Description

METHOD AND APPARATUS FOR MEASUREMENT AND BEAM MANAGEMENT IN A WIRELESS COMMUNICATION SYSTEM

[0001] The present disclosure relates to the field of communications. More particularly, the present disclosure relates to method and apparatus for measurement and beam management in a wireless communication system.

[0002] 5G mobile communication technologies define broad frequency bands such that high transmission rates and new services are possible, and can be implemented not only in “Sub 6GHz” bands such as 3.5GHz, but also in “Above 6GHz” bands referred to as mmWave including 28GHz and 39GHz. In addition, it has been considered to implement 6G mobile communication technologies (referred to as Beyond 5G systems) in terahertz (THz) bands (for example, 95GHz to 3THz bands) in order to accomplish transmission rates fifty times faster than 5G mobile communication technologies and ultra-low latencies one-tenth of 5G mobile communication technologies.

[0003] At the beginning of the development of 5G mobile communication technologies, in order to support services and to satisfy performance requirements in connection with enhanced Mobile BroadBand (eMBB), Ultra Reliable Low Latency Communications (URLLC), and massive Machine-Type Communications (mMTC), there has been ongoing standardization regarding beamforming and massive MIMO for mitigating radio-wave path loss and increasing radio-wave transmission distances in mmWave, supporting numerologies (for example, operating multiple subcarrier spacings) for efficiently utilizing mmWave resources and dynamic operation of slot formats, initial access technologies for supporting multi-beam transmission and broadbands, definition and operation of BWP (BandWidth Part), new channel coding methods such as a LDPC (Low Density Parity Check) code for large amount of data transmission and a polar code for highly reliable transmission of control information, L2 pre-processing, and network slicing for providing a dedicated network specialized to a specific service.

[0004] Currently, there are ongoing discussions regarding improvement and performance enhancement of initial 5G mobile communication technologies in view of services to be supported by 5G mobile communication technologies, and there has been physical layer standardization regarding technologies such as V2X (Vehicle-to-everything) for aiding driving determination by autonomous vehicles based on information regarding positions and states of vehicles transmitted by the vehicles and for enhancing user convenience, NR-U (New Radio Unlicensed) aimed at system operations conforming to various regulation-related requirements in unlicensed bands, NR UE Power Saving, Non-Terrestrial Network (NTN) which is UE-satellite direct communication for providing coverage in an area in which communication with terrestrial networks is unavailable, and positioning.

[0005] Moreover, there has been ongoing standardization in air interface architecture / protocol regarding technologies such as Industrial Internet of Things (IIoT) for supporting new services through interworking and convergence with other industries, IAB (Integrated Access and Backhaul) for providing a node for network service area expansion by supporting a wireless backhaul link and an access link in an integrated manner, mobility enhancement including conditional handover and DAPS (Dual Active Protocol Stack) handover, and two-step random access for simplifying random access procedures (2-step RACH for NR). There also has been ongoing standardization in system architecture / service regarding a 5G baseline architecture (for example, service based architecture or service based interface) for combining Network Functions Virtualization (NFV) and Software-Defined Networking (SDN) technologies, and Mobile Edge Computing (MEC) for receiving services based on UE positions.

[0006] As 5G mobile communication systems are commercialized, connected devices that have been exponentially increasing will be connected to communication networks, and it is accordingly expected that enhanced functions and performances of 5G mobile communication systems and integrated operations of connected devices will be necessary. To this end, new research is scheduled in connection with eXtended Reality (XR) for efficiently supporting AR (Augmented Reality), VR (Virtual Reality), MR (Mixed Reality) and the like, 5G performance improvement and complexity reduction by utilizing Artificial Intelligence (AI) and Machine Learning (ML), AI service support, metaverse service support, and drone communication.

[0007] Furthermore, such development of 5G mobile communication systems will serve as a basis for developing not only new waveforms for providing coverage in terahertz bands of 6G mobile communication technologies, multi-antenna transmission technologies such as Full Dimensional MIMO (FD-MIMO), array antennas and large-scale antennas, metamaterial-based lenses and antennas for improving coverage of terahertz band signals, high-dimensional space multiplexing technology using OAM (Orbital Angular Momentum), and RIS (Reconfigurable Intelligent Surface), but also full-duplex technology for increasing frequency efficiency of 6G mobile communication technologies and improving system networks, AI-based communication technology for implementing system optimization by utilizing satellites and AI (Artificial Intelligence) from the design stage and internalizing end-to-end AI support functions, and next-generation distributed computing technology for implementing services at levels of complexity exceeding the limit of UE operation capability by utilizing ultra-high-performance communication and computing resources.

[0021] Hereinafter, embodiments of the disclosure will be described in detail with reference to the accompanying drawings.

[0022] In describing the embodiments, descriptions related to technical contents well-known in the art and not associated directly with the disclosure will be omitted. Such an omission of unnecessary descriptions is intended to prevent obscuring of the main idea of the disclosure and more clearly transfer the main idea.

[0023] For the same reason, in the accompanying drawings, some elements may be exaggerated, omitted, or schematically illustrated. Further, the size of each element does not completely reflect the actual size. In the drawings, identical or corresponding elements are provided with identical reference numerals or different reference numerals.

[0024] The advantages and features of the disclosure and ways to achieve them will be apparent by making reference to embodiments as described below in detail in conjunction with the accompanying drawings. However, the disclosure is not limited to the embodiments set forth below, but may be implemented in various different forms. The following embodiments are provided only to completely disclose the disclosure and inform those skilled in the art of the scope of the disclosure, and the disclosure is defined only by the scope of the appended claims. Throughout the specification, the same or like reference numerals designate the same or like elements. Furthermore, in describing the disclosure, a detailed description of known functions or constitution incorporated herein will be omitted in the case that it is determined that the description may make the subject matter of the disclosure unnecessarily unclear. The terms which will be described below are terms defined in consideration of the functions in the disclosure, and may be different according to users, intentions of the operators, or customs. Therefore, the definitions of the terms should be made based on the contents throughout the specification.

[0025] Herein, it will be understood that each block of the flowchart illustrations, and combinations of blocks in the flowchart illustrations, may be performed based on computer program instructions. These computer program instructions may be loaded collectively onto at least one processor of a general purpose computer, special purpose computer, or other programmable data processing apparatus to produce a machine, such that the instructions, which perform through any one of, or in any combination of, the at least one processor of the computer or other programmable data processing apparatus, create means for performing the functions specified in the flowchart block(s). These computer program instructions may also be stored in a non-transitory computer usable or computer-readable memory that may direct a computer or other programmable data processing apparatus to function in a particular manner, such that the instructions stored in the computer usable or computer-readable memory produce an article of manufacture including instruction means that perform the function specified in the flowchart block(s). The computer program instructions may also be loaded onto a computer or other programmable data processing apparatus to cause a series of operational steps to be performed on the computer or other programmable data processing apparatus to produce a computer executed process such that the instructions that perform on the computer or other programmable data processing apparatus provide steps for executing the functions specified in the flowchart block(s).

[0026] Further, each block may represent a module, segment, or portion of code, which includes one or more executable instructions for executing the specified logical function(s). It should also be noted that in some alternative implementations, the functions noted in the blocks may occur out of the order. For example, two blocks(or functions) shown in succession may in fact be performed substantially concurrently or the blocks may sometimes be performed in the reverse order, depending upon the functionality involved.

[0027] As used in embodiments of the disclosure, a “~unit” may refer to a software element or a hardware element, such as a field programmable gate array (FPGA) or an application specific integrated circuit (ASIC), which performs a predetermined function. However, the term including the word “~unit” does not always have a meaning limited to software or hardware. The “~unit” may be constructed either to be stored in an addressable storage medium or to execute one or more processors. Therefore, the “~unit” includes, for example, software elements, object-oriented software elements, components such as class elements and task elements, processes, functions, properties, procedures, sub-routines, segments of a program code, drivers, firmware, micro-codes, circuits, data, database, data structures, tables, arrays, and parameters. The components and functions provided by the “~unit” may be either combined into a smaller number of components and a “~unit,” or divided into additional components and a “~unit.” Moreover, the components and “~units” may be implemented to reproduce one or more central processing units (CPUs) within a device or a security multimedia card. Further, in the embodiments, the “~unit” may include one or more processors.

[0028] It should be appreciated that the blocks in each flowchart and combinations of the flowcharts may be performed by one or more computer programs which include instructions. The entirety of the one or more computer programs may be stored in a single memory device or the one or more computer programs may be divided with different portions stored in different multiple memory devices.

[0029] Any of the functions or operations described herein can be processed by one processor or a combination of processors. The one processor or the combination of processors is circuitry performing processing and includes circuitry like an application processor (AP, e.g. a CPU), a communication processor (CP, e.g., a modem), a graphics processing unit (GPU), a neural processing unit (NPU) (e.g., an artificial intelligence (AI) chip), a Wi-Fi chip, a Bluetooth® chip, a global positioning system (GPS) chip, a near field communication (NFC) chip, connectivity chips, a sensor controller, a touch controller, a finger-print sensor controller, a display driver integrated circuit (IC), an audio CODEC chip, a universal serial bus (USB) controller, a camera controller, an image processing IC, a microprocessor unit (MPU), a system on chip (SoC), an IC, or the like.

[0030] It will be appreciated that various embodiments of the disclosure according to the claims and description in the specification can be realized in the form of hardware, software or a combination of hardware and software.

[0031] Any such software may be stored in non-transitory computer readable storage media. The non-transitory computer readable storage media store one or more computer programs (software modules), the one or more computer programs include computer-executable instructions that, when executed by one or more processors of an electronic device individually or collectively, cause the electronic device to perform a method of the disclosure.

[0032] Any such software may be stored in the form of volatile or non-volatile storage such as, for example, a storage device like read only memory (ROM), whether erasable or rewritable or not, or in the form of memory such as, for example, random access memory (RAM), memory chips, device or integrated circuits or on an optically or magnetically readable medium such as, for example, a compact disk (CD), digital versatile disc (DVD), magnetic disk or magnetic tape or the like. It will be appreciated that the storage devices and storage media are various embodiments of non-transitory machine-readable storage that are suitable for storing a computer program or computer programs comprising instructions that, when executed, implement various embodiments of the disclosure. Accordingly, various embodiments of the present disclosure may provide a program comprising code for implementing apparatus or a method as claimed in any one of the claims of this specification and a non-transitory machine-readable storage storing such a program.

