METHOD AND NETWORK NODE FOR SHARING RADIOFREQUENCY SPECTRUM FOLLOWING A CONTENTION BASED PROTOCOL WITH DETERMINATION OF TRANSMISSION TIME DURATION

摘要

A method and system for time-sharing radiofrequency spectrum resources between at least two wireless networks where the transmission time duration of a network node configured to control transmissions in a first wireless network is adjusted based on the estimated number of active wireless devices operating in a second wireless network. The shared channel is accessed following a contention based, CSMA/CD, protocol, In one aspect, a method is provided for the network node which includes after a first wireless network transmission in the first wireless network, determining a start time of a contention-based transmission in the second wireless network, estimating a number of active wireless devices operating in the second wireless network based on the start time, and adjusting a transmission time duration for a subsequent first wireless network transmission based on the number of active wireless devices estimated.
