Abstract: Embodiments for providing fast modulation and coding scheme adaptation for LTE regardless of transmission using single-user multiple-input and multiple-output (SU-MIMO) or multiple-user multiple-input and multiple-output are generally described herein. In some embodiments, channel state information reference signals are sent to user equipment by a node. First channel quality indication feedback based on the channel state information reference signals is received from the user equipment. Physical downlink shared channel data and demodulation reference signals are transmitted using a first modulation and coding scheme based on the first channel quality indication feedback. Second channel quality indication feedback based on measurements performed by the user equipment on the demodulation reference signals is received by a node. Physical downlink shared channel data is transmitted using a second modulation and coding scheme based on the second channel quality indication feedback.

Abstract: Embodiments of the present disclosure describe techniques and configurations for handling interference measurements in a wireless communication network. An apparatus may include computer-readable media having instructions and processors coupled with the computer-readable media and configured to execute the instructions to identify, for a serving eNB, a neighboring eNB for which signal interference measurements are to be performed by one or more wireless devices served by the serving eNB, and request that the neighboring eNB transmit typical interference signals within data units which are configured for, and may or may not have, a scheduled physical downlink shared channel transmission. The wireless devices may be configured to perform the signal interference measurements based at least in part on the typical interference signals, which may include non-zero-power signals or zero-power signals. Other embodiments may be described and claimed.
