[0004] Various aspects of this disclosure generally relate to wireless communication, and specifically to techniques and apparatus for configuring transmit power parameters after tuning back to subscription in a dual connectivity mode.

[0005] Related technical descriptions

[0006] Wireless communication systems are widely deployed to provide a variety of telecommunications services such as telephone, video, data, messaging, and broadcasting. Typical wireless communication systems employ multiple access technologies that can support communication with multiple users by sharing available system resources (e.g., bandwidth, transmit power). Examples of such multiple access technologies include Code Division Multiple Access (CDMA) systems, Time Division Multiple Access (TDMA) systems, Frequency Division Multiple Access (FDMA) systems, Orthogonal Frequency Division Multiple Access (OFDMA) systems, Single Carrier Frequency Division Multiple Access (SC-FDMA) systems, Time Division Synchronous Code Division Multiple Access (TD-SCDMA) systems, and Long Term Evolution (LTE). LTE / LTE-Advanced is an enhancement set of the Universal Mobile Telecommunications System (UMTS) mobile standard issued by the 3rd Generation Partnership Project (3GPP).

[0007] A wireless network may include several base stations (BSs) capable of supporting communication between several user equipments (UEs). UEs can communicate with the BS via downlink and uplink. The downlink (or forward link) refers to the communication link from the BS to the UE, while the uplink (or reverse link) refers to the communication link from the UE to the BS. As will be described in more detail herein, the BS may be referred to as a B-node, gNB, access point (AP), radio headend, transmit / receive point (TRP), new radio (NR) BS, 5G B-node, etc.

[0008] The above multiple access technologies have been adopted in various telecommunications standards to provide a common protocol enabling different user equipment to communicate at the city, country, region, and even global levels. NR (which can also be referred to as 5G) is an enhancement set of the LTE mobile standard issued by 3GPP. NR is designed to better support mobile broadband Internet access by using Orthogonal Frequency Division Multiplexing (OFDM) with a Cyclic Prefix (CP) (CP-OFDM) on the downlink (DL), and using CP-OFDM and / or SC-FDM (e.g., also known as Discrete Fourier Transform Extended OFDM (DFT-s-OFDM)) on the uplink (UL), as well as supporting beamforming, multiple-input multiple-output (MIMO) antenna technologies and carrier aggregation to improve spectral efficiency, reduce costs, improve service, utilize new spectrum, and better integrate with other open standards. Further improvements to LTE, NR, and other radio access technologies remain useful as the demand for mobile broadband access continues to grow.

[0026] Detailed description

[0027] The various aspects of this disclosure are described more fully below with reference to the accompanying drawings. However, this disclosure may be implemented in many different forms and should not be construed as being limited to any specific structure or function given throughout this disclosure. Rather, these aspects are provided so that this disclosure will be thorough and complete, and will fully convey the scope of this disclosure to those skilled in the art. Based on the teachings herein, those skilled in the art will appreciate that the scope of this disclosure is intended to cover any aspect of this disclosure disclosed herein, whether implemented independently of or in combination with any other aspect of this disclosure. For example, any number of aspects set forth herein may be used to implement an apparatus or practice. Furthermore, the scope of this disclosure is intended to cover such apparatuses or methods practiced using additional structures, functionalities, or structures and functionalities that complement or supplement the various aspects of this disclosure set forth herein. It should be understood that any aspect of this disclosure disclosed herein may be implemented by one or more elements of the claims.

[0028] Several aspects of a telecommunications system will now be described with reference to various devices and techniques. These devices and techniques will be described in the following detailed description and explained in the accompanying drawings by various blocks, modules, components, circuits, steps, processes, algorithms, etc. (collectively, "elements"). These elements can be implemented using hardware, software, or a combination thereof. Whether such elements are implemented as hardware or software depends on the specific application and the design constraints imposed on the overall system.

[0029] It should be noted that although the aspects herein may be described using terms commonly associated with 5G or NR radio access technology (RAT), the aspects of this disclosure may be applied to other RATs, such as 3G RAT, 4G RAT, and / or RATs after 5G (e.g., 6G).

[0030] Figure 1This is a diagram illustrating an example of a wireless network 100 according to this disclosure. The wireless network 100 may be a 5G (NR) network and / or an LTE network, etc., or may include its elements. The wireless network 100 may include several base stations 110 (shown as BS110a, BS 110b, BS 110c, and BS 110d) and other network entities. A base station (BS) is an entity that communicates with a user equipment (UE) and may also be referred to as an NR BS, B-node, gNB, 5G B-node (NB), access point, transmit / receive point (TRP), etc. Each BS may provide communication coverage for a specific geographic area. In 3GPP, the term "cell" may refer to the coverage area of ​​a BS and / or the BS subsystem serving that coverage area, depending on the context in which the term is used.

[0031] A BS can provide communication coverage for macrocells, picocells, femtocells, and / or another type of cell. Macrocells can cover a relatively large geographic area (e.g., a radius of several kilometers) and allow unrestricted access by UEs with a service subscription. Picocells can cover a relatively small geographic area and allow unrestricted access by UEs with a service subscription. Femtocells can cover a relatively small geographic area (e.g., a residential area) and allow restricted access by UEs associated with that femtocell (e.g., UEs in a Closed Subscriber Group (CSG)). A BS used for macrocells may be referred to as a macro BS. A BS used for picocells may be referred to as a pico BS. A BS used for femtocells may be referred to as a femto BS or a home BS. Figure 1 In the example shown, BS 110a can be a macro BS for macro cell 102a, BS 110b can be a pico BS for pico cell 102b, and BS 110c can be a femto BS for femto cell 102c. A BS can support one or more (e.g., three) cells. The terms “eNB,” “base station,” “NR BS,” “gNB,” “TRP,” “AP,” “B node,” “5G NB,” and “cell” are used interchangeably herein.

[0032] In some respects, the cell may not be stationary, and the geographical area of ​​the cell may move depending on the location of the mobile BS. In some respects, BSs may interconnect with each other and / or interconnect to one or more other BSs or network nodes (not shown) in the wireless network 100 via various types of backhaul interfaces (such as direct physical connections or virtual networks, using any suitable transport network).

[0033] The wireless network 100 may also include a relay station. A relay station is an entity capable of receiving data transmissions from an upstream station (e.g., a BS or a UE) and transmitting those data transmissions to a downstream station (e.g., a UE or a BS). A relay station may also be a UE capable of relaying transmissions for other UEs. Figure 1 In the example shown, relay BS 110d can communicate with macro BS 110a and UE 120d to facilitate communication between BS 110a and UE 120d. A relay BS can also be referred to as a relay station, relay base station, relay, etc.

[0034] Wireless network 100 can be a heterogeneous network comprising different types of Base Stations (BSs) such as macro BSs, pico BSs, femto BSs, relay BSs, etc. These different types of BSs may have different transmit power levels, different coverage areas, and different effects on interference in wireless network 100. For example, macro BSs may have high transmit power levels (e.g., 5 to 40 watts), while pico BSs, femto BSs, and relay BSs may have lower transmit power levels (e.g., 0.1 to 2 watts).

