Description

[Technical Field]

[0001] Some exemplary embodiments may relate generally to mobile or wireless telecommunications systems, such as Long Term Evolution (LTE) or fifth generation (5G) new radio (NR) access technologies, or 5G beyond, or sixth generation (6G) access technologies, or other communications systems. For example, certain exemplary embodiments may relate to enhanced operation for transmit power operation. [Background technology]

[0002] Examples of mobile or wireless telecommunications systems may include Universal Mobile Telecommunications System (UMTS) Terrestrial Radio Access Network (UTRAN), Long Term Evolution (LTE) Evolved UTRAN (E-UTRAN), LTE-Advanced (LTE-A), MultiFire, LTE-A Pro, fifth-generation (5G) or new radio (NR) access technologies, and / or sixth-generation (6G) radio access technologies. Fifth-generation (5G) and sixth-generation (6G) wireless systems refer to next-generation (NG) radio systems and network architectures. 5G and 6G network technologies are largely based on new radio (NR) technology, but 5G / 6G (or NG) networks can also be built on E-UTRAN radios. It is estimated that NR can provide bit rates of around 10-20 Gbit / s or more and can support at least enhanced mobile broadband (eMBB), ultra-reliable low-latency communications (URLLC), and massive machine-type communications (mMTC). NR is expected to deliver extremely high bandwidth, ultra-robust, low-latency connectivity, and large-scale networking to support the Internet of Things (IoT).

DETAILED DESCRIPTION OF THE INVENTION

[0017] It will be readily understood that the components of an exemplary embodiment, as generally described and illustrated in the Figures herein, could be arranged and designed in a wide variety of different configurations. Following are detailed descriptions of several exemplary embodiments of systems, methods, apparatuses, and computer program products for enhanced operation for transmit power operation.

[0018] The features, structures, or characteristics of the exemplary embodiments described throughout this specification may be combined in any suitable manner in one or more exemplary embodiments. For example, the use of the phrases “an embodiment,” “an exemplary embodiment,” “some embodiments,” or other similar phrases throughout this specification indicates that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment. Thus, the appearances of “an embodiment,” “an exemplary embodiment,” “some embodiments,” “another embodiment,” or other similar phrases throughout this specification do not necessarily refer to the same group of embodiments, and the described features, structures, or characteristics may be combined in any suitable manner in one or more exemplary embodiments. Furthermore, the terms “base station,” “cell,” “node,” “gNB,” “network,” or other similar phrases throughout this specification may be used interchangeably.

[0019] As used herein, "at least one of: " and "at least one of " and similar phrases where a list of two or more elements is joined by "and" or "or" 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.

[0020] New Radio (NR) Physical Uplink Shared Channel (PUSCH) power control may be based on a combination of open-loop and closed-loop power control. Open-loop power control may include support for partial path loss compensation, where the user equipment (UE) estimates uplink (UL) path loss based on downlink (DL) measurements and sets transmit power accordingly. Closed-loop power control, on the other hand, may be based on explicit transmit power control (TPC) commands provided by the network.

[0021] As described in the 3rd Generation Partnership Project (3GPP) specifications, the UE may determine the PUSCH transmit power. For example, the UE may 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 may be carried in downlink control information (DCI) that schedules the PUSCH transmission. The TPC command (and corresponding closed-loop index) may also be carried together to multiple UEs by group-common DCI using DCI format 2-2.

[0022] The PUSCH transmit power may depend on certain power control parameters. These power control parameters may be, for example, a closed loop index (e.g., TPC adjustment state), a TPC command (f b,f,c , absolute or accumulative TPC command), path loss reference signal (RS), p0(P 0_UE_PUSCH DELTA_TF (i.e., Δ TF,b,f,c (i)) DELTA_TF may model how the required received power varies when the number of information bits per resource element (BPRE) changes for different modulation schemes and channel coding rates.

