, etc. In other examples, a specific method for the user equipment to obtain the first index may be that the user equipment is configured with a first index corresponding to each of the at least one perception configuration, for example, each perception configuration includes an index of a specific physical signal and / or channel (for example, an SSB index, a resource index of CSI-RS, a synchronization signal index, a broadcast channel index, an SRS index, etc.), which is used by the user equipment to perform a first condition determination to determine whether the perception configuration should be effective. The principle of this design is: first, when the base station needs to perceive separately in perception areas with different horizontal directions, for different perception areas, the base station needs to receive uplink perception / send downlink perception signals with beams in different directions, and for different beam directions, user equipment with different horizontal directions needs to be selected to send corresponding uplink perception / receive corresponding downlink perception signals. Figure 4As shown, when the base station receives the corresponding uplink sensing signal with sensing receiving beam #0 and sensing receiving beam #1 respectively to realize the sensing of sensing area #0 and sensing area #1, the user equipment sending the corresponding uplink sensing signal should have different horizontal orientations (relative to the base station). For example, the base station should select UE1 and / or UE2 whose horizontal orientation relative to the base station is the same as or whose difference does not exceed a preset threshold as the horizontal orientation of sensing receiving beam #0 relative to the base station, so that it sends the uplink sensing signal for sensing within sensing area #0. Secondly, in the integrated communication sensing system, the base station can obtain the horizontal orientation of the user equipment through the horizontal orientation of the transmitting beam of the downlink signal sent to the user equipment (or the physical orientation of the receiving beam of the uplink signal received from the user equipment). This is because in the 5G millimeter wave frequency band and the higher frequency bands that may be considered for 6G in the future, in theory, the physical orientations of the downlink transmitting beam and the uplink receiving beam of the base station should point to the actual geographical location of the user equipment, otherwise the path loss may be too large, resulting in downlink or uplink transmission failure. It can be seen that the base station can determine the horizontal orientation of the user equipment according to the uplink and / or downlink signal with the user equipment, so as to configure the user equipment with a suitable geographical location to receive the perception signal or send the perception signal.

[0101] In addition to the above-mentioned first condition, the distance between the user equipment and the base station can also be used to determine the location of the user equipment as a basis for determining whether the perception configuration is effective. In some other examples of the present disclosure, the condition in "the user equipment determines that one or more of the at least one perception configuration are effective based on at least one preset condition" includes at least a second condition that is determined based on the distance-related information of the user equipment (for example, the effectiveness determination of the perception configuration). In some embodiments, the distance-related information of the user equipment may include at least one of the user equipment positioning-related information or the uplink timing advance TA. In some other examples, when the second condition is determined based on the user equipment positioning-related information, the user equipment positioning-related information may specifically be the distance between the user equipment and a specific transmission node TP (for example, a serving cell base station / transmission node, a neighboring cell base station / transmission node, another user equipment, etc.), or the time / time difference related to the user equipment positioning (for example, a downlink reference signal time difference DL RSTD, a user equipment receiving and sending time difference UE Rx-Tx time difference, etc.). Specifically, the second condition may be that when the uplink timing advance TA of the user equipment (or the distance between the user equipment and a specific transmission node TP, the time / time difference related to the positioning of the user equipment) meets the condition related to a specific threshold value, one or more perception configurations corresponding to the specific threshold value take effect. Furthermore, the correspondence between the specific threshold value and the perception configuration can be determined in at least one of the following ways: each perception configuration acquired by the user equipment includes a threshold value corresponding to the perception configuration (or a threshold condition related to the threshold value); the user equipment obtains the threshold value configuration (or threshold condition configuration) and the index of the perception configuration corresponding to the threshold value (or threshold condition), for example, the UE can receive second configuration information, and the second configuration information may include the configuration of one or more threshold conditions and the index of the perception configuration corresponding to each of the one or more threshold conditions; the user equipment obtains the threshold value configuration and the index of the perception signal transmit beam / receive beam corresponding to the threshold value (for example, TCI state index, SSB index, CSI-RS resource index, synchronization signal index, broadcast channel index, SRS index, etc.), when the perception configuration includes the index of the transmit beam / receive beam corresponding to the threshold value, the perception configuration corresponds to the threshold value. For example, the UE may receive third configuration information, wherein the third configuration information may include the configuration of one or more threshold conditions and the index of the perception signal transmit beam and / or receive beam corresponding to each of the one or more threshold conditions. When the kth first configuration contains the index of the transmit beam and / or receive beam corresponding to the first threshold condition, the kth first configuration may be determined as corresponding to the first threshold condition.Taking the second condition based on the uplink timing advance TA of the user equipment as an example, a specific example of the second condition is given below: when the following conditions are met, the perception configuration with index i takes effect on the user equipment.

