Resource allocation method, electronic device, apparatus and storage medium

Technical Field

The present disclosure relates to the field of wireless communications technologies, and in particular, to a resource allocation method, an electronic device, an apparatus, and a storage medium.

Background

In a mobile communication system, in an indoor distribution system or a high-speed scene, the coverage radius of each remote radio unit (Remote Radio Unit, RRU) is smaller, the cell reselection switching frequently occurs due to the movement of a terminal, the communication quality is seriously influenced, and the method is to enlarge the coverage range of a cell. The cell merging is to merge the baseband signals of remote devices (RRUs) installed at different Base station sites into one cell by using optical fibers and merge the physical cells into one cell by a baseband processing Unit (BBU), so as to enlarge the coverage area of the cell. The adoption of cell combination can bring the following benefits: the switching, the call drop rate and the neighbor relation are reduced, different physical cells can be allowed in one logic cell, the network structure is selectively adjusted, and the network expansion and coverage are more flexibly carried out.

The 5G distributed indoor scene adopts a multi-point PICO (PICO base station) remote merging mode based on Radio Hub (RHIB), and reduces the cost of RRU and the product cost while obtaining the cell merging gain. In this scenario, the existing mode is adopted to schedule and allocate resources to the terminal based on the service priority of the terminal, if the situation that the PICO to which a plurality of terminals belong in the frequency division scheduling scenario is different exists, the RHOB will bring obvious noise rise after merging the time domain or frequency domain signals of the PICO of a plurality of points, and has great influence on the cell capacity. Therefore, how to propose a resource allocation method to effectively inhibit the noise rise caused by multi-point PICO signal combination is an important issue to be solved in the industry.

Detailed Description

In the embodiment of the application, the term "and/or" describes the association relationship of the association objects, which means that three relationships may exist, for example, a and/or B may be represented: a exists alone, A and B exist together, and B exists alone. The character "/" generally indicates that the context-dependent object is an "or" relationship.

The term "plurality" in the embodiments of the present application means two or more, and other adjectives are similar thereto.

The following description of the technical solutions in the embodiments of the present application will be made clearly and completely with reference to the accompanying drawings in the embodiments of the present application, and it is apparent that the described embodiments are only some embodiments of the present application, but not all embodiments. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure.

In a 5G distributed indoor scene, cell merging is realized by adopting a multi-point PICO remote merging mode based on RHOB, after the PICO receives time-frequency domain data sent by a terminal, the data is transmitted to the RHOB, the RHOB carries out digital signal merging on time domain or frequency domain digital signals of a plurality of PICO corresponding channels, and then the digital signals are transmitted to a BBU side for processing.

Fig. 1 is a schematic diagram of PICO signal combination provided in the embodiment of the present application, as shown in fig. 1, a plurality of RHUB may adopt a multi-stage serial connection manner, where a PICO input by RHUB combination is defined as a physical PICO, and an output after RHUB combination is named as a logical PICO. Assuming that the logical PICO is named as P (N) (where N is an index, n=1, 2, …, N is the number of logical PICOs), the logical PICOs merge the input M physical PICOs, each of which is named as P (N, M) (where the range of values of M is 1,2, …, M is the number of physical PICOs each of which merges the input. In fig. 1, nmax is 4 and mmax is 8.

As shown in fig. 1, if the RHUB performs signal combination on the physical PICO signals of the plurality of physical PICO signals, that is, for each time slot, the RHUB performs signal combination on the physical PICO to which all terminals scheduled by each frequency domain resource in the time slot belong, it is required that all users scheduled by frequency division in the time slot must belong to the same physical PICO, so that the combining gain can reach the maximum (that is, the effect of suppressing noise is the best). However, in the existing mode of scheduling the terminals and distributing resources based on the service priority of the terminals, if the physical PICO to which a plurality of terminals belong in a frequency division scheduling scene is different, after the RHIB performs time domain physical PICO signal combination, the base noise of the logic PICO is raised, and the cell capacity is greatly affected.

Aiming at the problems, the embodiments of the application provide a solution, which can effectively inhibit the bottom noise rise caused by multi-point PICO signal combination by adjusting the scheduling terminal set of each time slot on the premise of not influencing the terminal scheduling service and not wasting scheduling resources, thereby improving the capacity of uplink and downlink transmission of a cell.

