Title:
METHOD AND APPARATUS FOR SENDING HYBRID AUTOMATIC FEEDBACK RETRANSMISSION ACKNOWLEDGE/NEGATIVE-ACKNOWLEDGE INFORMATION
Document Type and Number:
WIPO Patent Application WO/2021/062818
Kind Code:
A1
Abstract:
Disclosed are a method and apparatus for sending hybrid automatic feedback retransmission acknowledge/negative-acknowledge information, which relate to the field of communications and provide a mechanism for feeding back information on whether a decoding result is correct or not for downlink data that is repeatedly transmitted within a time slot. The method comprises determining a first downlink data timing set according to time domain resources indicated by a TDRA table, and determining a first downlink data timing according to an initial time domain resource for sending downlink data, and carrying feedback information (e.g.: information on whether the decoding result of the downlink data is correct or not) at a feedback position corresponding to the first downlink data timing. In addition, a feedback time slot is determined according to the time slot to which the initial time domain resource for sending the downlink data belongs as well as a first offset value K1, and a HARQ-ACK codebook is fed back on the feedback time slot.
