Description
Technical Field
The present invention relates to the field of signal transmission, and in particular, to a method, an apparatus, a device, and a storage medium for dynamically configuring signal resources.
Background
In the 5G system, CSI-RS (Channel state information-Reference Signal, channel state information Reference Signal resource) for downlink channel measurement is classified into a UE (User Equipment) level and a cell level.
UE-level CSI-RS allocates a proprietary CSI-RS resource to each accessed terminal, and has the advantages that the beam of the CSI-RS points to user equipment (terminal) and the gain of beam forming is high; the disadvantage is the large resource overhead.
The cell-level CSI-RS is that all terminals in one cell share CSI-RS resources, and the CSI-RS beam pointing is fixed and does not point to a specific terminal. The method has the advantages of saving cost; the disadvantage is that the beam of the CSI-RS is a broad beam and the beamforming gain is lower than the CSI-RS resources at the UE level.
At present, the cell-level CSI-RS resources are generally statically allocated to the terminal, if the terminal capability is limited, and the number of the cell-level CSI-RS resources supported to be configured is smaller than the number of the resources actually used by the network side cell, the base station can only configure the CSI-RS resources for the terminal according to the terminal capability, namely, configure part of the cell-level CSI-RS resources for the terminal; the following problems are: if the terminal moves to the coverage of the beam corresponding to the CSI-RS resource which is not allocated to the terminal, the terminal still measures the beam corresponding to the CSI-RS resource allocated to the terminal to report the channel quality, so that the measured channel quality and the actual channel quality are greatly different. As shown in fig. 1, a CSI-RS beam 1 and a CSI-RS beam 2 are allocated to a terminal 100, and the terminal 100 moves to the coverage of a CSI-RS beam 4, at this time, the terminal 100 still measures the corresponding beams of the CSI-RS beam 1 and the CSI-RS beam 2 allocated thereto to report the channel quality, which tends to cause a large difference between the measured channel quality and the actual channel quality.
Therefore, how to realize signal resource allocation so as to ensure that the terminal is positioned in the coverage range of the allocated signal resource and avoid the situation that the difference between the channel quality measured by the terminal and the actual channel quality is large is a technical problem to be solved by the technicians in the field.

Detailed Description
Example embodiments will now be described more fully with reference to the accompanying drawings. However, the example embodiments may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the concept of the example embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and thus a repetitive description thereof will be omitted.
Referring to fig. 2, fig. 2 is a flow chart of one embodiment of a method of dynamically configuring signal resources of the present invention. The embodiment of the invention provides a method for dynamically configuring signal resources, which comprises the following steps:
step S210: and allocating the first signal resource to the terminal.
Specifically, the first signal resource is a channel state information reference signal (CSI-RS) resource.
Step S220: and receiving the first reference signal receiving power of the first signal resource and the second reference signal receiving power of the second signal resource reported by the terminal.
Specifically, the second signal resource is a synchronization signal and a physical broadcast signal reference signal (SSB) resource. SSB is a synchronization signal and PBCH block (Synchronization Signal and PBCH block, SSB) and is composed of a primary synchronization signal (Primary Synchronization Signals, PSS), a secondary synchronization signal (Secondary Synchronization Signals, abbreviated SSS), and a physical broadcast channel (physical broadcast channel, PBCH).
RSRP (Reference Signal Receiving Power, reference signal received power) is one of the key parameters that can represent radio signal strength and physical layer measurement requirements in an LTE network, and is the average of the signal power received on all REs (resource elements) that carry reference signals within a certain symbol.
Step S230: and judging whether the difference value between the first reference signal receiving power and the second reference signal receiving power is larger than a threshold value.
In particular, the threshold value may be set as required, for example, the threshold value may be adjusted and optimized for different cells, which is not limited in this application.
If yes in step S230, step S240 is executed: and acquiring a second beam identifier of at least one second signal resource with highest second reference signal receiving power reported by the terminal.
Specifically, in some embodiments, the number of second beam identifications obtained in step S240 is two. The present application is not limited in this regard.
Step S250: and judging whether the terminal is in the coverage area of the first beam of the unassigned first signal resource according to the second beam identifier.
