TECHNIQUES FOR MOBILITY CONTROL FOR DUAL SUBSCRIBER IDENTITY MODULE (SIM) DEVICES
[0001] FIELD OF TECHNOLOGY
[0002] The following relates to wireless communications, including techniques for mobility control for dual Subscriber Identity Module (SIM) devices.BACKGROUND
[0003] Wireless communications systems are widely deployed to provide various types of communication content such as voice, video, packet data, messaging, broadcast, and so on. These systems may be capable of supporting communication with multiple users by sharing the available system resources (e.g., time, frequency, and power) . Examples of such multiple-access systems include fourth generation (4G) systems such as Long Term Evolution (LTE) systems, LTE-Advanced (LTE-A) systems, or LTE-A Pro systems, and fifth generation (5G) systems which may be referred to as New Radio (NR) systems. These systems may employ technologies such as code division multiple access (CDMA) , time division multiple access (TDMA) , frequency division multiple access (FDMA) , orthogonal FDMA (OFDMA) , or discrete Fourier transform spread orthogonal frequency division multiplexing (DFT-S-OFDM) .
[0004] A wireless multiple-access communications system may include one or more base stations, each supporting wireless communication for communication devices, which may be known as user equipment (UE) . Some UEs may include multiple Subscriber Identity Modules (SIMs) , which may allow the UEs to have separate connections to different radio access networks (RANs) , such as with different cellular networks (e.g., two or more 4G, 5G, or 6G networks) or with cellular and Wi-Fi networks, or any combinations thereof. Techniques for more efficient connection management for connections with different RANs may be desirable.SUMMARY
[0005] The described techniques relate to improved methods, systems, devices, and apparatuses that support techniques for mobility control for devices with multiple Subscriber Identity Modules (SIMs) . For example, the described techniques provide for a user equipment (UE) operating in a multi-SIM (MSIM) configuration to estimate a channel capacity for serving and neighboring network devices (e.g., a serving cell and one or more neighboring cells) , and adjust the channel capacity estimation based on a MSIM concurrency loss. A measurement report may be provided to a network device that is adjusted based on the adjusted channel capacity estimation, to allow the network to make mobility decisions that account for MSIM concurrency losses. In some cases, a MSIM concurrency loss may be a performance loss that is estimated for multiple uplink and downlink resource sharing modes. The sharing modes may include a transmit / receive concurrency mode (e.g., whether a transmit / receive chains are shared during concurrent MSIM communications, or a number of receive chains are reduced) , radio frequency (RF) device coexistence (e.g., a transmission on one SIM may interfere with reception at another SIM) , a band in which each MSIM operates (e.g., a neighboring cell of one SIM may operate in a band that has a different concurrency mode than a service cell of another SIM) , or any combinations thereof. Based on the impact on channel capacity, an adjustment to the one or more parameters in a measurement report may be made to reflect the MSIM concurrency preference in mobility control.
[0006] Additionally, or alternatively, a priority associated with each SIM may be used to identify that one SIM (e.g. with lower priority or QoS traffic) should have adjustments made to account for MSIM concurrency loss, and the other SIM (e.g., higher priority SIM) has no adjustments. Further, in some cases, measurement objects for a measurement report may be ordered for measurement scheduling based on concurrency type, bandwidth, priority, or any combinations thereof. Measurement reports may include ranked measurements, or adjusted measurements (e.g., adjusted parameter values) based on the MSIM concurrency loss associated with different measurements.
[0007] A method for wireless communication by a user equipment (UE) is described. The method may include establishing a first connection with a first network device using a first subscriber identity module (SIM) or a Wi-Fi module, establishing a second connection with a second network device using a second SIM, the first connection and the second connection configured for concurrent communications with the first network device and the second network device, respectively, where the first connection and the second connection use a first subset of radio frequency (RF) components at the UE, and transmitting a measurement report that is based on one or more channel measurements of a third network device using the second SIM, where concurrent communications with the third network device and the first network device use the first subset of RF components or a second subset of RF components, and one or more channel measurements of the third network device are adjusted based on an estimated channel capacity of the third network device, and where the estimated channel capacity of the third network device is adjusted based on a concurrency loss associated with the first subset of RF components or the second subset of RF components.
[0008] A UE for wireless communication is described. The UE may include one or more memories storing processor executable code, and one or more processors coupled with the one or more memories. The one or more processors may individually or collectively operable to execute the code to cause the UE to establish a first connection with a first network device using a first SIM or a Wi-Fi module, establish a second connection with a second network device using a second SIM, the first connection and the second connection configured for concurrent communications with the first network device and the second network device, respectively, where the first connection and the second connection use a first subset of RF components at the UE, and transmit a measurement report that is based on one or more channel measurements of a third network device using the second SIM, where concurrent communications with the third network device and the first network device use the first subset of RF components or a second subset of RF components, and one or more channel measurements of the third network device are adjusted based on an estimated channel capacity of the third network device, and where the estimated channel capacity of the third network device is adjusted based on a concurrency loss associated with the first subset of RF components or the second subset of RF components.
[0009] Another UE for wireless communication is described. The UE may include means for establishing a first connection with a first network device using a first SIM or a Wi-Fi module, means for establishing a second connection with a second network device using a second SIM, the first connection and the second connection configured for concurrent communications with the first network device and the second network device, respectively, where the first connection and the second connection use a first subset of RF components at the UE, and means for transmitting a measurement report that is based on one or more channel measurements of a third network device using the second SIM, where concurrent communications with the third network device and the first network device use the first subset of RF components or a second subset of RF components, and one or more channel measurements of the third network device are adjusted based on an estimated channel capacity of the third network device, and where the estimated channel capacity of the third network device is adjusted based on a concurrency loss associated with the first subset of RF components or the second subset of RF components.
[0010] A non-transitory computer-readable medium storing code for wireless communication is described. The code may include instructions executable by a processor to establish a first connection with a first network device using a first SIM or a Wi-Fi module, establish a second connection with a second network device using a second SIM, the first connection and the second connection configured for concurrent communications with the first network device and the second network device, respectively, where the first connection and the second connection use a first subset of RF components at the UE, and transmit a measurement report that is based on one or more channel measurements of a third network device using the second SIM, where concurrent communications with the third network device and the first network device use the first subset of RF components or a second subset of RF components, and one or more channel measurements of the third network device are adjusted based on an estimated channel capacity of the third network device, and where the estimated channel capacity of the third network device is adjusted based on a concurrency loss associated with the first subset of RF components or the second subset of RF components.
[0011] Some examples of the method, UEs, and non-transitory computer-readable medium described herein may further include operations, features, means, or instructions for measuring one or more channel parameters of the third network device, estimating the channel capacity of the third network device based on the one or more channel parameters to generate an estimated channel capacity of the third network device, and adjusting the estimated channel capacity of the third network device based on a type of traffic associated with the second SIM. In some examples of the method, UEs, and non-transitory computer-readable medium described herein, the adjusting the estimated channel capacity may include operations, features, means, or instructions for determining that data traffic associated with the second SIM is data rate sensitive traffic and adjusting the estimated channel capacity of the third network device based on a throughput loss associated with multi-SIM concurrency or SIM-Wi-Fi module concurrency of the first network device and the third network device. In some examples of the method, UEs, and non-transitory computer-readable medium described herein, the adjusting the estimated channel capacity may include operations, features, means, or instructions for determining that data traffic associated with the second SIM is latency sensitive traffic and adjusting the estimated channel capacity of the third network device based on a first concurrency mode and a second concurrency mode, the first concurrency mode associated with concurrent communications using the first network device and the second network device, and the second concurrency mode associated with concurrent communications using the first network device and the third network device.
[0012] In some examples of the method, UEs, and non-transitory computer-readable medium described herein, the first network connection with the first network device may be a Wi-Fi connection, the second network connection with the second network device may be a cellular connection, and the third network device uses the cellular connection.
[0013] Some examples of the method, UEs, and non-transitory computer-readable medium described herein may further include operations, features, means, or instructions for estimating a performance loss associated with multi-SIM concurrency or SIM-Wi-Fi module concurrency at the first network device and the third network device based on an uplink and downlink sharing mode of the first subset of RF components at the UE. In some examples of the method, UEs, and non-transitory computer-readable medium described herein, the uplink and downlink sharing mode includes one or more of a transmit / receive concurrency mode that indicates whether transmit chains use time division duplex or whether a number of available receive chains change during concurrent communications, a RF device coexistence mode that indicates transmissions using the first SIM interfere with concurrent receptions using the second SIM, or a frequency band mode that indicates communications using the second SIM use the second subset of RF components.
[0014] Some examples of the method, UEs, and non-transitory computer-readable medium described herein may further include operations, features, means, or instructions for measuring at least a first reference signal received power (RSRP) of the third network device, estimating the channel capacity of the third network device based on the first RSRP to generate an estimated channel capacity of the third network device, and adjusting a reported value of the first RSRP for transmission in the measurement report, or a ranking of the third network device in the measurement report, based on the estimated channel capacity of the third network device and an estimated channel capacity of the second network device. In some examples of the method, UEs, and non-transitory computer-readable medium described herein, the measurement report may be used for connected mode measurement control, or for idle mode network device selection or reselection.
[0015] Some examples of the method, UEs, and non-transitory computer-readable medium described herein may further include operations, features, means, or instructions for determining that communications using the first SIM or the Wi-Fi module may have a higher priority than communications using the second SIM and adjusting one or more values of the third network device that are provided in the measurement report, and where values of the first network device are unadjusted. In some examples of the method, UEs, and non-transitory computer-readable medium described herein, the priority of communications at the first SIM or the Wi-Fi module and the second SIM may be based on a priority associated with corresponding data traffic, one or more quality of service (QoS) targets associated with corresponding data traffic, or any combinations thereof.
