Transmission of deferred sps harq feedback coinciding with current pucch

A method of wireless communication at a user equipment (UE), comprising:

• determining to transmit physical uplink control channel (PUCCH) semi-persistent scheduling (SPS) hybrid automatic repeat request (HARD) acknowledgment (ACK) (HARQ-ACK) feedback in response to a received semi-persistently scheduled physical downlink shared channel (PDSCH);
• determining that transmission of the SPS PUCCH HARQ-ACK feedback would overlap with a downlink (DL) symbol, wherein the transmission of the SPS PUCCH HARQ-ACK feedback is deferred to another uplink (UL) symbol if the transmission of the SPS PUCCH HARQ-ACK feedback overlaps with the DL symbol;
• and
• transmitting, based on the determination that the SPS PUCCH HARQ-ACK feedback would overlap with a DL symbol, a deferred SPS PUCCH HARQ-ACK feedback in one of a next set of available UL symbols or concurrently with a PUCCH HARQ-ACK feedback transmission in a next dynamically scheduled PUCCH after the DL symbol based on a deferred feedback configuration configured to define PUCCH content.

An apparatus for wireless communication at a base station, comprising:

• a memory;
• and
• at least one processor coupled to the memory and configured to:
• provide, to a user equipment (UE), a deferred feedback configuration to define physical uplink control channel (PUCCH) content, the deferred feedback configuration configured to defer transmission of PUCCH semi-persistent scheduling (SPS) hybrid automatic repeat request (HARQ) acknowledgment (ACK) (HARQ-ACK) feedback in response to a semi-persistently scheduled physical downlink shared channel (PDSCH), wherein transmission of the PUCCH SPS HARQ-ACK feedback is deferred if the transmission collides with a downlink (DL) symbol or a subsequent PUCCH HARQ-ACK feedback transmission in a next dynamically scheduled PUCCH after the DL symbol;
• transmit, to the UE, the semi-persistently scheduled PDSCH based on the deferred feedback configuration;
• and
• monitor for a deferred transmission of the PUCCH SPS HARQ-ACK feedback based on the deferred feedback configuration.
