[0027] In one embodiment, the terminal device may be connected to a first network device and a second network device. One of the first and second network devices may be a master node, and the other may be a secondary node. The first and second network devices may use different radio access technologies (RATs). In one embodiment, the first network device may be a first RAT device, and the second network device may be a second RAT device. In one embodiment, the first RAT device is an eNB, and the second RAT device is a gNB. Information related to different RATs may be transmitted to the terminal device from at least one of the first or second network devices. In one embodiment, the first information may be transmitted from the first network device to the terminal device, and the second information may be transmitted directly from the second network device to the terminal device or via the first network device. In one embodiment, information regarding the settings of the terminal device set by the second network device may be transmitted from the second network device via the first network device. Information regarding the reconfiguration of a terminal device set by the second network device may be transmitted directly from the second network device to the terminal device, or transmitted via the first network device.

[0028] As used herein, the singular forms “a / an” and “the” are intended to include the plural unless the context explicitly indicates otherwise. The term “including” and its variations are interpreted as an open term meaning “including, but not limited to.” The term “based on” is interpreted as “at least partially based on.” The terms “one embodiment” and “a certain embodiment” are interpreted as “at least one embodiment.” The term “another embodiment” is interpreted as “at least one other embodiment.” The terms “first” and “second” may refer to different or the same subject. The following may include other explicit and implicit definitions.

[0029] In some examples, values, procedures, or devices are referred to as “best,” “worst,” “highest,” “minimum,” “maximum,” etc. Such descriptions are intended to show that a choice can be made from among many functional options being used, and it will be understood that such a choice does not need to be better, smaller, higher, or more desirable than the other options.

[0030] As is known, the UE can set its maximum output power. The set maximum output power P of the UE relative to the carrier f of the serving cell c. CMAX,f,c This may be defined as a reference point available for a given transmitter branch, corresponding to the reference point for upper-layer filtered Reference Signal Receiving Power (RSRP) measurements. The set maximum UE output power P relative to the carrier f of serving cell c. CMAX,f,c This corresponds to the measured peak EIRP (Effective Isotropic Radiated Power) P UMAX,f,c It should be set such that in equation (1) it is within the following range, P Powerclass +DP IBE -MAX(MAX(MPR f,c A-MPR f,c,)+ΔMB P,n ,P-MPR f,c )-MAX{T(MAX(MPR f,c ,A-MPR f,c ,)),T(P-MPR f,c )}≦P UMAX,f,c ≦EIRP max (1) On the one hand, the corresponding measured total radiated power P TMAX,f,c is limited by Equation (2), P TMAX,f,c ≦TRP max (2) where P powerclass represents the UE minimum peak effective isotropic radiated power (EIRP), EIRP max represents the applicable maximum EIRP, MPR f,c represents the maximum output power reduction for carrier f of serving cell c, A-MPR f,c represents the additional maximum output power reduction for carrier f of serving cell c, ΔMB p,n represents the peak EIRP relaxation, P-MPR f,c represents the power management UE maximum power reduction for carrier f of serving cell c, T(ΔP) represents the tolerance value T(ΔP) for applicable values of ΔP, and TRP max represents the maximum TRP for the UE power class. The UE declares that it supports mpr-PowerBoost-FR2-r16, the UL transmission is QPSK, and when MPR t,c = 0 and NS_200 is applied and the network configures the UE to operate with mpr-PowerBoost-FR2-r16, DP IBE is 1.0 dB, otherwise DP IBE is 0.0 dB. The requirement is verified in the beam peak direction. mpr-PowerBoost-FR2-r16 indicates whether the UE is permitted to increase the uplink transmission power by suspending the in-band emission (IBE) requirement.

[0031] It has been agreed that the per-panel power limit and the total power limit per UE for STxMP should apply to the same UE. The variation between beams of different panels transmitted simultaneously may be large or small, and therefore, even if the EIRP requirements are the same for each panel, the maximum UE output power per panel may differ.

[0032] With this in mind, embodiments of the present disclosure provide a communication solution for UL PC to overcome the above or other potential problems. In this solution, a terminal device determines the beamset for STxMP. Based on the beamset information, the terminal device determines power limiting information for STxMP and performs STxMP based on the power limiting information. In this way, a suitable UL PC for STxMP may be realized. Quality of UL transmission may be ensured by guaranteeing the highest possible transmit power while meeting the requirements for maximum EIRP.

[0035] Figure 1A shows an exemplary communication network 100A that can implement embodiments of the present disclosure. The communication network 100A includes a network device 110-1 and optionally a network device 110-2 (collectively or individually referred to as network devices 110). The network devices 110 can provide services to terminal devices 120. For convenience of explanation, network device 110-1 is referred to as the first network device 110-1, and network device 110-2 is referred to as the second network device 110-2. Furthermore, the first network device 110-1 and the second network device 110-2 can communicate with each other.

