Abstract: Bi-static radio-based object location detection can include determining, by a wireless device, a location of a remote wireless device; obtaining a ToF and an angle of arrival (AoA) of a reflected WWAN reference signal reflected by a remote object; and determining a location of the remote object based on the location of the remote wireless device, the ToF, and the AoA. In another example, a wireless device includes a wireless transceiver; a non-transitory computer-readable medium; and a processor communicatively coupled to the wireless transceiver and non-transitory computer-readable medium, the processor configured to determine a location of a remote wireless device; obtain a ToF and an angle of arrival (AoA) of a reflected WWAN reference signal reflected by a remote object; and determine a location of the remote object based on the location of the remote wireless device, the ToF, and the AoA.

Abstract: Aspects of the present disclosure relate to wireless communications, and more particularly, to mobility techniques that allow for mobility of a user equipment (UE) between a set of cells. A method that may be performed by a UE includes receiving signaling configuring the UE with a set of cells that support physical (PHY) layer or medium access control (MAC) layer mobility signaling and with a measurement configuration for the set of cells, reporting, to a network entity, measurements for at least some of the set of cells in accordance with the measurement configuration, and receiving, from the network entity, PHY layer or MAC layer mobility signaling to move the UE to one of the cells in the set, wherein the mobility signaling is based, at least in part, on the reported measurements.

Abstract: Frequency-dependent changes in beam shapes of transmitted RF signals can be provided to a receiving device. Beam shape information can include, for example, gain of a beam and a plurality of azimuth and elevation directions, boresight and width of a main lobe (and optionally side lobes) of the beam, information regarding a pattern of antenna elements of an antenna panel used to transmit the beam, and/or similar information. The type of information provided can dictate the amount of overhead required, and we therefore vary depending on the means by which the information is conveyed. Additional detail is provided in the embodiments described herein.

Abstract: Wireless communications systems and methods related to dynamically configuring sounding reference signal (SRS) resources are provided. In some aspects, a base station may measure a SRS transmission transmitted by a user equipment (UE) and receive, using a receive beam selected based on the measuring, a transmission from the UE. In some aspects, a UE may transmit a SRS transmission; and receive, from the BS, a downlink control information (DCI) message including a SRS resource indicator (SRI) for use by the UE in selecting a beam to transmit to the BS. The SRS transmission may be transmitted using a SRS resource and may have a SRS parameter that is indicated in or related to a triggering message, or related to a transmission parameter of a communication between the BS and the UE.

Abstract: A user equipment (UE) and base station may be configured to implementing trigger-based joint TX-RX sensing for channel access. In some aspects, the UE may monitor, via a receiver, for one or more transmissions from a first base station, detect, during the monitoring, interference associated with a pre-grant communication, the pre-grant communication associated with a future communication between a second base station a second user equipment, and transmit, via a transmitter, a reservation communication to the second base station in response to the pre-grant communication. In some aspects, the UE may receive the one or more communications from the first base station, without interference from the second base station, based on transmitting the reservation communication.

Abstract: In one aspect of the disclosure, a UE may be configured to receive, from a base station, information indicating a reference point associated with at least one L1 measurement; determine a reporting value of the at least one L1 measurement based on a difference between the reference point and a measured value of the at least one L1 measurement; and transmit information indicating the reporting value to the base station. In another aspect, a RAN node can indicate to a UE that a reduced measurement report resolution is to be used for beam measurements in a measurement report. The reduced measurement report resolution is less than a first measurement report resolution previously indicated to be used for the beam measurements. Lower resolution can be obtained by using fewer bits to indicate one or more of the beam measurements. The payload for a measurement report such as a L-SINR or L-RSP L1 measurement report is thereby reduced when the UE transmits the measurement report to the RAN node.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, in a single dynamic signaling communication, an indication to activate one or more coverage enhancement parameters. The UE may activate the one or more coverage enhancement parameters based at least in part on receiving the indication. Numerous other aspects are provided.

Abstract: In cross-carrier scheduling of DCIs on a data channel, a base station may transmit a first DCI on a first radio frequency (RF) carrier, where the first DCI schedules a data channel of a second RF carrier (and optionally indicates that the base station will transmit at least one DCI on the data channel of the second RF carrier). In some examples, the base station may transmit the first DCI in a control channel of the first RF carrier. In some examples, the base station may transmit the first DCI in a data channel of the first RF carrier. In some examples, the base station may transmit, in a data channel of the second RF carrier, a second DCI that indicates that the base station will transmit at least one DCI in the data channel of the first RF carrier.
