The technical solution of the present application will be described in detail below with specific examples. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments.

In one embodiment, as shown in Figure 2, a beam control method is provided. The application of this method to the network device in Figure 1 is used as an example to illustrate, including:

S102. Determine the number of user equipment UEs associated with each SSB beam in the synchronization signal SSB beam set; the number of UEs is the number of UEs that use the uplink resources indicated in the SSB beams for uplink access within a statistical period.

Network equipment can achieve downlink signal synchronization with the UE by periodically sending SSB beam sets. The above SSB beam set may include multiple SSB beams, and each SSB beam may have a corresponding number and be used to send different SSB signals. The above-mentioned SSB signals may include Primary Synchronization Signals (PSS for short), Secondary Synchronization Signals (SSS for short) and Physical Broadcast Channel (PhysicalBroadcast Channel for short) PBCH signals. Each SSB signal occupies 4 OFDM symbols in the time domain and 20 RBs in the frequency domain, that is, 240 subcarriers.

Among them, the radiation angles of different SSB beams can be different or the same. The coverage ranges corresponding to SSB beams with different radiation angles may overlap. The UE can receive the SSB synchronization signal sent by the network device within the coverage of one SSB beam or multiple SSB beams. The UE can select one SSB beam among the multiple detected SSB beams, such as the SSB beam with the strongest signal, and use the uplink resources associated with the SSB beam for random access.

The above-mentioned uplink resources are uplink physical random access channel (Physical Random Access Channel, PRACH for short) resources. PRACH is the access channel when the UE initially initiates a call. After receiving the Fast Physical Access Channel (FPACH) response message, the UE will send an RRC Connection Request message on the PRACH channel according to the information indicated by the network device. Establishment of RRC connection to access network equipment.

Since the uplink resources associated with different SSB beams are different, after the UE uses the uplink resources associated with the SSB beam to initiate random access, the network device can determine the SSB beam selected by the UE based on the time-frequency position of the uplink resource associated with the random access initiated by the UE.

The network device can set a statistical period, and the above statistical period can be used to adjust the direction of the SSB beam through sliding window statistics. The above statistical period can be one week or one month, and the length of the statistical period is not limited here. The network device can determine the number of UEs that use the uplink resources indicated in the SSB beam for uplink access within a statistical period, and obtain the number of UEs associated with the SSB beam. That is to say, within a statistical period, N UEs use the uplink resources indicated by the SSB beam for uplink access, then the number of UEs associated with the SSB beam is N.

Each SSB beam in the SSB beam set may be all beams in the SSB beam set, and the network device may determine the number of associated UEs for each SSB beam in the SSB beam set. Alternatively, the above-mentioned SSB beams may also be partial SSB beams. For example, the above-mentioned SSB beams are SSB beams located in the middle region of the SSB beam set.

For example, the SSB beam set sent by the network device includes M SSB beams. The network device can determine the number of UEs associated with each SSB beam. That is to say, the network device can obtain the number of UEs associated with the M SSB beams. Each SSB beam The number of associated UEs can be expressed as N1, N2,...Nm.

S104. Determine the first SSB beam in the overload state in the SSB beam set according to the number of UEs.

Since the uplink resources indicated in the SSB beam are limited, when multiple UEs select the uplink resources for uplink access, the uplink resource load may be excessive, causing access failure for some UEs. Therefore, the network device can determine whether each SSB beam is in an overloaded state based on the number of UEs.

In one implementation, the network device can sort each SSB beam according to the number of UEs, and determine the first SSB beam in the overload state according to the sorting result. For example, the above-mentioned SSB beams may be arranged in descending order according to the number of UEs, and the top one or more SSB beams may be regarded as the first SSB beam in an overloaded state.

In another implementation, the network device can count the total number of UEs served by the SSB beam set in the statistical period, and then compare the number of UEs associated with the SSB beam with the total number to determine whether the SSB beam is in an excess state. load status. For example, if the ratio of the number of UEs associated with an SSB beam to the total number is greater than a preset threshold, the SSB beam is considered to be in an overloaded state. The method for determining the first SSB beam is not limited here.

The network device can filter out all the first SSB beams that meet the overload condition from the SSB beam set; it can also select the first SSB beams in the overload state according to the preset number.

S106. Move the second SSB beam in the SSB beam set close to the first SSB beam.

In order to avoid UE access failure, when the network device determines that the first SSB beam is in an overloaded state, it can perform load balancing processing on the first SSB beam and move the second SSB beam in the SSB beam set closer to the first SSB beam.

Wherein, the above-mentioned second SSB beam may be any one or more SSB beams except the first SSB beam in the set of SSB beams sent by the network device, or one or more SSB beams selected by the network device based on the load status, The method for determining the second SSB beam is not limited here. For different first SSB beams, the second SSB beams determined by the network device may be the same or different.

