Problems solved by technology

If the information with special significance is still processed in the same single sampling method as other common downlink signals, it will affect the performance of the entire business data
[0008] Moreover, according to the provisions of the 3GPP 25.102 protocol, the downlink channels E-AGCH, E-RGCH and E-HI CH in HSUPA require a margin (margin) of 2.5 to 3dB, and from the simulation results, in the current specific implementation , E-AGCH, E-RGCH and E-HICH can only reach a margin of about 1dB, or even less than 1dB
That is to say, if the existing reception processing method is still used for E-AGCH, E-RGCH and E-HICH, the performance requirements specified in the agreement cannot be met

Abstract

The invention relates to a communication system and discloses a method for sampling a received signal by using terminal equipment and the terminal equipment. In the invention, the terminal equipment adopts different sampling processing modes according to the difference of received information contents and/or channels. Oversampling processing instead of the conventional single sampling is performed on received specific information and/or a signal in a specific channel. The signal-to-noise ratio of the received signal can be increased in an oversampling processing mode, so that decoding correctness of important information can be ensured by performing the oversampling processing on the specific information and/or the signal in the specific channel. Therefore, the performance of service datais improved, and the requirements of certain channels on performance can be met.

Description

technical field [0001] The invention relates to a communication system, in particular to a terminal equipment receiving technology in the communication system. Background technique [0002] With the development of mobile communication technology, 3G technology is also constantly evolving. Many data services that require high traffic and delay, such as video, streaming media, and downloads, require the system to provide higher transmission rates and shorter delays. High Speed ​​Downlink Packet Access (HSDPA for short) It is an important evolution of 3G technology. [0003] As a downlink high-speed data packet access technology, HSDPA was introduced into the 3rd Generation Partnership Project (3rd Generation Partnership Project, referred to as "3GPP") Release 5 (Release 5, referred to as "R5") in 2002. In order to realize the high-speed transmission of user downlink data, HSDPA adds two downlink physical channels and one uplink physical channel, which are high-speed physical...