[0033] Hereinafter, the determination of priority between A and B in the present disclosure may refer to various actions such as selecting the one having a higher priority based on a predefined priority rule and performing an operation corresponding thereto, or omitting or dropping an operation corresponding to the one having a lower priority.

[0034] Hereinafter, "A or B" as described in the present disclosure may be understood as "A and / or B," which may include A, or B, or both A and B.

[0035] In addition, "at least one of A, B, and C" as described in the present disclosure may be understood to include A, or B, or C, or any combination of A, B, and C.

[0036] In addition, "at least one of A, B, or C" as described in the present disclosure may be understood to include A, or B, or C, or any combination of A, B, and C.

[0037] Furthermore, "A / B" as described in the present disclosure may be understood as "A and / or B," which may include A, or B, or both A and B.

[0038] Furthermore, "A, B" as described in the present disclosure may be understood as "A and / or B," which may include A, or B, or both A and B.

[0039] Furthermore, "A and B" as described in the present disclosure may be understood as "A and / or B," which may include A, or B, or both A and B.

[0040] Furthermore, “if condition A and condition B are satisfied,” as described in the present disclosure, may not be limited to a case where both condition A and condition B are satisfied, but may be understood to include a case where either condition A or condition B is individually satisfied, both condition A and condition B are satisfied, or one or more additional conditions are satisfied in combination.

[0041] Furthermore, throughout this disclosure, ordinal terms such as "first," "second," "third," etc., (and similar qualifiers) are used merely to distinguish between different instances, occurrences, configurations, messages, stages, or aspects of elements, operations, or information as described herein. Unless the context clearly dictates otherwise, the use of such ordinal terms does not itself require that the elements, operations, or information distinguished by these terms be structurally different, numerically distinct, or substantively dissimilar. For example, a "first signal" and a "second signal" may refer to instances of the same signal transmitted at different times or containing the same core information despite minor variations, or they may refer to signals with different content or characteristics, depending on the specific context. Similarly, a "first value" and a "second value" may represent the same magnitude but measured or applied in different circumstances, or they may represent different magnitudes. The interpretation should be guided by the specific technical context, function, and relationship described in the relevant portion of the specification and claims.

[0042] Furthermore, the terms “first ~”, “second ~”, etc., as described in the present disclosure with respect to various elements (e.g., information, objects, operation, sequences, or the like), should not limit those elements. These terms may only be intended to distinguish one element from another, and may not be intended to indicate a specific order. For example, a first element could be termed a second element, and, similarly, a second element could be termed a first element.

[0043] Furthermore, even if “first ~” and “second ~” are described in the present disclosure, it may be understood that element(s) referred to by “first ~” and “second ~” may be the same or different. For example, in case of element(s) being information, first information and second information may both be same information and, in some cases, are separate and different information.

[0044] In addition, the terms “if ~” and “in case that ~” as used in the disclosure or claims may be interpreted to include the meanings of “when (or upon) ~,” “in response to ~,” “based on ~,” or “according to ~,” and may be used interchangeably with these expressions. In addition, expressions other than those exemplified herein may also be used, as long as they have substantially the same meaning and do not impair the technical features of the present disclosure.

[0045] For example, the physical layer signaling may be referred to as Layer 1 (L1) signaling and may include downlink control information (DCI). In addition, the higher layer signaling may include a medium access control (MAC) control message, a radio resource control (RRC) signaling message, a non-access stratum (NAS) signaling message, or an application layer message. The RRC signaling message may be referred to as L3 (layer 3) signaling. It should be noted, however, that the higher layer signaling is not limited to the aforementioned examples.

[0046] In addition, the term "not perform" as used in the present disclosure or claims may, in context, be understood to mean that the corresponding step is omitted or skipped. Such a term may be replaced with other terms having the same or substantially equivalent meaning.

[0047] In addition, "transmitting a message including A and B" as described in the present disclosure, may be understood as encompassing both (i) transmitting A and B in a single message, and (ii) transmitting A and B separately via multiple messages (e.g., transmitting a first message including A and a second message including B). This interpretation may also apply to messages that include two or more items (e.g., A, B, C), transmitted either together or separately.

[0048] In addition, "transmitting a message including A and transmitting a message including B" may also be interpreted as transmitting a message including A and B in a single message.

[0049] In the specific embodiments of the present disclosure described below, terms or components included in the disclosure may be expressed in singular or plural form depending on the specific embodiments presented. However, such singular or plural expressions are selected appropriately for convenience of description, and the present disclosure is not limited to a singular or plural number of components. A component expressed in the plural form may be implemented as a single component, and a component expressed in the singular form may be implemented as multiple components.

[0050] The drawings or flowcharts described below illustrate exemplary methods that may be implemented according to the principles of the present disclosure, and various modifications may be made to the methods illustrated in the flowcharts of the present disclosure. For example, although illustrated as a series of steps, various steps in each drawing or flowchart may overlap, occur in parallel, occur in a different order, or be repeated. In other examples, any step may be omitted or replaced with another step.

[0051] The methods and apparatuses proposed in the embodiments of the present disclosure are not limited to each embodiment individually, but may also be applied in combination of all or some of the embodiments proposed in the disclosure. Therefore, the embodiments of the present disclosure may be modified and applied without significantly departing from the scope of the present disclosure, as would be understood by those skilled in the art.

[0052] In this case, even if certain wordings are described differently across embodiments, they may be used interchangeably or in substitution or in combination if their underlying concepts are equivalent. For example, for the same or equivalent concept, even if one embodiment uses the expression "A" and another embodiment uses the expression "B", such expressions may be understood interchangeably, in substitution, or in combination.

[0053] The terms used in the following description to refer to access nodes, network entities, messages, interfaces between network entities, various types of identification information, and the like, are provided merely for the convenience of explanation by way of example. Therefore, the present disclosure is not limited to the terms described below, and other terms having equivalent technical meanings may also be used. Such terms may also be interchangeable with terms defined in any 3rd generation partnership project (3GPP) technical specifications (TS) where appropriate.

[0054] Hereinafter, a base station is an entity that allocates resources to terminals, and may be at least one of a gNode B, an eNode B, a Node B, a base station (BS), a wireless access unit, a BS controller, or a node on a network.

[0055] Furthermore, the base station of the present disclosure may include a split architecture comprising a central unit (CU) and a distributed unit (DU). In this structure, the CU is configured to process the higher layers of the control and user planes, while the DU is configured to process lower-layer radio resource functions. The embodiments of the present disclosure may be equally applicable to 5G base station architectures in which such CU and DU functional splits are implemented.

[0056] A terminal may include a UE, a mobile station (MS), a cellular phone, a smartphone, a computer, or a multimedia system capable of performing communication functions.

[0057] In the disclosure, a downlink (DL) refers to a radio link through which a BS transmits a signal to a UE, and an uplink (UL) refers to a radio link through which a UE transmits a signal to a BS.

[0058] Furthermore, hereinafter, 5th generation (5G) mobile communication technologies (e.g., 5G new radio (NR)), 6th generation (6G) mobile communication technologies may be described by way of example, but the embodiments of the present disclosure may also be applied to other communication systems having similar technical backgrounds or channel types. For example, newly evolved mobile communication systems developed after 5G and 6G may be included. Furthermore, based on determinations by those skilled in the art, the embodiments of the present disclosure may also be applied to other communication systems (e.g., Wi-Fi systems) through some modifications without significantly departing from the scope of the present disclosure

[0059] In the following description, the terms physical channel and signal may be used interchangeably with data or control signal. For example, the term physical downlink shared channel (PDSCH) refers to a physical channel through which data is transmitted, but the term PDSCH may also be used to refer to the data itself. That is, in the present disclosure, the expression "transmit a physical channel" may be interpreted as being equivalent to the expression "transmit data or a signal via a physical channel."

[0060] Hereinafter, in the context of the present disclosure, higher layer signaling may refer to signaling corresponding to at least one or any combination of the following: master information block (MIB), system information block (SIB) or SIB M (M = 1, 2, ...), radio resource control (RRC), or medium access control (MAC) control element (CE), or a non-access stratum (NAS) signaling message, or an application layer message. The RRC signaling message may be referred to as L3 (layer 3) signaling.

[0061] In addition, L1 signaling may refer to signaling corresponding to at least one or any combination of signaling techniques using the at least one or any combination of the following physical layer channels or signaling: physical downlink control channel (PDCCH), downlink control information (DCI), user equipment (UE)-specific DCI, group-common DCI, common DCI, scheduling DCI (e.g., DCI used for scheduling downlink or uplink data), non-scheduling DCI (e.g., DCI not used for scheduling downlink or uplink data) physical uplink control channel (PUCCH), or uplink control information (UCI). The L1 signaling message may be referred to as a physical layer signaling.

[0062] Hereinafter, the expression that information is configured by the BS, as used in the present disclosure or claims, may, in context, be understood to mean that the terminal receives the corresponding information from the BS via a physical layer signaling or a higher layer signaling. Such an expression may be replaced with other terms having the same or substantially equivalent meaning.

[0063] Hereinafter, the operational principle of the present disclosure will be described in detail with reference to the accompanying drawings.

[0064] In order to make the objectives, technical schemes and advantages of the embodiments of the present disclosure, a clearly and complete description will be made with respect to the technical schemes of the embodiments of the present disclosure, in conjunction with the accompanying drawings of the embodiments of the present disclosure.

[0111] FIG. 1 illustrates an example wireless network 100 according to various embodiments of the present disclosure. The embodiment of the wireless network 100 shown in FIG. 1 is for illustration only. Other embodiments of the wireless network 100 can be used without departing from the scope of the present disclosure.

