Description

METHOD AND APPARATUS FOR UE-INITIATED BEAM REPORTING

[0001] The present disclosure relates generally to wireless communication systems and, more specifically, the present disclosure relates to methods and apparatus for indication of UE-Initiated beam 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 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] Wireless communication has been one of the most successful innovations in modern history. Recently, the number of subscribers to wireless communication services exceeded five billion and continues to grow quickly. The demand of wireless data traffic is rapidly increasing due to the growing popularity among consumers and businesses of smart phones and other mobile data devices, such as tablets, "note pad" computers, net books, eBook readers, and machine type of devices.

The descriptions of FIGS. 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.

[0032] FIG. 1 illustrates an example wireless network 100 according to an embodiment of the present disclosure. The embodiment of the wireless network 100 shown in FIG. 1 is for illustration only. Other embodiments of the wireless network 100 could be used without departing from the scope of this disclosure.

[0033] As shown in FIG. 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.

[0034] 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.

[0035] 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 3rd generation 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).

[0036] 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.

[0037] As described in more detail below, one or more of the UEs 111-116 include circuitry, programing, or a combination thereof for performing indication for UE-Initiated beam reporting. In certain embodiments, one or more of the BSs 101-103 include circuitry, programing, or a combination thereof to support indication for UE-Initiated beam reporting.

[0038] Although FIG. 1 illustrates one example of a wireless network, various changes may be made to FIG. 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.

[0039] FIG. 2 illustrates an example gNB 102 according to an embodiment of the present disclosure. The embodiment of the gNB 102 illustrated in FIG. 2 is for illustration only, and the gNBs 101 and 103 of FIG. 1 could have the same or similar configuration. However, gNBs come in a wide variety of configurations, and FIG. 2 does not limit the scope of this disclosure to any particular implementation of a gNB.

[0040] As shown in FIG. 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.

[0041] 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.

[0042] 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.

[0043] 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. As another example, the controller / processor 225 could support methods for indication of UE-Initiated beam reporting. Any of a wide variety of other functions could be supported in the gNB 102 by the controller / processor 225.

[0044] The controller / processor 225 is also capable of executing programs and other processes resident in the memory 230, such as to support indication for UE-Initiated beam reporting. The controller / processor 225 can move data into or out of the memory 230 as required by an executing process.

[0045] 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.

[0046] 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.

[0047] Although FIG. 2 illustrates one example of gNB 102, various changes may be made to FIG. 2. For example, the gNB 102 could include any number of each component shown in FIG. 2. Also, various components in FIG. 2 could be combined, further subdivided, or omitted and additional components could be added according to particular needs.

[0048] FIG. 3 illustrates an example UE 116 according to an embodiment of the present disclosure. The embodiment of the UE 116 illustrated in FIG. 3 is for illustration only, and the UEs 111-115 of FIG. 1 could have the same or similar configuration. However, UEs come in a wide variety of configurations, and FIG. 3 does not limit the scope of this disclosure to any particular implementation of a UE.

[0049] As shown in FIG. 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.

[0050] 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).

[0051] 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.

[0052] 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.

[0053] 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 for performing indication for UE-Initiated beam 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.

[0054] 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.

[0055] 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).

[0056] Although FIG. 3 illustrates one example of UE 116, various changes may be made to FIG. 3. For example, various components in FIG. 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 FIG. 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.

[0057] FIG. 4A and FIG. 4B illustrate an example of wireless transmit and receive paths 400 and 450, respectively, according to an embodiment 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 is configured to transmit indication for UE-Initiated beam reporting as described in embodiments of the present disclosure. In some embodiments, the receive path 450 is configured to receive indication for UE-Initiated beam reporting as described in embodiments of the present disclosure.

[0058] As illustrated in FIG. 4A, the transmit path 400 includes a channel coding and modulation block 405, 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.

[0059] 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.

[0060] As illustrated in FIG. 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.

[0061] 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.

[0062] Each of the components in FIGS. 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 FIGS. 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.

[0063] 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.

[0064] Although FIGS. 4A and 4B illustrate examples of wireless transmit and receive paths 400 and 450, respectively, various changes may be made to FIGS. 4A and 4B. For example, various components in FIGS. 4A and 4B can be combined, further subdivided, or omitted and additional components can be added according to particular needs. Also, FIGS. 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.

[0065] In embodiments of the present disclosure, a beam is determined by either a transmission configuration indicator (TCI) state that establishes a quasi-colocation (QCL) relationship between a source reference signal (RS) (e.g., single sideband (SSB) and / or Channel State Information Reference Signal (CSI-RS)) and a target RS or a spatial relation information that establishes an association to a source RS, such as SSB or CSI-RS or sounding reference signal (SRS). In either case, the ID of the source reference signal identifies the beam. The TCI state and / or the spatial relation reference RS can determine a spatial RX filter for reception of downlink channels at the UE 116, or a spatial TX filter for transmission of uplink channels from the UE.

[0066] As illustrated in FIG. 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 FIG. 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 FIG. 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 FIG. 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.

[0067] FIG. 5B illustrates an example of a multi-beam operation 550 according to an embodiment of the present disclosure. For example, the multi-beam operation 550 can be utilized by gNB 102 of FIG. 2. This example is for illustration only and other embodiments can be used without departing from the scope of the present disclosure.

