Abstract

This technology pertains to a communication control device and method and a wireless communication device and method by which it is possible to retransmit data for which demodulation has failed, with a higher degree of reliability. A communication control device functioning as an AP1 causes a data-including Data signal to be held in a first wireless communication device functioning as an AP2, and causes the first wireless communication device to operate such that when a transmission request is received, the Data signal is transmitted to a second wireless communication device that functions as an STA. This technology can be applied to a wireless communication system.

Description

technical field [0001] The present technology relates to a communication control device and method, and a wireless communication device and method, and in particular, to a communication control device and method, and a wireless communication device and method that enable retransmission of data whose demodulation has failed with higher reliability. Background technique [0002] In recent years, due to the popularity of wireless devices, congestion of wireless networks has occurred. In a congested wireless network, there is a possibility of communication failure due to communication interference. Generally, in wireless communication, a transmitter retransmits (retransmits) a signal that a receiver fails to receive, and thus the quality of communication is guaranteed. [0003] It is conceivable that depending on the state of the receiver, the retransmitted signal may also not be received, and the communication quality may not be guaranteed. Conceivable examples include the si...
