Description

Technical Field

[0001] The present application relates to the field of communication technology, and in particular to a resource allocation method, apparatus, network equipment and computer-readable storage medium. Background Art

[0002] In the 5G system, due to the difference in frame structure configuration between different cells indoors or outdoors, cross-time slot interference is likely to occur, which in turn leads to a decline in user experience. For example, in scenarios with large uplink business demands such as smart factories and entertainment venues, the demand for video backhaul services is large, so more uplink time slots are configured in the frame structure. In general outdoor scenarios with large downlink business demands, more downlink time slots are configured in the frame structure. Cross-time slot interference will occur in the boundary areas between different scenarios.

[0003] At present, in order to avoid cross-time slot interference, two solutions are usually adopted: the first solution is the time slot closing method, which adopts the time slot blocking for the time slot that will cause cross-time slot interference, and the PRB resources on the time slot will not be used, so as to avoid the cross-time slot interference in the time slot; the second solution is the static resource coordination method, which statically plans the available PRB resources on the cross-time slot to avoid cross-time slot interference. However, although these two solutions are relatively easy to implement, they cannot be adjusted for different existing network services, which easily causes unnecessary waste of air interface resources. Summary of the invention

[0004] The embodiments of the present application provide a resource allocation method, apparatus, network device and computer-readable storage medium, which can solve the problem of air interface resource waste when avoiding cross-time slot interference in related technologies. The technical solution is as follows:

[0005] According to one aspect of an embodiment of the present application, a resource allocation method is performed by a network device deployed in a first cell, the method comprising: receiving an indication message, the indication message being used to indicate a second traffic volume of a second cell in a cross-time slot in a current cycle; in response to the indication message, determining a first available physical resource block (PRB) resource amount of the first cell in a cross-time slot in a cycle subsequent to the current cycle, and a second available PRB resource amount of the second cell in a cross-time slot in a cycle subsequent to the current cycle; and performing cross-time slot resource allocation according to the first available PRB resource amount and the second available PRB resource amount.

[0006] According to one aspect of the embodiments of the present application, a resource allocation method is executed by a network device deployed in a second cell. The method includes: determining the second traffic volume of the second cell in the cross-slot in the current period; sending an indication message carrying the second traffic volume, so that the first cell, in response to the indication message, determines the first available physical resource block (PRB) resource volume of the first cell in the cross-slot in the next period of the current period, and the second available PRB resource volume of the second cell in the cross-slot in the next period of the current period, and performs resource allocation for the cross-slot.

The memory is used to store a computer program. The transceiver is used to transmit and receive data under the control of the processor. The processor is used to read the computer program in the memory and execute the following steps: receiving an indication message for indicating the second traffic volume of the second cell in the cross-slot in the current period; in response to the indication message, determining the first available PRB resource volume of the first cell in the cross-slot in the next period of the current period, and the second available PRB resource volume of the second cell in the cross-slot in the next period of the current period; and performing resource allocation for the cross-slot according to the first available PRB resource volume and the second available PRB resource volume.

[0008] According to one aspect of the embodiments of the present application, a network device is deployed in a second cell and includes: a memory, a transceiver, and a processor. The memory is used to store a computer program. The transceiver is used to transmit and receive data under the control of the processor. The processor is used to read the computer program in the memory and execute the following steps: determining the second traffic volume of the second cell in the cross-slot in the current period; sending an indication message carrying the second traffic volume, so that the first cell, in response to the indication message, determines the first available PRB resource volume of the first cell in the cross-slot in the next period of the current period, and the second available PRB resource volume of the second cell in the cross-slot in the next period of the current period, and performs resource allocation for the cross-slot.

[0009] According to one aspect of the embodiments of the present application, a resource allocation device is applied to a network device deployed in a first cell. The device includes: a message receiving module for receiving an indication message for indicating the second traffic volume of the second cell in the cross-slot in the current period; a message response module for, in response to the indication message, determining the first available PRB resource volume of the first cell in the cross-slot in the next period of the current period, and the second available PRB resource volume of the second cell in the cross-slot in the next period of the current period; and a resource allocation module for performing resource allocation for the cross-slot according to the first available PRB resource volume and the second available PRB resource volume.

[0012] The beneficial effects brought by the technical solution provided by the present application are as follows:

[0013] In the above technical solution, an indication message for indicating the second traffic volume of the second cell in the cross-slot in the current period is received. By responding to the indication message, the first available PRB resource volume of the first cell in the cross-slot in the next period of the current period and the second available PRB resource volume of the second cell in the cross-slot in the next period of the current period are determined, so as to perform resource allocation according to the first available PRB resource volume and the second available PRB resource volume. That is to say, by transmitting an indication message between the first cell and the second cell and using the second traffic volume carried by the indication message for resource allocation, on the basis of accurately avoiding or reducing cross-slot interference, the radio interface resources are utilized to the greatest extent, thereby solving the problem of waste of radio interface resources in avoiding cross-slot interference in the related art.

[0044] KPI, the full English name is Key Performance Indicator, and the Chinese meaning is key performance indicator.

[0045] As mentioned above, in the 5G system, due to the differences in frame structure configurations between indoor and outdoor or different outdoor cells, cross-slot interference is likely to occur, which in turn leads to a decline in user experience.

[0046] It should be understood that the uplink and downlink requirements of the 5G system vary in different scenarios. For example, in scenarios with high uplink service requirements such as smart factories and entertainment venues, the video backhaul service demand is relatively large, and more uplink time slots are configured in the frame structure. Figure 1 An exemplary 2.5ms dual-cycle frame structure applicable to this scenario is shown. In Figure 1 , within a 5ms cycle, there are 2 different types of 2.5ms cycles. The first 2.5ms cycle is DDDSU, and the second 2.5ms cycle is DDSUU (D represents a downlink time slot, U represents an uplink time slot, and S represents a special time slot). Together, it is DDDSUDDSUU. It can be seen that in this 2.5ms dual-cycle frame structure, two consecutive uplink time slots are configured, which means that more distant random access requests can be received, facilitating the improvement of uplink coverage.

[0047] In general outdoor scenarios with high downlink service requirements, more downlink time slots are configured in the frame structure. Figure 2 An exemplary 2.5ms single-cycle frame structure applicable to this scenario is shown. In Figure 2 , within a 5ms cycle, there is only 1 type of 2.5ms cycle, namely DDDSU, and together it is DDDSUDDDSU. It can be seen that in this 2.5ms single-cycle frame structure, more downlink time slots are configured, which is beneficial to increasing the downlink throughput.

