[0024] It will be readily understood that the components of certain example embodiments as generally described and illustrated in the figures herein may be arranged and designed in a wide variety of different configurations. The following is a detailed description of some example embodiments of systems, methods, apparatus, and computer program products for enhanced operation for transmit power operation.

[0025] The features, structures, or characteristics of the example embodiments described throughout this specification may be combined in any suitable manner in one or more example embodiments. For example, the use of the phrases "certain embodiments," "example embodiments," "some embodiments," or other similar language throughout this specification refers to the fact that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment. Thus, the appearance of the phrases "in certain embodiments," "example embodiments," "in some embodiments," "in other embodiments," or other similar language throughout this specification does not necessarily refer to the same set of embodiments, and the described features, structures, or characteristics may be combined in any suitable manner in one or more example embodiments. Furthermore, the terms "base station," "cell," "node," "gNB," "network," or other similar language may be used interchangeably throughout this specification.

[0026] As used herein, “at least one of: ” and “at least one of ” and similar expressions mean at least any one of the elements, or at least any two or more of the elements, or at least all of the elements, where the list of two or more elements is connected by “and” or “or”.

[0027] New Radio (NR) physical uplink shared channel (PUSCH) power control can be based on a combination of open-loop power control and closed-loop power control. Open-loop power control can include support for fractional path loss compensation, where the user equipment (UE) estimates the uplink (UL) path loss based on downlink (DL) measurements and sets the transmit power accordingly. On the other hand, closed-loop power control can be based on explicit transmit power control (TPC) commands provided by the network.

[0028] As in the Third Generation Partnership Project (3 rdAs described in the specifications of the 3rd Generation Partnership Project (3GPP), the UE can determine the PUSCH transmission power. For example, the UE can indicate / determine closed-loop parameters (e.g., closed-loop index and / or TCP command) and open-loop parameters (e.g., path loss reference RS, p0 and / or alpha). The TCP command can be carried in the downlink control information (DCI) that schedules the PUSCH transmission. The TPC command (and the corresponding closed-loop index) can also be jointly carried to multiple UEs using group-shared DCI using DCI format 2-2.

[0029] The PUSCH transmission power may depend on certain power control parameters. These power control parameters may include, for example, a closed loop index (e.g., PC adjustment state), a TPC command (f b,f,c , absolute or cumulative TPC command), path loss reference signal (RS), p0 (also denoted as P 0_UE_PUSCH ), alpha (for partial full path loss compensation) and / or DELTA_TF (i.e., Δ TF,b,f,c (i)), sometimes also called the power adjustment component. DELTA_TF can model how the required received power changes when the number of information bits per resource element (BPRE) changes due to different modulation schemes and channel coding rates.

[0030] If the UE uses the parameter set configuration with index j and the PUSCH power control adjustment with index l to transmit PUSCH on the bandwidth part (BWP) b of the active UL of carrier f of serving cell c, the transmission power P of the PUSCH in PUSCH transmission opportunity i can be determined PUSCH,b,f,c (i, j, qd, l). For example, the UE may determine the transmission power P of the PUSCH in the PUSCH transmission opportunity i as follows PUSCH,b,f,c (i,j,qd,l):

[0031] Sounding Reference Signal (SRS) power control can be similar to PUSCH power control. For example, the SRS transmission power can be determined based on the SRS transmission time when the UE uses the SRS power control adjustment state with index l, based on the configuration of the SRS-ResourceSet, on the active UL bandwidth part (BWP) b of the carrier f of the serving cell c. For example, the UE can determine the SRS transmission power P in the SRS transmission opportunity i as follows SRS,b,f,c (i,as,l):

[0032] The physical uplink control channel (PUCCH) transmission power may be determined when the UE transmits a PUCCH on an active UL BWP b of a carrier f of a primary cell c using the PUCCH power control adjustment state with index 1. For example, the UE may determine the PUCCH transmission power P in a PUCCH transmission opportunity i as follows: PUCCH,b,f,c (i,qu,qd,l):

