1. A method of wireless communication of a user equipment (UE), comprising:

  • receiving, via a first network, first information from a base station of the first network;

    determining, based on the first information received via the first network, a position of resources for receiving a signal transmitted from a connection point of a second network via the second network, the connection point being an access point of the second network, the second network having a higher frequency than the first network;

    detecting the signal via at least one beam receiving direction based on the resources;

    determining a beam transmitting direction of the connection point and a beam receiving direction of the UE based on the signal;

    identifying a beam receiving direction of the connection point based on the beam transmitting direction of the connection point; and

    providing, from the UE to the connection point, second information based on the beam receiving direction of the connection point, the second information comprising at least two of;

    an intent to establish a millimeter-wave (mmW) link with the connection point,the beam receiving direction of the UE, orthe beam transmitting direction of the connection point.
