Abstract: A first wireless device transmits one or more transmissions for a second wireless device to a repeater for repetition to the second wireless device; adjusts a repeater operation based on a phase noise in transmission between the first wireless device and the repeater; and communicates with at least one of the repeater or the second wireless device based on the adjusted repeater operation. A repeater receives from a first wireless device, a request for the repeater to report a phase noise in transmissions between the first wireless device and the repeater for repetition with a second wireless device; and transmits a report of the phase noise to the first wireless device based on the request. A repeater receives, from a first wireless device, a transmission for repetition with a second wireless device; and transmits the repetition of the transmission to the second wireless device with a phase noise compensation.

Abstract: Aspects of the disclosure provide techniques and apparatuses for using keep-alive signaling for network energy saving in an idle mode. A network entity can transmit a keep-alive signal (KAS) to reduce the energy consumption of a network when the network is in an idle mode. In some aspects, the KAS can be a reduced synchronization signal block (SSB) that is sent more frequently than a full SSB. In some aspects, the KAS can have a different beam sweeping pattern and/or beam width from the full SSB.

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: 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.

Abstract: Certain aspects of the present disclosure provide techniques for acquiring location information of an assisting node, such as an assisting transmission and reception point (TRP). The location information may include geographical location information as well as spatial information. The location information may be used to facilitate positioning and other purposes, such as beam management, interference management, and sensing between one or more assisting TRPs and one or more network entities (e.g., a gNodeB (gNB), a user equipment (UE), a central unit (CU), or a distributed unit (DU)). To achieve these purposes, accurate locations of the assisting TRPs are needed. The present disclosure provides techniques for acquiring and exchanging the accurate location information of such assisting TRPs.

In some aspects, an integrated access and backhaul (IAB)-donor central unit (CU) may trigger connectivity between a distributed unit (DU) of a first network node and the IAB-donor CU, wherein the first network node comprises an IAB-node. The IAB may instantiate connectivity between a mobile terminal (MT) of the first network node and the IAB-donor CU after instantiation of the connectivity between the DU of the first network node and the IAB-donor CU. The IAB may transmit a communication to a second network node via the first network node. Numerous other aspects are described.
