Abstract: Aspects presented herein may enable an entity that is receiving (or reading) reflected/backscattered signals from an IoT device to differentiate the reflected/backscattered signals from other reflections (e.g., noise or signals bounced from other objects). In one aspect, a wireless device transmits an indication of a positioning session to an IoT device, wherein the indication initiates the positioning session for the IoT device. The wireless device transmits, based on the positioning session, a set of PRSs to the IoT device via a plurality of transmission occasions. The wireless device receives, from the IoT device based on a reflection pattern, at least one PRS in the set of PRSs via at least one reception occasion.

Abstract: Certain aspects of the present disclosure provide techniques for channel access. One example method by a wireless node generally includes selecting a mode of operation associated with a configuration for communicating with one or more other wireless nodes, determining a procedure for gaining access to a medium to be used for the communication, wherein the procedure is determined based on the mode of operation, and communicating with the one or more other wireless nodes using the mode of operation after gaining access to the medium based on the procedure.

Abstract: Methods, systems, and devices for wireless communications are described. A communication device, which may be otherwise known as user equipment (UE) may receive a downlink control information (DCI) on a physical downlink control channel (PDCCH). The DCI may include one or more of an indication of a set of transmission configuration indicator (TCI) states related to a physical downlink shared channel (PDSCH), one or more receive beams associated with the set of TCI states, or a physical downlink shared channel (PDSCH) scheme. The UE may decode the DCI and may determine a temporal period associated with the indication of the set of TCI states. The UE may receive, based on the temporal period, the PDSCH according to one or more of the set of TCI states, the one or more receive beams associated with the set of TCI states, the PDSCH scheme, or one or more default receive beams.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may transmit, to a base station, a capability report that includes an indication of a maximum number of reference signal resources within a transmission time interval (TTI) for which the UE supports channel state information (CSI) reporting. The maximum number of reference signal resources may be based on a capability for supporting joint CSI reporting for both a downlink and an uplink. The UE may receive, from the base station, a report configuration in response to the capability report. Subsequently, the base station may transmit reference signals to the UE, which the UE may use to determine CSI for both the downlink and the uplink. The UE may then transmit, to the base station, a CSI report including the CSI for both the downlink and the uplink, in accordance with the report configuration.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a transmitting (Tx) node may perform a channel measurement in a channel sensing contention slot based at least in part on a measurement time, wherein the measurement time is based at least in part on one or more of a sensing bandwidth or a beam switching time. The Tx may perform, to a receiving (Rx) node, a transmission based at least in part on a value of the channel measurement satisfying a threshold. Numerous other aspects are described.

Abstract: Wireless communication methods and devices for selective receiver-assisted channel sensing are provided. In some aspects, one or more receivers (e.g., UEs) can be selectively configured to perform receiver-assisted channel sensing (e.g., class A channel sensing) using at least one of trigger signaling and channel sensing configuration by a BS, UE capabilities, or operational mode. For example, a method for wireless communication performed by a user equipment (UE) includes: sensing a channel based on at least one of a receiver-assisted channel sensing trigger, or a UE capability; and transmitting, to a base station (BS) based on the sensing, channel sensing information.

Abstract: Wireless communications systems and methods related to channel occupancy time (COT) sharing for sidelink communications are provided. A first user equipment (UE) receives, from a second UE, a first sidelink transmission during a first channel occupancy time (COT), where the first COT is associated with the second UE. The first UE determines whether the second UE is one of two or more UEs intended to receive a second sidelink transmission. The first UE transmits, to the two or more UEs, the second sidelink transmission during a portion of the first COT based on COT sharing. The COT sharing is in response to determining the second UE is one of the two or more UEs intended to receive the second sidelink transmission.
