Techniques for enhancing user equipment performance for multi-subscriber identity module operation

Abstract

Methods, systems, and devices are described for wireless communication at a user equipment (UE). The UE can identify a first set of frequency bands associated with a first subscription and a second set of frequency bands associated with a second subscription. The UE can determine that at least a first frequency band from the first set of frequency bands and at least a second frequency band from the second set of frequency bands share a same set of radio frequency (RF) front-end resources. The UE can then refrain from communicating on a third frequency band from the first set of frequency bands while communicating on the remaining set of frequency bands, where the third frequency band can be associated with a secondary component carrier (SCC) of a multi-carrier communication scheme. The refraining from communicating on the third frequency band can be based on the first frequency band and the second frequency band sharing the RF front-end resources and the third frequency band being associated with the SCC.

[0003] open field

[0004] The scope of this disclosure relates, for example, to wireless communication at a user equipment (UE), including techniques for enhancing the performance of a UE for operation of a multi-subscriber identification module. Background Technology

[0005] Wireless communication systems are widely deployed to provide various types of communication content, such as voice, video, packet data, message sending and receiving, broadcasting, and so on. 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) systems, LTE-A Advanced (LTE-A) systems, or LTE-A Pro systems) and fifth-generation (5G) systems, which may be referred to as New Radio (NR) systems. These systems can employ various 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).

[0006] The UE can support multiple subscriptions to connect to multiple networks simultaneously. Additionally, the UE can support a non-autonomous architecture to connect to multiple networks. In some situations, communication in a non-autonomous architecture may be unstable and could adversely affect the UE's performance.

[0007] Overview

[0008] The described technology relates to improved methods, systems, devices, and apparatuses for supporting technologies that enhance the performance of user equipment (UE) for multi-subscriber identification module (MSI) operation. In some examples, the described technology allows the UE to communicate using enhanced technologies. The UE may be configured with multiple MSI modules. Each MSI module may be associated with a subscription that allows the UE to connect to and communicate with a network. In some cases, each MSI module may be connected to a different network, associated with a different radio access technology, or any combination thereof. In some examples, the UE may be connected to a first cell in a non-autonomous operating mode. Additionally, a first frequency band on a first subscription and a second frequency band on a second subscription may have the same downlink path, resulting in complete disengagement at the UE, for example, where the UE may disengage from the first subscription to another subscription (e.g., for idle mode operation), where the first subscription may lose access to radio frequency resources during the disengagement period.

[0009] According to some aspects, the UE may identify a first set of frequency bands associated with a first subscription and a second set of frequency bands associated with a second subscription. In some examples, the second subscription may be different from the first subscription. The UE may determine that at least one frequency band from the first set of frequency bands and at least one frequency band from the second set of frequency bands share a set of radio frequency (RF) front-end resources. For example, the UE may determine that a certain combination of frequency bands associated with each subscription may cause the UE to perform a complete disengagement operation from a subscription when communicating using that combination of frequency bands. The UE may then suppress communication on a frequency band from the first set of frequency bands. As an example, the UE may suppress communication on a frequency band from the first set of frequency bands, where the frequency band may be associated with a sub-component carrier, based on determining that the first frequency band from the first set of frequency bands and the second frequency band from the second set of frequency bands share a set of RF front-end resources. By suppressing communication on a frequency band associated with a sub-component carrier, the first and second frequency bands can be fully concurrent, thereby avoiding disengagement.

[0041] Detailed description

[0042] User equipment (UE) can use a dual (e.g., non-autonomous) architecture to support communication with the network, where different radio access technologies can be used concurrently or simultaneously. For example, a non-autonomous UE can be anchored to or connected to a cell associated with a first radio access technology (e.g., LTE) while facilitating communication with cells associated with a second radio access technology (e.g., NR). In some cases, the cells associated with each radio access technology can be associated with a single base station (e.g., provided by a single base station, associated with a single base station) or can be associated with separate base stations.

[0043] As described herein, some wireless networks can be configured to operate in a dual connectivity configuration. For example, a wireless network can be configured to operate in an Evolved Universal Terrestrial Radio Access Network (E-UTRAN) in NR (which may be referred to as EN-DC, 5GEN-DC, or a 5G NR dual connectivity configuration or system, or a combination thereof). Broadly speaking, a dual connectivity configuration can support a UE simultaneously connecting to two cells or two devices, such as base stations (or nodes). In some examples, one node (e.g., the primary node) can be a 5G (e.g., NR) node, and the second node (e.g., the secondary node) can be an LTE node. In other examples, the primary node can be an LTE node, and the secondary node can be a 5G (e.g., NR) node. In some examples, both the primary and secondary nodes can be 5G (e.g., NR) nodes, or they can both be LTE nodes. Dual connectivity configurations are supported when interconnectivity between the primary and secondary nodes has been established via one or more backhaul links, core network functions, etc. Examples of dual connectivity may include a UE connecting to LTE and 5G NR nodes concurrently or simultaneously, or a UE using an LTE node for control plane information and a 5G NR node for user plane traffic, or any combination thereof. In some aspects, dual connectivity configurations may support direct or split signaling radio bearers (or both).

[0044] In some wireless communication systems, a UE can be configured with multiple subscriber identity modules. That is, the UE can support a first subscriber identity module (SIM) corresponding to a first subscription, and the UE can further support a second SIM corresponding to a different second subscription. This type of technology may be referred to as multiple subscriber identity modules (MSIM), multiple SIM, or other similar terms. Each subscriber identity module can be associated with a subscription that allows the UE to connect to and communicate with a network. In some cases, each subscriber identity module can connect to different networks. For example, the UE may have a first subscriber identity module using a first subscription that provides access to a first network (e.g., a 5G network), and a second subscriber identity module using a second subscription that provides access to a second network (e.g., a 4G network). Alternatively, the first subscriber identity module using the first subscription and the second subscriber identity module using the second subscription can provide access to the same network. In some examples, the first subscriber identity module using the first subscription and the second subscriber identity module using the second subscription can be configured to support NR technology and can be configured to operate concurrently or simultaneously in a non-autonomous operation mode.

[0045] According to one or more aspects of this disclosure, a UE can use a first subscription and a second subscription to establish a connection with a cellular cell of a radio access technology. When operating in a non-autonomous operating mode, the UE can be configured with a first set of frequency bands for the first subscription and a second set of frequency bands for the second subscription. In some instances, the UE hardware can be designed such that the first frequency band on the first subscription and the second frequency band on the second subscription have the same downlink path. That is, the first frequency band on the first subscription and the second frequency band on the second subscription can be configured to share a common set of radio frequency (RF) front-end resources. For example, the UE can be configured with a set of RF frequency bands (e.g., band B66, band B2, and band n71) on the first subscription and another set of RF frequency bands (e.g., wideband code division multiple access (WCDMA) band B2) on the second subscription. In this example, the n71 band and the WCDMA B2 band can be configured to use a shared set of resources (e.g., the UE's RF front-end resources), resulting in the complete offloading of the n71 band, for example, during paging operations on the WCDMA B2 band (e.g., in idle mode). Because the n71 band can provide high throughput (e.g., according to NR technology) and can be used for network communication, this complete offloading hinders the overall throughput supported by the UE, and consequently impairs UE performance and degrades the user experience.

