Abstract: The present technology relates to a communication apparatus and a method that allow for synthesis of information using an original signal and a retransmission signal for retransmitting information of the original signal whose demodulation has failed, in wireless communication with independent physical layer and MAC layer. Information is transmitted regarding a configuration of a retransmission signal for retransmitting information of an original signal whose demodulation has failed to a sender of the retransmission signal, and the retransmission signal transmitted from the sender is received on the basis of the information regarding the configuration of the retransmission signal transmitted. The present disclosure is applicable, for example, to a transmission/reception apparatus, a communication apparatus, an information processing apparatus, electronic equipment, a computer, a program, a storage medium, and a system, and so on.

Abstract: To provide an excellent communication apparatus and communication method which operates with a basic service set belonging to an extended service set. A wireless terminal transmits a frame in which BSS-color and ESS-color which respectively identify a BSS and an ESS to which the own wireless terminal belongs are described. Further, part of a region for storing ESS-color is used as a region for storing BSS-color to secure the number of pieces of BSS-color sufficient to avoid overlapping. An STA stores statistical information regarding a received frame in association with BSS-color and ESS-color and performs cooperative operation within the ESS or between the ESSs.
