Description

TECHNICAL FIELD

[0001] The present disclosure relates generally to communication systems, and more particularly, to wireless communication systems with channel state information (CSI) reporting. BACKGROUND

[0002] Wireless communication systems are widely deployed to provide various telecommunication services such as telephony, video, data, messaging, and broadcasts. Typical wireless communication systems can employ multiple-access technologies capable of supporting communication with multiple users by sharing available system resources. Examples of such multiple-access technologies include code division multiple access (CDMA) systems, time division multiple access (TDMA) systems, frequency division multiple access (FDMA) systems, orthogonal frequency division multiple access (OFDMA) systems, single-carrier frequency division multiple access (SC-FDMA) systems, and time division synchronous code division multiple access (TD-SCDMA) systems.

[0003] These multiple access technologies have been adopted in various telecommunication standards to provide a common protocol that enables different wireless devices to communicate on a municipal, national, regional, and even global level. One example of a telecommunication standard is 5G New Radio (NR). 5G NR is part of a continuous mobile broadband evolution promulgated by Third Generation Partnership Project (3GPP) to meet new requirements associated with latency, reliability, security, scalability (e.g., with Internet of Things (IoT)), and other requirements. 5G NR includes services associated with enhanced mobile broadband (eMBB), massive machine type communications (mMTC), and ultra-reliable low latency communications (URLLC). Some aspects of 5G NR can be based on the 4G Long Term Evolution (LTE) standard. There exists a need for further improvements in 5G NR technology. These improvements can also be applicable to other multi-access technologies and the telecommunication standards that employ these technologies. SUMMARY

[0004] The following presents a simplified summary of one or more aspects in order to provide a basic understanding of such aspects. This summary is not an extensive overview of all contemplated aspects. It is not intended to identify key or critical elements of all aspects or to delineate the scope of any or all aspects. Its sole purpose is to present some concepts of one or more aspects in a simplified form as a prelude to the more detailed description that is presented later.

[0005] In one aspect of this disclosure, methods, computer-readable media, and apparatus are provided at a user equipment (UE). The apparatus may include at least one memory and at least one processor coupled to the at least one memory. At least partially based on information stored in the at least one memory, the at least one processor is configured, individually or in any combination, to receive downlink control information (DCI) from a network node, which triggers an aperiodic (AP) channel state information (CSI) report not associated with a measured channel measurement resource (CMR) or a measured interference measurement resource (IMR). In some aspects, at least partially based on information stored in the at least one memory, the at least one processor is configured, individually or in any combination, to receive downlink control information (DCI) from a network node, which triggers an aperiodic (AP) channel state information (CSI) report associated with a measured channel measurement resource (CMR) or a measured interference measurement resource (IMR), wherein one or more quantities to be included in the AP CSI report are based on one or more predicted targets separate from the measured CMR or the measured IMR. At least in part, based on information stored in the at least one memory, at least one processor is configured, individually or in any combination, to send AP CSI reports based on timeline adjustments associated with the AP CSI reports.

[0006] In another aspect of this disclosure, methods, computer-readable media, and apparatuses are provided at a network entity. The apparatus may include at least one memory and at least one processor coupled to the at least one memory. Based at least in part on information stored in the at least one memory, the at least one processor is configured, individually or in any combination, to transmit downlink control information (DCI) to a user equipment (UE) that triggers an aperiodic (AP) channel state information (CSI) report not associated with a measured channel measurement resource (CMR) or a measured interference measurement resource (IMR). In some aspects, based at least in part on information stored in the at least one memory, the at least one processor is configured, individually or in any combination, to transmit downlink control information (DCI) to a user equipment (UE) that triggers an aperiodic (AP) channel state information (CSI) report associated with a measured channel measurement resource (CMR) or a measured interference measurement resource (IMR), wherein one or more quantities to be included in the AP CSI report are based on one or more predicted targets separate from the measured CMR or the measured IMR. At least in part, based on information stored in the at least one memory, at least one processor is configured, either alone or in any combination, to obtain AP CSI reports.

[0030] The detailed description set forth below, in connection with the appended drawings and embodiments described herinin, provides a description of various configurations of the present disclosure. It should be noted that the concepts described herein can be practiced in a variety of configurations, and that the disclosure is not limited to only the specific configurations described herein. It should be further noted that the specific configurations set forth herein are provided for illustrative purposes, and are not intended to limit the concepts described herein to only the specific configurations set forth herein. Rather, the specific configurations set forth herein are provided to provide a thorough understanding of the concepts described herein.

[0031] Several aspects of telecommunication systems are presented with reference to various apparatus and methods. These apparatus and methods are described in the following detailed description and illustrated in the accompanying drawings by various blocks, components, circuits, processes, algorithms, etc. (collectively referred to as "elements"). These elements can be implemented with electronic hardware, computer software, or any combination thereof. Whether such elements are implemented as hardware or software depends on the particular application and design constraints imposed on the overall system.

[0032] By way of example, an element, or any portion of an element, or any combination of elements can be implemented as a "processing system" that includes one or more processors. A processor can be a microprocessor, microcontroller, graphics processing unit (GPU), central processing unit (CPU), application processor, digital signal processor (DSP), reduced instruction set computing (RISC) processor, system on a chip (SoC), baseband processor, field programmable gate array (FPGA), programmable logic device (PLD), state machine, gated logic, discrete hardware circuits, and other suitable hardware configured to perform the various functionality described throughout this disclosure. One or more processors in the processing system can execute software. Software shall be construed broadly to mean instructions, instruction sets, code, code segments, program code, programs, subprograms, software components, applications, software applications, software packages, routines, subroutines, objects, executables, threads of execution, procedures, functions, or any combination of them deemed useful by one of ordinary skill in the art, regardless of the particular computer-readable media on which the software can reside and / or be executed.

[0033] Thus, in one or more example aspects, implementations, and / or use cases, the described functions can be implemented in hardware, software, or any combination thereof. If implemented in software, the functions can be stored on or encoded as one or more instructions or code on a computer-readable medium. Computer-readable media includes computer storage media. Storage media can be any available media that can be accessed by a computer. By way of example, and not limitation, such computer-readable media can comprise a random-access memory (RAM), read-only memory (ROM), electrically erasable programmable ROM (EEPROM), optical disk storage, magnetic disk storage, other magnetic storage devices, combinations of the aforementioned types of computer-readable media, or any other medium that can be used to store computer executable code in the form of instructions or data structures that can be accessed by a computer.

[0034] While aspects, implementations and / or use cases described herein can be described in the context of 5G NR technology, aspects, implementations and / or use cases described herein can be implemented in the context of any suitable wireless communication technology, such as any NR technology, 3GPP UMTS Terrestrial Radio Access (UTRA), 4G Long Term Evolution (LTE), 5G NR, etc. NR is often discussed in the context of new radio access technologies for mobile communications, including 5G NR. NR can include a radio technology of frequency range 1 (FR1), which can utilize spectrum from 1 GHz to 24 GHz, as well as a radio technology of frequency range 2 (FR2), which can utilize spectrum from 24.25 GHz to 52.6 GHz. NR can be a 5G technology that utilizes OFDM with a cyclic prefix (CP) in the radio frequency spectrum (millimeter wave (mmW)) in addition to or instead of OFDM in other parts of the radio frequency spectrum. NR technology can include beamforming, massive MIMO (MIMO), and / or other technologies. LTE technology is often discussed in the context of 4G technology but can also be applicable to 5G technology. For further discussion of various 5G technologies, see 3GPP LTE, 5G NR, and Next Generation Communication Systems, edited by Chih-Lin I, John Wiley & Sons, 2018; 5G Networking: Services, Challenges and Vertical Applications, edited by Ahmad Rezaei Shahabad, John Wiley & Sons, 2018; and 5G Systems: Principles and Applications, edited by Jauvajeet Singh, John Wiley & Sons, 2018, which are incorporated by reference in their entirety.

[0035] Deployment of communication systems, such as 5G NR systems, can be arranged in a variety of ways with various components or constituent parts. In a 5G NR system or network, a network node, network entity, mobility element of a network, radio access network (RAN) node, core network node, network element, or network equipment, such as a base station (BS), or one or more units (or one or more components) performing base station functionality, can be implemented in an aggregated or disaggregated architecture. For example, a BS, such as a Node B (NB), an evolved NB (eNB), an NR BS, a 5G NB, an access point (AP), a transmission reception point (TRP), or a cell, etc., can be implemented as an aggregated base station (also referred to as a standalone BS or a monolithic BS) or a disaggregated base station.

[0036] A disaggregated base station can be configured to utilize a radio protocol stack that is physically or logically distributed among two or more units, such as one or more central or centralized units (CUs), one or more distributed units (DUs), or one or more radio units (RUs). In some aspects, a CU can be implemented within a RAN node, and one or more DUs can be co-located with the CU, or alternatively, can be geographically or virtually distributed in one or more other RAN nodes. The DUs can be implemented to be in communication with one or more RUs. Each of the CU, DU, and RU can be implemented as virtual units, i.e., a virtual central unit (VCU), virtual distributed unit (VDU), or virtual radio unit (VRU).

[0037] Base station operations or network designs can take into account the disaggregated nature of base station functionality. For example, a disaggregated base station can be utilized in an integrated access backhaul (IAB) network, an open radio access network (O-RAN (such as network configurations initiated by the O-RAN Alliance)), or a virtualized radio access network (vRAN, also referred to as a cloud radio access network (C-RAN)). Disaggregation can include distributing functionality across two or more units at various physical locations, as well as virtually distributing functionality of at least one unit, which can enable flexibility in network design. The various units of a disaggregated base station or disaggregated RAN architecture can be configured for wired or wireless communication with at least one other unit.

[0038] Aspects provided herein can enable reduced CSI-RS overhead, such as AP-CSI-RS overhead, UE power consumption, and CSI latency, via beam prediction. In some wireless communication systems, AP CSI reporting is associated with CMR / IMR. However, there can be a large number of beams, and different beams can be associated with different AP-CMRs (such as AP non-zero power (NZP)-CSI-RS), which can be significant overhead. Additionally, for a UE to measure the AP-CMR, the UE’s radio frequency (RF) components can be active, resulting in power consumption. Additionally, CSI latency can be significant due to having two reference symbols and reference symbols , in order to reduce CSI-RS overhead, UE power consumption, and CSI latency, aspects provided herein can provide triggering of CSI reporting (such as AP, P, or SP CSI reporting) without association to measured CMR or measured IMR.

[0039] Figure 1is a diagram 100 illustrating examples of wireless communication systems and access networks. The illustrated wireless communication systems include a disaggregated base station architecture. The disaggregated base station architecture can include one or more CUs 110 that can communicate directly with a core network 120 via a backhaul link, or indirectly with the core network 120 through one or more disaggregated base station units, such as a near real-time (near-RT) RAN intelligent controller (RIC) 125 via an E2 link, or a non-real-time (non-RT) RIC 115 associated with a service management and orchestration (SMO) framework 105, or both. The CUs 110 can communicate with one or more DUs 130 via respective midhaul links, such as Fl interfaces. The DUs 130 can communicate with one or more RUs 140 via respective front-haul links. The RUs 140 can communicate with respective UEs 104 via one or more radio frequency (RF) access links. In some implementations, a UE 104 can be simultaneously served by multiple RUs 140.

