Abstract

A method of wireless communication performed by a user equipment (UE) includes receiving one or more configuration messages indicating configuration of the UE with a first component carrier (CC) for a first subscription corresponding to a first subscriber identity module (SIM) of the UE and at least a second CC. The method further includes performing one or more operations associated with a second subscription corresponding to the second SIM of the UE during a time interval. During the time interval, communication over the first subscription using the second CC is avoided based on a first throughput associated with the first CC exceeding a second throughput associated with the second CC.

Description

[Technical field]

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS This application claims the benefit of U.S. Patent Application No. 17 / 368,536, filed July 6, 2021, entitled “THROUGHPUT-BASED COMPONENT CARRIER RESOURCE ALLOCATION FOR MULTIPLE SUBSCRIPTIONS OF A USER EQUIPMENT,” which is expressly incorporated herein by reference in its entirety.

[0002] Aspects of the present disclosure relate generally to wireless communication systems and, more particularly, to user equipment (UE) devices that use multiple subscriptions, such as in conjunction with multiple subscriber identity module (MSIM) implementations of the UE. [Background technology]

[0003] Wireless communication networks are widely deployed to provide various communication services such as voice, video, packet data, messaging, broadcasts, etc. These wireless networks may be multiple-access networks capable of supporting multiple users by sharing available network resources. Such networks may be multiple-access networks that support communication for multiple users by sharing available network resources.

[0004] A wireless communication network may include several components. These components may include wireless communication devices, such as base stations (or Node Bs), that can support communication for several user equipments (UEs). The UEs may communicate with the base stations via a downlink and an uplink. The downlink (or forward link) refers to the communication link from the base station to the UE, and the uplink (or reverse link) refers to the communication link from the UE to the base station.

[0005] A base station may transmit data and control information to a UE on the downlink or receive data and control information from a UE on the uplink. On the downlink, transmissions from a base station may experience interference due to transmissions from neighboring base stations or from other wireless radio frequency (RF) transmitters. On the uplink, transmissions from a UE may experience interference from uplink transmissions of other UEs communicating with neighboring base stations or from other wireless RF transmitters. This interference may degrade performance on both the downlink and the uplink.

[0006] As the demand for mobile broadband access continues to increase, more UEs access long-range wireless communication networks, and more short-range wireless systems are deployed in regions, increasing the possibility of interference and network congestion. Research and development continues to evolve wireless technologies to not only meet the growing demand for mobile broadband access, but also to evolve and improve the user experience of mobile communications. Summary of the Invention

[0007] In some aspects of the disclosure, a method of wireless communication performed by a user equipment (UE) includes receiving one or more configuration messages indicating configuration of the UE with a first component carrier (CC) and at least a second CC for a first subscription corresponding to a first subscriber identity module (SIM) of the UE. The method further includes performing one or more operations associated with a second subscription corresponding to the second SIM of the UE during a time interval. During the time interval, communication over the first subscription using the second CC is avoided based on a first throughput associated with the first CC exceeding a second throughput associated with the second CC.

[0008] In some other aspects of the disclosure, an apparatus for wireless communication includes a transmitter and a receiver. The receiver is configured to receive one or more configuration messages indicating configuration of a first CC and at least a second CC for a first subscription corresponding to a first SIM. The receiver is further configured to perform one or more operations associated with a second subscription corresponding to the second SIM during the time interval. One or both of the transmitter or receiver are configured to avoid communication associated with the first subscription using the second CC based on a first throughput associated with the first CC exceeding a second throughput associated with the second CC during the time interval.

[0009] In some other aspects of the disclosure, a non-transitory computer-readable medium stores instructions executable by a processor of a UE to initiate, execute, or control operations. The operations include receiving one or more configuration messages indicating configuration of the UE with a first CC and at least a second CC for a first subscription corresponding to a first SIM of the UE. The operations further include performing one or more operations associated with a second subscription corresponding to a second SIM of the UE during the time interval. During the time interval, communication over the first subscription using the second CC is avoided based on a first throughput associated with the first CC exceeding a second throughput associated with the second CC.

[0010] In some other aspects of the disclosure, an apparatus for wireless communication includes means for transmitting a signal. The apparatus further includes means for receiving one or more configuration messages indicating a configuration of a first CC and at least a second CC for a first subscription corresponding to a first SIM. The means for receiving is configured to perform one or more operations associated with a second subscription corresponding to a second SIM of the UE during a time interval. During the time interval, communication over the first subscription using the second CC is avoided based on a first throughput associated with the first CC exceeding a second throughput associated with the second CC.

[0012] User equipment (UE) devices may use a subscriber identity module (SIM) to enable communication with network devices. For example, the SIM of a UE device may store information identifying a subscription (such as a subscription to a cellular service of a cellular service provider) to enable network devices to route calls and messages to the UE device. SIMs include hardware SIMs (such as SIM cards) as well as other types of SIMs, such as embedded SIMs (eSIMs), which may be implemented using software in some devices.

[0013] Some UE devices include multiple SIMs to enable connection to multiple networks. For example, the multiple SIMs may enable the UE to communicate with wireless communication networks associated with different radio access technologies (RATs). As a particular example, a UE device may include multiple SIMs to support a concurrent RAT (CRAT) scenario in which the UE device can simultaneously communicate with network devices of different RATs.

[0014] In some situations, resource contention may arise between a subscription of one SIM of a UE device and a subscription of another SIM of the UE device. Some UE devices may use a tune-away operation to avoid or mitigate resource contention. In a tune-away operation, one subscription (sometimes called a "victim") may temporarily avoid certain types of communication (e.g., by giving up resources) to avoid a conflict with another subscription (sometimes called an "aggressor"). In some cases, the tune-away operation may reduce device performance, such as by reducing the throughput associated with the victim subscription (e.g., by reducing the amount of bandwidth available to the victim subscription, by delaying the transmission or reception of data packets, or by causing missed or dropped calls).

[0015] Techniques according to some aspects of the present disclosure may select a component carrier (CC) having the lowest throughput for tune-away operation. In some aspects, the UE may store an indication of the throughput of the CC associated with the first subscription corresponding to the first SIM in a throughput database. In response to detecting a resource conflict between the first subscription and the second subscription corresponding to the second SIM, the UE may access the throughput database to identify the CC having the lowest throughput. To avoid or mitigate the resource conflict, the first subscription may avoid communicating using the CC while the second subscription performs one or more operations, thereby increasing resources available to the second subscription during the one or more operations (e.g., by “mitigating” the amount of radio frequency (RF) or baseband processing associated with the first subscription during the one or more operations). By avoiding communicating using the CC, access to one or more of the RF or baseband resources (e.g., processor, memory, or bus) may be increased for the second subscription to mitigate or avoid the resource conflict.

