[0001] Cross-reference to related applications

[0002] This patent application claims priority to U.S. Provisional Patent Application No. 63 / 598,065, filed November 10, 2023, entitled “STABLE POWER HEADROOMREFERENCE FOR CARRIER AGGREGATION,” and U.S. Non-Provisional Patent Application No. 18 / 883,983, filed September 12, 2024, entitled “STABLE POWER HEADROOMREFERENCE FOR CARRIER AGGREGATION,” which are hereby expressly incorporated herein by reference. Background Technology

[0003] All aspects of this disclosure relate to wireless communication in general, and specifically to techniques, apparatus and methods associated with power headroom reference values.

[0004] 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.

[0005] 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] Carrier aggregation (CA) is a technique that enables two or more component carriers (CCs, sometimes referred to as carriers) to be combined (e.g., combined into a single channel) for a single user equipment (UE) to enhance data capacity. Carriers in the same or different frequency bands can be combined. Additionally or alternatively, contiguous or discontinuous carriers can be combined. Network nodes can configure carrier aggregation for the UE in messages such as Radio Resource Control (RRC) messages, Downlink Control Information (DCI) messages, and / or other signaling messages.

[0032] In some aspects, carrier aggregation can be configured in an intra-band continuous mode, where the aggregated carriers are consecutive and in the same frequency band. In some aspects, carrier aggregation can be configured in an intra-band discontinuous mode, where the aggregated carriers are discontinuous and in the same frequency band. In some aspects, carrier aggregation can be configured in an inter-band discontinuous mode, where the aggregated carriers are discontinuous and in different frequency bands.

[0033] In carrier aggregation, a UE can be configured with 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 other 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.

[0034] In some cases, the UE may determine a transmit power (e.g., one or more transmit powers) and may transmit at least one communication. For example, the UE may use the determined transmit power to transmit at least one communication. In some cases, for example, the UE may be configured with a CA configuration indicating a first component carrier (CC) and a second CC. The first CC may be associated with a first frequency band, and the second CC may be associated with a second frequency band. The UE may be configured to determine whether configuration information and / or scheduling information received from a network node indicates that parallel transmissions will exist during a transmission timing. For example, parallel transmissions may be two or more transmissions configured and / or scheduled to be transmitted within the same transmission timing and at least partially overlapping in the time domain. Transmission timings may include a set of time resources and / or frequency resources allocated, reserved, or otherwise used for a certain type of transmission. For example, transmission timings may include a RACH timing for transmitting a random access channel (RACH) message, a paging timing for transmitting a paging timing (PO), or another type of transmission timing. Non-parallel transmissions may be two or more transmissions that do not overlap at least partially in the time domain.

[0035] In some cases, a UE can be configured to transmit one or more uplink communications. The UE can use transmit power to transmit uplink communications, which can be determined by the UE and / or configured by the network node. The transmit power may be limited by a maximum transmit power limit (sometimes referred to as "maximum transmit power"), which refers to the maximum allowed transmit power (e.g., as defined in the wireless communication standard) and the configured maximum output power P. CMAX Used for carrier waves f The maximum output power P of the configuration CMAX,f Used in residential communities c The maximum output power P of the configuration (e.g., serving cell) CMAX,c Used in residential communities c The maximum output power P of the carrier f configuration CMAX,f,c The maximum transmit power, and / or the maximum transmit power determined at least in part based on the maximum power reduction, etc.

[0036] The maximum transmit power limit can be determined based on the per-band UE power level, which is a specified maximum UE transmit power associated with a frequency band (e.g., CC). In scenarios involving CA, the maximum transmit power limit can be determined based on the per-band UE power level and / or the power level of the CA, which is a specified maximum value of the sum of UE transmit powers associated with configured CCs. In some cases, the maximum transmit power can also be determined based on the per-band and per-band combined UE power levels, which is a specified maximum UE transmit power per frequency band associated with a combination of frequency bands (e.g., a combination of CCs in a CA).

[0037] In some cases, transmit power may also be limited by a Power Clearance Report (PHR) value (which may be referred to as a "power clearance value" or "power clearance"). Power clearance indicates the amount of remaining transmit power available to the UE beyond the power currently being used for transmission. Power clearance may be based at least in part on the difference between the UE's maximum transmit power and the transmit power. A PHR can be a Type 1 report for the Physical Uplink Shared Channel (PUSCH), a Type 3 report for the Sounding Reference Signal (SRS), and / or a Type 2 report for the Physical Uplink Control Channel (PUCCH), etc. For example, the type of UE PHR may include that for the serving cell... CC Active uplink (UL) bandwidth portion (BWP) PUSCH sending timing Valid Type 1 UE power headroom, or for the serving cell CC UL BWP activities SRS transmission timing Valid Type 3 UE power headroom. Therefore, PHR can be determined for CC and / or serving cell.

[0038] The UE can determine whether the PHR for the active serving cell is at least partially based on actual transmissions. Actual transmissions can be determined at least partially based on higher-layer signaling transmitted with configured permission and periodic / semi-persistent probe reference signals, and / or downlink control information (DCI) received by the UE. The UE can also determine whether the PHR for the active serving cell is at least partially based on a reference format. This reference format can be determined at least partially based on higher-layer signaling transmitted with configured permission and periodic / semi-persistent probe reference signals, or the DCI received by the UE. In some cases, the PHR value can then be calculated as a maximum transmit power limit (e.g., P...). CMAX The difference between the transmit power that would have been used without power constraints (e.g., the unconstrained transmit power for a single signal, or the sum of the unconstrained transmit power for multiple signals, such as higher priority signals).

[0039] For example, in some cases, the UE may periodically measure its available power headroom and report it to the network node. This report may be initiated by the network node via a specific signaling message and / or triggered based on one or more Power Headroom Reduction (PHR) triggers. The network node may configure PHR parameters for the UE, including reporting periodicity and measurement rules. Reporting periodicity determines the frequency at which the UE transmits the PHR, while the measurement rules define how the UE calculates its power headroom. For example, as indicated above, the UE may calculate the power headroom by considering factors such as the maximum transmit power defined by the network, the current transmit power, and / or any power limitations due to neighboring cells and / or interference. This calculation produces a PHR that provides a representation of the power available for the UE to transmit. In some cases, the UE may transmit the PHR to the network node via the uplink channel. The PHR may include a power headroom value and any additional information specified by the PHR configuration. Upon receiving the PHR from the UE, the network node may use the reported information to make decisions regarding resource allocation and / or power control. For example, network nodes can use information from the PHR to adjust the allocated resources and / or power levels for each UE to help maintain optimal system performance and avoid interference issues.

