Problems solved by technology

[0004] In the above method, when the interference signal is too large, the uplink of the base station equipment is easy to form nonlinearity, and even the A / D is directly saturated to cause blocking
For example, when the blocking value of the uplink is -30dBm, when the interference signal is greater than -30dBm, it will cause A / D saturation, so that the IoT function is no longer applicable

Embodiment 1

[0037] Aiming at the problems existing in the prior art, Embodiment 1 of the present invention provides a method for IOT data output, which is applied to the RRU (Radio Remote Unit, radio remote unit) of the base station equipment, to image 3 It is a schematic diagram of an application scenario of an embodiment of the present invention. exist image 3 In the above, the uplink includes PGC (Phase Generated Carrier, phase carrier), A / D (analog / digital converter) and AGC (Auto Gain Control, automatic gain control) as an example. For the uplink Other parts will not be described in detail in the embodiment of the present invention. Among them, PGC is used to attenuate the interference signal according to the current PGC adjustment value, A / D is used to convert the signal after attenuation processing from analog to digital, and AGC is used to convert the converted signal according to the current AGC adjustment value. Do enhancements.

Embodiment 2

[0059] Based on the same inventive concept as the above method, an embodiment of the present invention also provides a base station device, such as Figure 5 As shown, the base station equipment specifically includes:

[0060] Determining module 11, used to determine that the phase carrier PGC adjustment compensation strategy is currently met;

[0061] Judging module 12, for judging whether the current PGC adjustment value reaches the maximum PGC adjustment value;

[0062] The processing module 13 is used to increase the PGC adjustment value when the judgment result is that the maximum PGC adjustment value has not been reached, use the increased PGC adjustment value to attenuate the signal, and use the increased PGC adjustment value to determine the PGC compensation value, And use the PGC compensation value to perform compensation processing on the signal, and use the compensated signal to determine the IOT data raised by the interference noise, and output the IOT data.

Abstract

The invention discloses an IOT (Interference Over Thermal) data output method and device. The IOT data output method includes: a base station device determines a compensation strategy satisfying PGC (Phase Generated Carrier) adjustment currently; the base station device judges whether a current PGC adjustment value reaches the maximum PGC adjustment value; if not, the base station device increases the PGC adjustment value and conducts signal attenuation processing by aid of the increased PGC adjustment value; the base station device determines a PGC compensation value by aid of the increased PGC adjustment value, and conduct signal compensation processing by aid of the PGC compensation value; the base station device determines IOT data by aid of the compensated signals and outputs the IOT data. The IOT data output method and device avoid blocking caused by overlarge interference signals and enlarge the range of interference signal detection strength. When an AGC (Auto Gain Control) adjustment value reaches the maximum AGC adjustment value, uplink link attenuation is increased directly through the PGC adjustment value, and accordingly the signal level and power entering an A / D (Analog / Digital) conversion circuit are reduced.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method and device for IOT data output. Background technique [0002] The interval between the 1860-1880MHz frequency band in the FDD (Frequency Division Duplex, frequency division duplex) system and the 1885-1915MHz frequency band in the TDD (Time Division Duplexing, time division duplex) system is very small, which easily causes interference. When the frequency bands of 2300-2390MHz and 2555-2655MHz are allocated to multiple operators for TDD-LTE (Long Term Evolution, long-term evolution) construction, if the clocks of the operators cannot be strictly synchronized, or the uplink and downlink ratios are not uniform, It is also easy to cause interference. In order to find and solve the interference problem in time, the base station equipment outputs IOT (Interference Over Thermal, interference noise rise) data, so as to find and solve the interference problem thr...