[0023] If a UE transmits a PUSCH on an active UL bandwidth portion (BWP) b of carrier f of serving cell c using a parameter set configuration with index j and a PUSCH power control adjustment with index l, then the PUSCH transmit power P PUSCH,b,f,c (i,j,q d , l) can be determined. For example, the UE may determine the PUSCH transmit power P PUSCH,b,f,c (i,j,qd , l) can be determined as follows:

number

[0024] Sounding reference signal (SRS) power control may be similar to PUSCH power control. For example, the SRS transmit power may be determined based on when the UE transmits the SRS based on the configuration by the SRS-ResourceSet on the active UL bandwidth portion (BWP) b of carrier f of serving cell c using an SRS power control adjustment state with index l. For example, the UE may determine the SRS transmit power P SRS,b,f,c (i,q s , l) can be determined as follows:

number

[0025] When a UE transmits a physical uplink control channel (PUCCH) on an active UL BWP b of carrier f in a primary cell c using a PUCCH power control adjustment state with index l, the PUCCH transmit power may be determined. For example, the UE may determine a PUCCH transmit power P PUSCH,b,f,c (i,q u ,q d , l) can be determined as follows:

number

[0026] Transmit power reduction may be prioritized. For example, a procedure for prioritizing transmit power reduction may include parallel UL transmissions on different (serving) cells, such as in the case of carrier aggregation (CA) or dual connectivity. In single cell operation with two UL carriers, operation with CA, the total UE transmit power for PUSCH, PUCCH, Physical Random Access Channel (PRACH), or SRS transmissions on the serving cell in the frequency range at each transmit opportunity i is

number

number

number

[0027] When the priorities are the same, in operation with CA, the UE may prioritize power allocation for transmissions on a primary cell (PCell) of a master cell group (MCG) or secondary cell group (SCG) over transmissions on a secondary cell (SCell). When the priorities are the same, in operation with two UL carriers, if the UE is configured to transmit a PUCCH, the UE may prioritize power allocation for transmissions on the carrier. If a PUCCH is not configured for either of the two UL carriers, the UE may prioritize power allocation for transmissions on the non-auxiliary UL carrier.

[0028] LTE and NR support a power headroom (PHR) medium access control element (MAC CE), which includes the nominal UE maximum transmit power and 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 (from the above formula). The PHR report may also include (1) a P bit, which is a power backoff indication due to power management, and (2) a maximum permissible exposure (MPE) value, which is the amount of power backoff that meets the MPE requirement.

[0029] The P-bit and MPE (P-MPR) value may also be used to meet power exposure requirements. P-MPRc is a power management maximum power reduction to ensure compliance with applicable electromagnetic energy absorption requirements and to address unwanted emissions / performance defense requirements in cases of simultaneous transmissions for multiple radio access technologies (RATs) in scenarios not within the scope of 3GPP RAN specifications. P-MPRc may also be a power management maximum power reduction to ensure compliance with applicable electromagnetic energy absorption requirements in cases where proximity detection is used to address requirements requiring a lower maximum output power.

[0030] In some cases, for example, when a UE is power-limited due to overlapping UL transmissions (e.g., PUCCH / PUSCH / SRS / PRACH) in carrier aggregation or dual connectivity (i.e., a UE connected to two radio access technologies such as 5G and 6G), and more generally, in cases of overlapping / parallel UL transmissions on the same component carrier (CC) or different CCs / ULs / bandwidths, the UE may perform or apply one or more UL transmissions. For example, one exemplary UL transmission may first include scaling down the power or applying dropping to the lowest priority until the aggregate power is within a configured maximum transmit / output power (Pcmax), specifically within the total configured maximum output power (denoted as PCMAX or simply Pcmax). Another exemplary UL transmission may include scaling or dropping of all or part of the transmission, where the scaling or dropping may be left to the UE implementation. Therefore, when there is a Tx power reduction, SRS, PUCCH, and / or PUSCH may be affected due to either power reduction or (full / partial) dropping, which may then adversely affect UE performance in the UL or DL ​​due to the impact on CSI / HARQ-ACK reporting.

[0031] In some cases, the gNB may not recognize that the UE is applying dropping and / or (significant) Tx power reduction due to power reduction prioritization or because the UE is power limited. The gNB may also not infer that such an event has occurred at the UE. However, such an assumption would be time consuming (e.g., not timely knowledge) and would need to be based on some detection algorithm. Even so, this assumption would amount to nothing more than a guess by the gNB.

