Description

METHOD AND APPARATUS IN A WIRELESS COMMUNICATION SYSTEM

[0001] The present invention relates to the field of wireless communication technology, and more specifically, to a method and an apparatus in a wireless communication system.

[0002] Considering the development of wireless communication from generation to generation, the technologies have been developed mainly for services targeting humans, such as voice calls, multimedia services, and data services. Following the commercialization of 5G (5th generation) communication systems, it is expected that the number of connected devices will exponentially grow. Increasingly, these will be connected to communication networks. Examples of connected things may include vehicles, robots, drones, home appliances, displays, smart sensors connected to various infrastructures, construction machines, and factory equipment. Mobile devices are expected to evolve in various form-factors, such as augmented reality glasses, virtual reality headsets, and hologram devices. In order to provide various services by connecting hundreds of billions of devices and things in the 6G (6th generation) era, there have been ongoing efforts to develop improved 6G communication systems. For these reasons, 6G communication systems are referred to as beyond-5G systems.

[0003] 6G communication systems, which are expected to be commercialized around 2030, will have a peak data rate of tera (1,000 giga)-level bit per second (bps) and a radio latency less than 100μsec, and thus will be 50 times as fast as 5G communication systems and have the 1 / 10 radio latency thereof.

[0004] In order to accomplish such a high data rate and an ultra-low latency, it has been considered to implement 6G communication systems in a terahertz (THz) band (for example, 95 gigahertz (GHz) to 3THz bands). It is expected that, due to severer path loss and atmospheric absorption in the terahertz bands than those in mmWave bands introduced in 5G, technologies capable of securing the signal transmission distance (that is, coverage) will become more crucial. It is necessary to develop, as major technologies for securing the coverage, Radio Frequency (RF) elements, antennas, novel waveforms having a better coverage than Orthogonal Frequency Division Multiplexing (OFDM), beamforming and massive Multiple-input Multiple-Output (MIMO), Full Dimensional MIMO (FD-MIMO), array antennas, and multiantenna transmission technologies such as large-scale antennas. In addition, there has been ongoing discussion on new technologies for improving the coverage of terahertz-band signals, such as metamaterial-based lenses and antennas, Orbital Angular Momentum (OAM), and Reconfigurable Intelligent Surface (RIS).

[0005] Moreover, in order to improve the spectral efficiency and the overall network performances, the following technologies have been developed for 6G communication systems: a full-duplex technology for enabling an uplink transmission and a downlink transmission to simultaneously use the same frequency resource at the same time; a network technology for utilizing satellites, High-Altitude Platform Stations (HAPS), and the like in an integrated manner; an improved network structure for supporting mobile base stations and the like and enabling network operation optimization and automation and the like; a dynamic spectrum sharing technology via collision avoidance based on a prediction of spectrum usage; an use of Artificial Intelligence (AI) in wireless communication for improvement of overall network operation by utilizing AI from a designing phase for developing 6G and internalizing end-to-end AI support functions; and a next-generation distributed computing technology for overcoming the limit of UE computing ability through reachable super-high-performance communication and computing resources (such as Mobile Edge Computing (MEC), clouds, and the like) over the network. In addition, through designing new protocols to be used in 6G communication systems, developing mechanisms for implementing a hardware-based security environment and safe use of data, and developing technologies for maintaining privacy, attempts to strengthen the connectivity between devices, optimize the network, promote softwarization of network entities, and increase the openness of wireless communications are continuing.

[0006] It is expected that research and development of 6G communication systems in hyper-connectivity, including person to machine (P2M) as well as machine to machine (M2M), will allow the next hyper-connected experience. Particularly, it is expected that services such as truly immersive eXtended Reality (XR), high-fidelity mobile hologram, and digital replica could be provided through 6G communication systems. In addition, services such as remote surgery for security and reliability enhancement, industrial automation, and emergency response will be provided through the 6G communication system such that the technologies could be applied in various fields such as industry, medical care, automobiles, and home appliances.

[0007] The present disclosure provides method and apparatus in a wireless communication system.

[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 meet the increasing demand for wireless data communication services since the deployment of 4G communication systems, efforts have been made to develop improved 5G or pre-5G communication systems. Therefore, 5G or pre-5G communication systems are also called “Beyond 4G networks” or “Post-LTE systems”.

