[0002] This patent application claims priority to Greek Patent Application No. 20200100691, filed on November 20, 2020, entitled “NETWORK-CONTROLLED DISABLING OF USER EQUIPMENT(UE)RADIO CAPABILITIES”, which has been assigned to its assignee and is expressly incorporated herein by reference. Technical Field
[0003] The following discussion pertains to wireless communications, including network control disabling of user equipment (UE) radio capabilities. Background Technology
[0004] Wireless communication systems are widely deployed to provide various types of communication content, such as voice, video, packet data, messaging, and broadcasting. These systems can support communication with multiple users by sharing available system resources (e.g., time, frequency, and power). Examples of such multiple access systems include fourth-generation (4G) systems such as Long Term Evolution (LTE), Advanced LTE (LTE-A), or LTE-APro systems, and fifth-generation (5G) systems, which may be referred to as New Radio (NR) systems. These systems can employ technologies such as Code Division Multiple Access (CDMA), Time Division Multiple Access (TDMA), Frequency Division Multiple Access (FDMA), Orthogonal Frequency Division Multiple Access (OFDMA), or Discrete Fourier Transform Extended Orthogonal Frequency Division Multiplexing (DFT-S-OFDM). A wireless multiple access communication system may include one or more base stations or one or more network access nodes, each of which simultaneously supports communication from multiple communication devices, which may also be referred to as User Equipment (UE).
[0005] In some wireless communication systems, a UE can support communication with the network (e.g., via a base station) using multiple radio capabilities (e.g., 4G capabilities, 5G capabilities, Evolved Packet System (EPS) capabilities, Narrowband Internet of Things (NB-IoT) capabilities, or other supported radio capabilities). In some cases, the UE's communication based on one or more radio capabilities can be restricted, such as based on the UE's subscription. However, in some examples, the UE can autonomously reselect to communicate based on restricted radio capabilities, or be instructed by the network, and the network can subsequently refuse the UE's communication based on restricted radio capabilities. Therefore, the UE may experience greater latency and power loss due to attempting to communicate based on restricted radio capabilities. Summary of the Invention
[0006] The described technology relates to improved methods, systems, devices, and apparatuses for supporting network-controlled disabling of user equipment (UE) radio capabilities. Typically, the described technology is used to prevent a UE from attempting to communicate based on restricted radio capabilities. For example, some UEs may support multiple radio capabilities and may communicate based on one or more supported radio capabilities. In some examples, a UE supporting multiple radio capabilities may establish a connection with (e.g., register with) a network (e.g., a core network). During registration, the UE may send a UE capability message indicating the set of radio capabilities supported by the UE. The network may receive the UE capability message (e.g., via a base station) and may identify subscription information associated with the UE, which includes one or more radio capabilities restricted to the UE. Based on the subscription information, the network may apply a filter to the set of radio capabilities to remove one or more restricted radio capabilities from the set. The network may send a message to the UE including a radio capability modification indication indicating one or more restricted radio capabilities and a UE radio capability identifier corresponding to the filtered set of radio capabilities. The UE may receive the message and may identify the network-restricted radio capabilities based on the message. The UE can disable one or more restricted radio capabilities based on the radio capability modification indication, and can communicate with the network based on one or more radio capabilities (e.g., unrestricted radio capabilities) from the filtered radio capability set.

[0047] Some wireless communication systems may include communication devices, such as user equipment (UE) and base stations, which may support multiple radio capabilities, such as fourth-generation (4G) (e.g., Long Term Evolution (LTE)) and fifth-generation (5G) (e.g., New Radio (NR)) capabilities, as well as other radio capabilities. In some examples, a UE can communicate with the network via a base station according to a first radio capability and can autonomously reselect to communicate according to a second radio capability, or be instructed by the network to do so. However, in some cases, the UE's communication according to the second radio capability may be restricted based on its subscription. For example, the UE's use of the LTE system may be restricted based on its subscription; however, since the UE is able to communicate using the LTE system and is unaware of the restriction, it may attempt to reselect to the LTE system. The network may then refuse the UE's reselection to the LTE system and, in some cases, may allocate a timer to prevent the UE from attempting to reselect to the LTE system for a period of time. Therefore, attempting to reselect to a system corresponding to a restricted radio capability may increase latency, channel overhead, and power loss due to the unnecessary increase in signaling between the UE and the network.
[0048] This document describes technologies, systems, and devices for instructing a UE to specify restricted radio capabilities to prevent the UE from attempting to reselect to restricted radio capabilities. For example, a UE supporting multiple radio capabilities may establish a connection with (e.g., register with) a network (e.g., a core network). During registration, the UE may send a UE capability message indicating the set of radio capabilities it supports. The network (e.g., a network device or other network entity) may receive the UE capability message (e.g., via a base station) and may identify subscription information associated with the UE, which includes one or more radio capabilities restricted to the UE. The network may use the subscription information to determine a radio capability modification indication indicating one or more restricted radio capabilities and to determine the UE's UE radio capability identifier. The UE radio capability identifier may correspond to an unrestricted subset of the radio capability set. The network may send a message to the UE indicating the UE radio capability identifier and the radio capability modification indication (e.g., a Non-Access Stratum (NAS) message).
[0049] The UE can communicate with the network based on one or more radio capabilities from a subset of radio capabilities. For example, the UE can receive messages and disable one or more restricted radio capabilities. The UE can select a radio access technology (RAT) or system corresponding to the enabled radio capabilities and can use the selected RAT or system to communicate with the network. Additionally or alternatively, the UE can use a RAT or system to communicate with the network and can avoid reselecting to a RAT or system corresponding to one or more restricted radio capabilities based on a received radio capability modification indication.
[0050] The aspects of the subject matter described in this disclosure can be implemented to achieve, in particular, one or more of the following potential improvements. The technology employed by the UE can bring benefits and enhancements to the operation of the UE. For example, operations performed by the UE can improve mobility management operations. In some examples, receiving an indication of restricted radio capabilities from the network can prevent the UE from attempting to communicate based on the restricted radio capabilities. In some other examples, the network indicating restricted radio capabilities can provide improvements in latency, power consumption, spectral efficiency, and in some examples can contribute to achieving highly reliable communication, among other benefits.
[0051] The aspects of this disclosure are initially described in the context of a wireless communication system. Then, the aspects of this disclosure are described in the context of a process flow. The aspects of this disclosure are further illustrated and described in conjunction with apparatus diagrams, system diagrams, and flowcharts relating to network control disabling of UE radio capabilities.
[0052] Figure 1 An example of a network-controlled disabled wireless communication system 100 supporting UE radio capabilities according to various aspects of this disclosure is illustrated. The wireless communication system 100 may include one or more base stations 105, one or more UEs 115, and a core network 130. In some examples, the wireless communication system 100 may be an LTE network, an LTE-A Advanced (LTE-A) network, an LTE-APro network, or an NR network. In some examples, the wireless communication system 100 may support enhanced broadband communication, ultra-reliable (e.g., mission-critical) communication, low-latency communication, communication with low-cost and low-complexity devices, or any combination thereof.
[0053] Base stations 105 can be distributed throughout a geographical area to form a wireless communication system 100, and can be devices of different forms or with different capabilities. Base stations 105 and UE 115 can communicate wirelessly via one or more communication links 125. Each base station 105 can provide a coverage area 110, and UE 115 and base station 105 can establish one or more communication links 125 over the coverage area. Coverage area 110 can be an example of a geographical area over which base station 105 and UE 115 can support signal communication according to one or more RATs.