[0068] In a wireless system, a device can transmit and / or receive on multiple beams. This is known as "multi-beam operation". While FIG. 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.

[0069] FIG. 6 illustrates an example of a transmitter structure 600 for beamforming according to an embodiment 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.

[0070] Accordingly, embodiments of the present disclosure recognize that Rel-14 LTE and Rel-15 NR support up to 32 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 FIG. 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-PORT analog 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.

[0071] Since the transmitter structure 600 of FIG. 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 FIG. 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.

[0072] 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 (e.g., the BS 102) 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.

[0073] 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. Accordingly, embodiments of the present disclosure recognize that 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).

[0074] The present disclosure provides various aspects and 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 and / or procedures of transmitting the UE-initiated report(s) along with its indicator(s) via various uplink channels, and configuring and determining measurement RS resource(s) for the UE-initiated beam operations. This disclosure also specifies various resource allocation and indication methods for the UE-initiated beam operations.

[0075] 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

[0076] - (A) includes an initiator / trigger / pre-notification

[0077] - (B) includes a report / content (comprising one or multiple report quantities)

[0078] - (C) includes both a trigger / pre-notification message and a (corresponding) report / content

[0079] The UE could send to the network (e.g., the network 130) the UE-initiated (UEI) / UE-triggered report of a (report-)type (A), (B) and / or (C) according to one or more of:

[0080] - Fixed rule(s) in system specification(s): for example, the UE could send to the network a UEI report of a (report-)type (A), or a (report-)type (B), or a (report-)type (C), or a (report-)type (A) followed by a (report-)type (B).

[0081] - 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 downlink control information (DCI) based L1 signaling(s), based on / according to a corresponding UE's capability reporting: for example, the UE could receive from 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), a 2-bit indicator with '00' indicating a UEI report of a (report-)type (A), '01' indicating a UEI report of a (report-)type (B), '10' indicating a UEI report of a (report-)type (C), and '11' indicating a UEI report of a (report-)type (A) followed by a (report-)type (B).

[0082] - UE's autonomous determination, which could be further sent to the network, e.g., via / in part of a beam / CSI report or UE's capability signaling(s).

[0083] 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:

[0084] - In one example, the content includes beam-related quantity / quantities. For example, up to indicators or pairs of

[0085] { }, where is an beam (source RS) indicator (e.g. CRI, SSB resource indicator (SSBRI)) and is a beam metric (e.g. L1-reference signal received power (RSRP) / L1-signal-to-interference-plus-noise ratio (SINR)).

[0086] - 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).

[0087] - In one example, the content includes 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).

[0088] - In one example, the content includes other (e.g. non-beam, non-CSI, non-TDCP) quantity / quantities.

[0089] * In one example, quantity / quantities comprises a selector / indicator indicating selection of one (or >1) of either

[0090] ● beam (TCI state) TCI states (e.g. DL TCI state, UL TCI state, or unified (joint) DL / UL TCI state), or

[0091] ● panel(s) (e.g. UE panels for DL reception or / and UL transmission), or

[0092] ● antenna(e) (e.g. UE antennae for DL reception or / and UL transmission), or

[0093] ● antenna port(s) (e.g. UE antenna ports for DL reception or / and UL transmission).

[0094] * 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 SRS ports to SRS ports, where (e.g. this switching is for DL reception or / and UL transmission).

[0095] - In one example, the content includes beam-related quantity / quantities (examples herein) and at least one other quantity / quantities (examples herein).

[0096] - In one example, the content includes CSI-related quantity / quantities (examples herein) and at least one other quantity / quantities (examples herein).

[0097] - In one example, the content includes TDCP-related quantity / quantities (examples herein) and at least one other quantity / quantities (examples herein).

[0098] - In one example, the content includes beam-related quantity / quantities (examples herein) and CSI-related quantity / quantities (examples herein).

[0099] - In one example, the content includes beam-related quantity / quantities (examples herein) and TDCP-related quantity / quantities (examples herein).

[0100] - In one example, the content includes TDCP-related quantity / quantities (examples herein) and CSI-related quantity / quantities (examples herein).

[0101] In one example, the report is targeting a physical layer (L1) communication (e.g. L1 DL / UL, or L1 SL), i.e. such reporting is to enable fast / reliable DL / UL or SL transmission / reception.

[0102] In one example, the link / channel between the target entity and the UE is a Uu interface (i.e. DL, UL).

[0103] 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.

[0104] 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.

[0105] 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.

[0106] In one example, such reporting can be non-event-based or event-based, based on report-type.

[0107] In one example, such reporting can be non-event-based or event-based, based on a configuration.

[0108] A few examples of the event-types and the report-types are provided in 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 Table 4. A few examples of the autonomous UE-initiated report are shown in Table 5.

[0118]

[0119] 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.

[0120] - 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).

[0121] - 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.

[0122] - 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.

[0123] - 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).

[0124] - 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.

[0125] - For another example, the hint (or purpose of the PN message / trigger as specified herein in the present disclosure) is about transmission scheme, which can be one of PMI-based, diversity (cyclic delay diversity (CDD), cycling, space frequency block code (SFBC)), reciprocity (non-codebook (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).

[0126] - For another example, the hint (or purpose of the PN message / trigger as specified herein in the present disclosure) is about transmission parameters, e.g. modulation and coding scheme (MCS), or number of carrier waves (CWs).

