Capability information for a user equipment

Abstract

Aspects relate to a UE adapting the capabilities it announces based on the network in which the UE is operating. In some examples, if a network currently supports a certain bandwidth, the UE can select the capabilities it will announce based on the supported bandwidth. In some examples, the UE can obtain information about which configurations the network has considered. In this case, the UE can select the capabilities it will announce based on such configurations.

Description

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This patent application claims priority to and the benefit of pending Indian Provisional Patent Application No. 202041022928, filed on June 1, 2020, entitled “CAPABILITY INFORMATION FOR WIRELESS COMMUNICATION DEVICE,” which is assigned to the assignee of this application and is hereby expressly incorporated herein by reference as if fully set forth below and for all applicable purposes. Technical Field

[0003]

[0011] The techniques discussed below relate generally to wireless communications, and more particularly to selecting and communicating capability information for user equipment.

[0004] introduction

[0005] A next-generation wireless communication system (e.g., 5GS) may include a 5G core network and a 5G radio access network (RAN), such as a new radio (NR)-RAN. The NR-RAN supports communication via one or more cells. For example, a wireless communication device (such as a user equipment (UE)) may access a first cell of a first base station (BS) (such as a gNB) and / or access a second cell of a second BS.

[0006] A base station (BS) can schedule access to a cell to support access by multiple UEs. For example, the BS can allocate different resources (e.g., time and frequency domain resources) to different UEs operating within the BS's cell. Furthermore, if a UE supports multiple radio frequency (RF) carriers, the BS can schedule the UE on one or more RF carriers.

[0033] Detailed description

[0034] The detailed description set forth below in conjunction with the accompanying drawings is intended as a description of various configurations and is not intended to represent the only configurations in which the concepts described herein may be practiced. This detailed description includes specific details to provide a thorough understanding of the various concepts. However, it will be apparent to those skilled in the art that these concepts may be practiced without these specific details. In some instances, well-known structures and components are shown in block diagram form to avoid overstating such concepts.

[0035] Although various aspects and examples are described in this application by explaining some examples, it will be understood by those skilled in the art that additional implementations and use cases can be generated in many different arrangements and scenarios. The innovations described herein can be implemented across many different platform types, devices, systems, shapes, sizes, and packaging arrangements. For example, various aspects and / or uses can be generated via integrated chip examples and other devices based on non-module components (e.g., end-user devices, vehicles, communication equipment, computing equipment, industrial equipment, retail / shopping equipment, medical equipment, artificial intelligence (AI) enabled devices, etc.). Although some examples may or may not be specifically for each use case or application, the wide applicability of the described innovations may occur. The scope of each implementation can range from chip-level or module components to non-module, non-chip-level implementations, and further to aggregated, distributed or original equipment manufacturer (OEM) devices or systems incorporating one or more aspects of the described innovations. In some practical environments, the devices incorporating the various aspects and features described may also necessarily include additional components and features for implementing and practicing the claimed and described examples. For example, the transmission and reception of wireless signals necessarily include several components for analog and digital purposes (e.g., hardware components including antennas, radio frequency (RF) chains, power amplifiers, modulators, buffers, processor(s), interleavers, adders / summers, etc.). The innovations described herein are intended to be practiced in a wide variety of devices, chip-level components, systems, distributed arrangements, end-user devices, and the like, of various sizes, shapes, and configurations.

[0036] A user equipment (UE) may have a defined set of capabilities. For example, a UE may support communication over a bandwidth range up to a certain maximum bandwidth. As another example, a UE may support communication via one or more multiple-input multiple-output (MIMO) layers up to a maximum number of MIMO layers.

[0037] In some scenarios, a network may configure resources for a UE without fully considering the capabilities of the UE. Various aspects of the present disclosure relate to selecting and communicating capability information for a UE based at least in part on how a network may configure resources for the UE.

[0038] In some examples, the UE may adapt the capabilities announced by the UE based on the network that the UE is currently operating in. For example, if a network (or a subset of networks) currently supports up to a certain bandwidth, the UE may modify its capability announcement to exclude bandwidths exceeding the bandwidth supported by the network.

[0039] In some examples, a UE may obtain information about which configurations the network (or a subset of the network) has considered when configuring resources for the UE and / or one or more other UEs. In this case, the UE may update its announcement rules to announce capabilities based on these configurations.

[0040] In some examples, the UE may request the network to adapt the resource configuration based on the capabilities of the UE. For example, in response to a resource misconfiguration by the network, the UE may send a message to the network requesting the network to modify the resource configuration.

[0041] In some examples, the UE may proactively send a message to the network to request a specific resource configuration. For example, the UE may send such a message in anticipation of future bandwidth requirements for the UE.

[0042] The various concepts presented throughout this disclosure can be implemented across a wide variety of telecommunication systems, network architectures, and communication standards. Figure 1 By way of illustrative example and not limitation, various aspects of the present disclosure are described with reference to a wireless communication system 100. The wireless communication system 100 includes three interacting domains: a core network 102, a radio access network (RAN) 104, and a user equipment (UE) 106. The wireless communication system 100 enables the UE 106 to perform data communications with an external data network 110, such as, but not limited to, the Internet.

[0043] The RAN 104 may implement any suitable wireless communication technology or technologies to provide radio access to the UE 106. As one example, the RAN 104 may operate in accordance with the Third Generation Partnership Project (3GPP) New Radio (NR) specifications, commonly referred to as 5G. As another example, the RAN 104 may operate under a hybrid of 5G NR and Evolved Universal Terrestrial Radio Access Network (eUTRAN) standards, commonly referred to as Long Term Evolution (LTE). 3GPP refers to this hybrid RAN as a Next Generation RAN, or NG-RAN. In another example, the RAN 104 may operate in accordance with both LTE and 5G NR standards. Of course, many other examples may be utilized within the scope of this disclosure.

[0044] As illustrated, the RAN 104 includes multiple base stations 108. Broadly speaking, a base station is a network element in a radio access network that is responsible for radio transmission and reception to or from a UE in one or more cellular cells. In different technologies, standards, or contexts, a base station may be referred to variously by those skilled in the art as a base transceiver station (BTS), a radio base station, a radio transceiver, a transceiver function, a basic service set (BSS), an extended service set (ESS), an access point (AP), a Node B (NB), an evolved Node B (eNB), a next generation Node B (gNB), a transmit reception point (TRP), or some other suitable terminology. In some examples, a base station may include two or more TRPs that may or may not be co-located. Each TRP may communicate on the same or different carrier frequencies within the same or different frequency bands. In an example where the RAN 104 operates according to both LTE and 5G NR standards, one of the base stations 108 may be an LTE base station, while another may be a 5G NR base station.

[0045] The radio access network 104 is further illustrated as supporting wireless communications for multiple mobile devices. A mobile device may be referred to as a user equipment (UE) 106 in the 3GPP standard, but may also be referred to as a mobile station (MS), subscriber station, mobile unit, subscriber unit, wireless unit, remote unit, mobile device, wireless device, wireless communication device, remote device, mobile subscriber station, access terminal (AT), mobile terminal, wireless terminal, remote terminal, handset, terminal, user agent, mobile client, client, or some other suitable terminology by those skilled in the art. UE 106 may be a device that provides access to network services to a user. In an example where RAN 104 operates according to both LTE and 5G NR standards, UE 106 may be an Evolved Universal Terrestrial Radio Access Network - New Radio Dual Connectivity (EN-DC) UE capable of simultaneously connecting to an LTE base station and an NR base station to receive data packets from both the LTE base station and the NR base station.

[0046] Within this document, a mobile device does not necessarily need to have mobile capabilities and can be stationary. The term mobile device or mobile equipment refers broadly to a wide variety of devices and technologies. A UE may include several hardware structural components sized, shaped, and arranged to facilitate communication; such components may include antennas, antenna arrays, RF chains, amplifiers, one or more processors, and the like electrically coupled to one another. For example, some non-limiting examples of mobile devices include mobile devices, cellular (cell) phones, smart phones, Session Initiation Protocol (SIP) phones, laptops, personal computers (PCs), notebooks, netbooks, smartbooks, tablets, personal digital assistants (PDAs), and a wide variety of embedded systems, e.g., corresponding to the Internet of Things (IoT).

[0047] Additionally, the mobile device may be a car or other transportation vehicle, a remote sensor or actuator, a robot or robotic device, a satellite radio, a Global Positioning System (GPS) device, an object tracking device, a drone, a multicopter, a quadcopter, a remote control device, a consumer and / or wearable device (such as glasses), a wearable camera, a virtual reality device, a smartwatch, a health or fitness tracker, a digital audio player (e.g., an MP3 player), a camera, a game console, etc. Additionally, the mobile device may be a digital home or smart home device, such as home audio, video, and / or multimedia equipment, an appliance, a vending machine, a smart lighting device, a home security system, a smart meter, etc. Additionally, the mobile device may be a smart energy device, a security device, a solar panel or solar array, municipal infrastructure equipment that controls electricity, lighting, water, etc. (e.g., a smart grid), industrial automation and enterprise equipment, a logistics controller, agricultural equipment, etc. Further, the mobile device may provide connected health or telemedicine support, i.e., healthcare at a distance. Telehealth devices may include telehealth monitoring devices and telehealth supervisory devices, whose communications may be given priority treatment or prioritized access over other types of information, for example, in the form of prioritized access for critical service data transmission and / or associated QoS for critical service data transmission.

