Description

Measurement reporting method, configuration method, terminal and network equipment of CSI
Technical Field
The present invention relates to the field of communications technologies, and in particular, to a method for reporting CSI measurement, a method for configuring CSI measurement, a terminal, and a network device.
Background
In NR (New Raido, new air interface), CSI (Channel State Information ) reporting may have three reporting types, i.e., periodic, semi-persistent or semi-static, and aperiodic. Wherein, the periodic CSI reporting is performed on PUCCH (Physical Uplink Control Channel ) resources through higher layer signaling configuration and triggering. semi-persistent CSI reporting may be reported on PUCCH resources by higher layer signaling configuration and triggering, or on PUSCH (Physical Uplink Shared Channel ) resources by DCI (Downlink Control Information, downlink control information) triggering. Reporting the Aperiodic CSI is performed on the PUCCH resource by configuring a high-level signaling and triggering DCI. For each CSI reporting type, the higher layer signaling configures a reporting corresponding measurement signal, a measured content and a reported resource for the terminal.
A terminal in RRC (Radio Resource Control ) connected state, when DRX (discontinuous reception) configuration is turned on, the protocol restricts the terminal to CSI reporting only during an active period or on duration timer (duration timer) time. It may occur that the CSI-RS (CSI reference signals, channel state information reference signal) or SSB (Synchronization Signal Block ) resources or the reported PUCCH or PUSCH resources need to be measured do not occur within the active period or on duration timer. Therefore, for the connected terminal that starts DRX, due to the reduction of CSI reporting opportunities, the base station cannot frequently acquire CSI, especially, the first several scheduling opportunities in on duration timer, where CSI is difficult to acquire, and thus, the base station may have a great influence on the scheduling of the terminal by the base station.
In the current flow of NR BWP (Band Width Part), higher layer signaling configures a set (up to 4) of downlink BWP and a set (up to 4) of uplink BWP for a terminal. For TDD (Time Division Duplexing, time division duplex), one downlink BWP and one uplink BWP are associated, forming one BWP pair, and the center frequencies of the uplink and downlink BWP are the same. But the terminal can only operate on one active BWP at a time, the base station may activate and deactivate the BWP through RRC signaling, or may indicate in the DCI which active BWP the terminal is in for data reception or transmission through the BWP indicator. However, measurement and reporting of the target CSI can only occur on active BWP and cannot occur on inactive BWP.
In the current NR carrier aggregation procedure, higher layer RRC signaling adds, deletes or modifies scells (secondary cells) for terminals. The secondary cell activation or deactivation mechanism is implemented based on a combination of a secondary cell activation or deactivation MAC CE (Media Access Control-Control Element, medium access Control layer Control Element) and a deactivation timer (Scell Deactivation Timer). The first mode is based on activation/deactivation of the MAC CE, and after receiving the MAC CE to activate/deactivate the Scell, the terminal determines whether the corresponding Scell is activated or deactivated according to the information of the MAC CE. The second way is timer-based Scell deactivation, where the terminal maintains a deactivation timer for each Scell, and when the terminal does not receive data or PDCCH (Physical Downlink Control Channel ) message on the corresponding Scell within the time specified by the deactivation timer, the Scell will deactivate. The timer can only be used as a way for the terminal to deactivate the Scell itself, but not as a way for the terminal to activate the Scell. Meanwhile, the current CSI measurement and reporting can only occur on the activated Scell, but not on the inactivated Scell.
After DRX is turned on, the terminal can only perform CSI reporting in the active period or on duration timer, and since different CSI reporting has its period or trigger condition. Due to the limitation of the reporting time window, the opportunity of reporting the CSI by the terminal which starts the DRX is greatly reduced, and the base station cannot frequently and accurately acquire the channel state information. When the channel state changes rapidly, the accuracy of the base station to the terminal scheduling is 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 can lead to the terminal failing to decode or losing packets and retransmitting continuously. If the channel state is good, the base station schedules the terminal according to the lower MCS, which can cause the throughput to be reduced, and meanwhile, more scheduling opportunities are needed to transmit data and the like. Therefore, the base station cannot obtain effective CSI at the initial stage of the DRX cycle, which results in reduced spectrum efficiency, and the terminal needs more time to receive data, which results in power consumption of the terminal.