[0035] Network controller 130 can be coupled to a set of BSs and can provide coordination and control over these BSs. Network controller 130 can communicate with each BS via backhaul. These BSs can also communicate with each other directly or indirectly, for example, via wireless or wired backhaul.

[0036] UE 120 (e.g., 120a, 120b, 120c) may be distributed throughout the wireless network 100, and each UE may be stationary or mobile. UE may also be referred to as an access terminal, terminal, mobile station, subscriber unit, station, etc. UE may be a cellular phone (e.g., a smartphone), personal digital assistant (PDA), wireless modem, wireless communication device, handheld device, laptop computer, cordless phone, wireless local loop (WLL) station, tablet, camera, gaming device, netbook, smartbook, ultrabook, medical device or equipment, biometric sensor / device, wearable device (smartwatch, smart clothing, smart glasses, smart wristband, smart jewelry (e.g., smart ring, smart bracelet)), entertainment device (e.g., music or video device, or satellite radio), vehicle component or sensor, smart meter / sensor, industrial manufacturing equipment, GPS device, or any other suitable device configured to communicate via wireless or wired media.

[0037] Some UEs may be considered machine-type communication (MTC) devices or evolved or enhanced machine-type communication (eMTC) UEs. MTC and eMTC UEs include, for example, robots, drones, remote devices, sensors, instruments, monitors, and / or location tags that can communicate with a base station, another device (e.g., a remote device), or some other entity. Wireless nodes may provide connectivity to or to a network (e.g., a wide area network, such as the Internet or a cellular network) via wired or wireless communication links, for example. Some UEs may be considered Internet of Things (IoT) devices and / or may be implemented as NB-IoT (Narrowband Internet of Things) devices. Some UEs may be considered customer premises equipment (CPE). UE 120 may be included within a housing that houses components of UE 120, such as processor components and / or memory components. In some aspects, the processor components and memory components may be coupled together. For example, the processor components (e.g., one or more processors) and memory components (e.g., memory) may be operatively coupled, communicatively coupled, electronically coupled, and / or electrically coupled.

[0038] Generally, any number of wireless networks can be deployed in a given geographical area. Each wireless network can support a specific RAT and can operate on one or more frequencies. A RAT can also be referred to as a radio technology, air interface, etc. A frequency can also be referred to as a carrier, frequency channel, etc. Each frequency can support a single RAT in a given geographical area to avoid interference between wireless networks using different RATs. In some cases, NR or 5G RAT networks can be deployed.

[0039] In some respects, two or more UEs 120 (e.g., shown as UE 120a and UE 120e) may communicate directly using one or more sidelink channels (e.g., without using base station 110 as an intermediary). For example, UEs 120 may communicate using peer-to-peer (P2P) communication, device-to-device (D2D) communication, vehicle-to-everything (V2X) protocols (e.g., which may include vehicle-to-vehicle (V2V) protocols or vehicle-to-infrastructure (V2I) protocols), and / or mesh networks. In this scenario, UEs 120 may perform scheduling operations, resource selection operations, and / or other operations described elsewhere herein as performed by base station 110.

[0040] Devices in the wireless network 100 can communicate using the electromagnetic spectrum, which can be subdivided into various categories, bands, channels, etc., based on frequency or wavelength. For example, devices in the wireless network 100 can communicate using an operating band with a first frequency range (FR1) and / or an operating band with a second frequency range (FR2), where the first frequency range (FR1) spans from 410 MHz to 7.125 GHz and the second frequency range (FR2) spans from 24.25 GHz to 52.6 GHz. The frequencies between FR1 and FR2 are sometimes referred to as intermediate frequency bands. Although a portion of FR1 is greater than 6 GHz, FR1 is often referred to as the "sub-6 GHz" band. Similarly, although different from the extremely high frequency (EHF) band (30 GHz–300 GHz) designated as the "millimeter wave" band by the International Telecommunication Union (ITU), FR2 is often referred to as the "millimeter wave" band. Therefore, unless otherwise stated, it should be understood that, if used herein, the terms "sub-6 GHz" and the like can broadly refer to frequencies less than 6 GHz, frequencies within FR1, and / or intermediate frequency band frequencies (e.g., greater than 7.125 GHz). Similarly, unless otherwise stated, it should be understood that, if used herein, the terms "millimeter wave" and the like can broadly refer to frequencies within the EHF band, frequencies within FR2, and / or intermediate frequency band frequencies (e.g., less than 24.25 GHz). It is conceivable that the frequencies included in FR1 and FR2 can be modified, and the techniques described herein are applicable to those modified frequency ranges.

[0041] As indicated above, Figure 1 This is provided as an example. Other examples may differ from the one provided. Figure 1 The example described.

[0042] Figure 2 This is a diagram illustrating an example 200 of communication between a base station 110 and a UE 120 in a wireless network 100 according to this disclosure. The base station 110 may be equipped with T antennas 234a to 234t, while the UE 120 may be equipped with R antennas 252a to 252r, wherein generally T≥1 and R≥1.

[0043] At base station 110, transmit processor 220 can receive data destined for one or more UEs from data source 212, select one or more modulation and coding schemes (MCS) for each UE based at least in part on channel quality indicators (CQI) received from each UE, process (e.g., encode and modulate) the data for each UE based at least in part on the MCS selected for each UE, and provide data symbols for all UEs. Transmit processor 220 can also process system information (e.g., semi-static resource allocation information (SRPI)) and control information (e.g., CQI requests, grants, and / or upper-layer signaling), and provide overhead symbols and control symbols. Transmit processor 220 can also generate reference symbols for reference signals (e.g., cell-specific reference signals (CRS) or demodulation reference signals (DMRS)) and synchronization signals (e.g., primary synchronization signal (PSS) or secondary synchronization signal (SSS)). The transmit (TX) multiple-input multiple-output (MIMO) processor 230 can perform spatial processing (e.g., precoding) on ​​data symbols, control symbols, overhead symbols, and / or reference symbols, where applicable, and can provide T output symbol streams to T modulators (MODs) 232a to 232t. Each modulator 232 can process its respective output symbol stream (e.g., for OFDM) to obtain an output sample stream. Each modulator 232 can further process (e.g., convert to analog, amplify, filter, and up-convert) the output sample stream to obtain a downlink signal. The T downlink signals from modulators 232a to 232t can be transmitted via T antennas 234a to 234t, respectively.

