Patent Application
20250088830
This application relates to wireless communication systems, and more particularly, to improving wireless communications between a user equipment (UE) and other wireless communication devices, including a UE of a vulnerable road user (VRU) sending a safety message.
Wireless communications systems are widely deployed to provide various types of communication content such as voice, video, packet data, messaging, broadcast, and so on. Safety messages, such as personal safety message (PSM) defined by SAE and vulnerable road user (VRU) awareness message (VAM) defined by ETSI, may allow cellular-vehicle-to-everything (C-V2X) capable UEs held by VRUs (e.g., pedestrians, joggers, cyclists, etc.) to broadcast their location, motion state, path history, and path prediction information to other C-V2X devices (e.g., vehicles, roadside units (RSUs), and other VRUs). A transmission frequency for transmitting such safety message (e.g., 1 Hz to 10 Hz) may be determined by the speed of UE held by the VRU.
However, there is no mechanism for adjusting the transmission frequency for the safety message based on static environmental conditions (e.g., a presence of protected bike lanes or sidewalks, etc.), dynamic environmental conditions (e.g., a number of surrounding vehicles, visibility conditions, etc.), and/or location-specific and type-specific historical conditions (e.g., intersection propensity for VRU accidents).
The following summarizes some aspects of the present disclosure to provide a basic understanding of the discussed technology. This summary is not an extensive overview of all contemplated features of the disclosure and is intended neither to identify key or critical elements of all aspects of the disclosure nor to delineate the scope of any or all aspects of the disclosure.

A significant increase in injuries and deaths involving vulnerable road users (VRUs) has been observed in the last several years. In addition, certain locations are more prone to such incidents than other locations. To address the aforementioned issues, a UE held by a VRU may transmit/broadcast a safety message (e.g., a personal safety message (PSM) or a vulnerable road user (VRU) awareness message (VAM)) to units (e.g., a C-V2X capable vehicle) nearby to reduce potential accident occurrences. Currently defined safety messages (e.g., PSM, VAM, etc.) modulate the message transmission frequency based on the speed of the UE held by the VRU. Modulation of the transmission frequency based on other criteria, such as the VRU motion status, or surrounding environmental conditions (e.g., lighting conditions, presence/absence of a sidewalk, etc.) is absent from the currently defined safety messages, potentially leading to untimely receipt of messages and inefficient battery utilization.
In accordance with the present disclosure, the transmission frequency for transmitting the safety message may be changed based on static environmental conditions (e.g., a presence of protected/unprotected bike lanes or sidewalks, etc.), dynamic environmental conditions (e.g., a number of surrounding vehicles, lighting/visibility conditions, etc.), and/or location-specific and/or type-specific historical conditions (e.g., roadway/intersection propensity for VRU-involved accidents). In order to provide a dynamic adjustment for the transmission frequency for the UE to transmit the safety message, the present application provides techniques for determining the transmission frequency dynamically based on data associated with VRU UEs.
Various aspects of the present disclosure relate generally to wireless communication and more particularly to wireless communications among VRU UEs, on-board units (OBUs), a network server, and/or service servers. Some aspects more specifically relate to a wireless communication between the VRU UE and the network server. The VRU UE may transmit, to the network unit, activity information associated with the UE, receive, from the network unit, an indication of a transmission frequency for transmitting a notification (e.g., the safety message), and transmit the notification based on the transmission frequency. The network server may adjust the transmission frequency based at least in part on the activity information associated with the VRU UE and/or data associated with the VRU UE. The activity information and/or the data associated with the VRU UE may be provided by the VRU UE itself, a third cloud-based entity (e.g., a weather forecast application, a traffic application, etc.), a service server (e.g., a database storing historical traffic records), and/or a nearby unit (e.g., a roadside unit, a C-V2X capable vehicle, another UE, etc.).
The VRU UE may transmit safety messages using different transmission frequencies in response to dynamically changing environmental conditions and/or the dynamic status of the VRU UE. The present disclosure provides methods and protocols for a network-based/cloud-based entity to determine and update the transmission frequency for safety messages for an individual UE or a group of UEs. The determination of the transmission frequency for the safety messages may be based on the type of VRU, a location of VRU UE, dynamic environmental conditions (e.g., weather, lighting, a number of surrounding vehicles, lighting/visibility conditions, etc.), static environmental conditions (e.g., a presence of protected/unprotected bike lanes or sidewalks, etc.), location-specific and/or type-specific historical conditions (e.g., roadway/intersection propensity for VRU-involved accidents), and/or a VRU-related accident history. One or more modules and/or components to perform the method(s) and/or protocol(s) may reside in an RSU, a gNB, and/or a cloud-based entity, and communicate the determined transmission frequency direction to the VRU UE(s) in dedicated or common signaling over a Uu message and/or a PC5 message.
