Abstract

Piloter (pilotsignaler) sendes ved behov via en returlink og brukes til kanalestimering via en foroverlink. En basestasjon velger minst en terminal for behovspilotsending via returlinken, og hver valgt terminal gjelder som kandidat for å motta datatransmisjon via foroverlinken. Basestasjonen tildeler hver valgt terminal en tidsfrekvensallokering som kan gjelde en bredbånds-, en smalbåndspilot eller en annen type. Basestasjonen mottar og behandler slike behovspilotsendinger fra hver valgt terminal og utleder et kanalestimat for terminalen, basert på den mottatte pilotsending. Videre kan basestasjonen sette opp en senderplan for terminaler for deres datatransmisjon via foroverlinken, basert på kanalestimatene for alle valgt terminaler, og stasjonen kan også behandle data (så som utføre stråleforming eller egenstyring) for sending til hver terminal som er tillagt en plan, basert på kanalestimat for kanalen.
