Description
Technical Field
The embodiment of the application relates to the field of 5G mobile communication, in particular to a base station resource scheduling method, communication equipment and a storage medium.
Background
The bandwidth of the 5G New air interface (NR) mobile communication system is greatly enlarged compared with the maximum 20M bandwidth of the 4G long term evolution (Long Term Evolution, LTE) system, and can reach 100M and be 5 times of that of the 4G mobile communication system. The commercial terminal does not support various bandwidths of 5G NR in one step, but is realized gradually; and the evolution strategies of the terminals in different systems are different: for example, a time division duplex (Time Division Duplexing, abbreviated as TDD) terminal supports a large bandwidth of 100M and then supports a small bandwidth of 20M, and a frequency division duplex (Frequency Division Duplexing, abbreviated as FDD) terminal supports a small bandwidth of 10M and 20M and then supports a large bandwidth of 50M. Taking a 5G NR FDD commercial terminal as an example, the terminal supports small bandwidths of 10M, 20M and the like, and only supports a small amount of 40M bandwidth until the present; in order to cope with the access of terminals supporting different bandwidth capabilities to a 5G mobile communication network, a base station needs to realize the function of being compatible with various terminals. Protocol organization realizes data communication for different Bandwidth capability terminals accessing the same base station, and proposes a partial Bandwidth part (BWP) solution, namely, different BWP frequency domain resources are configured for different Bandwidth terminals accessing the base station.
As shown in fig. 1, the base station has an operating bandwidth of 40M, and can support 40M and 20M terminal access. The base station configures 20M-specific BWP for the accessed 20M terminal and configures 40M-specific BWP for the accessed 40M terminal. When the subcarrier Spacing (SCS) is 15KHz, the 20M dedicated BWP includes 106 Resource Blocks (RBs), and the 40M dedicated BWP includes 216 RBs.
For a 20M terminal, since the downlink synchronization of the terminal depends on the broadcast information sent by the base station, the frequency domain Resource of the synchronization signal block (Synchronization Signal Block, abbreviated as SSB) used by the broadcast information is 240 fixed Resource Elements (REs), that is, 20 RBs, and compared with 216 RBs with 40M full bandwidth, the SSB of the base station cannot occupy the full bandwidth. To match the ability of a 20M terminal to search for base station SSBs, the SSB frequency domain location broadcast by the base station can only be located for a certain segment of contiguous 20 RBs in the 40M bandwidth. The RB resources of the rest part of the cell working bandwidth are not applied to SSB, so that the 20M terminal cannot search the RB resources of the rest part of the cell working bandwidth; meanwhile, the uplink synchronization of the terminal depends on a common physical uplink control channel (Physical uplink control channel, PUCCH for short) to feed back an acknowledgement character (Acknowledge character, ACK for short) of the access signaling; when the operating bandwidth of the base station is greater than or equal to 2 times 20M, the maximum uplink initial BWP configured by the base station can be only 20M. In combination with protocol limitation, in this scenario, two 20M terminals located at two ends of the base station working bandwidth cannot use the common PUCCH RB resource in the same 20M uplink initial BWP, and complete radio resource control (Radio Resource Control, abbreviated as RRC) signaling ACK feedback, so that the 20M terminal can only use a section of continuous 20M resource in the base station working bandwidth, and the remaining bandwidth resource base station cannot be scheduled for the 20M terminal to use.
In summary, when the base station operating bandwidth is greater than or equal to 2 times of the terminal supporting bandwidth, if the terminals accessing the base station are mostly terminals supporting small bandwidths, only a small part of the base station operating bandwidth is used frequently, the frequency of using the whole bandwidth is relatively low, and the frequency spectrum use rate of the base station operating bandwidth is low as a whole.

Detailed Description
For the purpose of making the objects, technical solutions and advantages of the embodiments of the present application more apparent, the embodiments of the present application will be described in detail below with reference to the accompanying drawings. However, as will be appreciated by those of ordinary skill in the art, in the various embodiments of the present application, numerous technical details have been set forth in order to provide a better understanding of the present application. However, the technical solutions claimed in the present application can be implemented without these technical details and with various changes and modifications based on the following embodiments. The following embodiments are divided for convenience of description, and should not be construed as limiting the specific implementation of the present application, and the embodiments may be mutually combined and referred to without contradiction.
