[0002] This patent application claims priority to U.S. Provisional Patent Application No. 63 / 042,410, filed June 22, 2020, entitled “APPLICATION BASED RANGE MANAGEMENT FOR CELLULAR VEHICLE-TO-ANYTHING COMMUNICATION,” and U.S. Non-Provisional Patent Application No. 17 / 304,313, filed June 17, 2021, entitled “APPLICATION BASED RANGE MANAGEMENT FOR CELLULAR VEHICLE-TO-ANYTHING COMMUNICATION,” the contents of which are expressly incorporated herein by reference. Technical Field

[0003] In summary, aspects of this disclosure relate to wireless communications, and specifically to technologies and apparatus for application-based range management of cellular vehicle-to-everything (V2X) communications. Background Technology

[0004] 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).

[0005] A wireless network may include multiple base stations (BSs) supporting communication for multiple user equipments (UEs). UEs can communicate with the BS via downlinks and uplinks. A "downlink" (or "forward link") refers to the communication link from the BS to the UE, while an "uplink" (or "backlink") refers to the communication link from the UE to the BS. As will be described in more detail herein, 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.

[0006] The aforementioned multiple access technologies have been adopted in various telecommunications standards to provide a common protocol enabling different user equipment to communicate at the city, country, region, and even global levels. NR (also known as 5G) is a set of enhancements to the LTE mobile standard released by 3GPP. NR is designed to better support mobile broadband internet access by improving spectrum efficiency, reducing costs, improving service, using new spectrum, and better integrating with other open standards such as Orthogonal Frequency Division Multiplexing (OFDM) with Cyclic Prefix (CP) on the downlink (DL) and CP-OFDM and / or SC-FDM (e.g., also known as Discrete Fourier Transform Extended OFDM (DFT-s-OFDM)) on the uplink (UL), as well as supporting beamforming, multiple-input multiple-output (MIMO) antenna technologies and carrier aggregation. Further improvements to LTE, NR, and other radio access technologies remain useful as the demand for mobile broadband access continues to increase. Summary of the Invention

[0029] 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 recognize 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.

It should be understood that any aspect of the disclosure herein may be embodied by one or more elements of the claims.

[0030] 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"). 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.

[0031] It should be noted that while the terms commonly associated with 5G or NR radio access technology (RAT) may be used to describe the aspects, the aspects of this disclosure may be applied to other RATs, such as 3G RAT, 4G RAT and / or RATs after 5G (e.g., 6G).

[0032] Figure 1 This is a diagram illustrating an example of a wireless network 100 according to this disclosure. Wireless network 100 may be or may include elements of a 5G (NR) network and / or an LTE network, as well as other examples. Wireless network 100 may include multiple base stations 110 (shown as BS 110a, BS 110b, BS 110c, and BS 110d) and other network entities. A base station (BS) is an entity that communicates with user equipment (UE) and may also be referred to as an 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 geographic area. In 3GPP, the term "cell" may refer to the coverage area of ​​a BS and / or the BS subsystem serving that coverage area, depending on the context in which the term is used.

[0033] 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. 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.

[0034] In some respects, the cell may not necessarily be stationary, and the geographical area of ​​the cell may move depending on the location of the mobile BS. In some respects, BSs may 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 (e.g., direct physical connections or virtual networks).

[0035] 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 BS 110d can communicate with macro BS 110a and UE 120d to facilitate communication between BS 110a and UE 120d. A relay BS can also be referred to as a relay station, relay base station, repeater, etc.

[0036] Wireless network 100 can be a heterogeneous network comprising different types of Base Stations (BSs) (e.g., macro BSs, pico BSs, femto BSs, repeater BSs, etc.). These different types of BSs can have different transmit power levels, different coverage areas, and different interference effects 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 repeater BSs can have lower transmit power levels (e.g., 0.1 to 2 watts).

[0037] 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. The BSs can also communicate with each other directly or indirectly via wireless or wired backhaul.

[0038] 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 an access terminal, 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, GPS device, or any other suitable device configured to communicate via wireless or wired media.

