Description

Technical Field

[0001] All aspects of this disclosure relate to wireless communication in general, and more particularly to techniques, apparatus and methods for measuring channel state information. Background Technology

[0002] Wireless communication systems are widely deployed to provide a variety of services, including voice, text, messaging, video, data, and / or other services. Services may include unicast, multicast, and / or broadcast services, etc. Typical wireless communication systems employ multiple access radio access technologies (RATs) capable of supporting communication with multiple users by sharing available system resources (e.g., time-domain resources, frequency-domain resources, spatial-domain resources, and / or device transmit power, etc.). Examples of such multiple access RATs 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] The aforementioned Multiple Access RATs have been adopted in various telecommunications standards to provide a common protocol enabling different wireless communication devices to communicate at the city, national, regional, or global level. An example telecommunications standard is New Radio (NR). NR (also known as 5G) is part of the continuous evolution of mobile broadband announced by the 3rd Generation Partnership Project (3GPP). NR (and other mobile broadband evolutions beyond NR) can be designed to better support the Internet of Things (IoT) and reduced-capacity device deployments, industrial connectivity, millimeter-wave (mmWave) expansion, licensed and unlicensed spectrum access, non-terrestrial network (NTN) deployments, sidelinks and other device-to-device direct communication technologies (e.g., cellular vehicle-to-everything (CV2X) communications), massive MIMO, decomposed network architectures and network topology expansion, multi-subscriber implementations, high-precision positioning and / or radio frequency (RF) sensing, and more. As the demand for mobile broadband access continues to grow, further improvements to NR can be implemented, and other radio access technologies (such as 6G) can be introduced to further advance mobile broadband evolution.

[0004] Communication channels can vary over time based on one or more conditions. For example, the channel can vary based on Doppler conditions, obstruction conditions, interference conditions, weather conditions, or user equipment (UE) mobility conditions, etc. Doppler conditions can be the Doppler effect that occurs when the frequency of a communication signal changes, for example, due to relative motion between the transmitter and receiver. The temporal variability of the channel indicates the rate at which the channel changes over time. In some cases, the temporal variability of the channel used for communication between the network node and the UE can be identified based on a Channel State Information Reference Signal (TRS) used for tracking. For example, the UE can receive a TRS from the network node, use the TRS to perform one or more measurements, and send a time-domain channel attribute report indicating the temporal variability of the channel based on the one or more TRS measurements to the network node.

[0040] Various aspects of this disclosure are described below with reference to the accompanying drawings. However, aspects of this disclosure may be embodied in many different forms and should not be construed as limited to any specific aspect illustrated or described with reference to the drawings or otherwise presented in this disclosure. Rather, these aspects are provided so that this disclosure will be comprehensive and complete, and will fully convey the scope of protection of this disclosure to those skilled in the art. Those skilled in the art will understand that the scope of this disclosure is intended to cover any aspect of this disclosure disclosed herein, whether implemented independently of or in combination with any other aspect of this disclosure. For example, various combinations or numbers of aspects set forth herein may be used to implement an apparatus or a practice. Furthermore, the scope of this disclosure is intended to cover apparatuses having structures and / or functionalities other than those available for practicing the various aspects of this disclosure set forth herein, or methods practiced using these other structures and / or functionalities. Any aspect of this disclosure disclosed herein may be embodied by one or more elements of the claims.

[0041] Various methods, operations, apparatuses, and techniques will now be presented with reference to them. These methods, operations, apparatuses, and techniques will be described in detail below and illustrated in the accompanying drawings by various boxes, modules, components, circuits, steps, processes, or algorithms (collectively, “elements”). These elements may be implemented using hardware, software, or a combination of hardware and software. Whether such elements are implemented as hardware or software depends on the specific application and the design constraints imposed on the system as a whole.

[0042] Communication channels can vary over time based on one or more conditions. For example, channels can vary based on Doppler conditions, masking conditions, interference conditions, weather conditions, or user equipment (UE) mobility conditions, etc. The temporal variability of a channel indicates the rate at which the channel changes over time. In some cases, the temporal variability of the channel used for communication between a network node and a UE can be identified based on a Channel State Information (CSI) Reference Signal (CSI-RS) used for Tracking Reference Signals (TRS). For example, a UE can receive a TRS from a network node, perform one or more measurements using the TRS, and send a Time Domain Channel Attribute (TDCP) report indicating the temporal variability of the channel based on the one or more TRS measurements to the network node. In some cases, a UE can store information associated with the number of CSI-RSs in a resource configuration for that UE. For example, a UE can store an aperiodic TRS symbol index, frequency domain tone offset, and scrambling identifier in its low-level driver memory and for each CSI-RS resource included in the resource configuration. For example, when the number of CSI-RS resources included in the resource configuration (e.g., 128 CSI-RS resources) is greater than the number of aperiodic TRS resources that will be measured by the UE, this may lead to a waste of UE memory resources. Additionally, when network nodes send aperiodic CSI-RS resources that will not be measured by the UE, this may lead to a waste of network resources.

[0043] In some cases, communication signals between the UE and network nodes may experience the Doppler effect. The Doppler effect can occur when the frequency of the communication signal changes, for example, due to relative motion between the transmitter and receiver. The Doppler effect can be classified as either Type I or Type II Doppler conditions. Type I Doppler conditions can occur based on rapid and / or random motion between the transmitter and receiver. In some cases, this may be a result of objects or obstacles interfering with the path of the communication signal and may lead to small-scale attenuation, including rapid fluctuations in the amplitude and / or phase of the communication signal. In contrast, Type II Doppler conditions can occur based on slower and / or more predictable motion between the transmitter and receiver. In some cases, this may be a result of the receiver moving within the transmitter's coverage area and may lead to large-scale attenuation, including slower fluctuations in the amplitude and / or phase of the communication signal. In some cases, the measurement window used to perform Doppler measurements may not be defined according to the UE's capabilities. This could result in a measurement window that is shorter than the time required to perform a Doppler measurement, potentially preventing the UE from performing at least a portion of the Doppler measurement. Alternatively, it could result in a measurement window that is longer than the time required to perform a Doppler measurement, leading to wasted network resources. In some cases, the UE can use a number of occupied CSI processing units to perform Doppler measurements. However, the number of occupied CSI processing units may not be defined based on UE capability information, potentially resulting in the UE not having sufficient resources to perform CSI-RS and / or Doppler measurements.

[0044] Various aspects are involved in wireless communication as a whole. Some aspects are more specifically related to CSI-RS measurements. In some aspects, the UE may transmit information indicating the maximum number of aperiodic tracking reference signals used for CSI reporting. In one example, transmitting information indicating the maximum number of aperiodic tracking reference signals may include transmitting information indicating the maximum number of aperiodic tracking reference signals configured at the UE for resource configuration. In another example, transmitting information indicating the maximum number of aperiodic tracking reference signals may include transmitting information indicating the maximum number of time-domain channel attribute reporting settings. In some examples, the UE may transmit capability information indicating the time slot offset between multiple tracking reference signal resource sets. The UE may receive one or more aperiodic tracking reference signals from the network node based on the indication of the maximum number of aperiodic tracking reference signals. In some other aspects, the UE may generate a parameter indicating the number of CSI-RS measurements supported by the UE according to the periodic channel state information reference signal configuration. The UE may calculate the measurement window based on this parameter and may send an indication of this parameter and / or an indication of the CSI timeline indicator to the network node. In some examples, the UE may identify the number of occupied CSI processing units used for CSI reporting and may send an indication of that number of occupied CSI processing units to the network node. The UE may receive one or more CSI-RS from the network node and / or may perform one or more CSI-RS measurements based on the parameter and / or the CSI timeline indicator.

[0045] Specific aspects of the subject matter described in this disclosure can be implemented to achieve one or more of the following potential advantages. In some examples, by sending an indication of the maximum number of aperiodic tracking reference signals used for CSI reporting, the described techniques can be used to reduce the amount of CSI-RS measurement information stored in the UE's memory (such as the UE's low-level drive memory). For example, by sending information indicating the maximum number of aperiodic tracking reference signals configured at the UE, the UE can directly indicate which CSI-RS resources will be measured by the UE, and thus avoid storing information associated with CSI-RS resources that will not be measured by the UE. Additionally or alternatively, by sending information indicating the maximum number of time-domain channel attribute report settings, the UE can avoid storing information associated with CSI-RS resources that will not be transmitted by network nodes according to the time-domain channel attribute report settings. In some examples, by sending an indication of the maximum number of aperiodic tracking reference signals used for CSI reporting, the described techniques can be used to reduce network bandwidth associated with communicating CSI-RS resources that will not be measured by the UE. In some examples, by sending information indicating the ability to time slot offsets between multiple tracking reference signal resource sets, the described techniques can be used to increase the likelihood of buffering a first tracking reference signal resource set before one or more other tracking reference signal resource sets are received by the UE, which can improve the accuracy of tracking reference signal resource set processing. In some examples, by calculating the CSI timeline indicator based on this parameter, the UE can align the measurement window with the CSI-RS measurement to be performed by the UE. For example, by sending an indication of this parameter and / or the CSI timeline indicator, the described techniques can be used to reduce the likelihood that the measurement window is shorter than the time associated with performing the CSI-RS measurement and / or reduce the likelihood that the measurement window is longer than the time associated with performing the CSI-RS measurement. The advantages of these examples, etc., will be described in more detail below.

