Abstract:
The present disclosure provides a wireless communication network system based on centralized control and content delivery, comprising a centralized controller, a core network data forwarding unit, a core network data cache unit, and at least one distributed base station. The centralized control and content delivery control can be performed by the wireless communication network system provided by the present disclosure. In this manner, the user experience can be guaranteed, the centralized control can be realized, and the load of the base station equipment can be reduced to the largest extent. At the same time, the data interaction between base station and internet can be reduced, and thus the occupancy of bandwidth resources can be reduced accordingly.

The present invention relates to the technical field of wireless communication, and discloses a method for frequency reuse based on cellular network. The method comprises the following steps: dividing the whole cellular network into a plurality of different cell clusters, wherein each cell cluster comprises three cells, every two of them being adjacent to each other; for each cell in a cell cluster, dividing the cell into a central area and an edge area according to the coverage of the cell; dividing the whole available frequency band of the network according to the user distribution and service distribution in the cell cluster; allocating divided frequency bands to the central area and the edge area in the cell cluster respectively according to preset rule; and applying the method for frequency reuse to other cell clusters, thus achieving the frequency reuse of the whole network. With the method, the average spectrum frequency efficiency of the cellular network can be improved, and interference among cells can be effectively suppressed.
Abstract:
The present disclosure relates to the technical field of LTE-A, and discloses a method for air interface synchronization between base stations. A base station to be synchronized, which simultaneously monitors a plurality of neighboring base stations, can select one neighboring base station to perform time-service synchronization in accordance with different criteria in order, such as whether CoMP is necessary, the time-service hop count, time-service delay, and the CQI level (channel quality indicator) and the like. That is, the most suitable synchronization source is determined according to a certain priority order. Such solution both applies to a phase of initial establishment of air interface self-synchronization between base stations, and also to a phase of periodic synchronization maintenance. In addition, the technical effect of such solution is particularly prominent in the case of intensively arranged Small Cells.

The invention relates to the technical field of wireless communication, and provides a method for joint optimization of schedule and resource allocation based on a genetic algorithm, which is applied in a CoMP communication system. The method includes steps of: S1, encoding chromosome; S2, initializing setting; S3, computing fitness value; S4, determining whether the optimal solution is better than an elite: if yes, updating the elite and executing S5, and if no, turning to S5; S5, determining whether a predetermined generation of population has been generated or not, if no, executing S6, otherwise, turning to S8; S6, participating reproduction process to generate two offspring chromosome individuals; S7, determining whether a predetermined number of offspring chromosome individuals have been generated, if yes, turning to S3 to compute again; otherwise keeping on reproduction; S8, performing schedule and resource allocation according to a solution corresponding to the elite. Under the condition of satisfying schedule limitation and power limitation, the method can, by uniting schedule and resource allocation, efficiently optimize system performance with less computing complexity.
