[0040] For example, in a network supporting NR 5G, the UE can transmit CSI reports to the network (e.g., base stations associated with the network). For example, the CSI report may include CSI feedback describing various CSIs. In some implementations, the CSI feedback may include one or more forms based on CSI format, frequency-domain CSI reporting granularity (e.g., wideband, subband, etc.), and / or time-domain behavior (e.g., periodicity of CSI feedback in the time domain (e.g., periodic CSI feedback, aperiodic CSI feedback, semi-persistent CSI feedback, etc.)). For example, channel characteristic changes due to high UE speed or irregular interference bursts may result in unequal coherence periods. Periodic CSI reporting may be inefficient due to unequal intervals between consecutive reporting moments. Aperiodic CSI reporting triggered by network-based events (e.g., negative acknowledgments (NACK) indicating decoding failure) causes delays. It should be noted that the UE can also provide rapid updates on the CSI status due to sudden channel changes or burst interference.

[0041] This disclosure relates to event-triggered CSI reporting based on UE-assisted signaling. For example, an enhanced beam management (BM) framework is described that supports a multi-stage approach for event-triggered BM, including a beam acquisition phase (e.g., where the UE participates in the beam acquisition process), a UE-assisted beam monitoring phase (e.g., where the UE monitors beam characteristics, such as beam CSI), and a beam switching phase (e.g., where the UE acquires a new beam for wireless communication). Furthermore, a set of beam switching conditions corresponding to a UE-triggered beam switching event is described, wherein the UE can transmit an uplink (UL) signal when a subset of the set of beam switching conditions is met. Additionally, a beam switching framework triggered by the UL signal is described, which, for example, enables rapid beam updates based on pre-configured CSI report settings.

[0042] By utilizing the described technology, more efficient and accurate beam CSI reporting can be achieved, which can be used as part of wireless communication to reduce network overhead and improve signal quality.

[0043] This disclosure is described in the context of wireless communication systems.

[0044] Figure 1 This describes an example of a wireless communication system 100 according to aspects of this disclosure. The wireless communication system 100 may include one or more NEs 102, one or more UEs 104, and a core network (CN) 106. The wireless communication system 100 may support various radio access technologies. In some embodiments, the wireless communication system 100 may be a 4G network, such as an LTE network or an advanced LTE (LTE-A) network. In some other embodiments, the wireless communication system 100 may be an NR network, such as a 5G network, an advanced 5G (5G-A) network, or a 5G ultra-wideband (5G-UWB) network. In other embodiments, the wireless communication system 100 may be a combination of 4G and 5G networks, or other suitable radio access technologies, including IEEE 802.11 (Wi-Fi), IEEE 802.16 (WiMAX), and IEEE 802.20. The wireless communication system 100 may support radio access technologies beyond 5G, such as 6G. In addition, the wireless communication system 100 can support technologies such as Time Division Multiple Access (TDMA), Frequency Division Multiple Access (FDMA), or Code Division Multiple Access (CDMA).

[0045] One or more NEs 102 may be distributed throughout a geographic area to form a wireless communication system 100. One or more of the NEs 102 described herein may be, include, or be referred to as a network node, base station, network element, network function, network entity, radio access network (RAN), NodeB, eNodeB (eNB), next-generation NodeB (gNB), or other suitable terms. NEs 102 and UEs 104 may communicate via a communication link, which may be a wireless or wired connection. For example, NEs 102 and UEs 104 may perform wireless communication (e.g., receive signaling, transmit signaling) via a Uu interface.

[0046] NE 102 can provide a geographic coverage area, for which NE 102 can support services of one or more UE 104s within the geographic coverage area. For example, NE 102 and UE 104 can support wireless communication of signals related to services (e.g., voice, video, packet data, messaging, broadcasting, etc.) according to one or more radio access technologies. In some embodiments, NE 102 can be mobile, for example, a satellite associated with a non-terrestrial network (NTN). In some embodiments, different geographic coverage areas associated with the same or different radio access technologies may overlap, but different geographic coverage areas may be associated with different NE 102s.

[0047] One or more UEs 104 may be distributed throughout the geographic area of ​​the wireless communication system 100. UE 104 may include or be referred to as a remote unit, mobile device, wireless device, remote device, subscriber device, transmitter device, receiver device, or some other suitable term. In some embodiments, UE 104 may be referred to as a unit, station, terminal, or client, and other instances. Alternatively or additionally, UE 104 may be referred to as an Internet of Things (IoT) device, an Internet of Everything (IoE) device, or a Machine-Type Communication (MTC) device, and other instances.

[0048] UE 104 may be able to support direct wireless communication with other UE 104 via a communication link. For example, UE 104 may support direct wireless communication with another UE 104 via a device-to-device (D2D) communication link. In some implementations (e.g., vehicle-to-vehicle (V2V) deployment, vehicle-to-everything (V2X) deployment, or cellular V2X deployment), the communication link may be referred to as a sidelink. For example, UE 104 may support direct wireless communication with another UE 104 via a PC5 interface.

