Abstract: Embodiments of the present invention provide a channel-state information process processing method, a network device, and a user equipment, where the channel-state information process processing method includes: after receiving a first channel-state information CSI request sent by a first network device, if CSI corresponding to multiple aperiodic CSI processes has not been reported by a user equipment, dropping CSI corresponding to a part of aperiodic CSI processes among the multiple aperiodic CSI processes, where each CSI process is associated with a channel measurement resource and an interference measurement resource. A problem existing after a CoMP technology is introduced can be solved that the UE cannot implement processing of multiple CSI processes.

Abstract: This application discloses a network operation, administration, and maintenance (OAM) method, an apparatus, and a system. The method includes: receiving a fault alarm message sent by an MP, where the fault alarm message includes fault information; determining according to the fault alarm message, a first maintenance set to which the MP belongs, where the first maintenance set includes MPs using a first OAM technology; querying an OAM database, to obtain a second maintenance set interacting with the first maintenance set, where the second maintenance set includes MPs using a second OAM technology; and sending a fault notification message to all MPs in the second maintenance set or an MP that is determined according to a policy in the second maintenance set. Therefore, a related fault alarm may be centrally notified on a management plane, and is decoupled from a specific OAM technology, thereby greatly reducing an implementation difficulty.