[0040] In the case of CA, if transmission timing is scheduled using parallel transmission, the UE can determine the first maximum transmit power limit P associated with the first CC based on the power class of CA (shown as "powerClass"). CMAX 1, and based on the power level of CA, determine the second maximum transmit power limit P associated with the second CC. CMAX 2. A first PHR reference value (shown as "PHR limit") associated with the first CC can be determined based on a first maximum transmit power limit, and a second PHR reference value associated with the second CC can be determined based on a second maximum transmit power limit. For example, in some cases, since the corresponding maximum transmit power limit can be determined based on the power level of the CA, the corresponding PHR limit can be based on the corresponding maximum transmit power limit and / or the power level of the CA. A PHR reference value refers to a PHR value that can be used as a reference. For example, in some cases, a PHR reference value can indicate the amount of power available (and / or potentially available) to the UE. In some cases, a PHR reference value can be a PHR 0 dB limit, which can indicate the maximum transmit power of the UE in the CA scenario and / or the maximum amount of power available to the UE in the CA scenario.

[0041] If parallel transmission is used to schedule transmission timing, the UE can determine the first maximum transmit power limit P associated with the first CC based on the power class of the CA (shown as "powerClass"). CMAX1. The UE can determine the second maximum transmit power limit P associated with the second CC based on the power level of the CA. CMAX 2. In conjunction with determining a first maximum transmit power limit (e.g., during operations for determining the first maximum transmit power limit), the UE can determine a first PHR reference value associated with the first CC. Similarly, in conjunction with determining a second maximum transmit power limit P... CMAX 2. The UE can determine a second PHR reference. In some cases, the corresponding PHR limit (for each CC) can be based on the corresponding maximum transmit power limit and / or the power level of the CA. The UE can base it on P... CMAX 1 and PHR limit 1 determine the first transmit power, and / or based on P CMAX 2 and PHR limit 2 are used to determine the second transmit power.

[0042] According to one example, if transmission timing is scheduled using only one communication and / or two or more non-parallel communications, the UE may determine a first maximum transmit power limit Pcmax1 based on a first per-band UE power class (e.g., "UE PBPowerClass 1") and a first per-band and per-band combination UE power class (e.g., "UE PBPBCPowerClass 1", such as, for example, "first ue-PowerClassPerBandPerBC-17"). The per-band power class is a power class applied to a specific frequency band (CC) (e.g., a specified maximum transmit power limit). The per-band and per-band combination power class is a power class applied to a specific frequency band (CC) within a combination of frequency bands (CC) (e.g., a specified maximum transmit power limit). Similarly, the UE may determine a second maximum transmit power limit Pcmax2 based on a second per-band UE power class (shown as "UE PBPowerClass 2") and a per-band and per-band combination UE power class (shown as "UE PBPBCPowerClass 2"). The UE may determine PHR Limit 1 based on the first per-band UE power class and the first per-band and per-band combined UE power class. Similarly, as part of the operation (e.g., in conjunction with determining Pcmax 2), the UE may determine a second PHR reference value associated with the second CC (shown as "PHR Limit 2"). In some cases, for example, PHR Limit 2 may be determined based on the second per-band UE power class (shown as "Second ue-PowerClass") and the second per-band and per-band combined UE power class (shown as "Second ue-PowerClassPerBandPerBC-17").

[0043] In some cases, to facilitate scheduling by network nodes and / or appropriate resource allocation for reception at network nodes, the UE may declare a power level (e.g., via UE capability information and / or PHR reporting) with one or more capabilities. UE capability information may include information provided by the UE indicating one or more capabilities of the UE to support one or more features. For example, UE capability information may indicate a power level supported by the UE, UE support for CA, and / or UE support for a certain type of PHR calculation, etc. One or more capabilities may include, for example, per-band UE power level, per-band and per-band combined UE power level and / or CA power level, etc. In some cases, when different power levels are declared between two bands in CA, UE 402 may use a higher-limited per-band and per-band combined power level to indicate a larger combined power limit.

[0044] For example, in some cases, the UE may declare a power level for PC2 associated with the first CC, a power level for PC3 associated with the second CC, and a power level for PC3 associated with the CA. In some cases, even if CC1 (e.g., the first frequency band) and CC2 (e.g., the second frequency band) have the same output power capability in both cases, the UE may choose to declare either PC3 or PC2 in the CA. In one or more examples, the UE may use per-band and per-band combined UE power levels to specify the maximum power associated with each frequency band.

[0045] As described above, wireless communication standards can specify a CA power level. However, in some cases, the timing of when a CA power level is applied by the wireless communication standard may be ambiguous. Because the CA power level can limit transmit power, resolving this ambiguity can lead to more efficient and / or effective communication. Furthermore, in some cases, the UE may declare a first power level associated with a CC, but ultimately use a second power level for the CC (e.g., as a result of using the power level for the CA instead). For example, the CA power level may be used in: 1) when both CCs are configured, 2) when both CCs are active, or 3) when both CCs are scheduled. In some cases, the wireless communication standard may specify that the CA power level will be used in: 1) when both CCs are configured. However, in some cases, although two CCs can be configured, the network node may allocate resources (e.g., schedule) for communication on only one CC or the other for a given transmission timing. Therefore, in some cases, option 3 (where the CA power level is used when both CCs are scheduled) may be the most efficient of the three options because if only one band is permitted to transmit, power limitation is not required.

[0046] In some cases, if option 3 is used, the PHR reference value of a CC can change based on transmissions on another CC. When the PHR reference value of a CC depends on another CC, from the network node's perspective, transmissions on another CC exceeding the power level associated with the CA can cause confusion. This confusion can occur because, for example, when only one CC is observed (e.g., by the Transmit Receive Point (TRP) associated with that one CC), the PHR may appear to change sporadically. In other words, the PHR in one CC appears unstable because the network node lacks information indicating transmission power changes in another CC from which its PHR is derived. If the network node is provided with more accurate information associated with the UE power level (e.g., the power level the UE will actually use) and stable PHRs (e.g., PHRs that appear unchanged in one CC due to transmissions in another CC), the network node can be able to allocate resources more efficiently and / or effectively for actual transmissions.

