Distribution method and device for quick feedback channel

Abstract

The invention discloses a distribution method and a distribution device for a quick feedback channel. The method comprises the following step of: distributing the next time slot when the quick feedback channel is distributed to a mobile terminal and after idle distribution bits of the last time slot are fully distributed. The device comprises a quick feedback channel distribution unit for distributing the next time slot when the quick feedback channel is distributed to the mobile terminal and after the idle distribution bits of the last time slot are fully distributed. After the last time slot is fully distributed, the next time slot is distributed so as to effectively improve the utilization rate of uplink spectrum resources. In addition, when the acknowledgement character (ACK) of a hybrid automatic repeat request (HARQ) occupies the quick feedback channel area, the mobile terminal is informed to perform channel information feedback in a spare channel information feedback mode, and a base station can learn the channel information in real time and makes various adjustments according to the channel information, so function balance of the ACK channel area of the HARQ and the quick feedback channel area is achieved.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a fast feedback channel allocation method and device. Background technique [0002] Orthogonal Frequency Division Multiple Access (OFDMA, Orthogonal Frequency Division Multiple Access) is a special multi-carrier transmission technology, which changes the data stream through series and parallel, and distributes it to several sub-channels for transmission, which greatly improves the spectrum efficiency. Effectively combating multipath interference and narrowband interference has become one of the core technologies of the next generation mobile communication system. WIMAX (Worldwide Interoperability for Microwave Access), using OFDMA technology as its physical core technology, and taking into account the characteristics of mobility and broadband, according to IEEE802.16e and IEEE802.16m standard WIMAX technology, has become the next generation of mobile A str...