[0049] NE 102 may support communication with CN 106 or another NE 102, or both. For example, NE 102 may interface with other NE 102 or CN 106 via one or more backhaul links (e.g., S1, N2, N6, or other network interfaces). In some embodiments, NE 102 may communicate directly with each other. In some other embodiments, NE 102 may communicate indirectly with each other (e.g., via CN 106). In some embodiments, one or more NE 102 may include sub-components, such as access network entities, which may be instances of access node controllers (ANCs). The ANC may communicate with one or more UEs 104 via one or more other access network transport entities, which may be referred to as wireless heads, smart wireless heads, or transmit-receive points (TRPs).

[0050] CN 106 can support user authentication, access authorization, tracking, connectivity, and other access, routing, or mobility functions. CN 106 can be an evolved packet core (EPC) or a 5G core (5GC), which may include control plane entities that manage access and mobility (e.g., a mobility management entity (MME), access and mobility management functions (AMF)) and user plane entities that route packets to or interconnect to external networks (e.g., a serving gateway (S-GW), a packet data network (PDN) gateway (P-GW), or a user plane function (UPF)). In some implementations, the control plane entities may manage non-access stratum (NAS) functions of one or more UEs 104 served by one or more NEs 102 associated with CN 106, such as mobility, authentication, and bearer management (e.g., data bearers, signaling bearers, etc.).

[0051] CN 106 can communicate with the packet data network via one or more backhaul links (e.g., via S1, N2, N6, or other network interfaces). The packet data network may contain an application server. In some implementations, one or more UEs 104 can communicate with the application server. UE 104 can establish a session (e.g., a Protocol Data Unit (PDU) session or the like) with CN 106 via NE 102. CN 106 can use the established session (e.g., an established PDU session) to route services (e.g., control information, data, and the like) between UE 104 and the application server. A PDU session can be an instance of a logical connection between UE 104 and CN 106 (e.g., one or more network functions of CN 106).

[0052] In the wireless communication system 100, NE 102 and UE 104 can use the resources of the wireless communication system 100 (e.g., time resources (e.g., symbols, time slots, subframes, frames, or the like) or frequency resources (e.g., subcarriers, carriers)) to perform various operations (e.g., wireless communication). In some embodiments, NE 102 and UE 104 may support different resource structures. For example, NE 102 and UE 104 may support different frame structures. In some embodiments, such as in 4G, NE 102 and UE 104 may support a single frame structure. In some other embodiments, such as in 5G and other suitable radio access technologies, NE 102 and UE 104 may support various frame structures (e.g., multiple frame structures). NE 102 and UE 104 may support various frame structures based on one or more parameter sets.

[0053] The wireless communication system 100 may support one or more parameter sets, and the parameter sets may include subcarrier spacing and cyclic prefixes. A first parameter set (e.g., μ=0) may be associated with a first subcarrier spacing (e.g., 15 kHz) and a regular cyclic prefix. In some embodiments, the first parameter set (e.g., μ=0) associated with the first subcarrier spacing (e.g., 15 kHz) may utilize one time slot per subframe. A second parameter set (e.g., μ=1) may be associated with a second subcarrier spacing (e.g., 30 kHz) and a regular cyclic prefix. A third parameter set (e.g., μ=2) may be associated with a third subcarrier spacing (e.g., 60 kHz) and a regular cyclic prefix or an extended cyclic prefix. A fourth parameter set (e.g., μ=3) may be associated with a fourth subcarrier spacing (e.g., 120 kHz) and a regular cyclic prefix. A fifth parameter set (e.g., μ=4) may be associated with a fifth subcarrier spacing (e.g., 240 kHz) and a regular cyclic prefix.

[0054] Time intervals for resources (e.g., communication resources) can be organized according to frames (also known as radio frames). Each frame may have a certain duration, for example, 10 milliseconds (ms). In some embodiments, each frame may contain multiple subframes. For example, each frame may contain 10 subframes, and each subframe may have a certain duration, for example, 1 ms. In some embodiments, each frame may have the same duration. In some embodiments, each subframe of a frame may have the same duration.

[0055] Alternatively, the time intervals of resources (e.g., communication resources) can be organized according to time slots. For example, a subframe may contain a certain number (e.g., quantity) of time slots. The number of time slots in each subframe may also depend on one or more parameter sets supported in the wireless communication system 100. For example, the first, second, third, fourth, and fifth parameter sets (e.g., μ=0, μ=1, μ=2, μ=3, μ=4) associated with corresponding subcarrier intervals of 15 kHz, 30 kHz, 60 kHz, 120 kHz, and 240 kHz may utilize one time slot per subframe, two time slots per subframe, four time slots per subframe, eight time slots per subframe, and 16 time slots per subframe, respectively. Each time slot may contain a certain number (e.g., quantity) of symbols (e.g., Orthogonal Frequency Division Multiplexing (OFDM) symbols). In some embodiments, the number (e.g., quantity) of time slots in a subframe may depend on the parameter set. For a conventional cyclic prefix, a time slot may contain 14 symbols. For an extended cyclic prefix (e.g., applicable to a 60 kHz subcarrier spacing), a time slot may contain 12 symbols. The relationship between the number of symbols per time slot for the regular cyclic prefix and the extended cyclic prefix, the number of time slots per subframe, and the number of time slots per frame may depend on the parameter set. It should be understood that references to the first parameter set (e.g., μ=0) associated with the first subcarrier spacing (e.g., 15 kHz) may be used interchangeably between subframes and time slots.

