1. Knoten B zur Übertragung in einem drahtlosen Zeitduplex/Codemultiplex-
Vielfachzugriffs (TDD/CDMA)-Format, wobei der Knoten B aufweist:
- - einen Chipsequenzgenerator zum Erzeugen eines primären gemeinsamen physikalischen Steuerkanals (Primary Common Control Physical Channel/P-CCPCH), der einen primären Synchronisationscode enthält; und zum Erzeugen eines Abwärtsverbindungs-Pilot-Zeitschlitzes (Downlink Pilot Timeslot/DwPTS), der mindestens einen sekundären Synchronisationscode (SSC) enthält, wobei der PSC den Ort des SSC angibt;
- - einen Controller zum Platzieren des P-CCPCH und des DwPTS im richtigen Zeitschlitz und zum Erzeugen eines Datenstroms; und
- - einen Sender zum Senden des Datenstroms.
2. Zeitduplex (TDD)-Knoten B zum Übertragen in einem drahtlosen
Zeitteilungs-Duplex/Codemultiplex-Vielfachzugriffs (TDD/CDMA)-Format,
wobei der Knoten aufweist:
- - einen Generator zum Erzeugen mehrerer Sequenzen, die einen primären gemeinsamen physikalischen Steuerkanal (Primary Common Control Physical Channel/P-CCPCH) enthalten, der einen primären Synchronisationscode (PSC) hat, wobei der PSC den Ort eines folgenden sekundären Synchronisationscodes (SSC) angibt, der innerhalb eines Abwärtsverbindungs-Pilot-Zeitschlitzes (Downlink Pilot Timeslot/DwPTS) ist;
- - einen Controller zum Platzieren des P-CCPCH in einem ersten Zeitschlitz und des DwPTS in einem zweiten Zeitschlitz zum Erzeugen eines Datenstroms, wobei der zweite Zeitschlitz nach dem ersten Zeitschlitz gelegen ist; und
- - einen Sender zum Senden des Datenstroms.