[0016] In some implementations, the one or more operations include an idle mode operation associated with the second subscription that "keeps alive" a network connection associated with the second subscription. For example, the one or more operations may include one or more of monitoring for paging messages, receiving system information block (SIB) messages, or performing network measurements.

[0017] By selecting a CC with the lowest throughput for tune-away operation, performance in a wireless communication system may be improved compared to some other techniques. For example, by selecting the "worst" performing CC based on recent channel conditions or other metrics, performance degradation for the first subscription may be minimized or reduced compared to a technique that selects resources randomly or according to a last-in-first-out (LIFO) or first-in-first-out (FIFO) basis. As a result, the total throughput associated with the UE may be increased while performance degradation for the victim RAT may be reduced compared to a device that selects resources to be relinquished using another technique, such as by randomly selecting resources or by using a LIFO or FIFO technique.

[0018] Some aspects of the present disclosure may be used for wireless communication networks such as code division multiple access (CDMA) networks, time division multiple access (TDMA) networks, frequency division multiple access (FDMA) networks, orthogonal FDMA (OFDMA) networks, single carrier FDMA (SC-FDMA) networks, LTE networks, GSM networks, fifth generation (5G) or new radio (NR) networks (sometimes referred to as "5G NR" networks, systems, or devices), and other communication networks. The terms "network" and "system" described herein may be used interchangeably.

[0019] For example, a CDMA network may implement a radio technology such as universal terrestrial radio access (UTRA), cdma2000, etc. UTRA includes Wideband CDMA (W-CDMA) and Low Chip Rate (LCR). CDMA2000 covers IS-2000, IS-95, and IS-856 standards.

[0020] The TDMA network may implement a radio technology such as, for example, Global System for Mobile Communications (GSM). The 3rd Generation Partnership Project (3GPP) defines standards for the GSM EDGE (Enhanced Data Rates for GSM Evolution) Radio Access Network (RAN), also denoted as GERAN. The GERAN is the radio component of GSM / EDGE, along with the network that connects the base stations (e.g., Ater and Abis interfaces) and the base station controllers (such as the A interface). The radio access network represents the component of the GSM network through which telephone calls and packet data are routed to and from the Public Switched Telephone Network (PSTN) and the Internet to and from the subscriber handsets, also known as user terminals or user equipment (UE). A mobile operator's network may include one or more GERANs, which may be combined with a UTRAN in the case of a UMTS / GSM network. In addition, the operator network may also include one or more LTE networks or one or more other networks. Various different network types may use different Radio Access Technologies (RATs) and RANs.

[0021] OFDMA networks may implement radio technologies such as Evolved UTRA (E-UTRA), Institute of Electrical and Electronics Engineers (IEEE) 802.11, IEEE 802.16, IEEE 802.20, Flash OFDM, etc. UTRA, E-UTRA, and GSM are parts of the Universal Mobile Telecommunications System (UMTS). Specifically, long term evolution (LTE) is a release of UMTS that uses E-UTRA. UTRA, E-UTRA, GSM, UMTS, and LTE are described in documents from an organization named "3rd Generation Partnership Project" (3GPP), and cdma2000 is described in documents from an organization named "3rd Generation Partnership Project 2" (3GPP2). These various radio technologies and standards are known or under development. For example, 3GPP is a collaboration between groups of telecommunications associations that aims to define globally applicable third generation (3G) mobile phone specifications. 3GPP LTE is a 3GPP project that aims to improve the UMTS mobile phone standard. 3GPP may define specifications for next generation mobile networks, mobile systems, and mobile devices. Although the present disclosure may describe some aspects with reference to LTE, 4G, or 5G NR technology, the description is not intended to be limited to a particular technology or application, and one or more aspects described with reference to one technology may be understood to be applicable to another technology. In addition, one or more aspects of the present disclosure may relate to shared access to a wireless spectrum between networks using different radio access technologies or radio air interfaces.

[0022] 5G networks contemplate diverse deployments, diverse spectrum, and diverse services and devices that can be implemented using an OFDM-based unified air interface. To achieve these goals, further enhancements to LTE and LTE-A are being considered in addition to the development of new radio technologies for 5G NR networks. 5G NR can scale to provide coverage for (1) massive Internet of Things (IoT) with ultra-high density (e.g., ~1M nodes / km^2), ultra-low complexity (e.g., ~tens of bits / sec), ultra-low energy (e.g., ~10+ year battery life), and deep coverage with the ability to reach difficult locations; (2) with data security, ultra-high reliability (e.g., ~about 99.9999% reliability), ultra-low latency (e.g., ~about 1 millisecond (ms)), and users with wide range of mobility or lack thereof; and (3) with enhanced mobile broadband including very high capacity (e.g., ~about 10 Tbps / km^2), very high data rates (e.g., multi-Gbps rates, 100+ Mbps user experience rates), and deep awareness with advanced discovery and optimization.

[0023] Devices, networks, and systems may be configured to communicate over one or more portions of the electromagnetic spectrum. The electromagnetic spectrum is often subdivided into various classes, bands, channels, etc., based on frequency or wavelength. In 5G NR, two initial operating bands have been identified with frequency range designations FR1 (410 MHz-7.125 GHz) and FR2 (24.25 GHz-52.6 GHz). Frequencies between FR1 and FR2 are often referred to as mid-band frequencies. Although portions of FR1 are higher than 6 GHz, FR1 is often referred to (interchangeably) as the "sub-6 GHz" band in various documents and papers. Similar nomenclature issues may arise with respect to FR2, which is often referred to (interchangeably) as the "mmWave" band in documents and papers, even though it is distinct from the extremely high frequency (EHF) band (30 GHz-300 GHz) identified by the International Telecommunications Union (ITU) as the "millimeter wave" (mmWave) band.

[0024] With the above aspects in mind, it should be understood that unless otherwise specified, terms such as "sub-6 GHz," as used herein, may broadly refer to frequencies that may be below 6 GHz, may be within FR1, or may include mid-band frequencies. Additionally, it should be understood that unless otherwise specified, terms such as "mmWave," as used herein, may broadly refer to frequencies that may include mid-band frequencies, may be within FR2, or may be within the EHF band.

