Lean deterministic beam/power feedback during 5G/6G initial access

A method for a base station of a wireless network to align a transmission beam toward a new user device during initial access, the method comprising:

• a) transmitting a synchronization signal block (“SSB”) message and a plurality of test signals;
• and
• b) receiving, from the new user device, a feedback message indicating which particular test signal was received with a highest signal quality;
• c) wherein the synchronization signal block message, other than the test signals, is transmitted isotropically, wherein each test signal of the plurality is transmitted in a different direction, wherein the test signals are placed in a formerly unallocated portion of the synchronization signal block message, separate from a primary synchronization signal (“PSS”) and separate from a secondary synchronization signal (“SSS”) and separate from a physical broadcast channel (“PBCH”) message comprising the synchronization signal block message, and wherein an indication of a latitude and a longitude of the base station is placed in the first symbol, not overlapping the primary synchronization signal and the test signals therein.
