METHOD AND APPARATUS FOR LINK SCHEDULING IN DEVICE-TO-DEVICE (D2D) DIRECT COMMUNICATION NETWORK

摘要

The present invention relates to a method and an apparatus for link scheduling comprising the steps of: searching device-to-device (D2D) pairs capable of a D2D communication; obtaining channel coefficient information of each of the searched D2D pairs; sorting the searched D2D pairs in descending order using the channel coefficient; calculating a sum rate when a k-th D2D pair in the sorted order of the searched D2D pairs is added; comparing the sum rate with a sum rate when a k-1-th D2D pair is added; and selecting D2D pairs which can maximize the sum rate, considering the comparison result.