[0025] 5G NR devices, networks, and systems may be implemented to use optimized OFDM-based waveform features. These features may include advanced wireless technologies such as scalable numerology and transmission time intervals (TTIs), a common flexible framework for efficient multiplexing of services and features in dynamic low-latency time division duplex (TDD) or frequency division duplex (FDD) designs, massive multiple-input multiple-output (MIMO), robust mmWave transmissions, advanced channel coding, and device-centric mobility. The scalability of numerology in 5G NR, along with the scaling of subcarrier spacing, may efficiently address the operation of diverse services across diverse spectrums and diverse deployments. For example, in various outdoor and macro coverage deployments of FDD or TDD implementations below 3 GHz, subcarrier spacing may occur at 15 kHz, for example, across bandwidths of 1, 5, 10, 20 MHz, etc. For various other outdoor and small cell coverage deployments of TDD above 3 GHz, the subcarrier spacing may occur at 30 kHz over an 80 / 100 MHz bandwidth. For various other indoor wideband implementations using TDD in the unlicensed portion of the 5 GHz band, the subcarrier spacing may occur at 60 kHz over a 160 MHz bandwidth. Finally, for various deployments transmitting on a mmWave component at 28 GHz TDD, the subcarrier spacing may occur at 120 kHz over a 500 MHz bandwidth.

[0026] 5G NR's scalable numerology facilitates scalable TTIs for diverse latency and quality of service (QoS) requirements. For example, shorter TTIs may be used for low latency and high reliability, while longer TTIs may be used for higher spectral efficiency. Efficient multiplexing of long and short TTIs allows transmissions to start on symbol boundaries. 5G NR also allows for self-contained, unified subframe designs, with uplink or downlink scheduling information, data, and acknowledgments in the same subframe. Self-contained, unified subframes support communication in unlicensed or contention-based shared spectrum, adaptive uplink or downlink that can be flexibly configured per cell to dynamically switch between uplink and downlink to meet current traffic needs.

[0027] For clarity, some aspects of the apparatus and techniques may be described below with respect to an example 5G NR implementation or in a 5G-centric manner, and 5G terminology may be used as an illustrative example in parts of the following description, however, the description is not intended to be limited to 5G application examples.

[0028] Moreover, it should be understood that in operation, a wireless communications network adapted in accordance with the concepts herein may operate in any combination of licensed or unlicensed spectrum depending on loading and availability. Thus, it will be apparent to those skilled in the art that the systems, apparatus, and methods described herein may be applied to communications systems and applications other than the specific examples shown.

[0029] Although aspects and implementations are described in this application by illustrating some examples, those skilled in the art will understand that additional implementations and use cases may occur in many different configurations and scenarios. The innovations described herein may be implemented across many different platform types, devices, systems, shapes, sizes, packaging arrangements. For example, implementations or applications may occur via integrated chip implementations or other non-modular component-based devices (e.g., end-user devices, vehicles, communication devices, computing devices, industrial equipment, retail or purchasing devices, medical devices, AI-enabled devices, etc.). Some examples may or may not be specifically targeted to a use case or application, but a wide variety of applicability of the described innovations may occur. Implementations may range from chip-level or modular components to non-modular, non-chip-level implementations, and even aggregated, distributed, or original equipment manufacturer (OEM) devices or systems incorporating one or more described aspects. In some practical settings, devices incorporating the described aspects and features may also necessarily include additional components and features in order to implement and practice the claimed and described aspects. It is intended that the innovations described herein may be practiced in a wide variety of implementations, including both large and small devices, chip-level components, multi-component systems (e.g., radio frequency (RF) chains, communication interfaces, processors), distributed configurations, end-user devices, and the like, of various sizes, shapes, and configurations.

[0030] 1 is a block diagram illustrating details of an exemplary wireless communication system according to one or more aspects. The wireless communication system may include a wireless network 100. The wireless network 100 may include, for example, a 5G wireless network. As will be appreciated by those skilled in the art, the components appearing in FIG. 1 may have related counterparts including other network configurations, for example, cellular network configurations and non-cellular network configurations (e.g., device-to-device or peer-to-peer or ad-hoc network configurations, etc.).

[0031] The wireless network 100 shown in FIG. 1 includes several base stations 105 and other network entities. A base station may be a station that communicates with UEs and may also be referred to as an evolved Node B (eNB), next generation eNB (gNB), access point, etc. Each base station 105 may provide communication coverage for a particular geographic area. In 3GPP, the term "cell" may refer to a particular geographic coverage area of ​​a base station or base station subsystem serving the coverage area, depending on the context in which the term is used. In implementations of the wireless network 100 herein, the base stations 105 may be associated with the same operator or different operators (e.g., the wireless network 100 may include a multi-operator wireless network). In addition, in implementations of the wireless network 100 herein, the base station 105 may provide wireless communications using one or more of the same frequencies as adjacent cells (e.g., one or more frequency bands in a licensed spectrum, an unlicensed spectrum, or a combination thereof). In some examples, an individual base station 105 or UE 115 may be operated by more than one network operation entity. In some other examples, each base station 105 and UE 115 may be operated by a single network operating entity.

[0032] A base station may provide communication coverage for a macro cell, or a small cell such as a pico cell or femto cell, or other type of cell. A macro cell generally covers a relatively large geographic area (e.g., a few kilometers in radius) and may allow unrestricted access by UEs with a service subscription with the network provider. A small cell such as a pico cell generally covers a relatively small geographic area and may allow unrestricted access by UEs with a service subscription with the network provider. A small cell such as a femto cell will also generally cover a relatively small geographic area (e.g., a home) and may provide unrestricted access as well as restricted access by UEs with an association with the femto cell (e.g., UEs in a Closed Subscriber Group (CSG), UEs for users in the home, etc.). A base station for a macro cell may be referred to as a macro base station. A base station for a small cell may be referred to as a small cell base station, a pico base station, a femto base station, or a home base station. In the example shown in FIG. 1, base stations 105d and 105e are regular macro base stations, while base stations 105a-105c are macro base stations enabled with one of three-dimensional (3D) MIMO, full dimension (FD) MIMO, or massive MIMO. Base stations 105a-105c take advantage of their higher-dimensional MIMO capabilities to leverage 3D beamforming in both advanced and azimuth beamforming to increase coverage and capacity. Base station 105f is a small cell base station that may be a home node or a portable access point. A base station may support one or multiple (e.g., two, three, four, etc.) cells.

[0033] The wireless network 100 may support synchronous or asynchronous operation. For synchronous operation, the base stations may have similar frame timing and transmissions from different base stations may be approximately aligned in time. For asynchronous operation, the base stations may have different frame timing and transmissions from different base stations may not be aligned in time. In some scenarios, the network may be enabled or configured to handle dynamic switching between synchronous or asynchronous operation.

