Abstract: Methods, systems, and devices for wireless communications are described. Techniques described herein support transmission of a transport block over multiple slots (TBoMS) with subband full duplex (SBFD) operation. For example, if a time domain resource allocation for a TBoMS includes both uplink slots and downlink slots configured with an uplink subband, a user equipment (UE) may determine which slots to use in accordance with a scheme for selecting available slots for the TBoMS from indicated candidate slots, and the UE may determine the transport block size based on the selected slots. In some examples, the UE may first determine the quantity of resource elements available in each of the different slot types, and then may determine the transport block size based on the quantity of resource elements available in each of the different slot types and the quantity of each of the different slot types.

Abstract: Systems, methods, and devices for wireless communication that support cell-group slot format indication (SFI) facilitating dynamic cross-cell operation are described. Cell-group SFI information of some examples supports full duplex operation implemented using cross-cell communication techniques. Devices may be provided with information regarding cell-groups and information regarding cell slot formats for cells in the cell-groups. For example, cell-group SFI may be provided for switching slot (symbol) types across cells for a number of slots, wherein a base station may define a cell-group and a cell-group SFI applies to cells within the cell-group. Cell-group SFI information may indicate cell slot formats for each cell of a selected cell-group to provide a device with slot formats used with respect to the cells of the cell-group. Other aspects and features are also claimed and described.

For example, the UE may receive an indication that a time interval is associated with the operating state of the network node. The UE may identify an operating state associated with a current time interval and may apply a corresponding TCI state that is associated with the operating state.

Abstract: Methods, systems, and devices for wireless communications are described. A transmitter may select a precoder from a codebook for precoding one or more signals for transmission to a receiver. The transmitter may select the precoder from the codebook based on antenna configurations at the transmitter and the receiver. The precoder may be constructed using one or more Slepian sequences. In some implementations, the Slepian sequences may be associated with a quantity of transmit antennas at the transmitter. For instance, a length of each Slepian sequence may correspond to (for example, be equal to) a quantity of transmit antennas at the transmitter. Further, the Slepian sequences may be associated with a bandwidth within which to concentrate the one or more signals. Once the transmitter selects the precoder, the transmitter may precode the one or more signals and transmit the precoded signals to the receiver.
