In MU-MIMO scenarios, a transmitting node (700) receives feedback on a feedback channel from a receiving node (1200) regarding a channel between the transmitting and receiving nodes (700, 1200). The feedback also includes preferences of the receiving node (1200). However, the feedback may not always be useful. For example, the receiving node (1200) may indicate a preferred rank in the feedback that the transmitting node (700) cannot accommodate. To address such issues, mechanisms for the transmitting node (700) to convey its preferences to the receiving node (1200) are proposed. The receiving node (1200), with such knowledge, can provide more useful feedback information to the transmitting node (700). |
