1. A method for wireless communication at a user equipment (UE), comprising:
receiving, from a base station, a control message indicating a resource configuration for uplink and downlink transmissions;
determining an uplink buffer threshold for a modem buffer of the UE based at least in part on the resource configuration;
transmitting, to the base station, a feedback request message in accordance with a feedback request rate, the feedback request message requesting that the base station provide feedback for at least one previously transmitted uplink packet based at least in part on a comparison of a sum to the uplink buffer threshold, wherein the sum is of a first amount of previously transmitted uplink data and a second amount of scheduled uplink data, and wherein the previously transmitted uplink data and the scheduled uplink data are stored in the modem buffer; and
retransmitting the at least one previously transmitted uplink packet, prior to receiving a feedback response message corresponding to the feedback request message requesting that the base station provide feedback for the at least one previously transmitted uplink packet, wherein a copy of the at least one previously transmitted uplink packet is stored in the modem buffer.
