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.
Claims16
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 first frame through the transceiver,
- determine the first frame as an Intra-BSS frame when a medium access control (MAC) address signaled in a MAC header of the first frame matches any one of a plurality of BSSIDs included in the multiple BSSID set,
- sense a signal strength while receiving the first frame,
- determine, according to comparing the signal strength with a threshold, whether to transmit a second frame while the first frame is being transmitted, wherein a value of the threshold is determined based on the determining the first frame as the Intra-BSS frame, and
- transmit the second frame based on the determining whether to transmit the second frame.
A method of operating a wireless communication terminal that communicates wirelessly, the method comprising:
- receiving a first frame;
- determining the first frame as an Intra-BSS frame when a medium access control (MAC) address signaled in a MAC header of the first 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;
- sensing a signal strength while receiving the first frame;
- determining, according to comparing the signal strength with a threshold, whether to transmit a second frame while the first frame is being transmitted, wherein a value of the threshold is determined based on determining the first frame as the Intra-BSS frame;
- and
- performing the transmission based on the determining whether to transmit the second frame.
