Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a configuration for a transmission configuration state for receiving downlink channel transmissions from a base station via a configurable surface. The transmission configuration state may indicate a quasi-co-location source associated with transmission via the configurable surface. The UE may receive a downlink channel transmission via the configurable surface based on the transmission configuration state and the quasi-co-location source. The UE may be capable of determining whether the transmission configuration state conflicts with the quasi-co-location source indicated by the transmission configuration state. The UE may transmit an indication to the base station that the configuration for the transmission configuration state conflicts with the quasi-co-location source. The indication may include a beam failure indication or a measurement report. The UE may fall back to a transmission configuration state previously activated at the UE.

Abstract: Aspects presented herein may enable an RF sensing node to transmit RF sensing signals based on OFDM symbols that may be flexibly configured, such that OFDM symbols used for RF sensing may be different from OFDM symbols used for communications. In one aspect, an RF sensing node transmits an RF sensing signal in a first time duration of a symbol in an RF sensing session. The RF sensing node monitors for a reflected RS sensing signal in a second time duration of the symbol that does not overlap with the first time duration, the symbol including a CP that does not overlap with the first time duration and the second time duration.

Abstract: Techniques for channel state feedback using sensing reference signals are disclosed. The techniques can include identifying a channel state information (CSI) report configuration based on CSI reporting configuration information received from a radio access network (RAN) node of a RAN, based on the CSI report configuration, identifying a set of basis reference signals to be measured on a wireless channel of the RAN, wherein the set of basis reference signals includes one or more sensing reference signals, measuring the set of basis reference signals to obtain channel state measurements, determining channel state information based on the channel state measurements, and transmitting a CSI report including the channel state information to the RAN node.

Abstract: A victim user equipment (UE) may experience cross-link interference (CLI) from transmissions from an aggressor UE. The present disclosure provides for configuration of a CLI report that accurately characterizes the CLI experienced by the victim UE. A base station may transmit to the victim UE, a configuration for CLI reporting associated with one or more channel state information interference measurement (CSI-IM) resources. The victim UE may generate a CLI report based on the configuration for CLI reporting and the CSI-IM resources. The victim UE may transmit the CLI report to the base station. The base station may use the CLI report to mitigate the CLI, for example, by scheduling the aggressor UE and the victim UE to reduce CLI experienced by the victim UE.

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: Certain aspects of the present disclosure provide a method of wireless communication at a network entity, comprising transmitting, in different time periods, different subsets of a set of synchronization signal blocks (SSBs), wherein SSBs within a subset are transmitted using frequency division multiplexing and applying different spatial filtering to different SSBs of a subset transmitted in a same time period.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a controller of a reconfigurable reflective surface may receive or determine configuration information for a set of reflective elements of the reconfigurable reflective surface, wherein the configuration information indicates a set of reflective matrices associated with indicating reconfigurable reflective surface information to a user equipment (UE), wherein the configuration information indicates the UE, and wherein the configuration information is associated with reflecting a signal in a sub-band, of multiple sub-bands, of a base station. The controller may configure the set of reflective elements to indicate the reconfigurable reflective surface information via the signal as reflected by the reconfigurable reflective surface. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. A reconfigurable reflective surface may exploit signals transmitted from a user equipment (UE) to communicate feedback to a base station. For example, the surface may communicate feedback by reflecting two or more reference signals according to two or more configurations. In some cases, the two or more configurations may be phase shifted relative each other. In another example, the surface may communicate feedback by altering the intensity of or more reference signals transmitted from the UE. In yet another example, the surface may communicate feedback to the base station by reflecting reference signals towards one or more antenna arrays. In some cases, the one or more antenna arrays may be located at a single base station. In some other cases, the one or more antenna arrays may be located at multiple base stations or multiple transmission/reception points.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a user equipment (UE) may receive, from a serving base station, a first round-trip time (RTT) measurement signal. The UE may send, to the serving base station, a second RTT measurement signal. The UE may send, to at least one other UE, a third RTT measurement signal. The UE may send, to the serving base station or to a location server, an indication of a first delay between receiving the first RTT measurement signal and sending the second RTT measurement signal and an indication of a second delay between sending the second RTT measurement signal and sending the third RTT measurement signal.
