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: Methods, systems, and devices for wireless communication are described. A communication device, which may be known as user equipment (UE), may determine a set of resources for a channel access procedure (e.g. a listen-before-talk (LBT) operation) in a shared radio frequency spectrum band. The set of resources may include one or more zero-power reference signal (ZP-RS) resources, one or more reserved channel access resources, or both. The UE may perform, while operating in a full duplex mode and during a duration in which the UE has not been scheduled to receive any downlink transmission, the channel access procedure on the set of resources for a channel in the shared radio frequency spectrum band. Based on the result of the channel access procedure, the UE may transmit an uplink transmission over the channel.

Abstract: Aspects of the disclosure provide for a thin control channel structure that can be utilized to enable multiplexing of two or more data transmission formats. For example, a thin control channel may carry information that enables ongoing transmissions utilizing a first, relatively long transmission time interval (TTI) to be punctured, and during the punctured portion of the long TTI, a transmission utilizing a second, relatively short TTI may be inserted. This puncturing is enabled by virtue of a thin channel structure wherein a control channel can carry scheduling information, grants, etc., informing receiving devices of the puncturing that is occurring or will occur. Furthermore, the thin control channel can be utilized to carry other control information, not being limited to puncturing information. Other aspects, embodiments, and features are also claimed and described.

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: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may support various extended reality (XR) applications. In some examples of XR applications, features from the real and virtual environments may be overlaid and displayed to a user for consumption via the UE. To avoid visual conflicts, such as misaligning objects from the real and virtual environments, and other visual conflicts, the UE may generate and send pose information to a network (e.g., a server hosting the XR application). The UE may be configured to manage transmission of pose information to the network, which may result in reduced power consumption. For example, the UE may determine a downlink burst occasion for the XR application, generate pose information associated with the UE and the XR application, and transmit the pose information only during the downlink burst occasion.

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 synchronization signal resources, each synchronization signal resources associated with a beam, and may select a preferred beam based on the monitoring. The UE may transmit an uplink random access message (e.g., message 3 of a four-step random access message, message A of a two-step random access procedure, or a negative acknowledgement (NACK) message requesting retransmission of a random access message) including beam information (e.g., one or more beam indices, channel quality information, or channel state information) to a base station. In response, the base station may transmit a downlink random access message using a different beam (e.g., a new preferred beam). The UE may establish a connection with the base station based on the completed random access procedure.

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.
