Step 500: Start.
Step 502: Transmit system information on the DL-only carrier to a communication device, wherein the system information does not comprise at least one information element for a UL transmission.
Step 504: End.
According to the process 50, the network may transmit system information on the DL-only carrier to a communication device, wherein the system information may not include at least one information element for a UL transmission and the at least one information element is mandatory to be present in the system information according to a 3GPP standard. The network may realize the process 50, when communicating with a communication device realizing the process 40. For example, the system information may include (or simply be) SIB2 which further includes an information element prach-Config which is mandatory to be present as defined in the LTE/LTE-A system. That is, the system information may be defined to include the information element. In one example, the DL-only carrier may be configured for a MBMS service. That is, the DL-only carrier may be used by the network for providing (e.g., broadcasting) the MBMS service to the communication device. In another example, the DL-only carrier may be configured for a DL transmission to the communication device in a CA. In one example, the system information may include a new TDD-Config which indicates a UL/DL configuration comprising only DL subframes.
