RADIO MAP INFORMATION ASSOCIATING PORTIONS OF A RADIO MAP WITH CORRESPONDING ROADWAY AREASTECHNICAL FIELD
[0001] Aspects of the present disclosure relate generally to wireless communication systems, and more particularly, to radio map information. Some features may enable and provide improved communications, including radio map information associating portions of a radio map with corresponding roadway areas.
[0002] INTRODUCTION
[0003] Wireless communication networks are widely deployed to provide various communication services such as voice, video, packet data, messaging, broadcast, and the like. These wireless networks may be multiple-access networks capable of supporting multiple users by sharing the available network resources. Such networks may be multiple access networks that support communications for multiple users by sharing the available network resources.
[0004] A wireless communication network may include several components. These components may include wireless communication devices, such as network nodes (or node Bs or base stations) that may support communication for a number of user equipments (UEs) . A UE may communicate with a network node via downlink and uplink. The downlink (or forward link) refers to the communication link from the network node to the UE, and the uplink (or reverse link) refers to the communication link from the UE to the network node.
[0005] Performance on both the downlink and uplink may vary by location. For example, wireless communication rate varies with blockage and environment and is often dependent on the location. Further, infrastructure providing services of or in association with wireless networks is typically distributed non-uniformly within any particular service area. For example, communication resources of wireless network infrastructure are generally distributed geographically non-uniformly, and change with time. As an example, some areas may have denser network node deployments while other areas may have less dense network node deployments. Similarly, edge computation facilities and resources are distributed geographically non-uniformly. Issues with respect to diminution in communication performance and interruptions in association with traveling vehicles may be exacerbated by the geographically non-uniform distribution of communication resources, blockage, and environment.

[0030] The detailed description set forth below, in connection with the appended drawings, is intended as a description of various configurations and is not intended to limit the scope of the disclosure. Rather, the detailed description includes specific details for the purpose of providing a thorough understanding of the inventive subject matter. It will be apparent to those skilled in the art that these specific details are not required in every case and that, in some instances, well-known structures and components are shown in block diagram form for clarity of presentation.
[0031] The present disclosure provides systems, apparatus, methods, and computer-readable media that support radio map information associating portions of a radio map with corresponding roadway areas. Radio map information according to some aspects of the disclosure may, for example, include network node configuration information for one or more network nodes identified as associated with at least one roadway, location-specific radio statistic information for one or more locations on at least one roadway, radio frequency (RF) sensing information for at least one roadway, or any combination thereof.
[0032] Network node configuration information of the radio map information of some aspects may, for example, include network node identification for network nodes, network node location for the network nodes, road segment information for road segments of roadways associated with the network nodes, activation status of network nodes, etc. Location-specific radio statistic information of the radio map information of some aspects may, for example, include wireless communication per-user uplink rate information, wireless communication per-user downlink rate information, wireless communication reliability information, wireless communication packet latency information, wireless communication received signal strength indicator (RSSI) information, vehicle categorization information corresponding to one or more capabilities of a vehicle associated with the location-specific radio statistic information, road segment information for a location associated with the location-specific radio statistic information, etc. for one or more locations on at least one roadway. RF sensing information of the radio map information of some aspects may, for example, include RF sensing information indicating one or more aspects of vehicle traffic with respect to a location on a roadway within the region, vehicle position information calibrated with RF sensing, RF sensing information indicating vehicle speed, etc.
[0033] In accordance with some aspects, network nodes of one or more wireless networks providing communication services with respect to an area may collect or otherwise obtain radio map information with respect to roadways of the area, such as for reporting or otherwise providing to one or more routing systems. A network node may, for example, transmit one or more messages including a portion of the radio map information to a routing system associated with a wide area (for example, metropolitan, regional, state, country, global, etc., referred to herein as a “region” ) radio map associated with roadway areas of the region in which communications are provided by the network node, such as for use with respect to the radio map. Additionally or alternatively, a network node may provide signaling, a trigger, etc. to user equipments (UEs) operating within or otherwise associated with the region for one or more messages comprising aspects of the radio map information.
[0034] A routing system of some examples may utilize radio map information of some examples in generating, updating, or otherwise maintaining a radio map with respect to the region. The routing system may, for example, update one or more aspects of a database associated with the radio map with the radio map information. According to some examples, a routing system may provide radio map information reporting periodicity information to network nodes associated with the region. Additionally or alternatively, a routing system may provide signaling, a trigger, etc. to network nodes associated with the region for one or more messages comprising aspects of the radio map information.
