Description

METHOD AND APPARATUS FOR RESOURCE MANAGEMENT FOR UE-INITIATED REPORTING IN WIRELESS COMMUNICATION SYSTEM

[0001] The present disclosure relates generally to wireless communication systems and, more specifically, the present disclosure relates to methods and apparatuses for resource management for user equipment (UE)-initiated reporting.

[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 (THz) 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.

[0008] The present disclosure provides method and apparatus for reporting of beam-related information in a wireless communication system.

[0009] According to an aspect of an exemplary embodiment, there is provided method and apparatus for reporting of beam-related information in a wireless communication system.

The descriptions of FIGURES 1-3 are not meant to imply physical or architectural limitations to how different embodiments may be implemented. Different embodiments of the present disclosure may be implemented in any suitably arranged communications system.

[0036] FIGURE 1 illustrates an example wireless network 100 according to embodiments of the present disclosure. The embodiment of the wireless network 100 shown in FIGURE 1 is for illustration only. Other embodiments of the wireless network 100 could be used without departing from the scope of this disclosure.

[0037] As shown in FIGURE 1, the wireless network 100 includes a gNB 101 (e.g., base station, BS), a gNB 102, and a gNB 103. The gNB 101 communicates with the gNB 102 and the gNB 103. The gNB 101 also communicates with at least one network 130, such as the Internet, a proprietary Internet Protocol (IP) network, or other data network.

[0038] The gNB 102 provides wireless broadband access to the network 130 for a first plurality of user equipments (UEs) within a coverage area 120 of the gNB 102. The first plurality of UEs includes a UE 111, which may be located in a small business; a UE 112, which may be located in an enterprise; a UE 113, which may be a WiFi hotspot; a UE 114, which may be located in a first residence; a UE 115, which may be located in a second residence; and a UE 116, which may be a mobile device, such as a cell phone, a wireless laptop, a wireless PDA, or the like. The gNB 103 provides wireless broadband access to the network 130 for a second plurality of UEs within a coverage area 125 of the gNB 103. The second plurality of UEs includes the UE 115 and the UE 116. In some embodiments, one or more of the gNBs 101-103 may communicate with each other and with the UEs 111-116 using 5G / NR, long term evolution (LTE), long term evolution-advanced (LTE-A), WiMAX, WiFi, or other wireless communication techniques.

[0039] Depending on the network type, the term “base station” or “BS” can refer to any component (or collection of components) configured to provide wireless access to a network, such as transmit point (TP), transmit-receive point (TRP), an enhanced base station (eNodeB or eNB), a 5G / NR base station (gNB), a macrocell, a femtocell, a WiFi access point (AP), or other wirelessly enabled devices. Base stations may provide wireless access in accordance with one or more wireless communication protocols, e.g., 5G / NR 3rdgeneration partnership project (3GPP) NR, long term evolution (LTE), LTE advanced (LTE-A), high speed packet access (HSPA), Wi-Fi 802.11a / b / g / n / ac, etc. For the sake of convenience, the terms “BS” and “TRP” are used interchangeably in this patent document to refer to network infrastructure components that provide wireless access to remote terminals. Also, depending on the network type, the term “user equipment” or “UE” can refer to any component such as “mobile station,” “subscriber station,” “remote terminal,” “wireless terminal,” “receive point,” or “user device.” For the sake of convenience, the terms “user equipment” and “UE” are used in this patent document to refer to remote wireless equipment that wirelessly accesses a BS, whether the UE is a mobile device (such as a mobile telephone or smartphone) or is normally considered a stationary device (such as a desktop computer or vending machine).

[0040] The dotted lines show the approximate extents of the coverage areas 120 and 125, which are shown as approximately circular for the purposes of illustration and explanation only. It should be clearly understood that the coverage areas associated with gNBs, such as the coverage areas 120 and 125, may have other shapes, including irregular shapes, depending upon the configuration of the gNBs and variations in the radio environment associated with natural and man-made obstructions.

[0041] As described in more detail below, one or more of the UEs 111-116 include circuitry, programing, or a combination thereof for resource management for UE-initiated reporting. In certain embodiments, one or more of the BSs 101-103 include circuitry, programing, or a combination thereof to support resource management for UE-initiated reporting.

[0042] Although FIGURE 1 illustrates one example of a wireless network, various changes may be made to FIGURE 1. For example, the wireless network 100 could include any number of gNBs and any number of UEs in any suitable arrangement. Also, the gNB 101 could communicate directly with any number of UEs and provide those UEs with wireless broadband access to the network 130. Similarly, each gNB 102-103 could communicate directly with the network 130 and provide UEs with direct wireless broadband access to the network 130. Further, the gNBs 101, 102, and / or 103 could provide access to other or additional external networks, such as external telephone networks or other types of data networks.

[0043] FIGURE 2 illustrates an example gNB 102 according to embodiments of the present disclosure. The embodiment of the gNB 102 illustrated in FIGURE 2 is for illustration only, and the gNBs 101 and 103 of FIGURE 1 could have the same or similar configuration. However, gNBs come in a wide variety of configurations, and FIGURE 2 does not limit the scope of this disclosure to any particular implementation of a gNB.

[0044] As shown in FIGURE 2, the gNB 102 includes multiple antennas 205a-205n, multiple transceivers 210a-210n, a controller / processor 225, a memory 230, and a backhaul or network interface 235.

[0045] The transceivers 210a-210n receive, from the antennas 205a-205n, incoming radio frequency (RF) signals, such as signals transmitted by UEs in the wireless network 100. The transceivers 210a-210n down-convert the incoming RF signals to generate IF or baseband signals. The IF or baseband signals are processed by receive (RX) processing circuitry in the transceivers 210a-210n and / or controller / processor 225, which generates processed baseband signals by filtering, decoding, and / or digitizing the baseband or IF signals. The controller / processor 225 may further process the baseband signals.

[0046] Transmit (TX) processing circuitry in the transceivers 210a-210n and / or controller / processor 225 receives analog or digital data (such as voice data, web data, e-mail, or interactive video game data) from the controller / processor 225. The TX processing circuitry encodes, multiplexes, and / or digitizes the outgoing baseband data to generate processed baseband or IF signals. The transceivers 210a-210n up-converts the baseband or IF signals to RF signals that are transmitted via the antennas 205a-205n.

[0047] The controller / processor 225 can include one or more processors or other processing devices that control the overall operation of the gNB 102. For example, the controller / processor 225 could control the reception of uplink (UL) channel signals and the transmission of downlink (DL) channel signals by the transceivers 210a-210n in accordance with well-known principles. The controller / processor 225 could support additional functions as well, such as more advanced wireless communication functions. For instance, the controller / processor 225 could support beam forming or directional routing operations in which outgoing / incoming signals from / to multiple antennas 205a-205n are weighted differently to effectively steer the outgoing signals in a desired direction. Any of a wide variety of other functions could be supported in the gNB 102 by the controller / processor 225.

[0048] The controller / processor 225 is also capable of executing programs and other processes resident in the memory 230, such as supporting resource management for UE-initiated reporting. The controller / processor 225 can move data into or out of the memory 230 as required by an executing process.

[0049] The controller / processor 225 is also coupled to the backhaul or network interface 235. The backhaul or network interface 235 allows the gNB 102 to communicate with other devices or systems over a backhaul connection or over a network. The interface 235 could support communications over any suitable wired or wireless connection(s). For example, when the gNB 102 is implemented as part of a cellular communication system (such as one supporting 5G / NR, LTE, or LTE-A), the interface 235 could allow the gNB 102 to communicate with other gNBs over a wired or wireless backhaul connection. When the gNB 102 is implemented as an access point, the interface 235 could allow the gNB 102 to communicate over a wired or wireless local area network or over a wired or wireless connection to a larger network (such as the Internet). The interface 235 includes any suitable structure supporting communications over a wired or wireless connection, such as an Ethernet or transceiver.

[0050] The memory 230 is coupled to the controller / processor 225. Part of the memory 230 could include a RAM, and another part of the memory 230 could include a Flash memory or other ROM.

[0051] Although FIGURE 2 illustrates one example of gNB 102, various changes may be made to FIGURE 2. For example, the gNB 102 could include any number of each component shown in FIGURE 2. Also, various components in FIGURE 2 could be combined, further subdivided, or omitted and additional components could be added according to particular needs.

[0052] FIGURE 3 illustrates an example UE 116 according to embodiments of the present disclosure. The embodiment of the UE 116 illustrated in FIGURE 3 is for illustration only, and the UEs 111-115 of FIGURE 1 could have the same or similar configuration. However, UEs come in a wide variety of configurations, and FIGURE 3 does not limit the scope of this disclosure to any particular implementation of a UE.

[0053] As shown in FIGURE 3, the UE 116 includes antenna(s) 305, a transceiver(s) 310, and a microphone 320. The UE 116 also includes a speaker 330, a processor 340, an input / output (I / O) interface (IF) 345, an input 350, a display 355, and a memory 360. The memory 360 includes an operating system (OS) 361 and one or more applications 362.

[0054] The transceiver(s) 310 receives from the antenna(s) 305, an incoming RF signal transmitted by a gNB of the wireless network 100. The transceiver(s) 310 down-converts the incoming RF signal to generate an intermediate frequency (IF) or baseband signal. The IF or baseband signal is processed by RX processing circuitry in the transceiver(s) 310 and / or processor 340, which generates a processed baseband signal by filtering, decoding, and / or digitizing the baseband or IF signal. The RX processing circuitry sends the processed baseband signal to the speaker 330 (such as for voice data) or is processed by the processor 340 (such as for web browsing data).

[0055] TX processing circuitry in the transceiver(s) 310 and / or processor 340 receives analog or digital voice data from the microphone 320 or other outgoing baseband data (such as web data, e-mail, or interactive video game data) from the processor 340. The TX processing circuitry encodes, multiplexes, and / or digitizes the outgoing baseband data to generate a processed baseband or IF signal. The transceiver(s) 310 up-converts the baseband or IF signal to an RF signal that is transmitted via the antenna(s) 305.

[0056] The processor 340 can include one or more processors or other processing devices and execute the OS 361 stored in the memory 360 in order to control the overall operation of the UE 116. For example, the processor 340 could control the reception of DL channel signals and the transmission of UL channel signals by the transceiver(s) 310 in accordance with well-known principles. In some embodiments, the processor 340 includes at least one microprocessor or microcontroller.

[0057] The processor 340 is also capable of executing other processes and programs resident in the memory 360. For example, the processor 340 may execute processes to utilize and / or identify resource management for UE-initiated reporting as described in embodiments of the present disclosure. The processor 340 can move data into or out of the memory 360 as required by an executing process. In some embodiments, the processor 340 is configured to execute the applications 362 based on the OS 361 or in response to signals received from gNBs or an operator. The processor 340 is also coupled to the I / O interface 345, which provides the UE 116 with the ability to connect to other devices, such as laptop computers and handheld computers. The I / O interface 345 is the communication path between these accessories and the processor 340.

[0058] The processor 340 is also coupled to the input 350, which includes, for example, a touchscreen, keypad, etc., and the display 355. The operator of the UE 116 can use the input 350 to enter data into the UE 116. The display 355 may be a liquid crystal display, light emitting diode display, or other display capable of rendering text and / or at least limited graphics, such as from web sites.

[0059] The memory 360 is coupled to the processor 340. Part of the memory 360 could include a random-access memory (RAM), and another part of the memory 360 could include a Flash memory or other read-only memory (ROM).

[0060] Although FIGURE 3 illustrates one example of UE 116, various changes may be made to FIGURE 3. For example, various components in FIGURE 3 could be combined, further subdivided, or omitted and additional components could be added according to particular needs. As a particular example, the processor 340 could be divided into multiple processors, such as one or more central processing units (CPUs) and one or more graphics processing units (GPUs). In another example, the transceiver(s) 310 may include any number of transceivers and signal processing chains and may be connected to any number of antennas. Also, while FIGURE 3 illustrates the UE 116 configured as a mobile telephone or smartphone, UEs could be configured to operate as other types of mobile or stationary devices.

[0061] FIGURE 4A and FIGURE 4B illustrate an example of wireless transmit and receive paths 400 and 450, respectively, according to embodiments of the present disclosure. For example, a transmit path 400 may be described as being implemented in a gNB (such as gNB 102), while a receive path 450 may be described as being implemented in a UE (such as UE 116). However, it will be understood that the receive path 450 can be implemented in a gNB and that the transmit path 400 can be implemented in a UE. In some embodiments, the transmit path 400 and / or receive path 450 is configured to support utilize resource management for UE-initiated reporting as described in embodiments of the present disclosure.

