The embodiment of the application does not limit the application scene.
The technical scheme of the application is described in detail below by specific examples. The following embodiments may be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments.
In one embodiment, as shown in fig. 2, a beam control method is provided, which is illustrated by taking application of the method to the network device in fig. 1 as an example, and includes:
s102, determining the number of User Equipment (UE) associated with each SSB wave beam in a synchronous signal SSB wave beam set; the number of the UEs is the number of the UEs performing uplink access by using uplink resources indicated in the SSB beam in one statistical period.
The network device may synchronize with the UE by periodically transmitting the SSB beam set. The SSB beam set may include a plurality of SSB beams, and each SSB beam may have a corresponding number for transmitting a different SSB signal. The SSB signals may include a primary synchronization signal (Primary Synchronization Signals, abbreviated PSS), a secondary synchronization signal (Secondary Synchronization Signals, abbreviated SSS), and a physical broadcast channel (Physical Broadcast Channel, abbreviated PBCH) signal. Each SSB signal occupies 4 OFDM symbols in the time domain and 20 RBs, i.e., 240 subcarriers, in the frequency domain.
The radiation angles of the different SSB beams may be different or the same. Overlapping portions may exist for the coverage areas corresponding to SSB beams of different radiation angles. The UE may receive SSB synchronization signals transmitted by the network device within the coverage of one or more of the SSB beams. The UE may select one SSB beam, for example, the SSB beam with the strongest signal, from the detected SSB beams, and perform random access using the uplink resources associated with the SSB beam.
The uplink resource is an uplink physical random access channel (Physical Random Access Channel, abbreviated as PRACH) resource. The PRACH is an access channel when the UE starts to initiate a call, and after receiving a response message of the fast physical access channel (Fast Physical Access Channel, FPACH), the UE sends RRC Connection Request a message on the PRACH channel according to information indicated by the network device, so as to establish RRC connection to access the network device.
Because the uplink resources associated with different SSB beams are different, after the UE initiates random access by adopting the uplink resources associated with the SSB beams, the network device can determine the SSB beam selected by the UE according to the time-frequency position of the uplink resources of the UE initiating random access.
The network device may set a statistics period, which may be used to adjust the direction of the SSB beam by means of sliding window statistics. The statistical period may be one week or one month, and the length of the statistical period is not limited herein. The network device may determine the number of UEs performing uplink access using the uplink resources indicated in the SSB beam in a statistical period, to obtain the number of UEs associated with the SSB beam. That is, in one statistical period, N UEs perform uplink access by using the uplink resource indicated by the SSB beam, and 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, for each SSB beam in the SSB beam set, a number of UEs associated with the SSB beam. Alternatively, each SSB beam may be a partial SSB beam, for example, each SSB beam is an SSB beam located in the middle area of the SSB beam set.
For example, the SSB beam set sent by the network device includes M SSB beams, the network device may determine the number of UEs associated with each SSB beam, that is, the network device may obtain the number of UEs respectively associated with the M SSB beams, and the number of UEs associated with each SSB beam may be denoted as N1, N2, and … … Nm.
S104, determining a first SSB wave beam in an overload state in the SSB wave beam set according to the number of the UE.
Since the uplink resources indicated in the SSB beam are limited, when multiple UEs select the uplink resources to perform uplink access, the uplink resources may be overloaded, so that some UEs fail to access. Thus, the network device may determine whether each SSB beam is in an overloaded state according to the number of UEs.
In one implementation, the network device may rank the SSB beams according to the number of UEs, and determine the first SSB beam in the overload state according to the ranking result. For example, the SSB beams may be arranged in descending order of the number of UEs, and the SSB beam or beams arranged in front may be regarded as the first SSB beam in the overload state.
In another implementation, the network device may count the total number of UEs served over the SSB beam set in the statistics period, and then compare the number of SSB beam-associated UEs with the total number to determine whether the SSB beam is in an overload state. For example, if the ratio of the number of UEs associated with the SSB beam to the total number is greater than a preset threshold, the SSB beam is considered to be in an overload state. The manner of determining the first SSB beam is not limited herein.
The network equipment can screen all first SSB beams meeting overload conditions from the SSB beam set; the first SSB beam in the overload state may also be selected according to a preset number.
S106, enabling a second SSB beam in the SSB beam set to be close to the first SSB beam.
In order to avoid the UE access failure, the network device may perform load balancing processing on the first SSB beam under the condition of determining the first SSB beam in the overload state, and approach the second SSB beam in the SSB beam set to the first SSB beam.
The second SSB beam may be any one or more SSB beams other than the first SSB beam in the SSB beam set sent by the network device, or may be one or more SSB beams selected by the network device based on the load status, and the determination manner of the second SSB beam is not limited herein. The second SSB beam determined by the network device may be the same or different for the different first SSB beams.
After the network device determines the second SSB beam to be adjusted, the radiation angle of the second SSB beam may be adjusted such that the second SSB beam may be close to the first SSB beam, that is, the angle between the first SSB beam and the second SSB beam may be reduced.
