[0002] In high-frequency communication, in order to obtain better communication performance, the transmission power is generally higher. The maximum radiated power (MPE) describes the maximum radiated power allowed by the user. When the terminal's transmission power exceeds a certain limit (for example, it is harmful to the human body), the terminal device will try to reduce the transmission power. However, the low-power transmission at this time may not meet the performance requirements of the terminal device, so the terminal device needs to report this event, that is, send an MPE report to the network device.

[0003] When the MPE report is fed back as L1 signaling, the priority of the CSI needs to be redefined, just like other Channel State Information (CSI) reports. However, there is currently no specific solution for the CSI priority after the introduction of the MPE report. Summary of the invention

Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0029] The high-level signaling mentioned in this application may be RRC signaling or MAC-CE signaling.

[0030] See also Figure 2 , Figure 2 A flow chart of a CSI report priority determination method provided in an embodiment of the present application is applied to Figure 1 The wireless communication system shown in FIG. Figure 2 As shown, the method includes the following steps.

[0031] S210: Obtain the type of measurement parameters in the CSI report, where the type of measurement parameters includes a layer 1 reference signal received power L1-RSRP, a layer 1 signal to interference plus noise ratio L1-SINR, and a maximum radiated power MPE report.

[0032] The measurement parameters in the CSI report or the types of measurement parameters in the CSI report may be configured by the network side through high-layer signaling.

[0033] In this application, the type of measurement parameter of the MPE report is introduced. The MPE report is used when the transmit power of the terminal device exceeds a certain limit (for example, exceeds the MPE) and the reduction of the transmit power may not meet the performance requirements. The terminal device reports the MPE report to inform the network device that its current transmit power is lower than the preset threshold, that is, the current beam is not suitable for transmission. The terminal device then reports the MPE report to the network device so that the network device can reconfigure a suitable beam for transmission according to the MPE report.

[0034] Optionally, the MPE report includes one or any combination of the following: P-MPE, the L1-RSRP, the virtual power headroom report PHR, the L1-SINR, the L1-RSRP affected by MPE, the L1-SINR affected by MPE, the CSI-RS resource indication CRI, the SSB resource indication SSBRI, and the estimated maximum uplink RSRP.

[0035] Among them, L1-RSRP represents the reference signal receiving power (RSRP) of the physical layer; L1-SINR represents the signal to interference plus noise ratio (SINR) of the physical layer.

[0036] Further, the L1-RSRP and L1-SINR are respectively the L1-RSRP and L1-SINR of the terminal device before the MPE report is generated or before the MPE is affected by MPE, that is, the L1-RSRP and L1-SINR are respectively the L1-RSRP and L1-SINR measured when the transmit power of the terminal device does not exceed MPE. The L1-RSRP affected by MPE and the L1-SINR affected by MPE are respectively the L1-RSRP and L1-SINR of the terminal device affected by MPE, that is, the L1-RSRP affected by MPE is the L1-RSRP measured when the transmit power of the terminal device exceeds MPE, and the L1-SINR affected by MPE is the L1-SINR measured when the transmit power of the terminal device exceeds MPE.

[0037] The power control maximum power fallback (Power Management Maximum Power Reduction, P-MPR) refers to the maximum power reduction performed to meet the applicable electromagnetic energy absorption requirements or the maximum power reduction performed to comply with the applicable electromagnetic energy absorption requirements when proximity detection is used; the virtual PHR represents the PHR calculated assuming that any one of PUCCH, PUSCH, and SRS is transmitted when any one of PUCCH, PUSCH, and SRS is not actually transmitted; the estimated maximum uplink RSRP represents an estimate of the uplink quality, measured in RSRP.

[0038] Exemplarily, the MPE report may include P-MPR and L1-RSRP.

[0039] Exemplarily, the MPE report may include a virtual power headroom report virtual PHR and L1-RSRP.

[0040] Exemplarily, the MPE report may include L1-RSRP, L1-SINR, MPE-affected L1-RSRP, and MPE-affected L1-SINR.

[0041] Exemplarily, the MPE report may include a virtual PHR.

[0042] Exemplarily, the MPE report may include P-MPE.

[0043] Exemplarily, the MPE report may include virtual PHR, CRI and / or SSBRI.

[0044] Exemplarily, the MPE report may include an estimated maximum uplink RSRP.

[0045] S220. Adjust the priority of the channel state information CSI report according to the MPE report.

[0046] The types of measurement parameters included in the CSI report may be one or more types, specifically, the types of measurement parameters included in the CSI report may include at least one of L1-RSRP, L1-SINR and MPE reports. The terminal device may calculate the priority of the CSI report according to the type of measurement parameters included in the CSI report, and report it according to the priority of the CSI. After receiving the CSI, the network device may adjust the scheduling and perform beam management-related work according to the CSI.

