[0001] This patent application claims priority to U.S. Patent Application No. 18 / 610,991, filed March 20, 2024, entitled “USER EQUIPMENT INFORMATIONFOR ENHANCING MULTI-CARRIER COMMUNICATIONS”, assigned to the assignee of this application. The disclosure of the earlier application is considered part of this patent application and is incorporated herein by reference. Technical Field

[0002] All aspects of this disclosure relate to wireless communication in general, and more particularly to techniques, apparatus and methods for enhancing user equipment information for multi-carrier communication. Background Technology

[0003] Wireless communication systems are widely deployed to provide a variety of services, including voice, text, messaging, video, data, and / or other services. Services may include unicast, multicast, and / or broadcast services, etc. Typical wireless communication systems employ multiple access radio access technologies (RATs) capable of supporting communication with multiple users by sharing available system resources (e.g., time-domain resources, frequency-domain resources, spatial-domain resources, and / or device transmit power, etc.). Examples of such multiple access RATs 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.

[0004] The aforementioned Multiple Access RATs have been adopted in various telecommunications standards to provide a common protocol enabling different wireless communication devices to communicate at the city, national, regional, or global level. An example telecommunications standard is New Radio (NR). NR (also known as 5G) is part of the continuous evolution of mobile broadband announced by the 3rd Generation Partnership Project (3GPP). NR (and other mobile broadband evolutions beyond NR) can be designed to better support the Internet of Things (IoT) and reduced-capacity device deployments, industrial connectivity, millimeter-wave (mmWave) expansion, licensed and unlicensed spectrum access, non-terrestrial network (NTN) deployments, sidelinks and other device-to-device direct communication technologies (e.g., cellular vehicle-to-everything (CV2X) communications), massive MIMO, decomposed network architectures and network topology expansion, multi-subscriber implementations, high-precision positioning and / or radio frequency (RF) sensing, and more. As the demand for mobile broadband access continues to grow, further improvements to NR can be implemented, and other radio access technologies (such as 6G) can be introduced to further advance mobile broadband evolution.

[0031] Various aspects of this disclosure are described below with reference to the accompanying drawings. However, aspects of this disclosure may be embodied in many different forms and should not be construed as limited to any specific aspect illustrated or described with reference to the drawings or otherwise presented in this disclosure. Rather, these aspects are provided so that this disclosure will be comprehensive and complete, and will fully convey the scope of this disclosure to those skilled in the art. Those skilled in the art will understand that the scope of this disclosure is intended to cover any aspect of this disclosure disclosed herein, whether implemented independently of or in combination with any other aspect of this disclosure. For example, various combinations or numbers of aspects set forth herein may be used to implement an apparatus or a method of practice. Furthermore, the scope of this disclosure is intended to cover apparatuses having structures and / or functionalities other than those available for practicing the various aspects of this disclosure set forth herein, or methods of practice using those other structures and / or functionalities. Any aspect of this disclosure disclosed herein may be embodied by one or more elements of the claims.

[0032] Various methods, operations, apparatuses, and techniques will now be presented with reference to them. These methods, operations, apparatuses, and techniques will be described in detail below and illustrated in the accompanying drawings by various blocks, modules, components, circuits, steps, processes, or algorithms (collectively, “elements”). These elements may be implemented using hardware, software, or a combination of hardware and software. Whether these elements are implemented as hardware or software depends on the specific application and the design constraints imposed on the system as a whole.

[0033] User equipment (UE) can be configured for multi-carrier operation, such as carrier aggregation (CA) and dual connectivity (DC). CA is a multi-carrier operation mode that allows two or more component carriers (CCs) to be combined (e.g., combined into a single channel) to enhance data capacity for the UE. CCs can be combined in the same or different frequency bands. DC is a multi-carrier operation mode in which the UE can communicate with two network nodes to increase bandwidth and reduce service latency. One network node acts as the primary node (MN) and the other network node acts as the secondary node (SN). In DC, the MN can communicate with the UE via a primary cell group (MCG) that may include one or more serving cells (e.g., one or more CCs), and the SN can communicate with the UE via a secondary cell group (SCG) that may include one or more serving cells (e.g., one or more CCs).

[0034] DC (Distributed Cell Control) is widely used in scenarios where a single Distributed Unit (DU) cannot control the aggregated serving cell set, such as aggregation across frequency ranges with non-co-located deployments and / or different gNB decompositions (e.g., for FR1+FR2 CA). However, in some examples, assuming the same number of CCs are configured / activated for the UE in both CA and DC modes, CA may outperform DC. One reason CA may outperform DC is that in CA, a single Media Access Control (MAC) entity controls all downlink and uplink resources across the aggregated CCs. Therefore, leveraging channel condition-related feedback from the UE, the DU can make decisions that are likely optimal for coordinating resource management for downlink and uplink communications. In DC, each cell group (e.g., MCG and SCG) can be controlled by a separate DU. Although some coordination may exist between the MN and SN (e.g., to ensure configuration consistency with UE capabilities and measurements), each DU typically makes decisions regarding scheduling downlink and uplink communications solely based on local information associated with that DU. For example, in a scenario where the UE is configured with 4 CCs in CA, all 4 CCs are controlled by a single MAC entity. In this scenario, the DU knows the instantaneous link quality of the UE on each of the four CCs in both the downlink and uplink. In a scenario where the UE is configured with four CCs in the DC, two CCs are controlled by the MN and two CCs are controlled by the SN. The MN DU knows the link quality of the UE on each of its own two CCs in both the downlink and uplink, and the SN DU also knows the link quality of the UE on each of its own two CCs in both the downlink and uplink. However, the MN DU does not know the link quality of the UE on the two CCs belonging to the SN, and the SN DU does not know the link quality of the UE on the two CCs belonging to the MN.

[0035] In CA, DU can route data to or from the UE based on downlink and uplink channel estimates and Buffer State Reports (BSRs) across all logical channels, utilizing optimal link parameters. For example, if one CC is in a bad condition, all other three CCs can be used. In DC, for both downlink and uplink, data can be split across resources in the MCG and SCG based on Reference Signal Received Power (RSRP) and Total Available Bandwidth (BW). However, channel conditions are not considered when deciding whether the MCG and / or SCG should be used and how much resource at the MCG and / or SCG should be used.

[0036] The UE reports its capabilities for frequency band combinations supporting DC. However, aside from reporting UE capabilities, the UE may have minimal role in managing how CCs across MCGs and SCGs will use its resources (e.g., baseband resources, radio frequency (RF) chains, and / or antennas). Specifically, in certain situations, the UE may send UE Assistance Information (UAI) to request changes to some configurations, but the final decision rests solely with the network. The UE may only indicate a preference to reduce some configurations, and there is no mechanism for the UE to indicate whether it can perform further operations. The UE may indicate preferences individually for each cell group, but there is no joint indication that allows the UE to reduce the configuration set for one cell group while increasing the configuration set for another. Indications are carried via Radio Resource Control (RRC) signaling, and their transmission is subject to a prohibition timer. If the network grants permission, the changes will take a long time to take effect. Therefore, UAI cannot be used for rapid configuration adaptation.

[0037] For DC, the network decides how much data to pass through which cell group. When the available buffer space (BW) is small, the network uses both MCG and SCG to aggregate larger BWs and increase throughput. For the uplink, the network sets a data threshold to determine how much data to send on each cell group, and this data threshold depends on RSRP (e.g., UE location in the cell) and the total BW in the MCG and SCG. In DC, decisions about how resources should be used are made at a slower rate (e.g., relative to CA). MN and SN can evaluate the UE's RSRP (and possible exchange values). MN and SN can then determine the buffer threshold based solely on the total available BW in each cell group. However, from a data rate perspective, neglecting channel conditions in scheduling decisions across all resources in the MCG and SCG leads to suboptimal operating points, reduced throughput, and increased latency.

[0038] Various aspects as a whole relate to UE information used to enhance multi-carrier operation. Some aspects more specifically relate to considering channel conditions in decisions regarding splitting data volumes across MCGs and SCGs in a DC and / or allocating UE resources across MCGs and SCGs. As used herein, the term "data volume" may refer to a certain amount of data. In some aspects, the UE may send first information associated with splitting network resources across a first cell group and a second cell group and / or second information associated with sharing UE resources across a first cell group and a second cell group to at least one of a first network node or a second network node. For example, the first information may be associated with splitting data volumes across a first cell group and a second cell group. The UE may communicate via the first cell group and the second cell group based at least in part on the splitting of data volumes across the first cell group and the second cell group and / or at least in part on the allocation of UE resources across the first cell group and the second cell group based on the second information. In some aspects, the first information may be based at least in part on channel estimation of the CC of the first cell group and the second cell group, and the splitting of data volume across the first cell group and the second cell group may be determined at least in part based on the first information (e.g., by the UE or at least one of the first network node or the second network node). In some aspects, the second information may be based at least in part on channel estimation of the CC of the first cell group and the second cell group, and the allocation of UE resources across the first cell group and the second cell group may be determined based on the second information (e.g., by the UE or at least one of the first network node or the second network node).

[0039] Specific aspects of the subject matter described in this disclosure can be implemented to achieve one or more of the following potential advantages. In some examples, by splitting data volumes based on first information at least partially based on channel estimates of the first and second cell groups, the described techniques can be used to improve resource selection for downlink and uplink across MCGs and SCGs, resulting in increased downlink and uplink throughput and reduced latency in the DC. In some examples, by allocating UE resources based on second information at least partially based on channel estimates of the first and second cell groups, the described techniques can be used to improve and / or optimize downlink and uplink performance in each cell group. This can increase uplink and downlink throughput and reduce latency in the DC, and enhance network spectral efficiency and reduce network power consumption by preventing the network from allocating time-domain (TD) and / or frequency-domain (FD) resources to UEs with poor channel conditions on links when the UE can be served more efficiently on other links.

[0040] Multiple access radio access technology (RAT) has been adopted in various telecommunications standards to provide a common protocol that enables wireless communication devices to communicate at the city, enterprise, national, regional, or global level. For example, 5G New Radio (NR) is part of the continuous mobile broadband evolution announced by the 3rd Generation Partnership Project (3GPP). 5G NR supports a variety of technologies and use cases, including enhanced mobile broadband (eMBB), ultra-reliable low-latency communication (URLLC), massive machine-type communication (mMTC), millimeter wave (mmWave) technology, beamforming, network slicing, edge computing, Internet of Things (IoT) connectivity and management, and network function virtualization (NFV).

[0041] As the demand for broadband access increases and as the technologies supported by wireless communication networks evolve, further technological improvements can be adopted or implemented in 5G NR or future RATs (such as 6G) to further advance the evolution of wireless communication for a variety of existing and new use cases and applications. Such technological improvements can be associated with new frequency band extensions, licensed and unlicensed spectrum access, overlapping spectrum use, small cell deployments, non-terrestrial network (NTN) deployments, decomposed network architectures and network topology extensions, device aggregation, advanced duplex communication, sidelinks and other device-to-device direct communication, IoT (including passive or ambient IoT) networks, redcap UE functionality, industrial connectivity, multi-subscriber implementations, high-precision positioning, RF sensing and / or artificial intelligence or machine learning (AI / ML), and more. These technological improvements can support use cases such as wireless backhaul, wireless data centers, extended reality (XR) and metaverse applications, meta-services for supporting vehicle connectivity, holographic and mixed reality communications, autonomous and collaborative robots, vehicle platooning and collaborative manipulation, sensor networks, posture monitoring, brain-computer interfaces, digital twin applications, asset management, and general coverage applications using off-ground and / or aerial platforms, among others. The methods, operations, apparatuses, and techniques described herein can implement one or more of the foregoing technologies and / or support one or more of the foregoing use cases.

[0042] Figure 1 This is a diagram illustrating an example of a wireless communication network 100 according to the present disclosure. The wireless communication network 100 may be a 5G (or NR) network or a 6G network, or may include elements of a 5G (or NR) network or elements of a 6G network, etc. The wireless communication network 100 may include a plurality of network nodes 110, shown as network node (NN) 110a, network node 110b, network node 110c, and network node 110d. Network nodes 110 may support communication with a plurality of UEs 120 (shown as UE120a, UE 120b, UE 120c, UE 120d, and UE 120e).

[0043] Network nodes 110 and UEs 120 of wireless communication network 100 can communicate using the electromagnetic spectrum, which can be subdivided into various categories, frequency bands, carriers, and / or channels according to frequency or wavelength. For example, devices of wireless communication network 100 can communicate using one or more operating frequency bands. In some aspects, multiple wireless networks 100 can be deployed in a given geographical area. Each wireless communication network 100 can support a specific RAT (which may also be referred to as an air interface) and can operate on one or more carrier frequencies in one or more frequency ranges. Examples of RATs include 4G RATs, 5G / NRRATs, and / or 6G RATs, etc. In some examples, when multiple RATs are deployed in a given geographical area, each RAT in that geographical area can operate on a different frequency to avoid interference with each other.

[0044] Various operating frequency bands have been defined as frequency ranges designated FR1 (410 MHz to 7.125 GHz), FR2 (24.25 GHz to 52.6 GHz), FR3 (7.125 GHz to 24.25 GHz), FR4a or FR4-1 (52.6 GHz to 71 GHz), FR4 (52.6 GHz to 114.25 GHz), and FR5 (114.25 GHz to 300 GHz). Although a portion of FR1 is greater than 6 GHz, in some documents and articles, FR1 is often (interchangeably) referred to as the “sub-6 GHz” band. Similarly, in some documents and articles, FR2 is often (interchangeably) referred to as the “millimeter wave” band, but this is different from the Very High Frequency (EHF) band (30 GHz to 300 GHz) identified as the “millimeter wave” band by the International Telecommunication Union (ITU). The frequencies between FR1 and FR2 are often referred to as the mid-band frequencies, including FR3. Frequency bands falling within FR3 can inherit FR1 or FR2 characteristics, thereby effectively extending the characteristics of FR1 or FR2 into mid-band frequencies. Therefore, "below 6 GHz" (if used herein) can broadly refer to frequencies less than 6 GHz, within FR1, and / or included in mid-band frequencies. Similarly, the term "millimeter wave" (if used herein) can broadly refer to frequencies included in mid-band frequencies, within FR2, FR4, FR4-a, FR4-1, or FR5, and / or within the EHF band. Higher frequency bands can extend 5G NR operation, 6G operation, and / or other RATs above 52.6 GHz. For example, each of FR4a, FR4-1, FR4, and FR5 falls within the EHF band. In some examples, the wireless communication network 100 can implement dynamic spectrum sharing (DSS), where multiple RATs (e.g., 4G / LTE and 5G / NR) are implemented within a single frequency band using dynamic bandwidth allocation (e.g., based on user demand). It is conceivable that the frequencies included in these operating frequency bands (e.g., FR1, FR2, FR3, FR4, FR4-a, FR4-1 and / or FR5) can be modified, and the techniques described herein are applicable to those modified frequency ranges.

[0045] Network node 110 may include one or more devices, components, or systems that enable communication between UE 120 and one or more devices, components, or systems of wireless communication network 100. Network node 110 may be, may include, or may also be referred to as an NR network node, 5G network node, 6G network node, node B, eNB, gNB, access point (AP), transmit / receive point (TRP), mobility element, core, network entity, network element, network equipment, and / or another type of device, component, or system included in a radio access network (RAN).

[0046] Network node 110 may be implemented as a single physical node (e.g., a single physical structure) or as two or more physical nodes (e.g., two or more different physical structures). For example, network node 110 may be a device or system implementing a portion of a radio protocol stack, a device or system implementing a complete radio protocol stack (such as a complete gNB protocol stack), or a collection of devices or systems collectively implementing a complete radio protocol stack. For example, and as shown, network node 110 may be an aggregated network node (with an aggregated architecture), meaning that network node 110 can implement a complete radio protocol stack physically and logically integrated within a single node (e.g., a single physical structure) in the wireless communication network 100. For example, aggregated network node 110 may consist of a single standalone base station or a single TRP that uses the complete radio protocol stack to implement or facilitate communication between UE 120 and the core network of wireless communication network 100.

[0047] Alternatively, and also as shown in the figure, network node 110 can be a decomposed network node (sometimes referred to as a decomposed base station), meaning that network node 110 can realize a radio protocol stack that is physically distributed and / or logically distributed among two or more nodes in the same or different geographical locations. For example, a decomposed network node may have a decomposed architecture. In some deployments, decomposed network node 110 may be used in integrated access and backhaul (IAB) networks, in open radio access networks (O-RAN) (such as network configurations conforming to O-RAN Alliance standards), or in virtualized radio access networks (vRAN) (also referred to as cloud radio access networks (C-RAN)) to facilitate scaling by decomposing base station functionality into multiple units that can be deployed independently.

[0048] Network nodes 110 of wireless communication network 100 may include one or more central units (CUs), one or more distributed units (DUs), and / or one or more radio units (RUs). CUs may host one or more higher-layer control functions, such as RRC functions, Packet Data Convergence Protocol (PDCP) functions, and / or Service Data Adaptation Protocol (SDAP) functions, etc. DUs may host one or more of the Radio Link Control (RLC) layer, MAC layer, and / or one or more higher physical (PHY) layers, at least in part, according to functional splits (such as functional splits defined by 3GPP). In some examples, DUs may also host one or more lower PHY layer functions, such as Fast Fourier Transform (FFT), Inverse FFT (iFFT), beamforming, Physical Random Access Channel (PRACH) extraction and filtering, and / or scheduling of resources for one or more UEs 120, etc. RUs may host RF processing functions or lower PHY layer functions, such as FFT, iFFT, beamforming, or PRACH extraction and filtering, etc., according to functional splits (such as lower-layer functional splits). In this architecture, each RU can be operated to handle over-the-air (OTA) communications with one or more UE 120s.

[0049] In some aspects, a single network node 110 may include a combination of one or more CUs, one or more DUs, and / or one or more RUs. Additionally or alternatively, network node 110 may include one or more near real-time (near RT) RAN Intelligent Controllers (RICs) and / or one or more non-real-time (non-RT) RICs. In some examples, CUs, DUs, and / or RUs may be implemented as virtual units, such as Virtual Central Units (VCUs), Virtual Distributed Units (VDUs), or Virtual Radio Units (VRUs), etc. Virtual units may be implemented as virtual network functions, such as those associated with cloud deployments.

[0050] Some network nodes 110 (e.g., base stations, RUs, or TRPs) can provide communication coverage for a specific geographic area. In 3GPP, the term "cell" can refer to the coverage area of ​​network node 110 or to network node 110 itself, depending on the context in which the term is used. Network node 110 can support one or more (e.g., three) cells. In some examples, network node 110 can provide communication coverage for macro cells, pico cells, femto cells, or another type of cell. A macro cell can cover a relatively large geographic area (e.g., a radius of several kilometers) and can allow unrestricted access by UE 120 with a service subscription. A pico cell can cover a relatively small geographic area and can allow unrestricted access by UE 120 with a service subscription. A femto cell can cover a relatively small geographic area (e.g., a residential area) and can allow restricted access by UE 120 associated with that femto cell (e.g., UE 120 in a Closed Subscriber Group (CSG)). The network node 110 used for a macro cell can be referred to as a macro network node. Network node 110 used for a picocell may be referred to as a pico network node. Network node 110 used for a femtocell may be referred to as a femto network node or a home network node. In some examples, the cell may not necessarily be stationary. For example, the geographical area of ​​the cell may move depending on the location of the associated mobile network node 110 (e.g., a train, satellite base station, drone, or NTN network node).

[0051] The wireless communication network 100 can be a heterogeneous network, comprising different types of network nodes 110, such as macro network nodes, piconet nodes, femtonet nodes, relay network nodes, aggregation network nodes, and / or decomposition network nodes, etc. Figure 1 In the example shown, network node 110a can be a macro network node for macro cell 130a, network node 110b can be a pico network node for pico cell 130b, and network node 110c can be a femto network node for femto cell 130c. Various types of network nodes 110 can typically transmit at different power levels, serve different coverage areas, and / or have different effects on interference in the wireless communication network 100 compared to other types of network nodes 110. For example, macro network nodes can have high transmit power levels (e.g., 5 watts to 40 watts), while pico network nodes, femto network nodes, and relay network nodes can have lower transmit power levels (e.g., 0.1 watts to 2 watts).

[0052] In some examples, network node 110 may be, may include, or may operate as a RU, TRP, or base station communicating with one or more UEs 120 via a radio access link (which may be referred to as a "Uu" link). The radio access link may include a downlink and an uplink. "Downlink" (or "DL") refers to the communication direction from network node 110 to UE 120, and "uplink" (or "UL") refers to the communication direction from UE 120 to network node 110. Downlink channels may include one or more control channels and one or more data channels. Downlink control channels may be used to transmit downlink control information (DCI) (e.g., scheduling information, reference signals, and / or configuration information) from network node 110 to UE 120. Downlink data channels may be used to transmit downlink data (e.g., user data associated with UE 120) from network node 110 to UE 120. Downlink control channels may include one or more physical downlink control channels (PDCCH), and downlink data channels may include one or more physical downlink shared channels (PDSCH). The uplink channel may similarly include one or more control channels and one or more data channels. The uplink control channel can be used to transmit uplink control information (UCI) from UE 120 to network node 110 (e.g., transmitting corresponding reference signals and / or feedback with one or more downlinks). The uplink data channel can be used to transmit uplink data (e.g., user data associated with UE 120) from UE 120 to network node 110. The uplink control channel may include one or more physical uplink control channels (PUCCH), and the uplink data channel may include one or more physical uplink shared channels (PUSCH). The downlink and uplink may each include a set of resources on which network node 110 and UE 120 can communicate.