[0036] In the communication network 100A, the link from network device 110 (for example, the first network device 110-1 or the second network device 110-2) to terminal device 120 is called a downlink, and the link from terminal device 120 to network device 110 (for example, the first network device 110-1 or the second network device 110-2) is called an uplink. In a downlink, the first network device 110-1 or the second network device 110-2 is a Tx device (or transmitter), and terminal device 120 is a receiving (Rx) device (or receiver). In an uplink, terminal device 120 is a transmitting Tx device (or transmitter), and the first network device 110-1 or the second network device 110-2 is an Rx device (or receiver).

[0037] In some embodiments, the network device 110 and the terminal device 120 may communicate via a direct link / channel.

[0038] In some embodiments, the terminal device 120 may be deployed with a plurality of panels. As shown in Figure 1A, the terminal device 120 is deployed with panels 125-1 and 125-2. Hereinafter, panels 125-1 and 125-2 may be referred to as the first panel 125-1 and the second panel 125-2, respectively.

[0039] In some embodiments, the first panel 125-1 and the second panel 125-2 correspond to different sets of antenna ports / antenna elements / antenna arrays. As one specific example, the first panel 125-1 corresponds to a first set of antenna ports, and the second panel 125-2 corresponds to a second set of antenna ports. In some embodiments, panels 125-1 and 125-2 may correspond to different sets of capability values, respectively. In some embodiments, panels 125-1 and 125-2 may correspond to different sets of RS resources, respectively. In some embodiments, the RS resource set may be an SRS resource set. Each resource set may contain one or more resources.

[0040] In the communication network 100A, PUSCH STxMP may be supported. Specifically, terminal device 120 may perform PUSCH on both panels 125-1 and 125-2 simultaneously.

[0041] In some embodiments, MTRP transmission may also be supported. As shown in Figure 1A, the terminal device 120 may communicate with two TRPs, namely TRP 130-1 and 130-2 (collectively or individually referred to as TRP 130). For convenience of explanation, TRP 130-1 is referred to as the first TRP 130-1, and TRP 130-2 is referred to as the second TRP 130-2.

[0042] Furthermore, to support MTRP and / or multi-panel, the network device 110 may be equipped with one or more TRPs. For example, the network device 110 may be coupled with multiple TRPs at different geographic locations to achieve better coverage. In one specific exemplary embodiment, the first network device 110-1 is equipped with a first TRP 130-1 and a second TRP 130-2. Alternatively, in another specific exemplary embodiment, the first network device 110-1 and the second network device 110-2 are equipped with a first TRP 130-1 and a second TRP 130-2, respectively.

[0043] In some embodiments, the first TRP 130-1 and the second TRP 130-2 are associated with different control resource set pools (CORESET pools). For example, the first TRP 130-1 is associated with the first control resource set pool, and the second TRP 130-2 is associated with the second control resource set pool.

[0044] Furthermore, both single TRP mode transmission and MTRP transmission may be supported by the specific example in Figure 1A. Specifically, in single TRP mode, terminal device 120 communicates with the network via the first TRP 130-1 / second TRP 130-2. Alternatively, in MTRP mode, terminal device 120 communicates with the network via both the first TRP 130-1 and the second TRP 130-2.

[0045] As one specific exemplary embodiment, during PUSCH STxMP, terminal device 120 communicates with a first TRP 130-1 via panel 125-1 and simultaneously communicates with a second TRP 130-2 via panel 125-2.

[0046] Furthermore, the network device 110 may provide one or more serving cells, and the first TRP 130-1 and the second TRP 130-2 may be contained in the same serving cell or in different serving cells. In other words, both inter-cell transmission and intra-cell transmission are supported by the specific example in Figure 1A.

[0047] Figure 1B shows an exemplary scenario of a communication network 100A as shown in Figure 1A. In the specific example in Figure 1B, the first TRP 130-1 and the second TRP 130-2 are contained within the same serving cell 140. In this case, MTRP transmissions are performed as intra-cell transmissions.

[0048] Figure 1C shows another exemplary scenario of the communication network 100A as shown in Figure 1A. In the specific example of Figure 1C, the first TRP 130-1 and the second TRP 130-2 are contained within different serving cells 140-1 and 140-2. In this case, MTRP transmission is performed as inter-cell transmission.

[0049] Communication in communication network 100A may comply with any appropriate standard, including but not limited to Long Term Evolution (LTE), LTE-Evolution, LTE-Advanced (LTE-A), Wideband Code Division Multiple Access (WCDMA), Code Division Multiple Access (CDMA), and Global System for Mobile Communication (GSM). Furthermore, communication may be performed in accordance with any generation of communication protocol that is currently known or will be developed in the future. Examples of communication protocols include, but are not limited to, first generation (1G), second generation (2G), 2.5G, 2.75G, third generation (3G), fourth generation (4G), 4.5G, fifth generation (5G), 5.5G, 5G-Advanced Network, or sixth generation (6G) communication protocols.

