NODE, USER EQUIPMENT AND METHOD THEREOF IN WIRELESS COMMUNICATION SYSTEM

[0001] The application relates to the technical field of wireless communication, and more specifically, relates to a node, a user equipment and a method thereof in a wireless communication system.

[0002] 5G mobile communication technologies define broad frequency bands such that high transmission rates and new services are possible, and can be implemented not only in "Sub 6GHz" bands such as 3.5GHz, but also in "Above 6GHz" bands referred to as mmWave including 28GHz and 39GHz. In addition, it has been considered to implement 6G mobile communication technologies (referred to as Beyond 5G systems) in terahertz 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.

[0051] 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.

[0052] 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.

[0053] 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).

[0054] 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.

[0055] 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.

[0056] 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.

[0057] 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.

[0058] 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.

[0059] 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.

[0060] 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.

[0061] 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.

[0062] 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.

[0063] 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.

[0064] 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.).

[0065] 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.

[0066] 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.

[0067] 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.

[0068] 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).

[0069] 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.

[0070] 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.

[0071] 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.

[0072] 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).

[0073] 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.

[0074] 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.

[0075] 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.

[0076] 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.

[0077] 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.

[0078] 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.

[0079] 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.

[0080] 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.

[0081] 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.

[0082] 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.

[0083] 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).

[0084] Time Division Duplex (TDD) technology is widely used in communication systems as a multiplexing method. In a TDD communication system, a network node (e.g., a base station) and a user (e.g., a user equipment (UE)) use the same frequency resource for uplink and downlink communication on different time resources, respectively. However, such multiplexing makes both uplink and downlink limited by the allocated time resources, which in turn limits the coverage, latency and network capacity of the communication system. Sub-band Non-overlapping Full Duplex (SBFD) (or other subsequently evolved sub-band based full duplex technologies, names of which are not limited herein), as an evolution of the TDD technology, allows the communication network node and / or the user to be able to perform uplink and downlink communications simultaneously, thereby addressing the scheduling limitation of communication time resources in TDD.

[0085] In the communication system to which the SBFD technology is applied, the network further divides a carrier into a plurality of sub-band bandwidths, and performs uplink or downlink transmission simultaneously on these different sub-bands. How to provide an enhancement method to support the SBFD technology is a problem to be solved.

[0086] A method for enhancing UE measurement behaviors in a SBFD network is described below. When the UE is in RRC_CONNECTED, when downlink measurement it performs in the network supporting SBFD is performed on a normal TDD downlink time slot (or symbol) and a SBFD time slot (or symbol) respectively, measurement results may include measurement results by the UE of downlink signals (and / or channels) in these two time slots (or symbols). The measurement here includes, but not limited to, intra-frequency measurement and inter-frequency measurement configured by the network, Synchronization Signal Block (SSB) based Radio Link Monitoring (RLM) measurement, Channel-State Information - Reference Signal (CSI-RS) based RLM measurement, SSB based Beam Failure Detection (BFD) measurement, CSI-RS based BFD measurement, SSB based Candidate Beam Detection (CBD) measurement, CSI-RS based CBD measurement, Layer 1 Reference Signal Received Power (L1-RSRP) measurement, SSB based RSRP measurement, CSI-RS based RSRP measurement, Layer 1 Signal to Noise and Interference Ratio (L1-SINR) measurement, SSB based SINR measurement, CSI-RS based SINR measurement, etc. The following describes enhancement made to reporting of results of such measurements, improving accuracy of these measurement behaviors and the reported measurement results.

[0087] FIG. 4a illustrates a method 410 for modifying a measurement result of a UE affected by a base station in a network supporting SBFD according to embodiments of the present disclosure.

[0088] The method 410 includes: optionally, at 411, the UE reports, to a base station, information indicating that it is a UE with SBFD aware capability and / or a UE supporting SBFD measurement behavior enhancement via signaling such as UE capability, wherein information of SBFD aware and information of supporting the SBFD measurement behavior enhancement may be indicated independently by two information carriers (such as information elements), or may be indicated in combination by one information therein implicitly indicating two capabilities (for example, when the UE reports the information of SBFD aware, it is implied that the UE reports, to the base station, the information of supporting the SBFD measurement behavior enhancement). In the disclosure, the above information of SBFD aware and / or information of supporting the SBFD measurement behavior enhancement is called first information, and the name of the first information is not limited herein. Optionally, the first information may be reported by adding a new information element in UECapabilityInformation message. Optionally, the UE reporting, to the base station, the first information is in response to the UE receiving, from the base station, information for inquiring about the UE capability, and the name of the information for inquiring about UE capability is not limited herein.

[0089] At 412, the UE receives, from the base station, second information indicating SBFD uplink and downlink time slot and / or symbol configuration in the network. The name of the second information is not limited herein.

[0090] At 413, the UE receives, from the base station, third information indicating that it is used to modify the result of downlink measurement performed by the UE in the network supporting SBFD. Optionally, the third information indicates at least one of a modification quantity, an index, a type and a threshold, and at least one of the modification quantity or index or type or threshold indicated by the third information is used for measurement on an SBFD time unit, that is, for modifying the measurement on the SBFD time unit. Optionally, at least one of the modification quantity or index or type or threshold indicated by the third information is used for measurement on an non-SBFD time unit. The name of the third information is not limited herein.

[0091] At least one of the modification quantity, index, type and threshold indicated by the third information are described in detail below.

[0092] The third information may be a numerical value directly used to modify the measurement result, or a group of numbers corresponding to different modification values, or a group of types corresponding to different modification values. That is, the third information may directly and explicitly provide the numerical value for modifying the measurement result, or may be represented in other manners (numbers or types) mapped with different modification values.

[0093] A first representation of the third information is: when the third information indicates the numerical value directly used to modify the measurement result, it may be a positive number, a negative number, zero or a percentage. For example, the third information may be a numerical value indicated by information called SbfdMeasOffset, the numerical value may be a positive number, a negative number or zero and may be directly applied to the measurement result through operations (such as addition, subtraction, multiplication, division, etc.) to modify the measurement result.

[0094] A second representation of the third information is: when the third information indicates a group of numbers (for example, numbers or indexes) mapped with modification quantities for the measurement result, each number indicated by the third information may correspond to a preset modification quantity. Meanwhile, the second representation may also be combined with the first representation, that is, one of the numbers indicated by the third information (number 4 in Table 1 below) does not correspond to a preset modification quantity, but indicates that the network needs to indicate the specific modification quantity by other means (for example, the first representation above) when indicated by the third information. For example, the third information may be a number indicated by the information called SbfdMeasIndex, and a mapping relationship between numbers and the indicated modification quantities for the measurement result is shown in Table 1 below. Other mapping relationships are also possible.

[0095]

[0096] A third representation of the third information is: when the third information indicates a group of types corresponding to different modification quantities, the types may correspond to antenna configuration types of the base station currently supporting SBFD in the SBFD time slot (or symbol). A possible classification of antenna configuration types is determined by the number or ratio of antenna resources that the base station may use for downlink and / or uplink when the base station supporting SBFD operates on the SBFD time slot (or symbol).

[0097] Here, the antenna resources may include one or more of the number of antenna elements, the number of antenna panels, transmission power, etc. that the base station may actually perform downlink transmission and / or uplink reception on the corresponding time slot.

[0098] Optionally, description of the antenna resources in different antenna configuration types may be a specific number, such as 16 (antenna elements), 2 (antenna panels), 5 (watt transmission power), etc.

[0099] Optionally, description of the antenna resources in different antenna configuration types may be a ratio, which may be a numerical value (for example, 100% or 50%) or other similar description (for example, same or half) of the ratio of antenna resources that the base station may use for downlink or uplink transmission on the SBFD time slot (or symbol) to antenna resources that the base station may use for corresponding downlink or uplink transmission on the non-SBFD time slot (or symbol).

[0100] Optionally, the third representation of the third information may also be combined with other representations. For example, in case of Type 4 in the following example, the network needs to indicate the specific modification quantity by other means.