[0016] Some examples of the method, UEs, and non-transitory computer-readable medium described herein may further include operations, features, means, or instructions for scheduling one or more measurements for the third network device and one or more neighboring network devices other than the third network device using the second SIM based on a type of concurrency between the third network device and the one or more other neighboring network devices, a frequency band associated with the third network device and the one or more other neighboring network devices, a number of layers used for communications at the third network device and the one or more other neighboring network devices, or any combinations thereof. In some examples of the method, UEs, and non-transitory computer-readable medium described herein, a metric for ordering a sequence of the one or more measurements may be based on one or more of a network device bandwidth or number of layers, history information associated with the third network device and the one or more neighboring network devices, whether a concurrency type provides independent receive chains and transmit full concurrency, traffic priority, or any combinations thereof.
[0017] Some examples of the method, UEs, and non-transitory computer-readable medium described herein may further include operations, features, means, or instructions for measuring, using the second SIM, one or more channel parameters of the third network device and one or more channel parameters of one or more neighboring network devices other than the third network device, scaling each of the channel parameters, based on a channel capacity estimate of the associated network device and a rank offset of the associated network device, to generate scaled channel parameters, and ranking each of the scaled channel parameters, where the measurement report provides the scaled channel parameters in rank order based on the ranking. In some examples of the method, UEs, and non-transitory computer-readable medium described herein, the rank offset for each network device may be based on a network device bandwidth, a measured signal to interference and noise ratio (SINR) , a concurrency impact to estimated channel capacity of each network device, or any combinations thereof. In some examples of the method, UEs, and non-transitory computer-readable medium described herein, the ranking of each of the scaled channel parameters may be further based on one or more of a traffic type associated with the second SIM, a ratio of uplink to downlink traffic of the first SIM or the Wi-Fi module and the second SIM, latency targets of the of the first SIM or the Wi-Fi module and the second SIM, or any combinations thereof.
[0018] Some examples of the method, UEs, and non-transitory computer-readable medium described herein may further include operations, features, means, or instructions for measuring, using the second SIM, a RSRP of the third network device and one or more neighboring network devices other than the third network device and adjusting the RSRP of the third network device and the one or more neighboring network devices based on a difference between the concurrency loss of the first network device and each of the third network device and the one or more neighboring network devices, and where the adjusted RSRPs may be provided with the measurement report. In some examples of the method, UEs, and non-transitory computer-readable medium described herein, the adjusting the RSRP may be performed for each of the third network device and the one or more neighboring network devices responsive to a corresponding SINR of the measured reference signal being above a threshold SINR value.BRIEF DESCRIPTION OF THE DRAWINGS

[0028] In some wireless communications systems, a user equipment (UE) may include two or more subscriber identification modules (SIMs) , where each SIM is associated with a different network through which the UE may communicate. For example, a first SIM may support communications with a first mobile network operator (MNO) and a second SIM may support communications with a second MNO. In other cases, a first SIM may support communications on a cellular network and a Wi-Fi module (e.g., that performs communications in accordance with IEEE 802.11 protocols) may support communications on a Wi-Fi network. While various examples discussed herein refer to dual SIM or multi-SIM operation, it is to be understood that the described techniques also apply to concurrent communications that use a Wi-Fi module and a SIM. Some UEs may support having each of two or more SIMs active concurrently in accordance with dual-SIM dual-active (DSDA) operation, where a first subscriber and second subscriber (e.g., a first SIM and second SIM, which may also be referred to as a first sub and second sub) in connected mode can share RF resources such as RF components and baseband resources. RF components may include RF front-end devices such as transmit chains, transmit power amplifiers (PAs) , receive chains, antenna switches, antennas, band select switches, receive low noise amplifiers (LNAs) , and the like. Baseband resources may include processing resources (e.g., computational resources) and memory resources that provide computations for maintenance of one or more communication links of the UE, enhancement in quality of the one or more communication links, or any combinations thereof. For example, baseband resources may provide processing resources and memory resources that support a total number of component carriers (CCs) in carrier aggregation in uplink and downlink, a number of multiple-input multiple-output (MIMO) layers, a maximum modulation and coding scheme (MCS) index and modulation scheme, a maximum throughput limit, or any combinations thereof. Such RF front-end devices or components, and baseband resources, may be collectively referred to herein as “resources” or “RF resources” of a UE. Additionally, the RF resources may be shared or separate from “application computational resources” of a UE, which may include resources associated with running a certain application or service associated with a SIM. For example, the application computational resources may include application memory and processing resources (e.g., computation resources, artificial intelligence (AI) resources, machine learning (ML) resources, or any combinations thereof) . Further, while various examples discussed herein relate to cellular wireless communications, the described techniques may be used in any type of system in which RF resources of a UE are shared for communications with two or more separate networks, such as wireless local area networks (WLANs) accessed by a UE via associated access points.
[0029] In some cases, in order to reduce costs, hardware component space, and processing capacity, multiple SIMs may share a same set of RF resources (e.g., baseband resources, RF components) . During multi-SIM (MSIM) operation using shared RF resources, throughput for each served cell may be impacted due to a reduced number of antennas or other RF components that may be used by a SIM, or due to interference generated from the other SIM. However, when making mobility decisions, a network entity relies on measurement reports from UEs, which may not account for MSIM impacts. Thus, in some cases mobility decisions at the network entity may result in a less than optimal cell selection, because a neighboring cell may actually be more beneficial even though one or more parameter measurements (e.g., reference signal received power (RSRP) ) may be lower than a serving cell (e.g., due to the neighboring cell operating in a different band that has lower MSIM impact, or having a larger bandwidth) . Thus, enhancements to MSIM mobility may be beneficial to account for reduced channel capacity of cells in MSIM operation.
[0030] In accordance with various aspects, a UE operating in a MSIM configuration may adjust reported parameters for one or more measurement reports based on impacts due to MSIM operation. In some cases, a UE may estimate a channel capacity for serving and neighboring cells, and adjust the channel capacity estimation based on a MSIM concurrency loss. A measurement report provided to a network entity may be adjusted based on the adjusted channel capacity estimation to allow the network entity to make more accurate mobility decisions that account for MSIM concurrency losses that may be present for one or more cells. In some cases, a performance loss may be estimated for multiple uplink and downlink resource sharing modes. Such sharing modes may include, for example, a transmit / receive concurrency mode (e.g., whether a transmit chain is shared in TDD mode or whether a number of receive chains are reduced) , RF device coexistence (e.g., a transmission on a first SIM may interfere with reception at a second SIM) , a band in which the cell operates (e.g., a neighboring cell of one SIM may operate in a band that has a different concurrency mode) , or any combinations thereof. In some cases, based on the impact on channel capacity, an adjustment to the RSRP or ranking in a measurement report may be made to reflect the MSIM concurrency preference in mobility control. Additionally, or alternatively, a priority associated with each SIM may be used to identify that one SIM (e.g. with lower priority traffic or lower quality of service (QoS) targets) that is selected to have adjustments made to account for MSIM concurrency loss, and the other SIM (e.g., higher priority SIM) has no adjustments. Further, in some aspects, measurement objects for a measurement report may be ordered for measurement scheduling based on concurrency type, bandwidth, priority, or any combinations thereof. In some cases, measurement reports may include ranked measurements, or adjusted measurements (e.g., adjusted RSRP values) based on the MSIM concurrency loss associated with different measurements.
[0031] Various aspects of the subject matter described in this disclosure may be implemented to realize one or more of the following potential advantages. For example, based on implementing the techniques of the present disclosure, the UE may report parameters that are used for mobility determinations to provide efficient communications at the UE. For example, providing adjusted parameters based on MSIM concurrency conditions at the UE may provide that mobility decisions are based on estimated impacts of concurrent MSIM communications (or concurrent Wi-Fi module and SIM communications when the Wi-Fi module and SIM share RF components) . Such techniques may thus enhance UE efficiency, increase data rates, reduce power consumption, and provide for enhanced user experience.
[0032] Aspects of the disclosure are initially described in the context of wireless communications systems. Examples of concurrent MSIM communications, shared RF resources, and measurement scheduling and reporting are then discussed. Aspects of the disclosure are further illustrated by and described with reference to apparatus diagrams, system diagrams, and flowcharts that relate to techniques for mobility control for dual SIM devices.
[0033] FIG. 1 shows an example of a wireless communications system 100 that supports techniques for mobility control for dual SIM devices in accordance with one or more aspects of the present disclosure. The wireless communications system 100 may include one or more network entities 105, one or more UEs 115, and a core network 130. In some examples, the wireless communications system 100 may be a Long Term Evolution (LTE) network, an LTE-Advanced (LTE-A) network, an LTE-A Pro network, a New Radio (NR) network, or a network operating in accordance with other systems and radio technologies, including future systems and radio technologies not explicitly mentioned herein.
[0034] The network entities 105 may be dispersed throughout a geographic area to form the wireless communications system 100 and may include devices in different forms or having different capabilities. In various examples, a network entity 105 may be referred to as a network element, a mobility element, a radio access network (RAN) node, or network equipment, among other nomenclature. In some examples, network entities 105 and UEs 115 may wirelessly communicate via one or more communication links 125 (e.g., a radio frequency (RF) access link) . For example, a network entity 105 may support a coverage area 110 (e.g., a geographic coverage area) over which the UEs 115 and the network entity 105 may establish one or more communication links 125. The coverage area 110 may be an example of a geographic area over which a network entity 105 and a UE 115 may support the communication of signals according to one or more radio access technologies (RATs) .
[0035] The UEs 115 may be dispersed throughout a coverage area 110 of the wireless communications system 100, and each UE 115 may be stationary, or mobile, or both at different times. The UEs 115 may be devices in different forms or having different capabilities. Some example UEs 115 are illustrated in FIG. 1. The UEs 115 described herein may be capable of supporting communications with various types of devices, such as other UEs 115 or network entities 105, as shown in FIG. 1.
