To facilitate an understanding of the present application, relevant technical knowledge related to embodiments of the present application will be first introduced herein.

Millimeter waves are introduced into the 5G, and energy focusing is performed on one angle through multiple antennas to form beams. The SSB is a synchronization signal block, and is composed of broadcast information, a primary synchronization signal, and a secondary synchronization signal. Downlink signal synchronization in the 5G is realized by an SSB set, a plurality of SSBs form an SSB set for periodic transmission, and the beam direction of each SSB is different from the associated uplink PRACH resource. Wherein, each SSB has a number for UE identification. When the UE performs downlink synchronization, it first detects and decodes all SSBs, acquires downlink configuration information such as system information, and then selects an uplink PRACH resource carried by the SSB with the strongest detected signal, and performs random access on the uplink PRACH resource. After receiving the random access request, the base station can judge the SSB selected by the UE according to the time-frequency position of the uplink PRACH resource.

In actual network deployment, a situation that a plurality of UEs compete for uplink PRACH resources associated with certain SSBs may occur, resulting in failure of uplink access of the UEs. For example, if people gather in an area in a certain beam direction, the SSB in the beam direction is detected as the strongest signal SSB by multiple UEs, so that the multiple UEs perform random access on the uplink PRACH resource associated with the SSB. Similarly, if some uplink PRACH resources associated with the SSB do not have the UE performing random access at the same time, the uplink PRACH resources associated with the SSB are in a waste state.

In view of the above problems, an embodiment of the present application provides a resource allocation method and related devices, where the number of UEs served by an uplink PRACH resource associated with each SSB in a statistical period is counted on a network device side, a utilization rate of the uplink PRACH resource associated with the SSB in the statistical period is calculated according to the number of UEs served in the statistical period, and if the utilization rate of the uplink PRACH resource associated with the SSB in the statistical period exceeds a threshold, dynamic capacity expansion is performed on the uplink PRACH resource associated with the SSB; the dynamically expanded uplink PRACH resource is scheduled from uplink PRACH resources associated with other SSBs, and an antenna angle difference (i.e., a beam direction of the SSB) when the SSBs are transmitted and an idle uplink PRACH resource in the statistical period need to be considered during scheduling, that is, it is determined which of the other SSBs schedules the uplink PRACH resource to the SSB according to the beam direction and the number of the idle uplink PRACH resources.

The embodiments of the present application will be described in detail below with reference to the accompanying drawings.

The structure of the network device 120 may be the structure of the network device shown in fig. 2.

Referring to fig. 3, fig. 3 is a flowchart illustrating a resource allocation method according to an embodiment of the present disclosure, where the resource allocation method includes the following steps.

S301, determining the number of terminals served by the first physical random access channel resource associated with the first synchronization signal block in a preset time period.

The preset time period may be a sliding period, that is, a period in which the network device issues a synchronization signal block set to the cell; the first synchronization signal block is any one synchronization signal block in the synchronization signal block set; the number of the first physical random access channel resources is at least one; the terminal served by the first physical random access channel resource refers to a terminal which performs random access through the first physical random access channel resource.

S302, adjusting the first physical random access channel resource associated with the first synchronization signal block according to the number of the terminals and/or the beam direction of the first synchronization signal block to obtain a target synchronization signal block.

Each first synchronization signal block corresponds to a beam direction; the adjusting the first physical random access channel resources associated with the first synchronization signal block comprises increasing a number of the first physical random access channel resources associated with the first synchronization signal block and decreasing a number of the first physical random access channel resources associated with the first synchronization signal block.

For example, when there are more terminals served by the first physical random access channel resource associated with the first synchronization signal block, normal access of other terminals may be affected, and the number of the first physical random access channel resource associated with the first synchronization signal block needs to be increased; on the contrary, when there are fewer terminals served by the first physical random access channel resource associated with the first synchronization signal block, the first physical random access channel resource associated with the first synchronization signal block may be idle, and the number of the first physical random access channel resource associated with the first synchronization signal block needs to be reduced to adjust the number of the first physical random access channel resources to other synchronization signal blocks, so as to implement uplink load balancing of the whole cell.

