Abstract
An operation method of a terminal in a wireless communication system includes receiving a preamble sequence from a base station; estimating a UL channel between the terminal and the base station based on the preamble sequence; determining a first frequency region for transmitting a data signal and a second frequency region for transmitting a jamming signal in an entire frequency region of the UL channel based on a result of estimating the UL channel; and transmitting to the base station a UL control signal including identification information for identifying the first frequency region and the second frequency region.
Claims18
An operation method of a terminal in a wireless communication system, the operation method comprising:
- receiving a preamble sequence from a base station;
- estimating an uplink (UL) channel between the terminal and the base station based on the preamble sequence;
- determining a first frequency region for transmitting a data signal and a second frequency region for transmitting a jamming signal in an entire frequency region of the UL channel based on a result of estimating the UL channel;
- and
- transmitting to the base station a UL control signal including identification information for identifying the first frequency region and the second frequency region.
An operation method of a base station in a wireless communication system, the operation method comprising:
- receiving an uplink (UL) control signal including identification information for identifying a first frequency region in which a data signal is transmitted and a second frequency region in which a jamming signal is transmitted from a terminal through a UL channel;
- receiving a UL transmission signal including the data signal and the jamming signal from the terminal through the UL channel;
- identifying the first frequency region and the second frequency region among an entire frequency regions of the UL channel based on the identification information;
- and
- decoding the data signal received through the first frequency region.
