Description

Spectrum sharing apparatus, spectrum sharing method, and computer-readable storage medium

Technical Field

The present disclosure relates to a spectrum sharing apparatus, a spectrum sharing method, and a storage medium. More particularly, the present disclosure relates to techniques for dynamically sharing spectrum resources in a 4G/5G mobile communication network.

Background

Spectrum is a scarce resource in the field of communications, and with the development of 5G technologies and the continuous growth of 5G services, the demand for spectrum resources also rises sharply, and DSS (Dynamic spectrum sharing) is receiving wide attention as one of effective ways to solve the contradiction between spectrum supply and demand. The DSS technology can realize 4G/5G dynamic spectrum sharing, thereby meeting the respective traffic demands of 4G/5G users on limited spectrum resources and providing the best performance for 4G and 5G devices by utilizing the instantaneous dynamic spectrum sharing.

Disclosure of Invention

However, in the DSS technology, signal collision between LTE (Long Term Evolution) and NR (New Radio, New air interface, which may be referred to as a 5G network) needs to be avoided.

In the prior art, for example, in the scheme of sharing the Frequency band resource as shown in fig. 5, in a spectrum resource with a bandwidth of 50M, an LTE Frequency domain of an operator is configured in a range of 0 to 20M, and 2 OFDM (Orthogonal Frequency Division Multiplexing) symbols with numbers "0 and 1" are allocated to an LTE PDCCH (Physical Downlink Control Channel), and 1 OFDM symbol with number "2" is allocated to an NR PDCCH following the 2 OFDM symbols of the LTE PDCCH. As is clear from fig. 5, since the frequency domain range of the NR PDCCH is 20M or less, the number of symbols of the NR PDCCH is only 1 and the bandwidth is limited, and thus it is difficult to schedule a 50M PDSCH (Physical Downlink Shared Channel) with a large bandwidth.

As is clear from fig. 5, in the NR exclusive frequency domain of 20M to 50M, the symbol position of the NR PDSCH is advanced from the symbol positions of the NR PDCCH and the NR DMRS (Demodulation Reference Signal), and therefore, the Demodulation performance of the NR terminal is inevitably affected. Furthermore, in the spectrum resource allocation scheme of the prior art shown in fig. 5, signals such as NR SSB (Synchronization Signal and PBCH block) and LTE CRS RE are both present in the 0-20M frequency domain, so that collision is likely to occur, and solutions such as LTE puncturing, NR puncturing, or M subframe are required, which increases technical complexity, and deteriorates LTE and NR performance and capacity.

An object of the present disclosure is to provide a method capable of reducing LTE and NR 1:1 spectrum sharing apparatus, spectrum sharing method and storage medium for LTE and NR performance and capacity loss at deployment.

The following presents a simplified summary of the disclosure in order to provide a basic understanding of some aspects of the disclosure. However, it should be understood that this summary is not an exhaustive overview of the disclosure. It is not intended to identify key or critical elements of the disclosure or to delineate the scope of the disclosure. Its sole purpose is to present some concepts of the disclosure in a simplified form as a prelude to the more detailed description that is presented later.

According to an aspect of the present disclosure, a spectrum sharing apparatus is provided, configured to share spectrum resources in a scenario in which LTE is long term evolution and NR is a new air interface 1:1, where the spectrum sharing apparatus includes a processing circuit, and the processing circuit is configured to: initializing and configuring parameters, and configuring an NR control channel in an NR exclusive frequency domain; detecting the occupied bandwidth of an NR physical resource block (NR PBR); on/off control of a function switch for turning on/off a DSS, i.e., a dynamic spectrum sharing function, based on the detected occupied bandwidth of the NR PRB; and performing allocation of spectrum resources based on the on/off state of the function switch.

According to another aspect of the present disclosure, a spectrum sharing method is provided for sharing spectrum resources in a scenario in which LTE is long term evolution and NR is a new air interface 1:1 configuration, where the spectrum sharing method includes the following steps: initializing and configuring parameters, and configuring an NR control channel in an NR exclusive frequency domain; detecting the occupied bandwidth of an NR physical resource block (NR PBR); on/off control of a function switch for turning on/off a DSS, i.e., a dynamic spectrum sharing function, based on the detected occupied bandwidth of the NR PRB; and performing allocation of spectrum resources based on the on/off state of the function switch.