[0050] The number of elements shown in Figures 1A to 1C (i.e., terminal devices 120, panels 125, network devices 110, TRP 130, cells 140), as well as their connections and types, are for illustrative purposes only and should not be considered as limitations. The communication network 100A may include any suitable number of elements adapted to implement embodiments of the present disclosure.

[0051] In some scenarios, the panels may beamform in the same or similar directions. In some scenarios, the panels may beamform in different directions. Figure 2 is a schematic diagram 200 showing an example of a beamset for panels on which embodiments of the present disclosure can be carried out. As shown in Example 210 of Figure 2, the direction of beam 1 of panel 1 and the direction of beam 2 of panel 2 are approximately opposite. As shown in Example 220 of Figure 2, the direction of beam 1 of panel 1 and the direction of beam 2 of panel 2 are similar.

[0052] EIRP is defined per UE, not per panel. The EIRP measured when two panels are beamforming in the same or similar directions may be higher than the EIRP measured when two panels are beamforming in different directions. In other words, the maximum power output per panel may differ. For example, in Example 210, a higher maximum power output per panel or beam may be assumed. In Example 220, a lower maximum power output per panel or beam may be assumed.

[0053] With this in mind, embodiments of the present disclosure provide a communication solution for UL PC to optimize UL PC for STxMP. This solution is described below with reference to Figures 3 and 4. Exemplary implementation of UL PC for STxMP

[0054] Figure 3 is a schematic diagram showing a communication process 300 according to some exemplary embodiments of the present disclosure. For convenience of explanation, the process will be described with reference to Figures 1A to 1C.

[0055] Process 300 may involve a terminal device 120, a network device 110 (either or both of the first network device 110-1 and the second network device 110-2), and optionally a TRP 130 (including the first TRP 130-1 and the second TRP 130-2). In other words, the implementation of some embodiments does not depend on TRP 130. The terminal device 120 may be deployed with a first panel 125-1 and a second panel 125-2. Furthermore, the first panel 125-1 corresponds to a first set of antenna ports, and the second panel 125-2 corresponds to a second set of antenna ports.

[0056] Furthermore, the first TRP 130-1 is connected to the first network device 110-1, and the second TRP 130-2 is connected to the first network device 110-1 / second network device 110-2. In addition, the first TRP 130-1 and the second TRP may be located in the same serving cell or in different serving cells.

[0057] In the following text, several embodiments of the present disclosure are described with reference to two TRPs and two panels, but these embodiments are for illustrative purposes only and are intended to help those skilled in the art to understand and implement the present disclosure without implying any limitation on the scope of the present disclosure. It should be understood that the present disclosure as described herein can be implemented in a variety of ways other than those described below.

[0058] Furthermore, it should be understood that the operation of terminal device 120 and network device 110 should be coordinated. In other words, network device 110 and terminal device 120 should have a common understanding of configuration, parameters, etc. Such a common understanding may be achieved through any appropriate interaction between network device 110 and terminal device 120, or by both network device 110 and terminal device 120 applying the same rules / policies. In the following, some operations are described from the perspective of terminal device 120, but it should be understood that the corresponding operations should be performed by network device 110. Similarly, some operations are described from the perspective of network device 110, but it should be understood that the corresponding operations should be performed by terminal device 120. For brevity, some of the same or similar content has been omitted here.

[0059] Furthermore, in the following description, several interactions (e.g., exchange of capability-related information, resource / transmission configuration / scheduling / activation, etc.) are performed between the terminal device 120 and the network device 110. It should be understood that these interactions may be implemented using either a single signaling / message or multiple signaling / messages, including system information, Radio Resource Control (RRC) messages, DCI, Uplink Control Information (UCI), MAC CE, etc. This disclosure is not limited in this respect.

[0060] In some embodiments, one or more interactions may be specific to a particular panel, TRP, capability value, CORESET, etc. Thus, PUSCH STxMP may be flexibly configured or activated.

[0061] Furthermore, while functions / operations are described individually in certain exemplary embodiments, it should be understood that these functions / operations described in different exemplary embodiments may be used in any suitable combination unless explicitly stated otherwise.

[0062] Referring to Figure 3, the terminal device 120 may also transfer (310) UE capability information to the network device 110. For example, the network device 110 may send RRC settings related to UE capability reporting to the terminal device 120. Based on the RRC settings, the terminal device 120 may report its own capabilities to the network device 110.

[0063] In some embodiments, the capability of the terminal device 120 may include information on whether the terminal device 120 supports power limiting information for the beam. In some embodiments, the power limiting information may indicate the maximum output power. In some embodiments, the power limiting information may indicate the maximum power reduction (MPR). In some embodiments, the power limiting information may indicate the maximum permitted emission (MPE). It should be understood that any combination of this information is also feasible.