[0112] The wireless network 100 includes a gNodeB (gNB) 101, a gNB 102, and a gNB 103. gNB 101 communicates with gNB 102 and gNB 103. gNB 101 also communicates with at least one Internet Protocol (IP) network 130, such as the Internet, a private IP network, or other data networks.

[0113] Depending on a type of the network, other well-known terms such as "base station" or "access point" can be used instead of "gNodeB" or "gNB". For convenience, the terms "gNodeB" and "gNB" are used in this patent document to refer to network infrastructure components that provide wireless access for remote terminals. And, depending on the type of the network, other well-known terms such as "mobile station", "user station", "remote terminal", "wireless terminal" or "user apparatus" can be used instead of "user equipment" or "UE". For convenience, the terms "user equipment" and "UE" are used in this patent document to refer to remote wireless devices that wirelessly access the gNB, no matter whether the UE is a mobile device (such as a mobile phone or a smart phone) or a fixed device (such as a desktop computer or a vending machine).

[0114] gNB 102 provides wireless broadband access to the network 130 for a first plurality of User Equipments (UEs) within a coverage area 120 of gNB 102. The first plurality of UEs include a UE 111, which may be located in a Small Business (SB); a UE 112, which may be located in an enterprise (E); a UE 113, which may be located in a WiFi Hotspot (HS); a UE 114, which may be located in a first residence (R); a UE 115, which may be located in a second residence (R); a UE 116, which may be a mobile device (M), such as a cellular phone, a wireless laptop computer, a wireless PDA, etc. GNB 103 provides wireless broadband access to network 130 for a second plurality of UEs within a coverage area 125 of gNB 103. The second plurality of UEs include a UE 115 and a UE 116. In some embodiments, one or more of gNBs 101-103 can communicate with each other and with UEs 111-116 using 5G, Long Term Evolution (LTE), LTE-A, WiMAX or other advanced wireless communication technologies.

[0115] The dashed lines show approximate ranges of the coverage areas 120 and 125, and the ranges are shown as approximate circles merely for illustration and explanation purposes. It should be clearly understood that the coverage areas associated with the gNBs, such as the coverage areas 120 and 125, may have other shapes, including irregular shapes, depending on configurations of the gNBs and changes in the radio environment associated with natural obstacles and man-made obstacles.

[0116] As will be described in more detail below, one or more of gNB 101, gNB 102, and gNB 103 include a 2D antenna array as described in embodiments of the present disclosure. In some embodiments, one or more of gNB 101, gNB 102, and gNB 103 support codebook designs and structures for systems with 2D antenna arrays.

[0117] Although FIG. 1 illustrates an example of the wireless network 100, various changes can be made to FIG. 1. The wireless network 100 can include any number of gNBs and any number of UEs in any suitable arrangement, for example. Furthermore, gNB 101 can directly communicate with any number of UEs and provide wireless broadband access to the network 130 for those UEs. Similarly, each gNB 102-103 can directly communicate with the network 130 and provide direct wireless broadband access to the network 130 for the UEs. In addition, gNB 101, 102 and / or 103 can provide access to other or additional external networks, such as external telephone networks or other types of data networks.

[0118] FIGs. 2a and 2b illustrate example wireless transmission and reception paths according to the present disclosure. In the following description, the transmission path 200 can be described as being implemented in a gNB, such as gNB 102, and the reception path 250 can be described as being implemented in a UE, such as UE 116. However, it should be understood that the reception path 250 can be implemented in a gNB and the transmission path 200 can be implemented in a UE. In some embodiments, the reception path 250 is configured to support codebook designs and structures for systems with 2D antenna arrays as described in embodiments of the present disclosure.

[0119] The transmission path 200 includes a channel coding and modulation block 205, a Serial-to-Parallel (S-to-P) block 210, a size N Inverse Fast Fourier Transform (IFFT) block 215, a Parallel-to-Serial (P-to-S) block 220, a cyclic prefix addition block 225, and an up-converter (UC) 230. The reception path 250 includes a down-converter (DC) 255, a cyclic prefix removal block 260, a Serial-to-Parallel (S-to-P) block 265, a size N Fast Fourier Transform (FFT) block 270, a Parallel-to-Serial (P-to-S) block 275, and a channel decoding and demodulation block 280.

[0120] In the transmission path 200, the channel coding and modulation block 205 receives a set of information bits, applies coding (such as Low Density Parity Check (LDPC) coding), and modulates the input bits (such as using Quadrature Phase Shift Keying (QPSK) or Quadrature Amplitude Modulation (QAM)) to generate a sequence of frequency-domain modulated symbols. The Serial-to-Parallel (S-to-P) block 210 converts (such as demultiplexes) serial modulated symbols into parallel data to generate N parallel symbol streams, where N is a size of the IFFT / FFT used in gNB 102 and UE 116. The size N IFFT block 215 performs IFFT operations on the N parallel symbol streams to generate a time-domain output signal. The Parallel-to-Serial block 220 converts (such as multiplexes) parallel time-domain output symbols from the Size N IFFT block 215 to generate a serial time-domain signal. The cyclic prefix addition block 225 inserts a cyclic prefix into the time-domain signal. The up-converter 230 modulates (such as up-converts) the output of the cyclic prefix addition block 225 to an RF frequency for transmission via a wireless channel. The signal can also be filtered at a baseband before switching to the RF frequency.

[0121] The RF signal transmitted from gNB 102 arrives at UE 116 after passing through the wireless channel, and operations in reverse to those at gNB 102 are performed at UE 116. The down-converter 255 down-converts the received signal to a baseband frequency, and the cyclic prefix removal block 260 removes the cyclic prefix to generate a serial time-domain baseband signal. The Serial-to-Parallel block 265 converts the time-domain baseband signal into a parallel time-domain signal. The Size N FFT block 270 performs an FFT algorithm to generate N parallel frequency-domain signals. The Parallel-to-Serial block 275 converts the parallel frequency-domain signal into a sequence of modulated data symbols. The channel decoding and demodulation block 280 demodulates and decodes the modulated symbols to recover the original input data stream.

[0122] Each of gNBs 101-103 may implement a transmission path 200 similar to that for transmitting to UEs 111-116 in the downlink, and may implement a reception path 250 similar to that for receiving from UEs 111-116 in the uplink. Similarly, each of UEs 111-116 may implement a transmission path 200 for transmitting to gNBs 101-103 in the uplink, and may implement a reception path 250 for receiving from gNBs 101-103 in the downlink.

[0123] Each of the components in FIGs. 2a and 2b can be implemented using only hardware, or using a combination of hardware and software / firmware. As a specific example, at least some of the components in FIGs. 2a and 2b may be implemented in software, while other components may be implemented in configurable hardware or a combination of software and configurable hardware. For example, the FFT block 270 and IFFT block 215 may be implemented as configurable software algorithms, in which the value of the size N may be modified according to the implementation.

[0124] Furthermore, although described as using FFT and IFFT, this is only illustrative and should not be interpreted as limiting the scope of the present disclosure. Other types of transforms can be used, such as Discrete Fourier transform (DFT) and Inverse Discrete Fourier Transform (IDFT) functions. It should be understood that for DFT and IDFT functions, the value of variable N may be any integer (such as 1, 2, 3, 4, etc.), while for FFT and IFFT functions, the value of variable N may be any integer which is a power of 2 (such as 1, 2, 4, 8, 16, etc.).

[0125] Although FIGs. 2a and 2b illustrate examples of wireless transmission and reception paths, various changes may be made to FIGs. 2a and 2b. For example, various components in FIGs. 2a and 2b can be combined, further subdivided or omitted, and additional components can be added according to specific requirements. Furthermore, FIGs. 2a and 2b are intended to illustrate examples of types of transmission and reception paths that can be used in a wireless network. Any other suitable architecture can be used to support wireless communication in a wireless network.

[0126] FIG. 3a illustrates an example UE 116 according to the present disclosure. The embodiment of UE 116 shown in FIG. 3a is for illustration only, and UEs 111-115 of FIG. 1 can have the same or similar configuration. However, a UE has various configurations, and FIG. 3a does not limit the scope of the present disclosure to any specific implementation of the UE.

[0127] UE 116 includes an antenna 301, a radio frequency (RF) transceiver 302, a transmission (TX) processing circuit 303, a microphone 304, and a reception (RX) processing circuit 305. UE 116 also includes a speaker 306, a controller / processor 307, an input / output (I / O) interface 308, an input device(s) 309, a display 310, and a memory 311. The memory 311 includes an operating system (OS) 312 and one or more applications 313.

[0128] The RF transceiver 302 receives an incoming RF signal transmitted by a gNB of the wireless network 100 from the antenna 301. The RF transceiver 302 down-converts the incoming RF signal to generate an intermediate frequency (IF) or baseband signal. The IF or baseband signal is transmitted to the RX processing circuit 305, where the RX processing circuit 305 generates a processed baseband signal by filtering, decoding and / or digitizing the baseband or IF signal. The RX processing circuit 305 transmits the processed baseband signal to speaker 306 (such as for voice data) or to controller / processor 307 for further processing (such as for web browsing data).

[0129] The TX processing circuit 303 receives analog or digital voice data from microphone 304 or other outgoing baseband data (such as network data, email or interactive video game data) from controller / 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 into an RF signal transmitted via the antenna 301.

[0130] The controller / processor 307 can include one or more processors or other processing devices and execute an OS 312 stored in the memory 311 in order to control the overall operation of UE 116. For example, the controller / processor 307 can control the reception of forward channel signals and the transmission of backward channel signals through the RF transceiver 302, the RX processing circuit 305 and the TX processing circuit 303 according to well-known principles. In some embodiments, the controller / processor 307 includes at least one microprocessor or microcontroller.

[0131] The controller / processor 307 is also capable of executing other processes and programs residing in the memory 311, such as operations for channel quality measurement and reporting for systems with 2D antenna arrays as described in embodiments of the present disclosure. The controller / processor 307 can move data into or out of the memory 311 as required by an execution process. In some embodiments, the controller / processor 307 is configured to execute the application 313 based on the OS 312 or in response to signals received from the gNB or the operator. The controller / processor 307 is also coupled to an I / O interface 308, where the I / O interface 308 provides UE 116 with the ability to connect to other devices such as laptop computers and handheld computers. I / O interface 308 is a communication path between these accessories and the controller / processor 307.