[0046] To reduce latency and improve resource efficiency, the UE may determine that a band combination is not fully concurrent and that the UE may be configured to perform a full disengagement operation when communicating using that band combination. In such cases, the UE may subsequently suppress communication on some bands (e.g., discard some bands, reduce the priority of some bands) to enable communication on the determined band combination without full disengagement. In some examples, if a band associated with a sub-component carrier is configured at the first subscription, the UE may discard the band associated with that sub-component carrier. In another example, the UE may reduce the priority of a band combination, causing the UE to switch to full disengagement mode when such a band is active. In some aspects, the UE determines a band combination that causes it to switch to full disengagement mode. In such examples, the UE may suppress the inclusion of indications for such band combinations in the capability report given to the base station.

[0047] A UE capable of supporting full concurrency across multiple subscriptions can leverage the techniques described herein to experience power savings, such as reduced power consumption and extended battery life, while ensuring reliable and efficient communication between the UE and the base station, and other benefits. Various aspects of the subject matter described in this disclosure can be implemented to achieve one or more of the following potential advantages. The techniques employed by the described UE can provide benefits and enhancements to the operation of the UE. For example, the operations performed by the UE can provide improvements to radio operation. Additionally or alternatively, the techniques employed by the described UE can provide time and power savings for multiple subscriptions. In some examples, according to various aspects of this disclosure, the UE can support high reliability and low latency communication, etc. The described techniques can thus include features for improving power consumption, spectral efficiency, higher data rates, and in some examples, enhanced efficiency for high reliability and low latency operation, as well as other benefits.

[0048] The aspects of this disclosure are initially described in the context of wireless communication systems. The aspects of this disclosure are further described in the context of hardware configuration and process flow. The aspects of this disclosure are further explained and described by means of, and with reference to, apparatus diagrams, system diagrams, and flowcharts relating to techniques for enhancing the performance of user equipment used in the operation of multi-subscriber identification modules.

[0049] Figure 1 Examples of wireless communication systems 100 supporting technologies for enhancing the performance of user equipment (UEs) for multi-subscriber identification module (MSI) operation, according to various aspects of this disclosure, are described. 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, wireless communication system 100 may be an LTE network, an Advanced LTE (LTE-A) network, an LTE-A Pro network, or an NR network. In some examples, 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.

[0050] Base station 105 can be distributed across a geographical area to form wireless communication system 100, and can be different types of devices or devices with different capabilities. Base station 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 on the coverage area 110. 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 radio access technologies.

[0051] Each UE 115 can be distributed throughout the coverage area 110 of the wireless communication system 100, and each UE 115 can be stationary or mobile, or stationary and mobile at different times. Each UE 115 can be a different type of device or a device with different capabilities. Figure 1 The document describes some example UE 115s. The UE 115 described herein can communicate with various types of devices, such as other UE 115s, base station 105, or network equipment (e.g., core network nodes, relay equipment, integrated access and backhaul (IAB) nodes, or other network equipment). Figure 1 As shown in the image.

[0052] Each base station 105 may communicate with the core network 130, or with each other, or both. For example, base station 105 may interface with the core network 130 via one or more backhaul links 120 (e.g., via S1, N2, N3, or other interfaces). Base stations 105 may communicate with each other directly (e.g., directly between base stations 105), indirectly (e.g., via the core network 130), or directly and indirectly on backhaul links 120 (e.g., via X2, Xn, or other interfaces). In some examples, backhaul link 120 may be or include one or more radio links.

[0053] 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 transceiver station, radio base station, access point, radio transceiver, B node, evolved B node (eNB), next-generation B node or gigabit B node (any of which may be referred to as gNB), home B node, home evolved B node, or other suitable terms.

[0054] UE 115 may include or be referred to as a mobile device, wireless device, remote device, handheld device, or subscriber device, or any other suitable term, wherein "device" may also be referred to as a unit, station, terminal, or client, etc. 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, which can be implemented in various objects such as appliances or vehicles, meters, etc.

[0055] The UE 115 described herein can communicate with various types of devices, such as other UEs 115 that sometimes act as relays, as well as base station 105 and network equipment including macro eNBs or gNBs, small cell eNBs or gNBs, or relay base stations, etc. Figure 1 As shown in the image.

[0056] 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 frequency 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 of the radio spectrum band (e.g., a bandwidth portion (BWP)) operating according to one or more physical layer channels for a given radio access technology (e.g., LTE, LTE-A, LTE-A Pro, NR). Each physical layer channel may carry acquisition signaling (e.g., synchronization signals, system information), control signaling coordinating carrier operation, user data, or other signaling. Wireless communication system 100 may support communication with UE 115 using carrier aggregation or multi-carrier operation. UE 115 may be configured to have multiple downlink component carriers and one or more uplink component carriers according to a carrier aggregation configuration. Carrier aggregation may be used in conjunction with both frequency division duplex (FDD) and time division duplex (TDD) component carriers.

[0057] In some examples (e.g., in a carrier aggregation configuration), the carrier may also have acquisition signaling or control signaling to coordinate the operation of other carriers. The 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 may be located according to a channel grid for discovery by UE 115. The carrier may operate in an autonomous mode in which initial acquisition and connection can be performed by UE 115 via that carrier, or in a non-autonomous mode in which the carrier may connect to carriers anchored using different carriers (e.g., different carriers of the same or different radio access technologies).

[0058] 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).

[0059] A carrier may be associated with a bandwidth of the radio frequency spectrum, and in some examples, this carrier bandwidth may be referred to as the carrier or the "system bandwidth" of the wireless communication system 100. For example, the carrier bandwidth may be one of several defined bandwidths of a carrier of a radio access technology (e.g., 1.4, 3, 5, 10, 15, 20, 40, or 80 MHz). Devices of the wireless communication system 100 (e.g., base station 105, UE 115, or both) may have hardware configurations that support communication over the carrier bandwidth, or may be configurable to support communication over a single carrier bandwidth within a set of carrier bandwidths. In some examples, the wireless communication system 100 may include a base station 105 or UE 115 that supports simultaneous communication via carriers associated with multiple carrier bandwidths. In some examples, each served UE 115 may be configured to operate over a portion (e.g., a subband, BWP) or all of the carrier bandwidth.

[0060] The signal waveform transmitted on the carrier may include 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 may 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 may depend on the modulation scheme (e.g., the order of the modulation scheme, the code rate of the modulation scheme, or both). Thus, 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 achieve. Wireless communication resources can refer to a combination of radio frequency spectrum resources, temporal resources, and spatial resources (e.g., spatial layers or beams), and using multiple spatial layers can further improve the data rate or data integrity of communication with the UE 115.

[0061] It can support one or more sets of parameters for the carrier, wherein the parameter sets may include the subcarrier spacing ( Δf (and cyclic prefix). A carrier can be divided into one or more BWPs with the same or different parameter designs. In some examples, UE 115 can be configured with multiple BWPs. In some examples, a single BWP for a carrier can be active at a given time, and communication for UE 115 can be limited to one or more active BWPs.

[0062] The time interval of base station 105 or UE 115 can be expressed as a multiple of a basic time unit, such as the sampling period. T s =1 / ( Δf max Nf ) seconds, of which Δf max This can represent the maximum supported subcarrier spacing, while N f This can represent the maximum supported Discrete Fourier Transform (DFT) size. The time interval of the 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 a System Frame Number (SFN) (e.g., ranging from 0 to 1023).

