Description

METHOD AND DEVICE FOR ACCESS IN A WIRELESS COMMUNICATION SYSTEM

[0001] The present application relates to the field of communications, and more specifically, to a method and device for access in 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.

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.

[0113] 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.

[0114] 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.

[0115] 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.

[0116] 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.

[0117] 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.

[0118] 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.

[0119] 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.

[0120] 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.

[0121] 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.

[0122] 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.

[0123] 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.

[0124] 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.

[0125] 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.

[0126] 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.

[0127] 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.

[0128] 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.

[0129] 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.

[0130] 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.

[0131] 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.

[0132] 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.

[0133] 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.

[0134] 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.

[0135] 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.

[0136] 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.

[0137] 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.

[0138] 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.

[0139] 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.

[0140] 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.

[0141] 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

[0142] 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."

[0143] 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.

[0144] 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.

[0145] 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.

[0146] Hereinafter, the operational principle of the present disclosure will be described in detail with reference to the accompanying drawings.

[0147] 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.

[0148] 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.

[0149] It is to be understood that the singular forms “a,” “an,” and “the” include plural referents unless the context clearly dictates otherwise. Thus, for example, reference to “a component surface” includes reference to one or more of such surfaces.

[0150] 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.

[0151] The term “or” used in various embodiments of the present disclosure includes any or all of combinations of listed words. For example, the expression “A or B” may include A, may include B, or may include both A and B.

[0152] Unless defined differently, all terms used herein, which include technical terminologies or scientific terminologies, have the same meaning as that understood by a person skilled in the art to which the present disclosure belongs. Such terms as those defined in a generally used dictionary are to be interpreted to have the meanings equal to the contextual meanings in the relevant field of art, and are not to be interpreted to have ideal or excessively formal meanings unless clearly defined in the present disclosure.

[0153] The various embodiments of the present disclosure may be applied to various communication systems, such as: a global system for mobile communications (GSM) system, a code division multiple access (CDMA) system, a wideband code division multiple access (WCDMA) system, a general packet radio service (GPRS), a long term evolution (LTE) system, an LTE frequency division duplex (FDD) system, an LTE time division duplex (TDD) system, an universal mobile telecommunications system (UMTS), a worldwide interoperability for microwave access (WiMAX) communication system, a 5th generation (5G) system or new radio (NR), etc. In addition, the various embodiments of the present disclosure may be applied to future oriented communication technologies.

[0154] 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".

[0155] 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.

[0156] 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.

[0157] 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.

[0158] 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.

[0159] 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.

[0160] 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).

[0161] 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.

[0162] 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.

[0163] 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.

[0164] 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.

[0165] 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.

[0166] 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.

[0167] 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.

[0168] 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.

[0169] 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.

[0170] 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.

[0171] 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.)

[0172] 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.

[0173] 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.

[0174] 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.

[0175] 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).

[0176] 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.

[0177] 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.

[0178] 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.

[0179] 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).

[0180] 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.

[0181] 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.

[0182] 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.

[0183] 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.

[0184] 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.

[0185] 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.

[0186] 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.

[0187] 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.

[0188] 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.

[0189] 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.

[0190] 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).

[0200] The transmission links of the wireless communication system mainly comprise downlink communication links by the 5G gNB to the user equipment (UE) and uplink communication links by the UE to the network.

[0201] Nodes for positioning measurements in a wireless communication system, such as current wireless communication systems, include a UE that initiates a positioning request message, a Location Management Function (LMF) for positioning of the UE and transmission of positioning assistance data, a gNB or Transmission-Reception Point (TRP) that broadcasts positioning assistance data and makes uplink positioning measurements, a UE for downlink positioning measurements. Furthermore, the method of the present invention may also be extended to apply in other communication systems, e.g. automotive communication (V2X), e.g. sidelink communication, in such case the transmission reception point or UE may be any device in V2X.

[0202] Transmissions in a wireless communication system include transmissions by a base station (gNB) to a user equipment (UE), referred to as downlink transmissions, corresponding slots referred to as downlink slots, and transmissions by a UE to a base station device, referred to as uplink transmissions, corresponding slots referred to as uplink slots.

[0203] In downlink communication of a wireless communication system, the system transmits synchronization signals and broadcast channels to users over a synchronization signal block (synchronization signal / Physical Broadcasting channel block, SSB) with a periodicity, the periodicity is a synchronization signal block periodicity (SSB periodicity), otherwise known as a synchronization signal block burst periodicity (SSB burst periodicity). At the same time, the base station configures a physical random access channel configuration period (PRACH configuration period) in which a certain number of random access transmission occasions (also referred to as PRACH transmission occasions, ROs) are configured, the configured ROs being determined by a certain validity rule to obtain valid ROs; and it is satisfied that within an association period (a certain length of time) all SSBs can be mapped onto the corresponding valid ROs, in an SSB to RO mapping cycle, all SSBs within one SSB periodicity can be exactly mapped onto the required random access resources, there may be one or more mapping cycles within one association period. One SSB-to-RO association pattern period contains one or more association periods, and the SSB-to-RO mapping patterns in each association pattern period are the same.

[0204] In New Radio (NR) communication systems, before radio resource control is established, such as during the random access process, the performance of random access directly affects the user experience. In traditional wireless communication systems, such as LTE and LTE-Advanced, or in 5G or NR systems, the random access process is applied to multiple scenarios such as establishing initial link, cell handover, re-establishing uplink link, RRC connection reestablishment, etc., and is divided into contention-based random access and contention-free random access according to whether the user monopolizes the preamble sequence resources. Since in contention-based random access, each user selects a preamble sequence from the same preamble sequence resource when trying to establish an uplink link, multiple users may select the same preamble sequence and transmit it to the base station. Therefore, the contention resolution mechanism is an important research direction in random access. How to reduce the probability of collision and how to quickly resolve collision that have occurred are key metric that affect the performance of random access.

[0205] FIG. 4 illustrates a schematic diagram of a 4-step random access procedure. For example, the contention-based random access process is divided into four steps, as shown in FIG.4. In the first step, the user randomly selects a preamble sequence from the preamble sequence (also interchangeably referred to as "preamble" herein) resource pool and transmits it to the base station. The base station performs correlation detection on the received signal, thereby identifying the preamble sequence transmitted by the user; in the second step, the base station transmits to the user a random access response (RAR), including a random access preamble sequence identifier, a timing advance command determined based on the time delay estimation between the user and the base station, and a temporary cell-radio network temporary identifier (C-RNTI), and the time-frequency resources allocated for next uplink transmission of the user; the user shall search for the PDCCH carrying such feedback based on the RA-RNTI associated with the PRACH occasion where the random access preamble sequence is transmitted. The RA-RNTI associated with the PRACH occasion (RO) for transmitting the random access preamble sequence is calculated according to the following formula:

[0206] RA-RNTI = 1+s_id+14 × t_id+14 × 80 × f_id+14 × 80 × 8 × ul_carrier_id,

[0207] where s_id is the index of the first OFDM symbol of this PRACH occasion (0 < s_id < 14), t_id is the index of the first slot of this PRACH occasion in the system frame (0 < t_id < 80), where the subcarrier spacing used to determine t_id is based on the value of μ specified in TS 38.211, section 5.3. 2, for μ = {0, 1, 2, 3}, for μ = {5, 6}, t_id is the index of the 120 kHz slot containing the PRACH occasion in the system frame (0 < t_id < 80), f_id is the index of the PRACH occasion in frequency domain (0 < f_id < 8), UL_carrier_id is the UL carrier used for random access preamble transmission (0 for normal uplink (NUL) carrier, 1 for SUL carrier).

[0208] In the third step, the user transmits a third message (message 3, Msg3) to the base station based on the information in the RAR. Msg3 contains information such as user terminal identifier and RRC connection request and the like, where the user terminal identifier is unique to the user and is used to resolve contention; in the fourth step, the base station transmits a contention resolution identifier to the user, including the identifier of the user terminal that wins in the contention resolution. After detecting its own identifier, the user upgrades the temporary C-RNTI to C-RNTI, transmits an ACK signal to the base station, completing the random access procedure, and waits for the scheduling of the base station. Otherwise, the user will start a new random access procedure after a delay of time.

[0209] For the contention-free random access procedure, since the base station knows the user identifier, and may allocates a preamble sequence to the user. Therefore, when transmitting the preamble sequence, the user does not need to randomly select a sequence, but uses the allocated preamble sequence. After detecting the allocated preamble sequence, the base station will transmit a corresponding random access response, including timing advance and uplink resource allocation information. After receiving the random access response, the user considers that the uplink synchronization has been completed and waits for further scheduling of the base station. Therefore, the contention-free random access procedure only includes two steps: step 1 is to transmit the preamble sequence; step 2 is to transmit a random access response.

[0210] For example, the random access procedure is applicable to the following scenarios:

[0211] 1. Initial access in RRC_IDLE;

[0212] 2. Re-establish RRC connection;

[0213] 3. Cell handover;

[0214] 4. Downlink data arrives in RRC connected state and requests a random access procedure (when the uplink is asynchronous);

[0215] 5. Uplink data arrives in the RRC connected state and requests a random access procedure (when the uplink is asynchronous or no resources are allocated to the scheduling request in the PUCCH resources);

[0216] 6. Positioning.

