Abstract
A method for transmitting beamformed signals includes beamforming a synchronization signal in accordance with a first set of spatially separated transmission beams, thereby producing first beamformed synchronization signals, transmitting the first beamformed synchronization signals, determining if a first synchronization cycle is complete, and when the first synchronization cycle is not complete, rotating the first set of spatially separated transmission beams, and repeating the beamforming, the transmitting, and the determining until the first synchronization cycle is complete.
Claims13
A method for transmitting beamformed signals, the method comprising:
- beamforming, by a transmit-receive point (TRP), a synchronization signal in accordance with a first set of spatially separated transmission beams, thereby producing first beamformed synchronization signals;
- beamforming, by the TRP, a broadcast signal in accordance with the first set of spatially separated transmission beams, thereby producing first beamformed broadcast signals;
- transmitting, by the TRP, the first beamformed synchronization signals;
- transmitting, by the TRP, the first beamformed broadcast signals;
- determining, by the TRP, if a first cycle is complete;
- and
- based on the first cycle not being complete,
- rotating, by the TRP, the first set of spatially separated transmission beams, and
- repeating, by the TRP, the beamformings, the transmittings, and the determining until the first cycle is complete.
A transmit-receive point (TRP) adapted to transmit beamformed control signals, the TRP comprising:
- a non-transitory memory storage comprising instructions;
- and
- a processor in communication with the non-transitory memory storage, wherein the processor executes the instructions to:
- beamform a synchronization signal in accordance with a first set of spatially separated transmission beams, thereby producing first beamformed synchronization signals,
- beamform a broadcast signal in accordance with the first set of spatially separated transmission beams for synchronization, thereby producing first beamformed broadcast signals,
- transmit the first beamformed synchronization signals,
- transmit the first beamformed broadcast signals,
- determine if a first cycle is complete, and
- based on the first cycle being not complete,
- rotate the first set of spatially separated transmission beams, and
- repeat the beamformings, the transmittings, and the determining until the first cycle is complete.
