Numerous other aspects are provided.

Description

Technical Field

[0001] In summary, the technical aspects described below relate to wireless communication, and specifically to techniques and apparatus for congestion control based at least in part on the motion state of a user equipment (UE). Some of the techniques and apparatus described herein implement and provide wireless communication devices and systems configured to improve spectral efficiency, capacity, and data rates. 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 can utilize multiple access technologies that enable communication with multiple users by sharing available system resources (e.g., bandwidth, transmit power, etc.). Examples of these 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, Time Division Synchronous Code Division Multiple Access (TD-SCDMA) systems, and Long Term Evolution (LTE). LTE / LTE-Advanced is a set of enhancements to the Universal Mobile Telecommunications System (UMTS) mobile standard released by the 3rd Generation Partnership Project (3GPP).

[0003] A wireless communication network may include multiple base stations (BSs) supporting communication with multiple user equipments (UEs). UEs can communicate with base stations (BSs) via downlinks and uplinks. A downlink (or forward link) refers to the communication link from the BS to the UE, while an uplink (or reverse link) refers to the communication link from the UE to the BS. A BS may be referred to as a Node B, gNB, Access Point (AP), Radio Headend, Transmit / Receive Point (TRP), New Radio (NR) BS, 5G Node B, etc.

[0004] Multiple access technologies have been adopted in various telecommunications standards. Wireless communication standards provide common protocols that enable different devices (e.g., user equipment) to communicate at the city, country, region, or even global level. New Radio (NR) (also known as 5G) is a set of enhancements to the LTE mobile standard released by the 3rd Generation Partnership Project (3GPP). With the continued increase in demand for mobile broadband access, further improvements to LTE and NR technologies are needed. These improvements can be made by other multiple access technologies and telecommunications standards that use these technologies. Summary of the Invention

[0005] The following summarizes some aspects of this disclosure to provide a basic understanding of the techniques discussed. This summary is not an exhaustive overview of all the features considered in this disclosure, nor is it intended to identify key or essential elements of all aspects of this disclosure, nor to describe the scope of any or all aspects of this disclosure. The purpose of this summary is to present some concepts of one or more aspects of this disclosure in summary form as a prelude to the more detailed description that follows.

[0006] UEs can perform periodic transmissions for various purposes. For example, in a cellular vehicle-to-everything (CV2X) deployment, a UE associated with a vehicle can periodically send messages, such as Basic Security Messages (BSMs), to notify other CV2X-enabled vehicles of the static and dynamic status of the UE or the vehicle associated with the UE. As used herein, a CV2X-enabled vehicle can refer to a vehicle associated with a UE capable of performing CV2X communication.

[0007] In certain situations, dense traffic scenarios may occur. For example, a congested street with many CV2X-enabled vehicles may cause a large number of messages to be sent, leading to over-the-air (OTA) congestion on the communication channels used by CV2X-enabled vehicles. Therefore, congestion control is a crucial component of CV2X system design to reduce message collisions and prevent the loss of safety-critical messages. Since CV2X communication does not use a central scheduling entity, such as a base station, distributed congestion control (DCC) techniques can be used.

[0008] Different CV2X-enabled vehicles can be associated with different operating conditions. For example, one CV2X-enabled vehicle might travel faster, be more maneuverable, or navigate traffic more dangerously than another. Periodic messages sent between two CV2X-enabled vehicles (e.g., BSMs) can convey speed, location, and direction information. However, using the same parameters for periodic transmissions between the two vehicles may not be optimal when they are operating under different conditions. For example, on a straight road, a vehicle traveling at high speed or high acceleration poses a greater risk than one traveling at a slow or constant speed. If a vehicle traveling at high speed or high acceleration provides periodic messages, such as BSM messages, at the same interval as a vehicle traveling at low speed or low acceleration, other vehicles may receive less granular information about the operating parameters of the vehicle traveling at high speed or high acceleration (e.g., for a vehicle traveling at 100 m / s, 10 messages per second will only provide an update every 10 m, while for a vehicle traveling at 25 m / s, 10 messages per second will provide an update every 2.5 m).

