Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a base station may determine, for full-duplex mode communication on a first link and a second link, a timing adjustment to at least one of a first timing or a second timing, wherein the timing adjustment is to cause a delay between clutter reflection from a first signal and an occurrence of a second signal to occur during a cyclic prefix of the second signal; cause the timing adjustment to be applied to the at least one of the first timing or the second timing; and communicate in the full-duplex mode with a first node and a second node in accordance with the timing adjustment, wherein communicating includes transmitting the first signal to the first node and receiving the second signal from the second node. Numerous other aspects are provided.

Abstract: In an aspect, a network device (e.g., BS, core network component, etc.) determines a self-interference measurement (SIM) configuration associated with null-forming at a wireless device (e.g., UE or BS), the null-forming associated with steering at least one receive beam of the wireless device and/or at least one transmit beam of the wireless device away from one or more external sources of self-interference. The network device transmits the SIM configuration to the wireless device. The wireless device performs at least one null-forming procedure in accordance with the SIM configuration.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a wireless node may receive, from a control node, information identifying a slot configuration pattern for a wireless communication link between the wireless node and another wireless node. For example, the information identifying the slot configuration pattern may indicate one or more symbols that are configured to support full-duplex communication. The wireless node may communicate with the other wireless node in the one or more symbols configured to support full-duplex communication in accordance with the slot configuration pattern. Numerous other aspects are provided.

Abstract: Aspects described herein relate to determining, by a node, to establish a first connection with a first upstream node for receiving downlink communications, and determining, by the node, to establish a second connection with a second upstream node for transmitting uplink communications or establishing a second connection with the same upstream node based on a second transmit/receive beam pair. The first connection can be established with the first upstream node based on a first transmit/receive beam pair. The second connection can be established with the second upstream node (or the same upstream node) based on a second transmit/receive beam pair and concurrently with the first connection is established with the first upstream node.

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: A configuration for local coordination between the child node and parent node to enable SDM communication between the parent and child node, without input or interaction from the CU. The apparatus receives, from a CU, an indication including an allocation of resources. The apparatus determines a type of communication with a second node based on the allocation of resources. The apparatus communicates with the second node based on the determined type of communication and utilizing the allocated resources. The apparatus coordinates with a parent node to utilize the allocated resources in a SDM operation between the child node and the parent node.

Abstract: A transmit/receive switching circuit implementation reduces transmitting/receiving switching losses in a transceiver during different modes of operation. The implementation includes connecting a low noise amplifier and a power amplifier in accordance with a shunt configuration in the transceiver. The implementation also includes disabling the power amplifier to achieve a high impedance state by grounding an output stage bias and enabling the low noise amplifier and disabling one or more transistors connected to a path between the low noise amplifier and the power amplifier during a receive mode.