[0217] When accessing a wireless communication system, the UE needs to find a (transmitting and / or receiving) beam that is operable for communicating with the base station. In the traditional method, the UE, by receiving multiple reference signals transmitted in time division multiplexing by the base station, for example, an SSB burst, in which multiple reference signals may correspond to different beam directions, and by measuring different reference signals, the UE determines the appropriate downlink beam direction. However, the delay in this method is relatively large, for example, the UE may usually need to measure multiple SSBs to obtain sufficient information to access the system. Therefore, how to improve the design to enable a suitable (transmit or receive) beam direction to be obtained quickly is a problem that needs to be solved. On the other hand, considering the differences in UE capabilities, for example, some UEs have the capability to receive large bandwidth signals, and by receiving SSBs that are only time division multiplexed to access the system, such capability of the UEs cannot be fully utilized, such that UEs that support receiving large bandwidth signals need to access the system in a basically similar manner and experience basically the same statistical delay as UEs that can only receive small bandwidth signals.

[0218] In an embodiment of the present invention, a method and device for system access will be introduced. The method designs a reference signal burst including multiple reference signals multiplexed in frequency domain in the same time unit by considering Joint Phase-Time Arrays (JPTA) related technology, and is applied to signal transmission at the transmitting end and / or signal reception at the receiving end. In this way, the differences in UE capabilities in receiving signal bandwidth may be taken into account, and the capabilities of UEs capable of receiving large bandwidth signals may be fully utilized, so that UEs, such as UEs with large bandwidth signal receiving capabilities, may receive large bandwidth signals composed of frequency division multiplexed SSBs, and accordingly use a large initial bandwidth to access the system, so that such UEs may access the system more quickly. In addition, according to the method of the present disclosure, after a UE determines the bandwidth for communication based on the frequency division multiplexed SSBs, it may use the bandwidth for both initial access and subsequent communications without determining the bandwidth again. According to the method provided by the embodiment of the present disclosure, it is beneficial for the base station and / or the UE to quickly determine the appropriate transmit direction and / or receive direction of the signals and / or quickly access the system, or may also efficiently determine the bandwidth for communication. The solution is explained in the present disclosure by considering the joint phase-time arrays related technology, but this is only exemplary and is for the convenience of the inventor to fully describe its technical concepts and technical principles, but not for the purpose of limiting the principles of the present disclosure to the system access method using joint phase-time arrays.

[0219] It should be understood that although most of the description of the present disclosure describes the system access solutions in terms of design improvements by considering JPTA, the principles disclosed in the present disclosure may be equally applied to scenarios using other technical solutions. For example, for scenarios where beam codebook design is optimized, or scenarios with multi-antenna panels, the technology of the present disclosure may also be applied.

[0220] The system access in the present invention may include two parts, the transmission and / or reception of a general downlink reference signal (gDRS), and / or the transmission and / or reception of a general uplink reference signal (gURS). In the present invention, SSB is used as an example of a general downlink reference signal related to system access to describe the solution, but this is only exemplary, and SSB may also be replaced by other gDRSs, such as CSI-RS, PRS, etc. In the present invention, PRACH is used as an example of a general uplink reference signal related to system access to describe the solution, but this is only exemplary, and PRACH may also be replaced by other gURSs, such as SRS.

[0221] It should be noted that the BWP (bandwidth part) involved in the present invention is only an example and may be replaced by a section of frequency domain resources, where the frequency domain resources may be a section of frequency domain resources on one carrier, or a section of frequency domain resources occupying multiple carriers, which is not limited here.

[0222] The method provided by the present invention may comprise a combination of one or more of the following operations:

[0223] - The UE receives gDRSs transmitted by such as a network device (such as a base station, etc.), where:

[0224] -- In an implementation, the gDRSs may be SSB signals, and the UE receives multiple SSBs occupying different frequency domain units (frequency division multiplexed SSBs) in the same time unit, where the frequency domain unit is the number of frequency domain PRBs occupied by one SSB (for example, 20 PRBs), and the time unit is the number of time domain symbols occupied by one SSB (for example, 4);

[0225] -- In an implementation, the above-mentioned frequency division multiplexed SSBs belong to part of an SSB pattern, and the SSB pattern may be preset by the protocol or configurable;

[0226] --- Note that in the present invention, the SSB pattern composed of SSBs transmitted on N time units and the same frequency domain unit (for example, SSBs that are only time division multiplexed, or called not frequency division multiplexed SSBs) is called the first type SSB pattern (or written as the first pattern). In the first type SSB pattern, the total number of SSBs N is the same as the number of time units X in the SSB pattern, N = X (for example, N = 4, 8, 64...), the number of frequency domain SSBs Y = 1; an SSB pattern including multiple SSBs in frequency domain (or called frequency division multiplexed SSBs) is called the second-type SSB pattern (or written as the second pattern or the first mode). In the second-type SSB pattern, the number of frequency domain SSBs Y is not equal to 1, for example, Y is an integer greater than or equal to 2, the number of time domain SSBs X (or called the number of time domain units X occupied by SSBs) may be 1 or greater than 1, the total number of SSBs in the SSB pattern where N, X, Y are positive integers; in addition, an SSB belonging to the second-type SSB burst is called the second-type SSB in the present invention. It is meant the second-type SSB, if not explicitly described in the description of this application as the first type or the second-type SSB, unless otherwise indicated in the context.

[0229] ----- Optionally, when N is an odd number (1, 3, 5, 7, 9...), taking N = 3 as an example, as shown in FIG. 5, SSB #0, SSB #1 and SSB #2 are transmitted in the same time unit 0 and on different frequency domain units (SSB #0, SSB #1, and SSB #2 are transmitted on frequency domain units 0, 1, and 2, respectively);

[0230] ------ the index of the reference SSB (which may also be referred to as the reference downlink reference signal or the first downlink reference signal, or the reference SSB may be used as an example of the reference downlink reference signal) in frequency domain SSB pattern is a combination of one or more of:

[0231] ------- the SSB with an index of floor (N / 2) or (N-l) / 2 (when N = 3, the index of the reference SSB is 1 (SSB #1)), where floor denotes a function that rounds down;

[0232] ------- the SSB corresponding to the smallest SSB index (0) or the lowest frequency domain unit among the N SSBs (when N = 3, the index of the reference SSB is 0 (SSB #0);

[0233] ------- the SSB corresponding to the largest SSB index (N-1) or the highest frequency domain unit among the N SSBs (when N = 3, the index of the reference SSB is 2 (SSB #2);

[0234] ----- Optionally, when N is an even number (2, 4, 6, 8, 10...), taking N = 4 as an example, as shown in FIG. 6, SSB #0, SSB #1, SSB #2, SSB #3 are transmitted in the same time unit 0 and on different frequency domain units (SSB #0, SSB #1, SSB #2, and SSB #3 are transmitted on frequency domain units 0, 1, 2, and 3, respectively).

[0235] ------ the index of the reference SSB in frequency domain SSB pattern is a combination of one or more of:

[0236] ------- an index of (N / 2) or floor [(N+1) / 2] (when N = 4, the index of the reference SSB is 2 (SSB #2));

[0237] ------- an index of floor [(N-1) / 2] or (N-2) / 2 (when N = 4, the index of the reference SSB is 1 (SSB #1);

[0238] ------- the SSB corresponding to the smallest SSB index (0) or the lowest frequency domain unit among the N SSBs (when N = 4, the index of the reference SSB is 0 (SSB #0);

[0239] ------- the SSB corresponding to the largest SSB index (N-1) or the largest frequency domain unit among the N SSBs (when N = 4, the index of the reference SSB is 3 (SSB #3);

[0244] ------ As an example, FIG. 7 shows the frequency domain and time domain SSB pattern with where the indexing order of SSBs is increased in a way of frequency domain first and then time domain. For example, (time domain unit 0, frequency domain unit 0) corresponds to SSB index 0, (time domain unit 0, frequency domain unit 1) corresponds to SSB index 1, (time domain unit 0, frequency domain unit 2)) corresponds to SSB index 2, ..., (time domain unit 1, frequency domain unit 2) corresponds to SSB index 5;

Preferably, the corresponding frequency domain unit gap for a larger number of frequency division multiplexed SSBs Y (for example, Y is greater than or equal to, or not less than 8), may be greater than the frequency domain unit gap for a smaller value of Y. This has the advantage that when the number of frequency division multiplexed SSBs Y is large, the interference impact between beams corresponding to adjacent SSBs may be more severe, therefore, setting a larger frequency domain unit gap is beneficial to reducing the interference between adjacent SSBs and improving the signal quality on the beams.

