Description

[Technical Field]

[0001] The present disclosure relates to the field of communications technology, and in particular to a method, apparatus, user equipment, base station, and storage medium for reporting a power headroom report. [Background technology]

[0002] In a communication system, a UE (User Equipment) usually needs to report a PHR (Power Headroom Report) to meet the scheduling requirements of a network. In the related art, the UE reports the PHR based on power control parameters and PHR reporting trigger conditions.

[0003] However, if the UE supports multiple TRP (Transmission Reception Point) transmissions, when the UE reports a PHR to the network, the network can reliably know the correlation between the reported PHR and different power control parameters, or the correlation between the TRP and the PHR, which will affect the uplink scheduling for the UE and prevent the network resources from being allocated effectively. Therefore, a PHR reporting method adapted to multi-TRP scenarios is needed. Summary of the Invention [Problem to be solved by the invention]

[0004] The present disclosure provides a power headroom reporting method, device, user equipment, base station, core network device, and storage medium, thereby providing a PHR reporting method that is adapted to Multi-TRP scenarios. [Means for solving the problem]

[0041] In one embodiment of the present disclosure, the second information corresponding to the carrier may include any one of the above. In another embodiment of the present disclosure, the second information corresponding to the carrier may include any combination of the above.

[0042] Step 104: triggering PHR reporting of at least two TRPs corresponding to each carrier according to the power control parameters and reporting trigger conditions;

[0043] Here, in one embodiment of the present disclosure, the UE may report the PHR of each TRP corresponding to each carrier to the base station.

[0044] A specific method for the UE to report the PHR of each TRP in each carrier to the base station will be described in the following embodiment.

[0045] In one embodiment of the present disclosure, the UE can report to the base station not only the PHR of each TRP of each carrier, but also the PHR of multiple TRPs corresponding to each carrier, where the number of reported TRPs is smaller than the number of TRPs in the corresponding carrier, and the TRP of the reported PHR may specifically be a TRP whose related information has changed, where the related information may include at least one of identification information corresponding to the TRP, a downlink path loss reference carrier corresponding to the TRP, and a transmission carrier of an uplink physical channel corresponding to the TRP.

[0046] For example, assume that a certain carrier includes TRP-1, TRP-2, and TRP-3. If the downlink path loss reference carriers for TRP-1 and TRP-2 change, the PHRs for TRP-1 and TRP-2 can be reported to the base station.

[0047] As described above, in a power headroom reporting method provided by an embodiment of the present disclosure, a UE receives power control parameters for at least one TRP corresponding to at least one carrier and a PHR report trigger condition corresponding to the at least one TRP transmitted from a base station. The base station then triggers a PHR report for at least two TRPs corresponding to each carrier based on the power control parameters and the report trigger condition. As can be seen from this, an embodiment of the present disclosure provides a PHR reporting method for a multi-TRP scenario. Furthermore, in the method provided by the embodiment of the present disclosure, the power control parameters include not only power control parameters corresponding to a carrier but also power control parameters corresponding to TRPs on the carrier, and the PHR report trigger condition includes not only trigger conditions based on the power control parameters corresponding to a carrier but also trigger conditions based on the power control parameters corresponding to TRPs on the carrier, thereby enhancing the configuration of the power control parameters and the PHR report trigger condition.

[0048] In the embodiment of the present disclosure, when reporting PHR, various options are added to the report content, enriching the report content without increasing the amount of report data. At the same time, in the embodiment of the present disclosure, when reporting PHR, the TRP identifier is also reported, so that the base station can reliably know the TRP corresponding to the reported PHR, thereby supporting dynamic scheduling under different conditions on different channels, realizing accurate power control, and ensuring effective allocation of network resources.

[0049] FIG. 2 is a schematic flowchart of a power headroom report method provided by an embodiment of the present disclosure, which is applied to a UE. As shown in FIG. 2, the power headroom report method may include the following steps 201 to 205.

[0050] Step 201: Receive setting information sent from the base station.

[0051] Step 202: receiving power control parameters supporting one or more TRPs corresponding to at least one carrier transmitted from a base station;

[0052] Step 203: receiving a PHR reporting trigger condition corresponding to one or more TRPs sent from a base station;

[0053] Step 204: Determine whether the UE meets the reporting trigger condition based on the power control parameters and the reporting trigger condition; if yes, execute step 202;

[0054] Here, in one embodiment of the present disclosure, if the UE meets the reporting trigger condition, it means that it needs to send a current reporting PHR to the base station, so it may continue to execute step 202.

[0055] Here, for the explanation related to steps 201 to 204, please refer to the above embodiment, and detailed explanation will be omitted in the embodiment of the present disclosure.

[0056] Step 202: Send PHRs of each TRP in each carrier to the base station.

[0057] Here, in one embodiment of the present disclosure, transmitting a PHR of each TRP in each carrier to a base station may include a step of sorting each TRP in each carrier, sequentially sorting the PHR of each TRP according to the sorting order of each TRP, and then sending the sequentially sorted PHR of each TRP to the base station.

[0058] In one embodiment of the present disclosure, rearranging each TRP in the above step includes: Sorting each TRP according to a predefined sorting rule; Sorting each TRP according to the sorting rules specified by the protocol; Sorting each TRP according to the sorting rules set / instructed by the network; The UE autonomously reorders each TRP.

