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, a CSI-RS (Channel state information-Reference Signal) used for downlink Channel measurement is divided into a UE (User Equipment) level and a cell level.
The CSI-RS of the UE level allocates a proprietary CSI-RS resource to each accessed terminal, and has the advantages that the wave beam of the CSI-RS is directed to user equipment (terminal), and the gain of wave beam forming is high; the disadvantage is that the resource overhead is large.
The CSI-RS of a cell level is a CSI-RS resource shared by all terminals in a cell, and the CSI-RS beam pointing direction is fixed and is not pointed to a specific terminal. Its advantages are low cost; the disadvantage is that the wave beam of the CSI-RS is wide wave beam, and the forming gain is lower than the CSI-RS resource of the UE level.
At present, the CSI-RS resources at the cell level are generally statically allocated to the terminal, and if the terminal capability is limited and the number of the CSI-RS resources at the cell level supporting configuration is less than the number of the resources actually used by the cell at the network side, the base station can only configure the CSI-RS resources for the terminal according to the terminal capability, that is, configure the CSI-RS resources at a partial cell level for the terminal; the following problems are: if the terminal moves to the condition that the terminal is not covered by the wave beam corresponding to the CSI-RS resource configured to the terminal, the terminal measures the wave beam corresponding to the CSI-RS resource allocated to the terminal to report the channel quality, so that the difference between the measured channel quality and the actual measured channel quality is larger. 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 a coverage area of a CSI-RS beam 4, at this time, the terminal 100 still measures beams corresponding to the CSI-RS beam 1 and the CSI-RS beam 2 allocated to it to report channel quality, which will cause a large difference between the measured channel quality and the actual channel quality.
Therefore, a technical problem to be solved by those skilled in the art is urgently needed to realize how to implement signal resource allocation to ensure that a terminal is located within a coverage area of allocated signal resources, and avoid a situation that a difference between a channel quality measured by the terminal and an actual channel quality is large.

Detailed Description
Example embodiments will now be described more fully with reference to the accompanying drawings. Example embodiments may, however, 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 example embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and thus their repetitive description will be omitted.
Referring to fig. 2, fig. 2 is a flowchart of an embodiment of a method for dynamically configuring signal resources according to the present invention. The embodiment of the invention provides a method for dynamically configuring signal resources, which comprises the following steps:
step S210: a first signal resource is allocated to a terminal.
Specifically, the first signal resource is a channel state information reference signal (CSI-RS) resource.
Step S220: and receiving a first reference signal receiving power of a first signal resource and a second reference signal receiving power of a 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 (SSB), and is composed of three parts, namely Primary Synchronization Signals (PSS), Secondary Synchronization Signals (SSS), and Physical Broadcast Channels (PBCH).
RSRP (Reference Signal Receiving Power) is one of the key parameters that can represent the wireless Signal strength in LTE networks and the physical layer measurement requirements, and is the average of the received Signal Power over all REs (resource elements) that carry Reference signals within a certain symbol.
Step S230: and judging whether the difference value of the first reference signal receiving power and the second reference signal receiving power is larger than a threshold value.
Specifically, the threshold value may be set as needed, 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, execute step S240: and acquiring a second beam identifier of at least one second signal resource with the highest second reference signal receiving power reported by the terminal.
Specifically, in some embodiments, the number of the second beam identifications obtained in step S240 is two. The present application is not so limited.
Step S250: and judging whether the terminal is in the coverage range of the first beam of the unallocated first signal resource or not according to the second beam identifier.
Specifically, the network side may determine the coverage of each beam (SSB/CSI-RS/service beam, etc.) and the corresponding relationship 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 a coverage range of a second beam associated with the second beam identifier; acquiring the coverage range of each first wave beam; and judging whether the terminal is in the coverage range of the first beam of the unallocated first signal resource or not according to the coverage relationship between the coverage range of the second beam associated with the second beam identifier and the coverage range of the first beam. Thus, the judgment of the coverage relation of the coverage can be realized.
If yes in step S250, execute step S260: and allocating a first signal resource covering the current position of the terminal to the terminal.
