Samsung patents method to compress wireless channel data

Samsung has filed a patent for a way to report channel state information (CSI) in wireless networks using compression and transformation matrices. The method allows a device to send a smaller amount of data by converting information from one set of ports or frequency bands to another.

Why it mattersThis is a technical improvement to how devices manage network data, potentially making wireless connections more efficient by reducing the amount of information sent.

In the filing’s own words

Apparatuses and methods for training-based channel state information (CSI) in wireless communication systems. A method performed by a user equipment (UE) includes receiving information about a CSI report based on a compression, matrix determining the CSI report based on the compression matrix and a transformation matrix, and transmitting the CSI report. The compression matrix is associated with P ports or N subbands (SBs). The CSI report is associated with Q ports or R SBs, where P≠Q, and N≠R. The transformation matrix transforms Q ports to P ports or R SBs to N SBs.

What exactly they claim (claim 1)

1. A user equipment (UE), comprising: a transceiver configured to receive information about a channel state information (CSI) report based on a compression matrix, wherein: the compression matrix is associated with P ports or N subbands (SBs), and the CSI report is associated with Q ports or R SBs, where P≠Q, and N≠R; and a processor operably coupled to the transceiver, the processor configured to determine the CSI report based on the compression matrix and a transformation matrix, wherein the transformation matrix transforms (i) Q ports to P ports or (ii) R SBs to N SBs, and wherein the transceiver is further configured to transmit the CSI report.
