Description

Measurement reporting and configuration method, terminal and network side equipment

Technical Field

The present invention relates to the field of communications technologies, and in particular, to a measurement reporting method, a measurement configuring method, a terminal, and a network device.

Background

Future fifth Generation (5Generation, 5G) mobile communication systems need to accommodate more diverse scenarios and service demands than previous mobile communication systems. The main scenes of 5G include enhanced mobile broadband (eMBB), Ultra-high Reliable and Low Latency Communications (URLLC), and large-scale internet of things (mtc), and these scenes have proposed requirements for the system such as high reliability, Low Latency, large bandwidth, and wide coverage. For Channel State Information (CSI) measurement, the higher layer configures the terminal with N CSI-ReportConfig Report settings (reporting setting) and M CSI-ResourceConfig Resource settings (Resource setting), and one or 2 trigger State lists. The CSI resource is used for CSI measurement, and in a CSI resource setting (setting), there are Reference Signals (RS) used for channel measurement and RSs used for interference measurement, and a User Equipment (UE, also called a terminal) performs CSI calculation according to these RSs. And then the terminal reports according to the report setting, such as periodic CSI report, semi-continuous CSI report and aperiodic CSI report.

The URLLC service has two service models, namely a period determination service and a burst service, and the terminal speed is not high in a typical scenario in consideration of its high reliability requirement. In general, channel measurements do not change frequently, and the main factor affecting CSI computation is interference. Since the interference may vary strongly, for example, the interference situation of the terminal may change rapidly, for example, from time slot to time slot, due to intra-cell or inter-cell interference variations. Therefore, the measurement of interference is a main factor affecting the accuracy of CSI measurement. However, the existing CSI reporting needs to perform channel measurement and interference measurement each time, which causes the problems of high signaling overhead and long CSI feedback delay.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in detail with reference to the accompanying drawings and specific embodiments.

The invention provides a measurement reporting method and a terminal aiming at the problems of higher signaling overhead and longer CSI feedback time delay caused by the existing CSI measurement reporting mode.

As shown in fig. 1, an embodiment of the present invention provides a measurement reporting method, which is applied to a terminal, and includes:

step 101, under the condition of only triggering first measurement, measuring through a corresponding first reference signal to obtain a first measurement result;

wherein the first measurement is one of a channel measurement and an interference measurement;

step 102, determining Channel State Information (CSI) reporting information according to the first measurement result and the second measurement result, and sending the CSI reporting information to network side equipment;

it should be noted that the second measurement result is a measurement result of a second reference signal corresponding to a second measurement, and the second measurement is the other one of the channel measurement and the interference measurement.

It should be noted that, to acquire the CSI report information, it is necessary to acquire an interference measurement result and a channel measurement result, and only one measurement result required for the CSI report is acquired in step 101, and another measurement result is also acquired here, that is, when the first measurement result obtained in step 101 is the interference measurement result, the second measurement result is the channel measurement result, and when the first measurement result obtained in step 101 is the channel measurement result, the second measurement result is the interference measurement result. Specifically, after the terminal acquires the interference measurement result and the channel measurement result, the CSI report information can be determined according to the two measurement results, and the obtained CSI report information is fed back to the network side device.

For example, the signal quality of the channel part of the terminal is slowly changed, the channel measurement quality for CSI calculation can be obtained by the latest channel measurement, and the terminal can measure only interference, that is, the terminal only needs to update the measurement of the interference part, which is beneficial to reducing the processing time for CSI calculation.

It should be noted that the second reference signal is triggered periodically or aperiodically.

When the second reference signal is a periodically triggered RS, after the terminal acquires the first measurement result, acquiring a second measurement result obtained by performing channel measurement or interference measurement on the periodic RS which is closest to the acquisition time of the first measurement result; and when the second reference signal is the aperiodic triggering RS, after the terminal acquires the first measurement result, acquiring a second measurement result obtained by performing channel measurement or interference measurement on the aperiodic RS which is closest to the acquisition time of the first measurement result. For example, when only channel measurement is triggered, CSI reporting information may be determined according to a first measurement result of the channel measurement and a second measurement result of interference measurement performed by a latest periodic/aperiodic interference measurement RS. Or, when only the interference measurement is triggered, the CSI reporting information may be determined according to the first measurement result of the interference measurement and the second measurement result of the channel measurement performed by the latest periodic/aperiodic channel measurement RS.

In another embodiment, the second measurement result is a measurement result of a second reference signal indicated by the first CSI reporting configuration; specifically, the first CSI report is configured to configure configuration information of the first reference signal, or the first CSI report is configured to configure configuration information associated with the first reference signal.

It should be noted here that when the first CSI report is configured to configure the configuration information of the first reference signal, that is, the configuration information of the reference signal corresponding to the channel measurement and the interference measurement is configured in the CSI report configuration corresponding to each CSI report (that is, the configuration information of the first reference signal and the second reference signal is configured in the CSI report configuration), except that the measurement triggered by each terminal is different, when the current trigger is the channel measurement, the second measurement result corresponds to the measurement result obtained by measuring the latest second reference signal in the CSI report configuration. Or, when the first CSI report is configured as configuration information associated with the first reference signal, that is, in this case, configurations of reference signals configured in CSI report configurations corresponding to different CSI reports are different, that is, the current CSI report needs to be associated with a CSI report configuration that has been previously obtained, so as to facilitate a terminal to determine a measurement result that does not perform information measurement in the current CSI report.

