Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a control message that schedule a first uplink message via a first set of time resources and a second uplink message via a second set of time resources. The UE may refrain from transmitting at least a first portion of the first uplink message that is virtually overlapping (and physically non-overlapping) with the second uplink message (e.g., drop the first portion). In some aspects, the first portion of the first uplink message virtually overlaps with the second uplink message based on a time gap between the first uplink message and the second uplink message in the time domain being less than a threshold gap. The UE may then transmit the second uplink message, a second portion of the first uplink message that is virtually non-overlapping with the second uplink message, or both.

Abstract: Methods, systems, and devices for wireless communications are described. Generally, the described techniques provide for control of a reconfigurable intelligent surface (RIS) and for beam selection at a base station based on feedback from a user equipment (UE). In some examples, the feedback may be based on a variance threshold of a reference signal received power for a set of reference signals transmitted by the base station and associated with a beam directed toward a RIS. In some examples, the feedback may be based on a received power comparison between a probe or reference beam and a set of reference signals transmitted by the base station and associated with a beam directed toward a RIS. The base station and the UE may communicate via using the RIS or not using the RIS based on the feedback.

Abstract: Aspects of the present disclosure provide techniques to address the scenarios where some SRS symbols in a timeline have been transmitted prior to other SRS symbols that belong to the same TD-OCC block being dropped.
