Abstract
The invention provides a configuration method of channel state information resources and a network unit, and belongs to the technical field of wireless communication. 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 configuring the measurement resources used for reporting the channel state information or associated with the user equipment in the discontinuous reception mode outside the activation period and/or the drx-onDurationTimer running period through the first signal indication and/or the predefined and/or high layer signaling. The technical scheme of the invention aims at the connected user equipment with the DRX started, and can trigger the connected user equipment to report the channel state information in the activation period and/or the DRX on DurationTimer running period.
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 reporting types, namely periodic, semi-periodic, and aperiodic. Wherein, the periodic 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 by high-level signaling, and reported on PUCCH (physical uplink shared channel) resources, or triggered by 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, the base station cannot frequently acquire the channel state information due to the reduction of CSI reporting opportunities, and especially for the first scheduling opportunities in the DRX-onDurationTimer, the channel state information is difficult to obtain, which may cause a large impact on the base station scheduling of the ue. 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.