[0009] Some of the techniques and apparatus described herein provide adjustments to the inter-transmission time (ITT) for messages periodically transmitted by the UE, based at least in part on the UE's motion state. The UE can determine the ITT based at least in part on channel conditions such as vehicle congestion and channel congestion. UEs associated with higher motion states (e.g., faster speed, higher acceleration, faster rotation speed, etc.) can have their ITT adjusted to a relatively shorter value than UEs associated with lower motion states. Therefore, UEs associated with higher motion states can provide messages more frequently than UEs associated with lower motion states, thereby improving security. Furthermore, adjusting the ITT can reduce channel congestion in congested deployment scenarios compared to the inflexible approach of using the same parameters for periodic message transmission across all vehicles.

[0010] In some aspects, a wireless communication method performed by a user equipment (UE) may include: determining inter-transmission time values ​​for a series of transmissions to be performed by the UE; adjusting the inter-transmission time values ​​based at least in part on a motion state associated with the UE; and performing the series of transmissions according to the adjusted inter-transmission time values.

[0011] In some aspects, a UE for wireless communication may include a memory and one or more processors operatively coupled to the memory. The memory and the one or more processors may be configured to: determine inter-transmission time values ​​for a series of transmissions to be performed by the UE; adjust the inter-transmission time values ​​at least in part based on a motion state associated with the UE; and perform the series of transmissions according to the adjusted inter-transmission time values.

[0012] In some aspects, a non-transitory computer-readable medium may store one or more instructions for wireless communication. When executed by one or more processors of a UE, the one or more instructions may cause the processors to: determine inter-transmission time values ​​for a series of transmissions to be performed by the UE; adjust the inter-transmission time values ​​based at least in part on a motion state associated with the UE; and perform the series of transmissions according to the adjusted inter-transmission time values.

[0013] In some aspects, an apparatus for wireless communication may include: a unit for determining inter-transmission time values ​​for a series of transmissions to be performed by the apparatus; a unit for adjusting the inter-transmission time values ​​based at least in part on a motion state associated with the apparatus; and a unit for performing the series of transmissions according to the adjusted inter-transmission time values.

[0014] The aspects generally include methods, apparatus, systems, computer program products, non-transitory computer-readable media, user equipment, base stations, wireless communication equipment and / or processing systems as described herein with reference to the accompanying drawings and description.

[0022] The various aspects of this disclosure are described more fully below with reference to the accompanying drawings. However, this disclosure may be implemented in many different forms and should not be construed as being limited to any particular structure or function given throughout this disclosure. Rather, these aspects are provided so that this disclosure will be thorough and complete, and will fully convey the scope of this disclosure to those skilled in the art. Based on the teachings herein, those skilled in the art will understand that the scope of this disclosure is intended to cover any aspect of the disclosure herein, whether implemented independently of or in combination with any other aspect of this disclosure. For example, any number of aspects set forth herein may be used to implement an apparatus or method. Furthermore, the scope of this application is intended to cover such apparatus or methods practiced using structures, functions, or structures and functions other than or different from the aspects of the disclosure given herein. It should be understood that any aspect of the disclosure herein may be embodied by one or more elements of the claims.

[0023] Several aspects of a telecommunications system will now be presented with reference to various devices and technologies. These devices and technologies will be described in detail below and illustrated in the accompanying drawings by various blocks, modules, components, circuits, steps, processes, algorithms, etc. (collectively, “elements” or “features”). These elements can be implemented using hardware, software, or a combination thereof. Whether these elements are implemented as hardware or software depends on the specific application and the design constraints imposed on the overall system.

[0024] While the various aspects may be described herein using terms commonly associated with 3G and / or 4G wireless technologies, the aspects of this disclosure may be applied to other generation-based communication systems, such as 5G and later versions, including NR technology.

[0025] While aspects and embodiments have been described in this application by way of example, those skilled in the art will understand that additional implementations and use cases may arise in many different arrangements and scenarios. The innovations described herein can be implemented across many different platform types, devices, systems, shapes, sizes, and package arrangements. For example, embodiments and / or uses may occur via integrated chip embodiments and / or 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 particular use case or application, broad applicability of the described innovations is possible. Implementations may range from chip-level or modular components to non-modular, non-chip-level implementations, and further involve aggregated, distributed, or original equipment manufacturer (OEM) devices or systems incorporating one or more aspects of the described innovations. In some practical settings, devices incorporating the described aspects and features may also necessarily include additional components and features for the implementation and embodiment of the claimed and described embodiments. For example, the transmission and reception of wireless signals necessarily involve multiple components for analog and digital purposes (e.g., hardware components including one or more antennas, radio frequency (RF) chains, power amplifiers, modulators, buffers, processors, interleavers, adders / converters, etc.). The aim is that the innovations described herein can be implemented in a variety of devices, chip-level components, systems, distributed arrangements, end-user equipment, etc., with varying sizes, shapes, and constructions.

