Description

COMMUNICATION METHOD, USER EQUIPMENT AND BASE STATION

[0001] The present disclosure relates to the technical field of wireless communication, and in particular to a communication method, a user equipment (UE) and a base station.

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

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

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

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

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

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

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.

[0144] 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.

[0145] 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.

[0146] 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.

[0147] 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.

[0148] 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.).

[0149] 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.

[0150] 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.

[0151] 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.

[0152] 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).

[0153] 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.

[0154] 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.

[0155] 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.

[0156] 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).

[0157] 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.

[0158] 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.

[0159] 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. The gNB 102 also includes a controller / processor 378, a memory 380, and a backhaul or network interface 382.

[0160] 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.

[0161] 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 by antennas 370a-370n.

[0162] 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.

[0163] 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.

[0164] 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.

[0165] 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.

[0166] 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.

[0167] 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).

[0168] In order to meet an increasing demand for wireless data communication services since a deployment of 4G communication system, efforts have been made to develop an improved 5G or pre-5G communication system. Therefore, the 5G or pre-5G communication system is also called "beyond 4G network" or "post LTE system".

[0169] 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.

[0170] 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.

[0171] 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.

[0172] In the communication system, the measurement and reporting of the UE is an important process in the communication between the base station and the UE, and how to reduce the measurement reporting delay is a direction continuously studied in the field.

[0173] Exemplary embodiments of the present disclosure are further described below with reference to the accompanying drawings.

[0174] The text and drawings are provided as examples only to help readers understand the present disclosure. They are not intended and should not be interpreted as limiting the scope of the present disclosure in any way. Although certain embodiments and examples have been provided, based on the disclosure herein, it will be apparent to those skilled in the art that changes may be made to the illustrated embodiments and examples without departing from the scope of the present disclosure.

[0175] An embodiment of the present disclosure provides a method executed by a UE in a communication system. As shown in FIG. 4, the method includes the following.

[0176] In step S101, a first message transmitted by a base station is received, the first message including that channel state information-reference signals (CSI-RSs) configured by the base station are QCLed with associated synchronization signal blocks (SSBs) and / or transmitting beams of at least two SSBs configured by the base station are fully or partially overlapped.

[0177] In step S102, after first measurement is triggered, a first measurement result is transmitted to the base station within a first delay, wherein the first delay is less than a second delay, and the second delay is a measurement reporting delay corresponding to a situation where the first message is not received.

[0178] For example, CSI-RSs configured by the base station (gNB) being QCLed with associated SSBs means that the quasi co-location information (QCL) of CSI-RSs configured by the gNB and associated SSB configuration resources is the indication of type D (TypeD). The QCL TypeD means that the parameters in spatial reception are consistent, for example, but not limited to, the angle of arrival or average angle of arrival of receiving beams being consistent.

[0179] For example, transmitting beams of at least two SSBs configured by the gNB being fully or partially overlapped means that SSB1 and SSB2 configured by the gNB are fully or partially overlapped in transmitting beams, but not limited thereto.

[0180] Optionally, the base station may transmit the above two pieces of information through one first message or multiple first messages. It will not be limited in the embodiment of the present disclosure.

[0181] In the embodiment of the present disclosure, the UE may reduce the measurement reporting delay of the UE according to the first message transmitted by the gNB. That is, after first measurement is triggered, a first measurement result is transmitted to the base station within a first delay that is less than a second delay. Since the measurement reporting delay is reduced, the UE can report the first measurement result more quickly. For the gNB's behaviors based on the first measurement result, such as handover, the handover process of the gNB can be completed more quickly. Accordingly, the reliability and efficiency of mobility are improved, and the performance of mobility is better ensured.

[0182] As an example, when the UE is moving and the UE satisfies a cell handover condition, a shorter measurement reporting delay can make the UE complete the whole handover process more quickly, and it is ensured that the UE handovers to a more suitable cell within a shorter time.

[0183] In the embodiment of the present disclosure, if the first message includes that CSI-RSs configured by the base station are QCLed with associated SSBs, the first measurement includes layer 3 measurement based on the CSI-RS resources, for example, which may include, but not limited to, L3 intra-frequency measurement or inter-frequency measurement. When the UE receives configuration information of a measurement object, the UE reports a measurement result within the first delay after a first measurement event is triggered.

[0184] In the embodiment of the present disclosure, for the measurement of the CSI-RS for intra-frequency measurement, the first delay may be represented as TCSI-RS_measurement_period_intra. For the measurement of the CSI-RS for inter-frequency measurement, the first delay is TCSI-RS_measurement_period_inter. However, it is not limited thereto, and the first delay may also be represented in other ways.

[0185] In the embodiment of the present disclosure, the first delay is obtained based on a first factor, that is, the first factor is the basis for calculating the first delay. The first factor corresponds to a cell measurement period. For example, the first factor may be represented as Mmeas_period_w / o_gaps. However, it is not limited thereto, and the first factor may also be represented in other ways.

[0186] Similarly, the second delay is obtained based on a second factor, and the second factor also corresponds to a cell measurement period.

[0187] In the embodiment of the present disclosure, the first factor is less than the second factor.

[0188] The following description will be given by taking intra-frequency measurement without measurement gaps as an example:

[0189] In the embodiment of the present disclosure, for UEs in FR2-1 (frequency range 2-1, which may refer to a frequency range of 24.25 GHz to 52.6 GHz), the first factor and the second factor have different values according to the power class of the UE.

[0190] As an example, if the UE does not support a capability to receive beams in multiple directions simultaneously, or the UE does not support a capability to activate multiple antenna panels simultaneously, or the UE supports the capability to receive beams in different directions simultaneously or the capability to activate multiple antenna panels simultaneously, but the beam reception in only one direction is activated, then:

[0191] For a UE of a power class 1, the second factor is Mmeas_period_w / o_gaps=X1. For example, X1=40.

[0192] For a UE of a power class 2 or 3 or 4 or 5, the second factor is Mmeas_period_w / o_gaps=Y1. For example, Y1=24.

