Description

Channel measurement reporting method, base station and terminal
Technical Field
The present invention relates to the field of wireless communication technologies, and in particular, to a channel measurement reporting method, a base station, and a terminal.
Background
When the base station performs data scheduling transmission for the terminal, it needs to determine a transmission format matching the current channel in consideration of the current channel state, and send data according to the transmission format or instruct the terminal (UE) to perform data transmission according to the transmission format. For example, when the channel state is good, a higher Modulation and Coding Scheme (MCS) is used for transmission, whereas a lower MCS is used for transmission, which ensures transmission reliability and improves transmission efficiency. In order to obtain the Channel state of downlink transmission, the UE needs to perform feedback reporting of Channel State Information (CSI).
The Channel State Information of the user can be obtained by measuring based on a Channel State Information Reference Signal (CSI-RS), and the CSI-RS is introduced in release10 of the 4G LTE, and is mainly used for the terminal to obtain the Channel State Information, and further used for Channel-related scheduling, link adaptation and multi-antenna transmission. In 5G NR, CSI-RS has more functions, such as: channel state information acquisition, beam management, connection state L3 mobility management, fine time/frequency tracking, uplink power control, wireless link detection, and the like.
On one hand, relevant parameters sent by the CSI-RS need to be configured to obtain the state information of the channel based on the measurement of the CSI-RS, wherein the relevant parameters comprise time-frequency resource positions sent by the CSI-RS, sequence characteristics of signals and the like; and on the other hand, physical resources for carrying CSI report need to be configured.
In NR, CSI reporting may have three types of periodic (periodic), semi-static (semi-periodic), and aperiodic (aperiodic). The periodic CSI report is configured by a high-level signaling to trigger CSI report, and a CHannel carrying CSI feedback is a Physical Uplink Control CHannel (PUCCH) and is also configured by the high-level signaling. The semi-static CSI reporting may be performed by configuring parameters through a high-level signaling, triggering sending of the CSI-RS, and reporting on a PUCCH resource, or triggering sending of a CSI-RS signal through Downlink Control Information (DCI), and reporting on a Physical Uplink Shared Channel (PUSCH) resource. The aperiodic CSI is reported on a PUSCH resource through high-level signaling configuration and DCI triggering.
For each CSI reporting type, the higher layer signaling configures each measurement signal (which may be a CSI-RS, or may also be a synchronization signal/physical broadcast channel block (SS/PBCH block, SSB)), the measured content, and the reported resource for the terminal.
When the configuration of Discontinuous Reception (DRX) is started, the terminal sleeps and activates at a certain period, and the protocol restricts the terminal to only report CSI during an active period or an active period timer (on duration timer).
Based on the existing CSI-RS reporting configuration, it cannot be guaranteed that the measurement transmission of the periodic CSI-RS is within the on duration timer of the DRX, and particularly, the measurement transmission of the periodic CSI-RS cannot necessarily occur in the initial stage of the on duration timer. For aperiodic CSI-RS reporting, DCI is needed to trigger measurement and reporting of CSI-RS, and a certain trigger time and measurement feedback time are needed. This means that the base station cannot acquire the channel state information in time when the discontinuously received terminal is in an active state, and the uplink and downlink data scheduling formats cannot adjust the transmission format in time according to the latest channel state information, thereby reducing the efficiency of data transmission.

Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the drawings of the embodiments of the present invention. It is to be understood that the embodiments described are only a few embodiments of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the described embodiments of the invention, are within the scope of the invention.
Referring to fig. 1, fig. 1 is a schematic flow chart of a channel measurement reporting method applied to a base station according to an embodiment of the present invention, where the channel measurement reporting method includes:
step 11: sending a first signal, where the first signal is used to instruct a terminal to perform or determine CSI reporting before starting a DRX-onduration timer (discontinuous reception-activation timer) or during a DRX cycle activation period or during a DRX-onduration timer running period after receiving the first signal; and the CSI reporting configuration is obtained according to the periodic or semi-continuous CSI reporting configuration configured by a high layer.
