Description:
CROSS REFERENCE TO RELATED APPLICATION(S) 
     This application claims the benefit of Patent Cooperation Treaty International Application Serial No. PCT/CN2019/116785, entitled “METHODS AND APPARATUS TO FACILITATE DUAL CONNECTIVITY POWER CONTROL MODE” and filed on Nov. 8, 2019, of which is expressly incorporated by reference herein in its entirety. 
    
    
     BACKGROUND 
     Technical Field 
     The present disclosure relates generally to communication systems, and more particularly, to power control modes. 
     Introduction 
     Wireless communication systems are widely deployed to provide various telecommunication services such as telephony, video, data, messaging, and broadcasts. Typical wireless communication systems may employ multiple-access technologies capable of supporting communication with multiple users by sharing available system resources. 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, and time division synchronous code division multiple access (TD-SCDMA) systems. 
     These multiple access technologies have been adopted in various telecommunication standards to provide a common protocol that enables different wireless devices to communicate on a municipal, national, regional, and even global level. An example telecommunication standard is 5G New Radio (NR). 5G/NR is part of a continuous mobile broadband evolution promulgated by Third Generation Partnership Project (3GPP) to meet new requirements associated with latency, reliability, security, scalability (e.g., with Internet of Things (IoT)), and other requirements. 5G/NR includes services associated with enhanced mobile broadband (eMBB), massive machine type communications (mMTC), and ultra reliable low latency communications (URLLC). Some aspects of 5G/NR may be based on the 4G Long Term Evolution (LTE) standard. There exists a need for further improvements in 5G/NR technology. These improvements may also be applicable to other multi-access technologies and the telecommunication standards that employ these technologies. 
     SUMMARY 
     The following presents a simplified summary of one or more aspects in order to provide a basic understanding of such aspects. This summary is not an extensive overview of all contemplated aspects, and is intended to neither identify key or critical elements of all aspects nor delineate the scope of any or all aspects. Its sole purpose is to present some concepts of one or more aspects in a simplified form as a prelude to the more detailed description that is presented later. 
     In some examples, a wireless device (e.g., a user equipment (UE)) may be connected to more than one network entity at a time. For example, a UE configured for dual connectivity may be connected to two different base stations, and each base station may include a cell group. In some such examples, each cell group may include one or more serving cells (sometimes referred to as “carriers”). A master cell group (MCG) is a cell group that includes at least a primary serving cell and may also include one or more secondary serving cells (e.g., the MCG may include a primary serving cell and zero or more secondary serving cell). A secondary cell group (SCG) is a cell group that includes one or more additional serving cells. 
     In some examples, for each cell group, the UE may include one or more carriers for transmitting data and/or control information from the UE to the respective cell group. In some such examples, the one or more carriers for each cell group may operate with respective transmit powers. For example, the UE may transmit an uplink transmission to the MCG using an MCG transmit power and the UE may transmit an uplink transmission to the SCG using an SCG transmit power. 
     Example techniques disclosed herein facilitate power control sharing for uplink transmissions for a UE that is connected to two cell groups (e.g., an MCG and an SCG) and that is connected to at least one cell group using at least one carrier located in a first frequency range (FR 1 ) and at least one carrier located in a second frequency range (FR 2 ). For example, in a first example scenario, the UE may be connected to the MCG using one or more carriers in FR 1  and one or more carriers in FR 2  and may also be connected to the SCG using one or more carriers in FR 1  and one or more carriers in FR 2 . In a second example scenario, the UE may be connected to the MCG using one or more carriers in a frequency range (e.g., in FR 1  or in FR 2 ) and may also be connected to the SCG using one or more carriers in FR 1  and one or more carriers in FR 2 . In a third example scenario, the UE may be connected to the MCG using one or more carriers in FR 1  and one or more carriers in FR 2  and may also be connected to the SCG using one or more carriers in a frequency range (e.g., in FR 1  or in FR 2 ). Thus, it should be appreciated that in some examples, the MCG carriers and the SCG carriers may overlap for at least one of the frequency ranges (e.g., in the second and third example scenarios) or may overlap for both frequency ranges (e.g., in the first example scenario). 
     In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. An example apparatus for wireless communication of a wireless device at a UE connects to an MCG on a first set of MCG serving cells within a first frequency range (FR 1 ) and a second set of MCG serving cells within a second frequency range (FR 2 ), and connecting to an SCG on a first set of SCG serving cells within the FR 1  and a second set of SCG bands within the FR 2 . The example apparatus also receives a transmit power configuration including an FR 1  power control mode and an FR 2  power control mode. The example apparatus also transmits to at least one of the MCG serving cells or the SCG serving cells in FR 1  and FR 2  with a transmit power determined based on the respective transmit power configuration. For example, the apparatus may transmit in FR 1  with a transmit power determined based on the FR 1  power control mode and may transmit in FR 2  with a transmit power determined based on the FR 2  power control mode. It should be appreciated that in some examples, the FR 1  power control mode may be the same as the FR 2  power control mode, and that in other examples, the FR 1  power control mode may be different than the FR 2  power control mode. 
     In another aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. An example apparatus for wireless communication of a wireless device at a UE connects to an MCG on a first set of MCG serving cells within one of a first frequency range (FR 1 ) or a second frequency range (FR 2 ), and connecting to an SCG on a first set of SCG serving cells within the FR 1  and a second set of SCG serving cells within the FR 2 . The example apparatus also receives a transmit power configuration for a power control mode for FR 1  when the first set of MCG serving cells is within FR 1  and for FR 2  when the first set of MCG serving cells is within FR 2 . The example apparatus also transmits to at least one of the MCG serving cells or the SCG serving cells in FR 1  when the first set of MCG serving cells is within FR 1  with a transmit power determined based on the transmit power configuration, or in FR 2  when the first set of MCG serving cells is within FR 2  with a transmit power determined based on the transmit power configuration. 
     In another aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. An example apparatus for wireless communication of a wireless device at a UE connects to an SCG on a first set of SCG serving cells within one of a first frequency range (FR 1 ) or a second frequency range (FR 2 ), and connecting to an MCG on a first set of MCG serving cells within the FR 1  and a second set of MCG serving cells within the FR 2 . The example apparatus also receives a transmit power configuration for a power control mode for FR 1  when the first set of SCG serving cells is within FR 1  and for FR 2  when the first set of SCG serving cells is within FR 2 . The example apparatus also transmits to at least one of the MCG serving cells or the SCG serving cells with a transmit power determined based on the transmit power configuration. 
     To the accomplishment of the foregoing and related ends, the one or more aspects comprise the features hereinafter fully described and particularly pointed out in the claims. The following description and the annexed drawings set forth in detail certain illustrative features of the one or more aspects. These features are indicative, however, of but a few of the various ways in which the principles of various aspects may be employed, and this description is intended to include all such aspects and their equivalents.

     DETAILED DESCRIPTION 
     The detailed description set forth below in connection with the appended drawings is intended as a description of various configurations and is not intended to represent the only configurations in which the concepts described herein may be practiced. The detailed description includes specific details for the purpose of providing a thorough understanding of various concepts. However, it will be apparent to those skilled in the art that these concepts may be practiced without these specific details. In some instances, well known structures and components are shown in block diagram form in order to avoid obscuring such concepts. 
     Several aspects of telecommunication systems will now be presented with reference to various apparatus and methods. These apparatus and methods will be described in the following detailed description and illustrated in the accompanying drawings by various blocks, components, circuits, processes, algorithms, etc. (collectively referred to as “elements”). These elements may be implemented using electronic hardware, computer software, or any combination thereof. Whether such elements are implemented as hardware or software depends upon the particular application and design constraints imposed on the overall system. 
     By way of example, an element, or any portion of an element, or any combination of elements may be implemented as a “processing system” that includes one or more processors. Examples of processors include microprocessors, microcontrollers, graphics processing units (GPUs), central processing units (CPUs), application processors, digital signal processors (DSPs), reduced instruction set computing (RISC) processors, systems on a chip (SoC), baseband processors, field programmable gate arrays (FPGAs), programmable logic devices (PLDs), state machines, gated logic, discrete hardware circuits, and other suitable hardware configured to perform the various functionality described throughout this disclosure. One or more processors in the processing system may execute software. Software shall be construed broadly to mean instructions, instruction sets, code, code segments, program code, programs, subprograms, software components, applications, software applications, software packages, routines, subroutines, objects, executables, threads of execution, procedures, functions, etc., whether referred to as software, firmware, middleware, microcode, hardware description language, or otherwise. 
     Accordingly, in one or more example embodiments, the functions described may be implemented in hardware, software, or any combination thereof. If implemented in software, the functions may be stored on or encoded as one or more instructions or code on a computer-readable medium. Computer-readable media includes computer storage media. Storage media may be any available media that can be accessed by a computer. By way of example, and not limitation, such computer-readable media can comprise a random-access memory (RAM), a read-only memory (ROM), an electrically erasable programmable ROM (EEPROM), optical disk storage, magnetic disk storage, other magnetic storage devices, combinations of the aforementioned types of computer-readable media, or any other medium that can be used to store computer executable code in the form of instructions or data structures that can be accessed by a computer. 
