Abstract: Devices and methods for determining a wideband Channel Quality Indicator (wbCQI) and a plurality of sub-band Channel Quality Indicators (CQIs) for reporting to a network, including deriving a first metric for a wideband and each of a plurality of sub-bands from a received signal; converting the wideband first metric and the plurality of sub-band first metrics to a wideband CQI and a plurality of sub-band CQIs; determining a skewness of the plurality of sub-band CQIs to the wideband CQI by comparing each of the plurality of sub-band CQIs to the wideband CQI; modifying the wideband CQI when a negative skewness is determined and recomputing the plurality of sub-band CQIs based on the modified wideband CQI; and providing the modified wideband CQI and the plurality of recomputed sub-band CQIs to the network.

Abstract: This disclosure relates to a channel state information, CSI, acquisition circuitry, configured to: determine at least one channel covariance matrix estimate and interference-and-noise covariance matrix estimate based on at least one channel state information reference signal, CSI-RS, resource; select a restricted number of rank indicator, RI, hypotheses from a set of RI hypotheses for running a joint rank indicator-precoding matrix indicator, RI-PMI, search on the CSI-RS based channel covariance matrix estimate and interference-and-noise covariance matrix estimate to select an optimal RI value and associated PMI value, wherein the restricted number of RI hypotheses is in accordance with a run-time estimated CSI acquisition capability of the CSI acquisition circuitry; and execute the joint RI-PMI search based on the selected RI hypotheses.

Abstract: A device and a method for job scheduling at a signal processing component with limited queue availability, in response to a request for one or more new jobs, the method comprising: calculating a metric for each job in the queue and a request metric for the one or more new jobs, wherein each job's metric is based on a difference between an estimate output of executing the job in current conditions and a previous output of the job; determining a minimum metric from the metrics calculated for the jobs in the queue; and comparing the minimum metric to the request metrics to determine whether to schedule to new job for execution.
