Description

Technical Field

[0001] The present disclosure relates to a spectrum sharing apparatus, a spectrum sharing method, and a storage medium. More specifically, the present disclosure relates to a technology for dynamically sharing spectrum resources in a 4G / 5G mobile communication network. Background Art

[0002] Spectrum is a scarce resource in the communication field. With the development of 5G technology and the continuous growth of 5G services, the demand for spectrum resources has also increased sharply. As one of the effective ways to solve the contradiction between spectrum supply and demand, DSS (Dynamic Spectrum Sharing) has received wide attention. Through DSS technology, 4G / 5G dynamic spectrum sharing can be achieved, so as to meet the respective traffic demands of 4G / 5G users on limited spectrum resources, and provide the best performance for 4G and 5G devices by using the instantaneous dynamic sharing of spectrum. Summary of the Invention

[0003] However, in DSS technology, signal conflicts between LTE (Long Term Evolution) and NR (New Radio, which can be used to refer to the 5G network) need to be avoided.

[0004] In the prior art, for example, in the scheme of sharing frequency band resources as Figure 5 shown, in the spectrum resources with a bandwidth of 50M, the LTE frequency domain configuration of the operator is in the range of 0 - 20M, and the LTE PDCCH (Physical Downlink Control Channel) is allocated 2 OFDM (Orthogonal Frequency Division Multiplexing) symbols numbered "0, 1". Immediately following the 2 OFDM symbols of the LTE PDCCH, 1 OFDM symbol numbered "2" is allocated for the NR PDCCH. According to Figure 5 it can be known that the frequency domain range of the NR PDCCH is less than or equal to 20M. Therefore, since the number of symbols of the NR PDCCH is only 1 and the bandwidth is limited, it is difficult to schedule the PDSCH (Physical Downlink Shared Channel) with a large bandwidth of 50M.

[0005] In addition, according to Figure 5It can be seen that in the exclusive frequency domain of NR from 20M to 50M, the symbol position of NR PDSCH is ahead of the symbol positions of NR PDCCH and NR DMRS (Demodulation Reference Signal), so inevitably, it will affect the demodulation performance of NR terminals. Further, in Figure 5 In the spectrum resource allocation scheme of the prior art shown, signals such as NR SSB (Synchronization Signal and PBCH block) and LTE CRS RE both exist in the frequency domain from 0 to 20M, so conflicts are likely to occur, and solutions such as LTE punching, NR punching, or M sub-frames need to be adopted, which increases the technical complexity, and at the same time, the performance and capacity of LTE and NR are severely damaged.

[0006] An object of the present disclosure is to provide a spectrum sharing device, a spectrum sharing method, and a storage medium that can reduce the performance and capacity losses of LTE and NR in a 1:1 configuration of LTE and NR in 4G / 5G spectrum resource sharing.

[0007] A brief overview of the present disclosure is given below to provide a basic understanding of some aspects of the present disclosure. However, it should be understood that this overview is not an exhaustive overview of the present disclosure. It is not intended to identify the key or important parts of the present disclosure, nor is it intended to limit the scope of the present disclosure. Its purpose is only to present some concepts of the present disclosure in a simplified form as a prelude to the more detailed description given later.

[0008] According to one aspect of the present disclosure, there is provided a spectrum sharing device for sharing spectrum resources in a scenario where LTE (Long-Term Evolution) and NR (New Radio) are in a 1:1 configuration. The spectrum sharing device includes a processing circuit configured to: perform initialization and parameter configuration, configure the NR control channel in the exclusive frequency domain of NR; detect the occupied bandwidth of the NR physical resource block, i.e., NR PBR; based on the detected occupied bandwidth of the NR PRB, control the opening / closing of a function switch for enabling / disabling the DSS (Dynamic Spectrum Sharing) function; and based on the opening / closing state of the function switch, perform the allocation of spectrum resources.

[0009] According to another aspect of the present disclosure, a spectrum sharing method is provided for sharing spectrum resources in a scenario where LTE (Long-Term Evolution) and NR (New Radio) are configured in a 1:1 ratio. The spectrum sharing method includes the following steps: performing initialization and parameter configuration, configuring the NR control channel in the NR exclusive frequency domain; detecting the occupied bandwidth of the NR physical resource block, i.e., NR PBR; based on the detected occupied bandwidth of the NR PRB, controlling the opening / closing of a function switch for enabling / disabling the DSS (Dynamic Spectrum Sharing) function; and based on the opening / closing state of the function switch, performing the allocation of spectrum resources.

[0010] According to another aspect of the present disclosure, a computer-readable storage medium is provided, including executable instructions that, when executed by a computer, cause the computer to execute the above spectrum sharing method.

