Technology for a repeater is disclosed. The repeater can include a signal path configured to carry a signal having a selected radio frequency (RF) bandwidth on an RF carrier at a selected frequency. The signal path can include an intermediate frequency (IF) filter block operable for down-conversion of the RF carrier to an IF carrier to enable the selected RF bandwidth of the signal to be bandpass filtered at an IF filter bandwidth having an IF passband frequency range and the IF passband frequency range of the IF filter bandwidth is greater than the selected RF bandwidth. The down-conversion to the IF carrier can provide increased crossover attenuation or midband isolation of the RF carrier for the repeater.

A technology is described for adjusting repeater gain based on user equipment need. A downlink path of the repeater can be deactivated. A deactivated throughput value can be received from the UE for data received at the UE in a selected time period. The downlink amplification path of the repeater can be activated. An activated throughput value for data received at the UE in the selected time period can be received from the UE. A difference can be determined between the deactivated throughput value and the activated throughput value. A repeater gain value can be reduced or bypassed when the deactivated throughput value is greater than the activated throughput value by a selected threshold value.

A wireless repeater receives an RF signal at a first meta-surface antenna. A signal relay chain amplifies a received RF signal from the first meta-surface antenna into a transmit RF signal that is transmitted by a second meta-surface antenna. Alternatively, the signal relay chain receives the RF signal at a reception port of the first meta-surface antenna, which may include a transmit port for receiving the transmit RF signal.

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.

Technology for a repeater is disclosed. The repeater can include a first port and a second port. The repeater can include a transmitter communicatively coupled to the first port and a receiver communicatively coupled to the second port. The transmitter can transmit a path loss signal. The receiver can receive the path loss signal transmitted by the transmitter. The repeater can include a controller. The controller can identify a first power level of the signal transmitted from the transmitter. The controller can identify a second power level of the signal received at the receiver. The controller can determine an antenna feedback path loss of the repeater based on the first power level and the second power level. The controller can set a maximum gain level for the repeater based on the antenna feedback path loss to avoid an oscillation in the repeater.

A technology is described for a time division duplex (TDD) repeater with network protection. The TDD repeater can comprise a first port, a second port, and one or more amplification paths coupled between the first port and the second port. The TDD repeater can comprise a signal detector configured to measure a received signal power for a downlink (DL) signal in a first set of one or more TDD DL subframes. The TDD repeater can be further configured to adjust an uplink (UL) noise power or gain of the one or more amplification paths based on the received signal power for the DL signal in the first set of the one or more TDD DL subframes.

The advantageously leverages the use of a digital signal processing (DSP) circuitry, which may decode the data and control information. The control information may be used to control IDR behavior (e.g., in the uplink and/or downlink directions) and to enhance its characteristics.