[0063] 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 (e.g., in the time domain) be divided into subframes, and each subframe may be further divided into several 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 several symbol periods (e.g., depending on the length of the cyclic prefix added before each symbol period). In some wireless communication systems 100, time slots may be further divided into multiple mini-time slots containing one or more symbols. Excluding 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.

[0064] A subframe, time slot, mini-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 bursts of shortened TTIs (sTTIs)).

[0065] Physical channels can be multiplexed on a carrier using various techniques. Physical control channels and physical data channels can be multiplexed on a downlink carrier, for example, using one or more of time-division multiplexing (TDM), frequency-division multiplexing (FDM), or hybrid TDM-FDM techniques. 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 across the system bandwidth or a subset of the system bandwidth of the carrier. One or more control regions (e.g., CORESET) can be configured for a set of UEs 115. For example, one or more of the UEs 115 can monitor or search 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 in one or more aggregation levels arranged in a cascaded manner. An 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 in a control information format having a given payload size. The search space set may include a common search space set configured to send control information to multiple UEs 115 and a UE-specific search space set configured to send control information to a specific UE 115.

[0066] Each base station 105 may provide communication coverage via one or more cells (e.g., macrocells, 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., on a carrier) and may be associated with an identifier used to distinguish adjacent cells (e.g., Physical Cell Identifier (PCID), Virtual Cell Identifier (VCID), or others). 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. The extent of such cells may vary from smaller areas (e.g., structures, subsets of structures) to larger areas depending on various factors such as the capabilities of base station 105. For example, a cell may be or include buildings, subsets of buildings, or external space between or overlapping geographic coverage areas 110, among other examples.

[0067] Macrocells cover a relatively large geographic area (e.g., a radius of several kilometers) and allow unrestricted access for UEs 115 that have service subscriptions with a network provider supporting the macrocell. Small cells may be associated with a lower-power base station 105 (compared to macrocells) and may operate in the same or different (e.g., licensed or unlicensed) frequency bands as macrocells. Small cells may provide unrestricted access to UEs 115 that have service subscriptions with a network provider, or may provide restricted access to UEs 115 associated with a small cell (e.g., UE 115 in a Closed Subscriber Group (CSG), or UE 115 associated with a user in a home or office). Base station 105 may support one or more cells and may also support communication on one or more cells using one or more component carriers.

[0068] 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)).

[0069] In some examples, base station 105 may be mobile, and thus provide communication coverage to 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 radio access technologies to provide coverage to various geographic coverage areas 110.

[0070] 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 time-aligned. For asynchronous operation, base stations 105 can have different frame timing, and transmissions from different base stations 105 may not be time-aligned in some examples. The techniques described herein can be used for both synchronous and asynchronous operation.

[0071] Some UE 115 devices (such as MTC or IoT devices) can be low-cost or low-complexity devices and 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 may include communication from devices that have integrated sensors or meters to measure or capture information and relay such information to a central server or application that uses the information or presents it to people interacting with the application. Some UE 115 devices may be designed to collect information or automate the behavior of machines or other devices. Examples of applications for MTC devices include: smart metering, inventory monitoring, water level monitoring, equipment monitoring, healthcare monitoring, wilderness survival monitoring, weather and geographic event monitoring, queue management and tracking, remote security sensing, physical access control, and transaction-based commercial toll collection.

[0072] Some UEs 115 can be configured to operate in reduced-power modes, 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 can be performed at reduced peak rates. Other power-saving techniques for UEs 115 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 UEs 115 can be configured to operate using a narrowband protocol type associated with a defined portion or range (e.g., a subcarrier or resource block (RB) set) within the carrier, within the carrier's guard band, or outside the carrier.

[0073] Wireless communication system 100 may be configured to support ultra-reliable communication or low latency communication, or various combinations thereof. For example, wireless communication system 100 may be configured to support ultra-reliable low latency communication (URLLC) or mission-critical communication. UE 115 may be designed to support ultra-reliable, low latency, or mission-critical functions (e.g., mission-critical functions). Ultra-reliable communication may include private or group communication and may be supported by one or more mission-critical services, such as Mission-Critical Talk-to-Talk (MCPTT), Mission-Critical Video (MCVideo), or Mission-Critical Data (MCData). Support for mission-critical functions may include prioritization of services, and mission-critical services may be used for public safety or general commercial applications. The terms ultra-reliable, low latency, mission-critical, and ultra-reliable low latency are used interchangeably herein.

[0074] In some examples, UE 115 may also be able to communicate directly with other UE 115 on a device-to-device (D2D) communication link 135 (e.g., using a peer-to-peer (P2P) or D2D protocol). One or more UE 115s utilizing D2D communication may 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 be unable to receive transmissions from base station 105 for other reasons. In some examples, the group of UE 115s communicating via D2D communication may utilize a one-to-many (1:M) system, where each UE 115 transmits to the other UE 115s 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 the individual UE 115s without involving base station 105.

[0075] In some systems, the D2D communication link 135 may be an example of a communication channel (such as a sidelink communication channel) between vehicles (e.g., UE 115). In some examples, vehicles may communicate using vehicle-to-vehicle (V2X) communication, vehicle-to-vehicle (V2V) communication, or some combination of these communications. Vehicles may signal information related to traffic conditions, signaling, weather, safety, emergencies, or any other information relevant to the V2X system. In some examples, vehicles in a V2X system may communicate via vehicle-to-network (V2N) communication through one or more network nodes (e.g., base station 105) with roadside infrastructure (such as roadside units), or with the network, or with both.

[0076] Core network 130 provides 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). The EPC or 5GC may 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 (e.g., a Serving Gateway (S-GW), Packet Data Network (PDN) Gateway (P-GW), or User Plane Function (UPF)) routing packets or interconnecting to external networks. The control plane entity manages non-access stratum (NAS) functions, such as mobility, authentication, and bearer management of UE 115 served by base station 105 associated with core network 130. User IP packets can be delivered through the user plane entity, which provides IP address allocation and other functions. The user plane entity may be connected to one or more network operator IP services 150. The IP service 150 may include access to the Internet, intranet, 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 each UE 115 through one or more other access network transport entities 145, which may be referred to as a radio headend, smart radio headend, or transmit / receive point (TRP). Each access network transport entity 145 may include one or more antenna panels. In some examples, 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 in the range of, for example, 300 MHz to 300 GHz. For example, a 300 MHz to 3 GHz band is called a UHF band or decimeter band because the wavelength range is from about 1 decimeter to 1 meter. UHF waves can be blocked or redirected by buildings and environmental features, but these waves can penetrate various structures sufficiently for macrocells to provide service to UE 115 located indoors. Compared to transmissions using smaller frequencies and longer waves in the high 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 ranges (e.g., less than 100 km).

[0079] The wireless communication system 100 can also operate in the ultra-high frequency (SHF) zoning using a frequency band from 3 GHz to 30 GHz (also known as the centimeter band) or in the extremely high frequency (EHF) zoning using a spectrum (e.g., from 30 GHz to 300 GHz) (also known as the millimeter band). In some examples, the wireless communication system 100 can support millimeter-wave (mmW) communication between the UE 115 and the base station 105, and the EHF antennas of the corresponding devices can be smaller and more closely spaced than UHF antennas. In some examples, this can facilitate the use of antenna arrays within the device. However, the propagation of EHF transmissions may suffer even greater atmospheric attenuation and 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 may utilize both licensed and unlicensed radio spectrum bands. For example, wireless communication system 100 may employ licensed assisted access (LAA), LTE unlicensed (LTE-U) radio access technology, or NR technology in unlicensed frequency bands, such as the 5 GHz Industrial, Scientific, and Medical (ISM) band. When operating in unlicensed radio spectrum bands, devices (such as base station 105 and UE 115) may employ carrier sensing for collision detection and avoidance. In some examples, operation in unlicensed frequency bands may be based on carrier aggregation configuration (e.g., LAA) in coordination with component carriers operating in licensed frequency bands. Operation in unlicensed spectrum may include downlink transmissions, uplink transmissions, P2P transmissions, or D2D transmissions, etc.