[0047] Some aspects of the techniques described herein can facilitate providing a stable PHR reference value for carrier aggregation. A stable PHR reference value is one that does not change based on changes in resource allocation type (e.g., a stable PHR reference value is the same for a single CC transmission as it is for overlapping CA transmissions on multiple CCs and / or non-overlapping CA transmissions on multiple CCs). For example, some aspects may include separating the calculation of the PHR reference value from the calculation of the maximum transmit power. In some aspects, separating the calculation of the PHR reference value from the calculation of the maximum transmit power allows the PHR reference value to be determined without considering the power level of the CA. This separation results in a stable PHR reference value for the CC (e.g., having the same value) regardless of whether the power level of the CA is being used to determine the maximum transmit power. Therefore, some aspects can enhance the predictability of transmit power, as transmit power is limited by the PHR reference value. In some aspects, the UE can determine the PHR reference value based on the per-band UE power level and the per-band and per-band combined UE power levels. For example, the UE can determine the PHR reference value as the maximum of the two power levels associated with the CC. In some cases, the PHR reference value for a CC can be determined based on the UE power level per frequency band and the combined UE power levels per frequency band and per frequency band, regardless of whether the network node schedules overlapping or non-overlapping transmissions for transmission timing. This can contribute to providing stable PHR reference values, thereby improving the predictability of UE transmit power determination for two or more CCs in a CA configuration. This leads to more efficient resource scheduling and more effective reception of UE transmits at the network, which can positively impact network and / or device performance.

[0052] 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 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 UE 120a, UE 120b, UE 120c, UE 120d, and UE 120e).

[0053] 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 radio access technology (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 RAT, 5G / NR RAT, and / or 6G RAT, 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.

[0054] 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.

[0055] 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).

[0056] 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.

[0057] 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 geographic 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 compliant with the O-RAN Alliance), 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.

[0058] Network nodes 110 of the 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 Radio Resource Control (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, Media Access Control (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 type of architecture, each RU can be operated to handle over-the-air (OTA) communications with one or more UE 120s.

[0059] 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.

[0060] Some network nodes 110 (e.g., base stations, RUs, or TRPs) can provide communication coverage for specific geographic areas. 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)). A network node 110 used for a macro cell may be referred to as a macro network node. Network node 110 used for a pico cell 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 be mobile based on the location of the associated mobile network node 110 (e.g., a train, satellite base station, unmanned aerial vehicle, or non-terrestrial network (NTN) network node).

[0061] 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. Compared to other types of network nodes 110, the various types of network nodes 110 typically transmit at different power levels, serve different coverage areas, and / or have different effects on interference in the wireless communication network 100. For example, macro network nodes may have high transmit power levels (e.g., 5 watts to 40 watts), while pico network nodes, femto network nodes, and relay network nodes may have lower transmit power levels (e.g., 0.1 watts to 2 watts).

[0062] In some examples, network node 110 may be, may include, or 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. A "downlink" (or "DL") refers to the communication direction from network node 110 to UE 120, and an "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.

[0063] 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.

[0064] 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.

[0065] 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 one or more examples, 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.

[0066] 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, an access terminal, another terminal, a mobile station, or a subscriber unit, or may be included in an access terminal, another terminal, a mobile station, or a 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 extended reality (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.

[0067] 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”). Processors may also be implemented as a combination of computing devices, such as a combination of a DSP and a microprocessor, multiple microprocessors, a combination of one or more microprocessors with a DSP core, or any other such configuration. One or more of these processors may be individually or collectively configurable 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.

[0068] 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 be included or may be contained in a housing that houses components associated with UE 120, including the processing system.

[0069] 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 collectively referred to as "MTC UEs". An MTC UE 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).

[0070] 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 lower cost compared to UEs 120 in the second category. UEs 120 in the second category may include mission-critical IoT devices, legacy UEs, baseline UEs, high-level UEs, advanced UEs, full-capability UEs, and / or premium UEs capable of ultra-reliable low-latency communication (URLLC), enhanced mobile broadband (eMBB), and / or precise positioning, etc., within the wireless communication network 100. UEs 120 in the third category may have intermediate-level complexity and / or capabilities (e.g., capabilities between UEs 120 in the first category and UEs 120 in the second category). 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 simplified 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.

[0071] 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 communicating through a network node 110 acting as an intermediary). As an example, UE 120a can send data, control information, or other signaling directly 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.

[0072] 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.

[0073] 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 technology typically utilizes 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 radio access technologies (RATs) can employ advanced MIMO techniques such as mTRP operation (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).

[0074] In some aspects, the UE (e.g., UE 120) may include a communication manager 140. As described in more detail elsewhere herein, the communication manager 140 may receive configuration information indicating carrier aggregation configuration associated with a first CC and a second CC; receive scheduling information indicating at least one scheduled transmission during a transmission timing associated with at least one of the first CC or the second CC; and use at least one transmission power during the transmission timing to transmit at least one communication on at least one of the first CC or the second CC, the at least one transmission power including a first transmission power associated with the first CC, wherein the first transmission power is at least partially based on a first maximum transmission power limit associated with the first CC and a first PHR reference value associated with the first CC, and wherein the first PHR reference value is determined independently of the first maximum transmission power limit. Additionally or alternatively, the communication manager 140 may perform one or more other operations described herein.

[0075] In some aspects, a network node (e.g., network node 110) may include a communication manager 150. As described in more detail elsewhere herein, the communication manager 150 may transmit configuration information indicating carrier aggregation configuration associated with a first CC and a second CC; transmit scheduling information indicating at least one scheduled transmission during a transmission timing associated with at least one of the first CC or the second CC; and use at least one transmission power during the transmission timing to receive at least one communication on at least one of the first CC or the second CC, the at least one transmission power including a first transmission power associated with the first CC, wherein the first transmission power is at least partially based on a first maximum transmission power limit associated with the first CC and a first PHR reference value associated with the first CC, and wherein the first PHR reference value is determined independently of the first maximum transmission power limit. Additionally or alternatively, the communication manager 150 may perform one or more other operations described herein.

[0076] 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.

[0077] Figure 2 This is a diagram illustrating an example network node 110 communicating with an example UE 120 in a wireless network according to the present disclosure.

[0078] 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.

[0079] The terms “processor,” “controller,” or “controller / processor” can refer to one or more controllers and / or one or more processors. For example, references to “a / the processor,” “a / the 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.

[0080] 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 the same set of processors or can be 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 combined... 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.

[0081] 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 channel state information (CSI) reference signals (CSI-RS)) and / or synchronization signals (e.g., primary synchronization signal (PSS) or secondary synchronization signal (SSS)).

[0082] 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 up-convert) the output sample stream to obtain a time-domain downlink signal. Modems 232a to 232t may transmit the set of downlink signals (e.g., [missing information]) together via a set of corresponding antennas 234. T (One downlink signal).

[0083] 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.

[0084] 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 where applicable by MIMO detector 236 (e.g., receive (Rx) MIMO processor), 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.

