Abstract
A base station for a mobile telecommunications system has circuitry configured to communicate with at least one user equipment, wherein the circuitry is further configured to set a first subcarrier spacing for transmission of at least one synchronization signal; and set a second subcarrier spacing for transmission on a physical broadcast channel, wherein the first subcarrier spacing differs from the second subcarrier spacing.
Claims15
A base station for a mobile telecommunications system, the base station comprising:
- circuitry configured to:
- communicate with at least one user equipment;
- and
- transmit symbols on a physical broadcast channel (PBCH) with a subcarrier spacing, wherein
- modulation symbols are repeated in consecutive resource elements in a frequency domain,
- each burst of the PBCH with the subcarrier spacing includes a reference symbol repeated in the consecutive resource elements,
- the subcarrier spacing of the PBCH differs from a subcarrier spacing of a primary synchronization signal,
- the primary synchronization signal includes a synchronization sequence,
- a sign of one part of the synchronization sequence corresponds to the subcarrier spacing of the primary synchronization signal, and
- a sign of another part of the synchronization sequence corresponds to the subcarrier spacing of the PBCH.
A user equipment for a mobile telecommunications system, the user equipment comprising:
- circuitry configured to:
- communicate with at least one base station;
- and
- receive symbols on a physical broadcast channel (PBCH) with a subcarrier spacing, wherein
- modulation symbols are repeated in consecutive resource elements in a frequency domain,
- each burst of the PBCH with the subcarrier spacing includes a reference symbol repeated in the consecutive resource elements,
- the subcarrier spacing of the PBCH differs from a subcarrier spacing of a primary synchronization signal,
- the primary synchronization signal includes a synchronization sequence,
- a sign of one part of the synchronization sequence corresponds to the subcarrier spacing of the primary synchronization signal, and
- a sign of another part of the synchronization sequence corresponds to the subcarrier spacing of the PBCH.
A base station for a mobile telecommunications system, the base station comprising:
- circuitry configured to:
- communicate with at least one user equipment;
- and
- transmit symbols, on a physical broadcast channel (PBCH), by applying a phase ramp, wherein
- each burst of the PBCH includes a reference symbol that is repeated in consecutive resource elements,
- a subcarrier spacing of the PBCH differs from a subcarrier spacing of a primary synchronization signal,
- the primary synchronization signal includes a synchronization sequence,
- a sign of one part of the synchronization sequence corresponds to the subcarrier spacing of the primary synchronization signal, and
- a sign of another part of the synchronization sequence corresponds to the subcarrier spacing of the PBCH.