[0081] Base station 105 or UE 115 may be equipped with multiple antennas that can be used to employ technologies 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 that can 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 several rows and columns of antenna ports that base station 105 can use to support beamforming for communication with UE 115. Similarly, UE 115 may have one or more antenna arrays that can support various MIMO or beamforming operations. Additionally or alternatively, the antenna panel may support radio frequency beamforming for signals transmitted via the antenna ports.

[0082] Base station 105 or UE 115 can use MIMO communication to leverage multipath signal propagation and improve spectral efficiency by transmitting or receiving multiple signals via different spatial layers. This technique is known as spatial multiplexing. For example, a transmitting device may transmit multiple signals via different antennas or different combinations of antennas. Similarly, a receiving device may receive multiple signals via different antennas or different combinations of antennas. Each of the multiple signals may be referred to as a separate spatial stream and may carry bits associated with the same data stream (e.g., the same codeword) or different data streams (e.g., different codewords). Different spatial layers may be associated with different antenna ports used for channel measurement and reporting. MIMO techniques include single-user MIMO (SU-MIMO), where multiple spatial layers are transmitted to the same receiving device; and multi-user MIMO (MU-MIMO), where 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, UE 115) to shape 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 some orientations of the antenna array experience constructive interference, while others experience destructive interference. Adjustments to the signals transmitted via the antenna elements may include the transmitting or receiving device applying amplitude offset, phase offset, or both to the signals carried via the antenna elements associated with that device. The adjustments associated with each antenna element may be defined by a beamforming weight set associated with a particular orientation (e.g., relative to the antenna array of the transmitting or receiving device, or relative to another orientation).

[0084] Base station 105 or UE 115 may use beamsweeping 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. Transmissions in different beam directions may be used (e.g., by the transmitting device (such as base station 105) or the receiving device (such as UE 115)) to identify the beam direction that base station 105 will use for later transmission or reception.

[0085] Some signals (such as data signals associated with a receiving device) may be transmitted by base station 105 in a single beam direction (e.g., the direction associated with the 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 signals received by UE 115 with high signal quality or other acceptable signal quality.

[0086] In some examples, transmissions performed by a device (e.g., by base station 105 or UE 115) may be performed using multiple beam directions, and the device may use a combination of digital precoding or radio frequency beamforming to generate combined beams for transmission (e.g., from base station 105 to UE 115). UE 115 may report feedback indicating precoding weights for one or more beam directions, and this feedback may correspond to a configured number of beams across the system bandwidth or one or more subbands. Base station 105 may transmit reference signals that can be precoded or unprecoded (e.g., cell-specific reference signals (CRS), channel state information reference signals (CSI-RS)). UE 115 may provide feedback for beam selection, which may be a precoding matrix indicator (PMI) or codebook-based feedback (e.g., multi-panel type codebook, linear combination type codebook, port selection type codebook). Although these techniques are described with reference to signals transmitted by base station 105 in one or more directions, UE 115 may use similar techniques to transmit signals multiple times in different directions (e.g., to identify the beam direction used by UE 115 for subsequent transmission or reception) or to transmit signals in a single direction (e.g., to transmit data to a receiving device).

[0087] A receiver device (e.g., UE 115) may attempt multiple receive configurations (e.g., directional listening) when receiving various signals (such as synchronization signals, reference signals, beam selection signals, or other control signals) from base station 105. For example, the receiver device may attempt multiple receive directions by: receiving via different antenna subarrays; processing received signals according to different antenna subarrays; receiving according to different sets of receive beamforming weights applied to signals received at multiple antenna elements of the antenna array (e.g., different directional listening weight sets); or processing received signals according to different sets of receive beamforming weights applied to signals received at multiple antenna elements of the antenna array, any of which may be referred to as "listening" according to different receive configurations or receive directions. In some examples, the receiver device may use a single receive configuration to receive along a single beam direction (e.g., when receiving a data signal). The single receive configuration may be aligned on a beam direction determined based on listening according to different receive configuration directions (e.g., a beam direction determined to have high signal strength, high signal-to-noise ratio (SNR), or other acceptable signal quality based on listening according to multiple beam directions).

[0088] 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 performs packet segmentation and reassembly for communication on logical channels. The Media Access Control (MAC) layer performs priority handling and multiplexes logical channels into transport channels. The MAC layer can also use error detection, error correction, or both to support MAC layer retransmissions 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 between the UE 115 and the base station 105 or core network 130 that support user plane data radio bearers. At the physical layer, transport channels can be mapped to physical channels.

[0089] 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 used to increase the likelihood of correctly receiving data on communication link 125. HARQ may 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 MAC layer throughput in poor radio conditions (e.g., low signal-to-noise ratio conditions). In some examples, the device may support simultaneous time-slot HARQ feedback, where the device can provide HARQ feedback in a specific time slot for data received in previous symbols within that time slot. In other cases, the device may provide HARQ feedback in subsequent time slots or according to some other time interval.

[0090] UE 115 can operate according to various states or modes used for communicating with the network. As an example, the UE can operate in an RRC idle state (e.g., RRC_idle), an RRC inactive state (e.g., RRC_inactive), and / or an RRC connected state (e.g., RRC_connected). UE 115 can switch between these states or modes, for example, based on its communication traffic. In the RRC idle state (which may be referred to as idle mode), UE 115 may not be registered to a cell and may accordingly lack an access layer (AS) context, and UE 115 may therefore not have (e.g., via base station 105) an active RRC connection established with the network. In idle mode, UE 115 can periodically wake up to monitor channels for paging or other signaling, and the mobility of UE 115 can be managed by UE 115 when performing measurements on one or more cells. In the RRC connected state (which may be referred to as connected mode), UE 115 may have an established RRC connection (e.g., with 5GC), where UE 115 may store AS context. Here, UE 115 may belong to a known cell and may be identified using the Cell Radio Network Temporary Identifier (C-RNTI) assigned to UE 115. When in connected mode, UE 115 may monitor messages transmitted by the network, which may include monitoring various channels (e.g., paging channels, control channels, etc.).

[0091] The RRC inactive state can be used to reduce signaling overhead and can provide an intermediate mode (e.g., between idle and connected) that can also be used to reduce latency when transitioning to another mode (e.g., to connected mode). UE115 can periodically wake up while in inactive mode to monitor paging messages from the network, and in some cases, UE115 can execute random access procedures to move to connected mode and communicate with the network.

[0092] In the wireless communication system 100, UE 115 can connect to an LTE cell in a non-autonomous operating mode. UE 115 can support dual connectivity with both NR and LTE. Additionally, the 5G dual-subscriber identity module of UE 115 (e.g., a telephone) can support two subscriptions. When operating in non-autonomous mode, UE 115 can be configured with a first set of frequency bands for a first subscription and a second set of frequency bands for a second subscription. In some examples, the UE hardware can be designed such that the first frequency band on the first subscription and the second frequency band on the second subscription have the same downlink path. For example, the first and second frequency bands may have the same downlink path (e.g., sharing common resources), resulting in complete disconnection of the first frequency band during paging operations on the second frequency band.

