摘要: Provided are a signal transmitting method and apparatus, and a resource notification method and apparatus. The signal transmitting method includes: transmitting one or more random access signals. A tail end of the one or more random access signals is aligned with a t−Δt position of a signal transmission region in transmission resources of the one or more random access signals, t is a tail end time point of the signal transmission region and Δt is an advance. Alternatively, a transmitting start time point of the one or more random access signals is a result obtained by subtracting the length of the one or more random access signals and the advance from the tail end time point of the signal transmission region in the transmission resources.

摘要: Disclosed is a method for operating a communication node supporting a low power mode in a wireless LAN. A method for operating a station, which includes a PCR and a WURx, comprises the steps of: allowing the WURx, which operates in a wake-up state, to receive a wake-up packet from an access point; transitioning an operating state of the PCR from a sleep state to the wake-up state when the wake-up packet is received; allowing the PCR, which operates in the wake-up state, to receive a data frame from an access point; and allowing the PCR to transmit, to the access point, a response to the data frame.
