Embodiments of this disclosure provide a power adjustment method, apparatus, and system. A first access network device may obtain a power back-off value at a first moment, and compare the power back-off value at the first moment with a power back-off value at a second moment. The second moment is earlier than the first moment. When a difference between the power back-off value at the second moment and the power back-off value at the first moment is greater than or equal to a first threshold, the first access network device adjusts an output power based on the power back-off value at the first moment.

Certain aspects of the present disclosure provide techniques for aperiodic channel state information (A-CSI) transmission with slot aggregation. A method that may be performed by a user equipment (UE) includes receiving a grant scheduling a slot aggregated transmission in a plurality of aggregated slots and triggering an aperiodic channel state information (A-CSI) transmission in one of the plurality of aggregated slots. The method includes determining one or more of the plurality of aggregated slots to transmit the A-CSI transmission. The method includes transmitting the A-CSI transmission in the determined one or more of the plurality of aggregated slots.

The method includes: receiving first Downlink Control Information (DCI), where the first DCI is DCI that is not used for scheduling data, and the first DCI is used to indicate a first cell of the terminal to switch to or activate a target power saving mode.

This application provides a DAI counting method, a DAI counting control method, a terminal, and a network device. The method includes: in a case that physical downlink control channel PDCCH repetition is configured, incrementing a DAI count at a reference PDCCH monitoring occasion.

The embodiments of the present application relate to the technical field of wireless communications, and provide a device-to-device relay processing method, device and apparatus, and a storage medium, which are used for implementing an activation or deactivation function of the device-to-device relay. Said method comprises: according to channel quality information of a direct link between a first device and at least two second devices, the first device determining a processing manner of the first device for a device-to-device relay function, the processing manner comprising activating the device-to-device relay function or deactivating the device-to-device relay function.

This disclosure provides systems, methods and apparatus for aperiodic measurement configurations. In one aspect, delaying transitioning of a secondary cell group (SCG) to an active state until a next synchronization signal block (SSB) or periodic reference signal may result in an excessive delay in obtaining network resources of the SCG. Some aspects described herein enable a base station (BS) to transmit signaling using a master cell group (MCG) cell to schedule resources for an aperiodic reference signal transmission and measurement using the SCG. For example, the BS may transmit signaling to a user equipment (UE) to identify a reference signal resource for an aperiodic reference signal transmission and measurement. In this case, the BS may transmit the aperiodic reference signal using an SCG cell, and the UE may measure the aperiodic reference signal and provide a report identifying the measurement of the aperiodic reference signal.

Certain aspects of the present disclosure provide techniques for low complexity physical downlink channel. A method that may be performed by a user equipment (UE) includes determining one or more policies for monitoring one or more physical downlink control channels (PDCCHs) within one or more bandwidth parts (BWPs) for a first type of UE, wherein the one or more policies for the first type of UE are different from a set of policies for a second type of UE; and monitoring for signals from a network entity via the one or more PDCCHs according to the determined policies.

Embodiments of this application provide a communication method, apparatus, and system. The method includes: A network device sends first signaling to a terminal device on a downlink primary component carrier, where the first signaling includes configuration information of a secondary cell; the network device sends second signaling to the terminal device; and the network device determines, based on a channel state information CSI report and/or feedback signaling received from the terminal device, that the terminal device successfully activates the secondary cell.