[0276] --- In an implementation, the SSB pattern corresponds to one or more of the following different parameters: the number of SSBs N, the number of SSBs in time domain X, and the number of SSBs in frequency domain Y; according to embodiments of the present disclosure, the number of SSBs in frequency domain Y in an SSB pattern may be set to an integer greater than or equal to 2, and the value of Y may be set according to different operating frequencies of the system. For example, Y may be set to an even value such as 2, 4, 8, 16, 32, 64, etc., or Y may also be set to an odd value greater than 2; the total number of SSBs N in an SSB pattern may be set to an integer greater than or equal to 2, for example, set N to an even number above 2, or set N to an odd number greater than N; the number of time units X corresponding to the SSBs in an SSB pattern may be set to an integer greater than or equal to 1, and there may be the same or different gaps among the X time units in the SSB pattern, and the gap(s) may be predefined or configurable; or the X time units may be consecutive; the following examples list some possible SSB pattern related parameters:

[0280] --- In an implementation, in the second-type SSB pattern, the subcarrier spacings (SCSs) of all SSBs are the same, which may be where alternatively, the subcarrier spacings of SSBs may also be set to be different. For example, the second-type SSB pattern includes two time domain units, and the subcarrier spacing of Y frequency division multiplexed SSBs corresponding to the first time domain unit is the subcarrier spacing corresponding to the subcarrier spacing of Y frequency division multiplexed SSBs corresponding to the second time domain unit is the subcarrier spacing corresponding to

For example, the two first frequency locations are the second-type GSCN1 and the second-type GSCN2, respectively; in the present application, the GSCN used to determine the first type SSB pattern is called the first type GSCN, the GSCN used to determine the second-type SSB pattern is called the second-type GSCN, and the GSCN used to determine the pattern of RSs dedicated to beam management is called the third type GSCN. It should be understood that the GSCN described throughout the text may also be replaced by other names or terms that may be used to determine the frequency location of the downlink reference signal, such as reference location, reference frequency, etc., and the description with the GSCN is only for ease of description and understanding, and is not intended to limit the method of the present application to the described manners related to GSCN;

[0286] ------ In an implementation, the first type SSB may also be transmitted at the first frequency location, and the UE may determine whether the detected SSB is the first type SSB or the second-type SSB through the SSB type-related information included in the SSB; for example, when it is determined as the second-type SSB, the UE may consider that the second-type SSB (burst) is transmitted on the first frequency location; alternatively, the UE may use an indication of the second-type SSB (burst) to determine whether the second-type SSB (burst) is transmitted at the first frequency location;

For example, the information may indicate the index of the SSB pattern. U bits may indicate 2^U pattern indexes. For example, U = 3 bits may indicate 8 pattern indexes, for example, '001' indicates pattern index 1, '010' indicates pattern index 2, etc.; for example, SSB pattern index 1 is for an SSB pattern composed of SSBs transmitted on Y = N different frequency domain units in 1 time unit; SSB pattern index 2 is for an SSB pattern composed of SSBs transmitted in 2 time units and Y = N / 2 different frequency domain units, which is only an example, and the SSB pattern may also be other possibilities mentioned above, and will not be repeated; in addition, the pattern may be a pattern preset in the protocol, or a pattern configured through higher layer signaling;

[0310] ----- among them, in the same time unit, the generation sequences of the N RS signals or Y RS signals transmitted may be the same, or different sequences may be used (the benefit is that interference between adjacent beams may be reduced with different sequences by utilizing the orthogonality between them);

[0311] ---- resource configuration for RS dedicated to beam management, including one or more of:

[0312] ----- a time reference point, which may be used to determine the time domain start location of the RS or RS pattern.

The advantage is that the UE may determine whether RS burst dedicated to beam management is configured by detecting the SSB corresponding to the third type GSCN. For example, if the UE detects the first type SSB on the third type GSCN, the UE may consider that the RS burst dedicated to beam management is configured.

[0323] --- Optionally, the above-mentioned third type GSCN is used as a reference frequency point for detecting the first type SSB, and the reference frequency point may also be obtained according to the reference frequency information of the RS dedicated to beam management included in the configuration information for the RS dedicated to beam management.

[0343] ---- a frequency domain reference point and / or frequency domain unit offset, which may be used to determine the frequency domain start location of the gDRS, including the frequency domain start location determined based on the frequency domain unit offset or gap relative to a frequency domain reference point, the frequency domain reference point may be an absolute frequency domain reference point such as a specified point A or GSCN or ARFCN (with absolute frequency numeral value indication); and / or, a specified frequency point (the frequency domain start point of a bandwidth, a BWP, a carrier, an SSB, etc.); and / or, a frequency reference point of a related signal, such as a frequency location (e.g., a location of a center frequency point) of a reference signal used to activate the UE to receive SSB or wake up the UE; and / or, a frequency domain reference point of a related signal, such as the first or last frequency domain unit where the PBCH and / or PDCCH and / or PDSCH carrying the resource configuration for RS dedicated to beam management is received, or the first or last frequency domain unit of the PDCCH that schedules the PDSCH that carries the resource configuration for RS dedicated to beam management;

[0344] ---- a frequency offset or gap, indicating a frequency offset of the frequency domain start location of the gDRS to the frequency domain reference point, the frequency offset may be one or more frequency domain units or GSCNs or ARFCNs;

[0345] ---- a subcarrier spacing of the gDRS;

[0346] ---- indication of whether the gDRS supports frequency division multiplexing, which is used to indicate whether the base station has enabled the mode of transmitting a gDRS in frequency division multiplexing, that is, the UE identifies to determine the bandwidth of the received signal based on the frequency domain resources occupied by the frequency division multiplexed gDRSs during gDRS reception, and the determination method is as described above and will not be described again;

[0347] ---- configuration information of a measurement window, including the time domain start point, the time unit length in time domain, and the time domain period size, of the measurement window;

[0348] ---- a type of measured feedback value, comprising a combination of one or more of

[0349] ----- an index of the gDRS or an index of the corresponding frequency domain unit corresponding to it;

[0350] ----- a measured power value of the gDRS, e.g. a measured value of a reference signal in SSB (e.g. expressed as a SS-RSRP value);

[0351] ---- resource configuration information for measured feedback reporting, which includes at least one of: a periodicity of the resource for reporting, the start location and the number of occupied physical resource blocks of the frequency domain resource, the start location and the number of occupied time domain symbols of the time domain resource;

[0352] --- In an implementation, the UE determines whether to receive the gDRS according to a certain triggering condition, the gDRS is such as the second-type SSB or the RS dedicated to beam management, including a combination of one or more of:

[0353] ---- the UE receiving indication on whether the base station enables gDRS transmission. For example, in an implementation, the indication on whether the base station enables second-type SSB (or second-type SSB burst) transmission received by the UE may include at least one of:

[0354] ----- explicit indication, such as a 1-bit notification;

[0355] ------ UE may acquire it through PBCH and / or SIB1 PDCCH and / or SIB1 PDSCH;

[0356] ----- implicit indication, enabled if gURS resource corresponding to the gDRS (for example, PRACH resource or PUSCH or PUCCH resource used to report the measured quantity corresponding to the gDRS) is configured; not enabled if gURS resource corresponding to the gDRS is not configured;

[0357] --- In an implementation, when the gDRS is SSB, the condition for the UE to determine whether to receive the gDRS may also be determined based on a frequency offset (e.g., Kssb) indicating an offset between the SSB and a resource grid, where the resource blocks included in the resource grid are determined based on a common subcarrier spacing, e.g., the offset is greater than or not less than or equal to O1; alternatively, the offset is less than or not greater than or equal to O2; alternatively, when the offset is greater than or equal to O1 and less than or equal to O2, transmission of the second-type SSB is enabled by the base station; otherwise, it is not enabled, where O1 is not equal to O2, O1 and O2 are offset thresholds preset by the protocol, and O1 and O2 are integers;

[0358] --- In an implementation, when the gDRS is SSB, the UE may determine whether the received SSB is a first type SSB or a second-type SSB in at least one of the following ways:

[0359] ---- if the detected SSB includes configuration information related to the second-type SSB, then the detected SSB is the second-type SSB; otherwise, it is the first type SSB; in other words, based on whether the detected SSB includes configuration information related to the second-type SSB, it may be determined whether the detected SSB is a second-type SSB;

[0360] ---- determining based on information included in the detected first type SSB,for example, the first type SSB may include configuration information related to the second-type SSB, obtaining configuration information related to the second-type SSB based on the detected first type SSB, and receiving the second-type SSB based on the configuration information related to the second-type SSB; in other words, the configuration information related to the second-type SSB is included in the first type SSB, by receiving the first type SSB to obtain the configuration information related to the second-type SSB, the UE may be informed whether subsequently received SSB is a second-type SSB based on the configuration information related to the second-type SSB;

[0361] --- In an implementation, when the gDRS is SSB, the UE determines whether the base station enables transmission of the second-type SSB based on the detected SSB, which includes a combination of one or more of:

[0362] ---- determining whether the base station enables the second-type SSB based on indication of the second-type SSB (burst) obtained by receiving configuration information related to the second-type SSB. For example, when receiving the first type SSB, the UE obtains indication on the second-type SSB (burst) included in configuration information related to the second-type SSB through PBCH. For example, 1 represents that the base station enables the second-type SSB, 0 represents that the base station enables the first-type SSB; on the contrary, 0 means that the base station enables the second-type SSB, and 1 means that the base station enables the first-type SSB; alternatively, if the SSB received by the UE includes configuration information related to the second-type SSB, the UE may be informed that the base station enables the second-type SSB;

[0363] ---- determining whether the detected SSB is the first type SSB or the second-type SSB based on the SSB type related information obtained by receiving configuration information related to the second-type SSB.

