Problems solved by technology
However, when the cell provides services for multiple trains at the same time, resource bottlenecks are likely to occur, which affects service perception
In addition, due to the shortage of LTE spectrum resources, in order to ensure the network quality of the large network, it is difficult to allocate more frequency points for the private network. Therefore, it is impossible to solve the problem of limited high-speed rail carrying capacity and insufficient resources through carrier expansion.

The invention discloses a base station subsystem, a signal transmission method, base station equipment and a storage medium. The base station subsystem includes a BBU and more than three chain-covered dual-channel RRUs connected to the BBU. Two RRUs of one RRU The channels are respectively connected to two ports of a dual-polarized antenna, and the polarized receiving end of one polarization direction of all dual-polarized antennas except the dual-polarized antennas corresponding to the RRUs at both ends of the chain is configured as the first cell , the polar receiving end of the other polarization direction is configured as the second cell, the first cell and the second cell provide services for two user terminals in opposite moving directions; the BBU receives the baseband of the user terminal uploaded by the RRU at one end of the chain signal, determine the moving direction of the user terminal according to the position of the RRU at one end of the chain, and allocate corresponding cell resources for the user terminal according to the determined moving direction. Through the base station subsystem of the embodiment of the present invention, the service carrying capacity of the system network can be effectively improved, and the user's perception can be enhanced.
Description
technical field [0001] The present invention relates to the technical field of mobile communication, in particular to a base station subsystem, a signal transmission method, base station equipment and a storage medium. Background technique [0002] At present, the construction plan of the high-speed rail private network adopts the model of dedicated cells and dedicated frequency points, which can overcome the problems of congestion and untimely switching caused by using public network coverage. The coverage mode is realized through the baseband processing unit (BBU), dual-channel remote radio unit (RRU) and high-gain antenna, so as to solve the bottleneck that the eight-channel RRU does not have the cascading capability, reduce the number of inter-cell handovers of high-speed users, and improve service stability sex. [0003] In order to greatly reduce the number of handovers and reselections of high-speed railways under high-speed movement, and maintain the stability and f...
