Abstract
Description
Methods, apparatus, devices and storage media for transmitting auxiliary information Technical Field
[0001] This disclosure relates to the field of communication technology, and in particular to methods, apparatus, devices and storage media for transmitting auxiliary information. Background Technology
[0002] Terminal power back-off is a technique commonly used in the radio frequency field, designed to improve the linearity of power amplifiers, i.e., transmitters.
[0003] For example, in one instance, by shifting the input power of the terminal's power amplifier back by 6-10 dB from the 1 dB compression point, the power amplifier operates at a level much lower than the 1 dB compression point, thus moving away from the saturation region and into the linear operating region. This significantly improves the third-order intermodulation distortion of the power amplifier; typically, a 1 dB reduction in fundamental power results in a 2 dB improvement in third-order intermodulation distortion.
[0004] However, power backoff by the terminal will limit its maximum transmit power, thus affecting uplink coverage. Furthermore, significant power backoff will also reduce the terminal's transmit efficiency, impacting uplink signal transmission.

[0159] Figure 2 is an interactive schematic diagram of a communication method according to an embodiment of the present disclosure. As shown in Figure 2, this embodiment of the present disclosure relates to a communication method, which includes:
[0160] In step S2101, network device 102 sends first instruction information to terminal 101.
[0161] In some embodiments, the first indication information is used to instruct the terminal 101 to send auxiliary information to the network device 102.
[0162] In step S2102, terminal 101 determines the waveform and modulation method.
[0163] In some embodiments, terminal 101 determines the waveform and modulation method according to the protocol.
[0164] In some embodiments, the waveform and modulation scheme correspond to EVM information.
[0165] In some embodiments, the waveform and modulation scheme correspond to MPR information.
[0166] In some embodiments, different EVM information corresponds to different waveforms and different modulation schemes.
[0167] In some embodiments, different MPR information corresponds to different waveforms and different modulation schemes.
[0168] In step S2103, terminal 101 sends auxiliary information to network device 102.
[0169] In some embodiments, auxiliary information is used to assist network device 102 in performing linear compensation on terminal 101.
[0170] In some embodiments, linear compensation of terminal 101 can be replaced by linear compensation of the transmitter of terminal 101.
[0171] In some embodiments, linear compensation of terminal 101 can be replaced by linear compensation of the uplink signal of terminal 101.
[0172] In some embodiments, the auxiliary information includes at least one of the following:
[0173] Nonlinear performance parameters of the terminal transmitter;
[0174] At least one EVM piece of information;
[0175] At least one MPR message;
[0176] PA type.
[0177] In some embodiments, the transmitter nonlinear performance parameters include at least one of the following:
[0178] 1dB compression point (P1dB);
[0179] Output the third-order intermodulation intercept point (OIP3).
[0180] In some embodiments, the 1dB compression point (P1dB) is the output power value at a power gain of G1 on the input-output power relationship curve, where G1 = G2 - 1dB and G2 is the linear gain on the input-output power relationship curve.
[0181] The transmitter corresponds to a linear dynamic range, within which the amplifier's output power increases linearly with the input power. The ratio of output power to input power is the power gain. As the input power continues to increase, the amplifier enters the nonlinear region, and its output power no longer increases linearly with the input power.
[0182] In some embodiments, the output third-order intermodulation intercept (OIP3) and the input third-order intermodulation intercept (IIP3) are used to measure the linearity of the RF device. On the input power versus output power graph, the third-order intermodulation intercept (TOI) point is where the linearly amplified signal on a given input curve intersects with the third-order nonlinear product. For every 1 dB increase in power, the third-order nonlinear product (IM3) increases by 3 dB; therefore, the 1:1 linearly amplified signal will eventually intersect the IM3 curve. The input power at the third-order intermodulation intercept (TOI) point is the input third-order intermodulation intercept (IIP3), and the output power at the third-order intermodulation intercept (TOI) point is the output third-order intermodulation intercept (OIP3).
