Description

TITLEFLEXIBLE AND ADAPTIVE POWER COMPONENT UPDATETECHNICAL FIELD

[0001] Some example embodiments may generally relate to mobile or wireless telecommunication systems, such as 3rdGeneration Partnership Project (3GPP) Long Term Evolution (LTE), 5thgeneration (5G) radio access technology (RAT), new radio (NR) access technology, 6thgeneration (6G), and / or other communications systems. For example, certain example embodiments may relate to systems and / or methods for flexible and adaptive power component updates.BACKGROUND

[0002] Examples of mobile or wireless telecommunication systems may include radio frequency (RF) 5G RAT, the Universal Mobile Telecommunications System (UMTS) Terrestrial Radio Access Network (UTRAN), LTE Evolved UTRAN (E-UTRAN), LTE- Advanced (LTE-A), LTE-A Pro, NR access technology, 6G RAT, and / or MulteFire Alliance. 5G wireless systems refer to the next generation (NG) of radio systems and network architecture. A 5G system is typically built on a 5G NR, but a 5G (or NG) network may also be built on E-UTRA radio. It is expected that NR can support service categories such as enhanced mobile broadband (eMBB), ultra-reliable low-latency-communication (URLLC), and massive machine-type communication (mMTC). NR is expected to deliver extreme broadband, ultra- robust, low-latency connectivity, and massive networking to support the Internet of Things (loT). The next generation radio access network (NG-RAN) represents the radio access network (RAN) for 5G, which may provide radio access for NR, LTE, and LTE-A. It is noted that the nodes in 5G providing radio access functionality to a user equipment (e.g., similar to the Node B in UTRAN or the Evolved Node B (eNB) in LTE) may be referred to as next-generation Node B (gNB) when built on NR radio, and may be referred to as next-generation eNB (NG- eNB) when built on E-UTRA radio.SUMMARY

[0022] 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. Thus, the following detailed description of some example embodiments of systems, methods, apparatuses, and computer program products for flexible and adaptive power component updates is not intended to limit the scope of certain example embodiments, but is instead representative of selected example embodiments.

[0023] In NR, uplink power control may include a combination of open-loop power controls (e.g., support for fractional path-loss compensation, where the UE estimates the uplink (UL) path-loss based on downlink (DL) measurements, and sets the transmit power accordingly) and closed-loop power controls based on explicit value(s) of power component(s) such as, for example, transmit power-control (TPC) command, provided by the network.

[0024] For example, the UE may determine a physical uplink shared channel (PUSCH) transmission power by an indication or a determination of closed-loop parameters e.g., closed-loop index, TPC command) and open-loop parameters e.g., pathloss reference reference signal (RS), Po, a). The TPC command may be carried in the downlink control information (DCI) format configured to schedule the PUSCH transmission. The TPC command (and corresponding closed- loop index) may be carried jointly to multiple UEs via group-common DCI using DCI format 2-2.

[0025] Specifically, PUSCH transmission power may be based on a variety of power control parameters, such as closed-loop index (z.e., PC adjustment state), TPC command (e.g., b,fc(i,V) absolute or accumulative TPC command for active UL bandwidth part (BWP) b ofcarrier f of serving cell c with PUSCH power control adjustment state with index I in PUSCH transmission occasion i ), pre-configured target for received power, Po (z.e., PO_UE_PUSCH), and a (for partial or full path-loss compensation). Power control parameters may also include ATF (e.g.,power adjustment component based on transmission or transport format (TF) such as for example, modulation and coding scheme (MCS), for active UL BWP b of carrier f of serving cell c in PUSCH transmission occasion i), which may model how the required received power varies when the number of information bits per resource element (BPRE) changes due to different modulation schemes and channel-coding rates. Similar to PUSCH power control, PUCCH transmission power and sounding reference signal (SRS) transmission power can be determined. PUCCH transmission power and SRS transmission power may be determined similarly as PUSCH power control.

