Abstract: Certain aspects of the present disclosure provide techniques for inter-slot and intra-slot frequency hopping in full duplex. A method performed by a user equipment (UE) includes receiving scheduling information from a network entity, wherein the scheduling information schedules transmission of a plurality of uplink data channel repetitions in a plurality of slots according to a frequency hopping scheme that configures frequency hops between transmissions of repetitions of the plurality of uplink data channel repetitions. The method also includes taking one or more actions related to transmitting, according to the frequency hopping scheme, the plurality of uplink data channel repetitions in the plurality of slots based on the scheduling information.

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 downlink control information (DCI) that schedules an uplink communication in an uplink frequency band. The UE may transmit, at an uplink frequency within the uplink frequency band, the uplink communication with a power that varies over the uplink frequency band based at least in part on a location of the uplink frequency relative to a downlink frequency band associated with the UE. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may be receive a grant configuration including multiple set of parameters, and the UE may select a set of parameters from the configured grant based on a channel condition. In some examples, the UE may be configured to signal to a network (e.g., a base station) the selected set of parameters and their corresponding parameter values. For example, the UE may be configured to signal the selected set of parameters over semi-static signaling (e.g., radio resource control (RRC) messaging) or dynamic signaling (e.g., medium access control-control element (MAC-CE) messaging, uplink control information (UCI) messaging, or the like). By configuring the UE with multiple set of parameters, the UE may adapt to changing channel conditions, which may provide higher reliability and lower latency for wireless communications, as well as reduce power consumption for the UE.

Abstract: Aspects are provided which allow a UE to provide a CSI report including an expiration time to a base station to reduce the risk of improper scheduling decisions at the base station based on outdated CSI reports. The UE obtains a channel measurement signal from the base station. The UE identifies CSI based on the channel measurement signal and provides a CSI report to the base station including the CSI. The CSI report further includes an expiration time for the CSI report. The base station obtains the CSI report from the UE including the expiration time for the CSI report, and the base station processes downlink data for transmission based on the expiration time in the CSI report.

Abstract: Aspects are provided which allow for multiplexing of higher priority uplink transmissions with lower priority uplink transmissions while maintaining URLLC of the higher priority uplink transmission. A UE receives from a base station information including resources for first and second uplink data, where at least a portion of the resources for the first and second uplink data overlap in time. The first and second uplink data are associated with different priority levels. The UE determines whether to multiplex the uplink data based on a transmission timing difference between a scheduled transmission time and a multiplexed transmission time for the second uplink data on the respective resources. The base station makes a similar determination. If the transmission timing difference fails to meet a delay threshold, multiplexing is performed; otherwise, the lower priority transmission is dropped. Thus, different priority multiplexing may occur in low latency situations, satisfying URLLC.

Abstract: A UE may identify slots to transmit and/or receive information related to one or more HARQ processes in frame structure that includes both sub-band full duplex slot types and time division duplex slot types. Based on a first slot used for control information, a UE can identify a second slot for PUSCH or PDSCH communication based on an offset between the first slot and the second determined by calculating slot offsets (e.g., based on parameters received from a base station). In some aspects, a UE may exclude certain slot duplex types (e.g., SBFD or TDD) when calculating slot offsets. In some aspects, a UE may calculate slot offsets differently for different HARQ processes corresponding to one frame. In some aspects, slot offset behaviors may be based on priority of information associated with a HARQ process.

Abstract: Aspects of the disclosure relate to a reconfigurable intelligent surface (RIS) controller for controlling a RIS panel to be frequency and/or element dependent, and for operating an adaptive filtering function. The RIS controller may be configured to transmit, to a scheduling entity, a RIS frequency capability indication for indicating communication support of the RIS panel for one or more frequency ranges. The scheduling entity, then, may transmit RIS control information based on the RIS frequency capability indication. In response, the RIS controller may receive the RIS control information and configure the RIS panel based on the RIS control information. Other aspects, embodiments, and features are also claimed and described.

Abstract: Aspects of the disclosure relate to multiple-input and multiple-output (MIMO) codebook configuration for wireless downlink communications. A user equipment or a scheduled entity receives a reference signal (channel state information reference signal (CSI-RS) and transmits a CSI report based on the reference signal. The CSI report includes a rank indicator configured to indicate one or more ranks among multiple ranks corresponding to multiple antenna panels associated with the reference signal, and a precoding matrix indicator (PMI) corresponding to a codebook for the plurality of antenna panels. In some examples, a first rank of the multiple ranks is different from a second rank of the plurality of ranks. In other examples, a first antenna panel of the multiple antenna panels having a different number of antenna ports than a second antenna panel of the multiple antenna panels. Other aspects, embodiments, and features are also claimed and described.