[0044] At UE 120, antennas 252a to 252r can receive downlink signals from base station 110 and / or other base stations and can provide the received signals to demodulators (DEMODs) 254a to 254r respectively. Each demodulator 254 can condition (e.g., filter, amplify, downconvert, and digitize) the received signal to obtain an input sample. Each demodulator 254 can further process the input sample (e.g., for OFDM) to obtain received symbols. MIMO detector 256 can obtain the received symbols from all R demodulators 254a to 254r, perform MIMO detection on these received symbols where applicable, and provide detected symbols. Receiver processor 258 can process (e.g., demodulate and decode) these detected symbols, provide decoded data for UE 120 to data sink 260, and provide decoded control information and system information to controller / processor 280. The term "controller / processor" can refer to one or more controllers, one or more processors, or a combination thereof. The channel processor can determine parameters such as Reference Signal Received Power (RSRP), Received Signal Strength Indicator (RSSI), Reference Signal Received Quality (RSRQ), and / or CQI. In some respects, one or more components of the UE 120 may be included in the housing 284.

[0045] Network controller 130 may include communication unit 294, controller / processor 290, and memory 292. Network controller 130 may include one or more devices, such as those in a core network. Network controller 130 may communicate with base station 110 via communication unit 294.

[0046] Antennas (e.g., antennas 234a to 234t and / or antennas 252a to 252r) may include, or be included therein, one or more antenna panels, antenna groups, antenna element sets, and / or antenna arrays. Antenna panels, antenna groups, antenna element sets, and / or antenna arrays may include one or more antenna elements. Antenna panels, antenna groups, antenna element sets, and / or antenna arrays may include coplanar antenna element sets and / or non-coplanar antenna element sets. Antenna panels, antenna groups, antenna element sets, and / or antenna arrays may include antenna elements within a single housing and / or multiple antenna elements within housings. Antenna panels, antenna groups, antenna element sets, and / or antenna arrays may include elements coupled to one or more transmission and / or reception components (such as...). Figure 2 One or more antenna elements (one or more components).

[0047] On the uplink, at UE 120, transmit processor 264 can receive and process data from data source 262 and control information from controller / processor 280 (e.g., reports including RSRP, RSSI, RSRQ, and / or CQI). Transmit processor 264 can also generate reference symbols for one or more reference signals. Symbols from transmit processor 264 may be pre-encoded by TX MIMO processor 266 where applicable, further processed by modulators 254a to 254r (e.g., for DFT-s-OFDM or CP-OFDM), and transmitted to base station 110. In some aspects, modulators and demodulators (e.g., MOD / DEMOD 254) of UE 120 may be included in the modem of UE 120. In some aspects, UE 120 includes a transceiver. The transceiver may include any combination of antennas 252, modulators and / or demodulators 254, MIMO detectors 256, receiver processors 258, transmitter processors 264, and / or TX MIMO processors 266. The transceiver may be used by a processor (e.g., controller / processor 280) and memory 282 to perform aspects of any of the methods described herein.

[0048] At base station 110, uplink signals from UE 120 and other UEs can be received by antenna 234, processed by demodulator 232, detected by MIMO detector 236 where applicable, and further processed by receiver processor 238 to obtain decoded data and control information transmitted by UE 120. Receiver processor 238 can provide the decoded data to data sink 239 and the decoded control information to controller / processor 240. Base station 110 may include communication unit 244 and communicate with network controller 130 via communication unit 244. Base station 110 may include scheduler 246 to schedule UE 120 for downlink and / or uplink communications. In some aspects, the modulator and demodulator (e.g., MOD / DEMOD 232) of base station 110 may be included in the modem of base station 110. In some aspects, base station 110 includes a transceiver. The transceiver may include any combination of antennas 234, modulators and / or demodulators 232, MIMO detectors 236, receiver processors 238, transmitter processors 220, and / or TX MIMO processors 230. The transceiver may be used by a processor (e.g., controller / processor 240) and memory 242 to perform aspects of any of the methods described herein.

[0049] The controller / processor 240 of base station 110, the controller / processor 280 of UE 120, and / or Figure 2Any other component may perform one or more techniques associated with configuring transmit power parameters after tuning back to the subscription in dual-connectivity mode, as described in more detail elsewhere in this document. For example, the controller / processor 240 of base station 110, the controller / processor 280 of UE 120, and / or Figure 2 Any other component that can execute or direct, for example Figure 7 The operation of process 700 and / or other processes as described herein. Memory 242 and 282 may store data and program code for base station 110 and UE 120, respectively. In some aspects, memory 242 and / or memory 282 may include: a non-transitory computer-readable medium storing one or more instructions (e.g., code and / or program code) for wireless communication. For example, when executed by one or more processors of base station 110 and / or UE 120 (e.g., direct execution, or execution after compilation, transformation, and / or interpretation), the one or more processors, UE 120, and / or base station 110 may cause the one or more processors, UE 120, and / or base station 110 to perform or direct, for example... Figure 7 The operation of process 700 and / or other processes as described herein. In some aspects, the execution instructions may include run instructions, translate instructions, compile instructions, and / or interpret instructions.

[0050] In some aspects, the UE includes: means for establishing a first connection of a first RAT, the first connection being associated with a first subscription of the UE; means for establishing a second connection of a second RAT, the second connection being associated with the first subscription of the UE; means for establishing a third connection of a third RAT, the third connection being associated with a second subscription of the UE; means for tuning away from the first connection to receive communications via the third connection; means for tuning back from the third connection to the first connection; or means for configuring transmit power parameters of the first connection at least in part based on time averaging parameters. Means for the UE to perform the operations described herein may include, for example, one or more of antenna 252, demodulator 254, MIMO detector 256, receive processor 258, transmit processor 264, TX MIMO processor 266, modulator 254, controller / processor 280, or memory 282.

[0057] In some aspects, the UE includes: means for determining a value of the transmit power parameter to be modified based at least in part on the difference between a first PL RS and a second PL RS satisfying a PLRS change threshold or the difference between a first RSRP and a second RSRP satisfying an RSRP change threshold.

[0058] In some aspects, the UE includes: means for configuring transmit power parameters for transmission via a data channel of the first connection based at least in part on ignoring one or more transmit power control commands received for the first connection after tuning back to the first connection; or means for configuring transmit power parameters for transmission via a control channel of the first connection based at least in part on applying one or more transmit power control commands received for the first connection after tuning back to the first connection.

[0059] In some aspects, the UE includes: means for receiving one or more transmit power control commands for the first connection after tuning back to the first connection; or means for ignoring one or more transmit power control commands at least in part based on a determination that applying one or more transmit power control commands would impose a limitation on transmit power parameters transmitted via the second connection.

[0060] In some aspects, the UE includes: means for receiving one or more transmit power control commands for the first connection after tuning back to the first connection; or means for applying one or more transmit power control commands based at least in part on a determination that applying one or more transmit power control commands will not impose a limitation on transmit power parameters transmitted via the second connection.

[0061] although Figure 2 The boxes in the diagram are interpreted as different components, but the functions described above with respect to these boxes can be implemented using a single hardware component, software component, or combination of components. For example, the functions described with respect to transmit processor 264, receive processor 258, and / or TX MIMO processor 266 can be performed by controller / processor 280 or under the control of controller / processor 280.