Particular aspects of the subject matter described in this disclosure may be implemented to realize one or more of the following potential advantages. In some examples, by implementing wireless communication procedures according to aspects of the present disclosure, the described techniques may be used to improve the power utilization of UE through dynamically adjusting transmission frequency for transmitting a safety message, because the transmission frequency is being selected based on personalized and localized information, such that interference/collisions in transmission are reduced and, therefore, the UE may utilize a lower transmit power for the safety messages. Furthermore, the described techniques may reduce accidents for VRUs who carry a C-V2X capable UE. For example, the UE may broadcast a safety message using dynamically adjusted transmission frequency, which is determined by a network unit based on static conditions (e.g., being located in a unprotected sidewalk) and/or dynamic conditions (e.g., entering a busy area with a construction site), such that the UE may timely inform the surrounding units (e.g., other VRU UEs, RSUs, and/or C-V2X capable vehicles) with its presence and status.
A BS 105 may provide communication coverage for a macro cell or a small cell, such as a pico cell or a femto cell, and/or other types of cell. A macro cell generally covers a relatively large geographic area (e.g., several kilometers in radius) and may allow unrestricted access by UEs with service subscriptions with the network provider. A small cell, such as a pico cell, would generally cover a relatively smaller geographic area and may allow unrestricted access by UEs with service subscriptions with the network provider. A small cell, such as a femto cell, would also generally cover a relatively small geographic area (e.g., a home) and, in addition to unrestricted access, may also provide restricted access by UEs having an association with the femto cell (e.g., UEs in a closed subscriber group (CSG), UEs for users in the home, and the like). A BS for a macro cell may be referred to as a macro BS. A BS for a small cell may be referred to as a small cell BS, a pico BS, a femto BS or a home BS. In the example shown in
The network 100 may support synchronous or asynchronous operation. For synchronous operation, the BSs may have similar frame timing, and transmissions from different BSs may be approximately aligned in time. For asynchronous operation, the BSs may have different frame timing, and transmissions from different BSs may not be aligned in time.
The UEs 115 may be dispersed throughout the wireless network 100, and each UE 115 may be stationary or mobile. A UE 115 may also be referred to as a terminal, a mobile station, a subscriber unit, a station, or the like. A UE 115 may be a cellular phone, a personal digital assistant (PDA), a wireless modem, a wireless communication device, a handheld device, a tablet computer, a laptop computer, a cordless phone, a wireless local loop (WLL) station, or the like. In one aspect, a UE 115 may be a device that includes a Universal Integrated Circuit Card (UICC). In another aspect, a UE may be a device that does not include a UICC. In some aspects, the UEs 115 that do not include UICCs may also be referred to as internet of everything (IoE) devices. The UEs 115a-115d are examples of mobile smart phone-type devices accessing network 100. A UE 115 may also be a machine specifically configured for connected communication, including machine type communication (MTC), enhanced MTC (eMTC), narrowband IoT (NB-IoT) and the like. The UEs 115e-115h are examples of various machines configured for communication that access the network 100. The IoT devices may include one or more sensors and be configured for communication with a BS 105 and/or a UE 115. The UEs 115i-115k are examples of vehicles equipped with wireless communication devices configured for communication that access the network 100. A UE 115 may be able to communicate with any type of the BSs, whether macro BS, small cell, or the like. In
In operation, the BSs 105a-105c may serve the UEs 115a and 115b using 3D beamforming and coordinated spatial techniques, such as coordinated multipoint (CoMP) or multi-connectivity. The macro BS 105d may perform backhaul communications with the BSs 105a-105c, as well as small cell, the BS 105f. The macro BS 105d may also transmits multicast services which are subscribed to and received by the UEs 115c and 115d. Such multicast services may include mobile television or stream video, or may include other services for providing community information, such as weather emergencies or alerts, such as Amber alerts or gray alerts.