[0056] In the wireless communication system 100, the electromagnetic (EM) spectrum can be divided into various categories, frequency bands, channels, etc., based on frequency or wavelength. For example, the wireless communication system 100 may support one or more operating frequency bands, such as frequency range names FR1 (410 MHz to 7.125 GHz), FR2 (24.25 GHz to 52.6 GHz), FR3 (7.125 GHz to 24.25 GHz), FR4 (52.6 GHz to 114.25 GHz), FR4a or FR4-1 (52.6 GHz to 71 GHz), and FR5 (114.25 GHz to 300 GHz). In some embodiments, NE 102 and UE 104 can perform wireless communication through one or more of the operating frequency bands. In some embodiments, FR1 can be used by NE 102 and UE 104, as well as other equipment or devices, for cellular communication services (e.g., control information, data). In some implementations, FR2 can be used by NE 102 and UE 104, as well as other equipment or devices, for short-range, high data rate capabilities.

[0057] FR1 may be associated with one or more parameter sets (e.g., at least three parameter sets). For example, FR1 may be associated with a first parameter set containing a 15 kHz subcarrier spacing (e.g., μ=0); a second parameter set containing a 30 kHz subcarrier spacing (e.g., μ=1); and a third parameter set containing a 60 kHz subcarrier spacing (e.g., μ=2). FR2 may be associated with one or more parameter sets (e.g., at least two parameter sets). For example, FR2 may be associated with a third parameter set containing a 60 kHz subcarrier spacing (e.g., μ=2); and a fourth parameter set containing a 120 kHz subcarrier spacing (e.g., μ=3).

[0058] According to the implementation scheme, NE 102 transmits CSI report settings associated with a set of RSs to UE 104. Furthermore, the CSI report settings include at least two sets of CSI report setting parameters: a first set of CSI report setting parameters corresponding to a first period of a first CSI measurement and for a first CSI report used in the BM (Bright Beam Report), and a second set of CSI report setting parameters corresponding to a second period of a second CSI measurement. UE 104 generates one or more CSI reports using event-triggered beam reports associated with the set of RSs and at least in part based on the at least two sets of CSI report setting parameters. UE 104 transmits one or more CSI reports to NE 102. NE 102 can use the one or more CSI reports for various purposes, such as for optimizing wireless communication with one or more UEs.

[0059] Referring to CSI reports in some wireless communication systems, the codebook report is divided into two parts based on the priority of the reported information, and each part is encoded. The following is a parameter list for the NR version 16 Type II codebook, including the content of the CSI report:

[0060] Part 1: Rank Indicator (RI) + Channel Quality Indicator (CQI) + Total Number of Coefficients

[0061] Part 2: Spatial Domain (SD) Basic Indicators + Frequency Domain (FD) Basic Indicators / Layer + Bitmap / Layer + Coefficient Amplitude Information / Layer + Coefficient Phase Information / Layer + Strongest Coefficient Indicator / Layer

[0062] Furthermore, the Type II CSI can be decomposed into sub-parts, each with a different priority (e.g., higher priority information listed first). This division allows the codebook size to be reported dynamically based on available resources in the uplink phase. Moreover, the Type II codebook is based on aperiodic CSI reporting and is reported in the PUSCH only via downlink control information (DCI) triggering (with one exception). The Type I codebook can be based on periodic CSI reporting (PUCCH), semi-persistent CSI reporting (PUSCH or PUCCH), or aperiodic reporting (PUSCH).

[0063] For some 2CSI priority reports, it should be noted that multiple CSI reports can be transmitted with different priorities, as shown in Table 1 below:

[0064] Table 1: Priority Reporting Levels for Some 2CSIs

[0065]

[0066] It should be noted that CSI reports can be prioritized based on the following:

[0067] 1. A CSI report set up for a specific cell may have higher priority than another CSI report set up for a different cell.

[0068] 2. CSI reports targeting one cell may have higher priority when compared to other CSI reports targeting another cell.

[0069] 3. CSI reports may have higher priority based on their content; for example, CSI reports carrying L1-RSRP information have higher priority.

[0070] 4. CSI reports may have higher priority based on their type, such as whether the CSI report is non-periodic, semi-persistent, or periodic, and whether the report is sent via PUSCH or PUCCH, which may affect the priority of the CSI report.

[0071] Therefore, CSI reports can be prioritized as follows, with CSI reports having higher priority if they have lower IDs.

[0072]

[0073] s CSI report settings index, and M s The maximum number of CSI reports set.

[0074] c Cell index, and N cells Number of service communities

[0075] k : 0 indicates a CSI report carrying L1-RSRP or L1-SINR, 1 indicates other CSI reports.

[0076] y: 0 indicates non-periodic reporting, 1 indicates semi-persistent reporting on PUSCH, 2 indicates semi-persistent reporting on PUCCH, and 3 indicates periodic reporting.

[0077] For CSI report triggering, the UE can use the CSI framework in NR version 15 to report network CSI information. The triggering mechanism between report settings and resource settings can be summarized in Table 2 below:

[0078] Table 2: Triggering Mechanisms Between Report Settings and Resource Settings

[0079]

[0080] Furthermore, the associated resource settings for CSI reporting will have the same time-domain behavior; once configured by RRC, it can be assumed that periodic CSI-RS / Interference Management (IM) resources and CSI reports exist and are active; non-periodic and semi-persistent CSI-RS / IM resources and CSI reports can be explicitly triggered or activated; non-periodic CSI-RS / IM resources and non-periodic CSI reports are triggered by transmitting DCI format 0-1 jointly; and semi-persistent CSI-RS / IM resources and semi-persistent CSI reports are activated independently.

