Abstract
A method for synchronizing a user equipment (UE) is provided. The method includes determining a first beam identifier associated with a transmission beam conveying a first received beamformed synchronization signal, determining if a first synchronization cycle is complete, and based on the first synchronization cycle not being complete, repeating the determining the first beam identifier, and the determining if the first synchronization cycle is not complete until the first synchronization cycle is complete.
Claims21
A method for synchronizing a user equipment (UE), the method comprising:
- receiving, by the UE from a first transmit-receive point (TRP), a first beamformed synchronization signal in accordance with a first set of spatially-separated transmission beams;
- receiving, by the UE from the first TRP, a first beamformed broadcast signal in accordance with the first set of spatially-separated transmission beams;
- determining, by the UE, a first beam identifier associated with a first transmission beam conveying the first beamformed synchronization signal;
- determining, by the UE, if a first cycle is complete;
- and
- based on the first cycle not being complete,
- repeating, by the UE, the receivings, the determining the first beam identifier, and the determining if the first cycle is not complete, for a rotated first set of spatially-separated transmission beams, until the first cycle is complete.
A user equipment (UE) comprising:
- a non-transitory memory storage comprising instructions;
- and
- one or more processors in communication with the non-transitory memory storage, wherein the one or more processors executes the instructions to:
- receive, from a transmit-receive point (TRP), a first beamformed synchronization signal in accordance with a first set of spatially-separated transmission beams,
- receive, from the TRP, a first beamformed broadcast signal in accordance with the first set of spatially-separated transmission beams,
- determine a first beam identifier associated with a transmission beam conveying the first beamformed synchronization signal,
- determine if a first cycle is complete, and
- based on the first cycle not being complete,
- repeat the receivings, the determining the first beam identifier, and
- determining if the first cycle is not complete, for a rotated first set of spatially-separated transmission beams, until the first cycle is complete.
