Summary:Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, from a base station, control signaling indicating a set of resources for transmitting a set of uplink shared channel transmissions and a set of demodulation reference signals (DMRSs) having phase coherence across a set of transmission time intervals (TTIs). The UE may receive, from the base station, a control message indicating a cancellation of a first resource of the set of resources. The UE may determine one or more phase-continuity conditions for the set of resources based on receiving the control message indicating the cancellation of the first resource. The UE may transmit, in remaining resources of the set of resources, at least a subset of the set of uplink shared channel transmissions and at least a subset of the set of DMRSs in accordance with the one or more phase-continuity conditions.
