Description

FIELD

The subject matter disclosed herein generally relates to wireless communications, and more particularly relates to methods and apparatuses for power control for simultaneous PUSCH transmission in a cell.

The following abbreviations are herewith defined, at least some of which are referred to within the following description: New Radio (NR), Very Large Scale Integration (VLSI), Random Access Memory (RAM), Read-Only Memory (ROM), Erasable Programmable Read-Only Memory (EPROM or Flash Memory), Compact Disc Read-Only Memory (CD-ROM), Local Area Network (LAN), Wide Area Network (WAN), User Equipment (UE), Evolved Node B (eNB), Next Generation Node B (gNB), Uplink (UL), Downlink (DL), Central Processing Unit (CPU), Graphics Processing Unit (GPU), Field Programmable Gate Array (FPGA), Orthogonal Frequency Division Multiplexing (OFDM), Radio Resource Control (RRC), User Entity/Equipment (Mobile Terminal), Transmitter (TX), Receiver (RX), Physical Uplink Control Channel (PUCCH), Physical Uplink Shared Channel (PUSCH), Sounding Reference Signal (SRS), Downlink Control Information (DCI), (CC), transmission reception point (TRP), control resource set (CORESET), Transmission Configuration Indicator (TCI), radio frequency (RF), Phase Locked Loop (PLL), Physical Downlink Control Channel (PDCCH), Transport Block (TB), Pathloss reference signal (PL-RS), Power headroom (PH), uplink shared channel (UL-SCH), power headroom report (PHR), band width part (BWP), Power Amplifier (PA), Phase Locked Loop (PLL).

Panel-selection based UL transmission was specified in NR Release 17 for a UE equipped with multiple panels which can be used for UL transmission. A UE may be equipped with multiple panels, while only one panel can be used for UL transmission at a time instant in NR Release 17 due to power limitation. It means that only one PUSCH transmission or one PUCCH resource or one SRS resource can be scheduled to be transmitted at a time instant in a carrier using one panel.

Advanced UEs can benefit from higher UL coverage and average throughput with simultaneous UL multi-panel transmission. It means that multiple panels (e.g. two panels) can be used for UL transmission at a time instant for a carrier. For multi-DCI based UL transmission, across different panels (e.g. two panels) in a same CC, PUSCH+PUSCH or PUCCH+PUCCH can be transmitted. It means that, if PUSCH transmission is transmitted by one panel of the two panels at a first given time instant, it is only allowed that another PUSCH transmission can be transmitted by the other panel of the two panels at the first give time instant of a carrier. Similarly, if PUCCH transmission is transmitted by one panel of the two panels at a second given time instant in a carrier, it is only allowed that another PUCCH transmission can be transmitted by the other panel of the two panels at the second give time instant.

This disclosure targets the issue of power control for simultaneous UL multi-panel transmission.

DETAILED DESCRIPTION

As will be appreciated by one skilled in the art that certain aspects of the embodiments may be embodied as a system, apparatus, method, or program product. Accordingly, embodiments may take the form of an entirely hardware embodiment, an entirely software embodiment (including firmware, resident software, micro-code, etc.) or an embodiment combining software and hardware aspects that may generally all be referred to herein as a “circuit”, “module” or “system”. Furthermore, embodiments may take the form of a program product embodied in one or more computer readable storage devices storing machine-readable code, computer readable code, and/or program code, referred to hereafter as “code”. The storage devices may be tangible, non-transitory, and/or non-transmission. The storage devices may not embody signals. In a certain embodiment, the storage devices only employ signals for accessing code.

Certain functional units described in this specification may be labeled as “modules”, in order to more particularly emphasize their independent implementation. For example, a module may be implemented as a hardware circuit comprising custom very-large-scale integration (VLSI) circuits or gate arrays, off-the-shelf semiconductors such as logic chips, transistors, or other discrete components. A module may also be implemented in programmable hardware devices such as field programmable gate arrays, programmable array logic, programmable logic devices or the like.

Modules may also be implemented in code and/or software for execution by various types of processors. An identified module of code may, for instance, include one or more physical or logical blocks of executable code which may, for instance, be organized as an object, procedure, or function. Nevertheless, the executables of an identified module need not be physically located together, but, may include disparate instructions stored in different locations which, when joined logically together, include the module and achieve the stated purpose for the module.

Indeed, a module of code may contain a single instruction, or many instructions, and may even be distributed over several different code segments, among different programs, and across several memory devices. Similarly, operational data may be identified and illustrated herein within modules and may be embodied in any suitable form and organized within any suitable type of data structure. This operational data may be collected as a single data set, or may be distributed over different locations including over different computer readable storage devices. Where a module or portions of a module are implemented in software, the software portions are stored on one or more computer readable storage devices.

Any combination of one or more computer readable medium may be utilized. The computer readable medium may be a computer readable storage medium. The computer readable storage medium may be a storage device storing code. The storage device may be, for example, but need not necessarily be, an electronic, magnetic, optical, electromagnetic, infrared, holographic, micromechanical, or semiconductor system, apparatus, or device, or any suitable combination of the foregoing.

A non-exhaustive list of more specific examples of the storage device would include the following: an electrical connection having one or more wires, a portable computer diskette, a hard disk, random access memory (RAM), read-only memory (ROM), erasable programmable read-only memory (EPROM or Flash Memory), portable compact disc read-only memory (CD-ROM), an optical storage device, a magnetic storage device, or any suitable combination of the foregoing. In the context of this document, a computer-readable storage medium may be any tangible medium that can contain or store a program for use by or in connection with an instruction execution system, apparatus, or device.

Code for carrying out operations for embodiments may include any number of lines and may be written in any combination of one or more programming languages including an object-oriented programming language such as Python, Ruby, Java, Smalltalk, C++, or the like, and conventional procedural programming languages, such as the “C” programming language, or the like, and/or machine languages such as assembly languages. The code may be executed entirely on the user's computer, partly on the user's computer, as a stand-alone software package, partly on the user's computer and partly on a remote computer or entirely on the remote computer or server. In the very last scenario, the remote computer may be connected to the user's computer through any type of network, including a local area network (LAN) or a wide area network (WAN), or the connection may be made to an external computer (for example, through the Internet using an Internet Service Provider).

Reference throughout this specification to “one embodiment”, “an embodiment”, or similar language means that a particular feature, structure, or characteristic described in connection with the embodiment is included in at least one embodiment. Thus, appearances of the phrases “in one embodiment”, “in an embodiment”, and similar language throughout this specification may, but do not necessarily, all refer to the same embodiment, but mean “one or more but not all embodiments” unless expressly specified otherwise. The terms “including”, “comprising”, “having”, and variations thereof mean “including but are not limited to”, unless otherwise expressly specified. An enumerated listing of items does not imply that any or all of the items are mutually exclusive, otherwise unless expressly specified. The terms “a”, “an”, and “the” also refer to “one or more” unless otherwise expressly specified.