[0065] In order to achieve a higher data rate, 5G communication systems are implemented in higher frequency (millimeter, mmWave) bands, e.g., 60 GHz bands. In order to reduce propagation loss of radio waves and increase a transmission distance, technologies such as beamforming, massive multiple-input multiple-output (MIMO), full-dimensional MIMO (FD-MIMO), array antenna, analog beamforming and large-scale antenna are discussed in 5G communication systems.

[0066] In addition, in 5G communication systems, developments of system network improvement are underway based on advanced small cell, cloud radio access network (RAN), ultra-dense network, device-to-device (D2D) communication, wireless backhaul, mobile network, cooperative communication, coordinated multi-points (CoMP), reception-end interference cancellation, etc.

[0067] In 5G systems, hybrid FSK and QAM modulation (FQAM) and sliding window superposition coding (SWSC) as advanced coding modulation (ACM), and filter bank multicarrier (FBMC), non-orthogonal multiple access (NOMA) and sparse code multiple access (SCMA) as advanced access technologies have been developed.

[0068] The following description with reference to the accompanying drawings is provided to assist in a comprehensive understanding of various embodiments of the present disclosure as defined by the claims and their equivalents. It includes various specific details to assist in that understanding but these are to be regarded as merely exemplary. Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the various embodiments described herein can be made without departing from the scope and spirit of the present disclosure. In addition, descriptions of well-known functions and constructions may be omitted for clarity and conciseness.

[0069] The terms and words used in the following description and claims are not limited to the bibliographical meanings, but, are merely used by the inventor to enable a clear and consistent understanding of the present disclosure. Accordingly, it should be apparent to those skilled in the art that the following description of various embodiments of the present disclosure is provided for illustration purpose only and not for the purpose of limiting the present disclosure as defined by the appended claims and their equivalents.

[0071] The term “include” or “may include” refers to the existence of a corresponding disclosed function, operation or component which can be used in various embodiments of the present disclosure and does not limit one or more additional functions, operations, or components. The terms such as “include” and / or “have” may be construed to denote a certain characteristic, number, step, operation, constituent element, component or a combination thereof, but may not be construed to exclude the existence of or a possibility of addition of one or more other characteristics, numbers, steps, operations, constituent elements, components or combinations thereof.

[0117] 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.

[0118] 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.

[0119] 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).

[0120] 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.

[0121] 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.

[0122] 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.

[0123] 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.

[0124] 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.

[0125] 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.

[0126] 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.

[0127] 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.

[0128] 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.

[0129] 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.

[0130] 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.).

[0131] 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.

[0132] 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.

[0133] 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.

[0134] 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).

[0135] 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.

[0136] 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.

[0137] 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.

[0138] 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).

[0139] 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 a plurality of 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.

[0140] 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.

[0141] As shown in FIG. 3b, gNB 102 includes a plurality of antennas 370a-370n, a plurality of 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.

[0142] 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.

[0143] 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.

[0144] 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.

[0145] 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.

[0146] 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.

[0147] 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, a plurality of 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.

[0148] 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.

[0149] 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.

[0150] In order to make the purpose, technical schemes and advantages of the present application clearer, the implementations of the present application will be further described in detail with reference to the accompanying drawings.

[0151] 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.

[0152] The Internet of Things (IoT) technology has the characteristics of low cost, low power consumption, and support for large-scale connections. It is usually used in application scenarios such as smart factories, smart health care, and urban management that have a large number of devices and emphasize cost control, to achieve the communication effect of connecting everything. Narrowband IoT (NB-IoT) is a kind of IoT technology that has been put into commercial applications. Compared with cell communication technology, NB-IoT has the characteristics of low-rate, low-cost, wide coverage and large capacity. It can be used as an effective complement for cell communication with a medium and high rate to as the main design objective. However, the overall design of NB-IoT is still based on the framework of cell communication, and follows the basic design concepts of cell communication in terms of device structure, signal design, etc., so its cost cannot compete with simple-structured technologies such as RFID; and its power consumption is usually supported by the device's own battery, which has a limited service life in long-term communication scenarios. Therefore, there is a need to design an IoT technology that can effectively reduce maintenance costs, with lower cost, less power consumption, and can be charged by signals in the environment; this makes up for the shortcomings of NB-IoT technology.

