Technical Field

[0003] In summary, various aspects of this disclosure relate to wireless communication systems, and more specifically, to wireless communication performed by devices using multiple subscriptions. Background Technology

[0004] Wireless communication systems are widely deployed to provide various types of communication content, such as voice, video, packet data, messaging, and broadcasting. These systems can be multiple access systems capable of supporting communication with multiple users by sharing available system resources (e.g., time, frequency, and power). Examples of such multiple access systems include Code Division Multiple Access (CDMA) systems, Time Division Multiple Access (TDMA) systems, Frequency Division Multiple Access (FDMA) systems, Orthogonal Frequency Division Multiple Access (OFDMA) systems, and Single Carrier Frequency Division Multiple Access (SC-FDMA) systems.

[0005] These multiple access technologies have been adopted in various telecommunications standards to provide a common protocol that enables different wireless devices to communicate at the city, country, region, and even global levels. For example, fifth-generation (5G) wireless communication technology (which may be referred to as 5G New Radio (5G NR)) is envisioned to expand and support a wide variety of use cases and applications related to current generations of mobile networks. In one aspect, 5G communication technologies may include: enhanced mobile broadband addressing human-centric use cases for accessing multimedia content, services, and data; ultra-reliable low-latency communication (URLLC) with specific specifications for latency and reliability; and massive machine-type communication, which allows for a very large number of connected devices and the transmission of relatively small amounts of non-latency-sensitive information.

[0006] In some wireless communication technologies (such as 5G NR), devices, including user equipment (UE), can communicate with one or more cells using multiple subscriptions (e.g., based on multiple subscription identification modules (SIMs) connected to or otherwise available to the UE). A UE can communicate in a dual-subscription dual-standby (DSDS) mode, where the UE can communicate using a first subscription (e.g., a first SIM) (e.g., in a connected state) while simultaneously in standby (e.g., an idle or inactive state) on a second subscription (e.g., a second SIM). A UE can also communicate in a dual-subscription dual-active (DSDA) mode, where the UE can simultaneously transmit and receive using two subscriptions (e.g., two SIMs), meaning both subscriptions can be in a radio resource control (RRC) connected state. Summary of the Invention

[0007] The following is a simplified overview of one or more aspects to provide a basic understanding of these aspects. This overview is not a comprehensive summary of all anticipated aspects, nor is it intended to identify key or important factors of all aspects, nor to describe the scope of any or all aspects. Its sole purpose is to present some concepts of one or more aspects in a simplified form as a prelude to the more detailed descriptions given later.

[0008] According to one aspect, a wireless communication method at a user equipment (UE) is provided, the method comprising: communicating with a plurality of cells in a dual-subscription dual-standby (DSDS) mode based on two separate subscriptions stored at the UE; switching to a dual-subscription dual-activity (DSDA) mode to communicate with the plurality of cells; transmitting auxiliary information to at least one of the plurality of cells, indicating a threshold number of component carriers for the UE, based on the switching to DSDA mode for communication exceeding the number of component carriers allowed for the subscription; and transmitting channel quality indicator (CQI) values ​​for one or more of the plurality of cells to at least one of the plurality of cells, based on the switching to DSDA mode for communication exceeding the number of component carriers allowed for the subscription, to request deactivation of one or more component carriers and one or more cells or release of one or more cells.

[0009] In another example, an apparatus for wireless communication is provided, the apparatus including a transceiver, a memory configured to store instructions, and one or more processors communicatively coupled to the transceiver and the memory. The one or more processors are configured to execute instructions to perform the operations of the methods described herein. In another aspect, an apparatus for wireless communication is provided, the apparatus including units for performing the operations of the methods described herein. In yet another aspect, a computer-readable medium is provided, the computer-readable medium including code executable by one or more processors to perform the operations of the methods described herein.

[0020] Various aspects will now be described with reference to the accompanying drawings. In the following description, numerous specific details are set forth for the purpose of explanation, in order to provide a comprehensive understanding of one or more aspects. However, it will be apparent, however, that such aspects can be implemented without these specific details.

[0021] The described features typically involve modifying the configuration or number of component carriers (CCs) used by a device in wireless communication, which may be referred to as the envelope mode. For example, in wireless communication technologies such as fifth-generation (5G) New Radio (NR), a device such as a User Equipment (UE) can communicate according to a maximum envelope mode, where the envelope mode may correspond to the maximum number of CCs and / or the maximum number of Multiple-Input Multiple-Output (MIMO) layers that the device can use when communicating with other devices or network nodes in the wireless communication network. Furthermore, the device can be configured to communicate using multiple subscriptions, where each subscription can use a different Subscription Identification Module (SIM) within the device. In one example, the device can communicate using dual SIMs, where the SIMs can be internal to the device and / or on a SIM card inserted into a port or interface of the device. In any case, the SIM can include subscription information for the device to use when communicating with one or more wireless networks (e.g., cellular or other wireless communications). The device can be configured to communicate in a Dual Subscription Dual Standby (DSDS) mode, where the device can communicate using a first subscription while remaining in standby mode on a second subscription. The device can also be configured to communicate in a dual subscription dual activity (DSDA) mode, in which the device can use two subscriptions to send and receive communications simultaneously.

[0022] In certain situations, a device can switch between using DSDS and DSDA modes. In DSDA mode, full baseband and radio frequency (RF) resources supporting the maximum number of carriers (e.g., referred to herein as envelope modes) can be considered simultaneously for both subscriptions. In other words, the device splits the envelope mode between the two subscriptions. Splitting the envelope mode in this respect can negatively impact DSDS mode, where the envelope mode is considered on a per-subscription basis to allow a given subscription to use the maximum envelope mode, in cases where DSDA mode is not frequently used. For example, a device can support a total of three downlink (DL) CCs and two uplink (UL) CCs, which can be supported at a given point in time for each of the first subscription (e.g., the default data subscription (DDS)) and the second subscription (e.g., the non-default data subscription (nDDS)). In DSDA mode, the device can allocate resources between the first and second subscriptions (e.g., between DDS and nDDS). For example, for a total of three DL CCs and two UL CCs, the allowed envelope modes could be DDS (two CCs in DL and one CC in UL), nDDS (one CC (for both DL and UL)). However, in DSDS mode, the allowed envelope patterns can be DDS (three DL CCs and two UL CCs) or nDDS (three DL CCs and two UL CCs). In DSDS mode, DDS and nDDS can share resources using tuneaway because at a given point in time, one subscription (e.g., one SIM) is active while another subscription (e.g., one SIM) is in standby mode. For example, for a subscription in standby mode, paging monitoring can be performed under a low duty cycle.

[0023] A radio capability update procedure (with or without Radio Capability Signalling (RACS) optimization) can be used to signal the envelope mode change from DSDS to DSDA to the network. However, the radio capability update procedure may require signaling to both the core network (e.g., via a registration request) and the radio access network (RAN) (e.g., via UECapabilityInformation or a corresponding query). Furthermore, the device may need to release the connection before performing the radio capability update procedure, which may interrupt existing services.