[0053] Downlink and uplink resources may include time-domain resources (frames, subframes, time slots, and / or symbols), frequency-domain resources (bands, component carriers, subcarriers, resource blocks, and / or resource elements), and / or spatial-domain resources (specific transmission directions and / or beam parameters). Frequency-domain resources in some bands may be subdivided into bandwidth portions (BWPs). A BWP may be a contiguous block of frequency-domain resources allocated to one or more UEs 120 (e.g., a contiguous block of resource blocks). A UE 120 may be configured with both an uplink BWP and a downlink BWP (where the uplink BWP and downlink BWP may be the same BWP or different BWPs). BWPs may be dynamically configured and / or reconfigured (e.g., by sending DCI configuration to one or more UEs 120 via network node 110), meaning that BWPs may be adjusted in real-time (or near real-time) based on changing network conditions in the wireless communication network 100 and / or based on the specific requirements of one or more UEs 120. This allows for more efficient use of available frequency domain resources in the wireless communication network 100, as fewer frequency domain resources can be allocated to the BWP for UE 120 (which reduces the number of frequency domain resources that UE 120 needs to monitor), thus allowing more frequency domain resources to be distributed across multiple UE 120s. Therefore, the BWP can also assist in the implementation of such UE 120s by facilitating the configuration of smaller bandwidths for communications performed by lower-capacity UE 120s.

[0054] As described above, in some aspects, the wireless communication network 100 may be an IAB network, may include an IAB network, or may be included in an IAB network. In an IAB network, at least one network node 110 is an anchor network node communicating with a core network. The anchor network node 110 may also be referred to as an IAB donor (or "IAB donor"). The anchor network node 110 may be connected to the core network via a wired backhaul link. For example, the Ng interface of the anchor network node 110 may terminate at the core network. Additionally or alternatively, the anchor network node 110 may be connected to one or more devices in the core network that provide core access and mobility management functions (AMF). An IAB network typically also includes multiple non-anchor network nodes 110, which may also be referred to as relay network nodes or simply IAB nodes (or "IAB-nodes"). Each non-anchor network node 110 can directly communicate with the anchor network node 110 via a wireless backhaul link to access the core network, or can indirectly communicate with the anchor network node 110 via one or more other non-anchor network nodes 110 and an associated wireless backhaul link forming a backhaul path to the core network. Some anchor network nodes 110 or other non-anchor network nodes 110 can also directly communicate with one or more UEs 120 via a wireless access link carrying access services. For example, network resources used for wireless communication (such as time resources, frequency resources, and / or spatial resources) can be shared between the access link and the backhaul link.

[0055] In some examples, any network node 110 relaying communication may be referred to as a relay network node, a relay station, or simply a repeater. A repeater may receive communications from an upstream station (e.g., another network node 110 or UE 120) and transmit communications to a downstream station (e.g., UE 120 or another network node 110). In this case, the wireless communication network 100 may include or be referred to as a "multi-hop network." Figure 1 In 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. Additionally or alternatively, UE 120 can be a relay station capable of relaying transmissions to or from other UE 120s, or can operate as such a relay station. UE 120 relaying communication can be referred to as a UE repeater or relay UE, etc.

[0056] UE 120 may be physically distributed throughout the wireless communication network 100, and each UE 120 may be stationary or mobile. UE 120 may be, may include, or may be included in the following: access terminal, another terminal, mobile station, or subscriber unit. UE 120 may be, or may include, a cellular phone (e.g., a smartphone), 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, an ultrabook, a medical device, a biometric device, a wearable device (e.g., a smartwatch, smart clothing, smart glasses, a smart wristband and / or smart jewelry (such as a smart ring or smart bracelet)), an entertainment device (e.g., a music device, a video device and / or a satellite radio), an XR device, a vehicle component or sensor, a smart meter or sensor, industrial manufacturing equipment, a Global Navigation Satellite System (GNSS) device (such as a Global Positioning System device or another type of positioning device), a UE function of a network node, and / or any other suitable device or function that can communicate via a wireless medium, or may be coupled to them.

[0057] UE 120 and / or network node 110 may include one or more chips, system-on-a-chip (SoC), chipsets, packages, or devices that individually or collectively constitute or include a processing system. The processing system includes processor (or “processing”) circuitry in the form of one or more processors, microprocessors, processing units (such as central processing units (CPUs), graphics processing units (GPUs), neural processing units (NPUs), and / or digital signal processors (DSPs)), processing blocks, application-specific integrated circuits (ASICs), programmable logic devices (PLDs) (such as field-programmable gate arrays (FPGAs)), or other discrete gate or transistor logic components or circuits (all of which are generally referred to herein individually as “processors” or collectively as “processors” or “processor circuitry”). One or more of these processors may be individually or collectively configured to perform the various functions or operations described herein. A group of processors that can be configured or configured to perform a set of functions may include a first processor that can be configured or configured to perform a first function in the set, and a second processor that can be configured or configured to perform a second function in the set, or may include the entire group of processors that are configured or configured to perform the set of functions.

[0058] The processing system may also include memory circuitry in the form of one or more memory devices, memory blocks, memory elements, or other discrete gate or transistor logic components or circuits, each of which may include tangible storage media such as random access memory (RAM) or read-only memory (ROM) or combinations thereof (all of which are generally referred to herein individually as "memory" or collectively as "memory" or "memory circuitry"). One or more of these memories may be coupled to one or more processors in the processor (e.g., operatively coupled, communicatively coupled, electronically coupled, or electrically coupled) and may store processor-executable code (such as software) individually or collectively, which, when executed by one or more processors in the processor, may configure one or more processors in the processor to perform the various functions or operations described herein. Additionally or alternatively, in some examples, one or more processors in the processor may be pre-configured to perform the various functions or operations described herein without being configured by software. The processing system may also include or be coupled to one or more modems (such as Wi-Fi (e.g., IEEE compliant) modems or cellular (e.g., 3GPP 4G LTE, 5G, or 6G compliant) modems). In some embodiments, one or more processors of the processing system include or implement one or more modems among the modems. The processing system may also include, or be coupled to, multiple radio components (collectively, “radio components”), multiple RF chains, or multiple transceivers, each of which may in turn be coupled to one or more antennas among multiple antennas. In some embodiments, one or more processors of the processing system include or implement one or more of the radio components, RF chains, or transceivers. UE 120 may include, or may be included in, a housing that accommodates components associated with UE 120, including the processing system.

[0059] Some UEs 120 may be considered Machine Type Communication (MTC) UEs, Evolved or Enhanced Machine Type Communication (eMTC) UEs, Further Enhanced eMTC (feMTC) UEs, or Enhanced feMTC (efeMTC) UEs, or further evolutions thereof, all of which may be referred to simply as "MTC UEs". MTC UEs may be, may include, or may be included in or coupled with the following: robots, unmanned aerial vehicles, remote devices, sensors, instruments, monitors, and / or location tags. Some UEs 120 may be considered IoT devices and / or may be implemented as NB-IoT (Narrowband IoT) devices. IoT UEs or NB-IoT devices may be, may include, or may be included in or coupled with the following: industrial machines, appliances, refrigerators, doorbell camera devices, home automation devices, and / or lighting fixtures, etc. Some UEs 120 may be considered customer premises equipment, which may include telecommunications equipment installed at a customer location (such as a home or office) to enable access to a service provider’s network (such as being included in or communicating with the wireless communication network 100).

[0060] Some UEs 120 can be categorized according to different categories associated with varying levels of complexity and / or capabilities. UEs 120 in the first category facilitate large-scale IoT within the wireless communication network 100 and offer lower complexity and / or cost compared to UEs 120 in the second category. UEs 120 in the second category may include mission-critical IoT devices capable of URLLC, enhanced mobile broadband (eMBB), and / or precise positioning within the wireless communication network 100, legacy UEs, baseline UEs, high-level UEs, advanced UEs, full-capability UEs, and / or premium UEs. UEs 120 in the third category may have intermediate-level complexity and / or capabilities (e.g., capabilities between first-category UEs 120 and second-capability UEs 120). UEs 120 in the third category may be referred to as reduced-capability UEs (“RedCap UEs”), intermediate-level UEs, NR lightweight UEs, and / or NR-Lite UEs, etc. RedCap UEs bridge the gap in capabilities and complexity between NB-IoT devices and / or eMTC UEs and mission-critical IoT devices and / or premium UEs. RedCap UEs can include, for example, wearable devices, IoT devices, industrial sensors, and / or cameras associated with limited bandwidth, power capacity, and / or transmission range. RedCap UEs can support healthcare environments, building automation, power distribution, process automation, transportation and logistics, and / or smart city deployments, among others.

[0061] In some examples, two or more UEs 120 (e.g., shown as UE 120a and UE 120e) can communicate directly with each other using sidelink communication (e.g., without communication through a network node 110 acting as an intermediary). As an example, UE 120a can directly send data, control information, or other signaling to UE 120e as sidelink communication. This contrasts with, for example, UE 120a first sending data to network node 110 in UL communication, and then that network node sending data to UE 120e in DL communication. In various examples, UE 120 can use peer-to-peer (P2P) communication protocols, device-to-device (D2D) communication protocols, vehicle-to-everything (V2X) communication protocols (which may include vehicle-to-vehicle (V2V) protocols, vehicle-to-infrastructure (V2I) protocols, and / or vehicle-to-pedestrian (V2P) protocols), and / or mesh network communication protocols to send and receive sidelink communication. In some deployments and configurations, network node 110 may schedule and / or allocate resources for sidelink communication between UEs 120 in the wireless communication network 100. In some other deployments and configurations, UE 120 (instead of network node 110) may perform or cooperate with or negotiate with one or more other UEs to perform scheduling operations, resource selection operations, and / or other operations for sidelink communication.

[0062] In various examples, in addition to half-duplex operation, some network nodes and UEs in the wireless communication network 100, including network node 110 and UE 120, can also be configured for full-duplex operation. Network node 110 or UE 120 operating in half-duplex mode can perform only one of transmission or reception during a specific time resource period (such as a specific time slot, symbol, or other time period). Half-duplex operation may involve time division duplex (TDD), where the DL transmission of network node 110 and the UL transmission of UE 120 do not occur in the same time resource (i.e., the transmissions do not overlap in time). In contrast, network node 110 or UE 120 operating in full-duplex mode can transmit and receive communications concurrently (e.g., within the same time resource). By operating in full-duplex mode, network node 110 and / or UE 120 can generally increase the capacity of the network and radio access links. In some examples, full-duplex operation may involve frequency division duplex (FDD), in which network node 110 performs DL transmission in a first frequency band or on a first component carrier, and UE 120 performs transmission in a second frequency band or on a second component carrier, the second frequency band or the second component carrier being different from the first frequency band or the first component carrier, respectively. In some examples, full-duplex operation may be enabled for UE 120 but not for network node 110. For example, UE 120 may simultaneously transmit UL to the first network node 110 and receive DL transmissions from the second network node 110 in the same time resources. In some other examples, full-duplex operation may be enabled for network node 110 but not for UE 120. For example, network node 110 may simultaneously transmit DL to the first UE 120 and receive UL transmissions from the second UE 120 in the same time resources. In some other examples, full-duplex operation may be enabled for both network node 110 and UE 120.

[0063] In some examples, UE 120 and network node 110 can perform MIMO communication. "MIMO" generally refers to the simultaneous transmission or reception of multiple signals (such as multiple layers or multiple data streams) using the same time and frequency resources. MIMO techniques typically utilize multipath propagation. MIMO can be implemented using various spatial processing or spatial multiplexing operations. In some examples, MIMO can support simultaneous transmission to multiple receivers, which is called multi-user MIMO (MU-MIMO). Some RATs can employ advanced MIMO techniques such as mTRP operations (including redundant transmission or reception on multiple TRPs), reciprocity in the time or frequency domain, single-frequency network (SFN) transmission, or noncoherent joint transmission (NC-JT).

[0064] In some aspects, UE 120 may include a communication manager 140. As described in more detail elsewhere herein, the communication manager 140 may send at least one of the following to at least one of a first network node associated with a first cell group or a second network node associated with a second cell group: first information associated with splitting data volume across the first and second cell groups, or second information associated with sharing UE resources across the first and second cell groups; and to communicate via the first and second cell groups based on at least one of the following: splitting data volume across the first and second cell groups based at least in part on the first information, or allocating UE resources across the first and second cell groups based at least in part on the second information. Additionally or alternatively, the communication manager 140 may perform one or more other operations described herein.

[0065] In some aspects, network node 110 may include communication manager 150. As described in more detail elsewhere herein, communication manager 150 may receive from the UE at least one of the following: first information associated with splitting data volume across a first cell group associated with network node 110 and a second cell group associated with another network node, or second information associated with sharing UE resources across the first cell group and the second cell group; and communicate with the UE based on at least one of the following: splitting data volume across the first cell group and the second cell group at least in part based on the first information, or allocating UE resources across the first cell group and the second cell group at least in part based on the second information.

[0066] Additionally or alternatively, as described in more detail elsewhere herein, the communication manager 150 may receive first channel state information (CSI) associated with the UE and a first cell group from the UE; obtain second CSI associated with the UE and a second cell group from another network node; and send to the UE an indication of the splitting of the amount of data to be used for communication with the UE across the first and second cell groups, wherein the splitting of the amount of data across the first and second cell groups is based at least in part on the first and second CSIs. Additionally or alternatively, the communication manager 150 may perform one or more other operations described herein.

[0067] As indicated above, Figure 1 This is provided as an example. Other examples are available with reference to [the relevant information]. Figure 1 The examples described are different.

[0068] Figure 2 This is a diagram illustrating communication between an example network node 110 and an example UE 120 in a wireless network according to the present disclosure.

[0069] like Figure 2As shown, network node 110 may include a data source 212, a transmit processor 214, a transmit (TX) MIMO processor 216, a set of modems 232 (shown as 232a to 232t, where t≥1), a set of antennas 234 (shown as 234a to 234v, where v≥1), a MIMO detector 236, a receive processor 238, a data sink 239, a controller / processor 240, a memory 242, a communication unit 244, a scheduler 246, and / or a communication manager 150, etc. In some configurations, one or a combination of antennas 234, modems 232, MIMO detectors 236, receive processors 238, transmit processors 214, and / or TX MIMO processors 216 may be included in the transceiver of network node 110. The transceiver may be under the control of and used by one or more processors (such as controller / processor 240), and in some respects, may perform aspects of the methods, procedures and / or operations described herein in conjunction with processor-readable code stored in memory 242. In some respects, network node 110 may include one or more interfaces, communication components and / or other components that facilitate communication with UE 120 or another network node.

[0070] The terms “processor,” “controller,” or “controller / processor” can refer to one or more controllers and / or one or more processors. For example, references to “processor,” “controller / processor,” etc. (in the singular) should be understood as referring to a combination of… Figure 2 The processor described refers to any one or more processors, such as a single processor or a combination of multiple different processors. The reference to "one or more processors" should be understood as a combination of references. Figure 2 Any one or more processors described herein. For example, one or more processors of network node 110 may include transmit processor 214, TX MIMO processor 216, MIMO detector 236, receive processor 238, and / or controller / processor 240. Similarly, one or more processors of UE 120 may include MIMO detector 256, receive processor 258, transmit processor 264, TX MIMO processor 266, and / or controller / processor 280.

[0071] In some aspects, a single processor can perform all operations described as being performed by one or more processors. In some aspects, a first set of one or more processors can perform a first operation described as being performed by that one or more processors, and a second set of one or more processors can perform a second operation described as being performed by that one or more processors. The processors in the first set and the processors in the second set can be from the same set of processors or can be from different sets of processors. The reference to "one or more memories" should be understood to refer to any one or more memories of the corresponding device, such as those in combination. Figure 2 The memory described. For example, an operation described as being performed by one or more memories can be performed by the same subset of the one or more memories or by different subsets of the one or more memories.

[0072] For downlink communication from network node 110 to UE 120, transmitting processor 214 may receive data (“downlink data”) intended for use by UE 120 (or a set of UEs including UE 120) from data source 212 (such as a data pipeline or data queue). In some examples, transmitting processor 214 may select one or more MCSs for UE 120 based on one or more Channel Quality Indicators (CQIs) received from UE 120. Network node 110 may process the data (e.g., including encoding the data) based on the MCS selected for UE 120 for transmission to UE 120 on the downlink, thereby generating data symbols. Transmitting processor 214 may process system information (e.g., semi-static resource partitioning information (SRPI)) and / or control information (e.g., CQI requests, grants, and / or upper-layer signaling) and provide overhead symbols and / or control symbols. The transmitting processor 214 can generate reference symbols for reference signals (e.g., cell-specific reference signals (CRS), demodulation reference signals (DMRS), or CSI reference signals (CSI-RS)) and / or synchronization signals (e.g., primary synchronization signal (PSS) or secondary synchronization signal (SSS)).

[0073] The TX MIMO processor 216 can perform space processing (e.g., pre-decoding) on ​​data symbols, control symbols, overhead symbols, and / or reference symbols where applicable, and can output a set of symbol streams (e.g., TA set of output symbol streams is provided to modem 232. For example, each output symbol stream may be provided to a corresponding modulator component (shown as MOD) of modem 232. Each modem 232 may use the corresponding modulator component to process (e.g., modulate) the corresponding output symbol stream (e.g., for orthogonal frequency division multiplexing (OFDM)) to obtain an output sample stream. Each modem 232 may further use the corresponding modulator component to process (e.g., convert to analog, amplify, filter, and / or upconvert) the output sample stream to obtain a time-domain downlink signal. Modems 232a to 232t may transmit the downlink signal set (e.g., ...) together via the corresponding set of antennas 234. T (One downlink signal).

[0074] Downlink signals may include DCI communication, MAC control element (MAC-CE) communication, RRC communication, downlink reference signals, or another type of downlink communication. Downlink signals may be transmitted on the PDCCH, PDSCH, and / or on another downlink channel. Downlink signals may carry one or more transport blocks (TBs) of data. A TB may be a data unit transmitted via the air interface in the wireless communication network 100. A data stream (e.g., from data source 212) may be encoded into multiple TBs for transmission via the air interface. The number of TBs used to carry data associated with a particular data stream may be associated with a TB size shared by multiple TBs. The TB size may be based on the radio channel conditions of the air interface, the MCS used to encode the data, downlink resources allocated for transmitting data, and / or other parameters, or otherwise associated with them. Generally, a larger TB size allows for a larger amount of data to be transmitted in a single transmission, reducing signaling overhead. However, a larger TB size may be more prone to transmission and / or reception errors than a smaller TB size, but such errors can be mitigated through more robust error correction techniques.

[0075] For uplink communication from UE 120 to network node 110, the uplink signal from UE 120 may be received by antenna 234, processed by modem 232 (e.g., demodulator component of modem 232, shown as DEMOD), detected by MIMO detector 236 (e.g., receive (Rx) MIMO processor) where applicable, and / or further processed by receive processor 238 to obtain decoded data and / or control information. Receive processor 238 may provide the decoded data to data sink 239 (which may be a data pipeline, data queue, and / or another type of data sink) and provide the decoded control information to processors such as controller / processor 240.

[0076] Network node 110 may use scheduler 246 to schedule one or more UEs 120 for downlink or uplink communication. In some aspects, scheduler 246 may use DCI to dynamically schedule DL transmissions to and / or UL transmissions from UE 120. In some examples, scheduler 246 may allocate repetitive time-domain and / or frequency-domain resources that UE 120 may use to transmit and / or receive communication using RRC configuration (e.g., semi-static configuration), for example, to perform semi-persistent scheduling (SPS) or to configure configuration grant (CG) for UE 120.

[0077] One or more of the following may be included in the RF chain of network node 110: transmit processor 214, TX MIMO processor 216, modem 232, antenna 234, MIMO detector 236, receive processor 238, and / or controller / processor 240. The RF chain may include one or more filters, mixers, oscillators, amplifiers, analog-to-digital converters (ADCs), and / or other devices for converting between analog signals (such as those used for transmission or reception via an air interface) and digital signals (such as those used for processing by one or more processors of network node 110). In some aspects, the RF chain may be a transceiver of network node 110, or may be included in such a transceiver.

[0078] In some examples, network node 110 may use communication unit 244 to communicate with the core network and / or other network nodes. Communication unit 244 may support wired and / or wireless communication protocols and / or connections, such as Ethernet, fiber optic, Common Public Radio Interface (CPRI), and / or wired or wireless backhaul, etc. Network node 110 may use communication unit 244 to send and / or receive data associated with UE 120, or to perform network control signaling, etc. Communication unit 244 may include transceivers and / or interfaces, such as network interfaces.

