Abstract: Methods, systems, and devices for wireless communications are described. A first device may receive a first reference signal from a second device and may generate a channel status feedback message based on the first reference signal. The first device may bundle the second reference signal and the channel status feedback message and may transmit the second reference signal and the channel status feedback to the second device. The first device may initiate a data transfer with the second device based on transmitting the second reference signal and the channel status feedback message.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may perform a measurement operation to attain multiple measurements to report to a base station. The measurements may correspond to a first number of bits if reported. The UE may compress the measurements using an encoder neural network (NN) to obtain an encoder output indicating the measurements. This encoder output may include a second number of bits that is less than the first number of bits. The UE may report the encoder output to the base station in this compressed form. At the base station, the encoder output may be decompressed according to a decoder NN. Once the base station decompresses the encoder output, the UE and base station may communicate according to the measurements determined from the decompression. In some cases, the base station may perform load redistribution based on the measurements.

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: Aspects of the present disclosure provide a time division duplex (TDD) subframe structure that supports both single and multiple interlace modes of operation. In a single interlace mode, control information, data information corresponding to the control information and acknowledgement information corresponding to the data information are included in a single subframe. In a multiple interlace mode, at least one of the control information, the data information corresponding to the control information or the acknowledgement information corresponding to the data information is included in a different subframe. Both single and multiple interlace modes can be multiplexed together within the TDD subframe structure.

Abstract: Embodiments include methods for managing information transmission between a base station and a wireless device. A base station may apply an encoder neural network to assistance information that may aid a wireless device in communicating with the base station to generate encoded assistance information. The base station may transmit the encoded assistance information to the wireless device via a control or data channel. The wireless device may use the encoded assistance information to update one or more behaviors of the wireless device without decoding the encoded assistance information. The wireless device may include a different neural network configured to learn how to use the encoded assistance information to update one or more behaviors of the wireless device.

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: 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.