Taking the example that the second SSB beam before adjustment is located at one side of the first SSB beam, the second SSB beam after adjustment may be located at one side of the first SSB beam, may be located at the other side of the first SSB beam, or may be overlapped with the first SSB beam.
For the adjustment manner of the second SSB beam, in one implementation manner, the network device may move the radiation angle of the second SSB beam toward a direction close to the second SSB beam according to a preset adjustment angle, for example, an included angle between the second SSB beam and the first SSB beam before adjustment may be θ1, the preset adjustment angle may be θ, and an included angle between the second SSB beam and the second SSB beam after adjustment 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. The preset gradient may be an equal-length gradient or a progressive gradient, which is not limited herein.
When the network device selects the plurality of second SSB beams to adjust, the adjustment angles corresponding to the different second SSB beams may be the same or different. The network device may adjust the plurality of second SSB beams at the same time, or may adjust the plurality of second SSB beams according to a preset adjustment sequence, which is not limited herein.
After the network device approaches the second SSB beam to the first SSB beam, the number of SSB beams which can be detected by the UE in the coverage area of the first SSB beam increases, and the SSB beam with the highest intensity identified by the UE may be converted from the first SSB beam to the second SSB beam, that is, the probability that the UE selects the uplink resource indicated by the second SSB beam to perform uplink access increases, thereby relieving the load of the uplink resource indicated by the first SSB beam and achieving the effect of load balancing.
Further, after the network device adjusts the second SSB beam, the radiation power of the first SSB beam or the second SSB beam may be adjusted, for example, the radiation power of the first SSB beam is reduced, and/or the radiation power of the second SSB beam is increased, so that the probability that the second SSB beam is selected by the UE is further increased, so that the probability that the first SSB beam is selected is reduced, and the load of uplink resources indicated by the first SSB beam is reduced.
According to the beam control method, the network equipment determines the number of User Equipment (UE) associated with each SSB beam in the synchronous signal SSB beam set; determining a first SSB wave beam in an overload state in the SSB wave beam set according to the number of the UE; then, bringing a second SSB beam in the set of SSB beams close to the first SSB beam; the number of the UEs is the number of UEs performing uplink access by using uplink resources indicated in the SSB beam in one statistical period. The network equipment counts the number of the UE associated with the first SSB wave beam, so that the first SSB wave beam in an overload state can be accurately determined; further, the network device approaches the second SSB beam in the SSB beam set to the first SSB beam, so that a plurality of UEs served by the uplink resource indicated by the first SSB beam can perform random access through the uplink resource indicated by the second SSB beam, so that the number of UEs performing random access through the uplink resource indicated by the first SSB beam is reduced, the load of the uplink resource indicated by the first SSB beam is reduced, and the success rate of accessing the UE to the network device is improved.
In one embodiment, when the network device determines, according to the number of UEs associated with the SSB beams, whether the first SSB beam is in an overload state, the number of UEs may be compared with a first preset threshold, and whether the SSB beam is in an overload state is determined according to a comparison result. And if the number of the UE associated with the SSB beam is greater than a first preset threshold, determining that the SSB beam is the first SSB beam in the overload state.
The first preset threshold may be a fixed value, that is, the first preset thresholds corresponding to different SSB beams are the same. Alternatively, the first preset threshold may be determined by the maximum number of UEs that can be served by the uplink resource indicated in the SSB beam, that is, the first preset thresholds corresponding to different SSB beams may be different.
The first preset threshold may be the maximum number of UEs that can be served by the uplink resource indicated in the SSB beam, or may be the product of the maximum number of UEs and a preset ratio; the manner of determining the first preset threshold is not limited herein. Wherein, the preset proportion can be less than 1. For example, the number of UEs of the SSB beam in the current statistical period is X1, the maximum number of UEs that can be served by the uplink resource indicated by the SSB beam is Xmax, the preset ratio may be S, and if X1 is greater than the product of Xmax and S, that is, the ratio of X1 to Xmax is less than S, the SSB beam may be considered to be in an overload state, and may be determined as the first SSB beam.
According to the beam control method, the network equipment can rapidly screen the first SSB beam in the overload state according to the first preset threshold value; further, since the uplink resources indicated by the different SSB beams are different in size, that is, the number of UEs that can be served by the uplink resources indicated by the different SSB beams is different, determining the first preset threshold by the maximum number of UEs that can be served by the uplink resources indicated in the SSB beams can avoid misjudging SSB beams indicating fewer uplink resources as low-load SSB beams, and also avoid misjudging SSB beams indicating more uplink resources as overload SSB beams, thereby improving the accuracy of beam control.
Fig. 3 is a schematic flow chart of a beam control method in an embodiment, which relates to a manner in which the network device determines the second SSB beam, where, based on the foregoing embodiment, as shown in fig. 3, the method further includes:
s202, comparing the number of UE (user Equipment) associated with the SSB beam with a second preset threshold value aiming at other beams except the first SSB beam in the SSB beam set.