Fig. 2 is a flow chart of a resource allocation method provided in an embodiment of the present application, where the method may be applied to a network device (e.g., a base station or a BBU in a base station), and as shown in fig. 2, the method includes the following steps:

step 200, determining a first terminal set, wherein the first terminal set is a set of terminals with frequency domain resources allocated to a target time slot;

specifically, for the mode of time domain transmission between the current RHIB and BBU, different frequency domain resources in each time slot can schedule different terminals, in order to effectively inhibit the background noise rise caused by multi-point PICO signal combination, in the embodiment of the application, when time domain and frequency domain resources are allocated to the terminals, cooperative scheduling is performed for the physical PICO attribution result of each terminal, and the terminals to which the same physical PICO is attributed are scheduled in each time slot as much as possible.

Therefore, when terminal scheduling and resource allocation are performed for a target time slot (which can be understood as any time slot), after each scheduling terminal is determined and corresponding frequency domain resources are allocated, the terminal can be added into the first terminal set, so that when the next scheduling terminal is determined, the terminal information in the current first terminal set can be referred to, and cooperative scheduling can be performed for the physical PICO attribution result of each terminal.

It should be noted that, when determining the first scheduling terminal of the target time slot may be implemented based on an existing mechanism, for example, a terminal with the highest scheduling priority in the terminals of the resources to be allocated in the time slot may be selected according to the terminal scheduling priority information, and the terminal is determined as the first scheduling terminal of the time slot. Then, corresponding frequency domain resources can be allocated to the first scheduling terminal according to the service data volume requirement, and the first scheduling terminal is added into the first terminal set.

Step 201, determining a target scheduling terminal based on a first physical PICO set corresponding to the first terminal set and terminal scheduling priority information;

specifically, terminal scheduling and resource allocation are performed for the target time slot, after determining the current first terminal set, the network device may determine, according to terminal information attributed under each physical PICO (for example, an index of a terminal attributed under each RHUB combined physical PICO), a first physical PICO set corresponding to the first terminal set, that is, a set of physical PICOs to which a terminal to which a frequency domain resource is currently allocated belongs.

After the first physical PICO set is determined, the network device can combine the information of the first physical PICO set and the terminal scheduling priority information to determine a target scheduling terminal (namely the next scheduling terminal to be determined), so that a plurality of terminals belonging to different physical PICOs can be prevented from being scheduled in the same time slot as much as possible, and the purpose of effectively suppressing the background noise lifting is achieved.

Step 202, according to the service data volume demand of the target scheduling terminal, allocating the corresponding frequency domain resource in the target time slot to the target scheduling terminal.

Specifically, after determining the target scheduling terminal, the network device may allocate, according to the traffic data volume requirement of the terminal, a corresponding frequency domain resource in the target time slot to the terminal from the allocable frequency domain resources remaining in the target time slot.

According to the resource allocation method provided by the embodiment of the invention, when terminal scheduling and resource allocation are carried out on a target time slot, the target scheduling terminal is determined by combining the physical PICO information and the terminal scheduling priority information of the terminal to which the current allocated frequency domain resource belongs, so that a plurality of terminals belonging to different physical PICO can be prevented from being scheduled on the same time slot as much as possible, the background noise rise caused by multi-point PICO signal combination can be effectively restrained, and the uplink and downlink transmission capacity of a cell is improved.

Optionally, determining the target scheduling terminal based on the first physical PICO set corresponding to the first terminal set and the terminal scheduling priority information includes:

and determining the target scheduling terminal based on the residual frequency domain resource information in the target time slot, the first physical PICO set corresponding to the first terminal set and the terminal scheduling priority information.

Specifically, in the embodiment of the present application, when determining the target scheduling terminal, in addition to the first physical PICO set corresponding to the first terminal set and the terminal scheduling priority information, the remaining frequency domain resource information in the current target time slot may be combined, for example, whether there are remaining allocable frequency domain resources in the current target time slot, or whether all remaining allocable frequency domain resources have to be scheduled, and so on. According to the difference of the residual frequency domain resource information in the target time slot, the target scheduling terminal can be determined in different modes.

Optionally, determining the target scheduling terminal based on the remaining frequency domain resource information in the target time slot, the first physical PICO set corresponding to the first terminal set, and the terminal scheduling priority information includes:

if the fact that the remaining allocable frequency domain resources exist in the target time slot is determined, a second terminal set is determined based on a first physical PICO set corresponding to the first terminal set, wherein the second terminal set is a set of terminals meeting a first condition and/or a second condition in terminals of the frequency domain resources to be allocated in the target time slot;

Specifically, in the embodiment of the present application, when determining the target scheduling terminal, it may first determine whether there are remaining allocable frequency domain resources in the target time slot.

