Description

Technical Field

[0001] This disclosure relates generally to communication systems, and more specifically to wireless communication utilizing overlay maps. Background Technology

[0002] Wireless communication systems are widely deployed to provide a variety of telecommunications services, such as telephone, video, data, messaging, and broadcasting. Typical wireless communication systems may 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 telecommunications standards to provide a common protocol that enables different wireless devices to communicate at the city, national, regional, and even global levels. An example telecommunications standard is 5G New Radio (NR). 5G NR is part of the Continuous Evolution of Mobile Broadband (CEM) program issued by the 3rd Generation Partnership Project (3GPP) to meet new requirements associated with latency, reliability, security, scalability (e.g., with the 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. Further improvements to 5G NR technology are needed. Furthermore, these improvements can also be applied to other multiple access technologies and telecommunications standards that adopt these technologies. Summary of the Invention

[0028] Wireless communication networks can be designed to support communication between network nodes (e.g., base stations, gNBs, etc.) and UEs. For example, network nodes and UEs in a wireless communication network can communicate in various configurations utilizing coverage maps. Coverage maps enable a variety of applications, such as UE positioning, route selection, remote driving, emergency transportation service / management, etc. Communication quality statistics for coverage maps can include uplink and downlink rates per user (which can be calculated, for example, by packet block size (TBS) and packet decoding error rate), packet delay, Received Signal Strength Indicator (RSSI) for each Tx-Rx antenna pair, etc.

[0029] Channel autocorrelation can also be an influential factor in wireless communications, such as channel prediction and mobile communications. Channel autocorrelation information can be environment-dependent and therefore related to, for example, the location of the UE. Additionally, for vehicle communications, adaptive rate transmission can be based on channel autocorrelation, as is the case in multiple-input multiple-output (MIMO) scenarios. If the channel autocorrelation is known, adaptive rate transmission can achieve data rates up to 10 times higher for multi-user MIMO (MU-MIMO) vehicle communications than without it, and such high data rates can be used in related applications such as video streaming. However, while channel autocorrelation information allows adaptive rate transmission to enhance the performance of vehicle communications in high-Doppler MIMO scenarios, the radio coverage map lacks enhancement from channel autocorrelation information.

[0030] Various aspects collectively involve wireless communication utilizing coverage maps. Some aspects more specifically involve channel autocorrelation within radio coverage maps. In one example, channel measurements for collecting autocorrelation information can be performed by network nodes (e.g., base stations, gNBs, etc.) and / or UEs / vehicles based on measurement pilots to generate a channel autocorrelation map that will be used for communication between network nodes and / or UEs / vehicles. In a further example, crowdsourced channel autocorrelation information can be obtained by network nodes from multiple UEs / vehicles. In some examples, channel autocorrelation information / values ​​from the channel autocorrelation map can be requested by the UE / vehicle, and the network node can provide / send a corresponding response message. In the example, for UE / vehicle communication, the collection of autocorrelation information in areas outside road boundaries can be excluded. In the example, the channel autocorrelation map can be stored locally near the network node or globally on servers at different geographical locations.

[0031] 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, the described techniques can be used to generate channel autocorrelation coverage maps that improve communication with high-Doppler UEs (e.g., increase data rates) by collecting channel autocorrelation information and adding such information to radio coverage maps.

[0032] The detailed descriptions following, illustrated with reference to the accompanying drawings, describe various configurations and do not represent the only configurations in which the concepts described herein can be practiced. To provide a thorough understanding of the various concepts, the detailed descriptions include specific details. However, these concepts can be practiced without these specific details. In some instances, well-known structures and components are shown in block diagram form to avoid obscuring these concepts.

[0033] Various apparatuses and methods are presented with reference to several aspects of a telecommunications system. These apparatuses and methods are described in detail below and illustrated in the accompanying drawings by various blocks, components, circuits, processes, algorithms, etc. (collectively, “elements”). These elements may be implemented using electronic hardware, computer software, or any combination thereof. Whether these elements are implemented as hardware or software depends on the specific application and the design constraints imposed on the system as a whole.

[0034] As an example, an element, any part of an element, or any combination of elements may be implemented as a "processing system" including one or more processors. When multiple processors are implemented, the multiple processors may perform functions individually or in combination. Examples of processors include microprocessors, microcontrollers, graphics processing units (GPUs), central processing units (CPUs), application processors, digital signal processors (DSPs), reduced instruction set computing (RISC) processors, system-on-a-chip (SoCs), baseband processors, field-programmable gate arrays (FPGAs), programmable logic devices (PLDs), state machines, gate logic, discrete hardware circuits, and other suitable hardware configured to perform the various functionalities described throughout this disclosure. One or more processors in a processing system may execute software. Whether referred to as software, firmware, middleware, microcode, hardware description language, or other terms, software should be broadly interpreted as instructions, instruction sets, code, code segments, program code, programs, subroutines, software components, applications, software applications, software packages, routines, subroutines, objects, executable files, threads of execution, procedures, functions, or any combination thereof.

[0035] Therefore, in one or more example aspects, specific implementations, and / or use cases, the described functionality may be implemented in hardware, software, or any combination thereof. If implemented in software, the functionality may be stored or encoded as one or more instructions or code on a computer-readable medium. Computer-readable media include computer storage media. Storage media can be any available medium that can be accessed by a computer. By way of example, such computer-readable media may include random access memory (RAM), read-only memory (ROM), electrically erasable programmable ROM (EEPROM), optical disc storage devices, magnetic disk storage devices, other magnetic storage devices, combinations of these 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 accessible by a computer.

[0036] While aspects, implementations, and / or use cases are described herein by way of example, additional or different aspects, implementations, and / or use cases may arise in many different arrangements and scenarios. The aspects, implementations, and / or use cases described herein can be implemented across many different platform types, devices, systems, shapes, sizes, and package arrangements. For example, aspects, implementations, and / or use cases may arise via integrated chip implementations and other devices based on non-modular components (e.g., end-user devices, vehicles, communication devices, computing devices, industrial equipment, retail / purchasing devices, medical devices, AI-enabled devices, etc.). While some examples may or may not be specific to a use case or application, the described examples may exhibit broad applicability. Aspects, implementations, and / or use cases can range from chip-level or modular components to non-modular, non-chip-level implementations, and further to aggregated, distributed, or original equipment manufacturer (OEM) devices or systems incorporating one or more of the technologies described herein. In some practical settings, devices incorporating the described aspects and features may also include additional components and features for implementing and practicing the claimed and described aspects. For example, the transmission and reception of wireless signals necessarily involve multiple components for analog and digital purposes (e.g., hardware components including antennas, RF chains, power amplifiers, modulators, buffers, processors, interleavers, adders / summers, etc.). The techniques described herein can be practiced in a wide variety of devices, chip-level components, systems, distributed arrangements, aggregated or decomposed components, end-user equipment, etc., of various sizes, shapes, and configurations.

[0037] The deployment of communication systems such as 5G NR systems can be arranged in a variety of ways using various components or parts. In a 5G NR system or network, network nodes, network entities, network mobility elements, radio access network (RAN) nodes, core network nodes, network elements or network equipment (such as base stations (BS)) or one or more units (or components) performing base station functions can be implemented in aggregated or decomposed architectures. For example, BSs (such as Node B (NB), evolved NB (eNB), NR BS, 5G NB, access point (AP), transmit / receive point (TRP), or cell, etc.) can be implemented as aggregated base stations (also known as standalone BS or monolithic BS) or decomposed base stations.

[0038] Aggregated base stations can be configured to utilize a radio protocol stack that is physically or logically integrated within a single RAN node. Decentralized base stations can be configured to utilize a protocol stack that is physically or logically distributed across 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 respects, the CU may be implemented within a RAN node, and one or more DUs may co-located with the CU, or alternatively, may be geographically or virtually distributed across one or more other RAN nodes. DUs may be implemented to communicate with one or more RUs. Each of the CU, DU, and RU may be implemented as a virtual unit, namely a virtual central unit (VCU), a virtual distributed unit (VDU), or a virtual radio unit (VRU).