[0047] It should be noted that the specific manner in which the terminal device uses the priority level of the CSI report to interact with the network device can refer to the existing technology, and the embodiment of the present invention does not limit this.

[0048] Optionally, adjusting the priority of the channel state information CSI report according to the MPE report includes: determining a CSI reporting coefficient and / or a constant coefficient according to the type of the measurement parameter; and determining the priority of the CSI report according to the CSI reporting coefficient and / or the constant coefficient.

[0049] Among them, the present application determines the values ​​of the CSI reporting coefficient and the constant coefficient according to the type of measurement parameters contained in the CSI report. The values ​​of the CSI reporting coefficient and the constant coefficient corresponding to different types of measurement parameters have a preset size relationship, so that the better CSI report has a higher priority, thereby ensuring the communication quality between the terminal device and the network device.

[0050] Optionally, determining the priority of the CSI report according to the CSI reporting coefficient and / or the constant coefficient includes: determining the priority of the CSI report according to a preset priority formula, and the preset priority formula is: P = n*N cells *M s *y+N cells *M s *k+M s *c+s;

[0051] Wherein, n is the constant coefficient, and N cells is the maximum number of serving cells, the M s is the maximum number of configurations of the CSI report, y is a coefficient determined according to the bearer channel and the periodicity of transmission, k is the CSI reporting coefficient, c is the index of the serving cell, and s is the configuration index of the CSI report.

[0052] Specifically, y=0 can be used to indicate aperiodic CSI reporting carried on the physical uplink shared channel PUSCH, y=1 can be used to indicate semi-persistent CSI reporting carried on the PUSCH, y=2 can be used to indicate semi-persistent CSI reporting carried on the physical uplink control channel PUCCH, and y=3 can be used to indicate periodic CSI reporting carried on the PUCCH. cells Specifically, it can be the value of the high-level parameter maxNrofServingCells, the s can be the value of reportConfigID, and the M s Specifically, it may be the value of the high-level parameter maxNrofCSIReportConfigurations.

[0053] It should be noted that the name of the maximum number of serving cells specified in the 5G standard is maxNrofServingCells, the name of the configuration index of the CSI report is reportConfigID, and the name of the maximum number of configurations of the CSI report is maxNrofCSIReportConfigurations, but the names with the same meanings specified in other standards are also applicable to this application, that is, this application does not limit the names of these parameters.

[0054] In a possible embodiment, determining the CSI reporting coefficient and / or constant coefficient according to the type of the measurement parameter includes: when the type of the measurement parameter is the L1-RSRP or the L1-SINR, determining that the CSI reporting coefficient is a first value and the constant coefficient is a first preset value; when the type of the measurement parameter is not any one of the L1-RSRP, the L1-SINR, and the MPE report, determining that the CSI reporting coefficient is a second value and the constant coefficient is a first preset value; when the type of the measurement parameter is the MPE report, determining that the CSI reporting coefficient is a third value and the constant coefficient is a first preset value.

[0055] Among them, the first preset value may be 3.

[0056] In the embodiment of the present application, the constant coefficient is 3, and thus the priority level P of the CSI report can be calculated using the following preset priority formula: P = 3*N cells *M s *y+N cells *M s *k+M s *c+s.

[0057] Exemplarily, the first value may be 0, the second value may be 1, and the third value may be 2. If the CSI report includes any one of L1-RSRP and L1-SINR, the CSI reporting coefficient k is determined to be 0. When the CSI report does not include L1-RSRP, L1-SINR, or MPE report, the CSI reporting coefficient k is determined to be 1. When the CSI report includes an MPE report, the CSI reporting coefficient k is determined to be 2. Specifically, the priority of a CSI report including an MPE report is lower than the priority of a CSI report not including L1-RSRP or L1-SINR, and the priority of a CSI report including L1-RSRP or L1-SINR is higher than the priority of a CSI report not including L1-RSRP or L1-SINR.

[0058] Exemplarily, the first value may be 1, the second value may be 2, and the third value may be 0. If the CSI report includes any one of L1-RSRP and L1-SINR, the CSI reporting coefficient k is determined to be 1. When the CSI report does not include L1-RSRP, L1-SINR, or MPE report, the CSI reporting coefficient k is determined to be 2. When the CSI report includes an MPE report, the CSI reporting coefficient k is determined to be 0. Specifically, the priority of a CSI report including an MPE report is greater than the priority of a CSI report including L1-RSRP or L1-SINR, and the priority of a CSI report including L1-RSRP or L1-SINR is greater than the priority of a CSI report including neither L1-RSRP nor L1-SINR.