[0081] Figure 2 This describes an implementation scheme 200 that defines a non-periodic triggering state for a CSI report setting list. For non-periodic CSI-RS / IM resources and non-periodic CSI reports, triggering can be performed jointly via transmission of DCI format 0-1. DCI format 0-1 contains a CSI request field (bits 0 to 6). A non-zero request field points to a so-called non-periodic triggering state configured by RRC (see Error! Reference source not found). A non-periodic triggering state is further defined as a list of up to 16 non-periodic CSI report settings, identified by a CSI report setting ID, for which the UE simultaneously calculates the CSI and transmits the CSI on the scheduled PUSCH transmission.

[0082] Figure 3 Explain the RRC configuration of NZP-CSI-RS / CSI-IM resources. Figure 4 Use 400 to illustrate the RRC configuration of NZP-CSI-RS resources, and Figure 5The RRC configuration for CSI-IM-Resource is illustrated using 500. For example, when a CSI reporting setting is associated with an aperiodic resource setting (which may contain multiple resource sets), the aperiodic NZP CSI-RS resource set for channel measurements, the aperiodic CSI-IM resource set (if used), and the aperiodic NZP CSI-RS resource set for IM (if used) are also included in the aperiodic trigger state definition for a given CSI reporting setting. For aperiodic NZP CSI-RS, the quasi-co-located (QCL) source to be used is also configured in the aperiodic trigger state. The UE may assume that the resources used for calculating channel and interference can be processed using the same spatial filter, for example, relative to "QCL-TypeD" quasi-co-located.

[0083] Table 3 summarizes the types of uplink channels used for CSI reporting based on CSI codebook types.

[0084] Table 1: Uplink Channels Used for CSI Reporting Based on CSI Codebook Type

[0085]

[0086] Figure 6 The 600 specification explains the partial CSI omission in version 15 of the PUSCH-based CSI. For example, for non-periodic CSI reports, the PUSCH-based report is divided into two CSI parts: CSI Part 1 and CSI Part 2. This can cause significant variations in the size of the CSI payload, and therefore the payload size design may result in high overhead. CSI Part 1 has a fixed payload size (and can be decoded by the gNB without prior information) and contains the following:

[0087] • RI (if reported), CRI (if reported), and CQI for the first codeword.

[0088] • The number of non-zero broadband amplitude coefficients per layer in the Type II CSI feedback on PUSCH.

[0089] CSI section 2 has a variable payload size, which can be derived from the CSI parameters in CSI section 1 and includes PMI and CQI with a second codeword when RI>4. For example, if three report settings x, y, and z are defined by the non-periodic trigger state indicated by DCI format 0_1, then the non-periodic CSI reports of CSI section 2 can be sorted as indicated by 600.

[0090] CSI reports can be prioritized based on the following:

[0091] 1. Time-domain behavior and physical channels, where more dynamic reports take precedence over less dynamic reports and PUSCH takes precedence over PUCCH.

[0092] 2. CSI content, in which beam reports (e.g., L1-RSRP reports) have higher priority than regular CSI reports.

[0093] 3. The serving cell corresponding to the CSI (in the case of carrier aggregation (CA) operation). The CSI corresponding to the PCcell has higher priority than the CSI corresponding to the Scell.

[0094] 4. reportConfigID.

[0095] When discussing antenna panels, antenna ports, quasi-co-location, Transmission Configuration Indication (TCI) status, spatial relationships, etc., the terms antenna, panel, and antenna panel are used interchangeably. An antenna panel can be hardware for transmitting and / or receiving radio signals at frequencies below 6 GHz (e.g., frequency range 1 (FR1)) or above 6 GHz (e.g., frequency range 2 (FR2)) or millimeter wave (mmWave). In some embodiments, the antenna panel may comprise an array of antenna elements, where each antenna element is connected to hardware such as a phase shifter, which allows a control module to apply spatial parameters to transmit and / or receive signals. The resulting radiation pattern may be referred to as a beam, which may or may not be single-peaked and allows the device to amplify signals transmitted or received from a spatial direction.

[0096] In some implementations, the antenna panel may or may not be virtualized as an antenna port in the specification. For each of the transmission (outbound) and reception (inbound) directions, the antenna panel can be connected to the baseband processing module via a radio frequency (RF) chain. The capabilities of the device may or may not be transparent to other devices in terms of the number of antenna panels, their duplex capability, their beamforming capability, etc. In some implementations, capability information may be transmitted via signaling, or in some implementations, capability information may be provided to the device without signaling. Where this information is available to other devices, it can be used for signaling or local decision-making.