[0193] When the UE receives the first message and after first measurement is triggered, if the UE transmits a layer 3 measurement report to the base station for at least once based on the CSI-RS resources within a first predetermined time, the UE transmits the first measurement result to the base station within the first delay.

[0194] For example, if the following condition is satisfied: the UE has reported a valid layer 3 (L3)-reference signal receiving power (RSRP) measurement report of the SSB based on this CSI-RS for at least once within a first predetermined time (e.g., Z1seconds), the first factor Mmeas_period_w / o_gapsmay be decreased as follows:

[0195] For a UE of a power class 1, the first factor is Mmeas_period_w / o_gaps=X2. X2is less than the above X1. For example, X2=5.

[0196] For a UE of a power class 2 or 3 or 4 or 5, the first factor is Mmeas_period_w / o_gaps=Y2. Y2is less than the above Y1. For example, Y2=3.

[0197] Other situations such as inter-frequency measurement or intra-frequency measurement with configured measurement gaps can be deduced in the same manner and will not be repeated.

[0198] In the communication system, when the UE is configured in carrier aggregation (CA) or dual connectivity (DC), multiple carries (also expressed as multiple cells) may be used in the communication system. The primary cell (PCell) is the only serving cell that ensures RRC connection of the UE in CA or DC. In the DC system, there is a PCell in the master cell group (MCG). The primary secondary cell (PSCell) is a serving cell in the secondary cell group (SCG) in the DC system, and is used to ensure the connection of the UE in the SCG and transmit control signals. The secondary cells (SCells) are serving cells other than PCell and PSCell in the CA or DC system.

[0199] In the embodiment of the present disclosure, if the UE is configured in the CA or DC system, the first message includes that transmitting beams of at least two SSBs configured by the base station are fully or partially overlapped, and the first measurement is related to secondary cell, for example, when the configuration information of the measurement object received by the UE is the measurement of SCell, the UE transmits the first measurement result to the base station within the first delay after a first measurement is triggered.

[0200] When the UE does not receive the first message, the measurement reporting delay of the SCell is the same as that of the PCell or PSCell, and the measurement includes intra-frequency measurement or inter-frequency measurement or f a primary synchronization signalRAT measurement and also includes measurement without or with measurement gaps.

[0201] For the intra-frequency measurement without measurement gaps, the UE shall be able to detect / identify a new detectable intra-frequency cell within a first delay T1, that is, the UE shall be able to detect / identify a new detectable intra-frequency cell at a time point no later than the first delay T1.

[0202] For the intra-frequency measurement with configured measurement gaps, when the UE is configured with measurement gaps, the UE shall be able to detect / identify a new detectable intra-frequency cell within a first delay T2, that is, the UE shall be able to detect / identify a new detectable intra-frequency cell at a time point no later than the first delay T2.

[0203] Similarly, the embodiment of the present disclosure can also be applied to inter-frequency measurement or inter-RAT measurement, in the inter-frequency or inter-RAT measurement, the UE shall be able to detect / identify a new detectable inter-frequency cell / inter-RAT cell, within a first delay T3, that is, the UE shall be able to detect / identify a new detectable inter-frequency cell / inter-RAT cell at a time point no later than the first delay T3.

[0204] In the embodiment of the present disclosure, if the first message includes that transmitting beams of at least two SSBs configured by the base station are fully or partially overlapped, the first delay is obtained based on the first factor and a third factor, and the second delay is obtained based on the second factor and a fourth factor. The first factor and the second factor correspond to a cell measurement period, and the third factor and the fourth factor correspond to a synchronization signal detection time.

[0205] In the embodiment of the present disclosure, the first factor is less than the second factor; and / or, the third factor is less than the fourth factor.

[0206] The following description will be given by taking intra-frequency measurement without measurement gaps as an example:

[0207] When the UE is not indicated to report the first measurement result of the SSB index, the first delay T1 may be represented as Tidentify_intra_without_index. However, it is not limited thereto, and the first delay may also be represented in other ways. Wherein,

[0208] Tidentify_intra_without_index= (TPSS / SSS_sync_intra+ TSSB_measurement_period_intra) ms

[0209] For UEs in FR2-1, TPSS / SSS_sync_intrais the time period of a primary synchronization signal (PSS) and a secondary synchronization signal (SSS) detection, and has different values depending on different parameter sets. For example, based on different parameters such as discontinuous reception (DRX) and SSB-based measurement timing configuration (SMTC) cycle, TPSS / SSS_sync_intrahas different values.

[0210] TSSB_measurement_period_intrais the SSB measurement period, and has different values depending on different parameter sets. For example, based on different parameters such as DRX and SMTC, TSSB_measurement_period_intrahas different values.

[0211] In an example, TPSS / SSS_sync_intramay be obtained from the following table 1:

[0212] [Table 1]

[0213]

[0214] In this example, the third factor may be represented as Mpss / sss_sync_w / o_gaps. However, it is not limited thereto, and the third factor may also be represented in other ways.

[0215] In another example, TSSB_measurement_period_intramay be obtained from the following table 2:

[0216] [Table 2]

[0217]

[0218] In this example, the first factor may be represented as Mmeas_period_w / o_gaps. However, it is not limited thereto, and the first factor may also be represented in other ways.

[0219] In the embodiment of the present disclosure, for UEs in FR2-1, the first factor, the second factor, the third factor and the fourth factor have different values depending on the power class of the UE.

[0220] As an example, if the UE does not support a capability to receive beams in multiple directions simultaneously, or the UE does not support a capability to activate multiple antenna panels simultaneously, or the UE supports the capability to receive beams in different directions simultaneously or the capability to activate multiple antenna panels simultaneously, but the beam reception in only one direction is activated, then:

[0221] For a UE of a power class 1, the second factor is Mmeas_period_w / o_gaps=X1. For example, X1=40.

[0222] For a UE of a power class 2 or 3 or 4 or 5, the second factor is Mmeas_period_w / o_gaps=Y1. For example,Y1=24.

