This application claims priority to European Patent Application 21 213 728.5, filed on Dec. 10, 2021, the entire contents of which are incorporated herein by reference.
Various aspects of this disclosure generally relate to the processing of multiple radio access technologies in a single radio controller.
New radio technologies enable use of other radio access technologies (e.g. they enable multi-access) through interfaces, such as, for example, via the non-3GPP Interworking Function (N3IWF) or the Trusted Non-3GPP Gateway Function (TNGF) interfaces in the 5th Generation Technology Standard (5G) of the 3rd Generation Partnership Project (3GPP). In conventional practice, separate radio access technologies, such as, for example, the wireless protocols under the Institute of Electrical and Electronics Engineers (IEEE) family standards IEEE 802.11 (Wi-Fi) and New Radio protocols such as 5G or the forthcoming 6th Generation Technology Standards (6G) are implemented with separate controllers and on separate radios. Network optimization, analytics, and spectrum management are also performed separately for each of the radio access technologies. The reliance on multiple radio results in increased cost. Furthermore, these separate implementations may create difficulties in maintaining quality of service (QoS), such as when the data traffic is transferred from 5G to WiFi.
In the drawings, like reference characters generally refer to the same parts throughout the different views. The drawings are not necessarily to scale, emphasis instead generally being placed upon illustrating the exemplary principles of the disclosure. In the following description, various exemplary embodiments of the disclosure are described with reference to the following drawings, in which:
The following detailed description refers to the accompanying drawings that show, by way of illustration, exemplary details and embodiments in which aspects of the present disclosure may be practiced.
The word “exemplary” is used herein to mean “serving as an example, instance, or illustration”. Any embodiment or design described herein as “exemplary” is not necessarily to be construed as preferred or advantageous over other embodiments or designs.
Throughout the drawings, it should be noted that like reference numbers are used to depict the same or similar elements, features, and structures, unless otherwise noted.
The phrase “at least one” and “one or more” may be understood to include a numerical quantity greater than or equal to one (e.g., one, two, three, four, [. . . ], etc.). The phrase “at least one of” with regard to a group of elements may be used herein to mean at least one element from the group consisting of the elements. For example, the phrase “at least one of” with regard to a group of elements may be used herein to mean a selection of: one of the listed elements, a plurality of one of the listed elements, a plurality of individual listed elements, or a plurality of a multiple of individual listed elements.
The words “plural” and “multiple” in the description and in the claims expressly refer to a quantity greater than one. Accordingly, any phrases explicitly invoking the aforementioned words (e.g., “plural [elements]”, “multiple [elements]”) referring to a quantity of elements expressly refers to more than one of the said elements. For instance, the phrase “a plurality” may be understood to include a numerical quantity greater than or equal to two (e.g., two, three, four, five, [. . . ], etc.).
The phrases “group (of)”, “set (of)”, “collection (of)”, “series (of)”, “sequence (of)”, “grouping (of)”, etc., in the description and in the claims, if any, refer to a quantity equal to or greater than one, i.e., one or more. The terms “proper subset”, “reduced subset”, and “lesser subset” refer to a subset of a set that is not equal to the set, illustratively, referring to a subset of a set that contains less elements than the set.
The term “data” as used herein may be understood to include information in any suitable analog or digital form, e.g., provided as a file, a portion of a file, a set of files, a signal or stream, a portion of a signal or stream, a set of signals or streams, and the like. Further, the term “data” may also be used to mean a reference to information, e.g., in form of a pointer. The term “data”, however, is not limited to the aforementioned examples and may take various forms and represent any information as understood in the art.
