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： A first amount of bandwidth is allocated to a first wireless device to send signal quality information to a base station. Based on a first indicator of wireless link conditions associated with the first wireless device, and a second indicator of wireless link conditions associated with a second wireless device, a second amount of bandwidth is allocated to the first wireless device to send signal quality information to the base station.

摘要： A plurality of ranging processes are performed to monitor a status of a wireless link associated with a device identifier. A ranging request that includes the device identifier and a message skip indicator is received. It is determined that the device identifier is already associated with the wireless link. A duration since a previously completed ranging process is determined. Based on the duration, and the message skip indicator, it is determined whether to respond to the ranging request.

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.
