Abstract: For efficient communication in 5G and 6G, transmission beams are to be aligned with each user device as soon as possible during the initial access procedure. Prior-art procedures for downlink beam alignment consume large amounts of power and resources. Therefore, low-complexity formats and procedures are disclosed for a new user device to indicate its angular position relative to the base station upon entering the network. In one embodiment, the SSB message is broadcast isotropically, along with test signals which are transmitted in different directions. The user device indicates which test signal is best received, thereby indicating its angular direction. In a second embodiment, the test signals and feedback messages are appended to various entry messages after initial contact. Using either method, the base station and user device can then aim their beams toward the other, for enhanced signal quality thereafter.
