Abstract: A method for reporting the channel state information for a 3-dimensional beam forming in a wireless communications system. A method for transmitting the channel state information (CSI) in a wireless communications system includes the steps of: receiving a reference signal from a base station supporting a 2-dimensional antenna array; determining the CSI based on the reference signal; and transmitting the determined CSI to the base station. The CSI includes the CSI set for each of T beam candidates defined in one dimension of the 2-dimensional antenna array. The CSI set includes at least one of the rank index (RI) in the one dimension, the pre-coding matrix (PMI) index in the one dimension, the RI in the two dimensions, the PMI in the two dimensions, and the channel quality index (CQI). Here, the RI in the two dimensions is variable for each of the T beam candidates.

Abstract: A method of detecting a synchronization signal at a device-to-device (D2D) user equipment (UE) in a wireless communication system includes receiving a primary sidelink synchronization signal (PSSS), determining a normalized carrier frequency offset (CFO) from an initial CFO, determining hypothesis test levels from the normalized CFO, and performing correlation using the received PSSS, a first sequence, a second sequence, a first sequence shifted per hypothesis test level and a second sequence shifted per hypothesis test level. When the number of hypothesis test levels is greater than 1, the shifted first sequence and the shifted second sequence having a complex conjugate relation in a predetermined normalized CFO value are correlated via the same correlator.
