Claim of US Patent No. 11,071,106


1. A method for wireless communication at a user equipment (UE), comprising:receiving, in a first downlink transmission time interval (TTI) of a scheduled transmission burst, over a shared radio frequency spectrum band, an indication of a downlink-uplink TTI configuration for the scheduled transmission burst, wherein the downlink-uplink TTI configuration indicates a first number of upcoming downlink TTIs to follow the first downlink TTI before a first downlink-uplink transition, the first number being relative to the first downlink TTI in which the UE receives the indication, and a second number of uplink TTIs to follow the first downlink-uplink transition in the scheduled transmission burst before a second downlink-uplink transition of the scheduled transmission burst; and
determining, based at least in part on the second downlink-uplink transition indicated by the downlink-uplink TTI configuration, a timing of a next downlink TTI in the scheduled transmission burst relative to the first downlink TTI in which the UE receives the indication.
