The disclosure of the prior application is considered to be a part of this patent application and is incorporated herein by reference. Technical Field

[0003] Aspects of the present disclosure generally relate to wireless communication and relate to techniques and apparatuses for power control for carrier aggregation and dual connectivity operation. Background Art

[0004] Wireless communication systems are widely deployed to provide various telecommunication services such as telephony, video, data, messaging, and broadcasting. A typical wireless communication system may employ a multiple access technology that is capable of supporting communication with multiple users by sharing available system resources (e.g., bandwidth, transmit power, etc.). 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 / Advanced LTE is an enhanced collection of the Universal Mobile Telecommunications System (UMTS) mobile standards promulgated by the Third Generation Partnership Project (3GPP).

[0005] A wireless network may include one or more network nodes that support communication for wireless communication devices such as user equipment (UE) or multiple UEs. A UE may communicate with a network node via downlink communication and uplink communication. "Downlink" (or "DL") refers to the communication link from the network node to the UE, and "uplink" (or "UL") refers to the communication link from the UE to the network node. Some wireless networks may support device - to - device communication, such as via local links (e.g., sidelink (SL), Wireless Local Area Network (WLAN) link, and / or Wireless Personal Area Network (WPAN) link, etc.).

[0006] The above multi-access technologies have been adopted in various telecommunication standards to provide a common protocol that enables different UEs to communicate at the urban, national, regional, and / or global levels. New Radio (NR) (which may be referred to as 5G) is an enhanced set of LTE mobile standards promulgated by 3GPP. NR is designed to better support mobile broadband Internet access by: improving spectral efficiency; reducing costs; enhancing services; leveraging new spectrums; and better integrating with other open standards by using Orthogonal Frequency Division Multiplexing with Cyclic Prefix (CP-OFDM) on the downlink, CP-OFDM and / or Single Carrier Frequency Division Multiplexing (SC-FDM) (also known as Discrete Fourier Transform Spread OFDM (DFT-s-OFDM)) on the uplink; and supporting beamforming, Multiple Input Multiple Output (MIMO) antenna technology, and carrier aggregation. With the continuous increase in the demand for mobile broadband access, further improvements in LTE, NR, and other radio access technologies remain useful. SUMMARY OF THE INVENTION

[0029] Aspects of the present disclosure are more fully described below with reference to the accompanying drawings. However, the present disclosure may be embodied in many different forms and should not be construed as limited to any specific structure or function presented throughout this disclosure. Rather, these aspects are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the present disclosure to those skilled in the art. Those skilled in the art should understand that the scope of the present disclosure is intended to cover any aspect of the disclosure disclosed herein, whether implemented independently of or in combination with any other aspect of the disclosure. For example, any number of the aspects set forth herein may be used to implement an apparatus or practice a method. Additionally, the scope of the present disclosure is intended to cover such an apparatus or method practiced using other structures, functionality, or a combination of structures and functionality in addition to or different from the aspects of the disclosure set forth herein. It should be understood that any aspect of the disclosure disclosed herein may be embodied by one or more elements of the present invention.

[0030] Aspects of a telecommunications system will now be presented with reference to various apparatus and techniques. These apparatus and techniques will be described in the following detailed description and illustrated by various boxes, modules, components, circuits, steps, processes, algorithms, etc. (collectively referred to as "elements") in the accompanying drawings. These elements can be implemented using hardware, software, or a combination thereof. Whether such elements are implemented as hardware or software depends on the particular application and the design constraints imposed on the overall system.

[0031] Although terms that are generally associated with 5G or New Radio (NR) radio access technology (RAT) may be used herein to describe aspects, aspects of the present disclosure may be applicable to other RATs, such as 3G RAT, 4G RAT, and / or post-5G (e.g., 6G) RATs.

[0032] Figure 1 FIG. is a diagram illustrating an example of a wireless network 100 according to the present disclosure. The wireless network 100 may be a 5G (e.g., NR) network and / or a 4G (e.g., Long Term Evolution (LTE)) network, or may include elements of a 5G (e.g., NR) network and / or elements of a 4G (e.g., Long Term Evolution (LTE)) network, and other examples. The wireless network 100 may include one or more network nodes 110 (shown as network nodes 110a, network nodes 110b, network nodes 110c, and network nodes 110d), user equipment (UE) 120 or multiple UEs 120 (shown as UEs 120a, UEs 120b, UEs 120c, UEs 120d, and UEs 120e), and / or other entities. The network nodes 110 are network nodes that communicate with the UEs 120. As shown, the network nodes 110 may include one or more network nodes. For example, the network nodes 110 may be aggregated network nodes, which means that the aggregated network nodes are configured to utilize a radio protocol stack that is physically or logically integrated within a single radio access network (RAN) node (e.g., within a single device or unit). As another example, the network nodes 110 may be disaggregated network nodes (sometimes referred to as disaggregated base stations), which means that the network nodes 110 are configured to utilize a protocol stack that is physically or logically distributed between two or more nodes, such as one or more central units (CUs), one or more distributed units (DUs), or one or more radio units (RUs).

[0033] In some examples, network node 110 is or includes a network node that communicates with UE 120 via a radio access link, such as an RU. In some examples, network node 110 is or includes a network node that communicates with other network nodes 110 via a fronthaul link or a midhaul link, such as a DU. In some examples, network node 110 is or includes a network node that communicates with other network nodes 110 via a midhaul link or communicates with a core network via a backhaul link, such as a CU. In some examples, network node 110 (such as an aggregated network node 110 or a disaggregated network node 110) may include multiple network nodes, such as one or more RUs, one or more CUs, and / or one or more DUs. Network node 110 may include, for example, an NR base station, an LTE base station, a Node B, an eNB (e.g., in 4G), a gNB (e.g., in 5G), an access point, a transmission and reception point (TRP), a DU, an RU, a CU, a mobility element of the network, a core network node, a network element, network equipment, a RAN node, or a combination thereof. In some examples, network node 110 may be interconnected with one another or with one or more other network nodes 110 in wireless network 100 using any suitable transport network via various types of fronthaul, midhaul, and / or backhaul interfaces, such as direct physical connections, air interfaces, or virtual networks.

[0034] In some examples, network node 110 may provide communication coverage for a specific geographical area. In the 3rd Generation Partnership Project (3GPP), depending on the context in which the term is used, the term "cell" may refer to the coverage area of network node 110 and / or the network node subsystem serving that coverage area. Network node 110 may provide communication coverage for a macrocell, a picocell, a femtocell, and / or another type of cell. A macrocell may cover a relatively large geographical area (e.g., with a radius of several kilometers) and may allow unrestricted access by UE 120 with a service subscription. A picocell may cover a relatively small geographical area and may allow unrestricted access by UE 120 with a service subscription. A femtocell may cover a relatively small geographical area (e.g., a home) and may allow restricted access by UE 120 associated with the femtocell (e.g., UE 120 in a closed subscriber group (CSG)). The network node 110 for a macrocell may be referred to as a macro network node. The network node 110 for a picocell may be referred to as a pico network node. The network node 110 for a femtocell may be referred to as a femto network node or a home network node. In Figure 1In the example shown, network node 110a can be a macro network node for macro cell 102a, network node 110b can be a pico network node for pico cell 102b, and network node 110c can be a femto network node for femto cell 102c. A network node can support one or more (e.g., three) cells. In some examples, a cell may not necessarily be stationary, and the geographical area of a cell can move according to the location of a moving network node 110 (e.g., a mobile network node).

