Description

technical field [0001] The invention relates to data storage control technology in the field of wireless communication, in particular to a baseband data storage control method and device. Background technique [0002] Long Term Evolution (LTE, Long Term Evolution) technology is the core of the fourth-generation mobile communication. Its baseband signal processing has a large amount of data, high algorithm complexity, high implementation overhead, and strict requirements on delay restrictions in the processing process. , has always been the focus of research in the field of mobile communications. The emergence of these problems is due to the greater flexibility of the LTE standard communication system for the configuration of the cell, for example: the mixing of time division duplex (TDD, Time Division Duplexing) and frequency division duplex (FDD, Frequency Division Duplexing), Mixing of different bandwidths, mixing of different numbers of antennas and cross-mixing between ...

AI Technical Summary

Problems solved by technology

[0005] 1) If the baseband data is only divided and stored based on different antennas, it is impossible to distinguish cell data with different bandwidths on the same antenna. Therefore, the scheduling and selection of multiple cell data is not flexible enough;

[0006] 2) There is no detailed analysis and consideration of whether the storage space can be reused between antennas, but the number of storage devices is increased proportionally according to the increase in the number of antennas, which may lead to redundant waste of resources;

[0007] 3) The baseband data is received and stored according to the chronological order of the wireless frames, and the data is not classified according to the attributes of the cell and antenna. This data storage method is not conducive to addressing a certain segment of data, so it cannot satisfy the requirements for Data Processing under Flexible Scheduling of Base Stations

[0008] Therefore, in the prior art, the baseband data storage control method generally has the problem of classifying and storing the received data on a single attribute. Corresponding storage, storage according to different cells, or centralized data storage without any attribute induction cannot flexibly adapt to the processing requirements of complex cell configurations in the base station, and may also cause redundant consumption of data storage