[0024] The aspects described herein relate to an apparatus that modifies the envelope pattern for each subscription based on whether the apparatus is communicating in a multi-subscription active mode (e.g., DSDA) or a multi-subscription standby mode (e.g., DSDS), or when the apparatus switches between DDS and nDDS. For example, when the apparatus is communicating in DSDS and switches to DSDA, the apparatus may reduce the envelope pattern on one or more subscriptions so as not to violate the envelope pattern on all active subscriptions. For example, the apparatus may send auxiliary information to reduce the number of CCs and / or the number of MIMO layers, and / or the apparatus may send a specific channel quality indicator (CQI) value to avoid communication for a subscription in a particular cell. When the apparatus switches from DSDA to DSDS mode, the apparatus may send auxiliary information to increase the number of CCs (e.g., restore deactivated CCs) and / or the number of MIMO layers, and / or the apparatus may send a valid CQI value to induce activation or reconfiguration of deactivated cells.

[0025] Compared to using radio capability update procedures, transmitting auxiliary information and / or CQI to modify the envelope pattern for multiple subscriptions can be more efficient in this regard because it can use less signaling by using only RAN signals, and can reduce complexity in device or network implementations by using existing messages or signaling, etc. This reduction in signaling and device complexity can save baseband or RF resources in the device, which can improve device efficiency, power consumption, avoid service interruptions, and / or improve the user experience in wireless communications using such devices and / or networks.

[0026] The following will refer to Figure 1-8 Provide more detailed descriptions of the features.

[0027] As used herein, the terms “component,” “module,” “system,” etc., are intended to include computer-related entities, such as, but not limited to, hardware, firmware, combinations of hardware and software, software, or software in execution. For example, a component can be, but is not limited to, a process running on a processor, a processor, an object, an executable file, a thread of execution, a program, and / or a computer. For instance, both an application running on a computing device and the computing device itself can be components. One or more components may reside within a process and / or a thread of execution, and components may reside on a single computer and / or be distributed across two or more computers. Furthermore, these components can be executed from various computer-readable media having various data structures stored thereon. Components can communicate, for example, via local and / or remote processes, based on signals having one or more data packets (e.g., data from a component that interacts with a local system, another component in a distributed system, and / or interacts with other systems across a network such as the Internet).

[0028] The technologies described in this article can be used in various wireless communication systems, such as CDMA, TDMA, FDMA, OFDMA, SC-FDMA, and others. The terms "system" and "network" are often used interchangeably. CDMA systems can implement radio technologies such as CDMA2000 and Universal Terrestrial Radio Access (UTRA). CDMA2000 encompasses the IS-2000, IS-95, and IS-856 standards. IS-2000 versions 0 and A are commonly referred to as CDMA2000 1X, 1X, etc. IS-856 (TIA-856) is commonly referred to as CDMA2000 1xEV-DO, High-Speed ​​Packet Data (HRPD), etc. UTRA includes Wideband CDMA (WCDMA) and other variations of CDMA. TDMA systems can implement radio technologies such as the Global System for Mobile Communications (GSM). OFDMA systems can implement technologies such as Ultra Mobile Broadband (UMB), Evolved UTRA (E-UTRA), IEEE 802.11 (Wi-Fi), IEEE 802.16 (WiMAX), IEEE 802.20, and Flash OFDM. TMRadio technologies such as UTRA and E-UTRA are part of the Universal Mobile Telecommunications System (UMTS). 3GPP Long Term Evolution (LTE) and Improved LTE (LTE-A) are newer versions of UMTS using E-UTRA. UTRA, E-UTRA, UMTS, LTE, LTE-A, and GSM are described in documents from an organization called the 3rd Generation Partnership Project (3GPP). CDMA2000 and UMB are described in documents from an organization called the 3rd Generation Partnership Project 2 (3GPP2). The technologies described herein can be used in the systems and radio technologies mentioned above, as well as other systems and radio technologies, including cellular (e.g., LTE) communications on shared radio frequency spectrum bands. However, the description below is for illustrative purposes only regarding LTE / LTE-A systems, and LTE terminology is used in most of the following description, but these technologies can also be applied beyond LTE / LTE-A applications (e.g., to fifth-generation (5G) New Radio (NR) networks or other next-generation communication systems).

[0029] The following description provides examples and does not limit the scope, applicability, or examples set forth in the claims. Changes may be made to the function and arrangement of the elements discussed without departing from the scope of this disclosure. Various processes or components may be appropriately omitted, substituted, or added to the examples. For example, the described methods may be performed in a different order than that described, and various steps may be added, omitted, or combined. Furthermore, features described with respect to some examples may be combined in other examples.

[0030] The aspects or features will be presented in the context of a system comprising multiple devices, components, modules, etc. It should be understood and appreciated that various systems may include additional devices, components, modules, etc., and / or may exclude all of the devices, components, modules, etc., discussed in conjunction with the accompanying drawings. Combinations of these methods may also be used.

[0031] Figure 1This is a diagram illustrating an example of a wireless communication system and access network 100. The wireless communication system (also referred to as a Wireless Wide Area Network (WWAN)) may include base station 102, UE 104, evolved packet core (EPC) 160, and / or 5G core (5GC) 190. Base station 102 may include macro cells (high-power cellular base stations) and / or small cells (low-power cellular base stations). Macro cells may include base stations. Small cells may include femtocells, picocells, and microcells. In one example, base station 102 may also include gNB 180, as further described herein. In one example, according to aspects described herein, some nodes of the wireless communication system may have modem 240 and UE communication component 242 for switching between multiple subscription modes in standby and active states, and accordingly modifying the envelope mode of one or more subscriptions. Although UE 104 is shown as having modem 240 and UE communication component 242, this is an illustrative example, and essentially any node or any type of node may include modem 240 and UE communication component 242 for providing the corresponding functions described herein.

[0032] Base station 102 configured for 4G LTE (which may be collectively referred to as Evolved Universal Mobile Telecommunications System (UMTS) Terrestrial Radio Access Network (E-UTRAN)) can interface with EPC 160 via backhaul link 132 (e.g., using the S1 interface). Base station 102 configured for 5G NR (which may be collectively referred to as Next Generation RAN (NG-RAN)) can interface with 5GC 190 via backhaul link 184. Among other functions, base station 102 can also perform one or more of the following functions: transmission of user data, radio channel encryption and decryption, integrity protection, header compression, mobility control functions (e.g., handover, dual connectivity), inter-cell interference coordination, connection establishment and release, load balancing, distribution of non-access stratum (NAS) messages, NAS node selection, synchronization, radio access network (RAN) sharing, multimedia broadcast multicast service (MBMS), subscriber and device tracking, RAN information management (RIM), paging, location, and delivery of warning messages. Base stations 102 can communicate with each other directly or indirectly (e.g., via EPC 160 or 5GC 190) via backhaul link 134 (e.g., using an X2 interface). Backhaul link 134 can be wired or wireless.

