Mini- resource design for the dispersed resource unit which considers spatial frequency and transmission method

摘要

Being radio communication method and the device with the portable communications terminal and base station, the aforementioned method physical resource unit (PRU) includes the fact that you exchange between base station and the portable communications terminal. PRU includes plural OFDMA symbols. As for OFDMA symbol of the l turn eye of each PRU, n _{l which} is allotted with the pilot allotment system which is decided beforehand the pilot was included, L _{DRU which} among OFDMA symbols of the l turn eye remains (P _{sc n l}) the data subcarrier L _DRU (P _{sc n l}) to the 1 consecutively rinanbaringu was done from 0, continued logically and each subcarrier which rinanbaringu is done, L _DRU L _{pair and l} grouping was done in pair, L to _DRU L _{pair and l 1} rinanbaringu was done from 0, the tone which is continued logically - pair was beforehand decided in each pairPermutation formality is applied, includes the fact that among other things mapping it is done in ith dispersion LRU.