[0026] In a system with multiple transmission reception points (TRPs), a cross-TRP PDCCH order may be implemented, where one TRP may trigger, through a PDCCH order, physical random access channel (PRACH) towards another TRP (or the same TRP). This may be supported for inter-cell and intra-cell scenarios, and one additional PRACH configuration may be supported for each configured additionalP CI. The PDCCH order may include an indication of additionalP CI. The PDCCH may also include PRACH triggering towards servingCell PCI or active additionalP CI, without triggering towards an inactive additionalPCI. This may also utilize contention free random access (CFRA).

[0027] FIG. 1 illustrates an example of some RxP(s) / UL-only TRP(s) / UL-only node(s) to balance coverage / throughput / load between DL and UL. The gNB may be capable of transmitting signals over the air in UL and DL. The RxPs may be capable of receiving signals over the air only. The gNB may function as an anchor node in the deployment.

[0028] Some existing power control operations (e.g., closed loop power control) rely on selecting a predefined static transmit power command from a look up table from which the base station can select. However, this operation has some limitations, such as when considering UL transmissions or parts of a UL transmission (i.e., UL transmission parts) corresponding to different UL beams or TCI states; UL transmissions (or UL transmission parts) towards different TRPs (including UL-only node / TRP); and / or UL transmission (or UL transmission parts) from different UE antenna ports or UE panels, which may require significant power compensation for certain antenna ports or panels.

[0029] Certain example embodiments described herein may have various benefits and / or advantages to overcome the disadvantages described above. For example, certain example embodiments may address disadvantages of static and fixed ranges of closed loop power controls. Various example embodiments may enable flexible and adaptive power component range and / or granularity, especially when considering UL transmissions corresponding to different UL beams or TCI states, or UL transmissions (or transmission parts) towards different TRPs (including UL-only node / TRP), or UL transmission (or transmission parts) from different UE antenna ports or UE panels given. This may provide a more efficient and adaptive power control operation, improving throughput and coverage. Thus, certain example embodiments discussed below are directed to improvements in computer-related technology.

[0030] Certain example embodiments may provide adaptive power component ranges and / or granularities to accommodate different ranges / granularities for power control especially for UL transmissions (or UL transmission parts) when they are associated with different elements such as for example, different UL beams, TCI states, TRPs, antenna ports, etc., which may require different power component ranges and / or granularities.

[0031] FIG. 2 illustrates an example of a signaling diagram 200 depicting for flexible and adaptive power component updates. NE 210 and UE 220 may be similar to NE 510 and UE 520, as illustrated in FIG. 5, according to certain example embodiments. Although “power component” is used in the following description, “power parameter” may be used interchangeably.

[0032] At operation 201, UE 220 may transmit to NE 210 UE capability information indicating a number of power component ranges and / or granularities that UE 220 can support.

[0033] In certain example embodiments, UE 220 may transmit to NE 210 information through capability signaling, uplink control information (UCI), or UL medium access control (MAC) control elements (CE), indicating the number of power component ranges and / or granularities that UE 220 can support (e.g., per or across different elements), or regarding the range and / or granularity that UE 220 can support.

[0034] In some example embodiments, a power component range ranges / granularity may correspond to at least one of: received signal strength indicator (RS SI), reference signal received power (RSRP), reference signal received quality (RSRQ), signal-to-interference- plus-noise ratio (SINR), and ATF.

[0035] At operation 202, NE 210 may transmit to UE 220 an association of at least one element (e.g., TCI state) to at least one power component range or granularity. The at least one element may be associated with configuring a Tx power of an UL transmission. Alternatively, UE 220 may obtain the association of at least one element e.g., TCI state) to at least one power component range or granularity e.g., from a standard specification). In certain example embodiments, the association may be between a plurality of elements with a plurality of power component ranges or granularities.

[0036] In certain example embodiments, the Tx power may be configured for the at least one UL transmission or UL transmission part associated with, corresponding to, or conveyed through the at least one element.