[0035] A radio map maintained using radio map information according to some aspects of the disclosure may, for example, be utilized with respect to facilitating vehicle routing with communication constraints. Vehicle routing utilizing a radio map maintained with radio map information of some examples may generate one or more communication-aware routes for traveling between locations (for example, selected origination and destination points) by considering one or more aspects of the network node configuration information, the location-specific radio statistic information, the RF sensing information, or a combination thereof.
[0036] Particular implementations of the subject matter described in this disclosure may be implemented to realize one or more of the following potential advantages or benefits. In some aspects, the present disclosure provides techniques for generating, dynamically updating, and otherwise maintaining radio maps for a region, where the information of the radio map is associated with corresponding roadway areas of the region. A radio map maintained with radio map information comprising network node configuration information, location-specific radio statistic information, and RF sensing information of some examples provides robust information regarding the communication environment and various aspects of communications (for example, reliability, latency, etc. ) with respect to roadway locations within a region. Although the region may be relatively large, a radio map maintained with radio map information of some examples may nevertheless be managed in size by collecting and using radio map information for locations within the boundaries of the roadways (for example, omitting locations outside the boundaries of the roadways) . A radio map of some examples may thus practicability encompass all roadways and network nodes of a wireless communication system within a region. Such a radio map may, for example, be maintained centrally with respect to a region, such as by a routing system associated with the region.
[0037] Radio maps of examples may be efficiently and effectively maintained using information regarding the communication environment, various aspects of communications with respect to roadway locations, etc. In some examples, a routing system or other system maintaining radio map information may determine how frequently to update the radio map, what aspects of the radio map are to be updated, etc. based on the nature of RF information. For example, variations in RF data collected over time may be analyzed in determining whether the RF environment has changed, and be used to adjust one or more aspects, such as how many devices report various information, when devices report various information, etc., of radio map information updating.
[0038] Radio maps maintained with consideration of various metrics, such as reliability, latency, etc. provided by or derived from the radio map information of some examples, are well suited for application with respect to facilitating vehicle routing for better communication quality. For example, radio maps for a region, where the information of the radio map is associated with corresponding roadway areas of the region according to aspects of the disclosure, may be efficiently and effectively utilized by a routing system for communication-aware routing of vehicles. Wireless communications facilitated in association with radio map information according to aspects of the disclosure may additionally or alternatively include transmitting messages for traffic conditions, road information, accidents, emergency vehicles, road construction work, etc.
[0039] Radio maps for a region, where the information of the radio map is associated with corresponding roadway areas of the region according to some examples, facilitates predictable and robust communication, such as may support a variety of applications and use scenarios placing significant demand upon wireless networks. For example, a radio map maintained with radio map information of some examples may be utilized for supporting uninterrupted, reliable, and low-latency transmission of messages for high definition (HD) maps (for example, highly detailed, highly accurate maps that represent location data including various features, such as lane markings, road edges, signage, etc. ) , such as for autonomous driving and tele-operated driving applications. According to some examples, crowdsourced HD mapping may be supported, such as using information regarding communication latency, reliability, etc. to determine when to upload HD map information from vehicles, when to download portions of HD maps to vehicles, or a combination thereof, such as to minimize service interruptions due to congested network conditions.
[0040] This disclosure relates generally to providing or participating in authorized shared access between two or more wireless devices in one or more wireless communications systems, also referred to as wireless communications networks. In various implementations, the techniques and apparatus may be used for wireless communication networks such as code division multiple access (CDMA) networks, time division multiple access (TDMA) networks, frequency division multiple access (FDMA) networks, orthogonal FDMA (OFDMA) networks, single-carrier FDMA (SC-FDMA) networks, LTE networks, GSM networks, 5th Generation (5G) or new radio (NR) networks (sometimes referred to as “5G NR” networks, systems, or devices) , as well as other communications networks. As described herein, the terms “networks” and “systems” may be used interchangeably.
[0041] For clarity, certain aspects of the apparatus and techniques may be described below with reference to example 5G NR implementations or in a 5G-centric way, and 5G terminology may be used as illustrative examples in portions of the description below; however, the description is not intended to be limited to 5G applications.
[0042] Moreover, it should be understood that, in operation, wireless communication networks adapted according to the concepts herein may operate with any combination of licensed or unlicensed spectrum depending on loading and availability. Accordingly, it will be apparent to a person having ordinary skill in the art that the systems, apparatus and methods described herein may be applied to other communications systems and applications than the particular examples provided.