[0062] As indicated above, Figure 2 This is provided as an example. Other examples may differ from the one provided. Figure 2 The example described.

[0063] Figure 3 This is a diagram illustrating example 300 of a UE adapting its transmit power on a mobile integration window to meet one or more radio frequency (RF) radiation exposure limits according to this disclosure.

[0064] Because UEs can emit RF waves, microwaves, and / or other radiation, they are typically subject to regulatory RF safety requirements that specify particular guidelines or exposure limits governing the various operations a UE can perform. For example, RF emissions typically increase when a UE is transmitting, and can increase further when the UE is performing frequent, high-power transmissions, etc. Accordingly, since frequent and / or high-power transmissions can lead to significant RF emissions, regulatory agencies (e.g., the Federal Communications Commission (FCC) in the United States) can provide information regarding acceptable RF radiation exposure when a UE is communicating using different radio access technologies.

[0065] In some examples, RF exposure can be expressed as a specific absorption rate (SAR), which measures the energy absorbed per unit mass of human tissue and may have units of watts per kilogram (W / kg). For example, when a UE is communicating using a RAT operating in a frequency range below 6 GHz, applicable RF exposure parameters may include SAR. Specifically, SAR requirements generally specify that the total radiated power of the UE should be kept below a certain level to limit the heat generation that may occur when RF energy is absorbed. Because SAR exposure can be used to assess RF exposure at transmission frequencies below 6 GHz, SAR exposure limits typically cover wireless communication technologies such as 2G / 3G (e.g., CDMA), 4G (e.g., 3GPP Long Term Evolution (LTE)), certain 5G bands (e.g., NR in the 6 GHz band), IEEE 802.11ac, and other wireless communication technologies.

[0066] RF exposure can also be expressed in terms of power density (PD), which measures the energy absorbed per unit area and can be expressed in mW / cm². 2 It is expressed in units. For example, when a UE is communicating using a RAT operating in a high-frequency range (such as the millimeter-wave (mmW) frequency range), the applicable RF exposure parameter is PD, which can be adjusted to limit the heating of the UE and / or nearby surfaces. In some cases, a Maximum Permissible Exposure (MPE) limit (in the form of PD) may be imposed on wireless communication devices using transmission frequencies above 6 GHz. MPE limits are area-based exposure regulatory measures, such as energy density limits, which are defined as the number X (watts per square meter (W / m2)) of time-averaged values ​​over a frequency-dependent time window and averaged over a defined area to prevent human exposure hazards represented by tissue temperature changes. Since PD limits are generally used to assess RF exposure at transmission frequencies above 10 GHz, PD limits typically cover wireless communication technologies such as IEEE 802.11ad, 802.11ay, certain 5G bands (e.g., millimeter-wave bands), and other wireless communication technologies.

[0067] Additionally, different metrics can be used to assess RF exposure for different wireless communication technologies. UEs must generally meet all applicable RF exposure limits (e.g., SAR exposure limits or PD (e.g., MPE) exposure limits), which are typically regulatory requirements defined by aggregated exposure over a certain amount of time, often averaged within a mobility integration window (or mobility time window), sometimes referred to as a compliance window. For example, as in... Figure 3 As indicated by reference numeral 310 in the attached figure, the UE may be limited by an average power limit (P). limit (P) 限制This corresponds to the average power required to satisfy SAR exposure limits and / or MPE (e.g., PD) limits when the UE is to transmit substantially continuously over a mobile integration window of N seconds (e.g., 100 seconds). Accordingly, as indicated by reference numeral 320, the UE may use an instantaneous transmit power exceeding the average power limit for a period of time, as long as the average power over the mobile integration window is below the average power limit required to satisfy the MPE limit. For example, the UE may transmit at maximum transmit power at the beginning of the mobile integration window and then reduce the instantaneous transmit power until the end of the mobile integration window to ensure that the MPE limit for aggregation exposure is satisfied over the entire mobile integration window. Generally, as indicated by reference numeral 330, the UE may reduce the instantaneous transmit power to a reserve power level (P). 保留 (P reserve The reserved power level is the minimum transmit power level to maintain the link with the base station.

[0068] Wireless communication devices (e.g., UE 120) can use multiple wireless communication technologies to transmit signals simultaneously. For example, a wireless communication device can use a first wireless communication technology operating at 6 GHz or below (e.g., sub-6 GHz bands of 3G, 4G, 5G, etc.) and a second wireless communication technology operating above 6 GHz (e.g., 5G millimeter-wave bands in the 24 to 60 GHz band, IEEE 802.11ad, or 802.11ay) to transmit signals simultaneously. In some cases, a wireless communication device can use a first wireless communication technology (e.g., 3G, 4G, 5G, IEEE 802.11ac, etc. in the sub-6 GHz band) (where RF exposure is measured in the form of SAR) and a second wireless communication technology (e.g., 5G, IEEE 802.11ad, 802.11ay, etc. in the 24 to 60 GHz band) to transmit signals simultaneously (where RF exposure is measured in the form of PD). As an example, a UE may include multiple radios, modules, and / or antennas (collectively referred to herein as radios for convenience) corresponding to multiple RATs and / or frequency bands, which can be referred to as Figure 4 This is easier to understand. Because the UE is required to meet all applicable RF exposure parameters, the UE may be subject to both SAR and MPE restrictions, or it may be subject to different RF exposure parameters for different radio, module, or antenna bands, as described elsewhere in this document.

[0069] As indicated above, Figure 3 This is provided as an example. Other examples may differ from the one provided. Figure 3 The example described.

[0070] Figure 4 This is a diagram illustrating example 400 of biconnectivity according to this disclosure. Figure 4The example shown pertains to the Evolved Universal Mobile Telecommunications System Terrestrial Radio Access (E-UTRA)-NR Dual Connectivity (ENDC) mode. ENDC mode is sometimes referred to as NR or 5G Non-Autonomous (NSA) mode. ENDC mode is provided as an example of a scenario in which the UE can simultaneously implement multiple RAT technologies, and thus may require consideration of the RF exposure contribution of each RAT when meeting any applicable RF exposure compliance restrictions. However, the described ENDC mode is provided merely as an example of aspects that can be employed in this technology, and other dual connectivity modes and / or other multi-RAT communication technologies may be employed in other aspects without departing from the scope of this disclosure.