[0040] Each of the units (i.e., the CUs 110, the DUs 130, the RUs 140, and the near-RT RIC 125, the non-RT RIC 115, and the SMO framework 105) can include or be coupled to one or more interfaces configured to receive or transmit signals, data, or information (collectively, signals) via a wired or wireless transmission medium. Each of these units or an associated processor or controller providing instructions to the communication interfaces of these units can be configured to communicate with one or more of the other units via the transmission medium. For example, the units can include wired interfaces configured to receive or transmit signals to one or more of the other units over a wired transmission medium. Additionally, the units can include wireless interfaces that can include receivers, transmitters, or transceivers (such as RF transceivers) configured to receive or transmit signals to one or more of the other units over a wireless transmission medium, or both.

[0041] In some aspects, the CU 110 can host one or more higher layer control functions. Such control functions can include radio resource control (RRC), packet data convergence protocol (PDCP), service data adaptation protocol (SDAP), and / or the like. Each control function can be implemented with an interface configured to communicate signals with other control functions hosted by the CU 110. The CU 110 can be configured to handle user plane functionality (i.e., central unit-user plane (CU-UP)), control plane functionality (i.e., central unit-control plane (CU-CP)), or a combination thereof. In some implementations, the CU 110 can be logically split into one or more CU-UP units and one or more CU-CP units. When implemented in an O-RAN configuration, the CU-UP units can communicate bi-directionally with the CU-CP units via an interface, such as an El interface. The CU 110 can be implemented to communicate with the DUs 130 as needed for network control and signal transfer.

[0042] The DUs 130 can correspond to logical units that include one or more base station functions for controlling the operation of one or more RUs 140. In some aspects, the DUs 130 can host one or more of a radio link control (RLC) layer, a medium access control (MAC) layer, and one or more high physical (PHY) layers (such as modules for forward error correction (FEC) encoding and decoding, scrambling, modulation and demodulation, and / or the like) in accordance with a functional split, such as those defined by 3GPP. In some aspects, the DUs 130 can also host one or more low PHY layers. Each layer (or module) can be implemented with an interface configured to communicate signals with other layers (and modules) hosted by the DUs 130 or with control functions hosted by the CU 110.

[0043] The lower layer functionality can be implemented by one or more RUs 140. In some deployments, the RUs 140 controlled by the DUs 130 can correspond to logical nodes that host RF processing functions or low PHY layer functions (such as performing fast Fourier transform (FFT), inverse FFT (iFFT), digital beamforming, physical random access channel (PRACH) extraction and filtering, and / or the like) or both based at least in part on a functional split, such as a lower layer functional split. In such an architecture, the RUs 140 can be implemented to handle over-the-air (OTA) communications with one or more UEs 104. In some implementations, real-time and non-real-time aspects of control plane communications and user plane communications with the RUs 140 can be controlled by the corresponding DUs 130. In some scenarios, this configuration can enable the DUs 130 and the CUs 110 to be implemented in a cloud-based RAN architecture, such as a vRAN architecture.

[0044] The SMO framework 105 can be configured to support RAN deployment and orchestration of non-virtualized network elements and virtualized network elements. For non- virtualized network elements, the SMO framework 105 can be configured to support deployment of dedicated physical resources for RAN coverage requirements, which can be managed via an operations and maintenance interface, such as an Ol interface. For virtualized network elements, the SMO framework 105 can be configured to interact with a cloud computing platform, such as Open Cloud (O-Cloud) 190, to perform network element lifecycle management, such as to instantiate virtualized network elements, via a cloud computing platform interface, such as an 02 interface. Such virtualized network elements can include, but are not limited to, CUs 110, DUs 130, RUs 140, and near-RT RICs 125. In some implementations, the SMO framework 105 can communicate with hardware aspects of a 4G RAN, such as Open eNB (O-eNB) 111, via an Ol interface. Additionally, in some implementations, the SMO framework 105 can communicate directly with one or more RUs 140 via an Ol interface. The SMO framework 105 can also include a non-RT RIC 115 configured to support functionality of the SMO framework 105.

[0045] The non-RT RIC 115 can be configured to include logical functions that enable near real-time control and optimization of RAN elements and resources, artificial intelligence (AI) / machine learning (ML) (AI / ML) workflows including model training and updates, or policy-based direction of applications / features in the near-RT RIC 125. The non-RT RIC 115 can be coupled to or in communication with the near-RT RIC 125, such as via an Al interface. The near-RT RIC 125 can be configured to include logical functions that enable near real-time control and optimization of RAN elements and resources via data collection and actions through an interface, such as via an E2 interface, that connects one or more CUs 110, one or more DUs 130, or both, and an O-eNB with the near-RT RIC 125.

[0046] In some implementations, to generate AI / ML models to be deployed in the near-RT RIC 125, the non-RT RIC 115 can receive parameters or external enrichment information from an external server. Such information can be utilized by the near-RT RIC 125 and can be received at the SMO framework 105 or the non-RT RIC 115 from non-network data sources or from network functions. In some examples, the non-RT RIC 115 or the near-RT RIC 125 can be configured to tune RAN behavior or performance. For example, the non-RT RIC 115 can monitor long-term trends and patterns of performance and employ AI / ML models to perform corrective actions through the SMO framework 105, such as via reconfiguration of Ol, or through creation of RAN management policies, such as Al policies.

[0047] At least one of the CU 110, the DU 130, and the RU 140 can be referred to as a base station 102. Thus, the base station 102 can include one or more of the CU 110, the DU 130, and the RU 140, each component indicated in dashed line to represent that each component can or can not be included in the base station 102. The base station 102 provides wireless access to the core network 120 for the UEs 104. The base station 102 can include macro cells (high power cellular base stations) and / or small cells (low power cellular base stations). The small cells include femto cells, pico cells, and micro cells. Networks that include both small cells and macro cells can be referred to as heterogeneous networks. A heterogeneous network also can include home evolved node Bs (eNBs) (HeNBs), which can provide service to a restricted group known as a closed subscriber group (CSG). The communication links between the RUs 140 and the UEs 104 can include uplink (UL) (also referred to as reverse link) transmissions from a UE 104 to a RU 140 and / or downlink (DL) (also referred to as forward link) transmissions from a RU 140 to a UE 104. The communication links can use multiple-input and multiple-output (MIMO) antenna technology, including spatial multiplexing, beamforming, and / or transmit diversity. The communication links can be through one or more carriers, and each carrier can be a band of frequency waves having a predetermined Yx MHz ( x The base stations 102 / UEs 104 can use spectrum up to Y MHz (e.g., 5, 10, 15, 20, 100, 400, etc. MHz) bandwidth per carrier allocated in carrier aggregation. The carriers can or can not be adjacent to each other. The allocation of carriers can be asymmetric with respect to DL and UL (e.g., more or less carriers can be allocated for DL than for UL). The component carriers can include a primary component carrier and one or more secondary component carriers. A primary component carrier can be referred to as a primary cell (PCell) and a secondary component carrier can be referred to as a secondary cell (SCell).

[0048] Certain UEs 104 can communicate with each other using device-to-device (D2D) communication links 158. The D2D communication links 158 can use the DL / UL WWAN spectrum. The D2D communication links 158 can use one or more sidelink channels, such as a physical sidelink broadcast channel (PSBCH), a physical sidelink discovery channel (PSDCH), a physical sidelink shared channel (PSSCH), and a physical sidelink control channel (PSCCH). D2D communication can be through a variety of wireless D2D communications systems, such as for example, Bluetooth ™ (Bluetooth is a trademark of Bluetooth Special Interest Group (SIG)), Wi-Fi ™ (Wi-Fi is a trademark of Wi-Fi Alliance), LTE, or NR, based on the IEEE 802.11 standard.

[0049] The wireless communications system can also include a Wi-Fi AP 150 in communication with UEs 104 (also known as Wi-Fi stations (STAs)) via communication links 154, e.g., in 5 GHz unlicensed spectrum, and / or the like. When communicating in unlicensed spectrum, the UEs 104 / AP 150 can perform a clear channel assessment (CCA) prior to communicating to determine whether the channel is available.

[0050] The electromagnetic spectrum is often subdivided based on frequency / wavelength into various classes, bands, channels, and so forth. In 5G NR, two initial operating bands have been identified as frequency range designations FR1 (410 MHz to 7. 125 GHz) and FR2 (24.25 GHz to 52.6 GHz). Although a portion of FR1 is greater than 6 GHz, FR1 is often referred to (interchangeably) as a “sub-6 GHz” band in various documents and articles. A similar nomenclature issue sometimes occurs with respect to FR2, which is often (interchangeably) referred to as a “millimeter wave” band in documents and articles, despite the fact that FR2 is not in the extremely high frequency (EHF) band (30 GHz to 300 GHz) which is designated as a “millimeter wave” band by the International Telecommunications Union (ITU).

[0051] The frequencies between FR1 and FR2 are often referred to as mid-band frequencies. Recent 5G NR studies have identified operating bands for these mid-band frequencies as Frequency Range designation FR3 (7.125 GHz - 24.25 GHz). Bands that fall within FR3 can inherit FR1 and / or FR2 characteristics, and thus can effectively extend the features of FR1 and / or FR2 to mid-band frequencies. Moreover, higher bands are currently being explored to extend 5G NR operations beyond 52.6 GHz. For example, three higher operating bands have been identified as Frequency Range designations FR2-2 (52.6 GHz to 71 GHz), FR4 (71 GHz to 114.25 GHz), and FR5 (114.25 GHz to 300 GHz). Each of these higher bands falls within the EHF band.

[0052] With the above in mind, unless specifically stated otherwise, if the term “sub-6 GHz” or like term is used herein, this can broadly represent frequencies that can be less than 6 GHz, can be within FR1, or can include mid-band frequencies. Further, unless specifically stated otherwise, if the term “millimeter wave” or like term is used herein, this can broadly represent frequencies that can include mid-band frequencies, can be within FR2, FR4, FR2-2, and / or FR5, or can be within the EHF band.

[0053] The base stations 102 and the UEs 104 can each include multiple antennas (such as antenna elements, antenna panels, and / or antenna arrays) to facilitate beamforming. The base stations 102 can transmit to UEs 104 in one or more transmit directions 186 on the downlink 104. The UEs 104 can transmit to the base stations 102 in one or more transmit directions 188 on the uplink 106. The base stations 102 / UEs 104 can perform beam training to determine the best receive and transmit directions for each of the base stations 102 / UEs 104. The transmit and receive directions for the base stations 102 can or can not be the same. The transmit and receive directions for the UEs 104 can or can not be the same.

[0054] The base stations 102 can include and / or be referred to as gNBs, NodeBs, eNBs, access points, base transceiver stations, radio base stations, radio transceivers, transceiver functions, basic service sets (BSSs), extended service sets (ESSs), TRPs, network nodes, network entities, network equipment, or some other suitable terminology. The base stations 102 can be implemented as integrated access and backhaul (IAB) nodes, relay nodes, sidelink nodes, aggregated (monolithic) base stations with baseband units (BBUs) including CUs and DUs and RUs, or as disaggregated base stations including one or more of CUs, DUs, and / or RUs. A collection of base stations that can include disaggregated base stations and / or aggregated base stations can be referred to as a next generation (NG) RAN (NG-RAN).

