METHODS AND APPARATUSES OF DEVICE TO DEVICE COMMUNICATION USING CHANNEL ESTIMATION OF A RECEIVING USER EQUIPMENT

摘要

The present invention provides a method of obtaining channel information, in which a receiving terminal overhears a signal in a physical uplink shared channel (PUSCH) used by surrounding terminals so that an average receiving power is measured in a resource block (RB) in slot units, According to a method and an apparatus for performing communication between terminals, an amount of reference signal related information and a calculation complexity, which are required for detecting the reference, are not increased because the reference signal is not used when measuring the channel information.