[0101] The name of specific antenna configuration type is not limited herein. For example, when the antenna configuration type is called "SBFD base station antenna configuration type" and the possible classification is described by the above ratio, various types of "SBFD base station antenna configuration type" and corresponding descriptions may be as shown in Table 2 below.

[0102]

[0103]

[0104] Optionally, a mapping relationship between various types of "SBFD base station antenna configuration type" and modification quantities (or modification or offset) for the measurement result may be shown in Table 3 below.

[0105]

[0106] A fourth representation of the third information is that the modification quantity indicated by the third information may be converted and applied to an event threshold corresponding to a configured measurement event. For example, the base station may convert the modification quantity indicated by the third information according to the ratio of the number of measurement objects or measurement resources allocated by the base station to the UE overlapping with (located in) the SBFD time slot (or symbol) to the number of the configured measurement objects or measurement resources overlapping with (located in) the non-SBFD time slot (or symbol), and apply the converted numerical value to the event threshold corresponding to the configured measurement event.

[0107] As shown in the above examples, the representation of the third information may be one of the above different representations or a combination of a plurality of representations.

[0108] At 414, the UE may perform measurement on the SBFD time slot (or symbol) and modify the measurement result generated by the measurement performed by the UE based on the second information and the third information received from the base station.

[0109] The modification by the UE of the measurement result may be performed by applying the modification quantity indicated by the third information to the corresponding single measurement value or multiple measurement values when the measurement objects or measurement resources thereof overlap with (or are located in) the SBFD time slot (or symbol), for example, adding the modification quantity to the corresponding single measurement value or multiple measurement values; or by applying the modification indicated by the third information to the corresponding single measurement value or multiple measurement values when the measurement objects or measurement resources thereof overlap with (or are located in) the non-SBFD time slot (or symbol), for example, subtracting the modification from the corresponding single measurement value or multiple measurement values; or converting the modification quantity indicated by the third information according to the ratio of the number of measurement objects or measurement resources allocated thereto overlapping with (located in) the SBFD time slot (or symbol) to the number of the configured measurement objects or measurement resources overlapping with (located in) the non-SBFD time slot (or symbol) and applying the converted numerical value to overall measurement results, for example, applying the converted numerical value to average value of the overall measurement results. Here, the overall measurement results are obtained by the UE which performs the measurement performing single measurement process or multiple measurement processes thereon based on an existing requirement.

[0110] Optionally, step 414 may include a first condition for the UE to perform step 414, that is, only when the difference between the measurement value measured by the UE on the SBFD time slot (or symbol) and the single measurement value or the average value of the multiple measurement values measured by the UE on the non-SBFD time slot (or symbol) is the modification quantity indicated by the third information (or the difference falls within a certain error range of the modification quantity), the UE modifies the measurement value base on the second information and the third information received from the base station.

[0111] At 415, the UE may report the measurement result modified based on the third information. Optionally, the measurement result is the measurement value of the measurement result on the SBFD time slot (or symbol) applied with the modification quantity or index or type indicated by the third message.

[0112] In the communication system where the SBFD technology is applied, the above method 410 is for the case that the antenna resources (including but not limited to the number of antenna elements, the number of antenna panels, input power, etc.) configured when performing normal TDD uplink or downlink are different from the antenna resources configured for uplink and downlink, respectively, when performing SBFD, for a network device (including but not limited to the base station and user equipment), when operating, that needs to be configured with both the normal TDD uplink and downlink time slot and / or symbol and the SBFD uplink and downlink time slot and / or symbol.

[0113] Through the above method 410, the network device may indicate, to other network devices in the communication system in communication via information (for example, the third information described above), change of antenna configuration on the above different time slots (or symbols) (for example, the normal TDD time slot (or symbol) or the SBFD time slot (or symbol), including but are not limited to, the difference between the numbers of antenna elements applied by the network device on the normal TDD time slot (or symbol) and the SBFD time slot (or symbol), the ratio of the numbers of antenna elements applied by the network device on the normal TDD time slot (or symbol) and the SBFD time slot (or symbol), the difference of transmission power applied by the network device on the normal TDD time slot (or symbol) and the SBFD time slot (or symbol), antenna configuration type used by the network device on specific type (for example, normal TDD or SBFD) of time slot (or symbol), etc., such that devices in the communication system, including the network device, may adjust accordingly in different communication processes.

[0114] A UE performing the measurement in the SBFD network may improve the accuracy of its measurement and the reliability of its reported measurement report by above method of modifying the measurement result or the measurement configuration. The method avoids adverse result that measurement results of the user equipment in different time units including the SBFD and non-SBFD time slot / symbol may not be referenceable because the antenna resources configured by the network node supporting the SBFD technology for uplink and downlink on the SBFD time unit are different from those configured on the normal TDD time unit. The method in turn avoids additional measurement behavior and time caused by the network to obtain referenceable measurement result, or by the UE due to measurement not satisfying the measurement event triggering threshold, and save the measurement and communication resources, causing the network in the deployment of SBFD configure and schedule the UE faster through more reliable measurement report, improving the overall capacity and performance of the network.

[0115] Optionally, after steps 411 and 412, the base station may add measurement restriction to the UE, that is, the base station may configure corresponding measurement restriction for the UE based on the first information and the second information.

[0116] Optionally, the measurement restriction may be implemented by the base station configuring the UE with only objects located on the non-SBFD time slot / symbol (or similarly, called objects not located on the SBFD time slot / symbol) when configuring the UE with measurement objects, or similarly, by configuring the UE with only measurement resources not overlapping with the SBFD time slot / symbol. Through the implementation, the base station restricts the UE to measure only on the non-SBFD time slot (or symbol), thus improving the accuracy of the measurement result. The measurement restriction may also be implemented by configuring the measurement objects or resources in the opposite manner to the above example, that is, configuring the measurement objects or resources to be all located on or fully overlapping with the SBFD time slot / symbol.

[0117] Optionally, the measurement restriction may also be implemented by the UE by avoiding (or dropping) its measurement of objects located on the SBFD time slot / symbol or avoiding (or dropping) its measurement resources overlapping or partially overlapping with the SBFD time slot / symbol based on the first information and the second information. A representation of the implementation may be: when the measurement objects are partially or fully overlapping with the SBFD time slot / symbol, the UE is not required to receive the corresponding configured measurement objects and performs corresponding configured measurement. A possible representation may also be: when the measurement objects are partially or fully overlapping with the SBFD time slot / symbol, the UE does not require the accuracy of the measurement result for the measurement objects.

[0118] In such implementation, after the UE avoids (or drops) some measurement in the above manner, its required measurement time or evaluation time based on the measurement should be extended accordingly. Extension may be achieved by designing an amplification factor (or multiplier) and applying the amplification factor (or multiplier) to the time required for the original measurement.

[0119] For example, the amplification factor may be designed by the following calculation method. When the configured measurement objects or measurement resources do not overlap with any other measurement configurations (such as measurement interval, layer 3 measurement, etc.), set the number of the measurement objects or measurement resources (such as SSB, RLM-RS, CBD-RS, etc.) configured for the UE not overlapping with the SBFD time slot / symbol be N_sbfdNotOverlap, and set the total number of the measurement objects or measurement resources configured for the UE be N_total, then the amplification factor is N_total / N_sbfdNotOverlap. When the configured measurement objects overlap or partially overlap with other measurement configurations, the number in the above N_sbfdNotOverlap needs to further consider the time period of other measurement configurations, and available measurement resources are calculated according to the overlap of the configured measurement objects and other measurement configurations involved, to amplify the original measurement time to obtain enough measurement times. For example, when the measurement object is configured as SSB, its period is T_SSB, and at this time, the UE is also configured with a measurement interval with a period of T_GAP. If the SSB partially overlaps with the measurement interval at this time, and the measurement interval does not overlap with the SBFD time slot, the amplification factor required for the original measurement time may be . If remaining measurement configuration (such as the measurement interval in the example) fully overlaps with the SBFD time slot, the amplification factor may be . If the remaining measurement configuration (such as the measurement interval in the example) partially overlaps with the SBFD time slot, in order to satisfy enough measurement, the amplification factor may be obtained by the followings: taking the ratio P1 = of the number (for example, N_sbfdOverlap) of measurement objects overlapping with the SBFD time slot and the total number of available measurement objects, and the ratio P2= of the measurement object period and measurement interval period, using the smaller one of P1 and P2 to calculate a scaling factor, and scaling the measurement time accordingly with the calculated scaling factor to obtain a long enough measurement time and ensuring that the measurement under the assumption is performed with enough time. In this way, the scaling factor under the assumption may be . For the design of the measurement time scaling factors in case of overlapping, partially overlapping or not overlapping with other measurement configurations, the scaling logic on which the measurement time is based on is the combination and inference in above examples, and is not exhaustive herein.

