Abstract: Methods, systems, and devices for wireless communications are described. A base station may configure a user equipment (UE) with a frequency resource for a multicast/broadcast service (MBS) for the UE to monitor for one or more group-common downlink control channels. The base station may transmit an indication, such as an explicit indication, of a monitoring condition for the group-common downlink control channels within the frequency resource. The UE may apply the monitoring condition by enabling or disabling the group-common downlink control channel monitoring within the frequency resource. The UE may monitor one or more downlink control channels for scheduling information from the base station according to the monitoring condition.

Abstract: The disclosure relates to methods, devices, and systems for wireless communications. In some wireless communications systems, a base station may transmit a multicast message to a group of user equipment (UEs), and the UEs may provide feedback for the multicast message. In some implementations, the base station may configure the UEs to transmit feedback for multicast messages. In some example, the UEs may transmit group-negative acknowledgment (NACK) feedback information for multicast messages that are not successfully received at the UEs. In some other examples, each UE may be configured with UE-specific uplink control channel resources for transmitting hybrid automatic repeat request (HARQ) feedback for a multicast message. In some implementations, a UE may support feedback for both unicast and multicast messages. The semi-static codebook for unicast, multicast, or both may account for whether the UE is capable of concurrently receiving unicast and multicast messages in a slot.

Abstract: Methods, systems, and devices for wireless communications are described that provide for managing transmissions using multiple component carriers (CCs) in which transmissions using one or more of the CCs may span less than a full transmission time of a slot or other transmission time interval. A UE may signal a capability to transmit such transmissions, and one or more capabilities related to carrier aggregation that may be used by a base station for scheduling of transmissions on different CCs. In the event that overlapping transmissions on two or more CCs exceed a maximum power threshold, various techniques for dropping at least a portion of one or more transmissions of one or more CCs are described.

Abstract: The described techniques provide for the use of sub-band-specific reference signal precoding. A user equipment (UE) may apply multiple precoding matrices to a reference signal to generate a set of precoded reference signals and may transmit the precoded reference signals over respective sub-bands within a given reference signal resource set. In some cases, the UE may transmit a different set of precoded reference signals in each of multiple reference signal resource sets. Upon receiving the precoded reference signals, a base station may perform wideband channel estimation for each sub-band in the given reference signal resource set. The base station may compute an average spectral efficiency for each reference signal resource set and may transmit a report to the UE. The report may include one or more communication parameters for future communications between the UE and base station.

Abstract: Aspects are presented which enable a UE to determine a supplementary uplink (SUL) configuration for an uplink cancellation indication (ULCI) for cancelling uplink communications in SUL. The UE receives from a base station a first configuration associated with a first block of an ULCI and associated with at least one of a SUL carrier a non-supplementary uplink (NUL) carrier in a cell. The base station configures the UE with a second configuration associated with a second block of the ULCI and associated with a SUL carrier in the cell, and the UE determines the second configuration. The UE monitors the ULCI based on the first configuration and the second configuration.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive control information for a communication of the UE; and determine whether the control information is associated with a slot-based control configuration or a non-slot-based control configuration based at least in part on the control information; or determine whether the communication is associated with a slot-based data configuration or a non-slot-based data configuration. Numerous other aspects are provided.

Abstract: Aspects of the present disclosure relate to wireless communication systems configured to provide user equipment (UE)-specific slot structures based on the individual propagation delay experienced by each UE. In some examples, the duration of uplink transmissions for a particular UE within a slot may be configured based on the propagation delay between the base station and that particular UE. For example, the duration of an uplink burst and/or an uplink traffic transmission may be configured based on the propagation delay. In addition, a downlink burst within a slot may be configured for a particular UE on the propagation delay experienced by that UE. Downlink traffic transmissions may further be configured for the cell based on the maximum propagation delay experienced by the UEs in the cell.

Abstract: Methods, systems, and devices for wireless communications are described. In some examples, a user equipment (UE) may receive, from a base station, a configuration associated with a layer to reference signal port mapping. In some cases, the UE may identify, based at least in part on the configuration, that at least one layer of a set of layers for receiving a downlink transmission from the base station is adapted based on at least one interference layer. In some cases, the adapted layer may be mapped to one or more reference signal ports. The UE may receive the downlink transmission and may decode the downlink transmission based on identifying that the at least one layer is adapted and the layer to reference signal port mapping.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive signaling that indicates whether feedback for each of one or more downlink messages scheduled to be received at the UE is to be single-bit feedback or multi-bit feedback. The UE may monitor for the one or more downlink messages. The UE may generate, based at least in part on the monitoring for the one or more downlink messages, a codebook for reporting the feedback pertaining to each downlink message, the codebook supporting inclusion of both single-bit feedback and multi-bit feedback based at least in part on the signaling. The UE may transmit a feedback message that is based at least in part on the codebook.