     As used herein, the term computer-readable medium is expressly defined to include any type of computer readable storage device and/or storage disk and to exclude propagating signals and to exclude transmission media. As used herein, “computer-readable medium,” “machine-readable medium,” “computer-readable memory,” and “machine-readable memory” are used interchangeably. 
       FIG.  1    is a diagram illustrating an example of a wireless communications system and an access network  100 . The wireless communications system (also referred to as a wireless wide area network (WWAN)) includes base stations  102 , UEs  104 , an Evolved Packet Core (EPC)  160 , and another core network  190  (e.g., a 5G Core (5GC)). The base stations  102  may include macrocells (high power cellular base station) and/or small cells (low power cellular base station). The macrocells include base stations. The small cells include femtocells, picocells, and microcells. 
     The base stations  102  configured for 4G LTE (collectively referred to as Evolved Universal Mobile Telecommunications System (UMTS) Terrestrial Radio Access Network (E-UTRAN)) may interface with the EPC  160  through backhaul links  132  (e.g., S1 interface). The base stations  102  configured for 5G/NR (collectively referred to as Next Generation RAN (NG-RAN)) may interface with core network  190  through backhaul links  184 . In addition to other functions, the base stations  102  may perform one or more of the following functions: transfer of user data, radio channel ciphering and deciphering, integrity protection, header compression, mobility control functions (e.g., handover, dual connectivity), inter-cell interference coordination, connection setup and release, load balancing, distribution for non-access stratum (NAS) messages, NAS node selection, synchronization, radio access network (RAN) sharing, multimedia broadcast multicast service (MBMS), subscriber and equipment trace, RAN information management (RIM), paging, positioning, and delivery of warning messages. The base stations  102  may communicate directly or indirectly (e.g., through the EPC  160  or core network  190 ) with each other over backhaul links  134  (e.g., X 2  interface). The backhaul links  134  may be wired or wireless. 
     The base stations  102  may wirelessly communicate with the UEs  104 . Each of the base stations  102  may provide communication coverage for a respective geographic coverage area  110 . There may be overlapping geographic coverage areas  110 . For example, the small cell  102 ′ may have a coverage area  110 ′ that overlaps the coverage area  110  of one or more macro base stations  102 . A network that includes both small cell and macrocells may be known as a heterogeneous network. A heterogeneous network may also include Home Evolved Node Bs (eNBs) (HeNBs), which may provide service to a restricted group known as a closed subscriber group (CSG). The communication links  120  between the base stations  102  and the UEs  104  may include uplink (UL) (also referred to as reverse link) transmissions from a UE  104  to a base station  102  and/or downlink (DL) (also referred to as forward link) transmissions from a base station  102  to a UE  104 . The communication links  120  may use multiple-input and multiple-output (MIMO) antenna technology, including spatial multiplexing, beamforming, and/or transmit diversity. The communication links may be through one or more carriers. The base stations  102  / UEs  104  may use spectrum up to Y MHz (e.g., 5, 10, 15, 20, 100, 400, etc. MHz) bandwidth per carrier allocated in a carrier aggregation of up to a total of Yx MHz (x component carriers) used for transmission in each direction. The carriers may or may not be adjacent to each other. Allocation of carriers may be asymmetric with respect to DL and UL (e.g., more or fewer carriers may be allocated for DL than for UL). The component carriers may include a primary component carrier and one or more secondary component carriers. A primary component carrier may be referred to as a primary cell (PCell) and a secondary component carrier may be referred to as a secondary cell (SCell). 
     Certain UEs  104  may communicate with each other using device-to-device (D2D) communication link  158 . The D2D communication link  158  may use the DL/UL WWAN spectrum. The D2D communication link  158  may use one or more sidelink channels, such as a physical sidelink broadcast channel (PSBCH), a physical sidelink discovery channel (PSDCH), a physical sidelink shared channel (PSSCH), and a physical sidelink control channel (PSCCH). D2D communication may be through a variety of wireless D2D communications systems, such as for example, FlashLinQ, WiMedia, Bluetooth, ZigBee, Wi-Fi based on the IEEE 802.11 standard, LTE, or NR. 
     The wireless communications system may further include a Wi-Fi access point (AP)  150  in communication with Wi-Fi stations (STAs)  152  via communication links  154   in a 5 GHz unlicensed frequency spectrum. When communicating in an unlicensed frequency spectrum, the STAs  152  / AP  150  may perform a clear channel assessment (CCA) prior to communicating in order to determine whether the channel is available. 
     The small cell  102 ′ may operate in a licensed and/or an unlicensed frequency spectrum. When operating in an unlicensed frequency spectrum, the small cell  102 ′ may employ NR and use the same 5 GHz unlicensed frequency spectrum as used by the Wi-Fi AP  150 . The small cell  102 ′, employing NR in an unlicensed frequency spectrum, may boost coverage to and/or increase capacity of the access network. 
     A base station  102 , whether a small cell  102 ′ or a large cell (e.g., macro base station), may include an eNB, gNodeB (gNB), or another type of base station. Some base stations, such as gNB  180  may operate in a traditional sub 6 GHz spectrum, in millimeter wave (mmW) frequencies, and/or near mmW frequencies in communication with the UE  104 . When the gNB  180  operates in mmW or near mmW frequencies, the gNB  180  may be referred to as an mmW base station. Extremely high frequency (EHF) is part of the RF in the electromagnetic spectrum. EHF has a range of 30 GHz to 300 GHz and a wavelength between 1 millimeter and 10 millimeters. Radio waves in the band may be referred to as a millimeter wave. Near mmW may extend down to a frequency of 3 GHz with a wavelength of 100 millimeters. The super high frequency (SHF) band extends between 3 GHz and 30 GHz, also referred to as centimeter wave. Communications using the mmW / near mmW radio frequency band (e.g., 3 GHz - 300 GHz) has extremely high path loss and a short range. The mmW base station  180  may utilize beamforming  182  with the UE  104  to compensate for the extremely high path loss and short range. 
     The base station  180  may transmit a beamformed signal to the UE  104  in one or more transmit directions  182 ′. The UE  104  may receive the beamformed signal from the base station  180  in one or more receive directions  182 ″. The UE  104  may also transmit a beamformed signal to the base station  180  in one or more transmit directions. The base station  180  may receive the beamformed signal from the UE  104  in one or more receive directions. The base station  180  / UE  104  may perform beam training to determine the best receive and transmit directions for each of the base station  180  / UE  104 . The transmit and receive directions for the base station  180  may or may not be the same. The transmit and receive directions for the UE  104  may or may not be the same. 
     The EPC  160  may include a Mobility Management Entity (MME)  162 , other MMEs  164 , a Serving Gateway  166 , a Multimedia Broadcast Multicast Service (MBMS) Gateway  168 , a Broadcast Multicast Service Center (BM-SC)  170 , and a Packet Data Network (PDN) Gateway  172 . The MME  162  may be in communication with a Home Subscriber Server (HSS)  174 . The MME  162  is the control node that processes the signaling between the UEs  104  and the EPC  160 . Generally, the MME  162  provides bearer and connection management. All user Internet protocol (IP) packets are transferred through the Serving Gateway  166 , which itself is connected to the PDN Gateway  172 . The PDN Gateway  172  provides UE IP address allocation as well as other functions. The PDN Gateway  172  and the BM-SC  170  are connected to the IP Services  176 . The IP Services  176  may include the Internet, an intranet, an IP Multimedia Subsystem (IMS), a PS Streaming Service, and/or other IP services. The BM-SC  170  may provide functions for MBMS user service provisioning and delivery. The BM-SC  170  may serve as an entry point for content provider MBMS transmission, may be used to authorize and initiate MBMS Bearer Services within a public land mobile network (PLMN), and may be used to schedule MBMS transmissions. The MBMS Gateway  168  may be used to distribute MBMS traffic to the base stations  102  belonging to a Multicast Broadcast Single Frequency Network (MBSFN) area broadcasting a particular service, and may be responsible for session management (start/stop) and for collecting eMBMS related charging information. 
     The core network  190  may include a Access and Mobility Management Function (AMF)  192 , other AMFs  193 , a Session Management Function (SMF)  194 , and a User Plane Function (UPF)  195 . The AMF  192  may be in communication with a Unified Data Management (UDM)  196 . The AMF  192  is the control node that processes the signaling between the UEs  104  and the core network  190 . Generally, the AMF  192  provides QoS flow and session management. All user Internet protocol (IP) packets are transferred through the UPF  195 . The UPF  195  provides UE IP address allocation as well as other functions. The UPF  195  is connected to the IP Services  197 . The IP Services  197  may include the Internet, an intranet, an IP Multimedia Subsystem (IMS), a PS Streaming Service, and/or other IP services. 
