Apparatus and methods for envelope alignment calibration in radio frequency (RF) systems are provided. In certain embodiments, calibration is performed by providing an envelope signal with a peak along an envelope path, and by providing an RF signal with a first peak and a second peak to a power amplifier along an RF signal path. Additionally, an output of the power amplifier is observed to generate an observation signal using an observation receiver. The observation signal includes a first peak and a second peak corresponding to the first peak and the second peak of the RF signal, and a delay between the envelope signal and the RF signal is controlled based on relative size of the peaks of the observation signal to one another.

Embodiments of the present disclosure provide an information reporting method, a terminal and a network device for defining reporting rules of CSI report for the terminal which is in the DRX mode and in the inactive time. The method includes: when the terminal is in a discontinuous reception (DRX) mode, determining, according to first information, whether the terminal in an inactive time reports a channel state information (CSI) report. The first information is configured to indicate allowing the terminal in the inactive time to report the CSI report at a CSI report instant, or prohibiting the terminal in the inactive time from reporting a semi-persistent or aperiodic CSI report reported on a physical uplink shared channel (PUSCH) at the CSI report instant.