[0059] Exemplarily, the first value may be 0, the second value may be 1, and the third value may be 2. If the CSI report includes L1-RSRP and / or L1-SINR, the CSI reporting coefficient k is determined to be 0. When the CSI report does not include any of the L1-RSRP, L1-SINR, and MPE reports, the CSI reporting coefficient k is determined to be 1. When the CSI report includes an MPE report, the CSI reporting coefficient k is determined to be 2. Specifically, the priority of a CSI report including L1-RSRP or L1-SINR is greater than the priority of a CSI report that does not include L1-RSRP, L1-SINR, or MPE reports, and the priority of a CSI report that includes an MPE report is less than the priority of a CSI report that does not include any of the L1-RSRP, L1-SINR, and MPE reports.

[0060] In an embodiment of the present application, after the MPE report is introduced, the priority of the CSI report including the MPE report is calculated by adding k=2 and n=3, thereby providing a technical solution for determining the CSI priority after the MPE report is introduced.

[0061] In a possible embodiment, determining the CSI reporting coefficient and / or the constant coefficient according to the type of the measurement parameter includes:

[0062] When the type of the measurement parameter is any one of the L1-RSRP, the L1-SINR, and the MPE report, the CSI reporting coefficient is determined to be a first value and the constant coefficient is a second preset value; when the type of the measurement parameter is not the L1-RSRP, the L1-SINR, or any one of the MPE report is determined, the CSI reporting coefficient is a second value and the constant coefficient is a second preset value.

[0063] Among them, the first preset value can be 2.

[0064] In the embodiment of the present application, the constant coefficient is 2, and thus the priority level P of the CSI report can be calculated using the following preset priority formula: P = 2*N cells *M s *y+N cells *M s *k+M s *c+s.

[0065] Exemplarily, the first value may be 0, and the second value may be 1. If the CSI report includes any one of L1-RSRP, L1-SINR, and MPE reports, the CSI reporting coefficient k is determined to be 0. Specifically, when the CSI report includes L1-RSRP, the CSI reporting coefficient k is determined to be 0; when the CSI report includes L1-SINR, the CSI reporting coefficient k is determined to be 0; when the CSI report includes MPE report, the CSI reporting coefficient k is determined to be 0; when the CSI report does not include any one of L1-RSRP, L1-SINR, and MPE reports, that is, the CSI report does not include L1-RSRP, L1-SINR, or MPE reports, the CSI reporting coefficient k is determined to be 1. Specifically, the priority of a CSI report including any one of MPE reports, L1-RSRP, and L1-SINR is greater than the priority of a CSI report not including any of L1-RSRP, L1-SINR, and MPE reports.

[0066] Exemplarily, the first value may be 1, and the second value may be 0. If the CSI report includes any one of L1-RSRP, L1-SINR, and MPE reports, the CSI reporting coefficient k is determined to be 1. Specifically, when the CSI report includes L1-RSRP, the CSI reporting coefficient k is determined to be 1; when the CSI report includes L1-SINR, the CSI reporting coefficient k is determined to be 1; when the CSI report includes MPE reports, the CSI reporting coefficient k is determined to be 1; when the CSI report does not include any one of L1-RSRP, L1-SINR, and MPE reports, the CSI reporting coefficient k is determined to be 0. Specifically, the priority of a CSI report including any one of MPE reports, L1-RSRP, and L1-SINR is greater than the priority of any one of CSI reports that do not include L1-RSRP, L1-SINR, and MPE reports. In an embodiment of the present application, after the MPE report is introduced, the priority of the CSI report including the MPE report is calculated by redefining the value of the CSI reporting coefficient after the MPE report is added, thereby providing a technical solution for determining the CSI priority after the MPE report is introduced.

[0067] It can be understood that the first value, the second value and the third value in the present application can also be other values, as long as the conditions that the priority calculated by substituting the first value is less than the priority calculated by substituting the second value and the priority calculated by substituting the third value, and the priority calculated by substituting the second value is less than the priority calculated by substituting the third value under the same other conditions are met. The present application does not impose any restrictions on the first value, the second value and the third value.

[0068] It can be understood that the first preset value and the second preset value in the present application may also be other values, as long as the first preset value and the second preset value are greater than or equal to the number of values ​​of the CSI reporting coefficient k. The present application does not impose any restrictions on the first preset value and the second preset value.

[0069] It can be seen that the present application proposes a method for determining the priority of a CSI report, obtaining the type of measurement parameters in the CSI report, the types of measurement parameters including layer 1 reference signal received power L1-RSRP, layer 1 signal to interference plus noise ratio L1-SINR and maximum radiated power MPE report; determining the priority of the CSI report according to the type of measurement parameters, thereby providing a technical solution for determining the CSI priority after introducing the MPE report.

It is understandable that in order to realize the above functions, the network device includes a hardware structure and / or software module corresponding to each function.
