Method and system for a simplified user group selection scheme with finite-rate channel state information feedback for FDD multiuser MIMO downlink transmission |
摘要 |
<p>Certain embodiments of the invention may be found in a method and system for a simplified user group selection scheme with finite-rate channel state information feedback for frequency division duplex (FDD) multiuser multiple-input-multiple-output (MIMO) downlink transmission. Aspects of the method may include selecting, from a plurality of users, a first user having a channel gain that is greater than a channel gain corresponding to a remaining portion of the plurality of users. At least a second user may be selected from a portion of the remaining portion of the plurality of users. The selected at least the second user has a channel direction that may be approximately orthogonal to that of the first user. The channel gain may be defined by a quantized channel gain. A quantized channel direction of the selected first user may be determined for the selecting the at least the second user.
