Abstract: Data transmission and reception is provided by configuring control channels in a wireless communication system using a plurality of carriers. User equipment (UE) may monitor physical downlink control channel (PDCCH) candidates within common search spaces (CSSs) and User Equipment-specific search spaces (USSs). If the UE is configured with cross-carrier scheduling, when two PDCCH candidates originating from a CSS and a USS, respectively, have cyclic redundancy check (CRC) scrambled by the same Radio Network Temporary Identifier (RNTI) and have a common payload size and the same first control channel element (CCE) index, the UE may interpret that only the PDCCH originating from the CSS is transmitted, thereby solving ambiguity of downlink control information (DCI) detection.

The present application further provides UE and a corresponding base station. By means of the technical solution of the present application, the data transmission interruption time in the handover procedure in the NR can be further reduced, and an unnecessary incorrect handover is avoided.

Abstract: A method, an apparatus, a base station, and a user equipment (UE) for wireless communication are provided to reduce the retransmission latency for URLLC communications. Upon receiving a downlink data transmission, a UE waits until it completes decoding of the received downlink data transmission before it can send an ACK/NAK report on the decoded downlink data transmission. In case of a decoding failure, the base station cannot start retransmission until the UE finishes the decoding of the downlink data transmission and sends the ACK/NAK report and until the base station finishes decoding of an NAK in the ACK/NAK report. This considerable retransmission latency may not meet stringent latency requirements of some URLLC applications. A two-stage ACK/NAK reporting is disclosed to reduce the retransmission latency where the UE sends an early ACK/NAK report upon partially completing the decoding of the downlink data transmission.

Abstract: Methods and apparatuses for transmitting and receiving HARQ-ACK information. A method of operating a UE includes receiving: a configuration for a first group index for first control resource sets (CORESETs), physical downlink control channels (PDCCHs) in CORESETs, wherein the PDCCHs provide respective downlink control information (DCI) formats scheduling respective receptions of physical downlink shared channels (PDSCHs), and the PDSCHs corresponding to the PDCCHs.

Abstract: Hybrid automatic repeat request (HARQ)-acknowledgement (ACK) feedback codebook enhancements are disclosed. A size of feedback codebook may be reduced explicitly or implicitly. For example, an indicator may be identified by a corresponding field of a downlink control message. In some aspects, the indicator may indicate that multiple Physical Downlink or Uplink Shared Channels (PDSCHs/PUSCHs) are actually scheduled during one or more slots of a window corresponding to the feedback codebook. Responsive to receiving the indicator, a device may refrain from reducing the size of the feedback codebook to exclude acknowledgement feedback for additional possible PDSCH/PUSCH occasions of the slots of the window. In some aspects, a device identifies possible PDSCH/PUSCH occasions that occur outside of one or more Channel Occupancy Times (COTs) of a window. The device may generate a reduced size feedback codebook by excluding the possible PDSCH/PUSCH occasions that occur outside of the COTs of the window.
