Description

[0001] Priority / Incorporation by reference

[0002] This application claims priority to U.S. Provisional Application Serial No. 63 / 516,662, filed July 31, 2023, entitled “Panel-Specific Power Control for Multi-Panel Operations,” the entire contents of which are incorporated herein by reference. Background Technology

[0003] User equipment (UE) can have multiple transmit antenna panels, enabling UEs to perform multi-panel transmission (referred to as simultaneous multi-panel (STxMP) transmission). Multi-panel transmission provides enhanced uplink coverage and average throughput for multi-panel UEs. When using STxMP transmission, the transmit power of multiple panels will remain within acceptable transmit power limits. Therefore, transmit power sharing among multiple panels should be defined. Furthermore, the method of signaling to the UE how transmit power should be shared among panels should also be defined. Summary of the Invention

[0004] Some example implementations relate to an apparatus having processing circuitry configured to: decode a configured maximum transmit power based on signaling received from a base station, wherein the signaling is radio resource control (RRC) signaling; and generate uplink transmissions not exceeding the configured maximum transmit power for simultaneous transmissions via a first antenna panel and a second antenna panel.

[0005] Other example implementations involve a method comprising: receiving a configured maximum transmit power, wherein the signaling is radio resource control (RRC) signaling; and simultaneously transmitting uplink transmissions via a first antenna panel and a second antenna panel, not exceeding the configured maximum transmit power.

[0013] The example embodiments can be further understood by referring to the following description and related figures, wherein similar elements have the same reference numerals. The example embodiments relate to improved power utilization for STxMP transmission.

[0014] Example embodiments are described with reference to user equipment (UE). However, references to the UE are provided for illustrative purposes only. The example embodiments can be used with any electronic component capable of establishing a connection to a network and configured with hardware, software, and / or firmware for exchanging information and data with the network. Therefore, the UE described herein is used to represent any electronic component.

[0015] Example implementations are also described with reference to 5G New Radio (NR) networks. These example implementations can also be implemented in other types of networks, including but not limited to LTE networks, future evolutions of cellular protocols (e.g., 6G networks), or any other type of network.

[0016] This document discloses the operation and logic related to STxMP power reduction. Specifically, the example implementations involve logic considering different power amplifier (PA) specific implementations. The example implementations cover both panel-specific maximum power determination logic and panel power scaling logic.

[0017] Figure 1 An example network arrangement 100 according to various example implementations is shown. Example network arrangement 100 includes a UE 110. UE 110 can be any type of electronic component configured to communicate via a network, such as a mobile phone, tablet computer, desktop computer, smartphone, phablet, embedded device, wearable device, Internet of Things (IoT) device (including connected vehicles), etc. A real network arrangement may include any number of UEs used by any number of users. Therefore, for illustrative purposes, only an example of UE 110 is provided.

[0018] UE 110 can be configured to communicate with one or more networks. In the example of network configuration 100, the network with which UE 110 can wirelessly communicate is the 5G NR Radio Access Network (RAN) 120. UE 110 can also communicate with other types of networks (e.g., 5G cloud RAN, next-generation RAN (NG-RAN), legacy cellular networks, etc.), and UE 110 can also communicate with the network via a wired connection. Referring to the example implementation, UE 110 can establish a connection with 5G NR RAN 120. Therefore, UE 110 may have a 5G NR chipset to communicate with NR RAN 120.

[0019] 5G NR RAN 120 can be part of a cellular network that can be deployed by a network operator (e.g., Verizon, AT&T, T-Mobile, etc.). RAN 120 can include cells or base stations configured to transmit and receive services from UEs equipped with appropriate cellular chipsets. In this example, 5G NR RAN 120 includes gNB 120A. However, the reference to gNB is provided merely for illustrative purposes, and any appropriate base station or cell can be deployed (e.g., Node B, eNodeB, HeNB, eNB, gNB, gNodeB, macro cell, micro cell, small cell, femtocell, etc.).