[0037] A power component range / granularity may correspond to or be configured for at least one of power level, pathloss offset, pathloss, power offset, TPC, nominal power level, and / or pathloss compensation factor.

[0038] In some example embodiments, an UL transmission or UL transmission part may include transmitting one transport block or codeword from one or more PUSCH ports or antenna ports or transmission layers (or PUSCH port group or antenna port group or transmission layer group, where a group may include one or more ports or layers). A UL transmission or UL transmission part may correspond to transmitting at least two transport blocks or codewords from at least two PUSCH ports or antenna ports or transmission layers (or PUSCH port groups or antenna port groups or transmission layer group, where a group may include one or more ports or layers). Two (or more) UL transmission parts may correspond to different (or even same) frequency or spatial or time domain resources / allocations. For example, a transmission part may correspond to transmitting a first transmission layer from one antenna port group, and another transmission part may correspond to transmitting a second transmission layer from another antenna port group.

[0039] In some example embodiments, a power component range and / or granularity may be associated with at least one TCI state (or at least one spatial relation info), wherein the at least one TCI state (or spatial relation info) may be information including configurations such as quasi-colocation (QCL)-relationship between different antenna ports. For example, the power component range and / or granularity information may be included or indicated under TCI state. An association of TCI state to a power component range and / or granularity may be configured via radio resource control (RRC), and / or may be indicated / updated via MAC CE or DO. For aTCI state (or spatial relation info) that is indicated or is applicable for an UL transmission (e.g., PUSCH, PUCCH, SRS, PRACH) or UL transmission part, an indicated power component value (e.g., via DO or MAC CE) may be retrieved / determined based on the range / granularity associated with the indicated or applicable TCI state (or spatial relation info).

[0040] In certain example embodiments, a power component range and / or granularity may be associated with a power control adjustment state or with a closed loop (or with close loop power control index). For example, for a power control adjustment state that is applicable for or is associated with an UL transmission or UL transmission part (e.g., through associated TCI state), an indicated power component may be retrieved / determined based on the range / granularity associated with the TCI state.

[0041] In some example embodiments, a power component range and / or granularity may be associated with an antenna port group or UL signal (physical channel (such as PUSCH, PUCCH) or reference signal (such as SRS)) port group or transmission layer group; a port group may include one or more ports; or a layer group may include one or more layers. For a port group or layer group corresponding to an UL transmission or UL transmission part, an indicated power component may be retrieved / determined based on the range / granularity associated with the port group or layer group.

[0042] In various example embodiments, a power component range and / or granularity may be associated with at least one (serving) cell, component carrier (CC), carrier or bandwidth part (BWP), and / or frequency allocation / range. For an UL transmission or UL transmission part on a cell or CC or carrier or BWP or frequency allocation, an indicated power component may be retrieved / determined based on the range / granularity associated with the cell or CC or carrier or BWP or frequency allocation.

[0043] In certain example embodiments, a power component range and / or granularity may be associated with at least one TRP (transmission reception point) or CORESETPoolIndex or (DL / UL) RS resource(s) or RS resource set. For an UL transmission or UL transmission part corresponding to a TRP or CORESETPoolIndex or RS resource or RS resource set, an indicated power component may be retrieved / determined based on the range / granularity associated with the TRP or CORESETPoolIndex or RS resource or RS resource set.

[0044] In various example embodiments, a power component range and / or granularity may be configured per UL channel / signal type (such as PUCCH, PUSCH, SRS, PRACH) or may be common for multiple UL channel / signal types. For an UL transmission or UL transmission partcorresponding to a UL channel / signal type, an indicated power component may be retrieved / determined based on the range / granularity associated with the UL channel / signal type.

[0045] In certain example embodiments, a power component range and / or granularity may be associated with at least one MCS, or modulation and / or coding scheme, value, range, or with at least one subcarrier spacing or frequency band. For an UL transmission or UL transmission part corresponding to or using an MCS value(s) from the at least one MCS value or range, an indicated power component may be retrieved / determined based on the range / granularity associated with the at least one MCS value or range.

