Hierarchical beamforming method and base station and user equipment using the same
First Claim
1. A hierarchical beamforming method, adapted to a base station, and comprising:
- performing a network entry procedure via a plurality of coarse beams by respectively using a superframe header of a superframe corresponding to each of the coarse beams;
receiving a success message of the network entry procedure via one of the coarse beams;
wherein the success message comprises a random access preamble;
identifying said one of the coarse beams as the preferred coarse beam, so as to transmit back a network entry done message in response to the success message by using the preferred coarse beam; and
performing a user equipment connection via a plurality of fine beams within a direction range of the preferred coarse beam, so as to determine a preferred fine beam from the fine beams by using frame headers of a plurality of basic frames respectively corresponding to the fine beams, and performing a data packet transmission by using a packet transmission block of the basic frame corresponding to the preferred fine beam.

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.
