Abstract
A control apparatus may wirelessly communicate with a terminal apparatus. When a random access preamble is received from the terminal apparatus, if the random access preamble is not based on a setting notified by the control apparatus, the control apparatus may scramble communication with the terminal apparatus after the random access preamble is received, using a scrambling sequence that is based on second identification information different from first identification information corresponding to the control apparatus.