Wherein, the other SSB beams may be SSB beams except for the first SSB beam in the overload state in the SSB beam set. For each other beam, the network device may acquire the number of UEs associated with the SSB beam, respectively, and then compare the number of UEs with a second preset threshold value to determine whether the SSB beam is in a low load state. For the same SSB beam, the second preset threshold may be smaller than the first preset threshold.
The second preset threshold may be a fixed value, that is, the second preset thresholds corresponding to different SSB beams are the same. Alternatively, the second preset threshold may be determined by the maximum number of UEs that can be served by the uplink resource indicated in the SSB beam, that is, the second preset thresholds corresponding to different SSB beams may be different. Because the uplink resources indicated by different SSB beams are different in size, the number of UEs that can be served by the uplink resources indicated by different SSB beams is different, and the second preset threshold is determined by the maximum number of UEs that can be served by the uplink resources indicated in the SSB beams, it is possible to avoid misjudging SSB beams indicating fewer uplink resources as low-load SSB beams, and improve the accuracy of beam control.
S204, selecting a second SSB wave beam in the SSB wave beam set according to the comparison result.
The network device may select a second SSB beam from the set of SSB beams based on the comparison. The terminal device may determine SSB beams having the number of UEs smaller than the corresponding second preset threshold as second SSB beams, or may determine other SSB beams having the number of associated UEs smaller than the second preset threshold as candidate SSB beams; determining a second SSB beam among the candidate SSB beams; the manner of selection of the second SSB beam is not limited herein.
When the network device determines the second SSB beam from among the candidate SSB beams, the candidate SSB beam with the smallest number of associated UEs may be determined as the second SSB beam; alternatively, the network device may determine the candidate SSB beam closest to the first SSB beam as the second SSB beam.
According to the beam adjustment method, the network equipment selects the second SSB beam from the SSB beam set according to the number of the UE, so that the second SSB beam is prevented from being in an overload state after being close to the first SSB beam, and the load of each SSB beam is more balanced; further, the network device determines the candidate SSB beam closest to the first SSB beam as the second SSB beam, so that the influence on the UE accessing the second SSB beam can be reduced, and the user experience is improved.
Fig. 4 is a flow chart of a beam control method in an embodiment, which relates to a manner in which the network device adjusts the second SSB beam, and on the basis of the above embodiment, as shown in fig. 4, the step S106 includes:
s302, executing a beam adjustment step; the beam adjustment step includes: deflecting the angle of the second SSB beam toward the first SSB beam deflection tuning gradient; after one adjustment period, determining the number of UEs after the first SSB beam update; the adjustment period is smaller than the statistical period.
When the network device adjusts the second SSB beam according to the preset adjustment gradient, the network device may monitor the adjustment result in the adjustment process, and determine whether the adjustment of the second SSB beam is in place. The network device may preset an adjustment period, and after adjusting the second SSB beam and undergoing an adjustment period, confirm the adjustment state of the second SSB beam. The adjustment period may be less than the statistical period, for example, the statistical period may be 1 month, and the adjustment period may be 1 week.
The network device may perform a beam adjustment step on the second SSB beam. Deflecting the angle of the second SSB beam toward the first SSB beam deflection tuning gradient; after one adjustment period, the number of UEs after the first SSB beam update is determined.
S304, if the updated number of the UE represents that the first SSB wave beam is in the overload state, returning to the step of executing wave beam adjustment until the updated number of the UE represents that the first SSB wave beam is not in the overload state.
The statistical period set by the network device may be T1, the adjustment period may be T2, and after the angle of the second SSB beam is adjusted by a gradient at the time T, the number of UEs served by the first SSB beam within a time period T1 before the time t+t2 is counted. If the first SSB wave beam is still in the overload state according to the updated UE quantity at the time of T+T2, the second SSB wave beam needs to be continuously adjusted; if it is determined at time t+t2 that the first SSB beam is not in the overload state according to the updated UE number, the second SSB beam does not need to be continuously adjusted.
According to the beam control method, the network equipment monitors the adjustment result of the second SSB beam by setting the adjustment period, so that the second SSB beam can be adjusted to realize that the first SSB beam is converted into a non-overload state from the overload state, UE served by the first SSB beam can be smoothly accessed into the network equipment, and the reliability of beam adjustment is improved.
In one embodiment, a beam steering method is provided, as shown in fig. 5, including:
s401, determining the number of User Equipment (UE) associated with each SSB wave beam in the synchronous signal SSB wave beam set.
S402, determining whether the number of UE (user equipment) associated with the SSB wave beams is larger than a first preset threshold value; if yes, executing S403; if not, the process is ended.
S403, determining whether the number of UE (user Equipment) associated with the SSB beam is smaller than a second preset threshold value for other beams except the first SSB beam in the SSB beam set; if yes, executing S404; if not, the process is ended.