[0054] UE 115 can be distributed throughout the entire coverage area 110 of the wireless communication system 100, and each UE 115 can be fixed or mobile, or fixed or mobile at different times. UE 115 can be devices of different forms or with different capabilities. Figure 1Some example UE 115s are shown in the document. The UE 115 described herein may be able to communicate with various types of devices, such as other UE 115s, base station 105, or network devices (e.g., core network nodes, relay devices, integrated access and backhaul (IAB) nodes, or other network devices), such as... Figure 1 As shown.
[0055] Base station 105 can communicate with core network 130, communicate with each other, or both. For example, base station 105 can interface with core network 130 via one or more backhaul links 120 (e.g., via S1, N2, N3, or other interfaces). Base station 105 can communicate with each other directly (e.g., directly between base stations 105) or indirectly (e.g., via core network 130) or both via backhaul links 120 (e.g., via X2, Xn, or other interfaces). In some examples, backhaul link 120 can be or includes one or more radio links.
[0056] One or more of the base stations 105 described herein may include, or may be referred to by those skilled in the art as, base station transceiver, radio base station, access point, radio transceiver, NodeB, eNodeB (eNB), next-generation NodeB or giga-NodeB (any of which may be referred to as gNB), home NodeB, home eNodeB or other suitable terms.
[0057] UE 115 may include or be referred to as a mobile device, wireless device, remote device, handheld device, or subscriber device, or some other suitable term, wherein "device" may also be referred to as a unit, station, terminal, or client. UE 115 may also include or be referred to as a personal electronic device such as a cellular phone, personal digital assistant (PDA), tablet computer, laptop computer, or personal computer. In some examples, UE 115 may include or be referred to as a wireless local loop (WLL) station, Internet of Things (IoT) device, Internet of Everything (IoE) device, or machine-type communication (MTC) device, among other examples, which can be implemented in a variety of objects, such as appliances, vehicles, meters, and other examples.
[0058] The UE 115 described in this document may be able to communicate with various types of devices, such as other UEs 115 that may sometimes act as relays, as well as base station 105 and network devices including macro eNBs or gNBs, small cell eNBs or gNBs, or relay base stations, etc. Figure 1 As shown.
[0059] UE 115 and base station 105 can wirelessly communicate with each other via one or more communication links 125 on one or more carriers. The term "carrier" can refer to a set of radio spectrum resources having a defined physical layer structure for supporting communication link 125. For example, a carrier for communication link 125 may include a portion (e.g., bandwidth portion (BWP)) of a radio frequency spectrum band that operates for a given RAT (e.g., LTE, LTE-A, LTE-APro, NR) according to one or more physical layer channels. Each physical layer channel may carry acquisition signaling (e.g., synchronization signals, system information), control signaling coordinating operations for the carrier, user data, or other signaling. Wireless communication system 100 can support communication with UE 115 using carrier aggregation or multi-carrier operation. UE 115 can be configured with multiple downlink component carriers and one or more uplink component carriers according to a carrier aggregation configuration. Carrier aggregation can be used for both frequency division duplex (FDD) and time division duplex (TDD) component carriers.
[0060] In some examples (e.g., in a carrier aggregation configuration), a carrier may also have acquisition or control signaling to coordinate the operation of other carriers. A carrier may be associated with a frequency channel (e.g., an Evolved Universal Mobile Telecommunications System Terrestrial Radio Access (E-UTRA) Absolute Radio Frequency Channel Number (EARFCN)) and can be located according to a channel grating for discovery by the UE 115. A carrier may operate in standalone mode, where initial acquisition and connection can be performed by the UE 115 via the carrier, or the carrier may operate in non-standalone mode, where the connection is anchored using different carriers (e.g., the same or different RATs).
[0061] The communication link 125 shown in the wireless communication system 100 may include uplink transmission from UE 115 to base station 105, or downlink transmission from base station 105 to UE 115. The carrier may carry downlink or uplink communication (e.g., in FDD mode), or may be configured to carry both downlink and uplink communication (e.g., in TDD mode).
[0062] The signal waveform transmitted via a carrier can consist of multiple subcarriers (e.g., using multi-carrier modulation (MCM) techniques, such as orthogonal frequency division multiplexing (OFDM) or discrete Fourier transform extended OFDM (DFT-S-OFDM)). In a system employing MCM, a resource element can include a symbol period (e.g., the duration of a modulation symbol) and a subcarrier, where the symbol period and subcarrier spacing are inversely related. The number of bits carried by each resource element can depend on the modulation scheme (e.g., the order of the modulation scheme, the coding rate of the modulation scheme, or both). Therefore, the more resource elements the UE 115 receives and the higher the order of the modulation scheme, the higher the data rate the UE 115 can potentially achieve. Wireless communication resources can refer to a combination of radio spectrum resources, temporal resources, and spatial resources (e.g., spatial layers or beams), and the use of multiple spatial layers can further improve the data rate or data integrity for communication with the UE 115.
[0063] The time interval of base station 105 or UE 115 can be expressed as a multiple of a basic time unit, for example, the basic time unit can refer to T. s =1 / (Δf) max ·N f The sampling period is ) seconds, where Δf max This can represent the maximum supported subcarrier spacing, and N f It can represent the maximum supported Discrete Fourier Transform (DFT) size. The time intervals of communication resources can be organized according to radio frames, each with a specified duration (e.g., 10 milliseconds (ms)). Each radio frame can be identified by its System Frame Number (SFN) (e.g., ranging from 0 to 1023).
[0064] Each frame may include multiple consecutively numbered subframes or time slots, and each subframe or time slot may have the same duration. In some examples, a frame may be divided (e.g., in the time domain) into subframes, and each subframe may be further divided into multiple time slots. Alternatively, each frame may include a variable number of time slots, and the number of time slots may depend on the subcarrier spacing. Each time slot may include multiple periods (e.g., depending on the length of the cyclic prefix preceding each symbol period). In some wireless communication systems 100, time slots may be further divided into multiple micro-time slots containing one or more symbols. In addition to the cyclic prefix, each symbol period may contain one or more (e.g., N) f (Number) sampling periods. The duration of a symbol period can depend on the subcarrier spacing or the operating frequency band.
[0065] A subframe, time slot, micro-time slot, or symbol can be the smallest scheduling unit of the wireless communication system 100 (e.g., in the time domain) and can be referred to as a transmission time interval (TTI). In some examples, the duration of the TTI (e.g., the number of symbol periods in the TTI) can be variable. Additionally or alternatively, the smallest scheduling unit of the wireless communication system 100 can be dynamically selected (e.g., in a burst of shortened TTIs (sTTIs)).
[0066] Physical channels can be multiplexed on a carrier using various techniques. For example, one or more of Time Division Multiplexing (TDM), Frequency Division Multiplexing (FDM), or hybrid TDM-FDM techniques can be used to multiplex physical control channels and physical data channels on a downlink carrier. A control region (e.g., a control resource set (CORESET)) for physical control channels can be defined by the number of symbol periods and can extend over the system bandwidth or a subset of the system bandwidth of the carrier. One or more control regions (e.g., CORESETs) can be configured for a set of UEs 115. For example, one or more UEs 115 can monitor or search for control regions for control information based on one or more search space sets, and each search space set can include one or more control channel candidates at one or more aggregation levels arranged in a cascaded manner. The aggregation level for control channel candidates can refer to the number of control channel resources (e.g., control channel elements (CCEs)) associated with coded information for a control information format having a given payload size. The search space set can include a common search space set configured to send control information to multiple UEs 115 and a UE-specific search space set for sending control information to a specific UE 115.
