Abstract: Methods, systems, and devices for wireless communication are described. Generally, the described techniques provide for establishing rules for scheduling downlink data transmissions and flow control feedback for the downlink data transmissions to avoid confusion at a base station and a user equipment (UE). In one example, when flow control feedback from a UE is disabled for a downlink data transmission, the UE may still operate according to a timing for reporting flow control feedback for the downlink data transmission. In this example, the UE may drop (e.g., refrain from decoding) other downlink data transmissions based on the timing for reporting flow control feedback. In another example, when flow control feedback from a UE is disabled for a downlink data transmission, other downlink data transmissions to the UE may be scheduled according to one or more rules to avoid confusion.

Abstract: A sidelink user equipment (UE) limits sensing of received sidelink communications during a sensing window. The UE selects resources for a future transmission from a resource pool that is based on the sensed received sidelink communications. The UE also sends the future transmission on the selected resources. Limiting sensing may result from reducing a maximum distance between reservations to less than 32 logical slots. Limiting sensing may be sensing with a reduced sensing duty cycle with discontinuous sensing or sensing for a period of time in response to a trigger. The UE may perform partial sensing for periodic traffic, and limit sensing for aperiodic traffic.
