Abstract: A handover processing method, apparatus, and system include: receiving a first handover trigger message sent by a first network element node; and sending a second handover trigger message to a second network element node according to the first handover trigger message, so that the second network element node hands over user equipment UE from the first network element node to the second network element node according to the second handover trigger message. Handover between small cells or between a small cell and a macro cell is implemented, and because a controller is used to perform handover, a handover delay is effectively reduced, and network performance is improved.

Abstract: The disclosure provides example communication methods and apparatuses. One example method includes that a network device sends a first message to a terminal apparatus, where the first message indicates the terminal apparatus to perform BWP switching. In addition, the network device send scheduling information to the terminal apparatus within first duration after sending the first message, where the scheduling information is used to schedule data of the terminal apparatus. According to the foregoing method, the network device can continue to schedule uplink and downlink data of the terminal apparatus within the first duration after sending IMP switching signaling to the terminal apparatus.

Abstract: Embodiments of the present invention relate to a channel estimation method, a base station, user equipment UE, and a system. The method includes: setting up, by a base station, a connection to user equipment UE; and sending, to the UE, notification information indicating that the UE is in a radio remote scenario, where the notification information is used to instruct the UE to perform channel estimation by using a channel estimation algorithm applicable to the radio remote scenario, and the channel estimation algorithm is used to perform channel estimation on a signal that is obtained after downlink signals from multiple radio remote units RRUs are superposed. The UE can perform channel estimation by using the appropriate channel estimation algorithm, to effectively improve accuracy of the channel estimation, thereby effectively improving a downlink data throughput of the UE.

Abstract: This application provides an inter-frequency measurement resource and/or time determining method and an apparatus. When a length of each idle time domain resource is greater than or equal to a first threshold, or when a cycle of discontinuous reception configured by a network device is greater than or equal to a second threshold, a terminal device uses a part of the idle time domain resource as a first resource that is in the idle time domain resource and that can be used to perform inter-frequency measurement. The terminal device determines, based on the first resource in each idle time domain resource, a resource and/or time used to perform the inter-frequency measurement.
