METHOD AND TERMINAL AND BASE STATION IN WIRELESS COMMUNICATION SYSTEM

[0001] The disclosure relates to wireless communication technologies, and more particularly, to a method and apparatus for reporting of beam-related information 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.

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

Other embodiments of the wireless network 100 can be used without departing from the scope of the disclosure.

[0079] 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.

[0080] Depending on a type of the network, other well-known terms such as "base station (BS)" 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 example, the terms "terminal", "user equipment" and "UE" may be 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).

[0081] 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 implementations, 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.

[0082] 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.

[0083] 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 disclosure. In some implementations, one or more of gNB 101, gNB 102, and gNB 103 support codebook designs and structures for systems with 2D antenna arrays.

[0084] 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.

[0085] FIGS. 2A and 2B illustrate example wireless transmission and reception paths according to some embodiments of the 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 implementations, the reception path 250 is configured to support codebook designs and structures for systems with 2D antenna arrays as described in embodiments of the disclosure.

[0086] 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.

[0087] 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.

[0088] 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.

[0089] 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.

[0090] 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.

[0091] Furthermore, although described as using FFT and IFFT, this is only illustrative and should not be interpreted as limiting the scope of the 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.).

[0092] 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.

[0093] FIG. 3A illustrates an example UE 116 according to some embodiments of the 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 disclosure to any specific implementation of the UE.

[0094] 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.

[0095] 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).

[0096] 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.

[0097] 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.

[0098] 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 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.

[0099] 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).

[0100] 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 processor / controller 340 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.

[0101] In some implementations, two or more UEs 116 may communicate directly using one or more sidelink channels (for example, without using a base station as a medium for communication with each other). For example, the UE 116 may communicate using peer-to-peer (P2P) communication, device-to-device (D2D) communication, vehicle-to-everything (V2X) protocol (which, for example, may include vehicle-to-vehicle (V2V) protocol, vehicle-to-infrastructure (V2I) protocol, etc.), mesh network, etc. In this case, the UE 116 may perform scheduling operations, resource selection operations, and / or other operations performed by the base station as described elsewhere herein. For example, the base station may configure the UE 116 via downlink control information (DCI), radio resource control (RRC) signaling, medium access control-control element (MAC-CE) or via system information (e.g., system information block (SIB)).

[0102] FIG. 3B illustrates an example gNB 102 according to some embodiments of the 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 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.

[0103] 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.

[0104] 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.

[0105] 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.

[0106] 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 implementations, the controller / processor 378 includes at least one microprocessor or microcontroller.

[0107] 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 disclosure. In some implementations, 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.

[0108] 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.

[0109] 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.

[0110] 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.

[0111] 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).

[0112] Those skilled in the art will understand that, "terminal" and "terminal device" as used herein include not only devices with wireless signal receiver which have no transmitting capability, but also devices with receiving and transmitting hardware which can carry out bidirectional communication on a bidirectional communication link. Such devices may include cellular or other communication devices with single-line displays or multi-line displays or cellular or other communication devices without multi-line displays; a PCS (personal communications service), which may combine voice, data processing, fax and / or data communication capabilities; a PDA (Personal Digital Assistant), which may include a radio frequency receiver, a pager, an internet / intranet access, a web browser, a notepad, a calendar and / or a GPS (Global Positioning System) receiver; a conventional laptop and / or palmtop computer or other devices having and / or including a radio frequency receiver. "Terminal" and "terminal device" as used herein may be portable, transportable, installed in vehicles (aviation, sea transportation and / or land), or suitable and / or configured to operate locally, and / or in distributed form, operate on the earth and / or any other position in space. "Terminal" and "terminal device" as used herein may also be a communication terminal, an internet terminal, a music / video playing terminal, such as a PDA, a MID (Mobile Internet Device) and / or a mobile phone with music / video playing functions, a smart TV, a set-top box and other devices.

[0113] With the rapid development of information industry, especially the increasing demand from mobile Internet and internet of things (IoT), it brings unprecedented challenges to the future mobile communication technology. In order to meet the unprecedented challenges, the communication industry and academia have carried out extensive research on the fifth generation (5G) mobile communication technology to face the 2020s. At present in ITU report ITU-R M.[IMT.VISION], the framework and overall goals of the future 5G has been discussed, in which the demand outlook, application scenarios and important performance indicators of 5G are described in detail. With respect to new requirements in 5G, ITU report ITU-R M.[IMT.FUTURE TECHNOLOGY TRENDS] provides information related to the technology trends of 5G, aiming at solving significant problems such as significantly improved system throughput, consistent user experience, scalability to support IoT, delay, energy efficiency, cost, network flexibility, support of emerging services and flexible spectrum utilization. In 3GPP (3rd Generation Partnership Project), the first stage of 5G is already in progress. To support more flexible scheduling, the 3GPP decides to support variable hybrid automatic repeat request-acknowledgement (HARQ-ACK) feedback delay in 5G. In existing Long Term Evolution (LTE) systems, a time from reception of downlink data to uplink transmission of HARQ-ACK is fixed. For example, in Frequency Division Duplex (FDD) systems, the delay is 4 subframes. In Time Division Duplex (TDD) systems, a HARQ-ACK feedback delay is determined for a corresponding downlink subframe based on an uplink and downlink configuration. In 5G systems, whether FDD or TDD systems, for a determined downlink time unit (for example, a downlink slot or a downlink mini slot; for another example, a PDSCH time unit), the uplink time unit (for example, a PUCCH time unit) that can feedback HARQ-ACK is variable. For example, the delay of HARQ-ACK feedback can be dynamically indicated by physical layer signaling, or different HARQ-ACK delays can be determined based on factors such as different services or user capabilities.

[0114] The 3GPP has defined three directions of 5G application scenarios-eMBB (enhanced mobile broadband), mMTC (massive machine-type communication) and URLLC (ultra-reliable and low-latency communication). The eMBB scenario aims to further improve data transmission rate on the basis of the existing mobile broadband service scenario, so as to enhance user experience and pursue ultimate communication experience between people. mMTC and URLLC are, for example, the application scenarios of the Internet of Things, but their respective emphases are different: mMTC being mainly information interaction between people and things, while URLLC mainly reflecting communication requirements between things.

[0115] In a communication system, a UE may receive a reference signal (RS), and perform channel measurement based on the RS, and estimate a channel state based on the channel measurement to obtain channel state information (CSI). The UE may determine (e.g., calculate or derive) a CSI parameter and send a CSI report that includes the CSI parameter. For example, the RS may include a CSI-RS, a synchronization signal block (SSB), a demodulation reference signal (DM-RS), a phase tracking reference signal (PT-RS), and / or the like. The CSI may include one or more of a channel quality indicator (CQI), a precoding matrix indicator (PMI), a CSI-RS resource indicator (CRI), a synchronization signal (SS) / physical broadcast channel (PBCH) block resource indicator (SSBRI), a layer indicator (LI), a rank indicator (RI), a reference signal receive power (RSRP), or a signal-to-interference-and-noise ratio (SINR).

[0116] In some cases, the channel state of the network may change dynamically, and thus how to report the channel state of the network quickly is a problem that needs to be solved. There is therefore a need for an enhanced uplink signaling method to report CSI.

[0117] Example embodiments of the disclosure provide a method performed by a terminal, a terminal, a method performed by a base station, a base station and a non-transitory computer-readable storage medium in a wireless communication system. Hereinafter, various example embodiments of the disclosure will be described in detail with reference to the accompanying drawings.

[0118] In the example embodiments of the disclosure, for the convenience of description, a first transceiving node and a second transceiving node are defined. For example, the first transceiving node may be a base station, and the second transceiving node may be a UE. For another example, the example embodiments of the disclosure may be applicable to the scenario of sidelink communication, in which case, the first transceiving node may be a UE, and the second transceiving node may be another UE. Therefore, the first transceiving node and the second transceiving node may each be any suitable communication node. In the following description, the base station is taken as an example (but not limited thereto) to illustrate the first transceiving node, and the UE is taken as an example (but not limited thereto) to illustrate the second transceiving node.

[0119] In describing a wireless communication system and in the disclosure described below, transferring methods (or configuration methods) of higher layer signaling or higher layer signals may be signal transferring methods for transferring information from a base station to a terminal over a downlink (DL) data channel of a physical layer or from a terminal to a base station over an uplink (UL) data channel of a physical layer, and examples of the signal transferring methods may include signal transferring methods for transferring information via Radio Resource Control (RRC) signaling, Packet Data Convergence Protocol (PDCP) signaling, or a Medium Access Control (MAC) Control Element (CE).

[0120] In the following description of the example embodiments of the disclosure, higher layer signaling may be signaling corresponding to at least one or a combination of one or more of the following signaling.

[0123] - RRC signaling

[0124] - MAC CE

[0125] Physical layer (Layer 1 (L1)) signaling may be signaling corresponding to at least one or a combination of one or more of the following signaling.

[0133] - PUCCH (physical uplink control channel)

[0134] - UCI (uplink control information)

[0135] - Paging

[0136] - PRACH (physical random access channel)

[0137] - RAR (random access response)

[0138] In the example embodiments of the disclosure, uplink control signaling may include physical layer signaling and / or higher layer signaling. As described above, the physical layer signaling may include UCI and / or PUCCH and / or PRACH, and the higher layer signaling may include RRC signaling and / or a MAC CE.

[0139] In the example embodiments of the disclosure, downlink control signaling may include physical layer signaling and / or higher layer signaling. As mentioned above, the physical layer signaling may include one or more of PDCCH, DCI, UE-specific DCI, group common DCI, common DCI, scheduling DCI (for example, DCI for scheduling downlink or uplink data), non-scheduling DCI, paging, and RAR, and the higher layer signaling may include one or more of a MIB, a SIB or SIB X (X = 1, 2, ...), RRC signaling or a MAC CE. Therefore, "configuring or indicating X through downlink control signaling" will be understood as configuring or indicating X through physical layer signaling, or configuring or indicating X through higher layer signaling, or configuring or indicating X through a combination of higher layer signaling and physical layer signaling.

The common DCI may be DCI common to a part of UEs, such as group common DCI, and the common DCI may also be DCI common to all of UEs in a serving cell (e.g., cell common DCI). The DCI may also be multicast DCI or broadcast DCI. The DCI may be uplink DCI (e.g., DCI for scheduling a PUSCH) and / or downlink DCI (e.g., DCI for scheduling a PDSCH).

[0155] It should be noted that in the description of the example embodiments of the disclosure, the following terms may be used interchangeably:

[0161] In implementations described In combination with FIG. 4 or 5, the second control signaling may be control signaling transmitted by the second transceiving node to the first transceiving node. In the following examples, uplink control signaling is taken as an example (but is not limited thereto) to illustrate the second control signaling. The uplink control signaling may be UCI (Uplink Control Information) carried by a PUCCH (Physical Uplink Control Channel) and / or control signaling (e.g., higher signaling) carried by a PUSCH (Physical Uplink Shared Channel). A type of UCI may include one or more of: HARQ-ACK information, SR (Scheduling Request), LRR (Link Recovery Request), CSI (Chanel State Information), CG (Configured Grant) UCI，or UTO (unused transmission occasion)-UCI. In the example embodiments of the disclosure, when UCI is carried by a PUCCH, the UCI may be used interchangeably with the PUCCH.

[0162] In some implementations, a PUCCH with an SR may be a PUCCH with a positive SR and / or a negative SR. The SR may be the positive SR and / or the negative SR.

[0163] In some implementations, the CSI report may be Part 1 CSI and / or Part 2 CSI.

[0164] In implementations described In combination with FIG. 4 or 5, a time unit where the first transceiving node transmits the first data and / or the first control signaling may be a downlink time unit, such as a downlink slot.

[0165] In implementations described In combination with FIG. 4 or 5, a time unit where the second transceiving node transmits the second data and / or the second control signaling may be an uplink time unit, such as an uplink slot or PUCCH slot or PCell (primary cell) slot or PUCCH slot on PCell. The "PUCCH slot" may be understood as a PUCCH transmission slot.

[0166] In the example embodiments of the disclosure, a time unit (for example, a downlink time unit or a uplink time unit) may be one or more slots, one or more subslots, one or more OFDM symbols, one or more spans, one or more subframes, one or more frames or one or more half frames.

[0167] FIG. 6 illustrates a flowchart of a method 600 performed by a base station according to some example embodiments of the disclosure.