[0062] As illustrated in FIGURE 4A, the transmit path 400 includes a channel coding and modulation block 205, a serial-to-parallel (S-to-P) block 410, a size N Inverse Fast Fourier Transform (IFFT) block 415, a parallel-to-serial (P-to-S) block 420, an add cyclic prefix block 425, and an up-converter (UC) 430. The receive path 250 includes a down-converter (DC) 455, a remove cyclic prefix block 460, a S-to-P block 465, a size N Fast Fourier Transform (FFT) block 470, a parallel-to-serial (P-to-S) block 475, and a channel decoding and demodulation block 480.

[0063] In the transmit path 400, the channel coding and modulation block 405 receives a set of information bits, applies coding (such as a low-density parity check (LDPC) coding), and modulates the input bits (such as with Quadrature Phase Shift Keying (QPSK) or Quadrature Amplitude Modulation (QAM)) to generate a sequence of frequency-domain modulation symbols. The serial-to-parallel block 410 converts (such as de-multiplexes) the serial modulated symbols to parallel data in order to generate N parallel symbol streams, where N is the IFFT / FFT size used in the gNB 102 and the UE 116. The size N IFFT block 415 performs an IFFT operation on the N parallel symbol streams to generate time-domain output signals. The parallel-to-serial block 420 converts (such as multiplexes) the parallel time-domain output symbols from the size N IFFT block 415 in order to generate a serial time-domain signal. The add cyclic prefix block 425 inserts a cyclic prefix to the time-domain signal. The up-converter 430 modulates (such as up-converts) the output of the add cyclic prefix block 425 to a RF frequency for transmission via a wireless channel. The signal may also be filtered at a baseband before conversion to the RF frequency.

[0064] As illustrated in FIGURE 4B, the down-converter 455 down-converts the received signal to a baseband frequency, and the remove cyclic prefix block 460 removes the cyclic prefix to generate a serial time-domain baseband signal. The serial-to-parallel block 465 converts the time-domain baseband signal to parallel time-domain signals. The size N FFT block 470 performs an FFT algorithm to generate N parallel frequency-domain signals. The (P-to-S) block 475 converts the parallel frequency-domain signals to a sequence of modulated data symbols. The channel decoding and demodulation block 480 demodulates and decodes the modulated symbols to recover the original input data stream.

[0065] Each of the gNBs 101-103 may implement a transmit path 400 that is analogous to transmitting in the downlink to UEs 111-116 and may implement a receive path 450 that is analogous to receiving in the uplink from UEs 111-116. Similarly, each of UEs 111-116 may implement a transmit path 400 for transmitting in the uplink to gNBs 101-103 and may implement a receive path 450 for receiving in the downlink from gNBs 101-103.

[0066] Each of the components in FIGURES 4A and 4B can be implemented using only hardware or using a combination of hardware and software / firmware. As a particular example, at least some of the components in FIGURES 4A and 4B may be implemented in software, while other components may be implemented by configurable hardware or a mixture of software and configurable hardware. For instance, the FFT block 470 and the IFFT block 415 may be implemented as configurable software algorithms, where the value of size N may be modified according to the implementation.

[0067] Furthermore, although described as using FFT and IFFT, this is by way of illustration only and should not be construed to limit the scope of this disclosure. Other types of transforms, such as Discrete Fourier Transform (DFT) and Inverse Discrete Fourier Transform (IDFT) functions, can be used. It will be appreciated that the value of the variable N may be any integer number (such as 1, 2, 3, 4, or the like) for DFT and IDFT functions, while the value of the variable N may be any integer number that is a power of two (such as 1, 2, 4, 8, 16, or the like) for FFT and IFFT functions.

[0068] Although FIGURES 4A and 4B illustrate examples of wireless transmit and receive paths 400 and 450, respectively, various changes may be made to FIGURES 4A and 4B. For example, various components in FIGURES 4A and 4B can be combined, further subdivided, or omitted and additional components can be added according to particular needs. Also, FIGURES 4A and 4B are meant to illustrate examples of the types of transmit and receive paths that can be used in a wireless network. Any other suitable architectures can be used to support wireless communications in a wireless network.

[0069] As illustrated in FIGURE 5A, in a wireless system 500, a beam 501 for a device 504 can be characterized by a beam direction 502 and a beam width 503. For example, the device 504 (or UE 116) transmits RF energy in a beam direction and within a beam width. The device 504 receives RF energy in a beam direction and within a beam width. As illustrated in FIGURE 5A, a device at point A 505 can receive from and transmit to device 504 as Point A is within a beam width and direction of a beam from device 504. As illustrated in FIGURE 5A, a device at point B 506 cannot receive from and transmit to device 504 as Point B 506 is outside a beam width and direction of a beam from device 504. While FIGURE 5A, for illustrative purposes, shows a beam in 2-dimensions (2D), it should be apparent to those skilled in the art, that a beam can be in 3-dimensions (3D), where the beam direction and beam width are defined in space.

[0070] FIGURE 5B illustrates an example of a multi-beam operation 550 according to embodiments of the present disclosure. For example, the multi-beam operation 550 can be utilized by UE 116 of FIGURE 3. This example is for illustration only and other embodiments can be used without departing from the scope of the present disclosure.

[0071] In a wireless system, a device can transmit and / or receive on multiple beams. This is known as "multi-beam operation". While FIGURE 5B, for illustrative purposes, a beam is in 2D, it should be apparent to those skilled in the art, that a beam can be 3D, where a beam can be transmitted to or received from any direction in space.

[0072] FIGURE 6 illustrates an example of a transmitter structure 600 for beamforming according to embodiments of the present disclosure. In certain embodiments, one or more of gNB 102 or UE 116 includes the transmitter structure 600. For example, one or more of antenna 205 and its associated systems or antenna 305 and its associated systems can be included in transmitter structure 600. This example is for illustration only and other embodiments can be used without departing from the scope of the present disclosure.

[0073] Accordingly, embodiments of the present disclosure recognize that Rel-14 LTE and Rel-15 NR support up to 32 channel state information reference signal (CSI-RS) antenna ports which enable an eNB or a gNB to be equipped with a large number of antenna elements (such as 64 or 128). A plurality of antenna elements can then be mapped onto one CSI-RS port. For mmWave bands, although a number of antenna elements can be larger for a given form factor, a number of CSI-RS ports, that can correspond to the number of digitally precoded ports, can be limited due to hardware constraints (such as the feasibility to install a large number of analog-to-digital converters (ADCs) / digital-to-analog converters (DACs) at mmWave frequencies) as illustrated in FIGURE 6. Then, one CSI-RS port can be mapped onto a large number of antenna elements that can be controlled by a bank of analog phase shifters 601. One CSI-RS port can then correspond to one sub-array which produces a narrow analog beam through analog beamforming 605. This analog beam can be configured to sweep across a wider range of angles 620 by varying the phase shifter bank across symbols or slots / subframes. The number of sub-arrays (equal to the number of RF chains) is the same as the number of CSI-RS ports NCSI-PORT. A digital beamforming unit 610 performs a linear combination across NCSI-PORTanalog beams to further increase a precoding gain. While analog beams are wideband (hence not frequency-selective), digital precoding can be varied across frequency sub-bands or resource blocks. Receiver operation can be conceived analogously.

[0074] Since the transmitter structure 600 of FIGURE 6 utilizes multiple analog beams for transmission and reception (wherein one or a small number of analog beams are selected out of a large number, for instance, after a training duration that is occasionally or periodically performed), the term "multi-beam operation" is used to refer to the overall system aspect. This includes, for the purpose of illustration, indicating the assigned DL or UL TX beam (also termed "beam indication"), measuring at least one reference signal for calculating and performing beam reporting (also termed "beam measurement" and "beam reporting", respectively), and receiving a DL or UL transmission via a selection of a corresponding RX beam. The system of FIGURE 6 is also applicable to higher frequency bands such as >52.6GHz (also termed frequency range 4 or FR4). In this case, the system can employ only analog beams. Due to the O2 absorption loss around 60 GHz frequency (~10 dB additional loss per 100 m distance), a larger number and narrower analog beams (hence a larger number of radiators in the array) are needed to compensate for the additional path loss.

[0075] The text and figures are provided solely as examples to aid the reader in understanding the present disclosure. They are not intended and are not to be construed as limiting the scope of the present disclosure in any manner. Although certain embodiments and examples have been provided, it will be apparent to those skilled in the art based on the disclosures herein that changes in the embodiments and examples shown may be made without departing from the scope of the present disclosure. The transmitter structure 600 for beamforming is for illustration only and other embodiments can be used without departing from the scope of the present disclosure.

[0076] Although the figures illustrate different examples of user equipment, various changes may be made to the figures. For example, the user equipment can include any number of each component in any suitable arrangement. In general, the figures do not limit the scope of this disclosure to any particular configuration(s). Moreover, while figures illustrate operational environments in which various user equipment features disclosed in this patent document can be used, these features can be used in any other suitable system.

[0077] Any of the above variation embodiments can be utilized independently or in combination with at least one other variation embodiment.

[0078] Although the present disclosure has been described with exemplary embodiments, various changes and modifications may be suggested to one skilled in the art. It is intended that the present disclosure encompass such changes and modifications as fall within the scope of the appended claims. None of the descriptions in this application should be read as implying that any particular element, step, or function is an essential element that must be included in the claims scope. The scope of subject matter is defined by the claims.

[0079] In this disclosure, a beam is determined by either of;

[0080] - A transmission configuration indication (TCI) state, that establishes a quasi-colocation (QCL) relationship between a source reference signal (e.g. SSB and / or CSI-RS) and a target reference signal

[0081] - A spatial relation information that establishes an association to a source reference signal, such as SSB or CSI-RS or sounding reference signal (SRS).

[0082] In either case, the ID of the source reference signal identifies the beam.

[0083] The TCI state and / or the spatial relation reference RS can determine a spatial Rx filter for reception of downlink channels at the UE, or a spatial TX filter for transmission of uplink channels from the UE.

[0084] In (up to Rel.17) NR specification, the most resource-efficient reporting mechanism for a content (e.g. beam, CSI etc., or in general different report quantities) is aperiodic (in conjunction with aperiodic CSI-RS). On the other hand, with a well-chosen periodicity, periodic reporting (followed by semi-persistent) results in the lowest latency at the expense of resources. Although aperiodic reporting seems preferred from the overall operational perspective, in a few relevant scenarios the NW / gNB lacks knowledge on the DL channel condition - or, in other words, the UE (e.g., the UE 116) knows the DL channel condition better. Embodiments of the present disclosure recognize that, in this case, it is clearly beneficial if the UE can initiate its own aperiodic reporting for a content (e.g. beam, CSI etc.) or trigger a beam switching for a condition or event. For instance, when the UE is configured only with aperiodic beam reporting and the channel condition is worsened to the point of beam failure, the loss of link due to beam failure can be avoided if the UE can transmit an aperiodic beam report without having to wait for a beam report request / trigger from the NW / gNB or trigger a new beam update without having to wait for a beam change or update indication from the NW / gNB. Likewise, when the UE is configured only with aperiodic CSI reporting and the channel condition is worsened due to UE speed / movement, the performance degradation due to faster link quality degradation can be avoided if the UE can transmit an aperiodic CSI report without having to wait for a CSI request / trigger from the NW / gNB or trigger a new beam update without having to wait for a beam change or update indication from the NW / gNB. Such UE-initiated reporting and / or beam switching for a content can be enabled for other types of report quantities (different from common beam or CSI reports) and application scenarios.

[0085] Although UE-initiated reporting and / or beam switching and / or beam activation / deactivation can be beneficial, efficient designs are needed to ensure that the latency is reduced and, at the same time, error events can be minimized. Therefore, there is a need for efficient designs for UE-initiated reporting and / or beam switching and / or beam activation / deactivation for a content that can offer good trade-off between latency and reliability, in particular, when the UE-initiated beam management framework can include multiple report types (or report quantities), or / and multiple event types when a report types can be associated with an event (e.g. for beam report, the event can be beam failure, and for CSI, the event can be user throughput degradation or increasing retransmission rate). This disclosure provides example embodiments on the mentioned UE-initiated beam management framework herein including CSI / beam reporting, beam switching and beam activation / sub-selection. Furthermore, this disclosure also provides various design options for determining modulation and coding schemes (MCSs) for the L1 signaling mediums (including physical uplink control channel (PUCCH) and physical uplink shared channel (PUSCH)) that carries the UE-initiated report(s).

