Abstract

The present invention discloses a method for processing Channel Quality Information (CQI). The method is used in backhaul link and includes the following steps: coding the generated CQI and obtaining the coded information; scrambling the coded information and obtaining the scrambled sequence; modulating the scrambled sequence and obtaining the modulated complex-valued symbol sequence; spreading the modulated complex-valued symbol sequence in frequency-domain and obtaining the frequency-domain spread complex-valued symbol sequence; mapping the frequency-domain spread complex-valued symbol sequence onto the physical resources of Physical Uplink Control Channel (PUCCH), wherein the physical resources are configured by the system. The present invention also discloses an apparatus for processing CQI. The present invention effectively enables the Relay Node (RN) to carry the backhaul link CQI on PUCCH of the backhaul link and to transmit the CQI to the Evolved Node B (eNB).

Description

technical field [0001] The invention belongs to the field of mobile communication, and in particular relates to a processing method and device for a channel quality report 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, the traditional single-hop link can be divided into ...
