example 1

[0076] If the reserved CSI-RS is a CSI-RS with non-zero power, the UE can determine whether the CSI-RS is punctured according to whether the detected sequence is the sequence of the CSI-RS instead of obtaining the instruction from the base station. .

example 2

[0078] If the UE is reporting CSI or beam (beam) aperiodically, when the UE finds that the normal CSI-RS with non-zero power is punctured, the following processing is performed:

[0079] (1) If the UE is configured to report a wideband report (broadband report), the UE reports an OOR (out-of-range) report in the corresponding widebandCSI / beam report (beam report), or the UE gives up reporting the wideband CSI / beam report beam.

[0080] (2) If the UE is configured to report UE selected reports (terminal selection report), the UE is reported in the subband(s) CSI / beam report of the puncture in the corresponding wideband CSI / beam and corresponding selected subbands (selected subbands) OOR report, or the UE abandons the corresponding wideband CSI / beam, and the subband(s) CSI / beam report corresponding to the puncture in selectedsubbands.

[0081] (3) If the UE is configured to report configured reports (configuration reports), the UE reports an OOR report in the subband(s) CSI / bea...

example 3

[0083] If the UE performs periodic reporting, when the UE finds that the punctured is a normal CSI-RS with non-zero power, it performs the following processing:

[0084] (1) If the UE is configured to report the wideband report, before the next effective measurement of NZP CSI-RS, the UE reports the OOR report in the corresponding widebandCSI / beam report, or the UE gives up reporting the wideband CSI / beam, or the UE reports the last valid NZP CSI-RS measurement results;

[0085] (2) If the UE is configured to report UE selected reports, before the next effective measurement of NZP CSI-RS, the UE reports OOR in the subband(s) CSI / beam report punctured in the corresponding wideband CSI / beam and corresponding selected subbands report, or the UE gives up the corresponding wideband CSI / beam report, corresponding to the punctured subband(s) CSI / beamreport in the selected subbands, or the UE reports the measurement result of the last valid NZPCSI-RS.

Abstract

Embodiments of the present invention provide a method for processing a reference signal and a user terminal, the method including: obtaining information about reference signals that are reserved; and according to the information about reference signals that are reserved, the user terminal aborts processing or reporting of reference signals Abnormal report, to avoid the problem that the UE performs channel measurement on the reserved reference signal resources, resulting in inaccurate measurement report results.

Description

technical field [0001] Embodiments of the present invention relate to the field of communication technologies, and in particular to a reference signal processing method and a user terminal. Background technique [0002] For channel measurement and tracking, the base station sends reference signals in the downlink. The UE (user terminal) measures the reference signal at the corresponding position, and reports the measurement result in a certain format, such as CQI (Channel Quality Indicator, channel quality indicator) or beam (beam) related information. Since the reference signal is triggered by base station scheduling or sent periodically in advance, the base station cannot predict the arrival of the URLLC (ultra-high reliability and ultra-low latency communication) service. When the base station needs to schedule the transmission of the URLLC service, it is likely to preempt (occupy) part of the ongoing signal transmission of the eMBB (enhanced mobile broadband) service. ...