One embodiment of the present application relates to a base station resource scheduling method, applied to a base station, as shown in fig. 2, including:
In an example implementation, the preset terminal bandwidth requirement classification refers to a class of bandwidth requirements of a terminal to which the base station accesses, for example, the terminal accessing the base station includes a 10M terminal, a 20M terminal, a 30M terminal, and the like; after the obtained terminal bandwidth requirements are classified, the base station divides the bandwidth resources of the base station into resource blocks with different bandwidth requirements according to different bandwidth requirements.
In an example implementation, assume that the types of terminals accessing the base station are 10M terminals, 15M terminals, 20M terminals, mM terminals, and full bandwidth terminals, totaling m+1 types; as shown in fig. 3, the manner of classifying and dividing the resource blocks by the base station according to the bandwidth requirement of the terminal includes: mode 1, dividing a bandwidth resource of a base station into a resource block; mode 2, dividing the bandwidth resource of the base station into a plurality of resource blocks with the same bandwidth resource; mode 3, dividing the bandwidth resource of the base station into a plurality of resource blocks with different bandwidth resources; wherein, mode 1 is aimed at the terminal with the same bandwidth requirement as the base station working bandwidth resource, mode 2 and mode 3 are aimed at the terminal with the bandwidth requirement smaller than the base station working bandwidth resource, when the terminal admitted by the base station cell is a certain fixed bandwidth requirement, mode 2 can be adopted, when the bandwidth requirements of the terminals admitted by the base station are different, mode 3 can be adopted; the same resource blocks are divided in the mode 2 and the mode 3, which considers that the terminals accessed by the base station have a certain condition that the quantity of the bandwidth demand terminals is large in proportion, so that the bandwidth demand terminals are ensured to have relatively better service than different bandwidth demand terminals accessed by other base stations.
It should be noted here that: in one base station, the bandwidth resources of the base station may be divided in the division manners of the modes 1, 2 and 3, but the bandwidth resources occupied by the resource blocks divided in different manners are multiplexed in the frequency domain.
In an example implementation, the total number of resource blocks after bandwidth resource partitioning of the base station needs to satisfy the following limitations: (1) The number of resource blocks needs to be greater than or equal to the requirement of the resource blocks required by the synchronization signal block of the base station (i.e., the number of resource blocks needs to be greater than 20); (2) The number of resource blocks needs to meet the requirements of a group of physical resource sets CoreSet0 of the base station (as shown in table 1, when the subcarrier spacing is 15KHz, the number of resource blocks is not less than 24); (3) The number of resource blocks needs to meet the requirements of the broadcast message of the base station.
TABLE 1 CoreNet 0 requirement of base station at 15KHz subcarrier spacing
In an example implementation, step 102 may be implemented by the sub-steps shown in fig. 4, including:
sub-step 1021, initializing a resource block information array, and writing bandwidth configuration information of each resource block into the resource block information array.
In an example implementation, before associating each resource block with each logical cell, it is necessary to initialize the resource block information array FreqRB [ ] and the initialized resource block information array Index index=0, then sequentially read the bandwidth configuration information of the resource blocks, write the configuration information of the resource blocks into FreqRB [ Index ], and add the value of Index to 1, and read the bandwidth configuration information of the next resource block until the configuration information of all the resource blocks is written into the initialized resource block information array FreqRB [ ].
In an example implementation, each logical cell configures the unique initial bandwidth configuration information (i.e., initial BWP). The downlink initial BWP configures resources such as CoreSet0 and SSB. The uplink initial BWP configures resources such as a common physical uplink control channel (Physical Uplink Control Channel, abbreviated as PUCCH) and a physical random access channel (Physical Random Access Channel, abbreviated as PRACH) of each. The bandwidth of the initial BWP may be consistent with the bandwidth of the resource block, but cannot be greater than the resource block bandwidth. Each logical cell configures respective dedicated bandwidth configuration information (i.e., dedicated BWP) for use by the post-access scheduling of the terminal, the dedicated BWP bandwidth being required to be consistent with the resource block bandwidth.
