METHOD AND SYSTEM FOR PROCESSING REFERENCE SIGNALS IN OFDM SYSTEMS USING TRANSMISSION TIME INTERVAL GROUPINGS

摘要

A method and system processes reference signals (115) for an uplink channel (103) between a transmitter, such as user equipment, and a receiver such as a base station, in a wireless commuication network. A sequence of symbols to be transmitted is converted to a sequence of sub frames. The sequence of sub frames is grouped into groups of sub frames. Each sub frames includes at least two time-adjacent sub frames, and reference signals are inserted in a subset of the sub frames.