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

Detailed Description

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

Hereinafter, exemplary embodiments of spectrum sharing techniques according to embodiments of the present disclosure will be described with reference to the drawings.

Fig. 1 is a diagram schematically illustrating spectrum resource allocation in a spectrum sharing apparatus 2000 of an embodiment of the present disclosure.

As shown in fig. 1, in contrast to the prior art of fig. 5, the present disclosure:

1) and key signals such as NR SSB/RMSI/OSI and the like are transferred to a frequency domain with the size of 30M and 20M-50M exclusive to NR, so that the problem of resource conflict with RE occupied by LTE CRS is effectively solved, and DSS (LTE/NR) dynamic spectrum sharing is carried out in 50M. The LTE dynamic spectrum sharing range is 0-20M, the NR Static Spectrum Sharing (SSS) range is 30-50M, and the dark dotted horizontal line and the dark dotted arrow part in the graph do not exceed the black solid horizontal line; the NR Dynamic Spectrum Sharing (DSS) range is 0-20M, and light-colored dotted horizontal lines and light-colored dotted arrow parts are shown in the figure. Thereby reducing LTE and NR performance and capacity loss while scheme implementation complexity is reduced.

2) The NR PDCCH is migrated to an NR exclusive frequency domain from the 3 rd symbol (only 1 symbol) at the lower left, and is expanded to 2-3 OFDM symbols (dark solid arrows), and the frequency domain is also promoted to 30M from less than or equal to 20M, so that the capacity of the NR PDCCH is promoted, the number of NR users capable of being scheduled is increased, the CCE aggregation level is promoted, and the NR edge user experience is improved.

3) When the NR traffic becomes small, the NR traffic calls the NR spectrum resources in a manner of calling from 50M down to 20M (with a bandwidth of 30M). When the NR service does not exceed 30M, there is no need to use DSS, so the NR/LTE dynamic Spectrum sharing DSS function is turned off, and the NR/LTE does not generate signal overlapping or collision of the control channel and the traffic channel, and actually, a static Spectrum sharing sss (static Spectrum sharing) mode is used.

4) When the NR traffic becomes large, a dynamic spectrum sharing DSS function is activated, the NR PDSCH extends from the upper 30M to the lower 20M of LTE, and the NR PDSCH extending to the LTE 20M region avoids Resource collision with RE (Cell Reference Signal) occupied by LTE CRS through RE-level rate matching.

5) When the LTE traffic becomes larger, a CFI (Control Format Indicator) dynamic indication may be further adopted to promote the LTE PDCCH from 2 OFDM symbols to 3 OFDM symbols (light-colored solid arrow), so as to break through the limitation of 2 OFDM symbols in the conventional scheme (the 3 rd OFDM symbol is allocated to the NR PDCCH), and thus promote the PDCCH capacity of LTE (that is, increase the number of LTE users that can be scheduled).

Here, "50M" is merely an example of a bandwidth size shared by resources, and a guard bandwidth or the like is considered, and for example, the shared bandwidth size may be 30M, 35M, 40M, 45M, 55M, 60M, 80M,100M, or the like.

Fig. 2 is an exemplary configuration block diagram schematically illustrating a spectrum sharing apparatus 2000 of an embodiment of the present disclosure.

In some embodiments, as shown in fig. 2, the spectrum sharing device 2000 may include a processing circuit 2010. The processing circuitry 2010 of the spectrum sharing device 2000 provides various functions of the spectrum sharing device 2000. In some embodiments, the processing circuitry 2010 of the spectrum sharing device 2000 may be configured to perform a spectrum sharing method in the spectrum sharing device 2000.

Processing circuit 2010 may refer to various implementations of digital circuitry, analog circuitry, or mixed-signal (a combination of analog and digital) circuitry that performs functions in a computing system. The processing circuitry may include, for example, circuitry such as an Integrated Circuit (IC), an Application Specific Integrated Circuit (ASIC), portions or circuits of an individual processor core, an entire processor core, an individual processor, a programmable hardware device such as a Field Programmable Gate Array (FPGA), and/or a system including multiple processors.