[0059] Here, in one embodiment of the present disclosure, the sorting rule may be, for example, an order defined by each TRP transmission when multiple TRPs perform PUSCH transmission. In another embodiment of the present disclosure, the sorting rule may be, for example, sorting the TRPs in ascending order based on the number of each TRP for each carrier. In another embodiment of the present disclosure, the sorting rule may be, for example, sorting the TRPs in ascending order based on the number of each TRP for each carrier.

[0060] Furthermore, in one embodiment of the present disclosure, when the UE reports the PHR of each TRP in each carrier to the base station, the reporting content of the PHR may include a related second power parameter, where the related second power parameter is: reporting the power back-off value for each TRP in turn; UE power backoff value Report the , including at least one of.

[0061] Here, in one embodiment of the present disclosure, the associated second power parameter may include any one of the above, and in another embodiment of the present disclosure, the associated second power parameter may include any combination of the above.

[0062] Taking PUSCH as an example (similar to PUCCH / SRS / PRACH), the above "transmitting actual PUSCH" and "transmitting reference PUSCH" will be explained.

[0063] In one embodiment of the present disclosure, the "power headroom after transmitting an actual PUSCH" refers to the power headroom of the PUSCH after an actual transmission is performed on the PUSCH.

[0064] In one embodiment of the present disclosure, the "power headroom after transmitting a reference PUSCH" means that when a PUSCH is not actually transmitted but the power headroom of the PUSCH needs to be reported, the UE may determine a reference PUSCH based on an instruction from the network, use the transmission format and transmission parameters corresponding to the reference PUSCH to calculate the power headroom of the PUSCH of the PHR or other channels that need to be reported, and report the calculated power headroom as the power headroom of the PUSCH of the PHR that needs to be reported.

[0065] In addition, in one embodiment of the present disclosure, based on the fact that the PHR report content includes the above-mentioned related second power parameter, the UE may selectively add an identifier of each TRP to the PHR report content.

[0066] That is, in one embodiment of the present disclosure, when the UE reports the PHR, the report content may include the associated second power parameter. In another embodiment of the present disclosure, when the UE reports the PHR, the report content may include the associated second power parameter plus the identifier of each TRP to be sequentially sorted.

[0067] As described above, in a power headroom reporting method provided by an embodiment of the present disclosure, a UE receives power control parameters for at least one TRP corresponding to at least one carrier and a PHR report trigger condition corresponding to the at least one TRP transmitted from a base station. The base station then triggers a PHR report for at least two TRPs corresponding to each carrier based on the power control parameters and the report trigger condition. As can be seen from this, an embodiment of the present disclosure provides a PHR reporting method for a multi-TRP scenario. Furthermore, in the method provided by the embodiment of the present disclosure, the power control parameters include not only power control parameters corresponding to a carrier but also power control parameters corresponding to TRPs on the carrier, and the PHR report trigger condition includes not only trigger conditions based on the power control parameters corresponding to a carrier but also trigger conditions based on the power control parameters corresponding to TRPs on the carrier, thereby enhancing the configuration of the power control parameters and the PHR report trigger condition.

[0068] In the embodiment of the present disclosure, when reporting PHR, various options are added to the report content, enriching the report content without increasing the amount of report data. At the same time, in the embodiment of the present disclosure, when reporting PHR, the TRP identifier is also reported, so that the base station can reliably know the TRP corresponding to the reported PHR, thereby supporting dynamic scheduling under different conditions on different channels, realizing accurate power control, and ensuring effective allocation of network resources.

[0069] FIG. 3a is a schematic flowchart of a power headroom reporting method provided by an embodiment of the present disclosure, which is applied to a UE. As shown in FIG. 3a, the power headroom reporting method may include the following steps 301 to 305:

[0070] Step 301: Receive setting information sent from the base station.

[0071] Step 302: receiving power control parameters supporting one or more TRPs corresponding to at least one carrier transmitted from a base station;

[0072] Step 303: receiving a PHR reporting trigger condition corresponding to one or more TRPs sent from a base station;

[0073] Step 304: Determine whether the UE meets the reporting trigger condition based on the power control parameters and the reporting trigger condition; if yes, execute step 302;

[0074] Here, in one embodiment of the present disclosure, if the UE meets the reporting trigger condition, it means that it needs to send a current reporting PHR to the base station, so it may continue to execute step 302.

[0075] Here, for the explanation related to steps 301 to 304, please refer to the above embodiment, and detailed explanation will be omitted in the embodiment of the present disclosure.

[0076] Step 305: Send a PHR of each TRP in each carrier to the base station, where the report content of the PHR includes the associated second power parameter.

[0077] Here, in one embodiment of the present disclosure, the associated second power parameter is: reporting the power back-off value for each TRP in turn; UE power backoff value Report the , including at least one of.

[0078] Here, in one embodiment of the present disclosure, the associated second power parameter may include any one of the above, and in another embodiment of the present disclosure, the associated second power parameter may include any combination of the above.

[0079] In one embodiment of the present disclosure, the UE can report the PHR of each TRP via MAC-CE (Media Access Control Address Control Element) signaling.

[0080] The following describes an example of the MAC-CE report format of the PHR when the report content of the PHR of each TRP includes the associated second power parameter.

[0081] 3b is a schematic diagram of a MAC-CE reporting format for each PHR in a single TRP transmission provided by an embodiment of the present disclosure. As shown in FIG. 3b, the MAC-CE reporting format for each PHR in a single TRP includes the domains "P", "PH", "MPE", and "P CMAC,f,c " includes.

[0082] 3c is a schematic diagram of a MAC-CE reporting format of each PHR when it is transmitted in multiple TRPs and the number of cells is 8 or less, provided by an embodiment of the present disclosure. As shown in FIG. 3c, the MAC-CE reporting format of the PHR in multiple TRPs is divided into domains “P”, “PH”, “MPE”, “P CMAC,f,ci ", "V", "C i " includes.

