Abstract: Techniques for signaling uplink transmission configuration indicator (TCI) states are disclosed. In an example, a base station may determine one or more capabilities of a user equipment (UE). The base station may also determine one or more uplink TCI states for the UE to use based on the one or more capabilities. The base station may also transmit, to the UE, signaling of the one or more uplink TCI states.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a network node may communicate, using a first set of active antenna elements of an antenna array, during a first time period. The network node may activate a second set of active antenna elements based on a dynamic antenna set switching scheme, wherein the second set of active antenna elements includes at least one active antenna element not included in the first set, wherein a difference between a first main lobe property and a second main lobe property satisfies a main lobe threshold, and wherein a difference between a first side lobe property and a second side lobe property satisfies a side lobe threshold. The network node may communicate, using the second set of active antenna elements, during a second time period. Numerous other aspects are described.

Abstract: In an embodiment, a UE establishes, with a peer sidelink UE, at least one sidelink communications link that each comprises one or more hops. The UE determines estimates a propagation delay between the UE and the peer sidelink UE based in part upon a relationship between a propagation time, between the UE and the peer sidelink UE, and Reference Signal Received Power (RSRP) irrespective of whether the UE remains synchronized with respect to the network clock.

Abstract: Methods, systems, and devices for wireless communications are described. For example, the described techniques provide for wireless device (e.g., wireless repeater, wireless relay device, smart repeater, etc.) operation in a low power state, and base station signaling for triggering of wireless repeater control interface configuration. For example, a wireless repeater may operate in a power saving mode and monitor for control information from a base station according to a low power state or a slow state (e.g., according to a long monitoring periodicity relative to a monitoring periodicity associated with a full power state or fast state). Upon detection of triggering signal from a base station, the wireless repeater may transition to monitoring for control information from the base station according to a fast state (e.g., according to a short, or more frequent, monitoring periodicity relative to a monitoring periodicity associated with a low power state).

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, in a full duplex transmission mode, at least one downlink control information (DCI) transmission for scheduling an uplink communication and a downlink communication, wherein the at least one DCI transmission indicates a full duplex beam pair including a first beam associated with the uplink communication and a second beam associated with the downlink communication. The UE may communicate with at least one wireless communication device based at least in part on the uplink communication and the downlink communication. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a wireless node may communicate, with an integrated access and backhaul (IAB) donor, an indication associated with establishing a sidelink connection between the wireless node and an IAB node. The wireless node may receive, from the IAB donor, a configuration that maps a routing identifier to a route that includes the sidelink connection between the wireless node and the IAB node. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may identify a full-duplexing rule that indicates to refrain from using a transmission dropping rule for transmission direction conflicts that occur between uplink and downlink transmissions in a same symbol. The UE may receive a control message scheduling transmission of a message during a symbol, where a transmission direction conflict arises between a first transmission direction of the message and a second transmission direction of the symbol. For example, the UE may identify a transmission direction conflict between an uplink transmission direction of the message and a downlink transmission direction of the symbol. The UE may communicate the message during the symbol based on the full-duplexing rule. The described techniques may enable the UE to attain reduced latency and higher throughput based on reducing a number of transmissions dropped by the UE.

Abstract: Certain aspects of the present disclosure provide techniques for wireless communication by a user equipment (UE). For example, the UE receives a first indication indicating a same quasi co-location (QCL) mapping for multiple receive beams corresponding to a group of transmit and receive beam pairs from a network entity. Transmit and receive beam pairs are different from each other and grouping of the transmit and receive beam pairs is based on a distance between the UE and the network entity. The UE selects one of the multiple receive beams corresponding to the group of transmit and receive beam pairs, based on the distance between the UE and the network entity.
