Abstract: Methods, systems, and devices for wireless communications are described. A base station may indicate for a first device to transmit random information in the direction of an adverse device on at least partially overlapping time and frequency resources that are also used for receiving a downlink message from the base station. By transmitting the random information in the direction of the adverse device, the first device may cause entropy overhead to the adverse device, impacting an ability of the adverse device to decode portions of the downlink message transmitted to and intended for the first device. Accordingly, the first device may receive the downlink message and may concurrently transmit the random information in the direction of the adverse device on time and frequency resources that at least partially overlap with time and frequency resources used for receiving the downlink message based on receiving the indication from the base station.

Abstract: Methods, systems, and devices for wireless communications are described. A full-duplex device may perform a channel access procedure using multiple threshold values to determine whether self-interference at the full-duplex device is affecting the channel access procedure. For example, if a first amount of energy detected during a first sensing operation of the channel access procedure is determined to be between a first threshold value and a second threshold value, the full-duplex device may perform a self-interference measurement on the shared channel and may transmit on the shared channel if the self-interference measurement exceeds a self-interference threshold value. Additionally or alternatively, if the self-interference measurement does not exceed the self-interference threshold value, the full-duplex device may refrain from transmitting on the shared channel. In some examples, the self-interference measurement may include a correlation measurement, a signal-to-noise ratio (SNR) measurement, or a combination thereof.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE), operating in a serving cell, may adjust a transmit power of an uplink message when a neighboring cell is operating in an opposite direction (e.g., relative to the direction of communications in the serving cell) within a same or similar frequency band in a same time period. The UE may receive control signaling that indicates a first power control configuration to be used when the neighboring cell is operating in a same direction as the serving cell and a second power control configuration to be used when the neighboring cell is operating in a different direction from the serving cell. The UE may select the appropriate power control configuration based on the communications directions of the serving cell and the neighboring cell and may transmit the uplink message in accordance with the selected power control configuration.

Abstract: Methods, systems, and devices for wireless communications are described. In some cases, a sidelink user equipment (UE) may receive a configuration for performing a channel sensing procedure of a sidelink resource selection procedure for identifying sidelink resource candidates in a resource selection window. The configuration may indicate a first channel metric and a second channel metric for performing the channel sensing procedure. The UE may measure reference signaling in a sensing window according to one or both of the first and second channel metrics based on a duplex mode of the UE while performing the channel sensing. The reference signaling may correspond to a set of sidelink resource candidates in a resource selection window. The UE may determine an available set of sidelink resource candidates for a sidelink transmission from the set of sidelink resource candidates based on the measuring.

Abstract: Methods, systems, and devices for wireless communications are described. In some examples, a user equipment (UE) may receive control signaling indicating a configuration for performing channel sensing. The configuration may include one or more parameters corresponding to a processing time associated with the channel sensing. The UE may adjust the processing time associated with the channel sensing based on the one or more parameters and a full duplex capability of the first UE. The UE may transmit, using a first set of resources, a sidelink message based on the adjusted processing time. In some examples, the UE may transmit a first data message associated with a first priority level and perform channel sensing for a second data message associated with a second priority level that is higher than the first priority level. The UE may drop the first data message, skip an interference cancellation, or a combination thereof.

Abstract: Aspects of the present disclosure relate to methods and apparatus for location encoding for secondary synchronization signals (SSS) to convey additional information, such as a current symbol number. According to aspects, a method is provided herein for wireless communications that may be performed, for example, by a base station (BS). The method generally includes selecting frequency resources to use for transmitting synchronization signals in a symbol of a frame, wherein the frequency resources are selected based on a mapping of frequency resources to a location of the symbol within the frame; and transmitting synchronization signals to at least one user equipment (UE) according to the mapping. As a result, the UE may receive synchronization signals, determine a location of the current symbol in a frame based on the mapping, and synchronize to the BS based on the determined location of the current symbol. Numerous other aspects are provided.

Abstract: An apparatus may utilize an air interface to transmit and/or receive a transmission during a first TTI that includes a second set of data overriding a first set of data scheduled for transmission during the first TTI. The air interface may further be utilized to transmit and/or receive a transmission after a duration of time that is less than a total time duration of the first TTI that includes a control channel that is at least partially embedded in a data portion of a subframe. The control channel may include an override indicator configured to indicate that the first set of data scheduled for transmission during the first TTI is overridden by the second set of data having the higher priority. The override indicator may be transmitted after the second set of data is transmitted. The one or more additional TTIs may be after the first TTI.

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 and methods facilitating feedback of robust channel state information (CSI), such as to provide full CSI feedback or otherwise providing CSI feedback, are described. CSI encoders and/or decoders used by network nodes may implement channel compression/reconstruction based upon neural-network (NN) training of collected channels. A structured payload having an interpretable payload portion and an uninterpretable payload portion may utilized with respect to CSI feedback. The channel compression provided according to some aspects of the disclosure supports feedback of robust CSI, in some instances including full CSI, as determined by a particular network node. Other aspects and features are also claimed and described.