[0055] The core network 120 can include an access and mobility management function (AMF) 161, a session management function (SMF) 162, a user plane function (UPF) 163, a unified data management (UDM) 164, one or more location servers 168, and other functional entities. The AMF 161 is a control node that handles signaling between the UEs 104 and the core network 120. The AMF 161 supports registration management, connection management, mobility management, and other functions. The SMF 162 supports session management and other functions. The UPF 163 supports packet routing, packet forwarding, and other functions. The UDM 164 supports generation of authentication and key agreement (AKA) credentials, user identification handling, access authorization, and subscription management. The one or more location servers 168 are illustrated as including a gateway mobile location center (GMLC) 165 and a location management function (LMF) 166. However, in general, the one or more location servers 168 can include one or more location / determination servers, which can include one or more of a GMLC 165, an LMF 166, a positioning determination entity (PDE), a serving mobile location center (SMLC), a mobile positioning center (MPC), and the like. The GMLC 165 and the LMF 166 support UE location services. The GMLC 165 provides an interface for clients / applications (e.g., emergency services) to access UE positioning information. The LMF 166 receives measurements and assistance information from the NG-RAN and the UE 104 via the AMF 161 to compute a position of the UE 104. The NG-RAN can utilize one or more positioning methods to determine a position of the UE 104. Positioning the UE 104 can involve signal measurements, position estimation, and optional velocity calculations based on these measurements. The signal measurements can be made by the UE 104 and / or the base stations 102 serving the UE 104. The measured signals can be based on one or more of a satellite positioning system (SPS) 170 (e.g., Global Navigation Satellite System (GNSS), Global Positioning System (GPS), Non-Terrestrial Network (NTN), or other satellite positioning / location system), LTE signals, Wireless Local Area Network (WLAN) signals, Bluetooth signals, Terrestrial Beacon System (TBS), sensor-based information (e.g., barometric pressure sensors, motion sensors), NR Enhanced Cell ID (NR E-CID) methods, NR signals (e.g., multi-round trip time (multi-RTT), DL angle of departure (DL-AoD), DL time difference of arrival (DL-TDOA), UL time difference of arrival (UL-TDOA), and UL angle of arrival (UL-AoA) positioning), and / or other systems / signals / sensors.

[0056] Examples of a UE 104 include a cellular phone, a smart phone, a session initiation protocol (SIP) phone, a laptop, a personal digital assistant (PDA), a satellite radio, a global positioning system, a multimedia device, a video device, a digital audio player (e.g., MP3 player), a camera, a game console, a tablet, a smart device, a wearable device, a vehicle, an electric meter, a gas pump, a large or small kitchen appliance, a healthcare device, an implant, a sensor / actuator, a display, or any other similar functional device. Some of the UEs 104 can be referred to as IoT devices (e.g., a parking meter, gas pump, toaster, vehicle, heart monitor, etc.). The UE 104 can also be referred to as a station, a mobile station, a subscriber station, a mobile unit, a subscriber unit, a wireless unit, a remote unit, a mobile device, a wireless device, a wireless communications device, a remote device, a mobile subscriber station, an access terminal, a mobile terminal, a wireless terminal, a remote terminal, a handset, a user agent, a mobile client, a client, or some other suitable terminology. In some scenarios, the term UE can also apply to one or more accessory devices such as in a device constellation arrangement. One or more of these devices can collectively or individually access a network.

[0057] Referring again to Figure 1 In some aspects, the UE 104 can include a CSI component 198. In some aspects, the CSI component 198 can be configured to receive, from a network node, downlink control information (DCI) that triggers an aperiodic (AP) channel state information (CSI) report that is not associated with a measured channel measurement resource (CMR) or a measured interference measurement resource (IMR). In some aspects, the CSI component 198 can be further configured to receive, from the network node, DCI that triggers an AP CSI report that is associated with the measured CMR or the measured IMR, where one or more quantities to be included in the AP CSI report are based on one or more prediction targets that are separate from the measured CMR or the measured IMR. In some aspects, the CSI component 198 can be further configured to transmit the AP CSI report based on a timeline adjustment associated with the AP CSI report.

[0058] In certain aspects, the base station 102 can include a CSI component 199. In some aspects, the CSI component 199 can be configured to transmit, for a UE, DCI that triggers an AP CSI report that is not associated with a measured CMR or a measured IMR. In some aspects, the CSI component 199 can be further configured to transmit, for a UE, DCI that triggers an AP CSI report that is associated with a measured CMR or a measured IMR, where one or more quantities to be included in the AP CSI report are based on one or more prediction targets that are separate from the measured CMR or the measured IMR. In some aspects, the CSI component 199 can be further configured to obtain the AP CSI report.

[0059] While the following description can focus on 5G NR, the concepts described herein can be applicable to other similar areas, such as LTE, LTE-A, CDMA, GSM, and other radio access technologies.

[0060] As described herein, a node (which can be referred to as a node, network node, network entity, or wireless node) can include, be, or can be included in (e.g., as a component of) a base station (e.g., any of the base stations described herein), a UE (e.g., any of the UEs described herein), a network controller, an apparatus, a device, a computing system, an integrated access and backhaul (IAB) node, a distributed unit (DU), a central unit (CU), a remote / radio unit (RU) (which can also be referred to as a remote radio unit (RRU)), and / or another processing entity configured to perform any of the techniques described herein. For example, a network node can be a UE. For another example, a network node can be a base station or network entity. For yet another example, a first network node can be configured to communicate with a second network node or a third network node. In one aspect of this example, the first network node can be a UE, the second network node can be a base station, and the third network node can be a UE. In another aspect of this example, the first network node can be a UE, the second network node can be a base station, and the third network node can be a base station. In yet other aspects of this example, the first network node, the second network node, and the third network node can be different with respect to these examples. Similarly, a reference to a UE, a base station, an apparatus, a device, a computing system, etc. can include the disclosure of a UE, a base station, an apparatus, a device, a computing system, etc. as a network node. For example, the disclosure of a UE configured to receive information from a base station also discloses a first network node configured to receive information from a second network node. Once a particular example is extended in accordance with the present disclosure (e.g., the disclosure of a UE configured to receive information from a base station also discloses a first network node configured to receive information from a second network node), the broader example of the narrower example can be interpreted in reverse, but in a broad, open-ended fashion. In the above example in which the disclosure of a UE configured to receive information from a base station also discloses a first network node configured to receive information from a second network node, the first network node can refer to a first UE, a first base station, a first apparatus, a first device, a first computing system, a first set of one or more components, a first processing entity, etc. configured to receive the information; and the second network node can refer to a second UE, a second base station, a second apparatus, a second device, a second computing system, a second set of one or more components, a second processing entity, etc.

[0061] As described herein, different terminology can be used in various aspects to describe the communication of information (e.g., any information, signals, and / or the like). The disclosure of one communication term includes the disclosure of other communication terms. For example, a first network node can be described as being configured to transmit information to a second network node. In this example and consistent with the disclosure, the disclosure of the first network node being configured to transmit information to the second network node includes the disclosure of the first network node being configured to provide, deliver, output, communicate, or send information to the second network node. Similarly, in this example and consistent with the disclosure, the disclosure of the first network node being configured to transmit information to the second network node includes the disclosure of the second network node being configured to receive, obtain, or decode the information provided, delivered, output, communicated, or sent by the first network node.

[0062] Figure 2A FIG. 200 is a diagram 200 illustrating an example of a first subframe within a 5G NR frame structure. Figure 2B FIG. 230 is a diagram 230 illustrating an example of DL channels within a 5G NR subframe. Figure 2C FIG. 250 is a diagram 250 illustrating an example of a second subframe within a 5G NR frame structure. Figure 2D FIG. 280 is a diagram 280 illustrating an example of UL channels within a 5G NR subframe. The 5G NR frame structure can be frequency division duplex (FDD) in which Figure 2A 、 Figure 2C In the examples provided, the 5G NR frame structure is assumed to be TDD, where subframe 4 is configured with slot format 28 (with mostly DL), where D is DL, U is UL, and F is flexible to use between DL / UL, and subframe 3 is configured with slot format 1 (with all UL). While subframes 3, 4 are shown with slot formats 1, 28, respectively, any particular subframe can be configured with any of the various available slot formats 0-61. Slot formats 0, 1 are all DL, UL, respectively. Other slot formats 2-61 include a mix of DL, UL, and flexible symbols. UEs are configured with a slot format (dynamically through DL control information (DCI) or semi-statically / statically through radio resource control (RRC) signaling) through a received slot format indicator (SFI). Note that the following description also applies for 5G NR frame structures that are TDD.

[0063] Figure 2A to Figure 2DA frame structure is illustrated, and aspects of the disclosure can be applicable to other wireless communication technologies that can have different frame structures and / or different channels. One frame (10 ms) can be divided into 10 equal sized subframes (1 ms). Each subframe can include one or more slots. A subframe can also include mini-slots, which can contain 7, 4, or 2 symbols. Each slot can include 14 or 12 symbols depending on whether a cyclic prefix (CP) is normal or extended. For a normal CP, each slot can include 14 symbols, and for an extended CP, each slot can include 12 symbols. Symbols on the DL can be CP-orthogonal frequency division multiplexing (OFDM) (CP-OFDM) symbols. Symbols on the UL can be CP-OFDM symbols (for high throughput scenarios) or discrete Fourier transform (DFT)-spread-OFDM (DFT-s-OFDM) symbols (for power-limited scenarios; limited to single-stream transmission). The number of slots within a subframe is based on the CP and the numerology. The numerology defines the subcarrier spacing (SCS) (see Table 1). The symbol length / duration can scale with 1 / SCS. Table 1: Parameter sets, SCS and CP

[0064] For a normal CP (14 symbols / slot), different numerologies m 0 to 4 allow for 1, 2, 4, 8, and 16 slots per subframe, respectively. For an extended CP, numerology 2 allows for 4 slots per subframe. Thus, for a normal CP and numerology m, there are 14 symbols / slot and 2 µ slots / subframe. The subcarrier spacing can be equal to where is the numerology 0 to 4. Thus, the subcarrier spacing for numerology m = 0 is 15 kHz, and the subcarrier spacing for numerology m = 4 is 240 kHz. The symbol length / duration is inversely related to the subcarrier spacing. Figure 2A to Figure 2D An example of a normal CP with 14 symbols per slot and numerology m = 2 with 4 slots per subframe is provided. The slot duration is 0.25 ms, the subcarrier spacing is 60 kHz, and the symbol duration is approximately 16.67 ps. Within a frame collection, there can be one or more different bandwidth parts (BWPs) that are frequency division multiplexed (see Figure 2B ). Each BWP can have a particular numerology and CP (normal or extended).

[0065] A resource grid can be used to represent the frame structure. Each time slot includes a resource block (RB) (also referred to as a physical RB (PRB)) that extends 12 consecutive subcarriers. The resource grid is divided into multiple resource elements (REs). The number of bits carried by each RE depends on the modulation scheme.