[0064] In some embodiments, the capabilities of the terminal device 120 may include information on whether the terminal device 120 supports the maximum output power (denoted as Pcmax) per panel or beam. For example, the capabilities of the terminal device 120 may include information on whether the terminal device 120 supports Pcmax1 for panel 125-1 and Pcmax2 for panel 125-2 in order to calculate the Tx power of the terminal device 120. For example, P CMAX,f,c,t It may be assumed that t represents a panel / beam. In some embodiments, the capability of the terminal device 120 is that the terminal device 120 has the number of beams in the beamset (i.e., the number of panels) and reference power limiting information (e.g., P CMAX,f,c ) may include information supporting the determination of power limiting information for beams within a beamset based on the following: For example, 1 / NP CMAX,f,c This is assumed to be per panel, where N represents the number of panels used for transmission. In some embodiments, the capability of the terminal device 120 is that the terminal device 120 can transmit reference power limit information (e.g., P CMAX,f,c ) and the beam scaling factor may include information on whether it supports determining power limiting information for beams in a beamset. For example, beta 1 * P CMAX,f,c and Beta 2 * P CMAX,f,cThese are assumed for panel 1 and panel 2, respectively, where β1 represents the scaling factor of beam 1 of panel 1 and β2 represents the scaling factor of beam 2 of panel 2. In some embodiments, β1 * P CMAX,f,c and Beta 2 * P CMAX,f,c The sum is P CMAX,f,c It may be greater than or equal to it.

[0065] In other words, the capabilities of terminal device 120 may include information on whether terminal device 120 supports per beam or per TCI Pcmax.

Alternatively, the capabilities of terminal device 120 may include information on whether terminal device 120 supports a number of Pcmax for STxMP.

[0066] In some embodiments, the capabilities of terminal device 120 may include information on whether terminal device 120 supports power limiting information specific to STxMP. For example, the capabilities of terminal device 120 may include information on whether terminal device 120 supports additional Pcmax for STxMP. That is, for UL multi-input multi-output (MIMO) transmission on a single panel, P CMAX,f,c This may be assumed. When using UL STxMP, an additional Pcmax (e.g., P CMAX,f,c,STxMP ) may be assumed. In some embodiments, P CMAX,f,c,STxMP This may apply to the total power of all panels used in STxMP. In some embodiments, P CMAX,f,c,STxMP This may be applied to each panel used in STxMP.

[0067] In some embodiments, the capabilities of terminal device 120 may include information on whether terminal device 120 supports the same power limiting information for STxMP and single-panel transmissions. For example, the capabilities of terminal device 120 may include information on whether terminal device 120 supports the same Pcmax for STxMP and other single-panel UL transmissions. For example, to calculate the Tx power of terminal device 120, regardless of the UL scheme, P CMAX,f,c This can be assumed.

[0068] In some embodiments, the capabilities of the terminal device 120 may include information on whether the terminal device 120 supports MPR per UE, per beam, or per panel. In some embodiments, the capabilities of the terminal device 120 may include information on whether the terminal device 120 supports MPE per UE, per beam, or per panel. In some embodiments, the capabilities of the terminal device 120 may include information on whether the terminal device 120 supports additional MPR for STxMP. In some embodiments, the capabilities of the terminal device 120 may include information on whether the terminal device 120 supports additional MPE for STxMP. In some embodiments, the additional MPE for STxMP may be applied to the total power reduction of all panels used in STxMP. In some embodiments, the additional MPE for STxMP may be applied to the power reduction of each panel used in STxMP. In some embodiments, the capabilities of the terminal device 120 may include information on whether the terminal device 120 supports the same MPR for STxMP and other single-panel UL transmissions. In some embodiments, the capabilities of the terminal device 120 may include information on whether the terminal device 120 supports the same MPE for STxMP and other single-panel UL transmissions.

[0069] Based on the capabilities of the terminal device 120, the network device 110 may configure one or more of the Pcmax assumption, MPR assumption, and MPE assumption applicable to the terminal device 120.

[0070] In some embodiments, the capabilities of terminal device 120 may include information regarding reporting power limit information. In some embodiments, this includes information on whether terminal device 120 supports CSI reporting that includes power limit information. In some embodiments, the capabilities of terminal device 120 may include information on whether terminal device 120 supports reporting power limit information in association with a set of SRIs. In some embodiments, the capabilities of terminal device 120 may include information on whether terminal device 120 supports reporting power limit information in association with a set of TCI states. In some embodiments, the capabilities of terminal device 120 may include information on whether terminal device 120 supports PHR that includes power limit information for STxMP. It should be understood that any combination of the above capabilities is also achievable.

[0071] Continuing to refer to Figure 3, the network device 110 may send an instruction to the terminal device 120 to enable STxMP (320). In the case of STxMP, the terminal device 120 may determine the beamset for STxMP, i.e., the set of beams corresponding to the panels of the terminal device 120 that are transmitted simultaneously (330). In some embodiments, the terminal device 120 may receive a set of DL RS from the network device 110. Based on the measurement of the set of DL RS, the terminal device 120 may determine the beamset for STxMP.