[0039] 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, and / or location tags that can communicate 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 that houses the components of UE 120 (e.g., processor components and / or memory components). In some aspects, the processor components and memory components can be coupled together. For example, the processor components (e.g., one or more processors) and memory components (e.g., memory) can be operatively coupled, communicatively coupled, electronically coupled, and / or electrically coupled.

[0040] 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.

[0041] In some respects, two or more UEs 120 (e.g., shown as UE 120a and UE 120e) may communicate directly using one or more sidelink channels (e.g., without using base station 110 as an intermediary device). For example, UEs 120 may 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 or vehicle-to-infrastructure (V2I) protocols) and / or mesh networks. In this case, UEs 120 may perform scheduling operations, resource selection operations, and / or other operations described elsewhere herein that are performed by base station 110.

[0042] Devices in the wireless network 100 can communicate using the electromagnetic spectrum, which can be subdivided into various categories, bands, channels, etc., based on frequency or wavelength. For example, devices in the wireless network 100 can communicate using an operating band with a first frequency range (FR1), which spans from 410 MHz to 7.125 GHz; and / or can communicate using an operating band with a second frequency range (FR2), which spans from 24.25 GHz to 52.6 GHz. The frequencies between FR1 and FR2 are sometimes referred to as intermediate frequency (IF) bands. Although a portion of FR1 is greater than 6 GHz, FR1 is generally referred to as the “sub-6 GHz” band. Similarly, FR2 is generally referred to as the “millimeter wave” band, although it is different from the extremely high frequency (EHF) band (30 GHz–300 GHz) designated as the “millimeter wave” band by the International Telecommunication Union (ITU). Therefore, unless otherwise explicitly stated, it should be understood that the terms "below 6 GHz," etc., if used herein, can broadly refer to frequencies below 6 GHz, frequencies within FR1, and / or intermediate frequency band frequencies (e.g., above 7.125 GHz). Similarly, unless otherwise explicitly stated, it should be understood that the terms "millimeter wave," etc., if used herein, can broadly refer to frequencies within the EHF band, frequencies within FR2, and / or intermediate frequency band frequencies (e.g., below 24.25 GHz). It is considered that frequencies included in FR1 and FR2 can be modified, and the techniques described herein are applicable to those modified frequency ranges.

[0043] As mentioned above, providing Figure 1 As an example. Other examples may differ from those for... Figure 1 The example described.

[0044] Figure 2This is a diagram illustrating an example 200 of communication between base station 110 and UE 120 in wireless network 100 according to the present disclosure. Base station 110 may be equipped with T antennas 234a to 234t, and UE 120 may be equipped with R antennas 252a to 252r, wherein typically T ≥ 1 and R ≥ 1.

[0045] At base station 110, transmitting 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 the Channel Quality Indicator (CQI) received from each UE, process the data of the 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. Transmitting processor 220 can also process system information (e.g., semi-static resource allocation information (SRPI)) and control information (e.g., CQI requests, permission, and / or upper-layer signaling), and provide overhead symbols and control symbols. Transmitting processor 220 can also generate reference symbols for reference signals (e.g., cell-specific reference signals (CRS) or demodulation reference signals (DMRS)) and synchronization signals (e.g., primary synchronization signal (PSS) or 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 OFDM) 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.

[0046] At UE 120, antennas 252a to 252r can receive downlink signals from base station 110 and / or other base stations and can provide the received signals to demodulators (DEMODs) 254a to 254r respectively. Each demodulator 254 can condition (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) to obtain received symbols. 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. 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 information and system information to controller / processor 280. The term "controller / processor" can refer to one or more controllers, one or more processors, or a combination thereof. The channel processor can determine Reference Signal Received Power (RSRP) parameters, Received Signal Strength Indicator (RSSI) parameters, Reference Signal Received Quality (RSRQ) parameters, and / or CQI parameters, among others. In some respects, one or more components of the UE 120 may be included in housing 284.

[0047] Network controller 130 may include a communication unit 294, a controller / processor 290, and a memory 292. Network controller 130 may include one or more devices, such as those in a core network. Network controller 130 may communicate with base station 110 via communication unit 294.