[0085] 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.

[0086] 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 analog signals (such as those used for transmission or reception via an air interface) to 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.

[0087] 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.

[0088] UE 120 may include a set of antennas 252 (shown as antennas 252a to 252r, where r ≥ 1), a set 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.

[0089] 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 transmit the set of received 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, may perform MIMO detection on the received symbols where applicable, and may provide the detected symbols. Receiver processor 258 may process (e.g., decode) the detected symbols, may 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 may provide the decoded control information and system information to controller / processor 280.

[0090] 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). These one or more parameters may include a Reference Signal Received Power (RSRP) parameter, a Received Signal Strength Indicator (RSSI) parameter, a Reference Signal Received Quality (RSRQ) parameter, a Channel Quality Indicator (CQI) parameter, or a Transmit Power Control (TPC) parameter, etc. The control information may include indications of the RSRP parameter, RSSI parameter, RSRQ parameter, CQI parameter, TPC parameter, and / or another parameter. Control information can facilitate parameter selection and / or scheduling for UE 120 by network node 110.

[0091] Transmit processor 264 can generate reference symbols for one or more reference signals, such as uplink DMRS, uplink SRS, and / or another type of reference signal. Symbols from transmit processor 264 may be pre-decoded by TX MIMO processor 266 where applicable, and further processed by an assembly of modems 254 (e.g., for DFT-s-OFDM or CP-OFDM). TX MIMO processor 266 can (where applicable) perform spatial processing (e.g., pre-decoding) on ​​data symbols, control symbols, overhead symbols, and / or reference symbols, and can provide an output symbol stream set (e.g., ...) to the assembly of modems 254. U 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.

[0092] Modems 254a to 254u can transmit uplink signal sets (e.g., via a set of corresponding 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., transmissions made 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).

[0093] 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.

[0094] 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, which can be used to independently transmit cross-polarized signals. 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.

[0095] 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.

[0096] 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).

[0097] 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.

[0098] Figure 3 This is an illustration of an example decomposed base station architecture 300 according to the present disclosure. One or more components of the example decomposed base station architecture 300 may be, may include, or may be included in one or more network nodes (such as one or more network nodes 110). The decomposed 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 decomposed 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, a UE 120 may be served simultaneously by multiple RU 340s.

[0099] Each of the components of the decomposed 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.

[0100] In some respects, the CU 310 can be logically divided into one or more CU-UP units and one or more CU-CP units. When implemented in an O-RAN configuration, the CU-UP units 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.

[0101] 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.

[0102] The non-RT RIC 350 may include or implement logical functions that enable non-real-time control and optimization of RAN elements and resources, including artificial intelligence / machine learning (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 logical 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 actions, connecting one or more CU 310s, one or more DU 330s, and / or O-eNBs to the near-RT RIC 370.

[0103] 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 employ AI / ML models to perform corrective actions 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).

[0104] 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.

[0105] 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 a stable PHR reference for carrier aggregation, 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 a stable PHR reference for carrier aggregation, 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 7 Process 700 Figure 8The operation of process 800 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 instruction sets (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 instruction set may be made to 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 7 Process 700 Figure 8 The process 800 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.

[0106] In some aspects, the UE (e.g., UE 120) includes: means for receiving configuration information indicating carrier aggregation configuration associated with a first CC and a second CC; means for receiving scheduling information indicating at least one scheduled transmission during a transmission timing associated with at least one of the first CC or the second CC; and / or means for transmitting at least one communication on at least one of the first CC or the second CC using at least one transmission power during the transmission timing, the at least one transmission power including a first transmission power associated with the first CC, wherein the first transmission power is at least partially based on a first maximum transmission power limit associated with the first CC and a first PHR reference value associated with the first CC, and wherein the first PHR reference value is determined independently of the first maximum transmission power limit. Components for the UE to perform the operations described herein may include, for example, one or more of 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.

[0107] In some aspects, a network node (e.g., network node 110) includes: components for transmitting configuration information indicating carrier aggregation configuration associated with a first CC and a second CC; components for transmitting scheduling information indicating at least one scheduled transmission during a transmission timing associated with at least one of the first CC or the second CC; and / or components for receiving at least one communication on at least one of the first CC or the second CC using at least one transmission power during the transmission timing, the at least one transmission power including a first transmission power associated with the first CC, wherein the first transmission power is at least partially based on a first maximum transmission power limit associated with the first CC and a first PHR reference value associated with the first CC, and wherein the first PHR reference value is determined independently of the first maximum transmission power limit. 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 220, a TX MIMO processor 230, 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.

[0108] Carrier aggregation is a technique that enables two or more component carriers (CCs, sometimes referred to as carriers) to be combined (e.g., combined into a single channel) for a single UE to enhance data capacity. Carriers in the same or different frequency bands can be combined. Additionally or alternatively, contiguous or discontinuous carriers can be combined. Network nodes can configure carrier aggregation for a UE, such as in Radio Resource Control (RRC) messages, Downlink Control Information (DCI) messages, and / or other signaling messages.

[0109] In some aspects, carrier aggregation can be configured in an intra-band continuous mode, where the aggregated carriers are consecutive and in the same frequency band. In some aspects, carrier aggregation can be configured in an intra-band discontinuous mode, where the aggregated carriers are discontinuous and in the same frequency band. In some aspects, carrier aggregation can be configured in an inter-band discontinuous mode, where the aggregated carriers are discontinuous and in different frequency bands.

[0110] In carrier aggregation, a UE can be configured with 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 other 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.

[0111] Figure 4A and Figure 4BThis is an illustration of example 400 / 480 associated with determining power transmission related to a CA configuration according to this disclosure. Figure 4A As shown, UE 402 and network node 404 can communicate with each other.

[0112] As shown by reference numeral 406, UE 402 can determine the transmission power (e.g., one or more transmission powers), and as shown by reference numeral 408, UE 402 can transmit at least one communication. For example, UE 402 can use the determined transmission power to transmit at least one communication.

[0113] In some cases, for example, UE 402 may be configured with a carrier aggregation (CA) configuration indicating a first component carrier (CC) and a second CC. The first CC may be associated with a first frequency band, and the second CC may be associated with a second frequency band. As shown by reference numeral 410, UE 402 may be configured to determine whether scheduling information indicates that parallel transmissions will occur during a transmission timing period. For example, parallel transmissions may be two or more transmissions scheduled to be transmitted within the same transmission timing and at least partially overlapping in the time domain. Non-parallel transmissions may be two or more transmissions that at least partially do not overlap in the time domain.

