1. A method for use in an access point (AP), the method comprising:
receiving, from a station (STA), a first CF-End frame that includes a basic service set identifier (BSSID) field including an individual/group bit having a value of one (1) indicating that the BSSID field is a bandwidth signaling field indicating that the first CF-End frame carries bandwidth information in a physical (PHY) scrambling sequence of the first CF-End frame; and
transmitting, to the STA, in response to the first CF-End frame, a second CF-End frame using the same bandwidth information indicated by the first CF-End frame.
