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 configuration message that indicates a radio resource allocation and a transmission scheme for one or more first configured grant—small data transfer (CG-SDT) occasions and one or more second CG-SDT occasions. The one or more second CG-SDT occasions are at least partially nested, in time, frequency, or a combination thereof, within the one or more first CG-SDT occasions. The UE may therefore transmit, to the base station, an uplink communication within the one or more first CG-SDT occasions or the one or more second CG-SDT occasions, using the radio resource allocation and the transmission scheme. 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 network node, a measurement configuration indicating one or more punctured resources of a physical downlink shared channel (PDSCH) that can be used for measurements associated with estimating an interference plus noise covariance (INC) matrix at the UE. The UE may receive, from the network node, a reporting configuration indicating one or more INC matrices at the UE to be reported. The UE may transmit, to the network node, a report indicating the one or more INC matrices at the UE based at least in part on receiving the reporting configuration. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. Generally, the described techniques provide for performing initial access procedures including transmitting or receiving synchronization signal blocks (SSBs) based on a capability of a user equipment (UE) to use reconfigurable intelligent surfaces (RISs). In some examples, a base station may transmit SSBs using two synchronization raster grids. For example, the base station may transmit SSBs on a first synchronization raster grid for UEs that do not support RISs and on a second synchronization raster grid for UEs that support RISs. In some examples, a base station may transmit different types of SSBs. For example, a base station may transmit a first type of SSB for UEs that do not support RISs and a second type of SSB for UEs that support RISs. A UE may search for and receive SSBs according to a capability of the UE.

Abstract: Certain aspects of the present disclosure provide techniques for repetition cancellation in full duplex communications. A method of wireless communication includes receiving scheduling information from a base station, wherein: the scheduling information schedules transmission of a plurality of uplink channel repetitions in a plurality of slots, the plurality of uplink channel repetitions is associated with a first sequence of redundancy versions (RVs), each repetition in the plurality of uplink channel repetitions assigned a different RV in the first sequence of RVs, and the plurality of slots include at least one full duplex slot comprising an uplink subband for uplink transmissions and a downlink subband for downlink transmissions; receiving an indication to cancel one or more repetitions of the plurality of uplink channel repetitions scheduled by the scheduling information; and taking one or more actions related to transmitting one or more remaining non-canceled repetitions of the plurality of UL channel repetitions.

Abstract: Methods, systems, and devices for wireless communications are described. In some wireless communications system, a base station may schedule multiple user equipment (UEs) for unicast transmissions using a single downlink control information (DCI) format. For example, a first UE may receive, from a base station, DCI that includes unicast scheduling information for multiple UEs including the first UE. The first UE may determine, from the unicast scheduling information, a set of resources on which to communicate data with the base station. In such cases, the UE may transmit or receive data transmissions using the determined set of resources. In some examples, each UE of the multiple UEs may determine respective sets of resources based on one or more UE-specific transformation rules applied to common scheduling parameters of the DCI.

Abstract: A second base station may allocate a set of downlink resources for a downlink transmission. The set of downlink resources may include a subset of null resources, which may serve as a signature for the second base station. The second base station may transmit downlink data or reference signals on the set of downlink resources including the subset of null resources. A first UE may experience the downlink transmission from the second base station as interference. The first UE may identify the set of downlink resources. The first UE may identify the subset of null resources. The first UE may transmit, to a first base station, an indication of the subset of null resources. The first base station may identify the second base station based on the indication of the subset of null resources. The first base station may transmit, to the second base station, an interference coordination message.