And S303, transmitting the target synchronization signal block to a terminal.

S304, the terminal receives the target synchronization signal block from the network equipment.

It can be understood that the terminal may refer to one terminal, or may refer to multiple terminals, that is, one terminal receives the first synchronization signal block after the associated physical random access channel resource is adjusted, or multiple terminals all receive the first synchronization signal block after the associated physical random access channel resource is adjusted. And after receiving the first synchronization signal block after adjusting the associated physical random access channel resource, the terminal may select the adjusted physical random access channel resource for random access.

It can be seen that, in the embodiment of the present application, the network device first determines the number of terminals served by the first physical random access channel resource associated with the first synchronization signal block in a preset time period, and since the beam direction of each synchronization signal block is determined, the network device also determines the terminal density in the beam direction of the first synchronization signal block; then adjusting the first physical random access channel resources associated with the first synchronization signal block according to the number of the terminals and/or the beam direction of the first synchronization signal block to obtain a target synchronization signal block, namely increasing the number of the first physical random access channel resources associated with the first synchronization signal block when the terminal concentration degree in the beam direction of the first synchronization signal block is high, and decreasing the number of the first physical random access channel resources associated with the first synchronization signal block when the terminal concentration degree in the beam direction of the first synchronization signal block is low; then the target synchronous signal block is sent to a terminal; therefore, the physical random access channel resources associated with the synchronous signal blocks can be dynamically adjusted, so that the quantity of the physical random access channel resources associated with the synchronous signal blocks is matched with the terminal density in the beam direction of the synchronous signal blocks, and the success rate of uplink random access of the terminal is improved.

In some possible examples, before determining the number of terminals served by the first physical random access channel resource associated with the first synchronization signal block within the preset time period, the method further comprises: and sending a synchronous signal block set to a terminal, wherein the synchronous signal block set comprises N synchronous signal blocks, the N synchronous signal blocks comprise the first synchronous signal block, the wave beam direction of each synchronous signal block in the N synchronous signal blocks is different, N is a positive integer, and N is more than or equal to 2.

For example, in one of the sliding periods, the network device issues a synchronization signal block set to the cell, where the synchronization signal block set includes N synchronization signal blocks, where different synchronization signal blocks are sent in different directions, and the N synchronization signal blocks may cover the entire cell, that is, a terminal in any area of the entire cell can receive a synchronization signal block with a strongest signal, and each synchronization signal block is associated with different physical random access channel resources, and the physical random access channel resources may be selected by the terminal for random access.

It can be seen that, in this example, since the number of terminals in different directions has differences, the number of terminals in different physical random access channel resource services also has differences, and the network device may count the number of terminals in the physical random access channel resource service associated with each synchronization signal block, so as to dynamically adjust the number of physical random access channel resources associated with each synchronization signal block in combination with the beam direction of each synchronization signal block, thereby implementing uplink load balancing in the whole cell and providing a random access success rate of the terminal.

In some possible examples, the adjusting the first physical random access channel resource associated with the first synchronization signal block according to the number of terminals and/or the beam direction of the first synchronization signal block includes: determining a first utilization rate of the first physical random access channel resource in a preset time period according to the number of the terminals; and adjusting the first physical random access channel resource associated with the first synchronous signal block according to the first utilization rate and/or the beam direction of the first synchronous signal block.

The utilization rate of the physical random access channel resource associated with the synchronization signal block refers to a ratio of the number of terminals actually accessed to the physical random access channel resource associated with the synchronization signal block in a preset time period to the maximum number of terminals allowed to be accessed to the physical random access channel resource associated with the synchronization signal block.

