The method includes: selecting a ZC sequence group according to a cell type and a first cyclic shift parameter Ncs, and setting N detection windows for each ZC sequence in the ZC sequence group, where N≧5; sending the cell type, a second Ncs, and the ZC sequence group to a UE; receiving a random access signal sent by the UE, and obtaining the random access sequence from the random access signal; performing correlation processing on the random access sequence with each ZC sequence in the ZC sequence group, detecting a valid peak value in the N detection windows of each ZC sequence, and determining an estimated value of an RTD according to the valid peak value, so that a UE in a very-high-speed scenario can normally access a network, thereby improving network access performance."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method, apparatus and system for processing very-high-speed random access","description":"The present invention discloses a method, an apparatus and a system for processing very-high-speed random access.
