Description

Technical Field

[0001] This disclosure generally relates to wireless communication systems, and more specifically, to methods and apparatus for beam failure recovery within a unified TCI framework with multiple TRP operations. Background Technology

[0002] 5G mobile communication technology defines a wide frequency band, enabling high transmission rates and new services. It can be implemented not only in "sub-6GHz" bands such as 3.5GHz, but also in "above 6GHz" bands, including 28GHz and 39GHz, known as millimeter waves (mmWave). Furthermore, to achieve transmission rates 50 times faster than 5G and ultra-low latency one-tenth that of 5G, implementation of 6G mobile communication technology (referred to as "super 5G systems") in terahertz bands (e.g., the 95GHz to 3THz band) has been considered.

[0003] In the early stages of 5G mobile communication technology development, to support services and meet performance requirements related to enhanced mobile broadband (eMBB), ultra-reliable low-latency communication (URLLC), and massive machine-type communication (mMTC), standardization has been underway for the following: beamforming and massive MIMO to mitigate radio wave path loss and increase radio wave transmission distance in millimeter waves; support for parameter sets (e.g., operating multiple subcarrier spacings) for efficient utilization of millimeter wave resources and dynamic operation of time slot formats; initial access technologies to support multi-beam transmission and broadband; definition and operation of BWP (BandWidth Part); new channel coding methods, such as LDPC (Low Density Parity Check) codes for large data transmissions and polar codes for highly reliable transmission of control information; L2 preprocessing; and network slicing to provide dedicated networks for specific services.

[0004] Currently, given the services that 5G mobile communication technology will support, discussions are underway regarding improvements and performance enhancements to the initial 5G mobile communication technology, and physical layer standardization already exists for technologies such as: V2X (Vehicle-to-everything), used to assist autonomous vehicles in determining driving based on information sent by the vehicle about its location and status, and to enhance user convenience; NR-U (New Radio Unlicensed), for system operation in compliance with various regulatory requirements in unlicensed bands; NR UE power saving; Non-Terrestrial Network (NTN), which is UE-satellite direct communication used to provide coverage in areas where communication with terrestrial networks is unavailable; and positioning.

[0005] Furthermore, standardization is underway in air interface architecture / protocols for technologies such as: Industrial Internet of Things (IIoT) to support new services through interoperability and convergence with other industries; IAB (Integrated Access and Backhaul) to provide nodes for network service area extension by supporting radio backhaul and access links in an integrated manner; mobility enhancements, including conditional handover and DAPS (Dual Active Protocol Stack) handover; and two-step random access to simplify random access procedures (2-step RACH for NR). Standardization is also underway in system architecture / services for: 5G baseline architecture (e.g., service-based architecture or service-based interface) to combine Network Functions Virtualization (NFV) and Software-Defined Networking (SDN) technologies; and Mobile Edge Computing (MEC) for receiving services based on UE location.

[0006] With the commercialization of 5G mobile communication systems, the number of connected devices will increase exponentially, necessitating enhanced functionality and performance of 5G mobile communication systems and integrated operation of connected devices. To this end, new research is planned related to: Extended Reality (XR) for effectively supporting Augmented Reality (AR), Virtual Reality (VR), Mixed Reality (MR), etc.; improving 5G performance and reducing complexity by leveraging Artificial Intelligence (AI) and Machine Learning (ML); AI service support; Metaverse service support; and drone communication.

[0007] Furthermore, this development of 5G mobile communication systems will not only serve as the foundation for developing new waveforms for providing terahertz band coverage for 6G mobile communication technologies, multi-antenna transmission technologies (such as full-dimensional MIMO (FD-MIMO), array antennas, and massive MIMO), metamaterial-based lenses and antennas for improving terahertz band signal coverage, high-dimensional spatial multiplexing technologies using OAM (Orbital Angular Momentum), and RIS (Reconfigurable Intelligent Surface), but also as the foundation for developing full-duplex technologies to improve the frequency efficiency of 6G mobile communication technologies and improve system networks, AI-based communication technologies to implement system optimization by leveraging satellites and AI (Artificial Intelligence) from the design stage and internalizing end-to-end AI support capabilities, and next-generation distributed computing technologies to implement services with complexity levels exceeding the operational capabilities of UEs by utilizing ultra-high-performance communication and computing resources.

[0033] Wireless communication is already one of the most successful innovations in modern history. Recently, the number of subscribers to wireless communication services surpassed five billion and continues to grow rapidly. The demand for wireless data traffic is increasing rapidly due to the growing popularity of smartphones and other mobile data devices (such as tablets, notebook computers, netbooks, e-book readers, and machine-type devices) among consumers and businesses. To meet this high growth in mobile data traffic and support new applications and deployments, improvements in radio interface efficiency and coverage are crucial. To meet the increased demand for wireless data traffic since the deployment of 4G communication systems, and to enable various vertical applications, 5G communication systems have been developed and are currently being deployed.

[0034] The following discussion Figures 1 to 13 The various non-limiting embodiments used to describe the principles of this disclosure in this patent document are for illustrative purposes only and should not be construed as limiting the scope of this disclosure in any way. Those skilled in the art will understand that the principles of this disclosure can be implemented in any suitably arranged system or device.

[0035] To meet the increased demand for wireless data traffic since the deployment of 4G communication systems, and to enable various vertical applications, 5G / NR communication systems have been developed and are currently being deployed. 5G / NR communication systems are implemented in higher frequency (mmWave) bands (e.g., 28 GHz or 60 GHz) to achieve higher data rates, or in lower frequency bands (such as 6 GHz) to achieve robust coverage and mobility support. To reduce radio wave propagation loss and increase transmission distance, beamforming, massive MIMO, full-dimensional MIMO (FD-MIMO), array antennas, analog beamforming, and massive MIMO technologies are discussed in 5G / NR communication systems.

[0036] In addition, in 5G / NR communication systems, system network improvements are being developed based on advanced small cells, cloud radio access networks (RAN), ultra-dense networks, device-to-device (D2D) communication, wireless backhaul, mobile networks, cooperative communication, coordinated multipoint (CoMP), and receiver interference cancellation.

[0037] The discussion of 5G systems and their associated frequency bands is for informational purposes only, as one embodiment of this disclosure can be implemented in a 5G system. However, this disclosure is not limited to 5G systems or their associated frequency bands, and embodiments of this disclosure can be utilized in combination with any frequency band. For example, aspects of this disclosure can also be applied to the deployment of 5G communication systems, 6G, or even newer versions that may use terahertz (THz) bands.

[0038] The following documents and standards are hereby incorporated in this disclosure by reference, as if fully set forth herein: [1] 3GPP TS 38.211 v16.1.0, “NR; Physical Channels and Modulation;” [2] 3GPP TS 38.212 v16.1.0, “NR; Multiplexing and Channel Coding;” [3] 3GPP TS 38.213 v16.1.0, “NR; Physical Layer Specifications for Control;” [4] 3GPP TS 38.214 v16.1.0, “NR; Physical Layer Specifications for Data;” [5] 3GPP TS 38.321 v16.1.0, “NR; Media Access Control (MAC) Protocol Specification;” and [6] 3GPP TS 38.331 V16.1.0, “NR; Radio Resource Control (RRC) Protocol Specification.”

[0039] The following Figures 1 to 3 An embodiment implemented in a wireless communication system and implemented in conjunction with the use of orthogonal frequency division multiplexing (OFDM) or orthogonal frequency division multiple access (OFDMA) communication technologies is described. Figures 1 to 3 The description does not imply any physical or architectural limitations on how the different embodiments can be implemented. Different embodiments of this disclosure can be implemented in any suitably arranged communication system.

[0040] Figure 1 An example wireless network 100 according to an embodiment of the present disclosure is shown. Figure 1 The embodiment of the wireless network 100 shown is for illustrative purposes only. Other embodiments of the wireless network 100 may be used without departing from the scope of this disclosure.

[0041] like Figure 1 As shown, the wireless network 100 includes gNB 101 (e.g., a base station, BS), gNB 102, and gNB 103. gNB 101 communicates with gNB 102 and gNB 103. gNB 101 also communicates with at least one network 130 (such as the Internet, a proprietary Internet Protocol (IP) network, or other data network).

[0042] gNB 102 provides wireless broadband access to network 130 to a first plurality of user equipments (UEs) within its coverage area 120. The first plurality of UEs includes UE 111, which may be located in a small business; UE 112, which may be located in an enterprise; UE 113, which may be a WiFi hotspot; UE 114, which may be located in a first residence; UE 115, which may be located in a second residence; and UE 116, which may be a mobile device, such as a cellular phone, wireless laptop computer, wireless PDA, etc. gNB 103 provides wireless broadband access to network 130 to a second plurality of UEs within its coverage area 125. The second plurality of UEs includes UE 115 and UE 116. In an embodiment, one or more of gNBs 101-103 may communicate with each other and with UEs 111-116 using 5G / NR, Long Term Evolution (LTE), LTE-A Advanced, WiMAX, WiFi, or other wireless communication technologies.

[0043] Depending on the network type, the term "base station" or "BS" can refer to any component (or set of components) configured to provide wireless access to a network, such as a transmitting point (TP), a transmitting and receiving point (TRP), an enhanced base station (eNodeB or eNB), a 5G / NR base station (gNB), a macro cell, a femtocell, a WiFi access point (AP), or other wirelessly enabled device. The base station can provide wireless access according to one or more wireless communication protocols, such as 5G / NR 3rd Generation Partnership Project (3GPP) NR, Long Term Evolution (LTE), LTE-A Advanced (LTE-A), High Speed ​​Packet Access (HSPA), Wi-Fi 802.11a / b / g / n / ac, etc. For 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. Furthermore, depending on the network type, the term "user equipment" or "UE" can refer to any component such as a "mobile station," "subscriber station," "remote terminal," "wireless terminal," "receiving point," or "user device." For convenience, the terms “user equipment” and “UE” are used in this patent document to refer to a remote wireless device for wireless access to a BS, whether the UE is a mobile device (such as a mobile phone or smartphone) or is generally considered to be a fixed device (such as a desktop computer or vending machine).

[0044] The dashed lines indicate the approximate extent of coverage areas 120 and 125, which are shown as approximately circular for illustrative and explanatory purposes only. It should be clearly understood that coverage areas associated with the gNB (such as coverage areas 120 and 125) may have other shapes, including irregular shapes, depending on the configuration of the gNB and variations in the radio environment associated with natural and man-made obstacles.

[0045] As described in more detail below, one or more of UEs 111-116 include circuitry, programming, or a combination thereof for performing beam failure recovery within a unified TCI framework with multiple TRP operations. In one embodiment, one or more of BSs 101-103 include circuitry, programming, or a combination thereof for supporting beam failure recovery within a unified TCI framework with multiple TRP operations.