[0033] The transmit power reduction may be prioritized. For example, the prioritization procedure for transmit power reduction may involve parallel UL transmissions on different (serving) cells, such as in the case of carrier aggregation (CA) or dual connectivity. For single cell operation with two UL carriers or operation with CA, if the total UE transmit power of PUSCH, PUCCH, Physical Random Access Channel (PRACH) or SRS transmissions on the serving cell exceeds 1 in the frequency range in the corresponding transmission opportunity i, the UE may prioritize transmit power reduction. (in is the P in transmission opportunity i for FR1 and for FR2 CMAX (i) linear value), the UE allocates power to PUSCH / PUCCH / PRACH / SRS transmissions according to the priority order (e.g., descending order). This is done so that the total transmit power of the UE transmitting on the serving cell in the frequency range is less than or equal to the power of the frequency range in each symbol of the transmission opportunity i. For power allocation purposes, if UCI-MuxWithDifferPriority is provided to a UE and the UE multiplexes automatic repeat request-acknowledgement (HARQ-ACK) information in the PUSCH, the priority index of the PUSCH is the larger of: (a) the priority index of the PUSCH before the HARQ-ACK information is multiplexed, and (b) the larger priority index of the HARQ-ACK information. When determining the total transmit power of the serving cell in the frequency range of the transmission opportunity of symbol i, the UE does not include the power for transmissions starting after the transmission opportunity of symbol i. In addition, the total UE transmit power in a symbol of a time slot can be defined as the sum of the linear values of the UE transmit power of PUSCH, PUCCH, PRACH, and SRS in the symbols of the time slot.

[0034] When the priority order is the same, and for operation with carrier aggregation, the UE may prioritize allocating power to transmissions on the primary cell (PCell) or secondary cell group (SCG) of the primary cell group (MCG) over transmissions on the secondary cell (SCell). When the priority order is the same, and for operation with two UL carriers, the UE may prioritize allocating power to transmissions on the carrier on which the UE is configured to transmit PUCCH. If PUCCH is not configured for either UL carrier, the UE may prioritize allocating power to transmissions on the non-supplementary UL carrier.

[0035] LTE and NR support a power headroom (PHR) medium access control element (MAC CE), which contains the nominal UE maximum transmit power and the power headroom for the transmission containing the PHR report. The PHR is the difference between the nominal UE maximum transmit power and the estimated power (in the above equation). The PHR report may also include (1) a P-bit, which is an indication of power backoff due to power management, and (2) a maximum permitted exposure (MPE) value, which is the amount of power backoff to meet the MPE requirement.

[0036] The P-bit and MPE (P-MPR) value can also be used to meet power exposure requirements. P-MPRc is a power management maximum power reduction that ensures compliance with applicable electromagnetic energy absorption requirements and addresses unwanted emission / self-defense requirements in the case of simultaneous transmission of multiple radio access technologies (RATs) for scenarios that are not within the scope of the 3GPP RAN specifications. P-MPRc can also be a power management maximum power reduction that ensures compliance with applicable electromagnetic energy absorption requirements in proximity detection situations to meet requirements that require lower maximum output power.

[0037] In some cases, when the UE is power limited due to overlapping UL transmissions (e.g., PUCCH / PUSCH / SRS / PRACH) in, for example, carrier aggregation or dual connectivity (i.e., a UE connected to two radio access technologies such as 5G and 6G), and more generally in case of overlapping / parallel UL transmissions on the same component carrier (CC) or different CC / UL / bandwidth, the UE may perform or apply one or more UL transmissions. For example, one example UL transmission may include first scaling down the power or applying drops to the lowest priority until the aggregate power is within the configured maximum transmit / output power (Pcmax) and specifically within the total configured maximum output power (denoted as Pcmax). CMAXAnother example UL transmission may include scaling or dropping all or part of the transmission, which may be left to the UE to implement. Therefore, when there is Tx power reduction, SRS, PUCCH, and / or PUSCH may be affected due to power reduction or (complete / partial) dropping. This may negatively impact UE performance in the UL or DL due to the impact on CSI / HARQ-ACK reporting.

[0038] In some cases, the gNB may not be aware that a UE has been dropped and / or (significantly) reduced in Tx power due to power reduction priority or power-limited applications. The gNB may also not suspect that such an event has occurred at the UE. However, such an assumption requires time (e.g., not instant knowledge) and would need to be based on some detection algorithm. Nevertheless, this assumption is only a guess by the gNB.