[0020] Any association procedure can be performed to connect UE 110 to 5G NR RAN 120. For example, as described above, 5G NR RAN 120 can be associated with a specific network operator where UE 110 and / or its user have protocol and credential information (e.g., stored on a SIM card). Upon detecting the presence of 5G NR RAN 120, UE 110 can send the corresponding credential information to associate with 5G NR RAN 120. More specifically, UE 110 can be associated with a specific cell (e.g., gNB 120A).

[0021] Network deployment 100 also includes a cellular core network 130, an Internet 140, an IP Multimedia Subsystem (IMS) 150, and a network services backbone 160. The cellular core network 130 manages traffic flowing between the cellular network and the Internet 140. The IMS 150 can generally be described as an architecture for delivering multimedia services to the UE 110 using IP protocols. The IMS 150 can communicate with the cellular core network 130 and the Internet 140 to provide multimedia services to the UE 110. The network services backbone 160 communicates directly or indirectly with the Internet 140 and the cellular core network 130. The network services backbone 160 can generally be described as a collection of components (e.g., servers, network storage deployments, etc.) that implement a set of services that can be used to extend the functionality of the UE 110 in communicating with various networks.

[0022] Figure 2 Example UE 110 according to various example implementations is shown. (Refer to...) Figure 1 The network layout 100 is used to describe UE 110. UE 110 can represent any electronic device and may include processor 205, memory layout 210, display device 215, input / output (I / O) device 220, transceiver 225, and other components 230. Other components 230 may include, for example, audio input devices, audio output devices, batteries providing a limited power source, data acquisition devices, ports for electrically connecting UE 110 to other electronic devices, sensors for detecting the status of UE 110, etc. Other components 230 may also include antenna elements communicatively coupled to transceiver 225. As will be described in more detail below, antenna elements may include multiple antenna panels located at various locations on or within UE 110.

[0023] Processor 205 can be configured to execute multiple engines of UE 110. For example, an engine may include STxMP engine 235 for performing operations related to determining a specific maximum power of the processing panel, as well as performing panel power scaling operations.

[0024] The engines described above, as applications (e.g., programs) executed by processor 205, are merely exemplary. The functionality associated with these engines may also be represented as separate, combined components of UE 110, or as modular components coupled to UE 110, such as integrated circuits with or without firmware. For example, the integrated circuit may include input circuitry for receiving signals and processing circuitry for processing signals and other information. The engine may also be embodied as one or more separate applications. Furthermore, in some UEs, the functionality described for processor 205 is split between two or more processors, such as a baseband processor and an application processor. Example implementations may be implemented according to any of these or other configurations of the UE.

[0025] Memory arrangement 210 may be a hardware component configured to store data related to operations performed by UE 110. Display device 215 may be a hardware component configured to display data to a user, while I / O device 220 may be a hardware component enabling a user to input data. Display device 215 and I / O device 220 may be separate components or may be integrated together (such as a touchscreen). Transceiver 225 may be a hardware component configured to establish a connection with 5G-NR RAN 120. Therefore, transceiver 225 may operate on a variety of different frequencies or channels (e.g., a continuous set of frequencies).

[0026] Transceiver 225 includes circuitry configured to transmit and / or receive signals (e.g., control signals, data signals). Such signals may be encoded using information used to implement any of the methods described herein. Processor 205 may be operatively coupled to transceiver 225 and configured to receive signals from and / or transmit signals to transceiver 225. Processor 205 may be configured to encode and / or decode signals (e.g., signaling from a base station in a network) for use in implementing any of the methods described herein.

[0027] Figure 3 An example base station 300 is shown according to various example implementations. Base station 300 may represent any other access node that the gNB 120A or UE 110 can use to establish connections and manage network operations.

[0028] Base station 300 may include processor 305, memory arrangement 310, input / output (I / O) devices 315, transceiver 320, and other components 325. These other components 325 may include, for example, audio input devices, audio output devices, batteries, data acquisition devices, ports for electrically connecting base station 300 to other electronic devices and / or power sources, etc.