[0032] In view of the aforementioned drawbacks, certain exemplary embodiments may provide a method for reflecting power reduction prioritization (dropping or significant power reduction) due to overlapping / parallel (or simultaneous) UL transmissions. For example, FIG. 1 illustrates an exemplary overlap of UL transmissions and required Tx power. As illustrated in FIG. 1, the UE Pcmax covers the entire Tx power for UL transmissions in the PCell, while only a portion of the Tx power for UL transmissions in the SCell is covered. That is, the UE in this example applies power reduction due to overlapping UL transmissions in the PCell and SCell. Meanwhile, FIG. 2 illustrates another exemplary overlap of UL transmissions and required Tx power. As illustrated in FIG. 2, the UE Pcmax covers the entire Tx power for UL transmissions in the PCell and SCell#1, but no UE power is indicated for SCell#2. Therefore, the UE applies dropping, and UL transmissions are dropped from SCell#2. In the examples of FIGS. 1 and 2, the gNB is unaware of the power reduction and dropping. Furthermore, overlapping / parallel UL transmissions may occur across CCs / cells or carriers or cell groups, across bandwidths (or bandwidth portions), or within the same cell. As mentioned above, even if the gNB could infer / estimate power reduction and / or dropping, the process would be time-consuming and highly inefficient, i.e., with loose or no coordination between network entities receiving the transmissions, including cases of inter-band CA, dual connectivity or multi-RAT, and multi-transmission reception points (TRPs) (with non-ideal backhaul between TRPs).

[0033] FIG. 3 illustrates an example of dropping / blanking according to an exemplary embodiment, and FIG. 4 illustrates an example of power reduction according to an exemplary embodiment. As shown in FIG. 3, UL transmission on SCell #2 is dropped due to power reduction prioritization (e.g., when there are overlapping / parallel UL transmissions), which causes the UE to send an indication to the gNB. In another scenario, as shown in FIG. 4, the UE may perform significant power reduction (e.g., 6 dB or more) on the SCell due to power reduction prioritization (e.g., when there are overlapping / parallel UL transmissions), which causes the UE to send an indication to the gNB. In view of the UE's power limitations due to overlapping / parallel UL transmissions, the UE of an exemplary embodiment may provide an indication to the gNB. In some exemplary embodiments, the indication may include information indicating that the UE applies dropping / blanking due to power reduction prioritization / that the UE is power-limited due to overlapping / parallel UL transmissions. For example, a UE may be power limited when it has reached (or will reach) an overall power limit, or when it has reached / will reach a per-cell power limit. However, in some cases, power limiting may occur regardless of whether there are simultaneous transmissions. Furthermore, if the per-cell power limit is reached during simultaneous transmissions without reaching the configured per-cell power, one or more cells may reduce their power (or blank their transmissions) to still address the overall power constraint. In this context, power reduction prioritization may correspond to a rule by which per-cell Tx power reductions are ordered among cells during simultaneous transmissions.

[0034] In certain exemplary embodiments, the information may alternatively indicate that the UE is applying a (significant) Tx power reduction. For example, applying a significant Tx power reduction may be defined as a power reduction that results in a Tx power reduction greater than or less than a threshold defined by the gNB and communicated (e.g., via a Radio Resource Control (RRC) message) to the UE for power reduction prioritization for power-limited UEs. In another exemplary embodiment, a separate indication may be given from the UE to the gNB to indicate that the UE is not applying dropping due to power reduction prioritization. Alternatively or additionally, the UE may indicate that the UE is not applying a (significant) Tx power reduction due to power reduction prioritization.

[0035] According to certain exemplary embodiments, an indication may be transmitted from the UE to the gNB per CC or cell group, per bandwidth portion or bandwidth, per panel, per feature value set index, per control resource set pool index (CORESETPoolIndex), per reference signal set, or per TRP. According to some exemplary embodiments, the indication may include an index or identity (or ID) for one or more items / entities. The items / entities may include, for example, a CC / cell, cell group, bandwidth (or bandwidth portion), CORESET pool, panel ID, per feature value set index, TRP, remote radio head (RRH), node, and / or UL / DL reference signal resource set. In some exemplary embodiments, an index or identity (or ID) may be indicated if the UE applies dropping and / or (significant) Tx power reduction for / on the corresponding item / entity. Alternatively or additionally, any of the above indexes or identities (e.g., IDs) may be indicated if the UE has not applied dropping and / or (significant) Tx power reduction for / on the corresponding item / entity.

[0036] In one exemplary embodiment, the indication may include the identity of which UL signal / channel the information corresponds to or relates to. Furthermore, the indication may be transmitted by the UE to the gNB over at least one UL resource (e.g., PUCCH and PUSCH) on the cell / cell group that has been dropped and / or (significant) Tx power reduced due to power prioritization. Alternatively, in another exemplary embodiment, the indication may be sent on at least one UL resource corresponding to at least one dedicated configured cell, cell group, or link.

