A periodic quiet interval is provided for base stations attempting to access a shared transmission medium in NR-U. The base station activates a quiet interval at a periodic interval and transmits on the medium based on the quiet interval. The base station may reduce a Tx power, not transmit, and/or may increase a minimum value of a contention window for BEB during the quiet interval. The base station may receive a request from a second base station to activate the quiet interval, and may determine if a Tx power of the base station is larger than the maximum Tx power of the second base station. The base station may also receive the request as relayed through a UE. The quiet interval can thus ameliorate a starvation effect of BEB in NR-U by allowing base stations with smaller Tx power greater opportunity to control the medium while maintaining BEB in NR-U.
