Abstract
This disclosure provides systems, methods, and apparatus for reducing or avoiding interference between communications of one base station-user equipment pair and communications of another base station-user equipment pair. A first user equipment can monitor a timing offset between the communications and send the timing offset to a first base station that services the first user equipment. The first base station time advances a window of time during which it receives uplink signals from the first user equipment. The base station also sends a time advance value and instructions to the first user equipment to advance a window of time during which the first user equipment transmits uplink signals to the first base station. The timing advance value is based on the timing offset value determined by the first user equipment. Thus, a gap period between uplink and downlink windows is increased, thereby reducing interference.