Furthermore, described features, structures, or characteristics of various embodiments may be combined in any suitable manner. In the following description, numerous specific details are provided, such as examples of programming, software modules, user selections, network transactions, database queries, database structures, hardware modules, hardware circuits, hardware chips, etc., to provide a thorough understanding of embodiments. One skilled in the relevant art will recognize, however, that embodiments may be practiced without one or more of the specific details, or with other methods, components, materials, and so forth. In other instances, well-known structures, materials, or operations are not shown or described in detail to avoid any obscuring of aspects of an embodiment.

Aspects of different embodiments are described below with reference to schematic flowchart diagrams and/or schematic block diagrams of methods, apparatuses, systems, and program products according to embodiments.

“Multi-TRP” means that a serving cell can have multiple (e.g. two) TRPs. “Multi-panel” means that a UE can have multiple (e.g. two) panels. In the condition that a UE with two panels (e.g. panel #1 and panel #2) transmits UL signal (e.g. PUSCH transmissions) on a serving cell to two TRPs (e.g. TRP #1 and TRP #2), the UE may use one panel (e.g. panel #1) to transmit UL signal to one TRP (e.g. TRP #1) of the serving cell and use the other panel (e.g. panel #2) to transmit UL signal to another TRP (e.g. TRP #2) of the serving cell. So, one panel is associated with one TRP. For example, panel #1 is associated with TRP #1, and panel #2 is associated with TRP #2. So, multi-panel multi-TRP scenario can be described as multi-panel/TRP.

Incidentally, in the following description, ‘PUSCH transmission’ may be abbreviated as ‘PUSCH’, and ‘PUCCH resource’ may be abbreviated as ‘PUCCH’.

For multi-DCI based multi-panel/TRP UL transmission, each TRP may independently send DCI scheduling PUSCH or PUCCH to the same TRP. A UE may receive, from different (e.g. two) TRPs, multiple (e.g. two) DCIs scheduling multiple fully-overlapped or partial-overlapped or non-overlapped PUSCH or PUCCH transmissions in one slot. A RRC parameter coresetPoolIndex with value 0 or 1 is configured for a CORESET for TRP differential. For example, all CORESETs configured for TRP #1 is configured with coresetPoolIndex with value 0, and all the CORESETs configured for TRP #2 is configured with coresetPoolIndex with value 1.

“Multi-panel/TRP simultaneous UL transmission” means the UE transmit UL signals from multiple panels (e.g. two panels) to multiple TRPs (e.g. two TRPs) simultaneously.

“Multi-DCI based multi-panel/TRP simultaneous UL transmission” means that the UL signals (e.g. PUSCH) transmitted from multiple (e.g. two) panels to multiple TRPs (e.g. two TRPs) simultaneously are scheduled by multiple (e.g. two) DCIs. For example, the UL signal (e.g. PUSCH) transmitted from panel #1 to TRP #1 is scheduled by one DCI associated with coresetPoolIndex with value 0 (e.g. from TRP #1), and the UL signal (e.g. PUSCH) transmitted from panel #2 to TRP #2 is scheduled by another DCI associated with coresetPoolIndex with value 1 (e.g. from TRP #2) on the same symbol(s).

Two UL or joint TCI states associated with different coresetPoolIndex values are activated or indicated for UL signal transmitted from two panels to two TRPs for one BWP of a cell if unified TCI framework is configured, and are referred to as two indicated UL TCI states. UL TCI state is indicated when separate DL/UL TCI framework is configured, where the Tx beam for UL transmit and the Rx beam for DL reception are separately indicated by UL TCI state and DL TCI state, respectively. Each UL TCI state indicates a DL RS or an SRS for the UE to determine the TX spatial filter for UL transmission. In addition, a PL-RS is associated with the UL TCI state for the UE to calculate the DL channel path loss, and a set of power control parameters including P0, alpha and closed loop index for PUSCH is associated with each UL TCI state. Joint TCI state is indicated when joint DL/UL TCI framework is configured, where both Tx beam for UL transmission and Rx beam for DL reception are determined by the indicated joint TCI state. Each joint TCI state indicates a DL RS for the UE to determine the TX spatial filter for UL transmission, and the RX spatial filter for DL reception. In addition, a PL-RS is associated with the UL TCI state for the UE to calculate the DL channel path loss, and a set of power control parameters including P0, alpha and closed loop index for PUSCH is associated with each UL TCI state. Each PUSCH may be associated with one of the two indicated UL TCI states. For example, a first PUSCH scheduled by a first DCI associated with coresetPoolIndex value 0 is transmitted from panel #1 to TRP #1 associated with coresetPoolIndex value 0 by using the first indicated UL TCI state associated with coresetPoolIndex value 0 (i.e. the first indicated UL TCI state is applied to the first PUSCH), and a second PUSCH scheduled by a second DCI associated with coresetPoolIndex value 1 is transmitted from panel #2 to TRP #2 by using the second indicated UL TCI state associated with coresetPoolIndex value 1 (i.e. the second indicated UL TCI state is applied to the second PUSCH).

From UE hardware perspective, if the UE supports multi-panel simultaneous UL transmission, two independent RF chains or transmit branches each including independent PAs and PLLs should be equipped for the UE. Therefore, two maximum output power values for a carrier f of a serving cell c, e.g. P_CMAX,f,c,0 and P_CMAX,f,c,1, can be configured by the UE, where each of two maximum output power values corresponds to a configured maximum output power value associated with one panel. For example, P_CMAX,f,c,0 corresponds to a configured maximum output power value associated with panel #1 (or associated with coresetPoolIndex value 0), and P_CMAX,f,c,1 corresponds to a configured maximum output power value associated with panel #2 (or associated with coresetPoolIndex value 1). If power sharing is supported between different panels (e.g. between panel #1 and panel #2), an additional maximum output power value, e.g. P_CMAX,f,c (where P_CMAX,f,c<P_CMAX,f,c,0+P_CMAX,f,c,1), may be configured for a carrier to restrict the total output power of two panels in the carrier.

Three cases can be considered for configuring the maximum output power value.

Case 1: one maximum output power value P_CMAX,f,c is configured for a UE for carrier f of a serving cell c.

Case 2: two maximum output power values, e.g. P_CMAX,f,c,0 and P_CMAX,f,c,1 are configured for a UE for carrier f of a serving cell c, where each one of P_CMAX,f,c,0 and P_CMAX,f,c,1 is associated with a transmitter branch of a carrier and further associated with a UL panel, an indicated UL TCI state and a coresetPoolIndex value. For example, P_CMAX,f,c,0 is the maximum output power value associated with a first transmitter branch, panel #1, coresetPoolIndex value 0 and a first indicated UL TCI state (associated with coresetPoolIndex value 0); and P_CMAX,f,c,1 is the maximum output power value associated with a second transmitter branch, panel #2, coresetPoolIndex value 1 and a second indicated UL TCI state (associated with coresetPoolIndex value 1).