[0039] Base station operation or network design can take into account the aggregation characteristics of base station functionality. For example, decomposed base stations can be utilized in Integrated Access Backhaul (IAB) networks, Open Radio Access Networks (O-RAN (such as network configurations initiated by the O-RAN Alliance)), or Virtualized Radio Access Networks (vRAN, also known as Cloud Radio Access Networks (C-RAN)). Decomposition can include distributing functionality across two or more units in various physical locations, as well as virtually distributing the functionality of at least one unit, which enables flexibility in network design. The various units of a decomposed base station or decomposed RAN architecture can be configured to communicate wirelessly with at least one other unit.

[0040] Figure 1 Figure 100 illustrates an example of a wireless communication system and access network. The illustrated wireless communication system includes a decomposed base station architecture. The decomposed base station architecture may include one or more CUs 110, which may communicate directly with the core network 120 via a backhaul link, or indirectly with the core network 120 via one or more decomposed 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. CUs 110 may communicate with one or more DUs 130 via a corresponding midhaul link (such as an F1 interface). DUs 130 may communicate with one or more RUs 140 via a corresponding fronthaul link. RUs 140 may communicate with a corresponding UE 104 via one or more radio frequency (RF) access links. In some implementations, a UE 104 may be served simultaneously by multiple RUs 140.

[0041] Each of the units (i.e., CU 110, DU 130, RU 140, and near-RT RIC 125, non-RT RIC 115, and SMO frame 105) may include or be coupled to one or more interfaces configured to receive or transmit signals, data, or information (collectively, signals) via wired or wireless transmission media. Each of the units, or an associated processor or controller providing instructions to the communication interfaces of these units, may be configured to communicate with one or more other units via transmission media. For example, these units may include wired interfaces configured to receive signals via wired transmission media or transmit signals to one or more other units. Additionally, these units may include wireless interfaces that may include receivers, transmitters, or transceivers (such as RF transceivers) configured to receive signals via wireless transmission media or transmit signals to one or more other units, or both.

[0042] In some aspects, the CU 110 can host one or more higher-level control functions. Such control functions may include Radio Resource Control (RRC), Packet Data Convergence Protocol (PDCP), Serving Data Adaptation Protocol (SDAP), etc. Each control function can be implemented using an interface configured to signal to 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 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 110 can be implemented to communicate with the DU 130 for network control and signaling, as needed.

[0043] DU 130 may correspond to a logic unit that includes one or more base station functions for controlling the operation of one or more RU 140s. In some aspects, DU 130 may at least partially host one or more of the Radio Link Control (RLC) layer, Media 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, demodulation, etc.) according to functional splits (such as those defined by 3GPP). In some aspects, DU 130 may also host one or more low PHY layers. Each layer (or module) may be implemented using an interface configured to communicate signals with other layers (and modules) hosted by DU 130 or with control functions hosted by CU 110.

[0044] Lower-layer functionality can be implemented by one or more RU 140s. In some deployments, an RU140 controlled by a DU 130 may correspond to a logical node that hosts 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, or both, based at least in part on functional decomposition (such as lower-layer functional decomposition). In such architectures, the RU 140 may be implemented to handle over-the-air (OTA) communications with one or more UE 104s. In some specific implementations, the real-time and non-real-time aspects of communication with the control plane and user plane of the RU 140 may be controlled by the corresponding DU 130. In some scenarios, this configuration enables the implementation of the DU 130 and CU 110 in a cloud-based RAN architecture (such as a vRAN architecture).

[0045] SMO framework 105 can be configured to support RAN deployment and provisioning of both non-virtualized and virtualized network elements. For non-virtualized network elements, SMO framework 105 can be configured to support 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, 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 instantiating virtualized network elements) via a cloud computing platform interface such as the O2 interface. Such virtualized network elements may include, but are not limited to, CU 110, DU 130, RU 140, and near-RT RIC 125. In some implementations, SMO framework 105 can communicate with the hardware aspects of the 4G RAN (such as Open eNB (O-eNB) 111) via the O1 interface. Additionally, in some implementations, SMO framework 105 can communicate directly with one or more RU 140s via the O1 interface. SMO framework 105 may also include a non-RT RIC 115 configured to support the functionality of SMO framework 105.

[0046] The non-RT RIC 115 can be configured to include logical functions enabling non-real-time control and optimization of RAN elements and resources, including artificial intelligence (AI) / machine learning (ML) workflows for model training and updates, or policy-based guidance for applications / features in the near-RT RIC 125. The non-RT RIC 115 can be coupled to or communicate with the near-RT RIC 125 (e.g., via an A1 interface). The near-RT RIC 125 can be configured to include logical functions enabling near real-time control and optimization of RAN elements and resources via data collection and actions through an interface (e.g., via an E2 interface) that connects one or more CU 110s, one or more DU 130s, or both, and O-eNBs to the near-RT RIC 125.

[0047] In some implementations, to generate AI / ML models to be deployed in the near-RT RIC 125, the non-RT RIC 115 may receive parameters or external enrichment information from an external server. This information can be utilized by the near-RT RIC 125 and can be received from non-network data sources or network functions at the SMO framework 105 or the non-RT RIC 115. In some examples, the non-RT RIC 115 or the near-RT RIC 125 may be configured to tune RAN behavior or performance. For example, the non-RT RIC 115 may monitor long-term trends and patterns in performance and use AI / ML models to perform corrective actions via the SMO framework 105 (such as reconfiguration via O1) or by creating RAN management policies (such as A1 policies).

[0048] At least one of CU 110, DU 130, and RU 140 may be referred to as base station 102. Therefore, base station 102 may include one or more of CU 110, DU 130, and RU 140 (each component is indicated by a dashed line to indicate that each component may or may not be included in base station 102). Base station 102 provides UE 104 with an access point to core network 120. Base station 102 may include macro cells (high-power cellular base stations) and / or small cells (low-power cellular base stations). Small cells include femtocells, picocells, and microcells. A network that includes both small cells and macro cells may be referred to as a heterogeneous network. A heterogeneous network may also include an evolved home node B (eNB) (HeNB), which can provide service to a restricted group referred to as a closed subscriber group (CSG). The communication link between RU140 and UE 104 may include uplink (UL) transmission (also known as reverse link) from UE 104 to RU 140 and / or downlink (DL) transmission (also known as forward link) transmission from RU 140 to UE 104. The communication link may utilize multiple-input multiple-output (MIMO) antenna techniques, including spatial multiplexing, beamforming, and / or transmit diversity. The communication link may use one or more carriers. For each direction, the total number of carriers used for transmission can be up to [number missing]. Yx MHz ( x For each carrier allocated in carrier aggregation (of component carriers), base station 102 / UE 104 can use up to [number] carriers. Y A spectrum with a bandwidth of MHz (e.g., 5MHz, 10MHz, 15MHz, 20MHz, 100MHz, 400MHz, etc.). Carriers may be adjacent to each other or may not be adjacent to each other. Carrier allocation may be asymmetric with respect to DL and UL (e.g., more or fewer carriers may be allocated to DL compared to UL). Component carriers may include primary component carriers and one or more secondary component carriers. The primary component carrier may be referred to as the primary cell (PCell) and the secondary component carrier may be referred to as the secondary cell (SCell).

