1. A terminal, comprising:
- a transmission data generating unit configured to generate multi-cell transmission data by repeating a data group comprising a plurality of data bits, the repeated data group comprising at least two repetitions of the plurality of data bits, and the number of repetitions of the plurality of data bits generated is determined based on a transmission delay of the terminal or at least one other terminal; and
a transmission unit configured to transmit the multi-cell transmission data comprising the repeated data group to each of a plurality of base stations,wherein a total window duration is set while the multi-cell transmission data is received, based on the transmission delay of the terminal or the at least one other terminal,a maximum value of the transmission delay is determined to be a starting time of a first window duration,an end point in time of the multi-cell transmission data is determined to be an end time of the first window duration,data bits not included in the first window duration from among the repeated data groups are set as a second window duration, andthe first window duration and the second window duration are set as the total window duration.

Abstract
A communication system and method that receives data from a terminal using a cooperative reception scheme, is provided. Each terminal may generate multi-cell transmission data used for overcoming transmission delay and transmit, to each base station, a data frame including the multi-cell transmission data.
