Abstract

Methods and apparatus for generating a scheduling grant for a wireless device of a communication system are provided. The communication system supports variable TTI lengths to be transmitted in one TTI. It is presented how to determine a TTI length for a scheduled TTI, where the TTI length is determined in number of symbols. It is further presented how to determine at least one reference signal parameter for the scheduled TTI, where the at least one reference symbol parameter is selected from a reference symbol position and a reference symbol cyclic shift. Finally, encoding the TTI length and the at least one reference symbol parameter into a TTI index is presented.
