Abstract

See full text

Methods and apparatuses are described herein for providing a single-bit hybrid automatic repeat request (HARQ) feedback and a multi-bit HARQ feedback in a wireless transmit/receive unit (WTRU). For example, a WTRU may receive, via a physical downlink control channel (PDCCH), downlink control information (DCI). The DCI may include a field that indicates a code block group (CBG) based retransmission for at least one transport block (TB). On a condition that the DCI does not include the field, the WTRU may transmit, via a physical uplink control channel (PUCCH), a single-bit HARQ feedback for a TB-based retransmission. On a condition that the DCI includes the field, the WTRU may transmit, via the PUCCH, the multi-bit HARQ feedback for the CBG-based retransmission. The WTRU may be configured to provide the single-bit HARQ feedback for the TB-based retransmission and a multi-bit HARQ feedback for the CBG-based retransmission.