[0043] While aspects and implementations are described in this application by illustration to some examples, those skilled in the art will understand that additional implementations and use cases may come about in many different arrangements and scenarios. Innovations described herein may be implemented across many differing platform types, devices, systems, shapes, sizes, packaging arrangements. For example, implementations or uses may come about via integrated chip implementations or other non-module-component based devices (e.g., end-user devices, vehicles, communication devices, computing devices, industrial equipment, retail devices or purchasing devices, medical devices, AI-enabled devices, etc. ) . While some examples may or may not be specifically directed to use cases or applications, a wide assortment of applicability of described innovations may occur. Implementations may 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 described aspects. In some practical settings, devices incorporating described aspects and features may also necessarily include additional components and features for implementation and practice of claimed and described aspects. It is intended that innovations described herein may be practiced in a wide variety of implementations, including both large devices or small devices, chip-level components, multi-component systems (e.g., radio frequency (RF) -chain, communication interface, processor) , distributed arrangements, end-user devices, etc. of varying sizes, shapes, and constitution.
[0044] FIG. 1 is a block diagram illustrating details of an example wireless communication system according to one or more aspects. The wireless communication system may include wireless network 100. Wireless network 100 may, for example, include a 5G wireless network. As appreciated by those skilled in the art, components appearing in FIG. 1 are likely to have related counterparts in other network arrangements including, for example, cellular-style network arrangements and non-cellular-style-network arrangements (e.g., device to device or peer to peer or ad hoc network arrangements, etc. ) .
[0045] Wireless network 100 illustrated in FIG. 1 includes a number of network nodes 105 and other network entities. A network node may be a station that communicates with the UEs and may also be referred to as an evolved node B (eNB) , a next generation eNB (gNB) , a base station, an access point, and the like. Each network node 105 may provide communication coverage for a particular geographic area. In documents from an organization named “3rd Generation Partnership Project” (3GPP) , the term “cell” may refer to this particular geographic coverage area of a network node or a network node subsystem serving the coverage area, depending on the context in which the term is used. In implementations of wireless network 100 herein, network nodes 105 may be associated with a same operator or different operators (e.g., wireless network 100 may include a plurality of operator wireless networks) . Additionally, in implementations of wireless network 100 herein, network node 105 may provide wireless communications using one or more of the same frequencies (e.g., one or more frequency bands in licensed spectrum, unlicensed spectrum, or a combination thereof) as a neighboring cell. In some examples, an individual network node 105 or UE 115 may be operated by more than one network operating entity. In some other examples, each network node 105 and UE 115 may be operated by a single network operating entity.
[0046] A network node may provide communication coverage for a macro cell or a small cell, such as a pico cell or a femto cell, or other types of cell. A macro cell generally covers a relatively large geographic area (e.g., several kilometers in radius) and may allow unrestricted access by UEs with service subscriptions with the network provider. A small cell, such as a pico cell, would generally cover a relatively smaller geographic area and may allow unrestricted access by UEs with service subscriptions with the network provider. A small cell, such as a femto cell, would also generally cover a relatively small geographic area (e.g., a home) and, in addition to unrestricted access, may also provide restricted access by UEs having an association with the femto cell (e.g., UEs in a closed subscriber group (CSG) , UEs for users in the home, and the like) . A network node for a macro cell may be referred to as a macro network node. A network node for a small cell may be referred to as a small cell network node, a pico network node, a femto network node or a home network node. In the example shown in FIG. 1, network nodes 105d and 105e are regular macro network nodes, while network nodes 105a-105c are macro network nodes enabled with one of 3 dimension (3D) , full dimension (FD) , or massive multiple input, multiple output (MIMO) . Network nodes 105a-105c take advantage of their higher dimension MIMO capabilities to exploit 3D beamforming in both elevation and azimuth beamforming to increase coverage and capacity. Network node 105f is a small cell network node which may be a home node or portable access point. A network node may support one or multiple (e.g., two, three, four, and the like) cells.
[0047] Wireless network 100 may support synchronous or asynchronous operation. For synchronous operation, the network nodes may have similar frame timing, and transmissions from different network nodes may be approximately aligned in time. For asynchronous operation, the network nodes may have different frame timing, and transmissions from different network nodes may not be aligned in time. In some scenarios, networks may be enabled or configured to handle dynamic switching between synchronous or asynchronous operations.
