    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.

    Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, from a base station, control signaling that may identify a configuration for channel state information reporting associated with both a first target block error rate and a second target block error rate. The UE may receive one or more reference signals associated with the channel state information reporting. Further, the UE may transmit, to the base station, the channel state information reporting that may include first channel state information for the first target block error rate and second channel state information for the second target block error rate. In some examples, each of the first channel state information and the second channel state information may be based on the received reference signals.

    Abstract: Methods, systems, and devices for wireless communications are described. An example method of wireless communication at a user equipment includes receiving a data transmission for each of a plurality of component carriers (CCs) over a wireless channel from a base station, wherein each data transmission is associated with a number of code block groups (CBGs). The method further includes identifying a feedback protocol to apply to the plurality of CCs and selecting a subset of the plurality of CCs for which to report feedback information for the CBGs based at least in part on the feedback protocol. The method may also include generating the feedback information based at least in part on the subset of the plurality of CCs and the feedback protocol and transmitting a feedback message that indicates the feedback information for the subset of the plurality of CCs of the wireless channel to the base station.
