As described in the background art, how to determine the priority of CSI reporting with reference to new measurement parameters is a technical problem to be solved urgently.
The technical scheme of the invention determines the values of the CSI reporting coefficients according to the types of the measurement parameters contained in the channel state information report, the values of the CSI reporting coefficients corresponding to different types of measurement parameters have a preset size relationship, namely the value of the CSI reporting coefficient corresponding to L1-RSRP is more than or equal to the value of the CSI reporting coefficient corresponding to L1-RSRQ, and the value of the CSI reporting coefficient corresponding to L1-RSRQ is more than or equal to the value of the CSI reporting coefficient corresponding to L1-SINR; the priority level of the status information report is obtained through the calculation of the CSI report coefficient value, so that the priority of the better status information report is higher, and the communication quality between the user equipment and the base station is ensured.
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below.
Fig. 1 is a flowchart of a method for determining priority of csi reporting according to an embodiment of the present invention.
The method can be used on the user equipment side, and the method for determining the priority of the channel state information report shown in fig. 1 can include the following steps:
step S101: determining the type of the measurement parameter contained in the channel state information report, wherein the type of the measurement parameter is selected from a type set, the type set comprises L1-RSRP, and the type set further comprises L1-RSRQ and/or L1-SINR;
step S102: determining a CSI reporting coefficient value according to the type of the measurement parameter, wherein the CSI reporting coefficient value corresponding to L1-RSRP is greater than or equal to the CSI reporting coefficient value corresponding to L1-RSRQ, and the CSI reporting coefficient value corresponding to L1-RSRQ is greater than or equal to the CSI reporting coefficient value corresponding to L1-SINR;
step S103: and calculating the priority level of the channel state information report by using the value of the CSI reporting coefficient, wherein the smaller the value of the CSI reporting coefficient is, the higher the priority level is.
In a specific implementation, the measurement parameters included in the channel state information report may be selected from L1-RSRP and L1-RSRQ; can also be selected from L1-RSRP and L1-SINR; can also be selected from L1-RSRP, L1-RSRQ and L1-SINR.
The type of measurement parameter included in the channel state information report may be one or more. Preferably, the channel state information report contains only one type of measurement parameter.
In a specific implementation of step S102, the value of the CSI reporting coefficient may be determined according to the type of the measurement parameter included in the CSI report. Further, in step S103, the priority level of the CSI report may be calculated using the value of the CSI report coefficient.
Specifically, the value of the CSI reporting coefficient corresponding to L1-RSRP is greater than or equal to the value of the CSI reporting coefficient corresponding to L1-RSRQ; the value of the CSI reporting coefficient corresponding to the L1-RSRP is greater than or equal to the value of the CSI reporting coefficient corresponding to the L1-SINR; the value of the CSI reporting coefficient corresponding to L1-RSRQ is larger than or equal to the value of the CSI reporting coefficient corresponding to L1-SINR. And the smaller the value of the CSI reporting coefficient, the higher the priority level.
In this embodiment, L1-RSRP represents Reference Signal Receiving Power (RSRP) of physical layer 1; L1-RSRQ represents Reference Signal Receiving Quality (RSRQ) of physical layer 1; L1-SINR represents the Signal to Interference plus Noise Ratio (SINR) of physical layer 1.
More specifically, due to the difference between the L1-SINR and the L1-RSRQ in the calculation manner, the L1-RSRQ calculation may be obtained by using RSRP and RSSI measured on different Resource Elements (REs), and the L1-SINR calculation may be obtained by using RSRP and RSSI measured on the same RE, so that the L1-SINR accuracy is higher, and the value of the CSI reporting coefficient corresponding to L1-RSRQ is greater than or equal to the value of the CSI reporting coefficient corresponding to L1-SINR.
Then in case the value of the CSI reporting coefficient corresponding to L1-RSRP is greater than the value of the CSI reporting coefficient corresponding to L1-RSRQ, the priority level of the CSI report containing L1-RSRP is lower than the priority level of the CSI report containing L1-RSRQ; when the value of the CSI reporting coefficient corresponding to L1-RSRQ is larger than that corresponding to L1-SINR, the priority level of the CSI report containing L1-RSRQ is lower than that of the CSI report containing L1-SINR.
It should be noted that, as to a specific manner in which the ue interacts with the base station using the priority level of the CSI report, reference may be made to the prior art, and the embodiment of the present invention is not limited thereto.
The method and the device determine the values of the CSI reporting coefficients according to the types of the measurement parameters contained in the channel state information report, wherein the values of the CSI reporting coefficients corresponding to different types of measurement parameters have a preset size relationship, namely the value of the CSI reporting coefficient corresponding to L1-RSRP is greater than or equal to the value of the CSI reporting coefficient corresponding to L1-RSRQ, and the value of the CSI reporting coefficient corresponding to L1-RSRQ is greater than or equal to the value of the CSI reporting coefficient corresponding to L1-SINR; the priority level of the status information report is obtained through the calculation of the CSI report coefficient value, so that the priority of the better status information report is higher, and the communication quality between the user equipment and the base station is ensured.
In an embodiment of the present invention, the priority level P of the csi report may be calculated by using the following formula:
p ═ M × Ncell × Ms × y + Ncell × Ms × k + Ms × c + s; wherein, M represents a constant coefficient, and Ncells represents the maximum number of serving cells; ms represents a maximum number of the CSI reporting configurations; y represents a coefficient determined according to a bearer channel and periodicity of transmission; k represents the CSI reporting coefficient; c represents a sequence number of the serving cell; s represents a configuration sequence number of the CSI report; the constant coefficient M is a fixed value, or the constant coefficient M is the number of selectable values of the CSI reporting coefficient.
Wherein, the value of the CSI reporting coefficient M is selected and determined from a plurality of selectable values.
In this embodiment, the constant coefficient M may be the number of selectable values of the CSI reporting coefficient. The constant coefficient M may also be a fixed value of 2.
Specifically, the set of types includes L1-RSRP and L1-RSRQ. And under the condition that the value of the CSI reporting coefficient corresponding to the L1-RSRP is greater than the value of the CSI reporting coefficient corresponding to the L1-RSRQ, the number of the values of the CSI reporting coefficients is 3, and the constant coefficient M is 3. And under the condition that the value of the CSI reporting coefficient corresponding to the L1-RSRP is equal to the value of the CSI reporting coefficient corresponding to the L1-RSRQ, the number of the values of the CSI reporting coefficients is 2, and the constant coefficient M is 2.
It will be understood that, as regards the coefficient y, it takes the following values: when the CSI report bearing channel is PUSCH and is sent out aperiodically (aperiodic), the value of the coefficient y is 0; when the CSI report bearer channel is PUSCH and Semi-persistent (Semi-persistent) is sent, the value of the coefficient y is 1; when the CSI report bearer channel is PUCCH and Semi-persistent (Semi-persistent) transmission, the value of the coefficient y is 2; when the CSI report bearer channel is PUCCH and is periodically (periodically) transmitted, the value of the coefficient y is 3.

