摘要： Systems and methods for communicating between a wireless station and a base station are provided. A base station can allocate both a TDD channel and an FDD channel pair for communicating with a wireless station. The base station can transmit and receive unicast messages using the time slots of the TDD channel or can transmit multicast messages over all time slots of the TDD channel.

摘要： Systems and methods for supporting multiple wireless communications technologies are provided. When a first and second base station operate according to different wireless communication technologies on the same carrier frequency in different cells or on different carrier frequencies in the same cell the frame structure of each base station is controlled in such a way that idle periods of transmissions from one base station are aligned with idle periods of the other base station. When the first and second base stations are located in the same cell and operate on the same carrier frequency the frames of the first and second base stations are time-interlaced.

摘要： A system and method for handoff are provided. A mobile station performs a make-before-break handoff of a control channel between a serving and target base station and a break-before-make handoff of a traffic channel between the serving and target base stations. The traffic channel handoff is performed after the control channel handoff has completed.