[0223] For a UE of a power class 1, the fourth factor is Mpss / sss_sync_w / o_gaps=X3. For example, X3=40.

[0224] For a UE of a power class 2 or 3 or 4 or 5, the fourth factor is Mpss / sss_sync_w / o_gaps=Y3. For example, Y3=24.

[0225] When the UE receives the first message and after first measurement is triggered, if the UE has transmitted a layer 3 measurement report of a primary cell to the base station for at least once based on the SSB within a second predetermined time, the UE transmits the first measurement result to the base station within the first delay.

[0226] For example, if the following condition is satisfied: the UE has reported a valid L3-RSRP measurement report of the PCell based on SSB for at least once within the second predetermined time (e.g., Z2seconds), the measurement reporting delay of the SCell is:

[0227] For a UE of a power class 1, the third factor is Mpss / sss_sync_w / o_gaps=X4. X4is less than the above X3. For example, X4=5.

[0228] For a UE of a power class 2 or 3 or 4 or 5, the third factor is Mpss / sss_sync_w / o_gaps=Y4. Y4is less than the above Y3. For example, Y4=3.

[0229] For a UE of a power class 1, the first factor is Mmeas_period_w / o_gaps=X5. X5is less than the above X1. For example, X5=5.

[0230] For a UE of a power class 2 or 3 or 4 or 5, the first factor is Mmeas_period_w / o_gaps=Y5. Y5is less than the above Y1. For example, Y5=3.

[0231] The following description will be given by taking intra-frequency measurement with configured measurement gaps as an example:

[0232] When the UE is not indicated to report the first measurement result of the SSB index, the first delay T2 may be represented as Tidentify_intra_without_index. However, it is not limited thereto, and the first delay may also be represented in other ways. Wherein,

[0233] Tidentify_intra_without_index= ( TPSS / SSS_sync_intra+ TSSB_measurement_period_intra) ms

[0234] For UEs in FR2-1, TPSS / SSS_sync_intrais the detection time of the synchronization signal (PSS and SSS), and has different values depending on different parameter sets. For example, based on different parameters such as DRX and SMTC cycle, TPSS / SSS_sync_intrahas different values.

[0235] TSSB_measurement_period_intrais the SSB measurement period, and has different values depending on different parameter sets. For example, based on different parameters such as DRX and SMTC, TSSB_measurement_period_intrahas different values.

[0236] In an example, TPSS / SSS_sync_intramay be obtained from the following table 3:

[0237] [Table 3]

[0238]

[0239] In this example, the third factor may be represented as Mpss / sss_sync_with_gaps. However, it is not limited thereto, and the third factor may also be represented in other ways.

[0240] In another example, TSSB_measurement_period_intramay be obtained from the following table 4:

[0241] [Table 4]

[0242]

[0243] In this example, the first factor may be represented as Mmeas_period with_gaps. However, it is not limited thereto, and the first factor may also be represented in other ways.

[0244] In the embodiment of the present disclosure, for UEs in FR2-1, the first factor, the second factor, the third factor and the fourth factor have different values depending on the power class of the UE.

[0245] As an example, if the UE does not support a capability to receive beams in multiple directions simultaneously, or the UE does not support a capability to activate multiple antenna panels simultaneously, or the UE supports the capability to receive beams in different directions simultaneously or the capability to activate multiple antenna panels simultaneously, but the beam reception in only one direction is activated, then:

[0246] For a UE of a power class 1, the second factor is Mmeas_period with_gaps=X6. For example, X6=40.

[0247] For a UE of a power class 2 or 3 or 4 or 5, the second factor is Mmeas_period with_gaps=Y6. For example, Y6=24.

[0248] For a UE of a power class 1, the fourth factor is Mpss / sss_sync_with_gaps=X7. For example, X7=40.

[0249] For a UE of a power class 2 or 3 or 4 or 5, the fourth factor is Mpss / sss_sync_with_gaps=Y7. For example, Y7=24.

[0250] When the UE receives the first message and after first measurement is triggered, if the UE has transmitted a layer 3 measurement report of a primary cell to the base station for at least once based on the SSB within a second predetermined time, the UE transmits the first measurement result to the base station within the first delay.

[0251] For example, if the following condition is satisfied: the UE has reported a valid L3-RSRP measurement report of the PCell based on SSB for at least once within the second predetermined time (e.g., Z3seconds), the measurement reporting delay of the SCell is:

[0252] For a UE of a power class 1, the third factor is Mpss / sss_sync_with_gaps=X8. X8is less than the above X7. For example, X8=5.

[0253] For a UE of a power class 2 or 3 or 4 or 5, the third factor is Mpss / sss_sync_with_gaps=Y8. Y8is less than the above Y7. For example, Y8=3.

[0254] For a UE of a power class 1, the first factor is Mmeas_period with_gaps=X9. X9is less than the above X6. For example, X9=5.

[0255] For a UE of a power class 2 or 3 or 4 or 5, the first factor is Mmeas_period with_gaps=Y9. Y9is less than the above Y6. For example, Y9=3.

[0256] Other situations such as inter-frequency measurement can be deduced in the same manner and will not be repeated.

[0257] In the embodiment of the present disclosure, the UE may also execute the following.

[0258] In step S201, a second message is transmitted to the base station, the second message including at least one capability supported by the UE.

[0259] The at least one capability supported by the UE includes at least one of the following:

[0260] (1) a capability to receive beams in multiple directions simultaneously;

[0261] (2) a capability to activate multiple antenna panels simultaneously, the beam received by at least one antenna panel being different from the beams received by other antenna panels in direction;

[0262] for example, the UE supports the simultaneous activation of N antenna panels (N is greater than or equal to 2), wherein the receiving beam of no less than one antenna panel is different from the receiving beams of other antenna panels in direction;

[0263] (3) a capability of fast beam sweeping and measurement.

[0264] In the embodiment of the present disclosure, the second message may be transmitted in the UECapabilityInformation.

