Abstract
A wireless communication system in which a terminal selects a signal from a plurality of known signals and transmits the signal to the base station by any region in a region specified by the base station. The wireless communication system includes a setting unit that sets a region by a frequency range and a time interval as the region to be specified, wherein the region set by the setting unit and a region set by another neighboring base station have a same frequency range and a same time interval.
Claims18
A wireless communication system comprising:
- a base station configured to specify a contention region, which is included in an uplink (UL) subframe, by a frequency range and a time interval;
- and
- a terminal to select a signal from a plurality of known signals in accordance with a purpose of use of the signal and to transmit the signal to the base station by a part of the contention region specified by the base station;
- wherein the contention region specified by the base station and a contention region specified by a neighboring base station have a same frequency range and a same time interval, and the purpose of use of the signal for the base station is different from a purpose of use of the signal for the neighboring base station.
A base station in a wireless communication system, the base station comprising:
- a transmitter configured to transmit control information that specifies a contention region, which is included in an uplink (UL) subframe, by a frequency range and a time interval;
- and
- a receiver configured to receive a signal that is selected from a plurality of known signals in accordance with a purpose of use of the signal by a terminal, and that is transmitted to the base station by a part of the contention region;
- wherein the contention region specified by the base station and a contention region specified by a neighboring base station have a same frequency range and a same time interval, and the purpose of use of the signal for the base station is different from a purpose of use of the signal for the neighboring base station.
A transmitting method used in a wireless communication system, the transmitting method comprising:
- specifying a contention region, which is included in an uplink (UL) subframe, by a frequency range and a time interval;
- and
- receiving a signal that is selected from a plurality of known signals in accordance with a purpose of use of the signal by a terminal, and that is transmitted to the base station by a part of the contention region;
- wherein the contention region specified by the base station and a contention region specified by a neighboring base station have a same frequency range and a same time interval, and the purpose of use of the signal for the base station is different from a purpose of use of the signal for the neighboring base station.