[0071] In ENDC mode, UE 120 communicates using the LTE RAT on the primary cell group (MCG) and the NR RAT on the secondary cell group (SCG). In some aspects, UE 120 may use dedicated radios, modules, and / or antennas (collectively referred to as radios for convenience) corresponding to various RATs for communication. For example, in ENDC mode, UE 120 may use a first radio to communicate via the LTE RAT and a second radio to communicate via the NR RAT. Furthermore, the aspects described herein are applicable to ENDC mode (e.g., where MCG is associated with an LTE RAT and SCG is associated with an NR RAT), NR-E-UTRA Dual Connectivity (NEDC) mode (e.g., where MCG is associated with an NR RAT and SCG is associated with an LTE RAT), NR Dual Connectivity (NRDC) mode (e.g., where MCG is associated with an NRRAT and SCG is also associated with an NR RAT), or another dual connectivity mode (e.g., where MCG is associated with a first RAT and SCG is associated with either a first RAT or a second RAT). Additionally, the aspects described herein can be applied to a mode in which UE 120 communicates via one or more additional communication technologies (such as Wi-Fi, Bluetooth, IEEE 802.11ad, 802.11ay, etc.) as an addition or replacement for using one or both of the LTE RAT and / or NR RAT. Therefore, as used herein, “dual connectivity mode” can refer to ENDC mode, NEDC mode, NRDC mode and / or another type of dual connectivity mode (e.g., communication using two or more connections via 2G, 3G, 4G, 4G LTE, 5G NR, 6G, Wi-Fi, Bluetooth, IEEE 802.11ad, 802.11ay, etc.).

[0072] Returning to the ENDC example, and as Figure 4As shown, UE 120 can communicate with both eNB (e.g., 4G base station 110) and gNB (e.g., 5G base station 110), and the eNB and gNB can communicate with the 4G / LTE core network (shown as including a Mobility Management Entity (MME), Packet Data Network Gateway (PGW), Serving Gateway (SGW), and / or other equipment, an Evolved Packet Core (EPC)) (e.g., directly or indirectly). Figure 4 In this context, PGW and SGW are collectively referred to as P / SGW. In some cases, eNB and gNB can be co-located at the same base station 110. In other cases, eNB and gNB can be included in different base stations 110 (e.g., they may not be co-located).

[0073] As in Figure 4 As further illustrated, in some aspects, a radio network permitting operation in 5G NSA mode can permit such operation by using an MCG for the first RAT (e.g., LTE RAT or 4G RAT) and an SCG for the second RAT (e.g., NR RAT or 5G RAT). In this scenario, the UE 120 can communicate with the eNB via the MCG and with the gNB via the SCG. In some aspects, the MCG can anchor the network connection between the UE 120 and the 4G / LTE core network (e.g., for mobility, coverage, and / or control plane information), and the SCG can be added as an additional carrier to increase throughput (e.g., for data traffic, and / or user plane information). In some aspects, the gNB and eNB may not transmit user plane information to each other. In some aspects, a UE 120 operating in dual connectivity mode may be concurrently connected to an LTE base station 110 (e.g., an eNB) and an NR base station 110 (e.g., a gNB) (e.g., in the case of ENDC or NEDC), or may be concurrently connected to one or more base stations 110 using the same RAT (e.g., in the case of NRDC). In some aspects, the MCG may be associated with a first frequency band (e.g., a sub-6 GHz band and / or the FR1 band), and the SCG may be associated with a second frequency band (e.g., a millimeter wave band and / or the FR2 band).

[0074] UE 120 may communicate via MCG and SCG using one or more radio bearers (e.g., data radio bearers (DRBs) and / or signaling radio bearers (SRBs)). For example, UE 120 may use one or more DRBs to transmit or receive data via the MCG and / or SCG. Similarly, UE 120 may use one or more SRBs to transmit or receive control information (e.g., radio resource control (RRC) information and / or measurement reports). In some aspects, radio bearers may be dedicated to a specific cell group (e.g., the radio bearer may be an MCG bearer or an SCG bearer). In some aspects, radio bearers may be split radio bearers. Split radio bearers may be split in the uplink and / or downlink. For example, a DRB may be split on the downlink (e.g., UE 120 may receive downlink information for the MCG or SCG in the DRB) but not on the uplink (e.g., the uplink may not be split from the main path to the MCG or SCG, so that UE 120 only transmits in the uplink on the main path). In some respects, the DRB can be split from the main path to the MCG or SCG on the uplink. A DRB split in the uplink can use the main path to transmit data until the size of the uplink transmission buffer meets the uplink data splitting threshold. If the uplink transmission buffer meets the uplink data splitting threshold, the UE 120 can use the DRB to transmit data to the MCG or SCG.

[0075] Again, despite Figure 4 Example 400 depicted illustrates the ENDC mode as an example of how UE 120 can utilize more than one radio and / or RAT, but this disclosure is not limited thereto, and in other respects, UE 120 may employ two or more radios, rather than a combination. Figure 4The described manner. For example, the UE may include multiple radios corresponding to multiple RATs and / or frequency bands. For example, the UE may be able to communicate using various RATs, such as 2G, 3G, 4G, 4G LTE, 5G NR, 6G, Wi-Fi, Bluetooth, IEEE 802.11ad, and / or 802.11ay. Additionally or alternatively, the UE may be able to communicate on various frequency bands within a RAT (e.g., FR1, FR2, FR3, FR4a, FR4-1, FR4, and / or FR5). For each RAT and / or frequency band, the UE may include a corresponding radio configured to communicate on that RAT and / or frequency band. Furthermore, in some cases, the UE may be configured to communicate concurrently using two or more radios. For example, the UE may communicate on 5G NR while simultaneously communicating via Bluetooth or a similar RAT. As another example, the UE may communicate using multiple component carriers, such as using a first radio via one or more component carriers and using a second radio via one or more other component carriers. In such instances, each individual radio can transmit communication using a certain level of allocated power, and the transmitting radios must collectively meet any applicable SAR exposure and / or MPE (e.g., PD) limits. Therefore, the techniques described herein provide power control for multiple communication links. Communication links can be associated with radios, RATs, dual-carrier (DC) mode connections, component carriers, combinations thereof, etc. For example, the techniques defined herein can provide power control for a first radio using a first RAT, a second radio using a second RAT, a third radio associated with a first component carrier of a given RAT, a fourth radio associated with a second component carrier of a given RAT, etc.