In BWP handover scenarios, the terminal is currently based on DCI or RRC handover signaling and switches to the indicated BWP after receiving the signaling. However, before that, the base station cannot obtain the channel state information on the new BWP, and the base station can report or effectively obtain the CSI through the measurement of the terminal only after the terminal is switched to the new BWP, which also causes the situation that the CSI in a period of time before the terminal is switched to the new BWP cannot be effectively obtained, so that the terminal consumes energy.
In the Scell activation scene, the terminal cannot report the measurement of the CSI on the inactive Scell, and the base station can only wait for the measurement report of the CSI after the terminal activates the Scell, so that the situation that the CSI in a period of time before the activation of a new Scell cannot be effectively acquired can occur, and the terminal consumes energy.

In order to more clearly describe the CSI measurement method and the CSI configuration method provided by the embodiments of the present invention, the following details are described in connection with several examples.
Example one
The base station configures a certain CSI-RS resource for the terminal, where the CSI-RS resource has 4 ports, port 0, port1, port2 and port3. The base station configures port 0 of the CSI-RS resource of the terminal as a first signal for triggering the terminal to report the CSI, and all 4 ports of the CSI-RS resource are second signals of measurement resources for reporting the CSI. If the terminal detects port 0 of the CSI-RS resource, the terminal reports the CSI by taking all ports of the CSI-RS resource as measurement resources.
Example two
The base station is configured to a certain CSI-RS resource #1 of the terminal, and the CSI-RS resource #1 is used as a first signal for triggering the terminal to report CSI. The base station configures a second signal which is used as a measurement resource for reporting the CSI and is associated with the CSI-RS resource #1 and the CSI-RS resource #2 of the terminal. If the terminal detects the CSI-RS resource #1, the terminal reports the CSI by taking the CSI-RS resource #2 as a measurement resource.
Example three
The base station configures a port 0 of a CSI-RS resource for the terminal, wherein the time domain resource position is positioned before the DRX-onduration timer runs (namely before the DRX period) and is used as a first signal for triggering the terminal to report the CSI. And simultaneously configuring all ports of the CSI-RS resource as a second signal of the measurement resource reported by the CSI. And the terminal detects a first signal (port 0 of the CSI-RS resource) before the drx-onduration timer runs, and if the first signal is detected, all ports of the CSI-RS resource are used as measurement resources to report the CSI. The base station can optimize resource scheduling after the drx-onduration timer operates according to the CSI reported by the terminal.
Example four
The base station configures a CSI-RS resource #1 on the active BWP #1 for the terminal, and uses the configured CSI-RS resource #1 as a first signal for triggering the terminal to report the CSI of the inactive BWP # 2. And simultaneously, the CSI-RS resource #2 on the inactive BWP #2 is configured as a second signal of the measurement resource for CSI reporting. The terminal detects the first signal at the corresponding time-frequency domain position according to the configuration of the base station, and if so, the terminal reports the CSI on the inactive BWP #2 by taking the CSI-RS #2 as a measurement resource. The base station may decide whether to switch the terminal to the inactive bwp#2 with better channel state according to the CSI reported by the terminal on the inactive bwp#2.
Example five
The base station configures a CSI-RS resource #1 on an activated main cell (pcell) for a terminal, and the CSI-RS resource #1 is used as a first signal for triggering the terminal to report the CSI of an inactive auxiliary cell # 1. And simultaneously configuring the CSI-RS resource #2 on the non-activated secondary cell #1 as a second signal of the measurement resource for CSI reporting. And the terminal detects the first signal at the corresponding time-frequency domain position according to the configuration of the base station, and if the first signal is detected, the CSI-RS resource #2 on the non-activated auxiliary cell #1 is used as a measurement resource to report the CSI. The base station may determine whether to activate and schedule the inactive secondary cell #1 of the terminal according to CSI reported by the terminal in the relevant inactive secondary cell # 1.