[0083] 3d is a schematic diagram of a MAC-CE reporting format of each PHR when it is transmitted in multiple TRPs and the number of cells is greater than 8, provided by an embodiment of the present disclosure. As shown in FIG. 3d, the MAC-CE reporting format of the PHR in multiple TRPs is divided into domains “P”, “PH”, “MPE”, “P CMAC,f,ci ", "V", "C i " includes.

[0084] Here, the meaning of each of the above domains is as follows:

[0085] C iIf one SCell configures SCellIndex via an RRC message, the domain indicates whether the PH domain of the SCell with SCellIndex i configured has been reported. i The domain being set to '1' indicates that the PH domain of the SCell with SCellIndex i is reported. i The domain being set to '0' indicates that the domain of the SCell with SCellIndex i is not reported. R: Reserved bit, set to "0". V: This domain indicates whether the reported PH value is based on actual transmission or reference format. For Type 1 PH, V=0 indicates true transmission on PUSCH, and V=1 indicates using a reference format with PUSCH. For Type 2 PH, V=0 indicates actual transmission on PUCCH, and V=1 indicates using a reference format with PUCCH. For Type 3 PH, V=0 indicates actual transmission on SRS, and V=1 indicates using a reference format with SRS. Also, for Type 1, Type 2 and Type 3 PH, V=0 indicates that the reporting format includes the P corresponding to a cell. CMAX,c V=1 indicates that the report format includes a P corresponding to a cell. CMAX,c Indicates that the domain is not included. PH: The domain indicates the level of power headroom. P: The domain indicates whether the current MAC entity uses a power backoff mechanism. If there is no power backoff, P corresponds to a cell. CMAX,c If the domain has different possible values, set the MAC entity to P=1. MPE: The domain indicates the maximum permissible exposure.

[0086] The pH type is Type 1 PH:PH type1,c(i) = P CMAX,c -PPUSCH,c(i) Type 2 PH:PH type2,c(i) = P CMAX,c -P PUSCH,c(i) -P PUCCH,c(i) Type 3 PH:PH type3,c(i) = P CMAX,c -P SRS,c(i) Including, Here, "i" is a certain subframe "i".

[0087] P PUSCH,c(i) is the transmit power of the uplink data channel (PUSCH) calculated by the UE. If the UE transmits a real signal, the value is determined based on the actually transmitted channel power. If the UE does not transmit a real signal, the value is determined by the reference (or virtual) channel power. P PUCCH,c(i) is the transmit power of the uplink control channel (PUCCH) calculated by the UE. If the UE transmits a real signal, the value is determined based on the actually transmitted channel power. If the UE does not transmit a real signal, the value is determined by the reference (or virtual) channel power. P SRS,c(i) is the transmit power of the uplink measurement reference channel (SRS) calculated by the UE. If the UE transmits a real signal, the value is determined based on the actually transmitted channel power. If the UE does not transmit a real signal, the value is determined by the reference (or virtual) channel power. P CMAX,c For a domain, if it exists, it is necessary to calculate the corresponding domain value P CMAX,cThe value of , i.e., the maximum power that the UE can transmit in the cell calculated by the UE. As described above, in the power headroom reporting method provided by the embodiment of the present disclosure, the UE receives a power control parameter of at least one TRP corresponding to at least one carrier and a PHR report trigger condition corresponding to the at least one TRP transmitted from the base station. Then, the base station triggers a PHR report for at least two TRPs corresponding to each carrier based on the power control parameter and the report trigger condition. As can be seen from this, the embodiment of the present disclosure provides a PHR reporting method in a multi-TRP scenario. Furthermore, in the method provided by the embodiment of the present disclosure, the power control parameters include not only power control parameters corresponding to a carrier but also power control parameters corresponding to TRPs on the carrier, and the PHR report trigger condition includes not only trigger conditions based on the power control parameters corresponding to a carrier but also trigger conditions based on the power control parameters corresponding to TRPs on the carrier, thereby enhancing the configuration of the power control parameters and the PHR report trigger condition.

[0088] In the embodiment of the present disclosure, when reporting PHR, various options are added to the report content, enriching the report content without increasing the amount of report data. At the same time, in the embodiment of the present disclosure, when reporting PHR, the TRP identifier is also reported, so that the base station can reliably know the TRP corresponding to the reported PHR, thereby supporting dynamic scheduling under different conditions on different channels, realizing accurate power control, and ensuring effective allocation of network resources.

[0089] FIG. 4a is a schematic flowchart of a power headroom reporting method provided by an embodiment of the present disclosure, which is applied to a UE. As shown in FIG. 4a, the power headroom reporting method includes the following steps 401 to 405.

[0090] Step 401: Receive setting information sent from the base station.

[0091] Step 402: receiving power control parameters supporting one or more TRPs corresponding to at least one carrier transmitted from a base station;

[0092] Step 403: receiving a PHR reporting trigger condition corresponding to one or more TRPs sent from a base station;

[0093] Step 404: Determine whether the UE meets the reporting trigger condition based on the power control parameters and the reporting trigger condition; if yes, execute step 402;

[0094] Here, in one embodiment of the present disclosure, if the UE meets the reporting trigger condition, it means that it needs to send a current reporting PHR to the base station, so it may continue to execute step 402.

[0095] Here, for the explanation related to steps 401 to 404, please refer to the above embodiment, and detailed explanation will be omitted in the embodiment of the present disclosure.

[0096] Step 402: Send a PHR of each TRP in each carrier to the base station, where the report content of the PHR includes the associated second power parameter and the identifier of each TRP.

[0097] Here, in one embodiment of the present disclosure, the associated second power parameter is: reporting the power back-off value for each TRP in turn; UE power backoff value Report the , may include at least one of.

[0098] Here, in one embodiment of the present disclosure, the associated second power parameter may include any one of the above, and in another embodiment of the present disclosure, the associated second power parameter may include any combination of the above.

[0099] In one embodiment of the present disclosure, the UE may report the PHR of each TRP via MAC-CE signaling.

[0100] Below, an example is given to explain the MAC-CE reporting format of the PHR when the report content of the PHR of each TRP includes the associated second power parameter and the identifier of each TRP.

[0101] 4b is a schematic diagram of a MAC-CE reporting format for each PHR in a single TRP transmission provided by an embodiment of the present disclosure. As shown in FIG. 4b, the MAC-CE reporting format for each PHR in a single TRP includes the domains "P", "PH", "MPE", and "P CMAC,f,c "," and "TRP".

[0102] 4c is a schematic diagram of a MAC-CE reporting format of each PHR when it is transmitted in multiple TRPs and the number of cells is 8 or less, provided by an embodiment of the present disclosure. As shown in FIG. 4c, the MAC-CE reporting format of the PHR in multiple TRPs is divided into domains “P”, “PH”, “MPE”, “P CMAC,f,ci ", "V", "C i "," and "TRP".

[0103] 4d is a schematic diagram of a MAC-CE reporting format of each PHR when it is transmitted in multiple TRPs and the number of cells is greater than 8, provided by an embodiment of the present disclosure. As shown in FIG. 4d, the MAC-CE reporting format of the PHR in multiple TRPs is divided into domains “P”, “PH”, “MPE”, “P CMAC,f,ci ", "V", "C i "," and "TRP".

[0104] Here, for an explanation of the meaning of each domain, please refer to the above examples, and detailed explanations will be omitted in the examples of the present disclosure.

[0105] In one embodiment of the present disclosure, in addition to the TRP indication methods shown in Figures 4b to 4d, a TRP identifier may be indicated using a unified TRP bitmap indication method on each carrier, and then values ​​such as P, V, Pcmax, and PH corresponding to different TRPs are indicated according to a predefined order.

[0106] As described above, in a power headroom reporting method provided by an embodiment of the present disclosure, a UE receives power control parameters for at least one TRP corresponding to at least one carrier and a PHR report trigger condition corresponding to the at least one TRP transmitted from a base station. The base station then triggers a PHR report for at least two TRPs corresponding to each carrier based on the power control parameters and the report trigger condition. As can be seen from this, an embodiment of the present disclosure provides a PHR reporting method for a multi-TRP scenario. Furthermore, in the method provided by the embodiment of the present disclosure, the power control parameters include not only power control parameters corresponding to a carrier but also power control parameters corresponding to TRPs on the carrier, and the PHR report trigger condition includes not only trigger conditions based on the power control parameters corresponding to a carrier but also trigger conditions based on the power control parameters corresponding to TRPs on the carrier, thereby enhancing the configuration of the power control parameters and the PHR report trigger condition.

[0107] In the embodiment of the present disclosure, when reporting PHR, various options are added to the report content, enriching the report content without increasing the amount of report data. At the same time, in the embodiment of the present disclosure, when reporting PHR, the TRP identifier is also reported, so that the base station can reliably know the TRP corresponding to the reported PHR, thereby supporting dynamic scheduling under different conditions on different channels, realizing accurate power control, and ensuring effective allocation of network resources.

[0108] In addition, for a situation where the UE supports reporting of PHRs of single or multiple TRPs on one carrier, there is also a special case when the UE reports the PHRs of the TRPs, namely, the UE triggers reporting of a single TRP corresponding to each carrier.

[0109] Specifically, in one embodiment of the present disclosure, the UE can specifically determine, based on the dynamic TRP scheduling indication information sent from the base station, whether to report a PHR of one TRP corresponding to each carrier to the base station, or to report a PHR of each TRP corresponding to each carrier to the base station.

[0110] Specifically, in one embodiment of the present disclosure, the dynamic TRP scheduling indication information indicates whether the UE's current transmission is in a single-TRP transmission state or a multi-TRP transmission state. Here, if the dynamic TRP scheduling indication information indicates that the UE's current transmission is in a single-TRP transmission state, the UE may report a PHR of one TRP corresponding to each carrier to the base station. If the dynamic TRP scheduling indication information indicates that the UE's current transmission is in a multi-TRP transmission state, the UE may report a PHR of each TRP corresponding to each carrier to the base station.

[0111] The following embodiments in Figures 5 to 7 illustrate a special case, namely, "UE triggers reporting of a single TRP corresponding to each carrier."

[0112] FIG. 5 is a schematic flowchart of a power headroom report method provided by an embodiment of the present disclosure, which is applied to a UE. As shown in FIG. 5, the power headroom report method may include the following steps:

[0113] Step 501: Receive setting information sent from the base station.

[0114] Step 505: receiving power control parameters supporting one or more TRPs corresponding to at least one carrier transmitted from a base station;

[0115] Step 506: receiving a PHR reporting trigger condition corresponding to one or more TRPs sent from the base station;

[0116] Here, for the explanation related to steps 501 to 507, please refer to the above embodiment, and detailed explanation will be omitted in the embodiment of the present disclosure.

