Description
Technical Field
The present invention relates to the field of communications technologies, and in particular, to an active antenna processing unit AAU, a method, an apparatus, a device, and a storage medium for switching an operating state.
Background
The great difficulty in the development of 5G is power consumption, the typical power consumption of a 5G macro station single system is 3-5 kW, which is 2-3 times that of a 4G base station, and part of the reason for the increase of the power consumption of a single 5G base station is that a Massive MIMO (multiple input multiple output) technology is introduced. The 4G base station will primarily employ 4T4R, i.e., 4 transmit antennas and 4 receive antennas, while the 5G base station will employ 64T64R, i.e., 64 transmit antennas and 64 receive antennas.
The 5G Base station master device is composed of a BBU (Building Base band Unit) and an AAU (Active Antenna Unit). The BBU is mainly responsible for baseband digital signal processing, such as FFT/IFFT, modulation/demodulation, channel coding/decoding, and the like. The AAU is mainly composed of a DAC (Digital to analog Converter), a Radio Frequency (RF) unit, a Power Amplifier (PA), an antenna, and the like, and is mainly responsible for converting a baseband Digital signal into an analog signal, modulating the analog signal into a high-Frequency RF signal, amplifying the high-Frequency RF signal to sufficient Power through the PA, and transmitting the high-Frequency RF signal through the antenna. The base station power consumption is composed of PA power consumption, RF power consumption and BBU power consumption, and the total power consumption of the base station is multiplied as the TRX link is increased. The more antenna units of Massive MIMO, each antenna unit is provided with a PA and an RF unit, the TRX link is increased, and meanwhile, the calculation power consumption of BBU is increased along with the increase of the TRX link, so the total power consumption of the base station is increased. Energy saving and consumption reduction of a 5G base station are very important works, and the AAU common transmission power needs to be reduced under the condition that the number of users or the flow needs to be reduced, and the AAU is deeply dormant or completely powered off.
The power domains of the AAU in the prior art are divided into two, as shown in fig. 1:
1) the power domain 1 comprises an interface FPGA, a main processor and an optical module, the power supply of the power domain 1 can ensure the communication between the BBU and the AAU, and the BBU can enable the AAU to be switched under each power consumption state by sending a control command remotely.
2) And the power domain 2, the power supply range intermediate frequency FPGA, the transceiving circuit and the PA circuit can switch power consumption under no-load and full-load states.
The base station is composed of complex components, wireless signals with fluctuating envelopes are processed, complex wireless environments under different scenes are faced, and factors influencing the power consumption of the base station are dynamic and diverse. Therefore, the main factors affecting the power consumption of the base station are: PA power consumption, leakage power consumption, and chip power consumption. Taking a 64TR AAU as an example, the maximum power consumption of a single AAU is greater than 1000W.
AAU power consumption can be divided into: no-load power consumption, half-load power consumption, full-load power consumption and deep sleep power consumption, wherein the power consumption of the AAU in the no-load state is 30 percent of the power consumption. Therefore, in the existing design, the power consumption of the AAU in the sleep state is expected to be larger than 100W, and the interface FPGA of the AAU needs to keep communicating with the interface FPGA of the BBU, although the AAU is completely powered off, which is the best energy-saving scheme, the BBU cannot remotely wake up the AAU in the power-off state of the AAU.
In summary, in the prior art, the active antenna processing unit AAU still needs to maintain communication with the baseband processing unit BBU in the sleep state, so that power consumption is large and an optimal energy saving effect cannot be achieved.
