  • Patent number: 10278190
    Abstract: Disclosed is a network node and a method performed by a network node in a wireless communication network for determining signal to noise ratio of a signal received at a receiver from a first mobile station, which signal may include both noise and interference. The method comprises obtaining a plurality of measured noise and interference power values, IN values, of signals received at the receiver in one or more frequency sub-bands, determining IN for a lowest X percentile of the measured IN values, and applying the determined IN for the lowest X percentile as a measure of the noise. The method further comprises obtaining a measured signal strength value for a signal received at the receiver from the first mobile station, and determining SNR for the signal from the first mobile station by applying the determined noise measure.

  • Patent number: 10212258
    Abstract: A data communication system compresses packet headers. A transmitter executes state machines to process a data packet and determine if a transmitter state machine is transferring Interdependent Machine Output (IMO) data. The transmitter generates an IMO vector that indicates if any IMO data is in the data packet. If IMO is present, then the transmitter augments the IMO vector to indicate the individual transmitter state machines that transferred the IMO data. The transmitter transfers the data packet with the IMO vector to a receiver. The receiver processes the IMO vector to determine if any IMO data is transferred in the data packet. If IMO data is transferred, then the receiver processes the augmented IMO vector to transfer the IMO data to individual receiver state machine that correspond to the transmitter state machines that transferred the IMO data.
