Abstract: Aspects presented herein may enable a UE to limit MCS and/or K1 offset used for communicating with a base station to a threshold based at least in part on an SCS used for the communication. In one aspect, a UE limit at least one of an MCS to being less than or equal to an MCS threshold or a K1 offset to being greater than or equal to a K1 offset threshold based on a subcarrier spacing selected for communication with a base station, the K1 offset being a number of slots between receiving DL data and transmitting ACK/NACK feedback. The UE communicate with the base station based at least on one of the MCS being less than or equal to the MCS threshold or the K1 offset being greater than or equal to the K1 offset threshold.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may detect, while transmitting data using at least one first bandwidth on at least one sidelink channel to at least one other UE, one or more failures of a listen-before-talk (LBT) procedure within an amount of time. The UE may transmit, to at least one of a base station or the at least one other UE, a report indicating the one or more failures. Numerous other aspects are described.

Abstract: Various procedures associated with autonomous uplink (AUL) are disclosed. In order to address the mismatch between listen before talk (LBT) and AUL bandwidth a fractional sensing channel is defined less than 20 MHz. Accordingly, a user equipment (UE) may use the fractional sensing channel to perform LBT only on the resources allocated for AUL. Contention window update may further be modified for transmissions spanning multiple transmission opportunities (TxOPs). A contention window update may occur over all transmission channels considering full acknowledgement information of each TxOP, a percentage of acknowledgement information weighted on the number of channels, a percentage of acknowledgement information weighted on the ratio of resources on each channel, or by selecting a primary channel of the multiple channels for the contention window update. In repetition scenarios, the reference transmission for contention window updates may be selected depending on whether all repetitions are within one or multiple TxOPs.

Abstract: This disclosure provides systems, methods, apparatuses, and computer-readable media for multiplexing channel state information (CSI) reports in scenarios involving multiple transmit-receive points (TRPs). In one aspect, a user equipment (UE) may receive at least one configuration that identifies a resource for multiplexing CSI reports that have a potential to collide in a slot. The UE may receive the at least one configuration from either, or both, of a first TRP or a second TRP. The UE may transmit at least one of a first set of CSI reports to the first TRP or a second set of CSI reports to the second TRP, multiplexed in the resource, according to the at least one configuration.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may select, within a resource selection window, a set of resources in which to transmit over an unlicensed sidelink channel. The UE may attempt a listen before talk (LBT) procedure to initiate a channel occupancy time in which to transmit over the unlicensed sidelink channel. The UE may adjust, within at least a portion of the resource selection window, the set of resources in which to transmit over the unlicensed sidelink channel to be contiguous in at least a time domain based at least in part on the LBT procedure succeeding. The UE may transmit, over the unlicensed sidelink channel, using the set of resources that are adjusted to be contiguous in at least the time domain. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a base station, a resource grant for at least one sidelink channel, wherein the resource grant indicates an uplink resource for transmitting sidelink transmission acknowledgement messages. The UE may transmit, to the base station and on the uplink resource, an indication of at least one status associated with a listen-before-talk procedure used on the at least one sidelink channel. Numerous other aspects are provided.

Abstract: A method for wireless communication performed by a user equipment (UE) includes receiving, from a base station on a granting group common (GC)-physical downlink control channel (PDCCH), a multimedia broadcast multicast service (MBMS) downlink grant that schedules an MBMS transmission at each UE of a group of UEs that includes the UE. The method also includes receiving, from the base station on a triggering GC-PDCCH, a message indicating respective feedback resources for each UE of the group of UEs. The method further includes receiving, from the base station, the MBMS transmission. The method still further includes transmitting, to the base station via the feedback resources, a feedback report based on receiving the MBMS transmission.

Abstract: Aspects of the present disclosure can be implemented in a method for wireless communication by a first wireless node, such as a user equipment (UE) or network entity. The method generally includes identifying different patterns of phase tracking reference signal (PTRS) tones for receiving a PTRS, determining when to change at least one of the different patterns of the PTRS tones from one symbol to another, and monitoring for one or more symbols of the PTRS, from a second wireless node, according to the determination.

Abstract: Mechanisms for cross-carrier scheduling from a first cell to a second cell in a wireless networking scheme are provided. In one aspect, a method includes receiving, from a base station (BS), a first configuration for scheduling in a first cell having a first subcarrier spacing (SCS), wherein the first configuration is associated with a first search space in the first cell. The method further includes receiving, from the BS, a second configuration for scheduling in the first cell, wherein the second configuration is associated with a second search space in a second cell, and wherein the second cell is associated with a different second SCS. The method further includes determining a number of blind detections (BDs) based on at least one of the first SCS or the second SCS, and monitoring, based on the number of BDs, for downlink control information (DCI) in the first and second search spaces.