[0169] In operation S620, the base station receives uplink data and / or uplink control signaling from the UE. For example, the base station receives the uplink data and / or the uplink control signaling from the UE in a time unit.

[0170] In some implementations, operations S610 and / or S620 may be performed based on the methods described according to various example embodiments of the disclosure (e.g., various methods / manners described below).

[0171] In some implementations, the method 600 may omit one or more of operation S610 or S620, or may include additional operations, for example, the operations performed by the base station based on the methods described according to various example embodiments of the disclosure (e.g., various methods / manners described below).

[0172] FIG. 7 illustrates a flowchart of a method 700 performed by a UE according to example embodiments of the disclosure.

[0173] Referring to FIG. 7, in operation S710, the UE may receive downlink (DL) data (e.g., downlink data carried by PDSCH(s)) and / or downlink control signaling from a base station. For example, the UE may receive the downlink data and / or the downlink control signaling from the base station based on predefined rules and / or received configuration parameters.

[0175] In operation S730, the UE transmits the uplink data and / or the uplink control signaling to the base station. For example, the UE transmits the uplink data and / or the uplink control signaling to the base station in the determined time unit. For another example, the UE transmits the uplink data and / or the uplink control signaling to the base station in the determined time unit according to the determined transmission power.

[0176] [HARQ / scheduling general timing]

[0177] In some implementations, operations S710 and / or S720 and / or S730 may be performed based on the methods described according to various example embodiments of the disclosure (e.g., various methods / manners described below).

[0178] In some implementations, the method 700 may omit one or more of operation S710, S720 or S730, or may include additional operations, for example, the operations performed by the UE (terminal) based on the methods described according to various example embodiments of the disclosure (e.g., various methods / manners described below).

[0179] In some implementations, acknowledgement / negative acknowledgement (ACK / NACK) for downlink transmission(s) may be performed through HARQ-ACK.

[0180] Some examples of uplink transmission timing according to some example embodiments of the disclosure will be described below with reference to FIGS. 8A-8C.

[0181] In an example, the UE receives a DCI format and receives a PDSCH according to time domain resources indicated by the DCI format. For example, a parameter K0 may be used to indicate a time unit interval (offset) between the PDSCH scheduled by the DCI format and the DCI format (e.g., a PDCCH carrying the DCI format), where K0 may be in units of slots, for example, PDSCH slots (that is, slots of an active BWP in a serving cell where PDSCH is located). For example, FIG. 8A gives an example in which K0=1. In the example illustrated in FIG. 8A, the time unit interval from the PDSCH scheduled by the DCI format to the PDCCH carrying the DCI format is one slot. In the example embodiments of the disclosure, "the UE receives a DCI / DCI format" may refer to that "the UE detects the DCI / DCI format."

[0182] In another example, the UE receives a DCI format and transmits a PUSCH based on time domain resources indicated by the DCI format. For example, a timing parameter K2 may be used to indicate a time unit interval between the PUSCH scheduled by the DCI format and the DCI format (e.g., a PDCCH carrying the DCI format), where K2 may be in units of slots, for example, PUSCH slots (that is, slots of an active BWP in a serving cell where PUSCH is located). For example, FIG. 8B gives an example in which K2 = 1. In the example illustrated in FIG. 8B, the time unit interval between the PUSCH scheduled by the DCI format and the PDCCH carrying the DCI is one slot. K2 may also be used to indicate a time unit interval between a PDCCH for activating CG (configured grant) PUSCH(s) and the first activated CG PUSCH (e.g., CG PUSCH transmission occasion). In examples of the disclosure, unless otherwise specified, the PUSCH may be a dynamically scheduled PUSCH (e.g., scheduled by DCI) (e.g., which may be referred to as DG (dynamic grant) PUSCH, in the example embodiments of the disclosure) and / or a PUSCH not scheduled by DCI (e.g., CG PUSCH).

[0183] In yet another example, the UE receives a PDSCH, and may transmit HARQ-ACK information for the PDSCH reception in a PUCCH in a time unit (e.g., uplink time unit). For example, a timing parameter (which may also be referred to as a timing value) K1 (e.g., the higher layer parameter dl-DataToUL-ACK) may be used to indicate a time unit interval between the PUCCH with the HARQ-ACK information for the PDSCH reception and the PDSCH, and K1 may be in units of time units (e.g., uplink time units, such as PUCCH time units), such as slots or subslots. For example, FIG. 8A gives an example in which K1 = 3. In the example illustrated in FIG. 8A, the time unit interval between the PUCCH with the HARQ-ACK information for the PDSCH reception and the PDSCH is 3 slots. It should be noted that in the example embodiments of the disclosure, the timing parameter K1 may be used interchangeably with a time unit offset K1, the timing parameter K0 may be used interchangeably with a time unit offset K0, and the timing parameter K2 may be used interchangeably with a time unit offset K2.

[0184] The PDSCH may be a PDSCH scheduled by DCI and / or a SPS (semi-persistent scheduling) PDSCH. The UE periodically receives the SPS PDSCH after the SPS PDSCH is activated by the DCI. In examples of the disclosure, the SPS PDSCH may be equivalent to a PDSCH not scheduled by the DCI / PDCCH. After the SPS PDSCH is released (deactivated), the UE will no longer receive the SPS PDSCH.

[0185] In the example embodiments of the disclosure, HARQ-ACK may be HARQ-ACK for a SPS PDSCH reception (e.g., HARQ-ACK not indicated by DCI) and / or HARQ-ACK indicated by a DCI format (e.g., HARQ-ACK for a PDSCH reception scheduled by a DCI format, where the PDSCH reception may be a PDSCH reception providing a transport block (TB) with enabled HARQ-ACK information). Or, for example, HARQ-ACK may be HARQ-ACK for a DCI format without scheduling PDSCH.

[0186] In yet another example, the UE receives DCI (e.g., DCI indicating SPS PDSCH release (deactivation)), and may transmit HARQ-ACK information for the DCI in a PUCCH in a time unit (e.g., uplink time unit). For example, the timing parameter K1 may be used to indicate a time unit interval between the PUCCH with the HARQ-ACK information for the DCI and the DCI, and K1 may be in units of time units (e.g., uplink time units), such as slots or subslots. For example, FIG. 8C gives an example in which K1 = 3. In the example of FIG. 8C, the time unit interval between the PUCCH with the HARQ-ACK information for the DCI and the DCI is 3 slots. For example, the timing parameter K1 may be used to indicate a time unit interval between a PDCCH reception carrying DCI indicating SPS PDSCH release (deactivation) and the PUCCH feeding back HARQ-ACK for the PDCCH reception.

[0187] In some implementations, the UE may report (or signal / transmit) a UE capability to the base station or indicate the UE capability in operation S720. For example, the UE reports (or signals / transmits) the UE capability to the base station by transmitting a PUSCH. In this case, the PUSCH transmitted by the UE includes the UE capability information. A UE capability may be a UE capability parameter or a value of a UE capability parameter.

[0188] In some implementations, the base station may configure higher layer signaling for the UE based on a UE capability received from the UE.

[0189] In some implementations, downlink channels (downlink resources) may include PDCCHs and / or PDSCHs. Uplink channels (uplink resources) may include PUCCHs and / or PUSCHs.

[0190] [Two levels of priority]

[0191] In some implementations, the UE may be configured with two levels of priorities for uplink transmission (for example, the UE is configured with the higher layer parameterPUCCH-ConfigurationList). The PUCCH resource configured by the first PUCCH-Config is a PUCCH resource of a lower priority, and the PUCCH resource configured by the second PUCCH-Config is a PUCCH resource of a higher priority. For another example, the priority of a PUCCH or a PUSCH may be indicated in a DCI format, for example, by a physical layer priority index (phy-PriorityIndex) field.

[0192] When two or more uplink physical channels on a serving cell overlap (for example, overlap in time), or PUCCH(s) and PUSCH(s) overlap (for example, overlap in time), it is necessary to resolve the overlapping for the physical channels. "Resolving the overlapping for the physical channels" may refer to "resolving the collision of overlapping physical channels". The resulting physical channels after resolving the overlapping for the physical channels do not overlap or collide. The overlapping of physical channels may be resolved by multiplexing and / or prioritization. The multiplexing may refer to multiplexing UCI of two or more physical channels in a physical channel. For example, the multiplexing of multiple PUCCHs and / or PUSCHs that overlap in time domain may include multiplexing UCI of the PUCCHs in a PUCCH or PUSCH. It should be noted that in the description of the example embodiments of the disclosure, "resolving the overlapping for the physical channels" may also be used interchangeably with "determining the overlapping of the physical channels". The prioritization may refer to transmitting a physical channel of the higher priority and not transmitting a physical channel of the lower priority. It should be noted that in the description of the example embodiments of the disclosure, "Not transmitting a physical channel", "cancelling the transmission of a physical channel", "stopping the transmission of a physical channel", and "deprioritizing the priority of a physical channel" may be used interchangeably. For example, the prioritization of two PUCCHs and / or PUSCHs overlapping in time domain by the UE may include that the UE transmits the PUCCH or the PUSCH of the higher priority and / or the UE does not transmit the PUCCH or the PUSCH of the lower priority. In the embodiments of the disclosure, unless otherwise specified, "resolving the overlapping of physical channels" may be understood as resolving the overlapping of physical channels with the same physical layer priority.

[0193] For example, if the UE is configured / indicated to multiplex UCIs (e.g., HARQ-ACK) of different priorities via higher layer signaling (e.g., via higher layer parameteruci-MuxWithDiffPrio), when resolving the overlapping for physical channels with different priorities, the UE may multiplex UCIs (e.g., HARQ-ACK) with different priorities; otherwise (e.g., if the UE is not configured the parameter for multiplexing UCIs with different priorities), when resolving the overlapping for physical channels with different priorities, the UE performs prioritization for PUCCHs and / or PUSCHs with different priorities.

[0194] For example, the two levels of priorities may include a first priority and a second priority which are different from each other. In an example, the first priority may be higher than the second priority, that is, the first priority is the higher priority, and the second priority is the lower priority. In another example, the first priority may be lower than the second priority. However, embodiments of the disclosure are not limited to this, and for example, the UE may be configured with more than two levels of priorities. For the sake of convenience, in some example embodiments of the disclosure, description will be made considering that the first priority is higher than the second priority. It should be noted that all embodiments of the disclosure are applicable to situations where the first priority may be higher than the second priority; all embodiments of the disclosure are applicable to situations where the first priority may be lower than the second priority; and all embodiments of the disclosure are applicable to situations where the first priority may be equal to the second priority. In some example embodiments of the disclosure, the terms "first priority", "higher priority", "greater priority index" and "priority index 1" may be used interchangeably. In the example embodiments of the disclosure, the terms "second priority", "lower priority", "smaller priority index" and "priority index 0" may be used interchangeably.

[0195] [Subslot]

[0196] In some implementations, the UE may be configured with a subslot-based PUCCH transmission. For example, a subslot length parameter (which may also be referred to as a parameter with respect to a subslot length in the example embodiments of the disclosure) (e.g., the higher layer parameter subslotLengthForPUCCH) of each PUCCH configuration parameter of the first PUCCH configuration parameter and the second PUCCH configuration parameter may be 7 OFDM symbols or 6 OFDM symbols or 2 OFDM symbols. Subslot configuration length parameters in different PUCCH configuration parameters may be configured separately. If no subslot length parameter is configured in a PUCCH configuration parameter, the scheduling time unit of the PUCCH configuration parameter is one slot by default. If a subslot length parameter is configured in the PUCCH configuration parameter, the scheduling time unit of the PUCCH configuration parameter is L (L is the configured subslot configuration length) OFDM symbols.

[0197] The mechanism of a slot-based PUCCH transmission is basically the same as that of a subslot-based PUCCH transmission. In the disclosure, a slot may be used to represent a PUCCH occasion unit; for example, if the UE is configured with subslots, a slot which is a PUCCH occasion unit may be replaced with a subslot. For example, it may be specified by protocols that if the UE is configured with the subslot length parameter (e.g., the higher layer parameter subslotLengthForPUCCH), unless otherwise indicated, a number of symbols included in the slot of the PUCCH transmission is indicated by the subslot length parameter.