[0093] One or more aspects of this disclosure allow UE 115 to determine that the frequency band combination is not fully concurrent, and may enable UE 115 to perform full decoupling when communicating using that frequency band combination. In some examples, UE 115 may identify a first set of frequency bands associated with a first subscription and a second set of frequency bands associated with a second subscription. In some examples, the second subscription may be different from the first subscription. UE 115 may determine that the first frequency band from the first set and the second frequency band from the second set share a set of RF front-end resources (e.g., the same downlink path from the UE's RF front-end components). That is, UE 115 may determine that the first and second frequency bands are associated with a shared downlink path. UE 115 may then suppress communication on a third frequency band associated with a subcomponent carrier from the first set (and associated with the first subscription), while communicating on the remaining set of frequency bands from the first set and the second set of frequency bands (e.g., excluding the third frequency band). In some examples, the third frequency band may be different from the first and second frequency bands. UE115 can suppress communication based on the determination that the first and second frequency bands share a set of radio frequency front-end resources and that the third frequency band is associated with a sub-component carrier. Note that a frequency band can also be described as an RF band, and these terms can be used interchangeably. Thus, references to the first or second frequency band herein can also be described as the first RF band or the second RF band, respectively.

[0094] Figure 2 Examples of a wireless communication system 200, which supports techniques for enhancing the performance of user equipment used in the operation of a multi-subscriber identification module, are described according to various aspects of this disclosure. In some examples, the wireless communication system 200 may implement various aspects of the wireless communication system 100. The wireless communication system 200 may include base station 205-a, base station 205-b, and UE 215, which may be as described in reference... Figure 1 Examples of base station 105 and UE 115 are described. Each base station 105 serves a geographic coverage area. In some cases, one or more geographic coverage areas served by base stations 205-a and 205-b may overlap. In some cases, UE 215 may be configured with multi-subscriber identification module functionality and may be configured to support improved multi-subscription communication by communicating a subset of configured frequency bands. For example, the UE hardware may be designed such that a first frequency band on a first subscription and a second frequency band on a second subscription share the same downlink path. In such cases, UE 215 may suppress communication on frequency band combinations that would cause complete disengagement to improve communication.

[0095] exist Figure 2In the example, UE 215 can operate in a non-autonomous mode. That is, UE 215 can support a non-autonomous architecture where different radio access technologies can be utilized concurrently or simultaneously by different serving base stations. For example, a non-autonomous UE can be anchored to or connected to a first cell while facilitating communication with a second cell. Additionally or alternatively, a non-autonomous UE can be anchored to or connected to a cell associated with a first radio access technology (e.g., LTE) while facilitating communication with a cell associated with a second radio access technology (e.g., NR). In some cases, the cells associated with each radio access technology can be contained at a single base station or can be located at separate base stations.

[0096] In some examples, UE 215 may support multiple subscriptions. In some cases, UE 215 may be an example of a dual subscriber identity module or a multi-subscriber identity module. For example, UE 215 may include a first subscriber identity module 207 (SIM 207) and a second subscriber identity module 210 (SIM 210). The first subscriber identity module 207 may provide a first subscription (which may be referred to as the default data SIM (DDS)), and the second subscriber identity module 210 may provide a second subscription (which may be referred to as a non-DDS). In some cases, one or both subscriptions (e.g., the first subscriber identity module 207 and the second subscriber identity module 210) may be configured to support a non-self-contained architecture. In some instances, the first subscriber identity module 207 and the second subscriber identity module 210 may camp on a first cell. That is, UE 215 may communicate with the first cell via the first subscription and may communicate with the first cell concurrently or simultaneously via the second subscription. In some cases, the first cell may be supported by different base stations 105, or the first cell may be supported by the same base station 105, or any combination thereof. In some cases, the first cell may be associated with a radio access technology. In some cases, each network may be supported by different base stations 105, or each network may be supported by the same base station 105, or any combination thereof. In one example, base stations 205-a and 205-b may support a non-self-contained 5G network. In some cases, a network may refer to a cell.

[0097] Because UE 215 is configured to have two subscriptions, UE 215 can support communication with two base stations 205 (e.g., base station 205-a and base station 205-b) simultaneously. As depicted herein, UE 215 can be configured to support dual connectivity or other non-self-reliant communication schemes. In one example, UE 215 can communicate with base station 205-a associated with a first cell (e.g., anchored cell) of a radio access technology (e.g., a 5G network, LTE network, or 4G network) via communication link 220. For example, UE 215 can establish a connection with base station 205-a via communication link 220 for both the first and second subscriptions. As depicted herein, UE 215 can establish a connection with base station 205-b via communication link 225. Additionally or alternatively, because UE 215 is configured to support dual connectivity, UE 215 can support communication with two base stations 205 (e.g., two networks) simultaneously.

[0098] In some aspects, UE 215 can support dual subscriber identity module dual standby mode (dual SIM dual standby). Dual SIM dual standby mode enables the device to receive on two different subscriber identity module subscriptions. Disconnection features allow UE 215 to receive paging on one subscription while remaining active in the other (e.g., maintaining or initiating packet-switched calls in the second subscription). Additionally or alternatively, dual reception features enable simultaneous reception on two different subscriptions using two different technologies. In some examples, dual reception may differ from dual active mode. Specifically, dual active mode may support single transmission. In dual SIM dual standby mode, UE 215 can avoid disconnection and receive using two different technologies even when they are operating in different frequency bands. This may further depend on the operating mode of UE 215.

[0099] In some examples, UE 215 may support dual-receive full-concurrency mode. In such examples, UE 215 may support the elimination of disengagement operations from a first radio access technology in data traffic to a second radio access technology in idle state. In some examples, UE 215 may be configured to monitor paging on the first subscription without interfering with communication on the second subscription. For example, NR frequency range 1 (FR1) may utilize the primary receive path (PRx1), diversity receive path (DRx1), and transmit path (TX) on the first subscription, and LTE may utilize another primary receive path (PRx2) or different resources for idle mode operation on the second subscription. Thus, NR may have full data reception capability as well as full MIMO support capability. In some examples, NR FR1 throughput may be unaffected, and communication may be within a certain statistical variance. In some examples, UE 215 may support diversity sharing mode (e.g., diversity disengagement). In diversity disengagement mode, the first subscription supporting data traffic may lose the secondary RF chain when technology 2 (tech 2) wakes up for idle operation. Diversity disengagement can occur due to limitations on the RF front-end and a particular frequency band combination. For example, LTE may utilize PRx1 and Tx, while GSM may utilize DRx1. In some examples, LTE may lose receive diversity (RxD) and MIMO capabilities during the duration of the disengagement.