[0048] UEs 115 are dispersed throughout the wireless network 100, and each UE may be stationary or mobile. It should be appreciated that, although a mobile apparatus is commonly referred to as a UE in standards and specifications promulgated by the 3GPP, such apparatus may additionally or otherwise be referred to by those skilled in the art as a mobile station (MS) , a subscriber station, a mobile unit, a subscriber unit, a wireless unit, a remote unit, a mobile device, a wireless device, a wireless communications device, a remote device, a mobile subscriber station, an access terminal (AT) , a mobile terminal, a wireless terminal, a remote terminal, a handset, a terminal, a user agent, a mobile client, a client, a gaming device, an augmented reality device, vehicular component, vehicular device, or vehicular module, or some other suitable terminology. Within the present document, a “mobile” apparatus or UE need not necessarily have a capability to move, and may be stationary. Some non-limiting examples of a mobile apparatus, such as may include implementations of one or more of UEs 115, include a mobile, a cellular (cell) phone, a smart phone, a session initiation protocol (SIP) phone, a wireless local loop (WLL) station, a laptop, a personal computer (PC) , a notebook, a netbook, a smart book, a tablet, and a personal digital assistant (PDA) , a vehicle-to-everything (V2X) module, an in-vehicle telemetrics device, mobile hotspot, vehicle infotainment system, advanced driver assistance system (ADAS) , a navigation system, a media player, a virtual assistant device, etc. A mobile apparatus may additionally be an IoT or “Internet of everything” (IoE) device such as an automotive or other transportation vehicle, a satellite radio, a global positioning system (GPS) device, a global navigation satellite system (GNSS) device, a logistics controller, a drone, a multi-copter, a quad-copter, a smart energy or security device, a solar panel or solar array, industrial automation and enterprise devices; consumer and wearable devices, such as eyewear, a wearable camera, a smart watch, a health or fitness tracker, a mammal implantable device, gesture tracking device, medical device, a digital audio player (e.g., MP3 player) , a camera, a game console, etc.; and digital home or smart home devices such as a home audio, video, and multimedia device, an appliance, a sensor, a vending machine, intelligent lighting, a home security system, a smart meter, etc. In one aspect, a UE may be a device that includes a Universal Integrated Circuit Card (UICC) . In another aspect, a UE may be a device that does not include a UICC. In some aspects, UEs that do not include UICCs may also be referred to as IoE devices. UEs 115a-115d of the implementation illustrated in FIG. 1 are examples of mobile smart phone-type devices accessing wireless network 100 A UE may also be a machine specifically configured for connected communication, including machine type communication (MTC) , enhanced MTC (eMTC) , narrowband IoT (NB-IoT) and the like. UEs 115e-115k illustrated in FIG. 1 are examples of various machines configured for communication that access wireless network 100.
[0049] A mobile apparatus, such as UEs 115, may be able to communicate with any type of the network nodes, whether macro network nodes, pico network nodes, femto network nodes, relays, and the like. In FIG. 1, a communication link (represented as a lightning bolt) indicates wireless transmissions between a UE and a serving network node, which is a network node designated to serve the UE on the downlink or uplink, or desired transmission between network nodes, and backhaul transmissions between network nodes. UEs may operate as network nodes (for example, base stations) in some scenarios. Backhaul communication between network nodes of wireless network 100 may occur using wired or wireless communication links.
[0050] In operation at wireless network 100, network nodes 105a-105c serve UEs 115a and 115b using 3D beamforming and coordinated spatial techniques, such as coordinated multipoint (CoMP) or multi-connectivity. Macro network node 105d performs backhaul communications with network nodes 105a-105c, as well as small cell, network node 105f. Macro network node 105d also transmits multicast services which are subscribed to and received by UEs 115c and 115d. Such multicast services may include mobile television or stream video, or may include other services for providing community information, such as weather emergencies or alerts, such as Amber alerts or gray alerts.
[0051] Wireless network 100 of implementations supports mission critical communications with ultra-reliable and redundant links for mission critical devices, such UE 115e, which is a drone. Redundant communication links with UE 115e include from macro network nodes 105d and 105e, as well as small cell network node 105f. Other machine type devices, such as UE 115f (thermometer) , UE 115g (smart meter) , and UE 115h (wearable device) may communicate through wireless network 100 either directly with network nodes, such as small cell network node 105f, and macro network node 105e, or in multi-hop configurations by communicating with another user device which relays its information to the network, such as UE 115f communicating temperature measurement information to the smart meter, UE 115g, which is then reported to the network through small cell network node 105f. Wireless network 100 may also provide additional network efficiency through dynamic, low-latency time division duplex (TDD) communications or low-latency frequency division duplex (FDD) communications, such as in a vehicle-to-vehicle (V2V) mesh network between UEs 115i-115k communicating with macro network node 105e.
[0052] FIG. 2 is a block diagram illustrating examples of network node 105 and UE 115 according to one or more aspects. Network node 105 and UE 115 may be any of the network nodes and one of the UEs in FIG. 1. For a restricted association scenario (as mentioned above) , network node 105 may be small cell network node 105f in FIG. 1, and UE 115 may be UE 115c or 115d operating in a service area of network node 105f, which in order to access small cell network node 105f, would be included in a list of accessible UEs for small cell network node 105f. Network node 105 may also be a network node of some other type. As shown in FIG. 2, network node 105 may be equipped with antennas 234a through 234t, and UE 115 may be equipped with antennas 252a through 252r for facilitating wireless communications.