[0120] In such implementation, optionally, the UE may additionally consider the implementation of using the third information and the first condition, that is, the UE may apply the first condition based on the third information, and then avoid (or drop) the measurement result satisfying the first condition.

[0121] Such measurement restriction may also be embodied by applying new restriction on application range of existing measurement requirement. For the measurement and evaluation time requirement for the UE, when the UE is configured with SBFD by the network, it is only applicable when the configured measurement objects are only on the normal TDD time slot / symbol (or the non-SBFD time slot / symbol).

[0122] In the disclosure, the measurement objects include but are not limited to SSB, CSI-RS, etc. In the disclosure, measurement includes but is not limited to L1-RSRP measurement, SSB or CSI-RS based RLM measurement, BFD measurement, CBD measurement, etc.

[0123] By adding the measurement restriction for the UE being configured to perform measurement on the non-SBFD time slot / symbol, the accuracy of the measurement result of the UE in SBFD deployment is improved and the reliability of network for configuration and scheduling based on the measurement report is enhanced. A method for enhancing the measurement accuracy of the UE in the SBFD network is described below.

[0124] FIG. 4b illustrates a method 420 for performing measurement configuration on a UE (UE1) in a network supporting SBFD according to embodiments of the present disclosure.

[0125] The method 420 includes: at 421, the UE1 reports, to a base station, information indicating that it is a UE with SBFD aware capability and / or a UE supporting SBFD measurement behavior enhancement via signaling such as UE capability, that is, the above first information, wherein information of SBFD aware and information of supporting the SBFD measurement behavior enhancement may be indicated independently by two information carriers (such as information elements), or may be indicated in combination by one information therein implicitly indicating two capabilities (for example, when the UE1 reports the information of SBFD aware, it is implied that the UE1 reports, to the base station, the information of supporting the SBFD measurement behavior enhancement). Optionally, the first information may be reported by adding a new information element in UECapabilityInformation message. Optionally, the UE reporting, to the base station, the first information is in response to the UE receiving, from the base station, information for inquiring about the UE capability, and the name of the information for inquiring about UE capability is not limited herein.

[0126] At 422, the UE1 receives, from the base station, second information indicating SBFD uplink and downlink time slot and / or symbol configuration in the network.

[0127] At 423, the UE1 receives, from the base station, fourth information for configuring measurement. In the disclosure, "fourth information" may be used interchangeably with "fourth measurement configuration information", and the name of the fourth information is not limited herein.

[0128] The fourth information may include / indicate / be associated with / be configured with at least one of the followings:

[0129] - measurement resources: the measurement resources configured by the base station may be SINR resources (e.g. SBFD_intra-SINR) and reference signal strength indicator (RSSI) resources (e.g. SBFD_intra-RSSI). The measurement resources include a certain number of physical resource blocks (PRBs) in the sub-band where the UE1 is currently located or in the active bandwidth part (BWP). The number of the configured PRBs may be determined by giving position of starting PRB and ending PRB. Optionally, the measurement resources may be configured with a certain number of symbol resources.

[0130] - reporting type: the measurement reporting type configured by the base station may be event triggering.

[0131] - measurement event: if the base station configures event triggering, a corresponding threshold should be configured. For example, when the measurement resources are SBFD_intra-RSSI, the base station may configure to report when the measured SBFD_intra-RSSI is greater than a fixed value, or when change of the measured SBFD_intra-RSSI is greater than a fixed value.

[0132] The fourth information is for configuring the UE1 to measure and report interference from a neighboring UE2 transmitting uplink on the same carrier.

[0133] At 424, the UE1 performs measurement based on the fourth information and reports the measurement result. In the disclosure, the measurement result obtained by performing the measurement based on the fourth information may be called the fourth measurement result, and specific name is not limited herein.

[0134] At 425, the UE1 receives, from the base station, a measurement scheduling restriction, which includes measurement resources. In the disclosure, "measurement scheduling restriction" may be used interchangeably with "fifth measurement configuration"

[0135] At 426, the UE1 performs measurement based on the fifth measurement configuration information. Here, a representation of the measurement scheduling restriction is to make the UE1 communicating on a downlink sub-band not expect to receive physical uplink control channel (PUCCH), physical uplink shared channel (PUSCH) or sounding reference signal (SRS), etc., or energy thereof from UE2 communicating on neighboring uplink sub-band in the same carrier at the time unit where measurement resources configured for the UE1 are located. The UE2 is the UE transmitting uplink in a neighboring uplink sub-band in the same carrier in the cell at the time instance at which the measurement event included in UE1's fifth information is triggered.

[0136] Another representation of the above measurement scheduling restriction may also be that the UE1 does not expect the time unit where the measurement resources configured for the UE1 are partially or fully overlapping with the time unit where uplink signals such as PUCCH, PUSCH, SRS, etc. with which the UE2 communicating on the neighboring sub-band in the same carrier is scheduled are located.

[0137] In the disclosure, the neighboring uplink sub-band where the UE2 is located is an uplink sub-band in the same carrier (or in intra-frequency) as the downlink sub-band where the UE1 is located. The neighboring uplink sub-band may partially overlap, fully overlap or fully not overlap with the downlink sub-band where the UE1 is located. When it is not fully overlap with the downlink sub-band where the UE1 is located, it may also have a certain frequency interval from the downlink sub-band where the UE1 is located instead of being directly neighboring.

[0138] In the SBFD network, the above method 420 is for the case that different users are allowed to transmit and receive on different uplink or downlink bandwidths by allocating the current carrier bandwidth to sub-band bandwidth for uplink and sub-band bandwidth for downlink on the same SBFD time slot / symbol, and more specifically, for the case that the UE (hereinafter referred as UE1) performing downlink data reception or downlink channel measurement on a downlink sub-band in a cell of the network subjects to interference from a UE in the same cell performing uplink transmission on a neighboring uplink sub-band in the same carrier.

[0139] Through the above method 420, the UE1 may monitor the interference level of other UEs in the same cell simultaneously transmitting uplink within the downlink channel bandwidth configured for the UE1. When interference occurs, this method may provide, to the base station, relevant information through measurement report, and the scheduling restriction is applied by the base station on the measurement of the UE1 and the uplink transmission of the UE2, in order to reduce the interference to the UE1 from the UE2 during measurement, improve the accuracy of the measurement, save measurement resources and further improve the performance of the network for radio resource management, the overall capacity of the network and the reliability of scheduling configuration based on the measurement.

[0140] When a type of UE reports to the network / base station that it is capable of performing Layer 1 Cross-link interference measurement (L1 CLI measurement) via eighth information, the fourth information in the above step 423 may also configure such UE to perform Layer 1 measurement.

[0141] The eighth information here may be reported via UE Capability Information (UECapabilityInformation) in response to UE capability query information transmitted by the network, and the eighth information indicating the capability may include but not limited to one or more of the followings modes:

[0142] - supporting L1 CLI measurement;

[0143] - not supporting L1 CLI measurement;

[0144] - supporting single L1 CLI measurement;

[0145] - not supporting single L1 CLI measurement;

[0146] - supporting multiple L1 CLI measurements;

[0147] - not supporting multiple L1 CLI measurements;

[0148] - supporting aperiodic reporting of L1 CLI measurement;

[0149] - not supporting aperiodic reporting of L1 CLI measurement, etc.