For example, SSB (i) is associated with 1 PRACH resource, where PRACH1 is the maximum number of PRACH1 allowed access terminals of 100, and PRACH1 actually has access to 50 terminals, then the utilization rate of the SSB (i) associated PRACH resource is 50%. Or, SSB (i) associates 2 PRACH resources, which are PRACH1 and PRACH2, respectively, and the maximum number of PRACH1 and PRACH2 allowed access terminals is 100, then the maximum number of the SSB (i) associated PRACH resources allowed access terminals is 200, whereas PRACH1 actually has access to 50 terminals and PRACH2 actually has access to 70 terminals, then the number of the actually accessed terminals of the SSB (i) associated PRACH resources is 120, so that the utilization rate of the SSB (i) associated PRACH resources is 60%.

It can be seen that, in this example, the network device may calculate the utilization rate of the physical random access channel resources associated with the synchronization signal block by using the number of terminals served by the physical random access channel resources associated with the synchronization signal block, and dynamically adjust the number of the physical random access channel resources associated with each synchronization signal block according to the resource utilization rate and in combination with the beam direction of each synchronization signal block, which is beneficial to intuitively determine whether the physical random access channel resources associated with the synchronization signal block need to be adjusted.

In some possible examples, the adjusting the first physical random access channel resource associated with the first synchronization signal block according to the first utilization and/or the beam direction of the first synchronization signal block includes: judging whether the first utilization rate is greater than a preset threshold value or not; if the first utilization rate is greater than the preset threshold, adjusting a first physical random access channel resource associated with the first synchronization signal block according to the first utilization rate and/or the beam direction of the first synchronization signal block.

For example, the network device calculates the number of UEs served by the uplink PRACH resource associated with each SSB in the delivered SSB set, then determines whether the current utilization rate of the uplink PRACH resource associated with each SSB exceeds a Threshold PRACH _ usage _ Threshold, and expands the uplink PRACH resources associated with the SSBs to increase the number of the uplink PRACH resources if the utilization rate of some uplink PRACH resources associated with the SSBs exceeds the Threshold PRACH _ usage _ Threshold.

It can be understood that the utilization threshold depends on a specific network deployment situation, and the utilization thresholds corresponding to the physical random access channel resources associated with different synchronization signal blocks may be the same or different.

As can be seen, in this example, the network device determines whether to adjust the physical random access channel resource associated with the synchronization signal block according to the comparison result by setting the resource utilization rate threshold value for comparing with the actual resource utilization rate, which is beneficial to quickly and accurately determining whether to adjust the physical random access channel resource associated with the synchronization signal block.

In some possible examples, the adjusting the first physical random access channel resource associated with the first synchronization signal block comprises: determining the physical random access channel resource with the lowest utilization rate in the physical random access channel resources associated with the N synchronous signal blocks, and scheduling the resource from the physical random access channel resource with the lowest utilization rate to the first physical random access channel resource associated with the first synchronous signal block; or determining the synchronous signal block with the largest beam direction difference with the beam direction of the first synchronous signal block in the N synchronous signal blocks, and scheduling resources from the physical random access channel resources associated with the synchronous signal block with the largest beam direction difference with the first synchronous signal block to the first physical random access channel resources associated with the first synchronous signal block.

For example, when the utilization rate of the uplink PRACH resource associated with a certain SSB (i) exceeds a preset threshold, capacity expansion of the uplink PRACH resource associated with the SSB (i) is required, and the sources of these capacity expansion resources may be scheduled from the uplink PRACH resources associated with other SSBs (j), where the uplink PRACH resource associated with the SSB (j) has the lowest utilization rate, or the uplink PRACH resource associated with the SSB (i) has the lowest beam direction association (the largest direction angle difference) from the SSBs.

It can be seen that, in this example, when a physical random access channel resource associated with a certain synchronization signal block needs to be scheduled, the scheduled synchronization signal block is a synchronization signal block with the lowest utilization rate of the physical random access channel resource associated in the synchronization signal block set, or the beam direction has the largest difference from the synchronization signal block needing to be scheduled, which is beneficial to implement uplink load balancing of the whole cell and provides a random access success rate of the terminal.

In some possible examples, the adjusting the first physical random access channel resource associated with the first synchronization signal block according to the first utilization and/or the beam direction of the first synchronization signal block includes: determining a second utilization rate of a second physical random access channel resource associated with N-1 synchronous signal blocks in the preset time period to obtain N-1 second utilization rates, wherein the N-1 synchronous signal blocks are synchronous signal blocks except the first synchronous signal block in the N synchronous signal blocks, and the N-1 synchronous signal blocks correspond to the N-1 second utilization rates one to one; screening out the corresponding synchronous signal blocks with the second utilization rate not greater than the preset threshold value from the N-1 synchronous signal blocks to obtain M second synchronous signal blocks, wherein M is a positive integer and is not less than 1 and not more than N-1; and adjusting the first physical random access channel resource associated with the first synchronization signal block according to the first utilization rate, the beam direction of the first synchronization signal block, the second utilization rates corresponding to the M second synchronization signal blocks and the beam directions of the M second synchronization signal blocks.

It can be seen that, in this example, when adjusting the first physical random access channel resource associated with the first synchronization signal block, the beam direction of each synchronization signal block and the corresponding resource utilization rate are fully considered, which is beneficial to improving the rationality of resource scheduling.

In some possible examples, the adjusting the first physical random access channel resource associated with the first synchronization signal block according to the first utilization rate, the beam direction of the first synchronization signal block, the second utilization rates corresponding to the M second synchronization signal blocks, and the beam directions of the M second synchronization signal blocks includes: determining the scheduling priority of each second synchronization signal block according to the first utilization rate, the beam direction of the first synchronization signal block, the second utilization rate corresponding to each second synchronization signal block, and the beam direction of each second synchronization signal block; and adjusting the first physical random access channel resource associated with the first synchronous signal block according to the scheduling priority of each second synchronous signal block.

For example, the SSB set issued by the network device includes SSBs (1), SSBs (2),. ·. And calculating the scheduling priority of the synchronization signal blocks to be SSB (1) < SSB (2) <. < SSB (j), and then selecting the corresponding synchronization signal blocks as the scheduled synchronization signal blocks according to the scheduling priority, for example, scheduling the uplink PRACH resource associated with the SSB (j) with the maximum scheduling priority to the SSB (i).

As can be seen, in this example, the network device may determine, from the synchronization signal blocks with the utilization rate lower than the preset threshold, a scheduling priority of each synchronization signal block with the utilization rate lower than the preset threshold according to the resource utilization rate and the beam direction, and then schedule the physical random access channel resource according to the scheduling priority, which is beneficial to increasing alternatives for resource scheduling.

In some possible examples, the determining the scheduling priority of each of the second synchronization signal blocks according to the first utilization rate, the beam direction of the first synchronization signal block, the second utilization rate corresponding to each of the second synchronization signal blocks, and the beam direction of each of the second synchronization signal blocks includes: determining the number of physical random access channel resources required to be scheduled by the first synchronization signal block according to the first utilization rate, wherein the number of the physical random access channel resources required to be scheduled by the first synchronization signal block refers to the number of the physical random access channel resources required to be scheduled when the first utilization rate is reduced to a preset threshold value; determining the number of idle physical random access channel resources associated with each second synchronization signal block according to a second utilization rate corresponding to each second synchronization signal block, wherein the number of idle physical random access channel resources associated with each second synchronization signal block refers to a difference value between the number of physical random access channel resources when the second utilization rate corresponding to each second synchronization signal block reaches a preset threshold value and the number of physical random access channel resources which are used currently; and determining the scheduling priority of each second synchronous signal block according to the number of physical random access channel resources to be scheduled of the first synchronous signal block, the beam direction of the first synchronous signal block, the number of idle physical random access channel resources associated with each second synchronous signal block and the beam direction of each second synchronous signal block.