[0114] If parallel transmission is used to schedule transmission timing, UE 402 can use operation 412, based on the CA-based power class (shown as "powerClass") 414, to determine the first maximum transmission power limit Pcmax1 associated with the first CC. UE 402 can use operation 416, based on the CA-based power class 414, to determine the second maximum transmission power limit Pcmax1 associated with the second CC. CMAX2 (It can also be called "Pcmax2" or "P") CMAX_CC2 UE 402 may, as part of operation 412, determine a first PHR reference value associated with the first CC (shown as "PHR Limit 1", and may also be referred to as "PHR"). CC1 (For example, in conjunction with determining P) CMAX1 It can also be called "Pcmax1" or "PC". MAX_CC1 ), and as part of operation 416, determine a second PHR reference value associated with the second CC (shown as "PHR Limit 2", and may also be referred to as "PHR"). CC2 In some cases, the corresponding PHR limit may be based on the corresponding maximum transmit power limit and / or the power level of CA 414. UE 402 may determine the first transmit power 426 based on Pcmax1 and PHR limit 1, and / or determine the second transmit power 428 based on Pcmax2 and PHR limit 2.

[0115] If transmission timing is scheduled using only one communication and / or two or more non-parallel communications, UE 402 may use operation 412 to determine a first maximum transmit power limit Pcmax1 based on a first per-band UE power class (shown as "1 ue-PowerClass") 418 and a first per-band and per-band combined UE power class (shown as "1 ue-PowerClassPerBandPerBC-17") 420. Similarly, UE 402 may use operation 416 to determine a second maximum transmit power limit Pcmax2 based on a second per-band UE power class 422 (shown as "2 ue-PowerClass") and a per-band and per-band combined UE power class 424 (shown as "2 ue-PowerClassPerBandPerBC-r17"). UE 402 may determine PHR limit 1 based on the first per-band UE power class 418 and the first per-band and per-band combined UE power class 420. Similarly, as part of operation 416 (e.g., in conjunction with determining Pcmax2), UE 402 may determine a second PHR reference value (shown as "PHR Limit 2") associated with the second CC. In some cases, for example, PHR Limit 2 may be determined based on the second per-band UE power class (shown as "2nd ue-PowerClass") 422 and the second per-band and per-band combined UE power class (shown as "2nd ue-PowerClassPerBandPerBC-17") 424.

[0116] like Figure 4B As shown, UE 402 can determine the first transmit power (shown as "P") of the first CC (shown as "CC1") and the second CC (shown as "CC2"), respectively. CC1 ") and the second transmission power (shown as "P") CC2 Each transmission power is based on the corresponding maximum transmission power (P). CMAX The maximum transmit power and the corresponding power headroom limit (PHR), along with other parameters, are derived as described above. Similarly, the maximum transmit power and the corresponding power headroom limit are derived from a set of parameters (“params”), as described above. For example, for CC1, UE 402 can use the set of parameters params as described above. a 482 to determine the maximum transmission power P CMAX_CC1 484 and Power Clearance Limit (PHR) CC1 486 (For example, UE 402 may determine the first transmit power P based on it) CC1 488). Similarly, for CC2, UE 402 can use the parameter set params. b492 to determine the maximum transmission power P CMAX_CC2 494 and Power Clearance Limit (PHR) CC2 496 (For example, UE 402 can determine the second transmit power P based on it) CC2 498).

[0117] As described above, if parallel transmission is used to schedule transmission timing, the first maximum transmission power limit associated with the first CC is determined by UE 402 based on the power level of CA. In other words, UE 402 determines the maximum transmission power limit based on params. a 482 to determine P CMAX_CC1 484. Similarly, as described above, UE 402 combines the determination of P CMAX_CC1 To determine the first PHR reference value associated with the first CC. In other words, UE 402 determines the PHR reference value from it. CMAX_CC1 484 identical params a At least one of 482 determines the PHR CC1 486. Therefore, P CC1 Based on params a 482 Export P CMAX_CC1 484 and PHR CC1 It was exported using 486. Regarding params... b 492, P CMAX_CC2 494, PHR CC2 496 and P CC2 A similar operation occurs on CC2, as described above.

[0118] In some cases, to facilitate scheduling by network node 404 and / or for appropriate resource allocation received at network node 404, UE 402 may declare a power level with one or more capabilities (e.g., via UE capability information and / or PHR reporting). One or more capabilities may include, for example, per-band UE power level, per-band and per-band combined UE power level and / or CA power level, etc. In some cases, when different power levels are declared between two bands in the CA, UE 402 may use higherPowerLimit-r17 per-band combination to indicate a larger combined power limit.

[0119] For example, in some cases, UE 402 may declare a power level for PC2 associated with the first CC, a power level for PC3 associated with the second CC, and a power level for PC3 associated with CA. In another case, for example, UE 402 may declare a power level for PC2 associated with the first CC, a power level for PC3 associated with the second CC, and a power level for PC3 associated with CA. In some cases, even if CC1 (e.g., the first band) and CC2 (e.g., the second band) have the same output power capability in both cases, UE 402 may choose to declare either PC3 or PC2 in CA because PC2 can fall back to PC3. In one or more examples, UE 402 may use ue-PowerClassPerBandPerBC-r17 to declare the maximum power associated with each band. For example, ue-PowerClassPerBandPerBC-r17 may be optionally used regardless of whether the maximum output power capability associated with CC1 is 23dBm or 26dBm in CA.

[0120] However, in some cases, the wireless communication standard may be ambiguous regarding when to apply the power level of the CA. Because the power level of the CA can limit transmit power, resolving this ambiguity can lead to more efficient and / or effective communication. Furthermore, in some cases, the UE may declare a first power level associated with a CC, but ultimately use a second power level for the CC (e.g., as a result of using the power level for the CA instead). For example, the power level of the CA may be used in: 1) when both CCs are configured, 2) when both CCs are active, or 3) when both CCs are scheduled. In some cases, the wireless communication standard may specify that the power level of the CA will be used in: 1) when both CCs are configured. However, in some cases, although two CCs can be configured, network node 404 may allocate resources (e.g., schedule) for communication on only one CC or the other for a given transmission timing. Therefore, in some cases, option 3 (where the power level of the CA is used when both CCs are scheduled) may be the most efficient of the three options because if only one band is permitted to transmit, power limitation is not required.

[0121] In some cases, if Option 3 is used in the implementation, the PHR reference value can change based on transmissions on another CC. This can cause confusion from the perspective of network node 404, as the PHR may appear to change sporadically, for example, when only one CC is observed. Therefore, if network node 404 has more accurate information relating to the power level that UE 402 will actually use, network node 404 can be more efficient and / or effective in allocating resources for actual transmissions.