[0150] In the above modes, when the UE reports one of the capabilities, it may also implicitly indicate that the UE supports corresponding other capabilities. For example, when supporting L1 CLI measurement means supporting multiple L1 CLI measurements by default, reporting the capability of supporting L1 CLI measurement may indicate that the UE supports L1 CLI measurement and L1 CLI multiple measurements. In the example, when supporting L1 CLI measurement means supporting multiple L1 CLI measurements by default, whether the UE supports single L1 CLI measurement may also be determined by whether the UE reports supporting or not supporting L1 CLI measurement, that is, when the capability of supporting single L1 CLI measurement is reported or the capability of not supporting L1 CLI measurement is not reported, it means that the UE may support both single L1 CLI measurement and multiple L1 CLI measurements; however, when the capability of supporting single L1 CLI measurement is not reported or the capability of not supporting single L1 CLI measurement is reported, it means that the UE only supports multiple L1 CLI measurements.

[0151] For example, when the UE reports the capability of supporting aperiodic reporting of L1 CLI measurement, it also implies that the UE should support the capability of single L1 CLI measurement. At this time, reporting the capability of supporting or not supporting aperiodic reporting of L1 CLI measurement may also imply that the UE supports or does not support single LI CLI measurement or multiple LI CLI measurements.

[0152] The capability of single L1 CLI measurement here may also be represented as the capability of single-sample L1 CLI measurement or the capability of fast L1 CLI measurement, which is intended to indicate that the required L1 CLI measurement may be completed in less measurement samples, and its name is not limited herein.

[0153] The reporting of the UE capability here may also be implicitly embodied. For example, for the UE supporting SBFD enhancement described in the aforementioned method in the application, if the UE supports L1 CLI measurement by default, or even supports single L1 CLI measurement by default, the capability indication provided by the eighth information may be replaced by the aforementioned first information indicating whether the UE supports SBFD enhancement.

[0154] After the UE explicitly or implicitly reports its capability for single L1 CLI measurement via the above eighth information, the network configures L1 CLI measurement for the UE via the following ninth information.

[0155] At this time, the fourth information is information for configuring L1 CLI measurement, and the fourth information may also include / indicate / associate with / configure the ninth information associated with L1 CLI measurement configuration. The ninth information may include one or more of the followings:

[0156] - measurement resources of channel sounding reference signal (SRS) reference signal received power (RSRP) (SRS-RSRP);

[0157] - measurement resources of cross-link interference (CLI) reference signal strength indicator (RSSI) (CLI-RSSI);

[0158] - indicating the cell ID to which the UE2 causing interference belongs and corresponding to the measurement resources of channel sounding reference signal (SRS) reference signal received power (RSRP);

[0159] - indicating whether the UE1 configured with L1 CLI measurement and the measured UE2 causing interference belong to the same cell;

[0160] - indicating whether the UE1 configured with L1 CLI measurement and the measured UE2 causing interference belong to different cells which are co-located or co-sited;

[0161] - indicating whether the UE1 configured with L1 CLI measurement and the measured UE2 causing interference belong to different cells which are cell phase synchronized or cell phase well synchronized;

[0162] - indicating whether the configured L1 CLI measurement is single measurement or single-sample measurement;

[0163] - indicating whether the configured L1 CLI measurement is multiple measurements or multi-sample measurement.

[0164] In the above mode, when the ninth information indicates that the cell ID to which the UE2 causing interference belongs and corresponding to the measurement resources of channel sounding reference signal (SRS) reference signal received power (RSRP) is the same as the cell ID of the UE1 currently performing L1 CLI; or indicates that the UE1 configured with L1 CLI measurement and the measured UE2 causing interference belong to the same cell; or indicates that the UE1 configured with L1 CLI measurement and the measured UE2 causing interference belong to different cells which are co-located or co-sited; or indicates that the UE1 configured with L1 CLI measurement and the measured UE2 causing interference belong to different cells which are cell phase synchronized or cell phase well synchronized; or indicate that the configured L1 CLI measurement is single measurement or single-sample measurement; or indicates that the configured L1 CLI measurement is multiple measurements or multi-sample measurement, it means configuring the UE1 to perform single L1 CLI measurement in the application. Where the single L1 CLI measurement may be the default configuration, and at this time, it may also be configured implicitly, that is, the ninth information transmitted by the network at this time may not contain the above information, but it is implicitly indicated as single L1 CLI measurement when the second information transmitted indicating the SBFD network.

[0165] In contrast, when the ninth information indicates that the cell ID to which the UE2 causing interference belongs and corresponding to the measurement resources of channel sounding reference signal (SRS) reference signal received power (RSRP) is not the same as the cell ID of the UE1 currently performing L1 CLI; or indicates that the UE1 configured with L1 CLI measurement and the measured UE2 causing interference does not belong to the same cell; or indicates that the UE1 configured with L1 CLI measurement and the measured UE2 causing interference does not belong to different cells which are co-located or co-sited; or indicates that the UE1 configured with L1 CLI measurement and the measured UE2 causing interference does not belong to different cells which are cell phase synchronized or cell phase well synchronized; or indicate that the configured L1 CLI measurement is not single measurement or single-sample measurement; or indicates that the configured L1 CLI measurement is multiple measurements or multi-sample measurement, it means configuring the UE1 to perform multiple L1 CLI measurements in the application,. Where the multiple L1 CLI measurements may be the default configuration, and at this time, it may also be configured implicitly, that is, the ninth information transmitted by the network at this time may not contain the above information, but it is implicitly indicated as multiple L1 CLI measurements when the second information transmitted indicating the SBFD network.

[0166] The above indication may be indicated by agreeing on the specific value of a specific bit in the ninth information or the fourth information. For example, when the specific bit is agreed to be 0, it means to perform single L1 CLI measurement; similarly, when the bit is agreed to be 1, it means to perform multiple L1 CLI measurements. Similar implementations are not exhaustive here.

[0167] The single L1 CLI measurement here may also be represented as single-sample L1 CLI measurement or fast L1 CLI measurement, which is intended to indicate that the required L1 CLI measurement may be completed in less measurement samples, and its name is not limited herein.

[0168] The multiple L1 CLI measurements here may also be represented as multi-sample L1 CLI measurements or conventional L1 CLI measurements, which are intended to indicate that the required L1 CLI measurements may not be completed in less measurement samples, and its name is not limited herein.

[0169] At this time, the fourth information may be transmitted by the base station to the UE via channel state information configuration information (CSI-config), or may be transmitted in downlink control information (DCI) by using other information such as CSI request, which is not limited in the application.

[0170] When the UE is configured by the network as described above, the UE should perform corresponding Layer-1 measurement, such as Layer-1 channel sounding reference signal reference signal received power (L1-SRS-RSRP) measurement or Layer-1 cross-link interference reference signal strength indicator (L1-CLI-RSSI) measurement, on the configured measurement resources, such as SRS-RSRP or CLI-RSSI, etc.

[0171] In this scenario, when the UE measures L1-SRS-RSRP or L1-CLI-RSSI in the configured L1 CLI resources, there is a time interval between the downlink reference timing of the UE1 and the uplink transmission timing of the UE2 causing cross-link interference, so when the UE1 performs the above configured measurement, a time offset (first offset) should be applied to the downlink reference timing of the UE1 to complete the measurement.

[0172] The first offset is determined by one or more of the followings:

[0173] - configured as single L1 CLI measurement;

[0174] - configured as multiple L1 CLI measurements;

[0175] - basic time unit (Tc) is 0.509 nanoseconds;

[0176] - timing advance offset (NTA);

[0177] - distance between the base station serving the UE1 and the base station serving the UE2;

[0178] - transmission delay interval caused by the distance between the base station serving the UE1 and the base station serving the UE2;

[0179] - phase difference interval between the base station serving the UE1 and the base station serving the UE2.

