Abstract: Methods, systems, and devices for wireless communications are described. Generally, the described techniques provide for identification of a slot format for a set of slots where at least one slot format of the set is an subband full-duplex slot (e.g., includes uplink and downlink resources separated in a frequency domain). The base station may transmit one or more semi-persistent scheduling configurations to a UE. The UE may identify semi-persistent scheduling occasions for receiving a downlink communication based at least in part on the SPS configurations matching the format of the slot, the periodicity of the slot formats of the set, or other considerations. The UE and the base station may communicate based at least in part on the determined semi-persistent scheduling occasions.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may identify an opportunistic conversion of a particular resource from a downlink resource into an uplink or full-duplex resource. The UE may determine at least one parameter for the particular resource based at least in part on identifying the opportunistic conversion of the particular resource from the downlink resource into the uplink or full-duplex resource, wherein the at least one parameter includes at least one of a power control parameter, a bandwidth part configuration, a configured grant configuration, or a random access configuration. The UE may communicate, using the particular resource, in accordance with the at least one parameter. Numerous other aspects are described.

Abstract: The apparatus, in some aspects may be a UE configured to communicate, in a FD mode, with at least one base station. The UE may further be configured to determine, when communicating with the at least one base station in the FD mode, FD UE assistance information including one or more FD UE assistance parameters. The UE may also be configured to transmit, to the at least one base station, an indication of the determined FD UE assistance information including the one or more FD UE assistance parameters. In some aspects, the apparatus may be a base station configured to communicate with at least one UE operating in a FD mode. The base station may further be configured to receive, from the at least one UE, an indication of FD UE assistance information including one or more FD UE assistance parameters.

Abstract: Aspects of the present disclosure relate to wireless communication. In some aspects, a user equipment (UE) may receive a configuration that indicates an association between a sounding reference signal (SRS) resource set and a downlink reference signal resource to be used to determine a transmission property of one or more SRSs in the SRS resource set, wherein the downlink reference signal resource is associated with a first set of ports to be used for performing measurement of the downlink reference signal resource. The UE may determine the transmission property of the one or more SRSs in the SRS resource set using fewer ports than a number of ports included in the first set of ports, based at least in part on a determination that the UE is operating in a power saving mode. The UE may transmit the one or more SRSs using the transmission property. Other aspects are provided.

Abstract: Systems and methods in which one or more wireless communication stations implement duplex-mode remediation to facilitate the signal communication when an issue with respect to self-interference is identified are described. Duplex-mode remediation may be implemented for various communication scenarios, such as for random access phase communications, for communications having different priorities, etc. A wireless communication station may implement one or more changes with respect to the full duplex operation of the wireless communication station based upon determining that an issue with respect to self-interference may be, or is being, experienced, such as to provide for a wireless communication station operating in an in-band full duplex mode to increase interference cancellation and/or to fall back to a sub-band full duplex mode or a half duplex mode, to provide for a wireless communication station operating in a sub-band full duplex mode to increase interference cancellation and/or to fall back to a half duplex mode.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may be configured to estimate a signal-to-noise ratio for each antenna port associated with a reception of one or more tracking reference signals. The UE may receive one or more of multiple single-port tracking reference signals, a single multi-port tracking reference signal, or a tracking reference signal associated with multiple power ratios. The UE may be able to estimate a channel upon receiving a demodulation reference signal. The channel estimation may be based on the reception of one or more of multiple single-port tracking reference signals, the single multi-port tracking reference signal, or the tracking reference signal associated with multiple power ratios. The UE may communicate with the base station based on estimating the channel.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive scheduling information that schedules a physical downlink shared channel (PDSCH) communication for the UE; and select a downlink beam for reception of the PDSCH communication from a set of usable downlink beams associated with an uplink beam to be used by the UE for uplink transmission in one or more symbols in which the PDSCH communication is scheduled. Numerous other aspects are provided.

Abstract: Certain aspects of the present disclosure provide techniques for managing scheduling of wireless communications. A method that may be performed by a user equipment (UE) includes receiving, from a base station, one or more configurations indicating a plurality of minimum scheduling offset values; receiving, from the base station, a signal indicating one of the minimum scheduling offset values as an updated value to be used for communications with the base station and a type of scheduling; determining a delay based on the type of scheduling; and after the reception of the signal, using the updated value for communications with the base station based on the determined delay.

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.

Abstract: Certain aspects of the present disclosure provide techniques for wireless communication scheduling. An example method that may be performed by a user equipment (UE) includes receiving, from a base station, one or more configurations indicating wireless communication resources including at least one of a plurality of bandwidth parts (BWP) or a plurality of component carriers (CCs); receiving, from the base station, control signaling indicating a scheduling offset to communicate with the base station via at last one of the BWPs within at least one of the CCs; determining a value of the scheduling offset based at least in part on a minimum scheduling offset value; and taking at least one action in response to the determination.
