This disclosure provides coexistence strategies for a combined wireless communications device using multiple wireless protocols, such as WLAN and LTE. One or more periods having increased interference potential during an upcoming communication event of one wireless protocol may be identified and the transmission duration of another wireless protocol may be dynamically adjusted to reduce interference. In one aspect, a first period of potential interference during an upcoming LTE transmission may be predicted based on allocated LTE transmission power. The duration of the transmission may be adjusted so that a response to the transmission does not arrive during the first period. In another aspect, a second period of potential interference during an upcoming LTE reception may be predicted based on an estimated quality of LTE reception. The duration of the transmission may be adjusted so that the transmission does not being during the second period.
