Abstract: A method is provided for calculating a distance to a counterpart user equipment (UE) using device-to-device (D2D) communication, which is calculated by a UE in a wireless communication system. The UE receives a synchronization signal from a cluster head and receives a first discovery signal from the counterpart UE, and calculates a first difference value between a time of receiving the first discovery signal and a time of receiving the synchronization signal. The UE further receives, from the counterpart UE, information on a second difference value and calculates a first sum value of the first difference value and the second difference value. The UE receives, from the cluster head, information on a second sum value. The UE calculates a distance between the UE and the counterpart UE based on a difference between the second sum value and the first sum value.

Abstract: A method is provided for a base station to transmit downlink control information to a relay through a Relay-Physical Downlink Control Channel (R-PDCCH). The base station transmits one or more candidate positions for the R-PDCCH. The base station further determines, based on the one or more candidate positions, a Virtual Resource Block (VRB) set for the R-PDCCH. Moreover, the base station transmits the downlink control information to the relay through the R-PDCCH. The one or more candidate positions are within the VRB set including at least one VRB, and a candidate position for the R-PDCCH of a higher aggregation level includes a combination of 2 adjacent candidate positions among candidate positions for the R-PDCCH of a lower aggregation level.

Abstract: A method and user equipment (UE) are provided for reporting channel state information (CSI). The UE supports massive multiple-input multiple-output (MIMO) technology in a wireless communication system. The UE receives, from an eNode B, M port CSI reference signals through a plurality of antenna ports composed of an L×M array, where L corresponds to a number of antenna ports in a horizontal direction and M corresponds to a number of antenna ports in a vertical direction. The UE selects a vertical antenna port by comparing energy of the M port CSI reference signals, and calculates a rank indicator (RI), precoding matrix indicator (PMI), and a channel quality indicator (CQI) of the selected vertical antenna port based on the M port CSI reference signals. The UE transmits the calculated RI, the calculated PMI and the calculated CQI to the eNode B.