[0066] As Figure 2A illustrated, some of the REs carry reference (pilot) signals (RS) for the UE. The RS can include demodulation RS (DM-RS) (indicated as R for one particular configuration, but other DM-RS configurations are possible) and channel state information reference signals (CSI-RS) for channel estimation at the UE. The RS can also include beam measurement RS (BRS), beam refinement RS (BRRS), and phase tracking RS (PT-RS).

[0067] Figure 2B An example of various DL channels are illustrated. The physical downlink control channel (PDCCH) carries DCI within one or multiple control channel elements (CCEs) (e.g., 1, 2, 4, 8, or 16 CCEs), each CCE including six RE groups (REGs), each REG including 12 consecutive REs in an OFDM symbol of an RB. A PDCCH within one BWP can be referred to as a control resource set (CORESET). A UE is configured to monitor PDCCH candidates in a PDCCH search space (e.g., common search space, UE-specific search space) during PDCCH monitoring occasions on the CORESET, where the PDCCH candidates have different DCI formats and different aggregation levels. Additional BWPs can be located at greater and / or lower frequencies on the channel bandwidth. A primary synchronization signal (PSS) can be within symbol 2 of particular subframes of a frame. The PSS is used by a UE 104 to determine subframe / symbol timing and physical layer identity. A secondary synchronization signal (SSS) can be within symbol 4 of particular subframes of a frame. The SSS is used by a UE to determine physical layer cell identity group number and radio frame timing. Based on the physical layer identity and the physical layer cell identity group number, the UE can determine a physical cell identifier (PCI). Based on the PCI, the UE can determine the locations of DM-RS. The physical broadcast channel (PBCH), which carries a master information block (MIB) that provides system bandwidth and a

[0068] As Figure 2CSome of the REs carry DM-RS (indicated by R for one particular configuration, but other DM-RS configurations are possible) for channel estimation at the base station. The UE can transmit DM-RS for the physical uplink control channel (PUCCH) and DM-RS for the physical uplink shared channel (PUSCH). The PUSCH DM-RS can be transmitted in the first one or two symbols of the PUSCH. The PUCCH DM-RS can be transmitted in different configurations depending on whether short or long PUCCHs are transmitted and depending on the particular PUCCH format used. The UE can transmit sounding reference signals (SRS). The SRS can be transmitted in the last symbol of a subframe. The SRS can have a comb- type structure, and a UE can transmit SRS on one of the combs. The SRS can be used by a base station for channel quality estimation to enable frequency-dependent scheduling for the UL.

[0069] Figure 2D Examples of various UL channels within a subframe of a frame are illustrated. The PUCCH can be located as indicated in one configuration. The PUCCH carries uplink control information (UCI), such as scheduling requests, a channel quality indicator (CQI), a precoding matrix indicator (PMI), a rank indicator (RI), and hybrid automatic repeat request (HARQ) acknowledgment (ACK) (HARQ-ACK) feedback (i.e., one or more HARQ ACK bits indicating one or more ACKs and / or negative ACKs (NACKs)). The PUSCH carries data, and can additionally be used to carry buffer status reports (BSRs), power headroom reports (PHRs), and / or UCI.

[0070] Figure 3is a block diagram of the base station 310 in communication with the UE 350 in an access network. In the DL, Internet Protocol (IP) packets can be provided to a controller / processor 375. The controller / processor 375 implements layer 3 and layer 2 functionality. Layer 3 includes a radio resource control (RRC) layer, and layer 2 includes a service data adaptation protocol (SDAP) layer, a packet data convergence protocol (PDCP) layer, a radio link control (RLC) layer, and a medium access control (MAC) layer. The controller / processor 375 provides RRC layer functionality associated with broadcasting of system information (e.g., MIB, SIBs), RRC connection control (e.g., RRC connection paging, RRC connection establishment, RRC connection modification, and RRC connection release), inter radio access technology (RAT) mobility, and measurement configuration associated with a serving cell and a neighbor cell; PDCP layer functionality associated with header compression / decompression, security (ciphering, deciphering, integrity protection, integrity verification), and handover support functions; RLC layer functionality associated with the transfer of upper layer packet data units (PDUs), error correction through ARQ, concatenation, segmentation, and reassembly of upper layer SDUs, re-segmentation of RLC data PDUs, and reordering of RLC data PDUs; and MAC layer functionality associated with mapping between logical channels and transport channels, multiplexing / de-multiplexing of MAC SDUs onto / from transport blocks (TBs), scheduling information reporting, error correction through HARQ, priority handling, and logical channel prioritization.

[0071] Transmit (TX) processor 316 and receive (RX) processor 370 implement Layer 1 functionality associated with various signal processing functions. Layer 1 (which includes the physical (PHY) layer) may include error detection on the transport channel, forward error correction (FEC) decoding / decoding of the transport channel, interleaving, rate matching, mapping to the physical channel, modulation / demodulation of the physical channel, and MIMO antenna processing. TX processor 316 processes the mapping to the signal constellation based on various modulation schemes (e.g., binary phase shift keying (BPSK), quadrature phase shift keying (QPSK), M-order phase shift keying (M-PSK), M-order quadrature amplitude modulation (M-QAM)). The decoded and modulated symbols can then be divided into parallel streams. Each stream can then be mapped to OFDM subcarriers, multiplexed with a reference signal (e.g., a pilot) in the time and / or frequency domains, and then combined using inverse fast Fourier transform (IFFT) to produce a physical channel carrying a stream of time-domain OFDM symbols. The OFDM stream undergoes spatial pre-decoding to generate multiple spatial streams. Channel estimates from channel estimator 374 can be used to determine decoding and modulation schemes, as well as for spatial processing. Channel estimates can be derived from reference signals and / or channel condition feedback transmitted by UE 350. Each spatial stream can then be provided to a different antenna 320 via a separate transmitter 318Tx. Each transmitter 318Tx can utilize the corresponding spatial stream to modulate a radio frequency (RF) carrier for transmission.

[0072] At UE 350, each receiver 354Rx receives signals via its corresponding antenna 352. Each receiver 354Rx recovers the information modulated onto the RF carrier and provides that information to the receive (RX) processor 356. The TX processor 368 and RX processor 356 implement Layer 1 functionality associated with various signal processing functions. The RX processor 356 can perform spatial processing on the information to recover any spatial stream destined for UE 350. If multiple spatial streams are destined for UE 350, the RX processor 356 can combine them into a single OFDM symbol stream. The RX processor 356 then uses a Fast Fourier Transform (FFT) to transform the OFDM symbol stream from the time domain to the frequency domain. The frequency domain signal consists of a separate OFDM symbol stream for each subcarrier of the OFDM signal. The symbols on each subcarrier, along with the reference signal, are recovered and demodulated by determining the most probable signal constellation points transmitted by base station 310. These soft decisions can be based on a channel estimate calculated by channel estimator 358. The soft decision is then decoded and deinterleaved to recover the data and control signals originally transmitted by base station 310 on the physical channel. The data and control signals are then provided to controller / processor 359, which implements layer 3 and layer 2 functionality.

[0073] The controller / processor 359 can be associated with a memory 360 that stores program codes and data. The memory 360 can be referred to as a computer-readable medium. In the UL, the controller / processor 359 provides demultiplexing between transport and logical channels, packet reassembly, deciphering, header decompression, and control signal processing to recover IP packets from the core network. The controller / processor 359 is also responsible for error detection using an ACK and / or NACK protocol to support HARQ operations.

[0074] Similar to the functionality described in connection with the DL transmission by the base station 310, the controller / processor 359 provides RRC layer functionality associated with system information (e.g., MIB, SIBs) acquisition, RRC connections, and measurement reporting; PDCP layer functionality associated with header compression / decompression, and security (ciphering, deciphering, integrity protection, integrity verification); RLC layer functionality associated with the transfer of upper layer PDUs, error correction through ARQ, concatenation, segmentation, and reassembly of RLC SDUs, re-segmentation of RLC data PDUs, and reordering of RLC data PDUs; and MAC layer functionality associated with mapping between logical channels and transport channels, multiplexing of MAC SDUs onto TBs, demultiplexing of MAC SDUs from TBs, scheduling information reporting, error correction through HARQ, priority handling, and logical channel prioritization.

[0075] The TX processor 368 can use channel estimates derived by the channel estimator 358 from a reference signal or feedback transmitted by the base station 310 to select the appropriate coding and modulation schemes and to facilitate spatial processing. The spatial streams generated by the TX processor 368 are provided to the different antenna 352 via separate transmitters 354. Each transmitter 354 modulates an RF carrier with a respective spatial stream for transmission.

[0076] The UL transmission is processed at the base station 310 in a manner similar to that described in connection with the receiver function at the UE 350. Each receiver 318 receives a signal through its respective antenna 320. Each receiver 318 recovers information modulated onto an RF carrier and provides the information to a RX processor 370.

[0077] The controller / processor 375 can be associated with a memory 376 that stores program codes and data. The memory 376 can be referred to as a computer-readable medium. In the UL, the controller / processor 375 provides demultiplexing between transport and logical channels, packet reassembly, deciphering, header decompression, control signal processing to recover IP packets from the core network. The controller / processor 375 is also responsible for error detection using an ACK and / or NACK protocol to support HARQ operations.

[0078] At least one of the TX processor 368, the RX processor 356, and the controller / processor 359 can be configured to perform aspects in connection with the CSI component 198. Figure 1 At least one of the TX processor 368, the RX processor 356, and the controller / processor 359 can be configured to perform aspects in connection with the CSI component 198.

[0079] At least one of the TX processor 316, the RX processor 370, and the controller / processor 375 can be configured to perform aspects in connection with the CSI component 199. Figure 1 At least one of the TX processor 316, the RX processor 370, and the controller / processor 375 can be configured to perform aspects in connection with the CSI component 199.

[0080] Figure 4 is a diagram 400 illustrating example beam management (BM). As Figure 4Illustratively, at 410, the UE can be in an RRC inactive state or an RRC idle state, and a tracking reference signal (TRS) can be configured for the UE for the RRC inactive state or the RRC idle state. At 420, the UE can perform an initial access with a network node. During the initial access, there can be SSB (wide) beam sweeping, and the initial access at 410 can be a contention-based random access (CBRA) with a random access preamble and a PRACH occasion (RO) associated with an SSB. Once a connection is established and the UE enters an RRC connected state, at 430, BM in the RRC connected state can be performed. There can be different types of BM that can coexist. In a first type of BM, which can be based on various downlink beam management mechanisms, the various downlink beam management mechanisms can include: (1) beam selection (which can be referred to as “P1”), (2) beam refinement for a transmitter (network node transmitter) (which can be referred to as “P2”), or (3) beam refinement for a receiver (UE reception) (which can be referred to as “P3”). For P1, the network node can sweep TRP beams, and the UE sweeps UE beams and selects and reports a best beam (e.g., a best TRP beam measured by a best UE beam) to the network node. For P2, the network node can refine beams (e.g., sweep narrower beams over a narrower range), and the UE detects a best beam and reports it to the network node. For P3, the network node can fix a beam (repeating the same beam), and the UE refines its receiver beam. P3 can set a spatial filter on a receiver antenna array, and can be used to facilitate UE beamforming. Each of P1, P2, or P3 can be based on an SSB or a CSI-RS. The first type of BM can be further based on various uplink beam management mechanisms, which can include: (1) beam selection (which can be referred to as “U1”), (2) beam refinement for a transmitter (UE transmission) (which can be referred to as “U2”), or (3) beam refinement for a receiver (network node receiver) (which can be referred to as “U3”). The first type of BM can be further based on layer 1 (L1) reference signal received power (RSRP) reporting and transmission configuration indicator (TCI) state configuration and indication. There can be a second type of BM, which can be referred to as “eBM,” that can be based on L1 signal to interference and noise ratio (SINR) reporting, and can facilitate overhead and latency reduction based on component carrier (CC) group beam updates and faster UL beam updates. There can be a third type of BM, which can be referred to as “FeBM.” FeBM can further enhance latency reduction and efficiency through the use of unified TCI states, L1 / layer 2 (L2) mobility, dynamic TCI updates, UL multi-panel selection, maximum permissible exposure (MPE) mitigation, and other BM latency reduction techniques.FeBM can facilitate single frequency network (SFN) or high speed train (HST), and can facilitate BM for multi-TRP.

