HARQ feedback configuration techniques for broadband wireless communication networks

An at least one non-transitory computer-readable storage medium comprising a set of instructions that, in response to being executed at a user equipment (UE), cause the UE to:

• identify a value contained in downlink control information (DCI) received from a base station (BS) consisting of exactly two-bits,
• the value indicating a physical uplink control channel (PUCCH) format, a PUCCH resource, and a HARQ feedback payload size for a HARQ feedback;
• identify hybrid automatic repeat request (HARQ) feedback to be provided to the BS via a physical uplink control channel (PUCCH) of a primary cell of the UE according to a PUCCH format that can accommodate a greater number of HARQ feedback bits than can be accommodated by a PUCCH format 3;
• determine, based on the value, a PUCCH resource to be used to provide the HARQ feedback;
• and
• generate control information according to the PUCCH format for transmission to the BS via the PUCCH resource, the control information to comprise the HARQ feedback.

A User equipment (UE), comprising:

• baseband circuitry to generate baseband signals comprising control information to be provided to a base station (BS), the baseband circuitry to:
• identify a set of downlink data transmissions for which to include hybrid automatic repeat request (HARQ) feedback in the control information, the set of downlink data transmissions to comprise transmissions via two or more aggregated carriers;
• and
• identify a value contained in downlink control information (DCI) received from the BS consisting of exactly two-bits,
• the value indicating a physical uplink control channel (PUCCH) format, a PUCCH resource, and a HARQ feedback payload size for a HARQ feedback;
• based on a determination that a number of bits of the HARQ feedback payload size to be comprised in the HARQ feedback exceeds a number of HARQ feedback bits that can be accommodated by a physical uplink control channel (PUCCH) format 3:
• construct the control information according to a second PUCCH format that can accommodate a greater number of HARQ feedback bits than can be accommodated by the PUCCH format 3;
• and
• identify, based on the value, the PUCCH resource to provide the control information;
• radio frequency (RF) circuitry to generate RF signals based on the baseband signals;
• and
• circuitry to amplify the RF signals for transmission by at least one RF antenna.
