[0018] [Figure 11] Figure 11 shows an embodiment of a partial block diagram of the apparatus based on several implementations of the disclosed technology. [Modes for carrying out the invention]

[0019] (Detailed explanation) The disclosed technology provides implementations and examples of a power control scheme for simultaneous uplink transmission.

[0020] Power control is used to compensate for path loss, overcome shadow fading, and suppress interference by adjusting the transmission power of signals from the UE or base station. Power control can be divided into closed-loop based and open-loop based, depending on whether the transmitter (e.g., UE) adjusts the transmission power based on information from the receiver (base station). Essentially, closed-loop and open-loop power control work together within the NR system. For example, if the UE adjusts the transmission power according to an estimated value of path loss, it is considered open-loop; if the UE adjusts the transmission power according to TPC commands from the base station, it is considered closed-loop.

[0021] In current NR systems, the UE determines the transmission power of the uplink signal based on at least one of the following: target received power, path loss compensation, power control commands, bandwidth, etc. On the other hand, a maximum output power value is defined for different UE classes and cases, and the UE's transmission power is not permitted to exceed the defined value.

[0022] As an example, NR TS38.213 uses a parameter set configuration with index j and a push power control adjustment state with index l, to enable push power P on the active UL BWP b of carrier f of serving cell c. PUSCH,b,f,c (i,j,q d ,l) is determined as follows:

number

[0023] In equation (1), P CMAX,f,c (i) is the maximum output power with respect to the carriers of the serving cell, P O_PUSCH is the target received power configured by the base station, α is the coefficient for path loss compensation, and PL is the index q. d An estimated value of path loss associated with a reference signal, accompanied by Δ TFThis is determined based on the modulation and coding scheme (MCS), and f is a transmission power adjustment command received within the scheduling DCI.

[0024] The determined transmission power of the signal is the maximum value (P CMAX When it exceeds ), the UE is requested to scale it so that it does not exceed the maximum value.

[0025] The maximum output power within a transmission duration is similarly defined, and the transmission duration may refer to the duration of a slot, subslot, frame, or subframe. Therefore, multiple uplink transmissions may be transmitted within the same transmission duration. When the total transmission power of transmissions within a transmission duration exceeds the maximum output power, the UE is required to allocate or scale the transmission power of the transmissions according to priority rules.

[0026] Figure 1 illustrates a schematic diagram showing the power distribution and scaling scheme implemented in response to exceeding the maximum output power within the transmission duration. As shown in Figure 1, power distribution operates one by one based on priority order. If the remaining power is sufficient for the assigned signal, the signal's transmission power does not require scaling. If the remaining power is insufficient for the assigned signal, the signal's transmission power will be scaled, and signals with a lower priority than the assigned signal will be set to zero.

[0027] Recently, multiple transmission point (MTRP) transmission technology has been developing rapidly, with multiple TRPs being implemented by multiple base stations or multiple panels on a single base station. As user equipment has evolved, the number of antennas and panels is increasing, and the types and uses of equipment are becoming more diverse. For example, 5G customer premises equipment (CPE), in-vehicle communication devices, and XR equipment are currently attracting significant attention.

[0028] With low capability, UEs (Underground Equipment) can only transmit one uplink signal (PUSCH, PUCCH, SRS, and PRACH) at a time due to the structure of their radio frequency (RF) handling units. As UEs have evolved, some UEs with higher capability have multiple panels and multiple RF links, which allows the UE to transmit uplink signals simultaneously through multiple panels. UEs that transmit multiple parts of an uplink signal or multiple uplink signals simultaneously through multiple panels may be referred to as STxMP (Single-Track Multi-Purpose) UEs.

[0029] In general, UEs can adjust the transmission power of the transmitted signal, taking into account various considerations such as reducing interference, saving power, and improving reliability. The UE's behavior when the maximum transmission power and maximum output power are exceeded is defined by relevant specifications, e.g., 3GPP®. The maximum output power on a serving cell and the maximum output power per carrier per serving cell within a frequency range are defined in relevant specifications, e.g., 3GPP® TS38.101.

[0030] When an UE has the capability for simultaneous uplink transmission, it must be able to determine the individual or total transmission power of uplink transmissions being transmitted simultaneously within the time domain. Generally, simultaneous transmissions are transmitted through different panels of the UE, and the UE is required to determine the transmission power per individual panel.