[0067] Each base station 105 may provide communication coverage via one or more cells (e.g., macro cells, small cells, hotspots, or other types of cells, or any combination thereof). The term "cell" may refer to a logical communication entity used to communicate with base station 105 (e.g., via a carrier) and may be associated with an identifier used to distinguish neighboring cells (e.g., Physical Cell Identifier (PCID), Virtual Cell Identifier (VCID), or other identifier). In some examples, a cell may also refer to a geographic coverage area 110 or a portion of geographic coverage area 110 (e.g., a sector) on which a logical communication entity operates. Depending on various factors such as the capabilities of base station 105, the extent of these cells can range from smaller areas (e.g., structures, subsets of structures) to larger areas. For example, a cell may be or include buildings, subsets of buildings, or external space between or overlapping geographic coverage areas 110, etc.
[0068] Macro cells typically cover a relatively large geographical area (e.g., a radius of several kilometers) and can allow unrestricted access to UE 115 with a service subscription from a network provider supporting the macro cell. In contrast, small cells can be associated with a lower-power base station 105 and can operate in the same or different (e.g., licensed, unlicensed) frequency bands as macro cells. Small cells can provide unrestricted access to UE 115 through a service subscription from a network provider, or restricted access to UE 115 associated with the small cell (e.g., UE 115 in a Closed Subscriber Group (CSG), UE 115 associated with a user in a home or office, etc.). Base station 105 can support one or more cells and can also support communication on one or more cells using one or more component carriers.
[0069] In some examples, a carrier can support multiple cells and can be configured with different cells based on different protocol types that can provide access for different types of devices (e.g., MTC, Narrowband IoT (NB-IoT), Enhanced Mobile Broadband (eMBB)).
[0070] In some examples, base station 105 may be mobile, and thus provide communication coverage for mobile geographic coverage areas 110. In some examples, different geographic coverage areas 110 associated with different technologies may overlap, but the different geographic coverage areas 110 may be supported by the same base station 105. In other examples, overlapping geographic coverage areas 110 associated with different technologies may be supported by different base stations 105. Wireless communication system 100 may include, for example, a heterogeneous network, in which different types of base stations 105 use the same or different RATs to provide coverage for various geographic coverage areas 110.
[0071] The wireless communication system 100 can support synchronous or asynchronous operation. For synchronous operation, base stations 105 can have similar frame timing, and transmissions from different base stations 105 can be approximately aligned in time. For asynchronous operation, base stations 105 can have different frame timing, and in some examples, transmissions from different base stations 105 can be misaligned in time. The techniques described herein can be used for both synchronous and asynchronous operation.
[0072] Some UE 115 devices (such as MTC or IoT devices) can be low-cost or low-complexity devices that can provide automated communication between machines (e.g., via machine-to-machine (M2M) communication). M2M communication or MTC can refer to data communication technologies that allow devices to communicate with each other or with base station 105 without human intervention. In some examples, M2M communication or MTC can include communication from devices that integrate sensors or meters to measure or capture information and forward such information to a central server or application that uses the information or presents it to humans interacting with the application. Some UE 115 devices can be designed to collect information or enable automated behavior of machines or other devices. Examples of applications for MTC devices include smart metering, inventory monitoring, water level monitoring, equipment monitoring, healthcare monitoring, wildlife monitoring, weather and geological event monitoring, fleet management and tracking, remote security sensing, physical access control, and transaction-based service charging.
[0073] Some UE 115s can be configured to operate in a power-saving mode, such as half-duplex communication (e.g., a mode that supports unidirectional communication via transmission or reception, but not simultaneous transmission and reception). In some examples, half-duplex communication may be performed at a reduced peak rate. Other power-saving techniques for UE 115s include entering a power-saving deep sleep mode when not engaged in active communication, operating on limited bandwidth (e.g., according to narrowband communication), or a combination of these techniques. For example, some UE 115s can be configured to operate using a narrowband protocol type associated with a defined portion or range (e.g., a set of subcarriers or RBs) within a carrier, within a carrier's guard band, or outside a carrier.
[0074] Wireless communication system 100 can be configured to support ultra-reliable communication or low-latency communication, or various combinations thereof. For example, wireless communication system 100 can be configured to support ultra-reliable low-latency communication (URLLC) or mission-critical communication. UE 115 can be designed to support ultra-reliable, low-latency, or mission-critical functions (e.g., mission-critical functions). Ultra-reliable communication can include private or group communication and can be supported by one or more mission-critical services (such as mission-critical key-touch (MCPTT), mission-critical video (MCVideo), or mission-critical data (MCData)). Support for mission-critical functions can include prioritization of services, which can be used for public safety or general business applications. The terms ultra-reliable, low-latency, mission-critical, and ultra-reliable low-latency are used interchangeably herein.
[0075] In some examples, UE 115 is also able to communicate directly with other UE 115 via device-to-device (D2D) communication link 135 (e.g., using peer-to-peer (P2P) or D2D protocols). One or more UE 115s utilizing D2D communication can be within the geographic coverage area 110 of base station 105. Other UE 115s in this group may be outside the geographic coverage area 110 of base station 105 or may not be able to receive transmissions from base station 105 in other ways. In some examples, the group of UE 115s communicating via D2D communication can utilize a one-to-many (1:M) system, where each UE 115 transmits to every other UE 115 in the group. In some examples, base station 105 facilitates the scheduling of resources for D2D communication. In other cases, D2D communication is performed between UE 115s without involving base station 105.
[0076] Core network 130 can provide user authentication, access authorization, tracking, Internet Protocol (IP) connectivity, and other access, routing, or mobility functions. Core network 130 can be an evolved packet core (EPC) or a 5G core (5GC), and can include at least one control plane entity (e.g., a mobility management entity (MME), access and mobility management function (AMF)) managing access and mobility, and at least one user plane entity routing packets or interconnects to external networks (e.g., a serving gateway (S-GW), a packet data network (PDN) gateway (P-GW), or a user plane function (UPF)). The control plane entity can manage non-access stratum (NAS) functions associated with core network 130 for UE 115 served by base station 105, such as mobility, authentication, and bearer management. User IP packets can be delivered through the user plane entity, which can provide IP address allocation and other functions. The user plane entity can connect to one or more network operator IP services 150. IP services 150 can include access to the Internet, intranets, IP Multimedia Subsystem (IMS), or packet-switched streaming services.
[0077] Some network devices, such as base station 105, may include sub-components such as access network entity 140, which may be an example of an access node controller (ANC). Each access network entity 140 may communicate with UE 115 through one or more other access network transmitting entities 145, which may be referred to as a radio headend, smart radio headend, or transmit / receive point (TRP). Each access network transmitting entity 145 may include one or more antenna panels. In some configurations, the various functions of each access network entity 140 or base station 105 may be distributed across various network devices (e.g., radio headends and ANCs) or combined into a single network device (e.g., base station 105).
[0078] Wireless communication system 100 can operate using one or more frequency bands, typically in the range of 300 MHz to 300 GHz. The region from 300 MHz to 3 GHz is generally referred to as the Ultra High Frequency (UHF) region or decimeter band because the wavelength range extends from approximately one decimeter to one meter in length. UHF waves may be blocked or redirected by buildings and environmental features; however, the waves may be sufficient to penetrate structures for use in macrocells to provide service to UE 115 located indoors. Compared to transmission using smaller frequencies and longer waves in the lower frequency (HF) or very high frequency (VHF) portions of the spectrum below 300 MHz, UHF wave transmission can be associated with smaller antennas and shorter distances (e.g., less than 100 km).
