Abstract: A method and apparatus for allowing a UE to transmit uplink signals using a MIMO scheme are disclosed. In order to maintain good Peak power to Average Power Ratio (PAPR) or Cubic Metric (CM) properties when the UE transmits uplink signals using the MIMO scheme, the UE uses a precoding scheme based on a precoding matrix established in a manner that one layer is transmitted to each antenna in specific rank transmission.

Abstract: A method is provided for transmitting data in a wireless local area network. A transmitter generates an encoded data unit by performing a channel coding to transmission data to be included in a data field of a physical layer protocol data unit (PPDU). The transmitter generates at least one spatial block by re-arranging the encoded data unit, and divides each spatial block of at least one spatial block into two frequency segments. A bandwidth of each frequency segment is half of a bandwidth of the each spatial block. The transmitter interleaves the two frequency segments to generate a first interleaved segment and a second interleaved segment, respectively, and generates first and second mapped sequences by respectively mapping the first and second interleaved segments into a signal constellation. The transmitter performs an Inverse Discrete Fourier Transform (IDFT) on the first and second mapped sequences to generate and transmit a transmission signal.

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.
