Method and apparatus for performing dynamic statistical period adjustment regarding rate adaption

An apparatus for performing dynamic statistical period adjustment regarding rate adaption (RA), applicable to a hardware wireless communications device, the apparatus comprising:

• a hardware processing circuit, positioned in the hardware wireless communications device, configured to control operations of the hardware wireless communications device and collect respective transmission results of multiple data packets to perform parallel processing, wherein the parallel processing comprises statistical period control and RA control, wherein:
• the statistical period control comprises:
• the hardware processing circuit determines a first loop index reaches a monitored period threshold, wherein the monitored period threshold corresponds to a monitored period, the first loop index represents a monitored packet count, and the monitored period threshold indicates the monitored period and represents a first predetermined time length;
• in response to the first loop index reaching the monitored period threshold, the hardware processing circuit performs first transmitting (TX) information statistics in the monitored period;
• the hardware processing circuit calculates variance of TX information statistics results, wherein the TX information statistics results comprise first statistics results of the first TX information statistics;
• and
• according to the variance, the hardware processing circuit selectively adjusts a statistical period threshold for performing the RA control;
• wherein the first statistics results of the first TX information statistics represent a series of packet error rates (PERs), and the variance represents variance of the series of PERs;
• and
• the RA control comprises:
• the hardware processing circuit determines a second loop index reaches the statistical period threshold, wherein the statistical period threshold corresponds to a statistical period, the second loop index represents a statistical packet count, and the statistical period threshold indicates the statistical period and represents a second predetermined time length;
• in response to the second loop index reaching the statistical period threshold, the hardware processing circuit performs second TX information statistics in the statistical period;
• and
• according to one or more second statistics results of the second TX information statistics, the hardware processing circuit performs the RA, wherein the one or more second statistics results of the second TX information statistics represent a latest PER;
• wherein the statistical period control dynamically adjusts the statistical period of the RA control, to enhance transmission efficiency of the wireless communications device.