[0048] The wireless communication between RAN 104 and UE 106 can be described as utilizing an air interface. Transmissions over the air interface from a base station (e.g., base station 108) to one or more UEs (e.g., UE 106) can be referred to as downlink (DL) transmissions. In some examples, the term downlink can refer to point-to-multipoint transmissions originating at a base station (e.g., base station 108). Another way to describe this point-to-multipoint transmission scheme can be to use the term broadcast channel multiplexing. Transmissions from a UE (e.g., UE 106) to a base station (e.g., base station 108) can be referred to as uplink (UL) transmissions. In some examples, the term uplink can refer to point-to-point transmissions originating at a UE (e.g., UE 106).

[0049] In some examples, access to the air interface may be scheduled, wherein a scheduling entity (e.g., a base station 108) allocates resources for communication among some or all devices and equipment within its service area or cell. Within the present disclosure, as discussed further below, a scheduling entity may be responsible for scheduling, assigning, reconfiguring, and releasing resources for one or more scheduled entities (e.g., UEs). That is, for scheduled communications, multiple UEs 106 (which may be scheduled entities) may utilize resources allocated by the scheduling entity 108.

[0050] Base station 108 is not the only entity that can serve as a scheduling entity. That is, in some examples, a UE can serve as a scheduling entity, thereby scheduling resources for one or more scheduled entities (e.g., one or more other UEs). For example, a UE can communicate with other UEs in a peer-to-peer or device-to-device manner and / or in a relay configuration.

[0051] like Figure 1 , a scheduling entity 108 may broadcast downlink traffic 112 to one or more scheduled entities 106. Broadly speaking, a scheduling entity 108 is a node or device responsible for scheduling traffic in a wireless communication network, including downlink traffic 112 and, in some examples, uplink traffic 116 and / or uplink control information 118 from one or more scheduled entities 106 to the scheduling entity 108. On the other hand, a scheduled entity 106 is a node or device that receives downlink control information 114 (including, but not limited to, scheduling information (e.g., grants), synchronization or timing information), or other control information from another entity in the wireless communication network, such as the scheduling entity 108.

[0052] Additionally, uplink and / or downlink control information and / or traffic information may be divided into frames, subframes, time slots, and / or symbols in time. As used herein, a symbol may refer to a time unit in which each subcarrier carries one resource element (RE) in an orthogonal frequency division multiplexing (OFDM) waveform. In some examples, a time slot may carry 7 or 14 OFDM symbols. A subframe may refer to a duration of 1 millisecond (ms). Multiple subframes or time slots may be grouped together to form a single frame or radio frame. Within the present disclosure, a frame may refer to a predetermined duration (e.g., 10 ms) for wireless transmission, wherein each frame includes, for example, 10 subframes of 1 ms each. Of course, these definitions are not required, and any appropriate scheme may be utilized to organize the waveform, and the various time divisions of the waveform may have any appropriate duration.

[0053] Generally speaking, base stations 108 may include a backhaul interface for communicating with a backhaul portion 120 of a wireless communication system. Backhaul 120 may provide a link between base stations 108 and core network 102. Furthermore, in some examples, a backhaul network may provide interconnection between respective base stations 108. Various types of backhaul interfaces may be employed using any suitable transport network, such as a direct physical connection, a virtual network, and the like.

[0054] The core network 102 may be part of the wireless communication system 100 and may be independent of the radio access technology used in the RAN 104. In some examples, the core network 102 may be configured according to a 5G standard (e.g., 5GC). In other examples, the core network 102 may be configured according to a 4G Evolved Packet Core (EPC), or any other suitable standard or configuration.

[0055] Now refer to Figure 2 , a schematic illustration of RAN 200 is provided by way of example and not limitation. In some examples, RAN 200 may be similar to that described above and in Figure 1 The same as RAN 104 explained in .

[0056] The geographic area covered by the RAN 200 may be divided into cellular regions (cells), which may be uniquely identified by a user equipment (UE) based on an identity broadcast from an access point or base station. Figure 2 Cells 202, 204, 206, and 208 are illustrated, each of which may include one or more sectors (not shown). A sector is a sub-area of ​​a cell. All sectors within a cell are served by the same base station. Radio links within a sector may be identified by a single logical identifier belonging to that sector. In a cell divided into sectors, multiple sectors within the cell may be formed by antenna groups, where each antenna is responsible for communicating with UEs in a portion of the cell.

[0057] Various base station arrangements can be used. For example, Figure 2 , two base stations 210 and 212 are shown in cells 202 and 204; and a third base station 214 is shown controlling a remote radio head (RRH) 216 in cell 206. That is, the base stations may have integrated antennas or may be connected to antennas or RRHs by feeder cables. In the illustrated example, cells 202, 204, and 206 may be referred to as macro cells because base stations 210, 212, and 214 support cells with large sizes. Additionally, base station 218 is shown in cell 208, which may overlap with one or more macro cells. In this example, cell 208 may be referred to as a small cell (e.g., a micro cell, a pico cell, a femto cell, a home base station, a Home NodeB, a Home eNodeB, etc.) because base station 218 supports cells with relatively small sizes. Cell sizing may be accomplished based on system design and component constraints.

[0058] It is understood that the radio access network 200 may include any number of wireless base stations and cellular cells. In addition, relay nodes may be deployed to extend the size or coverage area of ​​a given cellular cell. Base stations 210, 212, 214, 218 provide wireless access points to the core network for any number of mobile devices. In some examples, base stations 210, 212, 214, and / or 218 may be similar to those described above and in Figure 1 The same as the base station / scheduling entity 108 illustrated in FIG.

[0059] Figure 2 Further included is an unmanned aerial vehicle (UAV) 220, which may be a drone or a quadcopter. UAV 220 may be configured to function as a base station, or more specifically, as a mobile base station. That is, in some examples, the cell may not necessarily be stationary, and the geographic area of ​​the cell may be mobile depending on the location of a mobile base station, such as UAV 220.

[0060] Within the RAN 200, cells may include UEs that may be in communication with one or more sectors of each cell. In addition, each base station 210, 212, 214, and 218 may be configured to provide connectivity to the core network 102 (see FIG. 1 ) for all UEs in the corresponding cell. Figure 1) access point. For example, UEs 222 and 224 may be in communication with base station 210; UEs 226 and 228 may be in communication with base station 212; UEs 230 and 232 may be in communication with base station 214 via RRH 216; and UE 234 may be in communication with base station 218. In some examples, UEs 222, 224, 226, 228, 230, 232, 234, 236, 238, 240, and / or 242 may be in communication with the base stations described above and in Figure 1 2. In some examples, UAV 220 (e.g., a quadcopter) can be a mobile network node and can be configured to function as a UE. For example, UAV 220 can operate within cell 202 by communicating with base station 210.

[0061] In a further aspect of the RAN 200, sidelink signals may be used between UEs without relying on scheduling or control information from a base station. Sidelink communications may be used, for example, in device-to-device (D2D) networks, peer-to-peer (P2P) networks, vehicle-to-vehicle (V2V) networks, vehicle-to-everything (V2X) networks, and / or other suitable sidelink networks. For example, two or more UEs (e.g., UEs 238, 240, and 242) may communicate with each other using sidelink signals 237 without relaying the communications through a base station. In some examples, UEs 238, 240, and 242 may each act as a scheduling entity or a transmitting sidelink device and / or a scheduled entity or a receiving sidelink device to schedule resources and communicate sidelink signals 237 therebetween without relying on scheduling or control information from a base station. In other examples, two or more UEs (e.g., UEs 226 and 228) within the coverage area of ​​a base station (e.g., base station 212) may also communicate sidelink signals 227 on a direct link (sidelink) without communicating the communications through base station 212. In this example, base station 212 may allocate resources to UEs 226 and 228 for sidelink communications.

[0062] In the radio access network 200, the ability of a UE to communicate independently of its location while moving is called mobility. The various physical channels between the UE and the radio access network are typically managed by an access and mobility management function (AMF, not illustrated). Figure 1 The AMF is established, maintained and released under the control of the core network 102 in the core network, which may include a security context management function (SCMF) that manages the security context of both the control plane and the user plane functionalities and a security anchor function (SEAF) that performs authentication.

[0063] The radio access network 200 can utilize either DL-based mobility or UL-based mobility to implement mobility and handover (i.e., the transfer of a UE's connection from one radio channel to another). In a network configured for DL-based mobility, during a call with a scheduling entity, or at any other time, a UE can monitor various parameters of the signal from its serving cell and various parameters of neighboring cells. Depending on the quality of these parameters, the UE can maintain communication with one or more neighboring cells. During this time, if the UE moves from one cell to another, or if the signal quality from a neighboring cell exceeds the signal quality from the serving cell for a given amount of time, the UE can perform a handover or handover from the serving cell to the neighboring (target) cell. For example, a UE 224 (illustrated as a vehicle, but any suitable form of UE may be used) can move from the geographic area corresponding to its serving cell 202 to the geographic area corresponding to the neighboring cell 206. When the signal strength or quality from neighbor cell 206 exceeds the signal strength or quality of serving cell 202 for a given amount of time, UE 224 may transmit a report message indicating this condition to its serving base station 210. In response, UE 224 may receive a handover command, and the UE may undergo a handover to cell 206.