[0079] The wireless communication system 100 can also operate in the ultra-high frequency (SHF) region (also known as the centimeter band) using a frequency band from 3 GHz to 30 GHz, or in the extremely high frequency (EHF) region of the spectrum (e.g., from 30 GHz to 300 GHz) (also known as the millimeter band). In some examples, the wireless communication system 100 may support millimeter-wave (mmW) communication between the UE 115 and the base station 105, and the EHF antennas of the corresponding devices may be smaller and more closely spaced than UHF antennas. In some examples, this may facilitate the use of antenna arrays within the device. However, the propagation of EHF transmissions may suffer even greater atmospheric attenuation and a shorter range than SHF or UHF transmissions. The techniques disclosed herein can be employed across transmissions using one or more different frequency zonings, and the frequency band usage specified across these frequency zonings may vary by country or regulatory authority.
[0080] Wireless communication system 100 can utilize both licensed and unlicensed radio spectrum bands. For example, wireless communication system 100 can use Licensed Assisted Access (LAA), LTE Unlicensed (LTE-U) radio access technology, or NR technology in unlicensed bands such as the 5 GHz Industrial, Scientific, and Medical (ISM) band. When operating in unlicensed radio frequency spectrum bands, devices such as base station 105 and UE 115 can employ carrier sensing for collision detection and avoidance. In some examples, operation in unlicensed frequency bands can be based on carrier aggregation configurations (e.g., LAA) that combine component carriers operating in licensed bands. Operation in unlicensed spectrum can include downlink transmissions, uplink transmissions, P2P transmissions, or D2D transmissions, among other examples.
[0081] Base station 105 or UE 115 may be equipped with multiple antennas, which may be used to employ techniques such as transmit diversity, receive diversity, multiple-input multiple-output (MIMO) communication, or beamforming. The antennas of base station 105 or UE 115 may be located within one or more antenna arrays or antenna panels, which may support MIMO operation or transmit or receive beamforming. For example, one or more base station antennas or antenna arrays may be co-located at an antenna assembly such as an antenna tower. In some examples, the antennas or antenna arrays associated with base station 105 may be located in different geographical locations. Base station 105 may have an antenna array with multiple rows and columns of antenna ports, which base station 105 may use to support beamforming for communication with UE 115. Similarly, UE 115 may have one or more antenna arrays that may support various MIMO or beamforming operations. Additionally or alternatively, antenna panels may support radio frequency beamforming for signals transmitted via antenna ports.
[0082] By transmitting or receiving multiple signals via different spatial layers, base station 105 or UE 115 can use MIMO communication to leverage multipath signal propagation and improve spectral efficiency. This technique can be referred to as spatial multiplexing. For example, multiple signals can be transmitted by a transmitting device via different antennas or different combinations of antennas. Similarly, multiple signals can be received by a receiving device via different antennas or different combinations of antennas. Each of the multiple signals can be referred to as a separate spatial stream and can carry bits associated with the same data stream (e.g., the same codeword) or different data streams (e.g., different codewords). Different spatial layers can be associated with different antenna ports used for channel measurement and reporting. MIMO techniques include single-user MIMO (SU-MIMO) in which multiple spatial layers are transmitted to the same receiving device and multi-user MIMO (MU-MIMO) in which multiple spatial layers are transmitted to multiple devices.
[0083] Beamforming (also known as spatial filtering, directional transmission, or directional reception) is a signal processing technique that can be used at a transmitting or receiving device (e.g., base station 105 or UE 115) to form or guide an antenna beam (e.g., a transmit beam, a receive beam) along a spatial path between the transmitting and receiving devices. Beamforming can be achieved by combining signals transmitted via antenna elements of an antenna array such that some signals propagating relative to the antenna array in a particular direction undergo constructive interference, while others undergo destructive interference. Adjustments to the signals transmitted via the antenna elements may include the transmitting or receiving device applying amplitude shifts, phase shifts, or both to the signals carried via the antenna elements associated with that device. The adjustments associated with each antenna element can be defined by a set of beamforming weights associated with a particular direction (e.g., relative to the antenna array of the transmitting or receiving device, or relative to some other direction).
[0084] Base station 105 or UE 115 may use beam scanning technology as part of beamforming operations. For example, base station 105 may use multiple antennas or antenna arrays (e.g., antenna panels) to perform beamforming operations for directional communication with UE 115. Some signals (e.g., synchronization signals, reference signals, beam selection signals, or other control signals) may be transmitted multiple times by base station 105 in different directions. For example, base station 105 may transmit signals according to different beamforming weight sets associated with different transmission directions. Beam directions may be identified using transmissions in different beam directions (e.g., by a transmitting device such as base station 105, or by a receiving device such as UE 115) for later transmission or reception by base station 105.
[0085] Some signals (such as data signals associated with a specific receiving device) may be transmitted by base station 105 in a single beam direction (e.g., the direction associated with a receiving device such as UE 115). In some examples, the beam direction associated with transmission along a single beam direction may be determined based on the signals transmitted in one or more beam directions. For example, UE 115 may receive one or more signals transmitted by base station 105 in different directions and may report to base station 105 an indication of the signals received by UE 115 with the highest signal quality or other acceptable signal quality.
[0086] The wireless communication system 100 can be a packet-based network operating according to a layered protocol stack. In the user plane, communication at the bearer or packet data convergence protocol (PDCP) layer can be IP-based. The radio link control (RLC) layer can perform packet segmentation and reassembly for communication on logical channels. The media access control (MAC) layer can perform priority processing and multiplex logical channels into transport channels. The MAC layer can also use error detection techniques, error correction techniques, or both to support retransmissions at the MAC layer to improve link efficiency. In the control plane, the radio resource control (RRC) protocol layer can provide the establishment, configuration, and maintenance of RRC connections (which support radio bearers for user plane data) between the UE 115 and the base station 105 or core network 130. At the physical layer, transport channels can be mapped to physical channels.
[0087] UE 115 and base station 105 can support data retransmission to increase the likelihood of successful data reception. Hybrid Automatic Repeat Request (HARQ) feedback is a technique to increase the likelihood of correct data reception over communication link 125. HARQ can include a combination of error detection (e.g., using Cyclic Redundancy Check (CRC)), forward error correction (FEC), and retransmission (e.g., Automatic Repeat Request (ARQ)). HARQ can improve throughput at the MAC layer under poor radio conditions (e.g., low signal-to-noise ratio conditions). In some examples, the device can support same-slot HARQ feedback, where the device can provide HARQ feedback for data received in a previous symbol within a specific time slot. In other cases, the device can provide HARQ feedback in subsequent time slots or according to some other time interval.
[0088] UE 115 can support communication with base station 105 based on multiple radio capabilities. For example, the radio capabilities can support a RAT or system that UE 115 can use to communicate with the network (e.g., core network 130) via base station 105. Examples of such RATs and systems may include LTE systems, LTE-A systems, LTE-A Pro systems, machine-mounted LTE (LTE-M) systems, 4G systems, NR systems, 5G systems, Evolved Universal Terrestrial Radio Access Network (E-UTRAN), EPS, Global System for Mobile Communications Edge Radio Access Network (GERAN), E-UTRA connected to 5GC, Universal Mobile Telecommunications System (UMTS), and NB-IoT interfaces, as well as other RATs and systems.