Case 3: three maximum output power values, e.g., P_CMAX,f,c, P_CMAX,f,c,0 and P_CMAX,f,c,1 are configured for a UE for carrier f of a serving cell c, where P_CMAX,f,c,0 and P_CMAX,f,c,1 are the same as P_CMAX,f,c,0 and P_CMAX,f,c,1 described in Case 2, and P_CMAX,f,c (where P_CMAX,f,c<P_CMAX,f,c,0+P_CMAX,f,c,1, and P_CMAX,f,c>P_CMAX,f,c,0, and P_CMAX,f,c>P_CMAX,f,C,1) corresponds to the maximum output power value of the carrier.

For fully-overlapped or partially-overlapped (which can be collectively referred to as overlapped) scheduled two PUSCHs, a first PUSCH refers to the PUSCH scheduled by DCI carried by PDCCH from CORESET configured with coresetPoolIndex=0 or without configured CORESET (for this case, the UE will assume coresetPoolIndex=0 for this CORESET), and a second PUSCH refers to the PUSCH scheduled by DCI carried by PDCCH from CORESET configured with coresetPoolIndex=1. In particular, the first PUSCH is transmitted from panel #1 to TRP #1 by applying the first indicated TCI state associated with coresetPoolIndex=0, and the second PUSCH is transmitted from panel #2 to TRP #2 by applying the second indicated TCI state associated with coresetPoolIndex=1.

The first to the third embodiments relate to determining the transmit power for each of the scheduled PUSCH(s) in one slot, respectively, in Cases 1, 2 and 3.

A first embodiment relates to Case 1, i.e. one maximum output power value P_CMAX,f,c is configured for a UE for carrier f of a serving cell c.

If only one PUSCH or two non-overlapped PUSCHs are scheduled to be transmitted in one slot, the transmit power of each scheduled PUSCH transmission occasion i is determined by Equation 1.

$\begin{array}{cc}{P}_{\mathrm{PUSCH},b,f,c}\left(i,j,q_d,l\right)=\min \left\{\begin{array}{c}{P}_{\mathrm{CMAX},f,c}\left(i\right)\\ \begin{array}{c}{P}_{O\_\mathrm{PUSCH},b,f,c}\left(j\right)+10{\log }_{10}\left(2^{\mu }·M_{\mathrm{RB},b,f,c}^{\mathrm{PUSCH}}\left(i\right)\right)+\\ {\alpha }_{b,f,c}\left(j\right)·{\mathrm{PL}}_{b,c,f}\left(q_d\right)+{\Delta }_{\mathrm{TF},b,f,c}\left(i\right)+f_{b,f,c}\left(i,l\right)\end{array}\end{array}\right\}& \mathrm{Equation}1\end{array}$

where, x=min{a, b} means that x equals to the minimal value between a and b. P_CMAX,f,c(i) is the configured maximum output power value P_CMAX,f,c for PUSCH transmission occasion i in the one slot. The parameters (i.e. P_{0_PUSCH,b,f,c}(j), M_RRB,b,f,c^PUSCH(l), α_b,f,c(j), PL_b,f,c(qa), Δ_TF,b,f,c(i), f_b,f,c(i, l)) to calculate P_PUSCH,b,f,c(i, j, q_d, l) are determined by the power control parameters associated with the indicated UL TCI state used for the PUSCH, and the scheduling DCI (i.e. the DCI scheduling the PUSCH). In detail, P_{0_PUSCH,b,f,c}(j) is the target receiving power at the gNB or TRP side of BWP b of carrier f of cell c. j corresponds to different PUSCH types, e.g., j=0 for PUSCH scheduled by DCI, j=1 for type 1 configured grant PUSCH, and j=2 for type 2 configured grant PUSCH. M_RB,b,f,c^PUSCH(i) is the number of PRBs scheduled for the PUSCH transmission, and 2″ corresponds to the sub-carrier space of the carrier of the cell. α_b,f,c(j) is the pathloss compensation factor with 0<αb,f,c(j)≤1. PL_b,f,c(qa) is the DL channel pathloss estimated based on a DL RS with index qa. Δ_TF,b,f,c(i) is the power adjustment according to the modulation of the scheduled PUSCH. f_b,f,c(i, l) is the closed loop power adjustment for the scheduled PUSCH transmission occasion i in closed loop I indicated by the scheduling DCI. For example, each indicated UL TCI state is associated with a P0 (i.e., P_{0_PUSCH,b,f,c}(j) in Equation 1), alpha (i.e., @b,f,c(j) in Equation 1) and l.

When two fully-overlapped or partially-overlapped PUSCHs (e.g. a first PUSCH associated with coresetPoolIndex=0, and a second PUSCH associated with coresetPoolIndex=1) are scheduled to be transmitted in one slot, the UE shall first determine the transmit power for each PUSCH by Equation 1. That is, a first candidate transmit power P_{PUSCH,b,f,c,0} (i, j, q_d, l) is determined for the first PUSCH (i.e. the PUSCH associated with coresetPoolIndex=0), where the parameters to calculate P_{PUSCH,b,f,c,0} (i, j, q_d, l) are determined according to the indicated UL TCI state applied to the first PUSCH. In addition, a second candidate transmit power P_{PUSCH,b,f,c,1} (i, j, q_d, l) is determined for the second PUSCH (i.e. the PUSCH associated with coresetPoolIndex=1), where the parameters to calculate P_{PUSCH,b,f,c,1} (i, j, q_d, l) are determined according to the indicated UL TCI state applied to the second PUSCH.

The UE further determines the actual transmit power for each of the first PUSCH and the second PUSCH according to the following procedure.

Step 11: if P_{PUSCH,b,f,c,0} (i, j, q_d, l)+P_{PUSCH,b,f,c,1} (i, j, q_d, l)≤P_CMAX,f,c(i), the UE transmits the first PUSCH with the first candidate transmit power of P_{PUSCH,b,f,c,0} (i, j, q_d, l), and transmits the second PUSCH with the second candidate transmit power of P_{PUSCH,b,f,c,1} (i, j, q_d, l).

Step 12: if P_{PUSCH,b,f,c,0} (i, j, q_d, l)+P_{PUSCH,b,f,c,1} (i, j, q_d, l)>P_CMAX,f,c(i), one the following solutions 11, 12 and 13 can be considered:

• • Solution 11: the UE directly allocates P_CMAX,f,c(i) to each of the first PUSCH and the second PUSCH proportionally according to the required transmit powers by the first PUSCH and the second PUSCH, for example,

$P_{\mathrm{PUSCH},b,f,c,0}^{\prime }\left(i,j,q_d,l\right)=\frac{P_{P\mathrm{USCH},b,f,c,0}\left(i,j,q_d,l\right)}{P_{PUSCH,b,f,c,0}\left(i,j,q_d,l\right)+P_{PUSCH,b,f,c,1}\left(i,j,q_d,l\right)}\times P_{\mathrm{CMAX},f,c}\left(i\right)$ $P_{\mathrm{PUSCH},b,f,c,1}^{\prime }\left(i,j,q_d,l\right)=\frac{P_{P\mathrm{USCH},b,f,c,1}\left(i,j,q_d,l\right)}{P_{PUSCH,b,f,c,0}\left(i,j,q_d,l\right)+P_{PUSCH,b,f,c,1}\left(i,j,q_d,l\right)}\times P_{\mathrm{CMAX},f,c}\left(i\right)$

where P′_{PUSCH,b,f,c,0}(i, j, q_d, l) is the actual transmit power for the first PUSCH, and P′_{PUSCH,b,f,c,1}(i, j, q_d, l) is the actual transmit power for the second PUSCH.