[0035] In some aspects, the term "base station" or "network node" can refer to an aggregated base station, a disaggregated base station, an integrated access and backhaul (IAB) node, a relay node, or one or more of their components. For example, in some aspects, the "base station" or "network node" can refer to a CU, a DU, an RU, a near real-time (near RT) RAN intelligent controller (RIC), or a non-real-time (non RT) RIC, or a combination thereof. In some aspects, the term "base station" or "network node" can refer to a single device configured to perform one or more functions (such as those described herein in connection with network node 110). In some aspects, the term "base station" or "network node" can refer to multiple devices configured to perform one or more functions. For example, in some distributed systems, each of multiple different devices (which can be located at the same geographical location or different geographical locations) can be configured to perform at least a portion of a function, or to repeatedly perform at least a portion of the function, and the term "base station" or "network node" can refer to any one or more of these different devices. In some aspects, the term "base station" or "network node" can refer to one or more virtual base stations or one or more virtual base station functions. For example, in some aspects, two or more base station functions can be instantiated on a single device. In some aspects, the term "base station" or "network node" can refer to one base station function among base station functions, rather than another base station function. In this way, a single device can include more than one base station.

[0036] Wireless network 100 can include one or more relay stations. A relay station is a network node that can receive a transmission of data from an upstream node (e.g., network node 110 or UE 120) and transmit the data to a downstream node (e.g., UE 120 or network node 110). A relay station can be a UE 120 capable of relaying transmissions for other UEs 120. In Figure 1 the example shown, network node 110d (e.g., a relay network node) can communicate with network node 110a (e.g., a macro network node) and UE 120d to facilitate communication between network node 110a and UE 120d. A network node that relays communication can be referred to as a relay station, a relay base station, a relay network node, a relay node, a relay, etc.

[0037] The wireless network 100 can be a heterogeneous network that includes different types of network nodes 110, such as macro network nodes, pico network nodes, femto network nodes, relay network nodes, etc. These different types of network nodes 110 can have different transmission power levels, different coverage areas, and / or different impacts on interference in the wireless network 100. For example, a macro network node can have a high transmission power level (e.g., 5 watts to 40 watts), while pico network nodes, femto network nodes, and relay network nodes can have lower transmission power levels (e.g., 0.1 watt to 2 watts).

[0038] The network controller 130 can be coupled to or communicate with a set of network nodes 110 and can provide coordination and control for these network nodes 110. The network controller 130 can communicate with the network nodes 110 via a backhaul communication link or a midhaul communication link. The network nodes 110 can also communicate directly with each other or indirectly via a wireless or wired backhaul communication link. In some aspects, the network controller 130 can be a CU or a core network device, or can include a CU or a core network device.

[0039] UEs 120 can be dispersed throughout the wireless network 100, and each UE 120 can be stationary or mobile. The UE 120 can include, for example, an access terminal, a terminal, a mobile station, and / or a subscriber unit. The UE 120 can be a cellular phone (e.g., a smart phone), a personal digital assistant (PDA), a wireless modem, a wireless communication device, a handheld device, a laptop computer, a cordless phone, a wireless local loop (WLL) station, a tablet computer, a camera, a gaming device, a netbook, a smartbook, a superbook, a medical device, a biometric device, a wearable device (e.g., a smart watch, smart clothing, smart glasses, a smart wristband, smart jewelry (e.g., a smart ring or a smart bracelet)), an entertainment device (e.g., a music device, a video device, and / or a satellite radio), a vehicle component or sensor, a smart meter / sensor, industrial manufacturing equipment, a global positioning system device, a UE function of a network node, and / or any other suitable device configured to communicate via a wireless or wired medium.

[0040] Some UEs 120 may be considered machine type communication (MTC) or evolved or enhanced machine type communication (eMTC) UEs. The MTC UEs and / or eMTC UEs may include, for example, robots, drones, remote devices, sensors, meters, monitors, and / or location tags, which may communicate with network nodes, another device (e.g., a remote device), or some other entity. Some UEs 120 may be considered Internet of Things (IoT) devices and / or may be implemented as narrowband IoT (NB-IoT) devices. Some UEs 120 may be considered customer premise equipment. The UE 120 may be included inside a housing that houses components of the UE 120, such as processor components and / or memory components. In some examples, the processor components and the memory components may be coupled together. For example, the processor components (e.g., one or more processors) and the memory components (e.g., memory) may be operatively coupled, communicatively coupled, electronically coupled, and / or electrically coupled.

[0041] Generally, any number of wireless networks 100 may be deployed in a given geographical area. Each wireless network 100 may support a specific RAT and may operate on one or more frequencies. The RAT may be referred to as a radio technology, an air interface, etc. The frequency may be referred to as a carrier, a frequency channel, etc. Each frequency in a given geographical area may support a single RAT to avoid interference between wireless networks of different RATs. In some cases, an NR or 5G RAT network may be deployed.

[0042] In some examples, 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., communicate with each other without using the network node 110 as an intermediate device). For example, the UE 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, vehicle-to-infrastructure (V2I) protocols, or vehicle-to-pedestrian (V2P) protocols), and / or mesh networks. In such examples, the UE 120 may perform scheduling operations, resource selection operations, and / or other operations described elsewhere herein as being performed by the network node 110.

[0043] Devices of the wireless network 100 can communicate using the electromagnetic spectrum, which can be subdivided into various categories, bands, channels, etc. according to frequency or wavelength. For example, devices of the wireless network 100 can communicate using one or more operating bands. In 5G NR, two initial operating bands have been identified as Frequency Range Designation FR1 (410 MHz - 7.125 GHz) and FR2 (24.25 GHz - 52.6 GHz). It should be understood that although a part of FR1 is greater than 6 GHz, in various documents and articles, FR1 is generally (interchangeably) referred to as the "sub-6 GHz" band. Regarding FR2, a similar naming issue sometimes occurs, which is generally (interchangeably) referred to as the "millimeter wave" band in documents and articles, although it is different from the extremely high frequency (EHF) band (30 GHz - 300 GHz) identified as the "millimeter wave" band by the International Telecommunication Union (ITU).

[0044] Frequencies between FR1 and FR2 are generally referred to as mid-band frequencies. Recent 5G NR research has identified operating bands for these mid-band frequencies as Frequency Range Designation FR3 (7.125 GHz - 24.25 GHz). Bands falling within FR3 can inherit FR1 characteristics and / or FR2 characteristics, and thus can effectively extend the features of FR1 and / or FR2 to mid-band frequencies. In addition, higher bands are currently being explored to extend 5G NR operations beyond 52.6 GHz. For example, three higher operating bands have been identified as Frequency Range Designation FR4a or FR4-1 (52.6 GHz - 71 GHz), FR4 (52.6 GHz - 114.25 GHz), and FR5 (114.25 GHz - 300 GHz). Each of these higher bands falls within the EHF band.

