Techniques are described for handling collisions between uplink transmissions and downlink transmissions over a wireless spectrum. Some of the techniques allow a UE to perform a collision management procedure after identifying a transmission collision (e.g., a collision between a downlink transmission with repetition and an uplink transmission, or a collision between a downlink transmission with repetition and a guard frame for an uplink transmission). The collision management procedure allows the UE to refrain from transmitting at least part of an uplink transmission, refrain from decoding at least part of a downlink transmission, or a combination thereof. Other techniques allow a base station to mitigate transmission collisions by scheduling downlink transmissions based on received, inferred, or determined parameters of uplink transmissions.