[0127] - 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 physical uplink shared channel (PUSCH)), or reserved for the UE-initiated report, or via a random access channel (RACH) procedure.

[0128] - For another example, the pre-notification (PN) message / trigger is to initiate or request or notify to the network (or the hint / purpose of the PN message / trigger as specified herein in the present disclosure is about) a transmission of a (beam) report / content - e.g., associated to the PN message / trigger, which could comprise one or more report quantities as specified / described herein in the present disclosure.

[0129] In the present disclosure, the UE could determine one or more purposes of the PN message / trigger and send the corresponding PN message(s) / trigger(s) to the network according to one or more of:

[0130] - Fixed rule(s) in system specification(s): for example, the PN message is used to initiate or request or notify to the network (or the purpose of the PN message is about) a transmission of a (beam) report / content, which could comprise one or more indicators / triggers and / or report quantities as specified / described herein in the present disclosure.

[0131] - 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), based on / according to a corresponding UE's capability signaling: for example, the UE could receive from 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), one or more indicators indicating one or more of the purposes of the PN message / trigger as specified herein in the present disclosure; for another example, the UE could be first higher layer RRC configured / provided by the network a list / set / pool of purposes of PN / trigger according to those specified herein in the present disclosure; the UE could then receive from the network a MAC CE / DCI to activate / indicate one or more purposes of the PN / trigger from the configured list / set / pool.

[0132] - UE's autonomous determination, which could be further sent to the network, e.g., via / in part of a beam / CSI report or UE's capability signaling(s).

[0133] In one example, when a UE could or is able to or is configured to send to the network a UEI report comprising at least a pre-notification message / trigger - e.g., of (report-)type (A) or (report-)type (C) as specified herein in the present disclosure, and / or the (corresponding) content - e.g., of (report-)type (B) or (report-)type (C) as specified herein in the present disclosure, the UE could send to the network a pre-notification (PN) message / trigger and / or the corresponding content(s) according to one or more of:

[0134] - Fixed rule(s) in system specification(s): for example, the UE could send to the network a UEI report comprising only a PN message, or comprising only a content according to those specified herein in the present disclosure, or comprising both a PN message and a corresponding content.

[0135] - 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), based on / according to a corresponding UE's capability reporting: for example, the UE could receive from 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), a 2-bit indicator with '00' indicating a UEI report comprising only a PN message, '01' indicating a UEI report comprising only a content according to those specified herein in the present disclosure, '10' / '11' indicating a UEI report comprising both a PN message and a corresponding content.

[0136] - UE's autonomous determination, which could be further sent to the network, e.g., via / in part of a beam / CSI report or UE's capability signaling(s).

[0137] In one example, when a UE could or is able to or is configured to send to the network a UEI report comprising at least a pre-notification message / trigger - e.g., of (report-)type (A) or (report-)type (C) as specified herein in the present disclosure, and / or the (corresponding) content - e.g., of (report-)type (B) or (report-)type (C) as specified herein in the present disclosure, the UE could send to the network a pre-notification (PN) message / trigger and the corresponding content(s) via / in a same report / reporting instance / transmission / transmission occasion (e.g., via / in a same set of uplink resources including PUCCH(s), PUSCH(s), MAC CE(s), PRACH(s) and etc.) or different reports / reporting instances / transmissions / transmission occasions (e.g., via / in different sets of uplink resources including PUCCH(s), PUSCH(s), MAC CE(s), PRACH(s) and etc.) according to one or more of:

[0138] - Fixed rule(s) in system specification(s): for example, the UE (e.g., the UE 116) could send to the network UEI report(s) comprising a pre-notification (PN) message / trigger and the corresponding content(s) via / in a same report / reporting instance / transmission / transmission occasion (e.g., via / in a same set of uplink resources including PUCCH(s), PUSCH(s), MAC CE(s), PRACH(s) and etc.), or the UE could send to the network UEI report(s) comprising a pre-notification (PN) message / trigger and the corresponding content(s) via / in different reports / reporting instances / transmissions / transmission occasions (e.g., via / in different sets of uplink resources including PUCCH(s), PUSCH(s), MAC CE(s), PRACH(s) and etc.).

[0139] - 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), based on / according to a corresponding UE's capability reporting: for example, the UE could receive from 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), a one-bit indicator with '0' (or '1') indicating that the UE could send to the network UEI report(s) comprising a pre-notification (PN) message / trigger and the corresponding content(s) via / in a same report / reporting instance / transmission / transmission occasion (e.g., via / in a same set of uplink resources including PUCCH(s), PUSCH(s), MAC CE(s), PRACH(s) and etc.), and '1' (or '0') indicating that the UE could send to the network UEI report(s) comprising a pre-notification (PN) message / trigger and the corresponding content(s) via / in different reports / reporting instances / transmissions / transmission occasions (e.g., via / in different sets of uplink resources including PUCCH(s), PUSCH(s), MAC CE(s), PRACH(s) and etc.).

[0140] - UE's autonomous determination, which could be further sent to the network, e.g., via / in part of a beam / CSI report or UE's capability signaling(s).