[0132] The controller / processor 307 is also coupled to the input device(s) 309 and the display 310. An operator of UE 116 can input data into UE 116 using the input device(s) 309. The display 310 may be a liquid crystal display or other display capable of presenting text and / or at least limited graphics (such as from a website). The memory 311 is coupled to the controller / processor 307. A part of the memory 311 can include a random access memory (RAM), while another part of the memory 311 can include a flash memory or other read-only memory (ROM).

[0133] Although FIG. 3a illustrates an example of UE 116, various changes can be made to FIG. 3a. For example, various components in FIG. 3a can be combined, further subdivided or omitted, and additional components can be added according to specific requirements. As a specific example, the controller / processor 307 can be divided into multiple processors, such as one or more central processing units (CPUs) and one or more graphics processing units (GPUs). Furthermore, although FIG. 3a illustrates that the UE 116 is configured as a mobile phone or a smart phone, UEs can be configured to operate as other types of mobile or fixed devices.

[0134] FIG. 3b illustrates an example gNB 102 according to the present disclosure. The embodiment of gNB 102 shown in FIG. 3b is for illustration only, and other gNBs of FIG. 1 can have the same or similar configuration. However, a gNB has various configurations, and FIG. 3b does not limit the scope of the present disclosure to any specific implementation of a gNB. It should be noted that gNB 101 and gNB 103 can include the same or similar structures as gNB 102.

[0135] As shown in FIG. 3b, gNB 102 includes multiple antennas 370a-370n, multiple RF transceivers 372a-372n, a transmission (TX) processing circuit 374, and a reception (RX) processing circuit 376. In certain embodiments, one or more of the plurality of antennas 370a-370n include a 2D antenna array. gNB 102 also includes a controller / processor 378, a memory 380, and a backhaul or network interface 382.

[0136] RF transceivers 372a-372n receive an incoming RF signal from antennas 370a-370n, such as a signal transmitted by UEs or other gNBs. RF transceivers 372a-372n down-convert the incoming RF signal to generate an IF or baseband signal. The IF or baseband signal is transmitted to the RX processing circuit 376, where the RX processing circuit 376 generates a processed baseband signal by filtering, decoding and / or digitizing the baseband or IF signal. RX processing circuit 376 transmits the processed baseband signal to controller / processor 378 for further processing.

[0137] The TX processing circuit 374 receives analog or digital data (such as voice data, network data, email or interactive video game data) from the controller / processor 378. TX processing circuit 374 encodes, multiplexes and / or digitizes outgoing baseband data to generate a processed baseband or IF signal. RF transceivers 372a-372n receive the outgoing processed baseband or IF signal from TX processing circuit 374 and up-convert the baseband or IF signal into an RF signal transmitted via antennas 370a-370n.

[0138] The controller / processor 378 can include one or more processors or other processing devices that control the overall operation of gNB 102. For example, the controller / processor 378 can control the reception of forward channel signals and the transmission of backward channel signals through the RF transceivers 372a-372n, the RX processing circuit 376 and the TX processing circuit 374 according to well-known principles. The controller / processor 378 can also support additional functions, such as higher-level wireless communication functions. For example, the controller / processor 378 can perform a Blind Interference Sensing (BIS) process such as that performed through a BIS algorithm, and decode a received signal from which an interference signal is subtracted. A controller / processor 378 may support any of a variety of other functions in gNB 102. In some embodiments, the controller / processor 378 includes at least one microprocessor or microcontroller.

[0139] The controller / processor 378 is also capable of executing programs and other processes residing in the memory 380, such as a basic OS. The controller / processor 378 can also support channel quality measurement and reporting for systems with 2D antenna arrays as described in embodiments of the present disclosure. In some embodiments, the controller / processor 378 supports communication between entities such as web RTCs. The controller / processor 378 can move data into or out of the memory 380 as required by an execution process.

[0140] The controller / processor 378 is also coupled to the backhaul or network interface 382. The backhaul or network interface 382 allows gNB 102 to communicate with other devices or systems through a backhaul connection or through a network. The backhaul or network interface 382 can support communication over any suitable wired or wireless connection(s). For example, when gNB 102 is implemented as a part of a cellular communication system, such as a cellular communication system supporting 5G or new radio access technology or NR, LTE or LTE-A, the backhaul or network interface 382 can allow gNB 102 to communicate with other gNBs through wired or wireless backhaul connections. When gNB 102 is implemented as an access point, the backhaul or network interface 382 can allow gNB 102 to communicate with a larger network, such as the Internet, through a wired or wireless local area network or through a wired or wireless connection. The backhaul or network interface 382 includes any suitable structure that supports communication through a wired or wireless connection, such as an Ethernet or an RF transceiver.

[0141] The memory 380 is coupled to the controller / processor 378. A part of the memory 380 can include an RAM, while another part of the memory 380 can include a flash memory or other ROMs. In certain embodiments, multiple instructions, such as the BIS algorithm, are stored in the memory. The plurality of instructions are configured to cause the controller / processor 378 to execute the BIS process and decode the received signal after subtracting at least one interference signal determined by the BIS algorithm.

[0142] As will be described in more detail below, the transmission and reception paths of gNB 102 (implemented using RF transceivers 372a-372n, TX processing circuit 374 and / or RX processing circuit 376) support aggregated communication with FDD cells and TDD cells.

[0143] Although FIG. 3b illustrates an example of gNB 102, various changes may be made to FIG. 3b. For example, gNB 102 can include any number of each component shown in FIG. 3a. As a specific example, the access point can include many backhaul or network interfaces 382, and the controller / processor 378 can support routing functions to route data between different network addresses. As another specific example, although shown as including a single instance of the TX processing circuit 374 and a single instance of the RX processing circuit 376, gNB 102 can include multiple instances of each (such as one for each RF transceiver).

[0144] The exemplary embodiments of the present disclosure are further described below in conjunction with the accompanying drawings.

[0145] The text and drawings are provided as examples only to help readers understand the present disclosure. They are not intended and should not be interpreted as limiting the scope of the present disclosure in any way. Although certain embodiments and examples have been provided, based on the content disclosed herein, it is obvious to those skilled in the art that modifications to the illustrated embodiments and examples can be made without departing from the scope of the present disclosure.

[0146] With the development of the 5G system, the measurement on the UE side is to provide high-quality quality guarantees for the terminal UE, and the measurement on the UE side needs to be continuously enhanced to improve the performance of the communication system. In some cases, the network cannot obtain the actual channel state of the UE more effectively. Therefore, how to provide an enhanced UE measurement solution is a problem to be solved.

[0147] Various embodiments of the present disclosure provide a method performed by a user equipment (UE) in a communication system, the method comprising: receiving a third message from a base station, wherein the third message includes information related to an event trigger, performing, by the UE, a first measurement based on the event trigger during a first time, wherein the first measurement is a layer 1 related measurement; and transmitting, by the UE, an uplink signal no later than a first delay, wherein the uplink signal includes information related to that the UE is capable of transmitting a result of the first measurement, and the first delay is defined as time between a time point when an event that will trigger a measurement report occurs over the air interface and a time point when the UE starts to transmit the uplink signal; wherein the first delay is less than the first time or Q times the first time, where Q is a positive integer greater than or equal to 1,wherein the first time is determined based on: information related to a frequency range of a serving cell of the UE; information related to a Discontinuous Reception (DRX) configuration of the UE; information relating to an event for triggering a measurement reporting; information related to a measurement reference signal (RS) of a serving beam.

[0148] Various embodiments of the present disclosure also provide a method performed by a base station in a communication system, the method comprising: transmitting a third message to a user equipment (UE), wherein the third message includes information related to an event trigger, and receiving, by the base station, an uplink signal transmitted by the UE, wherein the uplink signal is transmitted no later than a first delay, wherein the uplink signal includes information related to that the UE is capable of transmitting a result of the first measurement, and the first delay is defined as time between a time point when an event that will trigger a measurement report occurs over theair interface and a time point when the UE starts to transmit the uplink signal, wherein the first measurement is a layer 1 related measurement based on the event trigger, and the first measurement is measured during a first time; wherein the first delay is less than the first time or Q times the first time, where Q is a positive integer greater than or equal to 1, wherein the first time is determined based on: information related to a frequency range of a serving cell of the UE; information related to a Discontinuous Reception (DRX) configuration of the UE; information relating to an event for triggering a measurement reporting; information related to a measurement reference signal (RS) of a serving beam.

[0149] In the methods provided by various embodiments of the present disclosure, by the UE transmitting the uplink signal no later than the first delay and performing the first measurement based on the event trigger during the first time, it is achieved that after receiving the third message, and when the actual channel environment where the UE is located changes, for example, when the beam quality changes, it can be found as quickly as possible that the beam quality meets the event for triggering the measurement reporting, and based on the event for triggering the measurement reporting being met, it triggers to report the measurement result or indicate to the base station that the event for triggering the measurement reporting on the UE side has been met, when the event for triggering the measurement reporting is not met, the measurement result will not be reported. In this way, compared with the first measurement by non-UE-side event trigger, the system overhead is reduced, the base station can be assisted to obtain the beam measurement result of the UE side more effectively, and the communication efficiency between the network or the base station and the UE can be improved.

[0150] Exemplary embodiments of the present disclosure are further described below in conjunction with FIG. 4. FIG. 4 illustrates a schematic diagram of user equipment communicating with a base station according to an embodiment of the present disclosure. The method in an exemplary embodiment of the present disclosure may include steps 401 to 403. It can be understood that exemplary embodiments of the present disclosure may only include one or more steps among steps 401 to 403, and are not limited to including all steps.

[0151] Step 401, the UE transmits a first message and / or a second message to the base station.