For a terminal configured with DRX, its DRX cycle active duration includes the active time declared in 38.321:
-a run period of drx-onDurationTimer or drx-inactivity timer (non-connection reception-deactivation timer) or drx-retransmission timerdl (downlink non-connection reception-retransmission timer) or drx-retransmission timerll (uplink non-connection reception-retransmission timer) or ra-ContentionResolutionTimer (random access procedure contention resolution timer); or
An SR (scheduling) request is sent on a PUCCH (physical uplink control channel), and a response is not received (in a pending stage); or
-a random access response has been successfully received, which random access response corresponds to a random access sequence that the MAC (medium access control) entity has not selected from the contention based random access sequences, but has not received a PDCCH indication new data transmission corresponding to the C-RNTI (cell radio network temporary identity) of the MAC entity.
In the embodiment of the invention, the base station can send the first signal to the terminal to inform the terminal to report the CSI in time, so that the best matching data scheduling format can be adopted according to the CSI reported by the terminal, and the data transmission efficiency and reliability are improved.
In some embodiments of the present invention, a specified offset value exists between the reporting time domain resource location of the CSI report and the reporting time domain resource location of the periodic or semi-persistent CSI reporting configuration configured by the higher layer, or between the reporting time domain resource location of the CSI report and the sending time domain resource location of the first signal.
In some other embodiments of the present invention, the time domain resource location reported by the CSI is obtained by updating a period and offset value parameter, where the updated period and offset value parameter are determined by a specified offset value and the period and offset value parameter in the period configured by the higher layer or the period and offset value parameter in the semi-persistent CSI reporting configuration.
For example, the periodicity and offset parameters in the periodic CSI reporting configuration may take one of the following values:
Figure BDA0001785577910000081
it is assumed that the period and offset parameters in the periodic CSI reporting configuration are slots10 — interval (0..9), which means that the period is 10 slots, and the offset value is one of 0 to 9, for example, 5. Assuming that a designated offset value carried by the predefined, or high-level configuration or the first signal is 1, an updated period and offset value parameters can be obtained according to the designated offset value, that is, the period is 10 slots, and the offset value is 1. And obtaining the reporting time domain resource position reported by the CSI based on the updated period and the offset value parameter.
In the embodiment of the present invention, the updated period and offset value parameters triggered by the first signal may only be valid for the first CSI report after triggering or for multiple CSI reports, for example, for the next activation period of the DRX cycle.
In this embodiment of the present invention, the specified offset value in the two embodiments is a predefined value, or is configured to the terminal by the base station through a high-level signaling, or is carried by the first signal.
In the embodiment of the present invention, optionally, other configurations adopted for CSI reporting, except for reporting the time domain resource location, are partially or completely the same as the configurations of the periodic or semi-persistent CSI reporting. The other configurations include, for example, reported content and/or reported format.
In this embodiment, when the first signal indicates that there is an effective data scheduling for the user during the DRX activation period, the configuration for periodic or semi-persistent CSI reporting is moved from the time domain resource location originally reported to a certain time domain resource location after the first signal.
As shown in FIG. 2, the C-DRX (connected-state discontinuous reception) period is 160ms, and the DRX-on duration timer is 10 ms. Referring to the original reporting in fig. 2 (i.e., prior art), according to the periodic CSI reporting configuration in fig. 2, the base station cannot obtain the channel state information at the initial on-duration. In the embodiment of the present invention, the change of the CSI reporting time domain position may be triggered by the first signal (see configuration mode 1-1 and configuration mode 1-2 in fig. 2). Whether effective data scheduling exists in the on duration is indicated through a first signal sent before the on duration, when the effective data scheduling exists, CSI reporting is triggered, the reported time domain resource is a certain time position after the first signal, and the reported time domain resource position can be determined through an indication period and an offset value of an offset value parameter, or an indication CSI reporting time and the offset value of the first signal or the original period CSI reporting time. Configuration of other CSI reports such as reporting content, reporting format, etc. refers to configuration of periodic CSI reports. The measurement reporting in situ may be unaffected or cancelled (see dashed arrow in fig. 2, indicating the cancellation of the original periodic CSI reporting in that location).