[0026] Figure 1 This diagram illustrates a wireless network 100 in which aspects of this disclosure may be implemented. The wireless network 100 may be an LTE network or some other wireless network, such as a 5G or NR network. The wireless network 100 may include multiple BS 110s (shown as BS 110a, BS 110b, BS 110c, and BS 110d) and other network entities. A BS is an entity that communicates with a user equipment (UE) and may also be referred to as a base station, NR BS, Node B, gNB, 5G Node B (NB), access point, Transmit / Receive Point (TRP), etc. Each BS may provide communication coverage for a specific area (e.g., a fixed or changing geographical area). In some scenarios, BS 110 may be stationary or non-stationary. In some non-stationary scenarios, mobile BS 110 may move at varying speeds, directions, and / or altitudes. In 3GPP, the term "cell" may refer to the coverage area of ​​BS 110 and / or the BS subsystem serving that coverage area, depending on the context in which the term is used.

[0027] A BS can provide communication coverage for macrocells, picocells, femtocells, and / or another type of cell. A macrocell can cover a relatively large geographic area (e.g., a radius of several kilometers) and allow unrestricted access for UEs with service subscriptions. Additionally or alternatively, the BS can support access to unlicensed RF bands (e.g., Wi-Fi bands, etc.). A picocell can cover a relatively small geographic area and allow unrestricted access for UEs with service subscriptions. A femtocell can cover a relatively small geographic area (e.g., a home) and allow restricted access for UEs associated with that femtocell (e.g., UEs in a Closed Subscriber Group (CSG)). A BS for a macrocell may be referred to as a macro BS. A BS for a picocell may be referred to as a pico BS. A BS for a femtocell may be referred to as a femto BS or a home BS. Figure 1 In the example shown, BS 110a can be a macro BS of macro cell 102a; BS 110b can be a pico BS of pico cell 102b; and BS 110c can be a femto BS of femto cell 102c. A BS can support one or more (e.g., three) cells. The terms “eNB”, “base station”, “NR BS”, “gNB”, “TRP”, “AP”, “Node B”, “5G NB”, and “cell” are used interchangeably in this document.

[0028] In some aspects, the cell may not be stationary, and the geographical area of ​​the cell may move depending on the location of the mobile BS. In some aspects, BSs can be interconnected to each other and / or one or more other BSs or network nodes (not shown) in the wireless network 100 using any suitable transport network via various types of backhaul interfaces (such as direct physical connections, virtual networks, etc.). In other scenarios, BSs can be implemented using software-defined networking (SDN) or via network functions virtualization (NFV).

[0029] The wireless network 100 may also include a relay station. A relay station is an entity that can receive data transmissions from an uplink station (e.g., a BS or a UE) and transmit data transmissions to a downlink station (e.g., a UE or a BS). A relay station can also be a UE that can relay transmissions for other UEs. Figure 1 In the example shown, relay station 110d can communicate with macro BS 110a and UE 120d to facilitate communication between BS 110a and UE 120d. A relay station can also be referred to as a relay BS, relay base station, repeater, etc.

[0030] Wireless network 100 can be a heterogeneous network comprising different types of Base Stations (BSs) (e.g., macro BSs, pico BSs, femto BSs, relay BSs, etc.). These different types of BSs can have different transmit power levels, different coverage areas, and different effects on interference in wireless network 100. For example, macro BSs can have higher transmit power levels (e.g., 5 to 40 watts), while pico BSs, femto BSs, and relay BSs can have lower transmit power levels (e.g., 0.1 to 2 watts).

[0031] Network controller 130 can be coupled to a group of base stations (BSs) and can provide coordination and control for these BSs. Network controller 130 can communicate with the BSs via backhaul. BSs can also communicate with each other, for example, directly or indirectly via wireless or wired backhaul.