In accordance with some examples, various aspects of information sensed in the RF environment may be combined with or otherwise used in combination with other information with respect to wireless communications system 300. For example, vehicle position information of the RF sensing information may be used for calibration of other location information (for example, GNSS position information) for providing increased accuracy.

Aspects of the RF sensing information may be utilized by routing system 325 as a trigger for changing a threshold for how many devices (for example, instances of UE 315) need to report various information (for example, HD map information, radio map information, etc. ) before an update or other action is performed (for example, radio map update, HD map update, etc. ) . According to some examples, one or more thresholds with respect to a number of devices reporting information to the routing system may be adjusted in correspondence with one or more aspect of the RF sensing information, such as by lowering a threshold as the RF sensing information indicates less vehicle traffic density and increasing a threshold as the RF sensing information indicates higher vehicle traffic density.
[0097] Transmitter 322 is configured to transmit reference signals, synchronization signals, control information, and data to one or more other devices, and receiver 323 is configured to receive reference signals, control information, and data from one or more other devices.

In some implementations, transmitter 322 and receiver 323 may be integrated in one or more transceivers.
[0098] Network node configuration information, location-specific radio statistic information, RF sensing information, and road segment ID information is shown separately in the example illustrated in FIG. 3. In accordance with some examples, any or all of the Network node configuration information, location-specific radio statistic information, RF sensing information, and road segment ID information, or portions thereof, may be provided in a combined implementation at any of all of network node 305, UE 315, and routing system 325 according to aspects of the disclosure.
[0099] In some implementations, wireless communications system 300 implements a 5G NR network. For example, wireless communications system 300 may include multiple 5G-capable UEs 115 and multiple 5G-capable network nodes 105, such as UEs and network nodes configured to operate in accordance with a 5G NR network protocol such as that defined by the 3GPP.
[0100] During operation of wireless communications system 300 according to some aspects, radio map information is provided associating portions of a radio map with corresponding roadway areas. In operation according to some examples, network node 305, UE 315, or a combination thereof may obtain (for example, measure, monitor, compute, derive, receive, etc. ) various aspects of radio map information (for example, network node configuration information, location-specific radio statistic information, RV sensing information, road segment ID information, or any combination thereof) , such as for use with respect to generating, updating, or otherwise maintaining a radio map with respect to a region (for example, a wide area, such as a metropolitan area or region, a state, a country, global, etc. ) . Radio map information may, for example, be provided to routing system 325 for updating one or more aspects of a database associated with the radio map with the radio map information. Such a radio map, maintained using radio map information according to some aspects of the disclosure, may be utilized with respect to facilitating vehicle routing with communication constraints.
[0101] FIG. 4 is a ladder diagram illustrating example operations implemented for providing radio map information associating portions of a radio map with corresponding roadway areas according to one or more aspects. UE 315 shown in the example of FIG. 4 corresponds to UE 315 of FIG. 3 and may comprise a vehicle, one or more devices associated with a vehicle or otherwise operating in association with a roadway area for which communication services are provided by network node 305, or any combination there of. Network node 305 shown in the example of FIG. 4 corresponds to network node 305 of FIG. 3 and may comprise an aggregated or disaggregated implementation of a network node configured to provide communication services with respect to one or more roadways. Routing system 325 shown in the example of FIG. 4 corresponds to routing system 325 of FIG. 3 and may comprise one or processor-based systems configured to obtain and utilize radio map information according to some aspects of the disclosure.
[0102] Routing system 325 of some examples is operable to maintain (for example, generate, update, or otherwise manage under control of radio map logic 326) a database of network nodes within a region. For example, network node configuration information 327a as maintained by routing system 325 may include information for all network nodes which provide communication services with respect to one or more roadways within the region, such as may be utilized with respect to computing routes of vehicles when taking communication into consideration. Network node configuration information 327a may, for example, include information regarding the network nodes and their operation, such as network node location, roadways for which communication services are provided by a respective network node, road segments for which communication services are provided by a respective network node, operating status of each network node, communication capabilities of respective network nodes, etc. Network nodes (for example, network node 305) are enabled to transmit messages to and receive messages from routing system 325 (for example, via the Internet, one or more wireless or wireline links, etc. ) , such as to facilitate maintaining the database of network nodes, to confirm updates to the database, etc.
