Abstract
There is provided a communication control device that controls wireless communication in compliance with a time division duplex (TDD) scheme, the communication control device including: a selection unit configured to select a link direction configuration for the wireless communication among a plurality of candidates for the link direction configuration which indicates a link direction in units of sub-frames of a radio frame which includes a plurality of sub-frames; and an application unit configured to apply the selected link direction configuration to the wireless communication. The plurality of candidates include at least one of a link direction configuration dedicated to a downlink and a link direction configuration dedicated to an uplink.