[0097] In some implementations, the device (e.g., UE, node) antenna panel may be a physical or logical antenna array comprising a set of antenna elements or antenna ports sharing a common or essential part of the RF chain (e.g., in-phase / quadrature (I / Q) modulator, analog-to-digital (A / D) converter, local oscillator, phase-shift network). The device antenna panel, or “device panel,” may be a logical entity to which the physical device antennas are mapped. The mapping from physical device antennas to logical entities may vary depending on the device implementation. Communication (reception or transmission) on at least a subset of antenna elements or antenna ports that are effective for radiated energy of the antenna panel (also referred to herein as active elements) may involve biasing or energizing the RF chain, resulting in current consumption or power dissipation in the device associated with the antenna panel (including power amplifier / low-noise amplifier (LNA) power dissipation associated with the antenna elements or antenna ports). As used herein, the phrase “effective for radiated energy” is not intended to be limited to transmission functions but also covers reception functions. Therefore, antenna elements effective for radiated energy can be coupled simultaneously or sequentially to a transmitter to transmit radio frequency energy, or coupled to a receiver to receive radio frequency energy, or generally coupled to a transceiver to perform its intended functionality. Communication is achieved on the active elements of the antenna panel to generate radiation patterns or beams.

[0098] In some implementations, depending on the specific implementation of the device, the "device panel" may have at least one of the following functionalities: an antenna group unit for independently controlling its Tx beam, an antenna group unit for independently controlling its transmission power, and an antenna group unit for independently controlling its transmission timing. The "device panel" may be transparent to the gNB. Under certain conditions, the gNB or network may assume that the mapping between the device's physical antennas and the logical entity "device panel" is unlikely to change. For example, the conditions may include the period until the next update or report from the device, or the duration for which the gNB assumes the mapping is unlikely to change. The device may report its capabilities regarding the "device panel" to the gNB or network. Device capabilities may include at least the number of "device panels". In one implementation, the device may support UL transmission from one beam within the panel; for multiple panels, more than one beam (one beam per panel) may be available for UL transmission. In another implementation, more than one beam per panel may be supported / used for UL transmission.

[0099] In some of the described implementations, the antenna port is defined such that the channel transmitting a symbol on the antenna port can be inferred from the channel transmitting another symbol on the same antenna port.

[0100] If the large-scale properties of the channel transmitting symbols on one antenna port can be inferred from the channel transmitting symbols on the other antenna port, then the two antenna ports can be said to be quasi-co-located (QCL). Large-scale properties include one or more of delay spread, Doppler spread, Doppler shift, average gain, average delay, and spatial Rx parameters. The two antenna ports can be quasi-located relative to subsets of the large-scale properties, and different subsets of the large-scale properties can be indicated by the QCL type. The QCL type can indicate which channel properties are the same between the two RSs (e.g., on the two antenna ports). Therefore, RSs can be related to each other regarding what the UE can assume about its channel statistics or QCL properties. For example, the qcl-Type can take one of the following values:

[0101] -'QCL-TypeA': {Doppler frequency shift, Doppler spread, average delay, delay spread}

[0102] -'QCL-TypeB': {Doppler frequency shift, Doppler spread}

[0103] -'QCL-TypeC': {Doppler shift, average delay}

[0104] -'QCL-TypeD': {space Rx parameter}.

[0105] Spatial Rx parameters may include one or more of the following: Angle of Arrival (AoA), Main AoA, Average AoA, Angular Spread, Power Angle Spectrum (PAS) of AoA, Average AoD (Angle of Departure), PAS of AoD, Transmit / Receive Channel Correlation, Transmit / Receive Beamforming, Spatial Channel Correlation, etc.

[0106] QCL-TypeA, QCL-TypeB, and QCL-TypeC are applicable to all carrier frequencies, but QCL-TypeD may only be applicable to higher carrier frequencies (e.g., mmWave, FR2, and above), where the UE may not be able to perform omnidirectional transmission, for example, the UE may form a beam for directional transmission. In QCL-TypeD between two RS A and RS B, RS A is considered spatially co-located with RS B, and the UE may assume that RS A and B can be received using the same spatial filter (e.g., using the same receiver beamforming weights).

[0107] According to the implementation, an "antenna port" can be a logical port, which may correspond to a beam (generated by beamforming) or a physical antenna on the device. In some implementations, a physical antenna can be directly mapped to a single antenna port, where the antenna port corresponds to an actual physical antenna. Alternatively, after applying complex weights, cyclic delays, or both to the signal on each physical antenna, a set or subset of physical antennas, or an antenna set, antenna array, or antenna subarray can be mapped to one or more antenna ports. A physical antenna set may have antennas from a single module or panel, or from multiple modules or panels. Weights can be fixed, as in antenna virtualization schemes (e.g., cyclic delay diversity (CDD)). The process for deriving antenna ports from physical antennas can be specific to the device implementation and transparent to other devices.

[0108] In some of the described embodiments, the TCI state associated with the target transmission may indicate parameters used to configure the quasi-co-location relationship between the target transmission (e.g., the target RS of the demodulation reference signal (DM-RS) port of the target transmission during the transmission timing) and the source RS (e.g., synchronization block (SSB) / CSI-RS / sound reference signal (SRS)) relative to the quasi-co-location type parameters indicated in the corresponding TCI state. The TCI describes which RSs are used as QCL sources and which QCL properties can be derived from each RS. The apparatus may receive configurations of multiple transmission configuration indicator states of the serving cell for transmission on the serving cell. In some of the described embodiments, the TCI state includes at least one source RS to provide a reference (UE assumption) for determining the QCL and / or spatial filter.

