Abstract
Transmitting, in a wireless local area network (WLAN), a second punctured coded bit sequence generated by puncturing coded data using a second puncturing pattern, wherein the coded data has previously been punctured using a first puncturing pattern to generate a first punctured coded bit sequence transmitted in the WLAN. The second puncturing pattern is different than the first puncturing pattern to cause at least some bits of the coded data that were omitted in the first punctured coded bit sequence to be included in the second punctured coded bit sequence.
Claims20
A method comprising:
- transmitting, in a wireless local area network (WLAN), a second punctured coded bit sequence generated by puncturing coded data using a second puncturing pattern, wherein the coded data has previously been punctured using a first puncturing pattern to generate a first punctured coded bit sequence transmitted in the WLAN, the second puncturing pattern being different than the first puncturing pattern to cause at least some bits of the coded data that were omitted in the first punctured coded bit sequence to be included in the second punctured coded bit sequence, and wherein the second punctured coded bit sequence is transmitted as part of a data unit that includes a header field including an index indicating that the second punctured coded bit sequence is a first re-transmission.
A method comprising:
- transmitting, in a wireless local area network (MAN), a second punctured coded bit sequence generated by puncturing coded data using a second puncturing pattern, wherein the coded data has previously been punctured using a first puncturing pattern to generate a first punctured coded bit sequence transmitted in the WLAN, the second puncturing pattern being different than the first puncturing pattern such that at least some bits of the coded data that were omitted in the first punctured coded bit sequence are included in the second punctured coded bit sequence, and wherein the second punctured coded bit sequence is transmitted as part of a data unit that includes a header field including an indicator that the second puncturing pattern was used to generate the second punctured coded bit sequence.
A method of transmitting hybrid automatic repeat request (HARQ) re-transmissions in a wireless local area network (WLAN), comprising:
- transmitting, in the WLAN, a data unit including a re-transmission punctured coded bit sequence generated by puncturing coded data using a retransmission puncturing pattern, wherein the coded data has previously been punctured using a different puncturing pattern to generate a different punctured coded bit sequence transmitted in the WLAN,
- the data unit including a header field that includes a HARQ retransmission index indicating which re-transmission the re-transmission punctured coded bit sequence corresponds to.
An encoder for encoding data for transmission in a wireless local area network (WLAN), the encoder being configured to:
- apply binary convolution coding (BCC) to an input bit sequence using a first generator polynomial and a second generator polynomial to respectively generate a first BCC sequence of coded bits and a second BCC sequence of coded bits;
- combine the coded bits from the first BCC sequence and the coded bits from the second BCC sequence subject to a first puncturing pattern to generate a first punctured coded bit sequence for the transmission in the WLAN;
- and
- combine the coded bits from the first BCC sequence and the coded bits from the second BCC sequence subject to a second puncturing pattern that is different that the first puncturing pattern to generate a second punctured coded bit sequence for the transmission in the WLAN that includes at least some coded bits that are omitted from the first punctured coded bit sequence, wherein the second punctured coded bit sequence is transmitted as part of a data unit that includes a header field including an index indicating that the second punctured coded bit sequence is a first re-transmission.
