    Abstract: A method of transmitting uplink signals is disclosed. The method includes transmitting, by a user equipment, periodic control information on a Physical Uplink Control Channel (PUCCH) at a predetermined period, dropping the periodic control information and multiplexing uplink signals except the periodic control information when the user equipment is operating in subframe bundling transmission mode where the uplink signals are transmitted in a plurality of consecutive subframes, and transmitting the multiplexed uplink signals on a Physical Uplink Shared Channel (PUSCH).

    Abstract: A method of transmitting a spatial stream for multi user (MU)-multiple input multiple output (MIMO) in a wireless local area network system and a transmitter for performing the method are provided. The method includes transmitting, to a receiver, a management frame including group information to assign or change a position of a plurality of spatial streams corresponding to each of a plurality of groups, and transmitting, to the receiver, a frame including at least one spatial stream, wherein the group information includes a plurality of group indicators and a plurality of spatial stream (SS) indicators, each of the plurality of group indicators indicating whether the receiver is a member of each of the plurality of groups, each of the plurality of SS indicators indicating a position of the plurality of spatial streams corresponding to each of the plurality of groups.

    Abstract: Provided are a method and an apparatus for transmitting a positioning reference signal (PRS) in a wireless communication system. A terminal obtains positioning subframe configuration information to determine at least one positioning subframe among a plurality of downlink subframes in a wireless frame, obtains downlink subframe configuration information to determine the type of each downlink subframe in the wireless frame, receives PRSs in at least one positioning subframe from a plurality of cells, and reports measured time differences between the PRSs received from the plurality of the cells. The type of each downlink subframe of the wireless frame is classified into a 1st type subframe and a 2nd type subframe, and the type of at least one positioning subframe is either the 1st type subframe or the 2nd type subframe. In addition, the PRSs are mapped into at least one positioning subframe on the basis of a single PRS pattern.

    Abstract: A method for transmitting a sounding reference signal in a MIMO wireless communication system and an apparatus therefor are disclosed. The method for transmitting sounding reference signals (SRSs) in a MIMO wireless communication system comprises receiving sounding reference signal parameters from a base station; receiving information of the number of sounding reference signals which will be transmitted at a transmission time instant from the base station; if a plurality of sounding reference signals are provided, generating the sounding reference signals corresponding to each of the plurality of antennas by using the sounding reference signal parameters; and transmitting the generated sounding reference signals to the base station through their corresponding antennas at a specific transmission instant.
