Method of arranging packets in a wireless communication system and related device
View Patent ↗A method of arranging a packet in a wireless communication system includes a preamble sequence and a data sequence. The preamble sequence includes a legacy training field (L-TF), a legacy signal field (L-SIG), a very high throughput signal field (VHT-SIG), a very high throughput short training field (VHT-STF) and at least one very high throughput long training field (VHT-LTF). The method includes generating a first VHT-SIG field and a second VHT-SIG field according to the VHT-SIG field; and arranging the L-TF field, the L-SIG field, the first VHT-SIG field, the VHT-STF field, one of the at least one VHT-LTF fields, the second VHT-SIG field and the rest of the at least one VHT-LTF fields in a predetermined sequence.
1. A method of arranging a packet for a transmitter in a wireless communication system to assist with a data decoding process, the method comprising: generating, by a processor of the transmitter, a first very high throughput signal (VHT-SIG) field and a second VHT-SIG field; and arranging, by the processor, a legacy training field (L-TF), a legacy signal field (L-SIG), the first VHT-SIG field, a very high throughput short training field (VHT-STF), one of at least one very high throughput long training fields (VHT-LTF), the second VHT-SIG field and rest of the at least one VHT-LTF fields in a predetermined sequence as a preamble sequence of the packet; wherein the second VHT-SIG field comprises individual information corresponding to each of a plurality of users.
2. The method claim 1 , wherein generating the first VHT-SIG field and the second VHT-SIG field according to the VHT-SIG field is achieved by dividing the VHT-SIG field into the first VHT-SIG field and the second VHT-SIG field.
3. The method claim 1 , wherein the first VHT-SIG field comprises common information corresponding to the plurality of users.
4. The method claim 1 , wherein the individual information comprises a length of a physical layer convergence procedure (PLCP) protocol data unit (PSDU) field for each user.
5. The method claim 1 , wherein the data sequence comprises a service field, a physical layer convergence procedure (PLCP) service data unit (PSDU) field, a tail field and a pad field, and the method further comprises:
arranging the service field, the PSDU field, the tail field and the pad field sequentially.
6. A transmitter of a wireless communication system for performing the method of claim 1 .
7. A method of arranging a packet for a transmitter in a wireless communication system to assist with a data decoding process, the method comprising: generating, by a processor of the transmitter, a first very high throughput signal (VHT-SIG) field and a second VHT-SIG field; and arranging, by the processor, a legacy training field (L-TF), a legacy signal field (L-SIG), the first VHT-SIG field, a very high throughput short training field (VHT-STF), at least one very high throughput long training fields (VHT-LTF) and the second VHT-SIG field in a predetermined sequence as a preamble sequence of the packet; wherein the second VHT-SIG field comprises individual information corresponding to each of a plurality of users.
8. The method claim 7 , wherein generating the first VHT-SIG field and the second VHT-SIG field according to the VHT-SIG field is achieved by dividing the VHT-SIG field into the first VHT-SIG field and the second VHT-SIG field.
9. The method claim 7 , wherein the first VHT-SIG field comprises common information corresponding to the plurality of users.
10. The method claim 7 , wherein the individual information comprises a length of a physical layer convergence procedure (PLCP) protocol data unit (PSDU) field for each user.
11. The method claim 7 , wherein the data sequence comprises a service field, a physical layer convergence procedure (PLCP) service data unit (PSDU) field, a tail field and a pad field, and the method further comprises:
arranging the service field, the PSDU field, the tail field and the pad field sequentially.
12. A transmitter of a wireless communication system for performing the method of claim 7 .
