Embodiment 1

[0066] The wireless repeater is a same-frequency relay station that directly amplifies mobile communication signals. It does not change the frequency of the original signal, nor does it perform any processing on the information carried by the signal. While amplifying the useful signal, the wireless repeater also amplifies various noise signals in the same frequency band, and the amplified noise signal is easier to transmit uplink to the base station. When the number of repeaters installed in a cell reaches a certain number, the uplink noise brought by the repeaters will cause interference to the base station, resulting in the deterioration of the sensitivity of the base station equipment and other hazards. The greater the output power of the repeater, the smaller the number of repeaters that can be installed in one cell.

[0067] Application of wireless repeater in TD-LTE system:

[0068] Since the TD-LTE communication system works in a high-frequency band, such as 2.6GHz, i...

Abstract

The present invention discloses a repeater control method and device. The method comprises: determining whether the uplink amplification link of the repeater has a terminal access or not; and if the uplink amplification link of the repeater has a terminal access, allowing the uplink amplification link of the repeater to convert to an opening state from the closure state. The problems are solved that the power consumption is large and the uplink link interference is brought in the current communication system when the wireless repeater is used.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a repeater control method and device. Background technique [0002] Since the wireless signal attenuates with the increase of the propagation distance, the users at the edge of the cell and the users in the blind area have poor performance due to their weaker signals. In order to solve the problem of weak coverage and deep coverage, repeaters are widely used in the network to improve network coverage. [0003] Among them, the repeater is a kind of relay station that directly amplifies the radio frequency signal of the mobile communication system. It does not perform any processing on the information carried by the original signal. First of all, as a signal amplification device, the repeater is mainly composed of amplifiers and filters. In order to achieve a certain gain (generally above 60dB), the amplifier is realized by multi-stage cascading; at the same time, ...