[0198] For example, if the UE is configured with the subslot length parameter, and a subslot n is the last uplink subslot overlapping with a PDSCH reception or PDCCH reception (e.g., SPS PDSCH release, and / or indicating SCell dormancy, and / or triggering a Type-3 HARQ-ACK codebook report and without scheduling PDSCH reception), then HARQ-ACK information for the PDSCH reception or PDCCH reception is transmitted in an uplink subslot n+k, where k is determined by the timing parameter K1 (the definition of the timing parameter K1 may refer to the previous description). For another example, if the UE is not configured with the subslot length parameter, and a slot n is the last uplink slot overlapping with a downlink slot where the PDSCH reception or PDCCH reception is located, then the HARQ-ACK information for the PDSCH reception or PDCCH reception is transmitted in an uplink slot n+k, where K is determined by the timing parameter K1.

[0199] [Multicast service (MBS)]

[0200] In the example embodiments of the disclosure, unicast may refer to a manner in which a network communicates with a UE, and multicast (or groupcast) may refer to a manner in which a network communicates with multiple UEs. For example, a unicast PDSCH may be a PDSCH received by one UE, and scrambling of the PDSCH may be based on a Radio Network Temporary Identifier (RNTI) specific to the UE, e.g., Cell-RNTI (C-RNTI). A multicast PDSCH may be a PDSCH received by more than one UE simultaneously, and scrambling of the multicast PDSCH may be based on a UE-group common RNTI. For example, the UE-group common RNTI for scrambling the multicast PDSCH may include an RNTI (which may be referred to as Group RNTI (G-RNTI) in the example embodiments of the disclosure) for scrambling of a dynamically scheduled multicast transmission (e.g., PDSCH) or an RNTI (which may be referred to as group configured scheduling RNTI (G-CS-RNTI) in the example embodiments of the disclosure) for scrambling of a multicast SPS transmission (e.g., SPS PDSCH). UCI of the unicast PDSCH may include HARQ-ACK information, an SR, or CSI of the unicast PDSCH reception. UCI of the multicast PDSCH may include HARQ-ACK information of the multicast PDSCH reception. In the example embodiments of the disclosure, "multicast" may also be replaced by "broadcast".

[0201] [HARQ-ACK codebook]

[0202] In operation S710, the UE may receive downlink data (e.g., downlink data carried by PDSCH(s)) and / or downlink control signaling (e.g., DCI format(s) carried by PDCCH(s)) from the base station.

[0203] In operation S720, the UE may determine HARQ-ACK information bits transmitted in an uplink slot based on the downlink data and / or the downlink control signaling. For example, determining the HARQ-ACK information bits transmitted in the uplink slot includes at least one of the following:

[0204] - determining values of the HARQ-ACK information bits;

[0205] - determining the order of the HARQ-ACK information bits;

[0206] -determining a total number of the HARQ-ACK information bits.

[0207] In operation S730, the UE transmits the HARQ-ACK information bits to the base station. Here, the UE may transmit the HARQ-ACK information bits in a PUCCH or PUSCH.

[0208] In some implementations, a HARQ-ACK codebook may include HARQ-ACK information (in the disclosure, which may also be called HARQ-ACK information bits) for one or more PDSCH receptions and / or DCI format(s) (e.g., DCI format without scheduling PDSCH reception). HARQ-ACK information for a PDSCH reception may be understood as HARQ-ACK information for transport block(s) (TB(s)) included in the PDSCH reception. In case that the UE is configured with PDSCH CBG (code block group) transmission (for example, the parameterPDSCH-CodeBlockGroupTransmissionis configured), or in case that one PDSCH reception includes one or more CBGs, HARQ-ACK information for a PDSCH reception may be understood as HARQ-ACK information for the CBGs included in the PDSCH reception. If HARQ-ACK information for one or more PDSCH receptions and / or DCI(s) is multiplexed in a time unit (e.g., uplink time unit) for transmission (e.g., transmission in a PUCCH in a same time unit), the UE may generate the HARQ-ACK codebook based on a predefined rule. The UE generating the HARQ-ACK codebook may include ordering the HARQ-ACK information bits and / or compressing (e.g., bundling) the HARQ-ACK information bits. For example, if a TB or CBG in a PDSCH reception is successfully decoded, HARQ-ACK information for the TB or CBG in the PDSCH reception is positive ACK. The positive ACK may be represented by 1 in the HARQ-ACK codebook, for example. If a TB or CBG in a PDSCH reception is not successfully decoded, HARQ-ACK information for the TB or CBG in the PDSCH reception is negative ACK (NACK). The NACK may be represented by 0 in the HARQ-ACK codebook, for example. For example, the UE may generate the HARQ-ACK codebook based on pseudo codes specified by protocols. In an example, if the UE receives a DCI format that indicates SPS PDSCH release (deactivation), the UE transmits HARQ-ACK information (ACK) for the DCI format. In another example, if the UE receives a DCI format that indicates secondary cell dormancy, the UE transmits HARQ-ACK information (ACK) for the DCI format. In yet another example, if the UE receives a DCI format that indicates to transmit HARQ-ACK information (e.g., a Type-3 HARQ-ACK codebook) of all HARQ-ACK processes of all configured serving cells, the UE transmits the HARQ-ACK information of all of the HARQ-ACK processes of all of the configured serving cells. In order to reduce a size of the Type-3 HARQ-ACK codebook, in an enhanced Type-3 HARQ-ACK codebook, the UE may transmit HARQ-ACK information of a specific HARQ-ACK process of a specific serving cell based on an indication of the DCI. In yet another example, if the UE receives a DCI format that schedules a PDSCH reception, the UE transmits HARQ-ACK information for the PDSCH reception. In yet another example, the UE receives a SPS PDSCH, and the UE transmits HARQ-ACK information for the SPS PDSCH reception. In yet another example, if the UE is configured by higher layer signaling to receive a SPS PDSCH, the UE transmits HARQ-ACK information for the SPS PDSCH reception. The reception of the SPS PDSCH configured by higher layer signaling may be cancelled by other signaling. In yet another example, if at least one uplink symbol (e.g., OFDM symbol) of the UE in a semi-static frame structure configured by higher layer signaling overlaps with a symbol of the SPS PDSCH reception, the UE does not receive the SPS PDSCH. In yet another example, if the UE is configured by higher layer signaling to receive a SPS PDSCH according to a predefined rule, the UE transmits HARQ-ACK information for the SPS PDSCH reception. It should be noted that, in the example embodiments of the disclosure, "'A' overlaps with 'B'" may mean that 'A' at least partially overlaps with 'B'. That is, "'A' overlaps with 'B'" includes a case where 'A' completely overlaps with 'B'. "'A' overlaps with 'B'" may mean that 'A' overlaps with 'B' in time domain and / or 'A' overlaps with 'B' in frequency domain.

[0209] In some implementations, if HARQ-ACK information transmitted (or multiplexed) in a same time unit (e.g., uplink time unit) does not include HARQ-ACK information for any DCI format, nor does it include HARQ-ACK information for a dynamically scheduled PDSCH reception (e.g., a PDSCH reception scheduled by a DCI format) and / or DCI, or the HARQ-ACK information transmitted (or multiplexed) in the same time unit (e.g., uplink time unit) only includes HARQ-ACK information for one or more SPS PDSCH receptions, the UE may generate HARQ-ACK information (e.g., HARQ-ACK information only for SPS PDSCH receptions) according to a rule for generating a HARQ-ACK codebook for SPS PDSCH receptions. The UE may multiplex the HARQ-ACK information only for SPS PDSCH receptions in a specific PUCCH resource. For example, if the UE is configured with a PUCCH list parameter for SPS (e.g.,SPS-PUCCH-AN-List), the UE multiplexes the HARQ-ACK information only for SPS PDSCH receptions in a PUCCH of a PUCCH list for SPS. For example, the UE determines a PUCCH resource in the PUCCH list for the SPS according to a number of HARQ-ACK information bits. If the UE is not configured with the PUCCH list parameter for SPS, the UE multiplexes the HARQ-ACK information only for SPS PDSCH receptions in a PUCCH resource specific to SPS HARQ-ACK (for example, the PUCCH resource is configured by the parametern1PUCCH-AN).

[0210] In some implementations, if HARQ-ACK information transmitted (or multiplexed) in a same time unit (e.g., uplink time unit) includes HARQ-ACK information for a DCI format, and / or a dynamically scheduled PDSCH reception (e.g., a PDSCH reception scheduled by a DCI format), the UE may generate HARQ-ACK information according to a rule for generating a HARQ-ACK codebook for a dynamically scheduled PDSCH reception and / or a DCI format. For example, the UE may determine to generate a semi-static HARQ-ACK codebook (e.g., Type-1 HARQ-ACK codebook) or a dynamic HARQ-ACK codebook (e.g., Type-2 HARQ-ACK codebook) according to a HARQ-ACK codebook configuration parameter for a PDSCH reception (e.g., the higher layer parameter pdsch-HARQ-ACK-Codebook). For example, if the UE is configured with the HARQ-ACK codebook configuration parameter (e.g., higher layer parameter pdsch-HARQ-ACK-Codebook) as semi-static, the UE may generate a semi-static HARQ-ACK codebook. If the UE is configured with the HARQ-ACK codebook configuration parameter (e.g., higher layer parameter pdsch-HARQ-ACK-Codebook) as dynamic, the UE may generate a dynamic HARQ-ACK codebook. The dynamic HARQ-ACK codebook may also be an enhanced dynamic HARQ-ACK codebook (e.g., Type-2 HARQ-ACK codebook based on grouping and HARQ-ACK retransmission). The UE may multiplex the HARQ-ACK information in a PUCCH resource for HARQ-ACK associated with dynamically scheduling, which may be configured in a resource set list parameter (e.g., parameter resourceSetToAddModList). The UE determines a PUCCH resource set (e.g., parameter PUCCH-ResourceSet) in a resource set list according to a number of HARQ-ACK information bits, and the PUCCH resource may be determined as a PUCCH in the PUCCH resource set according to a PRI (PUCCH Resource Indicator) field indication in the last DCI format.

[0211] In some implementations, if HARQ-ACK information transmitted (multiplexed) in a same time unit (e.g., uplink time unit) includes only HARQ-ACK information for SPS PDSCH receptions (e.g., PDSCH receptions not scheduled by DCI formats), the UE may generate the HARQ-ACK codebook according to a rule for generating a HARQ-ACK codebook for SPS PDSCH receptions (e.g., the pseudo code for a HARQ-ACK codebook for SPS PDSCH receptions).

[0212] [Type-1 HARQ-ACK codebook]

[0213] The semi-static HARQ-ACK codebook (e.g., Type-1 HARQ-ACK codebook), may determine the size of the HARQ-ACK codebook and an order of HARQ-ACK information bits according to a semi-statically configured parameter (e.g., a parameter configured by higher layer signaling).

[0214] For a serving cell c, an active downlink BWP (bandwidth part), and an active uplink BWP, the UE determines a set of MA,coccasions for candidate PDSCH receptions for which the UE can transmit corresponding HARQ-ACK information in a PUCCH in an uplink slot nU.

[0215] MA,cmay be determined by at least one of the following:

[0216] a) a set of HARQ-ACK slot timing values K1 associated with the active uplink BWP on a primary cell or PUCCH-sScell (PUCCH switching SCell);

[0217] b) a set of row indexes of a time domain resource allocation (TDRA) table associated with the active downlink BWP;

[0218] c) , where is the configuration of a downlink subcarrier spacing (SCS) of the downlink active BWP, and is the configuration of an uplink subcarrier spacing of the active uplink BWP.

[0219] d) a semi-static uplink and downlink frame structure configuration, such as the parametertdd-UL-DL-ConfigurationCommonand the parametertdd-UL-DL-ConfigurationDedicated.

[0220] e) a downlink slot offset parameter (e.g., the higher layer parameter ) for the serving cellcand its corresponding slot offset SCS (e.g., the higher layer parameter ), and a slot offset parameter (e.g., the higher layer parameter ) for a primary cell and its corresponding slot offset SCS (e.g., the higher layer parameter ).

