Abstract:
1. A method of operating a node for a communication system, comprising: operating the node according to a first transmission/reception (TX/RX) setup with first node identification (ID) for at least one cell; monitoring a load on the node; determining whether the load has crossed a threshold; and when the load has crossed the threshold, gradually transitioning the node from operating according to the first TX/RX setup with the first node ID, to operating according to a second TX/RX setup with a second node ID for said at least one cell, wherein the gradually transitioning includes adding at least one free sub-frame usable for transmitting a signal by the node operating according to the second TX/RX setup, to sub-frames used by the node operating according to the first TX/RX setup, operating the node at the same time as two different nodes with the first and the second node IDs, respectively, while gradually transitioning, and the second TX/RX setup differs from the first TX/RX setup by including a different number of antennas, and at least one of a larger or a smaller bandwidth, and a different number of component carriers or subcarriers.
