Abstract: Certain aspects of the present disclosure provide techniques for configuring timing advances for uplink communications resources. A method for wireless communications by a user equipment includes receiving, from a base station, signaling that configures a first timing advance and a second timing advance. The first timing advance is configured to be used by the user equipment when transmitting an uplink communication in a half-duplex resource, and the second timing advance is configured to be used by the user equipment when transmitting an uplink communication in a full-duplex resource. The method may further include transmitting, to the base station, a first uplink communication within a first resource using one of the first timing advance or the second timing advance based on whether the first resource comprises a half-duplex resource or a full duplex resource.

Abstract: Aspects relate to a base station configured to transmit a message to a sidelink (SL)-repeater, configuring the SL-repeater to transmit sidelink synchronization signal blocks (S-SSBs) including S-SSB index numbers, receive a SL-node identification and a preferred S-SSB index number, and transmit the SL-node identification and the preferred S-SSB index number to the SL-repeater. The base station may be configured to transmit a first message configuring a SL-repeater to broadcast a sidelink discovery message, receive a sidelink discovery report from the SL-repeater identifying discovered SL-node(s), and transmit a second message activating the SL-repeater for sidelink communication with the SL-node(s). Another aspect relates to a SL-repeater configured to: transmit a sidelink discovery message, receive first response(s) from respectively responding SL-node(s), and transmit a report to a base station identifying a change in membership between a first list of the respectively responding SL-node(s) and a second list of previously responding SL-nodes.

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: Aspects of the present disclosure provide techniques for sidelink repeating operations, such as by using an assisting node (e.g., a smart repeater, relay, or reflector) to enhance sidelink communication reliability. For example, one or more assisting nodes may be configured by a network entity and repeat sidelink communications for two or more user equipments (UEs). In aspects, an assisting node may receive, from the network entity, an indication of resources available for sidelink communications between a first UE and a second UE. The assisting node may also receive signaling that configures the assisting node to repeat sidelink communications between the first and the second UEs over the indicated resources. The assisting node then repeats sidelink communications between the first and the second UEs according to the received signaling.