[0046] Multiple access radio access technology (RAT) has been adopted in various telecommunications standards to provide a common protocol that enables different wireless communication devices to communicate at the city, enterprise, national, regional, or global levels. For example, 5G New Radio (NR) is part of the Continuous Mobile Broadband Evolution program released by the 3rd Generation Partnership Project (3GPP). 5G NR supports a variety of technologies and use cases, including enhanced mobile broadband (eMBB), ultra-reliable low-latency communication (URLLC), massive machine-type communication (mMTC), millimeter wave (mmWave) technology, beamforming, network slicing, edge computing, Internet of Things (IoT) connectivity and management, and network function virtualization (NFV).

[0047] With the increasing demand for broadband access and the evolution of technologies supported by wireless communication networks, further technological improvements can be adopted or implemented in 5G NR or future RATs (such as 6G) to further drive the evolution of wireless communication for a variety of existing and new use cases and applications. Such technological improvements can be associated with: new frequency band extensions, licensed and unlicensed spectrum access, overlapping spectrum use, small cell deployments, non-terrestrial network (NTN) deployments, decomposed network architectures and network topology extensions, device aggregation, advanced duplex communication, sidelinks and other device-to-device direct communication, IoT (including passive or ambient IoT) networks, reduced-capacity (RedCap) UE functionality, industrial connectivity, multi-subscriber implementations, high-precision positioning, radio frequency (RF) sensing and / or artificial intelligence or machine learning (AI / ML), etc. Such technological improvements can support use cases such as: wireless backhaul, wireless data centers, extended reality (XR) and metaverse applications, meta-services for supporting vehicle connectivity, holographic and mixed reality communications, autonomous and collaborative robots, vehicle platooning and cooperative manipulation, sensor networks, gesture detection, brain-computer interfaces, digital twin applications, asset management, and general coverage applications using off-ground and / or aerial platforms, etc. The methods, operations, apparatuses, and techniques described herein can facilitate one or more of the aforementioned technologies and / or support one or more of the aforementioned use cases.

[0048] Figure 1 This is a diagram illustrating an example of a wireless communication network 100 according to the present disclosure. The wireless communication network 100 may be a 5G (or NR) network or a 6G network, or may include elements of a 5G (or NR) network or a 6G network, etc. The wireless communication network 100 may include a plurality of network nodes 110, shown as network node (NN) 110a, network node 110b, network node 110c, and network node 110d. Network nodes 110 may support communication with a plurality of UEs 120 (shown as UE 120a, UE 120b, UE 120c, UE 120d, and UE 120e).

[0049] Network nodes 110 and UEs 120 of wireless communication network 100 can communicate using the electromagnetic spectrum, which can be subdivided into various categories, frequency bands, carriers, and / or channels according to frequency or wavelength. For example, devices of wireless communication network 100 can communicate using one or more operating frequency bands. In some aspects, multiple wireless networks 100 can be deployed in a given geographical area. Each wireless communication network 100 can support a specific RAT (which may also be referred to as an air interface) and can operate on one or more carrier frequencies in one or more frequency ranges. Examples of RATs include 4G RATs, 5G / NRRATs, and / or 6G RATs, etc. In some examples, when multiple RATs are deployed in a given geographical area, each RAT in that geographical area can operate on a different frequency to avoid interference with each other.

[0050] Various operating frequency bands have been defined as frequency ranges designated FR1 (410 MHz to 7.125 GHz), FR2 (24.25 GHz to 52.6 GHz), FR3 (7.125 GHz to 24.25 GHz), FR4a or FR4-1 (52.6 GHz to 71 GHz), FR4 (52.6 GHz to 114.25 GHz), and FR5 (114.25 GHz to 300 GHz). Although a portion of FR1 is greater than 6 GHz, in some documents and articles, FR1 is often (interchangeably) referred to as the “sub-6 GHz” band. Similarly, in some documents and articles, FR2 is often (interchangeably) referred to as the “millimeter wave” band, but this is different from the Very High Frequency (EHF) band (30 GHz to 300 GHz) identified as the “millimeter wave” band by the International Telecommunication Union (ITU). The frequencies between FR1 and FR2 are often referred to as the mid-band frequencies, including FR3. Frequency bands falling within FR3 can inherit FR1 or FR2 characteristics, thereby effectively extending the characteristics of FR1 or FR2 into mid-band frequencies. Therefore, "below 6 GHz" (if used herein) can broadly refer to frequencies less than 6 GHz, within FR1, and / or included in mid-band frequencies. Similarly, the term "millimeter wave" (if used herein) can broadly refer to frequencies included in mid-band frequencies, within FR2, FR4, FR4-a, FR4-1, or FR5, and / or within the EHF band. Higher frequency bands can extend 5G NR operation, 6G operation, and / or other RATs above 52.6 GHz. For example, each of FR4a, FR4-1, FR4, and FR5 falls within the EHF band. In some examples, the wireless communication network 100 can implement dynamic spectrum sharing (DSS), where multiple RATs (e.g., 4G / LTE and 5G / NR) are implemented within a single frequency band using dynamic bandwidth allocation (e.g., based on user demand). It is conceivable that the frequencies included in these operating frequency bands (e.g., FR1, FR2, FR3, FR4, FR4-a, FR4-1 and / or FR5) can be modified, and the techniques described herein are applicable to those modified frequency ranges.

[0051] Network node 110 may include one or more devices, components, or systems that enable communication between UE 120 and one or more devices, components, or systems of wireless communication network 100. Network node 110 may be, may include, or may also be referred to as an NR network node, 5G network node, 6G network node, node B, eNB, gNB, access point (AP), transmit / receive point (TRP), mobility element, core, network entity, network element, network equipment, and / or another type of device, component, or system included in a radio access network (RAN).

[0052] Network node 110 may be implemented as a single physical node (e.g., a single physical structure) or as two or more physical nodes (e.g., two or more different physical structures). For example, network node 110 may be a device or system implementing a portion of a radio protocol stack, a device or system implementing a complete radio protocol stack (such as a complete gNB protocol stack), or a collection of devices or systems collectively implementing a complete radio protocol stack. For example, as shown, network node 110 may be an aggregated network node (with an aggregated architecture), meaning that network node 110 can implement a complete radio protocol stack physically and logically integrated within a single node (e.g., a single physical structure) in the wireless communication network 100. For example, aggregated network node 110 may consist of a single standalone base station or a single TRP that uses a complete radio protocol stack to implement or facilitate communication between UE 120 and the core network of wireless communication network 100.

[0053] Alternatively, and also as shown in the figure, network node 110 can be a decomposed network node (sometimes referred to as a decomposed base station), meaning that network node 110 can realize a radio protocol stack that is physically distributed and / or logically distributed among two or more nodes in the same or different geographical locations. For example, a decomposed network node may have a decomposed architecture. In some deployments, decomposed network node 110 may be used in integrated access and backhaul (IAB) networks, in open radio access networks (O-RAN) (such as network configurations compliant with the O-RAN Alliance), or in virtualized radio access networks (vRAN) (also referred to as cloud radio access networks (C-RAN)) to facilitate scaling by decomposing base station functionality into multiple units that can be deployed independently.

[0054] Network nodes 110 of wireless communication network 100 may include one or more central units (CUs), one or more distributed units (DUs), and / or one or more radio units (RUs). CUs may host one or more higher-layer control functions, such as Radio Resource Control (RRC) functions, Packet Data Convergence Protocol (PDCP) functions, and / or Service Data Adaptation Protocol (SDAP) functions, etc. DUs may host one or more of the Radio Link Control (RLC) layer, Media Access Control (MAC) layer, and / or one or more higher physical (PHY) layers, at least in part, according to functional splits (such as those defined by 3GPP). In some examples, DUs may also host one or more low-PHY layer functions, such as Fast Fourier Transform (FFT), Inverse FFT (iFFT), beamforming, Physical Random Access Channel (PRACH) extraction and filtering, and / or scheduling of resources for one or more UEs 120, etc. RUs may host RF processing functions or low-PHY layer functions, such as FFT, iFFT, beamforming, or PRACH extraction and filtering, etc., according to functional splits (such as lower-layer functional splits). In this type of architecture, each RU can be operated to handle over-the-air (OTA) communications with one or more UE 120s.