[0034] The UEs 115 are dispersed throughout the wireless network 100, and each UE may be fixed or mobile. Although mobile devices are generally referred to as UEs in standards and specifications promulgated by 3GPP, it should be appreciated that such devices may additionally or otherwise be referred to by those skilled in the art as mobile stations (MS), subscriber stations, mobile units, subscriber units, wireless units, remote units, mobile devices, wireless devices, wireless communication devices, remote devices, mobile subscriber stations, access terminals (ATs), mobile terminals, wireless terminals, remote terminals, handsets, terminals, user agents, mobile clients, clients, gaming devices, augmented reality devices, vehicle components, vehicle devices, or vehicle modules, or some other suitable terminology. Within this document, a "mobile" device or UE does not necessarily have to be capable of moving and may be stationary. Some non-limiting examples of mobile devices that may have one or more implementations of UE 115 include mobile, cellular (cell) phones, smartphones, Session Initiation Protocol (SIP) phones, Wireless Local Loop (WLL) stations, laptops, personal computers (PCs), notebooks, netbooks, smartbooks, tablets, and personal digital assistants (PDAs).The mobile device may further be an automobile or other transportation vehicle, a satellite radio, a global positioning system (GPS) device, a global navigation satellite system (GNSS) device, a logistics controller, a smart energy or security device, an IoT or "Internet of Everything" (IoE) device such as a solar panel or solar array, city lighting, water, other infrastructure, industrial automation and enterprise devices, eyewear, wearable cameras, smart watches, health or fitness trackers, mammalian implantable devices, gesture tracking devices, medical devices, consumer and wearable devices such as digital audio players (e.g., MP3 players), cameras, game consoles, and digital home or smart home devices such as home audio, video, multimedia devices, appliances, sensors, vending machines, intelligent lighting, home security systems, smart meters, etc. In one aspect, the UE may be a device that includes a Universal Integrated Circuit Card (UICC). In another aspect, the UE may be a device that does not include a UICC. In some aspects, a UE that does not include a UICC may also be referred to as an IoE device. 1 are examples of mobile smartphone type devices accessing the wireless network 100. A UE may also be a machine specifically configured for connected communications, including machine type communications (MTC), enhanced MTC (eMTC), narrowband IoT (NB-IoT), etc. The UEs 115e-115k shown in FIG. 1 are examples of various machines configured for communications accessing the wireless network 100.

[0035] A mobile device such as the UE 115 may be capable of communicating with any type of base station, such as a macro base station, a pico base station, a femto base station, a relay, etc. In FIG. 1, the communication links (represented as lightning bolts) indicate wireless transmissions between the UE and a serving base station, which is a base station designated to serve the UE on the downlink or uplink, or desired transmissions between base stations, as well as backhaul transmissions between base stations. The UE may operate as a base station or other network node in some scenarios. Backhaul communication between base stations of the wireless network 100 may be performed using wired or wireless communication links.

[0036] In operation in the wireless network 100, the base stations 105a-105c serve the UEs 115a and 115b using coordinated spatial techniques such as 3D beamforming and coordinated multipoint (CoMP) or multi-connectivity. The macro base station 105d performs backhaul communications with the base stations 105a-105c and the small cell base station 105f. The macro base station 105d also transmits multicast services to which the UEs 115c and 115d subscribe and receive. Such multicast services may include mobile television or stream video, or other services for providing local community information, such as weather emergencies or alerts such as amber or grey alerts.

[0037] The wireless network 100 of the implementation supports critical communications with ultra-reliable redundant links for critical devices, such as the UE 115e. The redundant communication links with the UE 115e include those from the macro base stations 105d and 105e and the small cell base station 105f. Other machine type devices, such as the UE 115f (thermometer), the UE 115g (smart meter), and the UE 115h (wearable device), may communicate through the wireless network 100 with base stations, such as the small cell base station 105f and the macro base station 105e, directly or by communicating with another user device that relays the information to the network in a multi-hop configuration, such as the UE 115f communicating temperature measurement information to the smart meter UE 115g, which then reports the information to the network through the small cell base station 105f. The wireless network 100 may also provide additional network efficiency through dynamic low-latency TDD or low-latency FDD communications, such as in a vehicle-to-vehicle (V2V) mesh network between the UEs 115i-115k communicating with the macro base station 105e.

[0038] In some aspects of the disclosure, one or more UEs 115 are configured to perform a throughput-based CC tune-away operation. For example, in the example of FIG. 1, UE 115c may be configured to perform a throughput-based baseband (BB) tune-away operation 150. In some examples, use of the throughput-based BB tune-away operation 150 may improve efficiency of resource allocation in a wireless communication system, as described further below.

[0039] FIG. 2 is a block diagram illustrating an example of a base station 105 and a UE 115 according to one or more aspects. The base station 105 and the UE 115 may be any of the base stations and one of the UEs of FIG. 1. In the case of a restricted association scenario (as described above), the base station 105 may be the small cell base station 105f of FIG. 1, the UE 115 may be the UE 115c or 115d operating in the coverage area of ​​the base station 105f, and the UE 115c or 115d will be included in a list of accessible UEs for the small cell base station 105f to access the small cell base station 105f. The base station 105 may also be some other type of base station. As shown in FIG. 2, the base station 105 may be equipped with antennas 234a-234t, and the UE 115 may be equipped with antennas 252a-252r to facilitate wireless communication.

[0040] In the base station 105, the transmit processor 220 may receive data from the data source 212 and control information from a processor 240, such as a processor. The control information may be for a physical broadcast channel (PBCH), a physical control format indicator channel (PCFICH), a physical hybrid-ARQ (automatic repeat request) indicator channel (PHICH), a physical downlink control channel (PDCCH), an enhanced physical downlink control channel (EPDCCH), an MTC physical downlink control channel (MPDCCH), etc. The data may be for a physical downlink shared channel (PDSCH), etc. In addition, the transmit processor 220 may process (e.g., encode and symbol map) the data and control information to obtain data symbols and control symbols, respectively. The transmit processor 220 may also generate reference symbols, for example, for a primary synchronization signal (PSS) and a secondary synchronization signal (SSS), as well as a cell-specific reference signal. The transmit (TX) MIMO processor 230 may perform spatial processing (e.g., precoding) on ​​the data symbols, control symbols, or reference symbols, if applicable, and may provide output symbol streams to modulators (MODs) 232a-t. For example, the spatial processing performed on the data symbols, control symbols, or reference symbols may include precoding. Each modulator 232 may process a respective output symbol stream (e.g., for OFDM, etc.) to obtain an output sample stream. Each modulator 232 may additionally or alternatively process (e.g., convert to analog, amplify, filter, and upconvert) the output sample stream to obtain a downlink signal. The downlink signals from the modulators 232a-t may be transmitted via the antennas 234a-t, respectively.