[0086] The present disclosure provides various detailed design examples on the UE-initiated beam management framework including UE-initiated / triggered beam / CSI reporting and / or UE-initiated / triggered beam switching and / or UE-initiated / triggered beam activation / deactivation / sub-selection. To better support / enable the UE-initiated and the event-based beam operations, this disclosure presents detailed methods of how to determine modulation and coding schemes (MCSs) for the L1 signaling mediums (including PUCCH and PUSCH) that carries the UE-initiated report(s).

[0087] In the present disclosure, a UE detects (or determines) a need for transmitting a UE-initiated / UE-triggered report (or initiation / triggering) of a (report-)type (A), (B), or (C), where

[0088] - (A) includes an initiator / trigger / pre-notification message

[0089] - (B) includes a report / content (comprising one or multiple report quantities)

[0090] - (C) includes both a trigger / pre-notification message and a (corresponding) report / content

[0091] The report is to facilitate / enable efficient / timely / fast / reliable communication over the link / channel between a target entity (e.g. NW / gNB or another device) and the UE, and the content (if reported) can include a quantity or quantities. At least one of the following examples can be used / configured for the content:

[0092] - In one example, the content includes beam-related quantity / quantities. For example, up to N≥1 indicators {Ii} or pairs of {(Ii,Ji)}, where Iiis an beam (source RS) indicator (e.g. CRI, synchronization signal block resource indicator (SSBRI)) and Jiis a beam metric (e.g. layer 1 reference signal received power (L1-RSRP), layer 1 signal-to-interference-plus-noise ratio (L1-SINR)).

[0093] - In one example, the content includes CSI-related quantity / quantities. For example, at least one of rank indicator (RI), precoding matrix indicator (PMI), channel quality indicator (CQI), CQI report interval (CRI), layer index (LI) is included.

[0094] - In one example, the content includes time-domain channel property (TDCP)-related quantity / quantities. For example, an indicator about the Doppler profile (e.g. Doppler spread or Doppler shift, relative Doppler spreads, or relative Doppler shifts), or an indicator about the auto-correlation profiles (e.g. (auto-)correlation values corresponding to a few dominant lags / delays).

[0095] - In one example, the content includes other (e.g. non-beam, non-CSI, non-TDCP) quantity / quantities.

[0096] - In one example, quantity / quantities comprises a selector / indicator indicating selection of one (or >1) of either

[0097] - beam (TCI state) TCI states (e.g. DL TCI state, UL TCI state, or unified (joint) DL / UL TCI state), or

[0098] - panel(s) (e.g. UE panels for DL reception or / and UL transmission), or

[0099] - antenna(e) (e.g. UE antennae for DL reception or / and UL transmission), or

[0100] - antenna port(s) (e.g. UE antenna ports for DL reception or / and UL transmission).

[0101] - In one example, quantity / quantities comprises an indicator indicating switching from one beam to another beam, or from one panel to another, or from one antenna port group to another antenna port group, or from N1SRS ports to N2SRS ports, where N1≠N2(e.g. this switching is for DL reception or / and UL transmission).

[0102] - In one example, the content includes beam-related quantity / quantities (examples herein) and at least one other quantity / quantities (examples herein).

[0103] - In one example, the content includes CSI-related quantity / quantities (examples herein) and at least one other quantity / quantities (examples herein).

[0104] - In one example, the content includes TDCP-related quantity / quantities (examples herein) and at least one other quantity / quantities (examples herein).

[0105] - In one example, the content includes beam-related quantity / quantities (examples herein) and CSI-related quantity / quantities (examples herein).

[0106] - In one example, the content includes beam-related quantity / quantities (examples herein) and TDCP-related quantity / quantities (examples herein).

[0107] - In one example, the content includes TDCP-related quantity / quantities (examples herein) and CSI-related quantity / quantities (examples herein).

[0108] In one example, the report is targeting a physical layer (L1) communication (e.g. L1 DL / UL, or L1 sidelink (SL)), i.e. such reporting is to enable fast / reliable DL / UL or SL transmission / reception.

[0109] In one example, the link / channel between the target entity and the UE is a Uu interface (i.e. DL, UL).

[0110] In one example, the link / channel between the target entity and the UE is a sidelink (SL), or a device-to-device (D2D) or PC5 interface.

[0111] In one example, such reporting can be non-event-based or autonomous, the UE can initiate / trigger the report autonomously (i.e. without being associated with any event) or unconditionally / freely. For example, the UE can be configured with a triggering time window (or multiple UL slots), and the UE can trigger the report during this window.

[0112] In one example, such reporting can be event-based, i.e., the UE can initiate / trigger the report only when it detects an event associated with the report, where the event can be of a (event-)type: type 0, type 1, and so on. In one example, type 0 corresponds to a beam-related event, type 1 corresponds to a CSI-related event, type 2 corresponds to a time-domain channel property (TDCP)-related event, and type 3 can be a non-CSI-related event (examples provided later). In one example, if a metric (depending on the event-type) is less than or equal to a threshold (or greater than or equal to a threshold), the event is detected or declared positive. The threshold is chosen such that a failure (e.g. beam / link failure) can be detected before it actually happens, and the UE-initiated report can avoid the failure.

[0113] In one example, such reporting can be non-event-based or event-based, based on report-type.

[0114] In one example, such reporting can be non-event-based or event-based, based on a configuration.

[0115] A few examples of the event-types and the report-types are provided in below Table 1 (for joint) and Table 2 / Table 3 (for separate). In these examples, the event-types and the report-types are separate (explicit). However, they can also be joint, as shown in below Table 4. A few examples of the autonomous UE-initiated report are shown in below Table 5.

[0116]

[0117]

[0118]

[0119]

[0120]

[0121] In one example, when there is no content associated with a pre-notification message / trigger, i.e., the report-type is (A), the trigger / pre-notification message simply provides a 'hint / alarm / cue' to the target entity according to at least one of the following examples.

[0122] - For example, the hint is about the communication link / channel. For example, it can imply a need for a new or updated report (e.g. beam or CSI or TDCP). In this case, it is up to NW whether to configure a report for the content (separately).

[0123] - For another example, the hint is about an RS transmission. For example, it can imply a need for an aperiodic or semi-persistent RS (e.g. CSI-RS, SRS) transmission. The RS transmission can be from the target entity, or from the UE.

[0124] - For another example, the hint is about a selection / switch. For example, it can imply a need for switching from current A to another A, where A is one of current panel(s), TRP(s) / RRH(s), resource sets, antenna groups, antenna port groups.

[0125] - For another example, the hint is about beam / CSI parameters. For example, the parameter can be codebook type (e.g. from Type I to Type II or vice versa), or rank restriction (e.g. from high rank to low rank or vice versa).

[0126] - For another example, the hint is about RS parameters. For example, the parameter can be related to a AP RS trigger, or RS periodicity, or number of SRS ports (panel switch, 1 panel to 2 panel or vice versa) or number of RS resources.

[0127] - For another example, the hint is about transmission scheme, which can be one of PMI-based, diversity (cyclic delay diversity (CDD), cycling, SFBC), reciprocity (NCB, or non-PMI-feedback), or based on partial CSI (e.g. CRI-i1 or CRI-i1-CQI or LI-CRI-i1 or LI-CRI-i1-CQI), or based on single TRP to multi-TRP switch (or vice versa).

[0128] - For another example, the hint is about transmission parameters, e.g. MCS, or number of CWs.

[0129] - For another example, when there is no pre-notification message / trigger associated with a content, i.e., the report-type is (B), the content can be transmitted using UL resource(s) configured (e.g. configured-grant PUSCH), or reserved for the UE-initiated report, or via a RACH procedure.

[0130] In one embodiment, a UE could send to the network (e.g., the network 130) one or more indicators / triggers each comprising / including / containing or corresponding to one or more of:

[0131] - An identity (ID) of the TCI state

[0132] - An index / ID of a higher layer RRC configured list / set / pool of TCI states that comprises / indicates / provides the TCI state

[0163] - When / if the UE does not receive from the network an ACK for the indicator(s) within the first time window / offset starting from the transmission of the indicator(s) or receives a NACK for the indicator(s) within the first time window / offset starting from the transmission of the indicator(s), the UE could (re-)send the indicator(s).

[0164] - When / if the UE receives from the network an ACK for the indicator(s) within the first time window / offset starting from the transmission of the indicator(s), the UE may perform the behaviors / operations and / or expect the corresponding network's operations according to the indicator(s) X duration / offset / time (e.g., X symbols / slots / etc.) starting from the reception of the ACK message for the indicator(s). The value of X could be: (i) fixed in the system specification(s), (ii) configured / provided / indicated by the network, e.g., via higher layer RRC signaling / parameter and / or MAC CE command and / or dynamic DCI based L1 signaling, or (iii) autonomously determined by the UE and sent to the network via uplink channels such as PUCCH / PUSCH.

[0165] The UE could be indicated / configured / provided by the network, e.g., via higher layer RRC signaling / parameter and / or MAC CE command and / or dynamic DCI based L1 signaling, the ACK (or NACK) for the indicator(s) specified herein in the present disclosure. For instance, The UE could be indicated / configured / provided by the network, e.g., via higher layer RRC signaling / parameter and / or MAC CE command and / or dynamic DCI based L1 signaling, a one-bit indicator to indicate ACK or NACK for the indicator(s) specified herein in the present disclosure for the UE-initiated beam operation; when / if the one-bit indicator is set to '1' (or '0'), the one-bit indicator could indicate an ACK for the indicator(s) sent by the UE for the UE-initiated beam operation; and when / if the one-bit indicator is not present / configured or is set to '0' (or '1'), the one-bit indicator could indicate a NACK for the indicator(s) sent by the UE (e.g., the UE 116) for the UE-initiated beam operation. Furthermore, when / if provided / indicated in a DCI, the ACK (or NACK) - e.g., the one-bit indicator as described herein - for the indicator(s) sent by the UE for the UE-initiated beam operation such as UE-initiated TCI state(s) / beam(s) switching / update / change could be indicated / provided via one or more new / dedicated DCI fields - e.g., denoted by 'ACK / NACK for UE-initiated beam switching' field(s) - in the DCI. Alternatively, when / if provided / indicated in a DCI, the ACK (or NACK) - e.g., the one-bit indicator as described herein - for the indicator(s) sent by the UE for the UE-initiated beam operation including UE-initiated TCI state(s) / beam(s) switching / update / change could be indicated / provided via / by repurposing one or more bits of one or more existing DCI fields in the DCI. For instance, the 'New Data Indicator' (NDI) field in a DCI could be repurposed / used to indicate the ACK (or NACK) for the indicator(s) sent by the UE for the UE-initiated beam operation; when / if the NDI field is toggled or is set to '1' (or '0'), the NDI could indicate an ACK for the indicator(s) sent by the UE for the UE-initiated beam operation including UE-initiated TCI state(s) / beam(s) switching / update / change; otherwise, the NDI could indicate a NACK for the indicator(s) sent by the UE for the UE-initiated beam operation including UE-initiated TCI state(s) / beam(s) switching / update / change.

[0166] A UE could determine modulation and / or coding scheme(s) for the signaling medium(s) - including PUCCH and PUSCH - that carries the indicator(s) / report(s) as specified herein in the present disclosure for the UE-initiated reporting according to one or more of:

[0167] - Type(s) of the indicator(s) / report(s): for example, the indicator(s) / report(s) could correspond to the trigger / pre-notification message in a (report-)type (A) based report or a (report-)type (C) based report according to those specified herein in the present disclosure; for another example, the indicator(s) / report(s) could contain, include or comprise one or more configurations / activations / indications of TCI state(s) and / or resource indicators such as SSBRIs / CRIs along with their associated beam metrics such as L1-RSRPs / L1-SINRs and / or etc. as specified herein in the present disclosure in part of the content(s) in a (report-)type (B) based report or a (report-)type (C) based report; for another example, the indicator(s) / report(s) for the UE-initiated reporting as specified herein in the present disclosure could correspond to a scheduling request (SR);

[0171] - Purpose(s) of the indicator(s) / report(s): e.g., when / if the indicator(s) / report(s) corresponds to the trigger / pre-notification message in a (report-)type (A) based report or a (report-)type (C) based report according to those specified herein in the present disclosure, the indicator(s) / report(s) could be used to trigger, initiate, indicate or request UL resource(s) for (i) CSI / beam reporting, wherein a beam report could include / contain / comprise one or more resource indicators including SSBRIs / CRIs and their associated beam metrics including L1-RSRPs / L1-SINRs, (ii) beam switching, wherein a beam switching report could include / contain / comprise one or more configurations / activations / indications of TCI states and / or etc.; furthermore, the indicator(s) / report(s) could be addressed to certain radio network temporary identifiers (RNTIs) such as cell RNTI (C-RNTI), etc.