[0153] The present specification provides a technical design related to an IoT device that may be charged based on external signals. Such IoT devices can receive downlink signals and transmit uplink signals on the basis of charging based on their own batteries or external signals. The method by which the device receives downlink signals and transmits uplink signals is different from traditional wireless communication methods. Downlink reception is mainly based on envelope detection, and uplink transmission can be based on backscattering. Backscattering technology means that the device modulates based on a carrier wave (CW) existing in the environment or transmitted from other nodes, modulates its own information on the CW transmitted from other nodes, and reflects the modulated CW, thereby completing the transmitting of uplink signals. A transmitting device that transmits signals based on backscattering may not itself generate a carrier wave carrying information, without radio frequency circuits such as amplifiers and mixers of traditional communication devices, thereby significantly reducing the cost of the device and the requirement for power or batteries. In the present application, since the transmission and charging of such IoT devices are implemented mainly depending on ambient signal, such IoT devices are called Ambient IoT (AIoT) devices. This naming is mainly for simplicity of description and is not used to limit the scope of the devices.

[0154] In the AIoT system, signals / channels such as data and services can be directly transmitted between the base station and the AIoT node (such as tag device); it can also be transmitted via an intermediate node. For example, the base station transmits information related to the AIoT system to the intermediate node, and the intermediate node transmits data to the AIoT node; and the AIoT node transmits data to the intermediate node, and the intermediate node then transmits information related to the AIoT system to the base station.

[0155] In the present specification, for services in the AIoT system, similar principles to traditional cell communication are used, the transmission transmitted by the base station or intermediate node to the AIoT node is called downlink transmission, and the transmission transmitted by the AIoT node to the base station or intermediate node is called uplink transmission. In addition, the transmission related to the AIoT system transmitted by the base station to the intermediate node may also be called downlink transmission, and the transmission related to the AIoT system transmitted by the intermediate node to the base station may be called uplink transmission. Unless otherwise specified in the present specification, uplink / downlink transmission corresponds to the relationship between transceiving nodes, and is not used to limit whether the transmission occurs on uplink or downlink resources. For example, uplink transmission in the AIoT system may also be transmitted and received on the downlink frequency band in the FDD system, and downlink transmission in the AIoT system may also be transmitted and received on the uplink slot in the TDD system.

[0156] The base station in the present specification may also be replaced by other devices, such as communication devices, relay nodes, IAB nodes, repeater nodes, sidelink nodes as external accessories of the base station. Any mechanism applicable to the base station in the present specification can also be similarly used in the scenario where the base station is replaced by other nodes, and the description will not be repeated. The difference between the communication device of the external accessory of the base station and the base station may include: the device may transmit DL signals / channels on the UL frequency band in the FDD system and on the UL time unit in the TDD system, including transmitting DL signals / channels corresponding to communication between the base station and the UE and DL signals / channels corresponding to communication between the base station and the AIoT device.

[0157] The intermediate node in the present specification may be at least one of a relay node, an IAB node, a repeater node, a sidelink node.

[0158] In the embodiments of the present application, below a threshold can also be replaced by below or equal to the threshold, above (exceeding) the threshold can also be replaced by above or equal to the threshold, less than or equal to can also be replaced by less than, greater than or equal to can also be replaced by greater than; and vice versa.

[0159] In the embodiments of the present application, unless otherwise specified, configuration information includes at least one of information configured by the base station, indicated in the received signaling, configured by the higher layer and preconfigured. Further, it can be a set of configuration information obtained by the above methods; it can also be multiple sets of configuration information obtained by the above method, and the UE or node can select a set of configuration information to use according to predefined conditions; it can also be a set of configuration information obtained by the above method, and the set of configuration information includes multiple subsets, and the UE or node can select a subset to use according to predefined conditions.

[0160] In the embodiments of the present application, AIoT devices (such as tags, etc.) are simply called devices, and base stations or intermediate nodes that communicate with AIoT devices are collectively called readers. In the embodiments of the present application, the UE, unless otherwise limited, includes a device-type UE and / or a reader-type UE.

[0161] In the embodiments of the present application, charging the AIoT device includes charging by at least one of RF energy harvesting, non-RF energy harvesting, other charging methods (such as wired power supply), etc.

[0162] In the embodiments of the present application, the UE capabilities, unless otherwise limited, include the UE capabilities of device-type UEs and / or the UE capabilities of reader-type UEs.

[0163] In the embodiments of the present application, the transmission, unless otherwise limited, includes transmitting and receiving, including a Device to Reader (D2R) transmission and a Reader to Device (R2D) transmission.

