In Orthogonal Frequency Division Multiple Access (OFDMA), there are multiple sub-channels which enable multiple stations to transmit concurrently on different sub-channels. The stations can obtain the channel information of all the sub-channels at each time instant. Carrier Sense Multiple Access with Collision Avoidance (CSMA/CA) allows different stations to randomly contend for the available subchannels from the time domain to avoid collision with each other. This gives a resource in time and… CONTINUE READING
