Abstract
A node of a wireless network is configured to arrange a frequency division duplex communications link from the node to a user equipment using a downlink frequency carrier having a downlink frequency bandwidth, and from the user equipment to the node by selectively using either a first uplink frequency carrier having a first uplink frequency bandwidth or a second uplink frequency carrier that is spaced apart in frequency from the first uplink frequency carrier and having a second uplink frequency bandwidth. The first uplink frequency carrier may initially be assigned to the user equipment, and the user equipment may be subsequently selectively handed over the second uplink frequency carrier, while continuing to use the downlink frequency carrier. Related nodes, user equipment and operating methods are described.