[0055] In some aspects, a single network node 110 may include a combination of one or more CUs, one or more DUs, and / or one or more RUs. Additionally or alternatively, network node 110 may include one or more near real-time (near RT) RAN Intelligent Controllers (RICs) and / or one or more non-real-time (non-RT) RICs. In some examples, CUs, DUs, and / or RUs may be implemented as virtual units, such as Virtual Central Units (VCUs), Virtual Distributed Units (VDUs), or Virtual Radio Units (VRUs), etc. Virtual units may be implemented as virtual network functions, such as those associated with cloud deployments.

[0056] Some network nodes 110 (e.g., base stations, RUs, or TRPs) can provide communication coverage for specific geographic areas. In 3GPP, the term "cell" can refer to the coverage area of ​​network node 110 or to network node 110 itself, depending on the context in which the term is used. Network node 110 can support one or more (e.g., three) cells. In some examples, network node 110 can provide communication coverage for macro cells, pico cells, femto cells, or another type of cell. A macro cell can cover a relatively large geographic area (e.g., a radius of several kilometers) and can allow unrestricted access by UE 120 with a service subscription. A pico cell can cover a relatively small geographic area and can allow unrestricted access by UE 120 with a service subscription. A femto cell can cover a relatively small geographic area (e.g., a residential area) and can allow restricted access by UE 120 associated with that femto cell (e.g., UE 120 in a Closed Subscriber Group (CSG)). A network node 110 used for a macro cell may be referred to as a macro network node. Network node 110 used for a pico cell may be referred to as a pico network node. Network node 110 used for a femtocell may be referred to as a femto network node or a home network node. In some examples, the cell may not necessarily be stationary. For example, the geographical area of ​​the cell may be mobile based on the location of the associated mobile network node 110 (e.g., a train, satellite base station, unmanned aerial vehicle, or non-terrestrial network (NTN) network node).

[0057] The wireless communication network 100 can be a heterogeneous network, comprising different types of network nodes 110, such as macro network nodes, piconet nodes, femtonet nodes, relay network nodes, aggregation network nodes, and / or decomposition network nodes, etc. Figure 1 In the example shown, network node 110a can be a macro network node for macro cell 130a, network node 110b can be a pico network node for pico cell 130b, and network node 110c can be a femto network node for femto cell 130c. Compared to other types of network nodes 110, the various types of network nodes 110 typically transmit at different power levels, serve different coverage areas, and / or have different effects on interference in the wireless communication network 100. For example, macro network nodes may have high transmit power levels (e.g., 5 watts to 40 watts), while pico network nodes, femto network nodes, and relay network nodes may have lower transmit power levels (e.g., 0.1 watts to 2 watts).

[0058] In some examples, network node 110 may be, may include, or operate as a RU, TRP, or base station communicating with one or more UEs 120 via a radio access link (which may be referred to as a "Uu" link). The radio access link may include a downlink and an uplink. A "downlink" (or "DL") refers to the communication direction from network node 110 to UE 120, and an "uplink" (or "UL") refers to the communication direction from UE 120 to network node 110. Downlink channels may include one or more control channels and one or more data channels. Downlink control channels may be used to transmit downlink control information (DCI) (e.g., scheduling information, reference signals, and / or configuration information) from network node 110 to UE 120. Downlink data channels may be used to transmit downlink data (e.g., user data associated with UE 120) from network node 110 to UE 120. Downlink control channels may include one or more physical downlink control channels (PDCCH), and downlink data channels may include one or more physical downlink shared channels (PDSCH). The uplink channel may similarly include one or more control channels and one or more data channels. The uplink control channel can be used to transmit uplink control information (UCI) (e.g., reference signals and / or feedback corresponding to one or more downlink transmissions) from UE 120 to network node 110. The uplink data channel can be used to transmit uplink data (e.g., user data associated with UE 120) from UE 120 to network node 110. The uplink control channel may include one or more physical uplink control channels (PUCCH), and the uplink data channel may include one or more physical uplink shared channels (PUSCH). The downlink and uplink may each include a set of resources on which network node 110 and UE 120 can communicate.

[0059] Downlink and uplink resources may include time-domain resources (frames, subframes, time slots, and / or symbols), frequency-domain resources (bands, component carriers, subcarriers, resource blocks, and / or resource elements), and / or spatial-domain resources (specific transmission directions and / or beam parameters). Frequency-domain resources in some bands may be subdivided into bandwidth portions (BWPs). A BWP may be a contiguous block of frequency-domain resources allocated to one or more UEs 120 (e.g., a contiguous block of resource blocks). A UE 120 may be configured with both an uplink BWP and a downlink BWP (where the uplink BWP and downlink BWP may be the same BWP or different BWPs). BWPs may be dynamically configured and / or reconfigured (e.g., by sending DCI configuration to one or more UEs 120 via network node 110), meaning that BWPs may be adjusted in real-time (or near real-time) based on changing network conditions in the wireless communication network 100 and / or based on the specific requirements of one or more UEs 120. This allows for more efficient use of available frequency domain resources in the wireless communication network 100, as fewer frequency domain resources can be allocated to the BWP for UE 120 (which reduces the number of frequency domain resources that UE 120 needs to monitor), thus allowing more frequency domain resources to be distributed across multiple UE 120s. Therefore, the BWP can also assist in the implementation of such UE 120s by facilitating the configuration of smaller bandwidths for communications performed by lower-capacity UE 120s.

[0060] As described above, in some aspects, the wireless communication network 100 may be an IAB network, may include an IAB network, or may be included in an IAB network. In an IAB network, at least one network node 110 is an anchor network node communicating with a core network. The anchor network node 110 may also be referred to as an IAB donor (or "IAB donor"). The anchor network node 110 may be connected to the core network via a wired backhaul link. For example, the Ng interface of the anchor network node 110 may terminate at the core network. Additionally or alternatively, the anchor network node 110 may be connected to one or more devices in the core network that provide core access and mobility management functions (AMF). An IAB network typically also includes multiple non-anchor network nodes 110, which may also be referred to as relay network nodes or simply IAB nodes (or "IAB-nodes"). Each non-anchor network node 110 can directly communicate with the anchor network node 110 via a wireless backhaul link to access the core network, or can indirectly communicate with the anchor network node 110 via one or more other non-anchor network nodes 110 and an associated wireless backhaul link forming a backhaul path to the core network. Some anchor network nodes 110 or other non-anchor network nodes 110 can also directly communicate with one or more UEs 120 via a wireless access link carrying access services. In some examples, network resources used for wireless communication (such as time resources, frequency resources, and / or spatial resources) can be shared between the access link and the backhaul link.

[0061] In some examples, any network node 110 relaying communication may be referred to as a relay network node, a relay station, or simply a repeater. A repeater may receive communications from an upstream station (e.g., another network node 110 or UE 120) and transmit communications to a downstream station (e.g., UE 120 or another network node 110). In this case, the wireless communication network 100 may include or be referred to as a "multi-hop network." Figure 1 In the example shown, network node 110d (e.g., a relay network node) can communicate with network node 110a (e.g., a macro network node) and UE 120d to facilitate communication between network node 110a and UE 120d. Additionally or alternatively, UE 120 can be a relay station capable of relaying transmissions to or from other UE 120s, or can operate as such a relay station. UE 120 relaying communication can be referred to as a UE repeater or relay UE, etc.

[0062] UE 120 may be physically distributed throughout the wireless communication network 100, and each UE 120 may be stationary or mobile. UE 120 may be, may include, an access terminal, another terminal, a mobile station, or a subscriber unit, or may be included in an access terminal, another terminal, a mobile station, or a subscriber unit. UE 120 may be, or may include, a cellular phone (e.g., a smartphone), a personal digital assistant (PDA), a wireless modem, a wireless communication device, a handheld device, a laptop computer, a cordless phone, a wireless local loop (WLL) station, a tablet computer, a camera, a gaming device, a netbook, a smartbook, an ultrabook, a medical device, a biometric device, a wearable device (e.g., a smartwatch, smart clothing, smart glasses, a smart wristband and / or smart jewelry (such as a smart ring or smart bracelet)), an entertainment device (e.g., a music device, a video device and / or a satellite radio), an extended reality (XR) device, a vehicle component or sensor, a smart meter or sensor, industrial manufacturing equipment, a Global Navigation Satellite System (GNSS) device (such as a Global Positioning System device or another type of positioning device), a UE function of a network node, and / or any other suitable device or function that can communicate via a wireless medium, or may be coupled to them.

[0063] UE 120 and / or network node 110 may include one or more chips, system-on-a-chip (SoC), chipsets, packages, or devices that individually or collectively constitute or include a processing system. The processing system includes processor (or “processing”) circuitry in the form of one or more processors, microprocessors, processing units (such as central processing units (CPUs), graphics processing units (GPUs), neural processing units (NPUs), and / or digital signal processors (DSPs)), processing blocks, application-specific integrated circuits (ASICs), programmable logic devices (PLDs) (such as field-programmable gate arrays (FPGAs)), or other discrete gate or transistor logic components or circuits (all of which are generally referred to herein individually as “processors” or collectively as “processors” or “processor circuitry”). One or more of these processors may be individually or collectively configured to perform the various functions or operations described herein. A group of processors that can be configured or configured to perform a set of functions may include a first processor that can be configured or configured to perform a first function in the set, and a second processor that can be configured or configured to perform a second function in the set, or may include the entire group of processors that are configured or configured to perform the set of functions.