[0265] Optionally, different capabilities of the UE may be transmitted through one second message or multiple second messages. It will not be limited in the embodiment of the present disclosure.

[0266] In step S202, after second measurement is triggered, a second measurement result is transmitted to the base station within a third delay.

[0267] The third delay is less than the second delay.

[0268] For example, the UE supports the capability to receive beams in different directions simultaneously, or the UE supports the simultaneous activation of N antenna panels (N is greater than or equal to 2), wherein the receiving beams of no less than one antenna panel is different from the receiving beams of other antenna panels in direction. When the UE is configured as single-carrier communication, in an RRC connected state (RRC_CONNECTED), the UE executes cell measurement or beam measurement upon receiving the measurement configuration information from the gNB. If the measurement object is triggered based on an event, the UE reports the second measurement result within less than the third delay after a condition event point A of the event is satisfied.

[0269] The second measurement includes, but not limited to, at least one of the following: layer 3 (L3) measurement, layer 1 (L1)-RSRP measurement, L1-signal to interference plus noise ratio (SINR) measurement, radio link monitor (RLM) measurement, beam failure detection (BFD) measurement, candidate beam detection (CBD) measurement, or the like.

[0270] In the embodiment of the present disclosure, the third delay is obtained based on a fifth factor and a sixth factor; the second delay is obtained based on the second factor and the fourth factor; the second factor and the fifth factor correspond to a cell measurement period; and, the fourth factor and the sixth factor correspond to a synchronization signal detection time.

[0271] In the embodiment of the present disclosure, the fifth factor is less than the second factor; and / or, the sixth factor is less than the fourth factor.

[0272] Optionally, the second factor is N1 times of the fifth factor; and / or, the fourth factor is N2 times of the sixth factor, wherein both N1 and N2 are positive integers greater than or equal to 2.

[0273] The following description will be given by taking intra-frequency measurement without measurement gaps as an example:

[0274] In this example, the fifth factor may be represented as Mmeas_period_w / o_gaps, and the sixth factor may be represented as Mpss / sss_sync_w / o_gaps. However, it is not limited thereto, and the fifth factor and the sixth factor may also be represented in other ways.

[0275] In the embodiment of the present disclosure, for UEs in FR2-1, the fifth factor, the second factor, the sixth factor and the fourth factor have different values depending on the power class of the UE.

[0276] As an example, if the UE does not support a capability to receive beams in multiple directions simultaneously, or the UE does not support a capability to activate multiple antenna panels simultaneously, or the UE supports the capability to receive beams in different directions simultaneously or the capability to activate multiple antenna panels simultaneously, but the beam reception in only one direction is activated, then:

[0277] For a UE of a power class 1, the second factor is Mmeas_period_w / o_gaps=X1. For example, X1=40.

[0278] For a UE of a power class 2 or 3 or 4 or 5, the second factor is Mmeas_period_w / o_gaps=Y1. For example, Y1=24.

[0279] For a UE of a power class 1, the fourth factor is Mpss / sss_sync_w / o_gaps=X3. For example, X3=40.

[0280] For a UE of a power class 2 or 3 or 4 or 5, the fourth factor is Mpss / sss_sync_w / o_gaps=Y3. For example, Y3=24.

[0281] When the UE performs measurement on the activated PCell or PSCell, if the measurement object is based on the SSB, in a state where the UE activates antenna panels capable of receiving beams in different directions simultaneously or in a mode in which UE can receive beams in different directions simultaneously, and the UE supports the capability of fast beam sweeping and measurement, based on the second message, compared with the fourth factor, the sixth factor Mpss / sss_sync_w / o_gapsmay be decreased as:

[0282] For a UE of a power class 1, the sixth factor is Mpss / sss_sync_w / o_gaps=X10. X10is less than the above X3. Optionally, X10= X3 / N2.

[0283] For a UE of a power class 2 or 3 or 4 or 5, the sixth factor is Mpss / sss_sync_w / o_gaps=Y10. Y10is less than the above Y3. Optionally, Y10= Y3 / N2.

[0284] N2 is a positive integer greater than or equal to 2.

[0285] Optionally, based on the first message and the second message, the sixth factor may be less than the third factor, that is, X10is less than the above X4, and Y10is less than the above Y4.

[0286] Similarly, relative to the second factor, the fifth factor Mmeas_period_w / o_gapsmay be decreased as follows:

[0287] For a UE of a power class 1, the fifth factor is Mmeas_period_w / o_gaps=X11. X11is less than the above X1. Optionally, X11= X1 / N1.

[0288] For a UE of a power class 2 or 3 or 4 or 5, the first factor is Mmeas_period_w / o_gaps=Y11. Y11is less than the above Y1. Optionally, Y11= Y1 / N1.

[0289] N1 is a positive integer greater than or equal to 2.

[0290] Optionally, based on the first message and the second message, the fifth factor may be less than the first factor, that is, X11is less than the above X2or X5, and Y11is less than the above Y2or Y5.

[0291] The following description will be given by taking intra-frequency measurement with measurement gaps as an example:

[0292] In this example, the fifth factor may be represented as Mmeas_period with_gaps, and the sixth factor may be represented as Mpss / sss_sync_with_gaps. However, it is not limited thereto, and the fifth factor and the sixth factor may also be represented in other ways.

[0293] In the embodiment of the present disclosure, for UEs in FR2-1, the fifth factor, the second factor, the sixth factor and the fourth factor have different values depending on the power class of the UE.

[0294] As an example, if the UE does not support a capability to receive beams in multiple directions simultaneously, or the UE does not support a capability to activate multiple antenna panels simultaneously, or the UE supports the capability to receive beams in different directions simultaneously or the capability to activate multiple antenna panels simultaneously, but the beam reception in only one direction is activated, then:

[0295] For a UE of a power class 1, the second factor is Mmeas_period with_gaps=X6. For example, X6=40.

[0296] For a UE of a power class 2 or 3 or 4 or 5, the second factor is Mmeas_period with_gaps=Y6. For example, Y6=24.

