[0018] As will be appreciated by those skilled in the art, aspects of the embodiments may be embodied as systems, devices, methods, or program products. Thus, the embodiments may take the form of a complete hardware embodiment, a complete software embodiment (including firmware, resident software, microcode, etc.), or a combination of software and hardware aspects, which may all be generally referred to herein as a "circuit," "module," or "system." In addition, the embodiments may take the form of a program product embodied in one or more computer-readable storage devices stored in machine-readable code, computer-readable code, and / or program code, hereinafter referred to as code. The storage device may be tangible, non-temporary, and / or non-transmittable. The storage device may not embody signals. In a certain embodiment, the storage device employs only signals for accessing the code.

[0019] Certain functional units described in this specification may be labeled as modules to more particularly emphasize their implementation independence. For example, a module may be implemented as a hardware circuit comprising custom very large scale integration ("VLSI") circuits or gate arrays, off-the-shelf semiconductors such as logic chips, transistors, or other discrete components. A module may also be implemented in a programmable hardware device such as a field programmable gate array, programmable array logic, or a programmable logic device.

[0020] Modules may also be implemented in code and / or software executed by various types of processors. An identified code module may, for example, include one or more physical or logical blocks of executable code, which may, for example, be organized as objects, procedures, or functions. However, the executable files of the identified modules need not be physically together, but may include unrelated instructions stored in different locations that, when logically connected together, comprise the module and achieve the stated purpose of the module.

[0021] In fact, code module can be a single instruction or many instructions, and can even be distributed on several different code segments, among different programs and across several memory devices.Similarly, in this article, operational data can be identified and illustrated in module, and can be embodied and organized in the data structure of any appropriate type in any suitable form.Operational data can be collected as a single data set, or can be distributed in the different locations included on different computer-readable storage devices.When the part of module or module is implemented in software, the software part is stored on one or more computer-readable storage devices.

[0022] Any combination of one or more computer-readable media may be utilized. The computer-readable medium may be a computer-readable storage medium. The computer-readable storage medium may be a storage device that stores code. The storage device may be, for example, but not limited to, an electronic, magnetic, optical, electromagnetic, infrared, holographic, micromechanical, or semiconductor system, apparatus, or device, or any suitable combination of the foregoing.

[0023] More specific examples of storage devices (a non-exhaustive list) would include the following: an electrical connection with one or more cables, a portable computer diskette, a hard disk, random access memory ("RAM"), read-only memory ("ROM"), erasable programmable read-only memory ("EPROM" or flash memory), a portable compact disk read-only memory ("CD-ROM"), an optical storage device, a magnetic storage device, or any suitable combination of the foregoing. In the context of this document, a computer-readable storage medium may be any tangible medium that can contain or store a program for use by or in connection with an instruction execution system, apparatus, or device.

[0024] The code for performing the operations of the embodiment can be any number of lines and can be written in any combination of one or more programming languages ​​including object-oriented programming languages ​​such as Python, Ruby, Java, Smalltalk, C++, and traditional procedural programming languages ​​such as the "C" programming language, and / or machine languages ​​such as assembly language. The code can be executed entirely on the user's computer, partially on the user's computer, as a separate software package, partially on the user's computer, partially on a remote computer, or entirely on a remote computer or server. In the latter scenario, the remote computer can be connected to the user's computer through any type of network including a local area network ("LAN") or a wide area network ("WAN"), or a connection can be formed to an external computer (e.g., through the Internet using an Internet service provider).

[0025] References in this specification to "one embodiment," "an embodiment," or similar language mean that a particular feature, structure, or characteristic described in conjunction with that embodiment is included in at least one embodiment. Therefore, unless expressly stated otherwise, throughout this specification, the appearance of the phrases "in one embodiment," "in an embodiment," and similar language may, but need not, all refer to the same embodiment, but rather mean "one or more but not all embodiments." Unless expressly stated otherwise, the terms "comprise," "comprising," "having," and their variations mean "including but not limited to." Unless expressly stated otherwise, a list of enumerated items does not imply that any or all items are mutually exclusive. Unless expressly stated otherwise, the terms "a," "an," and "the" also refer to "one or more."