[0037] According to another exemplary embodiment, the indication may be carried through 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 may be a separate transmission (or a later transmission). In another exemplary embodiment, the UE may also be configured to send / multiplex UCI on the PUCCH / PUSCH (or any other UL channel or signal) of the SCell for which dropping and / or (significant) Tx power reduction due to power prioritization was performed if 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 may be a transmission (or a later transmission).

[0038] In certain exemplary embodiments, the UE may be configured to provide the indication in at least one of the overlapping UL transmissions. The UE may also be configured to provide the indication a predetermined period of time after the overlapping transmission (e.g., the first or last symbol of the overlapping or time-overlapping UL transmission). In some exemplary embodiments, the predetermined period of time may be configured by the gNB and communicated to the UE. As an alternative or in addition to the UCI, the UE may transmit the indication via a MAC CE over UL resources on the PCell or SCell. The exemplary embodiments described herein for the UCI may also be applicable for the MAC CE by replacing the UCI with the MAC CE.

[0039] According to certain example embodiments, the UE may indicate to the network (e.g., gNB) that an indication is carried in an UL channel / signal. This may be done using at least one bit via UCI or MAC CE, or using a reference signal selection by the UE, such as, for example, a dedicated demodulation reference signal (DMRS) configuration / sequence. Alternatively, the UE may send the indication to the network through UL resource selection. For example, the UE may select and / or transmit a dedicated UL resource (e.g., a scheduling-request-like resource), and then the network will know that an indication or a portion of an indication is being or needs to be sent based on this selection / transmission.

[0040] In some exemplary embodiments, the indication sent from the UE to the network may be conveyed through dedicated / shared periodic UL resources, semi-persistent UL resources, or scheduling-request-like resources (or resource configurations). Such resources may be configured per cell, cell group, TRP, or bandwidth. The UE may also indicate to the network that the dropping of UL transmissions corresponds to partial dropping or full dropping. The UE may further indicate to the network the number of transmissions, cells, links to which the UE has applied dropping and / or (significant) Tx power reduction.

[0041] 5 shows an example signal diagram according to an example embodiment. At 515, the UE 500 is configured by the network to provide an indication to the network of UE dropping / blanking transmissions due to power reduction prioritization when there is an overlapping UL transmission from the UE 500. At 520, the UE 500 determines there is an overlapping UL transmission, and the UE 500 may drop the UL transmission on the SCell 510 due to power reduction prioritization (i.e., because the UE is power-limited). At 525, the UE 500 transmits an indication of UL transmission dropping / blanking on the SCell to the network over the PCell. Alternatively, in another example embodiment, at 530, the UE 500 transmits an indication of UL transmission dropping / blanking on the PCell to the network over the SCell.

[0042] 6 illustrates an exemplary flow diagram of a method according to an exemplary embodiment. In an exemplary embodiment, the method of FIG. 6 may be performed by a network entity or a group of network elements in a 3GPP system, such as LTE or 5G-NR. For example, in an exemplary embodiment, the method of FIG. 6 may be performed by a UE similar to one of the devices 10 or 20 illustrated in FIG. 8.

[0043] 6, the method may include, at 600, receiving a configuration from a network element for transmitting an indication of an uplink transmission adjustment to the network element. The method may also include, at 605, determining the existence of overlapping uplink transmissions to the network element. The method may further include, at 610, transmitting the indication to the network element in response to determining the existence of overlapping uplink transmissions. Further, the method may include, at 615, making at least one of an uplink transmission adjustment or an uplink scheduling adjustment of the uplink transmissions to the network element in response to determining the existence of overlapping uplink transmissions.

[0048] In another exemplary embodiment, the physical uplink control channel or the physical uplink shared channel may be part of an overlapping uplink transmission or a different uplink transmission. In another exemplary embodiment, the indication may include information indicating a power reduction that is greater than the offset or that leads to a transmit power below a threshold.

[0066] In some exemplary embodiments, an apparatus (e.g., apparatus 10 and / or apparatus 20) may include means for performing any of the methods, processes, or variations discussed herein. Examples of means may include one or more processors, memories, controllers, transmitters, receivers, and / or computer program code for performing the operations.