[0103] In operation according to the example illustrated in FIG. 4, routing system 325 obtains network node configuration information of the radio map information, such as may be utilized with respect to maintaining a database of network nodes within a region. Routing system 325 of the illustrated example receives or otherwise obtains network node configuration information in communication 411 (for example, one or more messages of network node configuration message (s) 381) transmitted or otherwise provided by network node 305. Communication 411 may, for example, include network node ID for the network node, network node IDs for network nodes neighboring the network node, network node location, network node operating status, roadway IDs for roadways associated with the network node, road segment IDs for road segments associated with the network node, network node operating status, network node communication capabilities, or any combination thereof. In accordance with some examples, the network node configuration information may include information with respect to network node 305, information with respect to network nodes neighboring or otherwise located in proximity to network node 305, or a combination thereof.
[0104] Communication of network node configuration information of the radio map information (for example, communication 411) may be provided (for example, under control of radio map logic 306) in association with a network node being deployed in wireless communications system 300. For example, as part of a network node initialization procedure, a network node (for example, network node 305) may operate to obtain various information of the network node configuration information of examples herein and provide that information to routing system 325. A newly deployed network node may, for example, be added to the database of network nodes by routing system 325 in accordance with such messages.
[0105] In operation according to the example illustrated in FIG. 4, network node 305 obtains radio map information control, such as may be utilized with respect to control aspects of providing (for example, collecting, obtaining, generating, receiving, transmitting, etc. ) radio map information of some examples. Network node 305 of the illustrated example receives or otherwise obtains radio map information control signaling in communication 421 (for example, one or more messages of network node configuration message (s) 381, location-specific radio statistic message (s) 382, RF sensing message (s) 383, road segment ID message (s) 384, or any combination thereof) transmitted or otherwise provided by routing system 325. Communication 421 may, for example, include information with respect to radio map information to be obtained / reported, periodicity information for obtaining / reporting radio map information, one or more triggers for obtaining / reporting radio map information, one or more thresholds for obtaining / reporting radio map information, etc., where the aforementioned radio map information may comprise network node configuration information, location-specific radio statistic information, RF sensing information, road segment ID information, or any combination thereof.
[0106] Communication of network node configuration information (for example, communication 411) may additionally or alternatively be provided in association with a change at or in association with a network node. For example, network node 305 may operate (for example, under control of radio map logic 306) to obtain (for example, measure, monitor, compute, derive, etc. ) updated network node information, report updated network node information, or a combination thereof in accordance with one or more periodicities, triggers, thresholds, etc. of the location-specific radio statistic information control. According to some examples, a network node may provide network node configuration information to routing system 325 as a change in operating status of a network node (for example, the reporting network node or a neighboring network node goes offline or comes back on line) is detected or occurs to facilitating updating of the database of network nodes. A network node may, for example, provide a network node configuration message, indicating an operating status of the network node as offline, to routing system 325 prior to a process to remove the network node from operational status is initiated. According to some examples, routing system 325 may nevertheless operate to update an operating status of a network node as offline (for example, to remove the network node from an active list of the database of network nodes) if network node configuration information or other signaling has not been provided by the network node or otherwise obtained for the network node in a period of time (for example, a preconfigured period of time, such as 1 day) .
[0107] In operation according to the example of FIG. 4, UE 315 obtains (for example, under control of radio map logic 316) road segment ID information, such as may be utilized with respect to associating aspects of radio map information with corresponding roadway areas according to some aspects. UE 315 of the illustrated example receives or otherwise obtains road segment ID information in communication 431 (for example, one or more messages of road segment ID message (s) 394) transmitted or otherwise provided by network node 305. Communication 431 may, for example, include road segment ID information for road segments of the region in which UE 315 is operating, a route being traveled by a vehicle of or associated with UE 315, for road segments of one or more roadways for which communication services are provided by network node 305, etc. In accordance with some examples, road segment ID information may be provided to UE 315 in batch, such as upon entering a particular area, upon initiating communication with network node 305, upon powering on, etc. In operation according to some examples, network nodes of wireless communications system 300 may signal (for example, via communication 431) UE 315 road segment ID information for a current, next, etc. road segment in real-time, such as while UE 315 travels a route or otherwise operates in association with a roadway for which communication services are provided by network node 305. UE 315 may additionally or alternatively compute road segment ID information, such as based on a GNSS signal (for example, in combination with a routing map downloaded through from routing system 325) . In accordance with some examples, road segment ID information may be computed using zone ID information, such as may be present in 3GPP packets, in combination with GNSS information, routing map data, or a combination thereof
[0108] According to some examples, a roadway may be segmented into one or more selected segment lengths and road segment ID information may be provided for each such road segment. FIG. 5A is a diagram illustrating an example of road segment ID information providing a one-to-one mapping between a road segment ID and corresponding road segment for segments of one or more roadways according to one or more aspects. In the example of FIG. 5A, roadway 500 is segmented along its length (for example, road segments in the range of 1m to 100m) providing road segments I95X1, I95X2, I95X3, I95X4, I95X5, and I95X6. Road segment ID information 511, 512, 513, 514, 515, and 516 is provided with respect to road segments I95X1, I95X2, I95X3, I95X4, I95X5, and I95X6 of roadway 500 of the illustrated example. The granularity of the road segments each ID represents may, for example, be pre-configured according to some aspects. Road segments corresponding to road segment ID information of aspects of the disclosure excludes the areas outside the boundaries of the roads. Accordingly, a relatively small number of bits (for example, fewer than 12 bits) may be used for the road segment ID information with respect to a region of some examples or, alternatively, the granularity of the road segments may be higher while maintaining a practicable number of bits (for example, 12 bits) used for the road segment ID information.