[0221] In the description of the example embodiments of the disclosure, the set of the parameter K1 is used to determine a candidate uplink slot, and then determine candidate downlink slots according to the candidate uplink slot. The candidate downlink slots satisfy at least one of the following conditions: (i) if the time unit of the PUCCH is a subslot, the end of at least one candidate PDSCH reception in the candidate downlink slots overlaps with the candidate uplink slot in time domain; or (ii) if the time unit of the PUCCH is a slot, the end of the candidate downlink slots overlaps with the candidate uplink slot in time domain. It should be noted that, in the description of the example embodiments of the disclosure, a starting symbol may be used interchangeably with a starting position, and an end symbol may be used interchangeably with an end position. In some implementations, the starting symbol may be replaced by the end symbol, and / or the end symbol may be replaced by the starting symbol.

[0222] A number of PDSCH receptions in a candidate downlink slot for which HARQ-ACK needs to be fed back is determined by a maximum value of a number of non-overlapping valid candidate PDSCH receptions in the downlink slot (e.g., the valid candidate PDSCH receptions may be candidate PDSCH receptions that do not overlap with semi-statically configured uplink symbols). Time domain resources occupied by the candidate PDSCH receptions may be determined by (i) a time domain resource allocation table configured by higher layer signaling (in the example embodiments of the disclosure, it may also be referred to as a table associated with time domain resource allocation) and (ii) a certain row in time domain resource allocation table dynamically indicated by a DCI. Each row in time domain resource allocation table may define information with respect to time domain resource allocation. For example, for the time domain resource allocation table, an indexed row defines a timing value (e.g., time unit (e.g., slot) offset (e.g., K0)) between a PDCCH and a PDSCH, and a start and length indicator (SLIV), or directly defines a starting symbol and allocation length. For example, for the first row of the time domain resource allocation table, a starting OFDM symbol is 0 and an OFDM symbol length is 4; for the second row of the time domain resource allocation table, the starting OFDM symbol is 4 and the OFDM symbol length is 4; and for the third row of the time domain resource allocation table, the starting OFDM symbol is 7 and the OFDM symbol length is 4. The DCI for scheduling the PDSCH may indicate any row in time domain resource allocation table. When all OFDM symbols in the downlink slot are downlink symbols, the maximum value of the number of non-overlapping valid PDSCHs in the downlink slot is 2. At this time, the Type-1 HARQ-ACK codebook may need to feed back HARQ-ACK information for two PDSCHs in the downlink slot on the serving cell.

[0223] FIGS. 9A and 9B illustrate examples of time domain resource allocation tables (TDRAs). Specifically, FIG. 9A illustrates a time domain resource allocation table in which one PDSCH is scheduled in one row, and FIG. 9B illustrates a time domain resource allocation table in which multiple PDSCHs are scheduled in one row. Referring to FIG. 9A, each row corresponds to a set of {K0, mapping type, SLIV}, which includes a timing parameter K0 value, a mapping type, and an SLIV. Referring to FIG. 9B, unlike FIG. 9A, each row corresponds to multiple sets of {K0, mapping type, SLIV}.

[0224] [Type-2 HARQ-ACK codebook]

[0225] In some implementations, the dynamic HARQ-ACK codebook (e.g., Type-2 HARQ-ACK codebook) and / or the enhanced dynamic HARQ-ACK codebook (e.g., Type-2 HARQ-ACK based on grouping and HARQ-ACK retransmission) may determine a size and an order of the HARQ-ACK codebook according to an assignment indicator. For example, the assignment indicator may be a DAI (Downlink Assignment Indicator). In the following embodiments, the assignment indicator as the DAI is taken as an example for illustration. However, the example embodiments of the disclosure are not limited thereto, and any other suitable assignment indicator may be adopted. It should be noted that the method for dynamic HARQ-ACK codebook in the disclosure may also be used for enhanced dynamic HARQ-ACK codebook.

[0226] In some implementations, the DAI may include at least one of a first DAI and a second DAI.

[0227] In some examples, the first DAI may be a C-DAI (Counter-DAI), and the first DAI may be a cumulative number of the downlink assignment index. The value of the first DAI field in a DCI format is a cumulative number of {serving cell, PDCCH monitoring occasion (MO)}-pair(s) up to the current serving cell and the current time unit, where the time unit may be a time unit of the PDCCH reception, for example, PDCCH monitoring occasion. The {serving cell, PDCCH MO}-pairs may include DCI formats scheduling PDSCH receptions and / or DCI formats having associated / corresponding HARQ-ACK information bits without scheduling PDSCH receptions. The first DAI may be included in a downlink DCI format. HARQ-ACK information for a PDSCH reception scheduled by a DCI format and / or a DCI format without scheduling PDSCH reception is transmitted in a same time unit (for example, transmitted in a same PUCCH in a same time unit). The second DAI may be T-DAI (Total-DAI). The second DAI may be a total number of the downlink assignment index. The value of the second DAI field in a DCI format may be a total number of {serving cell, PDCCH MO}-pair(s) up to the current time unit. The second DAI may be included in a downlink DCI format and / or an uplink DCI format. The second DAI included in an uplink DCI format may be also called UL DAI.

[0228] In some implementations, the first DAI may be sorted in the following order:

[0229] - first in ascending order of serving cell index (e.g. scheduled serving cell index), and

[0230] - second in ascending order of PDCCH MO index.

[0231] In some implementations, the first DAI may also be sorted in the following order. For example, if the UE reports a capability to support more than one PDSCH reception on a serving cell scheduled from a PDCCH MO (for example, PDSCH receptions scheduled by more than one PDCCH), the first DAI may be sorted in the following order:

[0232] - first in increasing order of the PDSCH reception starting time (e.g., the PDSCH reception starting time for the same {serving cell, PDCCH MO}-pair),

[0233] - second in ascending order of serving cell index (e.g., scheduled serving cell index), and

[0234] - third in ascending order of PDCCH MO index.

[0235] In some examples, the first DAI may be a C-DAI (Counter-DAI). The first DAI may indicate an accumulative number of at least one of DCI scheduling PDSCH reception(s), DCI format(s) indicating SPS PDSCH release (deactivation), or DCI indicating secondary cell dormancy. For example, the accumulative number may be an accumulative number up to the current serving cell and / or the current time unit. For example, the C-DAI may also indicate: an accumulative number of {serving cell, time unit} pair(s) scheduled by PDCCH(s) up to the current time unit within a time window (which may also include a number of PDCCHs (e.g., PDCCHs indicating SPS release and / or PDCCHs indicating secondary cell dormancy)); or an accumulative number of PDCCH(s) up to the current time unit; or an accumulative number of PDSCH transmission(s) up to the current time unit; or an accumulative number of {serving cell, time unit} pair(s) in which PDSCH transmission(s) related to PDCCH(s) (e.g., scheduled by the PDCCH(s)) and / or PDCCH(s) (e.g., PDCCH indicating SPS release and / or PDCCH indicating secondary cell dormancy) is present, up to the current serving cell and / or the current time unit; or an accumulative number of PDSCH(s) with corresponding PDCCH(s) and / or PDCCHs (e.g., PDCCHs indicating SPS release and / or PDCCHs indicating secondary cell dormancy) already scheduled by a base station up to the current serving cell and / or the current time unit; or an accumulative number of PDSCHs (the PDSCHs are PDSCHs with corresponding PDCCHs) already scheduled by the base station up to the current serving cell and / or the current time unit; or an accumulative number of time units with PDSCH transmissions (the PDSCHs are PDSCHs with corresponding PDCCHs) already scheduled by the base station up to the current serving cell and / or the current time unit. The order of each bit in the HARQ-ACK codebook corresponding to at least one of PDSCH reception(s), DCI format(s) indicating SPS PDSCH release (deactivation), or DCI indicating secondary cell dormancy may be determined by the time when the first DAI is received and the information of the first DAI.

[0236] In some examples, the second DAI may indicate a total number of at least one of all PDSCH receptions, DCI indicating SPS PDSCH release (deactivation), or DCI format(s) indicating secondary cell dormancy. For example, the total number may be a total number of all serving cells up to the current time unit. For example, the T-DAI may refer to: a total number of {serving cell, time unit} pairs scheduled by PDCCH(s) up to the current time unit within a time window (which may also include a number of PDCCHs for indicating SPS release); or a total number of PDSCH transmissions up to the current time unit; or a total number of {serving cell, time unit} pairs in which PDSCH transmission(s) related to PDCCH(s) (e.g., scheduled by the PDCCH) and / or PDCCH(s) (e.g., a PDCCH indicating SPS release and / or a PDCCH indicating secondary cell dormancy) is present, up to the current serving cell and / or the current time unit; or a total number of PDSCHs with corresponding PDCCHs and / or PDCCHs (e.g., PDCCHs indicating SPS release and / or PDCCHs indicating secondary cell dormancy) already scheduled by a base station up to the current serving cell and / or the current time unit; or a total number of PDSCHs (the PDSCHs are PDSCHs with corresponding PDCCHs) already scheduled by the base station up to the current serving cell and / or the current time unit; or a total number of time units with PDSCH transmissions (e.g., the PDSCHs are PDSCHs with corresponding PDCCHs) already scheduled by the base station up to the current serving cell and / or the current time unit.

[0237] In the following examples, the first DAI as the C-DAI and the second DAI as the T-DAI are taken as an example (but not limited thereto) for illustration.

[0238] Tables 1 and 2 show a correspondence between the DAI field and VT-DAI,mor VC-DAI,c,mor . Numbers of bits of the C-DAI and T-DAI are limited.

[0239] For example, in case that a C-DAI or T-DAI in a DCI format is represented with 2 bits, the value of the C-DAI or T-DAI in the DCI format may be determined by equations in Table 1. VT-DAI,mor is the value of the T-DAI in the DCI format received in a PDCCH Monitoring Occasion (MO) m, and VC-DAI,c,mis the value of the C-DAI in the DCI format for a serving cellcreceived in the PDCCH monitoring occasionm. Both VT-DAI,mand VC-DAI,c,mare related to a number of bits of the DAI field in the DCI format. MSB is the most significant bit and LSB is the least significant bit.

[0240] MSB, LSB of DAI FieldVT-DAI,mor VC-DAI,c,mor Y0, 01(Y-1)mod4-1=10, 12(Y-1)mod4-1=21, 03(Y-1)mod4-1=31, 14(Y-1)mod4-1=4

[0241] For example, when the C-DAI or T-DAI is 1, 5 or 9, as shown in Table 1, all of the DAI field are indicated with "00", and the value of VT-DAI,mor VC-DAI,c,mis represented as "1" by the equation in Table 1. Y may represent the value of the DAI corresponding to the number of DCI formats actually transmitted by the base station (the value of the DAI before conversion by the equation in the table).

[0242] For example, in case that the C-DAI or T-DAI in the DCI format is 1 bit, values greater than 2 may be represented by equations in Table 2.

[0243] DAI FieldVT-DAI,mor VC-DAI,c,mY01(Y-1)mod2+1=112(Y-1)mod2+1=2

[0244] In some implementations, the UE may generate HARQ-ACK information bits in a PUCCH according to pseudo code 1. For example, if the UE transmits HARQ-ACK information in a PUCCH (for example, a PUCCH for any PUCCH format) in slot n, the UE determines HARQ-ACK information bits according to pseudo code 1, where OACKis the total number of HARQ-ACK information bits.

[0245] [Pseudo code 1]

[0246]

[0247]

[0248]

[0249]

[0250] In some implementations, for a HARQ-ACK codebook in a PUSCH, the UE may set after completing the c and m loops of generating the HARQ-ACK codebook in pseudo-code 1, where is UL DAI, the value of which may be determined according to Table 1 or 2.

[0251] [HARQ feedback mode]

[0252] In some implementations, whether to feed back HARQ-ACK information may be configured by higher layer parameters or dynamically indicated by a DCI. The mode of feeding back (or reporting) the HARQ-ACK information (HARQ-ACK feedback mode or HARQ-ACK reporting mode) may also be at least one of the following modes.

[0253] - HARQ-ACK feedback mode 1: transmitting ACK or NACK (ACK / NACK). For example, for a PDSCH reception, if the UE decodes a corresponding transport block (TB) correctly, the UE transmits ACK; and / or, if the UE does not decode the corresponding transport block correctly, the UE transmits NACK. For example, a HARQ-ACK information bit of the HARQ-ACK information provided according to the HARQ-ACK feedback mode 1 is an ACK value or a NACK value.

