摘要： A method for transmitting information data by using a Reed-Muller coding scheme in a wireless communication system is disclosed. The method includes configuring a number of resource elements for transmitting the information data; dividing the information data to first information data and second information data if a bit size O of the information data is equal to or larger than a predetermined number; applying RM coding on each of the first information data and the second information data; concatenating the coded first information data and the coded second information data, and transmitting the concatenated data by using the predetermined number of resource elements, wherein a minimum value Q′min for the number of resource elements is defined by a sum of a minimum value Q′min_1 for the number of resource elements corresponding to the first information data and a minimum value Q′min_2 for the number of resource elements corresponding to the second information data.

摘要： A method of receiving a channel state information (CSI) report by a base station in a wireless communication system; the BS station (BS) therefore; a method of transmitting a CSI report by a user equipment (UE) in a wireless communication system; and the UE therefore are discussed. The method of receiving a CSI report according to one embodiment includes transmitting, via radio resource control (RRC) signaling, information for configuring at least one secondary cell (SCell) in addition to a primary cell (PCell) and a plurality of periodic CSI feedback configurations for a plurality of serving cells; and receiving, via a subframe of the PCell, a CSI report for only one of the plurality of serving cells. When CSI reports of two or more serving cells collide, CSI reports are dropped. When CSI reports of different serving cells having a same priority collide, CSI reports are dropped.