[0109] As shown in the example of FIG. 5A, a roadway of some examples may not only be segmented along its length, but the segmentation of a roadway may include segmentation of its width (for example, to provide different, individual segments for each driving lane of a segmented roadway portion) . Roadway 500, for example, includes lane 1 and lane 2. Road segment ID information 511, 512, 513, 514, 515, and 516 is provided with respect to road segments I95X1, I95X2, I95X3, I95X4, I95X5, and I95X6 of roadway 500. Road segment ID information 511, 513, and 515 is provided with respect to road segments I95X1, I95X3, and I95X5 of lane 1 of roadway 500 and road segment ID information 512, 514, and 516 is provided with respect to road segments I95X2, I95X4, and I95X6 of roadway 500. As should be appreciated from the foregoing, the road segment ID information of some examples may strictly distinguish lanes.
[0110] According to some aspects, roadways are segmented uniformly (for example, road segments of uniform or substantially uniform roadway length) . This is in contrast to segmentation provided using zone IDs in which a given area is divided into regions of equal size. FIG. 5B is a diagram illustrating an example of zone ID information for an area divided into zones according to one or more aspects. In the example of FIG. 5B, zone ID information 521 and 522 is provided with respect to zones zoneX1 and zoneX2. As illustrated in FIG. 5B, the zones are not uniform along the roads where the road is not straight or otherwise where the road direction does not align with the orientation of the zone. Moreover, the zones extend outside the boundaries of a particular roadway portion, and may encompass multiple roadways or portions of a roadways That is, zone ID information does not provide for uniform segmentation of roadways and does not support a one-to-one mapping between zone IDs and road segments.
[0111] Road segment ID information of examples above is configured to facilitate generating, updating, or otherwise maintaining roadway radio maps with respect to one or more regions, such as to support predictable and robust wireless communications, according to some aspects of the disclosure. For example, road segment ID information (for example, used in place of or in combination with GNSS derived information) may facilitate identification (for example, by radio map logic 316 of UE 315, radio map logic 306 of network node 305, radio map logic 326 of routing system 325, or a combination thereof) of which roadway, or even lane, UE 315 is operating on or with respect to. Such roadway identification may be particularly useful in situations where two roads are close to each other, or one is on top of another. According to some aspects, efficient processing of radio map information by systems such as routing system 325 may be enabled through the use of radio map information associated with corresponding roadway areas having uniform division of road segments indicated by road segment ID information of some examples.
[0112] Road segment ID information of some examples may be efficiently communicated (for example, as one or more messages of road segment ID message (s) 394, road segment ID message (s) 384, etc. ) in association with a vehicle of or associated with UE 315 traveling the corresponding roadway. For example, road segment ID information may be configured such that an increment of 1 bit is sent in association with UE 315 traversing a next road segment.
[0113] In operation according to the example illustrated in FIG. 4, UE 315 obtains (for example, under control of radio map logic 316) location-specific radio statistic information control, such as may be utilized with respect to controlling aspects of obtaining (for example, measuring, monitoring, computing, deriving, etc. ) location-specific radio statistic information of the radio map information. UE 315 of the illustrated example receives or otherwise obtains location-specific radio statistic information control signaling in communication 441 (for example, one or more messages of location-specific radio statistics message (s) 392) transmitted or otherwise provided by network node 305. Communication 441 may, for example, include information with respect to location-specific radio statistic information to be obtained / reported, periodicity information for obtaining / reporting location-specific radio statistic information, one or more triggers for obtaining / reporting location-specific radio statistic information, one or more thresholds for obtaining / reporting location-specific radio statistic information, etc., such as may correspond to one or more aspects of the radio map information control obtained by network node 305 from routing system 325.
