Abstract: A method of data retransmission can include receiving a transport block (TB) including code block groups (CBGs) corresponding to a first hybrid automatic repeat request (HARQ) process from a transmitter at a receiver in a wireless communication system, and transmitting a TB/CBG indicator along with HARQ retransmission information from the receiver. The HARQ retransmission information includes a HARQ acknowledgement (HARQ-ACK) feedback or a retransmission indication for the first HARQ process. The TB/CBG indicator indicates whether the HARQ-ACK feedback or the retransmission indication is TB-level or CBG-level.

Abstract: User equipment (UE) for semi-static downlink (DL) scheduling is provided. The UE may include a radio frequency (RF) signal processing device and a processor. The RF signal processing device is configured to receive radio resource control (RRC) information from a base station. The processor is coupled to the RF signal processing device. When the RF signal processing device receives a first configuration of a semi-static DL scheduling and a higher layer parameter from the RRC information, the processor determines not to receive the semi-static DL scheduling in a set of symbols if the RF signal processing device does not receive a downlink control information (DCI) from the base station.

Abstract: In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may be a UE. The UE receives, from a base station, one or more downlink reference signals on an unlicensed carrier. The UE determines that the base station occupies the unlicensed carrier for a predetermined first channel occupancy time based on the one or more downlink reference signals. The UE receives, on the unlicensed carrier and in the predetermined first channel occupancy time, a control burst including a plurality of down link control channels. The UE attempts to decode a first down link control channel directed to the UE from the control burst.

Abstract: Examples pertaining to dynamic beam indication for network-controlled forwarding in mobile communications are described. An apparatus (e.g., a network-controlled repeater (NCR)) may receive downlink control information (DCI) from a network node. The DCI may include first beam indication information indicating one or more first pairs of a spatial setting and a time-domain resource. The apparatus may also forward a radio signal based on the first beam indication information.

Abstract: A method for providing multiple physical uplink control channel (PUCCH) resources for a uplink control information (UCI) report can include receiving one or more PUCCH resource configurations from a base station (BS) at a user equipment (UE) in a wireless communication system, and determining a first PUCCH resource configuration from the one or more PUCCH resource configurations for reporting a UCI. The first PUCCH resource configuration can indicate multiple frequency domain transmission occasions in a bandwidth. The UCI can be transmitted on at least one of the multiple frequency domain transmission occasions indicated by the first PUCCH resource configuration.

Abstract: Aspects of the disclosure further provide an apparatus and a method for wireless communication. The apparatus includes processing circuitry that receives, from a base station (BS), a downlink (DL) grant scheduling an uplink (UL) transmission to the BS. The DL grant indicates a first type of channel access procedure for the UL transmission. The processing circuitry further receives channel occupancy information for a channel occupancy that is initiated by the BS. The processing circuitry switches, from the first type of channel access procedure, to a second type of channel access procedure for the UL transmission according to the first type of channel access procedure and the channel occupancy information.

Abstract: A system for acquiring channel knowledge and a method thereof are provided. At least one transmitter generates multiple directional beams in different directions, next modulates the directional beams in the different directions by means of at least one spreading sequence, so as to enlarge the beam range of each directional beam in the different directions and use the modulated directional beams as training-specific beams in the different directions, and sweeps the training-specific beams in the different directions by means of a plurality of antennas, so that at least one receiver measures at least one training-specific beam, and determines the channel knowledge according to the measurement result and beam-related information associated with the at least one training-specific beam, so as to achieve a technical effect of reducing training overhead.