[0033] Base station 102 can wirelessly communicate with one or more UEs 104. Each base station in base station 102 can provide communication coverage for a corresponding geographic coverage area 110. Overlapping geographic coverage areas 110 may exist. For example, small cell 102' may have a coverage area 110' that overlaps with the coverage areas 110 of one or more macro base stations 102. A network that includes both small cells and macro cells can be referred to as a heterogeneous network. The heterogeneous network may also include evolved home node B (eNB) (HeNB), which can provide services to restricted groups (which may be referred to as closed subscriber groups (CSG)). The communication link 120 between base station 102 and UE 104 may include uplink (UL) (also referred to as reverse link) transmission from UE 104 to base station 102 and / or downlink (DL) (also referred to as forward link) transmission from base station 102 to UE 104. The communication link 120 may use multiple-input multiple-output (MIMO) antenna technologies, including spatial multiplexing, beamforming, and / or transmit diversity. The communication link may be via one or more carriers. Base station 102 / UE 104 may use spectrum allocated per carrier up to Y MHz (e.g., 5, 10, 15, 20, 100, 400, etc.) of bandwidth in carrier aggregation for transmissions in the DL and / or UL directions, totaling up to Yx MHz (e.g., for x component carriers). Carriers may be adjacent to each other or may not be adjacent to each other. Carrier allocation may be asymmetric with respect to DL and UL (e.g., more or fewer carriers may be allocated for DL ​​compared to UL). Component carriers may include primary component carriers and one or more secondary component carriers. The primary component carrier may be referred to as the primary cell (PCell), and the secondary component carriers may be referred to as secondary cells (SCells).

[0034] In another example, some UEs 104 may communicate with each other using device-to-device (D2D) communication link 158. D2D communication link 158 may use DL / UL WWAN spectrum. D2D communication link 158 may use one or more sideline channels, such as the Physical Sideline Broadcast Channel (PSBCH), Physical Sideline Discovery Channel (PSDCH), Physical Sideline Shared Channel (PSSCH), and Physical Sideline Control Channel (PSCCH). D2D communication can be achieved through various wireless D2D communication systems, such as FlashLinQ, WiMedia, Bluetooth, ZigBee, Wi-Fi based on the IEEE 802.11 standard, LTE, or NR.

[0035] The wireless communication system may also include a Wi-Fi access point (AP) 150 that communicates with a Wi-Fi station (STA) 152 via a communication link 154 in the 5 GHz unlicensed spectrum. When communicating in the unlicensed spectrum, the STA 152 / AP 150 may perform a free channel assessment (CCA) to determine whether the channel is available before communication.

[0036] Small cell 102' can operate in licensed and / or unlicensed spectrum. When operating in unlicensed spectrum, small cell 102' can employ NR and use the same 5GHz unlicensed spectrum as the Wi-Fi AP 150. Small cell 102' employing NR in unlicensed spectrum can improve coverage of the access network and / or increase the capacity of the access network.

[0037] Base station 102 (whether it is a small cell 102' or a large cell (e.g., a macro base station)) may include an eNB, gNodeB (gNB), or other types of base stations. Some base stations (e.g., gNB 180) may operate in conventional sub-6 GHz spectrum, millimeter wave (mmW) frequencies, and / or near-mmW frequencies to communicate with UE 104. When gNB 180 operates in mmW or near-mmW frequencies, gNB 180 may be referred to as an mmW base station. Extremely high frequency (EHF) is a portion of the electromagnetic spectrum that contains radio frequency (RF). EHF has a range of 30 GHz to 300 GHz and wavelengths between 1 mm and 10 mm. Radio waves in this band may be referred to as millimeter waves. Near-mmW can extend down to frequencies of 3 GHz with wavelengths of 100 mm. Ultra-high frequency (SHF) bands extend between 3 GHz and 30 GHz and are also referred to as centimeter waves. Communication using mmW / near-mmW RF bands has extremely high path loss and short range. mmW base station 180 can utilize beamforming 182 with UE 104 to compensate for extremely high path loss and short range. Base station 102 referred to herein may include gNB 180.

[0038] EPC 160 may include Mobility Management Entity (MME) 162, other MMEs 164, Serving Gateway 166, Multimedia Broadcast Multicast Service (MBMS) Gateway 168, Broadcast Multicast Service Center (BM-SC) 170, and Packet Data Network (PDN) Gateway 172. MME 162 can communicate with Home Subscriber Server (HSS) 174. MME 162 is the control node that handles signaling between UE 104 and EPC 160. Typically, MME 162 provides bearer and connection management. All user Internet Protocol (IP) packets are transmitted through Serving Gateway 166, which is itself connected to PDN Gateway 172. PDN Gateway 172 provides UE IP address allocation and other functions. PDN Gateway 172 and BM-SC 170 are connected to IP Service 176. IP Service 176 may include the Internet, intranet, IP Multimedia Subsystem (IMS), PS streaming service, and / or other IP services. The BM-SC 170 can provide functions for MBMS user service provisioning and delivery. The BM-SC 170 can serve as an entry point for MBMS transmissions to content providers, authorize and initiate MBMS bearer services within a Public Land Mobile Network (PLMN), and schedule MBMS transmissions. The MBMS gateway 168 can be used to allocate MBMS services to base station 102 belonging to a Broadcast-Specific Service Single Frequency Network (MBSFN) area, and can be responsible for session management (start / stop) and collecting eMBMS-related billing information.

[0039] 5GC 190 may include Access and Mobility Management Functions (AMF) 192, other AMFs 193, Session Management Functions (SMF) 194, and User Plane Functions (UPF) 195. AMF 192 may communicate with Unified Data Management (UDM) 196. AMF 192 may be a control node handling signaling between UE 104 and 5GC 190. Typically, AMF 192 can provide QoS streaming and session management. (For example, all user Internet Protocol (IP) packets from one or more UEs 104 can be transmitted via UPF 195. UPF 195 may provide UE IP address allocation and other functions for one or more UEs. UPF 195 connects to IP service 197. IP service 197 may include the Internet, intranet, IP Multimedia Subsystem (IMS), PS streaming service, and / or other IP services.

[0040] A base station may also be referred to as a gNB, Node B, Evolved Node B (eNB), access point, base transceiver, radio base station, radio transceiver, transceiver function, Basic Services Set (BSS), Extended Services Set (ESS), Transmitter Receiver Point (TRP), or some other suitable term. Base station 102 provides UE 104 with access to EPC 160 or 5GC 190. Examples of UE 104 include cellular phones, smartphones, Session Initiation Protocol (SIP) phones, laptops, personal digital assistants (PDAs), satellite radio units, global positioning systems, multimedia devices, video devices, digital audio players (e.g., MP3 players), cameras, game consoles, tablet devices, smart devices, wearable devices, vehicles, electricity meters, gas pumps, large or small kitchen appliances, healthcare devices, implants, sensors / actuators, displays, or any other similarly functional devices. Some UE 104 devices may be referred to as IoT devices (e.g., parking meters, gas pumps, toasters, vehicles, heart monitors, etc.). IoT UEs may include Machine Type Communication (MTC) / Enhanced MTC (eMTC, also known as Category (CAT)-M or Cat M1) UEs, NB-IoT (also known as CAT NB1) UEs, and other types of UEs. In this disclosure, eMTC and NB-IoT may refer to future technologies that may evolve from or be based on these technologies. For example, eMTC may include FeMTC (Further eMTC), eFeMTC (Enhanced Further eMTC), mMTC (Massive MTC), etc., and NB-IoT may include eNB-IoT (Enhanced NB-IoT), FeNB-IoT (Further Enhanced NB-IoT), etc. UE 104 may also be referred to as a station, mobile station, subscriber station, mobile unit, subscriber unit, radio unit, remote unit, mobile device, radio device, wireless communication device, remote device, mobile subscriber station, access terminal, mobile terminal, radio terminal, remote terminal, handheld device, user agent, mobile client, client, or some other suitable term.