[0109] In some of the described embodiments, spatial relationship information associated with the target transmission may indicate parameters for configuring the spatial settings between the target transmission and a reference RS (e.g., SSB / CSI-RS / SRS). For example, the apparatus may transmit the target transmission using the same spatial domain filter used to receive the reference RS (e.g., a downlink (DL) RS of an SSB / CSI-RS). In another instance, the apparatus may transmit the target transmission using the same spatial domain transmission filter used to transmit the reference RS (e.g., a UL RS of an SRS). The apparatus may receive configurations from multiple spatial relationship information configurations of the serving cell for transmission on the serving cell.

[0110] In some of the described implementations, if the device is configured with a separate DL / UL TCI via RRC signaling, then a UL TCI state is provided. The UL TCI state may include a source RS that provides a reference for determining UL spatial domain transmission filters for UL transmissions in or across a set of configured CCs / BWPs (e.g., PUSCH based on dynamic licensing / configuration licensing, dedicated PUCCH resources).

[0111] In some of the described implementations, if the device is configured with a joint DL / UL TCI via RRC signaling, a joint DL / UL TCI state is provided (e.g., the configuration of the joint TCI or individual DL / UL TCI is based on RRC signaling). The joint DL / UL TCI state refers to at least one common source reference RS used to determine both the DL QCL information and the UL spatial transmission filter. The source RS determined from the indicated joint (or common) TCI state provides a QCL Type-D indication (e.g., for device-specific physical downlink control channel (PDCCH) / physical downlink shared channel (PDSCH)) and is used to determine the UL spatial transmission filter for the CC or across a set of configured CC / BWPs (e.g., for UE-specific PUSCH / PUCCH). In one example, the UL spatial transmission filter is derived from an RS with DL QCL Type D in the joint TCI state. The spatial settings for UL transmission can be determined based on the spatial relationship of the reference source RS, which is configured with a qcl-Type set to 'typeD' in the joint TCI state.

[0112] Therefore, this disclosure provides a solution for event-triggered CSI feedback based on UE-assisted signaling. In the discussion herein, the following concepts are used interchangeably: network node, transmit-receive point (TRP), panel, antenna set, antenna port set, unified linear array, cell, node, radio head, communication (e.g., signal / channel) associated with a CORESET (control resource set) pool, and communication associated with a TCI state from a transmission configuration containing at least two TCI states. Hereinafter, a tracking reference signal (TRS) may correspond to an NZP CSI-RS resource set configured with the parameter 'trs-info'. A CSI-RS for beam management may correspond to a CSI-RS associated with an NZP CSI-RS resource set configured with the parameter 'repetition'. A CSI-RS for CSI corresponds to an NZP CSI-RS resource set that is neither configured with the parameter 'trs-info' nor with the parameter 'repetition'. A matrix can implicitly refer to a sequence of fields of arbitrary dimensions, an array (vector) of values, a standard 2D matrix, and more generally a Q-dimensional matrix (tensor), where Q ≥ 2 is an integer value. The terms "partial CSI update" and "event-triggered CSI report" are used interchangeably. The terms "complete CSI report" and "network-triggered CSI report" are used interchangeably. The terms "event-triggered" and "UE-assisted" are used interchangeably. For example, UE-assisted may refer to aspects related to the UE monitoring events that are not explicitly defined and for which a CSI report is triggered at least in part based on the occurrence of one or more of said events. The CSI framework and / or procedures most closely associated with 3GPP Rel-18 may be referred to as conventional behavior. Furthermore, the described embodiments and elements thereof can be combined in various ways.

[0113] The implementation includes aspects of CSI reporting triggered by a cycle 1 event. For example, in the first cycle of the CSI measurement and reporting framework, the network can configure the UE with CSI measurement and reporting corresponding to beam management parameters, and the UE transmits one or more CSI reports to the network. Several implementations are described below. Depending on the possible implementation, one or more elements or features from one or more of the described implementations may be combined.

[0114] In a first embodiment, the UE is configured with CSI reporting settings, which are associated with CSI resource settings that include a set of NZP CSI-RS resources for BM, SS / PBCH, or combinations thereof. In a first instance, the CSI reporting settings are associated with the number of reports containing at least one of 'CRI', 'SSBRI', 'L1-RSRP', and 'L1-SINR'. In a second instance, the CSI reporting settings are associated with CSI resource settings whose temporal behavior (e.g., resource type) is set to either periodic or semi-persistent, wherein the CSI resource settings are periodically associated with a first CSI resource. In a third instance, the CSI reporting settings are associated with a temporal behavior (e.g., report configuration type) set to either periodic or semi-persistent reporting, wherein the CSI reporting settings are periodically associated with a first CSI report.

[0115] In the second embodiment, the UE is configured with at least one CSI reporting setting, which includes two sets of CSI reporting setting parameters corresponding to CSI measurements and reporting for beam management. In the first example, the two sets of CSI reporting setting parameters correspond to two CSI reporting settings, wherein the first CSI reporting setting includes two CSI reporting setting IDs, the first CSI reporting setting ID corresponding to the identification of a first CSI reporting setting, and the second CSI reporting setting ID corresponding to the identification of a second CSI reporting setting associated with an event-triggered CSI report for beam management. In the second example, the two sets of CSI reporting setting parameters correspond to two CSI reporting sub-configurations, the first CSI reporting sub-configuration corresponding to a conventional CSI reporting setting, and the second CSI reporting sub-configuration corresponding to a second CSI reporting setting associated with an event-triggered CSI report for beam management.

