Abstract

The invention discloses a method, receiving equipment and a system for realizing data feedback. In the scheme of the invention, on a back haul link of a relay network, a receiving terminal generates a piece of compressing feedback information aiming at a plurality of receiving results of TB from a transmitting terminal and sends the compressing feedback information to the transmitting terminal. Thus, the scheme of the invention fully considers the characteristics and the special requirements of transmission on the back haul link, provides a realization mode of compressing feedback, and designs the concrete realization of HARQ of the back haul link. Because in the scheme of the invention, only a piece of compressing feedback information needs to be sent to the transmitting terminal aiming at a plurality of receiving results of the TB, the feedback process can be simplified, the feedback cost can be reduced, and the conflict between the back haul link and an access link can be avoided furthest; and meanwhile, the invalid retransmission can be avoided, the loss of feedback signaling can be reduced, and the service efficiency of wireless resources is improved.

Description

technical field

[0001] The present invention relates to the relay field, in particular to a method for realizing data feedback, a receiving device and a system. Background technique

[0002] As an emerging technology, relay technology has attracted more and more attention and is regarded as the key technology of the next generation mobile communication system (B3G / 4G). Since future wireless communication or cellular systems require increased coverage and support for higher-speed transmission, this poses new challenges to wireless communication technology; at the same time, the cost of communication 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, the traditional single-hop link can be divided in...