[0026] In addition, the features, structures or characteristics of the described embodiments may be combined in any appropriate manner. In the following description, many specific details are provided, such as examples of programming, software modules, user selections, network transactions, database queries, database structures, hardware modules, hardware circuits, hardware chips, etc., to provide a thorough understanding of the embodiments. However, those skilled in the art will recognize that the embodiments can be practiced without one or more of the specific details, or using other methods, components, materials, etc. In other cases, well-known structures, materials or operations are not shown or described in detail to avoid obscuring some aspects of the embodiments.

[0027] Aspects of the embodiments are described below with reference to schematic flow charts and / or schematic block diagrams of the methods, devices, systems, and program products according to the embodiments. It will be understood that each block of the schematic flow charts and / or schematic block diagrams and the combination of blocks in the schematic flow charts and / or schematic block diagrams can be implemented by code. The code can be provided to a processor of a general-purpose computer, a special-purpose computer, or other programmable data processing device to generate a machine so that instructions executed by the processor of the computer or other programmable data processing device create a means for implementing the functions / operations specified in the schematic flow charts and / or schematic block diagram blocks or multiple blocks.

[0028] The code may also be stored in a storage device that is capable of instructing a computer, other programmable data processing apparatus, or other device to operate in a particular manner so that the instructions stored in the storage device produce an article of manufacture including instructions that implement the functions / operations specified in the schematic flowchart and / or schematic block diagram box or multiple boxes.

[0029] The code may also be loaded onto a computer, other programmable data processing apparatus, or other device so that a series of operational steps are performed on the computer, other programmable apparatus, or other device to produce a computer-implemented process, so that the code executed on the computer or other programmable apparatus provides a process for implementing the functions / operations specified in the flowchart and / or block diagram block or blocks.

[0030] The schematic flow charts and / or schematic block diagrams in the accompanying drawings illustrate the architecture, functionality, and operation of possible implementations of devices, systems, methods, and program products according to different embodiments. In this regard, each box in the schematic flow charts and / or schematic block diagrams may represent a module, segment, or portion of code, which includes one or more executable instructions of the code for implementing a specified logical function.

[0031] It should also be noted that in some alternative implementations, the functions annotated in the blocks may occur out of the order noted in the figures. For example, two blocks shown in succession may actually be executed substantially simultaneously, or the blocks may sometimes be executed in the reverse order, depending on the functionality involved. Other steps and methods are contemplated that are equivalent in function, logic, or effect to one or more blocks, or portions thereof, of the illustrated figures.

[0032] Although various arrow types and line types may be employed in the flowcharts and / or block diagrams, it will be understood that they do not limit the scope of the respective embodiments. In fact, some arrows or other connectors may be used merely to indicate the logical flow of the depicted embodiments. For example, arrows may indicate wait or monitoring periods of unspecified duration between the enumerated steps of the depicted embodiments. It will also be noted that each block of the block diagrams and / or flowcharts, and combinations of blocks in the block diagrams and / or flowcharts, can be implemented by a dedicated hardware-based system that performs a specific function or operation, or by a combination of dedicated hardware and code.

[0033] The description of an element in each figure may refer to the elements of the previous figure. The same numerals refer to the same elements in all figures, including alternative embodiments of the same elements.

[0047] The transmitter 210 is used to provide UL communication signals to the network element 104, and the receiver 212 is used to receive DL communication signals from the network element 104, as described herein. In some embodiments, the receiver 212 can: receive resources for the second radio access technology from the first radio access technology; and receive sidelink radio bearer configuration information from the first radio access technology.

[0048] Although only one transmitter 210 and one receiver 212 are shown, the remote unit 102 may have any suitable number of transmitters 210 and receivers 212. The transmitter 210 and receiver 212 may be any suitable type of transmitter and receiver. In one embodiment, the transmitter 210 and receiver 212 may be part of a transceiver.