[0045] Considering the above examples, unless otherwise specifically stated, it should be understood that if the term "sub-6 GHz" etc. is used in this article, this term can generally represent frequencies that can be below 6 GHz, can be within FR1, or can include mid-band frequencies. In addition, unless otherwise specifically stated, it should be understood that if the term "millimeter wave" etc. is used in this article, this term can generally represent frequencies that can include mid-band frequencies, can be within FR2, FR4, FR4-a or FR4-1 and / or FR5, or can be within the EHF band. It is envisioned that the frequencies included in these operating bands (e.g., FR1, FR2, FR3, FR4, FR4-a, FR4-1, and / or FR5) can be modified, and the technologies described in this article apply to those modified frequency ranges.

[0046] In some aspects, UE 120 may include a communication manager 140. As described in more detail elsewhere herein, the communication manager 140 may receive information associated with a first transmit power of a first carrier in an identified band and a second transmit power of a second carrier in the band, where the first transmit power and the second transmit power exceed a per-carrier group power threshold; and transmit at least one of a first communication using a first scaled transmit power or a second communication using a second scaled transmit power, where at least one of the first transmit power or the second transmit power is scaled in combination with the per-carrier group power threshold to form the first scaled transmit power or the second scaled transmit power. Additionally or alternatively, the communication manager 140 may perform one or more other operations described herein.

[0047] In some aspects, network node 110 may include a communication manager 150. As described in more detail elsewhere herein, the communication manager 150 may send information associated with a first transmit power of a first carrier in an identified band and a second transmit power of a second carrier in the band, where the sum of the first transmit power and the second transmit power exceeds a per-carrier group power threshold; and receive at least one of a first communication using a first scaled transmit power or a second communication using a second scaled transmit power, where at least one of the first transmit power or the second transmit power is scaled in combination with the per-carrier group power threshold to form the first scaled transmit power or the second scaled transmit power. Additionally or alternatively, the communication manager 150 may perform one or more other operations described herein.

[0048] As indicated above, Figure 1 is provided as an example. Other examples may differ from the example described with respect to Figure 1 that is described.

[0049] Figure 2 FIG. 200 is a diagram illustrating Example 200 of communication between network node 110 and UE 120 in wireless network 100 in accordance with the present disclosure. Network node 110 may be equipped with a set of antennas 234a through 234t, such as T antennas (T≥1). UE 120 may be equipped with a set of antennas 252a through 252r, such as R antennas (R≥1). Network node 110 of Example 200 includes one or more radio frequency components, such as antenna 234 and modem 254. In some examples, network node 110 may include an interface, a communication component, or another component that facilitates communication with UE 120 or another network node. Some network nodes 110 may not include radio frequency components that facilitate direct communication with UE 120, such as one or more CUs or one or more DUs.

[0050] At network node 110, transmit processor 220 may receive data destined for UE 120 (or a set of UEs 120) from data source 212. Transmit processor 220 may select one or more modulation and coding schemes (MCSs) for UE 120 at least in part based on one or more channel quality indicators (CQIs) received from UE 120. Network node 110 may process (e.g., encode and modulate) the data for UE 120 at least in part based on the MCS selected for UE 120 and may provide data symbols for UE 120. Transmit processor 220 may process system information (e.g., for semi-static resource allocation information (SRPI)) and control information (e.g., CQI requests, grants, and / or upper layer signaling) and may provide overhead symbols and control symbols. Transmit processor 220 may generate reference symbols for reference signals (e.g., cell-specific reference signal (CRS) or demodulation reference signal (DMRS)) and synchronization signals (e.g., primary synchronization signal (PSS) or secondary synchronization signal (SSS)). Transmit (TX) multiple-input multiple-output (MIMO) processor 230 may perform spatial processing (e.g., precoding) on the data symbols, control symbols, overhead symbols, and / or reference symbols, if applicable, and may provide a set of output symbol streams (e.g., T output symbol streams) to a corresponding set of modems 232 (e.g., T modems) (shown as modems 232a through 232t). For example, each output symbol stream may be provided to a modulator component (shown as MOD) of modem 232. Each modem 232 may process the corresponding output symbol stream (e.g., for OFDM) using the respective modulator component to obtain an output sample stream. Each modem 232 may also process the output sample stream (e.g., convert to analog, amplify, filter, and / or up-convert) using the respective modulator component to obtain a downlink signal. Modems 232a through 232t may transmit a set of downlink signals (e.g., T downlink signals) via a corresponding set of antennas 234 (e.g., T antennas) (shown as antennas 234a through 234t).

[0051] At the UE 120, a set of antennas 252 (shown as antennas 252a through 252r) may receive downlink signals from the network node 110 and / or other network nodes 110 and may provide a set of received signals (e.g., R received signals) to a set of modems 254 (e.g., R modems) (shown as modems 254a through 254r). For example, each received signal may be provided to a demodulator component (shown as DEMOD) of the modem 254. Each modem 254 may use the corresponding demodulator component to condition (e.g., filter, amplify, down-convert, and / or digitize) the received signal to obtain input samples. Each modem 254 may use the demodulator component to further process the input samples (e.g., for OFDM) to obtain received symbols. The MIMO detector 256 may obtain the received symbols from the modems 254, may perform MIMO detection on the received symbols if applicable, and may provide the detected symbols. The receive processor 258 may process (e.g., demodulate and decode) the detected symbols, may provide the decoded data for the UE 120 to the data sink 260, and may provide the decoded control information and system information to the controller / processor 280. The term "controller / processor" may refer to one or more controllers, one or more processors, or a combination thereof. The channel processor may determine reference signal received power (RSRP) parameters, received signal strength indicator (RSSI) parameters, reference signal received quality (RSRQ) parameters, and / or CQI parameters, etc. In some examples, one or more components of the UE 120 may be included in the housing 284.

[0052] The network controller 130 may include a communication unit 294, a controller / processor 290, and a memory 292. The network controller 130 may include, for example, one or more devices in a core network. The network controller 130 may communicate with the network node 110 via the communication unit 294.

