Patent ID: 11664939

Abstract:
Methods, systems and apparatus are provided for hybrid automatic repeat request (HARQ) processes. A wireless transmit/receive unit (WTRU) may receive first uplink (UL)-downlink (DL) configuration information indicating a first UL-DL configuration, and may receive second UL-DL configuration information indicating a second UL-DL configuration. The WTRU may receive a physical downlink shared control channel (PDSCH) transmission in a DL direction of one or more first symbols in a first subframe. The DL direction of the one or more first symbols may be based on the first UL-DL configuration and the second UL-DL configuration. The WTRU may transmit first acknowledgement (ACK)/negative ACK (NACK) information in a UL direction of one or more second symbols in the first subframe. The first ACK/NACK information may be based on the PDSCH transmission. The UL direction of the one or more second symbols may be based on the first UL-DL configuration and the second UL-DL configuration.