[0036] As described herein, a node of the wireless communications system 100, which may be referred to as a network node, or a wireless node, may be a network entity 105 (e.g., any network entity described herein) , a UE 115 (e.g., any UE described herein) , a network controller, an apparatus, a device, a computing system, one or more components, or another suitable processing entity configured to perform any of the techniques described herein. For example, a node may be a UE 115. As another example, a node may be a network entity 105. As another example, a first node may be configured to communicate with a second node or a third node. In one aspect of this example, the first node may be a UE 115, the second node may be a network entity 105, and the third node may be a UE 115. In another aspect of this example, the first node may be a UE 115, the second node may be a network entity 105, and the third node may be a network entity 105. In yet other aspects of this example, the first, second, and third nodes may be different relative to these examples. Similarly, reference to a UE 115, network entity 105, apparatus, device, computing system, or the like may include disclosure of the UE 115, network entity 105, apparatus, device, computing system, or the like being a node. For example, disclosure that a UE 115 is configured to receive information from a network entity 105 also discloses that a first node is configured to receive information from a second node.
[0037] In some examples, network entities 105 may communicate with the core network 130, or with one another, or both. For example, network entities 105 may communicate with the core network 130 via one or more backhaul communication links 120 (e.g., in accordance with an S1, N2, N3, or other interface protocol) . In some examples, network entities 105 may communicate with one another via a backhaul communication link 120 (e.g., in accordance with an X2, Xn, or other interface protocol) either directly (e.g., directly between network entities 105) or indirectly (e.g., via a core network 130) . In some examples, network entities 105 may communicate with one another via a midhaul communication link 162 (e.g., in accordance with a midhaul interface protocol) or a fronthaul communication link 168 (e.g., in accordance with a fronthaul interface protocol) , or any combination thereof. The backhaul communication links 120, midhaul communication links 162, or fronthaul communication links 168 may be or include one or more wired links (e.g., an electrical link, an optical fiber link) , one or more wireless links (e.g., a radio link, a wireless optical link) , among other examples or various combinations thereof. A UE 115 may communicate with the core network 130 via a communication link 155.
[0038] One or more of the network entities 105 described herein may include or may be referred to as a base station 140 (e.g., a base transceiver station, a radio base station, an NR base station, an access point, a radio transceiver, a NodeB, an eNodeB (eNB) , a next-generation NodeB or a giga-NodeB (either of which may be referred to as a gNB) , a 5G NB, a next-generation eNB (ng-eNB) , a Home NodeB, a Home eNodeB, or other suitable terminology) . In some examples, a network entity 105 (e.g., a base station 140) may be implemented in an aggregated (e.g., monolithic, standalone) base station architecture, which may be configured to utilize a protocol stack that is physically or logically integrated within a single network entity 105 (e.g., a single RAN node, such as a base station 140) .
[0039] In some examples, a network entity 105 may be implemented in a disaggregated architecture (e.g., a disaggregated base station architecture, a disaggregated RAN architecture) , which may be configured to utilize a protocol stack that is physically or logically distributed among two or more network entities 105, such as an integrated access backhaul (IAB) network, an open RAN (O-RAN) (e.g., a network configuration sponsored by the O-RAN Alliance) , or a virtualized RAN (vRAN) (e.g., a cloud RAN (C-RAN) ) . For example, a network entity 105 may include one or more of a central unit (CU) 160, a distributed unit (DU) 165, a radio unit (RU) 170, a RAN Intelligent Controller (RIC) 175 (e.g., a Near-Real Time RIC (Near-RT RIC) , a Non-Real Time RIC (Non-RT RIC) ) , a Service Management and Orchestration (SMO) 180 system, or any combination thereof. An RU 170 may also be referred to as a radio head, a smart radio head, a remote radio head (RRH) , a remote radio unit (RRU) , or a transmission reception point (TRP) . One or more components of the network entities 105 in a disaggregated RAN architecture may be co-located, or one or more components of the network entities 105 may be located in distributed locations (e.g., separate physical locations) . In some examples, one or more network entities 105 of a disaggregated RAN architecture may be implemented as virtual units (e.g., a virtual CU (VCU) , a virtual DU (VDU) , a virtual RU (VRU) ) .
[0040] The split of functionality between a CU 160, a DU 165, and an RU 170 is flexible and may support different functionalities depending on which functions (e.g., network layer functions, protocol layer functions, baseband functions, RF functions, and any combinations thereof) are performed at a CU 160, a DU 165, or an RU 170. For example, a functional split of a protocol stack may be employed between a CU 160 and a DU 165 such that the CU 160 may support one or more layers of the protocol stack and the DU 165 may support one or more different layers of the protocol stack. In some examples, the CU 160 may host upper protocol layer (e.g., layer 3 (L3) , layer 2 (L2) ) functionality and signaling (e.g., Radio Resource Control (RRC) , service data adaption protocol (SDAP) , Packet Data Convergence Protocol (PDCP) ) . The CU 160 may be connected to one or more DUs 165 or RUs 170, and the one or more DUs 165 or RUs 170 may host lower protocol layers, such as layer 1 (L1) (e.g., physical (PHY) layer) or L2 (e.g., radio link control (RLC) layer, medium access control (MAC) layer) functionality and signaling, and may each be at least partially controlled by the CU 160. Additionally, or alternatively, a functional split of the protocol stack may be employed between a DU 165 and an RU 170 such that the DU 165 may support one or more layers of the protocol stack and the RU 170 may support one or more different layers of the protocol stack. The DU 165 may support one or multiple different cells (e.g., via one or more RUs 170) . In some cases, a functional split between a CU 160 and a DU 165, or between a DU 165 and an RU 170 may be within a protocol layer (e.g., some functions for a protocol layer may be performed by one of a CU 160, a DU 165, or an RU 170, while other functions of the protocol layer are performed by a different one of the CU 160, the DU 165, or the RU 170) . A CU 160 may be functionally split further into CU control plane (CU-CP) and CU user plane (CU-UP) functions. A CU 160 may be connected to one or more DUs 165 via a midhaul communication link 162 (e.g., F1, F1-c, F1-u) , and a DU 165 may be connected to one or more RUs 170 via a fronthaul communication link 168 (e.g., open fronthaul (FH) interface) . In some examples, a midhaul communication link 162 or a fronthaul communication link 168 may be implemented in accordance with an interface (e.g., a channel) between layers of a protocol stack supported by respective network entities 105 that are in communication via such communication links.
[0041] In wireless communications systems (e.g., wireless communications system 100) , infrastructure and spectral resources for radio access may support wireless backhaul link capabilities to supplement wired backhaul connections, providing an IAB network architecture (e.g., to a core network 130) . In some cases, in an IAB network, one or more network entities 105 (e.g., IAB nodes 104) may be partially controlled by each other. One or more IAB nodes 104 may be referred to as a donor entity or an IAB donor. One or more DUs 165 or one or more RUs 170 may be partially controlled by one or more CUs 160 associated with a donor network entity 105 (e.g., a donor base station 140) . The one or more donor network entities 105 (e.g., IAB donors) may be in communication with one or more additional network entities 105 (e.g., IAB nodes 104) via supported access and backhaul links (e.g., backhaul communication links 120) . IAB nodes 104 may include an IAB mobile termination (IAB-MT) controlled (e.g., scheduled) by DUs 165 of a coupled IAB donor. An IAB-MT may include an independent set of antennas for relay of communications with UEs 115, or may share the same antennas (e.g., of an RU 170) of an IAB node 104 used for access via the DU 165 of the IAB node 104 (e.g., referred to as virtual IAB-MT (vIAB-MT) ) . In some examples, the IAB nodes 104 may include DUs 165 that support communication links with additional entities (e.g., IAB nodes 104, UEs 115) within the relay chain or configuration of the access network (e.g., downstream) . In such cases, one or more components of the disaggregated RAN architecture (e.g., one or more IAB nodes 104 or components of IAB nodes 104) may be configured to operate according to the techniques described herein.
[0042] For instance, an access network (AN) or RAN may include communications between access nodes (e.g., an IAB donor) , IAB nodes 104, and one or more UEs 115. The IAB donor may facilitate connection between the core network 130 and the AN (e.g., via a wired or wireless connection to the core network 130) . That is, an IAB donor may refer to a RAN node with a wired or wireless connection to core network 130. The IAB donor may include a CU 160 and at least one DU 165 (e.g., and RU 170) , in which case the CU 160 may communicate with the core network 130 via an interface (e.g., a backhaul link) . IAB donor and IAB nodes 104 may communicate via an F1 interface according to a protocol that defines signaling messages (e.g., an F1 AP protocol) . Additionally, or alternatively, the CU 160 may communicate with the core network via an interface, which may be an example of a portion of backhaul link, and may communicate with other CUs 160 (e.g., a CU 160 associated with an alternative IAB donor) via an Xn-C interface, which may be an example of a portion of a backhaul link.
[0043] An IAB node 104 may refer to a RAN node that provides IAB functionality (e.g., access for UEs 115, wireless self-backhauling capabilities) . A DU 165 may act as a distributed scheduling node towards child nodes associated with the IAB node 104, and the IAB-MT may act as a scheduled node towards parent nodes associated with the IAB node 104. That is, an IAB donor may be referred to as a parent node in communication with one or more child nodes (e.g., an IAB donor may relay transmissions for UEs through one or more other IAB nodes 104) . Additionally, or alternatively, an IAB node 104 may also be referred to as a parent node or a child node to other IAB nodes 104, depending on the relay chain or configuration of the AN. Therefore, the IAB-MT entity of IAB nodes 104 may provide a Uu interface for a child IAB node 104 to receive signaling from a parent IAB node 104, and the DU interface (e.g., DUs 165) may provide a Uu interface for a parent IAB node 104 to signal to a child IAB node 104 or UE 115.
