Abstract: The present disclosure provides a method for pilot allocation using the Hungarian algorithm in a cell-free massive MIMO system. The method includes obtaining a first matrix by computing a large-scale channel gain between each of a plurality of UEs and each of a plurality of APs included in the cell-free massive MIMO system; assigning each of the plurality of UEs to a first group or a second group by using the first matrix; allocating a pilot to each UE in the second group; obtaining a second matrix by computing the reusability of pilots between each UE in the first group and each UE in the second group; and allocating a pilot to each UE in the first group by applying the Hungarian algorithm to the second matrix.

Abstract: Disclosed is a proximity measurement method and apparatus for device-to-device (D2D) communication in a mobile communication system. The proximity measurement method may include determining whether a cell identification (ID) is included in a packet received from a gateway, verifying whether the cell ID matches a pre-stored cell ID when the cell ID is included, extracting, from the packet, Internet Protocol addresses of mobile terminals transmitting and receiving the packet when the cell ID matches the pre-stored cell ID, searching for IP addresses matched to the extracted IP addresses based on a proximity list including IP addresses of mobile terminals performing D2D communication, and registering, when the extracted IP addresses are absent in the proximity list, the extracted IP addresses in the proximity list and measuring proximity between the mobile terminals.