In this embodiment, the first preset value may be 0, the second preset value may be 1, and the third preset value may be 2.

In this embodiment, the first preset value may be 0, and the second preset value may be 1.
Thus, the priority level P of the channel state information report may be calculated using the following formula:
p is 2 × Ncell × Ms × y + Ncell × Ms × k + Ms × c + s; when the CSI report contains L1-RSRQ or L1-RSRP, the CSI report coefficient k is 0; and when the CSI report does not contain L1-RSRQ nor L1-RSRP, the CSI report coefficient k is 1.

step S302: if the type of the measurement parameter is L1-RSRP, determining that the value of the CSI reporting coefficient is a fifth preset value, otherwise, determining that the value of the CSI reporting coefficient is a sixth preset value, wherein the sixth preset value is larger than the fifth preset value, and the fifth preset value is larger than the fourth preset value.
In this embodiment, the fourth preset value may be 0, the fifth preset value may be 1, and the sixth preset value may be 2.
Thus, the priority level P of the channel state information report may be calculated using the following formula:
p is 3 × Ncell × Ms × y + Ncell × Ms × k + Ms × c + s; when the CSI report contains L1-SINR, the CSI report coefficient k is 0; when the CSI report contains L1-RSRP, the CSI report coefficient k is 1; and when the CSI report does not contain L1-SINR and L1-RSRP, the CSI report coefficient k is 2.