[0122] Some aspects of the techniques described herein can facilitate providing a stable PHR reference value for carrier aggregation. For example, some aspects may include separating the calculation of the PHR reference value from the calculation of the maximum transmit power. In some aspects, separating the calculation of the PHR reference value from the calculation of the maximum transmit power allows the PHR reference value to be determined without considering the power level of the CA, thus obtaining a stable (e.g., the same) PHR reference value regardless of whether the power level of the CA is being used to determine the maximum transmit power, thereby enhancing the predictability of transmit power, since transmit power is limited by the PHR reference value. In some aspects, the UE may determine the PHR reference value based on the per-band UE power level and the per-band and per-band combined UE power levels. For example, the UE may determine the PHR reference value as the maximum of two power levels. In some cases, the PHR reference value of the CC can be determined in this way, regardless of whether the network node schedules overlapping or non-overlapping transmissions for transmission timing. In this way, several aspects can benefit from providing a stable PHR reference value, thereby improving the predictability of UE transmit power determination for two or more CCs, leading to more efficient resource scheduling and more effective reception of UE transmits at the network, which can have a positive impact on network and / or device performance.

[0123] As indicated above, Figure 4A and Figure 4B This is provided as an example. Other examples are available relative to... Figure 4A and Figure 4B The examples described are different.

[0124] Figures 5A to 5C These are illustrations of examples 500a, 500b, and 560, respectively, associated with a stable PHR reference used for carrier aggregation, according to this disclosure. Figure 5A As shown, UE 502 and network node 504 can communicate with each other. In some aspects, UE 502 and network node 504 can be part of a wireless network (e.g., wireless communication network 100). In some aspects, UE 502 can be, resemble, include, or be included in the following: Figure 4A and Figure 4B The UE 402 depicted, and / or Figures 1 to 3 The UE 120 is depicted. In some aspects, network node 504 may be, resemble, include, or be included in the following: Figure 4A and Figure 4B The network node described is 404. Figure 1 and Figure 2 The network node 110 and / or described Figure 3The depicted decomposed base station architecture 300 includes one or more components. In some aspects, network node 504 may include a first TRP configured to communicate on a first CC and a second TRP configured to communicate on a second CC. UE 502 and network node 504 may have established a radio connection prior to the operation shown in FIG. 5.

[0125] As indicated by reference numeral 506 in the accompanying drawings, network node 504 can transmit and UE 502 can receive scheduling information. The scheduling information may indicate one or more resources allocated during a transmission timing for transmitting one or more uplink communications. The scheduling information may indicate a first CC and / or a second CC. For example, in some aspects, the scheduling information may allocate time resources and / or frequency resources for transmitting a first communication on the first CC and a second communication on the second CC. In some aspects, the allocated resources may be associated with one transmission (e.g., a communication on the first CC or the second CC) during a transmission timing. In some aspects, the allocated resources may be associated with two transmissions (e.g., a first communication on the first CC and a second communication on the second CC) during a transmission timing. In some aspects, the two transmissions may be overlapping transmissions (e.g., the first communication may at least partially overlap with the second communication in the time domain) or non-overlapping transmissions (e.g., the first communication may not overlap with the second communication in the time domain).

[0126] As shown by reference numeral 508 in the accompanying drawings, UE 502 may determine one or more PHR reference values. For example, UE 502 may determine a first PHR reference value associated with a first CC and a second PHR reference value associated with a second CC. In some aspects, UE 502 may determine one or more PHR reference values ​​independently of determining one or more maximum transmit power limits. In some aspects, for example, the first PHR reference value may be determined based on a first per-band UE power class and a first per-band and per-band combined UE power class. For example, in some aspects, the first PHR reference value may be the maximum value among the first per-band UE power class and the first per-band and per-band combined UE power class. Similarly, in some aspects, the second PHR reference value may be determined based on a second per-band UE power class and a second per-band and per-band combined UE power class. For example, in some aspects, the second PHR reference value may be the maximum value among the second per-band UE power class and the second per-band and per-band combined UE power class.

[0127] As shown by reference numeral 510, UE 502 may determine one or more maximum transmit power limits (shown as "maximum transmit power limits"). The one or more maximum transmit powers may include a first maximum transmit power Pcmax1 associated with a first CC and a second maximum transmit power Pcmax2 associated with a second CC. The one or more maximum transmit powers may be determined independently of determining one or more PHR reference values. This can, in some aspects, facilitate providing a stable PHR reference value for each CC, even in scenarios involving carrier aggregation. As shown by reference numeral 512, UE 502 may determine one or more transmit powers (shown as "transmit power"). For example, in some aspects, the one or more transmit powers may be determined based on one or more maximum transmit powers and / or one or more PHR reference values. As shown by reference numeral 514, UE 502 may transmit and network node 504 may receive at least one communication. This at least one communication may include a first communication transmitted on the first CC (e.g., using a first determined transmit power) and / or a second communication transmitted on the second CC (e.g., using a second determined transmit power).

[0128] Figure 5B Example 500b describes in Figure 5A Some examples of determination are described in the context of Example 500a. As shown by reference numeral 512, UE 502 may determine a transmit power (e.g., one or more transmit powers), and as shown by reference numeral 514, UE 502 may transmit at least one communication. For example, UE 502 may use the determined transmit power to transmit at least one communication. In some aspects, Example 500 depicts a situation related to... Figure 4A The scenario depicted in Example 400 is similar to that described herein, but in which UE 502 implements one or more aspects of the techniques described herein associated with a stable PHR reference value for CA.

[0129] In some cases, for example, UE 502 may be configured with a CA configuration indicating a first CC and a second CC. The first CC may be associated with a first frequency band, and the second CC may be associated with a second frequency band. As shown by reference numeral 516, UE 502 may be configured to determine whether scheduling information indicates that parallel transmission will occur during a transmission timing period. If the transmission timing is scheduled with parallel transmission, UE 502 may use operation 518 based on the power class (shown as "powerClass") 520 of CA to determine a first maximum transmission power limit Pcmax1 associated with the first CC. UE 502 may use operation 522 based on the power class of CA 520 to determine a second maximum transmission power limit Pcmax2 associated with the second CC.

