Abstract
Provided is a base station comprising a multiplexer so constituted as to frequency-divide/multiplex a first channel for transmitting first data to be transmitted to a plurality of mobile stations, and a second channel for transmitting second data to be transmitted to one mobile station.
Claims9
A base station comprising:
- a multiplexing unit configured to multiplex a first channel and a second channel in accordance with frequency division multiplexing via a guard band such that the first channel and the second channel have a desired frequency bandwidth,
- wherein the first channel is for transmitting first data to be transmitted to multiple mobile stations, and the second channel is for transmitting second data to be transmitted to one mobile station,
- wherein the multiplexing unit multiplexes an L1/L2 control channel into both a frequency band for transmitting the first channel and a frequency band for transmitting the second channel, and
- wherein the first data of the first channel and the second data of the second channel have a cyclic prefix of different length, and L1/L2 control information in the first and second channels has a cyclic prefix of same length.

A frequency division multiplexing communication method, comprising the steps of:
- generating a first channel for transmitting first data to be transmitted to multiple mobile stations;
- generating a second channel for transmitting second data to be transmitted to one mobile station;
- and
- multiplexing the first channel and the second channel in accordance with frequency division multiplexing via a guard band such that the first channel and the second channel have a desired frequency bandwidth,
- wherein the multiplexing step comprises multiplexing an L1/L2 control channel into both a frequency band for transmitting the first channel and a frequency band for transmitting the second channel, and
- wherein the first data of the first channel and the second data of the second channel have a cyclic prefix of different length, and L1/L2 control information in the first and second channels has a cyclic prefix of same length.