Solution 12: the UE allocates transmit power to the first PUSCH and the second PUSCH according to a priority. In detail, the UE first ensures the transmit power for the PUSCH with higher priority and then allocates the remaining power to the PUSCH with lower priority. For example, suppose the first PUSCH has a higher priority than the second PUSCH, then the UE allocates P_{PUSCH,b,f,c,0} (i, j, q_d, l) to the first PUSCH, and allocates (P_CMAX,f,c(i)-P_{PUSCH,b,f,c,0} (i, j, q_d, l)) to the second PUSCH. On the other hand, if the second PUSCH has a higher priority than the first PUSCH, then the UE allocates P_{PUSCH,b,f,c,1} (i, j, q_d, l) to the second PUSCH, and allocates (P_CMAX,f,c(i)−P_{PUSCH,b,f,c,1} (i, j, q_d, l)) to the first PUSCH. The priority can be determined by at least one of coresetPoolIndex value associated with each PUSCH, the TB size of each PUSCH, the start symbol index of each PUSCH, the end symbol index of each PUSCH, or the duration of each PUSCH. For example, any of criteria (11) to (15) can be used to determine which PUSCH has a higher priority:

• • (11) the PUSCH with larger TB size has higher priority than the PUSCH with smaller TB size;
  • (12) the PUSCH with smaller start symbol index has higher priority than the PUSCH with larger start symbol index;
  • (13) the PUSCH with smaller end symbol index has higher priority than the PUSCH with larger end symbol index;
  • (14) the PUSCH with larger duration has higher priority than the PUSCH with smaller duration; and
  • (15) the PUSCH associated with coresetPoolIndex=0 has higher priority than the PUSCH associated with coresetPoolIndex=1.

Incidentally, for each of criteria (11) to (14), if the compared values are the same, the priority of the PUSCHs is determined further by criterion (15).

Solution 13: the total power is allocated to the first PUSCH and the second PUSCH based on a RRC configured factor. For example, the gNB configures a power allocation factor, bate (with the range of 0<bate≤1), used for the total power allocation for two overlapped PUSCHs scheduled to be transmitted in one slot. When P_{PUSCH,b,f,c,0} (i, j, q_d, l)+P_{PUSCH,b,f,c,1} (i, j, q_d, l)>P_CMAX,f,c(i), bate*P_CMAX,f,c(i) is allocated to the first PUSCH (i.e. the PUSCH associated with coresetPoolIndex=0), and (1−bate)*P_CMAX,f,c(i) is allocated to the second PUSCH (i.e. the PUSCH associated with coresetPoolIndex=1).

Further, considering that transmitting a PUSCH with very low transmit power does not make sense, a dropping threshold can be configured or specified to determine whether the PUSCH with lower priority is transmitted. It means that, when the transmit power determined for a PUSCH (e.g. PUSCH with lower priority) is less than the dropping threshold, the PUSCH shall be dropped (i.e. not transmitted).

A second embodiment relates to Case 2, i.e. two maximum output power values, e.g. P_CMAX,f,c,0 and P_CMAX,f,c,1, are configured for a UE for carrier f of a serving cell c. In particular, P_CMAX,f,c,0 and P_CMAX,f,c,1 are associated with a first panel (e.g. panel #1) and a second panel (e.g. panel #2) used for simultaneous UL transmission. In multi-DCI based multi-panel/TRP scenario, P_CMAX,f,c,0 is the maximum output power value for the first PUSCH (i.e. the PUSCH associated with coresetPoolIndex=0) transmitted by the first panel (e.g. panel #0); and P_CMAX,f,c,1 is the maximum output power value for the second PUSCH (i.e. the PUSCH associated with coresetPoolIndex=1) transmitted by the second panel (e.g. panel #1).

The UE shall determine the transmit power for each of the first PUSCH and the second PUSCH according to the coresetPoolIndex value associated therewith.

In particular, the UE determines the transmit power for the first PUSCH (i.e. PUSCH associated with coresetPoolIndex=0) based on Equation 2.

$\begin{array}{cc}{P}_{\mathrm{PUSCH},b,f,c,0}\left(i,j,q_d,l\right)=\min \left\{\begin{array}{c}{P}_{\mathrm{CMAX},f,c,0}\left(i\right)\\ P_{O\_\mathrm{PUSCH},b,f,c}\left(j\right)+10{\log }_{10}\left(2^{\mu }·M_{\mathrm{RB},b,f,c}^{\mathrm{PUSCH}}\left(i\right)\right)+\\ {\alpha }_{b,f,c}\left(j\right)·{\mathrm{PL}}_{b,c,f}\left(q_d\right)+{\Delta }_{\mathrm{TF},b,f,c}\left(i\right)+f_{b,f,c}\left(i,l\right)\end{array}\right\}& \mathrm{Equation}2\end{array}$

where, P_CMAX,f,c,0 (i) is the configured maximum output power value P_CMAX,f,c,0 for PUSCH transmission occasion i in the one slot associated with coresetPoolIndex=0. Other parameters (i.e. P_{0_PUSCH,b,f,c}(j), M_RB,b,f,c^PUSCH(i), α_b,f,c(j), PL_b,f,c(aa), Δ_TF,b,f,c(i), f_b,f,c(i, l) to calculate P_{PUSCH,b,f,c,0} (i, j, q_d, l)) are determined by the power control parameters associated with the indicated UL TCI state associated with coresetPoolIndex=0 used for the PUSCH, and the scheduling DCI.

The UE determines the transmit power for the second PUSCH (i.e. PUSCH associated with coresetPoolIndex=1) based on Equation 3.

$\begin{array}{cc}{P}_{\mathrm{PUSCH},b,f,c,1}\left(i,j,q_d,l\right)=\min \left\{\begin{array}{c}{P}_{\mathrm{CMAX},f,c,1}\left(i\right)\\ P_{O\_\mathrm{PUSCH},b,f,c}\left(j\right)+10{\log }_{10}\left(2^{\mu }·M_{\mathrm{RB},b,f,c}^{\mathrm{PUSCH}}\left(i\right)\right)+\\ {\alpha }_{b,f,c}\left(j\right)·{\mathrm{PL}}_{b,c,f}\left(q_d\right)+{\Delta }_{\mathrm{TF},b,f,c}\left(i\right)+f_{b,f,c}\left(i,l\right)\end{array}\right\}& \mathrm{Equation}3\end{array}$

where, P_CMAX,f,c,1 (i) is the configured maximum output power value P_CMAX,f,c,1 for PUSCH transmission occasion i in the one slot associated with coresetPoolIndex=1. Other parameters (i.e. P_{0_PUSCH,b,f,c}(j), M_RB,b,f,c^PUSCH(i), α_b,f,c(j), PL_b,f,c(q_d), Δ_TF,b,f,c(i), f_b,f,c(i,l) to calculate P_{PUSCH,b,f,c,1} (i, j, q_d, l)) are determined by the power control parameters associated with the indicated UL TCI state associated with coresetPoolIndex=1 used for the PUSCH, and the scheduling DCI.

