Abstract:
The present document relates to a method for transmitting and receiving signals by controlling interference on other wireless devices based on actual transmitted power or received power information in a wireless communication system, and an apparatus therefor. To this end, STA 1 receives from STA 2 a frame comprising power information about actual transmitted power or actual received power of STA 2. Through the frame, STA 1 determines transmitted power by correcting the existing transmitted power of STA 1 by using the power information of STA 2 and, when the determined transmitted power of STA 1 is less than or equal to a reference value, transmits signals through the frame.

In a wireless communication system, when a terminal receives control information from a downlink subframe, which is divided into a Physical Downlink Control Channel (PDCCH) region and a Physical Downlink Shared Channel (PDSCH) region, in a wireless communication system, the receiving of the control information includes: receiving, from a base station, first CFI information indicating the number of Orthogonal Frequency Division Multiplexing (OFDM) symbols available for Physical Downlink Control Channel (PDCCH) transmission; receiving, from the base station, second CFI information indicating start OFDM symbol information available for Physical Downlink Shared Channel (PDSCH) transmission corresponding to an enhanced Physical Downlink Control Channel (E-PDCCH); and receiving the PDSCH from the base station on the basis of the first CFI information or the second CFI information. The PDCCH is placed in the PDCCH region of the downlink subframe, and the E-PDCCH is placed in the PDSCH region of the downlink subframe.
Abstract:
Proposed are a method and apparatus for receiving a PPDU on which BCC interleaving has been performed in a Multi-RU in a wireless LAN system. Specifically, a reception STA receives, from a transmission STA, a PPDU comprising a data field and decodes the data field. The data field is received via a Multi-RU which is an aggregate of a first RU and a second RU. The data field is generated on the basis of a coded bit string included in a BCC interleaver block. The coded bit string is obtained by interleaving a data bit string on the basis of first and second parameters. The data bit string is interleaved as the data bit string is entered into the BCC interleaver block in rows on the basis of the first parameter and is read out in columns of the BCC interleaver block on the basis of the second parameter.
