The invention relates to a method for dynamically indicating a TDD reconfiguration to the
mobile station by encoding the dynamic TDD re-configuration indication into the DCI or CRC calculated for the DCI. In one embodiment, the TDD configuration indication is implicitly encoded as an RNTI into the CRC, when scrambling the CRC for the DCI with a TDD-RNTI. In another embodiment, the TDD configuration indication is part of the DCI
payload, while the CRC for the DCI is scrambled with a
cell identifier, identifying the target
cell for which the dynamic TDD re-configuration is to be applied. In still another embodiment, the TDD configuration indication is part of the DCI
payload, where the DCI
payload further includes an invalid parameter indicating to the
mobile station that the DCI carries the TDD configuration indication.