[0076] When a UE uses more than one radio for transmission, the SAR and / or MPE contributions from each radio must collectively remain within applicable SAR and / or MPE limits. Accordingly, for a given time frame or compliance window, the UE may allocate a portion of the total energy available for transmission (e.g., the total energy that the UE can utilize while remaining within applicable SAR and / or MPE limits) to each radio such that these radios collectively will not exceed the applicable SAR and / or MPE limits. In other words, for a given SAR exposure and PD limit (e.g., denoted as SAR...), lim (SAR 限制 ) and PD lim (PD 限制 Normalized SAR exposure and / or PD contribution for each radio (e.g., SAR exposure and / or PD contribution of a radio (expressed as SAR) i and / or PD i Divide by the applicable SAR exposure and / or PD limit (expressed as SAR)lim and / or PD lim The sum of all SAR exposure limits must be less than or equal to 1. Assuming that SAR exposure limits apply to radios operating in bands below 6 GHz, and MPE (e.g., PD) limits apply to radios operating in bands above 6 GHz, the applicable SAR exposure limits and / or PD limits can be summarized as follows:

[0077]

[0078] To maintain the UE's power output to meet the aforementioned conditions, the total transmission energy available to the UE for a given transmission time frame or compliance window is allocated among the radios so that if the radios transmit simultaneously, the common power output remains within applicable SAR exposure and / or MPE (e.g., PD) limits. However, allocating transmission energy in this manner can be inefficient because the transmission energy requirement for each radio varies over time and can thus vary within a transmission time frame or compliance window. Therefore, a radio allocated only a relatively small amount of energy may experience periods during a transmission time frame where it is not allocated enough energy to perform its scheduled transmissions. This is particularly problematic for radios attempting to transmit high-priority communications (such as, for example, control information), voice services (such as Voice over Internet Protocol (VoIP)), and video services (such as video telephony and / or video conferencing), where a shortage of transmission energy can lead to service interruptions or even link failures. Furthermore, a shortage of transmission energy may prevent some radios from transmitting low-priority, best-effort information, even if the transmission energy is available for that radio to do so, but that energy is assigned to another radio that does not need it at that time.

[0079] Conversely, radios allocated a relatively large amount of energy within a given time frame or compliance window may experience periods where they are not transmitting or transmitting a significant amount of additional information. Consequently, much of the transmission energy allocated to these radios may go unused. Furthermore, some radios may use their allocated transmission energy to transmit low-priority, best-effort information at the expense of other radios not being provided with sufficient transmission energy to transmit high-priority information (such as control information, VoIP, video conferencing information, or similar information). Additionally, determining the appropriate energy allocation for communication links can involve information determined by the transmitter and by the UE's Media Access Control (MAC) entity. If the MAC entity lacks information about the energy available for best-effort traffic transmission, it may be unable to efficiently manage best-effort traffic transmission, potentially leading to reduced throughput, increased latency, and suboptimal use of allocated energy.

[0080] As indicated above, Figure 4 This is provided as an example. Other examples may differ from the one provided. Figure 4 The example described.

[0081] Figures 5A-5E This is a diagram illustrating example 500 of a user device communicating with two subscriptions according to this disclosure. (See diagram for example.) Figure 3 As shown, the UE can communicate with a first base station, a second base station, and / or a third base station. The UE, the first base station, and the second base station may be part of a first wireless network (e.g., associated with a first subscription of the UE). The UE may use a first subscriber identity module (SIM) to communicate with the first base station and / or the second base station. In some aspects, the UE and the third base station may be part of a second wireless network (e.g., associated with a second subscription of the UE). The UE may use a second SIM to communicate with the third base station.

[0082] As in Figure 5A As shown by reference numeral 505 in the accompanying drawings, the UE and the first base station can establish a first connection on a first RAT, which is associated with a first subscription of the UE. For example, the UE and the first base station can use an LTE RAT to establish the first connection for communication via the UE's first SIM.

[0083] As shown by reference numeral 510, the UE and the second base station can establish a second connection via a second RAT, which is associated with a first subscription of the UE. For example, the UE and the second base station can use an NR RAT to establish the second connection for communication via the UE's first SIM. The first and second connections can be associated with the UE's dual connectivity mode. The first and second base stations can coexist. For example, a single base station can provide service via the first connection using the first RAT and via the second connection using the second RAT.

[0084] As shown by reference numeral 515 in the accompanying drawing, the UE and the third base station can establish a third connection over a third RAT, which is associated with a second subscription of the UE. For example, the UE and the third base station can use an LTE RAT to establish a second connection for communication via the UE's second SIM.

[0085] As in Figure 5BAs shown by reference numeral 520, the UE can communicate via a first connection (e.g., using a first RAT). As shown by reference numeral 525, the UE can communicate via a second connection (e.g., using a second RAT). The UE can use a first set of transmit power parameter values ​​to communicate via the first connection, and can use a second set of transmit power parameter values ​​to communicate via the second connection. The UE can be limited in transmit power at least in part based on time-averaged total radio frequency exposure (e.g., SAR parameters or MPE parameters, etc.). In other words, the transmit power via the second connection can be limited at least in part based on the transmit power via the first connection.

[0086] As by Figure 5C As indicated by reference numeral 530, the UE can tune away from the first connection and tune to a third connection. For example, the UE can tune away from the first connection and tune to the third connection at least in part based on a paging timing associated with the third connection. The UE can tune away from the first connection by configuring one or more components of the UE to communicate using frequencies (e.g., frequency bands or portions of frequency bandwidths) associated with the third connection rather than the first connection. When tuning away, the UE can communicate at least in part based on the one or more components being configured to communicate using frequencies associated with the third connection without receiving or transmitting via the first connection. As indicated by reference numeral 525, the UE can continue communicating via a second connection while tuning away from the first connection.

[0087] As shown by reference numeral 535, the UE can receive communications via a third connection. For example, the UE can receive paging via a third connection.

[0088] As indicated by reference numeral 540 in the accompanying drawing, the UE may fail to transmit via the first connection. For example, the UE may fail to transmit control information, one or more reference signals, or data communications. The UE may fail to transmit via the first connection at least in part because it has been tuned away from the first connection.

[0089] As in Figure 5D As shown by reference numeral 545 in the accompanying drawing, the UE can tune back to the first connection and tune away from the third connection. For example, after receiving or attempting to receive communication via the third connection, the UE can configure one or more components of the UE to communicate using the frequency associated with the first connection.

[0090] As indicated by reference numeral 550, the UE can receive transmit power control (TPC) commands via a first connection. The base station can transmit the TPC command at least in part based on the UE's failure to transmit when the UE is tuned away. For example, the base station can determine that the transmit power should be increased based at least in part on the base station's failure to receive communication from the UE that the base station expects to receive from the UE.

[0091] As in Figure 5E As shown by reference numeral 555 in the accompanying drawings, the UE can configure transmit power parameter values ​​for the first and second connections based at least in part on TPC commands and time averaging parameters. For example, the UE can apply TPC commands to increase the transmit power used for transmission via the first connection (e.g., transmit power parameter values). Based at least in part on increasing the transmit power used for the first connection, the UE may be required to reduce the transmit power used for transmission via the second connection based at least in part on time averaging parameters (such as SAR parameters or MPE parameters).

[0092] As indicated by reference numeral 560, the UE may use an increased transmit power parameter value (e.g., transmit power) to transmit communication via the first connection. For example, the UE may use excessive power to transmit communication.

[0093] As shown by reference numeral 565, the UE can transmit communication via a second connection using a reduced transmit power parameter value (e.g., transmit power). For example, the UE may use insufficient power to transmit communication.