[0046] although Figure 1 An example of a wireless network is shown, but more can be found on... Figure 1 Various modifications can be made. For example, wireless network 100 can include any number of gNBs and any number of UEs in any suitable arrangement. Furthermore, gNB 101 can communicate directly with any number of UEs and provide these UEs with wireless broadband access to network 130. Similarly, each gNB 102-103 can communicate directly with network 130 and provide UEs with direct wireless broadband access to network 130. Additionally, gNBs 101, 102, and / or 103 can provide access to other or additional external networks, such as external telephone networks or other types of data networks.

[0047] Figure 2 An example gNB 102 according to an embodiment of the present disclosure is shown. Figure 2 The embodiment of gNB 102 shown is for illustrative purposes only, and Figure 1 gNBs 101 and 103 can have the same or similar configurations. However, gNBs have a wide variety of configurations, and Figure 2 This disclosure is not intended to limit the scope of any particular implementation of gNB.

[0048] like Figure 2 As shown, 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.

[0049] Transceivers 210a-210n receive incoming radio frequency (RF) signals from antennas 205a-205n, such as signals transmitted by a UE in wireless network 100. 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 transceivers 210a-210n and / or controller / processor 225, which generates processed baseband signals by filtering, decoding, and / or digitizing the baseband or IF signals. Controller / processor 225 can further process the baseband signals.

[0050] The transmit (TX) processing circuitry in transceivers 210a-210n and / or controller / processor 225 receives analog or digital data (such as voice data, web data, email, or interactive video game data) from controller / processor 225. The TX processing circuitry encodes, multiplexes, and / or digitizes the outgoing baseband data to generate a processed baseband or IF signal. Transceivers 210a-210n up-convert the baseband or IF signal into an RF signal transmitted via antennas 205a-205n.

[0051] The controller / processor 225 may include one or more processors or other processing devices that control the overall operation of the gNB 102. For example, the controller / processor 225 may control the transceivers 210a-210n to receive uplink (UL) channel signals and transmit downlink (DL) channel signals according to well-known principles. The controller / processor 225 may also support additional functions, such as more advanced wireless communication functions. For example, the controller / processor 225 may support beamforming or directional routing operations, wherein outgoing / incoming signals from / to multiple antennas 205a-205n are weighted differently to effectively guide outgoing signals to a desired direction. The controller / processor 225 may support any of a variety of other functions in the gNB 102.

[0052] The controller / processor 225 is also capable of executing programs and other processes residing in memory 230, such as supporting beam failure recovery under a unified TCI framework with multiple TRP operations. The controller / processor 225 can move data into or out of memory 230 as needed during execution.

[0053] The controller / processor 225 is also coupled to a backhaul or network interface 235. The backhaul or network interface 235 allows the gNB 102 to communicate with other devices or systems via a backhaul connection or over a network. Interface 235 can support communication via any suitable wired or wireless connection. For example, when the gNB 102 is implemented as part of a cellular communication system (such as a cellular communication system supporting 5G / NR, LTE, or LTE-A), interface 235 can allow the gNB 102 to communicate with other gNBs via a wired or wireless backhaul connection. When the gNB 102 is implemented as an access point, interface 235 can allow the gNB 102 to communicate via a wired or wireless local area network or via a wired or wireless connection to a larger network (such as the Internet). Interface 235 includes any suitable architecture supporting communication via a wired or wireless connection, such as Ethernet or a transceiver.

[0054] Memory 230 is coupled to controller / processor 225. A portion of memory 230 may include RAM, and another portion of memory 230 may include flash memory or other ROM.

[0055] although Figure 2 An example of gNB 102 is shown, but it is possible to compare it with other models. Figure 2 Various changes can be made. For example, gNB 102 can include any number of Figure 2 Each component shown. Furthermore, depending on specific needs, Figure 2 The various components can be combined, further subdivided, or omitted, and additional components can be added.

[0056] Figure 3 An example UE 116 according to an embodiment of the present disclosure is shown. Figure 3 The embodiment of UE 116 shown is for illustrative purposes only, and Figure 1 UEs 111-115 can have the same or similar configurations. However, UEs have a wide variety of configurations, and Figure 3 This disclosure is not intended to limit the scope of any particular implementation of the UE.

[0057] like Figure 3 As shown, UE 116 includes an antenna 305, a transceiver 310, and a microphone 320. 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 memory 360. Memory 360 includes an operating system (OS) 361 and one or more applications 362.

[0058] Transceiver 310 receives incoming RF signals transmitted by a gNB of wireless network 100 from antenna 305. Transceiver 310 down-converts the incoming RF signals to generate intermediate frequency (IF) or baseband signals. The IF or baseband signals are processed by RX processing circuitry in transceiver 310 and / or processor 340, which generates processed baseband signals by filtering, decoding, and / or digitizing the baseband or IF signals. The RX processing circuitry sends the processed baseband signals to speaker 330 (e.g., for voice data) or to processor 340 (e.g., for web browsing data).

[0059] The TX processing circuitry in transceiver 310 and / or processor 340 receives analog or digital voice data from microphone 320 or other outgoing baseband data (such as web data, email, or interactive video game data) from processor 340. The TX processing circuitry encodes, multiplexes, and / or digitizes the outgoing baseband data to generate a processed baseband or IF signal. Transceiver 310 up-converts the baseband or IF signal into an RF signal transmitted via antenna 305.

[0060] Processor 340 may include one or more processors or other processing devices and executes OS 361 stored in memory 360 to control the overall operation of UE 116. For example, processor 340 may control transceiver 310 to receive DL channel signals and transmit UL channel signals according to well-known principles. In embodiments, processor 340 includes at least one microprocessor or microcontroller.

[0061] Processor 340 is also capable of executing other processes and programs residing in memory 360. For example, processor 340 may execute processes to utilize and / or identify beam failure recovery under a unified TCI framework with multiple TRP operations, as described in embodiments of this disclosure. Processor 340 may move data into or out of memory 360 as needed for the execution process. In embodiments, processor 340 is configured to execute application 362 based on OS 361 or in response to signals received from gNB or operator. Processor 340 is also coupled to I / O interface 345, which provides UE 116 with the ability to connect to other devices, such as laptop computers and handheld computers. I / O interface 345 is the communication path between these accessories and processor 340.

[0062] The processor 340 is also coupled to an input 350 and a display 355. The input 350 includes, for example, a touchscreen, a keypad, etc. The operator of the UE 116 can use the input 350 to input data into the UE 116. The display 355 may be a liquid crystal display, a light-emitting diode display, or other display capable of rendering text and / or at least limited graphics (such as from a website).

[0063] The memory 360 is coupled to the processor 340. A portion of the memory 360 may include random access memory (RAM), and another portion of the memory 360 may include flash memory or other read-only memory (ROM).

[0064] although Figure 3 An example of UE 116 is shown, but it is possible to modify it. Figure 3 Make various changes. For example, according to specific needs, Figure 3 The various components can be combined, further subdivided, or omitted, and additional components can be added. As a specific example, processor 340 can 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, transceiver 310 can include any number of transceivers and signal processing chains and can be connected to any number of antennas. Furthermore, although... Figure 3 The UE 116 is shown configured as a mobile phone or smartphone, but the UE can be configured to operate as other types of mobile or fixed devices.

[0065] Figure 4A and Figure 4B Examples of a wireless transmit path 400 and a wireless receive path 450 according to embodiments of the present disclosure are shown respectively. For example, transmit path 400 may be described as being implemented in a gNB (such as gNB 102), while receive path 450 may be described as being implemented in a UE (such as UE 116). However, it will be understood that receive path 450 may be implemented in a gNB, and transmit path 400 may be implemented in a UE. In embodiments, transmit path 400 and / or receive path 450 are configured to support beam failure recovery under a unified TCI framework with multiple TRP operations as described in embodiments of the present disclosure.

[0066] like Figure 4A As shown, the transmit path 400 includes a channel coding and modulation block 205, a serial-to-parallel (S to P) block 410, an N-size inverse fast Fourier transform (IFFT) block 415, a parallel-to-serial (P to S) block 420, a cyclic prefix addition block 425, and an up-converter (UC) 430. The receive path 250 includes a down-converter (DC) 455, a cyclic prefix removal block 460, an S to P block 465, an N-size fast Fourier transform (FFT) block 470, a parallel-to-serial (P to S) block 475, and a channel decoding and demodulation block 480.

[0067] In transmit path 400, channel coding and modulation block 405 receives a set of information bits, applies coding (such as low-density parity-check (LDPC) coding), and modulates the input bits (such as using quadrature phase shift keying (QPSK) or quadrature amplitude modulation (QAM)) to generate a sequence of frequency-domain modulated symbols. Serial-to-parallel block 410 converts (such as demultiplexes) the serial modulated symbols into parallel data to generate N parallel symbol streams, where N is the IFFT / FFT size used in gNB 102 and UE 116. IFFT block 415 of size N performs an IFFT operation on the N parallel symbol streams to generate a time-domain output signal. Parallel-to-serial block 420 converts (such as multiplexes) the parallel time-domain output symbols from IFFT block 415 of size N to generate a serial time-domain signal. Cyclic prefix addition block 425 inserts a cyclic prefix into the time-domain signal. Upconverter 430 modulates (such as upconverts) the output of cyclic prefix addition block 425 to an RF frequency for transmission via the wireless channel. The signal can also be filtered at the baseband before being switched to the RF frequency.

[0068] like Figure 4B As shown, downconverter 455 downconverts the received signal to the baseband frequency, and cyclic prefix removal block 460 removes the cyclic prefix to generate a serial time-domain baseband signal. Serial-to-parallel block 465 converts the time-domain baseband signal into a parallel time-domain signal. FFT block 470 of size N performs an FFT algorithm to generate N parallel frequency-domain signals. (P to S) block 475 converts the parallel frequency-domain signals into a sequence of modulated data symbols. Channel decoding and demodulation block 480 demodulates and decodes the modulated symbols to recover the original input data stream.

[0069] Each of gNBs 101-103 can implement a transmission path 400 similar to that sent to UEs 111-116 in the downlink, and can implement a reception path 450 similar to that received from UEs 111-116 in the uplink. Similarly, each of UEs 111-116 can implement a transmission path 400 for sending to gNBs 101-103 in the uplink, and can implement a reception path 450 for receiving from gNBs 101-103 in the downlink.

[0070] Figure 4A and Figure 4B Each component can be implemented using only hardware or a combination of hardware and software / firmware. As a specific example, Figure 4A and Figure 4BAt least some components can be implemented in software, while others can be implemented in configurable hardware or a hybrid of software and configurable hardware. For example, FFT block 470 and IFFT block 415 can be implemented as configurable software algorithms, wherein the value of size N can be modified according to the implementation method.