[0152] As an implementation, the first message may include information related to whether the UE supports a first capability, wherein the first capability includes at least one of:

[0153] the UE being capable of receiving beams in different directions simultaneously;

[0154] the UE being capable of activating at least two antenna panels simultaneously, wherein the receiving beam of not less than one antenna panel is in a different direction than the receiving beam of the other antenna panels;

[0155] the UE being capable of receiving and / or measuring at least two different Quasi Co-Location (QCL) types of signals simultaneously;

[0157] the UE being capable of receiving and / or measuring synchronization signal block (SSB) signals in different directions simultaneously.

[0158] As an implementation, if the UE does not transmit the first message to the base station, it can be considered that the UE does not support the above-mentioned first capability.

[0159] As an implementation, the first measurement may be an L1 measurement. Further, the L1 measurement may include at least one of the following: L1-RSRP (Layer 1 Reference Signal Receiving Power) measurement, L1-SINR (Layer 1 Signal to Interference plus Noise Ratio) measurement. If the L1 measurement is based on different measurement results, the first message may be represented as multiple messages based on L1-RSRP and / or L1-SINR respectively.

[0160] As an implementation, the second message may include information related to whether the UE supports a second capability, wherein the second capability includes the UE being capable of performing a first measurement (for example, layer 1 (L1) measurement) in a case that a Receiving Time Difference (RTD) for receiving multiple measurement signals (for example, a Receiving Time Difference (RTD) of the measurement signals whose multi-transmission and reception point (TRP) or multi-carrier component arrives at the UE side) is greater than a cyclic prefix. Herein, if the L1 measurement is based on different measurement results, the second message can also be represented as multiple messages based on L1-RSRP and / or L1-SINR respectively.

[0161] Step 402, the base station transmits a third message to the UE.

[0162] As an implementation, the third message may include a Channel State Information (CSI) reporting configuration configured by the base station, such as a CSI reporting configuration of one or more serving cells.

[0163] As an implementation, the third message may include the CSI reporting configuration of one or more serving cells, and the configuration may include information related to an event trigger, for example, including at least one of the following:

[0164] - information indicating that a measurement reporting type is the event trigger,

[0165] - an event for triggering a measurement reporting;

[0166] wherein the event for triggering a measurement reporting includes at least one of:

[0167] (1) a first event, which is used to indicate that a beam quality of a serving beam (e.g., the beam quality may include L1-RSRP and / or L1-SINR) is less than a first threshold;

[0168] (2) a second event, which is used to indicate that a beam quality of at least one of configured beams to be measured (or candidate beams) is higher than the beam quality of the serving beam;

[0169] (3) a third event, which is used to indicate that the beam quality of at least one of the configured beams to be measured is higher than a beam quality of a beam corresponding to a specific transmission configuration indicator state among activated at least one transmission configuration indicator states or higher than the beam quality of the beam corresponding to the specific transmission configuration indicator state among the activated at least one transmission configuration indicator states plus a second threshold. Herein, the specific transmission configuration indicator state can be determined by the index indication or the i-th index sorted by beam quality;

[0170] (4) a fourth event, which is used to indicate that the beam quality of at least one of the configured beams to be measured is lower than a third threshold;

[0171] (5) a fifth event, which is used to indicate that the beam quality of the serving beam is lower than a fourth threshold and the beam quality of at least one of the configured beams to be measured is higher than a fifth threshold.

[0172] - a measurement reporting item: such as L1-RSRP, or L1-SINR.

[0173] - a number of the event trigger, Mcounter.

[0174] - a length of a measurement window

[0175] Step 403: After receiving the third message, the UE performs a first measurement based on the event trigger during a first time, transmits an uplink signal no later than a first delay, and determines whether to report the first measurement result based on the third message.

[0176] As an implementation, the first measurement may be an L1 measurement. Further, the L1 measurement may include at least one of the following: L1-RSRP measurement, L1-SINR measurement.

[0177] As an implementation, the first delay is defined as time between a time point when an event that will trigger a measurement report occurs over the air interface and a time point when the UE starts to transmit the uplink signal.

[0178] As an implementation, the first delay is less than the first time or a multiple of the first time (for example, Q times). As an implementation, Q is a positive integer greater than or equal to Mcounter. When Mcounteris a positive integer greater than or equal to 1, the measurement on the UE side ensures that the uplink signal is transmitted when the condition for the event trigger is satisfied by at least Mcounter. In this way, compared with a single event trigger, the reliability is improved, the potential subsequent frequent beam handover or cell handover operations of the base station can be avoided when the channel or beam changes instantaneously, and the communication reliability between the network or the base station and the UE is improved.

[0179] As an implementation, the uplink signal may include information related to that the UE is capable of transmitting a result of the first measurement.

[0180] As one such method, the reporting of the result of the first measurement based on the event for triggering the measurement reporting in the third message being satisfied by the number of the event trigger.

[0181] As an implementation, the first time may be determined based on one or more of the following information, for example:

[0182] - information related to a serving cell mode of the UE. For example, the UE is configured as a single serving cell or multi-serving cell mode (multi-serving cell mode such as intra-band CA (Intra-band Carrier Aggregation) or inter-band CA (Inter-band Carrier Aggregation)).

[0183] - information related to a frequency range of a serving cell of the UE. For example, the frequency range of each serving cell of the UE, such as frequency range 1 (FR1) and / or frequency range 2 (FR2).

[0184] - information related to a transmit receive point (TRP) mode of the UE. For example, the UE is configured in single-TRP or intra-cell or inter-cell mode.

[0185] - information related to a Discontinuous Reception (DRX) configuration of the UE, for example, the DRX parameters the UE is configured with.

[0186] - information relating to an event for triggering a measurement reporting. For example, an event for triggering a measurement reporting included in the third message.

[0187] - information related to a measurement reference signal (RS) of a serving beam. For example, the determination method of the measurement reference signal (RS) of the service beam includes: Method 1 is the QCL RS in an indicated transmission configuration indicator state (TCI state); Method 2 is a synchronization block (SSB) signal quasi co located with the QCL RS in an indicated transmission configuration indicator state (TCI state); Method 3 is an RS that is the same type as a configured measurement reference signal (RS) of a beam to be measured and wherein a set where a reference signal index of the RS is located and a set where a reference signal index of the measurement RS is located satisfy a first relationship.

[0188] - information related to whether the UE supports a first capability, wherein the first capability may include at least one of: the UE being capable of receiving beams in different directions simultaneously, the UE being capable of activating at least two antenna panels simultaneously, the UE being capable of receiving and / or measuring at least two different Quasi Co-Location (QCL) types of signals simultaneously, the UE being capable of receiving and / or measuring synchronization signal block (SSB) signals in different directions simultaneously.

[0189] - information related to whether the UE supports a second capability, wherein the second capability may include the UE being capable of performing a first measurement in a case that a Receiving Time Difference (RTD) for receiving multiple measurement signals is greater than a cyclic prefix.

[0190] - information related to at least one beam to be measured of the UE. For example, the UE is configured with one or more beams to be measured, and the configuration can be obtained by RRC (Radio Resource Control) configuration, and this disclosure does not impose any limitation on this.

[0191] - information related to a time point when the UE receives information indicating a transmission configuration indicator (TCI) state. For example, the time point (e.g., slot n) at which the UE receives a Medium Access Control (MAC) Control Element (CE) command or downlink control information (DCI) indicating a transmission configuration indicator (TCI) state.

[0192] In the method provided by various embodiments of the present disclosure, by the UE transmitting the uplink signal no later than the first delay and performing the first measurement based on the event trigger during the first time, it is achieved that after receiving the third message, and when the beam quality changes, it can be found as quickly as possible that the beam quality meets the event for triggering the measurement reporting, and based on the event for triggering the measurement reporting being met, it triggers to report the measurement result, when the event for triggering the measurement reporting is not met, it does not trigger to report the measurement result. In this way, the system overhead is reduced, the base station can be assisted to obtain the beam measurement result of the UE side more effectively, and the communication efficiency between the network or the base station and the UE can be improved.

[0193] After receiving the third message, the UE performs a first measurement based on the event trigger over a first time, transmits an uplink signal no later than a first delay, and determines whether to trigger to report the first measurement result based on the third message.

[0194] As an embodiment, the first measurement can be an L1 measurement. Further, the L1 measurement may include at least one of the following: L1-RSRP measurement, L1-SINR measurement.

[0195] As an embodiment, the first delay is defined as time between a time point when an event that will trigger a measurement report occurs over the air interface and a time point when the UE starts to transmit the uplink signal.

[0196] As an embodiment, the first delay is less than the third time. The third time is determined by one or a combination of that following condition:

[0197] fourth time; Mcounter; M2counter; M3counter; Y, fifth time; sixth time.

[0198] As an embodiment, M2counteris a non-negative integer. As an embodiment, M3counteris a non-negative integer. Y is a non-negative integer.

[0199] As an embodiment, if the third message contains the configuration of the length of the measurement window, after receiving the third message, the UE performs a first measurement based on the event trigger over a third time and transmits an uplink signal no later than a first delay. In one embodiment, the third time is (Mcounter+M2counter)* fifth time+sixth time. In another embodiment, the third time is (Mcounter+M2counterM3counter)* fifth time+sixth time. In another embodiment, the third time is (Mcounter+M2counter-Y)* fifth time+sixth time. In another embodiment, the third time is (Mcounter+M2counterM3counter-Y) * fifth time+sixth time.

[0200] Mcounteris the number of event triggers configured in the third message.

[0201] M2counteris the number of measurement occasions or instances that do not meet the event trigger condition after the counter starts, or the number of measurement occasions or instances that do not meet the event trigger condition after the first measurement occasion or instance meets the event trigger condition after the UE enters the measurement window.

[0202] M3counteris the number of measurement occasions or instances that do not meet the event trigger condition after the time point when an event that will trigger a measurement report occurs over the air interface.

[0203] In one embodiment, the fifth time is determined by the basic time unit of L1 measurement. Furthermore, the basic time unit of L1 measurement and the L1 measurement time of one or more beams related to the measurement event, if the measurement event is only related to one beam, the basic time unit of L1 measurement is determined by the L1 measurement time of the beam. If the measurement event is related to multiple beams, the basic time unit of L1 measurement is determined by the maximum of L1 measurement times of multiple beams.

