1. A method performed by a first user equipment to establish a peer-to-peer millimeter wave link with a second user equipment, the method comprising:
receiving, by the first user equipment and from a base station of a wireless network, an indication of a grant of air interface resources for the first user equipment to communicate on the peer-to-peer millimeter wave link with the second user equipment;
receiving, by the first user equipment and from the base station, instructions to perform a beam-sweeping procedure to select a beam for establishing and to communicate on the peer-to-peer millimeter wave link with the second user equipment, the instructions including a beam correspondence procedure with a first correspondence procedure for transmission from the first user equipment to the second user equipment and a second correspondence procedure for reception by the first user equipment from the second user equipment;
executing the beam-sweeping procedure to select the beam for establishing the peer-to-peer millimeter wave link with the second user equipment; and
communicating data with the second user equipment using the first correspondence procedure or the second correspondence procedure and the beam selected in response to executing the beam-sweeping procedure.