Specifically, the second reference signal is a reference signal closest to the first reference signal, that is, the second measurement result is an available measurement result corresponding to the first CSI report configuration that is shortest in time from the time of obtaining the first measurement result, that is, the second measurement result is an available measurement result corresponding to the first CSI report configuration that is available most recently.

It should be noted that, the available measurement result that is the closest or shortest from the time of acquiring the first measurement result mentioned above refers to: an available measurement that is the closest or the same time slot (mini-slot) before the first measurement acquisition instant.

It should be further noted that, the first measurement in the embodiment of the present invention may be configured by a network side device, or may be agreed by a protocol, and specifically, when the first measurement is configured by the network side device, one of the following schemes may be adopted to implement:

scheme I,

Before step 101, the method for reporting measurement according to the embodiment of the present invention further includes:

receiving a CSI report configuration, wherein the CSI report configuration carries configurations of a first reference signal and a second reference signal;

receiving a trigger indication, wherein the trigger indication is used for triggering the first measurement.

It should be noted that the implementation conditions of this implementation are as follows: configuration information of reference signals corresponding to channel measurement and interference measurement is configured in a CSI report configuration corresponding to each CSI report (that is, configuration information of a first reference signal and a second reference signal is configured in the CSI report configuration), and a network side device needs to use an additional trigger instruction to tell a terminal which reference signal is to be measured this time, specifically, the trigger instruction may be Downlink Control Information (DCI).

It should be noted that, for one CSI report configuration, the CSI report configuration may include m channel measurement reference signals and n interference measurement reference signals, and the network side device may trigger (for example, through DCI) the different channel measurement reference signals and the interference measurement reference signals to perform CSI measurement and report.

For example, one CSI report configuration 1, the network side device may configure 1 channel measurement reference signal and 2 interference measurement reference signals for the terminal. And at the moment 1, the network side equipment triggers the terminal to use the reference signal 1 corresponding to the interference measurement to carry out the interference measurement, use the reference signal corresponding to the channel measurement to carry out the channel measurement, and then carry out CSI calculation and report. At time 2, the network side device may trigger the terminal to perform interference measurement only by using the reference signal 2 corresponding to the interference measurement, and at this time, the terminal may use the channel measurement result calculated before without performing channel measurement again by using the reference signal corresponding to the channel measurement, and only needs to perform interference measurement by using the reference signal 2 corresponding to the interference measurement. That is, at time 1, for the terminal configured with CSI report configuration 1, the network side device triggers the terminal to perform channel measurement and interference measurement simultaneously through DCI, and performs CSI reporting. At time 2, for the terminal configured with CSI report configuration 1, the network triggers the terminal to perform interference measurement only through DCI, and performs CSI reporting.

It should be further noted that the trigger instruction is also used to trigger reporting of CSI report information, that is, after the terminal receives the trigger instruction and performs corresponding information measurement to obtain CSI report information, the terminal performs reporting of CSI report information at a specific time.

Scheme II,

receiving a CSI reporting configuration for triggering a first measurement.

It should be noted that the implementation conditions of this implementation are as follows: the configuration information of the reference signals configured in the CSI report configuration corresponding to each CSI report is not completely the same, that is, the network side device does not need to use an additional trigger instruction to tell the terminal which reference signal is to be measured this time, and after the terminal acquires the CSI report configuration, which reference signal configuration information is indicated in the CSI report configuration, the terminal performs corresponding measurement according to the CSI report configuration indication.

The following specifically describes embodiments of the present invention from different implementation perspectives.

For example, when configuration information of reference signals corresponding to channel measurement and interference measurement is configured in each CSI report configuration corresponding to CSI reporting, the terminal determines which measurement is to be performed according to the DCI indication, for example, as shown in fig. 2, the configuration information of the RS for channel measurement and the configuration information of the RS for interference measurement are configured in the CSI report configuration, when the DCI received by the terminal indicates that the terminal performs channel measurement and interference measurement, the terminal receives the reference signals at corresponding times to perform channel measurement and interference measurement, and then performs feedback of the CSI report information at a CSI reporting time t1, where a diagonal filling box represents the RS for interference measurement, a grid filling box represents the RS for channel measurement, and a horizontal line filling box represents the DCI.

For example, when configuration information of a reference signal corresponding to channel measurement and interference measurement is configured in a CSI report configuration corresponding to each CSI report, the terminal determines which measurement is to be performed according to DCI indication, for example, as shown in fig. 3, the CSI report configuration 1 configures configuration information of an RS for channel measurement and configuration information of an RS for interference measurement, when the DCI received by the terminal indicates that the terminal performs interference measurement, the terminal receives the reference signal at a corresponding time to perform interference measurement, and then performs feedback of the CSI report information at a CSI report time t1, where a diagonal filling box represents a latest available RS for channel measurement, a grid filling box represents a latest RS for interference measurement, a horizontal filling box represents DCI, and a vertical filling box represents an RS triggered by DCI for interference measurement.

