Abstract: The present disclosure proposes a hierarchical beamforming method and a base station and a user equipment using the same. The method includes following steps. A network entry procedure is performed via a plurality of coarse beams by using a superframe header of a superframe corresponding to each of the coarse beams. In response to a success message associated with the network entry procedure being received, a network entry done message is transmitted by using a preferred coarse beam among the coarse beams. A user equipment (UE) connection is performed via a plurality of fine beams within a direction range of the preferred coarse beam, so as to determine a preferred fine beam by using a frame header of a basic frame corresponding to each of the fine beams, and perform a data packet transmission by using a packet transmission block of the basic frame corresponding to the preferred fine beam.

Abstract: UE-specific search spaces (UE-SS) for a carrier-aggregated communication system are introduced to decrease the number of blind decoding attempts, decrease downlink control information (DCI) blocking probability, and maintain good blind decoding performance. In the proposed control channel allocation method, the control channel searching method and the communication apparatus thereof, the UE-specific search spaces are extended except control channel element (CCE) aggregation level one. Further, a new CCE aggregation level is created in the UE-specific search spaces. The sum of the number of control channel candidates for all aggregation levels is bounded by the maximum number of PDCCH candidates. In addition, uplink MIMO grant command is just allocated in a pre-configured component carrier or a set of pre-configured component carriers, but uplink MIMO grant command is not allocated in the remaining component carriers.
