Abstract: A method and apparatus for transmitting a signal from a base station to a first user equipment (UE) in a multiple-input multiple-output (MIMO) wireless communication system. Information on a movement speed of a second UE is acquired from the second UE. Channel information is determined based on the information on the movement speed. The channel information is previously measured by the first UE. A transmission and reception scheme is determined based on the determined channel information. At least one of the determined channel information or the determined transmission and reception scheme is transmitted to the second UE.

Abstract: Proposed is a control field including allocation information regarding a resource unit (RU) in a wireless local area network (WLAN) system supporting a plurality of RUs. A data field may be transmitted in unit of the RU. For a case where two 106-RUs are arranged and a plurality of user stations (STAs) are multiplexed to the respective 106-RUs, a SIG-B field may be used to perform signaling. More specifically, the number of STAs to be multiplexed may be indicated by using first and second identification bits in a user-common field of the SIG-B field.

Abstract: A method for transmitting channel status information (CSI) via uplink in a wireless communication system includes transmitting a first precoding matrix indicator (PMI) and a second PMI at a subframe. A subsampled codebook for each of a precoding codebook for Rank-1 and a precoding codebook for Rank-2 is determined based on at least the first PMI or the second PMI. In case of the Rank-1 or the Rank-2, a number of elements for the first PMI is 8.
