Technical Field

Background
The New air interface (NR) introduces beam scanning to enhance coverage, enabling coverage over longer distances by using narrower synchronization signal block (Synchronization Signal and PBCH block, SSB) beams that are directional.

Detailed Description
From standard design to network planning, the design is performed according to the coverage of cells which are equal, but in actual network deployment, some scenes always exist, so that coverage short boards in certain directions appear. For example, under the coverage of the same cell, one direction experiences a larger attenuation due to dense trees or buildings, resulting in poor coverage in that direction and lower user rate.
A hierarchical coverage design may thus be considered, based on a partial Bandwidth Part (BWP) structure, to implement multiple candidate initial (initial) BWP accesses by transmitting SSBs of multiple cell definitions (cell definitions) in the same cell. While supporting different coverage levels on different initial BWP. Known as hierarchical coverage, i.e. different levels of coverage are distinguished within a cell. For example:
(1) One cell defining SSB is used for user access with common coverage, supports directional beam scanning, and covers the terminals of the whole cell;
(2) And (3) using one cell defining SSB as user access for enhancing coverage, transmitting beams in the same direction by using a plurality of SSB indexes (indexes) in one SSB period, and enhancing a certain beam direction through energy accumulation.
Considering the coverage enhancement described above, different BWP means different coverage for the terminal. Therefore, the terminal also needs to measure the channel quality of BWP of other coverage levels during the movement so that the terminal can switch between different coverage levels within the cell.
When the terminal operates on the normal BWP, the base station can feed back the channel quality of the terminal on each beam to the base station by configuring a channel state information Reference Signal (CSI-RS) CSI resource corresponding to the normal beam scan on the BWP for measurement and reporting of the measured value, and since the base station knows which beams are repeatedly enhanced, the base station can obtain the channel quality of the enhanced beam by processing the measured value of the terminal of the corresponding beam, thereby judging whether the terminal needs to be switched to the BWP with enhanced coverage.
However, according to the existing measurement configuration, the measurement results are reported to 4 at most, if no enhancement is performed, the terminal cannot identify the measurement resource corresponding to the enhanced BWP, and the reported result may not include the beam corresponding to the enhanced coverage.
As shown in fig. 1, beam 3 is an enhanced beam, and when working on a BWP covered normally, if the enhancement effect of beam 3 is not considered, the reported measurement may not include the measurement of beam 3 because of the quality of reporting 4 beams at most, although beam 3 may be better after enhancement.

Referring to fig. 3, an embodiment of the present invention provides a method for measuring reference signal configuration, where an execution body of the method is a network device, and the method includes step 301 and step 302.
Step 301: transmitting CSI reporting configuration and/or CSI resource configuration to a terminal;
step 302: and indicating to the terminal that the CSI reporting configuration and/or the CSI resource configuration corresponds to the measurement of coverage enhancement or to repeated transmission of the CSI resource.
In the embodiment of the present invention, indicating to the terminal that the CSI reporting configuration and/or the CSI resource configuration of the terminal corresponds to a measurement of coverage enhancement includes: and indicating the terminal to report after compensating based on the measurement value obtained by the CSI reporting configuration and/or the CSI resource configuration, so that the base station can obtain the channel quality of the enhanced beam. Compensation here means that, in comparison with reporting the measurement directly (this measurement may be a measurement processed by layer 1, layer 3, a reported value corresponding to the R15 version or R16 version of NR), the measurement needs to be adjusted, the adjusted value being obtained based on the indicated number of repetitions or offset value.
In the embodiment of the present invention, indicating to the terminal that the CSI reporting configuration and/or the CSI resource configuration corresponds to repeated transmission of CSI resources includes: and indicating the measured value (the measured value can be the measured value processed by the layer 1 and the layer 3 and corresponds to the reported value of the R15 version or the R16 version of NR) obtained by the terminal based on the CSI reporting configuration and/or the CSI resource configuration to the terminal, adjusting the measured value according to the repetition number or the offset, and reporting the adjusted measured value, so that the base station can obtain the channel quality of the enhanced beam.