[0180] - 1 / N of cyclic prefix (CP), where N is an integer greater than or equal to 2;

[0181] - a value less than 1 / N of the cyclic prefix (CP), where N is an integer greater than or equal to 2;

[0182] - a value that has a mapping relationship with the value of subcarrier spacing (SCS).

[0183] The determination for the first offset is that when the base station indicates that the current L1 CLI measurement is single L1 CLI measurement by configuration described above, the first offset may take a smaller preset value. This condition may also be implicitly determined by other means, for example, when the distance between the base station serving the UE1 and the base station serving the UE2, or the transmission delay interval caused by the distance between the base station serving the UE1 and the base station serving the UE2, or the phase difference interval between the base station serving the UE1 and the base station serving the UE2 is less than an agreed threshold, it should be understood as equivalent to condition that the indicated two base stations are co-sited or phase synchronized in the ninth information, that is, it indicates that single L1 CLI measurement is applicable, that is, the first offset may be determined to take the smaller preset value under such condition.

[0184] Similarly, when the above condition is opposite, that is, when the base station indicates that the currently configured L1 CLI is multiple measurements, the first offset may take a larger preset value under such condition.

[0185] In this scenario, when the UE measures L1-SRS-RSRP or L1-CLI-RSSI in the configured L1 CLI resources, it should complete the measurement within a third time. The third time is determined by one or more of the followings:

[0186] - configured as single L1 CLI measurement;

[0187] - configured as multiple L1 CLI measurements.

[0188] The determination for the third time is that when the base station indicates that the current L1 CLI measurement is single L1 CLI measurement by configuration described above, the third time may be a single measurement period of the configured measurement resource, such as the measurement period of L1-SRS-RSRP or the measurement period of L1-CLI-RSSI. The determination for the third time may also be that when the first offset is the smaller value described above, according to the above scheme, it may be understood that it is currently single L1 CLI measurement, and the third time may be a single measurement period of the configured measurement resource.

[0189] Similarly, when the condition is opposite, at this time, the current L1 CLI is multiple measurements, then the third time may be a positive integer multiple of the single measurement period of the configured measurement resource.

[0190] The third time may also be configured in combination with discontinuous reception (DRX) cycle. At this time, one value of the third time may be the larger value after comparing corresponding periods for the single measurement or multiple measurements with the configured DRX cycle under corresponding conditions.

[0191] In addition, when the base station indicates that the current L1 CLI measurement is single L1 CLI measurement, if the configured measurement resource (such as L1-SRS, etc.) partially or fully overlap with other configured SSB-based measurement timing configuration (SMTC), SSB or CSI-RS time and frequency domain resources, the above third time requirement may not be satisfied.

[0192] Meanwhile, when the base station indicates that the current L1 CLI measurement is single L1 CLI measurement by configuration described above, the UE is not expected to receive a physical downlink control channel (PDCCH) or a physical downlink shared channel (PDSCH) on the orthogonal frequency-division multiplexing (OFDM) symbol for L1 CLI measurement and previous X symbols due to resource conflict, depending on first capability of the UE.

[0193] Wherein the first capability is whether the UE supports the capability of simultaneous transmission and reception on different frequency domain resources.

[0194] Wherein the number of symbols described by X may be determined by one or more of the followings:

[0195] - whether the UE is currently configured to perform single L1 CLI measurement;

[0196] - the first offset;

[0197] - SCS;

[0198] - frequency range (FR)

[0199] The determination for X is:

[0200] - if the first offset of the L1 CLI measurement with which the UE is currently configured is less than 1 / 2 times CP, then X may be taken as 0.

[0201] - if the first offset of the L1 CLI measurement with which the UE is currently configured is greater than 1 / 2 times CP, and the first offset is less than a OFDM symbol length, then X may be taken as 1.

[0202] - if the first offset of the L1 CLI measurement with which the UE is currently configured is greater than an OFDM symbol length and less than two OFDM symbol lengths, then X may be taken as 2.

[0203] In some representations of the determination for X, the value of X may be determined by implicit comparison with the above-described 1 / 2 times CP or OFDM symbol length(s) depending on the first offset of the L1 CLI measurement with which the UE is currently configured, without mentioning comparison between specific values.

[0204] Whether the UE is currently configured to perform single L1 CLI or multiple L1 CLI may be explicitly or implicitly indicated in the aforementioned scheme, and will not be repeated here.

[0205] Applying this scheme, when performing L1 CLI measurement, the timing offset of the L1 CLI measurement required by the UE is lower when the UE that supports single L1 CLI measurement and when the serving base stations are the same base station or near base stations or well synchronized base stations, thus its measurement accuracy is higher, and the required measurement times or time may be reduced accordingly. After applying the scheme, for the UE in this scenario, its time for L1 CLI measurement may be reduced and the network efficiency may be improved. For other scenarios, or for the UE not supporting single L1 CLI measurement, it may perform multiple L1 CLI measurements to ensure the accuracy of its measurement.

[0206] One representation of the above scheme is as follows.

[0207] For L1-SRS-RSRP measurement reporting time:

[0208] When configured by the network, the UE should be able to perform L1-SRS-RSRP measurement on L1-SRS or SRS resources configured for L1-SRS-RSRP measurement. For FR1 and FR2, the UE should be able to report the measured L1-SRS-RSRP in the third time. Table 4 below illustrates L1-SRS-RSRP measurement time.

[0209]

[0210] K and corresponding method explained in Note 2 for determining its value in the above Table is a representation of determining the value of the third time based on whether the current measurement is single L1 CLI measurement described above. The second condition described in Note 2 in the example may be understood here as that when the measurement is single L1 CLI measurement, K takes 1, that is, the measurement time required here is shorter. The determination for K=3 by the second condition described in Note 2 is that K=3 under other cases, which is a representation of K=3 by default configuration described above. Below are some possible descriptions:

[0211] - K=1 when the UE is configured to perform single-sample L1 CLI (L1-SRS-RSRP) measurement; otherwise K=3;

[0212] - K=1 when the UE is configured to perform fast L1-SRS-RSRP measurement; otherwise K=3;

[0213] - K=3 by default, and K=1 when the UE is configured to perform intra-cell L1-SRS-RSRP measurement;

[0214] - K=3 by default, and K=1 when the UE is configured to perform cell phase synchronized L1-SRS-RSRP measurement;

[0215] - K=1 when the UE is configured to perform co-located / co-sited cell L1-SRS-RSRP measurement, otherwise K=3;

[0216] - K=1 when the UE is configured to perform intra-cell L1-SRS-RSRP measurement and the UE reports the capability of supporting single L1 CLI measurement, otherwise K=3.

[0217] The specific representation of the second condition is intended to describe whether the current measurement in the aforementioned scheme is single L1 CLI measurement, therefore, logic and content for determining the third time in the aforementioned description may equally apply to the representation of the second condition. Here, various possibilities will not be repeated.

[0218] Similarly, the second condition may also be used in reverse, that is, when the second condition is satisfied, K=3; otherwise K=1.

[0219] In some representations, it may be represented by directly taking the corresponding value as 1 or 3 without using K, and the representation of the second condition may be embodied in the context of the corresponding value. The following are embodiments when different situations are divided into two Tables (Table 5 and Table 6). Table 5 and Table 6 below illustrate L1-SRS-RSRP measurement times, respectively.

[0220]

[0221]

[0222] In the above Table 5 and Table 6, Table 5 is a method in which K=3 is the default configuration in the example described above, and its value 3 is directly applied in the Table, while Table 6 is a method in which K=1 is directly applied in the Table when the second condition is satisfied in the example described above.

