In a communication system, an access point in communication with one or more stations is configured to shift the start of transmission of its downlink data. The access point may automatically shift the transmission of the downlink data in response to receiving downlink data transmitted by a neighboring access point. Shifting the start of transmission of its downlink data permits stations to correctly synchronize to the downlink data. The transmission of data may be synchronized to a synchronization event. In some instances, the access point updates its downlink data with a value corresponding to the shift. The access point may not shift the transmission of the downlink data if the signal strength of the received downlink data is below a threshold.
