PROCÉDÉ D'ENVOI ET DE RÉCEPTION D'INFORMATIONS DE RÉTROACTION, ET ÉQUIPEMENT D'UTILISATEUR ET DISPOSITIF DE RÉSEAU D'ACCÈS

摘要

Embodiments of the present invention provide methods for sending and receiving feedback information, user equipment, and an access network device, relate to the field of communications technologies, and resolve a problem of low uplink resource utilization. In the embodiments of the present invention, UE receives, in a downlink subframe in a preconfigured downlink subframe subset, downlink data that is sent by an access network device by using a downlink shared channel and a DAI index indicator and a DAI total quantity indicator that are sent by using a downlink control channel, determines an uplink subframe used to send feedback information corresponding to the downlink shared channel, then determines a codebook of the feedback information according to the downlink assignment index DAI index indicator and the DAI total quantity indicator, subsequently performs channel coding on the feedback information according to the codebook, and finally sends, in the uplink subframe, the feedback information on which channel coding has been performed to the access network device. The solutions provided in the embodiments of the present invention are applicable during sending of feedback information.
