The apparatus may identify a potential collision between a scheduled legacy transmission time interval (TTI) communication and a scheduled shortened TTI (sTTI) communication, the legacy TTI communication having a legacy TTI duration that is longer than an sTTI duration associated with the sTTI communication. The apparatus may determine whether the legacy TTI communication is within a threshold time of being transmitted. The apparatus may transmit at least one of the sTTI communication, the legacy TTI communication, or any combination thereof, based at least in part on the determination.
