Abstract
The present disclosure discloses an uplink (UL) signal transmission method, apparatus and system, for effectively reducing channel resource overhead while protecting UL channel access opportunities. An uplink signal transmission method implemented on a UE side comprises: a UE determining, from at least one predefined candidate transmission position according to a preset rule, a transmission start position for transmitting an uplink signal; and beginning transmitting of the uplink signal at the determined transmission start position. In an uplink signal transmission method implemented on a base station side, an uplink scheduling grant (UL grant) is sent to schedule a UE to perform uplink transmission, and an uplink subframe sent by the UE is received; and a transmission start position of the uplink signal is determined in the uplink subframe.
