Abstract: In an embodiment, a UE establishes, with a peer sidelink UE, at least one sidelink communications link that each comprises one or more hops. The UE determines estimates a propagation delay between the UE and the peer sidelink UE based in part upon a relationship between a propagation time, between the UE and the peer sidelink UE, and Reference Signal Received Power (RSRP) irrespective of whether the UE remains synchronized with respect to the network clock.

Abstract: Aspects of the present disclosure are regarding configuring an Integrated Access and Backhaul (IAB) node of an IAB network to handle forwarding of packets from another device as well as packets originating in the IAB network at the IAB-node. An example method includes retrieving, by a Backhaul Adaptation Protocol (BAP) layer of the IAB-node, a packet from an upper layer or a Radio Link Control (RLC) layer of the IAB-node. The method also includes determining an egress RLC channel of an egress backhaul (BH) link with a second device for transmitting the first packet based on a first configuration in response to retrieving the first packet from the RLC layer or a second configuration in response to retrieving the first packet from the upper layer. The method also includes transmitting the first packet to the second device via the egress RLC channel of the egress BH.

Abstract: Aspects relate to a physical cell identifier (PCI) change within a wireless network based on a primary synchronization signal (PSS) waveform. A scheduling entity, such as an integrated-access-backhaul (IAB) node within a radio access network (RAN), may communicate with a set of one or more scheduled entities, such as other IAB nodes and/or user equipment (UEs), utilizing a first PCI. The scheduling entity may then change from the first PCI to a second PCI, where the second PCI corresponds to a different PSS waveform than the first PCI. In some examples, the scheduling entity may change the PCI as a result of a PCI collision and/or PSS collision with a neighboring scheduling entity.

Abstract: Aspects of the present disclosure provide apparatus, methods, processing systems, and computer readable mediums to enhance the functionality of directional repeaters (wireless devices that relay directional wireless signals). For example, by adding even limited capability to buffer digital samples, repeater functionality may be enhanced to provide better coverage and make more efficient use of time, frequency, and spatial resources. An example method generally includes receiving, from a base station, a configuration indicating how the wireless device is to process stored digital samples of a first radio frequency (RF) signal, receiving the first RF signal, wherein the receiving comprises generating the digital samples of the first RF signal, storing the digital samples, and processing the stored digital samples according to the configuration.

Abstract: The present disclosure relates to methods and apparatus for wireless communication of a first node. The apparatus can receive a first signal from a second node of one or more additional nodes, the first signal including at least one first timing reference. The apparatus can also determine a second timing reference quality of a second timing reference. The apparatus can also transmit a second signal to at least one node of the one or more additional nodes, the second signal including a second timing reference. Additionally, the apparatus can broadcast, to the one or more additional nodes, an indication of a second timing reference quality of the second timing reference. The apparatus can also receive an indication of a first timing reference quality. Moreover, the apparatus can adjust the indication of the quality of the at least one timing first reference from the second node.

Abstract: Certain aspects of the present disclosure provide techniques for use of SS transmitted using a UE-specific configuration of time-frequency resources. A BS may assign at least one UE-specific configuration, wherein the UE-specific configuration comprises an allocation of resources for a UE-specific SS for mobility management purposes. The BS may communicate with the UE based, at least in part, on the UE-specific configuration. A UE may correspondingly receive the UE-specific configuration and communicate with a BS based, at least in part, on the configuration.

Abstract: The systems and methods described herein support efficient SDM operation in IAB networks. A first node receives a semi-static resource allocation from a CU based on at least one multiplexing capability of the first node. The first node communicates with a second node based on the semi-static resource allocation. The first node also transmits a change request to the CU to modify the semi-static resource allocation, and the first node may communicate with the second node based on the modified semi-static resource allocation. The at least one multiplexing capability includes at least one of SDM or FDM, including full duplex or half duplex. The at least one multiplexing capability is also with respect to one or more transmission direction combinations of the first node.

Abstract: The systems and methods described herein support efficient SDM operation in IAB networks. A first node transmits a report to a CU, where the report includes at least one multiplexing capability or condition of the first node. The first node receives a semi-static resource allocation from the CU based on the at least one multiplexing capability, and the first node communicates with a second node based on the semi-static resource allocation. The at least one multiplexing capability includes at least one of SDM or FDM, including full duplex or half duplex. The at least one multiplexing capability is also with respect to one or more transmission direction combinations of the first node.