[0031] Figure 2 shows an illustrative schematic diagram of simultaneous uplink transmission from multiple panels of a user device in the case of multiple TRPs between cells. As shown in Figure 2, the UE can transmit two uplink signals simultaneously through two panels. The types of uplink signals can be identical, for example, both being push signals, or they can be different from each other. Thus, the disclosed technology can be applied to both cases where the types of uplink signals are different and identical. In another embodiment, the UE can transmit two parts of an uplink signal simultaneously through two panels. In this case, the two parts of the uplink signal can correspond to uplink transmissions.

[0032] In various scenarios, UEs are required to address issues when transmission power exceeds maximum output power, but a unified or equal scaling scheme is used for convenience without flexibility. Various implementations of the disclosed technology provide more flexible transmission power determination and scaling schemes to control the power of transmissions to different TRPs.

[0033] For transmission power determination and power allocation / scaling in the case of STxMP, various implementations of the disclosed technology propose the following features.

[0034] (1) The following two guidelines are considered for determining the transmission power.

[0035] - The transmission power of uplink transmissions from multiple panels is determined together. The total transmission power, associated with multiple power control parameter sets / panels / TCI states, is determined by the UE. The UE determines the value of each component in the determination formula based on the values ​​associated with one or more transmission information.

[0036] - The transmission power for uplink transmissions from multiple panels is determined individually. The UE determines individual values ​​of transmission power associated with each power control parameter set / panel / TCI state.

[0037] (2) The following will be considered regarding the power distribution to the panels when determining the total transmitted power.

[0038] - The UE determines the transmission power of the uplink transmission, which is associated with transmission information, based on at least one message, and the message is associated with at least one piece of transmission information. The UE obtains the association between the transmission information and the message according to the information element in the RRC signaling, the information in the MAC CE, or the indication field in the DCI format.

[0039] (3) When the transmission power exceeds the maximum output power of the carrier component, the following scaling schemes are considered.

[0040] -UE scales the sum of the transmission power of uplink transmissions associated with the panel so as not to exceed the maximum output power. The scaling factor for each uplink transmission is determined based on at least one message.

[0041] -UE indicates that the transmission power of the uplink transmission should not be scaled based on the message from the base station.

[0042] (4) When the transmitted power exceeds the maximum output power during the transmission duration, the following allocation and scaling schemes are considered.

[0043] - The UE determines the priority of uplink transmissions associated with different panels and allocates / scales transmission power according to priority rules. The determination is based on messages from the base station.

[0044] - The UE scales the transmission power of more than one uplink transmission with the same allocation priority. The UE determines the scaling factor based on the message from the base station.

[0063] Various implementations of the disclosed technology provide various approaches to power control, such as power determination and allocation operations for simultaneous uplink transmission. Figure 3 shows an illustrative schematic diagram illustrating power control for simultaneous uplink transmission based on several implementations of the disclosed technology.

[0064] The following features are examples of some aspects of the various approaches proposed by the disclosed technology.

[0065] (1) Determination of transmission power of uplink transmissions that are transmitted with complete or partial overlap in the time domain.

[0066] The UE obtains the association between uplink transmissions and transmission information according to at least one of the following: a power control parameter set (group) index, a panel index, a spatial relationship index, a resource set index, or a TCI state.

[0067] Option 1: In some implementations, the UE determines the total transmission power of overlapping transmissions, which are associated with individual transmission information.

[0068] In some implementations, the UE determines the total transmission power based on at least one message from the base station. The UE obtains an association between transmission information and the message based on RRC signaling, MAC CE, or DCI format. In some implementations, the message comprises at least one of the following: target received power value, TPC command, measured value of path loss associated with PL-RS, modulation and coding scheme, bandwidth, subcarrier spacing, number of physical resources occupied, or PUCCH format. The UE uses at least one of the messages as a power control parameter to determine the transmission power.

[0069] In some implementations, the UE determines the actual value of a power control parameter used to determine the transmission power. For example, when a message has multiple candidate values ​​associated with different transmission information relating to at least one power control parameter, the UE determines to use the mean value of the parameter, the maximum or minimum value of the parameter, one of the parameters indicated by the base station, or a weighted mean value for determining the transmission power. For example, when a message has a TPC command for uplink transmission associated with TRP-1 and a TPC command for uplink transmission associated with TRP-2, the UE determines to use the value relating to the TPC command used to determine the transmission power. For example, the UE may determine to use only one of the values, e.g., the value associated with TRP-1 or the value associated with TRP-2. In another embodiment, the UE may determine to use the mean, maximum, minimum, or weighted mean of those associated with TRP-1 and TRP-2. In some implementations, the weights used to determine the weighted values ​​are included in the message from the base station.

