The cell phone tower will issue each phone with a time slot and frequency when it is allowed to transmitt and when to receive. When the phone is in standby the time slots will be very small and far between. But when the phone starts using data or a phone call is made the time slots become longer and more frequent to allow for higher bandwidth. The cell tower will make sure that no two phones are given the same time slot on the same frequency if they are close enough to interfere with each other. This often requires cooperation with other nearby cell towers.
