Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit, to a node, a request for a security key for sidelink connectionless groupcast communication that is performed without a radio resource control connection between UEs. The request may indicate a distance from the UE for using the security key. The UE may receive, from the node, information that indicates the security key. Numerous other aspects are described.

Abstract: Methods, apparatuses, and computer-readable medium for fronthaul compression are provided. An example method may include receiving, from a UE, uplink data via one or more active tones of a plurality of tones in a symbol, the uplink data corresponding to an access vector. The example method may further include compressing the uplink data based on a linear transformation of a pseudo-access vector generated based on the access vector, the linear transformation including a matrix, the compression enabling a second network entity to decompress the compressed uplink data without knowing one or more locations associated with the one or more active tones. The example method may further include transmitting, to the second network entity, the compressed uplink data.

The method generally includes performing one or more measurements of one or more reflections of the RF sensing signal. Certain aspects of the subject matter described in this disclosure canbe implemented in a method for wireless communication by a BS. The method generally includes receiving a RF sensing capabilities message from a UE. The method generally includes transmitting, to the UE, a configuration for the UE to perform RF sensing based on the RF sensing capabilities message.

Abstract: A node may forward, from a base station to a first UE, or from the first UE to the base station, one or more wireless signals. The node may identify an indication to stop signal forwarding to the first UE. The indication may be based on a level of an interference to a second UE associated with the signal forwarding to the first UE being greater than a first threshold. The level of the interference to the second UE may be based on a path gain difference or a signal strength at the first UE associated with the signal forwarding to the first UE. The signal strength at the first UE associated with the signal forwarding to the first UE may correspond to an RSRP at the first UE. The node may stop the signal forwarding to the first UE based on the indication.

Abstract: A node may identify a node configuration including one or more surface phase configurations associated with the node. In one configuration, the node may receive, from the base station, an indication of the node configuration. In another configuration, the node may select, at a controller associated with the node, the node configuration. The one or more surface phase configurations may be based on a wavelength corresponding to a center of a BWP associated with the one or more wireless signals or a wavelength corresponding to a center of a resource allocation associated with the one or more wireless signals. The node may forward, from a base station to a UE, or from the UE to the base station, one or more wireless signals. The forwarded one or more wireless signals may be associated with a beam squint less than a first threshold.

Abstract: This disclosure provides systems, devices, apparatus, and methods, including computer programs encoded on storage media, for assisted mmW sidelink beam discovery in non-standalone mode. A UE may transmit, to an AN, a request to access one or more ADs. The request may be based on an absence of at least one BPL that has a threshold QoS for a DRB with a second UE. The UE may receive, from the AN based on the transmitted request, an authorization to access the one or more ADs, and exchange, via an SRB, beam training information with the second UE based on the authorization to access the one or more ADs for performing a beam training procedure via the one or more ADs.

Abstract: Certain aspects of the present disclosure provide techniques for wireless communications by a user equipment (UE) including receiving a first reference signal (RS) from a first transmission reception point (TRP); receiving a second RS from a second TRP, wherein the first TRP and the second TRP are both associated with a BS; and transmitting, to the BS, an indication that one of a first shifted carrier frequency at which the first RS is received or a second shifted carrier frequency at which the second RS is received is preferred for use by the UE as a reference carrier frequency for demodulation.

Abstract: Aspects of the present disclosure provide techniques for dynamically adjusting the access link timing alignment at the integrated access and backhaul (IAB) node. Specifically, features of the present disclosure provide techniques for signaling to one or more child nodes the timing advance and timing offset values associated with each operational mode of the TAB node that may impact the access link timing for the child node (for uplink and/or downlink transmissions). Additionally or alternatively, aspects of the present disclosure identify whether a gap period may be included in order to ensure that the child node has sufficient time to transition between states during the transition period (e.g., from downlink to uplink) when the TAB node dynamically adjusts the access link timing.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a wireless node may communicate, using a first antenna panel, a first reference signal (RS) based at least in part on a first RS configuration, and communicate, simultaneously with the first RS and using a second antenna panel that is different than the first antenna panel, a second RS based at least in part on a second RS configuration, wherein the second RS configuration orthogonalizes the second RS relative to the first RS. Numerous other aspects are provided.
