[0002] When Power Headroom Reporting (PHR) is triggered, the terminal calculates an actual power headroom based on the currently scheduled Physical Uplink Shared Channel (PUSCH) or a virtual power headroom based on a set of predefined parameters and reports it to the network.
[0003] To meet the target received power requirements of multiple transmission / reception points (TRPs), multiple repetitions of a single PUSCH can be transmitted using multiple sets of different power control parameters. When the UE uses multi-panel transmission, the power headroom information for each panel must be reported to the network side.

[0037] MPE stands for Maximum Permissible Exposure. The FCC and some countries have established standards for MPE, which include the maximum radiation level or maximum exposure level that can cause harm to the human body after exposure to radiation.
[0038] P-MPR stands for Power Management Maximum Power Reduction, which is the maximum permissible reduction in UE output power.

In current technology, the UE determines its maximum output power based on P-MPR and reports it to the network to ensure compliance with available battery energy absorption requirements and address unwanted radiation needs.
[0039] The following description, in conjunction with the accompanying drawings, details the power margin reporting method, terminal, and network-side equipment provided in this application through some embodiments and application scenarios.
[0040] Figure 2 This is one of the flowcharts illustrating the power margin reporting method provided in the embodiments of this application, such as... Figure 2 As shown, the method includes the following steps:
[0041] Step 200: The terminal receives configuration information, which includes at least one first resource that can be used for uplink scheduling or transmission;
[0042] Optionally, the terminal receives configuration information sent by the network-side device, the configuration information including at least one first resource, wherein the first resource can be used for uplink scheduling or transmission.
[0043] Optionally, the configuration information is configured or indicated via higher-layer signaling and / or downlink control information (DCI).
[0044] Optionally, higher-layer signaling includes Radio Resource Control (RRC) or Media Access Control (MAC) Control Element (CE).
[0045] Optionally, the first resource includes at least one of the following:
[0046] Sounding Reference Signal (SRS) resources;
[0047] SRS resource set;
[0048] Antenna panel;
[0049] Spatial relation information is associated with reference signals;
[0050] The reference signal associated with the quasi-Collocation (QCL) information in the Transceiver Configuration Indicator (TCI) status.
[0051] Optionally, the reference signal associated with the QCL information in the TCI state is the reference signal corresponding to QCL Type D in the TCI state.
[0052] Antenna panels can also be referred to as: antenna groups, antenna port groups, antenna sets, antenna port sets, beam sets, beam sub-sets, antenna arrays, antenna port arrays, antenna sub-arrays, antenna port sub-arrays, logical entities, entities, or antenna entities, etc.
[0053] Panel identifiers can include: antenna panel identifier, reference signal resource identifier, reference signal resource set identifier, TCI status identifier, quasi-collocation (QCL) information identifier, spatial relationship identifier, etc.
[0054] Optionally, the configuration information further includes target parameters associated with the first resource, the target parameters including at least one of the following:
[0055] Power change value;
[0056] PHR disables the timer;
[0057] PHR periodic trigger timer;
[0058] Maximum permissible radiation dose (MPE) threshold;
[0059] MPE reports timer disable.
[0060] In one implementation, the target parameters include at least one of the following: power change value (or power change factor) phr-Tx-PowerFactorChange; PHR prohibit timer phr-ProhibitTimer; PHR periodic trigger timer phr-PeriodicTimer; MPE threshold value mpe-Threshold; MPE reporting prohibit timer mpe-ProhibitTimer.
[0061] The target parameter is related to the first resource.
[0062] Step 201: If the terminal determines, based on the configuration information, that the power margin reporting PHR trigger condition associated with the first resource is met, then trigger PHR.
[0063] Optionally, after receiving the configuration information, the terminal determines whether the triggering conditions for power margin reporting are met. If they are met, power margin reporting is triggered.
[0064] Optionally, the power margin reporting PHR trigger condition associated with the first resource includes at least one of the following:
[0065] The PHR associated with the first resource is prevented from expiring;
[0066] The PHR periodic trigger timer associated with the first resource has expired;
[0067] The timer for preventing MPE reporting associated with the first resource from expiring is disabled.
[0068] The absolute value of the difference between the path loss measured by the current downlink path loss reference signal and the path loss at the time of the last power margin report is greater than the power change value. The first resource associated with the downlink path loss reference signal is the same as the first resource associated with the path loss reference signal used in the path loss calculation at the time of the last power margin report.
[0069] The uplink power backoff value associated with the first resource is greater than the power change value;
[0070] The maximum permissible output power reduction value P-MPR measured by the terminal is greater than or equal to the MPE threshold value;
[0071] The first resource is configured, activated, updated, or reconfigured.
