Abstract

A method used on the backhaul link for handling the hybrid automatic repeat request (HARQ) uplink feedback information is provided by the present invention. The method includes the following steps: generating one item or multiple items of feedback information for the received data, getting the feedback information sequence by coding; getting the feedback information sequence after modulation; getting the complex valued sequence after frequency domain spread; getting the complex valued sequence after time domain spread; and mapping the complex valued sequence after time domain spread to the system-configured physical resources of the physical uplink control channel on the backhaul link; or channel multiplexing for the multiple complex valued sequences after time domain spread, getting the multiplexed sequence, mapping the multiplexed sequence to the system configuration physical resources of the physical uplink control channel on the backhaul link. A device for handling the HARQ uplink feedback information is also provided by the present invention. The present invention can make full use of the channel condition of the backhaul link and improve the transmission efficiency of the uplink feedback information of the backhaul link.

Description

technical field [0001] The invention belongs to the field of mobile communication, and in particular relates to a processing method and device for Hybrid Automatic Repeat request (HARQ) uplink feedback information (ACK / NACK) of a backhaul link (Backhaul Link). Background technique [0002] Relay (Relay) technology, as an emerging technology, has attracted more and more attention, and is regarded as a key technology of B3G / 4G. Since future wireless communication or cellular systems require perfect network coverage and support for higher rate transmission, this poses new challenges to wireless communication technology. At the same time, the cost of system construction and maintenance is more prominent. With the increase of transmission rate and communication distance, the problem of battery energy consumption has become more prominent, and future wireless communication will use higher frequencies, resulting in more serious path loss attenuation. Through the relay technology,...