[0029] The processor 305 may be configured to execute multiple engines of the base station 300. For example, the engines may include an STxMP engine 330 for performing operations related to sending signaling to the UE 110 (e.g., via RRC) to configure panel-specific maximum power limits, panel-specific power scaling, and panel priority ordering.

[0030] Memory 310 may be a hardware component configured to store data related to operations performed by base station 300. I / O device 315 may be a hardware component or port enabling a user to interact with base station 300. Transceiver 320 may be a hardware component configured to exchange data with UE 110 and any other UE in network arrangement 100. Transceiver 320 may operate on a variety of different frequencies or channels (e.g., a continuous set of frequencies). Therefore, transceiver 320 may include one or more components (e.g., radio components) to enable data exchange with various networks and UEs.

[0031] Transceiver 320 includes circuitry configured to transmit and / or receive signals (e.g., control signals, data signals). Such signals may be encoded using information used to implement any of the methods described herein. Processor 305 may be operatively coupled to transceiver 320 and configured to receive signals from and / or transmit signals to transceiver 320. Processor 305 may be configured to encode and / or decode signals (e.g., signaling from a UE) for use in implementing any of the methods described herein.

[0032] In a first aspect of the example implementation, various methods for determining the maximum transmit power for an antenna panel when implementing STxMP operation are disclosed. In the following example, two antenna panels are used. The principles disclosed herein for determining the maximum transmit power for an antenna panel can be extended to use more than two antenna panels.

[0033] Figure 4 A panel power diagram 400 is shown, relating to the determination of the maximum transmit power per panel for STxMP operation according to various example implementations. Panel power diagram 400 shows three examples (406, 408, and 410) of the first aspect. Panel power diagram 400 shows panels #0 402 and #1 404. Panels 402 and 404 are used in all three examples 406, 408, and 410 shown in panel power diagram 400. Additionally, the three examples 406, 408, and 410 shown have three in-band component carriers CC0, CC1, and CC2 configured for each panel in panels 402 and 404. Those skilled in the art will understand that... Figure 4 The dBm values ​​shown are merely examples, and other maximum transmit power values ​​are possible. For instance, the configured maximum transmit power value can be based on any relevant factors, such as regulatory requirements, interference, etc.

[0034] In the first example of the first aspect, it is possible to use Two maximum transmit power values ​​(e.g., individual values ​​for each panel) are configured for each component carrier of the serving cell via Radio Resource Control (RRC) signaling, where "f" is the component carrier, "c" is the serving cell, and "k" is the panel. For example, panel #0 402 can be indicated by k=0, and panel #1 404 can be indicated by k=1.

[0035] Return to Figure 4 In Example 1 406, the power value for each CC in each of antenna panels 402 and 404 can be explicitly configured via RRC signaling. For example, for CC1 on panel #0 402, the transmit power can be configured as 16 dBm. This can be indicated as... This shows that for CC1 on panel #0 402 of serving cell 1, the maximum transmit power can be 16 dBm. Similarly, for CC1 on panel #1 404, the transmit power can be configured as 13 dBm. This can be indicated as... This illustrates that for CC1 on panel #1 404 of serving cell 1, the maximum transmit power can be 13 dBm. Those skilled in the art will understand that the network can also be configured with similar configurations for the remaining CC / panel combinations. Therefore, in Example 1, the network configures a maximum transmit power for each panel and signals the value of the maximum transmit power to the UE.

[0036] In the second example of the first aspect, the carrier "f" of the serving cell "c" can be configured via RRC signaling. A single value, for example, a single maximum transmit power value for both panels. Signaling a single maximum transmit power value reduces signaling overhead compared to the first example, which signals two maximum transmit power values ​​for each CC. This configuration can introduce two scaling factors. and As The ratio of the linear threshold values. In the second example, In some variations of the second example, two scaling factors... and It can be applied to all CCs to allocate power P per CC. CMAX,f,c .

[0037] All scaling factors described in this document can be used by a UE to determine the maximum transmit power, which the UE can use by applying appropriate scaling factors to the configured maximum transmit power (e.g., per panel, per component carrier, etc.). Various examples of applying different scaling factors are provided below.

