Abstract:
Disclosed are methods, systems and devices for channel state information feedback to facilitate, for example, high-performance beamforming or precoding in multiple input multiple output (MIMO) systems. One example method includes performing multiple transmissions of a channel measurement report on multiple transmission occasions. Another example method includes performing multiple receptions of a channel measurement report on multiple reception occasions, where the multiple receptions at a network node correspond to multiple transmissions from a wireless device. In both exemplary methods, a timing of the multiple transmissions is based on at least one of a number of the multiple transmission occasions, a time gap between adjacent transmission occasions of the multiple transmission occasions, and one or more timeslots that include the multiple transmission occasions.