[0053] One or more antennas (e.g., antennas 234a through 234t and / or antennas 252a through 252r) may include one or more antenna panels, one or more antenna groups, one or more sets of antenna elements, and / or one or more antenna arrays, etc., or may be included within one or more antenna panels, one or more antenna groups, one or more sets of antenna elements, and / or one or more antenna arrays, etc. The antenna panel, antenna group, set of antenna elements, and / or antenna array may include one or more antenna elements (within a single housing or multiple housings), a set of coplanar antenna elements, a set of non-coplanar antenna elements, and / or one or more antenna elements coupled to one or more transmit and / or receive components (such as Figure 2 one or more components in

[0054] On the uplink, at the UE 120, the transmit processor 264 may receive and process data from the data source 262 and control information from the controller / processor 280 (e.g., for reporting including RSRP, RSSI, RSRQ, and / or CQI). The transmit processor 264 may generate reference symbols for one or more reference signals. The symbols from the transmit processor 264 may be pre-coded by the TX MIMO processor 266 when applicable, further processed by the modem 254 (e.g., for DFT-s-OFDM or CP-OFDM), and transmitted to the network node 110. In some examples, the modem 254 of the UE 120 may include a modulator and a demodulator. In some examples, the UE 120 includes a transceiver. The transceiver may include any combination of the antenna 252, the modem 254, the MIMO detector 256, the receive processor 258, the transmit processor 264, and / or the TX MIMO processor 266. The transceiver may be used by a processor (e.g., the controller / processor 280) and the memory 282 to perform aspects of any of the methods described herein (e.g., reference Figures 7A to 11 ).

[0055] At the network node 110, the uplink signals from the UE 120 and / or other UEs may be received by the antenna 234, processed by the modem 232 (e.g., the demodulator component (shown as DEMOD) of the modem 232), detected by the MIMO detector 236 when applicable, and further processed by the receive processor 238 to obtain the decoded data and control information transmitted by the UE 120. The receive processor 238 may provide the decoded data to the data sink 239 and the decoded control information to the controller / processor 240. The network node 110 may include a communication unit 244 and may communicate with the network controller 130 via the communication unit 244. The network node 110 may include a scheduler 246 to schedule one or more UEs 120 for downlink communication and / or uplink communication. In some examples, the modem 232 of the network node 110 may include a modulator and a demodulator. In some examples, the network node 110 includes a transceiver. The transceiver may include any combination of the antenna 234, the modem 232, the MIMO detector 236, the receive processor 238, the transmit processor 220, and / or the TX MIMO processor 230. The transceiver may be used by a processor (e.g., the controller / processor 240) and the memory 242 to perform aspects of any of the methods described herein (e.g., reference Figures 7A to 11 ).

[0056] The controller / processor 240 of network node 110, the controller / processor 280 of UE 120, and / or Figure 2 any other component of may perform one or more techniques associated with power control for carrier aggregation and dual-connectivity operations, as described in more detail elsewhere herein. For example, the controller / processor 240 of network node 110, the controller / processor 280 of UE 120, and / or Figure 2 any other component of may perform or direct the operation of, for example Figure 8 process 800 of, Figure 9 process 900 of, and / or other processes as described herein. The memories 242 and 282 may store data and program code for network node 110 and UE 120, respectively. In some examples, memories 242 and / or 282 may include non-transitory computer-readable media storing one or more instructions for wireless communication (e.g., code and / or program code). For example, when the one or more instructions are executed by one or more processors of network node 110 and / or UE 120 (e.g., executed directly, or after compilation, transformation, and / or interpretation), the one or more processors, UE 120, and / or network node 110 may perform or direct the operation of, for example Figure 8 process 800 of, Figure 9 process 900 of, and / or other processes as described herein. In some examples, executing the instructions may include running the instructions, transforming the instructions, compiling the instructions, and / or interpreting the instructions, etc.

[0057] In some aspects, UE 120 includes components for receiving information associated with a first transmit power of a first carrier in an identified frequency band and a second transmit power of a second carrier in the frequency band, where the first transmit power and the second transmit power exceed a per-carrier-group power threshold; and / or components for transmitting at least one of a first communication using a first scaled transmit power or a second communication using a second scaled transmit power, where at least one of the first transmit power or the second transmit power is scaled in combination with the per-carrier-group power threshold to form the first scaled transmit power or the second scaled transmit power. The components for UE 120 to perform the operations described herein may include, for example, one or more of communication manager 140, antenna 252, modem 254, MIMO detector 256, receive processor 258, transmit processor 264, TX MIMO processor 266, controller / processor 280, or memory 282.

[0058] In some aspects, network node 110 includes components for sending information associated with a first transmit power of a first carrier and a second transmit power of a second carrier in an identification band, where the sum of the first transmit power and the second transmit power exceeds a per-carrier group power threshold; and / or components for receiving at least one of a first communication using a first scaled transmit power or a second communication using a second scaled transmit power, where at least one of the first transmit power or the second transmit power is scaled to the first scaled transmit power or the second scaled transmit power, respectively, in combination with the per-carrier group power threshold. Components for enabling network node 110 to perform the operations described herein may include, for example, one or more of communication manager 150, transmit processor 220, TX MIMO processor 230, modem 232, antenna 234, MIMO detector 236, receive processor 238, controller / processor 240, memory 242, or scheduler 246.

[0059] While Figure 2 the boxes in are illustrated as different components, the functions described above for these boxes may be implemented in a single hardware, software, or combined component or in various combinations of components. For example, the functions described for transmit processor 264, receive processor 258, and / or TX MIMO processor 266 may be performed by or under the control of controller / processor 280.

[0060] As indicated above, Figure 2 is provided as an example. Other examples may be different from the examples described with respect to Figure 2

[0061] The deployment of a communication system, such as a 5G NR system, can be arranged in various ways with various components or constituent parts. In a 5G NR system or network, network nodes, network entities, mobility elements of the network, RAN nodes, core network nodes, network elements, base stations, or network equipment may be implemented in an aggregated or disaggregated architecture. For example, a base station, such as a Node B (NB), evolved NB (eNB), NR BS, 5G NB, access point (AP), TRP, or cell, etc., or one or more units (or one or more components) performing base station functionality may be implemented as an aggregated base station (also referred to as a stand-alone base station or monolithic base station) or a disaggregated base station. A "network entity" or "network node" may refer to a disaggregated base station or one or more units of a disaggregated base station, such as one or more CUs, one or more DUs, one or more RUs, or a combination thereof.

[0062] ​A centralized base station (e.g., a centralized network node) may be configured to utilize a radio protocol stack that is physically or logically integrated within a single RAN node (e.g., within a single device or unit). A split base station (e.g., a split network node) may be configured to utilize a protocol stack that is physically or logically distributed between two or more units (such as one or more CUs, one or more DUs, or one or more RUs). In some examples, a CU may be implemented within a network node, and one or more DUs may be co-located with the CU, or alternatively, may be geographically or virtually distributed across one or more other network nodes. A DU may be implemented to communicate with one or more RUs. Each of the CU, DU, and RU may also be implemented as a virtual unit, such as a virtual central unit (VCU), a virtual distributed unit (VDU), or a virtual radio unit (VRU), etc.

[0063] Base station types of operations or network designs may consider the aggregation characteristics of base station functionality. For example, split base stations may be utilized in an IAB network, an open radio access network (O-RAN (such as a network configuration initiated by the O-RAN Alliance)), or a virtualized radio access network (vRAN, also known as a cloud radio access network (C-RAN)) to facilitate the scaling of a communication system by separating base station functionality into one or more units that can be deployed separately. A split base station may include functionality implemented across two or more units at various physical locations, as well as functionality implemented virtually for at least one unit, which can achieve flexibility in network design. Each unit of a split base station may be configured for wired or wireless communication with at least one other unit of the split base station.