     The base station may also be referred to as a gNB, Node B, evolved Node B (eNB), an access point, a base transceiver station, a radio base station, a radio transceiver, a transceiver function, a basic service set (BSS), an extended service set (ESS), a transmit reception point (TRP), or some other suitable terminology. The base station  102  provides an access point to the EPC  160  or core network  190  for a UE  104 . Examples of UEs  104  include a cellular phone, a smart phone, a session initiation protocol (SIP) phone, a laptop, a personal digital assistant (PDA), a satellite radio, a global positioning system, a multimedia device, a video device, a digital audio player (e.g., MP3 player), a camera, a game console, a tablet, a smart device, a wearable device, a vehicle, an electric meter, a gas pump, a large or small kitchen appliance, a healthcare device, an implant, a sensor/actuator, a display, or any other similar functioning device. Some of the UEs  104  may be referred to as IoT devices (e.g., parking meter, gas pump, toaster, vehicles, heart monitor, etc.). The UE  104  may also be referred to as a station, a mobile station, a subscriber station, a mobile unit, a subscriber unit, a wireless unit, a remote unit, a mobile device, a wireless device, a wireless communications device, a remote device, a mobile subscriber station, an access terminal, a mobile terminal, a wireless terminal, a remote terminal, a handset, a user agent, a mobile client, a client, or some other suitable terminology. 
     Referring again to  FIG.  1   , in certain aspects, the UE  104  may be configured to manage one or more aspects of wireless communication via power control sharing for cell groups with serving cells (or carriers) located within different frequency ranges. As an example, in  FIG.  1   , the UE  104  may include a UE power control handling component  198  configured to connect to an MCG on a first set of MCG serving cells (or carriers) within a first frequency range (FR 1 ) and a second set of MCG serving cells within a second frequency range (FR 2 ), and to connect to a secondary cell group (SCG) on a first set of SCG serving cells within the FR 1  and a second set of SCG bands within the FR 2 . For example, the FR 1  band may include a sub-6 gigahertz (GHz) frequency band and the FR 2  band may include a millimeter wave (mmW) frequency band. The example UE power control handling component  198  may also be configured to receive a transmit power configuration for power control mode for both FR 1  and FR 2 . The example UE power control handling component  198  may also be configured to transmit to at least one of the MCG serving cells or the SCG serving cells with a transmit power determined based on the transmit power configuration. 
     In some examples, the UE power control handling component  198  may be configured to connect to an MCG on a first set of MCG serving cells within one of a first frequency range (FR 1 ) or a second frequency range (FR 2 ), and to connect to an SCG on a first set of SCG serving cells within the FR 1  and a second set of SCG serving cells within the FR 2 . The example UE power control handling component  198  may also be configured to receive a transmit power configuration for a power control mode for FR 1  when the first set of MCG serving cells is within FR 1  and for FR 2  when the first set of MCG serving cells is within FR 2 . The example UE power control handling component  198  may also be configured to transmit to at least one of the MCG serving cells or the SCG serving cells with a transmit power determined based on the transmit power configuration. 
     In some examples, the UE power control handling component  198  may be configured to connect to an SCG on a first set of SCG serving cells within one of a first frequency range (FR 1 ) or a second frequency range (FR 2 ), and to connect to an MCG on a first set of MCG serving cells within the FR 1  and a second set of MCG serving cells within the FR 2 . The example UE power control handling component  198  may also be configured to receive a transmit power configuration for a power control mode for FR 1  when the first set of SCG serving cells is within FR 1  and for FR 2  when the first set of SCG serving cells is within FR 2 . The example UE power control handling component  198  may also be configured to transmit to at least one of the MCG serving cells or the SCG serving cells with a transmit power determined based on the transmit power configuration. 
     Although the following description may provide examples based on 5G/NR, it should be appreciated that the concepts described herein may be applicable to other communication technologies. For example, the concepts described herein may be applicable to LTE, LTE-A, CDMA, GSM, and/or other wireless technologies (or RATs) in which a UE is configured for dual connectivity with a first cell group and a second cell group and includes at least one carrier within a first frequency range and at least one carrier within a second frequency range for at least one of the cell groups. 
       FIG.  2 A  is a diagram  200  illustrating an example of a first subframe within a 5G/NR frame structure.  FIG.  2 B  is a diagram  230  illustrating an example of DL channels within a 5G/NR subframe.  FIG.  2 C  is a diagram  250  illustrating an example of a second subframe within a 5G/NR frame structure.  FIG.  2 D  is a diagram  280  illustrating an example of UL channels within a 5G/NR subframe. The 5G/NR frame structure may be FDD in which for a particular set of subcarriers (carrier system bandwidth), subframes within the set of subcarriers are dedicated for either DL or UL, or may be TDD in which for a particular set of subcarriers (carrier system bandwidth), subframes within the set of subcarriers are dedicated for both DL and UL. In the examples provided by  FIGS.  2 A,  2 C , the 5G/NR frame structure is assumed to be TDD, with subframe 4 being configured with slot format 28 (with mostly DL), where D is DL, U is UL, and X is flexible for use between DL/UL, and subframe 3 being configured with slot format 34 (with mostly UL). While subframes 3, 4 are shown with slot formats 34,28, respectively, any particular subframe may be configured with any of the various available slot formats 0-61. Slot formats 0, 1 are all DL, UL, respectively. Other slot formats 2-61 include a mix of DL, UL, and flexible symbols. UEs are configured with the slot format (dynamically through DL control information (DCI), or semi-statically/statically through radio resource control (RRC) signaling) through a received slot format indicator (SFI). Note that the description infra applies also to a 5G/NR frame structure that is TDD. 
     Other wireless communication technologies may have a different frame structure and/or different channels. A frame (10 ms) may be divided into 10 equally sized subframes (1 ms). Each subframe may include one or more time slots. Subframes may also include mini-slots, which may include 7, 4, or 2 symbols. Each slot may include 7 or 14 symbols, depending on the slot configuration. For slot configuration 0, each slot may include 14 symbols, and for slot configuration 1, each slot may include 7 symbols. The symbols on DL may be cyclic prefix (CP) OFDM (CP-OFDM) symbols. The symbols on UL may be CP-OFDM symbols (for high throughput scenarios) or discrete Fourier transform (DFT) spread OFDM (DFT-s-OFDM) symbols (also referred to as single carrier frequency-division multiple access (SC-FDMA) symbols) (for power limited scenarios; limited to a single stream transmission). The number of slots within a subframe is based on the slot configuration and the numerology. For slot configuration 0, different numerologies µ 0 to 5 allow for 1, 2, 4, 8, 16, and 32 slots, respectively, per subframe. For slot configuration 1, different numerologies 0 to 2 allow for 2, 4, and 8 slots, respectively, per subframe. Accordingly, for slot configuration 0 and numerology µ, there are 14 symbols/slot and 2µ slots/subframe. The subcarrier spacing and symbol length/duration are a function of the numerology. The subcarrier spacing may be equal to 2 µ  * 15 kHz, where µ is the numerology 0 to 5. As such, the numerology µ=0 has a subcarrier spacing of 15 kHz and the numerology µ=5 has a subcarrier spacing of 480 kHz. The symbol length/duration is inversely related to the subcarrier spacing.  FIGS.  2 A to  2 D  provide an example of slot configuration 0 with 14 symbols per slot and numerology µ=0 with 1 slot per subframe. The subcarrier spacing is 15 kHz and symbol duration is approximately 66.7 µs. 
     A resource grid may be used to represent the frame structure. Each time slot includes a resource block (RB) (also referred to as physical RBs (PRBs)) that extends 12 consecutive subcarriers. The resource grid is divided into multiple resource elements (REs). The number of bits carried by each RE depends on the modulation scheme. 
     As illustrated in  FIG.  2 A , some of the REs carry reference (pilot) signals (RS) for the UE. The RS may include demodulation RS (DM-RS) (indicated as Rx for one particular configuration, where 100x is the port number, but other DM-RS configurations are possible) and channel state information reference signals (CSI-RS) for channel estimation at the UE. The RS may also include beam measurement RS (BRS), beam refinement RS (BRRS), and phase tracking RS (PT-RS). 
       FIG.  2 B  illustrates an example of various DL channels within a subframe of a frame. The physical downlink control channel (PDCCH) carries DCI within one or more control channel elements (CCEs), each CCE including nine RE groups (REGs), each REG including four consecutive REs in an OFDM symbol. A primary synchronization signal (PSS) may be within symbol 2 of particular subframes of a frame. The PSS is used by a UE  104  to determine subframe/symbol timing and a physical layer identity. A secondary synchronization signal (SSS) may be within symbol 4 of particular subframes of a frame. The SSS is used by a UE to determine a physical layer cell identity group number and radio frame timing. Based on the physical layer identity and the physical layer cell identity group number, the UE can determine a physical cell identifier (PCI). Based on the PCI, the UE can determine the locations of the aforementioned DM-RS. The physical broadcast channel (PBCH), which carries a master information block (MIB), may be logically grouped with the PSS and SSS to form a synchronization signal (SS)/PBCH block. The MIB provides a number of RBs in the system bandwidth and a system frame number (SFN). The physical downlink shared channel (PDSCH) carries user data, broadcast system information not transmitted through the PBCH such as system information blocks (SIBs), and paging messages. 
