Abstract: The present disclosure provides systems, devices, apparatus and methods, including computer programs encoded on storage media, for an autonomous fallback for a full-duplex beam pair. In a first aspect, a first wireless device may determine an occurrence of a performance trigger for a current beam pair for full-duplex communication at the first wireless device and use a fallback full-duplex beam pair in response to determining the occurrence of the performance trigger. In a second aspect, the first wireless device may receive an indication from a second wireless device of an occurrence of the performance trigger for the current beam pair for full-duplex communication and using the fallback full-duplex beam pair for communication with the second wireless device in response to receiving the indication.

Abstract: Aspects of the present disclosure provide techniques for configuring multi-beam full-duplex communication that allows a device (e.g., user equipment (UE) or base station) to contemporaneously perform both uplink and downlink communication over the same frequency band. Because of the full duplex communication capability provided by the present disclosure, the NR system may achieve reduced latency and improved spectrum and resource efficiency, thereby accommodating a growing demands for the wireless communication. The full duplex communication capability may be achieved by implementing downlink control information (DCI) format that specifies to the UE the beam assignments for contemporaneous transmission (Tx) and reception (Rx). Particularly, beams may be selected such that the beam(s) assigned for communication are independent and uncorrelated, and therefore provide sufficient beam diversity in order to mitigate the limitations of current systems, including self-interference that has hindered implementation of full duplex communication in current systems.

Abstract: Methods, systems, and devices for wireless communications are described. Techniques described herein relate to schemes for managing an overlap of at least part of a tracking reference signal (TRS) with an uplink subband or a guard band in a subband full duplex (SBFD) slot or symbol. In some examples, if a user equipment (UE) and/or a network entity determines that at least a portion of a TRS is scheduled for reception in an uplink subband or a guard band of an SBFD slot or symbol, the UE and/or the network entity may: drop the TRS, puncture the portion of the TRS that overlaps with the uplink subband or the guard band; or may shift the frequency position of the TRS such that the TRS is scheduled within the downlink subband(s) of the SBFD slot or symbol.

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: Methods, systems, and devices for wireless communications are described. For instance, a network entity may transmit, to a user equipment Transmission (UE), control signaling indicating that the UE is to provide feedback corresponding to a set of feedback process identifiers for at least one component carrier. The network entity may transmit, to the UE, a cancellation indication Feedback Message that cancels a scheduled uplink transmission in which the UE is scheduled to provide feedback data corresponding to a subset of the set of feedback process identifiers. The network entity may transmit, to the UE, a control message scheduling the UE to transmit the feedback data corresponding to the subset of the set of feedback process identifiers (e.g., based on the cancellation indication). The UE may transmit, to the network entity, a feedback message including the feedback data for the subset based on the control message.

Abstract: Methods, systems, and devices for wireless communications are described. A first device may cooperate with a second device to form a virtual device configured to communicate with a radio access network. The virtual device may appear as a single device from the perspective of the radio access network. Subsequently, a third device may be identified for replacing the second device within the virtual device. Based on the third device being identified, procedures for handing over communications from the second device to the third device may be executed. The procedures may include a beam management procedure, a random-access procedure, a mobility management procedure, or any combination thereof.

Abstract: The present disclosure provides for a configuration that enables an apparatus to determine beam pairs for full duplex communication based on a cross-link interference procedure. The apparatus determines a subset of receive beams based on a beam measurement process, where each receive beam is associated with a different antenna array panel. In some aspects, the apparatus performs a channel measurement process based on the subset of receive beams. The apparatus sweeps through transmitted sounding reference signals from a same transmit beam corresponding to each receive beam of an antenna array panel and receives the transmitted sounding reference signals incrementally through other receive beams associated with other antenna array panels. The apparatus measures a self-interference for at least one beam pair of the subset of receive beams based on a received sounding reference signal. The apparatus selects one or more beam pairs based on a self-interference measurement or a signal-to-interference-plus-noise ratio.

Abstract: Aspects of the disclosure relate to a user equipment (UE) that receives a timing advance command from a network access node, sends a value indicative of a timing advance capability to the network access node, adjusts a timing advance indicated by the timing advance command based on the timing advance capability to yield an adjusted timing advance, and transmits an uplink signal to the network access node using the adjusted timing advance. Further aspects relate to a network access node that transmits a timing advance command to a user equipment (UE), receives a value indicative of a timing advance capability of the UE, and receives an uplink signal adjusted by a timing advance according to the timing advance capability of the UE. The timing advance capability may indicate that the UE has, or does not have, a capability to adjust the timing advance indicated by the timing advance command.

Abstract: Methods, systems, and devices for wireless communications are described. A first user equipment (UE) may receive a control message indicating a set of interference measurement resources (IMRs) for reference signal transmission associated with radio link monitoring or beam failure monitoring. The first UE may receive, from a second UE via the set of IMRs, reference signals associated with radio link monitoring or beam failure monitoring based on the control message. The first UE may transmit, in response to receiving the reference signals, a beam failure report associated with the radio link monitoring or the beam failure monitoring based on one or more measurements of the one or more reference signals. In some examples, the beam failure report may indicate that beam failure is associated with cross-link interference (CLI) from the second UE.
