摘要： An enhanced access terminal (AT) that can serve as a “proxy wireless over-the-air backhaul or relay” is provided, to connect a base station with no backhaul to its neighboring fully functional base station that is connected to the NMS. In a further embodiment, an architecture and protocol for storing and retrieving data at the base station lacking backhaul is provided, and, using that information, a mechanism by which the ATR can communicate the format information to the source to improve interference cancellation at the base station lacking backhaul, and neighboring base stations, due to backhaul transmission from the AT's routing and relaying capability.

摘要： An access-terminal routing methodology is provided that may be used to enable a wireless, meshed backhaul between base stations using existing wireless-access resources (time, bandwidth, code-space, power), protocols, and base station infrastructure. Accordingly, the invention provides a means to extend the coverage of existing networks by adding standalone base stations without wired or specialized wireless backhaul.

摘要： The present invention provides a method of calibrating base station comprising a plurality of antennas and operating in an Orthogonal Frequency Division Multiplex (OFDM) and Time Division Duplex (TDD) mode. One embodiment of the method includes a method of calibrating a base station comprising a plurality of antennas for beamsteering forward link traffic data to a target mobile in a TDD wireless communication system. Each antenna is connected to a corresponding radio via a transmit/receive switch that is configured to switch between a receive path and a transmit path. The method includes transmitting a first signal from a first radio via a first cross-over cable coupled to the first radio and a second radio such that the first signal is received by the second radio. The method also includes transmitting a second signal from the second radio via a second cross-over cable coupled between the first and second radios such that the second signal is received by the first radio. The method further includes determining, based on at least one of the first or second signals, a relative weight that can be applied to traffic signals transmitted from the second radio.

摘要： A wireless communication system includes the ability to determine that a fault condition associated with at least a portion of a cell associated with a base station is likely. Disclosed examples include using information regarding call activity levels of various portions of a cell for determining an expected call activity level for at least one portion of the cell. One example includes using the least active portion of the cell as the portion of interest. Previously observed activity levels provide information to automatically determine an expected relationship between the activity levels of the portions of the cell. Disclosed examples include determining whether a deviation between the actual call activity level and the expected call activity level is statistically significant enough to indicate a fault condition with at least the portion of the cell, which is of interest.