[0032] UE 120 (e.g., 120a, 120b, 120c) may be distributed throughout the wireless network 100, and each UE may be fixed or mobile. UE may also be referred to as a terminal, mobile station, user unit, station, etc. UE may be a cellular phone (e.g., a smartphone), personal digital assistant (PDA), wireless modem, wireless communication device, handheld device, laptop computer, cordless phone, wireless local loop (WLL) station, tablet computer, camera, gaming device, netbook, smartbook, ultrabook, medical device or equipment, biometric sensor / device, wearable device (smartwatch, smart clothing, smart glasses, smart wristband, smart jewelry (e.g., smart ring, smart bracelet)), entertainment device (e.g., music or video device, or satellite radio), vehicle component or sensor, smart meter / sensor, industrial manufacturing equipment, robot, drone, implantable device, augmented reality device, GPS device, or any other suitable device configured to communicate via wireless or wired media.

[0033] Some UEs can be considered Machine-Type Communication (MTC) or Evolved or Enhanced Machine-Type Communication (eMTC) UEs. MTC and eMTC UEs include, for example, robots, drones, remote devices, sensors, meters, monitors, location tags, etc., capable of communicating with a base station, another device (e.g., a remote device), or some other entity. Wireless nodes can provide, for example, connectivity to or from a network (e.g., a wide area network such as the Internet or cellular networks) via wired or wireless communication links. Some UEs can be considered Internet of Things (IoT) devices, and / or can be implemented as NB-IoT (Narrowband Internet of Things) devices. Some UEs can be considered Customer Premises Equipment (CPE). UE 120 can be included within a housing containing components of UE 120, such as processor components, memory components, etc. These components can be integrated in various combinations and / or can be independent distributed components, taking into account design constraints and / or operational preferences.

[0034] In summary, any number of wireless networks can be deployed within a given geographical area. Each wireless network can support a specific RAT and can operate on one or more frequencies. A RAT can also be referred to as a radio technology, air interface, etc. A frequency can also be referred to as a carrier, frequency channel, etc. Each frequency can support a single RAT within a given geographical area to avoid interference between wireless networks using different RATs. In some cases, NR or 5G RAT networks can be deployed.

[0035] In some aspects, two or more UEs 120 (e.g., shown as UE 120a and UE 120e) can communicate directly using one or more sidelink channels (e.g., without using base station 110 as an intermediary device). For example, UEs 120 can communicate using peer-to-peer (P2P) communication, device-to-device (D2D) communication, vehicle-to-all (V2X) protocols (e.g., which may include vehicle-to-vehicle (V2V) protocols, vehicle-to-infrastructure (V2I) protocols, etc.), mesh networks, etc. In this case, UEs 120 can perform scheduling operations, resource selection operations, and / or other operations described elsewhere herein that are performed by base station 110. In these deployment scenarios, the UE performing the scheduling operations may include or perform base station-like functions.

[0036] As mentioned above, providing Figure 1 This is just an example. Other examples may differ from those for [specific purposes]. Figure 1 The example described.

[0037] Figure 2 A block diagram of a design 200 for base station 110 and UE 120 is shown. Base station 110 and UE 120 can be... Figure 1A base station and a UE are provided. The base station 110 may be equipped with T antennas 234a to 234t, and the UE 120 may be equipped with R antennas 252a to 452r, where typically T ≥ 1 and R ≥ 1. The T and R antennas may be configured with multiple antenna elements, which are formed in an array for possible MIMO or massive MIMO deployments in millimeter-wave (mmWave or mmW) communication systems.

[0038] At base station 110, transmit processor 220 can perform a number of communication-related functions. For example, transmit processor 220 can receive data for one or more UEs from data source 212, select one or more modulation and coding schemes (MCS) for each UE based at least in part on a Channel Quality Indicator (CQI) received from each UE, process the data for each UE (e.g., coding and modulation) based at least in part on the MCS selected for each UE, and provide data symbols for all UEs. Transmit processor 220 can also process system information (e.g., semi-static resource allocation information (SRPI), etc.) and control information (e.g., CQI requests, grants, upper-layer signaling, etc.), and provide overhead symbols and control symbols. Transmit processor 220 can also generate reference symbols for reference signals (e.g., cell-specific reference signals (CRS)) and synchronization signals (e.g., primary synchronization signal (PSS) and secondary synchronization signal (SSS)). If applicable, the transmit (TX) multiple-input multiple-output (MIMO) processor 230 can perform spatial processing (e.g., precoding) on ​​data symbols, control symbols, overhead symbols, and / or reference symbols, and can provide T output symbol streams to T modulators (MODs) 232a to 232t. Each modulator 232 can process its respective output symbol stream (e.g., for orthogonal frequency division multiplexing (OFDM), etc.) to obtain an output sample stream. Each modulator 232 can further process (e.g., convert to analog, amplify, filter, and upconvert) the output sample stream to obtain a downlink signal. The T downlink signals from modulators 232a to 232t can be transmitted separately via T antennas 234a to 234t. Position coding can be used to generate synchronization signals to transmit additional information, according to various aspects described in more detail below.