In an example implementation, each logical cell has a corresponding logical cell configuration array logicccellinfo [ ] and a logical cell configuration data index lcellndex, and before the association of the logical cell and the resource block is performed, it is also necessary to initialize the logical cell configuration array logicccellinfo [ ] and the logical cell configuration data index lcellndex=0; for each of the logical cells, taking logical cell 1 as an example (i.e., lcellindex=1), the initial bandwidth configuration information of logical cell 1 is written into the logical cell configuration array (i.e., logiccllinfo [ LCellIndex ] - > BWP- > InitialBWPCfg), and then the dedicated bandwidth configuration information is written into the logical cell configuration array logiccllinfo [ LCellIndex ] (i.e., logiccllinfo [ LCellIndex ] - > BWP- > dediedbwpcfg); and then, according to the initial bandwidth configuration information and the special bandwidth configuration information of the logic cell 1, bandwidth configuration information of a resource block which is smaller than or equal to the initial bandwidth configuration information and equal to the special bandwidth configuration information is found out from the resource block information data, and the determined bandwidth configuration information of the resource block is associated with the logic cell 1 (namely LogicCellInfo [ LCelIndex ] - > BW- > FreqRB [ Index ]), so that the association of the logic cell and the resource block is completed.
In an example implementation, after associating the logical cell with its corresponding resource block, the broadcast message configuration of the master information block (Master Information Block, abbreviated MIB), the remaining minimum system information (Remaining Minimum System Information, abbreviated RMSI), the remaining system information (Other System Information, abbreviated OSI) and the like of the logical cell, i.e., logicecellfo [ LCellIndex ] - > MIB, logicCellInfo [ LCellIndex ] - > RMSI, logicCellInfo [ LCellIndex ] - > OSI, is also completed. After the configuration of one logical cell is completed, the value of LCellIndex is increased by 1, and the processing of the next logical cell is started.
And step 103, associating each logic cell to a physical cell of the base station, so that when the physical cell receives the bandwidth requirement reported by the terminal, the terminal is accessed to the logic cell corresponding to the bandwidth requirement of the terminal, and bandwidth resources on a resource block associated with the logic cell are scheduled for the terminal to use.
In an example implementation, the Physical cell is configured to generate a cell downlink signal of the base station, where the generated cell downlink signal includes a unique Physical-layer Cell identity (PCI for short), so as to ensure that the terminal can only search for the PCI during downlink synchronization, so that the terminal communicates with the base station through the Physical cell corresponding to the PCI.
In an example implementation, after each logical cell is associated with each resource block, each logical cell needs to be associated with the same physical cell, as shown in fig. 5, the correspondence between each logical cell and each resource block is one-to-one, and the correspondence between each logical cell and each physical cell is many-to-one; after each logical cell is associated with the physical cell, the configuration of the broadcast message of the physical cell needs to be completed, and the configuration of the broadcast message of the physical cell is associated with the configuration of the broadcast message of the full bandwidth logical cell.
It should be noted here that each logical cell has a respective broadcast message. Multiple logical cells simultaneously transmit broadcast messages, which occupies a large amount of bandwidth resources and wastes resources. If the base station in fig. 5 only accesses the 10M terminal and the 20M terminal, then the broadcast message of the logical cell 2 is sent, that is, the bandwidth frequency domain resource of the physical cell 108 is consumed unnecessarily; therefore, the broadcast message configuration of the physical cell is related to the broadcast message configuration of the full-bandwidth logical cell, so that the physical cell can fixedly send the broadcast message of the full-bandwidth logical cell, and the broadcast messages of other logical cells are not sent temporarily. When the terminal sends the bandwidth requirement to the physical cell, the physical cell acquires the bandwidth requirement of the terminal and then additionally transmits the broadcast message of the logical cell matched with the bandwidth requirement.
In an example implementation, after receiving a bandwidth requirement reported by a terminal, a physical cell obtains a logical cell matched with the bandwidth requirement from each logical cell associated with the physical cell, and issues a broadcast message of the logical cell, so that the terminal accesses the determined logical cell, and after accessing the logical cell, the terminal can schedule bandwidth resources of resource blocks associated with the logical cell for the terminal to use.
In the embodiment of the application, in the process of resource scheduling of a base station, according to the preset terminal bandwidth demand classification, dividing the bandwidth resource of the base station into resource blocks with various bandwidth demands; according to the bandwidth configuration information of each resource block and the bandwidth configuration information of each logic cell of the base station, associating each resource block with each logic cell of the base station; each logic cell is associated to a physical cell of a base station, so that when the physical cell receives the bandwidth requirement reported by a terminal, the terminal is accessed to the logic cell corresponding to the bandwidth requirement of the terminal, and bandwidth resources on a resource block associated with the logic cell are scheduled for the terminal to use; the bandwidth resources of the base station are divided into resource blocks with different bandwidths, and the resource blocks are scheduled for the terminals with different bandwidth demands, so that the base station can reasonably divide and configure the bandwidth resources, the effect of being compatible with the terminals with different bandwidth capacities is achieved, the situation that the bandwidth resources of the base station cannot be scheduled for the terminals is avoided, and the use efficiency of the bandwidth resources of the base station is improved; the technical problem of low frequency spectrum utilization rate of the working bandwidth of the base station in the prior art is solved.
