Dynamic channel allocation of TD-SCDMA: Based on this analysis, through intra-cell switching assisted by mobile stations, mobile stations working in interference environments can avoid both interfering time slots and interfering wireless carriers. There are three different forms of dynamic channel allocation: · If there is local interference in the original time slots of the currently used wireless carrier, dynamic channel allocation in the time domain can be performed by changing the time slots; · If interference occurs in all time slots of the currently used wireless carrier, dynamic channel allocation in the frequency domain can be performed by changing the wireless carrier; · By selecting the most favorable direction decoupling between users, dynamic channel allocation in the space domain can be performed. Dynamic channel allocation in the space domain is achieved through the directivity of smart antennas, and it is generally used together with dynamic channel allocation in the time domain and frequency domain. By combining the dynamic channel allocation technology in the time domain, frequency domain and space domain, TD-SCDMA can automatically minimize the interference of the system itself. In this way, the advanced system design of TD-SCDMA can reflect the advantages of its basic TDMA/TDD solution, thereby achieving the best spectrum efficiency and service quality, and also enabling operators to obtain the best economic benefits.
