Abstract
The present disclosure provides an uplink signal transmission method, user equipment (UE) and base station. When the UE transmits uplink signals in an unlicensed frequency band after receiving uplink synchronization command information, the UE transmits one or more uplink signals according to a predefined time or a time indicated by the base station. The UE determines mapping of an uplink signal according to the predefined time or the indicated time. When provided with the present disclosure, interference between signals of a same type or between signals of different types can be reduced and a signal transmission probability can be improved accordingly.

1-14. (canceled)
A method for transmitting data by a terminal in a communication system supporting a licensed assisted access (LAA), the method comprising:
- receiving, from a base station, information for a starting position of a physical uplink shared channel (PUSCH);
- and
- transmitting, to the base station, data based on the information for the starting position of the PUSCH.
A method for receiving data by a base station in a communication system supporting a licensed assisted access (LAA), the method comprising:
- transmitting, to a terminal, information for a starting position of a physical uplink shared channel (PUSCH);
- and
- receiving, from the terminal, data based on the information for the starting position of the PUSCH.
A terminal in a communication system supporting a licensed assisted access (LAA), the terminal comprising:
- a transceiver;
- and
- a processor coupled to the transceiver and configured to:
- control the transceiver to receive, from a base station, information for a starting position of a physical uplink shared channel (PUSCH), and
- control the transceiver to transmit, to the base station, data based on the information for the starting position of the PUSCH.
A base station in a communication system supporting a licensed assisted access (LAA), the base station comprising:
- a transceiver;
- and
- a processor coupled to the transceiver and configured to:
- control the transceiver to transmit, to a terminal, information for a starting position of a physical uplink shared channel (PUSCH), and
- control the transceiver to receive, from the terminal, data based on the information for the starting position of the PUSCH.
