    Abstract: An enhanced Node B (eNB) for precoding is generally described. In some embodiments, a first precoding-matrix indicator (PMI) and a second PMI is received on an uplink channel from user equipment (UE). Symbols for multiple-input multiple output (MIMO) beamforming may be precoded by the eNB using a precoder matrix recommended by the first and second PMIs, for a MIMO downlink orthogonal frequency division multiple access (OFDMA) transmission. The first PMI and the second PMI are calculated by selecting a representative codeword that is indexed by i1 and i2 for a plurality of 2TX constituent beams, the 2TX constituent beam that provides the best system evaluation metric. The i1 index for wideband and the i2 index for each subband are identified from the defined 2TX constituent beam.

    Abstract: An apparatus of a user equipment (UE) may include memory and processing circuitry coupled to the memory. The processing circuitry may be configured to estimate a communication channel for a multi-carrier signal based on a received reference signal, the multi-carrier signal aggregating a plurality of component carriers. During a transmission time interval of the multi-carrier signal, the UE can perform a global search over a beam search space to obtain a beam index recommendation for a component carrier of the plurality of component carriers. The beam index recommendation corresponds to a maximized channel quality metric of the estimated communication channel and is indicative of a beam grid within the beam search space. The UE can perform a localized search of a subset of the beam search space to obtain a second beam index recommendation for a second component carrier of the plurality of component carriers.

    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.
