The configuration method of the channel state information resource is applied to network side equipment, and the method comprises the following steps: transmitting a first signal; and the UE in the discontinuous reception mode is indicated and/or configured by the first signal and/or predefined and/or high-layer signaling to perform measurement resources used for or associated with channel state information reporting in an active period and/or outside the active period and/or within a drx-onDurationTimer and/or outside the drx-onDurationTimer.

Description
Technical Field
The present invention relates to the field of wireless communication technologies, and in particular, to a method for configuring channel state information resources and a network unit.
Background
In NR (new air interface), CSI (channel state information) reporting may have three types of periodic, semi-periodic, and aperiodic. Wherein, the period CSI is reported on PUCCH (physical uplink control channel) resources through high-level signaling configuration and triggering; the semi-persistent CSI reporting can be configured and triggered through high-level signaling, and reported on PUCCH (physical uplink shared channel) resources, or triggered through DCI (downlink control information) and reported on PUSCH (physical uplink shared channel) resources; the aperiodic CSI reporting is carried out on the PUSCH resource through high-level signaling configuration and DCI triggering. For each CSI reporting type, the high-level signaling configures each corresponding measurement signal, measurement content and reporting resource for the UE.
When the configuration of DRX (discontinuous reception) is turned on, a protocol restricts the ue to report CSI only during an active period or a DRX on duration timer (discontinuous reception duration timer) running time. Different CSI reports have their periods or trigger conditions, and due to the limitation of the reporting time window, a CSI-RS (channel state information reference signal) or SSB (synchronization signal block) resource that needs to be measured or a PUCCH/PUSCH resource that needs to be reported may not occur in the active period or DRX-onDurationTimer, so that the chance of reporting CSI by the user equipment that has turned on DRX is greatly reduced. Therefore, for the connected ue that starts DRX, because CSI reporting opportunities are reduced, the base station cannot frequently acquire the channel state information, and especially the channel state information of the first scheduling opportunities in the DRX-onDurationTimer is difficult to acquire, which may cause a large impact on the ue scheduled by the base station. When the channel status changes rapidly, the scheduling accuracy of the base station for the user equipment may be reduced. If the channel state is poor, the base station schedules the ue according to a higher MCS (modulation and coding scheme), which may result in that the ue cannot decode or loses packets. If the channel state is good, the base station schedules the user equipment according to a low MCS, which may cause a decrease in throughput.