[0048] Therefore, for the boundary regions between different scenarios, cross-slot interference will occur, which will have an adverse impact on the user experience.

[0049] For example, as Figure 3 shown, assume that cell 1 adopts the Figure 3 2.5 ms double-cycle frame structure shown, and cell 2 adopts the Figure 3 2.5 ms single-cycle frame structure shown.

[0050] Then, in the boundary region between cell 1 and cell 2, cross-slot interference will be caused due to the different uplink and downlink configurations of some time slots in the frame structure. The interference direction is as shown by the arrow in Figure 3 , that is to say, cell 1 is the interfering cell and cell 2 is the interfered cell.

[0051] Due to the generation of cross-slot interference, the following problems may occur in the boundary region between cell 1 and cell 2:

[0052] 1) If the terminal moves to the edge of the interfered cell, it may not be able to perform random access normally;

[0053] 2) The uplink service rate and downlink service rate of the interfered cell will be affected to a great extent and will decrease significantly;

[0054] 3) Affect the KPI indicators of the interfered cell.

[0055] Therefore, usually the following two solutions are adopted to avoid cross-slot interference:

[0056] The first solution is the time slot closing method, that is, the interfering cell locks the time slots that will cause cross-slot interference to avoid the cross-slot interference of these time slots on the interfered cell; or, the interfered cell locks the time slots that will cause cross-slot interference to avoid the impact of the cross-slot interference on the interfered cell itself. Due to the time slot locking, the PRB resources on this time slot will not be available, resulting in a large waste of radio resources.

[0057] The second solution is the static resource coordination method, that is, the interfering cell and the interfered cell statically plan the range of PRB resources that can be used by each other on the cross-slot to avoid cross-slot interference. Since the available PRB resources are affected by static planning, it is not convenient to adjust for different existing network services. For example, when the traffic volume of the interfering cell is large, it may not be able to use the PRB resources planned for the interfered cell, which will also cause a waste of radio resources.

[0058] As can be seen from the above, there are still defects in the related technologies in avoiding cross-slot interference, such as low utilization rate of radio resources.

[0059] In view of this, the resource allocation method, device, network device, and storage medium provided in this application aim to solve the above technical problems in the related art.

[0060] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are only some of the embodiments of this application, not all of them. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of this application without creative efforts belong to the scope of protection of this application.

[0061] Figure 4 It is a schematic diagram of the implementation environment involved in a resource allocation method. The implementation environment includes a wireless communication system 100, which can be a global system of mobile communication (GSM) system, code division multiple access (CDMA) system, wideband code division multiple access (WCDMA) system, general packet radio service (GPRS) system, long term evolution (LTE) system, LTE frequency division duplex (FDD) system, LTE time division duplex (TDD) system, long term evolution advanced (LTE-A) system, universal mobile telecommunication system (UMTS), worldwide interoperability for microwave access (WiMAX) system, or can also be a 5G new radio (NR) system, etc., which is not limited herein.

[0062] The wireless communication system 100 includes a terminal and a network device. The network device may include a base station 130 and may also include a core network part, such as an evolved packet system (EPS), etc.

[0063] Specifically, a terminal, abbreviated as UE (User Equipment), is also considered a user device or terminal device, which refers to an electronic device that provides voice and / or data connectivity to users, a handheld device with wireless connection capabilities, or other processing devices connected to a wireless modem, etc. For example, the terminal can be a mobile terminal device. For example, a mobile phone (or called a "cellular" phone), and it can also be a computer with a mobile terminal device, such as a portable, pocket-sized, handheld, computer-integrated, or in-vehicle mobile device. In different systems, the name of this terminal may also be different, and it can be a Personal Communication Service (PCS) phone, a cordless phone, a Session Initiated Protocol (SIP) phone, a Wireless Local Loop (WLL) station, a Personal Digital Assistant (PDA), and other devices. This terminal can also be called a system, a subscriber unit, a subscriber station, a mobile station, a mobile, a remote station, an access point, a remote terminal device, an access terminal device, a user terminal device, a user agent, a user device, which is not limited here.

[0064] The base station 130, as an access network device, can be referred to as an access point according to different specific application scenarios, or can be an electronic device in the access network that communicates with terminals through one or more sectors on the air interface, or other names. The base station 130 can be used to mutually replace the received air frames and Internet Protocol (IP) packets, and act as a router between the terminal and the rest of the access network. The rest of the access network can include an IP network. The base station 130 can also coordinate the attribute management of the air interface. For example, the base station 130 can be a Base Transceiver Station (BTS) in a Global System for Mobile communications (GSM) or Code Division Multiple Access (CDMA), or a Node B in a Wide-band Code Division Multiple Access (WCDMA), or an evolved Node B (eNB or e-NodeB) in a Long Term Evolution (LTE) system, or a 5G base station (gNB) in a 5G network architecture (next generation system), or a Home evolved Node B (HeNB), a relay node, a femto, a pico, etc. This is not limited herein.

[0065] Please refer to Figure 5 , an embodiment of the present application provides a resource allocation method, and the method may include the following steps:

[0066] Step 31, determine the second traffic volume of the second cell in the cross-slot in the current period.

[0067] First, it should be noted that the first cell can be a disturbing cell or a disturbed cell. Correspondingly, the second cell can be a disturbed cell or a disturbing cell. Considering that the disturbing cell is for downlink scheduling and the scheduling flexibility is slightly stronger than that of the uplink, for the convenience of description, in the following, the first cell is taken as the disturbing cell and the second cell is taken as the disturbed cell to illustrate the following method embodiments. It should be added here that based on the first cell being the disturbed cell and the second cell being the disturbing cell, the resource allocation process is basically the same, and this is not a specific limitation here.

[0068] Secondly, the second traffic volume, relative to the first traffic volume of the first cell in the cross-slot, in a possible implementation, the first traffic volume is used to indicate the traffic demand of the first cell in the cross-slot; similarly, the second traffic volume is used to indicate the traffic demand of the second cell in the cross-slot.