[0064] In a network configured for UL-based mobility, the UL reference signal from each UE can be used by the network to select a serving cell for each UE. In some examples, base stations 210, 212, and 214 / 216 can broadcast unified synchronization signals (e.g., a unified primary synchronization signal (PSS), a unified secondary synchronization signal (SSS), and a unified physical broadcast channel (PBCH)). UEs 222, 224, 226, 228, 230, and 232 can receive the unified synchronization signals, derive carrier frequency and slot timing from these synchronization signals, and transmit uplink pilots or reference signals in response to the derived timing. The uplink pilot signal transmitted by a UE (e.g., UE 224) can be received concurrently by two or more cells (e.g., base stations 210 and 214 / 216) within the radio access network 200. Each of these cells may measure the strength of the pilot signal, and the radio access network (e.g., one or more of base stations 210 and 214 / 216 and / or a central node within the core network) may determine a serving cell for UE 224. As UE 224 moves within radio access network 200, the network may continue to monitor the uplink pilot signals transmitted by UE 224. When the signal strength or quality of the pilot signal measured by a neighboring cell exceeds the signal strength or quality measured by the serving cell, network 200 may handover UE 224 from the serving cell to the neighboring cell with or without notifying UE 224.

[0065] Although the synchronization signal transmitted by base stations 210, 212, and 214 / 216 may be uniform, the synchronization signal may not identify a specific cell, but may identify a zone including multiple cells operating on the same frequency and / or having the same timing. The use of zones in 5G networks or other next-generation communication networks implements an uplink-based mobility framework and improves the efficiency of both the UE and the network because the number of mobility messages that need to be exchanged between the UE and the network can be reduced.

[0066] In various implementations, the air interface in the radio access network 200 may utilize licensed spectrum, unlicensed spectrum, or shared spectrum. Licensed spectrum generally provides exclusive use of a portion of the spectrum by a mobile network operator purchasing a license from a government regulator. Unlicensed spectrum provides shared use of a portion of the spectrum without the need for a government-granted license. While generally still subject to some technical regulations to access unlicensed spectrum, any operator or device may gain access. Shared spectrum may fall between licensed and unlicensed spectrum, where technical regulations or restrictions may be required to access the spectrum, but the spectrum may still be shared by multiple operators and / or multiple radio access technologies (RATs). For example, a license holder of a portion of licensed spectrum may provide licensed shared access (LSA) to share that spectrum with other parties, e.g., with access obtained under conditions determined by the appropriate license holder.

[0067] The electromagnetic spectrum is typically subdivided into various classes, bands, channels, etc. based on frequency / wavelength. In 5G NR, two initial operating bands have been identified as frequency range designations FR1 (410 MHz–7.125 GHz) and FR2 (24.25 GHz–52.6 GHz). It should be understood that although a portion of FR1 is greater than 6 GHz, FR1 is often (interchangeably) referred to as the “sub-6 GHz” band in various documents and articles. Similar naming issues sometimes arise with respect to FR2, which is often (interchangeably) referred to as the “millimeter wave” band in various documents and articles, although it is different from the extremely high frequency (EHF) band (30 GHz–300 GHz) identified as the “millimeter wave” band by the International Telecommunication Union (ITU).

[0068] Frequencies between FR1 and FR2 are generally referred to as mid-band frequencies. Recent 5G NR research has identified the operating bands of these mid-band frequencies as frequency range designation FR3 (7.125 GHz–24.25 GHz). The frequency bands falling within FR3 can inherit FR1 characteristics and / or FR2 characteristics, and thus can effectively extend the features of FR1 and / or FR2 to mid-band frequencies. Additionally, higher frequency bands are currently being explored to extend 5G NR operation to above 52.6 GHz. For example, three higher operating bands have been identified as frequency range designations FR4-a or FR4-1 (52.6 GHz–71 GHz), FR4 (52.6 GHz–114.25 GHz), and FR5 (114.25 GHz–300 GHz). Each of these higher frequency bands falls within the EHF band.

[0069] In view of the above aspects, unless otherwise specified, it should be understood that the terms "sub-6 GHz" and the like, if used herein, may broadly refer to frequencies that may be less than 6 GHz, may be within FR1, or may include mid-band frequencies. Furthermore, unless otherwise specified, it should be understood that the terms "millimeter wave" and the like, if used herein, may broadly refer to frequencies that may include mid-band frequencies, may be within FR2, FR4, FR4-a or FR4-1 and / or FR5, or may be within the EHF band.

[0070] The air interface in the radio access network 200 may utilize one or more multiplexing and multiple access algorithms to enable simultaneous communication of various devices. For example, the 5G NR specification utilizes orthogonal frequency division multiplexing (OFDM) with a cyclic prefix (CP) to provide multiple access for UL transmissions from UEs 222 and 224 to the base station 210, and provides multiplexing for DL ​​transmissions from the base station 210 to one or more UEs 222 and 224. In addition, for UL transmissions, the 5G NR specification provides support for discrete Fourier transform spread OFDM (DFT-s-OFDM) with CP (also known as single carrier FDMA (SC-FDMA)). However, within the scope of the present disclosure, multiplexing and multiple access are not limited to the above schemes and may be provided using time division multiple access (TDMA), code division multiple access (CDMA), frequency division multiple access (FDMA), sparse code multiple access (SCMA), resource spread multiple access (RSMA), or other appropriate multiple access schemes. Furthermore, multiplexing of DL transmissions from base station 210 to UEs 222 and 224 may be provided using time division multiplexing (TDM), code division multiplexing (CDM), frequency division multiplexing (FDM), orthogonal frequency division multiplexing (OFDM), sparse code multiplexing (SCM), or other suitable multiplexing schemes.

[0071] The air interface in the radio access network 200 may further utilize one or more duplexing algorithms. Duplexing refers to a point-to-point communication link in which both endpoints can communicate with each other in both directions. Full-duplexing means that both endpoints can communicate with each other simultaneously. Half-duplexing means that only one endpoint can send information to the other endpoint at a time. Half-duplex emulation is typically achieved for wireless links using time division duplexing (TDD). In TDD, transmissions in different directions on a given channel are separated from each other using time division multiplexing. That is, at some times, the channel is dedicated to transmission in one direction, while at other times, the channel is dedicated to transmission in the other direction, where the direction can change very quickly, for example, several times per time slot. In wireless links, full-duplex channels generally rely on physical isolation between the transmitter and receiver, as well as appropriate interference cancellation techniques. Full-duplex emulation is typically achieved for wireless links using frequency division duplexing (FDD) or space division duplexing (SDD). In FDD, transmissions in different directions operate at different carrier frequencies. In SDD, transmissions in different directions on a given channel are separated from each other using spatial division multiplexing (SDM). In other examples, full-duplex communication can be achieved within an unpaired spectrum (e.g., within a single carrier bandwidth), where transmissions in different directions occur within different sub-bands of the carrier bandwidth. This type of full-duplex communication may be referred to as sub-band full-duplex (SBFD), also known as flexible duplexing.

[0072] Various aspects of the present disclosure will be described with reference to OFDM waveforms, examples of which are shown in Figure 3 Schematically illustrated in FIG. Those skilled in the art will appreciate that various aspects of the present disclosure may be applied to SC-FDMA waveforms in substantially the same manner as described below. That is, while some examples of the present disclosure may focus on OFDM links for clarity, it will be appreciated that the same principles may also be applied to SC-FDMA waveforms.

[0073] Now refer to Figure 3 , illustrates an expanded view of an example subframe 302 showing an OFDM resource grid. However, as those skilled in the art will readily appreciate, the physical (PHY) layer transmission structure for any particular application may differ from the examples described herein depending on any number of factors. Here, time is in the horizontal direction in units of OFDM symbols; and frequency is in the vertical direction in units of subcarriers of a carrier.

[0074] Resource grid 304 can be used to schematically represent the time-frequency resources for a given antenna port. That is, in a multiple-input, multiple-output (MIMO) implementation with multiple antenna ports available, a corresponding plurality of resource grids 304 may be available for communication. Resource grid 304 is divided into a plurality of resource elements (REs) 306. An RE (which is 1 subcarrier x 1 symbol) is the smallest discrete portion of the time-frequency grid and contains a single complex value representing data from a physical channel or signal. Depending on the modulation utilized in a particular implementation, each RE may represent one or more information bits. In some examples, a block of REs may be referred to as a physical resource block (PRB) or more simply as a resource block (RB) 308, which may contain any suitable number of contiguous subcarriers in the frequency domain. In one example, an RB may include 12 subcarriers, independent of the parameter design used. In some examples, depending on the parameter design, an RB may include any suitable number of contiguous OFDM symbols in the time domain. Within this disclosure, it is assumed that a single RB (such as RB 308) corresponds entirely to a single communication direction (transmission or reception for a given device).

[0075] A set of contiguous or non-contiguous resource blocks may be referred to herein as a resource block group (RBG), subband, or bandwidth part (BWP). A set of subbands or BWPs may span the entire bandwidth. Scheduling a scheduled entity (e.g., a UE) for downlink, uplink, or sidelink transmission typically involves scheduling one or more resource elements 306 within one or more subbands or bandwidth parts (BWPs). Thus, a UE typically utilizes only a subset of resource grid 304. In some examples, an RB may be the smallest unit of resource that can be allocated to a UE. Thus, the more RBs scheduled for a UE and the higher the modulation scheme selected for the air interface, the higher the data rate for that UE. RBs may be scheduled by a scheduling entity, such as a base station (e.g., gNB, eNB, etc.), or may be self-scheduled by the UE implementing D2D sidelink communication.

[0076] In this illustration, RB 308 is shown as occupying less than the entire bandwidth of subframe 302, with some subcarriers illustrated above and below RB 308. In a given implementation, subframe 302 may have a bandwidth corresponding to any number of one or more RBs 308. Furthermore, in this illustration, RB 308 is shown as occupying less than the entire duration of subframe 302, but this is merely one possible example.

