[0001] This application claims priority to U.S. Provisional Application Serial No. 63 / 516,662 filed on July 31, 2023 and entitled, “Panel-Specific Power Control for Multi-Panel Operations,” the entirety of which is incorporated by reference herein. BACKGROUND

[0002] User equipment (UEs) may feature multiple transmit antenna panels such that a UE may be capable of multi-panel transmission, referred to as Simultaneous Multi-Panel (STxMP) transmission. Multi-panel transmission offers enhanced uplink coverage and average throughput for multi-panel UEs. When STxMP transmission is used, the transmission power of the multiple panels is to stay within acceptable transmit power limits. Thus, transmission power sharing between the multiple panels should be defined. In addition, manners of signaling the UE as to how the transmission power should be shared among the panels should also be defined. SUMMARY

[0003] Some example embodiments are related to an apparatus having processing circuitry configured to decode, based on signaling received from a base station, a configured maximum transmission power, wherein the signaling is radio resource control (RRC) signaling and generate, for simultaneous transmission via a first antenna panel and a second antennaAttorney Docket No. 30134 / 83202 Ref. No. P62672WO1 panel, uplink transmissions that do not exceed the configured maximum transmission power.

[0004] Other example embodiments are related to a method that includes receiving a configured maximum transmission power, wherein the signaling is radio resource control (RRC) signaling and simultaneously transmitting, via a first antenna panel and a second antenna panel, uplink transmissions that do not exceed the configured maximum transmission power.

[0012] The example embodiments may be further understood with reference to the following description and the related appended drawings, wherein like elements are provided with the same reference numerals. The example embodiments relate to improved power use for STxMP transmisisons.

[0013] The example embodiments are described with regard to a user equipment (UE). However, reference to a UE is merely provided for illustrative purposes. The example embodiments may be utilized with any electronic component that may establish a connection to a network and is configured with the hardware, software, and / or firmware to exchange information and data with the network. Therefore, the UE as described herein is used to represent any electronic component.

[0014] The example embodiments are also described with reference to a 5G New Radio (NR) network. The example embodiments may also be implemented in other types of networks, including but not limited to LTE networks, future evolutions of the cellular protocol (e.g., 6G networks), or any other type of network.

[0015] Operations and logic are disclosed herein relating to STxMP power reduction. Specifically, the example embodiments relate to logic that accounts for different power amplifier (PA) implementations. The example embodiments cover both panel-Attorney Docket No. 30134 / 83202 Ref. No. P62672WO1 specific maximum power determination logic, as well as panel power scaling logic.

[0016] Fig. 1 shows an example network arrangement 100 according to various example embodiments. The example network arrangement 100 includes a UE 110. The UE 110 may be any type of electronic component that is configured to communicate via a network, e.g., mobile phones, tablet computers, desktop computers, smartphones, phablets, embedded devices, wearables, Internet of Things (IoT) devices (including connected vehicles), etc. An actual network arrangement may include any number of UEs being used by any number of users. Thus, the example of one UE 110 is merely provided for illustrative purposes.

[0017] The UE 110 may be configured to communicate with one or more networks. In the example of the network configuration 100, the network with which the UE 110 may wirelessly communicate is a 5G NR radio access network (RAN) 120. The UE 110 may also communicate with other types of networks (e.g., 5G cloud RAN, a next generation RAN (NG-RAN), a legacy cellular network, etc.) and the UE 110 may also communicate with networks over a wired connection. With regard to the example embodiments, the UE 110 may establish a connection with the 5G NR RAN 120. Therefore, the UE 110 may have a 5G NR chipset to communicate with the NR RAN 120.

[0018] The 5G NR RAN 120 may be portions of a cellular network that may be deployed by a network carrier (e.g., Verizon, AT&T, T-Mobile, etc.). The RAN 120 may include cells or base stations that are configured to send and receive traffic from UEs that are equipped with the appropriate cellular chipAttorney Docket No. 30134 / 83202 Ref. No. P62672WO1 set. In this example, the 5G NR RAN 120 includes the gNB 120A. However, reference to a gNB is merely provided for illustrative purposes, any appropriate base station or cell may be deployed (e.g., Node Bs, eNodeBs, HeNBs, eNBs, gNBs, gNodeBs, macrocells, microcells, small cells, femtocells, etc.).

[0019] Any association procedure may be performed for the UE 110 to connect to the 5G NR RAN 120. For example, as discussed above, the 5G NR RAN 120 may be associated with a particular network carrier where the UE 110 and / or the user thereof has a contract and credential information (e.g., stored on a SIM card). Upon detecting the presence of the 5G NR RAN 120, the UE 110 may transmit the corresponding credential information to associate with the 5G NR RAN 120. More specifically, the UE 110 may associate with a specific cell (e.g., gNB 120A).