     As illustrated in  FIG.  2 C , some of the REs carry DM-RS (indicated as R for one particular configuration, but other DM-RS configurations are possible) for channel estimation at the base station. The UE may transmit DM-RS for the physical uplink control channel (PUCCH) and DM-RS for the physical uplink shared channel (PUSCH). The PUSCH DM-RS may be transmitted in the first one or two symbols of the PUSCH. The PUCCH DM-RS may be transmitted in different configurations depending on whether short or long PUCCHs are transmitted and depending on the particular PUCCH format used. Although not shown, the UE may transmit sounding reference signals (SRS). The SRS may be used by a base station for channel quality estimation to enable frequency-dependent scheduling on the UL. 
       FIG.  2 D  illustrates an example of various UL channels within a subframe of a frame. The PUCCH may be located as indicated in one configuration. The PUCCH carries uplink control information (UCI), such as scheduling requests, a channel quality indicator (CQI), a precoding matrix indicator (PMI), a rank indicator (RI), and HARQ ACK/NACK feedback. The PUSCH carries data, and may additionally be used to carry a buffer status report (BSR), a power headroom report (PHR), and/or UCI. 
       FIG.  3    is a block diagram of a base station  310  in communication with a UE  350  in an access network. In the DL, IP packets from the EPC  160  may be provided to a controller/processor  375 . The controller/processor  375  implements layer 3 and layer 2 functionality. Layer 3 includes a radio resource control (RRC) layer, and layer 2 includes a service data adaptation protocol (SDAP) layer, a packet data convergence protocol (PDCP) layer, a radio link control (RLC) layer, and a medium access control (MAC) layer. The controller/processor  375  provides RRC layer functionality associated with broadcasting of system information (e.g., MIB, SIBs), RRC connection control (e.g., RRC connection paging, RRC connection establishment, RRC connection modification, and RRC connection release), inter radio access technology (RAT) mobility, and measurement configuration for UE measurement reporting; PDCP layer functionality associated with header compression / decompression, security (ciphering, deciphering, integrity protection, integrity verification), and handover support functions; RLC layer functionality associated with the transfer of upper layer packet data units (PDUs), error correction through ARQ, concatenation, segmentation, and reassembly of RLC service data units (SDUs), re-segmentation of RLC data PDUs, and reordering of RLC data PDUs; and MAC layer functionality associated with mapping between logical channels and transport channels, multiplexing of MAC SDUs onto transport blocks (TBs), demultiplexing of MAC SDUs from TBs, scheduling information reporting, error correction through HARQ, priority handling, and logical channel prioritization. 
     The transmit (TX) processor  316  and the receive (RX) processor  370  implement layer 1 functionality associated with various signal processing functions. Layer 1, which includes a physical (PHY) layer, may include error detection on the transport channels, forward error correction (FEC) coding/decoding of the transport channels, interleaving, rate matching, mapping onto physical channels, modulation/demodulation of physical channels, and MIMO antenna processing. The TX processor  316  handles mapping to signal constellations based on various modulation schemes (e.g., binary phase-shift keying (BPSK), quadrature phase-shift keying (QPSK), M-phase-shift keying (M-PSK), M-quadrature amplitude modulation (M-QAM)). The coded and modulated symbols may then be split into parallel streams. Each stream may then be mapped to an OFDM subcarrier, multiplexed with a reference signal (e.g., pilot) in the time and/or frequency domain, and then combined together using an Inverse Fast Fourier Transform (IFFT) to produce a physical channel carrying a time domain OFDM symbol stream. The OFDM stream is spatially precoded to produce multiple spatial streams. Channel estimates from a channel estimator  374  may be used to determine the coding and modulation scheme, as well as for spatial processing. The channel estimate may be derived from a reference signal and/or channel condition feedback transmitted by the UE  350 . Each spatial stream may then be provided to a different antenna  320  via a separate transmitter 318TX. Each transmitter 318TX may modulate an RF carrier with a respective spatial stream for transmission. 
     At the UE  350 , each receiver  354 RX receives a signal through its respective antenna  352 . Each receiver  354 RX recovers information modulated onto an RF carrier and provides the information to the receive (RX) processor  356 . The TX processor  368  and the RX processor  356  implement layer 1 functionality associated with various signal processing functions. The RX processor  356  may perform spatial processing on the information to recover any spatial streams destined for the UE  350 . If multiple spatial streams are destined for the UE  350 , they may be combined by the RX processor  356  into a single OFDM symbol stream. The RX processor  356  then converts the OFDM symbol stream from the time-domain to the frequency domain using a Fast Fourier Transform (FFT). The frequency domain signal comprises a separate OFDM symbol stream for each subcarrier of the OFDM signal. The symbols on each subcarrier, and the reference signal, are recovered and demodulated by determining the most likely signal constellation points transmitted by the base station  310 . These soft decisions may be based on channel estimates computed by the channel estimator  358 . The soft decisions are then decoded and deinterleaved to recover the data and control signals that were originally transmitted by the base station  310  on the physical channel. The data and control signals are then provided to the controller/processor  359 , which implements layer 3 and layer 2 functionality. 
     The controller/processor  359  can be associated with a memory  360  that stores program codes and data. The memory  360  may be referred to as a computer-readable medium. In the UL, the controller/processor  359  provides demultiplexing between transport and logical channels, packet reassembly, deciphering, header decompression, and control signal processing to recover IP packets from the EPC  160 . The controller/processor  359  is also responsible for error detection using an ACK and/or NACK protocol to support HARQ operations. 
     Similar to the functionality described in connection with the DL transmission by the base station  310 , the controller/processor  359  provides RRC layer functionality associated with system information (e.g., MIB, SIBs) acquisition, RRC connections, and measurement reporting; PDCP layer functionality associated with header compression / decompression, and security (ciphering, deciphering, integrity protection, integrity verification); RLC layer functionality associated with the transfer of upper layer PDUs, error correction through ARQ, concatenation, segmentation, and reassembly of RLC SDUs, re-segmentation of RLC data PDUs, and reordering of RLC data PDUs; and MAC layer functionality associated with mapping between logical channels and transport channels, multiplexing of MAC SDUs onto TBs, demultiplexing of MAC SDUs from TBs, scheduling information reporting, error correction through HARQ, priority handling, and logical channel prioritization. 
     Channel estimates derived by a channel estimator  358  from a reference signal or feedback transmitted by the base station  310  may be used by the TX processor  368  to select the appropriate coding and modulation schemes, and to facilitate spatial processing. The spatial streams generated by the TX processor  368  may be provided to different antenna  352  via separate transmitters  354 TX. Each transmitter  354 TX may modulate an RF carrier with a respective spatial stream for transmission. 
     The UL transmission is processed at the base station  310  in a manner similar to that described in connection with the receiver function at the UE  350 . Each receiver 318RX receives a signal through its respective antenna  320 . Each receiver 318RX recovers information modulated onto an RF carrier and provides the information to a RX processor  370 . 
     The controller/processor  375  can be associated with a memory  376  that stores program codes and data. The memory  376  may be referred to as a computer-readable medium. In the UL, the controller/processor  375  provides demultiplexing between transport and logical channels, packet reassembly, deciphering, header decompression, control signal processing to recover IP packets from the UE  350 . IP packets from the controller/processor  375  may be provided to the EPC  160 . The controller/processor  375  is also responsible for error detection using an ACK and/or NACK protocol to support HARQ operations. 
     At least one of the TX processor  368 , the RX processor  356 , and the controller/processor  359  of the UE  350  may be configured to perform aspects in connection with the example UE power control handling component  198  of  FIG.  1   . 
     In some examples, a wireless device (e.g., a user equipment (UE)) may be connected to more than one network entity at a time. For example, a UE configured for dual connectivity may be connected to two different base stations, and each base station may include a cell group. In some such examples, each cell group may include one or more serving cells (sometimes referred to as “carriers”). A master cell group (MCG) is a cell group that includes at least a primary serving cell and may also include one or more secondary serving cells. A secondary cell group (SCG) is a cell group that includes one or more additional serving cells. In some examples, the UE may communicate with the MCG via a primary serving cell of the MCG (e.g., an MCG primary serving cell or “MCG PCell”). The UE may also communicate with the SCG via a serving cell of the SCG (e.g., a secondary serving cell or a secondary cell). In some examples, the SCG may be non-collocated with the MCG. For example, the SCG may be disparate from the MCG and both cell groups may be connected via a communication link. 
       FIG.  4    illustrates an example wireless communication system  400 , in accordance with the teachings disclosed herein. The example wireless communication system  400  of  FIG.  4    includes a master base station  402  including a set or group of serving cells (sometimes referred to as a “master cell group” (MCG)) that may be configured to serve a UE  404 . The MCG  402  may include a primary serving cell (PCell)  410  and one or more secondary serving cells (SCell)  412 . The example wireless communication system  400  of  FIG.  4    also includes a secondary base station  406  including a set or group of serving cells (sometimes referred to as a “secondary cell group” (SCG)) that may be configured to serve the UE  404 . The SCG  406  may include a primary serving cell (SCG PCell)  420  and one or more secondary serving cells (SCell)  422 . In the illustrated example, the UE  404  may communicate with the MCG  402  via a first communication link  414  and may communicate with the SCG  406  via a second communication link  424 . 