[0079] UE 120 may include a collection of antennas 252 (shown as antennas 252a to 252r, where r ≥ 1), a collection of modems 254 (shown as modems 254a to 254u, where u ≥ 1), a MIMO detector 256, a receive processor 258, a data sink 260, a data source 262, a transmit processor 264, a TX MIMO processor 266, a controller / processor 280, a memory 282, and / or a communication manager 140, etc. One or more components of UE 120 may be included in housing 284. In some aspects, one or a combination of antenna 252, modem 254, MIMO detector 256, receive processor 258, transmit processor 264, or TX MIMO processor 266 may be included in a transceiver included in UE 120. The transceiver may be under the control of and used by one or more processors (such as controller / processor 280), and in some respects, may perform aspects of the methods, procedures, or operations described herein in conjunction with processor-readable code stored in memory 282. In some respects, UE 120 may include another interface, another communication component, and / or another component that facilitates communication with network node 110 and / or another UE 120.

[0080] For downlink communication from network node 110 to UE 120, the set of antennas 252 can receive downlink communication or signals from network node 110, and can receive the set of downlink signals (e.g., R Each received signal is provided to a set of modems 254. For example, each received signal may be provided to a corresponding demodulator component (shown as DEMOD) of 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 an input sample. Each modem 254 may use the corresponding demodulator component to further demodulate or process the input sample (e.g., for OFDM) to obtain a received symbol. MIMO detector 256 may obtain the received symbols from the set of modems 254, perform MIMO detection on the received symbols where applicable, and provide the detected symbols. Receiver processor 258 may process (e.g., decode) the detected symbols, provide the decoded data for UE 120 to data sink 260 (which may include data pipelines, data queues, and / or applications executed on UE 120), and provide the decoded control information and system information to controller / processor 280.

[0081] For uplink communication from UE 120 to network node 110, the transmitting processor 264 may receive and process data (“uplink data”) from data source 262 (such as data pipelines, data queues, and / or applications running on UE 120) and control information from controller / processor 280. The control information may include one or more parameters, feedback, one or more signal measurements, and / or other types of control information. In some aspects, the receiving processor 258 and / or controller / processor 280 may determine one or more parameters related to the transmission of uplink communication for received signals (such as those received from network node 110 or another UE). One or more parameters may include RSRP parameters, Received Signal Strength Indicator (RSSI) parameters, Reference Signal Receive Quality (RSRQ) parameters, CQI parameters, or Transmit Power Control (TPC) parameters, etc. The control information may include indications of RSRP parameters, RSSI parameters, RSRQ parameters, CQI parameters, TPC parameters, and / or other parameters. The control information may facilitate parameter selection and / or scheduling for UE 120 by network node 110.

[0082] Transmit processor 264 can generate reference symbols for one or more reference signals, such as uplink DMRS, uplink sounding reference signal (SRS), and / or another type of reference signal. Symbols from transmit processor 264 can be pre-decoded by TX MIMO processor 266 where applicable, and further processed by a set of modems 254 (e.g., for DFT-s-OFDM or CP-OFDM). TX MIMO processor 266 can perform spatial processing (e.g., pre-decoding) on ​​data symbols, control symbols, overhead symbols, and / or reference symbols where applicable, and can output a set of symbol streams (e.g., ... U A set of output symbol streams is provided to modem 254. For example, each output symbol stream may be provided to a corresponding modulator component (shown as MOD) of modem 254. Each modem 254 may use the corresponding modulator component to process (e.g., modulate) the corresponding output symbol stream (e.g., for OFDM) to obtain an output sample stream. Each modem 254 may further use the corresponding modulator component to process (e.g., convert to analog, amplify, filter, and / or upconvert) the output sample stream to obtain an uplink signal.

[0083] Modems 254a to 254u can transmit uplink signal sets (e.g., via corresponding sets of antennas 252) R One uplink signal or UUplink signals may include UCI communication, MAC-CE communication, RRC communication, or another type of uplink communication. Uplink signals may be transmitted on PUSCH, PUCCH, and / or another type of uplink channel. Uplink signals may carry one or more TBs of data. Sidelink data and control transmission (i.e., transmission directly between two or more UEs 120) may typically use techniques similar to those described for uplink data and control transmission, and may use sidelink-specific channels such as the Physical Sidelink Shared Channel (PSSCH), Physical Sidelink Control Channel (PSCCH), and / or Physical Sidelink Feedback Channel (PSFCH).

[0084] One or more antennas in the set of antennas 252 or the set of antennas 234 may include one or more antenna panels, one or more antenna groups, one or more sets of antenna elements, or one or more antenna arrays, etc., or may be included in one or more antenna panels, one or more antenna groups, one or more sets of antenna elements, or one or more antenna arrays, etc. Antenna panels, antenna groups, sets of antenna elements, or antenna arrays 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, or with one or more transmitting or receiving components (such as...) Figure 2 An antenna module is a combination of one or more antenna elements coupled to one or more components. As used herein, "antenna" can mean one or more antennas, one or more antenna panels, one or more antenna groups, one or more collections of antenna elements, or one or more antenna arrays. "Antenna panel" can mean a group of antennas (such as antenna elements) arranged in an array or panel that can facilitate beamforming by manipulating the parameters of that group of antennas. "Antenna module" can mean a circuit that includes one or more antennas, and may also include one or more other components (such as filters, amplifiers, or processors) associated with integrating the antenna module into a wireless communication device.

[0085] In some examples, each antenna element of antenna 234 or antenna 252 may include one or more sub-elements for radiating or receiving radio frequency signals. For example, a single antenna element may include a first sub-element cross-polarized with a second sub-element that can be used to independently transmit the cross-polarized signal. Antenna elements may include patch antennas, dipole antennas, and / or other types of antennas arranged in a linear pattern, a two-dimensional pattern, or another pattern. The spacing between antenna elements can allow signals with a desired wavelength transmitted individually by the antenna elements to interact or interfere (e.g., to form a desired beam) in various directions. For example, given a desired wavelength or frequency range, the spacing may provide a quarter wavelength, half a wavelength, or another fraction of the wavelength between adjacent antenna elements to allow desired constructive and destructive interference modes of signals transmitted by individual antenna elements within that desired range.

[0086] The amplitude and / or phase of signals transmitted via antenna elements and / or sub-elements can be modulated and (e.g., by manipulating phase shifts, phase offsets, and / or amplitudes) shifted relative to each other to generate one or more beams; this is known as beamforming. The term "beam" can refer to the directional transmission of a wireless signal toward a receiving device or otherwise in a desired direction. "Beam" can also generally refer to the direction associated with such directional signal transmission, the set of directional resources associated with the signal transmission (e.g., angle of arrival, horizontal direction, and / or vertical direction), and / or a set of parameters indicating one or more aspects of the directional signal, the direction associated with the signal, and / or the set of directional resources associated with the signal. In some implementations, antenna elements can be individually selected or deselected for the directional transmission of a signal (or multiple signals) by controlling the amplitude of one or more corresponding amplifiers and / or the phase of the signal to form one or more beams. The shape of the beam (such as amplitude, width, and / or the presence of sidelobes) and / or the direction of the beam (such as the angle of the beam relative to the surface of the antenna array) can be dynamically controlled by modifying the phase shifts, phase offsets, and / or amplitudes of multiple signals relative to each other.

[0087] Different UEs 120 or network nodes 110 may include different numbers of antenna elements. For example, UE 120 may include a single antenna element, two antenna elements, four antenna elements, eight antenna elements, or different numbers of antenna elements. As another example, network node 110 may include eight antenna elements, 24 antenna elements, 64 antenna elements, 128 antenna elements, or different numbers of antenna elements. Generally speaking, a larger number of antenna elements provides increased control over the parameters used for beamforming compared to a smaller number of antenna elements, while a smaller number of antenna elements may be less complex to implement and can use less power. Multiple antenna elements can support multi-layer transmission, in which the same time and frequency resources are used to utilize spatial multiplexing to transmit a first layer of communication (which may include a first data stream) and a second layer of communication (which may include a second data stream).

[0088] Although Figure 2 The boxes in the diagram are illustrated as different components, but the functions described above with respect to these boxes may be implemented in a single hardware, software, or combined component, or in various combinations of components. For example, the functions described with respect to transmit processor 264, receive processor 258, and / or TX MIMO processor 266 may be performed by or under the control of controller / processor 280.

[0089] Figure 3 This is an illustration of an example disaggregated base station architecture 300 according to the present disclosure. One or more components of the example disaggregated base station architecture 300 may be one or more network nodes (such as one or more network nodes 110), may include, or may be included in one or more network nodes. The disaggregated base station architecture 300 may include a CU 310, which may communicate directly with the core network 320 via a backhaul link, or may communicate indirectly with the core network 320 via one or more disaggregated control units (such as non-RT RIC 350 and / or near-RT RIC 370 associated with a Service Management and Orchestration (SMO) framework 360 (e.g., via an E2 link)). The CU 310 may communicate with one or more DU 330 via a corresponding midhaul link (such as via an F1 interface). Each DU 330 may communicate with one or more RU 340 via a corresponding fronthaul link. Each RU 340 may communicate with one or more UE 120 via a corresponding RF access link. In some deployments, UE 120 can be served by multiple RU 340s simultaneously.

[0090] Each component of the disassembled base station architecture 300 (including CU 310, DU 330, RU 340, near-RT RIC 370, non-RT RIC 350, and SMO frame 360) may include one or more interfaces or may be coupled to one or more interfaces for receiving or transmitting signals, such as data or information, via wired or wireless transmission media.

[0091] In some respects, the CU 310 can be logically divided into one or more CU user plane (CU-UP) units and one or more CU control plane (CU-CP) units. When implemented in an O-RAN configuration, the CU-UP units can communicate bidirectionally with the CU-CP units via an interface such as an E1 interface. The CU 310 can be deployed to communicate with one or more DU 330s for network control and signaling, as needed. 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 RU 340s. For example, the DU 330 may host various layers, such as the RLC layer, MAC layer, or one or more PHY layers (such as one or more high PHY layers or one or more low PHY layers). Each layer (which may also be referred to as a module) can be implemented using an interface for signaling to other layers (and modules) hosted by the DU 330, or for signaling to control functions hosted by the CU 310. Each RU 340 may implement lower-layer functionality. In some respects, the real-time and non-real-time aspects of communication with the control plane and user plane of the RU 340 can be controlled by the corresponding DU 330.

[0092] The SMO framework 360 supports RAN deployment and provisioning for both non-virtualized and virtualized network elements. For non-virtualized network elements, the SMO framework 360 supports the deployment of dedicated physical resources for RAN coverage requirements, which can be managed via operation and maintenance interfaces such as the O1 interface. For virtualized network elements, the SMO framework 360 can interact with cloud computing platforms such as the Open Cloud (O-Cloud) platform 390 to perform network element lifecycle management (such as instantiating virtualized network elements) via cloud computing platform interfaces such as the O2 interface. Virtualized network elements may include, but are not limited to, CU 310, DU 330, RU 340, non-RT RIC 350, and / or near-RT RIC 370. In some aspects, the SMO framework 360 can communicate with hardware aspects of the 4G RAN, 5G NR RAN, and / or 6G RAN (such as the Open eNB (O-eNB) 380) via the O1 interface. Additionally or alternatively, the SMO framework 360 can communicate directly with each of one or more RUs 340 via the corresponding O1 interface. In some deployments, this configuration enables each DU 330 and CU 310 to be implemented in a cloud-based RAN architecture, such as a vRAN architecture.

[0093] The non-RT RIC 350 may include or implement logic functions that enable non-real-time control and optimization of RAN elements and resources, including AI / ML workflows for model training and updates, and / or policy-based guidance of applications and / or features in the near-RT RIC 370. The non-RT RIC 350 may be coupled to or communicate with the near-RT RIC 370, such as via an A1 interface. The near-RT RIC 370 may include or implement logic functions that enable near real-time control and optimization of RAN elements and resources via an interface, such as an E2 interface, through data collection and action, connecting one or more CU 310s, one or more DU 330s, and / or O-eNBs to the near-RT RIC 370.

[0094] In some aspects, to generate AI / ML models to be deployed in the near-RT RIC 370, the non-RT RIC 350 may receive parameters or external enrichment information from an external server. This information can be utilized by the near-RT RIC 370 and can be received from non-network data sources or network functions at the SMO framework 360 or the non-RT RIC 350. In some examples, the non-RT RIC 350 or near-RT RIC 370 may modulate RAN behavior or performance. For example, the non-RT RIC 350 may monitor long-term trends and patterns in performance and may perform corrective actions using AI / ML models via the SMO framework 360 (such as reconfiguration via the O1 interface) or via the creation of RAN management policies (such as A1 interface policies).

[0096] Figure 1 , Figure 2 or Figure 3 Network node 110, its controller / processor 240, UE 120, UE 120's controller / processor 280, CU 310, DU 330, RU 340, or any other component may implement one or more technologies or perform one or more operations associated with UE information for enhanced multicarrier communication, as described in more detail elsewhere herein. For example, network node 110's controller / processor 240, UE 120's controller / processor 280, CU 310, DU 330, RU 340, or any other component may implement one or more technologies or perform one or more operations associated with UE information for enhanced multicarrier communication, as described in more detail elsewhere herein. Figure 2 Any other component, CU 310, DU 330, or RU 340 may (alone or in combination with one or more other processors) perform or direct, for example... Figure 12 Process 1200 Figure 13 Process 1300 Figure 14The operation of process 1400 or other processes as described herein. Memory 242 may store data and program code for network node 110, CU 310, DU 330, or RU 340. Memory 282 may store data and program code for UE 120. In some examples, memory 242 or memory 282 may include a non-transitory computer-readable medium storing a set of instructions (e.g., code or program code) for wireless communication. Memory 242 may include one or more memories, such as a single memory or multiple different memories (of the same or different types). Memory 282 may include one or more memories, such as a single memory or multiple different memories (of the same or different types). For example, the set of instructions may be executed by one or more processors of network node 110, UE 120, CU 310, DU 330, or RU 340 (e.g., directly, or after compilation, transformation, or interpretation). Figure 12 Process 1200 Figure 13 Process 1300 Figure 14 The process 1400 or other processes as described herein. In some examples, the execution instructions may include run instructions, transform instructions, compile instructions, and / or interpret instructions, etc.

[0097] In some aspects, the UE (e.g., UE 120) includes: components for transmitting at least one of the following to at least one of a first network node associated with a first cell group or a second network node associated with a second cell group: first information associated with splitting data volume across the first and second cell groups, or second information associated with sharing UE resources across the first and second cell groups; and / or components for communicating via the first and second cell groups according to at least one of the following: splitting data volume across the first and second cell groups based at least in part on the first information, or allocating UE resources across the first and second cell groups based at least in part on the second information. Components for the UE to perform the operations described herein may include, for example, one or more of the following: a communication manager 140, an antenna 252, a modem 254, a MIMO detector 256, a receive processor 258, a transmit processor 264, a TX MIMO processor 266, a controller / processor 280, or a memory 282.

[0098] In some aspects, a network node (e.g., network node 110) includes: components for receiving from a UE at least one of: first information associated with splitting data amounts across a first cell group associated with the network node and a second cell group associated with another network node, or second information associated with sharing UE resources across the first cell group and the second cell group; and / or components for communicating with the UE based on at least one of: splitting data amounts across the first cell group and the second cell group at least in part based on the first information, or allocating UE resources across the first cell group and the second cell group at least in part based on the second information.

[0099] In some aspects, a network node (e.g., network node 110) includes: components for receiving a first CSI associated with the UE and a first cell group from the UE; components for obtaining a second CSI associated with the UE and a second cell group from another network node; and / or components for sending to the UE an indication of the splitting of the amount of data to be used for communication with the UE across the first and second cell groups, wherein the splitting of the amount of data across the first and second cell groups is at least partially based on the first and second CSIs. Components for the network node to perform the operations described herein may include, for example, one or more of the following: a communication manager 150, a transmit processor 214, a TX MIMO processor 216, a modem 232, an antenna 234, a MIMO detector 236, a receive processor 238, a controller / processor 240, a memory 242, or a scheduler 246.

[0100] As indicated above, Figure 3 This is provided as an example. Other examples are available with reference to [the relevant information]. Figure 3 The examples described are different.

[0101] Figure 4 This is a diagram illustrating Example 400 of the CA according to this disclosure.

[0102] Carrier aggregation (CA) is a technique that enables two or more carriers (sometimes referred to as "carriers") to be combined (e.g., combined into a single channel) to enhance the data capacity of a single UE 120. As shown in the figure, carriers (shown as the first carrier (CC 1) 402 and the second carrier (CC 2) 404) can be combined in the same or different frequency bands (shown as the first frequency band (band 1) 406 and the second frequency band (band 2) 408). Additionally or alternatively, contiguous or discontinuous carriers can be combined. Network node 110 can configure carrier aggregation for UE 120, such as in RRC messages, DCI and / or other signaling messages.

[0103] As shown by reference numeral 405, in some aspects, carrier aggregation can be configured in an intra-band continuous mode, wherein the aggregated carriers (e.g., CC 1 402 and CC 2 404) are continuous with each other and in the same frequency band (e.g., band 1 406). As shown by reference numeral 410, in some aspects, carrier aggregation can be configured in an intra-band discontinuous mode, wherein the aggregated carriers (e.g., CC 1 402 and CC 2 404) are discontinuous with each other and in the same frequency band (e.g., band 1 406). As shown by reference numeral 415, in some aspects, carrier aggregation can be configured in an inter-band discontinuous mode, wherein the aggregated carriers (e.g., CC 1 402 and CC 2 404) are discontinuous with each other and in different frequency bands (e.g., band 1 406 and band 2 408).

[0104] In carrier aggregation, UE 120 can be configured using a primary carrier or primary cell (PCell) and one or more secondary carriers or secondary cells (SCells). In some aspects, the primary carrier may carry control information (e.g., downlink control information and / or scheduling information) for scheduling data communications on one or more secondary carriers; this may be referred to as cross-carrier scheduling. In some aspects, a carrier (e.g., a primary carrier or a secondary carrier) may carry control information for scheduling data communications on that carrier; this may be referred to as self-carrier scheduling or carrier self-scheduling.

[0105] As indicated above, Figure 4 This is provided as an example. Other examples are available with reference to [the relevant information]. Figure 4 The examples described are different.

[0106] Figure 5 This is an illustration of example 500 of a DC according to various aspects of this disclosure.

[0107] like Figure 5 As shown, in NR, DC is a feature where UE 120 can communicate with two network nodes to increase bandwidth and reduce service latency. One network node acts as MN 502 and the other acts as SN 504. MN 502 can be an eNB (e.g., a 4G network node, an LTE network node, etc.), a gNB DU (e.g., a 5G network node, an NR network node, etc.), or a 6G network node, etc. SN 504 can be a gNB DU (e.g., a 5G network node, an NR network node, etc.) or a 6G network node, etc. MN 502 and SN 504 can communicate with the 4G / LTE core network, the 5G / NR core network (e.g., via a gNB CU), and / or the 6G core network, etc. (e.g., directly or indirectly).

[0108] In some cases, DC can be used in conjunction with CA. When using CA, there may be multiple serving cells (e.g., one serving cell per carrier). The coverage of the serving cells may differ, for example, due to different carriers on different frequency bands experiencing different path losses.

[0109] In the DC, MN 502 can communicate with UE 120 via the MCG. When CA is activated, the MCG can include multiple serving cells (e.g., Pcells and one or more Scells). When CA is not activated, the MCG can include a single serving cell. SN 504 can communicate with UE 120 via the SCG. When CA is activated, the SCG can include multiple serving cells (e.g., primary and secondary cells (PScells) and one or more Scells). When CA is not activated, the SCG can include a single serving cell.

[0110] As indicated above, Figure 5 This is provided as an example. Other examples are available with reference to [the relevant information]. Figure 5 The examples described are different.

[0111] Figure 6 This is a diagram illustrating example 600 associated with enhanced resource management for DC. For example... Figure 6 As shown, UE 120 can communicate with first network node 110-1 and second network node 110-2. In some aspects, first network node 110-1, second network node 110-2, and UE 120 can be part of a wireless network (e.g., wireless network 100). Figure 6 Prior to the operations shown, UE 120 may have established radio connections with the first network node 110-1 and the second network node 110-2. In some aspects, for dual-connectivity communication with UE 120, the first network node 110-1 is the MN and the second network node 110-2 is the SN. In some aspects, for dual-connectivity communication with UE 120, the second network node 110-2 is the MN and the first network node 110-1 is the SN. In some aspects, the first network node 110-1 and the second network node 110-2 may be non-co-located.

