Abstract: Aspects for reducing interference between networks are provided. A signal transmitted by one or more devices in a first network over a communications medium using an unlicensed frequency spectrum is decoded to determine one or more parameters of a packet in the signal. A level of utilization of the communications medium by the one or more devices in the first network can be estimated based at least in part on a signal strength of the signal and the one or more parameters. A period of time for communicating in a second network over the communications medium using the unlicensed frequency spectrum can be adjusted based at least in part on the level of utilization of the communications medium by the first network. In addition, a number of active transmitters over the communications medium can be determined based at least in part on identifying a source entity related to transmission of the signal, and adjusting the time for communicating in the second network can be further based at least in part on the number of active transmitters.

Abstract: Techniques are described for wireless communication at a wireless communication device. One method includes obtaining a plurality of signal strength samples for a first wireless channel during a measurement period; determining a loading parameter of the first wireless channel based at least in part on a distribution of the signal strength samples for the first wireless channel among a set of predefined signal strength bins; and selecting a wireless operating channel based at least in part on the determined loading parameter of the first wireless channel.

Abstract: A method includes determining a current state of an environment of an autonomous agent, such as a vehicle. The method also includes determining, via a first neural network, a set of actions based on the current state. The method further includes determining whether further analysis of the set of actions is desired. The method selects an action from the set of actions using a model-based solution based on a reward and a risk of the action when further analysis is desired. The method also includes selecting the action from the set of actions according to a metric when further analysis is not desired. The method controls the autonomous agent to perform the selected action.

Abstract: Techniques for co-existence between wireless Radio Access Technologies (RATs) are disclosed. During an active period of a Discontinuous Transmission (DTX) communication pattern, a first signal may be transmitted during a first subframe and a second signal may be transmitted during a second subframe, while during an inactive period the first signal may be transmitted during the first subframe and the second signal may be omitted during the second subframe. Retransmission of one or more packets may take place over a subset of less than all retransmission opportunities based on the DTX communication pattern. A Secondary Cell (SCell) may be reconfigured as the Primary Cell (PCell) and the PCell may be reconfigured as the SCell for one or more access terminals based on a load balancing condition or a channel selection condition.

Abstract: Methods, systems, and devices for wireless communication are described. A transmitting wireless device may select a direction for a wireless transmission over a channel The transmitting wireless device may monitor an availability of the channel in the selected direction for a duration of a first channel listening time corresponding to the selected direction. The transmitting wireless device may determine that the channel is available in the selected direction based on either an absence of channel reservation messages during the monitoring, or a first channel reservation message received during the monitoring. The first channel reservation message may indicate a permissibility of a simultaneous transmission in the selected direction. The transmitting wireless device may transmit a second channel reservation message to a receiving wireless device over the channel in the selected direction based on the determination that the channel is available in the selected direction.

Abstract: Techniques for managing operation over a communication medium shared between Radio Access Technologies (RATs) are disclosed. In one example, one or more parameters of a Time Division Multiplexing (TDM) communication pattern may be set to define activated periods and deactivated periods for communication over the medium. A first interlace may be selected among a plurality of interlaces for communication over the medium, the first interlace being reserved for a first operator. During the first interlace, transmission over the medium may be cycled in accordance with the TDM communication pattern, and deactivated during a second interlace among the plurality of interlaces that is reserved for a second operator.