[0100] Additionally or alternatively, the UE may operate under either a fully off-line (non-dual reception) or hybrid fallback mode. In a fully off-line example, data traffic from the first subscription may be off-lined to the second subscription in an idle state. For example, in fully off-line mode, NR traffic on the first subscription may lose RF resources to GSM resources on the second subscription during the duration of activity on the second subscription. A fully off-line or hybrid fallback mode may be invoked when the GSM experiences poor paging performance (e.g., when the UE 215 detects three consecutive paging decoding failures or three transceiver resource managers (TRMs) refusing paging decoding). In such cases, the UE 215 may fall back to the off-line mode to improve paging performance. Additionally or alternatively, a fully off-line or hybrid fallback mode may be invoked when the GSM enters an access or traffic state for mobile-originating / mobile-terminating voice calls, mobile-originating / mobile-terminating message transmission and reception on traffic channels, and GSM Location Area Update (LAU). In some examples, when the technology enters a capture state, a full detour or hybrid fallback mode can be invoked.

[0101] In some systems, UE 215 can connect to LTE cells in a non-autonomous mode. Non-autonomous mode can refer to the deployment of a first radio access technology (e.g., 5G NR) on the control plane that can use another radio access technology (e.g., 4G LTE), while the first radio access technology handles user plane functions. Alternatively, autonomous mode can refer to a single radio access technology used for both control plane and user plane functions. In some examples, UE 215 can support dual connectivity with both NR and LTE. Additionally, a dual-SIM UE (e.g., a phone) can have two subscriptions.

[0102] When operating in non-autonomous mode, UE 215 may be identified or otherwise configured with a first set of frequency bands for a first subscription and a second set of frequency bands for a second subscription. In some cases, the UE 215 hardware may be designed such that the first frequency band on the first subscription and the second frequency band on the second subscription have the same downlink path or resource set. In some examples, the UE hardware may support autonomous or non-autonomous multi-subscriber identification module configuration. In some examples, the first subscription at UE 215 may support non-autonomous or autonomous mode, while the second subscription at UE 215 may support autonomous mode (e.g., using NR / LTE / WCDMA / GSM / 1x). For example, the first frequency band on the first subscription and the second frequency band on the second subscription may share the same RF front-end resource set. As an illustrative example, UE 215 may be configured with the LTE B66 band, the LTE B2 band (which may correspond to the subcomponent carrier of a carrier aggregation scheme), and the NR n71 band on the first subscription. UE 215 may be further configured with a WCDMA B2 band on a second subscription. In this example, the n71 band and the WCDMA B2 band may have or share the same RF front-end resources and / or downlink paths, resulting in complete decoupling of the n71 band, for example, during paging operations on the WCDMA B2 band. In such a scenario, complete decoupling may be implemented on UE 215 to decode paging on the WCDMA B2 band. Such complete decoupling of the n71 band may affect communication (e.g., high-throughput communication using NR technology on the n71 band), potentially leading to degraded performance. Additionally or alternatively, complete decoupling at UE 215 may disrupt the multi-subscriber identification module configuration. The performance impact of decoupling at UE 215 may result in a degraded user experience.

[0103] However, in some cases, LTE B2 (downlink subcomponent carrier) can be removed (e.g., when UE 215 is configured with bands B66 and n71 on the first subscription and band WB2 on the second subscription). n71 and WB2 can use different ports (e.g., SDR ports), and thus n71 can be fully concurrent with WB2. Therefore, to mitigate communication interruptions between a UE (such as UE 215) in non-autonomous operation mode and the cell, UE 215 can be configured to support improved communication. As an example, to reduce latency and improve resource efficiency, UE 215 can determine that the band combination is not fully concurrent and that the UE may perform full disengagement while communicating using that band combination. UE 215 can then suppress communication on one of the bands from the determined band combination. In some examples, if an LTE sub-component carrier is configured (which may or may not be activated) for the first subscription, UE 215 can discard the sub-component carrier, allowing UE 215 to perform paging operations on the second subscription without complete disengagement. In some examples, UE 215 can de-prioritize a frequency band combination that, when activated, causes the UE to switch to complete disengagement mode. In some examples, UE 215 can determine a frequency band combination that causes UE 215 to switch to complete disengagement mode. In such examples, UE 215 can remove advertisements for such combinations from the capability report.

[0104] According to one or more aspects of this disclosure, UE 215 can be configured to operate in a fully concurrent mode to enhance throughput or performance. In some cases, when configured with, for example, NR sub-6 GHz bands, operating in fully concurrent mode can enhance performance at UE 215, and NR sub-6 GHz bands support higher bandwidth or throughput. To achieve full concurrency, UE 215 can identify which bands or carrier aggregations or dual connectivity combinations are fully concurrent and which bands are associated with full decoupling at UE 215. For example, UE 215 can identify a first set of bands associated with a first subscription (SIM 207) and a second set of bands associated with a second subscription (SIM 210), which is different from the first subscription. UE 215 can then determine that a first band from the first set of bands and a second band from the second set of bands share a set of RF front-end resources, wherein a third band from the first set of bands is associated with a subcomponent carrier of a multi-carrier communication scheme. UE 215 may suppress communication on a third frequency band while simultaneously communicating on the remaining frequency band set from the first frequency band set and the second frequency band set (e.g., simultaneously). For example, UE 215 may suppress communication based on the determination that the first frequency band from the first frequency band set and the second frequency band from the second frequency band set share a set of RF front-end resources and that the third frequency band is associated with a sub-component carrier.

[0105] In some examples, if UE 215 determines that a sub-component carrier is configured but not activated, UE 215 may discard the sub-component carrier, causing UE 215 to perform a full disconnect to read paging on the second subscription (SIM 210). For example, UE 215 may determine that a third frequency band is configured as a sub-component carrier. UE 215 may further determine that there is no control signaling to activate the third frequency band associated with the sub-component carrier. In such examples, UE 215 may suppress communication on the third frequency band, which may include discarding the third frequency band based on the absence of control signaling to activate the third frequency band associated with the sub-component carrier.

[0106] Depending on one or more aspects, UE 215 may discard an activated sub-component carrier. For example, UE 215 may receive control signaling from base station 205-a to activate a third frequency band associated with a sub-component carrier on a first subscription (SIM 207). UE 215 may determine, based on receiving this control signaling, that the third frequency band associated with the sub-component carrier is activated. In such an example, UE 215 may discard the third frequency band based on determining that a third frequency band associated with a sub-component carrier shares an RF front-end resource set with a first frequency band from a first frequency band set and a second frequency band from a second frequency band set. UE 215 may discard the sub-component carrier locally or by reporting compensated measurements to cause the network to deconfigure the sub-component carrier. For example, UE 215 may report compensated measurements of the third frequency band (e.g., to base station 205-a) based on determining that a third frequency band associated with a sub-component carrier shares an RF front-end resource set with a first frequency band from a first frequency band set and a second frequency band from a second frequency band set is activated. In some respects, UE 215 can discard the third band based on reported compensated measurements.

[0107] The techniques described herein allow UE 215 to identify the number of resource grants associated with a sub-component carrier based on the activation of the third frequency band. In some examples, UE 215 may discard the third frequency band based on the identified number of resource grants associated with the sub-component carrier. That is, UE 215 may determine whether to discard an activated sub-component carrier based on resource block grants on the sub-component carrier that prevent full concurrency at UE 215.