[0071] Furthermore, although described as using FFT and IFFT, this is merely illustrative and should not be construed as limiting the scope of this disclosure. Other types of transforms, such as the Discrete Fourier Transform (DFT) and Inverse Discrete Fourier Transform (IDFT) functions, may be used. It will be understood that for the DFT and IDFT functions, the value of the variable N can be any integer (such as 1, 2, 3, 4, etc.), while for the FFT and IFFT functions, the value of the variable N can be any integer that is a power of 2 (such as 1, 2, 4, 8, 16, etc.).

[0072] although Figure 4A and Figure 4B Examples of wireless transmission path 400 and wireless reception path 450 are shown respectively, but it is possible to... Figure 4A and Figure 4B Various changes can be made. For example, depending on specific needs, it can be combined, further subdivided, or omitted. Figure 4A and Figure 4B It contains various components, and additional components can be added. Furthermore, Figure 4A and Figure 4B This is intended to illustrate examples of the types of transmit and receive paths that can be used in a wireless network. Any other suitable architecture can be used to support wireless communication in a wireless network.

[0073] like Figure 5A As shown, in the wireless system 500, the beam 501 of device 504 can be characterized by beam direction 502 and beamwidth 503. For example, device 504 (or UE 116) transmits RF energy in the beam direction and within the beamwidth. Device 504 receives RF energy in the beam direction and within the beamwidth. Figure 5A As shown, since point A is within the beamwidth and direction of the beam from device 504, the device at point A 505 can receive from and transmit to device 504. Figure 5A As shown, the device at point B 506 cannot receive from or transmit to device 504 because point B 506 is outside the beamwidth and direction of the beam from device 504. Although for illustrative purposes, Figure 5A A 2D beam is shown, but it will be apparent to those skilled in the art that the beam can be 3D, where the beam direction and beamwidth are defined in space.

[0074] Figure 5B An example of multi-beam operation 550 according to an embodiment of the present disclosure is shown. For example, multi-beam operation 550 may be... Figure 3 The UE 116 is utilized. This example is for illustration only, and other embodiments may be used without departing from the scope of this disclosure.

[0075] In wireless systems, devices can transmit and / or receive on multiple beams. This is known as "multi-beam operation." (Although for illustrative purposes...) Figure 5B The beam in the image is 2D, but it will be apparent to those skilled in the art that the beam can be 3D, wherein the beam can be sent to or received from any direction in space.

[0076] Figure 6 An example of a transmitter structure 600 for beamforming according to an embodiment of the present disclosure is shown. In one embodiment, one or more of gNB 102 or UE 116 include transmitter structure 600. For example, antenna 205 and its associated system or antenna 305 and its associated system, one or more of these may be included in transmitter structure 600. This example is for illustration only, and other embodiments may be used without departing from the scope of the present disclosure.

[0077] Therefore, embodiments of this disclosure recognize that Rel-14 LTE and Rel-15 NR support up to 32 Channel State Information Reference Signal (CSI-RS) antenna ports, enabling eNBs or gNBs to be equipped with a large number of antenna elements (such as 64 or 128). Multiple antenna elements can then be mapped onto a single CSI-RS port. For millimeter-wave bands, although the number of antenna elements can be greater for a given form factor, hardware constraints (such as the feasibility of mounting a large number of analog-to-digital converters (ADCs) / digital-to-analog converters (DACs) at millimeter-wave frequencies) can limit the number of CSI-RS ports that can correspond to the number of digital precoding ports, such as... Figure 6 As shown. A CSI-RS port can then be mapped to a large number of antenna elements that can be controlled by a set of analog phase shifters 601. A CSI-RS port can then correspond to a subarray that generates a narrow analog beam through analog beamforming 605. This analog beam can be configured to sweep across a wider range of angles 620 by changing the phase shifter group across symbols or slots / subframes. The number of subarrays (equal to the number of RF chains) is related to the number of CSI-RS ports N. CSI-PORT Same. Digital beamforming unit 610 spans N CSI-PORTThe analog beams are linearly combined to further increase the precoding gain. While the analog beams are broadband (and therefore not frequency-selective), the digital precoding can vary across frequency subbands or resource blocks. Receiver operation can be envisioned similarly.

[0078] because Figure 6 The transmitter structure 600 utilizes multiple analog beams for transmission and reception (where, for example, one or a few analog beams are selected from a large number of analog beams after a training duration performed occasionally or periodically), hence the term "multi-beam operation" is used to refer to this aspect of the entire system. For illustrative purposes, this includes indicating the assigned DL or UL TX beam (also referred to as "beam indication"), measuring at least one reference signal for calculating and performing beam reporting (also referred to as "beam measurement" and "beam reporting," respectively), and receiving DL or UL transmissions via selecting the corresponding RX beam. Figure 6 The system is also suitable for higher frequency bands, such as >52.6 GHz (also known as frequency range 4 or FR4). In this case, the system can use only analog beams. Due to O2 absorption loss near 60 GHz (an additional loss of ~10 dB per 100 m distance), a larger number and narrower analog beams (and therefore a larger number of radiators in the array) are needed to compensate for the additional path loss.

[0079] The text and accompanying drawings are provided by way of example only to aid the reader in understanding this disclosure. They are not intended and should not be construed as limiting the scope of this disclosure in any way. Although certain embodiments and examples have been provided, it will be apparent to those skilled in the art, based on the disclosure herein, that changes can be made to the illustrated embodiments and examples without departing from the scope of this disclosure. The transmitter structure 600 for beamforming is for illustrative purposes only, and other embodiments may be used without departing from the scope of this disclosure.

[0080] Although the accompanying drawings illustrate different examples of user equipment, various changes can be made to the drawings. For example, the user equipment can include any number of each component in any suitable arrangement. Generally, the drawings do not limit the scope of this disclosure to any particular configuration. Furthermore, while the drawings illustrate operating 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.

[0081] Any of the above variant embodiments can be used independently or in combination with at least one other variant embodiment.

[0082] Although this disclosure has been described using exemplary embodiments, various changes and modifications may be suggested to those skilled in the art. This disclosure is intended to cover such changes and modifications that fall within the scope of the appended claims. Nothing described herein should be construed as implying that any particular element, step, or function is an essential element that must be included within the scope of the claims. The scope of the subject matter is defined by the claims.

[0083] In embodiments of this disclosure, a beam is determined by either a Transmission Configuration Indicator (TCI) state that establishes a quasi-co-location (QCL) relationship between a source reference signal (RS) (e.g., a single-sideband (SSB) and / or a channel state information reference signal (CSI-RS)) and a target RS, or by establishing spatial relationship information associated with a source RS (such as an SSB, CSI-RS, or a probe reference signal (SRS)). In either case, the ID of the source reference signal identifies the beam. The TCI state and / or the spatial relationship reference RS can determine a spatial RX filter for receiving downlink channels at UE 116, or a spatial TX filter for transmitting uplink channels from UE 116.

[0084] In this disclosure, the beam is determined by any of the following:

[0085] - TCI states that establish a quasi-co-address (QCL) relationship between a source reference signal (e.g., SSB and / or CSI-RS) and a target reference signal.

[0086] - Establish spatial relationship information associated with the source reference signal (such as SSB, CSI-RS, or SRS).

[0087] In either case, the ID of the source reference signal identifies the beam.

[0088] The TCI status and / or spatial relationship reference RS can determine the spatial Rx filter used to receive downlink channels at the UE, or the spatial TX filter used to transmit uplink channels from the UE.

[0089] Figure 7 An example system 700 for multiple TRPs according to embodiments of the present disclosure is shown. For example, system 700 can... Figure 1 This example illustrates the operation within the wireless network 100. This example is for illustrative purposes only, and other embodiments may be used without departing from the scope of this disclosure.

[0090] refer to Figure 7The UE can simultaneously receive various channels / RS, such as the Physical Downlink Control Channel (PDCCH) and / or Physical Downlink Shared Channel (PDSCH), from multiple physically non-co-located TRPs using a single receive (RX) panel or multiple RX panels. In this disclosure, an RX panel may correspond to a set of RX antenna elements / ports, a set of measurement RS resources (such as SRS resources), spatial domain RX filters, etc., at the UE 116. Furthermore, a TRP in a multi-TRP system may represent a set of measurement antenna ports, measurement RS resources, and / or control resource sets (CORESET). For example, a TRP may be associated with one or more of the following:

[0091] - Multiple CSI-RS resources

[0092] - Multiple CRIs (CSI-RS Resource Indexes / Indicators)

[0093] -Measure RS resource sets, such as CSI-RS resource sets and their indicators.

[0094] - Multiple CORESETs associated with CORESETPoolIndex

[0095] - Multiple CORESETs associated with a TRP-specific index / indicator / identifier

[0096] A cell / TRP can be a non-serving cell / TRP. In this disclosure, a non-serving cell or non-serving cell TRP may have / broadcast a PCI and / or other higher-layer signaling index values ​​different from the physical cell ID (PCI) (i.e., the serving cell PCI) of the serving cell or serving cell TRP. In one example, the serving cell or serving cell TRP may be associated with a serving cell ID (SCI) and / or a serving cell PCI. That is, for inter-cell operations evaluated in this disclosure, different cell / TRPs may broadcast different PCIs, and / or one or more cell / TRPs (referred to / defined as non-serving cell / TRPs in this disclosure) may broadcast a PCI different from the PCI (i.e., the serving cell PCI) of the serving cell / TRP, and / or one or more cell / TRPs are not associated with a valid SCI (e.g., provided by the higher-layer parameter ServCellIndex). In this disclosure, a non-serving cell PCI may also be referred to as an additional PCI, another PCI, or a different PCI (relative to the serving cell PCI).

[0097] Furthermore, in wireless communication systems, a radio link failure (RLF) may occur if a significant / sudden degradation of link quality is observed at the UE side. Embodiments of this disclosure recognize that, in the event of an RLF, a fast RLF recovery mechanism becomes essential for rapidly re-establishing the communication link and avoiding severe service interruptions. At higher frequencies, such as millimeter wave (mmWave) frequencies or FR2 in 3GPP NR, both transmitters and receivers can use directional (analog) beams to transmit and receive various RS / channels, such as SSB, CSI-RS, PDCCH, or PDSCH. Therefore, before declaring a full RLF, if the signal quality / strength of some beamp-to-link (BPL) falls below a certain threshold for a period of time, the UE can first detect and recover from the beam failure.

[0098] Figure 8 An example PCell system 800 according to an embodiment of the present disclosure is shown. For example, system 800 can... Figure 1 This example illustrates the operation within the wireless network 100. This example is for illustrative purposes only, and other embodiments may be used without departing from the scope of this disclosure.

