CHANNEL OCCUPANCY DETERMINATION METHOD AND APPARATUS

摘要

Embodiments of the invention disclose a channel occupancy determination method and apparatus, the method comprising: filtering according to geographical locations of small cells and a clear channel detection result, small cells satisfying certain conditions so as to form a first set; filtering, according to interference levels between small cells, small cells satisfying certain conditions and grouping into a second set, and grouping other small cells into a third set; dividing, according to priority levels and the geographical locations of the small cells, the small cells in the second set into an active set and a restrained set; send transmission control signaling to the small cells of the third set, the active set and the restrained set, such that the small cells of the third set and the active set start data transmission after receiving the transmission control signaling, and the small cells of the restrained set, during the channel occupancy, enter a non-transmitting state after receiving the transmission control signaling. The invention can improve the rationality of channel resource allocation when a small cell system internal portion, an LAA system and a Wi-Fi system are used together, improving system performance.
