Channel quality information feedback techniques

26-45. (canceled)

User equipment (UE), comprising:

• a circuitry coupled to a radio frequency (RF) receiver, the circuitry to derive a channel quality indicator (CQI) index for a frequency band of an orthogonal frequency-division multiple access (OFDMA) wireless communication system, the circuitry to derive the CQI index based on a channel state information (CSI) reference resource of a shared wireless downlink channel, a first three orthogonal frequency-division multiplexing (OFDM) symbols of the CSI reference resource to be occupied by control signals;
• and
• an RF transmitter coupled to the circuitry, the RF transmitter to transmit electromagnetic signals representing the CQI index on a wireless uplink channel.

User equipment (UE), comprising:

• a circuitry coupled to a radio frequency (RF) receiver, the circuitry to report a channel quality indicator (CQI) index for an orthogonal frequency-division multiple access (OFDMA) frequency band, the circuitry to derive the CQI index based on a channel state information interference measurement (CSI-IM) resource;
• and
• an RF transmitter coupled to the circuitry, the RF transmitter to transmit the CQI index over a wireless uplink channel.

User equipment (UE), comprising:

• a circuitry coupled to a radio frequency (RF) receiver, the circuitry to report a channel quality indicator (CQI) index for an orthogonal frequency-division multiple access (OFDMA) frequency band, the circuitry to derive the CQI index based on a channel state information (CSI) reference resource of a downlink shared channel based on an assumption that no resource elements of the CSI reference resource are allocated to an enhanced physical downlink control channel (EPDCCH) or a physical broadcast channel (PBCH);
• and
• an RF transmitter coupled to the circuitry, the RF transmitter to transmit the CQI index over a wireless uplink channel.
