Abstract: A method for transmitting control information using PUCCH format 3 in a radio communication system includes detecting one or more Physical Downlink Control Channels (PDCCHs), receiving one or more Physical Downlink Shared Channel (PDSCH) signals corresponding to the one or more PDCCHs, and determining a PUCCH resource value nPUCCH(3,p) corresponding to a value of a transmit power control (TPC) field of a PDCCH for a PDSCH signal on a secondary cell (SCell) among a plurality of PUCCH resource values configured by a higher layer for the PUCCH format 3. If a single antenna port transmission mode is configured, the PUCCH resource value nPUCCH(3,p) indicated by the TPC field is mapped to one PUCCH resource for a single antenna port, and, if a multi-antenna port transmission mode is configured, the PUCCH resource value nPUCCH(3,p) indicated by the TPC field is mapped to a plurality of PUCCH resources for multiple antenna ports.

Abstract: Proposed are a method and an apparatus for transmitting a signal by performing MIMO beamforming in a wireless LAN system. Specifically, a first STA performs MIMO beamforming during a second STA and TDD-based SP. The first STA transmits a signal to the second STA on the basis of a result of the MIMO beamforming. The SP includes a plurality of TDD slots. The MIMO beamforming includes a first sub-step and a second sub-step. In the first sub-step, after receiving a first MIMO beamforming setup frame from the second STA, the first STA transmits a second MIMO beamforming setup frame in the first allocated TDD slot among the TDD slots allocated to the first STA. In the second sub-step, after receiving a first MIMO beamforming feedback frame from the second STA, the first STA transmits a second MIMO beamforming feedback frame in a first allocated TDD slot among the TDD slots allocated to the first STA.

Abstract: Provided are a method for beamforming training and an apparatus using the same. An STA receives a beacon frame from an AP during a BTI. The STA transmits SSW frames during an A-BFT. The beacon frame comprises an A-BFT length indicating the number of a plurality of SSW slots included in the A-BFT, a FSS field indicating the number of the SSW frames allowed in one SSW slot among the plurality of SSW slots, and information about the type of the SSW frames used in one SSW slot. The information about the type of the SSW frames indicates that the SSW frames are determined to be one from among first type SSW frames and second type SSW frames. The second type SSW frames have a smaller size than that of the first type SSW frames. If the SSW frames are determined to be the second type SSW frames, the FSS field indicates the number of the second type SSW frames that can be transmitted in one SSW slot.

Abstract: A method and apparatus for transmitting frames having a signaling field (SIG) for a second type of station (STA) in a wireless communication system are provided. For this, STA prepares a frame having a first part for a first type of STA and a second part for the second type of STA. Here, the second part includes a first signaling field (HE-SIG A) for common control information and a second signaling field (HE-SIG B) for signaling information comprising user specific control information. Regarding the second signaling field, independent signaling information for the second signaling field (HE-SIG B) is to be transmitted for each 20 MHz bandwidth within a first 40 MHz bandwidth. And the signaling information of the first 40 MHz bandwidth is duplicated in a second 40 MHz bandwidth, when the frame is to be transmitted in a bandwidth equals to or greater than 80 MHz. STA transmits this prepared frame to one or more STAs.
