Abstract:
1. A Long Term Evolution (LTE) protocol evolved Node-B (eNB) for dynamic modulation change while generating a Media Access Control (MAC) Protocol Data Unit (PDU) in a LTE wireless network, comprising: a transceiver system configured to receive a packet and a Channel Quality Indicator (CQI) from a User Equipment (UE), wherein the CQI is associated with a modulation scheme and coding rate; and a processing system coupled to the transceiver system and configured to determine whether padding is needed in the MAC PDU, if padding is needed, select a slower modulation scheme and coding rate than the associated modulation scheme and coding rate specified by the CQI, wherein the selected slower modulation scheme and coding rate are selected so as to eliminate padding in the MAC PDU, and transmit the MAC PDU using the selected slower modulation scheme and coding rate.