[0094] Based at least in part on the UE configuring transmit power parameter values ​​for the first connection and the second connection based at least in part on the TPC command and time averaging parameters for the first connection, the UE may transmit communication via the second connection with insufficient power. Transmitting communication via the second connection with insufficient power may result in the second base station failing to receive the communication. Based at least in part on the second base station failing to receive the communication, the UE and the second base station may consume computing power, communication and / or network resources to detect and / or correct the failure, signal the TPC command to increase the power used for the second connection, and / or determine whether the power used for transmission via the first connection can be reduced to meet the time averaging parameters. For example, based at least in part on increasing the transmit power on the second connection, the UE may consume budgeted power for transmissions via the first connection and / or the third connection.

[0095] As indicated above, Figures 5A-5E This is provided as an example. Other examples may differ from the one provided. Figures 5A-5E The example described.

[0096] In some aspects described herein, a UE may establish a first connection in a first RAT, a second connection in a second RAT, and a third connection in a third RAT (which may be the same as the first RAT), wherein the first connection is associated with the UE's first subscription, the second connection is associated with the UE's first subscription, and the third connection is associated with the UE's second subscription. The UE may tune away from the first connection to attempt to receive communication via the third connection. When tuning away, the UE may fail to transmit communication via the first connection. After attempting to receive communication via the third connection, the UE may tune back to the first connection and may receive one or more TPC commands (e.g., to increase transmit power). The UE may configure the transmit power parameters of the first connection at least in part based on time averaging parameters. In some aspects, the time averaging parameters are associated with a maximum transmit power limit (MTPL).

[0097] In some aspects, the UE may configure the transmit power parameters of the first connection based at least in part on a limit value (e.g., an upper limit value) applied to an initial number of subframes, the limit value being at least in part based on the number of subframes during which the UE tunes away from the first connection. In some aspects, the UE may use path loss measurements before and after tuning away to determine the difference between the path loss measurements, and apply the MTPL at least in part based on the difference between the path loss measurements.

[0098] In some aspects, the UE can reduce the MTPL or a given upper limit of the MTPL for Physical Uplink Shared Channel (PUSCH) transmissions, and can not limit (e.g., within an initial number of subframes) the MTPL or not give an upper limit of the MTPL for Physical Uplink Control Channel (PUCCH) transmissions. In some aspects, the UE can apply TPC control as indicated by the associated base station to the PUCCH. In this way, the UE can improve the coverage of control channel communications, and at least in part based on the fact that control channel communications have a smaller power ratio than data channel communications, control channel communications will only have a slight impact on the time-averaged power budget.

[0099] MTPL indicates the amount of radiation, energy, or power that a wireless communication device is allowed to generate within a time window. In some aspects, a time window can be a limitation on the power (P) over any continuous period of time with a length defined by a time window length parameter. 限制 A scrolling window.

[0100] In some respects, the UE can apply technologies to comply with P 限制 Or other regulatory transmit power limits within a given window defined by a regulatory body or standard. The technique may include applying power to the transmission such that the average transmit power asymptotically approaches P within the given window. 限制Other regulatory transmit power limitations. In some respects, the UE may configure MTPL, etc., for connectivity, carrier, RAT, and / or subscriptions, at least in part, based on the amount of remaining power, which is at least in part based on P. 限制 And this is permissible. For example, power savings within a given subframe can be used to increase transmit power for subsequent transmissions. In this way, the UE can follow P... 限制 It can also improve transmission coverage (e.g., best-effort transmission).

[0101] Some of the techniques and apparatus described herein provide dynamic energy reservation for multiple communication links, such as multiple radios. Dynamic energy reservation provides sufficient transmit power to support high-priority and control traffic while maintaining SAR, MPE, or other applicable RF exposure metrics within applicable compliance limits. The UE can allocate an amount of energy to a communication link, which may include at least as much energy as the dynamic energy reservation for that link. The transmitter allocating the energy can report the remaining energy (after taking into account the dynamic energy reservation) to the UE's MAC entity, allowing the MAC entity to adjust the transmit data buffer state. In this way, the UE can ensure that high-priority traffic (such as control traffic and certain data communications) has sufficient energy for transmission. Furthermore, the MAC entity can selectively choke best-effort traffic, at least in part, based on the buffer state used for best-effort traffic after taking into account high-priority traffic. As a result, the UE allocates transmission energy resources more efficiently while remaining within applicable SAR exposure and / or MPE (e.g., PD) limits, leading to increased throughput, reduced latency, and more reliable service.

[0102] In some aspects, at least in part based on the UE determining that applying one or more TPC commands would require a reduction in the transmit power parameters of the second connection, the UE may ignore one or more TPC commands and / or may apply MTPL (e.g., a reduced MTPL) to the first connection. In some aspects, at least in part based on the UE determining that applying one or more TPC commands would not require a reduction in the transmit power parameters of the second connection (e.g., at least in part based on P... 限制 The UE may apply one or more TPC commands. In some aspects, the UE may ignore a configured number of TPC commands, may ignore TPC commands and / or apply MTPL to the first connection within a configured number of subframes, or may ignore TPC commands within a configured time period, etc. In some aspects, the UE may ignore TPC commands and / or apply MTPL to the first connection for data channel transmission only or for data channel transmission and control channel transmission, etc.

[0103] In some aspects, the UE may determine the configuration for the transmit power parameters (e.g., transmit power parameter values) based at least in part on the configuration used for the first connection prior to tuning out of the first connection. In some aspects, the UE may determine the configuration of the transmit power parameters to be modified for the first connection prior to tuning out of the first connection based at least in part on open-loop measurements (e.g., RSRP and / or PL RS measurements).

[0104] By configuring the transmit power parameters of the first connection at least in part based on the UE's time-averaged parameters, the UE can reduce the likelihood of transmitting communication via the second connection with insufficient power. In this way, the UE and the second base station can save computational resources, communication resources, and / or network resources that would otherwise be used to detect and / or correct communication failures of the second base station, to signal TPC commands to increase the power used for the second connection, and / or to determine whether the power used for transmission via the first connection can be reduced to meet the time-averaged parameters.

[0105] Figure 6 This is a diagram illustrating example 600, which relates to configuring transmit power parameters after tuning back to subscription in dual-connection mode, according to this disclosure. (See diagram for example 60 ... Figure 6 As shown, the UE (e.g., UE 120) can communicate with one or more base stations (e.g., base station 110) that have a first subscription and with one or more base stations (e.g., base station 110) that have a second subscription. In some aspects, the UE and the one or more base stations that have a first subscription can be part of a first wireless network (e.g., wireless network 100), and the UE and the one or more base stations that have a second subscription can be part of a second wireless network (e.g., wireless network 100).

[0106] As shown by reference numeral 605, the UE can establish a first connection and a second connection associated with its first subscription. For example, the UE can establish a first connection for a first RAT associated with its first subscription, and can establish a second connection for a second RAT associated with its first subscription. In some aspects, the UE can establish the first and second connections as part of a dual connectivity mode (e.g., ENDC mode) connection associated with its first subscription.

