Technical Field
[0001] This application relates to the field of wireless communication technology, and in particular to a communication method, a first base station, a storage medium, and a computer program product. Background Technology
[0002] To meet the requirements for low-altitude communication coverage, the sidelobes of terrestrial network antennas are often used to cover the low altitude, such as... Figure 1 As shown.
[0003] However, existing terrestrial network stations are spaced close together, and signals travel unobstructed in the air, resulting in significant interference at low altitudes and a low Signal-to-Interference-plus-Noise Ratio (SINR), averaging over 10 dB lower than on the ground. This leads to frequent handover failures, dropped calls, and network disconnections, making it difficult to meet low-altitude service requirements. To reduce interference, a separate network could be built specifically for low-altitude operations, equipped with a Remote Radio Unit (RRU) and other hardware, with the antenna main lobe covering the low-altitude region.

[0044] 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.
[0045] The technical solutions of this application and how they solve the aforementioned technical problems will be described in detail below through embodiments and in conjunction with the accompanying drawings. The embodiments below can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments.
[0046] Furthermore, the technical solutions described in the embodiments of this application can be combined arbitrarily without conflict.
[0047] This application provides a communication method applied to a first base station. The first base station includes an antenna unit connected to an RRU. The antenna unit includes a first antenna whose main lobe covers a first ground area and a second antenna whose main lobe covers a first space area, or a third antenna whose main lobe covers both the first ground area and the first space area.
[0048] In the embodiments of this application, there are multiple first base stations, and the distance between adjacent first base stations meets the set edge rate requirements.
[0049] It should be noted that, in the embodiments of this application, a small number of base stations can be selected from existing ground base stations according to distance, for example, one base station can be selected every 5km. 5km is the distance corresponding to the edge rate reaching 25Mbps for this type of base station. The selected ground base stations can be modified to become the first base station, thereby forming a sparse asymmetric network, such as... Figure 3 As shown. Specific edge rate requirements can be set based on actual needs and application scenarios, and correspondingly, the distance between adjacent first base stations is also determined accordingly, which is not limited in this embodiment. Furthermore, the ground base stations not selected and converted into first base stations are designated as second base stations, used to provide services to different terminals located within the second ground area.
[0050] It should be noted that, in the embodiments of this application, the selected base station is already equipped with an antenna whose main lobe covers the first ground area, i.e., the first antenna. An additional antenna, i.e., the second antenna, is added to cover the first spatial area, such as... Figure 4 As shown, or, replacing its own configured antenna with an independent electrically adjustable antenna that serves as both a main lobe covering the first ground area and the first space area, i.e., a third antenna, such as... Figure 5 As shown, the first base station is thus obtained.
[0051] It should be noted that, in the embodiments of this application, the first ground area, the first space area, and the second ground area can be set according to actual needs and application scenarios, and the embodiments of this application do not impose any limitations. Specifically, the first space area can be a certain low-altitude area.
[0052] Based on the aforementioned first base station, the communication method provided in the embodiments of this application is described in detail below.
[0053] Figure 6 This is a flowchart illustrating a communication method provided in an embodiment of this application. Figure 6 As shown in the embodiments of this application, the communication method applied to the first base station mainly includes the following steps:
[0054] S101. Using antenna elements, a first beam facing the first ground region and a second beam facing the first space region are formed.
[0055] In embodiments of this application, the first base station may utilize antenna elements to form a first beam facing a first ground region and a second beam facing a first space region.
[0056] It should be noted that, in the embodiments of this application, the first beam faces the first ground area, that is, a ground-to-ground beam, and the second beam faces the first space area, that is, an air-to-space beam.
[0057] In embodiments of this application, if the antenna unit includes a first antenna and a second antenna, since the main lobes of the two antennas respectively cover a first ground region and a first spatial region, the first antenna is used to form a first beam, and the second antenna is used to form a second beam. Furthermore, the first antenna is connected to a first channel of the RRU, and the second antenna is connected to a second channel of the RRU. The first channel is one or more channels in the RRU, and the second channel is one or more channels in the RRU. See also... Figure 4 The first channel can be half of the channels in the RRU, and the second channel can be the other half of the channels in the RRU.