[0041] In one example, UE 104 may communicate using multiple subscriptions in a multi-subscription standby mode (e.g., DSDS) or a multi-subscription active mode (e.g., DSDA). Depending on the mode switch, UE communication component 242 may modify the envelope pattern used for one or more subscriptions to ensure that UE 104 does not exceed the maximum envelope pattern. For example, when multiple subscriptions are active simultaneously during a mode switch, UE communication component 242 may reduce the envelope pattern on one or more subscriptions to allow the total envelope pattern used for both subscriptions to not exceed the maximum envelope pattern used for UE 104. In another example, when at least one subscription is in standby (e.g., causing UE 104 to briefly tune away from the active subscription for paging signal monitoring on the standby subscription), when communicating using one (or more) active subscriptions, UE communication component 242 may increase the envelope pattern on one or more subscriptions to maximize the envelope pattern at UE 104.

[0042] Now transferred to Figures 2-8 Each aspect is described with reference to one or more components and one or more methods that can perform the actions or operations described herein, wherein the aspects in dashed form may be optional. Although the following will be in... Figures 3-5 The operations described herein are presented as having a specific order and / or being performed by exemplary components; however, it should be understood that the order of these actions and the components performing these actions may vary depending on the implementation. Furthermore, it should be understood that the actions, functions, and / or components described below may be performed by a specially programmed processor, a processor executing specially programmed software or a computer-readable medium, or any other combination of hardware and / or software components capable of performing the described actions or functions.

[0043] See Figure 2 An example of how UE 104 can be implemented may include a variety of components, some of which have been described above and further described herein, including, for example, one or more processors 212 and memory 216 communicating via one or more buses 244 and transceiver 202, which may operate in conjunction with modem 240 and / or UE communication component 242 to switch between standby and active multi-subscription modes and modify the envelope mode on one or more subscriptions accordingly, based on the aspects described herein.

[0044] In one aspect, one or more processors 212 may include a modem 240 using one or more modem processors and / or may be part of a modem 240. Therefore, various functions relating to the UE communication component 242 may be included in the modem 240 and / or processor 212, and in one aspect may be executed by a single processor, while in other aspects, different functions may be executed by a combination of two or more different processors. For example, in one aspect, one or more processors 212 may include any one or any combination of the following: a modem processor, or a baseband processor, or a digital signal processor, or a transmit processor, or a receiver processor, or a transceiver processor associated with transceiver 202. In other aspects, some features of one or more processors 212 and / or modem 240 associated with the UE communication component 242 may be executed by transceiver 202.

[0045] Furthermore, memory 216 may be configured to store data used herein and / or a local version of application 275 executed by at least one processor 212, or one or more sub-components of UE communication component 242 and / or its sub-components. Memory 216 may include any type of computer-readable medium that can be used by a computer or at least one processor 212, such as random access memory (RAM), read-only memory (ROM), magnetic tape, magnetic disk, optical disk, volatile memory, non-volatile memory, and any combination thereof. For example, in one aspect, when UE 104 is operating at least one processor 212 to execute one or more sub-components of UE communication component 242 and / or its sub-components, memory 216 may be a non-transitory computer-readable storage medium storing one or more computer-executable codes defining one or more sub-components of UE communication component 242 and / or its sub-components and / or associated data.

[0046] Furthermore, memory 216 may include multiple SIMs 278, or may be coupled to or provide multiple SIMs for each of multiple subscriptions. For example, UE 104 may include multiple SIMs 278 as separate SIM cards that can be electronically coupled to UE 104 (e.g., in a SIM card slot), SIMs hard-coded in memory 216 or other parts of UE 104, etc. As described herein, UE 104 may use multiple SIMs 278 for communication using multiple subscriptions (e.g., DSDS or DSDA modes). Thus, for example, UE 104 may use one SIM 278 to communicate with one or more cells via multiple CCs (e.g., as a DDS), and another SIM 278 to communicate with one or more other cells via multiple CCs (e.g., as an nDDS).

[0047] Transceiver 202 may include at least one receiver 206 and at least one transmitter 208. Receiver 206 may include hardware, firmware, and / or processor-executable software code for receiving data, the code including instructions and stored in memory (e.g., a computer-readable medium). For example, receiver 206 may be a radio frequency (RF) receiver. In one aspect, receiver 206 may receive signals transmitted by at least one base station 102. Additionally, receiver 206 may process these received signals and may also obtain measurements of the signals, such as, but not limited to, Ec / Io, signal-to-noise ratio (SNR), reference signal received power (RSRP), received signal strength indicator (RSSI), etc. Transmitter 208 may include hardware, firmware, and / or processor-executable software code for transmitting data, the code including instructions and stored in memory (e.g., a computer-readable medium). Suitable examples of transmitter 208 may include, but are not limited to, RF transmitters.

[0048] Furthermore, in one aspect, UE 104 may include an RF front-end 288 that can communicate with one or more antennas 265 and transceiver 202 to receive and transmit radio transmissions, such as wireless communications transmitted by at least one base station 102 or wireless transmissions transmitted by UE 104. The RF front-end 288 may be connected to one or more antennas 265 and may include one or more low-noise amplifiers (LNAs) 290, one or more switches 292, one or more power amplifiers (PAs) 298, and one or more filters 296 to transmit and receive RF signals.

[0049] In one aspect, the LNA 290 can amplify the received signal at a desired output level. In another aspect, each LNA 290 can have specified minimum and maximum gain values. In yet another aspect, the RF front end 288 can use one or more switches 292 to select a particular LNA 290 and its specified gain value based on the desired gain value for a particular application.

[0050] Furthermore, for example, the RF front-end 288 may use one or more PAs 298 to amplify the signal for RF output at a desired output power level. In one aspect, each PA 298 may have specified minimum and maximum gain values. In another aspect, the RF front-end 288 may use one or more switches 292 to select a particular PA 298 and its specified gain value based on the desired gain value for a particular application.

[0051] Furthermore, for example, the RF front-end 288 may use one or more filters 296 to filter the received signal to obtain the input RF signal. Similarly, in one aspect, for example, a corresponding filter 296 may be used to filter the output from a corresponding PA 298 to produce an output signal for transmission. In one aspect, each filter 296 may be connected to a specific LNA 290 and / or PA 298. In one aspect, the RF front-end 288 may use one or more switches 292 to select a transmit or receive path using specified filters 296, LNA 290, and / or PA 298 based on a configuration specified by transceiver 202 and / or processor 212.

[0052] Thus, transceiver 202 can be configured to transmit and receive wireless signals via RF front-end 288 and one or more antennas 265. In one aspect, the transceiver can be tuned to operate at a specified frequency, enabling UE 104 to communicate with, for example, one or more base stations 102 or one or more cells associated with one or more base stations 102. In another aspect, for example, modem 240 can configure transceiver 202 to operate at a specified frequency and power level based on the UE configuration of UE 104 and the communication protocol used by modem 240.