[0072] In some embodiments, the terminal device 120 may transmit a set of UL RS to the network device 110. The network device 110 may measure the set of UL RS and determine the beamset for STxMP based on the measurement results. The network device 110 may instruct the terminal device 120 on the beamset. Thus, the terminal device 120 may determine the beamset based on the instructions from the network device 110.

[0073] Continuing to refer to Figure 3, the terminal device 120 may determine power limiting information for STxMP (340) based on the beamset information. In some embodiments, the beamset information may include the direction of the beams within the beamset. In some embodiments, the beamset information may include the gain of the beams within the beamset. In some embodiments, the beamset information may include the width of the beams within the beamset. In some embodiments, the beamset information may include RSPR or path loss corresponding to the beams within the beamset. It should be understood that any combination of the above information is also feasible.

[0074] Based on the beamset information, the terminal device 120 may determine appropriate power limiting information for STxMP. In some embodiments, the terminal device 120 may determine beam- or panel-specific power limiting information for STxMP. For example, if the beamset includes a first beam and a second beam, the terminal device 120 may determine first power limiting information for the first beam and second power limiting information for the second beam, for example, the terminal device 120 may determine P CMAX,f,c,t We may assume that t represents a panel / beam.

[0075] In some embodiments, the terminal device 120 provides reference power limit information (e.g., P CMAX,f,c The terminal device 120 may determine the maximum output power of each panel as 1 / NP and, based on the number of beams in the beamset and the reference power limit information, determine the power limit information for the beams in the beamset. For example, the terminal device 120 may determine the maximum output power of each panel as 1 / NP. CMAX,f,c We may decide on the number of beams, where N represents the number of beams.

[0076] In some embodiments, the terminal device 120 provides reference power limit information (e.g., P CMAX,f,c) may be determined, and power limit information for the beams in the beamset may be determined based on the reference power limit information and the beam scaling coefficient. For example, the terminal device 120 may determine beta 1 as the maximum output power of panel 1 and panel 2. * P CMAX,f,c and Beta 2 * P CMAX,f,c The scaling coefficients may be determined as follows: β1 represents the scaling coefficient of beam 1 of panel 1, and β2 represents the scaling coefficient of beam 2 of panel 2.

[0077] In some embodiments, the terminal device 120 may determine power limiting information specific to STxMP as power limiting information for the beamset. For example, the terminal device 120 may determine P as the total maximum output power of all beams in the beamset. CMAX,f,c,STxMP In some alternative embodiments, P CMAX,f,c,STxMP This may be applied to each panel used in STxMP.

[0078] In some embodiments, the terminal device 120 may determine the same power limit information for STxMP and single-panel transmissions. In some embodiments, the terminal device 120 may determine reference power limit information for the terminal device 120 (e.g., P CMAX,f,c The following may be determined: the reference power limit information may be determined as power limit information for each beam in the beamset (e.g., each beam).

[0079] Continuing to refer to Figure 3, the terminal device 120 may perform STxMP (350) based on the determined power limit information. In some embodiments where two panels are used for STxMP, the terminal device 120 may determine a first Tx power for the first channel or RS based on the determined power limit information, and a second Tx power for the second channel or RS based on the determined power limit information and the first Tx power. The terminal device 120 may simultaneously transmit the first channel or RS at the first Tx power and the second channel or RS at the second Tx power.

[0080] Continuing to refer to Figure 3, the terminal device 120 may transmit (360) the determined power limit information to the network device 110. In this way, the terminal device 120 may report the power limit information for STxMP to the network. In some embodiments, reporting the power limit information may be done before STxMP is executed. In some embodiments, reporting the power limit information may be done after STxMP is executed.

[0081] In some embodiments, the terminal device 120 may transmit its capability, including power limiting information. In other words, the terminal device 120 may transmit power limiting information in the UE capability report. For example, as power limiting information associated with the maximum output power, depending on different Pcmax assumptions, P CMAX,f,c,t N, scaling factor, or P CMAX,f,c,STxMP It may be reported.

[0082] In some embodiments, the terminal device 120 may transmit power limiting information in the CSI report. In this way, power limiting information for STxMP may be reported in a more dynamic manner. Depending on the selection of the UL beam, the power limiting information (e.g., maximum output power assumption) may differ.

[0083] In some embodiments, the network device 110 may set beam reporting quantities and resources for beam measurement and reporting, and the terminal device 120 may transmit power limiting information in the CSI report based on these settings. In some embodiments, the terminal device 120 may report information for beamsets and information on power limiting for beamsets. The granularity of the reports may vary.

[0084] For example, a Pcmax is assumed for each UE. In this case, the terminal device 120 may report information on whether the beams in the beamset can transmit simultaneously through the same Pcmax. For example, the information may be indicated via a 1-bit or 2-bit indicator. In this way, a high level of reporting may be achieved. In another example, the scaling factors of the beams in the beamset (e.g., beta1, beta2, etc.) may be reported. In this way, reporting with finer granularity may be achieved.

