Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may identify a full-duplexing rule that indicates to refrain from using a transmission dropping rule for transmission direction conflicts that occur between uplink and downlink transmissions in a same symbol. The UE may receive a control message scheduling transmission of a message during a symbol, where a transmission direction conflict arises between a first transmission direction of the message and a second transmission direction of the symbol. For example, the UE may identify a transmission direction conflict between an uplink transmission direction of the message and a downlink transmission direction of the symbol. The UE may communicate the message during the symbol based on the full-duplexing rule. The described techniques may enable the UE to attain reduced latency and higher throughput based on reducing a number of transmissions dropped by the UE.