[0064] Figure 3 FIG. is an illustration of an example split base station architecture 300 in accordance with the present disclosure. The split base station architecture 300 may include a CU 310 that may communicate directly with a core network 320 via a backhaul link, or indirectly with the core network 320 through one or more split control units (such as a near RT RIC 325 via an E2 link, or a non-RT RIC 315 associated with a service management and orchestration (SMO) framework 305, or both). The CU 310 may communicate with one or more DUs 330 via respective midhaul links (such as through an F1 interface). Each DU among the DUs 330 may communicate with one or more RUs 340 via a respective fronthaul link. Each RU among the RUs 340 may communicate with one or more UEs 120 via a respective radio frequency (RF) access link. In some embodiments, a UE 120 may be served simultaneously by multiple RUs 340.

[0065] Each unit in the unit (including CU 310, DU 330, RU 340) and the near RT RIC 325, non-RT RIC 315, and SMO framework 305 may include one or more interfaces or be coupled to one or more interfaces, and the one or more interfaces are configured to receive or transmit signals, data, or information (collectively referred to as signals) via a wired or wireless transmission medium. Each unit in the unit or the associated processor or controller that provides instructions to one or more communication interfaces of the corresponding unit may be configured to communicate with one or more units in other units via the transmission medium. In some examples, each unit in the unit may include a wired interface and a wireless interface. The wired interface is configured to receive signals or transmit signals to one or more units in other units via a wired transmission medium. The wireless interface may include a receiver, a transmitter, or a transceiver (such as an RF transceiver), and the wireless interface is configured to receive signals or transmit signals to one or more units in other units via a wireless transmission medium or perform both.

[0066] In some aspects, CU 310 may host one or more higher-layer control functions. Such control functions may include radio resource control (RRC) functions, packet data convergence protocol (PDCP) functions, or service data adaptation protocol (SDAP) functions, etc. Each control function may be implemented using an interface that is configured to convey signals to other control functions hosted by CU 310. CU 310 may be configured to handle user plane functionality (e.g., central unit-user plane (CU-UP) functionality), control plane functionality (e.g., central unit-control plane (CU-CP) functionality), or a combination thereof. In some specific implementations, CU 310 may be logically split into one or more CU-UP units and one or more CU-CP units. When implemented in an O-RAN configuration, the CU-UP units may communicate bidirectionally with the CU-CP units via an interface (such as an E1 interface). As needed, CU 310 may be implemented to communicate with DU 330 for network control and signaling.

[0067] Each DU 330 may correspond to a logical unit that includes one or more base station functions for controlling the operation of one or more RUs 340. In some aspects, the DU 330 may host one or more of the radio link control (RLC) layer, the MAC layer, and one or more high physical (PHY) layers at least partially according to a functional split (such as the functional split defined by 3GPP). In some aspects, one or more high PHY layers may be implemented by one or more modules for forward error correction (FEC) encoding and decoding, scrambling, and modulation and demodulation, etc. In some aspects, the DU 330 may further host one or more low PHY layers, such as one or more modules for fast Fourier transform (FFT), inverse FFT (iFFT), digital beamforming, or physical random access channel (PRACH) extraction and filtering, etc. Each layer (which may also be referred to as a module) may be implemented using an interface configured to communicate signals with other layers (and modules) hosted by the DU 330 or with control functions hosted by the CU 310.

[0068] Each RU 340 may implement lower layer functionality. In some deployments, the RU 340 controlled by the DU 330 may correspond to a logical node that hosts RF processing functions or low PHY layer functions, such as performing FFT, performing iFFT, digital beamforming, or PRACH extraction and filtering, etc., based on a functional split (e.g., the functional split defined by 3GPP) such as a lower layer functional split. In such an architecture, each RU 340 may be operated to handle over-the-air (OTA) communication with one or more UEs 120. In some embodiments, the real-time and non-real-time aspects of communicating with the control plane and user plane of the RU 340 may be controlled by the corresponding DU 330. In some scenarios, this configuration may enable each DU 330 and CU 310 to be implemented in a cloud-based RAN architecture such as a vRAN architecture.

[0069] The SMO framework 305 can be configured to support the RAN deployment and orchestration of non-virtualized network elements and virtualized network elements. For non-virtualized network elements, the SMO framework 305 can be configured to support the deployment of dedicated physical resources for RAN coverage requirements, and these dedicated physical resources can be managed via operation and maintenance interfaces (such as the O1 interface). For virtualized network elements, the SMO framework 305 can be configured to interact with a cloud computing platform (such as the Open Cloud (O-Cloud) platform 390) to perform network element lifecycle management (such as instantiating virtualized network elements) via a cloud computing platform interface (such as the O2 interface). Such virtualized network elements can include, but are not limited to, CU 310, DU 330, RU 340, non-RT RIC 315, and near-RT RIC 325. In some specific implementations, the SMO framework 305 can communicate with the hardware aspect of the 4G RAN (such as the Open eNB (O-eNB) 311) via the O1 interface. Additionally, in some specific implementations, the SMO framework 305 can directly communicate with each RU in one or more RUs 340 via the corresponding O1 interface. The SMO framework 305 can also include a non-RT RIC 315 configured to support the functionality of the SMO framework 305.

[0070] The non-RT RIC 315 can be configured to include logical functions that can enable non-real-time control and optimization of RAN elements and resources, artificial intelligence / machine learning (AI / ML) workflows including model training and updating, or policy-based guidance of applications / features in the near-RT RIC 325. The non-RT RIC 315 can be coupled to or communicate with the near-RT RIC 325 (such as via the A1 interface). The near-RT RIC 325 can be configured to include logical functions that can enable near-real-time control and optimization of RAN elements and resources through an interface (such as via the E2 interface) via data collection and actions, and this interface connects one or more CUs 310, one or more DUs 330, or both, and the O-eNB to the near-RT RIC 325.

[0071] In some specific implementations, to generate the AI / ML models to be deployed in the near-RT RIC 325, the non-RT RIC 315 may receive parameters or external enrichment information from an external server. Such information can be utilized by the near-RT RIC 325 and can be received from non-network data sources or from network functions at the SMO framework 305 or the non-RT RIC 315. In some examples, the non-RT RIC 315 or the near-RT RIC 325 may be configured to tune RAN behavior or performance. For example, the non-RT RIC 315 may monitor long-term trends and patterns of performance and employ an AI / ML model to perform corrective actions via the SMO framework 305 (such as reconfiguration via the O1 interface) or via the creation of RAN management policies (such as A1 interface policies).

[0072] As indicated above, Figure 3 is provided as an example. Other examples may be different from the examples described with respect to Figure 3 which are different from the examples described with respect to

[0073] Figure 4 is a diagram illustrating Example 400 of carrier aggregation according to the present disclosure.

[0074] Carrier aggregation is a technique that enables two or more component carriers (CCs, sometimes referred to as carriers) to be combined (e.g., combined into a single channel) for a single UE 120 to enhance data capacity. As shown, carriers can be combined in the same or different frequency bands. Additionally or alternatively, contiguous or non-contiguous carriers can be combined. The network node 110 can configure carrier aggregation for the UE 120 (such as in a radio resource control (RRC) message, downlink control information (DCI), and / or another signaling message).

