Abstract
Methods, systems, and devices for wireless communications are described. A base station may configure uplink resources within a slot to enable a user equipment (UE) to transmit an acknowledgment (ACK) feedback message for multiple downlink semi-persistent scheduling (SPS) configurations. For example, the base station may transmit an additional configuration to the UE that indicates uplink resources that the UE can use to transmit acknowledgment feedbacks for multiple downlink messages received according to the SPS configurations, where the UE determines which uplink resource to use based on a number of acknowledgment information bits to be transmitted for the acknowledgment feedback message. For example, if the number of acknowledgment information bits is below a threshold value, the UE may use a first uplink resource configured by the base station. Alternatively, if the number of acknowledgment information bits is above the threshold value, the UE may use a second uplink resource.