[0130] In Example 500b, as part of Operation 518, UE 502 may not determine the first PHR reference value. Instead, as shown in Operation 524, UE 502 may determine the first PHR reference value independently of determining the first maximum transmit power limit in Operation 518. In some aspects, for example, UE 502 may determine the first PHR reference value based on a first per-band UE power class 526 and a first per-band and per-band combined UE power class 528. For example, in some aspects, the first PHR reference value may be equal to the maximum value among the first per-band UE power class 526 and the first per-band and per-band combined UE power class 528. The PHR reference value determined using Operation 524 may be applied to the first CC, regardless of whether UE 502 transmits one or two communications and / or whether the two communications are transmitted according to CA.

[0131] UE 502 may use operation 530 to determine a second PHR reference value (shown as "PHR Limit 2") associated with the second CC. In example 500b, as part of operation 522, UE 502 may not determine the second PHR reference value. Instead, as shown in operation 530, UE 502 may determine the second PHR reference value independently of determining the second maximum transmit power limit in operation 522. In some aspects, for example, UE 502 may determine the second PHR reference value based on a second per-band UE power class 532 and a second per-band and per-band combined UE power class 534. For example, in some aspects, the second PHR reference value may be equal to the maximum value of the second per-band UE power class 532 and the second per-band and per-band combined UE power class 534. The PHR reference value determined using operation 530 may be applied to the first CC, regardless of whether UE 502 transmits one or two communications and / or whether the two communications are transmitted according to CA.

[0132] UE 502 may determine a first transmit power 536 based on Pcmax1 and PHR limit 1, and / or determine a second transmit power 538 based on Pcmax2 and PHR limit 2.

[0133] like Figure 5C As shown, UE 502 can determine the first transmit power (shown as "P") of the first CC (shown as "CC1") and the second CC (shown as "CC2"), respectively. CC1 ") and the second transmission power (shown as "P") CC2 Each transmission power is based on the corresponding maximum transmission power (P). CMAXThe maximum transmit power and the corresponding power headroom limit (PHR), along with other parameters, are derived as described above. Similarly, the maximum transmit power and the corresponding power headroom limit are derived from a set of parameters (“params”), as described above. For example, for CC1, UE 502 can use the first set of parameters, params, as described above. a 562 to determine the maximum transmission power P CMAX_CC1 564 and using the second parameter set params b 566 to determine the power headroom limit (PHR) CC1 568 (For example, UE 502 may determine the first transmit power P based on it) CC1 570). Similarly, for CC2, UE 502 can use the third parameter set params. c 572 to determine the maximum transmission power P CMAX_CC2 574 and using the fourth parameter set params d 576 to determine the power headroom limit (PHR) CC2 578 (For example, UE 502 may determine the second transmit power P based on it) CC2 580).

[0134] As described above, the first maximum transmit power limit associated with the first CC is determined by UE 502 in the first operation and based on the power level of CA. In other words, UE 502 determines this limit based on params. a 562 to determine P CMAX_CC1 564. Similarly, as described above, UE 502 operates in a separate manner and independently of determining P. CMAX_CC1 To determine the first PHR reference value associated with the first CC. In other words, to determine the PHR based on it. CMAX_CC1 564 params a 562 separately, UE 502 according to params b 566 to determine PHR CC1 568. Therefore, P CC1 It is independent of different parameter sets (e.g., in different operations) based on derived P CMAX_CC1 564 and PHR CC1 It was exported from 568. Regarding params... c 572 and P CMAX_CC2 574, params d 576 and PHR CC2 578, and P CC2 A similar set of independent operations occurs on CC2, as described above.

[0135] As indicated above, Figures 5A to 5C This is provided as an example. Other examples are available with reference to [the relevant information]. Figures 5A to 5C The examples described are different.

[0136] Figure 6A and Figure 6B These are illustrations of examples 600 and 650, respectively, associated with a stable PHR reference used for carrier aggregation, according to this disclosure. Figure 6A As shown, UE 602 and network node 604 can communicate with each other. In some aspects, UE 602 and network node 604 can be part of a wireless network (e.g., wireless communication network 100). In some aspects, UE 602 can be, resemble, include, or be included in: UE 502 depicted in Figure 5, Figure 4A and Figure 4B The UE 402 and / or described Figures 1 to 3 The UE 120 depicted. In some aspects, network node 604 may be, resemble, include, or be included in the following: network node 504 depicted in Figure 5, Figure 4A and Figure 4B The network node described is 404. Figure 1 and Figure 2 The network node 110 and / or described Figure 3 The depicted decomposed base station architecture 300 includes one or more components. In some aspects, actions described as being performed by network node 604 can be performed by multiple different network nodes 604. For example, configuration actions can be performed by a first network node 604 (e.g., CU and / or DU), and radio communication actions can be performed by a second network node 604 (e.g., DU and / or RU). In some aspects, network node 604 may include a first transmit / receive point (TRP) configured to communicate on a first CC and a second TRP configured to communicate on a second CC. UE 602 and network node 604 may... Figure 6A The operation shown has been performed after a wireless connection has been established.

[0137] As shown by reference numeral 606 in the accompanying drawings, UE 602 may transmit UE capability information (directly or via one or more other UEs and / or network nodes), and network node 604 may receive the UE capability information. In some aspects, the UE capability information may indicate UE capabilities supporting carrier aggregation. In some aspects, the UE capability information may indicate capabilities for supporting a stable PHR for carrier aggregation, as described herein.

[0138] As indicated by reference numeral 608 in the accompanying drawings, network node 604 may send (or transmit) configuration information (directly or via one or more other network nodes), and UE 602 may receive (or obtain) the configuration information. In some aspects, UE 602 may receive the configuration information via RRC signaling, one or more MAC-CEs and / or DCIs, etc. In some aspects, the configuration information may include indications of one or more configuration parameters selected by UE 602 (e.g., those already known to UE 602 and / or previously indicated by network node 604 or another network device) and / or explicit configuration information for UE 602 to use in configuring UE 602, etc. In some aspects, the configuration information may include any number of communications providing the configuration information. The configuration information may be or include one or more configurations, portions of one or more configurations, parameter values ​​associated with one or more configurations (e.g., associated with parameters of the configuration), and / or any other type of information that can be used to configure UE 602 with a first CC and a second CC in the context of a carrier aggregation configuration, etc. For example, the configuration information may include a carrier aggregation configuration indicating a first CC and a second CC. In some respects, UE 602 may configure itself at least in part based on received configuration information. In some respects, UE 602 may be configured to perform one or more operations described herein, at least in part based on configuration information.