The terms “processor” or “controller” as, for example, used herein may be understood as any kind of technological entity that allows handling of data. The data may be handled according to one or more specific functions executed by the processor or controller. Further, a processor or controller as used herein may be understood as any kind of circuit, e.g., any kind of analog or digital circuit. A processor or a controller may thus be or include an analog circuit, digital circuit, mixed-signal circuit, logic circuit, processor, microprocessor, Central Processing Unit (CPU), Graphics Processing Unit (GPU), Digital Signal Processor (DSP), Field Programmable Gate Array (FPGA), integrated circuit, Application Specific Integrated Circuit (ASIC), etc., or any combination thereof. Any other kind of implementation of the respective functions, which will be described below in further detail, may also be understood as a processor, controller, or logic circuit. It is understood that any two (or more) of the processors, controllers, or logic circuits detailed herein may be realized as a single entity with equivalent functionality or the like, and conversely that any single processor, controller, or logic circuit detailed herein may be realized as two (or more) separate entities with equivalent functionality or the like.
As used herein, “memory” is understood as a computer-readable medium (e.g., a non-transitory computer-readable medium) in which data or information can be stored for retrieval. References to “memory” included herein may thus be understood as referring to volatile or non-volatile memory, including random access memory (RAM), read-only memory (ROM), flash memory, solid-state storage, magnetic tape, hard disk drive, optical drive, 3D XPoint™, among others, or any combination thereof.

The term “software” refers to any type of executable instruction, including firmware.
Unless explicitly specified, the term “transmit” encompasses both direct (point-to-point) and indirect transmission (via one or more intermediary points). Similarly, the term “receive” encompasses both direct and indirect reception. Furthermore, the terms “transmit,” “receive,” “communicate,” and other similar terms encompass both physical transmission (e.g., the transmission of radio signals) and logical transmission (e.g., the transmission of digital data over a logical software-level connection). For example, a processor or controller may transmit or receive data over a software-level connection with another processor or controller in the form of radio signals, where the physical transmission and reception is handled by radio-layer components such as RF transceivers and antennas, and the logical transmission and reception over the software-level connection is performed by the processors or controllers. The term “communicate” encompasses one or both of transmitting and receiving, i.e., unidirectional or bidirectional communication in one or both of the incoming and outgoing directions. The term “calculate” encompasses both ‘direct’ calculations via a mathematical expression/formula/relationship and ‘indirect’ calculations via lookup or hash tables and other array indexing or searching operations.
Herein are described procedures and devices to expand a New Radio platform, such an a platform operating on an Open Radio Access Network (Open RAN) architecture, to enable a converged enterprise wireless access platform that supports both licensed cellular technologies (e.g. such as 5G and/or 6G), and Wireless Local Area Network (WLAN)/unlicensed technologies, such as Wi-Fi. These procedures and devices may utilize one or more Open RAN concepts, including, but not limited to, architecture and/or concepts of the Telecom Infra Project (TIP) and/or of the O-RAN Alliance's Open RAN initiative. According to some aspects of this disclosure, the implementations of these Open RAN and TIP architectures may further utilize artificial intelligence (AI) for analytics and spectrum management.
TIP is a collaborative telecommunications initiative that generates processes and standards for global telecommunications infrastructure. One of TIP's projects is the OpenRAN initiative, which seeks to define vender-agnostic with open interfaces. TIP also promulgates OpenWiFi, which is a disaggregated Wi-Fi solution. Open RAN is an initiative of the O-RAN Alliance and includes a plurality of standards that allow for a virtualized RAN implementation.
Each of New Radio and Wi-Fi is a protocol for wireless transfer of data via electromagnetic signals. The relevant portions of the electromagnetic spectrum may be licensed (e.g. reserved, usually by a state or legal jurisdiction, for use only by a licensed user or users) or unlicensed (e.g. generally available for use by any user). New Radio signals may be principally or exclusively transmitted within the licensed radiofrequency spectrum, whereas Wi-Fi signals may be principally or exclusively transmitted within the unlicensed spectrum. The specific frequencies that are licensed or unlicensed may differ depending on a particular jurisdiction. For example, the unlicensed spectrum may differ between the United States, Europe, and parts of Asia. The principles and devices disclosed herein, however, are readily applicable to all licensed/unlicensed schemas, regardless of the jurisdiction.