[0048] Antennas (e.g., antennas 234a to 234t and / or antennas 252a to 252r) may include or be contained in one or more antenna panels, antenna groups, antenna element sets, and / or antenna arrays, among other examples. Antenna panels, antenna groups, antenna element sets, and / or antenna arrays may include one or more antenna elements. Antenna panels, antenna groups, antenna element sets, and / or antenna arrays may include coplanar antenna element sets and / or non-coplanar antenna element sets. Antenna panels, antenna groups, antenna element sets, and / or antenna arrays may include antenna elements within a single housing and / or antenna elements within multiple housings. Antenna panels, antenna groups, antenna element sets, and / or antenna arrays may include one or more antenna elements coupled to one or more transmitting and / or receiving components, such as... Figure 2 One or more components.

[0049] On the uplink, at UE 120, the transmitting processor 264 can receive and process data from data source 262 and control information from controller / processor 280 (e.g., reports including RSRP, RSSI, RSRQ, and / or CQI). The transmitting processor 264 can also generate reference symbols for one or more reference signals. If applicable, the symbols from the transmitting processor 264 can be pre-encoded by TX MIMO processor 266, further processed by modulators 254a to 254r (e.g., for DFT-s-OFDM or CP-OFDM), and transmitted to base station 110. In some aspects, the modulator and demodulator (e.g., MOD / DEMOD 254) of UE 120 can be included in the modem of UE 120. In some aspects, UE 120 includes a transceiver. The transceiver may include any combination of antenna 252, modulator and / or demodulator 254, MIMO detector 256, receiver processor 258, transmitter processor 264, and / or TX MIMO processor 266. The transceiver may be used by a processor (e.g., controller / processor 280) and memory 282 to perform aspects of any of the methods described herein, for example, referenced in [reference]. Figures 5-7 As described.

[0050] 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 the decoded data to data sink 239 and the 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. Base station 110 may include scheduler 246 for scheduling UE 120 for downlink and / or uplink communications. In some aspects, modulators and demodulators (e.g., MOD / DEMOD 232) of base station 110 may be included in the modem of base station 110. In some aspects, base station 110 includes a transceiver. The transceiver may include any combination of antenna 234, modulator and / or demodulator 232, MIMO detector 236, receiver processor 238, transmitter processor 220, and / or TXMIMO processor 230. The transceiver may be used by a processor (e.g., controller / processor 240) and memory 242 to perform aspects of any of the methods described herein, for example, as referenced. Figures 5-7 As described.

[0051] 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 component may perform one or more techniques associated with V2X application determination of range parameters. 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 execute or direct, for example Figure 6 Process 600 Figure 7 The operation of process 700 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. In some aspects, memory 242 and / or memory 282 may include a non-transitory computer-readable medium storing one or more instructions (e.g., code and / or program code) for wireless communication. For example, one or more instructions, when executed by one or more processors of base station 110 and / or UE 120 (e.g., directly executed or executed after compilation, transformation, and / or interpretation), may cause one or more processors, UE 120, and / or base station 110 to perform or direct, for example... Figure 6 Process 600 Figure 7 The operation of process 700 and / or other processes as described herein. In some aspects, execution instructions may include run instructions, translation instructions, compilation instructions and / or interpretation instructions, and other examples.

In some aspects, such units may include combinations of... Figure 2 One or more components of the described UE 120, such as controller / processor 280, transmit processor 264, TX MIMO processor 266, MOD 254, antenna 252, DEMOD 254, MIMO detector 256, receive processor 258, etc.

[0053] Although Figure 2 The blocks are shown as different components, but the functions described above for these blocks can be implemented in a single hardware, software, or combined component or various combinations of components. For example, the functions described for the transmit processor 264, receive processor 258, and / or TX MIMO processor 266 can be performed by or under the control of the controller / processor 280.

[0054] As mentioned above, providing Figure 2As an example. Other examples may differ from those for... Figure 2 The example described.

[0055] Figure 3 This is a diagram illustrating example 300 of sidelink communication according to this disclosure.