[0020] The network arrangement 100 also includes a cellular core network 130, the Internet 140, an IP Multimedia Subsystem (IMS) 150, and a network services backbone 160. The cellular core network 130 manages the traffic that flows between the cellular network and the Internet 140. The IMS 150 may be generally described as an architecture for delivering multimedia services to the UE 110 using the IP protocol. The IMS 150 may communicate with the cellular core network 130 and the Internet 140 to provide the multimedia services to the UE 110. The network services backbone 160 is in communication either directly or indirectly with the Internet 140 and the cellular core network 130. The network services backbone 160 may be generally described as a set of components (e.g., servers, network storage arrangements, etc.) that implement a suite ofAttorney Docket No. 30134 / 83202 Ref. No. P62672WO1 services that may be used to extend the functionalities of the UE 110 in communication with the various networks.

[0021] Fig. 2 shows an example UE 110 according to various example embodiments. The UE 110 will be described with regard to the network arrangement 100 of Fig. 1. The UE 110 may represent any electronic device and may include a processor 205, a memory arrangement 210, a display device 215, an input / output (I / O) device 220, a transceiver 225, and other components 230. The other components 230 may include, for example, an audio input device, an audio output device, a battery that provides a limited power supply, a data acquisition device, ports to electrically connect the UE 110 to other electronic devices, sensors to detect conditions of the UE 110, etc. The other components 230 may also include antenna elements communicatively coupled to the transceiver 225. As will be described in greater detail below, the antenna elements may comprise multiple antenna panels that are located in various positions on or within the UE 110.

[0022] The processor 205 may be configured to execute a plurality of engines for the UE 110. For example, the engines may include an STxMP engine 235 for performing operations related to processing panel specific maximum power determinations, as well as performing panel power scaling operations.

[0023] The above referenced engine being an application (e.g., a program) executed by the processor 205 is only example. The functionality associated with the engines may also be represented as a separate incorporated component of the UE 110Attorney Docket No. 30134 / 83202 Ref. No. P62672WO1 or may be a modular component coupled to the UE 110, e.g., an integrated circuit with or without firmware. For example, the integrated circuit may include input circuitry to receive signals and processing circuitry to process the signals and other information. The engines may also be embodied as one application or separate applications. In addition, in some UEs, the functionality described for the processor 205 is split among two or more processors such as a baseband processor and an applications processor. The example embodiments may be implemented in any of these or other configurations of a UE.

[0024] The memory arrangement 210 may be a hardware component configured to store data related to operations performed by the UE 110. The display device 215 may be a hardware component configured to show data to a user while the I / O device 220 may be a hardware component that enables the user to enter inputs. The display device 215 and the I / O device 220 may be separate components or integrated together such as a touchscreen. The transceiver 225 may be a hardware component configured to establish a connection with the 5G-NR RAN 120. Accordingly, the transceiver 225 may operate on a variety of different frequencies or channels (e.g., set of consecutive frequencies).

[0025] The transceiver 225 includes circuitry configured to transmit and / or receive signals (e.g., control signals, data signals). Such signals may be encoded with information implementing any one of the methods described herein. The processor 205 may be operably coupled to the transceiver 225 and configured to receive from and / or transmit signals to the transceiver 225. The processor 205 may be configured to encode and / or decode signals (e.g., signaling from a base station of aAttorney Docket No. 30134 / 83202 Ref. No. P62672WO1 network) for implementing any one of the methods described herein.

[0026] Fig. 3 shows an example base station 300 according to various example embodiments. The base station 300 may represent the gNB 120A or any other access node through which the UE 110 may establish a connection and manage network operations.

[0027] The base station 300 may include a processor 305, a memory arrangement 310, an input / output (I / O) device 315, a transceiver 320, and other components 325. The other components 325 may include, for example, an audio input device, an audio output device, a battery, a data acquisition device, ports to electrically connect the base station 300 to other electronic devices and / or power sources, etc.

[0028] The processor 305 may be configured to execute a plurality of engines for the base station 300. For example, the engines may include an STxMP engine 330 for performing operations related to transmitting signaling (e.g., via RRC) to the UE 110 to configure panel specific maximum power limits, panel-specific power scaling, and panel prioritization.

