It should be noted that this application embodiment only uses a base station in an NR system as an example for description and does not limit the specific type of base station.
[0030] Before describing the embodiments of this application, the relevant technologies are briefly introduced below:
[0031] The user equipment (UE), also known as the terminal, triggers PHR reporting according to the triggering conditions specified in the protocol. The PHR reporting process is used to provide the gNB with the following information:
[0032] Type 1 power headroom: The difference between the nominal UE maximum transmit power and the estimated power transmitted on the Uplink Shared Channel (UL-SCH) of each active serving cell;
[0033] Type 2 power headroom: The difference between the nominal maximum transmit power of the UE and the estimated transmit power of the UL-SCH and Physical Uplink Control Channel (PUCCH) on the Special Cell (SpCell) of other Medium Access Control (MAC) entities. These other MAC entities can include E-UTRA NR dualconnectivity with MCG using E-UTRA and SCG using NR (EN-DC), NR-E-UTRA dual connectivity (NE-DC), or E-UTRA NR dual connectivity with E-UTRA connected to 5GC (NGEN-DC) under the 5G core network and 4G radio access network to 5G NR. UMTS terrestrial radio access MAC entity evolved from Access (E-UTRA);
[0034] Type 3 power headroom: The difference between the nominal maximum transmit power of the UE and the estimated power transmitted by the Sounding Reference Signal (SRS) on each active serving cell.
[0035] In related technologies, one PUSCH transmission corresponds to one type 1 power margin and one type 3 power margin. PHR reporting technology determines whether to report a type 1 PHR or a type 3 PHR based on a single type 1 and a single type 3. Versions 17 (R17) and 18 (R18) introduced the feature that one PUSCH transmission corresponds to two type 1 power margins. In this case, the UE cannot report PHR based on the protocol specifications in related technologies; that is, the UE cannot determine whether to report a type 1 PHR or a type 3 PHR.
[0036] Power Residue Reporting (PHR) technology is an important mechanism in 5G networks. By reporting power margin information, the UE can help network-side devices perform effective power control and resource scheduling, thereby optimizing network performance and user experience.
[0037] In view of this, embodiments of this application provide a PHR reporting method, apparatus and communication device to solve the problem of how a terminal reports PHR when a PUSCH transmission corresponds to two or more Type 1 power margins.
[0038] The PHR reporting method provided in this application will be described in detail below with reference to the accompanying drawings and through some embodiments and application scenarios.
[0039] Figure 2 A flowchart illustrating a PHR reporting method provided in an embodiment of this application is shown. Figure 2 As shown, the PHR reporting method includes the following steps:
[0040] Step 201: When the target PUSCH transmission corresponds to N power margins, the terminal reports the target PHR based on the target configuration information and at least one of the transmission methods of the N power margins;
[0041] The N power margins include L type 1 power margins and K type 3 power margins, where L is an integer greater than 1 and K is an integer greater than or equal to 1.
[0042] The target PHR is either L type 1 PHRs or K type 3 PHRs.
[0043] The power margin can be transmitted in two ways:
[0044] Firstly, power margin is based on actual transmission. This means determining the remaining available power based on the power situation during actual transmission. This transmission method allows for flexible adjustment of power allocation according to actual conditions, improving system adaptability and efficiency. It is commonly used in communication systems that require dynamic power allocation adjustments, such as mobile communication systems and satellite communication systems.
[0045] Secondly, power margin based on reference transmission. Power margin based on reference transmission refers to determining the allocation of power margin according to a pre-set reference value or standard. This transmission method allows for advance planning and adjustment of power allocation, simplifying system management and optimization processes. It is often used in communication systems with high static power control requirements or those requiring advance planning of power allocation, such as fixed communication networks and wireless local area networks.
[0046] The terminal reports the target PHR based on the target configuration information and at least one of the transmission methods of the N power margins. This can be understood as the terminal determining the target PHR to be reported based on the target configuration information and at least one of the transmission methods of the N power margins, and then reporting the target PHR.
[0047] The embodiments of this application can be applied to single downlink control information (sDCI) multiple TRP (mTRP) scenarios, or to mDCI mTRP scenarios. The embodiments of this application do not limit the application to either.
[0048] In this embodiment, when the target PUSCH transmission corresponds to N power margins, the terminal reports the target PHR based on the target configuration information and at least one of the transmission methods of the N power margins; wherein, the N power margins include L type 1 power margins and K type 3 power margins, where L is an integer greater than 1 and K is an integer greater than or equal to 1; the target PHR is either the L type 1 PHRs or the K type 3 PHRs. This enables the terminal to report PHRs.
[0049] In some embodiments, step 201 includes:
[0050] The terminal reports the target PHR to the network-side device.
[0051] For network-side devices, the target PHR reported by the terminal is received by the network-side device.
[0052] In some embodiments, prior to step 201, the method further includes:
[0053] The terminal obtains the target configuration information from the network-side device.
[0054] For network-side devices, the target configuration information is sent to the terminal.
[0055] In some embodiments, the terminal reports a target PHR based on at least one of the target configuration information and the transmission methods of the N power margins, including at least one of the following:
[0056] When at least one of the L type 1 power margins is based on actual transmission, the terminal reports L type 1 PHRs;
[0057] When all L types 1 power margins are based on reference transmission, and at least one of the K types 3 power margins is based on actual transmission, the terminal reports the PHR of the K types 3.
[0058] When the target configuration information is used to configure a Time Division Multiplexing (TDM) repetition scheme (such as the R17 TDM repetition scheme), and the power margins of the L types 1 and the K types 3 are both based on reference transmissions, the terminal reports the PHRs of the L types 1. Specifically, the TDM repetition scheme can be understood as different transmission times of the PUSCH corresponding to different beams (i.e., Transmission Configuration Indicator (TCI) states). This transmission mode is entered when the UE is configured with two SRS resource sets for codebook or non-codebook transmission and is not configured for simultaneous transmission; or, when the UE is configured with two SRS resource sets for codebook or non-codebook transmission, this transmission mode is entered.
[0059] When the target configuration information is used to configure the TDM repetition scheme, and at least one of the L type 1 power margins is based on actual transmission, the terminal reports L type 1 PHRs.
[0060] When the target configuration information is used to configure the TDM repetition scheme, and the power margins of the L types 1 are all based on reference transmission, and at least one of the power margins of the K types 3 is based on actual transmission, the terminal reports the PHR of the K types 3.
[0061] When the target configuration information is used to configure simultaneous multiple panel transmission (sTXMP) (such as R18 sTXMP), the terminal reports L type 1 PHRs. The target configuration information being used to configure sTXMP can be understood as entering a multi-panel simultaneous transmission mode. For example, in the sDCI mTRP scenario, with R18 sTXMP configured, the terminal reports two type 1 PHRs; similarly, in the mDCI mTRP scenario, with R18 sTXMP configured, the terminal reports two type 1 PHRs. In the sDCI mTRP scenario, with R18 sTXMP configured, it can be understood that two resource sets for codebook transmission are configured and the multipanelScheme parameter is configured; in the mDCI mTRP scenario, with R18 sTXMP configured, it can be understood that enableSTx2PofmDCI is configured.
[0062] If the target configuration information satisfies the first condition, the terminal reports L PHRs of type 1; the first condition will be explained later.
[0063] If the target configuration information satisfies the first condition and the transmission method of the N power margins satisfies the second condition, the terminal reports L type 1 PHRs; the first and second conditions will be explained later.
[0064] If the target configuration information meets the third condition, the terminal reports K PHRs of type 3; the third condition will be explained later.
[0065] If the target configuration information satisfies the third condition and the transmission method of the N power margins satisfies the fourth condition, the terminal reports K PHRs of type 3; the third and fourth conditions will be explained later.
[0066] This implementation provides multiple PHR reporting strategies to assist the UE in flexibly reporting more power information, thereby helping the network-side equipment to better adjust multiple power settings. Specifically, in TDM transmission mode, it can help the UE determine the type of PHR to report based on L type 1 PHRs and K type 3 PHRs, enabling the UE to report as much information as possible, thus assisting the network-side equipment in determining uplink power control. In multi-panel simultaneous transmission mode, the UE's maximum transmission power is determined based on each panel. Therefore, regardless of whether the type 1 power margin is based on actual transmission or reference transmission, selecting to report two type 1 PHRs to the network-side equipment allows the maximum transmit power of both panels to be reported to the network-side equipment, which helps the network-side equipment perform power control per panel, thereby improving the performance of multi-panel simultaneous transmission.
[0067] In some embodiments, the first condition includes at least one of the following:

[0077] For example, configuring the fourth mode could be: on active DL BWPs of serving cells, for the first CORESET, the UE does not provide a coresetPoolIndex, or provides a coresetPoolIndex with a value of 0; for the second CORESET, the UE provides a coresetPoolIndex with a value of 1, and enables STx2PofmDCI.

[0138] Example 1: If the UE is configured with two SRS resource sets for codebook or non-codebook and two power margin reporting modes, and the two type 1 power margins and one type 3 power margin are based on reference transmission, then the UE reports the type 1 power margin report.

[0141] Example 4: If the UE is configured with two SRS resource sets for codebook or non-codebook and two power margin reporting modes, and the two type 1 power margins are based on reference transmissions, while the one type 3 power margin is based on actual transmissions, then the UE reports a type 3 power margin report.
[0142] Example 5: If the UE is configured with two SRS resource sets for codebook or non-codebook, and has configured two power margin reporting modes, and has configured a multi-panel simultaneous transmission mode, then the UE reports a power margin report of type 1.
