    摘要: A semiconductor device is used as one of a plurality of slaves connected in multiple stages to a master and transmits a frame signal output from the master sequentially from a preceding stage to a subsequent stage. The frame signal includes synchronization bits and a message string (for example, command bits, address bits, and guard bits) following the synchronization bits. The semiconductor device includes a logic circuit configured to sample the frame signal at a baud rate corresponding to the synchronization bits and an output stage configured to through-outputs the synchronization bits before sampling without passing them through the logic circuit.

    摘要: This disclosure relates to techniques for a wireless device to perform channel state information reporting. The wireless device may receive channel state information reporting configuration information. The channel state information reporting configuration information may include an indication to use a wideband precoding matrix indicator format for 3GPP release 16 type II channel state information reporting. The wireless device may perform channel state information reporting using a different reporting configuration than 3GPP release 16 type II channel state information reporting using a wideband precoding matrix indicator format based at least in part on the channel state information reporting configuration information. The wireless device may also or alternatively perform 3GPP type I channel state information reporting using a unified spatial basis selection framework for rank indicators of 3 and 4 for any number of channel state information reference signal ports.

    摘要: The present disclosure relates to a network device, a method executed by the network device, and a computer-readable medium. Some aspects of the present disclosure relate to a first network device, including a memory, on which instructions are stored, and a processor configured to execute the instructions stored on the memory to cause the first network device to execute the following operations: executing channel scanning on a main working channel of a second network device coupled to the first network device to detect a beacon frame broadcast by the second network device; determining whether a beacon frame broadcast by the second network device is detected within a first predetermined time duration; and at least partially in response to the determination that no beacon frame broadcast by the second network device has been detected within the first predetermined time duration, causing the second network device to automatically restart its Wi-Fi module.

    摘要: Provided are a time synchronization method and device, and a storage medium. The method includes that: a synchronized block matching a preset code pattern in a data stream is searched at a SERDES parallel interface; the position of the bit of the synchronized block in the SERDES parallel interface is determined as a first position; a time point when the synchronized block passes through the SERDES parallel interface is determined as a first time point; the synchronized block and a PTP packet in the data stream are searched at an interface between PHY layer and MAC layer, and a distance between the synchronized block and the PTP packet is determined; and a second time point is determined according to the first position, the first time point and the distance, the second time point being the time point when the PTP packet passes through an SERDES serial interface.

    摘要: Laser Grid Structures for Wireless High Speed Data Transfers Disclosed herein are various embodiments for high performance wireless data transfers. In an example embodiment, laser chips are used to support the data transfers using laser signals that encode the data to be transferred. The laser chip can be configured to (1) receive a digital signal and (2) responsive to the received digital signal, generate and emit a variable laser signal, wherein the laser chip comprises a laser-emitting epitaxial structure, wherein the laser-emitting epitaxial structure comprises a plurality of laser-emitting regions within a single mesa structure that generate the variable laser signal. Also disclosed are a number of embodiments for a photonics receiver that can receive and digitize the laser signals produced by the laser chips. Such technology can be used to wireless transfer large data sets such as lidar point clouds at high data rates.