[0172] - Network's indication(s) / configuration(s), e.g., via higher layer RRC signaling(s) / parameter(s) and / or MAC CE command(s) and / or dynamic DCI based L1 signaling(s), including e.g. uplink resource allocation(s) / assignment(s) for sending the indicator(s) / report(s) as specified herein in the present disclosure

[0173]

[0174] In one embodiment, the association / mapping between one or more of (1) type(s) of the indicator(s) / report(s), (2) signaling medium(s) of the indicator(s) / report(s), (3) format(s) of the signaling medium(s) that carries the indicator(s) / report(s), (4) payload size(s) of the indicator(s) / report(s), (5) purpose(s) of the indicator(s) / report(s) and (6) network's indication(s) / configuration(s), e.g., via higher layer RRC signaling(s) / parameter(s) and / or MAC CE command(s) and / or dynamic DCI based L1 signaling(s) as specified herein in the present disclosure for the UE-initiated reporting and various modulation and coding schemes (MCSs) used for the signaling medium(s) to that sends / carries the indicator(s) / report(s) for the UE-initiated reporting could be fixed (e.g., provided in look-up tables) in system specifications.

[0175] - For example, the UE could determine a MCS or a MCS index associating to a modulation order and a target code-rate in a MCS table specified for physical downlink shared channel (PDSCH) / PUSCH reception(s) / transmission(s) for the signaling medium(s) that sends / carries the indicator(s) / report(s) as specified herein in the present disclosure according to at least (1) type(s) of the indicator(s) / report(s) and (4) payload size(s) of the indicator(s) / report(s) as specified herein in the present disclosure for the UE-initiated reporting. In one example, the UE could determine, e.g., binary phase-shift keying (BPSK) (or QPSK) as the modulation scheme and / or Reed-Muller code (e.g., with a target code-rate / etc.) as the coding scheme according to the association / mapping rule(s) specified in system specifications for the indicator(s) / report(s), when / if the type(s) of the indicator(s) / report(s) corresponds to the trigger / pre-notification message in a (report-)type (A) based report or a (report-)type (C) based report according to those specified herein in the present disclosure and the payload size of the indicator(s) / report(s) - in terms of number of UCI bits - is less than a threshold (e.g., 2 bits). For this case, after the UE has determined the MCS for the indicator(s) / report(s), the UE could send to the network the indicator(s) / report(s) via the allocated / configured uplink resources including PUCCH and / or PUSCH using various formats / configurations including, e.g., format(s) 0, 1, 2, 3 and / or 4 for PUCCH and / or type-1 / 2 CG and / or DG for PUSCH transmission(s). In another example, the UE could determine, e.g., 64QAM as the modulation scheme and / or Polar code (e.g., with a target code-rate / etc.) as the coding scheme according to the association / mapping rule(s) specified in system specifications for the indicator(s) / report(s), when / if the type(s) of the indicator(s) / report(s) corresponds to both the trigger / pre-notification message in a (report-)type (A) based report or a (report-)type (C) based report and a beam / CSI report (including at least one or more resource indicators and their associated beam metrics) according to those specified herein in the present disclosure and the payload size of the indicator(s) / report(s) - in terms of number of UCI bits - is greater than a threshold (e.g., 11 bits). For this case, after the UE has determined the MCS for the indicator(s) / report(s), the UE could send the indicator(s) / report(s) via the allocated / configured uplink resources including PUCCH and / or PUSCH using various formats / configurations including, e.g., format(s) 0, 1, 2, 3 and / or 4 for PUCCH and / or type-1 / 2 CG and / or DG for PUSCH transmission(s). That is, for this design example, the determination of the MCS(s) for sending the indicator(s) / report(s) as specified herein in the present disclosure for the UE-initiated reporting is irrespective / regardless of the used / applied signaling medium(s) - e.g., PUCCH and / or PUSCH - and / or the corresponding signaling medium format(s) / configuration(s) - e.g., PUCCH format(s) 0 / 1 / 2 / 3 / 4 or CG / DG PUSCH(s). The UE could also send to the network information related to the determined MCS or MCS index, e.g., in part of the indicator(s) / report(s) - e.g., in part of the trigger / pre-notification message - for the UE-initiated reporting as specified herein in the present disclosure. One conceptual example of the association / mapping between the MCS(s) and (1) type(s) of the indicator(s) / report(s) and (4) payload size(s) of the indicator(s) / report(s) as specified herein in the present disclosure for the UE-initiated reporting is provided in above Table 6.

[0176] - For another example, the UE could determine a MCS or a MCS index associating to a modulation order and a target code-rate in a MCS table specified for PDSCH / PUSCH reception(s) / transmission(s) for the signaling medium(s) that sends / carries the indicator(s) / report(s) as specified herein in the present disclosure according to at least (1) type(s) of the indicator(s) / report(s), (2) signaling medium(s) of the indicator(s) / report(s), and (3) format(s) of the signaling medium(s) that carries the indicator(s) / report(s). In one example, the UE could determine, e.g., BPSK (or QPSK) as the modulation scheme and / or Reed-Muller code (with a target code-rate / etc.) as the coding scheme according to the association / mapping rule(s) specified in system specifications for the indicator(s) / report(s), when / if the type(s) of the indicator(s) / report(s) corresponds to the trigger / pre-notification message in a (report-)type (A) based report or a (report-)type (C) based report according to those specified herein in the present disclosure and the UE uses / applies PUCCH format 0 as the signaling medium to send the indicator(s) / report(s). For this case, the UE could determine the payload size of the indicator(s) / report(s) from the type(s) of the indicator(s) / report(s) - e.g., 1 or 2 bit(s) for the indicator(s) / report(s) corresponding to the trigger / pre-notification message as specified herein in the present disclosure, according to, e.g., (i) network's configuration(s) / indication(s), e.g., via higher layer RRC signaling(s) and / or MAC CE command(s) and / or dynamic DCI based L1 signaling(s), (ii) fixed rule(s) in system specification(s), and / or (iii) UE's autonomous determination, which could be further sent to the network via uplink report(s). In another example, the UE could determine, e.g., a MCS index in a MCS table specified for PDSCH / PUSCH reception(s) / transmission(s) comprising a modulation order and a target code-rate, according to the association / mapping rule(s) specified in system specification(s) for the indicator(s) / report(s), when the type(s) of indicator(s) / report(s) corresponds to both the trigger / pre-notification message in a (report-)type (A) based report or a (report-)type (C) based report and a CSI / beam report comprising at least one or more resource indicators / beam metrics according to those specified herein in the present disclosure and the UE uses / applies CG (type-1 or type-2) PUSCH(s) as the signaling medium to send the indicator(s) / report(s). The UE could also send to the network information related to the determined MCS or MCS index, e.g., in part of the indicator(s) / report(s) - e.g., in part of the trigger / pre-notification message - for the UE-initiated reporting as specified herein in the present disclosure. One conceptual example of the association / mapping between the MCS(s) and (1) type(s) of the indicator(s) / report(s), (2) signaling medium(s) of the indicator(s) / report(s), and (3) format(s) of the signaling medium(s) that carries the indicator(s) / report(s) as specified herein in the present disclosure for the UE-initiated reporting is provided in below Table 7.

[0178] - In one example, when / if the type(s) of the indicator(s) / report(s) corresponds to the trigger / pre-notification message in a (report-)type (A) based report or a (report-)type (C) based report according to those specified herein in the present disclosure, the UE could first determine the payload size of the indicator(s) / report(s) from the type(s) of the indicator(s) / report(s) - e.g., 1 or 2 bit(s) for the indicator(s) / report(s) corresponding to the trigger / pre-notification message as specified herein in the present disclosure, according to, e.g., (i) network's configuration(s) / indication(s), e.g., via higher layer RRC signaling(s) and / or MAC CE command(s) and / or dynamic DCI based L1 signaling(s), (ii) fixed rule(s) in system specification(s), and / or (iii) UE's autonomous determination, which could be further sent to the network via uplink report(s); the UE could then determine the signaling medium(s) - e.g., PUCCH and / or PUSCH - and / or format(s) of the signaling medium(s) that carries the indicator(s) / report(s) - e.g., PUCCH format(s) 0 / 1 / 2 / 3 / 4 and / or type-1 / 2 CG and / or DG PUSCH(s) corresponding to the indicator(s) / report(s) - e.g., PUCCH format 0 for the indicator(s) / report(s) corresponding to the trigger / pre-notification message as specified herein in the present disclosure, according to, e.g., (i) network's configuration(s) / indication(s), e.g., via higher layer RRC signaling(s) and / or MAC CE command(s) and / or dynamic DCI based L1 signaling(s), (ii) fixed rule(s) in system specification(s), and / or (iii) UE's autonomous determination, which could be further sent to the network via uplink report(s). Based on or according to the determined payload size of the indicator(s) / report(s) and / or the determined signaling medium(s) and the corresponding / associated format(s) for the determined signaling medium(s), the UE could determine a MCS or a MCS index associating to a modulation order and a target code-rate in a MCS table specified for PDSCH / PUSCH reception(s) / transmission(s) for the signaling medium(s) that sends / carries the indicator(s) / report(s) as specified herein in the present disclosure.

Part 1 and part 2 of the UE-initiated beam / CSI report(s) as specified herein in the present disclosure could be separately encoded and reported in a single reporting instance. The first part (or part 1) of the UE-initiated beam / CSI report could be of fixed payload size, which could provide or indicate information related to the second part (or part 2) of the UE-initiated beam / CSI report. Furthermore, part 1 of the UE-initiated beam / CSI report could be used to identify / indicate the size of the payload in part 2 of the UE-initiated beam / CSI report. Part 1 of the UE-initiated beam / CSI report shall be transmitted in its entirety before the transmission of part 2 of the UE-initiated beam / CSI report. In one example, part 2 of the UE-initiated beam / CSI report can be absent. When absent, the UE-initiated beam / CSI report is via part 1 only (i.e. one part UCI), and when present, the UE-initiated beam / CSI report is via both part 1 and part 2 (i.e. two-part UCI). In one example, part 2 of the UE-initiated beam / CSI report is present, but its payload could vary depending on the information in part 1. In the present disclosure, part 1 of the UE-initiated beam / CSI report could provide / indicate information related to the MCS(s) used for the signaling medium(s) that carries / sends (part 1 and / or part 2 of) the UE-initiated beam / CSI report(s) in part of the content(s) in a (report-)type (B) based report or a (report-)type (C) based report as specified herein in the present disclosure associated / corresponding to the trigger / pre-notification message.

For this case / design example, part 1 of the UE-initiated beam / CSI report(s) as specified herein in the present disclosure could provide / contain / include a one-bit indicator. When / if the one-bit indicator is set to '0' (or '1'), the first candidate MCS among the one or more provided / configured / indicated candidate MCSs and / or the candidate MCS corresponding to the first row of a (provided / configured / indicated) MCS table as specified herein in the present disclosure could be used / applied for the signaling medium(s) that carries / sends (part 1 and / or part 2) of the UE-initiated beam / CSI report(s) in part of the content(s) in a (report-)type (B) based report or a (report-)type (C) based report as specified herein in the present disclosure. When / if the one-bit indicator is set to '1' (or '0'), the second candidate MCS among the one or more provided / configured / indicated candidate MCSs and / or the candidate MCS corresponding to the second row of a (provided / configured / indicated) MCS table as specified herein in the present disclosure could be used / applied for the signaling medium(s) that carries / sends (part 1 and / or part 2 of) the UE-initiated beam / CSI report(s) in part of the content(s) in a (report-)type (B) based report or a (report-)type (C) based report as specified herein in the present disclosure.

