specific Embodiment 1

[0066] The base station configures a sidechain CSI report set for the UE. If it is periodic CSI reporting or semi-persistent CSI reporting, the sidechain CSI reporting set is configured with PUCCH resources, and the periodic CSI or semi-persistent CSI is reported based on the PUCCH resources.

[0067] When the base station configures the sidechain CSI report set, multiple sidechain CSI reports may use the same PUCCH resource, or may use different PUCCH resources. Wherein, each CSI report does not include the channel measurement reference signal and the interference measurement reference signal, but may include the parameter reportConfigType and the parameter reportQuantity.

[0068] Further, when configuring the CSI report set, the base station may add multiple target identifiers, and may also add multiple frequency identifiers. Wherein, the frequency identifier is associated with the target identifier, and the frequency identifier is used to indicate which target identifiers...

specific Embodiment 2

[0077] The base station configures the sidechain CSI report set for the UE. If it is aperiodic CSI reporting, the sidechain CSI reporting set is configured with PUSCH resources, that is, the aperiodic CSI is reported based on the PUSCH resources.

[0078] In a specific implementation, each aperiodic trigger state (CSI-AperiodicTriggerState) includes multiple CSI reports (the parameter is CSI-AssociatedReportConfigInfo). If each CSI report in the multiple CSI reports is used to send the UE to send a sidechain CSI report, the CSI report may not contain reference signal information, and a target identifier may be added, so that the DCI-triggered CSI report is located in the PUSCH resource Aperiodic CSI can include at least one unicast sidechain CSI. In addition, each CSI report may also add a frequency identifier associated with the target identifier.

[0079] If the base station needs the UE to report multiple unicast sidechain CSIs, the trigger state parameter may include mul...

Abstract

A side chain CSI reporting and configuration method and device, storage medium, terminal, and base station, the reporting method comprising: receiving side chain CSI reporting configuration information, the side chain CSI reporting configuration information including at least one target associated with the CSI report identification; based on the side chain CSI report configuration information, determine the side chain CSI associated with the target identification; report the side chain CSI. The embodiment of the present invention provides a feasible solution for side chain CSI reporting.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular, to a method and device for reporting and configuring side chain CSI, a storage medium, a terminal, and a base station. Background technique [0002] In 2018, the 80th plenary session of the 3rd Generation Partnership Project (3GPP) approved the 5G New Radio (NR) research project on Vehicle to Everything (V2X). V2X refers to the use of wireless communication, sensor detection and other technologies to collect road traffic environment information, through real-time, efficient, two-way information exchange and sharing between vehicles, vehicles and people, and vehicles and infrastructure. Pedestrians provide reliable traffic information, thereby effectively improving road system safety and improving the traffic environment. [0003] V2X communication includes vehicle to vehicle (V2V) communication, vehicle to roadside infrastructure (V2I) communication, vehicle t...
