Abstract:
1. A communication apparatus, comprising: a reception unit that receives precoding information from user equipment; a selection unit that variably controls an amount of the precoding information, which is to be notified to another communication apparatus via a backhaul, in response to positions of frequency resources; and a transmission unit that transmits the precoding information to the other communication apparatus in accordance with the amount of the precoding information controlled by the selection unit, wherein the selection unit correlates information of future transmission signal power, information of future transmission signal power density, information of normalized transmission signal energy, information of normalized transmission signal energy density, and information representing a communication quality for each of the frequency resources in a serving cell, with the amount of the precoding information at a position of the corresponding frequency resource.