[0116] The implementation includes aspects of CSI reporting triggered by a cycle 2 event. For example, in the second cycle of the CSI measurement and reporting framework, the network can configure the UE with CSI measurement and reporting corresponding to beam management parameters, and the transmission of one or more CSI reports by the UE can be conditional upon the occurrence of an event monitored at the UE. Several implementations are described below. According to the implementation, one or more elements and / or features from one or more of the described implementations can be combined.

[0117] In a first embodiment, the second set of CSI reporting settings parameters may correspond to a second period of CSI measurement and reporting, wherein the second period of CSI measurement and reporting follows the first period of CSI measurement and reporting used for BM. In a first instance, the second set of CSI reporting settings parameters is associated with the number of reports set to 'none'. In a second instance, the second set of CSI reporting settings parameters is associated with a second CSI reporting periodicity, wherein the value of the second CSI reporting periodicity is higher than the value of the first CSI reporting periodicity associated with the first set of CSI reporting parameters. In a third instance, the report configuration type of the CSI reports associated with the second set of CSI reporting settings parameters is the same as the report configuration type of the CSI reports associated with the second set of CSI reporting settings parameters.

[0118] In the fourth example, the number of reports associated with the second set of CSI report setting parameters is the same as the number of reports associated with the first set of CSI report setting parameters. In the fifth example, the second set of CSI report setting parameters is associated with the periodicity of a second CSI resource, and the periodicity value of the second CSI resource is greater than or equal to the periodicity value of the first CSI resource associated with the first set of CSI report setting parameters. In the sixth example, the resource type of the second CSI resource setting associated with the second set of CSI report setting parameters is the same as the resource type of the first CSI resource setting associated with the first set of CSI report setting parameters.

[0119] The implementation includes aspects of UE monitoring events for UE-assisted CSI reporting for BM. For example, when the UE is configured with event-triggered CSI measurement and reporting for BM, and the UE is within a second period of the CSI measurement and reporting framework, the UE can monitor a set of events defined by the network. For example, the monitoring of said set of events is based at least on CSI measurements taken during the second period of the CSI measurement and reporting framework. Several implementations are described below. According to the implementations, one or more elements or features from one or more of the described implementations can be combined.

[0120] In a first embodiment, at least one of the events in the set is based on the fact that a first L1-RSRP value of a selected beam measured (and reported) during a first period of the CSI measurement and reporting framework is at least a threshold greater than a second L1-RSRP value of the selected beam measured during a second period of the CSI measurement and reporting framework. In a first example, the selected beam corresponds to an NZPCSI-RS resource with an ID that is reported as a CRI value corresponding to a CSI report for the first period of the CSI measurement and reporting framework.

In a third instance, the threshold is configured by the network as part of a second set of CSI report setting parameters, for example, from a set of pre-configured thresholds.

In a first instance, the first beam corresponds to a first NZP CSI-RS resource with an ID having a first CRI value reported as a CSI report corresponding to the first period of the CSI measurement and reporting framework. In a second instance, the second beam corresponds to a second NZP CSI-RS resource with an ID having a second CRI value reported as a CSI report corresponding to the first period of the CSI measurement and reporting framework. In a third instance, the second beam corresponds to a second NZP CSI-RS resource with an ID not reported in a CSI report corresponding to the first period of the CSI measurement and reporting framework.

[0123] In the fourth example, the first beam corresponds to a first SS / PBCH resource with an ID that is reported as a first SSBRI value in a CSI report corresponding to the first period of the CSI measurement and reporting framework. In the fifth example, the second beam corresponds to a second SS / PBCH resource with an ID that is reported as a second SSBRI value in a CSI report corresponding to the first period of the CSI measurement and reporting framework.

In the seventh example, the threshold is configured by the network as a portion of a second set of CSI report setting parameters, for example, from a set of pre-configured thresholds.

[0124] In a fourth embodiment, at least one of the events in the set is based on the fact that a first L1-SINR value of a first beam measured (and reported) during a first period of the CSI measurement and reporting framework is at least one threshold smaller than a second L1-SINR value of a second beam measured during a second period of the CSI measurement and reporting framework.

In a second instance, the second beam corresponds to a second NZP CSI-RS resource with an ID having a second CRI value reported as a CSI report corresponding to the first period of the CSI measurement and reporting framework.

[0126] In a fifth embodiment, monitoring of at least one of the events in the set of events may be based on a time-limiting parameter. In a first instance, monitoring of at least one event is configured with a time limit for channel measurements, wherein the event is measured only based on the most recent, no later than, CSI reference resource, SS / PBCH, NZP CSI-RS, or a combination thereof associated with the CSI resource setting. In a second instance, monitoring of at least one event is not configured with a time limit for channel measurements, wherein the event is measured only based on SS / PBCH, NZP CSI-RS, or a combination thereof, no later than the CSI reference resource associated with the CSI resource setting.

[0127] In the third example, if the monitoring of at least one event is not configured with a time limit for channel measurements, then the number of SS / PBCH, NZP CSI-RS, or combinations thereof corresponding to the channel measurements is configured by the network.

[0128] The implementation includes aspects of a UE trigger signal corresponding to an event-triggered CSI report for BM. For example, a UE configured with event-triggered CSI measurement and reporting for BM can transmit an uplink (UL) UE trigger signal to the network when a subset of events from the set of events defined by the network occurs. Several implementations of the UE trigger signal are described below. According to the implementation, one or more elements or features from one or more of the described implementations can be combined.