[0297] For a UE of a power class 1, the fourth factor is Mpss / sss_sync_with_gaps=X7. For example, X7=40.

[0298] For a UE of a power class 2 or 3 or 4 or 5, the fourth factor is Mpss / sss_sync_with_gaps=Y7. For example, Y7=24.

[0299] When the UE performs measurement on the activated PCell or PSCell, if the measurement object is based on the SSB, in a state where the UE activates antenna panels capable of receiving beams in different directions simultaneously or in a mode in which UE can receive beams in different directions simultaneously, and the UE supports the capability of fast beam sweeping and measurement, based on the second message, compared with the fourth factor, the sixth factor Mpss / sss_sync_w / o_gapsmay be decreased as:

[0300] For a UE of a power class 1, the sixth factor is Mpss / sss_sync_w / o_gaps=X12. X12is less than the above X7. Optionally, X12= X7 / N2.

[0301] For a UE of a power class 2 or 3 or 4 or 5, the sixth factor is Mpss / sss_sync_w / o_gaps=Y12. Y12is less than the above Y7. Optionally, Y12= Y7 / N2.

[0302] N2 is a positive integer greater than or equal to 2.

[0303] Optionally, based on the first message and the second message, the sixth factor may be less than the third factor, that is, X10is less than the above X8, and Y10is less than the above Y8.

[0304] Similarly, relative to the second factor, the fifth factor Mmeas_period w / o_gapsmay be decreased as follows:

[0305] For a UE of a power class 1, the fifth factor is Mmeas_period with_gaps=X13. X13is less than the above X6. Optionally, X13= X6 / N1.

[0306] For a UE of a power class 2 or 3 or 4 or 5, the first factor is Mmeas_period with_gaps=Y13. Y13is less than the above Y6. Optionally, Y13= Y6 / N1.

[0307] N1 is a positive integer greater than or equal to 2.

[0308] Optionally, based on the first message and the second message, the fifth factor may be less than the first factor, that is, X11is less than the above X2or X9, and Y11is less than the above Y2or Y9.

[0309] It is to be noted that the above N1 and N2 may be the same or different from the number N of beams or antenna panels.

[0310] Based on the first message and the second message, the measurement reporting delay is reduced, and the UE can report the measurement result more quickly. For the gNB's behaviors based on the measurement result, such as handover, the handover process of the gNB can be completed more quickly. Accordingly, the reliability and efficiency of mobility are improved, and the performance of mobility is better ensured. For example, when the UE is moving and the UE satisfies a cell handover condition, a shorter measurement reporting delay can make the UE complete the whole handover process more quickly, and it is ensured that the UE handovers to a more suitable cell within a shorter time.

[0311] Other situations such as inter-frequency measurement can be deduced in the same manner and will not be repeated.

[0312] In the embodiment of the present disclosure, the UE may also execute the following.

[0313] In step 301, a third message is transmitted to the base station, the third message including that the UE also supports a capability to perform layer 3 (L3) measurement and layer 1 (L1) measurement simultaneously in a situation where the UE supports the capability to receive beams in multiple directions simultaneously, a first direction among the plurality of directions is configured for layer 3 measurement and a second direction among the plurality of directions is configured for layer 1 measurement.

[0314] In step S302, when third measurement is triggered, a third measurement result is transmitted to the base station within a fourth delay, wherein the fourth delay is less than the second delay.

[0315] In the embodiment of the present disclosure, the UE reports a third message, the third message including that the UE supports the simultaneous reception of beams in different directions, some of which are configured for L3 measurement and other of which are configured for L1 measurement, and the UE supports the capabilities to receive beams in different directions simultaneously and perform simultaneous measurement. Based on the condition, the L3 measurement reporting delay or L1 measurement reporting delay can be further reduced. The measurement reporting delay is reduced, and the UE can report the measurement result more quickly. For example, the L3 measurement reporting delay is reduced. For the gNB's behaviors based on the measurement result, such as handover, the handover process of the gNB can be completed more quickly. Accordingly, the reliability and efficiency of mobility are improved, and the performance of mobility is better ensured. For example, when the UE is moving and the UE satisfies a cell handover condition, a shorter measurement reporting delay can make the UE complete the whole handover process more quickly, and it is ensured that the UE handovers to a more suitable cell within a shorter time. Moreover, the L1 measurement reporting delay is reduced, the UE reports the measurement result more quickly or tracks the change of the radio link quality or the change of the beam quality more quickly, and the performance of the UE in monitoring the radio link quality or beam management is improved.

[0316] In the embodiment of the present disclosure, in a situation where the SSB time symbols related to layer 1 measurement are overlapped with the SSB time symbols related to layer 3 measurement, the fourth delay is obtained based on a seventh factor; the second delay is obtained based on an eighth factor; and, the seventh factor and the eighth factor correspond to a layer 1 measurement period.

[0317] The related SSB time symbols may be, for example, but not limited to, an SSB symbol and symbols before and after it.

[0318] In the embodiment of the present disclosure, the seventh factor is less than the eighth factor.

[0319] In this example, the seventh factor may be represented as Klayer1_measurement. However, it is not limited thereto, and the seventh factor may also be represented in other ways.

[0320] As an example, if the UE has the capabilities to receive beams in different directions simultaneously and support L3 and L1 measurement simultaneously, when symbols of the L1-RSRP measurement based on the SSB or RLM measurement or BFD measurement or CBD measurement and the SSB symbol of L3 measurement and symbols before and after it are overlapped in the time domain, the UE can perform L3 measurement and L1 measurement simultaneously, and the seventh factor is Klayer1_measurement=1. Otherwise, if the UE does not transmit the third message to the base station, that is, when symbols of the L1-RSRP measurement based on the SSB or RLM measurement or BFD measurement or CBD measurement and the SSB symbol of L3 measurement and symbols before and after it are overlapped in the time domain, but the UE does not support the capabilities to receive beams in different directions simultaneously and perform L3 and L1 measurement simultaneously, the eighth factor is Klayer1_measurement=1.5.

