Abstract: Embodiments of the present invention provide a wireless communications method, apparatus, and system. A terminal is provided. The terminal sets up a connection to a first base station, and stays in always connected mode. Therefore, when the terminal moves in a dense network, handovers of the first base station can be reduced. Further, when the terminal moves in the dense network, frequent signaling interaction is reduced, paging load in the entire network is reduced, and an end-to-end delay in service setup and transmission is reduced.

Abstract: Embodiments of the present invention disclose a systematic code decoding method and an apparatus. The method includes: extracting a non-erased original packet from an acquired encoded packet that has passed through an erasure channel; and then by using the erased original packet as an unknown variable, obtaining an erased original packet by parsing according to a first equation. Because a quantity F of erased original packets is far less than a total quantity K of original packets, a dimension of the first equation that includes F unknown variables is far lower than a dimension of an equation indicating a correspondence between an encoded packet and an intermediate packet. An operation amount required for parsing the relatively low-dimensional first equation is far smaller, thereby greatly reducing an operation amount required for decoding.