[0108] In some examples, UE 215 may reduce the priority of a third frequency band from the first frequency band set based on determining a shared RF front-end resource set for a first frequency band from the first frequency band set and a second frequency band from the second frequency band set. For example, UE 215 may reduce the priority of carrier aggregation combinations (including sub-component carriers) that cause UE 215 to perform a full disengagement operation. In such cases, UE 215 may not transmit measurements or compensated measurements for that frequency band. That is, UE 215 may report compensated measurements for a third frequency band (e.g., corresponding to a sub-component carrier) from the first frequency band set based on determining a shared RF front-end resource set for a first frequency band from the first frequency band set and a second frequency band from the second frequency band set. Alternatively, UE 215 may suppress the reporting of measurements for the first frequency band from the first frequency band set based on determining a shared RF front-end resource set for a first frequency band from the first frequency band set and a second frequency band from the second frequency band set.

[0109] In some examples, UE 215 may simultaneously communicate on the remaining set of frequency bands for the first subscription of UE 215 and the second set of frequency bands for the second subscription of UE 215, based on suppressing communication on the first frequency band associated with the subcomponent carrier. Additionally or alternatively, UE 215 may determine that a combination of the first and third frequency bands from the first frequency band set and the second frequency band from the second frequency band set can be associated with a complete disengagement operation using the second subscription (SIM 207) at UE 215.

[0110] In some examples, UE 215 may transmit a capability report to base station 205-a excluding frequency band combinations (e.g., the first and third frequency bands) that may be associated with complete disengagement. UE 215 may transmit the capability report based on determining a shared RF front-end resource set for the first frequency band from the first frequency band set and the second frequency band from the second frequency band set. That is, UE 215 may identify a set of multiple combinations of the first and second frequency band sets used for communicating with the base station. UE 215 may then transmit a capability report including the remaining combinations from the set of multiple combinations of the first and second frequency band sets. Because UE 215 operates in full-concurrency mode, the techniques described herein thereby provide improved throughput and performance. Additionally or alternatively, the techniques described herein provide improved power usage due to fewer retransmissions, and thus an enhanced user experience. Furthermore, these techniques avoid potentially costly and undesirable modifications to the hardware of UE 215.

[0111] Figure 3 Examples of hardware configuration 300 supporting techniques for enhancing the performance of user equipment (UE) for multi-subscriber identification module operation, according to various aspects of this disclosure, are described. In some examples, hardware configuration 300 may implement aspects of wireless communication system 100 and wireless communication system 200. Hardware configuration 300 may be included in a UE, which may be as described in reference... Figure 1 Examples or references to the described UE 115 Figure 2 The UE 215 is described. Hardware configuration 300 may be included in the UE, which is configured to support multi-subscriber identification module functionality.

[0112] As in Figure 3 As depicted in the example, hardware configuration 300 includes hardware section 315 and RF front-end 310. RF front-end 310 may be coupled to a first antenna 305-a and a second antenna 305-b. Although two antennas 305 are described, hardware configuration 300 may include a different number of antennas 305. In some examples, RF front-end 310 may be configured to use the first antenna 305-a and the second antenna 305-b to transmit or receive communications. Although in Figure 3The example depicts two antennas, but it will be understood that any number of antennas may be coupled to the RF front end 310. The hardware section 315 may be an example of one or more processors and / or a system-on-a-chip (SoC) (e.g., an SoC with a certain Reduced Instruction Set Computing (RISC) machine (ARM) architecture). The hardware section may provide functionality for transmitting and receiving signals, for example, through the RF front end 310.

[0113] In some examples, the UE may be identified or otherwise configured with a first set of frequency bands associated with the first subscription. Additionally or alternatively, the UE may be identified or otherwise configured with a second set of frequency bands associated with a second subscription, which is different from the first subscription. Figure 3 In the example, the UE may be configured with a first frequency band 320, a second frequency band 325, and a third frequency band 330 associated with a first subscription. The UE may also be configured with a fourth frequency band 335 associated with a second subscription. Frequency bands 340 and 345 may be associated with transmissions from the UE (using the first subscription, the second subscription, or both). In some cases, the first frequency band 320 may be associated with a sub-component carrier of a multi-carrier communication scheme (e.g., a downlink sub-component carrier).

[0114] Depending on one or more aspects, the UE may determine that a third frequency band 330 from a first frequency band set and a fourth frequency band from a second frequency band set share a set of RF front-end resources (e.g., DLP1). In one example, the first frequency band 320 may correspond to the LTE B2 band, the second frequency band 325 may correspond to the LTE B66 band, the third frequency band 330 may correspond to the NR n71 band, and the fourth frequency band 335 may correspond to the WCDMA B2 band. In such a case, the UE may determine that the combination of the third frequency band 330 and the fourth frequency band 335 causes the UE to perform a complete disengagement operation because the third frequency band 330 and the fourth frequency band 335 can share the same set of RF front-end resources. It should be noted that the examples of frequency bands described herein are provided for illustrative purposes and should not be considered limiting. That is, other frequency bands associated with other radio access technologies may be possible, and the examples provided herein are some possible frequency bands that can be used.

[0115] When it is determined that the third band 330 and the fourth band 335 share a common RF front-end resource set (e.g., DLP1), the UE may suppress communication on the first band 320, which may also be configured as a downlink subcomponent carrier. For example, when it is determined that the third band 330 and the fourth band 335 share a common RF front-end resource set, the UE may discard communication on the first band 320. In some examples, instead of discarding, the UE may report compensated measurements on the first band 320. By avoiding communication on the first band 320, the UE can avoid a complete de-intervention operation, resulting in enhanced performance. For example, discarding communication on the first band and / or reducing the priority of that communication can free up resources for communication on the fourth band 335, which similarly avoids a complete de-intervention on the third band 330. Specifically, discarding the first band 320 allows different ports (e.g., SDR ports) to be used between two subscriptions, and as a result, the third band 330 and the fourth band 335 can be fully concurrent.

[0116] Figure 4 Examples of process flow 400 in a system supporting techniques for enhancing the performance of user equipment used in the operation of a multi-subscriber identification module, according to various aspects of this disclosure, are explained. In some examples, process flow 400 may implement aspects of wireless communication system 100 and wireless communication system 200. UE 415 may be a reference Figure 1 and 2 The example of UE 115 described herein, and base station 405 may be a reference. Figure 1 and 2 An example of the described base station 105.

[0117] In the following description of process flow 400, operations between base station 405 and UE 415 may be transmitted in a different order than the exemplary order shown. Operations performed by base station 405 or UE 415 may be performed in a different order than the exemplary order shown or at different times. Some operations may also be omitted from process flow 400, or other operations may be added to process flow 400. Furthermore, base station 405 and UE 415 are not limiting, as this disclosure can be associated with any number of different devices.

[0118] At 420, UE 415 may identify a first set of frequency bands associated with the first subscription. UE 415 may also identify a second set of frequency bands associated with a second subscription, which is different from the first subscription. In some examples, the communication state of the first frequency band (or the first set of frequency bands) may include a bi-connectivity mode, and the communication state of the second frequency band (or the second set of frequency bands) may include an idle mode. In some examples, the first subscription may be associated with multi-carrier operation (e.g., carrier aggregation), and the second subscription may be associated with single-carrier operation.

[0119] At 425, base station 405 may optionally transmit control signaling to UE 415. UE 415 may receive control signaling from base station 405 to activate a frequency band associated with a sub-component carrier. For example, a third frequency band from the first frequency band set (associated with the first subscription) may be activated as a sub-component carrier in a multi-carrier communication scheme or as a deployed sub-component carrier. In some examples, the sub-component carrier may be a downlink sub-component carrier.