[0041] At the UE 115, the antennas 252a-252r may receive downlink signals from the base station 105 and may provide received signals to demodulators (DEMODs) 254a-254r, respectively. Each demodulator 254 may condition (e.g., filter, amplify, downconvert, and digitize) a respective received signal to obtain input samples. Each demodulator 254 may further process the input samples (e.g., for OFDM, etc.) to obtain received symbols. A MIMO detector 256 may obtain the received symbols from the demodulators 254a-254r, perform MIMO detection on the received symbols, if applicable, and provide detected symbols. A receive processor 258 may process (e.g., demodulate, deinterleave, and decode) the detected symbols and provide decoded data for the UE 115 to a data sink 260 and provide decoded control information to a processor 280, such as a processor.

[0042] On the uplink, at the UE 115, the transmit processor 264 may receive and process data (e.g., for the Physical Uplink Shared Channel (PUSCH)) from a data source 262 and control information (e.g., for the Physical Uplink Control Channel (PUCCH)) from a processor 280. In addition, the transmit processor 264 may also generate reference symbols for a reference signal. The symbols from the transmit processor 264 may be precoded by a TX MIMO processor 266 if applicable, further processed by modulators 254a-254r (e.g., for SC-FDM, etc.), and transmitted to the base station 105. At the base station 105, uplink signals from the UE 115 may be received by the antennas 234, processed by the demodulator 232, detected by a MIMO detector 236 if applicable, and further processed by the receive processor 238 to obtain decoded data and control information sent by the UE 115. The receive processor 238 may provide the decoded data to a data sink 239 and the decoded control information to a processor 240 .

[0043] The processors 240 and 280 may direct operations in the base station 105 and the UE 115, respectively. The processor 240 or other processors and modules in the base station 105 or the processor 280 or other processors and modules in the UE 115 may perform or direct the execution of various processes for the techniques described herein. For example, the processor 280 may initiate, execute, or control one or more operations described with reference to FIG. 4, one or more operations described with reference to FIG. 5, one or more other operations described herein, or a combination thereof. As an illustrative example, the processor 280 may initiate, execute, or control the throughput-based BB tune-away operation 150. The memory 242 and the memory 282 may store data and program codes for the base station 105 and the UE 115, respectively. The scheduler 244 may schedule the UE for data transmission on the downlink or uplink.

[0044] In some cases, the UE 115 and the base station 105 may operate in a shared radio frequency spectrum band, which may include a licensed frequency spectrum or an unlicensed (e.g., contention-based) frequency spectrum. In the licensed frequency portion of the shared radio frequency spectrum band, the UE 115 or the base station 105 may perform a medium sensing procedure to contend for access to the frequency spectrum, as is conventional. For example, the UE 115 or the base station 105 may perform a listen-before-talk (LBT) or listen-before-transmitting (LBT) procedure, such as a clear channel assessment (CCA), before communicating to determine if a shared channel is available. In some implementations, the CCA may include an energy detection procedure to determine if there are any other active transmissions. For example, the device may infer that a change in a received signal strength indicator (RSSI) of a power meter indicates that the channel is occupied. Specifically, signal power concentrated within some bandwidth and exceeding a predefined noise floor may indicate another wireless transmitter. CCA may also include detection of specific sequences indicative of channel usage. For example, another device may transmit a specific preamble before transmitting a data sequence. In some cases, the LBT procedure may include a wireless node adjusting its own backoff window based on the amount of energy detected on the channel or acknowledgment / negative acknowledgment (ACK / NACK) feedback for its own transmitted packets as a proxy for collisions.

[0045] 3 is a block diagram illustrating an example of a wireless communication system 300 in accordance with one or more aspects. The wireless communication system 300 may include one or more base stations, such as the base station 105. The wireless communication system 300 may further include one or more UEs, such as the UE 115.

[0046] The example of Figure 3 shows that the base station 105 may include one or more processors (such as the processor 240) and may include a memory 242. The base station 105 may further include a transmitter 306 and a receiver 308. The processor 240 may be coupled to the memory 242, the transmitter 306, and the receiver 308. In some examples, the transmitter 306 and the receiver 308 include one or more components described with reference to Figure 2, such as one or more of the modulator / demodulator 232a-t, the MIMO detector 236, the receive processor 238, the transmit processor 220, or the TX MIMO processor 230. In some implementations, the transmitter 306 and the receiver 308 may be integrated into one or more transceivers of the base station 105.

[0047] The transmitter 306 may be configured to transmit reference signals, synchronization signals, control information, and data to one or more other devices, and the receiver 308 may be configured to receive reference signals, control information, and data from one or more other devices. For example, the transmitter 306 may be configured to transmit signaling, control information, and data to the UE 115, and the receiver 308 may be configured to receive signaling, control information, and data from the UE 115.

[0048] 3 also shows that the UE 115 may include one or more processors (such as the processor 280), a memory (such as the memory 282), a transmitter 356, a receiver 358, a first subscriber identity module (SIM) 372, and a second SIM 376. The processor 280 may be coupled to the memory 282, the transmitter 356, the receiver 358, the first SIM 372, and the second SIM 376. In some examples, the transmitter 356 and the receiver 358 may include one or more components described with reference to FIG. 2, such as one or more of the modulator / demodulator 254a-r, the MIMO detector 256, the receive processor 258, the transmit processor 264, or the TX MIMO processor 266. In some implementations, the transmitter 356 and the receiver 358 may be integrated into one or more transceivers of the UE 115.

[0049] The transmitter 356 may be configured to transmit reference signals, synchronization signals, control information, and data to one or more other devices, and the receiver 358 may be configured to receive reference signals, control information, and data from one or more other devices. For example, in some implementations, the transmitter 356 may be configured to transmit signaling, control information, and data to the base station 105, and the receiver 358 may be configured to receive signaling, control information, and data from the base station 105.

[0050] In some implementations, one or more of the transmitter 306, the receiver 308, the transmitter 356, or the receiver 358 may include an antenna array. The antenna array may include multiple antenna elements that perform wireless communication with other devices. In some implementations, the antenna array may perform wireless communication using different beams, also referred to as antenna beams. The beams may include transmit beams and receive beams. To illustrate, the antenna array may include multiple independent sets (or subsets) of antenna elements (or multiple individual antenna arrays), where each set of antenna elements of the antenna array may be configured to communicate using a different respective beam that may have a different respective direction from the other beams. For example, a first set of antenna elements of the antenna array may be configured to communicate via a first beam having a first direction, and a second set of antenna elements of the antenna array may be configured to communicate via a second beam having a second direction. In other implementations, the antenna array may be configured to communicate via more than two beams. In some implementations, one or more sets of antenna elements of the antenna array may be configured to generate multiple beams simultaneously, for example, using multiple RF chains. The set (or subset) of antenna elements may include multiple antenna elements, such as two antenna elements, four antenna elements, ten antenna elements, twenty antenna elements, or any other number of antenna elements greater than two. Although described as an antenna array, in other implementations the antenna array may include or correspond to multiple antenna panels, each of which may be configured to communicate using a different respective beam.