[0099] The 3GPP Rel.15 Beam Failure Recovery (BFR) procedure is primarily for primary cells (PCell or PSCell) under the Carrier Aggregation (CA) framework. Figure 8 The BFR specification in 3GPP Rel.15 includes the following key components:

[0100] - Beam Failure Detection (BFD)

[0101] - New Beam Identification (NBI)

[0102] -BFR Request (BFRQ)

[0103] -BFRQ response (BFRR)

[0104] The UE is first configured by the gNB (e.g., gNB 102) with a set of BFD RS resources to monitor the link quality between the gNB and the UE. One BFD RS resource can correspond to a (periodic) CSI-RS / SSB RS resource, which can be a quasi-co-located (QCL) source RS in the CORESET TCI state. If the received signal quality of the BFD RS resource is below a given threshold (meaning the hypothetical block error rate (BLER) of the corresponding CORESET / PDCCH is above a given threshold), the UE can declare a beam failure instance (BFI). Furthermore, if the UE has declared N_BFI consecutive BFIs within a given time period, the UE will declare a beam failure.

[0105] Upon claiming / detecting a beam failure, the UE will transmit a BFRQ to the gNB via a contention-free (CF) PRACH (CF BFR-PRACH) resource, the index of which is associated with a new beam identified by the UE. Specifically, to determine the new beam, the UE can first have a set of SSB and / or CSI-RS resources (NBI RS resources) configured by the network via the higher-layer parameter candidateBeamRSList. The UE will then measure the NBI RSs and calculate their Layer 1 Reference Signal Received Power (L1-RSRP). If at least one of the measured L1-RSRPs of an NBI RS exceeds a given threshold, the UE will select the beam corresponding to the NBI RS with the highest L1-RSRP as the new beam q_new. To determine the CF BFR-PRACH resource used to transmit the BFRQ, the UE can first have a set of PRACH resources configured by the network, each PRACH resource associated with an NBI RS resource. The UE can then select a PRACH resource that has a one-to-one correspondence with the selected NBI RS resource (and therefore, the new beam index q_new) to send the BFRQ to the gNB. Based on the index of the selected CF PRACH resource, the gNB can also determine which beam the UE has selected as the new beam.

[0106] Four time slots after the UE has sent the BFRQ, the UE can begin monitoring a dedicated CORESET / search space for BFRQ responses. The dedicated CORESET is addressed to the UE-specific cell radio network temporary identifier (C-RNTI) and will be transmitted by the gNB using a newly identified beam. If the UE detects valid UE-specific downlink control information (DCI) in the dedicated CORESET used for the BFRQ, the UE anticipates that the beam failure recovery request has been successfully received by the network, and the UE will complete the BFR procedure. Otherwise, if the UE does not receive the BFRR within the configured time window, the UE will initiate a contention-based (CB) random access (RA) procedure to reconnect to the network.

[0107] Figure 9 An example system 900 of a secondary cell (SCell) according to an embodiment of the present disclosure is shown. For example, system 900 can... Figure 1 This example illustrates the operation within the wireless network 100. This example is for illustrative purposes only, and other embodiments may be used without departing from the scope of this disclosure.

[0108] In 3GPP Rel.16, BFR procedures are customized for secondary cells (SCells) under the CA framework, where BPL between the PCell and UE is expected to be operational. (Reference) Figure 9An illustrative example of SCell beam failure is given.

[0109] After declaring / detecting a beam failure in an SCell, the UE will send a BFRQ in the form of a Scheduling Request (SR) via the Physical Uplink Control Channel (PUCCH) for the working PCell. Furthermore, the UE can send the BFRQ only at this stage without indicating any new beam index, failed SCell index, or other information to the network. This differs from the Rel.15 PCell / PSCell protocol, where the UE indicates both the BFRQ and the identified new beam index to the network simultaneously. Allowing the gNB to quickly know the beam failure status of an SCell without waiting for the UE to identify a new beam can be beneficial. For example, the gNB could disable the failed SCell and allocate resources to other working SCells.

[0110] The network (e.g., network 130) may, in response to a BFRQ SR, indicate an uplink grant to the UE that allocates the necessary resources for the MAC CE to carry a new beam index q_new (if identified), a failed SCell index, etc., on the Physical Uplink Shared Channel (PUSCH) of the working PCell. After sending the MAC CE for BFR to the working PCell, the UE will begin monitoring the BFRR. The BFRR may be a TCI status indication for the corresponding SCell's CORESET. The BFRR to the MAC CE for BFR may also be a normal uplink grant for scheduling a new transmission using the same Hybrid Automatic Repeat Request (HARQ) procedure as the PUSCH carrying the MAC CE for BFR. If the UE fails to receive the BFRQ within the configured time window, the UE may resend the BFR-PUCCH or fall back to the CBRA procedure.

[0111] This disclosure provides various design aspects relating to the transmission of beam failure recovery requests (BFRQs) and information related to beams with radio link quality below a threshold in a multi-TRP system, wherein beam / TRP selection is performed within a unified TCI framework.

[0112] As specified in Rel-17, the unified TCI framework may indicate / include N ≥ 1 DL TCI states and / or M ≥ 1 UL TCI states, wherein the indicated TCI state may be at least one of the following:

[0113] -DL TCI status and / or its corresponding / associated TCI status ID

[0114] -UL TCI status and / or its corresponding / associated TCI status ID

[0115] - Combine DL and UL TCI status and / or its corresponding / associated TCI status ID

[0116] - Individual DL TCI status and UL TCI status and / or their corresponding / associated TCI status ID

[0117] Various design options / channels can exist to indicate to the UE the beams (i.e., TCI states) used for PDCCH or PDSCH transmission / reception. As described in 3GPP Rel-17,

[0118] - In one example, the MAC CE can be used to indicate to the UE the beam used for transmitting / receiving PDCCH or PDSCH (i.e., TCI status and / or TCI status ID).

[0119] - In another example, DCI can be used to indicate to the UE the beam used for transmitting / receiving PDCCH or PDSCH (i.e., TCI status and / or TCI status ID).

[0120] For example, DL-related DCI (e.g., DCI format 1_0, DCI format 1_1, or DCI format 1_2) can be used to indicate to the UE the beam for transmission / reception of PDCCH or PDSCH (i.e., TCI status and / or TCI status ID), wherein DL-related DCI may or may not include DL assignment.

[0121] For example, UL-related DCIs (e.g., DCI format 0_0, DCI format 0_1, DCI format 0_2) can be used to indicate to the UE the beams for transmitting / receiving PDCCH or PDSCH (i.e., TCI status and / or TCI status ID), wherein the UL-related DCIs may or may not include UL scheduling authorization.

[0122] For example, a custom / purpose-designed DCI format can be used to indicate to the UE the beams for transmitting / receiving PDCCH or PDSCH (i.e., TCI status and / or TCI status ID).

[0123] Rel-17 introduced a unified TCI framework, in which the unified, primary, or major TCI status is signaled to the UE. The unified, primary, or major TCI status can be one of the following:

[0124] - In the case of a joint TCI status indication, where the same beam is used for the DL and UL channels, the joint TCI status can be used for at least the UE-dedicated DL channel and the UE-dedicated UL channel.

[0125] - In the case of separate TCI status indication, where different beams are used for DL ​​and UL channels, the DL TCI status can be used at least for the UE-dedicated DL channel.

[0126] - In the case of separate TCI status indication, where different beams are used for DL ​​and UL channels, the UL TCI status can be used at least for the UE-dedicated UL channel.

[0127] The unified (primary or main) TCI status is the TCI status of UE-dedicated reception on PDSCH / PDCCH or PUSCH and dedicated PUCCH resources based on dynamic authorization / configuration authorization.

[0128] The UE can receive a first (unified) TCI state activation MAC CE command and / or a second (unified) TCI state activation MAC CE command from the network. The first (unified) TCI state activation MAC CE command is used to map up to 8 TCI states and / or TCI state pairs to a code point of the DCI field "Transmission Configuration Indication" of one or a set of CC / DL bandwidth portions (BWPs), wherein each pair includes one TCI state for DL ​​channel / signal and / or one TCI state for UL channel / signal. The second (unified) TCI state activation MAC CE command is used to map up to 8 sets of TCI states to one or a set of CC / DL BWPs and, if applicable, a code point of the DCI field "Transmission Configuration Indication" of one or a set of CC / UL BWPs, wherein each set may include up to two (e.g., none, one or two) TCI states for DL ​​and UL signals / channels, and / or up to two (e.g., none, one or two) TCI states for DL ​​channel / signal and / or up to two (e.g., none, one or two) TCI states for UL channel / signal. When a set of CC / DL BWPs is activated, and if applicable, a set of TCI state IDs are activated for a set of CC / UL BWPs, where the applicable list of CCs is determined by the CCs indicated in the activation command, the same set of TCI state IDs is applied to the DL and / or UL BWPs in the indicated CCs. If the first / second MAC CE activation command maps TCI-State and / or TCI-UL-State to only one TCI code point, once the indicated mapping for a single TCI code point is applied, the UE should apply the indicated TCI-State and / or TCI-UL-State to one or a set of CC / DL BWPs, and if applicable, one or a set of CC / UL BWPs. In other words, for example, when the UE is provided / configured with dl-OrJointTCI-StateList and / or ul-TCI-StateList and / or has one or two indicated TCI states and / or has a first and / or a second indicated TCI state, the activated TCI code point in the second MAC CE activation command can consist of / include one of the following:

[0129] Case 1: First TCI state for DL ​​channel / signal

[0130] - Case 2: First TCI state for DL ​​channel / signal and second TCI state for DL ​​channel / signal

[0131] -Scenario 3: First TCI state for DL ​​channel / signal and second TCI state for UL channel / signal

[0132] Case 4: A first TCI state for the DL channel / signal and a pair of second TCI states for the DL channel / signal and a second TCI state for the UL channel / signal.

[0133] - Case 5: First TCI state for UL channel / signal

[0134] - Case 6: First TCI state for UL channel / signal and second TCI state for DL ​​channel / signal

[0135] - Case 7: First TCI state for UL channel / signal and second TCI state for UL channel / signal

[0136] Case 8: A first TCI state for the UL channel / signal and a pair of second TCI states for the DL channel / signal and a second TCI state for the UL channel / signal.

[0137] Case 9: A pair of first TCI states for DL ​​channel / signal and first TCI states for UL channel / signal

[0138] - Case 10: A pair of first TCI states for DL ​​channel / signal and first TCI states for UL channel / signal, and a second TCI state for DL ​​channel / signal.

[0139] Case 11: A pair of first TCI states for DL ​​channel / signal and first TCI states for UL channel / signal, and a second TCI state for UL channel / signal.

[0140] Case 12: A pair of first TCI states for DL ​​channel / signal and a pair of second TCI states for UL channel / signal, and a pair of second TCI states for DL ​​channel / signal and a pair of second TCI states for UL channel / signal.

[0141] -Case 13: Second TCI state for DL ​​channel / signal

[0142] -Case 14: Second TCI State for UL Channel / Signal

[0143] -Case 15: A pair of second TCI states for DL ​​channel / signal and a pair of second TCI states for UL channel / signal

[0144] -Case 16: First TCI state for DL ​​channel / signal and UL channel / signal

[0145] - Case 17: Second TCI state for DL ​​channel / signal and UL channel / signal

[0146] -Case 18: A pair of first TCI states for DL ​​channel / signal and UL channel / signal and a second TCI state for DL ​​channel / signal and UL channel / signal.

[0147] Furthermore, when the UE is configured by a higher-level parameter PDCCH-Config containing two values ​​(e.g., 0 and 1) of coresetPoolIndex in the ControlResourceSet, the first / second (uniform) TCI state activation command, as specified herein, may also incorporate / provide / indicate / include / contain the coresetPoolIndex value (e.g., 0 or 1). In this case, the TCI state / TCI code point activated by the first / second (uniform) TCI state activation command may be specific to the same coresetPoolIndex value (i.e., 0 or 1) provided / indicated therein.

[0148] In one example, when the UE is not provided / configured with two values ​​(e.g., 0 and 1) of PDCCH-Config and / or coresetPoolIndex in ControlResourceSet, and / or when the UE is not provided / configured with two values ​​(e.g., 0 and 1) of PDCCH-Config and / or coresetPoolIndex in ControlResourceSet, and / or when the UE is provided / configured by a higher-level parameter PDCCH-Config containing a single value (e.g., 0) of coresetPoolIndex in ControlResourceSet, the UE may or may not expect, or may or may not expect to receive a third (unified) TCI state activation MAC CE command, wherein the TCI code point activated by the third (unified) TCI state activation MAC CE command may include one of the following or map to one of the following or may correspond to one of the following:

[0149] - Case 19: A first TCI state for the DL channel / signal, and / or a first TCI state for the UL channel / signal, and / or a pair of TCI states, wherein each pair includes a first TCI state for the DL channel / signal and a first TCI state for the UL channel / signal.

[0150] - Case 20: A second TCI state for the DL channel / signal, and / or a second TCI state for the UL channel / signal, and / or a pair of TCI states, wherein each pair includes a second TCI state for the DL channel / signal and a second TCI state for the UL channel / signal.

[0151] -Case 21: First TCI state for both DL and UL channels / signals

[0152] -Case 22: Second TCI state for both DL and UL channels / signals

The RS index in the RS set of the second TCI state in a set of one or more (e.g., N=2) TCI states / TCI state pairs indicated in the CE has the same value. The second TCI state is used to receive / monitor PDCCH / PDCCH candidates configured / associated with a first indicator set to "10" or "11" as specified herein, wherein both the first and second TCI states are used for one or more CORESETs.

The first TCI state in one or more (e.g., N=2) TCI state / TCI state pairs indicated in the CE, and the second radio link quality of the second BFD RS set q0_1 can be evaluated according to the SSB or periodic CSI-RS resource configuration on the PCell or PSCell, the SSB or periodic CSI-RS resource configuration being in the second TCI state in one or more (e.g., N=2) TCI state / TCI state pairs indicated in the CE, for example by the TCI code point in the beam indication DCI or MAC as specified herein, wherein the first indicator configured for or associated with the PDCCH / PDCCH candidates (e.g., first and second PDCCH candidates) received in the CORESET as specified herein can be set to "10" or "11".

[0249] For any or every BFD RS set specified herein, if the higher layer receives radio link quality from the physical layer in the UE that is worse than the threshold Qout for the BFD RS set, the higher layer in the UE will increment the beam failure instance (BFI) count in the BFI counter (denoted as BFI_COUNTER) associated with / corresponding to the BFD RS set. If the BFI count in the BFI counter BFI_COUNTER for the BFD RS set reaches the maximum number of BFI counts (e.g., provided by the higher layer parameter maxBFIcount) before the BFD timer expires, then the UE will declare a beam failure for the BFD RS set. After the higher layer in the UE declares a beam failure for the BFD RS set, the higher layer in the UE will reset the BFI count in the corresponding / associated BFI counter BFI_COUNTER or the BFD timer to zero.

[0250] For any or every BFD RS set specified herein, the UE may, for example, configure a new beam identifier (NBI) RS set (corresponding to / associated with the BFD RS set) via the network, provided by the higher-layer parameter candidateBeamRSList, for radio link quality measurements. The NBI RS set (as discussed herein, corresponding to / associated with the BFD RS set) is used to identify new beams to recover failed beams / links (and therefore, corresponding channels / signals or TRPs) of the BFD RS set. The UE expects single-port or dual-port CSI-RS with a frequency density equal to 1 or 3 REs per resource block (RB). The UE can evaluate radio link quality against a threshold Qin based on the resource-configured NBI RS set. The UE applies the Qin threshold to L1-RSRP measurements obtained from SSBs in the NBI RS set and, after scaling the corresponding CSI-RS received power using a value provided by powerControlOffset, applies the Qin threshold to L1-RSRP measurements obtained from CSI-RS resources in the NBI RS set. Based on L1-RSRP measurements, the UE can identify the periodic CSI-RS resource configuration index or SSB index in the NBI RS set, represented by q_new, which corresponds to the maximum / highest measured L1-RSRP in the L1-RSRP that is greater than or equal to the Qin threshold.

[0251] Figure 10 An example procedure 1000 for beam reset / update is shown according to an embodiment of the present disclosure. For example, the procedure 1000 for beam reset / update can be provided by… Figure 1 This is performed by UE 116 and gNB 102 and / or network 130 in wireless network 100. This example is for illustration only, and other embodiments may be used without departing from the scope of this disclosure.

[0252] The procedure begins at 1010, where the UE sends a beam failure declaration for the BFDRS set associated with the first TCI state to gNB 102 and / or network 130, including BFRQ and BFR MAC CE. At 1020, gNB 102 and / or network 130 send a beam failure recovery response (BFRR) to UE 116. At 1030, UE 116 resets / updates the beams used for various channels and / or signals, for example, according to q_new.

[0253] The BFD RS set may be associated with / correspond to one or more TCI states, which are at least for UE-specific DL and / or UL channels / signals, in a set of one or more (e.g., N=2) TCI states / TCI state pairs indicated by TCI code points, as specified herein in the beam indication DCI or MAC CE. For example, a BFD RS set may include a periodic CSI-RS resource configuration index or an SSB index (also known as a BFD RS resource index) having the same value as the RS index in the RS set of a set of one or more (e.g., N=2) TCI states / TCI state pairs indicated by TCI code points in a beam indication DCI or MAC CE as specified herein; in this case, whether to use / apply the first TCI state and / or the second TCI state may be determined based on one or more of the following: (1) fixed in the system specification, (2) configured / provided / indicated by the network, for example, via higher-layer RRC signaling / parameters and / or MAC CE commands and / or L1 signaling based on dynamic DCI, and (3) dependent on the first, second, third and / or fourth indicators as specified herein and / or their association with the first, second, third and / or fourth indicators. For another example, the UE can evaluate the radio link quality of the BFD RS set indicated by the RRC configuration and / or MAC CE based on the RS index in the RS set in the first TCI state and / or the second TCI state (e.g., for N=2), the first TCI state and / or the second TCI state being one or more (e.g., N=2) TCI state / TCI state pairs in the beam indication DCI or MAC CE as specified herein; in this case, the use / application of the first TCI state and / or the second TCI state can be determined based on one or more of the following: (1) fixed in the system specification, (2) configured / provided / indicated by the network, e.g., via higher-layer RRC signaling / parameters and / or MAC CE commands and / or L1 signaling based on dynamic DCI, and (3) dependent on the first, second, third and / or fourth indicators as specified herein and / or their association with the first, second, third and / or fourth indicators.To configure / determine one or more BFD RSs in one or more BFD RS sets as specified herein, a first TCI state or a second TCI state as specified herein may correspond to a joint DL and UL TCI state provided by TCI-State / DLorJointTCI-State, a separate DL TCI state provided by TCI-State / DLorJointTCI-State, or a separate DL TCI state in a pair of DL and UL TCI states. Throughout this disclosure, if the radio link quality of one or more BFD RSs in one or more BFD RS sets (or equivalently, the radio link quality of one or more BFD RS sets) is higher than a threshold (e.g., Q). out, If the LR is poor, then the UE (higher layer) can declare beam failure of one or more BFD RSs in one or more BFD RS sets (or equivalently, one or more BFD RS sets).

[0254] In embodiments, the UE can monitor and declare beam failure of a single TRP in a (single DCI-based) multi-TRP (MTRP) system. As specified herein, the UE can evaluate the radio link quality of one or more BFD RSs in one or more BFD RS sets associated with a first TCI state or a second TCI state in a set of one or more (e.g., N=2) TCI state / TCI state pairs indicated by TCI code points in a beam indicative DCI or MAC CE as specified herein. In this case, the UE (and its higher layers) can declare radio link quality worse than Q. out,Beam failure of one or more BFD RS sets of LR (and therefore, the corresponding / associated first or second TCI state). As specified herein, one or more BFD RS sets corresponding to or associated with a first TCI state or a second TCI state (and therefore one or more BFD RS sets provided therein) may be associated with the first TCI state based on the value of a first indicator configured for CORESET / PDCCH reception (e.g., when the first indicator is set to "00" / if the first indicator is set to "00", the BFD RS set is associated with the second TCI state, and when the first indicator is set to "01" / if the first indicator is set to "01") and / or based on a second indicator indicating PDSCH reception (e.g., when the second indicator is set to "00" / if the second indicator is set to "00", the BFD RS set is associated with the first TCI state, and when the second indicator is set to "01" / if the second indicator is set to "01") and / or based on a third indicator configured for PUCCH transmission (e.g., when the third indicator is set to "00" / if the third indicator is set to "00", the BFD RS set is associated with the second TCI state). The RS set is associated with the first TCI state, while the BFD RS set is associated with the second TCI state when the third indicator is set to "01" / if the third indicator is set to "01" and / or can be associated with the second TCI state based on the fourth indicator indicated for PUSCH transmission (e.g., the BFD RS set is associated with the first TCI state when the fourth indicator is set to "00" / if the fourth indicator is set to "00", while the BFD RS set is associated with the second TCI state when the fourth indicator is set to "01" / if the fourth indicator is set to "01").

