Abstract: Described herein are apparatuses, systems and methods for adaptive downlink scheduling and link adaptation. The methods including, at a base station connected to a user equipment (“UE”), determining an initial modulation and coding scheme (“MCS”) for a plurality of subframes to be transmitted to the UE, wherein each MCS relates to a coding rate value for the subframes, determining an MCS pattern for the plurality of subframes based on the initial MCS, wherein an MCS for one of the subframes has a higher coding rate value than the initial MCS, and transmitting the plurality of subframes to the UE according to the MCS pattern.

Abstract: A device, system, and method perform an adaptive link adaptation. The method, at a user equipment (UE) connected to a Long Term Evolution (LTE) network via an evolved Node B (eNB), includes determining a type of wireless traffic being utilized by the UE based upon at least one application executed on the UE, the wireless traffic being one of a data only, a voice only, or a combination thereof. The method includes determining a block error rate (BLER) target value to be used in a channel state feedback operation associated with a link adaptation operation for a connection between the UE and the eNB.