Specifically, since the maximum number of supporters of the terminal is limited, when the step S260 is performed, a step of de-allocating the first signal resource allocated to the terminal from the terminal may be further performed, thereby satisfying the maximum number of supporters of the terminal.
The method and the device trigger 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, judge whether the terminal is in the coverage range of the first beam of the first signal resource which is not allocated according to the second beam identifier, and realize the reallocation of the resources based on the judgment result. Therefore, on one hand, the throughput rate of the terminal with limited capability can be improved; on the other hand, the first signal resource of the cell level can be dynamically allocated according to the position of the terminal, so that the accuracy of the downlink channel quality measurement of the terminal with limited capability is improved; on the other hand, the influence on the load of the network side equipment is small, the difference value of the first reference signal receiving power and the second reference signal receiving power is used for initial judgment, and the first signal beam and the second signal beam are compared after the initial judgment is successful, so that the current position of the terminal is determined.
Referring now to fig. 3, fig. 3 is a flow chart of another embodiment of a method for dynamically configuring signal resources in accordance with 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 in which the terminal is located;
if the determination in step S320 is no, step S330 is executed: and allocating all first signal resources of the cell where the terminal is located to the terminal. Steps S340 to S390 are not performed.
If the determination in step S320 is yes, step S340 is executed: and allocating a first signal resource to the terminal according to the maximum support number.
Step S350: and receiving a first reference signal receiving power of a first signal resource and a second reference signal receiving power of a second signal resource reported by the terminal.
Step S360: and judging whether the difference value of the first reference signal receiving power and the second reference signal receiving power is larger than a threshold value.
If yes in step S360, go to step S370: and acquiring a second beam identifier of at least one second signal resource with the highest second reference signal receiving power reported by the terminal.
Step S380: and judging whether the terminal is in the coverage range of the first beam of the unallocated first signal resource or not according to the second beam identifier.
If yes in step S380, go to step S390: 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 diagram illustrating an embodiment of coverage of a terminal by a first signal beam and a second signal beam according to the present invention. In fig. 4, there are 4 CSI-RS resources (first signal resources) at the cell level, but the terminal 400 capability only supports the configuration of 2 CSI-RS resources, and thus the base station allocates CSI-RS resources 1 and 2 (first signal beam 1 and first signal beam 2) at the cell center position to the terminal. When the terminal 400 moves to the position in the figure, the base station detects that the difference value between the RSRP of the SSB (second signal resource) and the RSRP of the CSI-RS (first signal resource) reported by the terminal exceeds the threshold value. And then the base station determines that the terminal is currently under the beam coverage corresponding to the CSI-RS resource 4 which is not allocated to the terminal according to the condition that the terminal reports the best SSBRI (second beam identifier) of RSRP as 6 (second signal beam 6) and the best SSBRI (second beam identifier) of RSRP as 7 (second signal beam 7). The base station reallocates the CSI-RS resource to the terminal, and the new resource contains the CSI-RS resource 4, so that the terminal is always under the beam coverage corresponding to the allocated CSI-RS resource.
In the present application, the network side may determine the coverage of each beam (SSB/CSI-RS/service beam, etc.) and the corresponding relationship 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 2 SSB beam IDs (ssbris) 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 can set the terminal to report one or two CRI/SSBRIs in a groupbasedbeamrreporting field in the CSI-ReportConfig IE in the 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 larger 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 is currently under through the 2 best SSB beam IDs reported by the terminal. And if the cell-level CSI-RS resource covering the current position of the terminal is not allocated to the terminal, the network side reallocates the CSI-RS resource to the terminal and allocates the CSI-RS resource covering the position of the current terminal to the terminal. Therefore, the CSI-RS resources at the cell level can be dynamically allocated according to the position of the terminal, the terminal is ensured to be always under the coverage of the wave beam corresponding to the allocated CSI-RS resources, and the accuracy of channel measurement is ensured.
In 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 by a network terminal is less than the number of cell-level CSI-RS resources used by a cell of the network side; by adopting the method, the throughput rate of the part of terminals with limited capability can be improved.