[0141] The indicator(s) / trigger(s) described herein in the present disclosure could correspond to (or could be in part of) the trigger / pre-notification (PN) message in a (report-)type (A) based report or a (report-)type (C) based report, or could correspond to (or could be in part of) the (corresponding) content in a (report-)type (B) based report or a (report-)type (C) based report.

[0264] * Yet for another example, a custom / purpose designed DCI format could be used to indicate to the UE a beam (i.e., a TCI state and / or a TCI state ID) for the transmission / reception of a PDCCH or a PDSCH.

[0265] Rel-17 introduced the unified TCI framework, where a unified or master or main TCI state is signaled to the UE. The unified or master or main TCI state can be one of:

[0266] - In case of joint TCI state indication, wherein a same beam is used for DL and UL channels, a joint TCI state that can be used at least for UE-dedicated DL channels and UE-dedicated UL channels.

[0267] - In case of separate TCI state indication, wherein different beams are used for DL and UL channels, a DL TCI state can be used at least for UE-dedicated DL channels.

[0268] - In case of separate TCI state indication, wherein different beams are used for DL and UL channels, a UL TCI state can be used at least for UE-dedicated UL channels.

[0269] The unified (master or main) TCI state is TCI state of UE-dedicated reception on PDSCH / PDCCH or dynamic-grant / configured-grant based PUSCH and dedicated PUCCH resources.

[0270] In a single-TRP system, a UE could be indicated / provided / configured by the network (e.g., the network 130), e.g., via a beam indication MAC CE or a DCI (e.g., via one or more TCI codepoints of one or more TCI fields in the corresponding DCI 1_1 / 1_2 with or without DL assignment), a TCI state / pair of TCI states for at least UE-dedicated reception on PDSCH / PDCCH or dynamic-grant / configured-grant based PUSCH or dedicated PUCCH resources, wherein a TCI state could be a joint DL and UL TCI state or a separate DL TCI state provided by TCI-State / DLorJointTCI-State, or a separate UL TCI state provided by TCI-State / UL-TCIState, and a pair of TCI states could include / contain a separate DL TCI state provided by TCI-State / DLorJointTCI-State or a separate UL TCI State provided by TCI-State / UL-TCIState, under the unified TCI framework.

[0286] - (implicit determination): One or more first RSs or RS resources or RS resource indexes quasi-co-located (QCL'ed) with, e.g., of QCL-TypeD, one or more second RSs or RS resources or RS resource indexes provided in / by one or more TCI states provided / configured in a higher layer RRC configured list of TCI state(s), wherein the list of TCI state(s) could correspond to a list of joint / DL TCI state(s) provided by DLorJointTCI-State, and each of the TCI state(s) in the list could be a joint / DL TCI state provided by TCI-State; in this case, the one or more first RSs or RS resources or RS resource indexes could be or could serve as the QCL root / source RS(s) for the second RS(s) / RS resource(s) / RS resource index(es) provided in / by one or more of the joint / DL TCI state(s) in the list of TCI state(s), and the first RS(s) / RS resource(s) / RS resource index(es) could correspond to synchronization signal / physical broadcast channel (SS / PBCH) block(s) - SSB(s) or SSB index(es), and / or the second RS(s) / RS resource(s) / RS resource index(es) could be CSI-RS(s) / CSI-RS resource(s) / CSI-RS resource configuration index(es) including TRS(s).

[0287] In the present disclosure, the UE could be indicated or configured or provided 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) based on or according to a corresponding UE's capability or capability signaling, which one or more of the implicit determinations and explicit configuration as specified / defined herein in the present disclosure to use or follow or apply for determining or identifying the actual candidate / new beam RS(s) or RS resource(s) or RS resource index(es). For instance, a higher layer parameter candidateBeamRSDetermination could be provided in the higher layer parameter(s) CSI-ReportConfig, CSI-ResourceConfig, UEI-ResourceConfig and / or UEI-ReportConfig that configures or provides information related to or for the UEI beam reporting. When / if the higher layer parameter candidateBeamRSDetermination is set to 'CSIRS', the UE could follow those specified or described in the implicit determination to determine or identify the actual candidate / new beam RS(s) or RS resource(s) or RS resource index(es). When / if the higher layer parameter candidateBeamRSDetermination is set to 'SSB', the UE could follow those specified or described in the implicit determination to determine or identify the actual candidate / new beam RS(s) or RS resource(s) or RS resource index(es).

[0288] Furthermore, the UE could identify or determine a subset of the candidate RS(s) or RS resource(s), or RS resource index(es) configured following those specified / described in the explicit configuration and / or determined following those specified / described in the one or more implicit determinations described herein as the RS(s) or RS resource(s) or RS resource index(es) for the actual measurement for / of one or more candidate / new beams.

[0289] - In one example, the UE could be indicated or configured or provided 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) according to or based on a corresponding UE's capability or capability signaling, one or more indicators to indicate which one or more of the candidate RS(s) or RS resource(s) or RS resource index(es) and / or the subset of the candidate RS(s) or RS resource(s) or RS resource index(es) to use / apply as the RS(s) or RS resource(s) or RS resource index(es) for the actual measurement for / of the one or more candidate / new beams.