[0081] Beam failure can occur. To detect beam failure, beam failure detection (BFD) can be performed based on measurements of various BFD RS. Once beam failure is detected, at 440, beam failure recovery (BFR) can be performed. To facilitate BFD and BFR of a primary cell (PCell) or a primary secondary cell (PSCell), BFD can be based on BFD RS and PDCCH block error rate (BLER), and BFR can be based on contention-free random access (CFRA). To facilitate BFD and BFR of a secondary cell (SCell), link recovery request via scheduling request (SR) and BFR based on medium access control (MAC) control element (MAC-CE) can be used. If beam failure recovery is unsuccessful, the UE can enter radio link failure at 450.

[0082] As an example of L1 / L2 mobility, inter-cell beam management based on beam-based mobility can be facilitated by L1 and / or L2 signaling, such as UE-specific channels / RSs, which can be associated with switching to a TRP with a different PCI according to unified TCI update based on downlink control information (DCI) or medium access control (MAC) control element (MAC-CE).

[0083] In some aspects, a network can configure a set of cells for L1 / L2 mobility. This set of cells for L1 / L2 mobility can be referred to as a L1 / L2 mobility configured cell set. A subset of the L1 / L2 mobility configured cell set can be activated (e.g., with L1 or L2 control signaling) and can be referred to as a L1 / L2 mobility activated cell set (which can also be referred to as a L1 / L2 activated mobility cell set). A subset of cells in the L1 / L2 mobility configured cell set that are not activated or indicated to be deactivated can be referred to as a L1 / L2 mobility deactivated cell set or a deactivated L1 / L2 mobility cell set. The L1 / L2 mobility activated cell set can be a set of cells in the L1 / L2 mobility configured cell set that are activated and can readily be used for data and control transfer. The L1 / L2 mobility deactivated cell set (which can be a L1 / L2 mobility candidate cell set) can be a set of cells in the configured set that are configured for the UE that are yet deactivated (e.g., not used for data / control transfer until activated) and can be activated by L1 / L2 signaling. Once activated, the deactivated cells can be used for data and control transfer between the UE and the base station. L1 / L2 inter-cell mobility can reduce mobility latency. The configuration and maintenance of multiple candidate cells can allow for faster application of the configured candidate cells and the activated set of cells can provide for dynamic switching between candidate serving cells (e.g., including SpCell and SCells) based on L1 or L2 signaling.

[0084] The procedures for L1 / L2 based inter-cell mobility apply to many scenarios. These scenarios can include standalone CA and NR-DC cases where the serving cell changes within one CG, intra-DU and intra-CU inter-DU cases (applicable to standalone and CA where new RAN interface is not expected), intra- and inter- frequency cases, FR1 and FR2 cases. In these scenarios, the source cell and target cell can be synchronized or non-synchronized.

[0085] For mobility management of the active cell set, L1 / L2 signaling can be used to activate / deactivate cells in the L1 / L2 mobility configured cell set and select beams within the active cells (of the active cell set). As the UE moves, cells from the L1 / L2 mobility configured cell set can be deactivated and activated by L1 / L2 signaling based on signal quality (e.g., based on measurements), load, etc. Example measurements can include cell coverage measurements represented by a radio signal received power (RSRP) and quality represented by a radio signal received quality (RSRQ), or other measurements performed by the UE on signals from the base station. In some aspects, these measurements can be L1 measurements, such as one or more of RSRP, RSRQ, received signal strength indicator (RSSI), or signal-to-noise-and-interference ratio (SINR) measurements of various signals such as SSB, PSS, SSS, broadcast channel (BCH), DM-RS, CSI-RS, etc.

[0086] In some aspects, all cells in the L1 / L2 mobility configured cell set can belong to the same DU, and these cells can be on the same or different carrier frequencies. The cells in the L1 / L2 mobility configured cell set can cover a mobility area.

[0087] As an example of unified TCI states, a joint DL / UL TCI state pool can be used for joint DL / UL TCI state updates for beam indication. In some aspects, the joint TCI can or can not include UL specific parameters such as UL PC / timing parameters, PL RS, panel related indication, etc. If the joint TCI includes UL specific parameters, these parameters can be used for UL transmissions among the DL and UL transmissions to which the joint TCI applies.

[0088] Under the unified TCI framework, different types of common TCI states can be indicated. For example, Type 1 TCI can be a joint DL / UL common TCI state to indicate a common beam for at least one DL channel or RS and at least one UL channel or RS. Type 2 TCI can be a separate DL (e.g., separate from UL) common TCI state to indicate a common beam for more than one DL channel or RS. Type 3 TCI can be a separate UL common TCI state to indicate a common beam for more than one UL channel / Rs. Type 4 TCI can be a separate DL single channel or RS TCI state to indicate a beam for a single DL channel or RS. Type 5 TCI can be a separate UL single channel or RS TCI state to indicate a beam for a single UL channel or RS. Type 6 TCI can include UL spatial relation information (e.g., such as a sounding reference signal (SRS) resource indicator (SRI)) to indicate a beam for a single UL channel or RS. Example RSs can be SSB, tracking reference signal (TRS) and associated CSI-RS for tracking, CSI-RS for beam management, CSI-RS for CQI management, DM-RS associated with non-UE specific reception on PDSCH, and a subset of control resource set (CORESET) (which can be the full set), etc. A TCI state can be defined to represent at least one source RS to provide a reference (e.g., UE assumption) for determining a quasi co-location (QCL) or spatial filter. For example, a TCI state can define a QCL assumption between a source RS and a target RS.

[0089] To facilitate beam management, such as beam prediction in time or spatial domain for overhead and latency reduction, beam selection accuracy improvement, etc., artificial intelligence (AI) or machine learning (ML) models can be used. For lifecycle management of BM AI / ML models, model training, model deployment, model inference, model monitoring, and model updating can be performed.

[0090] For AI / ML model based BM, there can be spatial domain DL beam prediction of a beam set A based on measurement results of a beam set B, or time DL beam prediction of a beam set A based on historical measurement results of a beam set B, where set A and set B can be different, or set B can be a subset of set A.

[0091] A UE can be RRC configured (e.g., based on RRC configuration) with a list of CSI reporting configuration states and associated resources that can be used for aperiodic CSI reporting (e.g., in parameter CSI-AperiodicTriggerStateList, which can include CSI-AperiodicTriggerState #0, CSI-AperiodicTriggerState #1, …, CSI-AperiodicTriggerState #N). Each of the CSI reporting configuration states (e.g., each of CSI-AperiodicTriggerState #0, CSI-AperiodicTriggerState #1, …, CSI-AperiodicTriggerState #N) can include one or more CSI reporting configuration information (e.g., which can be parameter CSI-AssociatedReportConfigInfo), which can each include a CSI report setting identifier (ID), one or more CMR sets in CMRs configured to be associated with the CSI report setting, a CSI-RS or a set of CSI-IMs in CSI-Interference Measurements (CSI-IMs) or CSI-RSs associated with the CSI report setting for interference measurement. As used herein, the term “IMR” can refer to any resource for measuring interference. As used herein, the term “CMR” can refer to any resource for measuring a channel. An AP CSI report can be carried in PUSCH, while a periodic (P) or semi-persistent (SP) CSI report can be carried in PUSCH or PUCCH. RRC configuration can also configure time domain (TD) resource allocation for PUSCH carrying AP CSI report, and CMRs or IMRs can be configured by CSI report settings and RRC configuration associated with CMR / IMR sets. A MAC-CE can activate one or more RRC configured CSI reporting configuration states, and a DCI (e.g., such as UL grant DCI or DL grant DCI) can trigger (e.g., by using CSI request field in DCI to map to MAC-CE activated CSI reporting configuration states to be triggered) one or more of the MAC-CE activated CSI reporting configuration states, such that a UE can send a CSI report based on the triggered CSI reporting configuration state. The CSI request field in DCI can map to MAC-CE activated AperiodicTriggerState to be triggered, where parameter AperiodicTriggerState, where parameter Indicates the amount of bits in the UL grant DCI associated with the CSI request field. An example CSI-AperiodicTriggerStateList parameter is provided below: CSI-AperiodicTriggerStateList Information element -- ASN1START -- TAG-CSI-APERIODICTRIGGERSTATELIST-START CSI-AperiodicTriggerStateList ::= SEQUENCE (SIZE (1..maxNrOfCSI-AperiodicTriggers)) OF CSI-AperiodicTriggerState CSI-AperiodicTriggerState ::= SEQUENCE { associatedReportConfigInfoList SEQUENCE (SIZE(1..maxNrofReportConfigPerAperiodicTrigger)) OF CSI-AssociatedReportConfigInfo, ..., [[ ap-CSI-MultiplexingMode-r17 ENUMERATED {enabled} OPTIONAL -- NeedR ]] } CSI-AssociatedReportConfigInfo ::= SEQUENCE { reportConfigId CSI-ReportConfigId, resourcesForChannel CHOICE { nzp-CSI-RS SEQUENCE { resourceSet INTEGER (1..maxNrofNZP-CSI-RS-ResourceSetsPerConfig), qcl-info SEQUENCE (SIZE(1..maxNrofAP-CSI-RS-ResourcesPerSet)) OF TCI-StateId OPTIONAL -- Cond Aperiodic }, csi-SSB-ResourceSet INTEGER (1..maxNrofCSI-SSB-ResourceSetsPerConfig) }, csi-IM-ResourcesForInterference INTEGER(1..maxNrofCSI-IM-ResourceSetsPerConfig) OPTIONAL, -- Cond CSI- IM-ForInterference nzp-CSI-RS-ResourcesForInterference INTEGER (1..maxNrofNZP-CSI-RS-ResourceSetsPerConfig) OPTIONAL, -- Cond NZP-CSI-RS-ForInterference ..., [[ resourcesForChannel2-r17 CHOICE { nzp-CSI-RS2-r17 SEQUENCE { resourceSet2-r17 INTEGER (1..maxNrofNZP-CSI-RS-ResourceSetsPerConfig), qcl-info2-r17 SEQUENCE (SIZE(1..maxNrofAP-CSI-RS-ResourcesPerSet)) OF TCI-StateId OPTIONAL -- Cond Aperiodic }, csi-SSB-ResourceSet2-r17 INTEGER (1..maxNrofCSI-SSB-ResourceSetsPerConfigExt) } OPTIONAL, -- Cond NoUnifiedTCI csi-SSB-ResourceSetExt INTEGER (1..maxNrofCSI-SSB-ResourceSetsPerConfigExt) OPTIONAL -- Need R ]] } -- TAG-CSI-APERIODICTRIGGERSTATELIST-STOP -- ASN1STOP

[0092] IE ap-CSI-MultiplexingMode can indicate ap-CSI-MultiplexingMode. IE csi-IM-ResourcesForInterference can indicate IMR and can indicate CSI-IM-ResourceSet for interference measurement. IEs csi-SSB-ResourceSet, csi-SSB-ResourceSet2 can indicate CMR and can indicate CSI-SSB-ResourceSet for channel measurement. When nrofReportedGroups-r17 is configured in IE CSI-ReportConfig, IE resourcesForChannel2 can indicate CMR and can indicate reference signals for channel measurement corresponding to the second resource set for L1-RSRP measurement as configured in IE CSI-ResourceConfig. UE nzp-CSI-RS-ResourcesForInterference can indicate non-zero power (NZP)-CSI-RS-ResourceSet for interference measurement.

