New Radio (NR) introduces beam scanning to enhance coverage, enabling coverage over longer distances by using directional, narrower Synchronization Signal and PBCH block (SSB) beams.

Detailed Description
From standard design to network planning, the design is performed according to the coverage range of relatively equal cells, but in actual network deployment, some scenes always exist, which results in short coverage in some directions. For example, under the coverage of the same cell, the propagation in one direction experiences large attenuation due to the dense trees or buildings, so that the coverage in the direction is poor and the user rate is low.
Therefore, a hierarchical coverage design scheme may be considered, which implements multiple candidate initial (initial) BWP accesses by transmitting multiple cell defining SSBs in the same cell based on a fractional Bandwidth Part (BWP) structure. While supporting different coverage levels on different initial BWPs. It is called as layered coverage, i.e. coverage of different levels is differentiated within one cell. For example:
(1) a cell defining SSB is used for making user access of common coverage, supporting directional beam scanning and covering terminals of the whole cell;
(2) an SSB of one cell defining is used for user access for enhancing coverage, a plurality of SSB indexes (indexes) in one SSB period transmit beams in the same direction, and the enhancement of a certain beam direction is realized through energy accumulation.
Considering the coverage enhancement introduced above, different BWPs mean different coverage for the terminal. Therefore, the terminal needs to measure the channel quality of BWP of other coverage levels during the moving process, so that the terminal can switch between different coverage levels in the cell.
When the terminal works on a common BWP, Channel State Information-Reference Signal (CSI-RS) CSI resources corresponding to common beam scanning are configured on the BWP for measurement and measurement value reporting, the Channel quality of the terminal on each beam can be fed back to the base station, and the base station can acquire the Channel quality of an enhanced beam by processing the terminal measurement value of the corresponding beam because the base station grasps which beams are repeatedly enhanced, so that whether the terminal needs to be switched to the BWP with enhanced coverage or not is judged.
However, according to the existing measurement configuration, the maximum number of measurement results is reported to 4, and 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, the beam 3 is an enhanced beam, and when operating on a normal coverage BWP, if the measurement value does not consider the enhancement effect of the beam 3, the reported measurement value may not include the measurement value of the beam 3 due to the quality of reporting 4 beams at most, although it may be better after enhancing the beam 3.

In practical applications, the connections between the above devices may be wireless connections, and fig. 2 is illustrated with solid lines for convenience and intuition of the connection relationships between the devices.
The network device 20 provided in the embodiment of the present invention may be a base station, which may be a commonly used base station, an evolved node base station (eNB), or a network device in a 5G system (e.g., a next generation base station (gNB) or a Transmission and Reception Point (TRP)).

Referring to fig. 3, an embodiment of the present invention provides a method for measuring reference signal configuration, where an execution subject of the method is a network device, and the method includes steps 301 and 302.
Step 301: sending CSI reporting configuration and/or CSI resource configuration to a terminal;
step 302: and indicating the CSI reporting configuration and/or the CSI resource configuration to the terminal to correspond to the measurement of coverage enhancement or to correspond to the 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 corresponds to coverage enhancement measurement includes: and indicating the terminal to report after compensating the measured value obtained by the terminal 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. Compensation here means that the measured value needs to be adjusted, which is obtained based on the indicated repetition number or offset value, compared to directly reporting the measured value (this measured value may be a measured value processed by layer 1, layer 3, a reported value corresponding to the R15 version or R16 version of NR).
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 terminal to obtain a measurement value (the measurement value can be a measurement value processed by a layer 1 and a layer 3 and a report value corresponding to an R15 version or an R16 version of NR) based on the CSI report configuration and/or the CSI resource configuration, adjusting the measurement value by combining the repetition number or the offset, and reporting the adjusted measurement value, so that the base station can obtain the channel quality of the enhanced beam.
The coverage enhancement indicates that the coverage is extended, or in other words, the coverage enhancement indicates measurement of time-frequency domain resources after the coverage extension, or if the implementation of the coverage enhancement is defined as a coverage enhancement mode or a coverage extension mode, the CSI reporting configuration and/or the CSI resource configuration indicates measurement corresponding to the coverage enhancement mode or the coverage extension mode, or indicates repeated transmission corresponding to CSI resources to the terminal.
In an embodiment of the present invention, the step 302 may be implemented as follows:
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 coverage enhancement measurement or repeated sending of CSI resources.
Optionally, the indication signaling indicates that the CSI reporting configuration ID, the CSI resource configuration ID, or the CSI resource ID corresponds to coverage enhanced measurement or to repeated transmission of CSI resources.
In some embodiments, the CSI resource ID includes an ID of a resource used for beam measurement and reporting, for example: a non-zero power channel state information reference signal resource set identification (NZP-CSI-RS-ResourceSetId), a channel state information synchronization signal block resource set identification (CSI-SSB-ResourceSetId), a non-zero power channel state information reference signal resource identification (NZP-CSI-RS-ResourceId), a synchronization signal block Index (SSB-Index).