[0069] In a possible implementation, the second traffic volume can be expressed as the ratio of the number of PRB resources that the second cell needs to occupy in the cross-slot to the total number of PRB resources; in a possible implementation, the second traffic volume can be expressed as the number of PRB resources that the second cell needs to occupy in the cross-slot. It should be noted here that the total number of PRB resources here is configured by the higher layer, and it refers to all the PRB resources that the second cell can use in the cross-slot in the current period.

[0070] Similarly, in a possible implementation, the first traffic volume can be expressed as the ratio of the number of PRB resources that the first cell needs to occupy in the cross-slot to the total number of PRB resources; in a possible implementation, the first traffic volume can be expressed as the number of PRB resources that the first cell needs to occupy in the cross-slot. It should be noted here that the total number of PRB resources here is configured by the higher layer, and it refers to all the PRB resources that the first cell can use in the cross-slot in the current period. It should be noted that, as shown in Figures 1 to 2 shown, the current period can refer to the first 2.5 ms period in the 2.5 ms dual-period frame structure, i.e., DDDSU, or the second 2.5 ms period in the 2.5 ms dual-period frame structure, i.e., DDSUU, or the 2.5 ms period in the 2.5 ms single-period frame structure, i.e., DDDSU. It is not limited here.

[0071] Step 32, send an indication message carrying the second traffic volume.

[0072] That is to say, the indication message is used to indicate the second traffic volume of the second cell in the cross-slot in the current period.

[0073] In a possible implementation, the indication message is encapsulated in a custom interface message negotiated between the terminal and the network device; in a possible implementation, the indication message is encapsulated in an X2 message. For example, the second traffic volume is carried by the ResourceCoordination Information in the X2 message.

[0074] Regarding the sending method of the indication message, in a possible implementation, the indication message is triggered to be sent according to a set period; in a possible implementation, the indication message is triggered to be sent according to a set event. The set event includes but is not limited to the second cell traffic volume change event.

[0075] For example, for the second cell, the traffic volume change = the second traffic volume of the second cell in the cross-slot in the current period - the second available PRB resource amount of the second cell in the cross-slot in the previous period. That is, the traffic volume change is used to indicate the difference in traffic volume between adjacent periods of the second cell in the cross-slot. It should be noted here that the second available PRB resource amount can be expressed as the ratio of the number of PRB resources available for the second cell in the cross-slot to the total number of PRB resources, or it can be expressed as the number of PRB resources available for the second cell in the cross-slot. Which definition method to use depends on the aforementioned definition method of the second traffic volume. For example, if the second traffic volume refers to the ratio of the number of PRB resources that the second cell needs to occupy in the cross-slot to the total number of PRB resources, then the second available PRB resource amount refers to the ratio of the number of PRB resources available for the second cell in the cross-slot to the total number of PRB resources. It should be noted here that the total number of PRB resources here is configured by the upper layer and refers to the total number of PRB resources available for the second cell in the cross-slot in the current period.

[0076] On the one hand, if the traffic volume difference is less than or equal to the set traffic volume, indicating that the traffic volume changes insignificantly and is relatively stable between different periods, there is no need to re-determine the second available PRB resource amount for the next period, so as to avoid excessive message interaction and reduce the burden on the interface between cells. On the other hand, if the traffic volume difference is greater than the set traffic volume, indicating that the traffic volume changes unstably between different periods, it is necessary to re-determine the second available PRB resource amount for the next period. At this time, a second cell traffic volume change event is triggered to send an indication message.

[0077] That is to say, between the first cell and the second cell, indication messages will be periodically transmitted.

[0078] It is worth mentioning that the set period and the set traffic volume can be flexibly adjusted according to the actual needs of the application scenario. For example, the set period is 40 ms, or the set traffic volume is 10%, indicating 10% of the system bandwidth. This is not a specific limitation here. It should be understood that the longer the set period or the larger the set traffic volume, the longer the transmission period of the indication message, so as to avoid excessive message interaction and further avoid excessive frequent changes in the PRB resource amount.

[0079] Thus, the network device deployed in the second cell can transmit the indication message carrying the second traffic volume to the network device deployed in the first cell, so that the network device deployed in the first cell can receive and respond to the indication message to perform resource allocation in the cross-slot.

[0080] It should be noted that before the second cell sends an indication message, the resource allocation of each cell regarding cross-slot is not restricted by this application. After the second cell sends the indication message, each cell executes the resource allocation method of this application for the resource allocation regarding cross-slot.

[0081] Step 33: In response to the indication message, determine the amount of the first available PRB resources of the first cell in the cross-slot in the next cycle of the current cycle, and the amount of the second available PRB resources of the second cell in the cross-slot in the next cycle.

[0082] Similarly to the definition method of the foregoing second available PRB resource amount, in a possible implementation manner, the first available PRB resource amount can be expressed as the ratio of the number of PRB resources that the first cell can use in the cross-slot to the total number of PRB resources; in a possible implementation manner, the first available PRB resource amount can be expressed as the number of PRB resources that the first cell can use in the cross-slot. It should be noted here that the total number of PRB resources here is configured by the higher layer, and refers to the total number of PRB resources that the first cell can use in the cross-slot in the current cycle.

[0083] In a possible implementation manner, as Figure 6 shown, step 33 may include the following steps:

[0084] Step 331: Based on the indication message, determine the second traffic volume of the second cell in the cross-slot in the current cycle, and based on the configuration message related to the first cell, determine the first traffic volume of the first cell in the cross-slot in the current cycle.

[0085] Among them, the configuration message related to the first cell is configured by the higher layer and is used to indicate the configuration of the first cell. For example, the configuration includes but is not limited to: frequency point, random access, downlink channel, and other configurations.

[0086] Step 332: Determine the first available PRB resource amount and the second available PRB resource amount according to the first traffic volume and the second traffic volume.

[0087] As can be seen from the above, as the first traffic volume and / or the second traffic volume changes, the first available PRB resource amount and / or the second available PRB resource amount will also be adjusted accordingly, so that the allocation of the available PRB resources in the cross-slot can be dynamically adjusted based on the traffic demand, thereby avoiding unnecessary waste of radio interface resources while avoiding cross-slot interference.

[0088] Step 34: Perform resource allocation according to the first available PRB resource amount and the second available PRB resource amount.

[0089] Among them, based on the first available PRB resource amount and the second available PRB resource amount, combined with information such as the time slot interference relationship or PCI of the first cell and the second cell, the PRB resource position is determined.