[0112] As shown by reference numeral 605, UE 120 can send UE capability information and the first network node 110-1 can receive the UE capability information. For example, the UE can send a capability report including UE capability information and the first network node 110-1 can receive the capability report. Additionally or alternatively, as shown by reference numeral 605a, the second network node 110-2 can receive the UE capability information. In some examples, the second network node 110-2 can receive the UE capability information from the first network node 110-1 (e.g., the first network node 110-1 can forward the UE capability information to the second network node 110-2). In some other examples, the second network node 110-2 can receive the UE capability information from the UE 120 (e.g., as a supplement or alternative to the first network node 110-1 receiving the UE capability information).

[0113] UE capability information may indicate one or more capabilities associated with a DC. For example, UE capability information may indicate whether UE120 supports (e.g., is capable of) DC communication. In some aspects, UE capability information may indicate one or more frequency band combinations for a DC supported by UE 120. In some aspects, UE capability information may indicate UE 120's capabilities for feature sets and / or maximum power in FR1 and FR2.

[0114] like Figure 6 As further illustrated by reference numeral 610, in some aspects, the first network node 110-1 and the second network node 110-2 may coordinate to determine the SCG configuration for UE 120. In some aspects, the MN (e.g., the first network node 110-1) and the SN (e.g., the second network node 110-2) may coordinate to determine the SCG configuration for UE 120 based at least in part on UE capability information. For example, the MN may supervise the resolution of dependencies between the MCG configuration and the SCG configuration of UE 120. The MN may determine the MCG configuration and a list of possible SCG configurations, and the MN may send the list of possible SCG configurations to the SN. The list of possible SCG configurations may include possible DC band combinations and / or feature sets based at least in part on UE capability information. In some examples, the SN may select an SCG configuration from the list of possible SCG configurations and report the selected SCG configuration to the MN. Alternatively, the SN may negotiate with the MN regarding the selection of the SCG configuration. For example, the SN can initiate modifications to the list of possible SCG configurations and indicate one or more desired SCG configurations (e.g., desired frequency band combinations and / or feature sets) outside the list of possible SCG configurations selected by the MN. The MN can then make the final determination of the SCG configuration.

[0115] like Figure 6As further illustrated by reference numeral 615, the first network node 110-1 can send and the UE 120 can receive configuration information. In some examples, the MN (e.g., the first network node 110-1) can send configuration information to the UE 120. In some examples, the UE 120 can receive configuration information from the SN or from both the MN and the SN. In some aspects, the UE 120 can receive configuration information via one or more RRC messages. Additionally or alternatively, the UE 120 can receive configuration information via system information (e.g., Master Information Block (MIB) and / or System Information Block (SIB), one or more MAC-CEs, and / or DCIs, etc.

[0116] In some aspects, the configuration information may indicate one or more candidate configuration and / or communication parameters. In some aspects, these one or more candidate configuration and / or communication parameters may be selected, activated, and / or deactivated by subsequent indications. For example, subsequent indications may select candidate configuration and / or communication parameters from the one or more candidate configuration and / or communication parameters. In some aspects, subsequent indications may include dynamic indications, such as one or more MAC-CE and / or one or more DCI messages, etc.

[0117] In some aspects, the configuration information can configure UE 120 for DC communication. For example, the configuration information may include MCG and SCG configurations for UE 120. In some examples, the configuration information may indicate the CC (or cell) in each cell group, the active BWP for the CC in each cell group, and / or the number of MIMO layers to be used for each cell group, etc. In some examples, the configuration information may configure how UE resources are allocated across MCG and SCG. For example, UE resources may include BB resources, RF resources (e.g., RF chains), and / or antennas for UE 120.

[0118] In some aspects, configuration information may configure UE 120 to perform channel measurements and report channel measurements. For example, configuration information may include configurations for one or more CSI-RS to be measured by UE 120 and configurations for one or more CSI reports to be sent by UE 120. In some aspects, configuration information may configure UE 120 to measure one or more first CSI-RS associated with a first cell group (e.g., MCG) and to measure one or more second CSI-RS associated with a second cell group (e.g., SCG). In such examples, configuration information may configure UE 120 to report the first CSI associated with the first cell group (e.g., MCG) to a first network node 110-1 (e.g., MN) and to report the second CSI associated with the second cell group (e.g., SCG) to a second network node 110-2 (e.g., SN).

[0119] like Figure 6 As further illustrated by reference numeral 620, UE 120 can perform channel measurements on the MCG and SCG. For example, a first network node 110-1 can transmit one or more first CSI-RSs via a first cell group (e.g., MCG), and UE 120 can perform channel measurements on one or more first CSI-RSs. UE 120 can determine or derive a first CSI based at least in part on the channel measurements performed on one or more first CSI-RSs. The first CSI may include one or more estimates and / or measurements of channel conditions (e.g., downlink channel conditions) on UE channels to the first cell group (e.g., MCG). UE 120 can perform channel measurements for each CC of the first cell group, and the first CSI may include a CSI for each CC of the first cell group. A second network node can transmit one or more second CSI-RSs via a second cell group (e.g., SCG), and UE 120 can perform channel measurements on one or more second CSI-RSs. UE 120 can determine or derive a second CSI based at least in part on the channel measurements performed on one or more second CSI-RSs. The second CSI may include one or more estimates and / or measurements of channel conditions (e.g., downlink channel conditions) on UE channels to the second cell group (e.g., SCG). UE120 may perform channel measurements for each CC of the second cell group, and the second CSI may include CSI for each CC of the second cell group.

[0120] like Figure 6 As further illustrated by reference numeral 625, UE 120 can send, and first network node 110-1 can receive, a first CSI. For example, UE 120 can send a first CSI report including the first CSI to first network node 110-1. The first CSI is associated with UE 120 and a first cell group (e.g., MCG). That is, the first CSI indicates to first network node 110-1 the channel condition of the downlink channel (e.g., the UE channel to the first cell group) between first network node 110-1 and UE 120. In some other examples, where downlink / uplink reciprocity is maintained between UE 120 and first network node 110-1, first network node 110-1 can determine the channel condition of the downlink channel between first network node 110-1 and UE 120 via uplink channel probing.

[0121] like Figure 6As further illustrated by reference numeral 630, UE 120 can send, and second network node 110-2 can receive, a second CSI. For example, UE 120 can send a second CSI report including the second CSI to second network node 110-2. The second CSI is associated with UE 120 and a second cell group (e.g., SCG). That is, the second CSI indicates to second network node 110-2 the channel condition of the downlink channel (e.g., the UE channel to the second cell group) between second network node 110-2 and UE 120. In some other examples, where downlink / uplink reciprocity is maintained between UE 120 and second network node 110-2, second network node 110-2 can determine the channel condition of the downlink channel between second network node 110-2 and UE 120 via uplink channel probing.

[0122] like Figure 6 As further shown by reference numeral 635, the first network node 110-1 and / or the second network node 110-2 may communicate the CSI received from the UE 120, and the first network node 110-1 and / or the second network node 110-2 may determine the split ratio (or split factor) for splitting network resources across the first cell group (e.g., MCG) and the second cell group (e.g., SCG).

[0123] In some respects, the MN and SN can exchange their local CSIs (e.g., the CSI associated with the MCG and the CSI associated with the SCG). For example, the first network node 110-1 can send a first CSI to the second network node 110-2 and receive (e.g., receive) a second CSI from the second network node 110-2, and the second network node 110-2 can send a second CSI to the first network node 110-1 and receive (e.g., receive) a first CSI from the first network node 110-1. In some other respects, one of the MN or SN can send a local CSI received from the UE 120 to the other of the MN or SN. In some examples, the first network node 110-1 can receive a second CSI from the second network node 110-2 (e.g., the second network node 110-2 can send a second CSI to the first network node 110-1). In some other examples, the second network node 110-2 may obtain the first CSI from the first network node 110-1 (e.g., the first network node 110-1 may send the first CSI to the second network node 110-2). In some aspects, the CSI sent by the MN (e.g., the first network node 110-1) and / or the SN (e.g., the second network node 110-2) may include information identifying UE 120 and each serving cell of UE 120 (e.g., information that associates the CSI with UE 120 and each serving cell of UE 120) or be sent with that information. In some other aspects, UE 120 may be configured to report the CSI of one cell group (or portions of the CSI, such as CQI, Pre-decoded Matrix Indicator (PMI), or Layer 1 RSRP (L1-RSRP)) to another cell group. For example, UE 120 may send a second CSI to both the second cell group (e.g., SCG) and the first cell group (e.g., MCG). In such examples, it may not be necessary for the first network node 110-1 (e.g., MN) and the second network node 110-2 (e.g., SN) to exchange CSI.

[0124] The first network node 110-1 and / or the second network node 110-2 may determine the split ratio (or split factor) at least in part based on the first CSI and the second CSI. The split ratio is the ratio used to split data / traffic across a first cell group (e.g., MCG) and a second cell group (e.g., SCG). Therefore, the split ratio indicates the splitting of data across the first and second cell groups. In some examples, the split ratio may be at least in part based on the splitting of network resources across the first and second cell groups determined by the first network node 110-1 and / or the second network node 110-2. The first network node 110-1 and the second network node 110-2 may use the split ratio to split downlink data between the first and second cell groups, and the UE 120 may use the split ratio to split uplink data between the first and second cell groups. In some aspects, the first network node 110-1 and / or the second network node 110-2 may determine the same split ratio for downlink and uplink, or the first network node 110-1 and / or the second network node 110-2 may determine different split ratios for downlink and uplink. In some examples, the first network node 110-1 and / or the second network node 110-2 may determine / select the split ratio based on the first CSI, the second CSI, and the available bandwidth of UE 120 in each cell group. In some examples, the first network node 110-1 and / or the second network node 110-2 may determine / select the split ratio based on the first CSI, the second CSI, the available bandwidth of UE 120 in each cell group, and / or other information such as cell load information. In some examples, the first network node 110-1 and / or the second network node 110-2 may determine the split ratio to favor the use of cell groups with better channel conditions (e.g., MCG or SCG), so that the UE 120 will use cell groups with better channel conditions to send and / or receive more data.

[0125] In some aspects, either the MN or the SN can determine or select the split ratio. In some examples, the first network node 110-1 can determine the split ratio. In such examples, the first network node 110-1 can obtain a second CSI from the second network node 110-2, and the first network node 110-1 can determine the split ratio based at least on the first CSI (received from UE 120) and the second CSI. In this case, the first network node 110-1 can report the determined split ratio to the second network node 110-2. In some other examples, the second network node 110-2 can determine the split ratio. In such examples, the second network node 110-2 can obtain a first CSI from the first network node 110-1, and the second network node 110-2 can determine the split ratio based at least on the first CSI and the second CSI (received from UE 120). In this case, the second network node 110-2 can report the determined split ratio to the first network node 110-1. In some aspects, the MN and SN can coordinate to determine the split ratio. For example, the first network node 110-1 and the second network node 110-2 may exchange CSI information and then perform negotiation and / or handshake communication to determine the split ratio based at least in part on the first CSI information and the second CSI information.

[0126] like Figure 6 Furthermore, as indicated by reference numeral 640, the first network node 110-1 can transmit and the UE 120 can receive an indication of the split ratio (or split factor). Additionally or alternatively, as indicated by reference numeral 640a, the second network node 110-2 can transmit and the UE 120 can receive an indication of the split ratio. In some examples, the indication of the split ratio can be transmitted to the UE 120 via the first cell group (e.g., from the first network node 110-1), via the second cell group (e.g., from the second network node 110-2), or via both the first and second cell groups. In some aspects, the indication of the split ratio can be included in the MAC-CE or DCI. For example, the MAC-CE or DCI including the indication of the split ratio can be carried via the MCG (e.g., the first cell group), via the SCG (e.g., the second cell group), or via both the MCG and SCG.

[0127] In some aspects, a split ratio (or split factor) can be indicated to UE 120 as a split threshold. For example, an indication of a split factor can indicate a split threshold. In such examples, UE 120 can apply the split ratio by transmitting a portion of the data volume via one of the first cell group (e.g., MCG) or the second cell group (e.g., SCG) up to reaching the split threshold, and the remaining portion of the data volume via the other of the first cell group (e.g., MCG) or the second cell group (e.g., SCG). In some examples, the split threshold can be represented by the number of bytes (e.g., the number of megabytes). For example, an indication of the split threshold sent to UE 120 via the MCG can be an indication of the amount of data UE 120 transmits via the MCG up to the split threshold (e.g., uplink data) and the remaining amount of data (exceeding the split threshold) via the SCG. The indication of the split threshold sent to UE 120 via SCG can be an indication of the amount of data (e.g., uplink data) that UE 120 sends via SCG up to the split threshold and the amount of remaining data (exceeding the split threshold) sent via MCG.

[0128] like Figure 6 As further illustrated by reference numeral 645, UE 120 can communicate with first network node 110-1 and second network node 110-2 via a first cell group and a second cell group, respectively, according to an indication of the split ratio. In some examples, UE 120 can send uplink communication to first network node 110-1 (e.g., MN) via a first cell group (e.g., MCG) and to second network node 110-2 (e.g., SN) via a second cell group, according to the indication of the split ratio. For example, UE 120 can split uplink data between the first cell group and the second cell group according to the indicated split ratio. When the split ratio is indicated to UE 120 as a split threshold, UE 120 can send the maximum amount of data up to the split threshold via one of the first cell group or the second cell group and send the remaining amount of data (exceeding the split threshold) via the other of the first cell group or the second cell group.

[0129] In some examples, based on the indicated split ratio, a first network node 110-1 may send downlink communication to UE 120 via a first cell group, and a second network node 110-2 may send downlink communication to UE 120 via a second cell group. For example, the first network node 110-1 and the second network node 110-2 may split downlink data between the first cell group and the second cell group according to the split ratio. UE 120 may receive downlink communication split across the first cell group and the second cell group according to the indicated split ratio. When the split ratio is indicated to UE 120 as a split threshold, UE 120 may receive up to the amount of downlink data up to the split threshold via one of the first cell group or the second cell group, and the remaining amount of downlink data (exceeding the split threshold) via the other of the first cell group or the second cell group.

[0130] As referenced above Figure 6 As discussed, the MN and / or SN can exchange the CSI associated with the MCG and the CSI associated with the SCG, and the MN and / or SN can determine the split ratio based at least in part on the CSI associated with the MCG and the CSI associated with the SCG. In some examples, the split ratio can be selected to favor the use of cell groups with better channel conditions (e.g., the MCG or the SCG), allowing more data to be transmitted using the cell groups with better channel conditions. Therefore, when managing network resources for DC communications of UE 120 (e.g., when determining the split ratio), the MN and / or SN may consider the channel conditions (e.g., link quality) of UE 120 on the CCs of the MCG and SCG. This can enhance / increase the downlink and uplink throughput of DC communications. In some examples, the amount of throughput gain may depend on: the information exchange between the MN and SN being fast enough (e.g., including negotiation and / or handshake operations); and the rapid indication to the UE 120 of the split ratio for the uplink (e.g., using MAC-CE or DCI, which can be carried via MCG, SCG, or both MCG and SCG).

[0131] Despite the above reference Figure 6 The operations discussed are described in conjunction with DC, but the above references... Figure 6The operations discussed can be similarly applied to dual-stack (DS) scenarios. In a DS scenario, UE 120 can independently connect to two networks. For example, the two networks may be associated with the same or different operators. UE 120 may have two subscriber identity modules (SIMs) (e.g., two SIM cards), with each SIM used to connect to a different network. In the DS scenario, a first network node 110-1 may be associated with a first network, and a second network node 110-2 may be associated with a second network. UE 120 can connect to the first network via a first link with the first network node 110-1 and to the second network via a second link with the second network node 110-2. In some examples, some applications performing on UE 120 may use the first link, and some applications performing on UE 120 may use the second link. However, there may be little coordination between the two networks. Therefore, applying the above references in a DS scenario is not feasible. Figure 6 In the examples of operations discussed, UE 120 may send the CSI of one network to a network node associated with another network. For example, in a DS scenario, UE 120 may send the CSI of the first network to a second network node 110-2, and / or UE 120 may send the CSI of the second network to a first network node 110-1.

[0132] As indicated above, Figure 6 This is provided as an example. Other examples are available with reference to [the relevant information]. Figure 6 The examples described are different.

[0133] Figure 7 This is a diagram illustrating example 700 associated with enhanced resource management for DC. (See diagram for example.) Figure 7 As shown, UE 120 can communicate with first network node 110-1 and second network node 110-2. In some aspects, first network node 110-1, second network node 110-2, and UE 120 can be part of a wireless network (e.g., wireless network 100). Figure 7Prior to the operations shown, UE 120 may have established radio connections with the first network node 110-1 and the second network node 110-2. In some aspects, for dual-connectivity communication with UE 120, the first network node 110-1 is the MN and the second network node 110-2 is the SN. In such examples, the first cell group associated with the first network node 110-1 may be an MCG and the second cell group associated with the second network node 110-2 may be an SCG. In some aspects, for dual-connectivity communication with UE 120, the second network node 110-2 is the MN and the first network node 110-1 is the SN. In such examples, the second cell group may be an MCG and the first cell group may be an SCG. In some aspects, the first network node 110-1 and the second network node 110-2 may be non-co-located.

[0134] In some aspects, such as in Figure 7 In Example 700, UE 120 may send, and at least one of first network node 110-1 or second network node 110-2 may receive, first information associated with the amount of data split across the first cell group and the second cell group. In such an example, UE 120 may communicate with first network node 110-1 via the first cell group and with second network node 110-2 via the second cell group, based on the amount of data split across the first cell group and the second cell group, at least in part based on the first information. In Example 700, the first information may include or be included therein an enhanced UAI. For example, the first information may include a UAI indicating UE preferences for the amount of data split across the first cell group and the second cell group. In some aspects, references Figure 7 The operations discussed can be performed without dynamically sharing UE resources across the first and second cell groups. In such an example, UE 120 may send a first message (e.g., enhanced UAI), and UE 120 may avoid sending a second message associated with sharing UE resources across the first and second cell groups. In some other aspects, refer to Figure 7 The operations discussed can be performed in conjunction with dynamically sharing UE resources across the first and second cell groups. For example, refer to... Figure 7 The operations discussed can be referenced. Figure 9 , Figure 10 or Figure 11 The discussed combination of operations. In such an example, UE 120 may send a first message (e.g., enhanced UAI), and UE 120 may also send a second message associated with sharing UE resources across a first cell group and a second cell group, as referenced. Figure 9 , Figure 10 or Figure 11 The discussion.

[0135] like Figure 7As shown by reference numeral 705, UE 120 can send and first network node 110-1 can receive UE capability information. For example, the UE can send and first network node 110-1 can receive a capability report including UE capability information. Additionally or alternatively, second network node 110-2 can receive UE capability information. In some examples, second network node 110-2 can receive UE capability information from first network node 110-1 (e.g., first network node 110-1 can forward UE capability information to second network node 110-2). In some other examples, second network node 110-2 can receive UE capability information from UE 120 (e.g., as a supplement or alternative to first network node 110-1 receiving UE capability information).

[0136] UE capability information may indicate one or more capabilities associated with a DC. For example, UE capability information may indicate whether UE120 supports (e.g., is capable of) DC communication. In some aspects, UE capability information may indicate one or more frequency band combinations for a DC supported by UE 120. In some aspects, UE capability information may indicate UE 120's capabilities for feature sets and / or maximum power in FR1 and FR2.

[0137] like Figure 7 As further illustrated by reference numeral 710, in some aspects, the first network node 110-1 and the second network node 110-2 may coordinate to determine the SCG configuration for UE 120. In some aspects, the MN (e.g., the first network node 110-1) and the SN (e.g., the second network node 110-2) may coordinate to determine the SCG configuration for UE 120 based at least in part on UE capability information. For example, the MN may supervise the resolution of dependencies between the MCG configuration and the SCG configuration of UE 120. The MN may determine the MCG configuration and a list of possible SCG configurations, and the MN may send the list of possible SCG configurations to the SN. The list of possible SCG configurations may include possible DC band combinations and / or feature sets based at least in part on UE capability information. In some examples, the SN may select an SCG configuration from the list of possible SCG configurations and report the selected SCG configuration to the MN. Alternatively, the SN may negotiate with the MN regarding the selection of the SCG configuration. For example, the SN can initiate modifications to the list of possible SCG configurations and indicate one or more desired SCG configurations (e.g., desired frequency band combinations and / or feature sets) outside the list of possible SCG configurations selected by the MN. The MN can then make the final determination of the SCG configuration.

[0138] like Figure 7As further illustrated by reference numeral 715, the first network node 110-1 can send and the UE 120 can receive configuration information. In some examples, the MN (e.g., the first network node 110-1) can send configuration information to the UE 120. In some examples, the UE 120 can receive configuration information from the SN or from both the MN and the SN. In some aspects, the UE 120 can receive configuration information via one or more RRC messages. Additionally or alternatively, the UE 120 can receive configuration information via system information (e.g., MIB and / or SIB, etc.), one or more MAC-CEs, and / or DCIs, etc.

[0139] In some aspects, the configuration information may indicate one or more candidate configuration and / or communication parameters. In some aspects, these one or more candidate configuration and / or communication parameters may be selected, activated, and / or deactivated by subsequent indications. For example, subsequent indications may select candidate configuration and / or communication parameters from the one or more candidate configuration and / or communication parameters. In some aspects, subsequent indications may include dynamic indications, such as one or more MAC-CE and / or one or more DCI messages, etc.