[0044] For example, IAB node 104 may be referred to as a parent node that supports communications for a child IAB node, or referred to as a child IAB node associated with an IAB donor, or both. The IAB donor may include a CU 160 with a wired or wireless connection (e.g., a backhaul communication link 120) to the core network 130 and may act as parent node to IAB nodes 104. For example, the DU 165 of IAB donor may relay transmissions to UEs 115 through IAB nodes 104, or may directly signal transmissions to a UE 115, or both. The CU 160 of IAB donor may signal communication link establishment via an F1 interface to IAB nodes 104, and the IAB nodes 104 may schedule transmissions (e.g., transmissions to the UEs 115 relayed from the IAB donor) through the DUs 165. That is, data may be relayed to and from IAB nodes 104 via signaling via an NR Uu interface to MT of the IAB node 104. Communications with IAB node 104 may be scheduled by a DU 165 of IAB donor and communications with IAB node 104 may be scheduled by DU 165 of IAB node 104.
[0045] In the case of the techniques described herein applied in the context of a disaggregated RAN architecture, one or more components of the disaggregated RAN architecture may be configured to support techniques for mobility control for dual SIM devices as described herein. For example, some operations described as being performed by a UE 115 or a network entity 105 (e.g., a base station 140) may additionally, or alternatively, be performed by one or more components of the disaggregated RAN architecture (e.g., IAB nodes 104, DUs 165, CUs 160, RUs 170, RIC 175, SMO 180) .
[0046] A UE 115 may include or may be referred to as a mobile device, a wireless device, a remote device, a handheld device, or a subscriber device, or some other suitable terminology, where the “device” may also be referred to as a unit, a station, a terminal, or a client, among other examples. A UE 115 may also include or may be referred to as a personal electronic device such as a cellular phone, a personal digital assistant (PDA) , a tablet computer, a laptop computer, or a personal computer. In some examples, a UE 115 may include or be referred to as a wireless local loop (WLL) station, an Internet of Things (IoT) device, an Internet of Everything (IoE) device, or a machine type communications (MTC) device, among other examples, which may be implemented in various objects such as appliances, or vehicles, meters, among other examples.
[0047] The UEs 115 described herein may be able to communicate with various types of devices, such as other UEs 115 that may sometimes act as relays as well as the network entities 105 and the network equipment including macro eNBs or gNBs, small cell eNBs or gNBs, or relay base stations, among other examples, as shown in FIG. 1.
[0048] The UEs 115 and the network entities 105 may wirelessly communicate with one another via one or more communication links 125 (e.g., an access link) using resources associated with one or more carriers. The term “carrier” may refer to a set of RF spectrum resources having a defined physical layer structure for supporting the communication links 125. For example, a carrier used for a communication link 125 may include a portion of a RF spectrum band (e.g., a bandwidth part (BWP) ) that is operated according to one or more physical layer channels for a given radio access technology (e.g., LTE, LTE-A, LTE-A Pro, NR) . Each physical layer channel may carry acquisition signaling (e.g., synchronization signals, system information) , control signaling that coordinates operation for the carrier, user data, or other signaling. The wireless communications system 100 may support communication with a UE 115 using carrier aggregation or multi-carrier operation. A UE 115 may be configured with multiple downlink component carriers and one or more uplink component carriers according to a carrier aggregation configuration. Carrier aggregation may be used with both frequency division duplexing (FDD) and time division duplexing (TDD) component carriers. Communication between a network entity 105 and other devices may refer to communication between the devices and any portion (e.g., entity, sub-entity) of a network entity 105. For example, the terms “transmitting, ” “receiving, ” or “communicating, ” when referring to a network entity 105, may refer to any portion of a network entity 105 (e.g., a base station 140, a CU 160, a DU 165, a RU 170) of a RAN communicating with another device (e.g., directly or via one or more other network entities 105) .
[0049] In some examples, such as in a carrier aggregation configuration, a carrier may also have acquisition signaling or control signaling that coordinates operations for other carriers. A carrier may be associated with a frequency channel (e.g., an evolved universal mobile telecommunication system terrestrial radio access (E-UTRA) absolute RF channel number (EARFCN) ) and may be identified according to a channel raster for discovery by the UEs 115. A carrier may be operated in a standalone mode, in which case initial acquisition and connection may be conducted by the UEs 115 via the carrier, or the carrier may be operated in a non-standalone mode, in which case a connection is anchored using a different carrier (e.g., of the same or a different radio access technology) .
[0050] The communication links 125 shown in the wireless communications system 100 may include downlink transmissions (e.g., forward link transmissions) from a network entity 105 to a UE 115, uplink transmissions (e.g., return link transmissions) from a UE 115 to a network entity 105, or both, among other configurations of transmissions. Carriers may carry downlink or uplink communications (e.g., in an FDD mode) or may be configured to carry downlink and uplink communications (e.g., in a TDD mode) .
[0051] A carrier may be associated with a particular bandwidth of the RF spectrum and, in some examples, the carrier bandwidth may be referred to as a “system bandwidth” of the carrier or the wireless communications system 100. For example, the carrier bandwidth may be one of a set of bandwidths for carriers of a particular radio access technology (e.g., 1.4, 3, 5, 10, 15, 20, 40, or 80 megahertz (MHz) ) . Devices of the wireless communications system 100 (e.g., the network entities 105, the UEs 115, or both) may have hardware configurations that support communications using a particular carrier bandwidth or may be configurable to support communications using one of a set of carrier bandwidths. In some examples, the wireless communications system 100 may include network entities 105 or UEs 115 that support concurrent communications using carriers associated with multiple carrier bandwidths. In some examples, each served UE 115 may be configured for operating using portions (e.g., a sub-band, a BWP) or all of a carrier bandwidth.
[0052] Signal waveforms transmitted via a carrier may be made up of multiple subcarriers (e.g., using multi-carrier modulation (MCM) techniques such as orthogonal frequency division multiplexing (OFDM) or discrete Fourier transform spread OFDM (DFT-S-OFDM) ) . In a system employing MCM techniques, a resource element may refer to resources of one symbol period (e.g., a duration of one modulation symbol) and one subcarrier, in which case the symbol period and subcarrier spacing may be inversely related. The quantity of bits carried by each resource element may depend on the modulation scheme (e.g., the order of the modulation scheme, the coding rate of the modulation scheme, or both) , such that a relatively higher quantity of resource elements (e.g., in a transmission duration) and a relatively higher order of a modulation scheme may correspond to a relatively higher rate of communication. A wireless communications resource may refer to a combination of an RF spectrum resource, a time resource, and a spatial resource (e.g., a spatial layer, a beam) , and the use of multiple spatial resources may increase the data rate or data integrity for communications with a UE 115.
[0053] One or more numerologies for a carrier may be supported, and a numerology may include a subcarrier spacing (Δf) and a cyclic prefix. A carrier may be divided into one or more BWPs having the same or different numerologies. In some examples, a UE 115 may be configured with multiple BWPs. In some examples, a single BWP for a carrier may be active at a given time and communications for the UE 115 may be restricted to one or more active BWPs.
[0054] The time intervals for the network entities 105 or the UEs 115 may be expressed in multiples of a basic time unit which may, for example, refer to a sampling period of Ts=1 / (Δfmax·Nf) seconds, for which Δfmax may represent a supported subcarrier spacing, and Nf may represent a supported discrete Fourier transform (DFT) size. Time intervals of a communications resource may be organized according to radio frames each having a specified duration (e.g., 10 milliseconds (ms) ) . Each radio frame may be identified by a system frame number (SFN) (e.g., ranging from 0 to 1023) .
[0055] Each frame may include multiple consecutively-numbered subframes or slots, and each subframe or slot may have the same duration. In some examples, a frame may be divided (e.g., in the time domain) into subframes, and each subframe may be further divided into a quantity of slots. Alternatively, each frame may include a variable quantity of slots, and the quantity of slots may depend on subcarrier spacing. Each slot may include a quantity of symbol periods (e.g., depending on the length of the cyclic prefix prepended to each symbol period) . In some wireless communications systems 100, a slot may further be divided into multiple mini-slots associated with one or more symbols. Excluding the cyclic prefix, each symbol period may be associated with one or more (e.g., Nf) sampling periods. The duration of a symbol period may depend on the subcarrier spacing or frequency band of operation.
[0056] A subframe, a slot, a mini-slot, or a symbol may be the smallest scheduling unit (e.g., in the time domain) of the wireless communications system 100 and may be referred to as a transmission time interval (TTI) . In some examples, the TTI duration (e.g., a quantity of symbol periods in a TTI) may be variable. Additionally, or alternatively, the smallest scheduling unit of the wireless communications system 100 may be dynamically selected (e.g., in bursts of shortened TTIs (sTTIs) ) .
[0057] Physical channels may be multiplexed for communication using a carrier according to various techniques. A physical control channel and a physical data channel may be multiplexed for signaling via a downlink carrier, for example, using one or more of time division multiplexing (TDM) techniques, frequency division multiplexing (FDM) techniques, or hybrid TDM-FDM techniques. A control region (e.g., a control resource set (CORESET) ) for a physical control channel may be defined by a set of symbol periods and may extend across the system bandwidth or a subset of the system bandwidth of the carrier. One or more control regions (e.g., CORESETs) may be configured for a set of the UEs 115. For example, one or more of the UEs 115 may monitor or search control regions for control information according to one or more search space sets, and each search space set may include one or multiple control channel candidates in one or more aggregation levels arranged in a cascaded manner. An aggregation level for a control channel candidate may refer to an amount of control channel resources (e.g., control channel elements (CCEs) ) associated with encoded information for a control information format having a given payload size. Search space sets may include common search space sets configured for sending control information to multiple UEs 115 and UE-specific search space sets for sending control information to a specific UE 115.