[0223] For measurement timing offset Y of L1-SRS-RSRP:

[0224] When the UE measures L1-SRS-RSRP or L1-CLI-RSSI in the configured L1 CLI resources, a time offset relative to its downlink reference timing in the serving cell should be applied. The value of the time offset depends on the UE implementation and should be at least TC Х NTA_offset and not exceed Tc*NTA_offset+Y.

[0225] The method of obtaining the value of Y is the same as that of the first offset. The condition corresponding to the method of obtaining the value of Y also depends on the condition corresponding to the first offset in the scheme, and may also be described as the second condition in the example described above. Here are some possible descriptions:

[0226] - when the UE is configured to perform single-sample L1 CLI (L1-SRS-RSRP) measurement, Y is CP / 2 or CP / 3 or CP / 4, etc.;

[0227] - when the UE is configured to perform single-sample L1 CLI (L1-SRS-RSRP) measurement, Y is a preset value less than CP / 2 or CP / 3 or CP / 4, such as 2.5 microseconds (for example, a value less than CP / 2=2.6 microseconds) or 1.4 microseconds (for example, less than CP / 2 = 4) for FR1 and SCS=15kHz.

[0228] In the above example, single-sample L1 CLI may be interchanged with single L1 CLI, fast L1 CLI, intra-cell L1 CLI, co-sited L1 CLI, cell phase synchronized L1 CLI, etc., as described in the specification, corresponding processes thereof in the scheme are the same. Here, it is not exhaustive to enumerate all possible representations.

[0229] In the representation of this example, specific values are only examples that conform to the method of obtaining the value, and the specific values are not limited.

[0230] The measurement timing offset may also be embodied in the measurement accuracy requirement for the configured L1 CLI, that is, when the measurement timing offset Y is less than a certain value, it means that the measurement result of the L1 CLI is reliable, that is, the L1 CLI satisfies the accuracy requirement.

[0231] Its representation may be:

[0232] the L1-SRS-RSRP measurement reported by the UE shall fulfil the accuracy requirements, provided the following conditions are met. For the time difference between UE's DL reference timing in the serving cell and SRS arrival time is no longer than first offset, the condition is satisfied.

[0233] Wherein for the first offset and Y included in the first offset, the above-mentioned various conditional representations and their corresponding methods of determining the value are applicable.

[0234] In the SBFD network, different users may be allocated to different sub-bands in the current carrier for uplink transmission and downlink reception at the same time. Depending on UE implementation, the UE may configure its devices such as antenna, radio frequency, baseband etc. according to the sub-band bandwidth and frequency position allocated by the base station for the UE to optimize signal quality of its communication within the sub-band. A method for enhancing the switching process of a UE between sub-bands is provided below.

[0235] FIG. 4c illustrates a method 430 for a UE to perform sub-band switching in a network supporting SBFD according to embodiments of the present disclosure.

[0236] The method 430 includes, at 431, the UE reports, to a base station, sixth information indicating that it has the capability of SBFD sub-band switching via signaling such as UE capability. Optionally, the sixth information includes information associated with the capabilities of the UE. The name of the sixth information is not limited herein.

[0237] Here, the capability of sub-band switching indicated by the sixth information may be represented by a UE type or the UE capability, or represented by a specific time duration required. The sixth information may be reported by adding a new information element in the UECapabilityInformation message. The sixth information may also be reported via other message indications.

[0238] Here, if the capability indicated by the sixth information is represented by the UE type, and the capability is described by fast and slow, a possible mapping relationship is shown in Table 7 below:

[0239]

[0240] Here, the representation of the sixth information indication may also be represented in more detail by one or more subdivided capabilities such as whether the UE needs radio frequency reconfiguration time, whether the UE needs baseband reconfiguration time, and whether the UE needs automatic gain control adjustment time, etc. When represented in such manner, the above sub-band switching time may be divided into a combination of one or more subdivided times such as radio frequency reconfiguration time, baseband reconfiguration time, automatic gain control adjustment time, etc.

[0241] Here, the indication of the sixth information may also be indicated by whether the UE transmits the sixth information. A representation of such manner is that when the UE transmits the sixth information indicating its capability or certain corresponding subdivided capabilities, the UE needs additional interruption time or certain subdivided times corresponding to the subdivided capabilities when performing sub-band switching. Accordingly, when the UE does not transmit the sixth information indicating its capability or certain corresponding subdivided capabilities, the UE does not need additional interruption time or certain subdivided times corresponding to the subdivided capabilities when performing sub-band switching. Correspondence in this representation may also be an opposite of that in the example, or any other possible representations.

[0242] At 432, the base station indicates the UE to perform sub-band switching (e.g., explicit indication) or indicates the UE to perform uplink transmission or downlink reception on a new sub-band (e.g., implicit indication) via indication information.

[0243] The indication information here may be based on a Radio Resource Control (RRC) message, such as RRC reconfiguration information; may also be based on Downlink Control Information (DCI); may also be based on a timer. Here, the indication information may be referred as seventh information. The name of the seventh information is not limited herein.

[0244] At 433, the UE performs and completes the SBFD sub-band switching within first time after receiving the indication information (the seventh information) at step 432, wherein the first time is the interruption time of sub-band switching, which is determined based on at least one of the time required for automatic gain control adjustment, time required for radio frequency readjustment, time required for baseband reconfiguration, radio resource control RRC processing time, time required for sub-band switching and the UE capability.

[0245] At 434, after the first time, for example, uplink and downlink transmission may be performed on a first time slot after the first time, for example, transmission and reception may be performed on a new sub-band, wherein the UE completes the SBFD sub-band switching within the first time. This will be described below in combination with various specific measurement processes.

[0246] Optionally, the method 430 may include steps of receiving, from the base station, the first information and the second information as described with reference to FIGs. 4a and 4b.

[0247] Through method 430, the base station may configure different sub-band switching interruption times for UEs with different sub-band switching capabilities, such that the network does not need to configure the longest sub-band switching interruption time for all UEs. For different adjustment times required by the UEs, including but not limited to adjustment time of radio frequency (RF), bandwidth of baseband (BB), reconfiguration time of local oscillator (LO), adjustment time of automatic gain control (AGC), etc., the base station may determine the required time according to corresponding information in the method when sub-band switching occurs. This method ensures connection of UEs that need additional sub-band switching time, such that it will not be scheduled by the network with uplink or downlink too early or too late when performing sub-band switching, causing waste of communication resources, while reduces the interruption time of UEs that do not need additional sub-band switching time, improves the connection opportunities and communication resources of some UEs in the network, and further improves resource utilization of the network and network capacity.

[0248] In the application, the method 410 shown in FIG. 4a and the method 430 shown in FIG. 4c may be implemented separately or in combination.

[0249] Above methods are described in detail below in connection with various measurement related processes.

[0250] In the process of Radio Link Monitor (RLM), a user equipment (UE) should monitor downlink radio link quality based on reference signals configured as RLM reference signal (RLM-RS) resources, in order to detect the downlink radio link quality of the current serving cell. The configured RLM-RS resources can be all SSBs, or all channel-state information reference signals (CSI-RS), or a mix of SSBs and CSI-RSs. The UE does not need to perform RLM outside the active downlink bandwidth part (DL BWP).

[0251] On each RLM-RS resource, the UE should estimate the downlink radio link quality and compare it with thresholds Qout and Qin for the purpose of monitoring the downlink radio link quality of the cell. The threshold Qout is defined as the level at which the downlink radio link cannot be reliably received, and the threshold Qin is defined as the level at which the downlink radio link quality can be received with significantly higher reliability than at Qout.

[0252] Wherein for SSB based radio link monitoring:

[0253] The UE should be able to evaluate whether the downlink radio link quality on the configured RLM-RS resources estimated over the last TEvaluate_out_SSB millisecond period becomes worse than the threshold Qout_SSB within TEvaluate_out_SSB millisecond evaluation period.

[0254] The UE should be able to evaluate whether the downlink radio link quality on the configured RLM-RS resources estimated over the last TEvaluate_in_SSB millisecond period becomes better than the threshold Qin_SSB within TEvaluate_in_SSB millisecond evaluation period.