For example, SSB (i) associates 1 PRACH resource, where, for PRACH1, the maximum number of allowed access terminals for PRACH1 is 100, the utilization rate of all the SSB associated PRACH resources is preset to 50%, and PRACH1 actually has accessed 90 terminals, and the actual utilization rate of the SSB (i) associated PRACH resource is 90%, and if the actual utilization rate of the SSB (i) associated PRACH resource is reduced to 50%, it is necessary to increase the number of the SSB (i) associated PRACH resource allowed access terminals by at least 180, that is, the increased PRACH resource is at least allowed to access 80 terminals, so that it may be determined that the number of the SSB (i) physical random access channel resources that need to be scheduled is at least 1, which may allow the maximum number of access terminals to be as large as PRACH 1.

If the number of physical random access channel resources to be scheduled by the SSB (i) is to be determined in further detail, the number of idle PRACH resources available for the scheduled SSB may be determined first. Assuming that other SSB (j) resources for scheduling are associated with 3 PRACH resources, which are PRACH2, PRACH3, and PRACH4, respectively, the maximum number of PRACH2 allowed access terminals is 80, and the maximum number of PRACH3 and PRACH4 allowed access terminals is 40, that is, the maximum number of SSB (j) associated PRACH resources is 160; the actual access of the PRACH resources associated with the SSB (j) to 16 terminals, that is, the actual utilization rate of the PRACH resources associated with the SSB (j) is 10%; adopting any one of PRACH2, PRACH3, and PRACH4 to access the 16 terminals does not make the actual utilization rate of the PRACH resources associated with SSB (j) reach 50%, that is, the idle number of the PRACH resources associated with SSB (j) is 2; or, if the actual utilization rate of the PRACH resources associated with the SSB (j) is increased to 50%, at least 64 terminals need to be accessed, and the 64 terminals are allocated to the PRACH2 and the PRACH3, or both the PRACH2 and the PRACH4, that is, the number of idle PRACH resources associated with the SSB (j) is 2. At this time, it can be calculated that the number of physical random access channel resources that SSB (i) needs to schedule may be 1, for example PRACH2; the number of physical random access channel resources that SSB (i) needs to schedule may also be 2, for example PRACH3 and PRACH4.

It can be seen that, in this example, when the scheduling priority is calculated, the number of physical random access channel resources to be scheduled, the beam direction of each synchronization signal block, and the number of idle physical random access channel resources associated with each synchronization signal block are fully considered, which is beneficial to improving the rationality of resource scheduling.

In some possible examples, the determining the scheduling priority of each second synchronization signal block according to the number of physical random access channel resources that the first synchronization signal block needs to schedule, the beam direction of the first synchronization signal block, the number of idle physical random access channel resources associated with each second synchronization signal block, and the beam direction of each second synchronization signal block includes: determining a scheduling priority for each of the second synchronization signal blocks according to the following equation:

wherein, the PRACH _ Schedule _ Priority (j) is a scheduling Priority of the second synchronization signal block; angle (i) is the beam direction of the first synchronization signal block; angle (j) is the beam direction of the second synchronization signal block; the PRACH _ Demand (i) is the number of physical random access channel resources needing to be scheduled by the first synchronous signal block; the PRACH _ unused (j) is the number of idle physical random access channel resources associated with the second synchronization signal block; alpha is a first adjusting coefficient used for adjusting the weight of the beam direction difference; beta is a second adjusting coefficient used for adjusting the weight of the number of the idle physical random access channel resources.

In a specific implementation, the beam directions Angle (i) and Angle (j) of the synchronization signal block may be antenna transmission angles for transmitting SSB (i) and SSB (j); the values of the adjustment coefficients α and β may be set according to the actual network deployment situation.

In some possible examples, the adjusting the first physical random access channel resource associated with the first synchronization signal block according to the scheduling priority of each of the second synchronization signal blocks includes: and scheduling the idle physical random access channel resource associated with the second synchronous signal block with the highest scheduling priority as the first physical random access channel resource associated with the first synchronous signal block.

For example, after the scheduling Priority corresponding to each SSB is calculated, the PRACH resource associated with the SSB (j) with the largest PRACH _ Schedule _ Priority (j) is selected as the scheduled object, and the idle PRACH resource is allocated to the SSB (i), where the allocated resource number is PRACH _ unused (j).