Specifically, the network side may determine the coverage area of each beam (SSB/CSI-RS/service beam, etc.) and the correspondence between different types of beams according to the information such as the beam pattern and the antenna pattern.
Step S250 may include, for example: acquiring coverage area of a second beam associated with the second beam identifier; acquiring coverage areas of the first beams; and judging whether the terminal is in the coverage area of the first beam of the unassigned first signal resource according to the coverage relation between the coverage area of the second beam associated with the second beam identifier and the coverage area of the first beam. Thereby, the judgment of the coverage relation of the coverage can be realized.
If the determination in step S250 is yes, step S260 is executed: and allocating a first signal resource covering the current position of the terminal to the terminal.
Specifically, since the maximum support number of the terminal is limited, when step S260 is performed, a step of deallocating the first signal resource allocated to the terminal from the terminal may be further performed, thereby satisfying the maximum support number of the terminal.
The invention triggers the acquisition of the second beam identifier of at least one second signal resource with the highest second reference signal receiving power by judging whether the difference value between the first reference signal receiving power and the second reference signal receiving power is larger than a threshold value, so as to judge whether the terminal is in the coverage area of the first beam of the unassigned first signal resource according to the second beam identifier, and realize the reassignment of the resource based on the judging result. Therefore, on one hand, the throughput rate of the terminal with limited capacity can be improved; on the other hand, the first signal resource of the cell level can be dynamically allocated according to the terminal position, so that the accuracy of the downlink channel quality measurement of the terminal with limited capacity is improved; in another aspect, the influence on the load of the network side equipment is small, the difference value between the first reference signal received power and the second reference signal received power is firstly used for initial judgment, and after the initial judgment is successful, the first signal beam and the second signal beam are compared to determine the current position of the terminal.
Referring now to fig. 3, fig. 3 is a flow chart of another embodiment of a method of dynamically configuring signal resources of the present invention.
Step S310: and receiving the maximum support number of the first signal resource reported by the terminal.
Step S320: judging whether the maximum support number is smaller than the number of first signal resources of a cell where the terminal is located;
if the determination in step S320 is negative, step S330 is executed: and distributing all first signal resources of the cell where the terminal is located to the terminal. Step S340 to step S390 are not performed.
If the determination in step S320 is yes, step S340 is executed: and distributing first signal resources to the terminal according to the maximum support number.
Step S350: and receiving the first reference signal receiving power of the first signal resource and the second reference signal receiving power of the second signal resource reported by the terminal.
Step S360: and judging whether the difference value between the first reference signal receiving power and the second reference signal receiving power is larger than a threshold value.
If yes in step S360, step S370 is executed: and acquiring a second beam identifier of at least one second signal resource with highest second reference signal receiving power reported by the terminal.
Step S380: and judging whether the terminal is in the coverage area of the first beam of the unassigned first signal resource according to the second beam identifier.
If yes in step S380, step S390 is executed: and allocating a first signal resource covering the current position of the terminal to the terminal.
Referring now to fig. 4, fig. 4 is a schematic diagram of one embodiment of the coverage of a terminal by a first signal beam and a second signal beam of the present invention. In fig. 4, there are 4 CSI-RS resources (first signal resources) at the cell level, but the terminal 400 is capable of supporting configuration of only 2 CSI-RS resources, so that the base station allocates CSI-RS resources 1 and 2 (first signal beam 1 and first signal beam 2) at the cell center to the terminal. When the terminal 400 moves to the position in the figure, the base station detects that the difference between the RSRP of the SSB (second signal resource) and the RSRP of the CSI-RS (first signal resource) reported by the terminal exceeds a threshold value. Then, the base station determines that the terminal is currently under the beam coverage corresponding to the CSI-RS resource 4 not allocated to the terminal according to the best SSBRI (second beam identification) =6 (second signal beam 6) of the RSRP and the second best SSBRI (second beam identification) =7 (second signal beam 7) of the SSBRI. The base station reallocates the CSI-RS resources to the terminal, and the new resources include the CSI-RS resources 4, thereby ensuring that the terminal is always under the beam coverage corresponding to the allocated CSI-RS resources.