[0255] Wherein Qout_SSB and Qin_SSB are Qout and Qin defined in the scenario of the SSB based radio link monitoring, respectively.

[0256] For FR2, definitions of the above evaluation times (also referred as evaluation periods in the disclosure) TEvaluate_out_SSB and TEvaluate_in_SSB are shown in Table 8 below.

[0257]

[0258]

[0259] In Table 8, for the factor P in the evaluation times, when the aforementioned method of adding measurement restriction is implemented in an SBFD network, the factor P may be designed by the following calculation method. When the measurement objects SSBs of the RLM does not overlap with any other measurement configurations (such as measurement interval, layer 3 measurement, etc.), set the number of SSBs for RLM measurement configured for the UE not overlapping with the SBFD time slot / symbol be N_sbfdNotOverlap, and set the total number of SSBs for RLM measurement configured for the UE be N_total, then the factor P is N_total / N_sbfdNotOverlap. When SSBs for RLM measurement overlap or partially overlap with other measurement configurations, the number in the above N_sbfdNotOverlap needs to further consider the time period of other measurement configurations, and available measurement resources are calculated according to the overlap of SSBs for RLM measurement and other measurement configurations involved, to amplify the original measurement time to obtain enough measurement times. For example, when the measurement object configuration is SSB, its period is T_SSB, and at this time, the UE is also configured with a measurement interval with a period of T_GAP. If the SSB partially overlaps with the measurement interval at this time, and the measurement interval does not overlap with the SBFD time slot, the amplification factor required for the original measurement time may be . If remaining measurement configuration (such as the measurement interval in the example) completely overlaps with the SBFD time slot, the amplification factor may be . If the remaining measurement configuration (such as the measurement interval in the example) partially overlaps with the SBFD time slot, in order to satisfy enough measurement, the amplification factor may be obtained by the followings: taking the ratio P1 = of the number (for example, N_sbfdOverlap) of measurement objects overlapping with the SBFD time slot and the total number of available measurement objects, and the ratio P2= of the measurement object period and measurement interval period, using the smaller one of P1 and P2 to calculate the scaling factor, and scaling the measurement time accordingly with the calculated scaling factor to obtain a long enough measurement time and ensuring that the measurement under the assumption is performed with enough time. In this way, the scaling factor under the assumption may be . For the design of the measurement time scaling factors in case of overlapping, partially overlapping or not overlapping with other measurement configurations, the scaling logic on which the measurement time is based on is the combination and inference in above examples, and is not exhaustive herein.

[0260] Similarly, when RLM-RS is CSI-RS, the above measurement restriction representation and evaluation time factor are equally applicable, except that the introduced factor is applied on evaluation times TEvaluate_out_CSI-RS and TEvaluate_in_CSI-RS.

[0261] For measurement restriction of the SSB based RLM, when the above method of adding measurement restriction is implemented in an SBFD network, a representation of measurement restriction may be introduced. For example, for a UE in Frequency Range 1 (FR1) and Frequency Range 2 (FR2), the UE is not required to measure the SSB for RLM measurement when the SSB is on an SBFD symbol.

[0262] Similarly, for measurement restriction of the CSI-RS based RLM, the representation of the measurement restriction is, for example: for a UE in Frequency Range 1 (FR1) and Frequency Range 2 (FR2), the UE is not required to measure the CSI-RS for RLM measurement when the CSI-RS is on an SBFD symbol.

[0263] Similarly, for a link recovery procedure, the UE should evaluate the downlink radio link quality of the serving cell on the reference signal (RS) in a set specified in the specification to perform beam failure detection. RS resource configuration in the set can be periodic CSI-RS resources and / or SSBs. On each RS resource configuration in the set the UE should estimate the radio link quality and compare it with the threshold Qout_LR for the purpose of assessing the downlink radio link quality of the serving cell beams.

[0264] The threshold Qout_LR is defined as the level at which the downlink radio link of a given resource configuration cannot be reliably received, and should correspond to BLERout = 10% Block Error Rate (BLER) of a hypothetical physical downlink control channel (PDCCH) transmission.

[0265] Upon request, the UE should deliver a configuration indexes from the set , to higher layers, and the corresponding layer 1 reference signal received power (L1-RSRP) measurement according to requirements of the specification, provided that the measured L1-RSRP is equal to or better than the threshold Qin_LR, Qin_LR is configured by a higher layer parameter.

[0266] When the L1-RSRP measurement report occurs in the SBFD network and the above method for modifying the measurement result is applied, a possible representation is: depending on a request, the UE should transmit, to the higher layer, a configuration index in the set and corresponding layer 1 reference signal received power (L1-RSRP) measurement according to requirements of the specification, provided that the measured L1-RSRP is modified or amplified by sbfdMeasOffset, and the modified L1-RSRP result is equal to or better than the threshold Qin_LR, Qin_LR is configured by a higher layer parameter.

[0267] Wherein for SSB based beam failure detection (BFD), the UE should be able to evaluate whether the downlink radio link quality on SSB resources configured in the set estimated over the last TEvaluate_BFD_SSB millisecond period becomes worse than the threshold Qout_LR_SSB within the TEvaluate_BFD_SSB millisecond period, wherein Qout_LR_SSB is Qout_LR defined by the specification in the SSB based beam failure detection.

[0268] For FR2, evaluation time period TEvaluate_BFD_SSB is defined as shown in Table 9 below.

[0269]

[0270] In Table 9, for the factor P in the evaluation times, when the aforementioned method of adding measurement restriction is implemented in an SBFD network, the factor P may be designed by the following calculation method. When the measurement objects SSBs of the BFD does not overlap with any other measurement configurations (such as measurement interval, layer 3 measurement, etc.), set the number of SSBs for BFD measurement configured for the UE not overlapping with the SBFD time slot / symbol be N_sbfdNotOverlap, and set the total number of SSBs for BFD measurement configured for the UE be N_total, then the factor P is N_total / N_sbfdNotOverlap. When SSBs for BFD measurement overlap or partially overlap with other measurement configurations, the number in the above N_sbfdNotOverlap needs to further consider the time period of other measurement configurations, and available measurement resources are calculated according to the overlap of SSBs for BFD measurement and other measurement configurations involved, to amplify the original measurement time to obtain enough measurement times. For example, when the measurement object configuration is SSB, its period is T_SSB, and at this time, the UE is also configured with a measurement interval with a period of T_GAP. If the SSB partially overlaps with the measurement interval at this time, and the measurement interval does not overlap with the SBFD time slot, the amplification factor required for the original measurement time may be . If remaining measurement configuration (such as the measurement interval in the example) completely overlaps with the SBFD time slot, the amplification factor may be . If the remaining measurement configuration (such as the measurement interval in the example) partially overlaps with the SBFD time slot, in order to satisfy enough measurement, the amplification factor may be obtained by the followings: taking the ratio P1 = of the number (for example, N_sbfdOverlap) of measurement objects overlapping with the SBFD time slot and the total number of available measurement objects, and the ratio P2= of the measurement object period and measurement interval period, using the smaller one of P1 and P2 to calculate the scaling factor, and scaling the measurement time accordingly with the calculated scaling factor to obtain a long enough measurement time and ensuring that the measurement under the assumption is performed with enough time. In this way, the scaling factor under the assumption may be . For the design of the measurement time scaling factors in case of overlapping, partially overlapping or not overlapping with other measurement configurations, the scaling logic on which the measurement time is based on is the combination and inference in above examples, and is not exhaustive herein.

[0271] Similarly, when BFD-RS is CSI-RS, the above measurement restriction representation and evaluation time factor are equally applicable, except that the introduced factor is applied on evaluation time TEvaluate_BFD_CSI-RS.

[0272] For measurement restriction of the SSB based BFD, when the above method of adding measurement restriction is implemented in an SBFD network, a representation of measurement restriction may be introduced. For example, for a UE in Frequency Range 1 (FR1) and Frequency Range 2 (FR2), the UE is not required to measure the SSB for BFD measurement when the SSB is on an SBFD symbol.