[0364] ---- if the UE receives the configuration information related to the second-type SSB, the UE considers that the base station enables transmission of the second-type SSB;

[0365] --- In an implementation, the UE satisfies the status condition for receiving the gDRS burst when at least one of the following conditions is met, otherwise the UE does not satisfy;

[0366] ---- UE capability supports receiving a gDRS burst (frequency division multiplexed multiple gDRSs transmitted over a single time unit), where the gDRS burst refers to a burst of second-type SSBs and / or a burst of RSs dedicated to beam management; and / or

[0367] ---- UE capability supports receiving the frequency reference point mentioned above (for example, the first type GSCN and / or the second-type GSCN and / or the third type GSCN preset by the protocol); and / or

[0368] ---- the minimum channel bandwidth supported by the UE is larger or not smaller than the channel bandwidth occupied by the gDRS burst; and / or

[0369] ---- the minimum channel bandwidth supported by the UE is larger or not smaller than the channel bandwidth occupied by at least two frequency division multiplexed gDRSs (belonging to a gDRS burst); and / or

[0370] ---- the maximum number of frequency division multiplexed gDRSs supported by the UE is greater than or not less than two; and / or

[0371] ---- the maximum channel bandwidth supported by the UE is larger or not smaller than the channel bandwidth occupied by the frequency division multiplexed gDRSs; and / or

[0372] --- In an implementation, the UE enables reception of the gDRS burst when the UE receives the indication that the base station enables the gDRS burst and / or the UE satisfies a status condition to receive the gDRS burst;

[0373] --- It should be noted that in the present invention, the GSCN used to determine the first type SSB pattern is called the first type GSCN, and the GSCN used to determine the second-type SSB pattern is called the second-type GSCN;

[0374] --- In an implementation, the first type GSCNs may include the second-type GSCN, that is, the second-type GSCN may correspond to the first type SSB or the second-type SSB. For example, the range of first type GSCNs is from N1 to N2, where the second-type GSCN may be one or more GSCN values in the range. Multiple GSCN values may be continuous, such as N1, N1+1, N1+2,..., or discontinuous, such as N1, N1+3, N1+5 etc.; which has the benefit that the base station may configure the frequency domain locations of the first type SSBs more flexibly, and UEs that do not support the second-type SSB may also detect the first type SSB on the second-type GSCN, which reduces the detection complexity of the UEs and enhances the performance of random access;

[0375] --- The UE receives a gDRS burst, such as a second-type SSB burst, and the second-type SSB burst will be described below as an example of the gDRS burst received by the UE. The relevant method for the UE to receive the RS burst dedicated to beam management may be obtained similarly and will not be described again below. Wherein the method of determining the frequency location of the second-type SSB includes a combination of one or more of:

[0376] ---- In an implementation, the frequency location of the second-type SSB may be determined based on a first frequency location, the first frequency location is used to determine frequency location of the reference SSB (or called anchor SSB). In the second-type SSB burst, the frequency location of at least one SSB (or called reference SSB) among the frequency division multiplexed SSBs corresponding to one time domain unit, is at the first frequency location; the UE receives a second-type SSB burst based on the first frequency location, wherein the first frequency location may be frequency location of a reference SSB in the second-type SSB burst; the UE may obtain the first frequency location by receiving configuration information related to the second-type SSB, and the UE receives the second-type SSB burst based on the first frequency location, where the first frequency location may be the frequency location of the reference SSB in the second-type SSB burst, and the pattern of the second-type SSB may be related to the first frequency location;

[0377] ----- optionally, the first frequency location may be frequency location determined according to a Global Synchronization Channel Number (GSCN) or an ARFCN (Absolute Radio Frequency Channel Number), the GSCN or the ARFCN may be used to determine the frequency location of the SSB (e.g., reference frequency location of the SSB, or denoted SSREF). Specifically, the mapping relationship between synchronization raster and corresponding resource elements of the SSB may be that, the synchronization raster is mapped to location of the center frequency point of the SSB. For example, the SSB occupies 20 physical resource blocks (PRBs) in frequency domain, the corresponding resource element indexes (RE indexes) or subcarrier indexes are 0~239, then the location of the center frequency point of the SSB is the RE with index 120, that is, the reference frequency on the synchronization raster corresponds to the center of the first (1st) subcarrier on the 11-th PRB of the SSB. Optionally, the rules apply to uplink and downlink;

[0378] ------ As a possible embodiment, GSCN may be used to determine frequency location of the reference SSB in the frequency domain SSB burst. For example, the frequency location of the reference SSB in a frequency domain SSB burst is in a fixed frequency range, such as 3000MHz ~ 24250MHz, GSCN = 7500 corresponding to the frequency location of the reference SSB, then an R value may be determined based on the GSCN, such as GSCN = 7499+R, where the value of R is an integer greater than or equal to 0 (R is greater than or equal to zero, less than or equal to Rmax, where the value of Rmax is related to the above fixed frequency range). In the example of GSCN = 7500, the value of R is 1, then according to the formula: frequency location of the reference SSB in frequency domain SSB burst (SSREF) = 3000MHz+R* 1.44 MHz, the UE may determine the frequency location of the reference SSB in the frequency domain SSB burst (SSREF) = 3000MHz+1 * 1.44 MHz = 3001. 44MHz.

[0379] ---- In an implementation, the first frequency location may be determined by a combination of one or more of the following ways:

[0380] ----- the first frequency location preset by the protocol;

[0381] ----- the UE obtains the first frequency location by receiving configuration information related to the second-type SSB. For example, the configuration information related to the second-type SSB may include information about the first frequency location. In an implementation, the first frequency location obtained according to the configuration information related to the second-type SSB may be different from the first frequency location preset by the protocol, that is, the UE may be configured with a new first frequency location for determining frequency location of the reference SSB; in this way, when the UE does not support the first frequency location preset by the protocol, the first frequency location supported by the UE that is different from the protocol preset may be obtained through the configuration information; alternatively, the first frequency location obtained according to the configuration information related to the second-type SSB may replace the first frequency location preset by the protocol. In other words, the first frequency location is configured through the configuration information related to the second-type SSB without being preset by the protocol; alternatively, information related to the reference frequency point of the first type SSB (for example, the first type GSCN) may be preset through the protocol, and the frequency location information corresponding to the reference SSB for the second-type SSB (for example, the above-mentioned first frequency location, or the second-type GSCN) may be configured through configuration information related to the second-type SSB; alternatively, the information related to the reference frequency point of the first type SSB (for example, the first type GSCN) and the frequency location information corresponding to the reference SSB for the second-type SSB (for example, the above-mentioned first frequency location, or the second-type GSCN) may be preset through the protocol, and the frequency location information corresponding to the reference SSB for the second-type SSB that is different from the protocol preset value (for example, the above-mentioned first frequency location, or the second-type GSCN) may also be configured through the configuration information related to the second-type SSB;

[0382] ----- frequency location determined by the UE based on a specified frequency reference point and frequency offset is used as the first frequency location. In this way, the location of the reference SSB may be more flexible, facilitating the configuration of the base station and the implementation of the UE, where,

[0383] ------ the frequency reference point may be a specified point A or GSCN or ARFCN (with absolute frequency numeral value indication); and / or, a specified frequency point (the frequency domain start point, end point, middle point or other location of a bandwidth, a BWP, a carrier, an SSB, etc.); and / or, frequency location of a related signal is used as the frequency reference point, such as the frequency location of a reference signal used to activate the UE to receive SSB or wake up the UE (such as the location of the center frequency point, the location of the start or end frequency point, or other location, etc.);

[0384] ------ the frequency offset may be one or more frequency domain units or GSCNs or ARFCNs, and the offset may be preconfigured or obtained by receiving system information or configuration information;

[0385] ---- In an implementation, the method for the UE to determine the second-type SSB pattern may include a combination of one or more of:

[0386] ----- based on the information related to the pattern or format or configuration parameter of SSBs and / or configuration parameter information of the downlink reference signal in the second-type SSB burst obtained by receiving the configuration information related to SSB, the second-type SSB pattern may be determined;

[0387] ----- determining the second-type SSB pattern based on the subcarrier spacing and / or operating band of the SSB, where different operating bands may correspond to one or more subcarrier spacings of SSBs and / or different value ranges of GSCNs; for example, a certain operating band may correspond to a certain value range of GSCNs, and the value range of GSCNs may correspond to a corresponding second SSB pattern, or further, the value range of GSCNs corresponding to the operating band also corresponds to multiple subcarrier spacings, the value range of GSCNs may also correspond to different second-type SSB patterns according to different subcarrier spacings. For example, the UE may determine the value range of the second-type GSCNs in the operating band (which may correspond to one or more GSCNs) based on the operating band, and may obtain the corresponding second-type SSB pattern based on the determined value range of the second-type GSCNs. If one or more GSCNs within the determined value range of the second-type GSCNs correspond to multiple subcarrier spacings, the corresponding second-type SSB pattern may be obtained according to the subcarrier spacing supported by the UE. The value range of the second-type GSCNs may be preset in the protocol for the operating band, or may be configured through RRC higher layer signaling; the SSB patterns corresponding to the second-type GSCNs may be preset in the protocol or may be configured through RRC higher layer signaling; the second-type SSB patterns corresponding to different subcarrier spacings may be preset in the protocol or may be configured through RRC higher layer signaling;