[0204] For each beam, the L1 measurement time is determined by the following conditions in the embodiment. The UE may perform L1-RSRP measurement on the SSB and / or CSI-RS resources over the basic time unit of L1 measurement, that is, calculate L1-RSRP. Expressed as TL1-RSRP, it can be determined in the following ways:

[0205]

[0206] Where TRSis the period of the measurement reference signal of the beam. The measurement reference signal can be SSB or CSI-RS. for Method 1, TSSB0is a period of a QCL RS (i.e., the SSB) in the indicated transmission configuration indicator state (TCI state); for Method 2, TSSB0is a period of a synchronization block (SSB) signal quasi co located with the QCL RS in an indicated transmission configuration indicator state (TCI state); for Method 3, TSSB0is a period of an RS that is the same type as a configured measurement reference signal (RS) of a beam to be measured and whose reference signal index satisfies a defined set relationship. For the beam based on CSI-RS measurement, TCSI-RSis a period of L1 measurement for CSI-RS.

[0207] M: If timeRestrictionForChannelMeasurement is configured, it means that the measurement time of L1 measurement is restricted. M=1 if timeRestrictionForChannelMeasurement is configured, otherwise M = 3.

[0208] P: The scaling factor P may include , and the scaling factor is used to extend both the layer 1 measurement and layer 3 measurement .

[0209] As an implementation, the value of P is as follows: when Condition 1 is met, P is 1; otherwise, P is 3. However, it is not limited to this, and other representations can also be used.

[0210] Condition 1: if the SSB configured for L1-RSRP measurement outside gap is:

[0211] - not overlapped with the SSB symbols indicated by SSB-ToMeasure and 1 data symbol before each consecutive SSB symbols indicated by SSB-ToMeasure and 1 data symbol after each consecutive SSB symbols indicated by SSB-ToMeasure, given that SSB-ToMeasure is configured,

[0212] and,

[0213] - not overlapped by the RSSI symbols indicated by ss-RSSI-Measurement and 1 data symbol before each RSSI symbol indicated by ss-RSSI-Measurement and 1 data symbol after each RSSI symbol indicated by ss-RSSI-Measurement, given that ss-RSSI-Measurement is configured.

[0214] TDRXis the DRX period of the UE .

[0215] If the beam is based on FR1, N = 1.

[0216] If the beam is based on FR2, N = 8.

[0217] K is 1 or 1.5 or other preset values, and is not constrained here.

[0218] In one embodiment, the length of the measurement window in the third message should be longer than the third time.

[0219] When the Mcounteris a positive integer greater than or equal to 1, the measurement at the UE side ensures that at least the event trigger condition of the Mcounteris met before transmitting the uplink signal, thus improving the reliability compared with single event trigger, avoiding the potential subsequent frequent beam handover or cell handover of the base station when the channel or beam changes instantaneously, and improving the communication reliability between the network or the base station and the UE.

[0220] As an embodiment, the uplink signal may include information related to the result of the first measurement that the UE can transmit.

[0221] As one way, the report of the first measurement result is triggered based on the fact that the event for triggering a measurement reporting in the third message meets the number of the event trigger.

[0222] As an embodiment, the first time may be determined based on one or more of the following information, for example:

[0223] - information related to a serving cell mode of the UE. For example, the UE is configured as a single serving cell or multi-serving cell mode (multi-serving cell mode such as intra-band CA (Intra-band Carrier Aggregation) or inter-band CA (Inter-band Carrier Aggregation)).

[0227] - information relating to an event for triggering a measurement reporting. For example, an event for triggering a measurement reporting included in the third message.

[0228] - information related to a measurement reference signal (RS) of a serving beam. For example, the determination method of the measurement reference signal (RS) of the service beam includes: Method 1 is the QCL RS in an indicated transmission configuration indicator state (TCI state); Method 2 is a synchronization block (SSB) signal quasi co located with the QCL RS in an indicated transmission configuration indicator state (TCI state); Method 3 is an RS that is the same type as a configured measurement reference signal (RS) of a beam to be measured and wherein a set where a reference signal index of the RS is located and a set where a reference signal index of the measurement RS is located satisfy a first relationship.

[0229] - information related to whether the UE supports a first capability, wherein the first capability may include at least one of: the UE being capable of receiving beams in different directions simultaneously, the UE being capable of activating at least two antenna panels simultaneously, the UE being capable of receiving and / or measuring at least two different Quasi Co-Location (QCL) types of signals simultaneously, the UE being capable of receiving and / or measuring synchronization signal block (SSB) signals in different directions simultaneously.

[0230] - information related to whether the UE supports a second capability, wherein the second capability may include the UE being capable of performing a first measurement in a case that a Receiving Time Difference (RTD) for receiving multiple measurement signals is greater than a cyclic prefix.

[0231] - information related to at least one beam to be measured of the UE. For example, the UE is configured with one or more beams to be measured, and the configuration can be obtained by RRC (Radio Resource Control) configuration, and this disclosure does not impose any limitation on this.

For example, the time point (e.g., slot n) at which the UE receives a Medium Access Control (MAC) Control Element (CE) command or downlink control information (DCI) indicating a transmission configuration indicator (TCI) state.

[0233] In the method provided by various embodiments of the present disclosure, by the UE transmitting the uplink signal no later than the first delay and performing the first measurement based on the event trigger during the first time, it is achieved that after receiving the third message, and when the beam quality changes, it can be found as quickly as possible that the beam quality meets the event for triggering the measurement reporting, and based on the event for triggering the measurement reporting being met, it triggers to report the measurement result, when the event for triggering the measurement reporting is not met, it does not trigger to report the measurement result. In this way, the system overhead is reduced, the base station can be assisted to obtain the beam measurement result of the UE side more effectively, and the communication efficiency between the network or the base station and the UE can be improved.

[0234] Technical details of various embodiments of the present disclosure will be described below in conjunction with specific examples.

[0235] I. In a case that the measurement reference signal (RS) of the serving beam is based on the SSB signal: the measurement reference signal (RS) of the serving beam can be determined by the following methods: Method 1 is the QCL RS in an indicated transmission configuration indicator state (TCI state), and the QCL RS is the SSB signal with the index number ssb-index; Method 2 is a synchronization block (SSB) signal quasi co located with the QCL RS in an indicated transmission configuration indicator state (TCI state), the QCL RS signal can be CSI-RS, and the CSI-RS is quasi co located (QCL-ed) with the SSB signal with the index number ssb-index; Method 3 is an RS that is the same type as a configured measurement reference signal (RS) of a beam to be measured and wherein a set where a reference signal index of the RS is located and a set where a reference signal index of the measurement RS is located satisfy a first relationship. For example, the base station configured one or more beams to be measured. For example, the reference signal (RS) of the beam to be measured is based on SSB. Furthermore, the measurement reference signal of the serving beam and the reference signal (RS) of the beam to be measured satisfy a defined set relationship. In a certain embodiment, the SSBs are divided into N_group groups. When the index number of the measurement reference signal of the beam to be measured is index-i, the reference signal (RS) of the serving beam is the SSB signal with the other index in the same group as the index number index-i. The N_group information can be configured to the UE by the base station or agreed in the standard, and this disclosure does not impose any restrictions on this. In another embodiment, the SSBs are divided into N_group groups. When the index number of the measurement reference signal of the beam to be measured is index-i, the reference signal (RS) of the serving beam is the SSB signal with the other index in the same group as the index number index-i or the SSB signal with the other index in the group whose the group number is the group number where the index number index-i is located plus an offset O, where offset O is an integer greater than 0 or less than 0 and the absolute value is less than N_group. The N_ group information can be configured to the UE by the base station or agreed in the standard, and this disclosure does not impose any restrictions on this. The application of Method 3 can be used in some network deployments, the UE only measures the beams grouped by the network, such as the latest one or a few wide beams, without measuring all beams, enhancing a more efficient measurement mechanism in some scenarios.

[0236] The UE receives multiple beams to be measured (1 to N). The measurement reference signal of the serving beam can be determined based on the type of the measurement RS of the beam. If the type of the measurement RS is SSB, the QCL RS of the currently indicated transmission configuration indicator state (TCI state) is also SSB.

[0237] If the event for triggering a measurement reporting is the first event:

[0238] The UE may perform L1-RSRP measurement on the SSB resource during the first time, that is, calculate L1-RSRP. The first time or measurement period, denoted TL1-RSRP, may be determined by:

[0243] As an implementation, the value of P is as follows: when Condition 1 is met, P is 1; otherwise, P is 3. However, it is not limited to this, and other representations can also be used.

[0244] Condition 1: if the SSB configured for L1-RSRP measurement outside gap is:

[0245] - not overlapped with the SSB symbols indicated by SSB-ToMeasure and 1 data symbol before each consecutive SSB symbols indicated by SSB-ToMeasure and 1 data symbol after each consecutive SSB symbols indicated by SSB-ToMeasure, given that SSB-ToMeasure is configured,

[0248] TDRXis the DRX period of the UE.

[0249] If the beam is based on FR1, N = 1.

[0250] If the beam is based on FR2, N = 8.

[0257] M: If timeRestrictionForChannelMeasurement is configured, it means that the measurement time of L1 measurement is restricted. M=1 if timeRestrictionForChannelMeasurement is configured, otherwise M = 3.

[0259] As an implementation, the value of P is as follows: when Condition 1 is met, P is 1; otherwise, P is 3. However, it is not limited to this, and other representations can also be used.

[0260] Condition 1: if the SSB configured for L1-RSRP measurement outside gap is:

[0264] TDRXis the DRX period of the UE.

[0265] If the beam is based on FR1, N = 1.