[0049] Some UEs 104 can communicate with each other using device-to-device (D2D) communication link 158. D2D communication link 158 can use DL / UL wireless wide area network (WWAN) spectrum. D2D communication link 158 can use one or more sidelink channels, such as Physical Sidelink Broadcast Channel (PSBCH), Physical Sidelink Discovery Channel (PSDCH), Physical Sidelink Shared Channel (PSSCH), and Physical Sidelink Control Channel (PSCCH). D2D communication can be performed through various wireless D2D communication systems, such as Bluetooth. ™ (Bluetooth is a trademark of the Bluetooth Special Interest Group (SIG), and is based on the IEEE 802.11 standard for Wi-Fi.) ™(Wi-Fi is a trademark of the Wi-Fi Alliance), LTE, or NR.

[0050] The wireless communication system may also include a Wi-Fi AP 150, which communicates with the UE 104 (also referred to as a Wi-Fi station (STA)) via a communication link 154, for example, in an unlicensed spectrum such as 5 GHz. When communicating in unlicensed spectrum, the UE 104 / AP 150 may perform a free channel assessment (CCA) to determine whether the channel is available before communication.

[0051] The electromagnetic spectrum is typically subdivided into various categories, bands, channels, etc., based on frequency / wavelength. In 5G NR, two initial operating bands have been designated as frequency ranges FR1 (410MHz to 7.125GHz) and FR2 (24.25GHz to 52.6GHz). Although a portion of FR1 is greater than 6GHz, FR1 is generally (interchangeably) referred to as the "sub-6GHz" band in various documents and articles. Similar naming issues sometimes occur with FR2, which is generally (interchangeably) referred to as the "millimeter wave" band in documents and articles, although this is distinct from the Extremely High Frequency (EHF) band (30GHz to 300GHz) designated as "millimeter wave" by the International Telecommunication Union (ITU).

[0052] The frequencies between FR1 and FR2 are generally referred to as mid-band frequencies. Recent 5G NR studies have identified the operating bands used for these mid-band frequencies as the frequency range designation FR3 (7.125 GHz to 24.25 GHz). Bands falling within FR3 can inherit FR1 and / or FR2 characteristics, thus effectively extending the features of FR1 and / or FR2 to mid-band frequencies. Furthermore, higher frequency bands are currently being explored to extend 5G NR operation beyond 52.6 GHz. For example, three higher operating bands have been identified as the 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 frequency bands falls within the EHF band.

[0053] In view of the above, unless otherwise specifically stated, the term "below 6 GHz" as used herein can broadly refer to frequencies less than 6 GHz, within FR1, or including intermediate frequency band frequencies. Furthermore, unless otherwise specifically stated, the term "millimeter wave" as used herein can broadly refer to frequencies that can include intermediate frequency band frequencies, within FR2, FR4, FR2-2 and / or FR5, or within the EHF band.

[0054] Base station 102 and UE 104 may each include multiple antennas (such as antenna elements, antenna panels, and / or antenna arrays) to facilitate beamforming. Base station 102 may transmit beamformed signals 182 to UE 104 in one or more transmit directions. UE 104 may receive beamformed signals from base station 102 in one or more receive directions. UE 104 may also transmit beamformed signals 184 to base station 102 in one or more transmit directions. Base station 102 may receive beamformed signals from UE 104 in one or more receive directions. Base station 102 / UE 104 may perform beamforming training to determine the optimal receive and transmit directions for each of base station 102 / UE 104. The transmit and receive directions of base station 102 may be the same or different. The transmit and receive directions of UE 104 may be the same or different.

[0055] Base station 102 may include and / or be referred to as gNB, Node B, eNB, access point, base transceiver, radio base station, radio transceiver, transceiver function, basic service set (BSS), extended service set (ESS), TRP, network node, network entity, network equipment, or some other suitable terminology. Base station 102 may be implemented as an integrated access and backhaul (IAB) node, relay node, sidelink node, aggregated (monolithic) base station with baseband units (BBU) (including CU and DU) and RU, or may be implemented as a decomposed base station including one or more of CU, DU, and / or RU. A collection of base stations that may include decomposed base stations and / or aggregated base stations may be referred to as Next Generation (NG) RAN (NG-RAN).

[0056] The core network 120 may include Access and Mobility Management Function (AMF) 161, Session Management Function (SMF) 162, User Plane Function (UPF) 163, Unified Data Management (UDM) 164, one or more location servers 168, and other functional entities. AMF 161 is the control node that processes signaling between UE 104 and the core network 120. AMF 161 supports registration management, connection management, mobility management, and other functions. SMF 162 supports session management and other functions. UPF 163 supports packet routing, packet forwarding, and other functions. UDM 164 supports authentication and key agreement (AKA) credential generation, user identity processing, access authorization, and subscription management. One or more location servers 168 are exemplified as including a Gateway Mobile Location Center (GMLC) 165 and a Location Management Function (LMF) 166. However, generally, one or more location servers 168 may include one or more location / positioning servers, which may include one or more of GMLC 165, LMF 166, Position Determination Entity (PDE), Serving Mobile Location Center (SMLC), Mobile Location Center (MPC), etc. GMLC 165 and LMF 166 support UE location services. GMLC 165 provides an interface for clients / applications (e.g., emergency services) to access UE location information. LMF 166 receives measurement and auxiliary information from NG-RAN and UE 104 via AMF 161 to calculate the location of UE 104. NG-RAN may use one or more positioning methods to determine the location of UE 104. Positioning UE 104 may involve signal measurement, location estimation, and optional speed calculation based on these measurements. Signal measurement may be performed by UE 104 and / or base station 102 serving UE 104. The measured signals may be based on one or more of the following: Satellite Positioning System (SPS) 170 (e.g., one or more of Global Navigation Satellite System (GNSS), Global Positioning System (GPS), Non-Terrestrial Network (NTN) or other satellite positioning / location systems), LTE signals, Wireless Local Area Network (WLAN) signals, Bluetooth signals, Terrestrial Beacon System (TBS), sensor-based information (e.g., barometric pressure sensor, motion sensor), NR Enhanced Cell ID (NR E-CID) method, NR signals (e.g., multiple round-trip time (multiple RTT), DL departure angle (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.

[0057] Examples of UE 104 include cellular phones, smartphones, Session Initiation Protocol (SIP) phones, laptops, personal digital assistants (PDAs), satellite radios, GPS devices, multimedia devices, video devices, digital audio players (e.g., MP3 players), cameras, game consoles, tablets, smart devices, wearable devices, vehicles, electricity meters, air pumps, large or small kitchen appliances, healthcare devices, implants, sensors / actuators, displays, or any other similarly functional device. Some UEs in UE 104 may be referred to as IoT devices (e.g., parking timers, air pumps, toasters, vehicles, heart monitors, etc.). UE 104 may also be referred to as a station, mobile station, subscriber station, mobile unit, subscriber unit, wireless unit, remote unit, mobile device, wireless device, wireless communication device, remote device, mobile subscriber station, access terminal, mobile terminal, wireless terminal, remote terminal, mobile phone, user agent, mobile client, client, or some other suitable terminology. In some scenarios, the term UE may also be applied to one or more companion devices, such as in a device constellation arrangement. One or more of these devices may access the network together and / or individually.

[0058] Refer again Figure 1In some aspects, UE 104 may have component 198, which can be configured to provide a network node with at least one channel autocorrelation measurement pilot indicating channel information of a communication channel and location information associated with the UE, based on a configuration associated with the periodic transmission of at least one channel autocorrelation measurement pilot.

