Problems solved by technology

[0008] However, the reverse CDMA users in the same sub-segment use the same basic node to transmit reverse data. The current ACK channel cannot carry multiple ACK bit information for a certain basic node, but can only carry one ACK bit information for a certain basic node.
Therefore, the current ACK channel cannot carry the acknowledgment information for the reverse CDMA users using the basic node

Abstract

The present invention discloses a device and a method for forward acknowledge information transmission used for a wireless communication system. The device comprises a first keying modulation module, a first channel gain adjusting module and a first discrete Fourier transforming module, wherein the first keying modulation module is used to respectively modulate one channel or multi-channel acknowledge information bit to be acknowledge symbols through a keying modulation method; the first channel gain adjusting module is used to respectively adjust the power of each channel acknowledge symbols according to the forward channel quality; the first discrete Fourier transforming module is used to the Fourier transformation for the acknowledge symbols after whose poser is adjusted, and the multi-channel acknowledge symbols after being transformed are transmitted to a downstream device for the SSCH channelizing processing after performing parallel-serial transformation. The present invention enables the ACK channel to transmit the answer message for a reverse OFDMA user, and simultaneously enables the ACK channel to transmit the answer message for a reverse CDMA user through expanding the ACK channel at present.

Description

technical field [0001] The present invention relates to the communication field, and more specifically relates to a device and a method for sending forward acknowledgment information used in a wireless communication system. Background technique [0002] Third Generation Mobile Communication Cooperation Project Organization 2(3 rd In order to compete with 3GPP LTE and Wimax, generation partnership project 2 (3GPP2 for short) proposes a new air interface evolution plan (Air Interface Evolution, AIE for short). AIE adopts new air interface technologies, such as Orthogonal Frequency Division Multiplexing (OFDM), Multiple Input Multiple Output (MIMO), and interference cancellation technologies, so as to greatly increase the frequency spectrum Efficiency, data peak rate to meet the competition of future wireless communication. [0003] In order to support a large number of voice over IP (Voice over IP, VoIP for short) users or low-speed delay-sensitive services, the reverse lin...
