Abstract: Wireless communications systems and methods are provided relating to a physical uplink shared channel (PUSCH) repetition adaptation scheme when one or more PUSCH repetitions are discarded due to collisions. Specifically, a user equipment (UE) may obtain data for uplink transmission over a plurality of repeated PUSCH instances. In response to determining that at least one repeated PUSCH instance collides with one or more downlink symbol transmissions, the UE may discard the at least one repeated PUSCH instance. The UE may then retransmit data that was scheduled to be transmitted over the at least one repeated PUSCH instance over configured resource that was configured for uplink transmission with configured grants.

Abstract: Apparatuses, methods, and systems are disclosed for responding to a new data indicator for a hybrid automatic repeat request process. One method (1200) includes determining (1202) whether a current new data indicator in a current sidelink grant matches a last received new data indicator in a last received sidelink grant for a first hybrid automatic repeat request process. The method (1200) includes, in response to determining that the current new data indicator does not match the last received new data indicator, determining (1204) whether a negative acknowledgement has been transmitted in response to the last received sidelink grant.

Abstract: Embodiments include methods for a user equipment (UE) configured to operate in a radio access network (RAN). Such methods include obtaining data for transmission during a particular one of a plurality of periodic occasions during which the UE has been granted resources for uplink data transmission. The data includes first and second protocol data units (PDUs) associated with respective first and second hybrid ARQ (HARQ) processes. At least one of the first and second PDUs is for retransmission after failed transmission during an earlier one of the occasions. Such methods include selecting the first PDU or the second PDU for transmission during the particular occasion based on at least one of the following: priorities of logical channels with data included in the first and second PDUs, and whether one or both of the first and second PDUs are for retransmission. Other embodiments include complementary methods for a RAN node.

Abstract: Systems methods and devices for transmitting a transport block (TB) over multiple slots. A first grant associated with a hybrid automatic repeat request (HARQ) process in a first set of slots is received. A first subset of the first set of slots is determined to be available, and a second subset of the first set of slots is determined to be unavailable, for uplink transmission. The TB is segmented into a first segment and a second segment in response to the determination. The first segment is transmitted in the first subset of the first set of slots. A second grant associated with the HARQ process is received to transmit the TB in a second set of slots. The second segment of the TB is transmitted in the second set of slots.

Abstract: A device (e.g., a wireless transmit/receive unit (WTRU)) may determine which information (e.g., among multiple transport blocks (TBs)) to be sent on resource(s) of a physical uplink channel (PUCCH) transmission occasion of a configured grant (CG). In an example, the device may receive configuration information. The configuration information may indicate a resource associated with the CG. The device may determine whether to transmit (e.g., on the resource associated with CG) first information of a first TB or second information of a second TB based on one or more of downlink feedback information (DPI) reception, a reason why information of a TB (e.g., the first TB or the second TB) has not been sent in a prior transmission, and a nature of the content (e.g., control information vs. data) in the TB. The first TB may comprise the first information and the second TB may comprise the second information.

Abstract: Wireless communication systems and methods related to utilizing two-stage grants for uplink communications with discontinuous reception (DRX) operations are provided. In some aspects, a user equipment (UE) receive, from a base station (BS), a first downlink control information (DCI) message scheduling an uplink (UL) data transmission, the first DCI message indicating a first value for an UL schedule timing indicator. The UE activates a timer based at least in part on the first value of the UL schedule timing indicator. The UE monitors a downlink control channel based at least in part on the timer. The UE receives, from the BS, a second DCI message indicating UL schedule timing for the UL data transmission based at least in part on the monitoring.

Abstract: In an example, a user equipment (UE) may receive, from a base station, a message indicating activation or reactivation of semi-persistent scheduling (SPS) between the UE and the base station. The UE may determine, based on the message, a first resource for transmitting a first acknowledgement / negative-acknowledgement (ACK/NACK) to acknowledge reception of the message. The UE may also receive, from the base station and subsequent to the receiving of the message, an SPS message. The UE may also determine a second resource for transmitting a second ACK/NACK to acknowledge reception of the SPS message. The UE may also transmit, to the base station, the first ACK/NACK on the first resource and the second ACK/NACK on the second resource.

Abstract: Embodiments of the present disclosure provide methods and apparatus for transmitting CSI report. For example, a first aspect of the present disclosure provides a method performed at a terminal device, comprising: transmitting a first CSI report; transmitting a second CSI report; wherein at least a portion of the second CSI report is obtained based on the first CSI report. For example, a second aspect of the present disclosure provides a method performed at a terminal device, comprising: transmitting a first CSI report; and transmitting, to a network node, a change indicator about whether at least a portion of the first CSI report changes. According to embodiments of the present disclosure, the success rate of transmitting a CSI report may be improved and the payload for transmitting a CSI report may be reduced.

Abstract: Methods, systems, and devices for wireless communications are described. A first user equipment (UE) may determine that a second UE is to transmit a control channel message retransmission using a first subchannel of a sidelink control channel during a subframe. The first UE may determine that the first UE is to transmit a sidelink transmission using a second subchannel of the sidelink control channel during the subframe, the second subchannel being different from the first subchannel. The first UE may transmit, by the first UE and during the subframe, the control channel message retransmission of the second UE using the first subchannel and the sidelink transmission of the first UE using the second subchannel.