The coverage enhancement indicates that coverage is extended, which may be said to correspond to measurement of the time-frequency domain resources after coverage extension, or if implementation of coverage enhancement is defined as a coverage enhancement mode or coverage extension mode, the CSI reporting configuration and/or the CSI resource configuration are indicated to the terminal to correspond to measurement of the coverage enhancement mode or coverage extension mode, or to repeated transmission of the CSI resources.
In the embodiment of the present invention, the above step 302 may be implemented by the following manner:
mode 1: and sending an indication signaling to the terminal, wherein the indication signaling indicates that the CSI reporting configuration and/or the CSI resource configuration corresponds to the measurement of coverage enhancement or the repeated sending of the CSI resource.
Optionally, the indication signaling indicates that the CSI report configuration ID, the CSI resource configuration ID, or the CSI resource ID corresponds to a measurement of coverage enhancement or to repeated transmission of the CSI resource.
In some implementations, the CSI resource ID includes an ID of the resource used for beam measurement and reporting, for example: non-zero power channel state information reference signal resource set identification (NZP-CSI-RS-ResourceSetId), channel state information synchronization signal block resource set identification (CSI-SSB-ResourceSetId), non-zero power channel state information reference signal resource identification (NZP-CSI-RS-ResourceId), synchronization signal block Index (SSB-Index).
NR beam management is performed based on channel state information (Channel State Information, CSI) reporting (report), and the measurement is performed by measuring resources of an NZP-CSI-RS resource set (resource set), and the channel quality of the terminal is obtained by reporting the measurement values, thereby performing beam management of the terminal. The network configures parameters of CSI reporting and also configures parameters of CSI resources, and establishes an association between the parameters of CSI reporting and the parameters of CSI resources. I.e. for each CSI report, the CSI measurement resources it uses are configured.
Optionally, the indication signaling further indicates the CSI report configuration ID, the CSI resource configuration ID, or an offset of a measurement value corresponding to the CSI resource ID, or the repetition number of repeated transmission of the CSI resource.
For example, if the measured value measured based on the CSI resource is X, the measured value needs to be compensated, and the measured value after compensation is reported. For example, the compensated measurement value is X' =x+offset; or assuming that the number of repeated transmissions is N, the compensated measurement value is X' =x+f (N), where f (N) represents a function of N.
Mode 2: and indicating the CSI reporting configuration and/or the CSI resource configuration to the terminal through the CSI reporting configuration and/or the CSI resource configuration, wherein the CSI reporting configuration and/or the CSI resource configuration corresponds to the measurement of coverage enhancement or the repeated transmission of the CSI resource.
Compared with the mode 1, in the mode 2, through the CSI reporting configuration and/or the CSI resource configuration indication, the indication signaling on the network side can be saved.
In some embodiments, the CSI reporting configuration includes: CSI reporting amount configuration, the CSI resource configuration includes: configuration of CSI resource sets;
the set of CSI resources corresponds to a measurement of coverage enhancement or to repeated transmission of CSI resources if the set of CSI resources is configured to be repetition on, the CSI reporting amount is configured to be channel state information reference signal resource indicator (CSI-RS resource indicator, CRI) reference signal received power (Reference Signal Receiving Power, RSRP). Further, the repetition number of the CSI resource indicates the repetition number of repeated transmission of the CSI resource.
In the prior art, when the CSI-RS resource set includes "repetition", it indicates whether the terminal can assume that all reference signals in the CSI-RS resource set use the same spatial filtering, and when repetition is set to on (not), it indicates that all reference signals in the CSI-RS resource set use the same spatial filtering, at this time, the terminal can perform beam adjustment on the downlink receiving side, and determine the best receiving beam by scanning and receiving using different receiving beams.
Since the terminal receives the behavior of the terminal side and does not need to participate in the base station, reporting is not needed, and CRI reporting is not performed when repetition is set to on; and the scheme uses the CSI reporting quantity to configure to report the RSRP, so that the terminal can recognize that the configuration corresponds to the measurement of coverage enhancement and report.
Mode 3: and indicating the CSI reporting configuration and/or the CSI resource configuration to the terminal through the configured antenna port number, wherein the CSI reporting configuration and/or the CSI resource configuration corresponds to the measurement of coverage enhancement or the repeated transmission of the CSI resource.