[0093] There can be timeline adjustments associated with CSI reporting. As used herein, the term "timeline adjustment" refers to a mechanism related to timeline where the UE can transmit a CSI report based on a trigger or ignore a trigger based on a timeline. As an example timeline adjustment, for the 1st CSI report associated with AP-CMR / IMR triggered by DCI, the UE can be provided with a timeline adjustment of K1 symbols. AP-CSI report, if the 1st uplink symbol for carrying the AP-CSI report including the impact of TA does not start earlier than symbol AP-CSI report including the timing advance (TA) does not start earlier than symbol AP-CSI report does not start earlier than symbol AP-CSI report. The UE can provide a valid 1st CSI report. The symbol may be a reference symbol, such as the start of its cyclic prefix (CP) after the end of the last symbol of the PDCCH carrying the DCI may be the next UL symbol after the end of the latest last symbol of the AP-CMR / IMR may be another reference symbol, such as the start of its CP after the end of the latest last symbol of the AP-CMR / IMR may be the next UL symbol after the end of the latest last symbol of the AP-CMR / IMR. Parameter may be a time unit. Parameter may represent a decoding time based on processing time, and can be associated with a SCS. Parameter and may be based on a SCS, one or more quantities to be included in the CSI report, such as RSRP, SINR, channel quality indicator (CQI), precoding matrix indicator (PMI), etc. (e.g., represented by IE reportQuantity), a number of CSI-RS ports for PMI feedback, whether the report is a wideband PMI or a subband-specific PMI, and a capability of the UE for RSRP / SINR feedback. As used herein, the term “one or more quantities to be included in the CSI report” can refer to information carried by IE reportQuantity, which can include quantities to be included in the CSI report, such as quantities of RSRP, SINR, CQI, PMI, etc.

[0094] Figure 5 is a diagram 500 illustrating an example timeline adjustment associated with an AP CSI report with an AP-CMR or an AP-IMR. As Figure 5 illustrated, a PDCCH 502 can carry a DCI triggering one or more AP-CSI reports associated with a CMR or an IMR. The associated CMR or IMR can be an AP-CMR 504 or an AP-IMR 506. The triggered one or more AP-CSI reports can be transmitted in a PUSCH 508. The time 512 between the PDCCH 502 carrying the DCI triggering the one or more AP-CSI reports and the PUSCH 508 carrying the one or more AP-CSI reports can be greater than , which can be based on parameter . The time 514 between the associated CMR or IMR (such as the later one of the AP-CMR 504 or the AP-IMR 506) and the PUSCH 508 carrying the one or more AP-CSI reports can be greater than , which can be based on parameter .

[0095] If the first uplink symbol for carrying the CSI report triggered by the DCI is later than the feedback via PUSCH Start, then the UE can ignore the DCI if there is no HARQ-ACK or transport block (TB) multiplexed on the PUSCH. If the DCI is used to carry the first CSI report that is triggered by the DCI. Start, then the UE can ignore the DCI if the triggered report is #1 and there is no HARQ-ACK / TB multiplexed on the PUSCH, otherwise, the UE can not update the first CSI report.

[0096] Aspects provided herein can enable reduced CSI-RS overhead, such as AP-CSI-RS overhead, UE power consumption, and CSI latency, via beam prediction. In some wireless communication systems, AP CSI reporting is associated with CMR / IMR. However, there can be a large number of beams, and different beams can be associated with different AP-CMRs (such as AP-NZP-CSI-RS), and the overhead can be large. Additionally, for a UE that is to measure the AP-CMR, the UE’s RF can be active, resulting in power consumption. Additionally, CSI latency can be significant due to having two reference symbols and reference symbols To reduce CSI-RS overhead, UE power consumption, and CSI latency, aspects provided herein can provide triggering of CSI reports (such as AP, P, or SP CSI reports) without association to measured CMR or measured IMR. To facilitate such aspects, the AP CSI reporting triggering framework can be enhanced. For example, RRC configuration associated with a CSI report (such as CSI-AssociatedReportConfigInfo) can be enhanced such that a UE knows whether an AP CSI report is triggered with a CMR / IMR that is actually transmitted (measured) or without a CMR / IMR that is configured to be transmitted (or actually transmitted). A MAC-CE that activates a CSI report configuration state (e.g., CSI-AperiodicTriggerState) can indicate whether a CSI report can be accompanied with or without a CMR or IMR that is configured to be transmitted (which can additionally be referred to as “configured to be actually transmitted” or “actually transmitted”). In some aspects, a DCI that triggers a CSI report can indicate whether the triggered CSI report can be accompanied with a CMR or IMR that is configured to be transmitted. Aspects provided herein can also provide parameters and of reference symbols and For example, the network node can request the UE to predict the L1-RSRP or other metrics as if (e.g., based on the same time occasion as configured for transmission) an AP-CMR / IMR is transmitted when there is no CMR or IMR configured to be transmitted, while the timeline can be different (e.g., relaxed) due to the UE not measuring the CMR or IMR for the AP-CSI report. Since the P / SP-CMR can be based on historical measurements, the timeline adjustment can be different for P / SP CSI reports.

[0097] Figure 6 is a diagram 600 illustrating example communications between a network node 604 and a UE 602. As Figure 6 illustrated, the network node 604 can transmit an RRC configuration 606 to configure a list of CSI report configuration states and associated resources that can be used for CSI reporting. After transmitting the RRC configuration 606, the network node 604 can transmit a MAC-CE 608 to activate one or more of the RRC configured CSI report configuration states. After transmitting the MAC-CE 608, the network node 604 can transmit a DCI 610 (e.g., such as an UL grant DCI or a DL grant DCI) to trigger one or more of the MAC-CE activated CSI report configuration states (e.g., by using the CSI request field in the DCI to map to the MAC-CE activated CSI report configuration state to be triggered) such that the UE 602 can transmit a CSI report 618 based on the triggered CSI report configuration state. In some aspects, the CSI report 618 can be an AP CSI report. In some aspects, the CSI report 618 is not associated with a measured CMR or IMR. For example, the UE 602 can not be requested or configured to determine one or more report quantities in the CSI report 618 based on measuring a CMR or IMR. In some aspects, a CMR or IMR 612 can be transmitted and associated with the CSI report 618 despite the UE 602 not measuring. In some aspects, a CMR or IMR associated with the CSI report 618 can not be transmitted.

[0098] Referring now to Figure 7A , Figure 7A is a diagram 700 illustrating example AP CSI reports that are not associated with a measured AP-CMR or a measured AP-IMR, where a measured AP-CMR or a measured AP-IMR can or can not be transmitted. As Figure 7AThe PDCCH 702, as illustrated, can carry DCI (e.g., corresponding to 610) that triggers one or more AP-CSI reports (e.g., corresponding to 618) associated with a CMR or IMR (e.g., corresponding to 612). The associated CMR or IMR can be an AP-CMR 704 or an AP-IMR 706. The triggered one or more AP-CSI reports can be transmitted in a PUSCH 708. The AP-CMR 704 or the AP-IMR 706 can be configured to be transmitted or configured not to be transmitted.

[0099] In some aspects, the UE can determine (e.g., identify) one or more quantities (e.g., reportQuantity) to be included in the CSI report 618 at 614. In some aspects, the UE can also generate the CSI report at 614. In some aspects, based on a timeline adjustment associated with a CSI report that is not associated with a measured CMR or IMR (which can be different from a timeline adjustment associated with a CSI report that is associated with a measured CMR or IMR), the UE 602 can determine whether to update and transmit the CSI report 618 or to ignore the trigger and refrain from updating the CSI report at 616.

[0100] In some aspects, where the CMR or IMR 612 is not measured by the UE 602 but can still be transmitted and associated with the CSI report 618, the UE 602 can determine (e.g., identify) one or more quantities (e.g., reportQuantity) to be included in the CSI report 618 without regard to the CMR or IMR 612. In some aspects, if the CMR or IMR 612 is configured to be transmitted, the UE 602 can rate match around the CMR or IMR 612. In some aspects, if the CMR or IMR 612 is configured not to be transmitted, the UE 602 can not rate match around the CMR or IMR 612.

[0101] In some aspects, when the CMR or IMR 612 is configured not to be transmitted, the RRC configuration 606, such as an IE CSI-AssociatedReportConfiglnfo, can configure the CMR or IMR 612. For example, the IE CSI-AssociatedReportConfiglnfo configured by the RRC configuration 606 and associated with the CSI report 618 can configure the CMR or IMR 612 to be transmitted or not to be transmitted. CSI-The AssociatedReportConfiglnfo can still include a selection of RRC configuration of a CMR / IMR set including the CMR or IMR 612. In some aspects, the UE can determine (e.g., identify) one or more quantities (e.g., reportQuantity) to include in the CSI report 618 based on the selection of RRC configuration of the CMR / IMR set including the CMR or IMR 612. For example, the UE 602 can report L1-RSRP / L1-SINR associated with the AP-CMR / IMR set selected by the CSI-AssociatedReportConfiglnfo without measuring the AP-CMR / IMR set. In some aspects, the UE 602 can not determine (e.g., identify) one or more quantities (e.g., reportQuantity) to include in the CSI report 618 based on the selection of RRC configuration of the CMR / IMR set including the CMR or IMR 612. In some aspects, the UE 602 can determine whether to determine (e.g., identify) one or more quantities (e.g., reportQuantity) to include in the CSI report 618 based on the selection of RRC configuration of the CMR / IMR set including the CMR or IMR 612 based on the RRC configuration 606, the DCI 610, or the MAC-CE 608.

[0102] In some aspects, the RRC configuration 606 (such as the IE CSI-AssociatedReportConfiglnfo in the RRC configuration 606) can further configure whether one or more quantities (e.g., reportQuantity) to be included in the CSI report 618 can be based on UE prediction instead of measurement. In some aspects, the RRC configuration 606 (such as the IE CSI-AssociatedReportConfiglnfo in the RRC configuration 606) can further indicate whether the CMR or IMR 612 is configured to be transmitted or not to be transmitted. In some aspects, the UE 602 can be configured with information about whether the CMR or IMR 612 is configured to be transmitted or not to be transmitted without signaling.

