Method, system and equipment for transmitting and receiving command words

Abstract

The embodiment of the invention relates to the technical field of wireless communication, in particular to a method, a system and equipment for transmitting and receiving command words, which are used for solving the problems that the accuracy and the validity of base station scheduling are reduced, intersymbol interference is increased, and the throughput of the system is reduced due to the unguaranteed performance of the command words existing in the prior art. The method comprises the following steps that: a send side determines the positions of a first command word and a second command word in a time slot respectively; the send side takes the partial position or the whole position of the second command word as the position of the first command word; and the send side fills the commandwords at the corresponding position of the time slot and sends the command words through channels. The partial position or the whole position of the second command word is used as the position of thefirst command word, so that the performance of the command words and the accuracy and the validity of the base station scheduling are improved, the intersymbol interference is reduced, and the throughput of the system is increased.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a method, system and equipment for transmitting and receiving command words. Background technique [0002] Since the CDMA (Code Division Multiple Access, Code Division Multiple Access) system is an interference-limited system, the CDMA system is very sensitive to changes in signal transmission power. Power control and reasonable scheduling on the network side can control interference between users and improve power utilization, thereby improving user capacity and call quality of the entire system. [0003] The power control can be divided into inner loop power control and outer loop power control. The inner-loop power control mainly compares the received signal-to-noise ratio with the target signal-to-noise ratio, and carries the inner-loop power control adjustment command through the TPC (Transmit Power Control, transmit power control) command word. The ...
