The invention relates to the design of power sequences for use in a group of sub-areas of a wireless communication system. Each power sequence defines for one of the sub-areas transmission power values for transmissions using a respective one of a plurality of medium access units. For each of the sub-areas of the group, reception quality values are determined for transmissions between an access station serving the sub-area and mobile stations located at an edge of the sub-area. The reception quality values allow meeting system. The reception quality values are then converted for each of the sub-areas into transmission power values of a power sequence.

A method performs communication resource control in at least one cell of a cellular communication network. The cell includes a base station communicating using at least one frequency and the cell is operated according to a time-based frequency reuse technique. A communication between a terminal and the base station is based on a time frame structure including a plurality of time slots. The method includes the step of obtaining, at the base station of the cell, loading conditions of at least one cell among the subject cell and its neighboring cells. The method also includes the step of adapting, at the base station of the cell, at least one parameter of communication resource control of the base station on the basis of the loading conditions obtained. A base station, a terminal, a system, and a computer program product to implement the method.

The disclosure details the implementation of an apparatus, method, and system for an network selector for datacasting in hybrid networks (NSDHN). In one aspect, the disclosure teaches an efficient delivery decision mechanism that takes into account efficiencies that may be achieved by employing one network delivery system over another for any given area. In another aspect, the disclosure teaches how to dynamically select the bearer for IP multicast data delivery in hybrid networks. Also, the disclosure teaches a network delivery selector based on Simulated Annealing and genetic algorithms. The network delivery selector provides an extremely fast mechanism to establish an optimal delivery bearer dynamically. This allows the network delivery selector to combine unicast, multicast and broadcast network bearers in the same hybrid network to exploit their combined best properties and serve as many users as possible.
