Channel state information feedback for flexible uplink control signaling

A method for wireless communication at a network entity, comprising:

• allocating, to a user equipment (UE), uplink control resources for transmitting a channel state information report in a slot, wherein the channel state information report comprises a plurality of channel state information feedback components, and wherein the plurality of channel state information feedback components:
• a channel state information reference signal resource indicator associated with a first quantity of bits,
• a rank indicator associated with a second quantity of bits,
• a precoding matrix indicator associated with a third quantity of bits, and
• a channel quality indicator associated with a fourth quantity of bits;
• receiving, from the UE, a single encoded packet comprising the plurality of channel state information feedback components over the uplink control resources, wherein the single encoded packet comprises a predetermined number of bits including one or more padding bits, and wherein a quantity of the one or more padding bits is based at least in part on the rank indicator;
• and
• decoding the single encoded packet.

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

• one or more memories storing processor-executable code;
• and
• one or more processors coupled with the one or more memories and individually or collectively operable to execute the code to cause the UE to:
• receive an allocation of uplink control resources for transmitting a channel state information report, wherein the channel state information report comprises a plurality of channel state information feedback components, and wherein the plurality of channel state information feedback components comprise:
• a channel state information reference signal resource indicator associated with a first quantity of bits,
• a rank indicator associated with a second quantity of bits,
• a precoding matrix indicator associated with a third quantity of bits, and
• a channel quality indicator associated with a fourth quantity of bits;
• encode the plurality of channel state information feedback components into a single encoded packet, wherein the single encoded packet comprises a predetermined number of bits including one or more padding bits, and wherein a quantity of the one or more padding bits is based at least in part on the rank indicator;
• and
• transmit the single encoded packet over the uplink control resources during a single slot.
