Abstract
Piggybacked acknowledgement/non-acknowledgement (PAN) bits in unreliable bit positions of a modulated symbol are swapped with data bits located in more reliable bit positions. In addition, a power offset value may be applied to the symbols containing the PAN bits.
Claims21
A method for use in a wireless transmit/receive unit (WTRU), the method comprising:
- generating a stream of bits for transmission, the stream of bits including data bits and piggybacked acknowledgement/non-acknowledgement (PAN) bits;
- interleaving the stream of bits to create an interleaved stream of bits;
- modulating the interleaved stream of bits to create a plurality of symbols,
- wherein each symbol represents a plurality of bits and has a least significant bit (LSB) position, and
- wherein no PAN bits are present in the LSB position of each of the plurality of symbols;
- and
- transmitting the plurality of symbols.

A wireless transmit/receive unit (WTRU), the WTRU comprising:
- a processor configured to generate a stream of bits for transmission, the stream of bits including data bits and piggybacked acknowledgement/non-acknowledgement (PAN) bits;
- an interleaver configured to interleave the stream of bits to create an interleaved stream of bits;
- a modulator configured to modulate the interleaved stream of bits to create a plurality of symbols,
- wherein each symbol represents a plurality of bits and has a least significant bit (LSB) position, and
- wherein no PAN bits are present in the LSB position of each of the plurality of symbols;
- and
- a transmitter configured to transmit the plurality of symbols.

A method for use in a wireless transmit/receive unit (WTRU), the method comprising:
- generating data bits and piggybacked acknowledgement/non-acknowledgement (PAN) bits;
- generating a plurality of symbols based on the data bits and the PAN bits,
- wherein each symbol of the plurality of symbols represents a plurality of bits and has a least significant bit (LSB) position, and
- wherein no PAN bits are present in the LSB position of each of the plurality of symbols;
- and
- transmitting the plurality of symbols.
