Abstract
A method for operating a transmit-receive point (TRP) includes generating a different spatial domain to time domain transform (STT) symbol for each antenna element in an antenna array, and transmitting the STT symbols using the antenna array to sweep a beam along a first plane in the time domain.
Claims26
A method for operating a transmit-receive point (TRP), the method comprising:
- generating, by the TRP, a different spatial domain to time domain transform (STT) symbol for each antenna element in an antenna array;
- and
- transmitting, by the TRP, the STT symbols using the antenna array to sweep a beam along a first plane in the time domain.
A method for operating a user equipment (UE), the method comprising:
- receiving, by the UE, signals associated with spatial domain to time domain transform (STI) symbols transmitted by a transmit-receive point (TRP);
- identifying, by the UE, signal peaks in the received signals;
- determining, by the UE, an angle of departure for the UE relative to the TRP in accordance with the signal peaks;
- and
- transmitting, by the UE, angle of departure information to the TRP.
