Abstract: A method of wireless communication by a user equipment (UE) receives a channel state information (CSI) decoder and CSI encoder from a base station on a physical downlink control channel (PDSCH) or a media access control-control element (MAC-CE). The method also includes training the CSI decoder and CSI encoder based on observed channel and interference conditions to obtain updated decoder coefficients and updated encoder coefficients. The method further includes receiving an indication of resources for transmission of the updated encoder coefficients and updated decoder coefficients. The method includes transmitting the updated decoder coefficients and updated encoder coefficients to the base station in accordance with the indication of resources. Further, the method includes receiving an updated CSI decoder and updated CSI encoder from the base station for further training.

Abstract: Methods, systems, and devices for wireless communications are described. A base station of a wireless communications system may transmit, to a user equipment (UE), a configuration message that indicates a transmission time interval (TTI) format for a plurality of TTIs. At least one format for the plurality of TTIs includes uplink resources and downlink resources separated in the frequency domain, which may be an example of a subband full duplex (SBFD) slot. Since the pattern may include some transitions between uplink and downlink resources, one or more gap periods (e.g., time gaps) may be positioned between such resources.

Abstract: A method, a computer-readable medium, and an apparatus are provided for wireless communication at a receiver. The apparatus is configured to receive a non- coherent signal and determine a first differential of the received non-coherent signal on each of one or more receive antennas for a set of binary vectors to obtain a lower order representation of the non-coherent signal. The apparatus is configured to combine the differentials across antennas, decode the lower order representation of the non-coherent signal based on the first differential of the non-coherent signal and to reconstruct a higher order representation of the non-coherent signal based on the decoded lower order representation of the non-coherent signal.

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: Aspects are provided which allow a base station to provide RACH configuration(s) indicating RACH occasions which correspond to wake up occasions of a base station according to a power savings mode of the base station. The base station sends one or more RACH configurations indicating ROs to a UE, and then monitors the ROs associated with the power savings mode. The UE determines the ROs associated with the power savings mode, and sends a wake up signal to the base station in at least one of the determined ROs. The base station obtains the wake up signal from the UE in at least one of the monitored ROs. Here, the wake up signal comprises a RACH message. As a result, network power consumption may be optimized through designed configurations which allow a UE to wake up a sleeping base station via a RACH message.

Abstract: Methods, systems, and devices for wireless communications are described. In some wireless communications systems, a user equipment (UE) may receive, from a base station, control signaling identifying a configuration of a set of time intervals for communication with the base station, the set of time intervals including a subset of the time intervals for which the UE is to perform a physical layer security procedure. In some cases, the UE may activate a timer associated with performing the physical layer security procedure in response to a trigger. The UE and the base station may communicate one or more messages using the physical layer security procedure, for example, in the subset of the time intervals identified by the control signaling, while the timer is active, or both. The physical layer security procedure may involve the UE performing physical layer security encoding, signal jamming, or both.

Abstract: Disclosed are techniques for wireless communication. In an aspect, an assisting user equipment (UE) receives a request to perform a positioning procedure from a target UE over a sidelink between the assisting UE and the target UE, wherein the assisting UE and the target UE are both out of network coverage, determines, based at least on the request, a set of time and/or frequency resources on which to transmit one or more positioning reference signals for the positioning procedure, and transmits the one or more positioning reference signals to the target UE via the set of time and/or frequency resources.
