摘要：
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.