[0029] The memory 310 may be a hardware component configured to store data related to operations performed by the base station 300. The I / O device 315 may be a hardware component or ports that enable a user to interact with the base station 300. The transceiver 320 may be a hardware component configured to exchange data with the UE 110 and any other UE in the network arrangement 100. The transceiver 320 may operate on a variety of different frequencies or channels (e.g., set of consecutiveAttorney Docket No. 30134 / 83202 Ref. No. P62672WO1 frequencies). Therefore, the transceiver 320 may include one or more components (e.g., radios) to enable the data exchange with the various networks and UEs.

[0030] The transceiver 320 includes circuitry configured to transmit and / or receive signals (e.g., control signals, data signals). Such signals may be encoded with information implementing any one of the methods described herein. The processor 305 may be operably coupled to the transceiver 320 and configured to receive from and / or transmit signals to the transceiver 320. The processor 305 may be configured to encode and / or decode signals (e.g., signaling from a UE) for implementing any one of the methods described herein.

[0031] In a first aspect of the example embodiments, various manners of determining the maximum transmission power for an antenna panel when STxMP operation is enabled are disclosed. In the following examples, two antenna panels are used. The principles for determining the maximum transmission power for antenna panels as disclosed herein may be extended to the use of more than two antenna panels.

[0032] Fig. 4 shows a panel power diagram 400 related to determining per-panel maximum transmission power for STxMP operation according to various example embodiments. The panel power diagram 400 shows three examples (406, 408, and 410) of the first aspect. The panel power diagram 400 shows a panel #0 402 and a panel #1404. The panels 402 and 404 are used in all three examples 406, 408, and 410 shown in the panel power diagram 400. Additionally, the three shown examples 406, 408, and 410 feature three intra-band component carriers, CC0, CC1,Attorney Docket No. 30134 / 83202 Ref. No. P62672WO1 and CC2 that are configured for each of the panels 402 and 404. One of skill in the art will appreciate that the dBm values shown in Fig. 4 are only examples, and other maximum transmission power values are possible. For example, the configured values of the maximum transmission power may be based on any relevant factor, e.g., regulatory requirements, interference, etc.

[0033] In a first example of the first aspect, two maximum transmission power values (e.g., an individual value for each panel) may be configured by radio resource control (RRC) signaling for each component carrier of a serving cell using ^^^^ ^^ ^^ ^^, ^^, ^^, ^^( ^^ = 0,1) where ‘f’ is a component carrier, ‘c’ is a and ‘k’ is a panel. For example, the panel #0402may be indicated by k=0 and the panel #1404 may be indicated by k=1.

[0034] Returning to the example 1406 in Fig. 4, the power value for each CC of each of the antenna panels 402 and 404 may be explicitly configured by RRC signaling. For example, for CC1 on the Panel #0402, the transmission power may be configured to be 16 dBm. This may be indicated as ^^^^ ^^ ^^ ^^,1,1,0showing that for CC1 on the panel #0402 for serving cell 1, the maximum transmission power may be 16 dBm. Similarly, for CC1 on the Panel #1404, the transmission power may be configured to be 13 dBm. This may be indicated as ^^^^ ^^ ^^ ^^,1,1,1showing that for CC1 on the panel #1404 for serving cell 1, the maximum transmission power may be 13 dBm. One of skill in the art will understand that similar configurations for the remaining CC / panel combinations may also be configured by the network. Thus, in example 1, the networkAttorney Docket No. 30134 / 83202 Ref. No. P62672WO1 configures the maximum transmission power for each panel and signals the values of the maximum transmission power to the UE.

[0035] In a second example of the first aspect, a single value for ^^^^ ^^ ^^ ^^, ^^, ^^may be configured by RRC signaling for carrier ‘f’ of serving cell ‘c’, e.g., a single maximum transmission value for both panels. The signaling of a single maximum transmission power value reduces signaling overhead as compared to the first example where two maximum transmission power values for each CC are signaled. This configuration may introduce two scaling factors, ^^^^, ^^,1and ^^^^, ^^,2, as a ratio of the linear domain value of ^^^^ ^^ ^^ ^^, ^^, ^^. In the second example, ^^^^ ^^ ^^ ^^, ^^, ^^ , ^^= ^^^^ ^^ ^^ ^^, ^^, ^^∗ ^^^^, ^^, ^^, ( ^^ = 0,1). In some variations of the second example, the two factors ^^1and ^^2may be applied to all CCs to allocate the per-CC power PCMAX,f,c.

[0036] All the scaling factors described herein may be used by the UE to determine a maximum transmission power that may be used by the UE (e.g., per panel, per component carrier, etc.) by applying the appropriate scaling factor to a configured maximum transmission power. Various examples of applying the different scaling factors are provided below.

