Please note that the at least one information element in the above description, examples and processes may include at least one of the following parameters: RACH-ConfigCommon, PRACH-ConfigSIB, PUSCH-ConfigCommon, PUCCH-ConfigCommon, SoundingRS-UL-ConfigCommon, UplinkPowerControlCommon, UL-CyclicPrefixLength, UplinkPowerControlCommon-v1020 and TDD-Config. That is, the information element(s) may include a subset of (which may include all of) the above parameters.

Furthermore, when the DL-only carrier is a carrier of a TDD band, the system information may include a new TDD-Config which indicates a new UL/DL configuration including only DL subframes without any UL subframe. Alternatively, other system information may include the new TDD-Config. That is, the communication device may determine that the carrier of the TDD band is the DL-only carrier according to the new TDD-Config, even if the network does provide the original TDD-Config (e.g., for one of the UL/DL configurations 0-6 where each includes at least one UL subframe) in the system information.

Those skilled in the art should readily make combinations, modifications and/or alterations on the abovementioned description and examples. The abovementioned steps of the processes including suggested steps can be realized by means that could be a hardware, a firmware known as a combination of a hardware device and computer instructions and data that reside as read-only software on the hardware device, or an electronic system. Examples of hardware can include analog, digital and mixed circuits known as microcircuit, microchip, or silicon chip. Examples of the electronic system can include a system on chip (SOC), system in package (SIP), a computer on module (COM), and the communication device 20.