[0072] Among them, timer expiration can also be called timer timeout.
[0073] In one embodiment, the triggering condition for the PHR is: the PHR disable timer associated with the first resource expires, and the absolute value of the difference between the path loss measured according to the current downlink path loss reference signal and the path loss at the time of the last power margin report is greater than the power change value.
[0074] For example, the terminal receives network-side configuration information that includes two SRS resource sets for codebook transmission. When a PUSCH transmission scheduled by a Downlink Control Information (DCI) is associated with two different SRS resources from two SRS resource sets, the terminal compares the path loss measured by the two path loss reference signals actually used by the PUSCH transmissions currently associated with different SRS resource sets with the path loss measured by the path loss reference signals associated with the same SRS resource set at the time of the last PHR report. If any set of path loss changes exceeds the power change value configured by the network side, a PHR is triggered.
[0075] In this embodiment, the terminal receives configuration information for at least one first resource for uplink transmission or scheduling. Based on the configuration information, PHR is triggered when the PHR triggering condition is met. This allows PHR to be triggered separately based on different TRP transmissions and Panel transmissions in a multi-TRP / panel scenario, effectively reducing invalid and frequent PHR triggering and improving power margin reporting efficiency.
[0076] In one implementation, the PHR is triggered when: the PHR disable timer associated with the first resource expires, and the uplink power backoff value associated with the first resource is greater than the power change value.
[0077] In one implementation, the PHR is triggered when the MAC CE updates the spatial relationships of the SRS resource in the SRS resource set.
[0078] Optionally, PHR will also be triggered when a Panel is activated.
[0079] After PHR is triggered, the terminal calculates the power margin.
[0080] Optionally, the power reporting method provided in this application embodiment further includes: the terminal calculating the power margin;
[0081] The terminal power margin calculation includes at least one of the following:
[0082] Based on the configuration information, the terminal determines the first resource situation associated with the Physical Uplink Shared Channel (PUSCH) on the first cell and / or the first resource situation associated with the PUSCH on the second cell, and calculates the power margin based on the first resource situation.
[0083] When there is an overlap between the uplink transmission opportunity scheduled on the second cell and the uplink transmission opportunity with transmission power margin, the terminal calculates the power margin based on the overlapping transmission opportunities.
[0084] If there is no uplink scheduling or resources on the second cell, and at least one first resource is configured on the second cell, the terminal calculates the virtual power margin using default or predefined power control parameters.
[0085] The first cell is the cell where the PUSCH with the transmission power margin is located;
[0086] The second cell refers to any cell other than the first cell.
[0087] The community is either the main community or the service community.
[0088] Optionally, the first cell is the cell where the PUSCH with transmission power margin is located; the second cell is a serving cell other than the first cell.
[0089] Optionally, the first cell is the serving cell where the PUSCH with transmission power margin is located; the second cell is the primary cell, and / or, other serving cells besides the first cell.
[0090] Optionally, calculating the power margin based on the first resource situation includes:
[0091] When the PUSCH of the transmission power margin is associated with at least one first resource, the terminal calculates the actual power margin based on the power control parameters corresponding to the transmission timing associated with different first resources; or,
[0092] When a PUSCH with a transmission power margin is associated with a first resource, the terminal calculates an actual power margin based on the power control parameters corresponding to a transmission timing of the PUSCH, and / or, for at least one first resource not associated with this transmission, the terminal calculates a virtual power margin using default or predefined power control parameters.
[0093] Optionally, for the PUSCH of transmission power margin, if the PUSCH of transmission power margin is associated with at least one first resource, the actual power margin is calculated based on the transmission timing associated with different first resources.
[0094] Optionally, if a first resource is associated with multiple transmission opportunities, the terminal calculates the actual power margin based on the power control parameters of the first transmission opportunities associated with different first resources. For example, the terminal calculates the actual power margin based on the power control parameters of the first transmission opportunities associated with two different SRS resources, thus obtaining two actual power margins.
[0095] Optionally, if the PUSCH of the transmission power margin is associated with a first resource, the terminal calculates an actual power margin based on the power control parameters corresponding to a transmission timing of the PUSCH of the transmission power margin.
[0096] Optionally, if the PUSCH of the transmission power margin is associated with a first resource, an actual power margin is calculated based on the power control parameters corresponding to a transmission timing of the PUSCH of the transmission power margin. Furthermore, for at least one first resource that is not associated with this transmission, a set of virtual power margins is calculated using a set of default or predefined power control parameters.
[0097] Optionally, a set of default or predefined power control parameters is associated with a first resource.
[0098] Optionally, the default or predefined power control parameters include at least one of the following:

[0101] l.