     In the illustrated example of  FIG.  4   , the MCG  402  includes one secondary serving cell  412  and the SCG  406  includes one secondary serving cell  422  for clarity. However, it should be appreciated that in additional or alternative examples, the MCG  402  and/or the SCG  406  may include any reasonable quantity of secondary serving cells. For example, the MCG  402  may include zero, one, two, three, etc. secondary serving cells. 
     In the illustrated example, the UE  404  may be configured to operate with dual connectivity when the UE  404  is connected to the MCG  402  and the SCG  406 . In some examples, to facilitate dual connectivity at the UE  404 , the UE  404  may be configured to include two modems. In some such examples, the first modem may be configured to connect with a first cell group (e.g., the MCG  402 ) and the second modem may be configured to connect with a second cell group (e.g., the SCG  406 ). As used herein, the term “modem” generally refers to the TX processor  368 , the RX processor  356 , and the controller/processor  359  of the UE  350  of  FIG.  3   . 
     In some examples in which the UE  404  includes two modems, information from one modem to the other modem may not be shared and/or may not be shared in a timely-manner. For example, the first modem may not be able to determine whether the second modem is transmitting an uplink transmission to the SCG  406  and/or the second modem may not be able to determine whether the first modem is transmitting an uplink transmission to the SCG  406 . 
     In some examples, to facilitate dual connectivity at the UE  404 , the UE  404  may be configured to include a single modem. In some examples, the single modem of the UE  404  may be configured to enable the UE  404  to connect to the first cell group (e.g., the MCG  402 ) and to connect to the second cell group (e.g., the SCG  406 ). In some such examples, information regarding each connection may be shared across the modem. For example, the UE  404  may be able to determine whether the UE  404  is transmitting an uplink transmission to the MCG  402  and/or transmitting an uplink transmission to the SCG  406 . 
     In some examples, each cell group (e.g., the MCG and the SCG) connected to the UE may transmit respective transmit power control (TPC) commands to the UE. The TPC command may indicate a maximum transmit power that the UE may apply to a transmission when, for example, transmitting an uplink transmission to the respective cell group. For example, the MCG may transmit an MCG TPC command to the UE to configure a maximum transmit power that the UE may apply to an uplink transmission when transmitting to the MCG. Similarly, the SCG may transmit an SCG TPC command to the UE to configure a maximum transmit power that the UE may apply to an uplink transmission when transmitting to the SCG. 
     However, it should be appreciated that in some examples, the UE  404  may receive respective grants of uplink resources for uplink transmissions to the MCG  402  and the SCG  406 . In some such examples, the UE  404  may determine that a transmit power to transmit the uplink transmissions may exceed a maximum transmit power threshold of the UE. For example, the combined transmit power for the MCG uplink transmission and the SCG uplink transmission may exceed a maximum transmit power of the UE (e.g., 23 dB). 
     Accordingly, disclosed examples provide techniques for employing power sharing for uplink transmissions for a UE. In some examples, the UE may be configured with semi-static power sharing techniques. In some examples, the UE may be configured with dynamic power sharing techniques. 
     As described above, in some examples, the UE  404  may include two modems to facilitate dual-connectivity. In some such examples, information corresponding to the first modem may not be available and/or may not be available in a timely-manner to the second modem, and vice versa. Accordingly, semi-static power sharing techniques may be employed for a UE in which information from a first modem may not be shared in a timely-manner with the other modem. For example, when a UE is configured with semi-static power sharing techniques, each modem of the UE controls its respective transmit power control using semi-static information that may be available to each modem. 
     In some examples, the semi-static information may include respective transmit powers for each cell group and the sum of the respective transmit powers may be configured to not exceed the maximum transmit power threshold of the UE (e.g., 23 dB). For example, the UE  404  may be configured with an MCG transmit power to use when transmitting an uplink transmission to the MCG  402  and may be configured with an SCG transmit power to use when transmitting an uplink transmission to the SCG  406 . In some such examples, the summation of the MCG transmit power and the SCG transmit power may be configured to be less than or equal to the maximum transmit power threshold of the UE (e.g., the MCG transmit power + the SCG transmit power is less than or equal to the maximum transmit power of the UE). However, it should be appreciated that in some such examples, the transmit power for uplink transmissions to each cell group may be a static value (e.g., uplink transmissions to the MCG  402  are transmitted at the MCG transmit power and uplink transmissions to the SCG  406  are transmitted at the SCG transmit power) and, thus, may result in examples in which degraded transmit power is employed. For example, the transmit power for uplink transmissions to the MCG  402  may be limited to the MCG transmit power even when there are no scheduled uplink transmissions to the SCG. 
     In some examples, the semi-static information may include semi-statically configured frame structures configured for each serving cell (PCell and/or SCell) in connection with the UE  404 . For example, when a serving cell of the MCG  402  and/or the SCG  406  establishes a connection with the UE  404 , the respective serving cell may provide a frame structure including a plurality of symbols and transmission directions associated with each of the symbols. For example, a symbol may be configured for an uplink transmission, a downlink transmission, or a flexible transmission that may be used for an uplink transmission and/or a downlink transmission. Thus, it should be appreciated that the frame structure may include a mix of uplink symbols, downlink symbols, and flexible symbols. It should be appreciated that the transmission direction associated with a symbol indicates whether the direction of transmission that the UE may correspond to a downlink transmission or an uplink transmission (or a flexible transmission) and not to whether an actual transmission is transmitted (during an uplink symbol) or received (during a downlink symbol). 
     Accordingly, in some examples, the UE  404  may be capable of checking the transmission direction for corresponding symbols associated with different serving cells to determine whether the UE is configured for an overlapping uplink transmission. For example, the UE  404  may be scheduled to transmit an uplink transmission on a symbol N of a TDD frame structure to the MCG  402  and may also be connected to two serving cells  422 ,  424  of the SCG  406 . In some such examples, the UE  404  may check the direction of the corresponding symbol (e.g., symbol N) of the respective TDD frame structures for the two serving cells  422 ,  424  of the SCG  406  and determine a transmit power for the uplink transmission to the MCG  402  based on the determined directions. For example, when the corresponding symbol (e.g., symbol N) of the respective TDD frame structures for the serving cells  422 ,  424  indicates a downlink transmission, the UE  404  may determine that the UE  404  is not configured to transmit an uplink transmission to the SCG  406  during that symbol (e.g., symbol N). In some such examples, the UE  404  may determine to transmit the uplink transmission to the MCG  402  using a transmit power up to the maximum transmit power threshold of the UE (e.g., 23 dB). 
     However, if the transmission direction for at least one of the corresponding symbols (e.g., symbol N) of the respective TDD frame structures for the serving cells  422 ,  424  indicates an uplink transmission or a flexible transmission, the UE  404  may determine that an uplink transmission to at least one of the serving cells  422 ,  424  may be possible during the symbol of interest (e.g., symbol N). That is, while the first modem configured to transmit the uplink transmission to the MCG  402  may be unable to determine whether the second modem is actually transmitting an uplink transmission to the SCG  406  based on shared information, the first modem may be able to use the semi-static information corresponding to the transmission directions for the frame structures to determine whether the second modem is capable of transmitting an uplink transmission during the overlapping symbol (e.g., the symbol N). In some such examples when the second modem may be capable of transmitting an uplink transmission to the SCG  406 , the UE  404  may determine to transmit the uplink transmission to the MCG  402  using a predetermined transmit power (e.g., the MCG transmit power). 
     Although the above example describes a scheduled uplink transmission to the MCG  402  and determining the transmission direction of the corresponding symbol(s) of the serving cell(s) of the SCG  406 , it should be appreciated that in other examples, the uplink transmission may be scheduled with the MCG  402  and the UE  404  may determine the transmission direction of the corresponding symbol(s) of the serving cell(s) of the MCG  402  (e.g., the serving cells  410 ,  412 ) to determine the transmit power for the scheduled uplink transmission to the SCG  406 . 
     Thus, it should be appreciated that when the UE  404  is configured with the semi-static power control mode, in some examples, the UE  404  may determine the transmit power for an uplink transmission to be a static value (e.g., the MCG transmit power). Furthermore, it should be appreciated that in some examples, the UE  404  may determine the transmit power for an uplink transmission based on an uplink capability of the other modem of the UE  404 . In either example, when employing semi-static information for determining the transmit power for an uplink transmission, the UE  404  determines the transmit power for an uplink transmission to a first cell group without information regarding whether the UE  404  is actually transmitting an uplink transmission to the other cell group. 
     As described above, in some examples, the UE  404  may be configured to share information regarding uplink transmissions across cell groups. For example, in some examples, the UE  404  may be configured with a single modem to facilitate dual-connectivity by enabling the UE  404  to connect to the first cell group (e.g., the MCG  402 ) and to connect to the second cell group (e.g., the SCG  406 ). In some such examples, information regarding each connection may be shared across the modem. For example, the UE  404  may be able to determine whether the UE  404  is transmitting an uplink transmission to the MCG  402  and/or transmitting an uplink transmission to the SCG  406 . It should be appreciated that the shared information may be referred to as “dynamic information” as the information for one connection may be available for determinations regarding the other connection in real-time (or nearly in real-time (e.g., in a timely-manner)). Accordingly, dynamic power sharing techniques may be employed for a UE in which information from a first connection may be shared in a timely-manner for making determinations regarding the other connection. For example, when a UE is configured with dynamic power sharing techniques, the UE  404  may determine the transmit power for an uplink transmission to a cell group based on whether or not the UE  404  is also transmitting another uplink transmission to another cell group. 