[0077] Each 1ms subframe 302 may include one or more adjacent time slots. As an illustrative example, Figure 3In the example shown in , a subframe 302 includes four time slots 310. In some examples, a time slot may be defined according to a specified number of OFDM symbols with a given cyclic prefix (CP) length. For example, with a nominal CP, a time slot may include 7 or 14 OFDM symbols. Additional examples may include mini-slots (sometimes referred to as shortened transmission time intervals (TTIs)) with shorter durations (e.g., one to three OFDM symbols). In some cases, these mini-slots or shortened transmission time intervals (TTIs) may be transmitted using resources scheduled for ongoing time slot transmissions for the same or different UEs. Any number of resource blocks may be utilized within a subframe or time slot.

[0078] The expanded view of one time slot 310 illustrates the time slot 310 including a control region 312 and a data region 314. Generally speaking, the control region 312 may carry control channels, while the data region 314 may carry data channels. Of course, a time slot may contain all DL, all UL, or at least one DL portion and at least one UL portion. Figure 3 The structure illustrated in is merely an example, and different slot structures may be utilized, and may include one or more for each of the control region and the data region.

[0079] Although not in Figure 3 Although not illustrated in FIG, each RE 306 within an RB 308 may be scheduled to carry one or more physical channels, including a control channel, a shared channel, a data channel, etc. Other REs 306 within an RB 308 may carry pilot or reference signals. These pilot or reference signals may be used by a receiving device to perform channel estimation for the corresponding channel, which may enable coherent demodulation / detection of the control and / or data channels within the RB 308.

[0080] In some examples, time slot 310 may be used for broadcast, multicast, groupcast, or unicast communications. For example, broadcast, multicast, or groupcast communications may refer to point-to-multipoint transmissions from one device (e.g., a base station, UE, or other similar device) to other devices. Here, broadcast communications are delivered to all devices, while multicast or groupcast communications are delivered to multiple intended recipient devices. Unicast communications may refer to point-to-point transmissions from one device to a single other device.

[0081] In the example of cellular communication over a cellular carrier via a Uu interface, for downlink transmissions, a scheduling entity (e.g., a base station) may allocate one or more REs 306 (e.g., within a control region 312) to carry downlink control information, including one or more downlink control channels (such as a physical downlink control channel (PDCCH)), to one or more scheduled entities (e.g., UEs). The PDCCH carries downlink control information (DCI), including, but not limited to, power control commands (e.g., one or more open-loop power control parameters and / or one or more closed-loop power control parameters) for downlink and uplink transmissions, scheduling information, grants, and / or RE assignments. The PDCCH may further carry hybrid automatic repeat request (HARQ) feedback transmissions, such as acknowledgements (ACKs) or negative acknowledgements (NACKs). HARQ is a technique well known to those skilled in the art, wherein the integrity of packet transmissions may be verified on the receiving side for accuracy, for example, using any suitable integrity check mechanism, such as a checksum or cyclic redundancy check (CRC). If the integrity of the transmission is confirmed, an ACK may be transmitted, while if it is not, a NACK may be transmitted. In response to the NACK, the transmitting device may send a HARQ retransmission, which may enable chase combining, incremental redundancy, and the like.

[0082] The base station may further allocate one or more REs 306 (e.g., in the control region 312 or the data region 314) to carry other DL signals, such as a demodulation reference signal (DMRS); a phase tracking reference signal (PT-RS); a channel state information (CSI) reference signal (CSI-RS); and a synchronization signal block (SSB). The SSB may be broadcast at regular intervals based on a periodicity (e.g., 5, 10, 20, 30, 80, or 130 milliseconds). The SSB includes a primary synchronization signal (PSS), a secondary synchronization signal (SSS), and a physical broadcast control channel (PBCH). The UE may utilize the PSS and SSS to achieve radio frame, subframe, slot, and symbol synchronization in the time domain, identify the center of the channel (system) bandwidth in the frequency domain, and identify the physical cell identity (PCI) of the cell.

[0083] The PBCH in the SSB may further include: a master information block (MIB), which includes various system information and parameters for decoding the system information block (SIB). The SIB may be, for example, system information type 1 (SystemInformationType1) (SIB1), which may include various additional (remaining) system information. The MIB and SIB1 together provide minimum system information (SI) for initial access. Examples of system information transmitted in the MIB may include, but are not limited to: subcarrier spacing (e.g., default downlink parameter design), system frame number, configuration of the PDCCH control resource set (CORESET) (e.g., PDCCH CORESET0), cellular cell barring indicator, cellular cell reselection indicator, raster offset, and search space for SIB1. Examples of remaining minimum system information (RMSI) transmitted in SIB1 may include, but are not limited to, random access search space, paging search space, downlink configuration information, and uplink configuration information. The base station may also transmit other system information (OSI).

[0084] In an UL transmission, a scheduled entity (e.g., a UE) may utilize one or more REs 306 to carry UL control information (UCI) to a scheduling entity, the UL control information comprising one or more UL control channels, such as a physical uplink control channel (PUCCH). UCI may include various packet types and categories, including pilots, reference signals, and information configured to enable or assist in decoding uplink data transmissions. Examples of uplink reference signals may include sounding reference signals (SRS) and uplink DMRS. In some examples, UCI may include a scheduling request (SR), i.e., a request for a scheduling entity to schedule an uplink transmission. Here, in response to the SR transmitted on the UCI, the scheduling entity may transmit downlink control information (DCI), which may schedule resources for uplink packet transmission. UCI may also include HARQ feedback, channel state feedback (CSF) (such as a CSI report), or any other suitable UCI.

[0085] In addition to control information, one or more REs 306 (e.g., within the data region 314) may also be allocated for data traffic. Such data traffic may be carried on one or more traffic channels, such as the physical downlink shared channel (PDSCH) for DL ​​transmissions or the physical uplink shared channel (PUSCH) for UL transmissions. In some examples, one or more REs 306 within the data region 314 may be configured to carry other signals, such as one or more SIBs and DMRS.

[0086] In an example of sidelink communication on a sidelink carrier via a Proximity Service (ProSe) PC5 interface, the control region 312 of a time slot 310 may include a physical sidelink control channel (PSCCH), which includes sidelink control information (SCI) transmitted by an initiator (transmitter) sidelink device (e.g., a transmitter (Tx) V2X device or other Tx UE) to a set of one or more other receiver sidelink devices (e.g., a receiver (Rx) V2X device or some other Rx UE). The data region 314 of the time slot 310 may include a physical sidelink shared channel (PSSCH), which includes sidelink data traffic transmitted by the initiator (transmitter) sidelink device within resources reserved by the transmitter sidelink device on the sidelink carrier via the SCI. Other information may further be transmitted on each RE 306 within the time slot 310. For example, HARQ feedback information may be transmitted from the receiving side link device to the transmitting side link device in a physical sidelink feedback channel (PSFCH) within time slot 310. Additionally, one or more reference signals, such as a sidelink SSB, a sidelink CSI-RS, a sidelink SRS, and / or a sidelink positioning reference signal (PRS), may be transmitted within time slot 310.

[0087] These physical channels are typically multiplexed and mapped onto transport channels for processing by the Medium Access Control (MAC) layer. Transport channels carry blocks of information, referred to as transport blocks (TBs). The transport block size (TBS), which may correspond to the number of information bits, may be a controlled parameter based on the modulation and coding scheme (MCS) and the number of RBs in a given transmission.

[0088] Refer to above Figures 1 to 3 The channels or carriers described in are not necessarily all of the channels or carriers that can be utilized between the scheduling entity and the scheduled entity, and one of ordinary skill in the art will recognize that other channels or carriers can be utilized in addition to those channels or carriers illustrated, such as other traffic, control, and feedback channels.

[0089] 5G-NR networks may support carrier aggregation (CA) of component carriers (CCs) transmitted from different cells and / or different transmit reception points (TRPs) in a multi-cell transmission environment. Different TRPs may be associated with a single serving cell or multiple serving cells. In some aspects, the term component carrier (CC) may refer to a carrier frequency (or frequency band) used for communications within a cell.

[0090] Figure 44 is a diagram illustrating a multi-cell transmission environment 400 according to some aspects. The multi-cell transmission environment 400 includes a primary serving cell (PCell) 402 and one or more secondary serving cells (SCells) 406a, 406b, 406c, and 406d. PCell 402 may be referred to as an anchor cell that provides a radio resource control (RRC) connection to a UE (e.g., UE 410).

[0091] When carrier aggregation is configured in a multi-cell transmission environment 400, one or more of the SCells 406a-406d can be activated or added to the PCell 402 to form a serving cell serving the UE 410. In this case, each serving cell corresponds to a component carrier (CC). The CC of the PCell 402 can be referred to as a primary CC, while the CCs of the SCells 406a-406d can be referred to as secondary CCs. In some examples, the UE 410 can correspond to Figure 1 、 2 , any of the UEs or scheduled entities shown in any of 5, 6, 9 and 10.

[0092] Each of the PCell 402 and SCells 406a-406d may be served by a Transmission Reception Point (TRP). For example, the PCell 402 may be served by the TRP 404, while each of the SCells 406a-406c may be served by a corresponding TRP 408a-408c. Each TRP 404 and 408a-408c may be a base station (e.g., a gNB), a remote radio head of a gNB, or a TRP associated with the base station. Figure 1 、 2 , 5, 6 and 9. In some examples, PCell 402 and one or more SCells (e.g., SCell 406d) can be co-located. For example, the TRP of PCell 402 and the TRP of SCell 406 can be installed at the same geographical location. Thus, in some examples, a TRP (e.g., TRP 404) can include multiple TRPs, each TRP corresponding to one of multiple co-located antenna arrays, and each TRP supports a different carrier (different CC). However, the coverage of PCell 402 and SCell 406d may be different because component carriers in different frequency bands may experience different path losses and thereby provide different coverage.

