Discrete fourier transform-spread (DFT-S) based interlace physical uplink control channel (PUCCH) with user multiplexing

An apparatus comprising:

• one or more processors configured, individually or in any combination, to:
• generate a first communication signal by:
• block-spreading a first block of information symbols based on a first block-spreading code from a set of block-spreading codes associated with user multiplexing to generate a first block of spread information symbols;
• performing a discrete Fourier transform (DFT) on the first block of spread information symbols to generate a frequency signal;
• and
• mapping the frequency signal to a set of resource blocks (RBs);
• and
• a transceiver configured to:
• communicate, with a first wireless communication device using a frequency interlace in a frequency spectrum, the first communication signal including the first block of information symbols spread across the set of RBs within the frequency interlace based on the first block-spreading code.

A non-transitory computer-readable medium having program code recorded thereon, the program code comprising:

• code for causing a first wireless communication device to generate a first communication signal by:
• block-spreading a first block of information symbols based on a first block-spreading code from a set of block-spreading codes associated with user multiplexing to generate a first block of spread information symbols;
• performing a discrete Fourier transform (DFT) on the first block of spread information symbols to generate a frequency signal;
• and
• mapping the frequency signal to a set of resource blocks (RBs);
• and
• code for causing the first wireless communication device to communicate, with a second wireless communication device using a frequency interlace in a frequency spectrum, the first communication signal including the first block of information symbols spread across the set of RBs within the frequency interlace based on the first block-spreading code.