[0053] In one aspect, modem 240 may be a multi-band, multi-mode modem capable of processing digital data and communicating with transceiver 202, enabling the use of transceiver 202 to transmit and receive digital data. In another aspect, modem 240 may be multi-band and configured to support multiple frequency bands for a specific communication protocol. In another aspect, modem 240 may be multi-mode and configured to support multiple operating networks and communication protocols. In one aspect, modem 240 may control one or more components of UE 104 (e.g., RF front-end 288, transceiver 202) to transmit and / or receive signals from the network based on a specified modem configuration. In one aspect, the modem configuration may be based on the modem's mode and the frequency band in use. In another aspect, the modem configuration may be based on UE configuration information associated with UE 104, such as information provided by the network during cell selection and / or cell reselection.

[0054] In one aspect, according to the aspects described herein, UE communication component 242 may optionally include a subscription mode component 252 for switching between subscription modes to communicate in a wireless network, and / or an envelope mode component 254 for modifying the envelope mode on one or more subscriptions based on the switching.

[0055] In one respect, processor 212 can correspond to the combination Figure 8 The UE describes one or more processors in the processor. Similarly, memory 216 may correspond to the combination of Figure 8 The memory described in the UE.

[0056] Figure 3 A flowchart illustrating an example of a method 300 for modifying a CC or tier configuration based on a switch from a multi-subscription standby mode to a multi-subscription active mode, according to various aspects described herein. In one example, UE 104 can use... Figures 1 to 2 One or more of the components described in the document are used to perform the functions described in method 300.

[0057] In method 300, at block 302, communication with multiple cells in standby mode can be based on multiple subscriptions. In one aspect, subscription mode component 252 (e.g., in conjunction with processor 212, memory 216, transceiver 202, UE communication component 242, etc.) can communicate with multiple cells in standby mode based on multiple subscriptions. For example, subscription mode component 252 can manage subscription modes for communicating with multiple cells on multiple CCs, such as DSDS mode, where UE 104 can use an active subscription (e.g., DDS) to communicate with one or more cells on multiple CCs and periodically tune away to monitor paging signals on standby subscriptions (e.g., nDDS). In one example, subscription mode component 252 can switch between DDS and nDDS for a period of time in different scenarios (e.g., making nDDS an active subscription and DDS a standby subscription), such as when DDS is unavailable, when the communication quality of the cell or CC used for nDDS is at least a threshold better than that of DDS, when UE 104 receives paging signals or other commands for voice or data calls under nDDS, and so on. However, in any case of DSDS mode, UE 104 is communicating using a subscription at a given point in time, for example, one subscription as an active subscription and one or more subscriptions as standby subscriptions, to tune out of the active subscription. Therefore, UE 104 can use maximum envelope mode for each subscription.

[0058] In method 300, at block 304, a handover can be performed to communicate with multiple cells in active mode. In one aspect, subscription mode component 252 (e.g., in conjunction with processor 212, memory 216, transceiver 202, UE communication component 242, etc.) can be switched to communicate with multiple cells in active mode. For example, subscription mode component 252 can be switched to manage subscription modes to communicate with multiple cells simultaneously using multiple subscriptions on multiple CCs, such as in DSDA mode. In some specific examples, subscription mode component 252 can switch to DSDA mode when both subscriptions are to be active, such as when both subscriptions receive or initiate voice or data calls (e.g., in the same or overlapping time periods). In this respect, if UE 104 uses a maximum envelope mode for each subscription (e.g., as configured for DSDS mode), UE 104 may violate the maximum envelope mode by communicating simultaneously. For example, in the case of allocating a maximum envelope mode for the maximum number of CCs (or the maximum number of MIMO layers) for each subscription, UE 104 can use more CCs (or MIMO layers) than the maximum envelope mode when communicating simultaneously on the CCs (or MIMO layers) of two (or more) subscriptions.

[0059] In method 300, at block 306, it can be determined whether (or possibly) the maximum number of CCs, also referred to herein as envelope mode, is exceeded. In one aspect, envelope mode component 254 (e.g., in conjunction with processor 212, memory 216, transceiver 202, UE communication component 242, etc.) can determine whether (or possibly exceeds) the maximum number of CCs for the UE. For example, envelope mode component 254 can determine the total number of CCs (or MIMO layers) used for all active subscriptions and can determine whether that total exceeds the maximum number of CCs. In one example, the maximum number of CCs may be one previously indicated by UE 104 to base station 102 in UE capability information, configured by base station 102 for UE 104, and / or may be based on UE capabilities, UE category, available processing power or other resources at UE 104, etc.

[0060] In method 300, if the maximum number of CCs is exceeded (or may be exceeded) at block 306, auxiliary information indicating a threshold number of CCs can be sent to at least one of the multiple cells at block 308. In one aspect, envelope mode component 254 (e.g., in conjunction with processor 212, memory 216, transceiver 202, UE communication component 242, etc.) can send auxiliary information to at least one of the multiple cells to indicate a threshold number of CCs. In one example, the auxiliary information can indicate a reduction in the maximum number of CCs supported by UE 104 to cause a reduction in the number of CCs on one or more subscriptions, thereby allowing the maximum number of CCs to be met (e.g., not exceeding) when using two subscriptions.

[0061] For example, envelope mode component 254 can send auxiliary information to the primary cell (PCell) of one or more active subscriptions (e.g., DDS, nDDS, or both) in an active subscription. This may cause the PCell to reduce the number of CCs (or MIMO layers) activated for UE 104. In one example, envelope mode component 254 can send auxiliary information in a Radio Resource Control (RRC) UE Auxiliary Information (UAI) as defined in 5G NR. In a particular example, envelope mode component 254 can send an OverheatingAssistance Information Element (IE) with a reducedMaxCC value to cause the PCell to reduce the maximum number of (DL and / or UL) CCs activated for UE 104 in the primary cell group (MCG) and / or secondary cell group (SCG). In another particular example, envelope mode component 254 can send a UEAssistanceInformation IE with a maxCC-Preference value to cause the PCell to reduce the maximum number of CCs activated for UE 104 in the MCG and / or SCG.

[0062] For example, when indicated for addressing overheating, this maximum number of CCs can include the total number of CCs simultaneously supported by both the secondary cell (SCell) for the NR MCG and the primary SCell (PSCell) / SCell for the SCG. This maximum number can include the PSCell / SCell for the SCG under E-UTRA-NR Dual Connectivity (DC) (EN-DC), NG-RAN-E-UTRA-NR DC (NGEN-DC), and NR-E-UTRA DC (NE-DC). When indicated for addressing power saving, this maximum number can include the PSCell / SCell for the cell group associated with the UE auxiliary information. When indicated for addressing power saving, the maximum number of downlink SCells can range up to the currently active configuration.

