Abstract: Methods, systems, and devices for wireless communications are described. A wireless repeater may communicate with multiple base stations, and the wireless repeater may identify a first base station as a primary base station. The wireless repeater may monitor for and receive control information from the primary base station, where the control information may include control information from a second base station and used by the wireless repeater to communicate with one or more UEs connected to the second base station. The primary base station may receive an indication of the control information from the second base station via a backhaul link. In other examples, the wireless repeater may monitor for control information from the two or more base stations based on a control signaling pattern. For example, the wireless repeater may be configured with periodic time intervals for monitoring for control signaling from respective base stations.

Abstract: Methods, systems, and devices for wireless communications are described. Aspects of the present disclosure provide techniques to achieve inter-base station beam management to avoid interference during full-duplex (FD) operations, half-duplex (HD) operations, flexible time-domain duplexing (TDD), or a combination thereof, by performing interference management specific to beam configurations. For example, a first base station (e.g., an aggressor base station operating in FD) may perform one or more actions to proactively determine if inter-base station interference may occur. In some cases, the aggressor base station may request measurements from one or more victim base stations. In other examples, the victim base station may request measurements from the aggressor base station. Additionally or alternatively, the victim base station may provide reactive feedback to the aggressor base station upon detecting interference.

Abstract: Techniques and apparatus for providing hybrid automatic repeat request (HARQ) feedback for multiple physical downlink shared channel (PDSCH) transmissions are described. One example technique involves receiving downlink control information (DCI) scheduling a plurality of downlink data transmissions across a plurality of slots. The plurality of downlink data transmissions are monitored across the plurality of slots. At least one HARQ feedback scheme for acknowledging the plurality of downlink data transmissions is determined. HARQ feedback for the plurality of downlink data transmissions is provided in accordance with the at least one HARQ feedback scheme.

Abstract: A network device is provided with excessive interference mitigation. In one implementation, the network device transmits a notification of the excessive interference to a network entity. In another implementation, the network device changes a receive beam or begins to acquire a new cell in response to a detection of the excessive interference. In yet another implementation, the network device alerts a user in response to a detection of the excessive interference.

Abstract: In an embodiment, a UE identifies a pool of resources where transmission of sidelink synchronization signals is permitted, the pool of resources including at least UE-specific resources, and transmits a sidelink synchronization signal to one or more peer sidelink UEs based on a subset of the pool of resources. In another embodiment, a UE transmits a synchronization request message to at least one peer sidelink UE, and receives at least one sidelink synchronization signal from the at least one peer sidelink UE in response to the transmission of the synchronization request message.

Abstract: Methods, systems, and devices for wireless communications are described. An assistive node may include circuitry for operating in an amplifying mode and operating in a reflecting mode. The assistive node may transmit a message to a network entity indicating that the assistive node is capable of operating in an amplifying mode or a reflecting mode. The network entity may transmit scheduling information to the assistive node for a packet transmission to be reflected or amplified by the assistive node to a wireless device, for example, because a direct path between the network entity and the wireless device is blocked. The network entity may transmit control signaling to the assistive node configuring the assistive node to either reflect or amplify the packet transmission to the wireless device. The assistive node may reflect or amplify the packet transmission to the wireless device based on the control signaling.