[0117] Step 507: Determine whether the UE meets the reporting trigger condition based on the power control parameters and the reporting trigger condition; if yes, execute step 505;

[0118] Here, in one embodiment of the present disclosure, if the UE meets the reporting trigger condition, it means that it needs to send a current reporting PHR to the base station, so it may continue to execute step 505.

[0119] Step 505: Select one TRP from the plurality of TRPs corresponding to each carrier.

[0120] Here, in one embodiment of the present disclosure, a method for a UE to select one TRP from a plurality of TRPs corresponding to a carrier includes: Method 1: Selecting one TRP from the carrier according to predefined selection rules; Method 2: Selecting one TRP from the carrier according to the selection rules set / instructed by the network; Method 3: Self-selecting one TRP from a carrier.

[0121] Here, in one embodiment of the present disclosure, the selection rules in Method 1 and Method 2 are: Rule 1: Select a TRP corresponding to a predefined transmission timing in the carrier as one TPR; or Rule 2: Any one TRP in the carrier may be set as the one TRP by default.

[0122] In one embodiment of the present disclosure, the predefined transmission timing in Rule 1 is, for example, the first transmission timing in a carrier. In one embodiment of the present disclosure, the rule in Rule 2 that any one TRP on a carrier is set as a single TRP by default may be, for example, that the TRP with the smallest or largest number corresponding to the carrier is set as the single TRP by default.

[0123] Furthermore, in one embodiment of the present disclosure, in Method 3, the UE autonomously selects one TRP from a carrier, the TRP with the worst actual power control parameters in the carrier is determined as the one TRP to report the PHR.

[0124] Step 506: Report the PHR of one TRP corresponding to each carrier to the base station.

[0125] Here, in one embodiment of the present disclosure, the report content of the PHR of one TRP reported by the UE to the base station may include a related first power parameter, where the related first power parameter is: In response to power backoff being configured on the carrier, reporting a maximum power that one TRP can transmit on the carrier after the power backoff; In response to the PUSCH being configured on the carrier and the UE transmitting the actual PUSCH, one TRP reports a power headroom after transmitting the actual PUSCH; In response to the PUSCH being configured on the carrier and the UE transmitting the actual PUSCH, reporting a power headroom after one TRP transmits a reference PUSCH; In response to a PUSCH being configured on the carrier and the UE not transmitting an actual PUSCH, reporting a power headroom after one TRP transmits a reference PUSCH; In response to the PUCCH being configured on the carrier and the UE transmitting the actual PUCCH, reporting a power headroom after one TRP transmits the actual PUCCH; In response to a PUCCH being configured on the carrier and the UE transmitting an actual PUCCH, reporting a power headroom after one TRP transmits a reference PUCCH; In response to a PUCCH being configured on the carrier and the UE not transmitting an actual PUCCH transmission, reporting a power headroom after one TRP transmits a reference PUCCH; In response to the SRS being configured on the carrier and the UE transmitting the actual SRS, one TRP reports a power headroom after transmitting the actual SRS; In response to the SRS being configured on the carrier and the UE transmitting the actual SRS, reporting a power headroom after one TRP transmits a reference SRS; In response to the SRS being configured on the carrier and the UE not transmitting the actual SRS, reporting a power headroom after one TRP transmits a reference SRS; In response to the PRACH being configured on the carrier and the UE transmitting the true PRACH, reporting a power headroom after one TRP transmits the true PRACH; In response to the PRACH being configured on the carrier and the UE transmitting the true PRACH, reporting a power headroom after one TRP transmits a reference PRACH; In response to a PRACH being configured on the carrier and the UE not transmitting an actual PRACH, reporting a power headroom after one TRP transmits a reference PRACH; and reporting a power back-off value for the UE.

[0126] In one embodiment of the present disclosure, the report content may include any one of the above. In another embodiment of the present disclosure, the report content may include any combination of the above.

[0127] The above "transmitting actual PUSCH" and "transmitting reference PUSCH" will be explained using PUSCH as an example (similar to PUCCH / SRS / PRACH).

[0128] In one embodiment of the present disclosure, the "power headroom after transmitting an actual PUSCH" refers to the power headroom of the PUSCH after an actual transmission is performed on the PUSCH.

[0129] In one embodiment of the present disclosure, the "power headroom after transmitting a reference PUSCH" means that when a PUSCH is not actually transmitted but the power headroom of the PUSCH needs to be reported, the UE may determine a reference PUSCH based on an instruction from the network, use the transmission format and transmission parameters corresponding to the reference PUSCH to calculate the power headroom of the PUSCH of the PHR or other channels that need to be reported, and report the calculated power headroom as the power headroom of the PUSCH of the PHR that needs to be reported.

[0130] In addition, in one embodiment of the present disclosure, based on the PHR report content including the above-mentioned related first power parameter, the UE may selectively add a TRP identifier to the PHR report content.

[0131] That is, in one embodiment of the present disclosure, when the UE reports the PHR, the report content may include the associated first power parameter. In another embodiment of the present disclosure, when the UE reports the PHR, the report content may include the associated first power parameter+TRP identifier.