[0063] In another example, the UE may send auxiliary information as a Channel State Information (CSI) report or in a CSI report, which may include a rank indicator to cause a reduction in rank (e.g., a reduction in the envelope mode associated with the MIMO layer). For example, if the MIMO layer should be reduced from 4 to 2 based on a mode switch, the envelope mode component 254 may send a rank indicator (RI) = 2.

[0064] Furthermore, in method 300, if the maximum number of CCs is exceeded (or may be exceeded) at block 306, at block 310, a CQI value requesting or causing deactivation of one or more CCs and one or more cells, or release of one or more cells, can be sent for one or more cells among the plurality of cells. In one aspect, envelope mode component 254 (e.g., in conjunction with processor 212, memory 216, transceiver 202, UE communication component 242, etc.) can send a CQI value for one or more cells among the plurality of cells to at least one cell among the plurality of cells to request or cause deactivation of one or more CCs and one or more cells, or release of one or more cells. For example, the CQI value may be an out-of-range CQI value, which may not be defined as a valid CQI value (e.g., in wireless communication technologies such as 5G NR). For example, an out-of-range CQI value may be CQI = 0. In any case, the reported CQI value may cause the PCell or network to deactivate one or more CCs, or release one or more corresponding cells on which the UE 104 communicates. In one example, communication component 242 may receive indications of CC deactivation or SCell release from a PCell or other cell associated with an SCell that is being deactivated or released. UE communication component 242 may accordingly avoid communicating with the SCell to conform to a reduced envelope pattern for the relevant subscription. In one example, for each of multiple subscriptions, auxiliary information may be sent at box 308, and / or a CQI value may be sent at box 310 to reduce the envelope pattern (e.g., the number of CCs in use) on both subscriptions.

[0065] In method 300, optionally, at block 312, one or more cells for which CQI values ​​are to be transmitted can be selected from a plurality of cells. In one aspect, envelope mode component 254 (e.g., in conjunction with processor 212, memory 216, transceiver 202, UE communication component 242, etc.) can select one or more cells for which CQI values ​​are to be transmitted from a plurality of cells. For example, envelope mode component 254 can select one or a subset of SCells to transmit CQI=0, and incentivize the network to select the SCell with CQI=0 to release or deactivate the corresponding CC; that is, the network can typically select the SCell with the lowest CQI to release or deactivate the CC upon receiving UAI to reduce CC. In one example, envelope mode component 254 can select any SCell with the minimum bandwidth of the minimum throughput or active bandwidth portion (BWP), any SCell using a specific frequency range (FR) (e.g., FR1 instead of FR2), etc., to maintain the data rate.

[0066] In method 300, optionally, at block 314, it can be determined whether one or more CCs have been deactivated or whether the cell has been released. In one aspect, envelope mode component 254 (e.g., in conjunction with processor 212, memory 216, transceiver 202, UE communication component 242, etc.) can determine whether one or more CCs (e.g., selected CCs and CCs from which CQI values ​​are transmitted) have been deactivated or whether the corresponding cell has been released. If so, at block 316, reporting CQI values ​​for one or more cells can be avoided. In this example, envelope mode component 254 can avoid reporting CQI values ​​for one or more cells because one or more CCs have been deactivated or the cell has been released in other ways. If one or more cells are determined at block 314 to have not yet been deactivated or released, optionally at block 318, a valid or actual CQI can be reported for one or more cells. In this example, envelope mode component 254 can continue to report CQI for one or more cells as usual (e.g., report as actual CQI values).

[0067] Figure 4 The flowchart illustrates an example of a method 400 for modifying a CC or tier configuration based on a switch from a multi-subscription active mode to a multi-subscription standby mode, according to various aspects described herein; in one example, UE 104 can use Figures 1 to 2 One or more of the components described in the document are used to perform the functions described in method 400.

[0068] In method 400, at block 402, communication with multiple cells in active mode can be based on multiple subscriptions. In one aspect, subscription mode component 252 (e.g., in conjunction with processor 212, memory 216, transceiver 202, UE communication component 242, etc.) can communicate with multiple cells in active mode based on multiple subscriptions, as described above. For example, subscription mode component 252 can manage subscription modes to communicate with multiple cells simultaneously on multiple CCs using multiple subscriptions, such as in DSDA mode.

[0069] In method 400, at block 404, a handover can be performed to communicate with multiple cells in standby mode. In one aspect, subscription mode component 252 (e.g., in conjunction with processor 212, memory 216, transceiver 202, UE communication component 242, etc.) can be switched to communicate with multiple cells in standby mode. For example, subscription mode component 252 can be switched to manage subscription modes to communicate with multiple cells using multiple subscriptions on multiple CCs, such as in DSDA mode, where only one (or fewer than all) subscriptions are active at a given point in time.

[0070] In method 400, at block 406, it can be determined whether (or possibly) the maximum number of CCs has been exceeded. In one aspect, envelope mode component 254 (e.g., in conjunction with processor 212, memory 216, transceiver 202, UE communication component 242, etc.) can determine whether (or possibly) the maximum number of CCs has been exceeded (e.g., for a given subscription). For example, envelope mode component 254 can determine the number of CCs (or MIMO layers) for a given subscription and determine whether that number exceeds the maximum number of CCs. For example, the maximum number of CCs could be the maximum number reported in the auxiliary information when UE 104 switches to DSDA mode (e.g., as referenced). Figure 3 Method 300 described in the text).

[0071] In method 400, if the maximum number of CCs is not (or may not) exceeded at block 406, at block 408, auxiliary information indicating a second threshold number of CCs may be sent to at least one of the multiple cells. In one aspect, envelope mode component 254 (e.g., in conjunction with processor 212, memory 216, transceiver 202, UE communication component 242, etc.) may send auxiliary information indicating a second threshold number of CCs to at least one of the multiple cells. In one example, the second threshold number of CCs may be an increase relative to a previously indicated maximum number of CCs (e.g., the maximum number indicated when UE 104 previously entered DSDA mode). For example, envelope mode component 254 may send auxiliary information to a given subscribed PCell. This may cause the PCell to increase the maximum number of CCs (or MIMO layers) activated for UE 104. In one example, envelope mode component 254 may send auxiliary information in a UAI transmitted via RRC as defined in 5G NR. For example, envelope mode component 254 can send UEAssistanceInformation IE with a maxCC-Preference value to enable PCell or allow PCell to increase the maximum number of CCs activated for UE 104 in MCG and / or SCG.

[0072] In another example, the UE may send auxiliary information as a CSI report or send it in a CSI report, which may include a rank indicator to cause an increase in rank (e.g., an increase in envelope mode as associated with the MIMO layer). For example, if the MIMO layer should be increased from 2 to 4 based on a mode switch, the envelope mode component 254 may send a rank indicator (RI) = 4.

[0073] Furthermore, in method 400, if the maximum number of CCs is not exceeded (or may not be exceeded) at block 406, at block 410, a CQI value that requests or causes activation of communication with one or more cells or configuration of one or more cells may be sent for a first portion of one or more cells among a plurality of cells. In one aspect, envelope mode component 254 (e.g., in conjunction with processor 212, memory 216, transceiver 202, UE communication component 242, etc.) may send a CQI value for a first portion of one or more cells to at least one of the plurality of cells to request or cause activation of one or more CCs with a first portion of one or more cells or configuration of a first portion of one or more cells. For example, the CQI value may be an actual CQI value for one or more cells, which may cause the PCell or network to activate (or reactivate) one or more CCs, or configure (or reconfigure) one or more corresponding cells on one or more CCs with which the UE 104 communicates. In one example, for each of the multiple subscriptions, auxiliary information can be sent at box 408, and / or a CQI value can be sent at box 410 to increase the number of CCs on two (or all) subscriptions.