A third embodiment relates to Case 3, i.e. three maximum output power values, e.g. P_CMAX,f,c, P_CMAX,f,c,0 and P_CMAX,f,c,1, are configured for a UE for carrier f of a serving cell c.

P_CMAX,f,c,0 and P_CMAX,f,c,1 are the same as P_CMAX,f,c,0 and P_CMAX,f,c,1 described in the second embodiment. That is, P_CMAX,f,c,0 and P_CMAX,f,c,1 are associated with a first panel (e.g. panel #1) and a second panel (e.g. panel #2) used for simultaneous UL transmission. In multi-DCI based multi-panel/TRP scenario, P_CMAX,f,c,0 is the maximum output power value for the first PUSCH (i.e. the PUSCH associated with coresetPoolIndex=0) transmitted by the first panel (e.g. panel #0); and P_CMAX,f,c,1 is the maximum output power value for the second PUSCH (i.e. the PUSCH associated with coresetPoolIndex=1) transmitted by the second panel (e.g. panel #1).

P_CMAX,f,c is configured to restrict the total transmit power of the UE for carrier f of the serving cell c for simultaneous UL transmission. That is, P_CMAX,f,c<P_CMAX,f,c,0+P_CMAX,f,c,1, and P_CMAX,f,c,0>P_CMAX,f,c,0, P_CMAX,f,c>P_CMAX,f,c,1 are configured.

For a first PUSCH and a second PUSCH that are non-overlapped in the one slot, the UE determines the transmit power for each PUSCH according to Equation 2 or Equation 3 based on the coresetPoolIndex value associated with the PUSCH.

For a first PUSCH and a second PUSCH that are fully-overlapped or partially-overlapped (e.g. a first PUSCH associated with coresetPoolIndex=0, and a second PUSCH associated with coresetPoolIndex=1), the UE shall determine the transmit power for each PUSCH according to the following procedure:

Step 31: calculate P_{PUSCH,b,f,c,0} (i, j, q_d, l) for the first PUSCH according to Equation 2 and calculate P_{PUSCH,b,f,c,1} (i, j, q_d, l) for the second PUSCH according to or Equation 3.

Step 32: compare PUSCH,_b,f,c,0(i, j, q_d, l)+PUSCH,_b,f,c,1(i, j, q_d, l) and P_CMAX,f,c.

Step 321: if P_{PUSCH,b,f,c,0} (i, j, q_d, l)+P_{PUSCH,b,f,c,1} (i, j, q_d, l)≤P_CMAX,b,f,c, the UE shall transmit the first PUSCH with the transmit power P_{PUSCH,b,f,c,0} (i, j, q_d, l) and transmit the second PUSCH with the transmit power P_{PUSCH,b,f,c,1} (i, j, q_d, l).

Step 322: if P_{PUSCH,b,f,c,0} (i, j, q_d, l)+P_{PUSCH,b,f,c,1}(i, j, q_d, l)>P_CMAX,b,f,c, then one of the following four solutions can be considered to determine the transmit power for each PUSCH.

Solution 31: the UE first allocates P_CMAX,f,c(i) to each PUSCH proportionally according to the required transmit powers, for example,

$P_{\mathrm{PUSCH},b,f,c,0}^{\prime }\left(i,j,q_d,l\right)=\frac{P_{P\mathrm{USCH},b,f,c,0}\left(i,j,q_d,l\right)}{P_{PUSCH,b,f,c,0}\left(i,j,q_d,l\right)+P_{PUSCH,b,f,c,1}\left(i,j,q_d,l\right)}\times P_{\mathrm{CMAX},f,c}\left(i\right)$ $P_{\mathrm{PUSCH},b,f,c,1}^{\prime }\left(i,j,q_d,l\right)=\frac{P_{P\mathrm{USCH},b,f,c,1}\left(i,j,q_d,l\right)}{P_{PUSCH,b,f,c,0}\left(i,j,q_d,l\right)+P_{PUSCH,b,f,c,1}\left(i,j,q_d,l\right)}\times P_{\mathrm{CMAX},f,c}\left(i\right)$

The actual transmit power for the first PUSCH is determined by

{tilde over (P)}_{PUSCH,b,f,c,0}(i,j,q_d,l)=min{P_CMAX,f,c,0(i),P′_{PUSCH,b,f,c,0}(i,j,q_d,l)}

The actual transmit power for the second PUSCH is determined by P_{PUSCH,b,f,c,1} (i, j, q_d, l)=min {P_CMAX,f,c,1 (i), P′_{PUSCH,b,f,c,0}(i, j, q_d, l)}

Solution 32: the UE first allocates P_CMAX,f,c(i) to each PUSCH according to the configured maximum output power values for the first PUSCH and the second PUSCH, for example,

$P_{\mathrm{PUSCH},b,f,c,0}^{\prime }\left(i,j,q_d,l\right)=\frac{P_{\mathrm{CMAX},f,c,0}}{P_{\mathrm{CMAX},f,c,0}+P_{\mathrm{CMAX},f,c,1}}\times P_{\mathrm{CMAX},f,c}\left(i\right)$ $P_{\mathrm{PUSCH},b,f,c,1}^{\prime }\left(i,j,q_d,l\right)=\frac{P_{\mathrm{CMAX},f,c,1}}{P_{\mathrm{CMAX},f,c,0}+P_{\mathrm{CMAX},f,c,1}}\times P_{\mathrm{CMAX},f,c}\left(i\right)$

The actual transmit power for the first PUSCH is determined by

{tilde over (P)}_{PUSCH,b,f,c,0}(i,j,q_d,l)=min{P_CMAX,f,c,0(i),P′_{PUSCH,b,f,c,0}(i,j,q_d,l)}

The actual transmit power for the second PUSCH is determined by

{tilde over (P)}_{PUSCH,b,f,c,1}(i,j,q_d,l)=min{P_CMAX,f,c,1(i),P′_{PUSCH,b,f,c,0}(i,j,q_d,l)}

Solution 33: the UE allocates transmit power for the first PUSCH and transmit power for the second PUSCH according to a priority. In detail, the UE first ensures the transmit power for the PUSCH with higher priority and then allocates the remaining power to the PUSCH with lower priority. For example, suppose the first PUSCH has a higher priority than the second PUSCH, then the UE allocates P_{PUSCH,b,f,c,0} (i, j, q_d, l) to the first PUSCH, and allocates (P_CMAX,f,c(i)-P_{PUSCH,b,f,c,0} (i, j, q_d, l)) to the second PUSCH. On the other hand, if the second PUSCH has a higher priority than the first PUSCH, then the UE allocates P_{PUSCH,b,f,c,1} (i, j, q_d, l) to the second PUSCH, and allocates (P_CMAX,f,c(i)-P_{PUSCH,b,f,c,1} (i, j, q_d, l)) to the first PUSCH.