[0056] like Figure 3 As shown, the first UE 305-1 can communicate with the second UE 305-2 (and one or more other UEs 305) via one or more sidelink channels 310. UEs 305-1 and 305-2 can communicate using one or more sidelink channels 310 for P2P communication, D2D communication, V2X communication (e.g., which may include V2V communication, V2I communication, vehicle-to-pedestrian (V2P) communication, mesh networking, etc.), etc. In some aspects, UEs 305 (e.g., UEs 305-1 and / or UEs 305-2) can correspond to one or more other UEs described elsewhere herein, such as UE 120. In some aspects, the one or more sidelink channels 310 can use the ProSe sidelink (PC5) interface and / or can operate in a high-frequency band (e.g., the 5.9 GHz band). Additionally or alternatively, UE 305 may use Global Navigation Satellite System (GNSS) timing to synchronize the timing of transmission time intervals (TTIs) (e.g., frames, subframes, time slots, symbols, etc.).

[0057] like Figure 3As further shown, one or more sidelink channels 310 may include a Physical Sidelink Control Channel (PSCCH) 315, a Physical Sidelink Shared Channel (PSSCH) 320, and / or a Physical Sidelink Feedback Channel (PSFCH) 325. PSCCH 315 can be used to transmit control information, similar to a Physical Downlink Control Channel (PDCCH) and / or a Physical Uplink Control Channel (PUCCH) for cellular communication with base station 110 via an access link or access channel. PSSCH 320 can be used to transmit data, similar to a Physical Downlink Shared Channel (PDSCH) and / or a Physical Uplink Shared Channel (PUSCH) for cellular communication with base station 110 via an access link or access channel. For example, PSCCH 315 may carry sidelink control information (SCI) 330, which may indicate various control information for sidelink communication, such as one or more resources (e.g., time resources, frequency resources, spatial resources, etc.), wherein a transport block (TB) 335 may be carried on PSSCH 320. TB 335 may include data. PSFCH 325 can be used for transmission-side link feedback 340, such as Hybrid Automatic Repeat Request (HARQ) feedback (e.g., Acknowledgment or Negative Acknowledgment (ACK / NACK) information), Transmit Power Control (TPC), Schedule Request (SR), etc.

[0058] In some aspects, one or more sidelink channels 310 may use resource pooling. For example, scheduling allocations may be transmitted across time using specific resource blocks (RBs) in a subchannel (e.g., included in SCI 330). In some aspects, data transmissions associated with scheduling allocations (e.g., on PSSCH 320) may occupy adjacent RBs in the same subframe as the scheduling allocation (e.g., using frequency division multiplexing). In some aspects, scheduling allocations and associated data transmissions are not transmitted on adjacent RBs.

[0059] In some aspects, UE 305 may operate using a transmission mode in which resource selection and / or scheduling is performed by UE 305 (e.g., instead of base station 110). In some aspects, UE 305 may perform resource selection and / or scheduling by sensing the availability of channels for transmission. For example, UE 305 may measure RSSI parameters (e.g., sidelink-RSSI (S-RSSI) parameters) associated with various sidelink channels, RSRP parameters (e.g., PSSCH-RSRP parameters) associated with various sidelink channels, RSRQ parameters (e.g., PSSCH-RSRQ parameters) associated with various sidelink channels, etc., and may select the channel for transmission for sidelink communication based at least in part on these measurements.

[0060] Alternatively or additionally, UE 305 may use SCI 330 received in PSCCH 315 to perform resource selection and / or scheduling. SCI 330 may indicate occupied resources, channel parameters, etc. In some aspects, SCI may indicate the range used for communication, and the processing of communication at the receiver UE or device may be at least partially based on this range. Alternatively or additionally, UE 305 may perform resource selection and / or scheduling by determining the Channel Busy Rate (CBR) associated with various sidelink channels, which may be used for rate control (e.g., by indicating the maximum number of resource blocks available to UE 305 for a particular subframe set).