[0388] ------ For example, within the value range of the second-type GSCNs, there are a variety of different subcarrier spacings preset by the protocol, and the different subcarrier spacings correspond to different second-type SSB patterns. For example, within the value range of the second-type GSCNs, there are two subcarrier spacings, such as 15kHz, 30kHz, the subcarrier spacing of 15kHz may correspond to the second-type SSB pattern 1, and the 30kHz corresponds to the second-type SSB pattern 2; for example, the pattern 1 and pattern 2 may correspond to different numbers of time domain units, which has the advantage that different subcarrier spacings may correspond to different lengths of the SSB burst in time, and the UE may select the appropriate second-type SSB burst to detect according to the subcarrier spacing it supports. For example, if the UE supports a larger subcarrier spacing, the UE may select the SSB burst corresponding to the subcarrier spacing to reduce the delay of receiving the second-type SSB burst;

[0389] ------ Optionally, the UE may consider that the second-type SSB burst is transmitted on the frequency corresponding to one or more second-type GSCN values in the value range of the second-type GSCNs, and the second-type SSB pattern may be determined based on the value range of the second-type GSCNs; optionally, in the same operating band, there may be multiple value ranges of second-type GSCNs, and different value ranges may correspond to different second-type SSB patterns. For example, there are two value ranges, value range N1 ~ N2, which corresponds to the second-type SSB pattern 1, and value range N3 ~ N4, which corresponds to the second-type SSB pattern 2; the benefit of this is that multiple different second-type SSB patterns may be configured in the same operating band, which improves the flexibility of system configuration. The UE may select to detect the second-type SSB burst in the corresponding value range of the second-type GSCNs according to its own capability, such as the maximum bandwidth supported. For example, the frequency-division multiplexed SSBs in the second-type SSB pattern 2 transmitted in the range of the second-type GSCNs N3~N4 occupy a larger bandwidth, and the frequency-division multiplexed SSBs in the second-type SSB pattern 1 transmitted in the range of the second-type GSCNs N1~N2 occupies a smaller bandwidth. If the UE may support a large bandwidth, the UE may choose to detect the second-type SSB burst in the range of the second-type GSCNs N3~N4. This may help the UE quickly obtain the measurement results of multiple SSBs and reduce the delay of UE measurement;

[0390] ------ Optionally, the first type GSCN includes the second-type GSCN. For example, the second-type GSCN may be a part selected from multiple values of the first type GSCNs; in this way, implementation may be simplified, signaling overhead may be less, changes to the protocol may be less, detection complexity of the UE may be reduced, and random access performance may be enhanced;

[0391] --- In an implementation, the UE receives a signal containing a second-type SSB, the SSB corresponding to one or more SSBs in the second SSB pattern mentioned above

[0392] ---- When the gDRS is SSB, the way in which the UE determines the frequency domain resource occupied by multiple SSBs in frequency domain may be a combination of one or more of:

[0393] ----- determined according to the number (Y) of frequency division multiplexed SSBs in one time unit, for example, the frequency domain resource occupied by multiple frequency division multiplexed SSBs is Btotal= Y BSSB, where BSSBis the frequency domain resource of a single SSB (the frequency domain unit occupied by an SSB in frequency domain, for example, 20 PRBs);

[0394] ----- determined according to the number (Y) of frequency division multiplexed SSBs in one time unit and the frequency gap G between frequency domain units occupied by the SSBs. For example, the frequency domain resource occupied by multiple frequency division multiplexed SSBs is Btotal= Y BSSB+G (Y-1), where BSSBis the frequency domain resource of a single SSB (the frequency domain unit occupied by an SSB in frequency domain, for example, 20 PRBs); among them, the frequency domain gap G may be configured as 0 or M frequency domain units (1 frequency domain unit such as 1 PRB), where the benefit of configuring the gap is that interference between adjacent beams may be reduced and the signal quality on beams may be improved;

[0395] --- The UE receives and measures the gDRS and obtains a measured feedback value, including one or more of:

[0396] ---- In an implementation, the UE receives and measures the gDRS in X time units and Y frequency domain units where the gDRS may exist;

[0397] ---- In an implementation, the measured feedback values include a combination of one or more of:

[0398] ----- indexes of gDRSs exceeding a power threshold or indexes of the corresponding frequency domain units; and / or

[0399] ----- an index of the gDRS corresponding to the largest measured power value or the index of the corresponding frequency domain unit;

[0400] ----- measured power values corresponding to gDRSs exceeding a power threshold, e.g., measured values of the reference signals in SSBs (e.g., expressed as SS-RSRP values);

[0401] ----- indexes of the gDRSs corresponding to the multiple largest measured power values or the indexes of the corresponding frequency domain units; this method is beneficial to beam management;

[0402] ----- indexes of gDRSs corresponding to multiple measured power values exceeding a power threshold or indexes of the corresponding frequency domain units; this method is beneficial to beam management;

[0403] ----- the above power threshold may be obtained through PBCH and / or SIB1 PDCCH and / or SIB1 PDSCH;

[0404] - The UE transmits uplink signals according to the received gDRSs, comprising one or more of the following operations:

[0405] -- the UE obtains configuration information related to SIB1 PDCCH and / or initial uplink / downlink frequency domain resource (e.g., BWP). Optionally, the configuration information may be obtained according to SSB;

[0406] --- In an implementation, the configuration information includes a combination of one or more of:

[0407] ---- configuration information related to SIB1 PDCCH, for determining or indicating a combination of one or more of:

[0408] ----- a multiplexing pattern;

[0409] ----- the number of (consecutive) frequency domain units occupied;

[0410] ----- the number of (consecutive) time domain units occupied;

[0411] ----- a frequency resource offset (which may be one or more frequency domain units) relative to the SSB, which may be a frequency offset relative to the lowest resource block of the detected SSB (or the first resource block of the SSB); and / or relative to the lowest resource block of the SSB (or the first resource block of the SSB) corresponding to the lowest frequency unit (e.g., the lowest indexed resource block) (e.g., the lowest indexed SSB) in the second-type frequency domain burst; and / or relative to the highest resource block of the SSB (or the last resource block of the SSB) corresponding to the highest frequency unit (e.g., the highest indexed resource block) (or the highest indexed SSB) in the second-type frequency domain burst; and / or relative to the frequency of the reference SSB (the first frequency location described above) in the second-type frequency domain burst or the lowest or highest or middle resource block of the reference SSB, where the middle resource block refers to the resource block indexed N / 2 or N / 2-1, where N is the number of resource blocks occupied by the SSB, which has the benefit of reducing the number of bits required to indicate the frequency offset;

[0412] ---- configuration information related to SIB1 PDCCH monitoring occasion, where the configuration information is used to determine or indicate a combination of one or more of: a time domain offset (which may be one or more time units) relative to the start location of the system frame, the number of search space sets in each frequency domain unit, and the start symbol of the time unit containing a search space set;

[0413] ---- initial downlink and / or uplink frequency domain resource (e.g., BWP) and / or configuration information related to the minimum channel, including configuration information related to frequency domain resource, including bandwidth size; and / or frequency domain start point and the number of resource blocks occupied;

[0414] ----- preferably, the initial downlink BWP may be used for the UE to monitor the SIB1 PDCCH, and the SIB1 PDCCH is used to schedule the SIB1 PDSCH; optionally, the frequency domain resource occupied by the SIB1 PDCCH is less than or equal to or not greater than the frequency domain resource of the initial downlink BWP (in other words, the frequency domain resource occupied by the SIB1 PDCCH is included in or equal to the initial downlink BWP); optionally, the initial downlink BWP may also be used by the UE to receive msg2 (RAR) and / or msg4;

[0415] ----- preferably, the initial uplink BWP may be used by the UE to transmit a preamble (for example, transmitted on PRACH) and / or msg3 for random access;

[0416] ----- In an implementation, the configuration information related to the minimum channel may be determined by a combination of one or more of the following methods:

[0417] ------ explicit indication, for example, informed through 2 bits, '00' represents 10MHz, '01' represents 20MHz, '10' represents 50MHz, and '11' represents 100MHz. More bandwidth sizes may be indicated through more bits, which is not limited to only through 2 bits herein; preferably, the explicit indication may indicate different bandwidth sizes according to different band ranges. For example, in the case of FR2, 2 bits may indicate that '00' represents 50MHz, '01' represents 100MHz, '10' represents 200MHz, and '11' represents 400MHz;

