Abstract:
This application relates to clock synchronization methods optical head ends, and optical terminals. In an example method, the optical head end receives a first packet from a controller. The first packet includes service data to be transmitted to a plurality of slave stations. The optical head end generates a second packet based on the first packet. The second packet includes the service data and time information. The time information indicates an execution time point at which the plurality of slave stations perform an operation based on the service data. The optical head end further sends the second packet to the plurality of optical terminals to request the plurality of optical terminals to control the plurality of slave stations to perform the operation at the execution time point based on the service data.
Abstract:
Embodiments of the present invention relate to the communications field, and disclose a method for uplink data transmission, a terminal, and a wireless communication node, which can ensure that a HARQ mechanism between a terminal and a wireless communication node works normally. The method includes: determining, by a first wireless communication node, whether a terminal is within downlink coverage of a second wireless communication node; and when the first wireless communication node determines that the terminal is not within the downlink coverage of the second wireless communication node, instructing, by the first wireless communication node, the terminal to use a non-feedback mode; and/or instructing, by the first wireless communication node, the second wireless communication node to use a non-feedback mode.
