Abstract: Methods, systems, and devices for wireless communication are described. A network entity may schedule uplink resource allocations across multiple cells by defining selection criteria for the uplink resource allocations in which to transmit a channel state information (CSI) report. For example, a user equipment (UE) may receive a control signal from the network entity, which may schedule the UE to transmit the CSI report in an uplink resource allocation on a component carrier in a carrier aggregation configuration. In some examples, the UE may transmit the CSI report by multiplexing the CSI report in uplink resource allocations on multiple component carriers. In some examples, the CSI report may be transmitted in an uplink resource allocation on a smallest component carrier index. Accordingly, the defined selection criteria may allow for more efficient procedures at the UE, which may result in increased efficiency and decreased overhead.

Abstract: This disclosure provides systems, methods, and apparatus, including computer programs encoded on computer storage media, for handling hybrid automatic repeat request (HARQ) processes with discontinuous reception (DRX) operations. A user equipment (UE) may use timers to maintain an ON duration in DRX. The UE may receive, via downlink control information (DCI), an indication of a feedback transmission opportunity (TxOP) for a HARQ process. The UE may activate a timer at the end of the TxOP regardless of whether the UE transmits feedback in the TxOP to ensure that the UE remains active. In some implementations, a base station may provide the UE with multiple opportunities to transmit a feedback message. The UE may reactivate a timer after each feedback TxOP for the same HARQ process or may activate the timer after the first feedback TxOP and may refrain from activating the timer after subsequent feedback TxOPs for the HARQ process.
