摘要：A dynamic carrier selection method and system permit units operating on a firstcarrier (0, 1, 2, 3, 75, 76) to change to a second carrier (0, 1, 2, 3, 75, 76) when performanceof the first carrier (0, 1, 2, 3, 75, 76) becomes unacceptable. Carrier quality measurementsare taken (503) in which carrier quality is a function of interference (I) and multi-pathfading and carrier-signal strength (C). The carriers (0, 1, 2, 3, 75, 76) are ranked accordingto measured quality in a carrier candidate list. The carrier candidate list is used to permitunits (403) to determine which carrier (0, 1, 2, 3, 75, 76) they should switch to (402) whenthe carrier (0, 1, 2, 3, 75, 76) they are currently operating on is determined to haveunacceptable performance. Carrier measurements are retaken (503) in response to acarrier change by unit (403) or a predetermined time period having elapsed.