[0064] The processing system may also include memory circuitry in the form of one or more memory devices, memory blocks, memory elements, or other discrete gate or transistor logic components or circuits, each of which may include tangible storage media such as random access memory (RAM) or read-only memory (ROM) or combinations thereof (all of which are generally referred to herein individually as "memory" or collectively as "memory" or "memory circuitry"). One or more of these memories may be coupled to one or more processors in the processor (e.g., operatively coupled, communicatively coupled, electronically coupled, or electrically coupled) and may store processor-executable code (such as software) individually or collectively, which, when executed by one or more processors in the processor, may configure one or more processors in the processor to perform the various functions or operations described herein. Additionally or alternatively, in some examples, one or more processors in the processor may be pre-configured to perform the various functions or operations described herein without being configured by software. The processing system may also include or be coupled to one or more modems (such as Wi-Fi (e.g., IEEE compliant) modems or cellular (e.g., 3GPP 4G LTE, 5G, or 6G compliant) modems). In some embodiments, one or more processors of the processing system include or implement one or more modems among the modems. The processing system may also include, or be coupled to, multiple radio components (collectively, “radio components”), multiple RF chains, or multiple transceivers, each of which may in turn be coupled to one or more antennas among multiple antennas. In some embodiments, one or more processors of the processing system include or implement one or more of the radio components, RF chains, or transceivers. UE 120 may be included or may be contained in a housing that houses components associated with UE 120, including the processing system.

[0065] Some UEs 120 can be considered as Machine Type Communication (MTC) UEs, Evolved or Enhanced Machine Type Communication (eMTC) UEs, Further Enhanced eMTC (feMTC) UEs, or Enhanced feMTC (efeMTC) UEs, or further evolutions thereof, all of which can be simply referred to as "MTC UEs". An MTC UE can be, may include, or may be included in or coupled with the following: robots, unmanned aerial vehicles or drones, remote devices, sensors, instruments, monitors, and / or location tags. Some UEs 120 can be considered as IoT devices and / or can be implemented as NB-IoT (Narrowband IoT) devices. IoT UEs or NB-IoT devices can be, may include, or may be included in or coupled with the following: industrial machines, appliances, refrigerators, doorbell camera devices, home automation devices, and / or lighting fixtures, etc. Some UEs 120 may be considered customer premises equipment, which may include telecommunications equipment installed at a customer location (such as a home or office) to enable access to a service provider’s network (such as being included in or communicating with the wireless communication network 100).

[0066] Some UEs 120 can be categorized according to different categories associated with varying levels of complexity and / or capabilities. UEs 120 in the first category facilitate large-scale IoT within the wireless communication network 100 and offer lower complexity and / or cost compared to UEs 120 in the second category. UEs 120 in the second category may include mission-critical IoT devices capable of ultra-reliable low-latency communication (URLLC), enhanced mobile broadband (eMBB), and / or precise positioning within the wireless communication network 100; legacy UEs; baseline UEs; high-level UEs; advanced UEs; full-capability UEs; and / or premium UEs. UEs 120 in the third category may have intermediate-level complexity and / or capabilities (e.g., capabilities between first-category UEs 120 and second-capability UEs 120). UEs 120 in the third category may be referred to as reduced-capability UEs (“RedCap UEs”), intermediate-level UEs, NR lightweight UEs, and / or NR simplified UEs, etc. RedCap UEs bridge the gap in capabilities and complexity between NB-IoT devices and / or eMTC UEs and mission-critical IoT devices and / or premium UEs. RedCap UEs can include, for example, wearable devices, IoT devices, industrial sensors, and / or cameras associated with limited bandwidth, power capacity, and / or transmission range. RedCap UEs can support healthcare environments, building automation, power distribution, process automation, transportation and logistics, and / or smart city deployments, among others.

[0067] In some examples, two or more UEs 120 (e.g., shown as UE 120a and UE 120e) can communicate directly with each other using sidelink communication (e.g., without communicating through a network node 110 acting as an intermediary). As an example, UE 120a can send data, control information, or other signaling directly to UE 120e as sidelink communication. This contrasts with, for example, UE 120a first sending data to network node 110 in UL communication, and then that network node sending data to UE 120e in DL communication. In various examples, UE 120 can use peer-to-peer (P2P) communication protocols, device-to-device (D2D) communication protocols, vehicle-to-everything (V2X) communication protocols (which may include vehicle-to-vehicle (V2V) protocols, vehicle-to-infrastructure (V2I) protocols, and / or vehicle-to-pedestrian (V2P) protocols), and / or mesh network communication protocols to send and receive sidelink communication. In some deployments and configurations, network node 110 may schedule and / or allocate resources for sidelink communication between UEs 120 in the wireless communication network 100. In some other deployments and configurations, UE 120 (instead of network node 110) may perform or cooperate with or negotiate with one or more other UEs to perform scheduling operations, resource selection operations, and / or other operations for sidelink communication.

[0068] In various examples, in addition to half-duplex operation, some network nodes and UEs in the wireless communication network 100, including network node 110 and UE 120, can also be configured for full-duplex operation. Network node 110 or UE 120 operating in half-duplex mode can perform only one of transmission or reception during a specific time resource period (such as a specific time slot, symbol, or other time period). Half-duplex operation may involve time division duplex (TDD), where the DL transmission of network node 110 and the UL transmission of UE 120 do not occur in the same time resource (i.e., the transmissions do not overlap in time). In contrast, network node 110 or UE 120 operating in full-duplex mode can transmit and receive communications concurrently (e.g., within the same time resource). By operating in full-duplex mode, network node 110 and / or UE 120 can generally increase the capacity of the network and radio access links. In some examples, full-duplex operation may involve frequency division duplex (FDD), in which network node 110 performs DL transmission in a first frequency band or on a first component carrier, and UE 120 performs transmission in a second frequency band or on a second component carrier, the second frequency band or the second component carrier being different from the first frequency band or the first component carrier, respectively. In some examples, full-duplex operation may be enabled for UE 120 but not for network node 110. For example, UE 120 may simultaneously transmit UL to the first network node 110 and receive DL transmissions from the second network node 110 in the same time resources. In some other examples, full-duplex operation may be enabled for network node 110 but not for UE 120. For example, network node 110 may simultaneously transmit DL to the first UE 120 and receive UL transmissions from the second UE 120 in the same time resources. In some other examples, full-duplex operation may be enabled for both network node 110 and UE 120.

[0069] In some examples, UE 120 and network node 110 can perform MIMO communication. "MIMO" generally refers to the simultaneous transmission or reception of multiple signals (such as multiple layers or multiple data streams) using the same time and frequency resources. MIMO techniques typically utilize multipath propagation. MIMO can be implemented using various spatial processing or spatial multiplexing operations. In some examples, MIMO can support simultaneous transmission to multiple receivers, which is called multi-user MIMO (MU-MIMO). Some RATs can employ advanced MIMO techniques such as mTRP operations (including redundant transmission or reception on multiple TRPs), reciprocity in the time or frequency domain, single-frequency network (SFN) transmission, or noncoherent joint transmission (NC-JT).

[0070] In some aspects, UE 120 may include a communications manager 140. As described in more detail elsewhere herein, communications manager 140 may transmit information indicating a maximum number of aperiodic tracking reference signals for CSI reporting based on resource configuration; and receive one or more aperiodic tracking reference signals based on that maximum number of aperiodic tracking reference signals. Additionally or alternatively, communications manager 140 may perform one or more other operations described herein.

[0071] In some respects, network node 110 may include communication manager 150. As described in more detail elsewhere herein, communication manager 150 may receive information indicating a maximum number of aperiodic tracking reference signals for CSI reporting based on resource configuration; and transmit one or more aperiodic tracking reference signals based on that maximum number of aperiodic tracking reference signals. Additionally or alternatively, communication manager 150 may perform one or more other operations described herein.

[0072] In some aspects, UE 120 may include a communication manager 140. As described in more detail elsewhere herein, the communication manager 140 may generate a parameter indicating the number of channel state information reference signal timings supported by the UE based on periodic channel state information reference signal configuration; calculate a CSI timeline indicator based on the parameter; and send at least one of an indication to the parameter or an indication to the CSI timeline indicator. Additionally or alternatively, the communication manager 140 may perform one or more other operations described herein.

[0073] In some aspects, network node 110 may include communication manager 150. As described in more detail elsewhere herein, communication manager 150 may receive a parameter indicating the number of channel state information reference signal timings supported by the UE based on periodic channel state information reference signals; receive an indication of a CSI timeline indicator based on the parameter; and transmit one or more channel state information reference signals based on the parameter or the CSI timeline indicator. Additionally or alternatively, communication manager 150 may perform one or more other operations described herein.