[0049] Figure 3 One embodiment of an apparatus 300 that can be used for multi-radio access technology communications is depicted. Apparatus 300 includes one embodiment of a network unit 104. Furthermore, network unit 104 can include a processor 302, a memory 304, an input device 306, a display 308, a transmitter 310, and a receiver 312. As can be appreciated, processor 302, memory 304, input device 306, display 308, transmitter 310, and receiver 312 can be substantially similar to processor 202, memory 204, input device 206, display 208, transmitter 210, and receiver 212, respectively, of remote unit 102.

[0050] In various embodiments, the transmitter 310 may: transmit resources for the second radio access technology from the first radio access technology; and transmit sidelink radio bearer configuration information from the first radio access technology.

[0051] Although only one transmitter 310 and one receiver 312 are shown, the network unit 104 may have any suitable number of transmitters 310 and receivers 312. The transmitter 310 and receiver 312 may be any suitable type of transmitter and receiver. In one embodiment, the transmitter 310 and receiver 312 may be part of a transceiver.

[0052] In some embodiments, two resource allocation modes may be used for each of NR and LTE V2X communications. The two resource allocation modes for LTE may be referred to as Mode 3 and Mode 4; and the two resource allocation modes for NR may be referred to as Mode 1 and Mode 2. These two modes may support direct V2X communications but may differ in how radio resources are allocated. In some embodiments, the cellular network allocates resources (e.g., the gNB allocates Mode 1 resources and the eNB allocates Mode 3 resources). In various embodiments, if Mode 2 and Mode 4 are used, these modes may not require cellular coverage, and vehicles may autonomously select their radio resources using a distributed scheduling scheme supported by a congestion control mechanism from a pre-configured resource pool. In some embodiments, the RAN of a UE within coverage may allocate Mode 2 and Mode 4 resources. In some embodiments, Mode 2 and / or Mode 4 may be considered baseline modes and may represent an alternative to 802.11p or DSRC.

[0053] In various embodiments, all resource allocation modes can meet latency requirements, accommodate high Doppler spread, and / or accommodate high vehicle density for V2X communications. In some embodiments, Mode 1 and Mode 3 can utilize a centralized RAN (e.g., gNB and / or eNB) scheduler. In some embodiments, the vehicle UE and RAN can communicate using a Uu interface (e.g., sending a BSR and / or SR from the transmitting V2X UE to the RAN in response to receiving a SL grant on the PDCCH (DCI)). In various embodiments, Mode 2 and Mode 4 can utilize a PC5 interface to facilitate direct LTE SL communication between two onboard UEs and / or can utilize distributed UE scheduling. In some embodiments, V2X Mode 2 and Mode 4 can operate without infrastructure support, even though the UE may be within RAN coverage. In such embodiments, resources can be shared with the Uu uplink. In some embodiments, such as in LTE V2X, only broadcast-type transmissions may be supported, while in other embodiments, such as in NR, both V2X unicast and multicast transmissions may be supported.

[0054] In some embodiments, cross-RAT V2X PC5 may be used. In such embodiments, LTE coverage may be used to control NR PC5 using a network-scheduled mode of operation. In various embodiments, the NR (e.g., gNB) controlling the LTE PC5 may be used in both network-scheduled and UE-autonomous modes of operation.

[0055] Figure 4 1 is a schematic block diagram illustrating one embodiment of a communication 400 for inter-RAT V2X resource allocation in NS mode. The communication 400 described herein may include one or more messages. The communication 400 includes communication between a UE 402 and a RAT-1 serving cell 404 (e.g., a first RAT).

[0056] In a first communication 406 transmitted between the UE 402 and the RAT-1 serving cell 404, an ongoing Uu Connect message is transmitted and received.

[0057] In a second communication 408 transmitted from UE 402 to RAT-1 serving cell 404, UE 402 transmits an interest indication to RAT-1 serving cell 404. UE 402 may use the interest indication to request V2X resources in RAT-2 (e.g., a second RAT). In the second communication 408, UE 402 may include a PC5 QoS profile (e.g., VQI, 5QI, PPPP, and / or PPPR) transmitted to RAT-1 serving cell 404.