[0074] In method 400, optionally, at block 412, one or more cells for which CQI values ​​are to be transmitted can be selected from a plurality of cells. In one aspect, envelope mode component 254 (e.g., in conjunction with processor 212, memory 216, transceiver 202, UE communication component 242, etc.) can select one or more cells for which CQI values ​​are to be transmitted from a plurality of cells. For example, envelope mode component 254 can select one or a subset of SCells to transmit the actual CQI value to incentivize the network to select a favorable CQI for SCell activation.

[0075] Figure 6An example of a system 600 for modifying the envelope mode for one or more subscriptions based on a multi-subscription mode is shown. System 600 includes a multi-subscription UE (which may be a subscription in the same UE as described) having UE DDS 602 and UE nDDS 604, a gNB 606 associated with the subscription (e.g., DDS), and another gNB 608 associated with another subscription (e.g., nDDS). In system 600, the UE can communicate in DSDS mode. At 610, the UE can enter DSDA, and in call flow 1, at 612, UE DDS 602 can determine whether the envelope mode for DDS has been exceeded (e.g., by joining concurrent communication with nDDS). If so, at 614, UE DDS 602 can send UE assistance information with a reduced maxCC-Preference value to gNB 606, and at 616, can send CQI=0 for one or more SCells, causing gNB 606 to deactivate or release the connection to the SCell to reduce the envelope mode for DSS. Similarly, for example in call flow 2, at 618, UE nDDS 604 can determine whether the envelope mode has been exceeded for nDDS (e.g., by incorporating parallel communication with nDDS). If so, at 620, UE nDDS 604 can send UE assistance information with a reduced maxCC-Preference value to gNB 608, and at 622 can send CQI=0 for one or more SCells, causing gNB 608 to deactivate or release connections to the SCells to reduce the envelope mode used for nDSS.

[0076] After a period of communication in DSDA mode, at 624, the UE can exit DSDA or release a SCell (e.g., and enter DSDS). In this example, in call flow 3, at 626, UE DDS 602 can determine whether the envelope mode has been exceeded for DDS. If not, at 628, UE DDS 602 can send UE assistance information with an increased maxCC-Preference value to gNB 606, and at 630 can send the actual CQI value for one or more SCells, causing gNB 606 to activate the SCell to increase the envelope mode for DDS. Similarly, for example in call flow 4, at 632, UE nDS 604 can determine whether the envelope mode has been exceeded for nDDS. If not, at 634, UE nDDS 604 can send UE assistance information with an increased maxCC-Preference value to gNB 608, and at 636 can send actual CQI values ​​for one or more SCells so that gNB 608 activates SCells to increase the envelope mode for nDDS.

[0077] exist Figure 6 In this example, in call flow 1 or 2, after entering DSDA, if the DDS or nDDS UE has more active SCells than allowed envelope patterns, the DDS or nDDS UE can use UAI to reduce CC and send CQI=0 on SCells exceeding the allowed envelope patterns. In call flow 3 or 4, for example, after exiting DSDA (and entering DSDS) or after a SCell is released and CC reduction is not required, the DDS or nDDS UE can use UAI to restore CC by omitting any preference value and sending CQI with a normal value on the SCell.

[0078] Figure 7An example of timeline 700 for modifying the envelope mode for one or more subscriptions based on a multi-subscription mode is shown. Timeline 700 shows two subscriptions for the UE, including subscription 1 (SUB1) 702 and subscription 2 (SUB2) 704, which can be 5G standalone (5GSA). At 706, SUB1 can be connected under DSDS, and SUB2 704 is in standby (e.g., RRC idle or RRC inactive). In this mode, the envelope mode under DSDS can be three DL CCs and two UL CCs in DDS (SUB1), and three DL CCs and two UL CCs in nDDS (SUB2). At 708, when DDS and nDDS are in an RRC CONNECTED state (e.g., making SUB1 702 connected and SUB2 704 connected), the UE can enter DSDA mode. For each subscription, using the configured envelope mode to make both subscriptions in an RRC CONNECTED state may cause the UE to exceed the maximum envelope mode. Therefore, for SUB1 702, at 710, in the DSDA, the network can be reconfigured or has already been configured with a DDS UE (SUB1 702) having more than two DL SCells or more than one UL SCell. Thus, the UE nDDS can send CQI=0 to reduce to two CCs, and can send a UAI with reducedCCsDL=1 for reducing to two DL CCs and reducedCCsUL=0 for reducing to one UL CC. Similarly, for example, for SUB2 704, at 712, in the DSDA, the network can be reconfigured or has already been configured with a UE nDDS (SUB1 702) with carrier aggregation (CA), or to add CA. Thus, the UE nDDS can send CQI=0 to reduce to one CC, and can send a UAI with reducedCCsDL=0 for reducing to one DL CC and reducedCCsUL=0 for reducing to one UL CC, which can produce the same maximum envelope pattern for five CCs.

[0079] Furthermore, in one example, the UE can switch the DDS to SUB2 704 and the nDDS to SUB1 at 714. In this respect, the UE can similarly modify the envelope mode used for subscription to switch the DDS. For example, for SUB1, if a CA is already configured, the UE nDDS can reduce the envelope mode to one DL CC and one UL CC by sending CQI=0 and UAI (UAI with reducedCCsDL=0 and reducedCCsUL=0 for reducing to one DL CC) on the reduced SCell. Similarly, for SUB2 704, the UE DDS can increase the envelope mode by sending the actual CQI and UAI (UAI with reducedCCsDL=1 and reducedCCsUL=0 for increasing to two DL CCs) for the SCell. See below for further details. Figure 5 This will be described in further detail.

[0080] At 716, the UE can switch back to a DSDS with SUB1 702 as the DDS, which may include releasing the nDDS connection (e.g., with SUB2 704). In this example, the UE can increase the envelope mode of SUB1 702 back to three DL CCs and two UL CCs by sending the actual CQI and UAI for one or more SCells, where the UAI has reducedCCsDL=2 for increasing to three DLCCs (or a null value that may indicate no further preference in the reduction) and reducedCCsUL=1 for increasing to two ULCCs (or a null value that may indicate no further preference in the reduction). In the DSDS, the UE can be inactive on SUB2 704.

[0081] Figure 5 A flowchart illustrating an example of a method 500 for modifying CC or layer configuration based on switching DDS and nDDS, according to various aspects described herein, is shown. In one example, UE 104 can use Figures 1 to 2 One or more of the components described in the document are used to perform the functions described in method 500.