In some embodiments, the processing circuitry 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, a DSS/SSS function execution unit 2050. Here, the initialization and parameter configuration unit 2020 is configured to perform step S1001 in fig. 3 and steps S2001 and S2002 in the flowchart in fig. 4, which will be described later, the NR PRB detection unit 2030 is configured to perform step S1002 in fig. 3 and step S2003 in the flowchart in fig. 4, which will be described later, the DSS function switch control unit 2040 is configured to perform step S1003 in the flowchart in fig. 3 and steps S2004 to S2005 and S2008 in fig. 4, which will be described later, and the DSS/SSS function execution unit 2050 is configured to perform step S1004 in the flowchart in fig. 3, and steps S2006 to S2007 and S2009 to S2010 in the flowchart in fig. 4, which will be described later.

In some embodiments, the spectrum sharing device 2000 may further include a memory (not shown). The memory of the spectrum sharing device 2000 may store information generated by the processing circuit 2010, as well as programs and data for operation of the spectrum sharing device 2000. The memory may be volatile memory and/or non-volatile memory. For example, memory may include, but is not limited to, Random Access Memory (RAM), Dynamic Random Access Memory (DRAM), Static Random Access Memory (SRAM), Read Only Memory (ROM), and flash memory.

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

It should be understood that the initialization and parameter configuration unit 2020, the NR PRB detection unit 2030 and the DSS/SSS function execution unit 2040 are merely logic modules divided according to specific functions implemented by them, and are not used to limit specific implementations. In actual implementation, the above units may be implemented as separate physical entities, or may also be implemented by a single entity (e.g., a processor (CPU or DSP, etc.), an integrated circuit, etc.).

Fig. 3 is an exemplary flowchart simply illustrating a spectrum sharing method performed in the spectrum sharing apparatus 2000 according to an embodiment of the present disclosure. First, in step S1001, in an initialization procedure, control channels such as NR SSB/RMSI (Remaining minimum System Information)/OSI (Other System Information) are allocated in 20M to 50M, that is, an exclusive frequency domain of NR. Furthermore, in the initialization process, the LTE PDCCH is configured in an LTE frequency domain of 0-20M, and 2-3 OFDM symbols are allocated.

Then, in step S1002, NR PRB resource occupancy is detected. In some embodiments, the NR PRB maximum occupied bandwidth is detected periodically every predetermined time, e.g. 1S, 10S, etc. In some embodiments, the NR PRB maximum occupied bandwidth may also be detected at a set time. In addition, in some embodiments, instead of detecting the maximum occupied bandwidth of NR PRBs, the average occupied bandwidth of NR PRBs may be detected.

In step S1003, on/off control is performed on a function switch for turning on/off the DSS function according to the detected NR PRB resource occupancy. The specific opening/closing control process is described in detail later.

Then, in step S1004, based on the state (on/off) of the function switch, spectrum resource allocation (DSS/SSS) is performed accordingly.

The spectrum sharing method of the present disclosure is described in detail below with reference to fig. 4. Fig. 4 is an exemplary flowchart illustrating a spectrum sharing method performed in the spectrum sharing apparatus 2000 according to an embodiment of the disclosure in more detail.

First, during the DSS boot phase, the initialization and parameter configuration unit 2020 performs initialization and parameter configuration. Specifically, in step S2001, initialization and parameter allocation section 2020 allocates a key signal such as NR SSB/RMSI/OSI, which is likely to collide with an LTE CRS signal, to an NR exclusive frequency domain having a bandwidth of 20M to 50M, that is, 30M. Therefore, the problem of resource conflict with RE occupied by LTE CRS is effectively solved, and schemes such as LTE punching, NR punching, M subframes and the like do not need to be adopted, so that the complexity of the technical scheme of 50M DSS is reduced.

Further, in step S2002, initialization and parameter allocation section 2020 allocates the LTE PDCCH to the LTE frequency domain of 0 to 20M and allocates an OFDM symbol to the LTE PDCCH. In some embodiments, when the traffic of LTE exceeds a preset threshold, the number of OFDM symbols of LTE PDCCH is increased from 2 to 3 (as shown by the light-colored arrow at the bottom left of fig. 1), so as to break the limitation that only 2 OFDM symbols are used in the conventional scheme (as shown in fig. 5, the 3 rd symbol is allocated to NR PDCCH in the prior art), which can improve the PDCCH capacity of LTE and increase the number of LTE users that can be scheduled.