[0038] In the first option of the second example, ,include or To illustrate this in detail with examples, it can be assumed that... In one example, or In this example, the panels will share the maximum transmit power equally; for example, each panel is configured to use up to 50% of the configured maximum transmit power. In another example, or In this example, the panels will share the maximum transmit power unequally; for example, the first panel is configured to use up to 70% of the configured maximum transmit power, while the second panel is configured to use up to 30% of the configured maximum transmit power. As can be seen from these examples, when configuring the UE using the first part of the second example, the UE performing STxMP with both panels will never exceed the configured maximum transmit power.

[0039] Figure 4 Example 2 408 shows another example of the first option in the second example. Figure 4 In the example, for example 2 408, the maximum transmit power of CC0 and CC1 can be considered to be 21dBm, and the maximum transmit power of CC2 is 18dBm, but these values ​​are just examples.

[0040] To determine the dBm values ​​of CC0, CC1, and CC2 for Example 2 408, the following equation can be used: For example, the configuration of CC0 in Example 2 #408 could be... For example, the maximum transmit power of 21dBm and the equal scaling factor between each panel (panel #0 402 = 0.5 and panel #1 404 = 0.5). Using the above equation, Therefore, as Figure 4 As shown, both panel #0402 and panel #1404 will have a maximum transmit power value of 18dBm.

[0041] continue Figure 4 In Example 2 408, the power scaling values ​​for CC1 can be different from each other, for example, Using the equation for CC1 used in panel #0 402. Using the equation for CC1 used in panel #1 404, .

[0042] Finish Figure 4 Example 2 408 shows that the power scaling values ​​for CC2 can be different from each other, and The value can also be different from CC0 and CC1. Values, for example, Using the equation for CC2 panel #0 402, Using the equation for CC2 panel #1 404, Those skilled in the art will understand that any rounding scheme for the newly determined maximum transmit power used for the STxMP value is left to the operator to implement. Additionally, using different values ​​for different parameters (e.g., maximum transmit power, scaling factor) for each CC is merely an example. For instance, all CCs could have the same maximum transmit power and scaling factor.

[0043] For example, in the second option of the second example, the scaling factor can be operated without restriction, for example, or When the scaling factor is equal to or less than 100%, this option can be considered similar to the first option in the second example as described above, and will not be described further.

[0044] In the second option of the second example, the sum of scaling factors can be greater than 100%. However, it can be considered that the UE is not allowed to transmit at a transmission power value greater than the maximum transmission power. Therefore, for example, if Furthermore, if the UE uses STxMP to transmit at maximum transmit power on the CCs from both panels, the UE will violate the rule against transmitting at a power higher than the configured maximum transmit power. As will be described in more detail below, the example implementation provides the UE with various ways to perform dynamic power sharing across multiple panels, preventing the UE from transmitting at a power higher than the configured maximum transmit power. However, before describing the examples of dynamic power sharing, it will be explained why the example implementation allows... Configuration.

[0045] As described above, the example implementation involves power sharing among multiple transmitting panels during STxMP. However, because the UE is capable of performing STxMP, it does not mean that the network will configure the UE to use STxMP for every configured UL transmission. Consider the following scenario where the UE can be configured to perform STxMP for CC0 on panels 0 and 1. However, for a specific UL transmission, the network can configure the UE to transmit CC0 only on panel 1. It can also be assumed that power sharing between panels is equal, for example, the scaling factor for panels 0 and 1 is 0.5. In this example, using static power sharing, the UE would be restricted to transmitting CC0 on panel 1 using 0.5x the maximum transmit power, even though CC0 transmission would not occur on panel 0.

[0046] On the other hand, when allowed When configuring, an example configuration could be equal power sharing of more than 50% between panels; for example, the scaling factor for panels 0 and 1 is 0.7. Therefore, in the example at the beginning above, when no CC0 transmission is scheduled on panel 0, the UE will be restricted to transmitting CC0 on panel 1 using 0.7x the maximum transmission power. In this way, more maximum power can be allocated when no transmission is scheduled for another panel. As described above, the configuration for allowing… Dynamic power sharing in STxMP scenarios is adopted when configuring (e.g., scheduling transmission for two panels). Furthermore, when allowing... At this time, the scaling factors do not need to be equal. For example, possible combinations of unequal scaling factors include , ; , ; , ;etc.