[0102] δ i,L ≤N TA ≤δ i,U ,

[0103] Among them, N TA TA is the uplink timing advance of the user equipment; i,L With δ i,U is the threshold information related to the second condition corresponding to the perception configuration with index i. Alternatively, the second condition may also be δ i,L ≤N TA , or N TA ≤δ i,U And, when the second condition is based on the distance between the user equipment and the specific transmission node TP or the time / time difference related to the positioning of the user equipment, the distance between the user equipment and the specific transmission node TP or the time / time difference related to the positioning of the user equipment is used to replace N in the above formula. TA The following is the principle of the second condition design: when the base station needs to sense in different vertical sensing areas, the base station also needs to receive uplink sensing signals / send downlink sensing signals with different vertical beams for different sensing areas. For different beam directions, it may be necessary to select user equipment at different distances to send corresponding uplink sensing / receive corresponding downlink sensing signals. Figure 5 As shown, assuming that the base station needs to perform uplink sensing in the sensing area #0 and the sensing area #1 with the same horizontal orientation, when the vertical heights of the sensing area #0 and the sensing area #1 are the same, for the sensing area #0 that is closer to the base station, the vertical angle of the beam #0 for the base station to receive the uplink sensing signal is larger, and the user equipment to be selected (for example, UE1 and UE2) is closer to the base station; while for the sensing area #1 that is farther away from the base station, the vertical angle of the beam #1 for the base station to receive the uplink sensing signal is smaller, and the user equipment to be selected (for example, UE3 and UE4) is farther away from the base station. In existing wireless communication systems, especially in the 5G millimeter wave frequency band and the higher frequency bands that 6G may consider, the propagation loss of electromagnetic waves is large, which means that for a perception receiving beam direction of a base station, the distance of the user equipment sending the uplink perception signal may be only within a range. Therefore, for each perception configuration or each perception signal transmission beam / receiving beam, a threshold based on the user equipment positioning information or TA is configured respectively, so that multiple user equipment in the expected horizontal direction and within the expected distance range can send or receive perception signals, thereby ensuring that the base station obtains combining gain or diversity gain during uplink perception and / or downlink perception.

[0104] In some examples of the present disclosure, the condition in "the user equipment determines that one or more of the at least one perception configurations are effective based on at least one preset condition" includes at least a third condition of making a determination based on a timer corresponding to the perception configuration (e.g., determining the effectiveness of the perception configuration). For example, for each perception configuration in the at least one perception configuration, the perception configuration is effective within the running time of the timer corresponding to the perception configuration. The third condition may be whether the actual effective duration of the effective perception configuration exceeds the maximum duration of the timer, for example, t 0 At time t, the user equipment u determines that the i-th perception configuration in the at least one perception configuration is effective based on at least one preset condition, then at time t, t 0 ≤t≤t 0 +N, the third condition is satisfied and the i-th perception configuration is effective for the user equipment u, where T is the maximum duration of the effective timer corresponding to the i-th perception configuration. In some other examples, the specific method for determining the effectiveness of the perception configuration according to the third condition may be that when the third condition is not satisfied (for example, the timer corresponding to the perception configuration exceeds the maximum duration), the user equipment updates the effective perception configuration, for example, the user equipment shall determine whether one or more of the at least one perception configuration is effective according to other effective conditions except the third condition, and start / restart the corresponding timer for each effective perception configuration. In some specific implementations of this example, the method for the user equipment to determine the timer corresponding to the perception configuration may be that the user equipment receives a configuration message related to a timer corresponding to each of the at least one perception configuration, and determines the effective timer of the corresponding perception configuration according to the configuration message, wherein the configuration message may be the maximum duration of the effectiveness of the perception configuration. In some examples, the method for the user equipment to obtain a configuration message related to a timer corresponding to the perception configuration may be that the perception configuration obtained by the user equipment contains a timer-related configuration message, and the timer-related configuration message is used for the timer setting of the perception configuration. The purpose of this design is that, taking into account the mobility of user equipment, the user equipment should re-determine the effective perception configuration after a period of time, otherwise the perception performance may be lost due to the change of user position; and, taking into account that different perception configurations may be used for perception under different perception areas / perception needs, the corresponding perception configuration effective time should also be different. For example, when the perception area is large or the perception accuracy requirement is very low, the maximum duration of the effective timer can be longer, thereby reducing the processing complexity and impact on communication caused by the user equipment frequently updating the effective perception configuration.

[0105] In some examples of the present disclosure, the user equipment can determine that one or more of the at least one perception configuration is effective based on a combination of at least one of the first condition, the second condition, and the third condition, thereby obtaining the beneficial effect of the combination of the first condition, the second condition, and the third condition. For example, the user equipment can determine that one or more of the at least one perception configuration is effective based on the first condition and the second condition, that is, when the first condition and the second condition corresponding to the i-th perception configuration are met at the same time, the i-th perception configuration is effective. This design can ensure that the user equipment that determines the same effective perception configuration (that is, sends an uplink perception signal or receives a downlink perception signal according to the same perception configuration) meets the perception requirements of the base station in both the horizontal and vertical orientations, and realizes uplink perception or downlink perception in a specific perception area.

