PHYSICAL DOWNLINK CONTROL CHANNEL, PDCCH, SEARCH SPACE DESIGN FOR FIFTH GENERATION, 5G, AND LATENCY REDUCTION

摘要

Techniques for xPDCCH (5G (Fifth Generation) Physical Downlink Control Channel) design are discussed. In various aspects, xPDCCH can be transmitted via one or more OFDM (Orthogonal Frequency Division Multiplexing) symbols, with each OFDM symbol comprising a xPDCCH search space. Each xPDCCH search space can have one or two distinct xPDCCH sets, with each xPDCCH set having a xCCE (5G Control Channel Element) starting position that can be based on one of several predetermined rules, and can depend on one or more factors.