     In some examples, when the UE is configured for dynamic power sharing, the UE may support dynamic power sharing with look-ahead power scaling or may support dynamic power sharing with no look-ahead power scaling. For example, when the UE  404  supports dynamic power sharing, the UE  404  may be configured to implement carrier aggregation techniques. For example, in some examples, the UE  404  may be scheduled to transmit an uplink transmission using two different uplink carriers and the two uplink carriers may not start at the same time. For example, the first uplink carrier may start at symbol 0 and the second uplink carrier may start at symbol 4. In some such examples, it may be possible that the UE  404  starts transmitting via the first uplink carrier (e.g., at symbol 0) and then receives an uplink grant instructing the UE  404  to start transmitting via the second uplink carrier (e.g., at symbol 4). 
     In some examples in which the UE  404  is not configured to support look-ahead power scaling, the UE  404  may not consider later transmissions when determining the transmit power for a current transmission. For example, the UE  404  may start transmitting the first uplink carrier at a transmit power up to the maximum transmit power without taking into account the second uplink carrier. In some such examples, the UE  404  may adjust (e.g., reduce) the transmit power for the first uplink carrier when the second uplink carrier starts (e.g., at symbol 4) if, for example, the UE  404  determines that the combined transmit power would exceed the maximum transmit power threshold of the UE. 
     However, when the UE  404  is configured to support look-ahead power scaling, the UE  404  may perform power scaling for uplink transmissions received at least a predetermined time in advance of a start of a symbol. For example, when the UE  404  starts transmitting the first uplink carrier (e.g., at symbol 0), the UE  404  determines a transmit power for the first uplink carrier that takes into account a transmission power for the second uplink carrier that starts at symbol 4. It should be appreciated that the “look-ahead” or the predetermined time in advance of a start of a symbol may be one or more symbols. In some examples, the predetermined time in advance may be less than a subframe. Thus, the UE  404  may perform power scaling to adjust (e.g., reduce) the transmit power of the first uplink carrier based on an indication of a future uplink transmission (e.g., the second uplink carrier at symbol 4). 
     It should be appreciated that in some examples, when the UE  404  is configured to support look-ahead power scaling, the UE  404  may adjust the transmit power for the different uplink transmissions based on respective priority levels associated with each uplink transmission. For example, different transmissions may be assigned a priority level depending on the channel type (e.g., PUCCH, PUSCH) and/or type of uplink control information it carries. In some such examples, the UE  404  may adjust the transmit powers for the respective uplink transmissions based on the priority level assigned to the transmission. For example, if the first uplink carrier is transmitting data and the second uplink carrier is transmitting ACK/NACK feedback, the UE  404  may prioritize the transmitting of the second uplink carrier by increasing the transmit power for the second uplink carrier and/or determining a transmit power for the first uplink carrier that enables the second uplink carrier to be prioritized. 
     In some examples, the serving cells of the first cell group (e.g., the serving cells  410 ,  412  of the MCG  402 ) may be within a first frequency range (FR 1 ) and the serving cells of the second cell group (e.g., the serving cells  420 ,  422  of the SCG  406 ) may also be within the first frequency range (FR 1 ). In some such examples, the UE  404  may be configured to perform power sharing techniques (e.g., semi-static power sharing or dynamic power sharing) for uplink transmissions to either cell group  402 ,  406 . 
     In some examples, the serving cells of the first cell group (e.g., the serving cells  410 ,  412  of the MCG  402 ) may be within a first frequency range (FR 1 ) while the serving cells of the second cell group (e.g., the serving cells  420 ,  422  of the SCG  406 ) may be within a second frequency range (FR 2 ). In some such examples, the UE  404  may be configured to perform power sharing techniques (e.g., semi-static power sharing or dynamic power sharing) for uplink transmissions to either cell group  402 ,  406  so that the combined transmit power at any given time does not exceed the maximum transmit power threshold of the UE. In some aspects, the FR 1  band may include a sub-6 gigahertz (GHz) frequency band and the FR 2  band may include a millimeter wave (mmW) frequency band. 
     As used herein, the first frequency range (FR 1 ) and the second frequency range (FR 2 ) correspond to different regions of a frequency spectrum. For example, a first frequency range may include 410 MHz to 7126 MHz, and a second frequency range may include 24.25 GHz to 52.6 GHz. In some examples, a first frequency range may include the sub 6 GHz spectrum, a second frequency range may include the 30 GHz to 300 GHz spectrum, a third frequency range may include the 3 GHz to 30 GHz spectrum, 
     However, in some examples, the serving cells for one or both of the cell groups may be within the first frequency range (FR 1 ) and the second frequency range (FR 2 ).  FIGS.  5 ,  6 , and  7    illustrate example band combinations in which serving cells for one or both of the cell groups may be within the first frequency range (FR 1 ) and the second frequency range (FR 2 ). 
       FIG.  5    illustrates a first example scenario  500  including a band combination  502  corresponding to a UE operating in dual connectivity with a first cell group (e.g., an MCG  504 ) and a second cell group (e.g., an SCG  506 ). In the illustrated example of  FIG.  5   , the band combination  502  includes band  1 , band  3 , band  7 , band  8 , band  257 , and band  258 , and each band corresponds to a serving cell. Thus, as shown in  FIG.  5   , the UE is connected to the MCG  504  via MCG serving cells corresponding to band  1 , band  3 , and band  257 . The UE is also connected to the SCG  506  via SCG serving cells corresponding to band  7 , band  8 , and band  258 . 
     In the illustrated example of  FIG.  5   , the MCG serving cells include a first set of serving cells within a first frequency range (FR 1 ) (e.g., the serving cells corresponding to band  1  and band  3 ) and a second set of serving cells within a second frequency range (FR 2 ) (e.g., the serving cell corresponding to band  257 ). Similarly, the SCG serving cells include a first set of serving cells within the first frequency range (FR 1 ) (e.g., the serving cells corresponding to band  7  and band  8 ) and a second set of serving cells within the second frequency range (FR 2 ) (e.g., the serving cell corresponding to band  258 ). 
       FIG.  6    illustrates a second example scenario  600  including a band combination  602  corresponding to a UE operating in dual connectivity with a first cell group (e.g., an MCG  604 ) and a second cell group (e.g., an SCG  606 ). In the illustrated example of  FIG.  6   , the band combination  602  includes band  1 , band  3 , band  7 , band  8 , and band  258 , and each band corresponds to a serving cell. Thus, as shown in  FIG.  6   , the UE is connected to the MCG  604  via MCG serving cells corresponding to band  1  and band  3 . The UE is also connected to the SCG  606  via SCG serving cells corresponding to band  7 , band  8 , and band  258 . 
     In the illustrated example of  FIG.  6   , the MCG serving cells include a first set of serving cells within a first frequency range (FR 1 ) (e.g., the serving cells corresponding to band  1  and band  3 ). Similarly, the SCG serving cells include a first set of serving cells within the first frequency range (FR 1 ) (e.g., the serving cells corresponding to band  7  and band  8 ) and a second set of serving cells within the second frequency range (FR 2 ) (e.g., the serving cell corresponding to band  258 ). 
     Although the illustrated example of  FIG.  6    depicts the first set of serving cells of the MCG  604  within the first frequency range (FR 1 ), it should be appreciated that in other examples, the first set of serving cells of the MCG  604  may be within the second frequency range (FR 2 ). 
       FIG.  7    illustrates a third example scenario  700  including a band combination  702  corresponding to a UE operating in dual connectivity with a first cell group (e.g., an MCG  704 ) and a second cell group (e.g., an SCG  706 ). In the illustrated example of  FIG.  7   , the band combination  702  includes band  1 , band  3 , band  257 , and band  258 , and each band corresponds to a serving cell. Thus, as shown in  FIG.  7   , the UE is connected to the MCG  704  via MCG serving cells corresponding to band  1 , band  3 , and band  257 . The UE is also connected to the SCG  706  via an SCG serving cell corresponding to the band  258 . 
     In the illustrated example of  FIG.  7   , the MCG serving cells include a first set of serving cells within a first frequency range (FR 1 ) (e.g., the serving cells corresponding to band  1  and band  3 ) and a second set of serving cells within a second frequency range (FR 2 ) (e.g., the serving cell corresponding to band  257 ). Similarly, the SCG serving cells include a first set of serving cells within the second frequency range (FR 2 ) (e.g., the serving cell corresponding to band  258 ). 
     Although the illustrated example of  FIG.  7    depicts the first set of serving cells of the SCG  706  within the second frequency range (FR 2 ), it should be appreciated that in other examples, the first set of serving cells of the SCG  706  may be within the first frequency range (FR 1 ). 