[0061] In a transport mode where resource selection and / or scheduling is performed by UE 305, UE 305 can generate a sidelink grant and can send that grant in SCI 330. The sidelink grant can indicate one or more parameters (e.g., transport parameters) to be used for an upcoming sidelink transport, such as one or more resource blocks (e.g., for TB 335) to be used for an upcoming sidelink transport on PSSCH 320, one or more subframes to be used for an upcoming sidelink transport, MCS to be used for an upcoming sidelink transport, etc. In some aspects, UE 305 can generate a sidelink grant indicating one or more parameters (e.g., the period of the sidelink transport) for semi-persistent scheduling (SPS). Additionally or alternatively, UE 305 can generate sidelink grants for event-driven scheduling (e.g., for on-demand sidelink messages).

[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 example 400 of sidelink communication and access link communication according to this disclosure.

[0064] like Figure 4 As shown, the transmitter (Tx) UE 405 and the receiver (Rx) UE 410 can communicate with each other via a side link, as described above. Figure 3 As described. As further shown, in some sidelink modes, base station 110 may communicate with Tx UE 405 via a first access link. Additionally or alternatively, in some sidelink modes, base station 110 may communicate with Rx UE 410 via a second access link. Tx UE 405 and / or Rx UE 410 may correspond to one or more UEs described elsewhere herein, for example... Figure 1UE 120. Therefore, the direct link between UE 120 (e.g., via the PC5 interface) can be referred to as a sidelink, and the direct link between base station 110 and UE 120 (e.g., via the Uu interface) can be referred to as an access link. Sidelink communication can be sent via the sidelink, while access link communication can be sent via the access link. Access link communication can be downlink communication (from base station 110 to UE 120) or uplink communication (from UE 120 to base station 110).

[0065] As mentioned above, providing Figure 4 As an example. Other examples may differ from those for... Figure 4 The example described.

[0066] Some sidelink communication systems (e.g., V2X systems) provide range-based Quality of Service (QoS) mechanisms. For example, the transmitting UE can provide range parameters (e.g., in the SCI associated with the communication). When the receiving UE is outside the range specified by the range parameters, communication from the transmitting UE can be considered best-effort communication. Lower layers of the receiving UE (e.g., the physical or media access control layer) can use the range parameters to determine appropriate packet handling (e.g., hybrid automatic repeat request transmission, etc.) to achieve the QoS level indicated by the sidelink QoS parameters. Therefore, setting an appropriate range can reduce retransmissions, thereby saving resources, and can improve transmission performance regarding latency, etc.

[0067] In some respects, range parameters can be statically configured. For example, range parameters can be at least partially based on default values ​​mapped to a V2X service type associated with the V2X application that generates or triggers the communication. In some respects, the V2X service type can be a PSID (Provider Service ID) or an ITS-AID (Intelligent Transportation System Application Identifier). However, statically configured range parameters may not be suitable for all situations, even when applicable to a single V2X application. For example, a coordinated driving service V2X application may encounter different types of coordinated operations, different driving environments, different vehicle speeds, etc., so a single range parameter may prove inflexible and unsuitable for some scenarios. Similarly, a sensor-sharing service V2X application may encounter different speed limits, different message content, different maneuvers, and different distances associated with such maneuvers, so a single range parameter may prove inflexible and unsuitable for some scenarios.

[0068] Furthermore, in some respects, a UE-centric and symmetrical communication range may not be ideal for certain applications. For example, in sensor sharing, vehicles behind an autonomous vehicle (e.g., a vehicle including a UE that determines range parameters and transmits communications) may be more relevant to some communication purposes than vehicles in front of the autonomous vehicle. As another example, in intersection coordination, vehicles that have not yet entered the intersection may be more important for the intersection coordination operation than vehicles that have already left the intersection. However, the range defined by the range parameters could be a UE-centric circle, treating less important and more important vehicles equally. This could lead to suboptimal resource allocation and increased resource usage at less important vehicles (and the UEs associated with them), while more important vehicles might be excluded from the symmetrical range.

[0069] Some of the technologies and apparatus described herein enable V2X applications to provide range parameters for transmission. For example, a V2X application can determine the range parameters, at least in part, based on a set of parameters. This parameter set may include parameters associated with the V2X application, such as a set of parameters associated with coordinated driving services, a set of parameters associated with sensor sharing, etc. In some aspects, the service type of the V2X application may be one of the parameters used to determine the range parameters. In other aspects, the service type of the V2X application may not be one of the parameters used to determine the range parameters. In this way, the V2X application can determine appropriate range parameters for communication, which improves communication efficiency, improves resource utilization, and conserves communication resources.

[0070] Additionally or alternatively, the techniques and apparatus described herein provide asymmetric range parameters. For example, asymmetric range parameters can be implemented by modifying the transmitter UE area identifier or by defining a multi-value range parameter (e.g., having two or more range values) to indicate asymmetric range. In this way, the range of communication can be modified so that more important UEs (and vehicles) are within range, while less important UEs (and vehicles) are excluded. Therefore, coverage of more important UEs is improved, while resource usage associated with communication with less important UEs is reduced.

[0071] Figure 5 This is a diagram illustrating an example 500 of a V2X application defined with range parameters according to this disclosure. As shown, example 500 includes a V2X UE and a receiving (Rec) UE (e.g., UE 120, UE 305, UE 405, etc.). As further shown, the V2X UE is associated with a V2X application 505 (which may be implemented in the application layer of the V2X UE) and a physical / media access control (PHY / MAC) layer. As described below, the PHY / MAC layer can handle transmission and reception based on the range parameters provided and / or modified by the V2X application 505.

[0072] As shown by reference numeral 515, a V2X application 505 may determine range parameters based at least in part on a set of parameters associated with the V2X application 505. Typically, the V2X application 505 may be associated with baseline (e.g., default) range parameters, and modifications to the range parameters may be determined at least in part based on this set of parameters. The determination of range parameters for different V2X applications 505 is illustrated by reference numerals 520 and 525. In some examples below, specific range values ​​for the range parameters are provided. These range values ​​are provided by way of example only and do not limit the range values ​​that can be used. As described below, the parameter set may include vehicle speed. Additionally or alternatively, the parameter set may include the type of service of the V2X application, as described elsewhere herein.

[0073] V2X applications can obtain information indicating a set of parameters. In some aspects, a V2X application can obtain (e.g., receive, retrieve) one or more parameters from the parameter set from the PHY / MAC layer. For example, the PHY / MAC layer can determine and provide one or more parameters from the parameter set. As another example, the PHY / MAC layer can receive information indicating parameters from another UE and can provide this information to the V2X application. Additionally or alternatively, a V2X application can obtain (e.g., receive, retrieve) sensor information indicating one or more parameters from the parameter set. For example, the sensor information can be received from the V2X UE's sensors or can be transmitted by signals from another UE (e.g., a receiving UE or another UE).

[0074] As indicated by reference numeral 520, in some aspects, V2X application 505 may be a coordinated driving service V2X application (e.g., the service type may indicate a coordinated driving service V2X application). The coordinated driving service V2X application may handle signaling between V2X UEs (e.g., transmitter UE and receiver UE) to support coordinated driving, such as coordinated lane changes, queuing, intersection coordination, coordinated parking operations, etc. As further shown, V2X application 505 may modify the baseline range value associated with the coordinated driving service, at least in part, based on a set of parameters. In one example, the baseline range may be approximately 150 meters (m). If V2X application 505 determines that none of the parameters described in conjunction with reference numerals 520 and 525 indicate that the baseline range should be modified, then V2X application 505 may use the baseline range value as a range parameter.

[0075] In some aspects, V2X application 505 may modify the baseline range value at least in part based on the coordinated operation service type (e.g., the service type may indicate the coordinated operation service type of V2X application 505). For example, V2X application 505 may determine the range parameter to be 100m for the lane change coordinated operation service type, 200m for the queuing coordinated operation service type, or 50m for the intersection through coordinated operation service type or parking lot coordinated operation type. In some aspects, V2X application 505 may modify the baseline range value at least in part based on the operating environment. The operating environment may be associated with the environment type. For example, for overtaking maneuvers, overtaking on a bifurcated highway environment type may involve a shorter range than on a two-lane road environment type, because a two-lane road may involve more or more difficult maneuvering steps than a bifurcated highway. Therefore, the V2X application may determine a longer range parameter for a two-lane road environment type than for a bifurcated highway environment type. In some aspects, V2X application 505 may modify the baseline range value at least in part based on the vehicle speed associated with the V2X UE. For example, a V2X application 505 can determine a shorter range parameter for a low-speed vehicle than for a high-speed vehicle. More specifically, a V2X application can determine a range parameter of 50m for a vehicle traveling at 25 miles per hour (mph). As used herein, “vehicle speed” can refer to rate (e.g., the rate of movement over time, expressed as distance per unit of time) or speed (e.g., speed and direction of travel).

