A TCP ACK message segment may correspond to feedback for a respective portion of the quantity of data. The UE may generate and transmit a TCP ACK message associated with the quantity of data based on a transmission blanking pattern.

Abstract: A configuration to enable a UE to send data to a modem, from an AP, in the absence of an uplink grant from the modem. An apparatus receives data transmissions from a base station. The apparatus stores the data transmissions in a memory of the AP of the apparatus. The apparatus identifies, by the AP, an uplink grant based at least in part on a size of a modem buffer. The apparatus determines, by the application processor, whether to send data to the modem based at least in part on the identified uplink grant. The apparatus sends, by the AP, the data when the identified uplink grant exceeds a threshold.
