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 invention relates to an improved dual-mode micro base station unlicensed channel access method, in particular to an improved dual-mode micro base station unlicensed channel access under the coexistence scenario of LTE (LongTerm Evaluation, LTE) and WiFi (Wireless Fidelity, WiFi) Access mechanism belongs to the field of wireless communication technology. Background technique [0002] With the rapid development of mobile applications and the rapid growth of mobile data services, the pressure on the increase of cellular network system capacity is increasing. The bottleneck for increasing the system capacity lies in the scarce authorized frequency spectrum resources. In order to further improve the performance of cellular networks, meet user requirements for peak rates and data traffic, provide a good user experience, and alleviate the current spectrum scarcity crisis, 3GPP has proposed a new The coexistence mechanism of LTE and WiFi in the unlicensed freq...