After the network device determines the second SSB beam to be adjusted, the radiation angle of the second SSB beam can be adjusted so that the second SSB beam can be close to the first SSB beam, that is, between the first SSB beam and the second SSB beam. angle decreases.

Taking the second SSB beam before adjustment being located on one side of the first SSB beam as an example, the adjusted second SSB beam can be located on one side of the first SSB beam, or on the other side of the first SSB beam, or it can be Coincident with the first SSB beam.

Regarding the adjustment method of the second SSB beam, in one implementation, the network device can move the radiation angle of the second SSB beam in a direction closer to the second SSB beam according to a preset adjustment angle, for example, the second SSB beam before adjustment. The angle between the SSB beam and the first SSB beam may be θ1, the preset adjustment angle may be θ, and the angle between the adjusted second SSB beam and the second SSB beam may be θ1-θ.

In another implementation, the network device may adjust the direction of the second SSB beam according to a preset adjustment gradient so that the second SSB beam is close to the first SSB beam. Wherein, the above-mentioned preset adjustment gradient may be an equal length gradient or a progressive gradient, which is not limited here.

It should be noted that when the network device selects multiple second SSB beams for adjustment, the adjustment angles corresponding to different second SSB beams may be the same or different. The network device may adjust multiple second SSB beams at the same time, or may adjust multiple second SSB beams in a preset adjustment sequence, which is not limited here.

After the network device moves the second SSB beam closer to the first SSB beam, the number of SSB beams that can be detected by the UE within the coverage of the first SSB beam increases, and the SSB beam with the strongest intensity recognized by the UE may be converted from the first SSB beam. The second SSB beam means that the probability that the UE selects the uplink resource indicated by the second SSB beam for uplink access increases, thereby alleviating the load of the uplink resource indicated by the first SSB beam and achieving a load balancing effect.

Further, after the network device adjusts the second SSB beam, it can also adjust the radiation power of the first SSB beam or the second SSB beam, for example, reduce the radiation power of the first SSB beam, and/or increase the radiation power of the second SSB beam. The radiation power further increases the probability that the second SSB beam is selected by the UE, so that the probability of the first SSB beam being selected is reduced, and the load of the uplink resource indicated by the first SSB beam is reduced.

In the above beam control method, the network device determines the number of user equipment UEs associated with each SSB beam in the synchronization signal SSB beam set; determines the first SSB beam in the overload state in the SSB beam set based on the number of UEs; then, The second SSB beam is close to the first SSB beam; where the above number of UEs is the number of UEs that use the uplink resources indicated in the SSB beam for uplink access within a statistical period. Since the network device counts the number of UEs associated with the first SSB beam, the first SSB beam in the overloaded state can be accurately determined; further, the network device moves the second SSB beam in the SSB beam set close to the first SSB beam, so that multiple UEs served by the uplink resources indicated by the first SSB beam can perform random access through the uplink resources indicated by the second SSB beam, such that the number of UEs that perform random access through the uplink resources indicated by the first SSB beam Reduce, reduce the load of the uplink resources indicated by the first SSB beam, and improve the success rate of the UE accessing the network device.

In one embodiment, when the network device determines whether the first SSB beam is in an overloaded state based on the number of UEs associated with the SSB beam, the network device may compare the number of UEs with the first preset threshold, and determine whether the SSB beam is in an overloaded state based on the comparison result. Overload status. If the number of UEs associated with the SSB beam is greater than the first preset threshold, the SSB beam is determined to be the first SSB beam in an overloaded state.

The above-mentioned first preset threshold may be a fixed value, that is to say, the first preset threshold corresponding to different SSB beams is the same. Optionally, the above-mentioned first preset threshold may be determined by the maximum number of UEs that can be served by the uplink resources indicated in the SSB beam. That is to say, the first preset threshold corresponding to different SSB beams may be different.

The above-mentioned first preset threshold may be the maximum number of UEs that can be served by the uplink resource indicated in the SSB beam, or it may be the product of the above-mentioned maximum number of UEs and the preset ratio; the method for determining the first preset threshold is not limited here. . Wherein, the above preset ratio may be less than 1. For example, the number of UEs in the SSB beam in the current statistical period is X1, and the maximum number of UEs that can be served by the uplink resource indicated by the SSB beam is Xmax. The above preset ratio can be S. If That is, if the ratio of X1 to Xmax is less than S, the SSB beam can be considered to be in an overloaded state and can be determined as the first SSB beam.

With the above beam control method, the network device can quickly filter out the first SSB beam in the overloaded state according to the first preset threshold; further, since the sizes of the uplink resources indicated by different SSB beams are different, that is to say, the sizes of the uplink resources indicated by different SSB beams are different. The number of UEs that can be served by uplink resources is different. The first preset threshold is determined by determining the maximum number of UEs that can be served by the uplink resources indicated in the SSB beam, which can avoid misjudgment of SSB beams indicating less uplink resources as low load. SSB beams can also avoid misjudgment of SSB beams indicating more uplink resources as overloaded SSB beams, thereby improving the accuracy of beam control.