[0164] In the embodiments of the present application, for convenience of description, the signaling in the inventory process is named in a simplified manner, but this naming does not limit the scope of protection. In the inventory process, the reader may transmit a paging message to the device, and / or at least one trigger signaling that triggers the inventory process; multiple triggering signaling that triggers the inventory process can be used to trigger multiple rounds (which can also be cycles or other descriptions corresponding to multiple cycles) of the inventory process respectively; the paging message and / or trigger signaling is referred to as Msg0 in the embodiments of the present application. After receiving Msg0, the device can transmit signaling in response to Msg0, and the signaling may carry information related to the device's ID (e.g., an N-bit random ID) and / or information related to the device's capabilities or configuration (for example, capabilities related to charging, information related to physical layer modulation methods / linear encoding methods, etc.); the signaling in response to Msg0 is referred to as Msg1 in the embodiments of the present application. After receiving Msg1, the reader may transmit signaling to the device in response to Msg1. The signaling may carry information related to whether Msg1 is successfully received and / or whether the device transmitting Msg1 can be accessed to the system; the signaling in response to Msg1 is referred to as Msg2 in the embodiments of the present application. After receiving Msg2, the device may transmit signaling in response to Msg2, which may carry information related to the device's ID (such as content related to ID such as a device's EPC), and / or data or other information that the device needs to report to the reader; the signaling in response to Msg2 is referred to as Msg3 in the embodiments of the present application. After receiving the Msg3, the reader may transmit signaling to the device in response to the Msg3, which may carry information related to further configuration of the device and / or information confirming reception of Msg3 and / or further commands or data transmitted to the device; the signaling in response to Msg3 is referred to as Msg4 in the embodiments of the present application.

[0165] For multiple rounds in the inventory process, the round corresponds to one trigger signaling and at least one of Msg1, Msg2, Msg3, and Msg4 corresponding to the trigger signaling; one inventory process may include multiple rounds, and each round may be used by the device to perform the inventory. In an exemplary embodiment, the inventory process includes in sequence:

[0166] the reader transmitting to the device a paging message to indicate information related to the device that needs to participate in the inventory process (such as the device's ID, etc.), and / or transmitting to the device one trigger signaling for triggering the inventory process to indicate information related to inventory (for example, to indicate a Q value, where a number of rounds included in the inventory process is determined based on Q, e.g., 2Q-1), the paging message and / or trigger signaling is referred to as Msg0-A, corresponding to the first round of inventory;

[0167] the device determining the inventory round corresponding to the device itself based on Msg0-A (for example, determining that the round is a random number in the range of 1 to 2Q-1), and transmitting Msg1-A to the reader if the inventory is determined to be performed in the first round;

[0168] the reader continuing to interact with the device with signaling such as Msg2-A, Msg3-A, Msg4-A, etc., if it receives Msg1-A in the first round; after the interaction ends, the first round ends;

[0169] the reader transmitting to the device one trigger signaling for triggering the inventory process, which is referred to as Msg0-B, corresponding to the second round of inventory;

[0170] the device transmitting Msg1-B to the reader if it determines to perform inventory in the second round;

[0171] the reader continuing to interact with the device with signaling such as Msg2-B, Msg3-B, Msg4-B, etc., if it receives Msg1-B in the second round; after the interaction ends, the second round ends;

[0172] and so on until the several rounds included in the inventory is completed. The inventory process ends.

[0173] This process is an exemplary embodiment of an inventory process and may be used to help illustrate the concept of rounds in inventory. The inventory process in an actual communication system may include other enhancements based on the example, for example, adjusting the inventory round according to the status of the interaction, adding command signaling interactions to the inventory process, etc.

[0174] The charging speed of an AIoT device is affected by the charging signal power and charging conversion efficiency. When the charging signal power is low, the charging speed is relatively slow, but when the energy amplifier module and other parts are running, the peak power consumption of the AIoT device is relatively high. Therefore, there may be situations in the AIoT system where the charging speed of the AIoT device is slower than the speed of energy consumption, resulting in the device being exhausted of energy, and requiring interruption of communication and charging for a period of time. The charging time may be based on the performance of the AIoT device, and the charging time may be different for different devices. Therefore, there is a need to solve the problem affecting communication based on suitable wireless resources due to the complex charging requirements of AIoT devices.