[0089] In some cases, UE 115 may communicate with base station 105 based on a first radio capability (e.g., using a 5G system) and may autonomously reselect to communicate with base station 105 or another base station 105 based on a second radio capability (e.g., using an LTE system), as instructed by core network 130. However, in some cases, UE 115 may be restricted from communicating based on the second radio capability based on its subscription. For example, if UE 115's subscription indicates that UE 115 is a Closed Access Group (CAG) UE, then UE 115 may be restricted from using the LTE system or EPS. UE 115 may be unaware of this restriction and may attempt to reselect to the RAT or system corresponding to the second radio capability because the UE supports the radio capability for communication using the corresponding RAT or system. Core network 130 may subsequently reject UE 115 (e.g., based on the subscription of a UE that restricts the UE's use of the second radio capability) and, in some cases, may allocate a timer to UE 115 to prevent UE 115 from attempting to reselect to the corresponding RAT or system for a period of time. However, UE 115 can continue to attempt to reselect to the RAT or system corresponding to the limited radio capability after the timer expires. Additionally or alternatively, if UE 115 switches to another Public Land Mobile Network (PLMN) and then switches back, UE 115 can repeatedly attempt to select the RAT or system corresponding to the limited radio capability. Due to the increased signaling between the UE and the base station, attempting to reselect to the RAT or system corresponding to the limited radio capability may increase latency, channel overhead, and power loss, ultimately causing the reselection process for the RAT or system to fail.
[0090] Various aspects of the described technology support network-controlled disabling of radio capabilities supported by UE 115. For example, UE 115 may send a UE capability message to core network 130 via base station 105. The UE capability message may indicate the set of radio capabilities supported by UE 115 and, in some examples, may be sent to core network 130 as part of the registration process for registering UE 115. Core network 130 may receive the UE capability message and may identify subscription information associated with UE 115, which includes one or more radio capabilities restricted to UE 115. Core network 130 may use the subscription information to determine a radio capability modification indication indicating one or more restricted radio capabilities and to determine a UE radio capability identifier for UE 115. The UE radio capability identifier may correspond to a subset of unrestricted radio capabilities in the set of radio capabilities. Core network 130 may send a message indicating the UE radio capability identifier and the radio capability modification indication to UE 115 (e.g., a NAS message via base station 105). UE 115 can receive messages and communicate with base station 105 based on radio capabilities in a subset of radio capabilities (e.g., unrestricted radio capabilities). Based on the identification of restricted radio capabilities from the radio capability modification indication, UE 115 can avoid reselecting to the RAT or system corresponding to the restricted radio capability.
[0091] Figure 2 An example of a network-controlled disabled wireless communication system 200 supporting UE radio capabilities according to various aspects of this disclosure is illustrated. In some examples, wireless communication system 200 may implement various aspects of wireless communication system 100. For example, wireless communication system 200 may include base station 105-a and UE 115-a, which may be references Figure 1 Examples of base station 105 and UE 115 are described. In some examples, wireless communication system 200 may support one or more RATs, including 4G systems such as LTE systems, LTE-A systems, or LTE-A Pro systems, 5G systems that may be referred to as NR systems, or any combination of these or other RATs. In some cases, base station 105-a may implement UE radio capability identifier (ID) 210 and modification indication 215, and UE 115-a may implement registration message 205 to support network-controlled radio capability restrictions.
[0092] Base station 105-a and UE 115-a can communicate using uplink channel 220 and downlink channel 225. For example, UE 115-a can send uplink messages to base station 105-a via uplink channel 220 and receive downlink messages from base station 105-a via downlink channel 225. In some examples, UE 115-a and base station 105-a can communicate based on one or more radio capabilities. For example, UE 115-a can support communication with base station 105-a using various RATs or systems (e.g., 4G systems, 5G systems, or some other RATs or systems).
[0093] UE 115-a may initiate a registration process by sending a registration message 205 to base station 105-a via uplink channel 220. UE 115-a may initiate a registration process to register with a network (e.g., core network 130) connected to base station 105-a. UE 115-a may include UE capability messages (e.g., with registration message 205) indicating the set of radio capabilities supported by UE 115-a. In some examples, UE 115-a may send the UE capability messages as a different message than registration message 205. In some other examples, registration message 205 may include aspects of the UE capability messages.
[0094] Base station 105-a can receive registration message 205 and forward it to the network. The network can identify subscription information associated with UE 115-a in response to receiving the registration message. In some examples, subscription information can indicate one or more radio capabilities restricted to UE 115-a. For example, subscription information can indicate that UE 115-a is CAG-only (e.g., restricted LTE and EPS), restricted LTE, restricted EPS, restricted NR, restricted 5G, restricted GERAN, restricted UMTS, restricted NB-IoT, restricted carrier-specific, restricted E-UTRAN, or any combination thereof. For example, if UE 115-a is restricted NR, UE 115-a may not be allowed to communicate with base station 105-a using the NR system while operating under a specific subscription.
[0095] The network can remove one or more restricted radio capabilities from the set of radio capabilities based on identified subscription information. For example, the network can apply a filter to the set of radio capabilities corresponding to one or more restricted radio capabilities to obtain a subset of radio capabilities that does not include restricted radio capabilities. The network can determine the UE radio capability ID 210 corresponding to the subset of radio capabilities and can determine a modification indication 215 indicating one or more restricted radio capabilities. Alternatively, the modification indication 215 can indicate unrestricted radio capabilities (e.g., a subset of radio capabilities).
[0096] The network can forward the UE radio capability ID 210 and modification indication 215 to base station 105-a, and base station 105-a can send a message including the UE radio capability ID 210 and modification indication 215 to UE 115-a. In some examples, base station 105-a may include the UE radio capability ID 210 and modification indication 215 in a registration accept message, UE configuration update message, tracking area update (TAU) accept message, attach accept message, globally unique temporary identifier (GUTI) reallocation message, or any combination thereof. In some cases, modification indication 215 may be indicated in a bit field of the message.
[0097] UE 115-a can disable one or more restricted radio capabilities based on receiving modification indication 215. For example, UE 115-a can store a mapping from a set of modification indication values to multiple corresponding restricted radio capability sets. UE 115-a can determine the value of modification indication 215 and can map the modification indication value to the corresponding restricted radio capability set. UE 115-a can disable the radio capability corresponding to the restricted radio capability set. In some examples, UE 115-a can receive the mapping in a configuration message sent by base station 105-a. In some cases, the mapping can be operator-specific. In some examples, the mapping (e.g., operator-specific mapping) can support band-level granularity or other reduced-granularity restrictions on radio capabilities. For example, the mapping (e.g., operator-specific mapping) can support the network disabling one or more bands of a specific RAT, rather than completely disabling the RAT.
[0098] In some examples, UE 115-a can disable one or more restricted radio capabilities while using UE Radio Capability ID 210. For example, UE Radio Capability ID 210 may be associated with a specific serving PLMN. If UE 115-a is connected to a different PLMN, UE 115-a can initiate a registration process for that different PLMN. UE 115-a can enable previously disabled radio capabilities. UE 115-a can receive a new UE Radio Capability ID 210 and a new modification instruction 215, and can disable one or more restricted radio capabilities in the radio capability set based on the received new modification instruction 215.
[0099] In some examples, UE 115-a can receive UE radio capability ID 210 and modification indication 215 while operating in connected mode with the network. UE 115-a can continue to operate according to the full set of radio capabilities while in connected mode (e.g., despite receiving modification indication 215 indicating restricted radio capabilities) until it enters idle mode. When UE 115-a has no data to communicate with the network, UE 115-a can enter idle mode. UE 115-a can disable one or more restricted radio capabilities when entering idle mode or after entering idle mode, such that when UE 115-a re-enters connected mode, UE 115-a can operate according to a subset of radio capabilities (e.g., the restricted radio capabilities are disabled).