NR beam management is performed based on Channel State Information (CSI) reporting (report), and by measuring resources of a NZP-CSI-RS resource set (resource set), reporting the measured values to obtain Channel quality of a terminal, thereby performing beam management of the terminal. The network configures parameters for CSI reporting and also configures parameters for CSI resources, and establishes association between the two in the configuration for CSI reporting. I.e. for each CSI report, the CSI measurement resources it uses are configured.
Optionally, the indication signaling further indicates the CSI reporting configuration ID, the CSI resource configuration ID, or an offset of a measurement value corresponding to the CSI resource ID, or a repetition number of repeated sending 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 measurement value is reported based on the compensated measured value. 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 corresponding to coverage enhancement measurement or repeated transmission of CSI resources through the CSI reporting configuration and/or the CSI resource configuration.
Compared with the mode 1, in the mode 2, the indication signaling of the network side can be saved through the CSI reporting configuration and/or the CSI resource configuration indication.
In some embodiments, the CSI reporting configuration comprises: and configuring CSI reporting quantity, wherein the CSI resource configuration comprises: configuring a CSI resource set;
the CSI resource set corresponds to a coverage enhanced measurement or to a repeated transmission of CSI resources if the CSI resource set is configured to be repeatedly on (repetition on) and the CSI reported amount is configured to be a channel state information Reference Signal resource indicator (CRI) Reference Signal Received Power (RSRP). Further, the number of repetitions of the CSI resource indicates the number of repetitions of the repeated transmission of the CSI resource.
In the prior art, when a CSI-RS resource set includes "repetition", it indicates whether a terminal may assume that all reference signals in the CSI-RS resource set employ the same spatial filtering, and when repetition is set to be on (on), it indicates that all reference signals in the CSI-RS resource set employ the same spatial filtering, at this time, the terminal may perform beam adjustment on a downlink receiving side, and scan and receive by using different receiving beams, and determine an optimal receiving beam.
Because the terminal receiving beam is the behavior of the terminal side, and does not need the participation of a base station, the reporting is not needed, and the CRI reporting is not carried out when the repetition is set to be on; in the scheme, the CSI reported quantity is configured to report the RSRP, so that the terminal can identify that the configuration corresponds to the measurement of coverage enhancement and report the measurement.
Mode 3: and indicating the CSI reporting configuration and/or the CSI resource configuration corresponding to coverage enhancement measurement or repeated transmission corresponding to CSI resources to the terminal through the configured number of the antenna ports.
In some embodiments, the CSI reporting configuration comprises: and configuring CSI reporting quantity, wherein the CSI resource configuration comprises: channel State Information-Reference Signal (CSI-RS) resource allocation;
and if the CSI reported quantity is configured as CRI RSRP and the NZP-CSI-RS resource set contained in the CSI-RS resource configuration is configured with repetition, indicating that the CSI-RS resource configuration corresponds to coverage enhancement measurement or repeated transmission of CSI resources by configuring the number of the antenna ports to be a number larger than 2.
When the CSI report volume is configured as CRI-RSRP, the configured antenna port can only be 1 or 2. In the embodiment of the invention, by adding the antenna ports, the number of the antenna ports and the number of the repeated times have a corresponding relation, for example, the antenna ports are configured to be 8 ports, which indicates that the measurement signal has 8 times of repeated transmission, and the RSRP can be calculated and reported based on the repeated measurement; or configured as 8 ports, indicating 4 repetitions, with each 2 ports corresponding to a single transmission. The configuration can support beam scanning of the transmitting end, and normal transmitting end scanning operation when the CSI resource is configured to be repeat is not influenced.
In the embodiment of the invention, the terminal is instructed to measure the CSI resources corresponding to the coverage enhancement, 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 configuration on the network side.
Referring to fig. 4, an embodiment of the present invention further provides a method for measuring reference signal configuration, where an execution subject of the method may be a terminal, and the method includes steps 401 and 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 CSI resource configuration indicated by the network side, wherein the CSI reporting configuration and/or CSI resource configuration corresponds to coverage enhancement measurement or repeated transmission of CSI resources.
In this embodiment of the present invention, the CSI reporting configuration and/or CSI resource configuration corresponds to coverage enhancement measurement, and includes: and reporting the measurement value obtained based on the CSI reporting configuration and/or the CSI resource configuration after compensation, so that the base station can obtain the channel quality of the enhanced beam.
In the embodiment of the present invention, the repeatedly sending of the CSI reporting configuration and/or the CSI resource configuration corresponding to the CSI resource includes: and the terminal adjusts the measurement value based on the CSI reporting configuration and/or the CSI resource configuration, and reports the adjusted measurement value, so that the base station can obtain the channel quality of the enhanced beam.
In this embodiment of the present invention, step 402 can be implemented as follows:
mode 1: and receiving an indication signaling from the network side, wherein the indication signaling indicates that the CSI reporting configuration and/or the CSI resource configuration corresponds to coverage enhancement measurement or repeated transmission of CSI resources.
Optionally, the indication signaling indicates that the CSI reporting configuration ID, the CSI resource configuration ID, or the CSI resource ID corresponds to coverage enhanced measurement or to repeated transmission of CSI resources.
