Abstract: The apparatus may be a base station. The apparatus processes a first group of synchronization signals. The apparatus processes a second group of synchronization signals. The apparatus performs a first transmission by transmitting the processed first group of the synchronization signals in a first synchronization subframe. The apparatus performs a second transmission by transmitting the processed second group of the synchronization signals in a second synchronization subframe.

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. A base station may manage a shape of a beam to selectively reduce interference at one or more wireless nodes. The base station may receive a capability message from a first wireless node indicating a capability of the first wireless node to support one or more beam tapering configurations. In some cases, the base station may receive an interference report from a second wireless node, indicating that the first wireless node caused interference at the second wireless node. The base station may transmit a beam tapering configuration of the one or more beam tapering configurations to the first wireless node, and the first wireless node may transmit a beamformed message to the base station according to the beam tapering configuration. In some cases, the beam tapering configuration may be associated with less interference when transmitting the beamformed message.

Abstract: Methods, systems, and devices for wireless communications are described. In some examples, a base station may identify one or more communication paths to a user equipment (UE), and may determine an end-to-end signal quality for each communication path (e.g., a signal-to-noise ratio (SNR)), one or more hop SNR values for each hop of each communication path, a ratio of the hop SNR values and the end-to-end SNR of each communication path, or a combination thereof. Based on the determined SNR values, ratios, or both, the base station may select a first communication path for a first type of communications (e.g., uplink, downlink, signal type, or the like) and a second communication path for a second type of communications (e.g., uplink, downlink, signal type, or the like), and may communicate with the UE using the selected communication paths.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first wireless communication device (WCD) may transmit, to a second WCD, information for selecting transmission or reception directions for a first beam and a second beam for communications between the first WCD and the second WCD using a full duplex operation. The WCD may receive an indication to use, for the full duplex operation of the first WCD, the first beam to receive communications and the second beam to transmit communications. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communication are described. A communication device, for example, a user equipment (UE) may select a default beam to use for downlink communication while operating in a full duplex mode. The UE may receive from another communication device, for example, a base station control signaling indicating the default beam for the UE to use for the downlink communication. A default beam (which may also be referred to as a full duplex beam) may be a default downlink beam or a default uplink beam. In some examples, the UE may select a default beam pair to use for downlink communication and uplink communication while operating in the full duplex mode. A default beam pair (which may also be referred to as a full duplex beam pair) may include both a default downlink beam and a default uplink beam.

Abstract: In an aspect, the present disclosure includes a method, apparatus, and non-transitory computer readable medium for wireless communications for a donor node to provide a resource pattern over an integrated access and backhaul (IAB) backhaul. The aspect may include determining, at a central unit (CU) of the donor node, a configuration of a resource pattern for a plurality of IAB-nodes of an IAB network, wherein the configuration of the resource pattern includes a base resource pattern configured with a base periodicity of one or more slots and a plurality of distributed unit (DU) slot format indices within the base periodicity. The aspect may include transmitting, by the CU of the donor node, the resource pattern to one or more of the plurality of IAB-nodes of the IAB network.

Abstract: A network node (e.g., base station, user equipment (UE)) in a wireless communication network may not be aware of the presence and/or availability of assisting nodes deployed in a wireless communication network to assist the network node. The aspects described herein include a method of wireless communication for an apparatus (e.g., an assisting node). The apparatus transmits an availability signal to enable discovery of the apparatus and indicate an availability of the apparatus to assist at least one network node. The availability signal includes an identifier of the apparatus. The apparatus relays at least one wireless communication between the at least one network node and a network entity.