[0106] In some examples of the present disclosure, before the step "the user equipment determines that one or more of the at least one perception configurations are effective based on at least one preset condition", the user receives an indication of triggering perception, and determines whether to perform the step "the user equipment determines that one or more of the at least one perception configurations are effective based on at least one preset condition" and its subsequent steps according to the indication (for example, triggering the perception function, and / or not triggering the perception function). The indication of triggering perception may be at least one indication through high-layer signaling (for example, RRC signaling), MAC signaling and downlink control information DCI, for example, the user equipment receives the perception trigger indication information contained in the DCI and / or high-layer signaling, and the perception trigger indication information includes at least one of the following contents: whether to trigger the uplink perception function (for example, sending an uplink perception signal), whether to trigger the downlink perception function (for example, receiving a downlink perception signal, and performing perception measurement and / or reporting the result of the perception measurement according to the downlink perception signal). Only when the user equipment is configured with the indication of triggering perception, the user equipment can be expected to determine the effective perception configuration according to at least one preset condition, and perform subsequent uplink perception and / or downlink perception according to the effective perception configuration; otherwise, the user equipment may not perform the above steps. The purpose of this design is to enable the base station to dynamically or quasi-statically turn on or off the perception function of the user equipment according to the perception needs, saving power consumption of the user equipment and reducing the impact on communications.

[0107] In some other examples of the present disclosure, when the user determines that the effective perception configuration is related to downlink perception, the "user equipment receives the downlink perception signal and / or performs perception measurement according to the effective perception configuration" specifically also includes that the user equipment determines whether to report the measurement result after performing the downlink perception measurement according to the effective perception configuration according to the threshold threshold of the downlink perception signal receiving power, for example, when the downlink perception signal receiving power is higher than (for example, greater than, or greater than or equal to) the threshold threshold (which may be referred to as the second threshold in this article), the user equipment reports the downlink perception measurement result based on the effective perception configuration; otherwise, the downlink perception measurement result is not reported. The beneficial effect of this design is that the smaller the downlink perception signal receiving power is, the less accurate the downlink perception measurement result obtained by the user equipment is, and it is very likely to be affected by interference and noise, resulting in false detection or missed detection of the perception target object in the perception measurement. Therefore, the user equipment can determine whether the downlink perception measurement result has a high confidence probability according to the threshold threshold, and only report the credible downlink perception measurement result, so that the base station side can merge or divide the credible downlink perception measurement results, thereby improving the accuracy of the perception measurement. In some implementations of this example, the downlink perception signal received power may be at least one of the following: received power on a physical resource (e.g., a resource element, etc.) that sends the downlink perception signal or an average value of multiple received powers (e.g., an average value of multiple received powers in the time domain and / or frequency domain); power of a first detection path obtained according to the downlink perception signal or an average value of multiple powers (e.g., an average value of multiple powers related to the detection path in the time domain and / or frequency domain); power or an average value of the strongest path (e.g., the one with the highest power or the highest average power (e.g., the average power in the time domain and / or frequency domain)) in the detection path obtained according to the downlink perception signal; the sum of the powers of the first N detection paths in the detection path obtained according to the downlink perception signal, or the sum of the power averages, where N is a positive integer and may be a preset value or a configuration value; the sum of the powers of the first M strongest detection paths (e.g., the one with the highest power or the highest average power, etc.) in the detection path obtained according to the downlink perception signal, or the sum of the power averages, where M is a positive integer and may be a preset value or a configuration value. In this document, the average value of power may refer to the average value of multiple powers in the time domain and / or frequency domain, and may be used interchangeably with the average power; in addition, the average value of multiple received powers may also be referred to as the average received power, which is not limited in this disclosure. The threshold value may be a configuration value associated with the perception configuration, for example, the user equipment is configured with the threshold value δ corresponding to the i-th, i=1,2,… perception configuration i,i=1,2,…. In some other implementations of this example, a specific method for the user equipment to obtain the threshold value associated with the perception configuration may be that the user equipment obtains the threshold value configuration contained in the perception configuration, and the threshold value is used to determine whether to report the measurement result after performing downlink perception measurement according to the perception configuration. Different perception configurations can be configured with different threshold values ​​to meet different perception requirements. For example, when the i-th perception configuration is used for downlink perception measurement in a farther perception area, considering that the downlink perception signal received by the user equipment at this time has a longer propagation path and a larger path loss, the threshold value δ associated with the i-th perception configuration i Should be small; when the jth sensing configuration is used for downlink sensing measurement purposes in a relatively close sensing area, considering that the downlink sensing signal received by the user equipment at this time has a shorter propagation path and a smaller path loss, the threshold value δ associated with the jth sensing configuration is j Should be smaller.
