Samsung patents method to compress wireless signal data for faster reporting
This filing describes a way for mobile devices to report network conditions to a cell tower using less data. The device breaks down the signal information into smaller parts, compresses the frequency details, and sends only the essential indicators back to the network.
In the filing’s own words
Apparatuses and methods for channel state information (CSI) reporting with frequency-domain compression. A method performed by a user equipment (UE) includes receiving information about a CSI report that indicates an antenna port group and determining, based on the information, a spatial domain (SD) basis vector b l for layer l=1,2..., v. The method further includes determining, based on the information, a coefficient value c l,n for layer l=1,2..., v and for subband (SB) n=0,..., N 3 −1, where v is a rank value and N 3 is a number of SBs and where the coefficient value is represented by a frequency domain (FD) compression component and a coefficient component and transmitting the CSI report including a precoding matrix indicator (PMI). The PMI includes a first indicator for the SD basis vector, a second indicator for the FD compression component, and a third indicator for the coefficient component.
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, the information indicating an antenna port group; and a processor operably coupled to the transceiver, the processor configured to: determine, based on the information, a spatial domain (SD) basis vector b l for layer l=1,2..., v; and determine, based on the information, a coefficient value c l,n for layer l=1,2,..., v and for subband (SB) n=0,..., N 3 −1, where v is a rank value and N 3 is a number of SBs, wherein the coefficient value is represented by a frequency domain (FD) compression component and a coefficient component, wherein the transceiver is further configured to transmit the CSI report including a precoding matrix indicator (PMI), and wherein the PMI includes a first indicator for the SD basis vector, a second indicator for the FD compression component, and a third indicator for the coefficient component.