[0011] According to the present disclosure, in the 4G / 5G spectrum resource sharing, it is possible to reduce the performance and capacity losses of LTE and NR in the 1:1 configuration of LTE and NR. The method of this patent is applicable not only to 50M DSS, but also to DSS greater than 50M, such as 55M, 60M, 80M, 100M, etc., and also to DSS less than 50M, such as 30M, 35M, 40M, 45M, etc. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] Hereinafter, preferred embodiments of the present disclosure will be described in detail with reference to the accompanying drawings. It should be noted that in this specification and the accompanying drawings, structural elements having substantially the same function and structure are denoted by the same reference numerals, and repeated descriptions of these structural elements are omitted.

[0020] Hereinafter, an exemplary embodiment of the spectrum sharing technology according to an embodiment of the present disclosure will be described with reference to the accompanying drawings.

[0021] Figure 1 FIG. 2000 schematically shows the spectrum resource allocation in a spectrum sharing apparatus 2000 according to an embodiment of the present disclosure.

[0022] As Figure 1 shown, compared with Figure 5 the prior art, the present disclosure:

[0023] 1) Migrate key signals such as NR SSB / RMSI / OSI to a 30M-sized frequency domain of 20M to 50M exclusive to NR, thereby effectively solving the problem of conflict with the RE resources occupied by LTE CRS, and performing DSS (LTE / NR) dynamic spectrum sharing within 50M. Among them, the LTE dynamic spectrum sharing range is 0-20M, the NR static spectrum sharing (SSS) range is 30-50M, as shown by the dark dashed horizontal line and dark dashed arrow in the figure, not exceeding the black solid horizontal line; the NR dynamic spectrum sharing (DSS) range is 0-20M, as shown by the light dashed horizontal line and light dashed arrow in the figure. Thereby reducing the performance and capacity loss of LTE and NR, while reducing the implementation complexity of the solution.

[0024] 2) Migrate the NR PDCCH from the 3rd symbol (only 1 symbol) from the lower left to the NR exclusive frequency domain and expand it to 2-3 OFDM symbols (dark solid arrow), and the frequency domain is also increased from less than or equal to 20M to 30M, thereby improving the PDCCH capacity of NR, increasing the number of NR users that can be scheduled, and improving the CCE aggregation level, improving the experience of NR edge users.

[0025] 3) When the NR traffic volume decreases, the NR service calls the NR spectrum resources in a way of downward call from 50M to 20M (bandwidth is 30M). And when the NR service does not exceed 30M, it is not necessary to adopt DSS, so the NR / LTE dynamic spectrum sharing DSS function is turned off, and there will be no signal overlap or conflict in the control channel and service channel between NR / LTE. Actually, the static spectrum sharing SSS (Static Spectrum Sharing) method is adopted.

[0026] 4) When the NR traffic volume increases, the dynamic spectrum sharing DSS function is started. The NR PDSCH extends from the upper 30M to the lower 20M of LTE. The NR PDSCH extended to the 20M area of LTE avoids conflicting with the RE resources occupied by the LTE CRS (Cell Reference Signal) through RE (Resource Element) - level rate matching.

[0027] 5) When the LTE traffic volume increases, CFI (Control Format Indicator) dynamic indication can also be adopted to increase the LTE PDCCH from 2 OFDM symbols to 3 OFDM symbols (light solid arrow), thus breaking through the limitation of 2 OFDM symbols in the traditional scheme (the 3rd OFDM symbol is allocated to the NR PDCCH), and thus improving the PDCCH capacity of LTE (that is, increasing the number of LTE users that can be scheduled).

[0028] In addition, here, "50M" is only an example of the bandwidth size for resource sharing. Considering the protection bandwidth, etc., for example, the shared bandwidth size can also be 30M, 35M, 40M, 45M, 55M, 60M, 80M, 100M, etc.

[0029] Figure 2 FIG. is a schematic configuration block diagram of a spectrum sharing apparatus 2000 showing an embodiment of the present disclosure.

[0030] In some embodiments, as Figure 2 shown, the spectrum sharing apparatus 2000 may include a processing circuit 2010. The processing circuit 2010 of the spectrum sharing apparatus 2000 provides various functions of the spectrum sharing apparatus 2000. In some embodiments, the processing circuit 2010 of the spectrum sharing apparatus 2000 may be configured to execute the spectrum sharing method in the spectrum sharing apparatus 2000.

