摘要： In a conventional Time Division Multiple Access (TDMA) wireless system, the specified distance between a mobile unit and the base transceiver system (BTS) cannot exceed predetermined distances because of time slot synchronization constraints. Furthermore, varying distances between mobile units and the BTS, as well as Rayleigh fading, caused by destructive interference effects between direct and reflected signals, create extreme signal strength variations in the initial uplink signal from the mobile stations. The use of spatially-diverse antennas for receiving uplink signals provides diversity gain and mitigates deep fades. Furthermore, selecting the stronger of the spatially-diverse uplink signals mitigates deep fades and reduces frequency usage in the backhaul frequency band. In this approach to extending TDMA system coverage, in-band translator components are located in the center of remote cells which would normally contain a base transceiver system (BTS). The in-band translators include delay elements to implement slot-by-slot selective spatial diversity and automatic level control in a predictive feedforward fashion. The selective diversity mitigates deep Rayleigh fades, while the dynamic automatic level control drastically reduces the uplink backhaul dynamic range to allow for greater backhaul distances. Predictive feedforward automatic level control also eliminates overload and saturation of the backhaul high power amplifier, normally caused by wide variations in uplink power levels.

摘要： In a conventional Time Division Multiple Access (TDMA) wireless system, the specified distance between a mobile unit and the base transceiver system (BTS) cannot exceed predetermined distances because of time slot synchronization constraints. Furthermore, the varying distances between mobile units and the BTS create timing differences in the random access control channel (RACCH) bursts in the initial uplink signal from the mobile stations. In this approach to extending TDMA system coverage, in-band translator components are located in the center of remote cells which would normally contain a base transceiver system. The in-band translators include a loop back circuit that permits a host BTS to measure the backhaul propagation time delay by sending test access signals between the host BTS and the distant in-band translators. After backhaul timing delay is compensated in the BTS, then the in-band translator uses downlink time slot recovery to synchronize slot-by-slot uplink diversity selection and automatic level control. Recovery of timing bursts on downlink from the BTS allows for determination of burst, frame, and multiframe timing for downlink and uplink in the in-band translator. Processing allows for pre-determination of which uplink time slots that the RAACH signal can appear from the mobile unit. This method allows for automatic level control during RAACH bursts in addition to normal uplink bursts.

摘要： A method and apparatus for dynamically controlling signal power levels in a bi-directional backhaul communication link between a base station and a repeater station is provided. The signal power level of a signal transmitted between a base station and a repeater station is measured at the receiver of the signal. Once the received signal power level has been measured, the power level data based on the received signal power level is automatically transmitted from the receiving station back to the source of the measured signal over the backhaul link. Upon receipt at the source, the power level data is extracted and analyzed to determine if the source needs to alter its transmitted power. Once the power level data is analyzed to determine if a change in the transmitted power is required, the source can automatically respond by increasing, decreasing, or maintaining the transmitted power.

摘要： The invention discloses a method and apparatus for diagnosing a backhaul communications link between a repeater station and a base transceiver station of a wireless communication system. Adjacent and co-channel interference can severely degrade the performance of the backhaul communication link. As a result, the conditions on the backhaul link channels can be continually monitored to ensure optimal performance of the link. Each RF channel on the backhaul communication link is individually diagnosed. A signal is then sent over the RF channel and the signal strength is measured along with any adjacent and co-channel interference. The measured statistics are then sent back to the base transceiver station. In a further embodiment of the invention, the power level of a RF carrier signal on the backhaul communication link is measured and the carrier signal is then turned off. The power levels on the adjacent channels—above and below are then measured. Based on these measurements and other channel statistics, the power level of the RF carrier signal is accordingly adjusted.

摘要： A method and apparatus employing automatic radio frequency (RF) muting and wireless remote control of RF downlink transmission is disclosed for the protection of a downlink amplifier of a wireless repeater system. The present invention has broad application in systems where a RF controller controls the function of a remote RF re-transmitter.

摘要： A method and apparatus for using a loopback capability of a radio frequency (RF) repeater to provide for end-to-end testing without a wireline connection is disclosed. A RF source sends a signaling waveform to the RF repeater. Upon receiving the signaling waveform, the RF repeater enters the loopback mode. The RF source sends another identical signaling waveform to the RF repeater to end the loopback mode. In another embodiment, a base transceiver station (BTS) sends a signaling waveform to an intelligent RF repeater-translator upon detection of a lack of activity. The received signaling waveform places the intelligent RF repeater translator into a loopback mode. If alarms are present in the intelligent RF repeater-translator, the intelligent RF repeater-translator ceases processing and the BTS informs the OMC of the error condition. Otherwise, the loopback mode is entered and BTS initiates testing of the intelligent RF repeater-translator. The loopback mode is discontinued when the intelligent RF repeater-translator receives another identical signaling waveform or after a time-out period elapses. The intelligent RF repeater-translator has the capability to alternate the selected diversity uplink path from one loopback test to the next loop back test to ensure full testing of all RF paths.

摘要： An approach to improving TDMA system operation is disclosed wherein in-band translator components are located in the center of remote cells which would normally contain a base transceiver system (BTS). The in-band. translators employ wireless in-band signaling for downlink transmission of commands from an operation and maintenance center (OMC) and uplink transmission of status-indicating and alarm signal data. The remotely located repeaters of the present invention have frequency shift key detection and demodulation capability incorporated in the downlink path, while also incorporating FSK modulation capability into the uplink path. This allows the repeater to extract commands from the serving BTS downlink signal and act on them. It also allows for the repeater to transmit status-indicating signals and alarms to the OMC via the uplink path to the serving BTS.
