Samsung patents method for wireless devices to report signal quality
Samsung describes a way for phones and other devices to tell a cell tower how well they are receiving a signal. The device uses a pre-trained mathematical model, or 'basis,' to calculate this report based on specific signal parts called ports and subbands.
In the filing’s own words
Apparatuses and methods for channel state information (CSI) reporting. A method performed by a user equipment (UE) is provided. The method includes receiving a basis that is trained using data, and receiving information about a channel state information (CSI) report based on the basis. The information includes at least one parameter associated with the basis. The method further includes identifying the basis, determining the CSI report based on the basis and the information, and transmitting the CSI report. The basis, the data, and the CSI report are associated with P ports and N SB subbands (SBs).
What exactly they claim (claim 1)
1. A user equipment (UE), comprising: a transceiver configured to: receive a basis, wherein the basis is trained using data, and receive information about a channel state information (CSI) report based on the basis, the information including at least one parameter associated with the basis; and a processor operably coupled to the transceiver, the processor configured to: identify the basis, and determine the CSI report based on the basis and the information, wherein the transceiver is further configured to transmit the CSI report, and wherein the basis, the data, and the CSI report are associated with P ports and N SB subbands (SBs).
