In some aspects, a user equipment (UE) may identify a resource block set that includes a data region and a control region, wherein the resource block set spans a portion of a system bandwidth in a shortened transmission time interval (sTTI), wherein the sTTI includes three symbols, wherein the control region occupies the three symbols and includes control information for the UE for the sTTI, and wherein the control region and the data region are frequency division multiplexed. The UE may obtain content in the sTTI based at least in part on the control information. Nu- merous other aspects are provided. 1005 s'IT1 n 1010 1015 1020 tiro • W O 20 18/ 20 4065 Al 1040 Time 1035 ' 177 DL Grant for UE A Reallocated sPI)SCH for BF A 1045 UL Gnml for UH B FIG. 10 1000