[0093] The PCell 402 is responsible not only for connection establishment but also for radio resource management (RRM) and radio link monitoring (RLM) of the connection with the UE 410. For example, the PCell 402 may activate one or more SCells (e.g., SCell 406a) for multi-cell communication with the UE 410 to improve the reliability of the connection to the UE 410 and / or increase the data rate. In some examples, the PCell may activate the SCell 406a as needed, rather than maintaining the SCell activated when the SCell 406a is not used for data transmission / reception, to reduce power consumption of the UE 410.

[0094] In some examples, PCell 402 may be a low-band cell, while SCell 406 may be a high-band cell. A low-band (LB) cell uses CCs in a lower frequency band than a high-band cell. For example, the high-band cells may each use a corresponding millimeter wave CC (e.g., FR2 or higher), while the low-band cell may use a CC in a lower frequency band (e.g., a sub-6 GHz band or FR1). Generally speaking, cells using FR2 or higher CCs can provide greater bandwidth than cells using FR1 CCs. In addition, when using carriers with frequencies above 6 GHz (e.g., millimeter wave), beamforming can be used to transmit and receive signals.

[0095] In some examples, PCell 402 can utilize a first radio access technology (RAT), such as LTE, and one or more SCells 406 can utilize a second RAT, such as 5G-NR. In this example, the multi-cell transmission environment can be referred to as a multi-RAT-dual connectivity (MR-DC) environment. An example of MR-DC is the Evolved Universal Terrestrial Radio Access Network-New Radio Dual Connectivity (EN-DC) mode, which enables a UE to simultaneously connect to an LTE base station and an NR base station to receive data packets from both the LTE base station and the NR base station and to send data packets to both the LTE base station and the NR base station.

[0096] Figure 5 An example of a wireless communication system 500 is illustrated in which a UE 502 can operate in EN-DC mode. The wireless communication system 500 includes a first core network 504 (e.g., an LTE network) and a second core network 506 (e.g., an NR network), and potentially other networks (not shown). In some examples, the UE 502 can correspond to Figure 1 、 2 , any of the UEs or scheduled entities shown in any of 4, 6, 9 and 10.

[0097] For the EN-DC mode, the UE 502 is connected to the eNB 508 of the first core network 504 via signaling 510 (e.g., LTE signaling, sub-6 signaling, etc.). In this example, the eNB 508 serves as the master node in the EN-DC mode. In some examples, the eNB 508 may correspond to Figure 1 , 2 , any one of the base stations or scheduling entities shown in any of 4, 6, and 9.

[0098] The UE 502 is also connected to the gNB 512 of the second core network 506 via signaling 514 (e.g., NR signaling, millimeter wave signaling, etc.). In this example, the gNB 512 serves as the secondary node in the EN-DC operating mode. In some examples, the gNB 512 may correspond to Figure 1 , 2 , any one of the base stations or scheduling entities shown in any of 4, 6, and 9.

[0099] A given UE may have specific capabilities. For example, the UE may support communication over a bandwidth range up to a certain maximum bandwidth. As another example, the UE may support communication via one or more MIMO layers up to a maximum number of MIMO layers. In some aspects, one or more of these limitations may be due to the baseband processing capabilities and / or other processing capabilities of the UE.

[0100] In the EN-DC scenario, the baseband processing of the UE may support a specific combination of MIMO layers and bandwidth. For example, the UE may support up to a certain number of LTE layers and up to a certain aggregated bandwidth for NR.

[0101] The following are two examples of such UE capabilities. In these examples, the terms L1, L2, and L3 refer to different numbers of MIMO layers. As a non-limiting example, L1 may be 10 layers, L2 may be 20 layers, and L3 may be 30 layers. Thus, L1 < L2 < L3 layers. Different numbers of layers may be supported in other examples.

[0102] Also in the following examples, the term NR envelope in some aspects refers to the processing capability of the UE to support communication via one or more frequency bands. For example, the term NR envelope in some aspects may refer to the throughput capability of the UE for NR communication.

[0103] In the first example of UE capabilities, the terms B1, B2, and B3 refer to different bandwidths. As a non-limiting example, B1 may be 40 MHz, B2 may be 100 MHz, and B3 may be 200 MHz. Thus, B1 < B2 < B3 MHz bandwidth. Other sub-6 bandwidths may be supported in other examples.

[0104] In this first example, the UE may support LTE L1 layer + B3 MHz NR sub-6 TDD (which may be referred to as the maximum NR envelope). Additionally, the UE may support LTE L3 layer + B1 MHz NR sub-6 TDD (which may be referred to as the 1 / 2 NR envelope). However, in this example, the UE does not support LTE L3 layer + B3 MHz NR sub-6 TDD.

[0105] In the second example of UE capabilities, the terms B100, B200, and B300 refer to different bandwidths. As a non-limiting example, B100 may be 200 MHz, B200 may be 400 MHz, and B300 may be 600 MHz. Thus, B100 < B200 < B300 MHz bandwidths. Other millimeter-wave bandwidths may be supported in other examples.

[0106] In this second example, the UE may support LTE L1 layer + B300 MHz NR mmW (maximum NR envelope). Additionally, the UE may support LTE L3 layer + B100 MHz NR mmW (1 / 2 NR envelope). However, in this example, the UE does not support LTE L3 layer + B300 MHz NR mmW.

[0107] If the network configures the UE with an EN-DC band combination, in some examples it may be desirable for the network to allocate to the UE the maximum NR bandwidth supported by the UE. The network may then allocate the LTE layer to the UE based on the declared UE capabilities (e.g., the band combinations described in the two examples above).

[0108] Figure 6 is a diagram illustrating an example of signaling 600 associated with network configuration of a UE in a wireless communication network including a base station (BS) 602 and a user equipment (UE) 604. In some examples, BS602 may correspond to Figure 1 the scheduling entity 108, or Figure 2 one or more of the base stations 210, 212, 214, or 216 of Figure 1 the scheduled entity 106 (e.g., a UE, etc.) of Figure 2 one or more of the UEs 222, 224, 226, 228, 230, 232, 234, 238, 240, or 242 of Figure 4 the UE 410 of Figure 5 one or more of the UEs 502 of

[0109] In Figure 6At 606, UE 604 may initiate a registration procedure with BS 602 to gain access to the network served by BS 602. For example, UE 604 may perform an initial cell search by detecting a PSS from BS 602 (e.g., a PSS of a cell of BS 602). The PSS may enable UE 604 to synchronize to the periodic timing of BS 602 and may indicate a physical layer identity value assigned to the cell. UE 604 may also receive an SSS from BS 602 that enables UE 604 to synchronize to the cell at the radio frame level. The SSS may also provide a cell identity value, which UE 604 may combine with the physical layer identity value to identify the cell.

[0110] UE 604 may then receive the MIB and SIB broadcast by BS 602 (e.g., as discussed above) to obtain information related to random access channel (RACH) procedures, physical channels, etc. For example, SIB1 provides scheduling information and / or the availability of other SIB types and / or information (e.g., public land mobile network (PLMN) information and / or cell barring information) that may guide the UE in performing cell selection and / or cell reselection. After obtaining the SI, UE 604 may perform a random access procedure to initiate an RRC connection with BS 602.

[0111] At 608, BS 602 may request capability information from UE 604. For example, BS 602 may transmit a UE capability query to UE 604 (eg, via an RRC message).

[0112] At 610, UE 604 may transmit its capability information to BS 602. For example, UE 604 may transmit a UE capability message to BS 602 (e.g., via an RRC message).

[0113] At 612, BS 602 can transmit an RRC configuration to UE 604 (e.g., in conjunction with completing the connection setup with UE 604). In some examples, the RRC configuration can specify resources (e.g., number of layers and / or bandwidth) for UE 604 to use when accessing one or more cells of the network.

[0114] In some scenarios, the network may not allocate resources to the UE in a preferred manner. For example, the RRC configuration of 612 may not fully consider the capability information of the UE 604 (from step 610).

[0115] As a specific example, the UE may announce that it supports both 1 / 2 NR and Maximum NR envelope band combinations, as discussed above. The following are two example scenarios for allocating resources in a suboptimal manner for this example network.

[0116] In the first scenario (Case 1), the network may only be able to provide a B1 MHz allocation. Thus, in this scenario, the network can only support NR up to a maximum of B1 MHz. In a sub-scenario of Case 1 (Sub-case P1), the network may configure the UE based solely on checking the maximum NR envelope band combination. In this scenario, the network may only configure the UE with the minimum number of LTE layers (e.g., L1 layers) instead of the maximum number of layers (e.g., L3 layers) that the UE can support. For example, the network may configure the UE with L1 layers for LTE + B1 MHz for NR. This may result in a lower throughput than the UE can support.

[0117] In the second scenario (Case 2), the network may be able to provide a B3 MHz allocation. Thus, in this scenario, the network can support NR up to a maximum of B3 MHz.

[0118] In the first sub-scenario of Case 2 (Sub-case P1), the network may misconfigure the UE with the maximum NR bandwidth and the maximum number of LTE layers, which is a configuration that the UE does not support. For example, the network may configure the UE with L3 layers for LTE + B3 MHz for NR.