If it is determined that no allocable frequency domain resources remain in the target time slot, ending the frequency domain resource allocation of the target time slot, and no longer determining the target scheduling terminal.

If it is determined that there are remaining allocable frequency domain resources in the target time slot, a second terminal set may be determined according to information of a first physical PICO set corresponding to the first terminal set, where the second terminal set refers to a set of terminals satisfying the first condition and/or terminals satisfying the second condition among terminals to be allocated with the frequency domain resources in the target time slot. After the second terminal set is determined, determining the target scheduling terminal based on the second terminal set and the terminal scheduling priority information.

In one possible implementation, the first condition may be: the physical PICO to which the terminal belongs is the physical PICO in the first physical PICO set. That is, each terminal belonging to each physical PICO in the first physical PICO set may be selected to join the second terminal set (it may be understood that the selected terminal should be a terminal to which the frequency domain resource is to be allocated for the target time slot), and if the target scheduling terminal is determined from the second terminal set, since the physical PICO to which the target scheduling terminal belongs already exists in the first physical PICO set, the newly added scheduling terminal will not cause background noise rise.

In one possible implementation, the second condition may be: the RHIB corresponding to the physical PICO to which the terminal belongs is other RHIB except the RHIB set corresponding to the first physical PICO set. That is, according to the RHUB information corresponding to each physical PICO, a RHUB set corresponding to the first physical PICO set may be determined, then other RHUBs except for the RHUB set may be selected, and all terminals to which the other RHUBs belong under the combined physical PICOs are added to the second terminal set. Since the noise rise is only caused by signal combination of a plurality of physical PICOs combined by the same RHIB, but the noise rise is not caused by signal combination among different RHIBs, after the second terminal set is determined in this way, if the target scheduling terminal is determined from the second terminal set, the newly added scheduling terminal does not cause the noise rise.

Alternatively, the two possible implementations may be combined, i.e. terminals satisfying both the first condition and the second condition are added to the second set of terminals.

Taking the multi-RHUB cascade scenario in fig. 1 as an example, if it is determined that the first physical PICO set includes P (1, 1) and P (2, 2), a terminal to which P (1, 1) and P (2, 2) belong may be selected to join the second terminal set; terminals belonging to the physical PICO combined by RHIB 3 and RHIB 4 can be selected to be added into the second terminal set, namely terminals belonging to P (3, 1), P (3, 2), …, P (3, 8) and P (4, 1), P (4, 2), … and P (4, 8) can be selected to be added into the second terminal set; terminals belonging to P (1, 1), P (2, 2), P (3, 1), P (3, 2), …, P (3, 8) and P (4, 1), P (4, 2), … and P (4, 8) can also be selected to be added into the second terminal set.

According to the resource allocation method provided by the embodiment of the invention, under the condition that the residual allocable frequency domain resources exist in the target time slot, the second terminal set meeting the first condition and/or the second condition is determined according to the information of the first physical PICO set corresponding to the first terminal set, and the target scheduling terminal is determined based on the second terminal set, so that the newly added scheduling terminal cannot bring about background noise lifting, the residual frequency domain resources are fully utilized, background noise lifting can be effectively restrained, and the uplink and downlink transmission capacity of a cell is improved.

Optionally, determining the target scheduling terminal based on the second terminal set and the terminal scheduling priority information includes:

if the second terminal set is not empty, determining a terminal with the highest scheduling priority in the second terminal set as a target scheduling terminal according to the terminal scheduling priority information; or alternatively, the process may be performed,

Specifically, in the embodiment of the present application, after the second terminal set is determined, a terminal with the highest scheduling priority in the second terminal set may be selected as a target scheduling terminal according to the terminal scheduling priority information, so as to perform resource allocation.

Optionally, if the second terminal set is empty, it may be determined whether the remaining allocable frequency domain resources in the target time slot need to be scheduled, and a corresponding terminal scheduling policy is determined according to the determination.

Optionally, determining a corresponding scheduling policy according to whether the remaining allocable frequency domain resources in the target time slot need to be scheduled, including:

if the remaining allocatable frequency domain resources in the target time slot do not need to be scheduled, ending the frequency domain resource allocation of the target time slot; or alternatively, the process may be performed,

If the remaining allocable frequency domain resources in the target time slot need to be scheduled, determining a third terminal set based on a first physical PICO set corresponding to the first terminal set, wherein the third terminal set is a set of terminals meeting a third condition in terminals of the frequency domain resources to be allocated in the target time slot;

optionally, the third condition is: the physical PICO to which the terminal belongs is different from the physical PICO in the first physical PICO set, and the RHIB corresponding to the physical PICO to which the terminal belongs is the RHIB in the RHIB set corresponding to the first physical PICO set.