[0070] In some implementations, the UE reports a message to the base station containing information determined by the UE. In some implementations, the reported message may include at least one of the actual values ​​of the power control parameters or a range containing the actual values ​​of the power control parameters. In some implementations, the reported message may further include transmission information (indexes) or flags for the power control parameters associated with the determined information (e.g., indications to represent path loss).

[0071] Option 2: The UE determines the individual transmission power of simultaneous transmissions, which is associated with individual transmission information.

[0072] In some implementations, the UE determines the transmission power based on at least one message from the base station, the message comprising at least one of the following: target received power value, TPC command, measured value of path loss associated with PL-RS, modulation and coding scheme, bandwidth, subcarrier spacing, number of physical resources occupied, or PUCCH format. The message is associated with transmission information. For example, the UE determines the transmission power of a transmission based on a message associated with transmission information index 1 and transmission information index 2, respectively.

[0073] The determination of the transmitted power will be discussed further later in this patent document in relation to Embodiment 1.

[0074] (2) Determination of the transmission power of individual uplink transmissions when the total transmission power of simultaneous transmissions associated with individual transmission information is determined by the UE.

[0075] The UE determines the transmission power of the uplink transmission, which is associated with the transmission information, based on at least one message from the base station, and the message is associated with at least one transmission information. In some implementations, the message from the base station includes at least one of a target received power value, a measured value of path loss associated with PL-RS, bandwidth, the number of occupied physical resources, a PUCCH format, a default coefficient, a coefficient indication, the number of SRS resource ports, or the number of antenna ports of the UE panel.

[0076] In some implementations, the determination is based on the determined total transmission power.

[0077] The determination of the transmission power will be further discussed later in this patent document in relation to Embodiment 2.

[0078] (3) Scaling of the transmission power when it exceeds the maximum output power regarding the carrier component.

[0079] In some implementations, the maximum output power of the UE regarding the carrier component (hereinafter referred to as "P CMAX,f ") is defined. In some implementations, the maximum output power associated with the transmission information (hereinafter referred to as "Pcmax,p") is defined. In some implementations, P CMAX,p is determined by P CMAX,f and a message from the base station associated with the transmission information.

[0080] P CMAX,p is based on P CMAX,f and does not exceed P CMAX,f . In some implementations, the base station transmits a message to the UE, which includes a coefficient "m" for indicating the value of Pcmax,p (e.g., P CMAX,p = m * P CMAX,f ).

[0081] In some implementations, the UE sets the transmission power of the uplink transmission to P CMAX,pScaling will be done so as not to exceed a certain limit.

[0082] In some implementations, the UE determines the total transmission power of simultaneous uplink transmissions as P CMAX,f To prevent exceeding a certain limit, scale the transmission power of at least one uplink transmission associated with a single transmission.

[0083] In some implementations, the UE determines a scaling factor for uplink transmissions that requests transmission power scaling. In some implementations, a common scaling factor is used for all uplink transmissions. In some implementations, the determination of the scaling factor is based on at least one message from the base station. In some implementations, the message from the base station is associated with at least one transmission information. In some implementations, the message from the base station includes at least one of the following: target received power, default factor, or factor indication. In some implementations, the information associated with at least one transmission information includes at least one of the following: target received power value, measured value of path loss associated with PL-RS, bandwidth, number of physical resources occupied, PUCCH format, default factor, factor indication, number of SRS resource ports, or number of antenna ports on the UE panel.

[0084] In some implementations, the base station sends a message to the UE indicating at least one transmission or uplink transmission that does not request transmission power scaling.

[0085] The scaling of transmission power will be discussed further later in this patent document in relation to Embodiment 3.

[0086] (4) Scaling of transmission power when the maximum output power is exceeded within the transmission duration.

[0087] Maximum output power of the UE during the transmission duration (hereinafter referred to as "P CMAX,iA transmission duration (called a "transmission duration") is defined and comprises symbols, slots, subslots, frames, or subframes.

[0088] In some implementations, the UE scales the transmission power of each uplink transmission based on priority rules. Referring back to Figure 1, each uplink transmission has a corresponding priority, and the UE allocates power to the uplink transmissions based on the priority associated with them. The determined total transmission power of the uplink transmissions within the transmission duration is scaled and allocated based on the priority rules to meet the demand for uplink transmissions with higher priority.

[0089] In some implementations, scaling of transmission power may not be necessary. For example, the sum of the determined transmission power of an uplink transmission with a higher priority than one uplink transmission and the transmission power of one uplink transmission is P CMAX,i When it does not exceed a certain value, the UE does not scale the transmission power of an uplink transmission.