[0132] As described above, in a power headroom reporting method provided by an embodiment of the present disclosure, a UE receives power control parameters for at least one TRP corresponding to at least one carrier and a PHR report trigger condition corresponding to the at least one TRP transmitted from a base station. The base station then triggers a PHR report for at least two TRPs corresponding to each carrier based on the power control parameters and the report trigger condition. As can be seen from this, an embodiment of the present disclosure provides a PHR reporting method for a multi-TRP scenario. Furthermore, in the method provided by the embodiment of the present disclosure, the power control parameters include not only power control parameters corresponding to a carrier but also power control parameters corresponding to TRPs on the carrier, and the PHR report trigger condition includes not only trigger conditions based on the power control parameters corresponding to a carrier but also trigger conditions based on the power control parameters corresponding to TRPs on the carrier, thereby enhancing the configuration of the power control parameters and the PHR report trigger condition.

[0133] In the embodiment of the present disclosure, when reporting PHR, various options are added to the report content, enriching the report content without increasing the amount of report data. At the same time, in the embodiment of the present disclosure, when reporting PHR, the TRP identifier is also reported, so that the base station can reliably know the TRP corresponding to the reported PHR, thereby supporting dynamic scheduling under different conditions on different channels, realizing accurate power control, and ensuring effective allocation of network resources.

[0134] FIG. 6a is a schematic flowchart of a power headroom report method provided by an embodiment of the present disclosure, which is applied to a UE. As shown in FIG. 6a, the power headroom report method may include the following steps:

[0166] 7c is a schematic diagram of a MAC-CE reporting format of a PHR when it is transmitted in multiple TRPs and the number of cells is 8 or less, provided by an embodiment of the present disclosure. As shown in FIG. 7c, the MAC-CE reporting format of a PHR in a single TRP is divided into domains "P", "PH", "MPE", and "P CMAC,f,ci ", "V", "C i "," and "TRP".

[0167] 7d is a schematic diagram of a MAC-CE reporting format of a PHR when it is transmitted in multiple TRPs and the number of cells is greater than 8, provided by an embodiment of the present disclosure. As shown in FIG. 7d, the MAC-CE reporting format of a PHR in a single TRP is divided into domains “P”, “PH”, “MPE”, and “P CMAC,f,ci ", "V", "C i "," and "TRP".

[0168] Here, the meaning of the domain "TRP" is the identifier of one TRP to which PHR on each carrier is reported.

At the same time, in the embodiment of the present disclosure, when reporting PHR, the TRP identifier is also reported, so that the base station can reliably know the TRP corresponding to the reported PHR, thereby supporting dynamic scheduling under different conditions on different channels, realizing accurate power control, and ensuring effective allocation of network resources.

[0190] Here, in one embodiment of the present disclosure, the UE may report the PHR of each TRP corresponding to each carrier to the base station.

[0191] A specific method for the UE to report the PHR of each TRP in each carrier to the base station will be described in the following embodiment.

[0192] In one embodiment of the present disclosure, in addition to reporting the PHR of each TRP corresponding to each carrier to the base station, the UE may also report the PHR of multiple TRPs corresponding to each carrier to the base station, where the number of reported TRPs is smaller than the number of TRPs in the corresponding carrier, and the TRP of the reported PHR may specifically be a TRP whose related information has been changed, where the related information may include at least one of identification information corresponding to the TRP, a downlink path loss reference carrier corresponding to the TRP, and a transmission carrier of an uplink physical channel corresponding to the TRP.

[0193] For example, assume that a certain carrier includes TRP-1, TRP-2, and TRP-3. If the downlink path loss reference carriers for TRP-1 and TRP-2 change, the PHRs for TRP-1 and TRP-2 can be reported to the base station.

[0194] As described above, in a power headroom reporting method provided by an embodiment of the present disclosure, a UE receives power control parameters for at least one TRP corresponding to at least one carrier and a PHR report trigger condition corresponding to the at least one TRP transmitted from a base station. The base station then triggers a PHR report for at least two TRPs corresponding to each carrier based on the power control parameters and the report trigger condition. As can be seen from this, an embodiment of the present disclosure provides a PHR reporting method for a multi-TRP scenario. Furthermore, in the method provided by the embodiment of the present disclosure, the power control parameters include not only power control parameters corresponding to a carrier but also power control parameters corresponding to TRPs on the carrier, and the PHR report trigger condition includes not only trigger conditions based on the power control parameters corresponding to a carrier but also trigger conditions based on the power control parameters corresponding to TRPs on the carrier, thereby enhancing the configuration of the power control parameters and the PHR report trigger condition.

[0204] In one embodiment of the present disclosure, the "power headroom after transmitting an actual PUSCH" refers to the power headroom of the PUSCH after an actual transmission is performed on the PUSCH.

[0205] In one embodiment of the present disclosure, the "power headroom after transmitting a reference PUSCH" means that when a PUSCH is not actually transmitted but the power headroom of the PUSCH needs to be reported, the UE may determine a reference PUSCH based on an instruction from the network, use the transmission format and transmission parameters corresponding to the reference PUSCH to calculate the power headroom of the PUSCH of the PHR or other channels that need to be reported, and report the calculated power headroom as the power headroom of the PUSCH of the PHR that needs to be reported.

[0206] In addition, in one embodiment of the present disclosure, based on the fact that the PHR report content includes the above-mentioned related second power parameter, the UE may selectively add an identifier of each TRP to the PHR report content.

[0207] That is, in one embodiment of the present disclosure, when the UE reports the PHR, the report content may include the associated second power parameter. In another embodiment of the present disclosure, when the UE reports the PHR, the report content may include the associated second power parameter plus an identifier of each TRP.

The base station then triggers a PHR report for at least two TRPs corresponding to each carrier based on the power control parameters and the report trigger condition.