In some embodiments, the CSI reporting configuration includes: CSI reporting amount configuration, the CSI resource configuration includes: channel state information Reference Signal (Channel State Information-Reference Signal, CSI-RS) resource allocation;
and if the CSI reporting amount is configured as CRI RSRP and the NZP-CSI-RS resource set contained in the CSI-RS resource configuration is configured to be repeated, indicating that the CSI-RS resource configuration corresponds to measurement of coverage enhancement or repeated transmission of the CSI resources by configuring the number of antenna ports to be more than 2.
The existing antenna ports can only be 1 or 2 when the CSI reporting amount is configured as CRI-RSRP. According to the embodiment of the invention, by adding the antenna ports, and the corresponding relation exists between the number of the antenna ports and the repetition number, for example, the antenna ports are configured to be 8 ports, which indicates that 8 repeated transmissions exist in a measurement signal, RSRP can be calculated and reported based on repeated measurement; or configured as 8 ports, indicating 4 repetitions, each 2 ports corresponding to a single transmission. The configuration can support the beam scanning of the transmitting end, and normal transmitting end scanning operation when the CSI resources are configured to repetition is not affected.
In the embodiment of the invention, the terminal is instructed to perform coverage enhancement measurement on the corresponding CSI resources, so that the terminal can consider the coverage enhancement of the beams during measurement, and the feedback channel measurement quality can be matched with the channel quality of each beam, thereby facilitating the reference of resource allocation on the network side.
Referring to fig. 4, the embodiment of the present invention further provides a method for measuring reference signal configuration, where an execution body of the method may be a terminal, and the method includes step 401 and step 402.
Step 401: acquiring CSI reporting configuration and/or CSI resource configuration configured by a network side;
step 402: and acquiring the CSI reporting configuration and/or the CSI resource configuration indicated by the network side, wherein the CSI reporting configuration and/or the CSI resource configuration corresponds to the measurement of coverage enhancement or corresponds to repeated transmission of the CSI resource.
In the embodiment of the present invention, the CSI reporting configuration and/or CSI resource configuration corresponds to a measurement of coverage enhancement, and includes: and compensating and reporting the measurement value based on the CSI reporting configuration and/or the CSI resource configuration, so that the base station can obtain the channel quality of the enhanced beam.
In the embodiment of the present invention, the CSI reporting configuration and/or CSI resource configuration corresponds to repeated transmission of CSI resources, and includes: and the terminal adjusts the measured value based on the CSI reporting configuration and/or the CSI resource configuration, and reports the adjusted measured value based on the repetition number or the offset, so that the base station can obtain the channel quality of the enhanced beam.
In an embodiment of the present invention, step 402 may be implemented by:
mode 1: and receiving indication signaling from the network side, wherein the indication signaling indicates that the CSI reporting configuration and/or the CSI resource configuration corresponds to the measurement of coverage enhancement or the repeated transmission of the CSI resource.
Optionally, the indication signaling indicates that the CSI report configuration ID, the CSI resource configuration ID, or the CSI resource ID corresponds to a measurement of coverage enhancement or to repeated transmission of the CSI resource.
Optionally, the CSI reporting configuration includes a CSI reporting configuration identifier ID; the CSI resource configuration includes: CSI resource configuration ID and/or CSI resource ID;
the indication signaling may further indicate that the CSI reporting configuration ID, the CSI resource configuration ID, or the CSI resource ID corresponds to one or more of the following: coverage enhanced measurements; repeated transmission of CSI resources; offset of the measured value; number of repetitions of repeated transmission.
In some implementations, the CSI resource ID includes an ID of the resource used for beam measurement and reporting, for example: NZP-CSI-RS-ResourceSetId, CSI-SSB-ResourceSetId, NZP-CSI-RS-resource eid, SSB-Index.
Optionally, the indication signaling further indicates the CSI report configuration ID, the CSI resource configuration ID, or an offset of a measurement value corresponding to the CSI resource ID, or the repetition number of repeated transmission of the CSI resource.
Mode 2: and acquiring the CSI reporting configuration and/or the CSI resource configuration indicated by the network side according to the CSI reporting configuration and/or the CSI resource configuration, wherein the CSI reporting configuration and/or the CSI resource configuration corresponds to coverage enhancement measurement or repeated transmission of the CSI resource.
