  • Patent number: 11917667
    Abstract: Disclosed are example embodiments of systems and methods for an interference imbalance manager (IIM). The method includes an outer loop that goes over the K subcarrier sets ki and an inner loop that goes over the M dominant intra-frequency cells that IC are performed on, for each subcarrier set ki the noise plus interference power estimate of that set is initialized by N by setting: N(ki)=N. The method includes, for each subcarrier set ki the IIM determine when the pilots of each cell m collide with that subcarrier set. When there is no collision, the interference plus noise of that set N(ki) is not adjusted. When there is a collision the interference plus noise of that set N(ki) is adjusted by removing the power contribution Em of that cell by applying the correction: N(ki)=N(ki)?Em. The method includes looping over all considered cells M and when all adjustments are complete to N(ki) for subcarrier set ki the program provides the adjusted N(ki) output and exits the m loop.

  • Patent number: 11463223
    Abstract: A method for receiving repeated transmission of portions of data from a transmitter, the method comprising at a processor of a receiver, deriving a metric indicative of a desired PER of the received repeated portions of data, based on the desired PER of the received repeated portions of data at the receiver, deriving an optimal number of repetitions of each portion of the data to be received for successful decoding, wherein when the optimal number of repetitions have been received, decoding is to be activated; and further wherein the optimal number of repetitions is derived such that power consumption to successfully decode the data is minimized at the receiver.
