Claim:
1. A method for adjusting uplink data transfers from a mobile device to a serving cell of an enhanced NodeB (eNodeB) of a wireless network based on estimation of uplink (UL) interference, the method comprising: by the mobile device: estimating an UL block error rate (BLER) for UL transmission to the serving cell; estimating an UL transmit signal power level received at the serving cell; estimating an UL signal-to-interference-plus-noise ratio (SINR) based on the UL BLER and a symbol error probability (SEP); estimating an UL interference-plus-noise at the serving cell based on the SINR; determining a set of supportable UL data transmission parameters at a target UL BLER based on the UL interference-plus-noise and the UL SINR; and sending to the eNodeB a power headroom report (PHR) and/or a buffer status report (BSR), the PHR having modified values that underrepresents an amount of power headroom and/or the BSR having modified values that underrepresents an amount of pending data, wherein the PHR and/or the BSR are based at least in part on the set of supportable UL data transmission parameters, and wherein the eNodeB sends grants to the mobile device including transport block size (TBS) and/or modulation and coding scheme (MCS) values based on the PHR and the BSR.
