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 also receives from the CU one or more resource conditions for using allocated resources of the semi-static resource allocation, and the first node communicates with a second node based on the semi-static resource allocation and the one or more resource conditions. 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: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a wireless node in a wireless multi-hop network may determine a change in multiplexing capability relating to communications on one or more radio link control (RLC) channels, and transmit information to a central unit that enables the central unit to cause modification of at least one of routing or RLC channel mapping in the wireless multi-hop network based at least in part on the change in multiplexing capability. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. A first wireless device may receive, from a second wireless device, a first downlink grant scheduling a first downlink resource for a delay-sensitive packet. The first wireless device may monitor the first downlink resource for the delay-sensitive packet from the second wireless device and identify a first routing identifier indicating at least a third wireless device in the first downlink grant. The first wireless device may transmit, to the third wireless device, a second downlink grant scheduling a second downlink resource and including a second routing identifier based on the first routing identifier. In some cases, the first wireless node may send a scheduling grant to the third wireless device for transmission of a delay-sensitive packet for a next hop before completion of processing of the packet received from the second wireless device.

Abstract: Methods, systems, and devices for wireless communications are described. A repeater may extend coverage of wireless communications services between two wireless nodes (e.g., a base station and a user equipment (UE)). A network control node (e.g., a base station) may receive a first indication of a capability of a repeater to detect a time division duplexing (TDD) pattern of a channel between the base station and the UE. The base station may transmit, to the UE and via the repeater, one or more parameters associated with the UE performing one or more channel measurements and reference signals for the channel measurements. The base station may transmit, to the repeater, a second indication of a TDD pattern of the channel based on the capability of the repeater. Based on the indication of the TDD pattern, the repeater may adjust one or more radio frequency components of the repeater.

Abstract: Methods, systems, and devices for wireless communication are described. A first device may receive a grant that schedules a wireless communication between the first device and a second device. The grant may indicate a demodulation reference signal (DMRS) configuration for a set of symbols associated with the wireless communication. The first device may receive control signaling that indicates a phase discontinuity associated with a first subset of symbols of the set of symbols. The first device may receive the wireless communication during a second subset of symbols of the set of symbols based on the DMRS configuration and the indication of the phase discontinuity. The first device may perform channel estimation based on receiving the wireless communication during the second subset of symbols.

Abstract: A method, apparatus, and computer-readable medium are provided that performs an interference measurement with an enhanced accuracy. The apparatus detects a signal from a serving cell, a neighbor cell, or a second apparatus in the neighbor cell. The apparatus estimates at least one of a downlink-downlink interference and a cross-uplink-downlink interference of the neighbor cell or the second apparatus in the neighbor cell. In another aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided that configures a User Equipment (UE) to perform the interference measurement and receives an interference measurement report from the UE. The apparatus estimates at least one of an uplink-uplink interference and a cross-downlink-uplink interference of the neighbor cell or the second apparatus in the neighbor cell.

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: 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.