[0039] At UE 120, antennas 252a to 252r can receive downlink RF signals. These downlink RF signals can be received from and / or transmitted by one or more base stations 110. These signals can be provided to demodulators (DEMODs) 254a to 254r, respectively. Each demodulator 254 can modulate (e.g., filter, amplify, down-convert, and digitize) the received signal to obtain an input sample. Each demodulator 254 can further process the input sample (e.g., for OFDM, etc.) to obtain received symbols. A MIMO detector 256 can obtain the received symbols from all R demodulators 254a to 254r, perform MIMO detection on the received symbols if applicable, and provide the detected symbols. A receive processor 258 can process (e.g., demodulate and decode) the detected symbols, provide decoded data for UE 120 to data sink 260, and provide decoded control and system information to controller / processor 280. The channel processor can determine the Reference Received Power (RSRP), Received Signal Strength Indicator (RSSI), Reference Received Quality (RSRQ), Channel Quality Indicator (CQI), and so on. In some aspects, one or more components of the UE 120 may be included in a housing.

[0040] For uplink communication, UE 120 can transmit control information and / or data to another device, such as one or more base stations 110. For example, at UE 120, transmit processor 264 can receive and process data from data source 262 and control information (e.g., reports including RSRP, RSSI, RSRQ, CQI, etc.) from controller / processor 280. Transmit processor 264 can also generate reference symbols for one or more reference signals. Symbols from transmit processor 264 can be pre-encoded by TX MIMO processor 266, further processed by modulators 254a to 254r (e.g., for DFT-s-OFDM, CP-OFDM, etc.), and transmitted to base station 110, if applicable. At base station 110, uplink signals from UE 120 and other UEs can be received by antenna 234, processed by demodulator 232, detected by MIMO detector 236 if applicable, and further processed by receiver processor 238 to obtain decoded data and control information transmitted by UE 120. Receiver processor 238 can provide decoded data to data sink 239 and decoded control information to controller / processor 240. Base station 110 may include communication unit 244 and communicate with network controller 130 via communication unit 244. Network controller 130 may include communication unit 294, controller / processor 290, and memory 292.

[0041] As described in more detail elsewhere in this document, the controller / processor 240 of base station 110, the controller / processor 280 of UE 120, and / or Figure 2 Any other components may perform one or more techniques associated with congestion control, at least in part based on the motion state of the UE. For example, the controller / processor 240 of base station 110, the controller / processor 280 of UE 120, and / or Figure 2 Any other component can perform or direct, for example Figure 5 The process 500 operates and / or other processes as described herein. Memory 242 and 282 may store data and program code for base station 110 and UE 120, respectively. Scheduler 246 may schedule the UE for data transmission on the downlink and / or uplink.

[0042] In some aspects, UE 120 may include various units or components for implementing communication functions. For example, various units may include: units for determining inter-transmission time values ​​for a series of transmissions to be performed by UE 120; units for adjusting the inter-transmission time values ​​based at least in part on the motion state associated with UE 120; units for performing a series of transmissions according to the adjusted inter-transmission time values; units for adjusting the inter-transmission time based at least in part on one or more threshold speed values; units for adjusting the inter-transmission time based at least in part on the direction associated with a turn performed by a vehicle associated with UE 120; and so on.

[0043] In some aspects, UE 120 may include various structural components for performing the functions of various units. For example, the structural components for performing the functions of these units may include combinations of... Figure 2 One or more components of the described UE 120, such as antenna 252, DEMOD 254, MOD 254, MIMO detector 256, receive processor 258, transmit processor 264, TX MIMO processor 266, controller / processor 280, etc.

[0044] As mentioned above, providing Figure 2 This is just an example. Other examples may differ from those for [specific purposes]. Figure 2 The example described.

[0045] Figure 3This is a diagram illustrating example 300, which adjusts the inter-transmission time based at least in part on the motion state of the UE according to various aspects of this disclosure. As shown, example 300 includes UE 120-1 and UE 120-2. In some aspects, UE 120-1 and UE 120-2 may be associated with a CV2X deployment (e.g., may be associated with or installed in a vehicle with CV2X capability), although the techniques described herein can be used in other types of deployments besides CV2X.