[0037] In a first option of the second example, ^^^^, ^^,1+ ^^^^, ^^,2≤ 100%, including ^^^^, ^^,1= 1 or ^^^^, ^^,2= 1. To elaborateof example, it may be considered that ^^^^, ^^,1+ ^^^^, ^^,2= 100%. In one example, ^^^^, ^^,1= 0.5 or ^^^^, ^^,2= 0.5. In this example, the panels will share transmission power equally, e.g., each panel configured to use up to 50% of the configured maximum transmission power. In another example, ^^^^, ^^,1= 0.7 or ^^^^, ^^,2= 0.3. InAttorney Docket No. 30134 / 83202 Ref. No. P62672WO1 this example, the panels will not share the maximum transmission power equally, e.g., the first panel is configured to use up to 70% of the configured maximum transmission power while the second panel is configured to use up to 30% of the configured maximum transmission power. As can be seen from these examples, when the UE is configured using the first option of the second example, the UE performing STxMP using the two panels will never exceed the configured maximum transmit power.

[0038] The example 2408 of Fig. 4 shows further examples of the first option of the second example. In the example of Fig. 4 for the example 2408, it may be considered that the maximum transmission power value is 21 dBm for CC0 and CC1 and the maximum transmission power value is 18 dBm for CC2, though these values are only examples.

[0039] To determine the dBm values for the CC0, CC1, and CC2 of the example 2408, the following equation may be used: 1 ^^ ^^ ^^ ^^ ^^ ^^ ^^ ^^ ^^ ^^ ^^ ^^ ^^ = ^^ ^^ ^^ ^^ ^^ ^^ ^^ ^^ ^^ ^^ ^^ ^^ ^^ ^^ ^^ − 10 ∗ log10^^ ^^ ^^ ^^ ^^ ^^ ^^ ^^ ^^ ^^ ^^. For example,may be ^^^^ ^^ ^^ ^^, ^^, ^^ , ^^= 21 ; ^^0,0,0= ^^0,0,1= 0.5, e.g., maximum transmission power of 21 dBm and equal scaling factors between each panel (panel #0402 = 0.5 and panel #1404 = 0.5). Using the equation above, 1 ^^ ^^ ^^ ^^ ^^ ^^ ^^ ^^ ^^ ^^ ^^ ^^ ^^ = 21 − 10 ∗ = 17.989 … ≅ 18 ^^ ^^ ^^. Accordingly, both the panel #0402 and#1 404 will have a maximum transmission power value of 18 dBm as shown in Fig. 4.

[0040] Continuing with the example 2408 of Fig. 4, the power scaling values for CC1 may differ from one another, e.g., ^^^^ ^^ ^^ ^^, ^^, ^^ , ^^= 21 ; ^^1,1,0= 0.6 ; ^^1,1,1= 0.4. Using the equation for the CC1Attorney Docket No. 30134 / 83202 Ref. No. P62672WO1 1 of the panel #0402 ^^ ^^ ^^ ^^ ^^ ^^ ^^ ^^ ^^ ^^ ^^ ^^ ^^ = 21 − 10 ∗ log100.6 = 18.781 … ≅ 18.78 ^^ ^^ ^^. Using the #1 404,^^ ^^ ^^ ^^ ^^ ^^ ^^ ^^ ^^ ^^ ^^ ^^ ^^ = 21 − 10 ∗ log100.4 = 17.020 … ≅ 17.02 ^^ ^^ ^^.2 408 of Fig. 4, the power scaling values for CC2 may differ from one another and the ^^^^ ^^ ^^ ^^value may also be different from the ^^^^ ^^ ^^ ^^values of CC0 and CC1, e.g., ^^^^ ^^ ^^ ^^,2,2; ^^2,2,0= 0.2 ; ^^2,2,1= 0.8. Using the equation for 1 CC2 panel #0402, ^^ ^^ ^^ ^^ ^^ ^^ ^^ ^^ ^^ ^^ ^^ ^^ ^^ = 18 − 10 ∗ log100.2 = 11.010 … ≅ 11 ^^ ^^ ^^. Using the ^^ ^^ ^^ ^^ ^^ ^^ ^^ = 18 − 10 ∗1 log10= 17.030 … ≅ 17.03 ^^ ^^ ^^. One of skill in the art will 0.2 appreciate that any rounding scheme of a newly determined maximum transmission power for STxMP value is left to operator implementation. Additionally, using different values for the different parameters (e.g., maximum transmission power, scaling factor) for each CC is only an example. For example, all CCs may have the same maximum transmission power and scaling factors.

