Samsung patents Wi-Fi method for sharing airtime between routers

Patent drawing
Patent drawing from the official filing.

Samsung describes a method where Wi-Fi routers (access points) coordinate to share transmission time more efficiently. The system analyzes traffic needs and signal conditions to negotiate which router gets to send data next, aiming to reduce interference in dense networks.

Why it mattersThis could help improve Wi-Fi speeds and stability in crowded areas like offices or apartment buildings by preventing routers from stepping on each other's signals.

In the filing’s own words

A method performed by a device for allocating a shared portion of transmission opportunity (TXOP) within a coordinated time division multiple access (Co-TDMA) scheme is provided. The method includes identifying, by the device, a set of parameters associated with dynamic data traffic characteristics and channel access characteristics, generating, by the device, allocation rules based on these parameters, transmitting, by the device, to multiple neighboring access points (APs) participating in the Co-TDMA scheme, initiating, by the device, a negotiation of the allocation rules with at least one neighboring AP of the plurality of neighboring APs participating in the Co-TDMA scheme to determine candidate APs, and determining, by the device, one AP from the one or more candidate APs for allocating the TXOP, based on a predefined AP selection procedure associated with the dynamic traffic characteristic parameters and channel access characteristic parameters.

What exactly they claim (claim 1)

1. A method performed by a device for allocating shared portion of transmission opportunity (TXOP) within a coordinated time division multiple access (Co-TDMA) scheme, the method comprising: identifying, by the device, a set of parameters corresponding to each of dynamic data traffic characteristic and channel access characteristic; generating, by the device, allocation rules based on a combination of each of the set of parameters, the allocation rules comprising a predefined set of profiles indicative of functional relationships among the set of parameters; transmitting, by the device to a plurality of neighboring access points (APs) participating in a Co-TDMA scheme, the allocation rules through at least one communication frame; initiating, by the device, a negotiation of the allocation rules with at least one neighboring AP of the plurality of neighboring APs participating in the Co-TDMA scheme to determine one or more candidate APs from the plurality of neighboring APs for the Co-TDMA scheme, based on a response from each of the plurality of neighboring APs to the allocation rules; and determining, by the device, one AP from the one or more candidate APs for allocating the TXOP, based on a predefined AP selection procedure associated with the dynamic data traffic characteristic parameters and channel access characteristic parameters.