[0058] A network entity 105 may provide communication coverage via one or more cells, for example a macro cell, a small cell, a hot spot, or other types of cells, or any combination thereof. The term “cell” may refer to a logical communication entity used for communication with a network entity 105 (e.g., using a carrier) and may be associated with an identifier for distinguishing neighboring cells (e.g., a physical cell identifier (PCID) , a virtual cell identifier (VCID) , or others) . In some examples, a cell also may refer to a coverage area 110 or a portion of a coverage area 110 (e.g., a sector) over which the logical communication entity operates. Such cells may range from smaller areas (e.g., a structure, a subset of structure) to larger areas depending on various factors such as the capabilities of the network entity 105. For example, a cell may be or include a building, a subset of a building, or exterior spaces between or overlapping with coverage areas 110, among other examples.
[0059] In some examples, a network entity 105 (e.g., a base station 140, an RU 170) may be movable and therefore provide communication coverage for a moving coverage area 110. In some examples, different coverage areas 110 associated with different technologies may overlap, but the different coverage areas 110 may be supported by the same network entity 105. In some other examples, the overlapping coverage areas 110 associated with different technologies may be supported by different network entities 105. The wireless communications system 100 may include, for example, a heterogeneous network in which different types of the network entities 105 provide coverage for various coverage areas 110 using the same or different radio access technologies.
[0060] The wireless communications system 100 may be configured to support ultra-reliable communications or low-latency communications, or various combinations thereof. For example, the wireless communications system 100 may be configured to support ultra-reliable low-latency communications (URLLC) . The UEs 115 may be designed to support ultra-reliable, low-latency, or critical functions. Ultra-reliable communications may include private communication or group communication and may be supported by one or more services such as push-to-talk, video, or data. Support for ultra-reliable, low-latency functions may include prioritization of services, and such services may be used for public safety or general commercial applications. The terms ultra-reliable, low-latency, and ultra-reliable low-latency may be used interchangeably herein.
[0061] In some examples, a UE 115 may be configured to support communicating directly with other UEs 115 via a device-to-device (D2D) communication link 135 (e.g., in accordance with a peer-to-peer (P2P) , D2D, or sidelink protocol) . In some examples, one or more UEs 115 of a group that are performing D2D communications may be within the coverage area 110 of a network entity 105 (e.g., a base station 140, an RU 170) , which may support aspects of such D2D communications being configured by (e.g., scheduled by) the network entity 105. In some examples, one or more UEs 115 of such a group may be outside the coverage area 110 of a network entity 105 or may be otherwise unable to or not configured to receive transmissions from a network entity 105. In some examples, groups of the UEs 115 communicating via D2D communications may support a one-to-many (1: M) system in which each UE 115 transmits to each of the other UEs 115 in the group. In some examples, a network entity 105 may facilitate the scheduling of resources for D2D communications. In some other examples, D2D communications may be carried out between the UEs 115 without an involvement of a network entity 105.
[0062] The core network 130 may provide user authentication, access authorization, tracking, Internet Protocol (IP) connectivity, and other access, routing, or mobility functions. The core network 130 may be an evolved packet core (EPC) or 5G core (5GC) , which may include at least one control plane entity that manages access and mobility (e.g., a mobility management entity (MME) , an access and mobility management function (AMF) ) and at least one user plane entity that routes packets or interconnects to external networks (e.g., a serving gateway (S-GW) , a Packet Data Network (PDN) gateway (P-GW) , or a user plane function (UPF) ) . The control plane entity may manage non-access stratum (NAS) functions such as mobility, authentication, and bearer management for the UEs 115 served by the network entities 105 (e.g., base stations 140) associated with the core network 130. User IP packets may be transferred through the user plane entity, which may provide IP address allocation as well as other functions. The user plane entity may be connected to IP services 150 for one or more network operators. The IP services 150 may include access to the Internet, Intranet (s) , an IP Multimedia Subsystem (IMS) , or a Packet-Switched Streaming Service.
[0063] The wireless communications system 100 may operate using one or more frequency bands, which may be in the range of 300 megahertz (MHz) to 300 gigahertz (GHz) . Generally, the region from 300 MHz to 3 GHz is known as the ultra-high frequency (UHF) region or decimeter band because the wavelengths range from approximately one decimeter to one meter in length. UHF waves may be blocked or redirected by buildings and environmental features, which may be referred to as clusters, but the waves may penetrate structures sufficiently for a macro cell to provide service to the UEs 115 located indoors. Communications using UHF waves may be associated with smaller antennas and shorter ranges (e.g., less than 100 kilometers) compared to communications using the smaller frequencies and longer waves of the high frequency (HF) or very high frequency (VHF) portion of the spectrum below 300 MHz.
[0064] The wireless communications system 100 may utilize both licensed and unlicensed RF spectrum bands. For example, the wireless communications system 100 may employ License Assisted Access (LAA) , LTE-Unlicensed (LTE-U) radio access technology, or NR technology using an unlicensed band such as the 5 GHz industrial, scientific, and medical (ISM) band. While operating using unlicensed RF spectrum bands, devices such as the network entities 105 and the UEs 115 may employ carrier sensing for collision detection and avoidance. In some examples, operations using unlicensed bands may be based on a carrier aggregation configuration in conjunction with component carriers operating using a licensed band (e.g., LAA) . Operations using unlicensed spectrum may include downlink transmissions, uplink transmissions, P2P transmissions, or D2D transmissions, among other examples.
[0065] A network entity 105 (e.g., a base station 140, an RU 170) or a UE 115 may be equipped with multiple antennas, which may be used to employ techniques such as transmit diversity, receive diversity, multiple-input multiple-output (MIMO) communications, or beamforming. The antennas of a network entity 105 or a UE 115 may be located within one or more antenna arrays or antenna panels, which may support MIMO operations or transmit or receive beamforming. For example, one or more base station antennas or antenna arrays may be co-located at an antenna assembly, such as an antenna tower. In some examples, antennas or antenna arrays associated with a network entity 105 may be located at diverse geographic locations. A network entity 105 may include an antenna array with a set of rows and columns of antenna ports that the network entity 105 may use to support beamforming of communications with a UE 115. Likewise, a UE 115 may include one or more antenna arrays that may support various MIMO or beamforming operations. Additionally, or alternatively, an antenna panel may support RF beamforming for a signal transmitted via an antenna port.
[0066] The network entities 105 or the UEs 115 may use MIMO communications to exploit multipath signal propagation and increase spectral efficiency by transmitting or receiving multiple signals via different spatial layers. Such techniques may be referred to as spatial multiplexing. The multiple signals may, for example, be transmitted by the transmitting device via different antennas or different combinations of antennas. Likewise, the multiple signals may be received by the receiving device via different antennas or different combinations of antennas. Each of the multiple signals may be referred to as a separate spatial stream and may carry information associated with the same data stream (e.g., the same codeword) or different data streams (e.g., different codewords) . Different spatial layers may be associated with different antenna ports used for channel measurement and reporting. MIMO techniques include single-user MIMO (SU-MIMO) , for which multiple spatial layers are transmitted to the same receiving device, and multiple-user MIMO (MU-MIMO) , for which multiple spatial layers are transmitted to multiple devices.
[0067] Beamforming, which may also be referred to as spatial filtering, directional transmission, or directional reception, is a signal processing technique that may be used at a transmitting device or a receiving device (e.g., a network entity 105, a UE 115) to shape or steer an antenna beam (e.g., a transmit beam, a receive beam) along a spatial path between the transmitting device and the receiving device. Beamforming may be achieved by combining the signals communicated via antenna elements of an antenna array such that some signals propagating along particular orientations with respect to an antenna array experience constructive interference while others experience destructive interference. The adjustment of signals communicated via the antenna elements may include a transmitting device or a receiving device applying amplitude offsets, phase offsets, or both to signals carried via the antenna elements associated with the device. The adjustments associated with each of the antenna elements may be defined by a beamforming weight set associated with a particular orientation (e.g., with respect to the antenna array of the transmitting device or receiving device, or with respect to some other orientation) .
[0068] The wireless communications system 100 may be a packet-based network that operates according to a layered protocol stack. In the user plane, communications at the bearer or PDCP layer may be IP-based. An RLC layer may perform packet segmentation and reassembly to communicate via logical channels. A MAC layer may perform priority handling and multiplexing of logical channels into transport channels. The MAC layer also may implement error detection techniques, error correction techniques, or both to support retransmissions to improve link efficiency. In the control plane, an RRC layer may provide establishment, configuration, and maintenance of an RRC connection between a UE 115 and a network entity 105 or a core network 130 supporting radio bearers for user plane data. A PHY layer may map transport channels to physical channels.
[0069] In some aspects, one or more UEs 115 may operate according to a MSIM configuration, and may adjust reported parameters for one or more measurement reports based on impacts due to MSIM operation. In some cases, a UE may estimate a channel capacity for serving and neighboring cells, and adjust the channel capacity estimation based on a MSIM concurrency loss. In some cases, a performance loss may be estimated for multiple uplink and downlink resource sharing modes, such as a transmit / receive concurrency mode, RF device coexistence, a band in which the cell operates, or any combinations thereof. In some cases, based on the impact on channel capacity, an adjustment to the RSRP or ranking in a measurement report may be made to reflect the MSIM concurrency preference in mobility control. Additionally, or alternatively, a priority associated with each SIM may be used to select one SIM to have adjustments that account for MSIM concurrency loss, and the other SIM (e.g., higher priority SIM) has no adjustments. Further, in some aspects, measurement objects for a measurement report may be ordered for measurement scheduling based on concurrency type, bandwidth, priority, or any combinations thereof. In some cases, measurement reports may include ranked measurements, or adjusted measurements (e.g., adjusted RSRP values) based on the MSIM concurrency loss associated with different measurements.