[0139] As shown by reference numeral 610 in the accompanying drawings, network node 604 may send (or transmit) scheduling information (directly or via one or more other network nodes), and UE 602 may receive (or obtain) the scheduling information. The scheduling information may be carried, for example, via DCI, and may indicate time and / or frequency resources for UE 602 to send one or more uplink signals to network node 604. In some examples, the scheduling information may instruct UE 602 to send one communication during a transmission period. In some examples, the scheduling information may instruct UE 602 to send two communications during a transmission period. For example, in some aspects, the scheduling information may schedule overlapping and / or non-overlapping communications. The scheduled communications may be associated with a first CC and / or a second CC.

[0140] As shown by reference numeral 612 in the attached figure, UE 602 may determine one or more transmit powers (shown as "transmit power") to be used for transmitting one or more scheduled communications. For example, UE 602 may determine a first transmit power associated with a first CC. UE 602 may determine this based at least in part on a first maximum transmit power limit P associated with the first CC. CMAX The first transmit power is determined by a first PHR reference value associated with the first CC. In some aspects, UE 602 may determine the PHR reference value independently of the first maximum transmit power limit.

[0141] In some aspects, for example, the first PHR reference value may be the maximum value among the first per-band UE power level and the first per-band and per-band combined UE power levels associated with the carrier aggregation configuration. In some aspects, at least one scheduled communication includes only the first communication associated with the first CC during the transmission timing. In some aspects, based on the fact that at least one scheduled communication includes only the first transmission during the transmission timing, the first maximum transmission power limit may be based on the first per-band UE power level and the first per-band and per-band combined UE power level.

[0142] In some aspects, at least one scheduled transmission may include two parallel transmissions during the transmission timing, and the first maximum transmission power limit may be based at least in part on a carrier aggregation power level. At least one transmission power may include a second transmission power associated with a second CC. The second transmission power may be based on a second maximum transmission power limit, which is at least in part based on a carrier aggregation power level.

[0143] In some aspects, at least one scheduled transmission may include two non-parallel transmissions during the transmission timing, and the first maximum transmission power limit may be based at least in part on a first per-band UE power class. The at least one transmission power may also include a second transmission power associated with a second CC. The second transmission power may be based at least in part on a second PHR reference value associated with the second CC. The second PHR reference value may include the maximum of the second per-band UE power class and the second per-band and per-band combined UE power class associated with carrier aggregation. In some aspects, the second transmission power may be based on a second maximum transmission power limit. The second maximum transmission power limit may be based at least in part on a second per-band UE power class. The second PHR reference value may be determined independently of the second maximum transmission power limit.

[0144] As shown by reference numeral 614 in the attached figure, UE 602 may send (or transmit) a PHR report (directly or via one or more other network nodes), and network node 604 may receive (or obtain) the PHR report. The PHR report may indicate a first PHR reference value and / or a second PHR reference value, etc., based on scheduling information.

[0145] As shown by reference numeral 616 in the accompanying drawings, UE 602 may (directly or via one or more other network nodes) send (or transmit) at least one communication, and network node 604 may receive (or acquire) at least one communication. In some aspects, a first transmit power and / or a second transmit power may be used to send at least one communication. Because the first transmit power and the second transmit power may be based on a reported PHR reference value, network node 604 may be able to appropriately schedule and / or receive at least one communication. In this regard, in some aspects, after UE 602 sends a PHR report to network node 604, network node 604 may send and UE 602 may receive scheduling information.

[0146] like Figure 6B As shown, UE 602 and network node 604 can communicate with each other across carrier sets CC1 (shown by reference numeral 654-1) and CC2 (shown by reference numeral 654-2). For example, network node 604 may include a first TRP configured to communicate on the first CC 654-1 and a second TRP configured to communicate on the second CC 654-2. UE 602 and network node 604 can... Figure 6B The operation shown has been performed after a wireless connection has been established.

[0147] As indicated by reference numeral 656 in the accompanying drawings, network node 604 may send (or transmit) configuration information (directly or via one or more other network nodes), and UE 602 may receive (or obtain) configuration information as described above. For example, UE 602 may receive configuration information via RRC signaling, one or more MAC-CEs and / or DCIs, etc. In some aspects, configuration information may include indications of one or more configuration parameters selected by UE 602 (e.g., those already known to UE 602 and / or previously indicated by network node 604 or another network device) and / or explicit configuration information for UE 602 to use in configuring UE 602, etc. In some aspects, configuration information may include any number of communications providing configuration information. Configuration information may be or include one or more configurations, portions of one or more configurations, parameter values ​​associated with one or more configurations (e.g., associated with parameters of the configuration), and / or any other type of information that can be used to configure UE 602 with a first CC 654-1 and a second CC 654-2 in the context of carrier aggregation configuration, etc. For example, the configuration information may include carrier aggregation configurations indicative of the first CC 654-1 and the second CC 654-2. In some aspects, the UE 602 may configure itself at least in part based on the received configuration information. In some aspects, the UE 602 may be configured to perform one or more of the operations described herein, at least in part based on the configuration information.

[0148] As shown by reference numeral 658 in the accompanying drawings, network node 604 may send (or transmit) scheduling information (directly or via one or more other network nodes), and UE 602 may receive (or obtain) the scheduling information. The scheduling information may be carried, for example, via DCI, and may indicate time and / or frequency resources for UE 602 to send one or more uplink signals to network node 604. In some examples, the scheduling information may instruct UE 602 to send one communication during a transmission timing period. In some examples, the scheduling information may instruct UE 602 to send two communications during a transmission timing period. For example, in some aspects, the scheduling information may schedule overlapping and / or non-overlapping communications. The scheduled communications may be associated with a first CC 654-1 and / or a second CC 654-2.

[0149] As shown by reference numeral 660 in the attached figure, UE 602 may determine one or more transmit powers (shown as "transmit power") to be used for transmitting one or more scheduled communications. For example, UE 602 may determine a first transmit power associated with a first CC 654-1. UE 602 may determine this power at least in part based on a first maximum transmit power limit P associated with the first CC 654-1. CMAX The first transmit power is determined by a first PHR reference value associated with the first CC 654-1. In some aspects, the UE 602 may determine the PHR reference value independently of the first maximum transmit power limit.

[0150] In some aspects, for example, the first PHR reference value may be the maximum of the first per-band UE power level and the first per-band and per-band combined UE power levels associated with the carrier aggregation configuration. In some aspects, at least one scheduled communication includes only the first communication associated with the first CC 654-1 during the transmission timing. In some aspects, based on the fact that at least one scheduled communication includes only the first transmission during the transmission timing, the first maximum transmission power limit may be based on the first per-band UE power level and the first per-band and per-band combined UE power levels.

[0151] In some aspects, at least one scheduled transmission may include two parallel transmissions during the transmission timing, and the first maximum transmission power limit may be based at least in part on the carrier aggregation power level.
