Abstract

The present invention discloses a baseband data storage control method, the method comprising: receiving cell configuration information for each subframe, according to the bandwidth and number of antennas in the cell configuration information to map each cell to a preset cell set, each cell set corresponds to a random storage area; The each cell included in each cell and the corresponding cell parameters of each cell are analyzed, and the storage address of each cell in the random storage area is calculated according to the obtained cell parameters; The received baseband data is stored in the random storage area corresponding to the cell to which the baseband data belongs. The present invention also discloses a baseband data storage control device at the same time.

Description

Technical field [0001] The present 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, as the core of the fourth generation of mobile communications, has problems such as large baseband signal processing 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. These problems arise because the LTE standard communication system has greater flexibility in the configuration of the cell, such as: Time Division Duplexing (TDD, Time Division Duplexing) and Frequency Division Duplexing (FDD, Frequency Division Duplexing) mixing, Mixing of different bandwidths, mixing of different antenna numbers and cross-mixing between the above various...

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 the antennas, but the number of memories is increased proportionally according to the increase in the number of antennas, which is likely to cause 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
