Abstract

Claims (47)

1 . A control method of a wireless communication module, comprising:

receiving target end time information of a physical layer protocol data unit (PPDU), and estimating a symbol count of the PPDU according to the target end time information;

determining a duration of a packet extension of the PPDU;

refining an alignment setting comprising at least one of a padding factor, the duration of the packet extension, and the symbol count of the PPDU, wherein the padding factor indicates invalid data information of the PPDU;

generating the alignment setting comprising a final symbol count of the PPDU and the padding factor of the PPDU; and

aggregating a plurality of media access control protocol data units (MPDUs) to generate the PPDU according to the alignment setting;

wherein the control method further comprises:

subtracting one symbol from the symbol count of the PPDU to generate a new symbol count of the PPDU; and

the step of generating the alignment setting comprises:

generating the alignment setting comprising the new symbol count of the PPDU.

2 . A control method of a wireless communication module, comprising:

receiving target end time information of a physical layer protocol data unit (PPDU), and estimating a symbol count of the PPDU according to the target end time information;

determining a duration of a packet extension of the PPDU;

refining an alignment setting comprising at least one of a padding factor, the duration of the packet extension, and the symbol count of the PPDU, wherein the padding factor indicates invalid data information of the PPDU;

generating the alignment setting comprising a final symbol count of the PPDU and the padding factor of the PPDU; and

aggregating a plurality of media access control protocol data units (MPDUs) to generate the PPDU according to the alignment setting;

wherein the step of refining the alignment setting of the PPDU comprises:

determining the padding factor, the duration of packet extension, and the final symbol count of the PPDU to satisfy a nominal packet padding requirement of a receiver and a target end time requirement;

directly adjusting the padding factor to make the PPDU have more invalid data; and

the step of generating the alignment setting comprises:

generating the alignment setting comprising the final symbol count of the PPDU, a new duration of packet extension, and a new padding factor of the PPDU.

3 . The control method of claim 2 , wherein the padding factor is a pre-FEC (forward error correction) padding factor, the last symbol of a PPDU comprises a plurality of segments, and the step of directly adjusting the padding factor to make the PPDU have more invalid data comprises:

directly adjusting the padding factor to make a last symbol have at least one more segment(s) having invalid data.

4 . A circuitry of a wireless communication module, comprising:

a physical layer protocol data unit (PPDU) end time alignment module, configured to perform steps of:

receiving target end time information of a physical layer protocol data unit (PPDU), and estimating a symbol count of the PPDU according to the target end time information;

determining a duration of a packet extension of the PPDU;

generating the alignment setting comprising a final symbol count of the PPDU and the padding factor of the PPDU; and

an aggregation module, configured to perform steps of:

aggregating a plurality of media access control protocol data units (MPDUs) to generate the PPDU according to the alignment setting:

wherein the end time alignment module further subtracts one symbol from the symbol count of the PPDU to generate a new symbol count of the PPDU, and generates the alignment setting comprising the new symbol count of the PPDU.

5 . A circuitry of a wireless communication module, comprising:

a physical layer protocol data unit (PPDU) end time alignment module, configured to perform steps of:

receiving target end time information of a physical layer protocol data unit (PPDU), and estimating a symbol count of the PPDU according to the target end time information;

determining a duration of a packet extension of the PPDU;

refining an alignment setting comprising at least one of a padding factor, the duration of the packet extension, and the symbol count of the PPDU, wherein the padding factor indicates invalid data information of the PPDU; and

generating the alignment setting comprising a final symbol count of the PPDU and the padding factor of the PPDU; and

an aggregation module, configured to perform steps of:

aggregating a plurality of media access control protocol data units (MPDUs) to generate the PPDU according to the alignment setting;

wherein the step of refining the alignment setting of the PPDU comprises:

determining the padding factor, the duration of packet extension, and the final symbol count of the PPDU to satisfy a nominal packet padding requirement of a receiver and a target end time requirement;
