Abstract:
The present disclosure relates to an electronic apparatus and server in a wireless communication system, and wireless communication method. An electronic apparatus according to the present disclosure is configured to be a transmitting apparatus in D2D communication, and comprises: a transceiver; and one or more processing circuits configured to perform the following operations: enabling, on the basis of the electronic apparatus and position information of a receiving apparatus corresponding to the electronic apparatus, the transceiver to request a server in a wireless communication system for beamforming information; if the electronic apparatus does not receive beamforming information from the server, triggering a beam training process between the electronic apparatus and the receiving apparatus; and after the beam training process is completed, enabling the transceiver to report a result of the beam training process to the server. Employing the electronic apparatus, server, and wireless communication method according to the present disclosure enables combination of advantages of two beamforming techniques, i.e., adaptive beamforming and predefined codebook beam switching, thus achieving high transmission performance on the basis of a simple algorithm.
