    Abstract: Embodiments of the present invention provide a signal processing method and a terminal. The method includes: receiving a control signal. Channel state information between a coordinated base station and the terminal and between the serving base station and the terminal is determined. Information is about determined time difference or information about a phase difference of arrival between signals sent by the coordinated base station and the serving base station at the terminal according to the channel state information. Adjustment information is sent to the serving base station so that the serving base station adjusts the sending time, phase, or pre-coding manner of the signal according to the adjustment information.

    Abstract: Embodiments disclose a cell status changing method. The method includes receiving, by user equipment, a first indication sent by a master base station, where the first indication is used to indicate a status change of a first cell of the master base station or a status change of a second cell of a secondary base station; and performing activation on the first cell or the second cell according to the first indication, or performing deactivation on the first cell or the second cell according to the first indication. In embodiments, both the master base station and the secondary base station serve the UE and undergo carrier aggregation, and the UE may obtain, by using the received first indication sent by the master base station, an active state or an inactive state of a serving cell that belongs to a base station that serves the UE.

    Abstract: A core network element includes a processor, and a non-transitory memory coupled to the processor. The non-transitory memory is configured to store non-transitory instructions, and in response to being executed by the processor, cause the core network element to perform operations including generating, by a first artificial intelligence (AI) protocol layer of the core network element, an AI parameter. The first AI protocol layer of the core network element is an upper layer of a next generation application protocol (NGAP) protocol layer of the core network element. The operations further include sending the AI parameter to a first access network device, and receiving the AI data from the first access network device. The AI parameter is useable for indicating AI data that is to be obtained and an obtaining manner of the AI data.