[0058] In a third communication 410 transmitted from the RAT-1 serving cell 404 to the UE 402, the RAT-1 serving cell 404 provides configured resources (e.g., SPS and / or license-exempt Type 1 / Type 2), SLRB configurations for each of the indicated PC5 QoS profiles, and / or an indication that a pre-configuration (e.g., configuration) may be used (e.g., by not including any SLRB configuration). In some embodiments, the UE 402 configures a PC5 radio bearer on the RAT based on the information received from the RAT-1 serving cell 404 and may begin data transmission and / or reception using the PC5 radio bearer.

[0059] Figure 5 1 is a schematic block diagram illustrating one embodiment of a communication 500 for cross-RAT V2X resource allocation in UE autonomous mode. The communication 500 described herein may include one or more messages. The communication 500 includes communication between a UE 502 and a RAT-1 serving cell 504 (e.g., a first RAT).

[0060] In a first communication 506 transmitted between the UE 502 and the RAT-1 serving cell 504, an ongoing Uu Connect message is transmitted and received.

[0061] In a second communication 508 transmitted from the RAT-1 serving cell 504 to the UE 502, the RAT-1 serving cell 504 may perform a network broadcast of PC5 resources for RAT-2 (e.g., a second RAT), provide an SLRB configuration for each supported PC5 QoS profile for an SLRB configuration assumed as a minimum mandatory capability for cross-RAT communication of an NR V2X UE, and / or an explicit indication (e.g., a Boolean indication) indicating that no SLRB configuration is provided by the RAT-1 serving cell 504 or that the SLRB configuration is provided by the serving cell for RAT-2 using only RRC dedicated signaling. If the explicit indication indicates that no SLRB configuration is provided by the RAT-1 serving cell 504, the UE 502 may use the SLRB pre-configuration corresponding to each PC5 QoS profile for which data may be used for transmission in the UE 502. If the explicit indication indicates that the SLRB configuration is provided by the serving cell for RAT-2 using only RRC dedicated signaling, the UE 502 may send an indication of interest to the serving cell of RAT-2 using RRC signaling, and the network may then respond with an SLRB configuration corresponding to each indicated PC5 QoS profile. If the UE 502 is not RRC connected, a transition to the RRC connected state may be initiated to facilitate the transmission of the indication of interest.

[0062] Based on the network response, the UE 502 may make 510 a determination (eg, decision) of which SLRB configuration to use and may configure one or more SLRBs accordingly.

[0063] In certain embodiments, the UE 502 configures 512 a PC5 radio bearer on the RAT and starts data transmission and / or reception on the PC5 radio bearer.

[0064] In various embodiments, mode 1 and / or mode 3 inter-RAT resource allocation using only configured resources (e.g., SPS and / or configured grant type 1) via RRC signaling may be accomplished by providing network-scheduled configured resources via RRC signaling for inter-RAT V2X communication and implicitly and / or explicitly indicating by the network whether L2 and / or L1 configurations are provided by the RAN node for inter-RAT V2X communication. In such embodiments, if the serving cell does not provide pre-configured and / or designated L2 and / or L1 configurations for inter-RAT V2X communication, the UE may use the pre-configured and / or designated L2 and / or L1 configurations.

[0065] In some embodiments, if the scheduling information of the cell in SIB1 indicates that PC5 resources and / or SLRB configuration for RAT2 may be provided in the corresponding SIB, the UE uses an on-demand system information request for the serving cell of RAT-1. The on-demand system information may not be broadcast system information.

[0066] In certain embodiments, RAT-1 receives a SLRB configuration for each supported PC5 QoS profile (eg, VQI and / or 5QI) from an operations and maintenance ("O&M") entity or from a RAT-2 cell.

[0067] In various embodiments, the pre-configuration described herein may refer to a pre-provisioned SLRB configuration for each supported PC5 QoS profile (e.g., VQI and / or 5QI). In some embodiments, the pre-configuration described herein may refer to a specified SLRB configuration for each supported PC5 QoS profile (e.g., VQI and / or 5QI).
