14 Claims

1. A dynamic Peripheral Component Interconnect Express (PCIe) speed-adjusting method, applied to a wireless device, comprising:

determining, by the wireless device, whether to change from a current PCIe speed to a target PCIe speed based on at least one of a noise level threshold, a signal to noise ratio (SNR) threshold and a current data rate requirement;

wherein the determining, by the wireless device, whether to change from the current PCIe speed to the target PCIe speed based on at least one of the noise level threshold, the signal to noise ratio (SNR) threshold and the current data rate requirement, comprising:

determining, by the wireless device, whether a first noise level corresponding to the current PCIe speed is higher than the noise level threshold;

selecting, by the wireless device, the target PCIe speed from at least one candidate PCIe speed in response to the first noise level being higher than the noise level threshold;

determining, by the wireless device, whether a second noise level corresponding to the target PCIe speed is higher than the noise level threshold; and

determining, by the wireless device, whether an SNR corresponding to the target PCIe speed is higher than the SNR threshold in response to the second noise level being higher than the noise level threshold.
