Abstract: Methods, systems, and devices for wireless communications are described. To reduce peak-to-average power ratio (PAPR) associated with transmissions in a wireless communications system, a user equipment (UE) may implement tone reservation techniques. The UE may receive downlink control information from a base station that indicates a set of allocated resources that the UE is to use for the tone reservation. The UE may identify a first set of tones of the set of allocated resources for transmitting a data signal and a second set of tones of the set of allocated resources for transmitting a peak-reduction signal that reduces the peak power of the data signal. The UE may transmit the data signal and the peak-reduction signal based on the received downlink control information.

Abstract: Methods, systems, and devices for wireless communication are described. Generally, the described techniques provide for a user equipment (UE) to receive a message including transmission configuration indicator (TCI) states information associated with beam information for uplink or downlink resources. The UE may identify multiple channels or reference signals, or both, to which a TCI state is to be applied based on associated indications included with the TCI state information. In some examples, the TCI state information may also include indications of source reference signals for quasi co-location (QCL) assumptions for the indicated channels or reference signals. Based on applying the TCI state, the UE may determine beam information for uplink or downlink resources and may communicate with the base station accordingly.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) in an optical wireless communications system may utilize a curved focal plane of a condenser lens to communicate an optical wireless signal. An optical front-end (OFE) of the UE may include one or more optical communication components located at varying distances from the condenser lens on a curved focal plane of the condenser lens. Additionally or alternatively, the UE may adjust a position of one or more optical communication components on the curved focal plane. Additionally or alternatively, the OFE may include an array of condenser lenses and optical communication components each optically coupled with one or more condenser lenses. The UE may perform equal gain combination and/or equal ratio power splitting to communicate an optical wireless signal using the array of condenser lenses and optical communication components.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit a first indication of a multiple-input-multiple-output (MIMO) configuration threshold that is associated with a selection between a polarization MIMO configuration and a spatial MIMO configuration, the MIMO configuration threshold being based at least in part on a performance threshold. The UE may receive a second indication of a MIMO communication configuration that specifies the selection. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, via medium access control (MAC) signaling, an indication to activate one or more transmission configuration indicator (TCI) states for the UE, wherein the indication triggers at least one of a measurement of a reference signal or a transmission of a measurement report for at least one TCI state of the one or more TCI states, wherein the reference signal or the transmission of the measurement report is triggered based on an association of a TCI state with the reference signal or the measurement report. The UE may receive the reference signal based on receiving the indication to activate the one or more TCI states. The UE may transmit the measurement report based on the indication triggering the transmission of the measurement report. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described that provide for resource allocation in an integrated access and backhaul (IAB) network. A relay node in an IAB network may be assigned a first resource partition that is different from a second resource partition for the child and parent nodes. Based on a resource configuration (e.g., for a slot) of the second resource partition, the relay node may opportunistically utilize the second resource partition for communications. For instance, the relay node may determine a direction table based on the resource configurations of the child and parent nodes, which may be used to perform uplink or downlink communications in one or more symbols of the second resource partition. The relay node may also identify flexible symbols as free or non-free when determining the direction table.
