Patent ID: 8837519

Claim:
A method of a mobile communication device for improving uplink transmission, comprising: receiving a transmission including a commanded modulation and coding scheme (MCS) having a first robustness; transmitting a transmission of an encoded data block in accordance with the commanded MCS; determining that no satisfactory response to the transmission of the encoded data block in accordance with the commanded MCS was received within a predetermined period of time; determining an alternative MCS having a second robustness different from the commanded MCS having the first robustness when determining that no response to the transmission of the encoded data block in accordance with the commanded MCS was received with the predetermined period of time, the commanded MCS and the alternative MCS are in a same MCS family; and preemptively transmitting from a mobile communication device a transmission of the encoded data block in accordance with the alternative MCS, determining that a response to the transmission of the encoded data block in accordance with the alternative MCS was received; transmitting a subsequent transmission of another encoded data block in accordance with the commanded MCS, wherein the second robustness of the alternative MCS is more robust than the first robustness of the commanded MCS, and wherein the commanded MCS includes at least one of Gaussian filtered Minimum Shift Keying (GMSK) as a modulation scheme and Eight Phase Shift Keying (8-PSK) as a modulation scheme, or both.
