Method and apparatus for lightweight messaging during initial synchronization, discovery, and association in directional wireless systems

A method of wireless communication at a connection point (CP), comprising:

• transmitting a discovery signal via a directional beam to a user equipment (UE), wherein the discovery signal comprises a synchronization signal including first information related to the CP, the first information comprising beam sweep configuration information;
• receiving an association signal from the UE based on the beam sweep configuration information;
• and
• determining a resource grant for communicating with the UE based on the received association signal,
• wherein the beam sweep configuration information indicates a pattern for receiving the association signal in uplink by the CP, the pattern comprising a pattern according to a sequence of a plurality of beam directions.

A user equipment (UE), comprising:

• means for receiving a discovery signal transmitted from a connection point (CP) via a directional beam, wherein the discovery signal comprises a synchronization signal including first information related to the CP, the first information comprising beam sweep configuration information;
• means for transmitting an association signal to the CP based on the beam sweep configuration information;
• and
• means for monitoring for a resource grant from the CP based on the transmitted association signal,
• wherein the beam sweep configuration information indicates a pattern for receiving the association signal in uplink by the CP, the pattern comprising a pattern according to a sequence of a plurality of beam directions.