The BSs 105 may also communicate with a core network. The core network may provide user authentication, access authorization, tracking, Internet Protocol (IP) connectivity, and other access, routing, or mobility functions. At least some of the BSs 105 (e.g., which may be an example of an evolved NodeB (eNB) or an access node controller (ANC)) may interface with the core network 130 through backhaul links (e.g., S1, S2, etc.) and may perform radio configuration and scheduling for communication with the UEs 115. In various examples, the BSs 105 may communicate, either directly or indirectly (e.g., through core network), with each other over backhaul links (e.g., X1, X2, etc.), which may be wired or wireless communication links.
The network 100 may also support mission critical communications with ultra-reliable and redundant links for mission critical devices, such as the UE 115e, which may be a vehicle (e.g., a car, a truck, a bus, an autonomous vehicle, an aircraft, a boat, etc.). Redundant communication links with the UE 115e may include links from the macro BSs 105d and 105e, as well as links from the small cell BS 105f. Other machine type devices, such as the UE 115f (e.g., a thermometer), the UE 115g (e.g., smart meter), the UE 115h (e.g., wearable device) may communicate through the network 100 either directly with BSs, such as the small cell BS 105f, and the macro BSs 105d and 105e, or in multi-hop configurations by communicating with another user device which relays its information to the network, such as the UE 115f communicating temperature measurement information to the smart meter, the UE 115g, which is then reported to the network through the small cell BS 105f. In some aspects, the UE 115h may harvest energy from an ambient environment associated with the UE 115h. The network 100 may also provide additional network efficiency through dynamic, low-latency TDD/FDD communications, such as vehicle-to-vehicle (V2V), vehicle-to-everything (V2X), C-V2X communications between a UE 115i, 115j, or 115k and other UEs 115, and/or vehicle-to-infrastructure (V2I) communications between a UE 115i, 115j, or 115k and a BS 105.
In some implementations, the network 100 utilizes OFDM-based waveforms for communications. An OFDM-based system may partition the system BW into multiple (K) orthogonal subcarriers, which are also commonly referred to as subcarriers, tones, bins, or the like. Each subcarrier may be modulated with data. In some instances, the subcarrier spacing between adjacent subcarriers may be fixed, and the total number of subcarriers (K) may be dependent on the system BW. The system BW may also be partitioned into subbands. In other instances, the subcarrier spacing and/or the duration of TTIs may be scalable.
In some instances, the BSs 105 may assign or schedule transmission resources (e.g., in the form of time-frequency resource blocks (RB)) for downlink (DL) and uplink (UL) transmissions in the network 100. DL refers to the transmission direction from a BS 105 to a UE 115, whereas UL refers to the transmission direction from a UE 115 to a BS 105. The communication may be in the form of radio frames. A radio frame may be divided into a plurality of subframes, for example, about 10. Each subframe may be divided into slots, for example, about 2. Each slot may be further divided into mini-slots. In a FDD mode, simultaneous UL and DL transmissions may occur in different frequency bands. For example, each subframe includes a UL subframe in a UL frequency band and a DL subframe in a DL frequency band. In a TDD mode, UL and DL transmissions occur at different time periods using the same frequency band. For example, a subset of the subframes (e.g., DL subframes) in a radio frame may be used for DL transmissions and another subset of the subframes (e.g., UL subframes) in the radio frame may be used for UL transmissions.
The DL subframes and the UL subframes may be further divided into several regions. For example, each DL or UL subframe may have pre-defined regions for transmissions of reference signals, control information, and data. Reference signals are predetermined signals that facilitate the communications between the BSs 105 and the UEs 115. For example, a reference signal may have a particular pilot pattern or structure, where pilot tones may span across an operational BW or frequency band, each positioned at a pre-defined time and a pre-defined frequency. For example, a BS 105 may transmit cell specific reference signals (CRSs) and/or channel state information-reference signals (CSI-RSs) to enable a UE 115 to estimate a DL channel. Similarly, a UE 115 may transmit sounding reference signals (SRSs) to enable a BS 105 to estimate a UL channel. Control information may include resource assignments and protocol controls. Data may include protocol data and/or operational data. In some instances, the BSs 105 and the UEs 115 may communicate using self-contained subframes. A self-contained subframe may include a portion for DL communication and a portion for UL communication. A self-contained subframe may be DL-centric or UL-centric. A DL-centric subframe may include a longer duration for DL communication than for UL communication. A UL-centric subframe may include a longer duration for UL communication than for UL communication.
