Description

Method for reporting channel state information and network element
Technical Field
The present invention relates to the field of wireless communications technologies, and in particular, to a method and a network element for reporting channel state information.
Background
The CSI (channel state information) reporting in the NR (new air interface) may have three reporting types, i.e., periodic, semi-persistent, and aperiodic. Wherein, the periodic CSI reporting is configured and triggered through a high-layer signaling, and reported on PUCCH (physical uplink control channel) resources; semi-persistent CSI reporting can be configured and triggered through high-level signaling, can be reported on PUCCH resources, or can be triggered through DCI (downlink control information), and can be reported on PUSCH (physical uplink shared channel) resources; reporting the apidic CSI is performed through high-level signaling configuration, DCI triggering and reporting on PUCCH resources. For each CSI reporting type, the higher layer signaling configures each reporting corresponding measurement signal, measured content, and reported resource for the ue.
If CSI is reported on PUCCH, the higher layer signaling configures its PUCCH resources for each report, including PUCCH format, time domain period and offset value, frequency domain resources, code domain resources, and so on. If CSI is reported on PUSCH, DCI may indicate time-frequency domain resources used by PUSCH, etc.
For RRC (radio resource control) connected UEs, except for configuring its corresponding PUCCH resource for each CSI report, the base station may configure UCI (uplink control information) for feedback for the UE, including SR (uplink scheduling request), HARQ-ACK (hybrid automatic repeat request acknowledgement), PUCCH resource for CSI. The higher layer signaling configures a maximum of 4 PUCCH resource sets for the UE, including a plurality of PUCCH resources in each resource set. The higher layer signaling configures the frequency domain resource location, time domain symbol length, PUCCH format, cyclic shift, etc. of each PUCCH resource. If the UE needs to transmit N UCI And the UE implicitly selects the used PUCCH resource set according to the UCI information of the bits. If N UCI If less than or equal to 2, the UE uses the first PUCCH resource set, if 2 < N UCI ≤N 2 The UE uses the second PUCCH resource set if N 2 ＜N UCI ≤N 3 The UE uses the third PUCCH resource set if N 3 ≤N UCI And 1706, the UE uses a fourth set of PUCCH resources. Wherein N is 2 And N 3 Configured by higher layer signaling. Further, the DCI may instruct the UE to use a specific one of the PUCCH resource sets for transmission of UCI.
The protocol limits the UE (user equipment) in RRC connected state to be able to perform CSI reporting only during the active period or DRX-onduration timer (discontinuous reception duration timer) running time after the DRX (discontinuous reception) configuration is turned on. Different CSI reporting has a period or a trigger condition, and due to the limitation of a reporting time window, the opportunity of reporting CSI by the UE that turns on DRX is greatly reduced, so that the situation that CSI-RS (channel state information reference signal) or SSB (synchronization signal block) resources or reported PUCCH/PUSCH resources that need to be measured are not present in the active period or DRX-onduration timer may occur. Therefore, for the UE in the connected state that turns on DRX, the base station cannot frequently acquire the channel state information due to the reduction of the CSI reporting opportunity. When the channel state changes rapidly, the accuracy of the base station to the UE scheduling is reduced. If the channel state is poor, the base station schedules the UE according to a higher MCS (modulation and coding strategy), which may cause the UE to fail to decode or lose packets. If the channel state is good, the base station schedules the UE according to the lower MCS, which may cause throughput degradation.
The base station can trigger the connected UE which is started with the DRX to carry out CSI measurement and reporting by sending other signals, and the base station is assisted to acquire the CSI information. Since CSI measurement and reporting are triggered by other signals, the reporting resources corresponding to the CSI measurement and reporting need to be configured. In the current protocol, the higher layer signaling only configures PUCCH resources associated with each periodic CSI report and semi-persistent CSI report, and for the reporting of the adaptive CSI, the UE needs to be instructed on which PUSCH resource to report through DCI.