[0255] In one example, the UE can declare a beam failure associated with a set of BFD RS associated with a first TCI state in one or more (e.g., N=2) TCI state / TCI state pairs, indicated by the TCI code point in the beam indication DCI or MAC CE as specified herein. For this design example, after the UE has sent a beam failure recovery request (BFRQ) to the network and with a ratio Q... out， After obtaining the necessary information related to the BFD RS set with radio link quality of LR and other differences, the UE can expect to receive a beam failure recovery response (BFRR) from the network. Upon receiving the BFRR, the UE can reset / update the beams used to transmit or receive channels / signals associated with the BFD RS set (and therefore, the first TCI state) as newly identified beams.

For this example, the UE will not reset / update the beams for PDSCH and PUSCH according to index q_new because they are associated with / related to the first TCI state—e.g., the second and fourth indicators for PDSCH and PUSCH are set to "00".

[0313] In an embodiment, the UE can monitor and declare beam failures of one or more TRPs in an MTRP system (based on a single DCI). As specified herein, the UE can evaluate the radio link quality of one or more BFD RSs in a set of one or more (e.g., N=2) TCI state / TCI state pairs associated with a first TCI state and / or a second TCI state in a beam indication DCI or MAC CE as specified herein. In this case, the UE (at higher layers) can declare radio link quality worse than Q. out,Beam failure of one or more BFDRS sets of LR (and therefore, the corresponding / associated first and / or second TCI states). As specified herein, one or more BFD RS sets corresponding to / associated with the first TCI state and / or the second TCI state (and therefore one or more BFD RSs provided therein) can be associated with the first TCI state based on the value of a first indicator configured for CORESET / PDCCH reception (e.g., when the first indicator is set to "00" / if the first indicator is set to "00", the BFD RS set is associated with the first TCI state; when the first indicator is set to "01" / if the first indicator is set to "01", the BFD RS set is associated with the second TCI state; and when the first indicator is set to "10" or "11" / if the first indicator is set to "10" or "11", the BFD RS set is associated with both the first and second TCI states), and / or can be associated with a second indicator indicating PDSCH reception (e.g., when the second indicator is set to "00" / if the second indicator is set to "00", the BFD RS set is associated with the first TCI state; when the second indicator is set to "01" / if the second indicator is set to "01", the BFD RS set is associated with both the first and second TCI states). The RS set is associated with the second TCI state, and when the second indicator is set to "10" or "11" / if the second indicator is set to "10" or "11", the BFD RS set is associated with both the first and second TCI states, and / or can be associated with a third indicator configured for PUCCH transmission (e.g., when the third indicator is set to "00" / if the third indicator is set to "00", the BFD RS set is associated with the first TCI state; when the third indicator is set to "01" / if the third indicator is set to "01", the BFD RS set is associated with the second TCI state; and when the third indicator is set to "10" or "11" / if the third indicator is set to "10" or "11", the BFD RS set is associated with both the first and second TCI states), and / or can be associated with a fourth indicator indicating PUSCH transmission (e.g., when the fourth indicator is set to "00" / if the fourth indicator is set to "00", the BFD RS set is associated with the first TCI state; when the fourth indicator is set to "01" / if the fourth indicator is set to "01", the BFD RS set is associated with both the first and second TCI states, and / or can be associated with a fourth indicator indicating PUSCH transmission (e.g., when the fourth indicator is set to "00" / if the fourth indicator is set to "00", the BFD RS set is associated with the first TCI state; when the fourth indicator is set to "01", the BFD RS set is associated with the first TCI state, and / or can be associated with the second ... The RS set is associated with the second TCI state, while the BFDRS set is associated with both the first and second TCI states when the fourth indicator is set to "10" or "11" (if the fourth indicator is set to "10" or "11").

[0314] In one example, the UE can declare a beam failure associated with a set of BFD RS associated with both the first and second TCI states in one or more (e.g., N=2) TCI state / TCI state pairs, as indicated by the TCI code point in the beam indication DCI or MAC CE specified herein in this disclosure. For this design example, after the UE has sent a beam failure recovery request (BFRQ) to the network and with a ratio Q... out， After obtaining the necessary information related to the BFD RS set with radio link quality of LR and other differences, the UE can expect to receive a beam failure recovery response (BFRR) from the network. After receiving the beam failure recovery response, the UE can reset / update the beams used to transmit or receive channels / signals associated with the BFD RS set (and therefore the first TCI state and / or the second TCI state) as newly identified beams.

[0375] For example, the UE can use the same spatial domain filter as the spatial domain filter corresponding to q_new_0 to transmit (aperiodic) SRS associated with / corresponding to the first TCI state—for example, triggered by a DCI format / PDCCH received in a CORESET configured / associated with a first indicator set to “00”, as specified herein in this disclosure;

[0376] For another example, the UE may use the same spatial domain filter as the spatial domain filter corresponding to q_new_1 to transmit (aperiodic) SRS associated with / corresponding to the second TCI state—for example, triggered by a DCI format / PDCCH received in a CORESET configured / associated with a first indicator set to “01” as specified herein.

[0377] For example, the UE can use the same spatial domain filter as the spatial domain filter corresponding to q_new_0 and / or q_new_1 to transmit (aperiodic) SRS associated with / corresponding to the first TCI state and / or the second TCI state—for example, triggered by a DCI format / PDCCH received in a CORESET configured / associated with a first indicator set to “10” or “11” as specified herein in this disclosure;

[0389] Figure 13 An example procedure 1300 for beam reset / update according to an embodiment of the present disclosure is shown. For example, procedure 1300 for beam reset / update can be provided by… Figure 1 This is performed by UE 116 and gNB 102 and / or network 130 in wireless network 100. This example is for illustration only, and other embodiments may be used without departing from the scope of this disclosure.

[0390] The procedure begins at 1310, where the UE sends a beam failure declaration for the BFDRS set associated with the first TCI state to gNB 102 and / or network 130, including BFRQ and BFR MAC CE. At 1320, gNB 102 and / or network 130 send a beam failure recovery response (BFRR) to UE 116. At 1330, UE 116 resets / updates the beams for various channels and / or signals, for example, according to q_new_0. At 1340, UE 116 resets / updates the beams for various channels and / or signals, for example, according to q_new_1.

[0391] refer to Figure 13 The UE declares a beam failure in the BFD RS set associated with the first and second TCI states. 28 symbols after receiving the BFRR, the UE resets / updates the TCI states / beams used for receiving PDCCH-1 and PDSCH, and for transmitting PUCCH-1 and PUSCH, according to index q_new_0; simultaneously, the UE resets / updates the TCI states / beams used for receiving PDCCH-2 and for transmitting PUCCH-2, according to index q_new_1. (The text abruptly ends here.) Figure 13 As shown, PDCCH-1 is associated with the first TCI state because the corresponding first indicator is set to "00", and PDCCH-2 is associated with the second TCI state because the corresponding first indicator is set to "01". For PDSCH, it is associated with the first TCI state because the corresponding second indicator is set to "00". Furthermore, PUCCH-1 and PUCCH-2 are associated with the first and second TCI states, respectively, because their corresponding third indicators are set to "00" and "01", respectively. For PUSCH, it is associated with the second TCI state because the corresponding fourth indicator is set to "01".

[0392] In one example, the presence or absence of a first indicator for PDCCH reception can be configured by the network, for example, via higher-layer RRC signaling / parameters and / or MAC CE commands and / or L1 signaling based on dynamic DCI. When the first indicator is absent or not configured, the UE can use / apply a backoff or default TCI state / beam to receive / monitor the corresponding PDCCH. In this case, when the backoff or default TCI state corresponds to the first TCI state and / or the second TCI state, the UE can reset / update the TCI state / beam used for receiving / monitoring the PDCCH according to those specified herein for the corresponding first TCI state and / or second TCI state 28 symbols after receiving BFRR.

[0393] In one example, the presence or absence of a second indicator for PDSCH reception can be configured by the network, for example, via higher-layer RRC signaling / parameters and / or MAC CE commands and / or L1 signaling based on dynamic DCI. When the second indicator is absent or not configured, the UE can use / apply a backoff or default TCI state / beam to receive the corresponding PDSCH. In this case, when the backoff or default TCI state corresponds to the first TCI state and / or the second TCI state, the UE can reset / update the TCI state / beam for receiving PDSCH according to those specified herein for the corresponding first TCI state and / or second TCI state 28 symbols after receiving BFRR.

[0394] In one example, the presence or absence of a third indicator for PUCCH transmission can be configured by the network, for example, via higher-layer RRC signaling / parameters and / or MAC CE commands and / or L1 signaling based on dynamic DCI. When the third indicator is absent or not configured, the UE can use / apply a backoff or default TCI state / beam to transmit the corresponding PUCCH. In this case, when the backoff or default TCI state corresponds to the first TCI state and / or the second TCI state, the UE can reset / update the TCI state / beam used for transmitting the PUCCH according to those specified herein for the corresponding first TCI state and / or second TCI state 28 symbols after receiving BFRR.

[0395] In one example, the presence or absence of a fourth indicator for PUSCH transmission can be configured by the network, for example, via higher-layer RRC signaling / parameters and / or MAC CE commands and / or L1 signaling based on dynamic DCI. When the fourth indicator is absent or not configured, the UE can use / apply a backoff or default TCI state / beam to transmit the corresponding PUSCH. In this case, when the backoff or default TCI state corresponds to the first TCI state and / or the second TCI state, the UE can reset / update the TCI state / beam used for transmitting the PUSCH according to those specified herein for the corresponding first TCI state and / or second TCI state 28 symbols after receiving BFRR.

[0396] For MDCI-based MTRP operations (e.g., if the UE is provided with two coresetPoolIndex values ​​of 0 and 1 for the first and second CORESETs respectively, or is provided with a coresetPoolIndex value of 1 for the second CORESET but not for the first CORESET), the UE can receive from the network a (enhanced) unified TCI state activation / deactivation MAC CE command, which maps up to Ntci (e.g., Ntci=8) TCI states and / or TCI state pairs to TCI code points in the DCI field "Transmission Configuration Indication", where one TCI state is used for the DL channel / signal and / or one TCI state is used for the UL channel / signal, the DCI field "Transmission Configuration Indication" is used for one or a group of CC / DLBWPs, and, if applicable, for one or a group of CC / UL BWPs. If the (Enhanced) Unified TCI State Activation / Deactivation MAC CE command maps the TCI state and / or UL-TCI state to only one TCI code point, then once the indicated mapping for a single TCI code point is applied, the UE will apply the indicated TCI state and / or UL-TCI state to one or a set of CC / DL BWPs, and, if applicable, to one or a set of CC / UL BWPs. Furthermore, the (Enhanced) Unified TCI State Activation / Deactivation MAC CE command may also provide / indicate / configure / include / contain / include a coresetPoolIndex value field. When the coresetPoolIndex value field in the (Enhanced) Unified TCI State Activation / Deactivation MAC CE is set to "0" (or "1") / if the coresetPoolIndex value field in the (Enhanced) Unified TCI State Activation / Deactivation MAC CE is set to "0" (or "1"), the unified / DL / UL TCI state activated in the (Enhanced) Unified TCI State Activation / Deactivation MAC CE can be specific to coresetPoolIndex value 0 (or 1) / associated with coresetPoolIndex value 0 (or 1) / associated with coresetPoolIndex value 0 (or 1).