[0254] - HARQ-ACK feedback mode 2: transmitting NACK only (NACK-only). For example, for a PDSCH reception, if the UE decodes the corresponding transport block correctly, the UE does not transmit the HARQ-ACK information; and / or, if the UE does not decode the corresponding transport block correctly, the UE transmits NACK. For example, at least one HARQ-ACK information bit of the HARQ-ACK information provided according to the HARQ-ACK feedback mode 2 is a NACK value. For example, for the HARQ-ACK feedback mode 2, the UE does not transmit a PUCCH that would include only HARQ-ACK information with ACK values.

[0255] For the PDSCH reception of a HARQ process, if the UE is configured not to feed back HARQ-ACK information, the HARQ-ACK codebook does not include HARQ-ACK information for the PDSCH reception.

[0256] [Channel collision]

[0257] In some implementations, a PUSCH conflicting / colliding with other physical channel(s) may be at least one of:

[0258] - a PUSCH overlapping in time domain with PUCCH(s) and / or PDSCH(s) and / or PDCCH(s) on a same serving cell;

[0259] - in case that simultaneous transmission for PUSCH is not configured, a PUSCH overlapping in time domain with other PUSCH(s) on a same serving cell;

[0260] - in case that the simultaneous transmission for PUSCH is configured, a PUSCH overlapping in time domain with another PUSCH, on a same serving cell, with a same value of a control resource set (CORESET) pool index parameter (e.g., coresetPoolIndex); or

[0261] - a PUSCH overlapping in time domain with a PUCCH. For example, a PUSCH overlaps in time domain with a PUCCH on a different serving cell, and / or the serving cell does not support simultaneous transmission of the PUSCH and the PUCCH.

[0262] In some implementations, a PDSCH conflicting / colliding with other physical channel(s) may be at least one of:

[0263] - a PDSCH overlapping in time domain with other PUSCH(s) and / or PUCCH(s) and / or PDSCH(s) on a same serving cell;

[0264] - in case that simultaneous reception for PDSCH is not configured (for example, the UE is not configured with different values of the CORESET pool index parameter (e.g., coresetPoolIndex)), a PDSCH overlapping in time domain with other PUSCH(s) on a same serving cell;

[0265] - in case that simultaneous transmission for PDSCH is configured (for example, the UE is configured with a PDCCH configuration parameter (e.g.,PDCCH-Config) including a CORESET parameter (e.g., ControlResourceSet) with different values of the CORESET pool index parameter (e.g., coresetPoolIndex)), a PDSCH overlapping in time domain with another PDSCH on a same serving cell with a same value of the CORESET pool index parameter (e.g., coresetPoolIndex); or

[0266] - a PDSCH overlapping in both time domain and frequency domain with a PDCCH on a same serving cell.

[0267] In some implementations, a PUCCH conflicting / colliding with other physical channel(s) may be at least one of:

[0268] - a PUCCH overlapping in time domain with other PUCCH(s) and / or PUSCH(s); or

[0269] - a PUCCH overlapping in time domain with other PDSCH(s) on a same serving cell.

[0270] In some implementations, a PDCCH conflicting / colliding with other physical channel(s) may be at least one of:

[0271] - a PDCCH overlapping in time domain with other PUSCH(s) and / or PUCCH(s) on a same serving cell; or

[0272] - a PDCCH overlapping in both time domain and frequency domain with other PDSCH(s) on a same serving cell.

[0273] In the description of the example embodiments of the disclosure, "a set of overlapping channels" may be understood as that each channel of the set of overlapping channels overlaps (or collides) with at least one of channels in the set except this channel. The channels may include one or more PUCCHs and / or one or more PUSCHs. For example, "a set of overlapping channels" may include "a set of overlapping PUCCHs and / or PUSCHs". As a specific example, when a first PUCCH overlaps with at least one of a second PUCCH and a third PUCCH, the second PUCCH overlaps with at least one of the first PUCCH and the third PUCCH, and the third PUCCH overlaps with at least one of the first PUCCH and the second PUCCH, the first PUCCH, the second PUCCH and the third PUCCH constitute a set of overlapping channels (PUCCHs). For example, the first PUCCH overlaps with the second PUCCH and the third PUCCH, and the second PUCCH and the third PUCCH do not overlap.

[0274] It should be noted that, in the description of the example embodiments of the disclosure, "resolving overlapping channels" may be understood as resolving the collision of overlapping channels. For example, when a PUCCH overlaps with a PUSCH, resolving the overlapping or collision may include multiplexing UCI of the PUCCH in the PUSCH, or may include transmitting the PUCCH or PUSCH with a higher priority. For another example, when a PUCCH overlaps with one or another PUCCH, resolving the overlapping or collision may include multiplexing UCI in a PUCCH, or may include transmitting the PUCCH with a higher priority. For yet another example, when two PUSCHs on a same serving cell overlap, resolving the overlapping or collision may include transmitting a PUSCH with a higher priority of the two PUSCHs. "Resolving overlapping channels", "resolving the overlapping among channels", "determining the overlapping among channels" and "determining overlapping channels" may be used interchangeably.

[0275] It should be noted that, unless the context clearly indicates otherwise, all or one or more of the methods, steps or operations described in the example embodiments of the disclosure may be specified by protocols and / or configured by higher layer signaling and / or indicated by dynamic signaling. The dynamic signaling may be a PDCCH and / or DCI and / or a DCI format. For example, a SPS PDSCH and / or CG PUSCH may be dynamically indicated in a corresponding activated DCI / DCI format / PDCCH. All or one or more of the described methods, steps and operations may be optional. For example, if a certain parameter (e.g., parameter X) is configured, the UE performs a certain approach (e.g., approach A), otherwise (if the parameter, e.g., parameter X, is not configured), the UE performs another approach (e.g., approach B). Unless otherwise specified, the parameters in the example embodiments of the disclosure may be higher layer parameters. For example, the higher layer parameters may be parameters configured or indicated by higher layer signaling (e.g., RRC signaling).

[0276] It should be noted that, in the description of the example embodiments of the disclosure, a PCell (Primary Cell) or PSCell (Primary Secondary Cell) in the example embodiments of the disclosure may be used interchangeably with a cell having a PUCCH. A serving cell may be used interchangeably with a cell.

[0277] It should be noted that, in the description of the example embodiments of the disclosure, methods for downlink in the example embodiments of the disclosure may also be applicable to uplink, and methods for uplink may also be applicable to downlink. For example, a PDSCH may be replaced with a PUSCH, a SPS PDSCH may be replaced with a CG PUSCH, and downlink symbols may be replaced with uplink symbols, so that methods for downlink may be applicable to uplink.

[0278] It should be noted that, in the description of the example embodiments of the disclosure, methods applicable to scheduling multiple PDSCHs / PUSCHs in the example embodiments of the disclosure may also be applicable to a PDSCH / PUSCH transmission with repetitions. For example, a PDSCH / PUSCH of multiple PDSCHs / PUSCHs may be replaced by a repetition of multiple repetitions of the PDSCH / PUSCH transmission.

[0279] It should be noted that, in the description of the example embodiments of the disclosure, "configured with and / or indicated a transmission with repetitions" may be understood that a number of the repetitions of the transmission is greater than 1. For example, "configured with and / or indicated a PUCCH transmission with repetitions" may be understood that "the PUCCH transmission is repeated on more than one slot / subslot". "Not configured with and / or indicated a transmission with repetitions" may be understood that a number of the repetitions of the transmission is equal to 1. For example, "not configured with and / or indicated a PUCCH transmission with repetitions" may be understood that "a number of the repetitions of the PUCCH transmission is equal to 1". For example, the UE may be configured with a parameter related to a number of repetitions of a PUCCH transmission; when the parameter is greater than 1, it may mean that the UE is configured with a PUCCH transmission with repetitions, and the UE may repeat the PUCCH transmission on time units (e.g., slots); when the parameter is equal to 1, it may mean that the UE is not configured with a PUCCH transmission with repetitions. For example, the PUCCH transmission with repetitions may include only one type of UCI. If the PUCCH is configured with repetitions, in the description of the example embodiments of the disclosure, a repetition of the multiple repetitions of the PUCCH may be used as a PUCCH (or a PUCCH resource), or all of the repetitions of the PUCCH may be used as a PUCCH (or a PUCCH resource), or a specific repetition of the multiple repetitions of the PUCCH may be used as a PUCCH (or a PUCCH resource).

[0280] It should be noted that, in the description of the example embodiments of the disclosure, a PDCCH and / or DCI and / or a DCI format schedules multiple PDSCHs / PUSCHs, which may be multiple PDSCHs / PUSCHs on a same serving cell and / or multiple PDSCHs / PUSCHs on different serving cells.

[0281] It should be noted that, in the description of the example embodiments of the disclosure, multiple manners / methods described in the disclosure may be combined in any order. In a combination, a manner / method may be performed one or more times, or a m manner / method may not be performed. In addition, at least one step / operation in one manner / method of multiple modes / methods may be combined with one or more steps / operations in other manner / method(s) in the example embodiments of the disclosure to form new embodiments. Steps / operations in a combination may be performed one or more times. When a manner / method or a manner / method combination is performed, one or more steps / operations of the manner / method or the manner / method combination may be omitted, or other associated steps / operations (e.g., one or more steps / operations in other associated modes / methods) may be additionally performed.

[0282] It should be noted that, steps / operations of manners / methods of the disclosure may be implemented in any order.

[0283] It should be noted that, in the description of the example embodiments of the disclosure, "canceling a transmission" may mean canceling the transmission of the entire uplink channel and / or cancelling the transmission of a part of the uplink channel.

[0284] It should be noted that, in the description of the example embodiments of the disclosure, "an order from small to large" (e.g., an ascending order) may be replaced by "an order from large to small" (e.g., a descending order), and / or "an order from large to small" (e.g., a descending order) may be replaced by "an order from small to large" (e.g., an ascending order).

[0285] It should be noted that, in the description of the example embodiments of the disclosure, a PUCCH / PUSCH carrying / including / with A may be understood as a PUCCH / PUSCH only carrying / including / with A, and may also be understood as a PUCCH / PUSCH carrying / including / with at least A.

[0286] It should be noted that, in the description of the example embodiments of the disclosure, "slot" may be replaced by "subslot" or "time unit".

[0287] It should be noted that, in the description of the example embodiments of the disclosure, a time interval (or a time unit interval) between a first physical channel and a second physical channel may be understood as a time interval (or a time unit interval) between an end position (or an end symbol) of the first physical channel and a starting position (or a starting symbol) of the second physical channel, where the first physical channel is earlier than the second physical channel. "The time interval between the first physical channel and the second physical channel is less than a predefined time," "the first physical channel is a time (which is less than the predefined time) earlier than the second physical channel," and "the first physical channel is a time (which is within the predefined time) earlier than the second physical channel" may be used interchangeably; 뱓he time interval between the first physical channel and the second physical channel is greater a predefined time", "the first physical channel is a time (which is greater than the predefined time) earlier than the second physical channel", and "the first physical channel is a time (which is not within the predefined time) earlier than the second physical channel" may be used interchangeably. Or, a time interval (or a time unit interval) between a first physical channel and a second physical channel may be understood as a time interval (or time unit interval) between a time unit in which the first physical channel is located and a time unit in which the second channel is located. The time unit where the physical channel is located may be understood as a time unit that overlaps with the end position (or end symbol) of the physical channel or a time unit that overlaps with the starting position (or starting symbol) of the physical channel.

[0288] It should be noted that, in the description of the example embodiments of the disclosure, "performing a predefined method (or step) if a predefined condition is satisfied" and "not performing the predefined method (or step) if the predefined condition is not satisfied" may be used interchangeably.

[0319] In some examples, the UE may be configured or provided with an SRS resource set index parameter (e.g., SRS_resource_set_index) with two different values (e.g., value 0 and value 1). The first SRS resource set (the SRS resource set index parameter value is equal to 0) may correspond to a CORESET pool index parameter with a value of 0, and the other SRS resource set (SRS resource set index parameter value is equal to 1) may correspond to the CORESET pool index parameter with a value of 1.

[0320] In embodiments of the disclosure, the term "panel" may refer to a group of antenna ports or an antenna group. An uplink transmission configuration indicator (TCI) of each antenna panel may be used to indicate a beam for the antenna panel, which may be a beam associated with the indicated reference signal ID. An SRS set ID may be used to indicate the antenna panel ID, where each antenna panel is associated with one SRS set.

