Detailed Description
For the purpose of making the objects, technical solutions and advantages of the present application more apparent, the technical solutions of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application, and it is apparent that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
In the course of the inventive process, the applicant considered the following aspects:
Currently, an operator has 160MHz spectrum resources in a 2.6GHz frequency band, and as the deployment of an operator mobile network evolves to 5G, the spectrum resources mainly have two use scenes in different stages: the first scenario is the mainstream usage at the present stage, namely LTE uses 60MHz bandwidth and 5G NR uses 100MHz bandwidth.
The second scenario is that after the LTE occupied spectrum is reshuffled to NR, it becomes 1 100MHz bandwidth NR cell and 1 60MHz bandwidth NR cell.
The two spectrum resources are used in a non-sharing mode, namely, a 100MHz cell and a 60MHz cell are independent in resources, so that a user in the 60MHz cell cannot obtain maximum bandwidth (100 MHz) service specified by a protocol, and the user experience effect is affected.
Thus, for these two scenarios, the industry has proposed a dynamic spectrum sharing method: in LTE/NR dynamic spectrum sharing in the first scenario, NR takes out a 40MHz Bandwidth as a shared spectrum, so that LTE can configure the largest 5CC, and the sharing manner is mainly carrier-level sharing between LTE and NR, and is implemented through BWP (Bandwidth Part Bandwidth) reconfiguration of NR, and carrier-level muting/activation of LTE.
This approach has the disadvantage that the time handling of the inter-LTE and NR resource coordination and the LTE muting activation is long, typically taking several seconds.
In the dynamic spectrum sharing between NR in the second scenario, two NR cells are configured as 100MHz bandwidth, and there is 40MHz shared bandwidth, so as to realize the dynamic spectrum sharing of two NR carriers, the two cell schedulers perform cooperative processing, schedule messages synchronously, and uniformly allocate spectrum resources.
Specifically, the process of dynamic spectrum sharing by the existing communication base station processing system is inter-cell shared spectrum resource negotiation performed by a high-layer signaling mode, including:
The communication base station of each cell comprises an NR100M transceiver module, an NR100M scheduling module and a high-level communication protocol processing module.
The NR100M receiving and transmitting module is used for transmitting data to the air interface spectrum according to the scheduling air interface spectrum resource result of the NR100M scheduling module.
The NR100M scheduling module is used for selecting available air interface spectrum resources, designating an air interface spectrum used for data transmission and feeding back the used shared spectrum condition to the high-level communication protocol processing module.
The high-level communication protocol processing module sends the shared spectrum use condition of the cell to other cells through the high-level communication signaling message, receives the shared spectrum use condition message sent by the high-level communication protocol processing module of other cells, and forwards the shared spectrum use condition of other cells to the NR100M scheduling module of the cell.
The inter-cell shared spectrum resource negotiation refers to NR100M scheduling modules of communication base stations of different cells, for example, cell 1 and cell 2, respectively receiving shared spectrum usage conditions of the other side, and negotiating and confirming each newly added use of the idle shared spectrum; or releasing the used shared spectrum into idle shared spectrum for the other party to use.
It can be seen that the above-mentioned inter-cell shared spectrum resource negotiation requires interaction of high-layer communication signaling messages between cells in a high-layer signaling manner, and has a long processing period, and the entire negotiation process generally requires seconds, which is low in efficiency and is unfavorable for popularization of dynamic spectrum sharing technology.
Based on the above considerations, the applicant has proposed embodiments of the present application.
The spectrum sharing method, the device, the electronic equipment and the storage medium provided by the invention are described in detail below with reference to the embodiments.
Fig. 1 is a schematic flow chart of a spectrum sharing method according to an embodiment of the present application. Referring to fig. 1, an embodiment of the present application provides a spectrum sharing method, which may include:
step S100, monitoring the resource occupation condition of a target frequency spectrum, wherein the target frequency spectrum is the frequency spectrum shared by at least two cells;
It should be noted that, the execution body of the spectrum sharing method provided in the embodiment of the present application may be a computer device, for example, a mobile phone, a tablet computer, a notebook computer, a palm computer, a vehicle-mounted electronic device, a wearable device, an ultra-mobile personal computer (UMPC), a netbook, a Personal Digital Assistant (PDA), or the like.
In this embodiment, the target spectrum is a spectrum shared by at least two cells in the air interface resource, that is, a shared spectrum. The specific number of shared cells is not limited in this embodiment.
The air interface resource refers to a high-frequency resource used for transmission between the mobile phone and the base station. The air resource in this embodiment may be 160MHz, for example.