Optionally, the CSI reporting configuration includes a CSI reporting configuration identifier ID; the CSI resource configuration comprises: a CSI resource configuration ID and/or a CSI resource ID;
the indication signaling may further indicate that the CSI reporting configuration identifier ID, the CSI resource configuration ID, or the CSI resource ID corresponds to one or more of the following: measurement of coverage enhancement; repeated transmission of CSI resources; an offset of the measurement; the number of repetitions of the repeated transmission.
In some embodiments, the CSI resource ID includes an ID of a resource used for beam measurement and reporting, for example: NZP-CSI-RS-ResourceSetId, CSI-SSB-ResourceSetId, NZP-CSI-RS-ResourceId, SSB-Index.
Optionally, the indication signaling further indicates the CSI reporting configuration ID, the CSI resource configuration ID, or an offset of a measurement value corresponding to the CSI resource ID, or a repetition number of repeated sending of the CSI resource.
Mode 2: and acquiring the CSI reporting configuration and/or the CSI resource configuration indicated by the network side, which corresponds to coverage enhancement measurement or repeated transmission of CSI resources.
Mode 3: acquiring the number of antenna ports configured on the network side; and acquiring the CSI reporting configuration and/or CSI resource configuration indicated by the network side corresponding to coverage enhancement measurement or repeated transmission of CSI resources according to the number of the antenna ports.
In the embodiment of the invention, the terminal is instructed to measure the CSI resources corresponding to the coverage enhancement, 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 configuration on the network side.
Illustratively, taking network equipment 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 the CSI resource configuration corresponds to enhanced coverage or repeated transmission of CSI resources.
The indicating mode may include: mode 1, mode 2, and mode 3.
Mode 1: indicating a CSI resource configuration ID (CSI-ResourceConfigId) or a CSI reporting configuration ID (CSI-ReportConfigId) or a CSI resource ID (e.g., a non-zero power channel state information reference signal resource set identifier (NZP-CSI-RS-ResourceSetId), a channel state information synchronization signal block resource set identifier (CSI-SSB-ResourceSetId), a non-zero power channel state information reference signal resource identifier (NZP-CSI-RS-ResourceId), a synchronization signal block Index (SSB-Index)) to the terminal by an indication signaling (e.g., RRC signaling) corresponding to the enhanced coverage or the repeated transmission of CSI resources;
optionally, a corresponding offset value that needs to be increased or a corresponding number of repetitions is further indicated, so that the terminal can make an adjustment of the measurement value on the basis of the measurement value.
When the current measurement report of the terminal is associated with the CSI resource configuration ID corresponding to the enhanced beam, or the CSI report ID or the CSI resource ID, the terminal adjusts the measurement value according to the indicated offset value or the repetition times, and reports the adjusted measurement value, so that the base station can obtain the channel quality of the enhanced beam.
Mode 2: by configuring a corresponding Set of channel state information resources (CSI-resource Set) as "repetition on" while configuring a reporting quantity (reporting quantity) as a channel state information reference signal received power (cri-RSRP), it indicates that the CSI-resource Set corresponds to enhanced coverage or repeated transmission of CSI resources.
When the CSI-RS resource set comprises the "repetition", whether the terminal can assume that all reference signals in the CSI-RS resource set adopt the same spatial filtering is indicated, and when the repetition is set to be on, all reference signals in the CSI-RS resource set adopt the same spatial filtering is indicated, at this time, the terminal can perform beam (beam) adjustment on a downlink receiving side, and the optimal receiving beam is determined by scanning and receiving by using different receiving beams.
It can be understood that, since the terminal determines that the receiving beam is the behavior of the terminal side, and does not need to participate in the base station, the reporting is not needed, and therefore, when the repetition is set to be on, the CRI reporting is not performed;
the CSI-resource Set is configured to be 'repetition on', meanwhile, the reporting quantity is configured to be cri-RSRP, the fact that the terminal needs to measure the RSRP value of repeated transmission according to repeated CSI-RS resources and report the RSRP value shows that the channel quality of the enhanced beam can be obtained, and the number of the resources of repetition shows the number of the enhanced repetition times.
Mode 3: indicating a 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 quantity in the CSI reporting configuration is set as CRI RSRP or null, the CSI resource configuration comprises an NZP-CSI-RS resource set, and the same number of antenna ports is configured for a plurality of CSI-RS resources in the NZP-CSI-RS resource set.
When the reportQuantity is configured as 'cri-RSRP' and the repetition is configured, by configuring the number of antenna ports as a number greater than 2, it can be indicated that the current CSI-RS resource corresponds to enhanced coverage;
for example, the RSRP is configured to be 8 ports, which indicates that there are 8 repetitions, and RSRP may be calculated and reported based on the repeated measurements;
for another example, an 8 port configuration indicates 4 repetitions, with each 2 ports corresponding to a single transmission.
It can be understood that the mode 3 may support beam scanning of the transmitting end compared to the mode 2.
In order to reduce the complexity of terminal measurement, the conditions for triggering measurement and reporting in the above-mentioned modes 1, 2, and 3 may be preset, for example, when the channel quality of the current beam is worse than a certain threshold, the measurement and reporting of the enhanced beam may be triggered as needed.
