摘要： The present invention relates to a wireless communication system, and a method and apparatus for controlling channel access in a wireless LAN system. The method for controlling the channel access of a station (STA) of a wireless communication system according to the present invention comprises detecting a short frame transmitted by another STA; and deferring the channel access of the STA by a predetermined length of time. The short frame is a frame that triggers a service period during which the transceiving of a plurality of data frames of the other STA is allowed. The predetermined length of time can be set to the value corresponding to the length of time ranging from the start of the service period to the point in time at which the transceiving of a first data frame from among the plurality of data frames of the other STA is completed.

摘要： A method is provided for transmitting Acknowledgement/Negative Acknowledgement (ACK/NACK) information in a wireless communication system. A User Equipment (UE) configures a Physical Uplink Control Channel (PUCCH) format 3 for transmission of the ACK/NACK information. The UE transmits the ACK/NACK information for downlink transmission in a downlink subframe set including M downlink subframes in one uplink subframe, wherein M>1. A plurality of serving cells are configured for the UE and include one Primary Cell (PCell) and at least one Secondary Cell (SCell). The UE transmits the ACK/NACK information using a PUCCH format 1b when a first condition is met that comprises a condition in case where the ACK/NACK information corresponds to one Physical Downlink Shared Channel (PDSCH) without a corresponding Physical Downlink Control Channel (PDCCH) received only on the PCell in the downlink subframe set and the ACK/NACK information corresponds to an additional PDSCH indicated by detection of one corresponding PDCCH.
