[0004] The SSB (Synchronization Signal and PBCH block) consists of PSS (Primary Synchronization Signals), SSS (Secondary Synchronization Signals), and PBCH (physical broadcast channel), and is associated with multiple applications such as cell search, mobility measurement, and beam management.

[0005] Currently, due to the need for low-altitude network coverage, base station equipment for ground coverage needs to also consider low-altitude coverage, that is, to configure both air-to-air and ground-to-air SSB beams under the same carrier cell. However, since the low-altitude and ground-to-air SSB beams use the same frequency, if signal leakage from neighboring cells occurs, it will introduce mutual interference between the ground and the air, resulting in a poor signal-to-noise ratio of the SSB beams, low low-altitude coverage, and limitations on the configuration of air-to-air SSB beams.

[0051] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0052] This application provides a beam configuration method that can be applied to the application environment shown in Figure 1. The air-to-ground coverage base station can transmit SSB beams both air-to-air and air-to-ground. The air-to-air SSB beam covers at least one air-to-ground physical cell, and the air-to-ground SSB beam covers at least one ground-to-ground physical cell. By configuring the SSB beams transmitted by the air-to-ground coverage base station through the base station network management system, different frequencies are used for the SSB beams corresponding to the air-to-air physical cells and the ground-to-ground physical cells, thereby avoiding mutual interference between air and ground and enhancing the coverage capability of the SSB beams.

[0053] In one embodiment, as shown in Figure 2, a beam configuration method is provided, including the following steps:

[0054] S201, deploy at least two physical cells within the single carrier bandwidth of the base station, and configure SSBs at different frequency domain locations for the different deployed physical cells.

[0055] The at least two physical cells include an air-to-air physical cell and a ground-to-ground physical cell. An air-to-air physical cell refers to a physical cell covered by the SSB beam in the air, and a ground-to-ground physical cell refers to a physical cell covered by the SSB beam in the ground. Deploying at least two physical cells within the single carrier bandwidth of the base station can refer to newly configuring at least two physical cells within the single carrier bandwidth of the base station, or it can refer to reconfiguring at least two already configured physical cells.

[0056] Specifically, for the same set of base station physical equipment, multiple overlapping physical cells are deployed within a single carrier bandwidth through the base station network management system, and the frequency domain positions of the SSBs of the multiple overlapping physical cells are staggered so that the frequency domain positions of the SSBs of the multiple overlapping physical cells do not overlap, thereby forming inter-frequency neighbor cell relationships between the multiple overlapping physical cells.

[0057] For example, within the single carrier bandwidth of a base station, one air-to-ground physical cell and one ground-to-ground physical cell are deployed, with the air-to-ground physical cell configured with a higher frequency domain SSB and the ground-to-ground physical cell configured with a lower frequency domain SSB.

[0058] S202, based on the needs of the business scenario, configure the SSB beams of each physical cell.

[0059] Business scenario requirements can include both air coverage requirements and ground coverage requirements. For example, air coverage requirements refer to the need for specific flight paths or coverage areas of drones, while ground coverage requirements refer to the needs in scenarios where there are building obstructions or open spaces.

[0060] Given that the SSBs of each physical cell are configured in different frequency domain locations, the SSB beam configuration of each physical cell is unified based on the service scenario requirements of each physical cell.

[0061] For example, based on the service scenario requirements of each physical cell, the number and direction of the SSB beams transmitted by the base station to each physical cell are configured, as well as the broadcast control channel for transmitting the SSB beams is configured.

[0062] In the above embodiment, at least two physical cells are deployed within the single carrier bandwidth of the base station, and synchronization signal blocks (SSBs) with different frequency domain locations are configured for the different deployed physical cells. The at least two physical cells include an air-to-ground physical cell and a ground-to-ground physical cell. SSB beam configuration is performed on the SSBs of each physical cell according to service scenario requirements. This embodiment avoids mutual interference between wireless signals from different physical cells by configuring the frequency domain locations of the SSBs of different physical cells, thereby improving the signal-to-noise ratio of the configured SSB beams and enhancing the coverage capability of the air-to-ground physical cell's SSB beams, thus comprehensively improving the quality of the air-to-ground network.

[0063] Based on the above embodiments, in one embodiment, as shown in FIG3, S201 may include:

[0064] S301 configures different physical cell identifiers for different physical cells within the single carrier bandwidth of the base station, and configures the same center frequency and bandwidth for different physical cells.