In some instances, the network 100 may be an NR network deployed over a licensed spectrum. The BSs 105 may transmit synchronization signals (e.g., including a primary synchronization signal (PSS) and a secondary synchronization signal (SSS)) in the network 100 to facilitate synchronization. The BSs 105 may broadcast system information associated with the network 100 (e.g., including a master information block (MIB), remaining minimum system information (RMSI), and other system information (OSI)) to facilitate initial network access. In some instances, the BSs 105 may broadcast the PSS, the SSS, and/or the MIB in the form of synchronization signal blocks (SSBs) over a physical broadcast channel (PBCH) and may broadcast the RMSI and/or the OSI over a physical downlink shared channel (PDSCH).
In some instances, a UE 115 attempting to access the network 100 may perform an initial cell search by detecting a PSS from a BS 105. The PSS may enable synchronization of period timing and may indicate a physical layer identity value. The UE 115 may then receive an SSS. The SSS may enable radio frame synchronization, and may provide a cell identity value, which may be combined with the physical layer identity value to identify the cell. The SSS may also enable detection of a duplexing mode and a cyclic prefix length. The PSS and the SSS may be located in a central portion of a carrier or any suitable frequencies within the carrier.
After receiving the PSS and SSS, the UE 115 may receive a MIB. The MIB may include system information for initial network access and scheduling information for RMSI and/or OSI. After decoding the MIB, the UE 115 may receive RMSI and/or OSI. The RMSI and/or OSI may include radio resource control (RRC) information related to random access channel (RACH) procedures, paging, control resource set (CORESET) for physical downlink control channel (PDCCH) monitoring, physical uplink control channel (PUCCH), physical uplink shared channel (PUSCH), power control, SRS, and cell barring.
After obtaining the MIB, the RMSI and/or the OSI, the UE 115 may perform a random access procedure to establish a connection with the BS 105. For the random access procedure, the UE 115 may transmit a random access preamble and the BS 105 may respond with a random access response. Upon receiving the random access response, the UE 115 may transmit a connection request to the BS 105 and the BS 105 may respond with a connection response (e.g., contention resolution message).
After establishing a connection, the UE 115 and the BS 105 may enter a normal operation stage, where operational data may be exchanged. For example, the BS 105 may schedule the UE 115 for UL and/or DL communications. The BS 105 may transmit UL and/or DL scheduling grants to the UE 115 via a PDCCH. The BS 105 may transmit a DL communication signal to the UE 115 via a PDSCH according to a DL scheduling grant. The UE 115 may transmit a UL communication signal to the BS 105 via a PUSCH and/or PUCCH according to a UL scheduling grant.
The network 100 may be designed to enable a wide range of use cases. While in some examples a network 100 may utilize monolithic base stations, there are a number of other architectures which may be used to perform aspects of the present disclosure. For example, a BS 105 may be separated into a remote radio head (RRH) and baseband unit (BBU). BBUs may be centralized into a BBU pool and connected to RRHs through low-latency and high-bandwidth transport links, such as optical transport links. BBU pools may be cloud-based resources. In some aspects, baseband processing is performed on virtualized servers running in data centers rather than being co-located with a BS 105. In another example, based station functionality may be split between a remote unit (RU), distributed unit (DU), and a central unit (CU). An RU generally performs low physical layer functions while a DU performs higher layer functions, which may include higher physical layer functions. A CU performs the higher RAN functions, such as radio resource control (RRC).
For simplicity of discussion, the present disclosure refers to methods of the present disclosure being performed by base stations, or more generally network entities, while the functionality may be performed by a variety of architectures other than a monolithic base station. In addition to disaggregated base stations, aspects of the present disclosure may also be performed by a centralized unit (CU), a distributed unit (DU), a radio unit (RU), a Near-Real Time (Near-RT) RAN Intelligent Controller (RIC), a Non-Real Time (Non-RT) RIC, IAB node, a relay node, a sidelink node, etc.
In some aspects, a UE 115 may transmit, to a network unit, activity information associated with the UE 115. The UE 115 may receive, from the network unit, an indication of a transmission frequency for transmitting a notification. The transmission frequency may be based at least in part on the activity information associated with the UE 115. The UE 115 may transmit the notification based on the transmission frequency.