Component 198 may be configured to receive at least one channel autocorrelation value of the channel autocorrelation map from the network node, wherein the channel autocorrelation map is based on at least one channel autocorrelation measurement pilot indicating the channel information of the communication channel and the location information associated with the UE. Component 198 may be configured to receive a broadcast autocorrelation measurement pilot from a network node, wherein the header of the broadcast autocorrelation measurement pilot includes an index indicating the performance of at least one channel autocorrelation measurement. Component 198 may be configured to perform at least one channel autocorrelation measurement based on the broadcast autocorrelation measurement pilot and a measurement configuration. Component 198 may be configured to provide the network node with at least one channel autocorrelation measurement and an indication of location information associated with the UE. Component 198 may be configured to provide the network node with a request message indicating the UE's request for at least one channel autocorrelation value from a channel autocorrelation map. Component 198 may be configured to receive, from the network node and based on the request message, a request response message indicating at least one channel autocorrelation value of the channel autocorrelation map. In some aspects, base station 102 may have component 199, which may be configured to configure the UE with a configuration periodically associated with the transmission of at least one channel autocorrelation measurement pilot. Component 199 may also be configured to receive, from the UE and based on the configuration, at least one channel autocorrelation measurement pilot indicating channel information of a communication channel and location information associated with the UE. Component 199 may also be configured to communicate with the UE based on a channel autocorrelation map associated with at least one channel autocorrelation measurement pilot indicating a communication channel and location information associated with the UE.

Component 199 may be configured to provide the UE with a broadcast autocorrelation measurement pilot, wherein the header of the broadcast autocorrelation measurement pilot includes an index indicating the performance of at least one channel autocorrelation measurement.Component 199 can be configured to receive from the UE at least one channel autocorrelation measurement based on a broadcast autocorrelation measurement pilot and an indication of location information associated with the UE. Component 199 can be configured to receive from the UE a request message indicating a request for at least one channel autocorrelation value of the channel autocorrelation map. Component 199 can be configured to provide a request response message indicating the at least one channel autocorrelation value to the UE and based on the request message. Therefore, the aspects of channel autocorrelation in radio coverage maps described herein enable channel measurements for collecting autocorrelation information to be performed by network nodes and / or UEs (e.g., in and / or including vehicles or other means of transport) based on measurement pilots to generate channel autocorrelation maps that will be used in communications between network nodes and / or UEs. The described aspects provide for generating channel autocorrelation coverage maps by collecting channel autocorrelation information (such as from individual UEs or via crowdsourcing of multiple UEs) and adding such information to radio coverage maps, which improve communication with high-Doppler UEs, for example, by increasing data rates.

[0059] Figure 2A Figure 200 illustrates an example of the first subframe within a 5G NR frame structure. Figure 2B Figure 230 illustrates an example of a DL channel within a 5G NR subframe. Figure 2C Figure 250 is an example of a second subframe within a 5G NR frame structure. Figure 2D Figure 280 illustrates an example of a UL channel within a 5G NR subframe. The 5G NR frame structure can be Frequency Division Duplex (FDD) (where subframes within a specific set of subcarriers (carrier system bandwidth) are dedicated to either DL or UL) or Time Division Duplex (TDD) (where subframes within a specific set of subcarriers (carrier system bandwidth) are dedicated to both DL and UL). Figure 2A , Figure 2CIn the provided example, the 5G NR frame structure is assumed to be TDD, where subframe 4 is configured with slot format 28 (most of which are DL), where D is DL, U is UL, and F is flexible and can be used between DL / UL, and subframe 3 is configured with slot format 1 (all of which are UL). Although subframes 3 and 4 are shown as having slot formats 1 and 28 respectively, any particular subframe can be configured with any of the various available slot formats 0 to 61. Slot formats 0 and 1 are both DL and UL, respectively. Other slot formats 2 to 61 include a mixture of DL, UL, and flexible symbols. The slot format is configured for the UE via the received Slot Format Indicator (SFI) (dynamically configured via DL Control Information (DCI) or semi-statically / statically configured via Radio Resource Control (RRC) signaling). Note that the following description also applies to the 5G NR frame structure as TDD.

[0060] Figures 2A to 2D The frame structure is illustrated, and aspects of this disclosure are applicable to other wireless communication technologies that may have different frame structures and / or different channels. A frame (10 ms) can be divided into 10 equal-sized subframes (1 ms). Each subframe may include one or more time slots. Subframes may also include micro-time slots, which may include 7, 4, or 2 symbols. Each time slot may include 14 or 12 symbols, depending on whether the cyclic prefix (CP) is normal or extended. For normal CP, each time slot may include 14 symbols, and for extended CP, each time slot may include 12 symbols. Symbols on the DL may be CP Orthogonal Frequency Division Multiplexing (OFDM) (CP-OFDM) symbols. Symbols on the UL may be CP-OFDM symbols (for high-throughput scenarios) or Discrete Fourier Transform (DFT) Extended OFDM (DFT-s-OFDM) symbols (for power-constrained scenarios; limited to single-stream transmission). The number of time slots within a subframe is based on the CP and a parameter set. The parameter set defines the subcarrier spacing (SCS) (see Table 1). The symbol length / duration can be scaled by 1 / SCS. Table 1: Parameter Set, SCS, and CP

[0061] For a normal CP (14 symbols / slot), different parameter sets µ 0 through 4 allow 1, 2, 4, 8, and 16 slots per subframe, respectively. For the extended CP, parameter set 2 allows 4 slots per subframe. Therefore, for a normal CP and parameter set µ, there are 14 symbols per slot and 2 slots per subframe. µ One time slot. The subcarrier spacing can be equal to ,in The parameter sets are 0 to 4. Therefore, the subcarrier spacing is 15 kHz for parameter set µ=0 and 240 kHz for parameter set µ=4. The symbol length / duration is negatively correlated with the subcarrier spacing. Figures 2A to 2D Examples of a normal frequency division multiplexing (CP) with 14 symbols per time slot and a parameter set of µ=2 with 4 time slots per subframe are provided. The time slot duration is 0.25 ms, the subcarrier spacing is 60 kHz, and the symbol duration is approximately 16.67 μs. Within the frame set, there may be one or more distinct bandwidth portions (BWPs) of frequency division multiplexing (see [link to relevant documentation]). Figure 2B Each BWP can have a specific set of parameters and CP (normal or extended).

[0062] A resource grid can be used to represent the frame structure. Each time slot consists of a resource block (RB) extending for 12 consecutive subcarriers (also known as a physical RB (PRB)). The resource grid is divided into multiple resource elements (REs). The number of bits carried by each RE depends on the modulation scheme.

[0063] like Figure 2A As illustrated, some of the REs carry reference (pilot) signals (RS) for the UE. RS may include demodulation RS (DM-RS) (indicated as R for a particular configuration, but other DM-RS configurations are possible) and channel state information reference signals (CSI-RS) for channel estimation at the UE. RS may also include beam measurement RS (BRS), beam refinement RS (BRRS), and phase tracking RS (PT-RS).

[0064] Figure 2BExamples of various DL channels within a subframe of a frame are illustrated. The Physical Downlink Control Channel (PDCCH) carries the DCI within one or more Control Channel Elements (CCEs) (e.g., 1, 2, 4, 8, or 16 CCEs), each CCE comprising six RE Groups (REGs), each REG comprising 12 consecutive REs in the OFDM symbol of the RB. A PDCCH within a BWP can be referred to as a Control Resource Set (CORESET). The UE is configured to monitor PDCCH candidates in the PDCCH search space (e.g., the common search space, the UE-specific search space) during PDCCH monitoring timing on the CORESET, where the PDCCH candidates have different DCI formats and different aggregation levels. Additional BWPs may be located at higher and / or lower frequencies on the channel bandwidth. The Primary Synchronization Signal (PSS) may be located within symbol 2 of a specific subframe of the frame. The PSS is used by the UE 104 to determine subframe / symbol timing and physical layer identification. The Secondary Synchronization Signal (SSS) may be located within symbol 4 of a specific subframe of the frame. The SSS is used by the UE to determine the Physical Layer Cell Identifier Group Number and radio frame timing. Based on the Physical Layer Identifier and the Physical Layer Cell Identifier Group Number, the UE can determine the Physical Cell Identifier (PCI). Based on the PCI, the UE can determine the location of the DM-RS. The Physical Broadcast Channel (PBCH), carrying the Master Information Block (MIB), can be logically grouped with the PSS and SSS to form a Synchronization Signal (SS) / PBCH block (also known as an SS block (SSB)). The MIB provides the System Frame Number (SFN) and the number of Restricted Frames (RBs) in the system bandwidth. The Physical Downlink Shared Channel (PDSCH) carries user data, broadcast system information not transmitted via the PBCH (such as System Information Blocks (SIBs)), and paging messages.

