摘要： A communication method performed by a target station in a WLAN system is provided. The method includes receiving a relayed TIM message from a relay station, the TIM message comprising a relayed TIM field indicating whether there is buffered traffic intended to be transmitted from an AP to the target station, determining whether there is the buffered traffic based on the relayed TIM field, receiving a data frame related to the buffered traffic, if the relayed TIM field indicates that there is the buffered traffic, and switching to a doze state, if the relayed TIM field indicates that there is no buffered traffic. The relayed TIM field is determined based on a TIM element transmitted from the AP to the relay station. The TIM element is transmitted in a first period, and the relayed TIM message is transmitted in a second period.