[0114] According to the example of FIG. 4, network node 305 obtains (for example, under control of radio map logic 306) location-specific radio statistic information of the radio map information. For example, network node 305 of the illustrated example receives or otherwise obtains location-specific radio statistic information in communication 442 (for example, one or more messages of location-specific radio statistics message (s) 392) transmitted or otherwise provided by UE 315. In operation according to some aspects, network node 305 obtains location-specific radio statistic information associated with one vehicle once when that vehicle passes through an area for which communication services are provided by the network node. Communication 442 of some examples may include location-specific radio statistic information comprising wireless communication per-user uplink rate information, wireless communication per-user downlink rate information, wireless communication reliability information, wireless communication packet latency information, wireless communication RSSI information for each transmit-receive antenna pair, rate variation, RSSI variation, vehicle categorization information corresponding to one or more capabilities of a vehicle associated with the location-specific radio statistic information, etc. for one or more locations on at least one roadway. According to some examples, location-specific radio statistic information includes information with respect to include the number of transmit antennas, the number of receive antennas, when the vehicle of or associated with UE 315 is built, the vehicle / device model, the RF chain used, etc. Radio statistic information of communication 442 may comprise raw data, such as in a form as obtained by UE 315. Additionally or alternatively, radio statistic information of communication 442 may comprise processed or partially processed data, such as in a form provided by data computation, aggregation, compilation, etc. operation of radio map logic 316 of a UE.
[0115] According to some examples, location-specific radio statistic information of communication 442 may comprise statistic information on a road segment by road segment basis. Accordingly, road segment information (for example, road segment ID) for a location associated with respective location-specific radio statistic information may be provided in, or in association with, communication 442 (for example, included in one or more messages of location-specific radio statistics message (s) 392, one or more messages of road segment ID message (s) 394, or a combination thereof) . Additional or alternative location information (for example, GNSS location) associated with respective location-specific radio statistic information may be provided in, or in association with, communication 442 (for example, included in one or more messages of location-specific radio statistics message (s) 392) .
[0116] Location-specific radio statistic information of communication 442, the associated road segment IDs, or a combination thereof of may be reported to network nodes (for example, network node 305) according to some examples in one or more network layer messages (for example, sidelink control information message, such as SCI-2, media access control (MAC) header, MAC-control element (MAC-CE) message, radio resource control (RRC) message, etc. ) , with or without accompanying radio map information (for example, location-specific radio statistic information) . Additionally or alternatively, location-specific radio statistic information, associated road segment IDs, or a combination thereof, may be reported to network nodes in an upper layer message or an application layer message according to some examples.
[0117] Location-specific radio statistic information of communication 442 may, for example, be provided in accordance with aspects of location-specific radio statistic information control obtained by UE 315 (for example, via communication 441) . According to some examples, UE 315 may operate (for example, under control of radio map logic 316) to obtain (for example, measure, monitor, compute, derive, etc. ) location-specific radio statistic information, report location-specific radio statistic information, or a combination thereof in accordance with one or more periodicities, triggers, thresholds, etc. of the location-specific radio statistic information control. Additionally or alternatively, UE 315 may operate to obtain location-specific radio statistic information, report location-specific radio statistic information, or a combination thereof in response to a reporting request (for example, trigger message) , such as may be transmitted by a network node (for example, network node 305) .
[0118] In operation according to the example illustrated in FIG. 4, routing system 325 obtains (for example, under control of radio map logic 326) location-specific radio statistic information of the radio map information. For example, routing system 325 of the illustrated example receives or otherwise obtains location-specific radio statistic information in communication 443 (for example, one or more messages of location-specific radio statistics message (s) 382) transmitted or otherwise provided by network node 305. Such location-specific radio statistic information of some examples may be provided from network node 305 to routing system 325 to be used in route computation.
[0119] Communication 443 may, for example, include location-specific radio statistic information forwarded by network node 305 from one or more UEs, such as may comprise wireless communication per-user uplink rate information, wireless communication per-user downlink rate information, wireless communication reliability information, wireless communication packet latency information, wireless communication RSSI information for each transmit-receive antenna pair, rate variation, RSSI variation, vehicle categorization information corresponding to one or more capabilities of a vehicle associated with the location-specific radio statistic information, etc. for one or more locations on at least one roadway. According to some examples, location-specific radio statistic information includes information with respect to include the number of transmit antennas, the number of receive antennas, when the vehicle of or associated with the UE is built, the vehicle / device model, the RF chain used, etc. Location-specific radio statistic information of communication 443 may comprise raw data, such as in a form as obtained by network node 305. Additionally or alternatively, location-specific radio statistic information of communication 443 may comprise processed or partially processed data, such as in a form provided by data computation, aggregation, compilation, etc. operation of radio map logic 316 of a UE, radio map logic 306 of network node 305, or a combination thereof.
