    Abstract: This application provides an uplink multi-station channel estimation method, a station (STA), and an access point (AP), which can be applied to an uplink multi-user multiple-input multiple-output scenario. The uplink multi-station channel estimation method includes: a STA generating a frame including a first group of training sequences and a second group of training sequences, and sending the frame to the AP. The AP calculates a frequency offset value between the STA and the AP based on the received first group of training sequences and the received second group of training sequences. The AP performs channel estimation based on the calculated frequency offset value. According to the technical solutions provided in this application, the AP can more accurately learn of frequency offset values between a plurality of STAs and the AP.

  • Publication number: 20220200722
    Abstract: This application relates to a slot negotiation method and a device. The method includes: A transmitter sends a first FlexE overhead frame to a receiver, to request active/standby calendar switching. When the receiver is in a restart state, the receiver does not respond to the received first FlexE overhead frame. In addition, the RX sends a routine update second FlexE overhead frame to the transmitter. Determining that the second FlexE overhead frame is not a response to the first FlexE overhead frame, the transmitter sends a third FlexE overhead frame to request active/standby calendar switching again. According to the method in this application, incorrect calendar switching on the transmitter side caused by a mistaken response of the receiver can be avoided. This reduces the likelihood of a service interruption caused by the existing slot negotiation mechanism.

  • Publication number: 20220197614
    Abstract: A method and apparatus to optimize a list of vector instructions using dynamic programming, in particular memoization, by generating a table containing instruction subvectors having individual (parts), contiguous (superparts) and repeated (broadcasts) lanes. Because the instructions in the table are subvectors selected to have individual, contiguous and repeated lanes in the registers, compiler optimizations can be enhanced. Introduction of such dynamic programming allows for speculative lane optimizations, as well as improved analysis-guided optimizations, either of which can be performed alone or in combination with other optimizations, whether or not they make use of dynamic programming.
