TIMING ADVANCE AND PROCESSING CAPABILITIES IN A REDUCED LATENCY SYSTEM

A method and apparatus are described herein for handling reduced available processing time in systems configured to reduce latency such as systems using configurable transmission time intervals (TTIs) or short TTIs (sTTIs) and a processing capability (PC). A wireless transmit/receive unit (WTRU) may be configured to use a PC. The WTRU may receive a TTI configuration. The WTRU may determine the PC of the WTRU. The PC may be determined based on at least one of the TTI configuration and a processing criteria. The WTRU may then transmit a report of the determined PC. The report may be transmitted to and eNB. The PC may be a timeline, and the timeline may be reported as a number of time units, wherein a time unit is at least one of a symbol, a TTI, a time sample, and a set of time samples.