The priority can be determined by at least one of coresetPoolIndex value associated with each PUSCH, the TB size of each PUSCH, the start symbol index of each PUSCH, the end symbol index of each PUSCH, and the duration of each PUSCH. For example, any of criteria (31) to (35) can be used to determine which PUSCH has a higher priority:

• • (31) the PUSCH with larger TB size has higher priority than the PUSCH with smaller TB size;
  • (32) the PUSCH with smaller start symbol index has higher priority than the PUSCH with larger start symbol index;
  • (33) the PUSCH with smaller end symbol index has higher priority than the PUSCH with larger end symbol index;
  • (34) the PUSCH with larger duration has higher priority than the PUSCH with smaller duration; and
  • (35) the PUSCH associated with coresetPoolIndex=0 has higher priority than the PUSCH associated with coresetPoolIndex=1.

Incidentally, for each of criteria (31) to (34), if the compared values are the same, the priority of the PUSCHs is determined further by criterion (35).

Solution 34: the total power is allocated to the first PUSCH and the second PUSCH based on a RRC configured factor. For example, the gNB configures a power allocation factor, bate (with the range of 0≤bate≤1), used for the total power allocation for two overlapped PUSCHs scheduled to be transmitted in one slot. When P_{PUSCH,b,f,c,0} (i, j, q_d, l)+P_{PUSCH,b,f,c,1} (i, j, q_d, l)>P_CMAX,f,c(i), bate*P_CMAX,f,c(i) is allocated to the first PUSCH (i.e. the PUSCH associated with coresetPoolIndex=0), and (1−bate)*P_CMAX,f,c(i) is allocated to the second PUSCH (i.e. the PUSCH associated with coresetPoolIndex=1).

Further, considering that transmitting a PUSCH with very low transmit power does not make sense, a dropping threshold can be configured or specified to determine whether the PUSCH with lower priority is transmitted. It means that, when the transmit power determined for a PUSCH (e.g. PUSCH with lower priority) is less than the dropping threshold, the PUSCH shall be dropped (i.e. not transmitted).

The fourth embodiment to the sixth embodiment relate to calculating power headroom (PH).

Power headroom (PH) indicates the power availability for UL transmission. Type 1 PH reflects the PH assuming that PUSCH only transmits on a carrier and the PH is a measurement of the difference between the maximum output power value and the transmit power value that would have been used assuming that there would have been no upper limit on the transmit power. The PH can be transmitted from the UE to the gNB when the UE is scheduled to transmit on the UL-SCH. For example, when PUSCH(s) are scheduled to be transmitted from the UE, a PHR (power headroom report) including one or multiple PHs can be transmitted to the gNB. For example, for the UE supporting simultaneous UL transmission in multi-DCI multi-TRP mode, the gNB can configure the UE to report multiple PHs in a PHR in a cell according to UE capability report on whether multiple PHs (e.g., two PHs) can be configured in a cell.

So, multiple PHs are necessary to be calculated.

A fourth embodiment relates to calculating PHs in Case 1, i.e. one maximum output power value P_CMAX,f,c is configured for a UE for carrier f of a serving cell c.

According to the fourth embodiment, two or three PHs can be configured to be reported in a PHR for a cell.

When only one PUSCH is scheduled in one slot, if the UE is configured to report more than one PH (e.g. two PHs) in a cell, a first PH is an actual PH based on the PUSCH transmission, and a second PH is a virtual PH based on a reference PUSCH transmission with the power control parameters associated with a coresetPoolIndex value different from the coresetPoolIndex value associated with the actual PUSCH transmission.

When two non-overlapped PUSCHs are scheduled in one slot, two actual PHs, e.g. a first actual PH (i.e. PH_{type1,b,f,c,0}(i, j, q_d, l)) calculated according to the power control parameters associated with the first coresetPoolIndex (e.g. coresetPoolIndex=0) and a second actual PH (i.e. PH_{type1,b,f,c,1}(i, j, q_d, l)) calculated according to the power control parameters associated with the second coresetPoolIndex (e.g. coresetPoolIndex=1), are calculated.

For example, the first actual PH (i.e. PH_{type1,b,f,c,0}(i, j, q_d, l)) is calculated according to Equation 4.

$\begin{array}{cc}P{H}_{\mathrm{type}1,b,f,c,0}\left(i,j,q_d,l\right)=P_{CM\mathrm{AX},f,c}\left(i\right)-\left\{P_{O_{\mathrm{PUSCH}},b,f,c,0}\left(j\right)+10{\log }_{10}\left(2^{\mu }·M_{RB,b,f,c}^{PUS\mathrm{CH},0}\left(i\right)\right)+{\alpha }_{b,f,c,0}\left(j\right)·{\mathrm{PL}}_{b,f,c,0}\left(q_d\right)+{\Delta }_{TF,b,f,c,0}\left(i\right)+f_{b,f,c,0}\left(i,l\right)\right\}& \mathrm{Equation}4\end{array}$

where, P_CMAX,f,c(i) is the configured maximum output power value P_CMAX,f,c for PUSCH transmission occasion i in the one slot; the parameters P_{OPUSCH,b,f,c,0}(j), M_RB,b,f,c^PUSCH,0(i), α_b,f,c,0(j), P_Lb,f,c,0(qa), ΔT_F,b,f,c,0(i), f_b,f,c,0(i, l) are determined by the power control parameters associated with the indicated UL TCI state associated with coresetPoolIndex=0 used for the PUSCH, and the scheduling DCI.

The second actual PH (i.e. PH_{type1,b,f,c,1}(i, j, q_d, l)) is calculated according to Equation 5.

$\begin{array}{cc}P{H}_{\mathrm{type}1,b,f,c,1}\left(i,j,q_d,l\right)=P_{CM\mathrm{AX},f,c}\left(i\right)-\left\{P_{O\_\mathrm{PUSCH},b,f,c,1}\left(j\right)+10{\log }_{10}\left(2^{\mu }·M_{RB,b,f,c}^{PUS\mathrm{CH},1}\left(i\right)\right)+{\alpha }_{b,f,c,1}\left(j\right)·{\mathrm{PL}}_{b,f,c,1}\left(q_d\right)+{\Delta }_{TF,b,f,c,1}\left(i\right)+f_{b,f,c,1}\left(i,l\right)\right\}& \mathrm{Equation}5\end{array}$

where, P_CMAX,f,c(i) is the configured maximum output power value P_CMAX,f,c for PUSCH transmission occasion i in the one slot; the parameters PO_{PUSCH,b,f,c,1}(j), M_RB,b,f,c^PUSCH,1((i), α_b,f,c,1(j), PL_b,f,c,1(q_d), Δ_TF,b,f,c,1(i), f_b,f,c,1(i, l) are determined by the power control parameters associated with the indicated UL TCI state associated with coresetPoolIndex=1 used for the PUSCH, and the scheduling DCI.

