Abstract:
1. A method for wireless communication, comprising: determining, at a user equipment (UE), a channel quality indicator (CQI) using a set of precoding matrices that is assumed by the UE, the set of precoding matrices assumed by the UE being for a set of time-frequency resources available for data transmission to the UE and the UE selecting random precoding matrices for the set of time-frequency resources, the UE assuming the set of precoding matrices for the set of time-frequency resources based on a base station randomly or pseudo-randomly selecting a set of precoding matrices for the data transmission to the UE, wherein the set of precoding matrices assumed by the UE is different from the set of precoding matrices randomly or pseudo-randomly selected by the base station for the data transmission to the UE; and sending the CQI from the UE to the base station.