[0397] In one example, the UE may be instructed by the network, for one or more CC / DL BWPs, via one or more TCI code points in one or more DCIs (e.g., DCI formats 1_1 / 1_2 with or without DL assignment) received in one or more CORESETs associated with / configured with a coresetPoolIndex value of 0, and, if applicable, for one or more CC / UL BWPs, to indicate at least one TCI state for the DL channel / signal and / or one TCI state for the UL channel / signal; in this case, one TCI state for the DL channel / signal and / or one TCI state for the UL channel / signal may be specific to / associated with / related to the coresetPoolIndex value of 0. Furthermore, a TCI state for the DL channel / signal (and / or a TCI state for the UL channel / signal) may correspond to or replace the first TCI state used throughout this disclosure to specify beam reset behavior / operation in a multi-TRP system based on a single DCI, to specify beam reset behavior / operation in a multi-DCI-based multi-TRP system (e.g., if the UE is provided with two coresetPoolIndex values ​​of 0 and 1 for the first and second CORESETs respectively, or is not provided with a coresetPoolIndex value for the first CORESET and is provided with a coresetPoolIndex value of 1 for the second CORESET). Furthermore, in this case, any channel, signal, information, parameter, configuration, indication, setting, etc., that is associated with / specific to the first TCI state as specified throughout this disclosure may also be (referred to as) associated with / specific to the coresetPoolIndex value 0 in a multi-DCI-based multi-TRP system (e.g., if the UE is provided with two coresetPoolIndex values ​​0 and 1 for the first CORESET and the second CORESET respectively, or is not provided with a coresetPoolIndex value for the first CORESET and is provided with a coresetPoolIndex value 1 for the second CORESET).

[0398] In one example, a UE (e.g., UE 116) may be instructed by a network (e.g., network 130) for one or more CC / DL BWPs, for one or more DCIs (e.g., DCI formats 1_1 / 1_2 with or without DL assignment) received in one or more CORESETs associated with / configured with coresetPoolIndex value 1, via one or more TCI code points in one or more TCI fields of one or more CC / UL BWPs, and if applicable, for one or more CC / UL BWPs, indicating at least one TCI state for the DL channel / signal and / or one TCI state for the UL channel / signal; in this case, one TCI state for the DL channel / signal and / or one TCI state for the UL channel / signal may be specific to coresetPoolIndex value 1 / associated with coresetPoolIndex value 1 / associated with coresetPoolIndex value 1. Furthermore, a TCI state for the DL channel / signal (and / or a TCI state for the UL channel / signal) may correspond to or replace the second TCI state used throughout this disclosure to specify beam reset behavior / operation in a multi-TRP system based on a single DCI, to specify beam reset behavior / operation in a multi-DCI-based multi-TRP system (e.g., if the UE is provided with two coresetPoolIndex values ​​of 0 and 1 for the first and second CORESETs respectively, or is not provided with a coresetPoolIndex value for the first CORESET and is provided with a coresetPoolIndex value of 1 for the second CORESET). Furthermore, in this case, any channel, signal, information, parameter, configuration, indication, setting, etc. that are associated with / specific to the second TCI state as specified throughout this disclosure may also be (referred to as) associated with / specific to the coresetPoolIndex value 1 in a multi-DCI-based multi-TRP system (e.g., if the UE is provided with two coresetPoolIndex values ​​0 and 1 for the first CORESET and the second CORESET respectively, or is not provided with a coresetPoolIndex value for the first CORESET but is provided with a coresetPoolIndex value 1 for the second CORESET).

The TCI code point of the CE command is applied to the TCI field of DCI format 1_1 / 1_2 with the same value 0 of coresetPoolIndex, and activates / deactivates the second (uniform) TCI state from the value 1 of coresetPoolIndex. Alternatively, the UE may not expect to receive (uniform) TCI state activation / deactivation MAC CE commands that are not specific to any coresetPoolIndex value (e.g., the first (uniform) TCI state activation / deactivation MAC CE command as specified herein), and / or the UE may not expect to apply TCI code points (when they become applicable), TCI code points activated / in which are activated by (uniform) TCI state activation / deactivation MAC CE commands that are not specific to any coresetPoolIndex value, and / or the UE may not expect to apply TCI code points from (uniform) TCI state activation / deactivation MAC CE commands that are not specific to any coresetPoolIndex value to the TCI fields of DCI format 1_1 / 1_2.In this scenario / design example, when the first joint / DL / UL TCI state indicated by the TCI code point (activated / deactivated by the MAC CE command from the first (unified) TCI state specific to coresetPoolIndex value 0) and the second joint / DL / UL TCI state indicated by the TCI code point (activated / deactivated by the MAC CE command from the second (unified) TCI state specific to coresetPoolIndex value 1) have become applicable (e.g., after the corresponding beam application time) / if the first joint / DL / UL TCI state indicated by the TCI code point (activated / deactivated by the MAC CE command from the first (unified) TCI state specific to coresetPoolIndex value 0) and the second joint / DL / UL TCI state indicated by the TCI code point (activated / deactivated by the MAC CE command from the second (unified) TCI state specific to coresetPoolIndex value 1) have become applicable (e.g., after the corresponding beam application time),

Alternatively, the UE may not expect to receive (uniform) TCI state activation / deactivation MAC CE commands that are not specific to any coresetPoolIndex value (e.g., the first (uniform) TCI state activation / deactivation MAC CE command as specified herein), and / or the UE may not expect to apply TCI code points (when they become applicable), TCI code points activated / in which are activated by (uniform) TCI state activation / deactivation MAC CE commands that are not specific to any coresetPoolIndex value, and / or the UE may not expect to apply TCI code points from (uniform) TCI state activation / deactivation MAC CE commands that are not specific to any coresetPoolIndex value to the TCI fields of DCI format 1_1 / 1_2.In this scenario / design example, when the first joint / DL / UL TCI state indicated by the TCI code point (activated / deactivated by the MAC CE command from the first (unified) TCI state specific to coresetPoolIndex value 0) and the second joint / DL / UL TCI state indicated by the TCI code point (activated / deactivated by the MAC CE command from the second (unified) TCI state specific to coresetPoolIndex value 1) have become applicable (e.g., after the corresponding beam application time) / if the first joint / DL / UL TCI state indicated by the TCI code point (activated / deactivated by the MAC CE command from the first (unified) TCI state specific to coresetPoolIndex value 0) and the second joint / DL / UL TCI state indicated by the TCI code point (activated / deactivated by the MAC CE command from the second (unified) TCI state specific to coresetPoolIndex value 1) have become applicable (e.g., after the corresponding beam application time),

[0550] The UE may apply a first joint / DL / UL TCI state, indicated by a coresetPoolIndex value of 0, to monitor the PDCCH in the first CORESET, and receive PDSCHs scheduled / activated by the PDCCHs in the first CORESET, as well as aperiodic CSI-RS resources applying a TCI-State specific to the first CORESET, and / or transmit PUSCH, PUCCH, and SRS applying a TCI-State or TCI-UL-State specific to the first CORESET, and / or apply a second joint / DL / UL TCI state, indicated by a coresetPoolIndex value of 1, to monitor the PDCCH in the second CORESET, and receive PDSCHs scheduled / activated by the PDCCHs in the second CORESET, as well as aperiodic CSI-RS resources applying a TCI-State specific to the second CORESET, and / or transmit PUSCH, PUCCH, and SRS applying a TCI-State or TCI-UL-State specific to the second CORESET.

[0551] Furthermore, in wireless communication systems, a radio link failure (RLF) may occur if a significant / sudden degradation of link quality is observed at the UE side. Therefore, a fast RLF recovery mechanism becomes essential for rapidly rebuilding the communication link and avoiding severe service interruptions in the event of an RLF. At higher frequencies, such as millimeter wave (mmWave) frequencies or FR2 in 3GPP NR, both transmitters and receivers can use directional (analog) beams to transmit and receive various RS / channels, such as SSB, CSI-RS, PDCCH, or PDSCH. Therefore, before declaring a full RLF, if the signal quality / strength of certain beamp-to-link (BPL) links falls below a certain threshold for a certain period, the UE can first detect and recover from the beam failure.

[0552] The 3GPP Rel.15 Beam Failure Recovery (BFR) procedure is primarily for primary cells (PCell or PSCell) under the Carrier Aggregation (CA) framework. Figure 8 The BFR specification in 3GPP Rel.15 includes the following key components:

[0553] - Beam Failure Detection (BFD)

[0554] - New Beam Identification (NBI)

[0555] -BFR Request (BFRQ)

[0556] -BFRQ response (BFRR)

[0557] The UE is first configured by the gNB (e.g., gNB 102) with a set of BFD RS resources to monitor the link quality between the gNB and the UE. One BFD RS resource may correspond to one (periodic) CSI-RS / SSB RS resource, which can be a Type D quasi-co-located (QCL) source RS in the TCI state of CORESET. If the received signal quality of the BFD RS resource is below a given threshold (meaning the assumed BLER of the corresponding CORESET / PDCCH is above the given threshold), the UE can declare a beam failure instance (BFI). Furthermore, if the UE has declared N_BFI consecutive BFIs within a given time period, the UE will declare a beam failure.

[0558] Upon claiming / detecting a beam failure, the UE will send a BFRQ to the gNB via a contention-free (CF) PRACH (CF BFR-PRACH) resource, the index of which is associated with a new beam identified by the UE. Specifically, to determine the new beam, the UE can first have a set of SSB and / or CSI-RS resources (NBI RS resources) configured by the network via the higher-layer parameter candidateBeamRSList. The UE will then measure the NBI RSs and calculate their L1-RSRPs. If at least one of the measured L1-RSRPs of an NBI RS exceeds a given threshold, the UE will select the beam corresponding to the NBI RS with the highest L1-RSRP as the new beam q_new. To determine the CF BFR-PRACH resource for conveying the BFRQ, the UE can first have a set of PRACH resources configured by the network, each PRACH resource associated with an NBI RS resource. The UE can then select the PRACH resource with a one-to-one correspondence with the selected NBI RS resource (and therefore, the new beam index q_new) to send the BFRQ to the gNB. Based on the index of the selected CFPRACH resource, the gNB can also know which beam the UE chooses as the new beam.