[0119] In the second sub-scenario of Case 2 (Sub-case P2), the network may configure the UE with a 1 / 2 NR envelope (e.g., the network may prioritize assigning the maximum number of LTE layers). For example, the network may configure the UE with L3 layers for LTE + B1 MHz for NR. This may result in a lower throughput than the UE can support.

[0120] Possible problems in Situation 1 and Situation 2 and other configuration issues will be referred to Figure 7 and 8 To describe. Figure 7 Referring to the first example UE capability discussed above, Figure 8 This relates to the second example UE capability discussed above.

[0121] Figure 7 Illustrated is an example of a network configuration 700 for a UE in an example scenario. The network configuration 700 can, for example, be used for the first example UE capability discussed above (eg, where the UE can support L1 / L2 / L3 and B1 / B2 / B3).

[0122] The network configures the UE with L3 layers for LTE in an initial LTE standalone (SA) configuration 702. Subsequently, the network may configure the UE for EN-DC or some other dual connectivity configuration.

[0123] In a potential subsequent configuration 704, the network may attempt to configure the UE with B3 MHz TDD for NR (e.g., in case 2, subcase P1 discussed above). Since the UE does not support this configuration, the UE may reject the NR configuration.

[0124] In an alternative potential subsequent configuration 706, the network may attempt to configure the UE with B1 MHz TDD for NR instead of B3 MHz TDD for NR. Thus, configuration 706 is an example of scenario 2, sub-scenario P2, discussed above. The UE supports this configuration; however, if the network is capable of supporting B3 MHz for NR, this configuration may be suboptimal. On the other hand, if the network is capable of supporting only B1 MHz for NR, this configuration may be acceptable.

[0125] In another alternative potential subsequent configuration 708, the network may downgrade LTE by configuring the UE to have L1 layer for LTE and B3 MHz TDD for NR. The UE supports this configuration and thus this may be the preferred configuration.

[0126] In a potential subsequent configuration 710, the network may further downgrade NR by configuring the UE to have L1 layers for LTE and B1 MHz TDD for NR (e.g., as in scenario 1, sub-case P1 discussed above). The UE supports this configuration, but it may be suboptimal (e.g., if the network is able to support an upgraded LTE configuration).

[0127] Figure 8 Illustrated is an example of a network configuration 800 for a UE in another example scenario. Network configuration 800 can, for example, be used for the second example UE capability discussed above (eg, where the UE can support L1 / L2 / L3 and B100 / B200 / B300).

[0128] The network configures the UE with L3 layers for LTE in an initial LTE standalone (SA) configuration 802. Subsequently, the network may configure the UE for EN-DC or some other dual connectivity configuration.

[0129] In a potential subsequent configuration 804, the network may also attempt to configure the UE with B300 MHz for NR (e.g., as in scenario 2, sub-case P1 discussed above). Since the UE does not support this configuration, the UE may reject the NR configuration.

[0130] In an alternative potential subsequent configuration 806, the network may attempt to configure the UE with B1 MHz for NR instead of B3 MHz for NR. Thus, configuration 706 is an example of scenario 2, sub-scenario P2, discussed above. The UE supports this configuration; however, if the network is capable of supporting B3 MHz for NR, this configuration may be suboptimal. On the other hand, if the network is only capable of supporting B100 MHz for NR, this configuration may be acceptable.

[0131] In another alternative potential subsequent configuration 808, the network may downgrade LTE by configuring the UE to have L1 layer for LTE and B3 MHz for NR. The UE supports this configuration and thus this may be the preferred configuration.

[0132] In a potential subsequent configuration 810, the network may further downgrade NR by configuring the UE to have L1 layers for LTE and B1 MHz for NR (e.g., as in scenario 1, sub-case P1 discussed above). The UE supports this configuration, but it may be suboptimal (e.g., if the network is able to support an upgraded LTE configuration).

[0133] The present disclosure, in some aspects, relates to steering the network towards a preferred combination (e.g., for the current network market) based on one or more of PLMN, frequency band, tracking area identifier (TAI), or geographic location. Below are two examples of different networks for Scenario 1, Sub-Scenario P1, and Scenario 2, Sub-Scenario P2 (described above), where a UE can advertise a 1 / 2NR or maximum NR envelope band combination based on the network the UE is currently in.

[0134] In a first example network that supports B1 MHz or less for an NR band (e.g., in the UK market), the UE may broadcast the capability of only 1 / 2 NR envelope mode for band combinations involving that NR band (e.g., the UE disables maximum NR). This may result in the UE announcing L3 layer + B1 MHz TDD. However, the UE will not announce L1 layer + B3 MHz TDD. In some aspects, this can resolve potential issues with the Case 1, Subcase P1 scenario discussed above.

[0135] In a second example network that supports B1 MHz or higher for an NR band (e.g., in the German market), the UE may broadcast the capability of the maximum NR envelope mode for band combinations involving that NR band (e.g., the UE disables 1 / 2NR). This may result in the UE announcing L1 layer + B3 MHz TDD. However, the UE will not announce L3 layer + B1 MHz TDD. In some aspects, this may involve potential issues with the scenario 2, sub-case P2 scenario discussed above.

[0136] The UE's capability declaration can be based on information collected by the UE from various resources. Examples of such resources can include crowdsourcing, fingerprinting, and static provisioning. For example, the UE can access a crowdsourcing server or one or more other entities to share and obtain information that each UE has collected regarding services provided by different networks over time (e.g., layer, bandwidth, etc.) and / or the successful and unsuccessful configurations of the network for the UE. At the same time, the UE can implement fingerprinting (e.g., data collection over time) to obtain information regarding services provided by different networks over time and / or the previous successful / unsuccessful configurations of different networks for the UE. Additionally, the UE can be statically configured (e.g., at the time of deployment) with information regarding services provided by different networks. Each of these crowdsourcing, fingerprinting, and static provisioning techniques can be performed per PLMN, per TAI, per geographical location, per frequency, per frequency band, etc.

[0137] This disclosure relates in some aspects to guiding the UE towards an effective band combination that the network is capable of configuring. For example, for Scenario 2, Sub-Scenario P1 discussed above, the UE can keep track (e.g., per PLMN) of the most recent unique EN-DC envelope (and associated NR band) that provided a successful network connection (e.g., the most recent 10 configurations with the following data for each entry: <PLMN, NR band, NR envelope>).

[0138] In the case where the network misconfigures the UE to have an unsupported envelope (e.g., B3MHz BW on NR band Nx, and L3 layer in LTE), but includes the effective NR bandwidth declared by the UE, the UE can take the following actions. If the current failure is the k-th occurrence (e.g., for a specific PLMN, TAI, geographical location, or combination thereof), the UE can update its network restriction list (e.g., <PLMN, envelope restriction list>) or some other capability rule to include only 1 / 2NR or the maximum NR envelope that was previously successful). The above entries can be retained in non-volatile memory across power cycles and deleted after a certain amount of time (e.g., in the case where the network fixes the problem).

[0139] The above solution can be extended to use cloud services (e.g., network servers), where each UE reports the successful or unsuccessful band combination configurations from each network. The UE can then query the cloud service to identify which band combinations the UE should declare based on the band combinations that have been successful for other devices (e.g., other UEs).

[0140] This disclosure relates in some aspects to adapting the configuration of the network to the capabilities of the UE. The following are three examples.

[0141] In the first example (Solution 1), if the network's configuration exceeds the envelope supported by the UE (e.g., Case 2, Subcase P1), the UE may attempt to reduce the number of configured LTE layers. For example, the UE may accept an RRC reconfiguration from the network that exceeds the UE's envelope. However, the UE may report a channel quality indicator (CQI) below a certain threshold on certain LTE SCells (e.g., reporting CQI=0) to cause the network to stop scheduling data on these LTE SCells. In this way, the UE may cause the network to configure the UE within the UE's envelope limits.

[0142] In a second example (Solution 2), on NR, the UE may use a message to reduce the number of component carriers (CCs) and / or the aggregate bandwidth configured by the network (Case 2, Subcase P1). For example, the UE may send a UE Assistance Information message (e.g., which may be referred to as a UEAssistanceInformation message) to request the network to release the SCell on the NR to reduce the aggregate bandwidth configured for the UE.

[0143] In a third example (Solution 3), the UE may force the network to add NR bandwidth instead of LTE component carriers (CCs) and / or layers. Here, the UE may monitor and / or estimate the throughput that the UE may require to support specific communications. If the UE anticipates that the future throughput of the UE will need to be relatively high or if the current throughput is already relatively high, the UE may send a message (e.g., a UEAssistanceInformation message) requesting the network to reduce the number of configured LTE layers. This may be done before sending NR measurements to the NR network (e.g., if certain measurement criteria are met). Thus, the UE may cause the network to add more NR bandwidth instead of LTE CCs / layers in this scenario.

[0144] The present disclosure relates in some aspects to adapting announced UE capabilities based on network segmentation. Some networks may have a segmented deployment. For example, a network (e.g., a PLMN) may allocate B100 MHz in some areas and B300 MHz in other areas.

[0145] The present disclosure relates in some aspects to dynamic radio capability update functionality in scenarios where network segmentation exists. The UE may build a knowledge base of which areas (e.g., based on GPS location, TAI list, cell ID, frequency, band, or a combination thereof) have B100 MHz deployments and which areas have B300 MHz deployments (or some other deployment). This knowledge base may be maintained within the UE and / or may be based on a cloud service.