[0039] In view of the above shortcomings, certain example embodiments may provide a way to reflect the power reduction priority (dropping or significant power reduction) due to overlapping / parallel (or simultaneous) UL transmissions. For example, Figure 1 An example overlap of UL transmission and required Tx power is shown. Figure 1 As shown, UE Pcmax covers the entire Tx power of UL transmissions in PCell, while only a portion of the Tx power of UL transmissions in SCell is covered. That is, the UE in this example is applying power reduction due to the overlapping UL transmissions in PCell and SCell. On the other hand, Figure 2 Another example overlap of UL transmission and required Tx power is shown. Figure 2 As shown, UE Pcmax covers the entire Tx power of UL transmissions in PCell and SCell#1, but no UE power is shown in SCell#2. Therefore, the UE applies the discarding of UL transmissions from SCell#2. Figure 1 and 2 In this example, the gNB is unaware of power reductions and drops. Furthermore, overlapping / parallel UL transmissions can occur across CCs / s / cells or carriers or cell groups or across bandwidths (or bandwidth fractions) or within the same cell. As previously mentioned, even if the gNB could guess / estimate power reductions and / or drops, the process would be time-consuming and highly inefficient. This includes situations where there is loose or no coordination between the network entities receiving transmissions, including inter-band CA, dual connectivity or multi-RAT, and multiple Transmit Reception Points (TRPs) (with non-ideal backhaul between TRPs).

[0040] Figure 3 shows examples of dropping / blanking according to certain example embodiments, and Figure 4 An example of power reduction according to certain example embodiments is shown. Figure 3 As shown in FIG, due to power reduction priority (e.g., when there are overlapping / parallel UL transmissions), the UL transmission on SCell#2 is dropped, which causes the UE to send an indication to the gNB. Figure 4 As shown, due to power reduction prioritization (e.g., when there are overlapping / parallel UL transmissions), the UE may perform a significant power reduction (e.g., 6 dB or greater) at the SCell, which causes the UE to send an indication to the gNB. Given the UE's power limitations due to overlapping / parallel UL transmissions, the UE of certain example embodiments may provide an indication to the gNB. In some example embodiments, this indication may include information indicating that the UE is applying dropping / blanking due to power reduction prioritization and / or that the UE is power limited due to overlapping / parallel UL transmissions. For example, the UE may be / will be power limited when the total power limit is (or will be) reached or when the per-cell power limit is reached. However, in some cases, power limitation may occur regardless of the presence of simultaneous transmissions. Additionally, if, during simultaneous transmissions, the per-cell power limit is reached without reaching the configured per-cell power, one or more cells may reduce their power (or blank their transmissions) to still fit within the total power constraint. In this case, the power reduction prioritization may correspond to a rule that orders the Tx power reduction of each cell among the cells during simultaneous transmissions.

[0041] In certain example embodiments, the information may alternatively indicate that the UE is applying (significant) Tx power reduction. For example, because the power reduction priority for the UE is power-limited, the application of significant Tx power reduction may be defined as a power reduction that is greater than a threshold or causes the Tx power to fall below a threshold defined by the gNB and communicated to the UE (e.g., via a radio resource control (RRC) message). In other example embodiments, another indication may be provided from the UE to the gNB to indicate that the UE has not applied a drop due to the power reduction priority. Alternatively or additionally, the UE may indicate that the UE has not applied (significant) Tx power reduction due to the power reduction priority.

[0042] According to certain example embodiments, an indication may be sent from the UE to the gNB and may be per CC or cell group, per bandwidth portion or bandwidth, per panel, per capability set index, per control resource set pool index (CORESETPoolIndex), per reference signal set, or per TRP. According to some example embodiments, the indication may include an index or identification (or ID) of one or more entries / entities. An entry / entity may include, for example, a CC / cell, cell group, bandwidth (or bandwidth portion), CORESET pool, panel ID, per capability set index, TRP, remote radio head (RRH), node, and / or UL / DL reference signal resource set. In some example embodiments, the index or identification (or ID) may be indicated if the UE applies dropping and / or (significant) Tx power reduction to the corresponding entry / entity. Alternatively or additionally, any of the above indices or identifications (e.g., IDs) may be indicated if the UE does not apply dropping and / or (significant) Tx power reduction on / in the corresponding entry / entity.