[0266] If the beam is based on FR2, N and S are determined by information related to whether the UE supports the first capability and information related to whether the UE supports the second capability, respectively. For example, if the UE does not support the ability to receive beams in different directions simultaneously or the UE does not support to activate at least two antenna panels simultaneously, then N = 8. If the UE supports the ability to receive beams in different directions simultaneously or the UE supports to activate at least two antenna panels simultaneously, then N = 8 / N_set, where N_set is expressed as the number of antenna panels or the number of direction sets that the UE can support to receive beams in different directions simultaneously. If the UE supports that the UE can perform the first measurement in a case that a Receiving Time Difference (RTD) for receiving multiple measurement signals is greater than a cyclic prefix, if any symbol (OFDM symbol) in the SSB of the serving beam partially overlaps with / completely overlaps with / is adjacent to any symbol (OFDM symbol) in the SSB of the beam to be measured in the time domain, then S = V, otherwise S = 1, where V represents the number of beams that partially overlap or completely overlap or are adjacent in the time domain.

[0267] K is 1 or 1.5 or other preset values, and is not constrained here.

[0268] If the event for triggering a measurement reporting is a third event:

[0269] The UE may perform L1-RSRP measurement on the SSB resource during the first time, that is, calculate L1-RSRP. The first time or measurement period, denoted TL1-RSRP,may be determined by:

[0270]

[0271] Herein,

[0272] TSSB_active_0represents the period of the QCL RS (i.e., the SSB) in the activated 0th transmission configuration indicator state (TCI state),

[0273] TSSB_active_irepresents the period of the QCL RS (i.e., the SSB) in the activated i-th transmission configuration indicator state (TCI state),

[0274] TSSB_active_Xrepresents the period of the QCL RS (i.e., the SSB) of the activated Xth transmission configuration indicator state (TCI state), and active_X is the total number of activated transmission indication states.

[0275] TSSBjrepresents the SSB period of the j-th beam of the configured beams to be measured.

[0276] M: If timeRestrictionForChannelMeasurement is configured, it means that the measurement time of L1 measurement is restricted. M=1 if timeRestrictionForChannelMeasurement is configured, otherwise M = 3.

[0277] P: The scaling factor P may include , and the scaling factor is used to extend both the layer 1 measurement and layer 3 measurement.

[0278] As an implementation, the value of P is as follows: when Condition 1 is met, P is 1; otherwise, P is 3. However, it is not limited to this, and other representations can also be used.

[0279] Condition 1: if the SSB configured for L1-RSRP measurement outside gap is:

[0280] - not overlapped with the SSB symbols indicated by SSB-ToMeasure and 1 data symbol before each consecutive SSB symbols indicated by SSB-ToMeasure and 1 data symbol after each consecutive SSB symbols indicated by SSB-ToMeasure, given that SSB-ToMeasure is configured,

[0281] and,

[0282] - not overlapped by the RSSI symbols indicated by ss-RSSI-Measurement and 1 data symbol before each RSSI symbol indicated by ss-RSSI-Measurement and 1 data symbol after each RSSI symbol indicated by ss-RSSI-Measurement, given that ss-RSSI-Measurement is configured.

[0283] TDRXis the DRX period of the UE.

[0284] If the beam is based on FR1, N = 1.

[0285] If the beam is based on FR2, N and S are determined by information related to whether the UE supports the first capability and information related to whether the UE supports the second capability, respectively. For example, if the UE does not support the ability to receive beams in different directions simultaneously or the UE does not support to activate at least two antenna panels simultaneously, then N = 8. If the UE supports the ability to receive beams in different directions simultaneously or the UE supports to activate at least two antenna panels simultaneously, then N = 8 / N_set, where N_set is expressed as the number of antenna panels or the number of direction sets that the UE can support to receive beams in different directions simultaneously. If the UE supports that the UE can perform the first measurement in a case that a Receiving Time Difference (RTD) for receiving multiple measurement signals is greater than a cyclic prefix, if any symbol (OFDM symbol) in the SSB of the serving beam partially overlaps with / completely overlaps with / is adjacent to any symbol (OFDM symbol) in the SSB of the beam to be measured in the time domain, then S = V, otherwise S = 1, where V represents the number of beams that partially overlap or completely overlap or are adjacent in the time domain.

[0286] K is 1 or 1.5 or other preset values, and is not constrained here.

[0287] In the above various embodiments, based on the event for triggering a measurement reporting of Layer 1, the UE quickly triggers the measurement reporting result of L1 immediately when the event for triggering a measurement reporting is met. Compared with L3 measurement, it reduces the measurement delay triggered by the event, and can assist the network to perform subsequent configuration and scheduling of beam handover or activation / deactivation of the secondary cell faster, and can respond to the actual beam quality change faster, thus improving the efficiency of the beam management. For the UE supporting higher UE capabilities (for example, supporting the first capability and / or the second capability), the beam quality can be measured and reported more quickly, and the network can be assisted to perform appropriate beam handover or configuration and scheduling for different types of UE, thus improving the communication efficiency of the network.

[0288] In another embodiment, the above measured SSB can be applied to Multiple-Input Multiple-Output (MIMO) technology of multiple transmission and reception points (multi-TRP, m-TRP for short), or Carrier Aggregation (CA) and other advanced technologies. In the communication system of m-TRP and UE, each TRP can be the base station gNB or a part of the base station gNB. In the scenario of the multiple TRP and multiple carriers, in the analog beam and / or digital beam system, in frequency range 1 (FR1) or frequency range 2 (FR2) or other unspecified frequencies, since the beam increases to multiple (greater than 1) beams, therefore, a beam management mechanism that can help base stations and UEs find the best or more suitable beam to improve the overall communication rate and communication reliability of the cell is a crucial component in the communication process.

[0289] The above method can also be further applied to scenarios with greater than or equal to 2 TRPs. Two TRPs are used as an example for explanation below.

[0290] If the event for triggering a measurement reporting is a first event:

[0291] The UE may perform L1-RSRP measurement on the SSB resource during the first time, that is, calculate L1-RSRP. The first time or measurement period, denoted TL1-RSRP, may be determined by:

[0294] M: If timeRestrictionForChannelMeasurement is configured, it means that the measurement time of L1 measurement is restricted. M = 1 if timeRestrictionForChannelMeasurement is configured, otherwise M = 3.

[0295] P: The scaling factor P may include a scaling factor that extends both layer 1 measurements and layer 3 measurements. As an implementation, the value of P is as follows: when condition 1 is met, P is 1; otherwise, P is 3. However, it is not limited to this, and other representations can also be used.

If the UE supports the ability to receive beams in different directions simultaneously or the UE supports to activate at least two antenna panels simultaneously, then N = 8 / N_set, where N_set is expressed as the number of antenna panels or the number of direction sets that the UE can support to receive beams in different directions simultaneously. If the UE supports that the UE can perform the first measurement in a case that a Receiving Time Difference (RTD) for receiving multiple measurement signals is greater than a cyclic prefix, if any symbol (OFDM symbol) in the SSB of the serving beam partially overlaps with / completely overlaps with / is adjacent to any symbol (OFDM symbol) in the SSB of the beam to be measured in the time domain, then S = 2, otherwise S = 1.

[0320] K is 1 or 1.5 or other preset values, and is not constrained here.

[0321] If the event for triggering a measurement reporting is a third event:

[0322] The UE may perform L1-RSRP measurement on the SSB resource during the first time, that is, calculate L1-RSRP. The first time or measurement period, denoted TL1-RSRP,may be determined by:

[0323]

[0324] Herein, TSSB_active_0_0represents the period of the QCL RS (i.e., the SSB) in the activated 0th transmission configuration indicator state (TCI state) corresponding to TRP # 0.

[0330] As an implementation, the value of P is as follows: when Condition 1 is met, P is 1; otherwise, P is 3. However, it is not limited to this, and other representations can also be used.

[0331] Condition 1: if the SSB configured for L1-RSRP measurement outside gap is:

[0332] - not overlapped with the SSB symbols indicated by SSB-ToMeasure and 1 data symbol before each consecutive SSB symbols indicated by SSB-ToMeasure and 1 data symbol after each consecutive SSB symbols indicated by SSB-ToMeasure, given that SSB-ToMeasure is configured,

[0333] and,

[0334] - not overlapped by the RSSI symbols indicated by ss-RSSI-Measurement and 1 data symbol before each RSSI symbol indicated by ss-RSSI-Measurement and 1 data symbol after each RSSI symbol indicated by ss-RSSI-Measurement, given that ss-RSSI-Measurement is configured.

[0335] TDRXis the DRX period of the UE.

[0336] If the beam is based on FR1, N = 1.

[0337] If the beam is based on FR2, N and S are determined by information related to whether the UE supports the first capability and information related to whether the UE supports the second capability, respectively. For example, if the UE does not support the ability to receive beams in different directions simultaneously or the UE does not support to activate at least two antenna panels simultaneously, then N = 8.

[0338] K is 1 or 1.5 or other preset values, and is not constrained here.

[0339] In addition, how to more accurately measure and report the result is also an urgent problem to be solved.

[0340] As an implementation, the scheduling restriction of the first measurement may be associated with a measurement value of a Receiving Time Difference (RTD) of the UE receiving multiple measurement signals or a preset supportable maximum RTD value.

[0341] For example, when the UE performs L1-RSRP or L1-SINR, the scheduling restriction can be determined by a measurement value of a Receiving Time Difference (RTD) of the UE receiving multiple measurement signals or a preset supportable maximum RTD value, for example:

[0342] - In frequency range 1 (FR1):

[0343] -- If the UE supports simultaneousRxDataSSB-DiffNumerology, no scheduling restriction is required.

[0344] -- If the UE does not support simultaneousRxDataSSB-DiffNumerology, the UE is not expected to transmit PUCCH (Physical Uplink Control Channel) / PUSCH (Physical Uplink Shared Channel) / SRS (Sounding Reference Signal) or receive PDCCH (Physical Downlink Control Channel) / PDSCH (Physical Downlink Shared Channel) / CSI-RS for tracking / CSI-RS for CQI on SSB symbols or CSI-RS symbols (configured as L1-RSRP or RLM, BFD) or L1 symbols before or after on the SSB symbols or CSI-RS symbols. The value of L1 is based on the measured value of RTD or the preset supportable maximum RTD value. L1 = ceil (a measured value of RTD or preset supportable maximum RTD value / a length of an OFDM (Orthogonal Frequency Division Multiplexing) symbol).