[0065] The Physical Cell Identifier (PCI) is used to distinguish radio signals from different physical cells. Generally, physical cells within a certain range have different PCIs to avoid PCI conflicts. The center frequency is the ARFCN (Absolute Radio-Frequency Channel Number), a numbering scheme used to identify specific radio frequency channels. ARFCN is typically used to represent the center frequency of a physical cell. The carrier bandwidth is used to represent the carrier bandwidth.

[0066] For the same set of base station physical equipment, when configuring different physical cells through the base station network management system, different physical cell identifiers are configured for different physical cells. The frequency domain bandwidths of these physical cells completely overlap, so the same center frequency and bandwidth are configured for different physical cells.

[0067] S302 configures different global synchronization channel numbers for different physical cells, so as to assign SSBs at different frequency domain locations to different physical cells.

[0068] Different global synchronization channel numbers correspond to different frequency domain locations. The global synchronization channel number is called GSCN (Global Synchronization Channel Number). Each frequency domain location corresponds to a unique global synchronization channel number. By configuring different global synchronization channel numbers for different physical cells, it is possible to configure SSBs for different frequency domain locations for different physical cells.

[0069] It should be noted that this embodiment does not limit the specific frequency domain location of the configured SSB.

[0070] In this embodiment, by configuring the physical cell identifier, center frequency, and bandwidth of the physical cell, the physical cell within a single carrier bandwidth can be deployed. Furthermore, by configuring the global synchronization channel number of the physical cell, the frequency domain position of the SSB of the physical cell can be configured, thus forming inter-frequency neighbor cell relationships between different physical cells.

[0071] Based on the above embodiments, in one embodiment, as shown in FIG4, S202 may include:

[0072] S401, based on the requirements of the business scenario, select the corresponding target SSB beam configuration strategy from the candidate SSB beam configuration strategies.

[0073] The candidate SSB beam configuration strategy is a pre-defined SSB beam configuration strategy for configuring SSB beams of multiple physical cells. The SSB beam configuration strategy includes the method of configuring the time and frequency domain of the SSB beams and the method of configuring the number of SSB beams.

[0074] To meet the needs of different business scenarios, a more suitable SSB beam configuration strategy can be selected from the candidate SSB beam configuration strategies and used as the target SSB beam configuration strategy.

[0075] Optionally, as shown in Figure 5, taking one air-to-ground physical cell and one ground-to-ground physical cell as examples, the existing SSB beam configuration methods are provided, as well as the SSB beam configuration methods under three candidate SSB beam configuration strategies in this embodiment. That is, the candidate SSB beam configuration strategies include at least a first SSB beam configuration strategy, a second SSB beam configuration strategy, and a third SSB beam configuration strategy. In this application, the SSB beam configured for the air-to-ground physical cell is referred to as the air-to-ground SSB beam, and the SSB beam configured for the ground-to-ground physical cell is referred to as the ground-to-ground SSB beam.

[0076] Scenario 1: In the existing technology, three SSB beams are configured for air and four SSB beams are configured for ground. In this case, the air-to-ground physical cell and the ground-to-ground physical cell are actually the same physical cell. The air-to-ground SSB beams and the ground-to-ground SSB beams have the same frequency domain position within the single carrier bandwidth, so they will interfere with each other in the event of signal leakage.

[0077] Scenario 2: The first SSB beam configuration strategy is used to indicate the transmission of SSB beams from different physical cells within the same time slot, while maintaining the same number of SSB beams for each physical cell. Therefore, under this strategy, the air-to-ground and ground-to-ground SSB beams are still jointly configured, and the SSB beams of the air-to-ground and ground-to-ground physical cells are tightly coupled. Compared to existing technologies, the number of air-to-ground SSB beams remains unchanged, but the frequencies of the three SSB beams in the air-to-ground physical cell are different from the frequencies of the four SSB beams in the ground-to-ground physical cell. This significantly reduces the probability of mutual interference between the air-to-ground and ground-to-ground SSB beams, improving the signal-to-noise ratio and coverage of the air-to-ground SSB beams.