[0070] FIG. 2 shows an example of a wireless communications system 200 that supports techniques for mobility control for dual SIM devices in accordance with one or more aspects of the present disclosure. In some examples, wireless communications system 200 may implement aspects of wireless communications system 100. In the example of FIG. 2, wireless communications system 200 may include first network entity 105-a, a second network entity 105-b, a third network entity 105-c, and UE 115-a, which may be examples of the corresponding devices described with respect to FIG. 1. The first network entity 105-a may provide communications for a first network associated with a first SIM 235 at the UE 115-a, and the second network entity 105-b may provide communications for a second network associated with a second SIM 240 at the UE 115-a. The first network entity 105-a may transmit downlink communications 205 to the UE 115-a, and the UE 115-a may transmit uplink communications 210 to the first network entity 105-a, where the downlink communications 205 and uplink communications 210 are associated with the first SIM 235. Likewise, the network entity 105-b may transmit downlink communications 215 to the UE 115-a, and the UE 115-amay transmit uplink communications 220 to the second network entity 105-b, where the downlink communications 215 and uplink communications 220 are associated with the second SIM 240.
[0071] To support communications between first network entity 105-a, second network entity 105-b, and UE 115-a, each network entity 105 may transmit one or more reference signals 250 (e.g., channel state information (CSI) reference signals, synchronization signal blocks (SSBs) , demodulation reference signals (DMRSs) , tracking reference signals (TRSs) , and the like) . The UE 115-a may measure one or more metrics of received reference signals 250 and provide measurement reports 255 to the network entity 105. The UE 115-a, in some cases, may identify RF resources for use in uplink and downlink communications based on a concurrency type, which may impact communications using one or both the first SIM 235 or the second SIM 240. Further, the third network entity 105-c may provide a neighboring cell to one of the first network entity 105-a or the second network entity 105-b, and may transmit reference signals 250 via downlink communications 225. Measurements from the neighboring cell may be provided with a measurement report 255 of the associated network entity 105 (e.g., if the third network entity 105-c provides a neighboring cell of the second network entity 105-b, the neighbor cell measurements would be provided using the second SIM in the measurement report 255 provided via uplink communications 220) .
[0072] In some aspects, the first SIM 235 and the second SIM 240 may operate according to an MSIM configuration. Such an MSIM configuration may provide the UE with enhanced capability for multiple different communications with multiple different networks in a concurrent manner. In order to reduce costs and hardware component space, in some cases two or more SIMs may share a same set of RF resources (e.g., RF components, baseband resources, etc. ) . Techniques such as discussed herein may allow the UE 115-a to provide measurement reports 255 that include one or more adjustments that account for communications impacts due to concurrent MSIM communications. In some cases, a measurement manager 245 at a RF connection manager 230 may schedule measurements and adjust one or more associated parameters based on impacts due to MSIM operations. For example, UE 115-a may have four available receive chains that are shared by the first SIM 235 and the second SIM 240. Depending upon a concurrency mode, the first SIM 235 and the second SIM 240 may share receive chains, or use independent receive chains. FIG. 3 illustrates an example of concurrent communications using multiple SIMs, and FIG. 4 illustrates exemplary types of RF resource sharing for multiple SIMs.
[0073] FIG. 3 shows an example of a concurrent communications 300 that supports techniques for mobility control for dual SIM devices in accordance with one or more aspects of the present disclosure. In some examples, concurrent communications 300 may be implemented by aspects of wireless communications system 100 or 200, as described with reference to FIGs. 1 and 2, or by a UE as discussed with reference to FIGs. 1 and 2. In some examples, operations illustrated in FIG. 3 may be performed by a UE that supports MSIM operation with concurrent communication on two networks (e.g., cellular networks and / or WLANs) , as described herein.
[0074] In this example, a MSIM UE may include a first SIM 305 and a second SIM 310. The first SIM 305 may provide communications with a first network and an associated first network entity (e.g., via a network device such as a RU or TRP) , and the second SIM 310 may provide communications with a second network and an associated second network entity (e.g., via a network device such as a RU or TRP) . The first SIM 305 may operate in an inactive or idle state in which periodic communications 315 may be exchanged to provide reference signals, control information, measurement reports, and the like. The first SIM 305 may also operate in an RRC connected state 320 for active communications (e.g., voice or data communications) . Similarly, the second SIM 310 may operate in an inactive or idle state in which periodic communications 325 may be exchanged, and may also operate in an RRC connected state 330 for active communications (e.g., voice or data communications) .
[0075] As discussed herein, at least a portion of communications of the first SIM 305 may be concurrent with communications of the second SIM 310. In this example, the first SIM 305 may be in the RRC connected state 320 for a first time period 335 during which the second SIM 310 is in an idle mode, and for a second time period 340 during which both the first SIM 305 and the second SIM 310 are active. In this example, the second SIM 310 may also be in the RRC connected state 330 for a third time period 345 during which the first SIM 305 is in an idle mode. Based on the concurrent communications of both the first SIM 305 and the second SIM 310, the UE may share RF resources based on UE capabilities and a concurrency type, and FIG. 4 illustrates examples of resource sharing that may be implemented.
[0076] FIG. 4 shows examples of shared RF components 400 that support techniques for mobility control for dual SIM devices in accordance with one or more aspects of the present disclosure. In some examples, shared RF components 400 may implement or be implemented by aspects of wireless communications system 100 or 200, as described with reference to FIGs. 1 and 2, or by a UE as discussed with reference to FIGs. 1 through 3. In some examples, shared RF components 400 may be used at a UE that supports MSIM operation with concurrent communication on two networks (e.g., cellular networks and / or WLANs) , as described herein.
[0077] In one example, a first exemplary MSIM concurrency type 405 may use shared RF components, such as shared RF resources 410. In one example as illustrated in FIG. 4, a UE may have four receive chains that are associated with RF resources 410, which include RF resources 410-a through 410-d associated with each receive chain. In cases where one SIM is active, as indicated at 415, a first SIM 425 may utilize all available RF resources 410. In cases where two SIMs are active, as indicated at 420, the first SIM 425 may utilize first RF resources 410-a and second RF resources 410-b, and a second SIM 430 may utilize third RF resources 410-c and fourth RF resources 410-d. Thus, when the first SIM 425 is operating in an MSIM configuration with concurrent communications with the second SIM 430, a channel capacity for communications is reduced compared to when only the first SIM 425 is active (i.e., when the second SIM 430 is idle) . However, traditional measurement reports provided by the first SIM 425 may simply provide measurement parameters (e.g., RSRP values) , and a network entity that receives such a measurement report may make mobility decisions based on the received measurement parameters under the assumption that all of the RF resources 410 are available to the UE. In accordance with various aspects discussed herein, the UE may adjust one or more reported parameters based on concurrent MSIM communications, which may result in mobility decisions of the network that reflect channel capacity at the UE when concurrent MSIM communications are present.
[0078] Another exemplary MSIM concurrency type may use independent RF components, such as independent RF resources 450. In the example of FIG. 4, the UE again may have six receive chains that are associated with RF resources 410, which include RF resources 410-a through 410-f associated with each receive chain, with each SIM having independent RF resources 410. In this example, a first SIM 465 may use first RF resources 410-a through fourth RF resources 410-d, and a second SIM 470 may use fifth RF resources 410-e and sixth RF resources 410-f. In cases where one SIM is active, as indicated at 455, a first SIM 420 may be utilize the RF resources 410-athrough 401-d, with remaining fifth RF resources 410-e and sixth RF resources 410-f being idle. In cases where both SIMs are active, as indicated at 460, the first SIM 465 may continue to utilize first through fourth RF resources 405-a through 405-d, while the second SIM 470 may utilize fifth RF resources 410-e and sixth RF resources 410-f. Such an MSIM concurrency type may provide for more accurate mobility decisions, but may underutilize available RF resources 410 in some cases. While these examples discuss receive resources, such techniques also apply to transmit resources.
[0079] Further, while four RF resources 410 are illustrated in FIG. 4, UEs may have different numbers of available RF chains. Additionally, in some cases the number of RF chains available at a UE may change (e.g., based on an operational band used by each SIM, based on thermal or RF exposure constraints, etc. ) . Table 1 illustrates RF concurrency types for two SIMs for uplink communications. It is to be understood that this example is provided for discussion and illustration and other examples may provide downlink concurrency types, may provide more SIMs, different numbers of RF chains, different sharing types, or any combinations thereof. In this example, different exemplary sharing types for one through 4 transmit chains are illustrated.
[0080] Table 1: Two SIMs RF concurrency types -uplink
[0081] As discussed herein, due to the hardware resource sharing in a MSIM device, performance of each SIM may be impacted by the other SIM, depending on the resource sharing mode and on whether uplink or downlink communications are present. As indicated above, each SIM will follow network mobility control based on network configured metrics, such as RSRP, signal to interference and noise ratio (SINR) , reference signal received quality (RSRQ) , and the like. However, network may be unaware of whether the UE is operating in an MSIM configuration with concurrent communications, and may provide mobility control based on channel conditions and network loading. Therefore, these mobility control metrics are insufficient in MSIM mobility control and performance may be enhanced for SIMs in such situations.
