Abstract: Disclosed are techniques for wireless communication. In an aspect, a user equipment receives a positioning reference signal (PRS) configuration for at least one or more PRS resources, wherein at least one parameter of the PRS configuration is encrypted using at least one secret key to provide an encrypted value of the at least one parameter in the PRS configuration, receives the at least one secret key, and applies the at least one secret key to the at least one parameter to recover an original value of the at least one parameter.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first device may generate a request for energy from a second device that is capable of charging the first device in association with energy harvesting. The first device may generate an indication that indicates a maximum duration for which the request applies. The first device may transmit the request and the indication to the second device. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described that support signaling for energy harvesting at a first device. In some examples, the first device may transmit, to a second device, an indication of one or more an energy conversion efficiency factors, power threshold parameters, power levels, battery power levels, or the like. Based on receiving the indication of the one or more of the characteristics, the second device may determine a radio frequency power for subsequent signaling. The second device may transmit a signal having the determined radio frequency power, and the first device may receive the signaling and convert at least a first portion of the radio frequency power to direct current (DC) power.

Abstract: Methods, systems, and devices for wireless communications are described. A network entity may configure a mapping between a set of power states and a set of codepoints. The network entity may indicate the mapping to a user equipment (UE) via control signaling, such as a first control message. Each power state may correspond to a respective directional communication profile associated with the network entity, the UE, or both. The network entity may transmit a second control message to the UE to indicate a codepoint from the set of codepoints. The UE device may transition to a power state that corresponds to the codepoint (e.g., based on the mapping) in accordance with the second control message. In some examples, the network entity may indicate the codepoint in a field of the second control message associated with a search space set group (SSSG) switching indication.

Abstract: Disclosed are techniques for wireless positioning. In an aspect, a network node transmits, to a network entity, a request for transmission of one or more first positioning reference signals (PRS) resources having one or more physical layer security properties, and measures the one or more first PRS resources having the one or more physical layer security properties. In an aspect, a network entity receives, from a first network node, a request for transmission of one or more first positioning reference signals (PRS) resources having one or more physical layer security properties, and transmits, to a second network node, a request for the second network node to transmit the one or more first PRS resources having the one or more physical layer security properties to the first network node.

Abstract: The apparatus may be configured to receive a first indication of a CFR associated with at least one of an MCCH or an MTCH for a plurality of RedCap UEs in one of an inactive or idle state supporting a first capability having a first maximum bandwidth that is different from a second capability having a second maximum bandwidth that is greater than the first maximum bandwidth. The apparatus may also be configured to monitor the CFR indicated in the first indication for at least one of broadcast traffic or multicast traffic. The apparatus may be configured to output, for transmission to the plurality of RedCap UEs, the first indication and output, for transmission to the plurality of RedCap UEs, at least one of an MCCH communication or an MTCH communication via the CFR indicated in the first indication for at least one of broadcast traffic or multicast traffic.

Abstract: Methods, systems, and devices for wireless communications are described. A first wireless device may transmit, to a second wireless device, a message indicating a capability of the first wireless device to support full-duplex line-of-sight (LOS) multiple-input multiple-output (MIMO) communications. The first wireless device may receive, from the second wireless device, control signaling indicating an uplink channel resource allocated for one or more uplink communications, a downlink channel resource allocated for one or more downlink communications, a first set of LOS MIMO transmission modes for the one or more uplink communications, and a second set of LOS MIMO transmission modes for the one or more downlink communications. The uplink channel resource may at least partially overlap with the downlink channel resource in time, frequency, or both. The first wireless device may communicate the one or more uplink communications and the one or more downlink communications based on the control signaling.
