Abstract: An equalization training method and apparatus are described. The method includes obtaining a training rate of each of a master chip and a slave chip in a target phase of equalization training. The method also includes determining a target rate threshold interval within which the training rate in the target phase falls, determining, based on a correspondence between N+1 rate threshold intervals and N+1 equalization timeout periods, a target equalization timeout period corresponding to the target rate threshold interval, and configuring the target equalization timeout period as an equalization timeout period in the target phase. According to this method, an equalization timeout period used for equalization training can be flexibly configured for each equalization training process, so that the configured equalization timeout period better conforms to a training rate currently used for link negotiation, to better ensure that an equalization parameter is found within the configured equalization timeout period, thereby improving an equalization training success rate.

Abstract: This application provides a drive and a data transmission method, to implement low-latency transmission. The drive includes a CDR circuit, an elastic buffer, a receiver circuit, and a transmitter circuit. The CDR circuit is configured to recover a receive clock from a received signal. The receiver circuit is configured to recover sent data from the received signal by using the receive clock. The elastic buffer is configured to move the sent data in by using the receive clock and move the data out by using the receive clock. The transmitter circuit is configured to send the sent data from the elastic buffer by using the receive clock.

Abstract: A terminal scheduling method and apparatus, a base station, and a medium are disclosed. In an example method, when a physical downlink control channel (PDCCH) allocated for downlink control information (DCI0) used to schedule a terminal device is located in common search space, and enable uplink 256QAM is configured for the terminal device, the base station determines that a modulation and coding scheme (MCS) index value in the DCI0 is 0. The base station sends the DCI0 to the terminal device through the PDCCH.

Abstract: A retimer application system is provided, which includes a primary chip, a retimer, and a secondary chip. After first link training is completed, the retimer is configured to store, in a first storage area, an equalization parameter corresponding to each rate during the first link training, and data stored in the first storage area is not lost when the retimer performs a reset operation. The retimer is further configured to: receive a reset indication, and perform the reset operation according to the reset indication. The primary chip and the secondary chip are configured to perform second link training triggered by the reset indication. During the second link training, the retimer is further configured to: invoke the equalization parameter, and transparently transmit a training sequence in the second link training to the primary chip or the secondary chip based on the equalization parameter.