[0075] As indicated by reference numeral 405, in some examples, carrier aggregation can be configured in an in-band contiguous mode, in which the aggregated carriers are contiguous with each other and in the same frequency band. As indicated by reference numeral 410, in some examples, carrier aggregation can be configured in an in-band non-contiguous mode, in which the aggregated carriers are non-contiguous with each other and in the same frequency band. As indicated by reference numeral 415, in some examples, carrier aggregation can be configured in an inter-band non-contiguous mode, in which the aggregated carriers are non-contiguous with each other and in different frequency bands.

[0076] In carrier aggregation, the UE 120 may be configured with a primary carrier or primary cell (PCell) and one or more secondary carriers or secondary cells (SCell). In some examples, the primary carrier may carry control information (e.g., downlink control information and / or scheduling information) for scheduling data communication on one or more secondary carriers, and such scheduling may be referred to as cross-carrier scheduling. In some examples, a carrier (e.g., a primary carrier or a secondary carrier) may carry control information for scheduling data communication on that carrier, and such scheduling may be referred to as self-carrier scheduling or carrier self-scheduling.

[0077] As indicated above, Figure 4 is provided as an example. Other examples may differ from the examples described with respect to Figure 4 what is described.

[0078] Figure 5 is a diagram illustrating Example 500 of dual connectivity according to the present disclosure. Figure 5 The example shown is for the Evolved Universal Mobile Telecommunications System Terrestrial Radio Access (E-UTRA)-NR dual connectivity (ENDC) mode. In the ENDC mode, the UE 120 communicates using the LTE RAT on the master cell group (MCG), and the UE 120 communicates using the NR RAT on the secondary cell group (SCG). Some example deployments of dual connectivity may include the ENDC mode (e.g., where the MCG is associated with the LTE RAT and the SCG is associated with the NR RAT), the NR-E-UTRA dual connectivity (NEDC) mode (e.g., where the MCG is associated with the NR RAT and the SCG is associated with the LTE RAT), the NR dual connectivity (NRDC) mode (e.g., where the MCG is associated with the NR RAT and the SCG is also associated with the NR RAT), or another dual connectivity mode (e.g., where the MCG is associated with a first RAT and the SCG is associated with one of the first RAT or a second RAT). The ENDC mode is sometimes referred to as the NR or 5G non-standalone (NSA) mode. Thus, as used herein, "dual connectivity mode" may refer to the ENDC mode, the NEDC mode, the NRDC mode, and / or another type of dual connectivity mode.

[0079] As Figure 5 shown, the UE 120 may communicate with both an eNB (e.g., a 4G network node 110) and a gNB (e.g., a 5G network node 110), and the eNB and the gNB may communicate (e.g., directly or indirectly) with a 4G / LTE core network (shown as including an Evolved Packet Core (EPC) including a Mobility Management Entity (MME), a Packet Data Network Gateway (PGW), a Serving Gateway (SGW), and / or other devices). In Figure 5Among them, the PGW and the SGW are collectively referred to as the P / SGW. In some examples, the eNB and the gNB may be co-located at the same network node 110. In some examples, the eNB and the gNB may be included in different network nodes 110 (for example, they may not be co-located).

[0080] As Figure 5 As further shown, in some examples, a wireless network that allows operation in 5G NSA mode may allow such operation using a master cell group (MCG) for a first RAT (for example, LTE RAT or 4G RAT) and a secondary cell group (SCG) for a second RAT (for example, NR RAT or 5G RAT). In this case, the UE 120 may communicate with the eNB via the MCG and may communicate with the gNB via the SCG. In some examples, the MCG may anchor the network connection between the UE 120 and the 4G / LTE core network (for example, for mobility, coverage, and / or control plane information), and the SCG may be added as an additional carrier to increase throughput (for example, for data traffic and / or user plane information). In some examples, the gNB and the eNB may not transfer user plane information between each other. In some examples, the UE 120 operating in dual-connectivity mode may be concurrently connected to an LTE network node 110 (for example, eNB) and an NR network node 110 (for example, gNB) (for example, in the case of ENDC or NEDC), or may be concurrently connected to one or more network nodes 110 using the same RAT (for example, in the case of NRDC). In some examples, the MCG may be associated with a first frequency band (for example, a sub-6 GHz band and / or an FR1 band), and the SCG may be associated with a second frequency band (for example, a millimeter wave band and / or an FR2 band).

[0081] UE 120 can communicate via the MCG and SCG using one or more radio bearers, such as data radio bearers (DRBs) and / or signaling radio bearers (SRBs). For example, UE 120 can send or receive data using one or more DRBs via the MCG and / or SCG. Similarly, UE 120 can use one or more SRBs to send or receive control information (e.g., radio resource control (RRC) information and / or measurement reports). In some examples, a radio bearer can be dedicated to a specific cell group (e.g., the radio bearer can be an MCG bearer or an SCG bearer). In some examples, a radio bearer can be a split radio bearer. A split radio bearer can be split in the uplink and / or downlink. For example, a DRB can be split in the downlink (e.g., UE 120 can receive downlink information for the MCG or SCG in the DRB) but not split in the uplink (e.g., the uplink may not be split from the main path to the MCG or SCG, such that UE 120 only transmits in the uplink on the main path). In some examples, a DRB can be split in the uplink, with a main path to the MCG or SCG. A DRB split in the uplink can use the main path to send data until the size of the uplink transmit buffer meets the uplink data split threshold. If the uplink transmit buffer meets the uplink data split threshold, UE 120 can use the DRB to send data to the MCG or SCG.

[0082] As indicated above, Figure 5 is provided as an example. Other examples may differ from the examples described with respect to Figure 5 which are described.

[0083] Figure 6 is a diagram illustrating Example 600 of power control in accordance with the present disclosure.

[0084] As Figure 6 shown, in carrier aggregation or dual connectivity, a UE can be configured for communication on a set of carriers CC1, CC2, and CC3. Each carrier can have a separate maximum transmit power P CMAX,f,c . For each carrier, the UE determines the transmit power such that the transmit power on that carrier does not exceed the maximum transmit power. In other words, as shown in the figure, the UE can calculate the transmit power on CC1 and CC3 that exceeds P CMAX,f,c , and accordingly reduce the calculated transmit power such that the reduced transmit power does not exceed P CMAX,f,c . On CC2, the UE calculates that the transmit power does not exceed P CMAX,f,c, so it does not reduce the calculated transmission power on CC2. After ensuring that each carrier does not exceed the corresponding maximum transmission power (e.g., the maximum transmission power may be different or the same on each carrier), the UE determines whether the total transmission power across these carriers (e.g., for concurrent transmissions) exceeds the total maximum transmission power P CMAX . If P CMAX is exceeded on all carriers (or a subset of carriers, such as all carriers on FR1 or all carriers on FR2), the UE may perform power scaling to ensure that the transmissions on multiple carriers do not exceed the total maximum transmission power. In some examples, the UE may perform power scaling according to priorities. For example, when the total transmission power across all carriers in a frequency band (such as FR1 or FR2) exceeds the total maximum power P CMAX , the UE may allocate the available transmission power to the uplink transmissions according to the priority order so that the total power does not exceed P CMAX .

