Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive an indication of a span pattern for a super slot that corresponds to a transmission time interval over multiple slots. The UE may monitor, within a span that is specified by the span pattern and that extends across a slot boundary in the super slot, physical downlink control channel candidates for downlink control information. Numerous other aspects are described.

Abstract: Aspects of the present disclosure are regarding cross-link interference (CLI) measurements for received signal strength indicator (RSSI) based positioning. An example method for wireless communication performed by a first user equipment (UE), comprising: receiving, from a base station, a first message comprising a cross-link interference (CLI) configuration; performing one or more CLI measurements associated with an uplink transmission of a second UE based on the CLI configuration; receiving a second message comprising an uplink transmission power measurement of the second UE; determining a pathloss associated with the second UE based on the one or more CLI measurements and the uplink transmission power measurement; and determining a range between a location of the first UE and a location of the second UE based on the pathloss.

Abstract: Methods, systems, and devices for wireless communications are described. A first user equipment (UE) may receive, from a base station, a configuration indicating an interference reciprocity between the first UE and a second UE, where the interference reciprocity is associated with cross link interference (CLI) between the first UE and the second UE. The first UE may also receive, from the base station, an indication of a transmit power of the second UE. The first UE may measure a pathloss associated with the CLI between the first UE and the second UE based at least in part on the received transmit power of the second UE. The first UE may determine a transmit power for transmission of one or more uplink messages based at least in part on the measured pathloss and transmit the uplink messaged using the determined transmit power.

Abstract: Disclosed are techniques for environment sensing by an electronic device, such as a user equipment (UE) or base station. In an aspect, the electronic device uses a radio frequency (RF) signal configured to transmit information on orthogonal frequency division multiplexing (OFDM) symbols in accordance with a wireless communication standard, such as Fifth Generation (5G) New Radio (NR), for environment sensing. The electronic device configures one or more transmission parameters for the RF signal based on one or more factors related to a resolution to be provided by the RF signal, a type of application for which the environment sensing RF signal is being transmitted, capabilities of the UE, and the like. The electronic device then transmits the environment sensing RF signal, over an uplink, downlink, or sidelink, as appropriate to the type of electronic device, in accordance with the one or more transmission parameters.

Abstract: Certain aspects of the present disclosure provide techniques for efficient signaling of frequency resources in multiple cells. For example, a single downlink control information (DCI) transmission to a user equipment (UE) may be used to indicate a bandwidth part (BWP) switch to be applied in multiple cells. In some cases, the BWP switch may be into a pre-defined BWP across the multiple cells (and the same DCI may also schedule or trigger data or reference signals in the pre-defined BWP).

Abstract: User Equipment (UE) receives, from a base station (BS), at least one resource block (RB). The RB includes at least one reference signal (RS) resource element (RE) of a first physical channel of the UE. The UE estimates a channel quality of a second physical channel of the UE as a function of the at least one RS RE. In some examples, the BS associates the transmission of a first physical channel reference signal (RS) and the transmission of a second physical channel RS. The BS then signals, BS to the UE, the association between the first physical channel reference signal and the second physical channel reference signal.