[0051] In some implementations, the wireless communication system 300 operates in accordance with a 5G NR network. For example, the wireless communication system 300 may include a plurality of 5G-capable UEs 115 and a plurality of 5G-capable base stations 105, such as UEs and base stations configured to operate in accordance with a 5G NR network protocol, such as that defined by 3GPP.

[0052] In some implementations, the first SIM 372 is associated with a first subscription 374 and the second SIM 376 is associated with a second subscription 378. For example, the first subscription 374 may be associated with a first RAT of a concurrent radio access technology (RAT) (CRAT) environment supported by the UE 115, and the second subscription 378 may be associated with a second RAT of the CRAT environment. The second RAT may be different from the first RAT. To further illustrate, the first RAT may correspond to one of a 4G LTE wireless communication protocol or a 5G NR wireless communication protocol, and the second RAT may correspond to the other of the 4G LTE wireless communication protocol or the 5G NR wireless communication protocol. In such an example, the first SIM 372 and the second SIM 376 may support use of multiple wireless communication protocols by the UE 115, which may be deployed simultaneously in some cases (e.g., in conjunction with a CRAT environment). To further illustrate, the first RAT may be referred to as a "victim" RAT in the CRAT environment, and the second RAT may be referred to as an "aggressor" RAT in the CRAT environment.

[0053] During operation, the UE 115 may be configured with multiple component carriers (CCs), such as a first CC 322 and a second CC 324. To illustrate, the base station 105 may transmit one or more messages, such as one or more configuration messages 310, that indicate the first CC 322 and the second CC 324. In some implementations, the first CC 322 and the second CC 324 are associated with a first subscription 374.

[0054] The UE 115 may communicate using the first CC 322 and the second CC 324 in association with the first subscription 374. For example, depending on a particular example, the UE 115 may use the first CC 322 and the second CC 324 for downlink communications, uplink communications, sidelink communications, other communications, or a combination thereof. In some examples, the UE 115 may communicate using both the first CC 322 and the second CC 324 for downlink communications, uplink communications, sidelink communications, other communications, or a combination thereof based on a carrier aggregation (CA) technique that combines resources associated with the first CC 322 and the second CC 324 for downlink communications, uplink communications, sidelink communications, other communications, or a combination thereof.

[0055] While communicating using the first CC 322 and the second CC 324 in association with the first subscription 374, the UE 115 may determine a first throughput 342 associated with the first CC 322 and a second throughput 344 associated with the second CC 324. For example, the UE 115 may monitor an amount of data successfully communicated using the first CC 322 during a particular time interval to determine the first throughput 342. As another example, the UE 115 may monitor an amount of data successfully communicated using the second CC 324 during a particular time interval to determine the second throughput 344. In some examples, the UE 115 measures or tracks the amount of data based on decoding statistics, such as PDSCH decoding statistics. In some such examples, the first throughput 342 may correspond to a first value of a PDSCH decoding statistic indicating a first percentage of PDSCH packets received via the first CC 322 that were successfully decoded by the UE 115, and the second throughput 344 may correspond to a second value of a PDSCH decoding statistic indicating a second percentage of PDSCH packets received via the second CC 324 that were successfully decoded by the UE 115.

[0056] Alternatively or additionally, the UE 115 may determine the first throughput 342 and the second throughput 344 based on one or more other parameters associated with the wireless communication system 300. For example, the UE 115 may determine the first throughput 342 and the second throughput 344 based on one or more of scheduling information received from the base station 105, a channel quality indicator (CQI) reported to the base station 105, a block error rate (BLER) measurement, or one or more other parameters, or a combination thereof. In some examples, the one or more parameters include decoding statistics associated with communication using the CC. Illustratively, the first throughput.

[0057] In some implementations, the UE 115 may maintain a throughput database 350. For example, the throughput database 350 may be stored in the memory 282, and the processor 280 may initiate, execute, or control operations associated with the throughput database 350. The throughput database 350 may indicate throughputs associated with CCs (such as a first throughput 342 associated with the first CC 322 and a second throughput 344 associated with the second CC 324) or a ranking of CCs with respect to throughput. To illustrate, after determining the first throughput 342 and the second throughput 344, the processor 280 may store in the throughput database 350 a first instruction 352 of the first CC 322 and a second instruction 354 of the second CC 324.

[0058] In some examples, the processor 280 may sort the first instruction 352 and the second instruction 354 according to one or more metrics, such as the first throughput 342 and the second throughput 344. In an illustrative example, the processor 280 may sort the first instruction 352 and the second instruction 354 according to ascending order of throughput (e.g., from the “worst” throughput to the “best” throughput). As an example, if the processor 280 determines that the second throughput 344 is less than the first throughput 342, the second instruction 354 may occur before the first instruction 352 in the throughput database 350.

[0059] In some circumstances, the UE 115 may detect a resource conflict 346 between the first subscription 374 and the second subscription 378. In some examples, the resource conflict 346 may arise based on one or more operations 362 associated with the second subscription 378. To illustrate, in some circumstances, the first subscription 374 may operate based on a connected mode 382 and the second subscription 378 may operate based on an idle mode 384. The operations based on the connected mode 382 may include transmitting a signal using the transmitter 356, receiving a signal using the receiver 358, or both, and the operations based on the idle mode 384 may include using the receiver 358 to perform the one or more operations 362. In such examples, the resource conflict 346 may arise, such as when the first subscription 374 and the second subscription 378 are scheduled to perform operations simultaneously during a particular time interval.

[0060] In some examples, the UE 115 may detect the resource contention 346 based on scheduling information received from the base station 105, which may indicate that a communication operation of the first subscription 374 is scheduled to occur simultaneously (or within a threshold duration of) one or more operations 362. In some examples, detecting the resource contention 346 includes determining that communicating using both the first CC 322 and the second CC 324 simultaneously (or within a threshold duration of) performing the one or more operations 362 (e.g., based on CA techniques) may be associated with a particular baseband resource usage by the UE 115 that exceeds a baseband resource usage threshold. In some examples, the particular baseband resource usage and baseband resource usage threshold may correspond to or be based on, as illustrative examples, a number of processing cycles of the processor 280, a number of instructions to be executed per second by the processor 280, an amount of data to be stored in the memory 282, or an amount of data to be transferred over a bus of the UE 115.