[0321] In the embodiment of the present disclosure, if the layer 1 measurement includes layer 1 RSRP measurement, the fourth delay is obtained based on a ninth factor; the second delay is obtained based on a tenth factor; and, the ninth factor and the tenth factor correspond to a time domain position relationship between a reference signal and a reference signal for layer 3 measurement.

[0322] In the embodiment of the present disclosure, the ninth factor is less than the tenth factor.

[0323] As an example, in the L1 measurement, the UE performs L1-RSRP measurement. When the UE is configured with L1-RSRP measurement, the UE performs L1-RSRP measurement on the configured SSB and / or CSI-RS, and performs reporting.

[0324] By taking L1-RSRP measurement based on the SSB as an example, the measurement period may be represented as TL1-RSRP_Measurement_Period_SSB, and may be obtained from the following table 5:

[0325] [Table 5]

[0326]

[0327] The factor P is obtained according to Psharing factor. In this example, the ninth factor may be represented as Psharing factor. However, it is not limited thereto, and the ninth factor may also be represented in other ways.

[0328] In the embodiment of the present disclosure, if the UE does not support the capabilities to receive beams in different directions simultaneously and perform L3 measurement and L1 measurement simultaneously, and when the UE satisfies that condition that the SSB resource for L1-RSRP based on the SSB is overlapped in the time domain with the SSB symbol of L3 measurement and symbols before and after the SSB symbol of L3 measurement, the tenth factor is Psharing factor=3.

[0329] If the UE reports that it supports the capabilities to receive beams in different directions simultaneously and perform L3 measurement and L1 measurement simultaneously (i.e., the third message), and when the SSB symbol of L1-RSRP measurement is overlapped or partially overlapped with the SSB symbol of L3 measurement and symbols before and after the SSB symbol of L3 measurement, the ninth factor is Psharing factor=1, thereby reducing the measurement period of L1.

[0330] The L1 measurement includes, but not limited to, RSRP, and may also include the following measurement: L1-SINR measurement, RLM measurement, BFD measurement, CBD measurement, and so on, which will not be repeated.

[0331] In the embodiment of the present disclosure, based on the first message, the second message and / or the third message, the measurement reporting delay is reduced, and the UE can report the measurement result more quickly. For example, the L3 measurement reporting delay is reduced. For the gNB's behaviors based on the measurement result, such as handover, the handover process of the gNB can be completed more quickly. Accordingly, the reliability and efficiency of mobility are improved, and the performance of mobility is better ensured. For example, when the UE is moving and the UE satisfies a cell handover condition, a shorter measurement reporting delay can make the UE complete the whole handover process more quickly, and it is ensured that the UE handovers to a more suitable cell within a shorter time. Moreover, the L1 measurement reporting delay is reduced, the UE reports the measurement result more quickly or tracks the change of the radio link quality or the change of the beam quality more quickly, and the performance of the UE in monitoring the radio link quality or beam management is improved.

[0332] In summary, the first measurement, the second measurement or the third measurement includes, but not limited to, at least one of the following: layer 3 measurement, layer 1 RSRP measurement, layer 1 SINR measurement, RLM measurement, BFD measurement, CBD measurement or the like. It should be understood that the above examples are only schematic descriptions and do not constitute limitations to the embodiment of the present disclosure, and appropriate alterations based on these examples can also be applied to the present disclosure and shall fall into the protection scope of the present disclosure.

[0333] In the embodiment of the present disclosure, based on the radio resource management (RRM) or layer 1 (L1) measurement of the UE, the UE reports the measurement result, and the gNB may execute the corresponding communication method and steps according to the measurement result or according to the regulations.

[0334] In the embodiment of the present disclosure, when the UE performs RRM measurement or L1 measurement, the measurement reporting delay is reduced according to the newly introduced message and condition.

[0335] In an embodiment of the present disclosure, a method executed by a UE in a communication system is further provided. As shown in FIG. 5, the method includes the following.

[0336] In step S501, a fourth message is transmitted to a base station, the fourth message including at least one capability supported by the UE.

[0337] The at least one capability supported by the UE includes at least one of the following:

[0338] (1) a capability of fast beam sweeping and measurement; and

[0339] (2) a capability to perform layer 3 measurement and layer 1 measurement simultaneously in a situation where the UE supports a capability to receive beams in multiple directions simultaneously, a first direction among the plurality of directions is configured for layer 3 measurement and a second direction among the plurality of directions is configured for layer 1 measurement.

[0340] In step S502, after fourth measurement is triggered, a fourth measurement result is transmitted to the base station within a fifth delay, wherein the fifth delay is less than a sixth delay, and the sixth delay is a measurement reporting delay corresponding to a situation where the UE does not support the at least one capability.

[0341] In the embodiment of the present disclosure, the situation where the UE does not support the at least one capability includes at least one of the following:

[0342] (1) the UE does not transmit the fourth message to the base station;

[0343] that is, if the UE does not transmit the fourth message to the base station, it defaults that the UE does not support the at least one capability;

[0344] (2) the UE transmits a fifth message to the base station, the fifth message including that the UE does not support the at least one capability; and

[0345] (3) beam reception of the UE in only one direction is activated.

[0346] Even if the UE transmits the fourth message to the base station, but the UE states allows the beam reception in only one direction to be activated, the condition of reducing the measurement reporting delay is also not satisfied.

[0347] In the embodiment of the present disclosure, the at least one capability supported by the UE further includes at least one of the following:

[0348] (1) a capability to receive beams in multiple directions simultaneously;

[0349] (2) a capability to activate multiple antenna panels simultaneously, the beam received by at least one antenna panel being different from the beams received by other antenna panels in direction.

[0350] The specific description of the at least one capability supported by the UE can refer to the above description and will not be repeated here.

[0351] Optionally, different capabilities of the UE may be transmitted through one fourth message or multiple fourth messages. It will not be limited in the embodiment of the present disclosure.

