[0004] Spectrum allocation methods for wireless networks such as cellular networks have received widespread attention. Many spectrum allocation methods based on optimization theory, graph theory, game theory, and biological inspiration have been proposed to suppress interference between sites and improve frequency band utilization. Spectrum allocation methods for shaped network coverage are still rare

Embodiment Construction
[0020] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0021] Such as figure 1 As shown, the wireless network with amorphous coverage has N base stations and K nomadic stations. Users dynamically enter / leave the area covered by base stations and nomadic stations, and the number of users is not fixed. Users within the coverage area of the base station can directly connect to the base station, but the number of users in dense areas may exceed the capacity of the base station, requiring nomadic sites to share traffic. Users who are not within the coverage of the base station are connected to the base station by the nomadic site through relay forwarding. Nomadic stations move to users not within the coverage of the base station and users in dense...

The invention discloses a spectrum allocation method for amorphous network coverage. The method comprises the following steps: a wireless network with amorphous network coverage is provided with a plurality of base stations and a plurality of nomadism stations; each base station senses an idling frequency band within an own coverage range; then each base station distributes the acquired frequency band to a communication link to enable a user and the base station to perform uplink communication; all the base stations report the idling frequency band sets to a mobile switching center, which find out the same frequency band sets; the mobile switching center distributes the same frequency bands to the non-interfering nomadism stations and near users at first and then distributes the rest non-overlapping frequency bands to the rest nomadism stations and near users; both the frequency bands of the nomadism stations and the frequency bands of the near users not within an interference distance are distributed to remote users connected with the nomadism stations and users in dense areas. According to the method, frequency band distribution is performed according to available frequency band information acquired via base station sensing and interference information among the nomadism stations, so that the capacity and the coverage of the wireless network are improved, and the frequency band utilization rate is increased; the spectrum allocation method is applicable to spectrum distribution for the wireless network with the amorphous network coverage.
Description
technical field [0001] The invention relates to the technical field of wireless communication, in particular to a frequency spectrum allocation method covered by an amorphous network. Background technique [0002] Spectrum resources were previously managed by the government, using a fixed authorization allocation method. The measured data in recent years shows that the utilization rate of the allocated frequency band is not high, and there are a lot of idle time and space. On the other hand, the rapid development of new wireless communication systems requires more frequency bands to meet the quality of communication service requirements. In the case of limited remaining exploitable spectrum resources, improving frequency band utilization becomes a realistic approach. Cognitive radio technology is expected to realize this vision, which allows unlicensed users to opportunistically share the frequency band of licensed users, so that the allocated frequency band can accommodat...