Furthermore, in the method provided by the embodiment of the present disclosure, the power control parameters include not only power control parameters corresponding to a carrier but also power control parameters corresponding to TRPs on the carrier, and the PHR report trigger condition includes not only trigger conditions based on the power control parameters corresponding to a carrier but also trigger conditions based on the power control parameters corresponding to TRPs on the carrier, thereby enhancing the configuration of the power control parameters and the PHR report trigger condition.

[0209] In the embodiment of the present disclosure, when reporting PHR, various options are added to the report content, enriching the report content without increasing the amount of report data. At the same time, in the embodiment of the present disclosure, when reporting PHR, the TRP identifier is also reported, so that the base station can reliably know the TRP corresponding to the reported PHR, thereby supporting dynamic scheduling under different conditions on different channels, realizing accurate power control, and ensuring effective allocation of network resources.

[0223] Here, for the explanation related to steps 1101 to 1104, please refer to the explanation of the above embodiment, and detailed explanation will be omitted in the embodiment of the present disclosure.

[0224] As described above, in a power headroom reporting method provided by an embodiment of the present disclosure, a UE receives power control parameters for at least one TRP corresponding to at least one carrier and a PHR report trigger condition corresponding to the at least one TRP transmitted from a base station. The base station then triggers a PHR report for at least two TRPs corresponding to each carrier based on the power control parameters and the report trigger condition. As can be seen from this, an embodiment of the present disclosure provides a PHR reporting method for a multi-TRP scenario. Furthermore, in the method provided by the embodiment of the present disclosure, the power control parameters include not only power control parameters corresponding to a carrier but also power control parameters corresponding to TRPs on the carrier, and the PHR report trigger condition includes not only trigger conditions based on the power control parameters corresponding to a carrier but also trigger conditions based on the power control parameters corresponding to TRPs on the carrier, thereby enhancing the configuration of the power control parameters and the PHR report trigger condition.

[0225] In the embodiment of the present disclosure, when reporting PHR, various options are added to the report content, enriching the report content without increasing the amount of report data. At the same time, in the embodiment of the present disclosure, when reporting PHR, the TRP identifier is also reported, so that the base station can reliably know the TRP corresponding to the reported PHR, thereby supporting dynamic scheduling under different conditions on different channels, realizing accurate power control, and ensuring effective allocation of network resources.

[0226] FIG. 12 is a schematic flowchart of a power headroom report reporting method provided by an embodiment of the present disclosure, which is applied to a base station. As shown in FIG. 12, the power headroom report reporting method may include the following steps 1201 to 1205.

[0227] Step 1201: Send configuration information to the UE.

[0228] Step 1202: Send power control parameters supporting one or more TRPs corresponding to at least one carrier to a UE.

[0229] Step 1203: Send PHR reporting trigger conditions corresponding to one or more TRPs to the UE.

[0230] Step 1204: Set / instruct the UE to use a sorting rule for sorting each TRP.

[0231] Step 1205: receive a PHR report of each TRP corresponding to each carrier sent from the UE;

[0232] Here, for the explanation related to steps 1201 to 1206, please refer to the explanation of the above embodiment, and detailed explanation will be omitted in the embodiment of the present disclosure.

[0233] As described above, in a power headroom reporting method provided by an embodiment of the present disclosure, a UE receives power control parameters for at least one TRP corresponding to at least one carrier and a PHR report trigger condition corresponding to the at least one TRP transmitted from a base station. The base station then triggers a PHR report for at least two TRPs corresponding to each carrier based on the power control parameters and the report trigger condition. As can be seen from this, an embodiment of the present disclosure provides a PHR reporting method for a multi-TRP scenario. Furthermore, in the method provided by the embodiment of the present disclosure, the power control parameters include not only power control parameters corresponding to a carrier but also power control parameters corresponding to TRPs on the carrier, and the PHR report trigger condition includes not only trigger conditions based on the power control parameters corresponding to a carrier but also trigger conditions based on the power control parameters corresponding to TRPs on the carrier, thereby enhancing the configuration of the power control parameters and the PHR report trigger condition.

[0234] In the embodiment of the present disclosure, when reporting PHR, various options are added to the report content, enriching the report content without increasing the amount of report data. At the same time, in the embodiment of the present disclosure, when reporting PHR, the TRP identifier is also reported, so that the base station can reliably know the TRP corresponding to the reported PHR, thereby supporting dynamic scheduling under different conditions on different channels, realizing accurate power control, and ensuring effective allocation of network resources.

[0235] In addition, for a situation where a UE supports reporting of PHRs of single or multiple TRPs on one carrier, there is a special case when the UE reports the PHRs of the TRPs, namely, a situation where the UE triggers reporting of a single TRP corresponding to each carrier.

[0236] Specifically, in one embodiment of the present disclosure, the UE can specifically determine, based on the dynamic TRP scheduling indication information sent from the base station, whether to report a PHR of one TRP corresponding to each carrier to the base station or to report a PHR of each TRP corresponding to each carrier to the base station.

[0237] Specifically, in one embodiment of the present disclosure, the dynamic TRP scheduling indication information indicates whether the UE's current transmission is in a single-TRP transmission state or a multi-TRP transmission state. Here, if the dynamic TRP scheduling indication information indicates that the UE's current transmission is in a single-TRP transmission state, the UE may report a PHR of one TRP corresponding to each carrier to the base station. If the dynamic TRP scheduling indication information indicates that the UE's current transmission is in a multi-TRP transmission state, the UE may report a PHR of each TRP corresponding to each carrier to the base station.

[0238] The following examples in Figures 13 to 16 illustrate a special case, namely, "UE triggers reporting of a single TRP corresponding to each carrier."

