Problems solved by technology

[0034] From the above analysis, it can be seen that the uplink enhancement method in the FDD system is not completely applicable to the TDD system, and its signaling content is relatively large, which brings a relatively large signaling burden
However, there are still many problems in the shared physical control channel transmission method used in HSDPA technology

Abstract

A method for transmitting control signaling of data transmission reinforcement correlation in mobile communication system includes realizing time and rate dispatch by utilizing absolute power command configuration and coding efficiency command configuration. It features that load of down link physical layer control signaling can be much reduced since only transmission power command configuration and coding efficiency command configuration are required in down link signaling with no transmission of transmitting format combination set command configuration and transmitting initial time as well as transmitting time internal.

Description

technical field [0001] The invention relates to a control signaling transmission method related to data transmission enhancement in a mobile communication system, in particular to a physical layer signaling and a transmission method thereof for data service transmission enhancement in a mobile communication system. Background technique [0002] Since wireless communication systems are affected by limited frequency resources, severe mutual interference, and fading channels, how to improve the spectral efficiency of the system has always been the focus of wireless communication. [0003] At present, in downlink packet data transmission, the High Speed ​​Downlink Packet Access (HSDPA) technology has been proven to be a very effective communication method. The steps of this method are as follows: [0004] ●The base station broadcasts the pilot signal to provide the user equipment for channel estimation; [0005] ●The user equipment reports the measurement results to the base s...