The air resources in this embodiment may include shared spectrum and exclusive spectrum.
The shared spectrum may be a spectrum that may be shared for use by multiple cells; exclusive spectrum is spectrum that can only be used by one cell alone, while other cells cannot.
In some embodiments, if 160MHz in the air interface resource is only used by two cells, the first 60MHz may be used exclusively by the first cell, and the second 60MHz may be used exclusively by the second cell. The middle 40MHz is used as a shared spectrum, and can be dynamically adjusted to be used by a first cell or a second cell, so that the maximum usable bandwidth of the first cell and the second cell is 100MHz.
The resource occupation condition may include occupied and idle, and occupied may be occupied by one of the cells, or may be occupied by a plurality of cells at the same time. Idle means that the shared spectrum is not currently being used by a cell.
It should be noted that, when the resource occupation condition is occupied, the resource occupation condition may include occupation of the own cell, occupation of other cells, occupation of multiple cells (i.e. collision exists), and the like. Wherein, the multi-cell occupation, i.e. the simultaneous use of the shared spectrum by multiple cells, will cause the shared spectrum to collide.
It should be noted that, each cell may be provided with a communication base station, and each communication base station may include a shared spectrum monitoring module, an NR100M scheduling module, and an NR100M transceiver module. That is, a shared spectrum monitoring module is newly provided in a conventional communication base station, and a high-level communication protocol processing module is not required.
The shared spectrum monitoring module is used for monitoring the resource occupation condition of the shared spectrum in real time; the NR100M scheduling module is used for scheduling resources; the NR100M transceiver module is used for data transceiving.
Step S200, scheduling the resources of the target frequency spectrum for the request to be processed according to the resource occupation condition.
In this embodiment, the request to be processed may be a request to be processed, for example, a data transmission request, a data reception request, or the like.
The pending request may be a request sent by each cell when data processing is required.
The air interface resource scheduling may include allocating spectrum bandwidth for the request.
It can be appreciated that when a cell initiates a pending request, such as a data transmission request, the NR100M scheduling module may perform resource allocation and scheduling of the air interface spectrum, and preferentially use the resources of the exclusive spectrum corresponding to the cell.
When the resources of the exclusive spectrum of the cell are insufficient, the idle shared spectrum is scheduled to be used according to the resource occupation condition of the shared spectrum fed back by the shared spectrum monitoring module, and the resources of the shared spectrum close to one side of the cell are scheduled to be used.
Since the resource occupation condition includes idle, when the resource occupation condition is determined to be idle, all resources of the target spectrum, i.e. the shared spectrum, can be used for executing the pending request, thereby fully utilizing the air interface resources.
According to the spectrum sharing method provided by the embodiment of the application, the shared spectrum is monitored, so that the resource scheduling of the shared spectrum can be performed on the request to be processed in real time according to the resource occupation condition of the shared spectrum. The scheduling information does not need to be interacted between cells in a high-layer signaling mode, and the processing period of spectrum sharing can be shortened.
According to the embodiment, the resource occupation condition of the shared spectrum is monitored in real time in a local monitoring mode, the air interface resource scheduling is performed in real time, the resource scheduling efficiency of the shared spectrum is improved, and the real-time dynamic spectrum sharing is realized.
Fig. 2 is a second flowchart of a spectrum sharing method according to an embodiment of the present application. Referring to fig. 2, in one embodiment, monitoring the resource occupancy of a target spectrum includes:
step S101, scanning the receiving power of a target frequency spectrum;
in this embodiment, the received power of the target spectrum may be obtained by performing received power scanning on the shared spectrum that is the target spectrum, where the scanning accuracy of the received power may reach PRB (physical resource block).
Step S102, determining the resource occupation condition of the target frequency spectrum according to the received power.
After the receiving power of the target frequency spectrum is obtained, the receiving power can be compared with a preset power threshold value, and the resource occupation condition of the target frequency spectrum is determined according to the comparison result.
The preset power threshold may be, but not limited to, a power value corresponding to the background noise. Background noise is the background noise.
Further, determining the resource occupation condition of the target spectrum according to the received power includes:
And step A, determining that the resource occupation condition of the target frequency spectrum is idle if the received power is smaller than or equal to the preset power threshold value.
When a request to be processed is received, if the received power of the target frequency spectrum is determined to be smaller than or equal to the preset power threshold after the received power of the target frequency spectrum is compared with the preset power threshold, the received power of the target frequency spectrum is determined to be not lifted, and then the resource occupation condition of the target frequency spectrum can be determined to be idle.