[0043] In certain example embodiments, the indication may include an identification of which UL signal / channel the information corresponds to or is associated with. Additionally, the indication may be sent by the UE to the gNB via at least one UL resource (e.g., PUCCH and PUSCH) on a cell / cell group on which a drop and / or (significant) Tx power reduction due to power prioritization has occurred. Alternatively, in other example embodiments, the indication may be sent on at least one UL resource corresponding to at least one dedicated configured cell, cell group, or link.

[0044] According to other example embodiments, the indication may be carried by uplink control information (UCI) on the PUCCH or UCI piggybacked or multiplexed on the PUSCH. For example, the UE may be configured to send / multiplex UCI on the PUCCH / PUSCH (or any other channel or signal) of the PCell. The PUCCH / PUSCH (or any other UL channel or signal) may be part of an overlapping UL transmission, or it may be a separate transmission (or a later transmission). In other example embodiments, the UE may also be configured to send / multiplex UCI on the PUCCH / PUSCH (or any other UL channel or signal) of the SCell if a drop and / or (significant) Tx power reduction has occurred on the PUCCH / PUSCH (or any other UL channel or signal) on the SCell due to power priority, and the corresponding resulting Tx power is above a threshold, or the power reduction is less than an offset. The PUCCH / PUSCH may also be part of an overlapping UL transmission, or it may be a transmission (or a later transmission).

[0045] In certain example embodiments, the UE may be configured to provide an indication in at least one overlapping UL transmission. The UE may also be configured to provide the indication after a predetermined time period from the overlapping transmission (e.g., from the first or last symbol of the transmission overlapping, or from the UL transmissions that overlap in time). In some example embodiments, the predetermined time period may be set by the gNB and communicated to the UE. Alternatively or additionally to UCI, the UE may send the indication via a MAC CE over UL resources of the PCell or SCell. By replacing UCI with a MAC CE, the example embodiments described herein for UCI may also be applicable to MAC CEs.

[0046] According to certain example embodiments, the UE may indicate to the network (e.g., gNB) that the indication is carried in an UL channel / signal. This may be accomplished using at least one bit via UCI or MAC CE or using a UE-selected reference signal (such as a dedicated demodulation reference signal (DMRS) configuration / sequence, etc.). Alternatively, the UE may indicate to the network via UL resource selection. For example, the UE may select and / or transmit dedicated UL resources (e.g., scheduling request-type resources), and the network will then be aware, based on the selection / transmission, that an indication or a portion of an indication is being transmitted or needs to be transmitted.

[0047] In some example embodiments, the indication sent from the UE to the network may be carried via dedicated / shared periodic UL resources, semi-persistent UL resources, or scheduling request-type resources (or resource configurations). These resources may be configured per cell, per cell group, per TRP, or per bandwidth. The UE may also indicate to the network that the discarding of UL transmissions corresponds to partial or complete discarding. The UE may further indicate to the network the number of transmissions, cells, or links to which the UE has applied discarding and / or (significant) Tx power reduction.

[0048] Figure 5 An example signal diagram according to certain example embodiments is shown. At 515, the UE 500 is configured by the network to provide an indication to the network that the UE discards / blanks the transmission due to power reduction priority when there are overlapping UL transmissions from the UE 500. At 520, the UE 500 determines that there are overlapping UL transmissions and that the UE 500 may discard the UL transmission on the Scell 510 due to power reduction priority (i.e., because the UE is power limited). At 525, the UE 500 sends an indication to the network via the PCell to discard / blank the UL transmission on the SCell. Alternatively, in other example embodiments, at 530, the UE 500 sends an indication to the network via the SCell to discard / blank the UL transmission on the PCell.

[0073] In some example embodiments, an apparatus (e.g., apparatus 10 and / or apparatus 20) may include a module for performing a method, process, or any variant discussed herein. Examples of the apparatus may include one or more processors, memories, controllers, transmitters, receivers, and / or computer program codes for causing the execution of operations.

