RADIO RESOURCE ALLOCATION OF UNLICENSED FREQUENCY BANDS BASED ON UTILIZATION RATE OF PRIMARY AND SECONDARY CHANNELS ON ONE OF THE SHARING TECHNOLOGIES

摘要

A network node operates in accordance with a first radio access technology in a frequency band, wherein communication according to a second radio access technology may occupy one or more of the radio resources of the frequency band. A method comprises receiving a beacon signal associated with the second radio access technology and determining whether or not the beacon signal comprises information indicative of which of the radio resources of the frequency band are used as primary and secondary channels, respectively, in accordance with the second radio access technology. The method also comprises determining a communication activity rate of at least one of the radio resources of the frequency band and selecting one or more of the radio resources of the frequency band based on the determined communication activity rate, and allocating one or more of the selected radio resources to communication in accordance with the first radio access technology.