[0102] Wherein, P0-alpha represents the target received power and part of the path loss compensation factor;
[0103] PL-RS is the reference signal for path loss measurement;

[0105] Optionally, the default or predefined power control parameters are parameters from the set of power control parameters with the smallest index associated with different first resources.
[0106] Optionally, calculating the power margin based on the first resource situation includes:
[0107] When the PUSCH in the second cell is associated with at least one first resource, the terminal calculates the actual power margin based on the power control parameters corresponding to the transmission timing associated with different first resources; or,

[0109] Understandably, in carrier aggregation scenarios, for other cells besides the cell where the PUSCH with the transmission power margin is located, i.e., the second cell, the terminal also needs to report the power margin to the second cell.
[0110] In one implementation, if the PUSCH on the second cell is associated with at least one first resource, the terminal calculates the actual power margin based on the power control parameters corresponding to the transmission timings of different associated first resources. For example, the terminal calculates the actual power margin based on the power control parameters of the transmission timings of two different SRS resources, thus obtaining two actual power margins.
[0111] Optionally, if the PUSCH on the second cell is associated with at least one first resource, and a first resource is associated with at least one transmission opportunity, the terminal calculates the actual power margin based on the power control parameters corresponding to the first transmission opportunity associated with different first resources.
[0112] Optionally, if the PUSCH on the second cell is associated with a first resource, the terminal calculates an actual power margin based on the power control parameters corresponding to a transmission timing of the PUSCH on the second cell.
[0113] Optionally, if a PUSCH on the second cell is associated with a first resource, the terminal calculates an actual power margin based on the power control parameters corresponding to a transmission timing of the PUSCH on the second cell. Furthermore, for at least one first resource not associated with this transmission, the terminal calculates a virtual power margin using default or predefined power control parameters.
[0114] In some optional embodiments, when there is an overlap between the uplink transmission timing scheduled on the second cell and the uplink transmission timing with transmission power margin, the terminal calculates the power margin based on the overlapping transmission timing.
[0115] Optionally, the terminal calculates the power margin based on the overlapping transmission timings, including:
[0116] When all overlapping transmission opportunities are associated with at least one first resource, the actual power margin is calculated based on the power control parameters corresponding to the transmission opportunities associated with different first resources; or,
[0117] An actual power margin is calculated based on the power control parameters corresponding to the first transmission opportunity in the overlapping transmission opportunities, and / or a virtual power margin is calculated using default or predefined power control parameters.
[0118] In one implementation, when all overlapping transmission opportunities are associated with at least one first resource, the terminal calculates the actual power margin based on the power control parameters corresponding to the transmission opportunities associated with different first resources. For example, the terminal calculates the actual power margin based on the power control parameters of transmission opportunities associated with two different SRS resources, thus obtaining two actual power margins.
[0119] Optionally, if all overlapping transmission opportunities are associated with at least one first resource, and if a first resource is associated with at least one transmission opportunity, the actual power margin is calculated based on the power control parameters corresponding to the first transmission opportunity associated with different first resources.
[0120] In one implementation, an actual power margin is calculated based on the power control parameters corresponding to the first transmission timing in the overlapping transmission timings, while a virtual power margin is calculated using default or predefined power control parameters.
[0121] In some optional embodiments, when there is no uplink scheduling or resources on the second cell and at least one first resource is configured on the second cell, the terminal calculates the virtual power margin using default or predefined power control parameters.
[0122] Optionally, default or predefined power control parameters are associated with the first resource.
[0123] Optionally, the power control parameters include at least one of the following:
[0124] P0-alpha;
[0125] PL-RS;
[0126] l.
[0127] Wherein, P0-alpha represents the target received power and part of the path loss compensation factor;
[0128] PL-RS is the reference signal for path loss measurement;
[0129] l represents the closed-loop power control adjustment state.
[0130] Optionally, the default or predefined power control parameters are parameters from the set of power control parameters with the smallest index associated with different first resources.
[0131] Optionally, the step of calculating the virtual power margin using default or predefined power control parameters includes:
[0132] The virtual power margin is calculated using the power control parameter set with the smallest index value in at least one power control parameter set associated with the first resource;
[0133] At least one set of parameters is obtained from the power control parameters or power control parameter set in ascending order of index, and a virtual power margin is calculated based on the at least one set of parameters, wherein one set of parameters is associated with a first resource;
[0134] The virtual power margin is calculated using predefined power control parameter values.
[0135] The power control parameter set includes at least one of the following:
[0136] SRI-PUSCH-PowerControl;
[0137] P0-PUSCH-AlphaSet.
[0138] Power control parameters include: road loss reference signal and / or closed-loop power control adjustment status.
