Abstract

The invention discloses a link self-adaption transmission method and equipment, and the method comprises the following steps: measuring and calculating high-speed downlink shared channel data provided by a network side in a current transmission time interval to obtain a demodulated bit signal-to-noise ratio; querying a channel quality indication mapping table corresponding to the capability levels of user equipment to obtain a data transmission parameter corresponding to the bit signal-to-noise ratio, wherein the channel quality indication mapping table is constructed by the modulated bit signal-to-noise ratio of the high-speed downlink shared channel data in multiple transmission time intervals in advance; and reporting the data transmission parameter for the network side to provide high-speed downlink shared channel data in the next transmission time interval. By using the invention, code rate and modulation mode can be adjusted in a self-adaption manner by the user equipment in theprocess of executing link self-adaption, thus ensuring higher system throughout.

Description

technical field

[0001] The present invention relates to mobile communication technology, in particular to a TD-SCDMA (Time Division Synchronous Code Division Multiple Access, Time Division Synchronous Code Division Multiple Access) mobile communication system when providing HSDPA (High Speed โ€‹โ€‹Downlink Packet Access, high-speed downlink packet access) services A link adaptive transmission method and device. Background technique

[0002] With social development and technological progress, international exchanges and cooperation are becoming more and more frequent. People hope that mobile communication systems can provide interactive multimedia services that integrate voice, images and data, just like fixed networks. WCDMA (Wideband Code Division Multiple Access, Wideband Code Division Multiple Access), cdma2000 and TD-SCDMA, which are the three mainstream standards of the third generation of mobile communication, are all undergoing technical enhancements to adapt to the ever-...
