Abstract: Wireless communications systems and methods related to dynamically triggering aperiodic CSI reporting are disclosed. A UE may determine whether a condition is satisfied for triggering upon receipt of a signal from a BS. The condition may be based on a decoding status of the signal. In some examples, the UE may explicitly request a CSI resource signal (e.g., CSI-RS, CSI-IM, or both) from the BS when the condition is met. The explicit request may be included in a modified ACK/NACK field, regardless of whether an ACK or NACK is transmitted. The BS may respond with a CSI resource signal. In other examples, the BS may wait to respond with a CSI resource signal until a threshold number of requests are received from the UE. In other examples, the BS may track a number of NACKs from the UE instead of relying upon an explicit request.

Different sets of weights may be used for different incoming beams. The RIS controller may be trained with a pair of transmitter and a receiver to identify/generate the codebook for an optimized set of weights under specific situations.