[0047] In the third example of the first aspect, This can be configured for a single panel "k" and applied to all active CCs; for example, the maximum transmit power can be used per panel rather than per CC for all CCs, as described above with reference to the first and second examples. This can be represented as for the two panel examples. For panel "k" with CC "f", the scaling factor It can be explicitly indicated via RRC signaling. For example, the scaling factor can be equal to... Alternatively, in some variations, it can operate without any restrictions; for example, the scaling factor can be greater than 1 (or 100%), as described in the second option of the second example above. In examples where the scaling factor is greater than 100%, the example dynamic power sharing described below can be used.

[0048] refer to Figure 4 Example 3 410, each panel has its own maximum transmit power for all CCs transmitted by that panel. Figure 4 In the example, panel #0 402 has a maximum transmit power of 23 dBm and the following scaling factor: Similarly, panel #1 404 has a maximum transmit power of 21 dBm and the following scaling factor: Those skilled in the art can use the described example input parameters and the principles described with respect to Example 2 408 to derive the values ​​shown in Example #3 410.

[0049] In the fourth example of the first aspect, The maximum transmit power can be configured or determined by the UE based on the UE power level. The UE can be defined by a power level. For example, in 5G, there are four (4) defined UE power levels, such as power levels 1 to 4. The example implementation is not limited to four power levels, however, the 5G power levels are used only as examples. It can be seen that, for example, based on each panel, the maximum transmit power of the fourth example is similar to the maximum transmit power of the third example. However, using the fourth example can result in lower signaling overhead because the UE will only need to understand that the maximum transmit power is configured based on the UE power level, and the UE can then apply the maximum transmit power corresponding to the UE power level, for example, the actual maximum transmit power value may not need to be signaled in the configuration.

[0050] Additionally, two scaling factors and It can be explicitly provided via RRC signaling, where Or in some variations, there are no restrictions on operation; for example, the scaling factor can be greater than 100%. In the fourth variation, As can be seen, the scaling factor and With the scaling factor in Example 3 (For example, the scaling factor per CC on each panel) and similar operations.

[0051] In a second aspect of the example implementation, this document discloses power scaling for dynamic power sharing operation for STxMP. As mentioned above, in some examples, it is permissible to configure a scaling factor greater than 100% of the maximum transmit power. However, it may be disallowed for the UE to transmit at a power higher than the maximum transmit power. Therefore, the second aspect describes various examples of dynamic power sharing operation implemented by the UE to ensure that the UE will not transmit at a power higher than the maximum transmit power.

[0052] In the first example of the second aspect, this document discloses a per-panel power scaling operation. The first example is applicable to specific implementations having separate power amplifiers or separate radio frequency (RF) chains for both panels. The power scaling operation of the first example can be represented as follows: For example, the actual maximum transmit power will be less than or equal to the configured maximum transmit power.

[0053] Figure 5 Example method 500 for dynamic power sharing per panel according to various example implementations is shown. Method 500 can describe a first example of the second aspect. As mentioned above, the power scaling operation of the first example is per panel, and therefore applicable to the third and fourth examples of the first aspect described above, for example, the configured maximum transmit power per panel. Therefore, in the example of method 500, the UE can be considered to be utilizing... It's configured.

[0054] In 502, the UE (e.g., UE 110) determines the maximum transmit power for all CCs within the frequency range associated with a single panel "k". For example, used as Figure 4 The maximum transmit power of all CCs on panels 0402 and 1404 shown in Example 3 410.