[0290] * For example, the one or more indicators could be or could correspond to a set of RS resource index(es) - e.g., a set of CSI-RS resource configuration index(es) and / or SSB index(es). For this design example, each of the RS resource index(es) in the set could correspond / point to or represent a candidate RS / RS resource / RS resource index or one of the candidate RS(s) or RS resource(s) or RS resource index(es). In this case, the UE could determine or identify that the candidate RS(s) or RS resource(s) or RS resource index(es) associated / corresponding to or pointed / represented by the RS resource index(es) in the set could be used / applied as the RS(s) or RS resource(s) or RS resource index(es) for the actual measurement for / of one or more candidate / new beams. For instance, for a set of K 1 candidate RS resource indexes {RS index #1, RS index #2, ..., RS index #K} configured / provided by the network (following those described / specified in the one or more explicit configuration described herein in the present disclosure), the one or more indicators (or equivalently, the set of RS resource index(es)) could provide or indicate or contain or include or comprise one or more indexes each belonging to {1, ..., K}. Specifically, when / if the RS resource indexes in the set correspond to {1, 2, K}, the RSs or RS resources corresponding / associated to the RS index #1, RS index #2 and RS index #K in the set could be used / applied as the RS(s) or RS resource(s) for the actual measurement for / of the one or more candidate / new beams.

[0291] * For another example, the one or more indicators could be or could correspond to a bitmap with each entry / bit position of the bitmap corresponding / associated to a candidate RS / RS resource / RS resource index or one of the candidate RS(s) or RS resource(s) or RS resource index(es). In this case, when / if an entry / bit position of the bitmap is set to '1' (or '0'), the UE could determine or identify that the candidate RS(s) or RS resource(s) or RS resource index(es) associated / corresponding to the entry / bit position could be used / applied as the RS(s) or RS resource(s) or RS resource index(es) for the actual measurement for / of one or more candidate / new beams. For instance, for a set of K 1 candidate RS resource indexes {RS index #1, RS index #2, ..., RS index #K} configured / provided by the network (following those described / specified in the one or more explicit configurations described herein in the present disclosure), the entries / bit positions in the bitmap associated / corresponding to the RS index #1, RS index #2 and RS index #K are set to '1's while the entry(s) / bit position(s) in the bitmap associated / corresponding to the RS index(es) other than the RS index #1, RS index #2 and RS index #K are set to '0's. In this case, the RSs or RS resources corresponding / associated to the RS index #1, RS index #2 and RS index #K in the set corresponding / associated to the entries / bit positions in the bitmap that are set to '1's could be used / applied as the RS(s) or RS resource(s) for the actual measurement for / of the one or more candidate / new beams.

[0292] * For another example, the one or more indicators could be or could correspond to one or more 1-bit indicators each corresponding / associated to a candidate RS / RS resource / RS resource index or one of the candidate RS(s) or RS resource(s) or RS resource index(es). In this case, when / if a 1-bit indicator is set to '1' (or '0'), the UE could determine or identify that the candidate RS(s) or RS resource(s) or RS resource index(es) associated / corresponding to the 1-bit indicator could be used / applied as the RS(s) or RS resource(s) or RS resource index(es) for the actual measurement for / of one or more candidate / new beams. For instance, for a set of K 1 candidate RS resource indexes {RS index #1, RS index #2, ..., RS index #K} configured / provided by the network (following those described / specified in the one or more explicit configurations described herein in the present disclosure), the 1-bit indicators associated / corresponding to the RS index #1, RS index #2 and RS index #K are set to '1's while the 1-bit indicators associated / corresponding to the RS index(es) other than the RS index #1, RS index #2 and RS index #K are set to '0's. In this case, the RSs or RS resources corresponding / associated to the RS index #1, RS index #2 and RS index #K in the set corresponding / associated to the 1-bit indicators that are set to '1's could be used / applied as the RS(s) or RS resource(s) for the actual measurement for / of the one or more candidate / new beams.

[0293] - In another example, the UE could determine or identify which one or more of the candidate RS(s) or RS resource(s) or RS resource index(es) and / or the subset of the candidate RS(s) or RS resource(s) or RS resource index(es) to use / apply as the RS(s) or RS resource(s) or RS resource index(es) for the actual measurement for / of the one or more candidate / new beams according to one or more of the followings, based on e.g. (1) fixed rule(s) in system specification(s) or per RRC (re)configuration, (ii) network's configuration(s) or indication(s) via higher layer RRC signaling(s) / parameter(s) and / or MAC CE command(s) and / or dynamic DCI based L1 signaling(s) based on or according to a corresponding UE's capability or capability signaling, and / or (iii) UE's autonomous determination or selection.

[0294] * For example, the first (or last) L 1 candidate RS(s) or RS resource(s) or RS resource index(es) or the L 1 candidate RS(s) or RS resource(s) with the lowest (or highest) resource index(es) - among the K configured / determined candidate RS(s) or RS resource(s) or RS resource index(es) with L K - could be used / applied as the RS(s) or RS resource(s) or RS resource index(es) for the actual measurement for / of the one or more candidate / new beams. Optionally, the first (or last) half of the K configured / determined candidate RS(s) or RS resource(s) or RS resource index(es) or the half of the K configured / determined candidate RS(s) or RS resource(s) with the lowest (or highest) resource index(es) could be used / applied as the RS(s) or RS resource(s) or RS resource index(es) for the actual measurement for / of the one or more candidate / new beams. For instance, for a set of K=4 candidate RS resource indexes {RS index #1, RS index #2, RS index #3, RS index #4} configured / provided by the network (following those described / specified in the one or more explicit configurations described herein in the present disclosure), the RSs or RS resources corresponding / associated to the RS index #1 and RS index #2 in the set (i.e., the first half) could be used / applied as the RS(s) or RS resource(s) for the actual measurement for / of the one or more candidate / new beams.