Mode 3: acquiring the number of antenna ports configured by the network side; and acquiring the CSI reporting configuration and/or the CSI resource configuration indicated by the network side according to the number of the antenna ports, wherein the CSI reporting configuration and/or the CSI resource configuration corresponds to the measurement of coverage enhancement or the repeated transmission of the CSI resource.
In the embodiment of the invention, the terminal is instructed to perform coverage enhancement measurement on the corresponding CSI resources, so that the terminal can consider the coverage enhancement of the beams during measurement, and the feedback channel measurement quality can be matched with the channel quality of each beam, thereby facilitating the reference of resource allocation on the network side.
Illustratively, taking the network device as a reference, the base station performs CSI reporting configuration and/or CSI resource configuration, and indicates to the terminal that the CSI reporting configuration and/or CSI resource configuration corresponds to enhanced coverage or repeated transmission of CSI resources.
The indication mode may include: mode 1, mode 2, and mode 3.
Mode 1: indicating to the terminal its CSI resource configuration ID (CSI-ResourceConfigId), or CSI reporting configuration ID (CSI-ReportConfigId), or CSI resource ID (e.g. non-zero power channel state information reference signal resource set identity (NZP-CSI-RS-resourcesid), channel state information synchronization signal block resource set identity (CSI-SSB-resourcesid), non-zero power channel state information reference signal resource identity (NZP-CSI-RS-ResourceId), synchronization signal block Index (SSB-Index)) corresponds to enhanced coverage or repeated transmission of CSI resources;
Optionally, the offset value or the corresponding repetition number that needs to be increased is further indicated, so that the terminal can adjust the measurement value based on the measurement value.
When the current measurement report of the terminal is associated to the CSI resource configuration ID corresponding to the enhanced beam, or the CSI report ID or the CSI resource ID, the terminal adjusts the measured value according to the indicated offset value or the repetition number and reports the adjusted measured value, so that the base station can obtain the channel quality of the enhanced beam.
Mode 2: by configuring the corresponding channel state information resource Set (CSI-resource Set) to "repetition" while configuring the reporting amount (reportquality) to be the channel state information reference signal received power (cri-RSRP), it is indicated that the CSI-resource Set corresponds to enhanced coverage or repeated transmission of CSI resources.
When the CSI-RS resource set includes "repetition", it indicates whether the terminal can assume that all reference signals in the CSI-RS resource set employ the same spatial filtering, and when repetition is set to on, it indicates that all reference signals in the CSI-RS resource set employ the same spatial filtering, at this time, the terminal can perform beam (beam) adjustment on the downlink receiving side, and determine the best receiving beam by scanning and receiving using different receiving beams.
It can be understood that, since the terminal determines that the received beam is a behavior of the terminal side, the base station is not required to participate, and thus, reporting is not required, so CRI reporting is not performed when repetition is set to on;
the CSI-resource Set is configured into a repetition, and meanwhile, the reportquality is configured to be cri-RSRP, so that the terminal needs to measure and report the RSRP value of repeated transmission according to repeated CSI-RS resources, the channel quality of the enhanced beam can be obtained, and the number of resources of the repetition indicates the enhanced repetition times.
Mode 3: indicating the measurement of the enhanced beam by configuring the port number;
when the CSI-RS is configured to carry out L1-RSRP measurement, only 1 port or 2 ports can be configured at most;
and if the reporting amount in the CSI reporting configuration is set to be CRI RSRP or null, the CSI resource configuration comprises a NZP-CSI-RS resource set, and the same antenna port number is configured for a plurality of CSI-RS resources in the NZP-CSI-RS resource set.
When the reportquality is configured as 'cri-RSRP', and the repetition is configured, the number of antenna ports is configured to be more than 2, so that the current CSI-RS resource can be indicated to correspond to the enhanced coverage;
for example, configured as 8 ports, indicating 8 repetitions, RSRP may be calculated and reported based on the repeated measurements;
As another example, configured as 8 ports, indicating 4 repetitions, each 2 ports corresponds to a single transmission.
It will be appreciated that mode 3 may support beam scanning at the transmitting end as compared to mode 2.
In order to reduce the complexity of terminal measurement, the triggering conditions of measurement and reporting in the foregoing modes 1, 2 and 3 may be preset, for example, when the channel quality of the current beam is worse than a certain threshold, measurement reporting of the enhanced beam may be triggered as required.