[0065] like Figure 2C As illustrated, some REs in the REs carry DM-RS (indicated as 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 or first two symbols of the PUSCH. Depending on whether a short or long PUCCH is transmitted and depending on the specific PUCCH format used, the PUCCH DM-RS can be transmitted in different configurations. The UE can transmit a Sounding Reference Signal (SRS). The SRS can be transmitted in the last symbol of a subframe. The SRS can have a comb structure, and the UE can transmit the SRS on one of the comb teeth. The SRS can be used by the base station for channel quality estimation to enable frequency-dependent scheduling of the UL.

[0066] Figure 2DExamples of various UL channels within a subframe of a frame are illustrated. The PUCCH may be located as indicated in one configuration. The PUCCH carries uplink control information (UCI), such as scheduling requests, channel quality indicators (CQI), pre-decoding matrix indicators (PMI), rank indicators (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 PUCCH carries data and may additionally be used to carry buffer status reports (BSR), power clearance reports (PHR), and / or UCIs.

[0067] Figure 3 This is a block diagram illustrating communication between base station 310 and UE 350 in the access network. In the DL, Internet Protocol (IP) packets can be provided to controller / processor 375. Controller / processor 375 implements Layer 3 and Layer 2 functionality. Layer 3 includes the Radio Resource Control (RRC) layer, and Layer 2 includes the Service Data Adaptation Protocol (SDAP) layer, Packet Data Convergence Protocol (PDCP) layer, Radio Link Control (RLC) layer, and Media Access Control (MAC) layer. The controller / processor 375 provides RRC layer functionality associated with broadcasting system information (e.g., MIB, SIB), 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 for UE measurement reporting; PDCP layer functionality associated with header compression / decompression, security (encryption, decryption, integrity protection, integrity verification), and handover support functions; RLC layer functionality associated with the delivery of upper-layer packet data units (PDUs), error correction via ARQ, concatenation, segmentation, and reassembly of RLC service data units (SDUs), resegmentation 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 transport blocks (TBs), demultiplexing of MAC SDUs from TBs, scheduling information reporting, error correction via HARQ, priority handling, and logical channel priority ordering.

[0068] 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 is spatially pre-decoded to generate multiple spatial streams. A channel estimate from channel estimator 374 is used to determine the decoding and modulation scheme, as well as for spatial processing. This channel estimate can be derived from a reference signal transmitted by UE 350 and / or channel condition feedback. Each spatial stream can then be provided to a different antenna 320 via a separate transmitter 318Tx. Each transmitter 318Tx can use the corresponding spatial stream to modulate a radio frequency (RF) carrier for transmission.

[0069] 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 channel estimates calculated by channel estimator 358. Subsequently, the soft decision is 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.

[0070] The controller / processor 359 may be associated with at least one memory 360 storing program code and data. The at least one memory 360 may be referred to as a computer-readable medium. In the UL, the controller / processor 359 provides demultiplexing, packet reassembly, decryption, header decompression, and control signal processing between transport and logical channels to recover IP packets. The controller / processor 359 is also responsible for error detection using ACK and / or NACK protocols to support HARQ operation.

[0071] Similar to the functionality described in conjunction with DL transmission performed by base station 310, controller / processor 359 provides RRC layer functionality associated with system information (e.g., MIB, SIB) acquisition, RRC connectivity, and measurement reporting; PDCP layer functionality associated with header compression / decompression and security (encryption, decryption, integrity protection, integrity verification); RLC layer functionality associated with upper-layer PDU delivery, error correction via ARQ, concatenation, segmentation, and reassembly of RLC SDUs, resegmentation 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 via HARQ, priority handling, and logical channel priority ordering.

[0072] The TX processor 368 can use the channel estimate derived from the reference signal or feedback transmitted by the channel estimator 358 from the base station 310 to select an appropriate decoding and modulation scheme and facilitate spatial processing. The spatial stream generated by the TX processor 368 can be provided to different antennas 352 via individual transmitters 354Tx. Each transmitter 354Tx can use the corresponding spatial stream to modulate an RF carrier for transmission.

[0073] UL transmission is processed at base station 310 in a manner similar to that described in conjunction with the receiver function at UE 350. Each receiver 318Rx receives signals via its corresponding antenna 320. Each receiver 318Rx recovers the information modulated onto the RF carrier and provides that information to RX processor 370.

[0074] The controller / processor 375 may be associated with at least one memory 376 storing program code and data. The at least one memory 376 may be referred to as a computer-readable medium. In the UL, the controller / processor 375 provides demultiplexing, packet reassembly, decryption, header decompression, and control signal processing to recover IP packets between transport and logical channels. The controller / processor 375 is also responsible for error detection using ACK and / or NACK protocols to support HARQ operation.

[0075] At least one of the TX processor 368, RX processor 356, and controller / processor 359 can be configured to perform coupling. Figure 1 The components of 198 are all aspects.

[0076] At least one of the TX processor 316, RX processor 370, and controller / processor 375 can be configured to perform coupling. Figure 1 The components of 199 in all aspects.

[0077] As described above, network nodes and UEs in a wireless communication network can communicate in various configurations utilizing coverage maps, enabling a wide range of applications such as UE positioning, route selection, remote driving, and emergency vehicle service / management. Channel autocorrelation can also affect wireless communication between network nodes and UEs (such as channel prediction and mobile communication) and can be environment-dependent and / or location-dependent. For vehicle communication, adaptive rate transmission can be based on channel autocorrelation, as is the case for multiple-input multiple-output (MIMO). If the channel autocorrelation is known, using adaptive rate transmission can achieve data rates up to 10 times higher for multi-user MIMO (MU-MIMO) vehicle communication than without adaptive rate transmission, and such high data rates can be used for related applications such as video streaming.

[0078] Figure 4 Figure 400 is an example of a communication network utilizing a radio coverage map or channel autocorrelation. Figure 400 is described below in two contexts: a UE 402 communicating with each other and a network node (e.g., base station 404).

[0079] In one scenario, during communication 410 with base station 404, UE 402 may be in motion based on rate 406. UE 402 may be in a vehicle or other type of transport, or may include a vehicle or other type of transport. Communication 410 may include mobile applications (e.g., UE 402 positioning with or without base station 404), such as route selection for trips in a vehicle, remote driving of the vehicle associated with UE 402, emergency transportation service / management associated with UE 402, etc. Base station 404 may obtain (e.g., calculate and / or be provided) a radio coverage map 408 for the area in which UE 402 is present. Therefore, communication 410 may improve communication quality statistics that may be associated with the coverage map, such as uplink and downlink rates per user (which may be calculated, for example, by packet TBS and packet decoding error rate), packet delay, RSSI for each Tx-Rx antenna pair, etc.

[0080] In another scenario, during communication 414 with base station 404, UE 402 may be in motion based on rate 406'. UE 402 may be in a vehicle or other type of transportation, or may include a vehicle or other type of transportation, and may experience a high-Doppler MIMO scenario (e.g., at least partially based on rate 406'). Communication 414 may include channel prediction and mobile communication, and may depend on the environment and / or be location-dependent for UE 402. For vehicle communication associated with UE 402, adaptive rate transmission for communication 414 may be based on channel autocorrelation associated with channel autocorrelation information 412, for example, for MIMO scenarios. If the channel autocorrelation using channel autocorrelation information 412 is known, using adaptive rate transmission for communication 414 can achieve data rates up to 10 times higher for MU-MIMO vehicle communication than without adaptive rate transmission, and such high data rates can be used for related applications such as video streaming.

