Abstract: Embodiments of the present invention provide a method, an apparatus, and a system for handover processing. The method includes: receiving a handover request sent by a UE for handover to a micro base station; and sending instruction information to the UE according to a preset rule and the handover request, so as to instruct the UE to send start information, where the start information is used to instruct the micro base station to start an interference coordination mode used to enable the micro base station to mute preset time-frequency resources and corresponding to the start information. This prevents formation of a victim UE and greatly mitigates impacts caused by a coverage hole.

Abstract: A communication method includes determining a reserved carrier in a bandwidth part (BWP) based on a tone reservation (TR) pattern and a first correspondence. The TR pattern includes a set of subcarriers used as reserved carriers. The first correspondence is a correspondence between an index that is of a subcarrier in the TR pattern and that is in the TR pattern and an index that is of the subcarrier in the TR pattern and that is based on a first common resource block (CRB). The communication method further includes outputting a time domain signal based on the reserved carrier in the BWP.

Abstract: This application provides a scheduling method, a scheduling system, and a scheduling apparatus. After obtaining a reward feedback for a previous scheduling decision sent by a terminal device, a scheduler may send, in N time units after the reward feedback is received, a current scheduling decision calculated based on the reward feedback, where N>1 and N is an integer, so that sufficient time can be left for the scheduler to calculate and code the scheduling decision, thereby effectively resolve a problem that a scheduling procedure mismatches and conflicts with an over-the-air time sequence when the scheduler cannot obtain a reward of the previous scheduling decision in time.
