Abstract

Fremgangsmåte og apparat for sending, under trådløs kommunikasjon, av en signalramme som kan være en OFDM-superramme. Særskilt sendes et første pilotsymbol i signalrammen, der dette symbol tjener til kommunikasjon av grov tidsinformasjon overfor en mottaker. Et andre pilotsymbol sendes deretter for kommunikasjon av informasjon som gjelder nettidentifikasjon for et nett for et vidt område. Deretter sendes overordnet informasjon (OIS) som gjelder dette nett, og så sendes et tredje pilotsymbol for å kommunisere informasjon som gjelder nettidentifikasjonen for et nett for et lokalt område, til en mottaker. Ved sending av det tredje pilotsymbol som gjelder det lokale nett, etter sendingen av informasjonen OIS for det vide område muliggjøres at en mottaker kan hente ut tidsinformasjon og annen informasjon for nettet for vidt område og deretter fortløpende hente ut mer oppdatert slik informasjon fra nettet for lokalt område, hvorved prosesseringsressurser mer effektivt kan utnyttes.