[0295] n For another example, the even-ordered or even-numbered or even-indexed candidate RS(s) or RS resource(s) or RS resource index(es) or the candidate RS(s) or RS resource(s) with even-valued resource index(es) - among the K configured / determined candidate RS(s) or RS resource(s) or RS resource index(es) - could be used / applied as the RS(s) or RS resource(s) or RS resource index(es) for the actual measurement for / of the one or more candidate / new beams. For instance, for a set of K=4 candidate RS resource indexes {RS index #1, RS index #2, RS index #3, RS index #4} configured / provided by the network (following those described / specified in the one or more explicit configurations described herein in the present disclosure), the RSs or RS resources corresponding / associated to the RS index #2 and RS index #4 (even-valued RS resource indexes) in the set could be used / applied as the RS(s) or RS resource(s) for the actual measurement for / of the one or more candidate / new beams.

[0296] * For another example, the odd-ordered or odd-numbered or odd-indexed candidate RS(s) or RS resource(s) or RS resource index(es) or the candidate RS(s) or RS resource(s) with odd-valued resource index(es) - among the K configured / determined candidate RS(s) or RS resource(s) or RS resource index(es) - could be used / applied as the RS(s) or RS resource(s) or RS resource index(es) for the actual measurement for / of the one or more candidate / new beams. For instance, for a set of K=4 candidate RS resource indexes {RS index #1, RS index #2, RS index #3, RS index #4} configured / provided by the network (following those described / specified in the one or more explicit configurations described herein in the present disclosure), the RSs or RS resources corresponding / associated to the RS index #1 and RS index #3 (odd-valued RS resource indexes) in the set could be used / applied as the RS(s) or RS resource(s) for the actual measurement for / of the one or more candidate / new beams.

[0297] - In another example, the UE could indicate or transmit or send to the network, e.g., by / in part of a / the UEI beam report, one or more indicators to indicate which one or more of the candidate RS(s) or RS resource(s) or RS resource index(es) and / or the subset of the candidate RS(s) or RS resource(s) or RS resource index(es) to use / apply as the RS(s) or RS resource(s) or RS resource index(es) for the actual measurement for / of the one or more candidate / new beams.

[0298] * For example, the one or more indicators could be or could correspond to a set of RS resource index(es) - e.g., a set of CSI-RS resource configuration index(es) and / or SSB index(es). For this design example, each of the RS resource index(es) in the set could correspond / point to or represent a candidate RS / RS resource / RS resource index or one of the candidate RS(s) or RS resource(s) or RS resource index(es). In this case, the UE could determine / identify and / or indicate to the network that the candidate RS(s) or RS resource(s) or RS resource index(es) associated / corresponding to or pointed / represented by the RS resource index(es) in the set could be used / applied as the RS(s) or RS resource(s) or RS resource index(es) for the actual measurement for / of one or more candidate / new beams.

[0299] n For another example, the one or more indicators could be or could correspond to a bitmap with each entry / bit position of the bitmap corresponding / associated to a candidate RS / RS resource / RS resource index or one of the candidate RS(s) or RS resource(s) or RS resource index(es). In this case, when / if an entry / bit position of the bitmap is set to '1' (or '0'), the UE could determine / identify and / or indicate to the network that the candidate RS(s) or RS resource(s) or RS resource index(es) associated / corresponding to the entry / bit position could be used / applied as the RS(s) or RS resource(s) or RS resource index(es) for the actual measurement for / of one or more candidate / new beams. For instance, for a set of K 1 candidate RS resource indexes {RS index #1, RS index #2, ..., RS index #K} configured / provided by the network (e.g., the network 130) (following those described / specified in the one or more explicit configurations described herein in the present disclosure), the entries / bit positions in the bitmap associated / corresponding to the RS index #1, RS index #2 and RS index #K are set to '1's while the entry(s) / bit position(s) in the bitmap associated / corresponding to the RS index(es) other than the RS index #1, RS index #2 and RS index #K are set to '0's.

In this case, the RSs or RS resources corresponding / associated to the RS index #1, RS index #2 and RS index #K in the set corresponding / associated to the 1-bit indicators that are set to '1's could be used / applied as the RS(s) or RS resource(s) for the actual measurement for / of the one or more candidate / new beams.

[0301] As specified herein in the present disclosure, a UE could be indicated or configured or provided 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) according to or based on a corresponding UE's capability or capability signaling, one or more indicators to indicate which one or more of the candidate RS(s) or RS resource(s) or RS resource index(es) and / or the subset of the candidate RS(s) or RS resource(s) or RS resource index(es) to use / apply as the RS(s) or RS resource(s) or RS resource index(es) for the actual measurement for / of the one or more candidate / new beams. In particular, the one or more indicators as defined / specified herein in the present disclosure could be provided or indicated or contained or comprised or included or configured in a / the higher layer parameter TCI-State or TCI-UL-State that configures or provides the indicated TCI state.