When two fully-overlapped or partially-overlapped PUSCHs are scheduled in one slot, in addition to the first actual PH (i.e. PH_{type1,b,f,c,0}(i, j, q_d, l)) and the second actual PH (i.e. PH_{type1,b,f,c,1}(i, j, q_d, l)), one additional PH (i.e. PH_{type1,b,f,c,2} (i, j, q_d, l)) can be calculated according to Equation 6.

$\begin{array}{cc}P{H}_{\mathrm{type}1,b,f,c,2}\left(i,j,q_d,l\right)=P_{CM\mathrm{AX},f,c}\left(i\right)-\left\{P_{O\_\mathrm{PUSCH},b,f,c,0}\left(j\right)+10{\log }_{10}\left(2^{\mu }·M_{\mathrm{RB},b,f,c}^{PUS\mathrm{CH},0}\left(i\right)\right)+{\alpha }_{b,f,c,0}\left(j\right)·{\mathrm{PL}}_{b,f,c,0}\left(q_d\right)+{\Delta }_{TF,b,f,c,1}\left(i\right)+f_{b,f,c,0}\left(i,l\right)\right\}-\left\{P_{O\_\mathrm{PUSCH},b,f,c,1}\left(j\right)+10{\log }_{10}\left(2^{\mu }·M_{\mathrm{RB},b,f,c}^{PUS\mathrm{CH},1}\left(i\right)\right)+{\alpha }_{b,f,c,1}\left(j\right)·{\mathrm{PL}}_{b,f,c,1}\left(q_d\right)+{\Delta }_{TF,b,f,c,1}\left(i\right)+f_{b,f,c,1}\left(i,l\right)\right\}& \mathrm{Equation}6\end{array}$

where, P_CMAX,f,c(i) is the configured maximum output power value P_CMAX,f,c for PUSCH transmission occasion i in the one slot; the parameters P_{OPUSCH,b,f,c,0}(j), M_RB,b,f,c^PUSCH(i), α_b,f,c,0(j), P_Lb,f,c,0(qa), ΔT_F,b,f,c,0(i), f_b,f,c,0(i, l) are determined by the power control parameters associated with the indicated UL TCI state associated with coresetPoolIndex=0 used for the PUSCH, and the scheduling DCI. The parameters P_{OPUSCH,b,f,c,1}(j), M_RB,b,f,c^PUSCH,1(i), α_b,f,c,1(j), PL_b,f,c,1(q_d), Δ_TF,b,f,c,1(i), f_b,f,c,1(i, l)) are determined by the power control parameters associated with the indicated UL TCI state associated with coresetPoolIndex=1 used for the PUSCH, and the scheduling DCI.

It means that three PHs can be calculated and reported in one PHR for a cell and PH_{type1,b,f,c,2} (i, j, q_d, l) reflects the power headroom assuming that the overlapped PUSCHs are transmitted with the expected powers.

A fifth embodiment relates to calculating PHs in Case 2, i.e. two maximum output power values, e.g. P_CMAX,f,c,0 and P_CMAX,f,c,1, are configured for a UE for carrier f of a serving cell c.

According to the fifth embodiment, the gNB can configure the UE to report two PHs (e.g. a first PH and a second PH) in a PHR for a cell according to UE capability report.

When only one PUSCH is scheduled in one slot, and the UE the UE is triggered to report PHR, wherein the first PH is an actual PH calculated according to the actual PUSCH transmission based on Equation 7 (if the actual PUSCH transmission is associated with coresetPoolIndex=0) or Equation 8 (if the actual PUSCH transmission is associated with coresetPoolIndex=1).

$\begin{array}{cc}P{H}_{\mathrm{type}1,b,f,c,0}\left(i,j,q_d,l\right)=P_{CM\mathrm{AX},f,c}\left(i\right)-\left\{P_{O\_\mathrm{PUSCH},b,f,c,0}\left(j\right)+10{\log }_{10}\left(2^{\mu }·M_{RB,b,f,c}^{PUS\mathrm{CH},0}\left(i\right)\right)+{\alpha }_{b,f,c,0}\left(j\right)·{\mathrm{PL}}_{b,f,c,0}\left(q_d\right)+{\Delta }_{TF,b,f,c,0}\left(i\right)+f_{b,f,c,0}\left(i,l\right)\right\}& \mathrm{Equation}7\end{array}$

where, P_CMAX,f,c,0 (i) is the configured maximum output power value P_CMAX,f,c,0 for PUSCH transmission occasion i in the one slot; the parameters P_{OPUSCH,b,f,c,0}(j), M_RB,b,f,c^PUSCH(i), α_b,f,c,0(j), P_Lb,f,c,0(qa), ΔT_F,b,f,c,0(i), f_b,f,c,0(i, l) are determined by the power control parameters associated with the UL TCI state associated with coresetPoolIndex=0 used for the PUSCH transmission, and the scheduling DCI.

$\begin{array}{cc}{\mathrm{PH}}_{\mathrm{type}1,b,f,c,1}\left(i,j,q_d,l\right)=P_{\mathrm{CMAX},f,c,1}\left(i\right)-\left\{P_{O\_\mathrm{PUSCH},b,f,c,1}\left(j\right)+10{\log }_{10}\left(2^{\mu }·M_{\mathrm{RB},b,f,c}^{\mathrm{PUSCH},1}\left(i\right)\right)+{\alpha }_{b,f,c,1}\left(j\right)·{\mathrm{PL}}_{b,f,c,1}\left(q_d\right)+{\Delta }_{\mathrm{TF},b,f,c,1}\left(i\right)+f_{b,f,c,1}\left(i,l\right)\right\}& \mathrm{Equation}8\end{array}$

where, P_CMAX,f,c,1 (i) is the configured maximum output power value P_CMAX,f,c,1 for PUSCH transmission occasion i in the one slot; the parameters P_{OPUSCH,b,f,c,1}(j), M_RB,b,f,c^PUSCH,1(i), α_b,f,c,1(j), PL_b,f,c,1(q_d), Δ_TF,b,f,c,1(i), f_b,f,c,1(i, l) are determined by the power control parameters associated with the UL TCI state associated with coresetPoolIndex=1 used for the PUSCH transmission, and the scheduling DCI.

The second PH is a virtual PH calculated according to a reference PUSCH transmission with the power control parameters associated with the indicated UL TCI state associated with a coresetPoolIndex value different from the coresetPoolIndex value associated with the actual PUSCH transmission based on Equation 9 (if the reference PUSCH transmission is associated with coresetPoolIndex=0) or Equation 10 (if the reference PUSCH transmission is associated with coresetPoolIndex=1).

