摘要： A communication method performed by a target station in a Wireless Local Area Network (WLAN) system is provided. The communication method includes: receiving a relayed Traffic Indication Map (TIM) message from a relay station, wherein the TIM message comprises a relayed TIM field indicating whether or not there is buffered traffic intended to be transmitted from an Access Point (AP) to the target station; determining whether or not 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 in which communication between the relay station and the AP is permitted. The relayed TIM message is transmitted in a second period in which communication between the relay station and the target station is permitted.