[0082] In method 500, at block 502, a switch between DDS and nDDS can be performed. In one aspect, subscription mode component 252 (e.g., in conjunction with processor 212, memory 216, transceiver 202, UE communication component 242, etc.) can switch between DDS and nDDS. For example, subscription mode component 252 can switch a first subscription, which is DDS, to nDDS, and can switch a second subscription, which is nDDS, to DDS. In one example, with UE 104 in DSDA mode, this may result in the first subscription exceeding the maximum envelope mode (e.g., the maximum number of CCs) for nDDS and / or the second subscription not implementing the maximum envelope mode for DSDS.

[0083] In method 500, at block 504, it can be determined whether (or possibly) the maximum number of CCs has been exceeded for a given subscription. In one aspect, envelope mode component 254 (e.g., in conjunction with processor 212, memory 216, transceiver 202, UE communication component 242, etc.) can determine whether (or possibly) the maximum number of CCs has been exceeded for a given subscription, as described.

[0084] In method 500, at block 504, if a given subscription exceeds (or may exceed) the maximum number of CCs, at block 506, auxiliary information indicating a threshold number of CCs may be sent to at least one of the multiple cells. In one aspect, envelope mode component 254 (e.g., in conjunction with processor 212, memory 216, transceiver 202, UE communication component 242, etc.) may send auxiliary information to at least one of the multiple cells to indicate a threshold number of CCs. As described, for example, the threshold number may be a reduction of a previous amount, resulting in a reduction in the number of CCs used for the subscription. For example, envelope mode component 254 may send auxiliary information to the primary cell (PCell) of the first subscription (e.g., in the case of a first subscription switching from DDS to nDDS), as described.

[0085] Furthermore, in method 500, at block 504, if a given subscription exceeds (or may exceed) the maximum number of CCs, at block 508, for one or more cells among a plurality of cells, a CQI value requesting the deactivation of one or more CCs and one or more cells or the release of one or more cells can be sent.

[0086] In method 500, optionally, at block 510, one or more cells for which CQI values ​​are to be transmitted can be selected from a plurality of cells. In one aspect, envelope mode component 254 (e.g., in conjunction with processor 212, memory 216, transceiver 202, UE communication component 242, etc.) can select one or more cells for which CQI values ​​are to be transmitted from a plurality of cells, as described above.

[0087] In method 500, if at block 504 the maximum number of CCs for a given subscription is not exceeded (or may not be exceeded), auxiliary information indicating a threshold number of CCs can be sent to at least one of the multiple cells at block 512. In one aspect, envelope mode component 254 (e.g., in conjunction with processor 212, memory 216, transceiver 202, UE communication component 242, etc.) can send auxiliary information to at least one of the multiple cells to indicate a threshold number of CCs for the second subscription (e.g., in the case of a second subscription switching from nDDS to DDS), as described. For example, the threshold number could be an increase of a previous amount to result in an increase in the number of CCs used for the subscription.

[0088] Furthermore, in method 500, if at block 504 the maximum number of CCs for a given subscription is not exceeded (or may not exceed), at block 514, a CQI value requesting activation of one or more CCs and one or more cells or configuration of one or more cells can be sent for one or more cells among a plurality of cells. In one aspect, envelope mode component 254 (e.g., in conjunction with processor 212, memory 216, transceiver 202, UE communication component 242, etc.) can send CQI values ​​for one or more cells to at least one cell among a plurality of cells to request activation of one or more CCs and one or more cells of a second subscription or configuration of one or more cells of a second subscription (e.g., in the case of a second subscription switching from nDDS to DDS), as described.

[0089] In method 500, optionally, at block 516, one or more cells for which CQI values ​​are to be transmitted can be selected from a plurality of cells. In one aspect, envelope mode component 254 (e.g., in conjunction with processor 212, memory 216, transceiver 202, UE communication component 242, etc.) can select one or more cells for which CQI values ​​are to be transmitted from a plurality of cells, as described.

[0090] Figure 8 This is a block diagram of a MIMO communication system 800 including base station 102 and UE 104. The MIMO communication system 800 can be shown with reference to... Figure 1The wireless communication access network 100 described herein. Base station 102 may be a reference. Figure 1 Examples of various aspects of the described base station 102 are provided. Base station 102 may be equipped with antennas 834 and 835, and UE 104 may be equipped with antennas 852 and 853. In the MIMO communication system 800, base station 102 can transmit data simultaneously on multiple communication links. Each communication link may be referred to as a "layer," and the "rank" of the communication link may indicate the number of layers used for communication. For example, in a 2x2 MIMO communication system (where base station 102 transmits two "layers"), the rank of the communication link between base station 102 and UE 104 is two.

[0091] At base station 102, transmit (Tx) processor 820 can receive data from a data source. Transmit processor 820 can process the data. Transmit processor 820 can also generate control symbols or reference symbols. Transmit MIMO processor 830 can perform spatial processing (e.g., precoding) on ​​the data symbols, control symbols, or reference symbols (if applicable), and can provide output symbol streams to transmit modulators / demodulators 832 and 833. Each modulator / demodulator 832 to 833 can process the corresponding output symbol stream (e.g., for OFDM, etc.) to obtain an output sample stream. Each modulator / demodulator 832 to 833 can further process (e.g., convert to analog, amplify, filter, and up-convert) the output sample stream to obtain a DL signal. In one example, the DL signal from modulators / demodulators 832 and 833 can be transmitted via antennas 834 and 835, respectively.

[0092] UE 104 can be a reference Figure 1-2 Examples of various aspects of the described UE 104. At UE 104, UE antennas 852 and 853 can receive DL signals from base station 102 and can provide the received signals to modulators / demodulators 854 and 855, respectively. Each modulator / demodulator 854 to 855 can adjust (e.g., filter, amplify, down-convert, and digitize) its respective received signal to obtain an input sample. Each modulator / demodulator 854 to 855 can further process the input sample (e.g., for OFDM, etc.) to obtain received symbols. A MIMO detector 856 can obtain received symbols from modulators / demodulators 854 and 855, perform MIMO detection on the received symbols (if applicable), and provide the detected symbols. A receive (Rx) processor 858 can process (e.g., demodulate, deinterleave, and decode) the detected symbols, provide decoded data for UE 104 to the data output, and provide decoded control information to processor 880 or memory 882.

[0093] In some cases, processor 880 may execute stored instructions to instantiate UE communication component 242 (e.g., see...). Figure 1 and Figure 2 ).

[0094] On the uplink (UL), at UE 104, the transmitting processor 864 can receive and process data from the data source. The transmitting processor 864 can also generate reference symbols for a reference signal. Symbols from the transmitting processor 864 can be pre-encoded (if applicable) by the transmitting MIMO processor 866, further processed by modulators / demodulators 854 and 855 (e.g., for SC-FDMA, etc.), and transmitted to base station 102 according to communication parameters received from base station 102. At base station 102, the UL signal from UE 104 can be received by antennas 834 and 835, processed by modulators / demodulators 832 and 833, detected by MIMO detector 836 (if applicable), and further processed by the receiving processor 838. The receiving processor 838 can provide the decoded data to a data output and to processor 840 or memory 842.

[0095] Components of UE 104 may be implemented individually or collectively using one or more ASICs, which are adapted to perform some or all of the applicable functions in hardware. Each of the mentioned modules may be a unit for performing one or more functions related to the operation of the MIMO communication system 800.
