Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may receive a control message indicating a channel state information (CSI) reporting configuration for a subband full-duplex (SBFD) slot. The CSI reporting configuration may indicate that the UE is to report CSI for entire bandwidths of respective downlink subbands of the SBFD slot. That is, the CSI reporting configuration may configure the UE for per-downlink subband CSI reporting. The UE may receive CSI reference signals via the downlink subbands, and measure CSI for the reference signals. The UE may transmit, according to the CSI reporting configuration, a CSI report indicating the CSI for the downlink subbands. In some examples, the CSI may include some combination of channel quality indicators (CQIs) and precoding matrix indicators (PMIs).

Abstract: Disclosed are techniques for wireless communication. In an aspect, a user equipment (UE) receives positioning reference signal (PRS) resources of a PRS instance, receives at least one symbol of a high priority downlink channel scheduled during a PRS processing window for the PRS instance, wherein the high priority downlink channel is determined to have high priority based on the high priority downlink channel being associated with a high priority uplink channel, and refrains from processing the PRS resources of the PRS instance during the PRS processing window based on one or more conditions related to prioritizing PRS processing, wherein the one or more conditions indicate that the UE does not expect to process the PRS resources of the PRS instance during the PRS processing window based on the at least one symbol of the high priority downlink channel being scheduled during the PRS processing window.

Abstract: Methods, systems, and devices for wireless communications are described in which a user equipment (UE) may be configured with periodic uplink grants that provide a number of repetitions and a redundancy version (RV) sequence for the repetitions. Prior to the start of an uplink grant period, the UE may determine a set of slots that are available for uplink transmissions in the uplink grant period. Based on the set of slots, the UE may determine a corresponding RV for repetitions of the uplink communication associated with each slot. The slots with uplink transmissions within the uplink grant period may be non-contiguous. Repetitions of an uplink communication may be configured to be transmitted across multiple uplink grant periods, which may be triggered based on a threshold value associated with the repetitions.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) switch between carriers of a group of a carriers during uplink communications in accordance with a mapping. For example, the UE may report its capability to a base station for switching between carriers of the group, where the group includes a supplementary uplink (SUL) carrier and two or more normal uplink (NUL) carriers that are each associated with a different radio frequency band. The base station may indicate for the UE to switch to a subset of carriers of the group corresponding to a combination of radio frequency bands for transmission of an uplink message. The UE may switch to at least one carrier of the subset of carriers in accordance with a mapping that is based on the reported capability and may transmit the uplink message on the at least one carrier.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may perform, in accordance with a synchronization raster, a cell search in a channel having a transmission bandwidth that is less than or equal to 5 MHz, wherein the synchronization raster is based at least in part on the transmission bandwidth. The UE may detect, based at least in part on the cell search, a synchronization signal block (SSB). Numerous other aspects are described.

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.

Abstract: Wireless communications systems and methods related to downlink (DL) control channel communications are provided. A wireless communication device identifies a search space set including a plurality of PDCCH candidate search spaces for a downlink control channel. The wireless communication device determines that a first resource associated with a first PDCCH candidate search space of the plurality of PDCCH candidate search spaces overlaps with a preconfigured resource. The wireless communication device monitors for a downlink control message over the downlink control channel by excluding monitoring in at least the first PDCCH candidate search space based on the determining.
