transmitting, by the base station, the uplink/downlink configuration information to at least one terminal via a Downlink Control
Indicator (DCI) message, so that the at least one terminal parses the DCI message in accordance with predetermined DCI configuration
information and determines its own uplink/downlink configuration from the DCI message, the DCI message comprising at least
one uplink/downlink configuration information domain, at least one of the uplink/downlink configuration information domains
in the DCI message being parsed by the at least one terminal, the uplink/downlink configuration information domain being configured
to carry the uplink/downlink configuration information,

wherein the DCI configuration information further comprises a length of a valid information domain in the DCI message, or
a length of a vacant region in the DCI message.
