Fig. 3 is a flowchart of a method for selecting resources according to the second embodiment of the present invention, which is specifically described when the target slot position is the target receiving position based on the first embodiment of the present invention, wherein the specific content of step S210 is substantially the same as that of step S110 in the first embodiment, so that details are not repeated in this embodiment, and as shown in fig. 3, the method includes:
s210, acquiring original signal information of the terminal in a specified period.
S220, determining target receiving positions of the original signal information in the resource detection window and target signal information at the target receiving positions.
Specifically, the controller determines each target receiving position according to the receiving signal time slot in the receiving signal, that is, the controller sequentially takes each receiving position as the target receiving position according to the designated period and then the receiving positions from the near to the far according to the receiving signal time slot under the designated period.

Specifically, when the target time slot position is the target receiving position, the controller needs to determine that the reference received signal power is greater than a preset power threshold before determining the effective time slot position in the resource selection window according to the target time slot position and the target signal information, and since only the received signal information greater than the preset power threshold will affect the data sent by the terminal, the preset power threshold is set in advance inside the controller by the user according to the terminal performance. For example, in the specified period, the reference received signal power corresponding to the received position a is-112 dBm and the reference received signal power corresponding to the received position B is-72 dBm, the preset power threshold set by the user is-102 dBm, the controller takes the received position a as the target time slot position, the controller obtains the reference received signal power of the received position a as-112 dBm and is smaller than the preset power threshold-102 dBm, at this time, the controller selects the next received position according to the received signal time slot, the subsequent effective resource determination operation is not performed on the received position a, then the controller takes the received position B as the target time slot position, the controller obtains the reference received signal power of the received position B as-72 dBm and is larger than the preset power threshold, and the controller determines the subsequent effective time slot position of the received position B.
S240, determining the effective time slot position in the resource selection window according to the target receiving position and the target signal information.
For example, when the specified period is 20ms, if 5 receiving positions exist in the specified period, the controller sequentially takes the 5 receiving positions as target receiving positions, the controller determines that the reference received signal power corresponding to the target receiving position is greater than the preset power threshold, the controller determines the effective time slot position according to the target receiving position and the target signal information in the resource selection window, when the controller selects the receiving position B as the target receiving position, the controller determines the candidate time slot position according to the receiving position B and the receiving signal period, namely, the receiving signal time slot and the receiving signal period of the receiving position B are added to obtain the candidate time slot position, and when the candidate time slot position is located in the resource selection window, the controller takes the candidate time slot position as the ineffective time slot position; the controller will process each target receiving position in turn to determine each invalid time slot position, and finally, the controller will exclude all the invalid time slot positions in the resource selection window, and the remaining time slot positions are used as valid time slot positions.
S250, judging whether the number of the effective time slot positions is larger than a preset number threshold, if so, executing S260, otherwise, executing S270.
The preset number threshold is set by a user according to the communication protocol of the terminal, and the purpose of the preset number threshold is to ensure the communication requirement of the terminal, so that the remaining effective time slot positions can also meet the communication requirement of the terminal after the invalid time slot positions are eliminated by the terminal.
Preferably, when the target time slot position is the target receiving position, the number of the effective time slot positions is obtained; and determining that the number of the effective time slot positions is larger than a preset number threshold.
Specifically, when the target time slot position is the target receiving position, the controller excludes all the invalid time slot positions in the resource selection window, and then determines the number of valid time slot positions, that is, the controller sums the remaining valid time slot positions in the resource selection window.
S260, taking the resource corresponding to the effective time slot position as a target resource.
Specifically, the controller compares the sum value of the remaining effective time slot positions in the resource selection window with a preset number threshold, when the number of the effective time slot positions is greater than the preset number threshold, it is indicated that the target resources corresponding to the effective time slot positions are sufficient to ensure the normal communication requirements of the terminal, the controller takes the resources corresponding to the effective time slot positions as target resources, and then the terminal can select the target resources as the resources for transmitting data.
S270, updating the preset power threshold according to the excluded resources.
Preferably, when the number of the effective time slot positions is determined to be smaller than a preset number threshold, the target signal information corresponding to the ineffective time slot positions is used as the elimination resource; taking the minimum received signal power in the excluded resource as the update power; updating the preset power threshold according to the updated power to obtain an updated preset power threshold; and updating the effective time slot position in the resource selection window according to the updated preset power threshold.
Specifically, when the number of the effective time slot positions is determined to be smaller than the preset number threshold by the controller, it is indicated that the target resources corresponding to the effective time slot positions are insufficient to ensure normal communication of the terminal, at this time, the target signal information corresponding to the ineffective time slot positions is taken as the rejection resources, the reference signal received power in the rejection resources is taken as the update power, that is, the controller updates the power threshold according to the minimum value of the reference signal received power in the rejection resources, for example, the reference signal received power-72 dBm of the receiving position B in the rejection resources is the minimum power, at this time, the controller updates the preset power threshold according to the reference signal received power of the receiving position B, that is, -72dbm+3dbm, the updated preset power threshold is-69 dBm, and then the candidate time slot positions corresponding to the receiving position B at this time are not rejected by being taken as the ineffective time slot resources because the power is lower than the updated preset power threshold, the terminal guarantees that the effective time slot positions are sufficient in number to meet the communication requirements in a mode of the minimum value of the reference signal received power in the rejection resources, at this time slot positions, at this time, the controller can update the preset power threshold is updated by the preset power threshold according to the reference signal received power of the receiving position B, namely 72dBm, at the effective time slot positions corresponding to the effective time slot positions, and the effective time slot positions can be increased by the effective time slot positions in the mode, and the effective time slot positions corresponding to the effective time slots corresponding to the effective time positions are not be guaranteed to be guaranteed, and the effective time slot positions can be met, and when the effective position and corresponding position and has a threshold is met.
According to the technical scheme, the original signal information with the specified period is acquired in the resource detection window, so that the workload and the time consumption are reduced, the burden of the terminal is lightened, the effective time slot position is determined in the resource selection window through the target time slot position and the target signal information, then the effective time slot position is used as the target resource, the terminal effectively eliminates occupied resources, further the working efficiency is improved, the limitation of the preset power threshold value and the preset quantity threshold value is further increased when the target receiving position is eliminated in the resource selection window, and the communication requirement of the terminal when data is transmitted is better ensured.