[0078] Scenario 3: The second SSB beam configuration strategy is used to instruct the transmission of SSB beams from different physical cells within the same time slot, and increases the number of SSB beams for each physical cell to the target number. Therefore, under the second SSB beam configuration strategy, the air-to-ground SSB beams and ground-to-ground SSB beams are configured independently, and the SSB beams for air-to-ground and ground-to-ground physical cells are decoupled. Compared to existing technologies, increasing the number of air-to-ground SSB beams to the target number is sufficient to configure spatial vertical multi-layer SSB beams, such as a vertical 4+3 beam or a horizontal 7 beam. Simultaneously, the frequencies of the air-to-ground physical cell's SSB beams and the ground-to-ground physical cell's SSB beams are different frequencies, significantly reducing the probability of mutual interference between air-to-ground and ground-to-ground SSB beams, thus improving the signal-to-noise ratio and coverage of the air-to-ground SSB beams. It should be noted that the second SSB beam configuration strategy further improves the coverage of the air-to-ground SSB beams compared to the first SSB beam configuration strategy.

[0079] Scenario 4: The third SSB beam configuration strategy is used to instruct the transmission of SSB beams for different physical cells in different time slots, and increases the number of SSB beams for each physical cell to the target number. Therefore, under the third SSB beam configuration strategy, the air-to-ground SSB beams and ground-to-ground SSB beams are configured independently, and the SSB beams for air-to-ground and ground-to-ground physical cells are decoupled. Compared to existing technologies, increasing the number of air-to-ground SSB beams to the target number is sufficient to configure spatial vertical multi-layer SSB beams, such as a vertical 4+3 beam or a horizontal 7 beam. Simultaneously, the frequencies of the air-to-ground physical cell SSB beams and the ground-to-ground physical cell SSB beams are different frequencies, significantly reducing the probability of mutual interference between air-to-ground and ground-to-ground SSB beams, and improving the signal-to-noise ratio and coverage of the air-to-ground SSB beams. It should be noted that, compared to the second SSB beam configuration strategy, the third SSB beam configuration strategy does not incur SSB beam power loss because it does not require the transmission of multiple SSB beams at the same time.

[0080] Optionally, for the third SSB beam configuration strategy, different SSB-Positions In Burst and SSB-periodicity Serving Cells can be configured for different physical cells to ensure that the SSB beams of different physical cells are not transmitted in the same time slot.

[0081] Understandably, taking 3.5G as an example, adding a set of 20ms period SSBs only increases the overall overhead by about 0.5%, and the resource reduction is controllable and will not seriously affect the available resources of the service channel.

[0082] S402 employs a target SSB beam configuration strategy to configure the SSB beams of each physical cell.

[0083] Based on the overall service scenario requirements of each physical cell, and after determining the target SSB beam configuration strategy, the target SSB beam configuration strategy is adopted to configure the SSB beams transmitted by the base station to each physical cell. In other words, the time-frequency domain of the SSB signal is configured to configure the SSB beams.

[0084] Optionally, the beam direction of the SSB beam corresponding to the SSB of each physical cell is determined; a target SSB beam configuration strategy is adopted, and the SSB beam of each physical cell is configured according to the beam direction of the SSB beam corresponding to the SSB of each physical cell.

[0085] SSB beamforming is commonly used in beam scanning scenarios, where a base station can transmit SSB beams in one direction at a given time and then transmit SSB beams in different directions at multiple times to cover the entire physical cell. This involves configuring the beam direction of the SSB beams for each physical cell, and employing a target SSB beam configuration strategy to configure the number of SSB beams, time-frequency domain, and transmission time slots for each physical cell's SSB beams, thereby achieving SSB beamforming configuration for each physical cell.

[0086] In this embodiment, three different SSB beam configuration strategies are provided. By using any one of these strategies to configure the SSB beams of each physical cell, the signal-to-noise ratio of the configured SSB beams can be improved, as well as the coverage of the airborne SSB beams can be improved, thereby optimizing network quality.

[0087] Based on the above embodiments, in one embodiment, as shown in FIG6, after configuring SSB for a physical cell and before configuring SSB beams for the physical cell's SSB, the above beam configuration method may further include:

[0088] S601 allocates a dedicated Physical Resource Block (PRB) for the broadcast control channel of a physical cell within a single carrier bandwidth.

[0089] The service channel resources used by each physical cell do not overlap. A portion of the PRB resources within the single carrier bandwidth is allocated separately to one of the physical cells. This allows dedicated PRBs to be allocated to the broadcast control channels of each physical cell within the single carrier bandwidth, enabling each physical cell's broadcast control channels to independently use the dedicated PRB resources within the single carrier bandwidth.

