Abstract

Disclosed are a method and device for triggering an aperiodic CSI triggering state. The method comprises the steps that a network device generates and sends DCI, wherein the DCI is used for triggering a first aperiodic CSI triggering state and / or a second aperiodic CSI triggering state, the first aperiodic CSI triggering state is an aperiodic CSI triggering state for beam measurement reporting, and the second aperiodic CSI triggering state is an aperiodic CSI triggering state used for CSI acquisition. According to the method and the device, the non-periodic CSI triggering state for beam measurement reporting or the non-periodic CSI triggering state for CSI acquisition is triggered through the DCI, so that decoupling of a non-periodic beam measurement reporting function and a CSI acquisition function is realized.

Description

technical field [0001] The present application relates to the field of communication technologies, and in particular to a method and device for triggering an aperiodic CSI trigger state. Background technique [0002] In the NR R15 / 16 standard, beam management and channel state information (Channel State Information, CSI) acquisition share the same configuration framework. Wherein, the network device configures CSI-MeasConfig through Radio Resource Control (RRC), and then triggers all L1 / L2 beam measurement configurations and CSI acquisition measurement-related configurations. For aperiodic CSI reporting, the network device configures CSI-AperiodicTriggerState at the RRC layer, each CSI-AperiodicTriggerState is configured with multiple CSI-AssociatedReportConfigInfo, and each CSI-AssociatedReportConfigInfo is configured with its associated CSI-ReportConfig and measurement resources. And for each CSI-AperiodicTriggerState, when the network device configures its associated CSI...
