Abstract

Provided is a communication apparatus including a first communication unit for performing communication using a carrier having a first frequency, a second communication unit having a plurality of antennas, for performing communication using a carrier having a second frequency, a first communication processing unit for processing a signal received by the first communication unit and causing to transmit a signal, and a second communication processing unit for processing a signal received by the second communication unit and causing to transmit a signal. The second communication processing unit includes a synchronization unit for specifying a start position of a second transmission request in which a plurality of transmission beam patterns are set in one packet based on information indicating reception initiation, and an automatic gain control unit for performing automatic gain control based on a first automatic gain control setting value.
