    Abstract: A method for a channel sounding in a wireless local area network. A station receives a 20 MHz null data packet announcement (NDPA) frame and at least one duplicate 20 MHz NDPA frame. The at least one duplicate 20 MHz NDPA frame is a duplicate of the 20 MHz NDPA frame. The station also receives a null data packet (NDP) following the 20 MHz NDPA frame and the at least one duplicate 20 MHz NDPA frame. The bandwidth over which the 20 MHz NDPA frame and the at least one duplicate 20 MHz NDPA frame are transmitted is the same as a bandwidth over which the NDP is transmitted. The station transmits a report frame for the channel sounding. The 20 MHz NDPA frame and the at least one duplicate 20 MHz NDPA frame comprise bandwidth information indicating the bandwidth over which the frames are transmitted.

    Abstract: A method for transmitting channel quality information for a downlink channel. The method according to one embodiment includes receiving, by a User Equipment (UE), configuration information on periodic channel state information (CSI) reporting by higher layer signaling; and determining, by the UE, a channel quality information index at least based on a UE-specific reference signal overhead. The UE-specific reference signal overhead is determined according to a rank value. The method according to the one embodiment further includes transmitting the determined channel quality information index to a base station. The channel quality information index is determined further based on an assumption of no resource element allocated for a Channel Status Information-Reference Signal (CSI-RS).

    Abstract: A base station apparatus for transmitting a reference signal in a wireless communication system is provided in which a processor generates the same sequence for resource elements (REs) allocated to each layer for reference signal transmission and spreads or covers Walsh codes for a user equipment—specific reference signal sequence such that sequences generated for the resource elements can be orthogonal to each other on a time axis. The Walsh code spreading or covering by the processor is applied on a frequency axis based on a plurality of resource blocks (RBs) or based on a pair of resource blocks such that mutually different sequences having mutually different sequence values can be mapped between resource blocks or between pairs of resource blocks. A transmission module transmits the reference signal, to which the generated reference signal sequence is applied to user equipment via each layer.
