Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a set of reference signals from a base station and may determine a first set of channel state parameters. The UE may determine one or more preprocessed decoder parameters based on a downlink channel decoder of the UE and may perform one or more signal processing operations to determine one or more adjustment values for the first set of channel state parameters. The UE may transmit an indication of a the one or more adjustment values to the base station. In some implementations, the UE may transmit an indication of the one or more preprocessed decoder parameters to the base station and the base station may perform the one or more signal processing operations to determine the one or more adjustment values.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, from a base station, a request that the UE report a predicted future channel state information measurement. Upon receiving the request, the UE may measure, during a first time period, a channel to obtain measured channel state information. The UE may then determine the predicted future channel state information for a second time period based on the measured channel state information. In some case, the second time period may be subsequent to the first time period. Upon determining the predicted future channel state information measurement, the UE may transmit, to the base station, a channel state information report. In some aspects, the channel state information report may be indicative of the predicted future channel state information measurement.

Abstract: Methods, systems, and devices for wireless communication are described for monitoring interference level to selectively control usage of a contention-based protocol. In an example, a wireless device may transmit, while operating in a non-contention-based mode for a wireless link with a second wireless device, a first beamformed data transmission to the second wireless device over a shared channel. The wireless device may determine that an interference level condition is satisfied for the shared channel and transition from operating in the non-contention-based mode to operating in a contention-based mode for the wireless link based at least in part on the interference level condition being satisfied. The wireless device may perform a contention-based protocol, while operating in the contention-based mode for the wireless link with the second wireless device, prior to transmission of a second beamformed data transmission to the second wireless device over the shared channel.

Abstract: Methods, systems, and devices for wireless communications are described. A wireless device may determine an interference status of each beam configuration of a plurality of active beam configurations for a shared radio frequency spectrum band. The wireless device may determine a beam-specific listen-before-talk (LBT) requirement for each beam configuration of the plurality of active beam configurations based at least in part on the determined interference status of each beam configuration. The wireless device may selectively enable an LBT procedure on a per-beam basis according to the determined beam-specific LBT requirement for each beam configuration.

Abstract: Techniques for managing preamble transmission and processing on a shared communication medium are disclosed. An access point or an access terminal, for example, may generate a preamble for silencing communication on a communication medium with respect to an upcoming data transmission, configure the preamble to identify one or more target devices for the silencing, and transmit the preamble over the communication medium in advance of the data transmission. Conversely, the access point or the access terminal may receive a preamble (as a receiving device) over a communication medium, identify one or more target devices for silencing communication on the communication medium with respect to an upcoming data transmission based on the preamble, and selectively silence communication over the communication medium based on itself (as the receiving device) being among the one or more target devices.

Abstract: Methods, systems, and devices for wireless communications are described. A wireless device may select a transmission beam sequence for a wireless device during a plurality of transmission slots. The transmission beam sequence may indicate a transmission beam that the wireless device will use for its transmissions during a corresponding transmission slot. The wireless device may transmit a broadcast control signal including an indication of the transmission beam sequence. The wireless device may perform wireless transmissions over the plurality of transmission slots according to the transmission beam sequence. Other wireless devices may use the transmission beam sequence to schedule their own transmissions during the plurality of transmission slots.

Abstract: Soft channel reservation in shared spectrum networks is discussed. In network areas where multiple wireless nodes, whether from the same or different network operators, share spectrum using a channel reservation signaling form of contention resolution, an aggressor transmitter listens for a neighbor receiver's receiver channel reservation signal to the neighbor transmitter the neighbor receiver is in communication with. The receiver channel reservation signal includes channel condition information that the aggressor transmitter can use to estimate an interference impact at the neighbor receiver should the aggressor transmitter performs its transmissions to its own receivers. Based on whether this estimated interference impact exceeds or remains within a particular threshold, the aggressor transmitter may decide whether or not to back off of its transmissions until a later time.

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.