Further, determining the resource occupation condition of the target spectrum according to the received power includes:
And B, determining that the resource occupation condition of the target frequency spectrum is occupied if the received power is larger than the preset power threshold value.
When a request to be processed is received, if the received power of the target frequency spectrum is determined to be larger than the preset power threshold after the received power of the target frequency spectrum is compared with the preset power threshold, the received power of the target frequency spectrum is determined to be raised, and then the resource occupation condition of the target frequency spectrum can be determined to be occupied.
In some embodiments, in the process of executing the request to be processed, if it is determined that the received power of the target spectrum is raised, it may be identified whether the spectrum is occupied by the cell that receives the request to be processed; if the cell occupies the frequency spectrum, the receiving power of the target frequency spectrum and the using power of the cell, such as the sending power, are subjected to difference operation, and the operation result of the difference operation is compared with a preset power threshold value.
Further, if the operation result is smaller than or equal to the preset power threshold, it is determined that the target spectrum is occupied by the cell only.
If the operation result is larger than the preset power threshold, the target frequency spectrum is determined to be occupied by the cell and other cells which can share the target frequency spectrum.
Further, if the received power of the target spectrum is raised and the target spectrum is not occupied by the cell, it may be determined that the target spectrum is occupied by other cells.
The embodiment can monitor the shared spectrum in real time to obtain the resource occupation condition of the shared spectrum, is convenient for carrying out resource scheduling of the shared spectrum on the request to be processed according to the resource occupation condition, does not need to exchange scheduling information in a mode of high-level signaling among cells, and can shorten the processing period of spectrum sharing.
Fig. 3 is a third flowchart of a spectrum sharing method according to an embodiment of the present application. Referring to fig. 3, in one embodiment, performing resource scheduling of a target spectrum for a request to be processed according to a resource occupancy, includes:
Step S201, determining a target spectrum sharing mode from all spectrum sharing modes if the resource occupation condition is occupied;
When the resource occupation condition of the target spectrum is determined to be occupied, the spectrum sharing mode identifier carried by the cell corresponding to the request to be processed can be obtained. The spectrum sharing mode identifier in this embodiment may include a priority preemption mode identifier, an allocation proportion preemption mode identifier, and a balanced rollback mode identifier.
Further, the spectrum sharing mode identification can be used for determining a target spectrum sharing mode from the spectrum sharing modes.
The spectrum sharing modes in this embodiment may include a priority preemption mode, an allocation proportion preemption mode, a balanced rollback mode, and other spectrum sharing modes. And each spectrum sharing mode can be correspondingly provided with a spectrum sharing mode identifier.
For example, the priority preemption mode, the allocation proportion preemption mode and the balance rollback mode can be respectively provided with a priority preemption mode identifier, an allocation proportion preemption mode identifier and a balance rollback mode identifier.
The preemption mode of the priority may be: the priority of different cells is preset, and after the cells with high priority detect that the shared spectrum has conflict through the shared spectrum monitoring module, the shared spectrum is continuously used; after detecting that the shared spectrum has conflict through the shared spectrum monitoring module, the cell with low priority gives out the shared spectrum with the conflict part, randomly maintains the conflict mechanism, and restores the normal state after a certain number of Slot time set in advance according to the requirement.
The allocation proportion preemption mode can be as follows: different cells can occupy the maximum proportion of the shared spectrum respectively, for example, 60% of cell 1 and 40% of cell 2, which are preset. After the cell detects that the shared spectrum has conflict through the shared spectrum monitoring module, the cell determines whether to preempt or yield the shared spectrum according to the proportion and the distribution proportion of the shared spectrum which are occupied currently. If the occupied proportion of the shared spectrum of the cell is smaller than the allocation proportion, continuing to use the shared spectrum; if the occupied proportion of the shared spectrum of the cell is larger than the allocation proportion, the occupied proportion exceeding the shared spectrum is yielded, the conflict mechanism is maintained randomly, and the normal state is restored after a certain number of Slot time set in advance according to the requirement.
The balanced rollback mode may be: after detecting that the shared spectrum has conflict through the shared spectrum monitoring module, backing back the shared spectrum yielding the conflict, randomly maintaining a conflict mechanism and after a certain number of Slot time preset according to the requirement, if determining that the new free exclusive spectrum or the shared spectrum exists, scheduling to use the new free spectrum; if no newly released idle spectrum exists, the original conflicting shared spectrum is tried to be used, whether the conflict exists is detected through a shared spectrum monitoring module, if the conflict exists, the shared spectrum is used continuously, if the conflict exists, the conflicting shared spectrum is backed back, a conflict mechanism is maintained randomly, and after a certain number of Slot time preset according to the requirement, the normal state is restored.