     Based on the illustrated example scenarios of  FIGS.  5 ,  6 , and  7   , it should be appreciated that in some examples, the MCG carriers and the SCG carriers may overlap for at least one of the frequency ranges (e.g., in the second example scenario  600  of  FIG.  6    and in the third example scenario  700  of  FIG.  7   ) or may overlap for both frequency ranges (e.g., in the first example scenario  500  of  FIG.  5   ). 
     For example, based on the illustrated first example scenario  500  of  FIG.  5   , when the UE is transmitting an uplink transmission to the MCG  504  and/or the SCG  506 , the UE may be using carriers in the first frequency range (FR 1 ) and the second frequency range (FR 2 ). Additionally, based on the illustrated second example scenario  600  of  FIG.  6   , when the UE is transmitting an uplink transmission to the MCG  604  and/or the SCG  606 , there may be an overlap in carriers within the first frequency range (FR 1 ) and no overlap in carriers within the second frequency range (FR 2 ). Furthermore, based on the illustrated third example scenario  700  of  FIG.  7   , when the UE is transmitting an uplink transmission to the MCG  704  and/or the SCG  706 , there may be an overlap in carriers within the second frequency range (FR 2 ) and no overlap in carriers within the first frequency range (FR 1 ). 
     Example techniques disclosed herein enable the UE to be configured with power control modes for each frequency range within which the UE may be connected. For example, when the MCG serving cells and the SCG serving cells overlap within a first frequency range (FR 1 ) and also overlap within a second frequency range (FR 2 ) (as shown in the first example scenario  500  of  FIG.  5   ), the UE may be configured with a first power control mode for the first frequency range (FR 1 ) and may be configured with a second power control mode for the second frequency range (FR 2 ). In some such examples, the first power control mode may correspond to semi-static power sharing techniques and/or to dynamic power sharing techniques. Similarly, the second power control mode may correspond to semi-static power sharing techniques and/or to dynamic power sharing techniques. 
     In some examples in which the MCG serving cells and the SCG serving cells overlap within one of the frequency ranges and do not overlap within the other frequency range (e.g., as shown in the second example scenario  600  of  FIG.  6    and the third example scenario  700  of  FIG.  7   ), the UE may be configured with a first power control mode for the frequency range including the overlapping serving cells and may be configured with a second power control mode for the other frequency range. In some such examples, the first power control mode may correspond to semi-static power sharing techniques and/or to dynamic power sharing techniques. In some examples, the second power control mode may not correspond to a power sharing technique. That is, the second power control mode may enable the UE to operate at a transmit power up to the maximum transmit power threshold of the UE for serving cells within the non-overlapped frequency range (e.g., the second frequency range (FR 2 ) in the second example scenario  600  of  FIG.  6    or the first frequency range (FR 1 ) in the third example scenario  700  of  FIG.  7   ). 
       FIG.  8    illustrates an example wireless communication  800  between a first cell group  802 , a UE  804 , and a second cell group  806 , as presented herein. One or more aspects of the cell groups  802 ,  806  may be implemented by the base station  180  of  FIG.  1   , the base station  310  of  FIG.  3   , and/or the cell groups  402 ,  404  of  FIG.  4   . One or more aspects of the UE  804  may be implemented by the UE  104  of  FIG.  1   , the UE  350  of  FIG.  3   , and/or the UE  404  of  FIG.  4   . 
     In the illustrated example of  FIG.  8   , the UE A04 is configured to support dual connectivity. Furthermore, the first cell group  802  and the second cell group  806  may support NR communication technologies. Accordingly, the UE  804  may be configured to support NR-NR dual connectivity (sometimes referred to as “NR-DC,” NR-NR DC,″ or “NN-DC”). 
     In the illustrated example of  FIG.  8   , the UE  804  searches for and synchronizes with, at  810 , a primary cell (PCell) of the first cell group  802 . In some examples, the UE  804  may perform the searching for and synchronizing with the PCell of the first cell group  802  after powering-on. 
     The UE  804  may then establish a connection, at  812 , with the first cell group  802  via the primary cell of the first cell group  802 . In some examples, the connection may be established according to connection establishment techniques in which the UE  804  may request a connection (e.g., via a random access request) with the first cell group  802 . 
     In some examples, the UE  804  may also transmit capability signaling  814  during the connection establishment techniques. In some examples, the capability signaling  814  includes a power sharing capability report of the UE  804  for each frequency range supported by the UE  804  when operating in dual connectivity. In some examples, the power sharing capability report indicates whether the UE  804  supports semi-static power sharing and/or a dynamic power sharing. In some examples, the UE  804  may transmit the capability signaling  814  via radio resource control (RRC) signaling. 
     The first cell group  802  (e.g., the PCell of the first cell group  802 ) may then determine, at  816 , a transmit power configuration for the UE  804  for each frequency range. For example, the first cell group  802  may determine a first power control mode for the first frequency range (FR 1 ) and a second power control mode for the second frequency range (FR 2 ). In some examples, the first cell group  802  may determine the transmit power configuration based on the capability signaling  814  received from the UE  804 . For example, the first cell group  802  may determine the first power control mode for the first frequency range (FR 1 ) based on which semi-static power sharing capabilities and/or dynamic power sharing capabilities the UE  804  reported via the capability signaling  814  that the UE  804  supported (or did not support) for the first frequency range (FR 1 ). The first cell group  802  may also determine the second power control mode for the second frequency range (FR 2 ) based on which semi-static power sharing capabilities and/or dynamic power sharing capabilities the UE  804  reported via the capability signaling  814  that the UE  804  supported (or did not support) for the second frequency range (FR 2 ). 
     The first cell group  802  (e.g., the PCell of the first cell group  802 ) may then transmit a transmit power configuration  818  to the UE  804 . In some examples, the transmit power configuration  818  may include the first power control mode and the second power control mode. In some examples, the first cell group  802  may transmit the transmit power configuration  818  to the UE  804  via RRC signaling. In some examples, the transmit power configuration  818  may include the semi-static information used by the UE  804  when the UE supports semi-static power sharing. For example, the transmit power configuration  818  may include the MCG transmit power and the SCG transmit power when the UE  804  is configured to determine the transmit power based on the static capability supported by the UE  804 . In some examples, the transmit power configuration  818  may include the MCG transmit power and the SCG transmit power when the UE  804  is configured to determine transmit power based on the semi-dynamic capability supported by the  804 . 
     After receiving the transmit power configuration  818  from the first cell group  802 , the UE may then establish dual connectivity with a second cell group. For example, the UE  804  may search for and synchronize with, at  820 , a primary cell (PCell) of the second cell group  806 . 
     The UE  804  may then establish a connection, at  822 , with the second cell group  806  via the primary cell of the second cell group  806 . In some examples, the connection may be established according to connection establishment techniques in which the UE  804  may request a connection (e.g., via a random access request) with the second cell group  806 . In some examples, after the UE  804  establishes the connection with the second cell group  806 , the first cell group  802  may be referred to as the master cell group and the second cell group  806  may be referred to as the secondary cell group. 
     In some examples, after the UE  804  establishes dual connectivity (e.g., with the one or more serving cells of the MCG  802  and the one or more serving cells of the SCG  806 ), the UE  804  may receive an uplink transmission grant. For example, the UE  804  may receive an uplink transmission grant  824  from the MCG  802 . It should be appreciated that the uplink transmission grant  824  may schedule uplink resources for one or more uplink transmissions. In some examples, the MCG  802  may provide the uplink transmission grant  824  via downlink control information (DCI) that is transmitted to the UE  804 . 
     The UE  804  may then determine, at  826 , a transmit power for an uplink transmission to the MCG  802 . In some examples, the UE  804  may determine the transmit power for each frequency range based on the transmit power configuration  818  received from the MCG  802 . For example, the UE  804  may be configured to apply (based on the transmit power configuration  818 ) the static capability, the semi-dynamic capability, the dynamic without look-ahead capability, or the dynamic with look-ahead capability to determine the transmit power for the uplink transmission to the MCG  802 . 
     The UE  804  may then transmit an uplink transmission  828  to the MCG  802  using the determined transmit power. 
     In some examples, the MCG  802  may determine that capabilities and/or conditions have changed that may result in different transmit power configurations that may apply to the UE  804 . For example, a change in channel qualities across different frequencies may cause the MCG  802  to determine, at  830 , an updated transmit power configuration for the UE  804 . The MCG  802  may then transmit the updated transmit power configuration  832  to the UE  804 . In some examples, the MCG  802  may transmit the updated transmit power configuration  832  to the UE  804  via RRC signaling. 
     In some examples, the capability signaling  814  may report whether the UE supports semi-static power sharing for each frequency range (e.g., the FR 1  and the FR 2 ). In some such examples, the UE may also report a semi-static power sharing capability based on the type of semi-static information available to the UE. For example, the UE may report whether the UE is capable of checking transmission directions for corresponding symbols based on semi-static frame structures provided for different serving cells in communication with the UE (sometimes referred to herein as a “semi-dynamic capability” as the UE may utilize semi-static information to determine a transmit power that may be up to a maximum transmit power threshold of the UE). Additionally or alternatively, the UE may report whether the UE is capable of determining the transmit power for an uplink transmission based on static values provided to the UE (sometimes referred to herein as a “static capability” as the UE may utilize semi-static information to determine a static transmit power for an uplink transmission (e.g., the MCG transmit power or the SCG transmit power). 
