Abstract: A method is described wherein a user equipment (UE) receives first information indicating a direction of data received by a base station in each one of a plurality of time periods. The UE maintains a first list including a sequence of the directions in which the base station receives the data. The sequence indicates channel quality when the base station receives, in the different directions, the data. The UE receives second information indicating listening durations to listen on a channel in the different directions in the first list, and a listening duration corresponding to a direction ranked higher is shorter. The UE determines, in accordance with the start of the first time period and based on the second information, a first listening duration corresponding to the first direction. If the channel is idle within the first listening duration, the UE accesses the channel.

The first transmission chip sends first feedback information to the first device, wherein the first feedback information is used to indicate whether the I2C data is successfully received. The first transmission chip forwards the I2C data to a second transmission chip corresponding to the second device. The first transmission chip receives second feedback information from the second transmission chip, and the second feedback information is used to indicate whether the I2C data is successfully received. The first transmission chip stores the second feedback information in a first storage space that is storage space of the first transmission chip.

Abstract: Embodiments of this application disclose a data processing method, which can be applied to a clock synchronization network system. The system can correct, based on a clock frequency error or a time error, a data timestamp of a data packet collected by the system in a time period in which there is no reference clock, so that a corrected system time of the data packet is consistent with a reference time. This improves accuracy of data record.

Abstract: In embodiments, a UE notifies an AP of information about a home operator of the UE; and the AP determines whether the home operator of the UE uses a hotspot virtualization technology on the AP, and if the home operator uses the hotspot virtualization technology on the AP, sends the information about the home operator of the UE as information about the AP access service operator to the UE, so that in a case in which the home operator of the UE and the AP access service operator are different, the UE considers the AP access service operator as the home operator of the UE and therefore preferentially selects a network of the home operator to access a communications network by using the AP.
