Abstract
This disclosure describes systems, methods, and devices related to single-radio multi-channel medium access. A device may detect that a primary channel is occupied by a transmission of a first packet by a neighboring station device in an overlapping basic service set (OBSS). The device may detect that a secondary channel is idle. The device may select the secondary channel for packet transmission while the primary channel is occupied by the first packet. The device may cause to send a second packet to a first station device using the secondary channel.
Claims14
A device, the device comprising processing circuitry coupled to storage, the processing circuitry configured to:
- detect that a primary channel is occupied by a transmission of a first packet by a neighboring station device in an overlapping basic service set (OBSS);
- detect that a secondary channel is idle;
- select the secondary channel for packet transmission while the primary channel is occupied by the first packet;
- cause to send a second packet to a first station device using the secondary channel;
- and
- cause to send a null data packet basic service set color (NDP-BC) prior to sending the second packet, wherein the NDP-BC comprises an legacy short training field (L-STF), legacy long training field (L-LTF), and a coexisting signal (Coex-SIG) field, and wherein the L-STF, L-LTF and the Coex-SIG field are stored in the storage.
A non-transitory computer-readable medium storing computer-executable instructions which when executed by one or more processors of a device result in performing operations comprising:
- detecting that a primary channel is occupied by a transmission of a first packet by a neighboring station device in an overlapping basic service set (OBSS);
- detecting that a secondary channel is idle;
- selecting the secondary channel for packet transmission while the primary channel is occupied by the first packet;
- causing to send a second packet to a first station device using the secondary channel;
- and
- causing to send a null data packet basic service set color (NDP-BC) prior to sending the second packet, wherein the NDP-BC comprises an legacy short training field (L-STF), legacy long training field (L-LTF), and a coexisting signal (Coex-SIG) field.
A method comprising:
- detecting, by one or more processors of a device, that a primary channel is occupied by a transmission of a first packet by a neighboring station device in an overlapping basic service set (OBSS);
- detecting that a secondary channel is idle;
- selecting the secondary channel for packet transmission while the primary channel is occupied by the first packet;
- causing to send a second packet to a first station device using the secondary channel;
- and
- causing to send a null data packet basic service set color (NDP-BC) prior to sending the second packet, wherein the NDP-BC comprises an legacy short training field (L-STF), legacy long training field (L-LTF), and a coexisting signal (Coex-SIG) field.
