Description

Resource relation notification and determination methods, base station and terminal

Technical Field

The present invention relates to the field of communications applications, and in particular, to a method, a base station, and a terminal for notifying and determining a resource relationship.

Background

In the measurement connection configuration of the radio resource control (Radio Resource Control, RRC), the channel state information (Channel State Information, CSI) measurement configuration may have a plurality of measurement connections (links), where the connections (links), which may also be referred to as links, contacts, are used herein without limiting the invention; each measurement connection includes a CSI reporting (reporting) identity, a CSI resource (resource) identity, and a measurement quantity (which may be referred to as measquality) indicating channel measurements (Channel Measurement, CM) or interference measurements (Interference Measurement, IM).

CSI report setting can be divided into CSI acquisition (CSI acquisition) and beam management (beam management) reports whose content needs to be measured by the resource setting associated with them. The association between Report setting and resource setting is as follows:

each Trigger state (Trigger state) of a high-level parameter Report Trigger (Report Trigger) configuration is associated with one or more Report settings, wherein each Report setting is connected to one or more periodic (periodic), semi-persistent (semi-persistent), or aperiodic (adaptive) resources setting:

when one resource setting is connected, the resource setting is used for channel measurement (CSI acquisition) or L1-RSRP calculation (beam management);

when two resources are connected, the first is for channel measurement and the second is based on interference measurement of CSI interference measurement (CSI Interference measurement, CSI-IM) typically referred to as zero power ZP CSI-RS or interference measurement of non-zero power NZP CSI-RS.

When three resources are connected, the first is for channel measurement (channel measrement, CM), the second is CSI-IM based IM, and the third is NZP CSI-RS based IM.

When one resource setting of the Report setting connection contains a plurality of aperiodic resource sets (resource sets), a bitmap (bitmap) configured by RRC is used to select the resource set used in each resource setting when trigger is triggered by a trigger. For resource setting for CSI acquisition, only one resource set is selected.

When one report setting connects two or three resource settings, there is no solution yet how to determine the association relationship of multiple resources in the resource set selected in each resource setting.