[0100] UE 115-a can avoid reselecting to a RAT or system corresponding to one or more restricted radio capabilities based on receiving modification instruction 215. For example, the modification instruction can indicate one or more radio capabilities restricted to UE 115-a. Therefore, UE 115-a can be aware of one or more restricted radio capabilities and can avoid reselecting to a RAT or system corresponding to one or more restricted radio capabilities (e.g., based on an autonomous reselection process at UE 115-a or a reselection command from the network).
[0101] Figure 3 An example of a network-controlled disabled wireless communication system 300 supporting UE radio capabilities according to various aspects of this disclosure is illustrated. In some examples, wireless communication system 300 may implement aspects of wireless communication systems 100 and 200. For example, wireless communication system 300 may include core network 305 and UE 115-b. Core network 305 may be a reference... Figure 1 The description includes an example of core network 130, and UE 115-b can be used as a reference. Figure 1 and Figure 2 Examples of UE 115 described. In some examples, wireless communication system 300 may support one or more RATs, including 4G systems such as LTE systems, LTE-A systems or LTE-A Pro systems, 5G systems that may be referred to as NR systems, or any combination of these or other RATs (e.g., higher generation RATs, lower generation RATs or both).
[0102] The core network 305 may include multiple network entities (e.g., functions) to facilitate communication with UE 115-b. For example, the core network 305 may include AMF 310, UE Radio Capability Management Function (UCMF) 315, and Unified Data Management (UDM) 320, as well as other network devices or network entities (not shown) to facilitate communication with UE 115-b. In some cases, AMF 310, UCMF 315, and UDM 320 may communicate via one or more links 325. For example, AMF 310 may communicate with UDM 320 using link 325-a and with UCMF using link 325-b. In some examples, AMF 310, UCMF 315, UDM 320, or any combination thereof, may be implemented in hardware, software, firmware, or some combination thereof.
[0103] AMF 310 can provide access and mobility management services to UE 115-b and base station 105 (not shown), through which UE 115-b communicates with core network 305. In some examples, AMF 310 can act as the master point for control plane signaling communication with UE 115-b, allowing most control plane communication between UE 115-b and core network 305 to pass through AMF 310. Additionally or alternatively, AMF 310 can facilitate authentication and / or authorization of UE 115-b, enabling UE 115-b to communicate with core network 305 using NAS protocols configured to securely establish and maintain connectivity between UE 115-b and core network 305. In some cases, core network 305 may include MME or some other mobility management function as a supplement to or replacement of AMF 310.
[0104] The UCMF 315 can store radio capability ID mappings in a network (e.g., a PLMN) serving UE 115-b. In some cases, the PLMN may be a network comprising one or more RATs or systems supported by a specific operator (e.g., within a specific country) and can provide services to UE 115-b (e.g., voice calls, messaging services, data services, or other services). The UCMF 315 can be responsible for allocating radio capability IDs within the PLMN. Furthermore, the UCMF 315 can store radio capability IDs and the radio capability information to which these radio capability IDs are mapped. In some examples, the radio capability IDs stored in the UCMF can be associated with one or more radio capability formats. The radio capability format can be identified by both the UCMF 315 and the AMF 310, and in some examples, the UCMF 315 can be configured to transcode between radio capability formats. For example, if the radio capability format is encoded in Abstract Syntax Notation 1 (ASN.1), the UCMF 315 can be configured to read ASN.1 and transcode the radio capability into another format (e.g., a format supported by the core network 305).
[0105] UDM 320 can support user identification processing and subscription retrieval, among other operations. For example, UDM 320 can store and manage a permanent subscription identifier for each subscriber in a system (e.g., a 5G system). Furthermore, UDM 320 can support the retrieval of subscription information for UE 115. In some examples, UDM 320 can store the Serving AMF 310 and Serving Session Management Function (SMF) for Packet Data Unit sessions. In some cases, core network 305 may include Home Subscriber Service (HSS) or another user data management function or system as a supplement to or replacement of UDM 320.
[0106] UE 115-b can register with the core network 305 by performing a registration process. For example, UE 115-b and the core network 305 can communicate via communication link 125-a (e.g., via base station 105 (not shown)), which can be a reference link. Figure 1 An example of communication link 125 is described. UE 115-b can initiate a registration process by sending a registration message (e.g., an attach request message or some other registration message) to core network 305 via communication link 125-a. The registration message may include a radio capability message indicating the set of radio capabilities supported by UE 115-b. In some cases, UE 115-b may send the radio capability message and the registration message as separate messages.
[0107] Core network 305 can receive radio capability messages and forward them to AMF 310. For example, base station 105 connected to core network 305 can receive radio capability messages and forward them to AMF 310. In response to receiving a radio capability message, AMF 310 can retrieve subscription information for UE 115-b from UDM 320. In some examples, UDM 320 can send subscription information to AMF 310 in response to core network 305 receiving a radio capability message. Subscription information may include one or more radio capabilities restricted to UE 115-b. For example, subscription information may indicate that UE 115-b is CAG only (e.g., restricted LTE and EPS), restricted LTE, restricted EPS, restricted NR, restricted 5G, restricted GERAN, restricted UMTS, restricted NB-IoT, restricted carrier-specific, restricted E-UTRAN, or any combination thereof. In some examples, the restrictions may limit the RAT's use of one or more resources (e.g., frequency bands) rather than completely restricting the RAT.
[0108] AMF 310 can determine mobility restriction information from subscription information. For example, AMF 310 can determine mobility restriction information indicating one or more restricted radio capabilities indicated in the subscription information. AMF 310 can determine the set of radio capabilities supported by UE 115-b as indicated in the radio capability message and can send (e.g., input) the radio capability set and mobility restriction information to UCMF 315. In some examples, AMF 310 can send the radio capability set and mobility restriction information to UCMF 315 as part of a service operation (e.g., the Nucmf_UECapabilityManagement_Assign service operation). In some cases, AMF 310 can include the radio capability set, one or more encoding formats associated with the radio capability set, a type assignment code, mobility restriction information, or any combination thereof in a message sent to UCMF 315 as part of a service operation. In some examples, mobility information can be an enumeration value (e.g., a bit field) indicating one or more restricted radio capabilities.
[0109] UCMF 315 can determine a subset of radio capabilities from a set of radio capabilities. For example, UCMF 315 can receive a set of radio capabilities and mobility restriction information as part of service operations. Based on the mobility restriction information (e.g., enumerated values), UCMF 315 can select filters to apply to the set of radio capabilities. In some examples, UCMF 315 can select filters from a defined set of filters. UCMF 315 can select filters such that by applying the filters, one or more restricted radio capabilities can be removed from the set of radio capabilities. UCMF 315 can apply filters to remove one or more restricted radio capabilities and obtain a subset of radio capabilities from the set of radio capabilities that includes unrestricted radio capabilities. For example, if UE 115-b is a CAG-only device, UCMF 315 can apply filters to remove LTE and EPS radio capabilities from the set of radio capabilities. In some examples, filters can be selected and applied to remove any combination of restricted radio capabilities from any set of radio capabilities.