[0082] In one example, a first SIM on a first cell may use a first frequency band, and a second SIM on a second cell may use a second frequency band, where the first SIM and the second SIM have deep resource sharing (e.g., shared RF resources 410) . Such resource sharing may lead to first SIM performance loss by d1%compared with no concurrency (e.g., single-SIM (SSIM) operation) , and the second SIM may have a performance loss by d2%compared with no concurrency (e.g., SSIM) . Further, there may be a neighbor cell to the second cell that operates on a third frequency band, and the third frequency band may use independent RF resources (e.g., independent receive resources 450) to the first SIM, but may have lower RSRP / SINR / RSRQ than the second cell which is the current serving from the second SIM, and no measurement report can be triggered based on a network configuration. However, if the second SIM could connect with the third cell, it may lead to a g1% (g1%<d1%) loss on the first SIM and a g2%loss on the second SIM, which may be comparable with d2%or larger / less than d2%. Therefore, to this MSIM device, if the second SIM loss g2%is less than d2%, the second SIM moving to the third cell would provide enhanced performance. Further, if the second SIM loss g2%is comparable with d2%, the second SIM moving to the third cell would still be a good option since the first SIM performance is improved. Additionally, if the second SIM loss g2%is larger than d2%, the better option between staying on the second cell or moving to the third cell may be decided based on on-going traffic priority and the QoS of the traffic on each SIM. For example, is the first SIM has higher priority and the second SIM QoS can be still satisfied with g2%loss, then the second SIM moving to the third cell may be preferred, but is the second SIM g2%loss is unacceptable, staying on the second cell may be preferred.
[0083] In accordance with various aspects provided herein, the Shannon channel capacity of the neighbor cell may be used in neighbor cell evaluation and measurement report ranking, which will consider the neighbor cell bandwidth and SNR channel condition: C=BW*log2 (1+SNR) ,
[0084] where C is the channel capacity and B W is the bandwidth of the cell. The bandwidth can further consider the aggregated bandwidth based on a number of layers and bandwidths of component carriers based on history. The SNR may be based on the neighbor cell measurement only or adjusted to reflect the potential component carrier SNR based on history as well.
[0085] For an MSIM device, the channel capacity may be determined as the capacity adjusted with MSIM concurrency loss based on traffic type. Assuming the first SIM on cell-a and the second SIM on cell-b, second SIM mobility control with neighbor cell-c in consideration may be based on: C=BW*log2 (1+SNR) *scalingMSI.
[0086] The scalingMSIM will be discussed in more detail below. For data rate sensitive traffic (e.g., FTP / TCP / http) , the channel capacity may be adjusted based on the throughput loss of concurrency type between cell-a and cell-c. For latency sensitive traffic, which does not require large channel capacity, the concurrency mode which can provide reliable transmission may be favored and mapped to a smaller loss to channel capacity.
[0087] In some aspects, based on uplink and downlink resource sharing mode, the performance loss under each mode can be estimated. The impact due to resource sharing include, for example, a transmit and receive concurrency mode (e.g., whether a transmit chain is shared in TDD mode or whether a number of receive chains are reduced) ; RF device coexistence (e.g., a first SIM transmission may cause desensitization of a reception on a second SIM, and coexistence handling may be used which may also lead to performance difference) ; and RF device quality imparity (e.g., on certain bands, one SIM may only get RF resources with relatively poorer performance due to device differences) . Other factors also may impact performance due to resource sharing.
[0088] A UE may calculate the potential capacity of the neighbor cell (cell-c) and adjust the measurement RSRP or ranking accordingly to reflect the MSIM concurrency preference, which may result in desired mobility control (referred to as MSIM mobility control) . Such measurement report adjustments may be used in connected mode measurement control or idle cell selection / reselection when both SIMs are in connected mode (DSDA) or any SIM is in connected / idle mode only. Table 2 illustrates an exemplary mapping of MSIM concurrency types (numbered one through seven) with an uplink concurrency operation, downlink concurrency operation, and associated uplink and downlink losses. The uplink concurrency operations may include full-concurrency (FC) , shared transmit (TxS) , no concurrency, FC with coexistence (e.g., interference cancellation) , and FC with transmit chain imparity. The downlink concurrency operations may include no receive downgrade, receive downgrade, no concurrency, or no receive downgrade with coexistence.
[0089] Table 2: MSIM concurrency types mapping
[0090] As indicated, such techniques may be applicable to connected measurement control or idle cell selection / reselection when both SIMs in connected mode (DSDA) or any SIM in connected / idle mode only. In some cases, techniques for measurement adjustments may be performed based on a MSIM state of the UE (e.g., when the UE is in a DSDA state) , such as illustrated in Table 3 in which DSDA corresponds to dual SIM dual active, and DSDS corresponds to dual SIM dual standby:
[0091] Table 3: Mapping of SIM states to MSIM states
[0092] In some aspects, one SIM, such as lower priority SIM, may be selected to apply the MSIM mobility control with MSIM channel capacity impact and the other SIM may follow mobility control without MSIM consideration. In some cases, the selected SIM to apply the MSIM mobility control may be based on a traffic priority or traffic QoS associated with communications at the SIM. For example, a SIM with an active voice call may be set to a higher priority than another SIM with packet switched traffic (e.g., eMBB) , due to the voice traffic having higher QoS targets. In such an example, the SIM with the packet switched traffic may apply MSIM mobility control. In another example, both SIMs may be in a voice call but one SIM is in active state and the other SIM is in hold call state. In such an example, the call holding SIM can be selected to apply MSIM mobility control. In a further example, one SIM may be in connected mode and the other SIM in idle mode, and the higher priority SIM may be selected as the connected mode SIM with full buffer throughput traffic if its performance has been impacted by the presence of the idle SIM. In further aspects, measurement scheduling may be adjusted based on MSIM concurrency. An example of such an aspect is illustrated in FIG. 5.
[0093] FIG. 5 shows an example of measurement object scheduling 500 that supports techniques for mobility control for dual SIM devices in accordance with one or more aspects of the present disclosure. In some examples, measurement object scheduling 500 may be implemented by aspects of wireless communications system 100 or 200, as described with reference to FIGs. 1 and 2, or by a UE as discussed with reference to FIGs. 1 through 4. In some examples, measurement object scheduling 500 may be used at a UE that supports MSIM operation with concurrent communication on two networks (e.g., cellular networks and / or WLANs) , as described herein.
[0094] In the example of FIG. 5, in measurement scheduling, the measurement sequence of neighbor cells can be ordered according to a concurrency type at the SIM and the serving cell or band of the other SIM. Because measurement metrics (e.g., SNR metric) of the neighbor cell (s) is unavailable before measurement, a measurement scheduling sequence may not be based on an accurate capacity calculation, and may instead rely on information such as bandwidth, MSIM traffic, concurrency type, or any combinations thereof. In this example, a set of network configured measurement objects 505 may include a first measurement object 520-a through a kth measurement object 520-k, ordered sequentially from a through k. The order of the measurement objects 520 may be adjusted based on bandwidth to provide measurement object scheduling based on bandwidth 510, in which a third measurement object 520-c associated with a higher bandwidth is ordered ahead of the remaining measurement objects in this example. Further, the order of the measurement objects 520 may be adjusted based on concurrency type to provide measurement object scheduling based on bandwidth and concurrency type 515, in which the first measurement object 520-a associated with a first concurrency type (e.g., FC with independent Rx) is ordered ahead of a second concurrency type (e.g., TxS with shared Rx) , and a third concurrency type (e.g., TxS with independent Rx) .
[0095] Such techniques may provide scheduling of measurements in which more preferred cells are measured ahead of other cells. For example, a larger bandwidth neighboring cell may provide higher channel capacity and the UE, based on historical information associated with the neighboring cells, may schedule neighboring cells with larger bandwidth (e.g., based on configured frequency bandwidth, a quantity of secondary component carriers (SCCs) or layers, favorable scheduling patterns, or any combinations thereof) to be measured ahead of cells with lower bandwidths. Further, for MSIM operations, different concurrency types may provide more enhanced performance than other concurrency types (e.g., the Rx independent and Tx full concurrency (type-1) may provide the best performance) and associated measurement objects may be ranked in accordance with associated concurrency types. In some cases, the sequence of measurement objects first may be ordered from highest to lowest bandwidth, and then from most favorable to least favorable concurrency types. Such techniques may provide measurement scheduling based on an aggregated consideration of potential capacity, and the cell measurement sequence can be ranked from high to low based on relative static metrics, such as bandwidth and concurrency type. Further, a priority associated with the SIM may be used to determine the sequence of measurement objects (e.g., concurrency types that provide higher receive throughput may be preferred for traffic associated with more relaxed latency or QoS targets) .
[0096] As discussed with reference to FIG. 4, in some aspects the Shannon channel capacity for a SIM may be estimated. As discussed, channel capacity may be estimated according to: C=BW*log2 (1+SNR) *scalingMSIM
[0097] in which the MSIM concurrency impact is used in evaluation of a neighbor cell channel capacity. To further map measurement objects to the neighbor cell measured RSRP metric, some scaling may be further applied by below equation: MO_RankMSIM=rsrpN, MSIM of the best cell+Rank_OffMSIM where the RSRP of the best cell provides a comparison between the neighbor cells and current serving cell, and the rank offset provides a comparison among other neighbor cells, and Rank_OffseMSIM =K*log2 (LPcell*BWPcell*log2 (SINRPcell+1) *scali DSDA) =Rank_Offset+ΔMSIM
[0098] where, K is a constant, and Rank_Offset=K*log2 (LPcell*BWPcell*log2 (SINRPcell+1) ) ,
[0099] which considers bandwidth and SINR only, and ΔMSIM=K*G*log2 (scalingMSIM) ,
[0100] which considers MSIM concurrency impact.