In some aspects, a first wireless communication device (e.g., a BS 105, and/or another UE 115, such as a roadside unit) may receive, from one or more UEs 115 and one or more second wireless communication devices (e.g., another BS 105, yet another UE 115, a network unit, and/or a cloud-based entity), data associated with the one or more UEs 115. The first wireless communication device may send, to the one or more UEs 115, an indication of a transmission frequency for transmitting a notification. The transmission frequency may be based at least in part on the data associated with the one or more UEs 115.
In some aspects, a first wireless communication device 105 may receive, from one or more UEs 115 and one or more second wireless communication devices 105, data associated with the one or more UEs 115. The first wireless communication device 105 may send, to the one or more UEs 115, an indication of a transmission frequency for transmitting a notification. The transmission frequency may be based at least in part on the data associated with the one or more UEs 115.
Each of the units, i.e., the CUs 210, the DUs 230, the RUs 240, as well as the Near-RT RICs 225, the Non-RT RICs 215 and the SMO Framework 205, may include one or more interfaces or be coupled to one or more interfaces configured to receive or transmit signals, data, or information (collectively, signals) via a wired or wireless transmission medium. Each of the units, or an associated processor or controller providing instructions to the communication interfaces of the units, may be configured to communicate with one or more of the other units via the transmission medium. For example, the units may include a wired interface configured to receive or transmit signals over a wired transmission medium to one or more of the other units. Additionally, the units may include a wireless interface, which may include a receiver, a transmitter or transceiver (such as a radio frequency (RF) transceiver), configured to receive or transmit signals, or both, over a wireless transmission medium to one or more of the other units.
In some aspects, the CU 210 may host one or more higher layer control functions. Such control functions may include radio resource control (RRC), packet data convergence protocol (PDCP), service data adaptation protocol (SDAP), or the like. Each control function may be implemented with an interface configured to communicate signals with other control functions hosted by the CU 210. The CU 210 may be configured to handle user plane functionality (i.e., Central Unit-User Plane (CU-UP)), control plane functionality (i.e., Central Unit-Control Plane (CU-CP)), or a combination thereof. In some implementations, the CU 210 may be logically split into one or more CU-UP units and one or more CU-CP units. The CU-UP unit may communicate bidirectionally with the CU-CP unit via an interface, such as the E1 interface when implemented in an O-RAN configuration. The CU 210 may be implemented to communicate with the DU 230, as necessary, for network control and signaling.
The DU 230 may correspond to a logical unit that includes one or more base station functions to control the operation of one or more RUs 240. In some aspects, the DU 230 may host one or more of a radio link control (RLC) layer, a medium access control (MAC) layer, and one or more high physical (PHY) layers (such as modules for forward error correction (FEC) encoding and decoding, scrambling, modulation and demodulation, or the like) depending, at least in part, on a functional split, such as those defined by the 3rd Generation Partnership Project (3GPP). In some aspects, the DU 230 may further host one or more low PHY layers. Each layer (or module) may be implemented with an interface configured to communicate signals with other layers (and modules) hosted by the DU 230, or with the control functions hosted by the CU 210.
Lower-layer functionality may be implemented by one or more RUs 240. In some deployments, an RU 240, controlled by a DU 230, may correspond to a logical node that hosts RF processing functions, or low-PHY layer functions (such as performing fast Fourier transform (FFT), inverse FFT (iFFT), digital beamforming, physical random access channel (PRACH) extraction and filtering, or the like), or both, based at least in part on the functional split, such as a lower layer functional split. In such an architecture, the RU(s) 240 may be implemented to handle over the air (OTA) communication with one or more UEs 115. In some implementations, real-time and non-real-time aspects of control and user plane communication with the RU(s) 240 may be controlled by the corresponding DU 230. In some scenarios, this configuration may enable the DU(s) 230 and the CU 210 to be implemented in a cloud-based RAN architecture, such as a vRAN architecture.
