CPC Class H04W

A computer-implemented method comprising: monitoring data traffic between an access point and an end station over a wireless link within a wireless communications network; deriving, based on the monitoring, one or more of the following quality factors associated with the wireless link: (i) a current retransmission rate quality factor over the wireless link, (ii) a current physical layer (PHY) rate quality factor of the wireless link, (iii) a current usage quality factor associated with a shared medium used by the wireless link, and (iv) a current interference quality factor associated with the shared medium; calculating, based on the derived one or more quality factors, a maximum predicted data rate associated with the wireless link; and determining an overall quality rating of the wireless link as equal to the ratio of (x) the calculated maximum predicted data rate, and (y) a maximum theoretical data rate associated with the wireless link.

This disclosure relates to method and system for generating spatial data maps corresponding to a centralized wireless network. The method includes receiving in real-time, network data from each of a plurality of data sources through one or more user space applications; computing in convenient time frame, derived information based on the network data and geographical location of data source; iteratively evaluating the derived information for each of plurality of data points in network data span with missing information through kriging interpolation technique to obtain continuous derived information; for each of data point with missing information in previous iterations, comparing the derived information of current iteration step with the derived information at previous iteration steps to obtain trust score; and generating spatial data map based on geographical location of each of the plurality of data sources and at least one of the continuous derived information and the trust score.

Apparatus and methods are provided for port selection codebook configuration. A user equipment (UE) may decode a channel state information (CSI) report configuration (CSI-ReportConfig) from a base station. The CSI-ReportConfig configuring a port selection codebook comprising a port selection matrix W1, a combinational coefficient matrix W2, and a frequency basis selection matrix Wf. Based on the CSI-ReportConfig, the determines, for the port selection matrix W1, up to L CSI reference signal (CSI-RS) ports out of P CSI-RS ports configured for measuring and reporting CSI. For the frequency basis selection matrix Wf, the UE determines up to Mv frequency basis out of N frequency basis. For the combinational coefficient matrix W2, the UE determines up to L*Mv entries per layer. The UE reports one or more of the port selection matrix W1, the combinational coefficient matrix W2, and the frequency basis selection matrix Wf to the base station.

Systems, methods, and devices enable spectrum management by identifying, classifying, and cataloging signals of interest based on radio frequency measurements. In an embodiment, signals and the parameters of the signals may be identified and indications of available frequencies may be presented to a user. In another embodiment, the protocols of signals may also be identified. In a further embodiment, the modulation of signals, data types carried by the signals, and estimated signal origins may be identified.