[0085] As indicated above, Figure 6 is provided as an example. Other examples may be different from the examples described with respect to Figure 6 .

[0086] For inter-band and intra-band uplink carrier aggregation or dual connectivity, the UE ensures that the transmission power of each carrier does not exceed the per-carrier limit (e.g., the power class P CMAX,f,c ) of the carrier, and the total transmission power across all carriers in multiple frequency bands does not exceed the per-carrier aggregation limit (e.g., the power class of carrier aggregation). However, the UE may not be configured to adjust the transmission power such that the total transmission power of the carriers in a single frequency band does not exceed the per-band limit (e.g., the power class of the frequency band). In other words, when the first frequency band includes a first set of carriers and the second frequency band includes a second set of carriers, the total transmission power of the first set of carriers and the second set of carriers may not exceed the cross-band maximum, but for example, only the total transmission power of the first set of carriers may exceed the single-band maximum. Additionally, in some scenarios, the cross-band maximum may be exceeded without negatively affecting the communication.

[0087] Some aspects described herein implement power control for carrier aggregation and dual connectivity. For example, the UE may be configured with power handling procedures for intra-band and inter-band power control (e.g., to avoid exceeding the intra-band maximum transmission power threshold and / or the inter-band maximum transmission power threshold). In this case, the UE may apply scaling to the calculated transmission power to determine the scaled transmission power, which, for example, jointly does not exceed the power maximum, such as the intra-band power maximum. In this way, the UE may optimize the available transmission power while complying with the established transmission power maximums to avoid negative impacts on the communication, such as avoiding interference.

[0088] Figures 7A to 7Fis a diagram illustrating example 700 associated with power control for carrier aggregation and dual connectivity operations according to the present disclosure. As Figure 7A shown, example 700 includes communication between network node 110 and UE 120.

[0089] As in Figure 7A and further illustrated by reference numeral 710, UE 120 may receive configuration information and / or scheduling information. For example, UE 120 may receive configuration information identifying one or more transmit power thresholds, as described herein. Additionally or alternatively, UE 120 may receive information associated with scheduling a set of transmissions, such as information identifying a set of carriers, information identifying a resource set on the set of carriers, information triggering a transmission on the set of resources, or information identifying a transmit power for the transmission, etc.

[0090] As in Figure 7A and further illustrated by reference numerals 720 and 730, UE 120 may calculate one or more transmit powers and may scale one or more transmit powers (or subsets thereof). For example, UE 120 may calculate a first transmit power for transmitting a first communication on a first carrier in a frequency band and a second transmit power for transmitting a second communication on a second carrier in the frequency band. In this case, the sum of the first transmit power and the second transmit power may exceed the transmit power threshold for the frequency band, which may trigger UE 120 to scale the first transmit power, the second transmit power, or both the first transmit power and the second transmit power to avoid exceeding the transmit power threshold.

[0091] In some aspects, UE 120 may determine whether the total power of the uplink carriers in a frequency band exceeds the total power limit of the frequency band. For example, as in Figure 7B and illustrated by reference numeral 760, UE 120 may determine whether the total power of carrier 1 and carrier 2 on frequency band A exceeds the total power of frequency band A, and / or whether the total power of carrier 3 and carrier 4 on frequency band B exceeds the total power of frequency band B. In this case, UE 120 may scale or reduce the transmit power of one or more uplink carriers on the frequency band where the total power is exceeded. For example, when the total power of carrier 1 and 2 on frequency band A exceeds the maximum power of frequency band A, UE 120 may scale or reduce the first transmit power of carrier 1 and / or the second transmit power of carrier 2. Similarly (and independently), when the total power of carrier 3 and 4 on frequency band B exceeds the maximum power of frequency band B, UE 120 may scale or reduce the third transmit power of carrier 3 and / or the fourth transmit power of carrier 4. In other words, UE 120 may evaluate and scale frequency band A and frequency band B based on their respective maximum powers (e.g., rather than scaling the transmissions on frequency band A at least in part based on the power of the carriers on frequency band B).

[0092] In some aspects, the UE 120 may evaluate power based on another factor rather than based on frequency bands. For example, the UE 120 may group carriers and / or transmissions for power evaluation according to a frequency band group (e.g., a configured frequency band group of carriers that may or may not correspond to a single frequency band), according to a power amplifier (e.g., a configured group of carriers for transmission using a single amplifier), according to a transmission chain (e.g., a configured group of carriers for processing using a single transmission chain), or according to another factor. As shown in Figure 7B and illustrated by reference numeral 762, the first group includes carriers 1 and 2 of frequency band A and carrier 3 of frequency band B, and the second group includes carriers 4 and 5 of frequency band C and carrier 6 of frequency band D. The UE 120 may determine, for example, whether the total transmission power of carriers 1 to 3 exceeds the total transmission power of the first group and scale one or more of carriers 1 to 3 accordingly. Similarly (and independently), the UE 120 may determine whether carriers 4 to 6 exceed the total transmission power of the second group and scale one or more of carriers 4 to 6 accordingly. In this case, the network node 110 may indicate which carriers are grouped into a single group, which carriers are amplified using a single amplifier, or which carriers are processed using a single transmission chain. Additionally or alternatively, the UE 120 may indicate to the network node 110 information identifying which carriers are associated with a single group, amplifier, or transmission chain.

[0093] In some aspects, the UE 120 may use a power scaling process to scale the transmission power in a single frequency band or group. For example, the UE 120 may use a priority-based power scaling process, where the UE 120 allocates power to carriers based on the relative priorities of transmissions carried on different carriers, as described in more detail in 3GPP Technical Specification (TS) 38.213 regarding per-band power scaling. Additionally or alternatively, the UE 120 may use a different priority ordering to allocate transmission power, such as a priority ordering that includes giving priority to the primary cell (PCell), the primary secondary cell (PSCell), or the physical uplink control channel (PUCCH) secondary cell (SCell) (PUCCH-SCell) transmissions over other transmissions within the same frequency band or group. Additionally or alternatively, the UE 120 may allocate transmission power at least in part based on received configuration. For example, the UE 120 may receive information identifying an offset value between two carriers via radio resource control (RRC) signaling. In this case, the UE 120 may scale the transmission power such that the offset value between the carriers is maintained for the correspondingly scaled transmission power, as shown in Figure 7C and illustrated by reference numeral 764.