[0076] As indicated by reference numeral 525 in the accompanying drawings, in some aspects, the V2X application 505 may be a sensor sharing service V2X application (e.g., the service type may indicate a sensor sharing service for the V2X application). The sensor sharing service V2X application may process signaling between V2X UEs (e.g., a transmitter UE and a receiver UE) to support sensor sharing, such as signaling for locating other vehicles / UEs, information about hazards or other entities present on the road, actions performed by the vehicle (e.g., at least in part based on road curves, evasive maneuvers, etc.), and so on.

[0077] As further illustrated, V2X application 505 can modify the baseline range value associated with sensor-sharing services, at least in part, based on a set of parameters. In one example, the baseline range value could be approximately 250m, providing at least a gap of approximately 4 seconds even at high speeds. In some respects, V2X application 505 can modify the baseline range value, at least in part, based on road speed limits. For example, in a road area associated with a 65mph speed limit, the range parameter could be adjusted to 120m. In a road area associated with a 25mph speed limit, the range parameter could be adjusted to 50m. Thus, providing a shorter range parameter in road areas associated with lower speed limits improves resource utilization efficiency in scenarios where longer range values ​​might not be particularly beneficial.

[0078] In some respects, V2X applications 505 can modify baseline range values ​​at least in part based on the type of content of the communication. For example, in some cases, the communication may indicate the presence of an object, such as a hazard or pedestrian. If the object is a small or harmless entity, the V2X application can determine a shorter range value. If the object is a large object or an important or dangerous object (e.g., a large animal, pedestrian, large crater, etc.), the V2X application can determine a longer range value, which provides improved reliability in warning the receiving UE of the object's presence.

[0079] In some aspects, V2X applications 505 can modify baseline range values ​​at least in part based on the type of vehicle maneuver to be performed by the vehicle associated with the V2X UE. Vehicle maneuver types can include, for example, overtaking, lane changing, navigating in curves, platooning, etc. For example, if a road curve is detected that requires the vehicle to reduce its speed from 65 mph to 35 mph to pass through the curve, V2X application 505 can determine range parameters at least in part based on an acceptable or comfortable rate of deceleration and the distance to the road curve. In this case, the determination of range parameters can be at least in part based on the geometry of the road curve, vehicle characteristics, vehicle operator preferences, applicable regulations, weather conditions, etc. In some aspects, V2X applications 505 can modify baseline range values ​​at least in part based on the distance associated with the vehicle maneuver. For example, if the V2X transmitter UE is located at a greater distance from the start or midpoint of the vehicle's movement, the V2X application 505 can determine a shorter range parameter, and if the V2X transmitter UE is located at a shorter distance from the start or midpoint of the vehicle's movement, the V2X application 505 can determine a longer range parameter so that the receiver UE at an appropriate distance from the curve can obtain the information.

[0080] As indicated by reference numeral 530 in the attached figure, in some aspects, V2X applications can define asymmetric range parameters. An "asymmetric range parameter" can refer to a range parameter that includes a region asymmetrical about the location of the V2X UE on at least one axis. For example, a range parameter can define a circular region that is not centered on the V2X UE. As another example, a range parameter can define an elliptical region centered on the V2X UE along its major axis but not centered on the V2X UE along its minor axis. As yet another example, a range parameter can define an elliptical region centered on the V2X UE along both its major and minor axes. As yet another example, a range parameter can define an irregular shape.

