Abstract:
Various embodiments are generally directed to improved channel quality information feedback techniques. In one embodiment, for example, an evolved node B (eNB) may comprise a processor circuit, a communication component for execution by the processor circuit to receive a channel quality index for a physical downlink shared channel (PDSCH), the channel quality index associated with a defined reference resource, and a selection component for execution by the processor circuit to select a modulation and coding scheme (MCS) for transmission over the PDSCH of user equipment (UE) data in one or more resource blocks, the selection component to compensate for a difference between a cell-specific reference signal (CRS) overhead of the defined reference resource and a CRS overhead of the one or more resource blocks when selecting the MCS. Other embodiments are described and claimed.