[0239] FIG. 13 is a schematic flowchart of a power headroom report reporting method provided by an embodiment of the present disclosure, which is applied to a base station. As shown in FIG. 13, the power headroom report reporting method may include the following steps 1301 to 1304.

[0240] Step 1301: Send configuration information to the UE.

[0241] Step 1302: Send power control parameters supporting one or more TRPs corresponding to at least one carrier to a UE.

[0242] Step 1303: Send PHR reporting trigger conditions corresponding to one or more TRPs to the UE.

[0243] Here, for the explanation related to steps 1301 to 1303, please refer to the above embodiment, and detailed explanation will be omitted in the embodiment of the present disclosure.

[0244] Step 1304: receive a PHR report of one TRP corresponding to each carrier sent from the UE;

[0245] Here, in one embodiment of the present disclosure, the report content of the PHR of one TRP reported by the UE to the base station may include an associated first power parameter.

[0246] where the relevant first power parameter is: In response to power backoff being configured on the carrier, reporting a maximum power that one TRP can transmit on the carrier after the power backoff; In response to the PUSCH being configured on the carrier and the UE transmitting the actual PUSCH, one TRP reports a power headroom after transmitting the actual PUSCH; In response to the PUSCH being configured on the carrier and the UE transmitting the actual PUSCH, reporting a power headroom after one TRP transmits a reference PUSCH; In response to a PUSCH being configured on the carrier and the UE not transmitting an actual PUSCH, reporting a power headroom after one TRP transmits a reference PUSCH; In response to the PUCCH being configured on the carrier and the UE transmitting the actual PUCCH, reporting a power headroom after one TRP transmits the actual PUCCH; In response to a PUCCH being configured on the carrier and the UE transmitting an actual PUCCH, reporting a power headroom after one TRP transmits a reference PUCCH; In response to a PUCCH being configured on the carrier and the UE not transmitting an actual PUCCH transmission, reporting a power headroom after one TRP transmits a reference PUCCH; In response to the SRS being configured on the carrier and the UE transmitting the actual SRS, one TRP reports a power headroom after transmitting the actual SRS; In response to the SRS being configured on the carrier and the UE transmitting the actual SRS, reporting a power headroom after one TRP transmits a reference SRS; In response to the SRS being configured on the carrier and the UE not transmitting the actual SRS, reporting a power headroom after one TRP transmits a reference SRS; In response to the PRACH being configured on the carrier and the UE transmitting the true PRACH, reporting a power headroom after one TRP transmits the true PRACH; In response to the PRACH being configured on the carrier and the UE transmitting the true PRACH, reporting a power headroom after one TRP transmits a reference PRACH; In response to a PRACH being configured on the carrier and the UE not transmitting an actual PRACH, reporting a power headroom after one TRP transmits a reference PRACH; and reporting a power back-off value for the UE.

[0247] In one embodiment of the present disclosure, the report content may include any one of the above. In another embodiment of the present disclosure, the report content may include any combination of the above.

[0248] The above "transmitting actual PUSCH" and "transmitting reference PUSCH" will be explained using PUSCH as an example (similar to PUCCH / SRS / PRACH).

[0249] In one embodiment of the present disclosure, the "power headroom after transmitting an actual PUSCH" refers to the power headroom of the PUSCH after an actual transmission is performed on the PUSCH.

[0250] In one embodiment of the present disclosure, the "power headroom after transmitting a reference PUSCH" means that when a PUSCH is not actually transmitted but the power headroom of the PUSCH needs to be reported, the UE may determine a reference PUSCH based on an instruction from the network, use the transmission format and transmission parameters corresponding to the reference PUSCH to calculate the power headroom of the PUSCH of the PHR or other channels that need to be reported, and report the calculated power headroom as the power headroom of the PUSCH of the PHR that needs to be reported.

[0251] In addition, in one embodiment of the present disclosure, based on the PHR report content including the above-mentioned related first power parameter, the UE may selectively add a TRP identifier to the PHR report content.

[0252] That is, in one embodiment of the present disclosure, when the UE reports the PHR, the report content may include the associated first power parameter. In another embodiment of the present disclosure, when the UE reports the PHR, the report content may include the associated first power parameter+TRP identifier.

[0253] As described above, in a power headroom reporting method provided by an embodiment of the present disclosure, a UE receives power control parameters for at least one TRP corresponding to at least one carrier and a PHR report trigger condition corresponding to the at least one TRP transmitted from a base station. The base station then triggers a PHR report for at least two TRPs corresponding to each carrier based on the power control parameters and the report trigger condition. As can be seen from this, an embodiment of the present disclosure provides a PHR reporting method for a multi-TRP scenario. Furthermore, in the method provided by the embodiment of the present disclosure, the power control parameters include not only power control parameters corresponding to a carrier but also power control parameters corresponding to TRPs on the carrier, and the PHR report trigger condition includes not only trigger conditions based on the power control parameters corresponding to a carrier but also trigger conditions based on the power control parameters corresponding to TRPs on the carrier, thereby enhancing the configuration of the power control parameters and the PHR report trigger condition.

[0254] In the embodiment of the present disclosure, when reporting PHR, various options are added to the report content, enriching the report content without increasing the amount of report data. At the same time, in the embodiment of the present disclosure, when reporting PHR, the TRP identifier is also reported, so that the base station can reliably know the TRP corresponding to the reported PHR, thereby supporting dynamic scheduling under different conditions on different channels, realizing accurate power control, and ensuring effective allocation of network resources.