[0175] The present invention provides a method for transmitting and receiving Internet of Things wireless signaling in a communication system based on a low-cost and low-power Internet of Things device. The method enables communicating IoT devices to reasonably select wireless resources based on information related to charging, thereby reducing the impact of charging on the communication process.

[0176] In the embodiment, a first UE needs to communicate with one or more second UEs, where the communication includes a communication corresponding to an inventory and / or a communication corresponding to a command. The first UE and / or the second UE select and / or allocate transmission resources used for communication based on the information related to charging, and communicate on the selected and / or allocated transmission resources, such that during the communication process, the resources used for transmission by the first UE and the second UE can correspond to the requirement related to charging, thereby reducing the impact of charging on the communication process and enabling the communication between the first UE and the second UE more likely to be successful.

[0177] FIG. 4 illustrates a flowchart of a method performed by a first UE according to various embodiments of the present disclosure.

[0178] Referring to FIG. 4, at step S401, at least one group of transmission resources is determined according to a time gap related to first information, where the first information includes information related to charging, and where each group of transmission resources among the at least one group of transmission resources includes a first transmission resource and a second transmission resource having a correspondence, and a time gap between the first transmission resource and the second transmission resource is determined based on the time gap related to the first information. At step S402, the at least one group of transmission resources is configured to the second UE. At step S403, transmissions with the second UE are performed based on the at least one group of transmission resources.

[0179] According to various embodiments of the present application, the first UE determines a mapping (including correspondence, association, etc.) between at least one group of first transmission resources and second transmission resources according to at least one time gap related to the first information, where a time gap between at least one group or any group of first transmission resources and second transmission resources is not less than the at least one time gap related to the first information;

[0180] the first UE configures or indicates at least one of the first transmission resources and / or at least one of the second transmission resources to the second UE; at least one of the first transmission resources and / or at least one of the second transmission resources may be determined according to the mapping;

[0181] the first UE performs at least one first transmission and / or second transmission with the second UE based on at least one of the first transmission resources and / or at least one of the second transmission resources.

[0182] The second UE includes one or more UEs.

[0183] The first information includes at least one of: information related to charging, information related to a processing delay, information related to a minimum time gap between at least two transmissions, information related to a Sampling Frequency Offset (SFO) and / or a Clock Frequency Offset (CFO).

[0184] The at least one first transmission and / or second transmission includes at least one second transmission transmitted by the first UE to the second UE, and / or at least one first transmission from the second UE received by the first UE, and / or at least one first transmission transmitted by the first UE to the second UE, and / or at least one second transmission from the second UE received by the first UE. That is, transmission in various embodiments of the present specification includes transmitting and receiving. For example, from the perspective of the first UE, the first transmission corresponds to receiving, and the second transmission corresponds to transmitting; on the contrary, from the perspective of the second UE, the first transmission corresponds to transmitting, and the second transmission corresponds to receiving. For another example, the at least one first transmission includes Msg0 transmitted by the first UE, and the at least one second transmission includes Msg1 transmitted by the second UE; For another example, the at least one first transmission includes Msg1 transmitted by the second UE, and the at least one second transmission includes Msg2 transmitted by the first UE; for another example, the at least one first transmission includes Msg1 transmitted by the second UE, and the at least one second transmission includes Msg3 transmitted by the second UE; in the several examples, the transmission of the first UE corresponds to the reception of the second UE, and the transmission of the second UE corresponds to the reception of the first UE. The specific meanings of Msg1, Msg2, and Msg3 have been explained above.

[0185] Optionally, the first information includes multiple information corresponding to multiple time gaps. Optionally, the first UE communicates with multiple second UEs, and the multiple second UEs correspond to multiple first information. For example, the first information includes multiple UE capabilities related to charging and / or the multiple second UEs correspond to multiple UE capabilities related to charging, and accordingly, multiple UE capabilities related to charging correspond to multiple time gaps corresponding to charging.

[0186] Optionally, when the time gap related to the first information includes multiple time gaps, the first UE determines the mapping between the first transmission resource and the second transmission resource according to the multiple time gaps, such that for at least one or any time gap among the multiple time gaps, the time gap between at least one group of first transmission resources and second transmission resources is not less than the at least one or any time gap. For example, the time gap related to the first information includes {T1, T2, T3}, and the first UE determines the mapping between the first transmission resource and the second transmission resource, and determines that the first transmission resource R11 is mapped to the set of second transmission resources {R21, R22, R23}, where a time gap between R21 and R11 is not less than T1, a time gap between R22 and R11 is not less than T2, and a time gap between R23 and R11 is not less than T3.