Specifically, in the embodiment of the present application, if it is determined that the allocable frequency domain resources remaining in the target time slot do not need to be scheduled, the frequency domain resource allocation of the target time slot is ended, and the target scheduling terminal is not determined any more.

If it is determined that the remaining allocable frequency domain resources in the target time slot need to be scheduled, a third terminal set can be determined according to the information of the first physical PICO set corresponding to the first terminal set, where the third terminal set refers to a set of terminals meeting a third condition in terminals to which the frequency domain resources are to be allocated in the target time slot. After the third terminal set is determined, determining the target scheduling terminal based on the third terminal set and the terminal scheduling priority information.

In one possible implementation, the third condition may be: the physical PICO to which the terminal belongs is different from the physical PICO in the first physical PICO set, and the RHIB corresponding to the physical PICO to which the terminal belongs is the RHIB in the RHIB set corresponding to the first physical PICO set.

Taking the multi-RHUB cascade scenario in fig. 1 as an example for illustration, if it is determined that the first physical PICO set includes P (1, 1) and P (2, 2), then terminals belonging to other physical PICOs except P (1, 1) and P (2, 2) combined by RHUB1 and RHUB2 may be selected to join the third terminal set, that is, terminals belonging to P (1, 2), P (1, 3), …, P (1, 8) and P (2, 1), P (2, 3), …, and P (2, 8) may be selected to join the third terminal set.

Alternatively, still referring to the above example, when determining the third terminal set, only one physical PICO different from P (1, 1) may be selected from all the physical PICOs combined by RHUB1, and then the terminal to which the physical PICO belongs may be added to the third terminal set. Similarly, only one physical PICO different from P (2, 2) may be selected from all the physical PICOs corresponding to RHUB2, and then the terminal to which the physical PICO belongs may be added to the third terminal set. It may be appreciated that after the third terminal set is determined in this manner, RHUB corresponding to different physical PICOs in the physical PICO set corresponding to the third terminal set is different.

After the third terminal set is determined, a terminal with the highest scheduling priority in the third terminal set can be selected as a target scheduling terminal according to the terminal scheduling priority information, and resource allocation is performed.

According to the resource allocation method provided by the embodiment of the application, under the condition that the residual allocable frequency domain resources in the target time slot are required to be scheduled, a third terminal set meeting a third condition can be determined according to the information of the first physical PICO set corresponding to the first terminal set, and the target scheduling terminal is determined based on the third terminal set, so that the residual frequency domain resources can be fully utilized.

Optionally, determining the third terminal set based on the first physical PICO set corresponding to the first terminal set includes:

determining an RHIB set corresponding to the first physical PICO set;

for any RHIB in the RHIB set, determining a target physical PICO in the target RHIB combined physical PICO, and adding a terminal belonging to the target physical PICO and to which the frequency domain resource to be allocated belongs to a third terminal set; the target physical PICO is different from the physical PICO in the first set of physical PICO;

Determining based on the number of the physical PICO of the target RHIB combination;

a power determination based on the target RHUB combined physical PICO;

determining the number of the terminals belonging to the physical PICO combined based on the target RHIB;

based on a random selection pattern.

Specifically, in the embodiment of the present application, for the case that RHUB corresponding to different physical PICOs is different in the physical PICO set corresponding to the third terminal set, a possible determination manner of the third terminal set is provided.

For example, a set of RHUB corresponding to the first set of physical PICOs may be first determined, and then, for any RHUB in the set of RHUB, one target physical PICO may be selected from the target RHUB-combined physical PICOs, where the selected one target physical PICO should be different from an existing physical PICO in the first set of physical PICOs. In this way, a target physical PICO can be selected for each RHIB, and then all terminals belonging to the frequency domain resources to be allocated under the selected target physical PICO are added into a third terminal set, so that a third terminal set is obtained, wherein RHIB corresponding to different physical PICAs in the physical PICO set corresponding to the third terminal set is different.

Note that, the above RHUB combined physical PICO refers to a physical PICO that transmits a time domain or frequency domain digital signal to RHUB for combination, for example, in fig. 1, the RHUB1 combined physical PICO includes P (1, 1), P (1, 2), P (1, 3), …, and P (1, 8). The merging may refer to direct superposition of the digital signals of the physical PICOs, or superposition of the digital signals of the physical PICOs after weighting according to the weight coefficients corresponding to the digital signals.