[0061] To further illustrate, the resource contention 346 may include or correspond to a radio frequency (RF) contention or a baseband contention. In one example of a baseband contention, the first subscription 374 and the second subscription 378 may simultaneously access (or attempt to simultaneously access) one or more baseband components of the UE 115, such as the processor 280, the memory 282, a bus of the UE 115, one or more other components, or a combination thereof. In some circumstances, the baseband contention may result in poor performance or dropped communications, such as when the first SIM 372's access to the processor 280 or memory 282 blocks the second SIM 376 from accessing the processor 280 or memory 282 (or vice versa).

[0062] In some aspects of the disclosure, based on detecting resource contention 346, UE 115 may access throughput database 350 to identify one or more CCs to release in association with throughput-based BB tune-away operation 150. In some examples, UE 115 may release one or more CCs by de-aggregating the one or more CCs from at least one other CC that was combined based on the CA technique (also referred to herein as relinquishing, removing, or sacrificing one or more CCs).

[0063] To further illustrate, the processor 280 may access the throughput database 350 to identify that the first throughput 342 exceeds the second throughput 344 (e.g., based on the second instruction 354 occurring before the first instruction 352 in ascending throughput order). In some such examples, the processor 280 may identify the second CC 324 to be released (e.g., via the throughput-based BB tune away operation 150) to enable the UE 115 to avoid or mitigate the resource contention 346.

[0064] In some other examples, the UE 115 may use one or more other techniques to select an indication of a CC from the throughput database 350. For example, in some situations, each CC indicated by the throughput database 350 may have a common throughput. In such examples, the UE 115 may randomly or pseudo-randomly select the CC to be abandoned. In some other examples, the UE 115 may select the CC with the numerically highest or numerically lowest index value.

[0065] In some examples, the first subscription 374 may avoid communicating based on the second CC 324 during at least the time interval 348, thereby increasing resources available to the second subscription 378 during the time interval 348 (e.g., by “mitigating” the amount of RF or baseband processing associated with the first subscription 374 during the time interval 348). For example, the resources may include RF resources (such as time and frequency resources configured by the base station 105), baseband resources (such as access to the processor 280, memory 282, one or more other components, or a combination thereof), other resources, or a combination thereof. In some examples, the first subscription 374 may, optionally, communicate using the first CC 322 during the time interval 348.

[0066] In some examples, the UE 115 includes a counter, and the UE 115 adjusts a value of the counter during the time interval 348. After initializing the value of the counter (e.g., to 0 or another value) at the start of the time interval 348 and before the value of the counter reaches a threshold corresponding to the end of the time interval 348, the first subscription 374 may avoid communicating using the second CC 324. Based on detecting that the value of the counter meets the threshold, the first subscription 374 may resume (or be eligible to resume) communication using the second CC 324.

[0067] Additionally, during the time interval 348, the second subscription 378 may perform one or more operations 362. The one or more operations 362 may be performed during an idle mode 384 of the second subscription 378 during the time interval 348 and while the first subscription 374 is associated with a connected mode 382.

[0068] In some examples, the UE 115 may perform a tune-away operation (such as the throughput-based BB tune-away operation 150) associated with the first subscription 374. The tune-away operation may include avoiding communications associated with the first subscription 374 using the second CC 324 for at least the time interval 348.

[0069] To illustrate, in some examples, the second CC 324 may be associated with the downlink resource 312. To enable the second subscription 378 to perform one or more operations 362, the UE 115 may transmit one or more of a CQI value 332 or a rank indicator (RI) value 334 to the base station 105 to avoid use of the downlink resource 312 by the base station 105 during the time interval 348. In some examples, the CQI value 332 and the RI value 334 may indicate poor (e.g., “worst case”) channel conditions associated with the downlink resource 312, thereby causing the base station 105 to avoid transmitting a downlink signal using the downlink resource 312. In some other examples, the UE 115 may not indicate that the base station 105 should avoid use of the downlink resource 312 during the time interval 348. For example, in some circumstances, the UE 115 may detect a resource contention 346 just before or just after the start of a downlink transmission from the base station 105. In such cases, the downlink transmission may be associated with one or more dropped communications. In some implementations, the base station 105 may retransmit the one or more dropped communications in conjunction with a Hybrid Automatic Repeat Request (HARQ) scheme, which may include transmission of a negative acknowledgement (NACK) by the UE 115.

[0070] Instead of or in addition to the downlink resources 312, in some examples, the second CC 324 may be associated with the uplink resources 314. The UE 115 may tune the transmitter 356 to avoid use of the uplink resources 314 during the time interval 348.

[0071] In some examples, the one or more operations 362 include at least one control operation that may be performed during an idle mode 384 of the second subscription 378. For example, the one or more operations 362 may include receiving a paging message 336 from a base station, such as the base station 105 or another base station that communicates with the UE 115 in association with the second subscription 378. In some examples, the paging message 336 may prompt the UE 115 to perform a particular operation. For example, the paging message 336 may prompt the UE 115 to transition the second subscription 378 from an idle mode 384 to a connected mode 382 to enable the UE 115 to receive a call associated with the second subscription 378, as an illustrative example.

[0072] Alternatively or additionally, the one or more operations 362 may include receiving a system information block (SIB) message 338 from a base station, such as the base station 105, or another base station that communicates with the UE 115 in connection with the second subscription 378. The SIB message 338 may indicate control information to be used by the UE 115 in connection with the second subscription 378, such as a search space for monitoring paging messages (such as the paging message 336), as an illustrative example.

[0073] Alternatively or additionally, the one or more operations 362 may include performing network measurements 366. For example, the UE 115 may monitor one or more wireless communication channels associated with the second subscription 378 to determine the network measurements 366. In some examples, the UE 115 may report the network measurements 366 to the base station 105 (or another base station), such as by transmitting a measurement report indicating the network measurements 366.

[0074] After performing the one or more operations 362, the UE 115 may detect expiration of the time interval 348. In some examples, based on the expiration of the time interval 348, the UE 115 may reallocate the second CC 324 to the first subscription 374 (e.g., by suspending or terminating the throughput-based BB tune-away operation 150). In some examples, reallocating the second CC 324 to the first subscription 374 includes retuning the transmitter 356 to transmit based on the second CC 324. Alternatively or additionally, reallocating the second CC 324 may include tuning the receiver 358 to receive based on the second CC 324. In an illustrative example, the UE 115 may send one or more of an update to the CQI value 332 or an update to the RI value 334 to indicate that the second CC 324 is no longer associated with poor channel conditions (in which case the base station 105 may resume downlink communications using the second CC 324).