[0042] In a second option of the second example, the scaling factors may operate without limitation, for example ^^^^, ^^,1+ ^^^^, ^^,2≤ 100% or ^^^^, ^^,1+ ^^^^, ^^,2> 100%. Where the scalingto or less than 100%, this option may be considered to be similar to the first option of the second example as described above and will not be described further.

[0043] In the second option of the second example, the sum of the scaling factors may be greater than 100%. However, it may be considered that the UE is not allowed to transmit at a transmission power value that is greater than the maximumAttorney Docket No. 30134 / 83202 Ref. No. P62672WO1 transmission power. Thus, for example, if ^^^^, ^^,1+ ^^^^, ^^,2= 120% and the UE uses STxMP to transmit on a CC from both panels at the maximum transmission power, the UE wouldthe rule of not transmitting above the configured maximum transmission power. As will be described in greater detail below, the example embodiments provide various manners for the UE to perform dynamic power sharing across multiple panels that prevent the UE from transmitting above the configured maximum transmission power. However, prior to describing the examples of dynamic power sharing, it will be described as to why the example embodiments allow a configuration of ^^^^, ^^,1+ ^^^^, ^^,2> 100%.

[0044] As described above, the example embodiments are concerned with sharing power among multiple transmission panels during STxMP. However, because a UE is capable of performing STxMP, does not mean the network will configure the UE to use STxMP for every configured UL transmission. Consider the following scenario, the UE may be configured to perform STxMP for CC0 on panels 0 and 1. However, for a particular UL transmission, the network may configure the UE to only transmit CC0 on panel 1. It may also be considered that the power sharing between the panels is equal, e.g., the scaling factor for panel 0 and panel 1 is 0.5. In this example, using a static power sharing technique, the UE would be limited to transmitting the CC0 on panel 1 using 0.5 x maximum transmission power, even though there will be no CC0 transmission on panel 0.

[0045] On the other hand, when a configuration of ^^^^, ^^,1+ ^^^^, ^^,2> 100% is allowed, an example configuration may be equal power sharing between panels that is greater than 50%, e.g., the scaling factor for panel 0 and panel 1 is 0.7. Thus, in theAttorney Docket No. 30134 / 83202 Ref. No. P62672WO1 example started above, when there is no CC0 transmission on panel 0, the UE would be limited to transmitting the CC0 on panel 1 using 0.7 x maximum transmission power. In this way, more of the maximum power may be allocated when there is no transmission scheduled for the other panel. As stated above, dynamic power sharing for the scenario where STxMP is employed when the configuration of ^^^^, ^^,1+ ^^^^, ^^,2> 100% is allowed, e.g., there are transmission scheduled for both panels, is described in greater detail below. In addition, when ^^^^, ^^,1+ ^^^^, ^^,2> 100% is allowed, the scaling factors do not need equal. Forexample, possible unequal scaling factor combinations include, ^^^^, ^^,1= 0.7, ^^^^, ^^,2= 0.4; ^^^^, ^^,1= 0.7, ^^^^, ^^,2= 0.6; ^^^^, ^^,1= 0.6, ^^^^, ^^,2= 0.8; etc.

[0046] In a third example of the first aspect, a ^^^^ ^^ ^^ ^^, ^^may be configured for a single panel ‘k’ and applied for all active CCs, e.g., the maximum transmission power is for all CCs on a per panel basis rather than on a per CC basis as was described above with reference to the first and second examples. This may be expressed as ^^^^ ^^ ^^ ^^, ^^(^^ = 0,1)for the two panel example. For a CC ‘f’, of a panel ‘k’, a scaling factor ^^^^, ^^may be explicitly indicated via RRC signaling. For example, the scaling factor may be equal to∑∞ ^^=1^^^^, ^^≤ 1, or in some variants, operate without anyscaling factor may be greater than 1 (or 100%) as described in the second option of the second example above. In the examples where the scaling factor is greater than 100%, the example dynamic power sharing described below may be used.

[0047] Referring to example 3410 of Fig. 4, each panel has its own maximum transmission power to use for all CCsAttorney Docket No. 30134 / 83202 Ref. No. P62672WO1 transmitted by that panel. In the example of Fig. 4, the panel #0 402 has a maximum transmission power of 23 dBm and scaling factors as follows: ^^^^ ^^ ^^ ^^,0= 23; ^^0,0,0= 0.5; ^^1,1,0= 0.3; ^^2,2,0= 0.2. Similarly, the panel #1404 has a maximum transmission power of 21 dBm and scaling factors as follows: ^^^^ ^^ ^^ ^^,1= 21; ^^0,0,1= 0.6; ^^1,1,1= 0.2; ^^2,2,1= 0.2. One of skill in the art may derive the values shown in the example #3410 with the described example input parameters and the principles described with respect to the example 2408.

