Techniques, apparatuses, and systems for dynamically changing downlink and uplink allocations can include operating a base station under time division duplexing to communicate with one or more mobile devices using a frame structure, adjusting a downlink-uplink ratio to change an allocation between uplink and downlink data capacities in the frame structure, determining a mute interval based on the adjusted downlink-uplink ratio, generating mute information based on the mute interval to identify the one or more areas of the frame structure effected by the allocation change, and transmitting the mute information to the one or more mobile devices.