[0187] Optionally, when the first information includes multiple information, the corresponding time gaps are determined according to each information or at least one information among the multiple information; the time gap related to the first information is the sum of the corresponding time gaps (optionally, the time gap corresponding to the information related to the minimum time gap between at least two transmissions is not calculated in the method). For example, the first information includes information related to charging, information related to a processing delay, information related to a Sampling Frequency Offset (SFO) and / or a Clock Frequency Offset (CFO), corresponding to time gaps t1, t2, t3 respectively; the time gap related to the first information is t1+t2+t3. Optionally, when the first information includes information related to a minimum time gap between at least two transmissions and other information, the time gap related to the first information is a maximum value of a time gap T1 determined based on the information related to the minimum time gap between at least two transmissions and a time gap T2 determined based on other information (the method of determining T2 may be the above method of determining the corresponding time gaps according to each information or at least one information among the multiple information when the first information includes multiple information, where the time gap related to the first information is the sum of the corresponding time gaps) max(T1, T2). For example, the first information includes information related to charging, information related to a processing delay, information related to a Sampling Frequency Offset (SFO) and / or a Clock Frequency Offset (CFO), corresponding to time gaps t1, t2, t3 respectively; T2 = t1+t2+t3; the time gap related to the first information is max(T1, T2), that is, max(T1, (t1+t2+t3)).

[0188] Optionally, the mapping between at least one group of first transmission resources and second transmission resources includes at least one of:

[0189] a mapping between first transmission resources corresponding to Msg0 and second transmission resources corresponding to Msg1;

[0190] a mapping between first transmission resources corresponding to Msg1 and second transmission resources corresponding to Msg2;

[0191] a mapping between first transmission resources corresponding to Msg1 and second transmission resources corresponding to Msg3;

[0192] a mapping between first transmission resources corresponding to Msg2 and second transmission resources corresponding to Msg3;

[0193] a mapping between first transmission resources corresponding to at least one of Msg1, Msg2, Msg3 and second transmission resources corresponding to Msg4.

[0194] Optionally, the determining the mapping between at least one group of first transmission resources and second transmission resources based on at least one time gap related to the first information includes at least one of (without further details, the following first / second transmission resources may be at least one or any first / second transmission resource):

[0195] determining that a time gap between first transmission resources corresponding to Msg0 and second transmission resources corresponding to Msg1 is not less than the time gap related to the first information; the first transmission resources and the second transmissions resource correspond to Msg0 and Msg1 in the same round. Further, it is determined that the time gap between the first transmission resources corresponding to Msg0 and any or at least one second transmission resource corresponding to Msg1 in the same round is not less than the time gap related to the first information. The technical effect of the method is that in one round of inventory, there is a second transmission resource that exceeds the time gap related to the first information, such that there is a second transmission resource that can be used by the second UE in one round in the inventory process, so that it can perform inventory in the round when the second UE can not perform the second transmission within a time gap shorter than the time gap related to the first information after performing the first transmission (for example, receiving Msg0) due to the UE capabilities, requirements for charging, etc. (for example, it can not transmit Msg1 within a subsequent time range less than the time gap due to insufficient energy and requiring charging); correspondingly, the second UE can select an appropriate resource to transmit Msg1 in one round of inventory to perform inventory based on information such as its own UE capabilities, requirements for charging;

[0196] determining that a time gap between first transmission resources corresponding to Msg0 and second transmission resources corresponding to Msg1 is not less than the time gap related to the first information; the first transmission resources and the second transmission resources correspond to Msg0 and Msg1 in different rounds. Further, it is determined that the time gap between the first transmission resources corresponding to the paging message and any or at least one second transmission resource corresponding to Msg1 and corresponding to a round that does not include the paging message (which may also be understood as not corresponding to the first round) is not less than the time gap related to the first information (the second transmission resource may also correspond to the inventory round corresponding to the paging message, but this scenario is the same as the previous method for Msg0 and Msgl in the same round, the previous method may be used). The technical effect of the method is that in multiple rounds of inventory, there is a second transmission resource that exceeds the time gap related to the first information, such that there is a second transmission resource that can be used by the second UE in multiple rounds in the inventory process, so that it can perform inventory in the round when the second UE can not perform the second transmission within a time gap shorter than the time gap related to the first information after performing the first transmission (for example, receiving Msg0) due to the UE capabilities, requirements for charging, etc. (for example, it can not transmit Msg1 within a subsequent time range less than the time gap due to insufficient energy and requiring charging); correspondingly, the second UE can select an appropriate inventory round and select resources to transmit Msg1 in the appropriate round to perform inventory based on information such as its own UE capabilities, requirements for charging.