[0055] In 504, UE 110 determines whether the total uplink transmit power on the CC associated with panel "k" will exceed [the limit]. For example, such as Figure 4 As shown in Example 3 410, the maximum transmit power used for panel 0 402 is 23 dBm. If the sum of the actual transmit power used for the CC associated with panel 0 402 does not exceed the maximum transmit power configured for the panel, then it is not necessary to use... Figure 5 The dynamic power sharing operation is completed, and method 500 ends. However, if the actual transmit power used for the CC associated with panel 0 402 exceeds the maximum transmit power configured for the panel, then... Figure 5 Dynamic power sharing can be used to prevent the UE from transmitting at a power higher than the maximum transmission power configured for the panel. In this example, the maximum transmission power of the panel is considered to have been exceeded, and dynamic power sharing is used. UE 110 can determine this separately for each of the two panels, for example, either neither panel exceeds the maximum transmission power configured for its corresponding panel, only one of the two panels exceeds the maximum transmission power configured for its corresponding panel, or both panels exceed the maximum transmission power configured for their corresponding panels.

[0056] In 506, UE 110 allocates transmission power for uplink transmissions of the Physical Uplink Shared Channel (PUSCH) / Physical Uplink Control Channel (PUCCH), Physical Random Access Channel (PRACH), and Sounding Reference Signal (SRS). The aforementioned transmission allocation ensures that no more than... You can assign a priority index to each sender. Example priority orders can be sorted in descending order as follows:

[0057] • PRACH transmission on the primary cell (PCell).

[0058] • PUCCH or PUSCH transmissions with higher priority indexes.

[0059] • For PUCCH or PUSCH transmissions with the same priority index:

[0060] ○ PUCCH transmission with mixed Automatic Repeat Request (HARQ)-ACK information, and / or Schedule Request (SR), and / or Location Report Request (LRR), or PUSCH transmission with HARQ-ACK information having a priority index.

[0061] ○ PUCCH transmission with Channel State Information (CSI) or PUSCH transmission with CSI.

[0062] ○ PUSCH transmission of HARQ-ACK messages or CSI without priority index, and PUSCH transmission on PCell for Type 2 random access procedures.

[0063] •SRS transmission

[0064] ○ Non-periodic SRS.

[0065] ○ Semi-persistent and / or periodic SRS, or PRACH transmission on a serving cell outside of PCell.

[0066] For example, using the priority order described above, the UE can first allocate transmit power to PRACH transmissions on the PCell. If any remaining transmit power exists at the configured maximum transmit power, the UE can then allocate transmit power to PUCCH or PUSCH transmissions with a higher priority index. This process can continue until the configured maximum transmit power of the panel is reached. Again, if both panels are determined to exceed the configured maximum transmit power, the same dynamic power sharing operation will be applied to the other panel. The priority order described above is merely an example, and other priority orders for uplink transmissions can be used to allocate transmit power.

[0067] In the first example, the determination for power sharing purposes is performed on a per-pane basis, and the power sharing operation on each panel is not affected by the determination of the other panel. For example, if panel 0 402 exceeds its configured maximum transmit power but no transmit is scheduled for panel 1 404, the first example does not allow panel 0 402 to use any transmit power allocated to the unused transmit power of panel 1 404.

[0068] Conversely, in the second example of the second aspect, this document discloses cross-panel dynamic power sharing (CP-DRS) operation. The second example can be applied to... In specific implementations, for example, this example applies where the total UE transmit power used for uplink transmission on the CC associated with two panels will exceed In such scenarios, the UE (e.g., UE 110) prioritizes the transmission power on the CC of the priority panel "i".

[0069] Figure 6 An example method 600 for dynamic power sharing across panels is illustrated according to various example implementations. Method diagram 600 further illustrates a second example of the second aspect.

[0070] In step 602, UE 110 determines whether the actual transmit power used for uplink transmission on the CC associated with the two panels (panel "i" and panel "j") will exceed [the limit]. This will be described if panel "i" is prioritized. Figure 6 The example method is 600, but this can be modified based on the specific implementation, which will be discussed in more detail below. If the actual transmit power does not exceed... Then method 600 is completed and can be used without the example of cross-panel dynamic power sharing.