[0101] Further, the scaling factor may be determined as: scaliMSIM=wDL* (1-lossDL) +wUL* (1-lossUL)
[0102] where different uplink and downlink concurrency types may lead to different performance loss based on traffic type. For example, receive chain sharing may lead to downlink throughput loss but have less impact to uplink throughput. Therefore, in some cases, in the MSIM impact to the channel capacity, uplink and downlink concurrency impact are calculated based on the traffic type of the SIM in accordance with Table 4:
[0103] Table 4: Traffic type and weights
[0104] The term rsrpN, MSIM in the above equation may be used to indicate the MSIM concurrency difference between the serving cell and the neighbor cell, which may be mapped to a neighbor cell RSRP adjustment of measured RSRP as:
[0105] where, Rank_OffsMSIM (Ncell) =K*log2 (LNcell*BWNcell*log2 (SINRNcell+1) * scalingMSIM (Ncell) ) =Rank_Offset (Ncell) +ΔMSIM (Ncell) , and Rank_OffsetMSIM (Scell) =K*log2 (LScell*BWScell*log2 (SINRScell+1) * scalingMSIM (Scell) ) =Rank_Offset (Scell) +ΔMSIM (Scell) .
[0106] The rsrpN, MSIM may be used instead of measured rsrpN in the measurement report and measurement report ranking of neighbor cells. Based on serving and neighbor cell MSIM concurrency type, one example of the ΔMSIM=K*log2 (scalingMSIM) is a fixed value by lookup table with K=2. An example of a ΔMSIM lookup table is provided in Table 5.
[0107] Table 5 -ΔMSIM lookup table
[0108] FIG. 6 shows an example of a measurement parameter adjustment 600 that supports techniques for mobility control for dual SIM devices in accordance with one or more aspects of the present disclosure. In some examples, measurement parameter adjustment 600 may be implemented by aspects of wireless communications system 100 or 200, as described with reference to FIGs. 1 and 2, or by a UE as discussed with reference to FIGs. 1 through 5. In some examples, measurement parameter adjustment 600 may be used at a UE that supports MSIM operation with concurrent communication on two networks (e.g., cellular networks and / or WLANs) , as described herein.
[0109] In the example of FIG. 6, adjustments are provided for a higher priority SIM, which has higher priority than another SIM (e.g., based on a traffic type of the SIMs, or QoS targets of the SIMs) . In this example, the higher priority SIM may take measurements of a serving cell 605 and obtain a measurement parameter, such as RSRPs 610. The higher priority SIM also may measure neighbor cells 615 and obtain associated measurement parameters, such as RSRPN1 620-a through RSRPNk 620-k. The measurement parameters may be ordered based on RSRP as indicated at 625, to identify an order of associated measurement objects such as RSRPN_MO1 630-a through RSRPM_Moi 630-i. The measurement objects may be further ordered based on rank offset, as indicated at 635, to determine a measurement report ordering of RSRP for the measurement objects. In the example of FIG. 6, the rank offset may adjust the order to be RSRPN_MO1 630-a, RSRPN_MOi 630-i, RSRPN_MO2 630-b, ... In some cases, the ranking for measurement objects may be: MO_Rank = Measured RSRP of the best Cell + Rank_Offset, where Rank_Offset = K*G*Log2 [LPCell*BWPCell*Log2 (SINRPCell+1) ] , as discussed above.
[0110] FIG. 7 shows an example of a measurement parameter adjustment 700 that supports techniques for mobility control for dual SIM devices in accordance with one or more aspects of the present disclosure. In some examples, measurement parameter adjustment 700 may be implemented by aspects of wireless communications system 100 or 200, as described with reference to FIGs. 1 and 2, or by a UE as discussed with reference to FIGs. 1 through 6. In some examples, measurement parameter adjustment 700 may be used at a UE that supports MSIM operation with concurrent communication on two networks (e.g., cellular networks and / or WLANs) , as described herein.
[0111] In the example of FIG. 7, adjustments are provided for a lower priority SIM, which has lower priority than another SIM (e.g., based on a traffic type of the SIMs, or QoS targets of the SIMs) . In this example, the lower priority SIM may take measurements of a serving cell 705 and obtain a measurement parameter, such as RSRPs 710. The higher priority SIM also may measure neighbor cells 715 and obtain associated measurement parameters, such as RSRPN1 720-a through RSRPNk 720-k. The lower priority SIM may perform MSIM adjustment 725 based on adjustments 730-athrough 730-k for a concurrency type of the associated neighbor cells 715 and serving cell 705. The adjustments may provide adjusted RSRPs 735, including RSRPN1, MSIM 740-a through RSRPNk, MSIM 740-k. The adjusted RSRPs 735 may be ordered based on RSRP and the MSIM adjustment, as indicated at 745, to identify an order of associated measurement objects such as RSRPN_MO1, MSIM 750-a through RSRPM_MOi, MSIM 750-i. The measurement objects may be further ordered based on rank offset, as indicated at 755, to determine a measurement report ordering of RSRP for the measurement objects. In the example of FIG. 7, the rank offset may adjust the order to be RSRPN_MO2 760-b, RSRPN_MOi 760-i, RSRPN_MO1 760-a, ... In some cases, the ranking for measurement objects may be: MO_Rank = RSRP with DSDA adjustment of the best Cell +Rank_Offset, where Rank_Offset = K*G*Log2 [LPCell*BWPCell*Log2 (SINRPCell+1) ] +Δdsda (m, k) , as discussed above.
[0112] FIG. 8 shows a block diagram 800 of a device 805 that supports techniques for mobility control for dual SIM devices in accordance with one or more aspects of the present disclosure. The device 805 may be an example of aspects of a UE 115 as described herein. The device 805 may include a receiver 810, a transmitter 815, and a communications manager 820. The device 805, or one or more components of the device 805 (e.g., the receiver 810, the transmitter 815, and the communications manager 820) , may include at least one processor, which may be coupled with at least one memory, to, individually or collectively, support or enable the described techniques. Each of these components may be in communication with one another (e.g., via one or more buses) .
[0113] The receiver 810 may provide a means for receiving information such as packets, user data, control information, or any combination thereof associated with various information channels (e.g., control channels, data channels, information channels related to techniques for mobility control for dual SIM devices) . Information may be passed on to other components of the device 805. The receiver 810 may utilize a single antenna or a set of multiple antennas.
[0114] The transmitter 815 may provide a means for transmitting signals generated by other components of the device 805. For example, the transmitter 815 may transmit information such as packets, user data, control information, or any combination thereof associated with various information channels (e.g., control channels, data channels, information channels related to techniques for mobility control for dual SIM devices) . In some examples, the transmitter 815 may be co-located with a receiver 810 in a transceiver module. The transmitter 815 may utilize a single antenna or a set of multiple antennas.
[0115] The communications manager 820, the receiver 810, the transmitter 815, or various combinations thereof or various components thereof may be examples of means for performing various aspects of techniques for mobility control for dual SIM devices as described herein. For example, the communications manager 820, the receiver 810, the transmitter 815, or various combinations or components thereof may be capable of performing one or more of the functions described herein.
[0116] In some examples, the communications manager 820, the receiver 810, the transmitter 815, or various combinations or components thereof may be implemented in hardware (e.g., in communications management circuitry) . The hardware may include at least one of a processor, a digital signal processor (DSP) , a central processing unit (CPU) , an application-specific integrated circuit (ASIC) , a field-programmable gate array (FPGA) or other programmable logic device, a microcontroller, discrete gate or transistor logic, discrete hardware components, or any combination thereof configured as or otherwise supporting, individually or collectively, a means for performing the functions described in the present disclosure. In some examples, at least one processor and at least one memory coupled with the at least one processor may be configured to perform one or more of the functions described herein (e.g., by one or more processors, individually or collectively, executing instructions stored in the at least one memory) .
[0117] Additionally, or alternatively, the communications manager 820, the receiver 810, the transmitter 815, or various combinations or components thereof may be implemented in code (e.g., as communications management software or firmware) executed by at least one processor. If implemented in code executed by at least one processor, the functions of the communications manager 820, the receiver 810, the transmitter 815, or various combinations or components thereof may be performed by a general-purpose processor, a DSP, a CPU, an ASIC, an FPGA, a microcontroller, or any combination of these or other programmable logic devices (e.g., configured as or otherwise supporting, individually or collectively, a means for performing the functions described in the present disclosure) .
[0118] In some examples, the communications manager 820 may be configured to perform various operations (e.g., receiving, obtaining, monitoring, outputting, transmitting) using or otherwise in cooperation with the receiver 810, the transmitter 815, or both. For example, the communications manager 820 may receive information from the receiver 810, send information to the transmitter 815, or be integrated in combination with the receiver 810, the transmitter 815, or both to obtain information, output information, or perform various other operations as described herein.
[0119] The communications manager 820 may support wireless communication in accordance with examples as disclosed herein. For example, the communications manager 820 is capable of, configured to, or operable to support a means for establishing a first connection with a first network device using a first SIM or Wi-Fi module. The communications manager 820 is capable of, configured to, or operable to support a means for establishing a second connection with a second network device using a second SIM, the first connection and the second connection configured for concurrent communications with the first network device and the second network device, respectively, where the first connection and the second connection use a first subset of RF components at the UE. The communications manager 820 is capable of, configured to, or operable to support a means for transmitting a measurement report that is based on one or more channel measurements of a third network device using the second SIM, where concurrent communications with the third network device and the first network device use the first subset of RF components or a second subset of RF components, and one or more channel measurements of the third network device are adjusted based on an estimated channel capacity of the third network device, and where the estimated channel capacity of the third network device is adjusted based on a concurrency loss associated with the first subset of RF components or the second subset of RF components.

[0227] The description set forth herein, in connection with the appended drawings, describes example configurations and does not represent all the examples that may be implemented or that are within the scope of the claims. The term “example” used herein means “serving as an example, instance, or illustration, ” and not “preferred” or “advantageous over other examples. ” The detailed description includes specific details for the purpose of providing an understanding of the described techniques.