For this case / design example, part 1 of the UE-initiated beam / CSI report(s) as specified herein in the present disclosure could provide / contain / include a one-bit indicator. When / if the one-bit indicator is set to '0' (or '1'), the first candidate MCS among the provided / configured / indicated candidate MCSs and / or the candidate MCS corresponding to the first row of a (provided / configured / indicated) MCS table as specified herein in the present disclosure could be used / applied for the signaling medium(s) that carries / sends (part 1 and / or part 2 of) the UE-initiated beam / CSI report(s) in part of the content(s) in a (report-)type (B) based report or a (report-)type (C) based report as specified herein in the present disclosure. When / if the one-bit indicator is set to '1' (or '0'), the second candidate MCS among the provided / configured / indicated candidate MCSs and / or the candidate MCS corresponding to the second row of a (provided / configured / indicated) MCS table as specified herein in the present disclosure could be used / applied for the signaling medium(s) that carries / sends (part 1 and / or part 2 of) the UE-initiated beam / CSI report(s) in part of the content(s) in a (report-)type (B) based report or a (report-)type (C) based report as specified herein in the present disclosure.

For this case / design example, part 1 of the UE-initiated beam / CSI report(s) as specified herein in the present disclosure could provide / contain / include a multi-bit indicator. For this case / design example, each of the state of the multi-bit indicator (e.g., 4 states for a 2-bit indicator and 16 states for a 4-bit indicator) could correspond / associated to a candidate MCS among the one or more provided / indicated / configured candidate MCSs and a candidate MCS corresponding to a row of a (provided / configured / indicated) MCS table as specified herein in the present disclosure. The correspondence / association could be based on, (1) fixed rule(s) in system specification(s), e.g., the states of the multi-bit indicator and the one or more provided / configured / indicated candidate MCSs / rows that correspond to the candidate MCSs in a (provided / configured / indicated) MCS table could be one-to-one mapped in an ascending / descending order of the candidate MCS index(es) and / or index(es) of the states of the multi-bit indicator, (2) network's configuration(s) / indication(s), e.g., via higher layer RRC signaling(s) / parameter(s) and / or MAC CE command(s) and / or dynamic DCI based L1 signaling(s), and / or (3) UE's autonomous selection / determination which could be further sent to the network, e.g., via / in part of the uplink report(s). For this case / design example, when / if the multi-bit indicator is set to a state (e.g., '00' for a 2-bit indicator), the candidate MCS among the provided / configured / indicated candidate MCSs that is associated to the state (e.g., the first candidate MCS) and / or the candidate MCS corresponding to the row of a (provided / configured / indicated) MCS table that is associated to the state (e.g., the first row) as specified herein in the present disclosure could be used / applied for the signaling medium(s) that carries / sends (part 1 and / or part 2 of) the UE-initiated beam / CSI report(s) in part of the content(s) in a (report-)type (B) based report or a (report-)type (C) based report as specified herein in the present disclosure.

[0210] - In another example, the UE could be provided / indicated / configured by the network, e.g., via higher layer RRC signaling(s) / parameter(s) and / or MAC CE command(s) and / or dynamic DCI based L1 signaling(s), up to K candidate MCSs and / or one or more MCS tables each comprising up to K rows with each row corresponding to a candidate MCS, wherein a candidate MCS could comprise at least a modulation order / scheme and a target code-rate for a corresponding channel coding scheme. For this case / design example, part 1 of the UE-initiated beam / CSI report(s) as specified herein in the present disclosure could provide / contain / include a k-bit indicator with . For this case / design example, each of the state of the k-bit indicator (e.g., 4 states for a 2-bit indicator and 16 states for a 4-bit indicator) could correspond / associated to a candidate MCS among the provided / indicated / configured (e.g., K) candidate MCSs and a candidate MCS corresponding to a row of a (provided / configured / indicated) MCS table as specified herein in the present disclosure. The correspondence / association could be based on, (1) fixed rule(s) in system specification(s), e.g., the states of the k-bit indicator and the provided / configured / indicated (e.g., K) candidate MCSs / (e.g., K) rows that correspond to the candidate MCSs in a (provided / configured / indicated) MCS table could be one-to-one mapped in an ascending / descending order of the candidate MCS index(es) and / or index(es) of the states of the k-bit indicator, (2) network's configuration(s) / indication(s), e.g., via higher layer RRC signaling(s) / parameter(s) and / or MAC CE command(s) and / or dynamic DCI based L1 signaling(s), and / or (3) UE's autonomous selection / determination which could be further sent to the network, e.g., via / in part of the uplink report(s). For this case / design example, when / if the k-bit indicator is set to a state (e.g., '00' for a 2-bit indicator), the candidate MCS among the provided / configured / indicated candidate MCSs that is associated to the state (e.g., the first candidate MCS) and / or the candidate MCS corresponding to the row of a (provided / configured / indicated) MCS table that is associated to the state (e.g., the first row) as specified herein in the present disclosure could be used / applied for the signaling medium(s) that carries / sends (part 1 and / or part 2 of) the UE-initiated beam / CSI report(s) in part of the content(s) in a (report-)type (B) based report or a (report-)type (C) based report as specified herein in the present disclosure.

[0211] Optionally, the UE could send to the network (e.g., the network 130) a trigger / pre-notification message in a (report-)type (A) based report or a (report-)type (C) based report as specified herein in the present disclosure to also indicate the MCS(s) used for the signaling medium(s) that carries / sends, e.g., part 1 of, the UE-initiated beam / CSI report(s) in part of the content(s) in a (report-)type (B) based report or a (report-)type (C) based report as specified herein in the present disclosure associated / corresponding to the trigger / pre-notification message according to those specified herein in the present disclosure, and / or the UE could send to the network a trigger / pre-notification message in a (report-)type (A) based report or a (report-)type (C) based report as specified herein in the present disclosure that also provides / indicates / includes / comprises / contains the information related to the MCS(s) used for the signaling medium(s) that carries / sends, e.g., part 1 of, the UE-initiated beam / CSI report(s) in part of the content(s) in a (report-)type (B) based report or a (report-)type (C) based report as specified herein in the present disclosure associated / corresponding to the trigger / pre-notification message.

[0212] In (up to Rel.17) NR specification, the most resource-efficient reporting mechanism for a content (e.g. beam, CSI etc., or in general different report quantities) is aperiodic (in conjunction with aperiodic CSI-RS). On the other hand, with a well-chosen periodicity, periodic reporting (followed by semi-persistent) results in the lowest latency at the expense of resources. Although aperiodic reporting seems preferred from the overall operational perspective, in a few relevant scenarios the NW / gNB lacks knowledge on the DL channel condition - or, in other words, the UE knows the DL channel condition better. In this case, it is clearly beneficial if the UE can initiate its own aperiodic reporting for a content (e.g. beam, CSI etc.) or trigger a beam switching for a condition or event. For instance, when the UE is configured only with aperiodic beam reporting and the channel condition is worsened to the point of beam failure, the loss of link due to beam failure can be avoided if the UE can transmit an aperiodic beam report without having to wait for a beam report request / trigger from the NW / gNB or trigger a new beam update without having to wait for a beam change or update indication from the NW / gNB. Likewise, when the UE is configured only with aperiodic CSI reporting and the channel condition is worsened due to UE speed / movement, the performance degradation due to faster link quality degradation can be avoided if the UE can transmit an aperiodic CSI report without having to wait for a CSI request / trigger from the NW / gNB or trigger a new beam update without having to wait for a beam change or update indication from the NW / gNB. Such UE-initiated reporting and / or beam switching for a content can be enabled for other types of report quantities (different from common beam or CSI reports) and application scenarios.

[0213] Although UE-initiated reporting and / or beam switching and / or beam activation / deactivation can be beneficial, efficient designs are needed to ensure that the latency is reduced and, at the same time, error events can be minimized. Therefore, there is a need for efficient designs for UE-initiated reporting and / or beam switching and / or beam activation / deactivation for a content that can offer good trade-off between latency and reliability, in particular, when the UE-initiated beam management framework can include multiple report types (or report quantities), or / and multiple event types when a report types can be associated with an event (e.g. for beam report, the event can be beam failure, and for CSI, the event can be user throughput degradation or increasing retransmission rate).

[0214] The present disclosure provides various detailed design examples on the UE-initiated beam management framework including UE-initiated / triggered beam / CSI reporting and / or UE-initiated / triggered beam switching and / or UE-initiated / triggered beam activation / deactivation / sub-selection. To better support / enable the UE-initiated and the event-based beam operations, this disclosure presents detailed methods of sending the UE-initiated report as a UCI over PUCCH and / or PUSCH.

[0215] In one example, when there is no content associated with a pre-notification message / trigger, i.e., the report-type is (A), the trigger / pre-notification message simply provides a 'hint / alarm / cue' to the target entity according to at least one of the following examples.

[0216] - For example, the hint is about the communication link / channel. For example, it can imply a need for a new or updated report (e.g. beam or CSI or TDCP). In this case, it is up to NW whether to configure a report for the content (separately).

[0217] - For another example, the hint is about an RS transmission. For example, it can imply a need for an aperiodic or semi-persistent RS (e.g. CSI-RS, SRS) transmission. The RS transmission can be from the target entity, or from the UE.

[0218] - For another example, the hint is about a selection / switch. For example, it can imply a need for switching from current A to another A, where A is one of current panel(s), TRP(s) / RRH(s), resource sets, antenna groups, antenna port groups.

[0219] - For another example, the hint is about beam / CSI parameters. For example, the parameter can be codebook type (e.g. from Type I to Type II or vice versa), or rank restriction (e.g. from high rank to low rank or vice versa).

[0220] - For another example, the hint is about RS parameters. For example, the parameter can be related to a AP RS trigger, or RS periodicity, or number of SRS ports (panel switch, 1 panel to 2 panel or vice versa) or number of RS resources.

[0221] - For another example, the hint is about transmission scheme, which can be one of PMI-based, diversity (CDD, cycling, SFBC), reciprocity (NCB, or non-PMI-feedback), or based on partial CSI (e.g. CRI-i1 or CRI-i1-CQI or LI-CRI-i1 or LI-CRI-i1-CQI), or based on single TRP to multi-TRP switch (or vice versa).

[0222] - For another example, the hint is about transmission parameters, e.g. MCS, or number of CWs.

[0223] - For another example, when there is no pre-notification message / trigger associated with a content, i.e., the report-type is (B), the content can be transmitted using UL resource(s) configured (e.g. configured-grant PUSCH), or reserved for the UE-initiated report, or via a RACH procedure.

[0224] In one embodiment, a UE could send to the network, in one or more UE-initiated report, one or more indicators / triggers (or contents as specified herein in the present disclosure corresponding to the trigger / pre-notification message) each comprising / including / containing or corresponding to one or more of:

[0254] - A bitmap with each bit position of the bitmap corresponding to a candidate TCI state / TCI state ID / TCI state index / RS index or ID / resource indicator / etc. according to those specified herein in the present disclosure; for this case, when / if a bit position of the bitmap is set to '1' (or '0'), the TCI state / TCI state ID / TCI state index / RS index or ID / resource indicator / etc. corresponding to the bit position could be for the UE-initiated beam(s) / TCI state(s) switching / update / change as specified herein in the present disclosure.

For instance, the UE could send to the network an indicator to trigger a TCI state change / update / switch for one or more channels or signals. Furthermore, throughout the present disclosure, a MCS can be replaced by a transport block size (TBS) and / or a MCS table can be replaced by a TBS table, and the corresponding operations / procedures equally apply.

[0256] The indicator(s) described herein in the present disclosure could correspond to the trigger / pre-notification message in a (report-)type (A) based report or a (report-)type (C) based report, or part of the (corresponding) content in a (report-)type (B) based report or a (report-)type (C) based report. Furthermore, the signaling medium / container for reporting the indicator(s) as specified herein in the present disclosure (or equivalently, the trigger / pre-notification message in a (report-)type (A) based report or a (report-)type (C) based report, or part of the (corresponding) content in a (report-)type (B) based report or a (report-)type (C) based report) could be PUCCH, PUSCH, PRACH, MAC CE, UCI and etc. The UE (e.g., the UE 116) may expect to receive from the network an ACK (or NACK) for the indicator(s) specified herein in the present disclosure within a first time window / offset (e.g., in terms of the number of slots / symbols / etc.) starting from the transmission of the indicator(s) (e.g., starting from the corresponding slot / symbol / etc.). The value of the first time window / offset could be: (i) fixed in the system specification(s), (ii) configured / provided / indicated by the network, e.g., via higher layer RRC signaling / parameter and / or MAC CE command and / or dynamic DCI based L1 signaling, or (iii) autonomously determined by the UE and sent to the network via uplink channels such as PUCCH / PUSCH.

[0257] - When / if the UE does not receive from the network an ACK for the indicator(s) within the first time window / offset starting from the transmission of the indicator(s) or receives a NACK for the indicator(s) within the first time window / offset starting from the transmission of the indicator(s), the UE could (re-)send the indicator(s).