[0090] In some implementations, the UE determines that the sum of the determined transmission power of an uplink transmission with a higher priority than that of a certain uplink transmission and the determined transmission power of a certain uplink transmission is P CMAX,i When it exceeds this value, the transmission power of the uplink transmission is scaled.

[0091] In some implementations, the UE scales the transmission power of the uplink transmission to zero when no transmission power can be allocated to the uplink transmission.

[0092] In some implementations, the transmission priority of PUCCH and PUSCH messages carrying the same UCI type, associated with different transmission information, is determined based on messages from the base station. In some implementations, a message comprises at least one of the following: RRC signaling, DCI format, or MAC CE. A message comprises at least one of the following: target received power value, measured path loss associated with PL-RS, bandwidth, number of occupied physical resources, PUCCH format, default coefficient, coefficient indication, number of SRS resource ports, number of antenna ports on the UE panel, or indication of transmission information.

[0093] In some implementations, the UE prioritizes the total transmission power of all uplink transmissions and the transmission power of some uplink transmissions over the maximum output power, P CMAX,i When greater than this value, it scales the transmission power of more than one uplink transmission (a set of uplink transmissions). A set of uplink transmissions is determined to have the same allocation priority.

[0094] In some implementations, the scaling factor for each uplink transmission is determined based on at least one message from the base station, and the message from the base station is associated with at least one transmission information. The message from the base station includes at least one of the following: target received power value, PL-RS associated with measured path loss, bandwidth, number of physical resources occupied, PUCCH format, default factor, factor indication, number of SRS resource ports, number of antenna ports on the UE panel, or an indication of transmission information.

[0095] The scaling of transmission power will be discussed further later in this patent document in connection with Embodiment 4.

[0096] In Embodiments 1-4 discussed below, two uplink transmissions are transmitted simultaneously through multiple panels. The two uplink transmissions are merely examples, and the disclosed technology is not limited to two uplink transmissions.

[0097] Embodiment 1

[0098] In Embodiment 1, the transmission power of uplink transmissions that are transmitted in overlapping manner in the time domain is determined. Based on a message from the base station, the UE determines the transmission power of one or more simultaneous uplink transmissions at once, and the message comprises a plurality of configured power control parameters and other power control parameters obtained or measured by the UE.

[0099] In some implementations, the UE determines the transmitted power based on at least one of the power control parameters. Examples of power control parameters may include at least one of the following: target received power, path loss compensation coefficient, path loss associated with PL-RS, closed-loop power control command, bandwidth, number of physical resources occupied, modulation and coding scheme, or subcarrier spacing.

[0100] In some embodiments, the UE is configured / indicated, individually or commonly, with at least one set of power control parameters for each transmission piece of information. Each set of power control parameters includes at least one of the following: target received power, path loss compensation coefficient, index of a reference signal for path loss measurement, closed-loop power control command, bandwidth, number of physical resources occupied, modulation and coding scheme, or subcarrier spacing. The UE may determine a common or distinct value for at least one of the power control parameters for each transmission piece of information.

[0101] In some embodiments, the UE determines the total transmission power of more than one uplink transmission that should be transmitted simultaneously. The UE determines the value of each parameter in a determination formula based on power control parameters associated with at least one of the transmission pieces of information.

[0102] In some embodiments, the UE receives a message from the base station, which instructs the UE to select a value for a power control parameter to determine the total transmission power. The message can be in RRC signaling, MAC CE, or DCI format. For example, if an information element in RRC signaling includes an indication for the UE to select a value for a power control parameter, and the value of the indication is set to 1, the UE selects a value for the power control parameter associated with the transmission information, with index 1, to determine the transmission power.

[0103] In some embodiments, the UE selects a value for a power control parameter to determine the total transmitted power based on default rules. For example, according to default rules, the UE selects the maximum or minimum value among the values ​​associated with individual transmission information regarding the power control parameter.

[0104] In some embodiments, the UE determines the actual value of a power control parameter, which should be used to determine the total transmitted power. When the UE receives or acquires a power control parameter associated with more than one transmission information, the UE determines the value of the power control parameter based on various rules, such as a weighted average, average, or sum. The weight is indicated by the base station for each value. For example, the UE acquires path loss PL-1 associated with panel 1 and path loss PL-2 associated with panel 2. In some implementations, the UE determines the average of PL-1 and PL-2 as the path loss compensation parameter to determine the total transmitted power.

