Abstract: Methods, systems, and devices for wireless communications are described. A frequency band configuration for a full-duplex slot may be indicated, where a frequency band configuration may include one or more downlink frequency bands and one or more uplink frequency bands. In some cases, a frequency band configuration may also include one or more guard bands. A user equipment (UE) may determine the frequency band configuration for a full-duplex slot based on a frequency configuration indication, which may include an index for a table of frequency band configurations, one or more bitmaps, or respective start and length indications for each frequency band. A frequency band configuration may apply to one slot or to multiple slots.

Abstract: This disclosure provides methods, devices, and systems for physical uplink shared channel (PUSCH) repetition based on support signaling, such as an uplink grant that includes a time domain resource assignment for transmitting one or more data repetitions that may cross a slot boundary. The UE may identify directions (for example, uplink, downlink, flexible) for one or more symbols spanning a transmission duration of the time domain resource assignment. The directions may be determined using a dynamic slot format indication (SFI), or semi-static SFIs may be used as a fallback (when dynamic slot format indications do not meet a target reliability). The uplink grant may include an indication of which symbol directions can be used for the one or more data repetitions. A subset of the one or more symbols for scheduling the one or more data repetitions may be determined based on the identified directions.

Abstract: A base station is disclosed that includes two separated antenna arrays. In a TDD mode of operation, both arrays are used for either transmit or receive. In a sub-band full-duplex mode of operation, one array is used to transmit downlink symbols while the remaining array is used to receive uplink symbols.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may perform a measurement operation to attain multiple measurements to report to a base station. The measurements may correspond to a first number of bits if reported. The UE may compress the measurements using an encoder neural network (NN) to obtain an encoder output indicating the measurements. This encoder output may include a second number of bits that is less than the first number of bits. The UE may report the encoder output to the base station in this compressed form. At the base station, the encoder output may be decompressed according to a decoder NN. Once the base station decompresses the encoder output, the UE and base station may communicate according to the measurements determined from the decompression. In some cases, the base station may perform load redistribution based on the measurements.

Abstract: Certain aspects of the present disclosure provide techniques for fast adaptation of transmission properties of sounding reference signal (SRS) resource sets. A method that may be performed by a user equipment (UE) includes receiving sounding reference signal (SRS) configuration information, configuring the UE with one or more SRS resource sets, wherein each of the one or more SRS resource sets comprises one or more SRS resources; receiving signaling comprising a field indicating which of the one or more SRS resources in the one or more SRS resource sets are active and which of the one or more SRS resources in the one or more SRS resources sets are inactive; and transmitting one or more SRSs using only the one or more SRS resources that are active.

Abstract: Methods, systems, and devices for wireless communications are described for indicating modulation order and code rate for transmissions between a user equipment (UE) and a base station. The base station may configure one or more parameter tables that provide mapping between a modulation and coding scheme (MCS) index and the modulation order and code rate. The one or more tables may be explicitly indicated in configuration signaling, may be configured based on a frequency range for communications or a reference signal configuration, or any combinations thereof. The base station may transmit control information to the UE that indicates the MCS index value and that indicates a first table of multiple configured tables is to be used to determine the modulation order and code rate.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, from a base station, signaling indicating a channel state information (CSI) report configuration. The CSI report configuration may indicate a mapping between one or more CSI reference signal (CSI-RS) resources or one or more CSI-RS port groups and one or more antenna panels or antenna subpanels of the base station. The UE may generate CSI feedback based on the mapping. In some cases, the UE may generate the CSI feedback based on multiple hypotheses that correspond to CSI-RS measurements. In some examples, the multiple hypotheses may include a set of hypothesis groups based on one or more antenna panels or antenna subpanels of the base station. The UE may transmit a message reporting the CSI feedback to the base station.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive signaling that configures a downlink bandwidth for a broadcast channel transmission (e.g., a physical downlink control channel transmission). The UE may determine a bandwidth of the capability is less than the downlink bandwidth, and monitor search space occasions in a period to receive samples of the broadcast channel. The period and the search space occasions may be associated with a control resource set and a search space set. The UE may receive the samples in non-overlapping subbands of the bandwidth according to the bandwidth capability, and detect the broadcast channel based on the samples. The UE may additionally monitor repeated transmission occasions in the period based on detecting the broadcast channel to detect a second broadcast channel (e.g., a physical downlink shared channel).