[0031] Processing circuit 2010 may refer to various implementations of digital circuit systems, analog circuit systems, or mixed-signal (a combination of analog and digital) circuit systems that perform functions in a computing system. The processing circuit may include, for example, circuits such as integrated circuits (ICs), application-specific integrated circuits (ASICs), parts or circuits of individual processor cores, entire processor cores, individual processors, programmable hardware devices such as field-programmable gate arrays (FPGAs), and / or systems including multiple processors.

[0032] In some embodiments, the processing circuit 2010 may include an initialization and parameter configuration unit 2020, an NR PRB (physical resource block) detection unit 2030, a DSS function switch control unit 2040, and a DSS / SSS function execution unit 2050.

[0033] In some embodiments, the spectrum sharing device 2000 may further include a memory (not shown).

[0034] In addition, the spectrum sharing device 2000 may be implemented at the chip level, or may also be implemented at the device level by including other external components.

[0035] It should be understood that the above initialization and parameter configuration unit 2020, NR PRB detection unit 2030, and DSS / SSS function execution unit 2040 are only logical modules divided according to their specific implemented functions, rather than being used to limit specific implementation manners. In actual implementation, the above-mentioned respective units can be implemented as independent physical entities, or can also be implemented by a single entity (for example, a processor (CPU or DSP, etc.), an integrated circuit, etc.).

[0036] Figure 3 is a schematic flowchart simply showing the spectrum sharing method executed in the spectrum sharing device 2000 according to an embodiment of the present disclosure. Hereinafter, in combination with Figure 3 briefly describe the spectrum resource sharing of the present disclosure. First, in step S1001, in the initialization process, control channels such as NR SSB / RMSI (Remaining minimum system information) / OSI (Other System Information) are configured in the 20M - 50M, that is, the exclusive frequency domain of NR. Further, in the initialization process, LTE PDCCH is configured in the LTE frequency domain of 0 - 20M and 2 to 3 OFDM symbols are allocated.

[0037] Then, in step S1002, detect the occupancy situation of NR PRB resources. In some embodiments, at regular intervals, such as every 1S, 10S, etc., detect the maximum occupied bandwidth of NR PRB. In some embodiments, the maximum occupied bandwidth of NR PRB can also be detected at a set time. Additionally, in some embodiments, instead of detecting the maximum occupied bandwidth of NR PRB, the average occupied bandwidth of NR PRB can be detected.

[0038] In step S1003, according to the detected occupancy situation of NR PRB resources, control the opening / closing of the function switch for turning on / off the DSS function. The specific opening / closing control process will be described in detail later.

[0039] Then, in step S1004, based on the state (open / closed) of the function switch, correspondingly perform spectrum resource allocation (DSS / SSS).

[0040] Hereinafter, in combination with Figure 4 , detail the spectrum sharing method of the present disclosure. Figure 4 is a schematic flowchart more detailedly showing the spectrum sharing method executed in the spectrum sharing device 2000 according to an embodiment of the present disclosure.

[0041] First, during the DSS startup phase, the initialization and parameter configuration unit 2020 performs initialization and parameter configuration. Specifically, in step S2001, the initialization and parameter configuration unit 2020 configures key signals such as NR SSB / RMSI / OSI that are prone to conflict with LTE CRS signals in the exclusive NR frequency domain of 20M - 50M, that is, a 30M bandwidth. Thereby, the problem of conflict with the RE resources occupied by LTE CRS is effectively solved, and solutions such as LTE puncturing, NR puncturing, and M sub - frames do not need to be adopted, thus reducing the complexity of the 50M DSS technical solution.

[0042] Furthermore, in step S2002, the initialization and parameter configuration unit 2020 configures LTE PDCCH in the LTE frequency domain of 0 - 20M and allocates OFDM symbols for it. In some embodiments, when the traffic volume of LTE exceeds a preset threshold, the number of OFDM symbols of LTE PDCCH is increased from 2 to 3 (as Figure 1 shown by the light - colored arrow at the lower left), thereby breaking the limitation of only 2 OFDM symbols in the traditional solution (as Figure 5 shown, in the prior art, the third symbol is allocated to NR PDCCH), which can improve the PDCCH capacity of LTE and increase the number of LTE users that can be scheduled.

[0043] Then, in step S2003, the NR PRB detection unit 2030 detects the occupied bandwidth of NR PRB, for example, every predetermined time of 1 second. Among them, the physical resource block PRB is the physical resource allocation unit of the air interface, which is 12 consecutive carrier resources in the frequency domain and is 180KHz in the case of a 15KHz carrier spacing. In addition, here, an interval of 1 second is illustrated as the predetermined time, but the time interval for detecting NR PRB can be set appropriately according to specific needs. For example, it can also be 10 seconds, etc. Furthermore, it is not necessary to perform the NR PRB resource occupancy detection regularly every predetermined time, but it can be performed at a preset timing.