[0105] In some embodiments, the UE sends a message to the base station during uplink transmission. The message comprises at least one of the following: a selected / determined value of a power control parameter, a value range containing the selected / determined value of the parameter, an index of transmission information associated with the selected / determined value, or a flag of the power control parameter. For example, the UE decides to select a value of path loss measured based on the PL-RS associated with panel-1 in order to determine the total transmission power, and the UE reports to the base station the panel index of panel-1 and the flag of the path loss in transmission for PUSCH.

[0106] In some embodiments, the UE determines the transmission power of each simultaneous uplink transmission separately. In this case, the UE determines the transmission power based on power control parameters associated with the individual transmission information.

[0107] Figure 4 illustrates a transmission power determination scheme in the case of STxMP, based on several implementations of the disclosed technology. Referring to Figure 4, there are two separate transmission information, namely transmission information 1 and transmission information 2. The total transmission power is determined based on the power control parameters associated with transmission information 1 and the power control parameters associated with transmission information 2. The UE is required to handle multiple values ​​for the same power control parameter. For example, with respect to the same power control parameter, e.g., the TPC command, transmission information 1, and transmission information 2 may have different values ​​from each other.

[0108] Embodiment 2

[0109] Embodiment 2 relates to the determination of the transmission power of each uplink transmission, associated with individual transmission information, when the total power transmission is determined by the UE for multiple uplink transmissions. In the description below, the determined total transmission power of an uplink transmission is P t It is shown as follows.

[0110] In some embodiments, the UE determines individual transmission power based on at least one of the power control parameters included in the determination formula. The parameters include at least one of the following: target received power, path loss compensation coefficient, index of a reference signal for path loss measurement, closed-loop power control command, bandwidth, number of physical resources occupied, modulation and coding scheme, or subcarrier spacing. For example, the UE obtains path loss PL-1 associated with panel 1 and path loss PL-2 associated with panel 2. The UE determines that the transmission power of the uplink transmission with respect to panel 1 is P t *(PL-2) / (PL-1+PL-2), where the transmission power of the uplink transmission related to panel-2 is P t Determine that it is *(PL-1) / (PL-1+PL-2).

[0111] In some embodiments, the UE determines individual transmission power based on a message from the base station. The message comprises at least one of the allocation coefficient or the number of SRS resource ports. For example, the UE receives an indication, which is contained within the RRC signaling, with a value m, and the transmission power of the uplink transmission for panel-1 is m*P t Therefore, the transmission power of the uplink transmission related to panel-2 is (1-m)*P t The UE determines that the number of SRS resource ports for uplink transmission associated with panel-1 and panel-2 is a and b, respectively, and the UE determines that the transmission power for uplink transmission associated with panel-1 and panel-2 is Pt*a / (a+b) and Pt*b / (a+b), respectively.

[0112] In some embodiments, the UE determines individual transmission power based on a message, which includes at least one of a default coefficient, coefficient indication, or panel antenna ports. For example, when the antenna ports of panel-1 and panel-2 are N1 and N2, respectively, the UE determines that the transmission power for the uplink transmission with respect to panel-1 is Pt *N1 / (N1+N2), where the transmission power of the uplink transmission related to panel-2 is P t It is determined that *N2 / (N1+N2). In another embodiment, when the default or indicated coefficient is m, the UE determines that the transmission power of the uplink transmission with respect to panel-1 is m*P t Therefore, the transmission power of the uplink transmission related to panel-2 is (1-m)*P t It is determined that this is the case.

[0113] Embodiment 3

[0114] Embodiment 3 provides an example for scaling transmission power when the determined sum of simultaneous uplink transmissions exceeds the maximum output power, where the maximum output power is defined for the carrier component for the serving cell. In the embodiment given below, only a few specific schemes for determining the scaling factor are considered. Those skilled in the art will understand that other schemes can also be applied to determine the scaling factor based on messages from the base station.

[0115] In some embodiments, the UE is defined with the sum of the maximum power per panel and the maximum power per panel equal to the maximum power per panel for the carrier component, and the maximum power per panel is defined based on at least one of the following: a "default coefficient," a "specified coefficient," the "number of antenna ports," a "UE capability value," a set of predefined values, or a table of predefined values. The UE limits the transmission power of an uplink transmission associated with transmission information so as not to exceed the maximum power per panel, and limits the transmission power of another uplink transmission associated with another transmission information so as not to exceed another maximum power per panel.