[0046] As shown by reference numeral 310 in the attached figure, UE 120-1 can determine a series of basic ITTs for transmission. The basic ITT, also referred to herein as the initial ITT, can refer to an ITT value that has not yet been adjusted at least partially based on the motion state of UE 120-1, or an ITT value determined at least partially based on channel conditions rather than the motion state of UE 120-1. In some aspects, UE 120-1 can determine the basic ITT at least partially based on channel conditions associated with UE 120-1, such as channel busy rate (CBR), reference signal determination, signal-to-noise ratio, transmitter density, etc.

[0047] In some respects, UE 120-1 may determine the basic ITT at least in part based on a vehicle density threshold associated with UE 120-1. For example, standards (e.g., SAE 3161, which defines onboard system requirements for LTE vehicle-to-vehicle (V2V) secure communication) may define effective application-layer DCC technology. This technology may be based at least in part on the traffic environment surrounding UE 120-1 within a threshold range and time. Parameters used for DCC technology include CBR, vehicle density, etc. The standard may indicate that the ITT is determined at least in part based on vehicle density. For example, if the vehicle density meets the threshold, UE 120-1 may increase the ITT. In some respects, UE 120-1 may determine vehicle density at least in part based on messages such as BSM received from other vehicles or other UE 120s.

[0048] In some respects, UE 120-1 can determine one or more parameters for a range of transmissions, such as transmission range (e.g., radiated power adjustment based at least in part on CBR). For example, if the CBR of UE 120-1 meets a threshold, UE 120-1 can reduce the radiated power of UE 120-1.

[0049] In some respects, UE 120-1 may determine the basic ITT value based at least in part on a vehicle density threshold. For example, UE 120-1 may use the following Formula 1 to determine the basic ITT value (ITT). basic ):

[0050]

[0051] In Formula 1, ITT ref and ITT max The possible range of ITT values ​​is defined. The value vn is the number of vehicles observed within the threshold range of UE 120-1. Th1 and Th2 are the thresholds for vehicle density.

[0052] As shown in reference numeral 320, UE 120-1 may adjust the basic ITT (e.g., initial ITT) at least in part based on the motion state of UE 120-1. For example, UE 120-1 may increase or decrease the ITT at least in part based on the motion state of UE 120-1. Figure 4 An example is shown of adjusting the basic ITT of the first and second vehicles based at least in part on the corresponding motion states of the first and second vehicles. UE 120-1 can receive information identifying the motion state from the systems of the respective vehicles. Additionally or alternatively, UE 120-1 can determine the information identifying the motion state (e.g., using sensors of UE 120-1).

[0053] In some respects, UE 120-1 can adjust the basic ITT at least partially based on vehicle speed. For example, UE 120-1 can increase the ITT of low-speed vehicles (resulting in lower-frequency transmissions) and decrease the ITT of high-speed vehicles. Therefore, high-speed vehicles can provide more frequent updates. More frequent updates from high-speed vehicles can improve vehicle safety. Furthermore, low-speed vehicles may provide fewer updates compared to high-speed vehicles. Lower update frequencies from low-speed vehicles may reduce channel congestion.

[0054] In some respects, UE 120-1 can adjust the basic ITT at least in part based on the vehicle's direction, such as the direction of a turn. For example, UE 120-1 can increase the ITT of vehicles turning in a first direction or continuing to travel in a straight line (resulting in less frequent transmissions) and decrease the ITT of vehicles turning in a second direction. Therefore, vehicles turning in a higher-risk direction, such as turning left through traffic, can receive more frequent updates. This can improve vehicle safety. Furthermore, vehicles performing lower-risk maneuvers can receive fewer updates, which can reduce channel congestion.

[0055] In some respects, UE 120-1 can adjust the basic ITT at least in part based on factors such as the vehicle's rotational speed associated with sharp turns. For example, UE 120-1 can increase the ITT for vehicles performing less sharp turns (resulting in less frequent transmissions) and decrease the ITT for vehicles performing sharper turns. Thus, vehicles performing higher-risk maneuvers can receive more frequent updates. This can improve vehicle safety. Furthermore, vehicles performing lower-risk maneuvers can receive fewer updates, which can reduce channel congestion.