[0058] In embodiments of this application, if the antenna element includes a third antenna, and the third antenna includes a first dual-polarized element and a second dual-polarized element; the first dual-polarized element can be one row of dual-polarized elements in the antenna element, and the second dual-polarized element can be another row of dual-polarized elements in the antenna element. In this case, the first dual-polarized element forms a portion of the antenna, its main lobe covering a first ground region. Based on this, the first dual-polarized element is used to form a first beam, and the second dual-polarized element forms another portion of the antenna, its main lobe covering a first spatial region. Based on this, the second dual-polarized element is used to form a second beam. Furthermore, the first dual-polarized element is connected to a first channel of the RRU, and the second dual-polarized element is connected to a second channel of the RRU. Similarly, the first channel can be one or more channels in the RRU, and the second channel can be one or more channels in the RRU. See also... Figure 5 The first channel can be half of the channels in the RRU, and the second channel can be the other half of the channels in the RRU.
[0059] In the embodiments of this application, as described in step S101, the first base station can utilize antenna elements to form a first beam facing a first ground area and a second beam facing a first space area, thus achieving air and ground coverage. If both the first and second base stations use the same frequency, low-altitude signal line-of-sight propagation, and low-altitude drone terminals performing data uploads and other services, will cause significant uplink interference rise to neighboring ground stations, with measured interference rise values reaching 10-15 dB. To reduce the impact of such interference, the first and second base stations should stagger resources as much as possible when scheduling resources for terminals. Specifically, the first base station can also perform the following steps: scheduling first frequency domain resources for one or more terminals accessing the first base station; wherein the first frequency domain resources and the second frequency domain resources are frequency-misaligned, and the second resource is the resource scheduled by the second base station for one or more terminals accessing the second base station. Furthermore, the first frequency domain resources include uplink resources and downlink resources; the uplink and downlink resources are asymmetrical.
[0060] In the embodiments of this application, considering the large number of existing ground terminals, the following resource configuration and scheduling scheme is adopted to minimize the modification requirements of the ground network. Taking a Frequency Division Duplexing (FDD) system with a carrier bandwidth of 30MHz as an example, see [link to relevant documentation]. Figure 7 It mainly involves:
[0061] 1. When the second base station schedules frequency domain resources for the accessing terminals, both uplink and downlink scheduling begin from the leftmost position. The starting point for uplink scheduling is limited to 20MHz to the left, and for downlink scheduling, it is limited to 10MHz to the left. The bandwidth and scheduling starting position specified above are only examples and can be adjusted according to factors such as the ratio of uplink to downlink traffic in the air and on the ground.
[0062] 2. When the first base station schedules frequency domain resources for the access terminal, it can use the full bandwidth to reduce the impact on the terrestrial network; both uplink and downlink scheduling start from the rightmost position to ensure that the beams are staggered as much as possible.
[0063] In the embodiments of this application, the first spatial region can be a low-altitude region. Due to the line-of-sight propagation of low-altitude signals, when only the sidelobes of the ground network cover the low altitude, the low-altitude signals are chaotic and disordered, resulting in significant interference and low SINR. The average SINR is more than 10 dB lower than that of the ground, causing frequent network disconnections and dropped calls for terminals. To reduce interference from the low-altitude Synchronization Signal Block (SSB), a specific SSB configuration scheme can be adopted for the first base station. This will be described in detail below.
[0064] In the embodiments of this application, the first cell of the first base station is configured with a first beam and a second beam. The first base station may also perform the following steps: transmitting the first SSB of the first cell through the first beam and transmitting the second SSB of the first cell through the second beam at the same frequency but different time domains.
[0065] It should be noted that, in the embodiments of this application, see... Figure 4 For a scheme where the main lobe of the first antenna covers the first ground area and the main lobe of the second antenna covers the first spatial area, taking a 4-channel RRU as an example, two channels of the RRU are connected to the first antenna, and the other two channels are connected to the second antenna. The first base station is configured with two SSBs, a first SSB and a second SSB. The first SSB and the second SSB use the same frequency but are time-domain staggered. The first SSB is transmitted through the first beam formed by the first antenna, and the second SSB is transmitted through the second beam formed by the second antenna.