[0140] In some aspects, the configuration information can configure UE 120 for DC communication. For example, the configuration information may include MCG and SCG configurations for UE 120. In some examples, the configuration information may indicate the CC (or cell) in each cell group, the active BWP for the CC in each cell group, and / or the number of MIMO layers to be used for each cell group, etc. In some examples, the configuration information may configure how UE resources are allocated across MCG and SCG. For example, UE resources may include BB resources, RF resources (e.g., RF chains), and / or antennas for UE 120.

[0141] In some aspects, configuration information may configure UE 120 to perform channel measurements and report channel measurements. For example, configuration information may include configurations for one or more CSI-RS to be measured by UE 120 and configurations for one or more CSI reports to be sent by UE 120. In some aspects, configuration information may configure UE 120 to measure one or more first CSI-RS associated with a first cell group (e.g., MCG) and to measure one or more second CSI-RS associated with a second cell group (e.g., SCG). In such examples, configuration information may configure UE 120 to report the first CSI associated with the first cell group (e.g., MCG) to a first network node 110-1 (e.g., MN) and to report the second CSI associated with the second cell group (e.g., SCG) to a second network node 110-2 (e.g., SN).

[0142] like Figure 7As further illustrated by reference numeral 720, UE 120 can perform channel measurements on the MCG and SCG. For example, a first network node 110-1 can transmit one or more first CSI-RSs via a first cell group (e.g., MCG), and UE 120 can perform channel measurements on one or more first CSI-RSs. UE 120 can determine or derive a first CSI based at least in part on the channel measurements performed on one or more first CSI-RSs. The first CSI may include one or more estimates and / or measurements of channel conditions (e.g., downlink channel conditions) on UE channels to the first cell group (e.g., MCG). UE 120 can perform channel measurements for each CC of the first cell group, and the first CSI may include a CSI for each CC of the first cell group. A second network node can transmit one or more second CSI-RSs via a second cell group (e.g., SCG), and UE 120 can perform channel measurements on one or more second CSI-RSs. UE 120 can determine or derive a second CSI based at least in part on the channel measurements performed on one or more second CSI-RSs. The second CSI may include one or more estimates and / or measurements of channel conditions (e.g., downlink channel conditions) on UE channels to the second cell group (e.g., SCG). UE120 may perform channel measurements for each CC of the second cell group, and the second CSI may include CSI for each CC of the second cell group.

[0143] In some aspects, the first UE 120 may transmit and the first network node 110-1 may receive a first CSI. For example, UE 120 may transmit a first CSI report including the first CSI to the first network node 110-1. In some aspects, the first UE 120 may transmit and the second network node 110-2 may receive a second CSI. For example, UE 120 may transmit a second CSI report including the second CSI to the second network node 110-2.

[0144] like Figure 7As further illustrated by reference numeral 725, UE 120 may send, and at least one of the first network node 110-1 or the second network node 110-2 may receive, a UAI indicating preferences for splitting data across MCGs (e.g., the first cell group) and SCGs (e.g., the second cell group). For example, UE 120 may send a UAI message including a UAI indicating preferences for splitting data amounts across MCGs and SCGs. UE 120 may access channel conditions (e.g., the first CSI) between UE 120 and the MN on each of the CCs configured for the MCGs and channel conditions (e.g., the second CSI) between UE 120 and the SN on each of the CCs configured for the SCGs. In some aspects, UE 120 may determine preferences for how to split data across MCG and SCG resources (e.g., preferred splitting of data amounts between MCGs and SCGs) based at least in part on the channel conditions associated with the MCGs and SCGs. For example, UE 120 may determine, at least in part, a preference for which path (e.g., MCG or SCG) for which portion of the available data to be transmitted by UE 120 should be used, based on a first CSI associated with the MCG, a second CSI associated with the SCG, the total bandwidth available on each cell group (e.g., each tributary or path), and / or one or more configurations selected for UE 120 (e.g., the number of layers configured in the MCG and SCG). For example, UE 120 may determine a preferred path (e.g., MCG or SCG) for all or a portion of the data volume. In some examples, UE 120 may determine preferences to favor the use of cell groups with better channel conditions (e.g., MCG or SCG), such that more data is transmitted using cell groups with better channel conditions.

[0145] UE 120 may signal preferences for splitting data volumes across MCGs (e.g., the first cell group) and SCGs (e.g., the second cell group) via a UAI. In some aspects, the UAI may indicate a preferred splitting threshold for splitting data volumes across MCGs (e.g., the first cell group) and SCGs (e.g., the second cell group). That is, the UAI may include indications of specific preferred splitting thresholds to apply to splitting data across MCGs and SCGs. In some examples, the UAI may include indications of preferred paths for downlink or uplink data. In some other aspects, the UAI may indicate a request to increase or decrease a previously signaled splitting threshold for splitting data volumes across the first and second cell groups. For example, the UAI may include indications of whether to request an increase or decrease in a previously signaled splitting threshold, and instructions regarding cell group parameters (e.g., ...). cellGroupThe UAI indicates whether to transmit the maximum amount of data up to the split threshold via the MCG or SCG. In some aspects, the UAI may indicate preferences for upgrading / increasing one or more parameters configured for DC communications. For example, the UAI may include preferences for increasing the maximum bandwidth associated with a first cell group (e.g., MCG) or a second cell group (e.g., SCG), the maximum number of MIMO layers associated with a first cell group (e.g., MCG) or a second cell group (e.g., SCG), and / or the maximum number of cells (e.g., CC) associated with a first cell group (e.g., MCG) or a second cell group (e.g., MCG).

[0146] Due to the enhancements to legacy UAIs, the UAI described herein may be referred to as an "enhanced UAI." For example, unlike legacy UAIs, the UAI described herein enables UE 120 to indicate preferences for splitting data volumes across MCGs and SCGs and / or enables UE 120 to signal preferences for such increases. Furthermore, the UAI described herein can be used by UE 120 to change (e.g., add / upgrade) one or more parameters to enhance DC resource management (e.g., to increase throughput), rather than for power saving.

[0147] UE 120 may send UAI messages, including the UAI, to the MN, SN, or both. In some respects, because the UAI message affects both the MN / MCG and SN / SCG configuration and scheduling decisions, the UAI message may terminate at the MN even if UE 120 sends it to the SN. For example, if UE 120 sends the UAI message to the SN instead of the MN, the SN may pass / forward the UAI message to the MN via the backhaul interface.

[0148] like Figure 7As further illustrated by reference numeral 730, the first network node 110-1 and / or the second network node 110-2 can transmit, and the UE 120 can receive, an indication of a splitting threshold. The splitting threshold can indicate the amount of data to be split across a first cell group (e.g., MCG) and a second cell group (e.g., SCG) for uplink and / or downlink communications. In some aspects, the indication of the splitting threshold can be at least partially based on a UAI indication of a preference for splitting the amount of data across the first and second cell groups. In some examples, the first network node 110-1 or the second network node 110-2 can determine the splitting threshold by selecting a preferred splitting threshold indicated in the UAI or otherwise at least partially based on the preferred splitting threshold indication in the UAI. In some examples, the splitting threshold can be at least partially based on the splitting of network resources across the first and second cell groups determined by the first network node 110-1 or the second network node 110-2 at least partially based on the preferred splitting threshold indication in the UAI. In some other examples, the first network node 110-1 or the second network node 110-2 may determine the split threshold by increasing or decreasing the previously signaled split threshold, at least in part, based on a request to increase or decrease the previously signaled split threshold as indicated in the UAI. In some other examples, the first network node 110-1 and / or the second network node 110-2 may indicate one or more updated (e.g., added) parameters for DC communication, at least in part, based on a request to upgrade / add one or more parameters included in the UAI.

[0149] like Figure 7 As further illustrated by reference numeral 735, UE 120 can communicate with first network node 110-1 and second network node 110-2 via the first cell group and the second cell group, respectively, according to an indication of a splitting threshold (e.g., an indication of splitting data across the first cell group and the second cell group). In some examples, UE 120 can send uplink communication to first network node 110-1 (e.g., MN) via the first cell group (e.g., MCG) and to second network node 110-2 (e.g., SN) via the second cell group, according to the indication of the splitting threshold. For example, UE 120 can send a portion of the data volume via one of the first cell group or the second cell group until the splitting threshold is reached, and send the remaining portion of the data volume via the other of the first cell group or the second cell group.

[0150] In some examples, based on an indicated splitting threshold, a first network node 110-1 may send downlink communication to UE 120 via a first cell group, and a second network node 110-2 may send downlink communication to UE 120 via a second cell group. The first network node 110-1 and the second network node 110-2 may split downlink data between the first and second cell groups according to the splitting threshold. UE 120 may receive downlink communication split across the first and second cell groups according to the indicated splitting threshold. For example, UE 120 may receive a portion of the downlink data via either the first or second cell group until the splitting threshold is reached, and the remaining portion of the downlink data via the other cell group.

[0151] For reference Figure 7 As discussed, UE 120 can determine its preference for splitting data amounts across MCGs and SCGs based at least in part on the channel conditions (e.g., first CSI and second CSI) of UE 120 on the CC of MCGs and SCGs. In some examples, UE 120 can determine preferences to favor the use of cell groups (e.g., MCGs or SCGs) with better channel conditions, thereby enabling the transmission of more data using cell groups with better channel conditions. UE 120 can transmit preferences to MN and / or SN via UAI, and MN or SN can determine the splitting ratio based at least in part on the preferences indicated via UAI. This enhances / increases downlink and uplink throughput of DC communications. Furthermore, because UE 120 determines preferences through concurrent signaling rather than relying on CSI exchanges between MN and SN, this is consistent with the above references. Figure 6 Compared to the operation discussed, this reduces the backhaul signaling overhead between the MN and SN, and also reduces the latency caused by the exchange of CSI information between the MN and SN.

[0152] Despite the above reference Figure 7 The operations discussed are described in conjunction with DC, but the above references... Figure 7The operations discussed can be similarly applied to a DS scenario. In a DS scenario, UE 120 can independently connect to two networks. For example, the two networks may be associated with the same or different operators. UE 120 may have two SIMs (e.g., two SIM cards), with each SIM used to connect to a different network. In a DS scenario, a first network node 110-1 may be associated with a first network, and a second network node 110-2 may be associated with a second network. UE 120 may connect to the first network via a first link with the first network node 110-1 and to the second network via a second link with the second network node 110-2. In such an example, UE 120 may determine a preference for splitting data volume between the first and second networks, and UE 120 may send this preference to the first network node 110-1 and / or the second network node 110-2, as referenced above. Figure 7 As described.

[0153] As indicated above, Figure 7 This is provided as an example. Other examples are available with reference to [the relevant information]. Figure 7 The examples described are different.

[0154] Figure 8 This is a diagram illustrating example 800 associated with enhanced resource management for DC. For example... Figure 8 As shown, UE 120 can communicate with first network node 110-1 and second network node 110-2. In some aspects, first network node 110-1, second network node 110-2, and UE 120 can be part of a wireless network (e.g., wireless network 100). Figure 8 Prior to the operations shown, UE 120 may have established radio connections with the first network node 110-1 and the second network node 110-2. In some aspects, for dual-connectivity communication with UE 120, the first network node 110-1 is the MN and the second network node 110-2 is the SN. In such examples, the first cell group associated with the first network node 110-1 may be an MCG and the second cell group associated with the second network node 110-2 may be an SCG. In some aspects, for dual-connectivity communication with UE 120, the second network node 110-2 is the MN and the first network node 110-1 is the SN. In such examples, the second cell group may be an MCG and the first cell group may be an SCG. In some aspects, the first network node 110-1 and the second network node 110-2 may be non-co-located.

[0155] In some aspects, such as in Figure 8In Example 800, UE 120 may transmit, and at least one of first network node 110-1 or second network node 110-2 may receive, first information associated with the amount of data split across the first cell group and the second cell group. In such an example, UE 120 may communicate with first network node 110-1 via the first cell group and with second network node 110-2 via the second cell group, based at least in part on the split of the data amount across the first cell group and the second cell group. In Example 800, the first information may indicate that the split of the data amount across the first cell group and the second cell group will be used for DC communication (e.g., uplink communication and / or downlink communication). For example, the first information may include an indication of a splitting threshold determined by UE 120 that will be applied to the split data across the first cell group and the second cell group (e.g., indicating the splitting ratio of the data amount split across the first cell group and the second cell group). In some aspects, reference is made to... Figure 8 The operations discussed can be performed without dynamically sharing UE resources across the first and second cell groups. In such an example, UE 120 may send first information (e.g., an indication of a splitting threshold), and UE 120 may avoid sending second information associated with sharing UE resources across the first and second cell groups. In some other aspects, refer to Figure 8 The operations discussed can be performed in conjunction with dynamically sharing UE resources across the first and second cell groups. For example, refer to... Figure 8 The operations discussed can be referenced in this article. Figure 9 , Figure 10 or Figure 11 The discussed combination of operations. In such an example, UE 120 may send first information (e.g., an indication of a splitting threshold), and UE 120 may also send second information associated with sharing UE resources across a first cell group and a second cell group, as referenced. Figure 9 , Figure 10 or Figure 11 The discussion.

[0156] like Figure 8As shown by reference numeral 805, UE 120 can send and first network node 110-1 can receive UE capability information. For example, the UE can send and first network node 110-1 can receive a capability report including UE capability information. Additionally or alternatively, second network node 110-2 can receive UE capability information. In some examples, second network node 110-2 can receive UE capability information from first network node 110-1 (e.g., first network node 110-1 can forward UE capability information to second network node 110-2). In some other examples, second network node 110-2 can receive UE capability information from UE 120 (e.g., as a supplement or alternative to first network node 110-1 receiving UE capability information).

[0157] UE capability information may indicate one or more capabilities associated with a DC. For example, UE capability information may indicate whether UE120 supports (e.g., is capable of) DC communication. In some aspects, UE capability information may indicate one or more frequency band combinations for a DC supported by UE 120. In some aspects, UE capability information may indicate UE 120's capabilities for characteristic sets and / or maximum power in FR1 and FR2. In some aspects, UE capability information may indicate UE 120's capabilities for determining or selecting the splitting (e.g., splitting threshold) of data volume across cell groups (e.g., MCG and SCG) for DC communication.

[0158] like Figure 8 As further illustrated by reference numeral 810, in some aspects, the first network node 110-1 and the second network node 110-2 may coordinate to determine the SCG configuration for UE 120. In some aspects, the MN (e.g., the first network node 110-1) and the SN (e.g., the second network node 110-2) may coordinate to determine the SCG configuration for UE 120 based at least in part on UE capability information. For example, the MN may supervise the resolution of dependencies between the MCG configuration and the SCG configuration of UE 120. The MN may determine the MCG configuration and a list of possible SCG configurations, and the MN may send the list of possible SCG configurations to the SN. The list of possible SCG configurations may include possible DC band combinations and / or feature sets based at least in part on UE capability information. In some examples, the SN may select an SCG configuration from the list of possible SCG configurations and report the selected SCG configuration to the MN. Alternatively, the SN may negotiate with the MN regarding the selection of the SCG configuration. For example, the SN can initiate modifications to the list of possible SCG configurations and indicate one or more desired SCG configurations (e.g., desired frequency band combinations and / or feature sets) outside the list of possible SCG configurations selected by the MN. The MN can then make the final determination of the SCG configuration.

[0159] like Figure 8 As further illustrated by reference numeral 815, the first network node 110-1 can send and the UE 120 can receive configuration information. In some examples, the MN (e.g., the first network node 110-1) can send configuration information to the UE 120. In some examples, the UE 120 can receive configuration information from the SN or from both the MN and the SN. In some aspects, the UE 120 can receive configuration information via one or more RRC messages. Additionally or alternatively, the UE 120 can receive configuration information via system information (e.g., MIB and / or SIB, etc.), one or more MAC-CEs, and / or DCIs, etc.

[0160] In some aspects, the configuration information may indicate one or more candidate configuration and / or communication parameters. In some aspects, these one or more candidate configuration and / or communication parameters may be selected, activated, and / or deactivated by subsequent indications. For example, subsequent indications may select candidate configuration and / or communication parameters from the one or more candidate configuration and / or communication parameters. In some aspects, subsequent indications may include dynamic indications, such as one or more MAC-CE and / or one or more DCI messages, etc.

[0161] In some aspects, the configuration information can configure UE 120 for DC communication. For example, the configuration information may include MCG and SCG configurations for UE 120. In some examples, the configuration information may indicate the CC (or cell) in each cell group, the active BWP for the CC in each cell group, and / or the number of MIMO layers to be used for each cell group, etc. In some examples, the configuration information may configure how UE resources are allocated across MCG and SCG. For example, UE resources may include BB resources, RF resources (e.g., RF chains), and / or antennas for UE 120.

[0162] In some aspects, configuration information may configure UE 120 to perform channel measurements and report channel measurements. For example, configuration information may include configurations for one or more CSI-RS to be measured by UE 120 and configurations for one or more CSI reports to be sent by UE 120. In some aspects, configuration information may configure UE 120 to measure one or more first CSI-RS associated with a first cell group (e.g., MCG) and to measure one or more second CSI-RS associated with a second cell group (e.g., SCG). In such examples, configuration information may configure UE 120 to report the first CSI associated with the first cell group (e.g., MCG) to a first network node 110-1 (e.g., MN) and to report the second CSI associated with the second cell group (e.g., SCG) to a second network node 110-2 (e.g., SN).

[0163] In some aspects, the configuration information may include configuration information associated with splitting (e.g., splitting threshold) the data volume across a first cell group (e.g., MCG) and a second cell group (e.g., SCG). That is, the configuration information may configure the UE 120 to select a split of the data volume across the MCG and SCG. For example, the configuration information may configure one or more parameters and / or conditions to facilitate the UE 120's selection of a split (e.g., splitting threshold) and / or constrain the solution (e.g., the selected splitting threshold) within the boundaries of the control network. In some examples, the configuration information associated with selecting a split may define (or indicate) the metrics and / or algorithms used by the UE 120 to select the splitting threshold. For example, the configuration information may indicate one or more inputs to the algorithm (e.g., how to derive the channel estimate to be used, which reference signals to use to derive the channel estimate, how to perform TD and / or FD filtering of the channel estimate and / or which ranks, number of layers, and / or modulation and decoding schemes (MCS) to consider, etc.). For example, the metric could be indicated as one or more relevant thresholds to trigger a change in the split threshold (e.g., if the filtered channel of the SCG is better than that of the MCG). X (If dB, then a change in the split threshold is triggered), and other examples. For example, determining that the filtered channel of a cell group (e.g., MCG or SCG) is superior to the filtered channel of another cell group may be based at least in part on the fact that the filtered channel of that cell group has a higher RSRP and / or a higher SINR than the filtered channel of the other cell group. In some aspects, the configuration information associated with the split selection may be determined by MN, SN, or both MN and SN (e.g., involving negotiation and / or handshake), and the configuration information associated with the split selection may be sent to UE 120 by MN, SN, or both MN and SN. For example, the configuration information associated with the split selection may be signaled via Layer 3 (L3) signaling (e.g., one or more RRC messages), Layer 2 (L2) signaling (e.g., one or more MAC-CEs), and / or Layer 1 (L1) signaling (e.g., DCI).

[0164] like Figure 8As further illustrated by reference numeral 820, UE 120 can perform channel measurements on the MCG and SCG. For example, the first network node 110-1 can transmit one or more first CSI-RSs via the first cell group (e.g., MCG), and UE 120 can perform channel measurements on one or more first CSI-RSs. UE 120 can determine or derive the first CSI based at least in part on the channel measurements performed on one or more first CSI-RSs. The first CSI can include one or more channel estimates and / or measurements of channel conditions (e.g., downlink channel conditions) on UE channels to the first cell group (e.g., MCG). For example, the first CSI can include one or more channel estimates indicated in the configuration information, which will be used by UE 120 to select a split (e.g., a split threshold) of the data volume across the first cell group and the second cell group. UE 120 can perform channel measurements for each CC of the first cell group, and the first CSI can include a CSI for each CC of the first cell group.

[0165] The second network node may transmit one or more second CSI-RSs via a second cell group (e.g., SCG), and the UE 120 may perform channel measurements on the one or more second CSI-RSs. The UE 120 may determine or derive the second CSI based at least in part on the channel measurements performed on the one or more second CSI-RSs. The second CSI may include one or more channel estimates and / or measurements of channel conditions (e.g., downlink channel conditions) on UE channels to the second cell group (e.g., SCG). For example, the second CSI may include one or more channel estimates indicated in the configuration information, which will be used by the UE 120 to select a split (e.g., a split threshold) of the data volume across the first and second cell groups. The UE 120 may perform channel measurements for each CC of the second cell group, and the second CSI may include a CSI for each CC of the second cell group.