[0258] - When / if the UE receives from the network an ACK for the indicator(s) within the first time window / offset starting from the transmission of the indicator(s), the UE may perform the behaviors / operations and / or expect the corresponding network's operations according to the indicator(s) X duration / offset / time (e.g., X symbols / slots / etc.) starting from the reception of the ACK message for the indicator(s). The value of X could be: (i) fixed in the system specification(s), (ii) configured / provided / indicated by the network, e.g., via higher layer RRC signaling / parameter and / or MAC CE command and / or dynamic DCI based L1 signaling, or (iii) autonomously determined by the UE and sent to the network (e.g., the network 130) via uplink channels such as PUCCH / PUSCH.

[0259] The UE could be indicated / configured / provided by the network, e.g., via higher layer RRC signaling / parameter and / or MAC CE command and / or dynamic DCI based L1 signaling, the ACK (or NACK) for the indicator(s) specified herein in the present disclosure. For instance, The UE could be indicated / configured / provided by the network, e.g., via higher layer RRC signaling / parameter and / or MAC CE command and / or dynamic DCI based L1 signaling, a one-bit indicator to indicate ACK or NACK for the indicator(s) specified herein in the present disclosure for the UE-initiated beam operation; when / if the one-bit indicator is set to '1' (or '0'), the one-bit indicator could indicate an ACK for the indicator(s) sent by the UE for the UE-initiated beam operation; and when / if the one-bit indicator is not present / configured or is set to '0' (or '1'), the one-bit indicator could indicate a NACK for the indicator(s) sent by the UE for the UE-initiated beam operation. Furthermore, when / if provided / indicated in a DCI, the ACK (or NACK) - e.g., the one-bit indicator as described herein - for the indicator(s) sent by the UE for the UE-initiated beam operation such as UE-initiated TCI state(s) / beam(s) switching / update / change could be indicated / provided via one or more new / dedicated DCI fields - e.g., denoted by 'ACK / NACK for UE-initiated beam switching' field(s) - in the DCI. Alternatively, when / if provided / indicated in a DCI, the ACK (or NACK) - e.g., the one-bit indicator as described herein - for the indicator(s) sent by the UE for the UE-initiated beam operation including UE-initiated TCI state(s) / beam(s) switching / update / change could be indicated / provided via / by repurposing one or more bits of one or more existing DCI fields in the DCI. For instance, the 'New Data Indicator' (NDI) field in a DCI could be repurposed / used to indicate the ACK (or NACK) for the indicator(s) sent by the UE for the UE-initiated beam operation; when / if the NDI field is toggled or is set to '1' (or '0'), the NDI could indicate an ACK for the indicator(s) sent by the UE for the UE-initiated beam operation including UE-initiated TCI state(s) / beam(s) switching / update / change; otherwise, the NDI could indicate a NACK for the indicator(s) sent by the UE for the UE-initiated beam operation including UE-initiated TCI state(s) / beam(s) switching / update / change.

[0260] Throughout the present disclosure, a UE-initiated (UEI) report could provide / contain / include / comprise one or more of the indicators / triggers as described herein in the present disclosure, which could correspond to the trigger / pre-notification message in a (report-)type (A) based report or a (report-)type (C) based report, or part of the (corresponding) content in a (report-)type (B) based report or a (report-)type (C) based report according to those specified herein in the present disclosure. For this case, uplink control information (UCI) types reported in a PUCCH could include the UEI report, and UCI bits could include UEI report bits.

[0261] A UE could be configured up to four sets of PUCCH resources in aPUCCH-Config. A PUCCH resource set is provided byPUCCH-ResourceSetand is associated with a PUCCH resource set index provided bypucch-ResourceSetId, with a set of PUCCH resource indexes provided byresourceListthat provides a set ofpucch-ResourceIdused in the PUCCH resource set, and with a maximum number of UCI information bits the UE can transmit using a PUCCH resource in the PUCCH resource set provided bymaxPayloadSize. For the first PUCCH resource set, the maximum number of UCI information bits is 2. A maximum number of PUCCH resource indexes for a set of PUCCH resources is provided bymaxNrofPUCCH-ResourcesPerSet. The maximum number of PUCCH resources in the first PUCCH resource set is 32 and the maximum number of PUCCH resources in the other PUCCH resource sets is 8.

[0262] If the UE transmits OUCIUCI information bits, that include hybrid automatic repeat request acknowledgement (HARQ-ACK) information bits and UEI report bits, the UE could determine a PUCCH resource set to be

[0263] - a first set of PUCCH resources with pucch-ResourceSetId = 0 if OUCI≤2 including 1 or 2 HARQ-ACK information bits and a positive or negative SR on one SR transmission occasion and / or 1 or 2 UEI report bits if transmission of HARQ-ACK information and SR and / or UEI report occurs simultaneously, or

[0264] - a second set of PUCCH resources with pucch-ResourceSetId = 1, if provided by higher layers, if 2 < OUCI≤N2where N2is equal to maxPayloadSize if maxPayloadSize is provided for the PUCCH resource set with pucch-ResourceSetId = 1; otherwise N2is equal to 1706, or

[0265] - a third set of PUCCH resources with pucch-ResourceSetId = 2, if provided by higher layers, if N2<OUCI≤N3where N3is equal to maxPayloadSize if maxPayloadSize is provided for the PUCCH resource set with pucch-ResourceSetId = 2; otherwise N3is equal to 1706, or

[0266] - a fourth set of PUCCH resources with pucch-ResourceSetId = 3, if provided by higher layers, if N3< OUCI≤1706.

[0267] Furthermore, if a UE is not transmitting PUSCH, and the UE is transmitting UCI, the UE could transmit UCI in a PUCCH using

[0268] - PUCCH format 0 if

[0269] - the transmission is over 1 symbol or 2 symbols,

[0270] - the number of HARQ-ACK information bits with positive or negative SR (HARQ-ACK / SR bits) is 1 or 2, and / or

[0271] - the number of UEI report bits is 1 or 2

[0272] - PUCCH format 1 if

[0273] - the transmission is over 4 or more symbols,

[0274] - the number of HARQ-ACK / SR bits is 1 or 2, and / or

[0275] - the number of UEI report bits is 1 or 2

[0276] - PUCCH format 2 if

[0277] - the transmission is over 1 symbol or 2 symbols,

[0278] - the number of UCI bits is more than 2, and / or

[0279] - the number of UEI report bits is 1 or 2

[0280] - PUCCH format 3 if

[0281] - the transmission is over 4 or more symbols,

[0282] - the number of UCI bits, including e.g. UEI report bits, is more than 2,

[0283] - the PUCCH resource does not include an orthogonal cover code, or the UE is provideduseInterlacePUCCH-PUSCHinBWP-UplinkDedicated

[0284] - PUCCH format 4 if

[0285] - the transmission is over 4 or more symbols,

[0286] - the number of UCI bits, including e.g., UEI report bits, is more than 2,

[0287] - the PUCCH resource includes an orthogonal cover code and the UE is not provideduseInterlacePUCCH-PUSCHinBWP-UplinkDedicated

[0288] A UE could first determine a number of UEI report bits OUEIand a corresponding set of PUCCH resources according to those specified herein in the present disclosure. If OUEI=0, the UE may not transmit a PUCCH that only includes UEI report bits.

[0289] In addition, for a PUCCH transmission with UEI report, a UE could determine a PUCCH resource on the cell of the PUCCH transmission, after determining a set of PUCCH resources for OUEIUEI report bits. The PUCCH resource determination could be based on a PUCCH resource indicator field, if present, in a last DCI format, excluding the semi-persistent scheduling (SPS) activation DCI, among one or more DCI formats that provide necessary information related to the UEI report, indicating a same slot for the PUCCH transmission, that the UE detects and for which the UE transmits corresponding UEI report in the PUCCH.

[0290] For the first set of PUCCH resources and when the size RPUCCHof resourceList is larger than eight, when a UE provides UEI report in a PUCCH transmission in response to detecting a last DCI format in a physical downlink control channel (PDCCH) reception, excluding the SPS activation DCI, among one or more DCI formats that provide necessary information related to the UEI report, indicating a same slot for the PUCCH transmission, the UE determines a PUCCH resource with index rPUCCH, 0≤ rPUCCH≤RPUCCH-1, as

[0291]

[0292] where NCCE,pis a number of CCEs in CORESET p of the PDCCH reception for the DCI format, nCCE,pis the index of a first CCE for the PDCCH reception, and is a value of the PUCCH resource indicator field in the corresponding DCI format. When the PDCCH reception includes first and second PDCCH candidates from respective first and second search space sets, the CORESET is associated with the search space set having the smaller index. If

[0293] - the first search space set has larger index than the second search space set and includes the first PDCCH candidate and a third PDCCH candidate that have same first CCE index and CCE aggregation levels 8 and 16, or 16 and 8, respectively,

[0294] - the second search space set includes the second PDCCH candidate that has same index and same CCE aggregation level as the first PDCCH candidate, and a fourth PDCCH candidate that has same index and same CCE aggregation level as the third PDCCH candidate,

[0295] - the CORESET associated with the first search space set hascce-REG-MappingType= 'nonInterleaved' and has duration of one symbol, and

[0296] - the second PDCCH candidate has different first CCE index than the fourth PDCCH candidate

[0297] the UE determines nCCE,0from the PDCCH candidate with CCE aggregation level 16 among the second PDCCH candidate and the fourth PDCCH candidate. If the DCI format does not include a PUCCH resource indicator field, =0.

[0298] If a UE transmits a PUCCH with UEI report using PUCCH format 0, the UE could determine values m0and mCSfor computing a value of cyclic shift α where m0is provided by initialCyclicShift of PUCCH-format0 or, if initialCyclicShift is not provided, by the initial cyclic shift index and mCSis determined from the value of one UEI report bit or from the values of two UEI report bits as specified herein in the present disclosure, respectively.

[0299]

[0300]

[0301] If a UE transmits a PUCCH with UEI report using PUCCH format 1, the UE could be provided a value for m0by initialCyclicShift of PUCCH-format1 or, if initialCyclicShift is not provided, by the initial cyclic shift index.

[0302] If a UE transmits a PUCCH with OUEIUEI report bits and OCRCbits using PUCCH format 2 or PUCCH format 3 in a PUCCH resource that includes physical resource blocks (PRBs), the UE could determine a number of PRBs for the PUCCH transmission to be the minimum number of PRBs, that is smaller than or equal to a number of PRBs provided respectively bynrofPRBsofPUCCH-format2ornrofPRBsofPUCCH-format3and start from the first PRB from the number of PRBs, that results to and, if , and r are defined in clause 9.2.5.2 in the 3GPP TS 38.213 [REF3]. For PUCCH format 3, if is not equal , is increased to the nearest allowed value ofnrofPRBs. If , the UE could transmit the PUCCH over PRBs.

[0303] If a UE is provided a first interlace of PRBs by interlace0 in InterlaceAllocation and transmits a PUCCH with OUCIUEI report bits and OCRCbits using PUCCH format 2 or PUCCH format 3, the UE could transmit the PUCCH over the first interlace if ; otherwise, if the UE is provided a second interlace byinterlace1inPUCCH-format2orPUCCH-format3, the UE could transmit the PUCCH over the first and second interlaces.

[0304] A UE could be be provided by higher layer parameter(s) / signaling(s) a set of configurations for UEI report in a PUCCH transmission using either PUCCH format 0 or PUCCH format 1. Furthermore, the UE can be provided, by phy-PriorityIndex in the higher layer parameter(s) / signaling(s) that provides the set of UEI report configurations, a priority index 0 or a priority index 1 for the UEI report. If the UE is not provided a priority index for UEI report, the corresponding priority index is 0. The UE could also be provided a periodicity UEIreportPERIODICITYin symbols or slots and an offset UEIreportOFFSETin slots by periodicityAndOffset for a PUCCH transmission conveying the UEI report. If UEIreportPERIODICITYis larger than one slot, the UE could determine a transmission occasion for the UEI report (e.g., a trigger / pre-notification message as specified herein in the present disclosure) in a PUCCH to be in a slot with number in a frame with number nfif . Furthermore, if UEIreportPERIODICITYis one slot, the UE could expect or expect that UEIreportOFFSET=0 and every slot is a transmission occasion for the UEI report in a PUCCH. If UEIreportPERIODICITYis smaller than one slot, the UE could determine a transmission occasion for the UEI report in a PUCCH to start in a symbol with index l if (l-l0modUEIreportPERIODICITY)modUEIreportPERIODICITY=0 where l0is the value of startingSymbolIndex.