[0071] If in 604, the actual transmit power exceeds Then UE 110 determines whether the actual transmit power of the serving cell "c" on panel "i" exceeds ,For example, If the actual transmit power of the serving cell "c" on panel "i" exceeds... Then the first dynamic power sharing operation related to the priority panel "i" will be implemented in 606, where UE 110 can apply, for example... Figure 5 The priority sorting list described in operation 506. Therefore, applying the first dynamic power sharing operation will prevent the total UE transmit power of the serving cell on panel "i" used for priority processing from exceeding the limit. .

[0072] After applying the first dynamic power sharing operation in 606, or if in 604, the actual transmit power of the serving cell "c" on panel "i" does not exceed... Method 600 continues to 608, where the second panel "j" (e.g., the panel that was not prioritized) is processed. After 604 or 606, there may be remaining transmit power available for the second panel "j". In 608, UE 110 determines the maximum available remaining upload transmit power for panel "j". .For example, .

[0073] In 610, UE 110 can apply a second dynamic power sharing operation related to the unprioritized panel "j". For example, UE 110 can apply... Figure 5 Operation 506 describes the priority sorting rules in order to allocate the remaining maximum transmit power to panel "j". Therefore, applying the second dynamic power sharing operation will prevent the total transmit power used for all serving cells of panel "j" from exceeding [the limit]. .

[0074] Now returning to operation 602, the logic that can be applied to determine which panel "i" or "j" should be prioritized in the case of power constraints will be described below.

[0075] In the first option for panel selection, RRC signaling can be used to configure either a first panel or a second panel for priority ordering. The first panel may be associated with a first Transmit Configuration Indicator (TCI) state, and the second panel may be associated with a second TCI state.

[0076] In the second option for panel selection, panels associated with the first joint or uplink TCI state can be prioritized for power allocation.

[0077] Figure 7 A diagram 700 illustrating transmit power adjustment according to various example implementation schemes is shown. Figure 7 This could be a second example visualization of the second aspect. In this example, panel "i" will take precedence over panel "j". Furthermore, in... Figure 7 In the example, UE 110 can be considered to be using the maximum uplink transmit power. It was configured using 702. Figure 7 Reference Figure 6 The operation of method 600 is described.

[0078] Initially, there are uplink transmissions scheduled on panel "i", as shown in 712, and uplink transmissions scheduled on panel "j", as shown in 708 and 710. In 602, UE 110 determines whether the actual transmission power of the panel exceeds... 702. In this example, it is shown that the actual transmit power of the two panels does indeed exceed [the limit]. 702, for example > In other words, the total transmit power of uplink transmissions 708, 710, and 712 exceeds [a certain threshold]. 702, which means that UE 110 can apply dynamic power sharing across panels.

[0079] In step 604, UE 110 determines whether the actual transmit power of panel "i" exceeds [the limit]. In this example, the actual transmit power of panel "i" is equal to... Is the actual transmit power based on panel "i" less than or equal to... The determination in 604 is negative. In this example, since the determination is negative, the first dynamic power sharing operation for prioritizing panel "i" in 606 may not be applied; for example, the uplink transmission 712 of panel "i" may be transmitted without any power reduction.

[0080] In 608, UE 110 will determine the remaining maximum transmission power of the configured maximum transmission power that can be used by the second panel "j", for example, .like Figure 7 As shown, this value can be the transmit power of the uplink transmit 712 used for panel "i" and... The difference between 702. However, as Figure 7 As shown, the actual transmit power of uplink transmitters 708 and 710 for panel "j" is greater than... Therefore, the second dynamic power sharing operation of the 610 can be used.

[0081] As described above, the second dynamic power sharing operation of 610 can assign a priority index to each scheduled transmission in the scheduled transmission. Figure 7 In the example, there are two types of scheduled transmissions for panel "j": PUSCH transmission 708 on CC1 and SRS transmission 710 on CC2. In this example, the PUSCH transmission can be considered to have higher priority. Therefore, since there is sufficient remaining power to transmit PUSCH transmission 708 on CC1, these transmissions are transmitted without any power reduction. On the other hand, the power of SRS transmission 710 on CC2 is reduced so that the total transmission power does not exceed the configured power. 702.