Open RAN generally conceptualizes a RAN in terms of four functional blocks, which may be understood as a Radio Unit (RU), a Distributed Unit (DU), a Centralized Unit (CU), and a RAN Intelligent Controller (RIC). Since the specific tasks of the RU, DU, and CU are largely configurable, various configurations of these units will be described herein according to various aspects of the disclosure. The RU may generally handle digital frontend capabilities (e.g. digital/analog or analog/digital conversion, signal amplification, etc.) and portions of the Physical Layer (PHY or PHY Layer) according to the Open Systems Interconnection model (OSI model), and may also include functionality related to digital beamforming. The PHY Layer portions assigned to the RU may be understood as the Lower PHY Layer. The DU may receive an output of the RU for Receive (Rx) signals and may output to the RU for Transmit (Tx) signals. The DU may perform upper-lever PHY Layer functions, which may be referred to as the Higher PHY Layer. The DU may also perform Radio Link Control (RLC) and Medium Access Control (MAC) layer functions. The CU may perform primarily Radio Resource Control (RRC) and Packet Data Convergence Protocol (PDCP) functions.
The principles and devices disclosed herein include an architecture in which New Radio (licensed) and Wi-Fi (unlicensed) are combined into a single radio network with one controller that virtualizes both the licensed and unlicensed bands. Moreover, other aspects of the disclosure may describe optional enablement of intelligent spectrum management and network analytics across both licensed and unlicensed frequency bands.
As a general matter, such single-controller processing of multiple RATs may be achieved in part using partially software-implemented signal processing, such as, but not necessarily limited to, software-based baseband signal processing. That is, rather than relying on proprietary or RAT-specific hardware for baseband processing, one or more processors (e.g. one or more general purpose processors, one or more accelerators, one or more special-purpose processors, etc.) can be used to perform may lower layer functions in software. That is, a radiofrequency signal received at one or more antennas may travel to an analog/digital converter. A processor may then perform lower layer functions (e.g. one or more physical layer functions) on this digital signal. Depending on the Open RAN architecture, a processor in the RU may be configured to perform certain low Physical Layer functions, and a processor in the DU may be configured to perform certain high Physical Layer function, as well as optional performance of Radio Link Control and/or Medium Access Control. Open RAN permits various degrees of flexibility in the specific functions that are attributed to the RU, the DU, or the CU.
The processor in the RU and/or the DU may be configured to perform signal processing operations on signals of multiple RATs (for example, of New Radio (5G or 6G) and Wi-Fi). The processor of the RU and/or the DU may achieve this, for example, by using software containerization or software virtualization. Software containerization is a concept in which a standard unit of software that includes the relevant code and all of its dependencies is generated, for example, so that this standard unit of code can be quickly run among a plurality of computer environments. Software containers are generally understood to be standalone packages of executable code. One advantage of using containerization may be that containers are isolated from their environment and therefore may allow for uniformity in operation despite variations in the platform on which they operate. The RU and/or the DU processor may be configured to implement a software containerization using any known containerization method or protocol.
For example, the RU processor may implement a first software container, configured to process signals of a first RAT, and a second software container, configured to process signals of a second RAT.
To manage these containers, the device may include a container orchestrator, which may be configured to orchestrate the actions of any of the first plurality of software containers or the second plurality of software containers, and/or any of their subcontainers. Container orchestration is known, and therefore a recitation of container orchestration will not be included herein.
Alternatively, rather than relying on containerization, the RU and/or DU processors may employ machine virtualization. Machine virtualization is a technique in which one or more virtual machines are implemented on a processing core. The use of virtual machines may include an additional security benefit as compared to the use of containers, given that virtual machines are isolated from one another and utilize their own distinct and isolated resources. That is, a first virtual machine may be unable to read or modify data resources of a second virtual machine, and vice versa.
