LOW LATENCY UNDER TIME DIVISION DUPLEX AND FLEXIBLE FREQUENCY DIVISION DUPLEX

摘要

Methods, systems, and devices for wireless communication are described. A user equipment (UE) may operate in a system that supports operation with transmission time intervals (TTIs) of different durations. The UE may monitor for a grant during a first TTI and may determine the communication direction of a second TTI based on a received grant. The UE may re-determine the communication direction of the second TTI based, for example, on an explicit indication. In some examples, the UE may adapt uplink scheduling timing based on the indicator. In some examples, a UE may communicate in one direction during a TTI of a first duration and may communicate in a different direction during a TTI of the second duration that is within the TTI of the first duration.