Step S202, scheduling the resources of the target spectrum for the request to be processed according to the target spectrum sharing mode.
After the target spectrum sharing mode is determined, if the target spectrum sharing mode is a priority preemption mode, performing resource scheduling of the target spectrum according to the priority preemption mode by using an NR100M scheduling module, and executing the request to be processed according to a spectrum resource scheduling result of the NR100M scheduling module by using an NR100M transceiver module. The process of scheduling the resources of the target spectrum according to the priority preemption mode for the request to be processed may refer to the definition of the priority preemption mode, which is not specifically described in this embodiment.
After the target spectrum sharing mode is determined, if the target spectrum sharing mode is an allocation proportion preemption mode, performing resource scheduling of the target spectrum on the request to be processed according to the allocation proportion preemption mode through an NR100M scheduling module, and executing the request to be processed according to a spectrum resource scheduling result of the NR100M scheduling module through an NR100M receiving and transmitting module. The process of scheduling the resources of the target spectrum for the request to be processed according to the allocation ratio preemption mode may refer to the definition of the allocation ratio preemption mode, which is not specifically described in this embodiment.
After the target spectrum sharing mode is determined, if the target spectrum sharing mode is a balanced rollback mode, performing resource scheduling of the target spectrum according to the request to be processed by using an NR100M scheduling module according to the balanced rollback mode, and executing the request to be processed according to a spectrum resource scheduling result of the NR100M scheduling module by using an NR100M transceiver module. The process of performing the resource scheduling of the target spectrum according to the balanced backoff mode for the request to be processed may refer to the definition of the balanced backoff mode, which is not specifically described in this embodiment.
Further, determining a target spectrum sharing mode from the spectrum sharing modes includes:
Step S2011, obtaining a spectrum sharing mode identifier of a cell corresponding to a request to be processed;
When determining the target spectrum sharing mode from the spectrum sharing modes, a spectrum sharing mode identifier can be set for each cell in advance, so that the spectrum sharing mode identifier of the cell sending the request to be processed can be obtained, and the target spectrum sharing mode can be determined from the spectrum sharing modes according to the spectrum sharing mode identifier of the cell.
In step S2012, a target spectrum sharing method is determined from the spectrum sharing methods according to the spectrum sharing method identification.
After the spectrum sharing mode identifiers of the cells sending the request to be processed are obtained, since each spectrum sharing mode identifier is provided with a spectrum sharing mode in advance correspondingly, the spectrum sharing mode identifier of the cell sending the request to be processed, which corresponds to the spectrum sharing mode identifier of the cell sending the request to be processed, can be searched from all the spectrum sharing modes according to the corresponding relation between the spectrum sharing mode identifiers and the spectrum sharing modes, and the searched spectrum sharing mode is determined as a target spectrum sharing mode.
According to the method and the device, the resource scheduling of the shared spectrum can be carried out on the request to be processed through a plurality of spectrum sharing modes such as a priority preemption mode, a distribution proportion preemption mode and a balanced rollback mode, so that spectrum sharing conflict can be avoided, and spectrum sharing efficiency is improved.

Referring to fig. 4 and 5, in one embodiment, each of the communication base stations of the cell 1 and the cell 2 includes an NR100M scheduling module, a shared spectrum monitoring module, and an NR100M transceiver module.
The shared spectrum monitoring module can receive the shared spectrum signals in real time, determine the service condition of the shared spectrum according to the shared spectrum signals and send the service condition to the NR100M scheduling module, and the NR100M scheduling module schedules the use of the idle shared spectrum according to the service condition of the shared spectrum and sends the scheduling result to the NR100M receiving and sending module. And the NR100M transceiver module transmits data according to the air interface spectrum resources scheduled in the scheduling result.
Specifically, when the cell 1 and the cell 2 need to transmit data, the NR100M transceiver module may be preferentially used to transmit data through the exclusive spectrum of the cell in the new air interface resource.
When the resources of the exclusive spectrum of the cell are used up, the resource occupation condition of the shared spectrum in the new air interface resources, which is monitored by the shared spectrum monitoring module, is combined with the NR100M scheduling module to carry out resource scheduling, the NR100M scheduling module indicates the NR100M receiving and transmitting module according to the scheduling result, and the NR100M receiving and transmitting module transmits data according to the scheduling result.