[0305] For example, if the UE determines that, for a transmission occasion for the UEI report in a PUCCH, the number of symbols available for the PUCCH transmission in a slot is smaller than the value provided by nrofSymbols, the UE may not transmit the PUCCH in the slot. The UEI reporting transmission occasions in a PUCCH could be subject to the limitations for UE transmissions. The UE could transmit a PUCCH in the PUCCH resource for the corresponding configuration for UEI reporting only when the UE transmits a positive UEI report value. For a positive UEI report value transmission using PUCCH format 0, the UE could transmit the PUCCH by obtaining m0as described herein in the present disclosure and by setting mcs=0. For a positive UEI report value transmission using PUCCH format 1, the UE could transmit the PUCCH by setting b(0)=0 according to those specified herein in the present disclosure.

[0306] For another example, if a UE is configured with multiple PUCCH resources in a slot to transmit the UEI reports as specified herein in the present disclosure

[0307] - if the UE is not provided by the network PUCCH resources for transmission of multiple UEI reports or if PUCCH resources for transmissions of the UEI reports do not overlap in the slot, the UE could determine a first resource corresponding to a UEI report with the highest priority

[0308] - if the first resource includes PUCCH format 2, and if there are remaining resources in the slot that do not overlap with the first resource, the UE determines a UEI report with the highest priority, among the UEI reports with corresponding resources from the remaining resources, and a corresponding second resource as an additional resource for the UEI reporting

[0309] - if the first resource includes PUCCH format 3 or PUCCH format 4, and if there are remaining resources in the slot that include PUCCH format 2 and do not overlap with the first resource, the UE determines a UEI report with the highest priority, among the UEI reports with corresponding resources from the remaining resources, and a corresponding second resource as an additional resource for the UEI reporting

[0310] - if the UE is provided by the network PUCCH resources for transmission of multiple UEI reports and if any of the multiple PUCCH resources overlap, the UE could multiplex the UEI reports in a resource from the resources provided by the network as described herein.

[0311] Furthermore, a UE could be provided / indicated / configured by the network, e.g., via higher layer RRC signalling(s) / parameter(s) - e.g., a higher layer parametersimultaneousHARQ-ACK-CSI-UEIreport- and MAC CE command(s) and / or dynamic DCI based L1 signalling(s), to multiplex DL HARQ-ACK information, with or without SR, and / or CSI report(s), and / or UEI report(s) as specified herein in the present disclosure in a same PUCCH; otherwise, the UE drops the CSI report(s) and includes only DL HARQ-ACK information, with or without SR, in the PUCCH, or the UE drops the CSI report(s) and includes the UEI report(s) and / or DL HARQ-ACK information in the PUCCH, with or without SR, or the UE drops the UEI report(s) and includes the CSI report(s) and / or DL HARQ-ACK information, with or without SR, in the PUCCH. If the UE would transmit multiple PUCCHs in a slot that include DL HARQ-ACK information, and / or CSI report(s), and / or UEI report(s) according to those specified herein in the present disclosure, the UE could expect to be provided a same configuration (of)simultaneousHARQ-ACK-CSI-UEIreportfor each of PUCCH formats 2, 3, and 4.

[0312] If a UE would transmit multiple PUCCHs in a slot that include HARQ-ACK information, and / or SR, and / or CSI reports and / or UEI report(s), and any PUCCH with HARQ-ACK information in the slot that satisfies the timing conditions as provided in system specification(s) and does not overlap with any other PUCCH or PUSCH in the slot that does not satisfy the timing conditions as those provided in system specifications, the UE could multiplex the HARQ-ACK information, and / or SR, and / or CSI reports, and / or UEI report(s) as specified herein in the present disclosure, and determine corresponding PUCCH(s) for transmission in the slot according to the following pseudo-code. If the multiple PUCCHs do not include HARQ-ACK information and do not overlap with any PUSCH transmission by the UE in response to a DCI format detection by the UE, the timing conditions provided in the corresponding system specification(s) do not apply.

[0313] If

[0314] - a UE is not providedmulti-CSI-PUCCH-ResourceList, and / or the UE is not provided by the network (e.g., the network 130) PUCCH resources for transmission of multiple UEI reports, and

[0315] - a resource for a PUCCH transmission with HARQ-ACK information in response to SPS PDSCH reception and / or a resource for a PUCCH associated with a SR occasion and / or a resource for a PUCCH associated with a UEI report overlap in time with two resources for respective PUCCH transmissions with two CSI reports, and / or a resource for a PUCCH transmission with HARQ-ACK information in response to SPS PDSCH reception and / or a resource for a PUCCH associated with a SR occasion overlap in time with two resources for respective PUCCH transmissions with one or two CSI reports and / or one or two UEI reports, and

[0316] - there is no resource for a PUCCH transmission with HARQ-ACK information in response to a DCI format detection that overlaps in time with any of the previous resources, and / or there is no resource for a PUCCH transmission with UEI report that overlaps in time with any of the previous resources, and

[0317] - the following pseudo code results to the UE attempting to determine a single PUCCH resource from the HARQ-ACK and / or the SR and / or the UEI report resource and the two PUCCH resources with CSI reports, and / or to determine a single PUCCH resource from the HARQ-ACK and / or the SR resource and the two PUCCH resources with CSI report(s) and / or UEI report(s)

[0318] the UE

[0319] - multiplexes the HARQ-ACK information and / or the SR and / or the UEI report in the resource for the PUCCH transmission with the CSI report having the higher priority, and / or multiplexes the HARQ-ACK information and / or the SR in the resource for the PUCCH transmission with the CSI report and / or the UEI report having the higher priority, and

[0320] - does not transmit the PUCCH with the CSI report having the lower priority, and / or does not transmit the PUCCH with the UEI report having the lower priority.

[0321] Set Q to the set of resources for transmission of corresponding PUCCHs in a single slot without repetitions where

[0322] - a resource with earlier first symbol is placed before a resource with later first symbol

[0323] - for two resources with same first symbol, the resource with longer duration is placed before the resource with shorter duration

[0324] - for two resources with same first symbol and same duration, the placement is arbitrary

[0325] - the three steps herein for the set Q are according to a subsequent pseudo-code for a function order(Q)

[0326] - a resource for negative SR transmission that does not overlap with a resource for HARQ-ACK or CSI transmission or transmission of UEI report(s) is excluded from set Q

[0327] - if the UE (e.g., the UE 116) is not provided simultaneousHARQ-ACK-CSI-UEIreport according to those specified herein in the present disclosure and resources for transmission of HARQ-ACK information and / or UEI report(s) - e.g., including the trigger / pre-notification message as specified herein in the present disclosure - include PUCCH format 0 or PUCCH format 2, resources that include PUCCH format 2, or PUCCH format 3, or PUCCH format 4 for transmission of CSI reports and / or UEI report(s) - e.g., including the content(s) associated to the corresponding trigger / pre-notification message as specified herein in the present disclosure - are excluded from the set Q if they overlap with any resource from the resources for transmission of HARQ-ACK information and / or UEI report(s) - e.g., including the trigger / pre-notification message as specified herein in the present disclosure

[0328] - if the UE is not provided simultaneousHARQ-ACK-CSI-UEIreport according to those specified herein in the present disclosure and at least one of the resources for transmission of HARQ-ACK information and / or UEI report(s) - e.g., including the trigger / pre-notification message as specified herein in the present disclosure - includes PUCCH format 1, PUCCH format 3, or PUCCH format 4

[0329] - resources that include PUCCH format 3 or PUCCH format 4 for transmission of CSI reports and / or UEI report(s) - e.g., including the content(s) associated to the corresponding trigger / pre-notification message as specified herein in the present disclosure - are excluded from the set Q

[0330] - resources that include PUCCH format 2 for transmission of CSI reports and / or UEI report(s) - e.g., including the content(s) associated to the corresponding trigger / pre-notification message as specified herein in the present disclosure - are excluded from the set Q if they overlap with any resource from the resources for transmission of HARQ-ACK information and / or UEI report(s) - e.g., including the trigger / pre-notification message as specified herein in the present disclosure

[0331] Set C(Q) to the cardinality of Q

[0332] Set Q(j,0)to be the first symbol of resource Q(j) in the slot

[0333] Set L(Q(j)) to be the number of symbols of resource Q(j) in the slot

[0334] Set j=0 - index of first resource in set Q

[0335] Set o=0 - counter of overlapped resources

[0336] while j≤C(Q)-1

[0337]

[0338] For each PUCCH resource in the set Q that satisfies the timing conditions provided in the corresponding system specification(s), when applicable,

[0339] - the UE could transmit a PUCCH using the PUCCH resource if the PUCCH resource does not overlap in time with a PUSCH transmission after multiplexing UCI following the procedures specified herein in the present disclosure

[0340] - the UE could multiplex HARQ-ACK information and / or CSI reports and / or UEI report(s) in a PUSCH if the PUCCH resource overlaps in time with a PUSCH transmission, and does not transmit SR and / or UEI report(s). In case the PUCCH resource overlaps in time with multiple PUSCH transmissions, the PUSCH for multiplexing HARQ-ACK information and / or CSI and / or UEI report(s) - e.g., including the trigger / pre-notification message as specified herein in the present disclosure - is selected. If the PUSCH transmission by the UE is not in response to a DCI format detection and the UE multiplexes only CSI reports and / or UEI report(s), the timing conditions are not applicable

[0341] - the UE does not expect the resource to overlap with a second resource of a PUCCH transmission over multiple slots if the resource is obtained from a group of resources that do not overlap with the second resource.

[0342] In one embodiment, UE behaviours / procedures for multiplexing HARQ-ACK and / or CSI and / or SR and / or UEI report(s) in a PUCCH are provided expecting one or more of the followings:

[0343] - resources for transmissions of UCI types, prior to multiplexing or dropping, overlap in a slot

[0344] - multiplexing conditions of corresponding UCI types in a single PUCCH are satisfied, and

[0345] - the UE does not transmit any PUSCH time-overlapping with PUCCH in the slot.

[0346] In one example, a UE could be configured to transmit K PUCCHs for respective K SRs in a slot, as determined by a set of schedulingRequestResourceId, a schedulingRequestResourceId associated with schedulingRequestID-BFR-SCell, a schedulingRequestResourceId associated with schedulingRequestID-BFR, a schedulingRequestResourceId associated with schedulingRequestID-BFR2 if the UE provides twoLRRcapability, and a schedulingRequestResourceId associated with schedulingRequestID-LBT-SCell, with SR transmission occasions that could overlap with a transmission of a PUCCH with HARQ-ACK information from the UE in the slot or with a transmission of a PUCCH with CSI report(s) from the UE in the slot or with a transmission of a PUCCH with UEI report(s) from the UE in the slot. In another example, a UE could be configured to transmit K PUCCHs for respective K UEI reports as specified herein in the present disclosure in a slot, as determined by a set of configurations for the UEI reporting as specified herein in the present disclosure, with transmission occasions for UEI report(s) that could overlap with a transmission of a PUCCH with HARQ-ACK information from the UE in the slot or with a transmission of a PUCCH with CSI report(s) from the UE in the slot or with a SR transmission occasion from the UE in the slot.

[0347] In one example, if a UE would transmit a PUCCH with positive UEI report value and at most two HARQ-ACK information bits in a resource using PUCCH format 0, the UE could transmit the PUCCH in the resource using PUCCH format 0 in PRB(s) for HARQ-ACK information. The UE could determine a value of m0and mCSfor computing a value of cyclic shift α [4, TS 38.211] [REF1]where m0is provided by initialCyclicShift of PUCCH-format0, and mCSis determined from the value of one HARQ-ACK information bit or from the values of two HARQ-ACK information bits as in below Table 10 and Table 11, respectively. Furthermore, if the UE would transmit negative UEI report value and a PUCCH with at most two HARQ-ACK information bits in a resource using PUCCH format 0, the UE could transmit the PUCCH in the resource using PUCCH format 0 for HARQ-ACK information as specified herein in the present disclosure.

[0348]

[0349]

[0350] If a UE would transmit a PUCCH with positive SR and at most two UEI report bits in a resource using PUCCH format 0, the UE could transmit the PUCCH in the resource using PUCCH format 0 in PRB(s) for UEI reporting as described herein in the present disclosure. The UE could determine a value of m0and mCSfor computing a value of cyclic shift α where m0is provided by initialCyclicShift of PUCCH-format0, and mCSis determined from the value of one UEI report bit or from the values of two UEI report bits as in below Table 12 and Table 13, respectively, wherein the UEI report could include at least a trigger / pre-notification message as specified herein in the present disclosure. If the UE would transmit negative SR and a PUCCH with at most two UEI report bits in a resource using PUCCH format 0, the UE could transmit the PUCCH in the resource using PUCCH format 0 for the UEI report(s) according to those specified herein in the present disclosure.