[0090] For example, on the one hand, resource allocation is carried out based on the time division method:

[0091] Without distinguishing between the interfering cell and the interfered cell, allocate according to the number of cross time slots. Assuming there are 3 cross time slots, if the ratio between the first available PRB resource amount and the second available PRB resource amount is 2:1, then, in one possible implementation, please refer back to Figure 3 As shown, the PRB resources available for the first 2 cross time slots (for example, the uplink time slots pointed by the first 2 arrows) are used by the first cell, and the PRB resources available for the last 1 cross time slot (for example, the uplink time slot with the 3rd arrow pointing away) are used by the second cell.

[0092] On the other hand, resource allocation is carried out based on the frequency division method:

[0093] Figures 7a to 7d An exemplary schematic diagram of the PRB resource position structure available for cross time slots is shown. Now, in combination with Figures 7a to 7d , assuming that the ratio between the first available PRB resource amount and the second available PRB resource amount is 2:1, and the PRB resources available for cross time slots include 9 PRBs, the following exemplary description is given for the determination process of the PRB resource position:

[0094] In one possible implementation, distinguish between the interfering cell and the interfered cell. As Figure 7a shown, allocate the PRB resources available for the cross time slots of the interfering cell from back to front. Correspondingly, allocate the PRB resources available for the cross time slots of the interfered cell from front to back.

[0095] In one possible implementation, allocate resources according to PCI%3 of the interfering cell:

[0096] As Figure 7b shown, if PCI%3 of the interfering cell = 0, then allocate the PRB resources available for the cross time slots of the interfering cell from front to back. Correspondingly, allocate the PRB resources available for the cross time slots of the interfered cell from back to front;

[0097] As Figure 7c shown, if PCI%3 of the interfering cell = 1, then allocate the PRB resources available for the cross time slots of the interfering cell from the 2 / 3 position from back to front. Correspondingly, allocate the PRB resources available for the cross time slots of the interfered cell from the 2 / 3 position from front to back;

[0098] As Figure 7dAs shown in the figure, if the PCI of the interfering cell %3 = 2, the available PRB resources in the cross-slot of the interfering cell are allocated from the 1 / 3 position forward, and correspondingly, the available PRB resources in the cross-slot of the interfered cell are allocated from the 1 / 3 position backward.

[0099] Thus, it can be ensured that the interfering cell and the interfered cell are not interfered when allocating the available PRB resources in the cross-slot.

[0100] Through the above process, by transmitting an indication message between the first cell and the second cell and using the second traffic carried by the indication message for resource allocation, on the basis of accurately avoiding or reducing cross-slot interference, the radio interface resources are utilized to the greatest extent. This not only ensures that the uplink and downlink rates of the entire network are minimized in terms of loss, but also effectively improves the uplink and downlink perception of users.

[0101] Please refer to Figure 8 , the embodiment of the present application provides a resource allocation method, which may include the following steps:

[0102] Step 41, determine the second traffic of the second cell in the cross-slot in the current period.

[0103] Among them, the second traffic can be expressed as the ratio of the number of PRB resources that the second cell needs to occupy in the cross-slot to the total number of PRB resources, or can also be expressed as the number of PRB resources that the second cell needs to occupy in the cross-slot.

[0104] Step 42, send an indication message carrying the second traffic.

[0105] Step 43, obtain the first traffic of the first cell in the cross-slot in the current period, and determine the second traffic based on the indication message.

[0106] Among them, the first traffic can be expressed as the ratio of the number of PRB resources that the first cell needs to occupy in the cross-slot to the total number of PRB resources, or can also be expressed as the number of PRB resources that the first cell needs to occupy in the cross-slot.

[0107] Step 44, determine the total traffic in the cross-slot in the current period according to the first traffic and the second traffic.

[0108] Among them, the total traffic volume = the first traffic volume + the second traffic volume, which is used to represent the total traffic demand of the first cell and the second cell in the cross-slot of the current period. Similarly to the aforementioned definition method of the first traffic volume / second traffic volume, the total traffic volume can be expressed as the ratio of the sum of the number of PRB resources that the first cell and the second cell need to occupy in the cross-slot of the current period to the total number of PRB resources, or can also be expressed as the sum of the number of PRB resources that the first cell and the second cell need to occupy in the cross-slot of the current period. It is worth mentioning that the total number of PRB resources here refers to the sum of all PRB resources available to the first cell and the second cell in the cross-slot of the current period.

[0109] Here, the inventor realizes that the sum of the number of PRB resources available to the first cell and the second cell in the cross-slot of the current period is limited, which can also be understood as that the total available PRB resources in the cross-slot have an upper limit. If the total traffic volume is greater than the total available PRB resources, it means that the traffic of the first cell and the second cell in the cross-slot of the current period is saturated. If resource allocation is performed based on the first traffic volume and the second traffic volume, it will cause a certain loss to the system throughput. Therefore, in this embodiment, before resource allocation, it is first necessary to determine whether the total traffic volume is greater than the total available PRB resources, that is, step 45 is executed.

[0110] Among them, the total available PRB resources can be expressed as the sum of the number of PRB resources available to the first cell and the second cell in the cross-slot of the current period, or can also be expressed as the ratio of the sum of the number of PRB resources available to the first cell and the second cell in the cross-slot of the current period to the total number of PRB resources. It should be noted here that the total number of PRB resources refers to the sum of all PRB resources available to the first cell and the second cell in the cross-slot of the current period.

[0111] This total available PRB resources can be flexibly adjusted according to the actual needs of the application scenario, and no specific limitation is constituted here. Taking the definition method of expressing the total available PRB resources as a ratio as an example, when the total available PRB resources are 100%, it means that the sum of the number of PRB resources available to the first cell and the second cell in the cross-slot of the current period accounts for 100% of the total number of PRB resources; or when the total available PRB resources are 90%, it means that the sum of the number of PRB resources available to the first cell and the second cell in the cross-slot of the current period accounts for 90% of the total number of PRB resources.

[0112] Step 45, determine whether the total traffic volume is greater than the total available PRB resources in the cross-slot.

[0113] On the one hand, if the total traffic volume is less than or equal to the total available PRB resources, it means that the traffic in the cross-slot of the first cell and the second cell in the current period is not saturated. Then, the available PRB resources in the cross-slot are sufficient to meet the total traffic demand of the first cell and the second cell in the cross-slot in the current period, and step 46 is executed.