In this embodiment of the present invention, the first signal may be further configured to instruct the terminal to perform CSI measurement after receiving the first signal and before performing the CSI report.
In some embodiments of the present invention, a specified offset value exists between a time domain resource position of the CSI resource measured by the CSI measurement and a time domain resource position of a periodic or semi-persistent CSI resource, or a transmission time domain resource position of the first signal.
In some further embodiments of the present invention, the time domain resource location of the CSI resource for the CSI measurement is determined according to a specified offset value and periodic and offset value parameters in a periodic or semi-persistent CSI resource configuration.
For periodic and semi-persistent CSI measurement resources (e.g., CSI-RS), the terminal may assume that the slot in which the CSI-RS is transmitted satisfies:
Figure BDA0001785577910000091
wherein n isfIs the radio frame number, ns,fNumbering slots within a radio frame,
Figure BDA0001785577910000101
for the number of time slots, T, contained in a radio frame with subcarrier spacing muCSI-RSPeriod of CSI-RS, ToffsetIs an offset value. Therefore, the sending position of the CSI-RS measurement resource can be obtained by obtaining the updated period and the offset value, and similarly, the resource position reported by the CSI can also be obtained.
In this embodiment of the present invention, the specified offset value in the two embodiments is a predefined value, or is configured to the terminal by the base station through a high-level signaling, or is carried by the first signal.
In the embodiment of the present invention, the specified offset value used for CSI measurement may be the same as or different from the specified offset value used for CSI reporting.
In the embodiment of the present invention, other configurations of the CSI resource for CSI measurement, except for the location of the time domain resource, are partially or completely the same as the configuration of the periodic or semi-persistent CSI resource.
In the embodiment of the present invention, the CSI reporting and/or CSI measurement triggered by the first signal may occur in an inactive period of DRX, whereas in the existing protocol, the terminal may only perform CSI reporting in an active period.
In this embodiment of the present invention, the first signal may be further used to indicate an active status in at least one next DRX cycle.
Optionally, the indicating the active state in the next at least one DRX cycle by the first signal includes:
1) indicating whether a DRX-duration timer is started for at least one next DRX cycle, satisfying a DRX-short cycle (discontinuous reception-short cycle) to StartOffset parameter constraint, and/or satisfying a DRX-long cycle (discontinuous reception-long cycle) to DRX-slot offset parameter constraint, and/or satisfying a time position of the DRX-slot offset parameter constraint; alternatively, the first and second electrodes may be,
2) indicating whether to detect a Physical Downlink Control Channel (PDCCH) in an active period of at least one next DRX period; or
3) Indicating a time position satisfying the constraint relation between the DRX-ShortCycle and the StartOffset parameter and/or a time position satisfying the constraint relation between the DRX-LongCycle and the DRX-SlotOffset parameter and/or a time position satisfying the DRX-SlotOffset parameter constraint in at least one next DRX period, and starting a DRX-onDurationTimer; alternatively, the first and second electrodes may be,
4) indicating that the PDCCH is detected during an active period of at least one DRX cycle that follows.
In the above 3) and 4), the first signal may be used to indicate that DRX-onduration timer needs to be started or PDCCH needs to be detected in at least one next DRX cycle, and indicate, after receiving the first signal, before DRX-onduration timer is started or during DRX cycle activation or during DRX-onduration timer operation, or whether CSI reporting is performed or not, that is, when there is effective PDCCH scheduling in an active period, the terminal is indicated to perform CSI reporting, so that it is possible to avoid that terminal energy consumption is too large.