Figure 3 is a schematic flow chart of a beam control method in an embodiment. This embodiment relates to a way for a network device to determine a second SSB beam. Based on the above embodiment, as shown in Figure 3, the above method also includes:

S202. For other beams in the SSB beam set except the first SSB beam, compare the number of UEs associated with the SSB beam with the second preset threshold.

Wherein, the other SSB beams mentioned above may be SSB beams in the SSB beam set except the first SSB beam which is in the overload state. For each other beam, the network device can obtain the number of UEs associated with the SSB beam respectively, and then compare the number of UEs with the second preset threshold to determine whether the SSB beam is in a low load state. For the same SSB beam, the above-mentioned second preset threshold may be smaller than the first preset threshold.

The above-mentioned second preset threshold may be a fixed value, that is to say, the second preset threshold corresponding to different SSB beams is the same. Optionally, the above-mentioned second preset threshold may be determined by the maximum number of UEs that can be served by the uplink resources indicated in the SSB beam. That is to say, the second preset threshold corresponding to different SSB beams may be different. Since the sizes of the uplink resources indicated by different SSB beams are different, the number of UEs that can be served by the uplink resources indicated by different SSB beams is different. The second preset threshold is determined by the maximum number of UEs that can be served by the uplink resources indicated by the SSB beams. This can avoid misjudgment of SSB beams indicating less uplink resources as low-load SSB beams and improve the accuracy of beam control.

S204. According to the comparison result, select the second SSB beam from the SSB beam set.

The network device may select the second SSB beam from the SSB beam set based on the above comparison result. The terminal device may determine the SSB beam whose number of UEs is less than the corresponding second preset threshold as the second SSB beam, or may determine other SSB beams whose associated number of UEs is less than the second preset threshold as candidate SSB beams; in The second SSB beam is determined among the candidate SSB beams; the selection method of the second SSB beam is not limited here.

When the network device determines the second SSB beam among the candidate SSB beams, it may determine the candidate SSB beam with the smallest number of associated UEs as the second SSB beam; optionally, the network device may determine the candidate SSB beam that is closest to the first SSB beam. , determined as the second SSB beam.

In the above beam adjustment method, the network device selects the second SSB beam in the SSB beam set according to the number of UEs, which can avoid placing the second SSB beam close to the first SSB beam and causing the second SSB beam to be in an overload state, which will increase the load of each SSB beam. More balanced; further, the network device determines the candidate SSB beam closest to the first SSB beam as the second SSB beam, which can reduce the impact on UEs accessing the second SSB beam and improve user experience.

Figure 4 is a schematic flowchart of a beam control method in an embodiment. This embodiment involves a way for a network device to adjust the second SSB beam. Based on the above embodiment, as shown in Figure 4, the above S106 includes:

S302. Execute the beam adjustment step; the beam adjustment step includes: deflecting the angle of the second SSB beam toward the first SSB beam with a deflection adjustment gradient; determining the number of UEs after the first SSB beam is updated after an adjustment period; the adjustment period is less than the statistical period .

When the network device adjusts the second SSB beam according to the preset adjustment gradient, the network device can monitor the adjustment result during the adjustment process to determine whether the adjustment of the second SSB beam is in place. The network device can preset an adjustment period, and after adjusting the second SSB beam and going through an adjustment period, confirm the adjustment status of the second SSB beam. The above-mentioned adjustment period may be shorter than the statistical period. For example, the statistical period may be one month and the adjustment period may be one week.

The network device may perform beam adjustment steps on the second SSB beam. Deflect the angle of the second SSB beam toward the first SSB beam with a deflection adjustment gradient; after an adjustment period, determine the number of UEs after the first SSB beam is updated.

S304. If the updated number of UEs indicates that the first SSB beam is in an overloaded state, return to the beam adjustment step until the updated number of UEs indicates that the first SSB beam is not in an overloaded state.

The statistical period set by the network device can be T1, and the adjustment period can be T2. After adjusting the angle of the second SSB beam by a gradient at time T, the first SSB beam serves the first SSB beam within the time period T1 before time T at time T+T2. The number of UEs. If the first SSB beam is still in an overloaded state based on the updated number of UEs at time T+T2, the second SSB beam needs to continue to be adjusted; if the first SSB beam is determined based on the updated number of UEs at time T+T2 If the beam is not in an overloaded state, there is no need to continue adjusting the second SSB beam.

In the above beam control method, the network equipment monitors the adjustment result of the second SSB beam by setting the adjustment period, so that the adjustment of the second SSB beam can realize the conversion of the first SSB beam from the overload state to the non-overload state, so that the first SSB UEs served by beams can smoothly access network equipment, which improves the reliability of beam adjustment.

In one embodiment, a beam control method is provided, as shown in Figure 5, including:

S401. Determine the number of user equipments UE associated with each SSB beam in the synchronization signal SSB beam set.