[0114] On the other hand, if the total traffic volume is greater than the total available PRB resources, it means that the traffic in the cross-slot of the first cell and the second cell in the current period is saturated. Then, the available PRB resources in the cross-slot will not be able to meet the total traffic demand of the first cell and the second cell in the cross-slot in the current period, and step 47 is executed to minimize the loss caused to the system throughput.

[0115] Step 46: Determine the first available PRB resource amount and the second available PRB resource amount according to the first traffic volume and the second traffic volume.

[0116] In a possible implementation manner, determine the first available PRB resource amount according to the first traffic volume and the minimum PRB resource amount threshold, and determine the second available PRB resource amount according to the second traffic volume.

[0117] Among them, the minimum PRB resource amount threshold is related to the minimum traffic demand, and can be expressed as the number of PRB resources occupied by the minimum traffic demand, or can also be expressed as the proportion of the number of PRB words occupied by the minimum traffic demand in the total number of all PRB resources.

[0118] This minimum PRB resource amount threshold can be flexibly adjusted according to the actual needs of the application scenario and is not limited here. Taking the definition method of expressing the minimum PRB resource amount threshold as a proportion as an example, assume that the minimum system bandwidth minbr = 3M and the spectral efficiency MCS = 15. Correspondingly, the number of PRB resources occupied by the minimum traffic demand is 3 to 4 PRB resources. At this time, the minimum PRB resource amount threshold = 3 to 4 PRB resources / the total number of all PRB resources.

[0119] Here, the total number of all PRB resources refers to the total number of all available PRB resources of the first cell in the cross-slot in the current period.

[0120] Step 47: Determine the first available PRB resource amount and the second available PRB resource amount according to the set allocation rule.

[0121] In a possible implementation manner, the set allocation rule includes at least one of the following: proportional allocation rule, priority allocation rule.

[0122] Among them, the proportional allocation rule means determining the demand ratio based on the first traffic volume and the second traffic volume, and determining the first available PRB resource amount and the second available PRB resource amount according to the demand ratio.

[0123] The priority-based allocation rule means determining whether the first cell is preferentially allocated based on the allocation priority, and determining the first available PRB resource amount and the second available PRB resource amount.

[0124] Optionally, in a possible implementation, based on the set allocation rule, considering whether the terminal is a user with good signal quality, combining the system resources and the PRB resources available in the cross-slot, determining the first available PRB resource amount and the second available PRB resource amount.

[0125] Step 48: Perform resource allocation according to the first available PRB resource amount and the second available PRB resource amount.

[0126] Through the above process, when the total traffic volume changes following the first traffic volume and / or the second traffic volume, the first available PRB resource amount and / or the second available PRB resource amount will also be adjusted accordingly based on different strategies, so that the allocation of the available PRB resources in the cross-slot can be dynamically adjusted based on the traffic demand, thereby achieving the avoidance of unnecessary waste of radio resources while avoiding cross-slot interference.

[0127] Based on the above definition methods of representing various resource amounts and various traffic volumes as ratios, the following describes the resource allocation method for the cross-slot in each embodiment of the present application:

[0128] As described above, on the one hand, if the total traffic volume is less than or equal to the total available PRB resources, it means that the traffic of the first cell and the second cell in the cross-slot in the current period is not saturated. Then, the first available PRB resources and the second available PRB resources can be determined according to the first traffic volume and the second traffic volume.

[0129] The following provides a detailed description of the resource allocation in this case:

[0130] Please refer to Figure 9 , an embodiment of the present application provides a resource allocation method, which may include the following steps:

[0131] Step 51: Determine the second traffic volume of the second cell in the cross-slot in the current period.

[0132] Step 52: Send an indication message carrying the second traffic volume.

[0133] Step 53: Obtain the first traffic volume of the first cell in the cross-slot in the current period, and determine the second traffic volume based on the indication message.

[0134] Step 54: Determine the first available PRB resource amount according to the first traffic volume and the minimum PRB resource amount threshold.

[0135] Specifically: The first Resource n = Max(Thres Minimum Guarantee, the first ServiceRe n ).

[0136] Among them, the first Resource n represents the first available PRB resource amount, the first ServiceRe n represents the first traffic volume, Thres Minimum Guarantee represents the minimum PRB resource amount threshold, and among them, Max represents the maximum value operation.

[0137] That is to say, when the first ServiceRe n is greater than Thres Minimum Guarantee, take the first ServiceRe n as the first Resource n .

[0138] When the first ServiceRe n is not greater than the minimum PRB resource amount threshold, take Thres Minimum Guarantee as the first Resource n .

[0139] Step 55: Determine the second available PRB resource amount according to the second traffic volume.

[0140] Specifically: The second Resource n = the second ServiceRe n .

[0141] Among them, the second Resource n represents the second available PRB resource amount, and the second ServiceRe n represents the second traffic volume.

[0142] Step 56: Perform resource allocation according to the first available PRB resource amount and the second available PRB resource amount.

[0143] Through the above process, resource allocation in the case of unsaturated services is achieved, and unnecessary waste of air interface resources is avoided on the basis of avoiding cross-slot interference.

[0144] As mentioned above, on the other hand, if the total traffic volume is greater than the total available PRB resource amount, it means that the services of the first cell and the second cell in the cross-slot in the current period are saturated, then the first available PRB resource and the second available PRB resource can be determined according to the set allocation rules.

[0145] Among them, the set allocation rules include but are not limited to: proportional allocation rule, priority allocation rule.

[0146] Now, the resource allocation in the case of the proportional allocation rule is described in detail as follows:

[0147] Please refer to Figure 10 , this application embodiment provides a resource allocation method, which may include the following steps:

[0148] Step 61, determine the second traffic volume of the second cell in the cross-slot of the current period.

[0149] Step 62, send an indication message carrying the second traffic volume.

[0150] Step 63, obtain the first traffic volume of the first cell in the cross-slot of the current period, and determine the second traffic volume based on the indication message.

[0151] Step 64, determine the demand ratio according to the first traffic volume and the second traffic volume.

[0152] Specifically: Ratio = 1 / (the first ServiceRe n + the second ServiceRe n ).

[0153] Among them, the total traffic volume = the first ServiceRe n + the second ServiceRe n ;

[0154] Ratio represents the demand ratio, the first ServiceRe n represents the first traffic volume, and the second ServiceRe n represents the second traffic volume.