[0110] UCMF 315 can determine the UE radio capability ID corresponding to a subset of radio capabilities based on an application filter. Furthermore, UCMF 315 can determine a radio capability modification indication, which indicates one or more restricted radio capabilities (e.g., explicit or implicit). In some examples, UCMF 315 can store (e.g., in a lookup table or in another format) a mapping from multiple sets of restricted radio capabilities to corresponding sets of radio capability modification indication values. UCMF 315 can determine the radio capability modification indication based on mobility restriction information received from AMF 310 and the mapping. For example, mobility restriction information may indicate a set of restricted radio capabilities, and UCMF 315 can use the mapping to determine the corresponding radio capability modification indication based on the set of restricted radio capabilities. In some cases, the mapping may be operator-specific. UE 115-b may store a similar mapping in memory (e.g., to resolve received radio capability modification indications to sets of restricted radio capabilities).
[0111] The UCMF 315 can output the UE radio capability ID and radio capability modification indication to the AMF 310. In some examples, the UCMF 315 can output the UE radio capability ID and radio capability modification indication to the AMF 310 in a single message, and the radio capability modification indication, the UE radio capability ID, or both can be included as bit fields of the message. If the radio capability modification indication is included in a bit field, that bit field can correspond to an enumerated value indicating one or more restricted radio capabilities. In some cases, the UCMF 315 can output the UE radio capability ID and radio capability modification indication to the AMF 310 as part of a service operation (e.g., the Nucmf_UECapabilityManagement_Assign service operation).
[0112] AMF 310 can receive the UE radio capability ID and radio capability modification indication, and assign the UE radio capability ID to UE 115-b. Core network 305 can send the UE radio capability ID and radio capability modification indication to UE 115-b (e.g., via base station 105). In some examples, core network 305 can send the UE radio capability ID and radio capability modification indication as part of a registration accept message, UE configuration update message, TAU accept message, attach accept message, GUTI reallocation message, or any combination thereof. UE 115-b can receive the UE radio capability ID and radio capability modification indication, and communicate with core network 305 based on one or more radio capabilities (e.g., unrestricted radio capabilities) of a subset of radio capabilities. In some examples, core network 305 can send a configuration message that includes a mapping from a set of restricted radio capabilities to radio capability modification indications stored in UCMF 315. In some other examples, UE 115-b may be pre-configured with the mapping. UE 115-b can use such a mapping and radio capability modification indication to determine one or more restricted radio capabilities.
[0113] Core network 305 can avoid redirecting UE 115-b to a RAT or system corresponding to restricted radio capabilities based on the determined radio capability modification indication. For example, core network 305 can store (e.g., at AMF 310) the UE radio capability ID or the radio capability modification indication, or both. Therefore, AMF 310 can identify UE 115-b radio capability limitations without retrieving subscription information from UDM 320, and can avoid redirecting UE 115-b to a restricted RAT or system based on the stored UE radio capability ID or the radio capability modification indication, or both.
[0114] In some examples, core network 305 can determine a subscription update for UE 115-b and can update the UE radio capability ID and radio capability modification indication based on the subscription update. For example, UDM 320 can determine a subscription update indicating changes to restricted radio capabilities associated with UE 115-b. UDM 320 can send the subscription update to AMF 310. AMF 310 can determine the set of radio capabilities indicated by the radio capability message and can determine updated mobility restriction information corresponding to the updated subscription information. AMF 310 can send (e.g., input) the set of radio capabilities and the updated mobility restriction information to UCMF 315. UCMF 315 can select and apply filters to the set of radio capabilities based on the updated mobility restriction information to obtain an updated subset of radio capabilities. UCMF 315 can determine the updated UE radio capability ID corresponding to the updated subset of radio capabilities and can determine the updated radio capability modification indication, which indicates one or more restricted radio capabilities associated with the updated subscription information. UCMF 315 can output the updated UE radio capability ID and the updated radio capability modification indication to AMF 310, and AMF 310 can assign the updated UE radio capability ID to UE 115-b. Core network 305 can send the updated UE radio capability ID and the updated radio capability modification indication to UE 115-b, and UE 115-b can communicate with core network 305 based on one or more radio capabilities of the updated radio capability subset.
[0115] The process described herein can be performed by: AMF 310, MME, or any other mobility management function; UDM320, HSS, or any other user data management function; UCMF 315; base station 105; or any combination of these or other network devices or entities. As described herein, network devices or entities may include: AMF 310, MME, or any other mobility management function; UDM 320, HSS, or any other user data management function; UCMF 315; base station 105; or any combination of these. Network devices or entities may perform one or more functions that support network control disablement of the UE radio capabilities as described herein.
[0116] Figure 4 An example of a process flow 400 supporting network control disabling of UE radio capabilities according to various aspects of this disclosure is illustrated. In some examples, process flow 400 may be implemented as described in the references. Figures 1 to 3The described wireless communication systems 100, 200, and 300 are described in various aspects. Process flow 400 can be implemented by AMF 310-a, UCMF 315-a, UDM 320-a, and UE 115-c to support radio capability limitations, preventing UE 115-c from reselecting to a RAT or system corresponding to the limited radio capability. Process flow 400 can also be implemented by AMF 310-a, UCMF 315-a, UDM 320-a, and UE 115-c to potentially reduce latency and power consumption at UE 115-c (e.g., based on mitigating communication associated with signaling attempts to reselect to a RAT or system corresponding to the limited radio capability), and to achieve other benefits.
[0117] AMF 310-a, UCMF 315-a, and UDM 320-a can be as referenced. Figure 3 Examples of AMF 310, UCMF315, and UDM 320 are described. UE 115-c can be as referenced. Figures 1 to 3 An example of UE 115 is described below. In the following description of process flow 400, operations between AMF 310-a, UCMF 315-a, UDM 320-a, and UE 115-c may communicate in a different order than the example shown, or operations performed by AMF 310-a, UCMF 315-a, UDM 320-a, and UE 115-c may be performed in a different order or at different times. Certain operations may also be omitted from process flow 400, and other operations may be added to process flow 400. In some examples, operations performed by AMF 310-a, UCMF 315-a, and UDM 320-a may be performed by additional or alternative network devices or network entities.
[0118] At point 405, UE 115-c can initiate a registration process with AMF 310-a to establish a connection with the core network. For example, UE 115-c can send a registration message (e.g., an attach request) to AMF 310-a (e.g., via base station 105). The registration message can indicate the set of radio capabilities supported by UE 115-c. In some cases, AMF 310-a can be an MME or some other mobility management function.
[0119] At 410, UDM 320-a can send subscription information of UE 115-c to AMF 310-a. For example, in response to receiving a registration message, AMF 310-a can retrieve the subscription information of UE 115-c from UDM 320-a. The subscription information may include one or more radio capabilities limited to UE 115-c. In some cases, UDM 320-a may be HSS or some other user data management function.
[0120] At 415, AMF 310-a can determine the set of radio capabilities supported by UE 115-c based on the received registration message. AMF 310-a can then send the set of radio capabilities to UCMF 315-a as part of the service operation.
[0121] At 420, AMF 310-a can determine mobility information from the subscription information received at 410. For example, AMF 310 can determine mobility information indicating one or more restricted radio capabilities indicated in the subscription information. AMF 310-a can send the mobility information to UCMF 315-a as part of a service operation. In some examples, 420 and 415 can occur simultaneously. For example, AMF 310-a can send the determined set of radio capabilities and mobility information to UCMF 315-a simultaneously or as part of the same message.
[0122] At 425, UCMF 315-a can apply filters to a set of radio capabilities based on mobility information. For example, UCMF 315-a can apply filters to a set of radio capabilities to remove one or more restricted radio capabilities indicated in the mobility information and obtain a subset of unrestricted radio capabilities. In some cases, UCMF 315-a can select filters from a defined filter set based on mobility information.