[0559] Four time slots after the UE has sent the BFRQ, the UE can begin monitoring a dedicated CORESET / search space for BFRQ responses. The dedicated CORESET is addressed to the UE-specific C-RNTI and will be transmitted by the gNB using a newly identified beam. If the UE detects a valid UE-specific DCI in the dedicated CORESET used for BFRR, the UE anticipates that the beam failure recovery request has been successfully received by the network, and the UE will complete the BFR procedure. Otherwise, if the UE does not receive the BFRR within the configured time window, the UE will initiate a contention-based (CB) random access (RA) procedure to reconnect to the network.

[0560] In 3GPP Rel. 16, BFR procedures are customized for secondary cells (SCells) under the CA framework, where it is expected that BPL between the PCell and the UE is already in operation. (Reference) Figure 9 An illustrative example of SCell beam failure is given.

[0561] After declaring / detecting a beam failure in an SCell, the UE will send a BFRQ in the form of a Scheduling Request (SR) on the PUCCH of the working PCell. Furthermore, the UE can send the BFRQ only at this stage without indicating any new beam index, failed SCell index, or other information to the network. This differs from the Rel. 15 PCell / PSCell protocol, where the UE indicates both the BFRQ and the identified new beam index to the network simultaneously. Allowing the gNB to quickly know the beam failure status of an SCell without waiting for the UE to identify a new beam can be beneficial. For example, the gNB can deactivate the failed SCell and allocate resources to other working SCells.

[0562] The network can respond to the BFRQ SR by indicating uplink grant to the UE, which will allocate the necessary resources for the MAC CE to carry the new beam index q_new (if identified), failed SCell index, etc., on the PUSCH of the working PCell. After sending the MAC CE for BFR to the working PCell, the UE will begin monitoring the BFRR. The BFRR can be the TCI status indication of the corresponding SCell's CORESET. The BFRR to the MAC CE for BFR can also be a normal uplink grant for scheduling a new transmission using the same HARQ procedure as the PUSCH carrying the MAC CE for BFR. If the UE cannot receive the BFRR within the configured time window, the UE can resend the BFR-PUCCH or fall back to the contention-based random access (CBRA) procedure.

[0563] This disclosure provides various design aspects relating to the transmission of beam failure recovery requests (BFRQs) and information related to beams with radio link quality below a threshold in a multi-TRP system, wherein beam / TRP selection is performed within a unified TCI framework.

[0564] As specified in Rel-17, the unified TCI framework may indicate / include N ≥ 1 DL TCI states and / or M ≥ 1 ULTCI states, wherein the indicated TCI state may be at least one of the following:

[0565] -DL TCI status and / or its corresponding / associated TCI status ID

[0566] -UL TCI status and / or its corresponding / associated TCI status ID

[0567] - Combine DL and UL TCI status and / or its corresponding / associated TCI status ID

[0568] - Individual DL TCI status and UL TCI status and / or their corresponding / associated TCI status ID

[0569] Various design options / channels can exist to indicate to the UE the beams (i.e., TCI states) used for PDCCH or PDSCH transmission / reception. As described in 3GPP Rel-17,

[0570] - In one example, the MAC CE can be used to indicate to the UE the beam used for transmitting / receiving PDCCH or PDSCH (i.e., TCI status and / or TCI status ID).

[0571] - In another example, DCI can be used to indicate to the UE the beam used for transmitting / receiving PDCCH or PDSCH (i.e., TCI status and / or TCI status ID).

[0572] For example, DL-related DCI (e.g., DCI format 1_0, DCI format 1_1, or DCI format 1_2) can be used to indicate to the UE the beam for transmission / reception of PDCCH or PDSCH (i.e., TCI status and / or TCI status ID), wherein DL-related DCI may or may not include DL assignment.

[0573] For another example, UL-related DCIs (e.g., DCI format 0_0, DCI format 0_1, DCI format 0_2) can be used to indicate to the UE the beams for transmitting / receiving PDCCH or PDSCH (i.e., TCI status and / or TCI status ID), where the UL-related DCIs may or may not include UL scheduling authorization.

[0574] For example, a custom / purpose-designed DCI format can be used to indicate to the UE the beams for transmitting / receiving PDCCH or PDSCH (i.e., TCI status and / or TCI status ID).

[0575] Rel-17 introduced a unified TCI framework, in which the unified, primary, or major TCI status is signaled to the UE. The unified, primary, or major TCI status can be one of the following:

[0576] - In the case of a joint TCI status indication, where the same beam is used for the DL and UL channels, the joint TCI status can be used for at least the UE-dedicated DL channel and the UE-dedicated UL channel.

[0577] - In the case of separate TCI status indication, where different beams are used for DL ​​and UL channels, the DL TCI status can be used at least for the UE-dedicated DL channel.

[0578] - In the case of separate TCI status indication, where different beams are used for DL ​​and UL channels, the UL TCI status can be used at least for the UE-dedicated UL channel.

[0579] The unified (primary or main) TCI status is the TCI status of UE-dedicated reception on PDSCH / PDCCH or PUSCH and dedicated PUCCH resources based on dynamic authorization / configuration authorization.

[0580] The UE (e.g., UE 116) can receive a first (uniform) TCI state activation MACCE command and / or a second (uniform) TCI state activation MACCE command from the network (e.g., network 130). The first (uniform) TCI state activation MACCE command is used to map up to 8 TCI states and / or TCI state pairs to code points in the DCI field "Transmission Configuration Indication" of one or a set of CC / DL BWPs, where each pair includes one TCI state for the DL channel / signal and / or one TCI state for the UL channel / signal. The second (uniform) TCI state activation MACCE command is used to map up to 8 sets of TCI states to one or a set of CC / DL BWPs and, if applicable, one or a set of CC / UL BWPs. The DCI field "Transmission Configuration Indication" code points of the BWP can include up to two (e.g., none, one, or two) TCI states for DL ​​and UL signals / channels, and / or up to two (e.g., none, one, or two) TCI states for DL ​​channels / signals and / or up to two (e.g., none, one, or two) TCI states for UL channels / signals. When a set of TCI state IDs is activated for a set of CC / DL BWPs and, if applicable, for a set of CC / UL BWPs, the applicable list of CCs is determined by the CCs indicated in the activation command, and the same set of TCI state IDs is applied to the DL and / or UL BWPs in the indicated CCs. If the first / second MAC CE activation command maps TCI-State and / or TCI-UL-State to only one TCI code point, once the indicated mapping for a single TCI code point is applied, the UE should apply the indicated TCI-State and / or TCI-UL-State to one or a set of component carrier CC / DL BWPs and, if applicable, one or a set of CC / UL BWPs. In other words, for example, when the UE is provided / configured with dl-OrJointTCI-StateList and / or ul-TCI-StateList and / or has one or two indicated TCI states and / or has a first and / or a second indicated TCI state, the activated TCI code point in the second MAC CE activation command can consist of / include one of the following:

[0581] Case 1: First TCI state for DL ​​channel / signal

[0582] - Case 2: First TCI state for DL ​​channel / signal and second TCI state for DL ​​channel / signal

[0583] -Scenario 3: First TCI state for DL ​​channel / signal and second TCI state for UL channel / signal

[0584] Case 4: A first TCI state for the DL channel / signal and a pair of second TCI states for the DL channel / signal and a second TCI state for the UL channel / signal.

[0585] - Case 5: First TCI state for UL channel / signal

[0586] - Case 6: First TCI state for UL channel / signal and second TCI state for DL ​​channel / signal

[0587] - Case 7: First TCI state for UL channel / signal and second TCI state for UL channel / signal

[0588] Case 8: A first TCI state for the UL channel / signal and a pair of second TCI states for the DL channel / signal and a second TCI state for the UL channel / signal.

[0589] Case 9: A pair of first TCI states for DL ​​channel / signal and first TCI states for UL channel / signal

[0590] - Case 10: A pair of first TCI states for DL ​​channel / signal and first TCI states for UL channel / signal, and a second TCI state for DL ​​channel / signal.

[0591] Case 11: A pair of first TCI states for DL ​​channel / signal and first TCI states for UL channel / signal, and a second TCI state for UL channel / signal.

[0592] Case 12: A pair of first TCI states for DL ​​channel / signal and a pair of second TCI states for UL channel / signal, and a pair of second TCI states for DL ​​channel / signal and a pair of second TCI states for UL channel / signal.

[0593] -Case 13: Second TCI state for DL ​​channel / signal

[0594] -Case 14: Second TCI State for UL Channel / Signal

[0595] -Case 15: A pair of second TCI states for DL ​​channel / signal and a pair of second TCI states for UL channel / signal

[0596] -Case 16: First TCI state for DL ​​channel / signal and UL channel / signal

[0597] - Case 17: Second TCI state for DL ​​channel / signal and UL channel / signal

[0598] -Case 18: A pair of first TCI states for DL ​​channel / signal and UL channel / signal and a second TCI state for DL ​​channel / signal and UL channel / signal.

[0599] Furthermore, when the UE is configured by a higher-level parameter PDCCH-Config containing two values ​​(e.g., 0 and 1) of coresetPoolIndex in the ControlResourceSet, the first / second (uniform) TCI state activation command, as specified herein, may also incorporate / provide / indicate / include / contain the coresetPoolIndex value (e.g., 0 or 1). In this case, the TCI state / TCI code point activated by the first / second (uniform) TCI state activation command may be specific to the same coresetPoolIndex value (i.e., 0 or 1) provided / indicated therein.

[0600] In one example, when the UE is not provided / configured with two values ​​(e.g., 0 and 1) of PDCCH-Config and / or coresetPoolIndex in ControlResourceSet, and / or when the UE is not provided / configured with two values ​​(e.g., 0 and 1) of PDCCH-Config and / or coresetPoolIndex in ControlResourceSet, and / or when the UE is provided / configured by a higher-level parameter PDCCH-Config containing a single value (e.g., 0) of coresetPoolIndex in ControlResourceSet, the UE may or may not expect, or may or may not expect to receive a third (unified) TCI state activation MAC CE command, wherein the TCI code point activated by the third (unified) TCI state activation MAC CE command may include one of the following or map to one of the following or may correspond to one of the following:

[0603] -Case 21: First TCI state for both DL and UL channels / signals

[0604] -Case 22: Second TCI state for both DL and UL channels / signals

[0605] In other words, the TCI code point activated by the third (unified) TCI state activation command / activated in the third (unified) TCI state activation command can include or be mapped to the first union / DL / UL TCI state / first DL and UL TCI state pair or the second union / DL / UL TCI state / second DL and UL TCI state pair.