[0081] However, while channel autocorrelation can allow adaptive rate transmission to enhance vehicle communication performance in high Doppler MIMO scenarios, radio coverage maps lack the enhancement provided by channel autocorrelation. This paper provides methods whereby a vehicle UE is instructed to transmit location-based pilot signals to the network, enabling the network to create a channel autocorrelation map over the cell's coverage area. Once the map is generated, it can be provided to the UE, allowing the UE to optimize adaptive rate transmission. Using such a map, the UE can know its location, but may not need to share its location with the network (e.g., mitigating privacy concerns). This paper also describes some key aspects for data acquisition to create the map, including but not limited to: 1) UE configuration for periodic pilot transmission (e.g., time intervals, temporal / spatial periodicity, etc.); and 2) additional UE information to be transmitted, such as location information, e.g., "area" identifier (ID), GNSS location, vehicle model, etc.

[0082] This document provides aspects of channel autocorrelation in radio coverage maps. In one example, channel measurements for collecting autocorrelation information can be performed by network nodes (e.g., base stations, gNBs, etc.) and / or UEs / vehicles based on measurement pilots to generate a channel autocorrelation map that will be used for communication between network nodes and / or UEs / vehicles. In a further example, crowdsourced channel autocorrelation information can be obtained by network nodes from multiple UEs / vehicles. In some examples, channel autocorrelation information / values ​​from the channel autocorrelation map can be requested by the UE / vehicle, and the network node can provide / send a corresponding response message. In the example, for UE / vehicle communication, the collection of autocorrelation information in areas outside road boundaries can be excluded. In the example, the channel autocorrelation map can be stored locally near the network node or globally on servers at different geographical locations. The aspects provide methods for generating channel autocorrelation coverage maps by collecting channel autocorrelation information and adding such information to radio coverage maps, which improve communication with high-Doppler UEs, for example, by increasing data rates.

[0083] Figure 5 Call flowchart 500 illustrates various aspects of wireless communication. Call flowchart 500 shows channel autocorrelation in a radio coverage diagram of a wireless device (e.g., UE 502) communicating with a network node (e.g., base station 504, such as a gNB or other type of base station, as shown). The aspects described for base station 504 can be performed by the base station in an aggregated form and / or by one or more components of the base station in a decomposed form. Additionally or alternatively, these aspects can be performed autonomously by UE 502 as a supplement to and / or alternative to the operation of base station 504.

[0084] In the illustrated aspects, UE 502 may be configured to receive and base station 504 may be configured to transmit / provide configuration 506. Configuration 506 may be received by UE 502 and transmitted / provided by base station 504 before providing channel autocorrelation measurement pilots from UE 502 to base station 504. In various aspects, configuration 506 may be associated with the periodicity of transmission for the channel autocorrelation measurement pilots, and this configuration may indicate activation for enabling UE 502 to provide the channel autocorrelation measurement pilots to base station 504. In various aspects, configuration 506 may indicate that the periodicity of transmission for the channel autocorrelation measurement pilots is based on a time period length or the period of one or more time slots, and the channel autocorrelation measurement pilots may include at least one demodulation reference signal (DMRS) symbol for UE 502 or at least one symbol having a longer length than the DMRS symbol for UE 502. In various aspects, configuration 506 may indicate that the channel autocorrelation measurement pilots include multiple time slots, and the channel autocorrelation measurement pilots may include multiple time slots. In various aspects, configuration 506 may indicate the periodicity of channel autocorrelation measurement pilot transmission based on the distance interval traversed by UE 502. The distance interval traversed by UE 502 may be based on a measurement performed by UE 502 on that distance interval, and UE 502 may be configured to provide channel autocorrelation measurement pilots while also providing the velocity experienced by UE 502. In various aspects, UE 502 may be configured to receive and base station 504 may be configured to transmit / provide configuration 506 associated with the periodicity of channel autocorrelation measurement pilot transmission based on at least one of the following: (i) channel autocorrelation map update indication, (ii) establishment of a connection by UE 502 with a network node (e.g., base station 504), or (iii) location information associated with UE 502 associated with a road area selected for a road.

[0085] UE 502 can be configured to identify (at 508) channel information of a communication channel and location information associated with UE 502 based on configuration 506. In various aspects, the channel information of the communication channel can be identified (at 508) by performing channel measurements on the communication channel between UE 502 and base station 504. Based on such channel measurements, channel characteristics can be identified (at 508) as channel information (e.g., quality statistics, energy, power, SNR / SINR, etc.). In various aspects, the location information associated with UE 502 can be identified (at 508) as being further associated with at least a portion of a region of the channel autocorrelation map, and the location information associated with UE 502 may include a zone identifier, GNSS location, road segment identifier, road lane identifier, vehicle information associated with UE 502 (e.g., brand, model, year, etc.), or a set of transmission parameters of UE 502 (e.g., RF chain). In various aspects, the location information associated with UE 502 may exclude additional location information corresponding to at least one region outside the road boundary. In other words, this paper may utilize location information associated with the UE, such as information within the road boundaries, for aspects such as vehicle communication.

[0086] UE 502 can be configured to transmit / provide via a corresponding channel autocorrelation measurement pilot transmission, and base station 504 can be configured to receive at least one channel autocorrelation measurement pilot 510 (e.g., a channel autocorrelation measurement pilot). At least one channel autocorrelation measurement pilot 510 can be periodically transmitted / provided by UE 502 based on configuration 506, and correspondingly received by base station 504. For example, as described above, at least one channel autocorrelation measurement pilot 510 can be transmitted / provided via a channel autocorrelation measurement pilot transmission having a periodicity of multiple time slots with a time period length and / or number of time slots, having a periodicity associated with the distance traversed by UE 502 (e.g., the distance interval traversed by UE 502), and in such a configuration, at least one channel autocorrelation measurement pilot 510 may include or be accompanied by a velocity experienced by UE 502, etc. In all respects, at least one channel autocorrelation measurement pilot 510 may be transmitted / provided as a DMRS symbol for UE 502 or as a symbol having a longer length than the DMRS symbol for UE 502.

[0087] Base station 504 may be configured to generate a channel autocorrelation map by performing at least one channel autocorrelation measurement using at least one antenna pair of base station 504. In various respects, the execution of at least one channel autocorrelation measurement may be based on at least one channel autocorrelation measurement pilot 510. UE 502 may be configured to receive, and base station 504 may be configured to transmit / provide, at least one channel autocorrelation value of the channel autocorrelation map, wherein the channel autocorrelation map may be based on at least one channel autocorrelation measurement pilot 510 indicating (at 508) channel information of the identified communication channel and location information associated with UE 502.

[0088] UE 502 and base station 504 can be configured to communicate based on a channel autocorrelation map associated with at least one channel autocorrelation measurement pilot 510 that indicates the communication channel and location information associated with UE 502, for example, as communication 512. Communication 512 between UE 502 and base station 504 can be associated with the channel autocorrelation map and at least one channel autocorrelation measurement pilot 510. In various aspects, communication 512 between UE 502 and base station 504 can be based on the values ​​of the channel autocorrelation map transmitted / provided by base station 504 and received by UE 502.

[0089] Therefore, the aspects of channel autocorrelation in radio coverage maps described in this paper enable the generation of channel autocorrelation coverage maps by collecting channel autocorrelation information and adding such information to the radio coverage map. These channel autocorrelation coverage maps improve communication with high-Doppler UEs, for example, by increasing data rates. The aspects include the execution of channel measurements for collecting autocorrelation information, crowdsourced channel autocorrelation information, channel autocorrelation requests from vehicles / UEs, and response messages from the network, etc., as further described herein.