[0155] Step 65, determine the first available PRB resource amount according to the first traffic volume, the demand ratio, and the minimum PRB resource amount threshold.

[0156] Specifically, perform a multiplication operation on the first traffic volume and the demand ratio to obtain the first demand amount, and determine the first available PRB resource amount based on the relationship between the first demand amount and the minimum PRB resource amount threshold.

[0157] The calculation formula is: the first Resource n = Max(Thres minimum guarantee, the first demand amount).

[0158] Among them, the first demand amount = Ratio × the first ServiceRe n ;

[0159] The first Resourcen Indicates the first available PRB resource amount, the first ServiceRe n Indicates the first traffic volume, Thres minimum guarantee represents the minimum PRB resource amount threshold, Ratio represents the demand ratio, and Max represents the maximum value operation.

[0160] That is to say, if the first demand amount is greater than Thres minimum guarantee, then use the first demand amount as the first Resource n .

[0161] If the first demand amount is not greater than Thres minimum guarantee, then use Thres minimum guarantee as the first Resource n .

[0162] Step 66, determine the second available PRB resource amount according to the second traffic volume, the total available PRB resource amount, and the first available PRB resource amount.

[0163] Specifically, determine the difference between the total available PRB resource amount and the first available PRB resource amount as the second demand amount, and determine the second available PRB resource amount based on the relationship between the second demand amount and the second traffic volume.

[0164] The calculation formula is: the second Resource n = Min(second ServiceRe n , the second demand amount).

[0165] Wherein, the second demand amount = 100% - the first Resource n ;

[0166] The second Resource n Indicates the second available PRB resource amount, the second ServiceRe n Indicates the second traffic volume, the first Resource n Indicates the first available PRB resource amount, the total available PRB resource amount is 100%, indicating that the sum of the PRB resource quantities that the first cell and the second cell can use in the cross-slot in the current period accounts for 100% of all PRB resource quantities, and all PRB resource quantities refer to the sum of all PRB resource quantities that the first cell and the second cell can use in the cross-slot in the current period, and Min represents the minimum value operation.

[0167] That is to say, if the second demand amount is less than the second ServiceRe n , then use the second demand amount as the second Resource n ;

[0168] If the second demand amount is not less than the second ServiceRen , then the second ServiceRe n As the second Resource n .

[0169] Step 67: Perform resource allocation according to the first available PRB resource amount and the second available PRB resource amount.

[0170] Through the above process, resource allocation according to the proportional allocation rule is realized under the situation of service saturation, unnecessary waste of air interface resources is avoided on the basis of avoiding cross-time slot interference, and the loss of system throughput caused by service saturation is minimized.

[0171] The resource allocation under the priority allocation rule is now described in detail as follows:

[0172] See also Figure 11 , an embodiment of the present application provides a resource allocation method, which may include the following steps:

[0173] Step 71, determining the second traffic volume of the second cell in the cross time slot in the current cycle.

[0174] Step 72: Send an indication message carrying the second service volume.

[0175] Step 73: Obtain the first traffic volume of the first cell in the cross time slot in the current period, and determine the second traffic volume based on the indication message.

[0176] Step 74, determine the allocation priority.

[0177] The allocation priority is used to indicate whether the first cell is allocated first.

[0178] In a possible implementation, the allocation priority is preconfigured, and the allocation priority includes the priority of the first cell and the priority of the second cell. If the priority of the first cell is not lower than the priority of the second cell, the allocation priority indicates that the first cell is allocated first; conversely, if the priority of the first cell is lower than the priority of the second cell, the allocation priority indicates that the second cell is allocated first.

[0179] In a possible implementation, the allocation priority is related to the first traffic volume and the second traffic volume. If the first traffic volume is not less than the second traffic volume, the allocation priority indicates that the first cell is allocated first. On the contrary, if the second traffic volume is greater than the first traffic volume, the allocation priority indicates that the second cell is allocated first.

[0180] It should be noted here that the first cell is preferentially allocated, which can also be understood as the first cell being a high-priority cell and the second cell being a low-priority cell; conversely, the second cell is preferentially allocated, which can also be understood as the second cell being a high-priority cell and the first cell being a low-priority cell.

[0181] Step 75, if the allocation priority indicates that the first cell is preferentially allocated, then determine the first available PRB resource amount according to the first traffic volume, the minimum PRB resource amount threshold, and the total available PRB resource amount.

[0182] Specifically, determine the difference between the total available PRB resource amount and the minimum PRB resource amount threshold as the available PRB resource amount threshold, and determine the first available PRB resource amount based on the relationship between the available PRB resource amount threshold and the first traffic volume.

[0183] The calculation formula is: First Resource n = Min(total available PRB resource amount - Thres minimum guarantee, First ServiceRe n ).

[0184] Among them, the available PRB resource amount threshold = total available PRB resource amount - Thres minimum guarantee;

[0185] First Resource n represents the first available PRB resource amount, First ServiceRe n represents the first traffic volume, Thres minimum guarantee represents the minimum PRB resource amount threshold, the total available PRB resource amount is 100%, which means the sum of the PRB resource amounts that the first cell and the second cell can use in the cross-slot in the current period accounts for 100% of the total PRB resource amount, and the total PRB resource amount refers to the sum of all the PRB resource amounts that the first cell and the second cell can use in the cross-slot in the current period, and Min represents the minimum value operation.

[0186] That is to say, if the available PRB resource amount threshold is less than First ServiceRe n , then use the available PRB resource amount threshold as First Resource n ;

[0187] If the available PRB resource amount threshold is not less than First ServiceRe n , then use First ServiceRe n as First Resource n .

[0188] Step 76, determine the second available PRB resource amount according to the total available PRB resource amount and the first available PRB resource amount.

[0189] Specifically: The second Resource n = Total available PRB resources - The first Resource n .

[0190] Among them, the second Resource n represents the second available PRB resource amount, and the first Resource n represents the first available PRB resource amount. The total available PRB resources is 100%, indicating that the sum of the PRB resources that can be used by the first cell and the second cell in the cross-slot in the current period accounts for 100% of all PRB resources. All PRB resources refer to the sum of all PRB resources that can be used by the first cell and the second cell in the cross-slot in the current period.

