Channel state information and hybrid automatic repeat request feedback resource allocation in 5g

A user equipment (UE) for wireless communication, comprising:

• a memory;
• and
• one or more processors coupled to the memory, the memory and the one or more processors configured to:
• map channel state information (CSI) to first resource elements that are distributed in frequency, wherein the first resource elements are in a set of resources allocated on an uplink shared channel;
• map hybrid automatic repeat request (HARQ) feedback to second resource elements that are distributed in frequency, wherein the second resource elements are in the set of resources;
• wherein the second resource elements are reserved for the HARQ feedback and are different from the first resource elements;
• and
• transmit the CSI and the HARQ feedback on the uplink shared channel in accordance with the mappings.

A user equipment (UE) for wireless communication, comprising:

• an encoder component to encode uplink control information (UCI) and an uplink shared channel to generate an encoded communication, wherein the UCI includes at least one of channel state information (CSI) or hybrid automatic repeat request (HARQ) feedback;
• a modulator component to modulate the encoded communication onto a carrier signal;
• a UCI mapper component to map the UCI to resource elements of the uplink shared channel,
• wherein the CSI is mapped to first resource elements of the resource elements,
• wherein the HARQ feedback is mapped to second resource elements of the resource elements,
• wherein the second resource elements are reserved for the HARQ feedback and are different from the first resource elements;
• a discrete Fourier transform (DFT) component to perform DFT spreading of the uplink shared channel;
• a sub-band mapping component to map an output of the DFT spreading to sub-bands of an output signal;
• an inverse fast Fourier transform (IFFT) component to perform an IFFT on the output signal;
• and
• a transmitter component to transmit the output signal.