Therefore, a new CSI reporting resource allocation method needs to be designed for CSI measurement and reporting under the condition of other signal triggers and non-DCI triggers.

The method for reporting channel state information according to the present invention is further described below with reference to a specific embodiment, taking a network side device as an example of a base station:
in this embodiment, the base station sends a first signal to the UE, and if the UE detects the first signal, the UE reports CSI.
The configuration of the CSI reporting resource comprises the following modes:
the first mode is: non-decoupling from measurement resource allocation
Specifically, PUCCH resources associated with the measurement resource configuration of CSI reporting may be configured through predefined and/or higher layer signaling. The format and/or time domain resources and/or frequency domain resources and/or code domain resources of the PUCCH resource are configured by predefined and/or higher layer signaling.
In a specific embodiment, the higher layer signaling associates a PUCCH resource with each measurement resource reported by CSI triggered by the first signal, where the first signal indicates and/or predefines and/or the higher layer signaling indicates the configuration of the measurement resource reported by CSI while implicitly indicating the reported PUCCH resource.
The second mode is as follows: decoupling from the measurement resource configuration includes five configuration methods.
The method comprises the following steps:
and configuring a PUCCH resource associated with the CSI reporting triggered by the first signal through predefined and/or higher-layer signaling. While predefining and/or higher layer signaling configures the format and/or time domain resources and/or frequency domain resources and/or code domain resources of the PUCCH resource.
In a specific embodiment, the higher layer signaling or predefining the PUCCH resource used for CSI reporting triggered by the first signal, that is, implicitly indicates the PUCCH resource to report if the first signal triggers CSI reporting of the UE.
The second method is as follows:
and configuring a PUCCH resource set associated with the CSI reporting triggered by the first signal through predefined and/or high-layer signaling, wherein the resource set comprises a plurality of PUCCH resources. The first signal indicates PUCCH resources for the UE to report the CSI.
The format and/or time domain resources and/or frequency domain resources and/or code domain resources of each PUCCH resource in the set of PUCCH resources are configured by predefined and/or higher layer signaling.
The specific first signal may be an indication of PUCCH resources by different bit states and/or cyclic shifts and/or sequence indexes. In addition, the association relation between different bit states and/or cyclic shifts and/or sequence indexes and PUCCH resources is also configured through predefined or higher layer signaling.
In a specific embodiment, the higher layer signaling or predefining the PUCCH resource set used by CSI reporting triggered by the first signal includes PUCCH resource 0, PUCCH resource 1, PUCCH resource 2 and PUCCH resource 3. The first signal is indicated by different bit states, e.g. 00 for PUCCH resource 0,01 for PUCCH resource 1,10 for PUCCH resource 2,11 for PUCCH resource 3. Or the first signal is indicated by a different cyclic shift, for example cyclic shift 0 represents PUCCH resource 0, cyclic shift 1 represents PUCCH resource 1, cyclic shift 2 represents PUCCH resource 2, and cyclic shift 3 represents PUCCH resource 3.
And a third method:
using the PUCCH-resource configured in the PUCCH-Config information element in the higher layer signaling, the UE implicitly selects which PUCCH resource set to use according to the number of CSI bits to be reported, where the first signal indicates the PUCCH resource used by the UE in the PUCCH set for CSI reporting.
The specific first signal may be an indication of PUCCH resources by bit state and/or cyclic shift and/or sequence index.
In a specific embodiment, the UE selects PUCCH resource set 2 by CSI bit number, and the first signal further indicates PUCCH resources used in PUCCH resource set 2.
The method four:
and using the PUCCH-resource set configured in the PUCCH-Config information element in the high-level signaling, implicitly selecting which PUCCH resource set to use by the UE through the number of the CSI bits to be reported, and predefining and/or configuring PUCCH resources for the UE to report the CSI in the selected PUCCH resource sets by the high-level signaling.
In a specific embodiment, the PUCCH resource with the smallest index in each PUCCH resource set is configured by predefined or higher layer signaling for reporting.
