Embodiment 1

[0106] According to an aspect of the embodiments of the present invention, a control method of a time division duplex repeater is provided. First, the method determines the frequency band that can be synchronized with the base station and the uplink and downlink time slots corresponding to the frequency band, and from the frequency band that can be synchronized with the base station. The frequency band with the best signal quality is selected from the frequency bands synchronized by the base station; then, in the uplink and downlink time slots, the signal of the corresponding time slot is received, and the signal is received in the channel corresponding to the frequency band with the best signal quality processing; finally, sending the processed signal.

[0107] Such as figure 2 As shown, the control method includes:

[0108] Step S21. Determine the frequency bands that can be synchronized with the base station and the uplink and downlink time slots corresponding to the freq...

Embodiment 2

[0149] According to another aspect of the embodiment of the present invention, a control device for a time division duplex repeater is also provided, such as image 3 As shown, the control device 300 includes:

[0150] The control synchronization module 301 is used to determine the frequency band that can be synchronized with the base station and the uplink and downlink time slots corresponding to the frequency band, and select the frequency band with the best signal quality from the frequency bands that can be synchronized with the base station;

[0151] The processing module 303 is configured to receive signals of corresponding time slots in the uplink and downlink time slots, and process the signals in the channel corresponding to the frequency band with the best signal quality;

[0152] The sending module 305 is configured to send the processed signal.

[0153] Optionally, the control synchronization module 301 is further used for:

[0154] Opening the nth channel, and j...

Embodiment 3

[0184] According to another aspect of the embodiments of the present invention, a time-division duplex repeater is also provided, including the control device for the above-mentioned time-division duplex repeater.

Abstract

The present invention provides a method and a device for controlling a time-division duplex repeater, and the time-division duplex repeater. The method comprises the steps of determining frequency bands synchronized with a base station, and uplink time slots and downlink time slots corresponding to the frequency bands; selecting one frequency band best in signal quality out of all frequency bands synchronized with the base station; receiving the signals of corresponding time slots during the uplink and downlink time slots; processing the signals within a channel corresponding to the above selected frequency band best in signal quality; and sending out the processed signals. According to the technical scheme of the invention, signals are transmitted within the selected frequency band best in signal quality through the hand-over selection among a plurality of frequency bands. Compared with the prior art, the defect that only one frequency band among the plurality of frequency bands is available in the prior art can be overcome.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a control method and a device for a time-division duplex repeater and a time-division duplex repeater. Background technique [0002] The pace of mobile communication development is accelerating, and the number of mobile communication users is also increasing rapidly. At the same time, with people's excessive worries about radiation and the increasing difficulty of property coordination, construction costs are increasing, making the construction of mobile communication base stations more and more difficult, and it is almost impossible to achieve seamless and continuous coverage of the network purely relying on base station equipment , so in this context the researchers proposed a repeater solution. [0003] The repeater is located in the coverage edge area of ​​the base station, extending to the coverage of the base station, and the composition of the repeater includ...