[0074] Figure 2 This is a diagram illustrating communication between an example network node 110 and an example UE 120 in a wireless network according to the present disclosure.

[0075] like Figure 2As shown, network node 110 may include a data source 212, a transmit processor 214, a transmit (TX) MIMO processor 216, a set of modems 232 (shown as 232a to 232t, where t≥1), a set of antennas 234 (shown as 234a to 234v, where v≥1), a MIMO detector 236, a receive processor 238, a data sink 239, a controller / processor 240, a memory 242, a communication unit 244, a scheduler 246, and / or a communication manager 150, etc. In some configurations, one or a combination of antennas 234, modems 232, MIMO detectors 236, receive processors 238, transmit processors 214, and / or TX MIMO processors 216 may be included in the transceiver of network node 110. The transceiver may be under the control of and used by one or more processors (such as controller / processor 240), and in some respects, may perform aspects of the methods, procedures and / or operations described herein in conjunction with processor-readable code stored in memory 242. In some respects, network node 110 may include one or more interfaces, communication components and / or other components that facilitate communication with UE 120 or another network node.

[0076] The terms “processor,” “controller,” or “controller / processor” can refer to one or more controllers and / or one or more processors. For example, references to “a / the processor,” “a / the controller / processor,” etc. (in the singular) should be understood as referring to a combination of… Figure 2 The processor described refers to any one or more processors, such as a single processor or a combination of multiple different processors. The reference to "one or more processors" should be understood as referring to a combination of... Figure 2 Any one or more processors described herein. For example, one or more processors of network node 110 may include transmit processor 214, TX MIMO processor 216, MIMO detector 236, receive processor 238, and / or controller / processor 240. Similarly, one or more processors of UE 120 may include MIMO detector 256, receive processor 258, transmit processor 264, TX MIMO processor 266, and / or controller / processor 280.

[0077] In some aspects, a single processor can perform all operations described as being performed by one or more processors. In some aspects, a first set of one or more processors can perform a first operation described as being performed by that one or more processors, and a second set of one or more processors can perform a second operation described as being performed by that one or more processors. The processors in the first set and the processors in the second set can be the same set of processors or can be different sets of processors. The reference to "one or more memories" should be understood to mean any one or more memories of the corresponding device, such as combined... Figure 2 The memory described. For example, an operation described as being performed by one or more memories can be performed by the same subset of the one or more memories or by different subsets of the one or more memories.

[0078] For downlink communication from network node 110 to UE 120, transmitting processor 214 may receive data (“downlink data”) intended for use by UE 120 (or a set of UEs including UE 120) from data source 212 (such as a data pipeline or data queue). In some examples, transmitting processor 214 may select one or more MCSs for UE 120 based on one or more Channel Quality Indicators (CQIs) received from UE 120. Network node 110 may process the data (e.g., including encoding the data) based on the MCS selected for UE 120 for transmission to UE 120 on the downlink, thereby generating data symbols. Transmitting processor 214 may process system information (e.g., semi-static resource partitioning information (SRPI)) and / or control information (e.g., CQI requests, grants, and / or upper-layer signaling) and provide overhead symbols and / or control symbols. The transmitting processor 214 can generate reference symbols for reference signals (e.g., cell-specific reference signal (CRS), demodulation reference signal (DMRS), or CSI-RS) and / or synchronization signals (e.g., primary synchronization signal (PSS) or secondary synchronization signal (SSS)).

[0079] The TX MIMO processor 216 can perform space processing (e.g., pre-decoding) on ​​data symbols, control symbols, overhead symbols, and / or reference symbols where applicable, and can output a set of symbol streams (e.g., TA set of output symbol streams is provided to modem 232. For example, each output symbol stream may be provided to a corresponding modulator component (shown as MOD) of modem 232. Each modem 232 may use the corresponding modulator component to process (e.g., modulate) the corresponding output symbol stream (e.g., for orthogonal frequency division multiplexing (OFDM)) to obtain an output sample stream. Each modem 232 may further use the corresponding modulator component to process (e.g., convert to analog, amplify, filter, and / or upconvert) the output sample stream to obtain a time-domain downlink signal. Modems 232a to 232t may transmit the set of downlink signals (e.g., [missing information]) together via a set of corresponding antennas 234. T (One downlink signal).

[0080] Downlink signals may include DCI communication, MAC control element (MAC-CE) communication, RRC communication, downlink reference signals, or another type of downlink communication. Downlink signals may be transmitted on the PDCCH, PDSCH, and / or another downlink channel. Downlink signals may carry one or more transport blocks (TBs) of data. A TB may be a data unit transmitted via the air interface in the wireless communication network 100. A data stream (e.g., from data source 212) may be encoded into multiple TBs for transmission via the air interface. The number of TBs used to carry data associated with a particular data stream may be associated with a TB size shared by multiple TBs. The TB size may be based on the radio channel conditions of the air interface, the MCS used to encode the data, downlink resources allocated for transmitting data, and / or other parameters, or otherwise associated with them. Generally, a larger TB size allows for a larger amount of data to be transmitted in a single transmission, reducing signaling overhead. However, a larger TB size may be more prone to transmission and / or reception errors than a smaller TB size, but such errors can be mitigated through more robust error correction techniques.

[0081] For uplink communication from UE 120 to network node 110, the uplink signal from UE 120 may be received by antenna 234, processed by modem 232 (e.g., demodulator component of modem 232, shown as DEMOD), detected where applicable by MIMO detector 236 (e.g., receive (Rx) MIMO processor), and / or further processed by receive processor 238 to obtain decoded data and / or control information. Receive processor 238 may provide the decoded data to data sink 239 (which may be a data pipeline, data queue, and / or another type of data sink) and provide the decoded control information to processors such as controller / processor 240.

[0082] Network node 110 may use scheduler 246 to schedule one or more UEs 120 for downlink or uplink communication. In some aspects, scheduler 246 may use DCI to dynamically schedule DL transmissions to and / or UL transmissions from UE 120. In some examples, scheduler 246 may allocate repetitive time-domain and / or frequency-domain resources that UE 120 may use to transmit and / or receive communication using RRC configuration (e.g., semi-static configuration), for example, to perform semi-persistent scheduling (SPS) or to configure configuration grant (CG) for UE 120.

[0083] One or more of the following may be included in the RF chain of network node 110: transmit processor 214, TX MIMO processor 216, modem 232, antenna 234, MIMO detector 236, receive processor 238, and / or controller / processor 240. The RF chain may include one or more filters, mixers, oscillators, amplifiers, analog-to-digital converters (ADCs), and / or other devices for converting analog signals (such as those used for transmission or reception via an air interface) to digital signals (such as those used for processing by one or more processors of network node 110). In some aspects, the RF chain may be a transceiver of network node 110, or may be included in such a transceiver.

[0084] In some examples, network node 110 may use communication unit 244 to communicate with the core network and / or other network nodes. Communication unit 244 may support wired and / or wireless communication protocols and / or connections, such as Ethernet, fiber optic, Common Public Radio Interface (CPRI), and / or wired or wireless backhaul, etc. Network node 110 may use communication unit 244 to send and / or receive data associated with UE 120, or to perform network control signaling, etc. Communication unit 244 may include transceivers and / or interfaces, such as network interfaces.

[0085] UE 120 may include a set of antennas 252 (shown as antennas 252a to 252r, where r ≥ 1), a set of modems 254 (shown as modems 254a to 254u, where u ≥ 1), a MIMO detector 256, a receive processor 258, a data sink 260, a data source 262, a transmit processor 264, a TX MIMO processor 266, a controller / processor 280, a memory 282, and / or a communication manager 140, etc. One or more components of UE 120 may be included in housing 284. In some aspects, one or a combination of antenna 252, modem 254, MIMO detector 256, receive processor 258, transmit processor 264, or TX MIMO processor 266 may be included in a transceiver included in UE 120. The transceiver may be under the control of and used by one or more processors (such as controller / processor 280), and in some respects, may perform aspects of the methods, procedures, or operations described herein in conjunction with processor-readable code stored in memory 282. In some respects, UE 120 may include another interface, another communication component, and / or another component that facilitates communication with network node 110 and / or another UE 120.

[0086] For downlink communication from network node 110 to UE 120, the set of antennas 252 can receive downlink communication or signals from network node 110, and can transmit the set of received downlink signals (e.g., R Each received signal is provided to a set of modems 254. For example, each received signal may be provided to a corresponding demodulator component (shown as DEMOD) of modem 254. Each modem 254 may use the corresponding demodulator component to condition (e.g., filter, amplify, down-convert, and / or digitize) the received signal to obtain an input sample. Each modem 254 may use the corresponding demodulator component to further demodulate or process the input sample (e.g., for OFDM) to obtain a received symbol. MIMO detector 256 may obtain the received symbols from the set of modems 254, may perform MIMO detection on the received symbols where applicable, and may provide the detected symbols. Receiver processor 258 may process (e.g., decode) the detected symbols, may provide the decoded data for UE 120 to data sink 260 (which may include a data pipeline, data queue, and / or an application executed on UE 120), and may provide the decoded control information and system information to controller / processor 280.

