Patent ID: 10727987

Abstract:
Various features related to a single bit ACK/NACK feedback for CBG based transmissions in a communication system are described. In an aspect, a base station may transmit, to a UE, a set of CBGs of a TB including a first subset of CBGs and a second subset of CBGs, the first subset of CBGs being transmitted on at least partially punctured resources. The base station may receive an ACK/NACK from the UE based on the transmitted set of CBGs, and retransmit to the UE one of the full set of CBGs or the first subset of CBGs based the received ACK/NACK. In an aspect, a UE may decode the set of CBGs received from the base station, transmit ACK/NACK feedback based on a result of the decoding, and receive, based on the transmitted ACK/NACK feedback, a retransmission of either the full set of CBGs, or the first subset of CBGs.