[0352] In the embodiment of the present disclosure, the fifth delay is obtained based on an eleventh factor and a twelfth factor; the sixth delay is obtained based on a thirteenth factor and a fourteenth factor; the eleventh factor and the thirteenth factor correspond to a cell measurement period; and, the twelfth factor and the fourteenth factor correspond to a synchronization signal detection time.

[0353] In the embodiment of the present disclosure, the eleventh factor is less than the thirteenth factor; and / or, the twelfth factor is less than the fourteenth factor.

[0354] Optionally, the thirteenth factor is N3 times of the eleventh factor; and / or, the fourteenth factor is N4 times of the twelfth factor, wherein both N1 and N2 are positive integers greater than or equal to 2.

[0355] The following description will be given by taking intra-frequency measurement without measurement gaps as an example:

[0356] In this example, the eleventh factor may be represented as Mmeas_period_w / o_gaps, and the twelfth factor may be represented as Mpss / sss_sync_w / o_gaps. However, it is not limited thereto, and the eleventh factor and the twelfth factor may also be represented in other ways.

[0357] In the embodiment of the present disclosure, for UEs in FR2-1, the eleventh factor, the thirteenth factor, the twelfth factor and the fourteenth factor have different values depending on the power class of the UE.

[0358] As an example, if the UE does not support a capability to receive beams in multiple directions simultaneously, or the UE does not support a capability to activate multiple antenna panels simultaneously, or the UE supports the capability to receive beams in different directions simultaneously or the capability to activate multiple antenna panels simultaneously, but the beam reception in only one direction is activated, then:

[0359] For a UE of a power class 1, the thirteenth factor is Mmeas_period_w / o_gaps=X14. For example, X14=40.

[0360] For a UE of a power class 2 or 3 or 4 or 5, the thirteenth factor is Mmeas_period_w / o_gaps=Y14. For example, Y14=24.

[0361] For a UE of a power class 1, the fourteenth factor is Mpss / sss_sync_w / o_gaps=X15. For example, X15=40.

[0362] For a UE of a power class 2 or 3 or 4 or 5, the fourteenth factor is Mpss / sss_sync_w / o_gaps=Y15. For example, Y15=24.

[0363] When the UE performs measurement on the activated PCell or PSCell, if the measurement object is based on the SSB, in a state where the UE activates antenna panels capable of receiving beams in different directions simultaneously or in a mode in which UE can receive beams in different directions simultaneously, and the UE supports the capability of fast beam sweeping and measurement, based on the fourth message, compared with the fourteenth factor, the twelfth factor Mpss / sss_sync_w / o_gapsmay be decreased as:

[0364] For a UE of a power class 1, the twelfth factor is Mpss / sss_sync_w / o_gaps=X16. X16is less than the above X15. Optionally, X16= X15 / N4.

[0365] For a UE of a power class 2 or 3 or 4 or 5, the twelfth factor is Mpss / sss_sync_w / o_gaps=Y16. Y16is less than the above Y15. Optionally, Y16= Y15 / N4.

[0366] N4 is a positive integer greater than or equal to 2.

[0367] Similarly, relative to the thirteenth factor, the eleventh factor Mmeas_period_w / o_gapsmay be decreased as follows:

[0368] For a UE of a power class 1, the eleventh factor is Mmeas_period_w / o_gaps=X17. X17is less than the above X14. Optionally, X17= X14 / N3.

[0369] For a UE of a power class 2 or 3 or 4 or 5, the first factor is Mmeas_period_w / o_gaps=Y17. Y17is less than the above Y14. Optionally, Y17=Y14 / N3.

[0370] N3 is a positive integer greater than or equal to 2.

[0371] The following description will be given by taking intra-frequency measurement with configured measurement gaps as an example:

[0372] In this example, the eleventh factor may be represented as Mmeas_period with_gaps, and the twelfth factor may be represented as Mpss / sss_sync_with_gaps. However, it is not limited thereto, and the eleventh factor and the twelfth factor may also be represented in other ways.

[0373] In the embodiment of the present disclosure, for UEs in FR2-1, the eleventh factor, the thirteenth factor, the twelfth factor and the fourteenth factor have different values depending on the power class of the UE.

[0374] As an example, if the UE does not support a capability to receive beams in multiple directions simultaneously, or the UE does not support a capability to activate multiple antenna panels simultaneously, or the UE supports the capability to receive beams in different directions simultaneously or the capability to activate multiple antenna panels simultaneously, but the beam reception in only one direction is activated, then:

[0375] For a UE of a power class 1, the thirteenth factor is Mmeas_period with_gaps=X18. For example, X18=40.

[0376] For a UE of a power class 2 or 3 or 4 or 5, the thirteenth factor is Mmeas_period with_gaps=Y18. For example, Y18=40.

[0377] For a UE of a power class 1, the fourteenth factor is Mpss / sss_sync_with_gaps=X19. For example, X19=40.

[0378] For a UE of a power class 2 or 3 or 4 or 5, the fourteenth factor is Mpss / sss_sync_with_gaps=Y19. For example, Y19=24.

[0379] When the UE performs measurement on the activated PCell or PSCell, if the measurement object is based on the SSB, in a state where the UE activates antenna panels capable of receiving beams in different directions simultaneously or in a mode in which UE can receive beams in different directions simultaneously, and the UE supports the capability of fast beam sweeping and measurement, based on the fourth message, compared with the fourteenth factor, the twelfth factor Mpss / sss_sync_w / o_gapsmay be decreased as:

[0380] For a UE of a power class 1, the twelfth factor is Mpss / sss_sync_with_gaps=X20. X20is less than the above X19. Optionally, X20= X19 / N4.

[0381] For a UE of a power class 2 or 3 or 4 or 5, the twelfth factor is Mpss / sss_sync_with_gaps=Y20. Y20is less than the above Y19. Optionally, Y20= Y19 / N4.

[0382] N4 is a positive integer greater than or equal to 2.