[0067] Certain example embodiments may be directed to an apparatus including means for performing any of the methods described herein, including, for example, means for receiving from a network element a configuration for transmitting an indication of an uplink transmission adjustment to the network element. The apparatus may also include means for determining the existence of overlapping uplink transmissions to the network element. The apparatus may further include means for transmitting an indication to the network element in response to determining the existence of overlapping uplink transmissions. Furthermore, the apparatus may include means for performing at least one of an uplink transmission adjustment or an uplink scheduling adjustment of the uplink transmissions to the network element in response to determining the existence of overlapping uplink transmissions.

[0068] Another example embodiment may be directed to an apparatus including means for performing any of the methods described herein, including, for example, means for configuring a user equipment to transmit an indication of an uplink transmission adjustment. The apparatus may also include means for receiving an overlapping uplink transmission from the user equipment. The apparatus may further include means for receiving an indication due to the overlapping uplink transmission from the user equipment.

[0069] Certain example embodiments described herein provide several technical improvements, enhancements, and / or advantages. For example, some example embodiments may be able to reflect power reduction prioritization (e.g., dropping or significant power reduction) due to overlapping / parallel (or simultaneous) UL transmissions in existing procedures. Another example embodiment may provide advantageous extensions / improvements in PDCCH link adaptation (LA), PUSCH LA and adaptive and adaptive transmission bandwidth (ATB), scheduling constraints, proactive hybrid automatic repeat request (HARQ), and control message reliability.

[0070] In the LA, the number of control channel elements (CCEs) used by DCI is determined by a PDCCH link quality metric derived from CQI feedback, UL PUSCH DTX, or both. Traditionally, an indication of PUSCH DTX can be a sufficient condition to reduce the estimated PDCCH link quality. In an exemplary embodiment, when DTX is determined by the receiver, a UE with PUSCH DTX by power (de)prioritization can be used as a cancellation condition to reduce the PDCCH link quality metric. The result is reduced PDCCH space utilization without sacrificing PDCCH block error rate (BLER), reduced PDCCH blocking, improved PUSCH throughput, and reduced data latency.

[0071] In PUSCH LA and ATB, the UL modulation coding scheme (MCS) and transmission bandwidth are determined in part by a PUSCH link quality metric derived from UL signal-to-interference and noise ratio (SINR) measurements and any combination of DTX estimation and HARQ ACK / NACK at the receiver. When a NACK is determined by the receiver, an indication of power reduction due to power prioritization can serve as a canceling condition for reducing the PUSCH link quality metric. Furthermore, an indication with the amount of power reduction due to simultaneous transmission can be utilized by link adaptation to limit the MCS and transmission bandwidth of future simultaneous transmissions. Application to both LA and ATB results in higher user throughput.

[0072] With scheduling restrictions, UEs that are instructed to undergo DTX (i.e., blanking) or a significant amount of power reduction during simultaneous transmissions may be restricted from the UL scheduling list of lower prioritized cells. Furthermore, with proactive HARQ, transmissions that are instructed to undergo DTX or with a significant amount of power reduction may be automatically rescheduled, resulting in reduced packet latency.

[0073] For control message reliability, transmit power reduction (via reduced frequency domain allocation, reduced power per resource block, or both) or transmission blanking may be applied to UEs of higher-priority cells during control message transmission by UEs of lower-priority cells. This may enable UEs designated to experience significant power loss or DTX during simultaneous transmissions to improve control message transmission reliability. Furthermore, key performance indicators (KPIs), such as handover success rate, RRC reconfiguration success rate, etc., may be improved.

[0074] The computer program product may include one or more computer-executable components configured to perform some exemplary embodiments when the program is executed. The one or more computer-executable components may be at least one software code or a portion thereof. The modifications and configurations required to implement the functionality of an exemplary embodiment may be performed as routines, and the routines may be implemented as additional or updated software routines. The software routines may be downloaded into a device.

[0075] By way of example, the software or computer program code or portions thereof may be in source code form, object code form, or some intermediate form and may be stored in some kind of carrier, distribution medium, or computer-readable medium, which may be any entity or device capable of carrying a program. Such carriers may include, for example, recording media, computer memory, read-only memory, optical and / or electrical carrier signals, telecommunications signals, software distribution packages.

The computer-readable medium or computer-readable storage medium may be a non-transitory medium.
