Claim of US Patent No. 10,973,036

1. An electronic equipment in a wireless communication system, comprising:processing circuitry configured to:
set, for a first user equipment served by the electronic equipment, information on a reference signal of a second user equipment being a candidate object for a Device-to-Device (D2D) communication of the first user equipment;
receive a measurement report from the first user equipment;
transmit switching information to notify the first and second user equipments to communicate with each other, when a communication object of the first user equipment is determined to be switched from a current communication object to the second user equipment based on the measurement report and information on a relative velocity between the first and second user equipment;
determine that the first user equipment is in a scenario in which a measured value of a D2D communication link quality between the first and second user equipments is lower than a threshold;
trigger a D2D communication link quality measurement between the first user equipment and a third user equipment among a plurality of user equipments;
determine to switch a D2D communication mode between the first and second user equipments to a D2D communication mode between the first and third user equipments based on the D2D communication link quality measurement between the first user equipment and the third user equipment;
determine whether the first user equipment is in a first scenario in which a system gain is improved when a D2D communication is performed between the first and second user equipments; and
initiate the setting of the configuration information when the first user equipment is in the first scenario,
wherein the communication mode is to be switched from a traditional cellular communication mode to the D2D communication mode when the first user equipment is in the first scenario and the measurement report indicates that a measured value of the quality of a D2D communication link between the first and second user equipments is greater than a first predetermined threshold.
