Problems solved by technology

[0017] This technical solution stores the data of all transmission channels in a large memory, and after all the transmission channels are stored, the 10ms data after one interleaving is selected for subsequent processing, so that the realization of one interleaving is compared It is convenient and intuitive, but it still has such a shortcoming: that is, it does not take into account that an interleaving is actually performed in units of 10ms each. Using this technical solution will undoubtedly increase the overhead of the memory. In addition, when the solution is implemented, It is necessary to make multiple judgments on the specific storage location of the data, which also increases the difficulty of logical processing of the hardware to a certain extent.

Embodiment Construction

[0042] The technical scheme of the present invention will be described in further detail below in conjunction with the accompanying drawings and specific examples, so that those skilled in the art can better understand the present invention and implement it, but the examples given are not intended to limit the present invention .

[0043] Core train of thought of the present invention is:

[0044] (1) The present invention does not need to sort the TTIs of 8 transmission channels according to their size, but completes the processing of each 10ms of each transmission channel in turn;

[0045] (2) The present invention utilizes the characteristics of one-time interleaving processing: promptly take each 10ms as a unit, so it is not necessary to store the data of all transmission channels in a large memory and select 10ms for processing, but directly only store the current A 10ms data to be processed reduces the capacity of the original interleaving memory for the first time from...

Abstract

The invention discloses a TD-SCDMA uplink transmission channel processing method. By the method, the processing of each 10 ms of each transmission channel is successively finished, and ordering processing of the TTIs of eight transmission channels according to size is unnecessary, so that the processing logic complexity is reduced. By using the method, it is unnecessary to store data of all the transmission channels in a large memory to select the 10 ms for processing, instead, data of one 10 ms currently to be processed is directly stored only, and data selection is finished by use of a memory, such that the realization is visual and convenient, the logic processing difficulty in determining a data storage position is reduced, the requirement for interlacing the storage space of the memory at a time is reduced, and the effect of optimizing a whole uplink area is achieved.

Description

technical field [0001] The present invention relates to the field of wireless mobile communication and signal processing systems, in particular to a TD-SCDMA (Time Division Duplex-Synchronous Code Division Multiple Access, Time Division Duplex-Synchronous Code Division Multiple Access) uplink transmission channel processing method, It is applied to the processing of the uplink transmission channel of the TD-SCDMA baseband chip processing system. Background technique [0002] In the wireless mobile communication and signal processing system, the uplink is the signal transmission link from the terminal UE to the base station NodeB. For the uplink, its main processing includes the processing of the transmission channel part and the physical channel part. [0003] Among them, the transmission channel processing mainly includes cyclic redundancy check code (Cyclic Redundancy Code, CRC for short) addition, channel coding, first interleaving, rate matching and transmission channel ...