[0321] In operation S710, the UE may receive first information from a base station, where the first information may be downlink control signaling. For example, the first information may be configuration information carried through higher layer signaling. The first information may be used to indicate configuration information related to second information and / or fourth information, where the second information may indicate (or notify) that the UE would transmit (e.g., the UE is to transmit; the UE intends to transmit; the UE requests to transmit; the UE initiates transmission; or the UE is to transmit due to various events or conditions) the fourth information, or, the second information may indicate whether the UE would transmit the fourth information; the fourth information may include a report (or transmission) of beam related information. The second information may be a new UCI type different from the existing UCI type. For example, the second information may be a UCI type different from SR, LRR, HARQ-ACK, or CSI. Or, the second information may be a specific SR. In some implementations, the second information may include positive second information or negative second information. For example, the positive second information may indicate that the UE would transmit (e.g., the UE is to transmit; the UE intends to transmit; the UE requests to transmit; the UE initiates transmission; or the UE is to transmit due to various events or conditions) the fourth information. For example, the negative second information may indicate that the UE does not transmit the fourth information.

[0322] In some implementations, the fourth information may further include at least one of uplink data, HARQ-ACK information, CSI report, or other UCI information.

[0323] In some implementations, the beam related information may be at least one of:

[0324] - CSI report

[0325] - beam management information

[0326] - beam measurement information

[0327] - BFR (beam failure recovery)

[0328] As some examples, the beam management information may refer to information related to beam management.

[0329] As some examples, the beam measurement information may refer to information related to beam measurement.

[0330] As some examples, the BFR may refer to information related to a BFR procedure.

[0331] Note that the above-described "CSI report", "beam management information", "beam measurement information", and "BFR" are only examples of beam-related information. Example embodiments of the disclosure are equally applicable to other beam-related information.

[0332] Note that although the “CSI report”, “beam management information”, “beam measurement information”, and “BFR” are described in a separate manner, it will be understood that one of them may be included in the other as the fourth information. For example, at least one of “beam management information”, “beam measurement information”, and “BFR” may be included in the CSI reports as the fourth information. Accordingly, in the example embodiments of the disclosure, the CSI reports may also refer to CSI reports including at least one of beam management information, beam measurement information, or BFR.

[0333] In the following example embodiments of the disclosure, for convenience of explanation, it is possible to describe a CSI report as an example of beam-related information. However, it will be understood that the "CSI report" may be replaced with other beam-related information.

[0334] In some implementations, the beam-related information may be UE-initiated beam-related information. For example, the beam related information may be a CSI report initiated by the UE.

[0335] In some implementations, the fourth information may include a report (or transmission) of one or more beam related information. For example, the fourth information may include a report (or transmission) of one or more beam related information in a time unit and / or in a PUCCH or PUSCH.

[0336] The UE transmits the second information in operation S730. For example, the UE may transmit the second information in an uplink time unit.

[0337] Optionally, in operation S710, the UE may further receive third information, where the third information may indicate the number (or the number of types, or the number of configurations) M of the fourth information (e.g., the number (or the type) M of the fourth information in a time unit), or the third information may indicate the number (or the number of types, or the number of configurations) M of the fourth information transmitted by the UE simultaneously (e.g., in a same time or time unit). Here, M may be a non-negative integer or a positive integer. For example, M may be 1, 2, 3, or 4. If the UE is not configured with the third information, the UE would report (or transmit) one beam related information (information related to a beam) in a time unit. The one beam related information may be beam measurement information of a beam set including the beam. And / or, the one beam related information may be beam measurement information of a beam set associated with the beam. The UE may report the maximum value of M through a UE capability. For example, the maximum value of M may be 1, 2, or 4.

[0338] Optionally, in operation S710, the UE may further receive thirteenth information, where the thirteenth information may be configuration information related to one or more second information. For example, the thirteenth information may be a configuration information list related to the second information, where one element in the list corresponds to the configuration information related to one second information. The number of elements in the list may be M. The elements in the thirteenth information may be in one-to-one correspondence with the elements in fifth information. The number of elements in the thirteenth information may also be M', where M' may be a non-negative integer or a positive integer. For example, M' may be 1, 2, 3, or 4, among others. One or more elements in the thirteenth information may correspond to one element in the fifth information. One element in the thirteenth information may correspond to one or more elements in the fifth information. For example, one or more associated elements (e.g., element indexes) in the thirteenth information may be configured for each element in the fifth information. Or, one or more associated elements (e.g., element indexes) in the fifth information may be configured for each element in the thirteenth information.

[0339] Optionally, in operation S710, the UE may further receive the fifth information, where the fifth information may be configuration information related to one or more fourth information. For example, the fifth information may be a configuration information list related to the fourth information, where one element in the list corresponds to the configuration information related to one fourth information. The number of elements in the list may be M.

[0340] In some implementations, the UE may be configured with N sixth information, each of which may correspond to configuration information of one second information and / or fourth information. Or, the UE may be configured with a sixth information list. Here, N may be a positive integer. For example, N may be 1, 2, 3, or 4. The maximum value of N may be 1, 2, or 4. The UE may report the maximum value of N through a UE capability. In some implementations, N may be equal to M. The sixth information may be in one-to-one correspondence with the second information and / or the fourth information. In some implementations, N may be less than M. One sixth information may correspond to the configuration information of one or more second information and / or fourth information. Optionally, the first information may include the sixth information.

[0341] In some implementations, the sixth information may include at least one of the following:

[0342] - A first PUCCH resource, e.g., a first PUCCH resource index. For example, the first PUCCH resource index may be the parameter PUCCH-ResourceId. The first PUCCH resource may be a PUCCH resource carrying the second information. Or, the first PUCCH resource may be a PUCCH resource carrying the second information and the fourth information.

[0344] - A second PUCCH resource, e.g., a second PUCCH resource index. For example, the second PUCCH resource index may be the parameter PUCCH-ResourceId. The second PUCCH resource may be a PUCCH resource carrying the fourth information.

[0345] - A second BWP index. The second BWP index may be the index of a BWP where the second PUCCH resource is located (or, a BWP corresponding to the second PUCCH resource).

[0346] - A third BWP index. The third BWP index may be the index of a BWP where the first PUCCH resource and the second PUCCH resource are located (or, a BWP corresponding to the first PUCCH resource and the second PUCCH resource).

[0347] - A PUSCH resource. The PUSCH resource may be a PUSCH resource carrying the fourth information. Or, the PUSCH resource may be a PUSCH resource carrying the second information and the fourth information. The PUSCH resource may be a CG PUSCH resource. For example, a CG PUSCH configuration index parameter, such as the parameter ConfiguredGrantConfigIndex, may be configured.

[0348] - A serving cell index. The serving cell index is the index of a serving cell where the PUSCH is transmitted.

[0349] - A fourth BWP index. The fourth BWP index is the index of a BWP where the PUSCH resource is located (or, a BWP corresponding to the PUSCH resource). Or, the fourth BWP index is the index of a BWP on a serving cell where the PUSCH resource is located (or, corresponding to the PUSCH resource).

[0350] - An index corresponding to the second information (or an index of the second information), for example, indexes corresponding to one or more second information.

[0351] - An index corresponding to the fourth information (or an index of the fourth information), for example, indexes corresponding to one or more fourth information.

[0352] - SR information corresponding to the second information, for example, the index of an SR (e.g., parameter schedulingRequestID).

[0353] - SR resource information corresponding to the second information, for example, the index of an SR resource (e.g., parameter schedulingRequestResourceId).

[0354] - A first RS index. The first RS index may be an RS index corresponding to the second information. For example, the first RS index may be the parameter CSI-ResourceConfigId.

[0355] - A second RS index. The second RS index may be the index of an RS corresponding to the fourth information. For example, the second RS index may be the parameter CSI-ResourceConfigId.

[0356] - The index of a CSI report configuration corresponding to the fourth information, for example, the parameter CSI-ReportConfigId.

[0357] - A first timer or a first time interval. For example, the first timer or first time interval may be a time interval (or a minimum time interval) of two second information transmissions (e.g., two adjacent second information transmissions). For example, the first timer may be a prohibit second information transmission timer. For example, when the first timer is running, the second information is not transmitted; and / or the second information may be transmitted when the first timer expires or is not running.

[0358] In some implementations, one sixth information may correspond to configuration information of a pair or a set of second information and fourth information. Here, the pair of second information and fourth information includes one second information and one fourth information that are associated with each other. The set of second information and fourth information includes one or more second information and one fourth information that is associated with the one or more second information, or one second information and one or more fourth information that are associated with the one second information.

[0359] Note that the first RS may be an RS corresponding to the current beam (or TCI), the second RS may be an RS corresponding to the candidate beam (or TCI), or the second RS may be the RS corresponding to the current beam (or TCI) and the candidate beam (or TCI).

[0360] In some implementations, for a first RS (or first RS index), the sixth information may configure one or more second RSs (or second RS indexes). For example, the sixth information may configure a set of second RSs, where the set of second RSs includes one or more second RSs. The one or more second RS may include the first RS. For example, the first (or last) RS in the set of second RSs is the first RS.

[0361] In some implementations, a list of second RS sets may be configured, where each element in the list of second RS sets is a second RS set.

[0362] In some implementations, a list of first RSs and a list of second RS sets may be configured, where an element in the list of first RSs is a first RS. The elements of the list of first RSs are in one-to-one correspondence with the elements in the list of second RS sets; for example, the set of second RSs corresponding to a first RS in the list of first RSs is the set of second RSs with the same index in the list of second RS sets.

[0363] In some implementations, the UE may be configured with ninth information including configuration information related to tenth information. The tenth information is used to indicate a wake-up of one or more cells, and / or a wake-up request (e.g., an uplink wake-up request), and / or a request for a first predefined downlink channel (e.g., on-demand SSB / SIB1 / PDCCH / PSS (primary synchronization signal) / SSS (secondary synchronization signal)). In some cases, the UE may transmit the tenth information. It is possible to reuse the configuration method of the sixth information in the embodiments of the disclosure to configure the ninth information, and / or reuse the method of the configuration information related to the second information and / or the fourth information to configure the configuration information related to the tenth information, and / or reuse the transmission of the second information and / or the fourth information to transmit the tenth information. For example, "sixth information" may be replaced with "ninth information" in the embodiments of the disclosure, and / or "second information" may be replaced with "tenth information" in the embodiments of the disclosure, and / or "fourth information" may be replaced with "tenth information" in the embodiments of the disclosure, and / or "second information and / or fourth information" may be replaced with "tenth information" in the embodiments of the disclosure. The tenth information may be a UCI type different from SR, LRR, HARQ-ACK and CSI. Or, the tenth information may be a specific SR. In the example embodiments of the disclosure, the first predefined downlink channel may include at least one of the following: on-demand SSB, SIB1, PDCCH, PSS, or SSS.

[0364] In some implementations, the tenth information may include positive tenth information or negative tenth information. For example, the positive tenth information may indicate a wake-up of one or more cells, and / or a wake-up request (e.g., an uplink wake-up request), and / or a request for a first predefined downlink channel (e.g., an on-demand SSB / SIB1 / PDCCH). For example, the negative tenth information may indicate one or more cells not to wake-up, and / or not requesting a wake-up (e.g., not requesting an uplink wake-up), and / or not requesting a first predefined downlink channel (e.g., an on-demand SSB / SIB1 / PDCCH). That is, the negative tenth information may indicate that the UE does not request one or more cells to wake up, and / or does not request the first predefined downlink channel.

[0365] In some implementations, the ninth information may include at least one of the following:

[0366] - A third PUCCH resource, e.g., a third PUCCH resource index. For example, the third PUCCH resource index may be the parameter PUCCH-ResourceId. The third PUCCH resource may be a PUCCH resource carrying the tenth information.

[0367] - A fifth BWP index. The fifth BWP index may be the index of a BWP where the third PUCCH resource is located (or, corresponding to the third PUCCH resource).

[0368] - SR information corresponding to the tenth information, for example, the index of an SR (e.g., parameter schedulingRequestID).

[0369] - SR resource information corresponding to the tenth information, for example, the index of a SR resource (e.g., parameter schedulingRequestResourceId).

[0370] - A second timer or a second time interval. For example, the second timer or second time interval may be a time interval (or a minimum time interval) of two transmissions of the tenth information (e.g., two adjacent tenth information transmissions). For example, the second timer may be a prohibit tenth information transmission timer. For example, when the second timer is running, the tenth information is not transmitted.

[0371] - PRACH information corresponding to the tenth information.