[0351]

[0352]

[0353] In one example, if a UE would transmit SR in a resource using PUCCH format 0 and UEI report bits in a resource using PUCCH format 1 in a slot, the UE could transmit only a PUCCH with the UEI report bits in the resource using PUCCH format 1. In another example, if a UE would transmit UEI report bits in a resource using PUCCH format 0 and HARQ-ACK information bits in a resource using PUCCH format 1 in a slot, the UE could transmit (1) only a PUCCH with the UEI report bits in the resource using PUCCH format 1, or (2) only a PUCCH with the HARQ-ACK information bits in the resource using PUCCH format 1, according to e.g. network’s configuration(s) / indication(s) via higher layer RRC signaling(s) / parameter(s) and / or MAC CE command(s) and / or dynamic DCI based L1 signaling(s), and / or UE’s capability reporting.

[0354] In one example, if the UE would transmit positive SR in a first resource using PUCCH format 1 and at most two UEI report bits in a second resource using PUCCH format 1 in a slot, the UE could transmit a PUCCH with the UEI report bits in the first resource using PUCCH format 1. If a UE would not transmit a positive SR in a resource using PUCCH format 1 and would transmit at most two UEI report bits in a resource using PUCCH format 1 in a slot, the UE could transmit a PUCCH in the resource using PUCCH format 1 for UEI reporting as specified herein in the present disclosure. In another example, if the UE would transmit positive UEI report value in a first resource using PUCCH format 1 and at most two HARQ-ACK information bits in a second resource using PUCCH format 1 in a slot, the UE could transmit, (1) a PUCCH with HARQ-ACK information bits in the first resource using PUCCH format 1, or (2) a PUCCH with UEI report bits in the first resource using PUCCH format 1, according to e.g. network’s configuration(s) / indication(s) via higher layer RRC signaling(s) / parameter(s) and / or MAC CE command(s) and / or dynamic DCI based L1 signaling(s), and / or UE’s capability reporting. If a UE would not transmit a positive UEI report value in a resource using PUCCH format 1 and would transmit at most two HARQ-ACK information bits in a resource using PUCCH format 1 in a slot, the UE could transmit (1) a PUCCH in the resource using PUCCH format 1 for HARQ-ACK information, or (2) a PUCCH in the resource using PUCCH format 1 for UEI reporting, according to e.g. network’s configuration(s) / indication(s) via higher layer RRC signaling(s) / parameter(s) and / or MAC CE command(s) and / or dynamic DCI based L1 signaling(s), and / or UE’s capability reporting.

[0355] In one example, if a UE would transmit a PUCCH with OUEIUEI report bits in a resource using PUCCH format 2 or PUCCH format 3 or PUCCH format 4 in a slot, as described herein in the present disclosure, bits representing a negative or positive SR, in ascending order of the values of schedulingRequestResourceId, a schedulingRequestResourceId associated with schedulingRequestID-BFR-SCell, a schedulingRequestResourceId associated with schedulingRequestID-BFR, a schedulingRequestResourceId associated with schedulingRequestID-BFR2 if the UE provides twoLRRcapability, and a schedulingRequestResourceId associated with schedulingRequestID-LBT-SCell, could be appended to the UEI report bits and the UE could transmit the combined OUCI=OUEI+ UCI bits in a PUCCH using a resource with PUCCH format 2 or PUCCH format 3 or PUCCH format 4 that the UE determines as described herein in the present disclosure. If one of the SRs is a positive LRR, the value of the bits indicates the positive LRR. An all-zero value for the bits represents a negative SR value across K SRs.

[0356] In another example, if a UE would transmit a PUCCH with OACKHARQ-ACK information bits in a resource using PUCCH format 2 or PUCCH format 3 or PUCCH format 4 in a slot, bits representing (positive / negative value of) a UEI report could be appended to the HARQ-ACK information bits and the UE could transmit the combined OUCI=OACK+ UCI bits in a PUCCH using a resource with PUCCH format 2 or PUCCH format 3 or PUCCH format 4 that the UE determines as described herein in the present disclosure. For this case / design example, an all-zero value for the bits could represent a negative UEI report value across L UEI reports.

[0357] In another example, if a UE would transmit a PUCCH with OCSICSI report bits in a resource using PUCCH format 2 or PUCCH format 3 or PUCCH format 4 in a slot, bits representing (positive / negative value of) a UEI report could be prepended to the CSI information bits and the UE could transmit a PUCCH with the combined OUCI= + OCSIUCI bits in a resource using the PUCCH format 2 or PUCCH format 3 or PUCCH format 4 for CSI reporting.

[0420] If the PUSCH transmission is with a configured grant and the UE is providedCG-UCI-OnPUSCH= 'semiStatic', the UE applies the value that is provided byCG-UCI-OnPUSCH = 'semiStatic'for the corresponding UEI report(s).

If the UE is configured byuci-MuxWithDiffPrioto multiplex the UE-initiated (UEI) report(s) of priority 1, the UE applies corresponding provided by the first value ofbetaOffsetsCrossPri1= 'dynamic'.

[0424] Offsets for multiplexing UEI report(s) with priority 0 in a PUSCH transmission with priority 1 are configured to values according to above Table 14. The first, second and third values provided by any ofbetaOffsetsCrossPri0, betaOffsetsCrossPri0DCI-0-2, betaOffsetsCrossPri1DCI-0-3, orcg-betaOffsetsCrossPri0respectively provide indexes for the UE to use if the UE multiplexes up to 2 bits, more than 2 and up to 11 bits, and more than 11 bits of UEI report(s) with priority 0 in the PUSCH transmission with priority 1, respectively.

[0425] Offsets for multiplexing UEI report(s) with priority 1 in a PUSCH transmission with priority 0 are configured to values according to above Table 14.

The beta_offset indicator field indicates a value and / or a value, and / or a value from the respective sets of values, with the mapping defined in above Table 15 and in above Table 16 provided herein in the present disclosure. If the PUSCH transmission has priority 0 or priority 1, and the UE is provideduci-MuxWithDiffPrio, and the UE multiplexes the UEI report(s) of priority 1 or priority 0 in the PUSCH, the UE applies the {first, second, third} values provided bybetaOffsetsCrossPri1= 'dynamic'for DCI format 0_1,betaOffsetsCrossPri1DCI-0-2= 'dynamic'for DCI format 0_2, orbetaOffsetsCrossPri1DCI-0-3= 'dynamic'for DCI format 0_3, or applies the {first, second, third} values provided bybetaOffsetsCrossPri0 = 'dynamic'for DCI format 0_1,betaOffsetsCrossPri0DCI-0-2= 'dynamic'for DCI format 0_2, orbetaOffsetsCrossPri0DCI-0-3= 'dynamic'for DCI format 0_3.

[0427] For a PUSCH transmission that is configured by aConfiguredGrantConfigand includes CG-UCI, the UE multiplexes the CG-UCI in the PUSCH transmission using a value provided bybetaOffsetCG-UCIwith the mapping defined in above Table 14. The CG-UCI has same priority value as the PUSCH. If the UE is providedcg-UCI-Multiplexingand multiplexes UEI report(s) of same priority value as the CG-UCI in the PUSCH transmission, the UE jointly encodes the UEI report(s) and the CG-UCI and determines a number of resources for multiplexing the combined information in a PUSCH using which provides indexes and for the UE to use if the UE multiplexes up to 11, and more than 11 combined information bits, respectively.

[0428] For a PUSCH transmission that is configured by aConfiguredGrantConfigand includes UTO-UCI, the UE multiplexes the UTO-UCI in the PUSCH transmission using a value provided bybetaOffsetUTO-UCIwith the mapping defined in above Table 14. The UTO-UCI has same priority value as the PUSCH. If the UE multiplexes UEI report(s) of same priority value as the UTO-UCI in the PUSCH transmission, the UE jointly encodes the corresponding UEI report(s) and the UTO-UCI and determines a number of resources for multiplexing the combined information in the PUSCH using which provides indexes and for the UE to use if the UE multiplexes up to 11, and more than 11 combined information bits, respectively.

[0429] In (up to Rel.17) NR specification, the most resource-efficient reporting mechanism for a content (e.g. beam, CSI etc., or in general different report quantities) is aperiodic (in conjunction with aperiodic CSI-RS). On the other hand, with a well-chosen periodicity, periodic reporting (followed by semi-persistent) results in the lowest latency at the expense of resources. Although aperiodic reporting seems preferred from the overall operational perspective, in a few relevant scenarios the NW / gNB lacks knowledge on the DL channel condition - or, in other words, the UE knows the DL channel condition better. In this case, it is clearly beneficial if the UE can initiate its own aperiodic reporting for a content (e.g. beam, CSI etc.) or trigger a beam switching for a condition or event. For instance, when the UE is configured only with aperiodic beam reporting and the channel condition is worsened to the point of beam failure, the loss of link due to beam failure can be avoided if the UE can transmit an aperiodic beam report without having to wait for a beam report request / trigger from the NW / gNB or trigger a new beam update without having to wait for a beam change or update indication from the NW / gNB. Likewise, when the UE is configured only with aperiodic CSI reporting and the channel condition is worsened due to UE speed / movement, the performance degradation due to faster link quality degradation can be avoided if the UE can transmit an aperiodic CSI report without having to wait for a CSI request / trigger from the NW / gNB or trigger a new beam update without having to wait for a beam change or update indication from the NW / gNB. Such UE-initiated reporting and / or beam switching for a content can be enabled for other types of report quantities (different from common beam or CSI reports) and application scenarios.

[0430] Although UE-initiated reporting and / or beam switching and / or beam activation / deactivation can be beneficial, efficient designs are needed to ensure that the latency is reduced and, at the same time, error events can be minimized. Therefore, there is a need for efficient designs for UE-initiated reporting and / or beam switching and / or beam activation / deactivation for a content that can offer good trade-off between latency and reliability, in particular, when the UE-initiated beam management framework can include multiple report types (or report quantities), or / and multiple event types when a report types can be associated with an event (e.g. for beam report, the event can be beam failure, and for CSI, the event can be user throughput degradation or increasing retransmission rate).

[0431] The present disclosure provides various detailed design examples on the UE-initiated beam management framework including UE-initiated / triggered beam / CSI reporting and / or UE-initiated / triggered beam switching and / or UE-initiated / triggered beam activation / deactivation / sub-selection. To better support / enable the UE-initiated and the event-based beam operations, this disclosure presents example embodiments on means of transmitting the UE-initiated report(s) along with its indicator(s) via various uplink channels.

[0432] In one example, when there is no content associated with a pre-notification (PN) message / trigger, i.e., the report-type is (A), the trigger / pre-notification message could simply provide a 'hint / alarm / cue' to the target entity (or purpose of the PN message / trigger as specified herein in the present disclosure) according to at least one of the following examples.

[0433] - For example, the hint (or purpose of the PN message / trigger as specified herein in the present disclosure) is about the communication link / channel. For example, it can imply a need for a new or updated report (e.g. beam or CSI or TDCP). In this case, it is up to NW whether to configure a report for the content (separately).

[0434] - For another example, the hint (or purpose of the PN message / trigger as specified herein in the present disclosure) is about an RS transmission. For example, it can imply a need for an aperiodic or semi-persistent RS (e.g. CSI-RS, SRS) transmission. The RS transmission can be from the target entity, or from the UE.

[0435] - For another example, the hint (or purpose of the PN message / trigger as specified herein in the present disclosure) is about a selection / switch. For example, it can imply a need for switching from current A to another A, where A is one of current panel(s), TRP(s) / RRH(s), resource sets, antenna groups, antenna port groups.

[0436] - For another example, the hint (or purpose of the PN message / trigger as specified herein in the present disclosure) is about beam / CSI parameters. For example, the parameter can be codebook type (e.g. from Type I to Type II or vice versa), or rank restriction (e.g. from high rank to low rank or vice versa).

[0437] - For another example, the hint (or purpose of the PN message / trigger as specified herein in the present disclosure) is about RS parameters. For example, the parameter can be related to a AP RS trigger, or RS periodicity, or number of SRS ports (panel switch, 1 panel to 2 panel or vice versa) or number of RS resources.