[0191] That is to say, on the one hand, based on the first cell priority allocation, the PRB resources that can be used in the cross-slot are preferentially allocated to the first cell according to the first traffic volume. After the allocation of the first cell is completed, the remaining PRB resources among the PRB resources that can be used in the cross-slot can be allocated to the second cell.

[0192] On the other hand, during the priority allocation process, the resource allocation is combined with the minimum PRB resource amount threshold (i.e., Thres minimum guarantee). At the same time, it also ensures that the second cell with a lower priority can at least obtain the resources required by the minimum service demand, which is further beneficial to reducing the loss caused to the system throughput in the case of traffic saturation.

[0193] Similarly, if the allocation priority indicates that the second cell is preferentially allocated, the determination process of the PRB resource amount is basically the same as the above process, and is described as follows:

[0194] Step 77, if the allocation priority indicates that the second cell is preferentially allocated, then based on the relationship between the available PRB resource amount threshold and the second traffic volume, determine the second available PRB resource amount.

[0195] Specifically, if the available PRB resource amount threshold is less than the second traffic volume, then use the available PRB resource amount threshold as the second available PRB resource amount.

[0196] If the available PRB resource amount threshold is not less than the second traffic volume, then use the second traffic volume as the second available PRB resource amount.

[0197] The calculation formula is: The second Resource n = Min(Total available PRB resources - Thres minimum guarantee, Second ServiceRe n ).

[0198] Among them, the available PRB resource amount threshold = the total available PRB resource amount - Thres minimum guarantee;

[0199] Second Resource n represents the second available PRB resource amount, and the second ServiceRe n represents the second traffic volume. Thres minimum guarantee represents the minimum PRB resource amount threshold. The total available PRB resource amount is 100%, which means the sum of the PRB resource amounts that the first cell and the second cell can use in the cross-slot in the current period accounts for 100% of the total PRB resource amount. Min is the minimum value operation. The total PRB resource amount refers to the sum of all the PRB resource amounts that the first cell and the second cell can use in the cross-slot in the current period. Min represents the minimum value operation.

[0200] Step 78: Determine the difference between the total available PRB resource amount and the second available PRB resource amount as the first available PRB resource amount.

[0201] The calculation formula is: First Resource n = the total available PRB resource amount - Second Resource n .

[0202] Among them, First Resource n represents the first available PRB resource amount, and Second Resource n represents the second available PRB resource amount. The total available PRB resource amount is 100%, which means the sum of the PRB resource amounts that the first cell and the second cell can use in the cross-slot in the current period accounts for 100% of the total PRB resource amount. The total PRB resource amount refers to the sum of all the PRB resource amounts that the first cell and the second cell can use in the cross-slot in the current period.

[0203] Step 79: Perform resource allocation according to the first available PRB resource amount and the second available PRB resource amount.

[0204] Through the above process, resource allocation according to the priority allocation rule in the case of traffic saturation is realized, unnecessary waste of air interface resources is avoided on the basis of avoiding cross-slot interference, and at the same time, the loss caused to the system throughput in the case of traffic saturation is minimized as much as possible.

[0205] Furthermore, as mentioned above, when the total traffic volume is greater than the total available PRB resource amount, on the basis of setting the allocation rule, for whether the terminal is a user with good signal quality, the first available PRB resource amount and the second available PRB resource amount can be determined by combining the system resources and the PRB resources available in the cross-slot.

[0206] That is to say, if the terminal is a user with good signal quality, in addition to using the PRB resources available in the cross-slot, it can also use system resources; conversely, if the terminal is a user with poor signal quality, it can only use the PRB resources available in the cross-slot.

[0207] Now, in combination with the proportional allocation rule, the resource allocation in this case is described in detail as follows:

[0208] Please refer to Figure 12 , the embodiment of the present application provides a resource allocation method, which may include the following steps:

[0209] Step 81, determine the second traffic volume of the second cell in the cross-slot in the current period.

[0210] Step 82, send an indication message carrying the second traffic volume.

[0211] Step 83, obtain the first traffic volume of the first cell in the cross-slot in the current period, and determine the second traffic volume based on the indication message.

[0212] Step 84, determine whether the terminal is a user with good signal quality based on the measurement report sent by the terminal resident in the first cell.

[0213] Among them, for the terminal resident in the first cell, the first cell is regarded as the serving cell of this terminal.

[0214] Whether the terminal is a user with good signal quality depends on the signal quality of the serving cell where the terminal resides. Regarding the determination method of the signal quality of the serving cell where the terminal resides, it can be any of the following methods:

[0215] In a possible implementation manner, the signal quality of the serving cell is determined by the A2 measurement report.

[0216] Specifically, for the network device deployed in the first cell, it instructs the terminal resident in the first cell (i.e., the serving cell) to perform A2 measurement. If the terminal measures that the signal quality of the serving cell is lower than the threshold, it sends an A2 measurement report to the network device. Correspondingly, the network device can determine the signal quality of the serving cell based on the received A2 measurement report.

[0217] Thus, when receiving the A2 measurement report sent by the terminal, indicating that the signal quality of the serving cell is lower than the threshold, it can be determined that the terminal is a user with poor signal quality. Conversely, if the A2 measurement report is not received within the first specified period, indicating that the signal quality of the serving cell is higher than the threshold, it is determined that the terminal is a user with good signal quality.

[0218] In a possible implementation manner, the signal quality of the inter-frequency neighboring cell relative to the serving cell is determined by the A3 measurement report.

[0219] Specifically, for a network device deployed in the first cell, it instructs a terminal camping on the first cell (i.e., the serving cell) to perform A3 measurement. If the terminal measures that the signal quality of an inter-frequency neighboring cell exceeds a threshold relative to the serving cell, it sends an A3 measurement report to the network device. Correspondingly, the network device can determine the signal quality of the inter-frequency neighboring cell relative to the serving cell based on the received A3 measurement report.

[0220] Thus, when receiving the A3 measurement report sent by the terminal, indicating that the signal quality of the inter-frequency neighboring cell exceeds the threshold relative to the serving cell, it can be determined that the terminal is a user with poor signal quality. On the contrary, if the A3 measurement report is not received within the second specified period, indicating that the signal quality of the inter-frequency neighboring cell does not exceed the threshold relative to the serving cell, it is determined that the terminal is a user with good signal quality.