[0372] - Message A (MSG A) information (e.g., for random access) corresponding to the tenth information.

[0373] - Information of the first predefined downlink channel corresponding to the tenth information, for example, SSB or SIB1 corresponding to the tenth information.

[0374] - Serving cell information corresponding to the tenth information, for example, an index of a serving cell (e.g., physical cell ID (PCI) or ServCellIndex).

[0375] In some implementations, a parameter may be configured in a CG PUSCH configuration parameter (e.g., ConfiguredGrantConfig), where the parameter is used to indicate whether a CG PUSCH is used for the second information and / or the fourth information, and / or the parameter is used to indicate the corresponding second information and / or fourth information configuration (e.g., second information and / or fourth information configuration index) and / or the parameter is used to indicate the corresponding first PUCCH resource. In this way, the PUSCH resource for transmitting the second information and / or the fourth information can be clearly defined, and the reliability of uplink transmission can be improved. Note that the "CG PUSCH configuration parameter (e.g., ConfiguredGrantConfig)" in the method may be replaced with the "PUCCH resource parameter (e.g., PUCCH-Resource)."

[0376] In some implementations, a first parameter list may be configured for configuring PUCCH resources corresponding to the second information. For example, the elements in the first parameter list are PUCCH resource indexes (e.g., PUCCH-ResourceId), and the index of each element in the first parameter list corresponds to the second information configuration of the same index. For another example, one element in the first parameter list includes a PUCCH resource index (e.g., PUCCH-ResourceId) and a second information configuration index. The second information configuration configured by the one element is carried by the PUCCH resource configured by the one element. The first parameter list may be configured in a PUCCH configuration parameter (e.g., parameter PUCCH-Config). In this way, the PUCCH resource for transmitting the second information can be clearly defined, and the reliability of uplink transmission can be improved. Note that the first PUCCH resource index in the embodiments of the disclosure may be an index corresponding to an element (or resource) in the first parameter list. Note that "second information" may be replaced with "tenth information".

[0377] In some implementations, a second parameter list may be configured for configuring PUCCH resources corresponding to the second information and / or the fourth information. For example, the elements in the second parameter list are PUCCH resource indexes (e.g., PUCCH-ResourceId), and the index of each element in the second parameter list corresponds to the second information and / or fourth information configuration of the same index. For another example, one element in the second parameter list includes a PUCCH resource index (e.g., PUCCH-ResourceId) and a second information and / or fourth information configuration index. The second information and / or the fourth information configuration configured by the one element is carried by the PUCCH resource configured by the element. The second parameter list may be configured in a PUCCH configuration parameter (e.g., parameter PUCCH-Config). In this way, the PUCCH resource for transmitting the second information and / or the fourth information can be clearly defined, and the reliability of uplink transmission can be improved. Note that the second PUCCH resource index in the embodiments of the disclosure may be an index corresponding to an element (or resource) in the second parameter list.

[0378] In some implementations, a third parameter list may be configured for configuring PUSCH configurations, e.g., CG PUSCH configurations, corresponding to the second information and / or the fourth information. For example, the elements in the third parameter list are CG PUSCH configuration indexes (e.g., ConfiguredGrantConfigIndex) and / or a serving cell index, the index of each element in the third parameter list corresponding to the second information and / or fourth information configuration of the same index. For another example, one element in the third parameter list includes a CG PUSCH configuration index (e.g., ConfiguredGrantConfigIndex) and / or a serving cell index and a second information and / or a fourth information configuration index. The second information and / or the fourth information configuration configured by the one element is carried by the CG PUSCH configuration (e.g., the CG PUSCH configuration on the configured serving cell) configured by the element. In this way, the PUCCH resource for transmitting the second information and / or the fourth information can be clearly defined, and the reliability of uplink transmission can be improved. Note that "serving cell index" may be replaced with "BWP index" or "serving cell index and BWP index". In this case, the second information and / or the fourth information configuration configured by the one element in the third parameter list is carried by the CG PUSCH configuration of the BWP on the configured serving cell configured by the element. Note that the PUSCH resource configured by the sixth information in the embodiments of the disclosure may be an index corresponding to an element (or resource) in the third parameter list.

[0379] In some implementations, the elements in the first parameter list may be in one-to-one correspondence with the elements in the second parameter list or the elements in the third parameter list, e.g., an element of an index in the first parameter list corresponds to an element in the second parameter list of the same index or an element in the third parameter list of the same index.

[0380] In some implementations, an element in the first parameter list may correspond to one or more elements in the second parameter list or one or more elements in the third parameter list; e.g., one or more elements in the second parameter list or one or more elements in the third parameter list may be configured for the corresponding element in the first parameter list; e.g., the element indexes in the second parameter list or the element indexes in the third parameter list may be configured.

[0381] In some implementations, an element in the second parameter list or an element in the third parameter list may correspond to one or more elements in the first parameter list; e.g. an element in the second parameter list or an element in the third parameter list may be configured for the corresponding one or more elements in the first parameter list; e.g. the element indexes in the first parameter list may be configured.

[0382] Note that "element index" in embodiments of the disclosure may be replaced with "PUCCH resource index" or "PUSCH resource index".

[0383] In this way, the correspondence between the transmitted second information and the transmitted fourth information can be clearly defined, and the reliability of uplink transmission can be improved.

[0384] In some implementations, the index of the second information and / or the fourth information configuration may be configured in a CG PUSCH configuration parameter (e.g., parameter ConfiguredGrantConfig). For example, the second information and / or the fourth information corresponding to the index is carried by the CG PUSCH configuration. In this way, the PUSCH resource for transmitting the second information and / or the fourth information can be clearly defined, and the reliability of uplink transmission can be improved.

[0385] In some implementations, a fourth parameter list for configuring SR or SR configurations or SR resources corresponding to the second information may be configured. For example, an element in the fourth parameter list is the index of an SR or the index of an SR configuration (e.g., schedulingRequestID) or the index of an SR resource (e.g., schedulingRequestResourceId), the index of each element in the fourth parameter list corresponding to the second information configuration of the same index. For another example, one element in the fourth parameter list includes the index of an SR or SR configuration (e.g., pucch-ResourceId) or the index of an SR resource (e.g., schedulingRequestResourceId) and the index of a second information configuration. The second information configuration configured by the one element is carried by the SR resource corresponding to the SR or SR configuration configured by the element. In this way, the PUCCH resource for transmitting the second information and / or the fourth information can be clearly defined, and the reliability of uplink transmission can be improved. Note that "second information" may be replaced with "tenth information".

[0386] In some implementations, the PUCCH resource carrying the second information or the tenth information may be PUCCH format 0 and / or PUCCH format 1.

[0387] In some implementations, a fifth parameter list for configuring first cycle shifts corresponding to the second information may be configured. For example, the index of each element in the fifth parameter list corresponds to the second information configuration of the same index. Or, the index of each element in this fifth parameter list corresponds to the second information configuration of the same index plus 1. For example, the first cyclic shift of index 0 in the fifth parameter list corresponds to the second information configuration of index 1. For another example, one element in the fifth parameter list includes the first cyclic shift and the second information configuration index. The cyclic shift of PUCCH format 0 carrying the second information configured by the one element is determined by the first cyclic shift. For example, the cyclic shift of PUCCH format 0 carrying the second information configured by the one element may be the sum of the initial cyclic shift of the PUCCH resource and the first cyclic shift corresponding to the second information configuration. In this way, the cyclic shift of PUCCH format 0 for transmitting the second information can be clear defined, and the reliability of uplink transmission can be improved. Note that "second information" may be replaced with "tenth information".

[0388] In some implementations, the correspondence of the content (e.g., indication) of the second information to the fourth information configuration may be specified by protocols. In some implementations, the second information of "0" may correspond to the fourth information configuration of index 0 and the second information "1" may correspond to the fourth information configuration of index 1. For example, the method may be used for PUCCH format 1 in case of BPSK modulation. In some implementations, the second information of "00" may correspond to the fourth information configuration of index 0, and the second information of "01" may correspond to the fourth information configuration of index 1. The second information of "10" may correspond to the fourth information configuration of index 2, and the second information "11" may correspond to the fourth information configuration of index 3. For example, the method may be used for PUCCH format 1 in case of QPSK modulation. In some implementations, the second information may be included in CSI part 1. The fourth information may be included in CSI part 2. For example, P bits may be newly added in CSI part 1 to indicate twelfth information. Here, P may be a positive integer. P may be specified by protocol, or configured by higher layer signaling. P may also be determined according to the number or type M of the fourth information configurations. For example, P = , where the operator represents ceiling operation.

[0389] In some implementations, the second information may include eleventh information and the twelfth information. Here, the eleventh information may be used to indicate whether the UE would transmit (or, is to transmit or requests to transmit) the fourth information. Or, the eleventh information may be used to indicate whether the UE would transmit (or, is to transmit or requests to transmit) the fourth information and the twelfth information. Or, the eleventh information may be used to indicate that the UE is to transmit or requests to transmit the fourth information and the twelfth information. The twelfth information may be used to indicate information related to the fourth information configuration. For example, the twelfth information may adopt the indication method of the second information in other embodiments of the disclosure. In an example, the number of bits of the twelfth information is 2, the twelfth information of "00" may correspond to the fourth information configuration of index 0, and the twelfth information "01" may correspond to the fourth information configuration of index 1. The twelfth information "10" may correspond to the fourth information configuration of index 2, and the twelfth information "11" may correspond to the fourth information configuration of index 3. In some implementations, the twelfth information may be included in CSI part 1. For example, Q bits may be newly added in CSI part 1 to indicate the twelfth information. Here, Q may be a positive integer. Q may be specified by protocols, or configured by higher layer signaling. Q may also be determined according to the number or type M of the fourth information configurations. For example, Q= , where the operator represents ceiling operation. The fourth information may be included in CSI part 2. In this way, the transmission method of the second information can be simplified. The situation that multiple second information overlaps with other PUCCH or PUSCH is avoided, and the implementation complexity of the UE can be reduced.

[0390] In some implementations, one sixth information may include configuration information of the twelfth information and the fourth information and / or configuration information of the eleventh information. For example, the sixth information may further include at least one of the following:

[0391] - A fourth PUCCH resource, e.g., a fourth PUCCH resource index. For example, the fourth PUCCH resource index may be the parameter PUCCH-ResourceId. The fourth PUCCH resource may be a PUCCH resource carrying the eleventh information.

[0392] - A sixth BWP index. The sixth BWP index may be the index of a BWP where the fourth PUCCH resource is located (or corresponding to the fourth PUCCH resource).

[0393] - A fifth PUCCH resource, e.g., a fifth PUCCH resource index. For example, the fifth PUCCH resource index may be the parameter PUCCH-ResourceId. The fifth PUCCH resource may be a PUCCH resource carrying the twelfth information and the fourth information.

[0394] - A seventh BWP index. The seventh BWP index may be the index of a BWP where the fifth PUCCH resource is located (or corresponding to the fifth PUCCH resource).

[0395] - A first PUSCH resource. The PUSCH resource may be a PUSCH resource carrying the twelfth information and the fourth information. The PUSCH resource may be a CG PUSCH resource. For example, a CG PUSCH configuration index parameter, such as the parameter ConfiguredGrantConfigIndex, may be configured.

[0396] - A first serving cell index. The first serving cell index is the index of a serving cell where the first PUSCH is transmitted.

[0397] - An eighth BWP index. The eighth BWP index is the index of a BWP where the first PUSCH resource is located (or, corresponding to the first PUSCH resource). Or, the eighth BWP index is the index of a BWP on a serving cell where the first PUSCH resource is located (or, corresponding to the first PUSCH resource).

[0398] - SR information corresponding to the eleventh information, for example, the index of an SR (e.g., parameter schedulingRequestID).

[0399] - SR resource information corresponding to the eleventh information, for example, the index of an SR resource (e.g., parameter schedulingRequestResourceId).

[0400] - The number of PRBs of the fifth PUCCH resource, for example, indicating the number of PRBs occupied by a PUCCH format (e.g., PUCCH format 2, or PUCCH format 3) carrying the twelfth information and the fourth information.

[0401] Note that the method for the first PUCCH resource in the embodiments of the disclosure may also be used for the fourth PUCCH resource, and the method for the second PUCCH resource may also be used for the fifth PUCCH resource. For example, in the embodiments of the disclosure, the first PUCCH may be replaced with the fourth PUCCH and the second PUCCH may be replaced with the fifth PUCCH.

