Description
Technical Field
The present invention relates to the field of communications technologies, and in particular, to a CSI reporting method, a CSI triggering method, a CSI reporting device, a CSI terminal, and a network side device.
Background
There may be three types of CSI (Channel State Information) reporting in NR (New Radio, New air interface), which are respectively: periodic reporting, semi-static reporting, and aperiodic reporting. When a terminal in an RRC (Radio Resource Control) connected state starts a DRX (Discontinuous Reception) configuration, the NR protocol restricts the terminal to only report CSI during a DRX active period or a DRX on duration timer.
Terminal power saving can be achieved to some extent by DRX, however, even if the terminal is configured with DRX, it may happen that the terminal is not scheduled at all during some DRX cycles. Therefore, in the terminal power saving study, one of the roles of the power saving signal is to indicate whether the terminal detects the PDCCH in the associated DRX active period or DRX on duration timer. The energy-saving signal adopts a structure of a downlink control channel and is detected outside an activation period of DRX.
After the energy-saving signal is introduced, the terminal does not need to detect the PDCCH in each DRX active period, that is, semi-static CSI or aperiodic CSI report triggered by the PDCCH cannot be performed in each DRX active period. In addition, if the measurement resource and the reporting resource configured on the network side for periodic CSI reporting are not matched with the DRX duration timer, the terminal cannot realize periodic CSI reporting. That is, after the energy-saving signal is introduced, the opportunity of reporting the CSI by the terminal is greatly reduced, and the base station cannot frequently and accurately obtain the channel state information. When the channel status changes rapidly, the accuracy of the base station to schedule the terminal may be reduced. If the channel state is poor, the base station schedules the terminal according to a higher MCS (Modulation and Coding Scheme, Modulation and Coding strategy), which may result in that the terminal cannot decode or loses packets. If the channel state is good, the base station schedules the terminal according to a low MCS, which may cause a decrease in throughput. Especially, after the terminal sleeps for a long time without detecting the PDCCH, the base station cannot obtain the current timely and accurate CSI information of the terminal, and at this time, if the terminal needs to be awakened to transmit data, only an inaccurate MCS can be adopted, so that the spectrum utilization efficiency is reduced, and the terminal further increases energy consumption.

Detailed Description
In order to make the technical problems, technical solutions and advantages of the present invention more apparent, the following detailed description is given with reference to the accompanying drawings and specific embodiments.
As shown in fig. 1, an embodiment of the present invention provides a method for reporting CSI, which is applied to a terminal, and includes:
and step 12, when the energy-saving signal is detected, or when the detected energy-saving signal is used for indicating the terminal to report the CSI, the terminal reports the CSI through the PUSCH resource of the physical uplink shared channel before the starting position of the DRX cycle is discontinuously received or before the starting subframe of the DRX duration timer.
It should be noted that the energy saving signal is used for instructing or triggering the terminal to detect the PDCCH in the next DRX duration timer or timers operation, in addition to the function of triggering or instructing the terminal to report the CSI.
The embodiment of the invention can use the energy-saving signal to trigger the terminal to carry out the measurement and report of the CSI before the starting position of the DRX period or before the starting subframe of the RX duration timer, and the network side equipment can receive the accurate and timely CSI, thereby carrying out the data scheduling according to the optimal MCS after the operation of the DRX-onDuration timer.
Optionally, the energy-saving signal may be directly used to trigger the terminal to perform CSI reporting on the PUSCH resource, that is, if the energy-saving signal is detected, the CSI reporting is performed through the PUSCH resource; and if the energy-saving signal is not detected, the terminal does not report the CSI.
Or, the energy-saving signal carries a first information field, and the first information field is used for indicating whether the terminal reports the CSI; the terminal analyzes the energy-saving signal when detecting the energy-saving signal, and reports CSI through a PUSCH resource if a first information domain of the energy-saving signal indicates the terminal to report CSI; and if the first information field of the energy-saving signal indicates that the terminal does not carry out CSI reporting, the terminal does not carry out CSI reporting.
It should be noted that, the CSI measurement needs to be performed before the CSI report is performed by the terminal, and in order to ensure the CSI measurement and report of the terminal, in the embodiment of the present invention, the method further includes:

Regarding the determination of the PUSCH resource for reporting the CSI by the terminal, the embodiment of the present invention provides the following two ways:
the first method is as follows: a power saving signal indication;

the method further comprises the following steps:
and determining the PUSCH resource for CSI reporting according to the indication of the energy-saving signal.
For example, the energy-saving signal carries a second information field and a third information field, where the second information field is used to instruct the terminal to perform time domain resource allocation of PUSCH resources for CSI reporting; and the third information field is used for indicating the terminal to carry out frequency domain resource allocation of PUSCH resources reported by the CSI.
The second method comprises the following steps: configuring network side equipment;

an antenna port;
precoding information;
number of layers.
For example, the network side device pre-configures configuration information of the PUSCH resource reported by the CSI for the terminal through a high-level signaling.
Optionally, the time domain resource allocation information includes:
a slot offset value between the time domain resource of the PUSCH resource and the time domain resource of the energy saving signal;
wherein a time slot offset value between the time domain resource of the PUSCH resource and the time domain resource of the energy saving signal is smaller than a target value; the target value is a time domain distance between the energy-saving signal and a starting subframe of a DRX period starting position or a DRX duration timer.
In summary, in the embodiments of the present invention, the terminal performs CSI reporting through the PUSCH resource before the starting position of the DRX cycle or before the starting subframe of the DRX duration timer according to the energy saving signal trigger or the indication, so that the network side device can obtain accurate and timely CSI, and thus data scheduling can be performed according to the optimal MCS after the DRX duration timer runs, thereby improving the spectrum utilization and avoiding increasing the energy consumption of the terminal.
As shown in fig. 2, an embodiment of the present invention further provides a method for triggering CSI report, which is applied to a network side device, and includes:
