摘要： A system calibrates the gain of a repeater by determining a value based on the difference between respective amplitude measurements made while the repeater is transmitting and while it is not. The value is compared to threshold data in order to determine whether repeater attenuation should be incrementally adjusted.

摘要： A repeater system includes a first repeater device that receives a first beam of radio frequency (RF) signal from a first network node and a second repeater device that receives a second beam of RF signal from the first network node. The first repeater device controls the second repeater device to provide the first beam of RF signal and the second beam of RF signal to a second network node and select a plurality of signal parameters at the first repeater device and the second repeater device for the first beam of RF signal and the second beam of RF signal respectively, based on a plurality of measurements. The first repeater device further controls the second repeater device to establish an additional link with the second repeater device to create an additional dimension in a MIMO channel between the first network node and the second network node.

摘要： Provided is a wireless communication method and related apparatus. In the method, a repeater reports a capability of the repeater to the base station for the base station to determine a repeater gain, and the repeater utilizes the repeater gain designated by the base station to amplify a received signal transmitted to or from the at least one user equipment served by the repeater. With this method, multipath or multi-user interference introduced by the repeater to the mobile network can be minimized. In addition, the transmit power of the user equipment served by the repeater can be effectively reduced.

摘要： A technology is described for a repeater. A repeater can comprise a first port; a second port; a first-direction amplification and filtering path coupled between the first port and the second port; a multiplexer coupled between: the first-direction amplification and filtering path; and the second port; and a power amplifier (PA) coupled between the first port and the multiplexer. The repeater can further comprise an adjustable matching network coupled between the PA and the multiplexer, wherein the adjustable matching network is actively adjusted to match an impedance of an output of the PA at a selected channel over a frequency range for a first-direction signal with an impedance of an input of the multiplexer over the selected channel over the frequency range for a first-direction signal.

摘要： A method includes inserting a first reference signal and a plurality of bit fields on a first channel, to produce a first signal, where the plurality of bit fields includes a first bit field indicating whether a second reference signal is transmitted on a second channel, a second bit field indicating whether the first reference signal has the same precoding as the second reference signal, a third bit field indicating whether precoding of the first reference signal is similar to precoding of the second reference signal, or a fourth bit field indicating transmission precoding differences between the first reference signal and the second reference signal. The method also includes performing precoding on the first signal, to produce a first transmission signal, performing precoding on the second channel, to produce a second transmission signal, transmitting, to a receiver, the first transmission signal and transmitting, to the receiver, the second transmission signal.

摘要： The methods and systems for amplify-and-forward (in-band) relaying relate to beamforming techniques including receive and transmit beamforming for reducing self-interference, and improving Signal-to-Noise Ratio (SNR), or Signal to Interference plus Noise Ratio (SINR), of an incoming signal (to be relayed). The incoming signal is amplified and retransmitted simultaneously with the incoming signal, and over the same frequency band as that of an incoming signal.

摘要： An interference cancellation repeater includes: a first transmission/reception processing unit configured to convert a radio frequency (RF) input signal input via a link antenna communicatively coupled to a base station into a digital input signal; an interference canceller configured to cancel an interference signal from the digital input signal and to output an interference canceled signal; a second transmission/reception processing unit configured to convert the interference canceled signal into an RF output signal and to amplify the RF output signal; and a gain controller configured to detect a gain change of the interference cancellation repeater based on the interference canceled signal and to change a current gain of the interference cancellation repeater to a target gain by adjusting intensity of at least one of the RF input signal, the interference canceled signal, and the RF output signal when the gain change of the interference cancellation repeater is detected.

摘要： Certain features relate to operating a distributed antenna system or repeater system communicating frequency-division duplexing (“FDD”) signals in a time-division duplexing (“TDD”) mode. A TDD mode scheduler is configured for monitoring a downlink communications channel for the start of a downlink frame, sub-frame, or resource slot. Based on the start of a downlink frame, sub-frame, or resource slot, the TDD mode scheduler can identify a TDD transmission time-slot. The TDD mode scheduler can schedule high-powered downlink sub-frames during the TDD transmission time-slots where higher power output may be desirable. Based on the indication of the TDD transmission time-slot, a transmit/receive controller can increase the gain of the downlink communication and reduce the gain of the uplink communication.