[0056] In some respects, UE 120-1 can adjust the basic ITT based at least in part on vehicle acceleration (e.g., linear acceleration). For example, UE 120-1 can increase the ITT of vehicles associated with smaller acceleration amplitudes (resulting in less frequent transmissions) and decrease the ITT of vehicles associated with larger acceleration amplitudes. Therefore, vehicles accelerating more aggressively can provide more frequent updates. This can improve vehicle safety. Furthermore, vehicles accelerating less or not accelerating at all can provide less frequent updates, which can reduce channel congestion.

[0057] In some respects, UE 120-1 may use a combination of two or more of the factors described above to determine the adjustment of the basic ITT. For example, UE 120-1 may use an average ITT value, a minimum ITT value, etc., determined using a combination of two or more of the factors described above. In some respects, UE 120-1 may use one or more factors other than those described above, or factors that are alternatives to those described above, such as Quality of Service (QoS) information (e.g., for unicast or multicast scenarios), etc.

[0058] As shown by reference numeral 330 in the attached figure, UE 120-1 can perform a series of transmissions according to the adjusted ITT. For example, as shown by reference numeral 340 in the attached figure, UE 120-1 can perform a first transmission (TX), can wait for a period of time defined by the adjusted ITT, can perform a second TX, and so on. The transmissions can include any message. In some aspects, the transmissions can be BSM, etc.

[0059] In some respects, UE 120-1 can update the adjusted ITT. For example, UE 120-1 can update the adjusted ITT periodically (e.g., after a certain time length or a certain number of transmissions). As another example, UE 120-1 can update the adjusted ITT at least in part based on changes in the motion state of UE 120-1 (e.g., when the motion state of UE 120-1 changes by a threshold amount).

[0060] Therefore, DCC is provided for CV2X deployment based at least in part on the motion state of UE 120. This reduces channel congestion and improves security.

[0061] Although the techniques and apparatus described herein are primarily for adjusting ITT values, they can also be used to adjust other transmission parameters of the UE 120, such as radiated power, repetitive configuration, etc.

[0062] As mentioned above, providing Figure 3 As an example. Other examples may differ from those for... Figure 3 The example described.

[0063] Figure 4 This is a diagram illustrating another example 400 of adjusting inter-transmission time based at least in part on the motion state of the UE, according to various aspects of this disclosure. As shown, example 400 includes vehicles 405-1 and 405-2. Vehicle 405 is associated with a corresponding UE 120. In some aspects, vehicles 405-1 and 405-2 may be vehicles with CV2X functionality. Figure 4 In the associated description, references to UE 120 may refer to UE 120 associated with one or more of vehicles 405-1 and 405-2, depending on the context. In Example 400, the determination of the adjusted ITT value is based at least in part on the speed of vehicle 405 and / or UE 120.

[0064] As shown by reference numeral 410 in the attached figure, UE 120 can be configured with a set of parameters for determining the adjusted ITT value. For example, the parameters include Th1 and Th2 (in combination) with values ​​of 25 and 100. Figure 3 (More detailed description) ITT value of 100ms min ITT with a value of 600ms max And IT with a value of 150ms Tref Value. ITT ref The value can define a lower bound for the initial ITT value, while ITT min The value can define a lower limit for the adjusted ITT value. Furthermore, UE 120 is configured with speed thresholds (SpeedTh1 and SpeedTh2) for determining the adjustment of the initial ITT value, as described below.

[0065] In some aspects, UE 120 can be configured with a set of parameters. For example, the onboard unit of vehicle 405 and / or UE 120 can be configured with this set of parameters (e.g., at least in part based on application layer standards). In some aspects, UE 120 can be configured by a network (e.g., a roadside unit, a base station, etc.). In this case, the configuration can be at least in part based on service conditions associated with the network. In some aspects, UE 120 can determine this set of parameters. For example, UE 120 can determine the set of parameters at least in part based on service conditions, channel conditions, UE 120 capabilities, etc.

[0066] As shown by reference numeral 415 in the attached figure, UE 120 can determine the initial ITT value (ITT). initial Here, the initial ITT value is equal to ITT. ref This can be based, at least in part, on traffic conditions, channel conditions, vehicle density thresholds, etc.

