Abstract
A method may comprise receiving a first signal comprising first LDPC bits including systematic bits and parity bits and transmitting information indicating that the first signal was incorrectly received. A second signal comprising second LDPC bits may be received in response to the transmitting. The second signal may include LDPC bits according to a lifting size of an LDPC base graph.
Claims23
A method comprising:
- transmitting a first signal comprising first low density parity check (LDPC) bits, wherein the first LDPC bits include systematic bits and parity bits;
- receiving information indicating that the first signal was incorrectly received;
- and transmitting a second signal comprising second LDPC bits, in response to the information indicating that the first signal was incorrectly received, wherein the second signal includes LDPC bits according to a lifting size of an LDPC base graph.
A wireless transmit/receive unit (WTRU) comprising:
- a transmitter configured to transmit a first signal comprising first low density parity check (LDPC) bits, wherein the first LDPC bits include systematic bits and parity bits;
- a receiver configured to receive information indicating that the first signal was incorrectly received;
- and
- the transmitter configured to transmit a second signal comprising second LDPC bits, in response to the information indicating that the first signal was incorrectly received, wherein the second signal includes LDPC bits according to a lifting size of an LDPC base graph.