[0166] In some aspects, the first UE 120 may transmit and the first network node 110-1 may receive a first CSI. For example, UE 120 may transmit a first CSI report including the first CSI to the first network node 110-1. In some aspects, the first UE 120 may transmit and the second network node 110-2 may receive a second CSI. For example, UE 120 may transmit a second CSI report including the second CSI to the second network node 110-2.

[0167] like Figure 8Furthermore, as shown by reference numeral 825, UE 120 may select a splitting threshold. In some aspects, UE 120 may select the amount of data to be split across a first cell group (e.g., MCG) and a second cell group (e.g., SCG) for uplink and / or downlink communication. For example, UE 120 may select a splitting threshold to apply to the amount of data to be split across the first cell group (e.g., MCG) and the second cell group (e.g., SCG) (e.g., splitting data to be transmitted across MCG and SCG). In some aspects, UE 120 may select a splitting threshold to apply to both uplink and downlink communication. In some examples, UE 120 may select a preferred path (e.g., MCG or SCG) for downlink or uplink communication. In some examples, UE 120 may select a splitting threshold to favor the use of a cell group with better channel conditions (e.g., MCG or SCG), allowing more data to be transmitted using the cell group with better channel conditions.

[0168] In some aspects, UE 120 may determine the split threshold based at least in part on channel estimates associated with a first cell group (e.g., MCG) and channel estimates associated with a second cell group (e.g., SCG). For example, the channel estimates associated with the first cell group may be included in a first CSI, and the channel estimates associated with the second cell group may be included in a second CSI. In some examples, the channel estimates associated with the MCG and SCG may be defined or indicated in configuration information (e.g., split threshold) associated with the split selection. In some examples, UE 120 may select a split ratio to favor the use of a cell group with better channel conditions (e.g., MCG or SCG), allowing more data to be transmitted using the cell group with better channel conditions. In some aspects, UE 120 may use a metric or algorithm defined in the configuration information to select / determine the split threshold. In some aspects, UE 120 may trigger the selection of a split threshold by combining the satisfaction of triggering conditions for changing the split threshold. For example, triggering conditions for changing the split threshold may be defined in configuration information (e.g., split threshold) associated with the split selection.

[0169] like Figure 8As further illustrated by reference numeral 830, UE 120 can send, and at least one of the first network node 110-1 or the second network node 110-2 can receive, an indication of a splitting threshold selected by UE 120. For example, the indication of the splitting threshold can indicate the splitting of the amount of data to be applied to uplink and downlink communications across a first cell group (e.g., MCG) and a second cell group (e.g., SCG). In some aspects, UE 120 can send the indication of the splitting threshold via L3 signaling (e.g., RRC message), L2 signaling (e.g., MAC-CE), or L1 signaling (e.g., UCI). In some aspects, UE 120 can send the indication of the splitting threshold to MN, SN, or both MN and SN.

[0170] like Figure 8 Furthermore, as shown by reference numeral 835, the first network node 110-1 can send, and the UE 120 can receive, an acknowledgment of the indication of the split threshold. Additionally or alternatively, as shown by reference numeral 835a, the second network node 110-2 can send, and the UE 120 can receive, an acknowledgment of the indication of the split threshold. In some aspects, the UE 120 can apply the split threshold selected by the UE 120 (e.g., for uplink and / or downlink communication) in conjunction with the received acknowledgment.

[0171] like Figure 8 As further illustrated by reference numeral 840, UE 120 may communicate with first network node 110-1 and second network node 110-2 via the first cell group and the second cell group, respectively, according to an indication of a splitting threshold selected by UE 120 (e.g., an indication of splitting the data volume across the first cell group and the second cell group selected by UE 120). In some examples, UE 120 may send uplink communication to first network node 110-1 (e.g., MN) via the first cell group (e.g., MCG) and to second network node 110-2 (e.g., SN) via the second cell group, according to the indication of the splitting threshold. For example, UE 120 may send a portion of the data volume via one of the first cell group or the second cell group until the splitting threshold is reached, and send the remaining portion of the data volume via the other of the first cell group or the second cell group. In some aspects, the BSR requesting scheduling of uplink communication to be sent by UE 120 may be based on the splitting threshold selected by UE 120. For example, UE 120 may send a BSR to at least one of the first network node 110-1 or the second network node 110-2 based on a splitting threshold selected by UE 120. In this way, the splitting threshold selected by UE 120 (and the corresponding splitting ratio resulting from the application of the splitting threshold selected by UE 120) can be implemented for uplink communication.

[0172] In some examples, based on an indication of a splitting threshold selected by UE 120, a first network node 110-1 may send downlink communication to UE 120 via a first cell group, and a second network node 110-2 may send downlink communication to UE 120 via a second cell group. The first network node 110-1 and the second network node 110-2 may split downlink data between the first and second cell groups according to the splitting threshold. UE 120 may receive downlink communication split across the first and second cell groups according to the indicated splitting threshold. For example, UE 120 may receive a portion of the downlink data via one of the first or second cell groups until the splitting threshold is reached, and the remaining portion of the downlink data via the other of the first or second cell groups. In some examples, the splitting threshold selected by UE 120 may not be enforceable for downlink communication sent by the first network node 110-1 and the second network node 110-2. However, by using the splitting threshold selected by UE 120 for downlink communication, the first network node 110-1 and the second network node 110-2 reduce the waste of network resources for downlink communication to UE 120 on links with poor quality when UE 120 can be better served on other links.

[0173] As referenced above Figure 8 As discussed, UE 120 may select a splitting threshold to apply to the amount of data split across MCG and SCG based at least in part on the channel conditions (e.g., first CSI and second CSI) of UE 120 on the CC of MCG and SCG. In some examples, UE 120 may select a splitting threshold to favor the use of cell groups with better channel conditions (e.g., MCG or SCG), allowing more data to be transmitted using cell groups with better channel conditions. UE 120 may send an indication of the selected splitting threshold to MN and / or SN. This can enhance / increase downlink and uplink throughput of DC communication. Furthermore, because the determination of the splitting threshold does not involve significant coordination between MN and SN, it is consistent with the above references. Figure 6 and Figure 7 Compared to the operations discussed, this reduces latency and can further increase throughput.

[0174] Despite the above reference Figure 8 The operations discussed are described in conjunction with DC, but the above references... Figure 8The operations discussed can be similarly applied to a DS scenario. In a DS scenario, UE 120 can independently connect to two networks. For example, the two networks may be associated with the same or different operators. UE 120 may have two SIMs (e.g., two SIM cards), with each SIM used to connect to a different network. In a DS scenario, a first network node 110-1 may be associated with a first network, and a second network node 110-2 may be associated with a second network. UE 120 may be connected to the first network via a first link with the first network node 110-1 and to the second network via a second link with the second network node 110-2. In such an example, UE 120 may determine a splitting threshold for splitting the amount of data between the first and second networks, and UE 120 may send an indication of the splitting threshold to the first network node 110-1 and / or the second network node 110-2, as referenced above. Figure 8 As described.

[0175] As indicated above, Figure 8 This is provided as an example. Other examples are available with reference to [the relevant information]. Figure 8 The examples described are different.

[0176] Figure 9 This is a diagram illustrating example 900 associated with enhanced resource management for a DC with dynamically shared UE resources. (See diagram 900 for example 900.) Figure 9 As shown, UE 120 can communicate with first network node 110-1 and second network node 110-2. In some aspects, first network node 110-1, second network node 110-2, and UE 120 can be part of a wireless network (e.g., wireless network 100). Figure 9 Prior to the operations shown, UE 120 may have established radio connections with the first network node 110-1 and the second network node 110-2. In some aspects, for dual-connectivity communication with UE 120, the first network node 110-1 is the MN and the second network node 110-2 is the SN. In such examples, the first cell group associated with the first network node 110-1 may be an MCG and the second cell group associated with the second network node 110-2 may be an SCG. In some aspects, for dual-connectivity communication with UE 120, the second network node 110-2 is the MN and the first network node 110-1 is the SN. In such examples, the second cell group may be an MCG and the first cell group may be an SCG. In some aspects, the first network node 110-1 and the second network node 110-2 may be non-co-located.

[0177] In some aspects, such as in Figure 9In Example 900, UE 120 may transmit, and at least one of the first network node 110-1 or the second network node 110-2 may receive, second information associated with shared UE resources (e.g., baseband resources, RF resources, and / or the antenna of UE 120) across the first and second cell groups. In such an example, UE 120 may communicate with the first network node 110-1 via the first cell group and with the second network node 110-2 via the second cell group, based at least in part on the allocation of UE resources across the first and second cell groups according to the second information.

[0178] In Example 900, the second information may include UE capability information or be included in the UE capability information. For example, the second information may include UE capability information associated with the ability of UE 120 to share UE resources across a first cell group and a second cell group. In some aspects, references Figure 9 The operations discussed can be performed without managing the splitting of data across the first and second cell groups, as referenced above. Figures 6 to 8 The discussion is ongoing. In some other respects, refer to... Figure 9 The operations discussed can be performed in conjunction with the management of data splitting across the first and second cell groups. For example, refer to... Figure 9 The operations discussed can be referenced. Figure 6 , Figure 7 or Figure 8 The combination of operations discussed.

[0179] like Figure 9 As shown by reference numeral 905, UE 120 can send and first network node 110-1 can receive UE capability information. For example, the UE can send and first network node 110-1 can receive a capability report including UE capability information. Additionally or alternatively, as shown by reference numeral 905a, second network node 110-2 can receive UE capability information. In some examples, second network node 110-2 can receive UE capability information from first network node 110-1 (e.g., first network node 110-1 can forward UE capability information to second network node 110-2). In some other examples, second network node 110-2 can receive UE capability information from UE 120 (e.g., as a supplement or alternative to first network node 110-1 receiving UE capability information).

[0180] UE capability information may indicate one or more capabilities associated with a DC. For example, UE capability information may indicate whether UE120 supports (e.g., is capable of) DC communication. In some aspects, UE capability information may indicate one or more frequency band combinations for a DC supported by UE 120. In some aspects, UE capability information may indicate UE 120's capabilities for feature sets and / or maximum power in FR1 and FR2.

[0181] In some aspects, UE capability information may include capability information associated with the ability of UE 120 to share UE resources (e.g., baseband resources, RF resources, and / or antennas, etc.) across a first cell group and a second cell group (e.g., sharing UE resources for communication via the first cell group and the second cell group). In some aspects, the capability information associated with the ability of UE 120 to share UE resources may include multiple shared capability profiles supported by UE 120. For example, each shared capability profile may correspond to a different sharing state (e.g., different allocations of UE resources for communication via different cell groups).

[0182] like Figure 9 As further illustrated by reference numeral 910, in some aspects, the first network node 110-1 and the second network node 110-2 may coordinate to determine the SCG configuration for UE 120. In some aspects, the MN (e.g., the first network node 110-1) and the SN (e.g., the second network node 110-2) may coordinate to determine the SCG configuration for UE 120 based at least in part on UE capability information. For example, the MN may supervise the resolution of dependencies between the MCG configuration and the SCG configuration of UE 120. The MN may determine the MCG configuration and a list of possible SCG configurations, and the MN may send the list of possible SCG configurations to the SN. The list of possible SCG configurations may include possible DC band combinations and / or feature sets based at least in part on UE capability information. In some examples, the SN may select an SCG configuration from the list of possible SCG configurations and report the selected SCG configuration to the MN. Alternatively, the SN may negotiate with the MN regarding the selection of the SCG configuration. For example, the SN can initiate modifications to the list of possible SCG configurations and indicate one or more desired SCG configurations (e.g., desired frequency band combinations and / or feature sets) outside the list of possible SCG configurations selected by the MN. The MN can then make the final determination of the SCG configuration.

[0183] like Figure 9As further illustrated by reference numeral 915, the first network node 110-1 can send and the UE 120 can receive configuration information. In some examples, the MN (e.g., the first network node 110-1) can send configuration information to the UE 120. In some examples, the UE 120 can receive configuration information from the SN or from both the MN and the SN. In some aspects, the UE 120 can receive configuration information via one or more RRC messages. Additionally or alternatively, the UE 120 can receive configuration information via system information (e.g., MIB and / or SIB, etc.), one or more MAC-CEs, and / or DCIs, etc.

[0184] In some aspects, the configuration information may indicate one or more candidate configuration and / or communication parameters. In some aspects, these one or more candidate configuration and / or communication parameters may be selected, activated, and / or deactivated by subsequent indications. For example, subsequent indications may select candidate configuration and / or communication parameters from the one or more candidate configuration and / or communication parameters. In some aspects, subsequent indications may include dynamic indications, such as one or more MAC-CE and / or one or more DCI messages, etc.

[0185] In some aspects, configuration information can be used to configure UE 120 for DC communication. For example, configuration information may include MCG and SCG configurations for UE 120. In some examples, configuration information may indicate the CC (or cell) in each cell group, the active BWP for the CC in each cell group, and / or the number of MIMO layers to be used for each cell group, etc.

[0186] In some aspects, configuration information may configure UE 120 to perform channel measurements and report channel measurements. For example, configuration information may include configuration for one or more CSI-RS to be measured by UE 120 and configuration for one or more CSI reports to be sent by UE 120. In some aspects, configuration information may configure UE 120 to measure one or more first CSI-RS associated with a first cell group (e.g., MCG) and to measure one or more second CSI-RS associated with a second cell group (e.g., SCG). In such examples, configuration information may configure UE 120 to report the first CSI associated with the first cell group (e.g., MCG) to a first network node 110-1 (e.g., MN) and to report the second CSI associated with the second cell group (e.g., SCG) to a second network node 110-2 (e.g., SN).

[0187] In some aspects, the configuration information may indicate a set of candidate allocations for UE resources. Each candidate allocation in the set may correspond to a corresponding possible allocation of UE resources (e.g., BB resources, RF resources, and / or antennas of UE 120) across MCG and SCG. The set of candidate allocations may be based, at least in part, on multiple shared capability profiles indicated in the UE capability information. For example, each candidate allocation in the set may correspond to a shared capability profile supported by UE 120. In some aspects, the configuration information may indicate a mapping between each candidate allocation in the set and a corresponding set of parameters to be used for that candidate allocation. For example, the corresponding set of parameters mapped to a candidate allocation may include parameters such as SRS resources, CSI feedback, and / or the size and / or format of the DCI to be monitored. In some aspects, the configuration information may indicate an initial or default allocation of UE resources selected from the set of candidate allocations.

[0188] like Figure 9 As further illustrated by reference numeral 920, UE 120 can perform channel measurements on the MCG and SCG. For example, a first network node 110-1 can transmit one or more first CSI-RSs via a first cell group (e.g., MCG), and UE 120 can perform channel measurements on one or more first CSI-RSs. UE 120 can determine or derive a first CSI based at least in part on the channel measurements performed on one or more first CSI-RSs. The first CSI may include one or more estimates and / or measurements of channel conditions (e.g., downlink channel conditions) on UE channels to the first cell group (e.g., MCG). UE 120 can perform channel measurements for each CC of the first cell group, and the first CSI may include a CSI for each CC of the first cell group. A second network node can transmit one or more second CSI-RSs via a second cell group (e.g., SCG), and UE 120 can perform channel measurements on one or more second CSI-RSs. UE 120 can determine or derive a second CSI based at least in part on the channel measurements performed on one or more second CSI-RSs. The second CSI may include one or more estimates and / or measurements of channel conditions (e.g., downlink channel conditions) on UE channels to the second cell group (e.g., SCG). UE120 may perform channel measurements for each CC of the second cell group, and the second CSI may include CSI for each CC of the second cell group.

[0189] like Figure 9As further illustrated by reference numeral 925, UE 120 can transmit and first network node 110-1 can receive a first CSI. For example, UE 120 can transmit a first CSI report including the first CSI to first network node 110-1. The first CSI is associated with UE 120 and a first cell group (e.g., MCG). That is, the first CSI indicates to first network node 110-1 the channel conditions of the downlink channel (e.g., the UE channel to the first cell group) between first network node 110-1 and UE 120. In some aspects, UE 120 can transmit the first CSI at least in part based on CSI report configuration included in configuration information. In some aspects, UE 120 can transmit the first CSI in conjunction with specific settings that include a request received from first network node 110-1 or a CSI configured to be associated with coordinating the sharing of UE resources. In some other examples, while maintaining downlink / uplink reciprocity between UE 120 and the first network node 110-1, the first network node 110-1 can determine the channel condition of the downlink channel between the first network node 110-1 and UE 120 via uplink channel probing.

[0190] like Figure 9 As further illustrated by reference numeral 930, UE 120 can transmit and second network node 110-2 can receive a second CSI. For example, UE 120 can transmit a second CSI report including the second CSI to second network node 110-2. The second CSI is associated with UE 120 and a second cell group (e.g., SCG). That is, the second CSI indicates to second network node 110-2 the channel conditions of the downlink channel (e.g., the UE channel to the second cell group) between second network node 110-2 and UE 120. In some aspects, UE 120 can transmit the second CSI at least in part based on CSI report configuration included in configuration information. In some aspects, UE 120 can transmit the second CSI in conjunction with specific settings that include a request received from second network node 110-2 or a CSI configured to be associated with coordinating the sharing of UE resources. In some other examples, while maintaining downlink / uplink reciprocity between UE 120 and the second network node 110-2, the second network node 110-2 can determine the channel condition of the downlink channel between the second network node 110-2 and UE 120 via uplink channel probing.

[0191] like Figure 9As further shown by reference numeral 935, the first network node 110-1 and / or the second network node 110-2 can communicate the CSI received from the UE 120, and the first network node 110-1 and / or the second network node 110-2 can determine changes in the allocation of UE resources (e.g., baseband resources, RF resources, and / or antennas, etc.) across the first cell group (e.g., MCG) and the second cell group (e.g., SCG).

[0192] In some respects, the MN and SN can exchange their local CSIs (e.g., the CSI associated with the MCG and the CSI associated with the SCG). For example, the first network node 110-1 can send a first CSI to the second network node 110-2, and the second network node 110-2 can send a second CSI to the first network node 110-1. In some other respects, one of the MN or SN can send a local CSI received from the UE 120 to the other of the MN or SN. In some examples, the first network node 110-1 can obtain a second CSI from the second network node 110-2 (e.g., the second network node 110-2 can send a second CSI to the first network node 110-1). In some other examples, the second network node 110-2 can obtain a first CSI from the first network node 110-1 (e.g., the first network node 110-1 can send a first CSI to the second network node 110-2). In some aspects, the CSI sent by the MN (e.g., the first network node 110-1) and / or the SN (e.g., the second network node 110-2) may include information identifying UE 120 and each serving cell of UE 120 (e.g., information that associates the CSI with UE 120 and each serving cell of UE 120) or be sent along with that information. In some other aspects, UE 120 may be configured to report the CSI of one cell group (or portions of the CSI, such as CQI, PMI, or L1-RSRP, etc.) to another cell group. For example, UE 120 may send a second CSI to both the second cell group (e.g., SCG) and the first cell group (e.g., MCG). In such examples, it may not be necessary for the first network node 110-1 (e.g., MN) and the second network node 110-2 (e.g., SN) to exchange CSIs.

[0193] The first network node 110-1 and / or the second network node 110-2 may determine changes to the allocation of UE resources to be applied by UE 120 across MCG and SCG. For example, the first network node 110-1 and / or the second network node 110-2 may determine the change from a previous allocation of UE resources across the first and second cell groups to a new allocation of UE resources across the first and second cell groups, based at least in part on UE capability information (e.g., supported possible allocations indicated in the UE capability information), a first CSI, and a second CSI. In some aspects, the first network node 110-1 and / or the second network node 110-2 may select the new allocation of UE resources from a set of candidate allocations indicated in the configuration information. For example, the previous allocation may correspond to a first candidate allocation in the allocation set, and the new allocation may correspond to a second candidate allocation in the allocation set.

[0194] In some aspects, either the MN or the SN can determine the change in the allocation of UE resources. In some examples, the first network node 110-1 can determine the change in the allocation of UE resources. In such examples, the first network node 110-1 can obtain a second CSI from the second network node 110-2, and the first network node 110-1 can determine the change in the allocation of UE resources across the first cell group and the second cell group based at least on the first CSI (received from UE 120) and the second CSI. In some other examples, the second network node 110-2 can determine the change in the allocation of UE resources. In such examples, the second network node 110-2 can obtain a first CSI from the first network node 110-1, and the second network node 110-2 can determine the change in the allocation of UE resources based at least on the first CSI and the second CSI (received from UE 120). In some aspects, the MN and SN can coordinate to determine the change in the allocation of UE resources. For example, the first network node 110-1 and the second network node 110-2 may exchange CSI information and then perform negotiation and / or handshake communications to determine changes in the allocation of UE resources based at least in part on the first and second CSI information. In some examples, the first network node 110-1 and the second network node 110-2 may determine changes in the allocation of UE resources to increase the allocation of UE resources (e.g., baseband resources, RF resources, and / or antennas, etc.) to cell groups (e.g., MCG or SCG) with better channel conditions.

