Description

Technical Field

[0001] The present invention relates to the field of communication technology, and in particular to a CSI reporting method, a triggering method, an apparatus, a terminal and a network side device. Background Art

[0002] In NR (New Radio), there are three types of CSI (Channel State Information) reporting: periodic reporting, semi-static reporting, and non-periodic reporting. For a terminal in RRC (Radio Resource Control) connection state, when DRX (Discontinuous Reception) configuration is turned on, the NR protocol restricts the terminal to report CSI only during the DRX activation period or drx-onDurationTimer (DRX duration timer).

[0003] Terminal energy saving can be achieved to a certain extent through DRX. However, even if the terminal is configured with DRX, the terminal may not be scheduled at all in some DRX cycles. Therefore, in the research on terminal energy saving, one of the functions of energy saving signals is to indicate whether the terminal detects PDCCH within the associated DRX activation period or within the drx-onDurationTimer time. The energy saving signal adopts the structure of the downlink control channel and is detected outside the DRX activation period.

[0004] After the introduction of the energy-saving signal, the terminal does not need to detect the PDCCH in each DRX activation period, that is, it is impossible to perform semi-static CSI or non-periodic CSI reporting triggered by the PDCCH in each DRX activation period. In addition, if the measurement resources and reporting resources of the periodic CSI reporting configured by the network side do not match the DRX duration timer, the terminal cannot implement periodic CSI reporting. That is, after the introduction of the energy-saving signal, the opportunity for the terminal to report CSI is greatly reduced, and the base station cannot frequently and accurately obtain channel state information. When the channel state changes rapidly, the accuracy of the base station's scheduling of the terminal will decrease. 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 will cause the terminal to be unable to decode or packet loss. If the channel state is good, the base station schedules the terminal according to a lower MCS, which will cause a decrease in throughput and the like. In particular, when 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. At this time, if the terminal needs to be awakened to transmit data, it can only use an inaccurate MCS, resulting in a decrease in spectrum utilization efficiency and further increase in energy consumption of the terminal. Summary of the invention

[0005] The purpose of the embodiments of the present invention is to provide a CSI reporting method, triggering method, device, terminal and network side equipment to solve the problem in the prior art that the base station cannot obtain accurate CSI information in time, resulting in increased terminal energy consumption.

[0146] In order to make the technical problems, technical solutions and advantages to be solved by the present invention more clear, a detailed description will be given below with reference to the accompanying drawings and specific embodiments.

[0147] like Figure 1 As shown, an embodiment of the present invention provides a method for reporting channel state information CSI, which is applied to a terminal and includes:

[0148] Step 11, detecting energy-saving signals;

[0149] Step 12, when the energy-saving signal is detected, or when the detected energy-saving signal is used to instruct the terminal to report CSI, the terminal reports CSI through the physical uplink shared channel PUSCH resources before the start subframe of the discontinuous reception DRX cycle or before the start subframe of the DRX duration timer.

[0150] It should be noted that, in addition to the function of triggering or instructing the terminal to report CSI, the above energy-saving signal is also used to instruct or trigger the terminal to detect PDCCH within the next one or more DRX duration timers drx-onDurationTimer.

[0151] The embodiment of the present invention can use the energy-saving signal to trigger the terminal to measure and report CSI before the start subframe of the DRX cycle or before the start subframe of the RX duration timer. The network side device can receive accurate and timely CSI, so that data scheduling can be performed according to the optimal MCS after the drx-onDurationTimer runs.

[0152] Optionally, the energy-saving signal can be directly used to trigger the terminal to report CSI on the PUSCH resource, that is, if the energy-saving signal is detected, CSI is reported through the PUSCH resource; if the energy-saving signal is not detected, the terminal does not report CSI.

[0153] Alternatively, the energy-saving signal carries a first information field, which is used to indicate whether the terminal reports CSI; that is, the energy-saving signal is detected and parsed, and if the first information field of the energy-saving signal indicates that the terminal reports CSI, the terminal reports CSI through PUSCH resources; if the first information field of the energy-saving signal indicates that the terminal does not report CSI, the terminal does not report CSI.

[0154] It should be noted that the terminal needs to perform CSI measurement before reporting CSI. In order to ensure CSI measurement and reporting of the terminal, in the embodiment of the present invention, the method further includes:

[0155] Receiving configuration information of CSI reporting associated with the energy-saving signal configured by a network side device for the terminal, where the configuration information of the CSI reporting includes:

[0156] CSI resource configuration (CSI-ResourceConfig), used to configure CSI measurement signal resources;