[0197] Since the transmission among multiple signaling (Msg0, Msg1, Msg2, etc.) in the inventory process may result in energy consumption and corresponding charging gaps, and needs to be decoded and corresponding processing delays, and there may be a time offset in the transmission process, so there may be a similar need for a time gap related to the first information between any two signaling; therefore, Msg0 and / or Msg1 in the above method may also be replaced by Msg1, Msg2, Msg3 and any two different signaling in the inventory process / command process (for example, the first transmission resource corresponding to Msg1 and the second transmission resource corresponding to Msg2, the first transmission resource corresponding to Msg1 and the second transmission resource corresponding to Msg3, etc.). The technical effect is similar, that is, the method of determining appropriate resource mapping through the first information. The resource mapping enables the device to still select an appropriate resource that meets the time gap limitation, so that it is capable of performing the next transmission or reception on the resource, in case that the device can not perform the next transmission or reception in a subsequent certain time gap after transmitting or receiving signaling due to the UE capability or energy limitation.

[0198] Optionally, the first UE determining at least one second transmission resource configured or indicated to the second UE based on the first transmission resource (or vice versa, selects the first transmission resource based on the second transmission resource, in a similar method), and / or the second UE determining at least one second transmission resource based on the first transmission resource configured or indicated by the first UE (or vice versa, selects the first transmission resource based on the second transmission resource, in a similar method) includes: determining, based on the first transmission resource, a set of second transmission resources corresponding thereto; determining, in the set of second transmission resources, at least one resource as the second transmission resource, where a time gap between the at least one resource and the first transmission resource is not less than the time gap related to the first information.

[0199] Further, the first transmission resource corresponds to a transmission resource on which the first UE (which may be a reader) transmits Msg0, and the second transmission resource corresponds to at least one transmission resource on which the second UE (which may be one / more specific second UEs, for example, one / more second UEs corresponding to a specific UE capability) transmits Msg1. The first UE determining at least one second transmission resource configured or indicated to the second UE based on the first transmission resource (or vice versa, selects the first transmission resource based on the second transmission resource, in a similar method), and / or the second UE determining at least one second transmission resource based on the first transmission resource configured or indicated by the first UE (or vice versa, selects the first transmission resource based on the second transmission resource, in a similar method) further includes at least one of:

[0200] determining a used inventory round n in the range of 0 to N (for example, randomly selecting) in case that the inventory process includes a total of N rounds; if in the determined inventory round n, a time gap between any one or at least one of the transmission resources corresponding to the second transmission (for example, the resources corresponding to Msg1) and the first transmission (which may be Msg0, and further, it may be Msg0 in the first round) resource is less than the time gap related to the first information, n is re-determined;

[0201] determining the used inventory round n in the range of 0 to N (for example, randomly selecting) in case that the inventory process includes a total of N rounds; if in the determined inventory round n, a time gap between any one or at least one of the transmission resources corresponding to the second transmission (for example, the resources corresponding to Msg1) and the first transmission (which may be Msg0, and further, it may be Msg0 in the first round) resource is less than the time gap related to the first information, n is multiplied by a preset / configured coefficient (n' = n*x, coefficient x > 1), and again whether the time gap between any one or at least one of the resources corresponding to the second transmission and the first transmission resource is less than the time gap related to the first information is determined, which is cycled until the time gap is not less than the time gap related to the first information; if a value of the determined n' after being multiplied by the coefficient is greater than N, let n' = N, or n' is multiplied by another preset / configured coefficient (n'' = n'*y, coefficient y < 1, optionally, x*y > 1) or another preset / configured coefficient is subtracted until n" is less than or equal to N;

[0202] determining the used inventory round n in the range of n0 to N (for example, randomly selecting) in case that the inventory process includes a total of N rounds, and a time gap between the transmission resources in the first n0-1 rounds (which may be resources corresponding to the second transmission, and further, at least one / any resource corresponding to the second transmission) and the first transmission (which may be Msg0, and further, Msg0 in the first round) resource is less than the time gap related to the first information;

[0203] determining, in the selected inventory round, the second transmission resource (for example, randomly selecting and / or selecting according to UE ID / UE capability) among the transmission resources corresponding to the second transmission included in the round, and re-determining the second transmission resource in case that a time gap between the determined second transmission resource and the first transmission (which may be Msg0, and further, Msg0 in the first round or Msg0 in the selected inventory round) resource is less than the time gap related to the first information;

[0204] determining, in the selected inventory round, the second transmission resource (for example, randomly selecting and / or selecting according to UE ID / UE capability) among resources included in the round that correspond to the second transmission and with a time gap from the first transmission (which may be Msg0, and further, Msg0 in the first round or Msg0 in the selected inventory round) is not less than the time gap related to the first information.

[0205] The technical effects of each of the above methods can be considered to correspond to the technical effects of each of the methods for determining the mapping between at least one group of first transmission resources and second transmission resources, that is, determining an appropriate mapping based on the first information, and determining the second transmission resource based on the first information and the mapping; and further selecting the mapped resources suitable as the second transmission resource (for example, resources exceeding the time gap related to the first information) for the second transmission when the resources mapped to by the mapping determined based on the first information include resources suitable and unsuitable as the second transmission resource.

[0206] At least one of the first transmission resources and / or at least one of the second transmission resources may be determined according to the mapping, further including: determining at least one second transmission resource according to the mapping between the first transmission resource and the second transmission resource and according to at least one first transmission resource; and / or determining at least one first transmission resource according to the mapping between the first transmission resource and the second transmission resource and according to at least one second transmission resource.

[0207] The configuring or indicating at least one of the first transmission resources and / or at least one of the second transmission resources to the second UE further includes: configuring or indicating at least one first transmission resource according to the mapping between the first transmission resource and the second transmission resource (correspondingly, the second UE may determine at least one second transmission resource according to the mapping between the first transmission resource and the second transmission resource and according to at least one configured or indicated first transmission resource); and / or configuring or indicating at least one second transmission resource according to the mapping between the first transmission resource and the second transmission resource (correspondingly, the second UE may determine at least one first transmission resource according to the mapping between the first transmission resource and the second transmission resource and according to at least one configured or indicated second transmission resource,).

[0208] The mapping between the first transmission resource and the second transmission resource may be preset / configured / preconfigured, and / or determined based on information corresponding to the mapping. The mapping includes a static mapping (e.g., a preset / preconfigured mapping), and / or a semi-static mapping (e.g., a mapping determined according to configured information corresponding to the mapping, which may be modified by configuration information subsequently reacquired), and / or a dynamic mapping (e.g., a mapping determined according to the information corresponding to the mapping indicated in signaling, which may be signaling used by the first UE to indicate at least one of the first transmission resources and / or at least one of the second transmission resources to the second UE; the dynamic mapping may correspond to the signaling, for example, the information corresponding to the mapping indicated by the first UE in the first inventory process is used to determine the mapping between the first transmission resource and the second transmission resource in the first inventory process, and the information corresponding to the mapping indicated by the first UE in the second inventory process is used to determine the mapping between the first transmission resource and the second transmission resource in the second inventory process).

[0209] The information corresponding to the mapping may be configured or indicated by a base station to the first UE and / or the second UE, and / or configured or indicated by the first UE to the second UE, and / or configured or indicated by the second UE to the first UE.

[0210] Optionally, the first UE configuring or indicating at least one of the first transmission resources and / or at least one of the second transmission resources to the second UE further includes configuring or indicating to the second UE the information corresponding to the mapping between the first transmission resource and the second transmission resource (optionally, the method is used at least when a mapping between the first transmission resource and the second transmission resource is determined based on the information corresponding to the mapping), and / or configuring or indicating to the second UE at least one UE capability corresponding to at least one of the first transmission resource and / or at least one of the second transmission resource, and / or configuring or indicating to the second UE at least one time gap between the first transmission resource and the second transmission resource. At least one time gap between the first transmission resource and the second transmission resource may correspond to UE capabilities.

[0211] Optionally, when the first information includes information related to charging, the at least one first information related time gap includes a time gap corresponding to a charging time.
