Abstract:
Some techniques and apparatuses described herein provide reporting of multiple feedbacks for a same transport block (TB) or a same code block group (CBG) of a signal, such as a physical downlink shared channel. Thus, in case of a failure to decode a signal via a first set of antennas, a user equipment (UE) can perform a second decoding attempt via a second set of antennas (before or after transmitting first feedback). The UE may report a result of the first decoding attempt in a first feedback, and may report a result of the second decoding attempt in a second feedback. Some techniques and apparatuses described herein also provide soft feedback (e.g., information other than a binary acknowledgment (ACK) or negative ACK (NACK)) for a transmission, such as information indicating whether a second attempt to decode the transmission is likely to be successful.