[0402] In some implementations, if the UE is configured with a parameter regarding the number of PRBs of the fifth PUCCH resource, the number of PRBs of the transmitted PUCCH format carrying the twelfth information and the fourth information by the UE is determined according to the parameter. In this way, the number of times of blind detection of PRBs by the base station can be reduced, and thus the implementation complexity of the base station can be reduced, and the power consumption of the base station can be saved.

[0403] While the above describes the method of associating the indication of the second information with the fourth information configuration using a single bit or two bits of the second information, the example embodiments of the disclosure are equally applicable to second information with more than two bits. Accordingly, with the second information of more than two bits, the second information may be associated with a greater number, e.g. more than four, of fourth information configurations. The above described correspondence or mapping of the indication of the second information and the fourth information configuration is only an example and the indication of the second information and the fourth information configuration may be associated in any suitable way. For example, although it is described that the second information of a smaller value corresponds to the fourth information configuration of a smaller index, in some implementations, the second information of a larger value may correspond to the fourth information configuration of a smaller index.

[0404] In some implementations, the UE transmits the second information and the UE transmits the fourth information. For example, the fourth information may be fourth information corresponding to the second information (or fourth information corresponding to the fourth information configuration). In some implementations, the second information and the fourth information may be carried by a same physical channel (e.g., PUCCH or PUSCH), which can reduce delay and save UE power consumption. In some implementations, the second information and the fourth information may be carried by different physical channels (e.g., PUCCH or PUSCH), e.g., the UE may transmit the fourth information after transmitting the second information. In this way, when the base station does not receive the second information, the base station can reallocate the physical resources pre-allocated to the fourth information, so that the frequency spectrum utilization can be increased. The physical channel (e.g., PUCCH) carrying the second information satisfies a first predefined timing relationship with the physical channel (e.g., PUCCH or PUSCH) carrying the fourth information, the first predefined timing relationship may be that the time interval between the physical channel (e.g., PUCCH) carrying the second information and the physical channel carrying the fourth information is not less than or is greater than (or is greater than or equal to) or equal to a first predefined time. The first predefined time may be specified by protocols, or configured by a higher layer parameter. For example, the UE transmits an earliest PUCCH or PUSCH carrying the fourth information after transmitting the second information, where the time interval between the PUCCH or PUSCH and the physical channel carrying the second information is not less than or is greater than (or is greater than or equal to) the first predefined time. For another example, the UE transmits the PUCCH or PUSCH carrying the fourth information (e.g., an earliest PUCCH or PUSCH carrying the fourth information) after the first predefined time after transmitting the second information. For another example, the UE transmits the PUCCH carrying the fourth information in the earliest slot (e.g., PUCCH slot) after the first predefined time after transmitting the second information. For another example, the UE transmits the PUSCH carrying the fourth information in the earliest slot (e.g., PUSCH slot) after the first predefined time after transmitting the second information. Note that the PUCCH or the PUSCH carrying the fourth information may be the PUCCH resource (e.g., the second PUCCH resource) or the PUSCH resource (e.g., the PUSCH resource configured for the sixth information) described in other embodiments of the disclosure for transmission of the fourth information, or for example, may be the PUCCH resource or the PUSCH resource configured by higher layer signaling for transmission of the fourth information. The default value of the first predefined time may be 0, i.e., the value of the first predefined time is 0 if the UE is not configured with the first predefined time.

[0405] It is noted that the time unit of the first predefined time may be a symbol or a slot. The symbol or slot may be a symbol or slot with referenced to the SCS of the primary serving cell. The symbol or slot may also be a symbol or slot with referenced to the SCS of a serving cell where the PUSCH carrying the fourth information is located. For example, a parameter indicating the first predefined time may be configured for one or more fourth information, which can save higher layer signaling overhead. For another example, the first predefined time may be indicated with a parameter for each fourth information; for example, the UE may be configured with a list of parameters, one of the parameters corresponding to one fourth information. This method can improve the flexibility. Note that "fourth information" may be replaced with "fourth information configuration" or "second information" or "second information configuration" or 밶 pair or set of second information and fourth information".

[0406] Note that the PUCCH or PUSCH carrying the fourth information may be a PUCCH or PUSCH satisfying the first predefined condition. The earliest PUCCH or PUSCH carrying the fourth information may be an earliest PUCCH or PUSCH satisfying the first predefined condition. The first predefined condition may be at least one of the following:

[0407] - the PUCCH or PUSCH does not overlap with the first predefined symbol. For example, the earliest PUCCH or PUSCH satisfying the first predefined condition may be an earliest PUCCH or PUSCH without overlapping with the first predefined symbol. This method can avoid collisions and improve the transmission reliability.

[0408] The first predefined symbol may be specified by protocols and / or configured by higher layer signaling. For example, the first predefined symbol may be at least one of the following.

[0409] - Semi-statically configured (higher layer signaling configured) downlink symbols (e.g., downlink symbols configured by 3GPP parameters tdd-UL-DL-ConfigurationCommon or tdd-UL-DL-ConfigurationDedicated) and / or flexible symbols.

[0410] - A symbol of an SSB.

[0411] - A symbol of CORESET0 (a CORESET associated with a TypeO-PDCCH CSS set).

[0412] - Unavailable symbols configured by higher layer signaling.

[0413] - Y symbols after an SSB. Here, Y is an integer, which may be defined by protocols and / or configured by higher layer signaling.

[0414] - Inactive symbols of cell DRX (discontinuous reception).

[0415] - Downlink symbols and / or flexible symbols indicated by DCI format 2_0.

[0416] - Symbols of a downlink physical channel or signal on a same serving cell (e.g., symbols occupied by physical channels or signals), for example, symbols of a downlink physical channel or signal indicated by a DCI format, and for another example, symbols of a downlink physical channel or signal configured by higher layer signaling.

[0417] - Symbols of an uplink physical channel or signal on a same serving cell, for example, symbols of an uplink physical channel or signal indicated by a DCI format, and for another example, symbols of uplink physical channels or signals configured by higher layer signaling. For example, symbols of another PUSCH transmission indicated by a DCI format on a same serving cell.

[0418] In some implementations, a second transmission opportunity of a physical channel carrying the second information may be associated with a number A of fourth transmission opportunities of a physical channel carrying the fourth information. For example, the number A may be 1. As another example, the number A may be an integer greater than 1. If the fourth transmission opportunities associated with the second transmission opportunity (e.g., all the fourth transmission opportunities associated with the second transmission opportunity) cannot be transmitted (or overlap with the first predefined symbol), the UE does not transmit the second information in the second transmission opportunity. And / or, if the fourth transmission opportunities associated with the second transmission opportunity (e.g., at least one fourth transmission opportunity associated with the second transmission opportunity) does not overlap with the first predefined symbol, the UE may transmit the second information in the second transmission opportunity. This method can reduce the transmit power of the UE.

[0419] In some implementations, the fourth transmission opportunities associated with the second transmission opportunity may be at least one of the following:

[0420] - A fourth transmission opportunity satisfying that the interval from the second transmission opportunity to the fourth transmission opportunity is the first predefined time. Here, the fourth transmission opportunity is later than the second transmission opportunity.

[0421] - The earliest A fourth transmission opportunities (the number A of earliest fourth transmission opportunities) satisfying that the interval from the second transmission opportunity to the fourth transmission opportunity is no less than the first predefined time. Here, the fourth transmission opportunity is later than the second transmission opportunity.

[0422] In some implementations, at least one of the following may be specified by protocols and / or configured by higher layer signaling

[0423] - The UE does not expect that the PUCCH or PUSCH carrying the fourth information overlaps with the downlink physical channel or signal indicated by a DCI format on a same serving cell. This method can reduce the transmission delay of the fourth information.

[0424] - The UE does not expect that the PUCCH or PUSCH carrying the fourth information overlaps with the uplink physical channel or signal indicated by a DCI format on a same serving cell. This method can reduce the transmission delay of the fourth information.

[0425] - The UE does not expect that the PUSCH carrying the fourth information overlaps with another PUSCH indicated by a DCI format on a same serving cell. This method can reduce the transmission delay of the fourth information.

[0426] Note that in the above implementations, the UE may measure on the second RS after transmitting the second information, and then the UE transmits the fourth information. This method can save signaling overhead of the RS, thereby improving spectrum utilization. The physical channel (e.g., PUCCH) carrying the second information satisfies a second predefined timing relationship with the second RS, where the second predefined timing relationship may be that the time interval between the physical channel (e.g., PUCCH) carrying the second information and the second RS is not less than or is greater than (or is greater than or equal to) a second predefined time. The second predefined time may be specified by protocols, or configured by a higher layer parameter. For example, the UE measures on an earliest second RS after transmitting the second information, where the time interval between the second RS and the physical channel carrying the second information is not less than or is greater than (or is greater than or equal to) the second predefined time. In some implementations, the UE may be configured by higher layer signaling to measure on the second RS after transmitting the second information. The UE may also report a UE capability to support measurement on the second RS after transmitting the second information through a UE capability report. Here, measuring on the second RS after transmitting the second information may refer to measuring on the second RS before transmitting the fourth information. Note that "second RS" may be replaced with "RS" or "first and / or second RS". In this way, the flexibility of scheduling can be improved.

[0427] In some implementations, if the fourth information determined by the UE in a sixth time is not the same as the fourth information determined in a seventh time, the UE does not transmit the fourth information. And / or, if the fourth information determined in the sixth time is the same as the fourth information determined in the seventh time, the UE transmits the fourth information. Here, the sixth time and the seventh time satisfy a third condition. For example, the third condition may include at least one of the following:

[0428] - The sixth time may be earlier than the seventh time;

[0429] - The sixth time may be earlier than the physical channel carrying the second information;

[0430] - The seventh time may be later than the physical channel carrying the second information.

[0431] - The seventh time may be earlier than the physical channel carrying the fourth information;

[0432] - The sixth time may also be a time of an event trigger corresponding to the second information.

[0433] - The seventh time may be later than the time of the event trigger corresponding to the second information.

[0434] - The seventh time may be a time of an event trigger corresponding to another second information.

[0435] Note that the physical channel carrying the fourth information may be a physical channel carrying the fourth information associated with the physical channel carrying the second information. The "physical channel carrying the fourth information" may be replaced with the "transmission opportunity of the physical channel carrying the fourth information" and the "physical channel carrying the second information" may be replaced with the "transmission opportunity of the physical channel carrying the second information". This method can save the transmit power of the UE.

[0436] Note that the UE may indicate a capability to support the above method through a separate UE capability report.

[0437] In one example, if the fourth information determined by the UE after transmitting the second information is not the same as the fourth information determined before transmitting the second information, the UE does not transmit the fourth information. And / or, if the fourth information determined by the UE after transmitting the second information is the same as the fourth information determined before transmitting the second information, the UE transmits the fourth information. This method can save the transmit power of the UE.

[0438] Note that, in the embodiments of the disclosure, transmitting the second information may be understood as transmitting a physical channel or signal carrying the second information. The second information may be replaced with fourth information or other information.

[0439] In some implementations, at least one of the first information, the third information, the fifth information, the sixth information, or the ninth information may be configured in a physical cell group configuration parameter (e.g., parameter PhysicalCellGroupConfig) or a MAC cell group configuration parameter (e.g., parameter MAC-CellGroupConfig), which can save signaling overhead.

[0440] Note that the "serving cell" in the embodiments of the disclosure may be replaced with "BWP on serving cell" or "BWP".

[0441] Note that in the embodiment of the disclosure, the "second information" may be replaced with "positive second information". The "tenth information" may be replaced with "positive tenth information".

[0442] Note that in the embodiments of the disclosure, a PUCCH resource or PUSCH resource may also be configured with periodicity and / or offset. The number of offsets may be one or more. If a PUCCH resource or PUSCH resource is not configured with periodicity, the periodicity of the PUCCH resource or PUSCH resource may be considered to be 1 slot. For example, the periodicity of the second PUCCH resource or PUSCH resource may be N symbols, where N may be 2 or 6 or 7. The periodicity of less than one slot can reduce uplink transmission delay compared to the periodicity of M slots.

[0443] Note that the second information or the fourth information in the embodiments of the disclosure may also be used to indicate other UCI information and / or uplink data.