[0090] S602, the unallocated PRB is used as a shared PRB, and the shared PRB is allocated to the broadcast control channel of each physical cell.

[0091] Furthermore, the remaining PRB resources within a single carrier bandwidth are treated as shared PRB resources, and the broadcast control channels of each physical cell share the shared PRB resources within the single carrier bandwidth.

[0092] As an optional implementation method in this embodiment, after configuring the SSB beam of the physical cell, the beam configuration method may further include: reallocating the shared PRB to the broadcast control channel of each physical cell according to the service load requirements of each physical cell.

[0093] For example, after services begin operating in each physical cell, the service load requirements of each physical cell are obtained. Then, based on the DSS (Dynamic Spectrum Sharing) function, rate matching is performed on the SSB resource locations of each physical cell. The service load requirements of each physical cell are positively correlated with the number of shared PRBs allocated. The higher the service load requirements of a physical cell, the more shared PRB resources it receives. In other words, more shared PRB resources are reallocated to physical cells with high service load requirements, and fewer shared PRB resources are reallocated to physical cells with low service load requirements. This further improves the rationality of channel resource configuration for each physical cell and optimizes network quality.

[0094] In this embodiment, the channel resources of each physical cell are reasonably configured, and multiple physical cells share the service channel resources within a single carrier bandwidth, while avoiding co-channel interference, which can further improve network quality.

[0095] In one embodiment, an optional example of a beam configuration method is provided, as shown in Figure 7, including the following steps:

[0096] S701 configures different physical cell identifiers for different physical cells within the single carrier bandwidth of the base station, and configures the same center frequency and bandwidth for different physical cells.

[0097] Physical cells include air-to-air physical cells and ground-to-ground physical cells.

[0098] S702 configures different global synchronization channel numbers for different physical cells, so as to assign SSBs at different frequency domain locations to different physical cells.

[0099] Different global synchronization channel numbers correspond to different frequency domain locations.

[0100] S703 allocates a dedicated PRB for the broadcast control channel of a physical cell within a single carrier bandwidth.

[0101] S704 uses unallocated PRBs as shared PRBs and allocates the shared PRBs to the broadcast control channels of each physical cell.

[0102] S705 selects the corresponding target SSB beam configuration strategy from the candidate SSB beam configuration strategies according to the needs of the business scenario.

[0103] The candidate SSB beam configuration strategy includes at least a first SSB beam configuration strategy, a second SSB beam configuration strategy, and a third SSB beam configuration strategy. The first SSB beam configuration strategy is used to indicate the transmission of SSB beams from different physical cells within the same time slot, while keeping the number of SSB beams in each physical cell unchanged. The second SSB beam configuration strategy is used to indicate the transmission of SSB beams from different physical cells within the same time slot, while increasing the number of SSB beams in each physical cell to the target number. The third SSB beam configuration strategy is used to indicate the transmission of SSB beams from different physical cells within different time slots, while increasing the number of SSB beams in each physical cell to the target number.

[0104] S706, determine the beam direction of the SSB beam corresponding to the SSB of each physical cell.

[0105] The S707 employs a target SSB beam configuration strategy, configuring the SSB beams of each physical cell according to the beam direction of the SSB beams corresponding to the SSBs of each physical cell.

[0106] S708 reallocates shared PRBs for the broadcast control channels of each physical cell based on the service load requirements of each physical cell.

[0107] The specific process of the above steps can be found in the description of the above method embodiments. The implementation principle and technical effect are similar, and will not be repeated here.

[0108] It should be understood that although the steps in the flowcharts of the above embodiments are shown sequentially according to the arrows, these steps are not necessarily executed in the order indicated by the arrows. Unless explicitly stated herein, there is no strict order restriction on the execution of these steps, and they can be executed in other orders.

These steps or stages are not necessarily completed at the same time, but can be executed at different times. The execution order of these steps or stages is not necessarily sequential, but can be performed alternately or in turn with other steps or at least some of the steps or stages of other steps.

The solution provided by this apparatus is similar to the implementation described in the above method; therefore, the specific limitations in one or more beam configuration apparatus embodiments provided below can be found in the limitations of the beam configuration method described above, and will not be repeated here.