[0139] Power control can also be simply referred to as power control.
[0140] For example, virtual power margins can be calculated using the path loss reference signals from multiple sri-pusch-powercontrol systems that have the smallest index among different SRS resource sets.
[0141] For example, virtual power margins can be calculated using two path loss reference signals with index values of 0 and 1, respectively.
[0142] Optionally, calculating the virtual power margin using default or predefined power control parameters includes: calculating the virtual power margin using predefined power control parameter values. That is, the power control parameters are predefined values.
[0143] For example, the closed-loop power control adjustment states l=0 and l=1 correspond to SRS resource set 1 and SRS resource set 2, respectively.
[0144] Optionally, the uplink transmission timing includes at least one of the following:
[0145] A time unit of PUSCH;
[0146] A nominal repetition of PUSCH;
[0147] SRS transmission timing;
[0148] A time unit of the Physical Uplink Control Channel (PUCCH).
[0149] The timing unit includes: a time slot, a sub-slot, or a symbol.
[0150] Optionally, the uplink transmission timing includes at least one of the following: a slot of PUSCH; a nominal repetition of PUSCH; an SRS transmission timing; a slot of PUCCH; a sub-slot of PUCCH.
[0151] It should be noted that a nominal repetition of PUSCH refers to several consecutive OFDM symbols of PUSCH repetition type B.
[0152] In this embodiment of the application, after PHR is triggered, the terminal determines the first resource status associated with the Physical Uplink Shared Channel (PUSCH) and the PUSCH on the first serving cell, and calculates the power margin based on the first resource status. This enables the calculation of power margin information for each TRP / Panel, thereby improving the efficiency of power margin reporting.
[0153] After calculating the power margin, the terminal reports the calculated power margin to the network-side device.
[0154] Optionally, based on the above embodiments, the method further includes: the terminal reporting the power margin;
[0155] The terminal reports the power margin, including:
[0156] The terminal reports the power margin by sending a Media Access Control (MAC) control unit (CE) to the network-side device; or...
[0157] The terminal reports the power margin by sending a MAC CE and Channel State Information (CSI) report to the network-side device;
[0158] The content carried by the MAC CE satisfies the following:
[0159] For a cell, it includes at least one of the following: a first resource identifier; the actual power margin associated with the first resource; the virtual power margin associated with the first resource; and the P-MPR associated with the first resource.
[0160] The CSI report includes at least one P-MPR associated with the first resource.
[0161] Understandably, the terminal will report the calculated power margin to the network in the form of a MAC CE and / or CSI report.
[0162] In one implementation, the content carried by the MAC CE for a cell includes: at least one first resource identifier, and power margin associated with the first resource corresponding to the first resource identifier.
[0163] For example, the first resource identifier is a 1-bit identifier that identifies two SRS resource sets. Here, 0 indicates that the power margin corresponds to the one with the smaller index value in the two SRS resource sets, and 1 indicates that the power margin corresponds to the one with the larger index value in the two SRS resource sets.
[0164] In one embodiment, the first resource identifier includes a Panel identifier. The UE is configured with an SRS resource set for codebook or non-codebook transmission. When a PUSCH transmission is associated with an SRS resource, the UE calculates and reports an actual power margin based on a transmission timing, and simultaneously calculates a virtual power margin and P-MPR based on other active panels.
[0165] The power margin associated with the first resource corresponding to the first resource identifier can be either an actual power margin or a virtual power margin.
[0166] Optionally, in addition to power margin, the MAC CE may also carry at least one P-MPR associated with the first resource.
[0167] Optionally, the association between power margin and / or P-MPR and the first resource can also be implicitly indicated, sorted by the configuration or index value size of the first resource in a default sorting manner.
[0168] Each P-MPR is associated with a first resource.
[0169] In this embodiment of the application, the first resource satisfies at least one of the following: the first resource is at least one first resource associated with the currently scheduled uplink resource; the first resource is all first resources that can be used for uplink scheduling; the first resource is all active first resources; the first resource is configured by RRC or indicated by MAC CE or DCI.
[0170] In this embodiment, the terminal receives configuration information for at least one first resource used for uplink transmission or scheduling. Based on the configuration information, PHR is triggered when the PHR triggering condition is met. After PHR is triggered, the terminal determines the first resource status associated with the Physical Uplink Shared Channel (PUSCH) and the PUSCH on the first serving cell. Based on the first resource status, the power margin is calculated, which enables the calculation of power margin information for each TRP / Panel. This allows for the reporting of multiple sets of power margins in both TRP / Panel scenarios and carrier aggregation scenarios, thereby improving transmission efficiency.
