Communication device and method for packet communications in a contention-free period

摘要

A communication device includes a memory, and a processor coupled to the memory and configured to transmit a first packet including a first information within a contention-free period assigned to the communication device, the first packet storing last data to be transmitted in the contention-free period, the first information indicating presence of remaining data to be transmitted in the contention-free period, and, after transmit the first packet, to transmit a second packet including a second information within the contention-free period, the second information indicating absence of remaining data to be transmitted in the contention-free period.