In the application, the network side can determine the coverage area of each beam (SSB/CSI-RS/service beam, etc.) and the corresponding relation between different types of beams according to the information such as the beam pattern and the antenna pattern.
By letting the terminal with limited capability report the SSB beam IDs (SSBRI) with the best RSRP, the network side can determine which cell-level CSI-RS resource the terminal is under beam coverage according to the 2 SSB beam IDs. For example, the network side may set the terminal to report one or two CRI/SSBRI in groupBasedBeamReporting field in CSI-ReportConfig IE in RRC message.
When detecting that the difference value between the RSRP of the SSB reported by the terminal and the RSRP of the CSI-RS is greater than a certain threshold value, the network side judges that the terminal is possibly under the beam coverage corresponding to the non-allocated CSI-RS resource. And then the network side determines which CSI-RS resource beam the terminal currently locates under coverage by 2 best SSB beam IDs reported by the terminal. If the cell-level CSI-RS resources covering the current position of the terminal are not allocated to the terminal, the network side reallocates the CSI-RS resources to the terminal, and allocates the CSI-RS resources covering the current position of the terminal to the terminal. Therefore, the cell-level CSI-RS resources can be dynamically allocated according to the position of the terminal, the terminal is ensured to be always under the beam coverage corresponding to the allocated CSI-RS resources, and the accuracy of channel measurement is ensured.
In a specific application, a network side uses a cell-level CSI-RS to measure a downlink channel, and the number of CSI-RS resources supported and configured at a network terminal is smaller than the number of cell-level CSI-RS resources used by a network side cell; the throughput rate of the part of the capacity-limited terminals can be improved by adopting the method.

As described above, the computer readable storage medium for performing dynamic configuration of signal resources according to this embodiment triggers acquisition of a second beam identifier of at least one second signal resource with the highest second reference signal received power by determining whether a difference between the first reference signal received power and the second reference signal received power is greater than a threshold value, so as to determine whether the terminal is within a coverage area of a first beam of an unallocated first signal resource according to the second beam identifier, and implement reallocation of resources based on a determination result. Therefore, on one hand, the throughput rate of the terminal with limited capacity can be improved; on the other hand, the first signal resource of the cell level can be dynamically allocated according to the terminal position, so that the accuracy of the downlink channel quality measurement of the terminal with limited capacity is improved; in another aspect, the influence on the load of the network side equipment is small, the difference value between the first reference signal received power and the second reference signal received power is firstly used for initial judgment, and after the initial judgment is successful, the first signal beam and the second signal beam are compared to determine the current position of the terminal.
Fig. 8 is a schematic structural view of a computer-readable storage medium of the present invention. Referring to fig. 8, a program product 800 for implementing the above-described method according to an embodiment of the present invention is described, which may employ a portable compact disc read only memory (CD-ROM) and include program code, and may be run on a terminal device, such as a personal computer. However, the program product of the present invention is not limited thereto, and in this document, a readable storage medium may be any tangible medium that can contain, or store a program for use by or in connection with an instruction execution system, apparatus, or device.

In summary, by determining whether the difference between the first reference signal received power and the second reference signal received power is greater than a threshold value, the method triggers acquisition of a second beam identifier of at least one second signal resource with the highest second reference signal received power, so as to determine whether the terminal is within a coverage area of a first beam of an unallocated first signal resource according to the second beam identifier, and reallocate resources is realized based on a determination result. Therefore, on one hand, the throughput rate of the terminal with limited capacity can be improved; on the other hand, the first signal resource of the cell level can be dynamically allocated according to the terminal position, so that the accuracy of the downlink channel quality measurement of the terminal with limited capacity is improved; in another aspect, the influence on the load of the network side equipment is small, the difference value between the first reference signal received power and the second reference signal received power is firstly used for initial judgment, and after the initial judgment is successful, the first signal beam and the second signal beam are compared to determine the current position of the terminal.
The foregoing is a further detailed description of the invention in connection with the preferred embodiments, and it is not intended that the invention be limited to the specific embodiments described.
