Various embodiments are generally directed to improved channel quality information feedback techniques. In one embodiment, for example, an apparatus for a base station is provided that includes a radio interface and a processor coupled to the radio interface. The processor is configured to receive a channel quality indicator (CQI) index, wherein the CQI index is based on a channel state information (CSI) reference resource, further wherein a first three orthogonal frequency-division multiplexing (OFDM) symbols of the CSI reference resource are occupied by control signals, select a modulation and coding scheme (MCS) for a physical downlink shared channel (PDSCH) based on the CQI index, and cause transmission of the PDSCH based on the selected MCS via the radio interface. Other embodiments are described and claimed.

Channel quality information feedback techniques

Some demonstrative embodiments include apparatuses, devices, systems and methods of communicating a PPDU including a training field. For example, an Enhanced Directional Multi-Gigabit (DMG) (EDMG) wireless communication station may be configured to determine one or more Orthogonal Frequency Division Multiplexing (OFDM) Training (TRN) sequences in a frequency domain based on a count of one or more 2.16 Gigahertz (GHz) channels in a channel bandwidth for transmission of an EDMG PPDU including a TRN field; generate one or more OFDM TRN waveforms in a time domain based on the one or more OFDM TRN sequences, respectively, and based on an OFDM TRN mapping matrix, which is based on a count of the one or more transmit chains; and transmit an OFDM mode transmission of the EDMG PPDU over the channel bandwidth, the OFDM mode transmission comprising transmission of the TRN field based on the one or more OFDM TRN waveforms.