[0195] In some aspects, UE 120 can provide relevant feedback (e.g., second CSI) targeting either the SN (e.g., second network node 110-2) or the MN (e.g., first network node 110-1) and the SN. In such an example, the MN (e.g., first network node 110-1) can determine a change in the allocation of UE resources and then notify the SN (e.g., second network node 110-2) of the changes in settings associated with the change in the allocation of UE resources. This can reduce latency caused during CSI exchange, negotiation, and handshake across the MN and SN.

[0196] like Figure 9 As further illustrated by reference numeral 940, the first network node 110-1 can send, and the UE 120 can receive, an indication of a change in the allocation of UE resources across the first and second cell groups. Additionally or alternatively, as shown by reference numeral 940a, the second network node 110-2 can send, and the UE 120 can receive, an indication of a change in the allocation of UE resources across the first and second cell groups. In some examples, the indication of a change in the allocation of UE resources may be sent to the UE 120 via the first cell group (e.g., from the first network node 110-1), via the second cell group (e.g., from the second network node 110-2), or via both the first and second cell groups. In some aspects, the indication of a change in the allocation of UE resources may include an indication of a candidate allocation in the candidate allocation set indicated in the configuration information corresponding to the new allocation. For example, the indication of a change in the allocation of UE resources may indicate a change from a first candidate allocation in the candidate allocation set to a second candidate allocation in the candidate allocation set. In some examples, a change in UE resource allocation can increase the allocation of UE resources (e.g., baseband resources, RF resources, and / or antennas, etc.) to cell groups with better channel conditions (e.g., MCG or SCG). For example, a change in UE resource allocation from a first candidate allocation to a second candidate allocation can increase the allocation of UE resources (e.g., baseband resources, RF resources, and / or antennas, etc.) to cell groups with better channel conditions (e.g., MCG or SCG) by reallocating UE resources previously allocated in the first candidate allocation to another cell group with poorer channel conditions.

[0197] In some aspects, indications of changes to UE resource allocation may be included in RRC messages (e.g., RRC reconfiguration messages). In other aspects, indications of changes to UE resource allocation may be sent via L2 signaling (e.g., in MAC-CE) or L1 signaling (e.g., in DCI). In some aspects, such as when indications of changes to UE resource allocation are sent via L1 or L2 signaling, UE 120 may use a set of parameters mapped to a candidate allocation corresponding to the new allocation when applying the new allocation of UE resources. For example, the new allocation may correspond to a change in the number of layers and / or antennas per CC in the cell group, and the set of parameters mapped to the candidate allocation corresponding to the new allocation may include parameters indicating the SRS resources to be monitored, CSI feedback, and / or DCI size and / or format. As a result of the mapping of the parameter set to the candidate allocation, UE 120 may update the parameters in conjunction with receiving the indication of changes to UE resource allocation without applying a full RRC reconfiguration, which reduces latency.

[0198] like Figure 9 As further illustrated by reference numeral 945, UE 120 can communicate with first network node 110-1 and second network node 110-2 via the first and second cell groups, respectively, based on a new allocation of UE resources (e.g., baseband resources, RF resources, and / or antennas, etc.) across the first and second cell groups. In some examples, UE 120 can apply the new allocation of UE resources across the first and second cell groups to send uplink communication to first network node 110-1 (e.g., MN) via the first cell group (e.g., MCG) and to second network node 110-2 (e.g., SN) via the second cell group. In some examples, first network node 110-1 can send downlink communication to UE 120 via the first cell group, and second network node 110-2 can send downlink communication to UE 120 via the second cell group. In such an example, UE 120 may apply a new allocation of UE resources across a first cell group and a second cell group to receive downlink communications transmitted via the first cell group (e.g., MCG) from a first network node 110-1 (e.g., MN) and via the second cell group (e.g., SCG) from a second network node 110-2 (e.g., SN).

[0199] As referenced above Figure 9As discussed, the MN and / or SN can exchange CSIs associated with the MCG and CSIs associated with the SCG, and the MN and / or SN can determine changes in UE resource allocation based at least in part on the CSIs associated with the MCG, the CSIs associated with the SCG, and capability information indicating resource allocation supported by UE 120. In some examples, changes in UE resource allocation can be determined to increase UE resources allocated to cell groups (e.g., MCG or SCG) with better channel conditions. Therefore, the MN and / or SN can manage dynamic sharing of UE resources by UE 120 based at least in part on the channel conditions (e.g., link quality) of UE 120 on the CCs of the MCG and SCG. This can enhance / increase downlink and uplink throughput of DC communication.

[0200] Despite the above reference Figure 9 The operations discussed are described in conjunction with DC, but the above references... Figure 9 The operations discussed can be similarly applied to the DS scenario. In the DS scenario, UE 120 can independently connect to two networks. For example, the two networks may be associated with the same or different operators. UE 120 may have two SIMs (e.g., two SIM cards), with each SIM used to connect to a different network. In the DS scenario, a first network node 110-1 may be associated with a first network, and a second network node 110-2 may be associated with a second network. UE 120 may connect to the first network via a first link with the first network node 110-1 and to the second network via a second link with the second network node 110-2. In such an example, UE 120 may send UE capability information associated with sharing UE resources across the first and second networks to the first network node 110-1 and / or the second network node 110-2, as referenced above. Figure 9 As described. In such examples, UE 120 may send the CSI of one network to a network node associated with another network. For example, UE 120 may send the CSI of the first network to a second network node 110-2, and / or UE 120 may send the CSI of the second network to a first network node 110-1.

[0201] As indicated above, Figure 9 This is provided as an example. Other examples are available with reference to [the relevant information]. Figure 9 The examples described are different.

[0202] Figure 10 This is a diagram illustrating an example 1000 associated with enhanced resource management for a DC with dynamically shared UE resources. (See diagram for example.) Figure 10As shown, UE 120 can communicate with first network node 110-1 and second network node 110-2. In some aspects, first network node 110-1, second network node 110-2, and UE 120 can be part of a wireless network (e.g., wireless network 100). Figure 10 Prior to the operations shown, UE 120 may have established radio connections with the first network node 110-1 and the second network node 110-2. In some aspects, for dual-connectivity communication with UE 120, the first network node 110-1 is the MN and the second network node 110-2 is the SN. In such examples, the first cell group associated with the first network node 110-1 may be an MCG and the second cell group associated with the second network node 110-2 may be an SCG. In some aspects, for dual-connectivity communication with UE 120, the second network node 110-2 is the MN and the first network node 110-1 is the SN. In such examples, the second cell group may be an MCG and the first cell group may be an SCG. In some aspects, the first network node 110-1 and the second network node 110-2 may be non-co-located.

[0203] In some aspects, such as in Figure 10 In Example 1000, UE 120 may transmit, and at least one of the first network node 110-1 or the second network node 110-2 may receive, second information associated with shared UE resources (e.g., baseband resources, RF resources, and / or antennas of UE 120) across the first and second cell groups. In such an example, UE 120 may communicate with the first network node 110-1 via the first cell group and with the second network node 110-2 via the second cell group, based at least in part on the allocation of UE resources across the first and second cell groups based on the second information. In Example 1000, the second information may include or be included therein an enhanced UAI. For example, the second information may include a UAI indicating a request to increase UE resources allocated to the first in the first or second cell group and / or a request to decrease UE resources allocated to the second in the first or second cell group. In some aspects, references Figure 10 The operations discussed can be performed without managing the splitting of data across the first and second cell groups, as referenced above. Figures 6 to 8 The discussion is ongoing. In some other respects, refer to... Figure 10 The operations discussed can be performed in conjunction with the management of data splitting across the first and second cell groups. For example, refer to... Figure 10 The operations discussed can be referenced. Figure 6 , Figure 7 or Figure 8 The combination of operations discussed.

[0204] like Figure 10 As shown by reference numeral 1005, UE 120 can send and first network node 110-1 can receive UE capability information. For example, the UE can send and first network node 110-1 can receive a capability report including UE capability information. Additionally or alternatively, second network node 110-2 can receive UE capability information. In some examples, second network node 110-2 can receive UE capability information from first network node 110-1 (e.g., first network node 110-1 can forward UE capability information to second network node 110-2). In some other examples, second network node 110-2 can receive UE capability information from UE 120 (e.g., as a supplement or alternative to first network node 110-1 receiving UE capability information).

[0205] UE capability information may indicate one or more capabilities associated with a DC. For example, UE capability information may indicate whether UE120 supports (e.g., is capable of) DC communication. In some aspects, UE capability information may indicate one or more frequency band combinations for a DC supported by UE 120. In some aspects, UE capability information may indicate UE 120's capabilities for feature sets and / or maximum power in FR1 and FR2.

[0206] In some aspects, UE capability information may include capability information associated with the ability of UE 120 to share UE resources (e.g., baseband resources, RF resources, and / or antennas, etc.) across a first cell group and a second cell group (e.g., sharing UE resources for communication via the first cell group and the second cell group). In some aspects, the capability information associated with the ability of UE 120 to share UE resources may include multiple shared capability profiles supported by UE 120. For example, each shared capability profile may correspond to a different sharing state (e.g., different allocations of UE resources for communication via different cell groups).

[0207] like Figure 10As further illustrated by reference numeral 1010, in some aspects, the first network node 110-1 and the second network node 110-2 may coordinate to determine the SCG configuration for UE 120. In some aspects, the MN (e.g., the first network node 110-1) and the SN (e.g., the second network node 110-2) may coordinate to determine the SCG configuration for UE 120 based at least in part on UE capability information. For example, the MN may supervise the resolution of dependencies between the MCG configuration and the SCG configuration of UE 120. The MN may determine the MCG configuration and a list of possible SCG configurations, and the MN may send the list of possible SCG configurations to the SN. The list of possible SCG configurations may include possible DC band combinations and / or feature sets based at least in part on UE capability information. In some examples, the SN may select an SCG configuration from the list of possible SCG configurations and report the selected SCG configuration to the MN. Alternatively, the SN may negotiate with the MN regarding the selection of the SCG configuration. For example, the SN can initiate modifications to the list of possible SCG configurations and indicate one or more desired SCG configurations (e.g., desired frequency band combinations and / or feature sets) outside the list of possible SCG configurations selected by the MN. The MN can then make the final determination of the SCG configuration.

[0208] like Figure 10 As further illustrated by reference numeral 1015, the first network node 110-1 can send and the UE 120 can receive configuration information. In some examples, the MN (e.g., the first network node 110-1) can send configuration information to the UE 120. In some examples, the UE 120 can receive configuration information from the SN or from both the MN and the SN. In some aspects, the UE 120 can receive configuration information via one or more RRC messages. Additionally or alternatively, the UE 120 can receive configuration information via system information (e.g., MIB and / or SIB, etc.), one or more MAC-CEs, and / or DCIs, etc.

[0209] In some aspects, the configuration information may indicate one or more candidate configuration and / or communication parameters. In some aspects, these one or more candidate configuration and / or communication parameters may be selected, activated, and / or deactivated by subsequent indications. For example, subsequent indications may select candidate configuration and / or communication parameters from the one or more candidate configuration and / or communication parameters. In some aspects, subsequent indications may include dynamic indications, such as one or more MAC-CE and / or one or more DCI messages, etc.

[0210] In some aspects, configuration information can be used to configure UE 120 for DC communication. For example, configuration information may include MCG and SCG configurations for UE 120. In some examples, configuration information may indicate the CC (or cell) in each cell group, the active BWP for the CC in each cell group, and / or the number of MIMO layers to be used for each cell group, etc.

[0211] In some aspects, configuration information may configure UE 120 to perform channel measurements and report channel measurements. For example, configuration information may include configurations for one or more CSI-RS to be measured by UE 120 and configurations for one or more CSI reports to be sent by UE 120. In some aspects, configuration information may configure UE 120 to measure one or more first CSI-RS associated with a first cell group (e.g., MCG) and to measure one or more second CSI-RS associated with a second cell group (e.g., SCG). In such examples, configuration information may configure UE 120 to report the first CSI associated with the first cell group (e.g., MCG) to a first network node 110-1 (e.g., MN) and to report the second CSI associated with the second cell group (e.g., SCG) to a second network node 110-2 (e.g., SN).

[0212] In some aspects, the configuration information may indicate a set of candidate allocations for UE resources. Each candidate allocation in the set may correspond to a corresponding possible allocation of UE resources (e.g., BB resources, RF resources, and / or antennas of UE 120) across MCG and SCG. The set of candidate allocations may be based, at least in part, on multiple shared capability profiles indicated in the UE capability information. For example, each candidate allocation in the set may correspond to a shared capability profile supported by UE 120. In some aspects, the configuration information may indicate a mapping between each candidate allocation in the set and a corresponding set of parameters to be used for that candidate allocation. For example, the corresponding set of parameters mapped to a candidate allocation may include parameters such as SRS resources, CSI feedback, and / or the size and / or format of the DCI to be monitored. In some aspects, the configuration information may indicate an initial or default allocation of UE resources selected from the set of candidate allocations.

[0213] like Figure 10As further illustrated by reference numeral 1020, UE 120 can perform channel measurements on the MCG and SCG. For example, a first network node 110-1 can transmit one or more first CSI-RSs via a first cell group (e.g., MCG), and UE 120 can perform channel measurements on one or more first CSI-RSs. UE 120 can determine or derive a first CSI based at least in part on the channel measurements performed on one or more first CSI-RSs. The first CSI may include one or more estimates and / or measurements of channel conditions (e.g., downlink channel conditions) on UE channels to the first cell group (e.g., MCG). UE 120 can perform channel measurements for each CC of the first cell group, and the first CSI may include a CSI for each CC of the first cell group. A second network node can transmit one or more second CSI-RSs via a second cell group (e.g., SCG), and UE 120 can perform channel measurements on one or more second CSI-RSs. UE 120 can determine or derive a second CSI based at least in part on the channel measurements performed on one or more second CSI-RSs. The second CSI may include one or more estimates and / or measurements of channel conditions (e.g., downlink channel conditions) on UE channels to the second cell group (e.g., SCG). UE120 may perform channel measurements for each CC of the second cell group, and the second CSI may include CSI for each CC of the second cell group.

[0214] In some aspects, the first UE 120 may transmit and the first network node 110-1 may receive a first CSI. For example, UE 120 may transmit a first CSI report including the first CSI to the first network node 110-1. In some aspects, the first UE 120 may transmit and the second network node 110-2 may receive a second CSI. For example, UE 120 may transmit a second CSI report including the second CSI to the second network node 110-2.

[0215] like Figure 10As further illustrated by reference numeral 1025, UE 120 can send, and at least one of the first network node 110-1 or the second network node 110-2 can receive, a UAI requesting a change in the allocation of UE resources across MCGs (e.g., the first cell group) and SCGs (e.g., the second cell group). UE 120 can access the channel conditions (e.g., the first CSI) between UE 120 and the MN on each of the CCs configured for the MCG, and the channel conditions (e.g., the second CSI) between UE 120 and the SN on each of the CCs configured for the SCG. In some aspects, UE 120 can determine its preference for how to allocate UE resources across the MCGs and SCGs based at least in part on the channel conditions associated with the MCGs and SCGs. UE 120 can send the UAI requesting a change in the allocation of UE resources based at least in part on its preference for how to allocate UE resources across the MCGs and SCGs. In some examples, the UAI may request changes to the allocation of UE resources to increase the allocation of UE resources (e.g., baseband resources, RF resources, and / or antennas, etc.) to cell groups (e.g., MCG or SCG) with better channel conditions.

[0216] The UAI (also known as the "Enhanced UAI") can be used not only for power-saving considerations but also for the dynamic sharing of UE resources across MCGs and SCGs (e.g., to increase the throughput of DC communications). Therefore, the UAI enables UE 120 to request both upgrades (e.g., increases of one or more parameters) and downgrades (e.g., decreases of one or more parameters) of the configured UE resources allocated for communications associated with a cell group. In some aspects, the UAI may indicate a request to increase (e.g., upgrade) UE resources allocated to the first of the MCGs (e.g., the first cell group) or SCGs (e.g., the second cell group). Additionally or alternatively, the UAI may indicate a request to decrease (e.g., downgrade) UE 120 resources allocated to the second of the MCGs (e.g., the first cell group) or SCGs (e.g., the second cell group). In some aspects, the UAI may indicate a joint request for increasing (e.g., upgrading) UE resources allocated to one of the MCGs or SCGs and decreasing (e.g., downgrading) UE resources allocated to the other of the MCGs or SCGs. In some aspects, UAI may include per-cell-group requests for upgrading and / or downgrading one or more UE resources allocated to a cell group (e.g., number of layers, number of Rx antennas, number of resource blocks (RBs) and / or processing time, etc.) for each of the MCG and SCG.

[0217] In some examples, UE 120 may send a UAI message, including the UAI, to the determining network node (e.g., MN) or to both MN and SN. In some aspects, to quickly adapt to the allocation of UE resources, UE 120 may send the UAI via L1 signaling (e.g., UCI) or L2 signaling (e.g., MAC-CE).

[0218] In some aspects, UE 120 may send, and at least one of the first network node 110-1 or the second network node 110-2 may receive, a dynamic capability update indicating an updated allocation of UE resources supported by UE 120. For example, UE 120 may send a dynamic capability update as an alternative to or supplement to UAI. In some examples, UE 120 may send a dynamic capability update to signal to network entities a new capability for a given CC (e.g., MCG or SCG). In such examples, the new capability may be considered (e.g., by the first network node 110-1 or the second network node 110-2) a preference of UE 120. In some aspects, UE 120 may send dynamic capability updates via L1 signaling (e.g., DCI), L2 signaling (e.g., MAC-CE), or L3 signaling (e.g., RRC messages).

[0219] like Figure 10 As further illustrated by reference numeral 1030, the first network node 110-1 can send, and the UE 120 can receive, an indication of the allocation of UE resources across the first and second cell groups. Additionally or alternatively, as shown by reference numeral 1030a, the second network node 110-2 can send, and the UE 120 can receive, an indication of the allocation of UE resources across the first and second cell groups. In some examples, the indication of UE resource allocation may be sent to the UE 120 via the first cell group (e.g., from the first network node 110-1), via the second cell group (e.g., from the second network node 110-2), or via both the first and second cell groups. In some aspects, the indication of UE resource allocation may be based at least in part on a UAI sent by the UE 120.

[0220] In some examples, the indication of UE resource allocation may indicate a change from a previous allocation of UE resources across a first cell group and a second cell group to a new allocation of UE resources across the first cell group and the second cell group. In some aspects, the indication of UE resource allocation may include an indication of a candidate allocation in a candidate allocation set indicated in the configuration information corresponding to the new allocation. For example, the indication of UE resource allocation may indicate a change from a first candidate allocation in the candidate allocation set to a second candidate allocation in the candidate allocation set.

[0221] In some aspects, indications for the allocation of UE resources may be sent via L1 signaling (e.g., in DCI) or L2 signaling (e.g., in MAC-CE) (e.g., at least in part based on UAI). In some aspects, UE 120 may use a set of parameters mapped to a candidate allocation set corresponding to the new allocation when applying a new allocation of UE resources.

[0222] In some respects, when UE 120 sends a dynamic capability update, the indication of UE resource allocation may be based at least in part on the dynamic capability update. In such examples where the indication of UE resource allocation is based on the dynamic capability update, the indication of UE resource allocation may be sent via L1 signaling (e.g., in DCI), L2 signaling (e.g., in MAC-CE), or L3 signaling (e.g., in RRC messages). When a request for updated allocation associated with a dynamic capability update is granted by the network (e.g., by the first network node 110-1 or the second network node 110-2), the indication of UE 120 resource allocation may be a change from a previous allocation of UE resources across the first and second cell groups to an updated allocation of UE resources across the first and second cell groups.

[0223] like Figure 10 As further illustrated by reference numeral 1035, UE 120 can communicate with first network node 110-1 and second network node 110-2 via the first and second cell groups, respectively, according to the indicated allocation of UE resources (e.g., baseband resources, RF resources, and / or antennas, etc.) across the first and second cell groups. In some examples, UE 120 can apply the indicated allocation of UE resources across the first and second cell groups (e.g., a new allocation of UE resources) to send uplink communication to first network node 110-1 (e.g., MN) via the first cell group (e.g., MCG) and to second network node 110-2 (e.g., SN) via the second cell group. In some examples, first network node 110-1 can send downlink communication to UE 120 via the first cell group, and second network node 110-2 can send downlink communication to UE 120 via the second cell group. In such an example, UE 120 may apply the indicated allocation of UE resources across the first cell group and the second cell group (e.g., a new allocation of UE resources) to receive downlink communications transmitted via the first cell group (e.g., MCG) from the first network node 110-1 (e.g., MN) and via the second cell group (e.g., SCG) from the second network node 110-2 (e.g., SN).

[0224] As referenced above Figure 10As discussed, UE 120 can send a UAI (or dynamic capability update) requesting a change in the allocation of UE resources, determined at least in part based on the CSI associated with the MCG and the CSI associated with the SCG. In some examples, the UAI may request a change in the allocation of UE resources to increase the allocation of UE resources to cell groups with better channel conditions (e.g., MCG or SCG). This allows the MN and / or SN to indicate changes in the allocation of UE resources, at least in part based on the UAI (or dynamic capability update). This can enhance / increase downlink and uplink throughput of DC communications.