[0116] Figure 5 illustrates an illustrative schematic of the transmission power when the maximum output power per panel is defined. In Figure 5, the sum of the maximum output powers for panel-1 and panel-2 is equal to the maximum output power for the carrier component. As shown in Figure 5, the determined transmission power of the uplink transmission associated with panel-1 does not exceed the maximum output power for panel-1, and the transmission power of the uplink transmission associated with panel-2 does not exceed the maximum output power for panel-2.

[0117] Figure 6 illustrates an illustrative schematic of transmission power when the maximum output power per panel is not specified, or when the maximum output power per panel is equal to the maximum output power for the carrier component. In some implementations, the UE limits the transmission power of an uplink transmission associated with transmission information so as not to exceed the maximum output power for the carrier component, and the UE limits the transmission power of another uplink transmission associated with different transmission information so as not to exceed the maximum output power for the carrier component.

[0118] Figure 7 illustrates an illustrative schematic of transmission power when the maximum output power per panel is defined. In Figure 7, the sum of the maximum output power for panel-1 and the maximum output power for panel-2 is greater than the maximum output power for the carrier component, and the maximum output power per panel is defined based on at least one of the following: “default coefficient,” “indicated coefficient,” “number of antenna ports,” “UE capability value,” a set of predefined values, or a table of predefined values. In some implementations, when the UE limits the transmission power of an uplink transmission associated with transmission information so as not to exceed the maximum output power for panel-1, the UE further limits the transmission power of another uplink transmission associated with different transmission information so as not to exceed the maximum output power for panel-2.

[0119] In some embodiments, when the total transmission power of uplink transmissions associated with different transmission information exceeds the maximum output power for the carrier component, and the individual transmission power of each uplink transmission falls below the maximum output power for the corresponding transmission information, the UE scales the transmission power of at least one uplink transmission so that the sum of the scaled transmission powers does not exceed the maximum output power for the carrier component.

[0120] In some embodiments, the UE determines a scaling factor for each uplink transmission that requests transmission power scaling. The determination is based on at least one message from the base station, the message is associated with at least one transmission information. The message from the base station may include at least one of the following: target received power value, measured path loss associated with PL-RS, bandwidth, number of physical resources occupied, PUCCH format, default factor, factor indication, number of SRS resource ports, number of antenna ports on the UE panel, or indication of transmission information. For example, the base station indicates to the UE a factor m for panel-1, where the determined transmission powers for uplink transmissions for panel-1 and panel-2 are X and Y, respectively, and the maximum output power for the carrier component is P cmax,f Let's assume that. In the example, UE is P v(mX+Y) cmax,f The scaling is performed so as not to exceed a certain value, where v*m is the scaling factor for the transmission power of the uplink transmission associated with panel-1, and v is the scaling factor for the transmission power of the uplink transmission associated with panel-2. The message from the base station determines the value of m, and the determination of v is at the discretion of the UE.

[0121] In some embodiments, the UE receives or retrieves multiple values ​​of the same type of message, each value associated with transmission information, and the UE determines the respective scaling factors for simultaneous uplink transmissions based on these multiple values. For example, the UE determines that the number of SRS resource ports associated with panel-1 and panel-2 are A and B, respectively, the determined transmission powers for uplink transmissions with respect to panel-1 and panel-2 are X and Y, respectively, and the maximum output power with respect to the carrier component is P cmax,f Get the message that it is. In the example, UE gets v(AX+BY) / (A+B) P cmax,f The scaling is performed so as not to exceed a certain value, where v*A / (A+B) is the scaling factor for the transmission power of the uplink transmission associated with panel-1, and v*B / (A+B) is the scaling factor for the transmission power of the uplink transmission associated with panel-2. Messages from the base station determine the values ​​of A and B, and the determination of v is at the discretion of the UE.

[0122] In some embodiments, the UE determines the same scaling factor for uplink transmissions that require transmission power scaling. For example, the determined transmission powers for simultaneous uplink transmissions with respect to panel-1 and panel-2 are X and Y, respectively, and the maximum output power with respect to the carrier component is P cmax,f Therefore, UE is v(X+Y) P cmax,f The scaling is performed so as not to exceed a certain value, where v is a common scaling factor determined by the UE.