[0075] In some implementations, the UE 115 may periodically or occasionally perform the throughput-based BB tune-away operation 150 based on a periodicity of one or more operations 362. Illustratively, the periodicity may correspond to one or more of a periodicity of paging occasions for monitoring paging messages (such as paging messages 336), a periodicity of SIB messages 338, or a periodicity of network measurements 366.

[0076] Further, in some implementations, the time interval 348 may have a duration based on one or more of the operations 362. By way of example, the time interval 348 may have a duration that corresponds to or is based on one or more of a duration of a paging occasion associated with the paging message 336, a duration of a synchronization signal and physical broadcast channel (SS / PBCH) block measurement timing configuration (SMTC) window associated with the SIB message 338, or a duration associated with performing network measurements 366. To illustrate, the UE 115 may monitor (or be eligible to monitor) the paging message 336 during the paging occasion and may monitor (or be eligible to monitor) the SIB message 338 during the SMTC window.

[0077] By selecting a CC with the lowest throughput for tune-away operation, performance in a wireless communication system may be improved compared to some other techniques. For example, by selecting a “worst” performing CC to relinquish based on recent channel conditions or other metrics, performance degradation for the first subscription 374 may be minimized or reduced compared to a technique that selects resources randomly or according to a LIFO or FIFO basis. As a result, the total throughput associated with the UE 115 may be increased while performance degradation for the victim RAT may be reduced compared to a device that selects resources to be relinquished using another technique, such as by randomly selecting resources or using a LIFO or FIFO technique.

[0078] For ease of explanation, a particular example has been described, but other examples are also within the scope of this disclosure. For example, while two CCs have been described with reference to FIG. 3, in some other examples, the UE 115 may communicate using more than two CCs and may indicate more than two CCs in the throughput database 350. In such examples, the UE 115 may determine and compare throughputs associated with more than two throughputs. As another example, while two SIMs have been described with reference to FIG. 3, in some other examples, the UE further includes more than two SIMs. In such examples, the throughput database 350 may indicate CCs associated with multiple SIMs of the UE 115.

[0079] To further illustrate, in some examples, the UE 115 may release two or more CCs to mitigate or avoid the resource contention 346. As an illustrative example, the resource contention 346 may indicate an amount of resources (such as one or more of RF resources, processing bandwidth, or memory bandwidth) to be used by the second subscription 378 during the one or more operations 362. The UE 115 may select a number (or cardinality) of CCs to be released during the time interval 348 to satisfy the amount of resources to be used by the second subscription 378 during the one or more operations 362. In some instances, the number (or cardinality) of CCs may be greater than one. In such examples, the UE 115 may select two or more CCs with the lowest throughput to be released during the time interval 348.

[0080] 4 is a flow diagram illustrating operations 400 that may be performed by a UE, in accordance with one or more aspects. In some examples, the operations 400 may be performed by the UE 115.

[0081] The operations 400 may include, at 412, populating a database of average throughput per CC for the previous N milliseconds (ms), where N denotes a positive integer. The database may correspond to a throughput database 350, and the average throughput may include a first throughput 342 and a second throughput 344. In some examples, the average throughput is determined based on one or more of scheduling information 402 from a base station, a channel metric 404, or one or more other criteria 406.

[0082] The scheduling information 402 may include a first amount of data scheduled by the base station 105 for the first CC 322 and a second amount of data scheduled by the base station 105 for the second CC 324. In some examples, the channel metric 404 includes a CQI value associated with the first CC 322 and the second CC 324, a BLER measurement associated with the first CC 322 and the second CC 324, an RI value associated with the first CC 322 and the second CC 324, a modulation and coding scheme (MCS) associated with one or more of the first CC 322 and the second CC 324, and one or more other parameters, or a combination thereof. The one or more other criteria 406 may include a power control setting (such as a transmit power level of the transmitter 356 or a receiver power level of the receiver 358), as an illustrative example. For example, if the base station 105 is relatively far from the UE 115, the UE 115 may use a relatively high power control setting. In some cases, communications over relatively long distances may be associated with one or more dropped communications (and loss of throughput), in which case a relatively high power control setting associated with the CC (such as a “maximum” transmit power level of the transmitter 356 or a “maximum” receiver power level of the receiver 358) may indicate that the CC is unreliable.

[0083] The operations 400 may further include, at 414, sorting the CCs based on an average throughput of each CC. For example, sorting the CCs may include sorting the first instruction 354 and the second instruction 352, such as by ordering the second instruction 354 before the first instruction 352 to indicate that the second throughput 344 is less than the first throughput 342, as an illustrative example.

[0084] The operations 400 may further include identifying one or more CCs to be relinquished by the victim RAT to reduce a loss in total throughput while meeting the baseband performance criteria for the aggressor RAT, at 416. For example, the UE 115 may identify, based on the throughput database 350, that relinquishing the second CC 324 instead of the first CC 322 may reduce a loss in total throughput while meeting the baseband performance criteria for the second subscription 378.

[0085] 5 is a flowchart of a method 500 of wireless communication performed by a UE according to some aspects of the present disclosure. In some examples, the method 500 is performed by the UE 115.

[0086] The method 500 includes, at 502, receiving one or more configuration messages indicating a configuration of the UE with a first CC and at least a second CC for a first subscription corresponding to a first SIM of the UE. For example, the UE 115 may receive one or more configuration messages 310 indicating the first CC 322 and the second CC 324 for the first subscription 374 corresponding to the first SIM 372. In some examples, the receiver 358 may be configured to receive the one or more configuration messages 310.

[0087] The method 500 further includes, at 504, performing one or more operations associated with a second subscription corresponding to a second SIM of the UE during the time interval. During the time interval, communication over the first subscription using the second CC is avoided based on a first throughput associated with the first CC exceeding a second throughput associated with the second CC. To illustrate, the UE 115 may perform one or more operations 362 associated with the second subscription 378 during the time interval 348 based on a first throughput 342 associated with the first CC 322 exceeding a second throughput 344 associated with the second CC 324. During the time interval 348, the first subscription 374 may avoid communicating using the second CC 324. In some examples, the first subscription 374 may, optionally, communicate using the first CC 322 during the time interval 348. In some examples, the receiver 358 is configured to perform one or more operations 362, such as by receiving a paging message 336, by receiving a SIB message 338, by performing network measurements 366, or a combination thereof.

As another example, the memory 282 may store resource contention identification instructions 604 executable by the processor 280 to identify a resource contention 346. As an additional example, the memory 282 may store throughput comparison instructions 606 executable by the processor 280 to compare the first throughput 342 and the second throughput 344 to determine whether the first throughput 342 exceeds the second throughput 344.
