Claim 23:
24. An apparatus for wireless communication at a user equipment (UE), comprising:
at least one processor; and
at least one memory coupled with the at least one processor, with instructions stored in the at least one memory, the instructions being executable by the at least one processor, individually or in any combination, to cause the apparatus to:
receive, from a base station, a control message indicating a resource configuration for uplink and downlink transmissions;
determine an uplink buffer threshold for a modem buffer of the UE based at least in part on the resource configuration;
transmit, 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
retransmit 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.