[0273] Similarly, for measurement restriction of the CSI-RS based BFD, a possible representation is: for a UE in Frequency Range 1 (FR1) and Frequency Range 2 (FR2), the UE is not required to measure the CSI-RS for BFD measurement when the CSI-RS is on an SBFD symbol.

[0274] Similarly, for candidate beam detection (CBD), wherein for SSB based candidate beam detection (CBD): when required, the UE should be able to evaluate whether L1-RSRP measured on SSB resources configured in the set estimated over the last TEvaluate_CBD_SSB millisecond plus Tfine_rotation millisecond period becomes better than the threshold Qin_LR, wherein Tfine_rotation time period is the time for beam mechanical adjustment required by the UE using the mechanical scanning beam.

[0275] For FR2, definition of the time period TEvaluate_CBD_SSB is shown in Table 10 below.

[0276]

[0277] In Table 10, for the factor P in the evaluation times, when the aforementioned method of adding measurement restriction is implemented in an SBFD network, the factor P may be designed by the following calculation method. When the measurement objects SSBs of the CBD does not overlap with any other measurement configurations (such as measurement interval, layer 3 measurement, etc.), set the number of SSBs for CBD measurement configured for the UE not overlapping with the SBFD time slot / symbol be N_sbfdNotOverlap, and set the total number of SSBs for CBD measurement configured for the UE be N_total, then the factor P is N_total / N_sbfdNotOverlap. When SSBs for CBD measurement overlap or partially overlap with other measurement configurations, the number in the above N_sbfdNotOverlap needs to further consider the time period of other measurement configurations, and available measurement resources are calculated according to the overlap of SSBs for CBD measurement and other measurement configurations involved, to amplify the original measurement time to obtain enough measurement times. For example, when the measurement object configuration is SSB, its period is T_SSB, and at this time, the UE is also configured with a measurement interval with a period of T_GAP. If the SSB partially overlaps with the measurement interval at this time, and the measurement interval does not overlap with the SBFD time slot, the amplification factor required for the original measurement time may be . If remaining measurement configuration (such as the measurement interval in the example) completely overlaps with the SBFD time slot, the amplification factor may be . If the remaining measurement configuration (such as the measurement interval in the example) partially overlaps with the SBFD time slot, in order to satisfy enough measurement, the amplification factor may be obtained by the followings: taking the ratio P1 = of the number (for example, N_sbfdOverlap) of measurement objects overlapping with the SBFD time slot and the total number of available measurement objects, and the ratio P2= of the measurement object period and measurement interval period, using the smaller one of P1 and P2 to calculate the scaling factor, and scaling the measurement time accordingly with the calculated scaling factor to obtain a long enough measurement time and ensuring that the measurement under the assumption is performed with enough time. In this way, the scaling factor under the assumption may be . For the design of the measurement time scaling factors in case of overlapping, partially overlapping or not overlapping with other measurement configurations, the scaling logic on which the measurement time is based on is the combination and inference in above examples, and is not exhaustive herein.

[0278] Similarly, when CBD-RS is CSI-RS, the above measurement restriction representation and evaluation time factor are equally applicable, except that the introduced factor is applied on evaluation time TEvaluate_CBD_CSI-RS.

[0279] For measurement restriction of the SSB based CBD, when the above method of adding measurement restriction is implemented in an SBFD network, a representation of measurement restriction may be introduced. For example, for a UE in Frequency Range 1 (FR1) and Frequency Range 2 (FR2), the UE is not required to measure the SSB for CBD measurement when the SSB is on an SBFD symbol.

[0280] Similarly, for measurement restriction of the CSI-RS based CBD, a possible representation of the measurement restriction is: for a UE in Frequency Range 1 (FR1) and Frequency Range 2 (FR2), the UE is not required to measure the CSI-RS for CBD measurement when the CSI-RS is on an SBFD symbol.

[0281] Similarly, the method proposed in the application may be applied to other various measurement processes not described in the disclosure, and representations of applying the method proposed in the application to these measurement processes are similar to those of the above scenarios, and is not exhaustive herein.

[0282] Interruption time requirement for sub-band switching for the SBFD network is described below.

[0283] 1) DCI based and timer based sub-band switching delay

[0284] For DCI based sub-band switching, after the UE receives a sub-band switching request at downlink (or SBFD downlink) time slot n on the serving cell, the UE should be able to receive physical downlink shared channel (PDSCH) (for switching to downlink sub-band) or transmit physical uplink shared channel (PUSCH) (for switching to uplink sub-band) on a new sub-band at the first downlink (or SBFD downlink) or uplink (or SBFD uplink) time slot after the duration of T_SBFDswitchDelay which starts from the beginning of downlink (or SBFD downlink) time slot n where sub-band switching occurs.

[0285] For timer based sub-band switching, UE should start sub-band switching at downlink (or SBFD downlink) time slot n, where time slot n is the first time slot of the first downlink subframe (for FR1) or downlink half subframe (for FR2) immediately after the timer (such as sbfd-InactivityTimer) configured by high-level signaling expires on a serving cell. The UE should be able to receive PDSCH (for switching to downlink sub-band) or transmit PUSCH (for switching to uplink sub-band) on a new sub-band at the first downlink (or SBFD downlink) or uplink (or SBFD uplink) time slot after the duration of T_SBFDswitchDelay which starts from the beginning of downlink (or SBFD downlink) time slot n where sub-band switching occurs.

[0286] Referring to examples in Table 7, the above T_SBFDswitchDelay is represented by time duration as shown in Table 11 below:

[0287]

[0288] If the above T_SBFDswitchDelay is represented by the number of time slots, delay times in Table 11 may be converted into the number of time slots according to new radio (NR) time slot length, as shown in Table 12 below:

[0289]

[0290] Specific delay values, such as 5 ms and 600 ms, in the above example and time slot values converted in Table 12 according to these values are only exemplary. The specific values are not limited herein.

[0291] 2) RRC based sub-band switching delay

[0292] For RRC based sub-band switching, after UE receives RRC reconfiguration information carrying sub-band switching or modifying the current sub-band configuration at downlink (or SBFD downlink) time slot n on the serving cell, the UE shall be able to receive PDSCH (for switching to downlink sub-band) or transmit PUSCH (for switching to downlink sub-band) on a new sub-band at the first downlink (or SBFD downlink) or uplink (or SBFD uplink) time slot after which begins from the beginning of downlink (or SBFD downlink) time slot n where sub-band switching occurs, wherein downlink time slot n is the last time slot overlapping with the PDSCH containing the RRC command; NR time slot length is determined by the smaller subcarrier spacing (SCS) between the SCS before SBFD switching and the SCS after SBFD switching if the SBFD switching involves change of SCS; T_RRCProcessing is RRC processing delay; T_SBFDSwitchDelay is the time for the UE to perform SBFD sub-band switching, and the value of the delay may be based on the UE capability, as shown in Table 13 below.

[0293]

[0294] In the above example, for T_SBFDswitchDelay entry of time required for DCI based sub-band switching, timer based sub-band switching and RRC based sub-band switching, if representations of subdivided capabilities and corresponding subdivided times described above are applied, T_SBFDswitchDelay entry may be further consist of or replaced by the required subdivided times. Below is an example of a representation of the time consisting of the above three subdivided times:

[0295] T_SBFDswitchDelay = T_AGC + T_RF_retuning + T_BB_reconfig

[0296] Similarly, when three subdivided times directly replace T_SBFDswitchDelay in the above example, taking the interruption time of RRC based sub-band switching as an example, the required number of time slots may also be represented as:

[0297]

[0298] Wherein T_AGC in the above two examples is the automatic gain control adjustment time required by the UE when performing sub-band switching; T_RF_retuning is the radio frequency readjustment time required by the UE when performing sub-band switching; T_BB_reconfig is the baseband reconfiguration time required by UE when performing sub-band switching.