[0094] In some aspects, the UE 120 may determine whether multiple different types of power limits are exceeded. For example, as in Figure 7D and shown by reference numerals 766 and 768, the UE 120 may be configured with per-band power limits and per-band (e.g., FR1 or FR2) power limits, or may be configured with per-group power limits and per-band power limits. In such a case, the UE 120 may determine the scaled transmit power at least in part based on the multiple different types of power limits. For example, the UE 120 may perform power scaling within a band according to the per-band limit and then perform power scaling between bands according to the per-band limit. In such a case, the UE 120 determines the transmit power of each uplink carrier and scales each uplink carrier such that each uplink carrier does not exceed the maximum power P CMAX,f,c ; determines whether the total transmit power of the uplink carriers in a group or band exceeds the maximum transmit power of the group or band, and if so, scales the uplink carriers in the group or band; and determines whether the total power of the uplink carriers across groups or bands in a band (e.g., FR1 or FR2) exceeds the maximum transmit power of the band, and if so, scales the uplink carriers in the band. In some aspects, the UE 120 may determine the priority of a band or group and scale the transmit power of the band or group or its carriers at least in part based on the priority of the band or group. In some aspects, the UE 120 may use one scaling factor or a set of scaling factors to scale the transmit power of the carriers of a band or group. Additionally or alternatively, the UE 120 may discard one or more uplink transmissions on one or more uplink carriers at least in part based on the priority of one or more uplink transmissions.

[0095] Additionally or alternatively, the UE 120 may perform power scaling between frequency bands according to per-band limits and then perform power scaling within a frequency band according to per-band limits. In this case, the UE 120 may determine whether the maximum power of each frequency band or group is exceeded, and if so, scale the transmission power on the carriers in the frequency band or group; determine whether the transmission power of each uplink carrier exceeds the carrier transmission power, and if so, scale the transmission power on the carrier; and determine whether the total power of the uplink carriers across a group or frequency band exceeds the maximum transmission power of the group or frequency band, and if so, scale the uplink carriers in the group or frequency band. In some aspects, the UE 120 may determine the maximum transmission power of each frequency band or group at least in part based on a semi-static RRC configuration. Additionally or alternatively, the UE 120 may dynamically determine the maximum transmission power, such as at least in part based on whether resource reservation has been performed, which frequency bands or groups have uplink transmissions, or another factor. Although some aspects are described herein in terms of uplink carriers, the transmission power control described herein may be applicable to sidelink, downlink, or another link.

[0096] In some aspects, the UE 120 may perform power scaling for ENDC or NRDC mode. For example, the UE 120 may be configured for independent power control on different cell groups, such as independent power control for a master cell group (MCG) and for a secondary cell group (SCG). In this case, the MCG may be a first group with a first maximum transmission power P MCG and the SCG may be a second group with a second maximum transmission power P SCG , as shown in Figure 7E and illustrated by reference numeral 770. The UE 120 may determine whether the transmission powers of carrier 1 and carrier 2 in frequency band A of the MCG exceed P MCG , and if so, may scale one or more of these transmission powers to determine one or more scaled transmission powers such that the sum of all transmission powers on the MCG does not exceed P MCG . Additionally or alternatively, the UE 120 may determine whether the transmission powers of carriers 3 to 6 on frequency bands B and C exceed P SCG , and if so, may scale one or more of these transmission powers to determine one or more scaled transmission powers such that the sum of all transmission powers on the SCG does not exceed S SCG . Similarly, as shown in Figure 7Ein and shown by reference numeral 772, UE 120 may support inter-cell group (inter-CG) power sharing. This may occur when a frequency band or a packet includes carriers belonging to multiple CGs. In such a case, for the ENDC mode, UE 120 may perform dynamic power sharing for MCG carriers and SCG carriers in the same frequency band or packet (e.g., carriers 3 and 4 in band B). Similarly, for the NRDC mode, UE 120 may perform semi-static power sharing between P MCG and P SCG for carriers in the same frequency band or group, or perform dynamic power sharing at least partially based on the MCG scheduling delay.

[0097] Figure 7F An example 774 of dynamic power sharing is shown. As shown, UE 120 may divide power between the MCG and the SCG at least partially based on a downlink control information (DCI) instruction. Here, for MCG uplink transmission, SCG transmission does not affect MCG uplink power control. Instead, for SCG uplink transmission, the maximum transmission power of the SCG is the smaller of P SCG and P 总 - P tot,MCG . In other words, UE 120 may determine the MCG transmission power at least partially based on the MCG DCI until time T 0 - T 偏移 . After time T 0 - T 偏移 , the network node 110 may avoid scheduling MCG uplink transmissions that overlap with the SCG start time T 0 . In other words, UE 120 performs unidirectional (MCG to SCG) power sharing for inter-CG power sharing. In some aspects, UE 120 may use priority ordering rules within each cell group, such as one or more of the priority ordering rules described above. In some aspects, UE 120 may report the value of T 偏移 as a capability indication so that the network node 110 can refrain from scheduling MCG uplink transmissions that overlap with the SCG start time T 0 . For example, UE 120 may report the maximum possible value among a set of minimum UE processing times across all serving cells in the MCG and the SCG as the value of T 偏移 . Additionally or alternatively, UE 120 may report the maximum possible value among the minimum UE processing times excluding the minimum processing time for channel state information (CSI) multiplexing .

[0098] Return Figure 7A, and as indicated by reference numeral 740, the UE 120 may transmit using a scaled transmit power. For example, the UE 120 may use a first scaled transmit power to transmit a first communication (on a first carrier) and a second scaled transmit power to transmit a second communication (on a second carrier). Additionally or alternatively, the UE 120 may use the first scaled transmit power to transmit the first communication and a second transmit power to transmit the second communication. Additionally or alternatively, the UE 120 may use a first transmit power to transmit the first communication and a second scaled transmit power to transmit the second communication. In other words, the UE 120 may use only scaled transmit power or a combination of scaled and unscaled transmit power. Additionally or alternatively, the UE 120 may discard the transmission of one or more communications on one or more carriers (e.g., abandon the transmission and use the resources assigned for transmitting another communication or allow the resources to be used by another wireless communication device).

[0099] As indicated above, Figures 7A to 7F is provided as an example. Other examples may be different from what is described with respect to Figures 7A to 7F what is described.

For example, the UE may (e.g., using Figure 10The communication manager 140 and / or the transmit component 1004 depicted therein transmits at least one of a first communication using a first scaled transmit power or a second communication using a second scaled transmit power, as described above.

[0114] Although Figure 8 example blocks of process 800 are shown, in some aspects, process 800 may include additional blocks, fewer blocks, different blocks, or blocks arranged in a different manner compared to those depicted. Additionally or alternatively, two or more blocks of process 800 may be executed in parallel. Figure 8 is a diagram illustrating an example process 900, such as may be performed by a network node, in accordance with the present disclosure. Example process 900 is an example in which a network node (e.g., network node 110) performs operations associated with power control for carrier aggregation and dual connectivity operations.

For example, a network node may (e.g., using the communication manager 150 and / or the receiving component 1102 depicted in FIG. Figure 11 ) receive at least one of a first communication using a first scaled transmit power or a second communication using a second scaled transmit power, as described above. In some aspects, at least one of the first transmit power or the second transmit power is scaled to the first scaled transmit power or the second scaled transmit power, respectively, in combination with a per-carrier-group power threshold.
