Abstract

The invention discloses an improved dual-band Femtocell (DBF) unlicensed channel access method to realize spatial multiplexing. According to relative distance between the DBF and a WiFi AP, the method has two situations: when the DBF and the WiFi AP are visible to each other, the method is simplified into an existing method, that is, the DBF and the WiFi AP occupies an unlicensed channel at different time, and all of DBF users in a DBF schedulable coverage range carry out data transmission; and when the DBF and the WiFi AP are invisible to each other, if the WiFi AP carries out data transmission with WiFi users in the coverage overlapped range, the DBF cannot take up the unlicensed channel, and if the WiFi AP carries out data transmission with WiFi users outside the coverage overlapped range, the DBF can take up the unlicensed channel and calls DBF users outside the coverage overlapped range to carry out data transmission. Compared with an existing DBF unlicensed channel access method, the method realizes maximized utilization of unlicensed frequency band frequency spectrum resources on the basis of ensuring WiFi system performance, and improves the system performance.

Description

technical field [0001] The present invention relates to an improved method for accessing an unlicensed channel of a dual-mode micro base station, in particular to an improved method for accessing an unlicensed channel of a dual-mode micro base station under the coexistence scenario of LTE (LongTerm Evaluation, LTE) and WiFi (Wireless Fidelity, WiFi). An entry mechanism belongs to the technical field of wireless communication. Background technique [0002] With the rapid development of mobile applications and the rapid growth of mobile data services, the pressure to increase the capacity of cellular network systems is increasing. The bottleneck of improving system capacity lies in the scarce licensed frequency spectrum resources. In order to further improve the performance of cellular networks, meet users' demands for peak rate and data flow, provide a good user experience, and alleviate the current crisis of spectrum scarcity, 3GPP proposed a new The coexistence mechanism o...