[0383] Similarly, relative to the thirteenth factor, the eleventh factor Mmeas_period_w / o_gapsmay be decreased as follows:

[0384] For a UE of a power class 1, the eleventh factor is Mmeas_period with_gaps=X21. X21is less than the above X18. Optionally, X21= X18 / N3.

[0385] For a UE of a power class 2 or 3 or 4 or 5, the first factor is Mmeas_period with_gaps=Y21. Y21is less than the above Y18. Optionally, Y21= Y18 / N3.

[0386] N3 is a positive integer greater than or equal to 2.

[0387] It is to be noted that the above N3 and N4 may be the same or different from the number N of beams or antenna panels.

[0388] Based on the fourth message, the measurement reporting delay is reduced, and the UE can report the measurement result more quickly. For the gNB's behaviors based on the measurement result, such as handover, the handover process of the gNB can be completed more quickly. Accordingly, the reliability and efficiency of mobility are improved, and the performance of mobility is better ensured. For example, when the UE is moving and the UE satisfies a cell handover condition, a shorter measurement reporting delay can make the UE complete the whole handover process more quickly, and it is ensured that the UE handovers to a more suitable cell within a shorter time.

[0389] Other situations such as inter-frequency measurement can be deduced in the same manner and will not be repeated.

[0390] In the embodiment of the present disclosure, if the capability supported by the UE is the capability to perform layer 3 measurement and layer 1 measurement simultaneously in a situation where the UE supports the capability to receive beams in multiple directions simultaneously, the first direction among the plurality of directions is configured for layer 3 measurement and the second direction among the plurality of directions is configured for layer 1 measurement, and the SSB time symbols related to layer 1 measurement are overlapped with the SSB time symbols related to layer 3 measurement, wherein,

[0391] the fifth delay is obtained based on a fifteenth factor; the sixth delay is obtained based on a sixteenth factor; and, the fifteenth factor and the sixteen factor correspond to a layer 1 measurement period.

[0392] In the embodiment of the present disclosure, the fifteenth factor is less than the sixteenth factor.

[0393] In the embodiment of the present disclosure, the fifteenth factor may be represented as Klayer1_measurement. However, it is not limited thereto, and the fifteenth factor may also be represented in other ways.

[0394] As an example, if the UE has the capabilities to receive beams in different directions simultaneously and support L3 and L1 measurement simultaneously, when symbols of the L1-RSRP measurement based on the SSB or RLM measurement or BFD measurement or CBD measurement and the SSB symbol of L3 measurement and symbols before and after it are overlapped in the time domain, the UE can perform L3 measurement and L1 measurement simultaneously, and the fifteenth factor is Klayer1_measurement=1. Otherwise, if the UE does not transmit the fourth message to the base station, that is, when symbols of the L1-RSRP measurement based on the SSB or RLM measurement or BFD measurement or CBD measurement are overlapped with the SSB symbol of L3 measurement and symbols before and after it in the time domain, but the UE does not support the capabilities to receive beams in different directions simultaneously and perform L3 and L1 measurement simultaneously, the sixteenth factor is Klayer1_measurement=1.5.

[0395] In the embodiment of the present disclosure, if the layer 1 measurement includes layer 1 RSRP measurement, the fifth delay is obtained based on a seventeenth factor; the sixth delay is obtained based on an eighteenth factor; and, the seventeenth factor and the eighteenth factor correspond to a time domain position relationship between a reference signal and a reference signal for layer 3 measurement.

[0396] In the embodiment of the present disclosure, the seventeenth factor is less than the eighteenth factor.

[0397] As an example, in the L1 measurement, the UE performs L1-RSRP measurement. When the UE is configured with L1-RSRP measurement, the UE performs L1-RSRP measurement on the configured SSB and / or CSI-RS, and performs reporting.

[0398] In this example, the seventeenth factor may be represented as Psharing factor. However, it is not limited thereto, and the seventeenth factor may also be represented in other ways.

[0399] In the embodiment of the present disclosure, if the UE does not support the capabilities to receive beams in different directions simultaneously and perform L3 measurement and L1 measurement simultaneously, and when the UE satisfies that condition that the SSB resource for L1-RSRP based on the SSB is overlapped in the time domain with the SSB symbol of L3 measurement and symbols before and after the SSB symbol of L3 measurement, the seventeenth factor is Psharing factor=3.

[0400] If the UE reports that it supports the capabilities to receive beams in different directions simultaneously and perform L3 measurement and L1 measurement simultaneously (i.e., the third message), and when the UE satisfies that the SSB symbol of L1-RSRP is overlapped or partially overlapped in the time domain with the SSB symbol of L3 measurement and symbols before and after the SSB symbol of L3 measurement, the eighteenth factor is Psharing factor=1, thereby reducing the measurement period of L1.

[0401] In the embodiment of the present disclosure, based on the fourth message, the measurement reporting delay is reduced, and the UE can report the measurement result more quickly. For example, the L3 measurement reporting delay is reduced. For the gNB's behaviors based on the measurement result, such as handover, the handover process of the gNB can be completed more quickly. Accordingly, the reliability and efficiency of mobility are improved, and the performance of mobility is better ensured. For example, when the UE is moving and the UE satisfies a cell handover condition, a shorter measurement reporting delay can make the UE complete the whole handover process more quickly, and it is ensured that the UE handovers to a more suitable cell within a shorter time. Moreover, the L1 measurement reporting delay is reduced, the UE reports the measurement result more quickly or tracks the change of the radio link quality or the change of the beam quality more quickly, and the performance of the UE in monitoring the radio link quality or beam management is improved.

[0402] In summary, the fourth measurement includes, but not limited to, at least one of the following: layer 3 measurement, layer 1 RSRP measurement, layer 1 SINR measurement, RLM measurement, BFD measurement, CBD measurement or the like. It should be understood that the above examples are only schematic descriptions and do not constitute limitations to the embodiment of the present disclosure, and appropriate alterations based on these examples can also be applied to the present disclosure and shall fall into the protection scope of the present disclosure.