[0418] -- The method for the UE to determine the configuration related to initial downlink and / or uplink frequency domain resource (for example, frequency domain resource of a BWP) may also include a combination of one or more of:

[0419] --- In an implementation, the resource of the initial downlink and / or uplink BWP is determined based on the frequency domain resource occupied by the detected SSBs in the frequency domain SSB burst; for example, one SSB in frequency domain SSB burst is detected, and the frequency domain resource it occupies is used as the initial downlink and / or uplink BWP;

[0420] --- In an implementation, it is determined by the frequency domain resource occupied by the detected SSB in frequency domain SSB burst and a third frequency offset, and the third frequency offset may be relative to: the lowest resource block of the SSB; and / or relative to the highest resource block of the SSB; and / or relative to the lowest or highest or middle resource block of the reference SSB in the frequency domain SSB burst, wherein the middle resource block refers to the resource block indexed N / 2 or N / 2-1, where N is the number of resource blocks occupied by the SSB;

[0421] --- In an implementation, the resource of the initial downlink and / or uplink BWP is determined by the frequency domain resource occupied by the SSBs configured in the frequency domain SSB burst pattern; for example, the frequency domain resource occupied by the SSBs configured in the frequency domain SSB burst pattern is used as the initial downlink and / or uplink BWP; in an example implementation, the frequency domain SSB burst may include all SSBs included in the second-type SSB pattern;

[0422] --- In an implementation, the location of the initial downlink and / or uplink BWP, such as the start location, center location, end location, etc., is determined through the frequency domain resource occupied by the SSBs configured in the frequency domain SSB burst pattern and a frequency offset, the frequency offset may be relative to: the lowest resource block of the SSBs configured in the frequency domain SSB burst pattern; and / or the highest resource block of the SSBs configured in the frequency domain SSB burst pattern; and / or, relative to the lowest or highest or middle resource block of the reference SSB in the frequency domain SSB burst pattern, where the middle resource block refers to the resource block indexed N / 2 or N / 2-1, where N is the number of resource blocks occupied by the SSB;

[0423] --- In an implementation, the frequency domain resource of the initial downlink and / or uplink BWP may include the frequency domain resource occupied by Z SSBs adjacent in frequency domain among Y frequency division multiplexed SSBs in the SSB burst pattern, where Z is less than or equal to or not greater than Y; for example, taking the reference SSB among Y frequency division multiplexed SSBs as the center, selecting Z consecutive SSBs including the reference SSB, and using the frequency domain resource occupied by the Z consecutive SSBs as the frequency domain resource of the initial downlink and / or uplink BWP; and / or, determine the frequency domain resource of the initial downlink and / or uplink BWP based on the index of the start SSB and the number of SSBs (for example, configured number information). For example, the index of the SSB is 0 and the number of SSBs is 3, then the frequency domain resource of the initial downlink and / or uplink BWP correspond to the frequency domain resource occupied by SSBs corresponding to SSB indexes 0, 1, and 2; among them, the above mentioned Z, as well as the index of the start SSB and the number of SSBs may be obtained by the UE according to the above configuration information related to the SIB1 PDCCH and / or the initial uplink / downlink BWP;

[0424] ---- it should be noted that the benefit of configuring the bandwidth of the initial downlink / uplink BWP to be smaller than the frequency domain resource occupied by Y frequency division multiplexed SSBs is that it may help reduce the complexity of blind detection of DCI by the UE;

[0425] ---- the initial uplink / downlink frequency domain resource determined by the UE may be used for initial access, and also for other communication between the UE and the base station, such as data communication. Determining the initial uplink / downlink frequency domain resource in the above manner enables the UE to directly use that frequency domain resource for communication with the network device;

[0426] --- In an implementation, among the Y frequency division multiplexed SSBs, each SSB (for example, the SSB index is y, where y = 0, 1, 2..., Y-1) may correspond to an initial uplink and / or downlink BWP (for example, the index of the occupied frequency domain unit of the initial uplink and / or downlink BWP corresponding to SSB index y is y);

[0427] ---- wherein, the frequency domain resource occupied by the initial downlink and / or uplink BWP may be completely overlapping and / or partially overlapping with the frequency domain resource of the corresponding frequency domain SSB and / or non-overlapping with the frequency domain resource of the corresponding frequency domain SSB but with a frequency domain gap not exceeding one frequency domain unit or predetermined multiple frequency domain units and / or non-overlapping with the frequency domain resource of the corresponding frequency domain SSB but with a frequency domain gap of zero;

[0428] --- Preferably, the bandwidth of the initial downlink and / or uplink BWP is less than or equal to or not greater than the maximum channel bandwidth supported by the UE;

[0429] -- In an implementation, Y frequency division multiplexed SSBs may also correspond to less than or equal to or no more than Y carriers, wherein each carrier may include at least one frequency division multiplexed SSB, and the initial downlink / uplink BWP corresponding to each carrier may be determined based on the frequency domain resource of the frequency division multiplexed SSB and / or the above-mentioned initial downlink and / or uplink BWP and / or configuration information related to the minimum channel bandwidth;

[0430] -- In an implementation, the frequency domain SSB is associated with the initial downlink and / or uplink BWP, and the association may be a combination of one or more of:

[0431] --- one-to-one association, such as one frequency domain SSB is associated with one initial downlink and / or uplink BWP one-to-one, such as a one-to-one association through the index of the frequency domain SSB and the index of the initial downlink and / or uplink BWP, for example, the SSB with index 0 is associated to the BWP with index 0; and / or,

[0432] --- multiple-to-one association, that is, multiple frequency domain SSBs are associated to one initial downlink and / or uplink BWP, for example, a multiple-to-one association through the indexes of the SSBs and the index of the initial downlink and / or uplink BWP, for example, SSBs with index 0, 1, 2, 3 are associated to the BWP with index 0;

[0433] ---- The benefit of the above association is that, in case that the UE performs initial access through an SSB in the frequency domain SSB burst, the UE may quickly determine the appropriate initial uplink and / or downlink BWP corresponding to different frequency domain resource based on its corresponding SSB index, which is beneficial to reduce conflict during resource allocation and / or random access, and improve resource utilization and efficiency of resource scheduling by the base station; for example, the UE may transmit a preamble for random access based on the selected SSB and the initial uplink BWP associated with the SSB; alternatively, the UE may also monitor the PDCCH for RAR or msg4, and / or receive the PDSCH for RAR and msg4, based on the selected SSB and the initial downlink BWP associated with the SSB;

[0434] --- In an implementation, when the SSB and the downlink and / or uplink BWP are in multiple-to-one association, the frequency domain resource occupied by the downlink and / or uplink BWP may include the frequency domain resource occupied by the multiple associated SSBs;

[0435] -- In an implementation, the second-type SSB and the initial downlink and / or uplink BWP are associated in time domain.

[0436] --- In an implementation, the time domain location of the downlink and / or uplink initial BWP may be determined based on the time domain location of its associated SSB and a time domain offset, and the time domain offset may be a time domain offset preset by the protocol, such as single or multiple time domain units; or obtained based on the above configuration information related to SIB1 PDCCH and / or initial downlink / uplink BWP; or,

[0437] --- In an implementation, the time domain location of the downlink and / or uplink initial BWP may also be the same as the time domain location of its associated SSB, for example, at the same time domain location within a specific time period. For example, the second-type SSB pattern involves X=2, Y=4, N=X multiplied by Y=8, time unit 1 corresponds to Y=4 frequency division multiplexed SSBs, with the SSB indexes being 0, 1, 2, 3 sequentially from the lowest to the highest frequency domain unit; time unit 2 corresponds to Y = 4 frequency division multiplexed SSBs, with the SSB indexes being 4, 5, 6, and 7 sequentially from the lowest to the highest frequency domain unit; then the time domain location of the initial downlink and / or uplink BWP bound to SSBs 0, 1, 2, and 3 corresponding to time unit 1 may be determined based on time unit 1, for example, the start location is the same as the time domain location of the start location of time unit 1 in a specific time period or determined based on the start location of time unit 1 and the above time offset; in the same way, the time domain location of the initial downlink and / or uplink BWP bound to SSBs 4, 5, 6, 7 corresponding to time unit 2 may be determined based on the time unit 2, for example, the start location is the same as the time domain location of the start location of the time unit 2 in a specific time period or determined based on the start location of the time unit 2 and the above time offset.

