Abstract
Provided is a wireless communication terminal that communicates wirelessly. The terminal includes: a transceiver; and a processor. The processor is configured to receive a frame through the transceiver, determine whether the frame is classified into an Intra-Basic Service Set (BSS) frame or an Inter-BSS frame according to a BSS from which the frame is transmitted, and access a channel according to whether the frame is an Intra-BSS frame or an Inter-BSS frame.
Claims8
A wireless communication terminal that communicates wirelessly, the terminal comprising:
- a transceiver;
- and
- a processor,
- wherein a basic service set (BSS) of the wireless communication terminal corresponds to a multiple BSS identifier (BSSID) set,
- wherein the multiple BSSID set is a set of a BSSID of each of a plurality of BSSs classified into one group,
- wherein the processor is configured to:
- receive a frame through the transceiver,
- determine the frame as an Intra-BSS frame when a transmitter address (TA) or a receiver address (RA) signaled in a medium access control (MAC) header of the frame matches any one of a plurality of BSSIDs included in the multiple BSSID set, and
- enter a power save state when the frame is an Intra-BSS frame and a receiver address (RA) of the frame does not indicate the wireless communication terminal,
- wherein values of BSS colors corresponding to the plurality of BSSs are the same as each other, and
- wherein the BSS color is information identifying a BSS signaled in a physical layer signaling field of a PLCP Protocol Data Unit (PPDU) including the frame.
An operating method of a wireless communication terminal that communicates wirelessly, the method comprising:
- receiving a frame;
- determining the frame as an Intra-BSS frame when a transmitter address (TA) or a receiver address (RA) signaled in a medium access control (MAC) header of the frame matches any one of a plurality of BSSIDs included in a multiple basic service set identifier (BSSID) set to which a BSS of the wireless communication terminal corresponds, wherein the multiple BSSID set is a set of a BSSID of each of a plurality of BSSs classified into one group;
- and
- entering a power save state when the frame is an Intra-BSS frame and a receiver address (RA) of the frame does not indicate the wireless communication terminal,
- wherein values of BSS colors corresponding to the plurality of BSSs are the same as each other, and
- wherein the BSS color is information identifying a BSS signaled in a physical layer signaling field of a PLCP Protocol Data Unit (PPDU) including the frame.