[0066] It should be noted that, in the embodiments of this application, see... Figure 5 For the scheme where the main lobe of the third antenna covers both the first ground region and the first space region, the first base station is configured with two SSBs: a first SSB and a second SSB. The first and second SSBs use the same frequency but are time-domain staggered. Taking a 4-channel RRU as an example, two channels of the RRU are connected to one column of dual-polarized arrays (the first dual-polarized array), and the other two channels are connected to another column of dual-polarized arrays (the second dual-polarized array). The RRU of the first base station forms a first beam through the first dual-polarized array to transmit the first SSB, and forms a second beam through the second dual-polarized array to transmit the second SSB.
[0067] In the embodiments of this application, in order to ensure that the first terminal supporting drone capabilities camps on the first cell configured with an air beam, i.e., the second beam, as much as possible, so as to ensure minimal interference on the SSB and ensure that it does not disconnect from the network or lose connection, this application also proposes a scheme for cell camping and handover, which will be detailed below.
[0068] In the embodiments of this application, the first base station may further perform the following steps: sending the number of the second SSB so that when the first terminal supporting drone capability is in an idle state and performing cell reselection, it will preferentially choose to camp on the first cell.
[0069] It should be noted that, in the embodiments of this application, the first base station can send the number of the second SSB through system broadcast or other messages. Thus, after the first terminal supporting UAV capabilities identifies this number, it can preferentially camp on the first cell configured with the air-to-ground beam, i.e., the second beam, during cell reselection in the idle state. Furthermore, it will only camp on the ground cell if the signal strength of the second SSB is less than a certain threshold and the SSB of the ground cell is greater than a certain threshold. The ground cell can be the cell of the aforementioned second base station (ground base station), primarily serving ground users (terminals).
[0070] In embodiments of this application, the first base station may further perform the following steps: when the first terminal supporting UAV capability is in a connected state, sending a measurement configuration message to the first terminal; wherein the measurement configuration message instructs the first terminal to perform Layer 1 measurement and report the signal strength and / or quality of SSBs in each neighboring cell; receiving a measurement report sent by the first terminal; wherein the measurement report includes the signal strength and / or quality of SSBs in each neighboring cell; and determining the neighboring cell to which the synchronization signal block with the highest signal strength and / or quality, transmitted via a beam towards a spatial region, belongs, as the target cell for the first terminal to hand over.
[0071] It should be noted that, in the embodiments of this application, connected low-altitude users preferentially hand over to cells configured with a specific air beam, i.e., a beam oriented towards a spatial region. The first terminal reports the signal strength and / or quality of the SSBs of each neighboring cell in its measurement report to the first base station. The first base station can select neighboring cells configured with air beams, which essentially means selecting neighboring cells whose SSBs are transmitted through a beam oriented towards a spatial region, i.e., air beams. The neighboring cell belonging to the SSB with the highest air beam transmission, signal strength, and / or quality is then selected as the target cell for the first terminal's handover. The first base station can inform the first terminal of the target cell through messages such as physical channel reconfiguration. If the signal strength and / or quality of the SSBs in the selected neighboring cells are all below a certain threshold, then a ground cell is considered as the target cell for the first terminal's handover. The ground cell can be a cell of the aforementioned second base station (ground base station), primarily oriented towards the ground user (terminal).
[0072] Based on the above, the technical solution provided in this application selects a small number of base stations from a dense network of existing ground base stations using a sparse spacing between stations. Only existing antennas are added or replaced on the selected base stations to form two beams: one for the space region and one for the ground region. No additional hardware is required, significantly reducing the cost of low-altitude network construction. The first base station covers both space and ground. To reduce SSB and service interference between the air and ground, SSB times are staggered. For service channels, the resources used by the first and second base stations are scheduled as staggered as possible. Due to high uplink traffic in low-altitude areas, the first base station allocates more uplink resources to low-altitude users; conversely, due to high downlink traffic on the ground, the second base station allocates more downlink resources to ground users. Low-altitude users preferentially camp on or switch to cells configured with an air-facing beam (i.e., a beam facing a single space region), reducing user disconnection or dropped calls in low-altitude areas.