[0090] Figure 6 Figure 600 illustrates examples of pilot periodicity for channel autocorrelation measurements in radio coverage maps, representing various aspects. Figure 600 shows example configurations for aspects such as configuration 650, configuration 660, configuration 670, and configuration 680. In each aspect, the periodicity may be based on one or more of the various configurations in Figure 600. In each aspect, network nodes (e.g., base station 604, gNB, etc.) and vehicles / UEs (e.g., in vehicle 603 or including “UE 602”) may be configured to communicate with each other.

[0091] In the example exemplified for configuration 650, a network node (e.g., base station 604, gNB, etc.) may be configured to signal an instance of configuration 618 (e.g., UE 602 may be configured to periodically transmit / send / provide channel autocorrelation measurement pilots (via channel autocorrelation measurement pilot transmission 608) to a vehicle / UE (e.g., may be in vehicle 603 or may include “UE 602”), and configuration 618 may be based on one or more of the following: (i) channel autocorrelation map update indication 624, (ii) connection established by UE 602 with network node (e.g., base station 604) 622, and / or (iii) location information associated with UE 602 (described in further detail herein) associated with a selected road area of ​​road 616. In various aspects, base station 604 may be configured to randomly / pseudo-randomly select a vehicle / UE (e.g., vehicle 603 and / or UE 602 including that vehicle) among UEs connected to base station 604. In various aspects, configuration 618 may instruct periodicity 620 for at least one channel autocorrelation measurement pilot transmission 608 based on a time period length or the period of one or more time slots 606. In such aspects, at least one channel autocorrelation measurement pilot transmitted in a given channel autocorrelation measurement pilot transmission 608 may include at least one DMRS symbol for UE 602 or at least one symbol having a longer length than the DMRS symbol for UE 602 to increase measurement accuracy. In some aspects, configuration 618 may be pre-configured at UE 602.

[0092] In the example exemplified for configuration 660, periodicity 620 can be as small as a time slot or as small as the time period of a time slot, as shown for the channel autocorrelation measurement pilot (transmitted via channel autocorrelation measurement pilot 610).

[0093] In the example exemplified for configuration 670, periodicity 620 may be indicated by configuration 618, which may be based on one or more of the following: (i) channel autocorrelation map update indication 624, (ii) connection 622 established by UE 602 with a network node (e.g., base station 604), and / or (iii) location information associated with UE 602 (described in further detail herein) is associated with a selected road area of ​​road 616. In configuration 670, configuration 618 may instruct UE 602 to periodically transmit / send / provide channel autocorrelation measurement pilots (via channel autocorrelation measurement pilot transmission 612) to the network node (e.g., base station 604) according to periodicity 620 as described above, wherein each channel autocorrelation measurement pilot (via channel autocorrelation measurement pilot transmission 612) includes more than one / multiple time slots. In other words, configuration 618 can instruct at least one channel autocorrelation measurement pilot (transmitted via channel autocorrelation measurement pilot 612) to include multiple time slots, and at least one channel autocorrelation measurement pilot (transmitted via channel autocorrelation measurement pilot 612) can include multiple time slots. Therefore, having multiple time slots for at least one channel autocorrelation measurement pilot (transmitted via channel autocorrelation measurement pilot 612) can result in more accurate channel correlation, and it can also vary with the number of time slots. In all respects, the number of time slots can be pre-configured at UE 602 by configuration 618.

[0094] In the example exemplified for configuration 680, periodicity 620 may be indicated by configuration 618, which instructs UE 602 to periodically transmit / send / provide channel autocorrelation measurement pilots to a network node (e.g., base station 604) according to periodicity 620 (performed via channel autocorrelation measurement pilot transmission using connection 622). In such a configuration, periodicity 620 may be based on distance intervals traversed by UE 602. d (For example, as in vehicle 603 and / or as including the vehicle), where the distance interval traversed by UE 602 d Based on the distance interval set by UE 602 d The measurement is performed. UE 602 can be configured to transmit / send / provide at least one channel autocorrelation measurement pilot at an instantaneous velocity 614 experienced by UE 602. In various aspects, based on distance spacing d The periodicity 620 can be every few meters, or some other distance value / length. Since the vehicle / UE can be configured to calculate the distance traveled / traversed, the vehicle / UE can base its distance interval on the periodicity 620. d To transmit / send / provide channel autocorrelation measurement pilots. In various aspects, distance spacing... d It can be pre-configured at UE 602 by configuration 618.

[0095] Figure 7 Figure 700 is an example of channel autocorrelation location information in a radio coverage map, illustrating various aspects. Figure 700 is shown in the context of UE 702 and network nodes (e.g., base station 704, gNB, etc.).

[0096] In various aspects, UE 702 may be in, or may include, the vehicle 722, as shown for UE 703. Vehicle 722 may travel / cross road 720 at a rate or speed 726. In various aspects, location information may be associated with UE 702. In some aspects, the location information may also be associated with the road 720 traversed by UE 702. The location information may be location information 716 (associated with UE 702) within the road boundary of road 720, and in some aspects, the location information may be additional location information 718 excluding the road boundary of road 720.

[0097] Location information 716 may be further associated with at least a portion of the region of the channel autocorrelation map. In various aspects, location information 716 associated with UE 702 may include at least one of the following: area identifier (ID) 706, GNSS location associated with GNSS 708, segment identifier 710 of road 720, lane identifier 712 and / or lane identifier 714 of road 720, vehicle information 724 associated with UE 702 and / or vehicle 722 (e.g., brand, model, year, etc.), and / or a set of transmission parameters 728 of UE 702 (e.g., RF chain, etc.).

[0098] Figure 8 Figure 800 illustrates examples of channel autocorrelation configurations for various aspects of a radio coverage map. Figure 800 shows various example configurations for such aspects in the context of UE 802, attached UE 803, and network nodes (e.g., base station 804, gNB, etc.): configuration 850, configuration 860, and configuration 870. The configurations shown in Figure 800 can be... Figure 5 Further aspects of the call flowchart 500 in the diagram. As described, aspects may provide a channel autocorrelation diagram 818 for configuring 860.

[0099] In configuration 850, UE 802 can be configured to transmit / provide and base station 804 can be configured to receive at least one channel autocorrelation pilot 806 (e.g., as...). Figure 5(Similarly described in (510)). Base station 804 may be configured (at 808) to generate a channel autocorrelation map 818 based on performing at least one channel autocorrelation measurement using at least one antenna pair of base station 804. In various aspects, the execution of at least one channel autocorrelation measurement may be based on at least one channel autocorrelation measurement pilot 806. In various aspects, the channel autocorrelation map 818 may be stored locally near base station 804 or globally on a server at a different geographical location than base station 804.

[0100] UE 802 may be configured to receive and base station 804 may be configured to transmit / provide at least one channel autocorrelation value 810 of a channel autocorrelation map 818 generated (at 808). In various respects, the channel autocorrelation map 818 and / or at least one channel autocorrelation value 810 may be based on at least one channel autocorrelation measurement pilot 806, which indicates (e.g., in...) Figure 5 The channel information of the communication channel identified in (at position 508) and the location information associated with UE 802.

[0101] In configuration 860, base station 804 can be configured to select multiple UEs (e.g., UE 802, additional UE 803, and / or other UEs) for providing channel autocorrelation measurement pilots. In configuration 860, base station 808 can be configured to perform crowdsourcing for receiving at least one channel autocorrelation measurement.