[0067] As shown by reference numeral 420 in the attached figure, UE 120 can determine the final ITT value (e.g., ITTfinal). As shown, UE 120 can use Formula 2 to determine the final ITT value:

[0068] ITT final =max(min(ITT) adj ITT max ), ITT min ) Formula 2

[0069] In Formula 2, ITT final The lower limit is ITT min The upper limit is ITT. max ITT adj It is an adjusted ITT value determined at least in part based on the motion state. It is assumed that the adjusted ITT value does not exceed the ITT. min and ITT max The range between, then ITT adj It can be equal to ITT final If ITT adj Higher than ITT max Then ITT final equal to ITT max If ITT adj Below ITT min Then ITT final equal to ITT min .

[0070] As shown by reference numeral 425 in the attached figure, UE 120 may determine the adjusted ITT value based at least in part on a factor referred to herein as the speed factor. The speed factor may be based at least in part on the motion state of UE 120 or vehicle 405. Here, UE 120 uses Equation 3 to determine the ITT. adj :

[0071] ITT adj =ITT initial ×Speedfactor Formula 3

[0072] As indicated by reference numeral 430 in the attached figure, the velocity factor can be at least partially based on the conditions. The conditions are shown in Equation 4 below:

[0073] The ITTs of vehicles 405-1 and 405-2 respectively adj and ITT final The values ​​are determined by reference numerals 435 and 440. As shown by reference numeral 435, the speed factor of vehicle 405-1 can be ≈-0.33 (determined using formula 4), resulting in ITT. adj =150×(1-0.33)=100ms (determined using Formula 3) and thus results in an ITT of 100ms. final (Determined using Formula 2). As shown by reference numeral 440 in the attached diagram, the speed factor of vehicle 405-2 can be equal to 1, resulting in ITT. adj =150×(1)=150ms, therefore resulting in an ITT of 150ms. final .

[0074] Therefore, vehicle 405-1, associated with higher speed, sends messages more frequently than vehicle 405-2. This reduces congestion compared to using 100ms ITT for both vehicles, while providing the benefit of more frequent transmissions, thus improving the security of vehicle 405-1.

[0075] As another example ( Figure 4 (Not shown in the diagram), consider a scenario where a vehicle approaches an intersection without traffic lights. Assume the first vehicle proceeds straight through the intersection from the first direction, the second vehicle turns left from the second direction, and the third vehicle turns right from the third direction. In this case, the second vehicle turning left may pose a higher risk compared to the first vehicle not turning or the third vehicle turning right. Therefore, the technique described herein can adjust the ITT of the second vehicle to be lower than that of the first or third vehicle. As an example, UE 120 can combine Equation 2 above with Equations 5 and 6 below (reproduced here for clarity):

[0076] ITT final=max(min(ITT) adj ITT max ), ITT min )

[0077] Formula 2

[0078] ITT adj =ITT basic ×Turningfactor

[0079] Formula 5

[0080]

[0081] Formula 6

[0082] As shown in the figure, formulas 5 and 6 use a steering factor (e.g., the motion state of UE 120) to determine the adjusted ITT. Here, the steering factor is lowest for left turns, meaning that the ITT value for left-turning vehicles is the shortest. For example, UE 120 can determine the adjusted ITT value as follows:

[0083] First vehicle: Steering factor = 1; ITT adj =150×1=150ms; ITT final =150ms

[0084] Second vehicle: Steering factor = 0.6; ITT adj =150 × 0.6 = 90 ms; ITT final =100ms

[0085] Third vehicle: Steering factor = 0.8; ITT adj =150 × 0.8 = 120 ms; ITT final =120ms

[0086] Therefore, the second vehicle making a higher-risk left turn has a shorter ITT value compared to the first or third vehicle, thus improving the safety of all three vehicles. Furthermore, the first vehicle directly crossing the intersection has a longer ITT value compared to the second or third vehicle, thus reducing channel congestion.

[0087] In some aspects, UE 120 can adjust the inter-transmission time value to be equal to the time elapsed since the previous transmission in a series of transmissions, at least in part, based on a motion state meeting a threshold. For example, UE 120 can transmit a transmission in association with a motion state that meets a threshold. In some aspects, UE 120 can transmit the transmission immediately after the motion state meets the threshold. This allows other UEs or the vehicle of UE 120 that meets the threshold to be notified before the inter-transmission time value has elapsed, thereby improving security.

[0088] As mentioned above, providing Figure 4 As an example. Other examples may differ from those for... Figure 4 The example described.
