Description

Technical Field

[0001] This invention relates to the field of communication technology, and more specifically, to a method, apparatus, base station, and system for improving forward spectrum efficiency through BBframe filling. Background Technology

[0002] 1. The protocol currently supports forward scheduling resources to be sent at the BBframe granularity. Different BBframes support different UEs (User Equipment). Data parsing for different UEs is distinguished by TSN (time slice number). The protocol defines TSN=0 as a broadcast frame, TSN=0xFF as an empty frame, and the remaining TSNs [1,254] ​​can be assigned to UEs. Only one TSN can be filled in a BBframe.

[0003] 2. Since only one TSN can be filled in a BBframe, if the data of a UE is insufficient to fill a BBframe, the remaining resources of the BBframe will be wasted.

[0004] Based on the above two points, current satellite communication systems suffer from low forward spectrum efficiency. In particular, in multi-user, low-data-volume scenarios, there may be a large number of incompletely filled BB frames, resulting in very low utilization of forward spectrum resources and reduced forward data transmission efficiency. Summary of the Invention

[0005] The present invention aims to provide a method, apparatus, base station and system for improving forward spectrum efficiency by filling BBframes, in order to solve the problem of low forward spectrum resource utilization caused by a large number of incompletely filled BBframes in satellite communication systems in the above-mentioned multi-user, small data volume scenarios.

[0007] Furthermore, after the BBframe continues to populate, the user's TSN in the BBframe is modified to 0.

[0008] Secondly, the present invention provides an apparatus for improving forward spectral efficiency by BBframe filling, comprising: The judgment module is used to determine whether there is a BBframe with a resource utilization rate less than the BBframe resource utilization threshold within the current scheduling period; The fill module is used to continue filling the BBFrame if there is a BBFrame whose resource utilization is less than the BBFrame resource utilization threshold.

[0009] Furthermore, the BBframe filling device for improving forward spectral efficiency further includes: The module is modified to change the user's TSN in the BBFrame to 0 after the BBFrame continues to populate.

[0010] Thirdly, the present invention provides a base station in which the above-mentioned device is provided.

[0011] Fourthly, the present invention provides a satellite communication system, including a satellite and a base station, wherein the base station is the aforementioned base station.

[0012] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are: In satellite communication systems, the method for improving forward spectrum efficiency by filling BBframes provided by this invention improves the resource utilization of BBframes, the efficiency of forward spectrum, and the transmission efficiency of forward data.

[0019] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0020] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0021] Example like Figure 1 As shown, this embodiment of the invention provides a method for improving forward spectrum efficiency by filling BBframes. This method is applied when no new BBframe resources are allocated within a scheduling period. It can continue to fill BBframes when the forward spectrum resource BBframes are not fully filled, thereby improving BBframe resource utilization and forward spectrum efficiency. The method includes: Determine whether there is a BBframe whose resource utilization is less than the BBframe resource utilization threshold within the current scheduling period; If there is a BBFrame whose resource utilization is less than the BBFrame resource utilization threshold, continue to populate the BBFrame; the BBFrame resource utilization threshold can be set according to needs and actual application conditions. Furthermore, after the BBFrame continues to populate, the user's TSN in the BBFrame is modified to 0 (broadcast, data parsing does not distinguish between users).

[0022] The following example details the method for improving forward spectral efficiency through BBframe padding.

[0023] First, the effect after the current BBFrame data is filled is as follows: Figure 2 As shown in Table 1, the corresponding resource utilization rate and TSN are shown in Table 1.

[0024] Table 1 shows the resource utilization and TSN after the current BBFrame data is populated.

[0025] After using the method of this invention, the effect of BBFrame data filling is as follows: Figure 3As shown in Table 2, the corresponding resource utilization rate and TSN are shown in Table 2.

[0026] Table 2 shows the resource utilization and TSN after BBframe data filling using the method of the present invention.

[0027] Therefore, the method of this invention allows for the continued filling of other users' data when the resource utilization of the BBframe is less than a certain threshold, until the BBframe is fully filled or a certain resource utilization threshold is reached, thereby improving forward spectrum efficiency.

[0028] Based on the same technological concept, such as Figure 4 As shown, this embodiment of the invention also provides an apparatus for improving forward spectral efficiency by BBframe filling, comprising: The judgment module is used to determine whether there is a BBframe with a resource utilization rate less than the BBframe resource utilization threshold within the current scheduling period; The fill module is used to continue filling the BBFrame if there is a BBFrame whose resource utilization is less than the BBFrame resource utilization threshold.

[0029] Furthermore, the device also includes: The module is modified to change the user's TSN in the BBFrame to 0 after the BBFrame continues to populate.

Figure 5 As shown, the base station is equipped with the aforementioned device.

Figure 6 As shown, the base station is the one described above.
