DEFINITIONS - 18

transmitted basic service set identifier (BSSID): The BSSID included in the MAC Header transmitter
address field of a Beacon frame when the multiple BSSID capability is supported.
tunneled direct-link setup (TDLS): A protocol that uses a specific Ethertype encapsulation to TDLS
frames through an access point (AP) to establish a TDLS direct link.
tunneled direct-link setup (TDLS) direct link: Direct link between two non-AP stations (STAs) that has
been established using the TDLS protocol.
tunneled direct-link setup (TDLS) initiator station (STA): A STA that transmits a TDLS Setup Request
frame or a TDLS Discovery Request frame.
tunneled direct-link setup (TDLS) peer power save mode (PSM): A power save mode that is based on
periodically scheduled service periods, which can be used between two stations (STAs) that have set up a
TDLS direct link.
tunneled direct-link setup (TDLS) peer power save mode (PSM) initiator: A station (STA) that
transmits a TDLS Peer PSM request frame.
tunneled direct-link setup (TDLS) peer power save mode (PSM) responder: A station (STA) that
transmits a TDLS Peer PSM response frame.
tunneled direct-link setup (TDLS) peer station (STA): A STA with a TDLS direct link.
tunneled direct-link setup (TDLS) peer unscheduled automatic power save delivery (U-APSD) [TDLS
peer U-APSD (TPU)]: A power save mode based on unscheduled service periods that can be used between
two stations (STAs) that have set up a TDLS direct link.
tunneled direct-link setup (TDLS) peer unscheduled automatic power save delivery (U-APSD) [TDLS
peer U-APSD (TPU)] buffer station (STA): A TDLS peer STA that buffers traffic for a TPU sleep STA.
tunneled direct-link setup (TDLS) peer unscheduled automatic power save delivery (U-APSD) [TDLS
peer U-APSD (TPU)] sleep station (STA): A TDLS STA that entered power save mode on a TDLS direct
link and that is using TPU for the delivery of buffered traffic.
tunneled direct-link setup (TDLS) power save mode (PSM): TDLS peer PSM or peer unscheduled
automatic power save delivery (U-APSD).
tunneled direct-link setup (TDLS) responder station (STA): A STA that receives or is the intended
recipient of a TDLS Setup Request frame or TDLS Discovery Request frame.
unauthorized disclosure: The process of making information available to unauthorized individuals,
entities, or processes.
unauthorized resource use: Use of a resource not consistent with the defined security policy.
unicast: See: individually addressed.
unicast address: See: individual address.
uniform spreading: A regulatory requirement for a channel selection mechanism that provides uniform
usage across a minimum set of channels in the regulatory domain.