As can be seen, in this example, the idle physical random access channel resource associated with the synchronization signal block with the highest scheduling priority is scheduled as the physical random access channel resource associated with the synchronization signal block that needs capacity expansion, which is beneficial to ensuring the success rate of resource scheduling and the influence on other synchronization signal blocks after resource scheduling.

In some possible examples, the determining the number of terminals served by the first physical random access channel resource associated with the first synchronization signal block within the preset time period includes: receiving random access requests sent by a plurality of terminals according to the synchronous signal block set in a preset time period; determining the corresponding relation between the plurality of terminals and the N synchronous signal blocks according to the time-frequency position of the physical random access channel resource for transmitting the random access requests of the plurality of terminals; and determining the number of terminals served by the first physical random access channel resource associated with the first synchronization signal block in a preset time period according to the corresponding relation between the plurality of terminals and the N synchronization signal blocks.

In the specific implementation, when the UE performs downlink synchronization, it first detects and decodes all SSBs to obtain downlink configuration information such as system information, and then selects an uplink PRACH resource associated with the SSB with the strongest signal, and performs random access on the uplink PRACH resource, and after receiving the random access request, the base station can determine the SSB selected by the UE according to the time-frequency position of the uplink PRACH resource.

In this example, the network device may determine the synchronization signal block selected by the terminal accessing the network according to the time-frequency position of the terminal accessing the physical random access channel resource, so as to accurately count the number of terminals served by the physical random access channel resource associated with each synchronization signal block.

The following is further described with reference to specific examples.

Referring to fig. 4, fig. 4 is a schematic flowchart of another resource allocation method according to an embodiment of the present application, where the resource allocation method includes the following operation steps.

S401, the network equipment sends a synchronization signal block set to the cell.

In a specific implementation, an SSB set may be issued for the base station, where the SSB set includes a plurality of SSBs, each SSB has a corresponding number and is associated with different uplink PRACH resources, and each SSB corresponds to a different beam direction, that is, an antenna transmission angle.

S402, the terminal detects the synchronous signal block set and selects a physical random access channel resource associated with one synchronous signal block in the synchronous signal block set for random access.

In a specific implementation, the UE may detect the SSB set, and select an uplink PRACH resource associated with one of the SSBs for uplink access, where the one of the SSBs may be the one with the strongest signal strength.

S403, the network device counts the number of terminals served by the physical random access channel resource associated with each synchronization signal block in the synchronization signal block set in the sliding period.

In specific implementation, the base station can judge which SSB the UE selects according to the uplink PRACH resource used by the uplink access of the UE; then, the base station counts the number of the UE served by the uplink PRACH resource associated with each SSB in the sliding period T. If the UE does not use the uplink resource (for example, the UE leaves the coverage of the base station, is powered off, and switches to other uplink resources), the number is not counted.

S404, judging whether the utilization rate of the physical random access channel resource associated with each synchronous signal block exceeds a preset threshold value.

S405, if the utilization rate of the physical random access channel resource associated with a certain synchronous signal block exceeds a preset threshold value, the physical random access channel resource associated with the synchronous signal block is increased.

S406, otherwise, not adjusting the physical random access channel resource associated with the synchronization signal block.

It can be seen that, in this example, the network device issues a synchronization signal block set to the cell, each synchronization signal block in the synchronization signal block set is associated with different physical random access channel resources and different beam directions, any terminal may select the physical random access channel resource associated with any synchronization signal block for random access, the network device may count the condition of the physical random access channel resource access terminal associated with any synchronization signal block, determine the utilization rate of the physical random access channel resource associated with any synchronization signal block, and when the utilization rate is greater than a preset threshold, increase the number of the physical random access channel resources associated with the corresponding synchronization signal block, so that the number of the physical random access channel resources associated with the synchronization signal block matches the terminal density degree in the beam direction of the synchronization signal block, thereby increasing the success rate of uplink random access of the terminal in the beam direction.
