Fig. 2 is a first schematic flowchart of a resource adjustment method according to an embodiment of the present application. As shown in fig. 2, the following detailed implementation is included.
In 201, LTE transmit power of a terminal device is obtained, where the terminal device is an LTE FDD + NR TDD terminal device.
In 202, the maximum NR equivalent electric field strength under the condition that the SAR index does not exceed the standard is determined according to the acquired LTE transmission power.
In 203, the NR transmission power and/or NR uplink ratio of the terminal device is adjusted based on the maximum NR equivalent electric field strength.
The total transmit power of an LTE FDD + NR TDD terminal device is typically 26 dBm.
For LTE FDD + NR TDD terminal devices, since LTE and NR are in different frequency bands and different antennas may be used, the SAR values radiated by LTE and NR are not equivalent, i.e. the SAR values brought by the same transmission power of LTE and NR are different.
In addition, for LTE, when the transmit power is greater than or equal to 23dBm, even if NR does not work, its SAR still faces the risk of exceeding standards, so to avoid SAR exceeding standards, the distribution of the total power generally needs to satisfy the following conditions: the LTE transmitting power is less than or equal to 23 dBm; the sum of the LTE transmitting power and the NR transmitting power is less than or equal to the total transmitting power.
In the resource adjustment method described in this embodiment, the LTE transmission power of the terminal device may be obtained first, and the LTE transmission power may be obtained through uplink power control. And then, the maximum NR equivalent electric field strength under the condition that the SAR index does not exceed the standard can be determined according to the obtained LTE transmitting power.
Preferably, the electric field strength EP corresponding to the LTE transmission power of the terminal device can be obtained in the existing mannerLTEThereafter, according to a predetermined EPLTEElectric field intensity E corresponding to SAR indexSARAnd determining the maximum NR equivalent electric field strength as the required maximum NR equivalent electric field strength under the limiting condition among the NR equivalent electric field strengths.
The limiting conditions may be: EPLTE+EPNR*DutyNR≤ESAR。
Among them, EPNRIndicates the electric field intensity, Duty, corresponding to the NR transmission powerNRIndicating NR uplink ratio, EPNR*DutyNRThe NR equivalent electric field strength is indicated.
Because the value of the SAR index is well defined, the electric field intensity E corresponding to the SAR index can be obtainedSARFurther, according to the above-mentioned limitation conditions, the maximum NR equivalent electric field intensity EP can be determinedNR*DutyNRThis is taken as the required maximum NR equivalent electric field strength.
Or before determining the maximum NR equivalent electric field strength under the condition that the SAR index is not out of standard according to the LTE transmission power of the terminal device, the maximum NR equivalent electric field strengths corresponding to different LTE transmission powers may be determined according to the above-mentioned limiting conditions, and the determined correspondence is recorded in the first storage table. Therefore, when the maximum NR equivalent electric field strength under the condition that the SAR index is not over standard needs to be determined according to the LTE transmitting power of the terminal equipment, the maximum NR equivalent electric field strength corresponding to the LTE transmitting power of the terminal equipment can be determined by inquiring the first storage table.
Different LTE transmission powers theoretically include all possible values of the LTE transmission power, but in consideration of the size of the occupied storage space, the table lookup speed, and the like, some typical values of the LTE transmission power are usually selected, and the correspondence between the values and the corresponding maximum NR equivalent electric field strengths is recorded in the first storage table, as shown in table one.

TABLE-corresponding relationship between LTE Transmission Power and maximum NR equivalent electric field intensity
As shown in table one, the maximum NR equivalent electric field strength corresponding to the LTE transmission power of 23dBm, 22dBm, …, 1dBm, and 0dBm can be determined respectively.
When the first storage table is queried according to the LTE transmission power of the terminal device, the LTE transmission power of the terminal device may not exist in the first storage table, and then one of the LTE transmission powers recorded in the first storage table that is closest to the LTE transmission power value of the terminal device may be selected, and the maximum NR equivalent electric field strength corresponding to the LTE transmission power is taken as the maximum NR equivalent electric field strength corresponding to the LTE transmission power of the terminal device.
Further, for each maximum NR equivalent electric field strength in the first storage table, a corresponding second storage table may be generated, where the second storage table records a correspondence relationship between different NR transmission powers and corresponding maximum NR uplink occupation ratios, and a product of an electric field strength corresponding to each NR transmission power and the corresponding maximum NR uplink occupation ratio is equal to the maximum NR equivalent electric field strength.
For example, for E shown in Table one22A second memory table may be generated as shown in table two.