[0345] - In frequency range 2 (FR2):

[0346] -- If the UE supports simultaneousRxDataSSB-DiffNumerology, scheduling restriction is not required.

[0347] -- If the UE does not support simultaneousRxDataSSB-DiffNumerology, the UE is not expected to transmit PUCCH / PUSCH / SRS or receive PDCCH / PDSCH / CSI-RS for tracking / CSI-RS for CQI on SSB symbols or CSI-RS symbols (configured as L1-RSRP or RLM, BFD) and L1 symbols before or after the SSB symbols or CSI-RS symbols. The value of L1 is based on the measured value of RTD or the preset maximum supported RTD value. L1 = ceil (a measured value of RTD or preset supportable maximum RTD value / a length of an OFDM symbol).

[0348] As an above method, the measurement restriction of the first measurement may be associated with the measured value of the RTD or a preset supportable maximum RTD value.

[0349] For example, in the measurement of L1-RSRP or L1-SINR, the measurement restriction can be restricted based on the measured value of the RTD or the preset supportable maximum RTD value:

[0350] - In frequency range 1 (FR1), on L2 overlapping or partially overlapping measurement symbols, the value of L2 is based on the measured value of the RTD or the preset supportable maximum RTD value. L2 = ceil (a measured value of RTD or preset supportable maximum RTD value / a length of an OFDM symbol).

[0351] -- If the Subcarrier Spacing (SCS) of SSB and CSI-RS is the same, there is no measurement restriction.

[0352] -- If the UE supports simultaneousRxDataSSB-DiffNumerolog, there is no measurement restriction.

[0353] -- If the UE does not support simultaneousRxDataSSB-DiffNumerology, the measurement restriction is introduced and can only measure one of L1-RSRP or RLM or BFD.

[0354] - In frequency range 2 (FR2), on L2 overlapping or partially overlapping measurement symbols, the value of L2 is based on the measured value of the RTD or the preset supportable maximum RTD value. L2 = ceil (a measured value of RTD or preset supportable maximum RTD value / a length of an OFDM symbol).

[0355] -- If the SCS of SSB and CSI-RS is the same, there is no measurement restriction.

[0356] -- If the UE supports simultaneousRxDataSSB-DiffNumerology, there is no measurement restriction.

[0357] -- If the UE does not support simultaneousRxDataSSB-DiffNumerology, measurement restriction is introduced and can only measure one of L1-RSRP or RLM or BFD.

[0358] In the case of supporting L1-RSRP or L1-SINR measurement, network deployment with larger cell radius and more accurate UE beam measurement and reporting can be supported, improving more flexible network deployment and communication efficiency between the base station and the UE.

[0359] If the event for triggering a measurement reporting is a first / second / fourth / fifth event:

[0360] As an implementation, the UE receives the PDSCH in slot n, which carries a MAC-CE activation command for indicating the transmission configuration indicator (TCI) state. If the target TCI state is known, the UE may perform the first measurement during the first time, after a first time point (slot n+ THARQ+ + TOk*(Tfirst-SSB+ TSSB-proc) / NR slot length）, and transmit the uplink signal no later than the first delay. TOk= 1, if the target TCI state is in the list of activated TCI states, and 0 otherwise. Herein, is the time when downlink data is transmitted and acknowledged. is 3 times the number of slots in the subframe. Tfirst-SSBis the time of the first received SSB after decoding the MAC-CE command and the SSB is quasi co located (QCL-ed) with the target TCI state. TSSB-procis indicated as the processing time of the SSB, for example X milliseconds.

[0361] As an implementation, if the UE receives the downlink control information (DCI) indicating the transmission configuration indicator (TCI) state in slot n, the UE may perform the first measurement during the first time after the second time point (slot n + L (second time)), and transmit the uplink signal no later than the first delay. Herein, L is the second time indicated by the system, and can be configured by the base station through the fourth message.

[0362] If the event for triggering a measurement reporting is the third event:

[0363] As an implementation, if the UE receives a PDSCH in slot n (slot n), which carries a MAC-CE activation command for updating the transmission configuration indicator (TCI) state list, if any of the activated TCI states is different from that before slot n, the UE may perform the first measurement during the first time, after a third time point (slot n + THARQ+ + (max(Tfirst-SSB_1, Tfirst-SSB_2，... , Tfirst-SSB_k, Tfirst-SSB_K) + TSSB-proc) / NR slot length）, and transmit the uplink signal no later than the first delay, wherein Tfirst-SSB_ idenotes the time of the first received SSB after decoding the MAC-CE command, wherein the SSB is the i-th SSB not in the previous activated TCI list. Herein, is the time when downlink data is transmitted and acknowledged. is 3 times the number of slots in the subframe. TSSB-procis indicated as the processing time of the SSB, for example X milliseconds.

[0364] In the above embodiment, the UE receives the base station indicating a service beam change or an activated beam change at a certain time. After that time, the UE applies layer 1 measurement based on the event trigger to more accurately reflect the real-time change of the channel or beam, and transmits an uplink signal to notify the base station, thus assisting the base station to more effectively obtain more reliable beam measurement result on the UE side, and improving the communication efficiency between the network or base station and the UE.

[0365] In the above embodiment, based on the event for triggering a measurement reporting of Layer 1, the UE quickly triggers the measurement reporting result of L1 immediately when the event for triggering a measurement reporting is met. Compared with L3 measurement, it reduces the measurement delay triggered by the event, and can assist the network to perform subsequent configuration and scheduling of beam handover or activation / deactivation of the secondary cell faster, and can respond to the actual beam quality change faster, thus improving the efficiency of the beam management.

[0366] II. In a case that the measurement reference signal (RS) of the serving beam is determined to be a CSI-RS signal:

[0367] The UE receives multiple beams to be measured (1 to N). The measurement reference signal of the serving beam can be determined based on the type of the measurement RS of the beam. If the type of the measurement RS is CSI-RS, the QCL RS of the currently indicated transmission configuration indicator state (TCI state) is also CSI-RS.

[0368] If the event for triggering a measurement reporting is a first event:

[0369] The UE may perform L1-RSRP measurement on the CSI-RS resource during the first time, that is, calculate L1-RSRP. The first time (TL1-RSRP) may be determined by:

[0370]

[0371] Herein, TCSI-RS0represents the period of the QCL RS (i.e., the CSI-RS) in the indicated transmission configuration indicator state (TCI state).

[0372] M: If timeRestrictionForChannelMeasurement is configured, it means that the measurement time of L1 measurement is restricted. M=1 if timeRestrictionForChannelMeasurement is configured, otherwise M = 3.

[0373] P: The scaling factor P may include , and the scaling factor is used to extend both the layer 1 measurement and layer 3 measurement.

[0374] As an implementation, the value of P is as follows: when Condition 1 is met, P is 1; otherwise, P is 3. However, it is not limited to this, and other representations can also be used.

[0375] Condition 1: if the SSB configured for L1-RSRP measurement outside gap is:

[0376] - not overlapped with the SSB symbols indicated by SSB-ToMeasure and 1 data symbol before each consecutive SSB symbols indicated by SSB-ToMeasure and 1 data symbol after each consecutive SSB symbols indicated by SSB-ToMeasure, given that SSB-ToMeasure is configured,

[0377] and,

Another embodiment is the RS that is the same type as a configured measurement reference signal (RS) of a beam to be measured and wherein a set where a reference signal index of the RS is located and a set where a reference signal index of the measurement RS is located satisfy a first relationship, and the reference signal index of the RS satisfy a defined set relationship.. For example, the base station configured one or more beams to be measured, the reference signal (RS) of the beam to be measured is based on CSI-RS. Furthermore, the measurement reference signal of the serving beam and the reference signal (RS) of the beam to be measured satisfy a defined set relationship. In a certain embodiment, both the QCL RS of the beam to be measured and the QCL RS of the serving are quasi co located with the SSB signal with a same index number. In this embodiment, the network only performs a measurement on the beams corresponding to CSI-RS belonging to the quasi-co-located SSB, for example, several narrow beams belonging to the same wide beam coverage area, which enhances the more effective measurement mechanism in this scenario. In another embodiment, the above-mentioned quasi-co-located SSBs may not have a same index number, but belong to the an SSB group. Alternatively, the SSBs are divided into N_group groups. When the index number of the measurement reference signal of the beam to be measured is index-i, the reference signal (RS) of the serving beam is the SSB signal with the other index in the same group as the index number index-i. The N_group information can be configured to the UE by the base station or agreed in the standard, and this disclosure does not impose any restrictions on this. The mapping relationship can also be expressed as the SSB signal or the SSB signal with the other index in the group whose the group number is the group number where the index number index-i is located plus an offset O, where offset O is an integer greater than 0 or less than 0 and the absolute value is less than N_group.

If the UE supports the first capability, for example, the UE supports the ability to receive different QCL-D beams simultaneously or the UE supports to activate at least two antenna panels simultaneously, N= ceil(maxNumberRxBeam / D / Nres_per_set). If the UE supports the second capability, if any symbol (OFDM symbol) in the SSB of the serving beam partially overlaps with / completely overlaps with / is adjacent to any symbol (OFDM symbol) in the SSB of the beam to be measured in the time domain, then S = V, otherwise S = 1, where V represents the number of beams that partially overlap or completely overlap or are adjacent in the time domain.

Compared with L3 measurement, it reduces the measurement delay triggered by the event, and can assist the network to perform subsequent configuration and scheduling of beam handover or activation / deactivation of the secondary cell faster, and can respond to the actual beam quality change faster, thus improving the efficiency of the beam management. For the UE supporting higher UE capabilities (for example, supporting the first capability and / or the second capability), the beam quality can be measured and reported more quickly, and the network can be assisted to perform appropriate beam handover or configuration and scheduling for different types of UE, thus improving the communication efficiency of the network.

[0417] If the event for triggering a measurement reporting is a first / second / fourth / fifth event:

[0418] As an implementation, the UE receives the PDSCH in slot n, which carries a MAC-CE activation command for indicating the transmission configuration indicator (TCI) state.