[0146] When the UE moves to a different area, the UE may initiate a registration procedure indicating that a radio capability update is required (e.g., to comply with segmentation). When the network sends a UE capability query, the UE may send an updated band combination list (including only 1 / 2 NR envelopes or only the maximum NR envelope) based on the current area. If both the UE and the network support radio capability signaling (RACS), the UE can use a service request procedure to switch between different UE radio capabilities (e.g., U1 and U2). This service request procedure eliminates the need for the UE to wait for the network to send a UE capability query and thereby incur a large amount of over-the-air (OTA) signaling.

[0147] The present disclosure relates in some aspects to dynamic updating (e.g., switching) between different UE radio capability IDs (URCIDs). As mentioned above, a UE can use a service request procedure to dynamically indicate which UE radio capability ID (URCID) to use. In an example scenario, a UE has URCIDs U1 and U2 assigned by the network through different registration procedures performed in the past. Each URCID corresponds to a different radio capability setting on the UE. For example, U1 may correspond to UE capability information containing a certain list of frequency band combinations (e.g., the first example UE capability discussed above), and U2 may correspond to UE capability information containing a different list of frequency band combinations (e.g., the second example UE capability discussed above).

[0148] In a registration request, the UE may send URCID U1. Subsequently, upon a service request, depending on the region, the UE may potentially request a handover to URCID U2. Upon the next service request, depending on the region, the UE may potentially request a handover back to U1. A URCID may be a short pointer with a defined format that uniquely identifies a set of UE radio capabilities (e.g., UE radio capability information). The UE radio capability ID may be assigned by the serving PLMN or, in some examples, by the UE manufacturer.

[0149] Figure 9 is a signaling diagram 900 illustrating an example of signaling associated with user equipment capabilities in a wireless communication system including a base station (BS) 902 and a user equipment (UE) 904. In some examples, the BS 902 may correspond to Figure 1 、 2 , 4, 5 and 6. In some examples, UE 904 may correspond to any of the base stations or scheduling entities shown in any of . Figure 1 、 2 , any of the UEs or scheduled entities shown in any of 4, 5, 6 and 10.

[0150] exist Figure 9906, UE 904 can be configured (e.g., pre-configured) with information that UE 904 can use for network access. For example, the UE can be configured (e.g., when the UE is activated by a carrier) with information related to the PLMN, TAI, and frequency band that UE 904 can use for network access. Additionally, in some examples, UE 904 can be pre-configured with one or more URCIDs (as discussed above).

[0151] At 908, UE 904 may collect information about various networks over time. For example, as UE 904 connects to different networks, UE 904 may collect information about these connections. As another example, UE 904 may connect to a crowdsourcing server or other device to obtain network information collected by other UEs over time. Such collected information may include, for example, resources supported by different networks (e.g., layers, bandwidth, frequency band combinations, etc.), successful resource configurations of the networks, unsuccessful resource configurations of the networks, network segmentation, and the like, as discussed herein.

[0152] At some point in time, UE 904 may attempt to connect to a network served by BS 902, at 910. For example, UE 904 may receive a signal from BS 902 identifying the network (e.g., identifying an associated PLMN), as discussed herein.

[0153] At 912, the UE 904 may select at least one capability to announce to the BS 902 based on the information collected by the UE 904 at 908. For example, the UE 904 may select a set of capabilities to announce to the BS 902 based on layer, bandwidth, and frequency band combinations supported by the network, based on successful / unsuccessful resource configuration of the network, etc., as discussed herein. In some examples, the UE 904 may select a set of capabilities that will prevent the BS 902 from misconfiguring the UE 904.

[0154] At 914, UE 904 may transmit one or more capabilities selected at 912 and / or transmit other information to BS 902. Examples of other information that UE 904 may transmit include messages attempting to prevent misconfiguration of the network (e.g., reporting CQI=0, transmitting UE assistance information messages, etc.).

[0155] At 916, BS 902 may configure UE 904 based on the capability message of 914. For example, BS 902 may transmit an RRC configuration message to UE 904 that specifies the number of layers and bandwidth for UE 904 to use.

[0156] Figure 10 10 is a block diagram illustrating an example of a hardware implementation of a UE 1000 employing a processing system 1014. For example, the UE 1000 may be a device configured to wirelessly communicate with a base station, such as in Figures 1-9 In some implementations, the UE 1000 may correspond to Figure 1 、 2 , any of the UEs or scheduled entities shown in any of 4, 5, 6 and 9.

[0157] According to various aspects of the present disclosure, an element, or any portion of an element, or any combination of elements may be implemented using a processing system 1014. The processing system 1014 may include one or more processors 1004. Examples of processors 1004 include microprocessors, microcontrollers, digital signal processors (DSPs), field programmable gate arrays (FPGAs), programmable logic devices (PLDs), state machines, gated logic, discrete hardware circuits, and other suitable hardware configured to perform the various functionalities described throughout this disclosure. In various examples, the UE 1000 may be configured to perform any one or more of the functions described herein. That is, the processor 1004, as utilized in the UE 1000, may be used to implement any one or more of the processes and procedures described herein.

[0158] In some examples, the processor 1004 may be implemented via a baseband or modem chip, while in other implementations, the processor 1004 may include several devices distinct and separate from the baseband or modem chip (e.g., which in such scenarios may work together to achieve the examples discussed herein). As mentioned above, various hardware arrangements and components outside of the baseband modem processor may be used in implementations, including RF chains, power amplifiers, modulators, buffers, interleavers, adders / summers, etc.

[0159] In this example, the processing system 1014 may be implemented using a bus architecture generally represented by bus 1002. Depending on the specific application and overall design constraints of the processing system 1014, the bus 1002 may include any number of interconnecting buses and bridges. The bus 1002 communicatively couples various circuits including one or more processors (generally represented by processor 1004), memory 1005, and computer-readable media (generally represented by computer-readable media 1006). The bus 1002 may also link various other circuits, such as timing sources, peripherals, voltage regulators, and power management circuits, which are well known in the art and will not be described further. The bus interface 1008 provides an interface between the bus 1002 and the transceiver 1010 and antenna array 1020, as well as between the bus 1002 and the interface 1030. The transceiver 1010 provides a communication interface or means for communicating with various other equipment over a wireless transmission medium. Interface 1030 provides a communication interface or means for communicating with various other devices and equipment (e.g., other devices housed in the same device as the UE or other external devices) over an internal bus or external transmission medium (e.g., an Ethernet cable). Depending on the characteristics of the equipment, interface 1030 may include a user interface (e.g., a keypad, display, speaker, microphone, joystick). Of course, such a user interface is optional and may be omitted in some examples (e.g., IoT devices).

[0160] The processor 1004 is responsible for managing the bus 1002 and general processing, including the execution of software stored on a computer-readable medium 1006. The software, when executed by the processor 1004, causes the processing system 1014 to perform the various functions described below for any particular implementation. The computer-readable medium 1006 and the memory 1005 may also be used to store data manipulated by the processor 1004 when executing the software. For example, the memory 1005 may store configuration information 1015 that the processor 1004 uses for the communication operations described herein.

[0161] One or more processors 1004 in the processing system can execute software. Software should be construed broadly to mean instructions, instruction sets, code, code segments, program code, programs, subroutines, software modules, applications, software applications, software packages, routines, subroutines, objects, executables, threads of execution, procedures, functions, etc., whether referred to as software, firmware, middleware, microcode, hardware description language, or other terms. The software may reside on a computer-readable medium 1006.

[0162] Computer-readable medium 1006 may be a non-transitory computer-readable medium. By way of example, non-transitory computer-readable media include magnetic storage devices (e.g., hard disks, floppy disks, magnetic tapes), optical disks (e.g., compact discs (CDs) or digital versatile discs (DVDs)), smart cards, flash memory devices (e.g., card, stick, or key-type drives), random access memory (RAM), read-only memory (ROM), programmable ROM (PROM), erasable PROM (EPROM), electrically erasable PROM (EEPROM), registers, removable disks, and any other suitable medium for storing software and / or instructions that can be accessed and read by a computer. Computer-readable medium 1006 may reside in processing system 1014, be external to processing system 1014, or be distributed across multiple entities including processing system 1014. Computer-readable medium 1006 may be embodied in a computer program product. By way of example, a computer program product may include a computer-readable medium in packaging material. Those skilled in the art will recognize how to best implement the described functionality presented throughout this disclosure depending on the specific application and the overall design constraints imposed on the overall system.

[0163] UE 1000 may be configured to perform any one or more operations described herein (e.g., as described above in conjunction with Figures 1-9 Described and combined as follows Figure 11-14 In some aspects of the present disclosure, the processor 1004, as utilized in the UE 1000, may include circuitry configured for various functions.

[0164] Processor 1004 may include communication and processing circuitry 1041. Communication and processing circuitry 1041 may be configured to communicate with a base station (such as a gNB). Communication and processing circuitry 1041 may include one or more hardware components that provide a physical structure for performing various processes associated with wireless communication (e.g., signal reception and / or signal transmission) as described herein. Communication and processing circuitry 1041 may further include one or more hardware components that provide a physical structure for performing various processes associated with signal processing (e.g., processing received signals and / or processing signals for transmission) as described herein. In some examples, communication and processing circuitry 1041 may include two or more transmit / receive chains. Communication and processing circuitry 1041 may be further configured to execute communication and processing software 1051 included on computer-readable medium 1006 to implement one or more functions described herein.

