PAPR and inter-cell interference reduction

A wireless communication device for wireless communication, comprising:

• a memory;
• and
• one or more processors configured to:
• apply one or more spreading sequences to a set of modulation symbols of a data set to generate spread modulation symbols, wherein, when applying the one or more spreading sequences, the one or more processors are configured to perform spreading based at least in part on multiplying a codeword by a cell-specific mask sequence;
• apply a scrambling sequence to the spread modulation symbols to generate a set of scrambled symbols, wherein a spreading sequence, of the one or more spreading sequences, is shorter in length than the scrambling sequence;
• and
• transmit a waveform based at least in part on the set of scrambled symbols.

A non-transitory computer-readable medium storing one or more instructions for wireless communication, the one or more instructions comprising:

• one or more instructions that, when executed by one or more processors of a wireless communication device, cause the one or more processors to:
• apply one or more spreading sequences to a set of modulation symbols of a data set to generate spread modulation symbols, wherein the one or more instructions, that cause the one or more processors to apply the one or more spreading sequences, cause the one or more processors to perform spreading based at least in part on multiplying a codeword by a cell-specific mask sequence;
• apply a scrambling sequence to the spread modulation symbols to generate a set of scrambled symbols, wherein a spreading sequence, of the one or more spreading sequences, is shorter in length than the scrambling sequence;
• and
• transmit a waveform based at least in part on the set of scrambled symbols.

An apparatus for wireless communication, comprising:

• means for applying one or more spreading sequences to a set of modulation symbols of a data set to generate spread modulation symbols, wherein the means for applying the one or more spreading sequences comprises means for performing spreading based at least in part on multiplying a codeword by a cell-specific mask sequence;
• means for applying a scrambling sequence to the spread modulation symbols to generate a set of scrambled symbols, wherein a spreading sequence, of the one or more spreading sequences, is shorter in length than the scrambling sequence;
• and
• means for transmitting a waveform based at least in part on the set of scrambled symbols.