[0107] In some respects, the first base station and the second base station can be located in the same place. For example, a single base station of one or more base stations may provide services using a first RAT via a first connection and may provide services using a second RAT via a second connection.

[0108] In some respects, the UE can communicate simultaneously via both the first connection and the second connection. For example, the UE can adjust a first set of components for communication via the first connection and can tune a second set of components for communication via the second connection.

[0109] As indicated by reference numeral 610 in the accompanying drawing, the UE can establish a third connection associated with its second subscription. In some aspects, the UE can communicate via both the first and third connections using the same set of components. In this way, the UE may not be able to communicate via the third connection without tuning out of the first connection.

[0110] As indicated by reference numeral 615, the UE can communicate via a first connection and a second connection. The UE can configure transmit power parameters for the first connection based at least in part on one or more TPC commands received from a base station associated with the first connection from one or more base stations in the first subscription. Similarly, the UE can configure transmit power parameters for the second connection based at least in part on one or more TPC commands received from a base station associated with the second connection from one or more base stations in the first subscription. The UE can further configure transmit power parameters for both the first and second connections based at least in part on time-averaged parameters (e.g., SAR or MPE, etc.).

[0111] As indicated by reference numeral 620, the UE may determine PL RS measurements and / or RSRP associated with the first connection and / or the second connection. In some aspects, the UE may measure the PL RS and / or RSRP for the first connection based at least in part on determining that the UE will tune out of the first connection to attempt to receive communication via a third connection. In some aspects, the UE may store the measurements of PL RS and / or RSRP based at least in part on the UE tuning out of the first connection.

[0112] As indicated by reference numeral 625, the UE can tune away from the first connection. For example, the UE can tune away from the first connection to receive communication via a third connection. The UE can configure one or more components of the UE to communicate via a frequency (e.g., a frequency band or bandwidth portion, etc.) to communicate via the third connection. The UE is unable to communicate via the first connection, at least in part, based on the fact that the UE is tuned away from the first connection.

[0113] As indicated by reference numeral 630 in the accompanying drawing, the UE can receive communications via a third connection. For example, the UE can receive paging, one or more reference signals, or synchronization signal blocks, etc.

[0114] As indicated by reference numeral 635, the UE can tune back to the first connection. For example, the UE can be configured to communicate via a frequency, in order to communicate via the first connection. Based at least in part on the UE tuning back to the first connection, the UE is able to communicate via the first connection and may be unable to communicate via the third connection.

[0115] As indicated by reference numeral 640, the UE may receive one or more TPC commands and / or reference signals associated with the first subscription from one or more base stations in the first subscription. In some aspects, the UE may receive one or more TPC commands at least in part based on the UE's failure to transmit and the base station's failure to receive one or more communications expected from the UE.

[0116] In some respects, the UE may determine whether to apply (e.g., use) one or more TPC commands based at least in part on a determination that applying one or more transmit power control commands would impose a limitation on transmit power parameters used for transmission via the second connection. For example, the UE may determine whether to ignore one or more TPC commands based at least in part on a determination that applying one or more transmit power control commands would impose a limitation on transmit power parameters used for transmission via the second connection.

[0117] As indicated by reference numeral 645, the UE may determine the PLRS measurement and / or RSRP for the first connection after tuning back to the first connection. In some aspects, the UE may determine the difference between the PL RS measurement and / or RSRP before tuning away from the first connection and the PL RS measurement and / or RSRP after tuning away from the first connection.

[0118] In some aspects, the UE may determine the transmit power parameter to be modified before tuning departure based at least in part on the difference. In some aspects, the UE may determine the value of the transmit power parameter to be modified based at least in part on the difference between the first PL RS and the second PL RS satisfying a PL RS change threshold and / or at least in part on the difference between the first RSRP and the second RSRP satisfying an RSRP change threshold. In some aspects, modifying one of these values ​​may be based at least in part on the difference between the first PL RS and the second PL RS and / or at least in part on the difference between the first RSRP and the second RSRP.

[0119] As indicated by reference numeral 650 in the accompanying drawing, the UE can configure the transmit power parameters for the first connection. In some aspects, the UE can configure the transmit power parameters for the first connection based at least in part on time-averaged parameters. For example, the UE can configure the transmit power parameters at least in part based on MTPL, SAR parameters, or MPE parameters that limit the total transmit power used for the first and second connections. The UE can configure the transmit power parameters for the first connection at least in part based on whether the application of one or more TPC commands and SAR or MPE parameters requires a reduction in the transmit power parameters for the second connection.

[0120] In some respects, the UE may determine to ignore one or more TPC commands received for the first connection. The UE may determine to ignore a configured number of TPC commands (e.g., 3 TPC commands) after tuning back to the first connection, to ignore TPC commands within a configured number of subframes after tuning back to the first connection, and / or to ignore TPC commands within a configured amount of time after tuning back to the first connection.

[0121] In some aspects, the UE may determine the transmit power after tuning back to the first connection, wherein the transmit power is at least partially based on the MTPL. The MTPL may be at least partially based on the transmit power configured (e.g., in use) before tuning away from the first connection. The MTPL may be configured for several subframes after tuning back to the first connection and / or a configured amount of time after tuning back to the first connection, etc. In some aspects, the UE may determine the transmit power to be configured based at least partially on determining the PL RS measurement and / or RSRP (as described in conjunction with reference to reference numeral 645).

[0122] In some aspects, the UE may configure the transmit power parameters of the first connection at least in part based on a configuration that restores to the transmit power parameters used for the first connection before tuning out of the first connection. In some aspects, the UE may determine, at least in part, to modify the configuration of the transmit power parameters used for the first connection before tuning out of the first connection based on changes in PL RS measurements and / or RSRP measurements, as described herein.

[0123] In some aspects, the UE may configure transmit power parameters for transmission via the data channel of the first connection at least partially based on ignoring one or more transmit power control commands received for the first connection after tuning back to the first connection, or at least partially based on configuring the MTPL, and at least partially based on the transmit power parameters used before tuning away from the first connection. In some aspects, the UE may configure transmit power parameters for transmission via the control channel of the first connection at least partially based on applying one or more transmit power control commands received for the first connection after tuning back to the first connection. Alternatively, the UE may configure transmit power parameters for transmission via both the data channel and control channel of the first connection at least partially based on ignoring one or more transmit power control commands received for the first connection after tuning back to the first connection.

[0124] By configuring the transmit power parameters of the first connection based at least in part on the time-averaged parameters, the transmit power parameters before tuning away, and / or the determination of whether to ignore TPC commands, the UE can reduce the likelihood of transmitting communication via the second connection with insufficient power. In this way, the UE and the second base station can save computational resources, communication resources, and / or network resources that would otherwise be used to detect and / or correct communication failures of the second base station, signal TPC commands to increase power for the second connection, and / or determine whether power for transmission via the first connection can be reduced to meet the time-averaged parameters.