Embodiments of the present invention further provide a computer-readable storage medium for storing a program, and the steps of the method for dynamically configuring signal resources when the program is executed are implemented. In some possible embodiments, the various aspects of the invention may also be implemented in the form of a program product comprising program code means for causing a terminal device to carry out the steps according to the various exemplary embodiments of the invention described in the method section of dynamically configuring signal resources mentioned above in this description, when the program product is run on the terminal device.
As shown above, the computer-readable storage medium for performing dynamic configuration of signal resources of 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, determines whether the terminal is in a coverage of a first beam of the first signal resource that is not allocated according to the second beam identifier, and implements reallocation of resources based on a determination result. Therefore, on one hand, the throughput rate of the terminal with limited capability can be improved; on the other hand, the first signal resource of the cell level can be dynamically allocated according to the position of the terminal, so that the accuracy of the downlink channel quality measurement of the terminal with limited capability is improved; on the other hand, the influence on the load of the network side equipment is small, the difference value of the first reference signal receiving power and the second reference signal receiving power is used for initial judgment, and the first signal beam and the second signal beam are compared after the initial judgment is successful, so that the current position of the terminal is determined.
Fig. 8 is a schematic structural diagram of a computer-readable storage medium of the present invention. Referring to fig. 8, a program product 800 for implementing the above 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 in this regard and, in the present 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.
The program product may employ any combination of one or more readable media. The readable medium may be a readable signal medium or a readable storage medium. A readable storage medium may be, for example, but not limited to, an electronic, magnetic, optical, electromagnetic, infrared, or semiconductor system, apparatus, or device, or any combination of the foregoing. More specific examples (a non-exhaustive list) of the readable storage medium include: an electrical connection having one or more wires, a portable disk, a hard disk, a Random Access Memory (RAM), a read-only memory (ROM), an erasable programmable read-only memory (EPROM or flash memory), an optical fiber, a portable compact disc read-only memory (CD-ROM), an optical storage device, a magnetic storage device, or any suitable combination of the foregoing.
A computer readable storage medium may include a propagated data signal with readable program code embodied therein, for example, in baseband or as part of a carrier wave. Such a propagated data signal may take many forms, including, but not limited to, electro-magnetic, optical, or any suitable combination thereof. A readable storage medium may also be any readable medium that is not a readable storage medium and that can communicate, propagate, or transport a program for use by or in connection with an instruction execution system, apparatus, or device. Program code embodied on a readable storage medium may be transmitted using any appropriate medium, including but not limited to wireless, wireline, optical fiber cable, RF, etc., or any suitable combination of the foregoing.
Program code for carrying out operations for aspects of the present invention may be written in any combination of one or more programming languages, including an object oriented programming language such as Java, C + + or the like and conventional procedural programming languages, such as the "C" programming language or similar programming languages. The program code may execute entirely on the user's computing device, partly on the user's device, as a stand-alone software package, partly on the user's computing device and partly on a remote computing device, or entirely on the remote computing device or server. In the case of a remote computing device, the remote computing device may be connected to the user computing device through any kind of network, including a Local Area Network (LAN) or a Wide Area Network (WAN), or may be connected to an external computing device (e.g., through the internet using an internet service provider).
In summary, the present application 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 in a coverage area of a first beam of the first signal resource that is not allocated 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 capability can be improved; on the other hand, the first signal resource of the cell level can be dynamically allocated according to the position of the terminal, so that the accuracy of the downlink channel quality measurement of the terminal with limited capability is improved; on the other hand, the influence on the load of the network side equipment is small, the difference value of the first reference signal receiving power and the second reference signal receiving power is used for initial judgment, and the first signal beam and the second signal beam are compared after the initial judgment is successful, so that the current position of the terminal is determined.
The foregoing is a more detailed description of the invention in connection with specific preferred embodiments and it is not intended that the invention be limited to these specific details. For those skilled in the art to which the invention pertains, several simple deductions or substitutions can be made without departing from the spirit of the invention, and all shall be considered as belonging to the protection scope of the invention.
