Methods, systems, and devices for wireless communications are described that provide for prioritization of uplink transmissions in the event that periodic configured uplink transmissions of a first priority have overlapping time or frequency resources with other uplink transmissions of a second priority, based on a collision resolution configuration. The collision resolution configuration may be preconfigured at a transmitting device such as a user equipment (UE) or indicated to the UE from a network node such as a base station. In some examples, the collision resolution configuration may indicate how the UE is to handle collisions between periodic high priority uplink transmissions (e.g., uplink control channel transmissions configured according to a semi-persistent scheduling (SPS) configuration) and lower priority uplink transmissions, which may be configured uplink transmissions or dynamically granted uplink transmissions.