Corresponding relation between table two NR transmitting power and maximum NR uplink ratio
Different NR transmit powers theoretically include all possible values of NR transmit power, but in consideration of the size of occupied storage space and table lookup speed, some typical values of NR transmit power, such as 26dBm and 25dBm shown in table two, are usually selected and recorded in the second storage table as a correspondence between the values and the corresponding maximum NR uplink ratios.

After the maximum NR equivalent electric field strength under the condition that the SAR index is not overproof is determined according to the LTE transmitting power of the terminal equipment, the NR transmitting power and/or the NR uplink occupation ratio of the terminal equipment can be adjusted based on the maximum NR equivalent electric field strength. Specifically, a second storage table corresponding to the maximum NR equivalent electric field strength may be determined first, and for convenience of description, the determined second storage table is referred to as a second storage table x, and then, the NR transmission power and/or the NR uplink duty ratio of the terminal device may be adjusted based on the second storage table x.
In addition, before adjusting the NR transmission power and/or NR uplink ratio of the terminal device based on the second storage table x, it may be determined whether an adjustment condition is met, and if so, the NR transmission power and/or NR uplink ratio of the terminal device is adjusted.
The NR transmitting power of the terminal equipment can be obtained, the maximum NR uplink ratio corresponding to the NR transmitting power of the terminal equipment is determined by inquiring the second storage table x, then the NR uplink ratio of the terminal equipment can be obtained, the NR uplink ratio of the terminal equipment is compared with the maximum NR uplink ratio corresponding to the inquired NR transmitting power of the terminal equipment, and if the NR uplink ratio of the terminal equipment is greater than the maximum NR uplink ratio corresponding to the NR transmitting power of the terminal equipment, the adjustment condition can be determined to be met.
After determining that the adjustment condition is met, the NR transmit power and/or NR uplink ratio of the terminal device may be adjusted.
The adjustment methods include but are not limited to:
1) determining NR transmitting power corresponding to the NR uplink occupation ratio of the terminal equipment by inquiring the second storage table x, and adjusting the NR transmitting power of the terminal equipment to the NR transmitting power corresponding to the NR uplink occupation ratio of the terminal equipment;
2) and determining the maximum NR uplink ratio corresponding to the NR transmitting power of the terminal equipment by inquiring the second storage table x, and adjusting the NR uplink ratio of the terminal equipment to the maximum NR uplink ratio corresponding to the NR transmitting power of the terminal equipment.
When the second storage table x is queried, the NR uplink ratio of the terminal device may not exist in the second storage table x, and then one of the NR uplink ratios recorded in the second storage table x that is closest to the NR uplink ratio value of the terminal device may be selected, and the NR transmission power corresponding to the NR uplink ratio is used as the NR transmission power corresponding to the NR uplink ratio of the terminal device.
Similarly, when the second storage table x is queried, the NR transmission power of the terminal device may not exist in the second storage table x, and then one of the NR transmission powers recorded in the second storage table x that is closest to the NR transmission power of the terminal device may be selected, and the maximum NR uplink occupation ratio corresponding to the NR transmission power is taken as the maximum NR uplink occupation ratio corresponding to the NR transmission power of the terminal device.
After the NR transmission power of the terminal device is adjusted, if the NR transmission power of the terminal device is smaller than the predetermined threshold, the NR connection may be disconnected in order to ensure the working quality, and the specific value of the predetermined threshold may be determined according to actual needs.
