DATA TRANSMISSION METHOD, FORWARDING METHOD, RECEPTION METHOD, DEVICE, AND SYSTEM

摘要

Embodiments of the present invention provide a data sending method, forwarding method, receiving method, apparatus, and system, and relate to the field of communications technologies. The method includes: pre-storing data that needs to be sent to a target user equipment to a public logical channel buffer in a base station; selecting a user equipment meeting a predefined condition from a user equipment within a short-distance transmission range of the target user equipment as a transit user equipment; and sending the data in the public logical channel buffer to at least the transit user equipment, so that the transit user equipment forwards the data to the target user equipment. This solves the problem in the prior art that the size of data a base station pre-distributes to a logical channel buffer corresponding to each user equipment for buffering cannot precisely match the size of data the base station needs to schedule and send to the user equipment in an actual sending process and therefore low data transmission efficiency is caused due to unreasonable pre-distribution.
