    Abstract: Methods, systems, and devices for wireless communications are described. A communication device, which may be known as user equipment (UE), may be capable of full-duplex communications. The UE may determine that at least a portion of a downlink transmission that the UE may receive while concurrently scheduled to transmit an uplink transmission, may overlap with a clear channel assessment (CCA) procedure (e.g., a listen-before-talk (LBT) operation) in a shared radio frequency spectrum band. The UE may determine that at least a portion of the downlink transmission that overlaps with the LBT resources may be canceled or the downlink transmission may be rate matched and allocated to resources outside of the LBT resources. As a result, the UE may perform an LBT procedure without interference caused by the UE receiving the downlink transmission.

    Abstract: Systems, devices, and methods associated with interference aware sounding reference signals are provided. A method for wireless communication includes receiving, at a wireless communication device in communication with a first base station, an interfering signal from a second base station (or others); determining, at the wireless communication device, a spatial direction of the interfering signal; and transmitting, with the wireless communication device, a signal to the first base station based on the spatial direction of the interfering signal. Another method includes receiving, at a first base station, a signal from a wireless communication device, the signal based on a spatial direction of an interfering signal received by the wireless communication device from a second base station (or others); transmitting, with the first base station, a downlink communication to the wireless communication device, the downlink communication beamformed in the spatial direction based on the signal received from the wireless communication device.

    Abstract: Apparatus, methods, and computer-readable media for cooperative relay in sidelink networks are disclosed herein. An example method for wireless communication at a first user equipment (UE) includes receiving, from a second UE, a groupcast signal comprising a resource allocation assigned to a plurality of sidelink UEs including the first UE. The example method also includes communicating, with a remote apparatus on a first resource included in the resource allocation, a first relay signal comprising at least a portion of the groupcast signal, in which the first relay signal corresponds to at least a portion of a second relay signal communicated with the remote apparatus on a second resource included in the resource allocation by at least one other sidelink UE of the plurality of sidelink UEs.

    Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may be receive a grant configuration including multiple set of parameters, and the UE may select a set of parameters from the configured grant based on a channel condition. In some examples, the UE may be configured to signal to a network (e.g., a base station) the selected set of parameters and their corresponding parameter values. For example, the UE may be configured to signal the selected set of parameters over semi-static signaling (e.g., radio resource control (RRC) messaging) or dynamic signaling (e.g., medium access control-control element (MAC-CE) messaging, uplink control information (UCI) messaging, or the like). By configuring the UE with multiple set of parameters, the UE may adapt to changing channel conditions, which may provide higher reliability and lower latency for wireless communications, as well as reduce power consumption for the UE.

    Abstract: Methods, systems, and devices for wireless communications are described. Generally, a user equipment (UE) may monitor multiple synchronization signal resources, each synchronization signal resource associated with a beam of a set of beams and may determine that multiple candidate beams of the set of beams satisfy a channel quality threshold. The UE may transmit an indication that the multiple candidate beams satisfy the channel quality threshold. For example, the UE may transmit a single random access message on a physical random access channel (PRACH) resource associated with multiple candidate beams, or may transmit multiple random access messages, each one on a different PRACH resource associated with a different candidate beam. The UE may receive an indication of one of the candidate beams from the base station and may establish a connection with the base station using the indicated candidate beam.

    Abstract: Peak to average power ratio (PAPR) reduction with respect to signals of component carriers of a carrier aggregation configuration may be provided using preconfigured or fixed PRT location sequences (e.g., fixing the number and location of PRTs). A device transmitting signals of component carriers of a carrier aggregation configuration may perform PRT magnitude and phase optimization processing with respect to PRTs of a PRT location sequence using techniques, such as may use a signal to clipping noise ratio, tone reservation (SCR-TR) algorithm. Various PRT location sequence configurations, such as PRT sideband location sequence configurations, PRT inband location sequence configurations, etc., may be selected to facilitate reduction of PAPR associated with the data tones of one or more carrier aggregation component carriers, such as to satisfy a PAPR threshold. Other aspects and features are also claimed and described.