One embodiment of the present application relates to a base station resource scheduling method, applied to a physical cell of a base station, as shown in fig. 6, including:
In an example implementation, the physical cell issues a full bandwidth broadcast message, and after monitoring the broadcast message issued by the physical cell, the terminal reports a bandwidth requirement to the physical cell, where the reported bandwidth requirement may be 10M, 20M, 30M, and so on.
In an example implementation, the physical cell obtains, among the associated logical cells, a logical cell that meets the needs of the terminal. As shown in fig. 5, resource block 1 associated with logical cell 1 and resource block 2 associated with logical cell 2 of the physical cell schedule terminals supporting 10M bandwidth capability and 15M bandwidth capability, respectively; finding a logic cell meeting the bandwidth requirement of the terminal according to the bandwidth capability supported by the resource blocks associated with each logic cell and the bandwidth requirement of the terminal
And 203, issuing a broadcast message of the logic cell for the terminal to access the logic cell.
In an example implementation, after a logical cell satisfying the bandwidth requirement of the terminal is determined, a broadcast message of the determined logical cell is issued, and the terminal accesses the logical cell after receiving the broadcast message of the logical cell.
In an example implementation, after a terminal accesses a determined logical cell, bandwidth resources required by the terminal may be obtained from resource blocks associated with the logical cell for use by the terminal.
In an example implementation, terminals supporting the same capability are scheduled sequentially on different resource blocks in the event that the bandwidth resources of the base station are sufficient. As shown in fig. 5, the physical cell may schedule terminals supporting 20M bandwidth requirements using resource block 3 associated with logical cell 3 and resource block 4 associated with logical cell 4. When a plurality of 20M terminals are accessed to the network, the physical cell sequentially uses the resource block 3 associated with the logical cell 3 and the resource block 4 associated with the logical cell 4 to provide services for the terminals, so that the service performance of the terminals is ensured to the maximum extent, and the bandwidth resource utilization rate is improved.
In an example implementation, when the logical cells matching the bandwidth requirements of the terminal include n (n is greater than 1), the terminal may be accessed to the logical cells with high priority according to the preset access priorities of the n logical cells; and when the number of the access terminals of the logic cells with high priority reaches a preset threshold, accessing the terminal into the logic cells with secondary priority.
In an example implementation, when the idle bandwidth resources of the resource blocks associated with the logical cells accessed by the terminal are insufficient, the bandwidth resources on the resource blocks associated with the logical cells with the idle bandwidth resources in each logical cell can be used by the terminal; as shown in fig. 5, when the bandwidth resources of the resource block 3 associated with the logical cell 3 are insufficient, idle bandwidth resources can be acquired from other logical cells for the terminal accessing the logical cell 3 to use; and triggering and recycling idle logic cell resources used by the non-terminal for the logic cell use accessed by the terminal so as to improve the service performance and the service perception capability of the admission terminal.
In an example implementation, after terminals with different bandwidth requirements access the base station, there is a case where the scheduling resource blocks overlap. As shown in fig. 5, resource block 0 associated with logical cell 0 of the physical cell is a full bandwidth resource, and resource block 0 and other resource blocks overlap. When terminals supporting different bandwidth demands are scheduled, based on a minimum guarantee rate (PBR) strategy, if the number of small bandwidth demand terminals is obviously more than that of large bandwidth demand terminals from the viewpoint of supporting the number of different bandwidth terminals, the small bandwidth demand terminals can be scheduled preferentially, and then the large bandwidth demand terminals are scheduled; considering the bandwidth requirement of each terminal, the large bandwidth requirement terminal needs more resources, and the large bandwidth requirement terminal can be scheduled preferentially, and then the small bandwidth requirement terminal is scheduled, so that the service performance of the terminal is ensured to be maximized.