[0123] At 430, UCMF 315-a can determine a modification indication indicating one or more restricted radio capabilities. UCMF 315-a can send (e.g., output) the modification indication to AMF 310-a. In some examples, UCMF 315-a can determine the UE radio capability ID corresponding to a filtered subset of unrestricted radio capabilities and can send the UE radio capability ID to AMF 310-a at 430. In some cases, UCMF 315-a can send the UE radio capability ID and the modification indication to AMF 310-a simultaneously or as part of the same message.
[0124] At 435, the AMF 310-a can assign the UE radio capability ID to the UE 115-c. In some cases, the AMF310-a can store the UE radio capability ID or a modification indication, or both.
[0125] At 440, AMF 310-a may send (e.g., via base station 105) the UE radio capability ID to UE 115-c. At 445, AMF 310-a may send (e.g., via base station 105) a modification indication to UE 115-c. In some examples, 445 may occur simultaneously with 440. For example, AMF 310-a may send the UE radio capability ID as part of a registration accept message, UE configuration update message, TAU accept message, attach accept message, GUTI reallocation message, or any combination thereof, and may include a modification indication in the bit fields of the message. UE 115-c may receive the message and may communicate with the network including AMF 310-a, UCMF 315-a, and UDM320-a based on one or more radio capabilities of a filtered subset of unrestricted radio capabilities. For example, UE 115-c may disable the restricted radio capability indicated by the modification indication and may avoid autonomously reselecting to the RAT or system corresponding to the restricted radio capability.

For example, the communication manager 520, receiver 510, transmitter 515, or various combinations thereof, or components thereof, may support methods for performing one or more functions described herein.
[0130] In some examples, the communication manager 520, receiver 510, transmitter 515, or various combinations or components thereof may be implemented in hardware (e.g., in communication management circuitry). The hardware may include a processor, digital signal processor (DSP), application-specific integrated circuit (ASIC), field-programmable gate array (FPGA) or other programmable logic device, discrete gate or transistor logic, discrete hardware components, or any combination thereof configured to or otherwise support components for performing the functions described herein. In some examples, the processor and memory coupled to the processor may be configured to perform one or more functions described herein (e.g., by executing instructions stored in memory by the processor).
[0131] Additionally or alternatively, in some examples, the communication manager 520, receiver 510, transmitter 515, or various combinations or components thereof may be implemented in code executed by a processor (e.g., as communication management software or firmware). If implemented in processor-executed code, the functionality of the communication manager 520, receiver 510, transmitter 515, or various combinations or components thereof may be performed by any combination of a general-purpose processor, DSP, central processing unit (CPU), ASIC, FPGA, or these or other programmable logic devices (e.g., components configured or otherwise supported for performing the functions described in this disclosure).

[0133] Communication manager 520 may support wireless communication at the UE according to the examples disclosed herein. For example, communication manager 520 may be configured or otherwise supported to support components for transmitting UE capability messages indicating a set of UE radio capabilities to the network via a base station. Communication manager 520 may be configured or otherwise supported to support components for receiving messages indicating a UE radio capability identifier and a radio capability modification indication from the network via a base station, wherein the UE radio capability identifier corresponds to a subset of the UE radio capability set based on a radio capability modification indication indicating one or more UE radio capabilities to be restricted from the UE radio capability set. Communication manager 520 may be configured or otherwise supported to support components for communicating with the network based on a subset of the UE radio capability set corresponding to the UE radio capability identifier.
[0134] By including or configuring a communication manager 520 according to the examples described herein, device 505 (e.g., a processor that controls or otherwise couples to receiver 510, transmitter 515, communication manager 520, or any combination thereof) can reduce processing resources and power consumption associated with mobility management procedures. For example, by limiting radio capabilities at the UE, device 505 can eliminate or mitigate signaling communications associated with the UE attempting to reselect to a RAT or system corresponding to the limited radio capabilities.
[0135] Figure 6 A block diagram 600 illustrates a device 605 supporting network control disabling of UE radio capabilities according to various aspects of this disclosure. Device 605 may be an example of a device 505 as described herein or a aspect of UE 115. Device 605 may include a receiver 610, a transmitter 615, and a communications manager 620. Device 605 may also include a processor (not shown). Each of these components may communicate with each other (e.g., via one or more buses).
[0136] Receiver 610 may provide components for receiving information such as packets associated with various information channels (e.g., control channels, data channels, information channels related to network control disabling of UE radio capabilities), user data, control information, or any combination thereof. The information may be transmitted to other components of device 605. Receiver 610 may utilize a single antenna or a collection of antennas.
[0137] Transmitter 615 may provide components for transmitting signals generated by other components of device 605. For example, transmitter 615 may transmit information such as packets, user data, control information, or any combination thereof associated with various information channels (e.g., control channels, data channels, and information channels related to network control disabling of UE radio capabilities). In some examples, transmitter 615 may be co-located with receiver 610 in a transceiver module. Transmitter 615 may utilize a single antenna or a collection of multiple antennas.

[0150] Figure 8 A diagram of a system 800 including a network control disable device 805 supporting UE radio capabilities, according to various aspects of this disclosure, is shown. Device 805 may be an example of device 505, device 605, or UE 115 as described herein, or may include components thereof. Device 805 may wirelessly communicate with one or more base stations 105, UE 115, or any combination thereof. Device 805 may include components for bidirectional voice and data communication, including components for transmitting and receiving communications, such as a communication manager 820, an input / output (I / O) controller 810, a transceiver 815, an antenna 825, a memory 830, code 835, and a processor 840. These components may communicate electronically or be otherwise coupled (e.g., operative ground, communication ground, functional ground, electronic ground, electrical ground) via one or more buses (e.g., bus 845).
[0151] I / O controller 810 can manage the input and output signals of device 805. I / O controller 810 can also manage peripheral devices not integrated into device 805. In some cases, I / O controller 810 can represent a physical connection or port to an external peripheral device. In some cases, I / O controller 810 can utilize, for example... , MS- MS- OS / , Or another known operating system. Additionally or alternatively, the I / O controller 810 may represent or interact with a modem, keyboard, mouse, touchscreen, or similar device. In some cases, the I / O controller 810 may be implemented as part of a processor, such as processor 840. In some cases, a user may interact with device 805 via the I / O controller 810 or via hardware components controlled by the I / O controller 810.
[0152] In some cases, device 805 may include a single antenna 825. However, in other cases, device 805 may have more than one antenna 825, which may be able to transmit or receive multiple wireless transmissions simultaneously. Transceiver 815 may communicate bidirectionally via one or more antennas 825, wired or wireless links as described herein. For example, transceiver 815 may represent a wireless transceiver and may communicate bidirectionally with another wireless transceiver. Transceiver 815 may also include a modem for modulating packets and providing modulated packets to one or more antennas 825 for transmission, and for demodulating packets received from one or more antennas 825. Transceiver 815, or transceiver 815 and one or more antennas 825, may be an example of transmitter 515, transmitter 615, receiver 510, receiver 610, or any combination thereof or components thereof as described herein.
[0153] Memory 830 may include random access memory (RAM) and read-only memory (ROM). Memory 830 may store computer-readable, computer-executable code 835, including instructions that, when executed by processor 840, cause device 805 to perform the various functions described herein. Code 835 may be stored in a non-transitory computer-readable medium such as system memory or other types of memory. In some cases, code 835 may not be directly executable by processor 840, but may enable a computer (e.g., when compiled and executed) to perform the functions described herein. In some cases, memory 830 may, in particular, include a basic I / O system (BIOS) that controls basic hardware or software operations, such as interaction with peripheral components or devices.
