Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first user equipment (UE) may receive, from a network node, an indication of first level shared information, that is shared between at least the first UE and a second UE, for deriving a security key from common sidelink information. The first UE may determine second level shared information, that is shared between the first UE and the second UE, for deriving the security key from the common sidelink information. The first UE may communicate with the second UE using the security key derived from the common sidelink information based at least in part on the first level shared information and the second level shared information. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. Random access channel (RACH) occasions may be scheduled on each component carrier (CC) of a carrier aggregation (CA) configuration that includes both a time division duplexing (TDD) TD Raid band and at least one frequency division duplexing (FDD) band based on a synchronization signal/physical broadcast channel block (SSB) received in the TDD band. In some cases, the TDD band may be used to configure the RACH occasions in same and/or different CCs. Additionally or alternatively, the FDD band may configure the RACH occasions on its uplink CC based on SSBs received on other CCs. Additionally, the RACH occasions may be configured such that the UE avoids unavailable uplink slots when transmitting a first RACH message in a RACH occasion.

Abstract: Aspects relate to measuring downlink beam quality in the presence of self-interference when operating in a full duplex mode configured for concurrent transmission and reception within an overlapping bandwidth. A user equipment (UE) may communicate with a base station over one or more of a plurality of uplink beams and downlink beams. For each uplink beam, the UE may obtain beam quality measurements associated with each of the downlink beams to identify a set of usable downlink beams. The UE may further transmit a report to the base station indicating the set of usable downlink beams for at least one uplink beam.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may identify one or more quality metrics associated with one or more respective control channel elements (CCEs) of a first set of candidate resources that partially overlaps with a second set of candidate resources, wherein the first set of candidate resources is associated with a first aggregation level and the second set of candidate resources is associated with a second aggregation level. The UE may prune the second set of candidate resources based at least in part on a shaping pattern of the one or more quality metrics satisfying a quality tolerance threshold. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a network node may receive information indicating a reservation or allocation of a resource for transmission of a first signal by another network node, wherein the information identifies whether the network node is to use the resource for transmission of a second signal concurrently with the first signal. The network node may transmit the second signal in the resource based at least in part on the information identifying whether the network node is to use the resource for transmission of the second signal. Numerous other aspects are described.

Abstract: This disclosure provides methods, components, devices and systems for discovery signaling for seamless roaming. Some aspects more specifically relate to indicating or advertising information associated with a single mobility domain (SMD) and information associated with access point (AP) devices that support seamless roaming. In some implementations, an AP device or a multi-link device (MLD) may transmit parameters associated with the SMD MLD to advertise information of the SMD MLD. In some implementations, the AP device or MLD may advertise candidate AP devices, which may support the seamless roaming. A non-MLD device, such as a wireless station (STA), may request additional information for a candidate AP device that supports seamless roaming. The AP device may transmit a response to the request indicating a portion of a profile of the candidate AP device.