[0087] For uplink communication from UE 120 to network node 110, the transmitting processor 264 may receive and process data (“uplink data”) from data source 262 (such as a data pipeline, data queue, and / or an application running on UE 120) and control information from controller / processor 280. The control information may include one or more parameters, feedback, one or more signal measurements, and / or other types of control information. In some aspects, the receiving processor 258 and / or controller / processor 280 may determine one or more parameters related to the transmission of uplink communication for received signals (such as those received from network node 110 or another UE). These one or more parameters may include a Reference Signal Received Power (RSRP) parameter, a Received Signal Strength Indicator (RSSI) parameter, a Reference Signal Received Quality (RSRQ) parameter, a Channel Quality Indicator (CQI) parameter, or a Transmit Power Control (TPC) parameter, etc. The control information may include indications of the RSRP parameter, RSSI parameter, RSRQ parameter, CQI parameter, TPC parameter, and / or another parameter. Control information can facilitate parameter selection and / or scheduling for UE 120 by network node 110.

[0088] Transmitter 264 can generate reference symbols for one or more reference signals, such as uplink DMRS, uplink sounding reference signal (SRS), and / or another type of reference signal. Symbols from transmitter 264 can (where applicable) be pre-decoded by TX MIMO processor 266 and further processed by an assembly of modems 254 (e.g., for DFT-s-OFDM or CP-OFDM). TX MIMO processor 266 can (where applicable) perform spatial processing (e.g., pre-decoding) on ​​data symbols, control symbols, overhead symbols, and / or reference symbols, and can provide an output symbol stream set (e.g., ...) to the assembly of modems 254. U Each output symbol stream may be provided to a corresponding modulator component (shown as MOD) of modem 254. Each modem 254 may use the corresponding modulator component to process (e.g., modulate) the corresponding output symbol stream (e.g., for OFDM) to obtain an output sample stream. Each modem 254 may further use the corresponding modulator component to process (e.g., convert to analog, amplify, filter, and / or upconvert) the output sample stream to obtain an uplink signal.

[0089] Modems 254a to 254u can transmit sets of uplink signals (e.g., via corresponding sets of antennas 252) R One uplink signal or UUplink signals may include UCI communication, MAC-CE communication, RRC communication, or another type of uplink communication. Uplink signals may be transmitted on PUSCH, PUCCH, and / or another type of uplink channel. Uplink signals may carry one or more TBs of data. Sidelink data and control transmission (i.e., transmission directly between two or more UEs 120) may typically use techniques similar to those described for uplink data and control transmission, and may use sidelink-specific channels such as the Physical Sidelink Shared Channel (PSSCH), Physical Sidelink Control Channel (PSCCH), and / or Physical Sidelink Feedback Channel (PSFCH).

[0090] One or more antennas in the set of antennas 252 or the set of antennas 234 may include one or more antenna panels, one or more antenna groups, one or more sets of antenna elements, or one or more antenna arrays, etc., or may be included in one or more antenna panels, one or more antenna groups, one or more sets of antenna elements, or one or more antenna arrays, etc. Antenna panels, antenna groups, sets of antenna elements, or antenna arrays may include one or more antenna elements (within a single housing or multiple housings), a set of coplanar antenna elements, a set of non-coplanar antenna elements, or with one or more transmitting or receiving components (such as...) Figure 2 An antenna module is a combination of one or more antenna elements coupled to one or more components. As used herein, "antenna" can mean one or more antennas, one or more antenna panels, one or more antenna groups, one or more collections of antenna elements, or one or more antenna arrays. "Antenna panel" can mean a group of antennas (such as antenna elements) arranged in an array or panel that can facilitate beamforming by manipulating the parameters of that group of antennas. "Antenna module" can mean a circuit that includes one or more antennas, and may also include one or more other components (such as filters, amplifiers, or processors) associated with integrating the antenna module into a wireless communication device.

[0091] In some examples, each antenna element of antenna 234 or antenna 252 may include one or more sub-elements for radiating or receiving radio frequency signals. For example, a single antenna element may include a first sub-element cross-polarized with a second sub-element, which can be used to independently transmit cross-polarized signals. Antenna elements may include patch antennas, dipole antennas, and / or other types of antennas arranged in a linear pattern, a two-dimensional pattern, or another pattern. The spacing between antenna elements can allow signals with a desired wavelength transmitted individually by the antenna elements to interact or interfere (e.g., to form a desired beam) in various directions. For example, given a desired wavelength or frequency range, the spacing may provide a quarter wavelength, half a wavelength, or another fraction of the wavelength between adjacent antenna elements to allow desired constructive and destructive interference modes of signals transmitted by individual antenna elements within that desired range.

[0092] The amplitude and / or phase of signals transmitted via antenna elements and / or sub-elements can be modulated and (e.g., by manipulating phase shifts, phase offsets, and / or amplitudes) shifted relative to each other to generate one or more beams; this is known as beamforming. The term "beam" can refer to the directional transmission of a wireless signal toward a receiving device or otherwise in a desired direction. "Beam" can also generally refer to the direction associated with such directional signal transmission, the set of directional resources associated with the signal transmission (e.g., angle of arrival, horizontal direction, and / or vertical direction), and / or a set of parameters indicating one or more aspects of the directional signal, the direction associated with the signal, and / or the set of directional resources associated with the signal. In some implementations, antenna elements can be individually selected or deselected for the directional transmission of a signal (or multiple signals) by controlling the amplitude of one or more corresponding amplifiers and / or the phase of the signal to form one or more beams. The shape of the beam (such as amplitude, width, and / or the presence of sidelobes) and / or the direction of the beam (such as the angle of the beam relative to the surface of the antenna array) can be dynamically controlled by modifying the phase shifts, phase offsets, and / or amplitudes of multiple signals relative to each other.

[0093] Different UEs 120 or network nodes 110 may include different numbers of antenna elements. For example, UE 120 may include a single antenna element, two antenna elements, four antenna elements, eight antenna elements, or different numbers of antenna elements. Similarly, network node 110 may include eight antenna elements, 24 antenna elements, 64 antenna elements, 128 antenna elements, or different numbers of antenna elements. Generally speaking, a larger number of antenna elements provides increased control over the parameters used for beamforming compared to a smaller number of antenna elements, while a smaller number of antenna elements may be less complex to implement and can use less power. Multiple antenna elements can support multi-layer transmission, in which the same time and frequency resources are used to spatially multiplex a first layer of communication (which may include a first data stream) and a second layer of communication (which may include a second data stream).

[0094] Figure 3 This is an illustration of an example disaggregated base station architecture 300 according to the present disclosure. One or more components of the example disaggregated base station architecture 300 may be one or more network nodes (such as one or more network nodes 110), may include, or may be included in, the one or more network nodes. The disaggregated base station architecture 300 may include a CU 310, which may communicate directly with the core network 320 via a backhaul link, or may communicate indirectly with the core network 320 via one or more disaggregated control units (such as non-RT RIC 350 and / or near-RT RIC 325 (e.g., via an E2 link) associated with a Service Management and Orchestration (SMO) framework 360). The CU 310 may communicate with one or more DUs 330 via a corresponding midhaul link (such as via an F1 interface). Each DU in the DU 330 may communicate with one or more RUs 340 via a corresponding fronthaul link. Each RU in the RU 340 may communicate with one or more UEs 120 via a corresponding RF access link. In some deployments, UE 120 can be served by multiple RU 340s simultaneously.

[0095] Each component of the disassembled base station architecture 300 (including CU 310, DU 330, RU 340, near-RT RIC 370, non-RT RIC 350, and SMO frame 360) may include one or more interfaces or may be coupled to one or more interfaces for receiving or transmitting signals, such as data or information, via wired or wireless transmission media.

[0096] In some respects, the CU 310 can be logically divided 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 bidirectionally with the CU-CP units via an interface such as an E1 interface. The CU 310 can be deployed to communicate with one or more DU 330s for network control and signaling, as needed. Each DU 330 may correspond to a logical unit that includes one or more base station functions for controlling the operation of one or more RU 340s. For example, the DU 330 may host various layers, such as the RLC layer, MAC layer, or one or more PHY layers (such as one or more high PHY layers or one or more low PHY layers). Each layer (which may also be referred to as a module) can be implemented using an interface for signaling to other layers (and modules) hosted by the DU 330, or for signaling to control functions hosted by the CU 310. Each RU 340 may implement lower-layer functionality. In some respects, the real-time and non-real-time aspects of communication with the control plane and user plane of the RU 340 can be controlled by the corresponding DU 330.