[0302] - In one example, the one or more indicators could be or could correspond to a set of RS resource index(es) - e.g., a set of CSI-RS resource configuration index(es) and / or SSB index(es). As discussed / specified herein in the present disclosure, each of the RS resource index(es) in the set could correspond / point to or represent a candidate RS / RS resource / RS resource index or one of the candidate RS(s) or RS resource(s) or RS resource index(es). In this case, the UE could determine or identify that the candidate RS(s) or RS resource(s) or RS resource index(es) associated / corresponding to or pointed / represented by the RS resource index(es) in the set could be used / applied as the RS(s) or RS resource(s) or RS resource index(es) for the actual measurement for / of one or more candidate / new beams. For instance, for a set of K 1 candidate RS resource indexes {RS index #1, RS index #2, ..., RS index #K} configured / provided by the network (following those described / specified in the one or more explicit configurations described herein in the present disclosure), the one or more indicators (or equivalently, the set of RS resource index(es)) provided, indicated, contained, comprised, configured or included in a / the higher layer parameter TCI-State or TCI-UL-State that configures or provides the indicated TCI state could provide or indicate or contain or include or comprise one or more indexes each belonging to {1, ..., K}. Specifically, when / if the RS resource indexes in the set provided, indicated, contained, comprised, configured or included in a / the higher layer parameter TCI-State or TCI-UL-State that configures or provides the indicated TCI state correspond to {1, 2, K}, the RSs or RS resources corresponding / associated to the RS index #1, RS index #2 and RS index #K in the set could be used / applied as the RS(s) or RS resource(s) for the actual measurement for / of the one or more candidate / new beams.

[0303] - In another example, the one or more indicators could be or could correspond to a bitmap with each entry / bit position of the bitmap corresponding / associated to a candidate RS / RS resource / RS resource index or one of the candidate RS(s) or RS resource(s) or RS resource index(es). As discussed / specified herein in the present disclosure, when / if an entry / bit position of the bitmap is set to '1' (or '0'), the UE could determine or identify that the candidate RS(s) or RS resource(s) or RS resource index(es) associated / corresponding to the entry / bit position could be used / applied as the RS(s) or RS resource(s) or RS resource index(es) for the actual measurement for / of one or more candidate / new beams. For instance, for a set of K 1 candidate RS resource indexes {RS index #1, RS index #2, ..., RS index #K} configured / provided by the network (following those described / specified in the one or more explicit configurations described herein in the present disclosure), the entries / bit positions in the bitmap provided, indicated, contained, comprised, configured or indicated in a / the higher layer parameter TCI-State or TCI-UL-State that configures or provides the indicated TCI state associated / corresponding to the RS index #1, RS index #2 and RS index #K are set to '1's while the entry(s) / bit position(s) in the bitmap provided, indicated, contained, comprised, configured or indicated in a / the higher layer parameter TCI-State or TCI-UL-State that configures or provides the indicated TCI state associated / corresponding to the RS index(es) other than the RS index #1, RS index #2 and RS index #K are set to '0's. In this case, the RSs or RS resources corresponding / associated to the RS index #1, RS index #2 and RS index #K in the set corresponding / associated to the entries / bit positions in the bitmap provided, indicated, contained, comprised, configured or indicated in a / the higher layer parameter TCI-State or TCI-UL-State that configures or provides the indicated TCI state that are set to '1's could be used / applied as the RS(s) or RS resource(s) for the actual measurement for / of the one or more candidate / new beams.

[0304] - In another example, the one or more indicators could be or could correspond to one or more 1-bit indicators each corresponding / associated to a candidate RS / RS resource / RS resource index or one of the candidate RS(s) or RS resource(s) or RS resource index(es). As discussed / specified herein in the present disclosure, when / if a 1-bit indicator is set to '1' (or '0'), the UE (e.g., the UE 116) could determine or identify that the candidate RS(s) or RS resource(s) or RS resource index(es) associated / corresponding to the 1-bit indicator could be used / applied as the RS(s) or RS resource(s) or RS resource index(es) for the actual measurement for / of one or more candidate / new beams. For instance, for a set of K 1 candidate RS resource indexes {RS index #1, RS index #2, ..., RS index #K} configured / provided by the network (following those described / specified in the one or more explicit configurations described herein in the present disclosure), the 1-bit indicators provided, indicated, contained, comprised, configured or indicated in a / the higher layer parameter TCI-State or TCI-UL-State that configures or provides the indicated TCI state associated / corresponding to the RS index #1, RS index #2 and RS index #K are set to '1's while the 1-bit indicators provided, indicated, contained, comprised, configured or indicated in a / the higher layer parameter TCI-State or TCI-UL-State that configures or provides the indicated TCI state associated / corresponding to the RS index(es) other than the RS index #1, RS index #2 and RS index #K are set to '0's. In this case, the RSs or RS resources corresponding / associated to the RS index #1, RS index #2 and RS index #K in the set corresponding / associated to the 1-bit indicators provided, indicated, contained, comprised, configured or indicated in a / the higher layer parameter TCI-State or TCI-UL-State that configures or provides the indicated TCI state that are set to '1's could be used / applied as the RS(s) or RS resource(s) for the actual measurement for / of the one or more candidate / new beams.

