Adaptation techniques in MIMO

摘要

A method of the multiple input multiple output feedback is disclosed. In accordance with an embodiment of the invention, the multiple input multiple output feedback method includes a receiver receiving a reference signal from a base station and calculating a signal to interference and noise ratio from the received reference signal. The method further includes determining a modulation and coding scheme based on the signal to interference and noise ratio and a receiver type.

1. A system for link adaptation in MIMO systems, comprising:
a receiver circuit of a linear receiver type or a non-linear receiver type; a plurality of antenna ports configured to couple to a plurality of antennas, respectively, and to receive signals thereat, wherein the receiver circuit is configured to determine a signal to interference and noise ratio (SINR) of one or more received signals; a determiner logic configured to determine a mapping of signal to interference and noise ratio (SINR) to modulation and coding scheme (MCS), wherein the mapping is dependent on the receiver type of the receiver, wherein for at least one SINR the MCS for a linear receiver type is different than the MCS for a non-linear receiver type; and a selection logic configured to select a modulation and coding scheme (MCS).
