Problems solved by technology

[0004] However, with the sharp increase in the number of cells, users, and channels in the UMTS downlink, if the existing technical solution is used to configure a set of independent channel modulation resource logic for different types of channels, that is, through simple equipment superposition, it will cause The cost of building and maintaining the network has risen sharply, which cannot protect the early investment of customers

Embodiment Construction

[0039] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0040] see figure 2 , a downlink modulation method is provided in this embodiment, including:

[0041] 101. Acquire uplink data to be modulated, and transmit the data to be modulated to a channel resource pool;

[0042] 102. Perform modulation processing on the data to be modulated by using a channel resource pool, where the channel resource pool is a modulation model obtained by taking a union of modulation modes of various channels supported by the base station.

[0043] In this embodiment, when the bearer channel corresponding to the data to be modulated is a user multiplexing channel, before transmitting the data to be modulated to the channel resource pool, it may further include:

[0044] Acquire uplink control information cor...

Abstract

The invention discloses a descending modulating method and device and belongs to the technical field of communication. The method includes: obtaining ascending data to be modulated, and transmitting the data to be modulated to a channel resource pool; performing modulating treatment on the data to be modulated through the channel resource pool, wherein the channel resource pool is a modulating model obtained by taking the union sets of modulating modes of various channels supported by a base station. Therefore, the same channel modulating logic resources are not needed to be configured for all the channels, and logic resources can be distributed to part of the resource pool selectively, so that the requirements that channel numbers and user numbers in a communication network are increased rapidly can be met, and simultaneously logic resources and power consumption are not increased in multiple mode.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a downlink modulation method and device. Background technique [0002] In the downlink modulation of UMTS (Universal Mobile Telecommunications System, universal mobile communication system), each cell has multiple types of channels that need to be modulated, such as DPCH (Dedicated Physical Channel, dedicated physical channel), F-DPCH (Fractional Dedicated Physical Channel, uplink TPC (Transmission Power Control, transmission power control) dedicated physical channel), HS-PDSCH (High Speed ​​Physical Downlink Shared Channel, high-speed downlink shared physical channel), AICH (Acquisition Indicator Channel, access indication channel), etc. channel. The modulation process of various types of channels mainly includes symbol mapping, diversity coding, spreading, scrambling, power control, channel combining, etc. But for different channels, the specific modulation met...