Then, in step S2003, the NR PRB detecting unit 2030 detects the NR PRB occupied bandwidth, for example, at every predetermined time of 1 second. The physical resource module PRB is a physical resource allocation unit of an air interface, and is 12 continuous carrier resources in a frequency domain, and is 180KHz in the case of a carrier interval of 15 KHz. Note that, although 1 second intervals are exemplified as the predetermined time, the time interval for detecting NR PRB may be set appropriately according to specific needs, and may be, for example, 10 seconds. Further, the NR PRB resource occupancy detection may not be performed periodically every predetermined time but may be performed at a predetermined timing.

In some embodiments, in this step S2003, the NR PRB detecting unit 2030 detects the maximum occupied bandwidth of NR PRBs. In some embodiments, in this step S2003, the NR PRB detecting unit 2030 detects the average occupied bandwidth of NR PRBs. Specifically, which occupied bandwidth is detected can be set according to needs.

Next, in step S2004, the DSS function switch control unit 2040 performs on/off control of the function switch for turning on/off the 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), and when the NR PRB occupied bandwidth is equal to or less than 30M, that is, equal to or less than the NR exclusive bandwidth (in the case of no in step S2004), the NR PRB does not need to be extended to the LTE frequency domain in the frequency domain, so the process proceeds to step S2005, and the DSS function switch control unit 2040 turns off the DSS function switch (DSS _ switch off).

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).

Then, in step S2007, the DSS/SSS function executing unit 2050 performs SSS, that is, static spectrum sharing, configures NR PDSCH in the frequency domain exclusive to NR (20M to 50M), and calls NR spectrum resources in a manner of calling downward from 50M to 20M (bandwidth 30M). In this case, the LTE control channel and the traffic channel do not collide with each other, and thus, the LTE and NR performance and capacity loss can be effectively reduced.

Returning to the description of step S2004, when the occupied bandwidth of NR PRB is greater than 30M, that is, greater than the NR exclusive bandwidth (yes in step S2004), NR PRB needs to be extended to the LTE frequency domain for smooth NR traffic spreading, and the process proceeds to step S2008, where DSS function switch control section 2040 turns on DSS function switch (DSS _ switch ═ on)

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 increased, the number of users whose NR can be scheduled can be increased, and the CCE aggregation level can be improved, thereby improving the NR edge user experience.

In step S2010, the DSS/SSS function executing unit 2050 is configured to: the NR PDSCH extends from the upper 20M-50M NR exclusive frequency domain to the lower 0-20MLTE frequency domain, and the NR PDSCH configured to extend to the 0-20M region of LTE avoids collision with REs occupied by LTE CRS through RE-level rate matching.

According to the spectrum sharing apparatus 2000 of the exemplary embodiment of the disclosure, by shifting a key signal (which is likely to collide with an LTE CRS) such as NR SSB/RMSI/OSI to an NR exclusive region, the NR PDCCH is promoted from 1 OFDM symbol to 2 to 3 OFDM symbols, and the frequency domain is promoted from 20M or less to 30M, so that the PDCCH capacity of NR can be promoted, the number of users whose NR can be scheduled can be increased, the CCE aggregation level can be promoted, and the NR edge user experience can be improved.

In addition, according to the spectrum sharing apparatus 2000 of the exemplary embodiment of the present disclosure, an LTE/NR puncturing or M subframe scheme is not required, and by a method combining NR SSB/RMSI/OSI and other signal position migration, PDCCH capacity elevation, and static and dynamic spectrum resource sharing techniques, the LTE/NR collision avoidance problem is effectively solved, LTE and NR performance and capacity loss are reduced, meanwhile, the complexity of the technical scheme for implementing LTE and NR collision avoidance is reduced, DSS networking flexibility and resource utilization rate are improved, 4G/5G user experience is improved, DSS operation and maintenance and optimization cost are reduced, and it is helpful to rapidly promote 5G service rapid development and 5G SA user proliferation.

Furthermore, according to the spectrum sharing apparatus 2000 of the exemplary embodiment of the present disclosure, the number of OFDM symbols of the LTE PDCCH can be increased according to the size of the detected LTE PBR, so that the PDCCH capacity of LTE can be increased, the number of users that can be scheduled by LTE can be increased, spectrum resources can be flexibly applied, and the resource utilization rate of the system can be improved.