The SMO Framework 205 may be configured to support RAN deployment and provisioning of non-virtualized and virtualized network elements. For non-virtualized network elements, the SMO Framework 205 may be configured to support the deployment of dedicated physical resources for RAN coverage requirements which may be managed via an operations and maintenance interface (such as an O1 interface). For virtualized network elements, the SMO Framework 205 may be configured to interact with a cloud computing platform (such as an open cloud (O-Cloud) 290) to perform network element life cycle management (such as to instantiate virtualized network elements) via a cloud computing platform interface (such as an O2 interface). Such virtualized network elements may include CUs 210, DUs 230, RUs 240 and Near-RT RICs 225. In some implementations, the SMO Framework 205 may communicate with a hardware aspect of a 4G RAN, such as an open eNB (O-eNB) 211, via an O1 interface. Additionally, in some implementations, the SMO Framework 205 may communicate directly with one or more RUs 240 via an O1 interface.

In some aspects, the OBU(s) 304 may provide blind spot monitor (BSM)-related data, including a type of vehicle, a location of vehicle, and a heading direction/speed of vehicle. In some aspects, the VRU UE(s)302 and the OBU(s) 304 may transmit data over a Uu message or a PC5 message (e.g., a PC5-Radio Resource Control (RRC) message, or a PC5 Signaling (PC5-S) message). In some aspects, the service server 308 may provide a location-specific VRU accident history, a type-specific VRU accident history, and a road topology information. The location-specific VRU accident history may include VRU accident occurrence conditions, including time-of-day, weather, and lighting conditions. For example, the location-specific VRU accident history may indicate that a VRU accident may have a higher chance to happen during night time in this area. The type-specific VRU accident history may include VRU accident occurrence frequency, such as accident occurrence frequency for a pedestrian, accident occurrence frequency for a bike, accident occurrence frequency for an e-Bike, accident occurrence frequency for a scooter, etc. The road topology information may include static features and dynamic features of road. For example, the static features of road may indicate whether this road includes a protected/unprotected sidewalk, a protected/unprotected bike lane, a signed/unsigned intersection, a signaled/non-signaled intersection, and/or a road shoulder. The dynamic features of road may indicate whether this road (including nearby area) currently (including near future) has a work zone, an accident, and/or a hazard weather.
The network server 306 may determine the transmission frequency for the VRU UE(s) 302 based on the data received from the VRU UE(s) 302, the OBU(s) 304, and/or the service server(s) 308 as discussed above. In one aspect for determining the transmission frequency for a single VRU UE 302, the network server 306 may identify location conditions (e.g., lighting, weather, and/or road conditions), a location-specific accident occurrence, a type-specific accident occurrence, an accident propensity, and an expected power source (e.g., cell phone battery, e-bike battery, etc.) for the VRU UE 302 based on the received data, and determine the transmission frequency for the VRU UE 302 based on the identified conditions associated with the VRU UE 302. In another aspect for determining a transmission frequency for multiple VRU UEs 302, the network server 306 may identify a number of VRU UEs 302 for each type of VRU (e.g., the number of pedestrian VRU UEs, the number of jogger VRU UEs, the number of bike VRU UEs, etc.), same type, and a location of VRU UEs 302 (e.g., a group of pedestrians at an intersection, a peloton of bikes cruising down the road, etc.) based on the received data, and determine a transmission frequency for the VRU UEs 302 based on the identified conditions.
The network server 306 may then provide the determined transmission frequency to the single VRU UE 302 or the multiple VRU UEs 302 individually in response to a corresponding determination of the transmission frequency (e.g., a determination of the transmission frequency for a single VRU UE or a group of VRU UEs). In some aspects, the network server 306 may send the transmission frequency to an individual VRU UE 302 and/or multiple VRU UEs 302 over a Uu message or a PC5 message (e.g., a PC5-RRC message, or a PC5-S message). In some aspects, an exemplary PC5-RRC IE, dedicated message may be transmitted using UE-PSMTxFreqSidelink (dedicated signaling), and the field descriptions of UE-PSMTxFreqSidelink may be PSM-TxFrequency stating “Frequency for PSM sidelink transmission in Hz. Value 1=1 Hz, Value 2=2 Hz, and so on.” In some aspects, PSM-TxFrequency may be added to an existing PC5-RRC message. In some aspects, PSM-TxFrequency may be part of a PC5-S message via unicast, groupcast or broadcast. In some aspects, in an exemplary cell-wide configuration via common signaling (e.g., System Information Block Type 12 (SIB12)), PSM-TxFrequency may be added as a new information element (e.g., proposed NR RRC definitions).