[0123] In some embodiments, the UE receives a message from the base station, the message contains at least one transmission piece of information, and the UE does not scale the transmission power of the uplink transmission associated with the indicated transmission piece of information. For example, the determined transmission powers of the uplink transmission for panel-1 and panel-2 are X and Y, respectively, and the maximum output power for the carrier component is P cmax,fTherefore, the base station indicates to the UE not to scale the transmission power of the transmission associated with panel-2. In this case, the UE sets vX to P cmax,f - The system scales so that it does not exceed Y, where v is the scaling factor. An indication that instructs the UE not to scale the transmission power of an uplink transmission associated with certain transmission information can be implemented with a specific value. For example, in the 3GPP® TS specification, such an indication has a value equal to 1. In some embodiments, the message indicates at least one transmission piece of information, and the UE scales only the transmission power of the uplink transmission associated with the indicated transmission piece of information.

[0124] Embodiment 4

[0125] Embodiment 4 provides an embodiment for scaling transmission power when the determined transmission power exceeds the maximum output power within the transmission duration. The maximum output power is defined to limit the total transmission power of multiple uplink transmissions transmitted within the same transmission duration, and therefore the total transmission power of multiple uplink transmissions is limited not to exceed the maximum output power.

[0126] When the total transmission power for transmissions within the same transmission duration exceeds the maximum output power for that transmission duration, the UE allocates and / or scales the transmission power based on priority rules for the transmissions.

[0127] In some embodiments, for simultaneous uplink transmissions of PUCCH or PUCCH, scheduled by DCI, that carry the same UCI type and have the same priority indication, the UE determines power allocation priority based on a message associated with transmission information. The message from the base station includes at least one of the following: a target received power value, a measured value of path loss associated with PL-RS, the number of SRS resource ports, the number of antenna ports on the UE panel, or an indication of transmission information. For example, the base station instructs the UE to prioritize power allocation for a transmission associated with panel-1. For example, the UE determines that an uplink transmission with a larger transmission power value should have a higher priority than one with a smaller transmission power value.

[0128] In some embodiments, for PUCCH or PUSCH transmissions that carry the same UCI type and have the same priority indication, are scheduled by DCI, and are transmitted simultaneously and associated with different transmission information, the UE simultaneously allocates transmission power to the above transmissions.

[0129] In some embodiments, to allocate transmission power for simultaneous uplink transmissions, the UE scales the transmission power of the uplink transmissions so that the total allocated transmission power does not exceed the maximum output power within the transmission duration. The UE determines the scaling factor for the uplink transmissions based on a message, which comprises at least one of the following: a target received power value, a measured value of path loss associated with the PL-RS, the number of SRS resource ports, the number of antenna ports on the UE panel, a default factor, a factor indication, or the determined transmission power. For example, the determined transmission powers of the transmissions associated with panel-1 and panel-2 are X and Y, respectively, and the base station indicates a factor value a for panel-1 and another factor value b for panel-2, and P cmax,i However, the maximum output power within the transmission duration is P alloHowever, assume that this is the power allocated to uplink transmissions with higher priority. In this case, in the embodiment, the UE sets v(aX+bY) to P cmax,i -P allo The scaling is performed so as not to exceed , where va and vb are scaling factors. In another embodiment, the determined transmission power of the transmission associated with panel-1 and panel-2 are X and Y, respectively, and the base station indicates a target received power value P1 for panel-1 and another value P2 for panel-2, P cmax,i However, the maximum output power within the transmission duration is P allo However, assume that this is the power allocated to uplink transmissions with higher priority. In this case, in the embodiment, the UE sets v(aX+bY) to P cmax,i -P allo Scaling so as not to exceed a certain value, a is equal to P1 / (P1+P2) and b is equal to P2 / (P1+P2).

[0130] Figure 8 illustrates a flowchart showing exemplary wireless communication methods based on several implementations of the disclosed technology. Method 800 includes, in operation 810, receiving a message from a network indicating one or more sets of power control parameters associated with at least one transmission information by a user device scheduled to simultaneously transmit uplink transmissions, which are fully or partially overlapping in the time domain and associated with separate transmission information. Method 800 further includes, in operation 820, determining the transmission power of at least one of the uplink transmissions based on the message.

[0131] In some implementations, the uplink transmission comprises at least one of the following: an uplink signal transmission opportunity, an uplink signal repetition, or an uplink signal comprising PUCCH, PUSCH, SRS, or PRACH; and the transmission information comprises at least one of the following: information grouping one or more reference signals, a reference signal resource set, a PUCCH resource set, panel-related information, a subarray, an antenna group, an antenna port group, a group of antenna ports, a beam group, a beam state, a physical cell index (PCI), TRP-related information, a CORESET pool index, an index of the TCI state at a TCI state code point, a UE capability value, or a UE capability set.

