Abstract: A wireless device may transmit, via an uplink resource, a sub-codebook comprising feedback bits for at least one of: downlink control information (DCI) scheduling a physical downlink shared channel (PDSCH) transmission via code block groups (CBGs); or a multi-PDSCH scheduling DCI (M-DCI). The number of the feedback bits is based on the larger of a first number of schedulable PDSCHs by the M-DCI and a second number of the CBGs.

Abstract: A method performed by a first sidelink (SL) user equipment (UE) includes receiving a downlink control information (DCI) from a number of coupled DCIs. The DCI grants reception of a number of scheduled physical SL shared channels (PSSCHs) over an unlicensed SL carrier, and requests a hybrid automatic repeat request (HARQ) response for the scheduled PSSCHs. The method also includes receiving at least one of the PSSCHs from a second SL UE. The method further includes transmitting the HARQ response based on the at least one received PSSCH.

Abstract: Methods, systems, and devices for wireless communications are described. Generally, the described techniques provide for a user equipment (UE) receiving control messages that schedule a first and second set of repetitions of an uplink transmission to respective transmission/reception points (TRPs). The one or more control messages may be indicative of a first redundancy version (RV) sequence that is to be applied to the first set of repetitions and a second RV sequence that is to be applied to the second set of repetitions. The control messages may also indicate a first set of power control parameters and a second set of power control parameters. The UE may map the first and second set of power control parameters to the first and second set of repetitions according to a rule. The UE may transmit the first and second sets of repetitions according to the respective RV sequences and power control parameters.

Abstract: An apparatus and a method of wireless communication are provided. The method by a user equipment (UE) includes being configured, by a base station, to receive a downlink channel in a set of symbols for a serving cell and reporting, to the base station, an acknowledgement of the downlink channel in an uplink transmission. This can solve issues in the prior art, provide a method to determine an acknowledgement of a downlink channel in an uplink transmission, reduce signaling overhead, provide a good communication performance, and/or provide high reliability.

Abstract: Apparatuses, methods, and systems are disclosed for supporting a mixture of BR and HFBT. One apparatus (600) includes a processor (605) that provides a physical ("PHY") layer (255) and a Medium Access Control ("MAC") layer (260) and a transceiver (625) that communicates on a sidelink channel. The processor (605) determines (805) a minimum time duration between a first resource for HARQ transmission of the transport block ("TB") and a second resource for HARQ transmission of the TB. Here, the minimum time duration comprises a sum of: a first time to receive HARQ feedback, a second time to determine whether to perform retransmissions of the TB, and a third time to retransmit the TB. The processor (605) selects (810) a retransmission mode based on the minimum time duration and selects (815) sidelink resources for retransmission of the TB based on the selected retransmission mode.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may selectively determine to decode a downlink shared channel multicast transmission based on whether the downlink shared channel includes a retransmission of an initial multicast transmission. A base station may transmit a message in a downlink control channel to indicate if the downlink shared channel is carrying the retransmission of the initial multicast transmission. For example, the base station may transmit a group random network temporary identifier, downlink control information with a retransmission indicator bit, or both to indicate if the downlink shared channel is carrying the retransmission. In some cases, the message in the downlink control channel may be received at a layer one (L1) of the UE, and the downlink shared channel transmission may be decoded at L1 of the UE and sent to a layer two (L2) of the UE for processing.