[0305] For the described / specified design examples herein, when / if the higher layer parameter TCI-State or TCI-UL-State that configures or provides the indicated TCI state does not provide, contain, indicate, include, comprise or configure any of the one or more indicators as specified / defined herein in the present disclosure, and / or the one or more indicators as specified / defined herein in the present disclosure is absent or not present in the higher layer parameter TCI-State or TCI-UL-State that configures or provides the indicated TCI state, the UE could assess or evaluate the radio link / beam quality(s), e.g., by measuring the L1-RSRP(s) / L1-SINR(s), of the candidate RS(s) or RS resource(s) or RS resource index(es) configured following those specified / described in the one or more explicit configurations described herein and / or determined following those specified / described in the one or more implicit determination described herein to obtain the actual corresponding measurement result(s) for / of the one or more candidate / new beams.

[0306] Furthermore, the UE could first determine or identify, e.g., based on or according to (i) fixed rule(s) in system specification(s) or per RRC (re)configuration, (ii) 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) based on or according to a corresponding UE's capability or capability signaling, and / or (iii) UE's autonomous selection or determination, which could be further sent to the network via / in part of various UL channels / signals and / or CSI / beam report(s) and / or UE's capability signaling(s), one or more first candidate TCI states, wherein the first candidate TCI state(s) could be from a list of TCI state(s) higher layer configured or provided by the network, e.g., a list of joint / DL TCI state(s) provided by DLorJointTCI-State, and / or a set of TCI state(s) activated in / by a TCI state(s) activation / deactivation MAC CE command, and the (QCL source) RS(s) or RS resource(s) or RS resource index(es) provided in each of the first candidate TCI state(s) could correspond to a candidate candidate / new beam RS or RS resource or RS resource index as specified / defined herein in the present disclosure. Additionally, the UE could also determine or identify one or more of or a subset of the first candidate TCI state(s) as one or more second candidate TCI state(s) following or according to those specified or defined herein in the present disclosure for determining or identifying the actual candidate / new beam RS(s) / RS resource(s) / RS resource index(es) from the candidate candidate / new beam RS(s) / RS resource(s) / RS resource index(es) - including the indication(s) / configuration(s) / usage(s) / application(s) of the one or more indicators such as bitmap(s) / 1-bit indicator(s) / etc. as specified / defined herein in the present disclosure, wherein the (QCL source) RS(s) or RS resource(s) or RS resource index(es) provided in each of the second candidate TCI state(s) could correspond to an actual candidate / new beam RS or RS resource or RS resource index as defined / specified herein in the present disclosure.

[0307] As described or specified herein in the present disclosure, a RS or RS resource or RS resource index of / for a current serving beam - denoted by a current serving beam RS / RS resource / RS resource index - could be corresponding / associated / mapped to one or more of (or a subset of) candidate RSs or RS resources or RS resource indexes - denoted by candidate candidate / new beam RS(s) / RS resource(s) / RS resource index(es) - used / applied as the RS(s) or RS resource(s) or RS resource index(es) for actual measurement(s) of / for one or more candidate / new beams - denoted by actual candidate / new beam RS(s) / RS resource(s) / RS resource index(es), wherein the current serving beam RS / RS resource / RS resource index and / or the candidate or actual candidate / new beam RS(s) / RS resource(s) / RS resource index(es) could be configured and / or determined according to those specified herein in the present disclosure.

[0308] - In one example, the UE could be indicated or configured or provided 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) based on or according to a corresponding UE's capability or capability signaling, the correspondence(s) / association(s) / mapping(s) between a current serving beam RS / RS resource / RS resource index determined or configured or identified according to those specified / described herein in the present disclosure and one or more actual candidate / new beam RSs / RS resources / RS resource indexes (i.e., a subset of or one or more of candidate candidate / new beam RSs / RS resources / RS resource indexes) determined or configured or identified according to those specified / described herein in the present disclosure.

[0309] * For example, as described / specified herein in the present disclosure, the current serving beam RS / RS resource / RS resource index (or equivalently, the QCL source RS / RS resource / RS resource index) in the indicated TCI state provided by TCI-State or TCI-UL-State could be corresponding / associated / mapped to the actual candidate / new beam RS(s) / RS resource(s) / RS resource index(es) - i.e., a subset of or one or more of the candidate candidate / new beam RS(s) / RS resource(s) / RS resource index(es) following those specified herein in the present disclosure - provided, indicated, configured, comprised, included or contained in the same higher layer parameter(s) TCI-State or TCI-UL-State that provides or configures the indicated TCI state.

For this design example, the current serving beam RS / RS resource / RS resource index could be associated / mapped / corresponding to the one or more actual candidate / new beam RSs / RS resources / RS resource indexes.

[0311] * For another example, a / the higher layer RRC signaling(s) / parameter(s) and / or MAC CE command(s) and / or dynamic DCI based L1 signaling(s) that provides or configures or indicates one or more actual candidate / new beam RSs / RS resources / RS resource indexes and / or the one or more indicators as specified / defined herein in the present disclosure that point / correspond to or represent or indicate one or more actual candidate / new beam RSs / RS resources / RS resource indexes - i.e., a subset of or one or more of the candidate candidate / new beam RS(s) / RS resource(s) / RS resource index(es) following those specified herein in the present disclosure - could include, contain, provide, indicate, comprise or configure a current serving beam RS / RS resource / RS resource index.
