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 and device for communicating in a wireless local area network are discussed. The method can include selecting, by a transmitting station, a transmission channel by performing a Clear Channel Assessment (CCA) and transmitting, by the transmitting station, a Physical layer Protocol Data Unit (PPDU) over the selected transmission channel to a receiving station, wherein the transmission channel includes a primary 20 MHz channel and a secondary 20 MHz channel if the secondary 20 MHz channel was idle, and wherein the transmission channel includes the primary 20 MHz channel, the secondary 20 MHz channel and a secondary 40 MHz channel if both the secondary 20 MHz channel and the secondary 40 MHz channel were idle.

Abstract: A method and device for receiving a data block in a wireless communication system, the method performed by a receiver. The method includes: receiving a physical layer protocol data unit (PPDU) from a transmitter over an operating channel, the PPDU including a signal field, a Very High Throughput-Signal-A (VHT-SIG-A) field, a Very High Throughput-Signal-B (VHT-SIG-B) field and a padded data block, generating a first data block by removing zero or more physical padding bits from the padded data block in a physical layer; and generating a second data block by removing zero or more Medium Access Control (MAC) padding bits from the first data block in a MAC layer.

Abstract: A method of transmitting signals by a transmitting end in a wireless communication system comprises sharing control information related to reference signal with a receiving end; generating one or more precoded reference signals considering a given rank; allocating the one or more precoded reference signals to have a specific pattern within a subframe, wherein the specific pattern is varied depending on the control information; and transmitting the subframe through multiple antennas to the receiving end.
