1. A method of wireless communication of a user equipment (UE), comprising: determining, by the UE, an observed bit rate based on uplink transmissions of the UE; estimating an available link capacity for the UE; selecting an estimate factor; and estimating an available uplink throughput for future uplink transmissions of the UE as a function of the observed bit rate, the estimated available link capacity, and the estimate factor, wherein the estimated available uplink throughput is a maximum of a product of the observed bit rate and a long term factor, a guaranteed bit rate, and a minimum bit rate, wherein the long term factor is a function of the estimate factor.
