Abstract
Systems and methods for collision handling between transmissions using a first Transmission Time Interval (TTI) and transmissions using a second TTI, such as a legacy TTI and a short TTI (sTTI), are provided. In some embodiments, the proposed solution helps the UE handle collisions between transmissions using legacy TTI in UL and overlapping transmissions using short TTI in UL. In some embodiments, this is accomplished by a wireless device adapted for uplink transmissions using a first TTI or a second TTI where the second TTI is shorter than the first TTI. The method includes altering at least one transmission of a first transmission using the first TTI and a second transmission using the second TTI based on a determination that a collision is to occur between the first transmission and the second transmission.