[0044] In some embodiments, in this step S2003, the NR PRB detection unit 2030 detects the maximum occupied bandwidth of NR PRB. In some embodiments, in this step S2003, the NR PRB detection unit 2030 detects the average occupied bandwidth of NR PRB. Which occupied bandwidth to specifically detect can be set according to needs.

[0045] Next, in step S2004, the DSS function switch control unit 2040 controls the opening / closing of the function switch for turning on / off DSS based on the NR PRB bandwidth occupancy detected by the NR PRB detection unit 2030. Specifically, the DSS function switch control unit 2040 compares the NR PRB occupied bandwidth with the NR exclusive bandwidth (30M). When the NR PRB occupied bandwidth is less than or equal to 30M, that is, less than or equal to the NR exclusive bandwidth (in the case of "No" in step S2004), in the frequency domain, the NR PRB does not need to extend to the LTE frequency domain. Therefore, the process proceeds to step S2005, and the DSS function switch control unit 2040 turns off the DSS function switch (DSS_switch = off).

[0046] Next, in step S2006, the DSS / SSS function execution unit 2050 configures two OFDM symbols numbered "0, 1" for the NR PDCCH in the NR exclusive frequency domain (20M - 50M).

[0047] Then, in step S2007, the DSS / SSS function execution unit 2050 performs SSS, i.e., static spectrum sharing, configures the NR PDSCH in the NR exclusive frequency domain (20M - 50M), and calls the NR spectrum resources in a downward call manner from 50M to 20M (bandwidth 30M). At this time, there will be no conflict between the LTE control channel and the traffic channel, thus effectively reducing the performance and capacity loss of LTE and NR.

[0048] Returning to the description of step S2004, when the NR PRB occupied bandwidth is greater than 30M, that is, greater than the NR exclusive bandwidth (in the case of "Yes" in step S2004), in order to smoothly carry out the NR service, the NR PRB needs to extend to the LTE frequency domain. At this time, the process proceeds to step S2008, and the DSS function switch control unit 2040 turns on the DSS function switch (DSS_switch = on).

[0049] Then, in step S2009, the DSS / SSS function execution unit 2050 configures three OFDM symbols numbered 0 - 2 for the NR PDCCH in the NR exclusive frequency domain (20M - 50M). By increasing the number of symbols of the NR PDCCH, the capacity of the NR PDCCH can be improved, the number of schedulable NR users can be increased, the CCE aggregation level can be enhanced, thereby improving the experience of NR edge users.

[0050] In step S2010, the DSS / SSS function execution unit 2050 is configured such that the NR PDSCH extends from the upper 20M - 50M NR exclusive frequency domain to the lower 0 - 20M LTE frequency domain, and the NR PDSCH configured to extend to the 0 - 20M area of LTE avoids conflicts with the REs occupied by the LTE CRS through RE-level rate matching.

[0051] For the spectrum sharing device 2000 according to an exemplary embodiment of the present disclosure, by migrating key signals such as NR SSB / RMSI / OSI (which are prone to conflict with the LTE CRS) to the NR exclusive area, the NR PDCCH is increased from 1 OFDM symbol to 2 - 3 OFDM symbols, and the frequency domain is also increased from less than or equal to 20M to 30M. As a result, the PDCCH capacity of NR can be improved, the number of schedulable users in NR can be increased, the CCE aggregation level can be enhanced, and the experience of NR edge users can be improved.

[0052] In addition, for the spectrum sharing device 2000 according to an exemplary embodiment of the present disclosure, there is no need to adopt the LTE / NR puncturing or M subframe scheme. By combining methods such as signal position migration of NR SSB / RMSI / OSI, PDCCH capacity improvement, and static and dynamic spectrum resource sharing technologies, the problem of LTE / NR conflict avoidance is effectively solved, the performance and capacity losses of LTE and NR are reduced, and at the same time, the complexity of the technical solution for implementing LTE and NR conflict avoidance is reduced, the flexibility of DSS networking and resource utilization rate are improved, the user experience of 4G / 5G is enhanced, and the DSS operation and maintenance and optimization costs are reduced, which helps to rapidly promote the rapid development of 5G services and the surge of 5G SA users.

[0053] Furthermore, for the spectrum sharing device 2000 according to an exemplary embodiment of the present disclosure, the number of OFDM symbols of the LTE PDCCH can also be increased according to the detected size of the LTE PBR. Therefore, the PDCCH capacity of LTE can be improved, the number of users that LTE can schedule can be increased, and the spectrum resources can be flexibly applied, thereby improving the resource utilization rate of the system.
