Embodiment 1

[0030] An embodiment of the present invention provides a method for relocating symbols in a radio frame, which is applied to a base station. The functions realized by the method for relocating symbols in wireless frames in this embodiment can be realized by calling program codes by the processor in the base station, and of course the program codes can be stored in computer storage media. It can be seen that the base station includes at least a processor and a storage medium .

[0031] For the convenience of understanding, before explaining the symbol relocation method in the radio frame of the embodiment of the present invention, the subframe and symbol service status in the long term evolution system (Long Term Evolution, LTE) are described here.

[0032] Such as figure 1 As shown, it is an LTE subframe and OFDM symbol service state diagram. One radio frame in an LTE signal includes 10 subframes, and each subframe is composed of 14 Orthogonal Frequency Division Multiplexing ...

Embodiment 2

[0053] An embodiment of the present invention provides a method for relocating symbols in a radio frame, which is applied to a base station. The functions realized by the method for relocating symbols in wireless frames in this embodiment can be realized by calling program codes by the processor in the base station, and of course the program codes can be stored in computer storage media. It can be seen that the base station includes at least a processor and a storage medium .

[0054] Figure 4 It is a schematic diagram of the implementation flow of the method for relocating symbols in the wireless frame in Embodiment 2 of the present invention, as shown in Figure 4 As shown, the method includes the following steps:

[0055] Step S401, the base station determines the current power amplifier occupancy rate of the corresponding symbol according to the ratio between the current output power of the power amplifier at the time corresponding to each symbol in the radio frame and ...

Embodiment 3

[0110] The embodiment of the present invention provides a method for relocating symbols in a wireless frame. Based on the principle of DTX energy saving according to the characteristics of power amplifier devices, the provided relocation method is a control strategy for intelligent symbol closing based on an improved Q-learning algorithm. Not only It can improve the efficiency of symbol relocation, make the matching degree as high as possible after relocation, and achieve the best energy-saving state on the basis of not increasing the system delay as much as possible, so as to maintain the stability of the network and the interests of operators. This method is not only applicable to the existing LTE system, but also applicable to the fifth generation new radio (5th Generation New Radio, 5G NR) system.

[0111] The communication system business generally obeys the Poisson distribution, but when the business volume rises or falls like a cliff, the system often cannot predict the ...

Abstract

The embodiment of the invention provides a method and a device for moving symbols in a radio frame. The method comprises the steps that a base station determines the current power amplifier occupancyrate of a corresponding symbol according to the ratio of the current output power of a power amplifier at a moment corresponding to each symbol in the radio frame to a preset compression value; determining a symbol to be moved from the symbols in the radio frame according to the current power amplifier occupancy rates of the at least two symbols; determining a target relocation symbol according toa preset algorithm; and moving a first power amplifier occupancy rate to the target moving symbol, wherein the first power amplifier occupancy rate is the current power amplifier occupancy rate of the symbol to be moved.

Description

technical field [0001] The present invention relates to the technical field of communication, and relates to but not limited to a method and device for relocating symbols in a wireless frame. Background technique [0002] During the communication process, the mobile user actually only transmits services part of the time, and does not transmit messages most of the time. For the symbols (Symbol) in any subframe (Sub Frame) in the radio frame, valid information is not filled at any moment. If all the information in these symbols is transmitted to the network, it will not only cause waste of system resources, but also aggravate the interference in the system. [0003] At present, when transmitting services, the system uses an encoder to detect a service gap, and does not send information during the gap period, which is the so-called Discontinuous Transmission (DTX). Therefore, in the current communication system, when the traffic volume is the highest, the power amplifiers at ...
