Abstract: Methods and apparatus are described for carrying out timing adjustments in a wireless communications network. The approach includes a user equipment (UE) that includes processor circuitry and a radio front end circuitry. The processor circuitry is configured to obtain a timing advance value for the wireless communication with a satellite base station, and to determine a transmission time for transmission of a random access channel (RACH) preamble based on the timing advance value. The radio front end circuitry transmits the random access preamble at the transmission time. Finally, the processor circuitry is further configured to receive a response to the transmitted random access preamble.

Abstract: An electronic device that communicates frames is described. During operation, the electronic device may transmit the frames addressed to a recipient electronic device and associated with multiple links between the electronic device and the recipient electronic device. Then, the electronic device may receive block acknowledgments for at least a subset of the frames, where a given block acknowledgment is associated with the recipient electronic device and indicates received frames on a given link in the links. Moreover, the electronic device may control an amount of traffic conveyed on the links based at least in part on the block acknowledgments. Next, the electronic device may store a remainder of the frames based at least in part on the block acknowledgments, where the frames include the subset of the frames and the remainder of the frames. Note that the frames may have a common traffic identifier.

Abstract: Apparatus and methods are provided for port selection codebook configuration. A user equipment (UE) may receive, from a base station, an indication of parameter settings of a port selection codebook. The port selection codebook includes a port selection matrix W1, a combinational coefficient matrix W2, and a frequency basis selection matrix Wf. Based at least in part on the parameter settings, the UE selects L CSI-RS ports, Mv frequency basis from a window of N consecutive frequency basis; and up to beta*L*Mv entries per layer, where beta is a percentage of the L*Mv entries per layer. The UE reports one or more of the port selection matrix W1, the up to beta*L*Mv entries in the combinational coefficient matrix W2 per layer, and the frequency basis selection matrix Wf to the base station.

Abstract: A pixel array may be illuminated with backlight illumination from a backlight. The backlight may include a two-dimensional array of light-emitting diodes, with each light-emitting diode being placed in a respective cell. Different light-emitting diodes may have unique brightness magnitudes based on the content of the given display frame. Driver integrated circuits may control one or more associated light-emitting diodes to have a desired brightness level. The driver integrated circuits may be formed in an active area of the backlight. The driver integrated circuits may be arranged in groups that are daisy chained together. A digital signal (that includes information such as addressing information) may be propagated through the group of driver integrated circuits. To manage thermal performance of the backlight, the backlight may include a thermally conductive layer and/or a heat sink structure. To increase the efficiency of the backlight, the backlight may include one or more reflective layers.

Abstract: A cell transmits synchronization signal blocks (SSB) to a user equipment (UE) for the UE to synchronize with the cell. The cell configures a discovery reference signal (DRS) window for synchronization signal block (SSB) transmission to a user equipment (UE), determines that a channel in an unlicensed spectrum is not occupied and transmits multiple SSBs to the UE in response to determining that the channel in the unlicensed spectrum is not occupied.

Abstract: In a wireless communication environment, there may arise a timing misalignment for SRS-RSRP measurement. In order to address this issue, a UE may receive an uplink transmission from second UE containing the uplink transmission timing for the first UE. The UE may then set its measurement timing to be the same as the uplink transmission timing. The UE then carries out SRS-RSRP measurement according to the newly-set measurement timing.

Abstract: A power delivery system included in a computer system using multiple power converter circuits to generate respective voltage levels on multiple power supply nodes. The power delivery system includes a step-down power converter circuit that generates a voltage level for use by host and follower power converter circuits. The host power converter circuit generates an external demand current that is shared by multiple follower power converter circuits to regulate the voltage level on the multiple power supply nodes. The power delivery system can be scaled to different platforms of the computer system by adjusting the number of follower power converter circuits.

Abstract: Multi-sided prism printing systems and processes that apply a light-blocking material (e.g., a polymer) to at least part of the surfaces of at least two sides of a prism at the same time. The multi-sided prism printing systems and processes may significantly increase throughput of prism printing when compared to conventional prism printing methods in which only one side of a prism is printed at a time. In addition, the multi-sided prism printing systems and processes may provide a more accurate alignment of the printed patterns on lateral faces of the prism when compared to conventional prism printing methods in which only one lateral face of a prism is printed at a time.

Abstract: Reporting UL Tx DC sub-carrier location information may include decoding a radio resource control (RRC) message received from a base station. The RRC message may comprise a configuration for dynamically reporting uplink (UL) transmit (Tx) direct current (DC) sub-carrier location information. A change associated with at boast one previous UL Tx DC sub-carrier location may be determined to have occurred, thereby creating at least one new UL Tx DC sub-carrier location. In response to determining the change, a medium access control (MAC) control element (MAC CE) may be encoded for transmission to the base station. The MAC CE may include information corresponding to the at least one new UL Tx DC sub-carrier location.

Abstract: An electronic device may have an inner display mounted in a housing so that an image on the inner display is presented to an eye box through a lens for viewing by a user while the electronic device is being worn on a head of the user.

The metal traces in the border areas can be formed on the same side of the substrate as the patches and columns, but separated from the patches and column-like patterns by a dielectric layer.