[0103] In some aspects, the MAC-CE 608 that can activate the CSI-AperiodicTriggerState can further configure whether one or more quantities (e.g., reportQuantity) to be included in the CSI report 618 can be based on UE prediction instead of measurement. In some aspects, the MAC-CE 608 can further indicate whether the CMR or IMR 612 is configured to be transmitted or not to be transmitted.

[0104] In some aspects, the DCI 610 that triggers the CSI report 618 (which can trigger a CSI-AperiodicTriggerState) can further configure whether one or more quantities (e.g., reportQuantity) to be included in the CSI report 618 can be based on UE prediction rather than measurement. In some aspects, the DCI 610 can further indicate whether the CMR or IMR 612 is configured to be transmitted or configured not to be transmitted. In some aspects, the UE 602 can be configured with information regarding whether the CMR or IMR 612 is configured to be transmitted or configured not to be transmitted without signaling.

[0105] In some aspects in which the RRC configuration 606 (such as the IE CSI-AssociatedReportConfiglnfo) configures the CMR or IMR 612, if the CMR or IMR is configured not to be transmitted, the UE 602 can (e.g., at 614) identify one or more quantities (such as by identifying one or more quantities to be included in the CSI report 618 (e.g., reportQuantity) based on a time occasion associated with the CMR or IMR 612) to be included in the CSI report 618 (e.g., reportQuantity) regarding the CMR or IMR 612. In some aspects, the RRC configuration 606 (such as the IE CSI-AssociatedReportConfiglnfo) can configure a different time occasion (which can be referred to as a “prediction target”) for identifying one or more quantities (e.g., reportQuantity) to be included in the CSI report 618. As used herein, the term “prediction target” can refer to a time occasion associated with a CSI report that is not associated with a configured CMR / IMR.

[0106] In some aspects, if the CMR or IMR is configured to be transmitted, the UE 602 can (e.g., at 614) identify one or more quantities to be included in the CSI report 618 (e.g., reportQuantity) for the CMR or IMR 612, such as by identifying the one or more quantities to be included in the CSI report 618 (e.g., reportQuantity) based on a time occasion associated with the CMR or IMR 612. In some aspects, the RRC configuration 606 (such as the IE CSI-AssociatedReportConfiglnfo) can configure different time occasions (which can be referred to as “prediction targets”) for identifying the one or more quantities to be included in the CSI report 618 (e.g., reportQuantity).

[0107] Referring now to Figure 7B , Figure 7B is a diagram 750 illustrating example AP CSI reports that are not associated with a measured AP-CMR or a measured AP-IMR, where the AP CSI reports can be based on a time occasion of a non-transmitted AP-CMR or a non-transmitted AP-IMR, as if the AP-CMR or AP-IMR were transmitted, or based on a different prediction target. As Figure 7B illustrated, the PDCCH 752 can carry DCI (e.g., corresponding to 610) that triggers one or more AP-CSI reports (e.g., corresponding to 618) associated with a CMR or IMR (e.g., corresponding to 612). The associated CMR or IMR can be an AP-CMR 754 or an AP-IMR 756. The triggered one or more AP-CSI reports can be transmitted in the PUSCH 758. The AP-CMR 754 or AP-IMR 756 can be configured to be transmitted or configured not to be transmitted. The MAC-CE 751, DCI, or RRC configuration can configure the CSI report to be based on a time occasion associated with the AP-CMR 754 or AP-IMR 756, or a different time occasion associated with a prediction target 770.

[0108] In some aspects, the CSI report 618 can be an AP, P, or SP CSI report. In some aspects, if the CSI report 618 is a P / SP CSI report, the CMR or IMR 612 can be transmitted and the UE 602 can identify one or more quantities (e.g., reportQuantity) to be included in the CSI report 618 based on prediction rather than measurement. In some aspects in which the CSI report 618 is a SP CSI report, the MAC-CE 608 can indicate whether the UE 602 can identify one or more quantities (e.g., reportQuantity) to be included in the CSI report 618 based on measurement of the CMR or IMR 612 associated with the CSI setting. The MAC-CE 608 can also indicate whether the CMR or IMR 612 associated with the CSI setting is configured to be transmitted.

[0109] In some aspects, the RRC configuration 606, such as the IE CSI-AssociatedReportConfiglnfo, can not configure a CMR or IMR associated with a CSI report. For example, the IE CSI-AssociatedReportConfiglnfo can not include a selection of a set of RRC-configured CMRs / IMRs. In some such aspects, one or more quantities (e.g., reportQuantity) to be included in the CSI report 618 can be configured by the RRC configuration 606 based on different prediction targets (e.g., associated with different sets of resources, such as sets of resources associated with different beams). The MAC-CE 608 can activate and the DCI 610 can trigger different resources associated with the prediction targets. In some aspects, the RRC configuration 606, the MAC-CE 608, or the DCI 610 can indicate a time occasion associated with the prediction target. For example, the CSI report setting or the set of prediction resources can indicate that the UE 602 assumes that such a set of prediction resources should be present there for a TD occasion to identify the reportQuantity. Alternatively, the CSI-AssociatedReportConfiglnfo can indicate that the UE assumes that such a set of prediction resources should be present there for a time occasion to identify the reportQuantity. In some aspects, the CSI-AssociatedReportConfiglnfo can indicate a plurality of occasions that can be selected by the MAC-CE 608 or the DCI 610.

[0110] In some aspects, timeline adjustments associated with a CSI report that is not associated with a measured CMR or a measured IMR can be based on a time duration defined separately for a CSI report that is not associated with a measured CMR or a measured IMR or Values ​​(e.g., those associated with CSI reports of measured CMR or measured IMR) or (Values ​​are separated). In some respects, CSI reports are defined separately for CMR measurements that are not associated with the measured CMR or the measured IMR. or The value can be based on one or more of the following: (1) the target time timing associated with the forecast (e.g., a larger value if the target TD timing is about a long time in the future). (1) Can be defined as allowing the UE more time to identify the prediction results), (2) the network-indicated beam characteristics of the prediction target (e.g., CMR or IMR 612 or different prediction targets), which may include explicitly indicated beamwidth, beamforming gain, pointing direction or their relative values ​​with reference to other SSB / CSI-RS or implicitly indicated beam adjacency information, (3) the total number of prediction target resources (e.g., the total number of resources of CMR or IMR 612 or different prediction targets), (4) whether CMR or IMR 612 is configured to be transmitted, (5) reportQuantity details associated with the prediction target resources, such as L1-RSRP, L1-SINR, the first K resources according to L1-RSRP / L1-SINR (and the value of K), (6) about parameters The ability to report UE data (regarding processing time) or other parameters.

[0111] Figure 8 This is a diagram 800 illustrating example processing times associated with AP CSI reports that have AP-CMR or AP-IMR. (See diagram 800.) Figure 8 As illustrated, PDCCH 802 may carry a DCI that triggers one or more AP-CSI reports associated with a CMR or IMR. The associated CMR or IMR may be AP-CMR 804 or AP-IMR 806. One or more triggered AP-CSI reports may be sent in PUSCH 808. During time 820 between PDCCH 802 and AP-CMR 804, there may be UL symbols that may be considered due to Time Division Duplex (TDD). During time 830 between AP-IMR 806 and PUSCH 808, there may be DL slots that may be considered due to TDD. The time 812 between PDCCH 802 carrying a DCI that triggers one or more AP-CSI reports and PUSCH 808 carrying one or more AP-CSI reports may be greater than... It can be based on parameters The time 814 between the associated CMR or IMR (such as the later of the AP-CMR 804 or the AP-IMR 806) and the PUSCH 808 carrying the one or more AP-CSI reports can be greater than which can be based on the parameters .

[0112] Figure 9 is a diagram 900 illustrating an example processing time associated with an AP-CSI report that is not associated with a measured AP-CMR or a measured AP-IMR. As Figure 9 illustrated, the PDCCH 902 can carry a DCI that triggers one or more AP-CSI reports that can be transmitted in the PUSCH 908. Since no measurement is performed, the time 912 between the PDCCH 902 and the PUSCH 908 can be shorter than for an AP-CSI report associated with a measured AP-CMR or a measured AP-IMR, which can result in lower complexity and no adjustment for .

[0113] In some aspects, the DCI 610 can be a UL grant DCI scheduling a PUSCH for transmitting the CSI report 618 or a DL grant DCI scheduling a separate PDSCH 620. By enabling the CSI report 618 to be triggered with a DL grant DCI, latency can be reduced by not waiting for a UL grant DCI to trigger the CSI report. Referring now to Figure 10A , Figure 10A is a diagram 1000 illustrating an example DL grant DCI for triggering a CSI report.

[0114] As Figure 10A illustrated, if a UL grant DCI 1002 schedules a PUSCH 1004 and the network is not aware of the scheduled CSI report, the network can use a subsequent DL grant DCI 1006 to trigger the CSI report in the PUSCH 1004 without waiting for another UL grant DCI, thereby reducing latency. In some of such aspects, the time adjustment can be different for a DL grant DCI triggering a CSI report or a UL grant DCI triggering a CSI report. For example, for a DL grant DCI triggering a CSI report, the timeline adjustment for configured grant (CG) PUSCH or dynamic PUSCH can be used.

[0115] Figure 10Bis a diagram 1050 illustrating example AP CSI reporting associated with a measured AP-CMR or a measured AP-IMR, where the AP CSI reporting can be based on a different prediction target than the measured AP-CMR or the measured AP-CMR. Referring now to Figure 10B , Figure 10B is a diagram 1050 illustrating example AP CSI reporting associated with a measured AP-CMR or a measured AP-IMR, where the AP CSI reporting can be based on a different prediction target. As illustrated in Figure 10B , a PDCCH 1052 can carry a DCI that triggers one or more AP-CSI reports associated with a CMR or an IMR after activation based on a MAC-CE 1051. The associated CMR or IMR can be an AP-CMR 1054 or an AP-IMR 1056. The triggered one or more AP-CSI reports can be transmitted in a PUSCH 1058. The AP-CMR 1054 or the AP-IMR 1056 can be configured to be transmitted and measured. A MAC-CE, a DCI, or an RRC configuration can configure the CSI report to be based on a different time occasion associated with a prediction target 1070 than the measured CMR / IMR. In some aspects, the time adjustment for such aspects can be based on a different value of a parameter 、 or defined separately for the CSI report associated with the measured CMR / IMR, but not based on the CMR / IMR. As an example, the prediction target can be based on a set of beams that can be different than a set of beams associated with the measured CMR / IMR.

[0116] Figure 11 is a flowchart 1100 of a method of wireless communication. The method can be performed by a UE (e.g., the UE 104; the apparatus 1604).

[0117] At 1102, the UE can receive, from a network node, a DCI that triggers an AP CSI report that is not associated with a measured CMR or a measured IMR. For example, the UE 602 can receive, from the network node 604, a DCI (e.g., 610) that triggers an AP CSI report (e.g., 618) that is not associated with a measured CMR or a measured IMR (e.g., 612). In some aspects, 1102 can be performed by the CSI component 198.

[0118] At 1104, the UE can transmit the AP CSI report based on a timeline adjustment associated with the AP CSI report. For example, the UE 602 can transmit the AP CSI report (e.g., 618) based on a timeline adjustment associated with the AP CSI report. In some aspects, 1104 can be performed by the CSI component 198.