[0438] -- In an implementation, the UE determines whether there is PDCCH resource configuration (such as CORESET of Type0 PDCCH CSS set) or whether the cell provides SIB1 based on the detected frequency division multiplexed SSB (such as based on the MIB information in the SSB); optionally, it determines according to the value of the subcarrier offset of the SSB included in the MIB;

[0439] -- The UE determines a second frequency reference point based on the received second-type SSB, and the second frequency reference point may be used to determine a common reference point of the resource block grid and to determine the frequency domain start point and / or bandwidth size of a carrier or BWP; the operations comprising one or more of:

[0440] --- In an implementation, the UE determines the location of the second frequency reference point based on the frequency location where an SSB is detected, the SSB may be the SSB with the largest measured power value of the reference signal (e.g., SS-RSRP) among Y frequency division multiplexed SSBs in the same time unit; and / or, may be any one of the SSBs in Y frequency division multiplexed SSBs whose measured power value of the reference signal exceeds a power threshold;

[0441] --- In an implementation, the second frequency reference point may also be a specified point A or GSCN or ARFCN (with absolute frequency numeral value indication) or a specified frequency point (a frequency domain start point of a bandwidth, a BWP, a carrier, etc.), or may be a frequency domain reference point of a related signal, such as the first or last frequency domain unit where the PBCH and / or PDCCH and / or PDSCH carrying resource configuration of the SSB is received, or the PDCCH scheduling the PDSCH carrying the resource configuration of the SSB is received;

[0442] --- In an implementation, the UE determines downlink and / or uplink frequency domain resource (such as a carrier, a BWP, etc.) through the second frequency reference point and a second frequency offset: optionally, the second frequency offset may be obtained through PBCH and / or SIB1 PDCCH and / or SIB1 PDSCH;

[0443] --- In an implementation, the second frequency offset (in unit of one or more frequency domain units) may be a frequency offset (e.g., referred to as frequency-offset1 or Ncrb) between the second frequency reference point and the lowest subcarrier of a lowest resource block (e.g., a common resource block (CRB)), the lowest resource block is a resource block that overlaps with the lowest resource block in the second-type SSB burst (or the first resource block or the resource block corresponding to the minimum resource block index of the second-type SSB burst). FIG. 11 gives an example, where the second-type SSB burst includes Y frequency division multiplexed SSBs, and the second frequency offset represents a gap of one or more frequency domain units between the second frequency reference point (for example, the center frequency of the start subcarrier (subcarrier 0) of CRB0 is used as the frequency reference point) and the lowest resource block, wherein the lowest resource block is a resource block that overlaps with the lowest resource block (or the resource block corresponding to the smallest resource block index) (in the illustrated example, the lowest resource block of SSB #0) of the frequency domain SSB burst (CRB Ncrb in FIG. 11). The SSB pattern in frequency domain (second-type SSB pattern) in FIG. 11 is only an example, and may also be other SSB patterns mentioned above, which will not be described again here;

[0444] --- In an implementation, the location of the second frequency reference point may be determined based on a frequency gap between the frequency corresponding to the detected SSB and the lowest frequency (unit) in the first mode corresponding to the SSB, and a frequency gap between the lowest frequency (unit) of the second burst and the second frequency reference point;

[0445] --- In an implementation, the frequency gap between the frequency corresponding to the detected SSB and the lowest frequency (unit) of the second burst corresponding to the SSB may be determined by the index of the SSB and the second pattern to which the SSB belongs. For example, the index of the detected SSB is y, and its corresponding frequency may be determined according to the second pattern as wherein may be determined based on the index of the reference SSB in the second burst (corresponding to the first frequency location), and a frequency offset of the detected SSB from the reference SSB in the second burst, and the frequency offset may be determined based on an index offset of the detected SSB from the reference SSB in the second burst, and the frequency domain gap between adjacent SSBs;

[0446] --- In an implementation, the frequency domain gap between SSBs adjacent in frequency domain may be the number of frequency domain units (such as RBs) occupied by an SSB, a frequency gap between the center frequency points of SSBs adjacent in frequency domain;

[0447] --- In an implementation, the frequency gap between the lowest frequency (unit) of the second burst and the second frequency reference point may be determined based on the configuration of RRC higher layer signaling;

[0448] --- As an example, the location of the second frequency reference point wherein and may be subcarrier spacings specified by the protocol (for example, determined according to the type of SSB or frequency band range) or determined according to higher layer parameters. SCS1 may be determined according to a configured parameter, and SCS2 may be the subcarrier spacing of CRB, is the subcarrier spacing of the SSB, where y = 0, 1, 2..., Y-1 is the index or frequency domain unit index corresponding to the detected SSB, where 12 is the number of subcarriers occupied by a resource block, 12 is only for example, it may be other values;

[0449] --- In an implementation, the location of the second frequency reference point may be determined according to a combination of one or more of: the index or frequency domain unit index corresponding to the detected SSB, the number of occupied RBs of the SSB, the subcarrier spacing of the SSB, the frequency location of the 0th subcarrier in the lowest resource block of the detected SSB #0, frequency-offset1 (i.e., the above-mentioned second frequency offset) and frequency offset 2 (as shown in FIG. 11), wherein frequency offset 2 (written as kssb) may be used to indicate an offset between subcarrier 0 of the lowest resource block of the frequency domain SSB burst and subcarrier 0 of the common resource block overlapping with the lowest resource block (or the frequency offset between the lowest resource block of the SSB and the entire resource block grid, in unit of one or more frequency domain units), the frequency offsets 1 and 2 may be obtained through PBCH and / or SIB1. For example, in case that the index or the frequency domain unit index of the frequency division multiplexed SSB corresponding to a time domain unit detected by the UE is y, where y = 0, 1, 2..., Y-1, the UE may determine the location of the second frequency reference point based on the frequency location of the detected SSB and the second frequency offset. For example, the location of the second frequency reference point may be determined based on frequency-offset1, frequency offset 2, the index of the detected SSB (or other parameters that may be used to determine the gap between the frequency location of the detected SSB and the lowest frequency location in the second-type SSB burst). As shown in FIG. 11, the location of the second frequency reference point wherein and may be subcarrier spacings specified by the protocol (for example, determined according to the type of the SSB or frequency band range) or determined according to higher layer parameters. SCS1 may be determined according to a configured parameter, and SCS2 may be the subcarrier spacing of CRB, is the subcarrier spacing of the SSB, where y = 0, 1, 2..., Y-1 is the index or frequency domain unit index corresponding to the detected SSB, where 12 is the number of subcarriers occupied by a resource block, 12 is only for example, it may be other values;

[0450] ---- Optionally, in addition to the above-mentioned parameters, the location of the second frequency reference point may also be determined taking into account the guard gap G existing between adjacent SSBs, and the unit of the guard gap G may be one or more frequency domain units, the location of the second frequency reference point

[0451] --- In an implementation, the second frequency offset may also be the offset between the second frequency reference point and the resource block(s) corresponding to at least one frequency division multiplexed SSB, or referred to as the offset(s) between the second frequency reference point and the lowest subcarrier(s) of one or more lowest resource blocks (such as a common resource block (CRB)), the resource block or the lowest resource block corresponding to an SSB is the resource block overlapping with the lowest resource block (or the first resource block or the resource block corresponding to the minimum resource block index of the SSB) of the SSB corresponding to the index y or the frequency unit index y, where y = 0, 1, 2..., Y-1, corresponding to Y different frequency division multiplexed SSBs; there may be different second frequency offsets for different SSBs, such as frequency-offset1y, where y = 0, 1, 2..., Y-1 corresponds to Y different frequency division multiplexed SSBs. FIG. 12 gives an example, in which the second-type SSB burst includes Y frequency division multiplexed SSBs, and the second frequency offsets corresponding to the Y frequency division multiplexed SSBs may include multiple different values, for example, include Y different frequency-offset1, that is, frequency offset10, that is, frequency offset11, ..., that is, frequency offset1Y-1. The second frequency offset may be obtained through PBCH and / or SIB1 PDCCH and / or SIB1 PDSCH. The frequency domain SSB pattern (second-type SSB pattern) in FIG. 12 is only an example, and may also be other SSB patterns mentioned above, which will not be described again here; for the method of determining the frequency reference point based on the frequency offset, the description above may be referred to, and will not be described again here.

[0452] -- The UE obtains configuration information related to random access, including a combination of at least one or more of:

[0453] --- a configuration index for random access, to indicate a combination of one or more of: a random access preamble format, a random access configuration period, the number and location of random access frames in the random access configuration period, indexes of subframes or slots in a random access frame, start symbol location of the random access preamble in a subframe or slot, the number of random access slots in a random access subframe, the number of ROs in a random access slot, the number of OFDM symbols occupied in an RO;

[0454] --- mapping ratio of second-type SSB to RO for random access, the mapping ratio being used to determine the number of SSBs mapped on each RO, for example, when the mapping ratio is 1, it means that the RO and SSB are mapped (or associated) 1 to 1; when the mapping ratio is 1 / 4, 1 SSB may be mapped to 4 ROs; when the mapping ratio is 4, 4 SSBs are mapped to 1 RO;

[0455] ---- In an implementation, the mapping ratio may be a mapping ratio for a single SSB, and the ratios of SSB to RO corresponding to SSBs with different indexes or different frequency domain units may be the same or different. For example, SSB #1 may be mapped to 2 ROs, SSB #2 may be mapped to 4 ROs, and SSB #3 may be mapped to 2 ROs;