[0120] At 430, UE 415 may optionally determine that the third frequency band is configured as a sub-component carrier. In some examples, UE 415 may additionally determine that there is no control signaling to activate the third frequency band associated with the sub-component carrier. Additionally or alternatively, UE 415 may determine that the third frequency band associated with the sub-component carrier is activated based on the receipt of such control signaling.

[0121] At 435, UE 415 may determine that at least a first frequency band from a first set of frequency bands and at least a second frequency band from a second set of frequency bands share the same set of RF front-end resources. As described herein, the first and second frequency bands sharing the same RF front-end resources may result in a complete disengagement operation, which could affect communication efficiency at UE 415. Thus, UE 415 may implement techniques to achieve full concurrency between frequency bands with different subscriptions, such as dropping another frequency band from the first subscription (e.g., from the first set of frequency bands) or reducing the priority of another frequency band. Here, a third frequency band corresponding to a sub-component carrier may be dropped or reduced in priority.

[0122] At 440, UE 415 may optionally transmit a capability report excluding multi-carrier combinations to base station 405, which may involve excluding combinations of the first and third frequency bands based on determining a shared RF front-end resource set of a first frequency band from a first frequency band set and a second frequency band from a second frequency band set. In other words, the first and third frequency bands may be associated with multi-carrier operation (e.g., carrier aggregation), and due to resource conflicts arising between the first and second frequency bands, UE 415 may exclude combinations of the first and third frequency bands (e.g., both from the first frequency band set and associated with the same subscription) in the capability report to base station 405. Additionally or alternatively, UE 415 may identify a set of combinations of the first and third frequency band sets used for communicating with the base station. In some examples, combinations of the first and second frequency bands may be included in this set of combinations. UE 415 may then transmit a capability report including the remaining combinations in the set of combinations of the first and second frequency band sets.

[0123] In some examples, at 445, UE 415 may report compensated measurements of a third frequency band based on the determination that at least a first frequency band from a first frequency band set and at least a second frequency band from a second frequency band set share a set of RF front-end resources and that a third frequency band associated with a subcomponent carrier is activated. In some examples, the third frequency band may be discarded based on the reported compensated measurements.

[0124] In some cases, UE 415 may identify the number of resource grants associated with the sub-component carriers based on the activation of the third frequency band. In some examples, the third frequency band may be discarded based on the identified number of resource grants associated with the sub-component carriers.

[0125] Additionally or alternatively, UE 415 may reduce the priority of a third frequency band from the first frequency band set based on determining that a first frequency band from the first frequency band set and a second frequency band from the second frequency band set share a set of RF front-end resources. UE 415 may then report compensated measurements of the third frequency band from the first frequency band set based on determining that a first frequency band from the first frequency band set and a second frequency band from the second frequency band set share a set of RF front-end resources (e.g., in 445). Although not in Figure 4 As depicted in the example, it is understood that UE 415 may suppress the reporting of measurements of a third frequency band from the first frequency band set based on determining that the first frequency band from the first frequency band set and the second frequency band from the second frequency band set share a set of RF front-end resources.

[0126] At 450, UE 415 may communicate with base station 405. For example, UE 415 may suppress communication on a third frequency band based on suppressing communication on a first frequency band associated with a sub-component carrier, while simultaneously communicating on the remaining frequency band set for the UE's first subscription (e.g., the remaining frequency band set from the first frequency band set) and the second frequency band set for the UE's second subscription. In some examples, suppressing communication on the third frequency band may be based on determining that the first frequency band from the first frequency band set and the second frequency band from the second frequency band set share an RF front-end resource set and that the third frequency band is associated with a sub-component carrier. In some aspects, UE 415 may discard the third frequency band associated with a sub-component carrier based on determining that the first frequency band from the first frequency band set and the second frequency band from the second frequency band set share an RF front-end resource set and that the first frequency band is activated. When communicating on a frequency band (e.g., a frequency band excluding the third frequency band), UE415 may simultaneously communicate on the set of remaining frequency bands for the UE's first subscription (e.g., the set of remaining frequency bands from the first frequency band set) and the set of second frequency bands for the UE's second subscription.

[0127] Figure 5A block diagram 500 of an apparatus 505 supporting techniques for enhancing the performance of user equipment for operation of a multi-subscriber identification module, according to various aspects of this disclosure, is shown. Apparatus 505 may be an example of various aspects of a UE 115 as described herein. Apparatus 505 may include a receiver 510, a transmitter 515, and a communications manager 520. Apparatus 505 may also include a processor. Each of these components may be in communication with each other (e.g., via one or more buses).

[0128] Receiver 510 may provide means for receiving information, such as packets, user data, control information, or any combination thereof, associated with various information channels (e.g., control channels, data channels, information channels related to technologies for enhancing the performance of user equipment used in the operation of multi-subscriber identification modules). The information may be transmitted to other components of device 505. Receiver 510 may utilize a single antenna or a collection of multiple antennas.

[0129] Transmitter 515 may provide means for transmitting signals generated by other components of device 505. For example, transmitter 515 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, information channels related to technologies for enhancing the performance of user equipment used in the operation of the multi-subscriber identification module). In some examples, transmitter 515 may be co-located with receiver 510 in a transceiver module. Transmitter 515 may utilize a single antenna or a collection of multiple antennas.

[0130] The communication manager 520, receiver 510, transmitter 515, or various combinations thereof, or various components thereof, may be examples of means for performing various aspects of the techniques described herein for enhancing the performance of user equipment for operation of a multi-subscriber identification module. 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.

[0131] 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 a communication management circuitry system). This 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 means 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).

[0132] Additionally or alternatively, in some examples, the communication manager 520, receiver 510, transmitter 515, or various combinations or components thereof may be implemented by code executed by a processor (e.g., as communication management software or firmware). If implemented by code executed by a processor, the functionality of the communication manager 520, receiver 510, transmitter 515, or various combinations or components thereof may be performed by a general-purpose processor, DSP, central processing unit (CPU), ASIC, FPGA, or any combination of these or other programmable logic devices (e.g., means configured or otherwise supported for performing the functions described in this disclosure).

[0133] In some examples, the communication manager 520 may be configured to use or otherwise cooperate with the receiver 510, transmitter 515, or both to perform various operations (e.g., receiving, monitoring, transmitting). For example, the communication manager 520 may receive information from the receiver 510, send information to the transmitter 515, or be integrated with the receiver 510, transmitter 515, or both to receive information, transmit information, or perform various other operations described herein.

[0134] According to the examples disclosed herein, the communication manager 520 may support wireless communication at the UE. For example, the communication manager 520 may be configured or otherwise support means for identifying a first set of frequency bands associated with a first subscription. The communication manager 520 may be configured or otherwise support means for identifying a second set of frequency bands associated with a second subscription, which is different from the first subscription. The communication manager 520 may be configured or otherwise support means for determining that a first frequency band from the first set of frequency bands and a second frequency band from the second set of frequency bands share a set of radio frequency front-end resources. The communication manager 520 may be configured or otherwise support means for suppressing communication on a third frequency band from the first set of frequency bands, the third frequency band being associated with a sub-component carrier of a multi-carrier communication scheme, wherein the suppression of communication on the third frequency band is based on determining that the first and second frequency bands share the set of radio frequency front-end resources and that the third frequency band is associated with the sub-component carrier. The communication manager 520 can be configured or otherwise supports means for communicating on the remaining frequency band set from the first frequency band set and the second frequency band set based on suppressing communication on the third frequency band.
