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.

Abstract: Methods, systems, and devices for wireless communications are described. In some cases, a user equipment (UE) may transmit, to a base station, a report indicating a capability of the UE to support symbol level quantization, slot level quantization, or both. The UE may identify that the UE is to utilize the slot level quantization For instance, the UE may receive control signaling indicating that the UE is to utilize slot level quantization and may perform the identifying based on receiving the control signaling The UE may receive a first transmission via a first channel and may communicate, responsive to receiving the first transmission, a second transmission via a second channel at a quantized start timing determined in accordance with the slot level quantization.

Abstract: Certain aspects of the present disclosure provide techniques for downlink and/or uplink beam management for full-duplex communications. An example method generally includes receiving, from a wireless node, a RS resource configuration indicating interference RS resources associated with interference reference signal transmissions; monitoring interference RSs via the interference RS resources; for each of the interference RS resources, determining a reception beam based at least in part on the monitored more interference RSs corresponding to the interference RS resources; receiving control signaling, from the second wireless node, indicating QCL information, which also indicates to either refrain from using any monitored interference RS resource in determining spatial reception parameters or identify at least one monitored interference RS resource to use in determining the spatial reception parameters; and determining the spatial reception parameters in accordance with the control signaling.

Abstract: Aspects are provided which allow a user equipment (UE) to identify a low-bandwidth (low-BW) CORESET-0 and associated CSS based on reception bandwidth of the UE. The base station may configure different frequency and time-domain resources of the low-BW CORESET in order to optimize resource utilization of the low-BW CORESET-0, and the low-tier UE may identify these resources of CORESET-0 and CSS from the system configuration information received in a master information block (MIB). As a result, low tier UEs may operate in a same cell as legacy UEs without the need for the base station to transmit additional signaling to either legacy UEs or lower tier UEs for the UEs to receive their respective CORESET-0's and identify a physical downlink channel (PDCCH).