[0225] Despite the above reference Figure 10 The operations discussed are described in conjunction with DC, but the above references... Figure 10 The operations discussed can be similarly applied to the DS scenario. In the DS scenario, UE 120 can independently connect to two networks. For example, the two networks may be associated with the same or different operators. UE 120 may have two SIMs (e.g., two SIM cards), with each SIM used to connect to a different network. In the DS scenario, a first network node 110-1 may be associated with a first network, and a second network node 110-2 may be associated with a second network. UE 120 may connect to the first network via a first link with the first network node 110-1 and to the second network via a second link with the second network node 110-2. In such an example, UE 120 may send a UAI to the first network node 110-1 and / or the second network node 110-2, indicating a preference or request to change the allocation of UE resources associated with the first network and / or the second network, as referenced above. Figure 10 As described.

[0226] As indicated above, Figure 10 This is provided as an example. Other examples are available with reference to [the relevant information]. Figure 10 The examples described are different.

[0227] Figure 11 This is a diagram illustrating example 1100 associated with enhanced resource management for a DC with dynamically shared UE resources. (See diagram for example.) Figure 11 As shown, UE 120 can communicate with first network node 110-1 and second network node 110-2. In some aspects, first network node 110-1, second network node 110-2, and UE 120 can be part of a wireless network (e.g., wireless network 100). Figure 11Prior to the operations shown, UE 120 may have established radio connections with the first network node 110-1 and the second network node 110-2. In some aspects, for dual-connectivity communication with UE 120, the first network node 110-1 is the MN and the second network node 110-2 is the SN. In such examples, the first cell group associated with the first network node 110-1 may be an MCG and the second cell group associated with the second network node 110-2 may be an SCG. In some aspects, for dual-connectivity communication with UE 120, the second network node 110-2 is the MN and the first network node 110-1 is the SN. In such examples, the second cell group may be an MCG and the first cell group may be an SCG. In some aspects, the first network node 110-1 and the second network node 110-2 may be non-co-located.

[0228] In some aspects, such as in Figure 11 In Example 1100, UE 120 may transmit, and at least one of the first network node 110-1 or the second network node 110-2 may receive, second information associated with shared UE resources (e.g., baseband resources, RF resources, and / or the antenna of UE 120) across the first and second cell groups. In such an example, UE 120 may communicate with the first network node 110-1 via the first cell group and with the second network node 110-2 via the second cell group, based at least in part on the allocation of UE resources across the first and second cell groups according to the second information. In Example 1100, the second information may indicate the allocation of UE resources to be used for DC communication across the first and second cell groups. For example, the second information may indicate the allocation of UE resources determined by UE 120. In some aspects, references Figure 11 The operations discussed can be performed without managing the splitting of data across the first and second cell groups, as referenced above. Figures 6 to 8 The discussion is ongoing. In some other respects, refer to... Figure 11 The operations discussed can be performed in conjunction with the management of data splitting across the first and second cell groups. For example, refer to... Figure 11 The operations discussed can be referenced. Figure 6 , Figure 7 or Figure 8 The combination of operations discussed.

[0229] like Figure 11As indicated by reference numeral 1105, UE 120 can send and first network node 110-1 can receive UE capability information. For example, the UE can send and first network node 110-1 can receive a capability report including UE capability information. Additionally or alternatively, second network node 110-2 can receive UE capability information. In some examples, second network node 110-2 can receive UE capability information from first network node 110-1 (e.g., first network node 110-1 can forward UE capability information to second network node 110-2). In some other examples, second network node 110-2 can receive UE capability information from UE 120 (e.g., as a supplement or alternative to first network node 110-1 receiving UE capability information).

[0230] UE capability information may indicate one or more capabilities associated with a DC. For example, UE capability information may indicate whether UE120 supports (e.g., is capable of) DC communication. In some aspects, UE capability information may indicate one or more frequency band combinations for a DC supported by UE 120. In some aspects, UE capability information may indicate UE 120's capabilities for feature sets and / or maximum power in FR1 and FR2.

[0231] In some aspects, UE capability information may include capability information associated with the ability of UE 120 to share UE resources (e.g., baseband resources, RF resources, and / or antennas, etc.) across a first cell group and a second cell group (e.g., sharing UE resources for communication via the first cell group and the second cell group). In some aspects, the capability information associated with the ability of UE 120 to share UE resources may include multiple shared capability profiles supported by UE 120. For example, each shared capability profile may correspond to a different sharing state (e.g., different allocations of UE resources for communication via different cell groups).

[0232] like Figure 11As further illustrated by reference numeral 1110, in some aspects, the first network node 110-1 and the second network node 110-2 may coordinate to determine the SCG configuration for UE 120. In some aspects, the MN (e.g., the first network node 110-1) and the SN (e.g., the second network node 110-2) may coordinate to determine the SCG configuration for UE 120 based at least in part on UE capability information. For example, the MN may supervise the resolution of dependencies between the MCG configuration and the SCG configuration of UE 120. The MN may determine the MCG configuration and a list of possible SCG configurations, and the MN may send the list of possible SCG configurations to the SN. The list of possible SCG configurations may include possible DC band combinations and / or feature sets based at least in part on UE capability information. In some examples, the SN may select an SCG configuration from the list of possible SCG configurations and report the selected SCG configuration to the MN. Alternatively, the SN may negotiate with the MN regarding the selection of the SCG configuration. For example, the SN can initiate modifications to the list of possible SCG configurations and indicate one or more desired SCG configurations (e.g., desired frequency band combinations and / or feature sets) outside the list of possible SCG configurations selected by the MN. The MN can then make the final determination of the SCG configuration.

[0233] like Figure 11 As further illustrated by reference numeral 1115, the first network node 110-1 can send and the UE 120 can receive configuration information. In some examples, the MN (e.g., the first network node 110-1) can send configuration information to the UE 120. In some examples, the UE 120 can receive configuration information from the SN or from both the MN and the SN. In some aspects, the UE 120 can receive configuration information via one or more RRC messages. Additionally or alternatively, the UE 120 can receive configuration information via system information (e.g., MIB and / or SIB, etc.), one or more MAC-CEs, and / or DCIs, etc.

[0234] In some aspects, the configuration information may indicate one or more candidate configuration and / or communication parameters. In some aspects, these one or more candidate configuration and / or communication parameters may be selected, activated, and / or deactivated by subsequent indications. For example, subsequent indications may select candidate configuration and / or communication parameters from the one or more candidate configuration and / or communication parameters. In some aspects, subsequent indications may include dynamic indications, such as one or more MAC-CE and / or one or more DCI messages, etc.

[0235] In some aspects, configuration information can be used to configure UE 120 for DC communication. For example, configuration information may include MCG and SCG configurations for UE 120. In some examples, configuration information may indicate the CC (or cell) in each cell group, the active BWP for the CC in each cell group, and / or the number of MIMO layers to be used for each cell group, etc.

[0236] In some aspects, configuration information may configure UE 120 to perform channel measurements and report channel measurements. For example, configuration information may include configurations for one or more CSI-RS to be measured by UE 120 and configurations for one or more CSI reports to be sent by UE 120. In some aspects, configuration information may configure UE 120 to measure one or more first CSI-RS associated with a first cell group (e.g., MCG) and to measure one or more second CSI-RS associated with a second cell group (e.g., SCG). In such examples, configuration information may configure UE 120 to report the first CSI associated with the first cell group (e.g., MCG) to a first network node 110-1 (e.g., MN) and to report the second CSI associated with the second cell group (e.g., SCG) to a second network node 110-2 (e.g., SN).

[0237] In some aspects, the configuration information may indicate a set of candidate allocations for UE resources. Each candidate allocation in the set may correspond to a corresponding possible allocation of UE resources (e.g., BB resources, RF resources, and / or antennas of UE 120) across MCG and SCG. The set of candidate allocations may be based, at least in part, on multiple shared capability profiles indicated in the UE capability information. For example, each candidate allocation in the set may correspond to a shared capability profile supported by UE 120. In some aspects, the configuration information may indicate a mapping between each candidate allocation in the set and a corresponding set of parameters to be used for that candidate allocation. For example, the corresponding set of parameters mapped to a candidate allocation may include parameters such as SRS resources, CSI feedback, and / or the size and / or format of the DCI to be monitored. In some aspects, the configuration information may indicate an initial or default allocation of UE resources selected from the set of candidate allocations.

[0238] In some aspects, the configuration information may include configuration information associated with the selection of UE resource allocation across a first cell group (e.g., MCG) and a second cell group (e.g., SCG). That is, the configuration information may configure UE 120 to select UE resource (e.g., baseband resources, RF resources, and / or antennas, etc.) allocation across MCG and SCG. For example, the configuration information may configure one or more parameters and / or conditions to facilitate UE 120's selection of UE resource allocation and / or constrain the solution (e.g., the selected allocation of UE resources) within the boundaries of the control network. In some examples, the configuration information associated with the selection split may define (or indicate) the metrics and / or algorithms used by UE 120 to select UE resource allocation, one or more inputs to the algorithm (e.g., how to derive the channel estimate to be used, which reference signals to use to derive the channel estimate, how to perform TD and / or FD filtering of the channel estimate and / or which ranks, number of layers, and / or MCS, etc., to be considered), and / or one or more relevant thresholds to trigger changes in UE resource allocation, etc. In some aspects, configuration information associated with the allocation of selected UE resources may be determined by MN, SN, or both MN and SN (e.g., involving negotiation and / or handshake), and the configuration information associated with the allocation of selected UE resources may be sent to UE 120 by MN, SN, or both MN and SN. For example, configuration information associated with the selection split may be signaled via L3 signaling (e.g., one or more RRC messages), L2 signaling (e.g., one or more MAC-CEs), and / or L1 signaling (e.g., DCI).

[0239] like Figure 11As further illustrated by reference numeral 1120, UE 120 can perform channel measurements on the MCG and SCG. For example, the first network node 110-1 can transmit one or more first CSI-RSs via the first cell group (e.g., MCG), and UE 120 can perform channel measurements on one or more first CSI-RSs. UE 120 can determine or derive the first CSI based at least in part on the channel measurements performed on one or more first CSI-RSs. The first CSI can include one or more channel estimates and / or measurements of channel conditions (e.g., downlink channel conditions) on UE channels to the first cell group (e.g., MCG). For example, the first CSI can include one or more channel estimates indicated in the configuration information, which will be used by UE 120 to select the allocation of UE resources across the first and second cell groups. UE 120 can perform channel measurements for each CC of the first cell group, and the first CSI can include a CSI for each CC of the first cell group. The second network node may transmit one or more second CSI-RSs via a second cell group (e.g., SCG), and the UE 120 may perform channel measurements on the one or more second CSI-RSs. The UE 120 may determine or derive the second CSI based at least in part on the channel measurements performed on the one or more second CSI-RSs. The second CSI may include one or more channel estimates and / or measurements of channel conditions (e.g., downlink channel conditions) on UE channels to the second cell group (e.g., SCG). For example, the second CSI may include one or more channel estimates indicated in the configuration information, which will be used by the UE 120 to select the allocation of UE resources across the first and second cell groups. The UE 120 may perform channel measurements for each CC of the second cell group, and the second CSI may include a CSI for each CC of the second cell group.

[0240] In some aspects, the first UE 120 may transmit and the first network node 110-1 may receive a first CSI. For example, UE 120 may transmit a first CSI report including the first CSI to the first network node 110-1. In some aspects, the first UE 120 may transmit and the second network node 110-2 may receive a second CSI. For example, UE 120 may transmit a second CSI report including the second CSI to the second network node 110-2.

[0241] like Figure 11As further illustrated by reference numeral 1125, UE 120 can select the allocation of UE resources across MCG and SCG. In some aspects, UE 120 can select the allocation of UE resources to be used for uplink and / or downlink communication across a first cell group (e.g., MCG) and a second cell group (e.g., SCG). For example, UE 120 can select the allocation of UE resources to be applied to UE resources shared across a first cell group (e.g., MCG) and a second cell group (e.g., SCG). In some examples, UE 120 can select the allocation of UE resources to favor allocating UE resources to cell groups (e.g., MCG or SCG) with better channel conditions. In some aspects, UE 120 can determine the allocation of UE resources based at least in part on channel estimates associated with the first cell group (e.g., MCG) and channel estimates associated with the second cell group (e.g., SCG). For example, the channel estimate associated with the first cell group may be included in a first CSI, and the channel estimate associated with the second cell group may be included in a second CSI. In some examples, channel estimations associated with MCG and SCG may be defined or indicated in configuration information (e.g., splitting thresholds) associated with the selection of UE resource allocation. In some aspects, UE 120 may use metrics or algorithms defined in the configuration information to select / determine the allocation of UE resources. In some aspects, UE 120 may be triggered to select UE resource allocation (e.g., a new allocation of UE resources) by combining the satisfaction of triggering conditions for changing the allocation of UE resources. For example, triggering conditions for changing the allocation of UE resources may be defined in the configuration information associated with the selection of UE resource allocation.

[0242] In some respects, the selection of UE resource allocation across the first and second cell groups may be subject to one or more restrictions. In this case, one or more restrictions may be (e.g., based on) the UE capabilities indicated in the UE capability information and / or the network configuration indicated in the configuration information. For example, UE 120 may be restricted to not allocating all of UE 120's transmit (Tx) and Rx antennas to the SCG, and / or UE 120 may be required to support at least a single layer of Tx / Rx when sharing UE resources between the MCG and SCG, and so on.

[0243] In some respects, UE 120 may select an allocation of UE resources across a first cell group and a second cell group from a set of candidate allocations indicated in the configuration information. In such an example, when UE 120 begins to apply the selected allocation, UE 120 may also begin to apply the set of parameters mapped to the selected allocation in the configuration information.

[0244] In some aspects, UE 120 may select a time pattern for sharing UE resources. For example, the allocation of UE resources selected by UE 120 may include a time pattern for switching between different allocations of UE resources across a first cell group and a second cell group. In such examples, UE 120's selection of a time pattern may be subject to one or more limitations on the extent to which UE resources are borrowed / shared across MCGs and SCGs, at least in part, based on various factors, including the TDD mode of the CC in the MSG and SCG, network configuration (e.g., indicated in the configuration information), and / or UE capabilities (e.g., indicated in the UE capability information), etc.

[0245] like Figure 11 As further illustrated by reference numeral 1130, UE 120 can send, and at least one of the first network node 110-1 or the second network node 110-2 can receive, an indication of the allocation of UE resources selected by UE 120. For example, the indication of UE resource allocation can indicate the allocation of UE resources (e.g., baseband resources, RF resources, and / or antennas, etc.) to be applied to uplink and downlink communications across a first cell group (e.g., MCG) and a second cell group (e.g., SCG). In some aspects, UE 120 can send the indication of UE resource allocation via L3 signaling (e.g., RRC message), L2 signaling (e.g., MAC-CE), or L1 signaling (e.g., UCI). In some aspects, UE 120 can send the indication of UE resource allocation to MN, SN, or both MN and SN.

[0246] like Figure 11 As further illustrated by reference numeral 1135, the first network node 110-1 can send, and the UE 120 can receive, an acknowledgment of an instruction for the allocation of UE resources. Additionally or alternatively, as shown by reference numeral 1135a, the second network node 110-2 can send, and the UE 120 can receive, an acknowledgment of an instruction for the allocation of UE resources. In some aspects, the UE 120 can apply the allocation of UE resources selected by the UE 120 (e.g., for uplink communication and / or downlink communication) in conjunction with the received acknowledgment. In some aspects, when the selected allocation of UE resources is a candidate allocation in a set of candidate allocations indicated in the configuration information, the UE 120 can also begin applying a set of parameters mapped to the selected candidate allocation in the configuration information.

[0247] In some respects, UE 120 may perform a soft-level handshake with the first network node 110-1 and / or the second network node 110-2. For example, UE 120 may send an indication of UE resource allocation to the first of the MN or SN (e.g., in conjunction with a determination that more UE resources are being allocated to the first of the MN or SN than to the second of the MN or SN). Once the first of the MN or SN approves the indication of UE resource allocation (e.g., UE 120 receives confirmation of the indication from the first of the MN or SN), UE 120 may send the indication of UE resource allocation determined by UE 120 to the second of the MN or SN, or to both the MN and SN.

[0248] like Figure 11 As further illustrated by reference numeral 1140, UE 120 can communicate with first network node 110-1 and second network node 110-2 via the first cell group and the second cell group, respectively, based on a selected allocation of UE resources (e.g., baseband resources, RF resources, and / or antennas, etc.) across the first cell group and the second cell group. In some examples, UE 120 can apply a selected allocation of UE resources across the first cell group and the second cell group (e.g., a new allocation of UE resources) to send uplink communication to first network node 110-1 (e.g., MN) via the first cell group (e.g., MCG) and to second network node 110-2 (e.g., SN) via the second cell group. In some examples, first network node 110-1 can send downlink communication to UE 120 via the first cell group and second network node 110-2 can send downlink communication to UE 120 via the second cell group. In such an example, UE 120 may apply a selected allocation of UE resources across a first cell group and a second cell group (e.g., a new allocation of UE resources) to receive downlink communications transmitted via the first cell group (e.g., MCG) from a first network node 110-1 (e.g., MN) and via the second cell group (e.g., SCG) from a second network node 110-2 (e.g., SN).

[0249] As referenced above Figure 11As discussed, UE 120 can select the allocation of UE resources across MCG and SCG for DC communication based at least in part on the channel conditions (e.g., first CSI and second CSI) of UE 120 on the CC of MCG and SCG. In some examples, the allocation of UE resources can be selected to favor the allocation of UE resources to cell groups (e.g., MCG or SCG) with better channel conditions. UE 120 can send an indication of the selected allocation of UE resources to MN and / or SN. This can enhance / increase the downlink and uplink throughput of DC communication. Furthermore, because the determination of the allocation of UE resources across MCG and SCG does not involve significant coordination between MN and SN, it is consistent with the above references. Figure 9 and Figure 10 Compared to the operations discussed, this reduces latency and can further increase throughput.

[0250] Despite the above reference Figure 11 The operations discussed are described in conjunction with DC, but the above references... Figure 11 The operations discussed can be similarly applied to the DS scenario. In the DS scenario, UE 120 can independently connect to two networks. For example, the two networks may be associated with the same or different operators. UE 120 may have two SIMs (e.g., two SIM cards), with each SIM used to connect to a different network. In the DS scenario, a first network node 110-1 may be associated with a first network, and a second network node 110-2 may be associated with a second network. UE 120 may connect to the first network via a first link with the first network node 110-1 and to the second network via a second link with the second network node 110-2. In such an example, UE 120 may select the allocation of UE resources across the first and second networks, and UE 120 may send instructions to the first network node 110-1 and / or the second network node 110-2 regarding the selected allocation of UE resources across the first and second networks, as referenced above. Figure 11 As described.

[0251] As indicated above, Figure 11 This is provided as an example. Other examples are available with reference to [the relevant information]. Figure 11 The examples described are different.

[0252] In some examples where a UE (e.g., UE 120) can share UE resources across MCG and SCG, such as in Examples 1100, 1000, and 900 discussed above, resource sharing may prevent the UE from performing the correct measurements needed to determine when to update UE resource allocation. For example, in the extreme case where the UE has moved all of its Rx antennas to the SCG, the UE will be unable to receive from the MN (e.g., via the MCG) at all. In cases where the UE has moved most of its Rx antennas to the SCG, the UE may be unable to assess whether support is possible on the MCG. X layer( X >1) Transmission. In some aspects, gaps similar to measurement gaps used for Radio Resource Management (RRM) can be configured for UE use across MCGs and SCGs when the remaining UE resources allocated to a cell group (e.g., MCG or SCG) are insufficient to update decisions. In such examples, the gaps, and the configurations on the MCG and SCG during the gap time, can be determined by the network and / or selected by the UE. In some other aspects, the permissible sharing level of UE resources can be limited such that, in the worst case, the remaining resources allocated to a cell group (e.g., MCG or SCG) are sufficient to reassess the choice of UE resource allocation if needed. For example, UE resource sharing might be limited by the restriction that all of the UE's antennas except for the two RX antennas can be shared across MCGs and SCGs. In this case, the network and UE can understand that measurement configuration and calculations should be based on the assumption of two Rx antennas. In some examples, resource sharing / borrowing at each level can be a priori associated with the measurement configuration set without requiring reconfiguration. In this case, once the UE is given a sharing state corresponding to the allocation of UE resources, both the network and the UE will know how to perform and report measurements.

[0253] In some respects, in addition to the examples discussed above, refer to Figures 6 to 11 The operations discussed can be similarly applied to other operating modes when a UE connects to a non-coordinated or loosely coordinated scheduler and / or network entity, such as multi-RAT (mRAT) DC, dual-stack (e.g., when a UE connects to 6G RAN, 5G RAN and 6G core network, with connectivity between 5G RAN and 6G core network), sidelink + Uu connection, sidelink + sidelink connection and / or WiFi + cellular connection, etc.