[0048] In a fourth example of the first aspect, a ^^^^ ^^ ^^ ^^, ^^( ^^ = 0,1) may be configured or determined by a UE based on a UE power class. UEs may be defined by power class. For example, in 5G there are four (4) defined UE power classes, e.g., Power Class 1-4. The example embodiments are not limited to four power classes but the 5G power classes are only being used as examples. It can be seen that the maximum transmission power for the fourth example is similar to the maximum transmission power for the third example, e.g., on a per panel basis. However, using the fourth example may result in lower signaling overhead because the UE would only need to understand that the maximum transmission power is being configured based on UE power class and the UE may then apply the maximum transmission power corresponding to the UE power class, e.g., the actual maximum transmission power values may not need to be signaled in the configuration.

[0049] Additionally, two scaling factors, ^^1and ^^2may be explicitly provided via RRC signaling,1, or in some variants, operate without anytheAttorney Docket No. 30134 / 83202 Ref. No. P62672WO1 scaling factors may be greater than 100%. In the fourth variant, ^^^^ ^^ ^^ ^^, ^^= ^^^^ ^^ ^^ ^^, ^^∗ ^^^^(^^ = 0,1). As can be seen, the scaling factors, ^^1and ^^2operate in a similar manner as the scaling factor ^^^^, ^^in3, e.g., a scaling factor per CC on each panel.

[0050] In a second aspect of the example embodiments, power scaling for dynamic power sharing operations for STxMP is disclosed herein. As described above, in some examples, configuration of scaling factors that are more than 100% of the maximum transmission power may be allowed. However, the UE may not be allowed to transmit above the maximum transmission power. Thus, the second aspect will describe various examples of UE implemented dynamic power sharing operations to assure that the UE will not transmit above the maximum transmission power.

[0051] In a first example of the second aspect, per panel power scaling operations are disclosed herein. The first example may be applicable for implementations featuring separate power amplifiers or separate radio frequency (RF) chains for the two panels. The power scaling operations of the first example may be expressed as follows: ∑ 2 ^^=1^^^^ ^^ ^^ ^^, ^^≤ ^^^^ ^^ ^^ ^^, e.g., the actual maximum transmission powerthan or equal to the configured maximum transmission power.

[0052] Fig. 5 shows an example method 500 for per panel dynamic power sharing according to various example embodiments. The method 500 may describe the first example of the second aspect. As described above, the power scaling operations of the first example are on a per panel basis and therefore may be applicable to the third and fourth examples of the first aspect described above, e.g., the configured per panel maximumAttorney Docket No. 30134 / 83202 Ref. No. P62672WO1 transmission power. Thus, in the example of the method 500, it may be considered that the UE is configured with ^^^^ ^^ ^^ ^^, ^^(^^ = 0,1).

[0053] In 502, the UE (e.g., the UE 110) determines a maximum transmission power ^^^^ ^^ ^^ ^^, ^^for all CCs in a frequency range associated with a single panel, ‘k’, e.g., the maximum transmission power for all CCs on panel 0402 and panel 1404 as shown in example 3410 of Fig. 4.

[0054] In 504, the UE 110 determines whether the total uplink transmission power on the CCs associated with panel ‘k’ would exceed ^^^^ ^^ ^^ ^^, ^^. For example, as shown in example 3410 of Fig. 4, the maximum transmission power for panel 0402 is 23 dBm. If the sum of the actual transmission power for the CCs associated with panel 0402 does not exceed the configured maximum transmission power for the panel, the dynamic power sharing operations of Fig. 5 may not be used and the method 500 ends. However, if the actual transmission power for the CCs associated with panel 0 402 exceeds the configured maximum transmission power for the panel, the dynamic power sharing operations of Fig. 5 may be used to prevent the UE from transmitting above the configured maximum transmission power for the panel. In this example, it may be considered that the maximum transmission power for the panel is exceeded and the dynamic power sharing operations are used. The UE 110 may make the determination for both panels independently, e.g., both panels do not exceed the configured maximum transmission power for the corresponding panel, only 1 of the 2 panels exceeds the corresponding configured maximum transmission power or both panels exceed the configured maximum transmission power for the corresponding panel.Attorney Docket No. 30134 / 83202 Ref. No. P62672WO1