[0456] ---- In an implementation, the mapping ratio may be a mapping ratio for a group of frequency domain SSBs, where a group of frequency domain SSBs may include multiple SSBs with different indexes or SSBs corresponding to different frequency domain unit indexes. Optionally, the group of SSBs may be multiple SSBs adjacent in frequency domain. For example, a first group of SSBs includes SSBs with indexes {0, 1, 2, 3}, and a mapping ratio of SSB to RO corresponding to the group of SSBs is 1 to 2, i.e., 1 SSB is mapped onto 2 ROs, and a second group of SSBs includes SSBs with indexes {4, 5, 6, 7}, and a mapping ratio of SSB to RO corresponding to the group of SSBs is 1 to 4, i.e., 1 SSB is mapped onto 4 ROs; the benefit of such non-uniform mapping ratios of SSB to RO is that by allocating non-uniform ROs to each SSB, some unused PRACH occasions may be increased, allowing the base station to have opportunity to enter sleep mode and save energy consumption;

[0457] --- random access related period, including a combination of one or more of: a random access configuration period, an SSB-RO mapping cycle, an SSB-RO association period, an SSB-RO association pattern period;

[0458] --- the number of frequency domain ROs for random access;

[0459] --- frequency domain start location of the ROs for random access; for example, the frequency domain start location of the first RO, other frequency domain ROs are derived based on the location of the first RO and the size of the frequency domain resource occupied by an RO, and / or the frequency domain gap between ROs;

[0460] --- a random access preamble root sequence index for random access;

[0461] --- the number of random access preambles for random access, for example, the number of preambles for random access per RO;

[0462] --- power related configuration for random access, including at least one of:

[0463] ---- preamble target received power for random access, path loss compensation factor alpha for random access, such as alpha Х path loss, when alpha is less than 1, it indicates partial path loss compensation; alpha = 1, indicating full path loss compensation; alpha > 1, indicating excess path loss compensation. Such scenario is beneficial for the UE to have power increase additionally when transmitting the preamble on the RO associated with the second-type SSB in case that the normal preamble target received power is used. In an implementation, the condition for the UE to perform excess path loss compensation may be determined based on the index of the frequency division multiplexed SSB or the corresponding frequency domain unit index. For example, 4 frequency division multiplexed SSBs, in order of frequency unit index from low to high, the SSB indexes are 0, 1, 2, and 3 respectively, then alpha corresponding to SSB 0 and / or SSB 3 is alpha > 1. The benefit of this is to compensate the power of the SSB corresponding to the low frequency domain index (such as SSB 0) or high frequency domain index (such as SSB3) so that it is the same as the power of the SSB corresponding to the medium frequency domain index, such as SSB1, 2, ensuring that the frequency division multiplexed SSBs have the same coverage;

[0464] ---- a power increase delta value for random access, a power ramping priority and / or step for random access, etc.; the transmit power P is determined based on one or more of the target received power P0, alpha Х path loss, delta, power ramping stepХ the number of retransmissions;

[0465] ---- information related to the transmission power of frequency division multiplexed SSBs,

[0466] ----- In an implementation, the information includes information for determining the corresponding transmission powers Py, y = 0, 1, ..., Y-1 in case that Y frequency division multiplexed SSBs are transmitted, where the transmission powers of Y SSBs may be different, and the UE may calculate the power required for transmitting the preamble based on the information related to the transmission power of the frequency division multiplexed SSBs.

[0467] ----- In an implementation, the information includes the transmit power of the reference SSB of the frequency division multiplexed SSBs and the power offsets of other frequency division multiplexed SSBs relative to that of the reference SSB, and the UE may determine the corresponding transmit power Py, y = 0, 1, ..., Y-1 for transmitting Y frequency division multiplexed SSBs, based on the transmit power of the reference SSB and the power offset O. The advantageous effect is: the base station may flexibly configure the power corresponding to the frequency division multiplexed SSB to ensure that the coverage required in different directions is met;

[0468] --- indication information of transmission of the second-type SSB, which may be a combination of one or more of:

[0469] ---- In an implementation, the information indicates the frequency domain location of the transmitted SSB in frequency domain resource corresponding to the second-type SSB burst, which may be indicated using a bitmap, for example, the first / leftmost bit in the bitmap corresponds to SSB index 0 or the SSB corresponding to the lowest frequency domain unit in the second-type SSB burst, the second bit corresponds to SSB index 1 or the SSB corresponding to the second lowest frequency domain unit in the second-type SSB burst, and so on. A value of 0 in the bitmap indicates that the corresponding SSB is not transmitted, and a value of 1 indicates that the corresponding SSB is transmitted;

[0470] ---- In an implementation, the information indicates the time domain and frequency domain location of the transmitted SSB in frequency domain resource and time domain resource corresponding to the second-type SSB burst. Bitmap 1 may be used to indicate the time domain location. Bitmap 2 is used to indicate the frequency domain location. For example, the first / leftmost bit in bitmap 1 corresponds to the SSB corresponding to the lowest time domain unit in the second-type SSB burst; the second / leftmost bit in bitmap 2 corresponds to the SSB corresponding to the lowest frequency domain unit in the second-type SSB burst;

[0471] -- The UE selects the SSB, and the SSB is included in the second-type SSB burst. Specifically, the method for the UE to select the SSB may be:

[0472] --- In an implementation, if at least one SSB with a measured power value of the reference signal, such as SS-RSRP, higher than a power threshold is available, select the SSB with a measured power value higher than the power threshold; otherwise, select any SSB, where the power threshold may be obtained through SIB1 message;

[0473] --- In an implementation, if at least one SSB with a measured power value of the reference signal, such as SS-RSRP, above a power threshold is available, randomly select one of the multiple SSBs each with a measured power value above the power threshold, or select the one with the highest measured power value among the multiple SSBs each with a measured power value above the power threshold; otherwise, select any SSB, where the power threshold may be obtained through SIB1 message;

[0474] -- The UE selects the random access resource associated with the SSB according to the selected SSB;

[0475] --- In an implementation, considering that SSBs corresponding to different frequency domain units may correspond to different initial uplink / downlink BWPs, the UE may select the RO on the initial uplink BWP associated with the SSB,

[0476] --- In an implementation, in case that the SSB and the initial uplink BWP are in one-to-one association, the ROs included in the initial uplink BWP are only associated with the SSB (index);

[0477] --- In an implementation, in case that the SSB and the initial uplink BWP are in multiple-to-one association, the ROs included in the initial uplink BWP are associated with the multiple SSBs (indexes) associated with the initial uplink BWP;

[0478] -- performing gURS transmission according to the obtained measured feedback value

[0479] --- In an implementation, when the gURS is transmitted based on sequence, taking PRACH as an example, PRACH resource (including PRACH time-frequency resource, PRACH occasions or RACH occasions (ROs), or PRACH sequences) may be grouped, each group corresponds to one measured feedback value or a group of measured feedback values, the UE determines the corresponding PRACH resource group based on the obtained measured feedback value, and selects or determines the PRACH resource from the obtained PRACH resource group for PRACH transmission;

[0480] --- In an implementation, when the gURS is transmitted based on data, such as PUCCH and / or PUSCH, the UE transmits the obtained measured feedback value to the network device using the corresponding PUCCH and / or PUSCH resource; wherein,

[0481] ---- resource for the corresponding PUCCH and / or PUSCH (including time-frequency resource, and / or DMRS resource) may be pre-configured, or obtained by the UE through the configuration information from the network device;

[0482] ---- optionally, the PUSCH may be an msg3 PUSCH,

[0483] ---- optionally, the PUCCH may be the PUCCH after the msg4

[0484] ---- optionally, the measured feedback value may be transmitted via UCI on PUSCH;

[0485] ---- optionally, the measured feedback value may be carried through MAC CE;

[0486] -- In an implementation, when the UE receives an indication that the base station enables second-type SSB (or second-type SSB burst) transmission and / or the UE meets the status condition for receiving second-type SSB and / or the UE detects second-type SSB, the UE enables the gURS resource corresponding to the second-type SSB, wherein, it specifically includes a combination of one or more of:

[0487] --- determining resource for transmitting the gURS, wherein, it includes one or more of:

[0488] ---- In an implementation, when there is dedicated gURS resource allocated for the second-type SSB, and when the UE receives an indication that the base station enables the second-type SSB transmission and / or the UE meets the status condition for using DBF, the UE selects gURS resource from the gURS resource dedicated to the second-type SSB transmission being enabled for transmission;

[0489] ---- In an implementation, when there are multiple gURS resource available, randomly selecting one for transmission with equal probability;

[0493] ---- In an implementation, if the SSB associated with the selected gURS resource corresponds to a low or high frequency domain index, for example, the frequency domain index k corresponding to the SSB is less than or less than or equal to k1, or the frequency domain index k corresponding to the SSB is greater than or greater than or equal to k2, the k1 and k2 may be preset by the protocol or configured through higher layer signaling, then the UE uses power P2 to transmit the gURS signal, where P2 = P1+P_delta, the P_delta is a power difference that is preset or configured by the network, specifically, P_delta is determined according to whether reception of frequency domain SSB burst (second-type SSB burst) is supported;

[0494] ---- The advantageous effect of the above design is that, considering that the power of the SSB corresponding to the low or high frequency domain index is lower than the transmit power of the SSB corresponding to the medium frequency domain index (k is greater than or equal to k1, and k is less than or equal to k2), the UE may use P_delta to compensate for the power difference to ensure the coverage of the uplink signal; and / or,
