Embodiments of methods and systems for using both new and older modulation schemes in PLC networks—thereby supporting legacy systems—are disclosed. In one embodiment, common frames that need to be understood by all nodes to support the network will be sent two or more times using different modulation techniques. For example, all broadcast frames, such as beacon requests, beacons, and route requests may be transmitted once with differential modulation and once with coherent modulation. In one configuration, the beacons with differential modulation may be transmitted in one beacon period, and the beacons with coherent modulation may be transmitted in another beacon period. In another configuration, the differential and coherent beacons for a particular tone mask are transmitted one after the other and before any other tone mask beacon is transmitted.

The invention provides a resource allocation and interference suppression method based on non-cooperative game in an LTE system. First, a multi-cell LTE network interference model is established by adoption of soft frequency reuse, and then, a utility function based on the price mechanism is established through consideration on users' demand for quality of service and energy consumption based on the non-cooperative game theory, a power iteration algorithm maximizing the utility function is given, and resource allocation and interference suppression can be realized through iterative solution.

Only pricing information exchange is needed between the cells, and distributed implementation is easy in actual systems. Therefore, the resource allocation and interference suppression method of the invention has good application prospect.