According to the embodiment of the application, the bandwidth resources of the base station are divided into the resource blocks with different bandwidths, when the physical cell receives the bandwidth demands of the terminal, the bandwidth resources of the resource blocks matched with the bandwidth demands are scheduled for the terminal to use, so that the base station can reasonably divide and configure the bandwidth resources, the effect of being compatible with the terminals with different bandwidth capacities is achieved, the situation that the bandwidth resources of the base station cannot be scheduled for the terminal to use is avoided, and the use efficiency of the bandwidth resources of the base station is improved; the technical problem of low frequency spectrum utilization rate of the working bandwidth of the base station in the prior art is solved.
The above steps of the methods are divided, for clarity of description, and may be combined into one step or split into multiple steps when implemented, so long as they include the same logic relationship, and they are all within the protection scope of this patent; it is within the scope of this patent to add insignificant modifications to the algorithm or flow or introduce insignificant designs, but not to alter the core design of its algorithm and flow.
The implementation of the technical solution of the present application is described in further detail below by taking the example that the bandwidth resource of the base station is 40M:
(1) Assuming that the base station only accesses terminals supporting bandwidths of 20M and 40M, as shown in fig. 7, the bandwidth resources of the base station are divided into resource block 1 (full bandwidth) and resource block 2 (high frequency 20M).
(2) And associating the logic cell 1 with the resource block 1 according to the configuration information of each resource block and the configuration information of each logic cell, and associating the logic cell 2 with the resource block 2. The initial bandwidth configuration information (initial BWP) of the logical cell 1 is located at the position indicated by the broken line in fig. 7, and is the low frequency 20M of the physical cell 106, the initial bandwidth configuration information (initial BWP) of the logical cell 2 coincides with the resource block associated with the logical cell 2, and is the high frequency 20M of the physical cell 106. The dedicated bandwidth configuration information (dedicated BWP) of logical cell 1 configures 2, one being a 20M dedicated BWP for providing a service to the 20M terminal and the other being a 40M dedicated BWP for providing a service to the 40M terminal. Wherein the 20M dedicated BWP and the initial bandwidth configuration information (initial BWP) of the logical cell 1 use the same frequency domain resource. The dedicated bandwidth configuration information (dedicated BWP) of the logical cell 2 configures only one, which is 20M dedicated BWP, using the same frequency domain resource as the initial bandwidth configuration information (initial BWP) of the logical cell 2. Logical cell 1 and logical cell 2 have respective broadcast messages. The cell bandwidth broadcasted by logical cell 1 is 40M and the cell bandwidth broadcasted by logical cell 2 is 20M (or 40M). The configuration information of logical cell 1 and logical cell 2 is shown in table 2:
table 2 configuration information of logical cell 1 and logical cell 2
(3) Logical cell 1 and logical cell 2 are associated to physical cell 106 and the broadcast message configuration of physical cell 106 is associated to the broadcast message configuration of logical cell 1.
(4) Before the physical cell 106 issues the broadcast message, the low frequency 20M terminal access terminal counter c1=0, the high frequency 20M terminal access terminal counter c2=0, and the 40M terminal access terminal counter c3=0 are initialized; setting an Active40 NumThld=TM of a 40M terminal activation number threshold; setting a logic cell 1 access terminal quantity threshold triggerofnum=m for triggering and issuing a logic cell 2 broadcast message; initializing a logic cell 2 broadcast message issuing Flag c2_flag=0; after the above operation is completed, the broadcast message of the logical cell 1 (logical cell 1 bw=40m, full bandwidth) starts to be issued.
(5) As shown in fig. 8, when the physical cell receives the bandwidth requirement reported by the terminal, it first determines whether the terminal supports 40M bandwidth according to the bandwidth requirement of the terminal, when the terminal supports 40M terminal, the value of the 40M terminal access terminal counter C3 is increased by 1, and the terminal is issued with the 40M special BWP configuration of the logical cell 1, and then the subsequent terminal access process is entered.

And judging whether the number C1 of the 20M terminals admitted by the logical cell 1 is equal to the terminal number threshold M configured by the operator client, so as to realize the admission of the 20M terminals by the logical cell 2. Meanwhile, the resource of the logic cell 2 is triggered and recovered by combining the number threshold of the 40M terminals received by the physical cell, and the resource is used for guaranteeing the service of the 20M terminals and the 40M terminals of the logic cell 1. It should also be noted that the premise of the logical cell 2 admitting the 20M terminal is to issue a broadcast message of the logical cell 2, and at the same time, a method of redirecting the 20M terminal of the pre-attached logical cell 1 to the logical cell 2 is adopted.