[0085] In some embodiments, the terminal device 120 may transmit group-based beam reports including power limiting information. In some embodiments, the network device 110 may configure group-based beam reports for STxMP to report power limiting information. In some embodiments, based on the capabilities of the terminal device 120, the network device 110 may configure whether it can simultaneously receive reported DL RS corresponding to beams in a beamset.

[0086] In some embodiments, group-based beam reporting may include indicators of power limiting information. In some embodiments, the indicators may be per resource group. In some embodiments, the power limiting information may be associated with beamsets. For example, an exemplary group-based beam reporting may be configured as shown in Table 1. TIFF2026522439000002.tif141161

[0087] In the context of this disclosure, the beamsets for STxMP are assumed to correspond to CRI / SSBRI #1 and #2. It should be understood that reporting four resource groups is merely an example, and the number of resource groups may be any appropriate number depending on the network configuration.

[0088] As shown in Table 1, the field "Indicator for the first resource group" indicates power limit information for CRI / SSBRI #1 and #2 of the first resource group. The field "Indicator for the second resource group" indicates power limit information for CRI / SSBRI #1 and #2 of the second resource group. The field "Indicator for the third resource group" indicates power limit information for CRI / SSBRI #1 and #2 of the third resource group. The field "Indicator for the fourth resource group" indicates power limit information for CRI / SSBRI #1 and #2 of the fourth resource group.

[0089] In some embodiments, power limiting information may be associated with beams within a beamset. For example, an exemplary group-based beam report may be configured as shown in Table 2. TIFF2026522439000003.tif153168

[0090] As shown in Table 2, the field "Indicator for CRI / SSBRI#1 of the first resource group" indicates power limit information for CRI / SSBRI#1 of the first resource group. The field "Indicator for CRI / SSBRI#2 of the first resource group" indicates power limit information for CRI / SSBRI#2 of the first resource group. The field "Indicator for CRI / SSBRI#1 of the second resource group" indicates power limit information for CRI / SSBRI#1 of the second resource group. The field "Indicator for CRI / SSBRI#2 of the second resource group" indicates power limit information for CRI / SSBRI#2 of the second resource group. The field "Indicator for CRI / SSBRI#1 of the third resource group" indicates power limit information for CRI / SSBRI#1 of the third resource group. The field "Indicator for CRI / SSBRI#2 of the third resource group" indicates power limit information for CRI / SSBRI#2 of the third resource group. The field "Indicator for CRI / SSBRI#1 of the fourth resource group" shows power limit information for CRI / SSBRI#1 of the fourth resource group. The field "Indicator for CRI / SSBRI#2 of the fourth resource group" shows power limit information for CRI / SSBRI#2 of the fourth resource group.

[0091] In some alternative or additional embodiments, the indicator may be per group-based beam report rather than per resource group. In some alternative or additional embodiments, the scaling factor may also be reported per beam (i.e., per CRI / SSBRI).

[0092] In some alternative or additional embodiments, the bit length of the power limit information indicator may depend on the number of supported assumptions. For example, if only two of the maximum power assumptions are supported, there may be one bit per resource group.

[0093] In some embodiments, when group-based beam reporting is configured to report UL beam pairs for STxMP, RSRP and differential RSRP-related information may not be reported, as they are intended to indicate the UL beam pair. This may save signaling overhead.

[0094] In some embodiments, when group-based beam reporting is configured to report UL beam pairs for STxMP, RSRP and differential RSRP-related information may be replaced with path loss and differential path loss information. In this way, signaling overhead may be saved.

[0095] In some embodiments, when group-based beam reporting is configured to report UL beam pairs for STxMP, RSRP and differential RSRP-related information may be replaced with Pcmax information. In this way, signaling overhead may be saved.

[0096] While the above examples are described in relation to RSRP reporting, please note that this disclosure is not limited to this, and that signal-to-interference plus noise ratio (SINR) reporting is also possible.

[0097] In some embodiments, the terminal device 120 may transmit a panel information report (i.e., a capability index report) that includes power limit information. In some embodiments, the network device 110 may configure the capability index report for STxMP to report power limit information. In some embodiments, based on the capabilities of the terminal device 120, the network device 110 may configure whether it can simultaneously receive reported DL RS corresponding to different capability indices.

[0098] In some embodiments, the capability index report may include an indicator of power limit information. In some embodiments, the indicator may be per beamset (i.e., per panel). In some embodiments, the power limit information may be associated with a panel. For example, an exemplary capability index report may be configured as shown in Table 3. TIFF2026522439000004.tif90161

[0099] As shown in Table 3, the field "Indicator for the first set" indicates power limit information for beamset 1 of panel 1. Beamset 1 includes the beams of panel 1 and panel 2. The field "Indicator for the second set" indicates power limit information for beamset 2 of panel 2. Beamset 2 includes the beams of panel 1 and panel 2. Note that sets of UL beams corresponding to different capability indices may be transmitted simultaneously.