Throughout this description, the term “processing subsystem” (e.g. a “first processing subsystem,” a “second processing subsystem,”, etc.) are used. In an implementation using containers, such as a first container for a first RAT and a second container for a second RAT, the processing subsystem may be understood as referring to the container. In this manner, the first processing subsystem refers to a first container for processing a first RAT, a second processing subsystem refers to a second container for processing a second RAT, and so on. Should virtualization be employed instead, the first processing subsystem may be understood as referring to the first virtualization for processing a first RAT, a second processing subsystem may be understood as referring to the second virtualization for processing a first RAT, and so on.
According to an aspect of the disclosure, a configurable architecture for both licensed and unlicensed spectrum may be configured according to four pillars. In the first pillar, Wi-Fi functionally (e.g. such as Wi-Fi functionality that may conventionally be implemented in a radio head (RH)) and cellular New Radio functionally that may conventionally be implemented in a radio unit (RU), may be integrated into a single RH. This may be achieved in architecture in which a Wi-Fi access point (AP) is integrated within a radio head or the Wi-Fi AP with the DU. The RU may utilize the same antennas or different sets of antennas for the licensed and unlicensed bands. The RU processes signals (Tx or Rx) for each band. These processed signals are multiplexed for communication between the RU and the DU or CU. Signal transfer between the RU and the DU or CU may occur, for example, via an Ethernet cable.
The Open RAN architecture permits various functional split configurations, in which functions can be selectively assigned to the RU or the DU, and to some extent, the CU. For example, in an Open RAN 7-2 Split architecture, the RU is assigned radiofrequency functions e.g. amplification, A/D conversion, etc.) and low Physical Layer functions, whereas the DU performs high Physical Layer functions, as well as MAC and RLC. In an Open RAN 8-1 Split, the RH performs only the radiofrequency functions, and the DU performs all Physical Layer functions, as well as MAC and RLC.
According to a first aspect of the disclosure, this first pillar configuration may include the RU performing the cellular functions according to an ORAN split-7 architecture, wherein the RU performs some (e.g. lower) physical layer processing, and the RU performs all or substantially all functions of an Wi-Fi access point (e.g. an ORAN Split-2 architecture).
According to a second aspect of the disclosure, this first pillar configuration may include the RU performing the cellular functions according to the ORAN split-7 architecture, wherein the RU performs some (e.g. lower) physical layer processing, and the DU performs all or substantially all functions of the Wi-Fi access point (e.g. a Split-2 architecture).
According to a third aspect of the disclosure, this first pillar configuration may include the RU performing PHY layer and MAC layer cellular processing, and all or substantially all functions of the Wi-Fi access point (e.g. an Split-2 architecture).
In the third pillar, the CU may be configured to perform integrated network optimization and spectrum management across multiple bands. In this optional configuration, the single controller for both Wi-Fi and cellular processing may perform artificial intelligence (AI)-based analytics and/or intelligent spectrum management across different bands to be implemented in the CU. The AI may include, for example, one or more artificial neural networks (ANN). The ANN may include, for example, a input layer, one or more hidden layers, and an output layer, wherein each of the input layer, the one or more hidden layers, and the output layer include one or more nodes, which may be characterized with weights and or biases. The ANN may be trained to leverage the spectrum type based on policies, the use case scenario, the user configuration, or any of these.
The CU may perform these analytics by leveraging telemetric data from both licensed and unlicensed bands. For AI-implementation, training policies (machine learning or classic models) may include, but are not limited to, maintaining QoS when data is moved from Cellular to WiFi; maintaining security; maintaining reliability; maintaining mobility QoS/ease of handover; maintaining precise positioning; or any of these.

This may also result in improved network optimization and additional flexibility to deliver differentiated services. It may permit consistent Quality of Service (QoS) across cellular and WiFi communications, with seamless connectivity for the end user.