For any RHUB in the RHUB set corresponding to the first physical PICO set, there may be multiple ways to determine the target physical PICO in the target RHUB combined physical PICO, for example: can be determined based on the number of the physical PICO of the target RHIB combination, for example, can be selected according to the sequence of the number; the power determination may also be based on the power determination of the physical PICO combined by the target RHIB, for example, the power may be selected according to the power order, where the power may refer to the current actual power of the physical PICO, and it may reflect the number of terminals to which the current physical PICO belongs; the terminal number of the target RHIB combined physical PICO belonging to can also be determined based on the terminal number of the target RHIB combined physical PICO, for example, the terminal number can be selected according to the order of the terminal numbers; or may be determined in a randomly selected manner.

Optionally, the method further comprises:

if the third terminal set is empty, determining a new target physical PICO according to a determination mode of the target physical PICO, and adding the terminal to be allocated with the frequency domain resource attributed under the new target physical PICO into the third terminal set.

Specifically, in this embodiment of the present application, if the third terminal set is empty, that is, no terminal is determined according to the above manner of determining the third terminal set, the new target physical PICO may be determined again according to the above manner of determining the target physical PICO, for example, based on the number of the target RHUB combined physical PICO, or based on the power of the target RHUB combined physical PICO, or based on the number of terminals to which the target RHUB combined physical PICO belongs, or based on a random selection manner, and then, the terminal to which the frequency domain resource to be allocated to which the new target physical PICO belongs is added to the third terminal set, so as to obtain the third terminal set that is not empty.

Specifically, in the embodiment of the application, after each scheduling terminal is determined and frequency domain resources are allocated to the terminal, the terminal is added into the first terminal set so as to update the first terminal set in time, and reference information is provided for selecting the next scheduling terminal, so that a plurality of terminals belonging to different physical PICO can be avoided from being scheduled in the same time slot as much as possible, and the purpose of effectively suppressing bottom noise lifting is achieved.

Specifically, in the embodiment of the present application, in order to facilitate terminal scheduling and resource allocation according to the correspondence between the terminal, the physical PICO, and the RHUB, an index of the terminal to which each RHUB belongs under the physical PICO combined may be pre-established.

For example, an index of terminals to which the merged physical PICO belongs may be established for each RHIB, assuming that the set of terminals to which each physical PICO belongs is

Where P (m) may represent the mth physical PICO within each RHUB combining group and kUE may represent the index of the terminal to which the physical PICO belongs.

The above method is illustrated by the following specific examples.

1. And aiming at the uplink scheduling scene.

Fig. 3 is a schematic implementation diagram of the resource allocation method provided in the embodiment of the present application, as shown in fig. 3, when scheduling physical uplink shared channels (PhysicalUplink Shared Channel, PUSCH) for all terminals in the ith slot, the following steps may be performed:

and 300, selecting a first scheduled terminal. Firstly, according to the scheduling priority, selecting the terminal with the highest priority to be scheduled in the ith time slot, and distributing corresponding frequency domain resources according to the service data volume requirement.

Step 301, placing a first scheduled terminal into a scheduled terminal set.

2. And aiming at downlink scheduling scenes.

The uplink RHUB combining further includes a physical uplink control channel (Physical Uplink Control Channel, PUCCH), and for PUCCH format 1, there is a configuration mode of multiplexing transmission of the multi-terminal codebook, and if the number of multiplexed terminals has different physical PICOs belonging to different RHUBs, the base noise rise of the RHUB combining is also brought. Whereas PUCCH format 1 is mainly feedback of acknowledged (ACKnowledgment, ACK) or unacknowledged (Non-ACKnowledgment, NACK) of a physical downlink shared channel (Physical Downlink Shared Channel, PDSCH), it can be solved by coordinated scheduling of multiple PDSCH terminals fed back on one PUCCH format 1 resource. In order to avoid the overlarge number of multiplexing terminals, the number of terminals scheduled by the same time frequency division can be reduced as much as possible in each time slot, and when the PDSCH of the terminals in all time slots fed back by one PUCCH format 1 is scheduled as much as possible, the physical PICO which is combined as much as possible is ensured to be as little as possible, and the strategy is consistent with the PUSCH scheduling strategy.

The scheduling optimization for the PUSCH and the PDSCH can reduce the background noise rise caused by RHIB merging in the receiving process of the PUSCH and the PUCCH feedback information, ensure the receiving performance of the PUSCH or the PUCCH and further improve the capacity of uplink and downlink transmission of a cell by adjusting the terminal set range and the scheduling sequence of scheduling selection on the premise of not influencing the multi-user scheduling service and not wasting scheduling resources.