$\begin{array}{cc}{\mathrm{PH}}_{\mathrm{type}1,b,f,c,0}\left(i,j,q_d,l\right)={\tilde{P}}_{\mathrm{CMAX},f,c,0}\left(i\right)-\left\{P_{O\_\mathrm{PUSCH},b,f,c,0}\left(j\right)+{\alpha }_{b,f,c,0}\left(j\right)·{\mathrm{PL}}_{b,f,c,0}\left(q_d\right)+f_{b,f,c,0}\left(i,l\right)\right\}& \mathrm{Equation}9\end{array}$

where, {tilde over (P)}_CMAX,f,c,0 (i) is computed from P_CMAX,f,c,0 (i) assuming MPR (which is allowed maximum power reduction)=0 dB, A-MPR (which is additional maximum power reduction)=0, P-MPR=0 dB, ΔTc (which is allowed operating band edge transmission power relaxation)=0 dB defined in [8-1, TS 38.101-1], [8-2, TS38.101-2] and [8-3, TS 38.101-3]; and the parameters P0PUSCH,b,f,c,0(j), α_b,f,c,0(j), P_Lb,f,c,0(qa), f_b,f,c,0(i, l) are determined by default power control parameters associated with coresetPoolIndex=0.

where, {tilde over (P)}_CMAX,f,c,1 (i) is computed from P_CMAX,f,c,1 (i) assuming MPR=0 dB, A-MPR=0, P-MPR=0 dB, ΔTc=0 dB; and the parameters P_{OPUSCH,b,f,c,1}(j), α_b,f,c,1(j), PL_b,f,c,1(q_d), f_b,f,c,1(i, l) are determined by default power control parameters associated with coresetPoolIndex=1.

In particular, the first actual PH is calculated based on the first PUSCH associated with coresetPoolIndex=0 according to Equation 7, and the second actual PH is calculated based on the second PUSCH associated with coresetPoolIndex=1 according to Equation 8.

A sixth embodiment relates to calculating PHs in Case 3, i.e. three maximum output power values, e.g. P_CMAX,f,c, P_CMAX,f,c,0 and P_CMAX,f,c,1, are configured for a UE for carrier f of a serving cell c.

According to the sixth embodiment, two or three PHs can be configured to be reported in a PHR for a cell according to UE capability report.

When only one PUSCH is scheduled in one slot, and the UE is triggered to report PHR in the same slot, the first PH is an actual PH calculated according to the one PUSCH based on Equation 7 (if the one PUSCH is associated with coresetPoolIndex=0) or Equation 8 (if the one PUSCH is associated with coresetPoolIndex=1), and the second PH is a virtual PH calculated according to a reference PUSCH transmission with the power control parameters associated with the indicated UL TCI state associated with a coresetPoolIndex value different from the coresetPoolIndex value associated with the actual PUSCH transmission based on Equation 9 (if the reference PUSCH transmission is associated with coresetPoolIndex=0) or Equation 10 (if the reference PUSCH transmission is associated with coresetPoolIndex=1).

In particular, the first actual PH is calculated based on the first PUSCH associated with coresetPoolIndex=0 according to Equation 7, and the second actual PH is calculated based on the second PUSCH associated with coresetPoolIndex=1 according to Equation 8.

When fully-overlapped or partially-overlapped PUSCHs are scheduled in one slot, an additional PH can be calculated according to Equation 6.

FIG. 1 is a schematic flow chart diagram illustrating an embodiment of a method 100 according to the present application. In some embodiments, the method 100 is performed by an apparatus, such as a remote unit (e.g. UE). In certain embodiments, the method 100 may be performed by a processor executing program code, for example, a microcontroller, a microprocessor, a CPU, a GPU, an auxiliary processing unit, a FPGA, or the like.

In a first implementation, if the configuration configures one maximum output power value P_CMAX,f,c, and one of the first PUSCH transmission and the second PUSCH transmission is scheduled in the one slot or the first PUSCH transmission and the second PUSCH transmission are scheduled to be non-overlapped in the one slot, then, the transmit power for each of the scheduled PUSCH transmission(s) is determined according to the one maximum output power value P_CMAX,f,c, power control parameters associated with an indicated TCI state used for the scheduled PUSCH transmission and the DCI scheduling the PUSCH transmission.

In a second implementation, if the configuration configures one maximum output power value P_CMAX,f,c, and the first PUSCH transmission and the second PUSCH transmission are scheduled to be overlapped in the one slot, then, a first candidate transmit power P_{PUSCH,b,f,c,0} for the first PUSCH transmission is determined according to the one maximum output power value P_CMAX,f,c and power control parameters associated with a first indicated TCI state applied for the first PUSCH transmission, and a second candidate transmit power P_{PUSCH,b,f,c,1} for the second PUSCH transmission is determined according to the one maximum output power value P_CMAX,f,c and power control parameters associated with a second indicated TCI state applied for the second PUSCH transmission, and if P_{PUSCH,b,f,c,0}+P_{PUSCH,b,f,c,1}≤P_CMAX,f,c, the transmit power for the first PUSCH transmission is the first candidate transmit power P_{PUSCH,b,f,c,0}, and the transmit power for the second PUSCH transmission is the second candidate transmit power P_{PUSCH,b,f,c,1}, if P_{PUSCH,b,f,c,0}+P_{PUSCH,b,f,c,1}>P_CMAX,f,c, the transmit power for the first PUSCH transmission and the transmit power for the second PUSCH transmission are determined according to one of the following manners 1 to 3: manner 1: the transmit power for the first PUSCH transmission is

$\frac{P_{\mathrm{PUSCH},b,f,c,0}}{P_{\mathrm{PUSCH},b,f,c,0}+P_{\mathrm{PUSCH},b,f,c,1}}\times P_{\mathrm{CMAX},f,c},$

and the transmit power for the second PUSCH transmission is

$\frac{P_{\mathrm{PUSCH},b,f,c,1}}{P_{\mathrm{PUSCH},b,f,c,0}+P_{\mathrm{PUSCH},b,f,c,1}}\times P_{\mathrm{CMAX},f,c},$

In particular, the method may further comprise transmitting the first PUSCH transmission with the transmit power for the first PUSCH transmission if the transmit power for the first PUSCH transmission is higher than a dropping threshold; and transmitting the second PUSCH transmission with the transmit power for the second PUSCH transmission if the transmit power for the second PUSCH transmission is higher than the dropping threshold. In addition, the priority of the first PUSCH transmission and the second PUSCH transmission is determined according to at least one of coresetPoolIndex value associated with each of the first PUSCH transmission and the second PUSCH transmission, a TB size of each of the first PUSCH transmission and the second PUSCH transmission, a start symbol index of each of the first PUSCH transmission and the second PUSCH transmission, an end symbol index of each of the first PUSCH transmission and the second PUSCH transmission, and a duration of each of the first PUSCH transmission and the second PUSCH transmission.
