Title:
METHOD AND APPARATUS FOR TRANSMITTING HARQ-ACK FEEDBACK INFORMATION
Document Type and Number:
WIPO Patent Application WO/2017/192025
Kind Code:
A1
Abstract:
The present disclosure relates to a pre-5th-Generation (5G) or 5G communication system to be provided for supporting higher data rates Beyond 4th-Generation (4G) communication system such as Long Term Evolution (LTE). The present disclosure provides a method for transmitting Hybrid Automatic Retransmission Request Acknowledgement (HARQ-ACK) feedback information. The method may include: a. receiving, by a terminal, data of Physical Downlink Shared Channel (PDSCH) and/or Physical Downlink Control Channel (PDCCH)/enhanced Physical Downlink Control Channel (EPDCCH) indicating the release of Semi Persistent Scheduling (SPS) sent by a base station, and determining HARQ-ACK feedback information of the data of the PDSCH and/or the PDCCH/EPDCCH indicating the release of SPS; b. determining an uplink subframe carring the HARQ-ACK feedback information; c. in the uplink subframe determined, transmitting indicating information of the HARQ-ACK feedback information and the HARQ-ACK feedback information, or, transmitting HARQ-ACK feedback information corresponding to all HARQ processes in a predetermined order. Wherein, the indicating information indicates the PDSCH or the PDCCH/EPDCCH indicating the release of SPS corresponding to the HARQ-ACK feedback information, or the HARQ-ACK feedback information corresponding to all HARQ processes comprises the HARQ-ACK feedback information. The present disclosure may transmit the HARQ-ACK feedback information in time, and save PUCCH resources for transmitting the HARQ-ACK feedback information.