[0119] Figure 12 FIG. 12 is a flowchart 1200 of a method of wireless communication. The method can be performed by a UE (e.g., the UE 104; the apparatus 1604).

[0120] At 1202, the UE can receive, from a network node, a DCI triggering an AP CSI report that is not associated with a measured CMR or a measured IMR. For example, the UE 602 can receive, from the network node 604, a DCI (e.g., 610) triggering an AP CSI report (e.g., 618) that is not associated with a measured CMR or a measured IMR (e.g., 612). In some aspects, 1202 can be performed by the CSI component 198. In some aspects, the DCI is a downlink grant DCI, and wherein the timeline adjustment is associated with the downlink grant DCI. In some aspects, the DCI is an uplink grant DCI, and wherein the timeline adjustment is associated with the uplink grant DCI. In some aspects, the AP CSI report is not associated with the measured CMR or the measured IMR based on the UE not being requested or configured to determine one or more quantities to be included in the AP CSI report based on measurements of the measured CMR or the measured IMR.

[0121] At 1204, the UE can transmit the AP CSI report based on the timeline adjustment associated with the AP CSI report. For example, the UE 602 can transmit the AP CSI report (e.g., 618) based on the timeline adjustment associated with the AP CSI report. In some aspects, 1204 can be performed by the CSI component 198.

[0122] In some aspects, the AP CSI report is associated with an RRC configuration (e.g., 606) that configures a non-measured CMR or a non-measured IMR (e.g., 612). In some aspects, the AP CSI report includes one or more reported metrics associated with the non-measured CMR or the non-measured IMR. In some aspects, the RRC configuration indicates whether one or more quantities to be included in the AP CSI report are based on prediction or measurement. In some aspects, the RRC configuration indicates whether the non-measured CMR or the non-measured IMR is configured for transmission. In some aspects, the non-measured CMR or the non-measured IMR is aperiodic. In some aspects, the non-measured CMR or the non-measured IMR is periodic or semi-persistent, and wherein the non-measured CMR or the non-measured IMR is configured to be transmitted.

[0123] In some aspects, at 1201, the UE can receive, from the network node, a medium access control (MAC) control element (MAC-CE) activating an aperiodic trigger associated with the AP CSI report prior to receiving the DCI triggering the AP CSI report, where the MAC-CE indicates whether one or more quantities to be included in the AP CSI report are based on prediction or measurement. For example, the UE 602 can receive, from the network node, a MAC-CE (e.g., 608) activating an aperiodic trigger associated with the AP CSI report prior to receiving the DCI triggering the AP CSI report, where the MAC-CE indicates whether one or more quantities to be included in the AP CSI report are based on prediction or measurement. In some aspects, 1201 can be performed by the CSI component 198. In some aspects, the MAC-CE indicates whether an unmeasured CMR or an unmeasured IMR is configured for transmission.

[0124] In some aspects, the MAC-CE indicates whether one or more quantities to be included in the AP CSI report are based on prediction or measurement. In some aspects, the MAC-CE indicates whether an unmeasured CMR or an unmeasured IMR is configured for transmission.

[0125] At 1210, the UE can identify one or more quantities to be included in the AP CSI report. For example, the UE 602 can identify (e.g., at 614) one or more quantities to be included in the AP CSI report. In some aspects, 1210 can be performed by the CSI component 198. In some aspects, an unmeasured CMR or an unmeasured IMR is configured not to be transmitted, and the UE can identify the one or more quantities to be included in the AP CSI report based on a time occasion associated with the unmeasured CMR or the unmeasured IMR, where the time occasion is configured for transmission of the unmeasured CMR or the unmeasured IMR. In some aspects, an unmeasured CMR or an unmeasured IMR is configured not to be transmitted, and the UE can identify the one or more quantities to be included in the AP CSI report based on a time occasion associated with the unmeasured CMR or the unmeasured IMR, where RRC configuration indicates the time occasion. In some aspects, an unmeasured CMR or an unmeasured IMR is configured to be transmitted, and the UE can identify the one or more quantities to be included in the AP CSI report based on a time occasion associated with the unmeasured CMR or the unmeasured IMR, where the time occasion is configured for transmission of the unmeasured CMR or the unmeasured IMR. In some aspects, an unmeasured CMR or an unmeasured IMR is configured to be transmitted, and the UE can identify the one or more quantities to be included in the AP CSI report based on a time occasion associated with the unmeasured CMR or the unmeasured IMR, where RRC configuration indicates the time occasion.

[0126] In some aspects, the UE can receive, from the network node, a MAC-CE activating a semi-persistent (SP) CSI report, where the MAC-CE indicates whether one or more quantities to be included in the SP CSI report are based on RRC configuration. In some aspects, the MAC-CE indicates whether an unmeasured CMR or an unmeasured IMR is configured for transmission.

[0127] In some aspects, the AP CSI report is associated with a RRC configuration (e.g., 606) that does not configure an AP CMR or an AP IMR, where one or more quantities to be included in the AP CSI report are based on one or more predictions that are based on one or more predicted resources. In some aspects, the RRC configuration or another configuration indicates a time occasion associated with the one or more predicted resources.

[0128] In some aspects, the timeline adjustment is based on a reference symbol value (e.g., Z ref ). In some aspects, the reference symbol value is based on at least one of: a time occasion associated with a prediction associated with the AP CSI report, at least one beam property associated with a target associated with the prediction, a total amount of predicted resources associated with the prediction, whether the prediction is associated with a previously measured CMR or a previously measured IMR, or a capability associated with the UE.

[0129] At 1212, the UE can update the AP CSI report or refrain from updating (e.g., at 616) the AP CSI report based on the timeline adjustment associated with the AP CSI report, where transmission of the AP CSI report is based on the updating or refraining. For example, the UE 602 can update the AP CSI report or refrain from updating the AP CSI report based on the timeline adjustment associated with the AP CSI report, where transmission of the AP CSI report is based on the updating or refraining. In some aspects, 1212 can be performed by the CSI component 198.

[0130] In some aspects, the AP CSI report is associated with a transmitted CMR or a transmitted IMR. In some of such aspects, at 1214, the UE can rate match around the transmitted CMR or the transmitted IMR. For example, the UE 602 can rate match around the transmitted CMR or the transmitted IMR (e.g., 612). In some aspects, 1214 can be performed by the CSI component 198.

[0132] At 1302, the UE can receive, from a network node, DCI triggering an AP CSI report associated with a measured CMR or a measured IMR, where one or more quantities to be included in the AP CSI report are based on one or more prediction targets separate from the measured CMR or the measured IMR. For example, the UE 602 can receive, from the network node 604, DCI (e.g., in 1052) triggering an AP CSI report (e.g., in 1058) associated with a measured CMR (e.g., 1054) or a measured IMR (e.g., 1056), where one or more quantities to be included in the AP CSI report are based on one or more prediction targets (e.g., 1070) separate from the measured CMR or the measured IMR. In some aspects, 1302 can be performed by the CSI component 198.

[0133] At 1304, the UE can transmit the AP CSI report based on a timeline adjustment associated with the AP CSI report.

[0135] At 1402, the network entity can transmit, for a UE, DCI triggering an AP CSI report not associated with a measured CMR or a measured IMR. For example, the network node 604 can transmit, for the UE 602, DCI (e.g., 610) triggering an AP CSI report (e.g., 618) not associated with a measured CMR or a measured IMR (e.g., 612). In some aspects, 1402 can be performed by the CSI component 199.

[0136] At 1404, the network entity can obtain the AP CSI report. For example, the network node 604 can obtain the AP CSI report (e.g., 618). In some aspects, 1404 can be performed by the CSI component 199.

[0144] It should be understood that the particular order or hierarchy of steps in the processes / flow diagrams disclosed are merely examples. It should be appreciated that the specific order or hierarchy of steps in the processes / flow diagrams can be re-arranged based on design.

[0145] The preceding description is provided to enable any person skilled in the art to practice the various aspects described herein. Various modifications to these aspects will be readily apparent to those skilled in the art, and the generic principles defined herein can be applied to other aspects. Thus, the claims are not to be limited to the aspects described herein, but are to be given the full scope defined by the language of the claims. Unless otherwise defined, a reference to a singular element includes “one or more” thereof. Terms such as “if,” “when,” and “while” do not imply direct temporal relationships or reaction sequences. That is, a phrase referring to “when” does not mean “immediately upon” or “in response to” an action, but simply means that an action will occur if a condition is met, without requiring a specific or immediate temporal relationship to the action. The word “exemplary” is used herein to mean “serving as an example, instance, or illustration.” Any aspect described herein as “exemplary” is not necessarily to be construed as preferred or advantageous over other aspects. Unless specifically stated otherwise, the term “some” refers to one or more. Combinations such as “at least one of A, B, or C,” “one or more of A, B, or C,” “at least one of the group consisting of A, B, and C,” “one or more of the group consisting of A, B, and C,” and “A, B, and / or C” include the entire group of A, B, and / or C and can include combinations of one or more A, one or more B, or one or more C. Specifically, the combinations “at least one of A, B, or C,” “one or more of A, B, or C,” “at least one of the group consisting of A, B, and C,” “one or more of the group consisting of A, B, and C,” and “A, B, and / or C” can include A alone, B alone, C alone, A and B, A and C, B and C, or A and B and C, where any such combination can contain one or more members of A, B, or C. A set should be interpreted as a collection of elements that can be one or more. Accordingly, a set of X includes one or more X. When a set of one or more processors is configured to perform a set of functions, the set of one or more processors is configured to perform the set of functions individually or in any combination. Thus, each processor in the set of one or more processors can be configured to perform a particular subset of the set of functions, where the subset is a proper subset of the complete set, an appropriate subset of the set, or an empty subset of the set. If a first device receives data from a second device or sends data to the second device, the data can be received or sent directly from or to the first device and the second device, or indirectly through a set of devices between the first device and the second device. A device configured to “output” data, such as a signal or message, may, for example, send the data with a transceiver, or can transfer the data to a device that sends the data.A device configured to "obtain" data (such as transmit, signal, or message) can receive the data, e.g., with a transceiver, or can obtain the data from a device that receives the data. Information stored in memory includes instructions and / or data. All structural and functional equivalents to the elements of the various aspects described throughout this disclosure that are known or later come to be known to those of ordinary skill in the art are expressly incorporated herein by reference and are intended to be encompassed by the claims. Moreover, nothing disclosed herein is intended to be dedicated to the public regardless of whether such disclosure is explicitly recited in the claims. The words "module," "mechanism," "element," "device," and the like do not require that all of these components be implemented in a single physical entity. In addition, the described aspects can be implemented as a method, apparatus, or article of manufacture using standard devices, and can be implemented in software, hardware or firmware. The terms "first," "second," "third," etc. are used herein to denote different units (e.g., components). However, these units should not be construed to be limited to the three indicated units unless explicitly stated otherwise.

[0146] As used herein, the phrase "based on" shall not be construed as a reference to a closed set of information, conditions, factors, or the like that were supplied after the statement in which the phrase occurs, unless specifically stated otherwise. Rather, the phrase "based on" shall be construed as meaning "based, at least in part, on."
