Abstract
Methods and systems for channel access in a BSS having two or more PCP/APs. A C-PCP/AP transmits at least a first management/extension frame, the management/extension frame including information for channel access by a STA. The C-PCP/AP receives, from the STA, at least a second management/extension frame. Based on information exchanged between the C-PCP/AP and the STA via at least the first and second management/extension frames, the STA is provided with channel access within the BSS by: the C-PCP/AP establishing a communication link for the C-PCP/AP to serve the STA; or the C-PCP/AP assigning a second PCP/AP in the BSS to serve the STA.
Claims23
A method, comprising:
- transmitting, by a coordination personal basic service set control point/access point (PCP/AP) in a single basic service set (BSS) having two or more serving personal BSS control PCPs/APs, at least a first management/extension frame, the management/extension frame including information for channel access by a station (STA) within the BSS;
- receiving, from the STA, at least a second management/extension frame;
- and
- based on information exchanged between the coordination PCP/AP (C-PCP/AP) and the STA via at least the first and second management/extension frames, providing the STA with channel access within the BSS by:
- establishing a communication link for the C-PCP/AP to serve the STA;
- or
- assigning, by the C-PCP/AP, a second PCP/AP in the BSS to serve the STA.
A coordination personal basic service set control point/access point (PCP/AP) comprising:
- a network interface configured for wireless communication with a station (STA) and at least a second PCP/AP within a single basic service set (BSS) having two or more serving PCPs/APs;
- and
- a processor coupled to the network interface and configured to execute instructions to cause the coordination PCP/AP (C-PCP/AP) to:
- transmit at least a first management/extension frame, the management/extension frame including information for channel access by the STA within the BSS;
- receive, from the STA, at least a second management/extension frame;
- and
- based on information exchanged between with the STA via at least the first and second management/extension frames, provide the STA with channel access within the BSS by:
- establishing a communication link to serve the STA;
- or
- assigning the second PCP/AP to serve the STA.
A method, comprising:
- in a single basic service set (BSS) having at least a coordination personal basic service set control point/access point (PCP/AP) and a second PCP/AP, transmitting, by the second PCP/AP, at least a first management/extension frame, the management/extension frame including information for channel access by a station (STA) within the BSS;
- receiving, from the STA, at least a second management/extension frame;
- and
- exchanging information with the coordination PCP/AP (C-PCP/AP), the exchanged information at least partially being based on information contained in the second management/extension frame from the STA.
A personal basic service set control point/access point (PCP/AP) comprising:
- a network interface configured for wireless communication with a station (STA) and at least a coordination PCP/AP (C-PCP/AP) within a single basic service set (BSS) having two or more serving PCPs/APs;
- and
- a processor coupled to the network interface and configured to execute instructions to cause the PCP/AP to:
- transmit at least a first management/extension frame, the management/extension frame including information for channel access by the STA within the BSS;
- receive, from the STA, at least a second management/extension frame;
- and
- exchange information with the C-PCP/AP, the exchanged information at least partially being based on information contained in the second management/extension frame from the STA.
