    Abstract: A network may transmit either beam deployment information or beam number information to a user equipment (UE) carried on a train and configured for operation in the millimeter wave band. The deployment information may include deployment related distance parameters or azimuth angle spread parameters. The beam number information may indicate a number of network beams associated with a current cell. The UE may determine a number of UE receive beams based on deployment information or the network-indicated number of network beams. The UE may transmit feedback to the network, indicating the number of UE receive beams. Alternatively, the network may send a configuration message indicating a first number of UE receive beams to the UE, which the UE may treat as an upper bound or lower bound in its determination of a desired number of UE receive beams. The UE may transmit the desired number to the network.

    Abstract: This disclosure relates to techniques for a wireless device to initiate channel occupancy in unlicensed spectrum in a wireless communication system. The wireless device may establish a wireless link with a cellular base station. The wireless device may determine to perform an uplink transmission to the cellular base station on an unlicensed frequency channel. The wireless device may determine whether the cellular base station has channel occupancy of the unlicensed frequency channel. The wireless device may determine whether to initiate channel occupancy of the unlicensed frequency channel. The decision whether to initiate channel occupancy may be based at least in part on whether the cellular base station has channel occupancy of the unlicensed frequency channel.

    Abstract: An electronic device in a wireless power system may be operable with a removable accessory such as a case. The device may convey wireless power to, from, or through the case while the device is coupled to the case. The device may have coplanar power transmitting and power receiving coils. The removable accessory may have an embedded switchable ferrimagnetic core and a coil that overlaps the switchable ferrimagnetic core. The switchable ferrimagnetic core may be operable in a first state where the switchable ferrimagnetic core is unsaturated. The switchable ferrimagnetic core may be operable in a second state where the switchable ferrimagnetic core is saturated by a magnetic field from a permanent magnet in a wireless power transmitting device. In the second state, the switchable ferrimagnetic core may have a lower magnetic permeability and higher magnetic reluctance than in the first state.

    Abstract: Techniques are disclosed relating to distributing geometry work in a graphics processor. In some embodiments, multiple geometry pipelines are configured to process, in parallel, multiple segments of a set of geometry work. In some embodiments, control circuitry is configured to split operations from the set of graphics work into the multiple segments. This may include parsing a control stream for the set of graphics work to determine an initial work estimate based on numbers of primitives in different draw calls and adjusting the initial work estimate based on a complexity determination for the draw call.

    Abstract: An apparatus includes a processor core that includes an instruction decode circuit and a control circuit. The instruction decode circuit is configured to decode instructions, including a plurality of store instructions used to store information in a memory hierarchy. The control circuit is configured, after a particular store instruction is decoded, to preserve store information related to the particular store instruction, including a first program counter value for the particular store instruction. In response to decoding a subsequent load instruction with a corresponding second program counter value, the control circuit is configured to determine, using the first and second program counter values, whether a dependency has been established between the subsequent load instruction and the particular store instruction. In response to a determination that the dependency has been established, the control circuit is configured to use the preserved store information to perform the subsequent load instruction.

    Abstract: The present disclosure generally relates to user interfaces that include application widgets. In some embodiments, a computer system displays a home screen, where displaying the home screen includes displaying a set of user interface elements based on whether an account that was used to set up the computer system is associated with a first type of content. In some embodiments, a computer system displays a user interface in response to detecting a request to change the orientation of the user interface. Displaying the user interface includes displaying an arrangement of application widgets and application icons, where a set of application widgets has a same spatial organization as in a previous arrangement.