[0097] The SMO framework 360 supports RAN deployment and provisioning for both non-virtualized and virtualized network elements. For non-virtualized network elements, the SMO framework 360 supports the deployment of dedicated physical resources for RAN coverage requirements, which can be managed via operation and maintenance interfaces such as the O1 interface. For virtualized network elements, the SMO framework 360 can interact with cloud computing platforms such as the Open Cloud (O-Cloud) platform 390 to perform network element lifecycle management (such as instantiating virtualized network elements) via cloud computing platform interfaces such as the O2 interface. Virtualized network elements may include, but are not limited to, CU 310, DU 330, RU 340, non-RT RIC 350, and / or near-RT RIC 370. In some aspects, the SMO framework 360 can communicate with hardware aspects of the 4G RAN, 5G NR RAN, and / or 6G RAN (such as the Open eNB (O-eNB) 380) via the O1 interface. Additionally or alternatively, the SMO framework 360 can communicate directly with each of one or more RUs 340 via the corresponding O1 interface. In some deployments, this configuration enables each DU 330 and CU 310 to be implemented in a cloud-based RAN architecture, such as a vRAN architecture.

[0098] The non-RT RIC 350 may include or implement logical functions that enable non-real-time control and optimization of RAN elements and resources, including artificial intelligence / machine learning (AI / ML) workflows for model training and updates, and / or policy-based guidance of applications and / or features in the near-RT RIC 370. The non-RT RIC 350 may be coupled to or communicate with the near-RT RIC 370, such as via an A1 interface. The near-RT RIC 370 may include or implement logical functions that enable near real-time control and optimization of RAN elements and resources via an interface, such as via an E2 interface, through data collection and action, connecting one or more CU 310s, one or more DU 330s, and / or O-eNBs to the near-RT RIC 370.

[0099] In some aspects, to generate AI / ML models to be deployed in the near-RT RIC 370, the non-RT RIC 350 may receive parameters or external enrichment information from an external server. This information can be utilized by the near-RT RIC 370 and can be received from non-network data sources or network functions at the SMO framework 360 or the non-RT RIC 350. In some examples, the non-RT RIC 350 or near-RT RIC 370 may modulate RAN behavior or performance. For example, the non-RT RIC 350 may monitor long-term trends and patterns in performance and may employ AI / ML models to perform corrective actions via the SMO framework 360 (such as reconfiguration via the O1 interface) or via the creation of RAN management policies (such as A1 interface policies).

Memory 242 may include one or more memories, such as a single memory or multiple different memories (of the same or different types). Memory 282 may include one or more memories, such as a single memory or multiple different memories (of the same or different types). For example, the set of instructions may be executed by one or more processors of network node 110, UE 120, CU 310, DU 330, or RU 340 (e.g., directly, or after compilation, transformation, or interpretation).

In some examples, the execution instructions may include run instructions, transform instructions, compile instructions, and / or interpret instructions, etc.

[0101] In some aspects, UE 120 includes components for transmitting information indicating a maximum number of aperiodic tracking reference signals (CSI) reported according to resource configuration; and / or components for receiving one or more aperiodic tracking reference signals based on such maximum number. Components for UE 120 to perform the operations described herein may include, for example, one or more of the following: communication manager 140, antenna 252, modem 254, MIMO detector 256, receive processor 258, transmit processor 264, TX MIMO processor 266, controller / processor 280, or memory 282.

[0102] In some aspects, network node 110 includes components for receiving information indicating a maximum number of aperiodic tracking reference signals for CSI reporting based on resource configuration; and / or components for transmitting one or more aperiodic tracking reference signals based on the maximum number of aperiodic tracking reference signals. Components for enabling network node 110 to perform the operations described herein may include, for example, one or more of the following: communication manager 150, transmit processor 220, TX MIMO processor 230, modem 232, antenna 234, MIMO detector 236, receive processor 238, controller / processor 240, memory 242, or scheduler 246.

[0103] In some aspects, UE 120 includes components for generating a parameter indicating the number of channel state information reference signal timings supported by the UE according to the periodic channel state information reference signal configuration; components for calculating a CSI timeline indicator based on the parameter; and / or components for transmitting at least one of an indication of the parameter or an indication of the CSI timeline indicator. Components for UE 120 to perform the operations described herein may include, for example, one or more of a communication manager 140, an antenna 252, a modem 254, a MIMO detector 256, a receive processor 258, a transmit processor 264, a TX MIMO processor 266, a controller / processor 280, or a memory 282.

Components for the network node to perform the operations described herein may include, for example, one or more of the following: communication manager 150, transmit processor 220, TX MIMO processor 230, modem 232, antenna 234, MIMO detector 236, receive processor 238, controller / processor 240, memory 242, or scheduler 246.

[0105] Figure 4 This is a diagram illustrating Example 400 of a time-domain channel attribute report according to this disclosure.

[0106] The communication channel may vary over time based on one or more conditions. For example, the channel may vary based on Doppler conditions, obstruction conditions, interference conditions, weather conditions, or UE mobility conditions, etc. The temporal variability of the channel indicates the rate at which the channel changes over time. In some cases, the temporal variability of the channel used for communication between network node 110 and UE 120 may be based on or otherwise associated with a CSI-RS used for tracking reference signals (TRS). For example, UE 120 may receive a TRS from network node 110, perform one or more measurements using the TRS, and send a time-domain channel attribute (TDCP) report indicating the temporal variability of the channel based on the one or more TRS measurements to network node 110.

[0107] TDCP reports may be based on or otherwise associated with multiple TRS resource sets. For example, TDCP reports may be based on or associated with TRS resource sets 405 and 410, or otherwise associated with these TRS resource sets. TDCP reports can be used, for example, to assist network node 110 in identifying CSI codebook handover information, to assist network node 110 in using the CSI reported by the UE (compared to the probe reference signal), to assist network node 110 in identifying CSI-RS or SRS resource periodicity, and / or to assist network node 110 in identifying demodulation reference signal (DMRS) time density. In some cases, UE 120 and / or network node 110 may identify the delay (D1) between a first TRS resource included in TRS resource set 405 and a first TRS resource included in second TRS resource set 405, the delay (D2) between a first TRS resource included in a first time slot associated with TRS resource set 405 and a first TRS resource included in a second time slot associated with TRS resource set 405, and / or the delay (D3) between a first TRS resource included in a time slot associated with TRS resource set 405 and the last TRS resource included in the same time slot associated with TRS resource set 405. For example, UE 120 and / or network node 110 may identify D1 as five time slots, D2 as one time slot, and D3 as four symbols. In some cases, UE 120 may report the normalized amplitude (with or without phase) of the time-related curve according to the following: ,in A It is the (normalized) amplitude; t It is a time indicator; D It is a delay indicator (e.g., D1); c It is a parameter; k It is a frequency index; and It is a subcarrier Channel measurements at the location.

[0108] In some cases, the normalized amplitude can be based on the following arithmetic mean: .

[0109] In some other cases, the normalized amplitude can be based on the following geometric mean: .

[0110] In some cases, the calculation results may be averaged across multiple resource pairs and / or across multiple receiver ports. In some cases, the measurement resource may be associated with one or more single-port CSI-RS resources following TRS mode. Additionally, multiple resource sets may support a value of D (e.g., D1) greater than or equal to two time slots. In some cases, D1 may be referred to as the cross-set delay.

[0111] In some cases, TDCP may have the following characteristics: a delay equal to one ( Y () Y = 1) number, less than or equal to the parameter D basic Delay ( D )(For example, D1 )(in D basic Equal to four symbols or one time slot), equal to one resource set ( K TRS () K TRS = 1), and can be used to report broadband normalized amplitude. In some other cases, TDCP may (additionally or alternatively) have the following properties: a delay equal to 2, 3, or 4 ( Y The number of integers (e.g., {2, 3, 4}) is greater than the parameter. D basic Delay, D (For example, D1 The candidate values ​​for ) are D = {2, 3, 4, 5, 6, 10} time slots, a resource set equal to two or three ( K TRS = {2, 3}) and can be used for phase reporting. In some cases, delays of ten slots can be supported only for subcarrier spacing (SCS) greater than or equal to thirty kHz (e.g., to ensure delays are less than ten milliseconds (ms)), and delays of six or ten slots can be supported by separate UE feature groups. In some cases, a resource set of three can support four delays with two intra-set delays (four symbols, one slot) and two cross-set delays (greater than or equal to two slots).

[0112] Figure 5 These are illustrations of examples 500 and 505 of the Doppler report according to this disclosure.