[0165] In some implementations where communication involves receiving information, communication and processing circuitry 1041 may obtain information from a component of UE 1000 (e.g., from transceiver 1010 that receives information via radio frequency signaling or some other type of signaling suitable for the applicable communication medium), process (e.g., decode) the information, and output the processed information. For example, communication and processing circuitry 1041 may output the information to another component of processor 1004, to memory 1005, or to bus interface 1008. In some examples, communication and processing circuitry 1041 may receive one or more of a signal, a message, other information, or any combination thereof. In some examples, communication and processing circuitry 1041 may receive information via one or more channels. In some examples, communication and processing circuitry 1041 may include functionality of a means for receiving. In some examples, communication and processing circuitry 1041 may include functionality of a means for decoding.

[0166] In some implementations where communication involves sending (e.g., transmitting) information, communication and processing circuitry 1041 may obtain information (e.g., from another component of processor 1004, memory 1005, or bus interface 1008), process (e.g., encode) the information, and output the processed information. For example, communication and processing circuitry 1041 may output the information to transceiver 1010 (e.g., transmitting the information via radio frequency signaling or some other type of signaling appropriate for the applicable communication medium). In some examples, communication and processing circuitry 1041 may send one or more of a signal, a message, other information, or any combination thereof. In some examples, communication and processing circuitry 1041 may send information via one or more channels. In some examples, communication and processing circuitry 1041 may include functionality of a means for sending (e.g., a means for transmitting). In some examples, communication and processing circuitry 1041 may include functionality of a means for encoding.

[0167] Processor 1004 may include configuration processing circuitry 1042 configured to perform operations related to configuration processing as discussed herein. Configuration processing circuitry 1042 may be configured to execute configuration processing software 1052 included on computer-readable medium 1006 to implement one or more functions described herein.

[0168] The configuration processing circuitry 1042 may include functionality of means for determining bandwidths supported by a network (e.g., a network within a particular country, region, etc.). For example, the configuration processing circuitry 1042 may be configured to identify a first network (or segment of a network) based on a PLMN, a frequency band, etc., and to identify a bandwidth supported by the first network (e.g., by accessing a local database or a remote server, such as a cloud-based server).

[0169] Configuration processing circuitry 1042 may include functionality for determining that a network has misconfigured resources for a user equipment. For example, configuration processing circuitry 1042 may be configured to receive a configuration from the network (e.g., via an RRC message) and determine whether the configuration is consistent with the capabilities of the user equipment.

[0170] The configuration processing circuitry 1042 may include functionality for generating a message to cause the network to reconfigure at least one resource. For example, the configuration processing circuitry 1042 may be configured to generate a request for the network to reduce the number of LTE MIMO layers configured for the user equipment. As another example, the configuration processing circuitry 1042 may be configured to generate a UE assistance information message.

[0171] Configuration processing circuitry 1042 may include functionality for identifying a region. For example, configuration processing circuitry 1042 may be configured to receive a signal from a network or another source (e.g., a location information signal from a GPS satellite) to identify a PLMN, cell ID, frequency band, etc.

[0172] Processor 1004 may include capability selection circuitry 1043 configured to perform operations related to capability selection as discussed herein. Capability selection circuitry 1043 may be further configured to execute capability selection software 1053 included on computer-readable medium 1006 to implement one or more functions described herein.

[0173] The capability selection circuitry 1043 may include functionality for selecting a means for processing capabilities. For example, the capability selection circuitry 1043 may be configured to identify UE capabilities (e.g., L3 layer and B1 MHz, etc.) that do not exceed a bandwidth supported by the network (e.g., B1 MHz, etc.). As another example, the capability selection circuitry 1043 may be configured to remove any capability combinations corresponding to unsuccessful configurations of the network from the capability rules (or list).

[0174] The capability selection circuitry 1043 may comprise functionality of means for transmitting an indication of processing capabilities.For example, the capability selection circuitry 1043 may be configured to announce the capabilities of the user equipment (eg, by transmitting a UE capabilities message).

[0175] The capability selection circuitry 1043 may include functionality for maintaining an indication of processing capabilities. For example, the capability selection circuitry 1043 may be configured to update a list of successful and unsuccessful configurations (e.g., by accessing a local database or a remote server, such as a cloud-based server).

[0176] Figure 11 is a flow chart illustrating an example method 1100 for wireless communication according to some aspects. As described below, some or all of the illustrated features may be omitted in certain implementations within the scope of the present disclosure, and some of the illustrated features may not be required to implement all examples. In some examples, the method 1100 may be performed by Figure 10 The user equipment 1000 illustrated in the figure may be executed by any suitable equipment or device for implementing the functions or algorithms described below.

[0177] At block 1102, a user equipment may determine a first bandwidth supported by a first network for a first radio access technology (RAT). Figure 10 The configuration processing circuitry 1042 shown and described (optionally in cooperation with the communication and processing circuitry 1041 and the transceiver 1010) may provide means for determining a first bandwidth supported by a first network for a first radio access technology (RAT). In some examples, the first RAT may include a Third Generation Partnership Project (3GPP) New Radio (NR) technology.

[0178] In some examples, determining by the user equipment a first bandwidth for a first RAT supported by a first network (e.g., supported by a base station of the network) may include identifying a public land mobile network (PLMN) announced by the first network and identifying a bandwidth associated with the PLMN. In some examples, determining by the user equipment a first bandwidth for a first RAT supported by the first network may include identifying a radio frequency (RF) band of the first network and identifying a bandwidth associated with the RF band. In some examples, determining by the user equipment a first bandwidth for a first RAT supported by the first network may include identifying a tracking area identifier (TAI) announced by the first network and identifying a bandwidth associated with the TAI. In some examples, determining by the user equipment a first bandwidth for a first RAT supported by the first network may include identifying a location of the user equipment and identifying a bandwidth associated with the location.

[0179] In some examples, determining by the user equipment a first bandwidth for the first RAT supported by the first network may include retrieving information indicating the first bandwidth from a server. In some examples, determining by the user equipment a first bandwidth for the first RAT supported by the first network may include collecting information indicating the first bandwidth based on multiple accesses of the user equipment to the first network. In some examples, determining by the user equipment a first bandwidth for the first RAT supported by the first network may include retrieving defined information indicating the first bandwidth from a memory of the user equipment.

[0180] In some examples, the first bandwidth is for a sub-6 GHz frequency band. In some examples, the first bandwidth is for a millimeter wave (mmW) frequency band.

[0181] At block 1104, the user equipment may select a first processing capability of the user equipment from among a plurality of processing capabilities based on a first bandwidth for a first RAT supported by a first network. Figure 10 The capability selection circuitry 1043 shown and described may provide means for selecting a first processing capability from a plurality of processing capabilities of a user equipment based on (e.g., based on determining) a first bandwidth for a first RAT supported by a first network.

[0283] Within this disclosure, the word "exemplary" is used to mean "serving as an example, instance, or illustration." Any implementation or aspect described herein as "exemplary" is not necessarily to be construed as superior or preferable to other aspects of the disclosure. Likewise, the term "aspect" does not require that all aspects of the disclosure include the feature, advantage, or mode of operation discussed. The term "coupled" is used herein to refer to a direct or indirect coupling between two objects. For example, if object A physically contacts object B, and object B contacts object C, objects A and C may still be considered to be coupled to each other—even if they are not in direct physical contact with each other. For example, a first object may be coupled to a second object even if the first object is never in direct physical contact with the second object. The terms "circuit" and "circuitry" are used broadly and are intended to include both hardware implementations of electronic devices and conductors that, when connected and configured, enable the functions described in this disclosure to be performed without limitation on the type of electronic circuitry, and software implementations of information and instructions that, when executed by a processor, enable the functions described in this disclosure to be performed. As used herein, the term "determining" may include, for example, ascertaining, resolving, selecting, choosing, establishing, computing, calculating, processing, deriving, investigating, searching (e.g., searching in a table, database, or other data structure), and the like. Furthermore, "determining" may include receiving (e.g., receiving information), accessing (e.g., accessing data in a memory), and the like.

[0284] Figures 1 to 14 One or more of the components, steps, features, and / or functions described herein may be rearranged and / or combined into a single component, step, feature, or function, or may be implemented in several components, steps, or functions. Additional elements, components, steps, and / or functions may also be added without departing from the novel features disclosed herein. Figure 1 、 2 The equipment, devices and / or components illustrated in , 4, 5, 6, 9 and 10 may be configured to perform one or more of the methods, features, or steps described herein. The novel algorithms described herein may also be efficiently implemented in software and / or embedded in hardware.

[0285] It should be understood that the specific order or hierarchy of steps in the disclosed methods is illustrative of example processes. Based on design preferences, it will be understood that the specific order or hierarchy of steps in these methods may be rearranged. The accompanying method claims present elements of the various steps in a sample order and are not meant to be limited to the specific order or hierarchy presented unless specifically recited herein.

[0286] The preceding description is provided to enable anyone skilled in the art to practice the various aspects described herein. Various modifications to these aspects will be readily apparent to those skilled in the art, and the universal principles defined herein may be applied to other aspects. Accordingly, the claims are not intended to be limited to the aspects shown herein, but rather should be granted the full scope consistent with the claim language, with references to elements in the singular not intended to mean "one and only one" unless specifically stated otherwise, but rather "one or more." Unless specifically stated otherwise, the term "some" refers to one or more. A phrase referring to "at least one of" a list of items refers to any combination of those items, including individual members. By way of example, "at least one of a, b, or c" is intended to encompass: a; b; c; a and b; a and c; b and c; and a, b, and c. All structural and functional equivalents of the elements described in the various aspects of this disclosure, now or hereafter known to those skilled in the art, are expressly incorporated herein by reference and are intended to be covered by the claims. Furthermore, nothing disclosed herein is intended to be dedicated to the public, regardless of whether such disclosure is explicitly stated in the claims.