[0221] Among them, the threshold of signal quality includes but is not limited to any one of the following: RSRP (Reference Signal Receiving Power) threshold, RSRQ (Reference Signal Receiving Quality) threshold, RSSI (Received Signal Strength Indicator) threshold, and SINR (Signal to Interference plus Noise Ratio) threshold.

[0222] Step 85: If the terminal is a user with good signal quality, determine the first available PRB resource amount according to the first traffic volume and the allocated system resource amount.

[0223] Specifically: The first Resource n = The first ServiceRe n - The allocated system resource amount.

[0224] Among them, the first Resource n represents the first available PRB resource amount, and the first ServiceRe n represents the first traffic volume.

[0225] The allocated system resource amount, expressed as the proportion of the system resources available for the cross-slot allocated by the network device to the terminal in the current cycle to all system resources, is used to indicate the amount of system resources available for the cross-slot allocated by the network device to the terminal in the current cycle. It should be noted here that all system resources herein refer to all system resources allocated by the network device to the terminal in the current cycle, including but not limited to all PRB resource amounts available for the cross-slot allocated by the network device to the terminal.

[0226] Of course, in other embodiments, the allocated system resource amount can also be expressed as the amount of system resources available for the cross-slot allocated by the network device to the terminal in the current cycle, and this embodiment does not constitute a specific limitation.

[0227] Step 86: Determine the second available PRB resource amount according to the total available PRB resource amount and the first available PRB resource amount.

[0228] Specifically: Second Resource n = Total available PRB resource amount - First Resource n .

[0229] Among them, Second Resource n represents the second available PRB resource amount, First Resource n represents the first available PRB resource amount, the total available PRB resource amount is 100%, which represents that the sum of the PRB resource amounts available for the cross-slot of the first cell and the second cell in the current cycle accounts for 100% of all PRB resource amounts, and all PRB resource amounts refer to the sum of all PRB resource amounts available for the cross-slot of the first cell and the second cell in the current cycle.

[0230] Step 87: If the terminal is a user with poor signal quality, determine the demand ratio according to the first traffic volume and the second traffic volume, and determine the first available PRB resource amount according to the first traffic volume, the demand ratio, and the minimum PRB resource amount threshold.

[0231] First, determine the demand ratio according to the first traffic volume and the second traffic volume:

[0232] The calculation formula is: Ratio = 1 / (First ServiceRe n + Second ServiceRe n ).

[0233] Among them, the total traffic volume = First ServiceRe n + Second ServiceRe n ;

[0234] Ratio represents the demand ratio, and the first ServiceRe n represents the first traffic volume, and the second ServiceRe n represents the second traffic volume.

[0235] Secondly, according to the first traffic volume, the demand ratio, and the minimum PRB resource volume threshold, determine the first available PRB resource volume:

[0236] Specifically, perform a multiplication operation on the first traffic volume and the demand ratio to obtain the third demand volume, and determine the first available PRB resource volume based on the relationship between the third demand volume and the minimum PRB resource volume threshold.

[0237] The calculation formula is: the first Resource n = Max(Thres minimum guarantee, Ratio × the first ServiceRe n ).

[0238] Among them, the third demand volume = Ratio × the first ServiceRe n ;

[0239] The first Resource n represents the first available PRB resource volume, the first ServiceRe n represents the first traffic volume, Thres minimum guarantee represents the minimum PRB resource volume threshold, Ratio represents the demand ratio, and Max represents the maximum value operation.

[0240] That is to say, if the third demand volume is greater than Thres minimum guarantee, then use the third demand volume as the first Resource n .

[0241] If the third demand volume is not greater than Thres minimum guarantee, then use Thres minimum guarantee as the first Resource n .

[0242] Step 88, according to the second traffic volume, the total available PRB resource volume, and the first available PRB resource volume, determine the second available PRB resource volume.

[0243] Specifically, determine the difference between the total available PRB resource volume and the first available PRB resource volume as the fourth demand volume, and determine the second available PRB resource volume based on the relationship between the fourth demand volume and the second traffic volume.

[0244] The calculation formula is: the second Resource n = Min(the second ServiceRe n , the fourth demand volume).

[0245] Among them, the fourth demand = 100% - the first Resource n ;

[0246] The second Resource n represents the second available PRB resource amount, and the second ServiceRe n represents the second traffic volume, and the first Resource n represents the first available PRB resource amount. The total available PRB resource amount is 100%, which means that the sum of the PRB resource quantities that the first cell and the second cell can use in the cross-slot in the current period accounts for 100% of all PRB resource quantities. Min represents the minimum value operation. The total number of all PRB resources refers to the sum of all PRB resource quantities that the first cell and the second cell can use in the cross-slot in the current period. Min represents the minimum value operation.

[0247] That is to say, if the fourth demand is less than the second ServiceRe n , then the fourth demand is taken as the second Resource n ;

[0248] If the fourth demand is not less than the second ServiceRe n , then the second ServiceRe n is taken as the second Resource n .

[0249] That is to say, if the terminal can be regarded as a user with good signal quality, for example, a cell center user relatively close to the base station, then this user with good signal quality can preferentially use the system resources other than the PRB resources available in the cross-slot, and then use the PRB resources available in the cross-slot, and will not cause obvious interference to the users of the different-frequency neighboring cells; on the contrary, if it is a user with poor signal quality, for example, a cell edge user relatively far from the base station, or a user in a severely interfered area of the cell, then it can only use the PRB resources available in the cross-slot.

[0250] It should be added that the system resources, compared with the PRB resources available in the cross-slot, belong to non-clean resources, that is, they may generate cross-slot interference with relatively low impact. Although there may be cross-slot interference with relatively low impact, when a user with good signal quality uses this system resource, it will not cause obvious interference to the users of the different-frequency neighboring cells. In other words, when a user with good signal quality uses this system resource, the cross-slot interference generated to the users of the different-frequency neighboring cells can be ignored, so as to effectively reduce the loss caused to the system throughput in the case of traffic saturation.

[0251] Step 89: Perform resource allocation according to the first available PRB resource amount and the second available PRB resource amount.

[0252] Through the above process, resource allocation according to the signal quality distribution rule in the case of service saturation is achieved, unnecessary waste of radio resources is avoided on the basis of avoiding cross-slot interference, and at the same time, the loss caused to the system throughput in the case of service saturation is minimized as much as possible.