[0113] The communication signal between UE 120 and network node 110 may experience the Doppler effect. The Doppler effect can occur, for example, when the frequency of the communication signal changes due to relative motion between the transmitter and receiver (such as UE 120 and network node 110). The Doppler effect can be based on Type I Doppler or Type II Doppler, or otherwise associated with them. Type I Doppler can occur based on rapid and / or random motion between the transmitter and receiver. In some cases, this may be a result of objects or obstacles interfering with the communication path of the communication signal, and may cause small-scale attenuation corresponding to rapid fluctuations in the amplitude and / or phase of the communication signal. In contrast, Type II Doppler can occur based on slower and / or more predictable motion between the transmitter and receiver. In some cases, this may be a result of UE 120 moving within the coverage area of ​​network node 110, and may cause large-scale attenuation.

[0114] As shown in Example 500, UE 120 can receive multiple CSI-RS transmissions 510 and can perform one or more PUSCH transmissions 515. The window used for CSI reporting ( W CSI It can have a start time slot ( l The starting time slot is based on the time slot. n and parameters δ The product or otherwise associated with that product ( l = n + δ ),in n Associated with the time slot used for PUSCH transmission 515, and δ It is defined based on the number of CSI-RS transmissions or otherwise associated with that number of CSI-RS transmissions (e.g., In some cases, Traditional CSI reference resource slots (e.g., slots) can be used. n (The previous 4 or 5 time slots). In some cases, it can be... The window size is defined as follows: Window size ,in It is the Doppler length. ,and It is the time granularity (time unit), and Time slot.

[0115] In some cases, the Channel Quality Indicator (CQI) can be defined in the time domain. In some examples, UE 120 can be based on... W CSI The starting time slot lTo use a single CQI in the time domain. In some other examples, the UE can use the starting time slot. l and the end gap l + W CSI – 1. Take the average to use a single CQI in the time domain, or it can be based on the starting time slot. l and intermediate time slots l + ( W CSI / 2) Use two CQIs in the time domain. The second CQI may include a wideband and subband indication, and the two CQIs can be encoded separately (without difference).

[0116] Channel Measurement Reports (CMRs) can be sent from UE 120 to network node 110 and can indicate one or more channel measurements associated with the channel used for communication between UE 120 and network node 110. In some cases, aperiodic CSI-RS bursts may include K One resource, of which K = {4,8,12}. As shown in Example 505, UE 120 can receive multiple CSI-RS 510 and can perform PUSCH transmission 515 (e.g., in a time slot). n (in the middle), and can receive PDCCH transmissions 520. The distance between each CSI-RS 510 can be defined as m, where m = 2. The example timeline for communication shown in Example 505 is illustrated in Table 1, where... Z2 and Z2' For example, it is defined in Table 5.4-2 of 3GPP specification 38.214 version 15.2.0.

[0117] Table 1

[0118] In some cases, the UE can have a number ( O CPU The occupied CSI resources are used to perform Doppler measurements. However, in various examples, the number of occupied CSI resources to be used for performing Doppler measurements may conflict. In the first example for high-speed or medium-speed Type II codebook refinement, the number of occupied CSI resources can be [missing information] when periodic or semi-persistent CSI-RS is configured for channel measurement reporting. O CPU = Y N 4 Alternatively, it can be used when aperiodic CSI-RS is configured for channel measurement reporting. OCPU = Y K In this example, Y ≥ 1 is defined based on UE capabilities and can vary between periodic or semi-persistent CSI-RS and aperiodic CSI-RS. In some cases, when N 4 When = 1, O CPU = 4. Alternatively, when periodic or semi-persistent CSI-RS is configured for channel measurement reporting, O CPU ≥ 4. However, in the second example of the refinement of the Type II codebook for high-speed or medium-speed applications, regarding CPU usage... Y Candidate values ​​for Y can be {2 / 3, 1, 2, 3}. Therefore, in the first and second examples, candidate values ​​for Y may conflict, which could lead to inconsistent CSI resource usage for performing Doppler measurements.

[0119] Figure 6 This is a diagram illustrating example 600 of non-periodic tracking reference signal capability information according to this disclosure.

[0120] In operation 605, UE 120 may send, and network node 110 may receive, information indicating the maximum number of aperiodic tracking reference signals used for CSI reporting. This maximum number of tracking reference signals may be based on multiple CSI-RS resources associated with resource configuration. In some aspects, sending the information indicating the maximum number of aperiodic tracking reference signals may include sending UE capability information indicating the maximum number of aperiodic tracking reference signals.

[0121] In some respects, information indicating the maximum number of non-periodic tracking reference signals can indicate the CSI measurement configuration. CSI-MeasConfig One or more configuration limitations in ). In the first example, sending information indicating the maximum number of aperiodic tracking reference signals may include capability information indicating the maximum number of aperiodic tracking reference signals configured at the UE. For example, information indicating the maximum number of aperiodic tracking reference signals may indicate having configured TRS information ( trs-Info ) and non-periodic trigger offset ( aperiodicTriggeringOffset The non-zero power CSI-RS resource set ( NZP-CSI-RS-ResourceSet The maximum number of indicators can be configured. Additionally or alternatively, information indicating the maximum number of non-periodic tracking reference signals can indicate the configured TRS information associated with the TDCP report config. trs-Info ) and non-periodic trigger offset ( aperiodicTriggeringOffsetThe non-zero power CSI-RS resource set ( NZP-CSI-RS-ResourceSet The maximum number of indicators can be configured. In some aspects, capability information indicating the maximum number of aperiodic tracking reference signals configured at the UE can be applied to a single component carrier. In other aspects, capability information indicating the maximum number of aperiodic tracking reference signals configured at the UE can be applied across all component carriers. In a second example, sending information indicating the maximum number of aperiodic tracking reference signals may include sending capability information indicating the maximum number of TDCP reporting settings configured at the UE. For example, information indicating the maximum number of TDCP reporting settings may indicate the number of reports configured as TDCP (…). reportQuantity CSI report configuration () CSI- ReportConfig The maximum number of configurations for TDCP reports. In some aspects, capability information indicating the maximum number of TDCP reports can be applied to each bandwidth segment. In some aspects, capability information indicating the maximum number of TDCP reports can be applied (separately) to each of multiple component carriers. In some other aspects, capability information indicating the maximum number of TDCP reports can be applied across all component carriers.

[0122] In some examples of TRS-based TDCP reports, the number of configured TRS resource sets ( K TRS The support value can be one, two, or three. K TRS = {1,2,3}). Candidate values ​​for two and three can be optional. In some aspects, UE 120 may send, and network node 110 may receive, an indication of whether UE 120 supports reporting a single aperiodic tracking reference signal per report. For example, UE 120 may send a capability parameter indicating whether UE 120 supports reporting a single aperiodic tracking reference signal per report. Additionally or alternatively, UE 120 may send, and network node 110 may receive, an indication of whether UE 120 supports reporting more than one (e.g., two or three) tracking reference signals per report. For example, UE 120 may send a capability parameter indicating the number of periodic tracking reference signals configured per report, and may send another capability parameter indicating the number of aperiodic tracking reference signals configured per report.

[0123] In operation 610, network node 110 may transmit one or more aperiodic tracking reference signals based on the maximum number of aperiodic tracking reference signals, and UE 120 may receive one or more aperiodic tracking reference signals based on the maximum number of aperiodic tracking reference signals. For example, network node 110 may transmit aperiodic tracking reference signals in a number less than or equal to the maximum number of aperiodic tracking reference signals.

In some aspects, sets 2 and 3 are not configured as quasi-co-located sources of downlink channels (such as the Physical Downlink Shared Channel (PDSCH) or the Physical Downlink Control Channel (PDCCH)). Therefore, only set 1 can be used as the TRS for downlink tracking. In some aspects, slot offsets for sets 2 and 3 may be defined for a cross-set delay (D) greater than or equal to two slots (e.g., D1 as described above). As shown in operation 615, UE 120 may transmit a slot offset indication associated with sets 2 and 3 based on a cross-set delay greater than or equal to two slots, and network node 110 may receive a slot offset indication associated with sets 2 and 3 based on a cross-set delay greater than or equal to two slots. In one example, transmitting a slot offset indication may include transmitting a report on the slot offset within a periodicity for a periodic tracking reference signal ( slotOffset The following instructions will be met: slotOffset#2(#3) – slotOffset#1 periodicity mod= D There are several time slots, where mod is a modulo function, #1 corresponds to set 1, #2 corresponds to set 2, and #3 corresponds to set 3. In another example, the transmit time slot offset indication may include an indication for a non-periodic tracking reference signal to be transmitted regarding the trigger time slot offset, which will satisfy the following: slotOffset#2(#3) – slotOffset#1 = D This ensures that the first tracking reference signal resource set (set 1) is buffered first without requiring any additional buffering for sets 2 and 3.

In the second example, UE 120 can multiply this parameter by a factor less than or equal to 20. d max The value is used to calculate the measurement window (e.g., based on the value). d value <= d max Export w = d N measP For example, for those reported as eight time slots... d max Based on the supported existing CSI-RS periodic values, d = {4,5,8}, and can N measP The report is {4,3,2} exported (separately). w = {16,15,16}.