[0100] In some embodiments, power limiting information may be associated with the panel beams. For example, an exemplary capability index report may be set up as shown in Table 4. TIFF2026522439000005.tif101161

[0101] As shown in Table 4, the field "CRI / SSBRI#1 Indicator" indicates power limit information for CRI / SSBRI#1. The field "CRI / SSBRI#2 Indicator" indicates power limit information for CRI / SSBRI#2. The field "CRI / SSBRI#3 Indicator" indicates power limit information for CRI / SSBRI#3. The field "CRI / SSBRI#4 Indicator" indicates power limit information for CRI / SSBRI#4.

[0102] In some alternative or additional embodiments, the indicator may be per capability index report rather than per beamset. In some alternative or additional embodiments, the scaling factor may also be reported per beam (i.e., per CRI / SSBRI).

[0103] In some alternative or additional embodiments, the bit length of the power limit information indicator may depend on the number of supported assumptions. For example, if only two of the maximum power assumptions are supported, there may be one bit per beamset.

[0104] In some embodiments, when capability index reporting is configured to report UL beam pairs for STxMP, RSRP and differential RSRP-related information may not be reported, as they are intended to indicate UL beam pairs. This may save signaling overhead.

[0105] In some embodiments, when capability index reporting is configured to report UL beam pairs for STxMP, RSRP and differential RSRP-related information may be replaced with path loss and different path loss information. In this way, signaling overhead may be saved.

[0106] In some embodiments, when capability index reporting is configured to report UL beam pairs for STxMP, RSRP and differential RSRP-related information may be replaced with Pcmax information. In this way, signaling overhead may be saved.

[0107] While the above examples are described in relation to RSRP reporting, please note that this disclosure is not limited to this and SINR reporting is also feasible.

[0108] In some embodiments, the terminal device 120 may transmit power limit information associated with a set of SRIs (i.e., a combination of SRIs). The set of SRIs corresponds to a beamset for STxMP. In other words, based on the transmitted SRS, the terminal device 120 may report supported SRI combinations and associated power limit information for STxMP.

[0109] In some embodiments, power limiting information associated with a set of SRIs may be transmitted via RRC signaling. In some embodiments, power limiting information associated with a set of SRIs may be transmitted via MAC CE. In some embodiments, power limiting information associated with a set of SRIs may be transmitted via UCI. In some embodiments, the scaling factors of the beams in the beamset may also be reported.

[0110] In some embodiments, for a given power assumption, supported SRI combinations may be reported. For example, SRI combinations may be {SRS Resource Set 1 SRS Resource 1, SRS Resource Set 2 SRS Resource 2}, {SRS Resource Set 1 SRS Resource 3, SRS Resource Set 2 SRS Resource 4}, with the same Pcmax. That is, UL beams corresponding to SRI1 / 3 from SRS Resource Set 1 and SRI2 / 4 from SRS Resource Set 2 can be used for STxMP, with the maximum output power of each beam being Pcmax.

[0111] Alternatively, or further, the terminal device 120 may transmit power limit information that is not associated with any further set of SRIs. In other words, for a given power assumption, unsupported SRI combinations may be reported.

[0112] In some embodiments, supported power assumptions may be reported for a given SRI combination. Alternatively, or further, unsupported power assumptions may be reported for a given SRI combination.

[0113] In some embodiments, the terminal device 120 may transmit power limit information associated with a set of TCI states. In other words, based on the activated or set TCI state / TCI state combination, the terminal device 120 may report a set of TCI states (i.e., a combination of TCI states) and associated power limit information for STxMP. Thus, the set or activated TCI state / TCI state combination may reflect a network selection of UL beam combinations, and the terminal device 120 may further select or report power assumptions for some or all of these UL beam combinations.

[0114] In some embodiments, power limit information associated with a set of TCI states may be transmitted via RRC signaling. In some embodiments, power limit information associated with a set of TCI states may be transmitted via MAC CE. In some embodiments, power limit information associated with a set of TCI states may be transmitted via UCI. In some embodiments, the scaling factor of the beams in the beamset may also be reported.

[0115] In some embodiments, for a given power assumption, the supported combinations of TCI states may be reported. For example, the combinations of TCI states may be {TCI state 1, TCI state 2}, {TCI state 3, TCI state 4}, with the same Pcmax. That is, UL beams corresponding to TCI states 1 / 3 and TCI states 2 / 4 can be used for STxMP, with the maximum output power of each beam being Pcmax. In another example, the combination of TCI states may be TCI code point 000, TCI code point 001, with the same Pcmax. That is, UL beams corresponding to TCI code points 000 and 001 can be used for STxMP, with the maximum output power of each beam being Pcmax. In yet another example, the combination of TCI states may be the combination of TCI states initially activated by MAC CE, with the same Pcmax. That is, UL beams corresponding to the combination of TCI states initially activated by MAC CE can be used for STxMP, with the maximum output power of each beam being Pcmax.