For example, when configuration information of a reference signal corresponding to channel measurement and interference measurement is configured in a CSI report configuration corresponding to each CSI report, the terminal determines which measurement is to be performed according to the DCI indication, for example, as shown in fig. 4, the CSI report configuration 1 configures configuration information of an RS for channel measurement and configuration information of an RS for interference measurement, when the DCI received by the terminal indicates that the terminal performs channel measurement, the terminal receives the reference signal at a corresponding time to perform channel measurement, and then performs feedback of the CSI report information at a CSI report time t1, where a grid filling box represents a most recently available RS for interference measurement, a diagonal filling box represents a most recent RS for channel measurement, a horizontal filling box represents DCI, and a vertical filling box represents an RS triggered by the DCI to perform channel measurement.

For example, when configuration information of reference signals corresponding to channel measurement and interference measurement is configured in each CSI report configuration corresponding to CSI reporting, the terminal determines which measurement to perform according to the DCI instruction, as shown in fig. 5, when an RS for CSI feedback at a time before receiving DCI is a periodic RS, and when DCI triggers interference measurement, the terminal performs interference measurement using the periodic RS for interference measurement at a time after receiving DCI, and then performs feedback of CSI reporting information at a CSI reporting time t1, where a diagonal filling box indicates a most recently available RS for channel measurement, a grid filling box indicates a most recent RS for interference measurement, a horizontal filling box indicates DCI, and a vertical filling box indicates an RS for interference measurement triggered by DCI.

For example, when the configurations of the reference signals configured in the CSI reporting configurations corresponding to different CSI reports are different, that is, the CSI report needs to be associated with the CSI report configuration that has been obtained previously, for example, when only interference measurement is triggered, the network side device may configure the RS for channel measurement associated with CSI measurement configuration 1 for CSI calculation, for example, when the triggering indication is triggered to be interference measurement, as shown in fig. 6, using the RS for channel measurement that is most recently available, CSI measurement configuration 1 is associated with the triggering indication, then the RS for channel measurement corresponding to the CSI measurement configuration 1 before the trigger indication is used for CSI calculation, the diagonal filling boxes represent the latest available RS for channel measurement, the grid filling boxes represent the latest RS for interference measurement, the horizontal filling boxes represent DCI, and the vertical filling boxes represent the RS triggered by DCI for interference measurement.

It is further noted that the type of the first CSI reporting configuration includes one of:

periodic CSI reporting, semi-persistent CSI reporting, and aperiodic CSI reporting.

It should be further noted that, for different information measurements triggered by the network-side device, the terminal processing time may be different. Specifically, the processing time used by the terminal to perform channel measurement or interference measurement is a first time, and the processing time used by the terminal to perform channel measurement and interference measurement simultaneously is a second time; the processing time of the terminal here may be the processing capacity of the terminal, i.e. the time required for the terminal having this capacity to perform the processing. The processing time mentioned below may refer to the processing capacity.

Wherein the first time is less than or equal to the second time.

The setting mode can ensure that the terminal occupies less time for information measurement as much as possible, and can save time overhead, which is very important for services with low time delay and high reliability requirements.

It should be further noted that the CSI report information includes some of the following parameters:

rank Indication (RI), Precoding Matrix Indication (PMI), and Channel Quality Indication (CQI).

Further, different processing times may be associated with the content of the CSI report information to be fed back by the terminal configured by the network side device.

For example, if the network side device instructs the terminal to report { RI, PMI, CQI }, the terminal may use the processing time C;

if the network side equipment indicates the terminal to report any two of { RI, PMI and CQI }, the terminal can use the processing time D;

if the network side equipment indicates the terminal to report any one of { RI, PMI and CQI }, the terminal can use the processing time E.

Specifically, the processing time E is less than or equal to the processing time D, and the processing time D is less than or equal to the processing time C.

It should be further noted that the reference signals (i.e., the first reference signal and the second reference signal) mentioned in the embodiments of the present invention include: a demodulation reference signal (DMRS, specifically, the DMRS may be a DMRS of a PDSCH, or may also be a DMRS of a PDCCH), a channel state information reference signal (CSI-RS), and at least one of Physical Downlink Shared Channel (PDSCH) resources configured by a network side device, for example, a set of Resource Elements (REs) of some PDSCHs.

In the embodiment of the invention, when only the first measurement is triggered, only the channel measurement or the interference measurement is carried out, so that the signaling overhead can be reduced, the time occupied by the measurement can be reduced, and the feedback delay of the CSI can be further reduced.

As shown in fig. 7, an embodiment of the present invention provides a terminal 700, including:

an obtaining module 701, configured to measure through a corresponding first reference signal to obtain a first measurement result when only a first measurement is triggered, where the first measurement is one of a channel measurement and an interference measurement;