     In some examples, the capability signaling  814  may report whether the UE supports dynamic power sharing for each frequency range (e.g., the FR 1  and the FR 2 ). In some such examples, the UE may also report a dynamic power sharing capability. For example, the UE may report whether the UE supports dynamic power sharing with look-ahead power scaling (sometimes referred to herein as a “dynamic with look-ahead capability” as the UE may utilize dynamic (or shared) information regarding a future uplink transmission to determine a transmit power for a current uplink transmission). Additionally or alternatively, the UE may report whether the UE supports dynamic power sharing without look-ahead power scaling (sometimes referred to herein as a “dynamic without look-ahead capability” as the UE may utilize dynamic (or shared) information to determine a transmit power for a current uplink transmission). 
     In some examples, the capability signaling  814  may report the power sharing capabilities of the UE per frequency range. For example, the power sharing capability report may include the one or more band combinations supported by the UE. The power sharing capability report may also include, for each frequency range that the UE supports, whether the UE supports semi-static power sharing and, if so, which semi-static power sharing capabilities (e.g., the semi-dynamic capability and/or the static capability) the UE supports or does not support. For example, the power sharing capability report may include each of the one or more band combinations supported by the UE, whether the UE supports semi-static power sharing for the first frequency range (FR 1 ) (and, if so, whether the UE supports the semi-dynamic capability and/or the static capability for the first frequency range), and whether the UE supports semi-static power sharing for the second frequency range (FR 2 ) (and, if so, whether the UE supports the semi-dynamic capability and/or the static capability for the second frequency range). 
     In some examples, the power sharing capability report may additionally or alternatively include, for each frequency range that the UE supports, whether the UE supports dynamic power sharing and, if so, which dynamic power sharing capabilities (e.g., the dynamic with look-ahead capability and/or the dynamic without look-ahead capability) the UE supports or does not support. For example, the power sharing capability report may include each of the one or more band combinations supported by the UE, whether the UE supports dynamic power sharing for the first frequency range (FR 1 ) (and, if so, whether the UE supports the dynamic with look-ahead capability and/or the dynamic without look-ahead capability for the first frequency range), and whether the UE supports dynamic power sharing for the second frequency range (FR 2 ) (and, if so, whether the UE supports the dynamic with look-ahead capability and/or the dynamic without look-ahead capability for the second frequency range). 
     Thus, it should be appreciated that in some examples, the UE may support only semi-static power sharing, may support only dynamic power sharing, and/or may support a combination of semi-static power sharing and dynamic power sharing. For example, the UE may support semi-static power sharing for the first frequency range (FR 1 ) and may support dynamic power sharing for the second frequency range (FR 2 ). Additionally or alternatively, the UE may support both semi-static power sharing and dynamic power sharing for the first frequency range (FR 1 ) and/or the second frequency range (FR 2 ). 
     In some examples, the power sharing capability report may include information per band combination for each frequency range. For example, the UE may support three band combinations (e.g., the band combinations  502 ,  602 ,  702  of  FIGS.  5 ,  6 , and  7   ) across the first frequency range (FR 1 ) and the second frequency range (FR 2 ). In some such examples, the power sharing capability report may include the bands of the first band combination (e.g., the band combination  502  including band  1 , band  3 , band  7 , band  8 , band  257 , and band  258 ), which power sharing capabilities the UE  804  supports (or does not support) for the first frequency range (FR 1 ) for the first band combination, and which power sharing capabilities the UE  804  supports (or does not support) for the second frequency range (FR 2 ) for the first band combination. The power sharing capability report may also include the bands of the second band combination (e.g., the band combination  602  including band  1 , band  3 , band  7 , band  8 , and band  258 ), which power sharing capabilities the UE  804  supports (or does not support) for the first frequency range (FR 1 ) for the second band combination, and which power sharing capabilities the UE  804  supports (or does not support) for the second frequency range (FR 2 ) for the second band combination. The power sharing capability report may also include the bands of the third band combination (e.g., the band combination  702  including band  1 , band  3 , band  257 , and band  258 ), which power sharing capabilities the UE  804  supports (or does not support) for the first frequency range (FR 1 ) for the third band combination, and which power sharing capabilities the UE  804  supports (or does not support) for the second frequency range (FR 2 ) for the third band combination. 
     It should be appreciated that in some examples, the UE may indicate which of the semi-static power sharing capabilities (e.g., the static capability and/or the semi-dynamic capability) and/or the dynamic power sharing capabilities (e.g., the dynamic without look-ahead capability and/or the dynamic with look-ahead capability) that the UE supports and the cell group may determine whether the UE supports semi-static power sharing and/or dynamic power sharing accordingly. For example, in some examples, the power sharing capability report may include whether the UE supports semi-static power sharing and which of the semi-static power sharing capabilities the UE supports (or does not support) for each frequency range, and in some other examples, the power sharing capability report may include which of the semi-static power sharing capabilities the UE supports (or does not support) for each frequency range (e.g., does not include whether the UE supports semi-static power sharing). 
     It should be appreciated that in some examples, the UE  804  may additionally or alternatively transmit capability signaling to the SCG  806 . 
     In some examples, the SCG  806  may determine a transmit power configuration for the UE  804  and may transmit the determined transmit power configuration to the UE  804 . In some such examples, the SCG  806  may transmit the determined transmit power configuration to the UE  804  via RRC signaling. 
       FIG.  9    is a flowchart of a method  900  of wireless communication. The method  900  may be performed by a UE (e.g., the UE  104 , the UE  350 , the UE  404 , the UE  804 , the apparatus  1202 / 1202 , the processing system  1314 , which may include the memory  360  and which may be the entire UE  350  or a component of the UE  350 , such as the TX processor  368 , the RX processor  356 , and/or the controller/processor  359 ). Optional aspects are illustrated with a dashed line. In the illustrated example of  FIG.  9   , the method  900  may correspond to the first example scenario  500  of  FIG.  5   . 
     At  902 , the UE connects to an MCG on a first set of MCG serving cells within an FR 1  and a second set of MCG serving cells within an FR 2 , as described in connection with, for example, the connection  812  of  FIG.  8   . For example, the first cell group connection handling component  1210  may facilitate the connecting of the UE to the MCG on the first set of MCG serving cells within the FR 1  and the second set of MCG serving cells within the FR 2 . 
     At  904 , the UE connects to an SCG on a first set of SCG serving cells within the FR 1  and a second set of SCG serving cells within the FR 2 , as described in connection with, for example, the connection  822  of  FIG.  8   . For example, the second cell group connection handling component  1212  may facilitate the connecting of the UE to the SCG on the first set of SCG serving cells within the FR 1  and the second set of SCG serving cells within the FR 2 . 
     At  906 , the UE may transmit a first capability for indicating support of a first transmit power control method or a second transmit power control method for the FR 1 , as described in connection with the capabilities signaling  814  of  FIG.  8   . For example, the capabilities reporting component  1214  may facilitate the transmitting of the first capability for the FR 1 . In some examples, the first transmit power control method may include the static capability and the second transmit power control method may include the semi-dynamic capability. In some examples, the first transmit power control method may include the dynamic without look-ahead capability and the second transmit power control method may include the dynamic with look-ahead capability. However, it should be appreciated that the first transmit power control method and the second transmit power control method may include additional or alternative combinations of the semi-static power sharing capabilities and the dynamic power sharing capabilities. In some examples, the transmitting of the first capability may be per UE. In some examples, the transmitting of the first capability may be per band combination. 
     At  908 , the UE may transmit a second capability for indicating support of the first transmit power control method or the second transmit power control method for the FR 2 , as described in connection with the capabilities signaling  814  of  FIG.  8   . For example, the capabilities reporting component  1214  may facilitate the transmitting of the second capability for the FR 2 . In some examples, the first transmit power control method may include the static capability and the second transmit power control method may include the semi-dynamic capability. In some examples, the first transmit power control method may include the dynamic without look-ahead capability and the second transmit power control method may include the dynamic with look-ahead capability. However, it should be appreciated that the first transmit power control method and the second transmit power control method may include additional or alternative combinations of the semi-static power sharing capabilities and the dynamic power sharing capabilities. In some examples, the transmitting of the second capability may be per UE. In some examples, the transmitting of the second capability may be per band combination. 
     At  910 , the UE may receive a transmit power configuration for a power control mode for both FR 1  and for FR 2 , as described in connection with the transmit power configuration  818  of  FIG.  8   . For example, the transmit power configuration receiving component  1216  may facilitate the receiving of the transmit power configuration for the power control mode for both FR 1  and for FR 2 . In some examples, the transmit power configuration may include a first power control mode for the FR 1  and may include a second power control mode for the FR 2 . 
     At  912 , the UE may transmit to at least one of the MCG serving cells or the SCG serving cells with a transmit power determined based on the transmit power configuration, as described in connection with the determining of the transmit power, at  826 , and the uplink transmission  828  of  FIG.  8   .