[0081] In some respects, asymmetric range parameters can be based at least in part on the region associated with the UE. For example, V2X application 505 can modify the V2X region identifier to be different from the actual V2X region where the V2X UE is located. The V2X region identifier is a value included in a sidelink control information message (e.g., a second-phase sidelink control information message) that provides an indication of the UE's location. The region size can be configured based on the communication range and resource pool. Therefore, a circular (or non-circular) range can be defined relative to the modified region identifier. As an example, if V2X application 505 modifies the region identifier to be located east of the V2X UE's actual V2X region, then a receiver UE located further east of the V2X UE can be within the communication range relative to the range centered on the V2X UE, while a receiver UE located west of the V2X UE is less likely to be within that range compared to the case where the range is centered on the V2X UE. This approach can involve fewer modifications to the SCI compared to modified range parameters.

[0082] In some respects, asymmetric range parameters can explicitly indicate the asymmetric range. For example, the range value carried in the SCI (e.g., the Minimum Communication Range (MCR) value) can be modified to include multiple values. These multiple values ​​could define the major and minor axes of an ellipse centered on the V2X UE, the major and minor axes of an ellipse centered at an offset from the V2X UE specified by these multiple values, multiple ranges of an irregular shape that cumulatively defines the range, and so on. Explicitly indicating the asymmetric range provides increased flexibility in terms of the shape and extent of the asymmetric range compared to modifying the UE's region identifier.

[0083] As shown by reference numeral 535, the V2X application 505 may provide the PHY / MAC layer 510 with range parameters determined in conjunction with reference numerals 515 and / or 530. As shown by reference numeral 540, the PHY / MAC layer 510 may transmit communications based on the range parameters. For example, the PHY / MAC layer 510 may transmit an SCI 545 indicating the range parameters (e.g., an MCR value having one or more values ​​defining the range parameters), and may transmit V2X communications 550 associated with the SCI 545. As shown by reference numeral 555, the receiving UE may receive V2X communications 550 based on the range parameters specified by the SCI 545. For example, if the receiving UE is within the range specified by the range parameters, the receiving UE may comply with the QoS of the V2X communications 550 indicated by the SCI 545, and if the receiving UE is outside the range specified by the range parameters, the receiving UE may treat the V2X communications 550 as best-effort communications, e.g., not participate in HARQ feedback operations.

[0084] As noted above, providing Figure 5 As an example. Other examples may differ from those for... Figure 5 The example provided.

[0085] Figure 6 This is a diagram illustrating, for example, an example process 600 performed by a UE, according to this disclosure. Example process 600 is performed by a UE (e.g., UE 120, UE 305, UE 405, ...). Figure 5 Examples of devices (such as V2X UEs) performing operations associated with application-based range management for V2X communication.

[0086] like Figure 6 As shown, in some aspects, process 600 may include: obtaining information indicating a set of parameters associated with a V2X application (block 610). For example, devices (e.g., controller / processor 280, transmit processor 264, TX MIMO processor 266, modulator 254, antenna 252, etc.) may obtain (e.g., receive, retrieve) information indicating a set of parameters associated with a V2X application.

[0087] like Figure 6As shown, in some aspects, process 600 may include determining range parameters at least in part based on modifications to baseline range parameters (block 620). For example, devices (e.g., controller / processor 280, transmit processor 264, TX MIMO processor 266, modulator 254, antenna 252, etc.) may determine range parameters as described above. In some cases, "range parameter" may be used interchangeably with "range value". Range parameters may be at least in part based on modifications to baseline range parameters. For example, modifications may be at least in part based on a set of parameters associated with a V2X application. Baseline range parameters may be associated with the service type of the V2X application.

[0088] like Figure 6 Additionally, as shown, in some aspects, process 600 may include performing V2X communication at least in part based on range parameters (block 630). For example, the UE (e.g., using controller / processor 280, transmit processor 264, TX MIMO processor 266, modulator 254, antenna 252, etc.) may perform V2X communication at least in part based on range parameters, as described above.

In some aspects, the range parameters define an asymmetric range relative to the UE about at least one axis.

[0110] like Figure 7 Additionally, as shown, in some aspects, process 700 may include performing V2X communication based on range parameters (block 720).
