摘要： A method and apparatus for minimizing interference in a wireless communication system. A base transceiver station transmits and receives over a first frequency band and a second frequency band. The maximum range of the first frequency band can be smaller than the maximum range of the second frequency band. Alternatively, the maximum range of the first frequency band can be larger than the maximum range of the second frequency band. Further, the maximum range of the second frequency band can vary based upon factors such as the capacity of the first frequency band and the amount of interference on the first frequency band. A control channel for the second frequency band which is measured for determining whether to handoff from the first frequency band to the second frequency band can be transmitted within the first frequency band.

摘要： A method and system for controlling handoffs in radiocommunication systems using a softzone concept are described. Soft handoff is permitted between members of a particular softzone, but not between members of different softzones. Hard handoff is permitted between members of different softzones, but not between members of the same softzone.

摘要： A plurality of base stations are operated in CDMA macrodiversity mode to communicate a message to a mobile station via an air interface. If the message is successfully communicated to one of the base stations via a packet network, the base station communicates the message to the mobile station via the air interface using CDMA. Otherwise, the base station refrains from communicating any message to the mobile station.
摘要翻译： 多个基站在CDMA宏分集模式下操作，以经由空中接口向移动台传送消息。 如果消息通过分组网络成功地传送到基站之一，则基站通过使用CDMA的空中接口将消息传送到移动台。 否则，基站禁止向移动台传送任何消息。