[0132] In some implementations, method 800 further includes obtaining an association between a message and transmission information based on the message by the user device. In some implementations, the determination of transmission power includes determining the total transmission power for an uplink transmission or determining the transmission power for each individual uplink transmission. In some implementations, method 800 further includes determining the actual value of a power control parameter used to determine the total transmission power, the actual value being determined as one of the average, sum, weighted average, or maximum or minimum values ​​of the received values ​​of the power control parameter associated with the individual transmission information.

[0133] In some implementations, method 800 further includes determining individual transmission power based on a plurality of power control parameters associated with individual transmission information. In some implementations, method 800 further includes a user device transmitting a reporting message to the network that includes at least one of the following: the actual value of a power control parameter, an index of transmission information associated with the actual value, or a flag of the actual value of a power control parameter. In some implementations, method 800 further includes allocating total transmission power to each uplink transmission based on a message associated with at least one transmission piece of information.

[0134] In some implementations, determining the transmission power includes limiting the transmission power of an uplink transmission so as not to exceed a maximum output power associated with at least one transmission information. In some implementations, the maximum output power is determined based on a message associated with at least one transmission information. In some implementations, method 800 further includes determining at least one scaling factor for at least one of the uplink transmissions when the total transmission power of the uplink transmissions exceeds the maximum transmission power. In some implementations, the scaling factor is determined based on a message associated with at least one transmission information.

[0135] In some implementations, method 800 further includes receiving a message from the network indicating that the transmission power of the uplink transmission, associated with specific transmission information, does not require scaling. In some implementations, method 800 further includes determining a scaling factor for the transmission power of the uplink transmission, associated with specific transmission information, in order to have a value for skipping scaling of the transmission power of the uplink transmission. In some implementations, the value is 1.

[0136] In some implementations, method 800 further includes determining at least one scaling factor to limit the transmission power of at least one of the uplink transmissions when the total transmission power of an uplink transmission exceeds the maximum output power within the transmission duration. In some implementations, the transmission power of an uplink transmission is scaled based on the priority of the uplink transmission. In some implementations, the priority is determined based on a message associated with at least one transmission information. In some implementations, uplink transmissions carry the same uplink control information (UCI) type but are associated with different transmission information. In some implementations, the transmission power of several uplink transmissions with the same priority is scaled if the sum of the transmission powers of the uplink transmission with the higher priority and several uplink transmissions satisfies a predetermined condition. In some implementations, the scaling factor of an uplink transmission is determined based on a message associated with at least one transmission information.

[0137] Figure 9 illustrates a flowchart showing exemplary wireless communication methods based on several implementations of the disclosed technology. Method 900 includes, in operation 910, transmitting a message to a user device via a network, which includes at least one set of power control parameters. Method 900 further includes, in operation 920, receiving transmissions from the user device via the network, which overlap in the time domain and are associated with separate transmission information, the transmissions having transmission power which is determined and scaled based on a message associated with at least one transmission information so that the transmission power does not exceed a maximum output power.

[0138] In some implementations, method 900 further includes the network receiving a reporting message from a user device that includes at least one of the following: the actual value of a power control parameter, an index of transmission information associated with the actual value, or a flag for the actual value of the power control parameter. In some implementations, the transmission power is determined based on at least one scaling factor for at least one transmission when the total transmission power of a transmission exceeds the maximum output power for the carrier component, and the scaling factor is determined based on the message. In some implementations, method 900 further includes the network transmitting a message to the user device indicating that the transmission power of a particular transmission does not require scaling, associated with specific transmission information. In some implementations, the transmission power of a transmission is scaled based on a scaling factor to limit the transmission power of a transmission when the total transmission power of a transmission exceeds the maximum output power within the transmission duration. In some implementations, the transmission power of a transmission is scaled based on a priority rule, and the priority of a transmission is determined based on a message associated with at least one piece of transmission information. In some implementations, the transmission power of multiple uplink transmissions with the same priority is scaled if the sum of the transmission power of the higher priority transmission and the transmission power of the multiple uplink transmissions satisfies a predetermined condition.

[0139] In the implementation discussed above in relation to Figures 8 and 9, the power control parameters include at least one of the following: target received power value, transmission power control (TPC) command, index of a reference signal for path loss measurement, modulation and coding scheme, number of physical resources occupied, channel format, or bandwidth; and the message further includes at least one of the following: determined transmission power, weight indication, default coefficient, coefficient indication, transmission information indication, measured value of path loss associated with PL-RS, number of SRS resource ports, number of antenna ports, UE capability value, predefined value, or index of a predefined set of values.
