Problems solved by technology
[0006] In the base station modulation processing, the channel modulation processing resources between cells cannot be shared, and the modulation processing resources between R99, HSDPA, and HSUPA channels cannot be shared, resulting in waste of resources and greatly affecting the performance specifications of base station products
Especially when the size of the cell becomes larger, the modulation resources increase linearly, but the total user size of all the cells in practical applications is limited, which is less than the maximum number of users multiplied by the number of cells in a single cell, resulting in a waste of modulation resources
Moreover, the existing base station configuration method is based on specific settings for different cells and channels, cannot support protocol evolution, cannot predict new channels in the future, and has limited flexibility

Embodiment Construction
[0050] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.
[0051] In order to solve the problems in the prior art, an implementation method of channel processing resource sharing based on a unified channel model is proposed in the embodiment of the present invention. By making the channel format unified, the processing flow unified, the timing unified, and the parameters unified, the cells between , R99 / HSDPA / HSUPA channels share resource pools become a reality.
[0052] The unified channel model in the embodiment of the p...

An embodiment of the invention discloses a data modulation method and device. The data modulation method is used for a base station of a universal mobile communication system (UMTS) and comprises the steps of obtaining data to be modulated, wherein the data to be modulated are downlink channel transmitted data; performing data frame mapping treatment on the data to be modulated according to the downlink channel types of the data to be modulated or / and domain parameters corresponding to cells to obtain data frames unified in frame format; performing timing treatment on the data frames unified in frame format according to the downlink channel types of the data to be modulated or / and timing parameters corresponding to the cells to obtain data frames unified in timing; performing channel modulation on the data frames unified in timing according to modulation parameters of the data to be modulated to obtain modulated data. By adopting the data modulation method and device, the data different in channel type and data of the cells can be subjected to unified modulation, and resource waste can be remarkably reduced.
Description
technical field [0001] The invention relates to the field of wireless communication, in particular to a data modulation method and device. Background technique [0002] Universal Mobile Telecommunications System (UMTS) physical layer downlink processing includes coding and modulation, wherein modulation plays a key role in the base station downlink processing of the UMTS system that affects the performance and specifications of the base station. [0003] There are many types of existing UMTS downlink channels, such as Release 99 (Release 99, R99) dedicated channels, specifically including: Dedicated Physical Channel (Dedicated Physical Channel, DPCH) and F-Dedicated Physical Channel (Fractional Dedicated Physical Channel, F-DPCH) ); R99 common channels, specifically including: Primary Synchronization Channel (P-SCH), Secondary Synchronization Channel (Primary Synchronization Channel, S-SCH), Primary Common Pilot Channel (PrimaryCommon Pilot Channel, P-CPICH), auxiliary Comm...
