Samsung patents Wi-Fi method to improve signal coordination between routers
This filing describes a way for multiple Wi-Fi routers to work together to send data more efficiently to a single device. It uses a mathematical technique called singular value decomposition to adjust how the second router sends its signal based on information gathered by the first router.
In the filing’s own words
A method, system and station are disclosed for coordinated beamforming with separated singular value decomposition (SVD). The method comprises performing, with a first access point (AP 1), an intra-basic service set (BSS) sounding of a first station (STA 1) to obtain an STA 1 -AP 1 intra-BSS left singular matrix U 11 and performing, with a second access point (AP 2), a cross-BSS sounding of the STA 1 to obtain a STA 1 -AP 2 cross-BSS channel matrix H 12. The method also comprises determining, with the STA 1, a new STA 1 -AP 2 cross-BSS channel matrix H 12 New based on a submatrix of the STA 1 -AP 1 intra-BSS left singular matrix U 11 and the STA 1 -AP 2 cross-BSS channel matrix H 12.
What exactly they claim (claim 1)
1. A method comprising: performing, with a first access point (AP 1), an intra-basic service set (BSS) sounding of a first station (STA 1) to obtain an STA 1 -AP 1 intra-BSS left singular matrix U 11; performing, with a second access point (AP 2), a cross-BSS sounding of the STA 1 to obtain a STA 1 -AP 2 cross-BSS channel matrix H 12; and determining, with the STA 1, a new STA 1 -AP 2 cross-BSS channel matrix H 12 New based on a submatrix of the STA 1 -AP 1 intra-BSS left singular matrix U 11 and the STA 1 -AP 2 cross-BSS channel matrix H 12.