[0074] Certain example embodiments may be directed to an apparatus comprising means for performing any of the methods described herein, including, for example, means for receiving, from a network element, a configuration to send an indication of an uplink transmission adjustment to the network element. The apparatus may also include means for determining the presence of an overlap of uplink transmissions to the network element. The apparatus may further include means for, in response to determining the presence of an overlap of uplink transmissions, sending the indication to the network element. Additionally, the apparatus may include means for performing, in response to determining the presence of an overlap of uplink transmissions, at least one of an uplink transmission adjustment and an uplink scheduling adjustment for the uplink transmissions to the network element.

[0075] Other example embodiments may be directed to an apparatus comprising means for performing any of the methods described herein, for example, including means for configuring a user equipment to send an indication of an uplink transmission adjustment. The apparatus may also include means for receiving overlapping uplink transmissions from the user equipment. The apparatus may also include means for receiving an indication from the user equipment due to overlapping uplink transmissions.

[0076] Certain example embodiments described herein provide several technical improvements, enhancements, and / or advantages. For example, in some example embodiments, power reduction priorities (e.g., drops or significant power reductions) due to overlapping / parallel (or simultaneous) UL transmissions in existing procedures may be reflected. Other example embodiments may provide advantageous enhancements / improvements in PDCCH link adaptation (LA), PUSCH LA and adaptive transmission bandwidth (ATB), scheduling restrictions, active hybrid automatic repeat request (HARQ), and control message reliability.

[0077] For LA, the number of control channel elements (CCEs) used by the DCI can be determined by a PDCCH link quality metric derived from CQI feedback or UL PUSCH DTX, or both. Conventionally, an indication of PUSCH DTX can be a sufficient condition to reduce the estimated PDCCH link quality. In certain example embodiments, PUSCH DTX caused by the UE due to power (down) prioritization can be used as a cancellation condition to reduce the PDCCH link quality metric when the receiver determines DTX. The result is a reduction in PDCCH area utilization and PDCCH blocking without sacrificing PDCCH block error rate (BLER), thereby improving PUSCH throughput and reducing data latency.

[0078] For PUSCH LA and ATB, the UL modulation and coding scheme (MCS) and transmission bandwidth can be determined in part by a PUSCH link quality metric derived from any combination of UL signal-to-noise ratio (SINR) measurements, receiver DTX estimates, and HARQ ACK / NACK. When the receiver determines a NACK, the indication of power reduction due to power priority can be used as a cancellation condition to reduce the PUSCH link quality metric. In addition, the indication of the amount of power reduction due to simultaneous transmission can be used by link adaptation to limit the MCS and transmission bandwidth of future simultaneous transmissions. The result of these two applications for LA and ATB is improved user throughput.

[0079] In scheduling restrictions, UEs that have been instructed to undergo DTX (i.e., blanking) or a significant power reduction during simultaneous transmissions can be restricted to the UL scheduling list of lower priority cells. In addition, in proactive HARQ, transmissions that have been instructed to undergo DTX or with a significant power reduction can be automatically rescheduled, thereby reducing packet delay.

[0080] For control message reliability, during the transmission of control messages by a UE on a lower priority cell, transmit power reduction (via reducing frequency domain allocation or reducing power per resource block, or both) or transmit blanking can be applied to the UE on a higher priority cell. This allows UEs that have indicated significant power reduction or DTX during simultaneous transmission to improve the reliability of transmitted control messages. In addition, key performance indicators (KPIs) such as handover success rate and RRC reconfiguration success rate can also be improved.

[0081] The computer program product may include one or more computer executable components that are configured to perform some example embodiments when the program is run. The one or more computer executable components may be at least one software code or portion thereof. Modifications and configurations required to implement the functionality of some example embodiments may be performed as routines, which may be implemented as added or updated software routines.

[0082] As an example, the software or computer program code or part thereof may be in source code form, object code form or in some intermediate form, and it may be stored in some carrier, distribution medium or computer readable medium, which may be any entity or device capable of carrying the program. For example, such carriers may include recording media, computer memory, read-only memory, optical and / or electrical carrier signals, telecommunication signals and software distribution packages.