[0129] In a first implementation, the UL UE trigger signal takes the form of a scheduling request (SR) signal. In a first instance, the SR signal is transmitted via PUCCH. In a second instance, the SR signal is transmitted via the UCI of PUSCH. In a third instance, the SR signal cannot be multiplexed with a CSI report or with a Hybrid Automatic Repeat Request Acknowledgment (HARQ-ACK) signal. In a fourth instance, the SR signal is associated with an event-triggered beam report, such as an SR on the UCI of PUCCH or PUSCH, where an identifier (e.g., SchedulingRequestID-EventTriggered-BM) indicates the configuration of the scheduling request, and the uplink resource allocation associated with the SR related to the event-triggered BM is set to "empty". In a fifth instance, the UE cancels the SR associated with the event-triggered BM after receiving a first signal from the network, the first signal corresponding to a new CSI report setting, for example, a DCI scheduling PUSCH triggered by an aperiodic CSI report setting.

[0130] In the second implementation, the UL UE trigger signal is in the form of a CSI report. In the first instance, the CSI report is transmitted via PUCCH. In the second instance, the CSI report is based on the number of reports associated with the event-triggered BM report. In the third instance, the number of reports associated with the event-triggered BM report is an independent number of reports; for example, the CSI report does not include other report numbers. In the fourth instance, the CSI report contains only one CSI report section.

[0131] In the sixth instance, the indication of the occurrence of a subset of events in the set of events associated with the event-triggered BM further includes the identification of the subset of events in the set of events associated with the event-triggered BM. In the seventh instance, the indication of the occurrence of a subset of events in the set of events associated with the event-triggered BM further includes the identification of NZPCSI-RS resources (e.g., CRI), the identification of SS / PBCH resources (e.g., SSBRI), or a combination thereof, wherein CRI or SSBRI or a combination thereof corresponds to a UE-recommended beam based on measurements taken during the second period of the CSI measurement and reporting framework. In the eighth instance, CSI reports are transmitted via configured resources, for example, based on configured authorization.

[0132] In the third implementation, the UL UE trigger signal is in the form of a UL report. In the first instance, the UL report is transmitted via PUCCH. In the second instance, the UL report is based on the number of reports associated with an event-triggered BM report. In the third instance, the UL report is associated with an event-triggered BM report. In the fourth instance, the indication of the occurrence of a subset of events in the set of events associated with the event-triggered BM further includes the identification of the subset of events in the set of events associated with the event-triggered BM. In the fifth instance, the indication of the occurrence of a subset of events in the set of events associated with the event-triggered BM further includes the identification of NZP CSI-RS resources (e.g., CRI), the identification of SS / PBCH resources (e.g., SSBRI), and / or combinations thereof. Furthermore, CRI and / or SSBRI, or combinations thereof, may correspond to a UE-recommended beam based on measurements taken during the second period of the CSI measurement and reporting framework. In the sixth instance, the UL report is transmitted via configured resources, for example, based on configured authorization.

[0133] The implementation also includes an updated BM report based on the UE trigger signal value. For example, a UE transmitting a UE trigger signal corresponding to CSI measurements and reports for BM event triggering can further transmit a second UL signal that includes additional BM reporting parameters compared to the UE trigger signal. Several implementations of the second UL signal are described below. According to the implementation, one or more elements or features from one or more of the described implementations can be combined.

[0134] In the first embodiment, the second UL signal corresponds to a CSI report. In the first instance, the CSI report is based at least on a first set of CSI report setting parameters. In the second instance, the CSI report is based on a second CSI report setting triggered after a UE trigger signal is received.

[0135] In a second embodiment, the second UL signal is a second CSI report containing differential parameter values ​​based on corresponding parameter values ​​in a first CSI report transmitted prior to the transmission of the UL trigger signal. In a first instance, the second CSI report corresponds to the number of reports associated with at least one of 'L1-RSRP' and 'L1-SINR', wherein the value of at least one of L1-RSRP or L1-SINR is differentially calculated based on the corresponding value in the first CSI report. In a second instance, the second CSI report contains the identification of a subset of events from the set of events associated with the event-triggered BM. In a third instance, the second CSI report contains values ​​associated with measurements corresponding to a subset of events from the set of events associated with the event-triggered BM, such as a decrease in the L1-RSRP value of the identified beam.

[0136] In the fourth example, the second CSI report includes the identification of NZP CSI-RS resources (e.g., CRI), the identification of SS / PBCH resources (e.g., SSBRI), or a combination thereof, where CRI or SSBRI or a combination thereof corresponds to the UE-recommended beam based on measurements taken during the second period of the CSI measurement and reporting framework. In the fifth example, the second CSI report is based on a non-periodic CSI report on the PUSCH.

[0137] In the third embodiment, the second UL signal is a contention-based UL resource report from a set of contention-based UL resource pools. In the first instance, the second UL signal is transmitted after at least a time period known to both the UE and the network (e.g., a configured value for the time period). In the second instance, each of the set of contention-based UL resource pools is identified by an index. In the third instance, the set of contention-based UL resource pools is based on contention-based resource allocation (CBRA) authorization.