[0046] In some example embodiments, a power component range and / or granularity may be associated with at least one CORESET, search space set, or aggregation level. For example, for an UL transmission or UL transmission part corresponding to or scheduled through / using at least one CORESET, search space set or aggregation level, an indicated power component may be retrieved / determined based on the range / granularity associated with the at least one CORESET, or search space set or aggregation level.

[0047] In some example embodiments, at least two power component ranges and / or granularities may be associated with at least one element mentioned above, such as for example, at least one TCI state (or at least one spatial relation info). For example, at least two power component range and / or granularity information may be included or indicated under a TCI state. UE 220 may receive information indicative which power component range and / or granularity to use or is applicable, where information may be sent through DCI / PDCCH (such as the one corresponding to an UL transmission or UL transmission part) or MAC CE or RRC. Alternatively, UE 220 may be specified or configured with at least one rule or event based on which UE 220 determines applicable power component range and / or granularity from the at least two power component ranges and / or granularities.

[0048] In various example embodiments, in case of two stage DO, the first DO part may indicate information indicative of applicable range and / or granularity. Alternatively, that information may be indicated through PDCCH (e.g., corresponding aggregation level, CORESET, search space set, etc.) carrying the first DCI part.

[0049] In certain example embodiments, a power component range / granularity may have an identifier or index.

[0050] In some example embodiments, a power component range / granularity can be configured by RRC or system information block (SIB) and / or updated / indicated via MAC CE, or RRC, or DO.

[0051] In various example embodiments, multiple power component ranges / granularities may be updated via a same MAC CE or DO, or via separate MAC CEs or DCIs.

[0052] In certain example embodiments, the association of at least one power component range / granularity to at least one element may be indicated or updated via a RRC message, MAC CE or DO. Alternatively, the association may be at least partly specified or configured (e.g., in standard specification). In addition, there may be indication indicative of the at least one element for which the power component range / granularity is being updated / indicated in RRC message, MAC CE or DCI.

[0053] In some example embodiments, an element may be one or more of: a TCI state (or a spatial relation information), a power control adjustment state, a close loop power control index, an antenna port group, a UL channel / signal port group, a transmission layer group, a (serving) cell, a component carrier (CC), a carrier, a BWP, a frequency band, a frequency domain allocation, a TRP, a distributed unit (DU), a CORESETPoolIndex, a reference source or resource set, a UL channel / signal type, at least one modulation and coding scheme (MCS) value, at least one MCS range, a subcarrier spacing, at least one CORESET, an aggregation level, and / or at least one search space set.

[0054] In various example embodiments, information indicative that the MAC CE is for or is carrying association of at least one power component range / granularity to at least one element may be carried in the MAC CE header or sub-header. Furthermore, there may be information indicative that the MAC CE is for or is carrying update / indication of association of at least one power component range and / or granularity to at least one element.

[0055] In certain example embodiments, two or more power component ranges may correspond to a same e.g., look-up) table. Such ranges may each correspond to a subset of values from a (look-up) table. Alternatively, two or more power component ranges may correspond to different (look-up) tables.

[0056] In some example embodiments, the power component range and / or granularity may be determined / updated or predicted e.g., based on artificial intelligence / machine learning (AI / ML) model(s) at the network side and / or at the UE side or any algorithm that may allow such determination / update or prediction).

[0057] At operation 203, NE 210 may transmit to UE 220 at least one power component value for at least one element via DO or MAC CE.

[0058] At operation 204, UE 220 may determine / configure a Tx power associated with the at least one element based on the at least one power component value.

[0059] At operation 205, UE 220 may transmit to NE 210 a UL transmission or a UL transmission part using the Tx power determined / configured at least partially using the associated or applicable power component range or granularity.

[0060] FIG. 3 illustrates an example of a flow diagram of a method 300 that may be performed by a UE, such as UE 520 illustrated in FIG. 5, according to various example embodiments.
