Title: FREQUENCY SPECTRUM ACCESS METHOD AND APPARATUS
Abstract:
Respecting the condition of a multi-channel wireless network using a time domain separation method to achieve basic communication coexistence, the present invention discloses a frequency spectrum access method, comprising: selecting from amongst all the LTE-U users in the multi-channel wireless network an LTE-U user Celli to co-work with 802.11 users; when (m-1) groups of 802.11 users on a different channel to the LTE-U user Celli respectively access an ith wireless channel, calculating the throughput respectively acquired by the (m-1) groups of 802.11 users and the throughput attenuation caused to the LTE-U user Celli; and selecting a group of 802.11 users therefrom to access the ith wireless channel in an LTE-U time period. Also disclosed in the present invention is a frequency spectrum access apparatus. The present invention achieves the objective of improving the throughput of 802.11 users and the global network when 802.11 users and LTE-U users coexist.