[0116] Alternatively, or further, the terminal device 120 may transmit power limit information that is not associated with any further set of TCI states. In other words, for a given power assumption, unsupported combinations of TCI states may be reported.

[0117] In some embodiments, supported power assumptions may be reported for a given combination of TCI states. Alternatively, or further, unsupported power assumptions may be reported for a given combination of TCI states.

[0118] In some embodiments, the terminal device 120 may transmit a PHR containing power limiting information for STxMP. For example, the terminal device 120 may report Pcmax and MPR per panel / beam or per UE in the PHR. Since the power headroom is based on the actual transmission or reference transmission, the power headroom may better reflect the conditions on the UE side.

[0119] Figure 4 is a schematic diagram showing an exemplary PHR MAC CE according to some exemplary embodiments of the present disclosure. A single-entry PHR MAC CE is shown for illustrative purposes. It should be understood that the single-entry PHR is merely an example, and the present disclosure may also apply to multiple-entry PHRs, extended single-entry PHRs, extended multiple-entry PHRs, extended single-entry PHRs for multiple TRPs, or extended multiple-entry PHRs for multiple TRPs.

[0120] As shown in Figure 4, the R field indicates a reserved bit set to 0. The PH field indicates the power headroom level. If mpe-Reporting-FR2 is configured and the serving cell is operating on FR2, the MAC entity should set this field to 0 if the P-MPR value applied to satisfy the MPE requirement is less than P-MPR_00, and to 1 otherwise. If mpe-Reporting-FR2 is not configured or the serving cell is operating on FR1, the P field indicates whether power backoff by power management is applied. If power backoff by power management is not applied, the MAC entity should set the corresponding P CMAX,f,c If the fields have different values, the P field should be set to 1. CMAX,f,c The field is P, which is used in the calculation of the PH field mentioned above. CMAX,f,c This indicates the following. The MPE field indicates the power backoff applied to satisfy the MPE requirement when mpe-Reporting-FR2 is set, the serving cell is operating on FR2, and the P field is set to 1. If mpe-Reporting-FR2 is not set, or the serving cell is operating on FR1, or the P field is set to 0, the R bit is present instead. mpe-Reporting-FR2 indicates whether the UE reports MPE P-MPR in the PHR MAC CE.

[0121] As shown in Figure 4, field 401 may indicate a power assumption for STxMP (e.g., maximum output power). In some embodiments, if the terminal device 120 supports Pcmax per panel / beam for STxMP, then field 401 is P CMAX,f,c,t It may also be shown, where t corresponds to a panel / beam. In some embodiments, if the terminal device 120 supports an additional Pcmax for STxMP, field 401 is P CMAX,f,c,STxMP It may also indicate that. In some embodiments, if the terminal device 120 supports the same Pcmax for STxMP and other single-panel UL transmissions, then field 401 is P CMAX,f,c You may also indicate this.

[0122] As shown in Figure 4, field 402 may indicate MPR / MPE for STxMP. In some embodiments, if the terminal device 120 supports per panel / beam MPR / MPE for STxMP, field 402 indicates MPR t It may also be shown that t corresponds to a panel / beam. MPE t This indicates the power backoff applied to satisfy the MPE requirements for the panel / beam. Furthermore, information regarding the applicable panel / beam / beamset may be reported. In some embodiments, if the terminal device 120 supports additional MPR / MPE for STxMP, field 402 indicates the MPE STxMP It may also be shown. MPE STxMP This indicates the power backoff applied to meet the MPE requirements for STxMP. STxMP This may be an absolute value or a cumulative value. In some embodiments, if the terminal device 120 supports the same Pcmax for STxMP and other single-panel UL transmissions, field 402 may indicate MPE. STxMP This is for reducing the total power consumption of all panels used in STxMP. In some embodiments, additional MPE for STxMP may be for reducing the power consumption of each panel used in STxMP. In some embodiments, MPE STxMPHowever, information regarding whether the reduction is for the total power consumption of all panels used in STxMP, or for the total power consumption of each panel used in STxMP, may be reported or configured.

[0123] In some embodiments, if the conditions for triggering a PHR are met for at least one beam in the beamset, the terminal device 120 may transmit a PHR containing power limiting information. In some embodiments, if the conditions for triggering a PHR are met for one beam in the beamset, the terminal device 120 may transmit a PHR. In some embodiments, if the conditions for triggering a PHR are met for all beams in the beamset, the terminal device 120 may transmit a PHR.

[0124] For example, the conditions for triggering a PHR may be per panel / beam or for all panels / beams, and the measured periodic MPR (P-MPR) applied to satisfy the FR2 MPE requirement is greater than or equal to the mpe-Threshold for at least one activated FR2 serving cell since the last PHR transmission in the MAC entity. The mpe-Threshold is the dB threshold for reporting the MPE P-MPR when FR2 is configured.
