[0012] Although the C-RAN network has the advantages of reducing energy consumption and network operation and maintenance costs, the C-RAN network is still a network designed based on traditional radio thinking. The network does not have intelligent cognition of the radio environment and adjusts radio transmission parameters to maximize the network ability to benefit

Embodiment Construction
[0030] Embodiments of the present invention provide a new type of C-RAN network. In addition to the advantages of low energy consumption of the C-RAN network and network operation and maintenance costs, the new type of C-RAN network also has the ability of cognitive radio to use spectrum flexibly and intelligently. Compared with the existing C-RAN network, the network capacity can be improved.
[0031] The new C-RAN network provided by the embodiment of the present invention can be realized by adding related capabilities of cognitive radio spectrum sensing and resource allocation in the existing C-RAN network.
[0032] Hereinafter, taking the improvement of the existing C-RAN network as an example, the embodiments of the present invention will be described in detail with reference to the accompanying drawings.
[0033] figure 2 It shows the C-RAN network architecture in the embodiment of the present invention, which includes a centralized processing center and multiple RRUs,...

The invention discloses a wireless frequency spectrum resource allocation method and equipment, which are applied to C-RAN. The method includes: the centralized processing center receives the signals on the cognitive radio spectrum sensing frequency points collected and reported by each RRU, and accordingly determines the occupancy of the cognitive radio spectrum sensing frequency points at the positions of each RRU, and according to each RRU Cognitive radio spectrum sensing frequency occupancy at the location, allocate wireless spectrum resources for the cells corresponding to each RRU, allocate DU resources for processing baseband signals for the cells corresponding to the RRU, and reconfigure the working frequency of the RRU point. By adopting the present invention, the perception and resource allocation of cognitive radio frequency spectrum resources can be realized based on the C-RAN network.
Description
technical field [0001] The present invention relates to the field of wireless communication, in particular to a method and device for allocating wireless spectrum resources. Background technique [0002] With the rapid development of the mobile communication industry, the contradiction between the growing demand for broadband wireless communication and the limited spectrum resources is becoming increasingly obvious. Although the LTE (Long Term Evolution, long-term evolution) system has adopted OFDM (Orthogonal Frequency Division Multiplexing, it is Cross-frequency division multiplexing), MIMO (Multiple-Input Multiple-Output, multiple-input multiple-output) and other technologies to improve spectrum utilization, but these cannot fundamentally solve the problem of spectrum resource shortage. With the rapid development of mobile services, telecom operators will face a more severe problem of spectrum resource shortage. [0003] On the other hand, the spectrum usage of some wire...