[0055] In 506, the UE 110 allocates transmit power for uplink transmissions of Physical Uplink Shared Channel (PUSCH) / Physical Uplink Control Channel (PUCCH), Physical Random Access Channel (PRACH), and Sounding Reference Signal (SRS). The allocation of the aforementioned transmissions is such that ^^^^ ^^ ^^ ^^, ^^is not exceeded. The transmissions may each be assigned a priority index. An example priority order may be as follows, in descending order: • PRACH transmission on the Primary Cell (PCell). • PUCCH or PUSCH transmissions with a greater priority index. • For PUCCH or PUSCH transmissions with the same priority index: o PUCCH transmission with Hybrid Automatic Repeat Request (HARQ)-ACK information, and / or a scheduling request (SR), and / or a Location Report Request (LRR), or a PUSCH transmission with HARQ-ACK information of the priority index. o PUCCH transmission with channel state information (CSI) or PUSCH transmission with CSI. o PUSCH transmission without HARQ-ACK information of the priority index or CSI and for Type-2 random access procedure, PUSCH transmission on the PCell • SRS transmission o Aperiodic SRS. o Semi-persistent and / or periodic SRS, or PRACH transmission on a serving cell other than the PCell.

[0056] For example, using the above priority order, the UE may first allocate transmission power to a PRACH transmission on the PCell. If there is any remaining transmission power of theAttorney Docket No. 30134 / 83202 Ref. No. P62672WO1 configured maximum transmission power, the UE may then allocate transmission power to PUCCH or PUSCH transmissions with a greater priority index. This process may continue until the configured maximum transmission power for the panel is reached. Again, if both panels are determined to exceed the configured maximum transmission power, the same dynamic power sharing operations will be applied to the other panel. The priority order described above is only an example and other priority orders for uplink transmissions may be used to allocate transmission power.

[0057] In the first example, the determinations for the purposes of power sharing are made on a per panel basis and the power sharing operations on each panel are not affected by the determinations of the other panel. For example, if the panel 0 402 exceeded the configured maximum transmission power but there were no transmissions scheduled for the panel 1404, the first example does not allow for the panel 0402 to use any of the transmission power that was allocated to the unused panel 1404.

[0058] In contrast, in a second example of the second aspect, cross-panel dynamic power sharing (CP-DRS) operations are disclosed herein. The second example may be applicable for implementations where∑1 ^^=0^^^^ ^^ ^^ ^^, ^^> ^^^^ ^^ ^^ ^^, e.g., this example is applicable to scenarios in which the total UE transmit power for uplink transmissions on CCs associated with two panels would exceed ^^^^ ^^ ^^ ^^. In such a scenario, a UE (e.g., the UE 110) prioritizes transmission power on CCs of a prioritized panel ‘i'.Attorney Docket No. 30134 / 83202 Ref. No. P62672WO1

[0059] Fig. 6 shows an example method 600 for cross panel dynamic power sharing according to various example embodiments. The method diagram 600 may further describe the second example of the second aspect.

[0060] In 602, the UE 110 determines whether the actual transmission power for uplink transmission on CCs associated with two panels, a panel ‘i', and a panel ‘j’, would exceed ^^^^ ^^ ^^ ^^. The example method 600 of Fig. 6 will be described with prioritization of panel ‘i', but this may change based on implementation, which will be discussed in greater detail below. If the actual transmission power does not exceed ^^^^ ^^ ^^ ^^, the method 600 is complete and the example cross panel dynamic power sharing may not be used.

[0061] If the actual transmission power exceeds ^^^^ ^^ ^^ ^^, in 604, the UE 110 determines whether the actual transmission power of a serving cell ‘c’ on panel ‘i' exceeds ^^^^ ^^ ^^ ^^, ^^, e.g., ∑ ^^^^, ^^> ^^^^ ^^ ^^ ^^, ^^. If the actual transmissionpower of a serving cell ‘c’ on panel ‘i' exceeds ^^^^ ^^ ^^ ^^, ^^, a first dynamic power sharing operation related to the prioritized panel “i” will be implemented in 606 where the UE 110 may apply, for example, the prioritization list described in Fig. 5, the operation 506. Thus, applying the first dynamic power sharing operation will prevent the total UE transmission power for a serving cell on the prioritized panel ‘i’ from exceeding ^^^^ ^^ ^^ ^^, ^^.

[0062] After applying the first dynamic power sharing operation in 606 or if the actual transmission power of a serving cell ‘c’ on panel ‘i' does not exceed ^^^^ ^^ ^^ ^^, ^^in 604, theAttorney Docket No. 30134 / 83202 Ref. No. P62672WO1 method 600 continues to 608 where the second panel “j” (e.g., the non-prioritized panel) is handled. After 604 or 606, there may be remaining transmission power that may be used by the second panel “j”. In 608, the UE 110 determines an available remaining upload maximum transmission power for panel ‘j’, ^^ ^^ ^^ ^^ ^^ ^^, ^^. For example, ^^^^^^^^ ^^ ^^, ^^= ^^^^ ^^ ^^ ^^− min (∑ ^^^^, ^^, ^^^^ ^^ ^^ ^^, ^^).

