Zusammenfassung:Certain aspects of the present disclosure provide methods and apparatus for generating frames with portions utilizing different guard interval (GI) lengths. For example, an apparatus may include a processing system configured to generate a frame including a first portion with first blocks of symbols, including an end first block, surrounded by first guard interval (GI) sequences of a first GI length, and a second portion with second blocks of symbols, including a starting second block, surrounded by second GI sequences of a second GI length, and an interface for outputting the frame for transmission. A longer GI sequence of the first and second GI sequences may include a shorter of the first and second GI sequences, and the longer GI sequence of the first and second GI sequences may separate the end first block from the starting second block.
