Abstract: Certain aspects of the present disclosure provide techniques for dynamically scheduling antenna resources of a wireless node, such as, antenna panels of a user equipment (UE). In some cases, a first node (e.g., a UE) performs, with two or more other nodes, a first beam sweep procedure across two or more antenna resources of the first node on two or more wireless interfaces, generates or obtains scheduling information based on results of the first beam sweep procedure, wherein the scheduling information indicates which of the antenna resources is scheduled for which wireless interfaces, and communicates with the other nodes on the wireless interfaces according to the scheduling information.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a child node of a parent node in an integrated access backhaul (IAB) network may determine communication information that includes one or more of a schedule or a configuration for a communication to be transmitted by the child node. The child node may be an IAB node, and the parent node may be an IAB donor or an intervening IAB node between the IAB node and an IAB donor. The child node may transmit the communication information to the parent node via a wireless backhaul link between the child node and the parent node. Numerous other aspects are provided.

Abstract: Certain aspects of the present disclosure provide techniques for increasing diversity of transmissions with slot aggregation using slot-specific cyclic delay diversity (CDD). A method that may be performed by a transmitting device includes determining to transmit a signal using cyclic delay diversity (CDD) in a plurality of slots; and transmitting the signal using a different cyclic delay in each slot of the plurality of slots.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a parent node may determine that a set of resources is not available for the parent node for communication with a child node of the parent node. The parent node may provide an availability indicator to the child node based at least in part on determining that the set of resources is not available for the parent node for communication with the child node. The availability indicator may indicate the set of resources as available for the child node. Numerous other aspects are provided.

Abstract: This disclosure provides methods, devices and systems for beamforming in wireless communications. Some implementations more specifically relate to beamforming configurations for multicast communications. A transmitting device may transmit multicast data to multiple receiving devices, concurrently, via a physical downlink shared channel (PDSCH). The PDSCH may be preceded by a physical downlink control channel (PDCCH). The PDCCH may provide scheduling information for the PDSCH, including a multicast beam associated with the PDSCH and a timing offset or delay between the PDCCH and the PDSCH. A receiving device may determine that the PDSCH contains multicast data based on an indication in the PDCCH. To receive the PDSCH, each receiving device may tune its antennas in a direction of the scheduled multicast beam or a default beam based on the delay between the PDCCH and the PDSCH.

Abstract: The present disclosure relates to methods and devices for wireless communication at a wireless device or integrated access and backhaul (IAB) node. In one aspect, the wireless device may determine a frequency synchronization accuracy for the wireless device. The wireless device may also transmit an indication of the determined frequency synchronization accuracy for the wireless device. Additionally, the wireless device may determine an absolute frequency based on a combination of measurements from at least one synchronization source and a frequency of the wireless device, where the frequency synchronization accuracy is based on the absolute frequency.

Abstract: Systems, apparatuses, and methods for enhancement for amplify-and-forward relay. Instead of merely passing received signal from a source, relay may equalize the received signal based on reference signal contained in the received signal, before amplifying and transmitting the signal to a destination. Compared to amplify-and-forward, equalize-and-forward may compensate the received source signal for various imperfections such as channel distortions and phase errors, using demodulation reference signal and phase tracking reference signal. The relay may apply Fast Fourier Transform (FFT) to equalize the signal in tone domain.

Abstract: Certain aspects of the present disclosure provide techniques for group semi-persistent scheduling (SPS) for path diversity. A method that may be performed by a node includes configuring one or more groups of user equipments (UEs) with one or more SPS resources. The node sends a downlink control information (DCI) to activate one of the SPS resources for one of the groups of UEs and transmits data to the group of UEs using the activated SPS resource. A first UE may receive data from the node using the activated SPS resource and retransmit the data to the second UE. The first helping UE and the second targeted UE may be identified based on the higher layer configuration with the SPS resources, based on information in the DCI, and/or based on information sent with the data.