[0063] In 610, may a dynamic power sharing operation related to the non-prioritized panel “j”. For example, the UE 110 may apply the prioritization rule described in Fig. 5, the operation 506, to allocate the remaining maximum transmission power for panel ‘j’, ^^ ^^ ^^ ^^ ^^ ^^, ^^. Thus, applying the second dynamic power sharing operation will prevent the total transmission power on all serving cells for the panel ‘j’ from exceeding ^^ ^^ ^^ ^^ ^^ ^^, ^^.

[0064] Returning now to the operation 602, the following will describe logic that nay be applied to determine which panel, ‘i' or ‘j’ to prioritize in the case of power limitation.

[0065] In a first option for panel selection, RRC signaling may be used to configure the first panel or the second panel for prioritization. The first panel may be associated with a first Transmission Configuration Indicator (TCI) state and the second panel may be associated with a second TCI state.

[0066] In a second option for panel selection, the panel associated with a first joint or uplink TCI state may be prioritized for power allocation.Attorney Docket No. 30134 / 83202 Ref. No. P62672WO1

[0067] Fig. 7 shows a transmit power adjustment diagram 700 according to various example embodiments. Fig. 7 may be an example visualization of the second example of the second aspect. In this example, the panel ‘i' will be prioritized over panel ‘j’. Also, in the example of Fig. 7, it may be considered that the UE 110 is configured with a maximum uplink transmission power ^^^^ ^^ ^^ ^^702. Fig. 7 will be described with reference to the operations of the method 600 of Fig. 6.

[0068] Initially, there are uplink transmissions scheduled on panel ‘i', shown in 712, and uplink transmissions scheduled on panel ‘j', shown in 708 and 710. In 602, the UE 110 determines whether the actual transmission power for the panels exceed the ^^^^ ^^ ^^ ^^702. In this example, it is shown that the actual transmission power for the two panels does exceed the ^^^^ ^^ ^^ ^^702, e.g., ^^^^ ^^ ^^ ^^, ^^ 704 + ^^^^ ^^ ^^ ^^, ^^706 > ^^^^ ^^ ^^ ^^702. That is, the sum of the transmission power for uplink transmissions 708, 710 and 712 exceed the ^^^^ ^^ ^^ ^^702 meaning that the UE 110 may apply dynamic power sharing across the panels.

[0069] In 604, the UE 110 determines whether the actual transmission power of panel ‘i' exceeds the ^^^^ ^^ ^^ ^^, ^^. In this example, the actual transmission power of panelis equal to the ^^^^ ^^ ^^ ^^, ^^. The determination of 604 is negative based on whether the actual transmission power of panel ‘i' is less than or equal to the ^^^^ ^^ ^^ ^^, ^^. In this example, since the determination is negative, the first dynamic power sharing operation for the prioritized panel ‘i’ in 606 may not be applied, e.g., the uplink transmissions 712 of panel ‘i’ may be sent without any reduction in power.Attorney Docket No. 30134 / 83202 Ref. No. P62672WO1

[0070] In 608, the UE 110 will determine the remainder of the configured maximum transmission power that can be used by the second pane; ‘j’, e.g., ^^^^^^^^ ^^ ^^, ^^= ^^^^ ^^ ^^ ^^− min (∑^^^^, ^^, ^^^^ ^^ ^^ ^^, ^^). As shown in Fig. 7, this valuetransmission power used of panel ‘i’ and the ^^^^ ^^ ^^ ^^702. However, as shown in Fig. 7, the actual transmission power for the uplink transmissions 708 and 710 for the panel ‘j’ are greater than the ^^ ^^ ^^ ^^ ^^ ^^, ^^. Thus, the second dynamic power sharing operation of 610 may be used.

[0071] As described above, the second dynamic power sharing operation of 610 may assign a priority index to each of the scheduled transmissions. In the example of Fig. 7, there are two types of scheduled transmissions for the panel ‘j’, PUSCH transmissions 708 on CC1 and SRS transmissions 710 on CC2. In this example, it may be considered that the PUSCH transmissions have a higher priority. Thus, since there is enough power remaining to transmit the PUSCH transmissions 708 on CC1, these transmissions are sent without any reduction in power. On the other hand, the SRS transmissions 710 on CC2 are reduced in power such that the total transmission power does not exceed the configured ^^^^ ^^ ^^ ^^702. Examples
