Abstract
There is provided a wireless communication device including a receiving unit that receives a radio signal transmitted from a base station providing a wireless communication service, a congestion calculation unit that calculates a degree of congestion of the wireless communication service based on a received result of the radio signal by the receiving unit, and an effective communication rate estimation unit that estimates an effective communication rate of the wireless communication service by use of the degree of congestion calculated by the congestion calculation unit.
Claims18
A wireless communication device comprising:
- a receiving unit that receives a radio signal transmitted from a base station providing a wireless communication service;
- a congestion calculation unit that calculates a degree of congestion of the wireless communication service based on the radio signal received by the receiving unit,
- wherein the degree of congestion is calculated based on a proportion of a number of allocated subcarriers to a total number of subcarriers;
- and
- an effective communication rate estimation unit that estimates an effective communication rate of the wireless communication service by use of the degree of congestion calculated by the congestion calculation unit.
A non-transitory computer readable medium having stored thereon, a set of computer-executable instructions for causing a computer to perform steps comprising:
- receiving a radio signal transmitted from a base station providing a wireless communication service, wherein the base station transmits the radio signal spectrum-spread by a scrambling code;
- calculating a degree of congestion of the wireless communication service based on a correlation between the received radio signal and the scrambling code;
- estimating an effective communication rate of the wireless communication service by use of the degree of congestion;
- and
- measuring an actual effective communication rate after establishing a connection with the base station.
A wireless communication method comprising:
- receiving a radio signal transmitted from a base station providing a wireless communication service, wherein the base station transmits the radio signal spectrum-spread by a scrambling code;
- calculating a degree of congestion of the wireless communication service based on a correlation between the received radio signal and the scrambling code;
- estimating an effective communication rate of the wireless communication service by use of the degree of congestion;
- and
- measuring an actual effective communication rate after establishing a connection with the base station.
A wireless communication system comprising:
- a base station that provides a wireless communication service;
- and
- a wireless communication device including:
- a receiving unit that receives a radio signal transmitted from the base station,
- a congestion calculation unit that calculates a degree of congestion of the wireless communication service based on the radio signal received by the receiving unit, wherein the degree of congestion is calculated as a proportion of a number of allocated subcarriers to a total number of subcarriers,
- an effective communication rate estimation unit that estimates an effective communication rate of the wireless communication service by use of the degree of congestion calculated by the congestion calculation unit, and
- a measurement unit that measures an actual effective communication rate after establishing a connection with the base station.