[0102] Base station 804 can be configured to select multiple UEs, such as UE 802, additional UE 803, and / or other UEs, via signaling 824. In various respects, when base station 804 calculates, for example, a channel autocorrelation update expected or scheduled for a certain location, it can trigger the transmission / offering of signaling 824 for UE selection, which may be associated with an indication thereof (e.g., Figure 6 The channel autocorrelation diagram update indication 624 shown is associated with this. In all aspects, when a vehicle / UE (e.g., UE 802, additional UE 803 and / or other UEs) establishes a connection with base station 804 (e.g., Figure 6 In connection 622), and when base station 804 randomly / pseudo-randomly selects the vehicle / UE (e.g., UE 802, additional UE 803, and / or other UEs) to transmit the channel autocorrelation measurement pilot, signaling 824 for UE selection may be triggered. In each respect, when base station 804 obtains location information associated with the UE in a certain area (e.g., ... Figure 7 When the location information 716 is received, the sending / providing of signaling 824 for UE selection can be triggered.

[0103] In various aspects, the transmission / providation of signaling 824 for UE selection may include configuration (e.g., Figure 5 Configuration 506 in the middle; Figure 6 Configuration 618 in the configuration; or other activation signaling), and may be based on one or more of the following: (i) channel autocorrelation graph update indication, (ii) connection established by UE 802 with network node (e.g., base station 804), and / or (iii) location information associated with UE 802 (regarding Figure 7 (As described above) is associated with road areas for road selection.

[0104] As described above with respect to configuration 860, base station 808 may be configured to perform crowdsourcing for receiving at least one channel autocorrelation measurement 816. Base station 808 may be configured to broadcast signaling including a broadcast autocorrelation measurement pilot 812. In various respects, the header of the broadcast autocorrelation measurement pilot 812 may include an index indicating the performance of the at least one channel autocorrelation measurement 816.

[0105] UE 802 and / or additional UE 803 may be configured to receive broadcast autocorrelation measurement pilot 812 and, based on the measurement configuration, perform at least one channel autocorrelation measurement 816 (at 814) based on the broadcast autocorrelation measurement pilot 812. In various aspects, vehicles / UEs (e.g., UE 802, additional UE 803, and / or other UEs) may voluntarily calculate at least one channel autocorrelation measurement 816 based on the broadcast autocorrelation measurement pilot 812 and are configured to report at least one channel autocorrelation measurement 816, along with an indication of corresponding location information, back to base station 804.

[0106] Therefore, based on the described aspects, base station 804 can be configured to generate, over a period of time (e.g., as described at 808 in configuration 850), a local channel autocorrelation map indicating the channel autocorrelation within the cell of base station 804. In some aspects, in order to generate the channel autocorrelation map (at 808), base station 804 can be configured to utilize interpolation for locations where channel autocorrelation has not yet been measured.

[0107] In configuration 870, UE 802 may be configured to request channel autocorrelation values ​​(e.g., 810 as described in configuration 850). UE 802 may be configured to transmit / provide, and base station 804 may be configured to receive, a request message 820 indicating that UE 802 requests at least one channel autocorrelation value from a channel autocorrelation map. In various aspects, request message 820 may include location information associated with UE 802, and the location information associated with the UE may include a district identifier, GNSS location, road segment identifier, and / or road lane identifier (as described herein). Figure 7Location information associated with UE 802 may be included in at least one of the following: BSR, header of request message 820, first communication via control channel, or second communication via unicast data channel.

[0108] UE 802 may be configured to receive, and base station 804 may be configured to send / provide a request response message 822 based on request message 820, which may indicate at least one channel autocorrelation value of the channel autocorrelation plot. The request response message may be included in a control channel or a unicast data channel, and request response message 822 may include at least one of an index indicating the statistical confidence of at least one channel autocorrelation value, a quantized statistical distribution of at least one channel autocorrelation value, etc.

[0182] Network nodes and UEs in a wireless communication network can communicate in various configurations utilizing coverage maps. Coverage maps enable a variety of applications, such as UE positioning, route selection, remote driving, emergency vehicle service / management, etc. Communication quality statistics for coverage maps can include uplink and downlink rates per user (which can be calculated, for example, by packet TBS and packet decoding error rate), packet delay, RSSI for each Tx-Rx antenna pair, etc. Channel autocorrelation can also be an influential factor in wireless communication, such as channel prediction and mobile communication. Channel autocorrelation-related information can be environment-dependent and therefore can be related to, for example, the location of the UE. Additionally, for vehicle communication, adaptive rate transmission can be based on channel autocorrelation, as is the case in MIMO scenarios. If the channel autocorrelation is known, using adaptive rate transmission can achieve data rates up to 10 times higher for MU-MIMO vehicle communication than without adaptive rate transmission, and such high data rates can be used for related applications, such as video streaming, etc. However, while channel autocorrelation can enable adaptive rate transmission to enhance vehicle communication performance in high Doppler MIMO scenarios, radio coverage maps lack enhancements from channel autocorrelation.

[0183] This document provides aspects for channel autocorrelation in radio coverage maps. Channel measurements for collecting autocorrelation information can be performed by network nodes (e.g., base stations, gNBs, etc.) and / or UEs / vehicles based on measurement pilots to generate channel autocorrelation maps that will be used for communication between network nodes and / or UEs / vehicles. Crowdsourced channel autocorrelation information can be obtained by network nodes from multiple UEs / vehicles. In some examples, channel autocorrelation information / values ​​from the channel autocorrelation map can be requested by the UE / vehicle, and the network node can provide / send a corresponding response message. For UE / vehicle communication, collection of autocorrelation information in areas outside road boundaries can be excluded, and the channel autocorrelation map can be stored locally near the network node or globally on servers at different geographical locations. The aspects provide methods for generating channel autocorrelation coverage maps by collecting channel autocorrelation information and adding such information to radio coverage maps, which improve communication with high-Doppler UEs, for example, by increasing data rates.

Therefore, the claims are not limited to the aspects described herein but should be given the full scope consistent with the language of the claims. Unless specifically stated otherwise, references to elements in the singular form do not mean “one and only one” but rather “one or more.” Terms such as “if,” “when,” and “simultaneously” do not imply a direct temporal relationship or reaction. That is, these phrases, such as “when,” do not imply an immediate action in response to the occurrence of an action or during the occurrence of an action, but simply suggest that if a condition is met, then the action will occur, without requiring a specific or immediate time limit for the occurrence of 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 superior to 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 A, B, and C", "one or more of A, B, and C", and "A, B, C, or any combination thereof" include any combination of A, B, and / or C, which may include multiple A, multiple B, or multiple C.

A set should be interpreted as a collection of elements, where the number of elements is one or more. Therefore, for a set of X, X will include one or more elements. When at least one processor is configured to execute a set of functions, the at least one processor is configured to execute the set of functions individually or in any combination. Therefore, each of the at least one processor can be configured to execute a specific subset of the set of functions, wherein the subset is the complete set, a suitable subset of the set, or an empty subset of the set. A processor may be referred to as a processor circuit. A memory / memory module may be referred to as a memory circuit. If a first device receives data from or sends data to a second device, data can be received / sent directly between the first and second devices, or indirectly between the first and second devices through a set of devices. A device configured to "output" or "provide" data (such as transmission, signaling, or messaging) may, for example, transmit data using a transceiver, or may transmit the data to the device that sent the data.A device configured to "acquire" data (such as, transmit, signal, or message) may, for example, receive the data using a transceiver, or may obtain the data from a device receiving the data. Information stored in memory includes instructions and / or data. All structural and functional equivalents of the elements throughout the various aspects described herein that are known to those skilled in the art or will later be known are expressly incorporated herein by reference and are covered by the claims. Furthermore, nothing disclosed herein is intended to be offered to the public, whether or not such disclosure is explicitly recited in the claims. The words "module," "mechanism," "element," "device," etc., cannot replace the word "component." Therefore, no claim element will be construed as a functional component unless the element is explicitly recited using the phrase "component for..."
